NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION 1. PRO FORMA ADJUSTMENTS The unaudited pro forma condensed consolidated financial information has been adjusted to reflect the following: a. The fair value of the Acquired Properties based on a preliminary purchase price of $146.0 million before final closing adjustments. The purchase price was funded using borrowings of $60.0 million from the Company's bank credit facility and the remainder was from cash on hand. In addition, this entry reflects the present value of asset retirement obligations assumed and a corresponding asset of approximately $274,000; b. Incremental depreciation, depletion, and amortization expense of $8.5 million, using the units-of-production method, resulting from the acquisition of the Acquired Properties including accretion expense related to the asset retirement obligation on the Acquired Properties of $20,616; c. Interest expense associated with debt of $60.0 million incurred under the Company's bank credit facility to fund the purchase price before consideration of final closing adjustments. The applicable average interest rate on the bank credit facility was approximately 2.15%; d. A pro forma income tax provision, assuming a 36% rate. 2. SUPPLEMENTAL PRO FORMA INFORMATION ON OIL AND NATURAL GAS OPERATIONS -- (UNAUDITED) The following pro forma supplemental information concerning the Company's proved oil and natural gas reserves is presented pursuant to the disclosure requirements of Statement of Financial Accounting Standards No. 69 "Disclosures About Oil and Gas Producing Activities." The following tables set forth the changes in the net quantities of oil and natural gas reserves of the Company and the Acquired Properties and the combined reserves on a pro forma basis giving effect to the acquisition as if it had occurred on January 1, 2004. There are numerous uncertainties inherent in estimating the quantities of proved reserves and projecting future rates of production and timing of development expenditures. The following reserve data represents estimates only and should not be construed as being exact: PROVED OIL AND NATURAL GAS RESERVES <Table> <Caption> CRUDE OIL (Mbbls) ACQUIRED EPL PROPERTIES PRO FORMA ------ ---------- --------- (IN THOUSANDS) Proved reserves at January 1, 2004 .................... 27,414 902 28,316 Extensions, discoveries and other additions ......... 3,231 337 3,568 Revisions ........................................... 1,296 70 1,366 Production ..........................................

NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION--(CONTINUED) The following table sets forth the components of the changes in the Standardized Measure of discounted future net cash flows from proved oil and natural gas reserves of the Company, the Acquired Properties and on a combined pro forma basis for the year ended December 31, 2004. Cash flows relating to the Acquired Properties are based on our evaluation of reserves and on information provided by Castex. The information should be viewed only as a form of standardized disclosure concerning possible future cash flows that would result under the assumptions used, but should not be viewed as indicative of fair market value. Reference is made to the Company's financial statements for the fiscal year ended December 31, 2004 included in its Form 10-K for a discussion of the assumptions used in preparing the information presented. The December 31, 2004 computation for the Acquired Properties was based on period-end prices of $6.60 per Mcf for natural gas and $42.46 per barrel for crude oil. The standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves is as follows: <Table> <Caption> ACQUIRED EPL PROPERTIES PRO FORMA ----------- ----------- ----------- (IN THOUSANDS) Future cash inflows .............................................................. $ 2,136,571 $ 354,137 $ 2,490,708 Future production costs ........................................................
