2.3      Payments made by Buyer to Seller under this Amendment shall be included
         in the "Sourcing/Supplier Quality and Manufacturing" work task category
         in the Statement of Work set forth in the March 17 Agreement.

3.1      The Contract Price shall be paid by Buyer to Seller at the times and in
         the manner set forth in the March 17 Agreement. For purchases made by
         Seller on behalf of Buyer, Buyer shall reimburse Seller within ten days
         of purchase or as mutually agreed by Buyer and Seller.

                              4. Excusable Delays

4.1      Seller shall not have any liability or be considered to be in breach or
         default of its obligations under the Amendment to the extent that
         performance of such obligations is delayed or prevented, directly or
         indirectly, due to: (i) causes beyond its reasonable control; or (ii)
         acts of God, act (or failures to act) of governmental authorities,
         fires, severe weather conditions, earthquakes, strikes or other labor
         disturbances, floods, war (declared or undeclared), epidemics, civil
         unrest, riot, delays in transportation, or car shortages; or (iii) acts
         (or omissions) of Buyer including failure to promptly: (a) provide
         Seller with information and approvals necessary to permit Seller to
         proceed with work immediately and without interruption, (b) comply with
         the terms of payment, or (c) provide Seller with such evidence as
         Seller may request that any export or import license or permit has been
         issued (if such is the responsibility of Buyer), or (iv) inability on
         account of causes beyond the reasonable control of Seller to obtain
         necessary materials, necessary components or services. Seller shall
         notify Buyer of any such delay. The date of delivery or of performance
         shall be extended for a period equal to the time lost by reason of
         delay, plus such additional time as may be reasonably necessary to
         overcome the effect of such excusable delay. Seller shall notify Buyer,
         as soon as practicable, of the Service resumption date. If Seller is
         delayed by acts or omissions of Buyer, or by the prerequisite work of
         Buyer's other contractors or suppliers, Seller shall also be entitled
         to an equitable price adjustment.


                                       3



4.2      If delay excused by this Article extends for more than one hundred and
         twenty (120) days and the parties have not agreed upon a revised basis
         for continuing the work at the end of the delay, including adjustment
         of the price, then either party (except where delay is caused by Buyer,
         in which event only Seller), upon thirty (30) days' written notice, may
         terminate the Amendment with respect to any uncompleted Services,
         whereupon Buyer shall promptly pay Seller's termination charges
         determined in accordance with Seller's standard accounting practices
         upon submission of Seller's invoices therefor.

                  5. Compliance With Laws, Codes And Standards

         Notwithstanding any other provisions herein, Buyer shall be responsible
         for the timely obtaining of any required authorization, such as an
         export license, import license, foreign exchange permit, work permit or
         any other governmental authorization, even though any such
         authorization may be applied for by Seller. Buyer and Seller shall
         provide each other reasonable assistance in obtaining required
         authorizations. Seller shall not be liable if any authorization is
         delayed, denied, revoked, restricted or not renewed and Buyer shall not
         be relieved thereby of its obligations to pay Seller for the work.

                           6. Limitation Of Liability

6.1      The total liability of Seller, on all claims of any kind, whether in
         contract, warranty, indemnity, tort (including negligence), strict
         liability, or otherwise, arising out of the performance or breach of
         the Amendment or use of any equipment shall not exceed the greater of
         US $10,000 or the Contract Price of a fixed price contract or the price
         of work completed for a time and materials or cost plus contract. All
         liability under the Amendment shall terminate upon the expiration of
         the Amendment.

6.2      In no event, whether as a result of breach of contract, warranty, tort
         (including negligence), strict liability, indemnity, or otherwise,
         shall Seller or its subcontractors or suppliers be liable for loss of
         profit or revenues, loss of use of the equipment or any associated
         equipment, cost of capital, cost of substitute equipment, facilities,
         services or replacement power, downtime costs, claims of Buyer's
         customers for such damages, or for any special, consequential,
         incidental, indirect or exemplary damages and Buyer shall indemnify
         Seller against such claims of Buyer's customers.

6.3      If Seller furnishes Buyer with advice or assistance concerning any
         products, systems or work which is not required pursuant to the
         Amendment, the furnishing of such advice or assistance will not subject
         Seller to any liability, whether in contract, indemnity, warranty, tort
         (including negligence), strict liability or otherwise.



                                       4



6.4      For the purposes of this Article 6, the term "Seller" shall mean

         their respective agents and employees, whether individually or
         collectively.


6.5      The provisions of this Article 6 shall prevail over any conflicting or
         inconsistent provisions contained in any of the documents comprising
         the Amendment, except to the extent that such provisions further
         restrict Seller's liability.

                           7. Relationship of Parties

7.1      Seller is an independent contractor under this Amendment, as is each
         affiliate, agent or employee of Seller. Seller acknowledges that,
         except as authorized by Buyer on a case-by-case basis, Seller does not
         have the authority to obligate Buyer in any manner whatsoever.

7.2      Buyer's personnel shall remain employees of and shall be supervised
         solely by Buyer, and shall not be employees of Seller. Buyer shall not
         express or imply to any such personnel that they have any rights as
         employees of Seller and Buyer shall indemnify Seller against any costs,
         damages, and liabilities, including attorney fees that Seller may incur
         as a result of claims, suits, or actions by any such personnel,
         provided that such claims, suits, or actions not result from willful
         actions or inactions of Seller.

7.3      Each party and its employees shall comply with all rules, including
         safety, traffic and security, established by the other party for
         operations within the other party's location(s).

                     8. Expiration - Renewal - Termination


8.1      This Amendment shall automatically expire at the end of the term
         specified in Section 12 hereof unless specifically renewed prior
         thereto by mutual consent given in writing by the parties hereto.

8.2      This Amendment may be terminated prior to the completion of the term
         specified in Section 8 hereof:

         1)       By mutual consent given in writing by the parties hereto;

         2)       By either party at will with or without cause upon not less
                  than thirty (30) days' notice in writing by registered mail,
                  cable, or personal delivery to the other party, or


                                       5




         3)       By Seller upon one (1) day's like notice in the event:

                  (i)      Buyer ceases to conduct its operations in the normal
                           course of business

                  (ii)     A receiver for Buyer is appointed or applied for, or
                           it otherwise takes advantage of an insolvency law, or

                  (iii)    Buyer breaches this Agreement or acts in any manner
                           deemed by the Seller to be detrimental to the best
                           interests of Seller

         Without limitation, the foregoing events shall be deemed to be cause
         for termination by the Seller. Termination of the Seller shall not
         relieve either Party of any obligation arising out of work performed
         prior to termination.

                               9. General Clauses

9.1      Except as provided in the Article entitled "Limitation of Liability,"

         Amendment (by way of a waiver of a term or of a breach) by either party

9.5      The following Articles shall survive termination of the Amendment:
         Article 6 (Limitation of Liability), Article 9 (General Clauses) and

         entire agreement between the parties and no modification, amendment,
         rescission, waiver or other change shall be binding on either party

         representatives. Any oral or written representation, warranty, course

be necessary to effect the assignment or novation. Seller guarantees the
performance of its subsidiaries after the assignment or novation takes effect.

under this order without Seller's prior written consent shall be void.
