amended  except by an  instrument in writing  signed by the parties.  No term or
condition  of this  Agreement  will be  deemed to have  been  waived,  except by

each such waiver will operate only as to the specific  term or condition  waived

to any act other than that specifically waived.

is held invalid,  such  invalidity  will not affect any other  provision of this
Agreement,  and each  provision  will to the  full  extent  consistent  with law
