SUPPLEMENTARY OIL AND GAS INFORMATION (Unaudited) Estimated Net Quantities of Proved Reserves 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. The following pro forma historical data as of December 31, 1994 gives effect to the acquisition of the Pennzoil Properties. Pennzoil Properties Company (Historical) Pro Forma Proved Reserves Crude Oil, Condensate and Natural Gas Liquids (Barrels) 6,153,100 994,365 7,147,465 Natural Gas (Thousands of Cubic Feet) (MCF) 14,951,400 6,489,229 21,440,629 SUPPLEMENTARY OIL AND GAS INFORMATION (Unaudited) (continued) Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Reserves The following table sets forth the computation of the standardized measure of discounted future net cash flows relating to proved reserves, estimated by the Company as of December 31, 1994. Future cash inflows represent expected revenues from production of proved reserves based on December 31, 1994 prices and any fixed and determinable future escalation provided by contractual arrangements in existence at that date. Escalation based on inflation and supply and demand are not considered. Estimated future production and development costs related to future production of proved reserves are based on December 31, 1994 costs. Future income tax estimates are included based on tax rates currently in effect. A discount rate of 10% is applied to the annual future net cash flows. The methodology and assumptions used in calculating the standardized measure are those required by Statement of Financial Accounting Standards No. 69. This data is not intended to be representative of the fair market value of the properties' proved reserves. The valuation of revenues and costs do not necessarily reflect the amounts to be received or expended. In addition to the valuations used, numerous other factors are considered in evaluating known and prospective oil and gas reserves.
