Based upon the foregoing and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that the Shares have been duly authorized and, when issued by the Company in accordance with the terms and in the manner set forth in the Plan, will be validly issued, fully paid and non-assessable. The opinion expressed herein is based upon and limited to the General Corporation Law of the State of Delaware, including the statutory provisions, the applicable provisions of the Delaware Constitution and reported judicial decisions interpreting the foregoing.
