NOTICE OF ACTION BY WRITTEN CONSENT
AND
INFORMATION STATEMENT

WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED
NOT TO SEND US A PROXY.

June 23, 2014

Dear Unitholder:

        This notice of action by written consent and the accompanying information statement are being furnished to the holders of common units ("Common Units") representing limited partner interests in PetroLogistics LP, a Delaware limited partnership (the "Partnership"), in connection with the Agreement and Plan of Merger and Membership Interest Transfer Agreement, dated as of May 27, 2014, by and among Flint Hills Resources, LLC, a Delaware limited liability company ("Parent"), FHR Propylene, LLC, a Delaware limited liability company and subsidiary of Parent ("Merger Sub"), the Partnership, PetroLogistics GP LLC, a Delaware limited liability company (our "general partner"), and Propylene Holdings LLC, a Delaware limited liability company. We refer to the Agreement and Plan of Merger and Membership Interest Transfer Agreement as the "Merger Agreement" and to the merger of Merger Sub with and into PetroLogistics that is contemplated by the Merger Agreement as the "Merger."

        Upon the consummation of the Merger, each Common Unit that is issued and outstanding immediately prior to the effective time of the Merger will be cancelled and converted automatically into the "Merger Consideration," which represents the right of (i) all unitholders, other than certain principal unitholders of the Partnership (the "Public Unitholders"), to receive cash consideration of $14.00 per Common Unit, without interest and subject to any required withholding taxes (the "Public Merger Consideration") and (ii) certain principal unitholders of the Partnership (the "Principal Unitholders"), owning in aggregate 72.9% of the outstanding Common Units, to receive cash consideration of $12.00 per Common Unit, without interest and subject to any required withholding taxes (the "Sponsor Merger Consideration"). In addition, we expect to pay to all Public Unitholders and all Principal Unitholders (together, the "Unitholders") of record on the day preceding the closing date of the Merger a one-time cash distribution in connection with and contingent upon the closing of the Merger, which will be calculated to approximate the distribution that would have otherwise been paid for the period through the closing date, less an additional reserve to cover a portion of the transaction-related costs of the Partnership. A copy of the Merger Agreement is included as Annex A to the accompanying information statement.

        The board of directors of our general partner unanimously approved the Merger Agreement, the Merger and the other transactions contemplated by the Merger Agreement (collectively with the Merger, the "Transactions") on the terms and subject to the conditions set forth in the Merger Agreement, declared the Merger Agreement and the Transactions to be advisable and in the best interest of the Partnership, our general partner and the Unitholders, and recommended that the Unitholders approve the Merger Agreement and Transactions.

        Under the applicable provisions of our First Amended and Restated Agreement of Limited Partnership (the "Partnership Agreement"), the approval of the Merger Agreement by the Unitholders required the affirmative vote or written consent of the holders of a majority of the outstanding Common Units. On May 27, 2014, the Principal Unitholders delivered to the Partnership a written consent approving the Merger Agreement. Accordingly, the approval of the Merger Agreement was effected on May 27, 2014. No further action of the Unitholders is required to approve the Merger Agreement. As a result, the Partnership has not solicited and is not soliciting your approval of the


Table of Contents

Merger Agreement. Further, the Partnership does not intend to call a meeting of Unitholders for purposes of voting on the approval of the Merger Agreement.

        In accordance with the applicable provisions of the Partnership Agreement, this notice of action by written consent and accompanying information statement is being mailed to Unitholders of record on May 27, 2014 as notice of the action by written consent to approve the Merger Agreement taken by the Principal Unitholders effective as of such date.

        We urge you to read the entire accompanying information statement carefully. No action by you is requested or required at this time. If the Merger is consummated, you will receive instructions regarding the surrender of your Common Units and payment for your Common Units.

    By order of the Board of Directors of PetroLogistics GP LLC,

 

 


SIG


Richard Rice
Senior Vice President, General Counsel and Corporate Secretary

        Neither the U.S. Securities and Exchange Commission nor any state securities or other regulatory agency has approved or disapproved the Merger, passed upon the merits or fairness of the Merger, or passed upon the adequacy or accuracy of the disclosures in this notice and information statement. Any representation to the contrary is a criminal offense.

        The accompanying information statement is dated June 23, 2014 and is first being mailed to Unitholders on or about June 24, 2014.

The Merger Agreement

        Each phantom unit granted pursuant to the PetroLogistics Long Term Incentive Plan (the "LTIP") outstanding immediately prior to the Effective Time ("Phantom Units"), whether or not vested, will, at the Effective Time, (i) be cancelled and converted into the right to receive an amount of cash, less required tax withholding, equal to the Public Merger Consideration plus the Merger Related Distribution (the "Phantom Unit Consideration"), (ii) no longer be outstanding, and (iii) cease to exist, upon the terms and subject to the conditions set forth in the Merger Agreement. Following the Effective Time, Parent will cause our general partner to pay the Phantom Unit Consideration in full satisfaction of all rights pertaining to the Phantom Units formerly outstanding to each holder of Phantom Units that executes and delivers an executed acknowledgement, with such payment generally to be made as promptly as practicable following delivery thereof.

        As more fully described in this information statement and the Merger Agreement, the consummation of the Merger depends on the satisfaction or waiver of several conditions. If these conditions are not satisfied or waived, the Merger will not be consummated. These conditions include, among others: (i) the expiration or early termination of the waiting period applicable to the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "Hart-Scott-

 

3


Table of Contents

Rodino Act"), (ii) the absence of certain legal impediments to the consummation of the Merger, (iii) the accuracy of the parties' representations and warranties, and (iv) the performance of the parties' obligations under the Merger Agreement. Additionally, the consummation of the Merger and the GP Equity Transfer is subject to, among other things, a requirement that our facility performs at a certain level of production for a period of four days prior to the Effective Time, and to the Partnership's receipt of a legal opinion regarding certain tax matters.

        The MLP Entities and GP Holdings have agreed that they, their subsidiaries and their respective officers, managers and directors will not, and will cause their respective affiliates and representatives (collectively, the "MLP Non-Solicit Parties") not to, among other things, (i) initiate, solicit or knowingly facilitate or encourage any inquiries, discussions regarding, or the making or submission of, any proposal, request or offer that constitutes, or could reasonably be expected to lead to, any alternative acquisition proposal, (ii) conduct, engage in, continue or otherwise participate in any discussions or negotiations regarding any alternative acquisition proposal, or (iii) furnish any non-public information or afford access to the books and records of the MLP Group Entities to any third party that is seeking to make, or has made, an alternative acquisition proposal. However, during the period from May 27, 2014 through 11:59 p.m. (Central Time) on July 6, 2014 (the "Unitholder Consent Period"), the MLP Non-Solicit Parties may provide information or afford access to the books and records of the MLP Group Entities and engage or participate in discussions or negotiations with third parties making unsolicited written bona fide acquisition proposals, as long as the MLP Entities have delivered notice of such bona fide acquisition proposal to Parent, such third parties have executed confidentiality and standstill agreements, the MLP Entities have disclosed to Parent the information to be provided, and the Board of Directors has determined in good faith, after consultation with outside advisors, that such proposal either constitutes or is reasonably likely to result in a superior proposal.

        Prior to the end of the Unitholder Consent Period, the Board of Directors may withdraw its recommendation regarding the Merger if it determines, after complying with specified procedures, which include customary "match rights" in favor of Parent, that a bona fide alternative acquisition proposal constitutes a superior proposal or that an intervening event has occurred and is continuing, and if the Board of Directors determines in good faith after consultation with its outside advisors that the Merger Agreement, the Merger and the other Transactions are not in the best interests of the Unitholders.

        The Merger Agreement contains certain termination rights for both the Partnership and Parent including, among others, (i) by mutual agreement of Parent and the Partnership, (ii) by either the Partnership or Parent, in the event that a court issues a final, non-appealable order or injunction prohibiting the Merger, or in the event that the Merger has not been consummated on or before November 27, 2014, subject to extension to May 27, 2015, in certain circumstances specified in the Merger Agreement (the "Outside Date"), (iii) by the Partnership, in the event the Board of Directors has withdrawn its recommendation that the Unitholders approve the Merger and Merger Agreement, and (iv) by Parent, in the event that an MLP Entity or GP Holdings has breached the non-solicit obligations under the Merger Agreement or the Board of Directors has withdrawn its recommendation that the Unitholders approve the Merger and Merger Agreement.

        Upon termination of the Merger Agreement under specific circumstances, the Partnership will be required to pay Parent a termination fee of $57,000,000 (the "MLP Termination Fee"). If the Merger Agreement is terminated due to the passing of the Outside Date or upon a breach of the Partnership's

 

4


Table of Contents

covenants (other than the Partnership's non-solicitation obligations) under the Merger Agreement, and the Partnership enters into an alternative acquisition agreement within 12 months of such termination, the MLP Termination Fee is payable. The MLP Termination Fee is also payable in the event, among other things, that Parent terminates the Merger Agreement due to the Partnership's breach of the non-solicit provisions in the Merger Agreement, excluding breaches that are de minimis in nature and do not adversely affect Parent or the Transactions, or if the Board of Directors withdraws its recommendation that the Unitholders approve the Merger and the Merger Agreement. The Merger Agreement also provides that Parent will be required to pay a termination fee to MLP of $57,000,000 (the "Parent Termination Fee") if the Merger Agreement is terminated under certain circumstances.

        For a discussion of the fee payable under specific circumstances by the Sponsors to Parent, see "Support Agreements."

        The Hart-Scott-Rodino Act provides that transactions such as the Merger may not be consummated until certain information has been submitted to the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice and certain waiting period requirements have been satisfied. On June 6, 2014, the Partnership and Parent each filed a Notification and Report Form with the Federal Trade Commission and the Antitrust Division of the Department of Justice and requested an early termination of the waiting period. If the early termination is not granted and a request for additional information is not made by the relevant antitrust authorities, the waiting period will expire at 11:59 p.m. (Eastern Time) on July 7, 2014.

        Under the Merger Agreement, both the Partnership and Parent have agreed to cooperate with each other and use their respective reasonable best efforts to obtain all required governmental approvals and avoid any action or proceeding by a governmental entity to the extent necessary, proper or advisable to consummate the Merger, subject to exceptions for any divestitures or similar actions that may be required of the parties. Except as noted above with respect to the required filings under the Hart-Scott-Rodino Act, the expiration of 20 days from the dissemination of this information statement to our Unitholders and the filing of a certificate of merger in Delaware on the closing date of the Merger, we are unaware of any material federal, state or foreign regulatory requirements or approvals required for the execution of the Merger Agreement or consummation of the Merger or the other Transactions.

The Support Agreements (Page 81)

        On May 27, 2014, the Principal Unitholders entered into Support Agreements with Parent and Merger Sub, pursuant to which the Principal Unitholders agreed to deliver, immediately following the execution and delivery of the Support Agreements and the Merger Agreement, a written consent approving the Merger Agreement and the Transactions. Furthermore, the Principal Unitholders have agreed not to dispose of their Common Units unless certain conditions specified in the Support Agreements are satisfied. In addition, the Sponsors have agreed to pay to Parent 50% of any proceeds in excess of the Sponsor Merger Consideration (up to $50,000,000) upon consummation of an alternative proposal if (i) the Partnership is obligated to pay the MLP Termination Fee and (ii) within 12 months, any MLP Group Entity, GP Holdings or any of their respective affiliates has entered into an agreement with respect to, or approved or recommended to the Partnership's limited partners or otherwise not opposed, an alternative proposal.

Opinions of Our Financial Advisors (Page 34)

        The Board of Directors retained Morgan Stanley & Co. LLC ("Morgan Stanley") as financial advisor to provide a financial opinion letter in connection with the Merger. The Board of Directors selected Morgan Stanley to act as its financial advisor based on Morgan Stanley's qualifications, expertise and reputation and its knowledge of the business and affairs of the Partnership. At the meeting of the Board of Directors on May 27, 2014, Morgan Stanley rendered to the Board of Directors its oral opinion, subsequently confirmed in writing, that, as of such date and based upon and subject to the assumptions made, specified work performed, procedures followed, matters considered, and qualifications and limitations on the scope of the review undertaken by Morgan Stanley as set forth in the written opinion, the Public Merger Consideration pursuant to the Merger Agreement was fair, from a financial point of view, to the Public Unitholders.

        The full text of the written opinion of Morgan Stanley, dated May 27, 2014, is included as Annex C to this information statement and is incorporated by reference in its entirety into this information statement. The opinion sets forth, among other things, the assumptions made, specified work performed, procedures followed, matters considered and qualifications and limitations on the scope of the review undertaken by Morgan Stanley in rendering its opinion. You should read the opinion carefully and in its entirety. Morgan Stanley's opinion was directed to the Board of Directors and addresses only the fairness from a financial point of view of the Public Merger Consideration pursuant to the Merger Agreement to the Public Unitholders as of the date of the opinion. It does not address any other aspect of the Merger or other Transactions. In addition, Morgan Stanley's opinion did not in any manner address the prices at which the Common Units would trade at any time. The opinion does not constitute a recommendation with respect to the Merger or other Transactions. The summary of the opinion of Morgan Stanley set forth in this information statement is qualified in its entirety by reference to the full text of the opinion included as Annex C to this information statement.

        On May 27, 2014, Evercore Group, L.L.C. ("Evercore") delivered its oral opinion to the Board of Directors, which opinion was subsequently confirmed by delivery of a written opinion dated May 27, 2014, to the effect that, as of such date and based upon and subject to assumptions made, matters considered and limitations on the scope of review undertaken by Evercore as set forth in its opinion, the Public Merger Consideration pursuant to the Merger Agreement was fair, from a financial point of view, to the Public Unitholders.

        The full text of the written opinion of Evercore, dated May 27, 2014, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is included as Annex D to this information statement. You are urged to read Evercore's opinion carefully and in its entirety. Evercore's opinion was addressed to, and provided solely for the information and benefit of, the Board of Directors (in its capacity as such), in connection with its evaluation of the Merger and addresses only the fairness, from a financial point of view, of the Public Merger Consideration to the Public Unitholders. The opinion did not address any other aspect of the Merger and does not constitute a recommendation in respect of the Merger or other Transactions. Evercore's opinion did not address the relative merits of the Merger as compared to other business or financial strategies that might be available to the Partnership, nor did it address the underlying business decision of the Partnership to engage in the Merger. The summary of the Evercore opinion set forth herein is qualified in its entirety by reference to the full text of the opinion included as Annex D to this information statement.

Financing (Page 54)

        The Merger is not contingent on the receipt of any proceeds from any financing.

Recommendation of the Board of Directors (Page 29)

        After consideration, the Board of Directors:

        For a discussion of the material factors considered by the Board of Directors in reaching their conclusion, see "The Merger—Reasons for the Merger."

The Written Consent of Unitholders (Page 70)

        Our Partnership Agreement provides that the affirmative vote or written consent of limited partners holding a majority of the outstanding Common Units is required to approve the Merger Agreement. On May 27, 2014, the Principal Unitholders, which together owned 72.9% of the Common Units then outstanding, delivered to the Partnership a written consent approving the Merger Agreement and the Transactions. As a result, no other Unitholder vote is necessary to approve the Merger Agreement, and your approval is not required and is not requested. If the Merger Agreement is terminated in accordance with its terms, the written consent of the Principal Unitholders will be of no further force and effect.

        Federal securities laws provide that the Merger may not be consummated until 20 days after the date of mailing of this information statement to our Unitholders. In addition, the Merger Agreement provides the closing may not occur prior to the end of the Unitholder Consent Period. Notwithstanding the execution and delivery of the written consent, the Merger will not occur until these time periods have elapsed and all conditions to closing related to any regulatory requirements are satisfied. We expect the Merger to be consummated before November 27, 2014; however, there can be no assurance that the Merger will be consummated at that time, or at all.

        When actions are taken by written consent of less than all of the Unitholders entitled to vote on a matter, our Partnership Agreement requires that notice of the action be provided to those Unitholders who did not consent. This information statement and the notice that it accompanies constitute notice to you of action by written consent as required by our Partnership Agreement.

Interests of Directors and Executive Officers in the Merger (See Page 56)

        Some of our executive officers and the members of the Board of Directors have interests in the Merger that are different from, or in addition to, the interests of our Unitholders generally.

        These interests include:

Litigation Related to the Merger (See Page 63)

        On June 2, 2014, a putative Unitholder class action complaint, captioned Klemesrud v. PetroLogistics LP, et al., C.A. No. 9723-VCP (the "Klemesrud Action"), was filed in the Court of Chancery of the State of Delaware (the "Delaware Court"). Between June 4 and June 19, 2014, two additional putative Unitholder class action complaints, captioned Swanson v. PetroLogistics LP, et al., C.A. No. 9737-VCP (the "Swanson Action") and Henry v. PetroLogistics LP, et al., C.A. No. 9759-VCP (the "Henry Action"), were filed in the Delaware Court, and two additional putative Unitholder class action complaints, captioned Basaraba v. PetroLogistics LP, et al., No. 4:14-cv-1558 (the "Basaraba Action") and Wolfson v. PetroLogistics LP, et al., No. 4:14-cv-1723 (the "Wolfson Action"), were filed in the United States District Court for the Southern District of Texas, Houston Division (the "Texas Federal Court"). Each of the complaints names the MLP Entities, the members of the Board of Directors, GP Holdings and the Parent Entities as defendants. The complaints in the Klemesrud Action and the Henry Action also name Koch Industries, Inc. or Koch Industries, LLC as defendants. In each of the complaints, the plaintiffs generally allege that the members of the Board of Directors breached their duties to the Unitholders by entering into the Merger Agreement and further allege that the other defendants aided and abetted the alleged breaches of duty by the members of the Board of Directors. The Henry Action also alleges that the defendants breached the terms of our Partnership Agreement, and the Wolfson Action alleges that the defendants violated Sections 14(a) and 20(a) of the Exchange Act by issuing an information statement that omits and/or misrepresents material information concerning the Merger. In each complaint, the plaintiffs seek, among other things, to enjoin the Merger and/or money damages.

Q.
WILL THE MERGER CONSIDERATION I RECEIVE IN THE MERGER INCREASE IF THE PRICE OF THE PARTNERSHIP'S COMMON UNITS INCREASES ABOVE THE MERGER CONSIDERATION?

A.
No. The Merger Consideration is fixed. The Merger Agreement does not contain any provision that would adjust the Merger Consideration (in either direction) based on fluctuations in the price of our Common Units. The Partnership expects, however, to make a final one-time cash distribution in connection with, and conditioned upon, the closing of the Merger, which will be calculated to approximate the distribution that would have otherwise been paid for the period through the closing date of the Merger, subject to an additional reserve of $12.3 million to cover a portion of the Transaction-related costs of the Partnership. The record date for the final one-time cash distribution will be the business day immediately before the closing date of the Merger.

Q.
WILL THE PARTNERSHIP CONTINUE TO PAY QUARTERLY DISTRIBUTIONS?

A.
The Partnership expects to continue to make distributions consistent with its historical distribution policy through the closing date of the Merger. If the closing date occurs before the announced record date for any quarterly distribution, the record date for such quarterly distribution will be the business day immediately before the closing date of the Merger.

Q.
IS THE MERGER SUBJECT TO THE FULFILLMENT OF CERTAIN CONDITIONS?

A.
Yes. Before consummation of the Merger, several closing conditions must be satisfied or waived. If these conditions are not satisfied or waived, the Merger will not be consummated. For example, the consummation of the Merger is subject to the satisfaction or waiver of certain customary conditions, including, among others: (i) the expiration or early termination of the waiting period applicable to the Merger under the Hart-Scott-Rodino Act, (ii) the absence of certain legal impediments to the consummation of the Merger, (iii) the accuracy of the parties' representations and warranties, and (iv) the performance of the parties' obligations under the Merger Agreement. Additionally, the consummation of the Merger is subject to, among other things, a requirement that our facility perform at a certain level of production for a period of four days prior to the Effective Time, and to our receipt of a legal opinion regarding certain tax matters. See "The Merger Agreement—Conditions to the Merger."

A.
No. Under the Delaware Revised Uniform Limited Partnership Act and our Partnership Agreement, no dissenters or appraisal rights are or will be available in connection with the Merger or the other Transactions.

WHEN IS THE MERGER EXPECTED TO BE CONSUMMATED?

A.
We expect the Merger to be consummated before November 27, 2014. However, there can be no assurance that the Merger will be consummated by that time, or at all.

Q.
WILL I OWE TAXES AS A RESULT OF THE MERGER?

A.
The Merger will be a taxable transaction for holders of our Common Units, including for non-U.S. holders (because part or all of a non-U.S. holder's gain from the surrender of its Common Units may be treated as effectively connected with the Unitholder's indirect U.S. trade or business constituted by its investment in the Partnership). As a result, any gain you recognize as a result of the Merger will be subject to U.S. federal income tax and also may be taxed under applicable state, local or other tax laws. See "The Merger—Material U.S. Federal Income Tax Consequences of the Merger to Our Unitholders." You are urged to consult your own tax advisors as to the particular consequences of the Merger to you, including the applicability of federal, local, foreign and other tax laws.

THE MERGER

Background

        Since 2012, our management and the Board of Directors have regularly considered the Partnership's prospects to grow its business and increase value for the Unitholders. The focus in 2012 and early 2013 was primarily on growth opportunities involving asset acquisitions, joint ventures and expansion projects. In connection with these efforts, members of our management and Lance L. Hirt and Jaime Buehl-Reichard, two members of the Board of Directors affiliated with Lindsay Goldberg, held discussions from time to time with a number of industry participants, including Company G discussed below, that they viewed as having businesses or assets that had a potential strategic fit with or provided an acquisition opportunity for the Partnership. During this same time, our management and the Board of Directors also had discussions from time to time regarding secondary sales of Common Units held by the Sponsors to the public, though no such sales were ever consummated.

        As part of its efforts to explore growth opportunities, on April 30, 2013, David Lumpkins and Nathan Ticatch, our co-principal executive officers and Founding Unitholders, attended a meeting with Parent to discuss various strategic transactions, including the potential acquisition by the Partnership of one of Parent's assets (the "Asset Acquisition") with the Partnership using Common Units to fund the purchase price. A possible acquisition by Parent of the Partnership was not discussed at this meeting. In connection with the Partnership's consideration of the Asset Acquisition, Parent and the Partnership executed a confidentiality agreement on May 22, 2013. Over the following months, the Partnership conducted diligence on the asset, representatives from Parent conducted diligence regarding the Partnership and representatives from Parent and the Partnership held various calls and meetings to discuss their respective businesses and the Asset Acquisition.

        Also as part of these efforts, on May 20, 2013, Messrs. Lumpkins and Ticatch met with representatives from a company (Company A) to discuss various potential strategic activities that the Partnership and Company A might pursue together. A possible acquisition by Company A of the Partnership was not discussed at this meeting. Company A and the Partnership had executed a confidentiality agreement on May 10, 2013 in anticipation of the meeting.

        On May 23, 2013, Messrs. Lumpkins and Hirt and Ms. Buehl-Reichard met with representatives of Morgan Stanley to discuss a potential sale of some or all of the outstanding Common Units. The parties discussed potential acquirers of the Common Units, including chemical and oil and gas corporations, as well as master limited partnerships and potential acquirers from Europe, Asia and the Middle East. Based on these discussions, six companies, in addition to Company A, were identified as most likely to be interested in acquiring some or all of the Common Units. Thereafter it was decided that four of the companies (Companies B, C, D and E, respectively) would be contacted by Morgan Stanley and one (Company F) would be contacted by both Morgan Stanley and a representative from Lindsay Goldberg due to a specific relationship between Lindsay Goldberg and Company F. It was also decided that the last of these companies (Company G) would be contacted by Messrs. Lumpkins and Ticatch at a later time when they felt it was appropriate due to ongoing discussions with Company G regarding a potential growth project. It was also decided that Messrs. Lumpkins and Ticatch would continue to engage with Company A and Parent on various growth opportunities.

        Prior to the May 23, 2013 meeting with Morgan Stanley, representatives of Lindsay Goldberg had initial contact with an oil and gas company (Company H) with respect to a potential transaction completely unrelated to the Partnership, but during those discussions Company H noted that it might have a potential interest in the Partnership as well. Based on such discussions, on May 28, 2013, representatives from Company H met with Mr. Lumpkins and visited the Partnership's facility in Houston.

        In June 2013, Company A discussed with Messrs. Lumpkins and Ticatch expanding the scope of the discussions to include a potential investment by Company A in the Partnership. Thereafter,

Table of Contents

Company A commenced diligence on the Partnership, which included a management meeting on June 12, 2013 and access to additional information on the Partnership.

        In June 2013, Morgan Stanley contacted Companies B, C, D and E to gauge their interest in a possible transaction with the Partnership. Three of the targeted companies were chemical companies, of which two (Company B and Company C) indicated to Morgan Stanley that they were not interested in a potential acquisition of the Partnership. The third company (Company D) indicated to Morgan Stanley that it considered the public stock market valuation of the Partnership to be high and it had no interest in pursuing an acquisition. The average NYSE closing sale price of the Common Units for the month of June 2013 was $12.45 per Common Unit. The fourth company (Company E) indicated to Morgan Stanley that it had other priorities and was not interested in pursuing discussions regarding a potential acquisition of the Partnership.

        After being contacted by Morgan Stanley and a representative from Lindsay Goldberg in June 2013, Company F indicated a potential interest in acquiring some or all of the Common Units and requested two weeks to review the publicly available information. Following such review, Company F reported back to a representative from Lindsay Goldberg that it was not interested in pursuing discussions.

        In mid-July 2013, Company A informed the Partnership that its valuation analysis resulted in a price for the Partnership that would be significantly below the price at which the Common Units were then trading in the market and that it was unwilling to make an offer for the Partnership. The average NYSE closing sale price of the Common Units for the month of July 2013 was $13.15.

        On July 18, 2013, at the invitation of an investment bank, Mr. Hirt and Ms. Buehl-Reichard had preliminary conversations concerning the Partnership with an international conglomerate that had not been previously identified as a potential acquirer (Company I). Company I did not engage in any significant respect and expressed no interest in acquiring the Partnership.

        On July 23, 2013, Messrs. Lumpkins and Ticatch met with members of senior management of Parent to further discuss their respective businesses and the Asset Acquisition.

        In late August 2013, after discussions with Company G regarding a growth-related project which ultimately was not consummated, Mr. Lumpkins contacted the CEO of Company G to explore Company G's interest in a potential acquisition of some or all of the Common Units. Subsequently, Messrs. Lumpkins and Ticatch and Ms. Buehl-Reichard had a phone call with the senior management of Company G to discuss the Partnership's operations and provide a financial overview of the Partnership. Company G signed a confidentiality agreement on August 28, 2013. On September 12, 2013, Messrs. Lumpkins and Hirt had a meeting with senior members of the management of Company G and discussed potential transaction structures. Following a month of diligence, Company G indicated orally in October 2013 that the highest price it would be able to offer was at the lower end of a $9.00 - $10.00 range per Common Unit (which was substantially below the average NYSE closing sale price for the month of October 2013 of $12.13 per Common Unit) but there was no assurance that, following the completion of full diligence and a strategic analysis, Company G would remain interested in consummating a transaction at that price. No further conversations were held between Company G and the Partnership based on that response.

        On September 12, 2013, at the invitation of an investment bank, Mr. Hirt and Ms. Buehl-Reichard met with representatives from a company that had not been previously selected to be contacted in the May 2013 conversations with Morgan Stanley (Company J) and discussed, among other topics, the possibility of Company J acquiring some or all of the Common Units. Throughout September and October 2013, a confidentiality agreement was negotiated between the Partnership and Company J; however, it was not executed. Company J, through its investment banker, requested a follow-up meeting with Lindsay Goldberg in November, which was held on November 5, 2013. After that follow-up meeting, the investment bank informed Lindsay Goldberg that there was nothing further to discuss.

        On October 4, 2013, Messrs. Lumpkins and Ticatch again met with members of senior management from Parent to further discuss their respective businesses and the Asset Acquisition.

        On November 7, 2013, Mr. Hirt had a meeting with a member of senior management of Company H, at which they discussed the acquisition by Company H of some or all of the Common Units. At the November 7, 2013 meeting, Company H's representative expressed some initial interest in a transaction, and a confidentiality agreement was executed between the Partnership and Company H on November 21, 2013. However, Company H never indicated any further interest in the Partnership and there were no further discussions.

        Throughout November 2013, Parent and the Partnership continued to have discussions regarding their respective businesses. During this time, Parent and the Partnership exchanged additional financial information. In December 2013, Mr. Lumpkins and Anthony J. Sementelli, the Chief Financial Officer of Parent, discussed shifting the focus of their conversations from the Asset Acquisition to alternative ways that the two companies could synergistically work together.

        On February 11, 2014, Messrs. Lumpkins, Ticatch and Hirt attended a meeting with members of Parent's senior management. At the meeting, Parent indicated that it might be interested in acquiring the Partnership, through a merger or otherwise. After the meeting, the Partnership began sharing additional selected financial information with Parent pursuant to the confidentiality agreement with Parent dated as of May 22, 2013.

        On February 26, 2014, members of Parent's senior management met with Messrs. Lumpkins and Ticatch and Ms. Buehl-Reichard to discuss the Partnership's business. Following the meeting, certain members of Parent's senior management visited the Partnership's facility in Houston with Mr. Ticatch.

        Throughout the month of March 2014, Parent conducted financial due diligence with respect to the Partnership.

        On March 6, 2014, Messrs. Hirt and Sementelli participated in a conference call to discuss potential structures for a transaction between the Partnership and Parent. Later that same day, Mr. Lumpkins and Ms. Buehl-Reichard and representatives from Vinson & Elkins LLP ("V&E") and Weil, Gotshal & Manges LLP ("Weil"), counsel to the Partnership, held a conference call to discuss a potential transaction with Parent, including potential structures for such a transaction.

        On March 27, 2014, Messrs. Hirt and Sementelli participated in a conference call. During the discussions, Mr. Sementelli made an oral indication of a $12.00 per Common Unit offer price. Mr. Hirt suggested to Mr. Sementelli that the Board of Directors was unlikely to find such an offer acceptable. On March 27, 2014, the NYSE closing sale price of the Common Units was $12.60 per Common Unit.

        On March 31, 2014, Messrs. Hirt and Sementelli participated in a conference call. Mr. Sementelli indicated that Parent would be willing to offer $12.35 per Common Unit, but that this price was the highest price Parent was willing to offer and Parent was not prepared to have its offer shopped to competing bidders and would only participate in an exclusive process. In addition to the $12.35 per Common Unit offer, Messrs. Hirt and Sementelli also discussed a one-time cash distribution to be paid to all Unitholders in connection with the consummation of the Merger. On March 31, 2014, the NYSE closing sale price of the Common Units was $12.44 per Common Unit.

        On April 3, 2014, the Partnership received a written indication of interest (the "Indication of Interest") from Parent to acquire all of the Partnership's outstanding Common Units for $12.35 per unit in cash (the "Potential Transaction"). The Indication of Interest noted that the Potential Transaction would include the transfer, for no or nominal consideration, of the non-economic general partner interest in the Partnership to Parent. The Indication of Interest also stated that Parent expected that the Partnership would transact exclusively with Parent and that Parent would not participate in anything other than an exclusive process. On April 3, 2014, the NYSE closing sale price of the Common Units was $12.95 per Common Unit.

Table of Contents

        On April 3 and April 4, 2014, Mr. Lumpkins held conference calls with each of the independent members of the Board of Directors to inform them of the receipt of the Indication of Interest.

        On April 8, 2014, the Board of Directors held a meeting at the Houston offices of V&E. Representatives from V&E, Weil, Morgan Stanley and Morris, Nichols, Arsht & Tunnel LLP, special Delaware counsel to the Partnership ("MNAT"), also attended the meeting. During the meeting, the Board of Directors discussed the Indication of Interest and considered various responses to Parent. Mr. Lumpkins discussed and answered questions concerning the background leading to the Partnership's receipt of the Indication of Interest. Mr. Lumpkins and Mr. Hirt further reviewed the various meetings and discussions that had taken place with Parent over the preceding months. Mr. Hirt informed the Board of Directors that prior to the receipt of the Indication of Interest, Parent had communicated an oral indication of a $12.00 per Common Unit offer to which Mr. Hirt responded that the Board of Directors was unlikely to find such an offer acceptable. Mr. Hirt noted that in response, Parent later indicated they would increase the offer to $12.35 per Common Unit but they would not go any higher. Mr. Lumpkins noted that the number of Common Units outstanding as set forth in the Indication of Interest and as used by Parent to arrive at its offer price did not include the Phantom Units that had been awarded under the LTIP, which were disclosed in the Partnership's public filings. Mr. Lumpkins stated that after receipt of the Indication of Interest he called Mr. Sementelli to inform him of the discrepancy regarding the number of Common Units.

        At the April 8 meeting of the Board of Directors, representatives from Morgan Stanley discussed with the Board and answered questions regarding their preliminary situation analysis with respect to the Indication of Interest. The Morgan Stanley representatives discussed, among other things, dynamics and potential headwinds in the industry, including industry forecasts for the demand and supply of propylene and propane, the anticipated construction of PDH facilities by other industry participants, and the possible pressure on the propane-to-propylene spread. All of these factors could negatively impact the price of the Common Units in the future, the Partnership's performance over time and precedent master limited partnership transactions and general macroeconomic conditions. Morgan Stanley noted that after consideration of the potential future downside risks facing the Partnership and its business, it believed there was a risk that the then-current stock market price of the Common Units would not be maintained. The Morgan Stanley representatives also discussed the prior contacts with other potentially interested parties that had taken place between May 2013 and November 2013 and noted that no party expressed any significant strategic interest in the Partnership as a result of those prior contacts. In addition, Morgan Stanley disclosed prior work it had done for the Partnership, Lindsay Goldberg and its affiliates and Parent and its affiliates over the past three years. Based on Morgan Stanley's disclosure of the previous work it had done for the Partnership, Lindsay Goldberg and its affiliates and Parent and its affiliates, the Board of Directors determined that, although it had confidence in Morgan Stanley's ability to serve as the Partnership's financial advisor, that, should the Board of Directors decide to proceed with discussions with Parent about the Potential Transaction, it would be prudent to engage another financial advisor that was independent from all relevant parties to provide a second fairness opinion to the Board of Directors.

        Representatives from Weil then made a presentation to the Board of Directors at the April 8, 2014 meeting and answered questions regarding potential responses to the Indication of Interest. As part of its presentation, representatives from Weil also discussed and reviewed the obligations of the Board of Directors under the Partnership's governing documents and applicable law in connection with its consideration of the Indication of Interest. Weil also disclosed prior work it had done for Parent and its affiliates, the Partnership and Lindsay Goldberg and its affiliates in the past. V&E and MNAT made similar disclosures with respect to prior work they had done for Parent and its affiliates and the Partnership in the past. The Board of Directors engaged in a discussion with the members expressing their views on the Potential Transaction and whether it was the right time and in the best interests of the Unitholders to engage in a transaction at the current time. As part of the discussion, the Board of Directors discussed the previous contacts made to potentially interested parties in 2013 and the results

of those contacts. During the discussion, Mr. Ticatch noted that he was more optimistic about the ability of the Partnership to improve its performance and thereby improve the public stock market price of the Common Units over time than some of the other directors. As a result, Mr. Ticatch was not convinced that this was the right time for the Board of Directors to sell the Partnership. Mr. Ticatch explained that he saw potential growth opportunities for the Partnership, including through the successful execution of possible plant expansion plans, which could significantly enhance the Partnership's financial performance. Mr. Ticatch acknowledged, however, that such expansion projects would entail risk and could require substantial capital expenditures to complete. The Board of Directors discussed the potential costs, benefits, and risks associated with the plant expansion projects and then discussed whether the potential plant expansion projects could be potentially used to negotiate an increased offer price from Parent. The Board of Directors further discussed Parent's request for exclusivity and whether it believed proceeding on such a basis was in the best interests of the Unitholders. As part of its discussion, the Board of Directors considered the terms of the Indication of Interest and Mr. Sementelli's communication to Messrs. Hirt and Lumpkins that Parent was not prepared to have its offer shopped and that it would withdraw from the process before allowing that to occur. After weighing the likelihood of receiving a greater offer for the Common Units in either a pre- or post-signing market check against the risk that Parent may withdraw its offer, which the Board of Directors believed to be a meaningful risk, the Board of Directors concluded that the Partnership should proceed with discussions with Parent concerning the Potential Transaction and agree to Parent's request for exclusivity. Mr. Ticatch abstained from the decision to proceed with discussions with Parent concerning the Potential Transaction. The Board of Directors also voted to seek financial advisors to provide an additional fairness opinion to the Company in connection with the Potential Transaction. Finally, the Board of Directors appointed an ad-hoc transaction committee (the "Transaction Committee") to oversee discussions with Parent, negotiate with Parent and select the second financial advisor. The Board of Directors appointed Messrs. Lumpkins, Ticatch and Hirt and Ms. Buehl-Reichard to the Transaction Committee.

        On April 9, 2014, Parent and the Partnership executed a new confidentiality agreement in light of the expanded discussions between the parties regarding the Potential Transaction. The new confidentiality agreement covered confidential information provided to Parent by the Partnership since March 1, 2014.

        On April 12, 2014, Jones Day, counsel to Parent, sent a draft merger agreement to the Partnership and Weil. Weil, with the assistance of V&E and MNAT, began its review of the merger agreement.

        On April 14, 2014, the Transaction Committee held a telephonic meeting. Representatives from Weil and V&E also attended the meeting. Weil reviewed the key provisions of the draft merger agreement with the committee and noted that the draft contained significant deal uncertainty because of the conditions, representations, and warranties sought by Parent. Among the conditions highlighted by Weil was the requirement of a specific amount of working capital at closing and a condition that no merger-related litigation be in existence at the time of closing. The Transaction Committee expressed its concern over the provisions and instructed Weil to push back on these conditions sought by Parent. Representatives from Weil also reviewed the proposed structure of the Potential Transaction, including the requirement that Lindsay Goldberg and York Capital sign written consents approving the Potential Transaction concurrent with the execution of the merger agreement and the lack of a termination right to accept a better offer after signing. The Transaction Committee instructed Weil to propose alternative structures to Parent and its counsel that would allow the Partnership the ability to accept a superior offer post-signing. The Transaction Committee further instructed Weil to make clear to Parent and its counsel that they viewed Parent's offer as being $12.35 for all outstanding Common Units, and for Phantom Units issued under the LTIP. The Transaction Committee further discussed the need for merger agreement provisions to permit cash distributions to the Unitholders through the time of closing and instructed Weil to raise the issue in its discussions with Parent and its counsel.

        Also on April 14, 2014, representatives from the Partnership, Weil, V&E, Parent and Jones Day held a due diligence conference call to discuss tax matters.

        On April 15, 2014, representatives from Parent, Jones Day and the Partnership held in-person due diligence sessions at the Houston offices of V&E. The diligence meetings covered corporate matters, environmental issues, intellectual property, facility operations, finance and accounting matters and employee benefits and human resources matters.

        On April 16, 2014, representatives from Parent, Jones Day, the Partnership, Weil and V&E held a meeting at the Dallas offices of Weil. The parties discussed the Indication of Interest and certain provisions in the draft merger agreement. During the meeting, representatives from Weil and the Partnership presented the Partnership's concerns regarding the closing conditions and the "locked-up" structure of the transaction that did not allow for a post-signing market check to take a superior offer. Weil also noted that the Board of Directors had authorized continued discussions with Parent and its counsel about the Potential Transaction only if the offer of $12.35 per Common Unit was applied to the Phantom Units issued under the LTIP in addition to the outstanding Common Units. Weil further explained that Parent's current offer required cancellation and delivery of the Phantom Units, and that by not including the Phantom Units in Parent's calculation of the offer price, Parent was effectively offering a price that was less than $12.35 per Common Unit. The parties also discussed the need for a final one-time cash distribution to the Unitholders prior to closing (the "Final Distribution") and the complexity associated with a working capital adjustment in a public transaction. The parties agreed to designate a working group comprised of representatives from each side to negotiate the merger agreement provisions relating to the Final Distribution. Additionally, Weil discussed the issue of employee retention both between signing and closing and post-closing and the importance of our employees to the operation of the facility. Weil also indicated that a no-litigation closing condition was unacceptable to the Partnership. Parent and Jones Day agreed to consider the issues raised by Weil and the Partnership, including a structure that provided for a termination right to accept a superior proposal after signing, and agreed to send a revised draft of the merger agreement the following week. Weil agreed to send a revised draft of the representations, warranties and covenants sections of the merger agreement to Jones Day by April 18, 2014.

        Later in the day on April 16, 2014, the Transaction Committee held a telephonic meeting. Representatives from Weil and V&E also attended the meeting. Representatives from Weil updated the Transaction Committee on the meeting with Parent and Jones Day. Weil informed the Transaction Committee that Parent understood the risk of the no-litigation closing condition, but that Parent would prefer to avoid the cost of post-closing transaction-related litigation. The members of the Transaction Committee discussed potential solutions and instructed Weil and V&E to develop alternative proposals. Weil reviewed its discussion with Parent regarding the Final Distribution and the Transaction Committee agreed to appoint Ms. Buehl-Reichard and Sharon Spurlin, the Partnership's Senior Vice President and Chief Financial Officer, to represent the Partnership on the working group that would negotiate the merger agreement provisions relating to the Final Distribution. Weil then summarized the discussions regarding the inclusion of the Phantom Units and noted that Parent stated inclusion of the Phantom Units would result in a decrease in the per Common Unit merger consideration. The Transaction Committee reaffirmed its position to Weil that the Phantom Units should be part of the Potential Transaction and that the per Common Unit merger consideration should not be decreased. Weil noted that Parent and its counsel had agreed to consider the Partnership's request for a structure that provided a termination right to accept a superior proposal after signing. Representatives from Weil and V&E discussed the other issues in the draft merger agreement with the Transaction Committee including employee retention matters, interim operating covenants and the Partnership's ability to enter into long-term material contracts prior to closing. Members of the Transaction Committee then discussed the engagement of Evercore to serve as the second financial advisor to the Partnership. Evercore had been identified among the various financial advisors that the Transaction Committee

19


Table of Contents

considered as having the requisite expertise and independence. The Transaction Committee instructed Weil to negotiate a customary engagement letter with Evercore for the committee's consideration.

        On April 18, 2014, Weil sent a revised draft of the representations, warranties, and covenants sections of the merger agreement to Jones Day.

        Also on April 18, 2014, Mr. Lumpkins and Mr. Sementelli had a call to discuss employee benefits matters wherein Mr. Lumpkins emphasized the need to treat all employees fairly and to take appropriate steps to ensure employee retention. Mr. Sementelli indicated that the Partnership's then-current proposal regarding employee benefits matters was expensive and Parent would consider further modifications provided the changes did not increase the overall costs.

        On April 21, 2014, the Board of Directors held a telephonic meeting. Representatives from Weil and V&E also attended the meeting. Representatives from Weil updated the Board of Directors on the events of the previous week and summarized the meetings that had taken place with Parent and Jones Day. Weil also discussed and answered questions concerning the open issues in the merger agreement proposed by Parent. During the meeting, Mr. Ticatch informed the Board of Directors about an operational issue at the Partnership's facility. Mr. Ticatch stated that a fracture had been discovered in one of the facility's reactors and that experts had been dispatched to assess the situation and to propose solutions. Mr. Ticatch noted that repair of the fracture may require the facility to be shut down for several days. The Board of Directors discussed the impact of the fracture and the repair on the timing of the Potential Transaction. Mr. Lumpkins then informed the Board of Directors that the Transaction Committee was recommending Evercore to act as a second financial advisor to the Partnership in connection with the Potential Transaction. It was noted that the Transaction Committee was recommending Evercore because it had the requisite expertise and had not provided services to the Partnership, Lindsay Goldberg or its affiliates or Parent or its affiliates in the past two years. The Board of Directors voted unanimously to engage Evercore. The Board of Directors also discussed the then-current trading price of the Common Units and how the increased trading price might impact the Potential Transaction, including Unitholder perspectives on the Potential Transaction if it were announced at or below the then-current trading price. A discussion ensued concerning the fundamental drivers of the price of Common Units. Following discussion, the Board of Directors instructed the Transaction Committee to determine whether potential expansion projects that were being contemplated by management could be used as a basis for negotiating a higher price with Parent. On April 21, 2014, the NYSE closing sale price of the Common Units was $12.38 per Common Unit.

        Throughout the week of April 21, 2014, representatives of the Partnership and Parent held due diligence conference calls on environmental matters, insurance matters and employee benefits and human resources.

        On April 22, 2014, representatives from the Partnership, Weil, Parent and Jones Day held a conference call to discuss the status of the merger agreement and open issues.

        On April 23, 2014, Jones Day sent a revised draft of the merger agreement to the Partnership and Weil. The revised draft of the merger agreement included a termination right for a superior proposal during a "window shop" period with related termination fee and expense reimbursement obligations to be paid by the Partnership. The revised draft also proposed to eliminate the no-litigation closing condition as long as Lindsay Goldberg was prepared to provide certain indemnification obligations for transaction-related litigation. Additionally, the revised merger agreement contemplated that all of the Phantom Units would be cancelled at the closing of the transaction and converted into the right to receive the merger consideration but that Parent would pay for only half of the costs related to the Phantom Units.

        Also on April 23, 2014, Jones Day sent first drafts of the support agreements for Lindsay Goldberg and York Capital to Weil. In the first drafts of the support agreements, Parent requested Lindsay

20


Table of Contents

Goldberg and York Capital to consent to the Potential Transaction upon signing. In addition, the draft support agreement provided for a termination fee in the amount of 50% of any proceeds in excess of the merger consideration (up to $50,000,000) received in an alternative transaction. The termination fee would be payable by Lindsay Goldberg and York Capital to Parent upon consummation of an alternative proposal.

        Also on April 23, 2014, the designated representatives from Parent and the Partnership participated in a conference call to discuss the mechanics for the Final Distribution. Later that day, a representative from Parent called Ms. Buehl-Reichard to inform her that Parent was withdrawing the request for a closing condition of a specific amount of working capital at closing. Representatives from Parent and the Partnership continued to hold discussions and negotiations regarding the merger agreement provisions relating to the Final Distribution from April 23, 2014 through May 27, 2014.

        On April 24, 2014, representatives from Parent, Jones Day, the Partnership and Weil held a meeting at the Dallas offices of Jones Day. The parties discussed the revised merger agreement and the related unresolved issues. Representatives from Weil and the Partnership stated that while the addition of a termination right for a superior proposal during a "window shop" period was a positive development, Parent's request for an indemnity agreement for transaction-related litigation and its proposal of paying for only half of the costs related to the Phantom Units were unacceptable to the Partnership. Weil stated that Parent's proposal related to the Phantom Units still resulted in less than $12.35 per unit when full vesting and payout of the Phantom Units was taken into account. Weil noted that it would address these issues in its comments to of the merger agreement. The parties agreed that representatives from Parent and the Partnership would continue to negotiate the merger agreement provisions relating to the Final Distribution.

        On April 25, 2014, the Board of Directors held a telephonic meeting. Representatives from Weil and V&E also attended the meeting. At the meeting, Mr. Ticatch discussed the planned outage of the Partnership's facility to make repairs to a crack in one of the reactors. Mr. Lumpkins then updated the Board of Directors on developments with respect to the Potential Transaction. Representatives from Weil reported to the Board of Directors that negotiations with Parent and its counsel were ongoing and that both sides continued to exchange comments to the merger agreement. Weil informed the Board of Directors that Parent had indicated it would agree to a termination right for a superior proposal during a 30-day "window shop" period but would seek a termination fee of $65.0 million, or approximately 3.75% of the transaction value. Weil also stated that negotiations were ongoing regarding the structure of the transaction and whether a written consent of limited partners holding a majority of the Common Units would be required at the time of execution of the merger agreement. Weil informed the Board of Directors that while Parent's revised draft of the merger agreement contemplated cancellation and delivery of the Phantom Units at signing, Parent indicated that the Partnership should be responsible for half of the costs related to the Phantom Units which effectively decreased the $12.35 per Common Unit offer when full vesting and payout of the Phantom Units was taken into account. After discussion, the Board of Directors instructed Weil to push for a longer "window shop" period and a lower termination fee so as to give the Board of Directors a greater ability to consider alternative proposals from third parties after signing of the merger agreement. Members of the Board of Directors also reviewed the recent trading price of the Common Units and a consensus emerged that the Board of Directors would be uncomfortable with the prospect of announcing a transaction below the then-current trading price of the Common Units. On April 25, 2014, the NYSE closing sale price of the Partnership's Common Units was $13.66 per Common Unit.

        From April 26, 2014 through April 30, 2014, representatives from Parent and the Partnership held discussions and negotiations regarding the Final Distribution.

        Throughout the week of April 28, 2014, Weil and Jones Day exchanged comments to the merger agreement and discussed proposals to address the issues that remained in the merger agreement.

        On April 28, 2014, Messrs. Lumpkins, Hirt and Sementelli held a meeting at V&E's offices in Houston. As a result of the discussions among the parties, Parent offered a package of agreements to resolve the open economic issues among the parties. The package of agreements was: (i) Parent increased its offer price to $12.55 per Common Unit and included all of the Phantom Units granted under the LTIP in the transaction at the same price; (ii) Parent agreed to withdraw its proposals regarding a closing condition regarding the absence of transaction-related litigation and its request for an indemnity agreement from Lindsay Goldberg; and (iii) the parties agreed that approximately $12.0 million would be deducted from the Final Distribution in order to cover a portion of the transaction-related costs of the Partnership.

        Also on April 28, 2014, representatives from Parent and the Partnership held another in-person due diligence meeting at the Houston offices of V&E. The diligence meetings covered facility operations, corporate matters, environmental issues, intellectual property and finance and accounting matters.

        On April 29 and 30, 2014, representatives from Parent and the Partnership held due diligence conference calls to discuss employee benefits, human resources matters and insurance matters.

        On May 1, 2014, the Board of Directors held a telephonic meeting. Representatives from Weil, V&E and MNAT also joined the meeting. At the meeting, Mr. Ticatch provided an update to the Board on the operational issues at the Partnership's facility and stated that the issues were not anticipated to cause any impediment to the Potential Transaction. Members of management updated the Board of Directors on the status of negotiations and discussions with Parent, including the recent increase in the offer price by Parent. Messrs. Lumpkins and Ticatch also discussed and answered questions concerning a plan developed by Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch to address the concerns previously raised by the Board of Directors about the possibility of announcing a transaction at a price at or below the market trading price for the Common Units. Representatives from Lindsay Goldberg explained that Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch would be willing to accept a lower price for their Common Units so that the additional value could be transferred to the unaffiliated Public Unitholders in order to increase the price being offered to those Unitholders to a premium over the then-current trading price of the Common Units. As explained to the Board of Directors by Lindsay Goldberg, the final amount of the transfer was still under consideration, but was likely to be in the amount of approximately $50.0 million. On May 1, 2014, the NYSE closing sale price of the Common Units was $12.61 per Common Unit.

        At the May 1, 2014 Board of Directors meeting, Representatives from Weil also updated the Board of Directors on key developments in its negotiations with Parent and Jones Day. Weil noted that Parent had agreed to a termination right for a superior proposal during a 40-day "window shop" period (an increase over the previous 30-day period offered by Parent) which would allow the Board of Directors to respond to and accept a superior offer from an unaffiliated third party during the 40-day period following the announcement of the Potential Transaction. Weil informed the Board of Directors that Parent agreed to a $57.0 million termination fee (approximately 3.25% of the transaction value) which was a decrease compared to the previous request for a $65.0 million termination fee (approximately 3.75% of the transaction value). Weil also noted that Parent had agreed to pay the Partnership a termination fee of $57.0 million if the Potential Transaction could not close due to certain specified antitrust issues. Weil indicated that negotiations were ongoing regarding employee retention and severance matters. The Board of Directors instructed Weil to continue to negotiate for appropriate employee retention provisions to ensure the Partnership had the necessary personnel to continue operations at its facility.

        During the May 1, 2014 meeting, the Board of Directors also discussed possible plant expansion projects that had been previously reviewed by the Board of Directors and which could be implemented

22


Table of Contents

by the Partnership if it were to continue as a standalone entity, and which had been discussed with Parent in an effort to have Parent further increase its offer price. Members of management noted that the scope, timing and costs of the projects still needed to be developed to determine the feasibility of the projects. Management further noted that some of the projects involved experimental and possibly risky changes to the Partnership's facility. In addition, it was discussed that all of the projects, if undertaken, had execution risk and would require extended outages at the plant which would also entail a number of operational considerations. Mr. Lumpkins confirmed that management had previously disclosed the details of the potential projects with Parent and that management planned to share the presentation regarding possible plant expansion projects that was presented to the Board of Directors with Morgan Stanley and Evercore.

        On May 2, 2014, representatives from Parent and the Partnership also held due diligence conference calls regarding environmental and operational matters.

        On May 3, 2014, Cravath, Swaine & Moore LLP ("Cravath"), which had been engaged by Lindsay Goldberg and York Capital at the end of April 2014 in connection with the support agreements requested by Parent, provided comments to Jones Day to the draft support agreements accepting the requirement to provide a written consent to the transaction upon signing and, in general, the termination fee. From May 3, 2014 to May 27, 2014, Jones Day and Cravath exchanged drafts of the support agreements for Lindsay Goldberg and York Capital and negotiated and finalized these agreements.

        On May 4, 2014, representatives from Parent, Jones Day, the Partnership and Weil held a meeting at the Dallas offices of Jones Day to discuss the current draft of the merger agreement and negotiate the unresolved issues in the agreement.

        On May 5, 2014, the Board of Directors held a meeting at the Houston offices of V&E. Representatives from Weil, V&E, MNAT, Morgan Stanley and Evercore also participated in the meeting. Mr. Ticatch updated the Board of Directors on operational issues and noted that the plant had been taken out of service the previous day to repair a crack in one of the reactors. He informed the Board of Directors that repairs were progressing well and the repair would be permanent. Mr. Ticatch also informed the Board of Directors that management had further discussed the potential plant expansion projects with Parent as a basis for Parent to increase its offer for the Partnership's Common Units, but that Parent was unwilling to further increase its offer price due to the considerable execution risk in the potential expansion plans. Representatives from Weil then updated the Board of Directors on the status of negotiations with Parent and Jones Day. Weil reviewed the progress that had been made with respect to the terms of the merger agreement since the April 8, 2014 Board of Directors meeting. Weil informed the Board of Directors that Lindsay Goldberg and York Capital would execute a written consent on the day the merger agreement is executed, but the Partnership was able to negotiate for a "window shop" provision allowing the Partnership to accept a superior proposal from a third party within 40 days after signing. Weil explained that if the Partnership were to accept a superior proposal during the 40-day period, the written consents of Lindsay Goldberg and York Capital would be nullified. Members of the Board of Directors agreed that the ability of the Partnership to accept a superior proposal was a very favorable development compared to Parent's initial offer, which would not have permitted the Partnership to take such action. Weil also explained the merger agreement's termination provisions and consequences of termination under various scenarios. Weil discussed and answered questions concerning the interim operating covenants and representations and warranties of the Partnership under the merger agreement and stated that significant progress had been made on those fronts as well. Representatives from Weil stated that the most significant open issues in the merger agreement related to employee severance and retention matters. The Board of Directors instructed the Transaction Committee to develop a package of proposals with respect to employee matters.

        Representatives from Morgan Stanley joined the May 5, 2014 meeting and provided a preliminary valuation analysis of the Partnership as well as the Partnership's market performance, dynamics in the propane and propylene industry and the trading volatility of the Common Units. Morgan Stanley also reviewed the Partnership's performance relative to other variable pay master limited partnerships, its unit price performance and analyst perspectives on the Partnership. In reviewing all of the financial analyst ratings and target prices for the Partnership, Morgan Stanley noted that one financial analyst indicated an outlier target price for the Partnership of $17.00 per Common Unit, which may reflect, among other things, an assumed higher capacity utilization rate for our facility than what management forecasts project or that the Partnership's historical plant utilization rate would suggest. Morgan Stanley further reviewed management's forecasts, which indicated that distributions to the Unitholders were forecast to decline over time. Morgan Stanley also reviewed Wall Street consensus estimates for the Partnership for 2014 through 2016. Morgan Stanley then discussed the financial analyses performed and the ranges of values generated by each methodology. Morgan Stanley discussed and answered questions concerning the assumptions underlying the analyses, such as discount rates and multiples. Morgan Stanley also discussed and answered questions concerning the entities and transactions selected by Morgan Stanley for its comparable entities and comparable transaction analyses. Morgan Stanley also discussed a sensitivity analysis performed by Morgan Stanley for both the discounted cash flow analysis and the distribution discount model, with varied assumptions as to the propane-to-propylene pricing spread and the plant capacity utilization rate. Morgan Stanley also reviewed the process in which it had participated in 2013 described above to identify and make contact with certain parties believed to have a potential interest in acquiring some or all of the Partnership's units. Morgan Stanley stated that, while it would be impossible to know without asking whether any of the entities contacted at that time might now have an interest in the Partnership, there was, from Morgan Stanley's perspective, no obvious strategic counterparty that would be likely to have an interest in the Partnership. Representatives from Morgan Stanley stated that they believed the 40-day "window shop" period contemplated by the Partnership and Parent would be adequate time for potential acquirors to review the Partnership's business and make a bid if they so desired.

        After the representatives of Morgan Stanley left the May 5, 2014 meeting, representatives from Evercore joined the meeting and made a separate presentation to the Board of Directors.

        Evercore reviewed the proposed terms of the Potential Transaction and discussed its preliminary financial analysis of the Potential Transaction. Additionally, Evercore discussed and answered questions from the members of the Board of Directors regarding Evercore's preliminary financial analysis surrounding dynamics in the propane and propylene markets, the Partnership's market performance and trading history, discounted cash flow analysis, comparable transactions, third party crude oil and natural gas price forecasts and the potential impact of such price forecasts on expected propylene production. Evercore also discussed the IHS Inc. ("IHS") forecasted propylene supply versus demand, and IHS's forecast that additional announced propane dehydrogenation facility capacity is expected to be built by competitors in the industry by 2018, which could imply a decrease in future propylene pricing assuming all facilities are constructed, although somewhat countered by IHS's forecasted increase in future demand. Additionally, Evercore discussed the propane-to-propylene pricing spread, which Evercore noted is a significant driver of the Partnership's ability to generate free cash flow and noted that one industry forecast provided by management suggests that the propane-to-propylene spread will continue to decrease over time. Evercore also discussed and answered questions concerning the valuation ranges generated under each of its valuation methodologies utilizing management's base case projections and upside and downside sensitivity cases it had prepared. Evercore then reviewed the analysis and assumptions it used for each of the valuation methodologies.

        Following the discussions with Morgan Stanley and Evercore at the May 5, 2014 meeting, the Board of Directors engaged in a discussion regarding the Potential Transaction and the proposal that Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch transfer a portion of the value to be received by them in the Potential Transaction to the Public Unitholders. Representatives from Lindsay Goldberg informed the Board of Directors that Lindsay Goldberg had no need for liquidity in the fund that holds Lindsay Goldberg's investment in the Partnership and that Lindsay Goldberg's principals' interests were aligned with those of other Unitholders. Representatives from Lindsay Goldberg further stated that they believed Parent was providing a good valuation for the Partnership in the Potential Transaction and that Lindsay Goldberg's decision to transfer value to the Public Unitholders was in order to serve the best interests of all Unitholders so that Public Unitholders could realize a potential premium over the current trading price of the Common Units. Representatives from York Capital stated that they also did not have a need for liquidity and that York Capital's investment in the Partnership was held in a long-term fund with several years remaining. York Capital also stated that it viewed the price proposed by Parent to be a good value, particularly considering the new plant capacity that is expected to come online over the next several years, the single asset risk that the Partnership currently has, and the likelihood that the downside risk going forward is greater than the upside potential.

        During the May 5, 2014 Board of Directors meeting, the representatives from Lindsay Goldberg also confirmed that the proposed transfer of value to the Public Unitholders would have no impact on the Unitholders' receipt of the Final Distribution. The independent members of the Board of Directors also expressed their views regarding the Potential Transaction and stated that they believed that Lindsay Goldberg and York Capital viewed the Potential Transaction as being in the best interests of the Public Unitholders and were not motivated by a need for liquidity in their respective funds. The Board of Directors also discussed the fact that the Partnership continues to have significant risk given its single asset and potential industry challenges and the Potential Transaction provided an opportunity to mitigate these risks for the Public Unitholders.

