SANMINA CORPORATION,
                     EVANS & SUTHERLAND COMPUTER CORPORATION
                              MASTER AGREEMENT FOR
                        ELECTRONIC MANUFACTURING SERVICES


This Master Agreement for Electronic Manufacturing Services (the "Agreement") is
made and entered  into  effective  as of June 3, 1999,  by and  between  Sanmina
Corporation,  a Delaware corporation ("Sanmina") and Evans & Sutherland Computer
Corporation, a Utah Corporation ("Customer" or "E&S").

                                    RECITALS

Sanmina and E&S have entered into an Asset Purchase Agreement dated concurrently
with the date of this Agreement (the  "Purchase  Agreement"),  pursuant to which
Sanmina is acquiring  certain assets  associated  with E&S' Salt Lake City, Utah
prototype,  printed circuit board and other electronic assemblies  manufacturing
operation (the "Electronics  Manufacturing  Operation").  In connection with the
execution  and  performance  of the Purchase  Agreement,  and as a condition and
inducement  to the  parties'  undertakings  therein,  this  Agreement  is  being
executed  to provide  for a  continuing  relationship  between  Sanmina and E&S,
pursuant to which Sanmina will perform manufacturing  services for E&S, upon the
terms and conditions set forth herein.

                                    AGREEMENT

I.       Manufacturing Services to be Performed

     A.   Products.  The products  covered by this Agreement  (collectively  the
          "Products") are those  electronic  products and assemblies,  including
          printed  circuit  boards,  prototypes and Legacy  Products (as defined
          below)  which  Customer  may desire to have  Sanmina  manufacture  for
          Customer  during the term of this Agreement.  "Legacy  Products" means
          those   electronics   products,   boards  and  assemblies   having  no
          identifiable,  forecastable  demand  (i.e.,  driven solely by discreet
          orders)   which   were   previously   produced   at  the   Electronics
          Manufacturing  Operation,  for which Customer may need replacements or
          additional inventory.

     B.   Manufacturing  Services.  During  the term of this  Agreement,  and in
          accordance with the provisions  hereof,  Sanmina will  manufacture and
          sell Products to Customer.

     C.   Scope  of  Agreement.  All  manufacturing  and  sales of  Products  by
          Sanmina,  its  subsidiaries  and  affiliates   (collectively  referred
          hereinafter as "Sanmina") for and to Customer  during the term of this
          Agreement shall be governed by and subject to the terms and conditions
          of this Agreement.

II.       Orders and Acceptances for Products

     A.   Purchase Orders and  Acceptances.  Customer will purchase  Products by
          issuing purchase orders ("Order" or "Orders") to Sanmina.  Orders will
          contain such things as quantity,  prices,  specified  delivery  dates,
          specifications, and Product number or designation, consistent with the
          terms of this  Agreement.  Repeat Orders for Products may initially be
          placed by  electronic  transmission,  provided that Customer will make
          commercially reasonable efforts to send a confirmational written Order
          to Sanmina  (except  as  otherwise  agreed)  within one week after the
          electronic  order.  Blanket  Orders  may be  placed,  with  subsequent
          electronic or written  instructions to authorize shipment and delivery
          of  Products,  up to the  maximum  quantities  covered by the  blanket
          Orders.  Sanmina  will sign and return  written  confirmation  of each
          Order  within  five  business  days  after  receipt.  All  Orders  and
          acceptances relating to Products will be governed by the terms of this
          Agreement,  and nothing  contained in any Order or acceptance  will in
          any way  modify  the terms or  conditions  of this  Agreement,  unless
          expressly  agreed to in writing by Sanmina and  Customer.  Sanmina and
          Customer  hereby give notice of their  objection to any  additional or
          different terms.

     B.   Placement of Orders;  Delivery of  Forecasts.  Upon  execution of this
          Agreement, Customer will submit an Order for Products deliverable over
          the  first  three  months of the term of this  Agreement.  Thereafter,
          Customer will provide Orders to Sanmina on a monthly basis,  including
          orders for Products to be delivered in the third month  following  the
          date of the Order,  resulting in a rolling three month period  covered
          by Orders.  Upon execution of this  Agreement,  and on a monthly basis
          thereafter,  concurrently  with the  submission of the monthly  Orders
          referenced above,  Customer will provide a rolling nine month forecast
          of Customer's anticipated Product purchases, for the nine month period
          immediately  following  the three month  period  covered by  submitted
          Orders.  Obligations  to purchase  Products,  and any liability of the
          parties with respect to anticipated Product  requirements,  will arise
          only as  actual  Orders  are  submitted  to  Sanmina,  with  the  sole
          exception  that with respect to any long  lead-time  parts for which a
          forecast would cause procurement activity as provided herein, Customer
          shall have those  obligations  set forth in Section III below.  Actual
          Orders  may  be  different  from  forecasted  numbers.  Orders  may be
          submitted  other  than  at  the  monthly  intervals   provided  above,
          consistent  with  the  terms  of this  Agreement.  Where  appropriate,
          Customer will level load requirements for certain Products in order to
          provide a steady flow of Product to Customer  and a steady  production
          schedule  for  Sanmina.  Sanmina  will  review  forecasts  provided by
          Customer and advise  Customer if Sanmina  anticipates  that it will be
          unable to achieve the Product volumes reflected in such forecasts.

