Selected Reserve Report Highlights

The NSAI Report was prepared for the Corporation at the direction of Addax Petroleum's Technical and Reserves Committee, using assumptions and methodology guidelines outlined in the Canadian Oil and Gas Evaluation Handbook and in accordance with National Instrument 51-101.

The NSAI Report is limited to oil reserves on the Corporation's properties and does not include exploration and contingent resources. Highlights of the NSAI Report and the Corporation's 2006 production, with comparatives to 2005 results, where appropriate, are as follows:

- Total gross working interest proved plus probable reserves increased by approximately 80 per cent to 353.7 MMbbl as at December 31, 2006 from 196.7 MMbbl as at December 31, 2005. - In Nigeria, gross working interest proved plus probable reserves increased by approximately 10 per cent to 215.4 MMbbl as at December 31, 2006 from 196.7 MMbbl as at December 31, 2005 and oil production for 2006 averaged 86,300 bbl/d. - In Gabon, gross working interest proved plus probable reserves are estimated to be 98.2 MMbbl as at December 31, 2006. The Corporation acquired the business of Pan-Ocean Energy Corporation Limited ("Pan- Ocean") in Gabon in September 2006 which had reported gross working interest proved plus probable reserves of 67.5 MMbbl as at December 31, 2005 as estimated by Pan-Ocean's independent reserve engineers. Since Addax Petroleum acquired the assets in Gabon in September, the Corporation has achieved averaged daily production of 11,800 bbl/d and 3,750 bbl/d over the entire year. - In the Kurdistan Region of Iraq, gross working interest proved plus probable reserves for the Corporation at the Taq Taq field are estimated to be 40.1 MMbbl as at December 31, 2006. The Corporation did not book any reserves for the Taq Taq field in 2005. - The Corporation's overall 2006 reserves replacement ratio was 5.8. The reserves replacement ratio is calculated by dividing the gross working interest proved plus probable reserve additions of 189.9 MMbbl (including acquisitions and before deduction of 2006 production of 32.9 MMbbl) by the 2006 production. - The Corporation's 2006 reserve life index, based on proved plus probable reserves as at December 31, 2006 and average 2006 oil production, has increased by 2.5 years to 10.8 years in 2006 from 8.3 in 2005. The 2006 reserve life index is calculated by dividing the gross working interest proved plus probable reserves of 353.7 MMbbl as at December 31, 2006 by the 2006 production of 32.9 MMbbl. - Total gross working interest proved plus probable plus possible reserves have increased by 72 per cent to 480.4 MMbbl as at December 31, 2006 from 278.7 MMbbl as at December 31, 2005. The estimated net present value of future net revenue after taxes for the gross working interest proved plus probable plus possible reserves as at December 31, 2006, discounted at 10 percent, is $4,147 billion based on forecast prices and costs.
