Proceeding with Formal Business Combination

December 9, 2009 - Vancouver, British Columbia – Altima Resources Ltd. ("Altima") and Unbridled Energy Corporation ("Unbridled") (Altima and Unbridled are collectively referred to as the "Companies") announce that, in connection with their ongoing transaction preparations, they have executed a formal Business Combination Agreement that supersedes the letter agreement first announced in their joint new release of August 31, 2009.  The Business Combination Agreement sets out in greater detail the formal terms and conditions for the acquisition of Unbridled by Altima through a one-for-one shares exchange (the “Transaction”).

The parties are well into the process of preparing a formal information circular describing the Transaction that that parties expect will be delivered to Unbridled shareholders in the latter half of December 2009.  Unbridled expects to hold a special meeting of its shareholders in January 2010 at which time it will seek shareholder approval of the Transaction. The approval of Altima shareholders is not expected to be required in order to complete the Transaction.

The Transaction remains subject to a number of conditions, including the finalization of formal documentation, receipt by each of Altima’s and Unbridled’s Board of Directors of an independent fairness opinion regarding the transaction, receipt of Court approval, regulatory approval (including the acceptance of the TSX Venture Exchange), and the approval of the shareholders of Unbridled of the Transaction, and other customary conditions.

Further information regarding the Transaction will be included in subsequent shareholder material, including a detailed proxy circular. Unbridled and Altima will keep their shareholders updated on the progress of the Transaction as developments warrant.
