Mr. Thorne will thereupon continue to serve as Chairman of the Board.

Carl F. Thorne, Chairman and Chief Executive Officer, commented "We are very pleased that Dan Rabun is joining ENSCO. His ability and diverse experience will add additional depth and breadth to our executive management team. Because he has been our primary outside counsel for many years, and previously served on our Board, Dan is intimately familiar with our operations and business philosophy. He embraces our core fundamental values of discipline, business integrity and ethics. This demonstrated compatibility, together with his legal and financial experience and strong leadership and management skills, make Dan an outstanding addition to ENSCO's management team and its Board.

"We also commend Bill Chadwick upon his promotion to Executive Vice President and Chief Operating Officer. Bill has been an integral part of ENSCO's management team since the Company's inception. His wealth of experience, demonstrated leadership capabilities, and participation in the formulation of our core values have made a significant contribution to ENSCO's growth and success over the years, and will continue to serve Bill well as he assumes his new responsibilities.

"The election of Mr. Rabun to our management team and the promotion of Mr. Chadwick to his new role are the result of our ongoing commitment to succession planning. The said commitment and its positive results will continue to provide for, and allow, orderly and timely transition so as to perpetuate the Company's historical success."
