18.  Loss Per Common Share

Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding for the period.  Diluted loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding, adjusted for shares that would be assumed outstanding after warrants and stock options vested under the treasury stock method.  At December 31, 2013 and 2012, outstanding warrants convertible into 161,800 and 440,400 shares, respectively, of Common Stock were excluded from the calculation of diluted loss per share because their impact would have been anti-dilutive.  At December 31, 2013 and 2012, there were outstanding stock options to purchase 60 and 260 shares of Common Stock, respectively, which were also excluded from the calculation of diluted loss per share because their impact would have been anti-dilutive.
