We are entitled under our certificate of incorporation to issue up to 175 million shares of common stock, par value $.001 per share, and 1 million shares of preferred stock, with no par value. As of June 30, 2014, we had issued and outstanding approximately 65.6 million shares of common stock, and 8.8 million and 8.5 million warrants and options, respectively, to purchase shares of common stock. Additionally, we had approximately 6.5 million shares of common stock reserved for future issuance of additional option grants under our 2008 Omnibus Equity Incentive Plan. Accordingly, we will be able to issue up to approximately 85.6 million additional shares of common stock and 1.0 million shares of preferred stock. Sales of our common stock offered through current or future equity offerings may result in substantial dilution to our stockholders. The sale of a substantial number of shares of our common stock to investors, or anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales. |
