We have audited the accompanying statements of revenues and direct operating expenses of CMS Oil & Gas Company's Michigan properties, as described in Note 1, for the three years ended December 31, 1999, 1998 and 1997. These financial statements are the responsibility of management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. The accompanying statements of revenues and direct operating expenses reflect the revenues and direct operating expenses attributable to CMS Oil & Gas Company's Michigan properties, as described in Note 2, and are not intended to be a complete presentation of the revenues and expenses of CMS Oil & Gas Company's Michigan properties. In our opinion, the financial statements referred to above present fairly, in all material respects, the revenues and direct operating expenses of CMS Oil & Gas Company's Michigan properties, as described in Note 1, for the three years ended December 31, 1999, 1998 and 1997, in conformity with accounting principles generally accepted in the United States of America. Fort Worth, Texas April 7, 2000 3 CMS OIL & GAS COMPANY'S MICHIGAN PROPERTIES STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997 (Dollars in Thousands) - ------------------------------------------------------------------------------ 1999 1998 1997 REVENUES - Oil, gas and related product sales $36,363 $37,624 $48,050 DIRECT OPERATING EXPENSES - Lease operating expenses 13,701 13,673 14,081 ------- ------- ------- EXCESS OF REVENUES OVER DIRECT OPERATING EXPENSES $22,662 $23,951 $33,969 ======= ======= ======= See notes to statements of revenues and direct operating expenses. 4 CMS OIL & GAS COMPANY'S MICHIGAN PROPERTIES NOTES TO STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997 - ----------------------------------------------------------------------------- 1. THE PROPERTIES The accompanying statements represent the revenues and direct operating expenses attributable to the net interest in CMS Oil & Gas Company's Michigan properties (the "Michigan Properties") in producing wells and certain non-producing leases sold to Quicksilver Resources Inc. ("Quicksilver"). The total purchase price, including related affiliated companies, was approximately $164 million, as adjusted, and the properties are located in the state of Michigan. The acquisition was effective as of January 1, 2000, and closed on March 31, 2000. These acquired properties and their related operations are included in Quicksilver's consolidated financial statements from the date of closing. 2. BASIS OF PRESENTATION The historical financial statements reflecting financial position, results of operations and cash flows required by accounting principles generally accepted in the United States of America are not presented, since such information is neither readily available on an individual property basis nor meaningful for the properties acquired because the entire acquisition cost is being assigned to oil and gas properties. Accordingly, the statements of revenues and direct operating expenses are presented in lieu of the financial statements required under Rule 3-05 of Securities and Exchange Commission ("SEC") Regulation S-X. The accompanying statements of revenues and direct operating expenses represent CMS Oil & Gas Company's net ownership interest in the properties acquired by Quicksilver and are presented on the successful efforts basis of accounting. Depreciation, depletion and amortization; allocated general and administrative expenses; interest expense and income; and income taxes have been excluded because the property interest acquired represents only a portion of a business, and the expenses incurred are not necessarily indicative of the expenses to be incurred by Quicksilver. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of certain revenues for the reported period. Estimates and assumptions are also required in the disclosure of contingent assets and liabilities as of the date of the financial statements. Actual results may differ from such estimates. 3. CONTINGENT LIABILITIES Given the nature of the properties acquired and as stipulated in the purchase agreement, Quicksilver is subject to loss contingencies, if any, pursuant to existing or expected environmental laws, regulations and leases covering the acquired properties. 