ExxonMobil Announces Production Start-up of Jasmim Deepwater Angolan Field

Exxon Mobil Corporation (NYSE:XOM) announced today the start-up of Jasmim oil
field production in Angola's deepwater offshore area known as Block 17.

Jasmim, operated by Total, is located approximately 95 miles (150 kilometers)
northwest of Luanda in water depths of 4,600 feet (1,400 meters). Discovered in
April 2000, Jasmim is one of fifteen discoveries announced in Block 17 and the
second to be brought on stream following Girassol in December of 2001. The
Jasmim development consists of eight sub-sea wells tied back to the Girassol
Floating, Production, Storage and Offloading (FPSO) vessel.

Jasmim will increase production on Block 17 to at least 230,000 barrels of oil a
day to the Girassol FPSO and prolong the production plateau. It is an integral
part of the growth strategy for Block 17 production.

ExxonMobil's subsidiary, Esso Exploration Angola (Block 17) Limited, has a 20
percent interest in the Jasmim development with coventurers Total E&P Angola
(operator 40 percent), BP (16.67 percent), Statoil (13.33 percent), and Norsk
Hydro (10 percent). Sonangol is the concessionaire for the block.
