13. STOCKHOLDERS’ EQUITY

Common Stock Activity

During the year ended September 30, 2013, the Company issued 526,206 shares of common stock and obtained gross proceeds of $340,450 in connection with the exercise of stock options.

Preferred Stock

The Company is authorized under its certificate of incorporation and bylaws to issue 5,000,000 shares of preferred stock, $0.00001 par value, without any further action by the stockholders. The board of directors has the authority to divide any and all shares of preferred stock into series and to fix and determine the relative rights and preferences of the preferred stock, such as the designation of series and the number of shares constituting such series, dividend rights, redemption and sinking fund provisions, liquidation and dissolution preferences, conversion or exchange rights and voting rights, if any. Issuance of preferred stock by the board of directors could result in such shares having dividend and or liquidation preferences senior to the rights of the holders of common stock and could dilute the voting rights of the holders of common stock.

No shares of preferred stock were outstanding during the fiscal years ended September 30, 2013 or 2012.

Stock Purchase Warrants

At September 30, 2013 and 2012, the Company had 1,627,945 shares purchasable under outstanding warrants at an exercise price of $2.67 which are exercisable through February 4, 2016.
