Registered Direct Offering

On May 23, 2017, the Company entered into Common Stock Purchase Agreements (the “Purchase Agreements”) with certain investors to which the Company sold, in the aggregate, 4,008,273 shares of common stock in a registered direct offering pursuant to a shelf registration statement on Form S-3 (File No. 333-203209), filed with the Securities and Exchange Commission on May 13, 2015. The offering was led by a new private investor who the Company believes will add strategic value. The shares were sold at a price of $1.12 per share, except for shares purchased by investors who are directors or executive officers of the Company, which were sold at a price of $1.15 per share. The Company did not market this equity offering to any additional new investors and the Company did not use an underwriter on the offering. The closing of this sale occurred on May 30, 2017 and the Company received gross proceeds of approximately $4.5 million. The Company plans to use the proceeds for general working capital purposes.
