2.0   PRODUCTION CAPACITY AND PURCHASE GUARANTEE:

      2.1 Foundry agrees to provide capacity for and manufacture, and Xicor
      agrees to purchase the quantity of Wafers per month/year specified in
      Appendix B under the terms and conditions set forth herein. It is agreed
      and understood by the parties that the capacity and wafer guarantee
      contained in Appendix B is a minimum requirement only; actual Orders
      placed by Xicor if accepted by Foundry, may exceed these minimum
      requirements. If Xicor fails to purchase the minimum quantity of Wafers
      specified in Appendix B, it will pay the amounts due for such unpurchased
      Wafers (i.e., take or pay).

      2.2 Foundry hereby assumes responsibility for the manufacture of Wafers by
      Device types based on the Designs, and manufactured to the Specifications,
      utilizing the Foundry Process. Foundry will produce Wafers and Devices to
      fill Xicor's accepted orders, as further outlined below.

      2.3 Orders shall be provided by Xicor to Foundry as follows:

            2.3.1 Xicor shall provide Orders to Foundry for Wafers by device
            type. Orders placed by Xicor will be open purchase orders or
            releases for fixed quantities of Wafers by Device type based upon
            the Xicor forecast. Foundry shall accept all Orders within minimum
            guaranteed quantities. Quantities in excess of the guaranteed
            quantities in Appendix B may be accepted at Foundry's sole
            discretion. Foundry shall use reasonable commercial efforts to
            fulfill accepted Orders within the lead times outlined in Appendix
            A.

            2.3.2 On the twentieth (20th) day of each month Xicor will provide
            Foundry a Forecast. The first two months of the Forecast shall be
            firm and supported by released Orders. All subsequent months shall
            be for planning purposes only and,

                                       3
<PAGE>   4

                                                CONFIDENTIAL TREATMENT REQUESTED

            except for the guaranteed quantities specified in Appendix B, in no
            way represent a firm commitment to purchase Wafers by Xicor.

      2.4 Defective Wafers or Devices: When a Wafer manufactured by Foundry
      fails to meet the Yield Specifications, or a Device manufactured by
      Foundry fails to meet the Device Specifications, Xicor and Foundry will
      work together to investigate and determine the root cause of the defect.
      The party which is found to be responsible for causing such failures will,
      at its own cost and responsibility, remove such cause or causes with
      minimum delay. If the root cause of the defect can not be determined, or
      if the parties cannot agree as to which party is responsible for such
      failures, the parties agree to act in good faith to reach an equitable
      resolution acceptable to both parties.

      2.5 Partial Shipments. Xicor will accept deliveries of Wafers made in
      timely installments from Foundry. Any partial shipments will be invoiced
      as made, and payments therefor are subject to the terms of payment noted
      below.

      2.6 Quantity Variance. If the monthly quantity shipped by Foundry of each
      Wafer ordered by Xicor is within +/- 5 percent of the quantity ordered,
      such quantity shall constitute compliance with Xicor's order. Over
      shipments may be accepted at Xicor's discretion, in which case the
      respective quantity of such over shipment may be subtracted from the
      following months' quantity. Any under shipment may, at Xicor's discretion,
      be added to the following months, Order.

      2.7 Modifications. If Xicor determines that modifications to the
      Specifications are required, including modifications to mask tooling,
      process or testing, Foundry agrees to make reasonable modifications within
      a reasonable period of time after notification in writing by Xicor
      provided that the parties agree to adjustment to price and delivery
      schedule if warranted by such modifications, as well as charges for
      retooling costs.

      2.8 Substitutions. Xicor may, at Xicor's sole discretion, add or
      substitute Wafers by Device type as long as the Wafer and Device type
      utilizes a Foundry Process, or similar Foundry Process mutually agreed
      upon by Xicor and Foundry, provided that the agreed upon quantities of
      Wafers by Device type required by Xicor do not exceed those determined
      pursuant to Paragraph 2.3 and 2.6 except with the consent of Foundry. Such
      Wafer and Device types are those which can be manufactured using the same
      process and in accordance with the same qualification plan as Wafers by
      Device type currently manufactured by Foundry under this Agreement.

