2.       Fairchild Semiconductor, Inc. with its address set out in Section Three
         of the First Schedule (hereafter called "FSC" or "Fairchild") of the
         other part.


         WHEREAS:

1.       Fairchild is engaged in the business of designing, manufacturing and
         marketing semiconductor devices.

2.       Assembler is engaged in the business of manufacturing various
         electronic components and semiconductor devices.

3.       This assembly agreement is applicable only to the list of packages
         referenced in Section One and Two of the Second Schedule.

4.       The parties mutually desire that the Assembler assemble certain
         integrated circuits designed by Fairchild subject to the terms and
         conditions below.

5.       The parties also mutually desire that the Assembler provide final test
         service on assembled packages listed in the Second Schedule, Section
         One.

         NOW, THEREFORE, the parties hereto agree as follows:

1.       SCOPE OF WORK

         a)       Assembler shall perform certain semiconductor assembly and
                  final test work for Fairchild. The semiconductor devices
                  (hereafter the "Devices") shall be assembled and/or tested in
                  a good and workmanlike manner in accordance with Assembler's
                  standard specifications and Fairchild's specific
                  specifications listed in the Third Schedule (hereafter the
                  "Specifications").

         b)       Notwithstanding anything contained herein to the contrary,
                  Fairchild reserves the right to engage any other subcontractor
                  to perform any assembly and/or final test work on a per need
                  basis. This agreement shall in no way be interpreted or
                  construed to be an exclusive dealing with the Assembler.



2.       TERMS

                                       2


         a)       The term of this Agreement is as stipulated in Section Four of
                  the First Schedule. Fairchild will notify Assembler is writing
                  ninety (90) days prior to the expiration of this Agreement
                  whether or not it desires to renew this Agreement. Should
                  Fairchild desire such a renewal, then both parties will enter
                  into a good faith negotiation regarding the same. Failure by
                  Fairchild to provide such notice to Assembler shall be deemed
                  to be notice by Fairchild that it does not desire to renew
                  this Agreement. If Assembler is not notified 90 days prior to
                  the expiration of this Agreement, then Assembler should make
                  reasonable effort to begin a dialogue with Fairchild
                  concerning the plans of both parties.

         b)       Fairchild shall be entitled, in its sole discretion, to renew
                  this Agreement for at least one additional year term under the
                  same terms and conditions stated herein, by notification to
                  Assembler at least ninety (90) days prior to the expiration of
                  this Agreement.


3.       MATERIALS / FACILITIES

         a)       Assembler shall supply all materials related to the assembly,
                  except for the items listed in Section Five of the First
                  Schedule.

                  The items listed in Section Five of the First Schedule may be
                  updated by the parties from time to time, at the request of
                  Fairchild, but at a minimum once per quarter. Fairchild shall
                  mark the equipment in such a manner as to serve notice to all
                  third parties that such equipment is owned solely by
                  Fairchild.

                  Assembler shall not place any contrary marks upon Fairchild
                  equipment and shall confirm to any third party Fairchild's
                  ownership of such listed equipment.

                  Assembler shall cooperate with Fairchild in making any filings
                  or registration permitted by applicable law to publish
                  Fairchild's ownership of said equipment, including, without
                  limitation, any filings or registrations permissible, if any,
                  under the Thailand Registration of Machinery Act (No. 2) B.E.
                  2530 (1987).

                  Assembler agrees that Fairchild may, upon reasonable notice,
                  enter Assembler's premises to recover said equipment in a
                  non-disruptive manner, regardless of whether the Assembler is
                  in default of this Agreement. Assembler agrees to cooperate
                  fully with any Fairchild efforts to retrieve any and all said
                  equipment. Assembler further agrees to maintain said equipment
                  in reasonable working order, with reasonable wear and tear
                  excepted.

                                       3


         b)       Assembler shall ensure that all materials and assembly
                  processes used to assemble Fairchild's Devices are free of
                  ODC's (Ozone Depleting Chemicals).

         c)       Assembler shall be responsible for supplying the assembly and
                  final test facilities and all equipment (unless otherwise set
                  forth in this Agreement) and personnel necessary to perform
                  assembly and/or test work contemplated hereunder. Unless
                  Assembler has received Fairchild's prior written consent
                  otherwise, all assembly and/or test work shall be performed at
                  the facility specified in Section Two of the First Schedule
                  hereto.

         d)       Fairchild agrees to accept the liability for any unique raw
                  materials that the Assembler has purchased for Fairchild's
                  Devices, if unused, provided that the Assembler has purchased
                  this inventory using Fairchild's 8 period rolling forecast and
                  used reasonable lead time provided by the vendor. Any excess
                  to this amount is the responsibility of the Assembler.

                  Fairchild's liability for such raw material shall be subject
                  to right of setoff against any amounts owed by Assembler to
                  Fairchild hereunder.

                  Fairchild's shall be liable under this Paragraph only to the
                  extent Assembler can deliver such raw materials to Fairchild
                  free and clear of all liens and encumbrances of others.


