                    PREMCOR COMPLETES COMMON STOCK OFFERINGS

     OLD GREENWICH, Connecticut, January 30, 2003 - Premcor Inc. (NYSE:PCO)
announced today that it has completed its public offering of 12,500,000 shares
of common stock at $20.00 per share. Additionally, in a private placement that
was completed concurrently with the closing of the public offering, an aggregate
of 2,860,400 shares were purchased at the public offering price less
underwriting commissions, or $19.20 per share, by affiliates of The Blackstone
Group L.P., affiliates of Occidental Petroleum Corporation, Thomas D. O'Malley,
the company's chairman and chief executive officer, and certain officers of the
company.

     Net proceeds from the public offering and the private placement aggregated
$293.9 million. Premcor expects to use these net proceeds, together with the net
proceeds from the recently announced $525 million Senior Notes offering by its
subsidiary, The Premcor Refining Group, Inc. ("PRG"), to finance the purchase
from The Williams Companies of its refinery and related supply and distribution
assets located in and around Memphis, Tennessee; to acquire certain Memphis
refinery inventory and other working capital assets; to repay $240 million in
principal amount of PRG's floating rate notes due 2003 and 2004; to redeem the
outstanding 11 1/2% Subordinated Exchange Debentures Due 2009 of its subsidiary,
Premcor USA Inc. for $42.2 million; and for general corporate purposes.

     The securities offered in the private placement will not be, and have not
been, registered under the Securities Act of 1933 and may not be offered or sold
in the United States absent registration or an applicable exemption from
registration requirements.

     Premcor Inc. is one of the largest independent petroleum refiners and
marketers of unbranded transportation fuels and heating oil in the United
States.

     This press release contains forward-looking statements within the meaning
