   At March 15, 2000, there were outstanding 21,771,726 shares of the Common
   Stock of Registrant and the aggregate market value of the shares held on that
   date by non-affiliates of Registrant, based on the closing price ($11.81 per
   share) of the Registrant's Common Stock on the NASDAQ National Market, was
   $254,913,750. For purposes of this computation, it has been assumed that the
   shares beneficially held by directors and officers of Registrant were "held
   by affiliates;" this assumption is not to be deemed to be an admission by
   such persons that they are affiliates of Registrant.