        On May 6, 2014, representatives from Parent and the Partnership held due diligence conference calls to discuss operational matters.

abreast of the status of repairs. It was also noted that while Parent concurred with the steps the Partnership was taking to remedy the operational issues, its desire was not to execute the merger agreement until repairs were completed and certified by outside advisors. Representatives from Weil made a presentation to the Transaction Committee concerning the merger agreement and provided a full review of the merger agreement. Representatives from Weil also discussed the support agreements to be entered into between Parent and Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch, respectively.

        On May 22, 2014, the Board of Directors held a telephonic meeting. Representatives from Weil and V&E also participated in the meeting. Mr. Ticatch updated the Board of Directors with respect to repairs of a crack in one of the plant's reactors and noted that the repair had been completed and was deemed to be permanent. Mr. Ticatch further noted that Parent had been kept updated throughout the repair process and was satisfied with the outcome. Mr. Lumpkins informed the Board of Directors that Parent's due diligence in connection with the Potential Transaction was nearly complete. Representatives from Weil updated the Board of Directors on the status of negotiations with Parent and Jones Day, and stated that the terms of the merger agreement were nearly final. Weil reviewed the key provisions of the merger agreement including termination provisions, the "window shop" and non-solicitation provisions, the interim operating covenants and the mechanics for the Final Distribution. Weil also discussed the support agreements to be entered into between Parent and Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch, respectively.

        During the May 22, 2014 meeting, the Board of Directors also discussed the one-time value transfer to the Public Unitholders that had been agreed to by Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch. A representative from Lindsay Goldberg stated that while the Potential Transaction contemplated a purchase price of $12.55 per Common Unit, the value transfer would result in a price of $14.00 per Common Unit for the Public Unitholders and $12.00 per Common Unit for Lindsay Goldberg, York Capital and Messrs. Lumpkins and Ticatch. Representatives from Lindsay Goldberg noted that, in addition to the anticipated cash distributions, the value transfer would result in a modest premium being paid to the Public Unitholders and a slightly larger premium based on longer-term trading prices. Mr. Ticatch noted that in his view the value transfer was appropriate and in the best interests of the Public Unitholders. The Board of Directors then discussed the value transfer in greater detail. In addition, the Board of Directors agreed that the Potential Transaction was in the best interests of the Unitholders. Messrs. Lumpkins and Ticatch confirmed to the Board of Directors that

they had no discussions concerning their employment, if any, with the Partnership post-closing in the event that the Board of Directors approves the Potential Transaction.

        From May 22, 2014 to May 26, 2014, Weil and Jones Day exchanged comments to the merger agreement and discussed and negotiated proposals with respect to items that remained unresolved in the merger agreement. Representatives from Parent and the Partnership also continued to discuss and exchange drafts of the merger agreement provisions relating to the Final Distribution.

        Also on May 22, 2014, Bracewell & Giuliani LLP ("B&G"), which had been recently engaged to represent Messrs. Lumpkins and Ticatch in connection with their proposed support agreements, provided Weil with comments to the Jones Day drafts of such support agreements, and Weil subsequently forwarded those comments to Jones Day. From May 23, 2014 to May 27, 2014, Jones Day and B&G exchanged drafts of the support agreements for Mr. Lumpkins and a related family partnership and for Mr. Ticatch and a related family trust, and negotiated and finalized these agreements with the assistance of Weil.

        On May 27, 2014, the Board of Directors held a meeting at the Houston offices of V&E. Representatives from Weil, V&E, MNAT, Morgan Stanley and Evercore also participated in the meeting. Representatives from Weil reported that all issues in the merger agreement and ancillary agreements, including the merger agreement provisions relating to the Final Distribution, had been resolved. A representative from Weil then presented a detailed summary of the merger agreement and its provisions to the Board of Directors. Representatives from Morgan Stanley and Evercore discussed separately with the Board of Directors their respective financial analyses of the Potential Transaction.

        Representatives of Evercore stated that their financial analyses were similar to the analyses reviewed in detail with the Board of Directors during its meeting on May 5, 2014. Evercore discussed and answered questions from the members of the Board of Directors regarding their financial analysis. Evercore also discussed and answered questions from the members of the Board of Directors regarding Evercore's financial analysis surrounding dynamics in the propane and propylene markets, the Partnership's market performance and trading history, discounted cash flow analysis, comparable transactions, third party crude oil and natural gas price forecasts and the potential impact of such price forecasts on expected propylene production. Additionally, Evercore discussed the propane-to-propylene pricing spread, which Evercore noted is a significant driver of the Partnership's ability to generate free cash flow and noted that one industry forecast provided by management suggests that the propane-to-propylene spread will continue to decrease over time. Evercore also discussed and answered questions concerning the valuation ranges generated under each of its valuation methodologies utilizing management's projections and certain upside and downside sensitivity analyses that Evercore had prepared. Evercore also reviewed the analysis and assumptions it used for each of the valuation methodologies. In response to a question concerning one analyst price target for the Partnership that exceeded the price being offered by Parent, representatives of Evercore stated that price targets can be driven by many factors which can vary materially between various analysts, including yield expectations. Finally, in response to questions, representatives of Evercore indicated that the $57.0 million termination fee represents a percentage of the transaction value that is representative of historical transactions and that 40 days would be an adequate period of time post-signing for potentially interested buyers, if any, to investigate the Partnership and submit a potentially superior proposal. At the conclusion of Evercore's presentation, Evercore orally delivered its opinion, which was subsequently confirmed in writing, that, as of May 27, 2014 and subject to the limitations and qualifications as more fully described below in the section entitled "—Opinions of our Financial Advisors—Opinion of Evercore," the Public Merger Consideration was fair, from a financial point of view, to the Public Unitholders.

        Representatives of Morgan Stanley then joined the May 27, 2014 Board of Directors meeting. The representatives of Morgan Stanley stated that their financial analyses were similar to the analyses

reviewed in detail with the Board of Directors during its meeting on May 5, 2014. Morgan Stanley discussed and answered questions concerning the Partnership's historical unit price performance over various intervals, including the premium implied by the $14.00 per unit price offered to the price of Common Units. Morgan Stanley noted that the $14.00 per Common Unit price offered in the Potential Transaction exceeds any closing price per Common Unit, on a distribution adjusted basis, since early 2013. A representative from Morgan Stanley then reviewed each of the financial analyses prepared by Morgan Stanley, including the key assumptions underlying each analysis and minor changes to the prior assumptions utilized by Morgan Stanley in certain analyses. Morgan Stanley noted that the discounted cash flow and distribution discount model were important indicators of value because they take into account a longer term set of financial forecasts, which account for the longer term trends in the propane to propylene spread that are forecasted for the industry and the resulting impact on the Partnership in future years. Morgan Stanley stated that no precedent transaction for a master limited partnership is comparable to the Potential Transaction and that it did not place significant weight on the results of its precedent transactions analysis in arriving at its fairness opinion. Finally, the representatives of Morgan Stanley stated that it did not believe that the structure of the Potential Transaction would preclude superior bids for the Partnership from emerging post-signing, should any other potential buyer be interested. At the conclusion of Morgan Stanley's discussion, Morgan Stanley orally delivered its opinion, which was subsequently confirmed in writing, that, as of May 27, 2014 and subject to the limitations and qualifications as more fully described below in the section entitled "—Opinions of Our Financial Advisors—Opinion of Morgan Stanley," the Public Merger Consideration to be received by the Public Unitholders pursuant to the Merger Agreement was fair from a financial point of view to the Public Unitholders.

        The Board of Directors then engaged in a discussion regarding the information presented by Evercore and Morgan Stanley. Members of the Board of Directors noted that the valuation offered by Parent is significantly above the range of the discounted cash flow analysis. The Board of Directors also noted that the premiums paid analysis prepared by Morgan Stanley indicated prices above the $14.00 per Common Unit price being offered by Parent, but a consensus emerged that a comparable transactions analysis was less helpful in evaluating the Potential Transaction because there are no comparable transactions in which a variable pay master limited partnership was acquired for all cash and, therefore, a discounted cash flow analysis was a more useful analysis under the circumstances. The Board of Directors then reviewed the trading price of the Common Units since the Partnership's initial public offering. The Board of Directors then engaged in a discussion as to whether now is the right time to sell the Partnership. The Board of Directors also discussed the changes that had occurred in the propane and propylene industries since the Partnership's initial public offering. Members of the Board of Directors then noted that the historical performance of the utilization of our facility had been below 90% of capacity utilization that is assumed in management's financial projections. The Board of Directors also engaged in a discussion regarding the dynamics in the propane and propylene industries, the future risks of the Partnership given its single asset and emerging competitors. The Board of Directors also discussed that, with the cash distributions at closing, any Public Unitholders who purchased at the $17.00 IPO price and continued to hold their Common Units would likely be made whole and that, for the vast majority of the Public Unitholders who purchased at prices below $14.00 per Common Unit, they will realize a premium on their investment. Each of the independent members of the Board of Directors also affirmed his or her belief that Lindsay Goldberg and York Capital are not motivated to approve the Potential Transaction by any liquidity needs or other interests inconsistent with those of the other Unitholders.

        Following discussion, the Board of Directors determined that given the future risks facing the Partnership, the Potential Transaction represented a very good opportunity for the Unitholders. Mr. Ticatch stated that he was now comfortable with the value being offered to the Public Unitholders and believed the Potential Transaction was in the best interests of the Public Unitholders. Each of the other members of the Board of Directors affirmed that he or she was comfortable with the value

offered in the Potential Transaction, and stated his or her belief that the Potential Transaction represented the best alternative available to the Public Unitholders. Mr. Hirt stated that the Transaction Committee unanimously recommended that the Board of Directors approve the Potential Transaction and believed it was in the best interests of the Public Unitholders. Each of the other members of the Transaction Committee—Messrs. Lumpkins, Ticatch and Ms. Buehl-Reichard—then affirmed that they were in agreement with Mr. Hirt's statement regarding the recommendations of the Transaction Committee. Mr. Lumpkins then held a roll call vote and each director affirmatively voted in favor of the Potential Transaction, and no director voted against the Potential Transaction. The Board of Directors then adopted resolutions which, among other things, declared the merger agreement and the merger and other transactions contemplated by the merger agreement to be advisable and in the best interests of the Partnership, our general partner and Unitholders, authorized our general partner to consent to and approve the merger agreement and the merger and other transactions contemplated by the merger agreement, directed the merger agreement be submitted to the limited partners for approval by written consent without a meeting and recommended that the limited partners approve the merger agreement and the merger and other transactions contemplated in the merger agreement.

        Later in the evening of May 27, 2014, Parent and the Partnership executed the merger agreement. At 5:30 a.m. Central Time on May 28, 2014, the Parent and the Partnership issued a joint press release announcing the transaction.

Recommendation of the Board of Directors

        At a special meeting held on May 27, 2014, after consideration, the Board of Directors, among other things:

Required Approval of the Merger; Written Consent

        Under our Partnership Agreement, the approval of the Board of Directors, along with the affirmative vote or written consent of the holders of a majority of our Common Units outstanding and entitled to vote, is required to approve the Merger Agreement. On May 27, 2014, in accordance with our Partnership Agreement and the recommendation of the Board of Directors, and consistent with applicable Delaware law, the Principal Unitholders, which collectively owned Common Units representing 72.9% of the total number of Common Units then outstanding, delivered a written consent approving the Merger Agreement and the Transactions. Such written consent constituted approval of the Merger Agreement by the holders of the requisite Common Units of the Partnership in accordance with our Partnership Agreement. This means that the Transactions can occur without the vote of any other Unitholders. There will not be a meeting of Unitholders at which you will be asked to vote to approve the Merger Agreement.

        Federal securities laws provide that the Merger may not be consummated until 20 days after the date of mailing of this information statement to our Unitholders. In addition, the Merger Agreement provides the closing may not occur prior to the end of the Unitholder Consent Period. Notwithstanding the execution and delivery of the written consent, the Merger will not occur until these time periods have elapsed and all other conditions to closing related to any regulatory requirements are satisfied. We expect the Merger to be consummated before November 27, 2014; however, there can be no assurance that the Merger will be consummated at that time, or at all.

        The foregoing discussion of the information and factors considered by the Board of Directors is not intended to be exhaustive, but includes the material factors considered by the Board of Directors. In view of the complexity and wide variety of factors considered, the Board of Directors did not find it useful to and did not attempt to quantify, rank or otherwise assign weights to these factors. In addition, the Board of Directors did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to its ultimate determination, but rather the Board of Directors conducted an overall analysis of the factors described above, including discussions with our management and its legal advisors. In considering the factors described above, individual members of the Board of Directors may have given different weights to different factors.

        After considering these factors, the Board of Directors concluded that the positive factors relating to the Merger Agreement and the Merger outweighed the potential negative factors and declared the advisability of the Merger Agreement and the Merger and other Transactions based upon the totality of the information presented to and considered by it.

        Morgan Stanley was retained by the Board of Directors, and its role in connection with the Merger has been limited to providing a financial opinion letter to the Board of Directors in connection with the Merger. Under the terms of Morgan Stanley's engagement letter with the Partnership, Morgan Stanley's role prior to the execution of the Merger Agreement has not included advising on or negotiating the terms of the Merger Agreement. Furthermore, as requested by the Board of Directors, after the announcement of the Merger, Morgan Stanley will (i) act as financial advisor, and assist the Board of Directors, in evaluating any unsolicited proposal with respect to an alternative transaction and (ii) help the Board of Directors determine whether any unsolicited proposal constitutes a superior proposal.

        The following is a brief summary of the material analyses performed by Morgan Stanley in connection with its oral opinion and the preparation of its written opinion dated May 27, 2014. In connection with arriving at its opinion, Morgan Stanley considered all of its analyses as a whole and did not attribute any particular weight to any analysis described below. Considering any portion of such analyses and factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Morgan Stanley's opinion. This summary of financial analyses includes information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The analyses listed in the tables and described below must be considered as a whole; considering any portion of such analyses and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Morgan Stanley's opinion.

        Morgan Stanley reviewed the historical trading range of the Common Units for the 52-week period ending May 23, 2014, which was the last trading day immediately preceding the date that Morgan Stanley gave its presentation to the Board of Directors. Morgan Stanley noted that, during such period, the range of lowest to highest intraday trading prices of the Common Units was $10.37 to $14.20 per Common Unit.

        Morgan Stanley also calculated the adjusted unit price of the Common Units for the 52-week period ending May 23, 2014, which was the last trading day immediately preceding the date that Morgan Stanley gave its presentation to the Board of Directors, by adjusting the price per Common Unit for distributions paid during the time period. Morgan Stanley noted that, during such period, the range of lowest to highest adjusted intraday prices of the Common Units was $9.70 to $13.83 per Common Unit.

        Morgan Stanley additionally reviewed the historical volume weighted average prices and adjusted prices and calculated the percentage premium of the Public Merger Consideration to those prices. The following table indicates the volume weighted average prices and adjusted prices and percentage premium of the Public Merger Consideration implied for 30-day, 60-day and 90-day time periods:

        Morgan Stanley reviewed and analyzed the public market trading price targets for the Common Units prepared and most recently published by equity research analysts as of May 23, 2014. These targets reflect each analyst's estimate of the 12-month forward public trading price of the Common Units. Morgan Stanley noted that such analyst price targets for the Common Units ranged from $12.00 to $17.00 per Common Unit. Morgan Stanley calculated the current unit price implied by the analysts' 12-month forward price targets for the Common Units by discounting the price targets by one year at a rate of 9.5%, based on Morgan Stanley's calculation of the Partnership's cost of equity. Morgan Stanley noted that the implied unit price of the equity research analysts on this basis ranged from $10.96 to $15.53 per Common Unit.

        The public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the Common Units and these estimates are subject to uncertainties, including the future financial performance of the Partnership and future financial market conditions.

        Morgan Stanley performed a discounted cash flow analysis, which is designed to provide the implied value of the Partnership by calculating the present value of estimated future cash flows. Morgan Stanley calculated a range of implied unit prices for the Partnership, based on estimates of future cash flows contained in management estimates for the calendar years 2014 through 2018.

        Morgan Stanley first calculated the unlevered free cash flow of the Partnership for the period from July 1, 2014 to December 31, 2017. Morgan Stanley calculated a terminal value for the Partnership by applying a range of aggregate value to next-twelve-month EBITDA multiples of 6.5x to 8.5x to the management estimate of 2018 EBITDA. Morgan Stanley discounted the unlevered free cash flows and terminal value to a present value as of June 30, 2014 using a range of discount rates from 8.0 to 10.0%, which range was selected by Morgan Stanley based on Morgan Stanley's estimate of the Partnership's weighted average cost of capital.

        Based on the calculations described above, this analysis indicated a range of implied unit prices from $8.96 to $11.85 per Common Unit.

        Morgan Stanley performed a discounted distribution model analysis, which is designed to provide the implied value of a Common Unit by calculating the present value of the estimated distributions to Unitholders. Morgan Stanley calculated a range of implied unit prices for the Partnership, based on estimates of distributions per Common Unit contained in management estimates for the calendar years 2014 through 2018.

        Morgan Stanley noted the estimated distributions per Common Unit for the period from July 1, 2014 to December 31, 2017. Morgan Stanley calculated a terminal value for a Common Unit by applying a range of forward yields of 11.0% to 13.0% to the management estimate of the 2018 distribution per Common Unit. The distributions and the terminal value were then discounted to present values as of June 30, 2014 using a range of discount rates from 8.5% to 10.5%, based on Morgan Stanley's estimate of the Partnership's then current cost of equity. Based on management estimates of Partnership distributions per Common Unit, this analysis indicated a range of implied prices from $9.86 to $11.51 per Common Unit.

        Morgan Stanley reviewed with our management the estimated cost of replacing the Partnership's plant, which was estimated by management to be in the range of $1.2 billion to $1.3 billion. Morgan Stanley used this estimate of replacement value to estimate implied Common Unit prices. This analysis resulted in implied prices ranging from $5.97 to $6.68 per Common Unit.

        Morgan Stanley performed a comparable trading analysis, which is designed to provide an implied value of the Partnership by comparing it to similar partnerships and corporations that are publicly traded. In performing this analysis, Morgan Stanley reviewed and compared certain financial information of the Partnership with publicly available information for selected (i) variable pay master limited partnerships ("Master LPs") with publicly traded equity securities and (ii) chemical companies ("Chemical Companies") with publicly traded equity securities.

        The selected entities were chosen because they are companies with publicly traded equity securities and were deemed to be similar to the Partnership, in one or more respects including the nature of their business, corporate structure, cash flow profile, size, diversification, financial performance and geographic concentration. No specific numeric or other similar criteria were used to choose the selected entities and all criteria were evaluated in their entirety without application of definitive qualifications or limitations to individual criteria. As a result, a significantly larger or smaller partnership or corporation with substantially similar lines of businesses and business focus may have been included while a similarly sized partnership or corporation with less similar lines of business and greater diversification may have been excluded. Morgan Stanley identified and included a sufficient number of partnerships and corporations for the purposes of its analysis but may not have included all partnerships and corporations that might be deemed comparable to the Partnership.

        The Master LPs with publicly traded equity securities selected for the comparable trading analysis were:

        The financial data for the Partnership used in the analysis was based on (i) management forecasts ("Management Forecasts") and (ii) estimates from equity research analysts ("Consensus Estimates").

        Morgan Stanley applied ranges of multiples and yields based on the comparable data for the Master LPs to corresponding financial data for the Partnership, based on Management Forecasts and Consensus Estimates data for the Partnership, to calculate an implied unit price range.

        Calendar Year 2014.    Morgan Stanley applied multiples ranging from 6.5x to 8.5x, based on the ratio of aggregate value to calendar year 2014 EBITDA of the comparable Master LPs, to the corresponding calendar year 2014 EBITDA for the Partnership to calculate an implied unit price range for the Partnership. Based on Management Forecasts, this analysis indicated an implied unit price range of $10.28 to $14.24 per Common Unit. Based on Consensus Estimates data, this analysis indicated an implied price range of $9.91 to $13.76 per Common Unit.

        Morgan Stanley applied yield rates ranging from 11.0% to 13.0%, based on the calendar year 2014 yields of comparable Master LPs, to the corresponding calendar year 2014 distribution per Common Unit for the Partnership to calculate an implied unit price range for the Partnership. Based on Management Forecasts, this analysis indicated an implied unit price range of $11.85 to $14.00 per Common Unit. Based on Consensus Estimates data, this analysis indicated an implied price range of $11.00 to $13.00 per Common Unit.

        Calendar Year 2015.    Morgan Stanley applied multiples ranging from 6.0x to 8.0x ,based on the ratio of aggregate value to calendar year 2015 EBITDA of the comparable Master LPs, to the corresponding calendar year 2015 EBITDA for the Partnership to calculate an implied unit price range for the Partnership. Based on Management Forecasts, this analysis indicated an implied unit price range of $9.60 to $13.67 per Common Unit. Based on Consensus Estimates, this analysis indicated an implied price range of $9.28 to $13.24 per Common Unit.

        Morgan Stanley applied yield rates ranging from 11.0% to 13.0%, based on the calendar year 2015 yields of comparable Master LPs, to the corresponding calendar year 2015 distribution per Common Unit for the Partnership to calculate an implied unit price range for the Partnership. Based on Management Forecasts, this analysis indicated an implied unit price range of $11.92 to $14.09 per Common Unit. Based on Consensus Estimates, this analysis indicated an implied price range of $11.00 to $13.00 per Common Unit.

In evaluating the comparable partnerships and corporations, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of the Partnership, such as the impact of competition on the business of the Partnership or the industry generally, industry growth and the absence of any adverse material change in the financial condition of the Partnership or the industry or in the financial markets in general, which could affect the public trading value of the partnerships or corporations. Mathematical analysis (such as determining the median, high or low) is not a meaningful method of using comparable partnership and corporation data.

        Morgan Stanley calculated implied unit price ranges by applying various multiples of transaction value based on the purchase prices and premiums paid in selected publicly announced merger transactions that it deemed relevant to financial data for the Partnership.

        Morgan Stanley calculated implied unit price ranges by applying a range of purchase price premiums based on the purchase prices and exchange ratios in selected publicly announced merger transactions where the target company was a master limited partnership that it deemed relevant (the "Selected MLP Transactions") to the financial data for the Partnership.

        The selected merger transactions were chosen because the mergers were deemed to be similar to the Merger in one or more respects, including the nature of their business, corporate structure, cash flow profile, size, diversification, financial performance and geographic concentration. No specific numeric or other similar criteria were used to choose the selected transactions and all criteria were evaluated in their entirety without application of definitive qualifications or limitations to individual criteria. As a result, a transaction involving the acquisition of a significantly larger or smaller company with substantially similar lines of businesses and business focus may have been included while a transaction involving the acquisition of a similarly sized company with less similar lines of business and greater diversification may have been excluded. Morgan Stanley identified a sufficient number of

        Morgan Stanley calculated the premium to historical trading relationship in the Selected MLP Transactions based on the offered exchange ratio and consideration (as applicable) relative to the unaffected trading exchange ratio or unit price for each respective transaction one-day prior to the announcement of the transaction and on May 23, 2014 with respect to the Merger. This analysis indicated the following:

 
  Low   High   Median   Mean  

Premium to Relative Trading One Day Prior

    2.2 %   21.2 %   14.5 %   13.7 %

        Morgan Stanley applied the premium of each of the Selected MLP Transaction analysis to the Common Unit price as of May 23, 2014 to calculate implied unit prices. The implied prices ranged from $13.24 to $15.70 per Common Unit based on premiums to one day prior relative trading with respect to the Selected MLP Transactions.

        In addition, Morgan Stanley calculated multiples based on the ratio of aggregate value to EBITDA of certain other selected publicly announced merger transactions in the petrochemical and commodity chemicals industries that it deemed relevant (the "Selected Chemical Industry Transactions").

        The selected merger transactions were chosen because the mergers were deemed to be similar to the Merger in one or more respects, including the nature of their business, size, diversification, financial performance and geographic concentration. No specific numeric or other similar criteria were used to choose the selected transactions and all criteria were evaluated in their entirety without application of definitive qualifications or limitations to individual criteria. As a result, a transaction involving the acquisition of a significantly larger or smaller company with substantially similar lines of businesses and business focus may have been included while a transaction involving the acquisition of a similarly sized company with less similar lines of business and greater diversification may have been excluded.

        For the Selected Chemical Industry Transactions, Morgan Stanley calculated multiples based on the ratio of aggregate value to EBITDA. The financial data reviewed included the ratio of aggregate value (calculated as of one day prior to the announcement for the selected transactions) to last twelve month ("LTM") EBITDA (calculated as EBITDA for the four most recent report fiscal quarters prior to the selected transaction announcement). The analysis indicated the following low, high and median values for the Selected Chemical Industry Transactions:

 
  AV / LTM EBITDA  
Description
  Low   High   Median  

Selected Chemical Industry Transactions

    5.0x     7.5x     5.4x  

        Due to the business variability of the Partnership, Morgan Stanley considered there to be two corresponding metrics to the multiples of aggregate value to EBITDA for the selected precedent transactions: LTM EBITDA (calculated as EBITDA for the four most recently reported fiscal quarters prior to the transaction announcement) and Annualized Q1 2014 EBITDA (calculated as four times the reported EBITDA for the Partnership for the quarter ended March 31, 2014, the most recent reported fiscal quarter prior to the announcement of the Merger).

        Based on the analysis of precedent transactions and its professional judgment, Morgan Stanley selected a reference range of Aggregate Value to EBITDA of 5.0x to 7.0x. Using LTM EBITDA, this analysis indicated an implied price range of $4.67 to $7.58 per Common Unit. Using Annualized Q1 2014 EBITDA, this analysis indicated an implied price range of $7.04 to $10.90 per Common Unit.

        The table below reflects the results of this analysis:

        No company or transaction utilized in the precedent transactions analysis is identical to the Partnership, Parent, or the Merger. In evaluating the precedent transactions, Morgan Stanley made judgments and assumptions with regard to general business, market and financial conditions and other matters, which are beyond the control of the Partnership, such as the impact of competition on the business of the Partnership or the industry generally, industry growth and the absence of any adverse material change in the financial condition of the Partnership or the industry or in the financial markets in general, which could affect the public trading value of the companies and the aggregate value of the transactions to which they are being compared.

        In connection with the review of the Merger by the Board of Directors, Morgan Stanley performed a variety of financial and comparative analyses and reviewed such underlying data as Morgan Stanley deemed relevant for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Furthermore, Morgan Stanley believes that the summary provided and the analyses described above must be considered as a whole and that selecting any portion of the analyses, without considering all of the analyses as a whole, would

42


Table of Contents

create an incomplete view of the process underlying Morgan Stanley's analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described above should not be taken to be the view of Morgan Stanley with respect to the actual value of the Partnership. In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business, regulatory, economic, market and financial conditions and other matters. Many of these assumptions are beyond the control of the Partnership. Any estimates contained in Morgan Stanley's analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

        Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness of the Public Merger Consideration pursuant to the Merger Agreement from a financial point of view to the Public Unitholders as of the date of and in connection with the delivery of its opinion to the Board of Directors. These analyses do not purport to be appraisals or to reflect the prices at which the Common Units might actually trade.

        Morgan Stanley's opinion and its presentation to the Board of Directors was one of many factors taken into consideration by the Board of Directors in deciding to approve and recommend that the Board of Directors authorize the execution of the Merger Agreement and the related documents and the Transactions. Consequently, the analyses as described above should not be viewed as determinative of the opinion of the Board of Directors with respect to the Public Merger Consideration or of whether the Board of Directors would have been willing to agree to a different amount. Morgan Stanley did not recommend any specific merger consideration to the Board of Directors or that any specific merger consideration constituted the only appropriate merger consideration for the Merger.

        Morgan Stanley's opinion was approved by a committee of Morgan Stanley investment banking and other professionals in accordance with its customary practice.

        Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Its securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect transactions, for their own account or the accounts of its customers, in debt or equity securities or loans of the Partnership, Parent or any other company, or any currency or commodity, that may be involved in the Transactions, or any related derivative instrument. In the two years prior to the date of Morgan Stanley's opinion, Morgan Stanley provided financial advisory and financing services for the Partnership, Lindsay Goldberg and its affiliates and Parent and its affiliates and has received fees in connection with such services. Morgan Stanley may also seek to provide such services to the Partnership, Lindsay Goldberg or its affiliates or Parent or its affiliates in the future and expects to receive fees for the rendering of these services.

        Under the terms of its engagement letter with the Board of Directors, Morgan Stanley provided the Board of Directors a financial opinion letter in connection with the Merger. Under the Engagement Letter, Morgan Stanley will be paid a fee of $2.0 million for rendering the financial opinion, and Morgan Stanley will be paid an additional fee of $5.5 million contingent on completion of the Merger. The Partnership has also agreed to reimburse Morgan Stanley for its expenses incurred in performing its services. In addition, the Partnership has agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities

under the federal securities laws, related to or arising out of Morgan Stanley's engagement. Since 2011, Morgan Stanley has provided financial advisory and other services to the Partnership, Lindsay Goldberg and its affiliates and Parent and its affiliates, which has resulted in Morgan Stanley receiving in excess of $25.0 million in compensation from the Partnership, in excess of $10.0 million in compensation from Lindsay Goldberg and its affiliates and approximately $9.0 million in compensation from Parent and its affiliates.

        On May 27, 2014, Evercore delivered its oral opinion to the Board of Directors, which opinion was subsequently confirmed by delivery of a written opinion dated May 27, 2014, to the effect that, as of such date and based upon and subject to assumptions made, matters considered and limitations on the scope of review undertaken by Evercore as set forth in its opinion, the Public Merger Consideration was fair, from a financial point of view, to the Public Unitholders.

        The full text of the written opinion of Evercore, dated May 27, 2014, which sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review undertaken in rendering its opinion, is included as Annex D to this information statement.

Table of Contents

        For purposes of its analysis and opinion, Evercore assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available and all of the information supplied or otherwise made available to, discussed with, or reviewed by Evercore, and Evercore assumes no liability therefor. With respect to the projected financial and operating data relating to the Partnership, Evercore assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Partnership as to the future financial performance of the Partnership under the assumptions stated therein. Evercore expressed no view as to the projected financial and operating data relating to the Partnership or any judgments, estimates or assumptions on which they are based. Evercore relied, at the Partnership's direction, without independent verification, upon the assessments of the management of the Partnership as to the future financial and operating performance of the Partnership.

        For purposes of rendering its opinion, Evercore assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the Merger Agreement (in the draft form reviewed by Evercore) are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement and that all conditions to the consummation of the Merger will be satisfied without material waiver or modification thereof. Evercore further assumed that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Merger will be obtained without any material delay, limitation, restriction or condition that would have an adverse effect on the Partnership or the consummation of the Merger or materially reduce the benefits of the Merger to the Public Unitholders. Evercore has assumed the final versions of all documents reviewed by Evercore in draft form conform in all material respects to the drafts reviewed by Evercore.

        Evercore did not make, nor did it assume any responsibility for making, any independent valuation or appraisal of the assets or liabilities of the Partnership, nor was Evercore furnished with any such appraisals, nor did Evercore evaluate the solvency or fair value of the Partnership under any state or federal laws relating to bankruptcy, insolvency or similar matters. Evercore's opinion was necessarily based upon information made available to Evercore as of the date of the opinion and financial, economic, monetary, market, regulatory and other conditions and circumstances as they existed and as could be evaluated on the date of the opinion. It is understood that subsequent developments may affect Evercore's opinion and that Evercore does not have any obligation to update, revise or reaffirm the opinion.

        Evercore was not asked to pass upon, and expressed no opinion with respect to, any matter other than the fairness of the Public Merger Consideration, from a financial point of view, as of the date of its opinion, to the Public Unitholders. Evercore did not express any view on, and its opinion does not address, the fairness of the Merger to, or any consideration received in connection therewith by, the Principal Unitholders or the holders of any other securities, or any creditors or other constituencies, of the Partnership, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Partnership or any of the other parties to the Merger Agreement, or any class of such persons, whether relative to the Public Merger Consideration or otherwise. Evercore assumed that any modification to the structure of the Merger would not vary in any respect material to its analysis. Evercore's opinion did not address the relative merits of the Merger as compared to other business or financial strategies that might be available to the Partnership, nor did it address the underlying business decision of the Partnership to engage in the Merger. In arriving at its opinion, Evercore was not authorized to solicit, and did not solicit, interest

from any third party with respect to the acquisition of any or all of the Common Units or any business combination or other extraordinary transaction involving the Partnership. Evercore's opinion letter, and Evercore's opinion, did not constitute a recommendation to the Board of Directors or to any other persons in respect of the Merger, including as to how to vote or act in respect of the Merger. Evercore expressed no opinion as to the price at which the Common Units will trade at any time. Evercore is not a legal, regulatory, accounting or tax expert and assumed the accuracy and completeness of assessments by the management of the Partnership and their advisors with respect to legal, regulatory, accounting and tax matters.

        Except as described above, the Board of Directors imposed no other restrictions or limitations on Evercore with respect to the investigations made or the procedures followed by Evercore in rendering its opinion. Evercore's opinion was only one of many factors considered by the Board of Directors in its evaluation of the Merger and should not be viewed as determinative of the views of the Board of Directors with respect to the Merger or the Merger Consideration. Set forth below is a summary of the material financial analyses reviewed by Evercore on May 27, 2014 in connection with rendering its opinion. The following summary, however, does not purport to be a complete description of the analyses performed by Evercore. The order of the analyses described and the results of these analyses do not represent relative importance or weight given to these analyses by Evercore. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data that existed on or before May 27, 2014, and is not necessarily indicative of current market conditions.

        The acquisition of each outstanding Common Unit owned by the Public Unitholders as proposed in the Merger Agreement provides for the conversion of each outstanding Common Unit owned by the Public Unitholders into the right to receive $14.00 in cash.

        Evercore performed a series of analyses to derive an indicative valuation range for the Common Units and compared each one of the resulting implied value ranges per Common Unit to the Public Merger Consideration.

        Evercore performed a discounted cash flow analysis of the Partnership to derive an implied per unit value range for the Common Units based on the present value of (i) the projected cash flows of the Partnership and (ii) the projected standalone distributions to be received by the Unitholders, utilizing the projected financial information provided by the management of the Partnership and described in "—Certain Unaudited Projected Financial Information Concerning the Partnership" below.

        With respect to projected cash flows of the Partnership, Evercore calculated the implied per unit value range for the Common Units by utilizing a range of discount rates with a mid-point equal to the Partnership's weighted average cost of capital, as estimated by Evercore based on the capital asset pricing model ("CAPM"), the projected unlevered free cash flows for the six months ended December 31, 2014 and the calendar years 2015 through 2018, and terminal values as of December 31, 2018, based on a range of EBITDA exit multiples as well as perpetuity growth rates. With respect to projected cash flows, Evercore assumed a range of discount rates of 9.5% to 10.5%, a range of EBITDA multiples of 6.5x to 8.5x and a range of perpetuity growth rates of 0.5% to 1.5%. This analysis indicated a value of $8.96 to $11.64 per Common Unit.

        Evercore performed a similar discounted cash flow analysis utilizing an upside sensitivity to the Partnership projections that assumed the maximum contracted production volume under the Partnership's current contracts. This analysis indicated a value of $9.29 to $12.03 per Common Unit.

Table of Contents

        Evercore performed a similar discounted cash flow analysis utilizing a downside sensitivity to the Partnership projections that assumed the minimum contracted production volume under the Partnership's current contracts. This analysis indicated a value of $5.04 to $6.86 per Common Unit.

        With respect to projected distributions, Evercore calculated the implied per unit value range for the Common Units by utilizing a range of discount rates with mid-points equal to the Partnership's equity cost of capital, as estimated by Evercore based on CAPM, the Partnership's projected distribution per Common Unit for the six months ended December 31, 2014 and the calendar years 2014 through 2018, and terminal values as of December 31, 2018, based on a range of terminal exit yields. Evercore applied terminal exit yields of 12.0% to 14.0% and equity discount rates of 10.5% to 11.5%. This analysis indicated a value of $9.41 to $10.53 per Common Unit.

        Evercore reviewed and compared implied data for selected transactions which occurred since February 2010 involving target companies with assets that Evercore deemed to have certain characteristics that are similar to those of the Partnership's assets, although Evercore noted that none of the selected transactions or the selected companies that participated in the selected transactions were directly comparable to the Merger. Multiples for the selected transactions were based on publicly-available information.

        The maximum, minimum, mean and median transaction value to EBITDA multiples were 7.6x, 5.0x, 6.7x and 6.9x, respectively. Evercore reviewed the historical EBITDA multiples paid in the selected transactions and derived a range of relevant implied multiples of enterprise value ("EV") to EBITDA of 6.0x to 8.0x. Evercore applied these ranges of selected multiples to the Partnerships 2013 actual and 2014 estimated EBITDA provided by the management of the Partnership and described in "—Certain Unaudited Projected Financial Information Concerning the Partnership" below. For 2014, Evercore then applied a discount rate of 10.0% to the resulting value and further applied a discount rate of 10.0% to growth capital expenditures through the end of 2014, respectively. This analysis indicated equity value ranges for the Partnership of $8.58 to $12.76 per Common Unit.

        In order to assess how the public market values equity shares and units of similar publicly-traded Commodity Chemical Corporations ("C-Corp Chemicals") and variable rate master limited partnerships ("Variable Rate MLPs"), Evercore reviewed and compared specific financial and operating data relating to the Partnership to that of a group of selected C-Corp Chemicals and Variable Rate MLPs that Evercore deemed to have certain characteristics that are similar to those of the Partnership. Evercore noted, however, that none of the selected publicly-traded C-Corp Chemicals or Variable Rate MLPs are identical or directly comparable to the Partnership as a whole.

        As part of its analysis, Evercore calculated and analyzed (i) the ratios of EV to estimated 2014 and 2015 EBITDA for the selected C-Corp Chemicals and Variable Rate MLPs, (ii) the ratios of EV to estimated 2014 and 2015 EBITDA for the Partnership, (iii) the estimated 2014 distribution yield for the selected Variable Rate MLPs and (iv) the estimated 2014 distribution yield for the Partnership. Evercore calculated all multiples and yields based on closing share and unit prices, as applicable, as of May 23, 2014 for each respective C-Corp Chemical and Variable Rate MLP.

        The C-Corp Chemicals that Evercore deemed to have certain characteristics similar to those of the Partnership were the following:

        The Variable Rate MLPs that Evercore deemed to have certain characteristics similar to those of the Partnership were the following:

        The financial and operating data for the selected entities were based on publicly-available filings and financial projections provided by Wall Street equity research. The Partnership's projected financial metrics for 2014 and 2015 and related financial forecasts were provided by the management of the Partnership. The multiples of EV to EBITDA for the selected C-Corp Chemicals ranged from 6.5x to 8.0x for 2014 and from 6.1x to 7.5x for 2015. The multiples of EV to EBITDA for the selected Variable Rate MLPs ranged from 5.0x to 18.8x for 2014 and from 5.2x to 13.3x for 2015. Based on the resulting range of multiples and due to certain other considerations related to the specific characteristics of the C-Corp Chemicals and Variable Rate MLPs, in respect of the Partnership, Evercore deemed a range of 7.0x to 8.5x for 2014 and 6.0x to 8.0x for 2015 to be relevant. The projected distribution yields for the

48


Table of Contents

selected Variable Rate MLPs ranged from 5.4% to 15.1% for 2014. Based on the resulting range of distribution yields and due to certain other considerations related to the specific characteristics of the selected Variable Rate MLPs, in respect of the Partnership, Evercore deemed a range of 10.0% to 11.0% for 2014 to be relevant.

        Evercore then applied the relevant range of selected multiples to the corresponding financial data of the Partnership. This analysis indicated per Common Unit equity value ranges of $9.60 to $15.50 per Common Unit, as compared to the Public Merger Consideration of $14.00 per outstanding Common Unit owned by the Public Unitholders.

        Evercore reviewed the premiums offered or paid in 12 all cash industrials transactions since December 13, 2010 and 10 MLP unit-for-unit transactions since October 18, 1997 relative to the target share/unit prices one-day, five-day and 30-days prior to announcement as well as the target's 52-week high as of the date of the announcement. Evercore then applied the median of the relevant range of premiums to the relevant closing unit prices of the Partnership, which indicated a median implied transaction value range of $14.31 to $16.76 per Common Unit, as compared to the Public Merger Consideration of $14.00 per outstanding Common Unit owned by the Public Unitholders. There are no master limited partnership transactions that are exactly comparable to the Potential Transaction, partially due to the fact that none of the precedent master limited partnership transactions was an all cash transaction. The date, target, acquiror, and premiums for each of these 22 transactions is set forth below:

        Evercore analyzed Wall Street equity research analyst estimates of the potential future value (commonly referred to as price targets) of the Common Units based on publicly-available equity research published on the Partnership. These targets reflect each analyst's estimate of the future public market trading price of the Common Units and are not discounted to reflect present values. Evercore noted that the range of undiscounted equity analyst price targets of the Common Units published from April 11, 2014, to May 1, 2014, ranged from $12.00 to $17.00 per Common Unit. The public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the Common Units and these estimates are subject to uncertainties, including the future financial performance of the Partnership and future market conditions.

        The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by Evercore. In connection with the review of the Merger by the Board of Directors, Evercore performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary described above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Evercore's opinion. In arriving at its fairness determination, Evercore considered the results of all the analyses and did not draw, in isolation, conclusions from or with regard to any one analysis or factor considered by it for purposes of its opinion. Rather, Evercore made its determination as to fairness on the basis of its experience and

50


Table of Contents

professional judgment after considering the results of all the analyses. In addition, Evercore may have considered various assumptions more or less probable than other assumptions, so that the range of valuations resulting from any particular analysis described above should therefore not be taken to be Evercore's view of the value of the Partnership. No entity used in the above analyses as a comparison is directly comparable to the Partnership, and no precedent transaction used is directly comparable to the Merger. Further, Evercore's analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the entities, or transactions used, including judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of the Partnership.

        Evercore prepared these analyses for the purpose of providing an opinion to the Board of Directors as to the fairness of the Public Merger Consideration, from a financial point of view, as of the date of Evercore's opinion, to the Public Unitholders. These analyses do not purport to be appraisals or necessarily to reflect the prices at which the business or securities actually may be sold. Any estimates contained in these analyses are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by such estimates. Accordingly, estimates used in, and the results derived from, Evercore's analyses are inherently subject to substantial uncertainty, and Evercore assumes no responsibility if future results are materially different from those forecasted in such estimates. The aggregate Merger Consideration to be received by the Public Unitholders was determined through arm's length negotiations between the Partnership and Parent and was approved by the Board of Directors. Evercore did not recommend any specific consideration to the Board of Directors or that any given consideration constituted the only appropriate consideration.

        The Partnership has agreed to pay to Evercore an initial fee of $150,000, which became payable upon Evercore's engagement by the Board of Directors, an additional fee of $1,350,000, which became payable upon delivery of Evercore's opinion to the Board of Directors. The Partnership has also agreed to reimburse Evercore for its reasonable out-of-pocket third-party expenses incurred in connection with its engagement and has agreed to indemnify Evercore and its members, partners, officers, directors, advisors, representatives, employees, agents, affiliates or controlling persons, if any, against certain liabilities and expenses arising out of or in connection with Evercore's engagement.

        Evercore and its affiliates engage in a wide range of activities for their own accounts and the accounts of customers. In connection with these businesses or otherwise, Evercore and its affiliates and/or their respective employees, as well as investment funds in which any of them may have a financial interest, may at any time, directly or indirectly, hold long or short positions and may trade or otherwise effect transactions for their own accounts or the accounts of customers, in debt or equity securities, senior loans and/or derivative products relating to the Partnership, Lindsay Goldberg and its affiliates and Parent and its affiliates, for Evercore's own account and for the accounts of Evercore's customers and, accordingly, may at any time hold a long or short position in such securities or instruments.

        During the two-year period prior to the date of the opinion, no material relationship existed between Evercore and its affiliates and the Partnership, Lindsay Goldberg and its affiliates or Parent and its affiliates and no compensation was received by Evercore or its affiliates from the Partnership, Lindsay Goldberg and its affiliates or Parent and its affiliates. Evercore may provide financial or other services to Parent, Lindsay Goldberg or its affiliates or Parent or its affiliates in the future and in connection with any such services it may receive compensation.

        The Board of Directors engaged Evercore to act as its financial advisor based on its qualifications, experience and reputation. Evercore is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses in connection with mergers and acquisitions, leveraged buyouts, competitive biddings, private placements and valuations for corporate and other purposes.

Certain Unaudited Projected Financial Information Concerning the Partnership

        The Partnership does not as a matter of course publicly disclose long-term forecasts or internal projections as to future performance, revenues, earnings, financial condition or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. However, in connection with the Board of Directors' review of strategic alternatives, our management prepared unaudited projected financial information on a stand-alone, pre-merger basis. The Partnership is providing the unaudited projected financial information in this information statement to provide the Unitholders access to certain non-public unaudited projected financial information that was made available to the Board of Directors' financial advisors in connection with the Merger. The unaudited projected financial information was not prepared with a view toward public disclosure, and the inclusion of this information should not be regarded as an indication that the Partnership or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual future results. Neither the Partnership nor any of its affiliates assumes any responsibility for the accuracy of this information. Readers of this information statement are cautioned not to place undue reliance on the unaudited projected financial information. No one has made or makes any representation to any Unitholder regarding the information included in the unaudited projected financial information or the ultimate performance of the Partnership compared to the information included in the unaudited projected financial information.

        The unaudited projected financial information was not prepared with a view toward complying with generally accepted accounting principles ("GAAP"), the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants with respect to the preparation or presentation of projected financial information. Certain of the unaudited projected financial information presents financial metrics that were not prepared in accordance with GAAP. These non-GAAP financial measures may be different from non-GAAP financial measures used by other companies. The Partnership has not prepared, and neither the Board of Directors nor its financial advisors have considered, a reconciliation of these non-GAAP financial measures to applicable GAAP financial measures.

        There can be no assurance that the assumptions made in preparing such information will prove accurate or that the projected results reflected therein will be realized. Neither the Partnership's independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the unaudited projected financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for the unaudited projected financial information and disclaim any association with, the projected financial information. Furthermore, the unaudited projected financial information does not take into account any circumstance or event occurring after the date it was prepared or which may occur in the future, and, in particular, does not take into account any revised prospects of the Partnership's business, changes in general business, regulatory or economic conditions, competition or any other transaction or event that has occurred since the date on which such information was prepared or which may occur in the future.

        While presented with numeric specificity, the unaudited projected financial information reflects numerous estimates and assumptions made by our management with respect to industry performance and competition, general business, economic, market and financial conditions and matters specific to the Partnership's business, all of which are difficult to predict and many of which are beyond the Partnership's control. As a result, the unaudited projected financial information reflects numerous assumptions and estimates as to future events and there can be no assurance that these assumptions will accurately reflect future conditions, that the unaudited projected financial information will be realized or that actual results will not be significantly higher or lower than estimated. Since the unaudited projected financial information covers multiple years, such information by its nature becomes less predictive with each successive year.

        The unaudited projected financial information includes forward-looking statements and is based on estimates and assumptions that are inherently subject to factors such as industry performance, competition, general business, economic, regulatory, market and financial conditions, as well as changes to the business, financial condition or results of operations of the Partnership, including the factors described under "Cautionary Note Regarding Forward-Looking Statements" and other risk factors as disclosed in the Partnership's filings with the SEC that could cause actual results to differ materially from those shown below. The Partnership's Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and its Quarterly Report on Form 10-Q for the quarter ended March 31, 2014 are included as Annex E and Annex F, respectively, to this information statement. Unitholders are urged to review the reports for a description of risk factors with respect to the Partnership's business and for a description of the Partnership's reported results of operations, financial condition and capital resources. See also "Where You Can Find More Information." The unaudited projected financial information does not take into account any of the Transactions, including the Merger.

        For the foregoing reasons, as well as the bases and assumptions on which the unaudited projected financial information was compiled, the inclusion of the Partnership's unaudited projected financial information in this information statement should not be regarded as an indication that such information will be predictive of future results or events nor construed as financial guidance, and it should not be relied on as such or for any other purpose whatsoever.

        THE PARTNERSHIP HAS NOT UPDATED AND DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE PROJECTED FINANCIAL INFORMATION SET FORTH ABOVE, INCLUDING, WITHOUT LIMITATION, TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE SUCH INFORMATION WAS PREPARED OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, INCLUDING, WITHOUT LIMITATION, CHANGES IN GENERAL ECONOMIC, REGULATORY OR INDUSTRY CONDITIONS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE PROJECTED FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE.

Financing of the Merger

        Parent's obligation to consummate the Merger is not conditioned upon Parent obtaining financing. Parent has advised us that it will have available at the closing date of the Merger the necessary funds from its cash on hand to consummate the Merger.

Material U.S. Federal Income Tax Consequences of the Merger to Our Unitholders

        The following discussion describes the material United States federal income tax consequences to Unitholders who are U.S. holders (as defined below) of the exchange of their Common Units for Merger Consideration pursuant to the Merger.

        For purposes of this discussion, the term "U.S. holder" means a beneficial owner of Common Units that is for U.S. federal income tax purposes (i) an individual citizen or resident of the United States, (ii) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof or the District of Columbia, (iii) a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (B) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes or (iv) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source.

        This discussion does not address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax. This discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), the regulations promulgated thereunder, Internal Revenue Service ("IRS") rulings and judicial decisions now in effect. These authorities may change, possibly retroactively, and any change could affect the accuracy of the statements and conclusions set forth in this discussion.

        This discussion addresses only those Unitholders who hold their Common Units as "capital assets" within the meaning of Section 1221 of the Code (generally, property held for investment). Further, this discussion does not address all aspects of U.S. federal income taxation that may be relevant to a Unitholder in light of such Unitholder's individual circumstances or that may be applicable to a Unitholder that is subject to special treatment under the U.S. federal income tax laws, including any Unitholder that:

54


Table of Contents

        If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Common Units, the tax treatment of a partner (or owner of such entity) will generally depend upon the status of the partner (or owner of such entity) and the activities of the partnership (or entity). Any entity treated as a partnership for U.S. federal income tax purposes that holds Common Units, and any partners in such partnership (or any owners of such entity), should consult their own tax advisors with respect to the tax consequences of the transactions in their specific circumstances.

        UNITHOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.

        An exchange of Common Units for the Merger Consideration will be a taxable transaction for U.S. federal income tax purposes. In addition, Unitholders receiving Merger Consideration in exchange for Common Units pursuant to the Merger will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between:

        Subject to the discussion immediately below, such gain or loss generally will be long-term capital gain or loss if the Unitholder's holding period for the Common Units exceeds one year at the Effective Time of the Merger. Long-term capital gains of non-corporate Unitholders generally are eligible for reduced rates of U.S. federal income taxation. It is possible, however, that the IRS my recharacterize a portion of the proceeds in a manner that results in a different character of income. In addition, any net gains recognized by Unitholders who are individuals, estates or trusts may be subject to tax imposed on "net investment income" under Section 1411 of the Code. Because the Merger will be a fully taxable transaction to Unitholders and will terminate a Unitholder's entire interest in the Partnership, any remaining passive losses attributable to the ownership of such Common Units (including suspended passive activity losses from prior years) generally will no longer be treated as passive losses and thus should be available to offset Unitholders' other gain or income (though the use of such losses may be subject to other limitations).

        Upon exchanging Common Units for the Merger Consideration, a Unitholder may be treated as recognizing ordinary income (or loss) to the extent the Merger Consideration received is attributable to the Partnership's "unrealized receivables" (including potential recapture items such as depreciation) or "inventory items." Under Section 751 of the Internal Revenue Code, the Merger Consideration generally is divided between such items and all other items, resulting in two constructive taxable transactions in which gain or loss is separately computed. Ordinary income attributable to unrealized receivables and inventory items may exceed overall net taxable gain realized upon the exchange of Common Units in the Merger and may be recognized even if an overall net taxable loss is realized. Thus, a Unitholder may recognize both ordinary income and a capital loss.

55


Table of Contents

        Unitholders will be allocated their proportionate shares of the Partnership's items of income, gain, loss and deduction, for the period ending at the end of the day immediately preceding the closing date of the Merger. These allocations will be made in accordance with the terms of our Partnership Agreement and taking into account any required special allocations. When computing their taxable income or loss, Unitholders will be required to take into account their share of such income or loss. These allocations will result in adjustments to each Unitholder's tax basis in the Common Units held by that Unitholder and, therefore, may potentially affect the gain or loss resulting from the Merger.

        As a result of one or more transfers of interests in the Partnership pursuant to the Support Agreements, the Partnership will terminate for U.S. federal income tax purposes pursuant to Section 708(b)(1)(B) of the Code, effective immediately prior to the Effective Time. As a result of the Merger itself, the Partnership will undergo a second termination for U.S. federal income tax purposes pursuant to Section 708(b)(1)(B) of the Code, at the effective time of the Merger. As a technical matter, the two terminations may result in Unitholders receiving two Schedules K-1 from the Partnership for the period prior to the Merger; however, we anticipate receiving consent from the Internal Revenue Service to send a single consolidated Schedule K-1 for the period prior to the Merger.

        Parent and the paying agent are authorized to deduct and withhold from the Merger Consideration otherwise payable pursuant to the Merger Agreement any applicable taxes required to be withheld in respect of such consideration.

Interests of Directors and Executive Officers in the Merger

        Members of the Board of Directors and our executive officers have various interests in the Merger described in this section that may be different from, or in addition to, the interests of our Unitholders generally. The Board of Directors was aware of and considered these potential interests, among other matters, in evaluating and declaring the Merger Agreement and the Transactions to be advisable and in the best interests of the Partnership, our general partner and the Unitholders.

        For a discussion of certain obligations of David Lumpkins and Nathan Ticatch, our co-principal executive officers and Founding Unitholders, see "Support Agreements."

        The Merger Agreement requires that, for the 12-month period following the closing date of the Merger, our employees who remain employed with the Partnership, its subsidiaries or our general partner following the consummation of the Merger, including any of our executive officers, will receive base salaries at least equal to the salaries in effect for such employees as of May 27, 2014. Our executive officers are David Lumpkins, Nathan Ticatch, Sharon Spurlin, Richard Rice, Hank Jeans and Randy Miller, and these individuals are also our "named executive officers" identified in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, which is included as Annex E to this information statement. While it is contemplated that Messrs. Lumpkins, Ticatch and Rice and Ms. Spurlin will resign effective as of the day following the consummation of the Merger, Messrs. Jeans and Miller are anticipated to continue to remain employed with the Partnership, its subsidiaries or our general partner following the consummation of the Merger.

        For the period beginning on the closing date of the Merger and ending on the last day of the calendar year in which the consummation of the Merger occurs, our employees, including our executive officers, who remain employed with the Partnership, its subsidiaries or our general partner following

56


Table of Contents

the consummation of the Merger, will be provided employee benefits pursuant to the benefit plans of the MLP Entities in effect as of the closing date of the Merger, which will include annual discretionary bonuses as determined by the board of directors or similar governing body of the surviving entity. No bonus payments, pro-rata or otherwise, will be made to our employees upon the consummation of the Merger, other than as described below under "—Retention Arrangements" and "—Change-in-Control Severance Arrangements" in the event of certain terminations of employment.

        Parent has agreed to continue our 401(k) plan through the last day of the calendar year in which the consummation of the Merger occurs and to make matching contributions and profit sharing contributions determined in the same manner in the ordinary course consistent with past practice. On the last day of the calendar year in which the consummation of the Merger occurs, each individual who is an employee on the closing date of the Merger will be fully vested in any account balance he or she has under our 401(k) plan on the last day of the calendar year in which the consummation of the Merger occurs. Parent has agreed that it will, or will cause one of its affiliates to, take any and all actions necessary, including amending our 401(k) plan to effectuate the full vesting and to ensure that no amounts will be forfeited on an employee's termination of employment following the closing of the Merger if such employee maintains an account balance under our 401(k) plan on the last day of the calendar year in which the closing of the Merger occurs.

        The Partnership previously granted Phantom Units pursuant to the LTIP to certain of our executive officers and other employees and members of the Board of Directors. A Phantom Unit is a notional unit granted under the LTIP that, upon vesting, entitles the holder to receive, at the time of settlement, a fully vested Common Unit. The Merger Agreement provides that each Phantom Unit outstanding immediately prior to the Effective Time, whether or not vested, will, at the Effective Time, (i) be cancelled and converted into the right to receive an amount of cash equal to the Phantom Unit Consideration, less required tax withholding, (ii) no longer be outstanding, and (iii) cease to exist, upon the terms and subject to the conditions set forth in the Merger Agreement.

        The following table sets forth the number of outstanding Phantom Units held by each of our executive officers and members of the Board of Directors as of May 27, 2014 and the gross cash proceeds, without giving effect to any required tax withholdings, that each individual would be entitled to receive with respect to the Phantom Units upon the consummation of the Merger. Other members of the Board of Directors do not hold any Phantom Units.

Does not include value attributable to any outstanding Common Units owned by executive officers and directors.

        In order to promote the retention of key employees during the period prior to and following the consummation of the Merger, on the Partnership's first payroll date following the 12-month anniversary of the closing date of the Merger, Parent is to pay each employee, including any of our executive officers, who has remained employed with the Partnership, its subsidiaries or our general partner until the date that is 12 months following the closing date of the Merger a retention bonus equal to eight weeks of the employee's then-current base salary. It is contemplated that Messrs. Lumpkins, Ticatch and Rice and Ms. Spurlin will resign effective as of the day following consummation of the Merger. However, Messrs. Jeans and Miller are anticipated to be eligible, subject to satisfaction of the conditions described above, to receive retention bonuses of $39,231 and $44,615, respectively.

        In connection with the Merger, certain of our executive officers and other employees will be eligible to participate in a change-in-control severance plan, pursuant to which Parent has agreed to make, or to cause one of its affiliates to make, severance payments to certain employees, including certain of our executive officers upon a termination of employment (i) by Parent without "cause," (ii) by the employee for "good reason," or (iii) in the case of Ms. Spurlin and Mr. Rice, upon their resignation, in any case, if such termination occurs during the period commencing on the closing date of the Merger and ending on the 12-month anniversary of the closing date of the Merger (subject to the execution and non-revocation by such employee of a release). Messrs. Lumpkins and Ticatch are not eligible to receive payments from Parent as described above.

        Upon termination of employment as described above, Ms. Spurlin and Messrs. Rice, Jeans and Miller are entitled to receive a lump sum payment equal to the sum of:

        It is contemplated that Ms. Spurlin and Mr. Rice will resign effective as of the day following consummation of the Merger. Upon their resignation, they will receive payments as described above.

        For purposes of the change-in-control severance plan, (i) "cause" generally means (A) commission of a criminal act, including fraud, theft, misappropriation, dishonesty or embezzlement or any other crime that, in the discretion of the Parent, is found to involve moral turpitude, (B) willful engagement in acts that the employee knew or should have known in the exercise of reasonable care, would cause material harm or substantial risk of material harm to Parent's property, goodwill or existing business interests, (C) failure or refusal to substantially perform previously identified job duties after reasonable notice and opportunity to correct the same, or (D) engagement through act or omission in a material

58


Table of Contents

breach of any of Parent's applicable policies, practices or procedures; and (ii) "good reason" generally means (A) a material decrease in the employee's base salary, (B) a relocation of the employee's principal office to a location that is in excess of 25 miles from its location as of the closing date of the Merger, or (C) without the employee's prior consent, a material adverse change in the employee's duties, subject to certain notice, cure and timing requirements.

        The aggregate amount of cash severance and benefits potentially payable in accordance with the change-in-control severance plan to our executive officers, assuming the Merger occurs on August 1, 2014 and assuming each eligible executive officer experienced a qualifying termination of employment on such date, is set forth in the table below under "—Quantification of Potential Payments to Executive Officers in Connection with the Merger."

        The Merger Agreement provides that following the Merger, solely to the extent that any MLP Group Entity would be obligated to indemnify any director or officer, Parent and the surviving company will, jointly and severally, (i) indemnify such individuals against any costs and expenses, claims or other liabilities and provide advancement of expenses and (ii) honor the provisions regarding indemnification and advancement of expenses provided in the charter documents (or comparable organizational documents) of the MLP Group Entity. Prior to the Merger, the Partnership will purchase a six-year "tail" directors' and officers' liability insurance policy.

