of this  Agreement are for the  convenience  of reference only and are not to be
considered in construing this Agreement.

held to be unenforceable  under applicable law, the parties agree to renegotiate
such  provision  in good faith to achieve  the  closest  comparable  terms as is

enforceable  replacement  for such  provision,  then (a) such provision shall be
excluded  from  this  Agreement,  (b) the  balance  of the  Agreement  shall  be
interpreted  as if such  provision  were so excluded  and (c) the balance of the
Agreement shall be enforceable in accordance with its terms.
