CALLON PETROLEUM COMPANY Date NOVEMBER 21, 1997 By: /s/ JOHN S. WEATHERLY John S. Weatherly, Senior Vice President, Chief Financial Officer and Treasurer PAGE F-1 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Shareholders of Callon Petroleum Company We have audited the accompanying statement of revenues and direct operating expenses of 61% of Chevron U.S.A. Inc.'s working interest in Mobile 864 Unit Outer Continental Shelf (the "Property") acquired by Callon Petroleum Operating Company (the "Company"), a wholly owned subsidiary of Callon Petroleum Company, for each of the three years in the period ended December 31, 1996. This statement is the responsibility of the Company's management. Our responsibility is to express an opinion on this statement based on our audit. We conducted our audit in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of revenues and direct operating expenses is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of revenues and direct operating expenses. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the statement of revenues and direct operating expenses. We believe that our audit provides a reasonable basis for our opinion. The accompanying statement of revenues and direct operating expenses was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission (for inclusion in the registration statement on Form S-2 of Callon Petroleum Company) as described in Note 1 and is not intended to be a complete presentation of the Property's revenues and expenses. In our opinion, the statement of revenues and direct operating expenses referred to above presents fairly, in all material respects, the revenues and direct operating expenses of the Property described in Note 1 for each of the three years in the period ended December 31, 1996, in conformity with generally accepted accounting principles.

PAGE F-3 NOTES TO STATEMENT OF REVENUES AND DIRECT OPERATING EXPENSES OF THE PROPERTY (in thousands) 1. BASIS OF PRESENTATION Callon Petroleum Operating Company (the "Company"), a wholly owned subsidiary of Callon Petroleum Company, agreed in October 1997 to acquire 61% of Chevron U.S.A. Inc.'s working interest in Mobile 864 Unit Outer Continental Shelf which includes the twelve-inch Mobile 908 Area Gathering Pipeline (the "Property") for $21 million, effective July 1, 1997. The acquisition closed on November 7, 1997 for a net acquisition cost of $18.8 million. The accompanying statement of revenues and direct operating expenses relates only to the working interest in the producing oil and gas property acquired and may not be representative of future operations. The statement includes revenues from natural gas sales and direct operating expenses for each of the periods presented. The statement does not include federal and state income taxes, interest, depletion, depreciation and amortization or general and administrative expenses because such amounts would not be indicative of those expenses which would be incurred by the Company. Presentation of complete historical financial statements for each of the three years ended December 31, 1996 and the nine months ended September 30, 1997 is not practicable because the Property was not accounted for as a separate entity; therefore, such statements are not available. Revenues in the accompanying statement of revenues and direct operating expenses are recognized on the entitlement method. The accompanying statement has been prepared on the accrual basis in accordance with generally accepted accounting principles. Preparation of the statement in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the statement and accompanying notes. Actual results could differ from those estimates. The interim revenues and direct operating expenses for the nine months ended September 30, 1997 are unaudited; however, in the opinion of the Company, the interim revenues and direct operating expenses include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim period. 2. COMMITMENTS AND CONTINGENCIES In the normal course of business the Company is subject to possible loss contingencies arising from federal, state and local environmental, health and safety laws and regulations, joint venture audit claims and third party litigation. There are no matters which, in the PAGE F-4 NOTES TO STATEMENT OF REVENUES AND DIRECT OPERATING EXPENSES OF THE PROPERTY (in thousands) opinion of management, will have a material adverse effect on the revenues and direct operating expenses of the Property. 3. RELATED PARTY TRANSACTIONS The Property was not operated as a separate entity for the periods presented in the accompanying statement, but was included in the operations of Chevron U.S.A. Inc. Effective September 1, 1996, all revenues from production were transferred to an equity affiliate of Chevron Corporation, the parent of Chevron U.S.A. Inc., at approximate market prices. 4. SUPPLEMENTAL OIL AND GAS RESERVE DATA (UNAUDITED) The Property's proved oil and gas reserves at December 31, 1996, 1995 and 1994 have been estimated by the Company's independent petroleum consultants in accordance with guidelines established by the Securities and Exchange Commission ("SEC"). 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 Property or the cost that would be incurred to obtain equivalent reserves. PAGE F-5 NOTES TO STATEMENT OF REVENUES AND DIRECT OPERATING EXPENSES OF THE PROPERTY (in thousands) ESTIMATED RESERVES Changes in the estimated net quantities of natural gas reserves are as follows: GAS NET PROVED RESERVES OF NATURAL GAS (MMCF) ------- PROVED DEVELOPED AND UNDEVELOPED RESERVES AT: December 31, 1993 ......................................... 34,396 Production ................................................

These regulations provide that the gas price structure utilized to project future net cash flows reflects current prices at each date presented. Future production, development and net abandonment costs are based on current costs without escalation. Estimated future income taxes are calculated by applying appropriate year-end statutory tax rates. These rates reflect allowable deductions and tax credits and are applied to estimated future pre-tax net cash flows, less the tax basis of related assets. The resulting net future cash flows have been discounted to their present values based on a 10% annual discount factor.

BASIS OF PRESENTATION In October 1997, the Company agreed to purchase 61% of Chevron U.S.A. Inc.'s interest in the Mobile Block 864 Area (the "Chevron Acquisition") for $21 million effective July 1, 1997. The Chevron Acquisition closed on November 7, 1997 for a net purchase price of $18.8 million. In June 1997, Callon Petroleum Operating Company purchased a Working interest in the Mobile Area Block Unit from Elf Exploration, Inc. (the "Elf Acquisition") for a net purchase price of $11.8 million The accompanying Pro Forma Consolidated Statements of Operations of the Company for the year ended December 31, 1996 and the nine months ended September 30, 1997 give effect to the Elf Acquisition and the Chevron Acquisition as if the transactions occurred at the beginning of the earliest period presented. The effect of the Elf Acquisition detailed in the Pro Forma Consolidated Statements of Operations of the Company for the nine months ended September 30, 1997, includes only that portion of the Elf Acquisition up to the date of purchase. Amounts related to the Elf Acquisition after the date of purchase are included in the operations of the Company. The accompanying Pro Forma Consolidated Balance Sheet at September 30, 1997 gives effect to the Chevron Acquisition and the Elf Acquisition as if the transactions occurred on September 30, 1997. The Pro Forma Consolidated Balance Sheet and Statements of Operations are based on the assumptions set forth in the Notes to such statements. Such pro forma information should be read in conjunction with the related financial information of the Company and is not necessarily indicative of the results which would actually have occurred had the transaction been in effect on the date or for the period indicated or which may occur in the future. PAGE F-13 2. PRO FORMA ADJUSTMENTS Pro Forma entries necessary to adjust the historical financial statements of the Company are as follows: (a) To reflect the Elf Acquisition and the related results of operations as described in Note 1. (b) To reflect the Chevron Acquisition and the related results of operations as described in Note 1. (c) Reflects an increase of interest expense related to the purchase of the Chevron Acquisition as if the transaction had occurred at the beginning of the year ended December 31, 1996. The estimated interest rate used was 8.5%. A one-eighth change in this estimated rate would affect interest expense by $40,000 and $20,000 for the year ended December 31, 1996 and the nine months ended September 30, 1997, respectively. (d) To record a provision for Federal income taxes at a corporate statutory rate of 35% on pro forma income as a result of the acquisition (e) To adjust depletion for the combined full cost pool based on the purchase of the Chevron Acquisition as described in Note 1.
