Pursuant to the Underwriting Agreement, Compass agreed to sell 2,500,000 shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”), held by Compass (the “Offering Shares”) to the Underwriter at a price of $15.895 per share, and Mr. Fox granted the Underwriter an over-allotment option to purchase up to 375,000 shares of the Company’s Common Stock owned by Mr. Fox (the “Option Shares”) at a price of $15.895 per share.

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 sale of the Offering Shares pursuant to the Underwriting Agreement closed on March 16, 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 March 16, 2016, concurrently with the closing of the Company’s secondary public offering of the 2,500,000 Offering Shares held by Compass, the Company closed on a repurchase of 500,000 shares of the Company’s Common Stock held by Compass, as previously disclosed on a Current Report on Form 8-K filed on March 15, 2016.
