unenforceable in any jurisdiction shall be, as to such jurisdiction,

interest in, to or under any of the accounts receivables, as defined in

the monies due it to a third party. SELLER, upon receiving notice of any such 
assignment, agrees to abide thereby and make payments or direct SELLER'S 
customers and Account Debtors to make payment as may therein be directed. In 
the event of any such full or partial assignment by PURCHASER, SELLER shall 
have no recourse against PURCHASER'S Assignee. SELLER agrees that any claim 
which may arise by SELLER shall be made against PURCHASER only and waives any 
rights it may have against PURCHASER'S Assignee.
