Forward Looking Statements This presentation contains forward-looking statements and information that are based on Enterprise’s beliefs 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,” “goal,” “forecast,” “intend,” “could,” “believe,” “may,” and similar expressions and statements regarding the contemplated transaction and 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 NGLs 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; Operating cash flows from our capital projects may not be immediate; 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. Enterprise has no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Use of Non-GAAP Financial Measures This presentation utilizes the Non-GAAP financial measures of Gross Operating Margin, EBITDA, Distributable Cash Flow and Consolidated EBITDA. In general, we define Gross Operating Margin as operating income before (i) depreciation, amortization and accretion expense; (ii) operating lease expense for which we do not have the payment obligation; (iii) gains and losses on the sale of assets and (iv) general and administrative expenses. We define EBITDA as net income or loss before interest; provision for income taxes; and depreciation, amortization and accretion expense. In general, we define Distributable Cash Flow as net income or loss plus (i) depreciation, amortization and accretion expense; (ii) operating lease expense for which we do not have the payment obligation; (iii) cash distributions received from unconsolidated affiliates less equity in the earnings of such affiliates; (iv) the subtraction of sustaining capital expenditures; (v) gains and losses on the sale of assets; (vi) cash proceeds from the sale of assets or return of investment from unconsolidated affiliates; (vii) gains or losses on monetization of financial instruments recorded in Accumulated Other Comprehensive Income less related amortization of such amount to earnings; (viii) transition support payments received from El Paso related to the GTM Merger and (ix) the addition of losses or subtraction of gains related to other miscellaneous non-cash amounts affecting net income for the period. Distributable Cash Flow is a significant liquidity metric used by our senior management to compare basic cash flows generated by us to the cash distributions we expect to pay partners. Distributable Cash Flow is also an important Non-GAAP financial measure for our limited partners since it serves as an indicator of our success in providing a cash return on investment. Distributable Cash Flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships such as ours because the value of a partnership unit is in part measured by its yield (which in turn is based on the amount of cash distributions a partnership pays to a unit holder). The GAAP measure most directly comparable to Distributable Cash Flow is net cash provided by operating activities. This presentation also includes references to credit leverage ratios that utilize Consolidated EBITDA, which is a term defined in the $1.25 billion revolving credit facility of Enterprise Products Operating L.P. These credit ratios are used by certain of our lenders to evaluate our ability to support debt service. The GAAP measure most directly comparable to Consolidated EBITDA is net cash provided by operating activities. Please see Slides 29 through 33 for our calculations of these Non-GAAP financial measures along with the appropriate reconciliations.

Overview Enterprise Products Partners L.P. (“EPD”) is one of the largest publicly traded energy partnerships serving producers and consumers of natural gas, natural gas liquids (NGLs) and crude oil Enterprise value of approximately $17 billion Market capitalization of over $12 billion Ranked 183rd on Fortune 500 list Only integrated North American midstream network that includes natural gas, NGL and crude oil gathering, transportation, processing, fractionation, storage and import / export services

Key Investment Considerations Strategically located assets serving the most prolific supply basins and largest consuming regions of natural gas, NGLs and crude oil in the United States Leading business positions across energy value chain Over 90% gross operating margin from diversified fee-based assets Visible cash flow growth from approximately $2 billion of growth projects expected to be completed within next 12 months 25% GP split cap reduces cash paid to GP, lowers cost of capital and enhances returns to LP’s, compared to MLPs with higher splits (e.g., 50%) Experienced management team with substantial ownership

Management’s Interest Aligned with Limited Partners EPCO has consistently supported growth in EPD Purchased $53 million of new equity in August 2006, and approx. $450 million since IPO Capped GP’s incentive split at 25% for no consideration Contributed half of GTM GP to EPD for no consideration - approx. $460 million in value Value of EPCO’s holdings in EPD and EPE units - approx. $6.8 billion
