Canadian Superior Reiterates Recommendation that Canada Southern Shareholders Should Accept Canadian Superior's Amended and Revised Offer

CALGARY, ALBERTA--(CCNMatthews - July 31, 2006) - Canadian Superior Energy Inc. ("Canadian Superior") (TSX:SNG) (AMEX:SNG) of Calgary, Alberta, Canada further reiterated today that shareholders of Canada Southern Petroleum Ltd. ("Canada Southern") (NASDAQ:CSPLF) (TSX:CSW) should accept the amended and revised offer from Canadian Superior. On July 26, 2006, Canadian Superior extended its previous offer for Canada Southern and is in the process of amending its bid for Canada Southern. As previously announced, Canadian Superior is amending its offer for Canada Southern with a new bid that is estimated to be worth Cdn $17.10 per share (US $14.97). Under the amended offer, shareholders of Canada Southern will have the right to elect to receive either (i) 2.0 shares of Canadian Superior, Cdn $2.50 cash and a 25% net profit interest, in the form of separately tradable Arctic Royalty Trust Units ("ART's") that will be registered and tradable securities, in up to approximately 927 bcfe of natural gas, being the estimated net amount of natural gas Canada Southern attributes to its interest in the Canadian Arctic Islands (the "amended consideration"), or (ii) Cdn $2.50 cash and 2.75 common shares of Canadian Superior for each Canada Southern share, being the consideration offered under Canadian Superior's original offer for Canada Southern. Canadian Superior estimates the value of the net profit interest portion of the amended consideration to be approximately Cdn $10.00 per Canada Southern share based on a value of approximately Cdn $0.65 per MCF of natural gas in place. In the Western Canada sedimentary basin, natural gas is being sold for over Cdn $2.00 per MCF of natural gas in place. Canadian Superior's offer of the amended consideration is conditional on Canadian Superior's success in acquiring at least 66 2/3% of the outstanding shares of Canada Southern.

Oil and gas exploration and development is a high risk speculative business and there can be no assurance to investors that drilling will be productive or that shareholders who elect to receive the amended consideration will realize any royalties on the net profit interest portion of the amended consideration. There are currently no announced plans to develop Canada Southern's Arctic Islands natural gas resources, and future operations, if any, in the Arctic Islands may be curtailed, delayed or cancelled as a result of numerous factors, including mineral lease title deficiencies, equipment failures, weather conditions, shortages or delays in sourcing qualified personnel, shortages or delays in the delivery of equipment, ability to access surface topography, compliance with governmental requirements or other factors. The future commercial success of oil and natural gas exploration, development and production activities is subject to certain risks, including risks set out in Canadian Superior's annual information form, which was filed with applicable Canadian provincial securities regulatory authorities and the United States Securities and Exchange Commission (the "SEC").

Canadian Oil Sands Limited ("Canadian Oil Sands") (TSX:COS.UN) is currently offering Canada Southern shareholders US $13.10 (approximately Cdn $14.81) and their bid expires at 8:00 a.m. (MST) on August 1, 2006, as compared to Canadian Superior's amended offer estimated to be worth Cdn $17.10 per share (US $14.97). If Canadian Oil Sands is successful in acquiring 66 2/3% of the outstanding shares of Canada Southern, Canadian Superior will have the right to withdraw or terminate its offer of the amended consideration.