        The following table show the aggregate dollar value of the various elements of compensation that each of our named executive officers could receive in connection with the Merger from the Partnership and Parent, as required by Item 402(t) of Regulation S-K, assuming (i) the Merger is consummated on August 1, 2014, and (ii) the employment or service of each of our named executive officers is terminated (A) in the case of Messrs. Jeans and Miller, by Parent or one of its subsidiaries without "cause" or by Mr. Jeans or Mr. Miller for "good reason," and (B) in the case of Ms. Spurlin and Mr. Rice, upon to their resignation (in any case, if such termination occurs during the period commencing on the closing date of the Merger and ending on the 12-month anniversary of the closing date (subject to the execution and non-revocation by such employee of a release)). As described below, some of the amounts set forth in the table would be payable by virtue of the consummation of the Merger alone ("single-trigger" payments) and some amounts would be payable only if a termination of employment or service occurs in connection with or following the Merger ("double-trigger" payments). In addition to the assumptions regarding the consummation date of the Merger and the termination of the employment or service of the named executive officers, the estimates provided in the table below are based on certain other assumptions that are described in the footnotes accompanying the table

(a)
Amounts represent the aggregate dollar amount of cash severance payments to which the named executive officers would be entitled to receive pursuant to the change-in-control severance plan upon the consummation of the Merger followed by a termination of employment. The lump sum payment consists of 52 weeks of base salary for Mr. Rice and Ms. Spurlin and 24 weeks of base salary for Messrs. Jeans and Miller plus the pro rata portion of the executive's annual target bonus as of August 1, 2014. For purposes of Item 402(t) of Regulation S-K, (i) the payments to Messrs. Jeans and Miller are "double-trigger," as they will generally only be payable in the event of a qualifying termination following consummation of the Merger, and (ii) the payments to Ms. Spurlin and Mr. Rice are "single-trigger" since they have the ability to resign voluntarily without good reason and still receive these payments. The amounts are based on the named executive officers' base salaries currently in effect. If base salaries are increased, actual payments may be greater than those indicated above. If Messrs. Jeans and Miller remain employed by Parent or one of its subsidiaries (including the surviving entity) on the 12-month anniversary of the closing date of the Merger, they will be entitled to receive the retention bonuses described above under "—Retention Arrangements." Assuming the Merger is consummated on August 1, 2014, the components of the cash severance payments would be as follows:

Dissenters' Rights

        Under the Delaware Revised Uniform Limited Partnership Act and our Partnership Agreement, there are no dissenters' or appraisal rights for Unitholders in connection with the Merger or the other Transactions.

Form of the Merger

        On the terms and subject to the conditions of the Merger Agreement and in accordance with Delaware law and our Partnership Agreement, at the Effective Time, the membership interests in Merger Sub that are issued and outstanding immediately prior to the Effective Time will be converted into 100.0% of the limited partner interests in the Partnership, as the surviving entity. Any Common Units that are issued and outstanding and owned by Parent or any affiliate of Parent will be automatically cancelled and will cease to exist, and no consideration will be delivered in exchange for such cancelled Common Units. The general partner's non-economic general partner interest in the Partnership that is issued and outstanding immediately prior to the Effective Time (the "General Partner Interest") will be unaffected by the Merger and will remain outstanding. Upon the GP Equity

61


Table of Contents

Transfer, the General Partner Interest will be owned, directly or indirectly, by Parent (or one or more of affiliates of Parent). Merger Sub will merge with and into the Partnership, as a result of which the Partnership will cease to be an independent, publicly-traded entity and each Common Unit issued and outstanding will be automatically cancelled and cease to exist.

Conversion of Common Units; Procedures for Exchange of Common Units; Payment of Merger Consideration and Merger Related Distribution

        The conversion of Common Units into the right to receive the Merger Consideration in cash, without interest and subject to any required withholding taxes, will occur automatically upon the Effective Time. On or prior to the closing date of the Merger, Parent will appoint a paying agent reasonably acceptable to the Partnership (the "Paying Agent") for the purpose of exchanging Common Units held of record in book-entry form ("Book-Entry Units") for the Merger Consideration and the Merger Related Distribution.

        Prior to the closing of the Merger, Parent will deposit with the Paying Agent an amount of cash equal to the sum of the aggregate Public Merger Consideration plus the aggregate Sponsor Merger Consideration, and the Partnership will deposit an amount of cash equal to the aggregate Merger Related Distribution. The paying agent will invest the deposits, subject to provisions that the investments will be obligations of or guaranteed by the United States of America or rated A-1 or P-1 or better by Moody's Investors Service, Inc. or Standard & Poor's Corporation. Any interest from such investments belongs to Parent, not the Unitholders.

        As soon as reasonably practicable after the Effective Time, but in no event more than three business days following the Effective Time, Parent will send, or will cause the Paying Agent to send, to each holder of Book-Entry Units (other than The Depository Trust Company ("DTC")) as of the Effective Time (and, to the extent commercially practicable, Parent will, or will cause the Paying Agent to, make available for collection by hand, during customary business hours commencing immediately after the Effective Time, if so elected by a holder of Book-Entry Units), a letter of transmittal (each such letter, a "Letter of Transmittal") to be used for surrender of Book-Entry Units. Each holder of Book-Entry Units other than DTC, upon surrender thereof by delivery of a Letter of Transmittal, duly executed and completed in accordance with the terms of such Letter of Transmittal, will be entitled to receive in exchange for each surrendered Book-Entry Unit a cash amount equal to the sum of the Merger Consideration and the Merger Related Distribution to which such Unitholder is entitled ("Merger Related Consideration"), after giving effect to any required tax withholdings. DTC, upon surrender of its Book-Entry Units in accordance with the customary surrender procedures of DTC and the Paying Agent, will be entitled to receive in exchange for each surrendered Book-Entry Unit a cash amount equal to the Merger Related Consideration. Each Book-Entry Unit so surrendered will be cancelled.

        The Merger Related Consideration will be paid to (i) the holders of Book-Entry Units other than DTC, as promptly as practicable after receipt by the Paying Agent of the Letter of Transmittal in respect thereof, by mail or wire transfer of immediately available funds and (ii) DTC, as promptly as practicable after the Effective Time, by wire transfer of immediately available funds. Generally, payment of the Merger Related Consideration with respect to Book-Entry Units will only be made to the person in whose name such Book-Entry Units are registered; however, subject to certain requirements, Merger Related Consideration may be paid to a person other than the person in whose name the Common Units surrendered are registered. No interest will be paid or accrued on any amount payable upon due surrender of Book-Entry Units. Until surrendered and paid as contemplated in the Merger Agreement, each Book-Entry Unit will be deemed at any time after the Effective Time to represent only the right to receive the Merger Related Consideration in cash as contemplated by the Merger Agreement. The Merger Related Consideration paid upon surrender of such Book-Entry Units will be deemed to have been paid in full satisfaction of all rights pertaining to such Book-Entry Units.

Table of Contents

        No person beneficially owning Common Units through DTC will be required to deliver a Letter of Transmittal to receive the Merger Related Consideration that such holder is entitled to receive through DTC. Any such person will receive its Merger Related Consideration in accordance with the customary payment procedures of DTC following the Effective Time.

Delisting and Deregistration of Our Common Units

        If the Merger is consummated, Common Units will be delisted from the NYSE and deregistered under the Securities Exchange Act of 1934 (the "Exchange Act").

Regulatory Approvals Required for the Merger

        Under the Hart-Scott-Rodino Act, the Merger may not be consummated until the Partnership and Parent have filed notification and report forms with the U.S. Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice and the applicable waiting period has expired or been terminated. On June 6, 2014, the Partnership and Parent each filed a Notification and Report Form with the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice and requested an early termination of the waiting period. If the early termination is not granted and a request for additional information by the relevant antitrust authorities is not made, the waiting period will expire at 11:59 p.m. (Eastern Time) on July 7, 2014.

        Under the Merger Agreement, both the Partnership and Parent have agreed to cooperate with each other and use their respective reasonable best efforts to obtain all required governmental approvals and avoid any action or proceeding by a governmental entity to the extent necessary, proper or advisable to consummate the Merger, subject to exceptions for any divestitures or similar actions that may be required of the parties. Except as noted above with respect to the required filings under the Hart-Scott-Rodino Act, the expiration of 20 days following the mailing of this information statement to our Unitholders and the filing of a certificate of merger in Delaware on the closing date of the Merger, we are unaware of any material federal, state or foreign regulatory requirements or approvals required for the execution of the Merger Agreement or consummation of the Transactions.

Litigation Related to the Merger

        On June 2, 2014, a putative Unitholder class action complaint, captioned Klemesrud v. PetroLogistics LP, et al., C.A. No. 9723-VCP, which we refer to as the "Klemesrud Action," was filed in the Court of Chancery of the State of Delaware. Between June 4 and June 19, 2014, two additional putative Unitholder class action complaints, captioned Swanson v. PetroLogistics LP, et al., C.A. No. 9737-VCP, which we refer to as the "Swanson Action," and Henry v. PetroLogistics LP, et al., C.A. No. 9759-VCP, which we refer to as the "Henry Action," were filed in the Delaware Court, and two additional putative Unitholder class action complaints, captioned Basaraba v. PetroLogistics LP, et al., No. 4:14-cv-1558, which we refer to as the "Basaraba Action," and Wolfson v. PetroLogistics LP, et al., No. 4:14-cv-1723, which we refer to as the "Wolfson Action," were filed in the United States District Court for the Southern District of Texas, Houston Division. Each of the complaints names the MLP Entities, the members of the Board of Directors, GP Holdings and the Parent Entities as defendants, and the complaints in the Klemesrud Action and the Henry Action also name Koch Industries, Inc. or Koch Industries, LLC as defendants. In each of the complaints, the plaintiffs generally allege that the members of the Board of Directors breached their duties to the Unitholders by entering into the Merger Agreement and further allege that the other defendants aided and abetted the alleged breaches of duty by the members of the Board of Directors. The Henry Action also alleges that the defendants breached the terms of our Partnership Agreement, and the Wolfson Action alleges that the defendants violated Sections 14(a) and 20(a) of the Exchange Act by issuing an information statement that omits and/or misrepresents material information concerning the Merger. In each of the complaints, the plaintiffs seek, among other things, to enjoin the Merger and/or money damages.

THE MERGER AGREEMENT

        This section of this information statement describes the material provisions of the Merger Agreement but does not purport to describe all of the terms of the Merger Agreement. The following summary is qualified in its entirety by reference to the complete text of the Merger Agreement, which is included as Annex A to this information statement and is incorporated by reference in this section. We urge you to read the full text of the Merger Agreement because it is the legal document that governs the Merger. This section is not intended to provide you with any factual information about us. This information can be found elsewhere in this information statement and in the public filings we make with the SEC. Our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2014 are included as Annex E and Annex F, respectively, to this information statement. See also "Where You Can Find More Information."

Explanatory Note Regarding the Merger Agreement

        The Merger Agreement is included to provide you with information regarding its terms. It is not intended to provide any other factual information about the Partnership, Parent or any of their respective subsidiaries or affiliates. Factual disclosures about the Partnership contained in this information statement or in the Partnership's public reports filed with the SEC may supplement, update or modify the factual disclosures about the Partnership contained in the Merger Agreement. The representations and warranties of the Partnership contained in the Merger Agreement have been made solely for the benefit of Parent and Merger Sub. In addition, these representations and warranties (i) have been made only for purposes of the Merger Agreement, (ii) may be subject to limits or exceptions agreed upon by the contracting parties, (iii) were made only as of the date of the Merger Agreement or other specific dates and (iv) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as facts. Additionally, the representations, warranties, covenants, conditions and other terms of the Merger Agreement may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Partnership's public disclosures.

The Merger

        Subject to the terms and conditions of the Merger Agreement, Merger Sub, a subsidiary of Parent, will merge with and into the Partnership, with the Partnership continuing as the surviving entity. As a result of the Merger, we will cease to be an independent, publicly-traded entity. The Merger will be effective at the time a certificate of merger is duly filed with the Secretary of State of the State of Delaware (or at a later time, if agreed upon by the parties and specified in the certificate of merger filed with the Secretary of State). See "The Merger—Form of the Merger."

Merger Consideration

        Upon the completion of the Merger, each Common Unit issued and outstanding immediately prior to the Effective Time will be cancelled and converted automatically into the Merger Consideration, which represents the right of (i) the Public Unitholders to receive the Public Merger Consideration and (ii) the Principal Unitholders to receive the Sponsor Merger Consideration, in each case without interest and subject to any required withholding taxes.

        It is anticipated that all Unitholders of record on the day preceding the closing date of the Merger will also receive the Merger Related Distribution, a final one-time cash distribution in connection with, and conditioned upon, the closing of the Merger, which will be declared and made in accordance with

64


Table of Contents

the provisions of the Merger Agreement. The Merger Related Distribution will be calculated to approximate the distribution that would have otherwise been paid for the period through the closing date of the Merger, subject to an additional reserve of $12.3 million to cover a portion of the Transaction-related costs of the Partnership.

Certificate of Limited Partnership; Partnership Agreement

        Our certificate of limited partnership will remain in effect immediately prior to the Effective Time and will remain unchanged and will be the certificate of limited partnership of the surviving entity. The Partnership Agreement as in effect immediately prior to the Effective Time will remain unchanged, except as otherwise provided in the Merger Agreement, and will be the Partnership Agreement of the surviving entity.

Treatment of Phantom Unit Awards

        The Merger Agreement provides that each Phantom Unit that is outstanding as of immediately prior to the Effective Time, whether or not vested, will, at the Effective Time, (i) be cancelled and converted into the right to receive from Parent (through our general partner) the Phantom Unit Consideration, which is an amount of cash, less required tax withholding, equal to the Public Merger Consideration plus the Merger Related Distribution, (ii) no longer be outstanding, and (iii) cease to exist, upon the terms and subject to the conditions set forth in the Merger Agreement. Following the Effective Time, Parent will cause our general partner to pay the Phantom Unit Consideration in full satisfaction of all rights pertaining to the Phantom Units formerly outstanding to each holder of Phantom Units that executes and delivers an acknowledgement, with such payment generally to be made as promptly as practicable following delivery thereof.

No Dissenters' Rights

        Under the Delaware Revised Uniform Limited Partnership Act and our Partnership Agreement, there are no dissenters' or appraisal rights for Unitholders in connection with the Merger or the other Transactions.

Payment for the Units

        Prior to the closing of the Merger, Parent will deposit with the Paying Agent an amount of cash equal to the sum of the aggregate Public Merger Consideration plus the aggregate Sponsor Merger Consideration, and the Partnership will deposit an amount of cash equal to the aggregate Merger Related Distribution. The Merger Related Distribution and the Merger Consideration will be paid to Unitholders as described above under "The Merger—Conversion of Common Units; Procedures for Exchange of Common Units; Payment of Merger Consideration and Merger Related Distribution."

Unitholder Action by Written Consent

        Following the execution of the Merger Agreement, we received and delivered to Parent the Unitholder written consent approving the Merger Agreement and the Transactions, dated May 27, 2014, executed by the Principal Unitholders, which on such date owned Common Units representing 72.9% of the outstanding Common Units entitled to vote on the approval of the Merger Agreement and the Transactions. Therefore, no further Unitholder approval is required in connection with the Merger Agreement or the Transactions.

Cooperation

        The term "divestiture condition" means (i) any restriction, prohibition or limitation of ownership or operation by Parent or Merger Sub or their respective affiliates of all or any portion of the businesses or assets of the MLP Group Entities in any manner in any part of the world, (ii) any requirement that Parent or Merger Sub or any of their respective affiliates or any MLP Group Entity to sell, divest, hold separate or otherwise dispose of, or enter into a voting trust, proxy or "hold separate" contract or similar contract with respect to, all or any portion of their respective businesses or assets or (iii) any restriction, prohibition or limitation on the ability of Parent or Merger Sub or any of their respective affiliates or any MLP Group Entity to conduct their respective businesses, enter into any new line of business or own or operate any of their respective assets, in each case, in any manner in any part of the world.

The MLP Entities are obligated to promptly (and, in any event, within 24 hours) notify Parent orally and in writing of (i) any inquiries, proposals or offers with respect to an alternative proposal or requests for non-public information that are received and (ii) any amendment or modification of, or development with respect to, any such inquiries, proposals, offers or requests.

        Notwithstanding the restrictions described above, subject to the conditions described below and solely in response to a bona fide alternative proposal made on or after the date of the Merger Agreement and prior to the expiration of the Unitholder Consent Period, the MLP Entities may, with respect to the third party that has made such bona fide alternative proposal: (i) in response to a request therefor by such third party, provide information to the third party and afford the third party with access to the books, records and representatives of the MLP Group Entities and (ii) engage or participate in any discussions or negotiations with the third party with respect to the bona fide alternative proposal. The MLP Entities may not take such actions unless, prior to taking such actions, the following conditions have been satisfied: (i) the MLP Entities have received from the third party an executed acceptable confidentiality agreement and disclosed to Parent any non-public information to be provided to the third party that has not been previously disclosed to Parent; (ii) the MLP Entities have delivered to Parent a written notice (A) stating that the Board of Directors intends to take such actions, (B) stating that the Board of Directors has made the determination described in the following clause (iii) and (C) including an unredacted copy of the bona fide alternative proposal; and (iii) the Board of Directors has determined that the bona fide alternative proposal constitutes a superior proposal or is reasonably likely to result in a superior proposal.

If Parent desires to exercise its match right, during the four business day period commencing on Parent's receipt of such notice, the MLP Entities must engage in good faith negotiations with Parent regarding an amendment of the Merger Agreement so that the alternative proposal that is the subject of such notice ceases to be a superior proposal. If the financial or other material terms or conditions of such bona fide alternative proposal are amended or modified, the MLP Entities must deliver a new notice and the negotiation period will be extended by an additional two business days from Parent's receipt of the new notice.

        Similarly, the Board of Directors will be entitled to effect a withdrawal of recommendation in connection with an intervening event only if: (i) the MLP Entities have delivered to Parent a written notice (A) stating that the Board of Directors intends to effect a withdrawal of recommendation, (B) stating that (1) the Board of Directors has determined that an intervening event has occurred and is continuing and (2) the Board of Directors has determined in good faith, after consultation with its outside financial and legal advisors, that the Transactions are not in the best interests of the Unitholders and (C) including a summary, in all material respects, of the intervening event; and (ii) the negotiation period described below has expired. If Parent desires to exercise its match right, during the four business day period commencing on Parent's receipt of such notice, the MLP Entities must engage in good faith negotiations with Parent regarding an amendment of the Merger Agreement so that the Board of Directors will no longer be entitled to effect a withdrawal of recommendation. If there is a material change to the facts or circumstances relating to the intervening event, the MLP Entities must deliver a new notice and the negotiation period will be extended by an additional two business days from Parent's receipt of the new notice.

        If the parties to the Merger Agreement enter into an amendment in connection with a superior proposal or an intervening event and Parent reasonably requests written consents from our general partner and the Unitholders approving the amendment, the MLP Entities will deliver a consent from our general partner and will promptly take all action necessary to seek to obtain the written consent of our Unitholders.

        The term "agreed merger consideration differential" means the value differential by which the Public Merger consideration to be paid to the Public Unitholders exceeds the Sponsor Merger Consideration to be paid to the Sponsors and Founding Unitholders on the terms and subject to the conditions of the Merger Agreement (i.e. the $2.00 per common unit spread between the Public Merger Consideration and the Sponsor Merger Consideration).

        The term "alternative proposal" means any proposal or offer made by a person (other than Parent or Merger Sub) relating to (i) any direct or indirect acquisition or purchase, in a single transaction or a series of related transactions, of (A) 5.0% or more of the consolidated total assets of the MLP Group Entities, taken as a whole, or (B) 5.0% or more of any class of outstanding equity interests of any MLP Group Entity, (ii) any tender offer or exchange offer that if consummated would result in any person beneficially owning, directly or indirectly, 5.0% or more of any class of outstanding equity interests of any MLP Group Entity, (iii) any merger, consolidation, exclusive license, business combination, joint venture, partnership, share exchange or other transaction involving any MLP Group Entity pursuant to which any person or its holders of equity interests would beneficially own, directly or indirectly, 5.0% or more of any class of outstanding equity interests of any MLP Group Entity or the direct or indirect parent of any MLP Group Entity or the surviving entity resulting, directly or indirectly, from any such transaction or (iv) concerning any recapitalization, liquidation, dissolution or any other similar transaction involving any MLP Group Entity, in each case, other than the Transactions. In the event of a termination by Parent due to a breach by either MLP Entity or GP Holdings of their respective covenants under the Merger Agreement (other than the no solicitation covenants), sales of Common Units by the Principal Unitholders that occur within 12 months after such termination by means of a

secondary offering to the public that has been registered under the Securities Act will not be deemed to involve an alternative proposal for the purposes of this definition.

        The term "bona fide alternative proposal" means an unsolicited written bona fide alternative proposal that was not received or obtained in violation of the Merger Agreement.

        The term "intervening event" means any material event, development or change in circumstances that first occurs, arises or becomes known to the MLP Entities or the Board of Directors after the date of the Merger Agreement, to the extent that such event, development or change in circumstances was not reasonably foreseeable as of or prior to the date of the Merger Agreement; provided, however, that in no event shall the following events, developments or changes in circumstances constitute an intervening event: (i) the receipt, existence or terms of an alternative proposal or any matter relating thereto or consequence thereof, (ii) any event, development or change (A) generally affecting the United States or global economy or the financial, credit, debt, securities or other capital markets in the United States or any other jurisdiction, including changes in interest rates or currency rates or (B) in circumstances relating to Parent or Merger Sub or any of their respective affiliates, (iii) any change in laws, the interpretation thereof or political, legislative or regulatory conditions (A) applicable to any MLP Group Entity or any of their respective properties or assets or (B) generally affecting the industries in which the MLP Group Entities operate, (iv) any development or change generally affecting the industries in which the MLP Group Entities operate, (v) the entry into, or announcement of, the Merger Agreement and the Transactions, (vi) acts of war or terrorism (or the escalation of the foregoing) or natural or weather-related disasters or other force majeure events (including hurricanes, floods or earthquakes) and (vii) (A) any change in the market price or trading volume of the Common Units or (B) any MLP Group Entity meeting or exceeding internal or published projections, forecasts or revenue or earnings predictions for any period (provided, however, that the underlying causes of such change or result will not be excluded by this clause (vii), except to the extent such underlying causes are otherwise excluded pursuant to any of the foregoing clauses (i) through (vi)).

        The term "superior proposal" means a bona fide alternative proposal that the Board of Directors has determined in good faith, after consultation with its outside financial and legal advisors, taking into account the various legal, financial, regulatory and other aspects of such bona fide alternative proposal, including the financing terms thereof, the nature of the consideration offered, the provisions permitting the payment of distributions by the Partnership, the expected timing and risk and likelihood of consummation (including as a consequence of the impacts of any antitrust law on such bona fide alternative proposal), (i) is reasonably likely to be consummated in accordance with its terms (provided, however, that the fact that any requisite vote or consent of the Unitholders that may be required to effect such bona fide alternative proposal has not yet been obtained shall not be taken into account in determining whether a proposal is reasonably likely to be consummated) and (ii) if consummated, would result in a transaction (i) more favorable to each of the Unitholders from a financial point of view than the Transactions (after taking into account any revisions to the terms of the Transactions proposed by Parent) and (ii) in which the value differential between the consideration to be received by the Public Unitholders in such bona fide alternative proposal and the consideration to be received by the Principal Unitholders in such bona fide alternative proposal equals the agreed merger consideration differential; provided, however, that for purposes of the definition of "superior proposal," the references to "5.0% or more" in the definition of alternative proposal shall be deemed to be references to "more than 95.0%."

Termination of the Merger Agreement

        The Merger Agreement may be terminated at any time prior to the completion of the Merger:

        The term "divestiture request" means any request or requirement, whether or not in writing (including electronic communication), by a representative of the Antitrust Division of the Department of Justice, the Bureau of Competition of the Federal Trade Commission or a representative of any comparative non-U.S. Governmental Authority that Parent, Merger Sub, any MLP Group Entity or GP Holdings (or any of their respective affiliates) offer, accept or agree, or commit to agree, to a divestiture condition with respect to one or more specific assets, contracts, businesses or lines of business as a condition to the clearance or approval of, or consent or waiver with respect to, the Transactions under antitrust laws.

Termination Fees and Expenses

        In certain circumstances, the Board of Directors has the right to terminate the Merger Agreement and withdraw its recommendation, as further described in "The Merger Agreement—No Solicitation or Withdrawal of Recommendation." In that event, the Partnership must pay the MLP Termination Fee prior to, and as a condition of, the termination. The MLP Termination Fee is also payable if Parent has terminated the Merger Agreement:

        In addition, the MLP Termination Fee is payable in the event the Merger Agreement is terminated by Parent due to the failure of either MLP Entity or GP Holdings to perform any covenant set forth in the Merger Agreement (other than the no solicitation and no withdrawal of recommendation covenants) or in the event the Merger Agreement is terminated by either the Partnership or Parent after the Outside Date at a time when the Merger Agreement is terminable by Parent due to such a failure, if, within 12 months of such termination, (i) any MLP Group Entity, GP Holdings or any of their respective affiliates enters into a definitive agreement with respect to, or shall have approved or recommended to the Partnership's limited partners or otherwise not opposed, any alternative proposal or (ii) there shall have been consummated an alternative proposal (in which case, the MLP Termination Fee would be net of any amounts paid for reimbursement of expenses as described below). For a discussion of the fee payable under specific circumstances by the Sponsors to Parent following termination of the Merger Agreement, see "Support Agreements."

Table of Contents

        Parent must pay the Parent Termination Fee to the Partnership if the Merger Agreement is terminated:

        All out-of-pocket costs and expenses incurred in connection with the Merger Agreement and the Transactions will be paid by the party incurring such cost or expenses, except that we may be required to reimburse Parent for reasonable out-of-pocket fees and expenses incurred by Parent and its affiliates in connection with the Transactions and the Merger Agreement, up to a maximum of $7,500,000, if Parent terminates the Merger Agreement because of any MLP Entity's or GP Holdings' failure to perform any covenant set forth in the Merger Agreement (other than the no solicitation and no withdrawal of recommendation covenants) or if either the Partnership or Parent terminates the Merger Agreement after the Outside Date at a time when the Merger Agreement is terminable by Parent due to such a failure.

Cooperation Regarding the Partnership's Debt

        If requested by Parent at any time after the date of the Merger Agreement, the MLP Entities and GP Holdings must, and must cause their subsidiaries to, reasonably cooperate with, and use commercially reasonable efforts to assist, Parent and Merger Sub in taking all actions necessary to: (i) effect a discharge, covenant defeasance, redemption, amendment or similar action in connection with any notes or bonds issued pursuant to our Indenture dated March 28, 2013, with respect to the 6.25% senior notes due 2020; (ii) effect any consent solicitation related to any provisions of the Indenture prior to the closing of the Merger; and (iii) contemporaneously with the closing of the Merger, repay any indebtedness on behalf of the Partnership and any subsidiaries, terminate all commitments of lenders to lend under such credit facilities and terminate or release any and all guarantees of, and liens securing, such indebtedness.

Employee Benefits

        Pursuant to the Merger Agreement, Parent has agreed, for a period of 12 months following the closing of the Merger, to provide each employee of the surviving entity, its subsidiaries and our general partner with a base salary or hourly wage that is at least equal to the base salary and hourly wage provided to such employee as of the date of the Merger Agreement. Parent has also agreed continue in effect the hourly pay practices that are applicable to the employees as of the closing date of the Merger. Beginning on the closing date of the Merger and continuing through the last day of the calendar year in which the closing of the Merger occurs, Parent has agreed to provide each employee with employee benefits pursuant to the Partnership's benefit plans in effect as of the closing date of the Merger, process payroll for employees in the same manner as processed as of the closing date of the Merger, and continue in effect policies applicable to the employees as of the closing date of the Merger. Beginning on the first day of the next calendar year, Parent has agreed to provide each

79


Table of Contents

employee with employee benefits that are substantially comparable in the aggregate to the employee benefits provided to other similarly situated employees of Parent.

        On the first payroll date following the 12-month anniversary of the closing date of the Merger, Parent has agreed to pay each employee who has remained with the surviving entity, its subsidiaries or its general partner until the date that is 12 months following the closing date of the Merger a retention bonus equal to eight weeks of the employee's then-current base salary.

        Parent has agreed to continue our 401(k) plan through the last day of the calendar year in which the closing of the Merger occurs and is to make matching contributions and profit sharing contributions determined in the same manner in the ordinary course consistent with past practice. On the last day of the calendar year in which the closing of the Merger occurs, each individual who is an employee on the closing date of the Merger will be fully vested in any account balance he or she has under our 401(k) plan on the last day of the calendar year in which the closing of the Merger occurs. Parent has agreed that it will, or will cause one of its affiliates to, take any and all actions necessary, including amending our 401(k) plan to effectuate the full vesting and to ensure that no amounts will be forfeited on an employee's termination of employment following the closing of the Merger if such employee still maintains an account balance under our 401(k) plan on the last day of the calendar year in which the closing of the Merger occurs.

Severance

        In connection with the Merger, Parent has agreed to make, or cause one of its affiliates to make, certain payments to employees of the Partnership upon a termination of employment (1) by Parent or its affiliates without cause, (2) by the employee for good reason or (3) in the case of certain of our named executive officers, upon their resignation, in any case, if such termination occurs during the period commencing on the closing date of the Merger and ending on the 12-month anniversary of the closing date (subject to the execution and non-revocation by such employee of a release). See "The Merger—Interests of Directors and Executive Officers in the Merger" for more information regarding potential severance payments to our executive officers,

Amendment, Extension and Waiver

        The parties may amend provisions of the Merger Agreement at any time, except that no amendment that requires further approval by Unitholders is permitted without the further approval of such Unitholders. All such amendments must be in writing and signed by each of the parties.

        At any time prior to the Effective Time, the parties may (i) waive any inaccuracies in the representations and warranties contained in the Merger Agreement, (ii) extend the time for the performance of any of the obligations or other acts of the other parties, or (iii) waive compliance with any of the agreements or conditions contained in the Merger Agreement, except that no waiver that requires further approval by Unitholders is permitted without the further approval of such Unitholders. Any agreement on the part of a party to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to the Merger Agreement to assert any of its rights under the Merger Agreement or otherwise does not constitute a waiver of such rights.

SUPPORT AGREEMENTS

        This section of this information statement describes the material provisions of the Support Agreements but does not purport to describe all of the terms of the Support Agreements. The following summary is qualified in its entirety by reference to the complete text of the Support Agreements, copies of which are included in Annex B to this information statement and are incorporated into this section by reference in their entireties. We urge you to read the full text of the Support Agreements.

Sponsor Support Agreements

        On May 27, 2014, the Sponsors entered into Support Agreements with Parent and Merger Sub, pursuant to which the Sponsors agreed to deliver, immediately following the execution and delivery of the Support Agreements and the Merger Agreement, a written consent approving the Merger Agreement and the Transactions.

        Each of the Sponsors has agreed that, while its Support Agreement remains in effect and except as otherwise contemplated by its Support Agreement or the Merger Agreement, such Sponsor (i) will not (A) call, or cause to be called, any special meeting of the limited partners of the Partnership or (B) take action by written consent inconsistent with the Support Agreement and (ii) will vote its Common Units, or cause its Common Units to be voted, (A) for approval of the Merger Agreement and any related proposal in furtherance thereof (including any amendment of the Merger Agreement other than an amendment adverse to the Sponsor) and (B) against: (1) any alternative proposal; (2) any action that would reasonably be expected to result in (x) a breach of or failure to perform any representation, warranty, covenant or agreement of either MLP Entity or GP Holdings under the Merger Agreement or (y) any of the conditions described in "The Merger—Conditions to the Merger" not being satisfied; (3) any change in the business or management of the MLP Entities or membership of the Board of Directors; (4) any action that would prevent or materially delay, or would reasonably be expected to prevent or materially delay, the consummation of the Merger or the GP Equity Transfer; or (5) change in any manner the distribution policy or capitalization of, including the voting rights of any partners of, the Partnership. Each Sponsor also agreed to grant Parent or Parent's designee an irrevocable proxy to vote such Sponsor's Common Units as described in this paragraph. The proxies terminate automatically upon the termination of the Merger Agreement.

        Further, the Sponsors have agreed not to transfer or otherwise dispose of their Common Units or any interest therein or voting rights with respect thereto while the Support Agreements remain in effect and, in certain circumstances, for one year following the termination of the Support Agreements, except that sales of Common Units by the Sponsors (i) as affiliates or (ii) to the public in registered offerings are permitted during the one-year period following the termination of the Support Agreements.

        The Sponsors have agreed that they and their respective officers, managers or directors shall not, and that they shall instruct and cause their respective affiliates and representatives not to, directly or indirectly: (i) initiate, solicit or knowingly facilitate or encourage any inquiries, discussions regarding, or the making or submission of, any proposal, request or offer that constitutes, or could reasonably be expected to lead to, any alternative proposal, (ii) approve, endorse, recommend or enter into any contract or agreement in principle, whether written or oral, with any person (other than Parent and Merger Sub) concerning any letter of intent, memorandum of understanding, acquisition agreement, merger agreement, joint venture agreement, partnership agreement or other similar contract concerning

81

an alternative proposal, (iii) terminate, amend, release, modify, or fail to enforce any provision of, or grant any permission, waiver or request under, any standstill, confidentiality or similar contract entered into by one or more of the MLP Group Entities in respect of or in contemplation of an alternative proposal, (iv) conduct, engage in, continue or otherwise participate in any discussions or negotiations regarding any alternative proposal, (v) furnish any non-public information relating to any of the MLP Group Entities, or afford access to the books or records or representatives of any of the MLP Group Entities to any third party that, to the knowledge of the MLP Entities, after consultation with its representatives, is seeking to or may make, or has made, an alternative proposal; (vi) take any action to make the provisions of any takeover laws inapplicable to any transactions contemplated by any alternative proposal or (vii) resolve or publicly propose or announce to do any of the foregoing. These restrictions do not apply to (i) the MLP Group Entities, GP Holdings and their respective subsidiaries, officers, managers, directors and representatives (each an "excepted party") or (ii) any Sponsor or any of its representatives or affiliates, if such person is taking an action at the request of any excepted party, if (A) at the time of such request, such excepted party is (1) providing information or access to the books and records of the MLP Group Entities, in accordance with the Merger Agreement, to a third party that has made a timely bona fide alternative proposal or (ii) engaging or participating in discussions or negotiations permitted by the Merger Agreement with a third party with respect to a timely bona fide acquisition proposal and (B) the action taken by the Sponsor or any of its representatives or affiliates in response to such request is consistent with and in furtherance of such actions being taken by the excepted party.

        In addition, the Sponsors have agreed to pay to Parent, upon consummation of an alternative proposal, 50% of the aggregate value realized by the Sponsors in connection with (i) permitted sales of Common Units to the public and (ii) such alternative proposal, in excess of the Sponsor Merger Consideration (up to $50,000,000), if (A) the Partnership is obligated to pay the MLP Termination Fee and (B) within 12 months following the termination of the Merger Agreement, any MLP Group Entity, GP Holdings or any of their respective affiliates has entered into an agreement with respect to, or approved or recommended to the Partnership's limited partners or otherwise not opposed, an alternative proposal.

        The Support Agreements terminate upon the earliest of (i) the mutual agreement of the parties, (ii) the consummation of the Merger and (iii) the termination of the Merger Agreement in accordance with its terms, except as otherwise described above.

Founding Unitholder Support Agreements

        On May 27, 2014, the Founding Unitholders also entered into Support Agreements with Parent and Merger Sub that are substantially similar to the Support Agreements entered into by the Sponsors, although (i) the Founding Unitholders are not obligated to pay any fee if an alternative acquisition proposal is consummated, (ii) the restrictions on transfer of Common Units owned by the Founding Unitholders do not extend beyond the termination of their Support Agreements, and (iii) the Founding Unitholders' Support Agreements do not contain any of the restrictions described under "Support Agreements—Sponsor Support Agreements—No Solicitation." The Founding Unitholders executed their Support Agreements solely in their capacity as holders of Common Units, and their Support Agreements do not limit or prohibit any Founding Unitholder's action or inaction in their capacity as an officer of the Partnership or our general partner or as a member of the Board of Directors.

Represents the period from May 4, 2012, the date on which our Common Units began trading on the NYSE, through June 30, 2012.

        The closing sale price of our Common Units on the NYSE on May 27, 2014, which was the last trading day before we announced the Merger, was $12.93 per Common Unit. On June 20, 2014, the last practicable trading day before the date of this information statement, the closing price of our Common Units on the NYSE was $14.38. You are encouraged to obtain current market quotations for our Common Units.

        We paid a cash distribution for the first quarter of 2014 of $0.37 per Common Unit. As permitted under the Merger Agreement, we expect to continue to make distributions consistent with our historical distribution policy through the closing date of the Merger. If the closing date occurs before the announced record date for any quarterly distribution, the record date for such quarterly distribution will be the business day immediately before the closing date of the Merger. It is anticipated that all Unitholders of record on the day preceding the closing date of the Merger will also receive the Merger Related Distribution, a final one-time cash distribution in connection with, and conditioned upon, the closing of the Merger, which will be declared and made in accordance with the provisions of the Merger Agreement. The Merger Related Distribution will be calculated to approximate the distribution that would have otherwise been paid for the period through the closing date of the Merger, subject to an additional reserve of $12.3 million to cover a portion of the Transaction-related costs of the Partnership.

        There is no guarantee that Unitholders will receive cash distributions from us. Our Unitholders have no contractual or other legal right to receive cash distributions from us on a quarterly or other basis. The Board of Directors has adopted a policy pursuant to which we will distribute to our Unitholders each quarter all of the available cash we generate each quarter as described above and as determined quarterly by the Board of Directors, but it may change this policy at any time.

Transfer Agent and Registrar

        The transfer agent and registrar for our Common Units is American Stock Transfer & Trust Company.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

        The following table sets forth certain information regarding the beneficial ownership of our Common Units (as of June 20, 2014, unless otherwise indicated) for the following:

        We have determined beneficial ownership in accordance with SEC rules. The information does not necessarily indicate beneficial ownership for any other purpose. Under these rules, a person is deemed to be a beneficial owner of our Common Units if that person has a right to acquire ownership within 60 days of June 20, 2014 by the exercise of vested Phantom Unit awards. A person is also deemed to be a beneficial holder of our Common Units if that person has or shares voting power, which includes the power to vote or direct the voting of our Common Units, or investment power, which includes the power to dispose of or to direct the disposition of such Common Units. Except in cases where community property laws apply or as indicated in the footnotes to this table, we believe that each Unitholder identified in the table possesses sole voting and investment power over Common Units shown as beneficially owned by the Unitholder. The percentages of beneficial ownership set forth below are based on 139,355,037 Common Units issued and outstanding as of May 27, 2014.

        Except as otherwise indicated, the business address for each person listed below is c/o PetroLogistics LP, 600 Travis Street, Suite 3250, Houston, Texas 77002.

        NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound, the Parties agree as follows:


ARTICLE I
THE MERGER; THE GP EQUITY TRANSFER

        Section 1.1    The Merger.     Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DRULPA and the DLLCA, at the Effective Time, Merger Sub will be merged with and into MLP (the "Merger"), the separate limited liability company existence of Merger Sub will cease, and MLP will continue its existence as a limited partnership under the Laws of the State of Delaware as the surviving entity in the Merger (the "Surviving Entity").

        Section 1.2    The GP Equity Transfer.     Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DLLCA, at the Effective Time, GP Holdings will transfer and deliver to Parent or an Affiliate of Parent designated by Parent, and Parent (or its designated Affiliate) will accept the transfer and delivery from GP Holdings of, the GP Equity Interest, free and clear of all Liens, except for any transfer restrictions under any applicable securities Laws (the "GP Equity Transfer").

        Section 1.3    Closing.     Subject to the provisions of Article VII, unless otherwise agreed by Parent and MLP in writing, the closing of the Transactions (the "Closing") will take place at the offices of Jones Day, 2727 North Harwood Street, Dallas, Texas 75201 at 7:30 A.M., local time, on the second Business Day after the satisfaction or waiver of the conditions set forth in Article VII (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions); provided, however, that (a) if the Closing would otherwise occur within the 10 Business Day period prior to the date on which MLP's Quarterly Report on Form 10-Q or MLP's Annual Report on Form 10-K (or any amendment to any previously filed MLP SEC Document) would be required to be filed with the SEC, the Closing will occur on the third Business Day after the filing by MLP of such report (subject, in each case, to the satisfaction or waiver of such conditions as of the date determined by this clause (a)) and (b) if the Closing would otherwise occur during the Unitholder Consent Period, the Closing will occur on the first Business Day following the expiration of such period (subject to the satisfaction or waiver of such conditions as of the date determined by this clause (b)). The date on which the Closing actually occurs is referred to as the "Closing Date."

        Section 1.4    Effects of the Merger.     Subject to the provisions of this Agreement, at the Closing, MLP will cause a certificate of merger, executed in accordance with the relevant provisions of the DRULPA and the DLLCA (the "Certificate of Merger"), to be duly filed with the Secretary of State of the State of Delaware. The Merger will become effective at such time as the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or at such later date or time as may be agreed by MLP and Parent in writing and specified in the Certificate of Merger (the effective time of the Merger (as well as the GP Equity Transfer) is referred to as the "Effective Time"). If the Secretary of State of the State of Delaware requires any changes in the Certificate of Merger as a condition to filing or issuing a certificate that the Merger is effective, the Parties shall execute any necessary revisions incorporating such changes; provided that such changes are not inconsistent with and do not result in any material changes in the terms of this Agreement.

A-2



ARTICLE II
EFFECT ON UNITS; TRANSFER OF GP EQUITY INTEREST

        Section 2.1    Effect of Merger.     Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of the MLP Entities, the Parent Entities or the holder of any securities of any of them:

A-4

The MLP Entities shall cooperate with Parent in coordinating the deduction and withholding of any Taxes required to be deducted and withheld by any MLP Group Entity under applicable Tax Law, including payroll Taxes relating to payments made in respect of Phantom Units. To the extent amounts are so withheld and paid over to the appropriate Tax authority, such withheld amounts will be treated for the purposes of this Agreement as having been paid to the Person, including the former Unitholder or former holder of Phantom Units, as applicable, in respect of whom such withholding was made.

        Section 2.6    Adjustments.     Notwithstanding any provision of this Article II to the contrary (but without in any way limiting the covenants in Section 6.2 and 6.3 or other applicable prohibitions in this Agreement), if between the date of this Agreement and the Effective Time the number of outstanding Common Units have been changed into a different number of units or a different class by reason of the occurrence or record date of any unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, combination, exchange of units or similar transaction, the Merger Related Consideration will be equitably adjusted to proportionately reflect the effect of such unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, combination, exchange of units or similar transaction and to provide the Unitholders and holders of Phantom Units the same economic effect as contemplated by this Agreement prior to such event.

        Section 2.7    No Dissenters' Rights.     No dissenters' or appraisal rights are or will be available with respect to the Transactions.

termination or cancellation under, accelerate the performance required by, or result in the creation of any Lien upon any of the respective properties or assets of, Parent or Merger Sub under any Contract to which Parent or Merger Sub is a party or by which it or any of its respective properties or assets may be bound or affected, except, in the case of clause (ii) above, for any such violation, conflict, loss, default, termination, modification, cancellation, acceleration, or creation that, individually or in the aggregate, would not reasonably be expected to result in a Parent Material Adverse Effect.

        (e)    No Litigation.     As of the date hereof, there is no Proceeding pending or, to the Knowledge of Parent or Merger Sub, threatened, against or affecting Parent or Merger Sub that would reasonably be expected to result in a Parent Material Adverse Effect.

        (f)    No Fees.     No broker, investment banker or financial advisor is entitled to any broker's, finder's or financial advisor's fee or commission, or the reimbursement of expenses, in connection with the transactions contemplated hereby based on Contracts made by or on behalf of Parent or Merger Sub.

6.    Termination.    

        (a)    Term.     The term (the "Term") of this Agreement shall commence on the date hereof and shall terminate upon the earliest of (i) the mutual agreement of the Parties, (ii) the consummation of the Closing, and (iii) the termination of the Merger Agreement in accordance with its terms. Any proxy or consent granted under this Agreement shall be effective only during the Term.

        (b)    Effect of Termination; Survival of Certain Provisions.     Upon termination of the Term, this Agreement shall terminate and become null and void and of no effect with no liability on the part of any Party hereto, provided that (i) such termination shall not relieve any Party from any liability for any breach of this Agreement prior to such termination and (ii) the provisions of this Section 6 and Sections 3(c), 7 and 8 shall survive any termination of this Agreement.

7.    Exceptions.    This Agreement is executed by the Founding Unitholders solely in their capacity as holders of the Covered Units, and notwithstanding anything to the contrary in this Agreement, and whether or not any particular provision of this Agreement refers to this Section 7, this Agreement does not in any way limit or prohibit any natural person's (including the Founding Unitholder that is a natural person) action or inaction (including with respect to an Alternative Proposal) in his or her capacity as an officer of MLP or MLP GP or member of the MLP GP Board. The Founding Unitholder that is a natural person acknowledges that: (a) he has read and understands Section 6.4 of the Merger Agreement; (b) as an officer of MLP or MLP GP or member of the MLP GP Board, he is a "MLP Non-Solicit Party" as that term is used in Section 6.4 of the Merger Agreement; (c) in Section 6.4 of the Merger Agreement, the MLP Entities and GP Holdings have agreed that (i) the MLP Non-Solicit Parties will refrain from taking certain specified actions (the "Prohibited Actions") and (ii) the MLP Non-Solicit Parties may take certain specified actions (the "Permitted Actions") only in accordance with, and subject to the satisfaction of specified conditions contained in, the provisions of Section 6.4 of the Merger Agreement; and (d) if a MLP Non-Solicity Party (i) fails to refrain from taking the Prohibited Actions or (ii) takes any Permitted Action other than in accordance with, and after satisfaction of the applicable conditions contained in, the provisions of Section 6.4 of the Merger Agreement, then (A) the MLP Entities and GP Holdings will have breached their obligations under Section 6.4 of the Merger Agreement, (B) in addition to any other remedy Parent and Merger Sub may have against the MLP Entities and GP Holdings with respect to such breach, under Section 8.1 (c)(i) of the Merger Agreement, Parent will have the right to terminate the Merger Agreement (unless such breaches are de minimis in nature and do not adversely affect Parent and Merger Sub or the Transactions), and (C) under Section 8.2(b)(i) of the Merger Agreement, upon any such termination, MLP will be obligated to pay to Parent the MLP Termination Fee. None of Parent, Merger Sub or any of their Affiliates shall assert any claim that any action taken or not taken by a Founding Unitholder,

B-1-6


or any of its Affiliates, in its capacity as an officer of MLP or MLP GP or member of the MLP GP Board violates this Agreement.

8.    Miscellaneous.    

        (a)    Entire Agreement.     This Agreement (together with Schedules I and II and Exhibit A hereto) constitutes the entire agreement, and supersedes all other prior Contracts, both written and oral, among the Parties with respect to the subject matter of this Agreement.

        (b)    Further Assurances.     Each Founding Unitholder shall execute and deliver such additional documents and take all such further lawful action as may be reasonably requested by Parent to consummate and make effective the arrangements contemplated hereby. Without limiting the foregoing, the Founding Unitholders shall execute and deliver to Parent and any of its designees any additional consents or proxies, including with respect to Additional Owned Units, reasonably requested by Parent in furtherance of this Agreement.

        (c)    No Assignment.     This Agreement shall not be assignable by operation of law or otherwise (other than (i) an assignment related to the death of a natural person so long as the assignee has agreed in writing to be bound, or is otherwise bound, by the terms of this Agreement or (ii) an assignment by a trustee to an additional or successor trustee so long as the additional or successor trustee has agreed in writing to be bound, or is otherwise bound, by the terms of this Agreement; provided, however, that each of Parent or Merger Sub may, without the consent of any of the Founding Unitholders, assign this Agreement and any of their respective rights and obligations hereunder to one or more Affiliates of Parent or Merger Sub to which rights and obligations under the Merger Agreement are assigned in accordance with the Merger Agreement, but no such assignment will relieve Parent or Merger Sub of its obligations hereunder. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns. Any purported assignment in violation of this Agreement is void.

        (d)    Binding Successors.     Without limiting any other rights Parent may have hereunder in respect of any Transfer of the Covered Units, each Founding Unitholder agrees that, except as set forth in Schedule I, this Agreement and the obligations hereunder shall attach to the Covered Units beneficially owned by such Founding Unitholder and shall be binding upon any Person to which legal or beneficial ownership of such Covered Units shall pass, whether by operation of law or otherwise, including such Founding Unitholder's heirs, guardians, administrators, representatives or successors. Each Person named, designated or acting as a proxy or attorney-in-fact under Section 1(c)(i) shall be subject to and bound by the terms and provisions of this Agreement.

        (e)    Modification or Amendments.     Subject to the provisions of applicable Law, the Parties may modify or amend this Agreement only by written agreement executed and delivered by the Parties.

        (f)    FIRPTA Certificate.     At the Closing, each Founding Unitholder that is a natural person will deliver to Parent a certificate, dated as of the Closing Date and substantially in the form and to the effect of Exhibit C to the Merger Agreement, which satisfies the requirements set forth in Treasury Regulation Section 1.1445-2(b)(2), attesting that such Founding Unitholder is not a "foreign person" for U.S. federal income Tax purposes.

        (g)    Notices.     All notices, requests, permissions, waivers and other communications hereunder will be in writing and will be deemed to have been duly given (i) when sent, if sent by facsimile or electronic mail (.pdf), (ii) when delivered, if delivered personally to the intended recipient and (iii) one Business Day following sending by overnight delivery via an international courier service and, in each case, addressed to a Party at the following address for such Party (or to such other address as will be

B-1-7


furnished in writing by any such Party to the other Parties in accordance with the provisions of this Section 8(g)):

        (h)    Severability.     The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (i) a suitable and equitable provision will be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (ii) the remainder of this Agreement and the application of such provision to other Persons or circumstances will not be affected by such invalidity or unenforceability. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

        (i)    Remedies.     The Parties agree that irreparable damage would occur and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and it is accordingly agreed that the Parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 8(i) in the Delaware Court of Chancery or any federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief as provided herein on the basis that (i) either Party has an adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any

B-1-8


reason at law or equity. Each Party further agrees that no Party will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 8(i), and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

        (j)    No Waiver.     The failure of or delay by any Party in exercising any right hereunder will not operate as a waiver thereof nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a Party to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such Party.

        (k)    No Third Party Beneficiaries.     This Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties and, consequently, may not accurately characterize actual facts or circumstances.

        (l)    Governing Law.     This Agreement and all claims or causes of action (whether in contract, tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement) will be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to Contracts executed in and to be performed entirely within that State.

        (m)    Submission to Jurisdiction.     By execution and delivery of this Agreement, each Party irrevocably agrees that any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other Party hereto or its successors or assigns, will be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the Parties hereby irrevocably submits with regard to any such Proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated hereby in any court other than the aforesaid courts. Each of the Parties hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any such Proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 8(m), (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) such Proceeding in such court is brought in an inconvenient forum, (y) the venue of such Proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

        (n)    Waiver of Jury Trial.     EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE

B-1-9


COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8(n).

        (p)    Counterparts.     This Agreement may be executed in counterparts (each of which will be deemed to be an original but all of which taken together will constitute one and the same agreement) and will become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties.

The Founding Unitholders, Parent and Merger Sub are sometimes referred to individually as a "Party" and collectively as the "Parties."


RECITALS

        A.    Parent, Merger Sub, PetroLogistics LP, a Delaware limited partnership ("MLP"), PetroLogistics GP LLC, a Delaware limited liability company ("MLP GP"), and Propylene Holdings LLC, a Delaware limited liability company ("GP Holdings"), have entered into an Agreement and Plan of Merger and Membership Interest Transfer Agreement, dated as of May 27, 2014 (as the same may be amended or otherwise modified from time to time by any amendment or modification thereto that is not an Adverse Amendment, the "Merger Agreement"), providing, among other things, for the merger of Merger Sub with and into MLP and the transfer by GP Holdings to Parent or one or more of its Affiliates of 100% of the membership interests of MLP GP.

        B.    On the date of this Agreement, each of the Founding Unitholders is the record and beneficial owner of the number of Common Units set forth opposite such Founding Unitholder's name on Schedule I hereto as set forth therein (the "Disclosed Owned Units").

        NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement and in the Merger Agreement, and intending to be legally bound hereby, the Parties agree as follows:

1.    Unitholder Consent; Voting; Proxy    

        (a)    Unitholder Consent.    Each of the Founding Unitholders hereby agrees that, immediately following the execution and delivery of this Agreement and the Merger Agreement, such Founding Unitholder will execute and deliver to MLP a written consent in the form attached as Exhibit A hereto (the "Unitholder Consent"). The Unitholder Consent shall be irrevocable, except as otherwise provided therein.

        (b)    Voting.    Each Founding Unitholder hereby agrees that, except as otherwise contemplated by this Agreement or the Merger Agreement, (i) such Founding Unitholder shall not as the holder of its Covered Units (A) call, or join with other Unitholders to call, any special meeting of the Limited Partners or (B) take action by written consent inconsistent with this Agreement or (ii) at any meeting of the Limited Partners at which any of the matters described below in this clause (ii) are to be voted on, however called, or at any adjournment thereof, or in any circumstance in which the vote, consent or other approval of the Limited Partners is sought for such matters, such Founding Unitholder as the holder of its Covered Units, if it is entitled to do so, shall appear at each such meeting or otherwise cause all of its Covered Units to be counted as present thereat for purposes of calculating a quorum and shall vote its Covered Units, or cause its Covered Units to be voted, (A) for approval of the Merger Agreement and any related proposal in furtherance thereof (including any proposal relating to an amendment of the Merger Agreement contemplated by Section 6.4(d) thereof but excluding any Adverse Amendment) and (B) against: (1) any Alternative Proposal; (2) any action that would reasonably be expected to result in (x) a breach of or failure to perform any representation, warranty, covenant or agreement of either MLP Entity or GP Holdings under the Merger Agreement, or (y) any of the conditions set forth in Article VII of the Merger Agreement not being satisfied; (3) any change in the business or management of MLP or MLP GP or membership of the MLP GP Board (other than with respect to the transactions contemplated in the Merger Agreement); (4) any action that would

B-2-1


prevent or materially delay, or would reasonably be expected to prevent or materially delay, the consummation of the Merger or the GP Equity Transfer; or (5) except as contemplated by the Merger Agreement, change in any manner the distribution policy or capitalization of, including the voting rights of any partners of, MLP. No Founding Unitholder shall take or agree to take any action as a Unitholder which it has agreed not to take in Section 1(a) and this Section 1(b).

        (c)    Irrevocable Proxy.    

        (d)    Adverse Amendment.    Notwithstanding anything to the contrary herein:

B-2-2


2.    No Disposition or Adverse Act.    Each Founding Unitholder hereby covenants and agrees severally and not jointly that, except as contemplated by this Agreement and the Merger Agreement, such Founding Unitholder shall not, without the prior written consent of Parent, during the Term (a) offer to Transfer (as defined in Section 8(t) below), Transfer or consent to any Transfer of any or all of the Covered Units (as defined in Section 8(t) below) or any interest therein, (b) enter into any Contract, including any option, with respect to any Transfer of any or all of the Covered Units or any interest therein, (c) grant any proxy, power-of-attorney or other authorization or consent or execute any written consent in or with respect to any or all of the Covered Units (other than (i) the Unitholder Consent and (ii) any proxy, power-of-attorney or other authorization that is (A) revocable and (B) directs the holder or grantee thereof to vote the Covered Units in accordance with this Agreement), with any such proxy, power-of-attorney or authorization purported to be granted by such Founding Unitholder being void ab initio, or (d) deposit any or all of the Covered Units into a voting trust or enter into a voting agreement or arrangement with respect to any or all of the Covered Units. Notwithstanding anything to the contrary herein, each Founding Unitholder may Transfer up to an aggregate of 150,000 of its Covered Units to the other Founding Unitholder (any such Transfer being referred to herein as a "Permitted Transfer"), and, when so Transferred, such Covered Units will become Covered Units of the transferee Founding Unitholder. Any attempted Transfer of Covered Units or any interest therein in violation of this Section 2 shall be null and void.

3.    Additional Agreements.    

        (a)    Certain Events.    In the event of any unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, combination, exchange of units or similar transaction or other change in the capital structure of MLP affecting the Covered Units or the acquisition of Additional Owned Units (as defined in Section 8(t) below) by a Founding Unitholder, (i) the type and number of Covered Units owned by such Founding Unitholder shall be adjusted appropriately to reflect the effect of such occurrence and (ii) this Agreement and the obligations hereunder shall automatically attach to any additional Covered Units issued to or acquired by such Founding Unitholder.

        (b)    Stop Transfer.    In furtherance of this Agreement, each Founding Unitholder hereby authorizes and instructs MLP (including through MLP's transfer agent) to enter a stop transfer order with respect to any Transfer of the Covered Units owned by such Founding Unitholder (other than Permitted Transfers). Each Founding Unitholder agrees that it will request MLP, as promptly as practicable after the date of this Agreement, to make a notation on its records and give instructions to the transfer agent for the Covered Units not to permit, during the Term, any Transfer of the Covered Units owned by such Founding Unitholder (other than Permitted Transfers).

        (c)    Commencement or Participation in Actions.    Each Founding Unitholder hereby agrees not to, as a Unitholder, commence or participate in, and to take, as a Unitholder, all actions necessary and effective to opt out of any class (if opting out is permitted) in any class action with respect to, any Transaction Litigation, including any claim (i) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Merger Agreement or (ii) alleging a breach of any duty of MLP GP, in its capacity as general partner of MLP, or the MLP GP Board in connection with this Agreement or the Merger Agreement or the transactions contemplated hereby or thereby; provided, however, that each Founding Unitholder shall be permitted as a Founding Unitholder or in any other capacity, to (A) participate in Transaction Litigation to defend itself or (B) commence a Proceeding, as part of pending Transaction Litigation or otherwise, to enforce its rights under this Agreement. If any Founding Unitholder is for any reason unable to opt out of a class with respect to any Transaction Litigation and receives any consideration (for the avoidance of doubt, excluding any consideration received from the Paying Agent under the Merger Agreement) from any Person in connection with or as a result of such Transaction Litigation, such Founding Unitholder will pay all of such consideration to Parent by wire transfer of immediately available funds promptly (and, in any

B-2-3


event, within five Business Days) following the later to occur of (A) the Closing Date and (B) the date on which such Founding Unitholder receives such consideration.

        (d)    Additional Owned Units.     Each Founding Unitholder hereby agrees to notify Parent promptly in writing of the number and description of any Additional Owned Units.

        (e)    Related Party Transactions.     In connection with the Closing, each Founding Unitholder that is a natural person shall, and shall cause its controlled Affiliates to, take such actions as are necessary or required on its part for the termination of each Contract with any of the MLP Group Entities set forth on Schedule II hereto, effective at the Closing, and agrees that the MLP Group Entities shall have no further liabilities or obligations to such Founding Unitholder or Affiliates thereunder from and after the Closing.

        (f)    Certain Instructions.     From time to time as appropriate, the Founding Unitholder that is a natural person will provide or cause to be provided written instructions to the Founding Unitholder that is a trustee to perform such trustee's obligations as a Founding Unitholder hereunder.

4.    Representations and Warranties of the Founding Unitholders.    The Founding Unitholders severally and not jointly represent and warrant to Parent and Merger Sub as follows:

        (a)    Title.     On the date hereof, except as set forth on Schedule I hereto, (i) such Founding Unitholder is the sole record and beneficial owner of the Disclosed Owned Units set forth opposite its name on Schedule I hereto, (ii) such Disclosed Owned Units constitute all of the Equity Securities in MLP owned of record or beneficially by such Founding Unitholder and (iii) such Founding Unitholder has sole voting power and sole power of disposition and sole power to issue instructions with respect to the matters set forth in Sections 2 and 3 hereof and all other matters set forth in this Agreement, in each case with respect to all of the Covered Units set forth opposite its name on Schedule I hereto and with no limitations, qualifications or restrictions on such rights, subject to applicable securities Laws and the terms of this Agreement and the MLP Partnership Agreement. Except as permitted or required by this Agreement or the Merger Agreement, and except as set forth on Schedule I hereto, the Covered Units of such Founding Unitholder are now, and at all times during the Term will be, held by a Founding Unitholder, free and clear of any and all Liens (other than under applicable securities Laws and as created by this Agreement and the MLP Partnership Agreement).

