The Board of Directors
Titan Exploration, Inc.:

     We have audited the accompanying statement of revenues and direct operating
expenses of the oil and gas properties acquired (Pioneer Acquisition) by Titan
Exploration, Inc. for the year 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 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
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 Form 8-K/A Amendment No. 1
of Titan Exploration, Inc. as described in Note 1) and is not intended to be a
complete presentation of the Pioneer Acquisition 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 Pioneer Acquisition for the year ended December
31, 1996, in conformity with generally accepted accounting principles.

       Notes to the Statements of Revenues and Direct Operating Expenses



(1)  Basis of Presentation

     On December 16, 1997, Titan Exploration, Inc. (the "Company") acquired from
       Pioneer Natural Resources USA, Inc. ("Pioneer") certain oil and gas
       properties (the "Pioneer Acquisition") for approximately $54.4 million.
       The accompanying statements of revenues and direct operating expenses for
       the Pioneer Acquisition do not include general and administrative
       expenses, interest income or expense, a provision for depreciation,
       depletion and amortization, or any provision for income taxes since
       historical expenses of this nature incurred by Pioneer are not
       necessarily indicative of the costs to be incurred by the Company.

     Historical financial information reflecting financial position, results of
       operations, and cash flows of the Pioneer Acquisition, are not presented
       because the purchase price was assigned to the oil and gas property
       interests acquired. Other assets acquired and liabilities assumed were
       not material. Accordingly, the historical statements of revenues and
       direct operating expenses of the Pioneer Acquisition are presented in
       lieu of the financial statements required under Rule 3-05 of Securities
       and Exchange Commission Regulation S-X.

     Revenues in the accompanying statements of revenues and direct operating
       expenses are recognized on the sales method. Under this method, revenues
       are recognized based on actual volumes of oil and gas sold to purchasers.
       Direct operating expenses are recognized on the accrual method.

     Interim Statements of Revenues and Direct Operating Expenses

     The interim financial information for the nine months ended September 30,
       1996 and 1997, is unaudited. However, in the opinion of management, the
       interim statements of revenues and direct expenses include all the
       necessary adjustments to fairly present the results of the interim period
       and all such adjustments are of a normal recurring nature. The interim
       statements of revenues and direct operating expenses should be read in
       conjunction with the audited statement of revenues and direct operating
       expenses for the year ended December 31, 1996.

(2)  Supplementary Financial Information for Oil and Gas Producing Activities
     (Unaudited)

     Estimated Quantities of Proved Oil and Gas Reserves

     Reserve information presented below for the Pioneer Acquisition, as of
       January 1, 1996 and December 31, 1996, is based on reserve estimates
       prepared by the Company, using prices and costs in effect at each date.
       Changes in reserve estimates were derived by adjusting such quantities
       and values for actual production using historical prices and costs.

                                                                     (Continued)

       Notes to the Statements of Revenues and Direct Operating Expenses



     Proved reserves are estimated quantities of crude oil and natural gas which
       geological and engineering data demonstrate with reasonable certainty to
       be recoverable in future years from known reservoirs under existing
       economic and operating conditions. Proved developed reserves are those
       which are expected to be recovered through existing wells with existing
       equipment and operating methods. Oil and gas reserve quantity estimates
       are subject to numerous uncertainties inherent in the estimation of
       quantities of proved reserves and in the projection of future rates of
       production and the timing of development expenditures. The accuracy of
       such estimates is a function of the quality of available data and of
       engineering and geological interpretation and judgment. Results of
       subsequent drilling, testing and production may cause either upward or
       downward revision of previous estimates. Further, the volumes considered
       to be commercially recoverable fluctuate with changes in prices and
       operating costs. The Company emphasizes that reserve estimates are
       inherently imprecise and that estimates of new discoveries are more
       imprecise than those of currently producing oil and gas properties.
       Accordingly, these reserve estimates are expected to change as additional
       information becomes available in the future.

