Net Loss Per Common Share
 
Basic loss per share data for each period presented is computed using the weighted-average number of shares of common stock outstanding during each such period. Diluted loss per share data is computed using the weighted-average number of common and dilutive common-equivalent shares outstanding during each period. Dilutive common-equivalent shares consist of: (a) shares that would be issued upon the exercise of stock options and warrants, computed using the treasury stock method; and (b) shares of non-vested restricted stock.
 
The following securities are excluded from the calculation of weighted average dilutive common shares because their inclusion would have been anti-dilutive:
