<PAGE>

1.0   DEFINITIONS

      Unless otherwise provided herein, the terms listed below shall have the
      following meaning:

      1.1   "ABIC Process": Any of the wafer processes utilizing bipolar
            transistors having self-aligned poly silicon emitters in combination
            with the formation of a reacted layer of metal-silicide over the
            base and emitter in further combination with CMOS processes, as
            described in Exhibit 1.1.

      1.2   "Affiliate": Any Person controlling, controlled by, or under common
            control with a Party, whether directly or indirectly.

      1.3   "Assigned Patents": Patents or patent applications owned or
            controlled by National which cover a Business Product, as set forth
            in Exhibit 1.3.

      1.4   "Assigned Technology": Any and all National Intellectual Property
            assigned to Fairchild under this Agreement.

      1.5   "Assigned Trademarks": (i) U.S. trademarks owned or controlled by
            National which are set forth in Exhibit 1.5, (ii) trademarks, for
            any jurisdiction, owned or controlled by National that correspond to
            a trademark set forth in Exhibit 1.5 and (iii) any trademark rights,
            other than rights in the name Fairchild Research Center, that
            National has in the use of "Fairchild" or "Fairchild Semiconductor".

      1.6   "Best Efforts": Best Efforts require that the obligated party make a
            diligent, reasonable and good faith effort to accomplish the
            applicable objective. Such obligation, however, does not require any
            significant expenditure of funds or the incurrence of any
            significant liability on the part of the obligated party, nor the
            incurrence of any expense or liability which 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.

      1.7   "Business Product": A Logic Product, Memory Product or Discrete
            Product.

            data files that apply specifically to a Business Product.

      1.9   "Closing": the consummation of the transactions contemplated by the
            Purchase Agreement.

            interest, including associated goodwill, in Assigned Trademarks to
            Fairchild. National shall by the Closing Date execute and deliver to
            Fairchild all instruments necessary to execute and record the
            transfer of the Assigned Trademarks. National represents and
            warrants that to its Knowledge the U.S. trademarks set forth in
            Exhibit 1.5


                                        5
<PAGE>

            are free and clear of all liens, encumbrances and adverse claims and
            are free of all licenses to third parties except as set forth in
            Exhibit 2.1(a). At the Closing, National shall provide Fairchild
            with all of its files for each trademark registration or trademark
            registration application included under Assigned Trademarks.
            Fairchild assumes no obligation to prosecute, maintain, enforce or
            defend the Assigned Trademarks or to otherwise undertake any
            proceeding, judicial or otherwise, in reference to the Assigned
            Trademarks; provided, however, that if Fairchild determines to
            abandon any Assigned Trademark Fairchild shall give at least 90 days
            prior written notice to National and offer to assign such Assigned
            Trademark to National. National shall have notified Fairchild prior
            to the Closing Date of any judicial or administrative proceedings
            involving the Assigned Trademarks of which it has Knowledge
            including, but not limited to, (i) proceedings asserting
            infringement, invalidity or unenforceability and (ii) opposition,

            ownership of any rights in the name Fairchild Research Center.

                  (b) In a first transitional trademark license, subject to the
            terms of this Agreement, for any trademark owned or controlled by
            National that is not an Assigned Trademark but that is used in
            connection with a Business Product so as to be visible to customers
            without magnification (e.g., outside of the package), National
            hereby grants Fairchild a limited worldwide, paid-up, royalty-free,
            non-exclusive license under such trademarks to make, have made, use,
            offer for sale, promote, affix upon, import, package, sell or modify
            any Business Product. Fairchild shall have no right to sublicense
            such trademarks. This license under Section 2.1(b) is granted for
            transition purposes only and Fairchild agrees to use its Best
            Efforts to cease such use of National trademarks as soon as
            practicable, but not later than the second anniversary of the
            Closing Date.

                  (c) In a second transitional trademark license, subject to the
            terms of this Agreement, for any trademark owned or controlled by
            National that is not an Assigned Trademark but that is used in
            connection with a Business Product, National hereby grants Fairchild
            a limited worldwide, paid-up, royalty-free, non-exclusive license
            under such trademarks, limited to use of such trademark as embedded
            in Business Products, maskworks and Business Product-Specific
            Software, to design, develop, make, have made, use, offer for sale,
            promote, affix upon, import, package, sell or modify any Business
            Product. Fairchild shall have no right to sublicense such
            trademarks. This license under Section 2.1(c) is granted for
            transition purposes only and Fairchild agrees to use its Best
            Efforts to cease its own such use of National trademarks as soon as
            practicable, but not later than such time as the Business Product is
            discontinued or replaced with a redesigned version.

                  (d) In a third transitional trademark license, subject to the
            terms of this Agreement, for any trademark owned or controlled by
            National that is not an Assigned Trademark, National hereby grants
            Fairchild a limited worldwide, paid-up, royalty-free, non-exclusive
            license under such trademarks, limited to use of such trademark in
            customer specifications, drawings or similar documents

            referring to Business Products. This license under Section 2.1(d)
            includes a covenant by National not to sue Fairchild's customers for
            use of customer specifications, drawings or similar documents
            referring to Business Products that incorporate such National
            trademarks. The Parties acknowledge that it is in both of their
            interests to have such customer specifications, drawings or similar
            documents amended to remove, where commercially feasible, such
            National trademarks and replace them with corresponding Fairchild
            trademarks.

                  (e) Fairchild shall apply the trademarks licensed hereunder
            only in connection with Business Products manufactured in accordance
            with the standards of quality comparable to those employed by
            National prior to the Closing. With respect to Business Products
            associated with a trademark licensed hereunder, National shall have
            the right, not more often than annually, at reasonable times during
            normal business hours, and upon reasonable prior notice, to examine
            Business Products manufactured by Fairchild at Fairchild's
            facilities to confirm their compliance with the applicable standards
            of quality.

      2.2   PATENTS:

                  (a) Subject to the terms of this Agreement, including the
            exclusion set forth in this Section 2.2(a), National hereby grants
            to Fairchild a worldwide, paid-up, royalty-free, non-exclusive
            license under Licensed Patents to design, develop, make, have made,
            use, offer for sale, import, package, sell or modify any Business
            Product or Derivative Product for the life of the last to expire
            Licensed Patent. Fairchild shall have no right to sublicense
            Licensed Patents. This license to Fairchild excludes the right to
            use the ABIC Process. National assumes no obligation to prosecute,
            maintain, enforce or defend the Licensed Patents or to otherwise
            undertake any proceeding, judicial or otherwise, in reference to the
            Licensed Patents.

                  (b) National hereby assigns all its right, title and interest,
            including the right to sue for pre-Closing infringement, in Assigned
            Patents to Fairchild. National shall by the Closing Date execute and
            deliver, or cause to be executed and delivered by the inventor, to
            Fairchild all instruments necessary to execute and record the
            transfer of the Assigned Patents. National represents and warrants
            that to its Knowledge the Assigned Patents are free and clear of all
            liens, encumbrances and adverse claims and are free of all licenses
            to third parties except as set forth in Exhibit 2.2(b). For each
            Assigned Patent, National shall provide Fairchild, at the Closing,
            with all of its files (including without limitation the prosecution
            histories) or full and complete copies of such documents, at the
            Closing. Fairchild assumes no obligation to prosecute, maintain,
            enforce or defend the Assigned Patents or to otherwise undertake any
            proceeding, judicial or otherwise, in reference to the Assigned
            Patents. National has notified Fairchild prior to the Closing Date
            of any claims or judicial or administrative proceedings of which it
            has Knowledge involving the Assigned Patents including, but not
            limited to, (i) proceedings asserting infringement, invalidity, or
            unenforceability or (ii) opposition, nullification, interference,
            re-examination or reissue proceedings.

                  (c) Fairchild hereby grants to National a worldwide, paid-up,
            royalty-free, non-exclusive license under Assigned Patents for the
            life of the last to expire Assigned Patent. National shall have the
            right to grant sublicenses under its license to Assigned Patents
            solely to the extent necessary (i) for the operation of a joint
            venture in which National owns more than fifty percent (50%) of the
            controlling securities or other voting rights, (ii) for National to
            authorize third parties to second source National-designed products
            or (iii) for National to jointly develop products with third parties
            which are to be sold by National and/or a National development
            partner; provided, however, that nothing in this Section 2.2(c)
            shall be interpreted to modify National's obligations under the
            covenant not to compete set forth in Section 5.6 of the Purchase
            Agreement.

      2.3   MASKWORKS: Subject to the terms of this Agreement, National hereby

            while reserving an undivided interest for National. Neither
            Fairchild nor National shall have the right to sublicense any
            Co-owned Maskworks. In its use of the Co-owned Maskworks containing
            any National trademark, Fairchild's use of such a trademark shall be
            governed by Section 2.1(c); provided, however, that nothing in this
            Section 2.3 shall be interpreted to modify National's obligations
            under the covenant not to compete set forth in Section 5.6 of the
            Purchase Agreement, and provided further that National shall not
            license the right to use such Co-owned Maskworks in any manner

            hereby grants to Fairchild a perpetual worldwide, paid-up,
            royalty-free, non-exclusive license under Licensed Trade Secrets to
            design, develop, make, have made, use, offer for sale, import,
            package, sell or modify any Business Product or Derivative Product.
            Fairchild shall have no right to sublicense Licensed Trade Secrets.
            This license to Fairchild excludes the right to use the ABIC
            Process. Fairchild warrants that it will not use any National trade
            secret that is not licensed under this Agreement unless such trade
            secret information is obtained independently by rightful means.
            National shall not disclose Licensed Trade Secrets to a third party
            without imposing on the third party confidentiality provisions
            substantially the same as those set forth in Section 5.0.

      2.5   COPYRIGHTS: National hereby grants to Fairchild an undivided
            interest in the Co-owned Copyrights while reserving an undivided
            interest for National. In its use of copyrighted material containing
            a National trademark or reference to National, Fairchild's such use
            shall be governed by Section 2.1. Purchase of embedded test or
            equipment or other tools sold under the Purchase Agreement will
            include any license originally purchased therewith or purchased at a
            later date for use with such tools, equipment or embedded test. Such
            licenses shall be accounted for as an asset and will be transferred
            under the Purchase Agreement.

                  (d) Infringements or other breaches of Intellectual Property
            belonging to third parties that occurred prior to the Closing Date,
            and any damages arising therefrom, are the sole responsibility of

            National shall indemnify, save and hold harmless Fairchild, its

            directors, employees and agents from and against any and all damages
            arising out of any such claims of infringement.

                  (e) Fairchild agrees that upon its receipt of a claim giving
            rise to a claim for indemnity under Section 6.2(c), including,
            without limitation, receipt by it of any notification,
            communication, demand, assertion, claim, action, judicial
            proceeding, administrative proceeding, or other proceeding by any
            third party that Fairchild infringes or has misappropriated such a
            third party's Intellectual Property, Fairchild will give prompt
            written notice thereof to National.

                  (f) National's obligation to indemnify under Section 6.2(c)
            for claims of infringement of patents, patent applications,
            copyrights or maskworks or claims of misappropriation of trade
            secrets made by third parties is limited as follows:

                  (i)   with respect to Intellectual Property asserted against
                        Fairchild that is cross-licensed to National under
                        National's cross-license agreements existing on the
                        Closing Date, National shall indemnify for claims made
                        during a term of three (3) years after the Closing Date;
                        and

                  (ii)  with respect to all other Intellectual Property asserted
                        against Fairchild, National shall indemnify for claims
                        made during a term of two (2) years after the Closing
                        Date.

            For any claims for which National's obligation to indemnify is
            triggered during the respective indemnity term under Sections
            6.2(f)(i) or 6.2(f)(ii), National shall indemnify for the
            enforceable life of the asserted patent, patent subsequently issuing
            on a patent application having enforceable rights, maskwork,
            copyright or trade secret. On or before the Closing Date National
            shall provide Fairchild with a copy of each cross-license agreement
            that it has with a third party as of the Closing Date. Such
            cross-license agreements are listed in Exhibit 6.2(f) and shall be
            treated by Fairchild as National Confidential Information.

                  (g) National shall have the right, at its own cost and
            expense, to contest and defend by all appropriate legal proceedings
            any claim with respect to which it is called upon to indemnify
            Fairchild under the terms of this Section 6.2, and any such contest
            or defense may be conducted in the name and on behalf of Fairchild
            and/or National, as may be appropriate. Fairchild shall provide all
            reasonable information and assistance, at National's sole expense,
            as National may request, including, if commercially reasonable,
            redesigning Fairchild's products to make them non-infringing. The
            commercial reasonableness of a


                                       12
<PAGE>

            redesign of a product includes, without limitation, the retention of
            all performance features that materially affect the marketability of
            the product, the lack of any material affect on Fairchild's ability
            to obtain orders and to obtain and retain customers for the product,
            and the avoidance of any material increased manufacturing costs.
            National shall be permitted to settle such claims, upon reasonable
            prior notice to Fairchild, at its sole expense, provided Fairchild
            shall have no obligation for future expense or payment and provided
            that the settlement agreement shall not result in any requirement
            that Fairchild cease, alter (except for a redesign provided for by
            this Section 6.2(g)) or curtail the manufacturing, importation,
            marketing or sale of any product. Fairchild shall have the right,
            but not the obligation, to participate in such legal proceedings
            with counsel of its own selection and at its own expense. Fairchild
            agrees that National shall be authorized in the settlement of such
            claims to grant licenses under patents owned or controlled by
            Fairchild, provided that Fairchild receives from the licensee of
            such patents a reciprocal patent license of comparable weight and
            scope.

                  (h) Fairchild shall not solicit, directly or indirectly,
            claims or actions by Intellectual Property holders during the

            any indemnity hereunder to a counterclaim or similar action
            asserting infringement initiated by the third party after receiving
            Fairchild's claim. Disclosures made in accordance with Section 7.12
            (Publicity) shall not be deemed solicitations limited by this
            Section 6.2(h).

      7.3   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 conditions beyond the control
            of said Party, such as fire, flood, or other natural disaster, act
            of God, war, embargo, riot, labor dispute, 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.

      7.4   ASSIGNMENT: Neither this Agreement, nor any of its rights, interests
            or obligations, may be assigned by a Party without the prior written
            consent of the other Party; provided, however, that Fairchild may
            assign its rights hereunder as collateral security to any financial
            institution providing financing to consummate the transactions
            contemplated by the Purchase Agreement or any financial institution
            through which such financing is refunded, replaced or refinanced and
            any of the foregoing may assign Fairchild's rights hereunder in
            connection with a sale of FSC Semiconductor Corporation, Fairchild
            or the business in the form then being conducted by Fairchild
            substantially as an entirety. This Agreement shall be binding upon
            and inure to the benefit of and be enforceable by the successors and
            permitted assigns of each Party.

      7.5   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.

      7.6   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, and any litigation concerning this
            Agreement shall be brought within the courts located therein.

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

      7.8   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, unless the deletion of such
            provision shall cause this Agreement to become materially adverse to
            any Party, in which event the Parties shall use their respective
            Best Efforts to arrive at an accommodation which best preserves for
            the Parties the benefits and obligations of the offending provision.

            are for information purposes only and shall have no effect upon the
            intended purpose or interpretation of the provisions of this
            Agreement.

      7.11  INTEGRATION: This Agreement constitutes the entire agreement and
            understanding 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.

      7.12  PUBLICITY: Neither Party shall, without the approval of the other
            Party, 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 such 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

Side Letter") and the other Operating Agreements (as defined in Paragraph 7.1);
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

              hereunder.

      1.2     "Best Efforts" shall require that the obligated Party make a
              diligent, reasonable and good faith effort to accomplish the
              applicable objective. Such obligation, however, does not require
              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.

<PAGE>

              substantially the same specifications as any Product.

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
              during the first thirty-nine (39) fiscal periods of this Agreement
              the Parties are unable to resolve the problem, Fairchild shall
              continue to run the unmodified Process to supply Wafers pursuant
              to this Agreement. After the first 39 fiscal periods of this
              Agreement, if the Parties are unable to resolve the problem,
              Fairchild shall have the right to make such Process changes upon
              the provision of ninety (90) days prior written notice to
              National.

      3.3     Should Fairchild elect to discontinue a Process, it must give
              National written notice of no less than twenty-four (24) fiscal
              periods prior to the date it intends to discontinue any Process in
              the ABiC family and written notice of no less than twelve (12)
              fiscal periods for any other Process, or its future amended form.
              In no event, however may Fairchild discontinue any Process during
              the first thirty-nine (39) fiscal periods of this Agreement unless
              National agrees. 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.

              If Fairchild is unable to deliver Wafers due to a Process
              discontinuance during any ramp down phase occurring after the
              first 39 fiscal periods, then any ramp-down revenue obligations of
              National associated


                                      -5-
<PAGE>

              with Wafers to be manufactured under that Process will be 
              discharged in full.

      3.4     National shall have the right, in its sole discretion, to
              establish an alternative source of manufacturing for any Process.
              In support of any Process transfer required to establish such
              alternate source, Fairchild shall make available to National
              process characterization data, where such data exists at the time
              of such request, and all applicable manufacturing specifications,
              including run cards and complete unit process specifications for
              the Processes. In further support of such transfer, National may
              contract with Fairchild, at a cost to be negotiated, for up to
              thirteen (13) man weeks of engineering services. If such services
              are required away from the Facilities, National shall also pay
              reasonable travel and per diem expenses for the Fairchild
              engineers providing such services.

      3.5     There are currently a number of Processes under development at the
              Facilities. Attached as Exhibit C hereto is a listing of said
              Processes, the timetable and milestones to completion for each and
              the funding which National shall pay Fairchild for such
              development services. Fairchild will utilize its Best Efforts to
              complete all development work successfully in accordance with
              Exhibit C. National may terminate such development services prior
              to completion thereof only after three (3) months prior written
              notice to Fairchild. The rights of the Parties to any intellectual
              property resulting from such development work shall be governed by
              the terms of the Technology Transfer and License Agreement.

4.0   EXISTING PRODUCTS; SET UP AND QUALIFICATION OF NEW PRODUCTS; MODIFICATION
      OF EXISTING PRODUCTS

      4.1     For each new Product that National proposes to have 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.

      4.2     An initial data base for Mask generation or pattern generation, or
              acceptable production Masks will be 


                                      -6-
<PAGE>

              provided by National to Fairchild, per Fairchild specifications
              for large die, at National's expense, for each new Product to be
              fabricated for National. 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.

      4.3     As soon as practical following agreement on the items in Paragraph
              4.1 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.

      4.4     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
              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.

      4.5     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 


                                      -7-
<PAGE>

              order.

      4.6     If either National or Fairchild desires to make any changes to the
              final Specifications, Acceptance Criteria or Quality and
              Reliability Criteria for any existing 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.

      4.7     Fairchild may at its discretion declare a Product obsolete if such
              Product has not been run in production for a minimum of six (6)
              fiscal periods. Fairchild must provide National with twelve (12)
              months prior written notice of an obsolescence declaration and
              make reasonable provisions with National for a Last Time Buy for
              such Product. Within thirty (30) days after completing production
              of National's Last Time Buy, Fairchild shall return all data bases
              and Masks for such Product to National.

5.0   CAPACITY; VOLUME COMMITMENTS; PRODUCTION PLANNING

      5.1     All planning herein will be done under National's accounting
              calendar which currently divides its fiscal year into four (4)
              equal fiscal quarters, each of which consists of three (3) fiscal
              periods. The first two (2) periods of each quarter are of four (4)
              weeks in duration and the third period is of five (5) weeks
              duration.

      5.2     Two (2) weeks prior to the end of each National fiscal period
              National will provide in writing to Fairchild a baseline quantity
              of Wafers, set forth in terms of Wafer starts per Wafer Module,
              for the next eight (8) fiscal periods (the "Capacity Request").
              For the South Portland, Maine facility the Capacity Request shall
              clearly state each Wafer in terms of 6" Equivalent Wafers.
              Equivalency factors are set forth in Exhibit A. For the West
              Jordan, Utah facility the Capacity Request shall be stated in
              terms of the Process required to manufacture the Wafers.
              National's initial Capacity Request and Fairchild's


                                      -8-
<PAGE>

              Assured Capacity response formats are set forth in Exhibit D.

      5.3     Each fiscal period National may change the Capacity Request in
              accordance with the following table, provided that the maximum
              Capacity Request for each Wafer Module does not exceed National's
              share of each Wafer Module's installed equipment capacity as
              provided herein. Any changes outside those permitted under the
              following table must be by written agreement of the Parties.

               Fiscal Periods in
              the Capacity Request            Permitted Changes
              --------------------            -----------------

                    Period 1                        Fixed
                    Period 2                        +/-10%
                    Period 3                        +/-15%
                    Period 4                        +/-20%
                    Period 5                        +/-25%
                    Period 6                        +/-30%
                    Period 7                        +/-35%
                    Period 8                        +/-40%

      5.4     National's share of a Wafer Module's installed equipment capacity
              will equal the previous Fairchild Assured Capacity for that Wafer
              Module, plus that percentage of any excess capacity available in
              the Wafer Module equal to National's percentage of the currently
              utilized capacity in said Wafer Module. Installed equipment
              capacity by Wafer Module in South Portland, Maine is set forth
              below:

              Wafer Module                Annual Capacity
              ------------                ---------------

              FM Class 1   6"             133,000 Equivalent Wafer
                                            starts
              FM Class 100 4"             180,000 Wafer starts
                                            (6" equivalent)
              FM Class 100 5"             110,000 Wafer starts
                                            (6" equivalent)

              As no excess capacity exists in West Jordan, Utah, Fairchild
              hereby commits the following capacities to National for each
              National fiscal year:

                        FY 1998        19,400 Wafer starts
                        FY 1999         7,000 Wafer starts
                        FY 2000             0 Wafer starts


                                      -9-
<PAGE>

      5.5     One (1) work week after receipt of the Capacity Request, Fairchild
              shall provide National with a response to such Capacity Request,
              the "Fairchild Assured Capacity". The Fairchild Assured Capacity
              must guarantee the amount requested in National's latest Capacity
              Request, provided that any changes to National's latest Capacity
              Request are within the limits of Paragraph 5.3. Fairchild shall
              utilize its Best Efforts to comply with any requests by National
              for capacity above those which are permitted under Paragraph 5.3.
              In any case, Fairchild shall be obligated hereunder to provide
              National with the Wafer starts guaranteed in the Fairchild Assured
              Capacity response. The initial Fairchild Assured Capacity response
              will be the last one provided prior to the Effective Date. Set
              forth below are two examples of the foregoing:

              Example #1   The new Capacity Request is less than the last
                           Fairchild Assured Capacity response.

              next fiscal period are set forth in Exhibit D hereto.

6.0   PURCHASE ORDERS

      6.1     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 


                                      -10-
<PAGE>

              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 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 5, as the embodiment
              of the purchase order for specifying the Wafer quantity by Wafer
              Module and Process, and whether sorted or unsorted.

      6.2     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.

      6.3     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 


                                      -11-
<PAGE>

              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
              electronic data exchange, or other mutually satisfactory system.

      6.4     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.

      6.5     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
              twelve (12) or twenty-four (24) Wafers. For personalized ASIC
              Wafers drawn from mid-flow inventories, the smallest quantity that
              shall be ordered by National is three (3) Wafers, except for
              Wafers manufactured in the five-inch (5") fab, in which case the
              smallest quantity that can be ordered is six (6) Wafers.

7.0    PRICES AND PAYMENT

      7.1     The Parties hereby acknowledge that, as part of the collateral
              transactions contemplated under the Purchase Agreement and ongoing
              relationship between the Parties they have entered into the
              Revenue Side Letter under which National has agreed to provide a
              minimum revenue of [CONFIDENTIAL INFORMATION OMITTED AND FILED
              SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] periods
              after the Effective Date. National shall discharge its obligations
              under the Revenue Side Letter by purchasing goods and services
              under this Agreement, a corresponding Fairchild Assembly Services
              Agreement, and a Mil/Aero Wafer and Services Agreement of even
              date herewith (collectively the "Operating Agreements"). Set forth
              herein at Exhibit N is the forecasted volume of Wafers, by Wafer
              Module and Process, that National will purchase from Fairchild
              during the 


                                      -12-
<PAGE>

              aforementioned thirty-nine fiscal periods (the "Forecast
              Volumes"). The Forecast Volumes are for pricing purposes under
              this Section 7 only and may vary in magnitude and mix in practice,
              whereupon the prices applicable to the revised magnitude and mix
              may also vary. The Forecast Volumes will be reviewed and updated
              by the Parties every [CONFIDENTIAL INFORMATION OMITTED AND FILED
              SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] fiscal
              periods and shall be consistent with the principles of
              manufacturing set forth in Exhibit O.

