Leading Proxy Advisory Firm ISS Recommends That Endeavour Stockholders Elect All of Endeavour's Director Nominees

HOUSTON, May 16, 2014 /PRNewswire/ -- Endeavour International Corporation (NYSE: END) (LSE: ENDV) today announced that Institutional Shareholder Services ("ISS"), the nation's leading proxy advisory firm, has recommended that Endeavour stockholders vote "FOR" all three of Endeavour's highly-qualified and experienced director nominees on the WHITE proxy card at the Company's 2014 Annual Meeting of Stockholders to be held on May 22, 2014.

In its May 15, 2014 report, ISS stated¹:

"Though the company's underperformance is concerning, the dissident has not made a compelling case that further change to the composition of the board is necessary at this time. As such, shareholder support for the management slate of nominees is warranted."

"Poor performance alone, after all, is not itself a compelling case that change is needed on a board.  In this case the board appears to have taken a number of steps to address its underperformance."

Commenting on the ISS report, Endeavour issued the following statement:

We are pleased that ISS supports the election of ALL of Endeavour's highly qualified and experienced director nominees and concluded that no change to Endeavour's Board of Directors is warranted.    

ISS' recommendation reinforces our belief that Endeavour has the right Board, the right strategy and right team in place to drive growth and value creation for all stockholders in this challenging phase for the Company. We strongly urge all Endeavour stockholders to follow the recommendation of ISS and vote "FOR" our director nominees on the WHITE proxy card today.

Endeavour stockholders are reminded that their vote is extremely important, and that they have an opportunity to protect their investment in Endeavour by voting FOR Endeavour's three director nominees using the WHITE proxy card today.