     C.   Acceptance  of Orders.  Sanmina  will  accept all orders for  Products
          submitted by Customer in accordance  with the terms and  conditions of
          this  Agreement up to the greater of (i) 125% of the amount  specified
          in the forecast  delivered in the preceding  month with respect to the
          period  covered by such  Orders,  or (ii) the amount of  Products  for
          which Sanmina has purchased  Materials,  as provided  herein.  Sanmina
          will use its  reasonable  best efforts to accept  Orders  submitted by
          Customer for Products in excess of the committed volume levels. Orders
          submitted in excess of the committed  quantity  levels that Sanmina is
          unable to accept must be  rejected  within  five  business  days after
          receipt by Sanmina.

III.      Materials Planning, Procurement Process and Liabilities

     A.   Master Production Schedule. Based on the Orders and forecasts received
          from  Customer  as provided  above,  Sanmina  will on a monthly  basis
          generate a Master  Production  Schedule  ("MPS") for a rolling  twelve
          month  period.  This MPS will define the master plan on which  Sanmina
          will  base  its  procurement,   internal   capacity   projections  and
          commitments.  The MPS created as  described  above will not impose any
          liability on either  Sanmina or Customer,  except that with respect to
          any long  lead-time  parts and that portion of the MPS related to firm
          orders as described in Section II  paragraph B of this  document,  for
          which the MPS would cause  procurement  activity  as provided  herein,
          Customer shall have those obligations set forth in this Section III.

     B.   Material  Procurement  Schedule.  Sanmina will process the MPS through
          industry-standard  MRP software  that will convert the MPS  reflecting
          Customer's  Orders and  forecasts  into  requirements  for  components
          utilized to make the  applicable  Products.  In doing so, Sanmina will
          off-set the  requirements  for receipt of  components  or materials by
          allowing for the time required to build the Products per the following
          times:

         1.       In-Circuit Test/Functional Test - 5 Working Days
         2.       Assembly - 7 Working Days
         3.       Kitting - 2 Working Days
         4.       Material Handling - 2 Working Days

          Per this Agreement,  Sanmina will plan and schedule  material to be at
          Sanmina  eleven  working  days before the  Products are due to ship to
          Customer  where no test is required,  and sixteen  working days before
          the Products are due to ship to Customer where testing is required.

     C.   Sanmina Orders for Materials.  Sanmina will release (launch) orders to
          suppliers of materials  required in connection  with the production of
          Products a  reasonable  period of time prior to the  anticipated  date
          that the material is needed (as set forth in the preceding paragraph).
          When these  orders are  launched  will  depend on the vendor lead time
          determined by Sanmina from time to time and  maintained as a parameter
          of Sanmina's  manufacturing or materials  planning  systems.  Sanmina,
          through its MRP system,  will also issue an instruction ("MRP signal")
          to its procurement group to buy a part approximately seven days before
          the  order is due to be  placed in  accordance  with  this  paragraph.
          Unless   otherwise   directed  by  Customer,   Sanmina  will  purchase
          components  for Products in accordance  with a vendor list approved by
          Sanmina  and  Customer  ("AVL").  In the event  Sanmina for any reason
          cannot  purchase any components  from an approved  vendor named on the
          AVL,  Sanmina may purchase such  components  from an alternate  vendor
          with the prior written consent of Customer.  In no event will Sanmina,
          without  the prior  written  consent of  Customer,  be  authorized  to
          purchase  (or to impose  obligations  on  Customer  with  respect  to,
          pursuant  to  Section  III of this  Agreement),  materials,  parts and
          components beyond those necessary to support Orders actually delivered
          by  Customer,  with the  exception  of minimum  quantity  requirements
          imposed by vendors for parts being  procured by Sanmina for  Customer,
          and any anticipated Orders for the next 30 day period, as reflected in
          any  forecasts  delivered  by  Customer  to  Sanmina.  Proto-type  and
          Quick-turn Orders will not appear on the MPS, but will be managed on a
          manual  basis due to the  critical  time  factor and lot size of these
          orders.  Customer  agrees  that it will be liable for all  materials ,
          including minimum purchase requirements,  purchased for any Quick-turn
          or Proto-Type Order that Customer places with Sanmina.

