Common Stock - "At-The-Market" Equity Program

On January 21, 2016, the Company entered into a Controlled Equity Offering™ Sales Agreement (the “ATM Agreement”) with Cantor Fitzgerald & Co. (“Cantor Fitzgerald”) to implement an "At-The-Market" (“ATM”) equity program under which the Company, from time to time, may offer and sell shares of its common stock having an aggregate offering price of up to $50.0 million (the “Shares”) through Cantor Fitzgerald.

Subject to the terms and conditions of the Agreement, Cantor Fitzgerald will use its commercially reasonable efforts to sell the Shares from time to time, based upon the Company’s instructions. The Company has no obligation to sell any of the Shares, and may at any time suspend sales under the ATM Agreement or terminate the ATM Agreement. Cantor Fitzgerald will be entitled to a fixed commission of up to 3.0% of the gross proceeds from Shares sold.
