Based upon, and subject to, the foregoing, we are of the opinion that the Shares are duly authorized and, upon exercise of the Options in accordance with the terms of the Plans against payment of the exercise price therefor (as applicable), will be, assuming no change in the applicable law or pertinent facts, validly issued, fully paid, and non-assessable. We hereby consent to the filing of this opinion as Exhibit 5 to the Registration Statement. In giving the foregoing consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission promulgated thereunder.
