    enforcement is considered in a proceeding at law or in equity.

     4.   In accordance with the provisions of clause (j) of Section 7.2.2 of
                                                             -------------

event that any payment is made by the Borrower to us that is not permitted by
such provisions so to be made, in whole or in part, to hold the proceeds of such
