do we really want Palo Alto on the BOD?

CALGARY, ALBERTA--(Marketwire - Aug. 11, 2009) - Canadian Superior Energy Inc. ("Canadian Superior" or the "Company") (TSX:SNG)(NYSE Amex:SNG) announced today that it is finalizing its information circular for forwarding to shareholders in connection with its annual and special meeting of shareholders. The meeting, which had previously been scheduled for September 1, 2009, will now be held on September 9, 2009.

The board of directors of Canadian Superior will be substantially reconstituted at the meeting. The nominees for the board named in the information circular are Kerry R. Brittain, Marvin M. Chronister, Dr. James Funk, Dr. William Roach, Gregory G. Turnbull and Richard Watkins, of whom the first four were proposed by Palo Alto Investors, LLC ("Palo Alto") in the settlement agreement referred to below. All the nominees to the board are independent, as that term is defined in applicable Canadian securities legislation. These nominees have the support of Palo Alto which previously had requisitioned a meeting of shareholders of Canadian Superior to, among other things, elect a replacement board of directors. Canadian Superior has entered into a settlement agreement with Palo Alto which, subject to the approval of the Court of Queen's Bench of Alberta, provides for Canadian Superior to nominate and support the election of the individuals named above as directors of Canadian Superior. The Company has filed an application with the Court requesting the Court's approval of the terms of the settlement agreement. Hardie and Kelly Inc., the Court-appointed Monitor under the CCAA proceedings, has advised the Company that it will recommend approval of the settlement agreement to the Court.

At the meeting, shareholders will also be asked to approve the previously announced proposed plan of arrangement involving Canadian Superior, Challenger Energy Corp. and the shareholders of Challenger Energy Corp.

The Company expects to mail its information circular and form of proxy to shareholders on or about August 14, 2009. Shareholders are urged to review the materials, and to return their duly completed form of proxy (voting in favour of each of the items set out in the Notice of Meeting) as soon as possible and in any event prior to September 4, 2009.
