the Parties as expressed in the Purchase Agreement, Revenue Side Letter of even
date herewith (the "Revenue Side Letter") and other Operating Agreements (as
defined in Paragraph 9.1); and

      WHEREAS, the execution and delivery of this Agreement is a condition
precedent to the closing of the transactions contemplated by the Purchase
Agreement.

      NOW, THEREFORE, in furtherance of the foregoing premises and in
consideration of the mutual covenants and obligations hereinafter set forth, the
Parties hereto, intending to be legally bound hereby, do agree as follows:

1.0     DEFINITIONS

        1.1    "Acceptance Criteria" shall mean the electrical parameter
               testing, process control monitor ("PCM") and other inspections
               for each Product and/or Process as set forth in Exhibit F hereto,
               all of which are to be performed by Fairchild prior to shipment
               of Wafers hereunder.

        1.2    "Best Efforts" shall require that the obligated Party make a
               diligent, reasonable and good faith effort to accomplish the

               any material expenditure of funds or the incurrence of any
               material liability on the part of the obligated Party, which
               expenditure or liability is unreasonable in light of the related
               objective, nor does it require that the obligated Party act in a
               manner which would otherwise be contrary to prudent business
               judgment or normal commercial practices in order to accomplish
               the objective. The fact that the objective is not actually
               accomplished is no indication that the obligated Party did not in
               fact utilize its Best Efforts in attempting to accomplish the
               objective.

3.0     PROCESSES

        3.1    Exhibit A lists the Processes which Fairchild shall use in
               manufacturing Wafers hereunder for National. Exhibit A may be
               amended from time to time by mutual agreement in writing of the
               Parties, as new processes are developed and older Processes
               become obsolete.

        3.2    After qualification is successfully completed for any Product to
               be manufactured under this Agreement, if Fairchild desires to
               make material Process changes affecting form, fit or function,
               Fairchild will notify National of the intended change in
               accordance with Fairchild's process change procedures then in
               effect. If the proposed changes are unacceptable to National,
               National and Fairchild shall work together in efforts to resolve
               the problem and qualify the changed Process for making Wafers. If
               the Parties are unable to resolve the problem, Fairchild shall
               have the right to make such Process changes upon the provision of
               twelve (12) fiscal periods prior written notice to National.
               Subsequent to Fairchild's notice of Process change, Fairchild
               will make provisions with National for Last Time Buys, and commit
               to ship all Wafers requested in such last Time Buys as the
               Parties may negotiate.

        3.3    Should Fairchild elect to discontinue a Process, it must give
               National written notice of no less than twelve (12) fiscal
               periods prior to the date it intends to discontinue any Process
               or its future amended form. Subsequent to Fairchild's notice of
               Process discontinuance, Fairchild will make provisions with
               National for Last Time Buys, and commit to ship all Wafers
               requested in such Last Time Buys as the Parties may negotiate.

4.0     SET UP AND QUALIFICATION OF NEW PRODUCTS

        4.1    With Fairchild's written approval, which approval shall not be
               unreasonably withheld, National will be allowed to develop, at
               its own expense, Mil/Aero versions of Fairchild products,
               including derivatives of and improvements to existing products.

        4.2    For each new Product that National proposes to have 


                                      -6-


               Fairchild manufacture, National will provide to Fairchild in
               advance the Specifications and design layout of the Product for
               review and comment by Fairchild. The Parties will also agree on
               the Acceptance Criteria, including electrical test parameters,
               and Quality and Reliability Criteria for the prototype Wafers to
               be manufactured for the new Product during the qualification
               process.

        4.3    An initial data base for Mask generation or pattern generation,
               or acceptable production Masks will be provided by National to
               Fairchild, per Fairchild specifications, at National's expense,
               for each new Product to be fabricated for National, if required.
               In the alternative, National may provide Fairchild with prime die
               design data and Fairchild will provide the frame and fracture
               services and procure the Mask set at National's expense. After
               receipt of the initial data base, or pattern generation tape, or
               master or sub-master Mask set, additional and/or replacement Mask
               sets shall be the responsibility and expense of Fairchild. All
               such data bases, pattern generation tapes and Mask sets shall be
               the property of National, regardless of whether they were
               initially supplied by National or replaced by Fairchild, for Mask
               works developed by National.

        4.4    As soon as practical following agreement on the items in
               Paragraph 4.2 above, and following receipt of a written purchase
               order from National, Fairchild will begin manufacture of twelve
               (12) prototype Wafers for such Product as is specified in the
               purchase order. Fairchild will perform the electrical testing
               specified in the initial Acceptance Criteria and supply the test
               data to National with the prototype Wafers. Fairchild's
               obligation shall be limited to providing Wafers that meet the
               applicable PCM specifications and the associated test data.
               National will promptly inspect the prototype Wafers and notify
               Fairchild in writing of the results. If the prototype Wafers do
               not meet the Acceptance Criteria and Quality and Reliability
               Criteria, the Parties will cooperate in good faith to determine
               the reason for such failure.

