In rendering this opinion, we have assumed, without independent investigation or verification, that: (i) each natural person signing any document reviewed by us had the legal capacity to do so; (ii) each person signing in a representative capacity (other than on behalf of the Company) had the authority to sign in such capacity; (iii) the Agreement has been duly authorized and validly executed and delivered by the parties thereto other than the Company; (iv) at or prior to the time of delivery of the Global Notes, the authorization of the Notes and of each series of notes of which the Notes are a part, including the Series Terms Certificates, will not have been modified or rescinded and there will not have occurred any change in law affecting the validity or enforceability of the Notes; (v) the Global Notes executed and delivered by the Company as contemplated herein will be identical in form to the forms of the Global Notes examined by us as described herein; and (vi) (A) the Indenture is and, at the time of delivery of the Notes, will be the legal, valid and binding agreement of the Trustee, enforceable against the Trustee in accordance with its terms, (B) at the time of delivery of the Notes, the Indenture will continue to be the legal, valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, and (C) the Indenture has been and will continue to be at all pertinent times qualified pursuant to the Trust Indenture Act of 1939, as amended.

As to certain facts material to our opinion, we have made no independent investigation or verification of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials, the Company and officers or other representatives of the Company and the representations of the Company in the Agreement.

Based on the foregoing and subject to the qualifications set forth below, we are of the opinion that, upon the execution of the Global Notes, the authentication of the Global Notes in accordance with the terms of the Indenture and the delivery of the Global Notes against payment therefor in accordance with the Agreement, the Notes will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, and will be entitled to the benefits of the Indenture.

The foregoing opinions are qualified to the extent that the enforceability of the Indenture, the Notes or any related document or instrument may be limited by or subject to the effects of bankruptcy, insolvency, moratorium, reorganization, liquidation, rearrangement, probate, conservatorship, fraudulent conveyance, fraudulent transfer or other similar laws (including court decisions) now or hereafter in effect relating to or affecting creditors’ rights and remedies generally or providing for the relief of debtors, general principles of equity (regardless of whether such remedies are sought in a proceeding in equity or at law) or public policy.

We note that the enforceability of specific provisions of the Indenture and the Notes may be subject to (i) standards of reasonableness and “good faith” limitations and obligations such as those provided in the New York Uniform Commercial Code and similar applicable principles of common law and judicial decisions and (ii) the course of dealings between the parties, the usage of trade and similar provisions of common law and judicial decision.

We express no opinion as to the enforceability of the severability clauses in Section 1.11 of the Original Indenture, Section 5 of the First Supplemental Indenture, Section 5 of the Second Supplemental Indenture, Section 5 of the Third Supplemental Indenture or Section 16 of the Global Notes or any provision of the Indenture or the Global Notes that purports to waive or not give effect to rights to notice, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law, including Section 1.15 and Section 12.01 of the Original Indenture and Section 13 of each of the Global Notes. We express no opinion with respect to the enforceability of (i) the parenthetical clause in Section 8.07(i) of the Original Indenture relating to the limitations on the compensation of trustees or (ii) Section 12.01 of the Original Indenture and Section 13 of each of the Global Notes to the extent that either of those provisions purport to waive liability for violation of securities laws. We express no opinion as to any provision of the Indenture that purports to confer subject matter jurisdiction in respect of bringing suits, enforcement of judgments or otherwise on any federal court, to the extent such court does not otherwise have such jurisdiction.

The foregoing opinions are limited in all respects to matters under and governed by the federal laws of the United States of America, the laws of the State of New York and the General Corporation Law of the State of Delaware, as each is in force and effect as of the date of this opinion. We do not express any opinion as to the laws of any other jurisdiction.

We consent to the filing by you of this opinion as an exhibit to the Company’s Current Report on Form 8-K to be filed with the Commission on the date hereof and the incorporation by reference of this opinion letter into the Registration Statement, and we further consent to the use of our name under the caption “Legal Matters” in the Prospectus Supplement. In giving this consent, we do not admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder. This opinion is expressed as of the date hereof, and we disclaim any undertaking to advise you of any subsequent changes in the facts stated or assumed herein or any subsequent changes in law.
