              submitted the order) upon delivery.

4. NON-CONFORMING SHIPMENTS.

    4.1. Reporting of Claims.

              Product or is otherwise non-conforming in a manner
              discoverable upon reasonable inspection (such as, by way of
              illustration, broken wafers), such non-conformity will be
              reported in writing to Seller as soon as possible and in any
              event no later than thirty (30) days after the date Products
              are delivered to the carrier at Seller's facilities. In all
              other cases, the non-conformity shall be reported in writing
              no later than ninety (90) days after such delivery date. Any

              shall be deemed waived.

    4.2. Remedies for Non-Conforming Shipments.

              Seller's sole obligation with respect to shipments

              Seller's expense) or to issue a credit to SC or SCOA, as
              the case may be, in the amount of the price paid for such
              Products with interest calculated at the rate specified in
              Section 2.3 from the date of payment to the date of
              credit. This paragraph states the exclusive remedy of
              Sumitomo and Purchaser with respect to non-conforming
              shipments. After acceptance of any shipment the sole
              remedies for defects in such shipment shall be as provided
              in the warranty provisions of this Agreement.

    4.3. Compliance with Instructions.

              In addition to such other duties as may be imposed by law,
              Sumitomo and Purchaser will comply with all of Seller's
              reasonable instructions regarding rejected goods. If
              Sumitomo or Purchaser incurs any expenses in complying
              with such instructions, including without limitation
              shipping expenses incurred in returning any rejected goods
              to Seller, Seller shall reimburse such expenses promptly
              upon receipt of a written request therefor.

          (b) This warranty is extended only to Sumitomo and
              Purchaser and does not constitute a warranty to any

              part from improper use or application, and Seller

              hundred sixty (360) days after the date Products are
              delivered to the carrier at Seller's facilities. If

          (d) Seller's sole obligation with respect to Products
              determined not to meet the terms of this warranty
              shall be, at its option, to replace such Products or
              to issue a credit or refund in the amount of the
              price received by Seller for the Products. This
              paragraph states the exclusive remedy against Seller
              with respect to breach of the warranty given herein
              or other alleged defects in the Products.

          (e) This Section 5.1, as limited by Section 5.2 and other
              applicable terms and conditions of this Agreement,
              shall survive the expiration or any termination of
              this Agreement with respect to Products purchased
              prior to such expiration or termination.

    5.2. Warranty Disclaimer.

              THE WARRANTY IN SECTION 5.1 ABOVE IS GIVEN IN LIEU OF ALL
              OTHER WARRANTIES, WHETHER ORAL OR WRITTEN, EXPRESS OR
              IMPLIED, OR IMPOSED BY STATUTE OR OTHERWISE. ALL IMPLIED
              WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE AND
              MERCHANTABILITY ARE EXPRESSLY DISCLAIMED BY SELLER.

   to this Agreement, or the termination of this Agreement, or arising
   out of or alleged to have arisen out of breach of this Agreement or
   the use or performance of any Products, even if advised of the
   possibility of such damages. This limitation applies regardless of
   whether such damages are sought based on breach of contract,
   warranty, negligence, strict liability or other legal theory.

7. CONFIDENTIAL INFORMATION

              shall be identified at the time of disclosure as
              "confidential" by marking, or in the case of oral
              disclosures, shall be confirmed as such in writing within
              thirty (30) days following the oral disclosure.  However,
              if not so identified, the receiving party before making
              use of any such information that could reasonably be
              assumed to be Confidential Information for any purpose,
              other than the performance of this Agreement, shall
              inquire of the disclosing party as to the status of such
              information and shall designate and treat the same as
              Confidential Information if so requested.

7.2. Confidentiality Obligations.

          (a) Each party agrees to maintain received Confidential
              Information in confidence and not to use such Confidential
              Information for any purpose other than the performance of
              this Agreement.  Neither party shall disclose any
              Confidential Information without the prior written
              approval of the disclosing party, except as required to
              comply with any order of a court or any applicable rule,
              regulation or law of any jurisdiction or as provided in
              Section 9.1.  In the event that a receiving party is
              required by judicial or administrative process to disclose
              Confidential Information of the disclosing party, it shall
              promptly notify the disclosing party and to the extent
              permitted by the circumstances allow the disclosing party
              a reasonable time to oppose such process.

