8.1.1 Product:




IBM warrants all Products will, be free from defects in material and workmanship. If Customer claims that any Product does not conform to this warranty, Customer must notify IBM of such nonconformities within [*] months from the date IBM shipped the Products. IBM does not warrant: (a) uninterrupted or error free operation of the Products; or (b) that IBM will correct all defects.




8.1.2 Risk Product:

1.0           Term




The term of this Attachment expires on December 31, 2014.




2.0           Scope of Work




2.1           IBM will perform ASIC physical design layout services and manufacture the ASIC Product(s) identified in Part A of this Attachment.




2.2           Customer will provide IBM with the Customer’s Items and cooperate with IBM to enable IBM to manufacture Product and to perform Services in accordance with this Agreement.

3.1.3        Customer’s signature on the RTM shall record Customer’s acknowledgment of satisfactory completion of all work on such Product through the RTM Milestone. To the extent that the RTM varies from the RTL, the RTM shall govern.




3.1.4        Customer’s signature on the RTL and RTM checklists shall not be unreasonably withheld.




3.2           Any data relating to a Product design that Customer is to furnish to IBM must be compatible with IBM design tools, with which IBM will verify all design and engineering work.




3.3           Any cores provided by IBM that are included in the Product design and any IBM design kits will be licensed to Customer pursuant to IBM’s software license agreements. Cores and IBM Design Kits will only be released to Customer upon Customer’s acceptance of such terms and conditions.




4.0            Change Control




4.1           Any changes to the Services or Product design requested by Customer (e.g., netlist slips, additional netlists above standard IBM ASIC Design Methodology, need for more than one IDR, and/or Engineering Change Orders (“ECOs”)) may impact IBM’s schedules and may also result in additional NRE charges and/or an increase in price for Products, Risk Products, and Prototypes. ECOs are defined as Customer initiated functional changes that add, delete, reconnect, or change logic in the existing design. The extent (size of change) and timing of the ECO determines how it is handled by IBM. These changes to the Services or Product will be managed between Customer and IBM using IBM’s ECO/Netlist Change Form. Should IBM submit an ECO/Netlist Change Form to Customer setting forth the probable effect of such requested change on schedule, Customer will be requested to analyze the ECO and sign the ECO/Netlist Change Form where indicated to acknowledge its agreement with the changes. IBM reserves the right to stop work until agreement is reached by the parties with respect to such change. IBM will require a purchase order from Customer for all additional NRE Services resulting from the change before IBM will start work. IBM shall not proceed with any change until authorized in writing by Customer. The parties shall promptly amend this Attachment to incorporate any agreed changes.




4.2           IBM may implement engineering changes to Products. IBM shall give prior notice of engineering changes affecting the form, fit or function of a Product to Customer, provided that Customer has and maintains access to the tool used by IBM to notify customers of engineering changes electronically and provided that Customer has purchased such Product within the two-year period preceding the engineering change.




5.0             End of Life




In the event IBM decides to discontinue manufacturing a Product under this Attachment, IBM will provide Customer with at least twelve (12) months prior written notice of the date that Customer’s non-cancellable last time purchase orders for such Products must be submitted to IBM (“Last Date for Purchase Orders”), provided that Customer has purchased such Product within the two-year period preceding the date upon which notice is to be given. Customer must be willing to take delivery of all such Product within six (6) months of the Last Date for Purchase Orders. All such orders will be completed and filled by IBM in the ordinary course of business and in accordance with the terms of this Agreement. For the period starting in Year 2012 through 2014, IBM may only provide a discontinuance notice for the Product in the event that Customer has failed to purchase at least $[*]  of this Product in Year 2011, and [*]$/year for Years 2012 and 2013.