      7.2     Set forth in Exhibit N hereto are the prices which National shall
              pay to Fairchild for Wafers manufactured hereunder during the
              first [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
              THE SECURITIES AND EXCHANGE COMMISSION] fiscal periods of this
              Agreement. The prices in Exhibit N for fiscal periods
              [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
              SECURITIES AND EXCHANGE COMMISSION] are for information purposes
              only and are based on the Parties' best estimate of projected
              volumes and costs. Set forth herein at Exhibit M is the forecast
              capacity utilization and associated fixed costs of the Fairchild
              FM 6001 six-inch fab by both National and Fairchild for the term
              of this Agreement.

      7.3     The prices which National shall pay to Fairchild for Wafers
              manufactured hereunder after the first [CONFIDENTIAL INFORMATION
              OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
              COMMISSION] periods of this Agreement shall be determined as set
              forth herein in Exhibit L. The pricing methodology to be followed
              hereunder will depend on the Wafer Module in which the Wafers are
              being manufactured. In addition, Products that qualify will be
              subject to a die cost adjustment as provided in Exhibit E.

      7.4     For purposes of Exhibit L, National, or any "Big 6" accounting
              firm designated by National, shall have reasonable rights to audit
              not more than twice each fiscal year the books and records of
              Fairchild relevant to the pricing terms of this Agreement in order
              to come to agreement with Fairchild with regard to Fairchild's
              actual manufacturing costs.

      7.5     Prices are quoted and shall be paid in U.S. Dollars. Such prices
              shall be on an FOB ship point basis. Payment terms are net thirty
              (30) from date 


                                      -13-
<PAGE>

              of invoice. Miscellaneous services may be invoiced separately.

      7.6     National shall pay, in addition to the prices quoted or invoiced,
              the amount of any freight, insurance, special handling and duties.
              National shall also pay all sales, use, excise or other similar
              tax applicable to the sale of goods or provision of services
              covered by this Agreement, or National shall supply Fairchild with
              an appropriate tax exemption certificate.

      7.7     National shall in no event be required to pay prices in excess of
              those charged by Fairchild for other third party foundry
              customers, for substantially similar products sold on
              substantially similar terms (e.g., volume, payment terms,
              manufacturing criteria, contractual commitments vs. spot buys,
              etc.). In the event Fairchild desires to perform such foundry
              services for other third party customers at such lower prices,
              Fairchild shall immediately notify National and National shall
              begin receiving the benefit of such lower price at the same time
              as such other third party customer. This Paragraph 7.7 shall not
              apply to the prices to be paid by National hereunder for the first
              twelve (12) fiscal periods of this Agreement, or if National fails
              to honor its fixed commitments under Section 5 and to the extent
              that such sales by Fairchild to third party foundry customers are
              only made in an attempt to make up for any underutilization of
              capacity thereby caused by National.

8.0   OTHER MANUFACTURING SERVICES

      8.1     At National's request, Fairchild will perform Wafer sort and test
              services based on sort and test programs prepared, owned and
              otherwise proprietary to National. Towards that end, National
              shall supply Fairchild with National-owned specific probe cards,
              load boards and test software in order that Fairchild may provide
              such services. Wafer sort shall be priced by hours of active
              sorting, with specific prices as set forth in Exhibit G, and
              specific sort times as set forth in Exhibit B.

      8.2     At National's request, Fairchild will perform separate epitaxial

              general principles set forth in Sections 5 and 6 above shall apply
              to such services, with epitaxial deposition services being treated
              as a separate Wafer Module with its respective Capacity Request
              and Fairchild Assured Capacity, but the lead time for epitaxial
              deposition shall be one (1) fiscal period. Prices shown in Exhibit
              N for Wafer foundry services include epitaxial deposition where
              appropriate. Otherwise, prices for such services are set forth in
              Exhibit G.

      8.3     At National's request, Fairchild shall continue to provide certain
              ongoing operational support services (the "Miscellaneous Support
              Services") to National at the same level of support that was in
              effect as of the Effective Date as listed in Exhibit J hereto
              consisting of: (i) those services which will be provided to
              National at no charge; and (ii) those services which will be
              provided at the prices set forth in Exhibit J on a purchase order
              basis. Operational support services not shown in Exhibit J will be
              provided on a purchase order basis at prices to be negotiated by
              the Parties case-by-case.

      8.4     In support of the Processes and those manufacturing processes
              listed in Exhibit C, Fairchild will make available design support

              Any additional requests are subject to fees set forth in Exhibit
              J.

9.0   DELIVERY; RESCHEDULING AND CANCELLATION

      9.1     Fairchild shall make reasonable and diligent efforts to deliver
              Wafers on the delivery dates specified in the Product delivery
              schedule provided by Fairchild pursuant to Paragraph 6.1. 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 or minus five
              percent (5%) of the quantity ordered.

      9.2     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 6.1, National
              shall have the right, subject to Paragraph 19.2, 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 19.2, in its 


                                      -16-
<PAGE>

              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.

      9.3     All Wafers delivered pursuant to the terms of this Agreement shall
              be suitable, 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 10.2 below.

      9.4     To facilitate the inspection of Product deliveries to National,
              lot integrity shall be maintained on all such deliveries, unless
              specifically waived by mutual agreement of the Parties.

      9.5     Subject to the provisions of Section 6, 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.

      9.6     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 


                                      -17-
<PAGE>

              additional expenses incurred. Sections 10, 11 and 12 of this
              Agreement shall not apply to Wafers stopped under this Paragraph
              9.6 for more than thirty (30) days, nor shall Fairchild make any
              commitments of yield with respect to such Wafers.

      9.7     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.

      9.8     As of 12:01 A.M. on the Effective Date, National will own all
              Wafers located at the Facilities which Fairchild has commenced
              processing but which have not yet been completed in accordance
              with the pertinent 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 10, 11 and 12 hereof
              shall specifically apply to all such Wafers.

10.0  QUALITY CONTROL AND INSPECTION; AND RELIABILITY

      10.1    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 


                                      -18-
<PAGE>

              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.

      10.2    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.

      10.3    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.

      10.4    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 Facilities 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 in writing by the Parties.

      10.5    Fairchild hereby warrants that the South Portland, Maine Facility
              currently is, and will remain 


                                      -19-
<PAGE>

              throughout the term of this Agreement, ISO9000 certified.
              Fairchild further warrants that the West Jordan, Utah Facility
              currently is, and will remain throughout the term of this
              Agreement, ISO9000 and AEC-100 certified.

11.0  MINIMUM YIELD ASSURANCES

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

      11.2    The baseline yield and initial MYA for each Product to be
              manufactured by Fairchild hereunder is set forth in Exhibit B
              hereto.

      11.3    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.

      11.4    For Products that qualify for die cost sharing, as provided in
              Exhibit E, the baseline Net Die Per Wafer (NDPW) for the Product
              will be used for defining the MYA. For all other Products, 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 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%.

      11.5    MYA will be determined as follows. For purposes of Wafers
              manufactured in South Portland, Maine, 


                                      -20-
<PAGE>

              Wafers which yield less than sixty (60%) percent of the mean will
              be considered discrepant and may be returned for full credit at
              National's discretion. For purposes of Wafers manufactured in West
              Jordan, Utah, Wafers which yield less than mean minus six sigma,
              as determined according to National Specification SS4908 in the
              version extant as of the Effective Date, 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.

      11.6    National shall provide yield analysis information on Wafers
              returned to Fairchild under this Section 11, in order to assist
              Fairchild in continuous Process improvement.

      11.7    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 Process related yield loss experienced by
              National and its customers.

12.0  WARRANTY

      12.1    Fairchild warrants that the Wafers 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 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, 


                                      -21-
<PAGE>

                     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.

      12.2    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.

13.0  ON-SITE INSPECTION AND INFORMATION

      13.1    Fairchild shall allow National and/or National's customers to
              visit and evaluate the Facilities 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.

      13.2    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; 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 


                                      -22-
<PAGE>

              of information.

14.0  PRODUCT ENGINEERING SUPPORT

      14.1    The Parties will cooperate in allowing National employees to have
              reasonable access to the Facilities 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 sixty (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 Facilities 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 Facilities or
              with applicable law.

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

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

15.0  TERM AND TERMINATION

      15.1    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 (8) fiscal periods prior to the
              end of such thirty-ninth (39th) fiscal period determine in good
              faith either an extension to this Agreement or 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 


                                      -23-
<PAGE>

              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 any such reduction.

      15.2    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.

      15.3    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 and/or complete any
              production ramp-down activity. Nothing in this Section 15 is
              intended to relieve either Party of any liability for any payment
              or other obligations 


                                      -24-
<PAGE>

              existing at the time of termination.

      15.4    The provisions of Sections 2, 12, 16, 17 and Paragraphs 19.5 and
              19.8 shall survive the termination of this Agreement for any
              reason.

16.0  EXPORT CONTROL

      16.1    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.

      16.2    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.

17.0  CONFIDENTIALITY

      17.1    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.

      17.2    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


                                      -25-
<PAGE>

              Agreement, 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.

      17.3    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.

      17.4    In the event that either Party 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 expense 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 


                                      -26-
<PAGE>

              process.

18.0  REPORTS AND COMMUNICATIONS

      18.1    Each Party hereby appoints a Program Manager whose
              responsibilities shall include acting as a focal point for the
              technical and commercial discussions between them related to the
              subject matter of this Agreement, to include monitoring within his
              or her respective company the distribution of Confidential
              Information received from the other Party and assisting in the
              prevention of the unauthorized disclosure of Confidential
              Information within the company and to third parties. The Program
              Managers shall also be responsible for maintaining pertinent
              records and arranging such conferences, visits, reports and other
              communications as are necessary to fulfill the terms and
              conditions of this Agreement. The names, addresses and telephone
              numbers of the Program Managers will be communicated between the
              Parties from time to time.

19.0  GENERAL

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

      19.2    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.

      19.3    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 


                                      -27-
<PAGE>

              ordinary course providing financing to consummate the transactions
              contemplated by the Purchase Agreement or any bona fide financial
              institution engaged in 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.

      19.4    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.

      19.5    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.

      19.6    WAIVER: Should either of the Parties fail to exercise or enforce
              any provision of this Agreement such failure 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.

      19.7    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.

      19.8    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

      The following processes, upon which development is underway, will be
      regarded as complete when qualification is achieved to Class III, as
      defined in National specification SOP-5-032 RA. Additional funding will be
      required from National if programs are not completed due to National's
      failure to perform its responsibilities by the Scheduled End of Work date.

                                    EXHIBIT E

                             DIE COST IMPACT SHARING

1.0   GENERAL

      1.1   National and Fairchild will implement 50:50 sharing of yield gain
            and loss implemented in accordance with the principles set forth in
            this Exhibit.

      1.2   The yield adjustment amount will be calculated at the end of the
            first six (6) fiscal periods ("Fiscal Half") from the Effective Date
            and each Fiscal Half thereafter, retroactively. National will pay
            Fairchild a yield premium fee in the case of average yield
            improvement; Fairchild will reimburse National in the case of
            average yield degradation.

      1.3   Net Die Per Wafer (NDPW) will be used as the basis for the
            calculation.

2.0   ESTABLISHING YIELD BASELINE

      2.1   In order to qualify for die cost sharing, Products must (i) have
            achieved a minimum production volume of at least ninety-six (96)
            Wafers (i.e., the equivalent of at least four (4) 24-Wafer or eight
            12-Wafer lots) per period for three (3) of the preceding six (6)
            fiscal periods (a minimum of 288 Wafers) and (ii) have a stable
            yield history (e.g., without known yield or test sensitivities). The
            baseline NDPW of each qualifying Product as of the Effective Date
            shall be the average NDPW for the preceding six (6) fiscal periods.
            Baseline NDPWs will be reset twelve (12) fiscal periods ("Fiscal
            Year") after the Effective Date and at the end of each Fiscal Year
            thereafter.

      2.2   A baseline NDPW will be established for a new Product after the
            Product has achieved a minimum production volume of at least 96
            Wafers per fiscal period (i.e., the equivalent of at least four (4)
            24-Wafer or eight 12-Wafer lots) for three (3) of the preceding six
            (6) fiscal periods (a minimum of 288 Wafers) and (ii) has
            established a stable yield history (e.g., without known yield or
            test sensitivities). Once a baseline NDPW has been established for a
            Product and mutually agreed upon by the Parties, such baseline NDPW
            will remain in effect until the next Fiscal Year reset point.

      2.3   In case of a change in the sort program which affects the yield, a
            new baseline NDPW will be mutually agreed upon based on the effect
            of the change on the Product yield. The new baseline will apply to
            all lots measured after the change has been implemented.

      2.4   In the case of a Mask change which affects the yield, a new baseline
            NDPW will be established as provided in Paragraph 2.2 of this
            Exhibit.

      2.5   For Products that are not sorted by Fairchild the Parties will agree
            on procedures to assure that production sort programs cannot be
            changed without Fairchild's acknowledgment, and the provisions of
            Paragraph 2.3 of this Exhibit shall apply to any such changes.

      2.6   In order for a Product that is not sorted by Fairchild to qualify
            for die cost sharing, National must make wafer sort and yield data,
            and wafers (at Fairchild's cost) as required for analysis, available
            to Fairchild on a timely basis and in conformance with Fairchild's
            own internal requirements for such data.

3.0   CALCULATIONS

      3.1   At the end of each Fiscal Half, a Product list to be used for the
            yield adjustment calculation will be mutually agreed by the Parties.
            Each Product in this list shall (i) have an established baseline
            NDPW; (ii) have achieved a minimum production volume of at least
            ninety-six (96) Wafers per period (i.e., the equivalent of four
            24-Wafer or eight 12-Wafer lots) for three (3) of the preceding six
            (6) fiscal periods (a minimum of 288 Wafers); and (iii) have
            established a stable yield history (e.g., without known yield or
            test sensitivities).

      3.2   The percent change in NDPW for the preceding Fiscal Half will be
            calculated for each qualifying Product based on the difference
            between the baseline and actual NDPW for the Product;

      3.3   The semiannual adjustment for die cost sharing will equal:

            (Base Wafer Price) X (NDPW Percent Change) X (0.5) X (Wafers
            Shipped)

      3.4   The total adjustment will be the sum of the adjustments of the
            qualifying Products.

      3.5   Fairchild will perform the die cost sharing calculation and provide
            an accounting to National following the end of each Fiscal Half
            together with an invoice or a credit for the die cost adjustment
            amount.

4.0   OTHER

      4.1   MYA will be used in conjunction with die cost sharing for purposes
            of identifying "Maverick" wafers that will be discarded (unless
            National agrees to accept). For Products that qualify for die cost
            sharing, the baseline NDPW will be used as the basis for defining
            the MYA for the Product.

      4.2   Wafer price adjustments to reflect changes in Fairchild's
            manufacturing cost base are independent of die cost sharing.

      4.3   Products manufactured under the Mil/Aero Wafer and Services
            Agreement between the Parties of even date herewith shall not
            qualify for die cost sharing.

                                    EXHIBIT F

                            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 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 tests, 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.

Sort Operating Principles

FAIRCHILD will load the South Portland, Maine, West Jordan, Utah and Penang,
Malaysia Wafer Sort facilities in a manner that minimizes the total costs to
NATIONAL, while generating the best possible yield control for NATIONAL
Products. This means that Penang will be the primary sorting site for those
Products which can be sorted there, unless otherwise instructed by NATIONAL.

on a case by case basis, FAIRCHILD will provide NATIONAL the opportunity to
install NATIONAL's automatic test equipment within FAIRCHILD's Facilities, which
might be required to take advantage of FAIRCHILD's Integrated Yield Management
services. FAIRCHILD will quote hourly rates for operations, maintenance and
support services, and NATIONAL will assume the costs of equipment depreciation,
spare parts, initial setup, probe cards, and electrical interface boards.

New sort hardware setups or Wafer sort for new Products

In the case of new hardware setups or Wafer sort for new Products, if the
hardware and/or test program is provided by National, Fairchild will connect the
hardware and/or test program and attempt to sort wafers. If engineering problems
are found then Fairchild will debug and solve the problems to the extent of its
capabilities utilizing Best Efforts.

                                    EXHIBIT L

1.    Prices for Wafers manufactured in the six-inch fab in South Portland,
      Maine will be determined as follows. Shortly prior to the conclusion of
      the first six (6) fiscal periods under this Agreement ("Fiscal Half"), the
      Parties shall meet in order to determine new prices for the Second Fiscal
      Half. At that meeting the Parties will review the manufacturing history
      during such part of the First Fiscal Half for which such information shall
      be available in order to determine Fairchild's actual manufacturing cost
      base for that Wafer Module which shall be consistent with National's
      standard cost accounting practices in effect as of the Effective Date,
      (the "Class 1 Reference Cost Base"). If the Class 1 Reference Cost Base
      plus a twenty-five percent (25%) markup, is less than the price applicable
      for the first Fiscal Half, prices for the second Fiscal Half will be equal
      to the Class 1 Reference Cost Base plus a twenty-five percent (25%)
      markup. If Fairchild's actual costs have increased, the prices will remain
      the same. Exhibit N sets forth the prices for Wafers to be manufactured in
      the South Portland, Maine six-inch fab during the next twenty-seven (27)
      fiscal periods of this Agreement based on the forecast volumes. For
      different volumes, the prices may vary as set forth in the Revenue Side
      Letter.

2.    Prices for Wafers manufactured on the four and five-inch fabs in South
      Portland, Maine and the West Jordan, Utah fab will be determined as
      follows. Shortly prior to the conclusion of the first Fiscal Half, the
      Parties shall meet in order to determine new prices for each of the
      aforementioned Wafer Modules for the second Fiscal Half. At that meeting
      the Parties will review the manufacturing history during such part of the
      first Fiscal Half for which such information shall be available in order
      to determine each Wafer Module's actual manufacturing cost base which
      shall be consistent with National's standard cost accounting practices in
      effect as of the Effective Date, (the "Reference Cost Base" per applicable
      Wafer Module). For each Wafer Module, if the Reference Cost Base plus a
      twenty-five percent (25%) markup is less than the price applicable for the
      first Fiscal Half, prices for the second Fiscal Half for that Wafer Module
      will be equal to its Reference Cost Base plus a twenty-five percent (25%)
      markup. If Fairchild's actual costs have increased, the prices for Wafers
      manufactured in that Wafer Module will remain the same as during the first
      Fiscal Half.

      The applicable Reference Cost Base and second Fiscal Half prices will
      remain in effect for each of the aforementioned Wafer Modules for the
      remaining term of this Agreement. Shortly prior to the conclusion of the
      eighteenth (18th) fiscal period of this Agreement, and every six (6)
      fiscal periods thereafter, the Parties shall meet in order to determine
      Fairchild's actual manufacturing costs for the preceding Fiscal Half which
      shall be consistent with National's standard cost accounting practices in
      effect as of the Effective Date. If a Wafer Module's actual costs during
      the previous Fiscal Half were lower than its Reference Cost Base, the
      Parties shall calculate what National would have paid if such actual costs
      had been used in originally setting the prices, rather than the applicable
      Reference Cost Base. Fairchild shall give National a credit equal to fifty
      percent (50%) of the savings National would have realized if it had paid
      the recalculated prices. No monies will be owing to or from National or to
      or from Fairchild if Fairchild's actual costs during 
<PAGE>

      the preceding Fiscal Half were higher than the applicable Reference Cost
      Base.

3.    The prices for any Wafers or Equivalent Wafers purchased during a National
      fiscal year in excess of the Forecast Volumes are set forth in Exhibit N.

4.    If National does not place orders for Wafers or Equivalent Wafers in
      accordance with the Forecast Volumes during any National fiscal year, the
      provisions of the Revenue Side Letter will apply with respect to the
      manner in which National will discharge its commitment to Fairchild for
      that fiscal year.

5.    Pricing for any extension and/or ramp-down period beyond the first
      thirty-nine (39) fiscal periods of this Agreement will be negotiated in
      good faith by the Parties.

                           PRINCIPLES OF MANUFACTURING

(Degree) Forecasted volumes will be supplied covering all aspects of activity
         for 3 years.

(Degree) National will meet a Revenue commitment of $330m over 3 years and 3
         months, effective the day of closing of the purchase agreement.

(Degree) Price will be fixed for the first 6 months. Pricing will reflect
         National's full absorption of the fixed cost based on its percent
         utilization of the South Portland, Maine 6" facility (i.e., this
         incorporates the agreed equivalency factors).

(Degree) Principles will be set to establish pricing for the second 6 months.

(Degree) Cost base for FM Class 1 will be Q4 Forecast FY97 with a fully 
         capitalized base.

(Degree) National will pay a mark up of 25% in the first 12 months.

(Degree) For Class 1 the pricing after the initial 12 months is targeted to
         decline 12% or better given equal loadings in each subsequent interval.
         If the volume is greater price reduction will be increased accordingly.

(Degree) Incremental volumes above the forecast volumes will be priced per
         table:

            4"           =   $ 70
            5"           =   $110
            6" ABIC          $825
            CBTX             $635
            CBI              $705
            CS80             $500

(Degree) Available incremental capacity will be at the same rate as the base.

(Degree) Pricing activity beyond Fiscal Year 00

         -  In case the Parties are unable to agree on prices for the following
            year, the prices used in the previous year will remain in effect,
            and the Parties will be allowed to reduce the capacity commitment
            each quarter by a quantity of 20%, starting one quarter after the
            price agreements expire. A notice shall be given 90 days prior to
            any capacity reduction.

(Degree) For the Class 100 and the Penang Assembly and Test Facilities the price
         after the initial 12 months commitment will be at cost plus 25%. If the
         actual cost is better than the agreed upon base a credit will be given
         to National in the subsequent Fiscal Half equal to 50% of the savings.
         If the cost is greater than the agreed upon base, the price will be at
         the agreed upon base.

CONFIDENTIAL PORTIONS OF THIS DOCUMENT HAVE BEEN DELETED AND FILED SEPARATELY

CONFIDENTIAL TREATMENT

March 11, 1997


Fairchild Semiconductor Corporation
333 Western Avenue
South Portland, ME  04106
Attn: Mr. Kirk P. Pond
      President and CEO

Re:   Asset Purchase Agreement, dated March 11, 1997, by and between National
      Semiconductor Corporation ("National") and Fairchild Semiconductor
      Corporation ("Fairchild")

Gentlemen and Ladies:

      This will confirm our agreement that during the first [CONFIDENTIAL
INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION] months following the close of the above-referenced Asset Purchase
Agreement, National shall purchase from Fairchild a minimum of [CONFIDENTIAL
INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION] in goods and services (the "Revenue Commitment") under the following
agreements to be entered into by National and Fairchild at the close of the
Asset Purchase Agreement: the Foundry Services Agreement, Assembly Services
Agreement and Mil/Aero Wafer and Services Agreement (collectively, the
"Operating Agreements").

