ChevronTexaco and Western Refining Reach Definitive Agreement for Sale of El Paso Refinery

SAN RAMON, Calif., June 2, 2003 -- ChevronTexaco Corp. today announced a definitive agreement to sell its interest in its El Paso, Texas, refinery and certain associated assets to Western Refining Co., L.P.

Under the agreement, Chevron Products Co., a ChevronTexaco company, will also sell its El Paso light products terminal to Western Refining. Since 1993, Chevron Products and Western Refining have had an operating agreement whereby Chevron Products operates Western's part of the 90,000-barrel-per-day refinery complex. The sale does not include Chevron Products' El Paso asphalt plant.

Chevron Products will continue to market its branded gasoline, asphalt and other petroleum products throughout the area.

The agreement also calls for Chevron Pipe Line Co., a ChevronTexaco company, to sell an associated crude oil pipeline system to Kaston Pipeline Co., L.P., a subsidiary of Western Refining.

The sale is expected to close after all regulatory approvals and financing are obtained. Financial details of the agreement were not disclosed.

"While the El Paso Refinery has been an important part of our system for many years, our strategic focus is shifting," said Dave Reeves, president, Chevron Products Co. "This agreement advances our corporate objective of focusing investments in areas with the greatest potential for long-term growth and shareholder return, while enabling us to continue to provide our customers with premium products through our new business relationship with Western Refining."

Western Refining President and owner Paul Foster said, "It has been our desire for some time to buy the Chevron refinery and associated pipeline assets, and we look forward to being the owner and operator. Chevron and Western have had a great relationship and we look forward to our new business relationship."

Chevron's El Paso Refinery began operations in 1928. Approximately 270 people are employed at the refinery, light products terminal and crude oil pipeline system.
