Pachamama Board Approval and Fairness Opinion

The approval of Pachamama shareholders will be required as a condition to completing the Merger. Shareholders will be asked to approve the Merger at a meeting (the “Meeting“) to be held on or about April 30, 2012. Based on a number of factors, including receipt of a verbal fairness opinion from Raymond James Ltd. that the Merger is fair, from a financial point of view, to Pachamama shareholders, the Board of Directors determined that the Merger was in the best interests of Pachamama and recommends that Pachamama shareholders vote in favour of approving the Merger at the Meeting.
