INDECK CAPITAL, INC. AND SUBSIDIARIES REPORT ON AUDIT OF CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEAR ENDED DECEMBER 31, 1999 11

REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors of Indeck Capital, Inc. and Subsidiaries In our opinion, based upon our audit and the report of other auditors, the accompanying consolidated balance sheet and the related consolidated statements of operations, changes in stockholders' equity and cash flows present fairly, in all material respects, the financial position of Indeck Capital, Inc. and Subsidiaries (the "Company") at December 31, 1999, and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States. These consolidated financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these consolidated financial statements based on our audit. We did not audit the financial statements of EIF Investors, Inc., a wholly-owned subsidiary, which statements reflect total assets of approximately $5,884,000 at December 31, 1999, and total revenues of approximately $2,900,000 for the year ended December 31, 1999. Those statements were audited by other auditors whose report thereon has been furnished to us, and our opinion expressed herein, insofar as it relates to the amounts included for EIF Investors, Inc., is based solely on the report of other auditors. We conducted our audit of the consolidated financial statements in accordance with auditing standards generally accepted in the United States which require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated financial statement presentation. We believe that our audit provides a reasonable basis for the opinion expressed above.

INDECK CAPITAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- 1. ORGANIZATION OF INDECK CAPITAL, INC.: Indeck Capital, Inc. (the "Company") was incorporated in 1994 to participate in the rapidly changing power generation industry. The Company is engaged in the acquisition, development, ownership and operation of power generation facilities through direct investment and investment in various projects and funds. The Company has primarily focused on the North American market. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include the accounts of Indeck Capital, Inc. and its majority-owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. Investments in partially-owned affiliates are accounted for by the equity method when the Company's interest exceeds 20%. ESTIMATES: Preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingencies at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. CASH EQUIVALENTS: The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. PROPERTY AND EQUIPMENT: Property and equipment are stated at cost. Depreciation is provided using the straight line method over the lives of the related assets, ranging from 3-30 years. INVESTMENTS: As they represent interests in limited partnerships, the Company's investments are recorded under the equity method. The Company's investments are increased by its share of earnings and reduced by distributions received from or losses incurred by the investment. GOODWILL: Goodwill is amortized on the straight-line method over 37 years. The Company continually assesses the carrying value of goodwill for potential impairment using an undiscounted cash flow approach. POWER SALES RECEIPTS IN EXCESS OF AVOIDED COSTS: The Company's wholly-owned subsidiary, Adirondack Hydro Development Corporation ("AHDC"), entered into a 40-year power purchase agreement ("PPA") with Niagara Mohawk Power Company ("NMPC") between 1985 and 1992, committing the parties to sell and buy, respectively, the output of the Otter Creek facility. The Warrensburg Hydro Power facility, which is owned through subsidiaries of AHDC, also has a 40-year PPA with NMPC. The contracts establish a base rate per kilowatt hour of energy and an annual fixed escalator for the first 15-year period. The cumulative difference between the base payment and "avoided cost" (the greater of $0.06 per kwh or NMPC's actual cost of production avoided by reason of its agreement with AHDC for the Otter Creek facility, and NMPC's actual cost of production avoided by reason of its agreement for the Warrensburg Hydro Power facility), including interest at 125 percent of the 360-day Treasury bill rate, is tracked by NMPC and will be used to adjust the contractual rate over the second 15 years of the respective agreements. In addition, if the projected cumulative difference exceeds the cost of the facilities at any time 27

during years 6 through 15, the fixed escalation is suspended and the respective rates may be reduced. Revenue is recognized when the power is transmitted in accordance with the terms of the PPA and is included in project fees in the consolidated statement of operations. At December 31, 1999, the cumulative excess of the base payment over the avoided cost (power sales receipts in excess of avoided costs), plus interest, was $6,133,856. INCOME TAXES: Deferred income taxes are provided on a liability method whereby deferred income tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred income tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred income tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Deferred income tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. 3. ACQUISITIONS: INDECK COLORADO, L.L.C.: On November 23, 1999, the Company entered into an agreement with the Public Service Company of Colorado ("PSCC") to purchase PSCC's ownership interests in two power plants, the Arapahoe plant and the Valmont plant, and to operate these plants for PSCC. To execute this transaction, the Company formed Indeck Colorado, L.L.C. ("Indeck Colorado") with Black Hills Corporation ("Black Hills"). The Company and Black Hills are each 50% members in Indeck Colorado, although the Company is the managing member of the venture and has the exclusive authority to manage the operations and affairs of Indeck Colorado. Indeck Colorado obtained an $82,000,000 financing arrangement from Black Hills and borrowed $52,319,000 under this arrangement on December 22, 1999 to purchase the plant ownership interests from PSCC (Note 7). The acquisition was accounted for using the purchase method of accounting, with the entire purchase price allocated to the plant assets purchased, which consisted of construction in progress at December 31, 1999. NORTH AMERICAN FUNDING, L.L.C.: On December 10, 1999, the Company issued 40,000 shares of common stock to the members of North American Funding, L.L.C. ("NAF"), a related entity, in exchange for each member's ownership interest in NAF. The assets and liabilities of NAF were transferred to the Company at historical cost as NAF and the Company are under common ownership control. NAF's total assets and liabilities were approximately $7,100,000 and $6,200,000, respectively, at December 10, 1999, including $246,000 of cash acquired. The following unaudited information presents, on a pro forma basis, the results of operations as if the acquisitions had occurred at the beginning of 1999: Revenues and income from equity investments $11,600,000 Net loss (1,500,000) 28

INDECK NORTH AMERICAN POWER FUND, L.P. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - ------------------------------------------------------------------------------- 1. ORGANIZATION AND OPERATIONS Indeck North American Power Fund, L.P. (the "Partnership") is a limited partnership whose operations commenced May 16, 1995. The Partnership terminates in 2005. The purpose and business of the Partnership is to invest in established utility and non-utility generating assets in the United States and Canada. Indeck North American Power Partners, L.P. (the "General Partner") serves as the general partner and has the exclusive authority for the management, operation and policy of the Partnership. The General Partner has a 1% interest in the Partnership. Profits and losses are generally allocated in a manner such that the capital accounts of partners, immediately after making such allocation, are proportionate to the distributions that would have been made pursuant to the agreement if the partnership were dissolved. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of Indeck North American Power Fund, L.P. and its subsidiaries, Indeck Harbor, L.L.C. ("Indeck Harbor") and Indeck Pepperell Power Associates, Inc. ("Indeck Pepperell"), both of which are 99% owned. All significant intercompany transactions have been eliminated. ESTIMATES The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. CASH EQUIVALENTS The Partnership considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. INCOME TAXES The profits and losses of the Partnership are subject to income taxes directly at the partner level. Accordingly, the Partnership's financial statements do not reflect a provision for income taxes at the Partnership level. Deferred income taxes at Indeck Pepperell are provided on a liability method whereby deferred income tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards, and deferred income tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred income tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Deferred income tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. 46

PLANT AND EQUIPMENT Plant and equipment are stated at cost. Depreciation is provided for using the straight-line method over the estimated lives of the related assets, ranging from 5-25 years. The majority of these assets relate to the generation facility. Depreciation expense was $556,000 for 1999. REVENUE RECOGNITION Operating revenue is recognized when steam is transmitted. 3. EQUITY INVESTMENT IN HARBOR COGENERATION COMPANY Under the terms of the general partnership agreement, Indeck Harbor, L.L.C. cannot exercise effective control over the investment in Harbor Cogeneration Company (the "Venture"). Accordingly, Indeck Harbor records its investment in the Venture under the equity method, whereby the investment is increased by its share of the Venture's earnings and reduced by distributions received from the Venture. The Venture entered into a power sales agreement (the "Agreement") with Southern California Edison ("Edison") for the sale of energy produced by the cogeneration facility operated by the Venture. The Agreement has a term of 30 years from April 12, 1989. The Venture is paid energy prices based on 20% of the stated marginal cost of energy and 80% of avoided cost for a period of 10 years, both as defined in the Agreement. For the remaining term of the Agreement, energy prices will equal 100% of avoided cost. In addition to the above energy prices, the Venture is paid capacity revenues over the term of the Agreement based on a stated amount per kilowatt hour as adjusted by a performance bonus factor. Effective February 15, 1999, the Venture entered into a Contract Termination Agreement with Edison which terminated the Agreement. Upon termination, the Venture may continue to sell power, which it did during certain months in 1999, but operations are presently suspended while management explores available options for the Venture, which may include entering into new power sales arrangements that would terminate the Contract Termination Agreement. The Contract Termination Agreement requires Edison to pay the Venture $126.5 million, in quarterly payments ranging from $4.6 million to $2.1 million from the effective date through October 1, 2008 for early termination of the Agreement. During 1999, the Venture recorded approximately $16.4 million related to the Contract Termination Agreement, which is included in operating revenues in the Venture's Statement of Income. 47