      2.9 Parametric Failure. If a Device fails to meet the agreed upon
      parametric specifications, Xicor may request Foundry to stop production.
      If Foundry is unable to correct such failures within a reasonable time,
      Xicor may cancel those portions of particular Orders affected by such
      failure at no charge to Xicor. Xicor will notify Foundry in writing of its
      intention to suspend or cancel such Orders and will include any
      substantiating data. Any order cancelled under the terms of this provision
      2.9 shall

                                       4
<PAGE>   5

                                                CONFIDENTIAL TREATMENT REQUESTED

      reduce Xicor's Wafer purchase quantity guarantee in Appendix B by an
      amount equal to the quantity of wafers cancelled.

      2.10 Reports and Reviews: Foundry shall provide Xicor with a weekly
      delivery report. The details and format of such Reports shall be as agreed
      upon by the parties. To enable Xicor to track process control, Foundry
      shall also provide weekly data summarizing the DC parametric measurements
      for Foundry Process. In addition, the parties agree to meet quarterly or
      more frequently if agreed by the parties to discuss and resolve issues
      that may, from time to time, arise and to review Foundry performance.
      Foundry also agrees to provide Xicor with such data and/or reports
      required by Xicor to enable Xicor to maintain their qualification to
      ISO9001 and QS 9000 quality standards.

      2.11 Order Cancellation

            2.11.1 If Xicor cancels an Order that is firm pursuant to Section
            2.3.2, Xicor agrees to pay Foundry an amount equal to the full price
            per wafer for each Wafer cancelled up to the amount of the wafer
            purchase guarantee quantity as per Appendix B. For any Wafers
            cancelled in excess of the wafer purchase guarantee quantity Xicor
            shall pay a cancellation charge per Wafer equal to:

                     (number of mask steps completed)
            R.W.C + [ ------------------------------  x (Wafer price - R.W.C.)]
                       (total number of mask steps)

                          Where R.W.C = raw wafer cost

            Notwithstanding the above, if the parties mutually agree to
            reschedule the Order, no claim shall arise unless the Order as
            rescheduled is canceled. Claims for the canceling of rescheduled
            Orders shall also be governed as set forth above on the date of
            rescheduling.

            2.11.2 If Foundry fails to deliver Wafers and Devices as covered by
            an Order placed hereunder by Xicor, which failure is not corrected
            within sixty (60) days after written notice thereof, Xicor may
            cancel those portions of the Order affected by such failure to
            deliver. If such failure is not corrected within the above sixty-day
            period and is not excused pursuant to Paragraph 19.0, Xicor shall
            have the right to procure substitute goods ("cover") as provided by
            the California Uniform Commercial Code, Section 2712. The foregoing
            shall not affect any other right or remedy available to Xicor. If
            Xicor continues to maintain or place Orders after such default,
            Xicor's actions shall not constitute a waiver nor affect Xicor's
            remedies for such default. Orders cancelled under this provision
            shall reduce the Wafer purchase guarantee quantity in Appendix B by
            an amount equal to the quantity of Wafers cancelled.

3.0   PROCESS TECHNOLOGY:

<PAGE>   6

                                                CONFIDENTIAL TREATMENT REQUESTED

      3.1 Xicor hereby licenses to Foundry the Xicor C3 and C5 process flows,
      process parameters, design rules and other relevant technology identified
      in Appendix C to enable Wafers and Devices to be manufactured by Foundry
      solely for Xicor. Notwithstanding the foregoing, nothing in this Agreement
      shall be construed to limit Foundry's right to use or otherwise exploit
      steps, processes procedures, technologies, or techniques (whether or not
      incorporated into the Foundry Process) that are generic, commonly known or
      used in the industry, or are known to or developed by Foundry independent
      of the processes, materials, or know how received hereunder. In addition,
      Xicor agrees to enter into a Transitional Services Agreement, hereby
      incorporated by reference, whereby Xicor will provide certain services
      relating to the operation of the fabrication facility for a negotiated
      fee.

      3.2 Foundry will run the Foundry Process pursuant to this Agreement, or
      any process which substantially similar to the Foundry Process, solely for
      the purpose of manufacturing Wafers and Devices for Xicor. All Wafers and
      Devices produced by Foundry for Xicor shall be based on the Designs, and
      be manufactured to the Specifications as per Appendices C and D utilizing
      the Foundry Process.

      3.3 Foundry will either (i) provide Xicor with a list of Foundry's
      acceptable mask vendors, in which case Xicor will select and provide one
      of the mask vendors, as mutually agreed, with Device database tapes in GDS
      II format, or (ii) Xicor will provide Foundry with Device database tapes
      in GDS II format and Foundry may procure masks. All such database tapes,
      whether or not marked as confidential as per paragraph 1.7, constitute
      confidential Proprietary Information of the highest level. No such
      database tapes will be provided to any third party mask vendor unless and
      until a written agreement by the mask vendor is executed protecting Xicor
      Proprietary Information from unauthorized disclosure. Foundry will provide
      the mask vendor with mask alignment and test structure database, and
      oversee merging of device and mask alignment databases by the mask vendor.
      Xicor will bear the cost of original mask sets, subject to its advance
      approval of the cost. The cost of subsequent mask layers or sets that are
      required due to abuse or other damage by Foundry will be the
      responsibility of Foundry. The cost of reticle changes required due to
      process or design changes requested by Xicor will be the responsibility of
      Xicor. The cost for reticle changes requested by Foundry for process
      improvement or yield enhancements shall be the responsibility of Foundry.
      Upon termination of this Agreement all mask sets shall be destroyed or
      returned to Xicor. Foundry will provide written certification of such
      return or destruction, and Xicor will provide a written receipt for
      returned mask sets.

      3.4 For new product introduced by Xicor, Xicor may request that Foundry
      provide a mutually agreed quantity of Risk Starts. Foundry will provide
      these Risk Starts to Xicor at the prices determined pursuant to Appendix
      B. Risk Starts shall apply to the Wafer guarantee purchase quantity per
      Appendix B. Xicor will pay for all the Wafers started in the Facility
      against all Risk Start Orders. The criterion of yield specifications will
      not apply to Risk Start Wafers that substantially conform to the C3 and/or
      C5 processes, and

                                       6
<PAGE>   7

                                                CONFIDENTIAL TREATMENT REQUESTED

      the criteria of parametric, electrical, reliability, quality and endurance
      specifications will apply to Risk Start Wafers that substantially conform
      to the C3 and/or C5 processes.

      3.5 Prior to making any Process Change, Foundry agrees to consult with
      Xicor concerning the reasons for and likely effect of the Process Change.
      Foundry will not implement any such Process Change without Xicor's prior
      written approval, which will not be unreasonably withheld or delayed.
      Xicor agrees to qualify the metallurgy change from Molybdenum to Aluminum
      for all C3 and C5 processes as soon as Foundry is able to offer
      qualification wafers for this purpose. Notwithstanding the foregoing, if
      an emergency situation warrants a temporary Process Change, Foundry will
      notify Xicor within 48 hours of identification of the emergency situation.
      In that case Foundry shall provide to Xicor details relating to the
      emergency situation including problem identification, proposed emergency
      Process Change, expected results, expected duration of the Process Change
      and probable ramifications if the emergency Process Change is not
      approved. Xicor shall provide approval/disapproval, via fax, within
      forty-eight (48) hours of receipt of Foundry notification. Unless the
      emergency Process Change is approved by Xicor as a permanent Process
      Change, the process will, within the specified time authorization in the
      emergency process change notification, but in no case greater than one (1)
      week, revert back to the original process which was in effect prior to the
      emergency Process Change. Foundry may extend the time period for such
      reversion to the original process with Xicor's prior approval, which shall
      not be unreasonably withheld or delayed.

4.0   FORECAST AND ORDER COMMITMENT:

      4.1 On the twentieth (20th) day of each calendar month, Xicor shall
      provide to Foundry a Forecast per Paragraph 2.3.2. The Forecast shall be
      used by Xicor to advise Foundry of the Wafer volumes by Device types
      required by Xicor. The first two months of the each Forecast will be
      detailed by week. The remaining months will be detailed by month. Foundry
      will provide Xicor with a response in the form of a confirmation in
      writing to each Forecast by the last working day of each calendar month.
      The response shall contain a commitment schedule for all Wafers and
      Devices for the first two month period.

      4.2 Upon receipt of the commitment schedule, Xicor shall either accept or
      reject the response within three (3) working days. If the committed Wafer
      and Device quantities are acceptable to Xicor, Xicor will provide Foundry
      with Orders to support the agreed upon Wafers and Devices. If the
      committed Wafer and/or Device quantities are unacceptable to Xicor, both
      parties agree to negotiate in good faith until an acceptable resolution is
      reached. The production schedule agreed to by the parties, based on the
      Forecast and Foundry's response, shall be dated, in written form, signed
      by the parties and shall represent a binding commitment for all firm
      Orders. Signature by facsimile is acceptable as proof of execution.