        (b)    Organization and Qualification.     Each Founding Unitholder that is not a natural person is a legal entity duly formed or organized (as applicable), validly existing and in good standing under the Laws of the jurisdiction in which it is formed or organized, as applicable.

        (a)    Term.     The term (the "Term") of this Agreement shall commence on the date hereof and shall terminate upon the earliest of (i) the mutual agreement of the Parties, (ii) the consummation of the Closing, and (iii) the termination of the Merger Agreement in accordance with its terms.

        (b)    Effect of Termination; Survival of Certain Provisions.     Upon termination of the Term, this Agreement shall terminate and become null and void and of no effect with no liability on the part of any Party hereto, provided that (i) such termination shall not relieve any Party from any liability for any breach of this Agreement prior to such termination and (ii) the provisions of this Section 6 and Sections 3(c), 7 and 8 shall survive any termination of this Agreement.

7.    Exceptions.    This Agreement is executed by the Founding Unitholders solely in their capacity as holders of the Covered Units, and notwithstanding anything to the contrary in this Agreement, and whether or not any particular provision of this Agreement refers to this Section 7, this Agreement does not in any way limit or prohibit any natural person's (including the Founding Unitholder that is a natural person) action or inaction (including with respect to an Alternative Proposal) in his or her capacity as an officer of MLP or MLP GP or member of the MLP GP Board. The Founding Unitholder that is a natural person acknowledges that: (a) he has read and understands Section 6.4 of the Merger Agreement; (b) as an officer of MLP or MLP GP or member of the MLP GP Board, he is a "MLP Non-Solicit Party" as that term is used in Section 6.4 of the Merger Agreement; (c) in Section 6.4 of the Merger Agreement, the MLP Entities and GP Holdings have agreed that (i) the MLP Non-Solicit Parties will refrain from taking certain specified actions (the "Prohibited Actions") and (ii) the MLP Non-Solicit Parties may take certain specified actions (the "Permitted Actions") only in accordance with, and subject to the satisfaction of specified conditions contained in, the provisions of Section 6.4 of the Merger Agreement; and (d) if a MLP Non-Solicity Party (i) fails to refrain from taking the Prohibited Actions or (ii) takes any Permitted Action other than in accordance with, and

B-2-6


after satisfaction of the applicable conditions contained in, the provisions of Section 6.4 of the Merger Agreement, then (A) the MLP Entities and GP Holdings will have breached their obligations under Section 6.4 of the Merger Agreement, (B) in addition to any other remedy Parent and Merger Sub may have against the MLP Entities and GP Holdings with respect to such breach, under Section 8.1 (c)(i) of the Merger Agreement, Parent will have the right to terminate the Merger Agreement (unless such breaches are de minimis in nature and do not adversely affect Parent and Merger Sub or the Transactions), and (C) under Section 8.2(b)(i) of the Merger Agreement, upon any such termination, MLP will be obligated to pay to Parent the MLP Termination Fee. None of Parent, Merger Sub or any of their Affiliates shall assert any claim that any action taken or not taken by a Founding Unitholder, or any of its Affiliates, in its capacity as an officer of MLP or MLP GP or member of the MLP GP Board violates this Agreement. Additionally, (i) the Founding Unitholder that is a trustee executes this Agreement solely in its capacity as such, and notwithstanding anything to the contrary in this Agreement, and whether or not any particular provision of this Agreement refers to this Section 7, its representations, warranties, covenants and agreements herein and the other provisions hereof relate to it only as such trustee, and not as trustee of any other trust, or for itself or in any corporate, individual, institutional, representative or other capacity, and relate only to the Covered Units owned by it of record as such trustee, and not with respect to any Common Units held or owned of record or beneficially as trustee of any other trust, or by it for itself or any Affiliate or in any other corporate, individual, institutional, representative or other capacity, and (ii) none of Parent, Merger Sub or any of their Affiliates shall assert any claim that any action taken or not taken by such Founding Unitholder in any other such capacity, or any of its Affiliates, violates this Agreement.

8.    Miscellaneous.    

        (a)    Entire Agreement.     This Agreement (together with Schedules I and II and Exhibit A hereto) constitutes the entire agreement, and supersedes all other prior Contracts, both written and oral, among the Parties with respect to the subject matter of this Agreement.

        (b)    Further Assurances.     Each Founding Unitholder shall execute and deliver such additional documents and take all such further lawful action as may be reasonably requested by Parent to consummate and make effective the arrangements contemplated hereby. Without limiting the foregoing, the Founding Unitholders shall execute and deliver to Parent and any of its designees any additional consents or proxies, including with respect to Additional Owned Units, reasonably requested by Parent in furtherance of this Agreement.

        (c)    No Assignment.     This Agreement shall not be assignable by operation of law or otherwise (other than (i) an assignment related to the death of a natural person so long as the assignee has agreed in writing to be bound, or is otherwise bound, by the terms of this Agreement or (ii) an assignment by a trustee to an additional or successor trustee so long as the additional or successor trustee has agreed in writing to be bound, or is otherwise bound, by the terms of this Agreement; provided, however, that each of Parent or Merger Sub may, without the consent of any of the Founding Unitholders, assign this Agreement and any of their respective rights and obligations hereunder to one or more Affiliates of Parent or Merger Sub to which rights and obligations under the Merger Agreement are assigned in accordance with the Merger Agreement, but no such assignment will relieve Parent or Merger Sub of its obligations hereunder. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns. Any purported assignment in violation of this Agreement is void.

        (d)    Binding Successors.     Without limiting any other rights Parent may have hereunder in respect of any Transfer of the Covered Units, each Founding Unitholder agrees that, except as set forth in Schedule I, this Agreement and the obligations hereunder shall attach to the Covered Units beneficially owned by such Founding Unitholder and shall be binding upon any Person to which legal or beneficial ownership of such Covered Units shall pass, whether by operation of law or otherwise, including such

B-2-7


Founding Unitholder's heirs, guardians, administrators, representatives or successors. Each Person named, designated or acting as a proxy or attorney-in-fact under Section 1(c)(i) shall be subject to and bound by the terms and provisions of this Agreement.

        (e)    Modification or Amendments.     Subject to the provisions of applicable Law, the Parties may modify or amend this Agreement only by written agreement executed and delivered by the Parties.

        (f)    FIRPTA Certificate.     At the Closing, each Founding Unitholder that is a natural person will deliver to Parent a certificate, dated as of the Closing Date and substantially in the form and to the effect of Exhibit C to the Merger Agreement, which satisfies the requirements set forth in Treasury Regulation Section 1.1445-2(b)(2), attesting that such Founding Unitholder is not a "foreign person" for U.S. federal income Tax purposes.

        (g)    Notices.     All notices, requests, permissions, waivers and other communications hereunder will be in writing and will be deemed to have been duly given (i) when sent, if sent by facsimile or electronic mail (.pdf), (ii) when delivered, if delivered personally to the intended recipient and (iii) one Business Day following sending by overnight delivery via an international courier service and, in each case, addressed to a Party at the following address for such Party (or to such other address as will be furnished in writing by any such Party to the other Parties in accordance with the provisions of this Section 8(g)):

        (h)    Severability.     The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (i) a suitable and equitable provision will be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (ii) the remainder of this Agreement and the application of such

B-2-8


provision to other Persons or circumstances will not be affected by such invalidity or unenforceability. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

        (i)    Remedies.     The Parties agree that irreparable damage would occur and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and it is accordingly agreed that the Parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 8(i) in the Delaware Court of Chancery or any federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief as provided herein on the basis that (i) either Party has an adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or equity. Each Party further agrees that no Party will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 8(i), and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

        (j)    No Waiver.     The failure of or delay by any Party in exercising any right hereunder will not operate as a waiver thereof nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a Party to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such Party.

        (k)    No Third Party Beneficiaries.     This Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties and, consequently, may not accurately characterize actual facts or circumstances.

        (l)    Governing Law.     This Agreement and all claims or causes of action (whether in contract, tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement) will be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to Contracts executed in and to be performed entirely within that State.

        (m)    Submission to Jurisdiction.     By execution and delivery of this Agreement, each Party irrevocably agrees that any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other Party hereto or its successors or assigns, will be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the Parties hereby irrevocably submits with regard to any such Proceeding for itself and in

B-2-9


respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated hereby in any court other than the aforesaid courts. Each of the Parties hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any such Proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 8(m), (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) such Proceeding in such court is brought in an inconvenient forum, (y) the venue of such Proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

        (n)    Waiver of Jury Trial.     EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8(n).

Except as otherwise expressly provided elsewhere in this Agreement, any provision herein which contemplates the agreement, approval or consent of, or exercise of any right of, a Party, such Party may give or withhold such agreement, approval or consent, or exercise such right, in its sole and absolute discretion, the Parties hereby expressly disclaiming any implied duty of good faith and fair dealing or similar concept.

6.    Termination.    

        (a)    Term.     The term (the "Term") of this Agreement shall commence on the date hereof and shall terminate upon the earliest of (i) the mutual agreement of the Parties, (ii) the consummation of the Closing and (iii) the termination of the Merger Agreement in accordance with its terms; provided that nothing herein shall relieve any Party from liability for any breach of this Agreement prior to its termination.

        (b)    Continuation of Transfer Restriction.     Section 2(a) shall survive any termination of this Agreement until the earlier of (i) such time as it is no longer possible for the Sponsor Termination Fee to become payable under the terms of Section 3(g) or (ii) the Fee Payment Due Date. Notwithstanding anything to the contrary herein (including in Section 2(a)), during the period following the Term during which Section 2(a) continues to survive, a Sponsor Entity may, without the consent of Parent, (A) grant a consent or execute any written consent in or with respect to any or all of the Covered Units, or otherwise enter into a Contract to Transfer Covered Units, in support of an Alternative Proposal,

B-3-9


(B) Transfer its Covered Units to one or more of its Affiliates, provided that any such transferee agrees in writing, in a form reasonably acceptable to Parent, to be bound by the provisions hereof as a "Sponsor Entity" hereunder and provided, further, that no such Transfer will relieve the transferor of any of its obligations with respect to the Sponsor Termination Fee, or (C) if the only circumstances in which the Sponsor Termination Fee may become payable pursuant to Section 3(g)(i) are those contemplated by Section 8.2(b)(iii) of the Merger Agreement, Transfer its Covered Units to any other Person by means of Public Sales, so long as such Public Sales are not intended to effect a transaction that would otherwise constitute the consummation of an Alternative Proposal.

        (c)    Survival of Certain Provisions.     Section 3(c), Section 3(g), this Section 6 and Section 7 shall survive any termination of this Agreement.

7.    Miscellaneous.    

        (a)    Entire Agreement.     This Agreement (together with Schedules I and II and Exhibit A hereto) constitutes the entire agreement, and supersedes all other prior Contracts, both written and oral, among the Parties with respect to the subject matter of this Agreement.

        (b)    Reasonable Efforts.     Subject to the terms and conditions of this Agreement, each Party agrees to use all reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary or desirable under applicable Laws to consummate and make effective the arrangements contemplated hereby. Upon Parent's request and without further consideration, each Sponsor Entity shall execute and deliver such additional documents and take all such further lawful action as may be necessary or desirable to consummate and make effective, in the most expeditious manner practicable, the arrangements contemplated hereby. Without limiting the foregoing, the Sponsor Entities shall execute and deliver to Parent and any of its designees any additional consents or proxies, including with respect to Additional Owned Units, reasonably requested by Parent in furtherance of this Agreement.

        (c)    No Assignment.     This Agreement shall not be assignable by operation of law or otherwise; provided, however, that each of Parent or Merger Sub may, without the consent of any of the Sponsor Entities, assign this Agreement and any of their respective rights and obligations hereunder to one or more Affiliates of Parent or Merger Sub to which rights and obligations under the Merger Agreement are assigned in accordance with the Merger Agreement. Any purported assignment in violation of this Agreement is void.

        (d)    Binding Successors.     Without limiting any other rights Parent may have hereunder in respect of any Transfer of the Covered Units, each Sponsor Entity agrees that this Agreement and the obligations hereunder shall attach to the Covered Units beneficially owned by such Sponsor Entity and shall be binding upon any Person to which legal or beneficial ownership of such Covered Units shall pass, whether by operation of law or otherwise; provided that this Section 7(d) shall not apply to any Person to which legal or beneficial ownership of any Covered Unit passes as contemplated by clause (C) of the last sentence of Section 6(b).

        (e)    Modification or Amendments.     Subject to the provisions of applicable Law, the Parties may modify or amend this Agreement only by written agreement executed and delivered by duly authorized officers of the respective Parties.

        (f)    Tax Consequences.     The Parties acknowledge that the Disaggregation Transfers will constitute a "transfer" pursuant to Section 708(b) of the Code, and shall treat the transfers consistently as such for all income Tax purposes.

        (g)    FIRPTA Certificate.     At the Closing, each Sponsor Entity will deliver to Parent a certificate, dated as of the Closing Date and substantially in the form and to the effect of Exhibit C to the Merger

B-3-10


Agreement, which satisfies the requirements set forth in Treasury Regulation Section 1.1445-2(b)(2), attesting that such Person is not a "foreign person" for U.S. federal income Tax purposes.

        (h)    Notices.     All notices, requests, permissions, waivers and other communications hereunder will be in writing and will be deemed to have been duly given (a) when sent, if sent by facsimile or electronic mail (.pdf), (b) when delivered, if delivered personally to the intended recipient and (c) one Business Day following sending by overnight delivery via an international courier service and, in each case, addressed to a Party at the following address for such Party (or to such other address as will be furnished in writing by any such Party to the other Parties in accordance with the provisions of this Section 7(h)):

        (i)    Severability.     The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision will be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances will not be affected by such invalidity or unenforceability, nor will such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

        (j)    Remedies.     The Parties agree that irreparable damage would occur and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were

B-3-11


not performed in accordance with their specific terms or were otherwise breached, and it is accordingly agreed that the Parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 7(j) in the Delaware Court of Chancery or any federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief as provided herein on the basis that (a) either Party has an adequate remedy at law or (b) an award of specific performance is not an appropriate remedy for any reason at law or equity. Each Party further agrees that no Party will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 7(j), and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. If Parent commences a Proceeding to enforce its rights under this Agreement to collect the Sponsor Termination Fee or other amounts payable pursuant to Section 3(g), and such Proceeding results in an Order against any Sponsor Entity, the Sponsor Entities shall pay to Parent the costs and expenses (including reasonable and documented attorney's fees and expenses) incurred by Parent and its Affiliates in connection with such Proceeding. The Sponsor Entities shall be jointly and severally liable for any such payment.

        (k)    No Waiver.     The failure of or delay by any Party in exercising any right hereunder will not operate as a waiver thereof nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a Party to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such Party.

        (l)    No Third Party Beneficiaries.     This Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

        (m)    Governing Law.     This Agreement and all claims or causes of action (whether in contract, tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement) will be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to Contracts executed in and to be performed entirely within that State.

        (n)    Submission to Jurisdiction.     By execution and delivery of this Agreement, each Party irrevocably agrees that any Proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other Party hereto or its successors or assigns, will be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the Parties hereby irrevocably submits with regard to any such Proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions

B-3-12


contemplated hereby in any court other than the aforesaid courts. Each of the Parties hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any Proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 7(n), (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) the Proceeding in such court is brought in an inconvenient forum, (y) the venue of such Proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

        (o)    Waiver of Jury Trial.     EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7(o).

        (q)    Counterparts.     This Agreement may be executed in counterparts (each of which will be deemed to be an original but all of which taken together will constitute one and the same agreement) and will become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties.

SUPPORT AGREEMENT

        This SUPPORT AGREEMENT (this "Agreement"), dated as of May 27, 2014, is entered into by and among YSOF Propylene Investor, LLC, a Delaware limited liability company ("Sponsor Aggregator") the entities listed under the heading "Sponsor Funds" on Schedule I hereto (the "Sponsor Funds" and collectively with Sponsor Aggregator, the "Sponsor Entities"), LG Propylene LLC, a Delaware limited liability company ("Sponsor Representative") Flint Hills Resources, LLC, a Delaware limited liability company ("Parent"), and FHR Propylene, LLC, a Delaware limited liability company and Subsidiary of Parent ("Merger Sub"). The Sponsor Entities, Sponsor Representative, Parent and Merger Sub are sometimes referred to individually as a "Party" and collectively as the "Parties."


RECITALS

        A.    Parent, Merger Sub, PetroLogistics LP, a Delaware limited partnership ("MLP"), PetroLogistics GP LLC, a Delaware limited liability company ("MLP GP"), and Propylene Holdings LLC, a Delaware limited liability company ("GP Holdings"), have entered into an Agreement and Plan of Merger and Membership Interest Transfer Agreement, dated as of May 27, 2014 (as the same may be amended or otherwise modified from time to time by any amendment or modification thereto that is not an Adverse Amendment, the "Merger Agreement"), providing, among other things, for the merger of Merger Sub with and into MLP and the transfer by GP Holdings to Parent or one or more of its Affiliates of 100% of the membership interests of MLP GP.

        B.    On the date of this Agreement, Sponsor Aggregator is the record and beneficial owner of 17,422,701 Common Units (the "Disclosed Owned Units"), constituting 12.5% of the outstanding Common Units.

        C.    It is contemplated that, immediately prior to the Effective Time, Sponsor Aggregator will Transfer all Common Units owned by it on the date of this Agreement to the Sponsor Funds (or investors therein), such that as of immediately prior to the Effective Time, each of the Sponsor Funds (or investors therein) will own of record the number of such Common Units set forth opposite its name on Schedule I hereto (the "Disaggregation Transfers").

        NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement and in the Merger Agreement, and intending to be legally bound hereby, the Parties agree as follows:

1.    Unitholder Consent; Voting; Proxy.    

        (a)    Unitholder Consent.    Sponsor Aggregator hereby agrees that, immediately following the execution and delivery of this Agreement and the Merger Agreement and prior to any Disaggregation Transfers, Sponsor Aggregator will execute and deliver to MLP a written consent in the form attached as Exhibit A hereto (the "Unitholder Consent"). The Unitholder Consent shall be irrevocable, except as otherwise provided therein.

        (b)    Voting.    Each Sponsor Entity hereby agrees that, except as otherwise contemplated by this Agreement or the Merger Agreement, (i) such Sponsor Entity shall not (A) call, or cause MLP, MLP GP or the MLP GP Board to call, any special meeting of the Limited Partners or (B) take action by written consent inconsistent with this Agreement and (ii) at any meeting of the Limited Partners, however called, or at any adjournment thereof, or in any circumstance in which the vote, consent or other approval of the Limited Partners is sought, such Sponsor Entity, if it is entitled to do so, shall appear at each such meeting or otherwise cause all of its Common Units to be counted as present thereat for purposes of calculating a quorum and shall vote its Common Units, or cause its Common Units to be voted, (A) for approval of the Merger Agreement and any related proposal in furtherance

B-4-1


thereof (including any proposal relating to an amendment of the Merger Agreement contemplated by Section 6.4(d) thereof but excluding any Adverse Amendment) and (B) against: (1) any Alternative Proposal; (2) any action that would reasonably be expected to result in (x) a breach of or failure to perform any representation, warranty, covenant or agreement of either MLP Entity or GP Holdings under the Merger Agreement or (y) any of the conditions set forth in Article VII of the Merger Agreement not being satisfied; (3) any change in the business or management of MLP or MLP GP or membership of the MLP GP Board (other than with respect to the transactions contemplated in the Merger Agreement); (4) any action that would prevent or materially delay, or would reasonably be expected to prevent or materially delay, the consummation of the Merger or the GP Equity Transfer; or (5) except as contemplated by the Merger Agreement, change in any manner the distribution policy or capitalization of, including the voting rights of any Partners of, MLP. No Sponsor Entity shall take or agree to take any action which it has agreed not to take in Section 1(a) and this Section 1(b).

        (c)    Irrevocable Proxy.    

        (d)    Adverse Amendment.    Notwithstanding anything to the contrary herein:

B-4-2


2.    No Disposition or Solicitation.    

        (a)    No Disposition or Adverse Act.    Each Sponsor Entity hereby covenants and agrees that, except as contemplated by this Agreement and the Merger Agreement, such Sponsor Entity shall not, without the prior written consent of Parent, (i) offer to Transfer (as defined in Section 7(u) below), Transfer or consent to any Transfer of any or all of the Covered Units (as defined in Section 7(u) below) or any interest therein, (ii) enter into any Contract, including any option, with respect to any Transfer of any or all of the Covered Units or any interest therein, (iii) grant any proxy, power-of-attorney or other authorization or consent or execute any written consent in or with respect to any or all of the Covered Units (other than (A) the Unitholder Consent and (B) any proxy, power-of-attorney or other authorization that is (x) revocable and (y) directs the holder or grantee thereof to vote the Covered Units in accordance with this Agreement), with any such proxy, power-of-attorney or authorization purported to be granted by any Sponsor Entity being void ab initio, or (iv) deposit any or all of the Covered Units into a voting trust or enter into a voting agreement or arrangement with respect to any or all of the Covered Units. Any attempted Transfer of Covered Units or any interest therein in violation of this Section 2(a) shall be null and void.

        (b)    No Solicitation, Discussion or Negotiation.    Subject to Section 2(d), each Sponsor Entity hereby agrees that such Sponsor Entity shall not, and shall instruct and cause its Representatives and Affiliates not to, directly or indirectly:

        (c)    Disaggregation Transfers.    Immediately prior to the Effective Time (and in no event sooner), Sponsor Aggregator shall Transfer the Covered Units owned by it on the date of this Agreement to the

B-4-3


Sponsor Funds (or investors therein), such that as of immediately prior to the Effective Time, each of the Sponsor Funds (or investors therein) will own the number of such Covered Units set forth opposite its name on Schedule I hereto. Any acquisition of Additional Owned Units by the Sponsor Entities prior to the Effective Time shall be made by Sponsor Aggregator and shall be designated as being for the benefit of a Sponsor Fund, and immediately prior to the Effective Time Sponsor Aggregator shall Transfer such Additional Owned Units to the Sponsor Fund so designated (or investors therein).

        (d)    Exceptions.    Section 2(b) shall not (i) apply to any Excepted Party, (ii) require any Sponsor Entity to instruct or cause any Excepted Party to take or refrain from taking any action or (iii) prohibit any Sponsor Entity or any of its Representatives or Affiliates from taking any action at the request of any Excepted Party if (A) at the time of such request, such Excepted Party is taking actions in reliance on Section 6.4(a)(ii) of the Merger Agreement and (B) the action taken by the Sponsor Entity or any of its Representatives or Affiliates in response to such request is consistent with and in furtherance of such actions being taken by the Excepted Party.

3.    Additional Agreements.    

        (a)    Certain Events.    In the event of any unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, combination, exchange of units or similar transaction or other change in the capital structure of MLP affecting the Covered Units or the acquisition of Additional Owned Units (as defined in Section 7(u) below) by a Sponsor Entity, (i) the type and number of Covered Units shall be adjusted appropriately to reflect the effect of such occurrence, and (ii) this Agreement and the obligations hereunder shall automatically attach to any additional Covered Units issued to or acquired by such Sponsor Entity.

        (b)    Stop Transfer.    In furtherance of this Agreement, each Sponsor Entity hereby authorizes and instructs MLP (including through MLP's transfer agent) to enter a stop transfer order with respect to all of the Covered Units. Each Sponsor Entity agrees that it will request MLP, as promptly as practicable after the date of this Agreement, to make a notation on its records and give instructions to the transfer agent for the Covered Units not to permit, so long as a restriction on Transfer under Section 2(a) remains in effect, any Transfer of the Covered Units other than as expressly contemplated by this Agreement.

        (c)    Commencement or Participation in Actions.    Each Sponsor Entity hereby agrees not to commence or participate in, and to take all actions necessary and effective to opt out of any class in any class action with respect to, any Transaction Litigation, including any claim (i) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Merger Agreement or (ii) alleging a breach of any duty of MLP GP, in its capacity as general partner of MLP, or the MLP GP Board in connection with this Agreement or the Merger Agreement or the transactions contemplated hereby or thereby. If, notwithstanding compliance with the immediately preceding sentence, any Sponsor Entity is unable to opt out of a class with respect to any Transaction Litigation and receives any consideration from any Person in connection with or as a result of such Transaction Litigation, such Sponsor Entity will pay all of such consideration to Parent by wire transfer of immediately available funds promptly (and, in any event, within five Business Days) following the later to occur of (A) the Closing Date and (B) the date on which such Sponsor Entity receives such consideration.

        (d)    Communications.    Each Sponsor Entity shall not, and shall cause its Representatives not to, make any press release, public announcement or other public communication with respect to the business or affairs of MLP, MLP GP, Parent or Merger Sub, including this Agreement and the Merger Agreement and the transactions contemplated hereby and thereby, without the prior written consent of Parent (such consent not to be unreasonably withheld or delayed); provided that such consent shall not be required for (i) any disclosure required by applicable Law (including the filing of this Agreement) and (ii) disclosure of the existence of this Agreement and the Merger Agreement or any other facts

B-4-4


already publicly disclosed regarding the transactions contemplated hereunder and thereunder. Each Sponsor Entity hereby (i) consents to and authorizes the publication and disclosure by Parent of such Sponsor Entity's identity and holding of Covered Units, and the nature of such Sponsor Entity's commitments, arrangements and understandings under this Agreement, and any other information that Parent reasonably determines to be required by applicable Law in any press release or any other disclosure document in connection with the Merger, the GP Equity Transfer or any other transactions contemplated by the Merger Agreement and (ii) agrees as promptly as practicable to notify Parent of any required corrections with respect to any written information supplied by such Sponsor Entity specifically for use in any such disclosure document.

        (e)    Additional Owned Units.    Each Sponsor Entity hereby agrees to notify Parent promptly in writing of the number and description of any Additional Owned Units.

        (f)    Related Party Transactions.    Prior to the Closing, each Sponsor Entity shall, and shall cause its Affiliates to, take such actions as are necessary or required to terminate, effective at or prior to the Closing, each Contract with any of the MLP Group Entities set forth on Schedule II hereto, and the MLP Group Entities shall have no further liabilities or obligations thereunder from and after the Closing.

        (g)    Sponsor Termination Fee.    

B-4-5


B-4-6

Except as permitted or required by this Agreement or the Merger Agreement, the Covered Units are now, and at all times during the Term will be, held by Sponsor Aggregator, free and clear of any and all Liens whatsoever on title, or restrictions on transfer or exercise of any rights of a Unitholder (other than under applicable securities Laws and as created by this Agreement and the MLP Partnership Agreement).

        (d)    Due Execution and Delivery.    This Agreement has been duly executed and delivered by each Sponsor Entity and, assuming due authorization, execution and delivery of this Agreement by Parent and Merger Sub, constitutes a legal, valid and binding obligation of each Sponsor Entity, enforceable against each Sponsor Entity in accordance with its terms.

        (e)    No Filings; No Conflict or Default.    Neither the execution and delivery of this Agreement by each Sponsor Entity nor the consummation by each Sponsor Entity of the transactions contemplated by this Agreement, nor compliance by each Sponsor Entity with any of the terms or provisions of this Agreement, will (i) conflict with or violate any provision of the organizational documents of any Sponsor Entity, (ii) assuming that the Consents referred to in Section 3.5 of the Merger Agreement are obtained and the filings referred to in Section 3.5 of the Merger Agreement are made, (A) violate, in any material respect, any Law or Order applicable to any Sponsor Entity or by which it or any of its respective properties or assets may be bound or affected or (B) violate or conflict with, or result in the loss of any benefit under, constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, result in the termination of or a right of termination or cancellation under, accelerate the performance required by, or result in the creation of any Lien upon any of the respective properties or assets of, any Sponsor Entity under any Contract to which any Sponsor Entity is a party or by which it or any of its respective properties or assets may be bound or affected, (iii) result in the exercisability of any right to purchase or acquire any material asset of any Sponsor Entity, including the Covered Units, or (iv) render the provisions of any Takeover Laws applicable to the Merger or any transactions contemplated by this Agreement, except, in the case of clause (ii) above, for any such violation, conflict, loss, default, termination, modification, cancellation, acceleration, or creation that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on the ability of any Sponsor Entity to consummate the transactions contemplated by this Agreement or the Merger Agreement or perform its obligations under this Agreement.

6.    Termination.    

        (a)    Term.     The term (the "Term") of this Agreement shall commence on the date hereof and shall terminate upon the earliest of (i) the mutual agreement of the Parties, (ii) the consummation of the Closing and (iii) the termination of the Merger Agreement in accordance with its terms; provided that nothing herein shall relieve any Party from liability for any breach of this Agreement prior to its termination.

        (b)    Continuation of Transfer Restriction.     Section 2(a) shall survive any termination of this Agreement until the earlier of (i) such time as it is no longer possible for the Sponsor Termination Fee to become payable under the terms of Section 3(g) or (ii) the Fee Payment Due Date. Notwithstanding anything to the contrary herein (including in Section 2(a)), during the period following the Term during which Section 2(a) continues to survive, a Sponsor Entity may, without the consent of Parent, (A) grant a consent or execute any written consent in or with respect to any or all of the Covered Units, or otherwise enter into a Contract to Transfer Covered Units, in support of an Alternative Proposal,

B-4-9


(B) Transfer its Covered Units to one or more of its Affiliates, provided that any such transferee agrees in writing, in a form reasonably acceptable to Parent, to be bound by the provisions hereof as a "Sponsor Entity" hereunder and provided, further, that no such Transfer will relieve the transferor of any of its obligations with respect to the Sponsor Termination Fee, or (C) if the only circumstances in which the Sponsor Termination Fee may become payable pursuant to Section 3(g)(i) are those contemplated by Section 8.2(b)(iii) of the Merger Agreement, Transfer its Covered Units to any other Person by means of Public Sales, so long as such Public Sales are not intended to effect a transaction that would otherwise constitute the consummation of an Alternative Proposal.

        (c)    Survival of Certain Provisions.     Section 3(c), Section 3(g), this Section 6 and Section 7 shall survive any termination of this Agreement.

7.    Miscellaneous.    

        (a)    Entire Agreement.     This Agreement (together with Schedules I and II and Exhibit A hereto) constitutes the entire agreement, and supersedes all other prior Contracts, both written and oral, among the Parties with respect to the subject matter of this Agreement.

        (b)    Reasonable Efforts.     Subject to the terms and conditions of this Agreement, each Party agrees to use all reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary or desirable under applicable Laws to consummate and make effective the arrangements contemplated hereby. Upon Parent's request and without further consideration, each Sponsor Entity shall execute and deliver such additional documents and take all such further lawful action as may be necessary or desirable to consummate and make effective, in the most expeditious manner practicable, the arrangements contemplated hereby. Without limiting the foregoing, the Sponsor Entities shall execute and deliver to Parent and any of its designees any additional consents or proxies, including with respect to Additional Owned Units, reasonably requested by Parent in furtherance of this Agreement.

        (c)    No Assignment.     This Agreement shall not be assignable by operation of law or otherwise; provided, however, that each of Parent or Merger Sub may, without the consent of any of the Sponsor Entities, assign this Agreement and any of their respective rights and obligations hereunder to one or more Affiliates of Parent or Merger Sub to which rights and obligations under the Merger Agreement are assigned in accordance with the Merger Agreement. Any purported assignment in violation of this Agreement is void.

        (d)    Binding Successors.     Without limiting any other rights Parent may have hereunder in respect of any Transfer of the Covered Units, each Sponsor Entity agrees that this Agreement and the obligations hereunder shall attach to the Covered Units beneficially owned by such Sponsor Entity and shall be binding upon any Person to which legal or beneficial ownership of such Covered Units shall pass, whether by operation of law or otherwise; provided that this Section 7(d) shall not apply to any Person to which legal or beneficial ownership of any Covered Unit passes as contemplated by clause (C) of the last sentence of Section 6(b).

        (e)    Modification or Amendments.     Subject to the provisions of applicable Law, the Parties may modify or amend this Agreement only by written agreement executed and delivered by duly authorized officers of the respective Parties.

        (f)    Tax Consequences.     The Parties acknowledge that the Disaggregation Transfers will constitute a "transfer" pursuant to Section 708(b) of the Code, and shall treat the transfers consistently as such for all income Tax purposes.

        (g)    FIRPTA Certificate.     At the Closing, each Sponsor Entity will deliver to Parent a certificate, dated as of the Closing Date and substantially in the form and to the effect of Exhibit C to the Merger

B-4-10


Agreement, which satisfies the requirements set forth in Treasury Regulation Section 1.1445-2(b)(2), attesting that such Person is not a "foreign person" for U.S. federal income Tax purposes.

        (h)    Notices.     All notices, requests, permissions, waivers and other communications hereunder will be in writing and will be deemed to have been duly given (a) when sent, if sent by facsimile or electronic mail (.pdf), (b) when delivered, if delivered personally to the intended recipient and (c) one Business Day following sending by overnight delivery via an international courier service and, in each case, addressed to a Party at the following address for such Party (or to such other address as will be furnished in writing by any such Party to the other Parties in accordance with the provisions of this Section 7(h)):

        (i)    Severability.     The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision will be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances will not be affected by such invalidity or unenforceability, nor will such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

        (j)    Remedies.     The Parties agree that irreparable damage would occur and that the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were

B-4-11


not performed in accordance with their specific terms or were otherwise breached, and it is accordingly agreed that the Parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 7(j) in the Delaware Court of Chancery or any federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief as provided herein on the basis that (a) either Party has an adequate remedy at law or (b) an award of specific performance is not an appropriate remedy for any reason at law or equity. Each Party further agrees that no Party will be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 7(j), and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument. If Parent commences a Proceeding to enforce its rights under this Agreement to collect the Sponsor Termination Fee or other amounts payable pursuant to Section 3(g), and such Proceeding results in an Order against any Sponsor Entity, the Sponsor Entities shall pay to Parent the costs and expenses (including reasonable and documented attorney's fees and expenses) incurred by Parent and its Affiliates in connection with such Proceeding. The Sponsor Entities shall be jointly and severally liable for any such payment.

        (k)    No Waiver.     The failure of or delay by any Party in exercising any right hereunder will not operate as a waiver thereof nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right hereunder. Any agreement on the part of a Party to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of such Party.

        (l)    No Third Party Beneficiaries.     This Agreement is not intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties.

Board of Directors
PetroLogistics LP
600 Travis, Suite 3250
Houston, TX 77002

Members of the Board:

        We understand that Petrologistics LP ("MLP"), Petrologistics GP LLC, the general partner of MLP ("MLP GP"), Propylene Holdings, LLC ("GP Holdings"), Flint Hills Resources, LLC (the "Buyer"), and FHR Proplylene, LLC, a subsidiary of the Buyer ("Merger Sub"), propose to enter into an Agreement and Plan of Merger and Membership Interest Transfer Agreement, substantially in the form of the draft dated May 27, 2014 (the "Merger Agreement"), which provides, among other things, for (i) the merger (the "Merger") of Merger Sub with and into MLP and (ii) the transfer by GP Holdings to the Buyer of all of the outstanding membership interests in MLP GP (together with the Merger, the "Transaction"). Pursuant to the Merger, MLP will become a subsidiary of the Buyer, and each outstanding Common Unit that is owned by the Unitholders (other than the Sponsors and the Founding Unitholders) ("Public Unitholders") will be converted into the right to receive $14.00 per share in cash (the "Public Merger Consideration"). The terms and conditions of the Transaction are more fully set forth in the Merger Agreement. Capitalized terms used herein but not otherwise defined shall have the meanings ascribed to such terms in the Merger Agreement.

        You have asked for our opinion as to whether the Public Merger Consideration to be received by the Public Unitholders pursuant to the Merger Agreement is fair on the date hereof from a financial point of view to the Public Unitholders.

        For purposes of the opinion set forth herein, we have:

C-1


Table of Contents

        We have assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to us by MLP, and formed a substantial basis for this opinion. With respect to the financial projections, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of MLP of the future financial performance of MLP. In addition, we have assumed that the Transaction will be consummated in accordance with the terms set forth in the Merger Agreement without any material waiver, amendment or delay of any terms or conditions. Morgan Stanley has assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed Transaction, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the proposed Transaction. We are not legal, tax or regulatory advisors. We are financial advisors only and have relied upon, without independent verification, the assessment of MLP and its legal, tax or regulatory advisors with respect to legal, tax or regulatory matters. We express no opinion with respect to the fairness of the amount or nature of the compensation to any of MLP's officers, directors or employees, or any class of such persons, relative to the Public Merger Consideration to be received by the Public Unitholders in the Transaction. Morgan Stanley also expresses no opinion as to the fairness of the Public Merger Consideration to any party other than the Public Unitholders or the fairness of the Public Merger Consideration relative to the consideration to be received by any other Unitholders, including the Sponsors and the Founding Unitholders. We have been advised that all of the economic terms relating to the Transaction are as set forth in the Merger Agreement. In that regard, we understand that the Sponsors and the Founding Unitholders are not receiving any other form of consideration or payment in connection with the Transaction, other than the Sponsor Merger Consideration. We do not express any view on, and this opinion does not address, any other term or aspect of the Merger Agreement or the transactions contemplated thereby or any term or aspect of any other agreement or instrument contemplated by the Merger Agreement or entered into or amended in connection therewith, or the process undertaken by MLP to evaluate, negotiate and agree on the Transaction. Our opinion does not address the relative merits of the Transaction as compared to any alternative transaction, or other alternatives, or whether or not such alternatives (if any) could be achieved. We have not made any independent valuation or appraisal of the assets or liabilities of MLP, nor have we been furnished with any such valuations or appraisals. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

        We have been retained by the Board of Directors of the MLP GP (the "Board"), and our role in connection with the Transaction has been limited to providing a financial opinion letter to the Board in connection with the Transaction. Under the terms of our engagement letter with you, our role prior to the execution of the Merger Agreement has not included advising on or negotiating the terms of the Merger Agreement. In addition, Morgan Stanley has given the Board its views on the possibility of unsolicited third party bids in light of the deal protection provisions in the Merger Agreement. Furthermore, as requested by the Board, after the announcement of the Transaction, Morgan Stanley will (i) act as the MLP's financial advisor, and assist the Board, in evaluating any unsolicited proposal with respect to the Transaction and (ii) help the Board determine whether any unsolicited proposal constitutes a Superior Proposal.

        We have been engaged by the Board in connection with the Transaction and will receive a fee for our services, a portion of which is contingent upon rendering of this financial opinion, and the

C-2


Table of Contents

remainder of which is contingent on completion of the Transaction. In the two years prior to the date hereof, we have provided financial advisory and financing services for MLP, the Sponsors, the Buyer and their respective affiliates and portfolio companies and have received fees in connection with such services. Morgan Stanley may also seek to provide such services to the Buyer, MLP, the Sponsors and their respective affiliates and portfolio companies in the future and expects to receive fees for the rendering of these services.

        Please note that Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Our securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect transactions, for their own account or the accounts of its customers, in debt or equity securities or loans of the Buyer, MLP, or any other company, or any currency or commodity, that may be involved in the Transaction, or any related derivative instrument.

        This opinion has been approved by a committee of Morgan Stanley investment banking and other professionals in accordance with our customary practice. This opinion is for the information of the Board and may not be disclosed or used for any other purpose without our prior written consent, except that a copy of this opinion may be included in its entirety in any filing MLP is required to make with the Securities and Exchange Commission in connection with the Transaction if such inclusion is required by applicable law. Morgan Stanley expresses no opinion or recommendation as to how the Public Unitholders or any other holders of Common Units should vote in connection with any action by written consent of Unitholders or at any meeting of Unitholders in connection with the Transaction.

        Based on and subject to the foregoing, we are of the opinion on the date hereof that the Public Merger Consideration to be received by the Public Unitholders pursuant to the Merger Agreement is fair from a financial point of view to the Public Unitholders.

    Very truly yours,

 

 

MORGAN STANLEY & CO. LLC

PetroLogistics LP
600 Travis Street, Suite 3250
Houston, Texas 77002

Members of the Board of Directors of PetroLogistics GP LLC:

        We understand that PetroLogistics LP, a Delaware limited partnership (the "Partnership"), proposes to enter into an Agreement and Plan of Merger and Membership Interest Transfer Agreement (the "Merger Agreement"), by and among the Partnership, PetroLogistics GP LLC, a Delaware limited liability company and the general partner of the Partnership (the "General Partner"), Propylene Holdings LLC, a Delaware limited liability company ("GP Holdings"), Flint Hills Resources, LLC, a Delaware limited liability company and a wholly-owned subsidiary of Koch Industries, Inc. ("Koch") (the "Parent") and FHR Propylene, LLC, a Delaware limited liability company and subsidiary of the Parent ("Merger Sub") (the "Merger"). In the Merger, (i) each outstanding Common Unit (as defined in the Merger Agreement) (the "Partnership Common Units") of the Partnership, excluding those units held by the Sponsors (as defined in the Merger Agreement) and the Founding Unitholders (as defined in the Merger Agreement), shall be converted into the right to receive $14.00 in cash (the "Public Merger Consideration") and (ii) each Partnership Common Unit held by the Sponsors and the Founding Unitholders shall be converted into the right to receive $12.00 in cash. The terms and conditions of the Merger are more fully set forth in the Merger Agreement and terms used herein and not defined shall have the meanings ascribed thereto in the Merger Agreement.

        The Board of Directors of the General Partner (the "Board") has asked us whether, in our opinion, the Public Merger Consideration is fair, from a financial point of view, to the holders of Partnership Common Units (other than the Sponsors and the Founding Unitholders).

        In connection with rendering our opinion, we have, among other things:

        For purposes of our analysis and opinion, we have assumed and relied upon, without undertaking any independent verification of, the accuracy and completeness of all of the information publicly available and all of the information supplied or otherwise made available to, discussed with, or reviewed by us, and we assume no liability therefor. With respect to the projected financial and operating data relating to the Partnership, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of the Partnership as to the future financial performance of the Partnership under the assumptions stated therein. We express no view as to the projected financial and operating data relating to the Partnership or any judgments, estimates or assumptions on which they are based. We have relied, at your direction, without independent verification, upon the assessments of the management of the Partnership as to the future financial and operating performance of the Partnership.

        For purposes of rendering our opinion, we have assumed, in all respects material to our analysis, that the representations and warranties of each party contained in the Merger Agreement (in the draft form reviewed by us) are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement and that all conditions to the consummation of the Merger will be satisfied without material waiver or modification thereof. We have further assumed that all governmental, regulatory or other consents, approvals or releases necessary for the consummation of the Merger will be obtained without any material delay, limitation, restriction or condition that would have an adverse effect on the Partnership or the consummation of the Merger or materially reduce the benefits of the Merger to the holders of Partnership Common Units. We have assumed the final versions of all documents reviewed by us in draft form conform in all material respects to the drafts reviewed by us.

        We have not made, nor assumed any responsibility for making, any independent valuation or appraisal of the assets or liabilities of the Partnership, nor have we been furnished with any such appraisals, nor have we evaluated the solvency or fair value of the Partnership under any state or federal laws relating to bankruptcy, insolvency or similar matters. Our opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, monetary, market, regulatory and other conditions and circumstances as they exist and as can be evaluated on the date hereof. It is understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise or reaffirm this opinion.

        We have not been asked to pass upon, and express no opinion with respect to, any matter other than the fairness of the Public Merger Consideration, from a financial point of view, as of the date hereof, to the holders of Partnership Common Units (other than the Sponsors and the Founding Unitholders). We do not express any view on, and our opinion does not address, the fairness of the Merger to, or any consideration received in connection therewith by, the Sponsors and the Founding Unitholders or the holders of any other securities, or any creditors or other constituencies, of the Partnership, nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Partnership or any of the other parties to the Merger Agreement, or any class of such persons, whether relative to the Public Merger Consideration or otherwise. We have assumed that any modification to the structure of the Merger will not vary in any respect material to our analysis. Our opinion does not address the relative merits of the Merger as compared to other business or financial strategies that might be available to the Partnership, nor does it address the underlying business decision of the Partnership to engage in the Merger. In arriving at our opinion, we were not authorized to solicit, and did not solicit, interest from any third party with respect to the acquisition of any or all of the Partnership Units or any business combination or other extraordinary transaction involving the Partnership. This letter, and our opinion, does not constitute a recommendation to the Board or to any other persons in respect of the Merger, including as to how

D-2


Table of Contents

any holder of Partnership Common Units should vote or act in respect of the Merger. We express no opinion herein as to the price at which Partnership Common Units will trade at any time. We are not legal, regulatory, accounting or tax experts and have assumed the accuracy and completeness of assessments by the management of the Partnership and their advisors with respect to legal, regulatory, accounting and tax matters.

        We will receive a fee for our services upon the rendering of this opinion. The Partnership has also agreed to reimburse our expenses and to indemnify us against certain liabilities arising out of our engagement. During the two year period prior to the date hereof, no material relationship existed between Evercore Group L.L.C. and its affiliates and the Partnership, the Sponsors, Koch or any of their respective affiliates pursuant to which compensation was received by Evercore Group L.L.C. or its affiliates as a result of such a relationship. We may provide financial or other services to the Sponsors and Koch or their respective affiliates in the future and in connection with any such services we may receive compensation.

        Evercore and its affiliates engage in a wide range of activities for their own accounts and the accounts of customers. In connection with these businesses or otherwise, Evercore and its affiliates and/ or their respective employees, as well as investment funds in which any of them may have a financial interest, may at any time, directly or indirectly, hold long or short positions and may trade or otherwise effect transactions for their own accounts or the accounts of customers, in debt or equity securities, senior loans and/ or derivative products relating to the Partnership, the Sponsors, Koch and their respective affiliates, for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities or instruments.

        This letter, and the opinion expressed herein, is addressed to, and is solely for the information and benefit of, the Board in connection with its evaluation of the proposed Merger.

        The issuance of this opinion has been approved by an Opinion Committee of Evercore Group L.L.C.

        This letter, and the opinion expressed herein, may not be disclosed, quoted, referred to or communicated (in whole or in part) to, or relied upon by, any third party, nor shall any public reference to us be made, for any purpose whatsoever except with our prior written consent in each instance, except that the Partnership may reproduce a copy of this opinion in full in any document related to the Merger that is required to be filed with the U.S. Securities and Exchange Commission and required to be mailed by the Partnership to its unitholders, provided, however, that all references to Evercore or this opinion in any such document and any description or inclusion of this opinion and advice or related analysis therein shall be subject to our prior written consent with respect to form and substance, which consent shall not be unreasonably withheld or delayed.

        Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Public Merger Consideration is fair, from a financial point of view, to the holders of Partnership Common Units (other than the Sponsors and the Founding Unitholders).

    Very truly yours,

Organizational Structure

        The following chart provides a simplified overview of our organizational structure.

GRAPHIC

E-1


Our Business

        We currently own and operate the only U.S. propane dehydrogenation (or "PDH") facility (or "our facility") producing propylene from propane. Propylene is one of the basic building blocks for petrochemicals and is utilized in the production of a variety of end uses including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. We are the only independent, dedicated "on-purpose" propylene producer in North America. We are strategically located in the vicinity of the Houston Ship Channel which is situated within the largest propylene consumption region in North America. We also have access to the leading global fractionation and storage hub for propane located at Mt. Belvieu, Texas. Our location provides us with excellent access and connectivity to both customers and feedstock suppliers.

        We currently have multi-year contracts for the sale of our propylene with The Dow Chemical Company ("Dow"), Total Petrochemicals & Refining USA, Inc. ("Total"), BASF Corporation ("BASF") and INEOS Olefins and Polymers USA ("INEOS") that expire between 2016 and 2018 and a one-year contract with LyondellBasell Industries N.V. ("LyondellBasell") that ends in December 2014. Our customer contracts provide for minimum and maximum offtake volumes, with the minimum customer-contracted volumes representing approximately 75% of our current facility capacity and the maximum reflecting approximately 96% of our current facility capacity. Each of our customer contracts contain pricing terms based upon market rates. In addition to our contracted sales, we have made and will continue to make additional propylene sales on a spot basis. Also, if necessary, we may purchase propylene in order to meet short-term customer obligations.

        Propylene comprised 98% and 97% of our sales in 2013 and 2012, respectively. In addition to propylene, we also produce commercial quantities of hydrogen and C4 mix/C5+ streams.

        We derive our sales from three different sources: propylene, hydrogen, and C4 mix/C5+ streams. In general, we deliver our propylene to our customers by pipeline on a continuous basis and ratably throughout the month. We may elect to store product to help ensure that a constant supply of propylene is available to our customers in the event of a temporary outage. For more information relating to the sales, assets, profits and losses of our business, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" as well as "Item 8. Financial Statements and Supplementary Data."

Contracted Propylene Sales

        Since commencing operations, we have been party to long-term propylene sales contracts with Dow, Total and INEOS. After optimizing our facility, with a resulting increase in stated capacity, we added LyondellBasell and BASF as contract customers. Each contract details both minimum and maximum offtake volumes as well as pricing terms. As is customary in the propylene industry, our customer contracts are based on market prices. Consistent with industry practice for such contracts, our pricing terms with these customers reflect a specified discount to the monthly benchmark propylene price published by IHS Inc. (or "IHS"), formerly Chemical Market Associates, Inc. For the year ended December 31, 2013, Dow, Total, INEOS, BASF and LyondellBasell accounted for 44%, 21%, 18%, 9% and 6% of our total sales, respectively.

        We deliver propylene to these customers through our integrated pipeline system, which directly connects our facility to the Dow and Total plants and through interconnected third-party pipelines, which connect our facility to INEOS, BASF, LyondellBasell and to other potential propylene customers.

Spot-Market Propylene Sales

        Through our integrated pipeline system, we are also able to access other consumers of propylene which we are able to supply on a spot basis with any excess production. We are connected to major propylene consumers with the necessary logistics already in place. In 2013, we limited our spot sales activity in order to build inventory in anticipation of our first triennial maintenance project, or turnaround, which commenced on September 28, 2013, and was completed on October 30, 2013.

Hydrogen Gas Sales

        As part of the PDH process, we produce commercially saleable quantities of hydrogen. Hydrogen is primarily consumed in numerous refinery processes, including fuel desulphurization. We are party to a ten-year contract for the sale of our hydrogen production. Any volumes we do not sell are consumed in our fuel system, reducing our requirement to purchase natural gas.

        An additional benefit of our hydrogen production is that it provides a natural hedge against natural gas prices because hydrogen prices are indexed to natural gas. While an increase in natural gas prices would increase our operating costs (since we consume natural gas as a fuel), such increase would be partially offset by the higher prices we would earn through our hydrogen sales.

C4 Mix/C5+ Streams Sales

        We also produce commercial quantities of C4 mix/C5+ streams. We sell the C4 mix stream to specialty chemical consumers or refiners. These customers transport the purchased volumes from our facility by truck with title transferring at our facility. The C5+ stream, which is heavy in aromatics, is transported by our pipeline to a Kinder Morgan terminal, and then sold to a third party.

Our Business Strategy

        Our objective is to maximize our quarterly cash distributions to our unitholders by executing the following strategies:

E-3


Our History

        We are a Delaware limited partnership that was formed in June 2011.

        We purchased a former olefins manufacturing facility from ExxonMobil Corporation (or "ExxonMobil") in March 2008, and that facility was used as the platform for the construction of our propane dehydrogenation propylene production facility. Initial production at our facility commenced in October 2010. After an approximately year-long start-up and plant optimization phase, our facility demonstrated production rates at our current stated capacity (approximately 20% above our original nameplate capacity) beginning in December 2011.

        On May 9, 2012, we completed our IPO. Our common units are traded on the New York Stock Exchange (or "NYSE") under the symbol "PDH". Pursuant to a Registration Statement on Form S-1, as amended through the date of its effectiveness, we sold 1,500,000 common units, and Propylene Holdings LLC (or "Propylene Holdings") sold 33,500,000 common units. We received net proceeds of approximately $24.0 million from our sale of the common units, after deducting underwriting discounts.

Our Sponsors

        Lindsay Goldberg is a private equity investment firm with approximately $8.3 billion of capital under management that focuses on partnering with entrepreneurial management teams and closely held and family-owned businesses. The firm typically invests in companies in North America and Western Europe in the manufacturing, energy, financial and business services industries. Lindsay Goldberg has an investment structure that permits ownership for up to 20 years and has had a close relationship with our management since 2000.

        York Capital is an event-driven global investment firm with approximately $19 billion of capital under management. The firm focuses on a variety of strategies, including private equity investing. Established in 1991, York Capital has offices in New York, Washington DC, London and Hong Kong.

E-4


        Lindsay Goldberg and York Capital have been instrumental in our management team's effort to implement the optimal operating and financial platform for the Partnership. Lindsay Goldberg and York Capital indirectly own 67% and 17% interests in our General Partner and 69,690,798 and 17,422,701 common units, respectively.

Our Facility

        Our state-of-the-art facility is strategically located in the vicinity of the Houston Ship Channel on a site that was formerly the site of an ExxonMobil ethylene cracker. We believe the former ExxonMobil site is ideally suited for our facility based on its location, infrastructure, utilities, permits, logistics and certain operating units that we were able to utilize in the PDH process. As part of our purchase of the site, we acquired all major environmental and regulatory permits, and we were able to take advantage of these permits through amendments to reflect the specifications of the PDH process. Our facility had an original annual production capacity of 1.2 billion pounds of propylene. However, based on plant optimization and operating improvements our facility currently has an annual production capacity of approximately 1.4 billion pounds. In 2013, we produced 1.1 billion pounds of propylene. Production at our facility was reduced in 2013 as we completed our first triennial plant turnaround in October 2013. During the turnaround, we shut down the facility for 32 days to replace the reactor catalyst and perform other major maintenance activities designed to help ensure the long-term reliability and safety of integrated plant machinery.

        Our facility is situated within the largest propylene consumption region in North America. We also have access through third parties to the leading global fractionation and storage hub for propane, our feedstock, located at Mt. Belvieu, Texas, which is approximately 30 miles from our facility.

        Our customer contracts provide for potential maximum annual offtake volumes of approximately 1.4 billion pounds of propylene, approximately 96% of our facility's maximum annual production capacity. We believe that our facility has adequate capabilities to provide our customers with their contracted volumes of propylene. In the event that production at our facility is curtailed for any reason (including because of mechanical failure) and we elect not to declare force majeure, we believe that we will be able to satisfy our obligations under our customer contracts through our inventory and spot-market purchases of propylene.

E-5


        The following is an illustration of the extensive pipeline system either connected to or located within the vicinity of our facility which makes our location well-suited for the business of propylene production, followed by a table indicating pipeline system ownership:

        Propane dehydrogenation is a straightforward chemical process that produces propylene by removing two atoms of hydrogen (H2) from one molecule of propane (C3 H8) to produce one molecule of propylene (C3 H6). The technology that is used is the CATOFIN process, which is licensed to us by CB&I Lummus on a non-exclusive and perpetual basis. We selected this technology because of its straightforward design, its record of high reliability and expected low operating costs. Further, our team developed and implemented a variety of energy cost-saving processes which improved upon the typical CATOFIN design, certain of which processes are the subject of a currently pending patent application. Our license with CB&I Lummus requires us to make additional payments if our annual production exceeds the amount set forth in our license. In 2012 we made a one-time payment to CB&I Lummus to cover actual increases in our production in excess of the original design basis and to allow for certain additional production increases. To the extent we further increase our operational capacity at the facility beyond the new designated level, we are responsible for additional one-time payments to CB&I Lummus for each metric ton of additional capacity above the new designated level.

E-6


        Propane dehydrogenation via the CATOFIN process consists of two general phases: the dehydrogenation phase and the purification phase. In the dehydrogenation phase, the propane feedstock is passed under a vacuum over a chromium—based catalyst contained in fixed bed reactors. Prior to the propane reaching the reactors the catalyst beds are heated to a high temperature with heated compressed air. After the dehydrogenation phase, the resulting propane/propylene mixed effluent is sent to the purification section of our facility where it is separated into polymer grade and chemical grade propylene, C4mix/C5+ streams, hydrogen and also a stream of propane that was not dehydrogenated in each pass over the catalyst beds. The undehydrogenated propane stream is then recycled back to the reactor section. The purification section of our facility utilizes a series of distillation towers, refrigeration units and other apparatus common to many olefins plants. Using our propane dehydrogenation process, approximately 1.2 pounds of propane is required to produce one pound of propylene. This ratio is referred to as the monomer factor.

        The CATOFIN propane dehydrogenation process is illustrated below:


Process Flow Diagram

GRAPHIC

        Although our facility relies on the typical CATOFIN process design, we also implemented a number of process innovations that reduce our energy costs. Certain of these process innovations are subject to a pending patent application. For example, the facility produces regeneration air (the hot air utilized to heat the catalyst beds in the reactors) using gas turbines instead of the typical compressor/heater configuration. Also, the hydrogen by-product is captured and purified by a pressure swing absorption unit and then sold to a third party rather than being merely sent to the fuel system in its unpurified form.

        During the October 2013 turnaround, in addition to unloading and reloading six million pounds of catalyst, we also upgraded major systems such as the waste heat boiler and the regeneration air heater. We upgraded our emergency shut-off systems for three of our large compressors and reconfigured the air diffusers inside each reactor. We also performed significant maintenance including inspecting and rebuilding reactor valves, cleaning heat exchangers, and repairing expansion joints. Some of the preventative maintenance included upgrades to our electrical distribution system, upgrades to our facility's distributed control system and upgrades to our steam system.

E-7


Feedstock Supply

        Propane is our sole feedstock. Propane is produced by extraction and separation from natural gas production streams via gas processing facilities and fractionation. It is also produced as a by-product of refineries. Our propane is currently provided to us by Enterprise Products Operating LLC (together with its affiliates, "Enterprise") under a multi-year contract with market-based pricing consistent with industry practice. Under the propane supply contract, we pay a market price based on the published monthly average price for propane. The initial term of the propane supply contract is for a period of five years (expiring September 30, 2015). Enterprise delivers the propane we purchase to our facility through a connection to Enterprise's propane pipeline system.

        We believe that our supply strategy meets our ongoing feedstock requirements. However, if we choose not to or are unable to renew our Enterprise contract, we believe that, given our location, alternative propane supplies will be available from other suppliers in order to meet our production requirements.

Competition

        We consider companies with net long positions in propylene to be our direct competitors, including Enterprise, Chevron Phillips, ExxonMobil Chemical, Shell Chemical, Flint Hills and the Williams Companies. Most of our competitors have significantly greater financial and other resources than us and are engaged on a national or international basis in many segments of the petroleum products business, including refining, transportation and marketing, on a scale substantially larger than ours.

        Competition in our industry is determined by price considerations, logistics and, to some extent, stability of supply. Our ability to compete effectively depends on our responsiveness to customer needs, our pipeline connectivity to customer facilities and our ability to provide reliable supply at competitive prices. We are the only independent dedicated on-purpose propylene production facility in North America. We believe this is a significant advantage because it enables us to provide customers a more consistent, predictable supply offering than conventional suppliers that produce propylene as a by-product or co-product from other refinery processes, such as ethylene cracking. However, it is possible that in future years competition could come from the construction of additional on-purpose propylene facilities and offer our customers similar capabilities.

        See "Item 1A. Risk Factors—Risks Related to our Business—We face competition from other propylene producers."

Environmental Matters

        The petrochemical business is subject to extensive and frequently changing federal, state and local laws and regulations relating to the protection of human health, workplace safety and the environment. These laws, their underlying regulatory requirements and their enforcement impact our business in a number of respects by imposing:

        Environmental laws and regulations change regularly and any changes that result in more stringent requirements may cause us to make capital expenditures and could affect our operations and financial

E-8


position adversely. While we believe that we are in substantial compliance with currently applicable environmental laws and regulations and that continued compliance with existing requirements would not have a material adverse impact on us or our business, there is no assurance that this trend will continue in the future. Failure to comply with environmental laws and regulations may result in the assessment of administrative, civil and criminal fines and penalties and the imposition of injunctive relief.

        Our operations are subject to the requirements of the federal Occupational Safety and Health Act ("OSHA") and comparable state statutes that regulate the protection of the health and safety of workers. In addition, the OSHA hazard communication standard requires that we maintain information about hazardous materials used or produced in our operations and that we provide this information to employees, state and local government authorities and local residents. Failure to comply with OSHA requirements, including general industry standards, recordkeeping requirements and monitoring of occupational exposure to regulated substances could reduce our ability to make distributions to our unitholders if we are subjected to fines or significant compliance costs.

