"BUYER" in this Agreement and the Appendices attached hereto apply equally to
INFiNION, Whiteoak, and ProMOS (except for the different termination provisions

15.1    All disputes arising out of or in connection with this Agreement or
        individual purchase contracts entered hereunder, including any questions
        regarding their existence, validity or termination, but excluding any
        disputes arising from any party's breach or alleged breach of Section 12
        of this Agreement, shall be finally settled under the Rules of
        Arbitration of the International Chamber of Commerce in Paris by three
        arbitrators in accordance with the said Rules.

15.2    Each party shall nominate one arbitrator for confirmation by the
        competent authority under the applicable Rules (Appointing Authority)
        (except that in the case of a dispute between more than one BUYER, on
        one side, and VENDOR on the other, the BUYERS shall nominate one
        arbitrator between them). Both arbitrators shall agree on the third
        arbitrator within 30 days. Should the two arbitrators fail, within the
        above time limit, to reach agreement on the third arbitrator, he shall
        be appointed by the Appointing Authority. If there are two or more
        defendants, any nomination of an arbitrator by or on behalf of such
        defendants must be by joint agreement between them. If such defendants

16.     APPLICABLE LAW

        This Agreement and individual purchase contracts signed between the
        parties hereunder shall be governed by and construed in accordance with
        the law in force in Germany. The application of the United Nations

17.     GENERAL PROVISIONS

17.1    Except for Individual Contracts consistent with Section 1.2, this
        Agreement (together with the Appendices hereto) constitutes the complete
        and exclusive agreement between the parties pertaining to the subject
        matter hereof, and supersedes in their entirety any and all written or
        oral agreements previously existing between the parties with respect to
        such subject matter. Additional agreements and contractual changes must
        be made in writing in order to become effective.

17.2    If individual provisions of this Agreement are or are held to be
        invalid, the validity of the remaining provisions is not affected. In
        this case, the parties or the arbitration panel shall replace the
        invalid provision by a corresponding and appropriate valid provision.

17.3    TO THE MAXIMUM EXTENT PERMITTED BY LAW, EXCEPT FOR VIOLATIONS OF SECTION
        12 OF THIS AGREEMENT AND CASES OF GROSS NEGLIGENCE AND INTENTIONAL ACTS,
        IN NO EVENT WILL ANY PARTY BE LIABLE FOR ANY LOST REVENUES, DATA, OR
        PROFITS, OR SPECIAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES WITH
        RESPECT TO ANY CLAIMS THAT MAY ARISE OUT OF OR IN CONNECTION WITH THIS
        AGREEMENT OR THE TERMINATION THEREOF, EVEN IF SUCH PARTY HAS BEEN
        ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

17.4    VENDOR shall not be responsible for any failure to perform due to
        unforeseen circumstances or to causes beyond VENDOR's reasonable
        control, including but not limited to acts of God, war, riot, embargoes,
        acts of civil or military authorities, fire, floods, accidents, strikes,
        failure to obtain export licenses or shortages of transportation,
        facilities, fuel, energy, labor or materials. In the event of any such
        delay, VENDOR may defer the delivery date of orders for Products for a
        period equal to the time of such delay.

17.5    All parties agree to comply with all applicable international, national,
        state, regional and local laws and regulations in performing their
        duties hereunder and in any of their dealings with respect to the
        technical information and technology disclosed hereunder or direct
        products






                                   page 10/15


        thereof. In addition to such compliance and in particular:

        (i)    BUYER agrees that it will not reexport or release the software or
               technology it receives from VENDOR to any party involved in
               sensitive or unsafeguarded nuclear activities, or activities
               related to chemical or biological weapons or missiles unless
               authorized by the U.S. Export Administration Regulations or a
               license from the U.S. Department of Commerce ("DOC"); and,

        (ii)   Without limiting the generality of Sections 17.5 and 17.5(i)
               immediately above, BUYER agrees that it will not reexport or
               release any technical information or technology it receives from
               VENDOR, including under License Exception TSR, 15 C.F.R. Section
               740.6, to a national of the countries named in Section 17.5(iv)
               below without a license exception or a license from DOC; and,

        (iii)  Without limiting the generality of Sections 17.5 and 17.5(i)
               above, BUYER agrees that it will not export the direct product of
               the technical information or technology it receives from VENDOR,
               including under License Exception TSR, to a country named in
               Section 17.5(iv) below without a license exception or a license
               from DOC if such foreign produced direct product is subject to
               national security controls as identified on the Commerce Control
               List, 15 C.F.R. Supp. No. 1 to Part 774.

        (iv)   Albania, Armenia, Azerbaijan, Belarus, Bulgaria, Cambodia, Cuba,
               China (PRC), Estonia, Georgia, Iran, Iraq, Kazakhstan,
               Kyrgyzstan, Laos, Latvia, Libya, Lithuania, Moldova, Mongolia,
               North Korea, Romania, Russia, Rwanda, Serbia, Sudan, Syria,
               Tajikstan, Turkmenistan, Ukraine, Uzbekistan and Vietnam.

