Item 8.01. Other Events.

On July 21, 2016, the Company and certain funds affiliated with Farallon Capital Management, L.L.C. (the “Selling Stockholders” or the “Farallon Funds”) completed an underwritten public offering of 20,000,000 shares of common stock of the Company, $0.01 par value per share (the “Common Stock”), consisting of 19,195,373 shares offered by the Company and 804,627 shares offered by the Selling Stockholders. The offering generated net proceeds for the Company and the Selling Stockholders of approximately $582.0 million and $24.4 million, respectively, before expenses. The Company did not receive any proceeds from the sale of the Common Stock by the Selling Stockholders but will pay approximately half of the expenses of the offering with respect to the shares of Common Stock sold by the Selling Stockholders, other than underwriting discounts, which will be borne by the Selling Stockholders.

In connection with the offering, the Company entered into an underwriting agreement, dated July 18, 2016 (the “Underwriting Agreement”), among the Company, the Operating Partnership, the Selling Stockholders and Merrill Lynch, Pierce, Fenner & Smith Incorporated (the “Underwriter”). The Underwriting Agreement contains customary representations and warranties of the parties, and indemnification and contribution provisions under which the Company, the Operating Partnership and the Selling Stockholders have agreed to indemnify the Underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Pursuant to the Underwriting Agreement, the Company has agreed, subject to certain exceptions, not to sell or transfer any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock for 30 days after July 18, 2016 without first obtaining the written consent of the Underwriter. A copy of the Underwriting Agreement is attached as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The offering was made pursuant to an effective shelf registration statement filed with the Securities and Exchange Commission (the “SEC”) on March 16, 2015 (File No. 333-202799), a base prospectus, dated March 16, 2015, included as part of the registration statement, and a prospectus supplement, dated July 18, 2016, filed with the SEC pursuant to Rule 424(b) under the Securities Act. We are filing as Exhibit 5.1 to this Current Report on Form 8-K an opinion of our counsel, Venable LLP, regarding certain Maryland law issues concerning the shares of Common Stock sold in the offering.

On July 21, 2016, the Company used the net proceeds of the offering, after deducting underwriting discounts, but before estimated offering expenses payable by the Company, to acquire an aggregate of 19,000,000 common units of partnership interest in the Operating Partnership (the “Common Units”) from certain entities affiliated with The Blackstone Group L.P. and 195,373 Common Units from the Farallon Funds.
