    (a) Requirements for control. A secured party has control of a deposit

             is maintained;
         (2) the debtor,  secured  party,  and  bank  have  agreed  in  an
             authenticated   record   that   the  bank  will  comply  with
             instructions  originated  by  the  secured  party   directing
             disposition  of  the  funds  in  the  deposit account without
             further consent by the debtor; or
         (3) the secured party becomes the bank's customer with respect to
             the deposit account.
