covenants  herein set  forth,  and other good and  valuable  consideration,  the
receipt and sufficiency of which are hereby  acknowledged,  and as an inducement

the  Obligations,  ratably and without  priority of one over  another.  The term

amount not to exceed Three  Hundred  Fifty  Thousand  Dollars  ($350,000.00  US)

interest granted  hereunder as to any other security  interest in the collateral
granted by the Debtor to the bank or any other  person or  entity.  The  Secured
Party's  reasonable  out-of-pocket  expenses  incurred in  connection  with such
subordination shall be paid by Debtor from the proceeds of the line of credit.
