Fox, Jr., as selling stockholders (Compass, together with Mr. Fox, the “Selling Stockholders”). Pursuant to the Underwriting Agreement, Compass agreed to sell 3,500,000 shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”) owned or beneficially held by Compass (the “Offering Shares”), to the Underwriter at a price of $18.00 per share, and Mr. Fox granted the Underwriter an over-allotment option to purchase up to 525,000 shares of the Company’s Common Stock owned by Mr. Fox (the “Option Shares”) at a price of $18.00 per share, which the Underwriter exercised in full.

The Underwriting Agreement contains customary representations, warranties, and covenants of the Company and the Selling Stockholders and also provides for customary indemnification by each of the Company, the Selling Stockholders, and the Underwriter against certain liabilities and customary contribution provisions in respect of those liabilities.

The offering and sale of the Common Stock by the Selling Stockholders was made pursuant to the Company’s Registration Statement on Form S-3 (Registration No. 333-203146) (the “Registration Statement”), including a prospectus supplement dated August 8, 2016 to the base prospectus contained in the Registration Statement, filed by the Company with the Securities and Exchange Commission pursuant to Rule 424(b)(7) under the Securities Act of 1933, as amended. The sale of the Offering Shares pursuant to the Underwriting Agreement closed on August 12, 2016.

The foregoing description of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement, a copy of which is attached hereto as Exhibit 1.1 and incorporated herein by reference.

On August 12, 2016, the Company closed the secondary public offering by the Selling Stockholders of an aggregate 4,025,000 shares of Common Stock. A copy of the press release announcing the closing of the offering is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
