ExxonMobil U.S. Marine Affiliate Announces Plan for Two New Tankers

Exxon Mobil Corporation′s U.S. marine affiliate, SeaRiver Maritime,
Inc., signed a letter of intent with Aker Philadelphia Shipyard, a
leading U.S. shipbuilding facility in Pennsylvania, for the construction
of two U.S. flag, crude oil tankers in partnership with Samsung Heavy
Industries, a leader in shipbuilding technologies. The vessels will be
used to transport Alaska North Slope crude oil from Prince William
Sound, Alaska to U.S. West Coast destinations.

Project planning work is underway with construction of the 115,000
deadweight ton tankers expected to begin by mid-2012. The vessels are
scheduled for delivery in 2014 and will be capable of carrying 730,000
barrels of crude oil to help meet U.S. energy needs. They will replace
two existing double hull tankers.

All cargo and fuel compartments will be equipped with double hull
protection. Both vessels will feature the latest in navigation and
communications equipment. Main engine and auxiliary systems will be
energy efficient and generate lower air emissions than what is required
by current regulatory standards.

'Today′s announcement is consistent with our long-term ongoing
commitment to safe and reliable marine transportation in the United
States and throughout the world,? said Will Jenkins, president of
SeaRiver. 'These new vessels will provide jobs for American shipyard
workers and help support energy needs along the U.S. West Coast for
decades to come.?

SeaRiver Maritime, Inc., headquartered in Houston, Texas, operates a
fleet of U.S. flag tankers and provides a wide range of technical and
commercial marine services to ExxonMobil affiliates throughout the world.
