4.0  MATERIAL PROCUREMENT

4.1  Solectron is authorized to purchase materials using standard purchasing
     practices including, but not limited to, acquisition of material
     recognizing Economic Order Quantities, ABC buy policy and long lead time
     component management in order to meet the Purchase Order  requirements of
     DMC.  DMC recognizes its financial responsibility and assumes liability for
     long lead items beyond the purchase order coverage. The long lead time item
     list (attached as Addendum "A") will be reviewed quarterly as provided in
     Section 6.2 of this Agreement.

4.2  Solectron agrees to purchase components according to the DMC approved
     vendor list ("AVL") including any sourcing plans as provided by the
     addenda.
     
4.3  In the event of a termination or a cancellation of a Purchase Order or

6.0  PURCHASE ORDERS AND PRICE REVIEWS

6.1  DMC agrees to provide Solectron Purchase Orders or Material Releases [*]
     ([*]) days in advance of delivery (or as otherwise provided by an addendum)
     and shall become effective upon acceptance of the order by Solectron within
     [*] ([*]) days of receipt of said Purchase Order. Financial liability for
     DMC will be limited to material that covers the [*] day released purchase
     order, plus the long lead time material as listed in addendum A, as well as
     non-cancelable and non-returnable material and component supplier minimum
     buy material as provided in Addendum D.

6.2  Solectron and DMC will meet every twelve (12) months during the term of
     this Agreement to review pricing and determine whether any price increase
     or decrease is required. Any price change shall apply only to purchase
     orders or material releases issued after the effective date of such price
     change per Addendum "B", assembly price list.

6.3  Material Fluctuations. If significant price fluctuations occur at any time
     in the cost of material required under this Agreement, DMC and Solectron
     will review the impact of such fluctuations and discuss in good faith
     whether any pricing change should be considered. Significant fluctuation
     means a price change of plus or minus (+/-) [*] percent ([*]%) or more of
     the quoted Bill of Material ("BOM") cost of any Product.

6.4  Currency Fluctuations. If the currency rate of exchange between United
     States Dollars and the currency used for purchase of Products or components
     changes significantly DMC and Solectron agree to share equally the effects
     of such change. Significant change means a currency rate of exchange
     fluctuation of plus or minus (+/-) more than [*] percent ([*]%) of the
     quoted BOM cost of any Product.

     The currency exchange rate will be determined by using The Wall Street
     Journal as the source of reference.  The initial baseline exchange rate
     will be the rate on the effective date of this agreement.   The exchange
     rate will be reviewed and reset on the fifteenth day of the last month of
     every calendar quarter, by taking the average of the previous three (3)
     month exchange rate and using that average as the baseline for the upcoming
     quarter.   This process will be used for all currencies by which components
     are purchased, relative to the U.S. dollar.
     
     If the rate of exchange between U.S. Dollars and the currency used for
     purchase of components fluctuates plus or minus (+/-) [*] percent ([*]%) of
     the selling price or less during a calendar quarter, the agreement upon
     pricing will remain unchanged for products shipped during that quarter.

     If the currency exchange fluctuation exceeds +/- [*] percent ([*]%) of the
     selling price of a Product during a quarter, Solectron and DMC agree to
     share equally any fluctuation in excess of [*] percent ([*]%) baseline. The
     product pricing will be effective immediately and the baseline will be
     reset at the new level and be effective for the remainder of the calendar
     quarter. 
     
6.5  All Purchase orders issued by DMC shall contain the following:

     a)   DMC's part number, description, and revision level of Products to be
          shipped.

     addendum to reflect specific Product requirements.

7.2  All shipments to DMC shall be FOB Solectron's facility.

7.3  Solectron and DMC agree to delivery schedule flexibility requirements
     specific to the Product as documented in Addendum "C".

7.4  Upon learning of any potential delivery delays, Solectron will use its best
     efforts to notify DMC within [*] ([*]) hours as to the cause and extent of
     such delays. Solectron will also, at the time of notification, provide a
     plan of recovery which will bring delivery back to the scheduled plan.

7.5  DMC will make best efforts to reschedule out [*] only any delivery that is
     outside of the [*] ([*]) day window to a maximum of [*] ([*]) days from the
     original delivery date. DMC will not be able to reschedule out within the
     [*] ([*]) day window. If there is no future demand for any rescheduled
     delivery, DMC will purchase all associated components and all assembled
     Product through work in process from Solectron within [*] ([*]) business
     days after receipt of material disposition per Section 4.4 of this
     Agreement.

7.6  Should DMC require Solectron to undertake export activity on behalf of DMC,

     have been received in full, Solectron retains and DMC grants to Solectron a
     security interest in the products delivered to DMC and any proceeds
     therefrom. 


9.0  QUALITY

9.1  Solectron shall manufacture the Products in accordance with the quality 
requirements, standards and expectations as mutually agreed to and reflected 
in the DMC Quality Plan (CQ-QP001) and Solectron CSI Expectations.

10.0 ENGINEERING CHANGES

10.1 DMC may, upon advance written notice to Solectron, submit engineering
     changes for incorporation into the Product.  It is important that this
     notification include documentation of the change to effectively support an
     investigation of the impact of the engineering change.  Solectron will make
     a reasonable effort to review the engineering change and report to DMC
     within one (1) week.  If the engineering change concerns a Product which is
     currently in production by Solectron , Solectron will review the change and
     report back to DMC within one (1) business day.  If any such change affects
     the price, delivery, or quality performance of said Product, an equitable
     adjustment will be negotiated between Solectron and DMC prior to
     implementation of the change.