4. OIL AND NATURAL GAS RESERVES INFORMATION (UNAUDITED) Unaudited reserve information related to the properties acquired is presented in the table below. Proved oil and gas reserves have been estimated by Quicksilver's independent petroleum 5 engineers as of January 1, 2000, and by CMS Oil & Gas Company's independent petroleum engineers at January 1, 1999, 1998 and 1997, in accordance with guidelines established by the SEC. Accordingly, the following reserve estimates are based upon economic and operating conditions existing as of each date. There are numerous uncertainties inherent in establishing quantities of proved reserves. The following reserve data represent estimates only and should not be construed as being exact. In addition, the present values should not be construed as the current market value of the Michigan Properties or the cost that would be incurred to obtain equivalent reserves. Estimated Reserves - Reserve quantities were estimated by Quicksilver's independent petroleum engineers as of January 1, 2000, and by CMS Oil & Gas Company's independent petroleum engineers at January 1, 1999, 1998 and 1997. Changes in the estimated net quantities of crude oil and natural gas reserves, all of which are located in the continental United States, are as follows: Gas Oil (Mmcf) (Mbbl) Proved reserves: As of January 1, 1997 137,431 930 Revision of estimates (7,988) 320 Production for 1997 (15,980) (311) ------- ---- As of January 1, 1998 113,463 939 Revision of estimates 5,238 279 Production for 1998 (14,140) (347) ------- ---- As of January 1, 1999 104,561 871 Revision of estimates 52,697 (350) Production for 1999 (12,152) (286) ------- ---- As of January 1, 2000 145,106 235 ======= ==== Proved developed reserves: As of January 1, 1997 137,431 930 As of January 1, 1998 111,143 939 As of January 1, 1999 100,791 871 As of January 1, 2000 109,160 235 Standardized Measure - The following tables present the Michigan Properties' standardized measure of discounted future net cash flows and changes therein relating to proved oil and gas reserves and were computed using reserve valuations based on regulations prescribed by the SEC. These regulations provide that the oil, condensate and gas price structure utilized to project future net cash flows reflects current prices at each date presented and has been escalated only when known and determinable price changes are provided by contract. Future production, development and net abandonment costs are based on current costs without escalation. The resulting net future cash flows have been discounted to their present values based on a 10% annual discount factor the years ended December 31, 1999, 1998 and 1997, in thousands, as follows: 6 1999 1998 1997 Future cash flows $ 341,639 $ 267,347 $ 354,560 Future production and development costs (161,261) (115,156) (148,289) Future income tax expense (61,329) (51,745) (70,132) --------- --------- --------- Future net cash flows 119,049 100,446 136,139 10% annual discount for estimated timing of cash flows (59,133) (33,273) (44,658) --------- --------- --------- Standardized measure of discounted future net cash flows $ 59,916 $ 67,173 $ 91,481 ========= ========= ========= Changes in the standardized measure of discounted future net cash flows are as follows: 1999 1998 1997 Net changes in price and production costs $(21,988) $(27,750) $(38,863) Revision of estimates 33,623 7,943 (8,427) Changes in estimated future development costs 11,767 2,283 1,079 Net change in income taxes 3,738 12,522 23,328 Sales of oil and gas, net of production costs (22,662) (23,951) (33,969) Accretion of discount 6,717 9,148 13,677 Other (18,452) (4,503) (2,109) -------- -------- -------- Net decrease $ (7,257) $(24,308) $(45,284) ======== ======== ======== Estimated future cash inflows are computed by applying year-end prices of oil and gas to year-end quantities of proved reserves. Estimated future development and production costs are determined by estimating the expenditures to be incurred in developing and producing the proved oil and gas reserves in future years, based on year-end costs and assuming continuation of existing economic conditions. These estimates are furnished and calculated in accordance with requirements of the Financial Accounting Standards Board and the SEC. Because of unpredictable variances in expenses and capital forecasts, crude oil and natural gas price changes, and the fact that the bases for such estimates vary significantly, management believes the usefulness of these projections is limited. Estimates of future net cash flows do not necessarily represent management's assessment of future profitability or future cash flows for the Michigan Properties. * * * * * * 7 INDEPENDENT AUDITORS' REPORT To the Board of Directors and Stockholders of Quicksilver Resources Inc. Fort Worth, Texas We have audited the accompanying consolidated balance sheets of Terra Energy, Ltd.