HOUSTON, August 28 /PRNewswire/ --

Endeavour International Corporation (Amex: END) announced today that its
subsidiary, Endeavour Energy Norge AS, has entered into an agreement with VNG
Norge AS in which VNG will acquire a 20 percent working interest in
production licenses PL 270 and PL 426 in Block 35/3 on the Norwegian
Continental Shelf. The area contains the Agat natural gas discovery in
addition to other drilling opportunities.

"We welcome VNG and its technical competencies to our partnership," said
William L. Transier, chairman, chief executive officer and president. "As
operator with a controlling interest in the block, we are committed to
realizing as soon as possible the full potential of this area where two
discoveries have already been made. VNG's involvement in Agat is a
significant step forward in our strategy to strengthen our base in Norway and
will help us accelerate the exploration and development of a region that has
the capability to dramatically increase our reserve base."

In exchange for the working interests, VNG will assume certain carry
provisions for exploration costs. The agreement is subject to approval by
governmental authorities.

Last month, Endeavour announced that it would assume operatorship of
PL270 from RWE Dea Norge AS and increase its working interest in the license.
In exchange, Endeavour would transfer a portion of its interest in PL426 of
which it was already operator to RWE Dea Norge AS. That agreement was
approved by governmental authorities and will become effective 
August 31, 2007.

Following the completion of both transactions, Endeavour will be majority
owner of both blocks with a 65 percent working interest. VNG Norge AS will
hold a 20 percent working interest and RWE Dea Norge AS will own 15 percent
working interest.

Endeavour estimates that PL 270 and PL 426 contain gross unrisked
resources in excess of 1.6 trillion cubic feet of gas equivalent, including
the Agat discoveries and other identified prospects and leads. The two blocks
cover more than 100,000 acres in a prolific oil and gas trend north of the
Gjoa Field and other nearby undeveloped gas resources.
