As counsel for the Company, we have made such legal and factual examinations and inquiries as we deemed advisable for the purpose of rendering this opinion. In addition, we have examined such documents and materials, including the Company's Certificate of Incorporation, Bylaws, the Plan and other corporate records of the Company, as we have deemed necessary for the purpose of this opinion.
