This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the prospectus contained therein or the prospectus supplement related thereto, other than as expressly stated herein with respect to the issue of the Shares.
