Retirement of Executive Director

Tullow Oil plc (Tullow) announces the forthcoming retirement of its UK Business
Unit Managing Director, John Lander. Mr Lander will retire from full-time work
in mid April, however he will continue to perform consulting projects with
Tullow in the future.

Since joining Tullow in 2000, John has been instrumental in the growth of Tullow
Oil UK Ltd, the Tullow subsidiary set up to complete the acquisition of a
significant parcel of BPAmoco/ARCO assets in the Southern North Sea. This proved
to be a transforming deal for Tullow. Since 2001 the Company has focused on
extracting value from the assets and consolidating acreage and infrastructure in
this core area.

John Lander started his career with Shell in the 60's and has over 35 years
experience in the international oil production arena, the latter 20 years as a
director of Pict, Premier and British Borneo. Mr Lander also served as President
of the Petroleum Exploration Society of Great Britain in 1996.

John will be replaced as General Manager in the UK by Paul McDade. Paul joined
Tullow to head up operations & technical matters in June 2001. A petroleum
engineer by discipline, Paul has extensive UKCS and international experience
with LASMO, Talisman and Conoco.

Pat Plunkett, Chairman of Tullow, commented 'I would like to thank John for his
significant contribution over the past years. His wisdom and experience have
enabled us to build a firm base from which to grow in the UKCS, with the capture
of further assets in the area, including vital infrastructure and strategic
operatorships.'