     D.   Materials  Classifications  and Periods of Supply. When Sanmina places
          an  order  with  its  suppliers  in  accordance   with  the  preceding
          paragraph,  Sanmina will order parts in various quantities (defined in
          periods-worth-of-supply)   that  are   defined   by  the   part's  ABC
          classification.   This   classification,   as  well  as  the  expected
          distribution or  characteristics  of various classes of parts, and the
          periods-worth-of-supply  ("Periods-of-Supply") that will be bought for
          each class of part, are shown on the following table:



                         ABC Classifications, Descriptions and Periods-of-Supply
- --------------------------- -------------------------- -------------------------- --------------------------
        Part Class                  Expected                   Expected               Periods Worth of
                               Percentage of Total        Percentage of Total        Supply to be Bought
                                      Parts                 Value (of Gross            With Each Order
                                                             Requirements)

                                                                                  
            A                          3%                         80%                      4 Weeks
- --------------------------- -------------------------- -------------------------- --------------------------
            B                          17%                        17%                     3 Months
- --------------------------- -------------------------- -------------------------- --------------------------
            C                          80%                        3%                      12 Months
- --------------------------- -------------------------- -------------------------- --------------------------


     E.   Materials  Quantities  Criteria.  In addition  to  ordering  parts for
          various  Periods-of-Supply  as  referenced  above,  Sanmina will order
          parts according to appropriate minimum-buy  quantities,  tape and reel
          quantities, and multiples of packaging quantities.

     F.   Customer  Liability for Materials.  In the event that Sanmina procures
          (other  than  pursuant  to  the  terms  of  the  Purchase   Agreement)
          components, parts or materials unique to, and specifically for use in,
          Products ordered or forecasted by Customer (collectively "Materials"),
          consistent  with the procurement  procedures set forth above,  and any
          such  Materials  become  obsolete or surplus to Customer,  so as to be
          unusable in current  Orders for Products from  Customer,  then Sanmina
          will provide to Customer  prompt notice of such  obsolescence/surplus,
          and the  potential  cost to  Customer  hereunder  as a result  of such
          obsolescence or surplus. Sanmina shall use its reasonable best efforts
          (for a period of at least four weeks) to cancel any outstanding orders
          for any such  Materials,  use  excess/uncancelable  Materials  for the
          manufacture of products for other customers, and return such Materials
          back to the original  supplier or sell such  Materials to the original
          supplier or a third party at the original  purchase  price, or on such
          other  terms as  Supplier  and  Customer  may  agree  upon.  After the
          exhaustion of such remedies,  Sanmina will be entitled to: (a) sell to
          Customer any  remaining  obsolescent/surplus  Materials,  at an amount
          equal  to  116%  of  Sanmina's   out-of-pocket   costs  therefor  (the
          "Materials  Transfer  Price");  and (b) invoice  Customer  for (i) the
          amount by which the Materials  Transfer  Price for any such  Materials
          which  Sanmina  was able to sell to third  parties as  provided  above
          exceeded  the price  obtained  from such third  parties  with  respect
          thereto,  and (ii) the amount of any re-stocking or other fees charged
          to Sanmina  with  respect to any order  cancellations  and  returns of
          obsolete/surplus  Materials.  Customer's  obligations  with respect to
          obsolete/surplus Materials as set forth herein shall not extend to any
          materials  acquired by Sanmina  pursuant to the terms of the  Purchase
          Agreement.  Customer's only obligations with respect to such Materials
          shall be as set forth in the Purchase Agreement.

     G.   Acquisition of Tooling.  If necessary and with the Customer's  written
          consent,  Sanmina  will  acquire  any  necessary  tools and tooling to
          fulfill any Orders.  All such tooling required by Sanmina shall remain
          the Customer's property, and Sanmina shall return such tooling (normal
          wear and tear  excepted)  to  Customer  upon  request,  following  the
          completion of the relevant Order or the termination of this Agreement.
          Responsibility  for the cost of tooling acquired pursuant to the terms
          of the  Purchase  Agreement  shall  be as set  forth  in the  Purchase
          Agreement.  Except  as  otherwise  provided  herein  or  agreed by the
          parties hereto, Customer will be responsible for the cost of all other
          tools and tooling required to be acquired by Sanmina  hereunder.  When
          requested  by  Customer,  and  agreed to in  writing  by  Sanmina  and
          Customer,  the  cost  of  such  tooling  will be  amortized  over  the
          estimated volume of Products to be produced with such tooling.

