Exxon Mobil Corporation

ExxonMobil Upstream Research Company announced today that it has licensed a
patented liquefied natural gas (LNG) storage tank technology to U.K.-based
Skanska Whessoe, a leading engineering, procurement and construction contractor
with specialized, worldwide experience in storage and handling of
low-temperature fluids. This new innovation in LNG storage technology, called
modular tanks, offers the potential for significant cost savings and faster
construction times for LNG import and export terminals.

The technology employs modern shipyard fabrication practices and a scalable,
modular design to provide a full-containment LNG storage system. The tanks have
been designed and rigorously evaluated for a wide range of conditions including
earthquake prone areas of the Pacific-rim, North America, and Europe.

ExxonMobil's modular tanks are fully compatible with the design standards and
criteria currently being considered for use at LNG import terminals worldwide.
To provide a high degree of safety, the inner, nickel/steel, and the outer,
reinforced, prestressed concrete tanks of the modular storage system are liquid
and gas tight, and independently capable of containing the stored LNG.

The modular LNG storage tank system is another example of ExxonMobil's extensive
LNG technology development program contributing to the company's expanding LNG
business. While currently participating in the production of about 20 percent of
the world's LNG, ExxonMobil is leveraging its LNG experience, technology and
worldwide gas marketing processes to rapidly grow its LNG portfolio.

Significant new applications of LNG technology are being planned for
ExxonMobil's joint venture projects with Qatar Petroleum that are developing
resources from Qatar's giant North field. These include the world's largest
liquefaction trains, each producing about 7.8 million tons annually (MTA) of
LNG, surpassing the current industry-record 4.7 MTA trains in RasGas II, which
is also a joint venture project between Qatar Petroleum and ExxonMobil. The LNG
from these large trains will be transported to market via a new generation of
very large LNG carriers.

ExxonMobil Upstream Research Company is the upstream research unit of Exxon
Mobil Corporation (www.exxonmobil.com), a leading global oil, natural gas and
petrochemicals company with operations in nearly 200 countries and territories.
ExxonMobil leads the industry in upstream technology development and
application.

From its U.K. base, Skanska Whessoe (www.skanska.co.uk) operates worldwide to
design and build tanks and terminals for the LNG/LPG market and is also in the
business of associated gas treatment, fluid handling and storage systems.

CAUTIONARY STATEMENT: Projections, estimates, expectations and business plans in
this release are forward-looking statements. Actual future results, including
technology application and project plans and schedules, and LNG production could
differ materially due to changes in market conditions affecting the oil and gas
industry; political actions; the outcome of commercial negotiations;
developments involving competing technologies; and other factors discussed in
our SEC filings. See in particular "Factors Affecting Future Results" under Item
1 of ExxonMobil's most recent Form 10-K. References to future quantities of LNG
reflect volumes that are not yet classified as proved reserves but that we
believe will ultimately be produced.
