Ladies and Gentlemen:

We have acted as special counsel to Healthcare Trust of America, Inc., a Maryland corporation (the “Company”), and Healthcare Trust of America Holdings, LP, a Delaware limited partnership (the “Operating Partnership”), in connection with the issuance and sale by the Operating Partnership of $250,000,000 aggregate principal amount of its 3.500% Senior Notes due 2026 (the “2026 Notes”) and $650,000,000 aggregate principal amount of its 3.100% Senior Notes due 2030 (the “2030 Notes” and, collectively with the 2026 Notes, the “Notes”) pursuant to an underwriting agreement, dated September 5, 2019, by and among the Company and the Operating Partnership, on the one hand, and BofA Securities, Inc., J.P.

1.The Notes have been duly authorized by all necessary corporate action on the part of the Operating Partnership, and, upon payment for and delivery of the Notes in accordance with the terms of the Indentures and the authentication of the certificate or certificates representing the Notes by a duly authorized signatory of the Trustee, will be legally valid and binding obligations of the Operating Partnership, enforceable against the Operating Partnership, in accordance with their terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or 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 considered in a proceeding at law or in equity.

2.    Upon delivery of the Guarantees in accordance with the terms of the Indentures, the Guarantees will be legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or 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 considered in a proceeding at law or in equity.
