Terms defined in the Agreement and used but not defined herein have the meanings given to them in the Agreement. We have acted as Canadian counsel to the Credit Support Provider in connection with the execution and delivery of the Credit Support Document. We have examined the Agreement, the Credit Support Document, the Credit Support Provider's constating documents and such other documents as we have deemed necessary or appropriate for purposes of the opinions expressed herein. We have also made such investigations and considered such questions of law as we have considered necessary for the purpose of rendering this opinion. In such examination we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies, certified or otherwise. We express no opinion with respect to the laws of any jurisdiction other than the laws of the Province of Ontario and the laws of Canada applicable therein. Based on the foregoing we are of the opinion that: 1. The Credit Support Provider has been duly organized incorporated and is validly existing and in good standing under the laws of the Province of Ontario. 2. The execution and delivery of the Credit Support Document and the performance by the Credit Support Provider of its obligations thereunder have been duly authorized by the Credit Support Provider, are within the corporate power of the Credit Support Provider and do not conflict with, or result in a breach of, (i) the constating documents of the Credit Support Provider, or (iii) any agreement, decree, order, judgment, injunction or other instrument binding on or affecting the Credit Support Provider. 3. The Credit Support Document has been duly authorized, executed and delivered by the Credit Support Provider to the Bank. 6. The Credit Support Document constitutes a legal, valid and binding obligation of the Credit Support Provider enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, and other similar laws and equitable principles of general application affecting the rights of 35 creditors, or limiting the availability of specific performance, injunctive relief or any other equitable remedy. This opinion is provided solely for your benefit and is not to be relied upon for any purpose other than in respect of the Agreement or by any other person. Yours very truly, 36
