12.1     ITEX will develop and process prototypes in accordance with the
         milestones set out in the IMPLEMENTATION SCHEDULE attached hereto as
         Annex 2. ITEX will manufacture engineering samples of the PRODUCT. Upon
         request of ALCATEL, ITEX will enter into a supply agreement with

         standards.

12.3     ITEX will utilize its sales and marketing networks world-wide to
         promote the sales of the PRODUCT. In order to allow ITEX to familiarize
         its sales and marketing networks with the PRODUCT and to promote the
         PRODUCT before ITEX's own manufacturing thereof may be started, ALCATEL
         will supply the PRODUCT to ITEX under reasonable terms and conditions
         to be mutually agreed upon.

12.4     ITEX will use its [*] to produce the PRODUCT, and/or parts thereof in
         sufficient volume to meet its customers and ALCATEL's demand therefor.

                  manufacture, distribution, sale or other supply of any
                  manufactured goods which by reason of their properties and
                  performance are commercially competitive with the PRODUCT. For
                  the avoidance of doubt, this section 12.5(iii) shall not
                  restrict ITEX in the exercise of the rights granted to ITEX in
                  Section 2.1.3 hereof in connection with the SAM.

                  reasonably foreseeable purpose; or
         (iv)     is or may be injurious to the property of any person referred
                  to in Section 12.6.

         ITEX represents that it shall at all times during the TERM of this
         AGREEMENT maintain in force such policies of insurance with a

         liabilities, claims and costs arising from any of the causes, events or
         circumstances referred to herein above. ITEX shall provide copy to
         ALCATEL of any and all relevant insurance policies, and will notify
         ALCATEL of any and all expiry, termination, renewal or change occurring
         in its relevant insurance portfolio.

12.7     A Steering Committee with [*] from each Party will be established and
         will meet as the Parties deem required, in order to review:
         (i)      the evolution of market requirements;
         (ii)     the possible corrective actions to be proposed by ITEX to
                  ALCATEL for the improvement of the PRODUCT in terms of
                  features, performances, manufacturability and costs;
         (iii)    all issues relating to new market penetration for the PRODUCT,
                  as well as other issues of common interest.

12.8     Although ITEX is under no obligation to register shares or engage in an
         IPO, and ITEX makes no promises that it will do so, in the event that
         ITEX successfully receives all requisite approval for a public offering
         of its shares, ITEX will exert [*] to convince its underwriters to
         offer ALCATEL the opportunity to purchase in the offering [*] of the
         outstanding shares of ITEX (calculated on a post offering basis).

                  a breach of any obligation contained in Section 7.2 or Clause
                  11 will be considered a material breach of a material
                  obligation; or
         (iii)    if the other Party enters into liquidation whether compulsory
                  or voluntary (other than for the purposes of amalgamation or
                  reconstruction approved in writing by the former Party) or has
                  a receiver or administrative receiver or administrator or
                  similar official appointed over all or any of its assets and
                  is not discharged within a period of [*] days; or

         (iv)     if the other Party is declared insolvent or makes any general
                  composition with its creditors; or
         (v)      if the other Party ceases or threatens to cease to carry on
                  the whole or any material part of its business and any such
                  cessation, in the opinion of the former Party would be likely
                  to affect adversely the other party's ability to observe and
                  perform properly and punctually all or any of its obligations
                  under or pursuant to this AGREEMENT;

15.3     Notwithstanding the provisions of Section 15.1 and forthwith upon the
         occurrence of any of the following events, ALCATEL may without
         prejudice to any other right or remedy by written notice to ITEX
         terminate this AGREEMENT with immediate effect if:
         (i)      ITEX does not commence to make sales of the PRODUCT in
                  reasonably commercial quantities within [*] months following
                  the EFFECTIVE DATE; or
         (ii)     control (as defined in SUBSIDIARIES) or the power to take
                  control of ITEX is acquired by any person or group of
                  associates not having control of ITEX at the date of this
                  AGREEMENT unless such event occurs with the prior consent in
                  writing of ALCATEL.
         (iii)    ITEX challenges the validity or proprietorship of the
                  registered INTELLECTUAL PROPERTY RIGHTS or does any act or
                  thing which might impair the rights of ALCATEL in the
                  TECHNOLOGY or represents that it has any rights in the
                  TECHNOLOGY other than under and by virtue of this AGREEMENT.
                  This section does not cover any lawful applications (or
                  acquisitions) by ITEX of (or for) patent rights either prior
                  to and/or during the term of this AGREEMENT.

