Having examined all instruments, documents and records which I deemed relevant and necessary for the basis of my opinion hereinafter expressed, I am of the opinion that the shares of Common Stock which may be issued under the Plans are duly authorized and, when issued against receipt of the consideration therefore in accordance with the provisions of the Plans and the appropriate agreements thereunder, will be validly issued, fully paid and nonassessable.

I hereby consent to the filing of this opinion as an exhibit to the Registration Statement referred to above and the use of my name wherever it appears in said Registration Statement. In giving this consent, I do not admit that I am within the category of persons whose consent is required under Section 7 of the Securities Act, the rules and regulations of the Securities and Exchange Commission promulgated thereunder or Item 509 of Regulation S-K.
