Agreement shall be promptly reported to Seller or Buyer, as applicable, and

such errors or discrepancies occurred, the same shall be conclusively deemed to
be correct.
     (C)  If either party fails to pay any Undisputed Amount when due, the
other party may, upon written notice, suspend performance of its obligations
hereunder, and should such nonpayment continue for a period of thirty days
after such notice, terminate this Agreement upon written notice to the other.
