Shell Canada Gets Go Ahead to Purchase Duvernay's Shares

Shell Canada Limited, a wholly owned subsidiary of Royal Dutch Shell plc, has received the approval of the Minister of Industry under the Investment Canada Act for its offer to purchase all of the outstanding common shares of Duvernay Oil Corp. (including common shares issuable upon the exercise or surrender of any options). In approving the acquisition, the Minister determined that the transaction is likely to be of "net benefit to Canada" for purposes of the Investment Canada Act.

Shell Canada also announced that the Commissioner of Competition under the Competition Act (Canada) has granted Shell Canada an advance ruling certificate, which constitutes compliance with the requirements under the Competition Act (Canada). As a result, Shell Canada has now received all necessary Canadian regulatory approvals to proceed with the acquisition of Duvernay.

Shareholders are encouraged to tender their Duvernay common shares to the offer as soon as possible. The offer remains open until 1:01 a.m. (Calgary time) on August 22, 2008, unless the offer is withdrawn or extended by Shell Canada. Under the terms of the offer, Duvernay shareholders will receive C$83.00 for each Duvernay common share.

Shell Canada first announced its intention to make the offer on July 14, 2008 and its wholly owned subsidiary, BRS Gas Corp., mailed its take-over bid circular to the shareholders of Duvernay on July 17, 2008.
