Item 8.01. Other Events.

On April 10, 2015, certain funds affiliated with Farallon Capital Management, L.L.C. (the “Selling Stockholders”) completed an underwritten public offering of 6,037,500 shares of our common stock (including 787,500 shares of our common stock sold pursuant to the exercise of the underwriters’ option to purchase additional shares in full), $0.01 par value per share (the “Common Stock”), for net proceeds of approximately $198.0 million before expenses. We did not receive any proceeds from the sale of the Common Stock by the Selling Stockholders, but we will pay approximately half of the expenses of the offering, other than underwriting fees, discounts and commissions, which will be borne by the Selling Stockholders.

In connection with the sale of the Common Stock, we entered into an underwriting agreement dated April 6, 2015, among us, our operating partnership, Hudson Pacific Properties, L.P. (the “Operating Partnership”), the Selling Stockholders and Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC (the “Underwriting Agreement”). The Underwriting Agreement contains customary representations and warranties of the parties, and indemnification and contribution provisions under which the Company and the Operating Partnership have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Pursuant to the Underwriting Agreement, we and the Selling Stockholders have agreed not to sell or transfer any shares of Common Stock or any securities convertible into or exercisable or exchangeable for the Common Stock for 30 days after April 6, 2015 without first obtaining the written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC. 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 automatically effective shelf registration statement filed with the Securities and Exchange Commission on March 16, 2015 (File No. 333-202799), a base prospectus dated March 16, 2015 and a prospectus supplement dated April 6, 2015 filed with the Securities and Exchange Commission 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.