     H.   Limitations on Sanmina's Rights to Build Ahead.  Although Orders cover
          up to 90 days and  forecasts  cover  longer  periods,  Sanmina  is not
          authorized to make  unilateral  decisions on the amount of Products to
          be built more than 30 days prior to scheduled  delivery date, with the
          exception  of agreed upon  Kanban  levels.  Lot sizes and  build-ahead
          quantities  will be the result of a mutual  agreement  between Sanmina
          and Customer.

IV.       Reschedules

     A.   Rescheduling  Matrix.  Customer  may  reschedule  delivery  dates  for
          Products subject to the following matrix:

                   Notice Prior to                    Percent of Original
                      Original                       Quantity that can be
                    Delivery Date                          Rescheduled

                    0 to 30 days                               0%
                    31 to 60 days                             25%
                    61 to 90 days                             50%
                   Beyond 90 days                            100%

          As an example,  if Customer notifies Sanmina in writing between 31 and
          60 days  prior to the  scheduled  deliver  date of  certain  Products,
          Customer may  reschedule the delivery of a maximum of 25% of the total
          amount of such Products.

     B.   Revised Delivery Dates. Deliveries rescheduled as provided above shall
          be  deferred  to such date or  dates,  within  60 days  following  the
          original delivery date, as Customer may reasonably determine. A change
          in the delivery date of any Product for a period  exceeding 60 days in
          the aggregate  shall be deemed a cancellation by Customer with respect
          to such Product.

V.        Revisions

          In the event  Customer  requests an  engineering  change to a Product,
          Sanmina  will  notify  Customer  of  any  impact  on the  cost  and/or
          scheduled  delivery of such Product  within five  business days of the
          receipt of Customer's request. Unless Customer consents to the amended
          notification from Sanmina,  the requested  engineering  change will be
          deemed  canceled.  Any  changes  (whether  up or  down) in the cost of
          Products  resulting from an  engineering  change order ("ECO") will be
          applied to the applicable  purchase  price for such Products.  Sanmina
          will charge a $250.00  administrative  fee per ECO to partially  cover
          Sanmina's processing costs involved in processing the ECO.

VI.       Cancellations

          Customer may cancel any Order,  with the exception of  Quick-turn  and
          /or  Proto-type  Orders,  by notifying  Sanmina in writing at least 30
          days prior to the delivery date of such Order.  Within 10 days of such
          cancellation,  Sanmina  will  provide  Customer  with  the  amount  of
          Customer's  obligations  with  respect to  Materials  and labor  costs
          associated  with the canceled order, as provided in Section III above.
          Customer will pay such cancellation  amount to Sanmina on a net 30 day
          basis.  After  receipt  of such  cancellation  amount,  Sanmina  shall
          deliver to Customer,  at Customer's  expense,  any Materials purchased
          but unused as a result of such  cancellation  or scrap such Materials,
          at the discretion of Customer.

VII.      Product Pricing

     A.   Initial Prices; Adjustments. The initial prices for Products listed in
          Exhibit  A  attached  hereto  will be as set forth in  Exhibit  A. For
          Products  not  listed  in  Exhibit  A, or with no  prices  established
          therefor, the prices shall be established through the Sanmina-Customer
          quote process.  Sanmina will respond to Customer's requests for quotes
          and proposals  within 14 days after receipt of all necessary data. The
          initial  prices for Products shown in Exhibit A will be evaluated on a
          quarterly  basis for  potential  changes,  in  accordance  with  prior
          agreements   with   Customer.   Customer   expects   improvements   in
          efficiencies,  material cost  reductions and  innovative  processes to
          contribute  to  these  reductions.  Prices  otherwise  established  as
          provided  herein  are  subject to  adjustment  as  provided  herein to
          reflect ECOs and  variations  in the market  prices of  Materials  and
          other  components.  Any cost  reductions  realized by Sanmina due to a
          reduction  in material or labor  costs or yield  improvements  will be
          shared equally with Customer at the time such reductions are realized.
          Any price  decreases  will apply  immediately  to all new Orders Price
          increases  will apply to new Orders issued (i) after  agreement by the
          parties  of the price  increase,  or (ii) more than  thirty  (30) days
          following Customer's receipt of written notice of the increase.

