Endeavour Announces Redemption and Amendment of Convertible Preferred Stock

HOUSTON, November 18 - Endeavour International Corporation (Amex: END) (LSE: ENDV) today
announced that it has signed an agreement to redeem US$75 million of its
US$125 million Series C Convertible Preferred Stock and amend the terms of
the remaining US$50 million outstanding. The redemption and amendment reduces
the current dilution to common shareholders and eliminates the potential
dilution Endeavour common shareholders faced if equity capital was utilized
for value-added growth opportunities.

"We believe the redemption and amendment gives Endeavour additional
simplicity in its capital structure and financial flexibility to create
further avenues for growth by removing the dilution uncertainty for our
common equity," said William L. Transier, chairman and chief executive
officer. "Endeavour has not pursued several potential business opportunities
due to concerns about dilution to our common shareholders. Our convertible
preferred stockholders also recognized the restrictive impact of the
anti-dilution provisions to our growth efforts. The ability to accomplish
this very positive transaction with our convertible holders is a strong
endorsement of our management team and the underlying value of Endeavour."

Endeavour's redemption of US$75 million will include a US$25 million cash
payment and the issuance of a five-year US$50 million subordinated note
payable, pre-payable at anytime, bearing cash interest at an annual rate of
10 percent plus two percent interest accruing in the balance of the note. It
will amortize over a four-year period beginning in 2011. The remaining US$50
million outstanding Series C Convertible Preferred Stock has been amended to
reduce the annual dividend rate to 4.5 percent from 8.5 percent, adjust the
conversion price to US$1.25 per share and eliminate the previously included
anti-dilution provisions.
