                      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.

 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

   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

   STANDARDIZED MEASURE

   The following tables present the Property's standardized measure of
   discounted future net cash flows and changes therein relating to proved
   reserves and were computed using reserve valuations based on regulations
   prescribed by the SEC. 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.

           NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

1.     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.

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.