15.4     Termination of this AGREEMENT shall not release either of the Parties
         from any other liability which at the time of termination has already
         accrued to the other Party, nor affect in any way the survival of any
         other right, duty or obligation of the Parties which is expressly
         stated elsewhere in this AGREEMENT to survive such termination.

15.5     ITEX undertakes with ALCATEL that upon the expiration of the TERM or
         sooner determination of this AGREEMENT, ITEX shall at its own cost
         promptly return to ALCATEL or otherwise dispose of as ALCATEL may
         instruct all TECHNICAL DOCUMENTATION and all other documentation and
         papers supplied to ITEX by ALCATEL and all copies thereof and notes and
         extracts taken therefrom by ITEX and shall supply to ALCATEL within [*]
         days after the expiration of the TERM or sooner determination of this
         AGREEMENT a certificate signed by [*] directors of ITEX as to the
         destruction of all such materials.

ARTICLE 16 - SOLICITING EMPLOYEES

ITEX undertakes with ALCATEL that during the TERM it will not directly or
indirectly solicit or endeavor to entice away, offer employment to or employ, or
engage as an independent contractor (other than staff who have applied for
genuine vacancies advertised by the other) any person who is employed or engaged
by ALCATEL, who is employed or engaged or was employed by or engaged by ALCATEL
during the preceding [*] months.

ARTICLE 17 - FORCE MAJEURE

17.1     Force Majeure shall mean all events which are beyond the control of the
         Parties to this AGREEMENT, and which are unforeseen, unavoidable or
         insurmountable, and which arise after the EFFECTIVE DATE and which
         prevent total or partial performance by either Party. Such events shall
         include hostilities (whether war be declared or not), embargo or
         blockade, failure or delay in transportation, labor disputes involving
         complete or partial stoppages, riot, acts done in compliance with
         governmental request, earthquakes, explosion, typhoons, flood, fire,
         war or any other instances which cannot be foreseen, prevented or
         controlled, including instances which are accepted as force majeure in
         general international commercial practice.

17.2     If an event of Force Majeure occurs, a Party's contractual obligations
         affected by such an event under this AGREEMENT shall be suspended
         during the period of delay caused by the Force Majeure and shall be
         automatically extended, without penalty, for a period at least equal to
         such suspension.

17.3     The Party claiming Force Majeure shall promptly inform the other Party
         in writing and shall furnish within thirty (30) days thereafter
         sufficient proof of the occurrence and duration of such Force Majeure.
         The Party claiming Force Majeure shall also use all reasonable
         endeavors to terminate the Force Majeure.

17.4     In the event of Force Majeure, the Parties shall immediately consult
         with each other in order to find an equitable solution and shall use
         all reasonable endeavors to minimize the consequences of such Force
         Majeure.

17.5     This AGREEMENT may be terminated by the Party who is being prejudiced
         by the non-performance of the Party claiming the Force Majeure excuse,
         by giving written notice of termination to such non-performing Party,
         at any time after the Force Majeure event has continued to be in effect
         for more than six (6) months from the date on which the excused
         performance was originally due hereunder. The non-performing Party
         shall however be obligated to exercise its best reasonable efforts to
         overcome the effects of Force Majeure during the pendency thereof by
         means of substitute performance or any other method which will mitigate
         the loss or damage that could result to the other Party from such
         non-performance, provided such substitute performance does not result
         in financial hardship to the Party involved therein.

ARTICLE 18- MANUFACTURE DISCONTINUANCE

In the event of ITEX's decision to discontinue manufacture of the PRODUCT, ITEX
shall give ALCATEL [*] months prior notice and accept orders from ALCATEL
sufficient to cover its needs for a life time buy to be scheduled for delivery
up to [*] months after the above mentioned [*] months period. Should needs
specified by ALCATEL within the framework of this Article 18 be incompatible
with such reasonable availability of manufacturing capacity for the PRODUCT,
ITEX shall immediately give written notification thereof to ALCATEL, and upon
such notification, the PARTIES shall, at the initiative of either Party, meet in
order to agree in good faith on such arrangements as may be required by their
respective commercial interests.

