Endeavour International Corp.

Endeavour International Corp., Houston, (NYSE Amex: END; London: ENDV.l) has retained Jefferies International Ltd. and Lambert Energy Advisory Ltd. to review strategic alternatives for its North Sea assets to include joint-venture opportunities or asset sales.

Endeavour chief executive and president William L. Transier says, "We have believed for some time that the discount in our stock price was related to the length of time between discovery and production and the relatively high development costs in the U.K. Our entry into the U.S. onshore arena balances this position with an inventory of properties that can be developed in a much shorter time period and at lower cost."

Endeavour currently owns interests in four producing fields in the U.K. North Sea with four developments underway.

Production from U.K. assets average 3,651 barrels of oil equivalent per day in 2009. Four development projects are underway with proved plus probable reserves of 38.9 million barrels of oil equivalent, primarily gas. Endeavor holds a 55.6% operated interest in Rochelle, and 12.5% in Cygnus, 25% in Columbus, and 10% in Bacchus.

The company plans to focus on U.S.-based assets.
