          ----------------------
     the preamble of this Agreement are hereby incorporated into and made a
     material part of this Agreement.

          ----------
     or enforce strict performance of any provision of this Agreement or to
     exercise any rights or remedies thereunder will not be construed as a
     waiver by such party to assert or rely upon any such provision, right or
     remedy in that or any other instance.