                                                CONFIDENTIAL TREATMENT REQUESTED

      4.3 Each Order shall obligate Xicor to purchase the Wafers and Devices per
      Order. Xicor also agrees to limit the extent of change to each subsequent
      Forecast for future months based on the portion of the previous month's
      Orders that were above the minimum quantity as follows: not more than
      +30%/-15% for the third month, +50%/-30% for the fourth month, +75% / -50%
      for the fifth month and +90% / -50% for the sixth month.

      4.4 Foundry will provide Xicor with actual weekly Wafer by Device
      completions and weekly Wafer by Device shipment reports to be received at
      Xicor no later than 12:00 noon on Wednesday for the previous week's Wafer
      and Device activity.

      4.5 In case Yields drop below the minimum Yield rate as per Appendix B,
      Foundry will use best efforts to expeditiously make up for the missing
      Wafer and/or Device deliveries at Foundry's expense.

5.0   YIELD, RELIABILITY AND QUALITY:

      5.1 Xicor shall have the right to test, monitor or sample any and all
      Wafers and Devices to ensure adherence to the Specifications contained in
      Appendices C and D. Any Wafer or Device failing to meet such
      Specifications within the warranty period set forth in Section 9.1 may be
      returned to Foundry in accordance with the procedure outlined below in
      Paragraph 5.2. In addition, Xicor may stop accepting any or all further
      shipments of affected Wafer and Devices without penalty, provided that
      Xicor and Foundry will meet to develop a mutually agreeable plan for
      determining and eliminating the root cause creating the non-adherence.

      5.2 Xicor shall conduct an analysis of any Wafers and Devices that fail to
      meet the Specifications contained in Appendices C and D. If the results of
      the failure analysis indicate to Xicor that the cause of such failure was
      the responsibility of Foundry, then Xicor shall provide Foundry with
      written notification of the failure and a copy of the failure analysis
      report. Upon completion of Foundry's internal investigation, but no later
      than thirty (30) days after receipt of written notification, if Foundry's
      investigation confirms Xicor's claim, Foundry shall provide Xicor with a
      Return Material Authorization (RMA) and Xicor may return the failed Wafers
      and Devices to Foundry. All costs associated with the return of such
      defective Wafers or Devices, including but not limited to transportation,
      customs, duties or any other such cost, shall be the sole responsibility
      of Foundry. Failure to return or give written notice of rejection of the
      Wafers or Devices within one (1) year after receipt of the Wafers or
      Devices by Xicor shall be considered to be an acceptance of the Wafers or
      Devices by Xicor.

      5.3 The price per Wafer (Appendix B) is based on an agreed upon Yield per
      Device type contained in Appendix B. Should the actual average Yield, as
      reported for all Wafers of the same Device type and delivered exceed the
      target yield by 5% or drop below the target yield by 5% as per Appendix B,
      the price per Wafer will be adjusted upward or downward as per the formula
      in Appendix B.

6.0   PRICES, PAYMENTS AND TAXES:

      6.1 All prices, payments or charges pursuant to this Agreement shall be
      made in US dollars. Agreed upon prices for Wafers are listed in Appendix
      B.

      6.2 All prices are FOB Facility. Title to, and risk of loss of, Wafers and
      Devices shall transfer to Xicor upon release to the carrier. Xicor agrees
      to provide Foundry with an appropriate tax exemption certificate if
      appropriate.

      6.3 Payment terms shall be net thirty (30) days from receipt of a valid
      invoice by Xicor. Foundry shall not send such invoices until Foundry has
      shipped to Xicor the associated Wafers and Devices.

      6.4 Xicor shall have the right to either; (a) offset the cost on any
      future invoice, or (b) obtain a credit from Foundry for any Wafer returned
      to Foundry under Paragraph 5.1 which has previously been invoiced and paid
      by Xicor.

      6.5 Each party shall be solely responsible for any and all taxes, levies
      or any other type of charges imposed upon them by their respective
      sovereign governments.

