        provisions or terms set forth in this Amendment conflict with the terms set
        forth in the OEM
        Purchase and Supply Agreement ,

        during any calendar quarter, Supplier fails to meet three (3) or more Delivery

        following:
  “ Customer
        Service .  Outside
        of the United States and Canada, customer service calls will be handled by
        GEMS-IT. If a customer calls GEMS-IT with a Product Warranty issue (GEMS-IT
        fields the warranty call), GEMS-IT will
        inform Supplier of the warranty call and will receive a RMA from Supplier.
        GEMS-IT or its customer will return the product for repair or replacement
        to
        Supplier’s facility in Minnetonka, MN or Supplier’s then current facility.
        Supplier will repair or replace the OEM Product and deliver the OEM Product
        to a
        location requested by GEMS-IT within two (2) weeks of Supplier’s receipt of a
        returned OEM Product. Within the United States and Canada, customer service
        calls will be handled directly by Cardiac Science, and all repaired or replaced
        OEM Products must be delivered within two (2) weeks of Supplier’s receipt of a
        returned OEM Product. Supplier and GEMS-IT shall work together to ensure
        prompt
        communication to the other party of all customer communication.
 
 Loaner
        Inventory. Within
        thirty (30) days of this Amendment, Cardiac Science shall provide, at no
        cost to
        GEMS-IT, up to fifteen (15) additional GE Healthcare-branded Responder®
        AEDs and/or
        AED Pros to be used by GEMS-IT as loaner inventory and to facilitate warranty
        exchanges for end users. These units shall be suitably configured with local
        languages as per GEMS-IT instructions.
 
 In
                  all cases, freight charges to and from Supplier’s facility for warranty
                  service and loaner inventory will be paid by Supplier.
 
 3
  Out
        of
        Warranty Service. Outside
        the United States and Canada, if GEMS-IT requires out of warranty service
        from
        Cardiac Science, GEMS-IT will bill the customer as appropriate per GEMS-IT
        policies. GEMS-IT will inform Supplier of the customer issue and will receive
        a
        RMA from Supplier. GEMS-IT or its customer will return the product to Supplier’s
        facility as outlined above .
        Supplier will repair and deliver the product to a location requested by GEMS-IT
        within two (2) weeks of Supplier’s receipt of a returned OEM Product. Supplier
        will bill GEMS-IT at a discount to Supplier’s then current service fee schedule,
        which service fee schedule shall not exceed the amount Supplier charges (after
        discounts) for providing similar services to its own customers. GEMS-IT will
        bill the customer for the service provided. Within the United States and
        Canada,
        out of warranty customer service calls will be handled directly by Cardiac
        Science, and all repaired OEM Products must be delivered within two (2) weeks
        of
        Supplier’s receipt of a returned OEM Product. The parties agree that a list of
        out of warranty services, including prices and the discount rate described
        above, will be added to this Agreement within sixty (60) days of the effective
        date of the third amendment to this Agreement, or such later date as is mutually
        agreed upon by the parties.
 
 Service
        Parts .
        Outside
        the United States and Canada, if Parts and Accessories are required by either
        GEMS-IT or its customers, GEMS-IT will inform Supplier and request direct
        shipment of such Parts and Accessories to GEMS-IT or its customer. Supplier
        will
        bill GEMS-IT at a discount to Supplier’s then current service parts schedule,
        which service parts schedule shall  not
        exceed the amount Supplier charges (after discounts) for providing similar
        parts
        or accessories to its own customers. The parties agree that a list of Parts
        and
        Accessories, including prices and the discount rate described above, will
        be
        added to this Agreement within sixty (60) days of the effective date of the
        third amendment to this Agreement, or such later date as is mutually agreed
        upon
        by the parties. Within the United States and Canada, if Service Parts are
        requested by a GEMS-IT customer, Supplier may sell such Service Parts directly
        to such customer.
 
 Confidentiality
        of Customer Information .
        Supplier agrees that any
        customer-related information obtained by Supplier as a result of its interaction
        with a GEMS-IT customer will be deemed to be GEMS-IT’s “Confidential
        Information”, and will not be used by Supplier for any commercial reason other
        than to fulfill its obligations under this Agreement. For clarity, this
        provision shall not prohibit or restrict Supplier in any way from doing business
        with, soliciting, transmitting information to, or otherwise soliciting entities
        or organizations that happen to be GEMS-IT customers provided that Supplier
        has
        not obtained the names, addresses and contact information for such entities
        or
        organizations by reviewing the GEMS-IT Confidential Information.
 
 Quality
        Reports .
        Supplier will provide, on a monthly basis, a quality assurance report, which
        will include a listing of all product related corrective and preventative
        action
        reports (CAPAs) issued globally for OEM Products or equivalent CSI-branded
        devices, and a detailed description of the root cause analysis of the reason
        for
        the report; notwithstanding the foregoing, Supplier does not need to provide
        any
        information concerning Powerheart AED G3 automatic or FirstSave AED G3 or
        any
        other Cardiac Science products that GEMS-IT does not market. Upon request,
        Supplier will provide GEMS-IT with additional information on any item that
        appears in the quality assurance report and participate in phone calls with
        GEMS-IT regarding the same. Supplier
        will provide, on a monthly basis, a report listing all RMAs issued globally
        for
        OEM Products that have been sold directly or indirectly by GEMS-IT, and a
        detailed description of the root cause analysis of the reason for the return.
        Supplier shall promptly respond to GEMS-IT’s inquiries regarding RMAs if they
        involve GEMS-IT’s customers and the resolution of such RMAs. ”