      To assure Fairchild of a consistent revenue stream, National agrees that
it will manage the Revenue Commitment by purchasing from Fairchild goods and
services in at least the amounts of [CONFIDENTIAL INFORMATION OMITTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] in Fiscal Year
[CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION], [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION] in fiscal year [CONFIDENTIAL
INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION] and [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION] in Fiscal Year [CONFIDENTIAL INFORMATION
OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION]. While
purchases for the purchases for the remaining [CONFIDENTIAL INFORMATION OMITTED
AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] of the Revenue
Commitment may be made by National at any time during the [CONFIDENTIAL
INFORMATION OMITTED AND FILED SEPARATELY WITH 
<PAGE>

THE SECURITIES AND EXCHANGE COMMISSION] period, National shall work with
Fairchild to avoid bottlenecks in Fairchild's capacity. National and Fairchild
will periodically review the forecasts submitted under the Operating Agreements
in order to ensure that National is on schedule to satisfy both its annual
minimum revenue guarantee and its obligations under the Revenue Commitment as a
whole. If those forecasts indicate that National will not meet such obligations,
the parties shall meet to adjust the volumes and/or pricing in one or more of
the Operating Agreements until such obligations are satisfied. If the parties
cannot reach agreement on such adjustments, National shall pay Fairchild a sum
equal to the shortfall in the profit that Fairchild would have earned and the
fixed costs that it would have recovered if National had purchased sufficient
goods and services sufficient to satisfy the minimum annual revenue guarantee,
or as the case may be, the Revenue Commitment as a whole.

      One year after the close of the Asset Purchase Agreement, and every six
(6) months thereafter, the parties will meet to review Fairchild's recovery of
the fixed costs of its FM 6001 6-inch fab. Exhibit M of the Foundry Services
Agreement lists that portion of those fixed costs which National is expected to
cover by means of purchases thereunder. If such purchases are insufficient to
cover National's share of those costs for any fiscal year, National may credit
against the shortfall the fixed cost coverage of purchases made during that
fiscal year in excess of forecast volumes for Fairchild's other wafer fabs
and/or under the other Operating Agreements, it being understood that Fairchild
is obligated to provide capacity to National only as set forth in the Operating
Agreements. Should such additional purchases during that fiscal year be
insufficient to cover National's share of the fixed costs, National shall pay
Fairchild a sum equal to such remaining shortfall promptly after the end of the
fiscal year. Notwithstanding the foregoing, National shall not be required to
make up any shortfall to the extent that Fairchild's own use of the FM 6001 fab
is greater than that set forth in Exhibit M of the Foundry Services Agreement.

      National will be relieved of its obligations hereunder to the extent it is
unable to meet the Revenue Commitment as a result of Fairchild's inability to
provide National with capacity as guaranteed under the Operating Agreements,
provided National has complied with the forecast and order requirements of such
Operating Agreements.

Agreement.

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

1.0   DEFINITIONS

      1.1   "Best Efforts" shall require that the obligated Party make a
            diligent, reasonable and good faith effort to accomplish the
            applicable objective. Such obligation, however, does not require 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.

      3.5   Fairchild hereby agrees to verify the Die count and advise National
            of any variance greater than one percent (1%).

      3.6   National will provide Fairchild with a "Lot Traveler" in a format
            identical to that in effect on the Effective Date and outlined in
            Exhibit A hereto for the first six (6) months after the Effective
            Date. After that period of time, Fairchild may utilize its own
            Traveler, provided its form has previously been approved in writing
            by National, which approval shall not be unreasonably withheld.

      3.7   Fairchild shall provide National with the following manufacturing
            data in a format and pursuant to criteria and procedures agreed to
            by the parties, on a monthly basis:

            (a)   WIP from sealing through final assembly, including finished

            enclosed for each assembly lot (kit). Future traceability for a lot
            (kit) shall be based solely on the run card and shall be the
            responsibility of National. The assembly run card shall show the
            yield for each yield point in the assembly process. By mutual
            agreement of the Parties, traceability may instead be software
            based, so long as such records are accessible to both Parties.

4.0   PACKAGE/PROCESS CHANGES NOTIFICATION


                                      -5-
<PAGE>

      4.1   If Fairchild proposes to make any change affecting the assembly
            processes, materials and/or suppliers, to include, but not be
            limited to, lead frame design, lead frame material, die attach
            material, wire bond material, molding compound, lead plating process
            or plating material, test programs or assembly procedures affecting
            the Devices, Fairchild will notify National of the intended change
            in accordance with Fairchild's change procedures then in effect. If
            the proposed change is unacceptable to National, National and
            Fairchild shall work together in efforts to resolve the problem. If
            during the first thirty-nine (39) fiscal periods of this Agreement
            the Parties are unable to resolve the problem, Fairchild shall not
            make the proposed change. After the first 39 fiscal periods of this
            Agreement, if the Parties are unable to resolve the problem,
            Fairchild shall have the right to make such change upon the
            provision of ninety (90) days prior written notice to National.
            Notwithstanding the foregoing, however, Fairchild shall in no event
            manufacture Devices other than in strict accordance with the
            Specifications, or any amendments thereto, without the prior written
            consent of National.

      4.2   National shall provide at least fifteen (15) days prior written
            notice to Fairchild of any proposed change in Die design, layout
            modification, fabrication process, test programs or other changes
            which may impact upon Fairchild's processing, handling or assembly
            of Devices. Fairchild shall not be responsible for any assembly or
            test loss incurred as a result of National's failure to provide
            timely notification of such change.

      4.3   National reserves the right to make changes to the Specifications
            that reflect improvements, developments or other technically desired
            changes in the Devices. National shall notify Fairchild of such
            requested change orders and Fairchild shall respond within thirty
            (30) working days regarding the feasibility, schedule and
            anticipated costs of implementing such change orders. Once the
            Parties have agreed in writing to the engineering changes, schedule
            and prices thereof, Fairchild shall promptly take all measures
            required to incorporate such change orders into the Devices.
            Fairchild shall have the right to renegotiate the price and/or 


                                      -6-
<PAGE>

            its capacity commitments hereunder if such changes will have an
            adverse effect on Fairchild's assembly or test capacity.

5.0   DEVICE ACCEPTANCE/QUALIFICATION/RAMP UP

      5.1   Should Fairchild agree to add new package types requested by
            National, Fairchild shall utilize its Best Efforts to complete
            qualification assembly of new package types as soon as possible,
            including qualification lots. National shall reimburse Fairchild for
            the full costs of equipment, tooling and one time start up costs
            required to manufacture new packages that Fairchild will exclusively
            use for National, otherwise such costs will be shared.

      5.2   National shall be responsible for specifying and performing any
            qualification testing deemed necessary.

      5.3   Fairchild reserves the right to refuse assembly of any new Devices
            which violate Fairchild internal design or processing requirements
            that are introduced after the Effective Date.

      5.4   Fairchild shall provide National with a preliminary ramp-up
            schedule, which may be subject to subsequent reduction by Fairchild
            in the event unforeseen problems are encountered by Fairchild with
            yields, process, capacity support, quality/reliability or other
            product or process features. Fairchild shall immediately notify
            National in writing of the necessity of any such reductions.

6.0   INSPECTION, ACCEPTANCE AND WARRANTY

      6.1   For those Devices not tested by Fairchild, National shall conduct
            incoming acceptance tests within ten (10) days after delivery at its
            test facility. Upon completion of such tests, National shall
            promptly report any shortage, damage or defective Devices in any
            shipment. In the case of defective Devices found by National to
            exceed applicable AQL and/or PPM Limits in effect as of the
            Effective Date, or as subsequently agreed in writing by the Parties,
            National shall promptly ship samples of defective 


                                      -7-
<PAGE>

            Devices to Fairchild for verification. If such testing demonstrates
            that the shipment failed to meet the relevant Specifications due to
            Fairchild workmanship or materials, National may at its option
            either:

            (a)   deduct the defective Devices' purchase price from Fairchild's
                  invoice, in which event National shall, if requested by
                  Fairchild, return to Fairchild the damaged or defective
                  Devices at Fairchild's risk and expense,

            (b)   return the damaged or defective Devices to Fairchild, at
                  Fairchild's risk and expense, for credit, or

            (c)   scrap the defective Devices at Fairchild's request for credit.

      6.2   Fairchild warrants that the services provided to National hereunder
            shall conform to all applicable Specifications for assembly and/or
            test and shall be free from defects in material and Fairchild's
            workmanship. Such warranty, however, shall not apply to the design
            or operation of the National supplied Die incorporated in the
            Devices. This warranty is limited to a period of one (1) year from
            the date of delivery to National. If, during the one year period:

            (i)   Fairchild is notified promptly upon discovery in writing by a
                  detailed description of any such defect in any Device; and

            (ii)  National receives a return material authorization number from
                  Fairchild and returns such Device to the applicable Facility
                  at National's expense for inspection; and

            (iii) Fairchild's examination reveals that the Device is indeed
                  defective and does not meet the applicable Specification 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


                                      -8-
<PAGE>

                  then, within a reasonable time, Fairchild shall credit
                  National for such defective Device. Fairchild shall reimburse
                  National for the transportation charges paid by National in
                  returning such defective Devices to Fairchild. The performance
                  of this warranty shall not act to extend the one (1) year
                  warranty period for any Device(s) repaired or replaced beyond
                  that period applicable to such Devices(s) as originally
                  delivered.

      6.3   THE FOREGOING WARRANTY CONSTITUTES FAIRCHILD'S EXCLUSIVE LIABILITY,
            AND NATIONAL'S EXCLUSIVE REMEDY, FOR ANY BREACH OF WARRANTY.
            FAIRCHILD MAKES AND NATIONAL RECEIVES NO WARRANTIES OR CONDITIONS ON
            THE SERVICES PERFORMED HEREUNDER, EXPRESS, IMPLIED, STATUTORY OR
            OTHERWISE, AND FAIRCHILD SPECIFICALLY DISCLAIMS ANY WARRANTY OF
            MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

7.0   CAPACITY; VOLUME COMMITMENTS; PRODUCTION PLANNING

      7.1   All planning herein will be done under National's accounting
            calendar which currently divides its fiscal year into four (4) equal
            fiscal quarters, each of which consists of three (3) fiscal periods.
            The first two (2) periods of each quarter are of four (4) weeks in
            duration and the third period is of (5) weeks duration.

      7.2   Two (2) weeks prior to the end of each National fiscal period, or as
            otherwise agreed by the Parties, National will provide to Fairchild
            a baseline quantity of assembly starts, set forth in terms of
            product family, package and pin count, for the next eight (8) fiscal
            periods (the "Capacity Request"). National's initial Capacity
            Request and Fairchild's Assured Capacity response formats are set
            forth herein at Exhibit B.

      7.3   Each fiscal period, National may make changes to the Capacity
            Request in accordance with the following table, provided that the
            maximum Capacity Request for each package and pin count module does
            not exceed National's share of each package and pin count module's
            installed equipment capacity. Any changes outside those permitted
            under the following table must be by mutual consent of the Parties.

                  Period 8                                +/-40%

      7.4   National's share of a package and pin count module's installed
            equipment capacity will equal the previous Fairchild Assured
            Capacity for that module, plus that percentage of any excess
            capacity available in the package and pin count module equal to
            National's percentage of the currently utilized capacity in said
            module. Installed equipment capacity by package and pin count module
            is set forth herein at Exhibit C.

      7.5   One (1) work week after receipt of the Capacity Request, Fairchild
            shall provide National with a response to such Capacity Request, the
            "Fairchild Assured Capacity". The Fairchild Assured Capacity must
            guarantee the amount requested in National's latest Capacity
            Request, provided that any changes to National's latest Capacity
            Request are within the limits of Paragraph 7.3. Fairchild shall
            utilize its Best Efforts to comply with any requests by National for
            capacity above those which are permitted under Paragraph 7.3. In any
            case, Fairchild shall be obligated hereunder to provide National
            with the assembly starts guaranteed in the Fairchild Assured
            Capacity response. The initial Fairchild Assured Capacity response
            shall be the last response provided prior to the Effective Date. Set
            forth below are two examples of the foregoing:

            period are set forth in Exhibit D hereto.

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 assembly starts three (3) fiscal periods in the future. They
            shall state the product family, package and pin count, 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 assembly
            starts request for the next fiscal period, Fairchild shall provide
            National with a Device delivery schedule either on a weekly basis as
            assembly is started or for the assembly 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 assembly starts
            by package and pin count.

      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 


                                      -11-
<PAGE>

            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 assembled 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 package and pin count to be used. A change
            that will negatively impact loading or alter the package and pin
            count 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 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 Device 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 shall be a 50%
            reduction of standard cycle time with a $2000.00 lot charge.

      8.5   Fairchild may manufacture lots of any size which satisfy the
            requirements of effective manufacturing. However, National must
            place order for full 


                                      -12-
<PAGE>

            flow and prototype products in minimum lot sizes of three thousand
            (3,000) Devices.

9.0   PRICING AND PAYMENT

      9.1   The Parties hereby acknowledge that, as part of the collateral
            transactions contemplated under the Purchase Agreement and ongoing
            relationship between the Parties, they have entered into the Revenue
            Side Letter under which National agrees to provide a minimum revenue
            of Three Hundred Thirty Million Dollars ($330,000,000.00) to
            Fairchild during the first thirty-nine (39) fiscal periods after the
            Effective Date. National shall discharge its obligations under the
            Revenue Side Letter by purchasing goods and services under this
            Agreement, a corresponding Fairchild Foundry Services Agreement, and
            a Mil/Aero Wafer and Services Agreement of even date herewith
            (collectively the "Operating Agreements"). Set forth herein at
            Exhibit G is the forecasted volume of assembly services that
            National will purchase from Fairchild during the aforementioned
            thirty-nine fiscal periods (the "Forecast Volumes"). The Forecast
            Volumes are for pricing purposes under this Section 9 only and may
            vary in magnitude and mix in practice, whereupon the prices
            applicable to the revised magnitude and mix may also vary. The
            Forecast Volumes will be reviewed and updated by the Parties every
            fiscal period and shall be consistent with the principles of
            manufacturing set forth in Exhibit H.

      9.2   Set forth in Exhibit G hereto are the prices which National shall
            pay to Fairchild for backgrind, standard assembly and test services
            hereunder during the first six (6) fiscal periods of this Agreement.
            The prices in Exhibit G for fiscal periods 7 through 39 are for
            information purposes only and are based on the Parties' best
            estimate of forecast volumes and projected costs.

      9.3   The prices which National shall pay to Fairchild for background,
            standard assembly and test services hereunder after the first six
            (6) fiscal periods of this Agreement are set forth herein as 


                                      -13-
<PAGE>

            Exhibit K. The pricing methodology to be followed hereafter will
            depend on the Facility at which the services will be provided.

      9.4   For purposes of Exhibit K, National, or any "Big 6" accounting firm
            designated by National, shall have reasonable rights to audit not
            more than twice each fiscal year the books and records of Fairchild
            relevant to the pricing terms of this Agreement in order to come to
            agreement with Fairchild with regard to Fairchild's actual
            manufacturing costs.

      9.5   Prices are quoted and shall be paid in U.S. Dollars. Such prices are
            on an FOB ship point basis. Payment terms are net thirty (30) from
            date of invoice. Miscellaneous services may be invoiced separately.

      9.6   National shall pay, in addition to the prices quoted or invoiced,
            the amount of any freight, insurance, special handling and duties.
            National shall also pay all sales, use, excise or other similar tax
            applicable to the sale of goods or provision of services covered by
            this Agreement, or National shall supply Fairchild with an
            appropriate tax exemption certificate.

      9.7   Quoted prices are based on the use of standard Fairchild processes
            and on the assumption that National's product is readily
            accommodated by Fairchild's assembly/handling equipment and
            processes. Any changes that must be made thereto shall result in
            additional charges to National that are mutually agreed to by the
            Parties.

      9.8   Unless otherwise noted, quoted prices for assembly shall include
            packing, marking and testing in accordance with the Specifications
            for Devices that are in production as of the Effective Date. For new
            Devices added after the Effective Date, pricing will reflect
            specifications and any special requirements for the Devices such as
            multi-insertion testing.

      9.9   Should yields below historical levels be directly attributable to
            Die, materials, processes or documentation provided by National,
            then National 


                                      -14-
<PAGE>

            shall be charged for the full price of Devices begun in assembly,
            including handling, incurred by Fairchild in processing such units.

      9.10  Should National terminate any order prior to process completion,
            National shall be charged a prorated portion of the full price of
            such Device subject to a negotiated adjustment, based on the process
            termination point, including handling incurred by Fairchild in
            processing the total quantity started in assembly.

      9.11  Fairchild may invoice National for complete or partial lots (kits).

      9.12  National shall in no event be required to pay prices in excess of
            those charged by Fairchild for other third party customers, for
            substantially similar services sold on substantially similar terms
            (e.g., volume, payment terms, manufacturing criteria, contractual
            commitments vs. spot buys, etc.). In the event Fairchild desires to
            perform such services for other third party customers at such lower
            prices, Fairchild shall immediately notify National and National
            shall begin receiving the benefit of such lower price at the same
            time as such other third party customer. This Paragraph 9.12 shall
            not apply to the prices to be paid by National hereunder for the
            first twelve (12) fiscal periods of this Agreement, or if National
            fails to honor its fixed commitments under Section 7 and to the
            extent that such sales by Fairchild to third party customers are
            only made in an attempt to make up for any underutilization of
            capacity thereby caused by National.

      9.13  For assembly and test services not reflected in Exhibit G, terms
            shall be on an individual purchase order basis at prices to be
            negotiated by the Parties using a methodology based on that set
            forth in Exhibit K.

10.0  DELIVERY; RESCHEDULING AND CANCELLATION

      10.1  Fairchild shall make reasonable and diligent efforts to deliver
            assembled and/or tested Devices 


                                      -15-
<PAGE>

            on the delivery dates published to National. Any shipment made
            within +/- 3 days of the shipment date(s) published to National
            shall constitute timely shipment,

      10.2  All Devices delivered pursuant to the terms of this Agreement shall
            be suitably packed for shipment in National's specified 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. Fairchild shall not be responsible for
            delays in shipment resulting from National's failure to supply
            Fairchild with an adequate supply of National's specified
            containers. 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 6.1 above.

      10.3  National may, with Fairchild's prior written consent, reschedule
            delivery of any order of assembled and/or tested Devices once each
            fiscal period.

      10.4  Subject to the provisions of Section 7 hereof, National may cancel
            any purchase order at least two (2) weeks prior to the commencement
            of work by Fairchild without charge, provided that National
            reimburses Fairchild for the cost of any unique raw materials
            purchased after such purchase order has been placed, and provided
            further that Fairchild had provided National with a listing of
            materials it considers unique.

      10.5  As of 12:01 A.M. on the Effective Date, National will consign to
            Fairchild all Devices located at the Facilities upon which National
            had previously commenced services but which have not yet been
            completed, which Devices are termed work in process in the Purchase
            Agreement and which are not purchased by Fairchild thereunder.
            Unless expressly directed in writing by National otherwise,
            Fairchild shall commence performing 


                                      -16-
<PAGE>

            services hereunder to bring such Devices to a normal state of
            completion. National shall pay Fairchild for the accumulated
            additional processing costs, plus a twenty-five percent (25%) mark
            up, for the additional servicing taking place after the Effective
            Date. The provisions of Sections 6 and 11 hereof shall specifically
            apply to all such Devices.

11.0  QUALITY AND YIELD PROGRAMS

      11.1  Fairchild shall maintain continuous cost, quality and yield
            enhancement programs throughout the term of this Agreement.

      11.2  Fairchild shall support National quality programs and shall supply
            to National reports and/or manufacturing data in standard Fairchild
            format that are in effect and which are required as of the Effective
            Date.

      11.3  Fairchild hereby warrants that the Facilities currently are, and
            will remain throughout the term of this Agreement, ISO9000
            certified.

12.0  ON-SITE INSPECTION AND INFORMATION

      12.1  Fairchild shall allow National and/or National's customers to visit
            and evaluate the Facilities 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 these visits will not occur more than once per
            quarter on average.

      12.2  Upon National's written request, Fairchild will provide National
            with process control information, to include but not be limited to:
            SPC, yield and other detailed assembly and test quality and
            reliability data and associated analyses required to support
            National and National's customers quality and reliability 


                                      -17-
<PAGE>

            programs. Except for exigent circumstances, such requests shall not
            be made more than twice per year for a given category of
            information.

      12.3  Upon National's request and Fairchild's agreement, which shall not
            be unreasonably withheld, Fairchild shall provide National engineers
            with access to the Facilities to the extent necessary to perform
            yield improvement and product management updates relevant to this
            Agreement. National's engineers will comply with all applicable
            Fairchild regulations in force at the Facilities and National hereby
            agrees to hold Fairchild harmless for any damages or liability
            caused by any such National engineer which are attributable to: (i)
            the negligence or willful malfeasance of such engineer and (ii) any
            failure to comply with Fairchild's regulations in force at the
            Facilities or with applicable law.

13.0  REPORTS AND COMMUNICATIONS

      13.1  Each Party hereby appoints a Program Manager whose responsibilities
            shall include acting as a focal point for the technical and
            commercial discussions between them related to the subject matter of
            this Agreement, to include monitoring within his or her respective
            company the distribution of Confidential Information received from
            the other Party and assisting in the prevention of the unauthorized
            disclosure of Confidential Information within the company and to
            third parties. The Program Managers shall also be responsible for
            maintaining pertinent records arranging such conferences, visits,
            reports and other conditions as are necessary to fulfill the terms
            and conditions of this Agreement. The names, addresses and telephone
            numbers of the Program Managers will be communicated between the
            Parties from time to time.

14.0  EXPORT CONTROL

      14.1  The Parties acknowledge that each must comply with all rules and
            laws of the United States government relating to restrictions on
            export. 


                                      -18-
<PAGE>

            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.

      14.2  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,
            Die, Devices, technology or technical information received
            hereunder, that would be in contravention of any laws and
            regulations published by any United States government agency.

15.0  TERM AND TERMINATION

      15.1  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 (8) fiscal periods prior to the end of such
            thirty-ninth (39th) fiscal period determine in good faith a
            ramp-down schedule of production under this Agreement so as to
            minimize disruption to both Parties at the termination of this
            Agreement. 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
            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 any such reduction.

      15.2  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 in-

<PAGE>

                  voluntary 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.

      15.3  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 and/or complete any production ramp-down
            activity. Nothing in this Section 15 is intended to relieve either
            Party of any liability for any payment or other obligation existing
            at the time of termination.

      15.4  The provisions of Section 2, 14, 16 and Paragraphs 6.2, 6.3, 17.5
            and 17.8 shall survive the termination of this Agreement for any
            reason.

16.0  CONFIDENTIALITY

      16.1  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 


                                      -20-
<PAGE>

            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.

      16.2  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, 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.

      16.3  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.


                                      -21-
<PAGE>

      16.4  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 expense 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.

17.0  GENERAL

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

      17.2  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.

      17.3  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 


                                      -22-
<PAGE>

            contemplated by the Purchase Agreement or any bona fide financial
            institution engaged in 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.

      17.4  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.

      17.5  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.

      17.6  WAIVER: Should either of the Parties fail to exercise or enforce any
            provision of this Agreement such failure 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.

      17.7  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.

      17.8  LIMITATION OF LIABILITY: IN NO EVENT SHALL EITHER PARTY BE LIABLE
            FOR ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
            RESULTING 


                                      -23-

            AGREEMENT, OR THE FURNISHING, PERFORMANCE, OR USE OF ANY GOODS OR
            SERVICES SOLD PURSUANT HERETO, WHETHER DUE TO BREACH OF CONTRACT,
            BREACH OR WARRANTY, NEGLIGENCE OR OTHERWISE, REGARDLESS OF WHETHER
            THE NONPERFORMING PARTY WAS ADVISED OF THE POSSIBILITY OF SUCH
            DAMAGES OR NOT.

      17.9  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 this

      17.10 INTEGRATION: The agreement of the Parties, which is composed of this
            Agreement and the Exhibits hereto and the documents referred to
            herein, constitutes the entire agreement and understanding 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.

      17.11 PUBLIC ANNOUNCEMENT: Prior to the closing of the transactions
            contemplated under the Purchase Agreement, neither Fairchild nor

            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, securities laws 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 


                                      -24-

            under the Securities Act of 1933 in connection with obtaining such
            financing.

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

      17.13 BINDING EFFECT: This Agreement and the rights and obligations

      over[CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
      SECURITIES AND EXCHANGE COMMISSION], effective the date of closing of the
      purchase agreement.

o     Price will be fixed for the first [CONFIDENTIAL INFORMATION OMITTED AND

o     Cost base for FM Class 1 will be Q4 Forecast FY97 with a fully capitalized
      base.

objective. Such obligation, however, does not require 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.