ARTICLE 19 - GOVERNING LAW AND SETTLEMENT OF
DISPUTES

19.1     This Agreement shall be construed in accordance with and governed by
         the Law of Belgium (without regard to its conflicts of law rules),
         provided however, that if any provision of Belgian law purports to
         change any material term hereunder, to impose any material obligation,
         duty, warranty or burden on a party beyond, contrary to, and/or in
         addition to those expressly stated herein, then all aspects of this
         Agreement so affected shall not be subject to such law, and instead, to
         the extent necessary or appropriate to give effect to and/or to
         implement the express terms of this Agreement, this Agreement shall be
         governed solely and exclusively by the law of the State of California.

19.2     All disputes arising out of and/or in connection with this Agreement
         shall be finally settled by arbitration in accordance with the Rules of
         the London Court of International Arbitration. The arbitration will be
         held in London, England, and will be before a single arbitrator
         designated in conformity with the said Rules. The arbitrator (i) shall
         be neutral and without business affiliation with either party; (ii)
         shall not be a citizen or resident of the United States nor Belgium;
         (iii) shall have reasonable expertise in business and financial aspects
         of the computer and electronics industry; and (iv) shall make detailed
         and complete findings of fact and conclusions of law in writing. The
         arbitration proceedings shall be held entirely in the English language
         and shall be subject to such conditions and precautions as may be
         appropriate to protect the confidential information of each party in a
         manner consistent with and at least as secure as the provisions of this
         Agreement. In interpreting this Agreement, the arbitrator shall take
         into account usage's in the computer electronics and software trade,
         particularly with a view to interpreting the confidentiality and trade
         secret provisions of this contract in strict terms.

19.3     Judgment upon the arbitration award rendered may be entered in any
         Court having jurisdiction thereof, of having jurisdiction over either
         of the parties or their assets, or application may be made to such
         Court for a juridical acceptance of the award and an order of
         enforcement, as the case may be.

19.4     Nothing in this Agreement shall be deemed as preventing either party
         from seeking injunctive relief (or any other provisional remedy) from
         any court having jurisdiction over the parties and the subject matter
         of the dispute as necessary to protect either party's name, proprietary
         and/or intellectual property information, trade secrets, know-how or
         any other proprietary rights

ARTICLE 20 - MISCELLANEOUS PROVISIONS

20.1     If any Party fails to give notice or enforce any right under this
         AGREEMENT, such failure shall not constitute a waiver of the right,
         unless such waiver is contained in written notice signed by the duly
         authorized representatives of the waiving Party. If a Party waives its
         right in writing, such waiver shall not constitute a waiver of any
         other right or of a subsequent violation of the same right.

                                     28/30

20.2     ITEX shall be entitled at any time to subcontract the performance of
         any of its obligations under this AGREEMENT to its SUBSIDIARIES,
         provided that such SUBSIDIARIES will comply with all applicable
         obligations undertaken by ITEX herein and that ITEX will remain liable
         for the performance of such subcontracted obligations towards ALCATEL.
         ITEX may not nor may purport to assign, transfer, charge or part with
         all or any of its rights and/or obligations under this AGREEMENT or
         sub-contract the performance of any of its obligations under this
         AGREEMENT without the prior written consent of ALCATEL. Such consent,
         however, shall not be necessary for activities and services normally
         sub-contracted by ITEX in connection with the design, manufacturing or
         testing of its products (or the processes for making the same),
         including but not limited to circuit design, simulation, verification,
         mask making, testing, and similarly related activities, to the extent
         that such activities do not require such subcontractor to be given
         access to the TECHNOLOGY or any part thereof.

20.3     This AGREEMENT is made for the benefit of ITEX and ALCATEL and their
         respective lawful successors and assignees and is legally binding on
         them. This AGREEMENT may not be changed orally, but only by a written
         instrument signed by ITEX and ALCATEL.

20.4     The invalidity of any provision of this AGREEMENT shall not affect the
         validity of any other provision of this AGREEMENT.

20.5     This AGREEMENT and the Annexes hereto attached to this AGREEMENT
         constitute the entire agreement between ITEX and ALCATEL with respect
         to the subject matter of this AGREEMENT and supersede all prior
         discussions, negotiations and agreements, either oral or written,
         between them. In the event of any conflict between the terms and
         provisions of this AGREEMENT and its Annexes, the terms and provisions
         of this AGREEMENT shall prevail.

