In that regard, we are generally familiar with the proceedings taken or to be taken in connection with the proposed authorization, issuance and sale of any series of Notes and have examined and relied upon copies of such statutes, documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including the Registration Statement, the Amended and Restated Indenture, the form of Indenture Supplement (including the form of Notes included as an exhibit thereto) and the form of Underwriting Agreement filed as an exhibit to the Registration Statement.

Based on and subject to the foregoing, we are of the opinion that, with respect to the Notes, when (a) the related Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, (b) such Notes have been duly executed and issued by the Issuing Entity, authenticated by the Indenture Trustee and sold by the Issuing Entity and (c) payment of the agreed consideration for such Notes shall have been received by the Issuing Entity, all in accordance with the terms and conditions of the related Indenture and the related Underwriting Agreement and in the manner described in the Registration Statement, such Notes will have been duly authorized by all necessary action of the Issuing Entity and will be legally issued and binding obligations of the Issuing Entity and entitled to the benefits afforded by the related Indenture, except as may be limited by bankruptcy, insolvency, reorganization, arrangement, moratorium or other similar laws relating to or affecting creditors’ rights generally (including, without limitation, fraudulent conveyance laws), and by general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether enforceability is considered in a proceeding in equity or at law.

Our opinions expressed herein are limited to the federal laws of the United States, the laws of the State of New York, the Delaware General Corporation Law and the Delaware Statutory Trust Act. We express no opinion herein as to the laws of any other jurisdiction and no opinion regarding the statutes, administrative decisions, rules, regulations or requirements of any county, municipality, subdivision or local authority of any jurisdiction.
