(10) Net Loss per Common Share Applicable to Common Stockholders

For the three and nine months ended September 30, 2012 and 2011, basic and diluted net loss per common share applicable to common stockholders is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net loss per common share applicable to common stockholders is the same as basic net loss per common share applicable to common stockholders as the effects of the Company’s potential common stock equivalents are antidilutive. Total antidilutive securities were 16,021,649 and 6,266,804 for the nine months ended September 30, 2012 and 2011, respectively, and consist of stock options, preferred stock and warrants.

For the three and nine months ended September 30, 2012, net loss per common share applicable to common stockholders reflects $160,000 and $480,000, respectively, in dividends payable on shares of our Series D redeemable convertible preferred stock that were issued in November 2011.