        4.5    In connection with the completion of the qualification process
               for any new Product, National will deliver to Fairchild final
               Specifications for the Product incorporating any changes agreed
               in writing by the Parties during the qualification process. The


                                      -7-


               Parties will also negotiate for each Product the final Acceptance
               Criteria and Quality and Reliability Criteria to be used for the
               commercial production lots of Wafers.

        4.6    Unless otherwise agreed in writing production quantities of
               Wafers of a new Product will not be manufactured prior to
               completion of the qualification process under this Section 4. In
               the event that National desires for Fairchild to manufacture
               production quantities, the Parties will agree in writing on the
               terms before Fairchild accepts the purchase order.

5.0     MODIFICATION OF EXISTING PRODUCTS

        5.1    If either National or Fairchild desires to make any changes to
               the Masks, final Specifications, Acceptance Criteria or Quality
               and Reliability Criteria for an existing Product (including
               changes to a Fairchild product that is the basis for a National
               Product), that Party shall notify the other Party in writing and
               negotiate the changes in good faith, including any changes in
               prices required by such modifications. A modification to any of
               the foregoing will be binding only when a writing to which such
               modification is attached has been signed by both Parties as
               provided in this Agreement. The Parties will separately negotiate
               the price and terms of any prototype Wafers required in
               connection with such change. If any changes proposed by Fairchild
               are not acceptable to National, Fairchild will continue to
               manufacture the unchanged product for twelve (12) fiscal periods.
               During that time Fairchild will make provisions with National for
               Last Time Buys, and commit to ship all Wafers requested in such
               Last Time Buys as the Parties may negotiate.

6.0     PRODUCT OBSOLESCENCE

        6.1    Fairchild may at its discretion declare a Fairchild product
               obsolete. If the product forms the basis for a National Product
               then Fairchild may declare the device obsolete if it has not been
               run in production for eighteen (18) fiscal periods. Fairchild
               shall provide National with twelve (12) months prior written
               notice, make provisions with National for a Last Time Buy and
               commit to ship all Wafers requested 


                                      -8-


               in such Last Time Buys as the Parties may negotiate. If a product
               has not been run in production for six (6) fiscal periods by
               either Fairchild or National then Fairchild will notify National
               in writing and the following surcharge will apply to the price of
               any such product:

               four (4) inch wafers, 25% of the latest negotiated price

               five (5) inch wafers, 25% of the latest negotiated price

               six (6) inch wafers, 10% of the latest negotiated price

               After the Last Time Buy has expired, Fairchild may sell the Mask
               set and associated tooling to an established after-market
               supplier such as Rochester Electronics. Should Fairchild elect
               not to sell the Mask set and tooling to a third party then
               National will have the option of purchasing the Mask set etc., in
               which case National will retain only the military rights to the
               product.

7.0     CAPACITY; VOLUME COMMITMENTS; PRODUCTION PLANNING

        7.1    Production under this Agreement will use the procedures, terms,
               and conditions described in Section 5 of the Fairchild Foundry
               Services Agreement between the Parties of even date herewith.

        7.2    All production under this Agreement will be included as part of
               the total National Capacity Request and Fairchild Assured
               Capacity as defined in Section 5 of said Fairchild Foundry
               Services Agreement.

8.0     PURCHASE ORDERS

        8.1    All purchases and sales between Fairchild and National shall be
               initiated by National's issuance of written purchase orders sent
               by either first class mail or facsimile. By written agreement of
               the Parties, purchase orders may also be sent and acknowledged by
               electronic data exchange or other mutually satisfactory system.
               Such "blanket" purchase orders shall be issued once per fiscal
               quarter for Wafers to be delivered three (3) fiscal periods 


                                      -9-


               in the future. They shall state the Wafer quantities (specifying
               whether equivalents or actual) by Wafer Module, and shipping and
               invoicing instructions. Fairchild shall accept purchase orders
               through a written or electronic acknowledgment. Within a
               reasonable time after receipt of National's detailed device level
               Wafer starts request for the next fiscal period, Fairchild shall
               provide National with a Product delivery schedule either on a
               weekly basis as the Wafers are started or for the Wafer starts
               for the entire fiscal period, as the Parties may agree in
               writing. The purchase orders may utilize the first three (3)
               fiscal periods forecast in the eight period rolling forecast
               supplied pursuant to Section 7, as the embodiment of the purchase
               order for specifying the Wafer quantity by Wafer Module and
               Process, and whether sorted or unsorted.

