     As counsel to the Company in connection with the proposed issuance and sale of the Securities, we have examined or are otherwise familiar with (i) the Restated Articles of Incorporation of the Company; (ii) the By-Laws of the Company, as amended to date; (iii) the Registration Statement, including the Prospectus and exhibits thereto (including those incorporated by reference); (iv) the Indenture and the Officers’ Certificate; and (v) such other documents, records and instruments as we have deemed necessary or appropriate to enable us to render this opinion.

     In our examination of the above-referenced documents, we have assumed the genuineness of all signatures, the authenticity of all documents, certificates and instruments submitted to us as originals and the conformity with the originals of all documents submitted to us as copies.

     Based upon and subject to the foregoing, assuming that the Indenture has been duly authorized, executed and delivered by, and represents the valid and binding obligation of, the

Trustee, and having regard for such legal considerations as we deem relevant, we are of the opinion that the Securities, when executed, authenticated and issued in accordance with the Indenture and in the manner and for the consideration contemplated by the Registration Statement and the Prospectus, will be legally issued and valid and binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles (regardless of whether enforcement is considered in a proceeding in equity or at law).

In giving such consent, we do not admit that we are “experts” within the meaning of Section 11 of the Securities Act or within the category of persons whose consent is required by Section 7 of the Securities Act.