          (b) Each party shall protect Confidential Information of the
              other by using the same degree of care, but not less than
              a reasonable degree of care, to prevent unauthorized
              disclosure or use as that party uses to protect its own
              confidential information of like nature. Within each
              party, Confidential Information shall be disclosed only to
              employees to whom disclosure is reasonably necessary to
              the performance of this Agreement. Each party shall limit
              the number of copies made of any item of received
              Confidential Information.

          (c) Each party shall appropriately notify each employee, agent
              or consultant to whom any disclosure of received
              Confidential Information is made and shall obtain their
              agreement that they will maintain Confidential Information
              in confidence in accordance with the provisions set forth
              herein. Each party represents and warrants to the others
              that its employees, agents and consultants to whom any
              disclosure of received Confidential Information is made
              shall be subject to a valid, binding and enforceable
              agreement to maintain such Confidential Information in
              confidence in accordance with the provisions set forth
              herein.

7.3. Survival.

              The obligations of confidentiality set forth in this
              Article 7 shall continue for so long as the Confidential
              Information continues to come within the definition
              thereof set forth in Section 7.1 and shall survive the
              expiration or any termination of this Agreement.

              the other parties" shall mean, with respect to termination
              by Seller, any of the Purchaser or SC or SCOA, and shall

              Purchaser or SC or SCOA, Seller alone):

              (a) if either of the other parties commits a material
                  breach of its obligations under this Agreement or the
                  License Agreement and does not cure such breach within
                  thirty (30) after receipt of written notice of the
                  breach from the nonbreaching party (which notice shall
                  give reasonable particulars of the breach and of the
                  intention of the party serving the notice to terminate
                  this Agreement unless the breach is cured); or

             (b)  if either of the other parties becomes insolvent, or
                  any voluntary or involuntary petition for bankruptcy
                  or for reorganization is filed by or against either
                  of the other parties, or a receiver is appointed with
                  respect to all or any substantial portion of the
                  assets of either of the other parties, or a
                  liquidation proceeding is commenced by or against
                  either of the other parties; provided that, in the
                  case of any involuntary petition or proceeding filed
                  or commenced against a party, the same is not
                  dismissed within sixty (60) days.

    8.3. Effect of Termination.

              Except as expressly provided otherwise in this Agreement,
              no termination of this Agreement shall release a party
              from any liability or obligation which has theretofore
              accrued and remains to be performed as of the date of such
              termination.

9. ADDITIONAL UNDERTAKINGS

    9.1. Confidentiality of Terms.

              The parties agree that the terms of this Agreement shall
              be treated as Confidential Information of each other
              subject to Article 7; provided, however, that either party
              may, upon notice to the other, make such public
              disclosures regarding this Agreement as in the opinion of
              counsel for such party are required by applicable
              securities laws or regulations.

    9.2. Publicity.

              The parties agree to cooperate in the preparation of a

              relationship established hereby, to be issued promptly
              following execution of this Agreement, but shall otherwise
              make no public announcement regarding the terms of this
              Agreement.

    9.3. Record-Keeping.

              Purchaser shall keep and maintain, and shall cause its
              Affiliates to keep and maintain, sufficient records to
              demonstrate that Purchaser has complied with the obligations
              under this Agreement to purchase from Seller the specified
              percentage of the requirements of Purchaser and its Affiliates
              for Products required for use in the manufactured of Licensed
              Products. Purchaser shall permit Seller's duly authorized
              representative, reasonably acceptable to Purchaser, to examine
              such records at all reasonable business hours to the extent
              and insofar as it is necessary to verify compliance with the
              purchase commitment under this Agreement. Seller shall have
              the right to designate a firm of certified public accountants,
              reasonably acceptable to Purchaser, to audit such records to
              the extent and insofar as it is necessary to verify compliance
              with the purchase commitment under this Agreement. The expense
              of the audit shall be Seller's unless the audit shall
              demonstrate a discrepancy (in Purchaser's favor) greater than
              five percent (5%) between the quantities actually purchased
              hereunder and those which were due to be purchased, in which
              event the audit expenses shall be borne by Purchaser.

    9.4. Export Regulation.

              Sumitomo and Purchaser shall comply in all respects with
              all laws and regulations of the United States government
              or any agency thereof pertaining to exports.

