Net Loss per Share

5. Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Diluted loss per share is computed using the weighted-average number of common shares outstanding during the period, plus the dilutive effect of outstanding options and warrants, using the treasury stock method and the average market price of our common stock during the applicable period.

Certain shares related to some of the Company's outstanding common stock options, unvested restricted stock and warrants, have not been included in the computation of diluted net loss per share for the three and nine months ended September 30, 2010 and 2009 as the result would be antidilutive.  Such potential common shares at September 30, 2010 and 2009 consist of the following:
