FOR IMMEDIATE RELEASE

                        DAVE O'REILLY TO SUCCEED KEN DERR
                         AS CHAIRMAN AND CEO OF CHEVRON

SAN FRANCISCO,  Sept. 29 -- The Chevron Corp. Board of Directors today announced
that Vice  Chairman  Dave  O'Reilly has been  elected  chairman of the board and
chief executive  officer,  effective  January 1. O'Reilly,  52, will succeed Ken
Derr,  63, who has elected to retire after a  distinguished  career of almost 40
years with the company, including 11 years as chairman and CEO.
         Dick Matzke,  62, a member of the Board of Directors  and  president of
Chevron Overseas Petroleum Inc. (COPI),  will succeed O'Reilly as vice chairman,
responsible for worldwide exploration and production operations.
         Jim Sullivan,  62, continues as vice chairman responsible for worldwide
refining, marketing and chemical operations.
         "Dave O'Reilly is the right person to lead Chevron in the future," said
Derr. "He combines broad company  experience with a record of achieving superior
business results, and he has strong leadership  skills."Born in Dublin, Ireland,
O'Reilly earned his bachelor's  degree in chemical  engineering  from University
College, Dublin in 1968. That year, he began his career with Chevron Research as
a process engineer.
         Serving in  positions  of  increasing  responsibility,  O'Reilly  later
became manager of Chevron's Salt Lake City Refinery,  manufacturing  manager for
Chevron Chemical's  Olefins Division,  and general manager of Chevron's refinery
in El Segundo,  Calif.  In 1989, he was elected  senior vice president and chief
operating officer of Chevron Chemical Co.
         O'Reilly was elected a vice president of Chevron Corp. in October 1991,
responsible for strategic  planning and  coordination  of the company's  quality
improvement activities. He also served as a director of Caltex Petroleum Corp.
         In September  1994, he was elected  president of Chevron  Products Co.,
where he led the company's U.S.  refining and marketing  operations.  During his
tenure,  U.S.  refining and marketing  earnings rose from $75 million in 1995 to
$633 million in 1998.
         In November  1998,  O'Reilly was elected a vice  chairman and director,
responsible for Chevron's worldwide  exploration and production  activities.  He
has also  been  leading  the  successful  effort to reduce  the  company's  cost
structure by $500 million.
         O'Reilly is a member of the  American  Petroleum  Institute's  board of
directors;   the  board  of  the  national  Action  Council  for  Minorities  in
Engineering,  Inc.;  the  California  Business  Roundtable and the San Francisco
Symphony Board of Governors.

        Matzke is a native of Illinois  and a graduate of Iowa State  University
(bachelor's  degree,  geology,  1959);  Pennsylvania State University  (master's
degree,  geology,  1961); and St. Mary's College of California (master's degree,
business administration, 1977).
        He joined  Chevron in 1961 as a  geologist  in  Louisiana  and  advanced
through  positions of responsibility  in the company's  exploration,  economics,
research and  corporate  planning  departments.  He was named  general  manager,
foreign  operations  staff, and director of Caltex Pacific Indonesia in 1982. In
1986, he was named president of Chevron Canada Resources Ltd.
         Matzke  was named  president  of COPI in 1989 and a vice  president  of
Chevron Corp. in 1990. He played a key  leadership  role in expanding  Chevron's
international presence in exploration and production, resulting in a doubling of
international oil production volumes during the past decade.
         In his new position,  he will be  responsible  for Chevron's  worldwide
upstream activities, with a primary emphasis on formulating and implementing the
growth component of the company's exploration and production strategies.
         Matzke was elected to the Chevron  Board of  Directors  in 1997.  He is
chairman  of the Board of  Directors  of the United  States-Kazakhstan  Business
Association,  a  member  of the  United  States-Russia  Business  Council,  vice
chairman of the United  States-Azerbaijan  Chamber of Commerce,  and a member of
the Business Council for International Understanding.  He serves on the Board of
Trustees of The Africa America  Institute,  and the Advisory Board of the Center
for Strategic and International Studies (CSIS).