     B.   Computation  of  Prices;  Taxes.  All  prices of  Products  are F.O.B.
          Sanmina's  facility.  All  prices  will  be  quoted  and  paid in U.S.
          dollars.  All prices applicable to Products  purchased pursuant to the
          terms of this  Agreement  will  include  all  charges  for  packaging,
          packing,  crating,  storage and shipping and  transportation  costs to
          Customer's  facility or other designated  ship-to location,  except as
          otherwise provided herein. Prices do not include any federal, state or
          local sales, use, excise VAT and similar taxes, that may be applicable
          to the Products. When Sanmina has the obligation to collect taxes, the
          appropriate amount may be added to Customer's invoice and will be paid
          by  Customer  unless  Customer  provides  Sanmina  with  a  valid  tax
          exemption  certificate  authorized by the appropriate taxing authority
          and quantities.

     C.   Most Favored Customer  Pricing.  In no event are the prices applicable
          to Products ordered by Customer hereunder to be higher than the lowest
          prices  then  offered by Sanmina to its most  favored  customers,  for
          substantially similar products and quantities.

VIII.     Shipping and Delivery

     A.   Delivery  Terms.  Customer's  Orders  will  state  delivery  dates for
          Products in accordance with the terms of this Agreement, and time will
          be of the essence in meeting Customer's delivery requirements.  Unless
          otherwise  agreed in writing by the parties,  delivery of all Products
          under this Agreement  shall be F.O.B.  Sanmina's  plant, at which time
          risk of loss and title shall pass to Customer.

     B.   Shipping.  Sanmina will transport  Products by the method specified by
          Customer,  to Customer's address or to an address specified in writing
          by Customer.  All freight,  insurance and other shipping expenses from
          the delivery point shall be borne by Customer.  All Products delivered
          pursuant to the terms of this  Agreement  will be suitably  packed for
          shipment in a  commercially  reasonable  manner in Sanmina's  standard
          shipping  cartons,  unless  otherwise  designated  by  Customer.  When
          special  packaging  is  requested  or, in the opinion of  Sanmina,  is
          required under the circumstances,  the additional  expenses related to
          such  special  packaging  will be borne  by  Customer.  Each  shipping
          container  will be marked to show  Customer's  Order  number,  Product
          description and identifying  numbers,  and quantity contained therein.
          If  Products  are  delivered  more than five  days in  advance  of the
          specified  delivery date,  Customer may either return such Products at
          Sanmina's  risk and expense for  subsequent  delivery on the specified
          delivery  date or retain such  Products and make payment when it would
          have been due based on the  specified  delivery  date. If Products are
          returned to Sanmina then reshipped to Customer,  Sanmina will bear the
          cost and risk of loss associated  with such return and reshipment.  In
          the event  Products  will be delivered  more than five  business  days
          late,  Customer may request such  Products to be shipped and delivered
          via an expedited method of delivery.  In such event, Sanmina agrees to
          pay or reimburse Customer for all transportation  charges in excess of
          the normal charges.

IX.       Payment and Invoicing

          Payment terms will be net 30 days from invoice date,  which will be no
          earlier than the date of delivery to Customer of the Products  covered
          thereby.  Sanmina will provide  Customer with a credit limit].  In the
          event that  Customer  exceeds  this  credit  limit or has  outstanding
          invoices for more than 60 days, Sanmina may stop shipments of Products
          to  Customer  until  Customer  makes  sufficient  payment to bring its
          account  consistent  with  terms  outlined  above.  In the  event of a
          material  default by Customer of its  payment  obligations  hereunder,
          Sanmina may reduce the credit limit, upon written notice to Customer.

X.        Quality Standards and Warranty

          Sanmina  warrants that the Products will be manufactured in a good and
          workmanlike  manner,  consistent  with  industry  standards,  and will
          conform to and perform in accordance with  applicable  specifications,
          and that the Products (excluding components purchased from third-party
          vendors  ("Vendor  Components"))  will be free  from  any  defects  in
          workmanship  for a period  of one year  from the date of  delivery  to
          Customer.  Warranty on Vendor  Components  is limited to the  warranty
          provided  by the  component  manufacturer.  Sanmina  will  pass on any
          unexpired warranty for such Vendor Components  provided by third-party
          vendors or passed on by such  third-party  vendors  from the  original
          manufacturers  until the expiration of such warranties.  As Customer's
          sole remedy under the warranty,  Sanmina  will, at no charge,  rework,
          repair and retest,  or replace,  any Products  returned to Sanmina and
          found  not  to be  manufactured  in  accordance  with  the  applicable
          specifications or that are otherwise defective. Warranty coverage does
          not include failures due to Customer's design, the supply or selection
          of improper or defective  parts or materials  designated  by Customer,
          Customer  requested  changes,  damages  caused by Customer's  misuses,
          unauthorized  repair  or  negligence.  Sanmina  does  not  assume  any
          liability  for  expendable   items  such  as  lamps  and  fuses.   The
          performance  of any repair or  replacement  by Sanmina does not extend
          the warranty period for any Products  beyond the period  applicable to
          the Products originally delivered.

