Endeavour Announces 1-for-7 Share Consolidation

HOUSTON, November 2, 2010 - Endeavour International Corporation (NYSE Amex: END) (LSE: ENDV) today
announces that its Board of Directors have approved a one-for-seven share
consolidation of its common stock, in the form of a reverse stock split, that
is expected to be effective at the opening of trading on November 18, 2010.

As a result of the share consolidation, every seven shares of common
stock outstanding will automatically be combined into one share of common
stock. Holders who would otherwise receive fractional shares will have their
shares rounded up to the next whole share. Each shareholder will continue to
hold the same percentage of the company's outstanding common shares
immediately following the share consolidation as prior to it, except for
minor adjustments due to the rounding up of fractional shares resulting from
the share consolidation.

William L. Transier, chairman, chief executive officer and president,
said, "Endeavour continues to make progress on our growth plans and attract
more attention in the marketplace. With this share consolidation, we expect
to make our stock available to a broader range of investors and position the
company's trading metrics more in-line with its peers. We have consistently
had requests by institutions, with an interest in investing in Endeavour, to
take this action. In addition, having fewer shares outstanding will reduce
the fees associated with various share-based services for our investors, as
well as the company."

Shareholders with questions regarding the share consolidation can refer
to the Question & Answer document found in the Investor Relations section of
the Company's website at www.endeavourcorp.com or speak with their
personal broker.
