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; andThe 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.

Non-GAAP Financial Measures

This presentation utilizes the Non-GAAP financial measures of Gross Operating Margin 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. The GAAP measure most directly comparable to Gross Operating Margin is net cash flows provided by operating activities.This presentation includes references to Consolidated EBITDA, which is a term defined in the $1.25 billion revolving credit facility of Enterprise Products Operating LLC, EPD’s operating subsidiary. Consolidated EBITDA is 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 flows provided by operating activities. Please see slides 28 through 30 for our calculations of these Non-GAAP financial measures along with the appropriate reconciliations.