        8.2    In the event of any conflict between the terms and conditions of
               this Agreement and either Party's purchase order, acknowledgment,
               or similar forms, priority shall be determined as follows:

               (a)   typewritten or handwritten terms on the face of a written
                     purchase order, acknowledgment or similar document or in
                     the main body of an electronic equivalent which have been
                     specifically accepted in writing by the other Party's
                     Program Manager;

               (b)   the terms of this Agreement;

               (c)   preprinted terms incorporated in the purchase order,
                     acknowledgment or similar document.

        8.3    Consistent with standard practices of issuing specific device
               level details of part numbers to be fabricated on a weekly or
               periodic basis, National may unilaterally change the part number
               to be manufactured, provided that Fairchild agrees that the
               change does not negatively impact Fairchild's loadings and
               provided further that there is no change in the Process flow to
               be used. A change that will negatively impact loading or alter
               the Process flow may only be directed upon Fairchild's written
               agreement, which shall utilize its Best Efforts to comply with
               such requested change. The specific part number detail shall be
               submitted by first class mail or facsimile. By written agreement
               of the Parties specific part number detail may also be sent by


                                      -10-


               electronic data exchange, or other mutually satisfactory system.

        8.4    National shall request delivery dates which are consistent with
               Fairchild's reasonable lead times for each Product as indicated
               at the time National's purchase order is placed. Notwithstanding
               the foregoing, Fairchild shall utilize its Best Efforts to
               accommodate requests by National for quick turnarounds or "hot
               lots", which includes prototype lots. Hot lot cycle times and the
               premiums to be paid therefor are listed in Exhibit K. Level S hot
               lots will be negotiated on a case-by-case basis.

        8.5    Fairchild may manufacture lots of any size which satisfy the
               requirements of effective manufacturing. However, National must
               place orders for full flow and prototype Products in increments
               of [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
               THE SECURITIES AND EXCHANGE COMMISSION] Wafers for lots that are
               run exclusively for National with National Masks, or, when
               possible, as agreed by Fairchild, in [CONFIDENTIAL INFORMATION
               OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
               COMMISSION] increments if scheduled as a portion of a Fairchild
               product lot started for Fairchild's use. For personalized ASIC
               Wafers drawn from mid-flow inventories, the smallest quantity
               that shall be ordered by National is [CONFIDENTIAL INFORMATION
               OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
               COMMISSION], except for Wafers manufactured in the five-inch (5")
               fab, in which case the smallest quantity that can be ordered is
               [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
               SECURITIES AND EXCHANGE COMMISSION].

               at its discretion, may request a controlled electronic copy of
               the required information in lieu of the paper copy. Fairchild
               will provide the foregoing services at no charge to National,
               limited to those engineering services performed as of the
               Effective Date.

11.0    DELIVERY; RESCHEDULING AND CANCELLATION

        11.1   Fairchild shall make reasonable and diligent efforts to deliver
               Wafers on the delivery dates specified in


                                      -14-


               the Product delivery schedule provided by Fairchild pursuant to
               Paragraph 8.1. Any shipment made within fifteen (15) days before
               or after the shipment date(s) specified in said Product delivery
               schedule shall constitute timely shipment. Partial shipments will
               be allowed and may be invoiced separately. A delivery will be
               considered conforming if it contains a quantity equal to plus
               five percent (5%) or minus twenty percent (20%) of the quantity
               ordered.

        11.2   Except in the case of Level "S" wafers, which are
               non-cancellable, if Fairchild has not made shipment of Products
               within fifteen (15) days after the shipment date specified in the
               Product delivery schedule provided by Fairchild pursuant to
               Paragraph 8.1, National shall have the right, subject to
               Paragraph 20.2, to cancel that portion of its purchase order
               pertaining to such Products, but only in the event that
               National's customer for those Products has cancelled its order
               with National for such Products. Notwithstanding the foregoing,
               if Fairchild has not made shipment of Products within thirty (30)
               days after the shipment date specified in the Product delivery
               schedule, National shall have the right, subject to Paragraph
               20.2, in its sole discretion, to cancel that portion of its
               purchase order pertaining to such Products, regardless of whether
               National's customer has cancelled its order with National or not.
               In either event, any obligation of National under its Capacity
               Request and/or any commitment to Fairchild under the Revenue Side
               Letter associated with such cancelled purchase order shall be
               discharged in full and National shall have no liability
               whatsoever to Fairchild therefore.

        11.3   All Wafers delivered pursuant to the terms of this Agreement
               shall be suitably packed for shipment in Fairchild's standard
               containers, marked for shipment to National's address set forth
               in the applicable purchase order and delivered to a carrier or
               forwarding agent chosen by National. Should National fail to
               designate a carrier, forwarding agent or type of conveyance,
               Fairchild shall make such designation in conformance with its
               standard shipping practices. Shipment will be F.O.B. shipping
               point, at which time risk of loss and title shall pass to
               National. Shipments will be subject to incoming inspection as set
               forth in Paragraph 12.2 below.

        11.4   To facilitate the inspection of Product deliveries to 


                                      -15-


               National, lot integrity shall be maintained on all such
               deliveries, unless specifically waived by mutual agreement of the
               Parties.