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997 - ------------------------------------------------------------------------------ 1. DESCRIPTION OF BUSINESS Terra Energy, Ltd. ("Terra") and its affiliates, Terra Pipeline Company ("TPC"), Kristen Corporation ("Kristen") and Energy Acquisition Company ("EAC"), are wholly owned subsidiaries of CMS Oil & Gas Company ("CMS"). CMS is a wholly owned subsidiary of CMS Energy Corporation ("CMS Energy"), located in Dearborn, Michigan. Terra, along with its named affiliates, is engaged in the acquisition, exploration, production and sale of natural gas, crude oil and condensate and the gathering, processing and transmission of natural gas. Terra currently has an interest in natural gas and crude oil mineral leases and hydrocarbon-producing wells that are located principally in the state of Michigan. The consolidated financial statements include the named affiliates, referred to collectively as the "Company." Investments in affiliated companies (20% to 50% owned) are accounted for using the equity method. Material intercompany transactions are eliminated in consolidation. 2. SIGNIFICANT EVENTS On March 5, 2000, CMS entered into a purchase and sale agreement with Quicksilver Resources Inc. ("Quicksilver"), whereby CMS agreed to sell substantially all of the assets of the Company and other CMS oil and gas properties in Michigan to Quicksilver for approximately $164 million, subject to adjustments. The agreement was effective as of January 1, 2000, and closed on March 31, 2000. 3. SIGNIFICANT ACCOUNTING POLICIES Cash and Cash Equivalents - The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Accounts Receivable - The Company's customers are large oil and natural gas purchasers. The Company does not require collateral, and receivables are generally due in 30 to 60 days. When collections of specific amounts due are no longer reasonably ensured, an allowance for doubtful accounts is established. Major Customers - At December 31, 1999, two purchasers accounted for approximately 80% and 10%, respectively, of the Company's total consolidated oil and gas sales. The Company does not anticipate that the loss of any of its present purchasers would adversely affect the Company's consolidated business. The Company also believes that, in the event of a loss of a present purchaser, other oil and gas purchasers located in the Company's areas of production would offer competitive prices for such production. Inventories - Inventories are valued at the lower of cost (first-in, first-out method) or market and consist of crude oil in tanks and well equipment spare parts and supplies. Properties, Plant and Equipment - The Company's oil and gas producing activities are accounted for using the successful efforts method of accounting in accordance with Statement of 13 Financial Accounting Standards ("SFAS") No. 19, "Financial Accounting and Reporting by Oil and Gas Producing Companies." In accordance with SFAS No. 19, the Company capitalizes the cost of property acquisitions, successful exploratory wells, all development costs, and support equipment and facilities when incurred. It expenses unsuccessful exploratory wells when they are determined to be nonproductive. The Company also charges to expense production costs, overhead and all exploration costs other than exploratory drilling as incurred. Depreciation, Depletion and Amortization - Depreciation and depletion of producing oil and gas properties are computed using the unit-of-production method based on estimated proved developed reserves determined by the Company's petroleum engineers. Office, computer and automotive equipment is depreciated using the straight-line method over estimated lives ranging from 5 to 10 years. In accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the future anticipated cash flow expected to be generated by an asset is compared to the carrying value of that asset. If the expected cash flow exceeds the carrying value of the asset, no adjustment is required. If the carrying value exceeds the future cash flow, the carrying value is reduced to reflect impairment. The impairment loss is recorded as an expense in the current period. The Company recorded impairment expenses of $720,000 during 1999, which is included in depletion, depreciation and amortization. Joint Venture Operations - Certain of the Company's exploration and development activities relating to oil and gas are conducted jointly with others. The accompanying consolidated financial statements reflect only the Company's proportionate interest in such activities. Revenue Recognition - The Company recognizes revenue as quantities of oil and gas are sold or volumes of gas are transported to the buyer, and utilizes the