OTHER INCOME In 1999, other income is primarily comprised of a settlement payment received related to a breach of contract dispute. 48

5. RELATED PARTY TRANSACTIONS In accordance with the Limited Partnership Agreement, the General Partner receives an annual management fee equal to 1.5% of the Limited Partners' aggregate capital commitments as defined. In 1999, the Partnership paid a management fee of $2,153,000, as well as reimbursement of certain expenditures of $376,000. On December 10, 1999, Indeck Capital, Inc. ("Indeck"), a limited partner, acquired North American Funding, L.L.C. ("NAF"), also a limited partner. As a result of this transaction, Indeck assumed NAF's partnership interest in the Partnership. 6. INCOME TAXES The components of the deferred tax assets and liabilities at Indeck Pepperell are as follows at December 31, 1999: Deferred tax asset: Net operating loss carryforward $ 2,274,000 Deferred tax liability: Plant and equipment 304,000 ----------------- 1,970,000 Valuation allowance 1,970,000 ----------------- Net deferred income taxes $ - ================= Indeck Pepperell has net operating loss carryforwards of approximately $5,647,000 expiring in 2011-2014, available to offset future taxable income.

SUBSEQUENT EVENT On January 28, 2000, Dynegy Marketing and Trade Capital Corp. ("DMTCC") was acquired by Black Hills Energy Capital, Inc. ("Black Hills"). As a result of this transaction, Black Hills assumed DMTCC's partnership interest in the Partnership. 49

NORTHERN ELECTRIC POWER CO., L.P. NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: a. ORGANIZATION: Northern Electric Power Co., L.P. ( the "Partnership") was formed as a limited partnership under the laws of the State of New York on March 11, 1992; it organized and began business on March 1, 1994 for the purpose of developing, rehabilitating, and operating a hydroelectric facility located on the Hudson River, Town of Moreau, Saratoga County, New York. The facility began generating power on November 22, 1995. The financial statements include only the assets and liabilities which relate to the Partnership and do not include any items attributable to the partners' individual activity. b. USE OF ESTIMATES: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions (e.g., depreciable lives) that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. c. CASH AND CASH EQUIVALENTS: Cash includes all cash equivalents that are highly liquid investments with a maturity of three months or less when purchased. d. PROPERTY AND EQUIPMENT: Property and equipment are carried at cost. Cost includes expenditures for construction, capitalized interest, on-site and title insurance, and attorney's costs of acquisition. The hydroelectric facilities are being depreciated on a straight-line basis over 40 years. The Partnership evaluates the recoverability of the net carrying amount of the hydroelectric facilities on an ongoing basis by reference to the anticipated future undiscounted cash flows from the operations of the project. Depreciation expense was $2,475,918 for the year ended December 31, 1999. e. DEFERRED FINANCING COSTS: Deferred financing costs are amortized over the term of the related debt agreement (15 years). f. INCOME TAXES: No provision has been made for federal and state income taxes because these taxes are the responsibility of the partners. 2. LONG-TERM DEBT: Long-term debt consists of the following at December 31, 1999: Term loan, Toronto-Dominion Bank, floating interest (7.625% at December 31, 1999), quarterly principal and interest payments of varying amounts, final maturity December 31, 2010 $77,969,047 =========== 72