20.6     ALCATEL's liability Under this AGREEMENT and its implementation are
         fully described in the present AGREEMENT and are limited to the extent
         as mentioned in this AGREEMENT.
         REGARDLESS WHETHER ANY REMEDY SET FORTH HEREIN FAILS OF ITS
         ESSENTIAL PURPOSE OR OTHERWISE, IN NO EVENT SHALL ALCATEL BE LIABLE
         FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES OF
         ANY KIND, EVEN IF ADVISED IN ADVANCE OF THE POSSIBILITY OF SUCH
         DAMAGES. ALCATEL'S ENTIRE CUMULATIVE LIABILITY UNDER THIS
         AGREEMENT, FROM ALL CAUSES OF ACTION OF ANY TYPE, SHALL BE LIMITED
         TO THE AMOUNTS RECEIVED FROM ITEX HEREUNDER WITH A MAXIMUM OF [*]
         REGARDLESS WHETHER ANY REMEDY SET FORTH HEREIN FAILS OF ITS
         ESSENTIAL PURPOSE OR OTHERWISE, AND SUBJECT TO SUCH
         INDEMNIFICATIONS AS MAY BE DUE IN ACCORDANCE WITH SECTION 12.6
         HEREOF, WHICH IS SPECIFICALLY EXCLUDED FROM THE PRESENT LIMITATION,
         IN NO EVENT SHALL ITEX BE LIABLE RO ANY INDIRECT, INCIDENTAL,
         CONSEQUENTIAL OR SPECIAL DAMAGES OF ANY KIND, EVEN IF ADVISED IN
         ADVANCE OF THE POSSIBILITY OF SUCH DAMAGES.

                 CAREFULLY READ ALL OF THE TERMS AND CONDITIONS
                       OF THIS SOFTWARE LICENSE AGREEMENT
           BEFORE YOU USE THE SOFTWARE [add name and release number].

THIS SOFTWARE LICENSE AGREEMENT (THIS "AGREEMENT") IS A LEGALLY BINDING
AGREEMENT BETWEEN THE PURCHASER OF THE SOFTWARE (THE "PURCHASER") AND ALCATEL
BELL N.V. ("ALCATEL"). BY USING, INSTALLING OR CLICKING THE ACCEPTANCE BUTTON OF
THE SOFTWARE (AS UPDATED BY ALCATEL FROM TIME TO TIME, THE "SOFTWARE") THE

AGREEMENT.

1.  GRANT OF LICENSE.  The Software and all accompanying documentation (the
"Documentation) are licensed to the Purchaser under the terms and conditions set
forth in this Agreement. Subject to such terms and conditions, Alcatel hereby
grants to the Purchaser a non-exclusive, nontransferable right to use the
Software and the Documentation. The Purchaser may use the Software on a single
computer located in the country where the Purchaser purchased the Software or
any other country to which the Software is legally exported. The Software is in
use by a single computer when the Software is installed into the permanent or
temporary memory of that computer. The Software is in use by multiple computers
when (a) the Software is installed on a single computer and at least one copy of
the Software is installed on at least one other computer or (b) the Software is
installed on the storage device of a network server for the purpose of
distribution to at least two other computers. When the Software is in use by
multiple computers, the Purchaser must purchase a separate license for the
Software for each of those computers unless the Purchaser has purchased a
license allowing explicitly use for multiple computers in which case the
Purchaser may use the Software on the agreed upon number of computers.

2.  LIMITATIONS ON USE.  The Purchaser will not modify or translate the Software
or the Documentation without the prior written consent of Alcatel. The Purchaser
will not reverse engineer, decompile, disassemble or otherwise attempt to
recreate the source code of the Software. The Purchaser will not separate from
the Software any of the component parts of the Software.

3.  LIMITATIONS ON DUPLICATION.  The Purchaser will not make any copies of the
Software or the Documentation; provided, however, that the Purchaser may make
one complete copy of the Software or the Documentation solely for backup
purposes if such copy of the Software or Documentation contains the notation
"Copyright Alcatel". The Purchaser will not print any on-line or electronic
documentation other than solely for servicing, operating or training purposes.