          EXCEPT  FOR  THE  ABOVE  EXPRESS  WARRANTIES,  SANMINA  MAKES  AND THE
          CUSTOMER  RECEIVES NO WARRANTIES ON THE  PRODUCTS,  EXPRESS,  IMPLIED,
          STATUTORY,  OR  OTHERWISE,  AND  SANMINA  SPECIFICALLY  DISCLAIMS  ANY
          IMPLIED  WARRANTY  OF  MERCHANTABILITY  OR  FITNESS  FOR A  PARTICULAR
          PURPOSE.

XI.       Service of Legacy Products

          During  the  term  of  this   Agreement,   Sanmina  will  continue  to
          manufacture and repair all Legacy Products as Customer may request, in
          accordance  with such pricing  schedule as may be mutually agreed upon
          by the parties from time to time, consistent with the Sanmina-Customer
          quote process referenced in Section VII above.

XII.     Design Services

          During  the  term of  this  Agreement,  Sanmina  will  provide  design
          services to Customer, in connection with the design and development of
          prototype and production  electronic  circuit  boards,  assemblies and
          Products,  at such prices and on such terms as may be mutually  agreed
          upon  by  the  parties  from  time  to  time,   consistent   with  the
          Sanmina-Customer quote process referenced in Section VII above.


XIII.    Minimum Work Commitment - "Take or Pay" Provision

     A.   Minimum Order  Requirement.  During each of the three one year periods
          commencing  from the effective date of this  Agreement,  Customer will
          undertake to submit to Sanmina Orders for Products and design services
          having an aggregate purchase price of at least $22,000,000 (subject to
          adjustment  as  provided  below).  If in any of such one year  periods
          Customer  should  fail to submit  Orders to  Sanmina  in such  minimum
          aggregate  amount,  then  Customer  will make  payments  to Sanmina as
          provided below (and such payment  obligations  will be Customer's sole
          liability and Sanmina's sole remedy with respect to any such failure).

     B.   Consequence  of Missing First or Second Year Targets by More Than 20%.
          If,  during the first or second one year  period  commencing  from the
          effective date of this  Agreement,  Orders are submitted to Sanmina in
          an aggregate  amount of less than 80% of the targeted  minimum  amount
          (or $17,600,000 in the first year),  then within 60 days following the
          end of such one year period,  Customer will pay to Sanmina a sum equal
          to the  amount  of such  shortfall,  multiplied  by 25%  (representing
          Sanmina's assumed profit margin with respect to the Orders represented
          by the  shortfall).  For  example,  if during the first year  Customer
          submitted Orders to Sanmina  aggregating  $15,000,000,  Customer would
          pay to Sanmina the sum of $7,000,000 x .25 = $1,750,000.

     C.   Consequence  of Missing First or Second Year Targets by Less Than 20%.
          If,  during the first or second one year periods  commencing  from the
          effective date of this  Agreement,  Orders are submitted to Sanmina in
          an aggregate  amount of at least 80% of the targeted  minimum  amount,
          then  the  amount  of the  shortfall  will  be  added  to the  minimum
          commitment applicable to the following year, and any amount to be paid
          by Customer to Sanmina  would be  determined  after  completion of the
          following  year.  For  example,  if  during  the first  year  Customer
          submitted Orders to Sanmina aggregating $20,000,000,  then the minimum
          order requirement applicable to the second year would be $24,000,000.

     D.   Consequence  of Missing  Third Year Target.  If,  during the third one
          year period  commencing  from the  effective  date of this  Agreement,
          Orders are  submitted to Sanmina in an  aggregate  amount of less than
          the targeted minimum amount,  then within 60 days following the end of
          such one year period,  Customer will pay to Sanmina a sum equal to the
          amount of such shortfall,  multiplied by 25%  (representing  Sanmina's
          assumed  profit margin with respect to the Orders  represented  by the
          shortfall).  For example,  if during the third year Customer submitted
          Orders  to  Sanmina  aggregating  $20,000,000,  and,  as a result of a
          carry-over  of  $2,000,000  from the second  year the  minimum  target
          applicable to the third year were $24,000,000, then Customer would pay
          to Sanmina the sum of $4,000,000 x .25 = $1,000,000.

