NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 1: ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION West Shore Processing Company, L.L.C. ("West Shore" or the "Company") was established on May 6, 1996 as a venture dedicated to natural gas gathering, treatment, processing and NGL marketing in Manistee, Mason and Oceana Counties in Michigan. On May 6, 1996, Michigan Energy Company LLC ("MEC") conveyed 98% of its ownership interest in Basin Pipeline, L.L.C. ("Basin") to West Shore, and 1.2% to MarkWest Michigan LLC, the predecessor to MarkWest Michigan, Inc. ("MWM"), a wholly-owned subsidiary of MarkWest Hydrocarbon, Inc. The transfer of Basin from MEC to West Shore was accounted for as a transaction between entities under common control and, accordingly, the assets and liabilities of Basin continue to be reflected at MEC's predecessor basis. As of December 31, 1996, West Shore was 47% owned by MWM and 53% owned by MEC. MWM has the right to acquire up to a 60% ownership interest in West Shore based on its levels of future capital expenditures. PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of the Company and its 98% owned subsidiary, Basin. All significant intercompany accounts and transactions have been eliminated in consolidation. CONCENTRATION OF CREDIT RISK Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash. The Company maintains cash in bank deposit accounts that at times may exceed federally insured limits. To date, the Company has not incurred a loss relating to these concentrations of credit risk. The Company derives all of its revenue from three customers. FAIR VALUE OF FINANCIAL INSTRUMENTS The Company's financial instruments consist of cash and cash equivalents, trade receivables, accounts payable, other current liabilities and notes payable. Except for long-term notes receivable and long-term debt, the carrying amounts of these financial instruments approximate their fair value at December 31, 1996 due to their short maturities. At December 31, 1996, based on rates available for similar types of long-term notes receivable and long-term debt, respectively, the fair value of these items was not materially different from their carrying values. USE OF ESTIMATES The preparation of the Company's financial statements in conformity with generally accepted accounting principles requires the Company's management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements. Actual results could differ from those estimates. 6 WEST SHORE PROCESSING COMPANY, L.L.C. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS CASH AND CASH EQUIVALENTS The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. MATERIALS AND SUPPLIES INVENTORY Materials and supplies are valued at the lower of average cost or estimated net realizable value. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment consists of a natural gas pipeline and gas gathering and processing equipment which are recorded at cost. Renewals and betterments that substantially extend the useful life of the assets are capitalized. Maintenance and repairs are expensed when incurred. Depreciation is computed using the straight-line method over estimated useful lives ranging from seven to twenty years. Interest costs for the construction or development of significant long-term assets are capitalized and amortized over the related asset's estimated useful life. Gains and losses on retirements are included in results of operations. Construction-in-progress consists primarily of a pipeline extension, which is accounted for at cost. IMPAIRMENT OF LONG-LIVED ASSETS The Company follows Statement of Financial Accounting Standards ("SFAS") No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, which requires that an impairment loss be recognized when the carrying amount of an asset exceeds the expected future undiscounted net cash flows. In 1996, the Company recorded a charge of $136,984 for the write-off of intangible costs related to an abandoned well extension. REVENUE RECOGNITION Revenue for sales or services is recognized at the time the product is delivered or at the time the service is performed. INCOME TAXES As a Limited Liability Company, the tax consequences of the Company's operations are the responsibility of each member. Accordingly, the accompanying financial statements do not include a provision for income taxes. SUPPLEMENTAL CASH FLOW INFORMATION Interest of $13,431 was paid for the period from May 6, 1996 through December 31, 1996. Interest expense in 1996 is net of $19,010 capitalized in relation to various construction projects. MEC made a non-cash capital contribution of approximately $9.8 million, which consisted of the aggregate amount of debt and accrued interest forgiven. 7 WEST SHORE PROCESSING COMPANY, L.L.C. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS In connection with the Basin Pipeline acquisition in 1996, the Company assumed a $431,000 note used to finance certain assets previously purchased from the Dow Chemical Company. As of December 31, 1996, $336,791 was outstanding under this note. The note, which carries an imputed interest rate of 5%, requires that the Company make payments of approximately $13,000 a month, until maturity in early 1999. NOTE 2. LONG-TERM NOTES RECEIVABLE Notes receivable at December 31, 1996 consists of a note receivable (the "Note") from Michigan Production Company, LLC ("MPC"). The Note bears an interest rate of 5.98%, and is for all sums expended by the Company for the construction of the 31-mile extension to the Basin Pipeline. Upon completion of the pipeline extension, MPC expects to contribute the fixed assets to the Company as full payment for the note balance and accrued interest. NOTE 3. COMMITMENTS AND CONTINGENCIES The Company leases certain operating equipment under non-cancelable agreements accounted for as operating leases. The following is a schedule by years of future minimum lease payments under such operating leases: At December 31, 1996 --------------- 1997 $ 192,000 1998 192,000 1999 43,899 --------------- Total minimum lease payments $ 427,899 =============== Total rent expense under operating leases was $91,753 for the period from May 6, 1996 through December 31, 1996. The Company maintains a capital lease for a two-stage compressor with an asset balance of $124,333, net of accumulated amortization of $16,421. The following is a schedule by years of future minimum lease payments under capital leases together with the present value of the minimum lease payments: At December 31, 1996 --------------- 1997 $ 33,000 1998 33,000 1999 33,000 2000 2,750 ---------------- Total minimum lease payments 101,750 Less: amount representing interest (11,842) ----------------- Present value of minimum lease payments $ 89,908 ================= 8 WEST SHORE PROCESSING COMPANY, L.L.C. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company is involved in various litigation and administrative proceedings arising in the normal course of business. In the opinion of management, any liabilities that may result from these claims will not, individually or in the aggregate, have a material adverse effect on the Company's financial position or results of operations. NOTE 4. RELATED PARTY TRANSACTIONS During 1996, the Company received financial support from MWM and MarkWest Hydrocarbon, Inc. ("Hydrocarbon"), the 100% owner of MWM, so as to permit the Company to continue its operations during this period. MWM and Hydrocarbon have indicated that they will continue to provide financial support to the Company through December 31, 1997. MWM, Hydrocarbon, and MEC pay for various operating expenses on West Shore's behalf, for which they are reimbursed their actual cost. As a result of such transactions, at December 31, 1996, the Company had payables outstanding to MWM and MEC in the amounts of $279,270 and $330,194, respectively. A portion of Hydrocarbon's debt was utilized to provide West Shore with financing for construction-in-progress. Accordingly, Hydrocarbon, through MWM, allocated $19,010 of its interest expense for the period from May 6, 1996 through December 31, 1996 to West Shore. Such interest was capitalized. For the period from May 6, 1996 through December 31, 1996, West Shore and its subsidiary provided processing and transportation and compression services for MPC, an affiliate of the Company, in the amount of $436,613 and $206,829, respectively. In addition, the Company is constructing various well extensions on behalf of MPC for which the Company will be reimbursed its actual cost. At December 31, 1996, the Company had $118,530 in receivables from MPC as a result of such transactions. 9 (b) Pro Forma Financial Information. MARKWEST HYDROCARBON, INC.

MARKWEST HYDROCARBON, INC. NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS (a) Prior to the acquisition, MarkWest Hydrocarbon, Inc. ("MarkWest") owned 60% of West Shore Processing Company, L.L.C. ("West Shore") through its 100% owned subsidiary, MarkWest Michigan, Inc. Accordingly, the historical financial statements of MarkWest include the accounts of West Shore on a fully consolidated basis. (b) Represents the collection of approximately $734,000 due to MarkWest Michigan, Inc. from Michigan Energy Company, L.L.C. ("MEC"), the original 40% owner, at the time of the acquisition. (c) Represents the transfer of a receivable to construction in progress. The receivable, which was due from MEC, was related to a construction project the Company was building on behalf of MEC. As part of the acquisition, the Company agreed to fund MEC's 40% share of the construction project. (d) Represents the excess of the fair value of net assets acquired over cost allocated to reduce the values otherwise assignable to noncurrent assets. (e) Represents debt incurred to fund the acquisition, less accounts receivable collected on closing. (f) Represents the elimination of the 40% minority interest ownership in West Shore. (g) Represents the decrease in depreciation expense and accumulated depreciation, that would have occurred as a result of (d) above, assuming an estimated useful life of 20 years. (h) Represents interest expense of $499,000 and $665,000 for the nine months ending September 30, 1997 and the year ending December 31, 1996, respectively, at 8.5% on the amount assumed to be borrowed in conjunction with the acquisition, net of capitalized interest. Interest capitalized for the same periods was $70,000 and $93,000, respectively.
