EARNINGS PER COMMON SHARE

Earnings per common and common equivalent shares are computed by dividing net
income applicable to common stock by the total of the average number of common
shares outstanding and the additional dilutive effect of stock options
outstanding during the respective period.  The dilutive effect of stock options
is computed using the average market price of the common stock for the period
for primary earnings per share.

Earnings per common share, assuming full dilution, are computed by dividing net
income by the average number of common shares outstanding during the period, the
dilutive effect of the Convertible Preferred Stock assuming conversion at the
time it was issued, and the additional dilutive effect of stock options
outstanding during the period.  The dilutive effect of outstanding stock options
is computed using the greater of the closing market price or the average market
price of the common stock for the period.

Earnings per common share have been computed based on the following:
