Tullow Oil plc - Board Change

Tom's decision to leave Tullow reflects the considerable personal demands of his role in a London-based multi-national company and his desire to live full time in Ireland. Tom believes that it would not be possible for him to continue to fulfill the demands of his role from Dublin as Tullow continues its rapid growth.

The Board will immediately begin the process of recruiting his successor and Tom will remain in his role until a suitable candidate has been identified to ensure an orderly transition. It is currently envisaged that he will leave sometime after the Interim Results in August and before the end of the year.

Commenting today, Aidan Heavey, Chief Executive of Tullow said:

"I am personally very sad that Tom is to leave Tullow as he has made an outstanding contribution to the Group since he joined us in 2000. His commitment has been exceptional and we are all truly disappointed that he will not be part of the next phase of growth and development of the business. We fully understand his decision and wish him every happiness and success in the future."

Tom Hickey added:

"It has been a great pleasure to work with Aidan and the team at Tullow for the last eight years. During this period Tullow has consistently demonstrated strong business growth and delivered exceptional shareholder returns and I believe the team we have built will continue this performance. My decision to move on from Tullow has been a very difficult one, but I believe it is the best personal long-term course of action."
