ChevronTexaco Information Technology Company President and CIO Dave Clementz to Retire; Company Names Gary Masada to the Position

SAN RAMON, Calif., Jul. 21, 2003 -- David M. Clementz, president and chief information officer of Information Technology Company for ChevronTexaco Corp., has elected to retire effective July 31 after 30 years of service, the company announced today. Clementz is responsible for providing computing and telecommunications technology services worldwide.

Gary M. Masada, currently president of Energy Research and Technology for ChevronTexaco Corp., will replace Clementz. He manages technical capabilities in process and equipment technology, process planning, laboratory technology, catalysis and health, environment and safety for upstream and downstream operating companies.

Prior to being named president and chief information officer in 2001, Clementz was president of Chevron Information Technology Company (CITC), a position he assumed in 1997. At CITC, he led an organization of approximately 1,500 employees and managed worldwide information technology functions.

"At ChevronTexaco, it's impossible to talk about information technology without mentioning Dave," said Dave O'Reilly, ChevronTexaco chairman and chief executive officer. "He led the company through a major transformation with his vision of how information technology should be used to make our company a leader in the field. We will miss him."

"Gary Masada brings with him an in-depth understanding of our downstream operations and how technology is applied to complex manufacturing and control processes," said Don Paul, vice president and chief technology officer of ChevronTexaco. "With his well-known work-force planning and human relations experience, Gary will help ChevronTexaco continue as an industry leader in Information Technology."

Clementz joined the company in 1973 as a research chemist at Chevron Oil Field Research Co. (COFRC). In the early 1980s, Clementz was a production engineer for Chevron U.S.A. Inc. and later returned to COFRC as assistant to the president. From 1985 to 1990, he held management positions in reservoir engineering at COFRC.

In 1990, he was named manager of engineering for Chevron Canada Resources in Calgary, Alberta. In 1992, he took part in a study that resulted in the formation of Chevron Petroleum Technology Co. (CPTC), where he was appointed vice president and general manager of technology management and planning. Clementz was elected president of CPTC in November 1994.

A native of Cleveland, Ohio, Clementz has a bachelor's degree from the University of Arizona, a master's degree in business administration form Pepperdine University, a master's degree in science from Purdue University and a doctorate in soil science from Michigan State University.

Gary Masada joined Chevron as a research chemist in 1972. He went on to hold various technical positions at Chevron Research Co. (CRC) until 1978 when he transferred to Chevron U.S.A. operations and planning. After a variety of assignments of increasing responsibility, Masada was promoted in 1981 to group leader of distillate process for CRC and, in 1982, was named manager of hydroprocessing.

In 1989, when CRTC was formed, Masada was named group manager of the lubricants and specialties unit. During this time, Masada was involved in, or championed, various human resources-related issues -- including the performance management process, the technical career ladder, the upward feedback process and the quality functional deployment to develop new products.

In 1994, he was named manager of work-force planning and development of human resources for the corporation. In this position, he served as secretary of the management development committee for the corporation. He was named President of CRTC in 1998 and assumed his current position upon the formation of ChevronTexaco Corp., Oct. 9, 2001.

Masada was born in Granada, Colo., and raised in California. He earned a bachelor's degree in chemistry from the University of California at Berkeley in 1966. He obtained a doctorate degree in organic chemistry from the University of Washington in 1972.

He is a member of the American Chemical Society and the Conference Board of Operating Executives. Additionally, Masada serves on the Advisory Boards of the College of Chemistry and the Lawrence Hall of Science at the University of California, Berkeley, as well as on the Advisory Board of the Department of Chemical Engineering at the University of California, Santa Barbara.
