     the Pledged Collateral or such other collateral, if any, it may now or
     hereafter be given to secure the payment of this Note, and no other assets
     of Payor shall be subject to levy, execution or other enforcement procedure

     days after the holder of this Note notifies Payor of such failure;

 
(ii)  Payor fails to perform or observe any other provision contained in this