                                      * * *
         Ken Derr has led Chevron  through a period of  unprecedented  financial
success as well as unparalleled  economic challenges.  Derr, who became chairman
and CEO in 1989, has brought a strong investor focus to Chevron's performance.
         During most of his tenure, the company led its oil competitors in total
shareholder return, a period when Chevron's market capitalization increased from
$15  billion to about $60  billion.  And the  company  has  increased  its stock
dividend for 10 consecutive years.
         Derr also brought an intense focus to efficient  operations.  Under his
leadership,  the company has  reduced  its annual cost  structure  by about $2.4
billion.
         Derr's tenure also saw Chevron sharply -- and  successfully -- increase
its  overseas  exploration  and  production  activities,  with two thirds of its
multi-billion-dollar capital budget now allocated outside of North America.
         Derr led the transition to international  activities when he signed the
first major joint venture  agreement in the Caspian Sea region with the Republic
of  Kazakhstan.  The Tengiz venture in  Kazakhstan,  which now produces  220,000
barrels of oil a day, is expected to more than triple  production  over the next
decade. During the same period, the company re-entered Venezuela,  Kuwait, Saudi
Arabia and Bahrain.
         A native of  Wilkes-Barre,  Pa.,  Derr  joined  Chevron  in 1960  after
earning a bachelors  degree in  mechanical  engineering  (1959) and a masters in
business administration (1960) from Cornell University.
         Derr has held positions of increasing authority, including assistant to
the president (1969), vice president (elected 1972), president of Chevron U.S.A.
Inc. (1979), and vice chairman (1985). Perhaps the highlight of his pre-chairman
tenure was his  successful  leadership  of the effort to implement all facets of
the 1984 merger of Chevron and Gulf  corporations,  the largest corporate merger
at that time in American history.
         Derr is a director of AT&T,  Citigroup,  Potlatch  Corp.,  the American
Productivity & Quality Center,  the Bay Area Council and the American  Petroleum
Institute,  which he also  served as  chairman.  He is a member of the  National
Petroleum Council, the Business Council and the Business Roundtable as well as a
Trustee Emeritus of Cornell University.  He also served as a member of President
Bush's  Commission  on  Environmental  Quality  and  as a  member  of  President
Clinton's Council on Sustainable Development.
         As chairman of the  fund-raising  Committee  to Save the San  Francisco
Cable Cars,  he led the  successful  effort to preserve  one of  America's  most
recognizable civic symbols.

FOR IMMEDIATE RELEASE

          ROBERTSON TO HEAD CHEVRON'S OVERSEAS OIL AND GAS OPERATIONS;
              KIRKLAND TO LEAD NORTH AMERICAN OIL AND GAS BUSINESS

         SAN FRANCISCO,  Sept. 29 -- Chevron today  announced the appointment of
Peter  Robertson  as  president  of  Chevron  Overseas  Petroleum  Inc.  (COPI),
replacing Dick Matzke, who was elected a Chevron vice chairman earlier today.
         COPI oversees Chevron's search for oil and production of oil and gas in
such key areas as Kazakhstan,  Angola,  Nigeria, the United Kingdom,  Australia,
Thailand and Latin America -- areas which  represent the most  promising  growth
prospects in Chevron's portfolio.
         Replacing  Robertson as president of Chevron North America  Exploration
and Production will be George Kirkland,  current chairman and managing  director
of Chevron Nigeria Ltd. Both appointments are effective Jan. 1.
         Kirkland,  49, has also been elected a corporation vice president,  and
Robertson will continue as a corporation vice president.
         Robertson, 52, is a native of Edinburgh, Scotland.  He earned  a
bachelor's degree in mechanical engineering at Edinburgh University, and he
holds an M.B.A. from the University of Pennsylvania, Wharton School.
         He joined Chevron in 1973, and after a variety of assignments was named
comptroller  for Chevron Oil Europe in London in 1980.  He then held several key
comptroller  posts before  being  elected vice  president,  finance,  of Chevron
U.S.A. in 1989.
         In  October  1991,  he was named  president  of Warren  Petroleum  Co.,
Chevron's former natural gas liquids subsidiary.  In 1994, he was elected a vice
president of Chevron Corp., responsible for strategic planning and the company's
total quality improvement activities. He also has served as a director of Caltex
Petroleum Corp.
         In 1997, he took on responsibility for Chevron's U.S. and Canadian
exploration and production operations.
         Robertson is on the board of directors of Dynegy Inc., a major  natural
gas and electric power marketer in which Chevron holds a 29 percent interest. He
is chairman of the  American  Petroleum  Institute's  Upstream  Committee  and a
member of the board of the Natural Gas Supply Association.
         Kirkland, a civil engineer,  joined Chevron 24 years ago and has worked
in North  America,  Asia and  Africa.  He began  his  career  as a  construction
engineer in 1974,  in New  Orleans,  La., and later spent six- years with Caltex
Pacific Indonesia,  where he served as project engineering manager for the giant
Duri steam flood project.
         At  various  times,  he  served  as senior  project  manager,  division
engineer,  chief engineer and  coordinator  of production  operations in Chevron
subsidiaries.
         For the past six years,  Kirkland has been with Chevron  Nigeria  Ltd.,
first as general  manager-production,  then as general manager-asset management.
In 1996, he was appointed chairman and managing director.  Under his leadership,
crude oil production  rose from  approximately  300,000 barrels per day (bpd) to
the  present  level of 440,000  bpd.  The  business  unit is  pursuing a plan to
increase it to 600,000 bpd by the year 2001.
         He has also  managed  successful  implementation  of the  Escravos  Gas
Project,  Nigeria's first major associated gas utilization plant, and has been a
leader in development of the proposed West Africa Gas Pipeline.
