NOTES:

      (1)   Basic  earnings  per common share is computed by dividing net income
            applicable to common  stockholders  by the average  number of common
            shares  outstanding.  The computation of diluted earnings per common
            share assumes that the average  number of common shares  outstanding
            is increased by dilutive common share equivalents.

      (2)   Potentially  dilutive  securities at June 30, 1999  included  shares
            issuable pursuant to certain stock-based compensation  arrangements.
            These  securities  included 319,500 shares issuable upon the vesting
            of the  restricted  share units as well as 155,000  shares  issuable
            upon the  exercise of stock  options  calculated  using the treasury
            stock method.