        11.5   Subject to the provisions of Section 8 hereof, National may
               cancel any purchase order upon at least one (1) week's notice
               prior to the commencement of manufacturing without charge,
               provided that National reimburses Fairchild for the cost of any
               unique raw materials purchased for such order.

        11.6   National may request that Fairchild stop production of Wafers in
               process for National's convenience and Fairchild shall consider
               stopping depending on the point of process. In such event,
               National shall pay for all Wafers at the agreed price, subject to
               a negotiated adjustment based upon the degree of completion of
               the Wafers and whether or not Fairchild is able to utilize the
               unfilled capacity. Fairchild will, if reasonably practicable,
               restart production of stopped Wafers one time within a reasonable
               time after receipt of a written request from National, subject to
               National's payment of any additional expenses incurred. Sections
               12, 13, and 14 of this Agreement shall not apply to Wafers
               stopped under this Paragraph 11.6 for more than thirty (30) days,
               nor shall Fairchild make any commitments of yield with respect to
               such Wafers.

        11.7   In the event that National elects to maintain an inventory of
               partially finished Wafers, ownership of the partially finished
               Wafers will pass to National when they reach the holding point
               defined by the relevant Process flow. Fairchild will invoice
               National for such Wafers, but they will be stored under
               clean-room conditions and remain in the Wafer processing WIP
               management system. Fairchild will inform National of the number
               and types of these Wafers remaining in inventory at the end of
               each fiscal period. Further, the electronic records and physical
               inventory shall be available for inspection by National at any
               time. Fairchild shall credit National with the amount previously
               invoiced for any such Wafers at such time as they are restarted
               in the Process flow.

        11.8   As of 12:01 A.M. on the Effective Date, National will own all
               Wafers located at the Facility which Fairchild has commenced
               processing but which have not yet been completed in accordance
               with the pertinent 


                                      -16-


               Process flow. Unless expressly directed in writing by National
               otherwise, Fairchild shall continue to process each Wafer to a
               normal state of completion in the applicable Wafer Module.
               National shall pay Fairchild for the accumulated additional
               processing costs, plus a twenty-five percent (25%) mark up, for
               the additional processing taking place on and after the Effective
               Date. The provisions of Sections 12, 13, and 14 hereof shall
               specifically apply to all such Wafers.

12.0    QUALITY CONTROL AND INSPECTION; AND RELIABILITY

        12.1   Fairchild will manufacture Wafers in accordance with the Quality
               and Reliability Criteria for the applicable Product. Prior to
               shipment, Fairchild will perform the electrical parameter testing
               and other inspections specified to be performed by it in the
               applicable Acceptance Criteria on each Wafer lot manufactured.
               Fairchild will only ship those Wafer lots that successfully pass
               the applicable Acceptance Criteria. Fairchild will electronically
               provide National with the electrical test data specified in the
               applicable Acceptance Criteria. Wafers will be laser scribed with
               lot and wafer number for statistical monitoring and lot number
               traceability.

        12.2   National shall promptly provide for inspection and testing of
               each shipment of Wafers upon receipt in accordance with the
               Acceptance Criteria and shall notify Fairchild in writing of
               acceptance of the Wafers. If National has not given written
               notice to Fairchild of rejection of all or part of a shipment
               within thirty (30) days of receipt, National will be deemed to
               have accepted such Wafers. In the event any lot or Wafer is found
               to fail the Acceptance Criteria prior to final acceptance,
               National shall promptly return it to Fairchild, together with all
               test data and other information reasonably required by Fairchild.
               Upon confirmation by Fairchild that such Wafers fail the
               Acceptance Criteria, Fairchild shall replace such lot or Wafer on
               a timely basis.

        12.3   National shall promptly provide for yield probe tests to be
               conducted on the Wafers and communicate the results of the tests
               to Fairchild within thirty (30) days of receipt of Wafers from
               Fairchild. The right to return any Wafers for low yield shall be
               governed by Section 11 below.


                                      -17-


        12.4   MPS-3-000 (Material Procurement Specification) - General
               Provisions and Quality Requirements for External (Non-National)
               Wafer Fab Facilities and MPS-3-001 (Material Procurement
               Specification) - Technical Requirements for CMOS Processing are
               the National policies for the purchase of integrated circuits
               from independent suppliers. These policies as in effect at the
               Effective Date shall provide criteria for the initial and
               continuing qualification of the Facility and evaluation of Wafers
               manufactured by Fairchild hereunder. To the extent that those
               policies are not inconsistent with the provisions of this
               Agreement, National shall not be required to accept delivery of
               any Wafers hereunder if Fairchild fails to comply with said
               policies or such other similar policies as may be mutually agreed
               to by the Parties.

        12.5   Fairchild hereby warrants that the Facility currently is, and
               will remain throughout the term of this Agreement, ISO9000
               certified.

