the provisions of the Form Master Agreement and this  Confirmation,  this  Confirmation  will prevail for the
purpose of this Transaction.

in full force and effect as if this  Agreement had been executed  with the invalid or  unenforceable  portion
eliminated,  so long as this Agreement as so modified  continues to express,  without  material  change,  the
original  intentions  of the  parties as to the subject  matter of this  Agreement  and the  deletion of such
portion of this  Agreement  will not  substantially  impair the respective  benefits or  expectations  of the
parties.

         The  parties  shall  endeavor  to engage in good  faith  negotiations  to  replace  any  invalid  or
unenforceable term, provision,  covenant or condition with a valid or enforceable term,  provision,  covenant

unenforceable term, provision, covenant or condition.

directors, or shareholders (the "NON-RECOURSE PARTIES") shall be personally liable for the payment by or on
