Re: Securities Registered under Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to you in connection with your filing of a Registration Statement on Form S-3 (File No. 333-190543) (as amended or supplemented, the “Registration Statement”) filed on August 9, 2013 with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of (i) debt securities (the “Debt Securities”) of MPT Operating Partnership, L.P., a Delaware limited partnership, and MPT Finance Corporation, a Delaware corporation (the “Issuers”) and (ii) the guarantees of the Debt Securities (the “Guarantees”) by Medical Properties Trust, Inc., a Maryland corporation (the “Parent Guarantor”) and certain subsidiaries of the Parent Guarantor named in Schedule 1 (the “Subsidiary Guarantors,” and together with the Parent Guarantor, the “Guarantors”). The Debt Securities and the Guarantees are collectively referred to herein as the Securities. The Registration Statement became effective upon filing with the Commission on August 9, 2013. Reference is made to our opinion letter dated August 9, 2013 and included as Exhibit 5.1 to the Registration Statement. We are delivering this supplemental opinion letter in connection with the prospectus supplement (the “Prospectus Supplement”) filed on September 27, 2013 by the Issuers and the Guarantors with the Commission pursuant to Rule 424 under the Securities Act. The Prospectus Supplement relates to the offering by the Issuers of €200,000,000 aggregate principal amount of Debt Securities in the form of 5.750% Senior Notes due 2020 (the “Notes”) and the guarantees thereof by the Guarantors (the “Note Guarantees”). We understand that the Notes and the Note Guarantees are to be offered and sold in the manner described in the Prospectus Supplement.

We have reviewed such documents and made such examination of law as we have deemed appropriate to give the opinions set forth below. We have relied, without independent verification, on certificates of public officials and, as to matters of fact material to the opinions set forth below, on certificates of officers of the Parent Guarantor.

We refer to the Indenture, to be dated on or about October 10, 2013, that is to be entered into by the Issuers, certain subsidiaries of the Parent Guarantor and Wilmington Trust, National Association, as trustee (the “Trustee”), and to be amended by the First Supplemental Indenture (the “First Supplemental Indenture”), to be dated on or about October 10, 2013, that is to be entered into by the Issuers, the Guarantors and the Trustee, establishing the terms of the Notes and the Note Guarantees thereunder, in a form consistent with that authorized by the Issuers, as the “Indenture.”
