Debt Securities will be issued in accordance with the Indenture, the Registration Statement and the Prospectus. We have not participated in the preparation of the Registration Statement or the Prospectus and assume no responsibility for their contents.

Based upon the foregoing, and upon our examination of such questions of law and statutes of the State of Delaware as we have considered necessary or appropriate, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that:

1.    The Partnership has been duly formed and is validly existing in good standing as a limited partnership under the Delaware Revised Uniform Limited Partnership Act (6 Del. C. § 17-101, et seq.) (the “LP Act”).

2.    Under the LP Act and the Partnership Agreement, the Partnership has the requisite partnership power and authority to execute and deliver the Indenture and the Debt Securities, and to perform its obligations under the Indenture and the Debt Securities.

3.    Under the LP Act and the Partnership Agreement, the execution and delivery by the Partnership of the Indenture and the Debt Securities, and the performance by the Partnership of its obligations under the Indenture and the Debt Securities, have been duly authorized by the requisite partnership action on the part of the Partnership. Each of the Indenture and the Debt Securities has been duly executed and delivered by the General Partner on behalf of the Partnership.

We understand that you will file this opinion with the Securities and Exchange Commission as an exhibit to Spirit Realty Capital’s and the Partnership’s Current Report on Form 8-K, dated March 3, 2021, which is incorporated by reference in the Registration Statement. In connection with the foregoing, we hereby consent to the filing of this opinion with the Securities and Exchange Commission.
