8. Net Loss per Share

Net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted loss per share is computed by dividing net loss by the weighted average number of common shares outstanding including the effect of common share equivalents. All common equivalent shares were anti-dilutive at September 30, 2014 and 2013, as such there is no separate computation for diluted loss per share. The number of options and warrants for the purchase of common stock, that were excluded from the computations of net loss per common share for the nine months ended September 30, 2014 were 5,786,106 and 944,986, respectively, and for the nine months ended September 30, 2013 were 3,804,580 and 1,632,501, respectively.