            1.3 "Confidential Information" shall have the meaning set forth in
Paragraph 16.1 below.

            1.4  "Effective Date" shall mean the date first set forth above.

2.0  PROCESSES

            2.1 All manufacturing hereunder shall take place at the Facility.
National shall not manufacture Wafers or transfer any Fairchild-owned
intellectual property or technical information outside of the Facility other
than as may be permitted under this Agreement.

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


          -3-
<PAGE>

cesses become obsolete.

            2.3 National agrees to utilize Best Efforts to allow Fairchild to
source Wafers from Taiwan Semiconductor Manufacturing Corporation ("TSMC") by
means of the Joint Purchasing Arrangements as provided in the Transition
Services Agreement between the Parties of even date herewith. Fairchild's target
eight-inch Wafer process flow and expected eight-inch Wafer requirements are set
forth in Exhibit H hereto.

            2.4 After qualification is successfully completed for any Product to
be manufactured under this Agreement, if National desires to make material
Process changes affecting form, fit or function, National will notify Fairchild
of the intended change in accordance with National's process change procedures
then in effect. If the proposed changes are unacceptable to Fairchild, Fairchild
and National shall work together in efforts to resolve the problem and qualify
the changed Process for making Wafers. If during the first fifteen (15) fiscal
periods of this Agreement the Parties are unable to resolve the problem,
National shall continue to run the unmodified Process to supply Wafers pursuant
to this Agreement. After the first fifteen (15) fiscal periods of this
Agreement, if the Parties are unable to resolve the problem, National shall have
the right to make such Process changes upon the provision of ninety (90) days
prior written notice to Fairchild.

            2.5 Should National elect to discontinue a Process, it must give
Fairchild written notice of no less than twelve (12) fiscal periods. In no
event, however, may National discontinue any Process during the first
thirty-nine (39) fiscal periods of this Agreement unless Fairchild agrees.
Subsequent to National's notice of Process discontinuance, National will make
provisions with Fairchild for Last Time Buys, and commit to ship all Wafers
requested in such Last Time Buys as the Parties may negotiate.

            2.6 Just prior to the qualification of National's eight inch (8")
wafer fab in South Portland, Maine and National's 0.35 micron CMOS process
technology in that wafer fab, the Parties will undertake good faith negotiations
to make foundry capacity in said 8" wafer fab available to Fairchild under terms
generally similar to those hereunder.

3.0   EXISTING PRODUCTS; SET UP AND QUALIFICATION OF NEW
      PRODUCTS; MODIFICATION OF EXISTING PRODUCTS

            3.1 For each new Product that Fairchild proposes to have National
manufacture, Fairchild will provide to National in advance the Specifications
and design layout of the Product for 


          -4-
<PAGE>

review and comment by National. 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.

            3.2 An initial data base for Mask generation or pattern generation,
or acceptable production Masks will be provided by Fairchild to National, at
Fairchild's expense, for each new Product to be fabricated for Fairchild. In the
alternative, Fairchild may provide National with prime die design data and
National will provide the frame and fracture services and procure the Mask set
at Fairchild'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 National. All such data
bases, pattern generation tapes and Mask sets shall be the property of
Fairchild, regardless of whether they were initially supplied by Fairchild or
replaced by National.

            3.3 As soon as practical following agreement on the items in
Paragraph 3.1 above, and following receipt of a written purchase order from
Fairchild, National will begin manufacture of one or more lots of twelve (12)
prototype Wafers for such Product as is specified in the purchase order.
National will perform the electrical testing specified in the initial Acceptance
Criteria and supply the test data to Fairchild with the prototype Wafers.
National's obligation shall be limited to providing Wafers that meet the
applicable PCM specifications and the associated test data. Fairchild will
promptly inspect the prototype Wafers and notify National 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.

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

            3.5 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 3. In the event that Fairchild desires
for National to manufacture production quantities, the Parties will agree in
writing on the terms before National accepts the purchase order.


          -5-
<PAGE>

            3.6 If either Fairchild or National desires to make any changes to
the final Specifications, Acceptance Criteria or Quality and Reliability
Criteria for any existing 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.

            3.7 National may at its discretion declare a Product obsolete if
such Product has not been run in production for a minimum of six (6) fiscal
periods. National must provide Fairchild with twelve (12) months prior written
notice of an obsolescence declaration and make reasonable provisions with
Fairchild for a Last Time Buy for such Product. Within thirty (30) days after
completing production of Fairchild's Last Time Buy, National shall return all
data bases and Masks for such Product to Fairchild.

4.0  CAPACITY; VOLUME COMMITMENTS; PRODUCTION PLANNING

            4.1 All planning herein will be done under National's accounting
calendar which currently divides its fiscal year into four (4) equal fiscal
quarters, each of which consists of three (3) fiscal periods. The first two (2)
periods of each quarter are of four (4) weeks in duration and the third period
is of five (5) weeks duration.

            4.2 Two (2) weeks prior to the end of each National fiscal period
Fairchild will provide in writing to National a baseline quantity of Wafers, set
forth in terms of Wafer starts by Wafer Module, for the next eight (8) fiscal
periods (the "Capacity Request"). The Capacity Request shall clearly state each
Wafer in terms of six-inch (6") Equivalent Wafers. Equivalency factors are set
forth in Exhibit A. Fairchild's initial Capacity Request and National's Assured
Capacity response formats are set forth in Exhibit D.

            4.3 Each fiscal period Fairchild may change the Capacity Request in
accordance with the following table, provided that the maximum Capacity Request
does not exceed Fairchild's share of a Wafer Module's installed equipment
capacity as provided herein. Any changes outside those permitted under the
following table must be by mutual consent of the Parties.

                Period 8                                 +/-40%

            4.4 Fairchild's share of a Wafer Module's installed equipment
capacity will equal the previous National Assured Capacity for the Wafer Module,
plus that percentage of any excess capacity available in the Wafer Module equal
to Fairchild's percentage of the currently utilized capacity in said Wafer
Module. Installed equipment capacity is set forth below:

            Wafer Module                  Annual Capacity
            ------------                  ---------------
            Arlington, TX                 20,000 6" wafers

            4.5 One (1) work week after receipt of the Capacity Request,
National shall provide Fairchild with a response to such Capacity Request, the
"National Assured Capacity". The National Assured Capacity must guarantee the
amount requested in Fairchild's latest Capacity Request, provided that any
changes to Fairchild's latest Capacity Request are within the limits of
Paragraph 4.3. National shall utilize its Best Efforts to comply with any
requests by Fairchild for capacity above those which are permitted under
Paragraph 4.3. In any case, National shall be obligated hereunder to provide
Fairchild with the Wafer starts guaranteed in the National Assured Capacity
response. The initial National Assured Capacity response will be the last one
provided prior to the Effective Date. Set forth below are two examples of the
foregoing:

Example #1  The new Capacity Request is less than the last National Assured
            Capacity response.

            4.6 The timetable for the rolling eight fiscal period Capacity
Request, the National Assured Capacity response, purchase order release and
detailed device level Wafer starts request for the next fiscal period are set
forth in Exhibit D hereto.

5.0  PURCHASE ORDERS

            5.1 All purchases and sales between National and Fairchild shall be
initiated by Fairchild'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 in
the future. They shall state the Wafer quantities (specifying whether
equivalents or actual) by Wafer Module, and shipping and invoicing instructions.
National shall accept purchase orders through a written or electronic
acknowledgment. Within a reasonable time after receipt of Fairchild's detailed
device level Wafer starts request for the next fiscal period, National shall
provide Fairchild with a Wafer 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 4, as the embodiment of the purchase order for specifying
the Wafer quantity by Wafer Module and Process, and whether sorted or unsorted.

            5.2 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;


          -8-
<PAGE>

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

            5.3 Consistent with standard practices of issuing specific device
level details of part numbers to be fabricated on a weekly or periodic basis,
Fairchild may unilaterally change the part number to be manufactured, provided
that National agrees that the change does not negatively impact National'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 National's agreement; National 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 electronic data
exchange, or other mutually satisfactory system.

            5.4 Fairchild shall request delivery dates which are consistent with
National's reasonable lead times for each Product as indicated at the time
Fairchild's purchase order is placed. Notwithstanding the foregoing, National
shall utilize its Best Efforts to accommodate requests by Fairchild 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.

            5.5 National may manufacture lots of any size which satisfy the
requirements of effective manufacturing. However, Fairchild must place orders
for full flow and prototype Products in increments of twelve (12) or twenty-four
(24) Wafers.

6.0  PRICES AND PAYMENT

            6.1 Set forth herein in Exhibit M is the Forecasted Volume of Wafers
by Process that Fairchild will purchase from National during the term of this
Agreement. Set forth in Exhibit N hereto are the prices which Fairchild shall
pay to National for Wafers manufactured hereunder during the first six (6)
fiscal periods of this Agreement.

            6.2 The Parties hereby acknowledge that the prices Fairchild shall
pay to National for silicon wafers manufactured pursuant to this Agreement are
based on the collateral transactions and ongoing relationship between the
Parties as expressed in the Purchase Agreement, Revenue Side Letter and
corresponding Fairchild Foundry Services Agreement, Fairchild Assembly Services
Agreement, and Mil/Aero Wafer and

          -9-
<PAGE>

Services Agreement of even date herewith between the Parties (collectively the
"Operating Agreements"). The prices which Fairchild shall pay to National for
Wafers manufactured hereunder after the first six (6) fiscal periods of this
Agreement are set forth herein at Exhibit L. In addition, Products that qualify
will be subject to a die cost adjustment as provided in Exhibit E.

            6.3 For purposes of Exhibit L, Fairchild, or any "Big 6" accounting
firm designated by Fairchild, shall have reasonable rights to audit not more
than twice each fiscal year the books and records of National relevant to the
pricing terms of this Agreement in order to come to agreement with National with
regard to National's actual manufacturing costs.

            6.4 Prices are quoted and shall be paid in U.S. Dollars. Such prices
are on an FOB ship point basis. Payment terms are net thirty (30) from date of
invoice. Miscellaneous services may be invoiced separately.

            6.5 Fairchild shall pay, in addition to the prices quoted or
invoiced, the amount of any freight, insurance, special handling and duties.
Fairchild shall also pay all sales, use, excise or other similar tax applicable
to the sale of goods or provision of services covered by this Agreement, or
Fairchild shall supply National with an appropriate tax exemption certificate.

            6.6 Fairchild shall in no event be required to pay prices in excess
of those charged by National for other third party foundry customers, for
substantially similar products sold on substantially similar terms (e.g.,
volume, payment terms, manufacturing criteria, contractual commitments vs. spot
buys, etc.). In the event National desires to perform such foundry services for
other third party customers at such lower prices, National shall immediately
notify Fairchild and Fairchild shall begin receiving the benefit of such lower
price at the same time as such other third party customer. This Paragraph 6.6
shall not apply to the prices to be paid by Fairchild hereunder for the first
twelve (12) fiscal periods of this Agreement, or for "spot buys" intended to
fill underutilized capacity thereby caused by Fairchild.

7.0   OTHER MANUFACTURING SERVICES

            7.1 At Fairchild's request, National will perform Wafer sort and
test services based on sort and test programs prepared, owned and otherwise
proprietary to Fairchild. Towards that end, Fairchild shall supply National with

performed as of the Effective Date. Any additional requests are subject to fees
set forth in Exhibit J.

8.0  DELIVERY; RESCHEDULING AND CANCELLATION

            8.1 National shall make reasonable and diligent efforts to deliver
Wafers on the delivery dates specified in the Product delivery schedule provided
by National pursuant to Paragraph 5.1. 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 or minus five percent (5%) of the quantity
ordered.

            8.2 If National has not made shipment of Products within fifteen
(15) days after the shipment date specified in the Product delivery schedule
provided by National pursuant to Paragraph 5.1, Fairchild shall have the right,
subject to Paragraph 18.2, to cancel that portion of its purchase order
pertaining to such Products, but only in the event that Fairchild's customer for
those Products has cancelled its order with Fairchild for such Products.
Notwithstanding the foregoing, if National has not made shipment of Products
within thirty (30) days after the shipment date specified in the Product
delivery schedule, Fairchild shall have the right, subject to Paragraph 18.2, in
its sole discretion, to cancel that portion of its purchase order pertaining to
such Products, regardless of whether Fairchild's customer has cancelled its
order with Fairchild or not.

            8.3 All Wafers delivered pursuant to the terms of this Agreement
shall be suitably packed for shipment in National's standard containers, marked
for shipment to Fairchild's address set forth in the applicable purchase order
and delivered to a carrier or forwarding agent chosen by Fairchild. Should
Fairchild fail to designate a carrier, forwarding agent or type of conveyance,
National 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 Fairchild. Shipments will be subject to incoming
inspection as set forth in Paragraph 9.2 below.

            8.4 To facilitate the inspection of Product deliveries to Fairchild,
lot integrity shall be maintained on all such deliveries, unless specifically
waived by mutual agreement of the Parties.


          -12-
<PAGE>

            8.5 Subject to the provisions of Section 5 hereof, Fairchild may
cancel any purchase order upon at least one (1) week's notice prior to the
commencement of manufacturing without charge, provided that Fairchild reimburses
National for the cost of any unique raw materials purchased for such order.

            8.6 Fairchild may request that National stop production of Wafers in
process for Fairchild's convenience and National will consider stopping
depending on the point of process. In such event, Fairchild 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 National is able to
utilize the unfilled capacity. National will, if reasonably practicable, restart
production of stopped Wafers one time within a reasonable time after receipt of
a written request from Fairchild, subject to Fairchild's payment of any
additional expenses incurred. Sections 9, 10 and 11 of this Agreement shall not
apply to Wafers stopped under this Paragraph 8.6 for more than thirty (30) days,
nor shall National make any commitments of yield with respect to such Wafers.

            8.7 In the event that Fairchild elects to maintain an inventory of
partially finished Wafers, ownership of the partially finished Wafers will pass
to Fairchild when they reach the holding point defined by the relevant Process
flow. National will invoice Fairchild for such Wafers, but they will be stored
under clean-room conditions and remain in the Wafer processing WIP management
system. National will inform Fairchild 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 Fairchild at
any time. National shall credit Fairchild with the amount previously invoiced
for any such Wafers at such time as they are restarted in the Process flow.

            8.8 As of 12:01 A.M. on the Effective Date, Fairchild will own all
Wafers located at the Facility which National has commenced processing but which
have not yet been completed in accordance with the pertinent Process flow.
Unless expressly directed by Fairchild otherwise, National shall continue to
process each Wafer to a normal state of completion in the applicable Wafer
Module. Fairchild shall pay National 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 9, 10
and 11 hereof, shall specifically apply to all such Wafers.

9.0  QUALITY CONTROL AND INSPECTION; AND RELIABILITY

            9.1 National will manufacture Wafers in accordance with the Quality
and Reliability Criteria for the applicable Product. Prior to shipment, National
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. National will only ship those Wafer lots that successfully pass
the applicable Acceptance Criteria. National will electronically provide
Fairchild 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.

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

            9.3 Fairchild shall promptly provide for yield probe tests to be
conducted on the Wafers and communicate the results of the tests to National
within thirty (30) days of receipt of Wafers from National. The right to return
any Wafers for low yield shall be governed by Section 10 below.

            9.4 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 National
hereunder. To the extent that those policies are not inconsistent with the
provisions of this Agreement, Fairchild shall not be required to accept delivery
of any Wafers hereunder if National fails to comply with said policies or such
other similar policies

          -14-
<PAGE>

as may be mutually agreed to in writing by the Parties.

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

10.0  MINIMUM YIELD ASSURANCES

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

            10.2 The baseline yield and initial MYA for each Product to be
manufactured by National hereunder is set forth in Exhibit B hereto.

            10.3 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 Fairchild makes any modifications to said test programs.

            10.4 For Products that qualify for die cost sharing, as provided in
Exhibit E, the baseline Net Die Per Wafer (NDPW) for the Product will be used
for defining the MYA. For all other Products, 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 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%.

            10.5 MYA will be determined as follows. For purposes of Wafers
manufactured in the Facility, Wafers which yield less than sixty percent (60%)
of the mean will be considered discrepant and may be returned for full credit at
Fairchild's discretion. In no event shall National accept returns of Wafers on
non-released products.


          -15-
<PAGE>

            10.6 Fairchild shall provide yield analysis information on Wafers
returned to National under this Section 10, in order to assist National in
continuous Process improvement.

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

11.0  WARRANTY

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

            (i)   National is notified in writing promptly upon discovery
                        with a detailed description of any such defect in any
                        Product (at which time National shall issue a return
                        material authorization number to Fairchild), and;

           (ii)   Fairchild returns such Product to the applicable
                        Facility at Fairchild's expense for inspection;
                        and

          (iii)   National's examination of such Product reveals that the
                        Product is indeed defective and does not meet the
                        applicable Quality and Reliability Criteria or is
                        defective in materials or National'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 National

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

            11.2 THE FOREGOING WARRANTY CONSTITUTES NATIONAL'S


          -16-
<PAGE>

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

12.0  ON-SITE INSPECTION AND INFORMATION

            12.1 National shall allow Fairchild and/or Fairchild'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
Fairchild and National that Fairchild must obtain the concurrence of National
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.

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

circumstances, such requests shall not be made more than twice per year for a
given category of information.

13.0  PRODUCT ENGINEERING SUPPORT

            13.1 The Parties will cooperate in allowing Fairchild employees to
have reasonable access to the Facility during the term of this Agreement (the
"Fairchild Engineering Team"), in order to assist in Product developments and
improvements. National will provide reasonable office space to the Fairchild
Engineering Team, if required on a temporary basis, not to exceed sixty (60)
days per occurrence, at no expense to Fairchild. Should the Fairchild
Engineering Team require long term, dedicated office space, Fairchild agrees to
pay National the overhead cost associated with such space. The Fairchild
Engineering Team will comply with all applicable National regulations in force

<PAGE>

willful malfeasance of such member, and (ii) any failure by such member to
comply with National's regulations in force at the Facility or with applicable
law.

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

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

14.0  TERM AND TERMINATION

            14.1 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 (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, Fairchild 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. Fairchild will provide National with not less than
ninety (90) days prior written notice of any such reduction.

            14.2 This Agreement may be terminated, in whole or in part, by one
Party sending a written notice to the other Party of its election to terminate,
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, 


          -18-
<PAGE>

                  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.

            14.3 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 National may continue to retain and use any rights or property
belonging to Fairchild solely for the period necessary for it to finish
manufacturing during any ramp-down period. Nothing in this Section 14 is
intended to relieve either Party of any liability for any payment or other
obligations existing at the time of termination.

            14.4 The provisions of Sections 11, 15, 16 and Paragraphs 18.5 and
18.8 shall survive the termination of this Agreement for any reason.

                             DIE COST IMPACT SHARING

1.0  GENERAL

1.1 Fairchild and National will implement 50:50 sharing of yield gain and loss
implemented in accordance with the principles set forth in this Exhibit.

1.2 The yield adjustment amount will be calculated at the end of the first six
(6) fiscal periods ("Fiscal Half") from the Effective Date and each Fiscal Half
thereafter, retroactively. Fairchild will pay National a yield premium fee in
the case of average yield improvement; National will reimburse Fairchild in the
case of average yield degradation 

1.3 Net Die Per Wafer (NDPW) will be used as the basis for the calculation.

2.0 ESTABLISHING YIELD BASELINE

2.1 In order to qualify for die cast sharing, Products must (i) have achieved a
minimum production volume of at least ninety-six (96) Wafers (i.e., the
equivalent of at least four 24-Wafer or eight 12-Wafer lots) per period for
three (3) of the preceding six (6) fiscal periods (a minimum of 288 Wafers) and
(ii) have a stable yield history (e.g., without known yield or test
sensitivities. The baseline NDPW of each qualifying Product as of the Effective
Date shall be the average NDPW of the preceding six (6) fiscal periods. Baseline
NDPWs will reset twelve (12) fiscal periods ("Fiscal Year") after the Effective
Date and at the end of each Fiscal Year thereafter. 

2.2 A baseline NDPW will be established for a new Product after the Product has
achieved a minimum production volume of at least 96 Wafers per fiscal period
(i.e., the equivalent of at least four 24-Wafer of eight 12-Wafer lots) for
three (3) of the preceding six (6) fiscal periods (a minimum of 288 Wafers) and
(ii) has established a stable yield history (e.g., without known yield or test
sensitivities). Once a baseline NDPW has been established for a Product and
mutually agreed upon by the Parties, such baseline NDPW will remain in effect
until the next Fiscal Year reset point.

2.3 In case of a change in the sort program which affects the yield, a
new baseline NDPW will be mutually agreed upon based on the effect of the change
on the Product yield. The new baseline will apply to all lots measured after the
change has been implemented. 

2.4 In the case of a Mask change which affects the yield, a new baseline NDPW
will be established as provided in Paragraph 2.2 of this Exhibit.

2.5 For Products that are not sorted by National the Parties will agree on
procedures to assure that production sort programs cannot be changed without
National's acknowledgment, and the provisions of Paragraph 2.3 of this Exhibit
shall apply to any such changes.

2.6 In order for a Product that is not sorted by National to qualify for die
cast sharing, Fairchild must make wafer sort and yield data, and wafers (at
National's cost) as required for analysis, available to National on a timely
basis and in conformance with National's own internal requirements for such
data.

3.0 CALCULATIONS

<PAGE>

3.1 At the end of each Fiscal Half, a Product list to be used for the yield
adjustment calculation will be mutually agreed by the Parties. Each Product in
this list shall (i) have an established baseline NDPW; ( ii ) have achieved a
minimum production volume of at least ninety-six (96) Wafers per period (i.e.
the equivalent of four 24-Wafer or 8 12-Wafer lots) for three (3) of the
preceding six (6) fiscal periods (a minimum of 288 Wafers); and (iii) have
established a stable yield history (e.g., without known yield or test
sensitivities). 

3.2 The percent change in NDPW for the preceding Fiscal Half will be calculated
for each qualifying Product based on the difference between the baseline and
actual NDPW for the Product; 

3.3 The semiannual adjustment for die cast sharing will equal:
           (Base Wafer Price) X (NDPW Percent Change) X (0.5) X (Wafers Shipped)

3.4 The total adjustment will be the sum of the adjustments of the qualifying
Products.

3.5 National will perform the die cast sharing calculation and provide an
accounting to Fairchild following the end of each Fiscal Half together with an
invoice of a credit for the die cost adjustment amount.

4.0 OTHER

4.1 MYA will be used in conjunction with die cost sharing for purposes of
identifying "Maverick" wafers that will be discarded (unless Fairchild agrees to
accept). For Products that qualify for die cost sharing, the baseline NDPW will
be used as the basis for defining the MYA for the Product.

4.2 Wafer price adjustments to reflect changes in National's manufacturing cost
base are independent of die cost sharing.

                            WAFER ACCEPTANCE CRITERIA

National Electrical Test Acceptance Method:

Acceptance of National Wafers for shipment to Fairchild shall be determined per
mutually agreed upon electrical parameter test distribution performance with
standard test die. National's wafer acceptance methodology is detailed in
Arlington specification SP-0008. The method depends on two classes of Kiethley
files:

      Limit files                               Identified as *.lim
      Dispo (sition) files                      Identified as *.dsp

The former contain the electrical test limits, and the latter define the
accept/reject criteria per wafer, and in some cases per lot, by individual test.
The *.lim and *.dip files are identified in Exhibit A.

Arlington, Texas Wafer Acceptance and Wafer Sort:

1.    Each lot will be sampled at PCM test prior to Wafer sort. Five wafers per
      lot will be sampled and subjected to electrical test.

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

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

National Wafer Fabrication and Fairchild Wafer Sort:

1.    A ten (10) Wafer lot sample will be tested to the applicable PCM
      specification prior to shipment to NSC. Keithly *.dsp and *.lim files will
      govern the acceptances and rejections. 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 PCB will be shipped to National.

