In all such examinations we have assumed conformity with the original documents of all documents submitted to us as conformed or photostatic copies, the authenticity of all documents submitted to us as originals and the genuineness of all signatures on all documents submitted to us. On the basis of the foregoing, we are of the opinion that the issuance and sale of the Shares upon exercise of the Rights have been duly authorized and when (i) the Registration Statement becomes effective under the Securities Act of 1933, as amended, (ii) the holders of the Rights have complied with the terms of the Rights in connection with the exercise thereof, (iii) certificates representing the Shares have been manually signed by an authorized officer of the transfer agent and registrar for the Common Stock and registered by such transfer agent and registrar, and (iv) the Shares have been delivered to and paid for as contemplated by the Rights and the Registration Statement, the Shares will be validly issued, fully paid and non-assessable. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference made to our firm under the caption "Legal Matters" in the prospectus constituting part of the Registration Statement.
