Earnings Per Common Share (EPS)
  
Basic EPS is calculated using net loss divided by the weighted average of common shares outstanding.  Diluted EPS is calculated similarly to Basic EPS except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if the potential dilutive common shares, such as those shares subject to options, had been issued.  The options disclosed in Note
5
 have been excluded from the computation because of their antidilutive effect. 
 
Shares used in the calculation of diluted EPS are summarized below:
