The Bonds have been issued pursuant to the Company’s Indenture, Deed of Trust and Security Agreement, dated as of October 1, 2008, between the Company and The Bank of New York Mellon, as trustee, (the “Trustee”) (the Indenture, Deed of Trust and Security Agreement, as amended and supplemented, including by the officer’s certificate dated as of May 11, 2026 establishing the terms of the Bonds, being hereinafter referred to as the “Mortgage”), and will be sold to the underwriters under the Underwriting Agreement dated May 11, 2026 (the “Underwriting Agreement”) among the Company and BNP Paribas Securities Corp., BNY Mellon Capital Markets, LLC, KeyBanc Capital Markets Inc., MUFG Securities Americas Inc., Regions Securities LLC, and R. Seelaus & Co., LLC.

We, as your special Texas counsel, have examined originals or copies of (i) the Registration Statement, (ii) the Amended and Restated Certificate of Formation of the Company, (iii) the Amended and Restated Company Agreement of the Company (the “Company Agreement”), (iv) a statement of Franchise Tax Account Status dated as of May 5, 2026 obtained through the website of the Office of the Comptroller of Public Accounts of Texas, which statement expressly states that, as of the date thereof, the right of the Company to transact business in Texas is “active”, (v) the Underwriting Agreement, (vi) the Mortgage, which has been (or will be) filed with the Securities and Exchange Commission as an exhibit to the Registration Statement, and (vii) the records of various actions previously taken by the Company’s Board of Directors relating to the authorization, issuance and sale of the Bonds by the Company and the execution and delivery by the Company of the officer’s certificate establishing the terms of the Bonds (“Corporate Proceedings”), and certifications of the Corporate Proceedings taken to date by the Company in connection with the Offering in a

certificate dated as of even date herewith. As to questions of fact material to the opinions expressed herein, we have relied upon representations and certifications of officers of the Company and appropriate public officials without independent verification of such matters except as otherwise described herein. We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials, and other instruments as we have deemed necessary for the purposes of rendering this opinion. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to the originals of the documents submitted to us as certified, facsimile or electronic copies and the authenticity of the originals of such latter documents and the enforceability of all documents submitted to us against parties other than the Company. We have also assumed that there has been no oral or written modification of or amendment to any of the documents we have reviewed, that there has been no waiver of any provision of any of such documents, by action or omission of the parties or otherwise, and that the Bonds will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the Prospectus. Furthermore, we have not examined the Bonds, except a specimen thereof, and we have relied upon a certificate of the Trustee as to the authentication and delivery thereof.

Subject to the qualifications hereinafter expressed, we are of the following opinion:

The Bonds are binding obligations of the Company, subject to (i) applicable bankruptcy, insolvency, usury, fraudulent conveyance, receivership, fraudulent transfer, preference, moratorium, reorganization or other similar laws affecting enforcement of mortgagees’ and other creditors’ rights and by general equitable principles (whether considered in a proceeding in equity or at law), including the possible unavailability of specific performance or injunctive relief, and (ii) concepts of materiality, reasonableness, good faith and fair dealing and the discretion of the court before which any proceeding therefor may be brought.

This opinion is limited to the laws of the State of Texas. To the extent that this opinion relates to or is dependent upon matters governed by the laws of the State of New York or the federal laws of the United States of America, we have relied upon the opinion of even date herewith addressed to you by Morgan, Lewis & Bockius LLP, subject to the assumptions therein, which opinion is being filed as Exhibit 5.10 to the Registration Statement. We express no opinion with respect to those matters herein, and to the extent elements of that opinion are necessary to the conclusions expressed herein, we have, with your consent, assumed such matters. As to all matters of the laws of the State of Texas, Morgan, Lewis & Bockius LLP is authorized to rely on this opinion as if it were addressed to them.

We express no opinion as to the effects, if any, of the federal securities laws and regulations, the “blue sky” laws of the State of Texas and the “blue sky” laws of other states, or federal tax laws, rules or regulations. We express no opinion except as explicitly provided herein, and our opinions are expressed as of the date hereof and are based, in each case, upon existing laws and regulations effective as of the date hereof and assume the application of such laws and regulations to events that may occur after the date of this letter. We undertake no obligation (a) to advise you of changes that may come to our attention or that become effective after the date hereof or (b) to withdraw, reissue, or supplement the opinions expressed herein as a result of any subsequent change to relevant facts or applicable law or any discovery by us that any assumption or factual conclusion set forth in this letter was incorrect as of the date hereof.
