You have requested our opinion as to the matters set forth below in connection with the Registration Statement. For the purpose of rendering such opinion, we have made such factual and legal examinations as we deemed necessary under the circumstances, and in that connection we have examined, among other things, originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials, certificates of officers or other representatives of the Company, and other instruments and have made such inquiries as we have deemed appropriate for the purpose of rendering such opinion.

In our examination, we have assumed without independent verification (i) the legal capacity and competency of all natural persons, (ii) the genuineness of all signatures, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as conformed or photostatic copies and the authenticity of the originals of such latter documents.