<PAGE>

4.  LIMITATIONS ON TRANSFER.  The Purchaser will not sell, rent, lease or
otherwise transfer any or all of the Software, the Documentation or any copies
thereof, without the prior written consent of Alcatel. The Purchaser will not
sublicense, assign, delegate, rent, lease or otherwise transfer any or all of
its rights under this Agreement.

5.  OWNERSHIP AND COPYRIGHT.  The Purchaser has not acquired, by virtue of this
Agreement, any right of ownership in or to the Software, the Documentation or
any related patent, copyright, trademark or other intellectual property right.
By virtue of this Agreement, the Purchaser has acquired a right of ownership
solely in and to the physical media on which the Software and the Documentation
are recorded or fixed. Alcatel, its licensors and their respective licensors
retain all right, title and interest in and to the Software, the Documentation
and any and all copies thereof, except for the rights expressly granted to the
Purchaser pursuant to this Agreement and as may be granted by Alcatel from time

interest of Alcatel's licensors and their respective licensors may be, protected
by applicable copyright laws and international treaties.

6.  TERM AND TERMINATION.  The term of this Agreement commences upon the
first use by the Purchaser of the Software and expires upon the termination
of this Agreement. If the Purchaser fails to comply with any of the terms and
conditions set forth in this Agreement, then (a) this Agreement will
automatically terminate, (b) notwithstanding such termination, the Purchaser
will (i) destroy or permanently erase the Software and any and all copies
thereof and (ii) destroy the Documentation and any and all copies thereof,
and (c) Alcatel may exercise any or all remedies available to it under
applicable laws. In addition, the Purchaser may terminate this Agreement at
any time by (a) destroying or permanently erasing the Software and any and
all copies thereof and (b) destroying the Documentation and any and all
copies thereof.

7.  NO WARRANTIES.  THE SOFTWARE IS MADE AVAILABLE TO THE PURCHASER ON AN "AS
IS" BASIS WITHOUT ANY EXPRESS, IMPLIED OR STATUTORY WARRANTIES WHATSOEVER,
INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE.

Some jurisdictions may not permit the exclusion of implied warranties; so the
above exclusion may not apply to the Purchaser. The Purchaser may have other
rights that vary from jurisdiction to jurisdiction.

Alcatel may from time to time, in its sole discretion, make available to the
Purchaser, with or without charge, updates to the Software or the
Documentation. No such action will create any warranty obligation on the part of
Alcatel.

8.  LIMITATION OF REMEDIES.  IN NO EVENT WILL ALCATEL, ITS LICENSORS OR THEIR
RESPECTIVE LICENSORS BE LIABLE FOR ANY DAMAGES OR OTHER RELIEF WHATSOEVER
ARISING OUT OF PURCHASER'S USE OR INABILITY TO USE THE SOFTWARE OR THE
DOCUMENTATION, INCLUDING WITHOUT LIMITATION LOST PROFITS, LOST BUSINESS OR LOST
OPPORTUNITY OR ANY SPECIAL, INCIDENTAL OR CONSEQUENTIAL OR EXEMPLARY DAMAGES OR
LEGAL FEES ARISING OUT OF SUCH USE OR INABILITY TO USE THE SOFTWARE, EVEN IF
ALCATEL, ITS LICENSORS OR THEIR RESPECTIVE LICENSORS HAVE BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

<PAGE>

Some jurisdictions may not permit the exclusion or limitation of incidental
or consequential damages; so the above exclusion or limitation may not apply
to the Purchaser.

9.  GOVERNING LAW.  This Agreement will be governed by and construed in
accordance with the laws of Belgium, without giving effect to the conflicts
of laws principles thereof.

10.  OTHER TERMS.  Additional or different terms and conditions may be

         affiliation with either party; (ii) shall not be a citizen or resident
         of the United States nor Belgium; (iii) shall have reasonable expertise
         in business and financial aspects of the computer and electronics

         held entirely in the English language and shall be subject to such
         conditions and precautions as may be appropriate to protect the
         confidential information of each party in a manner consistent with and
         at least as secure as the provisions of this Non Disclosure Agreement.
         In interpreting this Agreement, the arbitrator shall take into account
         usages in the computer electronics and software trade, particularly
         with a view to interpreting the confidentiality and trade secret
         provisions of this Non Disclosure Agreement in strict terms.
         Arbitration will be final and binding upon the Parties.