4.       ASSEMBLY PLAN

         a)       For information and planning purposes, Fairchild will provide
                  Assembler with a eight (8) period rolling forecast (hereafter
                  the "Forecast") with quantities by package type as shown in
                  Section One of the Second Schedule.

         b)       A new Forecast shall be due during the last week of each
                  period (Fairchild's fiscal year calendar) and Assembler shall
                  respond to the Forecast with a one hundred percent (100%) firm
                  assembly commitment for the first period within five (5)
                  working days as long as the immediate period forecast is not
                  higher than that committed in the previous period.

         c)       Based on the Forecast provided by Fairchild, Assembler shall
                  ensure that the proportionate weekly capacity is available to
                  enable linear loading of Fairchild's orders. Fairchild shall
                  make reasonable effort to ensure linear loading to the
                  Assembler.

         d)       If Assembler starts factory program material more than thirty
                  (30) days ahead of customers request data, then the Assembly
                  assumes liability

                                       4


                  for the total value of the product unless the starts are
                  authorized by Fairchild.

5.       PRICES

         a)       The prices to be paid by Fairchild for devices assembled
                  and/or tested pursuant to this agreement shall be mutually
                  agreed to by both Assembler and Fairchild. A Pricing Agreement
                  shall be documented noting effectivity date, and signed by
                  representatives of both the Assembler and Fairchild. A Pricing
                  Agreement shall be incorporated in this agreement into by
                  reference in Section Two, Second Schedule, and will be
                  expressed in U.S. Dollars. Prices shall be negotiated on an
                  annual basis, as a minimum. Updates on a quarterly basis shall
                  be permitted when mutually agreed upon between Assembler and
                  Fairchild. Yields used in determining the pricing shall be
                  reviewed on an annual basis, as a minimum.

         b)       All prices are to be expressed in terms of unit pricing that
                  include all the materials supplied by the Assembler unless
                  otherwise specified. Pricing shall reflect whether product is
                  to be standard packed in tubes or packed utilizing tape and
                  reel.

         c)       Unit pricing that is reduced contingent on specific minimum
                  volumes shall be documented on the Pricing Agreement. Failure
                  by Fairchild to meet the minimum quantity volumes required
                  shall result in a quarterly penalty payment. Penalty payment
                  shall be calculated as in the example provided below:

                  o        Volume Price Break   500KU per week
                  o        Actual Volume Load   400KU per week
                  o        Penalty Payment      1.3MU times (base price less 
                                                volume price)

         d)       Prices agreed by both Assembler and Fairchild shall be
                  effective throughout the term of this contract except as
                  updated quarterly by mutual agreement between the Assembler
                  and Fairchild. Any cost improvement or steps taken by
                  Fairchild to reduce the existing price shall be incorporated
                  into the Pricing Agreement in the quarter immediately
                  following the identification and acceptance of reduction by
                  the Assembler. Any cost reduction generated by the Assembler
                  through improved utilization or efficiency of equipment and/or
                  operators being employed shall benefit the Assembler
                  exclusively until the next contractual pricing agreement is
                  incorporated.

         e)       New products introduced by Fairchild for the Assembler to
                  assemble and/or final test shall be priced through mutual
                  agreement between Fairchild and Assembler. Pricing of new
                  products shall follow the

                                       5


                  format mutually agreed to in the Pricing Agreement by both
                  Assembler and Fairchild.


6.       PAYMENT TERMS

         a)       Payment to Assembler by Fairchild shall be made on a Net

8.       YIELD


                                       6


         a)       Assembler shall use its best efforts to meet the Assembly /
                  Test Yields defined in Section Four of the Second Schedule.

         b)       Assembly yield shall be measured by acceptable assembled
                  Devices shipped versus the number of good die the Assembler
                  received and shall be assessed over a thirty (30) day time
                  period on a per package and per lead count basis. Should the
                  yield performance fall five percent (5%) below that specified
                  in Section Four of the Second Schedule, Assembler shall submit
                  a specific explanation to Fairchild for review and the cost of
                  indemnification shall be mutually determined and agreed upon
                  between Fairchild and Assembler on a case to case basis,
                  unless otherwise specified in Section Four of the Second
                  Schedule.

         c)       Should the yield performance fall below minimum contract yield
                  that is specified in Section Four of the Second Schedule on a
                  lot to lot basis, Assembler shall notify Fairchild
                  immediately. A specific explanation in the standard report
                  format shall be submitted to Fairchild for review within the
                  next seven (7) days.

         d)       For assembly of untested Devices only, Fairchild will perform
                  "First Test" testing on the Devices received from the
                  Assembler at Fairchild's test location and will report the
                  test results to Assembler on a weekly basis, or as and when
                  the need arises, to assist Assembler in monitoring its
                  assembly performance.

         e)       Assembler shall calculate yield variance as defined by
                  Attachment A of the Second Schedule Section Four every period
                  (per Fairchild Fiscal Year Calendar). Yields may be adjusted
                  each quarter if mutually agreed to by both assembler and
                  Fairchild. A reclaim process shall be implemented by Assembler
                  to reduce the amount of negative variance claimed against
                  Fairchild for E2PROM products. The reclaim procedure shall be
                  as defined in Attachment B of the Second Schedule Section Four
                  attached herein.