     E.   Carry-Over  of Orders in Excess of  Minimum.  If,  during the first or
          second one year periods  commencing  from the  effective  date of this
          Agreement,  Orders are submitted to Sanmina in an aggregate  amount in
          excess of that  required to satisfy the minimum  obligation  set forth
          above (i.e., having an aggregate purchase price of $22,000,000 or such
          lesser amount which,  when added to the excess Orders submitted during
          the  prior  year,   would  satisfy  the  minimum  annual   $22,000,000
          requirement), then the amount by which the aggregate purchase price of
          such Orders exceed such targeted minimum amount (the "Surplus Amount")
          will be  counted  toward  satisfaction  of  Customer's  minimum  Order
          requirement for the next one year period.

     F.   Sale of  Operations;  Counting  of Orders.  If, at any time during the
          three year period that the  requirements  of this  Section XIII are in
          effect,   Customer  sells  any  divisions  or  operations  which  have
          previously  submitted  Orders to  Sanmina  hereunder,  then any Orders
          subsequently  submitted  to Sanmina by the  purchaser  with respect to
          products  Sanmina is building for any such division or operation  will
          be counted  toward the  satisfaction  of the  targeted  minimum  Order
          requirement hereunder,  as if such Orders had been submitted hereunder
          by Customer to Sanmina.

XIV.     Right of First Refusal

          As Customer  develops  new  products  that  require  manufacturing  of
          printed circuit boards or other electronics  assemblies or components,
          or puts out to bid the  manufacturing  rights to the  printed  circuit
          boards or other electronics  components of existing products,  then to
          the extent such manufacturing  rights are not contractually  committed
          to any other party,  and Sanmina  demonstrates to the  satisfaction of
          Customer  that  it  can  satisfactorily   perform  such  manufacturing
          operations in terms of price competitiveness,  quality, timeliness and
          production  capacity,  Customer  will  extend to Sanmina  the right to
          perform such manufacturing  services, on such terms as Customer may in
          its discretion determine to be appropriate.

XV.      Testing

          During  the  term  of  this  Agreement,  and in  accordance  with  the
          following requirements,  Sanmina will continue to maintain and support
          all in-circuit  tests  developed for the S790 test  platform,  and E&S
          will  support,  sustain  and develop all  functional  test  platforms,
          diagnostics and post production test hardware:

          1.   System  Requirements.  Sanmina  will  maintain  the S770 and S790
               systems. Sanmina has the option of converting to the S790 system,
               and Sanmina  will  convert all S770  fixtures and programs to the
               S790 as required by Order, thereby eliminating the requirement to
               maintain the S770 system once all S770 fixtures and programs have
               been converted. The conversion will be at E&S expense.

          2.   Fixture Requirements.

               a.   Sanmina  will  preserve  and maintain all S770 and S790 test
                    fixtures in good working order.

               b.   In the event that Customer  requires changes to current test
                    fixtures,   Sanmina  will  provide  services   necessary  to
                    implement  and  maintain  changes.  In the  event  that  the
                    changes  will  require a new test  fixture,  Sanmina has the
                    option to move the test to a  different  platform or system.
                    Any of the above  actions  pursuant to this  paragraph  2(b)
                    will be at the expense of E&S.

          3.   Test Program Requirements. Sanmina will preserve and maintain all
               S790 test  programs  in good  working  order.  In the event  that
               Customer requires changes to current test programs,  Sanmina will
               provide services necessary to implement and maintain changes,  at
               E&S' expense. Prudent test program archival and back-up processes
               will be secured to prevent the loss of any test programs.

          4.   Status of Tools and  Tooling.  All tools and tooling  relating to
               test fixtures and programs  provided to and maintained by Sanmina
               will remain the property of Customer.

XVI.     Indemnification

          A.   By Customer.  Customer will  indemnify and hold harmless  Sanmina
               from and against any and all losses, damages, costs,  liabilities
               or expenses  (including  court costs and the  reasonable  fees of
               attorneys  and  other  professionals)  to the  extent  that  such
               losses,  costs,  liabilities  or  expenses  arise  out of,  or in
               connection  with, in whole or in part, (a)  infringements  of any
               patent,  trademark,  copyright or other intellectual  property of
               Customer or (b) any negligence or willful misconduct by Customer,
               its  employees or agents and  subcontractors,  including  but not
               limited to any such act or omission that  contributes to: (i) any
               bodily injury,  sickness,  disease,  or death; (ii) any injury or
               destruction  to  tangible or  intangible  property of the injured
               party  or any  loss of use  resulting  therefrom;  or  (iii)  any
               violation of any statute, ordinance or regulation.

