- Addax Petroleum Total Production Exceeds 140,000 Barrels Per Day for
First Time

Addax Petroleum Corporation ("Addax Petroleum" or the "Corporation")
(TSX: AXC, LSE: AXC) is pleased to announce that one year after the 
acquisition of the operations of Pan Ocean Energy Corporation Limited 
("Pan Ocean"), it has increased production more than three-fold to in 
excess of 30,000 barrels per day. In addition to this strong production 
growth, the Corporation announced in January 2007 a 45 per cent increase 
in its gross working interest proved plus probable reserves as at 
December 31, 2006. This substantial growth has been achieved primarily by 
increasing organisational capabilities, operating an intensive drilling 
campaign and constructing related production and export facilities.

Commenting, Jean Claude Gandur, President and Chief Executive Officer of
Addax Petroleum said: "We are extremely pleased with the results of our first
year of operations in Gabon during which we have significantly increased
production, booked a large increase in reserves and have become an integral
operator in the country. We were confident that our additional investment and
results based approach would facilitate this growth and are pleased to
demonstrate our achievements to shareholders. Our property portfolio in Gabon
has been a large contributor to achieving daily production in excess of
140,000 barrels per day, continues to be a good complement to our operations
in Nigeria and has become a vital component of Addax Petroleum's future."

Background

Addax Petroleum completed the acquisition of the exploration and
production assets of Pan Ocean in September 2006. The assets acquired consist
primarily of the operated, onshore Maghena, Panthere NZE and Remboue license
areas containing the producing Tsiengui, Obangue and Remboue oil fields and
the Autour oil discovery. The assets acquired also included the non-operated
onshore Awoun license area containing the Koula oil field development and the
Damier oil discovery, and the non-operated offshore Etame Marin license area
which contains the Etame, South Tchibala/Avouma and the Ebouri oil fields.
During the first year of ownership Addax Petroleum has, on its operated
onshore properties, focussed primarily on the production and reserves
development in addition to preparing for future exploration and, on both the
non-operated onshore and offshore properties, has been proactive with its
partners to encourage increased development and exploration activity.
Accordingly, through activity and investment since acquisition, Addax
Petroleum has grown significantly its business in Gabon in terms of
production, reserves, exploration potential and organisational capability.

Production and Development

Since the acquisition of Pan Ocean in early September, 2006, gross oil
production from Addax Petroleum's Gabon assets, tabulated below, has grown
steadily from an average of 9.2 Mbbl/d to 26.5 Mbbl/d. Presently, oil
production is approximately 30 Mbbl/d barrels per day. Much of the production
increase has occurred in the past month as the Corporation has overcome and
corrected a number of minor operational issues onshore which had otherwise
constrained production.

Year-over-year production increases have been driven by a high level of
development activity on the main Addax Petroleum operated onshore producing
Tsiengui and Obangue fields including bringing 14 new wells on production,
adding a second dedicated drilling rig, expansion of related production and
export facilities including the commissioning of a new 30-kilometre, 10-inch
export pipeline. The development of the Tsiengui and Obangue fields will
continue into 2008. There is also increased development activity on the
Corporation's non-operated properties, where the development has commenced
for the onshore Koula field in Awoun and the offshore Ebouri field in Etame
Marin. As Addax Petroleum expects to continue growing production from onshore
Gabon beyond its current export capacity, the Corporation has commenced the
extension of its export system, including a new 38-kilometre, 12-inch
pipeline which will allow for further increases in production by availing of
spare capacity through the Shell operated Rabi station. The Corporation
expects the expanded export system to be commissioned in the second half of
2008.

Addax Petroleum expects its Gabon production to average approximately
30 Mbbl/d for the remainder of 2007, subject to sufficient pipeline capacity
from another operator, and in combination with the Corporation's Nigeria
operations, overall production is expected to average in excess of 140 Mbbl/d
for the remainder of 2007. Addax Petroleum surpassed the 140 Mbbl/d
production level for the first time in the Corporation's history in early
September 2007.

In Gabon, and as previously announced by Addax Petroleum on January 18,
2007, Addax Petroleum's gross working interest proved plus probable reserves
were estimated by the Corporation's independent reservoir engineers,
Netherland, Sewell and Associates, to be 98.2 MMbbl as at December 31, 2006.
This represented an increase of 45 per cent over the reported gross working
interest proved plus probable reserves of 67.5 MMbbl as at December 31, 2005
as estimated by the previous operator's independent reserve engineers.

Exploration and Appraisal

Whereas production development and growth has been the primary focus in
this first year, the Corporation has been active to progress the exploration
potential of its Gabon licenses, particularly onshore. The Corporation has
commenced a 164 km(2), 3D seismic acquisition campaign on the onshore Maghena
and Awoun license areas and on the Panthere NZE license area, drilled a
successful appraisal well at the Autour field and plans to appraise further
in 2008. The Corporation's onshore operated exploration position was further
increased through the acquisition, subject to government consent, of a 50 per
cent interest in the Epaemeno license area, immediately north of the
Corporation's Maghena and Awoun license areas.