Federal Clean Air Act

        The federal Clean Air Act ("CAA") and its implementing regulations as well as the corresponding state laws and regulations that regulate emissions of pollutants into the air affect our operations both directly and indirectly. We are required to comply with federal and state air permitting regulations or emissions control requirements relating to specific air pollutants. Some or all of the standards promulgated pursuant to the federal CAA, or any future standards which may be promulgated, may require the installation of controls or changes to our operations. If new controls or changes to operations are needed, then the costs could be material.

        The federal CAA requires us, in certain situations, to obtain various construction and operating permits and to incur capital expenditures to install certain air pollution control devices at our PDH facility. Some of the applicable programs are the various general and specific source standards under the National Emission Standard for Hazardous Air Pollutants, New Source Performance Standards ("NSPS"), and New Source Review. Some of these programs are implemented by the Texas Commission on Environmental Quality ("TCEQ") with oversight by the Environmental Protection Agency ("EPA"). We may incur substantial capital expenditures to maintain compliance with these and other air emission regulations. In addition, the EPA has objected to the issuance of air permits on various grounds, creating uncertainty about the authority of TCEQ to issue permits for air emissions, which could have a material adverse effect on our operations in the event that the EPA were to object to a permit issued by TCEQ for our operations.

        In addition, the EPA adopted rules to require the development of a Risk Management Plan to prevent the accidental release of hazardous substances that could harm public health or the environment.

        The TCEQ has finalized rules in connection with CAA Section 185 fee regulations. The fees are expected to be imposed on businesses starting in 2014. We believe, however, that such fees and our other state and federal air emission obligations under the CAA and similar statutes will not have a material adverse effect on our operations, and the requirements are not expected to be any more burdensome to us than any other similarly situated company.

Climate Change

        Responding to certain scientific studies suggesting that emissions of certain gases, commonly referred to as greenhouse gases ("GHG"), which include gases associated with oil and gas production such as carbon dioxide, methane, and nitrous oxide, among others, may be contributing to a warming of the earth's atmosphere and other adverse environmental effects, the U.S. Congress has proposed

E-9


numerous legislative measures to restrict or require emissions fees for greenhouse gases. However, to date, there have been no resulting federal regulations promulgated that specifically restrict greenhouse gas emissions, which has resulted in certain states and regional partnerships taking the initiative. Efforts to curb greenhouse gas emissions continue to be led by the EPA greenhouse gas regulations and the efforts of certain states.

        Following the U.S. Supreme Court's 2007 decision in Massachusetts, et al. v. EPA, finding that greenhouse gases fall within the CAA definition of "air pollutant," the EPA determined that greenhouse gases from certain sources "endanger" public health or welfare. As a result, the EPA has taken the position that the CAA requires an assessment of greenhouse gas emissions within the meaning of certain provisions of the CAA permitting process for certain large new or modified stationary sources under the EPA's Prevention of Significant Deterioration ("PSD") and Title V permit programs beginning in 2011. Facilities triggering permit requirements may be required to reduce greenhouse gas emissions consistent with "best available control technology" standards which have yet to be developed. Such changes will also affect state air permitting programs in states that administer the CAA under a delegation of authority. Additionally, in November 2010, the EPA finalized rules expanding its Mandatory Greenhouse Gas Reporting Rule to apply to the oil and natural gas industries.

        President Obama recently announced his Climate Action Plan. One of the major components of this plan is to reduce greenhouse gas emissions from the electricity generation sector. On September 20, 2013, the EPA proposed separate standards for coal and natural gas-fired power plants. We expect any final rule that may be promulgated as a result of this proposed rule to be appealed and otherwise subjected to various judicial challenges, the outcome of which cannot be predicted. Although these rules do not apply directly to our operations, should the EPA impose comparable regulations on us, the cost of compliance could be significant.

        To the extent that our operations are subject to the EPA's GHG regulations, we may face increased capital and operating costs associated with new or expanded facilities. Significant expansions of our existing facility or construction of new facilities may be subject to the CAA'S PSD requirements under the EPA's GHG "Tailoring Rule." Any further regulation may increase our operational costs.

        In June 2013, the Texas Legislature passed a law authorizing the TCEQ to develop rules to authorize major sources of GHG emissions to the extent required by federal law. Texas is currently subject to a Federal Implementation Plan (FIP), which means that major sources of GHG emissions are required to obtain a GHG permit from the EPA. In February 2014, the EPA issued a pre-publication copy of a proposed rule that, if adopted, approves Texas' revised State Implementation Plan (SIP) and would transfer GHG permitting in Texas from the EPA to the TCEQ. In anticipation of the final approval of the EPA's rule, the TCEQ has proposed rules regarding a takeover of the GHG permitting program. The TCEQ regulations are expected to be published and take effect later this year.

Clean Water Act ("CWA")

        The federal CWA affects our operations by prohibiting discharges of pollutants into, or impacting, navigable waters except in compliance with permits issued by federal and state governmental agencies. Regular monitoring, reporting requirements and performance standards are preconditions for the issuance and renewal of permits. The federal government has delegated authority to Texas to manage the CWA permit and enforcement process. The CWA and comparable state statutes provide for civil, criminal, and administrative penalties for the unauthorized discharge of pollutants into wetlands or other waters and impose liability on parties responsible for those discharges for the cost of cleaning up any environmental damage or natural resource damages resulting from the release. Our business maintains waste water and storm water discharge permits as required under the National Pollutant Discharge Elimination System program and the Texas Pollutant Discharge Elimination System program. Under the CWA, onshore facilities that could reasonably be expected to cause substantial harm to the

E-10


environment by discharging pollutants to navigable waters are required to maintain plans for spill prevention, preparedness and response. We have implemented internal programs to oversee our compliance efforts and we believe that we are in substantial compliance with the CWA. In the future, changes to the CWA, state law, or state and federal regulations could require us to make additional capital expenditures or incur additional costs in order to comply with new rules and could have a significant effect on our profitability.

Emergency Planning and Community Right-to-Know Act ("EPCRA")

        The EPCRA requires facilities to report certain chemical inventories to local emergency planning committees and response departments. We believe that we are in substantial compliance with our EPCRA reporting requirements.

Resource Conservation and Recovery Act ("RCRA")

        Our operations are subject to the RCRA requirements for the generation, management, and disposal of hazardous wastes. These requirements entail certain costs. When feasible, materials that would be subject to RCRA are recycled instead of being disposed of. Though we believe that we are in substantial compliance with the existing requirements of RCRA, we cannot assure you that compliance with existing and future RCRA requirements will not entail costs that are significant.

Comprehensive Environmental Response, Compensation, and Liability Act (or "CERCLA")

        CERCLA and comparable state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons who are considered to be responsible for or contributed to the release of a "hazardous substance" into the environment. These persons include the owner or operator of the facility where the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the facility. Under CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain health studies. CERCLA also authorizes the EPA, and in some instances third parties, to act in response to threats to the public health or the environment and to seek to recover from the responsible persons the costs they incur. It is possible for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. In the course of our ordinary operations, we may generate substances that fall within CERCLA's definition of a hazardous substance, and as a result, we may be jointly and severally liable under CERCLA for all or part of the costs required to clean up sites at which those hazardous substances have been released into the environment.

        Under CERCLA, we could be required to remove or remediate previously disposed wastes, including wastes disposed of or released by prior owners or operators, to clean up contaminated property, including groundwater contaminated by prior owners or operators.

Safety, Health and Security Matters

        Our extensive safety program includes, among other things, (1) employing two full-time safety professionals, (2) implementing policies and procedures to protect employees and visitors at our facility (3) conducting routine safety tests at our facility and (4) ensuring that each employee undergoes the required safety, hazard and task training.

E-11


Employees

        To carry out our operations, our General Partner currently employs approximately 110 employees. Our employees are not represented by a labor union and are not covered by a collective bargaining agreement. We believe that we have good relations with our General Partner's employees.

Website Access to Our Periodic SEC Reports

        We file and furnish Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and amendments to these reports with the SEC, which are available free of charge through our website (http://www.petrologistics.com) as soon as reasonably practicable after such reports are filed with or furnished to the SEC.

Item 1A.    Risk Factors

        We are subject to certain risks and hazards due to the nature of the business activities we conduct, including the risks discussed below and set forth elsewhere in this annual report. If any of the following risks and uncertainties develops into an actual event, our business, financial condition, cash flows and results of operations could be materially adversely affected. In that case, we might not be able to pay distributions on our common units and the trading price of our common units could decline materially.

Risks Related to Our Business

We may not have sufficient available cash to pay any quarterly distributions on our common units.

        We may not have sufficient available cash each quarter to enable us to pay any distributions to our common unitholders. The amount of cash we will be able to distribute on our common units principally depends on the amount of cash we generate from our operations, which is primarily dependent upon the operating margins we generate. Our operating margins, and thus, the cash we generate from operations have been volatile, and we expect that they will continue to fluctuate from quarter to quarter based on, among other things:

        In addition, the actual amount of cash we will have available for distribution will depend on other factors, some of which are beyond our control, including:

E-12


        Our partnership agreement does not require us to pay a minimum quarterly distribution. The amount of distributions that we pay, if any, and the decision to pay any distribution at all, will be determined by the board of directors of our General Partner. Our quarterly distributions, if any, will be subject to significant fluctuations based on the above factors.

        For a description of additional restrictions and factors that may affect our ability to pay distributions, see "Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities—Our Cash Distribution Policy."

The amount of our quarterly cash distributions, if any, can vary significantly both quarterly and annually and will be directly dependent on the performance of our business. Unlike most publicly traded partnerships, we do not have a minimum quarterly distribution or employ structures intended to consistently maintain or increase distributions over time.

        Investors who are looking for an investment that will pay predictable quarterly distributions should not invest in our common units. We expect our business performance will be more cyclical and volatile, and our cash flows will be less stable, than the business performance and cash flows of most publicly traded partnerships. As a result, our quarterly cash distributions will be cyclical and volatile and are expected to vary quarterly and annually. Unlike most publicly traded partnerships, we do not have a minimum quarterly distribution or employ structures intended to consistently maintain or increase distributions over time. The amount of our quarterly cash distributions will be directly dependent on the performance of our business, which will be volatile as a result of a number of factors including fluctuations in propane and propylene prices and the demand for propylene products. Because our quarterly distributions will be subject to significant fluctuations directly related to the cash we generate after payment of our fixed and variable expenses and other cash reserves established by our General Partner, future quarterly distributions paid to our unitholders will vary significantly from quarter to quarter and may be zero. Given the cyclical and volatile nature of our business, our unitholders will have direct exposure to fluctuations in the price of propylene and the cost of propane.

The amount of cash we have available for distribution to unitholders depends primarily on our cash flow and not solely on profitability.

        The amount of cash we have available for distribution depends primarily upon our cash flow and not solely on profitability, which may be affected by non-cash items. For example, we may have extraordinary capital expenditures and major maintenance expenses in the future. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operation—Liquidity and Capital Resources—Capital Spending." As a result, we may make cash distributions during periods when we report losses and may not make cash distributions during periods when we report net income.

The board of directors of our General Partner may modify or revoke our cash distribution policy at any time at its discretion. Our partnership agreement does not require us to pay any distributions at all.

        The board of directors of our General Partner has adopted a cash distribution policy pursuant to which we will distribute all of the available cash we generate each quarter to unitholders of record on a pro rata basis. However, the board may change such policy at any time at its discretion and could elect not to pay distributions for one or more quarters. See "Our Cash Distribution Policy."

E-13


        Our partnership agreement does not require us to pay any distributions at all. Accordingly, investors are cautioned not to place undue reliance on the permanence of such a policy in making an investment decision. Any modification or revocation of our cash distribution policy could substantially reduce or eliminate the amounts of distributions to our unitholders. The amount of distributions we make, if any, and the decision to make any distribution at all will be determined by the board of directors of our General Partner, whose interests may differ from those of our common unitholders. Our General Partner has limited fiduciary and contractual duties, which may permit it to favor its own interests or the interests of Propylene Holdings and its direct and indirect owners to the detriment of our common unitholders.

The propylene business is, and propylene prices are, cyclical and highly volatile and have experienced substantial downturns in the past. Cycles in demand and pricing could potentially expose us to significant fluctuations in our operating and financial results, and expose you to substantial volatility in our quarterly cash distributions and material reductions in the trading price of our common units.

        We are exposed to fluctuations in propylene demand and supply in the petrochemical industry. These fluctuations historically have had and could in the future have significant effects on prices and, in turn, significant effects on our financial condition, cash flows and results of operations, which could result in significant volatility in or material adverse effects on the price of our common units or our ability to make quarterly cash distributions on our common units.

        Propylene is a commodity, and its price can be cyclical and highly volatile. The price of propylene depends on a number of factors, including the price of crude oil and other commodities, general economic conditions, cyclical trends in end-user markets and supply and demand imbalances.

        Demand for propylene is dependent on demand for petrochemicals by the global construction, automotive and housing industries. Propylene supply is affected by available capacity and operating rates, raw material costs, government policies and global trade. A decrease in propylene prices not accompanied by a commensurate decrease in propane prices would have an adverse effect on our cash flow and our ability to make quarterly distributions. If propylene prices fall significantly, we may not generate sufficient revenue to operate profitably or cover our costs, and our ability to make quarterly distributions would be materially adversely affected. Similarly, if our customers nominate at the lower end of their required minimum offtake volumes and we are unable to sell sufficient quantities of our excess supply into the spot market, we may not generate sufficient sales to operate profitably or cover our costs, and our ability to make quarterly distributions will be materially adversely affected.

Our results of operations, financial condition and ability to make cash distributions to our unitholders may be adversely affected by the supply and price levels of propane.

        The sole feedstock used in our production is propane. The price of propane is correlated to the price of crude oil and is influenced by the price of natural gas. The prices for crude oil and natural gas are cyclical and volatile, and as a result, the price of propane can be cyclical and volatile. The propane export market may also impact the price of propane. According to the U.S. Energy Information Administration, propane exports increased significantly during 2013.

        The cost of propane represents a substantial portion of our cost of sales. If propane costs increase, the market price of propylene may not rise correspondingly or at all. Timing differences between propane prices, which may change daily, and the market price of propylene, which is set monthly, may narrow the propane-to-propylene spread and thus reduce our cash flow, which reduction could be material. Based on our current output, we obtain all of the propane we need from Enterprise through its propane pipeline system, which is connected to the natural gas liquids and refined products storage hub at Mt. Belvieu. The price that we pay Enterprise for propane fluctuates based on market prices. Propane prices could significantly increase in the future. In addition, following the expiration of our

E-14


current propane supply contract, the price of storage and transportation of propane to our site is subject to change and could adversely impact our financial results.

Significant price volatility or interruptions in supply of other raw materials, such as natural gas, electricity and nitrogen, may result in increased costs that we may be unable to pass on to our customers, which could reduce our profitability.

        The raw materials we consume, such as natural gas, electricity and nitrogen, are generally commodity products that are readily available at market prices. We generally enter into supply agreements with particular suppliers, but disruptions of existing supply arrangements could substantially impact our profitability. If certain of our suppliers are unable to meet their obligations under present supply agreements, we may be forced to pay higher prices to obtain the necessary materials from other sources. In addition, if any of the raw materials that we use become unavailable within the geographic area from which they are now sourced, then we may not be able to obtain suitable or cost effective substitutes. Any interruption in the supply of raw materials will increase our costs or decrease our sales, which will reduce our cash flow.

        Our supply agreements typically provide for market-based pricing and provide us no protection against price volatility. If the cost of any of our raw materials rises, the market price of propylene may not rise correspondingly or at all. Timing differences between raw material prices, which may change daily, and the market price of propylene, which is set monthly, may have a negative effect on our cash flow. Any cost increase could have a material adverse effect on our business, results of operations, financial condition and liquidity.

Our operations are dependent on third-party suppliers, including Enterprise, which owns the propane pipeline that provides propane to our facility. The inability of a third-party supplier to perform in accordance with its contractual obligations or an election by any of our suppliers not to renew our supply contracts on comparable terms could have a material adverse effect on our results of operations, financial condition and our ability to make cash distributions to our unitholders.

        Our operations depend in large part on the performance of third-party suppliers, including Enterprise for the supply of propane, a subsidiary of Kinder Morgan Energy Partners, L.P. (or "Kinder Morgan"), for the supply of natural gas and Praxair for the supply of nitrogen. Should Enterprise, Kinder Morgan, Praxair or any of our other third-party suppliers fail to perform in accordance with existing contractual arrangements, we could be forced to halt operations at our facility. Alternative sources of supply could be difficult or impossible to obtain. Any shutdown of our operations, even for a limited period, could have a material adverse effect on our results of operations, financial condition and ability to make cash distributions to our unitholders.

        When our current supply contracts expire, we may be unable to obtain extensions or replacement contracts on substantially similar terms. If we are unable to find replacement contracts on terms as favorable as our current supply contracts, our business, results of operations, financial condition and our ability to pay cash distributions to our unitholders may be materially adversely affected.

Our facility faces (and the facilities of our suppliers and customers face) operating hazards and interruptions, including planned and unplanned maintenance or downtime. We could face potentially significant costs to the extent these hazards or interruptions cause a material decline in production.

        Our operations, located at a single location, are subject to significant operating hazards and interruptions. Any significant curtailing of production at our facility could result in materially lower levels of sales and cash flow for the duration of any shutdown and materially adversely impact our ability to make cash distributions to our unitholders. Operations at our facility could be curtailed or partially or completely shut down, temporarily or permanently, as the result of a number of

E-15


circumstances, most of which are not within our control. With respect to planned downtime, during the fourth quarter of 2013, we completed our first plant turnaround which required us to bring the plant down for 32 days to replace the reactor catalyst and perform major maintenance on equipment to help ensure the long-term reliability of plant operations. With respect to unplanned downtime, in December of 2012, our facility experienced a mechanical failure in one of our compressors, which required approximately three weeks to repair. We plan to bring the facility down in March of 2014 for approximately eight days in order to replace two heat exchangers and perform additional work. Other scenarios that could result in a shutdown of our facility include:

        The magnitude of the effect on us of any shutdown will depend on the length of the shutdown and the extent of the facility operations affected by the shutdown. A major accident, fire, flood or other event could damage our facility or the environment and the surrounding community or result in injuries or loss of life. Planned and unplanned maintenance could reduce our net income, cash flow and ability to make cash distributions during the period of time that any of our units is not operating. Any planned and unplanned future downtime could have a material adverse effect on our ability to make cash distributions to our unitholders.

        Many of the factors described above could also affect the facilities of any of our suppliers or customers. Any significant downtime affecting a material supplier or customer could also have a material adverse effect on our operations with a resulting impact on our ability to make cash distributions to our unitholders.

        Our facility requires a planned maintenance turnaround approximately every three years, which could have a material impact on our cash flows and ability to make cash distributions in the quarter or quarters in which it occurs. Our turnaround in 2013 lasted 32 days. We assume future turnarounds will be of a similar duration, provided the actual duration will be dependent upon the scope of any additional work we elect to perform.

        Based upon the decision(s) made by the board of directors of our General Partner, the cash available for distribution in the quarter(s) preceding such a planned maintenance event may be adversely impacted by the amount of reserves the board of directors of our General Partner establishes to fund the cost of the planned maintenance event. In the period preceding our 2013 turnaround, the board of directors of our General Partner reserved $77.0 million to fund: (i) capital costs associated with the change-out of our reactor catalyst described elsewhere in this annual report, (ii) other capital and maintenance projects completed as part of the turnaround and (iii) all or a portion of the projected lost margin due to the purchase of propylene as inventory for sales to our customers during the turnaround. Additional amounts may be required to be reserved from available cash generated in a quarter subsequent to such a planned maintenance event should the scope of the actual work performed during such period be materially different than that planned.

E-16


We are not fully insured against all risks incident to our business, and if an accident or event occurs that is not fully insured it could adversely affect our business.

        A major accident, fire, flood or other event could damage our facility or the environment and the surrounding community or result in injuries or loss of life. If we experience significant property damage, business interruption, environmental claims or other liabilities, our business could be materially adversely affected to the extent the damages or claims exceed the amount of valid and collectible insurance available to us. We are currently insured under property, business interruption, general liability (including sudden and accidental pollution liability), business automobile, workers compensation and excess liability insurance policies. The property and business interruption insurance policies have a $1.0 billion single occurrence limit with a $1.0 million deductible for physical damage and a 60-day waiting period before losses resulting from business interruptions are recoverable. The policies also contain exclusions and conditions that could have a materially adverse impact on our ability to receive indemnification thereunder, as well as customary sub-limits for particular types of losses. For example, the current property policy contains specific sub-limits of $400.0 million for damage caused by flooding and $100.0 million for damage caused by named windstorms, with deductibles of $1.0 million and $5.0 million per occurrence, respectively. We are fully exposed to all losses in excess of the applicable limits and sub-limits and for losses due to business interruptions of fewer than 60 days. In addition, our insurance portfolio does not cover all of the operating risks that we face. For example, we do not carry contingent business interruption insurance, which would reimburse us for the lost profits and expenses that resulted from an insurable loss suffered by one or more of our customers or suppliers. The occurrence of any operating risk not covered by our insurance could have a material adverse effect on our business, financial condition, results of operations and ability to pay distributions to our unitholders. Our general liability insurance policy, which includes sudden and accidental pollution coverage expires on March 1, 2015, and our property and business interruption insurance policies expire on May 1, 2014. We are currently in negotiations with our underwriters as to the extension of our property and business interruption insurance policies. Market factors, including but not limited to catastrophic perils that impact our industry, significant changes in the investment returns of insurance companies, insurance company solvency trends and industry loss ratios and loss trends, can negatively impact the future cost and availability of insurance. There can be no assurance that we will be able to buy and maintain insurance in the future with adequate limits, reasonable pricing terms and conditions.

We have a limited operating history during which we have experienced both planned and unplanned downtime. As a result, you may have difficulty evaluating our ability to pay quarterly cash distributions to our unitholders or our ability to be successful in implementing our business strategy.

        We are dependent on our facility as our sole source of propylene and by-products to generate sales, and we are, therefore, dependent on the continued operation of this facility to generate our sales. As a newly constructed complex processing facility, the operating performance of our facility over the long-term is not yet proven. We have already encountered and will continue to encounter risks and difficulties frequently experienced by companies whose performance is dependent upon newly constructed world-scale processing or manufacturing facilities, such as the risks described in this report.

        Our customer contracts provide for potential maximum offtake volumes of approximately 1.4 billion pounds of propylene per year. To the extent that our supply obligations under our customer contracts exceed the volume that we can produce and the volume we have in inventory, we may need to purchase propylene from third parties in the spot market. In periods of extended planned or unplanned downtime, we may be required to purchase significant volumes of propylene in order to satisfy our contractual obligations, which could materially and adversely affect our profitability and our ability to make cash distributions to our unitholders. Further, if we were unable to purchase the

E-17


volumes of propylene necessary to satisfy our contractual obligations, we may be in default of our customer contracts.

        Because of our limited operating history and performance record, it is difficult for you to evaluate our business and results of operations to date and to assess our future prospects. Further, our historical financial statements present a period of limited operations, and therefore do not provide a meaningful basis for you to evaluate our operations or our ability to achieve our business strategy. We may be less successful than a seasoned company in achieving a consistent operating level at our facility capable of generating cash flows from our operations sufficient to regularly pay a quarterly cash distribution or to pay any quarterly cash distribution to our unitholders. We may also be less successful in implementing our business strategy than a seasoned company with a longer operating history. Finally, we may be less equipped to identify and address operating risks and hazards in the conduct of our business than those companies whose major facilities have longer operating histories.

We face competition from other propylene producers.

        We consider companies with net long positions in propylene to be our direct competitors, including Enterprise, Chevron Phillips, ExxonMobil Chemical, Shell Chemical, Flint Hills and the Williams Companies. Most of our competitors have significantly greater financial and other resources than us and are engaged on a national or international basis in many segments of the petroleum products and petrochemicals business, including refining, transportation and marketing, on a scale substantially larger than ours. In addition, we may face competition from captive propylene production facilities operated by consumers of propylene, including our customers. Further, it is likely that in future years, competition will come from the construction of additional on-purpose propylene facilities. As a result of these factors, we may be unable to expand our relationships with existing customers or to obtain new customers on a profitable basis, or at all, which would have a material adverse effect on our business, results of operations and financial condition and our ability to pay cash distributions to our unitholders.

We depend on certain third-party pipelines to supply us with feedstock and to distribute propylene to our customers. If these pipelines become unavailable to us, our business could be adversely affected.

        Our ability to obtain propane and other inputs necessary for the production of propylene is dependent upon the availability of third-party pipeline systems interconnected to our facility. In addition, we depend in part on third-party pipeline systems to transport propylene to our customers. Because we do not own these pipelines, their continuing operation is not within our control. These pipelines and the pipelines we own may become unavailable for a number of reasons, including testing, maintenance, capacity constraints, accidents, government regulation or other events. If any of such pipelines become partially or completely unavailable, our ability to operate could be restricted and our transportation costs could increase, thereby reducing our profitability. A prolonged or permanent interruption in the availability of third-party or our own pipelines could have a material adverse effect on our business, financial condition, results of operations and ability to pay distributions to our unitholders.

The growth in production of natural gas from shale formations, which is expected to lead to an increased supply of propane, may not continue at projected rates due to the uncertainty associated with the length of their production lives, legislative initiatives restricting such production, or both.

        Hydraulic fracturing is a process used by oil and natural gas exploration and production operators in the completion of certain oil and natural gas wells whereby water, sand and chemicals are injected under pressure into subsurface formations to stimulate natural gas production. The proliferation of hydraulic fracturing has led to a marked growth in production of natural gas and the resulting abundance of natural gas has led to a decrease in price. However, production of gas from shale formations is in its nascence, and certain industry reports have indicated that the wells may have

E-18


shorter economically-viable production lives than previously anticipated. If such reports are accurate, shale gas development and production may be negatively impacted, which may lead to substantial increases in natural gas prices.

        Although hydraulic fracturing has been used for decades in connection with conventional or vertical wells, its use has expanded substantially in recent years as the application of hydraulic fracturing on horizontal wells drilled to produce from shale formations has expanded substantially. This expanded use of hydraulic fracturing has recently attracted increased scrutiny from federal and state officials for its potential impact on health and the environment. Adoption of legislation or any implementation of regulations placing restrictions on hydraulic fracturing activities could make it more difficult to perform hydraulic fracturing, resulting in a reduction in the supply of natural gas and an increase in the price of natural gas.

        An increase in the price of natural gas could narrow the propane-to-propylene spread in two ways, each adversely affecting our gross margins. First, a significant increase in natural gas prices could be accompanied by an increase in the price of NGLs such as ethane. An increase in ethane prices could cause ethylene producers to favor the use of naphtha as a feedstock. Because the use of naphtha as a feedstock in the ethylene production process results in significantly more propylene as co-product than ethane, the result would be an increase in propylene production by ethylene plants. The increased supply of propylene would in turn exert downward pressure on the price of propylene, adversely affecting the price we obtain for the propylene we produce, both in the spot market and pursuant to our customer contracts, which are market-based.

        Second, an increase in the price of natural gas may be accompanied by an increase in the price of propane, as the majority of propane is derived from natural gas production, thereby further narrowing the propane-to-propylene spread and reducing our gross margins.

We currently derive substantially all of our sales from five customers, and the loss of any of these customers without replacement on comparable terms would affect our results of operations and cash available for distribution to our unitholders.

        We have derived, and believe that we will continue to derive, substantially all of our sales from a limited number of customers that purchase all of the propylene we produce. For the year ended December 31, 2013, Dow, Total, INEOS, BASF, and LyondellBasell accounted for 44%, 21%, 18%, 9% and 6% of our total sales, respectively. When our current contracts with these customers expire, our customers may decide not to extend the contracts or may decide to purchase fewer pounds of propylene at lower prices during renegotiations. If at the end of their respective contract terms our customers decide not to renew these contracts, or decide to purchase fewer pounds of propylene or at lower prices, and we are unable to find replacement counterparties on terms as favorable as our current contracts, our business, results of operations, financial condition and our ability to pay cash distributions to our unitholders may be materially adversely affected. During 2013, we amended our contracts with Total, INEOS and BASF to extend the contract terms. Our multi-year propylene supply contracts expire between 2016 and 2018. Also during 2013, we amended our contract with LyondellBasell to extend the term to December 2014.

We are subject to many environmental and safety regulations that may result in unanticipated costs or liabilities, which could reduce our profitability.

        We are subject to extensive federal, state and local laws, regulations, rules and ordinances relating to pollution, protection of the environment and human health, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or

E-19


prohibitions on facility operations, substantial civil or criminal sanctions, as well as, under some environmental laws, the assessment of strict liability and/or joint and several liability.

        Continually increasing concerns regarding the safety of chemicals in commerce and their potential impact on the environment constitute a growing trend. Governmental, regulatory and societal demands for continuously increasing levels of product safety and environmental protection could result in continued pressure for more stringent regulatory control with respect to the chemical industry. In addition, these concerns could influence public perceptions, the viability of certain products, our reputation, the cost to comply with regulations and the ability to attract and retain employees. Moreover, changes in environmental regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur significant unanticipated losses, costs or liabilities, which could reduce our profitability.

        We could incur significant expenditures in order to comply with existing or future environmental or safety laws. Capital expenditures and costs relating to environmental or safety matters will be subject to evolving regulatory requirements and will depend on the timing of the promulgation and enforcement of specific standards which impose requirements on our operations. Capital expenditures and costs beyond those currently anticipated may therefore be required under existing or future environmental or safety laws.

        Furthermore, we may be liable for the costs of investigating and cleaning up environmental contamination on or from our properties or at off-site locations where we disposed of or arranged for the disposal or treatment of hazardous materials or from disposal activities that pre-dated our purchase of the facility. We may, therefore, incur additional costs and expenditures beyond those currently anticipated to address all such known and unknown situations under existing and future environmental laws.

Climate change laws and regulations could have a material adverse effect on our results of operations, financial condition and ability to pay cash distributions to our unitholders.

        Federal climate change legislation in the United States appears unlikely in the near-term. As a result, domestic efforts to curb greenhouse gas emissions continue be led by the EPA's greenhouse gas regulations and the efforts of states. To the extent that our domestic operations are subject to the EPA's greenhouse gas regulations, we may face increased capital and operating costs associated with new or expanded facilities. Significant expansions of our existing facility or construction of new facilities may be subject to the CAA's PSD requirements under the EPA's greenhouse gas "Tailoring Rule."

        Under a consent decree with states and environmental groups, the EPA is due to propose NSPS for greenhouse gas emissions from refineries. These standards could significantly increase the costs of constructing or adding capacity to refineries and may ultimately increase the costs or decrease the supply of refined products. Either of these events could have an adverse effect on our business.

        It is possible that greenhouse gas emission restrictions may increase over time. Potential consequences of such restrictions include capital costs to modify operations as necessary to meet greenhouse gas emission limits and/or additional energy costs, as well as direct compliance costs. Currently, however, it is not possible to estimate the likely financial impact of potential future regulation on our operations.

        Finally, it should be noted that some scientists have concluded that increasing concentrations of greenhouse gases in the earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, floods and other climatic events. If any of those effects were to occur, they could have an adverse effect on our facilities and operations.

        Please read " Environmental Matters—Climate Change " above for a more detailed discussion.

We are subject to strict laws and regulations regarding employee and process safety, as well as the prevention of accidental releases, and failure to comply with these laws and regulations could have a material adverse effect on our results of operations, financial condition and ability to pay cash distributions to our unitholders.

        Our facility is subject to the requirements of OSHA and comparable state statutes that regulate the protection of the health and safety of workers. OSHA requires that we maintain information about hazardous materials used or produced in our operations and that we provide this information to employees, state and local governmental authorities and local residents. In addition, the Chemical Accident Prevention Provisions adopted by the EPA under the CAA require the development of a Risk Management Plan to prevent the accidental release of hazardous substances that could harm public health or the environment. Failure to comply with these requirements, including general industry standards, record keeping requirements and monitoring and control of potential exposure to regulated substances, could have a material adverse effect on our results of operations, financial condition and ability to pay cash distributions to our unitholders if we are subjected to significant fines or compliance costs.

Instability and volatility in the global capital and credit markets could negatively impact our business, financial condition, results of operations and cash flows.

        The global capital and credit markets have experienced extreme volatility and disruption over the past few years. Our results of operations, financial condition and ability to pay cash distributions to our unitholders could be negatively impacted by difficult conditions and extreme volatility in the capital, credit and commodities markets and in the global economy. These factors, combined with declining business and consumer confidence and increased unemployment, precipitated an economic recession in the U.S. and globally during 2009 and 2010. The difficult conditions in these markets and the overall economy affect us in a number of ways. For example:

We depend on key personnel for the success of our business.

        We depend on the services of the executive officers and other key personnel of our General Partner. The loss of the services of any member of our executive officer team or key employee could have an adverse effect on our business and reduce our ability to make distributions to our unitholders. Many of our key employees and management members, including our Executive Chairman and President and Chief Executive Officer, were involved with the development of our facility and thus possess extensive knowledge of our business. We may not be able to locate or employ on acceptable terms qualified replacements for senior management or other key employees if their services were no longer available.

E-21


Certain members of our executive management team on whom we rely to manage important aspects of our business may face conflicts regarding the allocation of their time.

        We rely on the executive officers and employees of our General Partner to manage our operations and activities. Under our partnership agreement, the employees and executive officers of our General Partner may, from time to time, provide management, advisory and administrative services to its affiliates and other persons. As a result of the foregoing, such employees and executive officers may face conflicts regarding the allocation of their time, which may adversely affect our business, results of operations and financial condition.

A shortage of skilled labor, together with rising labor costs, could adversely affect our results of operations and cash available for distribution to our unitholders.

        The efficient production of propylene using modern techniques and equipment requires skilled employees. Our facility relies on technology that requires special expertise to operate efficiently and effectively. To the extent that the services of our key technical personnel become unavailable to us for any reason, we would be required to hire other personnel. We may not be able to locate or employ such qualified personnel on acceptable terms or at all. We face competition for these professionals from our competitors, our customers and other companies operating in our industry. If we are unable to find qualified employees, or if the cost to find qualified employees increases materially, our results of operations and cash available for distribution to our unitholders could be adversely affected.

Restrictions in the agreements governing our current and future indebtedness, including our credit facilities, contain or will contain significant limitations on our business operations, including our ability to pay distributions and other payments.

        On March 28, 2013, we and our wholly-owned finance subsidiary, PetroLogistics Finance Corp., co-issued jointly and severally $365.0 million of senior unsecured notes due 2020 (or the "senior notes"), and we entered into an amended and restated credit agreement which extended our revolving credit facility from $120 million to $170 million with Morgan Stanley Senior Funding, Inc. (or the "Agent"), and the lender parties thereto. As of February 28, 2014, we had $365.0 million of senior notes outstanding and borrowing capacity of approximately $170 million under our revolving credit facility. We and our subsidiary may incur significant additional indebtedness in the future. Our ability to pay distributions to our unitholders and our ability to borrow under these credit facilities to fund distributions (if we elect to do so) is subject to covenant restrictions under the agreement governing the credit facilities. We expect that our ability to make distributions to our common unitholders will depend, in part, on our ability to satisfy applicable covenants as well as the absence of a default or event of default under the facilities. If we were unable to comply with any such covenant restrictions in any quarter, our ability to pay distributions to unitholders would be curtailed or eliminated.

        In addition, we will be subject to covenants contained in our credit facilities, the indenture governing our senior notes and any agreement governing other future indebtedness that will, subject to significant exceptions, limit our ability and the ability of our operating subsidiary to, among other things: incur, assume or permit to exist additional indebtedness, guarantees and other contingent obligations, incur liens, make negative pledges, pay dividends or other distributions, make payments to our subsidiary, make certain loans and investments, consolidate, merge or sell all or substantially all of our assets. Any failure to comply with these covenants could result in a default under our credit facilities or the indenture governing our senior notes. Upon a default, unless waived, the lenders under our credit facilities would have all remedies available to a secured lender and could elect to terminate their commitments, cease making further loans, cause their loans to become due and payable in full, institute foreclosure proceedings against our or our subsidiary's assets and force us and our subsidiary into bankruptcy or liquidation.

E-22


Any increase in market interest rates would make our debt service obligations more burdensome, and in turn reduce our cash available for distributions to our unitholders.

        Borrowings under our revolving credit facility bear interest at variable rates. If market interest rates increase, such variable-rate debt will create higher debt service requirements, which could adversely affect our cash flow and ability to pay cash distributions to our unitholders.

        Borrowings under our credit facilities bear interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the term loan and the revolving credit facility ranges from 2.0% for loans bearing interest at the Alternate Base Rate to 3.0% for loans bearing interest at LIBOR.

        Our ability to make scheduled debt payments, to refinance our obligations with respect to our indebtedness and to fund capital and non-capital expenditures necessary to maintain the condition of our operating assets, properties and systems software, as well as to provide capacity for the growth of our business, depends on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and financial, business, competitive, legal and other factors.

        If our operating results are not sufficient to service our current or future indebtedness, we will be forced to take actions such as reducing or eliminating distributions, reducing or delaying our business activities, acquisitions, investments or capital expenditures, selling assets, restructuring or refinancing our debt, or seeking additional equity capital or bankruptcy protection.

Increases in interest rates could adversely impact our unit price and our ability to issue additional equity to make acquisitions, incur debt or for other purposes.

        We cannot predict how interest rates will react to changing market conditions. Interest rates on our credit facilities, future credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly. Additionally, as with other yield-oriented securities, we expect that our unit price will be impacted by the level of our quarterly cash distributions and implied distribution yield. The distribution yield is often used by investors to compare and rank related yield-oriented securities for investment decision-making purposes. Therefore, changes in interest rates may affect the yield requirements of investors who invest in our common units, and a rising interest rate environment could have a material adverse impact on our unit price and our ability to issue additional equity to fund our operations or to make acquisitions or to incur debt as well as increasing our interest costs.

We are a holding company and depend upon our subsidiary for our cash flow.

        We are a holding company. All of our operations are conducted and all of our assets are owned by PL Propylene, our wholly-owned subsidiary and our sole direct or indirect operating subsidiary. Consequently, our cash flow and our ability to meet our obligations or to pay cash distributions to our unitholders in the future will depend upon the cash flow of PL Propylene and the payment of funds by PL Propylene to us in the form of dividends or otherwise. The ability of PL Propylene to make any payments to us will depend on its earnings, the terms of its indebtedness, including the terms of any credit facilities, and legal restrictions. In particular, future credit facilities incurred at PL Propylene may impose significant limitations on the ability of PL Propylene to pay distributions to us and consequently our ability to pay distributions to our unitholders. See also "—We may not have sufficient available cash to pay any quarterly distribution on our common units."

As a publicly traded partnership we qualify for, and rely on, certain exemptions from the New York Stock Exchange's corporate governance requirements.

        As a publicly traded partnership, we qualify for, and rely on, certain exemptions from the NYSE's corporate governance requirements, including:

        As a result of these exemptions, our General Partner's board of directors is not comprised of a majority of independent directors, our General Partner's compensation committee is not comprised entirely of independent directors and our General Partner's board of directors does not currently intend to establish a nominating/corporate governance committee. Accordingly, unitholders will not have the same protections afforded to equityholders of companies that are subject to all of the corporate governance requirements of the NYSE. See "Item 10. Directors, Executive Officers and Corporate Governance—Our Management."

Risks Related to an Investment in Us

The board of directors of our General Partner has adopted a policy to distribute all of the available cash we generate each quarter, which could limit our ability to grow and make acquisitions.

        The board of directors of our General Partner has adopted a policy to distribute all of the available cash we generate each quarter to our unitholders. As a result, our General Partner will rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. As such, to the extent we are unable to finance growth externally, our cash distribution policy will significantly impair our ability to grow.

        In addition, because the board of directors of our General Partner has adopted a policy to distribute all of the available cash we generate each quarter, our growth may not be as robust as that of businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units will decrease the amount we distribute on each outstanding unit. There are no limitations in our partnership agreement on our ability to issue additional units, including units ranking senior to the common units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, would reduce the available cash that we have to distribute to our unitholders. See "Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Securities—Our Cash Distribution Policy."

Our General Partner, which is indirectly owned by funds controlled by Lindsay Goldberg and York Capital, has fiduciary duties to Lindsay Goldberg and York Capital, and the interests of Lindsay Goldberg and York Capital may differ significantly from, or conflict with, the interests of our public common unitholders.

        Our General Partner is responsible for managing us. Although our General Partner has legal duties to manage us in good faith, these duties are specifically limited by the express terms of our partnership agreement, and the directors and officers of our General Partner also have fiduciary duties to manage our General Partner in a manner beneficial to Lindsay Goldberg and York Capital, which

E-24


collectively own 84% of our General Partner. The interests of Lindsay Goldberg and York Capital may differ from, or conflict with, the interests of our common unitholders. In resolving these conflicts, our General Partner may favor its own interests or the interests of Lindsay Goldberg and York Capital over our interests and those of our common unitholders.

        The potential conflicts of interest include, among others, the following:

Our partnership agreement limits the liability and duties of our General Partner and restricts the remedies available to us and our common unitholders for actions taken by our General Partner that might otherwise constitute breaches of fiduciary duty.

        Fiduciary duties are generally considered to include an obligation to act in good faith and with due care and loyalty. The duty of care, in the absence of a provision in a partnership agreement providing otherwise, would generally require a general partner to act for the partnership in the same manner as a prudent person would act on his own behalf. The duty of loyalty, in the absence of a provision in a partnership agreement providing otherwise, would generally require that any action taken or transaction engaged in be entirely fair to the Partnership.

        Our partnership agreement limits the liability and duties of our General Partner, while also restricting the remedies available to our common unitholders for actions that, without these limitations and reductions, might constitute breaches of fiduciary duty. Delaware partnership law permits such

E-25


contractual reductions of fiduciary duty. By purchasing common units, common unitholders consent to be bound by the partnership agreement, and pursuant to our partnership agreement, each holder of common units consents to various actions and conflicts of interest contemplated in our partnership agreement that might otherwise constitute a breach of fiduciary or other duties under Delaware law. Our partnership agreement contains provisions that reduce the standards to which our General Partner would otherwise be held by state fiduciary duty law. For example:

        In connection with a situation involving a transaction with an affiliate or a conflict of interest, any determination by our General Partner must be made in good faith. Our partnership agreement generally provides that affiliated transactions and resolutions of conflicts of interest not involving a vote of unitholders and that are not approved by the conflicts committee of the board of directors of our General Partner must be:

        If our General Partner does not seek approval from the conflicts committee of its board of directors or the common unitholders, and its board of directors determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the bullet points above, then it will be presumed that, in making its decision, the board of directors, which may include board members affected by the conflict of interest, acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the Partnership, the person bringing or

E-26


prosecuting such proceeding will have the burden of overcoming such presumption. These standards reduce the obligations to which our General Partner would otherwise be held.

        By purchasing a common unit, a unitholder will become bound by the provisions of our partnership agreement, including the provisions described above.

Our sponsors have the power to appoint and remove our General Partner's directors.

        Our sponsors have the power to elect all of the members of the board of directors of our General Partner. Our General Partner has control over all decisions related to our operations. See "Item 10. Directors, Executive Officers and Corporate Governance—Our Management."

        Our public unitholders do not have an ability to influence any operating decisions and will not be able to prevent us from entering into any transactions. Furthermore, the goals and objectives of our sponsors, as the owner of our General Partner, may not be consistent with those of our public unitholders.

Common units are subject to our General Partner's call right.

        If at any time our General Partner and its affiliates own more than 80% of the common units, our General Partner will have the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by public unitholders at a price not less than their then-current market price, as calculated pursuant to the terms of our partnership agreement. As a result, you may be required to sell your common units at an undesirable time or price and may not receive any return on your investment. You may also incur a tax liability upon a sale of your common units. Our General Partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the call right. There is no restriction in our partnership agreement that prevents our General Partner from issuing additional common units and then exercising its call right. Our General Partner may use its own discretion, free of fiduciary duty restrictions, in determining whether to exercise this right.

Our unitholders have limited voting rights and are not entitled to elect our General Partner or our General Partner's directors.

        Unlike the holders of common stock in a corporation, our unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management's decisions regarding our business. Unitholders will have no right to elect our General Partner or our General Partner's board of directors on an annual or other continuing basis. The board of directors of our General Partner, including the independent directors, will be chosen entirely by our sponsors as the owner of the General Partner and not by our common unitholders. Unlike publicly traded corporations, we will not hold annual meetings of our unitholders to elect directors or conduct other matters routinely conducted at annual meetings of stockholders. Furthermore, even if our unitholders are dissatisfied with the performance of our General Partner, they will have no practical ability to remove our General Partner. As a result of these limitations, the price at which the common units will trade could be diminished.

Our public unitholders do not have sufficient voting power to remove our General Partner without our sponsors' consent.

        Our sponsors own approximately 63% of our common units, which means holders of common units are not able to remove the General Partner, under any circumstances, unless our sponsors sell some of the common units that they own or we sell additional units to the public.

E-27


Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units (other than our General Partner and its affiliates and permitted transferees).

        Our partnership agreement restricts unitholders' voting rights by providing that any units held by a person that owns 20% or more of any class of units then outstanding, other than our General Partner, its affiliates, their transferees and persons who acquired such units with the prior approval of the board of directors of our General Partner, may not vote on any matter. Our partnership agreement also contains provisions limiting the ability of common unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting the ability of our common unitholders to influence the manner or direction of management.

Cost reimbursements due to our General Partner and its affiliates will reduce cash available for distribution to you.

        Prior to making any distribution on our outstanding units, we will reimburse our General Partner for all expenses it incurs on our behalf including, without limitation, salary, bonus, incentive compensation and other amounts paid to its employees and executive officers who perform services for us. There are no limits contained in our partnership agreement on the amounts or types of expenses for which our General Partner and its affiliates may be reimbursed. The payment of these amounts, including allocated overhead, to our General Partner and its affiliates could adversely affect our ability to make distributions to you.

Unitholders may have liability to repay distributions.

        In the event that: (1) we make distributions to our unitholders when our nonrecourse liabilities exceed the sum of (a) the fair market value of our assets not subject to recourse liability and (b) the excess of the fair market value of our assets subject to recourse liability over such liability, or a distribution causes such a result, and (2) a unitholder knows at the time of the distribution of such circumstances, such unitholder will be liable for a period of three years from the time of the impermissible distribution to repay the distribution under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act (or the "Delaware Act").

        Likewise, upon the winding up of the Partnership, in the event that (1) we do not distribute assets in the following order: (a) to creditors in satisfaction of their liabilities; (b) to partners and former partners in satisfaction of liabilities for distributions owed under our partnership agreement; (c) to partners for the return of their contribution; and finally (d) to the partners in the proportions in which the partners share in distributions and (2) a unitholder knows at the time of such circumstances, then such unitholder will be liable for a period of three years from the impermissible distribution to repay the distribution under Section 17-807 of the Delaware Act.

Our General Partner's interest in us and the control of our General Partner may be transferred to a third party without unitholder consent.

        Our General Partner may transfer its general partner interest in us to a third party in a merger or in a sale of all or substantially all of its assets without the consent of the unitholders. Furthermore, there is no restriction in our partnership agreement on the ability of the owners of our General Partner to transfer their equity interests in our General Partner to a third party. The new equity owner of our General Partner would then be in a position to replace the board of directors and the officers of our General Partner with its own choices and to influence the decisions taken by the board of directors and officers of our General Partner.

E-28


We may issue additional common units and other equity interests without your approval, which would dilute your existing ownership interests.

        Under our partnership agreement, we are authorized to issue an unlimited number of additional interests without a vote of the unitholders. The issuance by us of additional common units or other equity interests of equal or senior rank will have the following effects:

        the proportionate ownership interest of unitholders immediately prior to the issuance will decrease;

        In addition, our partnership agreement does not prohibit the issuance of equity interests by our subsidiary, which may effectively rank senior to the common units.

Units eligible for future sale may cause the price of our common units to decline.

        Sales of substantial amounts of our common units in the public market, or the perception that these sales may occur, could cause the market price of our common units to decline. This could also impair our ability to raise additional capital through the sale of our equity interests.

        We have 139,212,737 common units outstanding. As of March 1, 2014, 101,841,528 of such common units are owned by our sponsors and Messrs. David Lumpkins and Nathan Ticatch.

        In connection with our IPO, we entered into a registration rights agreement with David Lumpkins, Nathan Ticatch and our sponsors pursuant to which we may be required to register the sale of the common units they hold under the Securities Act and applicable state securities laws.

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, as well as our not being subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service, (or "IRS"), were to treat us as a corporation for U.S. federal income tax purposes or we were to become subject to material additional amounts of entity-level taxation for state tax purposes, then our cash available for distribution to you would be substantially reduced.

        The anticipated after-tax economic benefit of an investment in our units depends largely on our being treated as a partnership for U.S. federal income tax purposes. Despite the fact that we are organized as a limited partnership under Delaware law, we would be treated as a corporation for U.S. federal income tax purposes unless we satisfy a "qualifying income" requirement. Based upon our current operations, we believe we satisfy the qualifying income requirement. However, we have not requested, and do not plan to request, a ruling from the IRS on this or any other matter affecting us. Failing to meet the qualifying income requirement or a change in current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to taxation as an entity.

        If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate, which is currently a maximum of 35%, and would likely be liable for state income tax at varying rates. Distributions to our unitholders would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to our unitholders. Because taxes would be imposed upon us as a corporation, our cash available for distribution to our unitholders would be substantially reduced.

E-29


Therefore, our treatment as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.

        In Texas, the only state in which we currently conduct business, we are subject to an entity-level tax on any portion of our income that is generated in Texas in the prior year. Imposition of any such additional taxes on us or an increase in the existing tax rates would reduce the cash available for distribution to our unitholders. If we were to conduct business in other states in the future, we may also be subject to a material amount of entity-level taxation in such states which would reduce our cash available for distribution to our unitholders.

The tax treatment of publicly traded partnerships or an investment in our units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.

        The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. For example, from time to time, members of Congress propose and consider substantive changes to the existing U.S. federal income tax laws that affect publicly traded partnerships. One such legislative proposal would have eliminated the qualifying income exception to the treatment of all publicly traded partnerships as corporations upon which we rely for our treatment as a partnership for U.S. federal income tax purposes. We are unable to predict whether any of these changes or other proposals will be reintroduced or will ultimately be enacted. Any such changes could negatively impact the value of an investment in our common units. Any modification to U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible for us to meet the qualifying income requirement to be treated as a partnership for U.S. federal income tax purposes.

You will be required to pay taxes on your share of our income even if you do not receive any cash distributions from us.

        You will be required to pay any federal income taxes and, in some cases, state and local income taxes on your share of our taxable income whether or not you receive cash distributions from us. You may not receive cash distributions from us equal to your share of our taxable income or even equal to the actual tax liability which results from that income.

The sale or exchange of 50% or more of our capital and profits interests within a twelve-month period will result in the termination of us as a partnership for federal income tax purposes.

        We will be considered to have terminated as a partnership for federal income tax purposes if there is a sale or exchange of 50% or more of the total interests in our capital and profits within a twelve-month period. Lindsay Goldberg and York Capital Management collectively own approximately 63% of our common units. When combined with routine sales of our common units on the open market, material sales or transfers of their common units could cause a technical termination of our partnership. For purposes of determining whether the 50% threshold has been met, multiple sales of the same interest will be counted only once. Our termination would, among other things, result in the closing of our taxable year for all unitholders, which would result in our filing two tax returns for one calendar year and could result in a significant deferral of depreciation deductions allowable in computing our taxable income. In the case of a unitholder reporting on a taxable year other than a calendar year, the closing of our taxable year may also result in more than twelve months of our taxable income or loss being includable in taxable income for the unitholder's taxable year that includes our termination. Our termination would not affect our classification as a partnership for federal income tax purposes, but it would result in our being treated as a new partnership for U.S. federal income tax

E-30


purposes following the termination. If we were treated as a new partnership, we would be required to make new tax elections and could be subject to penalties if we were unable to determine that a termination occurred. The IRS recently announced a relief procedure whereby if a publicly traded partnership that has technically terminated requests and the IRS grants special relief, among other things, the partnership may be permitted to provide only a single Schedule K-1 to unitholders for the two short tax periods included in the year in which the termination occurs.

Tax gain or loss on the disposition of our common units could be more or less than expected.

        If you sell your common units, you will recognize a gain or loss equal to the difference between the amount realized and your tax basis in those common units. Because distributions in excess of your allocable share of our net taxable income decrease your tax basis in your common units, the amount, if any, of such prior excess distributions with respect to the units you sell will, in effect, become taxable income to you if you sell such units at a price greater than your tax basis in those units, even if the price you receive is less than your original cost. Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if you sell your units, you may incur a tax liability in excess of the amount of cash you receive from the sale.

Tax-exempt entities and non-U.S. persons face unique tax issues from owning common units that may result in adverse tax consequences to them.

        Investment in common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (or "IRAs"), and non-U.S. persons raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. Distributions to non-U.S. persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to file U.S. federal tax returns and pay tax on their share of our taxable income. If you are a tax-exempt entity or a non-U.S. person, you should consult your tax advisor before investing in our common units.

If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contest will reduce our cash available for distribution to you.

        The IRS may adopt positions that differ from the positions we take. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for our common units and the price at which they trade. Our costs of any contest with the IRS will be borne indirectly by our unitholders and our General Partner because the costs will reduce our cash available for distribution.

We will treat each purchaser of our common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

        Because we cannot match transferors and transferees of common units and because of other reasons, we will adopt depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to you. It also could affect the timing of these tax benefits or the amount of gain from your sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to your tax returns.

E-31


We will prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.

        We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our common units each month based upon the ownership of our common units on the first day of each month, instead of on the basis of the date a particular common unit is transferred. Nonetheless, we allocate certain deductions for depreciation of capital additions based upon the date the underlying property is placed in service. The use of this proration method may not be permitted under existing Treasury Regulations, and although the U.S. Treasury Department issued proposed Treasury Regulations allowing a similar monthly simplifying convention, such regulations are not final and do not specifically authorize the use of the proration method we have adopted. Accordingly, our counsel is unable to opine as to the validity of this method. If the IRS were to successfully challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

A unitholder whose units are the subject of a securities loan (e.g., a loan to a "short seller" to cover a short sale of units) may be considered as having disposed of those units. If so, he would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition.

        Because there are no specific rules governing the U.S. federal income tax consequence of loaning a partnership interest, a unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, the unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities loan are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their units.

Unitholders may be subject to state and local taxes and return filing requirements in jurisdictions where they do not live as a result of investing in our common units.

        In addition to federal income taxes, unitholders may become subject to other taxes, including state, local and non-U.S. taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by jurisdictions in which we conduct business or own property in the future, even if they do not live in any of those jurisdictions. We currently conduct business only in Texas, which does not impose a personal income tax but does impose a tax on corporations and other entities. However, we may own property or conduct business in other states or non-U.S. countries in the future. Unitholders may be required to file state and local income tax returns and pay state and local income taxes in some or all of those various jurisdictions. Further, unitholders may be subject to penalties for failure to comply with those requirements. It is the unitholder's responsibility to file all U.S. federal, state, local and non-U.S. tax returns.

Item 3.    Legal Proceedings.

        We are, and will continue to be, subject to litigation from time to time in the ordinary course of our business. On March 4, 2014, we received notice of a lawsuit filed on behalf of Anthony Garza against us and one other party in the District Court of Harris County, Texas, 151st Judicial District, at case number 2014-09650 for liability involving personal injuries sustained in February 2014 by Mr. Garza, an employee of one or our contractors, while working at our facility. The plaintiff makes a number of allegations including a claim that the defendants breached a duty of care owing to the plaintiff. Our contract with the contractor contains an obligation on the contractor to indemnify and defend us with respect to matters of this nature. We also carry general liability insurance, subject to a deductible. We do not expect the cost of a settlement or eventual judgment, if any, to be material to our financial position or results of operations.

(2)
Represents the period from May 4, 2012, the date on which our common stock began trading on the NYSE, through June 30, 2012.

        Our common units are used as a form of compensation to our employees. Additional information regarding our equity compensation plans is included in Part III of this report under "Item 13. Certain Relationships and Related Transactions and Director Independence."

        The number of holders of record of our common units was 15 on March 1, 2014. The number of record holders does not include holders of shares in "street names" or persons, partnerships, associations, corporations or other entities identified in security position listings maintained by depositories.

        The board of directors of our General Partner has adopted a policy pursuant to which we will distribute all of the available cash we generate each quarter. Available cash for each quarter will be determined by the board of directors of our General Partner following the end of such quarter. We expect that available cash for each quarter will generally equal our cash flow from operations for the quarter less cash needed for capital expenditures, debt service and other contractual obligations, reserves to fund quarterly distributions to our unitholders during future periods associated with our planned triennial maintenance turnarounds, and reserves for future operating or capital needs that the board of directors of our General Partner deems necessary or appropriate. Except in connection with our triennial maintenance projects, we do not intend to maintain excess distribution coverage or reserve cash for the purpose of maintaining stability or growth in our quarterly distribution. We do not intend

E-34


to incur debt to pay quarterly distributions. We expect to finance substantially all of our material growth opportunities through issuances of either debt or equity.

        Because our policy is to distribute all available cash we generate each quarter, our unitholders will have direct exposure to fluctuations in the amount of cash generated by our business. We expect that the amount of our quarterly distributions, if any, will vary based on our operating cash flow during each quarter. Though such variations will be mitigated in respect of periods of planned triennial maintenance turnarounds by the application of cash reserves, our quarterly cash distributions, if any, will generally not be stable and will vary from quarter to quarter and year to year as a direct result of variations in (i) our operating performance (ii) cash flow caused by fluctuations in the price of propane and propylene, working capital or capital expenditures and (iii) such other cash reserves deemed necessary and appropriate by the board of directors of our General Partner. Such variations may be significant. The board of directors of our General Partner may change the foregoing distribution policy at any time. Our partnership agreement does not require us to pay cash distributions to our unitholders on a quarterly or other basis.

        The board of directors of our General Partner has elected to establish a reserve for the purpose of funding the planned triennial plant turnarounds. The purpose of the reserve is to evenly spread over the period between turnarounds (i) the cost associated with the turnaround and (ii) all or a portion of the projected lost margin due to the purchase of propylene as inventory for sales to our customers during the turnaround. In the period preceding our 2013 turnaround, the board of directors of our General Partner reserved $77.0 million to fund (i) the capital costs associated with the change-out of our reactor catalyst described elsewhere in this annual report, (ii) other capital and maintenance projects completed as part of the turnaround and (iii) the lost margin due to the purchase of propylene as inventory for sales to our customers during the turnaround. This reserve was funded by withholding $5.9 million of available cash each quarter combined with amounts set aside by the pre-IPO investors at the time of the IPO. Our General Partner's board of directors currently intends to continue reserving $5.9 million of available cash each quarter to fund a reserve to cover similar costs with respect to future turnarounds.

        The board of directors of our General Partner may decide to establish additional reserves for other activities as needed. A decision by the board of directors of our General Partner to increase existing cash reserves or establish new reserves would have an adverse impact on the available cash in the quarter in which the reserves are withheld. Further, should a reserve prove inadequate to fund the underlying costs, cash distributions may be adversely impacted.

Limitations on Cash Distributions; Our Ability to Change Our Cash Distribution Policy

        There is no guarantee that unitholders will receive quarterly cash distributions from us. Our unitholders have no contractual or other legal right to receive cash distributions from us on a quarterly or other basis. The board of directors of our General Partner has adopted a policy pursuant to which we will distribute to our unitholders each quarter all of the available cash we generate each quarter as described above and as determined quarterly by the board of directors of our General Partner, but it may change this policy at any time. Our distribution policy is subject to certain restrictions, including:

Item 6.    Selected Financial Data

        This data should be read in conjunction with, and is qualified in its entirety by reference to, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Item 8. Financial Statements and Supplementary Data."

E-36


        The selected financial data under the caption Balance Sheet Data as of December 31, 2013 and 2012 and under the captions Statement of Operations Data and Cash Flow Data for each of the three years in the period ended December 31, 2013, have been derived from our audited consolidated financial statements included in Item 8. "Financial Statements and Supplementary Data." The selected financial data under the caption Balance Sheet Data as of December 31, 2011, 2010 and 2009 and under the captions Statement of Operations Data and Cash Flow Data for each of the two years in the periods ended December 31, 2010 and 2009, have been derived from our audited combined financial statements not included herein.

        The information presented in the selected financial data below contains the combined financial results of PL Propylene LLC, our predecessor for accounting purposes, as of and for all years presented through December 31, 2011. The consolidated financial results for the year ended December 31, 2012, also include the results of operations of the Partnership for the period beginning March 30, 2012, the date of the contribution of our predecessor's net assets to the Partnership. The consolidated balance sheet as of December 31, 2013 and 2012, and the consolidated financial results for the year ended December 31, 2013, present the consolidated financial position and consolidated results of operations of the Partnership.

        On May 9, 2012, we completed our IPO of 35,000,000 common units. A portion of our fiscal year 2012 results prior to our IPO are included in the total 2012 results presented herein. The Partnership has omitted net income per unit for all periods other than the periods ended December 31, 2013 and 2012, as the Partnership operated under a different capital structure prior to the closing of the IPO and, as a result, the per unit data prior to 2012 would not be meaningful to investors. Per unit data for 2012 is computed for the period from the closing of the IPO on May 9, 2012, through December 31, 2012.

        Adjusted EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors and commercial banks, to assess:

        Adjusted EBITDA should not be considered an alternative to net income, operating income, net cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA may have material limitations as a performance measure because it excludes some, but not all, items that affect net income from

E-37


operations. In addition, Adjusted EBITDA presented by other companies may not be comparable to our presentation, since each company may define this term differently.

Effective May 9, 2012, pursuant to an omnibus agreement (or the "omnibus agreement") with our General Partner, Propylene Holdings, PL Propylene and PL Manufacturing LLC (or "PL Manufacturing"), to the extent that we made payments for realized losses under our propane swaps, PL Manufacturing and the PL Manufacturing Members, through our General Partner, were responsible for making quarterly capital contributions to us in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. The amount of realized loss on derivatives shown as an adjustment for EBITDA represents the amount received from PL Manufacturing and the PL Manufacturing Members. During the period from January 1 through May 9, 2012, we made payments of approximately $26.0 million for realized hedge losses which were excluded from the amount of realized losses on derivatives in the reconciliation to Adjusted EBITDA. On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. See discussion of the omnibus agreement in Note 2 to our consolidated financial statements included elsewhere herein.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations.

        You should read the following discussion of the financial condition and results of operations for the Partnership in conjunction with the financial statements and notes thereto of PetroLogistics LP, which are included in this report in Item 8, and information set forth in Risk Factors under Item 1A.

Overview

        We currently own and operate the only U.S. propane dehydrogenation (or "PDH") facility (or "our facility") producing propylene from propane. Propylene is one of the basic building blocks for petrochemicals that is utilized in the production of a variety of end uses including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. We are the only independent, dedicated "on-purpose" propylene producer in North America. We are strategically located in the vicinity of the Houston Ship Channel, which is situated within the largest propylene consumption region in North America. We also have access to the leading global fractionation and storage hub for propane located at Mt. Belvieu, Texas. Our location provides us with excellent access and connectivity to both customers and feedstock suppliers. Our facility had an original nameplate capacity of 1.2 billion pounds of propylene annually. However, based on plant optimization and operating improvements, our facility currently has an annual production capacity of approximately 1.4 billion pounds. In 2013 we produced 1.1 billion pounds of propylene, due in part to the impact of our first triennial plant turnaround.

        We currently have multi-year contracts for the sale of our propylene with The Dow Chemical Company (or "Dow"), Total Petrochemicals USA, Inc. (or "Total"), BASF Corporation (or "BASF') and INEOS Olefins and Polymers USA (or "INEOS") that expire between 2016 and 2018 and a one-year contract with LyondellBasell Industries N.V. (or "LyondellBasell") that ends in December 2014. Our customer contracts provide for minimum and maximum offtake volumes, with the minimum customer-contracted volumes representing approximately 75% of our current facility capacity and the maximum reflecting approximately 96% of our current facility capacity. Each of our customer contracts contain pricing terms based upon market rates. In addition to our contracted sales, we have and will continue to make additional propylene sales on a spot basis. We also opportunistically purchase propylene on a spot basis to enable us to maintain adequate inventory.

        Propylene comprised 98% and 97% of our sales in 2013 and 2012, respectively. In addition to propylene, we also produce commercial quantities of hydrogen and C4 mix/C5+ streams, which do not represent a material part of our production.

        Our historical results of operations and cash flows may not be indicative of results of operations and cash flows to be expected in the future, principally for the following reasons:

E-40


E-41


Factors Affecting Results

        We believe key factors that influence our business and impact our operating results are (1) the propane-to-propylene spread, (2) our facility's capacity utilization, and (3) customer sales.

Propane-to-Propylene Spread

        The price spread between propane, our sole feedstock, and propylene, our primary product, largely determines our gross margin and is the key driver of our profitability.

        Propylene sales constitute substantially all of our sales. Propylene is a commodity, and its price can be cyclical and highly volatile. The price of propylene depends on a number of factors, including general economic conditions, cyclical trends in end-user markets and supply and demand balances. The customers under our propylene sales contracts (Dow, Total, BASF, INEOS and LyondellBasell) each pay market-based prices for propylene, and a significant decrease in propylene prices would have a

E-42


material adverse effect on revenue generated from these customers. In addition, a decrease in the price of propylene would result in decreased revenue from any sales of propylene on the spot market. Assuming sales of 1.3 billion pounds, a one cent increase (decrease) in the propane-to-propylene spread results in an increase (decrease) of $13 million in gross margin and approximately $0.09 per unit in distributable cash flow.

        Propane is the sole feedstock in our production process, and the cost of propane represents a substantial portion of our cost of sales. Enterprise supplies 100% of our required propane feedstock volume under a multi-year contract at market-based prices, which prices are subject to fluctuations in response to changes in supply, demand, market uncertainties and a variety of additional factors beyond our control. See "Item 7A Quantitative and Qualitative Disclosures about Market Risk."

        Our facility had an original nameplate capacity of 1.2 billion pounds of propylene annually. However, based on plant optimization and operating improvements, our facility currently has an annual production capacity of approximately 1.4 billion pounds. In 2013 we produced 1.1 billion pounds of propylene, due in part to the impact of our first triennial plant turnaround. Actual annual production will vary based on a number of factors, including the amount of downtime for planned and unplanned maintenance on the facility and overall efficiency of the facility. During 2013 our facility operated at an average capacity utilization rate of approximately 74%. Any significant planned or unplanned downtime may affect not only production, and therefore sales, but also capital expenditures and direct operating expenses, primarily maintenance expenses, and fuel and utilities.

Customer Sales

        Our results are affected by customer demand. When propylene production exceeds customer nominations, we build inventory for future sales or seek opportunities to sell the excess production on the spot market. When customer nominations exceed our propylene production and we elect not to declare force majeure, we satisfy the shortfall out of inventory or purchase propylene on the spot market. In certain circumstances, a customer will nominate more than it will actually take in a month. In those situations, we deliver the excess product into storage, defer the sales recognition until the customer takes actual delivery and recognize an exchange inventory balance with the customer. We invoice customers for quantities delivered to the customer and for quantities delivered into storage on the customer's behalf and are paid by the customer based on its actual monthly nominations. As a result of the foregoing, customer billings in one month may not result in sales until a future month.

        In addition to utilizing the key factors affecting our operating results described above to evaluate our performance, our management uses certain additional financial and operational measures as well. These measures include Adjusted EBITDA and health, safety and environmental performance.

        We define Adjusted EBITDA as net income (loss) plus interest expense, loss on early extinguishment of debt, income tax expense, depreciation, amortization and accretion, equity-based compensation expense, unrealized (gain) loss on derivatives and, effective May 9, 2012, through April 19, 2013, realized losses on the propane swaps. To the extent we made payments on the propane swaps, PL Manufacturing and the PL Manufacturing Members, through our General Partner, were, pursuant to the omnibus agreement, responsible for making quarterly capital contributions to us in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter resulting in a capital contribution to us and a

E-43


zero net effect on cash and partners' capital. Adjusted EBITDA is a non-U.S. GAAP financial measure that may be used by our management and by external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, to assess:

        We view Adjusted EBITDA as an important indicator of cash flow generation. Adjusted EBITDA is principally affected by our sales volumes, the propane-to-propylene spread, capacity utilization, propane-to-propylene conversion factors and, to a lesser extent, the prices of natural gas and our by-products. Other than the cost of propane and natural gas, production-related expenses generally remain stable across broad ranges of throughput volumes, but can fluctuate significantly depending on the planned and unplanned maintenance performed during a specific period. Our Adjusted EBITDA and available cash may not always correlate to each other.

        Adjusted EBITDA should not be considered an alternative to net income (loss), operating income (loss), cash flows from operating activities or any other measure of financial performance presented in accordance with U.S. GAAP. Our Adjusted EBITDA may not be comparable to Adjusted EBITDA or similarly titled measures of other entities, as other entities may not calculate Adjusted EBITDA in the same manner as we do. Our management compensates for the limitations of Adjusted EBITDA as an analytical tool by reviewing the comparable U.S. GAAP measures, understanding the differences between the measures and incorporating this knowledge into management's decision-making processes. Adjusted EBITDA should not be viewed as indicative of the actual amount we have available for distributions or that we plan to distribute for a given period.

Effective May 9, 2012, pursuant to the omnibus agreement, to the extent that we made payments for realized losses under our propane swaps, PL Manufacturing and the PL Manufacturing Members, through our General Partner, were responsible for making quarterly capital contributions to us in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. The amount of realized loss on derivatives shown as an adjustment for EBITDA represents the amount received from PL Manufacturing and the PL Manufacturing Members. During the period from January 1 through May 9, 2012, we made payments of approximately $26.0 million for realized hedge losses which were excluded from the amount of realized losses on derivatives in the reconciliation to Adjusted EBITDA. On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. See "Item 13. Certain Relationships and Related Transactions, and Director Independence—Transactions with Related Parties—Omnibus Agreement."

Health, Safety and Environmental Performance

        We consider our ability to manage our facility and customer needs in a safe and reliable manner to be a critical factor in assessing our performance. Accordingly, we have an extensive training program and set annual goals on achieving operating performance and safety measures that promote the reliable operation of our facility and a safe working environment for our employees. Further, we closely monitor all environmental metrics to assure compliance with all regulatory requirements and that we operate in an environmentally responsible manner.

        We have included the following descriptions of the components of our results of operations to assist in the review of the following discussion and analysis.

        Sales.    Sales are comprised of propylene sales and by-product sales, which include hydrogen and C4 mix/C5+ streams.

        Cost of Sales.    Cost of sales represents the costs of propylene and by-products sold. These costs include the cost of propane, fuel and utilities used in the propylene production process, as well as direct operating expenses and insurance and property tax expenses associated with our facility. Direct operating expenses include all direct and indirect labor at our facility, materials, supplies, and other

E-45


expenses associated with the operation and maintenance of the facility. Depreciation, amortization and accretion expenses, exclusive of amortization of deferred financing fees, as well as equity-based compensation expense for awards granted to operating personnel are also included within cost of sales. During periods in which our facility operates below normal capacity, we record charges to cost of sales to reflect unabsorbed fixed overhead costs.

        General and Administrative Expense.    General and administrative expense includes salary and benefits costs for executive management, accounting and information technology personnel, as well as legal, audit, tax and other professional service costs and charges for equity-based compensation expense. In 2011, a portion of these costs were billed to us by an affiliated company pursuant to a former services agreement. As of January 1, 2012, these services are provided by our General Partner. See "Item 13. Certain Relationships and Related Transactions and Director Independence."

        Development Expense.    Development expense includes preliminary engineering and design work for capital projects which do not qualify for capitalization.

        Management Fee.    Management fee consists of the expense incurred through our management services agreement with Lindsay Goldberg. This agreement terminated upon the completion of our IPO.

        (Gain) loss on Derivatives, net.    Our commodity derivative contracts were recorded as derivative assets and liabilities, as applicable, at fair value on the balance sheet. Our commodity derivative contracts did not qualify for hedge accounting treatment. Consequently, the associated unrealized gains and losses were recorded as current expense or income in the statement of comprehensive income (loss). Unrealized gains or losses on derivatives represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows until settlement occurs. For further discussion see "—Liquidity and Capital Resources."

        Interest Expense, Net.    Interest expense includes expense incurred on outstanding debt balances, loan commitment expenses and the amortization of deferred financing fees and discount under our credit facilities. Loan commitment expense is comprised of the fees assessed on the unutilized portion of our credit facility. Interest income results from earnings on available cash balances and is offset against interest expense.

        Income Tax Expense.    As an entity operating in the State of Texas, we are subject to the Texas Margin Tax. This tax represents a tax on gross margin, as adjusted, and is reported as income tax expense.

        Sales.    For the year ended December 31, 2013, sales increased $6.8 million which was driven by an increase in the average benchmark polymer grade propylene price from an average of 60.4 cents per pound for the year ended December 31, 2012, to an average of 68.7 cents per pound for the same period in 2013. This increase in price was partially offset by a decrease in the amount of propylene sold from 1,298 million pounds for the year ended December 31, 2012 to 1,149 million pounds in the comparable 2013 period, a decrease of 11%. The decrease in sales volume was a result of lower customer demand during 2013.

        Cost of sales was $513.2 million, or approximately 68% of sales for 2013 compared to $528.6 million, or approximately 70% of sales, for 2012. The primary component of cost of sales is the propane feedstock, which represented approximately 69% of total production costs for 2013 compared to 75% in 2012. This decrease is primarily due to a decrease in the volume of propylene we produced at our facility in 2013 compared to 2012. In 2013, we produced 1.07 billion pounds of propylene compared to 1.26 billion pounds of propylene produced in 2012. The majority of the production

E-47


decrease from 2012 to 2013 was due to our triennial planned major maintenance, or turnaround, performed in the fourth quarter of 2013. Although the price of propane fluctuated throughout 2013, the average propane price in both 2013 and 2012 was $1.00 per gallon. Fuel and utilities costs increased in 2013, due to higher natural gas prices when compared to 2012. Insurance and property taxes increased $1.7 million in 2013 as compared with 2012 due to increased insurance premiums and an increase in the assessed taxable value of the facility. Direct operating and other expenses increased $2.0 million in 2013 compared to 2012 due to an increase maintenance expense. During the turnaround while the facility was shutdown, we performed repairs and maintenance at the facility in addition to the planned major maintenance. During the year ended December 31, 2013, we purchased propylene at a cost of approximately $52.3 million in order to meet sales obligations to customers during our triennial turnaround. The change in product inventory represents the change in the value of the product inventory between the beginning and end of the period based on the weighted average cost of production.

        General and Administrative Expense.    General and administrative expense was $19.7 million for 2013, compared to $66.2 million for 2012, a decrease of $46.5 million. This decrease was due to a $53.2 million decrease in general and administrative related equity-based compensation expense from $55.7 million in 2012 to $2.5 million in 2013. Equity-based compensation expense in 2013 resulted from grants of unit-based awards in 2012 following our IPO. The expense is recognized over the service period during which the unit-based awards vest, which is generally three years for the employee awards and one year for awards to members of the General Partner's board of directors. Equity-based compensation expense in 2012 primarily resulted from equity-based awards granted in September 2010 to both our employees and certain employees of affiliated entities, who were treated for accounting purposes as non-employees. The equity-based awards outstanding at the time of the IPO became fully vested as of the completion of the IPO, and we recorded equity-based compensation expense of $54.8 million in general and administrative expense in connection with the pre-IPO awards. The decrease in equity-based compensation expense from 2012 to 2013 was offset by increased expense for audit, tax, and consulting services incurred for an entire year of being a public company in 2013 versus eight months in 2012, as well as costs associated with our initial implementation of Sarbanes-Oxley 404 internal controls documentation and procedures and the associated external audit of our internal controls over financial reporting. In addition, we incurred additional expense in 2013 for the implementation of a new accounting, project control and maintenance information system, as well as increased payroll and benefits costs.

        Development Expense.    We incurred expenses related to development costs for development projects as well as potential expansion and profit enhancement projects at our facility totaling $1.9 million and $11.6 million in 2013 and 2012, respectively.

        Management Fee.    We incurred management fees of $0.7 million in 2012. The management fees related to a management services agreement, pursuant to which we were to pay Lindsay Goldberg a total of $2.0 million per year beginning in 2011. This agreement terminated under its terms on the closing date of the IPO and, therefore, no expense was incurred during 2013.

        Loss (Gain) on Derivatives, net.    Commencing October 2011 and through March 2012, we entered into propane swaps with settlement dates in 2012 and 2013. These propane swaps were terminated in April 2013. We recorded the propane swaps at fair value using observable inputs based on market data obtained from independent sources. Because the propane swaps did not qualify for hedge accounting treatment, the mark-to market adjustments are reported in our statements of comprehensive income (loss). We incurred an unrealized gain of $63.1 million and a realized loss of $61.4 million associated with propane swaps during the year ended December 31, 2013, as all swap positions were terminated during the second quarter of 2013. The net loss on derivatives of $166.3 million for the year ended December 31, 2012, is comprised of mark-to market unrealized losses of $61.4 million and realized

E-48


losses of $104.9 million which were recognized at each monthly settlement date. Pursuant to the omnibus agreement, the realized losses on the propane swaps were borne by PL Manufacturing and the PL Manufacturing Members starting May 9, 2012 through the date of final settlement of the propane swaps.

        Interest Expense, Net.    Interest expense, net includes $23.1 million incurred on borrowings in 2013 on an average daily debt balance of $361.4 million and $21.8 million incurred on borrowings in 2012 on an average daily debt balance of $301.0 million. Also included in interest expense, net in 2013 and 2012 are $2.1 million and $2.5 million of deferred financing cost amortization and original issue discount amortization of $0.3 million and $0.9 million, respectively. The average interest rate for 2013 was 6.4% and the average interest rate during 2012 was 7%. Loan commitment expense, also a component of interest expense, net, was $0.8 million in 2013 compared to $1.0 million in 2012.

        Loss on Early Extinguishment of Debt.    We recognized a loss on early extinguishment of debt of $20.4 million and $7.0 million in 2013 and 2012, respectively, related to the termination and pay-off of our previous credit facilities. See discussion under "—Liquidity and Capital Resources."

        Income Tax Expense.    Income tax expense was $2.5 million for 2013, compared to $0.8 million for 2012, resulting from the income taxes on gross margin within the state of Texas.

        Sales.    For the year ended December 31, 2012, we produced 1,261 million pounds of propylene compared to 845 million pounds during 2011, which represents an increase in production of 49%. In 2011, we had not yet achieved production rates at or near current capacity. Accordingly, production was limited, and as a result sales were lower during 2011. This increase in production volume for 2012 was offset by a decrease in the average polymer grade contract benchmark propylene price. In 2012, the average polymer grade contract benchmark price was 60.4 cents per pound compared to an average of 75.5 cents per pound for the same period in 2011, a price drop of 15.1 cents per pound or 20%.

        Cost of sales was $528.6 million, or approximately 70% of sales, for 2012. The primary component of cost of sales is the propane feedstock, which represented approximately 75% of total production costs for 2012 compared to 73% in 2011. The increase in propane expense is primarily due to an increase in the volume of propylene we produced at our facility. This increase in propane usage was partially offset by a decrease in propane pricing from an average of $1.46 per gallon in 2011 to $1.00 per gallon in 2012. Fuel and utilities costs decreased in 2012, due to lower natural gas prices when compared to 2011. Insurance and property taxes increased $4.7 million in 2012 as compared with 2011 due to increased insurance premiums and an increase in the assessed taxable value of the facility. Direct operating and other expenses decreased $3.9 million in 2012 compared to 2011 primarily due to a reduction in maintenance expense as compared with maintenance expense incurred in 2011 during the startup phase of our facility. This decrease was offset by higher equity-based compensation expense in 2012 related to equity-based awards granted in September 2010. During the year ended December 31, 2012, we purchased propylene at a cost of approximately $16.9 million to meet customer obligations. The change in product inventory represents the change in the value of the product inventory between the beginning and end of the period based on the weighted average cost of production.

        General and Administrative Expense.    General and administrative expense was $66.2 million for 2012, compared to $73.4 million for 2011, a decrease of $7.2 million. This decrease was due to a decrease in equity-based compensation expense from $64.1 million in 2011 to $55.7 million in 2012. Equity-based compensation expense resulted from equity-based awards granted in September 2010 to both our employees and certain employees of affiliated entities, who are treated for accounting purposes as non-employees. For periods prior to January 1, 2012, the fair value of these equity-based awards was adjusted on a quarterly basis with the change in fair value reflected in our results of operations. The equity-based awards outstanding at the time of the IPO became fully vested as of the completion of the IPO, and we recorded equity-based compensation expense of $54.8 million in general and administrative expense in connection with the pre-IPO awards.

        Development Expense.    We incurred expenses related to development costs totaling $11.6 million in 2012 primarily for potential expansion and profit enhancement projects at our facility.

        Management Fee.    We incurred management fees of $0.7 million in 2012, compared to $2.0 million in 2011. The management fees relate to a management services agreement, pursuant to which we were to pay Lindsay Goldberg a total of $2.0 million per year beginning in 2011. This agreement terminated under its terms on the closing date of the IPO.

E-50


        Loss on Derivatives, net.    Commencing October 2011 and through March 2012, we entered into the propane swaps with settlement dates in 2012 and 2013. The net loss on derivatives of $1.7 million in 2011 represents the unrealized loss on derivatives through December 31, 2011. Because the propane swaps do not qualify for hedge accounting treatment, we adjust the carrying value of the propane swaps to fair market value using observable inputs based on market data obtained from independent sources. The fair market, or mark-to market, adjustments are reported in our statements of comprehensive income (loss). The net loss on derivatives of $166.3 million for the year ended December 31, 2012, is comprised of mark-to market unrealized losses of $61.4 million and realized losses of $104.9 million which are recognized at each monthly settlement date. Pursuant to the omnibus agreement, the realized losses on the propane swaps are borne by PL Manufacturing and the PL Manufacturing Members starting May 9, 2012.

        Interest Expense, Net.    Interest expense, net includes $21.8 million incurred on borrowings in 2012, on an average daily debt balance of $301.0 million. During 2011, the average daily debt balance was $166.7 million, resulting in interest charges of $13.3 million. Also included in interest expense, net in 2012 are $2.5 million of deferred financing cost amortization as well as original issue discount amortization of $0.9 million. During 2011, we recorded amortization of deferred financing costs of $3.1 million. The interest rate during 2012 was 7% after the completion of the refinancing of our credit facility, prior to the refinancing the rate remained unchanged at 8% during 2011. Loan commitment expense, also a component of interest expense, net, was $1.0 million in 2012 compared to $1.4 million in 2011.

        Loss on Early Extinguishment of Debt.    We recognized a loss on early extinguishment of debt of $7.0 million in 2012 related to the termination and pay-off of our prior credit facility. See discussion under "—Liquidity and Capital Resources."

        Income Tax Expense.    Income tax expense was $0.8 million for 2012, compared to $1.4 million for 2011, resulting from the income taxes on gross margin within the state of Texas.

        The preparation of our financial statements in accordance with GAAP requires that management make estimates and assumptions affecting the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting period. The following is a discussion of the accounting policies applied by us that are considered to involve a higher degree of judgment in their application. See Note 2 to our consolidated financial statements.

Deferred Major Maintenance Costs

        Plant turnarounds are periodically performed to help ensure the long-term reliability and safety of integrated plant machinery at our continuous process production facility. During the turnaround, the primary activity is the replacement of the reactor catalyst as well as other major maintenance activities, some of which extend the useful life of plant machinery or increase output and/or efficiency of the facility. Our plant turnarounds occur approximately every three years and require a multi-week shutdown of plant operations. Specific procedures performed during the turnaround include the disassembly, inspection and replacement or overhaul of plant machinery (pressure vessels, piping, heat exchangers, etc.) and rotating equipment (compressors, pumps, turbines, etc.), equipment recalibration and internal equipment efficiency assessments.

        Preceding a turnaround, facilities experience decreased efficiency in resource conversion to finished products. Replacement or overhaul of equipment and items such as compressors, turbines, pumps, motors, valves, piping and other parts that have an estimated useful life of at least three years, the

E-51


internal assessment of production equipment, replacement of aged catalysts, and new installation/recalibration of measurement and control devices result in increased production output and/or improved plant efficiency after the turnaround. Turnaround activities are betterments that meet at least one of the following criteria: 1) extend the equipment useful life, or 2) increase the output and/or efficiency of the equipment. As a result, we follow the deferral method of accounting for major maintenance costs; and thus, they are capitalized and amortized over the period benefited, which is generally the three-year period until the next turnaround. Deferred major maintenance costs are reported under Property, plant and equipment, net, in the consolidated balance sheet at December 31, 2013. We expense repair and maintenance activities in the period performed.

        We classify deferred major maintenance costs as an investing activity under the caption "Capital expenditures and deferred major maintenance costs" in the Statement of Cash Flows, since this cash outflow relates to expenditures related to long-lived productive assets. Repair, maintenance and related labor costs are expensed as incurred and are included in operating cash flows.

Impairment of Long-Lived Assets

        We account for the impairment of long-lived assets in accordance with Financial Accounting Standards Board (or "FASB") Accounting Standards Codification (or "ASC") Topic 360, "Plant, Property and Equipment—Impairment or Disposal of Long-Lived Assets." Long-lived assets used in operations are assessed for possible impairment when events or changes in circumstances indicate a potential significant deterioration in future cash flows projected to be generated by the assets. Individual assets are grouped for impairment purposes at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets—generally at the facility level, as we produce one primary product.

        If, upon review, the sum of the projected undiscounted cash flows is less than the carrying value of the asset group, the carrying value is written down to estimated fair value. The fair values of impaired assets are usually determined based on the present value of projected future cash flows using discount rates commensurate with the risks involved in the asset group, as quoted market prices in active markets are generally not available. The expected future cash flows used for impairment reviews and related fair value calculations are based on projected production volumes, sales volumes, prices, and costs, taking into consideration available internal and external information at the date of review.

        Should an impairment of assets arise, we may be required to record a charge to operations that could be material to the period reported. To date, we have not recorded any impairment charges.

        Beginning in October 2011 and through March 2012, we entered into commodity derivative contracts with settlement dates in 2012 and 2013 to manage our exposure to commodity price risk with respect to propane, our sole feedstock. Our principal use of commodity derivative contracts is to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our commodity derivative contracts act as a hedging (offset) mechanism against the volatility of energy commodity prices by allowing us to transfer this price risk to counterparties who are able and willing to bear it.

        FASB ASC Topic 815, "Derivatives and Hedging" ("ASC Topic 815"), addresses the accounting for derivative contracts. We entered into our commodity derivative contracts to economically hedge an exposure through a relationship that does not qualify for hedge accounting under ASC Topic 815. We recorded our derivative contracts as derivative assets and liabilities, as applicable, at fair value on the balance sheet, and the associated unrealized gains and losses as current expense or income in the statement of comprehensive income (loss). Unrealized gains or losses on derivatives represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash

E-52


flows on the cash flow statement. Until settlement occurred, this treatment resulted in non-cash gains or losses being reported in our operating results as gain or loss on derivatives. See Note 7 to our consolidated financial statements.

        Contemporaneous with the closing of our IPO, we entered into the omnibus agreement with our General Partner, Propylene Holdings and PL Manufacturing, and PL Manufacturing entered into a common unit pledge agreement (the "pledge agreement") with the PL Manufacturing Members, pursuant to which PL Manufacturing and the PL Manufacturing Members, through our General Partner, were allocated all of our benefits and obligations under the propane swaps. See "Item 13. Certain Relationships and Related Transactions, and Director Independence." Under the omnibus agreement and the pledge agreement, any amounts received by us under the propane swaps were distributed, through our General Partner, to PL Manufacturing and the PL Manufacturing Members, and any amounts that we were required to pay under the propane swaps were required to be contributed back to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

        On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. While the Partnership did not ultimately bear the cost of the propane swaps, it remained a party to the propane swaps, and was obligated to make payments to the propane swap counterparties as they come due and to post any collateral as required, under the terms of the propane swaps. With the termination of the propane swaps, we will no longer incur such gains or losses in future periods. For the year ended December 31, 2013, we generated a net gain on the propane swaps totaling $1.7 million. For the years ended December 31, 2012 and 2011, we incurred losses on the propane swaps totaling $166.3 million and $1.7 million, respectively. During 2013 and 2012, we recorded capital contributions from PL Manufacturing and the PL Manufacturing Members for reimbursement of realized losses on the propane swaps of $61.4 million and $78.9 million, respectively, for payments we made under the propane swaps. The reimbursement of the realized losses on the propane swaps are reflected as capital contributions in our Consolidated Statement of Changes in Partners' Capital. See Note 2 to our consolidated financial statements.

Equity-Based Compensation

        We recognize compensation expense related to equity-based awards granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. Non-employee directors acting in their role as members of a board of directors are treated as employees. The grant date fair value of equity-based awards to directors are recognized on a straight-line basis over the vesting period of the awards so long as the awards were given to the directors for their services as directors.

        We account for equity-based awards granted to non-employees based on the estimated fair value of the awards. The measurement of equity-based compensation for awards granted to non-employees is subject to periodic adjustment as the awards vest, and the resulting change in value is recognized in the statement of comprehensive income (loss) during the period the related services are rendered.

        For a further discussion of our historical equity-based compensation, please see Notes 13 and 14 to our consolidated financial statements included elsewhere in this annual report.

Liquidity and Capital Resources

        Our principal source of liquidity is cash flow from operations. Our principal uses of cash have been and are expected to be for working capital, distributions, capital expenditures and funding our debt service obligations. We believe that our cash from operations will be adequate to satisfy

E-53


commercial commitments for the next twelve months and that the borrowings under our revolving credit facility will be adequate to fund our planned capital expenditures and working capital needs. However, future capital expenditures and other cash requirements may be higher than we currently expect as a result of various factors.

        Our ability to make distributions, to make payments on and to refinance our indebtedness, to fund planned capital expenditures and to satisfy our other capital and commercial commitments will depend on our ability to generate cash flows in the future. This, to a certain extent, is subject to the prevailing propane-to-propylene spread, natural gas prices and general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. Our business may not generate sufficient cash flows from operations, and future borrowings may not be available to us under our credit facilities in amounts sufficient to enable us to make quarterly distributions, finance necessary capital expenditures, service our indebtedness or fund our other liquidity needs. We may seek to sell assets or issue debt securities or additional equity securities to fund our liquidity needs but may not be able to do so. We may also need to refinance all or a portion of our indebtedness on or before maturity. We may not be able to refinance any of our indebtedness on commercially reasonable terms or at all.

Initial Public Offering

        On May 4, 2012, our common units began trading on the NYSE under the symbol "PDH." On May 9, 2012, we completed our IPO of 35,000,000 common units representing limited partner interests. Pursuant to a Registration Statement on Form S-1, as amended through the date of its effectiveness, we sold 1,500,000 common units, and Propylene Holdings LLC sold 33,500,000 common units at a price to the public of $17.00 per common unit ($15.98 per common unit, net of underwriting discounts). Immediately prior to the IPO, the outstanding limited partner interests in the Partnership were recapitalized into 139,000,000 common units pursuant to an amended and restated limited partnership agreement. We received net proceeds of approximately $24.0 million from the sale of the common units, after deducting underwriting discounts. IPO costs totaled $5.5 million. We did not receive any proceeds from the sale of common units by Propylene Holdings.

Capital Spending

        During the year ended December 31, 2013, we incurred capital expenditures of $58.2 million primarily consisting of deferred major maintenance, replacement of the catalyst, maintenance capital expenditures, plant enhancement projects and equipment.

        During the year ended December 31, 2012, we incurred capital expenditures of $25.4 million primarily for plant enhancements, maintenance capital expenditures, catalyst in advance of our 2013 turnaround and equipment.

        During the year ended December 31, 2011, we incurred capital expenditures of $28.5 million primarily for plant modifications that were aimed at improving the operating efficiency of our facility.

        Our future capital spending will be determined by management and approved by the board of directors of our General Partner. We currently plan to incur capital expenditures of approximately $40.8 million during 2014. Included in this amount is approximately $10.0 million of maintenance capital expenditures and $30.8 million for profit enhancement projects.

        Our estimated capital expenditures and planned major maintenance costs are subject to change due to unforeseen circumstances and unanticipated increases in the cost, scope and completion time of each respective project. For example, we may experience increases in labor or equipment costs necessary to comply with government regulations or to complete projects that sustain or improve the profitability of our facility.

E-54


        Maintenance capital expenditures and future planned turnaround expenses will be funded using cash flow from operations. Other capital expenditures (including acquisitions and plant expansion capital expenditures), should we identify opportunities for such expenditures, may be funded using cash flow from operations or, if significant, will be funded by issuances of debt or equity. We have elected to reserve amounts in the period(s) preceding planned major maintenance projects in order to fund the estimated capital costs in the period in which the project(s) are expected to occur. The actual costs associated with planned major maintenance projects may, however, differ from the estimated amounts reserved. We completed our first triennial turnaround during 2013. Costs incurred in 2013 in connection with the turnaround were $41.1 million, which includes $15.5 million in deferred major maintenance and $14.7 million for the replacement of the reactor catalyst. During the turnaround, we also completed other capital projects totaling $4.6 million and incurred repair and maintenance expenses totaling $6.3 million. Through September 30, 2013, we reserved $5.9 million of available cash each quarter, which, together with amounts contributed by pre-IPO investors, totaled $77.0 million to fund: (i) capital costs associated with the change-out of the reactor catalyst, (ii) other capital and maintenance projects completed as part of the turnaround and (iii) all or a portion of the lost margin due to the purchase of inventory for sales to our customers during the turnaround. In 2012, we incurred $6.3 million related to the turnaround which included the initial payments for the replacement catalyst. We funded these costs from the aforementioned cash reserves.

        On March 28, 2013, we and our wholly-owned finance subsidiary, PetroLogistics Finance Corp., co-issued jointly and severally $365.0 million of senior unsecured notes due 2020 (the "senior notes"), and we entered into an amended and restated credit agreement which extended our revolving credit facility (together with the senior notes, the "2013 credit facilities") from $120 million to $170 million with Morgan Stanley Senior Funding, Inc. (the "Agent"), and the lender parties thereto. We used the net proceeds from the issuance of the senior notes, after underwriting fees of $7.3 million, to (1) repay all borrowings outstanding under our term loan facility in the amount of approximately $347.4 million, (2) pay approximately $6.9 million for the call premium and costs associated with the cancellation of our term loan facility and (3) pay $3.0 million in commitment fees and approximately $0.4 million in transaction fees. In addition, we paid approximately $1.3 million in third party transaction costs from cash on hand. The senior notes were issued at the par value of $365 million, and are reported as long-term debt in our consolidated balance sheet at December 31, 2013.

        The indenture governing the senior notes and our amended and restated credit agreement contain certain restrictive financial covenants including limitations on our ability to incur additional debt and the requirement under the terms of our revolver to maintain a total senior secured leverage ratio, as defined, no greater than 2.0 to 1.0, but as to the senior secured leverage ratio test only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2013, the aggregate amounts outstanding under the revolving credit facility exceeds $120 million. At December 31, 2013, there were no outstanding borrowings under the revolving credit facility.

        Interest Rate and Fees.    The senior notes bear interest at a fixed rate of 6.25% per annum, payable on April 1 and October 1 with the first payment due October 1, 2013. The revolving credit facility bears interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the revolving credit facility ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greatest of the prime rate in effect and the federal funds effective rate in effect plus 1/2 of 1.0%. The revolving credit facility also contains a facility commitment fee at a rate of 0.50% per annum based on the daily unused amount of the commitment amount of $170 million payable in arrears on the last day of March, June, September and December of each year.

E-55


        Amortization and Final Maturity.    The senior notes have a maturity date of April 1, 2020. Prior to April 1, 2016, we may redeem all or part of the senior notes at a redemption price equal to the sum of 100% of the principal amount of the senior notes, plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the date of redemption. We may also redeem some or all of the senior notes on or after April 1, 2016, at a premium (expressed as a percentage of principal) plus accrued and unpaid interest, if any, on the notes redeemed to the applicable redemption date. The revolving credit facility has a maturity date of March 28, 2018.

        Guarantees.    The senior notes rank equally in right of payment with all of our existing and future senior indebtedness. The notes are guaranteed on a senior unsecured basis by our wholly-owned subsidiary PL Propylene. The full and unconditional guarantee ranks equally with all of the existing and future senior indebtedness of our guarantor subsidiaries. PL Propylene and PetroLogistics Finance Corp. are our only subsidiaries. We have no independent assets or operations, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended. The senior notes and the guarantee are effectively subordinated to all of our and our guarantor subsidiaries' existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. In addition, the senior notes are structurally subordinated to all future indebtedness and other liabilities of any of our subsidiaries that are not issuers or guarantors of the senior notes.

        In connection with our refinancing, we wrote off approximately $20.4 million of unamortized deferred financing costs, unamortized issue discount, and retirement premium associated with the prior credit facility. The write-off of these costs is reflected as a loss on extinguishment of debt in our consolidated statement of comprehensive income (loss) for the year ended December 31, 2013. At December 31, 2013, we had $170.0 million available under the new revolving credit facility. PetroLogistics LP has no independent assets or operations. There are no significant restrictions on the ability of PetroLogistics LP or any guarantor to obtain funds from its consolidated subsidiaries.

        We entered into an interest rate protection agreement in July 2012 whereby we capped the three month LIBOR rate at 2.0% for up to $115.5 million on our term loan. The agreement terminates on March 27, 2014.

Cash Flows

Operating Activities

        Net cash provided by operating activities for the year ended December 31, 2013, was $191.0 million. This positive cash flow resulted primarily from net income of $175.0 million and a decrease in net working capital, excluding cash, of $15.8 million. This net decrease in working capital was mainly due to the return of $40.0 million cash held as collateral by the propane swaps counterparty following the termination of the propane swaps offset by an increase in accounts receivable of $21.7 million from December 31, 2012 to December 31, 2013. Non-cash charges totaling $63.2 million were offset by unrealized gains on derivatives totaling $63.1 million.

        Net cash provided by operating activities for the year ended December 31, 2012, was $121.0 million. Although we had a net loss of $56.7 million for the year ended December 31, 2012, our results reflect certain non-cash charges for equity-based compensation, depreciation, amortization and accretion, amortization of deferred financing costs and discount, loss on early extinguishment of debt and deferred income taxes totaling $101.5 million. We also had non-cash unrealized losses on the propane swaps of $61.4 million. We also had cash flows from operations due to a change in working capital. The change in working capital is partially due to our posting of $40.0 million as cash collateral for the propane swaps, which is reported as a current asset in our consolidated balance sheet. The change in working capital was also due to our restricted cash decreasing by $34.9 million from 2011.

E-56


Restrictions on our cash balances were lifted in 2012 in connection with the refinancing of our prior credit facility making the cash available for working capital.

        Net cash provided by operating activities for the year ended December 31, 2011, was $84.6 million. This positive cash flow from operating activities was primarily attributable to net income of $21.9 million plus non-cash charges totaling $107.5 million, which include equity-based compensation expense, depreciation, amortization and accretion expense as well as amortization of deferred financing costs, unrealized loss on derivatives and deferred income tax expense, reduced by an increase in restricted cash of $28.0 million and an increase in working capital of $16.8 million. The increase in restricted cash included the establishment of a major maintenance reserve of $3.0 million as required by our prior credit facility.

Investing Activities

        Net cash used in investing activities for the year ended December 31, 2013, was $58.2 million, resulting from capital expenditures for our facility of $42.7 million and deferred major maintenance costs of $15.5 million pertaining to our 2013 turnaround.

        Net cash used in investing activities for the year ended December 31, 2012, was $37.6 million, resulting from capital expenditures for our facility of $25.4 million and the purchase of additional emissions credits for $9.3 million and additional licensing fees of $2.9 million for the licensed technology used in our propylene production process due to our increased capacity.

        Net cash used in investing activities for the year ended December 31, 2011, was $28.5 million as a result of capital expenditures for our facility.

        Net cash used in financing activities for the year ended December 31, 2013, was $138.9 million. Our cash flows used in financing activities were primarily due to cash distributions to unitholders totaling $237.7 million, including DERs on LTIP units. The distributions were net of $61.4 million from PL Manufacturing and the PL Manufacturing Members for reimbursement of 2013 realized losses on the propane swaps and $31.8 million from PL Manufacturing and the PL Manufacturing Members in 2013 for reimbursement of fourth quarter 2012 realized losses on the propane swaps. Proceeds from borrowings, net of repayments, including the issuance of our senior notes and term loan refinancing, totaled $6.8 million, and we incurred $1.2 million in deferred financing costs related to the issuance of our senior notes and refinancing of our term loan.

        Net cash used in financing activities for the year ended December 31, 2012, was $52.0 million. Our cash flows used in financing activities were primarily due to the full repayment of $145.1 million on our former debt facility, distributions to our sponsors totaling $250.0 million and cash distributions to unitholders of $65.6 million. Cash distributions to unitholders were reduced by the reimbursement of $47.0 million for realized losses on the propane swaps by PL Manufacturing and the PL Manufacturing Members. We also received $343.0 million in proceeds from our term debt in 2012. Concurrent with our debt refinancing, we were able to release a debt service reserve of $10.9 million that had been set aside under the terms of the former credit facility. During the period from the date of the refinancing to December 31, 2012, we borrowed and repaid $42.7 million under our revolving credit facility and repaid principal of $2.6 million on our term loan facility. We also received proceeds of approximately $24.0 million from the IPO. Additionally, we incurred deferred financing costs of $13.5 million related to the refinancing of our debt and the IPO.

        Net cash used in financing activities for the year ended December 31, 2011 was $56.1 million. Our negative cash flows from financing activities were primarily due to the net repayment of $44.4 million on our prior revolving credit facility and term loan during the year ended December 31, 2011 as well as

E-57


the establishment of a debt service reserve of $10.9 million as required by our prior credit agreement. We also incurred $3.2 million in deferred financing costs primarily related to our IPO, and we received member contributions of $2.3 million during the year ended December 31, 2011.

Off-Balance Sheet Arrangements

        We do not have any "off-balance sheet arrangements" as such term is defined within the rules and regulations of the SEC.

Item 7A    Quantitative and Qualitative Disclosures About Market Risk

        Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in financial and commodity market prices and rates. Given that our business is currently based entirely in the U.S., we are not directly exposed to foreign currency exchange rate risk.

Commodity Price Risk

        Propylene sales constitute substantially all of our sales. Propylene is a commodity, and its price can be cyclical and highly volatile. The price of propylene depends on a number of factors, including general economic conditions, cyclical trends in end-user markets and supply and demand balances. The

E-58


customers under our propylene sales contracts (Dow, Total, BASF, INEOS and LyondellBasell) each pay market-based prices for propylene, and a significant decrease in propylene prices would have a material adverse effect on revenue generated from these customers.

        Propane is the sole feedstock in our production process, and the cost of propane represents a substantial portion of our cost of sales. The price of propane is correlated to the price of crude oil and is influenced by the price of natural gas. The prices for crude oil and natural gas are cyclical and volatile, and as a result, the price of propane can be cyclical and volatile. The propane export market may also impact the price of propane. According to the U.S. Energy Information Administration, propane exports increased significantly during 2013.

        If propane costs increase, the market price of propylene may not rise correspondingly or at all. Timing differences between propane prices, which may change daily, and the market price of propylene, which is set monthly, may narrow the propane-to-propylene spread and thus reduce our cash flow, which reduction could be material. Assuming sales of 1.3 billion pounds, a one cent increase (decrease) in the propane-to-propylene spread results in an increase (decrease) of $13 million in gross margin and approximately $0.09 per unit in distributable cash flow. We obtain all of the propane we need from a single supplier through its propane pipeline system, which is connected to the natural gas liquids and refined products storage hub at Mt. Belvieu. The price that we pay our supplier for propane fluctuates based on market prices. Propane prices could significantly increase in the future. In addition, following the expiration of our current propane supply contract, the price of storage and transportation of propane to our site is subject to change and could adversely impact our financial results.

        The raw materials we consume, such as natural gas, electricity and nitrogen, are generally commodity products that are readily available at market prices. We generally enter into supply agreements with particular suppliers, but disruptions of existing supply arrangements could substantially impact our profitability. If certain of our suppliers are unable to meet their obligations under present supply agreements, we may be forced to pay higher prices to obtain the necessary materials from other sources. In addition, if any of the raw materials that we use become unavailable within the geographic area from which they are now sourced, then we may not be able to obtain suitable or cost effective substitutes. Any interruption in the supply of raw materials will increase our costs or decrease our sales, which will reduce our cash flow.

        An increase in the price of natural gas could narrow the propane-to-propylene spread in two ways, each adversely affecting our gross margins. First, a significant increase in natural gas prices could be accompanied by an increase in the price of NGLs such as ethane. An increase in ethane prices could cause ethylene producers to favor the use of naphtha as a feedstock. Because the use of naphtha as a feedstock in the ethylene production process results in significantly more propylene as co-product than ethane, the result would be an increase in propylene production by ethylene plants. The increased supply of propylene would in turn exert downward pressure on the price of propylene, adversely affecting the price we obtain for the propylene we produce, both in the spot market and pursuant to our customer contracts, which are market-based.

        Second, an increase in the price of natural gas may be accompanied by an increase in the price of propane, as the majority of propane is derived from natural gas production, thereby further narrowing the propane-to-propylene spread and reducing our gross margins.

        Our supply agreements typically provide for market-based pricing and provide us no protection against price volatility. If the costs of any of our feedstock or raw materials rise, the market price of propylene may not rise correspondingly or at all. Timing differences between our feedstock or raw material prices, which may change daily, and the market price of propylene, which is set monthly, may have a negative effect on our cash flow. Any cost increase could have a material adverse effect on our business, results of operations, financial condition and liquidity.

E-59


        Commencing October 2011 through March 2012, we entered into propane swaps with the intent of reducing volatility in our cash flows due to fluctuations in the price of propane, our sole feedstock. Under the terms of the propane swaps, for a portion of our propane consumption, we locked in the price of propane as a fixed percentage of the price of Brent crude oil (the "contractual percentage"). Beginning in January 2012, and at the conclusion of each subsequent month through the May 2013 cancellation date, we performed a calculation to determine the average actual price of propane for that month as a percentage of the average actual price of Brent crude oil for that month (the "actual percentage"). If the actual percentage exceeded the contractual percentage under the propane swaps, we were owed a sum by the propane swaps counterparty. If the contractual percentage exceeded the actual percentage under the propane swaps, we owed a sum to the propane swaps counterparty.

        Upon the closing of the IPO, we entered into the omnibus agreement and the pledge agreement, pursuant to which PL Manufacturing and the PL Manufacturing Members, through our General Partner, assumed all of our benefits and obligations under the propane swaps. Under the omnibus agreement and the pledge agreement, any amounts received by us under the propane swaps were to be distributed, through our General Partner, to the PL Manufacturing Members, and any amounts that we were required to pay under the propane swaps were contributed back to us as a capital contribution by the PL Manufacturing Members. On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. During the year ended December 31, 2013, we recorded capital contributions from PL Manufacturing and the PL Manufacturing Members of $61.4 million for reimbursement of realized losses incurred on the propane swaps which were funded through reductions in the distributions we paid to PL Manufacturing and the PL Manufacturing Members on the common units they own.

        In the future, management may elect to use derivative commodity instruments consistent with our overall business objectives to avoid unnecessary risk and to limit, to the extent practical, risks associated with certain of our operating activities.

        Our senior notes bear interest at a fixed interest rate while our revolving credit facility has a variable interest rate based on an underlying base rate plus an applicable margin. The applicable margin ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greatest of the prime rate in effect and the federal funds effective rate in effect plus 1/2 of 1%. At December 31, 2013, we had no outstanding borrowings under our revolving credit facility.

        Our management will continue to monitor whether financial derivatives become available which could effectively hedge identified risks. In the future, management may elect to use derivative financial instruments consistent with our overall business objectives to avoid unnecessary risk and to limit, to the extent practical, risks associated with our operating activities.

Item 8.    Financial Statements and Supplementary Data.

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our Executive Chairman, our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on

E-60


the Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2013.

        The effectiveness of our internal control over financial reporting as of December 31, 2013, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their audit report which appears herein.

Report of Independent Registered Public Accounting Firm

The Board of Directors of PetroLogistics GP
General Partner of PetroLogistics LP
and the Common Unitholders of PetroLogistics LP

        We have audited the accompanying consolidated balance sheets of PetroLogistics LP as of December 31, 2013 and 2012, and the related consolidated statements of comprehensive income (loss), changes in partners' capital, and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of PetroLogistics LP at December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), PetroLogistics LP's internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated March 7, 2014 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors of PetroLogistics GP
General Partner of PetroLogistics LP
and the Common Unitholders of PetroLogistics LP

        We have audited PetroLogistics LP's internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). PetroLogistics LP's management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the partnership's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, PetroLogistics LP maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria .

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of PetroLogistics LP as of December 31, 2013 and 2012, and the related consolidated statements of comprehensive income (loss), changes in partners' capital, and cash flows for each of the three years in the period ended December 31, 2013 of PetroLogistics LP and our report dated March 7, 2014 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Nature of Operations

        As used in this report, the terms "PetroLogistics LP," "the Partnership," "we," "our," "us" or like terms, refer to PetroLogistics LP. The information presented herein contains the audited combined financial results of PL Propylene LLC (PL Propylene), our predecessor for accounting purposes (the "predecessor"), for all periods presented through March 30, 2012, the date of the contribution of the predecessor's net assets to the Partnership. The consolidated financial results for the year ended December 31, 2012, also include the results of operations of the Partnership for the period beginning March 30, 2012. The consolidated balance sheets as of December 31, 2013 and 2012, and the consolidated financial results for the year ended December 31, 2013, present solely the consolidated financial position and results of operations of the Partnership. References to "PL Manufacturing" refer to PL Manufacturing LLC, and references to the "PL Manufacturing Members" refer to the owners of 100% of the issued and outstanding equity interests in PL Manufacturing. References to our "General Partner" refer to PetroLogistics GP LLC. References to our "Sponsors" refer to Lindsay Goldberg LLC ("Lindsay Goldberg") and York Capital Management ("York") which collectively and indirectly own 84% of PetroLogistics GP (or "General Partner") and own approximately 63% of our common units.

        PetroLogistics LP is a Delaware limited partnership that was formed on June 9, 2011, by Propylene Holdings LLC ("Propylene Holdings") to own PL Propylene, a wholly-owned subsidiary of Propylene Holdings. On March 30, 2012, Propylene Holdings contributed PL Propylene to PetroLogistics LP. Because this transaction was a transaction between entities under common control, the contributed assets and liabilities of PL Propylene were recorded in the consolidated financial statements at PL Propylene's historical cost. Prior to the contribution, PetroLogistics LP had no operations and nominal assets and liabilities. On March 12, 2013, we formed a wholly-owned finance subsidiary, PetroLogistics Finance Corp. (or "Finance Corp."), for the sole purpose of being a co-issuer of a portion of the Partnership's indebtedness, including the senior unsecured notes discussed in Note 11. The General Partner holds a non-economic interest in the Partnership.

Nature of Operations

        We own and operate the only U.S. propane dehydrogenation facility (or "the facility") producing polymer grade and chemical grade propylene from propane. Propylene is used as one of the basic building blocks for petrochemicals in a variety of end uses, including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. In addition to propylene, the facility generates commercial quantities of the following by-products during the production process: hydrogen, C4 mix stream, and C5+ stream.

2. Significant Accounting Policies

        The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and include the accounts of the Partnership and its wholly-owned subsidiaries. All inter-company transactions and balances have been eliminated upon consolidation.

E-68



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

        The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting period. We review our estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates, and actual results could differ materially from those estimates.

        Sales of propylene and by-products are recorded when persuasive evidence of an arrangement exists, goods have been delivered, consideration to be received is fixed and determinable, and collectability is reasonably assured. Cash received in advance of product delivery to the customer is reported as deferred revenue. Upon delivery to the customer and satisfaction of the aforementioned criteria for sales recognition, the deferred revenue is reported as a sale. Sales are presented net of discounts and allowances. By-product sales are reported together with propylene sales. Transportation costs billed to customers are also recorded as a component of sales.

        Inventory purchases and sales transactions with the same counterparty are combined for accounting purposes if they were entered into in contemplation of each other. Inventory purchases and sales under buy/sell transactions are treated as inventory exchanges in our statements of comprehensive income (loss). This treatment of buy/sell transactions eliminates sales and purchases in equal amounts in our statements of comprehensive income (loss). Accordingly, no gain or loss is recognized on the transaction at the time, with any difference in value between the two transactions recorded as an additional cost of inventory.

Cost of Sales

        Cost of sales represents the costs of propylene and by-products sold. These costs include the cost of propane, fuel and utilities used in the propylene production process, such as natural gas, nitrogen and electricity, as well as direct operating expenses along with insurance and property tax expenses associated with the facility. Direct operating expenses include all direct and indirect labor at the facility as well as fixed and variable overhead expenses. Depreciation, amortization and accretion expenses, exclusive of the amortization of deferred financing fees, are also included within cost of sales.

        During certain periods in 2013, 2012 and 2011, the facility operated below normal capacity. Accordingly, we recorded charges to cost of sales to reflect unabsorbed fixed overhead costs.

Development Expense

        Development expense includes preliminary engineering and design work and other expenses for projects which do not qualify for capitalization under GAAP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

        We consider all short-term instruments with an original maturity of three months or less to be cash equivalents. We maintain cash in bank deposit accounts that, at times, may exceed federally insured limits. We have not experienced any losses in such accounts, and we believe we are not exposed to any significant credit risk on cash and cash equivalents.

Restricted Cash

        During 2011, following the conversion of our construction loan to a term loan that was scheduled to mature in 2014, we funded $10.9 million into a debt service reserve to serve as collateral for our debt. This cash outflow is classified as a financing cash flow in the 2011 consolidated statement of cash flows. Also during 2011, we funded $3.0 million into a major maintenance reserve, which was to be used to fund future major maintenance expenditures. This amount has been included in operating activities in the 2011 consolidated statement of cash flows. In connection with the refinancing of our construction loan into a term loan in 2012 (see Note 11), restrictions on our cash balances were lifted. The decrease in the debt service reserve of $10.9 million is classified as a financing cash flow, and the remaining restricted cash of $34.9 million is classified as an operating cash flow in the 2012 consolidated statement of cash flows.

Accounts Receivable

        We extend credit to customers in accordance with normal industry standards and terms. We review accounts receivable monthly and establish an allowance for doubtful accounts based on known factors surrounding the credit risk of specific customers, historical trends and other information. Accounts receivable are not collateralized, and we may charge interest on receivables should they become past due. No allowance for doubtful accounts was considered necessary at December 31, 2013 and 2012, and we have not recorded any interest income related to past due receivables.

        Inventory is carried at the lower of cost or market, with cost determined using the weighted-average method.

        As of December 31, 2013, prepaid expenses and other current assets consists primarily of $2.5 million for premiums paid for insurance which are amortized over the policy periods. As of December 31, 2012, prepaid expenses and other current assets consists primarily of a $40.0 million cash deposit we made to a counterparty as collateral for our commodity derivative contracts (the "propane swaps"). The cash was held by the counterparty and returned to us in 2013 following the termination of the propane swaps.

        Commencing October 2011 and through March 2012, we entered into commodity derivative contracts with settlement dates in 2012 and 2013 to manage our exposure to commodity price risk with respect to propane, our sole feedstock. The propane swaps were designed to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our propane swaps

E-70



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

were intended to act as a hedging (offset) mechanism against the volatility of energy commodity prices by allowing us to transfer some of the price risk to counterparties who were able and willing to bear it.

        Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC" or "Codification") Topic 815, Derivatives and Hedging ("ASC Topic 815"), addresses the accounting for derivative contracts. We entered into our commodity derivative contracts to economically hedge an exposure through a relationship that does not qualify for hedge accounting under ASC Topic 815. Our derivative contracts are recorded as derivative assets and liabilities, as applicable, at fair value on the balance sheet, and the associated unrealized gains and losses are recorded as current expense or income in the statement of comprehensive income (loss). Unrealized gains or losses on commodity derivative contracts represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows on the statement of cash flows. Until settlement occurred, this change in fair value resulted in non-cash gains or losses being reported in our operating results as gain or loss on derivatives.

        In addition to the propane swaps, we entered into an interest rate protection agreement in July 2012 for a nominal amount whereby we capped the three month LIBOR rate at 2.0% for up to $115.5 million on our term loan. The agreement terminates March 27, 2014.

Omnibus Agreement

        On May 9, 2012, we, the General Partner, Propylene Holdings, PL Propylene and PL Manufacturing LLC, entered into an omnibus agreement (the "omnibus agreement"). Pursuant to the omnibus agreement and a related pledge agreement (the "pledge agreement"), we allocated all of our benefits and obligations under the propane swaps to PL Manufacturing and the PL Manufacturing Members.

        On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

        While we did not bear any of the costs nor receive any of the benefits of the propane swaps upon entering the omnibus agreement, we remained a party to the propane swaps, and were obligated to make payments to the propane swap counterparties as they come due and to post any collateral as required, under the terms of the propane swap agreement. As a result, we continued to record the fair value of the propane swaps on our balance sheet with the related gains or losses reflected in our statement of comprehensive income (loss). To the extent that the Partnership made payments under the propane swaps, PL Manufacturing and the PL Manufacturing Members were responsible for making quarterly capital contributions in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. During the years ended December 31, 2013 and 2012, PL Manufacturing and the PL Manufacturing Members paid approximately $93.2 million and $47.0 million, respectively, to us as reimbursement for realized losses on the propane swaps with the 2012 period pro-rated from May 9, 2012, the closing date of our initial public offering (the "IPO"), through December 31, 2012. See Note 3 regarding the IPO.

        In connection with the termination of the propane swaps, we paid a cancellation payment of $34.4 million in May 2013, of which $5.4 million was reimbursed through a reduction in the distribution

E-71

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

paid to PL Manufacturing and the PL Manufacturing Members in May 2013 in accordance with the terms of the omnibus agreement. The remaining $29.0 million was settled with cash held as collateral by the propane swap counterparty and was immediately reimbursed by PL Manufacturing and the PL Manufacturing Members. During the years ended December 31, 2013 and 2012, we recorded capital contributions of approximately $61.4 million and $78.9 million, respectively, for the reimbursement of the realized losses on the propane swaps and the reimbursement of the termination payment by PL Manufacturing and the PL Manufacturing Members. We received the final reimbursement for realized losses from PL Manufacturing and the PL Manufacturing Members on August 14, 2013, at which time the omnibus agreement terminated in accordance with its terms.

Property, Plant, and Equipment

        Property, plant and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Upon retirement or sale, we remove the cost of the asset and the related accumulated depreciation and reflect any resulting gain or loss in the statements of comprehensive income (loss).

        Repair and maintenance expenditures incurred in order to maintain the day-to-day operation of our existing assets are charged to expense as incurred. Costs associated with acquisitions and improvements that expand existing capacity or extend useful life, including related interest costs, are capitalized.

        Planned major maintenance projects, also referred to as turnarounds, are periodically performed to help ensure the long-term reliability and safety of integrated plant machinery at our continuous process production facility. During the planned major maintenance project the primary activity is the replacement of the reactor catalyst as well as other major maintenance activities, some of which extend the useful life of plant machinery or increase output and/or efficiency of the facility. Our planned major maintenance project occurs approximately every three years and requires a multi-week shutdown of plant operations. Specific procedures performed during the turnaround include the disassembly, inspection and replacement or overhaul of plant machinery (pressure vessels, piping, heat exchangers, etc.) and rotating equipment (compressors, pumps, turbines, etc.), equipment recalibration and internal equipment efficiency assessments.

        Preceding a turnaround, facilities experience decreased efficiency in resource conversion to finished products. Replacement or overhaul of equipment and items such as compressors, turbines, pumps, motors, valves, piping and other parts that have an estimated useful life of at least three years, the internal assessment of production equipment, replacement of aged catalysts, and new installation/recalibration of measurement and control devices result in increased production output and/or improved plant efficiency after the turnaround. Turnaround activities are betterments that meet at least one of the following criteria: 1) extend the equipment useful life, or 2) increase the output and/or efficiency of the equipment. As a result, we follow the deferral method of accounting for major maintenance costs; and thus, they are capitalized and amortized over the period benefited, which is generally the three-year period until the next turnaround. Deferred major maintenance costs are reported under Property, plant and equipment, net, in the consolidated balance sheet at December 31, 2013. We expense repair and maintenance activities in the period performed.

2. Significant Accounting Policies (Continued)

Intangible Assets

        Intangible assets include the technology license we acquired related to the propane dehydrogenation process, which is essential to the design, construction and operation of the facility, as well as emission credits. The technology license is being amortized on a straight-line basis over its estimated useful life of 25 years. The emission credits are an indefinite life intangible which is subject to an annual evaluation for impairment.

        Deferred financing costs and other assets as of December 31, 2013 and 2012, consist primarily of deferred financing costs incurred in connection with the closings of our credit facilities in March 2013 and March 2012, respectively. The costs associated with our credit facilities are being amortized using the effective interest method and are classified as interest expense. During 2013 we completed the refinancing of our term loan, and the remaining unamortized costs associated with the term loan were written off at that time resulting in a loss on early extinguishment of debt of $20.4 million. During 2012 we successfully completed the refinancing of our construction loan into a term loan, and the remaining unamortized costs associated with the construction loan were written off at that time resulting in a loss on early extinguishment of debt totaling $7.0 million.

        Long-lived assets used in operations are assessed for possible impairment when events or changes in circumstances indicate a potential significant deterioration in future cash flows projected to be generated by the assets. Individual assets are grouped for impairment purposes at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which is generally at the facility level, as we produce one principal product.

        If, upon review, the sum of the projected undiscounted cash flows is less than the carrying value of the asset group, the carrying value is written down to the estimated fair value. The fair values of impaired assets are usually determined based on the present value of projected future cash flows using discount rates commensurate with the risks involved in the asset group, as quoted market prices in active markets are generally not available. The expected future cash flows used for impairment reviews and related fair value calculations are based on projected production volumes, sales volumes, prices and costs, taking into consideration available internal and external information at the date of review.

        Should an impairment of assets arise, we would be required to record a charge to operations that could be material to the period reported. We have not recorded any impairment charges in any period.

        An asset and a liability are recorded at fair value when there is a legal obligation associated with the retirement of a long-lived asset and the amount can be reasonably estimated. When the liability is initially recorded, this cost is capitalized by increasing the carrying amount of the related long-lived asset. Over time, the liability is increased for changes in present value, and the capitalized cost is depreciated over the estimated useful life of the related asset.

        Where we can reasonably estimate the asset retirement obligation, we accrue a liability based on an estimate of the timing and amount of settlement. In estimating our asset retirement obligations, we

E-73



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

utilize several assumptions based on when the liabilities were recorded, including an inflation rate and a credit-adjusted discount rate. We record changes in these estimates based on changes in the expected amount and timing of payments to settle our obligations.

        Environmental expenditures are expensed or capitalized as appropriate, depending on future economic benefit. Expenditures that relate to an existing condition caused by past operations and that do not have future economic benefit are expensed. Liabilities for expenditures are recorded on an undiscounted basis unless the amount and timing of cash payments for the liability are fixed or determinable, in which case they are recorded on a discounted basis. Expenditures that create future benefits or contribute to future revenue generation are capitalized.

Income Taxes

        We are a partnership and are treated as a partnership for federal tax purposes whereby the impact of our operations is subject to tax at the partner level. Therefore, no federal income taxes are recognized in the consolidated financial statements. The aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined because information regarding each partner's tax attributes is not available to us.

        As an entity operating in the State of Texas, we are subject to the Texas Margin Tax, which is an income tax. We follow the liability method of accounting for these income taxes. Deferred income tax assets and liabilities are recognized for temporary differences between the assets and liabilities for financial reporting and tax purposes.

        We recognize the tax effects of any uncertain tax positions we may adopt if the position taken by us is more likely than not sustainable based on its technical merits. If a tax position meets such criteria, the tax effect that would be recognized by us would be the largest amount of benefit with more than a 50% chance of being realized. See Note 12 for additional information regarding our income taxes.

Equity-Based Compensation

        We recognize compensation expense related to equity-based awards granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures (see Notes 13 and 14). The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.

        We also account for equity-based awards granted to non-employees based on the estimated fair value of the awards. The measurement of equity-based compensation for awards granted to non-employees is subject to periodic adjustment as the awards vest, and the resulting change in value is recognized in the statement of comprehensive income (loss) during the period the related services are rendered.

        We consider cash and cash equivalents, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable-related parties, and accrued liabilities to be financial instruments in which the carrying amounts represent fair value because of the short-term nature of the accounts.

        Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated or generally unobservable inputs. The Codification establishes a hierarchical disclosure framework that ranks the quality and reliability of information used to determine fair values. The hierarchy is associated with the level of pricing observability utilized in measuring fair value and defines three levels of inputs to the fair value measurement process—quoted prices are the most reliable valuation inputs, whereas model values that include inputs based on unobservable data are the least reliable. Each fair value measurement must be assigned to a level corresponding to the lowest level input that is significant to the fair value measurement in its entirety.

        Assets and liabilities that are carried at fair value are classified and disclosed in one of the following three categories:

Level 1—Quoted market prices in active markets for identical assets and liabilities.

Level 2—Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3—Unobservable inputs that are not corroborated by market data.

        The Partnership makes certain assumptions it believes that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. Credit risk of the Partnership and its counterparties is incorporated in the valuation of assets and liabilities. The Partnership believes it uses valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

        The following table presents the financial instruments that require fair value disclosure as of December 31, 2013, by level within the hierarchy:

        The senior notes and variable rate debt are deemed to be Level 2 financial instruments because they are based on observable market data. At December 31, 2013 and 2012, the fair values were determined based on active trades and market corroborated data.

        The valuation assumptions utilized to measure the fair value of our propane swaps were observable inputs based on market data obtained from independent sources and are considered Level 2 inputs. To determine the fair value of the propane swaps, we utilized quoted prices for similar assets, liabilities and market-corroborated inputs. See Note 7 for discussion regarding our propane swaps.

        There are no financial instruments that are split across the levels, and there have been no financial instruments that transferred between the levels during the years ended December 31, 2013 and 2012.

Segment Reporting

        We operate in one segment for the production and sale of propylene and related by-products. All of our operations are located in Houston, Texas.

        Net income (loss) per common unit for a given period is based on the distributions that are made to the unitholders plus an allocation of undistributed net income (loss) based on provisions of the partnership agreement, divided by the weighted average number of common units outstanding. The two-class method dictates that net income (loss) for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income (loss) be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income (loss) as if all of the net income (loss) for the period had been distributed in accordance with the partnership agreement. Unit-based awards granted under the PetroLogistics Long-Term Incentive Plan (the "Long-Term Incentive Plan") are eligible for Distribution Equivalent Rights ("DERs"). To the extent that non-forfeitable DERs are awarded, the underlying nonvested unit-based awards are considered participating securities for purposes of determining net income (loss) per unit. Undistributed income (loss) is allocated to participating securities based on the proportional relationship of the weighted average number of common units and unit-based awards outstanding. Undistributed losses (including those resulting from distributions in excess of net income) are allocated to common units based on provisions of the partnership agreement. Undistributed losses are not allocated to nonvested unit-based awards as they do not participate in net losses. Distributions declared

and paid in the period are treated as distributed earnings in the computation of earnings per common unit even though cash distributions are not necessarily derived from current or prior period earnings.

        The General Partner does not have an economic interest in the Partnership and, therefore, does not participate in the Partnership's net income (loss). Prior to the IPO, our predecessor was wholly-owned by Propylene Holdings. Accordingly, net income (loss) per common unit is not presented for periods prior to the IPO.

Recently Issued Accounting Standards

        During the first quarter of 2013, we adopted Accounting Standards Update ("ASU") ASU 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities , which requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting agreement and ASU 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Asset and Liabilities , which clarifies the scope of the offsetting disclosures of ASU 2011-11. The objective of the disclosure requirement is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. The adoption of this standard did not have a material impact on our consolidated financial statements.

        In February 2013, the FASB issued authoritative guidance through ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income , surrounding the presentation of items reclassified from accumulated other comprehensive income (loss) to net income. This guidance requires entities to disclose, either in the notes to the consolidated financial statements or parenthetically on the face of the statement that reports comprehensive income (loss), items reclassified out of accumulated other comprehensive income (loss) and into net earnings in their entirety and the effect of the reclassification on each affected statement of operations line item. In addition, for accumulated other comprehensive income (loss) reclassification items that are not reclassified in their entirety into net earnings, a cross reference to other required accounting standard disclosures is required. We adopted this guidance in the first quarter of 2013. The adoption of this guidance did not have an impact on our statement of comprehensive income (loss) or on our disclosures as we have historically had no other comprehensive income (loss) items.

        Certain amounts for prior periods have been reclassified in order to conform to the current period presentation.

3. Initial Public Offering

        On May 3, 2012, in connection with the completion of the IPO, our General Partner amended and restated our partnership agreement and executed the First Amended and Restated Agreement of Limited Partnership of PetroLogistics LP (the "partnership agreement"), which governs the rights of our partners. Among others, revisions included the recapitalization of our limited partner interests into common units in connection with the IPO and provisions regarding allocations and distributions.

        On May 9, 2012, we completed our IPO. Our common units are traded on the NYSE under the symbol "PDH." We received net proceeds of approximately $24.0 million from the sale of the common units, after deducting underwriting discounts.

Amortization expense on the licensed technology for each of the next five years is estimated to be $0.6 million per year. We evaluated these emission credits for impairment at December 31, 2013, and concluded no impairment in their value had occurred.

7. Derivative Instruments

        Our business activities expose us to risks associated with unfavorable changes in the market price of propylene and propane. Commencing October 2011 through March 2012, we entered into certain derivative transactions (or "the propane swaps") with the intent of reducing volatility in our cash flows due to fluctuations in the price of propane, our sole feedstock. Under the terms of the arrangement, for a portion of our propane consumption, we locked in the price of propane as a fixed percentage of the price of Brent crude oil (the "contractual percentage"). Beginning in January 2012, and at the conclusion of each month thereafter through the May 2013 cancellation date, we performed a calculation to determine the average actual price of propane for that month as a percentage of the average actual price of Brent crude oil for that month (the "actual percentage"). If the actual percentage exceeded the contractual percentage under the propane swaps, we were owed a sum by the propane swaps counterparty. If the contractual percentage exceeded the actual percentage under the propane swaps, we owed a sum to the propane swaps counterparty. In March 2012, to offset the negative impact of the liability position of our propane swaps, we entered into reverse positions for a portion of our propane swaps maturing in the second half of 2013. These reverse positions resulted in an asset and are reflected as derivative assets in our consolidated balance sheet at December 31, 2012.

        On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members. See Note 2 regarding the omnibus agreement.

        As of December 31, 2013, we do not have any outstanding commodity forward contracts to hedge our forecasted energy commodity purchases.

        On March 28, 2013, we and our wholly owned finance subsidiary, PetroLogistics Finance Corp., co-issued jointly and severally $365.0 million of senior unsecured notes due 2020 (the "senior notes"), and we amended and extended our revolving credit facility from $120 million to $170 million with Morgan Stanley Senior Funding, Inc. (the "Agent"), and the lender parties thereto. We used the net proceeds from the issuance of the senior notes, after underwriting fees of $7.3 million, to (1) repay all borrowings outstanding under our term loan facility in the amount of $347.4 million, (2) pay $6.9 million for the call premium and costs associated with the cancellation of our term loan facility and (3) pay $3.0 million in commitment fees on our revolver and approximately $0.4 million in transaction fees. The proceeds from the senior notes, the repayment of the term loan and the transaction fees were net settled with the Agent as presented in the consolidated statement of cash flows for the year ended December 31, 2013. In addition, we incurred approximately $1.3 million in third party transaction costs. The senior notes were issued at the par value of $365 million, and are reported as long-term debt in our consolidated balance sheet at December 31, 2013. The refinancing of the term debt with the senior notes was treated as a debt extinguishment for accounting purposes, and we recorded total deferred financing costs of approximately $8.4 million. As part of our debt extinguishment, we wrote off unamortized deferred financing costs totaling $7.7 million and unamortized original issue discount of $5.8 million. The amendment and extension of our revolving

credit facility was treated as a debt modification for accounting purposes. We recorded total deferred financing costs associated with the revolving credit facility of approximately $3.6 million, and wrote off $0.1 million of deferred financing costs associated with the prior revolving credit facility. Cash paid for deferred financing costs totaled approximately $1.2 million with the remaining portion of $10.7 million net settled with the Agent through the senior note proceeds. The deferred financing costs associated with our senior notes and our credit facility are being amortized using the effective interest method over the terms of the underlying credit facilities.

        The indenture governing the senior notes and our amended and restated credit agreement contain certain restrictive financial covenants including limitations on our ability to incur additional debt and the requirement under the terms of our revolver to maintain a total senior secured leverage ratio, as defined, no greater than 2.0 to 1.0, but only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2013, the aggregate amounts outstanding under the revolving credit facility exceeds $120 million.

        Interest Rate and Fees.    The senior notes bear interest at a fixed rate of 6.25% per annum, payable on April 1 and October 1. The revolving credit facility bears interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the revolving credit facility ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greatest of the prime rate in effect and the federal funds effective rate in effect plus 1/2 of 1.0%. The revolving credit facility also contains a facility commitment fee at a rate of 0.50% per annum based on the daily unused amount of the commitment amount of $170 million payable in arrears on the last day of March, June, September and December of each year.

        Amortization and Final Maturity.    The senior notes have a maturity date of April 1, 2020. Prior to April 1, 2016, we may redeem all or part of the senior notes at a redemption price equal to the sum of 100% of the principal amount of the senior notes, plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the date of redemption. We may also redeem some or all of the senior notes on or after April 1, 2016, at the redemption prices (expressed as percentages of principal) set forth below, plus accrued and unpaid interest, if any, on the notes redeemed to the applicable redemption date.

        Guarantees.    The senior notes rank equally in right of payment with all of our existing and future senior indebtedness. The notes are guaranteed on a senior unsecured basis by our wholly-owned subsidiary PL Propylene. The full and unconditional guarantee ranks equally with all of the existing and future senior indebtedness of our guarantor subsidiaries. PL Propylene and PetroLogistics Finance Corp. are our only subsidiaries. Finance Corp. has no material assets and does not conduct any

operations. The Partnership has no independent assets or operations, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended. The senior notes and the guarantee are effectively subordinated to all of our and our guarantor subsidiaries' existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. In addition, the senior notes are structurally subordinated to all future indebtedness and other liabilities of any of our subsidiaries that are not issuers or guarantors of the senior notes.

2012 Credit Facilities

        On March 27, 2012, PL Propylene, entered into a term loan facility of $350.0 million and a revolving credit facility of $120.0 million with Morgan Stanley Senior Funding, Inc., and the lenders party thereto (together, the "2012 credit facilities"). We drew $350.0 million under the term loan facility and used (1) $60.8 million to refinance and cancel our prior credit facilities, (2) $250.0 million to reimburse our Sponsors for construction capital expenditures and (3) approximately $16.5 million to pay associated financing costs and debt discounts. PL Propylene used the remaining amount (approximately $22.7 million) for working capital. The term loan included a discount of $7.0 million, which is reported net, less related amortization, against the total outstanding debt in our consolidated balance sheet at December 31, 2012. The discount was being amortized over the term of the term loan using the effective interest method.

        The 2012 credit facilities contained certain restrictive financial covenants including limitations on our ability to incur additional debt and the requirement on our revolver to maintain a total secured leverage ratio, as defined, no greater than 4.0 to 1.0, but only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2012, the aggregate amounts outstanding under the revolving credit facility exceeded $100.0 million.

        Interest Rate and Fees.    Borrowings under the 2012 credit facilities carried interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the term loan facility and the revolving credit facility ranged from 4.75% for loans bearing interest at the Alternate Base Rate to 5.75% for loans bearing interest at LIBOR. During the first quarter of 2013, the interest rate on the term loan was based on LIBOR, subject to the LIBOR floor of 1.25%, resulting in a rate of 7%.

        The revolving credit facility also included a commitment fee calculated at a rate per annum equal to 0.50% on the average daily unused portion of the commitments under the revolving credit facility. In addition, we paid an annual management fee for the term loan facility and the revolving credit facility.

        Amortization and Final Maturity.    The term loan facility was being amortized in aggregate amounts of 0.25% per fiscal quarter of the original principal amount and had a final maturity date on the fifth anniversary of the closing date, March 27, 2017. The revolving credit facility maturity date was September 27, 2016.

        As required by our term loan facility, we entered into an interest rate protection agreement in July 2012 whereby we capped the three month LIBOR rate at 2.0% for up to $115.5 million on our term loan. The agreement remains in effect exclusive of the 2013 debt refinancing described below. The agreement terminates on March 27, 2014.

Loss on Extinguishment of Debt

        When we entered into the 2013 credit facilities, we recognized a loss on extinguishment of debt of approximately $20.4 million in our consolidated statement of comprehensive income (loss) for the year ended December 31, 2013. This loss on extinguishment resulted from the write off of approximately $7.7 million of unamortized deferred financing costs associated with the 2012 credit facilities. We also wrote off the unamortized original issue discount associated with the 2012 credit facilities in the amount of approximately $5.8 million. In addition, we paid a call premium of approximately $6.9 million for the prepayment of the term loan.

        When we entered into the 2012 debt refinancing, we wrote off approximately $7.0 million of unamortized deferred financing costs associated with the prior credit facility. The write-off of these costs is reflected as a loss on extinguishment of debt in our consolidated statement of comprehensive income (loss) for the year ended December 31, 2012.

Deferred tax liabilities at December 31, 2013 and 2012, primarily relate to excess depreciation related to the facility for tax purposes in the amounts of $1.5 million and $1.1 million, respectively. The deferred tax liability at December 31, 2012, is offset by a deferred tax asset related to the unrealized loss on the propane swaps in the amount of $0.6 million. As of December 31, 2013, our tax returns for 2009 through 2013 were open for examination by the State of Texas.

13. Employee Benefit Plans

Long-Term Incentive Plan

        The Long-Term Incentive Plan was adopted by our General Partner in May 2012. The Long-Term Incentive Plan is intended to promote our interests by providing incentive compensation, based on our common units, to employees, consultants, and directors and to encourage superior performance. The Long-Term Incentive Plan provides for grants of restricted units, phantom units, unit awards and other unit-based awards up to a plan maximum of 5,882,352 common units.

        If an award is cancelled, forfeited, exercised, settled in cash or otherwise terminates or expires without the actual delivery of units, the units subject to such award will again be available for awards under the Long-Term Incentive Plan; however, common units withheld to satisfy exercise prices or tax withholding obligations are not available for delivery pursuant to other awards. The common units delivered pursuant to awards under the Long-Term Incentive Plan may be common units acquired on the open market or acquired from the Partnership, any affiliate or any other person or any combination thereof, as determined in the discretion of the Long-Term Incentive Plan's administrative committee.

        A unit-based award under the Long-Term Incentive Plan is a phantom unit whose terms and conditions are set by the Long-Term Incentive Plan administrative committee and that generally vests over a period of time and during that time is subject to forfeiture. Our unit-based awards to employees will generally vest over a three-year period either annually from the date of grant or upon the third anniversary of the grant date provided the recipient has continuously provided services to us, our General Partner, or any other of our affiliates. Unit awards to members of our General Partner's board of directors vest upon the first anniversary of the date of grant.

        Certain unit-based awards are eligible for DERs. Absent any restrictions on the DERs in an award agreement, we will pay DERs to the holder of the award without restriction at approximately the same time as we pay quarterly cash distributions to our common unitholders.

        During the year ended December 31, 2013, we recognized total equity-based compensation expense of approximately $4.5 million related to the unit-based awards ($2.0 million as cost of sales and $2.5 million as general and administrative expense). The weighted average grant date fair value of unit-based awards is based on the closing price of our underlying common units on the grant date.

        During the year ended December 31, 2012, we recognized total equity-based compensation expense of approximately $2.2 million related to the unit-based awards ($1.3 million as cost of sales and $0.9 million as general and administrative expense). The weighted average grant date fair value of unit-based awards is based on the closing price of our underlying common units on the grant date.

At December 31, 2012, none of the unit-based awards were vested.

        Our General Partner sponsors the PetroLogistics GP, LLC Profit Sharing 401(k) Plan (or the "Profit Sharing Plan") on behalf of its employees. The General Partner makes a safe harbor matching contribution equal to 100% of employee salary deferrals up to 6% of an employee's compensation subject to Internal Revenue Service annual limitations. During the years ended December 31, 2013, 2012 and 2011, we made safe harbor matching contributions, through our General Partner, of $0.7 million, $0.5 million and $0.5 million, respectively. In addition to the matching contributions, we make discretionary profit sharing contributions which are allocated based on an employee's age on December 31. For the years ended December 31, 2013, 2012 and 2011, we made profit sharing contributions, through our General Partner, totaling $1.3 million, $1.0 million and $0.8 million, respectively. Employees are generally eligible to participate in the Profit Sharing Plan following one year of service and vest in the matching and profit sharing contributions at a rate of 20% per year following two years of employment.

14. PL Manufacturing Profits Interest Plan

        Prior to the IPO, PL Manufacturing maintained a profits interest plan (the "Profits Interest Plan") for the benefit of our employees, as well as the key management employees of certain affiliated companies. Because the Profits Interest Plan was intended to compensate award recipients with respect to the services they performed for our benefit, the equity-based compensation expense is reflected in our financial statements. The Profits Interests Units (comprising the Class B, C and D Units) as referenced in this footnote are fully vested units in PL Manufacturing. Profits Interests Units are not

the same security as our common units. Neither the Partnership nor the General Partner has any reimbursement obligation or other financial responsibility with respect to any future distributions made by PL Manufacturing.

        PetroLogistics Company LLC ("PetroLogistics LLC") is an affiliate entity. Through December 31, 2011, the senior executives who oversee our operations were employed by PetroLogistics LLC and provided management services to us pursuant to our services agreement with PetroLogistics LLC. The majority of the profits interests (or "Profits Interest Units") that PL Manufacturing issued were to persons employed by PetroLogistics LLC. For accounting purposes, we treated these awards as being made to non-employees through December 31, 2011. As of January 1, 2012, all PetroLogistics Company LLC employees transferred their employment to the General Partner and continued to provide management services to us. As of that date, the underlying grant date fair value of nonvested Profits Interest Units held by the former PetroLogistics LLC employees became fixed due to the change in employment status, and equity-based compensation expense attributed to these Profits Interest Units for the period from January 1, 2012 through the closing of the IPO in May 2012, was based on the underlying fair value of the Profits Interest Units as of January 1, 2012.

        Under the Profits Interest Plan, Class B, C and D Profits Interest Units were granted to management and employees. The Class B Profits Interest Units were fully vested at the date of issuance, July 23, 2008. The issued and outstanding Class C and Class D Profits Interest Units vested over four years beginning on the later of March 11, 2009, or the recipient's date of employment. The Class C and Class D Profits Interest Units became fully vested upon the closing of the IPO in May 2012. There were no forfeitures for any of the periods presented. At the closing of the IPO, remaining unrecognized compensation expense related to the previously nonvested Profits Interest Units was fully recognized in the amount of approximately $43.7 million.

        Equity-based compensation expense for all Profits Interest Units issued to employees was based on the estimated grant-date fair value of the Profits Interest Units less estimated forfeitures. We recognized this equity-based compensation expense on a straight-line basis over the requisite service period of the award. For Profits Interest Units granted to non-employees, non-vested Profits Interest Units were revalued at each reporting date at the current fair value, with any change in value reflected in the statements of comprehensive income (loss).

Estimates and Key Assumptions

        Our predecessor engaged an independent valuation specialist to assist us in determining the fair value of the Profits Interest Units for the years ended December 31, 2011 and 2010. The fair values of the Profits Interest Units as of December 31, 2011, were used as the basis for recording equity-based compensation expense related to the Profits Interest Units in 2012 as the values of the Profits Interest Units became fixed on January 1, 2012, due to the change in employment status of the former PetroLogistics LLC employees. Through March 31, 2011, we estimated the fair values of the Profits Interest Units using the Black-Scholes option-pricing model (or "OPM"). Beginning in the second quarter of 2011, we estimated the fair values of the Profits Interest Units using a hybrid method

E-89



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

14. PL Manufacturing Profits Interest Plan (Continued)

considering a probability weighting between (i) a 15% weighting with respect to a delayed exit scenario, in which we estimated the fair value of the Profits Interest Units using the OPM, and (ii) an 85% weighting with respect to an expected initial public offering scenario in which we effect an initial public offering as a master limited partnership, and which is largely based on comparable company valuations. These estimates required the use of highly subjective and complex assumptions to determine the fair value of equity-based awards, including the equity value of our business and the Profits Interests Units' expected time to liquidity, volatility, risk-free interest rate and dividend yield.

        Given the absence of a public trading market for the Profits Interest Units and in accordance with the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation , we exercised reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of the equity value of our business, including, among others: comparable company valuations, forecasts of future propylene and propane prices that are published by industry sources as of each valuation date; contemporaneous and retrospective valuations performed by an independent valuation specialist; the status of the facility's construction and operations, including risks attendant thereto; the likelihood of our achieving a liquidity event given prevailing market conditions; the nature, history and strategy for our business; the illiquidity of share-based awards involving private company securities; and current and future expectations about macroeconomic conditions.

        In valuing our business for purposes of the initial public offering scenario, we estimated the equity value of our business by considering forecasted sales and costs, including consideration of forecasts of future propylene and propane prices that were published by industry sources as of each valuation date. The forecasted financial results, including distributable cash flows, were then used to estimate the equity value of our business by applying yields of master limited partnerships. These market yields were based on then-current and expected distributions and unit prices of comparable master limited partnerships.

        In valuing our business prior to March 31, 2011, and for purposes of the delayed exit scenario on later dates, we estimated the equity value of our business by considering a weighted combination of value indications under two valuation approaches, an income approach and a market approach. The income approach estimated the present value of future estimated cash flows, based upon forecasted sales and costs, including consideration of forecasts of future propylene and propane prices that were published by industry sources as of each valuation date. These future cash flows were discounted to their present values using a discount rate derived from an analysis of the cost of capital of comparable publicly traded companies in our industry or similar lines of business as of each valuation date, as adjusted to reflect the risks inherent in our cash flows. The market approach estimates the fair value of a company by applying market multiples of comparable publicly traded companies in our industry or similar lines of business. These market multiples were based on key metrics implied by the enterprise values or acquisition values of comparable publicly traded companies.

        The fair values of our Profits Interest Units on a per-Unit basis were $3.16, $2.39 and $2.34 for Class B, Class C and Class D, respectively, at December 31, 2011. The weighted-average assumptions used in determining the fair values at December 31, 2011, included a 2-year estimated time to liquidity, 50% expected volatility, a 0.25% risk-free interest rate, and a 0% dividend yield.

        We estimated the time to a liquidity event based on our then-current expectations regarding the period during which we believed we could achieve significant milestones in our business strategy and

effect a liquidity event. We had no historical volatility with respect to the Profits Interest Units since the Profits Interest Units had never been publicly traded. Accordingly, the volatility was estimated by using volatility information from a peer group of publicly traded companies. The risk-free rate was based on the U.S. Treasury rate for notes with terms best matching the Profits Interest Units' expected terms. The dividend yield assumption of 0% was based on our history and our expectation of not paying dividends if we did not change our structure.

        At the date of the IPO, the per unit fair values of the Class B, Class C and Class D Profits Interest Units based on the waterfall allocation of the IPO proceeds to PL Manufacturing and the PL Manufacturing Members was $4.53, $3.73 and $3.73, respectively.

15. Related Party and Affiliate Transactions

        In November 2013 we entered into a Reimbursement Agreement with Lindsay Goldberg pursuant to which Lindsay Goldberg agreed to reimburse us for 50% of certain costs we incurred under a development agreement with a third party. In December 2013, Lindsay Goldberg reimbursed us $0.7 million of project development costs which we recorded as a reduction in development expense in our consolidated statements of comprehensive income (loss) for the year ended December 31, 2013. We ultimately elected not to pursue the potential development opportunity and anticipate receiving no further payments under the terms of the Reimbursement Agreement.

Services Agreement with PetroLogistics GP LLC

        We entered into a services agreement with our General Partner on January 1, 2012, pursuant to which our General Partner provides certain operational, managerial and general administrative services to us. All employees of PL Propylene and PetroLogistics LLC became employees of our General Partner on January 1, 2012. We reimburse the General Partner for all direct and indirect expenses the General Partner incurs or payments the General Partner makes on our behalf including, without limitation, salary, bonus, incentive cash compensation and employee benefits. During the years ended December 31, 2013 and 2012, we incurred fees of $21.9 million and $16.6 million, respectively, under the services agreement with our General Partner. The amounts we pay the General Partner for these services are reported in the statements of comprehensive income (loss) in the line item to which the expense relates.

        PL Midstream LLC ("PL Midstream"), a company in which we previously had a related party affiliation through Lindsay Goldberg, provided pipeline management services to us for a monthly charge. Lindsay Goldberg sold PL Midstream effective October 1, 2012. During the years ended December 31, 2012 and 2011, we incurred fees of $0.9 million and $0.8 million, respectively, for pipeline management services with PL Midstream which are included in cost of sales.

        During 2011 PetroLogistics LLC provided certain services to us, including: (i) accounting, payroll, and other financial services; (ii) information systems, network, and communication services; and (iii) management services. These services were provided in exchange for a monthly charge. During the year ended December 31, 2011, we incurred fees of $2.8 million from PetroLogistics LLC. These fees are reported as general and administrative expense. As of January 1, 2012, PetroLogistics LLC no longer provides general and administrative services to us, and these services are now being provided to us by our General Partner.

        The partnership agreement provides that each of our directors and officers may receive indemnification for actions associated with being a director or officer in order to enhance the indemnification rights provided under Delaware law and the partnership agreement. The partnership agreement provides each such director or officer with rights to receive his or her costs of defense if the individual is a party or witness to any proceeding other than a proceeding brought by or in the right of, us, provided that such director or officer has not acted in bad faith or engaged in fraud with respect to the action that gave rise to his or her participation in the proceeding.

Other

        We received the final reimbursement for realized losses from PL Manufacturing and the PL Manufacturing Members on August 14, 2013, at which time the omnibus agreement terminated in accordance with its terms. See Note 2 for further discussion relating to the omnibus agreement.

15. Related Party and Affiliate Transactions (Continued)

        During the years ended December 31, 2013, 2012 and 2011, we utilized the services of a company owned by Lindsay Goldberg in the amounts of approximately $2.9 million, $1.5 million, and $2.8 million, respectively, in connection with facility maintenance and construction activities.

        In 2011, we entered into an agreement with Lindsay Goldberg, under which we were to pay an annual fee of $2.0 million for advisory services. This agreement terminated under its terms with the IPO. At the closing of the IPO, we owed Lindsay Goldberg approximately $2.7 million related to this fee. This amount was waived by Lindsay Goldberg in May 2012 in connection with the IPO, and recorded as a contribution to partners' capital.

16. Concentration of Risk

        All of our revenues are derived from companies in the petrochemical industry, and our principal market is the Texas Gulf Coast region. This concentration could affect our overall exposure to credit risk since these customers may be affected by similar economic or other conditions. Generally, we do not require collateral for our accounts receivable; however, we attempt to negotiate prepayment agreements with customers that are deemed to be credit risks in order to minimize our potential exposure to any defaults.

        The following table presents the concentration of total sales to our largest customers:

 
  Year Ended
December 31,
 
 
  2013   2012   2011  

Dow Chemical Company (Dow)

    44 %   42 %   55 %

Total Petrochemicals USA, Inc. (Total)

    21 %   20 %   24 %

INEOS Olefins and Polymers USA (INEOS)

    18 %   18 %   16 %

LyondellBasell Industries N.V. (LyondellBasell)

    6 %   12 %    

Others (less than 10% individually)

    11 %   8 %   5 %
               

Total sales

    100 %   100 %   100 %
               
               

        We have entered into market-based sales contracts with our propylene customers to provide minimum annual quantities. (see Note 17). These minimum quantities comprise the substantial majority of the facility's anticipated annual production of propylene. This concentration in the volume of business transacted with a limited number of customers subjects us to substantial risks. The loss of any of the above-named customers without replacement on comparable terms could adversely affect our business, results of operations and financial condition. If we were to lose one or more of our current customers, we would seek to engage in sales transactions with other petrochemical companies on either a long-term contract basis or in the spot market, although there is no assurance we would be able to do so.

        We have entered into long-term market-based contracts for the purchase of propane, our sole feedstock, as well as nitrogen and natural gas, and each of these contracts has a sole supplier.

E-96



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

16. Concentration of Risk (Continued)

Interruptions in or limitations on volumes provided under these contracts subject us to the risk that we would be unable to meet our production requirements if we are unable to locate and procure replacement volumes from alternate sources.

        Our business activities expose us to the risk associated with changes in the market price of propylene and propane. In order to manage our exposure to the price risk related to propane, we began entering into the propane swaps in October 2011 through March 2012. Pursuant to the omnibus agreement, through our General Partner, we allocated all of our benefits and obligations under the propane swaps to PL Manufacturing and the PL Manufacturing Members. (see Note 7).

        In those situations where we are exposed to credit risk in our derivative instruments transactions, we analyze the counterparty's financial condition prior to entering into an agreement. Generally, we do not require collateral nor do we anticipate nonperformance by our counterparty.

17. Commitments and Contingencies

        We are obligated under long-term market-based propylene sales agreements to supply our customers with minimum quantities of propylene annually absent the occurrence of a force majeure event.

        The following table illustrates certain information regarding our propylene contracts as of December 31, 2013 (in millions of pounds):

Purchase Obligations

        Under the terms of our propylene storage and transportation contracts and a nitrogen supply contract, we are obligated to make payments that approximate the following: $1.1 million in 2014, $0.6 million in each of 2015, 2016 and 2017, $0.7 million in 2018 and $1.4 million thereafter. Our propylene storage and transportation contracts are based on the number of pounds of propylene stored with the counterparty and contain minimum annual storage and transportation amounts. During the years ended December 31, 2013, 2012, and 2011, we incurred $2.7 million, $2.5 million, and $1.7 million, respectively, under our long-term propylene storage and transportation contracts. Our nitrogen supply contract is a market-based contract that is adjusted annually for inflation and contains minimum quarterly purchase quantities. During the years ended December 31, 2013, 2012 and 2011, we incurred $1.0 million, $0.9 million, and $0.9 million, under our nitrogen supply contract. We also have

E-97



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

17. Commitments and Contingencies (Continued)

contracts to purchase propane and other materials used in the production process, but these contracts do not specify minimum purchase commitments.

        We are obligated for rentals under a lease for office space that commenced on April 1, 2012. Under this contract, we are obligated to make payments that approximate the following: $0.4 million in each of 2014, 2015, 2016, 2017, and $0.1 million in 2018. The office space lease expires April 30, 2018. During 2011, we did not have any non-cancelable lease agreements that extended beyond one year.

        For 2013, 2012, and 2011, we recorded total rent expense, which includes equipment rentals, of $1.8 million, $2.5 million, and $2.6 million, respectively.

        We are subject to extensive federal, state and local laws, regulations, rules and ordinances relating to pollution, protection of the environment and human health, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste materials. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or prohibitions on facility operations, substantial civil or criminal sanctions, as well as, under some environmental laws, the assessment of strict liability and/or joint and several liability. We are also subject to climate change laws and regulations. The facility may experience releases of hydrocarbons or other contaminants into the environment, or we may discover past releases that were previously unidentified. Although we maintain an inspection program designed to prevent and, as applicable, detect and address such releases promptly, damages and liabilities incurred due to any such environmental releases from our assets may affect our business. To date, management has not identified any material environmental obligations.

        The facility may experience damage as a result of an accident, natural disaster or terrorist activity. These hazards can cause personal injury and loss of life, severe damage to and destruction of property and equipment, pollution or environmental damage, and suspension of operations. We maintain insurance of various types that we consider adequate to cover our assets and operations. The insurance policies are subject to deductibles, limits and sub-limits and other terms, such that our ability to receive indemnification thereunder is limited. Our insurance does not cover every potential risk associated with operating the facility.

        The occurrence of a significant event that is not fully insured, indemnified or reserved against, or the failure of a party to meet its indemnification obligations, could materially and adversely affect our operations and financial condition. We believe we are adequately insured with respect to our operations.

        We are routinely involved in various legal matters arising from the normal course of business for which no provision has been made in the financial statements. While the outcome of these proceedings

E-98



PetroLogistics LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

17. Commitments and Contingencies (Continued)

cannot be predicted with certainty, we believe that these proceedings, when resolved, will not have a material adverse effect on our results of operations, financial position, or liquidity.

18. Subsequent Events

        In January 2014, we granted 212,372 phantom units to our employees under our Long-Term Incentive Plan with a grant date fair value of $12.00 per unit or approximately $2.5 million. These phantom units will vest on the third anniversary of the grant date so long as the award recipient remains continuously employed by the General Partner.

        On February 3, 2014, the General Partner approved a distribution to common unitholders of record as of February 18, 2014. The distribution of 30 cents per common unit was paid on February 25, 2014.

        In March 2014, we received notice of a lawsuit filed against us for liability involving personal injuries sustained in February 2014 by a contractor's employee working at our facility. Our third-party contracts contain indemnification clauses for incidents of this nature, including an obligation of the contractor to indemnify and defend us with respect to the applicable lawsuit. We also carry general liability insurance, subject to a deductible. We do not expect the cost of a settlement or eventual judgment, if any, to be material to our financial position or results of operations.

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

        None.

Disclosure Controls and Procedures

        We maintain written "disclosure controls and procedures," which we refer to as our "DCP." Our DCP is designed to help ensure that (i) information required to be disclosed by us in reports that we file under the Securities Exchange Act of 1934 (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and (ii) such information is accumulated and communicated to management, including our Executive Chairman, our Chief Executive Officer, our Chief Financial Officer and our General Counsel, to allow for timely decisions regarding required disclosure.

        Applicable SEC rules require an evaluation of the effectiveness of the design and operation of our DCP. Management, under the supervision and with the participation of our Executive Chairman, President and Chief Executive Officer, Chief Financial Officer and General Counsel, has evaluated the effectiveness of the design and operation of our DCP as of the end of the period covered by this report, and has found our DCP to be effective in providing reasonable assurance of the timely recording, processing, summarization and reporting of information, and in the accumulation and communication of information to management to allow for timely decisions with regard to required disclosure.

Internal Control over Financial Reporting

        Management is responsible for establishing and maintaining adequate internal control over financial reporting. "Internal control over financial reporting" is a process designed by, or under the supervision of, our Executive Chairman, our Chief Executive Officer and our Chief Financial Officer, and effected by the board of directors of our General Partner, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The management of our General Partner, including our Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2013, based on the framework in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, management concluded that our internal control over financial reporting was effective at the reasonable assurance level as of December 31, 2013.

        Although we have made various enhancements to our controls, there have been no changes in our internal control over financial reporting during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

        Ernst & Young LLP, a registered public accounting firm, has audited the consolidated financial statements included in this report and has issued an attestation report on our internal control over financial reporting. The attestation report of our registered public accounting firm and management's report on our internal control over financial reporting are set forth in "Item 8. Financial Statements and Supplementary Data" and are incorporated herein by reference.

Certifications

        The certifications of our Executive Chairman, our Chief Executive Officer and our Chief Financial Officer pursuant to Exchange Act rules 13a-14(a) and 15d-14(a) are filed with this report as Exhibits 31.1, 31.2 and 31.3. The certifications of our Executive Chairman, our Chief Executive Officer

E-100


and our Chief Financial Officer pursuant to 18 U.S.C. 1350 are furnished with this report as Exhibits 32.1, 32.2 and 32.3.

        There was no information that was required to be disclosed in a report on Form 8-K during the fourth quarter of 2013 that has not previously been reported.


PART III

Item 10.    Directors, Executive Officers and Corporate Governance.

Code of Business Conduct and Ethics

        Our General Partner has adopted a Code of Business and Ethics Conduct for its employees, officers and directors, which covers a wide range of business practices and procedures. In addition, our General Partner has adopted a Financial Code of Ethics applicable to our principal executive officer, principal financial officer and principal accounting officer or controller and persons performing similar functions (senior financial officers). Copies of such Codes are available on our website http://www.petrologistics.com, and copies will be mailed, without charge, upon written request to PetroLogistics LP, 600 Travis Street, Houston, TX 77002, Attn: General Counsel and Corporate Secretary. We intend to disclose any amendments to or waivers of the Codes on behalf of our senior financial officers on our website, at http://www. petrologistics.com promptly following the date of the amendment or waiver.

Our Management

        Our General Partner manages our operations and activities subject to the terms and conditions specified in our partnership agreement. Our General Partner will be indirectly owned by our sponsors, certain of our executive officers and certain of its employees. The operations of our General Partner in its capacity as general partner are managed by its board of directors. Actions by our General Partner that are made in its individual capacity will be made by our sponsors, as indirect owners of a controlling interest in our General Partner, and not by the board of directors of our General Partner. The board of directors of our General Partner is not elected by our unitholders and will not be subject to re-election on a regular basis in the future. The executive officers of our General Partner will manage our day-to-day activities consistent with the policies and procedures adopted by the board of directors of our General Partner.

        Limited partners will not be entitled to elect the directors of our General Partner or directly or indirectly participate in our management or operation. Our partnership agreement contains various provisions which replace default fiduciary duties under applicable law with contractual corporate governance standards. Our General Partner will be liable, as a general partner, for all of our debts (to the extent not paid from our assets), except for indebtedness or other obligations that are made expressly non-recourse to it. Our General Partner therefore may cause us to incur indebtedness or other obligations that are non-recourse to it. Our credit facilities are non-recourse to our General Partner.

        Whenever our General Partner makes a determination or takes or declines to take an action in its individual, rather than representative, capacity, it is entitled to make such determination or to take or decline to take such other action free of any fiduciary duty or obligation whatsoever to us, any limited partner or assignee, and it is not required to act in good faith or pursuant to any other standard imposed by our partnership agreement or under Delaware law or any other law. Examples include the exercise of its call right, its voting rights and its determination whether or not to consent to any merger or consolidation of the partnership. Actions by our General Partner that are made in its individual

E-101


capacity will be made by our sponsors, as indirect owners of a controlling interest in our General Partner, and not by its board of directors.

        As a publicly traded partnership, we qualify for, and intend to rely on, certain exemptions from the NYSE's corporate governance requirements, including the requirement that a majority of the board of directors of our General Partner consist of independent directors and the requirement that the board of directors of our General Partner have a nominating/corporate governance committee that is composed entirely of independent directors. While not required by NYSE rules, the board of directors of our General Partner has a compensation committee, however, our compensation committee may not be composed entirely of independent directors.

        As a result of these exemptions, our General Partner's board of directors is not comprised of a majority of independent directors, our General Partner's compensation committee is not comprised entirely of independent directors and our General Partner's board of directors does not currently intend to establish a nominating/corporate governance committee. Accordingly, unitholders will not have the same protections afforded to equityholders of companies that are subject to all of the corporate governance requirements of the NYSE.

Independence Determination and Audit Committee

        Pursuant to the NYSE listing standards, a director will be considered independent if the board determines that he or she does not have a material relationship with our General Partner or us (either directly or indirectly as a partner, unitholder or officer of an organization that has a material relationship with our General Partner or us) and otherwise meets the board's stated criteria for independence. The NYSE listing standards specify the criteria by which the independence of directors will be determined, including guidelines for directors and their immediate family members with respect to employment or affiliation with us or with our independent public accountants.

        The board of directors of our General Partner has an audit committee that, among other things, oversees, reviews, acts on and reports to the board of directors of our General Partner on various auditing and accounting matters, including: the selection of our independent accountants, the scope of our audits, fees to be paid to the independent accountants, the performance of our independent accountants and our accounting practices. In addition, the audit committee oversees our compliance programs relating to the legal and regulatory requirements as they relate to financial reporting.

        Our audit committee is comprised of three directors, John B. Walker, Phillip D. Kramer and Hallie Vanderhider. Our board has determined that audit committee members satisfy the independence standards established by the NYSE. Mr. Kramer qualifies as an "audit committee financial expert" for purposes of SEC rules and regulations. Our audit committee operates pursuant to a written charter, an electronic copy of which is available on our website at http://www.petrologistics.com.

Other Committees

        Our partnership agreement provides the board of directors of our General Partner the right to establish a conflicts committee, comprised of independent directors, to consider matters affecting the Partnership or any of its affiliates whenever a potential conflict of interest exists or arises. Any matters approved by the conflicts committee will be conclusively deemed to be in good faith to us, approved by all of our partners and not a breach by our General Partner of any duties it may owe us or our unitholders. The members of the conflicts committee may not be officers or employees of our General Partner or any person controlling our General Partner, including Lindsay Goldberg and York Capital, and must meet the independence standards established by the NYSE and the Exchange Act to serve on an audit committee of a board of directors, along with other requirements in our partnership agreement. Our audit committee may also serve as the conflicts committee. If the board of directors of our General Partner does not seek approval from the conflicts committee, and the board of directors of

E-102


our General Partner approves the resolution or course of action taken with respect to the conflict of interest, then it will be presumed that, in making its decision, the board of directors of our General Partner acted in good faith, and in any proceeding brought by or on behalf of us or any unitholder, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.

        The board of directors of our General Partner has a compensation committee that establishes salaries, incentives and other forms of compensation for officers and certain other employees of our General Partner. The compensation committee operates pursuant to a written charter. Our compensation committee is comprised of Lance L. Hirt and John B. Walker.

Board Leadership Structure and Role in Risk Oversight

        David Lumpkins serves as a co-principal executive officer and as Executive Chairman. Our General Partner's board of directors has no policy with respect to the separation of the office of chairman and the office of chief executive officer. Our General Partner has determined that this leadership structure represents an efficient and effective arrangement and that our leadership structure is appropriate in light of our ownership structure. In 2013, Mr. Phillip D. Kramer was selected as our lead independent director and he continues to serve in that role. In such role, Mr. Kramer presides at executive sessions of the independent directors. Our board regularly holds meetings of the non-management directors and Mr. Lance Hirt acts as the chair of such meetings.

        The management of enterprise-level risk may be defined as the process of identification, management and monitoring of events that present opportunities and risks with respect to creation of value for our unitholders. The board of directors of our General Partner has delegated to management the primary responsibility for enterprise-level risk management, while the board has retained responsibility for oversight of management in that regard. Management provides an enterprise-level risk assessment to the board of directors of our General Partner at least once every year.

Non-Management Executive Sessions and Shareholder Communications

        NYSE listing standards require regular executive sessions of the non-management directors of a listed company, and an executive session for independent directors at least once a year. The board regularly holds meetings of the non-management directors and the independent directors met in December 2013.

        Interested parties can communicate directly with non-management directors by mail in care of the General Counsel and Secretary at PetroLogistics LP, 600 Travis Street, Suite 3250, Houston, Texas 77002. Such communications should specify the intended recipient or recipients. Commercial solicitations or communications will not be forwarded.

Meetings and Other Information

        All of our directors attended at least 75% of the aggregate number of meetings of the board of directors and the committees of the board on which the director served.

        Our Audit Committee Charter and Governance Guidelines, as well as our Code of Business and Ethics Conduct and our Financial Code of Ethics, each of which applies to our principal executive officer, principal financial officer and principal accounting officer, are available on our Internet website at http://www.petrologistics.com, and a copy will be mailed without charge, upon written request, to PetroLogistics LP, 600 Travis Street, Houston, TX 77002, Attn: General Counsel and Corporate Secretary. We intend to disclose any amendment to or waiver of the Codes on behalf of an executive officer or director either on our Internet website or in an 8-K filing. Our first annual CEO certification as required by Section 303A.12(a) of the NYSE's Listed Company Manual must be submitted to the NYSE within 30 days of filing our 2012 Annual Report on Form 10-K.

E-103


Audit Committee Report

        The audit committee of PetroLogistics GP LLC oversees the Partnership's financial reporting process on behalf of the board of directors. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls.

        In fulfilling its oversight responsibilities, the audit committee reviewed and discussed with management the audited financial statements contained in this Annual Report on Form 10-K.

        The Partnership's independent registered public accounting firm, Ernst & Young LLP, is responsible for expressing an opinion on the conformity of the audited financial statements with accounting principles generally accepted in the United States of America. The audit committee reviewed with Ernst & Young LLP the firm's judgment as to the quality, not just the acceptability, of the Partnership's accounting principles and such other matters as are required to be discussed with the audit committee under generally accepted auditing standards.

        The audit committee discussed with Ernst & Young LLP the matters required to be discussed by Statement of Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board. The committee received written disclosures and the letter from Ernst & Young LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young LLP's communications with the audit committee concerning independence, and has discussed with Ernst & Young LLP its independence from management and the Partnership.

        Based on the reviews and discussions referred to above, the audit committee recommended to the board of directors that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2013, for filing with the SEC.

Compensation Discussion and Analysis (CD&A)

        Our General Partner has the sole responsibility for conducting our business and for managing our operations, and its board of directors and officers make decisions on our behalf. Our General Partner has formed a compensation committee (the compensation committee) to determine the compensation of the officers and directors of our General Partner, including the named executive officers.

        This compensation discussion and analysis, or CD&A, discusses the compensation paid to our executive officers and provides information about the compensation objectives and policies for these individuals. The CD&A is intended to place in perspective the information contained in the executive compensation tables that follow this discussion. This CD&A provides a general description of our compensation program and specific information about its various components.

        Throughout this discussion, the following individuals are referred to as the "named executive officers" and are included in the Summary Compensation Table:

        Our future success and the ability to create long-term value for our unitholders depends on our ability to attract, retain, and motivate the executives necessary to manage our business. We employ a compensation philosophy that emphasizes pay for performance. We believe that compensation should:

E-109


        In supporting our objectives, the compensation committee considers the use of both cash and equity-based compensation in the total direct compensation package provided to our named executive officers. The compensation committee is currently considering a more formal policy with respect to our cash bonus and long-term equity programs for our executive officers. See "Compensation Discussion and Analysis—Actions Taken Regarding 2014 Compensation" below.

        All compensation decisions for the named executive officers are determined by the compensation committee. The compensation committee seeks to provide a total compensation package designed to drive performance and reward contributions in support of our business strategies and to attract, motivate and retain high quality talent with the skills and competencies required by us. In determining compensation for our named executive officers, our compensation committee reviews the compensation practices of our peer companies and compensation data from our industry generally to the extent the competition for executive talent is broader than a group of selected peer companies. In addition, the compensation committee reviews and, in certain cases, participates in, various relevant compensation surveys and consults with compensation consultants with respect to determining compensation for the named executive officers.

        Role of Compensation Consultants.    During 2013, the compensation committee retained BDO USA, LLP ("BDO") as its independent compensation consultant for matters related to executive compensation. BDO prepared a report including market data with respect to peer company composition and compensation. The compensation committee has engaged BDO to advise it with respect to the development of a long-term equity compensation program for our executive officers. See "Compensation Discussion and Analysis—Actions Taken Regarding 2014 Compensation" below.

        Role of Executive Officers.    For 2013, base salaries and bonus amounts of our named executive officers, excluding the Executive Chairman and President and Chief Executive Officer, were proposed by our Executive Chairman and our President and Chief Executive Officer and approved by our compensation committee. Base salaries and bonus amounts of our Executive Chairman and our President and Chief Executive Officer for 2013 were determined by our compensation committee. For 2014 and future years, we expect that our Executive Chairman and our President and Chief Executive Officer will continue to provide periodic recommendations to the compensation committee regarding the compensation of the other named executive officers.

        The following discussion regarding the elements of compensation provided to the named executive officers reflects our current philosophy concerning the division of the elements of senior management employees' compensation packages. For the fiscal year ended December 31, 2013, the principal elements of compensation for the named executive officers were the following:

E-110


        Base Salary.    Base salary is the fixed annual compensation we pay to each named executive officer for performing specific job duties. It represents the minimum income a named executive officer may receive for a full year's performance.

        The compensation committee reviews base salaries on an annual basis, in consultation with the Executive Chairman and the President and Chief Executive Officer with respect to the base salaries of the other named executive officers, and may adjust base salaries upon consideration of any factors they deem relevant, including, but not limited to: (i) any increase or decrease in the executive's responsibilities, (ii) the executive's job performance, and (iii) the level of compensation paid to executives of other companies with which we compete for executive talent, as estimated based on publicly available information, compensation surveys, the experience of the members of the compensation committee and our Executive Chairman and President and Chief Executive Officer, and other relevant data.

        After considering the factors listed above, effective January 1, 2013, the compensation committee authorized the following base salaries for our named executive officers:

Name
  Effective
January 1, 2013
  2012 Salary  

David Lumpkins

  $ 450,000   $ 400,000  

Nathan Ticatch

    450,000     400,000  

Sharon Spurlin

    300,000     260,000  

Richard Rice

    350,000     350,000  

Hank Jeans

    240,000     240,000  

Randy Miller

    275,000     250,000  

        The compensation committee authorized these base salaries for the named executive officers in order to recognize the job performance of our named executive officers.

        Actions taken by the compensation committee regarding base salaries for 2014 are discussed below under "Compensation Discussion and Analysis—Actions Taken Regarding 2014 Compensation."

        Discretionary Bonus Awards.    Historically, annual bonuses have been discretionary. We review annual cash bonus awards for the named executive officers at the end of each fiscal year to determine award payments for that fiscal year. Currently we do not have a practice of establishing target bonuses for our named executive officers. When determining the appropriate bonus payments each year we consider both company and individual performance; however, at present there are no pre-established formulas, metrics or goals against which we measure the company or individual performance factors. We believe that an annual bonus program based on performance motivates management to achieve key short-term business objectives and aligns executives' interests with our unitholders' interests.

        The bonuses for 2013 performance (the 2013 Bonuses) were approved by the compensation committee following a year-end review of the individual performance of the executive officer in question and our overall performance for 2013 and were paid in early 2014. While the compensation committee takes all relevant information into account, the material factors considered when evaluating each executive's individual performance for purposes of the 2013 Bonuses included: (i) their contribution to our overall success, (ii) any increase or decrease in the level of their responsibilities and duties, and (iii) the overall quality of their job performance during the year. The amount of each named executive officer's 2013 Bonus was determined in the full discretion of our compensation committee after taking all of the factors enumerated above into consideration and determining what amount seemed fair and reasonable under the facts and circumstances. The 2013 Bonuses are reported in the "Bonus" column of the Summary Compensation Table for 2013.

E-111


        Long-Term Equity-Based Incentive Awards.    In order to incentivize our executive officers to continue to improve our business, our General Partner adopted the Long-Term Incentive Plan ("LTIP") for employees, consultants and directors of our General Partner and its affiliates, who perform services for us. Each of the named executive officers is eligible to participate in the LTIP. The LTIP provides for the grant of unit awards, restricted units, phantom units, unit options, unit appreciation rights, distribution equivalent rights, substitute awards and other unit-based awards. These awards are intended to align the interests of employees (including the named executive officers) with those of our unitholders and to give those employees the opportunity to share in our long-term performance.

        The compensation committee may approve grants of awards under the LTIP on terms that it determines appropriate, including the period during and the conditions on which the award will vest. The compensation committee determined not to make any awards under the LTIP to our named executive officers during 2013; however, certain named executive officers held outstanding unit-based awards during 2013 that were awarded under the LTIP during 2012. These outstanding unit-based awards are subject to service-based conditions and vest in annual installments over a three year period, subject to continued service by the named executive officer through each applicable vesting date. The outstanding unit-based awards will be settled upon vesting in the form of common units. In addition, these outstanding unit-based awards include distribution equivalent rights, which provide that the award recipient receives quarterly distributions on the number of common units underlying each outstanding unit-based award at the time such distributions are declared and paid to unitholders generally. The amounts received with respect to the distribution equivalent rights comprise a portion of the compensation for these named executive officers and are taken into account by the compensation committee in evaluating total compensation for the officers. The amounts received during 2013 with respect to the distribution equivalent rights are reported in the "All Other Compensation" column of the Summary Compensation Table.

        For 2014, the compensation committee recommended and the board of directors approved the grant of phantom units to certain of the named executive officers. See "Compensation Discussion and Analysis—Actions Taken Regarding 2014 Compensation" below.

        Employee Benefits.    In addition to the elements of compensation previously discussed, the named executive officers are eligible for the same health, welfare and other employee benefits as are available to all employees generally, which include medical and dental insurance, short and long-term disability insurance, life insurance, and a 401(k) profit sharing plan. The 401(k) profit sharing plan permits all eligible employees, including the named executive officers, to make voluntary salary deferrals, subject to applicable tax limitations. The 401(k) profit sharing plan also provides a dollar-for-dollar safe harbor matching contribution on the first 6% of eligible compensation contributed to the plan as salary deferrals, which is 100% vested at all times. Discretionary profit sharing contributions are made to the 401(k) profit sharing plan for employees who have completed one year of service and are employed on the last day of the plan year, and these contributions are based upon age and a target rate and are typically paid in the first quarter of the following year. In addition, minimal perquisites have historically been provided to our named executive officers, as approved on a case-by-case basis, and the annual cost of such personal benefits provided to each named executive officer has been less than $10,000. We do not sponsor any defined benefit pension plan or nonqualified deferred compensation arrangements at this time.

Severance and Change in Control Arrangements

        Except as provided pursuant to the outstanding unit-based awards granted under our LTIP, we did not have any employment or other agreements in place with our named executive officers providing for severance and/or change in control benefits during 2013 and, to date in 2014, our General Partner has not adopted any arrangements that would provide severance and/or change in control benefits to our named executive officers. Our General Partner may change this policy in the future. The termination

E-112


and change in control provisions of the unit-based awards granted in 2012 under our LTIP are described below in the section titled "Potential Payments upon Termination or Change in Control."

        The compensation committee, with input from its independent compensation consultant BDO, is currently analyzing our 2014 compensation program for the named executive officers and is considering potential modifications to such program for subsequent years so that our annual compensation arrangements create a greater alignment between our executive officers and our unitholders. As part of the review the compensation committee is considering certain modifications to our existing arrangements including the addition of metrics-based performance measures. To date, however, no specific decisions have been made by the compensation committee regarding 2014 bonuses.

        The compensation committee has authorized the following base salaries for our named executive officers, effective January 1, 2014:

 
  Effective
January 1, 2014
  2013 Salary  

David Lumpkins

  $ 475,000   $ 450,000  

Nathan Ticatch

    475,000     450,000  

Sharon Spurlin

    320,000     300,000  

Richard Rice

    350,000     350,000  

Hank Jeans

    255,000     240,000  

Randy Miller

    290,000     275,000  

        The compensation committee authorized these base salaries for the named executive officers in order to recognize the job performance of our named executive officers.

        The compensation committee also granted phantom units to certain of our named executive officers on January 15, 2014. These phantom units will cliff vest in full on January 15, 2017, provided the officer remains continuously employed by us until that date. The awards have accompanying dividend equivalent rights, which provide that the award recipient receives quarterly distributions on the common units underlying the phantom units as and when declared by the Partnership.

Tax Considerations

        With respect to the deduction limitations under Section 162(m) of the Internal Revenue Code, (the Code) we are a limited partnership and do not meet the definition of a "corporation" under Section 162(m). Therefore, we are not subject to the $1 million deduction limitation imposed by Section 162(m).

Includes the following unit-based awards granted by us:

in May 2012 to Mr. Jeans, of which one third vested on May 9, 2013, one third vests on May 9, 2014, and the remaining one third vests on May 9, 2015, subject to continued employment on each applicable vesting date;

in November 2012 to Mr. Rice, of which one third vested on November 1, 2013, one third vests on November 1, 2014, and the remaining one third vests on November 1, 2015, subject to continued employment on each applicable vesting date; and

in December 2012 to Ms. Spurlin, of which one third vested on November 1, 2013, one third vests on November 1, 2014, and the remaining one third vests on November 1, 2015, subject to continued employment on each applicable vesting date. The compensation committee changed the vesting dates of Ms. Spurlin's award from December to November in order to reduce the recordkeeping burden associated with multiple vesting dates. The termination and change in control provisions of these unit-based awards held by Messrs. Jeans and Rice and Ms. Spurlin are described below in the section titled "Potential Payments upon Termination or Change in Control."

Option Exercises and Units Vested in the 2013 Fiscal Year

        The following table provides information regarding the vesting in 2013 of unit-based awards held by certain named executive officers. Messrs. Lumpkins, Ticatch, and Miller did not hold any outstanding unit-based awards under the LTIP that vested in 2013. To date, we have not granted any unit options.

