NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

To Be Held May 4, 2006

TO OUR STOCKHOLDERS:

      Notice is hereby given that the annual meeting of the stockholders of Halozyme Therapeutics, Inc., a Nevada corporation, will be held on May 4, 2006, at 9:00 a.m. local time, in the Coronado room at the San Diego Marriott Hotel located at 11966 El Camino Real, San Diego 92130, for the following purposes:

San Diego, California

PROXY STATEMENT FOR ANNUAL MEETING OF STOCKHOLDERS

      The accompanying proxy is solicited by the Board of Directors of Halozyme Therapeutics, Inc., a Nevada corporation, for use at its annual meeting of stockholders to be held on May 4, 2006, or any adjournment or postponement thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Stockholders. This Proxy Statement and the enclosed proxy are being mailed to stockholders on or about March      , 2006.

HISTORICAL NOTE

      Halozyme Therapeutics, Inc. is the product of the March 11, 2004, merger between DeliaTroph Pharmaceuticals, Inc. (“DeliaTroph”), a private biopharmaceutical company, and Global Yacht Services, Inc. (“Global”), a publicly traded yacht chartering and sales company. In the merger, Global issued Common Stock to the former shareholders of DeliaTroph in exchange for all of their interests in DeliaTroph. Although Global conducted limited operations prior to the merger and was the parent entity of DeliaTroph following the merger, the former shareholders of DeliaTroph held approximately 90% of the outstanding voting interest in the combined enterprise immediately after the merger. DeliaTroph’s management and Board of Directors assumed operational control of Global immediately following the merger and Global changed its name to Halozyme Therapeutics, Inc. The historical operations of Global ceased in connection with the merger and the historical operations of DeliaTroph continued. The merger has been treated as a re-capitalization of DeliaTroph for accounting purposes and the historical and financial information presented here and in our Annual Report reflects the pre-merger activities of DeliaTroph and does not include information relating to the activities of Global prior to the merger unless otherwise indicated.

SOLICITATION AND VOTING

      Voting Securities. Only stockholders of record as of the close of business on March 31, 2006, will be entitled to vote at the meeting and any adjournment thereof. As of that time, we had approximately                      shares of Common Stock outstanding, all of which are entitled to vote with respect to all matters to be acted upon at the annual meeting. Each stockholder of record as of that date is entitled to one vote for each share of Common Stock held by him or her. Our Bylaws provide that a majority of all of the shares of the stock entitled to vote, whether present in person or represented by proxy, shall constitute a quorum for the transaction of business at the meeting. Votes for and against, abstentions and “broker non-votes” will each be counted as present for purposes of determining the presence of a quorum.

      Broker Non-Votes. A broker non-vote occurs when a broker submits a proxy card with respect to shares held in a fiduciary capacity (typically referred to as being held in “street name”) but declines to vote on a particular matter because the broker has not received voting instructions from the beneficial owner. Under the rules that govern brokers who are voting with respect to shares held in street name, brokers have the discretion to vote such shares on routine matters, but not on non-routine matters. Routine matters include the election of directors, increases in authorized common stock for general corporate purposes and ratification of auditors. Non-routine matters include adoptions of, and amendments to, stock plans.

      Solicitation of Proxies. We will bear the entire cost of soliciting proxies. In addition to soliciting stockholders by mail through our employees, we will request banks, brokers and other custodians, nominees and fiduciaries to solicit customers for whom they hold our stock and will reimburse them for their reasonable, out-of-pocket costs. We may use the services of our officers, directors and others to solicit proxies, personally or by telephone, without additional compensation. In addition, we may retain a proxy solicitation firm or other third party to assist us in collecting or soliciting proxies from our stockholders, although we do not currently plan on retaining such a proxy solicitor.

      Voting of Proxies. All valid proxies received before the meeting will be exercised. All shares represented by a proxy will be voted, and where a proxy specifies a stockholder’s choice with respect to any matter to be acted upon, the shares will be voted in accordance with that specification. If no choice is indicated on the proxy, the shares will be voted in favor of the proposal. A stockholder giving a proxy has the power to revoke his or her proxy at any time before it is exercised by delivering to the Secretary of Halozyme a written instrument revoking the proxy or a duly executed proxy with a later date, or by attending the meeting and voting in person.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

      We have a classified Board of Directors that consists of two Class I directors, two Class II directors and two Class III directors. Our directors are elected for a term of three years, with one class of directors up for election every year. In connection with the 2006 annual meeting of stockholders we will be electing two Class II directors, while two Class III directors will be elected at the 2007 annual meeting of stockholders and two Class I directors will be elected at the 2008 annual meeting of stockholders. Once elected, directors serve until their respective successors are duly elected and qualified.

      Management’s Class II nominees for election by the stockholders are John S. Patton and Steven T. Thornton. Both Dr. Patton and Mr. Thornton are current members of our Board of Directors and, if elected, they will serve as directors until our annual meeting of stockholders in 2009 and until their successors are elected and qualified. If either nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as we may designate.

      If a quorum is present and voting, the two nominees for Class II directors receiving the highest number of votes will be elected as the Class II directors. Abstentions and broker non-votes have no effect on the vote.

      The Board of Directors recommends a vote “FOR” each of the nominees named above.

      The following table sets forth, for our current directors, including the Class II nominees to be elected at this meeting, information with respect to their ages and background:

      The Board of Directors has determined that, other than Drs. Lim and Frost, each of the members of the Board of Directors is an independent director for purposes of the listing requirements of the American Stock Exchange.

Board Meetings and Committees

      The Board of Directors held eight meetings during the fiscal year ended December 31, 2005. The Board of Directors has an Audit Committee, a Compensation Committee and a Nominating and Governance Committee. During the last fiscal year, no director other than Steven T. Thornton attended fewer than 75% of the total number of meetings of the Board and all of the committees of the Board on which such director served during that period. Mr. Thornton joined the Board in June of 2005 and was unable to attend one Board meeting that was scheduled prior to his joining the Board as well as one special meeting of the Board.

      Audit Committee. The members of the Audit Committee are Kenneth J. Kelley (Chairman), Steven T. Thornton and Robert L. Engler. Each of the members of the Audit Committee satisfy the independence requirements established by the rules of the American Stock Exchange. Mr. Kelley is an audit committee financial expert, as defined in the rules of the Securities and Exchange Commission. The primary purpose of the Audit Committee is to oversee our accounting and financial reporting processes and the function of the Audit Committee includes retaining our independent auditors, reviewing their independence, reviewing and approving the planned scope of our annual audit, reviewing and approving any fee arrangements with our auditors, overseeing their audit work, reviewing and pre-approving any non-audit services that may be performed by them, reviewing the adequacy of accounting and financial controls, reviewing our critical accounting policies and reviewing and approving any related party transactions. The Audit Committee held six meetings during the fiscal year ended December 31, 2005.

      Compensation Committee. The members of the Compensation Committee are Steven T. Thornton (Chairman), Robert L. Engler, Kenneth J. Kelley and John S. Patton. Each of the members of the Compensation Committee satisfy the independence requirements established by the rules of the American Stock Exchange. The primary purpose of the Compensation Committee is to discharge the Board’s responsibilities relating to compensation and benefits of our executive officers. The Compensation Committee recommends the salary and bonus earned by the Chief Executive Officer, reviews and approves salary and bonus levels for other executive officers, approves stock option grants to executive officers and other employees and approves all employment and severance agreements. The Compensation Committee held six meetings during the fiscal year ended December 31, 2005.

      Nominating and Governance Committee. The members of the Nominating and Governance Committee are Robert L. Engler (Chairman), Kenneth J. Kelley and Steven T. Thornton. Each of the members of the Nominating and Governance Committee satisfy the independence requirements established by the rules of the American Stock Exchange. The primary responsibilities of the Nominating and Governance Committee are to (i) identify individuals qualified to become Board members; (ii) select, or recommend to the Board, director nominees for each election of directors; (iii) develop and recommend to the Board criteria for selecting qualified director candidates; (iv) consider committee member qualifications, appointment and removal; (v) recommend applicable corporate governance principles, codes of conduct and compliance mechanisms, and (vi) provide oversight in the evaluation of the Board and each committee. The Nominating and Governance Committee held six meetings during the fiscal year ended December 31, 2005.

      The Nominating and Governance Committee’s goal is to assemble a Board of Directors that brings a variety of perspectives and skills derived from high quality business and professional experience. There are no

stated minimum criteria for director nominees, but the Nominating and Governance Committee believes that at least one member of the Board meet the criteria for an “audit committee financial expert” as defined by SEC rules, and that a majority of the members of the Board meet the definition of “independent director” under the rules of the American Stock Exchange. The Nominating and Governance Committee also believes it appropriate for certain key members of management to participate as members of the Board.

      When considering whether to recommend any candidate for inclusion in the Board’s slate of recommended director nominees, including candidates recommended by our stockholders, the Nominating and Governance Committee will review the candidate’s integrity, business acumen, age, experience, commitment, diligence, conflicts of interest, existing time commitments and the ability to act in the interests of all stockholders. Once a potential qualified candidate is identified, one or more members of the Nominating and Governance Committee will interview that candidate. The committee may also ask the candidate to meet with non-committee members of the Board and/or members of management and, if the committee believes a candidate would be a valuable addition to the Board, it will recommend that candidate to the full Board.

      Pursuant to the terms of its charter, the Nominating and Governance Committee will consider qualified director candidates suggested by our stockholders. Stockholders may recommend individuals for the Nominating and Governance Committee to consider as potential director candidates by submitting the candidate’s name, contact information and biographical information in writing to the “Halozyme Nominating and Governance Committee” c/o Corporate Secretary, 11588 Sorrento Valley Road, Suite 17, San Diego, California 92121. The biographical information and background materials will be forwarded to the Nominating and Governance Committee for its review and consideration. The committee’s review of candidates identified by our stockholders is essentially identical to the review process for candidates identified by the committee. The Nominating and Governance Committee will review periodically whether a more formal policy regarding stockholder nominations should be adopted. In addition to the process discussed above regarding the consideration of the Nominating and Governance Committee of candidates suggested by our stockholders, our Bylaws contain provisions that address the process by which a stockholder may nominate an individual to stand for election to our Board at our annual meeting of stockholders.

Communications with Directors

      Any stockholder who desires to contact any members of our Board of Directors may do so by writing to: Board of Directors, c/o Corporate Secretary, 11588 Sorrento Valley Road, Suite 17, San Diego, California 92121. Communications received in writing are distributed to the Chairman of the Board or the other members of the Board as appropriate depending on the facts and circumstances outlined in the communication received. Alternatively, any stockholder who desires to contact an independent member of our Board of Directors directly, may contact the Chairman of our Board of Directors, Kenneth J. Kelley, electronically by sending an email to the following address: kkelley@halozyme.com.

Director Attendance at Annual Meetings

      Although we do not have a formal policy regarding attendance by members of the Board at our annual meeting of stockholders, we encourage directors to attend. Drs. Lim, Frost and Engler attended our annual meeting of stockholders in 2005. Mr. Thornton was not a member of the Board at the time of this meeting.

Committee Charters

      The Board has adopted a charter for each of the committees described above and links to these charters are available on our website, www.halozyme.com.

Code of Ethics

      The Board has adopted a Code of Conduct and Ethics that applies to all of our employees, officers and directors. A copy of our Code of Conduct and Ethics is currently available on our website, www.halozyme.com. Please note that the information on our website is not incorporated by reference in this Proxy Statement.

