Capitalized terms used but not defined in this Amendment No. 3 shall have the same meanings ascribed to them in the Schedule 13D.

Item 4.

Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

On July 18, 2016, the Issuer entered into a purchase agreement with the Blackstone Sellers, pursuant to which the Issuer agreed to purchase from the Blackstone Sellers an aggregate of 19,000,000 OP Units, at a purchase price of $30.32 per OP Unit (the “July 2016 Purchase Agreement”). The purchase described above was in connection with the Issuer entering into an underwriting agreement, dated as of July 18, 2016, with the underwriter (the “July 2016 Underwriter”) and selling stockholders party thereto (the “July 2016 Underwriting Agreement”), pursuant to which the Issuer agreed to sell 19,195,373 shares of its Common Stock and the selling stockholders party thereto agreed to sell 804,627 shares of Common Stock in an underwritten offering (the “July 2016 Offering”). The Issuer intended to use the net proceeds received by it in the July 2016 Offering to purchase the 19,000,000 OP Units from the Blackstone Sellers and 195,373 OP Units from other sellers. The transactions described herein closed on July 21, 2016.

In connection with the July 2016 Offering, the Blackstone Sellers agreed with the July 2016 Underwriter, subject to specified exceptions, not to offer, pledge or sell, or enter into any agreement to sell or otherwise dispose of or transfer, any shares of Common Stock or securities convertible into or exchangeable or exercisable for shares of Common Stock, for a period of 30 days after July 18, 2016, except with the prior written consent of the July 2016 Underwriter (the “July 2016 Lock-up Agreement”).

References to and descriptions of the July 2016 Lock-up Agreement set forth above in this Item 4 do not purport to be complete and are qualified in their entirety by reference to the full text of the July 2016 Lock-up Agreement, a form of which has been filed as Exhibit G hereto and incorporated herein by reference.
