(formerly known as The Bank of New York Trust Company, N.A.), as Trustee (the “Trustee”).  As used in this opinion letter, the term “Prospectus” means the Prospectus Supplement and the Base Prospectus, including the documents incorporated or deemed incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act.

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

Morgan Securities LLC, Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several underwriters named in Schedule I to the Underwriting Agreement, relating to the issuance and sale of the Notes, (vi) (a)

We have also examined and relied upon originals, or copies of originals, certified or otherwise identified to our satisfaction, of such records of the Company and other corporate documents, have examined such questions of law and have satisfied ourselves as to such matters of fact as we have considered relevant and necessary for the opinion set forth herein.  We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all natural persons and the conformity with the original documents of any copies thereof submitted to us for examination.  We also have assumed that the Indenture is the valid and legally binding obligation of the Trustee.

With respect to each instrument or agreement referred to in or otherwise relevant to the opinions set forth herein (each, an “Instrument”), we have assumed, to the extent relevant to the opinions set forth herein, that (i) each party to such Instrument (if not a natural person) was duly organized or formed, as the case may be, and was at all relevant times and is validly existing and in good standing under the laws of its jurisdiction of organization or formation, as the case may be, and had at all relevant times and has full right, power and authority to execute, deliver and perform its obligations under such Instrument, (ii) such Instrument has been duly authorized, executed and delivered by each party thereto and (iii) such Instrument was at all times and is a valid, binding and enforceable agreement or obligation, as the case may be, of each party thereto; except that we make no such assumptions with respect to the Company.

This opinion letter is limited to the laws of the State of New York and the General Corporation Law of the State of Delaware.

Based on the foregoing and subject to the qualifications and limitations set forth herein, we are of the opinion that the Notes constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, fraudulent transfer and other similar laws relating to or affecting creditors’ rights generally and to general equitable principles (regardless of whether considered in a proceeding in equity or at law), including concepts of commercial reasonableness, good faith and fair dealing and the possible unavailability of specific performance and injunctive relief.

We hereby consent to the filing of this opinion letter as an Exhibit to the Company’s Current Report on Form 8-K on the date hereof, which Form 8-K will be incorporated by reference into the Registration Statement, and to all references to our firm included in or made a part of the Prospectus.  In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required by Section 7 of the Securities Act.