      6.6 During the course of this Agreement each party shall bear its own
      costs and expenses. Expenses shall mean such expenses as engineering
      materials, fab costs, transportation and hotel expenses associated with
      travel and any other expenses required by the parties to meet their
      obligations under this Agreement.

7.0   ON-SITE INSPECTION: Xicor representatives may visit and tour the areas of
the Facility where the Foundry Process is run, during normal working hours upon
Foundry's approval, not to be unreasonably withheld or delayed, and Foundry may
accompany Xicor on all such visits. Foundry shall keep electrical test records,
process run cards, equipment usage status and Q/A results concerning the Wafers
and Devices for three (3) years after such data is issued, and Xicor
representatives shall be entitled to review such materials during such visits.

8.0   PROPRIETARY INFORMATION:

8.1 Both Foundry and Xicor agree that Proprietary Information of the other will
remain the property of the disclosing party and will be used by them solely for
the purpose of manufacturing Wafers and Devices hereunder. Such Proprietary
Information shall be maintained by each party in confidence and to a degree
equal to or higher than the parties maintain their own proprietary information
of a similar nature. The parties agree that they will not disclose any Propriety
Information to any third party without the prior written permission of the
disclosing party and further agree that such Propriety Information will not be
maintained on any internal computer network that is unsecured and can be
accessed via the internet or any other outside computing system. The parties
agree that all of their respective employees and consultants shall be subject to
non-

<PAGE>   10

                                                CONFIDENTIAL TREATMENT REQUESTED

      disclosure agreements no less protective of Proprietary Information than
      the provisions of this Agreement prior to such employees and consultants
      being allowed access to Proprietary Information.

      8.2 Upon termination or expiration of this Agreement for whatever reason,
      the receiving party must (i) return to the other party the original and
      all copies of any Proprietary Information of the disclosing party, or (ii)
      destroy the originals and all copies of any Proprietary Information and
      provide certification of such destruction to the disclosing party, and
      (iii) at the disclosing party's request, have one of its officers certify
      in writing that it will not make any further disclosure or use of such
      Proprietary Information and specifically will not manufacture or have
      manufactured for it any product incorporating such Proprietary
      Information.

      8.3 These confidentiality provisions as to any item of Proprietary
      Information shall survive the termination of this Agreement for a period
      of five (5) years from the date of termination of this Agreement.

      8.4 Notwithstanding Section 10.1, If Foundry and Xicor jointly develop any
      process modifications, each party grants to the other party the
      non-exclusive right to use such process modifications. The parties further
      agree that if such jointly developed process modifications are patentable,
      and both parties wish to pursue such patent, the parties shall equally
      share the cost of filing such patent and the parties shall become
      co-owners of such patents. If only one party wishes to pursue such patent,
      then the pursuing party shall bear all costs and the non-pursuing party
      shall be granted a non-exclusive, royalty free license for such patent.

9.0   WARRANTY OF FOUNDRY AND ACCEPTANCE:

      9.1   Foundry warrants that Wafers and Devices delivered hereunder will
            meet the mutually agreed Specifications and shall be free from
            material defects in material and workmanship under normal use and
            service for a period of one year from the date of receipt from
            Foundry's facility. If, during such one year period (i) Foundry is
            notified with reasonable promptness in writing upon discovery of any
            defect in the Wafers and Devices, including a reasonably detailed
            description of such defect; (ii) and when physically available such
            Wafers and Devices are returned to Foundry's facility,
            transportation prepaid; and (iii) Foundry's reasonable examination
            of such Wafers and Devices discloses that such Wafers and Devices
            are defective and such defects are not caused by accident, abuse,
            misuse, neglect, improper installation, repair or alteration not
            authorized by Xicor, improper testing or use contrary to any
            reasonable instructions issued by Xicor, then within a reasonable
            time Foundry shall, as mutually agreed, either repair, replace, or
            credit Xicor for such Wafers and Devices. Foundry shall reimburse
            Xicor for the return transportation charges paid by Xicor for such
            Wafers and Devices. Foundry shall return any Wafers and Devices
            repaired or replaced under this warranty to Xicor transportation
            prepaid. If replacement of any Wafer and/or

                                       10
<PAGE>   11

                                                CONFIDENTIAL TREATMENT REQUESTED

            Device is not practical, then Foundry shall issue a credit to Xicor
            for the price paid by Xicor for the defective Wafers. The
            performance of this warranty does not extend the warranty period
            applicable to the Wafers and Devices originally delivered.

