8.      Net Loss Per Share

Basic net loss per common share for the three and six months ended June 30, 2011 and 2010 was computed by dividing the net loss attributable to common stockholders for the relevant period by the weighted average number of shares of common stock outstanding. Diluted earnings per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock and common stock equivalents outstanding.

Potential common stock equivalents of approximately 19,324 and 19,804 outstanding stock options, 5.4 million and 9.6 million outstanding stock warrants, 55,000 and 420,000 shares issuable upon conversion of preferred stock and 1.7 million and 5.5 million shares issuable upon conversion of notes are excluded from the diluted earnings per share calculation for the periods ended June 30, 2011 and 2010, respectively, due to their anti-dilutive effect.
