     Note:
              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. This computation provides for the elimination of related
              convertible debenture interest and preferred dividends.