PROPOSAL NO. 2

APPROVAL OF AMENDMENTS TO THE AMENDED AND RESTATED ARTICLES OF INCORPORATION TO INCREASE THE AUTHORIZED NUMBER OF SHARES OF COMMON STOCK FROM 100,000,000 TO 150,000,000 AND TO ELIMINATE OUTDATED REFERENCES TO FORMER DIRECTORS

      The Board has adopted, subject to stockholder approval, amendments to our Amended and Restated Articles of Incorporation (the “Articles”) to increase our authorized number of shares of Common Stock from 100,000,000 to 150,000,000 and to remove outdated references to individuals that no longer serve on the Board.

Background of Proposal

      Under Nevada law, we may only issue shares of Common Stock to the extent such shares have been authorized for issuance under the Articles. The Articles currently authorize the issuance of up to 100,000,000 shares of Common Stock, each having a par value of one-tenth of one cent ($0.001). However, as of March 1, 2006, approximately 60.3 million shares of Common Stock were issued and outstanding and approximately 20.0 million unissued shares were reserved for issuance (i) under our equity compensation plans and (ii) upon exercise of outstanding warrants, leaving approximately 19.7 million shares of Common Stock unissued and unreserved. In order to ensure sufficient shares of Common Stock will be available for issuance by us, the Board of Directors has approved, subject to stockholder approval, amendments to our Articles to increase the number of shares of such Common Stock authorized for issuance from 100,000,000 to 150,000,000.

      The Articles also currently list the five members of the Board as of March 11, 2004 (the date that the Articles were filed). The composition and size of the Board has changed since that time and the Board has approved, subject to stockholder approval, amendments to our Articles that remove references to specific Board size as well as the names of particular individuals on the Board.

Purpose and Effect of the Amendments

      The principal purpose of the proposed amendment to the Articles is to authorize additional shares of Common Stock, which will be available in the event the Board determines that it is necessary or appropriate to permit future stock splits in the form of stock dividends, to raise additional capital through the sale of equity securities, to acquire another company or its assets, to establish strategic relationships with corporate partners, to provide equity incentives to employees and officers or for other corporate purposes. The availability of additional shares of Common Stock is particularly important in the event that the Board needs to undertake any of the foregoing actions on an expedited basis and thus to avoid the time and expense of seeking stockholder approval in connection with the contemplated issuance of Common Stock. If the amendments are approved by the stockholders, the Board does not intend to solicit further stockholder approval prior to the issuance of any additional shares of Common Stock, except as may be required by applicable law.

      The increase in authorized common stock will not have any immediate effect on the rights of existing stockholders. However, the Board will have the authority to issue authorized Common Stock without requiring future stockholder approval of such issuances, except as may be required by applicable law. To the extent that additional authorized shares are issued in the future, they may decrease the existing stockholders’ percentage equity ownership and, depending on the price at which they are issued, could be dilutive to the existing stockholders. The holders of Common Stock have no preemptive rights and the Board has no plans to grant such rights with respect to any such shares.

      The increase in the authorized number of shares of Common Stock and the subsequent issuance of such shares could have the effect of delaying or preventing a change in control of Halozyme without further action by the stockholders. Shares of authorized and unissued Common Stock could, within the limits imposed by applicable law, be issued in one or more transactions which would make a change in control of Halozyme

more difficult, and therefore less likely. Any such issuance of additional stock could have the effect of diluting the earnings per share and book value per share of outstanding shares of common stock and such additional shares could be used to dilute the stock ownership or voting rights of a person seeking to obtain control of Halozyme.

      The Board is not currently aware of any attempt to take over or acquire Halozyme. While it may be deemed to have potential anti-takeover effects, the proposed amendments to increase the authorized Common Stock are not prompted by any specific effort or takeover threat currently perceived by management.

      If this proposal is approved by the stockholders, the first paragraph of Article IV of the Articles will be amended to read in its entirety substantially as follows:

      In addition, the Articles currently list the five Board members that were sitting on March 11, 2004 (the date that the Articles were filed with the Nevada Secretary of State). Since that time the size and composition of the Board has changed as certain directors left the Board and others were added. If this proposal is approved by the stockholders, Article V of the Articles will be amended to read in its entirety substantially as follows:

      These proposed amendments to the Articles are set forth in Appendix A. The additional shares of Common Stock to be authorized pursuant to the proposed amendment will be of the same class of common stock as is currently authorized under the Articles. If approved, this proposal will become effective upon the filing of Amended and Restated Articles of Incorporation with the Secretary of State of the State of Nevada containing substantially these amendments, which Halozyme will do promptly after the annual meeting.

Required Vote and Board of Directors Recommendation

      Approval of this proposal requires the affirmative vote of the holders of a majority of the shares of our Common Stock outstanding on the Record Date. Abstentions and broker non-votes will be counted as present for purposes of determining if a quorum is present, but will have the same effect as a negative vote on the outcome of this proposal.

      The Board believes that the proposed amendments to the Articles are in the best interests of Halozyme and its stockholders for the reasons stated above. Therefore, the Board unanimously recommends a vote “FOR” amendments to our Amended and Restated Articles of Incorporation to increase the number of authorized shares of Common Stock from 100,000,000 to 150,000,000 and to eliminate references to former directors.

PROPOSAL NO. 3

APPROVAL OF THE HALOZYME THERAPEUTICS, INC.

2005 OUTSIDE DIRECTORS’ STOCK PLAN

      The Board of Directors adopted the Halozyme Therapeutics, Inc. 2005 Outside Director’s Stock Plan (the “Director Plan”), in June 2005.

      The Board believes that the Company must offer competitive compensation, including an equity incentive program, if it is to continue to successfully attract and retain the best possible directors. The Board expects that the Director Plan will be an important factor in attracting and retaining the high caliber directors essential

to our success, in motivating such directors to strive to increase the value of the Company for its stockholders and in aligning the interest of the directors and the stockholders.

Summary of the Director Plan

      The following is a summary of the material terms of the Director Plan. It is qualified in its entirety by the specific language of the Director Plan, which is available to any stockholder upon request.

      General. The Director Plan provides to members of the Board of Directors who are not employees of the Company or of any subsidiary or parent of the Company (“Outside Directors”) the (i) automatic grant of nonstatutory stock options, and (ii) automatic grant of restricted stock. The Director Plan is intended to qualify as a “formula plan” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934.

      Authorized Shares. A maximum of 500,000 of the authorized but unissued or reacquired shares of our Common Stock may be issued under the Director Plan. If any award expires, lapses or otherwise terminates for any reason without having been exercised or settled in full, or if shares subject to forfeiture or repurchase are forfeited or repurchased by the Company, any such shares that are reacquired or subject to such a terminated award will again become available for issuance under the Director Plan. If shares are surrendered in satisfaction of tax obligations, such shares shall not be deemed to be issued under the Director Plan. Upon any stock dividend, stock split, reverse stock split, recapitalization or similar change in our capital structure, appropriate adjustments will be made to the shares subject to the Director Plan, to the terms applicable to any automatic grant of awards described below, and to all outstanding awards.

      Administration. The Director Plan is intended to operate automatically without discretionary administration. To the extent administration is necessary, it will be performed by the Board or a committee of the Board. (For purposes of this discussion, the term “Board” refers to either the Board of Directors or such committee.) The Director Plan will be administered in a manner intended to permit awards to be exempt from Section 16(b) of the Securities Exchange Act of 1934 in accordance with Rule 16b-3 thereunder. The Board will approve forms of award agreements for use under the Director Plan, determine the terms and conditions of awards consistent with the requirements of the Director Plan, and construe and interpret the terms of the Director Plan and awards granted under it. However, the Board has no discretion to select the Outside Directors who are granted awards under the Director Plan.

      Eligibility. Only directors of the Company who are Outside Directors at the time of grant are eligible to participate in the Director Plan. Currently, four Outside Directors are eligible for the Director Plan.

      Automatic Grant of Stock Options. Stock options will be granted automatically under the Director Plan. Each person who first becomes an Outside Director on or after the Director Plan’s adoption in June 2005 shall be granted on the date he or she becomes an Outside Director an option (an “Initial Option”) for ten thousand (10,000) shares of Common Stock. In addition, following stockholder approval of the Director Plan each Outside Director who has served on the Board for at least six (6) full months prior to an annual meeting of the stockholders shall be granted an Option (“Annual Option”) to purchase ten thousand (10,000) shares immediately following such annual meeting.

      Terms and Conditions of Stock Options. Each Initial Option and Annual Option granted under the Director Plan will be evidenced by a written agreement specifying the number of shares subject to the option and the other terms and conditions of the option, consistent with the provisions of the Director Plan. The per-share exercise price for each Option will be equal to the fair market value of a share of our Common Stock on the date of grant. Generally, the fair market value of the Common Stock is the closing price per share on the date of grant as quoted by the national or regional securities exchange or market system on which the Common Stock is listed. The closing price of our Common Stock as reported on the American Stock Exchange on March 16, 2006 was $3.39 per share.

      The Director Plan provides that the option exercise price may be paid in cash, by check, by tender or attestation of previously owned shares, by assignment of the proceeds of a sale with respect to some or all of the shares acquired upon the exercise or by any other legal means approved by the Board.

      Subject to stockholder approval of the Director Plan, Initial Options will become vested and exercisable in full on the later of the date six (6) months from the grant date or the next annual meeting following the grant date. Annual Options will become vested and exercisable in full on the date immediately preceding the annual meeting following the grant date. Option vesting is subject to the Outside Director’s continuous service to the Company. Unless earlier terminated under the terms of the Director Plan or the option agreement, each option will remain exercisable for ten (10) years after the date of grant. An option may be transferred or assigned to the extent permitted by the Board and set forth in the option agreement.

      Automatic Grant of Restricted Stock. Awards of restricted stock will be granted automatically under the Director Plan. Initial Grants and Annual Grants of restricted stock covering fifteen thousand (15,000) shares each shall be granted on the same schedule and on the same basis as Initial Options and Annual Options.

      Terms and Conditions of Restricted Stock. Each award of restricted stock granted under the Director Plan will be evidenced by a written agreement specifying the number of shares subject to the award and the other terms and conditions of the award, consistent with the provisions of the Director Plan.

      Subject to stockholder approval of the Director Plan, Initial Grants of restricted stock vest in full on the first day the holder may trade Company Stock in compliance with the insider trading policy of the Company following the later of (a) the six month anniversary of the grant date, or (b) the first annual meeting of stockholders following the grant date. Annual Grants of restricted stock vest in full on the first day the holder may trade Company stock in compliance with the Company’s insider trading policy following the date immediately preceding the first annual meeting of stockholders following the grant date.

      Change in Control. If a change in control (as defined in the Director Plan) occurs, all stock options and restricted stock shall be 100% vested prior to the effective date of any change in control. As a result of such a change in control, the surviving, continuing, successor or purchasing corporation or parent corporation thereof may either assume all outstanding awards or substitute new awards having an equivalent value.

      Termination or Amendment. The Director Plan has a term of 10 years. The Director Plan shall continue in effect until the end of the term or until the earlier of its termination by the Board or the date on which all of the shares of Common Stock available for issuance under the Director Plan have been issued and all restrictions on such shares under the terms of the Director Plan have lapsed. The Board may terminate or amend the Director Plan at any time, provided that no amendment may be made without stockholder approval if the Board deems such approval necessary for compliance with any applicable tax or securities law or other regulatory requirements, including the requirements of any stock exchange or market system on which the Common Stock of the Company is then listed. No termination or amendment may affect any outstanding award unless expressly provided by the Board, and, in any event, may not adversely affect an outstanding award without the consent of the Outside Director unless necessary to comply with any applicable law, regulation or rule.

Summary of U.S. Federal Income Tax Consequences

      The following summary is intended only as a general guide to the U.S. federal income tax consequences of participation in the Director Plan and does not attempt to describe all possible federal or other tax consequences of such participation or tax consequences based on particular circumstances.

      Nonstatutory Stock Options. All stock options shall be nonstatutory stock options having no special tax status. An Outside Director generally recognizes no taxable income upon receipt of such an option. Upon exercising a nonstatutory stock option, the Outside Director normally recognizes ordinary income equal to the difference between the exercise price paid and the fair market value of the shares on the date when the option is exercised or such later date as the shares become vested and free of any restrictions on transfer (the later of such dates being referred to as the “determination date”). Upon the sale of stock acquired by the exercise of a nonstatutory stock option, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the determination date, will be taxed as capital gain or loss. The Company generally should be entitled to a tax deduction equal to the amount of ordinary income recognized by the Outside

Director as a result of the exercise of a nonstatutory stock option, except to the extent such deduction is limited by applicable provisions of the Internal Revenue Code.

      Restricted Stock. Acquisitions of restricted stock receive tax treatment that is similar to that of exercises of nonstatutory stock options. An Outside Director acquiring restricted stock normally recognizes ordinary income equal to the difference between the amount, if any, the Outside Director paid for the restricted stock and the fair market value of the shares on the determination date. The Outside Director may elect, pursuant to Section 83(b) of the Internal Revenue Code, to treat the acquisition date as the determination date by filing an election with the Internal Revenue Service. Upon the sale of restricted stock, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the determination date, will be taxed as capital gain or loss. The Company generally should be entitled to a tax deduction equal to the amount of ordinary income recognized by the Outside Director as a result of the acquisition of restricted stock, except to the extent such deduction is limited by applicable provisions of the Internal Revenue Code.

New Plan Benefits

      Only Outside Directors are eligible to participate in the Director Plan.                      shares of our Common Stock underlying the automatic grants of stock options and                      shares of restricted stock will be received under the Director Plan during the 2006 fiscal year by the Outside Directors, assuming no new Outside Directors not currently anticipated join the Board.

Vote Required and Board of Directors Recommendation

      Approval of this proposal would require the affirmative vote of a majority of the votes cast affirmatively or negatively on the proposal at the annual meeting of stockholders, as well as the presence of a quorum representing a majority of all outstanding shares of common stock of the Company, either in person or by proxy. Abstentions and broker non-votes would be counted for purposes of determining the presence of a quorum but otherwise would not have any effect on the outcome of the proposal.

      The Board believes that the adoption of the Director Stock Plan is in the best interests of Halozyme and its stockholders for the reasons stated above. Therefore, the Board unanimously recommends a vote “FOR” approval of the 2005 Stock Plan.

PROPOSAL NO. 4

APPROVAL OF THE HALOZYME THERAPEUTICS, INC.

2006 STOCK PLAN

      In March 2006, the Board of Directors adopted, subject to stockholder approval, the Company’s 2006 Stock Plan (the “2006 Plan”). The 2006 Plan has a share reserve of 2,000,000 shares. As of March 31, 2006,                      shares were subject to options under the Company’s existing stock option plans and                      shares remained eligible for grant under those plans.

      The Company believes that appropriate equity incentives are critical to attracting and retaining the best employees in its industry. The approval of this proposal will enable the Company to continue to provide such incentives.

      The Board has full discretion to determine the number of awards to be granted to participants under the 2006 Plan, subject to an annual limitation on the total number of awards that may be granted to any employee. Prior to the Annual Meeting, the Company will not grant any awards under the 2006 Plan.

Summary of the 2006 Plan

      The following is a summary of the material terms of the 2006 Plan. It is qualified in its entirety by the specific language of the 2006 Plan, a copy of which is available to any stockholder upon request.

      General. The 2006 Plan provides for the grant of incentive and nonstatutory stock options as well as stock appreciation rights, restricted stock, restricted stock units, performance units and shares and other stock-based awards. Incentive stock options granted under the 2006 Plan are intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). Nonstatutory stock options granted under the 2006 Plan are not intended to qualify as incentive stock options under the Code.

      Purpose. The purpose of the 2006 Plan is to advance the interests of the Company and its stockholders by providing an incentive to attract and retain persons eligible to receive options under the 2006 Plan and by motivating such persons to contribute to the growth and profitability of the Company.

      Administration. The 2006 Plan is administered by the Board of Directors and its designees. The Board has the power to construe and interpret the 2006 Plan and, subject to the provisions of the 2006 Plan, to determine the persons to whom and the dates on which awards will be granted, the number of shares to be subject to each award, the time or times during the term of each award within which all or a portion of such award may be exercised, the exercise price, the type of consideration to be paid upon exercise of an award, and other terms of the award. The Board of Directors is authorized to delegate administration of the 2006 Plan to a committee of outside directors. The Board has delegated administration of the 2006 Plan to the Compensation Committee of the Board. As used herein with respect to the 2006 Plan, the “Board” refers to the Compensation Committee, as well as to the Board of Directors itself.

      Stock Subject to the 2006 Plan. The share reserve under the 2006 Plan will be equal to 2,000,000 shares. If awards granted under the 2006 Plan expire, are cancelled or otherwise terminate without being exercised, the shares of Common Stock subject to such expired, cancelled or terminated awards will then be available for grant under the 2006 Plan. In addition, to the extent (a) shares are surrendered in exercise of awards or payment of tax, or (b) awards are settled in cash, such shares will not be deemed to be issued under the Plan.

      In general, no more than                      shares may be issued under the Plan pursuant to restricted stock awards, restricted stock unit awards and performance awards. Except for                      shares, such awards may generally not vest more rapidly than over three years or pursuant to a one year performance period.

      Eligibility. Awards other than incentive stock options generally may be granted only to employees, directors and consultants of the Company, or certain related entities or designated affiliates. An incentive stock option can only be granted to a person who, on the effective date of grant, is an employee of the Company, a parent corporation or a subsidiary corporation. As of March 31, 2006, approximately 34 persons would have been eligible to receive grants under the 2006 Plan.

      No incentive stock options may be granted under the 2006 Plan to any person who, at the time of the grant, owns (or is deemed to own) stock possessing more than 10% of the total combined voting power of the Company, or any of its parent or subsidiary corporations, unless the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant, and the term of the option does not exceed 5 years from the date of grant. The aggregate fair market value, determined at the time of grant, of the shares of Common Stock with respect to which incentive stock options granted under the 2006 Plan are exercisable for the first time by an optionee during any calendar year (under all such plans of the Company and its parent and subsidiary corporations) may not exceed $100,000. In order to permit awards to qualify as “performance based compensation” under Code Section 162(m) no employee may be granted awards under the 2006 Plan in excess of the following in each fiscal year of the Company:

Options and Stock Appreciation Rights

      The following is a description of the general terms of options and stock appreciation rights under the 2006 Plan. Individual grants may have terms that differ from those described below.

      Exercise Price; Payment. The exercise price of incentive stock options under the 2001 Option Plan may not be less than the fair market value of the Common Stock subject to the option on the date of the option grant, and in some cases (see “Eligibility” above), may not be less than 110% of such fair market value. The exercise price of nonstatutory stock options and stock appreciation rights may not be less than the fair market value of the stock subject to the award on the date of the option grant. On March 16, 2006, the closing price of the Company’s Common Stock as reported on the American Stock Exchange was $3.39 per share. The exercise price of options granted under the 2006 Plan must be paid: (i) in cash, by check or cash equivalent, (ii) by tender to the Company, or attestation to the ownership of shares of Common Stock of the Company owned by the optionee having a fair market value not less than the exercise price, (iii) for optionees who are employees, in the Company’s sole and absolute discretion, by delivery of a promissory note, (iv) in any other form of legal consideration acceptable to the Board, or (v) any combination of the above.

      No Repricing. The 2006 Plan does not permit the Company to lower the exercise price of options or stock appreciation rights or to exchange options or stock appreciation rights for awards with a lower exercise price without further stockholder approval.

      Exercise. Options and stock appreciation rights granted under the 2006 Plan may become exercisable (“vest”) in cumulative increments as determined by the Board provided that the holder’s employment by, or service as a director or consultant to the Company or certain related entities or designated affiliates (“service”) continues from the date of grant until the applicable vesting date. Shares covered by awards granted under the 2006 Plan may be subject to different vesting terms. The Board has the power to accelerate the time during which an award may be exercised.

      Term. The maximum term of options and stock appreciation rights under the 2006 Plan is ten years, except that in certain cases (see “Eligibility” above) the maximum term is five years. The 2006 Plan provides for earlier termination of an award due to the holder’s cessation of service.

      Restrictions on Transfer. Incentive stock options granted under the 2006 Plan may not be transferred except by will or by the laws of descent and distribution, and may be exercised during the lifetime of the person to whom the option is granted only by such person. A nonstatutory stock option or stock appreciation right is not transferable in any manner other than (i) by will or by the laws of descent and distribution, (ii) by written designation of a beneficiary taking effect upon the death of the optionee, (iii) by delivering written notice to the Company that the optionee will be gifting to certain family members or other specific entities controlled by or for the benefit of such family members, and such other transferees as the Board may approve.

Restricted Stock Units

      The Board may grant restricted stock units under the 2006 Plan that represent a right to receive shares of our common stock at a future date determined in accordance with the participant’s award agreement. No monetary payment is required for receipt of restricted stock units or the shares issued in settlement of the award, the consideration for which is furnished in the form of the participant’s services to the company. The Board may grant restricted stock unit awards subject to the attainment of one or more performance goals similar to those described below in connection with performance awards, or may make the awards subject to vesting conditions similar to those applicable to restricted stock awards. Unless otherwise provided by the Board, a participant will forfeit any restricted stock units which have not vested prior to the participant’s termination of service. Participants have no voting rights or rights to receive cash dividends with respect to restricted stock unit awards until shares of common stock are issued in settlement of such awards. However, the Board may grant restricted stock units that entitle their holders to receive dividend equivalents, which are rights to receive additional restricted stock units for a number of shares whose value is equal to any cash dividends we pay.

Restricted Stock Awards

      The Board may grant restricted stock awards under the 2006 Plan either in the form of a restricted stock purchase right, giving a participant an immediate right to purchase common stock, or in the form of a restricted stock bonus, for which the participant furnishes consideration in the form of services to the company. The Board determines the purchase price payable under restricted stock purchase awards, which may be less than the then current fair market value of our common stock. Restricted stock awards may be subject to vesting conditions based on such service or performance criteria as the Board specifies, including the attainment of one or more performance goals similar to those described below in connection with performance awards. Shares acquired pursuant to a restricted stock award may not be transferred by the participant until vested. Unless otherwise provided by the Board, a participant will forfeit any shares of restricted stock as to which the restrictions have not lapsed prior to the participant’s termination of service. Participants holding restricted stock will generally have the right to vote the shares and to receive any dividends paid, except that dividends or other distributions paid in shares will be subject to the same restrictions as the original award.

Performance Awards

      The Board may grant performance awards subject to such conditions and the attainment of such performance goals over such periods as the determines in writing and sets forth in a written agreement between the company and the participant. To the extent compliance with Section 162(m) of the Code is desired, a committee comprised solely of “outside directors” under Section 162(m) shall act with respect to performance awards, and “Board” as used in this section shall mean this committee. These awards may be designated as performance shares or performance units. Performance shares and performance units are unfunded bookkeeping entries generally having initial values, respectively, equal to the fair market value determined on the grant date of a share of common stock and a value set by the Board. Performance awards will specify a predetermined amount of performance shares or performance units that may be earned by the participant to the extent that one or more predetermined performance goals are attained within a predetermined performance period. To the extent earned, performance awards may be settled in cash, shares of common stock (including shares of restricted stock) or any combination thereof.

      Prior to the beginning of the applicable performance period or such later date as permitted under Section 162(m) of the Code, the Board will establish one or more performance goals applicable to the award. Performance goals will be based on the attainment of specified target levels with respect to one or more measures of business or financial performance of the company and each subsidiary corporation consolidated with the company for financial reporting purposes, or such division or business unit of the company as may be selected by the Board. The Board, in its discretion, may base performance goals on one or more of the following such measures: sales revenue, gross margin, operating margin, operating income, pre-tax profit, earnings before stock-based compensation expense, interest, taxes, depreciation and amortization, net income, expenses, the market price of our common stock, earnings per share, return on stockholder equity, return on capital, return on net assets, economic value added, market share, customer service, customer satisfaction, safety, total stockholder return, free cash flow, net operating income, operating cash flow, return on investment, employee satisfaction, employee retention, balance of cash, cash equivalents and marketable securities, product development, research and development expenses, completion of an identified special project, completion of a joint venture or other corporate transaction, or other measures as determined by the Board. The target levels with respect to these performance measures may be expressed on an absolute basis or relative to a standard specified by the Board. The degree of attainment of performance measures will be calculated in accordance with generally accepted accounting principles, but prior to the accrual or payment of any performance award for the same performance period, and, according to criteria established by the Board, excluding the effect (whether positive or negative) of changes in accounting standards or any extraordinary, unusual or nonrecurring item occurring after the establishment of the performance goals applicable to a performance award.

      Following completion of the applicable performance period, the Board will certify in writing the extent to which the applicable performance goals have been attained and the resulting value to be paid to the participant. The Board retains the discretion to eliminate or reduce, but not increase, the amount that would

otherwise be payable on the basis of the performance goals attained to a participant who is a “covered employee” within the meaning of Section 162(m) of the Code. However, no such reduction may increase the amount paid to any other participant. The Board may make positive or negative adjustments to performance award payments to participants other than covered employees to reflect the participant’s individual job performance or other factors determined by the Board. In its discretion, the Board may provide for the payment to a participant awarded performance shares of dividend equivalents with respect to cash dividends paid on the company’s common stock. The Board may provide for performance award payments in lump sums or installments. If any payment is to be made on a deferred basis, the Board may provide for the payment of dividend equivalents or interest during the deferral period.

      Unless otherwise provided by the Board, if a participant’s service terminates due to the participant’s death or disability prior to completion of the applicable performance period, the final award value will be determined at the end of the performance period on the basis of the performance goals attained during the entire performance period but will be prorated for the number of months of the participant’s service during the performance period. If a participant’s service terminates prior to completion of the applicable performance period for any other reason, the 2006 Plan provides that, unless otherwise determined by the Board, the performance award will be forfeited. No performance award may be sold or transferred other than by will or the laws of descent and distribution prior to the end of the applicable performance period.

Deferred Compensation Awards

      The 2006 Plan authorizes the Board to establish a deferred compensation award program. If and when implemented, participants designated by the Board who are officers, directors or members of a select group of highly compensated employees may elect to receive, in lieu of compensation otherwise payable in cash or in lieu of cash or shares of common stock issuable upon the exercise or settlement of stock options, stock appreciation rights or performance share or performance unit awards, an award of deferred stock units. Each such stock unit represents a right to receive one share of our common stock at a future date determined in accordance with the participant’s award agreement. Deferred stock units are fully vested upon grant and will be settled by distribution to the participant of a number of whole shares of common stock equal to the number of stock units subject to the award as soon as practicable following the earlier of the date on which the participant’s service terminates or a settlement date elected by the participant at the time of his or her election to receive the deferred stock unit award. Participants are not required to pay any additional consideration in connection with the settlement of deferred stock units. A holder of deferred stock units has no voting rights or other rights as a stockholder until shares of common stock are issued to the participant in settlement of the stock units. However, participants holding deferred stock units will be entitled to receive dividend equivalents with respect to any payment of cash dividends on an equivalent number of shares of common stock. Such dividend equivalents will be credited in the form of additional whole and fractional stock units determined in accordance with a method specified by the Board in the participant’s award agreement. Prior to settlement, deferred stock units may not be assigned or transferred other than by will or the laws of descent and distribution.

Other Stock-Based Awards

      The Plan permits the Board to grant other awards based on the Company’s stock or on dividends on the Company’s stock.

Effect of Certain Corporate Events

      In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification or similar change in the capital structure of the Company, appropriate adjustments will be made in the number and class of shares subject to the 2006 Plan and to any outstanding awards, in the aggregate and Section 162(m) per employee grant limits (see “Federal Income Tax Information — Potential Limitation on Company Deductions,” below), and in the exercise price per share of any outstanding awards. Any fractional share resulting from an adjustment will be rounded down to the nearest whole number, and at

no time will the exercise price of any option or stock appreciation right be decreased to an amount less than par value of the stock subject to the award.

      If a change in control occurs, the surviving, continuing, successor or purchasing corporation or parent corporation thereof may either assume the Company’s rights and obligations under the outstanding awards or substitute substantially equivalent awards for such corporation’s stock. Awards that are not assumed, replaced or exercised prior to the change in control will terminate. The Board may grant awards that will accelerate in connection with a change in control. The acceleration of an award in the event of an acquisition or similar corporate event may be viewed as an anti-takeover provision, which may have the effect of discouraging a proposal to acquire or otherwise obtain control of the Company.

Duration, Amendment and Termination

      The Board may amend or terminate the 2006 Plan at any time. If not earlier terminated, the 2006 Plan will expire on the tenth anniversary of stockholder approval.

      The Board may also amend the 2006 Plan at any time or from time to time. However, no amendment authorized by the Board will be effective unless approved by the stockholders of the Company if the amendment would: (i) increase the number of shares reserved for options under the 2006 Plan; (ii) change the class of persons eligible to receive incentive stock options; or (iii) modify the 2006 Plan in any other way if such modification requires stockholder approval under applicable law, regulation or rule.

Specific Grants

      Awards under the 2006 Plan are discretionary. Accordingly, it is not possible to determine the number of awards that may be granted under the 2006 Plan to specific individuals.

Federal Income Tax Information

      Incentive Stock Options. An optionee recognizes no taxable income for regular income tax purposes as the result of the grant or exercise of an incentive stock option. Optionees who do not dispose of their shares for two years following the date the incentive stock option was granted or within one year following the exercise of the option will normally recognize a long-term capital gain or loss equal to the difference, if any, between the sale price and the purchase price of the shares. If an optionee satisfies both such holding periods upon a sale of the shares, the Company will not be entitled to any deduction for federal income tax purposes. If an optionee disposes of shares either within two years after the date of grant or within one year from the date of exercise (referred to as a “disqualifying disposition”), the difference between the fair market value of the shares on the exercise date and the option exercise price (not to exceed the gain realized on the sale if the disposition is a transaction with respect to which a loss, if sustained, would be recognized) will be taxed as ordinary income at the time of disposition. Any gain in excess of that amount will be a capital gain. If a loss is recognized, there will be no ordinary income, and such loss will be a capital loss. A capital gain or loss will be long-term if the optionee’s holding period is more than 12 months. Any ordinary income recognized by the optionee upon the disqualifying disposition of the shares generally should be deductible by the Company for federal income tax purposes, except to the extent such deduction is limited by applicable provisions of the Code or the regulations thereunder. The difference between the option exercise price and the fair market value of the shares on the exercise date of an incentive stock option is an adjustment in computing the optionee’s alternative minimum taxable income and may be subject to an alternative minimum tax which is paid if such tax exceeds the regular tax for the year. Special rules may apply with respect to certain subsequent sales of the shares in a disqualifying disposition, certain basis adjustments for purposes of computing the alternative minimum taxable income on a subsequent sale of the shares and certain tax credits which may arise with respect to optionees subject to the alternative minimum tax.

      Nonstatutory Stock Options and Stock Appreciation Rights. Nonstatutory stock options and stock appreciation rights have no special tax status. A holder of these awards generally does not recognize taxable income as the result of the grant of such award. Upon exercise of a nonstatutory stock option or stock appreciation right, the holder normally recognizes ordinary income in an amount equal to the difference

between the exercise price and the fair market value of the shares on the exercise date. If the holder is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of stock acquired by the exercise of a nonstatutory stock option or stock appreciation right, any gain or loss, based on the difference between the sale price and the fair market value on the exercise date, will be taxed as capital gain or loss. A capital gain or loss will be long-term if the holding period of the shares is more than 12 months. The Company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the optionee as a result of the exercise of a nonstatutory stock option or stock appreciation right, except to the extent such deduction is limited by applicable provisions of the Code or the regulations thereunder. No tax deduction is available to the Company with respect to the grant of a nonstatutory stock option or stock appreciation right or the sale of the stock acquired pursuant to such grant.

      Restricted Stock. A participant acquiring restricted stock generally will recognize ordinary income equal to the fair market value of the shares on the “determination date.” The “determination date” is the date on which the participant acquires the shares unless the shares are subject to a substantial risk of forfeiture and are not transferable, in which case the determination date is the earlier of (i) the date on which the shares become transferable or (ii) the date on which the shares are no longer subject to a substantial risk of forfeiture. If the determination date is after the date on which the participant acquires the shares, the participant may elect, pursuant to Section 83(b) of the Code, to have the date of acquisition be the determination date by filing an election with the Internal Revenue Service no later than 30 days after the date on which the shares are acquired. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of shares acquired pursuant to a restricted stock award, any gain or loss, based on the difference between the sale price and the fair market value on the determination date, will be taxed as capital gain or loss. We generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant on the determination date, except to the extent such deduction is limited by applicable provisions of the Code.

      Performance and Restricted Stock Unit Awards. A participant generally will recognize no income upon the receipt of a performance share, performance unit or restricted stock unit award. Upon the settlement of such awards, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and the fair market value of any substantially vested shares received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. If the participant receives shares of restricted stock, the participant generally will be taxed in the same manner as described above (see discussion under “Restricted Stock”). Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value on the “determination date” (as defined above under “Restricted Stock”), will be taxed as capital gain or loss. The company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant on the determination date, except to the extent such deduction is limited by applicable provisions of the Code.

      Deferred Compensation Awards. A participant generally will recognize no income upon the receipt of deferred compensation awards. Upon the settlement of the awards, the participant normally will recognize ordinary income in the year of settlement in an amount equal to the fair market value of the shares received. Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the date they are transferred to the participant, will be taxed as capital gain or loss. The Company generally should be entitled to a deduction equal to the amount of ordinary income recognized by the participant, except to the extent such deduction is limited by applicable provisions of the Internal Revenue Code.

      Potential Limitation on Company Deductions. Code Section 162(m) denies a deduction to the Company for compensation paid to certain employees in a taxable year to the extent that compensation exceeds $1 million for a covered employee. It is possible that compensation attributable to stock options, when combined with all other types of compensation received by a covered employee from the Company, may cause this limitation to be exceeded in any particular year. Certain kinds of compensation, including qualified “performance-based compensation,” are disregarded for purposes of the deduction limitation. In accordance with applicable regulations issued under Section 162(m), compensation attributable to stock options and stock appreciation rights will qualify as performance-based compensation, provided that: (i) the option plan

contains a per-employee limitation on the number of shares for which options or stock appreciation rights may be granted during a specified period, (ii) the per-employee limitation is approved by the stockholders, (iii) the option is granted by a Compensation Committee comprised solely of “outside directors” (as defined in Section 162(m)) and (iv) the exercise price of the option or right is no less than the fair market value of the stock on the date of grant.

      For the aforementioned reasons, the 2006 Plan provides for an annual per employee limitation as required under Section 162(m) and the Company’s Compensation Committee is comprised solely of outside directors. Accordingly, options or stock appreciation rights granted by the Compensation Committee qualify as performance-based compensation, and the other awards subject to performance goals may qualify.

      Other Tax Consequences. The foregoing discussion is intended to be a general summary only of the federal income tax aspects of awards granted under the 2006 Plan; tax consequences may vary depending on the particular circumstances at hand. In addition, administrative and judicial interpretations of the application of the federal income tax laws are subject to change. Furthermore, no information is given with respect to state or local taxes that may be applicable. Participants in the 2006 Plan who are residents of or are employed in a country other than the United States may be subject to taxation in accordance with the tax laws of that particular country in addition to or in lieu of United States federal income taxes.

Vote Required and Board of Directors Recommendation

      Approval of this proposal would require the affirmative vote of a majority of the votes cast affirmatively or negatively on the proposal at the annual meeting of stockholders, as well as the presence of a quorum representing a majority of all outstanding shares of common stock of the Company, either in person or by proxy. Abstentions and broker non-votes would be counted for purposes of determining the presence of a quorum but otherwise would not have any effect on the outcome of the proposal.

      The Board believes that the adoption of the 2006 Stock Plan is in the best interests of Halozyme and its stockholders for the reasons stated above. Therefore, the Board unanimously recommends a vote “FOR” approval of the 2006 Stock Plan.

STOCK OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      The following table sets forth, as of March 1, 2006, certain information with respect to the beneficial ownership of our Common Stock by (i) each stockholder known by Halozyme to be the beneficial owner of more than 5% of our Common Stock, (ii) each director and director-nominee of Halozyme, (iii) each executive officer named in the Summary Compensation Table below, and (iv) all directors and executive officers of Halozyme as a group:

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      We have entered into indemnification agreements with each of our executive officers and directors containing provisions that may require us, among other things, to indemnify those officers and directors against liabilities that may arise by reasons of their status or service as officers or directors. The agreements also provide for Halozyme to advance to the officers and directors expenses that they expect to incur as a result of any proceeding against them as to which they could be indemnified. We also intend to execute such agreements with our future directors and executive officers.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers and directors and persons who beneficially own more than 10% of our Common Stock to file initial reports of beneficial ownership and reports of changes in beneficial ownership with the SEC. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms filed by such person.

      Based solely on our review of such forms furnished to us and written representations from certain reporting persons, we believe that all filing requirements applicable to our executive officers, directors and greater-than-10% stockholders were met.

APPOINTMENT OF INDEPENDENT AUDITORS

      The Audit Committee of the Board of Directors of Halozyme has not yet selected an independent auditor to audit the consolidated financial statements of Halozyme for the fiscal year ending December 31, 2006, as it is still reviewing various independent auditor candidates. Cacciamatta Accountancy Corporation has acted in such capacity since its appointment in fiscal year 2003. A representative of Cacciamatta Accountancy Corporation is expected to be present at the annual meeting and to make a statement. A representative of Cacciamatta Accountancy Corporation is also expected to be available to respond to appropriate questions.

      The following table sets forth the aggregate fees billed to Halozyme for the fiscal years ended December 31, 2005, and December 31, 2004, by Cacciamatta Accountancy Corporation:

      The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by our independent auditors. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services. The independent auditor and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditor in accordance with this pre-approval. The chair of the Audit Committee is also authorized, pursuant to delegated authority, to pre-approve additional services of up to $25,000 per engagement on a case-by-case basis, and such approvals are communicated to the full Audit Committee at its next meeting.

REPORT OF THE AUDIT COMMITTEE

      The Audit Committee oversees Halozyme’s financial reporting process on behalf of the Board of Directors. The Audit Committee consists of three directors each of whom, in the judgment of the Board, is an “independent director” as defined in the listing standards for The American Stock Exchange. The Audit Committee acts pursuant to a written charter that has been adopted by the Board of Directors.

      Management has the primary responsibility for the financial statements and the reporting process, including internal control systems. Our independent auditor, Cacciamatta Accountancy Corporation, is responsible for expressing an opinion as to the conformity of our audited financial statements with generally accepted accounting principles. The Audit Committee has reviewed and discussed the consolidated financial statements with management and Cacciamatta Accountancy Corporation.

      The Committee has also discussed and reviewed with the auditors all matters required to be disclosed in Statement on Auditing Standards No. 61 (Communication with Audit Committees). The Committee has met with Cacciamatta Accountancy Corporation, with and without management present, to discuss the overall scope of the Cacciamatta Accountancy Corporation audit, the results of its examinations, its evaluations of Halozyme’s internal controls and the overall quality of its financial reporting.

      The Audit Committee has received from the auditors a formal written statement describing all relationships between the auditors and Halozyme that might bear on the auditors’ independence consistent with Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), discussed with the auditors any relationships that may impact their objectivity and independence, and satisfied itself as to the auditors’ independence.

      Based on the review and discussions referred to above, the committee recommended to the Board of Directors that Halozyme’s audited financial statements be included in Halozyme’s Annual Report on Form 10-KSB for the fiscal year ended December 31, 2005.

STOCKHOLDER PROPOSALS TO BE PRESENTED AT NEXT ANNUAL MEETING

      Stockholder proposals may be included in our proxy materials for an annual meeting so long as they are provided to us on a timely basis and satisfy the other conditions set forth in applicable SEC rules. For a stockholder proposal to be included in our proxy materials for the 2007 annual meeting, the proposal must be received at our principal executive offices, addressed to the Secretary, not later than November      , 2006. Stockholder business that is not intended for inclusion in our proxy materials may be brought before the annual meeting so long as we receive notice of the proposal as specified by our Bylaws, addressed to the Secretary at our principal executive offices, not later than November      , 2006.

TRANSACTION OF OTHER BUSINESS

      At the date of this Proxy Statement, the Board of Directors knows of no other business that will be conducted at the 2006 annual meeting other than as described in this Proxy Statement. If any other matter or matters are properly brought before the meeting, or any adjournment or postponement of the meeting, it is the intention of the persons named in the accompanying form of proxy to vote the proxy on such matters in accordance with their best judgment.

If an outstanding Award for any reason expires or is terminated or canceled without having been exercised or settled in full, or if shares of Stock acquired pursuant to an Award subject to

forfeiture are forfeited, the shares of Stock allocable to the unexercised portion of such Award or such forfeiture shall again be available for issuance under the Plan.

For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” Any fractional share resulting from an adjustment pursuant to this Section 4.2 shall be rounded down to the nearest whole number, and in no event may the exercise or purchase price under any Award be decreased to an amount less than the par value, if any, of the stock subject to such Award.

The Board shall have the authority from time to time to vary the terms of any standard form of Award Agreement either in connection with the grant or amendment of an individual Award or in connection with the authorization of a new standard form or forms; provided, however, that the terms and conditions of any such new, revised or amended standard form or forms of Award Agreement are not inconsistent with the terms of the Plan.

      9.1     Effect of Change in Control on Options.

      9.2     Effect of Change in Control on Restricted Stock Awards. The Board may, in its discretion, provide in any Award Agreement evidencing a Restricted Stock Award that, in the event of a Change in Control, the lapsing of any Vesting Conditions applicable to the shares subject to the Restricted Stock Award held by a Participant whose Service has not terminated prior to such date shall be accelerated effective immediately prior to the consummation of the Change in Control to such extent as specified in such Award Agreement. Any acceleration of the lapsing of any Vesting Conditions that was permissible solely by reason of this Section 9.2 and the provisions of such Award Agreement shall be conditioned upon the consummation of the Change in Control.

      The grant of Awards and the issuance of shares of Stock pursuant to any Award shall be subject to compliance with all applicable requirements of federal, state and foreign law with respect to such securities and the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, no Award may be exercised or shares issued pursuant to an Award unless (i) a registration statement under the Securities Act shall at the time of such exercise or issuance be in effect with respect to the shares issuable pursuant to the Award or (ii) in the opinion of legal counsel to the Company, the shares issuable pursuant to the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to issuance of any Stock, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

      11.1     Tax Withholding in General. The Company shall have the right to deduct from any and all payments made under the Plan, or to require the Participant, through payroll withholding, cash payment or otherwise, including by means of a Cashless Exercise of an Option, to make adequate provision for, the federal, state, local and foreign taxes, if any, required by law to be withheld by the Participating Company Group with respect to an Award or the shares acquired pursuant thereto. The Company shall have no obligation to deliver shares of Stock, to release shares of Stock from an escrow established pursuant to an Award Agreement, or to make any payment in cash under the Plan until the Participating Company Group’s tax withholding obligations have been satisfied by the Participant.

      11.2     Withholding in Shares. The Company shall have the right, but not the obligation, to deduct from the shares of Stock issuable to a Participant upon the exercise or settlement of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair Market Value, as determined by the Company, equal to all or any part of the tax withholding obligations of the Participating Company Group. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall not exceed the amount determined by the applicable minimum statutory withholding rates.

12.     Termination or Amendment of Plan.

      The Board may amend, suspend or terminate the Plan at any time. However, without the approval of the Company’s stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.2) and (b) no other amendment of the Plan that would require approval of the Company’s stockholders under any applicable law, regulation or rule. No amendment, suspension or termination of the Plan shall affect any then outstanding Award unless expressly provided by the Board. In any event, no amendment, suspension or termination of the Plan may adversely affect any then outstanding Award without the consent of the Participant unless necessary to comply with any applicable law, regulation or rule.

13.     Miscellaneous Provisions.

      13.1     Repurchase Rights. Shares issued under the Plan may be subject to one or more repurchase options, or other conditions and restrictions as determined by the Board in its discretion at the time the Award is granted. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such transfer restrictions.

      13.2     Provision of Information. Each Participant shall be given access to information concerning the Company equivalent to that information generally made available to the Company’s common stockholders.

      13.3     Rights as Outside Director. No person, even though eligible pursuant to Section 5, shall have a right to be selected as a Participant, or, having been so selected, to be selected again as a Participant. Nothing in the Plan or any Award granted under the Plan shall confer on any Participant a right to remain an Outside Director, or interfere with or limit in any way any right of a Participating Company to terminate the Participant’s Service at any time.

      13.4     Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise or settlement of any Award.

      13.5     Beneficiary Designation. Subject to local laws and procedures, each Participant may file with the Company a written designation of a beneficiary who is to receive any benefit under the Plan to which the Participant is entitled in the event of such Participant’s death before he or she receives any or all of such benefit. Each designation will revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. If a married Participant designates a beneficiary other than the Participant’s spouse, the effectiveness of such designation may be subject to the consent of the Participant’s spouse. If a Participant dies without an effective designation of a beneficiary who is living at the time of the Participant’s death, the Company will pay any remaining unpaid benefits to the Participant’s legal representative.

      13.6     Rights as a Stockholder. A Participant shall have no rights as a stockholder with respect to any shares covered by an Award until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such shares are issued, except as provided in Section 4.2 or another provision of the Plan.

Halozyme Therapeutics, Inc.

2006 Stock Plan

1.     Establishment, Purpose and Term of Plan.

      1.1     Establishment. The Halozyme Therapeutics, Inc. 2006 Stock Plan (the “Plan”) is hereby adopted                     , 2006 subject to approval by the stockholders of the Company (the date of such approval, the “Effective Date”).

