This Amendment No. 2 to Schedule 13D relates to shares of Common Stock, par value $0.01 per share (the “Common Stock”), of Hudson Pacific Properties, Inc., a Maryland corporation (the “Issuer”), and amends the initial statement on Schedule 13D filed on April 1, 2015 (the “Original Schedule 13D”), as amended by Amendment No. 1 to the Original Schedule 13D filed on January 5, 2016 (the Original Schedule 13D, as amended, the “Schedule 13D”). Capitalized terms used but not defined in this Amendment No. 2 shall have the same meanings ascribed to them in the Original Schedule 13D.

Item 4. Purpose of Transaction.

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

On May 10, 2016, the Issuer entered into a purchase agreement with the Holdco B Subsidiaries, Nantucket Services L.L.C. and Blackhawk Services II LLC (collectively, the “Blackstone Sellers”), pursuant to which the Issuer agreed to purchase from the Blackstone Sellers an aggregate of 10,000,000 OP Units, at a purchase price of $29.08 per OP Unit (the “Purchase Agreement”). The purchase described above was in connection with the Issuer entering into an underwriting agreement, dated as of May 10, 2016, with the underwriter (the “Underwriter”) and selling stockholders party thereto (the “Underwriting Agreement”), pursuant to which the Issuer agreed to sell 10,117,223 shares of its Common Stock and the selling stockholders party thereto agreed to sell 482,777 shares of Common Stock in an underwritten offering (the “Offering”). The Issuer intended to use the net proceeds received by it in the Offering to purchase the 10,000,000 OP Units from the Blackstone Sellers and 117,223 OP Units from other sellers. The transactions described herein closed on May 16, 2016.

In connection with the Offering, the Blackstone Sellers agreed with the 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 May 10, 2016, except with the prior written consent of the Underwriter (the “Lock-up Agreement”).

References to and descriptions of the 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 Lock-up Agreement, a form of which has been filed as Exhibit F hereto and incorporated herein by reference.

On January 13, 2016, John G. Schreiber, former Partner and Co-Founder of Blackstone Real Estate Advisors, resigned from the Issuer’s board of directors (the “Board”). Mr. Schreiber was appointed to the Board in April 2015 as one of three director nominees of the Sponsor Stockholders pursuant to the terms of the Stockholders Agreement. The Sponsor Stockholders have indicated to the Issuer that they would not designate an individual to replace Mr. Schreiber.

Pursuant to the terms of the limited partnership agreement of the Operating Partnership, and subject to certain requirements and restrictions, OP Units are redeemable for shares of Common Stock, on a one-for-one basis, or, at the option of the Issuer, cash.
