           BP AND TNK-BP PLAN STRATEGIC ALLIANCE WITH GAZPROM
             AS TNK-BP SELLS ITS STAKE IN KOVYKTA GAS FIELD

BP and TNK-BP today announced that they have signed a memorandum of
understanding to create a strategic alliance with the Russian gas giant,
Gazprom, to invest jointly in major long-term energy projects or swap assets
around the world.

In a move designed to extend Gazprom's access to international markets and
deepen BP and TNK-BP involvement in Russian oil and gas, the companies will
establish a joint team to identify strategic opportunities for investment both
overseas and inside Russia.

"We will initially be looking for projects of at least $3 billion, but the
potential for further growth could be very significant," said BP chief executive
Tony Hayward. "This historic agreement lays the ground for powerful co-operation
between BP, TNK-BP and Gazprom."

Dr Hayward said the companies would immediately set up a joint steering group to
look for suitable investment options "across all geographies."

"Our firm aim is to establish a venture that is strategic and long term, with
mutual benefits for the companies, both inside and outside Russia."

Under the terms of the agreement signed by all parties, TNK-BP agreed to sell
Gazprom its 62.89 per cent stake in Rusia Petroleum, the company which holds the
licence for the Kovykta gas field in East Siberia. It will also sell its 50 per
cent interest in East Siberian Gas Company (ESGCo), the company constructing the
regional gasification project.

Gazprom will pay between $700-$900 million, subject to adjustments, for TNK-BP's
interests in Rusia and ESGCo.

TNK-BP said a longer-term 'call' option for TNK-BP to buy a 25 per cent plus one
share stake in Kovykta at an independently verified market price, had also been
agreed with Gazprom. This option could be exercised once a significant joint
investment or asset swap has been agreed under the terms of today's memorandum
of understanding.

President and CEO of TNK-BP, Bob Dudley noted: "This is an important development
in the future growth of TNK-BP. We look forward to broadening our working
relationships with Gazprom and BP and to further developing our Russian asset
base as well as securing access to material additional opportunities for
TNK-BP."
