Item 1.01 Entry into a Material Definitive Agreement.

On June 26, 2014, Healthcare Trust of America Holdings, LP (the “Operating Partnership”), the operating partnership subsidiary of Healthcare Trust of America, Inc. (NYSE: HTA) (“HTA” and together with the Operating Partnership, the “Company”), issued $300.0 million in aggregate principal amount of its 3.375% Senior Notes due 2021 (the “Notes”) in a public offering through underwriters for whom Wells Fargo Securities, LLC, J.P. Morgan Securities LLC and Jefferies LLC acted as representatives (the “Representatives”) pursuant to an underwriting agreement dated June 23, 2014 (the “Underwriting Agreement”) among the Operating Partnership, HTA and the Representatives. The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the underwriters, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties and termination provisions. A copy of the Underwriting Agreement is attached as Exhibit 1.1 to this report.

The Notes were registered under the Securities Act, on the Company’s automatic shelf registration statement on Form S-3ASR (File No. 333-196693), filed with the Securities and Exchange Commission on June 12, 2014. The Notes were issued pursuant to an indenture (the “Indenture”), dated as of June 26, 2014, among the Operating Partnership, as issuer, HTA, as guarantor, and U.S. Bank National Association, as trustee. The Indenture contains various restrictive covenants, including limitations on the Operating Partnership’s ability to incur additional indebtedness, requirements to maintain a pool of unencumbered assets and requirements to maintain insurance with financially sound and reputable insurance companies.

A copy of the Indenture, including the form of the Notes and guarantee of the Notes by HTA, the terms of which are incorporated herein by reference, is attached as Exhibits 4.1 to this report. See Item 2.03 below for additional information.

The net proceeds of this offering will be approximately $295.5 million, after deducting the underwriting discount and estimated offering expenses. The Operating Partnership intends to use the net proceeds of the offering of the Notes (i) to repay in full the outstanding indebtedness under the revolving credit facility of its senior unsecured revolving credit and term loan facility and up to $125 million of secured mortgage debt and any associated prepayment penalties and (ii) for general corporate purposes, including, without limitation, working capital and investment in real estate.

The foregoing description of the Underwriting Agreement, the Indenture and the Notes is qualified in its entirety by reference to the Underwriting Agreement, the Indenture and the forms of Notes and guarantee of the Notes therein, attached hereto as Exhibits 1.1 and 4.1, respectively, and incorporated by reference herein.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On June 26, 2014, the Operating Partnership issued $300.0 million in aggregate principal amount of Notes. The Operating Partnership offered the Notes at 99.205% of the principal amount thereof. The Notes are general unsecured and unsubordinated obligations and will rank equally in right of payment with all of the Operating Partnership’s existing and future senior unsecured indebtedness, including the Operating Partnership’s 3.70% Senior Notes due 2023, and senior in right of payment to any of the Operating Partnership’s subordinated indebtedness. As a result, the Notes will be effectively subordinated in right of payment to all of the Operating Partnership’s existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness and structurally subordinated in right of payment to all existing and future liabilities and other indebtedness, whether secured or unsecured, of the Operating Partnership’s subsidiaries. The Notes bear interest at 3.375% per annum. Interest is payable on January 15 and July 15 of each year beginning January 15, 2015 until the maturity date of July 15, 2021. The Operating Partnership’s obligations under the Notes are fully and unconditionally guaranteed by HTA. A copy of the Indenture, including the form of the Notes and guarantee of the Notes by HTA, the terms of which are incorporated herein by reference, is attached as Exhibit 4.1 to this report.

The Notes will be redeemable at the Operating Partnership’s option and in its sole discretion, at any time or from time to time prior to July 15, 2021, in whole or in part, at a redemption price equal to the greater of:

plus, in each case, accrued and unpaid interest thereon to the applicable redemption date; provided, however, that if the redemption date falls after a record date and on or prior to the corresponding interest payment date, the Operating Partnership will pay the full amount of accrued and unpaid interest, if any (plus additional interest, if applicable), on such interest payment date to the holder of record at the close of business on the corresponding record date (instead of the holder surrendering its Notes for redemption).

Notwithstanding the foregoing, if the Notes are redeemed on or after May 15, 2021 (60 days prior to the maturity date), the redemption price will be equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to the applicable redemption date.

Certain events are considered events of default, which may result in the accelerated maturity of the Notes, including:
