     ("Bancorp  Common  Stock")  to be issued in the  share  exchange  described
     herein (the "share  exchange")  cannot be precisely  determined at the time
     this  Registration  Statement becomes effective  because  shares of  common

     Bancorp  ("Bancorp  Series A  Preferred  Stock")  to be issued in the share

     pursuant to the Bank's Employee  Stock  Ownership  Plan. This  Registration

     be the average of the reported high and low sales prices of a share of Bank