2.    Individual PCM SPECIFICATIONS (BY Process) are defined by the files called
      out in Exhibit A.

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

1.    Shortly prior to the conclusion of the first six (6) fiscal periods of
      this Agreement ("Fiscal Half"), the Parties shall meet in order to
      determine new prices for the second Fiscal Half. At the meeting the
      Parties will review the manufacturing history during such part of the
      first Fiscal Half, for which such information shall be available, in order
      to determine the Facility's actual manufacturing cost base, which shall be
      consistent with National's standard cost accounting practices in effect as
      of the Effective Date (the "Reference Cost Base"). If the Reference Cost
      Base, plus a [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
      THE SECURITIES AND EXCHANGE COMMISSION] is less than the price applicable
      for the first Fiscal Half, prices for the second Fiscal Half will be equal
      to its Reference Cost Base, plus a [CONFIDENTIAL INFORMATION OMITTED AND
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION]. Otherwise,
      the prices will remain the same as during the first Fiscal Half.

      The Reference Cost Base and second Fiscal Half prices will remain in
effect for the remaining term of this Agreement. Shortly prior to the conclusion
of the [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION] period of this Agreement, and every
[CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION] fiscal periods thereafter, the Parties shall meet in order
to determine National's actual manufacturing costs, which shall be consistent
with National's standard cost accounting practices in effect as of the Effective
Date, for the preceding Fiscal Half. If National's actual costs during the
previous Fiscal Half were lower than its Reference Cost Base, the Parties shall
calculate what Fairchild would have paid if such actual costs had been used in
originally setting the prices, rather than the Reference Cost Base. National
shall give Fairchild a credit equal to [CONFIDENTIAL INFORMATION OMITTED AND
FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] of the savings
Fairchild would have relaxed of it had paid the recalculated prices. No monies
will be owing to or from Fairchild or to or from National if National's actual
costs during the preceding Fiscal Half were higher than the Reference Cost Base.

2.    The prices for Wafers purchased during a National fiscal year in excess of
      the Forecast Volumes will be negotiated by the Parties on a case by case
      basis.

3.    Pricing for any extension and/or ramp-down period beyond the first
      thirty-nine (39) fiscal periods of this Agreement will be negotiated in
      good faith by the Parties.

CONFIDENTIAL PORTIONS OF THIS DOCUMENT HAVE BEEN DELETED AND FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT

      THIS NATIONAL ASSEMBLY SERVICES AGREEMENT ("Agreement") is dated and made
effective this 11th day of March, 1997 (the "Effective Date") by and between
NATIONAL SEMICONDUCTOR CORPORATION, a Delaware corporation, having its principal
place of business at 2900 Semiconductor Drive, Santa Clara, California
95052-8090 ("National") and FAIRCHILD SEMICONDUCTOR CORPORATION, a Delaware
corporation, having its principal place of business at 333 Western Avenue, South
Portland, Maine 04106 ("Fairchild"). National and/or Fairchild may be referred
to herein as a "Party" or the "Parties" as the case may require.

                              W I T N E S S E T H:

      WHEREAS, the Parties have entered into a certain Asset Purchase Agreement
(hereinafter referred to as the "Purchase Agreement") under which Fairchild is
acquiring certain of the assets of National's Logic, Memory and Discrete Power
and Signal Technologies Business Units as historically conducted and accounted
for (including Flash Memory, but excluding Public Networks, Programmable
Products and Mil/Aero Logic Products) (the "Business"); and

      WHEREAS, National owns and/or leases and operates assembly facilities in
Malacca, Malaysia and Singapore (the "Facilities"); and

      WHEREAS, Fairchild has been having assembly, test and other back-end
services performed at the Facilities by National; and

      WHEREAS, National and Fairchild desire to enter into an agreement under
which National will continue to provide certain services to Fairchild following
the closing of the transactions contemplated by the Purchase Agreement; and

      WHEREAS, National and Fairchild recognize that the prices for assembly and
test services to be provided by National to Fairchild as set forth herein are
determined based on the collateral transactions and ongoing relationship between
the Parties as expressed in the Purchase Agreement, Revenue Side Letter between
National and Fairchild of even date herewith (the "Revenue Side Letter") and the
other Operating Agreements (as defined in Paragraph 8.2); and

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

      NOW, THEREFORE, in furtherance of the foregoing premises and in
consideration of the mutual covenants and obligations 
<PAGE>

hereinafter set forth, the Parties hereto, intending to be legally bound hereby,
do agree as follows:

1.0   DEFINITIONS

      1.1   "Best Efforts" shall require that the obligated Party make a
            diligent, reasonable and good faith effort to accomplish the
            applicable objective. Such obligation, however, does not require 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.

      1.2   "Confidential Information" shall have the meaning set forth in
            Paragraph 15.1 below.

      1.3   "Devices" shall mean Fairchild integrated circuits to be assembled
            and/or tested by National hereunder.

      1.4   "Die" shall mean the silicon die material, consigned by Fairchild to
            National in wafer form, from which Devices are assembled.

      1.5   "Effective Date" shall mean the date first set forth above.

      1.6   "Facilities" shall mean the existing assembly facilities located at
            Malacca, Malaysia and Singapore owned and/or leased and operated by
            National.

      1.7   "Fairchild" shall mean Fairchild Semiconductor Corporation and its
            Subsidiaries.

      1.8   "Mix" shall mean the allocation within a forecast by package type
            and pin count.

      1.9   "National" shall mean National Semiconductor Corporation and its
            Subsidiaries.

      1.10  "National Assured Capacity" shall mean the capacity of assembly
            and/or test services that National agrees to supply Fairchild
            pursuant to Section 6 below.


                                      -2-
<PAGE>

      1.11  "Specifications" shall mean Fairchild drawings, criteria and other
            documented specifications in effect as of the Effective Date,

            or similar entity more than fifty percent (50%) owned or controlled
            by a Party hereto, provided that any such entity shall no longer be
            deemed a Subsidiary after such ownership or control ceases to exist.

2.0   SHIPPING AND BUILD ORDER REQUIREMENTS

      2.1   National shall provide assembly and test services hereunder in
            accordance with the Specifications. Such services shall be performed
            at those Facilities at which they have historically been performed.

      2.2   Fairchild will, at "No Charge", deliver and consign to National at
            the Facilities its electrically probed wafers or wafers requiring
            wafer probe. If supplied in wafer form, any reject die on said
            wafers shall be ink marked or identified by Fairchild in a manner
            acceptable for use with National's pattern recognition equipment.
            Wafers and other materials shall be packed in accordance with the
            Specifications.

      2.3   National shall be responsible for forecasting and ordering lead
            frames, bonding wire, molding compound and other raw materials
            required for assembly in sufficient quantities and with sufficient
            lead times to meet its obligations under the National Assured
            Capacity. National shall also be responsible for maintenance and
            replacement costs associated with manufacturing tools and equipment
            (e.g., mold die, trim and form die, lead frame tooling), except for
            lead frame tooling which is owned by and used exclusively for
            Fairchild.

      2.4   Fairchild shall supply an appropriate bonding diagram and test
            program (if applicable) for each Device to be 


                                      -3-
<PAGE>

            assembled per the Specifications.

      2.5   National hereby agrees to verify the Die count and advise Fairchild
            of any variance greater than one percent (1%).

      2.6   Fairchild will provide National with a "Lot Traveler" in a format
            identical to that in effect on the Effective Date and outlined in
            Exhibit A hereto for the first six (6) months after the Effective
            Date. After that period of time, National may utilize its own
            Traveler, provided its form has previously been approved in writing
            by Fairchild, which approval shall not be unreasonably withheld.

      2.7   National shall provide Fairchild with the following manufacturing
            data, in a format and pursuant to criteria and procedures agreed to
            by the Parties, on a monthly basis:

            (a)   WIP from sealing through final assembly, including finished
                  goods;

            (b)   Test yield and wafer sort yield results (if applicable);

            (c)   Shipping activity (description, quantity, ship date);

            (d)   Acknowledgment of Fairchild Die shipments as well as such
                  other information which Fairchild may reasonably request from
                  time to time; and

            (e)   Cycle time (if requested by Fairchild).

      2.8   National shall deliver completed lots to Fairchild, packaged in
            accordance with the Specifications, with the assembly run card
            enclosed for each assembly lot (kit). Future traceability for a lot
            (kit) shall be based solely on the run card and shall be the
            responsibility of Fairchild. The assembly run card shall show the
            yield for each yield point in the assembly process. By mutual
            agreement of the Parties, traceability may instead be software
            based, so long as such records are accessible to both Parties.

      2.9   All assembly and test services shall take place at the Facilities.
            National shall not perform assembly or test services or transfer any
            Fairchild- owned intellectual property or other Fairchild technical


                                      -4-

            information outside of the Facilities or to any other site, unless
            mutually agreed upon by both Parties.

3.0   PACKAGE/PROCESS CHANGES NOTIFICATION

      3.1   If National proposes to make any change affecting the assembly
            processes, materials and/or suppliers, to include, but not be
            limited to, lead frame design, lead frame material, die attach
            material, wire bond material, molding compound, lead plating process
            or plating material, test programs or assembly procedures affecting
            the Devices, National will notify Fairchild of the intended change
            in accordance with National's change procedures then in effect. If
            the proposed change is unacceptable to Fairchild, Fairchild and
            National shall work together in efforts to resolve the problem. If
            during the first thirty-nine (39) fiscal periods of this Agreement
            the Parties are unable to resolve the problem, National shall not
            make the proposed change. After the first 39 fiscal periods of this
            Agreement, if the Parties are unable to resolve the problem,
            National shall have the right to make such change upon the provision
            of ninety (90) days prior written notice to Fairchild.
            Notwithstanding the foregoing, however, National shall in no event
            manufacture Devices other than in strict accordance with the
            Specifications, or any amendments thereto, without the prior written
            consent of Fairchild.

      3.2   Fairchild shall provide at least fifteen (15) days prior written
            notice to National of any proposed change in Die design, layout
            modification, fabrication process, test programs or other changes
            which may impact upon National's processing, handling or assembly of
            Devices. National shall not be responsible for any assembly or test
            loss incurred as a result of Fairchild's failure to provide timely
            notification of such change.

      3.3   Fairchild reserves the right to make changes to the Specifications
            that reflect improvements, developments or other technically desired
            changes in the Devices. Fairchild shall notify National of such
            requested change orders and National shall respond within thirty
            (30) working days regarding the feasibility, schedule and
            anticipated costs of implementing such change orders. Once the
            parties have agreed in writing to the engineering changes, schedule
            and prices thereof, National shall promptly take all measures
            required to 


                                      -5-
<PAGE>

            incorporate such change orders into the Devices. National shall have
            the right to renegotiate the price and/or its capacity commitments
            hereunder if such changes will have an adverse effect on National's
            assembly or test capacity.

4.0   DEVICE ACCEPTANCE/QUALIFICATION/RAMP UP

      4.1   Should National agree to add new package types requested by
            Fairchild, National shall utilize its Best Efforts to complete
            qualification assembly of new package types as soon as possible,
            including qualification lots. Fairchild shall reimburse National for
            the full costs of equipment, tooling and one time start up costs
            required to manufacture new packages that National will use
            exclusively for Fairchild, otherwise such costs will be shared.

      4.2   Fairchild shall be responsible for specifying and performing any
            qualification testing deemed necessary.

      4.3   National reserves the right to refuse assembly of any new Devices
            which violate National internal design or processing requirements
            that are introduced after the Effective Date.

      4.4   National shall provide Fairchild with a preliminary ramp up
            schedule, which may be subject to subsequent reduction by National
            in the event unforeseen problems are encountered by National with
            yields, process, capacity support, quality/reliability or other
            product or process features. National shall immediately notify
            Fairchild in writing of the necessity of any such reductions.

5.0   INSPECTION, ACCEPTANCE AND WARRANTY

      5.1   For those Devices not tested by National, Fairchild shall conduct
            incoming acceptance tests within ten (10) days after delivery at its
            test facility. Upon completion of such tests, Fairchild shall
            promptly report any shortage, damage or defective Devices in any
            shipment. In the case of defective Devices found by Fairchild to
            exceed applicable AQL and/or PPM Limits in effect as of the
            Effective Date, or as subsequently agreed to in writing by the
            Parties, Fairchild shall promptly ship samples of defective Devices
            to National for verification. If such testing 


                                      -6-
<PAGE>

            demonstrates that the shipment failed to meet the relevant
            Specifications due to National workmanship and materials, Fairchild
            may at its option either:

            (a)   deduct the defective Devices' purchase price from National's
                  invoice, in which event Fairchild shall, if requested by
                  National, return to National the damaged or defective Devices
                  at National's risk and expense; or

            (b)   return the damaged or defective Devices to National, at
                  National's risk and expense, for credit; or

            (c)   scrap the defective Devices at National's request for credit.

      5.2   National warrants that the services provided to Fairchild hereunder
            shall conform to all applicable Specifications for assembly and/or
            test and shall be free from defects in material and National's
            workmanship. Such warranty, however, shall not apply to the design
            or operation of the Fairchild supplied Die incorporated in the
            Devices. This warranty is limited to a period of one (1) year from
            the date of delivery to Fairchild. If, during the one year period:

           (i)  National is notified promptly in writing upon discovery of any
                   such defect in any Device with a detailed description; and

          (ii)  Fairchild receives a return material authorization number from
                   National and returns such Device to the applicable Facility 
                   at Fairchild's expense for inspection; and

         (iii)  National's examination reveals that the Device is indeed
                   defective and does not meet the applicable Specification or
                   is defective in materials or National'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 National

            then, within a reasonable time, National shall credit Fairchild for
            such defective Device. National shall reimburse Fairchild for the
            transportation charges paid by Fairchild in returning such defective
            Devices 


                                      -7-
<PAGE>

            to National. The performance of this warranty shall not act to
            extend the one (1) year warranty period for any Device(s) repaired
            or replaced beyond that period applicable to such Device(s) as
            originally delivered.

      5.3   THE FOREGOING WARRANTY CONSTITUTES NATIONAL'S EXCLUSIVE LIABILITY,
            AND FAIRCHILD'S EXCLUSIVE REMEDY, FOR ANY BREACH OF WARRANTY.
            NATIONAL MAKES AND FAIRCHILD RECEIVES NO WARRANTIES OR CONDITIONS ON
            THE SERVICES PERFORMED HEREUNDER, EXPRESS, IMPLIED, STATUTORY OR
            OTHERWISE, AND NATIONAL SPECIFICALLY DISCLAIMS ANY WARRANTY OF
            MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

6.0   CAPACITY; VOLUME COMMITMENTS; PRODUCTION PLANNING

      6.1   All planning herein will be done under National's accounting
            calendar which currently divides its fiscal year into four (4) equal
            fiscal quarters, each of which consists of three (3) fiscal periods.
            The first two (2) periods of each quarter are of four (4) weeks in
            duration and the third period is of (5) weeks duration.

      6.2   Two (2) weeks prior to the end of each National fiscal period, or as
            otherwise agreed by the Parties, Fairchild will provide to National
            a baseline quantity of assembly starts set forth in terms of product
            family, package and pin count, for the next eight (8) fiscal periods
            (the "Capacity Request"). Fairchild's initial Capacity Request and
            National's Assured Capacity response formats are set forth herein at
            Exhibit B.

      6.3   Each fiscal period, Fairchild may make changes to the Capacity
            Request in accordance with the following table, provided that the
            maximum Capacity Request for each package and pin count module does
            not exceed Fairchild's share of each package and pin count module's
            installed equipment capacity. Any changes outside those permitted
            under the following table must be by mutual consent of the Parties.

               Fiscal Periods in the
                  Capacity Request              Permitted Changes
               ---------------------            -----------------
                      Period 1                        Fixed
                      Period 2                        +/-10%
                      Period 3                        +/-20%
                      Period 4                        +/-40%


                                      -8-
<PAGE>

                      Period 5                        +/-40%
                      Period 6                        +/-40%
                      Period 7                        +/-40%
                      Period 8                        +/-40%

      6.4   Fairchild's share of a package and pin count module's installed
            equipment capacity will equal the previous National Assured Capacity
            for that module, plus that percentage of any excess capacity
            available in the package and pin count module equal to Fairchild's
            percentage of the currently utilized capacity in said module.
            Installed equipment capacity by package and pin count module is set
            forth herein at Exhibit C.

      6.5   One (1) work week after receipt of the Capacity Request, National
            shall provide Fairchild with a response to such Capacity Request,
            the "National Assured Capacity". The National Assured Capacity must
            guarantee the amount requested in Fairchild's latest Capacity
            Request, provided that any changes to Fairchild's latest Capacity
            Request are within the limits of Paragraph 6.3. National shall
            utilize its Best Efforts to comply with any requests by Fairchild
            for capacity above those which are permitted under Paragraph 6.3. In
            any case, National shall be obligated hereunder to provide Fairchild
            with the assembly starts guaranteed in the National Assured Capacity
            response. The initial National Assured Capacity response shall be
            the last response provided prior to the Effective Date. Set forth
            below are two examples of the foregoing:

            Example #1  The new Capacity Request is less than the last National 
                        Assured Capacity response.

      6.6   The timetable for the rolling eight fiscal period Capacity Request,
            the National Assured Capacity response, purchase order release and
            detailed Device level assembly starts request for the next fiscal
            period are set forth in Exhibit D hereto.

7.0   PURCHASE ORDERS

      7.1   All purchases and sales between National and Fairchild shall be
            initiated by Fairchild's issuance of written purchase orders sent by
            either first class mail or facsimile. By 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 assembly
            starts three (3) fiscal periods in the future. They shall state the
            product family, package and pin count, and shipping and invoicing
            instructions. National shall accept purchase orders through a
            written or electronic acknowledgment. Upon receipt of Fairchild's
            detailed Device level assembly starts request for the next fiscal
            period, National shall provide Fairchild with a Product delivery
            schedule either on a weekly basis as assembly is started or for the
            assembly starts for the entire fiscal period, as the Parties may
            agree. The purchase orders may utilize the first three (3) fiscal
            periods forecast in the eight period rolling forecast supplied
            pursuant to Section 6, as the embodiment of the purchase order for
            specifying the assembly starts by package and pin count.

      7.2   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.


                                      -10-
<PAGE>

      7.3   Consistent with standard practices of issuing specific Device level
            details of part numbers to be assembled on a weekly or periodic
            basis, Fairchild may unilaterally change the part number to be
            manufactured, provided that National agrees that the change does not
            negatively impact National's loadings and provided further that
            there is no change in the package and pin count to be used. A change
            that will negatively impact loading or alter the package and pin
            count may only be directed upon National'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 electronic data exchange, or
            other mutually satisfactory system.

      7.4   Fairchild shall request delivery dates which are consistent with
            National's reasonable lead times for each Device as indicated at the
            time Fairchild's purchase order is placed. Notwithstanding the
            foregoing, National shall utilize its Best Efforts to accommodate
            requests by Fairchild for quick turnarounds or "hot lots", which
            includes prototype lots. Hot lot cycle times shall be a fifty
            percent (50%) reduction of standard cycle time with a $2,000 lot
            charge.

      7.5   National may manufacture lots of any size which satisfy the
            requirements of effective manufacturing. However, Fairchild must
            place orders for full flow and prototype Products in minimum lot
            sizes of three thousand (3,000) Devices.

8.0   PRICING AND PAYMENT

      8.1   Set forth herein at Exhibit F is the forecasted volume of assembly
            services that Fairchild will purchase from National during the
            initial thirty-nine (39) fiscal periods (the "Forecast Volumes").
            The Forecast Volumes are for pricing purposes under this Section 8
            only and may vary in magnitude and mix in practice, whereupon the
            prices applicable to the revised magnitude and mix may also vary.

      8.2   The Parties hereby acknowledge that the prices for 


                                      -11-
<PAGE>

            assembly and test services to be provided by National to Fairchild
            as set forth herein are determined based on the collateral
            transactions and ongoing relationship between the Parties as
            expressed in the Purchase Agreement, Revenue Side Letter and
            corresponding Fairchild Foundry Services Agreement, Fairchild
            Assembly Services Agreement and Mil/Aero Wafer and Services
            Agreement, all of even date herewith between the Parties
            (collectively, the "Operating Agreements"). Set forth in Exhibit F
            hereto are the prices which Fairchild shall pay to National for
            standard assembly and test services hereunder during the first six
            (6) fiscal periods of this Agreement. The prices in Exhibit F for
            fiscal periods 7 through 39 are for information purposes only and
            are based on the Parties' best estimate of forecast volumes and
            projected costs.

      8.3   The methodology under which prices which Fairchild shall pay to
            National for standard assembly and test services hereunder after the
            first six (6) fiscal periods of this Agreement is set forth herein
            at Exhibit K.

      8.4   For purposes of Exhibit K, Fairchild, or any "Big 6" accounting firm
            designated by Fairchild, shall have reasonable rights, not more than
            twice per fiscal year, to audit the books and records of National
            relevant to the pricing terms of this Agreement in order to come to
            agreement with National with regard to National's actual
            manufacturing costs.

      8.5   Prices are quoted and shall be paid in U.S. Dollars. Such prices are
            on an FOB ship point basis. Payment terms are net thirty (30) from
            date of invoice. Miscellaneous services may be invoiced separately.

      8.6   Fairchild shall pay, in addition to the prices quoted or invoiced,
            the amount of any freight, insurance, special handling and duties.
            Fairchild shall also pay all sales, use, excise or other similar tax
            applicable to the sale of goods or provision of services covered by
            this Agreement, or Fairchild shall supply National with an
            appropriate tax exemption certificate.

      8.7   Quoted prices are based on the use of standard National processes
            and on the assumption that Fair-


                                      -12-
<PAGE>

            child's product is readily accommodated by National's
            assembly/handling equipment and processes. Any changes that must be
            made thereto shall result in additional charges to Fairchild that
            are mutually agreed to by the Parties.

      8.8   Unless otherwise noted, quoted prices for assembly shall include
            packing, marking and testing in accordance with the Specifications
            for Devices that are in production as of the Effective Date. For new
            Devices added after the Effective Date, pricing will reflect
            specifications and any special requirements for the Device, such as
            multi-insertion testing.

      8.9   Should yields below historical levels be directly attributable to
            Die, materials, processes or documentation provided by Fairchild,
            then Fairchild shall be charged for the full price of Devices begun
            in assembly, including handling, incurred by National in processing
            such units.

      8.10  Should Fairchild terminate any order prior to process completion,
            Fairchild shall be charged a prorated portion of the full price of
            such Device, subject to a negotiated adjustment, based on the
            process termination point, including handling incurred by National
            in processing the total quantity started in assembly.

      8.11  National may invoice Fairchild for complete or partial lots (kits).

      8.12  Fairchild shall in no event be required to pay prices in excess of
            those charged by National for other third party customers, for
            substantially similar services sold on substantially similar terms
            (e.g., volume, payment terms, manufacturing criteria, contractual
            commitments vs. spot buys, etc.). In the event National desires to
            perform services for other third party customers at such lower
            prices, National shall immediately notify Fairchild and Fairchild
            shall begin receiving the benefit of such lower price at the same
            time as such other third party customer. This Paragraph 8.12 shall
            not apply to the prices to be paid by Fairchild hereunder for the
            first twelve (12) fiscal periods of this Agreement, or if Fairchild
            fails to honor its fixed commitments under Section 6 and to the
            extent that such sales by National to third party customers are 


                                      -13-
<PAGE>

            only made in an attempt to make up for any underutilization of
            capacity thereby caused by Fairchild.

      8.13  For assembly and test services not reflected in Exhibit F, terms
            shall be on an individual purchase order basis at prices to be
            negotiated by the Parties using a methodology based on that set
            forth in Exhibit K.

9.0   DELIVERY; RESCHEDULING AND CANCELLATION

      9.1   National shall make reasonable and diligent efforts to deliver
            assembled and/or tested Devices on the delivery dates published to
            Fairchild. Any shipment made within +/- 3 days of the shipment
            date(s) published to Fairchild shall constitute timely shipment.

      9.2   All Devices delivered pursuant to the terms of this Agreement shall
            be suitably packed for shipment in Fairchild's specified containers,
            marked for shipment to Fairchild's address set forth in the
            applicable purchase order and delivered to a carrier or forwarding
            agent chosen by Fairchild. National shall not be responsible for
            delays in shipment resulting from Fairchild's failure to supply
            National with an adequate supply of Fairchild's specified
            containers. Should Fairchild fail to designate a carrier, forwarding
            agent or type of conveyance, National 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 Fairchild. Shipments will be subject to incoming inspection
            as set forth in Paragraph 5.1 above.

      9.3   Fairchild may, with National's prior written consent, reschedule
            delivery of any order of assembled and/or tested Devices once each
            fiscal period.

      9.4   Subject to the provisions of Section 6 hereof, Fairchild may cancel
            any purchase order at least two (2) weeks prior to the commencement
            of work by National without charge, provided that Fairchild
            reimburses National for the cost of any unique raw materials
            purchased after such purchase order has been placed, and provided
            further that National had provided Fairchild with a listing of
            materials it 


                                      -14-

            considers unique.

            enhancement programs throughout the term of this Agreement.

      10.2  National shall support Fairchild quality programs and shall supply
            to Fairchild reports and/or manufacturing data in standard National
            format that are in effect and which are required as of the Effective
            Date.

      10.3  National hereby warrants that the Facilities currently are, and will
            remain throughout the term of this Agreement, ISO9000 certified.

11.0  ON-SITE INSPECTION AND INFORMATION

      11.1  National shall allow Fairchild and/or Fairchild's customers to visit
            and evaluate the Facilities during normal business hours as part of
            established source inspection programs, it being understood and
            agreed between Fairchild and National that Fairchild must obtain the
            concurrence of National for the scheduling of all such visits, which
            such concurrence shall not be unreasonably withheld. It is
            anticipated that these visits will occur not more than once per
            quarter, on average.

      11.2  Upon Fairchild's written request, National will provide Fairchild
            with process control information, to include but not be limited to:
            SPC, yield and other detailed assembly and test quality and
            reliability data and associated analyses required to support
            Fairchild and Fairchild's customers' quality and reliability
            programs. Except for exigent circumstances, such requests shall not
            be made more than twice per year for a given category of
            information.

      11.3  Upon Fairchild's request and National's agreement which shall not be
            unreasonably withheld, National shall provide Fairchild engineers
            with access to the Facilities to the extent necessary to perform
            yield improvement and product management updates relevant to this
            Agreement. Fairchild's engineers 


                                      -15-
<PAGE>

            will comply with all applicable National regulations in force at the
            Facilities and Fairchild hereby agrees to hold National harmless for
            any damages or liability caused by any such Fairchild engineer,
            which are attributable to:

           (i)  the negligence or willful malfeasance of such engineer, and

          (ii)  any failure to comply with National's regulations in force at
                  the Facilities or with applicable law.

12.0  REPORTS AND COMMUNICATIONS

      12.1  Each Party hereby appoints a Program Manager whose responsibilities
            shall include acting as a focal point for the technical and
            commercial discussions between them related to the subject matter of
            this Agreement, to include monitoring within his or her respective
            company the distribution of Confidential Information received from
            the other Party and assisting in the prevention of the unauthorized
            disclosure of Confidential Information within the company and to
            third parties. The Program Managers shall also be responsible for
            maintaining pertinent records and arranging such conferences,
            visits, reports and other communications as are necessary to fulfill
            the terms and conditions of this Agreement. The names, addresses and
            telephone numbers of the Program Managers will be communicated
            between the Parties from time to time.

13.0  EXPORT CONTROL

      13.1  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.

      13.2  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, di-


                                      -16-
<PAGE>

            rectly or indirectly, any wafers, Die, Devices, technology or
            technical information received hereunder, that would be in
            contravention of any laws and regulations published by any United
            States government agency.

14.0  TERM AND TERMINATION

      14.1  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 (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, Fairchild 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. Fairchild will provide
            National with not less than ninety (90) days prior written notice of
            any such reduction.

      14.2  This Agreement may be terminated, in whole or in part, by one Party
            sending a written notice to the other Party of its election to
            terminate, 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 


                                      -17-
<PAGE>

                  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.

      14.3  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 National may continue to retain and use any
            rights or property belonging to Fairchild solely for the period
            necessary for it to finish manufacturing the currently forecasted
            National Assured Capacity and/or complete any production ramp-down
            activity. Nothing in this Section 14 is intended to relieve either
            Party of any liability for any payment or other obligations existing
            at the time of termination.

      14.4  The provisions of Sections 13, 15 and Paragraphs 5.2, 5.3, 16.5 and
            16.8 shall survive the termination of this Agreement for any reason.

15.0  CONFIDENTIALITY

      15.1  For purposes of this Agreement, "Confidential Information" shall
            mean all proprietary information, including Fairchild and/or
            National 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.

      15.2  Except as may otherwise be provided in the Technology Licensing and
            Transfer Agreement between the Parties of even date herewith, 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, 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 


                                      -18-
<PAGE>

            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.

      15.3  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.

      15.4  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 expense 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.

            disaster, act of God, war, embargo, riot, labor dispute,
            unavailability of raw materials or utilities (provided that such

            Should either of the Parties waive any provision or right under this
            Agreement, such waiver shall not be construed as constituting a

      16.7  SEVERABILITY: If any provision of this Agreement or the application
            thereof to any situation or circumstance shall be invalid or

            enforceable to the fullest extent.

      16.11 PUBLIC ANNOUNCEMENT: Prior to the closing of the transactions
            contemplated under the Purchase Agreement, neither Fairchild nor

            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

            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

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

      16.13 BINDING EFFECT: This Agreement and the rights and obligations

CONFIDENTIAL  PORTIONS OF THIS DOCUMENT HAVE BEEN DELETED AND FILED SEPARATELY
WITH  THE  SECURITIES  AND  EXCHANGE  COMMISSION  PURSUANT  TO A  REQUEST  FOR
CONFIDENTIAL TREATMENT

      THIS MIL/AERO WAFER AND SERVICES AGREEMENT ("Agreement") is dated and made
effective this 11th day of March, 1997 (the "Effective Date") by and between
NATIONAL SEMICONDUCTOR CORPORATION, a Delaware corporation, having its principal
place of business at 2900 Semiconductor Drive, Santa Clara, California
95052-8090 ("National") and [FAIRCHILD SEMICONDUCTOR CORPORATION], a Delaware
corporation, having its principal place of business at 333 Western Avenue, South
Portland, Maine 04106 ("Fairchild"). National and/or Fairchild may be referred
to herein as a "Party" or the "Parties" as the case may require.

                             W I T N E S S E T H:

      WHEREAS, the Parties have entered into a certain Asset Purchase Agreement
(hereinafter referred to as the "Purchase Agreement") under which Fairchild is
acquiring certain of the assets of National's Logic, Memory and Discrete Power
and Signal Technologies Business Units as historically conducted and accounted
for (including Flash Memory, but excluding Public Networks, Programmable
Products and Mil/Aero Logic Products) (the "Business"); and

      WHEREAS, pursuant to the transactions contemplated in the Purchase
Agreement, Fairchild is acquiring National's manufacturing facilities in South
Portland, Maine (excluding the eight-inch fab and related facilities); West
Jordan, Utah; Penang, Malaysia; and Cebu, the Philippines; and

      WHEREAS, after the closing of the transactions contemplated by the
Purchase Agreement Fairchild will own and operate the Facilities; and

      WHEREAS, National, using proprietary processes, has been manufacturing
silicon wafers containing certain integrated circuits intended for use in
Mil/Aero products at the Facilities and performing associated services; and

      WHEREAS, National is conveying to Fairchild certain intellectual property
rights pursuant to the Technology Licensing and Transfer Agreement between
National and Fairchild, of even date herewith; and

      WHEREAS, National and Fairchild desire to enter into an agreement under
which Fairchild will continue to provide certain manufacturing services and
Fairchild Products to National following the closing of the transactions
contemplated by the Purchase Agreement; and

<PAGE>

      WHEREAS, National and Fairchild recognize that the prices National shall
pay to Fairchild for Products manufactured pursuant to this Agreement are
determined based on the collateral transactions and ongoing relationship between
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
               applicable objective. Such obligation, however, does not require
               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.

        1.3    "Confidential Information" shall have the meaning set forth in
               Paragraph 19.1 below.

               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-
<PAGE>

               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-
<PAGE>

               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-
<PAGE>

               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-
<PAGE>

               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-
<PAGE>

               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].

9.0     PRICES AND PAYMENT

        9.1    The Parties hereby acknowledge that, as part of the collateral
               transactions contemplated under the Purchase Agreement and
               ongoing relationship between the Parties, they have entered into
               the Revenue Side Letter under which National has agreed to
               provide a minimum revenue of [CONFIDENTIAL INFORMATION OMITTED
               AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION]

               be invoiced separately.

        9.5    National shall pay, in addition to the prices quoted or invoiced,
               the amount of any freight, insurance, special handling and
               duties. National shall also pay all sales, use, excise or other
               similar tax applicable to the sale of goods covered by this
               Agreement, or National shall supply Fairchild with an appropriate
               tax exemption certificate.

10.0    OTHER MANUFACTURING SERVICES

        10.1   Fairchild shall continue to provide such services to National at
               the same level of support that was in effect as of the Effective
               Date. This specifically includes S-level processing including SEM
               step coverage, as outlined in SP34061 and Wafer Lot Acceptance as
               outlined in SP3402.

        10.2   At National's request, Fairchild will perform Wafer sort and test
               services based on sort and test programs prepared, owned and
               otherwise proprietary to National. Towards that end, National
               shall supply 


                                      -12-

               with specific prices as set forth in Exhibit G, and specific sort
               times as set forth in Exhibit B.

        10.3   Fairchild will supply Mil/Aero Wafers in compliance to commercial
               critical electrical test parametrics (PCM data) according to
               Product Specifications. Existing sort minimum yield assurance
               specifications as defined in Section 13 will be guaranteed to
               National. In the event that National changes any test program
               forcing function or limit specification of a Mil/Aero sort
               program existing on the Effective date, Fairchild will only
               guarantee Wafer acceptance to the PCM data.

        10.4   National will continue to have rights to the MCT Program Writer
               (PW) software. National will be provided copies of all associated
               VAX libraries as well as all support programs (MRL) relating to
               MCT and PCMCT testers. Fairchild will provide whatever assistance
               is necessary in loading and bringing the source code on-line on
               National's systems. This project will be completed by May 31,
               1997, after which date National will no longer have access to the
               Fairchild PW VAX system. Services provided by Fairchild after May

               Efforts to have this project completed by May 31, 1997. If, due
               to circumstances beyond National's control, the system cannot be
               assembled and brought on-line prior to May 31, 1997, Fairchild
               will provide support free of charge for a reasonable period of
               time. Otherwise support required beyond May 31, 1997 will be
               charged at $100 per hour.

        10.6   National shall have non-exclusive rights to the VHDL model of the

                     capacitances, sheet resistivities of all conducting layers,
                     parasitic capacitances for diffused areas, and so forth,
                     including additional elements or devices intended for
                     mixed-signal applications.
               (d)   Process cross sections, if not already available at
                     National.
               (e)   Sufficient sizing and PCM information to assure the
                     integrity of masks ordered in support of products to be
                     manufactured.
               (f)   Yield models plus applicable current and forecast
                     parameters such as Ys and Do for those models.

               This information should be in the form of at least one controlled
               paper copy or electronic access to a controlled copy. National,
               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-
<PAGE>

               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-
<PAGE>

               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-
<PAGE>

               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.

        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-
<PAGE>

               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-
<PAGE>

                     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;

               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

               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-
<PAGE>

               (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-
<PAGE>

               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-
<PAGE>

               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.

20.0    REPORTS AND COMMUNICATIONS

        20.1   Each Party hereby appoints a Program Manager whose
               responsibilities shall include acting as a focal point for the
               technical and commercial discussions between them related to the
               subject matter of this Agreement, to include monitoring within
               his or her respective company the distribution of Confidential
               Information received from the other Party and assisting in the
               prevention of the unauthorized disclosure of Confidential
               Information within the company and to third parties. The Program
               Managers shall also be responsible for maintaining pertinent
               records and arranging such conferences, visits, reports and other
               communications as are necessary to fulfill the terms and
               conditions of this Agreement. The names, addresses and telephone
               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-
<PAGE>

               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

               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-
<PAGE>

               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
               this Agreement.

        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

               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-

               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
<PAGE>

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.

                                LETTER OF INTENT

THIS LETTER OF INTENT is dated _______________ of August, 1991, by and between
NATIONAL SEMICONDUCTOR CORPORATION, a Delaware Corporation, having a principal
place of business at 2900 Semiconductor Drive, Santa Clara, California
95052-8090 (hereinafter "NSC") and THINK-O ELECTRIC COMPANY, a Japanese
corporation, having a principal place of business at 150 Kinoko, Ibara-City,
Okayama, 715 Japan (hereinafter "TEC"). NSC and/or TEC may be referred to herein
as a "party" or the "parties" as the case may require.

                                   WITNESSETH:

      WHEREAS, NSC and TEC have entered into preliminary discussions concerning
the creation of a business relationship between the parties; and

      WHEREAS, NSC and TEC desire to record and memorialize the substance of
those discussions in order to construct a framework from which a final binding
agreement can be negotiated.

      NOW, THEREFORE, in furtherance of the premises the parties hereto set
forth the following:

1.    NSC shall purchase discrete semiconductor dice and/or wafers, and will
      consider the purchase of other semiconductor materials and piece parts,
      from TEC on a preferred supplier basis.

2.    TEC shall supply such materials to NSC as a preferred customer with
      special pricing and guaranteed production capacity.

3.    Should TEC discrete semiconductors be successfully qualified by NSC and

      and conditions of sale, then NSC shall agree to commence purchasing a
      minimum of [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
      THE SECURITIES AND EXCHANGE COMMISSION]wafers, or dice equivalent, per
      [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
      SECURITIES AND EXCHANGE COMMISSION]from TEC.  Since the parties
      acknowledge that NSC requirements for discrete semiconductors may
      increase during the [CONFIDENTIAL INFORMATION OMITTED AND FILED
      SEPARATELY WITH THE SECURITIES AND EXCHANGE 

<PAGE>

      COMMISSION]period following the signing of a final agreement by the
      parties, TEC agrees that it shall, at NSC's request, make available to NSC

 Combined Total                                          Finished    Resistor
  Wafers/Month      Diodes       Zeners      Trans.       Trans.      Trans.
  ------------      ------       ------      ------       ------      ------

[CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
                             EXCHANGE COMMISSION]

      Diode and zener prices do not include front bump or back metal. Transistor
      prices do not include back metal, but shall sample probing. All prices
      include production masks and incidental tooling expenses. NSC shall supply
      mask masters. The listed prices are also based on yields of [CONFIDENTIAL

                                LETTER OF INTENT

THIS LETTER OF INTENT is dated _______________ of August, 1991, by and between
NATIONAL SEMICONDUCTOR CORPORATION, a Delaware Corporation, having a principal
place of business at 2900 Semiconductor Drive, Santa Clara, California
95052-8090 (hereinafter "NSC") and THINK-O ELECTRIC COMPANY, a Japanese
corporation, having a principal place of business at 150 Kinoko, Ibara-City,
Okayama, 715 Japan (hereinafter "TEC"). NSC and/or TEC may be referred to herein
as a "party" or the "parties" as the case may require.

                                   WITNESSETH:

      WHEREAS, NSC and TEC have entered into preliminary discussions concerning
the creation of a business relationship between the parties; and

      WHEREAS, NSC and TEC desire to record and memorialize the substance of
those discussions in order to construct a framework from which a final binding
agreement can be negotiated.

      NOW, THEREFORE, in furtherance of the premises the parties hereto set
forth the following:

1.    NSC shall purchase discrete semiconductor dice and/or wafers, and will
      consider the purchase of other semiconductor materials and piece parts,
      from TEC on a preferred supplier basis.

2.    TEC shall supply such materials to NSC as a preferred customer with
      special pricing and guaranteed production capacity.

3.    Should TEC discrete semiconductors be successfully qualified by NSC and
      should the parties agree on price, quality, delivery and other terms and
      conditions of sale, then NSC shall agree to commence purchasing a minimum
      of [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
      SECURITIES AND EXCHANGE COMMISSION] wafers, or dice equivalent, per
      month from TEC. Since the parties acknowledge that NSC
      requirements for discrete semiconductors may increase during the
      two year period following the signing of a final agreement
      by the parties, TEC agrees that it shall, at NSC's request, make available
      to NSC up to [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
      THE SECURITIES AND EXCHANGE COMMISSION] discrete semiconductor wafers per
      month. Depending upon TEC performance and semiconductor market 
      conditions, the parties agree that this schedule can be extended
      and that the quantity of wafers to be delivered thereunder can be
      increased up to [CONFIDENTIAL INFORMATION OMITTED AND
<PAGE>

      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] or more per
      month.

4.    The parties agree to cooperate and take all reasonable steps necessary to
      resolve any problems that may arise with regard to performance, price,
      quality or delivery.

5.    The initial prices to NSC for TEC wafers shall be follows:

                                                                       Bias
 Combined Total                                          Finished    Resistor
  Wafers/Month      Diodes       Zeners      Trans.       Trans.      Trans.
  ------------      ------       ------      ------       ------      ------

[CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
                             EXCHANGE COMMISSION]

      Diode and zener prices do not include front bump or back metal. Transistor
      prices do not include back metal, but shall sample probing. All prices
      include production masks and incidental tooling expenses. NSC shall supply
      mask masters. The listed prices are also based on yields of [CONFIDENTIAL
      INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
      COMMISSION] percent for diodes and [CONFIDENTIAL INFORMATION OMITTED AND
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] percent for
      transistors.

6.    Initial deliveries by TEC shall be [CONFIDENTIAL INFORMATION OMITTED AND
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION]after receipt
      of order. Following deliveries will be based upon a [CONFIDENTIAL
      INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
      COMMISSION] rolling forecast supplied by NSC and updated monthly.

7.    The parties agree to review pricing annually.

8.    This Letter of Intent shall not be a binding commitment upon either party,
      but shall instead serve as a basis for good faith negotiations between NSC
      and TEC leading to a final binding contract. The parties agree to strive
      to execute such a contract not later than September 30, 1991.

9.    The final contract shall be administered on behalf of TEC by Torex
      Semiconductor LTD., TEC's international operations management company.
<PAGE>

10.   Neither party shall publicize or otherwise disclose the terms of this
      relationship, this Letter of Intent, or the final agreement, without the
      prior written approval of the other party.

            IN WITNESS WHEREOF, the parties have had this Letter of Intent
executed by their respective authorized officers on the day and date first
written above.

- -     All wafers are tested at T85, 100 spots/wafer

- -     A minimum of [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
      THE SECURITIES AND EXCHANGE COMMISSION] wafer yield to the BV, leakage,
      Vbe portion of the specification for the target bin yield except when it
      is determined by both parties that the HFE target will cause the BV
      distribution to fall below the specification. An engineering plan to
      improve the BV distribution for these high HFE devices will be developed
      and reviewed in three periods. Along with the electrical yields in
      general. Examples are as follows:

      SECURITIES AND EXCHANGE COMMISSION] lot average yield to the HFE bin with
      no wafer in the lot having less than[CONFIDENTIAL INFORMATION OMITTED AND
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] yield to the
      HFE bin.

- -     For HFE bin targets where the HFE range is less than 2:1 or there is a
      high HFE requirement, the lot average yield for these bins is a minimum
      [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES
      AND EXCHANGE COMMISSION] with no wafer in the lot yielding less than
      [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES
      AND EXCHANGE COMMISSION]. These bins will be identified on the test
      programs.

- -     NSC and Torex agree to review these yields after a device has run for
      three periods to see if a change to the yield accept limit is needed. The
      target goal for the HFE bins is [CONFIDENTIAL INFORMATION OMITTED AND
      FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION].

DIODE YIELD ACCEPTANCE
- ----------------------

All wafers are tested at T85 as follows:
<PAGE>

- -     5 wafers/lot sampled; 100 spots/wafer

      * If the yield is [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY
      WITH THE SECURITIES AND EXCHANGE COMMISSION]%, the lot is shipped to Cebu

      * If the 1 or more wafers have [CONFIDENTIAL INFORMATION OMITTED AND FILED
      SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION], 5 more wafers in
      the lot are tested 
      2nd group of 5 wafers sampled; 100 spots/wafer

      * If all of these wafers [CONFIDENTIAL INFORMATION OMITTED AND FILED
      SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION], the lot is
      shipped to Cebu

      * If one of more wafers yield [CONFIDENTIAL INFORMATION OMITTED AND FILED
      SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION], the remaining
      wafers in the lot are tested

Any wafer with yield [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION] is scrapped at Think-O. Wafers with
yield between [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION] can be shipped to Cebu as long as the total
number of wafers in this yield range does not exceed [CONFIDENTIAL INFORMATION
OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] of the
shipment. This is to be reviewed in 30 days from today with a target yield goal
of [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES
AND EXCHANGE COMMISSION] or greater.

                                SUPPLY AGREEMENT

CONFIDENTIAL PORTIONS OF THIS DOCUMENT HAVE BEEN DELETED AND FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT

            THIS SUPPLY AGREEMENT ("Agreement") is dated and made effective this
      20th day of January, 1996 (the "Effective Date") by and between National
      Semiconductor Corporation, a Delaware corporation, having its principal
      place of business at 2900 Semiconductor Drive, Santa Clara, California

      Leong, 18 Jalan Perak, 50450 Kuala Lumpur, Malaysia ("DCI Sdn Bhd"). NSC
      and/or DCI Sdn Bhd may be referred to herein as a "party" or the "parties"
      as the case may require.

                              W I T N E S S E T H:

            WHEREAS, Malaysian Pacific Industries Berhad ("MPI"), on the one
      hand, and Dyna-Craft, Inc., a California corporation, Dynacraft Sdn Bhd, a
      Malaysian corporation, and Dynacraft Asia Pacific Sdn Bhd, a Malaysian
      corporation (collectively "DCI"), on the other hand, and NSC have entered
      into that certain Purchase and Sale Agreement (the "Purchase and Sale
      Agreement") dated November 9, 1995, under which DCI is selling certain
      assets relating to its business of manufacturing and selling lead frames
      for integrated circuits and other semiconductor devices (the "Business")
      to MPI; and

            WHEREAS, MPI has assigned its rights with respect to certain of the
      Purchased Assets to DCI Sdn Bhd, as provided in Section 3.4 of the
      Purchase and Sale Agreement; and

            WHEREAS, DCI has heretofore been a major supplier of lead frames
      products and services to NSC; and

            WHEREAS, NSC and DCI Sdn Bhd desire to enter into an agreement under
      which DCI Sdn will continue to sell lead frames to NSC following the
      closing of the transactions contemplated by the Purchase and Sale
      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:
<PAGE>

1.0   DEFINITIONS

1.1   "Confidential Information" shall mean all proprietary information which is
      directly or indirectly disclosed by either party to the other hereunder,
      regardless of the form in which it is disclosed, which if furnished in
      written or other tangible form is clearly marked as being confidential, or
      if orally or visually furnished is identified as being confidential when
      disclosed and is later confirmed as such in a writing submitted to the
      receiving party within thirty (30) days after such oral or visual
      disclosure.

1.2   "Lead frame" shall mean a thin piece of copper, or other form of metal,
      alloy used as the mounting pad and external leads for silicon chips in
      semiconductor devices.

1.3   "Period" shall mean that accounting and planning interval based upon NSC's
      fiscal year which is divided into four (4) equal quarters, each of which
      consists of three (3) periods. The first two periods of each quarter are
      of four (4) weeks duration, while the third period is five (5) weeks in
      duration. Each of these periods, whether of four (4) or five (5) weeks
      duration, shall be referred to herein as a Period.

1.4   All other terms that are utilized in this Agreement and are defined in the
      Purchase and Sale Agreement shall have the same meaning as provided in the
      Purchase and Sale Agreement.

