Tullow Oil plc - Board Change

28 April 2008 - The Board of Tullow Oil plc (Tullow) announces with regret that
Tom Hickey has today given notice of his resignation from the Board and from the
position of Chief Financial Officer of Tullow. 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. '
