     Note:
         Basic earnings per common share was computed by dividing net income,
         reduced by preferred stock dividend requirements, by the weighted
         average of the number of shares of common stock outstanding during each
         period.

         Diluted earnings per common share was computed on the assumption that
         all convertible debentures, convertible preferred stock, and stock
         options converted or exercised during each period, or outstanding at
         the end of each period were converted at the beginning of each period
         or the date of issuance or grant, if dilutive. The computation provides
         for the elimination of related convertible debenture interest and
         preferred dividends.