      1.2     Purpose. The purpose of the Plan is to advance the interests of the Participating Company Group and its stockholders by providing an incentive to attract and retain the best qualified personnel to perform services for the Participating Company Group, by motivating such persons to contribute to the growth and profitability of the Participating Company Group, by aligning their interests with interests of the Company’s stockholders, and by rewarding such persons for their services by tying a significant portion of their total compensation package to the success of the Company. The Plan seeks to achieve this purpose by providing for Awards in the form of Options, Stock Appreciation Rights, Restricted Stock Awards, Performance Shares, Performance Units, Restricted Stock Units, Deferred Compensation Awards and other Stock-Based Awards as described below.

      1.3     Term of Plan. The Plan shall continue in effect until the earlier of its termination by the Board or the date on which all of the shares of Stock available for issuance under the Plan have been issued and all restrictions on such shares under the terms of the Plan and the agreements evidencing Awards granted under the Plan have lapsed. However, Awards shall not be granted later than ten (10) years from the Effective Date. The Company intends that the Plan comply with Section 409A of the Code (including any amendments to or replacements of such section), and the Plan shall be so construed.

2.     Definitions and Construction.

      2.1     Definitions. Whenever used herein, the following terms shall have their respective meanings set forth below:

      2.2     Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of the Plan. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

3. Administration.

      3.1     Administration by the Committee. The Plan shall be administered by the Committee. All questions of interpretation of the Plan or of any Award shall be determined by the Committee, and such determinations shall be final and binding upon all persons having an interest in the Plan or such Award.

      3.2     Authority of Officers. Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, determination or election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, determination or election.

      3.3     Administration with Respect to Insiders. With respect to participation by Insiders in the Plan, at any time that any class of equity security of the Company is registered pursuant to Section 12 of the Exchange Act, the Plan shall be administered in compliance with the requirements, if any, of Rule 16b-3.

      3.4     Committee Complying with Section 162(m). While the Company is a “publicly held corporation” within the meaning of Section 162(m), the Board may establish a Committee of “outside directors” within the meaning of Section 162(m) to approve the grant of any Award which might reasonably be

anticipated to result in the payment of employee remuneration that would otherwise exceed the limit on employee remuneration deductible for income tax purposes pursuant to Section 162(m).

      3.5     Powers of the Committee. In addition to any other powers set forth in the Plan and subject to the provisions of the Plan, the Committee shall have the full and final power and authority, in its discretion:

      3.6     Indemnification. In addition to such other rights of indemnification as they may have as members of the Board or the Committee or as officers or employees of the Participating Company Group, members of the Board or the Committee and any officers or employees of the Participating Company Group to whom authority to act for the Board, the Committee or the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same.

      3.7     Arbitration. Any dispute or claim concerning any Awards granted (or not granted) pursuant to this Plan and any other disputes or claims relating to or arising out of the Plan shall be fully, finally and exclusively resolved by binding arbitration conducted pursuant to the Commercial Arbitration Rules of the American Arbitration Association. By accepting an Award, Participants and the Company waive their respective rights to have any such disputes or claims tried by a judge or jury.

      3.8     Repricing Prohibited. Without the affirmative vote of holders of a majority of the shares of Stock cast in person or by proxy at a meeting of the stockholders of the Company at which a quorum representing a majority of all outstanding shares of Stock is present or represented by proxy, the Committee shall not approve a program providing for either (a) the cancellation of outstanding Options or SARs and the grant in substitution therefore of new Options or SARs having a lower exercise price or (b) the amendment of outstanding Options or SARs to reduce the exercise price thereof. This paragraph shall not be construed to apply to the issuance or assumption of an Award in a transaction to which Code section 424(a) applies, within the meaning of Section 424 of the Code.

      4.1     Maximum Number of Shares Issuable. Subject to adjustment as provided in Section 4.2, the maximum aggregate number of shares of Stock that may be issued under the Plan shall be [                    (                    )] and shall consist of authorized but unissued or reacquired shares of Stock or any combination thereof. If an outstanding Award for any reason expires or is terminated or canceled without having been exercised or settled in full, or if shares of Stock acquired pursuant to an Award subject to forfeiture or repurchase are forfeited or repurchased by the Company, the shares of Stock allocable to the terminated portion of such Award or such forfeited or repurchased shares of Stock shall again be available for issuance under the Plan. Shares of Stock shall not be deemed to have been issued pursuant to the Plan (a) with respect to any portion of an Award that is settled in cash or (b) to the extent such shares are withheld or reacquired by the Company in satisfaction of tax withholding obligations pursuant to Section 15.2. Upon payment in shares of Stock pursuant to the exercise of an SAR, the number of shares available for issuance under the Plan shall be reduced only by the number of shares actually issued in such payment. If the exercise price of an Option is paid by tender to the Company, or attestation to the ownership, of shares of Stock owned by the Participant, or by means of a Net-Exercise, the number of shares available for issuance under the Plan shall be reduced only by the net number of shares for which the Option is exercised.

      4.2     Adjustments for Changes in Capital Structure. Subject to any required action by the stockholders of the Company, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate adjustments shall be made in the number and kind of shares subject to the Plan and to any outstanding Awards, in the Award limits set forth in Section 5.4, and in the exercise or purchase price per share under any outstanding Award in order to prevent dilution or enlargement of Participants’ rights under the Plan. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as “effected without receipt of consideration by the Company.” If a majority of the shares which are of the same class as the shares that are subject to outstanding Awards are exchanged for, converted into, or otherwise become (whether or not pursuant to an Ownership Change Event) shares of another corporation (the “New Shares”), the Committee may unilaterally amend the outstanding Options to provide that such Options are exercisable for New Shares. In the event of any such amendment, the number of shares subject to, and the exercise price per share of, the outstanding Awards shall be adjusted in a fair and equitable manner as determined by the Board, in its discretion. Any fractional share resulting from an adjustment pursuant to this Section 4.2 shall be rounded down to the nearest whole number. The Committee in its sole discretion, may also make such adjustments in the terms of any Award to reflect, or related to, such changes in the capital structure of the Company or distributions as it deems appropriate, including modification of Performance Goals, Performance Award Formulas and Performance Periods. The adjustments determined by the Committee pursuant to this Section 4.2 shall be final, binding and conclusive.

      5.1 Persons Eligible for Awards. Awards may be granted only to Employees, Consultants and Directors. For purposes of the foregoing sentence, “Employees,” “Consultants“and “Directors” shall include prospective Employees, prospective Consultants and prospective Directors to whom Awards are offered to be granted in connection with written offers of an employment or other service relationship with the Participating Company Group; provided, however, that no Stock subject to any such Award shall vest, become exercisable or be issued prior to the date on which such person commences Service.

      5.2 Participation. Awards other than Nonemployee Director Awards are granted solely at the discretion of the Committee. Eligible persons may be granted more than one Award. However, eligibility in accordance with this Section shall not entitle any person to be granted an Award, or, having been granted an Award, to be granted an additional Award.

      5.3 Incentive Stock Option Limitations.

      5.4     Award Limits.

      (a) Maximum Number of Shares Issuable Pursuant to Incentive Stock Options. Subject to adjustment as provided in Section 4.2, the maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to the exercise of Incentive Stock Options shall not exceed                     (                    ) shares. The maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to all Awards other than Incentive Stock Options shall be the number of shares determined in accordance with Section 4.1, subject to adjustment as provided in Section 4.2 and further subject to the limitation set forth in Section 5.4(b) below.

      (b) Aggregate Limit on Full Value Awards. Subject to adjustment as provided in Section 4.2, in no event shall more than [                    (                    )] shares in the aggregate be issued under the Plan pursuant to the exercise or settlement of Restricted Stock Awards, Restricted Stock Unit Awards and Performance Awards (“Full Value Awards”). Except with respect to a maximum of [ (                    )] shares, any Full Value Awards which vest on the basis of the Participant’s continued Service shall not provide for vesting which is any more rapid than annual pro rata vesting over a three (3) year period and any Full Value Awards which vest upon the attainment of Performance Goals shall provide for a Performance Period of at least twelve (12) months.

      (c) Section 162(m) Award Limits. The following limits shall apply to the grant of any Award if, at the time of grant, the Company is a “publicly held corporation” within the meaning of Section 162(m).

      Options shall be evidenced by Award Agreements specifying the number of shares of Stock covered thereby, in such form as the Committee shall from time to time establish. No Option or purported Option shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award

Agreement. Award Agreements evidencing Options may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

      6.1     Exercise Price. The exercise price for each Option shall be established in the discretion of the Committee; provided, however, that (a) the exercise price per share shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option and (b) no Incentive Stock Option granted to a Ten Percent Owner shall have an exercise price per share less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option. Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an exercise price lower than the minimum exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another option in a manner qualifying under the provisions of Section 424(a) of the Code.

      6.2     Exercisability and Term of Options.

      (a) Option Vesting and Exercisability. Options shall be exercisable at such time or times, or upon such event or events, and subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Committee and set forth in the Award Agreement evidencing such Option; provided, however, that (a) no Option shall be exercisable after the expiration of ten (10) years after the effective date of grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent Owner shall be exercisable after the expiration of five (5) years after the effective date of grant of such Option, (c) no Option shall become fully vested in a period of less than three (3) years from the date of grant, other than in connection with a termination of Service or a Change in Control or in the case of an Option granted to a Nonemployee Director, and (d) no Option offered or granted to a prospective Employee, prospective Consultant or prospective Director may become exercisable prior to the date on which such person commences Service. Subject to the foregoing, unless otherwise specified by the Committee in the grant of an Option, any Option granted hereunder shall terminate ten (10) years after the effective date of grant of the Option, unless earlier terminated in accordance with its provisions, or the terms of the Plan.

      (b) Participant Responsibility for Exercise of Option. Each Participant is responsible for taking any and all actions as may be required to exercise any Option in a timely manner, and for properly executing any documents as may be required for the exercise of an Option in accordance with such rules and procedures as may be established from time to time. By signing an Option Agreement each Participant acknowledges that information regarding the procedures and requirements for the exercise of any Option is available upon such Participant’s request. The Company shall have no duty or obligation to notify any Participant of the expiration date of any Option.

      6.3     Payment of Exercise Price.

      (a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the exercise price for the number of shares of Stock being purchased pursuant to any Option shall be made (i) in cash, by check or in cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of shares of Stock owned by the Participant having a Fair Market Value not less than the exercise price, (iii) provided that the Participant is an Employee, and not an Officer or Director (unless otherwise not prohibited by law, including, without limitation, any regulation promulgated by the Board of Governors of the Federal Reserve System) and in the Company’s sole and absolute discretion at the time the Option is exercised, by delivery of the Participant’s promissory note in a form approved by the Company for the aggregate exercise price, provided that, if the Company is incorporated in the State of Delaware, the Participant shall pay in cash that portion of the aggregate exercise price not less than the par value of the shares being acquired, (iv) by such other consideration as may be approved by the Committee from time to time to the extent permitted by applicable law, or (v) by any combination thereof. The Committee may at any time or from time to time grant Options which do not permit all of the foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration.

      (b) Limitations on Forms of Consideration.

      6.4     Effect of Termination of Service.

      (c) Extension if Participant Subject to Section 16(b). Notwithstanding the foregoing, if a sale within the applicable time periods of shares acquired upon the exercise of the Option would subject the Participant to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Participant would no longer be subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Participant’s termination of Service, or (iii) the Option Expiration Date.

