Item 2.    Acquisition or Disposition of Assets

         On June 6, 2002, The Premcor Refining Group Inc. ("PRG"), and Sabine
River Holding Corp. ("Sabine") completed a series of transactions ("the
restructuring") that resulted in Sabine and its subsidiaries becoming wholly
owned subsidiaries of PRG. Sabine, through its principal operating subsidiary,
Port Arthur Coker Company L.P. ("PACC"), owns and operates a heavy oil
processing facility, which is operated in conjunction with PRG's Port Arthur,
Texas refinery. Prior to the restructuring, Sabine was 90% owned by Premcor Inc.
and 10% owned by Occidental Petroleum Corporation. PRG is a wholly owned,
indirect subsidiary of Premcor Inc.

         The restructuring was permitted by the successful consent solicitation
of bondholders of Sabine's Port Arthur Finance Corp. 12 1/2% senior notes due
2009. The restructuring was accomplished according to the following steps, among
others:

...    Premcor Inc. contributed $225.6 million in proceeds from its initial public
     offering of common stock to Sabine. Sabine used the proceeds from the
     equity contribution, plus cash on hand to prepay $221.4 million of its
     senior secured bank loan and to pay a dividend of $141.4 million to Premcor
     Inc.;

...    Commitments under Sabine's senior secured bank loan, working capital
     facility, and certain insurance policies were terminated and related
     guarantees were released;

...    PRG's existing working capital facility was amended and restated to, among
     other things, permit letters of credit to be issued on behalf of Sabine;

...    Occidental Petroleum Corporation exchanged its 10% interest in Sabine for
     1,363,636 newly issued shares of Premcor Inc. common stock;

...    Premcor Inc. contributed its 100% ownership interest in Sabine to Premcor
     USA Inc., the parent company of PRG. Premcor USA Inc., in turn, contributed
     its 100% ownership interest to PRG; and

...    PRG fully and unconditionally guaranteed, on a senior unsecured basis, the
     payment obligations under the Port Arthur Finance Corp. 12 1/2% senior
     notes due 2009. The guarantee was issued in a private placement made in
     reliance on an exemption from the registration requirements of the
     Securities Act. PRG and Sabine have agreed to file a registration statement
     under the Securities Act to register the notes and the PRG guarantee, not
     later than 120 days from June 6, 2002.