Includes the number of common units withheld to satisfy tax withholding obligations with respect to vesting of the awards. After deducting the number of common units withheld, the net number of common units actually received by each named executive officer was as follows: (a) Ms. Spurlin—18,831 common units (with a value realized of $240,472), (b) Mr. Rice—53,234 common units (with a value realized of $679,798), and (c) Mr. Jeans—21,367 common units (with a value realized of $273,284).

(2)
The value realized upon vesting of unit-based awards is based on the following:

A closing price per share of our common stock of $12.79, for awards that vested on May 9, 2013.

A closing price per share of our common stock of $12.77, for awards that vested on November 1, 2013.

Pension Benefits

        Currently, our General Partner does not, and does not intend to, provide traditional defined benefit pension benefits to the employees, including the named executive officers. Our General Partner may change this policy in the future.

Nonqualified Deferred Compensation

        Currently, our General Partner does not, and does not intend to, sponsor or adopt a nonqualified deferred compensation plan. Our General Partner may change this policy in the future.

Potential Payments upon Termination or Change in Control

        As of December 31, 2013, the only arrangements in place with our named executive officers providing such individuals with severance or change in control benefits were the arrangements included as part of the outstanding unit-based awards under our LTIP. To date, the compensation committee of our General Partner has not adopted any other arrangements that will provide severance or change in control benefits to our named executive officers.

        The outstanding unit-based awards under our LTIP become fully vested upon a named executive officer's death or the occurrence of a change in control. For purposes of the unit-based awards, "change in control" means (i) a person or group becomes the beneficial owner of 50% or more of the voting power of the voting securities of the Partnership or of the General Partner, (ii) the limited partners of the Partnership or the General Partner approve a plan of complete liquidation of the Partnership or the General Partner, (iii) the sale or other disposition by the Partnership or the General

        The following table summarizes the value that would be realized by the named executive officers under the outstanding unit-based awards assuming their employment terminated under the specified circumstances or a change in control occurred, in each case, on December 31, 2013. For these purposes, our common unit price was assumed to be $11.65, which was the closing price per unit on December 31, 2013.

Director Compensation

        Directors of our General Partner who are not officers, employees or directors of the Partnership, Lindsay Goldberg, York Capital or their affiliates (referred to as the independent directors) receive compensation for their services. Independent directors each receive an annual retainer fee in cash of $50,000 plus an additional $1,000 for each board meeting attended. The audit committee chair receives an additional fee of $12,000 per year. The compensation committee chair, if an independent director, receives an additional fee of $7,200 per year. All fees are pro-rated based on the amount of time each director has served since his appointment.

        In addition, independent directors also receive an annual award of phantom units pursuant to the LTIP with a value of approximately $100,000 on the date of grant. Per the terms of the LTIP, the phantom awards contain distribution equivalent rights, which provide that the award recipient receives quarterly distributions on the common units underlying the phantom units as and when declared by the Partnership. The phantom units vest over a one year period, which is typically tied to the anniversary of the date such holder joined the board of directors, subject to the director's continued service as a member of the board of directors during that period, except that the unit-based awards granted on July 17, 2013, to Mr. Kramer will vest on May 9, 2014, the same vesting date as for the awards granted to the other independent board members.

        Independent directors are reimbursed for certain out-of-pocket expenses in connection with attending meetings of the board of directors or committees, although no such reimbursements were made during 2013. Each director is indemnified by us for actions associated with being a director to the fullest extent permitted under Delaware law.

        The following table sets forth the compensation received by each independent director of our General Partner for the year ended December 31, 2013.

Mr. Walker and Ms. Vanderhider were each granted 7,819 phantom units on May 9, 2013, and Mr. Kramer was granted 7,651 phantom units on July 17, 2013, all pursuant to the LTIP, and all which remained outstanding and unvested on December 31, 2013. The number of phantom units granted was based on the closing market price of our common units on the date of the grant, which was $12.79 per unit for the grants priced on May 9, 2013 and $13.07 per unit for the grant priced on July 17, 2013. These unit-based awards will become fully vested on May 9, 2014, provided the director continues to serve as a director of our General Partner on such date. The outstanding phantom units become fully vested upon a named director's death or the occurrence of a change in control. The dollar amounts in the table reflect the aggregate grant date fair value of the phantom units granted in 2013, computed in accordance with FASB ASC Topic 718. See note 2 to our consolidated financial statements for the fiscal year ended December 31, 2013, for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards. As of December 31, 2013, these are the only phantom units held by our independent directors.

(3)
Amounts in this column reflect the payment of distributions in 2013 pursuant to distribution equivalent rights with respect to phantom unit awards granted under the LTIP.

Compensation Practices as They Relate to Risk Management

        We believe our compensation programs do not encourage excessive and unnecessary risk taking by executive officers (or other employees of our General Partner). Short-term annual incentives are paid pursuant to discretionary bonuses enabling the compensation committee to assess the actual behavior of the employees as it relates to risk taking in awarding a bonus. Further, the use of equity-based long-term incentive compensation under our LTIP serves our compensation program's goal of aligning the interests of executives and unitholders, thereby reducing the incentives for unnecessary risk taking.

Item 13.    Certain Relationships and Related Transactions and Director Independence.

        For a discussion of director independence, see "Item 10. Directors and Executive Officers and Corporate Governance."

Our General Partner

        Our General Partner manages our operations and activities subject to the terms and conditions specified in our partnership agreement. Our General Partner will be indirectly owned by our sponsors, certain of our executive officers and certain of its employees. The operations of our General Partner in its capacity as general partner are managed by its board of directors. Actions by our General Partner that are made in its individual capacity will be made by our sponsors, as indirect owners of a controlling interest in our General Partner, and not by the board of directors of our General Partner. The board of directors of our General Partner is not elected by our Unitholders and will not be subject to re-election on a regular basis in the future. The executive officers of our General Partner will manage our day-to-day activities consistent with the policies and procedures adopted by the board of directors of our General Partner.

        Limited partners will not be entitled to elect the directors of our General Partner or directly or indirectly participate in our management or operation. Our partnership agreement contains various provisions which replace default fiduciary duties under applicable law with contractual corporate governance standards. Our General Partner will be liable, as a general partner, for all of our debts (to the extent not paid from our assets), except for indebtedness or other obligations that are made expressly non-recourse to it. Our General Partner therefore may cause us to incur indebtedness or other obligations that are non-recourse to it. Our credit facilities are non-recourse to our General Partner.

        Whenever our General Partner makes a determination or takes or declines to take an action in its individual, rather than representative, capacity, it is entitled to make such determination or to take or decline to take such other action free of any fiduciary duty or obligation whatsoever to us, any limited partner or assignee, and it is not required to act in good faith or pursuant to any other standard imposed by our partnership agreement or under Delaware law or any other law. Examples include the exercise of its call right, its voting rights and its determination whether or not to consent to any merger or consolidation of the Partnership. Actions by our General Partner that are made in its individual capacity will be made by our sponsors, as indirect owners of a controlling interest in our General Partner, and not by its board of directors.

        As a publicly traded partnership, we qualify for, and intend to rely on, certain exemptions from the NYSE's corporate governance requirements, including the requirement that a majority of the board of directors of our General Partner consist of independent directors and the requirement that the board of directors of our General Partner have a nominating/corporate governance committee that is composed entirely of independent directors. While not required by NYSE rules, the board of directors of our General Partner has a compensation committee, however, our compensation committee is not composed entirely of independent directors.

        As a result of these exemptions, our General Partner's board of directors is not comprised of a majority of independent directors, our General Partner's compensation committee is not comprised entirely of independent directors and our General Partner's board of directors does not currently intend to establish a nominating/corporate governance committee. Accordingly, unitholders will not have the same protections afforded to equityholders of companies that are subject to all of the corporate governance requirements of the NYSE.

E-121


Transactions with Related Parties

Contribution Agreement

        On March 30, 2012, we entered into a contribution, conveyance and assumption agreement with Propylene Holdings and PL Manufacturing pursuant to which Propylene Holdings contributed PL Propylene to us, and we assumed all liabilities (including unknown and contingent liabilities) associated with owning PL Propylene after its contribution to us.

Omnibus Agreement

        On May 9, 2012, we, the General Partner, Propylene Holdings, PL Propylene and PL Manufacturing LLC entered into an omnibus agreement (the "omnibus agreement"). Pursuant to the omnibus agreement and a related pledge agreement (the "pledge agreement"), we allocated all of our benefits and obligations under the propane swaps to PL Manufacturing and the PL Manufacturing Members.

        On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

        While we did not bear any of the costs nor receive any of the benefits of the propane swaps, we remained a party to the propane swaps, and were obligated to make payments to the propane swap counterparties as they come due and to post any collateral as required, under the terms of the propane swap agreement. As a result, we continued to record the fair value of the propane swaps on our balance sheet with the related gains or losses reflected in our statement of comprehensive income (loss). To the extent that the Partnership made payments under the propane swaps, PL Manufacturing and the PL Manufacturing Members were responsible for making quarterly capital contributions in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. During the years ended December 31, 2013 and 2012, PL Manufacturing and the PL Manufacturing Members paid approximately $93.2 million and $47.0 million, respectively, to us as reimbursement for realized losses on the propane swaps with the 2012 period pro-rated from May 9, 2012, the closing date of our initial public offering (the "IPO"), through December 31, 2012. See Note 3 regarding the IPO.

        In connection with the termination of the propane swaps, we paid a cancellation payment of $34.4 million in May 2013, of which $5.4 million was reimbursed through a reduction in the distribution paid to PL Manufacturing and the PL Manufacturing Members in May 2013 in accordance with the terms of the omnibus agreement. The remaining $29.0 million was settled with cash held as collateral by the propane swap counterparty and was immediately reimbursed by PL Manufacturing and the PL Manufacturing Members. During the years ended December 31, 2013 and 2012, we recorded capital contributions of approximately $61.4 million and $78.9 million, respectively, for the reimbursement of the realized losses on the propane swaps and the reimbursement of the termination payment by PL Manufacturing and the PL Manufacturing Members. We received the final reimbursement for realized losses from PL Manufacturing and the PL Manufacturing Members on August 14, 2013, at which time the omnibus agreement terminated in accordance with its terms.

Brock Maintenance Contracts

        In 2008, we entered into a series of contracts with Brock Maintenance, Inc., or Brock, an entity owned by Lindsay Goldberg. Pursuant to these contracts, Brock has provided, and continues to provide us with painting, scaffolding, fireproofing and insulation and asbestos abatement services as needed.

E-122


        The value of each contract may be adjusted based upon ongoing costs incurred and services provided by Brock, subject to our consent. During the years ended December 31, 2013, 2012 and 2011, the total amounts paid to Brock were $2.9 million, $1.5 million, and $2.8 million, respectively.

Registration Rights Agreement

        In connection with our IPO, we entered into a registration rights agreement with our sponsors, David Lumpkins and Nathan Ticatch, pursuant to which we may be required to register the sale of the common units they hold. Under the registration rights agreement, our sponsors will have the right to request that we register the sale of common units held by them and our sponsors, David Lumpkins and Nathan Ticatch have the right to require us to make available shelf registration statements permitting sales of common units into the market from time to time over an extended period, subject to certain limitations. In addition, our sponsors and Messrs. Lumpkins and Ticatch will have the ability to exercise certain piggyback registration rights with respect to their securities if we elect to register any of our equity interests. The registration rights agreement also includes provisions dealing with holdback agreements, indemnification and contribution and allocation of expenses. All of our common units held by our sponsors and any permitted transferee will be entitled to these registration rights.

        In November 2013, we entered into a Reimbursement Agreement with Lindsay Goldberg pursuant to which Lindsay Goldberg agreed to reimburse us for 50% of certain costs we incurred under a development agreement with a third party. In December 2013, Lindsay Goldberg reimbursed us $0.7 million of project development costs which we recorded as a reduction in development expense in our consolidated statements of comprehensive income (loss) for the year ended December 31, 2013. We ultimately elected not to pursue the potential development opportunity and anticipate receiving no further payments under the terms of the Reimbursement Agreement.

Review and Ratification of Transactions with Related Parties

        Our partnership agreement provides the board of directors of our General Partner the right to establish a conflicts committee, comprised of independent directors, to consider matters affecting the Partnership or any of its affiliates whenever a potential conflict of interest exists or arises. Any matters approved by the conflicts committee will be conclusively deemed to be in good faith to us, approved by all of our partners and not a breach by our General Partner of any duties it may owe us or our Unitholders. The members of the conflicts committee may not be officers or employees of our General Partner or any person controlling our General Partner, including Lindsay Goldberg and York Capital, and must meet the independence standards established by the NYSE and the Exchange Act to serve on an audit committee of a board of directors, along with other requirements in our partnership agreement. Our audit committee may also serve as the conflicts committee. If the board of directors of our General Partner does not seek approval from the conflicts committee, and the board of directors of our General Partner approves the resolution or course of action taken with respect to the conflict of interest, then it will be presumed that, in making its decision, the board of directors of our General Partner acted in good faith, and in any proceeding brought by or on behalf of us or any unitholder, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption.

Pre-Approval Policy

        As discussed above, the board of directors of our General Partner has an audit committee that reviews our external financial reporting, engages our independent auditors and reviews the adequacy of our internal accounting controls. The audit committee has instituted policies that describe certain pre-approved non-audit services. We believe that the descriptions of services are designed to be sufficiently detailed as to particular services provided, such that (i) management is not required to exercise judgment as to whether a proposed service fits within the description and (ii) the audit committee knows what services it is being asked to pre-approve. The audit committee is informed of each engagement of the independent auditor to provide services under the respective policy. All services provided by our independent auditor for the year ended December 31, 2013, were approved in advance by the audit committee.

1. Organization and Nature of Operations

        As used in this report, the terms "PetroLogistics LP," "the Partnership," "we," "our," "us" or like terms, refer to PetroLogistics LP. References to PL Propylene refer to PL Propylene LLC, our sole operating subsidiary. References in this report to our "Sponsors" refer to Lindsay Goldberg LLC ("Lindsay Goldberg") and York Capital Management who collectively and indirectly own 84% of PetroLogistics GP (our "General Partner") and directly and indirectly own 63% of our common units.

        PetroLogistics LP is a Delaware limited partnership that was formed on June 9, 2011, by Propylene Holdings LLC ("Propylene Holdings") to own PL Propylene, a wholly-owned subsidiary of Propylene Holdings. The General Partner holds a non-economic interest in the Partnership.

        On March 30, 2012, Propylene Holdings contributed PL Propylene to PetroLogistics LP. Because this transaction was a transaction between entities under common control, the contributed assets and liabilities of PL Propylene were recorded in the consolidated financial statements at PL Propylene's historical cost. Prior to the contribution, PetroLogistics LP had no operations and nominal assets and liabilities.

        We currently own and operate the only U.S. propane dehydrogenation facility (the "facility") producing polymer grade and chemical grade propylene from propane. Propylene is used as one of the basic building blocks for petrochemicals in a variety of end uses, including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. In addition to propylene, the facility generates commercial quantities of the following by-products during the production process: hydrogen, C4 mix stream, and C5+ stream.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

        The interim consolidated financial statements and notes thereto have been prepared by management without audit according to the rules and regulations of the Securities and Exchange Commission ("SEC") and reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results for the periods presented. Such adjustments are of a normal recurring nature, unless otherwise disclosed. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been omitted pursuant to the SEC's rules and regulations. However, management believes that the disclosures presented herein are adequate to fairly present the information. All inter-company transactions and balances have been eliminated upon consolidation. The accompanying interim consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our annual report on Form 10-K as filed with the SEC on March 7, 2014.

Use of Estimates

        The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure

of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting periods. We review our estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates, and actual results could differ materially from those estimates. The results of operations of the Partnership for any interim period are not necessarily indicative of results for the full year.

Derivative Instruments

        Commencing October 2011 and through March 2012, we entered into commodity derivative contracts (the "propane swaps") with settlement dates in 2012 and 2013 to manage our exposure to commodity price risk with respect to propane, our sole feedstock. The propane swaps were designed to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our propane swaps were intended to act as a hedging (offset) mechanism against the volatility of energy commodity prices by allowing us to transfer some of the price risk to counterparties who were able and willing to bear it.

        Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC" or "Codification") Topic 815, Derivatives and Hedging ("ASC Topic 815"), addresses the accounting for derivative contracts. We entered into our commodity derivative contracts to economically hedge an exposure through a relationship that did not qualify for hedge accounting under ASC Topic 815. Our derivative contracts were recorded as derivative assets and liabilities, as applicable, at fair value on the consolidated balance sheets, and the associated unrealized gains and losses were recorded as current expense or income in the consolidated statements of comprehensive income. Unrealized gains or losses on commodity derivative contracts represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows in the consolidated statements of cash flows. Until settlement occurred, the changes in fair value of the propane swaps resulted in non-cash gains or losses being reported in our operating results as gain or loss on derivatives.

        On May 9, 2012, the General Partner, the Partnership, Propylene Holdings, PL Propylene and PL Manufacturing LLC ("PL Manufacturing") entered into an omnibus agreement (the "omnibus agreement"). Pursuant to the omnibus agreement and a related pledge agreement (the "pledge agreement"), we allocated all of our benefits and obligations under the propane swaps to PL Manufacturing and the owners of 100% of the issued and outstanding equity interests in PL Manufacturing (the "PL Manufacturing Members").

        On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

        While we did not bear any of the costs nor receive any of the benefits of the propane swaps, we remained a party to the propane swaps and were obligated to make payments to the propane swap counterparties as they came due and to post any collateral as required under the terms of the propane swap agreement. As a result, we continued to record the fair value of the propane swaps on our

consolidated balance sheets with the related gains or losses reflected in our consolidated statements of comprehensive income. To the extent that we made payments under the propane swaps, PL Manufacturing and the PL Manufacturing Members were responsible for making quarterly capital contributions in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. During the three months ended March 31, 2013, we recorded a capital contribution of approximately $22.1 million for the reimbursement of the realized losses on the propane swaps that we incurred in the first quarter of 2013.

        In connection with the termination of the propane swaps, we paid a cancellation payment of $34.4 million in May 2013, of which $5.4 million was reimbursed to us through a reduction in the distribution paid to PL Manufacturing and the PL Manufacturing Members in May 2013 in accordance with the terms of the omnibus agreement. The remaining $29.0 million was settled with cash held as collateral by the propane swap counterparty, and we were immediately reimbursed by PL Manufacturing and the PL Manufacturing Members. We received the final reimbursement for realized losses from PL Manufacturing and the PL Manufacturing Members on August 14, 2013, at which time the omnibus agreement terminated in accordance with its terms.

Equity-Based Compensation

        We recognize compensation expense related to unit-based awards granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures (see Note 6). The grant date fair value of the unit-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.

Fair Value of Financial Instruments

        We consider cash and cash equivalents, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable-related parties, and accrued liabilities to be financial instruments in which the carrying amounts represent fair value because of the short-term nature of the accounts.

        Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated or generally unobservable inputs. We make certain assumptions we believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. Credit risk of the Partnership and its counterparties is incorporated in the valuation of assets and liabilities. We believe we use valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

Senior notes

  $   $ 367,401   $   $ 365,000  

        The senior notes are deemed to be Level 2 financial instruments because the fair value is based on observable market data. At March 31, 2014 and December 31, 2013, the fair value of the senior notes was determined based on active trades and market corroborated data.

        There are no financial instruments that are split across the levels, and there have been no financial instruments that transferred between the levels during the three months ended March 31, 2014.

        We operate in one segment for the production and sale of propylene and related by-products. All of our operations are located in Houston, Texas.

        Net income per common unit for a given period is based on the distributions that are made to the unitholders plus an allocation of undistributed net income based on provisions of the partnership agreement, divided by the weighted average number of common units outstanding. The two-class method dictates that net income for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income as if all of the net income for the period had been distributed in accordance with the partnership agreement. Unit-based awards granted under the PetroLogistics Long-Term Incentive Plan (the "Long-Term Incentive Plan") are eligible for Distribution Equivalent Rights ("DERs"). To the extent that non-forfeitable DERs are awarded, the underlying nonvested unit-based awards are considered participating securities for purposes of determining net income per unit. Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and unit-based awards outstanding. Undistributed losses (including those resulting from distributions in excess of net income) are allocated to common units based on provisions of the partnership agreement. Undistributed losses are not allocated to nonvested unit-based awards as they do not participate in net

        Raw materials inventory consists primarily of propane. Work in progress inventory represents pipeline and plant fill inventory, which is a combination of propane and propylene. Finished goods inventory includes inventory stored at third party facilities pursuant to our propylene exchange and storage contracts. The exchange and storage contracts provide for storage capacity of 95 million pounds. Legal title and custody, control and risk of loss of finished goods inventory remains with us until the finished goods inventory is delivered to the customer pursuant to our propylene sales contracts.

4. Derivative Instruments

        Our business activities expose us to risks associated with unfavorable changes in the market price of propylene and propane. Commencing October 2011 and through March 2012, we entered into derivative transactions with the intent of reducing volatility in our cash flows due to fluctuations in the price of propane, our sole feedstock. Under the terms of the arrangement, for a portion of our propane consumption, we locked in the price of propane as a fixed percentage of the price of Brent crude oil (the "contractual percentage"). Beginning in January 2012, and at the conclusion of each month thereafter through the May 2013 cancellation date, we performed a calculation to determine the average actual price of propane for that month as a percentage of the average actual price of Brent crude oil for that month (the "actual percentage"). If the actual percentage exceeded the contractual percentage under the propane swaps, we were owed a sum by the propane swaps counterparty. If the contractual percentage exceeded the actual percentage under the propane swaps, we owed a sum to the propane swaps counterparty.

        On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members. See Note 2 regarding the omnibus agreement.

        As of March 31, 2014 and December 31, 2013, we do not have any outstanding commodity forward contracts to hedge our forecasted energy commodity purchases.

2012 Credit Facilities

        On March 27, 2012, PL Propylene, entered into a term loan facility of $350.0 million and a revolving credit facility of $120.0 million with Morgan Stanley Senior Funding, Inc., and the lenders party thereto (together, the "2012 credit facilities"). Borrowings under the 2012 credit facilities carried interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the term loan facility and the revolving credit facility ranged from 4.75% for loans bearing interest at the Alternate Base Rate to 5.75% for loans bearing interest at LIBOR. During the first quarter of 2013, the interest rate on the term loan was based on LIBOR, subject to the LIBOR floor of 1.25%, resulting in a rate of 7%.

        The revolving credit facility also included a commitment fee calculated at a rate per annum equal to 0.50% on the average daily unused portion of the commitments under the revolving credit facility. In addition, we paid an annual management fee for the term loan facility and the revolving credit facility. We were also required to pay a participation fee equal to the applicable margin for LIBOR loans, and a fronting fee to lenders participating in any letter of credit of 5.75%, and 0.125%, respectively.

        As required by our term loan facility, we entered into an interest rate protection agreement in July 2012 whereby we capped the three month LIBOR rate at 2.0% for up to $115.5 million on our term loan. The agreement terminated on March 27, 2014.

2013 Credit Facilities and Debt Refinancing

        On March 28, 2013, we and our wholly-owned finance subsidiary, PetroLogistics Finance Corp., co-issued jointly and severally $365.0 million of senior unsecured notes due 2020 (the "senior notes"), and we amended and extended our revolving credit facility (together with the senior notes, the "2013 credit facilities") from $120 million to $170 million with Morgan Stanley Senior Funding, Inc. (the "Agent"), and the lender parties thereto. We used the net proceeds from the issuance of the senior notes, after underwriting fees of $7.3 million, to (1) repay all borrowings outstanding under our term

loan facility in the amount of $347.4 million, (2) pay $6.9 million for the call premium and costs associated with the cancellation of our term loan facility and (3) pay $3.0 million in commitment fees on our revolver and approximately $0.4 million in transaction fees. The proceeds from the senior notes, the repayment of the term loan and the transaction fees were net settled with the Agent as presented in the consolidated statement of cash flows for the quarter ended March 31, 2013. In addition, we incurred approximately $1.3 million in third party transaction costs. The senior notes were issued at the par value of $365 million and are reported as long-term debt in our consolidated balance sheets at March 31, 2014 and December 31, 2013.We recorded total deferred financing costs of approximately $12.0 million in connection with the issuance of the senior notes and the amendment and extension of our revolving credit facility. Cash paid for deferred financing costs totaled approximately $1.3 million with the remaining portion of $10.7 million net settled with the Agent through the senior note proceeds. We amortize the deferred financing costs using the effective interest method over the terms of the underlying credit facilities.

        The 2013 credit facilities contain certain restrictive financial covenants, including limitations on our ability to incur additional debt and the requirement under the terms of our revolver to maintain a total senior secured leverage ratio, as defined, no greater than 2.0 to 1.0, but only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2013, the aggregate amounts outstanding under the revolving credit facility exceeds $120 million.

        The senior notes bear interest at a fixed rate of 6.25% per annum, payable on April 1 and October 1. The revolving credit facility bears interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the revolving credit facility ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greatest of the prime rate in effect and the federal funds effective rate in effect plus 1/2 of 1.0%. The revolving credit facility also contains a facility commitment fee at a rate of 0.50% per annum based on the daily unused amount of the commitment amount of $170 million payable in arrears on the last day of March, June, September and December of each year.

Amortization and Final Maturity.

        The senior notes have a maturity date of April 1, 2020. Prior to April 1, 2016, we may redeem all or part of the senior notes at a redemption price equal to the sum of 100% of the principal amount of the senior notes, plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the date of redemption. We may also redeem some or all of the senior notes on or after April 1, 2016, at the redemption prices (expressed as percentages of principal) set forth below, plus accrued and unpaid interest, if any, on the notes redeemed to the applicable redemption date.

        The revolving credit facility has a maturity date of March 28, 2018. At March 31, 2014, and December 31, 2013, there were no amounts outstanding under the revolving credit facility.

        The senior notes rank equally in right of payment with all of our existing and future senior indebtedness. The notes are guaranteed on a senior unsecured basis by our wholly-owned subsidiary PL Propylene. The full and unconditional guarantee ranks equally with all of the existing and future senior indebtedness of our guarantor subsidiaries. PL Propylene and PetroLogistics Finance Corp. are our only subsidiaries. Finance Corp. has no material assets and does not conduct any operations. The Partnership has no independent assets or operations, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended. The senior notes and the guarantee are effectively subordinated to all of our and our guarantor subsidiaries' existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. In addition, the senior notes are structurally subordinated to all future indebtedness and other liabilities of any of our subsidiaries that are not issuers or guarantors of the senior notes.

Loss on Extinguishment of Debt

        When we entered into the 2013 credit facilities, we recognized a loss on extinguishment of debt of approximately $20.4 million in our consolidated statements of comprehensive income for the three month period ended March 31, 2013. This loss on extinguishment resulted from the write off of approximately $7.7 million of unamortized deferred financing costs associated with the prior credit facilities. We also wrote off the unamortized original issue discount associated with the 2012 credit facilities in the amount of approximately $5.8 million. In addition, we paid a call premium of approximately $6.9 million for the prepayment of the term loan.

6. Long-Term Incentive Plan

2012 Long-Term Incentive Plan

        Our General Partner adopted The Long-Term Incentive Plan in May 2012. The Long-Term Incentive Plan is intended to promote our interests by providing incentive compensation, based on our common units, to employees, consultants and directors and to encourage superior performance. The Long-Term Incentive Plan provides for grants of restricted units, phantom units, unit awards and other unit-based awards up to a plan maximum of 5,882,352 common units.

Unit-based Awards

        A unit-based award under the Long-Term Incentive Plan is a phantom unit whose terms and conditions are set by the Long-Term Incentive Plan administrative committee and that generally vests over a period of time and during that time is subject to forfeiture. Our unit-based awards to employees will generally vest over a three-year period either annually from the date of grant or upon the third anniversary of the grant date, provided the recipient has continuously provided services to us, our General Partner, or any other of our affiliates. Unit awards to members of our General Partner's board of directors vest upon the first anniversary of the date of grant.

        Certain unit-based awards are eligible for DERs. Absent any restrictions on the DERs in an award agreement, we will pay DERs to the holder of the award without restriction at approximately the same time as we pay quarterly cash distributions to our common unitholders.

        During the three months ended March 31, 2014, we recognized total equity-based compensation expense of approximately $1.3 million related to the unit-based awards ($0.6 million as cost of sales and $0.7 million as general and administrative expense).

        During the three months ended March 31, 2013, we recognized total equity-based compensation expense of approximately $1.1 million related to the unit-based awards ($0.5 million as cost of sales and $0.6 million as general and administrative expense).

        The following table presents activity related to our Long-Term Incentive Plan awards, including those granted to employees during the three months ended March 31, 2014:

7. Related Party and Affiliate Transactions

Services Agreement with PetroLogistics GP LLC

        Our General Partner provides certain operational, managerial and general administrative services to us. All employees of PL Propylene and PetroLogistics LLC are employees of our General Partner. We reimburse the General Partner for all direct and indirect expenses the General Partner incurs or payments the General Partner makes on our behalf including, without limitation, salary, bonus, incentive cash compensation and employee benefits. During the three months ended March 31, 2014 and 2013, we incurred fees of $8.4 million and $7.1 million, respectively, under the services agreement with our General Partner. The amounts we pay the General Partner for these services are reported in the consolidated statements of comprehensive income in the line item to which the expense relates.

7. Related Party and Affiliate Transactions (Continued)

        During the three months ended March 31, 2014 and 2013, we utilized the services of a company owned by Lindsay Goldberg in the amounts of approximately $0.6 million and $0.4 million, respectively, in connection with facility maintenance activities which is reported in costs of sales.

8. Concentration of Risk

Credit Risk Due to Industry and Customer Concentrations

        All of our revenues are derived from companies in the petrochemical industry, and our principal market is the Texas Gulf Coast region. This concentration could affect our overall exposure to credit risk since these customers may be affected by similar economic or other conditions. Generally, we do not require collateral for our accounts receivable; however, we attempt to negotiate prepayment agreements with customers that are deemed to be credit risks in order to minimize our potential exposure to any defaults.

        The following table presents the concentration of total sales to our largest customers:

 
  Three Months
Ended
March 31,
 
 
  2014   2013  

The Dow Chemical Company ("Dow")

    43 %   42 %

Total Petrochemicals & Refining USA, Inc. ("Total")

    24 %   21 %

INEOS Olefins and Polymers USA ("INEOS")

    21 %   21 %

Others (less than 10% individually)

    12 %   16 %
           

Total sales

    100 %   100 %
           
           

        We have entered into market-based sales contracts with our propylene customers to provide minimum and maximum annual quantities. (See Note 9). These maximum quantities comprise the substantial majority of our facility's anticipated annual production of propylene. This concentration in the volume of business transacted with a limited number of customers subjects us to substantial risks. The loss of any of the above-named customers without replacement on comparable terms could adversely affect our business, results of operations and financial condition. If we were to lose one or more of our current customers, we would seek to engage in sales transactions with other petrochemical companies on either a long-term contract basis or in the spot market, although there is no assurance we would be able to do so.

        We have entered into long-term market-based contracts for the purchase of propane, our sole feedstock, as well as nitrogen and natural gas. There is only one supplier in each of these contracts. Interruptions in or limitations on volumes provided under these contracts subject us to the risk that we would be unable to meet our production requirements if we were unable to locate and procure replacement volumes from alternate sources.

Legal Matters

        We are routinely involved in various legal matters arising from the normal course of business for which no provision has been made in the financial statements. While the outcome of these proceedings cannot be predicted with certainty, we believe that these proceedings, when resolved, will not have a material adverse effect on our results of operations financial position or liquidity.

        In March 2014, we received notice of a lawsuit filed against us for liability involving personal injuries sustained in February 2014 by a contractor's employee working at our facility. Our third-party contracts contain indemnification clauses for incidents of this nature, including an obligation of the contractor to indemnify and defend us with respect to the applicable lawsuit. We also carry general liability insurance, subject to a deductible. We do not expect the cost of a settlement or eventual judgment, if any, to be material to our financial position or results of operations.

10. Subsequent Events

        On April 23, 2014, our General Partner approved a distribution of $0.37 per common unit to common unitholders of record as of May 5, 2014, which will be paid on May 14, 2014.

Overview

        We currently own and operate the only U.S. propane dehydrogenation (or "PDH") facility (or "our facility") producing propylene from propane. Propylene is one of the basic building blocks for petrochemicals that is utilized in the production of a variety of end uses including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. We are the only independent, dedicated "on-purpose" propylene producer in North America. We are strategically located in the vicinity of the Houston Ship Channel, which is situated within the

F-19


largest propylene consumption region in North America. We also have access to the leading global fractionation and storage hub for propane located in Mt. Belvieu, Texas. Our location provides us with excellent access and connectivity to both customers and feedstock suppliers.

        We currently have multi-year contracts for the sale of our propylene with The Dow Chemical Company ("Dow"), Total Petrochemicals & Refining USA, Inc. ("Total"), BASF Corporation ("BASF') and INEOS Olefins and Polymers USA ("INEOS") that expire between 2016 and 2018 and a one-year contract with LyondellBasell Industries N.V. ("LyondellBasell") that ends in December 2014. Our customer contracts provide for minimum and maximum offtake volumes, with the minimum customer-contracted volumes representing approximately 75% of our current facility capacity and the maximum reflecting approximately 96% of our current facility capacity. Each of our customer contracts contain pricing terms based upon market rates. In addition to our contracted sales, we have made and will continue to make additional propylene sales on a spot basis. Also, if necessary, we may purchase propylene in order to meet short-term customer obligations.

        Propylene comprised approximately 97% and 98% of our sales during the three months ended March 31, 2014 and 2013, respectively. In addition to propylene, we also produce commercial quantities of hydrogen and C4 mix/C5+ streams.

        Our historical results of operations and cash flows may not be indicative of results of operations and cash flows to be expected in the future, principally for the following reasons:

F-20


F-21


Factors Affecting Results

        We believe key factors that influence our business and impact our operating results are (1) the propane-to-propylene spread, (2) our facility's capacity utilization and (3) customer sales.

Propane-to-Propylene Spread

        The price spread between propane, our sole feedstock, and propylene, our primary product, largely determines our gross margin and is the key driver of our profitability.

        Propylene sales constitute substantially all of our sales. Propylene is a commodity, and its price can be cyclical and highly volatile. The price of propylene depends on a number of factors, including general economic conditions, cyclical trends in end-user markets and supply and demand imbalances. The customers under our propylene sales contracts (Dow, Total, BASF, INEOS and LyondellBasell) each pay market-based prices for propylene, and a significant decrease in propylene prices would have a material adverse effect on revenue generated from these customers. In addition, a decrease in the price of propylene would result in decreased revenue from any sales of propylene on the spot market. Assuming annual sales of 1.3 billion pounds, a one cent increase (decrease) in the propane-to-propylene spread results in an annual increase (decrease) of $13 million in gross margin and approximately $0.09 per unit in distributable cash flow on an annual basis.

        Propane is the sole feedstock in our production process, and the cost of propane represents a substantial portion of our cost of sales. Enterprise Products Operating LLC (together with its affiliates, "Enterprise") supplies 100% of our required propane feedstock volume under a multi-year contract at market-based prices, which prices are subject to fluctuations in response to changes in supply, demand, market uncertainties and a variety of additional factors beyond our control. See "Item 3. Quantitative and Qualitative Disclosures About Market Risk."

        Our facility had an original nameplate capacity of 1.2 billion pounds of propylene annually. However, based on plant optimization and operating improvements, our facility currently has an annual production capacity of approximately 1.4 billion pounds. Actual annual production will vary based on a number of factors, including the amount of downtime for planned and unplanned maintenance on the facility and the overall efficiency of the facility. Any significant planned or unplanned downtime may affect not only production, and therefore sales, but also capital expenditures and direct operating expenses, primarily maintenance expenses and fuel and utilities.

        Our results are affected by customer demand. When propylene production exceeds customer nominations, we build inventory for future sales or seek opportunities to sell the excess production on the spot market. When customer nominations exceed our propylene production and we elect not to declare force majeure, we satisfy the shortfall out of inventory or purchase propylene on the spot market. In certain circumstances, a customer will nominate more than it will actually take in a month. In those situations, we deliver the excess product into storage, defer the sales recognition until the customer takes actual delivery and recognize an exchange inventory balance with the customer. We invoice customers for quantities delivered to the customer and for quantities delivered into storage on the customer's behalf and are paid by the customer based on its actual monthly nominations. As a result of the foregoing, customer billings in one month may not result in sales until a future month.

F-22


How We Evaluate Our Performance

        In addition to utilizing the key factors affecting our operating results described above to evaluate our performance, our management uses certain additional financial and operational measures as well. These measures include Adjusted EBITDA and health, safety and environmental performance.

Adjusted EBITDA

        We define Adjusted EBITDA as net income plus interest expense and amortization of deferred financing costs (including loss on extinguishment of debt), income tax expense, depreciation, amortization and accretion, equity-based compensation expense, unrealized gain (loss) on derivatives and, effective May 9, 2012 through April 29, 2013, realized gains and losses on the propane swaps. Adjusted EBITDA is a non-U.S. GAAP financial measure that may be used by our management and by external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, to assess:

        We view Adjusted EBITDA as an important indicator of cash flow generation. Adjusted EBITDA is principally affected by our sales volumes, the propane-to-propylene spread, capacity utilization, propane-to-propylene conversion factors and, to a lesser extent, the prices of natural gas and our by-products. Other than the cost of propane and natural gas, production-related expenses generally remain stable across broad ranges of throughput volumes, but can fluctuate significantly depending on the planned and unplanned maintenance performed during a specific period. Our Adjusted EBITDA and available cash may not always correlate to each other.

        Adjusted EBITDA should not be considered an alternative to net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with U.S. GAAP. Our Adjusted EBITDA may not be comparable to Adjusted EBITDA or similarly titled measures of other entities, as other entities may not calculate Adjusted EBITDA in the same manner as we do. Our management compensates for the limitations of Adjusted EBITDA as an analytical tool by reviewing the comparable U.S. GAAP measures, understanding the differences between the measures and incorporating this knowledge into management's decision-making processes. Adjusted EBITDA should not be viewed as indicative of the actual amount of cash we have available for distributions or that we plan to distribute for a given period.

Effective May 9, 2012, pursuant to the omnibus agreement, to the extent that we made payments for realized losses under our propane swaps, PL Manufacturing LLC and the owners of 100% of the issued and outstanding equity interests of PL Manufacturing (the "PL Manufacturing Members"), through our General Partner, were responsible for making quarterly capital contributions to us in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter resulting in a capital contribution to us and a zero net effect on cash and partners' capital. The amount of realized loss on derivatives shown as an adjustment for EBITDA represents the amount received or to be received from PL Manufacturing and the PL Manufacturing Members. See discussion of the omnibus agreement in Note 2 to our consolidated financial statements included elsewhere in this report.

Health, Safety and Environmental Performance

        We consider our ability to manage our facility and customer needs in a safe and reliable manner to be a critical factor in assessing our performance. Accordingly, we have an extensive training program and set annual goals on achieving operating performance and safety measures that assure the reliable operation of our facility and a safe working environment for our employees. Further, we closely monitor all environmental metrics to assure compliance with all regulatory requirements and that we operate in an environmentally responsible manner.

Results of Operations

        The period-to-period comparisons of our results of operations have been prepared using the historical periods included in our consolidated financial statements. In order to effectively review and assess our historical financial information below, we have also included a description of the components of the various financial statement line items.

        Sales.    Sales are comprised of propylene sales and by-product sales, which include hydrogen and C4 mix/C5+ streams.

        Cost of Sales.    Cost of sales represents the costs of propylene and by-products sold. These costs include the cost of propane, fuel and utilities used in the propylene production process, as well as direct operating expenses and insurance and property tax expenses associated with our facility. Direct

F-24


operating expenses include all direct and indirect labor at our facility, materials, supplies, and other expenses associated with the operation and maintenance of the facility. Depreciation, amortization and accretion expenses, exclusive of amortization of deferred financing fees, as well as equity-based compensation expense for awards granted to operating personnel are also included within cost of sales. During periods in which our facility operates below normal capacity, we record charges to cost of sales to reflect unabsorbed fixed overhead costs.

        General and Administrative Expense.    General and administrative expense includes salary and benefits costs for executive management, accounting and information technology personnel, as well as legal, audit, tax and other professional service costs and charges for equity-based compensation expense. Also included in general and administrative expense is development expense which includes preliminary engineering and design work for capital projects which do not qualify for capitalization under GAAP.

        Loss on Derivatives, net.    Our propane swaps were recorded as derivative assets and liabilities, as applicable, at fair value on our consolidated balance sheets. Our derivative contracts did not qualify for hedge accounting treatment. Consequently, the associated realized and unrealized gains and losses were recorded as current expense or income in the consolidated statements of comprehensive income. Unrealized gains or losses on derivatives represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows until settlement occurs. For further discussion see "—Liquidity and Capital Resources."

        Interest Expense, net.    Interest expense, net, includes expense incurred on outstanding debt balances, the amortization of loan discount and deferred financing fees and loan commitment expenses under our credit facilities. Loan commitment expense is comprised of the fees assessed on the unutilized portion of our credit facility. Interest income results from earnings on available cash balances and is offset against interest expense.

        Income Tax Expense.    As an entity operating in the State of Texas, we are subject to the Texas Margin Tax. This tax represents a tax on gross margin, as adjusted, and is reported as income tax expense in the accompanying statements of comprehensive income.

        Sales.    For the three months ended March 31, 2014 and 2013, we recognized sales on approximately 310.7 million and 288.7 million pounds of propylene, respectively. Product output for the first quarter of 2014 totaled approximately 315.5 million pounds of propylene compared to 298.9 million pounds of propylene produced during the first quarter of 2013, which represents an increase in production of approximately 6%. The increase in sales resulted primarily from the increase in propylene production. The average polymer grade contract benchmark propylene price in the three months ended March 31, 2014, was 73.3 cents per pound compared to an average of 75 cents per pound for the three months ended March 31, 2013, a decrease of 1.7 cents per pound or 2%. This decrease in the average contract benchmark price of propylene partially offset the increase in sales that resulted from the higher production.

        Cost of sales was $161.6 million, or approximately 73% of sales for the three months ended March 31, 2014, compared to $114.1 million, or approximately 55% of sales, for the same period during 2013, which represents an increase of $47.5 million. The primary component of cost of sales is the propane feedstock, which represented approximately 76% and 70% of total production costs for the three months ended March 31, 2014 and 2013, respectively. An increase in propane pricing from an average of $0.86 per gallon in 2013 to $1.30 per gallon in 2014 combined with increased propylene production in the first quarter of 2014 compared to the same period in 2013 resulted in an increase in propane expense of $45.8 million. In the first quarter of 2013, we purchased propylene from third parties for $14.5 million in anticipation of our October 2013 triennial turnaround.

        General and Administrative Expense.    General and administrative expense was $4.7 million for the three months ended March 31, 2014, compared to $5.4 million for the three months ended March 31, 2013, which represents a decrease of $0.7 million. The higher general and administrative expense for the three months ended March 31, 2013, is primarily attributable to an additional $0.6 million in development expense related to potential expansion and profit enhancement projects at our facility incurred during that period.

        Loss on Derivatives, net.    The net loss on derivatives represents the net realized and unrealized gains and losses on the propane swaps. We recorded the propane swaps at fair value using observable inputs based on market data obtained from independent sources. Because the propane swaps did not qualify for hedge accounting treatment, the mark-to market adjustments were reported in our consolidated statements of comprehensive income. We incurred no gains or losses associated with propane swaps during the three months ended March 31, 2014, as all swap positions were terminated during the second quarter of 2013. The net loss on derivatives of $3.7 million for the three months

F-26


ended March 31, 2013, was comprised of mark-to market unrealized gains of $18.4 million and realized losses of $22.1 million which were recognized at each monthly settlement date.

        Interest Expense, net.    Interest expense of $5.7 million was incurred for the three months ended March 31, 2014, on an average daily debt balance of $366.3 million. For the three months ended March 31, 2013, we incurred $6.1 million in interest expense on an average debt balance of $348.7 million. Total interest expense for the three months ended March 31, 2014 and 2013, includes $0.5 million and $0.6 million of amortized deferred financing costs, respectively. Also included in total interest expense for the three months ended March 31, 2013 was $0.3 million of loan discount amortization. Loan commitment expense was $0.2 million for the three months ended March 31, 2014 and 2013.

        Loss on Extinguishment of Debt.    We recognized a loss on extinguishment of debt of $20.4 million for the three months ended March 31, 2013, as a result of refinancing our term loan and amending and extending our revolving credit facility in March 2013 at which time we wrote off approximately $7.7 million of unamortized deferred financing costs associated with the 2012 credit facilities and $5.8 million of unamortized original issue discount associated with the 2012 credit facilities. We also paid a $6.9 million call premium for the prepayment of the term loan in March 2013.

        Income Tax Expense.    Income tax expense was $0.6 million for the three months ended March 31, 2014, compared to $0.8 million for the three months ended March 31, 2013, in each case, resulting from income taxes incurred on gross margin with the State of Texas.

Critical Accounting Policies

        The preparation of our financial statements in accordance with U.S. GAAP requires that management make estimates and assumptions affecting the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting period. There were no changes in our critical accounting policies for the period covered by this report.

Liquidity and Capital Resources

        Our principal source of liquidity is cash flows from operations. Our principal uses of cash have been and are expected to be for working capital, distributions, capital expenditures and funding our debt service obligations. We believe that our cash from operations will be adequate to satisfy commercial commitments for the next twelve months and that cash flow together with borrowings under our revolving credit facility will be adequate to fund our planned capital expenditures and working capital needs.

        Our ability to make distributions, to make payments on and to refinance our indebtedness, to fund planned capital expenditures and to satisfy our other capital and commercial commitments will depend on our ability to generate cash flows in the future. This, to a certain extent, is subject to the prevailing propane-to-propylene spread, natural gas prices and general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. Our business may not generate sufficient cash flows from operations, and future borrowings may not be available to us under our credit facilities in amounts sufficient to enable us to make quarterly distributions, finance necessary capital expenditures, service our indebtedness or fund our other liquidity needs. We may seek to sell assets or issue debt securities or additional equity securities to fund our liquidity needs but may not be able to do so. We may also need to refinance all or a portion of our indebtedness on or before maturity. We may not be able to refinance any of our indebtedness on commercially reasonable terms or at all.

F-27


Capital Spending

        During the three months ended March 31, 2014, we incurred capital expenditures of $8.6 million primarily for the replacement of two heat exchangers, backup spare parts and various upgrades and profit improvement projects. During the three months ended March 31, 2013, we incurred capital expenditures of $15.8 million of which $7.5 million represented replacement catalyst for the October 2013 triennial turnaround.

        Our future capital spending will be determined by management and approved by the board of directors of our General Partner. We currently plan to incur capital expenditures of approximately $40.8 million during 2014. Included in this amount is approximately $10.0 million of maintenance capital expenditures and $30.8 million for profit enhancement projects.

        Our estimated capital expenditures and planned major maintenance costs are subject to change due to unforeseen circumstances and unanticipated increases in the cost, scope and completion time of each respective project. For example, we may experience increases in labor or equipment costs necessary to comply with government regulations or to complete projects that sustain or improve the profitability of our facility.

        Maintenance capital expenditures and future planned turnaround expenses will be funded using cash flow from operations. Should we identify opportunities for other capital expenditures (including acquisitions and plant expansion capital expenditures), such expenditures may be funded using cash flow from operations or, if significant, will be funded by issuances of debt or equity. We have elected to reserve amounts in the period(s) preceding planned major maintenance projects in order to fund the estimated capital costs in the period in which the project(s) are expected to occur. The actual costs associated with planned major maintenance projects may, however, differ from the estimated amounts reserved.

        On March 28, 2013, we and our wholly-owned finance subsidiary, PetroLogistics Finance Corp., co-issued jointly and severally $365.0 million of senior unsecured notes due 2020 (the "senior notes"), and we entered into an amended and restated credit agreement which expanded our revolving credit facility (together with the senior notes, the "2013 credit facilities") from $120 million to $170 million with Morgan Stanley Senior Funding, Inc. (the "Agent"), and the lender parties thereto. We used the net proceeds from the issuance of the senior notes, after underwriting fees of $7.3 million, to (1) repay all borrowings outstanding under our term loan facility in the amount of approximately $347.4 million, (2) pay approximately $6.9 million for the call premium and costs associated with the cancellation of our term loan facility and (3) pay $3.0 million in commitment fees and approximately $0.4 million in transaction fees. In addition, we paid approximately $1.3 million in third party transaction costs from cash on hand. The senior notes were issued at the par value of $365 million, and are reported as long-term debt in our consolidated balance sheet at March 31, 2014.

        The indenture governing the senior notes and our amended and restated credit agreement contain certain restrictive financial covenants including limitations on our ability to incur additional debt and the requirement under the terms of our revolver to maintain a total senior secured leverage ratio, as defined, no greater than 2.0 to 1.0, but as to the senior secured leverage ratio test only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2013, the aggregate amounts outstanding under the revolving credit facility exceeds $120 million. At March 31, 2014, there were no outstanding borrowings under the revolving credit facility, and our borrowing capacity was $170 million.

        Interest Rate and Fees.    The senior notes bear interest at a fixed rate of 6.25% per annum, payable on April 1 and October 1. The revolving credit facility bears interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the revolving credit facility

F-28


ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greatest of the prime rate in effect and the federal funds effective rate in effect plus 1/2 of 1.0%. The revolving credit facility also contains a facility commitment fee at a rate of 0.50% per annum based on the daily unused amount of the commitment amount of $170 million payable in arrears on the last day of March, June, September and December of each year.

        Amortization and Final Maturity.    The senior notes have a maturity date of April 1, 2020. Prior to April 1, 2016, we may redeem all or part of the senior notes at a redemption price equal to the sum of 100% of the principal amount of the senior notes, plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the date of redemption. We may also redeem some or all of the senior notes on or after April 1, 2016, at a premium (expressed as a percentage of principal) plus accrued and unpaid interest, if any, on the notes redeemed to the applicable redemption date. The revolving credit facility has a maturity date of March 28, 2018.

        Guarantees.    The senior notes rank equally in right of payment with all of our existing and future senior indebtedness. The notes are guaranteed on a senior unsecured basis by PL Propylene. The full and unconditional guarantee ranks equally with all of the existing and future senior indebtedness of our guarantor subsidiaries. PL Propylene and PetroLogistics Finance Corp. are our only subsidiaries. We have no independent assets or operations, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended. The senior notes and the guarantee are effectively subordinated to all of our and our guarantor subsidiaries' existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. In addition, the senior notes are structurally subordinated to all future indebtedness and other liabilities of any of our subsidiaries that are not issuers or guarantors of the senior notes.

        In connection with our refinancing, we wrote off approximately $20.4 million of unamortized deferred financing costs, unamortized issue discount, and retirement premium associated with the prior credit facility. The write-off of these costs is reflected as a loss on extinguishment of debt in our consolidated statements of comprehensive income for the three months ended March 31, 2013. At March 31, 2014, we had $170.0 million available under the new revolving credit facility.

        We entered into an interest rate protection agreement in July 2012 pursuant to which we capped the three month LIBOR rate at 2.0% for up to $115.5 million on our term loan. The agreement terminated on March 27, 2014.

        Net cash provided by operating activities for the three months ended March 31, 2014, was $48.6 million. This positive cash flow from operating activities resulted from net income of $46.7 million which reflects certain non-cash items for equity-based compensation, depreciation, amortization and accretion, amortization of deferred financing costs and deferred income taxes totaling $14.3 million. Cash flows from operations was reduced by a $12.4 million net increase in working capital driven by a $21.4 million decrease in accounts payable due primarily to a decrease in our liability for purchased propane from December 31, 2013 to March 31, 2014.

        Net cash provided by operating activities for the three months ended March 31, 2013, was $28.4 million. This positive cash flow from operating activities resulted from net income of $57.1 million which reflects certain non-cash items for unrealized gains on derivatives, equity-based compensation, depreciation, amortization and accretion, amortization of deferred financing costs, loss on extinguishment of debt and deferred income taxes totaling $6.9 million net. Cash flows from

F-29


operations was reduced by a $35.6 million net increase in working capital driven by a $15.4 million increase in accounts receivable attributed to the higher propylene price in March 2013 and a $14.2 million inventory increase for propylene stored in advance of our 2013 turnaround.

        Net cash used in investing activities for the three months ended March 31, 2014 and 2013, was $8.6 million and $15.8 million, respectively, related to capital expenditures for our facility.

        Net cash used in financing activities for the three months ended March 31, 2014, was $42.0 million, which resulted from cash distributions to unit holders totaling $42.0 million for the period.

        Net cash used in financing activities for the three months ended March 31, 2013, was $1.6 million. Our cash flows used in financing activities resulted from net borrowings of approximately $7.0 million offset by net cash distributions totaling $7.3 million. Additionally, we had cash outflows for deferred financing costs of $1.3 million related to the 2013 credit facilities.

        We do not have any material "off-balance sheet arrangements" as such term is defined within the rules and regulations of the SEC.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

        Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in financial and commodity market prices and rates. Given that our business is currently based entirely in the U.S., we are not directly exposed to foreign currency exchange rate risk.

Commodity Price Risk

        Propylene sales constitute substantially all of our sales. Propylene is a commodity, and its price can be cyclical and highly volatile. The price of propylene depends on a number of factors, including general economic conditions, cyclical trends in end-user markets and supply and demand balances. The customers under our propylene sales contracts (Dow, Total, BASF, INEOS and LyondellBasell) each pay market-based prices for propylene, and a significant decrease in propylene prices would have a material adverse effect on revenue generated from these customers.

        Propane is the sole feedstock in our production process, and the cost of propane represents a substantial portion of our cost of sales. The price of propane is correlated to the price of crude oil and is influenced by the price of natural gas. The prices for crude oil and natural gas are cyclical and volatile, and as a result, the price of propane can be cyclical and volatile. The propane export market may also impact the price of propane. According to the U.S. Energy Information Administration, propane exports increased significantly during 2013.

        If propane costs increase, the market price of propylene may not rise correspondingly or at all. Timing differences between propane prices, which may change daily, and the market price of propylene, which is set monthly, may narrow the propane-to-propylene spread and thus reduce our cash flow, which reduction could be material. Assuming annual sales of 1.3 billion pounds, a one cent increase (decrease) in the propane-to-propylene spread results in an annual increase (decrease) of $13 million in gross margin and approximately $0.09 per unit in distributable cash flow on an annual basis. We obtain all of the propane we need from a single supplier through its propane pipeline system, which is connected to the natural gas liquids and refined products storage hub at Mt. Belvieu. The price that we pay our supplier for propane fluctuates based on market prices. Propane prices could increase significantly in the future. In addition, following the expiration of our current propane supply contract, the price of storage and transportation of propane to our site is subject to change and could adversely impact our financial results.

F-30


        The raw materials we consume, such as natural gas, electricity and nitrogen, are generally commodity products that are readily available at market prices. We generally enter into supply agreements with particular suppliers, but disruptions of existing supply arrangements could substantially impact our profitability. If certain of our suppliers are unable to meet their obligations under present supply agreements, we may be forced to pay higher prices to obtain the necessary materials from other sources. In addition, if any of the raw materials that we use become unavailable within the geographic area from which they are now sourced, then we may not be able to obtain suitable or cost effective substitutes. Any interruption in the supply of raw materials will increase our costs or decrease our sales, which will reduce our cash flow.

        An increase in the price of natural gas could narrow the propane-to-propylene spread in two ways, each adversely affecting our gross margins. First, a significant increase in natural gas prices could be accompanied by an increase in the price of NGLs such as ethane. An increase in ethane prices could cause ethylene producers to favor the use of naphtha as a feedstock. Because the use of naphtha as a feedstock in the ethylene production process results in significantly more propylene as co-product than ethane, the result would be an increase in propylene production by ethylene plants. The increased supply of propylene would in turn exert downward pressure on the price of propylene, adversely affecting the price we obtain for the propylene we produce, both in the spot market and pursuant to our customer contracts, which are market-based.

        Second, an increase in the price of natural gas may be accompanied by an increase in the price of propane, as the majority of propane is derived from natural gas production, thereby further narrowing the propane-to-propylene spread and reducing our gross margins.

        Our supply agreements typically provide for market-based pricing and provide us no protection against price volatility. If the costs of any of our feedstock or raw materials rise, the market price of propylene may not rise correspondingly or at all. Timing differences between our feedstock or raw material prices, which may change daily, and the market price of propylene, which is set monthly, may have a negative effect on our cash flow. Any cost increase could have a material adverse effect on our business, results of operations, financial condition and liquidity.

        Commencing October 2011 through March 2012, we entered into propane swaps with the intent of reducing volatility in our cash flows due to fluctuations in the price of propane, our sole feedstock. Under the terms of the propane swaps, for a portion of our propane consumption, we locked in the price of propane as a fixed percentage of the price of Brent crude oil (the "contractual percentage"). Beginning in January 2012, and at the conclusion of each subsequent month through the May 2013 cancellation date, we performed a calculation to determine the average actual price of propane for that month as a percentage of the average actual price of Brent crude oil for that month (the "actual percentage"). If the actual percentage exceeded the contractual percentage under the propane swaps, we were owed a sum by the propane swaps counterparty. If the contractual percentage exceeded the actual percentage under the propane swaps, we owed a sum to the propane swaps counterparty.

        Upon the closing of the IPO, we entered into the omnibus agreement and the pledge agreement, pursuant to which PL Manufacturing and the PL Manufacturing Members, through our General Partner, assumed all of our benefits and obligations under the propane swaps. Under the omnibus agreement and the pledge agreement, any amounts received by us under the propane swaps were to be distributed, through our General Partner, to the PL Manufacturing Members, and any amounts that we were required to pay under the propane swaps were contributed back to us as a capital contribution by the PL Manufacturing Members. On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. During the three months ended March 31, 2013, we recorded capital contributions from PL Manufacturing and the PL Manufacturing Members of $22.1 million for reimbursement of realized losses incurred on the propane swaps for the first quarter of 2013. These contributions were funded through reductions in the

F-31


distributions we paid in May 2013 to PL Manufacturing and the PL Manufacturing Members on the common units they own.

        In the future, management may elect to use derivative commodity instruments consistent with our overall business objectives to avoid unnecessary risk and to limit, to the extent practical, risks associated with certain of our operating activities.

Interest Rate Risk

        Our senior notes bear interest at a fixed interest rate while our revolving credit facility has a variable interest rate based on an underlying base rate plus an applicable margin. The applicable margin ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greater of the prime rate in effect and the federal funds effective rate in effect plus 1/2 of 1%. At March 31, 2014, we had no outstanding borrowings under our revolving credit facility.

        Our management will continue to monitor whether financial derivatives become available which could effectively hedge identified risks. In the future, management may elect to use derivative financial instruments consistent with our overall business objectives to avoid unnecessary risk and to limit, to the extent practical, risks associated with our operating activities.

Item 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

        We have established disclosure controls and procedures to ensure that material information relating to the Partnership and its consolidated subsidiaries is made known to the officers of our General Partner who certify our financial reports and the Board of Directors.

        Our Principal Executive Officers, David Lumpkins and Nathan Ticatch, and our Principal Financial Officer, Sharon Spurlin, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the quarterly period ended March 31, 2014 (the "Evaluation Date"). Based on this evaluation, they believe that as of the Evaluation Date our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms; and (ii) is accumulated and communicated to our management, including the Principal Executive Officers and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

        There has not been any change in our internal control over financial reporting that occurred during our quarterly period ended March 31, 2014, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.


PART II—OTHER INFORMATION

Item 1.    LEGAL PROCEEDINGS.

        We are, and will continue to be, subject to litigation from time to time in the ordinary course of our business. On March 4, 2014, we received notice of a lawsuit filed on behalf of Anthony Garza against us and one other party in the District Court of Harris County, Texas, 151st Judicial District, at case number 2014-09650, for liability involving personal injuries sustained in February 2014 by Mr. Garza, an employee of one or our contractors, while working at our facility. The plaintiff makes a

number of allegations, including a claim that the defendants breached a duty of care owing to the plaintiff. Our contract with the contractor contains an obligation on the contractor to indemnify and defend us with respect to matters of this nature. We also carry general liability insurance, subject to a deductible. We do not expect the cost of a settlement or eventual judgment, if any, to be material to our financial position or results of operations.

Item 1A.    RISK FACTORS

        In addition to the other information set forth in this Form 10-Q, you should carefully consider the factors discussed under the heading "Risk Factors" in our annual report on Form 10-K for the year ended December 31, 2013, as filed with the SEC on March 7, 2014, which could materially affect our business, financial condition, or future results. The risks described in the annual report are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or operating results.
