Commenting today, Aidan Heavey, Chief Executive, said:

“We have had our best ever year in 2008 with phenomenal exploration and appraisal results in Ghana and Uganda, significantly increasing the Group’s booked Reserves and Resources estimates. The Jubilee development in Ghana is progressing very well and is on track for first oil in the second half of 2010. Another major milestone was recently achieved in Uganda as we comfortably exceeded the commercial threshold with further world class discoveries.

We have made a strong start in 2009 and looking ahead, Tullow has excellent opportunities to continue to grow its business and high grade the portfolio, with our main focus on Ghana and Uganda. Our success, and strong support from our shareholders and banks, means that the equity placement announced today and the imminent closure of our debt refinancing will secure funding and give Tullow very significant financial and operational strength for the next phase of transformational growth.”