10. ASSIGNMENT

              Neither this Agreement nor any of the rights or
              obligations created herein is assignable by any of the
              parties hereto without the prior written consent of the
              other parties, except that Seller or Purchaser may assign
              this Agreement to any permitted assignee of the License
              Agreement; provided, however, that any such assignment
              shall require the delivery to the other parties of the
              assignee's written agreement to accept such assignment and
              be bound by this Agreement. Any purported assignment in
              violation of this paragraph shall be void. No assignment
              shall relieve the assignor of responsibility for the
              performance of its obligations hereunder.

11. FORCE MAJEURE

              If the performance of this Agreement or any obligations
              under this Agreement is prevented, restricted, or
              interfered with by reason of fire, flood, explosion, or
              other casualty, accident, or act of God; strikes or labor
              disturbances; war, whether declared or not, or other
              violence; sabotage; any law, or order, proclamation,
              regulation, ordinance, demand, or requirement of any
              government agency; or any other event beyond the
              reasonable control of the parties, whether similar or
              dissimilar to the foregoing and whether or not foreseen,
              the affected party, upon giving prompt notice to the other
              parties, shall be excused from such performance to the
              extent of such prevention, restriction or interference.
              The affected party shall use its reasonable efforts to
              avoid or remove such cause of non-performance or to limit
              the impact of the event on such party's performance and
              shall continue performance with the utmost dispatch
              whenever such causes are removed.

              (b) Each party warrants to the other that all approvals of
                  any governmental agency required for such party to

                  Agreement have been obtained prior to the execution
                  hereof.

    12.3. Relationship of the Parties.

              The relationship of the parties under this Agreement is
              intended to be that of independent contractors. Nothing
              herein shall be construed to create any partnership, joint
              venture or agency relationship of any kind. No party has
              any authority under this Agreement to assume or create any
              obligations on behalf of or in the name of any other party
              or to bind any other party to any contract, agreement or
              undertaking with any third party, except that SC and SCOA
              are authorized to act on behalf of the Purchaser as
              contemplated by this Agreement.

    12.4. Dispute Resolution.

              Any disputes or claims arising from this Agreement or its
              breach shall be submitted to and resolved exclusively by
              arbitration conducted in accordance with the Rules of
              Conciliation and Arbitration of the International Chamber
              of Commerce. The arbitration shall be conducted by three
              (3) arbitrators appointed in accordance with such rules.
              The place of arbitration shall be in San Francisco,
              California. An award rendered in the arbitration shall be
              final and binding upon the parties and judgment may be
              entered thereon in any court of competent jurisdiction.
              The arbitrators shall apply the laws specified in this
              Agreement in determining the rights, obligations and
              liabilities of the parties and shall not have the power to
              alter, modify, amend, add to or subtract from any term or
              provision of this Agreement nor to rule upon or grant any
              extension, renewal or continuance of this Agreement, nor
              to award damages or other remedies expressly prohibited by
              this Agreement, nor to grant injunctive relief, including
              interim relief, of any nature, notwithstanding any
              contrary provisions of the Rules of Conciliation and
              Arbitration specified above. If, under applicable law,
              this arbitration provision is not enforceable as to a
              particular claim brought by one party against the other,
              then legal proceedings involving only that claim may be
              instituted solely in the United States District Court of
              the Eastern District of North Carolina or, if such court
              may not exercise jurisdiction, a court of the State of
              North Carolina. For all purposes of this Agreement, all
              parties hereby irrevocably consent to the jurisdiction of
              such court and waive any defense based on improper or
              inconvenient venue or lack of personal jurisdiction.

    12.5. Severability.

              If any provision of this Agreement is found invalid or
              unenforceable, the remaining provisions will be given
              effect as if the invalid or unenforceable provision were
              not a part of this Agreement.

                                Page 10



    12.6. Amendments; Waiver.

              This Agreement may not be amended except in a writing
              signed by the authorized representatives of the parties.
              No waiver of any provision of this Agreement shall be
              effective unless made in writing and signed by the party
              sought to be charged therewith. The failure of either
              party to enforce any provision of this Agreement shall not
              constitute or be construed as a waiver of such provision
              or of the right to enforce it at a later time.

