ITEM 81.01. ~~Other~~ENTRY ~~Events~~INTO A MATERIAL DEFINITIVE AGREEMENT.

P. (the “~~Company~~Partnership”), ~~will~~ ~~give~~pursuant ~~presentations~~ to ~~investors~~which inthe ~~Orlando,~~Company ~~Florida~~agreed ~~and~~to ~~New~~deliver ~~York,~~all ~~New~~gas ~~York,~~gathered ~~respectively,~~by ~~which~~Columbia ~~will include~~Gas ~~information~~and ~~regarding~~delivered to the ~~proposed transaction~~Company ~~that~~upstream ~~resulted~~of ~~from~~ the Partnership’s ~~signing~~facilities offor anprocessing ~~Agreement~~at the Kenova, Boldman and ~~Plan~~Cobb ofplants ~~Redemption~~in ~~and~~exchange ~~Merger~~for ona ~~September~~monthly 5,processing ~~2007,~~fee bybased ~~and~~on ~~among~~the ~~MarkWest~~thermal ~~Energy Partners~~content ~~L.P.,~~of ~~MarkWest~~the natural ~~Hydrocarbon, Inc.~~gas ~~and~~delivered ~~MWEP,~~to Lthe Partnership.~~L.C~~

~~The~~On ~~information~~November 24, 2003, ~~included~~the ~~with~~Partnership and Company entered into an amendment to the Gas ~~this~~Processing ~~Current~~Agreement ~~Report~~providing asthat ~~Exhibit~~the ~~99.3~~Partnership ~~includes~~disposes ~~graphic~~of ~~images~~certain orliquids from ~~slides~~the ~~used~~Cobb inplant rather than redelivering them to a fractionation plant of the ~~presentation~~Company.

~~This~~On 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, non-cash compensation expense, and non-cash unrealized derivative gain / loss.December ~~Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP~~26, ~~and should not be considered in isolation or as a substitute for net~~ ~~income~~2007, 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 ~~financial~~Partnership ~~performance~~ and ~~operating~~Company ~~results~~entered ofinto ~~our fundamental business activities. Management believes that~~ the ~~presentation~~Second ofAmendment ~~Adjusted EBITDA is useful~~ to ~~lenders and investors because of its use in~~ the ~~midstream~~Gas ~~natural~~Processing ~~gas~~Agreement ~~industry and for master limited partnerships as an indicator of~~ (the ~~strength~~ ~~and~~“Amended ~~performance~~Gas ofProcessing ~~our ongoing business operations~~Agreement”). This ~~Additionally, management~~Amended ~~believes~~Gas ~~that~~Processing ~~Adjusted EBITDA provides additional and useful~~Agreement ~~information~~increases tothe ~~our~~processing ~~investors~~fee ~~for trending, analyzing, and benchmarking our operating results from period to period as compared to other companies~~ that ~~may have~~the ~~different~~Company ~~financing~~pays ~~and capital structures. The presentation of Adjusted EBITDA allows investors to view our performance in a manner similar to~~ the ~~methods~~ ~~used~~Partnership by ~~management and provides additional insight to our operating results~~$0. In08 ~~general, we define Distributable Cash Flow as net income or~~per ~~loss~~inlet ~~plus (i) depreciation~~Mcf, ~~amortization,~~effective ~~and~~upon 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~~substantial ~~of assets;~~completion ~~and (vii) the subtraction~~ of ~~sustaining capital expenditures. Distributable Cash Flow is a significant liquidity metric used by our senior management to compare basic cash flows generated by us to~~ the ~~cash distributions~~Kenova ~~we expect to pay partners. Distributable cash flow is also an~~plant ~~important~~upgrade ~~Non-GAAP~~in ~~financial~~consideration ~~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 ~~investment community~~additional ~~with~~frac ~~respect~~spread toincome ~~publicly~~that ~~traded~~will ~~partnerships such as ours because the~~be ~~value~~derived ~~of a partnership unit is in part measured~~ by ~~its yield (which in turn is based on~~ the ~~amount~~Partnership ~~of cash distributions a partnership pays to a unit holder). The GAAP measure most directly comparable to Distributable Cash Flow~~ and ~~Adjusted~~ ~~EBITDA~~marketed isby ~~net income. Please see~~ the ~~Appendix for our calculations of Adjusted EBITDA and Distributable Cash Flow along with the appropriate reconciliations~~Company.