13.0  MINIMUM YIELD ASSURANCES

        13.1   Fairchild will guarantee a minimum yield assurance ("MYA") on a
               per Product basis for those Wafers fabricated and probed by
               Fairchild. MYAs shall function as a reliability screen hereunder
               for maverick Wafers, via standard sort test results and yield.
               For Wafers not sorted by Fairchild, the MYA limits will apply
               only to Wafers whose substandard yield is caused by materials or
               Fairchild workmanship.

        13.2   For a new Product, the baseline yield and MYA will be established
               after a minimum of twenty (20) Wafer lot runs have been tested to
               production released test programs. A new baseline yield and MYA
               will be calculated whenever National makes any modifications to
               said test programs.

        13.3   Each fiscal quarter, each Product's baseline yield will be
               calculated using the previous fiscal quarter's results, or the
               previous twenty (20) Wafer lot runs if less than twenty (20)
               Wafer lot runs were processed in said previous quarter. The mean
               and standard deviation (sigma) yield for a Product will be
               calculated using individual Wafer data. Zero 


                                      -18-


               yielding Wafers will be excluded from such calculations. The
               results of such calculations will be used in defining the MYA for
               that Product for the quarter in which the calculations are made,
               but only if the mean yield changes by more than +/-2%.

        13.4   MYA will be determined as follows. Wafers which yield less than
               sixty percent (60%) of the baseline yield for the commercial
               version of the Product will be considered discrepant and may be
               returned for full credit at National's discretion. In no event
               shall Fairchild accept returns of Wafers on non-released
               products. For Level "S" Fact 2.0 Wafers the MYA will be fifty
               percent (50%) of the baseline yield for the commercial version of
               the Product. For Mil/Aero products that yield significantly less
               than their respective commercial versions, the MYA will be
               negotiated on a case by case basis.

        13.5   National shall provide yield analysis information on Wafers
               returned to Fairchild under this Section 13, in order to assist
               Fairchild in continuous Process improvement.

        13.6   In the event of an extended period of substandard yields on a
               Product, Fairchild will utilize its Best Efforts to correct any
               Process related causes and the Parties will negotiate in good
               faith to make up for the yield loss experienced by National and
               its customers.

 14.0   WARRANTY

        14.1   Fairchild warrants that the Products delivered hereunder shall
               meet the Quality and Reliability Criteria and shall be free from
               defects in material and Fairchild's workmanship under normal use
               for a period of one (1) year from the date of delivery. If,
               during the one year period:

              (i)    Fairchild is notified in writing promptly upon discovery
                     with a detailed description of any such defect in any
                     Product (at which time Fairchild shall issue a return
                     material authorization number to National), and;
             (ii)    National returns such Product to the applicable Facility
                     at National's expense for inspection; and
            (iii)    Fairchild's examination of such Product reveals 


                                      -19-


                     that the Product is indeed defective and does not meet
                     the applicable Quality and Reliability Criteria or is
                     defective in materials or Fairchild's workmanship and
                     such problems are not caused by accident, abuse, misuse,
                     neglect, improper storage, handling, packaging or
                     installation, repair, alteration or improper testing or
                     use by someone other than Fairchild

               then, within a reasonable time, Fairchild, at its sole option,
               shall either replace or credit National for such defective
               Product. Fairchild shall return any Products replaced under this
               warranty to National transportation prepaid, and shall reimburse
               National for the transportation charges paid by National in
               returning such defective Products to Fairchild.

        14.2   THE FOREGOING WARRANTY CONSTITUTES FAIRCHILD'S EXCLUSIVE
               LIABILITY, AND NATIONAL'S EXCLUSIVE REMEDY, FOR ANY BREACH OF
               WARRANTY. EXCEPT AS SET FORTH HEREIN, FAIRCHILD MAKES AND
               NATIONAL RECEIVES NO WARRANTIES OR CONDITIONS ON THE PRODUCTS,
               EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, AND FAIRCHILD
               SPECIFICALLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR FITNESS
               FOR A PARTICULAR PURPOSE.

 15.0   ON-SITE INSPECTION AND INFORMATION

        15.1   Fairchild shall allow National and/or National's customers to
               visit and evaluate the Facility during normal business hours as
               part of established source inspection programs, it being
               understood and agreed between National and Fairchild that
               National must obtain the concurrence of Fairchild for the
               scheduling of all such visits, which such concurrence shall not
               be unreasonably withheld. It is anticipated that such visits will
               occur no more than once per quarter on average.

        15.2   National shall have access to fab audits conducted by Fairchild
               and fab baselines. Fairchild may charge a fee commensurate with
               the effort required to provide these baselines and audits.

