The Shares have been or may be issued by the Company pursuant to the Company's Employee Stock Purchase Plan or the Company's Stock Compensation Plan(collectively, the "Plans"), which provides for the possible issuance of shares of Common Stock of the Company in accordance with the respective Plans.

Based upon the foregoing, we are of the opinion that the Shares have been duly authorized and, when issued as contemplated by the Registration Statement, will be legally issued, fully paid and non-assessable shares of capital stock of the Company. We hereby consent to be named in the Registration Statement and in the Prospectus constituting a part thereof, as amended from time to time, as the attorneys who will pass upon legal matters in connection with the issuance of the Shares, and to the filing of this opinion as an exhibit to the aforesaid Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933 or the rules of the Securities and Exchange Commission. Very truly yours, DAVIS, GRAHAM & STUBBS LLP 7
