OnThis ~~November 24~~presentation utilizes the Non-GAAP financial measures of Adjusted EBITDA and Distributable Cash Flow. We define Adjusted EBITDA as net income or loss before interest, provision for income taxes, depreciation and amortization expense, ~~2003~~non-cash compensation expense, ~~the~~and ~~Partnership~~non-cash unrealized derivative gain / loss. Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP, and ~~Company~~should ~~entered~~not ~~into~~be anconsidered ~~amendment~~in isolation or as a substitute for net income, income from operations, or cash flow as reflected in our financial statements. Adjusted EBITDA is presented because such information is relevant and is used by management, industry analysts, investors, lenders, and rating agencies to assess the ~~Gas~~financial performance and operating results ~~Processing~~of ~~Agreement~~our ~~providing~~fundamental business activities. Management believes that the presentation ~~Partnership~~of ~~disposes~~Adjusted EBITDA is useful to lenders and investors because of its ~~certain~~use ~~liquids~~in the midstream natural gas industry and for master limited partnerships as an indicator of the strength and performance of our ongoing business operations. Additionally, management believes that Adjusted EBITDA provides additional and useful information to our investors for trending, analyzing, and benchmarking our operating results from period to period as compared to other companies that may have different financing and capital structures. The presentation of Adjusted EBITDA allows investors to view our performance in a manner similar to the ~~Cobb~~methods ~~plant~~used ~~rather~~by ~~than~~management ~~redelivering~~and ~~them~~provides additional insight to our operating results. In general, we define Distributable Cash Flow as net income or loss plus (i) depreciation, amortization, and accretion expense; (ii) non-cash earnings from unconsolidated affiliates; (iii) contributions to unconsolidated affiliates net of expansion capital expenditures; (iv) non-cash compensation expense; (v) non-cash derivative activity; (vi) gains and losses on the sale of assets; and (vii) the subtraction of sustaining capital expenditures. Distributable Cash Flow is a ~~fractionation~~significant ~~plant~~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 ~~Company~~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 and Adjusted EBITDA is net income. Please see the Appendix for our calculations of Adjusted EBITDA and Distributable Cash Flow along with the appropriate reconciliations.

OnCautionary December 26, 2007, the Partnership and Company entered into the Second Amendment to the Gas Processing Agreement (the “Amended Gas Processing Agreement”). This Amended Gas Processing Agreement increases the processing fee that the Company pays the Partnership by $0.08 per inlet Mcf, effective upon the substantial completion of the Kenova plant upgrade in consideration for the additional frac spread income that will be derived by the Partnership and marketed by the Company.Statements