      6.5     Transferability of Options. During the lifetime of the Participant, an Option shall be exercisable only by the Participant or the Participant’s guardian or legal representative. Prior to the issuance of shares of Stock upon the exercise of an Option, the Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Notwithstanding the foregoing, to the extent permitted by the Committee, in its discretion, and set forth in the Award Agreement evidencing such Option, a Nonstatutory Stock Option shall be assignable or transferable subject to the applicable limitations, if any, described in the General Instructions to Form S-8 Registration Statement under the Securities Act.

      Stock Appreciation Rights shall be evidenced by Award Agreements specifying the number of shares of Stock subject to the Award, in such form as the Committee shall from time to time establish. No SAR or purported SAR shall be a valid and binding obligation of the Company unless evidenced by a fully executed

Award Agreement. Award Agreements evidencing SARs may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

      7.1     Types of SARs Authorized. SARs may be granted in tandem with all or any portion of a related Option (a “Tandem SAR”) or may be granted independently of any Option (a “Freestanding SAR”). A Tandem SAR may be granted either concurrently with the grant of the related Option or at any time thereafter prior to the complete exercise, termination, expiration or cancellation of such related Option.

      7.2     Exercise Price. The exercise price for each SAR shall be established in the discretion of the Committee; provided, however, that (a) the exercise price per share subject to a Tandem SAR shall be the exercise price per share under the related Option and (b) the exercise price per share subject to a Freestanding SAR shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the SAR.

      7.3     Exercisability and Term of SARs.

      (a) Tandem SARs. Tandem SARs shall be exercisable only at the time and to the extent, and only to the extent, that the related Option is exercisable, subject to such provisions as the Committee may specify where the Tandem SAR is granted with respect to less than the full number of shares of Stock subject to the related Option.

      (b) Freestanding SARs. Freestanding SARs shall be exercisable at such time or times, or upon such event or events, and subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Committee and set forth in the Award Agreement evidencing such SAR; provided, however, that no Freestanding SAR shall be exercisable after the expiration of ten (10) years after the effective date of grant of such SAR.

      No SAR shall become fully vested in a period of less than three (3) years from the date of grant, other than in connection with a termination of Service or a Change in Control or the case of an SAR granted to a Nonemployee Director.

      7.4     Deemed Exercise of SARs. If, on the date on which an SAR would otherwise terminate or expire, the SAR by its terms remains exercisable immediately prior to such termination or expiration and, if so exercised, would result in a payment to the holder of such SAR, then any portion of such SAR which has not previously been exercised shall automatically be deemed to be exercised as of such date with respect to such portion.

      7.5     Effect of Termination of Service. Subject to earlier termination of the SAR as otherwise provided herein and unless otherwise provided by the Committee in the grant of an SAR and set forth in the Award Agreement, an SAR shall be exercisable after a Participant’s termination of Service only as provided in the Award Agreement.

      7.6     Nontransferability of SARs. During the lifetime of the Participant, an SAR shall be exercisable only by the Participant or the Participant’s guardian or legal representative. Prior to the exercise of an SAR, the SAR shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution.

      Restricted Stock Awards shall be evidenced by Award Agreements specifying the number of shares of Stock subject to the Award, in such form as the Committee shall from time to time establish. No Restricted Stock Award or purported Restricted Stock Award shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing Restricted Stock

Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

      8.1     Types of Restricted Stock Awards Authorized. Restricted Stock Awards may or may not require the payment of cash compensation for the stock. Restricted Stock Awards may be granted upon such conditions as the Committee shall determine, including, without limitation, upon the attainment of one or more Performance Goals described in Section 9.4. If either the grant of a Restricted Stock Award or the lapsing of the Restriction Period is to be contingent upon the attainment of one or more Performance Goals, the Committee shall follow procedures substantially equivalent to those set forth in Sections 9.3 through 9.5(a).

      8.2     Purchase Price. The purchase price, if any, for shares of Stock issuable under each Restricted Stock Award and the means of payment shall be established by the Committee in its discretion.

      8.3     Purchase Period. A Restricted Stock Award requiring the payment of cash consideration shall be exercisable within a period established by the Committee; provided, however, that no Restricted Stock Award granted to a prospective Employee, prospective Consultant or prospective Director may become exercisable prior to the date on which such person commences Service.

      8.4     Vesting and Restrictions on Transfer. Shares issued pursuant to any Restricted Stock Award may or may not be made subject to Vesting Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, including, without limitation, Performance Goals as described in Section 9.4, as shall be established by the Committee and set forth in the Award Agreement evidencing such Award. During any Restriction Period in which shares acquired pursuant to a Restricted Stock Award remain subject to Vesting Conditions, such shares may not be sold, exchanged, transferred, pledged, assigned or otherwise disposed of other than as provided in the Award Agreement or as provided in Section 8.7. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder.

      8.5     Voting Rights; Dividends and Distributions. Except as provided in this Section, Section 8.4 and any Award Agreement, during the Restriction Period applicable to shares subject to a Restricted Stock Award, the Participant shall have all of the rights of a stockholder of the Company holding shares of Stock, including the right to vote such shares and to receive all dividends and other distributions paid with respect to such shares. However, in the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.2, any and all new, substituted or additional securities or other property (other than normal cash dividends) to which the Participant is entitled by reason of the Participant’s Restricted Stock Award shall be immediately subject to the same Vesting Conditions as the shares subject to the Restricted Stock Award with respect to which such dividends or distributions were paid or adjustments were made.

      8.6     Effect of Termination of Service. Unless otherwise provided by the Committee in the grant of a Restricted Stock Award and set forth in the Award Agreement, if a Participant’s Service terminates for any reason, whether voluntary or involuntary (including the Participant’s death or disability), then the Participant shall forfeit to the Company any shares acquired by the Participant pursuant to a Restricted Stock Award which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service in exchange for the payment of the purchase price, if any, paid by the Participant. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company.

      8.7     Nontransferability of Restricted Stock Award Rights. Prior to the issuance of shares of Stock pursuant to a Restricted Stock Award, rights to acquire such shares shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or the laws of descent and distribution. All rights with respect to a Restricted Stock Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or legal representative.

      Performance Awards shall be evidenced by Award Agreements in such form as the Committee shall from time to time establish. No Performance Award or purported Performance Award shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing Performance Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

      9.1     Types of Performance Awards Authorized. Performance Awards may be in the form of either Performance Shares or Performance Units. Each Award Agreement evidencing a Performance Award shall specify the number of Performance Shares or Performance Units subject thereto, the Performance Award Formula, the Performance Goal(s) and Performance Period applicable to the Award, and the other terms, conditions and restrictions of the Award.

      9.2     Initial Value of Performance Shares and Performance Units. Unless otherwise provided by the Committee in granting a Performance Award, each Performance Share shall have an initial value equal to the Fair Market Value of one (1) share of Stock, subject to adjustment as provided in Section 4.2, on the effective date of grant of the Performance Share. Each Performance Unit shall have an initial value determined by the Committee. The final value payable to the Participant in settlement of a Performance Award determined on the basis of the applicable Performance Award Formula will depend on the extent to which Performance Goals established by the Committee are attained within the applicable Performance Period established by the Committee.

      9.3     Establishment of Performance Period, Performance Goals and Performance Award Formula. In granting each Performance Award, the Committee shall establish in writing the applicable Performance Period, Performance Award Formula and one or more Performance Goals which, when measured at the end of the Performance Period, shall determine on the basis of the Performance Award Formula the final value of the Performance Award to be paid to the Participant. To the extent compliance with the requirements under Section 162(m) with respect to “performance-based compensation” is desired, the Committee shall establish the Performance Goal(s) and Performance Award Formula applicable to each Performance Award no later than the earlier of (a) the date ninety (90) days after the commencement of the applicable Performance Period or (b) the date on which 25% of the Performance Period has elapsed, and, in any event, at a time when the outcome of the Performance Goals remains substantially uncertain. Once established, the Performance Goals and Performance Award Formula shall not be changed during the Performance Period. The Company shall notify each Participant granted a Performance Award of the terms of such Award, including the Performance Period, Performance Goal(s) and Performance Award Formula.

      9.4     Measurement of Performance Goals. Performance Goals shall be established by the Committee on the basis of targets to be attained (“Performance Targets”) with respect to one or more measures of business or financial performance (each, a “Performance Measure”), subject to the following:

      (b) Performance Targets. Performance Targets may include a minimum, maximum, target level and intermediate levels of performance, with the final value of a Performance Award determined under the applicable Performance Award Formula by the level attained during the applicable Performance Period. A Performance Target may be stated as an absolute value or as a value determined relative to a standard selected by the Committee.

      9.5     Settlement of Performance Awards.

      (c) Payment in Settlement of Performance Awards. As soon as practicable following the Committee’s determination and certification in accordance with Sections 9.5(a) and (b), payment shall be made to each eligible Participant (or such Participant’s legal representative or other person who acquired the right to receive such payment by reason of the Participant’s death) of the final value of the Participant’s Performance Award. Payment of such amount shall be made in cash in a lump sum or in installments, shares of Stock (either fully vested or subject to vesting), or a combination thereof, as determined by the Committee.

      9.6     Voting Rights; Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with respect to shares of Stock represented by Performance Share Awards until the date of the issuance of such shares, if any (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). However, the Committee, in its discretion, may provide in the Award Agreement evidencing any Performance Share Award that the Participant shall be entitled to receive Dividend Equivalents with respect to the payment of cash dividends on Stock having a record date prior to the date on which the Performance Shares are settled or forfeited. Such Dividend Equivalents, if any, shall be credited to the Participant in the form of additional whole Performance Shares as of the date of payment of such cash dividends on Stock. The number of additional Performance Shares (rounded to the nearest whole number) to be so credited shall be determined by dividing (a) the amount of cash dividends paid on such date

with respect to the number of shares of Stock represented by the Performance Shares previously credited to the Participant by (b) the Fair Market Value per share of Stock on such date. Dividend Equivalents may be paid currently or may be accumulated and paid to the extent that Performance Shares become nonforfeitable, as determined by the Committee. Settlement of Dividend Equivalents may be made in cash, shares of Stock, or a combination thereof as determined by the Committee, and may be paid on the same basis as settlement of the related Performance Share as provided in Section 9.5. Dividend Equivalents shall not be paid with respect to Performance Units. In the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.2, appropriate adjustments shall be made in the Participant’s Performance Share Award so that it represents the right to receive upon settlement any and all new, substituted or additional securities or other property (other than normal cash dividends) to which the Participant would entitled by reason of the shares of Stock issuable upon settlement of the Performance Share Award, and all such new, substituted or additional securities or other property shall be immediately subject to the same Performance Goals as are applicable to the Award.

      9.7     Effect of Termination of Service. Unless otherwise provided by the Committee in the grant of a Performance Award and set forth in the Award Agreement, the effect of a Participant’s termination of Service on the Performance Award shall be as follows:

      9.8     Nontransferability of Performance Awards. Prior to settlement in accordance with the provisions of the Plan, no Performance Award shall be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. All rights with respect to a Performance Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or legal representative.

10. Terms and Conditions of Restricted Stock Unit Awards.

      Restricted Stock Unit Awards shall be evidenced by Award Agreements specifying the number of Restricted Stock Units subject to the Award, in such form as the Committee shall from time to time establish. No Restricted Stock Unit Award or purported Restricted Stock Unit Award shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing Restricted Stock Units may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

      10.1     Grant of Restricted Stock Unit Awards. Restricted Stock Unit Awards may be granted upon such conditions as the Committee shall determine, including, without limitation, upon the attainment of one or more Performance Goals described in Section 9.4. If either the grant of a Restricted Stock Unit Award or the Vesting Conditions with respect to such Award is to be contingent upon the attainment of one or more Performance Goals, the Committee shall follow procedures substantially equivalent to those set forth in Sections 9.3 through 9.5(a).