17.6    The sale of Products hereunder by VENDOR does not convey any license to
        BUYER under any patent, copyright, trade secret, trademark or other
        intellectual property right with respect to which VENDOR can grant
        licenses. BUYER agrees not to reverse engineer, disassemble or modify
        ("Reverse Engineer") any Product or any portion thereof without the
        express written permission of VENDOR. The parties acknowledge that under
        EU Directives or applicable local law, persons may have a legal right to
        Reverse Engineer certain interface information under certain limited
        conditions. In the event BUYER believes it has such a legal right to so
        Reverse Engineer any Product, or proposes to perform any Reverse
        Engineering of any Product, BUYER agrees to immediately notify VENDOR in
        writing of such belief, and/or of any proposed Reverse Engineering, and
        BUYER agrees to allow VENDOR a reasonable opportunity after VENDOR's
        receipt and acknowledgment of such notice to provide BUYER with
        sufficient interface information under reasonable terms before it
        performs any Reverse Engineering. Unless or until BUYER so notifies
        VENDOR, BUYER agrees that it has no legal right to Reverse Engineer any
        Product, and expressly waives any such rights it may have in any
        jurisdiction. VENDOR expressly reserves all of its rights with respect
        to any patent, copyright, trade secret, trademark and/or other
        proprietary rights.

17.7    Notwithstanding Section 7.7, subject to Section 17.3 of this Agreement,
        and subject to subsections 17.7.1 through 17.7.4 below, VENDOR will
        defend, indemnify and hold BUYER harmless from any actual loss, damages,
        liabilities and costs (including but not limited to reasonable
        attorney's fees and litigation costs), based upon a third party claim
        that BUYER's use of the Products sold hereunder, or any part thereof,
        constitutes a misappropriation of any






                                   page 11/15


        trade secret, or an infringement of any copyright, issued U.S. patent,
        issued German Patent, issued Taiwanese patent, or issued European patent
        enforceable in Germany. VENDOR's obligations under these Sections 17.7
        through 17.7.4 ("VENDOR's Indemnity") shall arise only if (A) BUYER
        promptly notifies VENDOR when any such claim is made, (B) BUYER is not
        in default of this Agreement, (C) BUYER gives VENDOR sole control of the
        defense and settlement of any such claim, and (D) BUYER furnishes such
        information and assistance as VENDOR may reasonably request in
        connection with the defense, settlement or compromise of such claim.

        17.7.1   Mitigation: In the event BUYER'S use of a Product is, or in
                 VENDOR'S opinion is likely to be, successfully attacked as a
                 result of the type of infringement or misappropriation
                 specified in Section 17.7 above, VENDOR shall , at its sole
                 option and expense, either: (A) procure for BUYER the right to
                 continue using such Products under the terms of this Agreement;
                 or (B) replace or modify such Products so that they are
                 non-infringing and substantially equivalent in function to the
                 enjoined Products; or (C) if options (A) and (B) above cannot
                 be accomplished despite the reasonable efforts of VENDOR, then
                 VENDOR or BUYER may both (i) terminate BUYER's rights and
                 VENDOR's obligations under this Agreement with respect to such
                 Products, and (2) VENDOR shall refund to BUYER the net revenue
                 VENDOR received from BUYER for such Products conditioned upon
                 BUYER's return of the Product to VENDOR.

        17.7.2   Exclusions: VENDOR will have no obligations under Sections 17.7
                 and 17.7.1 above to the extent an infringement or
                 misappropriation arises from: (A) modifications to the Products
                 that were not authorized by VENDOR; (B) Product specifications
                 requested by BUYER; (C) the use of the Products in combination
                 with products not provided by VENDOR, unless (i) VENDOR has
                 offered or promoted the Products to BUYER for use in such
                 combination, and (ii) there is no non-infringing such
                 combination or equivalent combination; or (D) the use of the
                 Products in a process, unless (i) VENDOR has offered or
                 promoted the Products to BUYER for use in such process, and
                 (ii) there is no non-infringing use of the Products in such
                 process or in an equivalent process.

        17.7.3   Sole Remedy: EXCEPT FOR VENDOR'S OBLIGATIONS OF COOPERATION
                 FOUND IN CLAUSES 17.8(i) THROUGH 17.8(iv) BELOW, THE
                 OBLIGATIONS IN SECTIONS 17.7 THROUGH 17.7.2 ABOVE ARE VENDOR'S
                 SOLE AND EXCLUSIVE OBLIGATIONS, AND BUYER'S SOLE AND EXCLUSIVE
                 REMEDIES, WITH RESPECT TO INFRINGEMENT OR MISAPPROPRIATION OF
                 INTELLECTUAL PROPERTY RIGHTS. FOR THE AVOIDANCE OF DOUBT, THERE
                 IS NO WARRANTY, EXPRESSED OR IMPLIED, OF THE Products'
                 NON-INFRINGEMENT, AND, IN THE EVENT OF ANY CLAIMED
                 INFRINGEMENT, VENDOR HAS ONLY THE DUTY TO INDEMNIFY BUYER AS
                 EXPRESSED AND LIMITED IN THIS VENDOR's Indemnity.

