Rosneft and ExxonMobil to Join Forces for Development of Arctic and Black Sea Resources, Expand Technology Sharing and Implement Joint International Projects

Rosneft and ExxonMobil have executed a Strategic Cooperation Agreement
under which the companies plan to undertake joint exploration and
development of hydrocarbon resources in Russia, the United States and
other countries throughout the world, and commence technology and
expertise sharing activities.

The agreement, signed by Rosneft President Eduard Khudainatov and
ExxonMobil Development Company President Neil Duffin in the presence of
Russian Prime Minister Vladimir Putin, includes approximately US $3.2
billion to be spent funding exploration of East Prinovozemelskiy Blocks
1, 2 and 3 in the Kara Sea and the Tuapse License Block in the Black
Sea, which are among the most promising and least explored offshore
areas globally, with high potential for liquids and gas.

In the course of these projects, the companies will use global best
practices to develop state-of-the-art safety and environmental
protection systems.

The agreement also provides Rosneft with an opportunity to gain equity
interest in a number of ExxonMobil′s exploration opportunities in North
America, including deep-water Gulf of Mexico and tight oil fields in
Texas (USA), as well as additional opportunities in other countries. The
companies have also agreed to conduct a joint study of developing tight
oil resources in Western Siberia.

The companies will create an Arctic Research and Design Center for
Offshore Developments in St. Petersburg, which will be staffed by
Rosneft and ExxonMobil employees. The center will use proprietary
ExxonMobil and Rosneft technology and will develop new technology to
support the joint Arctic projects, including drilling, production and
ice-class drilling platforms, as well as other Rosneft projects.

'We have a clear vision for Rosneft′s strategic direction ? building
world-class expertise in offshore business and enhancing oil recovery,?
said Rosneft president Eduard Khudainatov, following the signing
ceremony. 'The partnership between Rosneft with its unique resource
base, and the largest and one of the most highly capitalized companies
in the world reflects our commitment to increasing capitalization of our
business through application of best-in-class technology, innovative
approach to business management, and enhancement of our staff potential.
This venture comes as a result of many years of cooperation with
ExxonMobil and brings Rosneft into large scale world-class projects,
turning the company into a global energy leader.'

ExxonMobil Development Company President Neil Duffin said: 'Today's
agreement with Rosneft builds on our 15-year successful relationship in
the Sakhalin-1 project. Our technology, innovation and project execution
capabilities will complement Rosneft′s strengths and experience,
especially in the area of understanding the future of Russian shelf
development.?

Rex Tillerson, chairman and chief executive officer of Exxon Mobil
Corporation (NYSE:XOM), who attended the ceremony, said ExxonMobil will
benefit Russian energy development by working closely with Rosneft.

'This large-scale partnership represents a significant strategic step by
both companies,? said Tillerson. 'This agreement takes our relationship
to a new level and will create substantial value for both companies.?

The agreement provides for constructive dialogue with the Russian
Federation government concerning creation of a fiscal regime based on
global best practices.

Additionally Rosneft and ExxonMobil will implement a program of staff
exchanges of technical and management employees which will help
strengthen the relationships between the companies and provide valuable
career development opportunities for personnel of both companies.
