Exhibit 99.1 The Premcor Refining Group Inc. Unaudited Pro Forma Combined Condensed Financial Statements The following unaudited pro forma combined condensed financial statements give effect to the restructuring described in Item 2 to this Current Report on Form 8-K. Certain of these pro forma statements, as described below, also give effect to a contribution to PRG from the proceeds of the Premcor Inc. initial public offering and application of those proceeds to redeem PRG's 9 1/2% senior notes due 2004, on June 3, 2002 (the "IPO related transactions"). The effects of the IPO related transactions were not part of the restructuring. However, the effects of the IPO related transactions have been included in certain of the unaudited pro forma combined condensed financial statements because they are not reflected in the historical financial statements and are considered material. The unaudited pro forma combined condensed balance sheet as of March 31, 2002 gives effect to the restructuring and IPO related transactions as if each had occurred on March 31, 2002. The unaudited pro forma combined condensed statements of operations for the quarter ended March 31, 2002 and the year ended December 31, 2001 give effect to the restructuring and IPO related transactions as if each had occurred on January 1, 2002 and January 1, 2001, respectively. The unaudited pro forma combined condensed statements of operations for the years ended December 31, 2000 and 1999 give effect to the combination of PRG and Sabine as if the combination had occurred on January 1st of the applicable year, but do not reflect transactions related to the restructuring or the IPO related transactions. The unaudited pro forma combined condensed financial statements are based on assumptions that PRG believes are reasonable under the circumstances and are intended for informational purposes only. These statements are not necessarily indicative of the financial position or future financial results of the combined companies or of the financial position or the results of operations that would have actually occurred had the restructuring and IPO related transactions taken place as of the date or for the periods presented. These unaudited pro forma combined condensed statements should be read in conjunction with Sabine's and PRG's Annual Reports on Form 10-K for the year ended December 31, 2001 and Quarterly Reports on Form 10-Q for the quarter ended March 31, 2002. The pro forma adjustments use estimates and assumptions based on currently available information. Management believes that the estimates and assumptions are reasonable, and that the significant effects of the transactions are properly reflected. However, actual results may differ from this pro forma information. The unaudited pro forma combined condensed statements of operations do not include the effects of nonrecurring charges related to the restructuring and IPO related transactions, which include the write-off of deferred charges and payments of premiums related to the early redemption of debt at both PRG and Sabine. These nonrecurring charges in the aggregate were $13.7 million ($8.8 million net of income taxes) as of March 31, 2002.

The $142.0 million in charges for the quarter ended March 31, 2002 included $131.2 million related to the announced discontinuation of refining operations at our Hartford refinery and $10.8 million primarily due to severance and other charges related to corporate restructuring. The $176.2 million in charges in 2001 included $167.2 million related to the closure of our Blue Island refinery and $9.0 million related to a write-off of idled coker units at the Port Arthur refinery. Adjusted EBITDA is presented because PRG believes it is a useful indicator to its investors of its ability to incur and service debt based on its ongoing operations. Adjusted EBITDA should not be considered by investors as an alternative to operating income or net income as an indicator of performance, nor as an alternative to cash flows from operating activities, investing activities or financing activities as a measure of liquidity. Because all companies do not calculate EBITDA identically, this presentation of adjusted EBITDA may not be comparable to EBITDA, adjusted EBITDA or other similarly-titled measures of other companies. (b) Represents the elimination of PRG's revenue and expense from intercompany transactions with PACC. (c) Represents the elimination of PACC's revenue and expense from intercompany transactions with PRG. (d) Represents interest expense and debt amortization costs of the 9 1/2% senior notes for the year ended December 31, 2001 and for the quarter ended March 31, 2002. (e) Represents the income tax effect of the adjustments relating to the redemption of our 9 1/2% senior notes at PRG's effective income tax rate of 39%. (f) Represents annual cost savings from cancellation of insurance policies and Sabine's working capital facility based on 2001 actual cost, offset by an estimated annual increase in letter of credit usage under PRG's amended working capital facility at 2.9% per annum. Amounts have been pro-rated for the quarter ended March 31, 2002. (g) Represents cost savings related to the elimination of independent director fees, two full-time equivalent employees and redundant trustee and rating agency fees. (h) Represents $29.5 million in annual interest expense savings, a $1.5 million reduction in annual debt amortization costs relating to the repayment of $287.6 million in senior secured bank loans based on the actual 2001 interest cost, and a net $0.4 million in annual cost savings representing the difference in the cost of Sabine's insurance policies and working capital facility versus an estimated increase in the amended working capital facility usage at 2.9% per annum. These savings are partially offset by a $2.2 million increase in amortization of the consent fees and other costs of the restructuring. Adjustments for the quarter ended March 31, 2002 are based on actual first quarter 2002 amounts. (i) Represents the income tax effect of the adjustments relating to the restructuring at Sabine's effective income tax rate of 35%. (j) Represents the elimination of intercompany profit between PRG and Sabine as of the year ended December 31, 2000 and the reversal of this elimination in the year ended December 31, 2001.