         f)       Yield variance claims by the Assembler shall be as defined of
                  the Second Schedule, Attachment A and are subject to the
                  concurrence and approval of Fairchild.

         g)       Fairchild reserves the right to reprocess finished goods in an
                  effort to maximize utilization of its inventories. Procedures
                  and pricing of reprocessed materials is defined in the Second
                  Schedule Section Four, under Attachment C.

         h)       Fairchild shall have the right to terminate this Agreement
                  should Assembler be unable to meet agreed upon yield levels
                  within ninety (90) days of notification from Fairchild.

                  the duly authorized officers of the respective parties, shall
                  become the addendum of the original Schedules and by this
                  reference made a part hereof.

22.      WAIVER

         Should any party fail to enforce any provision of this Agreement or to
         exercise or waive any right in respect hereto, such failure or waiver
         shall not be constructed as constituting a waiver or a continuing
         waiver of its rights to enforce such provisions or right or any other
         provision or right.

         provisions which in effect will, from an economic viewpoint, most
         nearly or fairly approach the effect of the invalid provision.

                  shall not be precluded if such disclosure is in response to a
                  valid order of a court or other government body, provided that
                  the receiving party promptly notifies the other party of such
                  order and makes a good faith effort, at the expense of the
                  party which originally disclosed the information, to obtain a
                  protective order requiring the Confidential Information so
                  disclosed be kept in confidence and used only for the purpose
                  for which such order was issued.

                  shall provide Fairchild , upon reasonable request, additional
                  financial information related to or reasonably necessary to
                  assess Assembler's financial ability to perform its

                         Attachment A of second schedule

                     Yield Variance Computation Methodology

                              (refer to Clause 8E)



1 Yield Variance shall be computed by Process flow by NSPN.

2 Engineering Database System shall be used for Yield Variance computation.

3 Yield Variance shall be calculated on prime processing (B Type) Only.

4 The Formula for Yield Variance calculations are as follows:


                                           
  a)  Yield Variance in favor of Assembler=   (1/ "Actual Yield" - 1/Contract Yield) X "pack-out Qty"

                                               X (Untested Package Cost + Final Test Cost).



  b)  Yield Variance in favor of National=     (1/ "Actual Yield" - 1/Contract Yield) X "pack-out Qty"

                                                X  Untested Package Cost.




Notes:

     "Actual Yield" shall mean the cumulative of all the yields for the prime
     operations for each NSPN according to the respective Manufacturing Flow and
     with the yields FIXED for the workmanship related operations as shown
     below:



                    Operation                          Fixed Yield
                    ---------                          -----------
                                                     
                    Burn-In                            100%

                    Tape & Reel                        100%

                    FOI                                99.65%

                    Pack                               100%




     "Pack-out Qty" shall mean the pack-out quantity for the prime (B-type
     processing) lots only excluding the reclaim (C-type processing) lots and
     engineering (R-type processing) lots.

     Untested Package Cost is the TC13x Assembly Cost in Contract Price List.



     Assembler shall be responsible to ensure the correlation of Yield Variance
     Report quantities to Engineering Database Report and R563 LOTS Report
     quantities at all inventory points.

                  NM93CS*LZEM8/LZEN/LZM8/TLZEM8     1HT1/2HT1        Bin 3& Bin 5


                  ("*"= the numeric that refers to a specific device type)

2.   The identified fallouts above mentioned shall be transfered to EB3299
     inventory bucket and a report generated at each period end.

3.   Assembler shall be responsible to batch the fallouts for transfer from
     EB3299 to FA 6 (Function Area 6) of LOTS System which is designed for
     Reclaim processings, or other mutually agreed locale, upon elimination of
     LOTS system.

4.   Assembler shall calculate the Reclaim gain in favor of National on a
     periodic basis using below Formula or an alternative later agreed between
     the Assembler and National.

     Reclaim Gain in favor of National= "Reclaim Pack-out Qty" x Tested Package
     Cost - (Reclaim Pack-out Qty" / "Reclaim Cum Yld" x Final Test Cost)

5.   NSEB will be responsible for minimum quantities of reclaimed mat'ls to be
     retested at 30K day average. This minimum quantities include the reprocess
     mat'ls which require black ink and remarked. The minimum number is
     changeable when both parties agree.

Notes:

     "Reclaim Pack-out Qty" shall mean the pack-out quantity of the reclaimed
     lots under C-type processing per Engineering Database Report. "Reclaim Cum
     Yield" shall mean the cumulative of all the yields for the operations the
     reclaimed lots have undergone. Tested Package Cost is the TC11x Finished
     Goods Cost in Contract Price List.

6.   Assembler shall be responsible to ensure the correlation of Reclaim
     Report's quantities by NSPN to Engineering Database Report and R563 LOTS
     Report quantities at all inventory points.