     Below are the net estimated quantities of proved reserves and proved
       developed reserves for the Pioneer Acquisition:

     Standardized Measure of Discounted Future Net Cash Flows of Proved Oil and
     Gas Reserves

     The Company has estimated the standardized measure of discounted future net
       cash flows and changes therein relating to proved oil and gas reserves in
       accordance with the standards established by the Financial Accounting
       Standards Board through its Statement No. 69. The estimates of future
       cash flows and future production and development costs are based on year-
       end sales prices of $24.02 per Bbl for oil and $3.46 per Mcf for gas,
       estimated future production of proved reserves, and estimated future
       production and development costs of proved reserves, based on current
       costs and economic conditions. The estimated future net cash flows are
       then discounted at a rate of 10%

     Discounted future net cash flow estimates like those shown below are not
       intended to represent estimates of the fair market value of oil and gas
       properties. Estimates of fair market value should also consider probable
       reserves, anticipated future oil and gas prices, interest rates, changes
       in development and production costs and risks associated with future

                   DECEMBER 31, 1996 AND SEPTEMBER 30, 1997
                                        
NOTE 1.  BASIS OF PRESENTATION
 
         The unaudited pro forma combined financial statements have been
prepared to give effect to the 1996 Acquisition, the Pioneer Acquisition and the
OEDC Merger as if each transaction had taken place on September 30, 1997, with
respect to the unaudited pro forma combined balance sheet, and as of January 1,
1996, with respect to the unaudited pro forma combined statements of operations.
Each acquisition is recorded using the purchase method of accounting.

         Following is a description of the individual columns included in these
unaudited pro forma combined financial statements:

         TITAN  Represents the consolidated balance sheet of  Titan Exploration,

     NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS-(CONTINUED)
                   DECEMBER 31, 1996 AND SEPTEMBER 30, 1997
                                        


         (h) To adjust income tax expense.

         (i) To eliminate OEDC's preference units (redeemed in November 1996) 
and the related accretion of discount.

NOTE 3.  INCOME TAXES

         The Company accounts for income taxes pursuant to the provisions of
SFAS 109. At September 30, 1997, the pro forma book basis of the Company's
assets and liabilities exceeded the pro forma tax basis by approximately
$50,378,000 giving rise to an estimated deferred tax liability of approximately
$27,127,000. The temporary differences are primarily related to the differences
in book and tax basis of oil and gas properties due to the expensing of
intangible development costs for tax purposes and other income tax differences
arising from the tax treatment of oil and gas producing activities.

NOTE 4.  SUPPLEMENTAL OIL AND GAS RESERVE INFORMATION (UNAUDITED)

         The following unaudited pro forma supplemental information regarding
the oil and gas activities of the Company is presented pursuant to the
disclosure requirements promulgated by the Commission and Statement of Financial
Accounting Standards No. 69, "Disclosures About Oil and Gas Producing
Activities". The pro forma combined reserve information is presented as if the
OEDC Merger, Pioneer Acquisition, and the 1996 Acquisition had occurred on
January 1, 1996.

         Management emphasizes that reserve estimates are inherently imprecise
and subject to revision and that estimates of new discoveries are more imprecise
than those of producing oil and gas properties. Accordingly, the estimates are
expected to change as future information becomes available; such changes could
be significant.

Quantities of oil and gas reserves

         Set forth below is a pro forma summary of the changes in the net
quantities of oil and natural gas reserves for the year ended December 31, 1996.

Standardized measure of discounted future net cash flows

         The pro forma combined standardized measure of discounted future net
cash flows is computed by applying year-end prices of oil and gas (with
consideration of price changes only to the extent provided by contractual
arrangements) to the estimated future production of oil and gas reserves less
estimated future expenditures (based on year-end costs) to be incurred in
developing and producing the proved reserves, discounted using a rate of 10% per
year to reflect the estimated timing of the future cash flows. Future income
taxes are calculated by comparing discounted future cash flows to the tax basis
of oil and gas properties, plus available carryforwards and credits, and
applying the current tax rate to the difference.
