We are solicitors qualified to practice law in the Province of Nova Scotia and we express no opinion as to any laws or any matters governed by any laws other than the laws of the Province of Nova Scotia and the federal laws of Canada applicable therein. As to various questions of fact material to our opinion, which we have not verified independently, we have relied upon documents or certificates of governmental authorities and the Company or its officers. In expressing the opinion in paragraph (a) with respect to the valid existence of the Company, we have relied exclusively on a Certificate of Status issued under the Companies Act (Nova Scotia) dated on April 26, 2002, a copy of which has been provided to you. On the basis of the foregoing we are of the opinion that: (a) The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation (b) The Notes have been duly authorized by the Company.