      9.2   FOUNDRY MAKES, AND XICOR RECEIVES, NO REPRESENTATIONS, WARRANTIES OR
            CONDITIONS (EXPRESSED, IMPLIED, STATUTORY OR OTHERWISE), OTHER THAN
            AS EXPRESSLY SET FORTH IN THIS SECTION 9, INCLUDING, WITHOUT
            LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
            FOR ANY PARTICULAR PURPOSE AND THEIR EQUIVALENTS UNDER THE LAWS OF
            ANY JURISDICTION.

      9.3   Foundry shall promptly advise Xicor whenever Foundry has reason to
            believe that Wafer and/or Devices may not conform to the applicable
            Specifications.

10.0  NON-COMPETITION / REPRESENTATIONS AND WARRANTIES OF XICOR:

      10.1 Foundry specifically agrees that it will not at any time use for its
      own purposes, or any other purpose other than those specified by this
      Agreement, any Xicor Proprietary Information unless specifically evidenced
      by a separate technology licensing agreement properly executed by Xicor.
      Xicor specifically agrees that it will not at any time use for its own
      purposes, or any other purpose other than those specified by this
      Agreement, any Proprietary Information of Foundry unless specifically
      evidenced by a separate technology licensing agreement properly executed
      by Foundry.

      10.2 Xicor warrants that the Foundry Process, Wafers, Devices and Designs
      or any parts thereof do not infringe on any United States or other country
      patent, copyright, trade secret, trademark or other intellectual property
      right.

11.0  INDEMNIFICATION AND LIMITATION OF LIABILITY:

      11.1 Xicor agrees, at its own expense, to defend or at its option to
      settle, any claim, suit or proceeding brought against Foundry on the issue
      of infringement of any United States or other country patent, copyright,
      trade secret, trademark, or other intellectual property right with respect
      to the Foundry Process, Wafers, Devices or Designs or any parts thereof
      subject to the limitations hereinafter set forth. Xicor shall have sole
      control of any such action or settlement negotiations, provided that Xicor
      shall not, without the consent of Foundry, enter into any settlement or
      agree to any disposition that imposes an obligation on Foundry that is not
      wholly discharged or dischargeable by Xicor, or imposes any conditions or
      obligations on Foundry other than the payment of monies that are readily
      measurable for purposes of determining the monetary indemnification or
      reimbursement obligations of Xicor. Xicor agrees to pay, subject to the
      limitations hereinafter set forth, any final judgment or settlement
      entered against Foundry or its

                                       11

                                                CONFIDENTIAL TREATMENT REQUESTED

      customer (as well as attorneys' fees and other expenses) on such issues in
      any such suit or proceeding defended by Xicor. Foundry agrees that Xicor
      shall be relieved of the foregoing obligations unless Foundry notifies
      Xicor promptly in writing of such claim, suit or proceeding and gives
      Xicor authority to proceed as contemplated herein, and, at Xicor's expense
      (except for the value of the time of Foundry's employees), gives Xicor all
      reasonable information and assistance to settle and/or defend any such
      claim, suit or proceeding. Xicor shall not be liable for any costs or
      expenses incurred by Foundry without Xicor's prior written authorization.
      Foundry shall at all times have the option to participate in any matter or
      litigation through counsel of its own selection and at its own expense.

      11.2 The foregoing provisions of this Article state the entire liability
      and obligations of the indemnifying party and the exclusive remedy of the
      indemnified party, with respect to a breach of representations and
      warranties in Section 10 and any alleged infringement of patent,
      copyright, trade secret, trademark or other intellectual property right by
      the Wafer, process, or any part thereof.

      11.3 IN NO EVENT WILL EITHER PARTY BE LIABLE FOR ANY CONSEQUENTIAL,
      INDIRECT, INCIDENTAL, SPECIAL OR PUNITIVE DAMAGES IN ANY MANNER ARISING
      OUT OF THIS AGREEMENT, EVEN IF A PARTY HAS BEEN ADVISED IN ADVANCE OF THE
      POSSIBILITY OF SUCH DAMAGES.

12.0  TERM:

      12.1 This Agreement shall come into force on the Effective Date and shall
      remain in force for a period of five (5) years from the Effective Date
      unless terminated in accordance with Paragraph 16 below.

