Based on that examination and review, I advise you that in my opinion: (i) the Corporation has been duly incorporated and is validly existing under the laws of the State of Maryland; and (ii) to the extent that the operation of the Plan results in the issuance of Common Stock, such shares of Common Stock have been duly and validly authorized and, when issued in accordance with the terms set forth in the Plan, will be legally issued, fully paid and non-assessable. I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to my opinion in the Registration Statement. In giving my consent, I do not admit that I am in the category of persons whose consent is required under Section 7 of the Securities Act of 1933 nor the rules and regulations of the Securities and Exchange Commission thereunder.
