Note 5:
Common Stock

On December 29, 2011, the Company entered into a sales agreement (the "Sales Agreement") with Cowen and Company, LLC to sell shares of the Company's common stock, par value $.01 per share, having aggregate sales proceeds of $39,750,000, from time to time, through an "at the market" equity offering program under which Cowen and Company, LLC will act as sales agent. As of March 31, 2012, the Company had sold approximately 1.4 million shares of its common stock through the program for net proceeds of approximately $4.8 million. The net proceeds were used for general corporate purposes, including, but not limited to, commercialization of our products, obtaining regulatory approvals, funding of our clinical trials, capital expenditures and working capital. As discussed in more detail in Note 4 of this filing, these issuances triggered an adjustment of the exercise price and number of warrant shares under the Company's outstanding warrant agreements. As of March 31, 2012, there was approximately $34.8 million available under this program, assuming sufficient shares are available to be issued.
