For purposes of this opinion letter, we have examined copies of such agreements, instruments and documents as we have deemed an appropriate basis on which to render the opinions hereinafter expressed.   In our examination of the aforesaid documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all documents submitted to us, the authenticity of all original documents, and the conformity to authentic original documents of all documents submitted to us as copies (including telecopies).  As to all matters of fact, we have relied on the representations and statements of fact made in the documents so reviewed, and we have not independently established the facts so relied on.  This opinion letter is given, and all statements herein are made, in the context of the foregoing.

For the purposes of this opinion letter, we have assumed that (i) U.S. Bank National Association, as Trustee under the Indenture, to be supplemented by the Supplemental Indenture, has and, upon execution of the Supplemental Indenture,  will have all requisite power and authority under all applicable laws, regulations and governing documents to execute, deliver and perform its obligations

We also have assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

This opinion letter is based as to matters of law solely on the applicable provisions of the following, as currently in effect: (i) the Delaware Revised Uniform Limited Partnership Act; and (ii) the laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level). We express no opinion herein as to any other laws, statutes, ordinances, rules or regulations (and in particular, we express no opinion as to any effect that such other laws, statutes, ordinances, rules or regulations may have on the opinion expressed herein). As used herein, the term “Delaware Revised Uniform Limited Partnership Act” includes the statutory provisions contained therein, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Notes have been duly authorized on behalf of the Company and that, following (i) receipt by the Company of the consideration therefor specified in (x) the resolutions of the Board of Trustees of the Company adopted by unanimous written consent dated as of September 14, 2016, (y) the resolutions of the Pricing Committee of the Board of Trustees of the Company adopted on September 15, 2016 and (z) the Underwriting Agreement dated September 15, 2016, by and among the Company and U.S. Bancorp Investments, Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several underwriters named therein, and (ii) the due execution, authentication, issuance and delivery of the Notes pursuant to the terms of the Indenture and, upon its execution, the Supplemental Indenture, and as contemplated by the Prospectus Supplement, the Notes will constitute valid and binding obligations of the Company.

The opinion expressed above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and preferential transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the Notes are considered in a proceeding in equity or at law).

In giving this consent, we do not thereby admit that we are an “expert” within the meaning of the Act.