2.0   SCOPE

2.1   Subject to the terms and conditions of this Agreement, during the initial
      one (1) year term of this Agreement NSC will purchase from DCI Sdn Bhd,
      and DCI Sdn Bhd shall sell to NSC, a total number of lead frames whose
      aggregate value shall not be less than [CONFIDENTIAL INFORMATION OMITTED
      AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] of the
      net dollar value of lead frames purchased by NSC from DCI during NSC's
      1995 fiscal year.

      a. NSC, at its option, may identify on an attachment to this Agreement
      certain lead frame types (limited to those lead frames being produced by
      DCI for NSC as of May 31, 1995), in respect of which DCI Sdn Bhd shall
      supply NSC's requirements. These required supplies, if any, shall be
      included as part of the [CONFIDENTIAL INFORMATION OMITTED AND FILED
      SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] dollar volume
      commitment set forth hereinabove in this Paragraph 2.1.
<PAGE>

      b. During its first year of this Agreement, DCI Sdn Bhd shall, at a
      minimum, meet quality and delivery standards which were in effect at the
      time of the Closing. By the end of such one (1) year period, DCI Sdn Bhd
      shall be required to have met and continue to maintain throughout any
      remaining term of this Agreement, industry standard requirements for
      quality and delivery.

2.2   Should NSC request, DCI Sdn Bhd shall cooperate and provide to NSC, at
      NSC's expense, a second set of designs and drawings for tooling for lead
      frame types supplied to NSC hereunder. Subject to the provisions of
      Paragraph 2.1 above, NSC shall be permitted to purchase lead frames from
      second source or alternate suppliers.

2.3   DCI Sdn Bhd shall, during the term of this Agreement, maintain sufficient
      manufacturing capacity to produce and deliver to NSC its requirements
      referenced in Paragraph 2.1 above.

2.4   Providing DCI Sdn Bhd can meet or exceed competitive criteria established
      in the marketplace, NSC shall offer DCI Sdn Bhd the opportunity to sell to
      NSC new and/or additional lead frame types not being supplied to NSC by
      DCI Sdn Bhd as of May 31, 1995.

2.5   This Agreement shall consist of two parts. The first shall be that portion
      (the "Main Body") which governs the overall terms and conditions for the
      sale of lead frames from DCI Sdn Bhd to NSC. The Main Body consists of
      Sections 1 through 14. The second part of this Agreement shall consist of
      separate Schedules for each operating unit of NSC purchasing lead frames
      hereunder. Each Schedule shall set forth applicable prices,
      specifications, inspection and acceptance criteria and and other
      operational and technical issues particular to that operating unit. Unless
      specifically set forth otherwise in Schedule, in the event of any
      inconsistency between the Main Body and a Schedule hereto, the terms and
      conditions of the Main Body shall prevail, provided, however, that nothing
      in such Schedules shall be deemed to override the provisions of Section 6
      hereof.

3.0   PRODUCTION CONTROL AND PLANNING

3.1   All planning herein will be done under NSC's accounting calendar.

3.2   NSC shall provide DCI Sdn Bhd with a six Period rolling forecast (the
      "Forecast") for lead frames. The Forecast is due by the last workday of
      the second (2nd) week of each Period for the following six Periods and
      shall be a firm commitment by NSC according to the following schedule:
<PAGE>

      Period 1 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 2 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 3 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 4 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 5 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 6 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]

3.3   DCI Sdn Bhd shall provide a commitment (the "Commitment") to each Forecast
      by the third (3rd) week of the Period immediately preceding the first
      (1st) Period of the Forecast. The Commitment shall be a firm commitment by
      DCI Sdn Bhd according to the following schedule:

      Period 1 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 2 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 3 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 4 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
      Period 5 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE

      Period 6 - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
                  SECURITIES AND EXCHANGE COMMISSION]
<PAGE>

3.4   The Forecast does not constitute a purchase order and nothing contained
      therein shall authorize DCI Sdn Bhd to manufacture and ship lead frames to
      NSC before receiving a formal purchase order from NSC. Notwithstanding the
      foregoing, nothing shall prevent NSC from placing purchase orders in
      excess of the Forecast for lead frames, in which event DCI Sdn Bhd agrees
      to use its reasonable best efforts to supply NSC in accordance therewith.

3.5   The parties agree to cooperate in implementing an electronic data
      interchange in order to facilitate production planning and ordering
      hereunder.

4.0   CHANGES NOTIFICATION

4.1   If DCI Sdn Bhd proposes to make any change in materials, manufacturing
      locations and/or processes used in the Business as of the Closing Date of
      the Purchase and Sale Agreement, it shall provide NSC written notice
      thereof, in which event NSC shall have the right conduct qualification as
      it deems necessary. In no event shall DCI Sdn Bhd provide lead frames to
      NSC hereunder other than in strict accordance with the specifications set
      forth in the Schedules or such amendments to said specifications as NSC
      shall have approved in writing.

5.0   ACCEPTANCE/QUALIFICATION/RAMP UP

5.1   DCI Sdn Bhd shall utilize its best efforts to complete qualification of
      new lead frame types requested by NSC as soon as possible.

5.2   NSC shall be responsible for specifying and performing any qualification
      testing deemed necessary.

5.3   DCI Sdn Bhd shall provide NSC with a preliminary ramp up schedule for new
      lead frame types, which may be subject to subsequent reduction in the
      event abnormal problems are encountered by DCI Sdn Bhd with yields,
      process, capacity support, quality/reliability or other product or process
      features.

6.0   PRICING, DELIVERY AND PAYMENT TERMS

6.1   The parties expressly agree that except as is set forth in Paragraph 6.2,
      below, with respect to the [CONFIDENTIAL INFORMATION OMITTED AND FILED

      5.2   In consideration for the provision by WSI of TECHNICAL ASSISTANCE,
            NSC shall pay a technical support fee of [CONFIDENTIAL INFORMATION
            OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
            COMMISSION] per month for the period during which WSI is providing
            TECHNICAL ASSISTANCE specified in Section 4.3, which payments are
            not to exceed in total [CONFIDENTIAL INFORMATION OMITTED AND FILED
            SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION].

      5.3   In consideration for the license granted by NSC to WSI under Section
            3.4, WSI shall devote reasonable technical resources during the term
            of this Agreement to the development of a 16 Meg EPROM and related
            process improvements. In the event WSI desires to cease its
            development effort on a 16 Meg EPROM, it shall so notify
<PAGE>

            NSC and WSI shall thereafter, through the term of this Agreement and
            any extension thereof, pay to NSC a royalty of [CONFIDENTIAL
            INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
            EXCHANGE COMMISSION] of the NET SALES by WSI of products
            manufactured by NSC on the EPROM PROCESS or manufactured for WSI by
            a third-party foundry pursuant to the license granted to WSI under
            Section 3.4 of this Agreement.

      5.4   All royalty payments required hereunder shall be made quarterly in
            arrears, within [CONFIDENTIAL INFORMATION OMITTED AND FILED
            SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] of the end
            of each of paying PARTY's fiscal quarters and shall be accompanied
            by a report setting forth the NET SALES of LICENSED PRODUCTS and the
            manner in which the amount of the royalty payment was calculated.
            Each PARTY shall have the right, in confidence and upon reasonable
            notice, to have a mutually acceptable third party accounting firm
            inspect the other PARTY's books and records to determine compliance
            with this Section 5.0.

      5.5   Except as otherwise provided in this Agreement, each PARTY shall pay
            all of its own expenses incurred in order to perform its obligations
            under this Agreement.

6.0   STOCK PURCHASE AGREEMENT

      6.1   In further consideration for the licenses granted by WSI to NSC
            under Sections 3.1, and 3.2 and 3.3, for the transfer by WSI of
            TECHNICAL INFORMATION, and for the provision by WSI of TECHNICAL
            ASSISTANCE, NSC shall make a Nine Million Dollar ($9,000,000) equity
            investment in WSI in substantially equal installments at three
            closings under the terms and conditions set forth in the Stock
            Purchase Agreement attached hereto as Appendix D, which is being
            entered into by the PARTIES simultaneously with this Agreement.

            Notwithstanding anything to the contrary contained herein, this
            Agreement shall not be effective for any purpose unless and until
            the First Closing under the Stock Purchase Agreement (as defined
            therein) has occurred.

7.0   SUPPLY OF FINISHED PRODUCT AND WAFERS TO WSI

      7.1   NSC agrees to supply to WSI LICENSED PRODUCTS in the form of
            finished products or as dice in wafer form, and to supply other
            products manufactured on the EPROM PROCESS in parametrically
            tested-wafer form, subject to the terms and conditions set forth in
            this Section 7.0, which shall control over any other terms and
            conditions in conflict therewith set forth in any other document.

      7.2   For LICENSED PRODUCTS, NSC agrees to supply finished products in
            packaged and tested form to WSI beginning not more than thirteen
            (13) weeks after
<PAGE>

            QUALIFICATION of the relevant LICENSED PRODUCT (subject to the
            possible ramp-up constraints described in Section 7.4). Such
            products shall be marked with the WSI logo and such other markings
            as agreed by the PARTIES. Alternatively, upon the request of WSI,
            NSC will supply LICENSED PRODUCT as dice in wafer form beginning not
            more than nine (9) weeks after QUALIFICATION of the relevant
            product. For LICENSED PRODUCTS, NSC shall provide and pay for (i)
            development wafer processing needed for QUALIFICATION of such
            products, with quantities determined by agreement of the PARTIES,
            (ii) mask tooling for LICENSED PRODUCTS, (iii) scribeline test chip
            tooling costs, and (iv) other production costs associated with the
            QUALIFICATION of LICENSED PRODUCTS.

      7.3   For WSI products which are not licensed to NSC, NSC shall supply
            product to WSI in the form of parametrically tested wafers only, and
            only on the condition that the products can be manufactured on the
            EPROM PROCESS, and provided further that WSI pays the costs of all
            masks and tooling for such products. NSC shall be liable for no
            engineering costs on non-LICENSED PRODUCTS beyond those required to
            meet the parametric acceptance criteria.

            The quantity of such non-LICENSED PRODUCTS shall not exceed
            [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
            SECURITIES AND EXCHANGE COMMISSION] percent of the total wafers
            manufactured by NSC for WSI during any calendar quarter.

      7.4   Pursuant to Sections 7.2 and 7.3, NSC shall supply such quantities
            as are ordered by WSI up to the monthly volumes set forth in the
            following schedule:

      Quarter 1: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                 THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 2: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                 THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 3: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                 THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 4: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                 THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 5: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                 THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 6: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                 THE SECURITIES AND EXCHANGE COMMISSION]
<PAGE>

      Quarter 7:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Thereafter: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]

            The capacity defined for "Quarter 1" in this Section 7.4 will be
            available for shipments to WSI starting [CONFIDENTIAL INFORMATION
            OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
            COMMISSION] after NSC has completed QUALIFICATION of the 27C010LS.
            However, as a result of "learning-curve" constraints in new assembly
            and test flows, both PARTIES recognize that the finished goods
            manufacturing cycle time for LICENSED PRODUCTS immediately after
            QUALIFICATION of a LICENSED PRODUCT may be longer than the
            [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
            SECURITIES AND EXCHANGE COMMISSION] contemplated by this Section
            7.0. Both PARTIES agree to use their best efforts to assist
            improvement of such longer cycle times as quickly as possible.

      7.5   In consideration for NSC making available to WSI the wafer capacity
            set forth in Section 7.4, WSI guarantees to purchase the following
            minimum quantities:

      Quarter 1:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 2:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 3:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 4:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 5:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 6:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
      Quarter 7:  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]
<PAGE>

      Thereafter: [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION]

            These minimum guarantees shall be subject to annual renegotiation
            (but in no event to less than [CONFIDENTIAL INFORMATION OMITTED AND
            FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] per
            month) provided, however, that the available capacity committed by
            NSC in Section 7.4 shall be correspondingly adjusted to an amount
            equal to [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
            THE SECURITIES AND EXCHANGE COMMISSION] the minimum guaranteed
            amount. Notwithstanding these minimum guarantees, WSI shall have the
            option to terminate the foundry provisions of this Section 7.0 in
            accordance with the notice requirements of Section 7.16.

      7.6   The prices to be paid by WSI for LICENSED PRODUCTS shall be
            determined according to the schedules and formulae set forth in
            Appendix E.

      7.7   For non-LICENSED PRODUCTS, NSC shall initially be obligated to
            deliver only parametrically tested wafers, processed to NSC
            commercial production standards. Thereafter, the wafers shipped to
            WSI for non-LICENSED PRODUCTS shall be subject to the ACCEPTANCE
            CRITERIA set forth in Appendix G. The prices to be charged for such
            wafers will be based on WSI's total equivalent wafer consumption,
            with the price during any month determined by averaging the wafer
            production value of LICENSED PRODUCTS and other products sold to
            WSI, according to the following schedule:

            (i)   First [CONFIDENTIAL INFORMATION
                  OMITTED AND FILED SEPARATELY
                  WITH THE SECURITIES AND EXCHANGE
                  COMMISSION]  Wafers per month - [CONFIDENTIAL
            INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
            EXCHANGE COMMISSION]

            (ii)  Wafers [CONFIDENTIAL INFORMATION

                  WITH THE SECURITIES AND EXCHANGE
                  COMMISSION]  per month - [CONFIDENTIAL
            INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
            EXCHANGE COMMISSION]

                  OMITTED AND FILED SEPARATELY
                  WITH  THE SECURITIES AND EXCHANGE
                  COMMISSION]  per month - [CONFIDENTIAL
            INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
            EXCHANGE COMMISSION]
<PAGE>

            (iv)  Wafers [CONFIDENTIAL INFORMATION OMITTED AND FILED
            SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] per month
            - [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
            THE SECURITIES AND EXCHANGE COMMISSION] 

            (v) Wafers [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY
            WITH THE SECURITIES AND EXCHANGE COMMISSION] and up per month -
            [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
            SECURITIES AND EXCHANGE COMMISSION]

            For non-LICENSED PRODUCTS, NSC shall not be obligated to start any
            production lots containing fewer than [CONFIDENTIAL INFORMATION
            OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
            COMMISSION] wafers. Further, NSC shall not be obliged to carry more
            than [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
            SECURITIES AND EXCHANGE COMMISSION] different non-LICENSED PRODUCTS
            in work-in-process ("WIP") at any one time, provided, however, that
            this limitation is based on the assumption that wafer fabrication
            cycle time is between [CONFIDENTIAL INFORMATION OMITTED AND FILED
            SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] weeks, and
            if that cycle time is consistently exceeded the PARTIES shall
            negotiate a modification of this eight product limit.

            Since all non-LICENSED PRODUCTS are custom with respect to WSI, once
            wafers have started, WSI will be obligated to accept and pay for
            completed wafers or NSC stated WIP costs.

      7.8   Special wafer fabrication charges:

            (i)   wafers produced to 883C standard shall be subject to a
                  surcharge of [CONFIDENTIAL INFORMATION OMITTED AND FILED
                  SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] per
                  wafer. 883C wafers will be limited to a maximum of
                  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION] percent of the total
                  wafers manufactured for WSI.

            (ii)  Quick turnaround lots, which are run in approximately 2.5
                  times theoretical cycle time, shall be limited to
                  [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH
                  THE SECURITIES AND EXCHANGE COMMISSION] wafers. The
                  availability of quick turnaround lot starts is subject to
                  allocation among all users in the line, and they shall be
                  billed at [CONFIDENTIAL INFORMATION OMITTED AND FILED
<PAGE>

                  SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] the
                  wafer price prevailing at the time the wafers are started.

      7.9   NSC shall have the option of subcontracting to third parties the
            wafers manufactured for WSI hereunder, provided that said
            subcontracted wafers satisfy the WSI ACCEPTANCE CRITERIA specified
            in Appendix G.

      7.10  WSI shall utilize purchase orders as the mechanism for short term
            forecasting. Each month, WSI shall place a purchase order for its
            best estimate of its requirements, by product type, for the sixth
            month hence. All purchase orders with delivery dates of less than
            three months are firm, and may not be altered.

      7.11  Purchase orders outside the three month window may be changed
            according to the following schedule:

            Delivery date                       Aggregate Change

      [CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY WITH THE
      SECURITIES AND EXCHANGE COMMISSION]

            Because different product types may be included, the aggregate
            changes shall be evaluated on the basis of wafer starts to serve WSI
            needs within any given month.

      7.12  WSI will assist NSC in all long term planning, providing long term
            forecasts of expected requirements for finished goods, dice and
            wafers. These forecasts will be required in March and September of
            each year, supporting NSC's capacity forecasting cycles.

      7.13  In the event of a shortfall in wafer capacity for the EPROM PROCESS,
            NSC shall support the WSI guarantees according to Paragraph 7.5
            above. Additional capacity shall be allocated in the following
            manner:

            (i)   NSC shall use capacity up to the guarantees defined for WSI in
                  Paragraph 7.5.

            (ii)  Remaining capacity will be allocated in proportion to the hard
                  backlog (described in equivalent wafers) of the PARTIES.

            Capacity allocations shall be defined in wafers, and each PARTY will
            have the freedom, within the constraints of timing for wafer starts,
            to define which products shall be manufactured with their available
            capacity.

      7.14  In the event of a shortfall in NSC's final test capacity for EPROMS,
            NSC shall have the option of subcontracting final test or of
            shipping packaged but untested units to WSI at a cost determined in
            accordance with Appendix E. NSC shall advise WSI of
<PAGE>

            such untested shipments no less than [CONFIDENTIAL INFORMATION
            OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
            COMMISSION] weeks prior to the date that product will be sealed by
            NSC.

      7.15  All shipments to WSI of finished products and wafers shall be
            governed by NSC's standard terms and conditions of sale, except as
            modified herein. A copy of such terms and conditions is attached
            hereto as Appendix F, and in the event of any conflict between such
            terms and this Agreement, this Agreement shall control. Payment
            shall be made by WSI within thirty [CONFIDENTIAL INFORMATION OMITTED
            AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION]of
            the date of NSC's invoice. In the event of non-payment or delayed
            payment by WSI, NSC shall have the right to suspend performance
            hereunder, place WSI on "credit hold" or take other appropriate
            actions immediately notwithstanding the 60-day cure period provided
            in Section 12.2 for other breaches of this Agreement.

      7.16  If WSI desires to stop purchasing wafers or finished product from
            NSC, the following ramp-down schedule shall apply:

                                                Percentage of Outs For
            Months After Notice                 Month Notice is Given

      7.17  NSC shall have the right to cease production of finished products or
            wafers for WSI at any time prior to the termination of this
            Agreement on the following conditions:
<PAGE>

      7.17.1 NSC must give WSI not less than [CONFIDENTIAL INFORMATION OMITTED
             AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION]
             written notice of its intention to cease such production.

      7.17.2 NSC shall not be entitled to issue such notice until [CONFIDENTIAL

             wafers to WSI pursuant to this Section 7.0.

      7.17.3 Upon its receipt of notice from NSC under Section 7.17.1, WSI shall
             be required to confirm, not later than [CONFIDENTIAL INFORMATION

             INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
             EXCHANGE COMMISSION] the maximum quantity that could otherwise be
             ordered by WSI during the notice period.

      7.18  In the event WSI terminates this Agreement pursuant to Section 12.2
            or NSC ceases production for WSI pursuant to Section 7.17, WSI shall
            have the right to disclose NSC TECHNICAL INFORMATION delivered to
            WSI hereunder to one or more third parties for the sole purpose of
            having such third parties provide WSI with design, layout, foundry,
            assembly and testing services relating to semiconductor products,
            provided that such disclosures are made under terms and provisions
            which protect the confidentiality of the disclosed information upon
            the terms, and for a period which is not less that, contained in
            this Agreement. WSI shall also have rights to the tooling used by
            NSC in the manufacture of product of WSI, and NSC shall provide WSI
            reasonable technical assistance and consultation to assist such
            foundry in qualifying its process for WSI.

8.    PROGRAM MANAGEMENT

      8.1   Within fifteen (15) days after signature of this Agreement, the
            PARTIES shall appoint a Program Management Committee of no more than
            six persons, comprised of three representatives from each PARTY, at
            least one of which shall be an engineer qualified in technical
            matters related to the LICENSED PRODUCTS. Each PARTY shall designate
            one of its representatives to this Committee as Program Manager,
            whose primary responsibility shall be to act as a focal point for
<PAGE>

            technical and commercial discussions between the PARTIES related to
            the subject mater of this Agreement.

      8.2   The Program Management Committee shall meet not less than once a
            month for the initial six months of this Agreement, and not less
            than quarterly thereafter. Meetings shall be held alternately at
            WSI's site in Fremont and NSC's site in Santa Clara, unless
            otherwise agreed. The Program Managers of each PARTY shall establish
            the agenda in advance of each meeting.

9.0   TECHNICAL COOPERATION

      9.1   By mutual agreement, the parties may add to the number of LICENSED
            PRODUCTS by adding additional products to Appendix A. In the event
            such additional products are developed solely by WSI, NSC shall pay
            to WSI the product transfer fee specified in Section 5.1(ii) and
            such products shall be subject to the royalty obligations of Section
            5.1(iii).

      9.2   In the event WSI develops a NEW VERSION, it shall transfer to NSC
            the TECHNICAL INFORMATION required under Section 4.2, and the
            following additional terms shall apply:

            9.2.1. If the NEW VERSION does not exceed the performance levels set
                   forth on Appendix I, NSC shall have the option to immediately
                   add the NEW VERSION to Appendix A, in which case the NEW
                   VERSION will be governed by Section 9.1.

            9.2.2 If the NEW VERSION does exceed the performance levels set
                  forth on Appendix I, NSC shall have the right to add the NEW
                  VERSION as an Appendix A LICENSED PRODUCT [CONFIDENTIAL
                  INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES
                  AND EXCHANGE COMMISSION] after first silicon on the NEW
                  VERSION is shipped by NSC to WSI, provided that NSC shall have
                  the right to deliver customer samples only until [CONFIDENTIAL
                  INFORMATION OMITTED AND FILED SEPARATELY WITH THE SECURITIES
                  AND EXCHANGE COMMISSION] after shipment of such first silicon
                  to WSI. Notwithstanding the foregoing time restrictions on
                  NSC's ability to ship samples or production units of the NEW
                  VERSION, should NSC demonstrate, to the reasonable
                  satisfaction of WSI, that an EPROM competitor of NSC's has
                  announced, sampled or shipped production units of an EPROM
                  that is competitive in performance to the NEW VERSION, then
                  NSC shall have the right to announce equivalent information
                  and ship equivalent samples or production units.

      9.3   In order to continue expansion of the product family, the PARTIES
            may agree that NSC shall design specified additional EPROMS, all of
            which shall be
<PAGE>

            manufacturable on the EPROM PROCESS, with the technical assistance
            and cooperation of WSI. These COOPERATIVE PRODUCTS shall be offered
            for sale to WSI under the provisions and pricing methods of Section
            7.0 applicable to LICENSED PRODUCTS at the time they are released to
            production by NSC.

      9.4   COOPERATIVE PRODUCTS shall not be subject to either a product
            transfer fee or a royalty.

      9.5   Notwithstanding assistance from any NSC engineer in designing the
            WSI 27C020LS product, the PARTIES recognize that WSI will own the
            27C020LS and that the 27C020LS will be a LICENSED PRODUCT and not a
            COOPERATIVE PRODUCT.

10.0  FUTURE AGREEMENTS

      10.1  WSI and NSC desire to work together on the joint development of the
            next generation of EPROM products and processes. The PARTIES
            therefore agree to negotiate in good faith with the goal of entering
            into a mutually satisfactory CO-DEVELOPMENT AGREEMENT setting forth
            the terms and conditions of such joint development work as promptly
            as possible after the execution of this Agreement. However, failure
            by the PARTIES to negotiate a CO-DEVELOPMENT AGREEMENT will not
            constitute a material breach under this Agreement.

      10.2  WSI has indicated to NSC its interest in acquiring license rights to
            manufacture and sell certain NSC products on terms and conditions
            similar to those set forth in this Agreement. The PARTIES therefore
            agree to negotiate in good faith with the goal of entering into a
            mutually satisfactory LICENSING AGREEMENT under which NSC would
            license WSI to manufacture an and sell up to five mutually-agreed
            NSC products on terms and conditions similar to those of this
            Agreement. However, failure by the PARTIES to negotiate a LICENSING
            AGREEMENT will not constitute a material breach under this
            Agreement.