Collateral for the term loan and the operating line of credit discussed below includes a mortgage on all facilities, leases and rights, including the right to receive payments from Niagara Mohawk Power Corporation ("NMPC") pursuant to a Power Purchase Agreement ("PPA") with a 40-year term. The loan agreement contains various restrictive covenants including the maintenance of a minimum debt service coverage ratio. Minimum principal payments under the existing term loan agreement for the five years following December 31, 1999 and thereafter are as follows: 2000 $ 3,822,883 2001 4,667,474 2002 5,200,900 2003 5,689,873 2004 6,490,011 Thereafter 52,097,906 ----------- $77,969,047 =========== The Partnership also has a $5 million operating line of credit with the Toronto-Dominion Bank ("Bank") through April 2000, which automatically renews every three years through December 31, 2010. The Partnership had borrowings of $200,000 outstanding under this agreement at December 31, 1999. Borrowings under the agreement bear interest at LIBOR plus 1.875% (LIBOR was 6.44% at December 31, 1999). To provide some degree of protection against the potential impact of rising interest rates, effective March 29, 1996, the Partnership entered into an amortizing interest rate swap agreement that expires June 29, 2006. This agreement effectively changes the Partnership's interest rate exposure on approximately 75% of the future floating rate term loan to a fixed rate. Under the agreement, each quarter the Partnership pays a fixed rate of 8.835% on the notional amount to the Bank (notional amount was $58,785,814 at December 31, 1999), and receives a variable rate from the Bank (6.18125% at December 31, 1999). The net amount payable or receivable is recorded as interest expense. At December 31, 1999, the carrying amount of all debt obligations approximate their fair values, and the fair value of the interest rate swap agreement was $4,797,300, representing the cost the Partnership would incur to terminate the agreement. 3. RELATED PARTY TRANSACTIONS: Fees to Adirondack Hydro Development Corporation ("Adirondack"), a limited partner, during 1999 were $750,000, of which $324,144 is included in accrued expenses at December 31, 1999. Included in accounts payable at December 31, 1999 are amounts payable to affiliated companies of $37,377. 73

4. POWER PURCHASE AGREEMENT: The Partnership has entered into a 40-year power purchase agreement with NMPC, committing the parties to sell and buy, respectively, the output of the hydroelectric facility. The PPA establishes contract energy payment rates for each of the 40 years. The contract energy payment rate was $0.09002 per kilowatt hour at December 31, 1999. Revenue is recognized when the power is transmitted in accordance with the terms of the PPA. On August 1, 1996, NMPC submitted a proposal to nineteen Independent Power Producers ("IPPs") to restructure 44 of the IPPs' PPAs with NMPC concurrent with an internal restructuring of NMPC. Adirondack's projects, including the Partnership, made up seven of the 44 PPAs subject to NMPC's proposal. However, in June 1997, NMPC withdrew its proposal for all hydroelectric projects included in the original group of 44 PPAs. As of December 31, 1997, agreements had been reached with sixteen of the nineteen IPPs on the restructuring of 29 of the PPAs. As of March 20, 1998, the New York State Public Service Commission approved NMPC's restructuring plan. The plan included the restructuring of 29 PPAs which represent over 80% of NMPC's "out-of-market" PPAs. Adirondack initiated separate discussions with NMPC in November 1997 regarding the restructuring of its seven PPAs. Discussions are ongoing. A term sheet was signed for two of the seven PPAs (Warrensburg Hydro Power Limited Partnership and Sissonville Limited Partnership) in 1999. Adirondack management anticipates that a final settlement for the restructuring of the remaining PPAs will be reached in 2000. 5. LEASES The Partnership leases the land upon which its hydroelectric facilities are situated from NMPC and the adjacent riverbed from the State of New York. These lease agreements extend through the end of the PPA with NMPC. Total rental expense in 1999 was $60,349. 74
