     Public Offering of Common Stock

     On July 5, 2011, the Company closed a public offering in which it sold 3,053,750 shares, including 408,750 shares pursuant to the Underwriters over-allotment option, and the Selling Stockholders sold 80,000 shares. The shares were sold at a price of $3.5208 per share, representing a discount to the public offering price of $3.75 per share. The net proceeds of the offering to the Company were $10.1 million after deducting underwriting discounts and commissions and offering expenses. The Company did not receive any proceeds from shares sold by the Selling Stockholders.

     In accordance with the Underwriting Agreement, the Company issued 61,076 common stock warrants (2.0% of the share issued by the Company in the offering) with an exercise price equal to $4.50 (120% of the public offering price), and which have a term of not greater than five years from June 28, 2011 (the date of the final prospectus for the public offering).