sales method of accounting for oil and gas imbalances. The Company's net imbalance was immaterial at December 31, 1999. Environmental Compliance and Remediation - Environmental compliance costs, including ongoing maintenance and monitoring, are expensed as incurred. Environmental remediation costs, which improve the condition of a property, are capitalized. Income Taxes - Deferred taxes are established for all temporary differences between the book and the tax basis of assets and liabilities at rates that will be in effect in the years the temporary differences are expected to reverse. Disclosure of Fair Value of Financial Instruments - The Company's financial instruments include cash and cash equivalents, accounts receivable, notes receivable, accounts payable and long-term debt. The carrying amounts reflected in the consolidated balance sheets for financial assets and the carrying amounts for financial liabilities approximate fair value due to the maturities, nature and interest rates of such instruments. Accounting Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Comprehensive Income - Comprehensive income is the same as net income. 14 REcently Issued Accounting Standards - The Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" which is effective for fiscal years beginning after June 15, 2000. This statement establishes accounting and reporting standards for derivative instruments and for hedging activities. 4.

SUPPLEMENTAL INFORMATION (UNAUDITED) Supplemental Information for Oil and Gas Producing Activities (Unaudited) - Proved oil and gas reserves have been estimated by Quicksilver's independent petroleum engineers as of January 1, 2000, and by CMS Oil & Gas Company's independent petroleum engineers at January 1, 1999, 1998 and 1997, in accordance with guidelines established by the Securities and Exchange Commission ("SEC"). Accordingly, the following reserve estimates are based upon economic and operating conditions existing as of each date. There are numerous uncertainties inherent in establishing quantities of proved reserves. The following reserve data represent estimates only and should not be construed as being exact. In addition, the present values should not be construed as the current market value of the Company's oil and gas properties or the cost that would be incurred to obtain equivalent reserves. Estimated Reserves - Changes in the estimated net quantities of crude oil and natural gas reserves, all of which are located in the continental United States, are as follows: Reserve Quantities Gas Oil (Mmcf) (Mbbl) Proved reserves: As of January 1, 1997 109,191 109 Revision of estimates 6,810 (49) Production for 1997 (6,831) (18) ------- --- As of January 1, 1998 109,170 42 Revision of estimates (23,729) (17) Production for 1998 (6,433) (14) ------- --- As of January 1, 1999 79,008 11 Revision of estimates 97,139 513 Production for 1999 (6,178) (11) ------- --- As of January 1, 2000 169,969 513 ======= === Proved developed reserves: As of January 1, 1997 105,536 109 As of January 1, 1998 101,614 42 As of January 1, 1999 78,439 11 As of January 1, 2000 140,585 513 18 The significant revision of estimates for the change in the estimated natural gas reserves in 1998 is primarily due to the decline in gas prices during 1998, making it uneconomical for the Company to produce those reserves. The revision of estimates in 1999 is a result of significant proved developed and proved undeveloped reserves estimated to be produced subsequent to 2014. Standardized Measure - The following tables present the Company's standardized measure of discounted future net cash flows and changes therein relating to proved oil and gas reserves and were computed using reserve valuations based on regulations prescribed by the SEC. These regulations provide that the oil, condensate and gas price structure utilized to project future net cash flows reflects current prices at each date presented and has been escalated only when known and determinable price changes are provided by contract. Future production, development and net abandonment costs are based on current costs without escalation. The resulting net future cash flows have been discounted to their present values based on a 10% annual discount factor for the years ended December 31, 1999, 1998 and 1997, as follows (in thousands). 