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 American supply 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 indicating drilling cut backs in 2015; however, leasehold and drilling commitments will delay impact. In addition, the severity of these cutbacks will be offset by continued technology enhancements and location high-grading.

U.S. crude and NGL production will 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

ACQUISITION OF OILTANKING (OILT) OVERVIEW AND RATIONALE

On October 1, 2014, EPD acquired OILT’s GP and related IDRs, 15.9 million OILT common units and 38.9 million OILT subordinated units (which converted one-to-one to common units on November 17, 2014) for $4.41 billion of consideration consisting of $2.21 billion of cash and 54.8 million newly issued EPD common units On November 11, 2014, EPD and OILT executed merger agreement in which EPD would issue 1.3 EPD common units for each OILT common unit ($1.4 billion) Merger requires approval of holders of simple majority of OILT common units; EPD has agreed to vote its then 54.8 million common units (66% of total OILT common units) in favor of the merger Total consideration of $6.0 billion Merger expected to be completed in first quarter of 2015 Combines EPD’s integrated system of midstream energy infrastructure and access to supplies of NGL, crude oil and refined products with OILT’s access to waterborne markets and storage Expected to be accretive to EPD’s distributable cash flow per unit in 2016

ACQUISITION OF OILTANKING (OILT) PRINCIPAL DRIVERS OF VALUE CREATION

At least $30 million of synergies and cost savings from the complete integration of OILT’s business into Enterprise’s system as well as public company cost savings Opportunities for new business and repurposing existing assets for “best use” to meet the growing demand for export and logistical services for petroleum products related to increase in North American crude oil and NGL production from the shale and non-conventional plays Secures ownership and control of OILT’s assets that are essential to EPD’s midstream

EPD is OILT’s largest customer, representing 31% of total 2013 revenues;

EPD accounted for 29% of OILT’s 2013 revenues

OILT provides essential dock and storage services to EPD LPG export and octane enhancement businesses, which accounted for 10% of EPD’s 2013 gross operating margin

Upon completion of EPD’s LPG export facility in 2016, EPD  assets with a value of

$1.5 billion would be located on land owned by OILT

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):

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):

DISTRIBUTABLE CASH FLOW

Distributable cash flow is 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. 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):
