LLC, as representatives of the several underwriters set forth on Schedule 1 thereto (the “Underwriters”), relating to an underwritten public offering of 18,367,347 shares (the “Underwritten Shares”) of the Company’s common stock, par value $0.01 per share (the “Offering”). The price to the public in this Offering is $12.25 per share, and the Underwriters agreed to purchase the Underwritten Shares from the Company pursuant to the Underwriting Agreement at a price of $11.515 per share.

In addition, under the terms of the Underwriting Agreement, the Company granted the Underwriters an option, exercisable for 30 days after July 13, 2017, to purchase up to an additional 2,755,102 shares of the Company’s common stock (the “Option Shares”, and together with the Underwritten Shares, the “Shares”) at a price of $11.515.

The net proceeds from the sale of the Underwritten Shares, after deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, will be approximately $211.5 million.

The Offering is being made pursuant to the Company’s registration statement on Form S-3 (Registration No. 333-211005) filed with the U.S. Securities and Exchange Commission (the “Commission”) on April 29, 2016, which became effective automatically upon the filing thereof.