11.0  CONFIDENTIALITY

      11.1  Each PARTY acknowledges that the other may, from time to time,
            reveal certain confidential business or technical information which
            will be CONFIDENTIAL INFORMATION. Each PARTY agrees that it will not
            use in any way for its own account or the account of any third
            party, not disclose to any third party, except pursuant to this
            Agreement, any such CONFIDENTIAL INFORMATION revealed to it by the
            other PARTY. Each PARTY shall take every reasonable precaution to
            protect the confidentiality of the CONFIDENTIAL INFORMATION of the
            other PARTY. Each PARTY shall use the same standard of care in
            protecting the CONFIDENTIAL INFORMATION of the other PARTY as it
            normally uses in
<PAGE>

            protecting its own trade secrets and proprietary information, or a
            higher standard of care if reasonable under the circumstances.

      11.2  Notwithstanding any other provisions of this Agreement, no
            information received by a PARTY hereunder shall be CONFIDENTIAL
            INFORMATION if said information is:

            11.2.1 published or otherwise made available to the public other
                   than by a breach of this Agreement,

            11.2.2 furnished to a PARTY by an independent third party without
                   restriction on its dissemination,

            11.2.3 approved for release in writing by the PARTY designating said
                   information as CONFIDENTIAL INFORMATION,

            11.2.4 known to or independently developed by the PARTY receiving
                   CONFIDENTIAL INFORMATION hereunder without reference to or
                   use of said CONFIDENTIAL INFORMATION, or

            11.2.5 disclosed to a third party by the PARTY transferring said
                   information hereunder without restriction on its subsequent
                   disclosure and use by said third party.

      11.3  Disclosure of any CONFIDENTIAL INFORMATION by a PARTY hereto 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 to obtain a protective order requiring that the
            CONFIDENTIAL INFORMATION so disclosed be kept in confidence and used
            only for the purpose for which such order was issued.

      11.4  Either PARTY may disclose CONFIDENTIAL INFORMATION of the other
            PARTY for the sole purpose of exercising the "have made" rights
            granted in Section 3.0 of this Agreement, provided that such
            disclosures are made under terms and provisions which protect the
            confidentiality of the disclosed information upon the terms, and for
            a period which is not less than that, contained in this Agreement.

12.0  TERM AND TERMINATION

      12.1  Unless otherwise terminated as herein provided, this Agreement shall
            continue in full force and effect for a period of five (5) years
            from the date hereof, and thereafter shall continue on a
            year-to-year basis unless the PARTY wishing to terminate provides
            the other PARTY not less than twelve (12) months written notice of
            its intent not to renew this Agreement.
<PAGE>

      12.2  This Agreement may be terminated by either PARTY for material breach
            of this Agreement if such breach has not been cured within sixty
            (60) days after written notification of such breach; provided,
            however, that this Agreement may not be terminated if the breaching
            PARTY has provided within such sixty (60) day period evidence of
            good-faith effort and progress toward curing the breach, in which
            case this agreement may not be terminated unless the breach has not
            been cured within ninety (90) days of written notification of the
            breach.

      12.3  This Agreement may be terminated by either PARTY with immediate
            effect in the event the other PARTY files for liquidation under
            Chapter 7 of the United States Bankruptcy Code, or a prior Chapter
            11 proceeding in which the other PARTY is the debtor is converted to
            a Chapter 7 proceeding.

      12.4  In the event that a proceeding for corporate reorganization under
            chapter 11 of the United States Bankruptcy Code is filed by or
            against a PARTY, or a Receiver or Trustee is appointed for a PARTY,
            or a PARTY makes an assignment for the benefit of creditors, the
            other PARTY may immediately suspend performance of its obligations
            hereunder (other than royalty obligations in excess of amounts owed
            to such PARTY) until such time as it receives reasonable assurances
            of such PARTY's ability and intent to fully perform such PARTY's
            obligations hereunder. If a condition referred to in this Section
            12.4 continues for more than one (1) year, the other PARTY may at
            its option terminate this Agreement upon written notice to such
            PARTY.

      12.5  In the event of termination of this Agreement, other than
            termination under Section 12.2, the licenses and rights to royalties
            granted hereunder shall survive such termination and all other
            rights granted hereunder shall cease (except for rights accruing to
            one PARTY by reason of the other PARTY's performance hereunder prior
            to the effective date of termination).

      12.6  In the event of termination under Section 12.2, the licenses and
            rights to royalties shall continue except as follows:

            (i)   the licenses granted by WSI to NSI shall terminate if the
                  Agreement is terminated by WSI for a material breach by NSC of
                  its obligations under Sections 5.0, 6.0 or 7.17 of this
                  Agreement, and

            (ii)  the obligations of NSC to pay royalties to WSI shall terminate
                  if the Agreement is terminated by NSC for a material breach by
                  WSI of its obligations under Section 4.0

      12.7  Notwithstanding any other provisions of this Agreement, the
            confidentiality provisions of Section 11.0 shall survive any
            termination of this Agreement.
<PAGE>

      12.8  IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR INCIDENTAL
            OR CONSEQUENTIAL DAMAGES UPON TERMINATION OF THIS AGREEMENT FOR ANY
            REASON.

13.0  INVENTIONS

      13.1  All discoveries, improvements and inventions conceived in the
            performance of this Agreement by NSC personnel shall be the sole and
            exclusive property of NSC and NSC shall retain any and all rights to
            file at its sole discretion and patent applications thereon.

      13.2  All discoveries, improvements and inventions conceived in the
            performance of this Agreement by WSI personnel shall be the sole and
            exclusive property of WSI and WSI shall retain any and all rights to
            file at its sole discretion any patent applications thereon.

      13.3  All discoveries, improvements and inventions conceived jointly by
            NSC and WSI personnel in the performance of this Agreement shall be
            jointly owned by NSC and WSI with each PARTY having the undivided
            right to exploit and grant licenses in respect of such inventions
            and any patents arising therefrom without accounting to the other
            PARTY. In the event of a joint invention, the PARTIES shall have the
            responsibility for preparing and filing a patent application on the
            invention in the United States and foreign countries and the PARTIES
            agree that each will bear one-half of the actual out-of-pocket
            expenses associated with obtaining and maintaining such patents. In
            the event one PARTY elects not to seek or maintain patent protection
            for any joint invention in any particular country or not to share
            equally in the expenses thereof with the other PARTY, that other
            PARTY shall have the right to apply for or maintain such patent
            protection at its own expense in such country and shall have full
            control over the prosecution and maintenance thereof, even though
            title to any patent resulting therefrom shall be jointly owned.

14.0  PATENT INDEMNITY

      WSI agrees to defend any suit or proceeding brought against NSC if it is
      based on a claim that a LICENSED PRODUCT or other WSI product manufactured
      by NSC under this Agreement constitutes an infringement of any patent,
      trademark, copyright, mask work right, trade secret or other proprietary
      right of a third party, if notified promptly in writing and given full and
      complete authority, information and assistance (at WSI's expense) for the
      defense of same. WSI shall pay all damages and costs, including attorneys'
      fees, therein awarded against NSC, but WSI shall not be responsible for
      any compromise made without its written consent. Notwithstanding anything
      herein to the contrary, however, WSI's total liability under this Section
      14.0 shall not exceed the total amount of license fees and product
      transfer fees paid by NSC to WSI pursuant to Section 5.1

15.0  NONSOLICITATION OF EMPLOYEES
<PAGE>

      During the term of this Agreement and for a period of one year thereafter,
      neither PARTY will solicit or induce any employee of the other PARTY who
      is or has been engaged in the transfer of TECHNICAL INFORMATION or in
      rendering TECHNICAL ASSISTANCE to become an employee or consultant of such
      PARTY.

16.0  PUBLICITY

      The PARTIES will agree on the content of a press announcement related to
      the relationship contemplated by this Agreement. Except as otherwise
      provided in this Section 16.0, neither PARTY shall publicize or otherwise
      disclose the terms of this Agreement without the prior approval of the
      other PARTY, which approval shall not be unreasonably withheld. This
      provision shall not affect the right of NSC or WSI to disclose under
      confidentiality and use restrictions, such terms of this Agreement as are
      reasonably necessary to disclose for purposes of providing information of
      the type customarily requested by customers and prospective customers in
      the ordinary course of doing business, and of seeking financing, bank
      credit or the like. Both PARTIES shall remain free to disclose the
      existence of the Agreement, that NSC is a foundry for WSI products, and
      the origin and design authorship of products produced or licensed under
      this Agreement.

17.0  ASSIGNMENT

      This Agreement and the rights and obligations rising hereunder shall be
      binding upon and inure to the benefits of the PARTIES and to their
      respective successors and assigns, provided that one PARTY shall not
      assign any of its rights or privileges hereunder without the prior written
      consent of the other PARTY. Notwithstanding the above, this Agreement may
      be assigned by either PARTY pursuant to a merger, consolidation or sale of
      all or substantially all of the assets of a PARTY, provided that the
      successor agrees to be bound by the terms of this Agreement; provided,
      however, that the rights granted in Section 7.0 shall not be assignable to
      or assumable by any third party which meets either of the following
      criteria: (i) annual semiconductor sales of more than $1 Billion, or (ii)
      any other company which NSC can demonstrate to the reasonable satisfaction
      of WSI is unlikely to adequately protect CONFIDENTIAL INFORMATION or
      observe the license restrictions set forth in this Agreement. In the event
      NSC refuses to consent to assignment of the rights granted in Section 7.0
      on the basis of (ii) above, then NSC shall nevertheless provide WSI the
      "lifetime buy" opportunity on the same basis as provided in Section 7.17,
      except that the notice period of Section 7.17.1 shall be reduced to twelve
      (12) months and the "lifetime buy" quantity in Section 7.17.3 shall be
      limited to not more than two (2) times the maximum quantity that could
      otherwise be ordered during the notice period.

18.0  WAIVER

      No failure or delay on the part of either PARTY in the exercise of any
      power, right or privilege arising hereunder shall operate as a waiver
      thereof, nor shall any single or partial
<PAGE>

      exercise of any such power, right or privilege preclude other or further
      exercise thereof or of any other right, power or privilege.

19.0  INTEGRATION

      This Agreement and the Stock Purchase Agreement attached hereto as
      Appendix D constitute the entire agreement and understanding between the
      PARTIES with respect to the subject matter of this Agreement and integrate
      all prior discussions and proposals (whether oral or written) between them
      related to the subject matter hereof. No modification of any of the terms
      of this Agreement shall be valid unless in writing and signed by a duly
      authorized officer of each PARTY.

20.0  SEVERABILITY

      If any provision of this Agreement is for any reason found to be
      ineffective, unenforceable or illegal, such condition shall not affect the
      validity of enforceability of any of the remaining portions hereof;
      provided, further, the PARTIES shall negotiate in good faith to replace
      any ineffective, unenforceable or illegal provision with an effective
      replacement as soon as is practical.

21.0  FORCE MAJEURE

      Neither PARTY shall be liable in damages or have the right to terminate
      for any delay or default in performing hereunder where such delay or
      default is caused by conditions beyond the control of the delaying or
      defaulting PARTY, including but not limited to acts of God, government
      restrictions, continuing domestic or international problems such as wars
      or insurrections, strikes, fires, floods, work stoppages and embargoes;
      provided, however, that either PARTY shall have the right to terminate
      this Agreement upon thirty (30) days prior written notice if the delay or
      default of the other PARTY due to any of the above-mentioned causes
      continues for a period of six (6) months.

22.0  COUNTERPART ORIGINALS

      This Agreement is being executed simultaneously in two (2) counterparts,
      each of which shall be deemed an original but both of which together
      constitute one and the same instrument.

23.0  NO PARTNERSHIP OR AGENCY CREATED

      Nothing contained herein or done in pursuant of this Agreement shall
      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.

24.0  CHOICE OF LAW
<PAGE>

      This Agreement and the performance of the PARTIES hereunder shall be
      construed in accordance with and governed by the laws of the State of
      California.

25.0  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 this Agreement.

26.0  EXPORT CONTROL

      Each PARTY hereby represents and warrants to the other PARTY that unless
      prior authorization is obtained or a general license is available from the
      United States Government, such PARTY shall not knowingly:

      (i)   Export or re-export, directly or indirectly, any technical data (as
            defined in Part 379 of the Administration Regulations of the United
            States Department of Commerce) received from the other PARTY
            hereunder, or

      (ii)  Disclose such technical data for use in or export or re-export,
            directly or indirectly, any direct product of such technical data,
            to any destination or country to which the export or re-export or
            release of such technical data or export or re-export of the direct
            products of such technical data is prohibited by the laws or
            regulations of the United States. These assurances are furnished by
            each PARTY in compliance with Part 379 (Technical Data) of the
            export Administration Regulations of the United States Department of
            Commerce.

      (iii) Each PARTY hereby further agrees to obtain any necessary export
            license or other documentation prior to exportation of any products
            or technical data acquired from the other PARTY under this
            Agreement. Accordingly, such PARTY shall not sell, export,
            re-export, transfer, divert or otherwise dispose of any such product
            directly or indirectly to any person, firm or entity, or country of
            countries, prohibited by the laws or regulations of the United
            States. Further, each PARTY shall give notice of the need to comply

                     WITH NATIONAL SEMICONDUCTOR CORPORATION

      This Agreement is made and dated as of April 27, 1990, among WaferScale
Integration, Inc., a California corporation with its principal office located at
47280 Kato Road, Fremont, California 94538 (the "Company"), and National
Semiconductor Corporation, a Delaware corporation with its principal office
located at 2900 Semiconductor Drive, Santa Clara, California 95052 (the
"Purchaser").

                                    SECTION 1

                      Authorization and Sale of the Shares

[Comment1]

      1.1 Authorization of the Shares. The Company has or, as of the First
Closing Date (as hereinafter defined) will have authorized the sale and issuance
of 391,781 shares of its Series C Convertible Preferred Stock (the "Series C
Preferred") and 2,291,585 shares of its Series D Convertible Preferred Stock
(the "Series D Preferred") having the rights, restrictions, privileges and
preferences as set forth in the Fourth Restated Articles of WaferScale
Integration, Inc., as amended, attached to this Agreement as Exhibit A-1 as
further amended by the Amendment to Fourth Restated Articles of Waferscale
Integration, Inc. in the form attached as Exhibit A-2 to this Agreement (the
"Amendment to Articles") (together, the "Articles"). Shares of the Company's
preferred stock of any series now existing or hereafter issued shall be
collectively referred to as "Preferred Stock".

      1.2 Sale of the Shares. Subject to the terms and conditions hereof, the
Company will issue and sell to the Purchaser and the Purchaser will purchase
from the Company an aggregate of 391,781 shares of Series C Preferred and
2,291,585 shares of Series D Preferred (the "Shares") at a purchase price of two
dollars and fifty cents ($2.50) per share of Series C Preferred and three
dollars and fifty cents ($3.50) per share of Series D Preferred. The Shares
shall be purchased and sold in three substantially equal installments at three
closings as described below.

      1.3 Lower Priced Securities. Notwithstanding anything to the contrary set
forth in this Agreement, if the Company issues any securities prior to the Third
Closing (other than securities excluded from the definition of "Additional
Shares of Common" under Section 5(d)(i)(4) of the Articles, and the Series C
Preferred contemplated by this Agreement) at a price per share
<PAGE>

(determined in accordance with Section 5(d)(v)(1) of the Articles) of less than
$3.35 subject to adjustments for stock splits, reverse stock splits, stock
dividends, reclassifications and the like ("Lower Price"), the Purchaser shall
be entitled to purchase, at a price per share equal to the Lower Price, at any
Closing after such issuance, instead of the Shares to be purchased by the
Purchaser at such Closing, that number of the securities that may be purchased
for the remaining consideration contemplated by Section 2.1(b) and/or Section
2.1(c), as appropriate.

      1.4 Share Reserves. In the event the Company issues securities triggering
the provisions of Section 1.3, the Company shall, prior to such issuance, take
all such actions as are necessary to ensure that the required number of shares
of such securities and Common Stock are properly reserved and available for
issuance to Purchaser under the provisions of Section 1.3.

                                    SECTION 2

                             Closing Dates; Delivery

      2.1 Closing Dates. Each of the closings of the purchase and sale of the
Shares hereunder (collectively the "Closings" and individually a "Closing")
shall be held at the offices of Ware & Freidenrich, 400 Hamilton Avenue, Palo
Alto, California 94301, on the dates as hereinafter provided (collectively the
"Closing Dates"):

            (a) The first Closing for the purchase and sale of 130,594 shares of
Series C Preferred and 763,862 shares of Series D Preferred (the "First
Closing") shall be held on the first business day following the date on which
verbal confirmation is received that the Amendment to Articles has been filed by
the California Secretary of State, or on such other date as the Purchaser and
the Company may agree (the "First Closing Date").

            (b) The second Closing for the purchase and sale of 130,594 shares
of Series C Preferred and 763,862 shares of Series D Preferred (the "Second
Closing") shall be held on a date (the "Second Closing Date") within five (5)
business days after the qualification of the 27COlOLS at the Purchaser's wafer
foundry in accordance with the Licensing and Manufacturing Agreement of even
date herewith between the Purchaser and the Company (the "Licensing Agreement").

            (c) The third Closing for the purchase and sale of 130,593 shares of
Series C Preferred and 763,861 shares of Series D Preferred (the "Third
Closing") shall be held on a date (the "Third Closing Date") within five (5)
business days after the qualification of the 27CO40LS at the Purchaser's wafer
foundry in accordance with the Licensing Agreement.

      2.2 Delivery. Subject to the terms of this Agreement, at each Closing the
Company will deliver to the Purchaser two stock certificates registered in the
Purchaser's name representing the number of shares of Series C Preferred and
Series D Preferred purchased by the Purchaser at

purchase price multiplied by the number of shares being purchased at such
Closing, by check or wire transfer.

                                    SECTION 3

                  Representations and Warranties of the Company

      Subject only to and except as disclosed by the Company in the Schedule of
Exceptions attached as Exhibit B to this Agreement, the Company hereby
represents and warrants to the Purchaser as follows:

      3.1 Organization and Standing; Restated Articles and By-Laws. The Company
is a corporation duly organized and validly existing under the laws of the State
of California and is in good standing under such laws. The Company has requisite
corporate power to own and operate its properties and assets, and to carry on
its business as presently conducted. The Company is not qualified to do business
in any foreign jurisdiction, and the operation of the Company's business,
including the ownership or leasing of any property or the employment of any
person outside of California, does not presently require such qualification. The

                           Investment Representations

      4.1 Investment. This Agreement is made with the Purchaser in reliance upon
the Purchaser's representation to the Company, which by its acceptance hereof
the Purchaser hereby confirms, that the Shares to be received by the Purchaser
will be acquired for investment for the Purchaser's own account, and not with a
view to the sale or distribution of any part thereof, and that the Purchaser has
no present intention of selling, granting participation in, or otherwise
distributing the same. By executing this Agreement, the Purchaser further
represents that the Purchaser does not have any contract, undertaking,
agreement, or arrangement with any person to sell, transfer, or grant
participations to such persons, or to any third person, with respect to any of
the Shares or any Conversion Stock. The Purchaser understands that the Shares
are not, and any Conversion Stock at the time of issuance may not be, registered
under the Securities Act of 1933 (the "Securities Act") because the sale
provided for in this Agreement and the issuance of securities hereunder is
exempt from registration under the Securities Act pursuant to section 4(2)
thereof, and that the Company's reliance on such exemption is predicated on the
Purchaser's representations set forth herein.

      4.2 Experience and Information. The Purchaser represents that it is
experienced in evaluating high technology companies such as the Company, is able
to fend for itself in the transactions contemplated by this Agreement, has such
knowledge and experience in financial and


                                     - 10 -
<PAGE>

business matters as to be capable of evaluating the merits and risks of its
investment, and has the ability to bear the economic risks of its investment.
The Purchaser further represents that it has carefully reviewed the Financial
Statements and this Agreement, including all exhibits and appendices thereto and
hereto, and that it has had, during the course of the transaction and prior to
its purchase of its Shares, the opportunity to ask questions of ' and receive
answers from, the Company through its officers and key employees concerning the
terms and conditions of the offering and to obtain additional information (to
the extent the Company possessed such information or could acquire it without
unreasonable effort or expense) necessary to verify the accuracy of any
information furnished to it or to which it had access. Notwithstanding the
foregoing, any such investigation by Purchaser shall not affect Purchaser's
right to rely on the representations and warranties made by the Company in
Section 3 of this Agreement.

      4.3 Rule 144. The Purchaser understands that the Shares (and any
Conversion Stock) may not be sold, transferred, or otherwise disposed of without
registration under the Securities Act or an exemption therefrom, and that in the
absence of an effective registration statement covering the Shares (or the
Conversion Stock) or an available exemption from registration under the
Securities Act, the Shares (and any Conversion Stock) must be held indefinitely.
In particular, the Purchaser is aware that the Shares (and any Conversion Stock)
may not be sold pursuant to Rule 144 promulgated under the Securities Act unless
a.11 of the conditions of that Rule are met. Among the conditions for use of
Rule 144 is the availability of current information to the public about the
Company, unless the shares have been held for three years (Rule 144(k)). Such
information is not now available and the Company has no present plans to make
such information available. The Purchaser represents that, in the absence of an
effective registration statement covering the Shares (or any Conversion Stock),
the Purchaser will sell, transfer, or otherwise dispose of the Shares (or any
Conversion Stock) only in a manner consistent with the Purchaser's
representations set forth herein and then only in accordance with the provisions
of Section 4 hereof.

      4.4 Restrictions on Transferability4.4 Restrictions on Transferability.
The Shares shall not be transferable except upon the conditions specified in
this Section 4, which conditions are intended to insure compliance with the
provisions of the Securities Act of 1933. The Purchaser will cause any proposed
transferee of the Shares held by the Purchaser to agree to take and hold such
securities subject to the provisions and upon the conditions specified in this
Section 4.

      4.5 Restrictive Legend. Each certificate representing the Shares, (ii) the
Conversion Stock and (iii) any other securities issued in respect of the Shares
or the Conversion Stock upon any stock split, stock dividend, recapitalization,
merger, consolidation or similar event, shall (unless otherwise permitted by the
provisions of Section 4.6 below) be stamped or otherwise imprinted with a legend
in the following form (in addition to any legend required under applicable state
securities laws):

      THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
      1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE,


                                     - 11 -
<PAGE>

      TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS THERE IS AN
      EFFECTIVE REGISTRATION STATEMENT UNDER THAT ACT COVERING THESE SECURITIES,
      THE TRANSFER IS MADE IN COMPLIANCE WITH RULE 144 PROMULGATED UNDER THAT
      ACT OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE
      SECURITIES WHICH IS REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT
      SUCH REGISTRATION IS NOT REQUIRED.

Certificates representing securities that bear the legend above are referred to
below as "Restricted Securities".

      4.6   Notice of Proposed Transfers.

            (a) Prior to any proposed transfer of any Restricted Securities
(other than under circumstances described in Section 9 hereof), the Purchaser
shall give written notice to the Company of the Purchaser's intention to effect
such transfer, describing the manner and circumstances of the proposed transfer
in reasonable detail.

            (b) The notice provided for in Section 4.6(a) above shall be
accompanied (except in transactions in compliance with Rule 144) by either (i) a
written opinion of legal counsel (who shall be reasonably satisfactory to the
Company) addressed to the Company and reasonably satisfactory in form and
substance to the Company's counsel, to the effect that the proposed transfer of
the Restricted Securities may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission to the effect
that the distribution of such securities without registration will not result in
a recommendation by the staff of the Commission that action be taken with
respect thereto, whereupon the Purchaser shall be entitled to transfer such
Restricted Securities in accordance with the terms of the notice delivered by
the Purchaser to the Company. Each certificate evidencing the Restricted
Securities transferred as above provided shall bear the appropriate restrictive
legend set forth in Section 4.5 above, except that such certificate shall not
bear such restrictive legend if the opinion of counsel referred to above is to
the further effect that such legend is not required in order to establish
compliance with any provisions of the Securities Act.