      10.2     Vesting. Restricted Stock Units may or may not be made subject to Vesting Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, including, without limitation, Performance Goals as described in Section 9.4, as shall be established by the Committee and set forth in the Award Agreement evidencing such Award.

      10.3     Voting Rights, Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with respect to shares of Stock represented by Restricted Stock Units until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). However, the Committee, in its discretion, may provide in the Award Agreement evidencing any Restricted Stock Unit Award that the Participant shall be entitled to receive Dividend Equivalents with respect to the payment of cash dividends on Stock having a record date prior to the date on which Restricted Stock Units held by such Participant are settled. Such Dividend Equivalents, if any, shall be paid by crediting the Participant with additional whole Restricted Stock Units as of the date of payment of such cash dividends on Stock. The number of additional Restricted Stock Units (rounded to the nearest whole number) to be so credited shall be determined by dividing (a) the amount of cash dividends paid on such date with respect to the number of shares of Stock represented by the Restricted Stock Units previously credited to the Participant by (b) the Fair Market Value per share of Stock on such date. Such additional Restricted Stock Units shall be subject to the same terms and conditions and shall be settled in the same manner and at the same time (or as soon thereafter as practicable) as the Restricted Stock Units originally subject to the Restricted Stock Unit Award. In the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.2, appropriate adjustments shall be made in the Participant’s Restricted Stock Unit Award so that it represents the right to receive upon settlement any and all new, substituted or additional securities or other property (other than normal cash dividends) to which the Participant would entitled by reason of the shares of Stock issuable upon settlement of the Award, and all such new, substituted or additional securities or other property shall be immediately subject to the same Vesting Conditions as are applicable to the Award.

      10.4     Effect of Termination of Service. Unless otherwise provided by the Committee in the grant of a Restricted Stock Unit Award and set forth in the Award Agreement, if a Participant’s Service terminates for any reason, whether voluntary or involuntary (including the Participant’s death or disability), then the Participant shall forfeit to the Company any Restricted Stock Units pursuant to the Award which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service.

      10.5     Settlement of Restricted Stock Unit Awards. The Company shall issue to a Participant on the date on which Restricted Stock Units subject to the Participant’s Restricted Stock Unit Award vest or on such other date determined by the Committee, in its discretion, and set forth in the Award Agreement one (1) share of Stock (and/or any other new, substituted or additional securities or other property pursuant to an adjustment described in Section 10.3) for each Restricted Stock Unit then becoming vested or otherwise to be settled on such date, subject to the withholding of applicable taxes. Notwithstanding the foregoing, if permitted by the Committee and set forth in the Award Agreement, the Participant may elect in accordance with terms specified in the Award Agreement to defer receipt of all or any portion of the shares of Stock or other property otherwise issuable to the Participant pursuant to this Section.

      10.6     Nontransferability of Restricted Stock Unit Awards. Prior to the issuance of shares of Stock in settlement of a Restricted Stock Unit Award, the Award shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. All rights with respect to a Restricted Stock Unit Award granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or legal representative.

      11. Deferred Compensation Awards.

      11.1     Establishment of Deferred Compensation Award Programs. This Section 11 shall not be effective unless and until the Committee determines to establish a program pursuant to this Section. The Committee,

in its discretion and upon such terms and conditions as it may determine, may establish one or more programs pursuant to the Plan under which:

      11.2     Terms and Conditions of Deferred Compensation Awards. Deferred Compensation Awards granted pursuant to this Section 11 shall be evidenced by Award Agreements in such form as the Committee shall from time to time establish. No such Deferred Compensation Award or purported Deferred Compensation Award shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing Deferred Compensation Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

12.     Other Stock-Based Awards.

      In addition to the Awards set forth in Sections 6 through 11 above, the Committee, in its sole discretion, may carry out the purpose of this Plan by awarding Stock-Based Awards as it determines to be in the best interests of the Company and subject to such other terms and conditions as it deems necessary and appropriate.

13.     Effect of Change in Control on Options and SARs.

      13.1     Accelerated Vesting. The Committee, in its sole discretion, may provide in any Award Agreement or, in the event of a Change in Control, may take such actions as it deems appropriate to provide for the acceleration of the exercisability and vesting in connection with such Change in Control of any or all outstanding Options and SARs and shares acquired upon the exercise of such Options and SARs upon such conditions and to such extent as the Committee shall determine. The previous sentence notwithstanding such acceleration shall not occur to the extent an Option or SAR is assumed or substituted with a substantially similar Award in connection with a Change in Control.

      13.2     Assumption or Substitution. In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the “Acquiring Corporation”), may, without the consent of the Participant, either assume the Company’s rights and obligations under outstanding Options and SARs or substitute for outstanding Options and SARs substantially equivalent options or stock appreciation rights for the Acquiring Corporation’s stock. Any Options or SARs which are neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control shall terminate and cease to be outstanding effective as of the date of the Change in Control. Notwithstanding the foregoing, shares acquired upon exercise of an Option or SAR prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of the Award Agreement evidencing such Award except as otherwise provided in such Award Agreement. Furthermore, notwithstanding the foregoing, if the corporation the stock of which is subject to the outstanding Options or SARs immediately prior to an Ownership Change Event described in Section 2.1(y)(i) constituting a Change in Control is the surviving or continuing corporation and immediately after such Ownership Change Event less than fifty percent (50%) of the total combined voting power of its voting stock is held by another corporation or by other corporations that are members of an affiliated group within the meaning of Section 1504(a) of the Code without regard to the provisions of Section 1504(b) of the Code, the outstanding Options and SARs shall not terminate unless the Board otherwise provides in its discretion.

      13.3     Effect of Change in Control on Restricted Stock and Other Type of Awards. The Committee may, in its discretion, provide in any Award Agreement evidencing a Restricted Stock or Other Type of Award

that, in the event of a Change in Control, the lapsing of any applicable Vesting Condition, Restriction Period or Performance Goal applicable to the shares subject to such Award held by a Participant whose Service has not terminated prior to the Change in Control shall be accelerated and/or waived effective immediately prior to the consummation of the Change in Control to such extent as specified in such Award Agreement; provided, however, that such acceleration or waiver shall not occur to the extent an Award is assumed or substituted with a substantially equivalent Award in connection with the Change in Control. Any acceleration, waiver or the lapsing of any restriction that was permissible solely by reason of this Section 13.3 and the provisions of such Award Agreement shall be conditioned upon the consummation of the Change in Control.

14.     Compliance with Securities Law.

      The grant of Awards and the issuance of shares of Stock pursuant to any Award shall be subject to compliance with all applicable requirements of federal, state and foreign law with respect to such securities and the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, no Award may be exercised or shares issued pursuant to an Award unless (a) a registration statement under the Securities Act shall at the time of such exercise or issuance be in effect with respect to the shares issuable pursuant to the Award or (b) in the opinion of legal counsel to the Company, the shares issuable pursuant to the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to issuance of any Stock, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

15.     Tax Withholding.

      15.1     Tax Withholding in General. The Company shall have the right to deduct from any and all payments made under the Plan, or to require the Participant, through payroll withholding, cash payment or otherwise, including by means of a Cashless Exercise or Net Exercise of an Option, to make adequate provision for, the federal, state, local and foreign taxes, if any, required by law to be withheld by the Participating Company Group with respect to an Award or the shares acquired pursuant thereto. The Company shall have no obligation to deliver shares of Stock, to release shares of Stock from an escrow established pursuant to an Award Agreement, or to make any payment in cash under the Plan until the Participating Company Group’s tax withholding obligations have been satisfied by the Participant.

      15.2     Withholding in Shares. The Company shall have the right, but not the obligation, to deduct from the shares of Stock issuable to a Participant upon the exercise or settlement of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair Market Value, as determined by the Company, equal to all or any part of the tax withholding obligations of the Participating Company Group. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall not exceed the amount determined by the applicable minimum statutory withholding rates.

      The Board or the Committee may amend, suspend or terminate the Plan at any time. However, without the approval of the Company’s stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.2), (b) no change in the class of persons eligible to receive Incentive Stock Options, and (c) no other amendment of the Plan that would require approval of the Company’s stockholders under any applicable law, regulation or rule. No amendment, suspension or termination of the Plan shall affect any then outstanding Award unless expressly provided by the Board or the Committee. In any event, no amendment, suspension or termination of

the Plan may adversely affect any then outstanding Award without the consent of the Participant unless necessary to comply with any applicable law, regulation or rule.

      17.1     Repurchase Rights. Shares issued under the Plan may be subject to one or more repurchase options, or other conditions and restrictions as determined by the Committee in its discretion at the time the Award is granted. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such transfer restrictions.

      17.2     Provision of Information. Each Participant shall be given access to information concerning the Company equivalent to that information generally made available to the Company’s common stockholders.

      17.3     Rights as Employee, Consultant or Director. No person, even though eligible pursuant to Section 5, shall have a right to be selected as a Participant, or, having been so selected, to be selected again as a Participant. Nothing in the Plan or any Award granted under the Plan shall confer on any Participant a right to remain an Employee, Consultant or Director or interfere with or limit in any way any right of a Participating Company to terminate the Participant’s Service at any time. To the extent that an Employee of a Participating Company other than the Company receives an Award under the Plan, that Award shall in no event be understood or interpreted to mean that the Company is the Employee’s employer or that the Employee has an employment relationship with the Company.

      17.4     Rights as a Stockholder. A Participant shall have no rights as a stockholder with respect to any shares covered by an Award until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such shares are issued, except as provided in Section 4.2 or another provision of the Plan.

      17.5     Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise or settlement of any Award.

      17.6     Severability. If any one or more of the provisions (or any part thereof) of this Plan shall be held invalid, illegal or unenforceable in any respect, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions (or any part thereof) of the Plan shall not in any way be affected or impaired thereby.

      17.7     Beneficiary Designation. Subject to local laws and procedures, each Participant may file with the Company a written designation of a beneficiary who is to receive any benefit under the Plan to which the Participant is entitled in the event of such Participant’s death before he or she receives any or all of such benefit. Each designation will revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. If a married Participant designates a beneficiary other than the Participant’s spouse, the effectiveness of such designation may be subject to the consent of the Participant’s spouse. If a Participant dies without an effective designation of a beneficiary who is living at the time of the Participant’s death, the Company will pay any remaining unpaid benefits to the Participant’s legal representative.

      17.8     Unfunded Obligation. Participants shall have the status of general unsecured creditors of the Company. Any amounts payable to Participants pursuant to the Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974. No Participating Company shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may

make to fulfill its payment obligations hereunder. Any investments or the creation or maintenance of any trust or any Participant account shall not create or constitute a trust or fiduciary relationship between the Committee or any Participating Company and a Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant’s creditors in any assets of any Participating Company. The Participants shall have no claim against any Participating Company for any changes in the value of any assets which may be invested or reinvested by the Company with respect to the Plan. Each Participating Company shall be responsible for making benefit payments pursuant to the Plan on behalf of its Participants or for reimbursing the Company for the cost of such payments, as determined by the Company in its sole discretion. In the event the respective Participating Company fails to make such payment or reimbursement, a Participant’s (or other individual’s) sole recourse shall be against the respective Participating Company, and not against the Company. A Participant’s acceptance of an Award pursuant to the Plan shall constitute agreement with this provision.