4.3      Judgment upon the arbitration award rendered may be entered in any
         Court having jurisdiction thereof, of having jurisdiction over either
         of the parties or their assets, or application may be made to such
         Court for a juridical acceptance of the award and an order of
         enforcement, as the case may be.

4.4      Nothing in this Agreement shall be deemed as preventing either party
         from seeking injunctive relief (or any other provisional remedy) from
         any court having jurisdiction over the parties and the subject matter
         of the dispute as necessary to protect either party's name, proprietary
         and/or intellectual property information, trade secrets, know-how or
         any other proprietary rights.

                  only upon such terms as ensure protection for confidentiality
                  at least as stringent as provided herein), and not to use it
                  for any purpose other than such verification.

     3.5.3    RECORD KEEPING. UMC SPINOFF shall retain such books and records as
              are reasonably necessary for verifying the calculation of

              audit, provided however that no such payment or acceptance thereof
              shall be an admission that the audit determination was correct,
              and UMC SPINOFF, UMC and TI shall remain free to contest such
              determination in the manner allowed under the law.

     4.2.1    EVENTS OF TERMINATION.

         4.2.1.1  NATURAL TERMINATION. Unless extended under Section 4.1 above,
                  this Agreement (and all licenses granted under it) shall
                  expire by its terms on December 31, 2007, except that such
                  expiration shall not effect any royalty or other obligation
                  arising prior to such expiration and shall not affect any
                  rights or obligations which are specifically provided
                  hereunder as surviving expiration or termination of this
                  Agreement.

         4.2.1.2  MATERIAL BREACH. If UMC SPINOFF fails to make any payment
                  fully or timely as required by this Agreement, or in the
                  event of any other material breach of this Agreement by UMC
                  SPINOFF, and if such failure or other material breach is
                  not corrected within forty-five (45) days after written
                  notice by UMC or TI, then this Agreement may be terminated
                  by UMC forthwith in its entirety by written notice to UMC
                  SPINOFF, provided that such termination shall not affect
                  any royalty or other obligation arising prior to such
                  termination and shall not affect any rights or obligations
                  which are specifically provided hereunder as surviving
                  expiration or termination of this Agreement, and provided
                  further that as to UMC SPINOFF BRANDED PRODUCTS as to which
                  TI accepts payment of royalties, the licenses, covenants
                  and releases under this Agreement shall not be terminated
                  as to such products for which royalty payments have been
                  made by UMC and accepted by TI.

         4.2.1.3  REORGANIZATION OR SALE OF ASSETS. This Agreement may be
                  terminated by written notice of UMC to UMC SPINOFF within
                  thirty (30) days of receiving actual notice that the UMC
                  SPINOFF has consolidated with or merged with or into, or
                  transferred, directly or indirectly; all or substantially all
                  of its assets to, another corporation, company or other
                  entity; notwithstanding that UMC SPINOFF may be the surviving
                  entity of such consolidation, merger or transfer. No such
                  termination shall affect any royalty or other obligation
                  arising prior to such termination.

         4.2.1.4  GOVERNMENT INTERVENTION. If at any time during the term of
                  this Agreement, any government or agency thereof takes any
                  action against either or both PARTIES requiring, directly or
                  indirectly, formally or informally, alteration or modification
                  of any material term or condition of this Agreement or of the
                  performance of the PARTIES that materially adversely affects
                  one PARTY (the "Affected PARTY") substantially frustrating the
                  purpose of the Affected

<PAGE>

                  PARTY in entering into this Agreement, then if the Affected
                  PARTY makes written request to the other PARTY within sixty
                  (60) days from said action of such government or agency
                  thereof, the PARTIES shall enter into good faith negotiations
                  with the objective of restructuring the relationship between
                  the PARTIES in a manner such that the adverse effect of such
                  required alteration or modification of this Agreement will be
                  minimized consistent with the purposes of the PARTIES in
                  entering this Agreement as expressed herein. If the PARTIES
                  cannot reach an acceptable restructuring arrangement within
                  six (6) months from the date of such written request, or
                  within such longer period of time as mutually agreed upon,
                  either PARTY shall have the right to terminate this Agreement
                  forthwith in its entirety by giving written notice to that
                  effect to the other PARTY and such termination shall be
                  effective upon receipt of notice. All other provisions of this
                  Section 4.2 notwithstanding, in the event this Agreement is
                  terminated pursuant to this Section 4.2.1.4, then all rights
                  and licenses under TI PATENTS, TI-PARTICIPATION PATENTS,. UMC
                  SPINOFF PATENTS and UMC SPINOFF-PARTICIPATION PATENTS shall
                  cease and terminate upon receipt of such termination notice.
                  No such termination shall affect any royalty or other
                  obligation arising prior to such termination.

