Item 1.01 Entry into a Material Definitive Agreement.

        The information included in Item 2.03 of this Current Report on Form 8-K is incorporated by reference into this Item 1.01 of this Current Report on Form 8-K.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

        On June 30, 2006, MarkWest Energy Partners L.P. (the “Partnership”) entered into a Purchase Agreement, dated June 30, 2006 (the “Purchase Agreement”), among the Partnership, its wholly-owned subsidiary, MarkWest Energy Finance Corporation (“Finance Corp” and together with the Partnership, the “Issuers”), certain subsidiary guarantors named therein (the “Guarantors”) and RBC Capital Markets Corporation, J.P. Morgan Securities Inc., and Wachovia Capital Markets, LLC, as representatives of the several initial purchasers, relating to the sale and issuance of $200,000,000 in aggregate principal amount of the Issuers’ 8 ½ % senior unsecured notes due 2016 (the “Senior Notes”). Affiliates of several of the initial purchasers, including RBC Capital Markets Corporation, J.P. Morgan Securities Inc., and Wachovia Capital Markets, LLC, are lenders under the Partnership’s credit facility.

        On July 6, 2006, the Issuers entered into (i) an Indenture, dated as of July 6, 2006 (the “Indenture”), among the Issuers, the Guarantors and Wells Fargo Bank, National Association, as trustee (the “Trustee”) and (ii) a Registration Rights Agreement, dated July 6, 2006, among the Issuers, the Guarantors and RBC Capital Markets Corporation, J.P. Morgan Securities Inc., and Wachovia Capital Markets, LLC, as representatives of the several initial purchasers, each relating to the Senior Notes.

        On July 6, 2006, the Senior Notes were issued pursuant to the Indenture in a transaction exempt from the registration requirements under the Securities Act of 1933, as amended (the “Securities Act”). The Senior Notes were sold within the United States only to qualified institutional buyers in reliance on Rule 144A under the Securities Act, and outside the United States only to non-U.S. persons in reliance on Regulation S under the Securities Act.

        The Senior Notes will mature on July 15, 2016, and interest is payable on the Senior Notes on each July 15 and January 15, commencing January 15, 2007.

        At any time prior to July 15, 2009, the Issuers may redeem up to 35% of the aggregate principal amount of notes issued under the Indenture at a redemption price of 108.5%, plus accrued and unpaid interest of the principal amount, with the proceeds of certain equity offerings. Before July 15, 2011, the Issuers may redeem some or all of the notes at a make-whole redemption price equal to 100% of the principal amount of the notes to be redeemed, plus any accrued and unpaid interest, plus a make-whole premium. On and after July 15, 2011, the Issuers may redeem some or all of the notes at redemption prices (expressed as percentages of principal amount) equal to 104.250% for the twelve-month period beginning on July 15, 2011, 102.833% for the twelve-month period beginning July 15, 2012, 101.417%, for the twelve-month period beginning on July 15, 2013 and 100.00% beginning on July 15, 2014, plus accrued and unpaid interest.

        The Indenture restricts the Partnership’s ability and the ability of certain of its subsidiaries to: (i) borrow money; (ii) pay distributions or dividends on equity or purchase, redeem or otherwise acquire equity; (iii) make investments; (iv) use assets as collateral in other transactions; (v) enter into sale and leaseback transactions; (vi) sell certain assets or merge with or into other companies; (vii) enter into transactions with affiliates; and (viii) engage in unrelated businesses. These covenants are subject to a number of important exceptions and qualifications. If at any time when the Senior Notes are rated investment grade by both Moody’s Investors Service, Inc. and Standard & Poor’s Rating Services and no Default (as defined in the Indenture) has occurred and is continuing, many of such covenants will terminate and the Partnership and its subsidiaries will cease be subject to such covenants.

        The Indenture provides that each of the following is an Event of Default: (i) default for 30 days in the payment when due of interest on the Senior Notes; (ii) default in payment when due of the principal of, or premium, if any, on the Senior Notes; (iii) failure by the Partnership to comply with certain covenants relating to merger, consolidation or sale of assets; (iv) failure by the Partnership to comply for 30 days after notice with provisions of the indenture relating to change of control or asset sales or certain covenants described in the Indenture (provided that notice need

not be given and an Event of Default shall occur, 30 days after any breach of the covenants relating to restricted payments or incurrence of indebtedness and issuance of disqualified equity) in each case other than a failure to purchase Senior Notes which will constitute an Event of Default under (ii) above and other than a failure to comply with certain covenants relating to merger, consolidation or sale of assets which will constitute an Event of Default under (iii) above; (v) failure by the Partnership to comply for 60 days after notice with any of the other agreements in the Indenture; (vi) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by either Issuer or any of the Partnership’s restricted subsidiaries (or the payment of which is guaranteed by the Partnership or any of its restricted subsidiaries), if that default: (a) is caused by a failure to pay principal of, or interest or premium, if any, on such indebtedness prior to the expiration of the grace period provided in such indebtedness on the date of such default (a “Payment Default”); or (b) results in the acceleration of such indebtedness prior to its stated maturity, and, in each case, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more; (vii) failure by either Issuer or any of the Partnership’s restricted subsidiaries to pay final judgments aggregating in excess of $10.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (viii) except as permitted by the Indenture, any subsidiary guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its guarantee of the Senior Notes; and (ix) certain events of bankruptcy or insolvency described in the Indenture with respect to the Issuers or any of the Partnership’s significant subsidiaries or any group of restricted subsidiaries that, taken as a whole, would constitute a significant subsidiary. In the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to either Issuer, all outstanding Senior Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the then outstanding Senior Notes may declare all the notes to be due and payable immediately.

        Pursuant to the Registration Rights Agreement, the Issuers and the Guarantors will use their reasonable best efforts to file an exchange offer registration statement with the SEC with respect to an offer to exchange the Senior Notes for substantially identical notes that are registered under the Securities Act. Additionally, the Issuers and the Guarantors have agreed to promptly commence the exchange offer after the exchange offer registration statement is declared effective by the SEC and to use their reasonable best efforts to complete the exchange offer not later than 60 days after such effective date. Under some circumstances, in lieu of a registered exchange offer, the Issuers and the Guarantors have agreed to file a shelf registration statement with respect to the notes and to use their reasonable best efforts to keep the shelf registration statement effective until the earlier of the period specified in Rule 144(k) or the sale pursuant to the shelf registration statement of all of the Senior Notes registered thereunder. The Issuers and the Guarantors are required to pay additional interest if they fail to comply with their obligations to register the Senior Notes within the specified time periods.

        The description set forth above is qualified in its entirety by the Purchase Agreement, Indenture, the form of Senior Notes and the Registration Rights Agreement, which are filed herewith as exhibits.

        On July 6, 2006, we closed both our private placement of $200 million aggregate principal amount of Senior Notes due 2016 and our public offering of 3,000,000 common units.