      12.2 This Agreement may be renewed for an additional period under terms
      and conditions agreeable to both parties hereof.

13.0  EXPORT CONTROLS: Foundry will not export, re-export, transship, or
transmit, directly or indirectly, (collectively "Export"), any data, designs,
programs, hardware, or technical information of any kind acquired hereunder, or
any direct product thereof to any country to which such Export is limited, or
prohibited by the United States Government or any law, regulation, agency or
executive order thereof, including without limitation, the Export Administration
Regulations of the US Department of Commerce. This Agreement is subject to
compliance with all applicable export and import laws and regulations and the
parties agree to cooperate in complying therewith. Foundry agrees to indemnify
Xicor for any fees, fines or penalties imposed on Xicor by the United States
Government as a result of Foundry's breach or violation of this provision. If
requested, Xicor shall provide Foundry with information regarding the Export
Administration Regulations of the U.S. Department of Commerce.

14.0 PUBLICITY: Foundry acknowledges that Xicor will publicly announce this
Agreement and its contents as a result of obligations imposed under the
regulations of the United States Securities and Exchange Commission regarding
financial and other disclosures. Xicor will use commercially reasonable efforts
to seek confidential treatment of pricing terms of the Agreement, although it
can not assure Foundry that it will succeed in its efforts. No other public
announcements concerning this Agreement will be made by either party without the
prior written consent of the other which will not be unreasonably withheld.

15.0 NON-DISCLOSURE OF TERMS AND CONDITIONS: Neither party shall, without first
obtaining the written consent of the other party, disclose the terms, conditions
or subject matter of this Agreement, unless, in the good faith judgment of the
disclosing party, such disclosure is: (i) in response to a valid court order, in
which case the party making the disclosure pursuant to the valid court order
shall first have informed the other party and made reasonable efforts to obtain
a protective order requiring that the information or document so disclosed be
used only for the purpose for which the order was issued, or (ii) as may be
otherwise required by law, rules or government regulations or other governmental
body of the United States or any political subdivisions thereof; provided that
the disclosing party requests confidential treatment of sensitive information by
the appropriate governmental agency, or (iii) necessary to establish the parties
rights under this Agreement.

16.0  TERMINATION:

      16.1 Either party may terminate this Agreement for a material default of
      any of the terms and conditions of this Agreement by the other party,

      provided with sixty (60) days after receipt of the notice to correct the
      defaulting condition.

      16.2 Either party may terminate this Agreement without cause upon
      providing the other party with six (6) months written notice thereof, but
      neither party may terminate this agreement without cause prior to October

      to terminate this Agreement by giving written notice of termination to the
      other party at any time on or after the filing by the other party of a
      petition in bankruptcy or insolvency.

15, 17, 23, 24, 25, 26 and 27 shall survive the termination or expiration of
this Agreement.

18.0. SEVERABILITY: If any provision of this Agreement, or the application
hereof to any situation or circumstance, shall be invalid or unenforceable, the
remainder of this Agreement or the application of such provision to situations
or circumstances other than those as to which it is invalid or unenforceable,
shall be intact; and each remaining provision of this Agreement shall be valid
and enforceable to the fullest extent permitted by applicable law. In the event
of such partial invalidity the parties shall seek in good faith to agree on
replacing any such legally invalid provisions with provisions, which, in effect,
will, from an economic viewpoint, most nearly and fairly approach the effect of
the invalid provision.

B2:   WAFER PRICE ADJUSTMENTS FOR SORT YIELD:

      TIMING: Once every 6 months. These calculations are inspired by two
              things:

1.    Yield improvements made by Foundry are to be rewarded with better wafer
      price,

2.    Yield improvements made are to be shared by the two companies.

      CALCULATION: Every 6 months, Xicor will calculate the actual yield
      percentage and compares to the target as set forth in Table 1.

      Table 1: Starting "target" wafer sort yield percentages for Xicor products
      to be used for price calculations.

-     If the average wafer yield percentage of the total number of wafers
      shipped in the previous 6 months is within + or - 5% of target, the wafer
      price for the next 6 months stays the same.

-     If the actual wafer yield percentage is different by greater than + or -
      5% of target, the difference will be shared equally by Xicor and Foundry
      and a new wafer price will be established for the next 6 month period
      based on the following example:
