     1993 Employee Stock Purchase Plan, solely for the purpose of calculating
     the registration fee. No options have been granted with respect to such
     shares. The computation is based upon the average of the high and low price
     of the Common Stock as reported on the Nasdaq National Market on February
     19, 2002 because the price at which the options to be granted in the future
     may be exercised is not currently determinable.

     may be exercised is not currently determinable.
