        SW 2400      [*]
        SW 2800      [*]
        SW 3200      [*]

        Products returned to Supplier will include a description of the failure
        specified on the RMA field return form provided that such form is
        included by Supplier with each FRU shipment. If the total quantity of
        Product returned to Supplier over the previous [*] exceeds more than [*]
        verified NTF (which shall include both hardware and software failures),
        Buyer will pay Supplier [*] for each verified NTF Product returned in
        accordance with Section 9.2. The reloading of microcode to repair a
        returned Product shall not constitute an NTF."
