FUNDAMENTALS

EPD OBSERVATIONS ON OIL PRICES Cut Existing Production: OPEC could not agree on production cuts at November 2014 meeting, with strongest members signaling no appetite to cut Slow Supply Growth: lower prices impact both OPEC, Russian and North Americansupply growth • Poorly capitalized OPEC nations and Russia rely on multinational oil company investments; lower prices and geopolitical instability in Middle East North Africa (“MENA”) will impact these investments • U.S. shale producers are cutting back on drilling; more expected in 2015; however, leasehold and drilling commitments will delay impact. Additionally, the severity of these cutbacks will be offset by continued technology enhancements and location high?grading. • U.S. crude and NGL production expected to grow in 2015 regardless of current oil prices Incremental Demand: low prices create incremental demand including Asian strategic petroleum reserve (“SPR”) • Economists estimate ?300 MBPD global demand response for each 10% decline in oil price; however, it comes with a time lag that is impacted by many factors • China and India have increased SPR over last year at higher prices and have capacity to further increase stockpiling • Low prices likely to cause some demand destruction from renewable initiatives Geopolitical Risks: low prices will have far reaching consequences on poorly capitalized nations with economies dependent on much higher oil prices

NON–GAAP RECONCILIATIONS

GROSS OPERATING MARGIN We evaluate segment performance based on the non?GAAP financial measure of gross operating margin. Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations. This measure forms the basis of our internal financial reporting and is used by our management in deciding how to allocate capital resources among business segments. The following table reconciles non?GAAP gross operating margin to operating income, which is the most directly comparable GAAP financial measure to gross operating margin (dollars in millions): For the Nine For the Twelve For the Year Ended December 31, Months Ended Months Ended 2010 2011 2012 2013 September 30, 2014 September 30, 2014 Gross operating margin by segment: NGL Pipelines & Services $ 1,732.6 $ 2,184.2 $ 2,468.5 $ 2,514.4 $2,172.4 $2,909.8 Onshore Natural Gas Pipelines & Services 527.2 675.3 775.5 789.0 618.8 805.9 Onshore Crude Oil Pipelines & Services 113.7 234.0 387.7 742.7 534.5 697.6 Offshore Pipelines & Services 297.8 228.2 173.0 146.1 120.0 148.0 Petrochemical & Refined Products Services 584.5 535.2 579.9 625.9 482.4 657.6 Other Investments (2.8) 14.82.4? ? ?Total gross operating margin (non?GAAP) 3,253.0 3,871.7 4,387.0 4,818.13,928.15,218.9 Adjustments to reconcile non?GAAP gross operating margin to GAAP operating income: Subtract depreciation, amortization and accretion expense amounts not reflected in gross operating margin(936.3)(958.7)(1,061.7)(1,148.9) (936.5) (1,233.7) Subtract impairment charges not reflected in gross operating margin (8.4)(27.8)(63.4)(92.6) (18.2) (57.5) Subtract operating lease expenses paid by EPCO not reflected in gross operating margin (0.7) (0.3)?? ? ?

ADJUSTED EBITDA Adjusted EBITDA is commonly used as a supplemental financial measure by our management and external users of our financial statements, such as investors, commercial banks, research analysts and ratings agencies to assess: (1) the financial performance of our assets without regard to financing methods, capital structures or historical cost basis; (2) the ability of our assets to generate cash sufficient to pay interest and support our indebtedness; and (3) 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 included in this presentation may not be comparable to similarly titled measures of other companies. The following table reconciles non GAAP adjusted EBITDA to net cash flows provided by operating activities, which is the most directly comparable GAAP financial measure to adjusted EBITDA (dollars in millions): For the Nine For the Twelve For the Year Ended December 31, Months Ended Months Ended 2010 2011 2012 2013 September 30, 2014 September 30, 2014 Net income (GAAP) $ 1,383.7 $ 2,088.3 $ 2,428.0 $ 2,607.1 $2,152.4 $2,858.1 Adjustments to GAAP net income to derive non GAAP Adjusted EBITDA: Subtract equity in income of unconsolidated affiliates(62.0)(46.4)(64.3)(167.3) (179.1) (220.3) Add distributions received from unconsolidated affiliates 191.9 156.4 116.7 251.6 260.7 324.7 Add interest expense, including related amortization 741.9 744.1 771.8 802.5 679.6 877.7 Add provision for or subtract benefit from income taxes, as applicable 26.1 27.2(17.2) 57.522.533.8 Add depreciation, amortization and accretion in costs and expenses 974.5 990.5 1,094.9 1,185.4 966.21,272.5 Adjusted EBITDA (non GAAP) 3,256.1 3,960.1 4,329.9 4,736.83,902.35,146.5 Adjustments to non GAAP Adjusted EBITDA to derive GAAP net cash flows provided by operating activities: Subtract interest expense, including related amortization, reflected in(741.9)(744.1)(771.8)(802.5) (679.6) (877.7) Adjusted EBITDA Add benefit from or subtract provision for income taxes reflected in Adjusted EBITDA(26.1)(27.2) 17.2(57.5) (22.5) (33.8) Subtract net gains attributable to asset sales and insurance recoveries(46.7)(155.7)(86.4)(83.3) (99.0) (113.9) Add deferred income tax expense or subtract benefit, as applicable7.9 12.1(66.2) 37.9 2.6 8.4 Add impairment charges8.4 27.8 63.4 92.618.257.5 Add or subtract the net effect of changes in operating accounts, as applicable(190.4) 266.9(582.5)(97.6) (435.8) (19.5) Add or subtract miscellaneous non cash and other amounts to reconcile non GAAP Adjusted EBITDA with GAAP net cash flows provided by operating activities 32.7 (9.4)(12.7) 39.118.236.2 Net cash flows provided by operating activities (GAAP) $ 2,300.0 $ 3,330.5 $ 2,890.9 $ 3,865.5 $2,704.4 $4,203.7 Note: Adjusted EBITDA has been presented as if EPD were Enterprise GP Holdings for all periods prior to the Holdings Merger, which was completed in November 2010.

DISTRIBUTABLE CASH FLOW Distributablecashflowisanimportant non?GAAP financial measure for our limited partners since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not we are generating cash flows at a level that can sustain or support an increase in our quarterly cash distributions. Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is, in part, measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder. The following table reconciles non?GAAP Distributable Cash Flow to net cash flows provided by operating activities, which is the most directly comparable GAAP financial measure to distributable cash flow (dollars in millions): For the Nine For the Year Ended December 31, Months Ended 2010 2011 2012 2013 September 30, 2014 Net income attributable to limited partners (GAAP) $1,266.7 $2,046.9 $2,419.9 $2,596.9 $2,127.6 Adjustments to GAAP net income attributable to limited partners to derive non?GAAP distributable cash flow: Add depreciation, amortization and accretion expenses 980.2 1,007.0 1,104.9 1,217.6 992.4 Add distributions received from unconsolidated affiliates 128.2 156.4 116.7 251.6 260.7 Subtract equity in income of unconsolidated affiliates (69.0) (46.4) (64.3)(167.3) (179.1) Subtract sustaining capital expenditures (240.3)(296.4)(366.2)(291.7) (262.0) Subtract net gains from asset sales and insurance recoveries (46.7)(155.7) (86.4) (83.3) (99.0) Add cash proceeds from asset sales and insurance recoveries 105.9 1,053.8 1,198.8 280.6 121.5 Add gains or subtract losses from the monetization of interest rate derivative instruments1.3 (23.2)(147.8)(168.8) ?
