Based upon and subject to the foregoing and upon our review of such matters of law as we have deemed necessary and appropriate to render our opinion as expressed herein, and subject to the assumptions, exceptions, limitations and qualifications set forth herein, it is our opinion that the shares of Series BB Preferred Stock to be issued pursuant to the Deposit Agreement and the Committee Resolutions have been duly authorized for issuance by the Company and, when issued, delivered and paid for in accordance with the Deposit Agreement and the Committee Resolutions, will be validly issued, fully paid and non-assessable under the General Corporation Law.
