F-4 PRIMEENERGY CORPORATION NOTES TO PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1. Basis of Presentation On August 22, 2005, F-W Oil Exploration L.L.C. ("FWOE"), a subsidiary of PrimeEnergy Corporation, contributed and assigned certain oil and gas properties and pipelines, equipment, facilities and fixtures appurtenant thereto, in off-shore Gulf of Mexico (the "Properties") to FWOE Partners L.P. ("Partners"). In exchange for the Properties, FWOE received an initial 20% General Partnership interest in Partners and a cash distribution from Partners of $42.9 million, of which $25.2 million was used to repay outstanding bank debt and extinguish liens against the contributed properties. The cash distribution includes adjustments for estimated net revenues from the effective date of April 1, 2005, estimated capital expenditures and other typical closing adjustments. Post closing adjustments including final net revenues and capital expenditures will be made within 90 days. The accompanying pro forma consolidated financial statements have been prepared by recording pro forma adjustments to the historical consolidated financial statements of PrimeEnergy Corporation. The pro forma consolidated balance sheet as of June 30, 2005, has been prepared as if the transaction occurred on June 30, 2005. The pro forma consolidated income statement for the year ended December 31, 2004, has been prepared as if the transaction occurred on January 1, 2004. The pro forma consolidated income statement for the six months ended June 30, 2005 has been prepared as if the transaction occurred on January 1, 2005. 2. Pro Forma Adjustments Pro forma adjustments necessary to adjust the consolidated balance sheet for the disposition of the Properties are as follows: (a) To adjust for the net change in oil and gas properties and the receipt of the cash distribution from Partners. (b) To adjust for an estimated tax payment at statutory rates and the repayment of long-term bank debt. (c) To adjust the estimated asset retirement obligation related to the Properties. Pro forma adjustments necessary to adjust the consolidated income statements for the disposition of the Properties are as follows: (d) To adjust for the historical revenue and direct operating expenses related to the Properties. (e) To adjust for the estimated depreciation and depletion expense related to the Properties. (f) To adjust for the interest expense related to the repayment of long-term debt. (g) To adjust for income tax expense related to the Properties' operations. 3. Pro Forma Supplemental Oil and Gas Reserve Information Estimated Quantities of Pro Forma Proved Oil and Gas Reserves Pro forma reserve estimates at December 31, 2004, are based on reports prepared by independent petroleum engineers for proved reserves of PrimeEnergy Corporation using December 31, 2004, prices and costs. Proved reserves are estimated quantities of crude oil, natural gas and natural gas liquids which, based on geologic and engineering data, are estimated to be reasonably 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. Because of inherent uncertainties and the limited nature of reservoir data, such estimates are subject to change as additional information becomes available.

Such assumptions include the use of year-end prices for oil and gas and year-end costs for estimated future development and production expenditures to produce year-end estimated proved reserves. Discounted future net cash flows are calculated using a 10% rate. The standardized measure does not represent our estimate of future net cash flows or the value of proved oil and gas reserves. Probable and possible reserves, which may become proved in the future, are excluded from the calculations. Furthermore, year-end prices, used to determine the standardized measure of discounted cash flows, are influenced by seasonal demand and other factors and may not be the most representative in estimating future revenues or reserve data.
