Upon the basis of such examination, we advise you that in our opinion the Shares have been duly authorized and reserved for issuance, and, when issued upon conversion or in payment of dividends or exercise of the Securities, as applicable, in accordance with the terms thereof, will be legally issued, fully paid and nonassessable.

Our opinion is limited to the General Corporation Law of the State of Delaware and the United Stated federal laws, and we disclaim any opinion whatsoever with respect to matters governed by the laws of any other jurisdiction.

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to this firm under the caption “Legal Matters” in the Prospectus which is a part of the Registration Statement. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