    12.7. No Implied License.

              Nothing in this Agreement shall be construed to convey any
              license under any patent, copyright, trademark or other
              proprietary rights owned or controlled by either party,
              whether relating to the Products sold or any other matter.

    12.8. Enforcement Costs.

              The prevailing party in any arbitration or judicial action
              brought to enforce the provisions of this Agreement shall
              be entitled to recover its costs and expenses, including
              reasonable attorneys' fees, incurred in filing and
              prosecuting or defending such action.

    12.9. Governing Law.

              This Agreement shall be governed by and construed in
              accordance with the laws of the State of North Carolina,
              without regard to conflicts of laws principles.

    12.10. Construction.

              The captions contained in this Agreement are for reference
              only and shall not be used in its construction or
              interpretation. The provisions of this Agreement shall be
              construed and interpreted fairly to both parties without
              regard to which party drafted the same.

    12.11. United Nations Convention.

              The United Nations Convention on Contracts for the
              International Sale of Goods shall not apply to this
              Agreement.

    12.12. Fair Trade Commission Action.

              In the event that the Fair Trade Commission of Japan
              should advise or recommend modification, amendment and/or
              deletion of any terms and conditions of this Agreement
              pursuant to the "Law relating to Prohibition of Private
              Monopoly and Methods of Preserving Fair Trade" of Japan,
              Purchaser and Sumitomo shall immediately inform Seller in
              writing of such advice or recommendation and the parties
              hereto agree to negotiate in good faith to modify, amend,
              and/or delete the terms and conditions concerned in this
              Agreement in accordance with the said advice or
              recommendation. In the event that the parties are unable
              to agree in writing within thirty (30) days after
              Purchaser and Sumitomo inform Seller of the action of the
              Fair Trade Commission, any of the parties hereto may upon
              written notice to the others terminate this Agreement
              without incurring any liability.

  B.       Bare Wafers

           1. Subject to Paragraph 2 below, Purchaser, acting through SC or
              SCOA, will purchase from Seller ********************* % of all
              Bare Wafers required by Purchaser and its Affiliates for the
              manufacture of Licensed Products during the term of this
              Agreement.

           2. If in Purchaser's view Seller's Bare Wafer products become
              noncompetitive with substrates offered by other suppliers
              in respect of price or specifications, or Seller is unable
              to deliver Bare Wafers adequate to meet Purchaser's
              requirement under this Agreement, and in either case
              Purchaser furnishes Seller reasonably adequate evidence of
              such facts, then upon Purchaser's request representatives
              of the parties shall meet and in good faith discuss and
              endeavor to agree upon an appropriate amendment to this
              Agreement or other action to address Purchaser's
              reasonable concerns.

         3.   Without limiting Paragraph 2 above, if during Year 4
              through Year 7 any third party supplier (other than an
              Affiliate of Purchaser) extends a bona fide written offer
              to supply Bare Wafers under terms and conditions at least
              as favorable to Purchaser as those contained in this
              Agreement but at a price lower than the price charged by
              Seller hereunder, Purchaser may purchase the quantity
              offered by such supplier pursuant to the offer, provided
              that (i) such third party substrates meet or exceed the
              applicable Product Specifications under this Agreement,
              (ii) Purchaser gives Seller written notice of the terms of
              the third party offer and Seller does not, within thirty
              (30) days thereafter, agree to supply such quantity under
              the terms and conditions of this Agreement but at the
              price and in accordance with the delivery schedule stated
              in the third party offer, and (iii) the aggregate quantity
              of such substrates (measured by nominal wafer area)
              purchased by Purchaser and its Affiliates from third party
              suppliers during each Agreement Year does not exceed the
              aggregate quantity purchased from Seller during such
              period.

            obligation of the parties to purchase and sell Bare Wafers
            during each Agreement Year is subject to the condition that
            the parties mutually agree as to the price applicable to

            determined the exchange rate between Japanese yen and U.S.
            dollars was a ratio of 110 Japanese yen per one U.S. dollar.
            In the event the exchange rate increases or decreases more
            than twenty percent (20%) from such ratio, the parties shall
            in good faith discuss adjustments to the prices stated in
            this Schedule 1. No such adjustments will be effective
            unless mutually agreed upon writing.