1999 1998 1997 Future cash flows $ 394,529 $174,700 $ 277,606 Future production and development costs (209,305) (94,449) (129,536) Future income tax expense (62,976) (27,285) (50,344) --------- -------- --------- Future net cash flows 122,248 52,966 97,726 10% annual discount for estimated timing of cash flows (60,722) (19,728) (41,088) --------- -------- --------- Standardized measure of discounted future net cash flows $ 61,526 $ 33,238 $ 56,638 ========= ======== ========= Changes in Standardized Measure of Discounted Future Net Cash Flows 1999 1998 1997 Net changes in price and production costs $ (7,472) $(25,438) $(61,928) Revision of estimates 57,982 (20,000) 6,449 Changes in estimated future development costs 5,934 8,348 (2,755) Net change in income taxes (14,573) 12,055 20,711 Sales of oil and gas, net of production costs (9,757) (8,534) (10,121) Accretion of discount 3,324 5,664 9,684 Other (7,150) 4,505 (2,244) -------- -------- -------- Net increase (decrease) $ 28,288 $(23,400) $(40,204) ======== ======== ======== Estimated future cash inflows are computed by applying year-end prices of oil and gas to year-end quantities of proved reserves. Estimated future development and production costs are determined by estimating the expenditures to be incurred in developing and producing the proved oil and gas reserves in future years, based on year-end costs and assuming continuation of existing economic conditions. 19 These estimates are furnished and calculated in accordance with requirements of the FASB and the SEC. Because of unpredictable variances in expenses and capital forecasts, crude oil and natural gas price changes, and the fact that the bases for such estimates vary significantly, management believes the usefulness of these projections is limited. Estimates of future net cash flows do not necessarily represent management's assessment of future profitability or future cash flows to the Company. Costs incurred in oil and gas property acquisition, exploration and development activities for the years ended December 31, 1999, 1998 and 1997, totaled $1,536, $7,397 and $2,964, respectively, in thousands. Capitalized costs for oil and gas properties at December 31, 1999, 1998 and 1997, are as follows (in thousands): 1999 1998 1997 Proved oil and gas properties $ 68,901 $66,629 $ 70,964 Unproved oil and gas interests 4,004 6,725 3,382 Accumulated depletion and depreciation (16,682) (9,100) (12,369) -------- ------- -------- Total $ 56,223 $64,254 $ 61,977 ======== ======= ======== Results of operations from producing activities for the years ended December 31, 1999, 1998 and 1997, are as follows (in thousands): 1999 1998 1997 Oil and gas sales $13,413 $12,502 $13,823 Operating expenses (3,656) (3,968) (3,702) Depletion and depreciation (5,022) (4,076) (5,211) ------- ------- ------- 4,735 4,458 4,910 Income taxes 170 (661) (1,791) ------- ------- ------- Results of operations from producing activities (excluding corporate overhead and interest costs) $ 4,905 $ 3,797 $ 3,119 ======= ======= ======= * * * * * * 20 CONDENSED PRO FORMA STATEMENTS OF INCOME FOR THE THREE MONTHS ENDED MARCH 31, 2000 AND THE TWELVE MONTHS ENDED DECEMBER 31, 1999 (In thousands) - ------------------------------------------------------------------------------- On March 31, 2000, the Company completed the acquisition from CMS Oil & Gas Company, a subsidiary of CMS Energy Corporation, of CMS properties located primarily in Michigan for $164 million, subject to subsequent adjustments. The CMS properties consist of interests in approximately 3,050 gross (650 net) producing oil and gas wells located on approximately 512,000 gross (450,000 net) acres. Holditch-Reservoir Technologies Consulting Services, a Schlumberger company, estimated proved reserves attributable to the CMS acquisition of 315.1 Bcf of natural gas and 747.8 Mbbls of crude oil and condensate, and 143.9 Mbbls of natural gas liquids, or a total of 320.4 Bcfe with an estimated SEC PV-10 value as of January 1, 2000 of $184.0 million. Approximately 81% of the proved reserve volumes is classified as proved developed. Current daily production from the CMS properties is estimated to be 49 Mmcfe. Financing for the acquisition was accomplished through restructuring Quicksilver's senior bank facility, the sale of $43 million in Subordinated Notes, and the monetization of $25 million of the accompanying Section 29 tax credits to a major financial institution. The acquisition was accounted for under the purchase accounting method, and consists of both CMS producing properties as well as common stock of Terra Energy Ltd. The following summary pro forma financial information gives the effect of the acquisition on the Company's historical income statements as though the acquisition had occurred at the beginning of the periods presented. Adjustments were made to reflect a combined depletion rate, incremental general administrative expense and interest expense on acquisition debt.