        17.7.4   Cumulative Cap on Liability: IN NO CASE SHALL VENDOR'S
                 CUMULATIVE LIABILITY UNDER THIS VENDOR's Indemnity EXCEED AN
                 AMOUNT EQUAL TO THE NET REVENUE VENDOR RECEIVED FROM BUYER FOR
                 THE PRODUCTS COVERED BY VENDOR'S DUTY TO INDEMNIFY BUYER UNDER
                 THIS VENDOR's Indemnity.

17.8    Subject to Section 17.3 of this Agreement, BUYER will defend, indemnify
        and hold VENDOR harmless from any actual loss, damages, liabilities and
        costs (including but not limited to reasonable attorney's fees and
        litigation costs) based upon a third party claim: (A) that any product
        sold by BUYER and processed with Products is defective in design or
        manufacture; (B) subject additionally to Sections 17.8.1 and 17.8.2
        below, and except for infringements for which VENDOR must indemnify
        BUYER under Sections 17.7 through 17.7.4 above, that BUYER's use of the
        Products sold hereunder constitutes a misappropriation of any trade
        secret, or an infringement of any copyright, issued U.S. patent, issued
        German patent, issued Taiwanese patent, or issued European patent
        enforceable in Germany; or (C) that BUYER has breached its obligations
        under Section 17.5 above. BUYER's obligations under these Sections 17.8
        through 17.8.2 ("BUYER's Indemnity") shall arise only if (i) VENDOR
        promptly notifies BUYER when any such claim is made, (ii) VENDOR is not
        in default of this Agreement, (iii) VENDOR gives BUYER sole control of
        the defense and settlement of any such claim, and (iv) VENDOR furnishes
        such information and assistance as BUYER may reasonably request in
        connection with the defense, settlement or compromise of such claim.

        17.8.1   Sole Remedy: EXCEPT FOR BUYER'S OBLIGATIONS OF COOPERATION
                 FOUND IN CLAUSES 17.7(A)-(D) ABOVE, THE OBLIGATIONS IN THIS
                 BUYER's Indemnity ARE BUYER'S SOLE AND EXCLUSIVE OBLIGATIONS,
                 AND VENDORS'S SOLE AND EXCLUSIVE REMEDIES, WITH RESPECT TO
                 INFRINGEMENT OR MISAPPROPRIATION OF INTELLECTUAL PROPERTY
                 RIGHTS. FOR THE AVOIDANCE OF DOUBT, THERE IS NO WARRANTY,
                 EXPRESSED OR IMPLIED, THAT BUYER'S USE OF THE Products WILL NOT
                 INFRINGE A THIRD PARTY'S INTELLECTUAL PROPERTY, AND, IN THE
                 EVENT OF ANY CLAIMED INFRINGEMENT, BUYER HAS ONLY THE DUTY TO
                 INDEMNIFY AS EXPRESSED AND LIMITED IN THIS BUYER's Indemnity.

        17.8.2   Cumulative Cap on Liability: IN NO CASE SHALL BUYER'S
                 CUMULATIVE LIABILITY UNDER THIS BUYER's Indemnity EXCEED AN
                 AMOUNT EQUAL TO THE NET REVENUE VENDOR RECEIVED FROM BUYER FOR
                 THE PRODUCTS COVERED BY BUYER'S DUTY TO INDEMNIFY  VENDOR UNDER
                 THIS BUYER's Indemnity, BUT FOR THE AVOIDANCE OF DOUBT PAYMENTS
                 UNDER THIS BUYER'S INDEMNITY SHALL BE IN ADDITION TO ANY
                 PAYMENTS FOR PRODUCTS.

        VENDOR for any and all taxes or duties that VENDOR may be required to
        pay in connection with this Agreement or its performance.

            voting capital;

      c)    shall be treated by the receiving Party with the same degree of care

            be kept confidential;

      d)    shall remain the property of the disclosing Party.

      obligate either Party to disclose any particular information.

5.    It is understood that no license or right of use under any patent or
      patentable right, copyright, trademark or other proprietary right is
      granted or conveyed by this Agreement. The disclosure of Confidential

      disclosure of any information under this Agreement and agree that no
      warranties of any kind are given with respect to such information as well

      receiving Party shall be excluded.

7.    This Agreement shall be effective as of the date of the last signature as
      written below (the "Effective Date"). It may be terminated with respect to
      further disclosures upon thirty (30) days prior notice in writing. This
      Agreement shall automatically terminate two (2) years from its Effective
      Date. The obligations accruing prior to termination as set forth herein,
      shall, however, survive the termination of this Agreement for a period of
      three (3) years.


8.    All Confidential Information exchanged between the Parties pursuant to
      this Agreement shall upon respective request of the disclosing Party
      either be returned to the disclosing Party or be destroyed by the
      receiving Party after termination of this Agreement. Such request shall be
      notified in writing by the disclosing Party to the receiving Party within
      ninety (90) days after termination of this Agreement. In case of
      destruction, the receiving Party shall confirm in writing such destruction
      to the disclosing Party.

      arbitrators in accordance with the said Rules.

      The seat of arbitration shall be Zurich, Switzerland. The procedural law
      of this place shall apply where the Rules are silent.
