         This Agreement is made by and between Texas Instruments Incorporated
("TI"), a Delaware corporation having a place of business at 8505 Forest
Lane, Dallas, Texas 75243, U.S.a., and United Microelectronics Corporation
("UMC"), a corporation organized under the laws of the Republic of China
having a place of business at No. 3 Li Hsin Road 2, Science Based Industrial
Park, Hsin Chu City, Taiwan. Unless otherwise defined herein, defined terms
shall have the meanings assigned thereto in Exhibit a hereto.

                                   WITNESSETH:

         WHEREAS, the TI ENTITIES own or control and have or may have in the
future rights under various patents and utility models and applications in
various countries of the world as to which the UMC ENTITIES desire to acquire
licenses as hereinafter provided;

         WHEREAS, the UMC ENTITIES own or control and have or may have in the
future rights under various patents and utility models and applications in
various countries of the world as to which the TI ENTITIES desire to acquire
licenses as hereinafter provided;

         WHEREAS, the TI ENTITIES and the UMC ENTITIES recognize that the
patent portfolios of each can, and will change, virtually on a daily basis,
as new patents are added and existing ones expire, in various countries of
the world, during the term of this Agreement, and both desire to enter into a
cross-license that would include, as licensed under this Agreement, [*] each
at any time existing during the term of this Agreement (a "portfolio
cross-license");

         WHEREAS, the TI ENTITIES and the UMC ENTITIES acknowledge that it is
their mutual intent and desire to enter into this portfolio cross-license form
of agreement as a result of and taking into consideration, among other things:

         (A)      The continuous updating of products in the semiconductor
                  industry resulting from rapid technological advances;

                  the standard and custom of the semiconductor industry to
                  enter into, and rely on, portfolio cross-license agreements;

         WHEREAS, the TI ENTITIES and the UMC ENTITIES are engaged in
continuing research, development and engineering in regard to PRODUCTS and

         WHEREAS, TI and UMC acknowledge that they are entering into a
portfolio cross-license, and not a license for specific patents;

         WHEREAS, TI and UMC have settled on a means to govern the payment of
royalties during the term of this Agreement having taken into account the
patent portfolios of the TI ENTITIES and the UMC ENTITIES, good faith
negotiations involving selected patents and product lines of the TI ENTITIES
and the UMC ENTITIES, and the fact that UMC will pay royalties hereunder for,
among other things, making UMC FOUNDRY PRODUCTS for customers, some of whom
will not have licenses from a TI ENTITY, as well as some who may;

         WHEREAS, TI and UMC acknowledge and contemplate, in view of the fact
that a [*] of this portfolio cross-license Agreement is to provide the TI
ENTITIES and the UMC ENTITIES, except for certain excluded patents, with [*]

         WHEREAS, TI and UMC find it convenient to make an arrangement
whereby [*] the patents of the TI ENTITIES and of the UMC ENTITIES with
respect to [*] PRODUCTS, are made accessible to the other under [*] license [*],
and therefore, they desire to enter into [*] patent license agreement on the
terms hereinafter set forth and to make the payments described herein; and

         WHEREAS, as part of the licensing arrangement, the UMC ENTITIES
desire to obtain and the TI ENTITIES are willing to grant licenses on the

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.

                       This Agreement sets forth the full and complete
agreement and understanding between the PARTIES as to the subject matter of
this Agreement and merges all prior discussions and writings (including, but
not limited to, the Memorandum of Understanding dated August 28, 1998)
between them as to the subject matter hereof. There are no representations,
understandings or agreements, oral or written, between TI and UMC as to the
subject matter of this Agreement which are not expressly included herein.
Neither of the PARTIES shall be bound by any modification of this Agreement,
other than as expressly provided in this Agreement or as duly set forth on or
subsequent to the date hereof in writing and signed by a duly authorized
representative of both PARTIES.
         5.15     BASIS FOR AGREEMENT
                           The PARTIES acknowledge that they have entered into
this Agreement of their own free will, and have not relied on any inducement

                           The failure by a PARTY or its ENTITIES to exercise
any of its rights under this Agreement shall not be deemed to constitute a
waiver of any of such rights, or other rights or remedies available to such
PARTY. In particular, and subject to the terms of this Agreement, the
subsequent acceptance of royalty payment(s) by TI shall not be deemed a
waiver of any prior default by UMC regardless of TI's knowledge of such prior
default at the time of acceptance of such royalty.

         5.17     CONVENIENCE OF THE PARTIES
                           The PARTIES hereto understand and agree that the
royalty payments to be made by UMC hereunder are based on royalty rates
applied to all sales or use by UMC ENTITIES (whether to third parties or to
UMC SPINOFFS) of all ROYALTY BEARING 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.

     IN WITNESS WHEREOF, the PARTIES have caused their duly authorized
officers to execute this Agreement, on the dates below indicated.

<PAGE>

         (1)   Total worldwide sales revenue (less the deductions in (i)

      clause a. above divided by the total units of that product so sold,
      leased or otherwise disposed of anywhere in the world during said
      calendar semiannual reporting period to any person or entity other than
      a UMC ENTITY, to determine the average sales price per unit for such
      same or similar product. Such average sales price per unit shall be
      multiplied by the total units of such particular ROYALTY BEARING
      PRODUCT for which NET SALES BILLED are calculated under this clause b.
         (2)   For each such same or similar product that has no sales revenue
      under clause a. above for the reporting period, fair market value
      shall be the SAME value as the average sale price (calculated in the
      manner provided in clause b.(1) above) as reported for such same or
      similar product in the immediately preceding calendar semiannual
      reporting period or, if there were no value established for the
      immediately preceding reporting period, then the fair market value, as
      determined above, shall be applied for the average sales price of the
      nearest related standard part offered by any of the UMC ENTITIES, that
      substantially performs the same functions as such same or similar
      product.
         (3)   If a plurality of ROYALTY BEARING PRODUCTS are assembled onto a
      printed circuit board or otherwise are similarly configured
      (hereinafter called the "Assembled Products") and used or incorporated
      in the manner for which NET SALES BILLED are required to be calculated
      as set forth in this clause b., the fair market value of each ROYALTY
      BEARING PRODUCT incorporated in Assembled Products shall be used for
      the purpose of this Agreement.
      c.   NET SALES BILLED shall be accounted for in accordance with Section
2.1.8 of the Agreement.
