On April 5, 2016, Healthcare Trust of America, Inc. (NYSE: HTA) (“HTA”) and Healthcare Trust of America Holdings, LP, the operating partnership subsidiary of HTA (the “Operating Partnership” and together with HTA, the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”) with Wells Fargo Securities, LLC and J.P. Morgan Securities LLC, as underwriters (the “Underwriters”), for an underwritten public offering of 5,200,000 shares of HTA’s Class A common stock, $0.01 par value per share (the “Common Stock”), at a purchase price to the Underwriters of $28.75 per share (the “Offering”). HTA has granted the Underwriters a 30-day option to purchase up to 780,000 additional shares of its Common Stock at a purchase price of $28.75 per share. The Underwriters may offer the shares of Common Stock in transactions on the NYSE, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The Offering closed on April 11, 2016.

The Underwriting Agreement includes customary representations, warranties and covenants by the Company. It also provides for customary indemnification by each of the Company and the Underwriters party to the agreement against certain liabilities arising out of or in connection with the Offering and for customary contribution provisions in respect of those liabilities.

In connection with the Offering, the directors and executive officers of HTA have agreed to enter into 60-day “lock-up” agreements in substantially the form attached to the Underwriting Agreement, subject to certain exceptions.

The Company received $149.5 million in gross proceeds, before deducting estimated offering expenses. The Company intends to use net proceeds from the Offering for general corporate purposes, including, without limitation, working capital, funding a portion of pending real estate acquisitions and repayment of debt.

The Offering was made pursuant to an automatic shelf-registration statement filed with the Securities and Exchange Commission (the “SEC”) on February 27, 2015 (File No. 333-202388), a base prospectus, dated February 27, 2015, included as part of the registration statement, and a prospectus supplement, dated April 5, 2016, filed on April 7, 2016, pursuant to Rule 424(b) under the Securities Act of 1933, as amended.

The foregoing description of the Underwriting Agreement is intended to be a summary and is qualified in its entirety to the terms of the Underwriting Agreement, attached hereto as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 8.01.
