option, (i) by written notice to Maker, declare the entire unpaid balance of 
this Note immediately due and payable regardless of any prior forbearance,

applicable law, including, without limitation, the right to collect from

Default Maker shall pay to Payee, as liquidated damages, and not as a 
penalty, the aggregate amount of the unpaid installments then owed hereunder, 
plus all reasonable costs and expenses incurred by or on behalf of Payee in 
connection with Payee's exercise of any or all of its rights and remedies 
under this Note, including, without limitation, reasonable attorneys' fees.

respect to any amount due hereunder, then from and after the date of such 
judgment, any such overdue amount shall bear interest at a PER ANNUM rate

hereto or 6% until the date of payment.

      3.1  WAIVER

      The rights and remedies of Payee under this Note shall be cumulative 
and not alternative.  No waiver by Payee of any right or remedy under this 
Note shall be effective unless in a writing signed by Payee.  Neither the 
failure nor any delay in exercising any right, power or privilege under this 
Note will operate as a waiver of such right, power or privilege and no single 
or partial exercise of any such right, power or privilege by Payee will 
preclude any other or further exercise of such right, power or privilege or 
the exercise of any other right, power or privilege.  To the maximum extent 
permitted by applicable law, (a) no claim or right of Payee arising out of 
this Note can be discharged by Payee, in whole or in part, by a waiver or 
renunciation of the claim or right unless in a writing, signed by Payee; (b) 
no waiver that may be given by Payee will be applicable except in the 
specific instance for which it is given; and (c) no notice to or demand on 
Maker will be deemed to be a waiver of any obligation of Maker or of the 
right of Payee to take further action without notice or demand as provided in 
this Note.  Maker hereby waives presentment, demand, protest and notice of 
dishonor and protest.
