On the basis of the foregoing, we are of the opinion that the Shares covered by the Plan have been duly authorized and, when and to the extent issued in accordance with the terms of the Plan, will be legally and validly issued, fully paid and non-assessable.

We are members of the Bar of the State of New York and the foregoing opinion is limited to the laws of the State of New York and the General Corporation Law of the State of Delaware.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.