        15.3   Upon National's written request, Fairchild will provide National
               with process control information, to include but not be limited
               to: process and electrical test yield results, current process
               specifications and conformance to specifications; 


                                      -20-


               calibration schedules and logs for equipment; environmental
               monitor information for air, gases and DI water; documentation of
               operator qualification and training; documentation of
               traceability through Fairchild's operation; and Fairchild
               verification information. Except for exigent circumstances, such
               requests shall not be made more than twice per year for a given
               category of information.

16.0    PRODUCT ENGINEERING SUPPORT

        16.1   The Parties will cooperate in allowing National employees to have
               reasonable access to the Facility during the term of this
               Agreement (the "National Engineering Team"), in order to assist
               in Product developments and improvements. Fairchild will provide
               reasonable office space to the National Engineering Team, if
               required on a temporary basis, not to exceed 60 days per
               occurrence, at no expense to National. Should the National
               Engineering Team require long term, dedicated office space,
               National agrees to pay Fairchild the overhead cost associated
               with such space. The National Engineering Team will comply with
               all applicable Fairchild regulations in force at the Facility and
               National hereby agrees to hold Fairchild harmless for any damages
               or liability caused by any member of the National Engineering
               Team, which are attributable to: (i) the negligence or willful
               malfeasance of such member, and (ii) any failure by such member
               to comply with Fairchild's regulations in force at the Facility
               or with applicable law.

        16.2   Fairchild shall assist the efforts of the National Engineering
               Team and provide National with reasonable and timely support.

        16.3   Fairchild shall assist National in any efforts to identify any
               reliability problems that may arise in a Product. National shall
               correct National Product related problems and Fairchild shall
               correct all Fairchild product and Process related problems.

17.0    TERM AND TERMINATION

        17.1   The term of this Agreement shall be thirty-nine (39) fiscal
               periods from the Effective Date; provided, however, that the
               Parties shall not less than eight 


                                      -21-


               (8) fiscal periods prior to the end of such thirty-ninth (39th)
               fiscal period determine in good faith a ramp-down schedule of
               production so as to minimize disruption to both Parties. If the
               Parties are unable to agree on the terms governing a ramp-down,
               National shall be allowed to reduce its purchase commitment by
               not more than twenty percent (20%) per fiscal quarter, starting
               one fiscal quarter after the initial thirty-nine (39) fiscal
               period term of this Agreement. National will provide Fairchild
               with not less than ninety (90) days prior written notice of such
               reduction.

        17.2   This Agreement may be terminated, in whole or in part, by one
               Party sending a written notice to the other Party of the
               termination of this Agreement, which notice specifies the reason
               for the termination, upon the happening of any one or more of the
               following events:

               (a)   the other Party is the subject of a petition filed in a
                     bankruptcy court of competent jurisdiction, whether
                     voluntary or involuntary, which petition in the event of
                     an involuntary petition is not dismissed within sixty
                     (60) days; if a receiver or trustee is appointed for all
                     or a substantial portion of the assets  of the other
                     Party; or if the other Party makes an assignment for the
                     benefit of its creditors; or

               (b)   the other Party fails to perform substantially any
                     material covenant or obligation, or breaches any
                     material representation or warranty provided for herein;
                     provided, however, that no right of termination shall
                     arise hereunder until sixty (60) days after receipt of
                     written notice by the Party who has failed to perform
                     from the other Party, specifying the failure of
                     performance, and said failure having not been remedied
                     or cured during said sixty (60) day period.

        17.3   Upon termination of this Agreement, all rights granted hereunder
               shall immediately terminate and each Party shall return to the
               other Party any property belonging to the other Party which is in
               its possession, except that Fairchild may continue to retain and
               use any rights or property belonging to National solely for the
               period necessary for it to finish manufacturing the currently
               forecasted Fairchild Assured Capacity. Nothing in this Section 17


                                      -22-


               is intended to relieve either Party of any liability for any
               payment or other obligations existing at the time of termination.

        17.4   The provisions of Sections 2, 6, 14, 18, 19 and Paragraphs 21.5
               and 21.8 shall survive the termination of this Agreement for any
               reason.

18.0    EXPORT CONTROL

        18.1   The Parties acknowledge that each must comply with all rules and
               laws of the United States government relating to restrictions on
               export. Each Party agrees to use its Best Efforts to obtain any
               export licenses, letters of assurance or other documents
               necessary with respect to this Agreement.

        18.2   Each Party agrees to comply fully with United States export laws
               and regulations, assuring the other Party that, unless prior
               authorization is obtained from the competent United States
               government agency, the receiving Party does not intend and shall
               not knowingly export or re-export, directly or indirectly, any
               Wafers, Products, technology or technical information received
               hereunder, that would be in contravention of any laws and
               regulations published by any United States government agency.

19.0    CONFIDENTIALITY

        19.1   For purposes of this Agreement, "Confidential Information" shall
               mean all proprietary information, including National and/or
               Fairchild trade secrets relating to the subject matter of this
               Agreement disclosed by one of the Parties to the other Party in
               written and/or graphic form and originally designated in writing
               by the disclosing Party as Confidential Information or by words
               of similar import, or, if disclosed orally, summarized and
               confirmed in writing by the disclosing Party within thirty (30)
               days after said oral disclosure, that the orally disclosed
               information is Confidential Information.

        19.2   Except as may otherwise be provided in the Technology Licensing
               and Transfer Agreement, each Party agrees that it will not use in
               any way for its own account, or for the account of any third
               party, nor disclose to any third party except pursuant to this
               Agreement, 


                                      -23-


               any Confidential Information revealed to it by the other Party.
               Each Party shall take every reasonable precaution to protect the
               confidentiality of said information. Each Party shall use the
               same standard of care in protecting the Confidential Information
               of the other Party as it normally uses in protecting its own
               trade secrets and proprietary information.

        19.3   Notwithstanding any other provision of this Agreement, no
               information received by a Party hereunder shall be Confidential
               Information if said information is or becomes:

               (a)   published or otherwise made available to the public
                     other than by a breach of this Agreement;

               (b)   furnished to a Party by a third party without
                     restriction on its dissemination;

               (c)   approved for release in writing by the Party designating
                     said information as Confidential Information;

               (d)   known to, or independently developed by, the Party
                     receiving Confidential Information hereunder without
                     reference to or use of said Confidential Information; or

               (e)   disclosed to a third party by the Party transferring said
                     information hereunder without restricting its subsequent
                     disclosure and use by said third party.

        19.4   In the event that either Party either determines on the advice of
               its counsel that it is required to disclose any information
               pursuant to applicable law or receives any demand under lawful
               process to disclose or provide information of the other Party
               that is subject to the confidentiality provisions hereof, such
               Party shall notify the other Party prior to disclosing and
               providing such information and shall cooperate at the expenses of
               the requesting Party in seeking any reasonable protective
               arrangements requested by such other Party. Subject to the
               foregoing, the Party that receives such request may thereafter
               disclose or provide information to the extent required by such
               law (as so advised by counsel) or by lawful process.

               numbers of the Program Managers will be communicated between the
               Parties from time to time.

 21.0   GENERAL

        21.1   AMENDMENT:  This Agreement may be modified only by a written
               document signed by duly authorized representatives of the
               Parties.

        21.2   FORCE MAJEURE: A Party shall not be liable for a failure or delay
               in the performance of any of its obligations under this Agreement
               where such failure or delay is the result of fire, flood, or
               other natural disaster, act of God, war, embargo, riot, labor
               dispute, unavailability of raw materials or utilities (provided
               that such unavailability is not caused by the actions or
               inactions of the Party claiming force majeure), or the
               intervention of any government authority, providing that the
               Party failing in or delaying its performance immediately notifies
               the other Party of its inability to perform and states the reason
               for such inability.

        21.3   ASSIGNMENT: This Agreement may not be assigned by any Party
               hereto without the written consent of the other Party; provided
               that Fairchild may assign its rights but not its obligations
               hereunder as collateral security to any bona fide financial
               institution engaged in acquisition financing in the ordinary
               course providing financing to consummate the transactions
               contemplated by the Purchase Agreement or any bona fide financial
               institution engaged in 


                                      -25-


               acquisition financing in the ordinary course through whom such
               financing is refunded, replaced, or refinanced and any of the
               foregoing financial institutions may assign such rights in
               connection with a sale of Fairchild or the Business in the form
               then being conducted by Fairchild substantially as an entirety.
               Subject to the foregoing, all of the terms and provisions of this
               Agreement shall be binding upon, and inure to the benefit of, and
               shall be enforceable by, the respective successors and assigns of
               the Parties hereto.

        21.4   COUNTERPARTS: This Agreement may be executed simultaneously in
               two or more counterparts, each of which shall be deemed an
               original and all of which together shall constitute but one and
               the same instrument.

        21.5   CHOICE OF LAW: This Agreement, and the rights and obligations of
               the Parties hereto, shall be interpreted and governed in
               accordance with the laws of the State of California, without
               giving effect to its conflicts of law provisions.

        21.6   WAIVER: Should either of the Parties fail to exercise or enforce
               any provision of this Agreement, such failure or waiver shall not
               be construed as constituting a waiver or a continuing waiver of
               its rights to enforce such provision or right or any other
               provision or right. Should either of the Parties waive any
               provision or right under this Agreement, such waiver shall not be
               construed as constituting a waiver of any other provision or
               right.

        21.7   SEVERABILITY: If any provision of this Agreement or the
               application thereof to any situation or circumstance shall be
               invalid or unenforceable, the remainder of this Agreement shall
               not be affected, and each remaining provision shall be valid and
               enforceable to the fullest extent.

