Parent is an affiliate of Blackstone Real Estate Partners VIII L.P.

Upon the Partnership Merger Effective Time, the Partnership, as the surviving partnership in the Partnership Merger, issued an aggregate 6,025,690 Series B Preferred Units to former holders of Class A Units, who, in lieu of the cash consideration, had validly elected to receive newly issued Series B Preferred Units of the Partnership Merger in exchange for all or a portion of the Class A Units of the Partnership held by them. The Series B Preferred Units are not convertible into, or exchangeable for, any other equity securities and were issued in a private placement in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder.
