Supplemental Non-GAAP Financial Measures

(Unaudited)

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as securities analysts, investors and lenders. We define Adjusted EBITDA as net income (loss) before interest expense, depreciation expense, amortization expense, non-cash stock compensation expense, amortization of deferred financing costs and other non-recurring items. Adjusted EBITDA is not a measure of net income as determined by GAAP.

Distributable cash flow is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as securities analysts, investors and lenders. We define distributable cash flow as Adjusted EBITDA less cash interest expense, and estimated maintenance capital expenditures. Distributable cash flow does not reflect changes in working capital balances and is not a presentation made in accordance with GAAP.

Adjusted EBITDA and distributable cash flow are non-GAAP supplemental financial measures that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess the financial performance of our assets, without regard to financing methods, capital structure or historical cost basis; our operating performance and return on capital as compared to other companies in the midstream energy sector, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing or capital structure; our ability to incur and service debt and fund capital expenditures; the ability of our assets to generate sufficient cash flow to make distributions to our unitholders; and the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

8

We believe that the presentation of Adjusted EBITDA and distributable cash flow will provide useful information to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to Adjusted EBITDA and distributable cash flow are net income and net cash provided by (used in) operating activities. Our non-GAAP financial measures of Adjusted EBITDA and distributable cash flow should not be considered as an alternative to GAAP net income or net cash provided by operating activities. Each of Adjusted EBITDA and distributable cash flow has important limitations as an analytical tool because it excludes some but not all items that affect net income and net cash provided by operating activities. You should not consider either Adjusted EBITDA or distributable cash flow in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA and distributable cash flow may be defined differently by other companies in our industry, our definitions of Adjusted EBITDA and distributable cash flow may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.