        21.8   LIMITATION OF LIABILITY: IN NO EVENT SHALL EITHER PARTY BE LIABLE
               FOR ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
               RESULTING FROM THE OTHER PARTY'S PERFORMANCE OR FAILURE TO
               PERFORM UNDER THIS AGREEMENT, OR THE FURNISHING, PERFORMANCE, OR
               USE OF ANY GOODS OR SERVICES SOLD PURSUANT HERETO, WHETHER DUE TO
               BREACH OF CONTRACT, BREACH OF WARRANTY, NEGLIGENCE OR OTHERWISE,
               REGARDLESS OF WHETHER THE 


                                      -26-


               NON-PERFORMING PARTY WAS ADVISED OF THE POSSIBILITY OF SUCH
               DAMAGES OR NOT.

        21.9   EFFECT OF HEADINGS: The headings and sub-headings contained
               herein are for information purposes only and shall have no effect
               upon the intended purpose or interpretation of the provisions of

        21.10  INTEGRATION: The agreement of the Parties, which is composed of
               this Agreement and the Exhibits hereto and the documents referred

               between the Parties with respect to the subject matter of this
               Agreement and integrates all prior discussions and proposals
               (whether oral or written) between them related to the subject
               matter hereof.

        21.11  PUBLIC ANNOUNCEMENT: Prior to the closing of the transactions
               contemplated under the Purchase Agreement, neither Fairchild nor
               National shall, without the approval of the other Party hereto,
               make any press release or other public announcement concerning
               the terms of the transactions contemplated by this Agreement,
               except as and to the extent that any such Party shall be so
               obligated by law, in which case the Party shall use its Best
               Efforts to advise the other Party thereof and the Parties shall
               use their Best Efforts to cause a mutually agreeable release or
               announcement to be issued; provided that the foregoing shall not
               preclude communications or disclosures necessary to (a) implement
               the provisions of this Agreement or (b) comply with accounting
               and Securities and Exchange Commission disclosure obligations.
               Fairchild shall provide National with a reasonable opportunity to
               review and comment on any references to National made by
               Fairchild (and shall not include any such references to National
               without the written consent of National, which consent shall not
               be unreasonably withheld or delayed) in any written materials
               that are intended to be filed with the Securities and Exchange
               Commission in connection with obtaining financing required to
               effect the transactions contemplated in connection with the
               Purchase Agreement or intended to be distributed to prospective
               purchasers pursuant to an offering made under Rule 144A
               promulgated under the Securities Act of 1933 in connection with
               obtaining such financing.

        21.12  NO PARTNERSHIP OR AGENCY CREATED: Nothing contained herein or
               done pursuant to this Agreement shall 


                                      -27-


               constitute the Parties as entering upon a joint venture or
               partnership, or shall constitute either Party the agent for the
               other Party for any purpose or in any sense whatsoever.

        21.13  BINDING EFFECT:  This Agreement and the rights and obligations
               hereunder shall be binding upon and inure to the benefit of

                            WAFER ACCEPTANCE CRITERIA


Fairchild Electrical Test Acceptance Method:

Acceptance of Fairchild Wafers for shipment to National shall be determined per
mutually agreed upon electrical parameter test distribution performance with
standard test die. For the 


                                    Page 10


West Jordan, Utah fabs, all wafers will be subjected to the Acceptance criteria
specified in West Jordan specifications: SOP-3060, TS-3020 and TS-3021. For the
South Portland, Maine fabs, all Wafers will be tested to the electrical
specifications, by Process, listed in this Exhibit, with the acceptance methods
stated below.

South Portland, Maine Wafer Acceptance and Wafer Sort:

1.    Each lot will be sampled at PCM test prior to Wafer sort. The following
      minimum sample size will be tested and the Wafer will be rejected if the
      stated number, or more, of test sites on that Wafer fails a specified
      electrical parameter;

     Wafer Size      # Wafers per lot    # Sites per Wafer   Reject on # Sites
                                              Tested              Failing

      6 inch                  5                   5                   3
      5 inch                  5                   5                   3
      4 inch                  3                   5                   3

2.    In the event that one or more Wafers in the lot sample fail the above
      criteria, then 100% testing of the remaining Wafers in the lot will be
      performed and the above acceptance criteria applied to each Wafer.

3.    Electrical Test parameter distributions will be made available to National
      on a monthly basis.

Fairchild Wafer Fabrication and National Wafer Sort:

1.    A ten (10) Wafer lot sample will be tested to the applicable PCM
      specification prior to shipment to National Five (5) test sites per wafer
      will be sampled as the basis for electrical acceptance, and three (3) of
      those sites must pass the PCM test parameters. In the event that one or
      more sample wafers fails the PCM test, 100% testing of residual wafers
      will be performed and all Wafers which pass the PCM will be shipped to
      National.

2.    Individual PCM specifications (by Process) are defined in Exhibit F.

3.    Electrical Test parameter distributions will be made available on a
      monthly basis.
