("Enterprise" or "EPD") and those of its general partner, as well as assumptions made by and information currently available to them. When used in this presentation, words such as "anticipate," "project," "expect," "plan," "seek," "goal," "estimate," "forecast," "intend," "could," "should," "will," "believe," "may," "potential," and similar expressions and statements regarding the plans and objectives of Enterprise for future operations, are intended to identify forward-looking statements. Although Enterprise and its general partner believe that such expectations reflected in such forward-looking statements are reasonable, neither it nor its general partner can give assurances that such expectations will prove to be correct. Such statements are subject to a variety of risks, uncertainties and assumptions. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those Enterprise anticipated, estimated, projected or expected. Among the key risk factors that may have a direct bearing on Enterprise's results of operations and financial condition are: Fluctuations in oil, natural gas and NGL prices and production due to weather and other natural and economic forces; A reduction in demand for its products by the petrochemical, refining or heating industries; The effects of its debt level on its future financial and operating flexibility; A decline in the volumes of energy commodities delivered by its facilities; The failure of its credit risk management efforts to adequately protect it against customer non-payment; Actual construction and development costs could exceed forecasted amounts; The proposed merger with Enterprise GP Holdings L.P. ("EPE") may not be completed prior to the December 31, 2010 outside termination date, due to failure to obtain the required approvals by EPE unitholders and regulatory agencies, and the possibility that the anticipated benefits of the merger cannot be fully realized; Operating cash flows from our capital projects may not be immediate; National, international, regional and local economic, competitive and regulatory conditions; Terrorist attacks aimed at its facilities; and The failure to successfully integrate its operations with assets or companies, if any, that it may acquire in the future. The foregoing discussion of important factors may not be all-inclusive and Enterprise provides additional cautionary discussion of risks and uncertainties under the captions "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in its recent filings with the U.S. Securities and Exchange Commission. You should not put undue reliance on any forward-looking statements.

Eagle Ford Shale Expansion Projects

NGL Demand Growth by Petrochemical Industry

Shale Plays Drive Natural Gas Production Growth Resulting in lower natural gas prices relative to crude oil NGLs extracted from natural gas processing plants are very cost competitive compared to more costly crude oil derivatives Non-conventional / shale plays have driven significant growth in U.S. natural gas reserves and production While demand has remained relatively flat Sources: EIA

U.S. Crackers Very Competitive Globally Due to Significant Feedstock Cost Advantage Ethane has consistently become the most profitable feedstock for ethylene steam crackers versus more expensive crude oil derivatives Indicative U.S. Ethylene Cracker Profit Margin by Feedstock Making U.S. ethylene crackers among the most competitive in the world Sources: Enterprise and CMAI

U.S. Domestic Demand and Exports of Ethylene and Ethylene Derivatives Ethylene and Ethylene Derivatives Ethylene and Ethylene Derivatives Current ethane demand of 941 MBPD is being supplied by approximately 840 MBPD from gas processing plants, 45 MBPD from refinery production and 55 MBPD from inventory Given expected growth of U.S. NGL supplies and NGL cost advantage versus crude oil derivatives, there is potential for another 100 MBPD of cracker modifications Ethylene crackers have been operating in the low to mid-90% range in the second half of 2010 due to strong domestic demand and the competitive export position for ethylene derivatives US domestic ethylene demand for full year is up an estimated 5.1% over 2009 demand US ethylene equivalent exports for 1H 2010 are up 6.1% over 1H 2009 exports 2003 2004 2005 2006 2007 2008 1Q09 2Q09 3Q09 4Q09 1Q10 2Q10 3Q10 10/10/2010 Ethane 688 776 712 745 767 716 680 835 803 880 880 838 931 941 Propane 298 368 351 374 374 312 245 335 377 359 332 369 372 309 Ethane demand: 5 year average ~748 MBPD Sources: CMAI and Hodson Ethane demand for 3Q10 increased 24% compared to 5-year average

Non-GAAP Reconciliations

This presentation utilizes the Non-GAAP financial measures of Gross Operating Margin, Adjusted EBITDA and Distributable Cash Flow. In general, we define Gross Operating Margin as operating income before: (i) depreciation, amortization and accretion expense; (ii) non-cash asset impairment charges; (iii) operating lease expenses for which we do not have the payment obligation; (iv) gains and losses from asset sales and related transactions; and (v) general and administrative costs. The GAAP financial measure most directly comparable to Gross Operating Margin is operating income. In general, we define distributable cash flow as net income or loss attributable to Enterprise Products Partners L.P. adjusted for: (i) the addition of depreciation, amortization and accretion expense; (ii) the addition of operating lease expenses for which we do not have the payment obligation; (iii) the addition of cash distributions received from unconsolidated affiliates less equity in income from unconsolidated affiliates; (iv) the subtraction of sustaining capital expenditures and cash payments to settle asset retirement obligations; (v) the addition of losses or subtraction of gains from asset sales and related transactions; (vi) the addition of cash proceeds from asset sales or related transactions; (vii) the return of an investment in an unconsolidated affiliate (if any); (viii) the addition of losses or subtraction of gains on the monetization of derivative instruments recorded in accumulated other comprehensive income (loss), if any, less related amortization of such amount to earnings; (ix) the addition of transition support payments received from El Paso Corporation related to the GulfTerra merger; (x) the addition of net income attributable to the noncontrolling interest associated with the public unitholders of Duncan Energy Partners L.P., less related distributions to be paid to such holders with respect to the period of calculation; and (xi) the addition or subtraction of other miscellaneous non-cash amounts (as applicable) that affect net income or loss for the period. The GAAP measure most directly comparable to Distributable Cash Flow is net cash flows provided by operating activities. We define Adjusted EBITDA as net income or loss minus equity in income of unconsolidated affiliates, plus distributions received from unconsolidated affiliates, interest expense, provision for income taxes and depreciation, amortization and accretion expense. Adjusted EBITDA is commonly used as a supplemental financial measure by management and external users of our financial statements, such as investors, commercial banks, research analysts and rating agencies, to assess: (i) the financial performance of our assets without regard to financing methods, capital structures or historical cost basis; (ii) the ability of our assets to generate cash sufficient to pay interest and support our indebtedness; and (iii) the viability of projects and the overall rates of return on alternative investment opportunities. Since Adjusted EBITDA excludes some, but not all, items that affect net income or loss and because these measures may vary among other companies, the Adjusted EBITDA data presented in this press release may not be comparable to similarly titled measures of other companies. The GAAP measure most directly comparable to Adjusted EBITDA is net cash flows provided by operating activities. Non-GAAP Financial Measures