         4.2.1.5  TERMINATION OF LICENSE AGREEMENT. This Agreement shall
                  terminate without notice upon termination or expiration of the
                  License Agreement.

         4.2.1.6  CHANGE OF OWNERSHIP OF UMC SPINOFF. UMC SPINOFF shall give
                  prompt written notice to UMC or TI if and when any person,
                  entity, or "group" within the meaning of Section 13 of the
                  U.S. Securities Exchange Act of 1934 owns more shares of
                  stock of UMC SPINOFF entitled to vote for the election of
                  directors than are owned, directly or indirectly, by UMC
                  ("Shift in Control"). UMC will inform TI of such event, and
                  at the option of TI by written notice to UMC given within
                  forty-five (45) days of receipt of UMC's notice, or within
                  forty-five (45) days of TI learning of such Shift in
                  Control, UMC SPINOFF shall cease to be have a license to TI
                  PATENTS with respect to any wafer starts from and after the
                  date of such Shift in Control and all licenses and
                  covenants to any TI ENTITY from UMC SPINOFF shall terminate
                  as to wafer starts on or after such date, provided however
                  that if UMC and/or UMC SPINOFF sends written notice to TI
                  of the Shift in Control within forty-five (45) days of the
                  effective date of such Shift in Control, no termination
                  under this clause will take effect as to any wafers started
                  prior to the date that the UMC receives the applicable
                  written notice from TI terminating the licenses.

     4.2.2    NON-TERMINATING EVENTS. For the convenience of the PARTIES hereto,
              this Agreement is made in consideration of the exchange of patent
              licenses under a group of PATENTS of TI and its respective
              ENTITIES and UMC SPINOFF. A determination or action by a court of
              competent jurisdiction, regulatory authority or governmental
              agency: (1) finding that one or more of the PATENTS are invalid or
              unenforceable; or (2) granting a temporary or permanent injunction
              or restraining

<PAGE>

              order under one or more of the PATENTS; shall not give rise to a
              right of termination by either PARTY nor shall such determination
              or action be regarded as justification (a) for a retrospective or
              prospective change in this Agreement affecting the royalty rates
              or amounts to be paid, or (b) for changing any other provision of
              this Agreement.

     4.2.3    EFFECT OF TERMINATION. Except as otherwise provided specifically
              in Section 4.2.4, all licenses granted pursuant to this Agreement
              shall cease forthwith as of the date of expiration or termination
              for any reason of this Agreement. Any PRODUCTS as to which an
              event specified in the first sentence of Section 3.3 has not
              occurred prior to the date of such expiration or termination shall
              not be considered to be licensed under this Agreement.

     4.2.4    LICENSE SURVIVAL. In the event of termination of this Agreement or
              any of the licenses granted under this Agreement by one party
              ("the Terminating PARTY") pursuant to Section 4.2.1.2, the
              licenses granted by the defaulting PARTY and its respective
              ENTITIES to the Terminating PARTY and its respective ENTITIES
              hereunder shall survive until December 31, 2007.

6.14  CONVENIENCE OF THE PARTIES. The PARTIES hereto understand and agree that
      the royalty payments to be made by UMC SPINOFF hereunder are based on
      royalty rates applied to all purchases from UMC ENTITIES by UMC SPINOFFS
      of all UMC SPINOFF BRANDED PRODUCTS in any country in the world regardless
      of whether or not a TI ENTITY has any patent in any particular country and
      regardless of whether there is any use of any TI PATENTS in certain
      countries. It is further understood that this is specifically done for the
      convenience of the PARTIES and their respective ENTITIES, so that separate
      accountings do not have to be made and separate license agreements do not
      have to be negotiated for all PATENTS and for each country in which the
      PARTIES or their respective ENTITIES hold or may hold PATENTS and do
      business.