          B.   By Sanmina.  Sanmina will  indemnify and hold  harmless  Customer
               from and against any and all losses, damages, costs,  liabilities
               and expenses  (including  court costs and the reasonable  fees of
               attorneys  and  other  professionals)  to the  extent  that  such
               losses,  costs,  liabilities  or  expenses  arise  out of,  or in
               connection with, in whole or in part, (a) Sanmina having utilized
               in the  manufacture  of any  Products any  intellectual  property
               rights of  others,  where such use has not been  required  by the
               specifications or instructions provided to Sanmina by Customer or
               (b)  any  negligence  or  willful  misconduct  by  Sanmina,   its
               employees or agents and subcontractors, including but not limited
               to any such act or omission that  contributes  to: (i) any bodily
               injury,   sickness,   disease,  or  death;  (ii)  any  injury  or
               destruction  to  tangible or  intangible  property of the injured
               party  or any  loss of use  resulting  therefrom;  or  (iii)  any
               violation  of any  statute,  ordinance  or  regulation.  .  XVII.
               Quality, Inspection and Reporting

          A.   Inspection  of  Work.   Customer  will  have  the  right  at  all
               reasonable  times,  upon  reasonable  advance  notice,  to  visit
               Sanmina's  plant to  inspect  the  work  performed  on  Products.
               Inspection  of the work shall not  relieve  Sanmina of any of its
               obligations  under this  Agreement  or any Orders.  Sanmina  will
               provide Customer with all mutually agreed upon quality reports at
               agreed upon  intervals.  Sanmina  reserves  the right to restrict
               Customer's access to the plant or any area within it as necessary
               to  protect  confidential  information  of  Sanmina  or its other
               customers.

          B.   Inspection  as  Condition  of  Acceptance.  If  Customer  demands
               inspection of any Products prior to the delivery of such Products
               as a condition of  acceptance  of such  Products,  Customer  must
               inspect the Products within 48 hours of a transmission of written
               notice by facsimile or other  electronic or  telephonic  delivery
               system from  Sanmina  informing  Customer  that the  Products are
               ready to be shipped.

          C.   Quality Improvement Program.  Customer and Sanmina will implement
               a  joint  quality  improvement  program  that  will  develop  and
               implement continuous Product quality improvements.

XVIII.   Term and Termination

          A.   Initial Term; Extension.  This Agreement shall be in effect for a
               period of 36 months  commencing from the effective date hereof as
               set  forth  above,  unless  earlier  terminated  or  extended  as
               provided  herein.  The parties may, by mutual  agreement,  extend
               this   Agreement  at  any  time  prior  to  its   expiration   or
               termination. Except as otherwise specifically provided herein, in
               the  event  of the  expiration  or  earlier  termination  of this
               Agreement,  the  Agreement  shall remain in full force and effect
               with respect to, and shall be applicable to, any Orders issued by
               Customer  and  accepted by Sanmina  prior to such  expiration  or
               termination.

          B.   Termination.  Either party may, without  penalty,  terminate this
               Agreement upon 60 days prior written notice to the other party in
               either one of the following events:

               1.   the other party materially  breaches this Agreement and such
                    breach  remains  uncured  for  thirty  (30)  days  following
                    written notice of breach from the non breaching party; or

               2.   the  other  party  becomes  involved  in  any  voluntary  or
                    involuntary  bankruptcy  or  other  insolvency  petition  or
                    proceeding  for  the  benefit  of its  creditors,  and  such
                    petition,  assignment or proceeding is not dismissed  within
                    sixty (60) days after it was filed.

          C.   Effect of Termination. Upon the expiration or earlier termination
               of this Agreement,  Sanmina will provide Customer with an invoice
               of amounts owed to Sanmina hereunder. In addition,  Customer will
               be liable  for all  work-in-progress  at its value at the time of
               cancellation and any outstanding  charges.  Any  work-in-progress
               and/or  finished  goods  built  beyond the  mutually  agreed-upon
               schedule  will  not  be  the  responsibility  of  Customer.  Upon
               termination, Customer will pay all invoiced charges in net thirty
               (30) days.

XIX.     Limitation of Liability

               party to be charged.  The failure by either  party to enforce any
               rights thereunder will not be construed as a waiver of any rights

               right to assign its rights or  obligations  under this  Agreement
