Item 5.   Other Events

     Lattice Semiconductor Corporation (the "Company") signed a definitive
agreement on September  14,  1995  with United Microelectronics Corporation
("UMC") to join several other fabless semiconductor companies in a previously
announced venture to form a separate Taiwanese company for the purpose of
building and managing an advanced semiconductor manufacturing facility in Hsin
Chu City, Taiwan, Republic of China.

     Under terms of the agreement, the Company will invest $60 million, payable
in three installments over the next two years, for a 10% equity interest in the
venture.  The proposed facility is expected to commence production of eight-inch
sub-micron wafers during the second half of 1997.  UMC will transfer its 0.5
micron, and when developed, its 0.35 and 0.25 micron process technologies to the
venture on a royalty free basis.  As a result of its equity ownership, the
Company will receive rights to a percentage of the wafer production from the new
facility.  Formation of the venture is subject to a number of conditions:
including arrangement of the necessary debt financing and obtaining requisite
government approvals.

     In a related arrangement, UMC has committed to supply the Company with sub-
micron wafers beginning in the first calender quarter of 1996 and continuing,
with phased increases, until such capacity is available from the new facility.

President
Lattice Semiconductor Corp.

Dear Mr. Tsui:

     As promised yesterday, UMC commits the combined capacity amounts from UMC
and from the foundry ventures in the following specific quantities:

*

Notes: 1)   All amounts are conditioned upon Lattice's signatures on and
            payments under the Foundry Venture and Foundry Capacity Agreements
            for Module D.
       2)   All are 6 inch equivalents in wafer starts per month w/normal cycle
            time.
       3)   For all amounts, UMC calculates 1.9 six inch wafers are equivalent
            to each eight inch wafer.
       4)   The amounts shown are cumulative for the periods involved of all
            quantities supplied from UMC fabrication facilities and/or joint
            ventures.
        5)  The pricing for this capacity shall be as agreed by the parties,
            with a maximum Wafer price of * of UMC's standard CMOS logic
            processes for wafers of similar geometrics, purchase volumes
            and cycle times.


As mentioned, this letter commitment is contingent upon Lattice entering into
the Foundry Venture Agreement and Foundry Capacity Agreement on or before
September 13, 1995.  As agreed, all wafer purchases under this Bridge Capacity
Letter shall be handled under the procedures and subject to the specific
provisions of the Foundry Capacity Agreement, or as otherwise agreed in writing
between UMC and Lattice.

     In addition, please rest assured that UMC will work diligently to bring
up the processes provided by Lattice in as prompt a manner as is commercially
and technically practicable.  To the extent that our implementation of your
processes takes longer than expected for reasons attributable to UMC and/or
our personnel, *.  As discussed and unless otherwise agreed, we will provide
the capacity in this commitment from a * (with each of us cooperating during
the transition from UMC to the new venture's facility).

     Finally, and without limiting the obligations under the confidentiality
provisions of the Foundry Venture Agreement, FabVen and UMC will treat as
confidential all processes provided by Lattice which are designated by Lattice
as "Confidential" as provided by the procedures stated in the Foundry Venture
Agreement, and, without the written consent of Lattice, neither FabVen nor UMC
shall use or otherwise disclose any such process for any purpose other than the
fabrication of wafers for Lattice.  UMC and Lattice anticipate they will enter
into an appropriate non-disclosure and restrictive use agreement with respect to
such information so that each party is reasonably protected with respect to its
proprietary information.

CONFIDENTIAL                                      Bridge Capacity Letter




     We understand that you are relying upon this Bridge Capacity Letter in
entering into the Foundry Venture and Foundry Capacity Agreements, as well as
for planning your future wafer capacity supply and, in turn, commitments to
other customers.  We also confirm that the provisions of the letter entitled
"Written Assurances Re: Foundry Venture Agreement" for the venture at Module D
will be the same as that for Module C, that, upon signature by Lattice, that
letter will be an enforceable agreement between UMC and Lattice, and, upon
execution of all Venturers, that letter shall be treated as an amendment to
those agreements.

     We value Lattice's participation and look forward to a very successful
venture.


                                                  Yours sincerely,


                                                  Peter Chang

                WRITTEN ASSURANCES RE:  FOUNDRY VENTURE AGREEMENT


     At the suggestion of several venturers, UMC is pleased to confirm in
writing the following points concerning the Foundry Venture Agreement and the
Foundry Capacity Agreement.  Where these commitments require the consent of
FabVen, UMC will exercise its influence and commit best faith efforts to secure
that consent.

1.   ALL VENTURERS ARE OFFERED EQUAL TERMS
     As stated in the Foundry Venture Agreement, the terms of investment and of
wafer purchases to each Venturer under the Foundry Venture Agreement and under
the Foundry Capacity Agreement are the same, except for the percentages of
ownership and capacity rights of each Venturer [capacity rights for Venturers
are equal to * times the percentage of ownership]; provided however that
Venturers who commit to a minimum of * will have the right to appoint a
representative to a seat on the board of directors for the initial three year
term.

2.   ACCESS TO BOARD MEETINGS & BOARD MEMBERS
     Subject to the obligations of Confidentiality imposed under the Foundry
Venture Agreement, the Foundry Capacity Agreement, and/or the Technology
Transfer and License Agreement ("Venture Agreements"), and to the requirements
of law, each Venturer will be given reasonable notice of meetings of the board
of directors of FabVen, and the opportunity to have a representative attend such
meetings and communicate at such meetings with the board members in connection
with matters concerning FabVen.

3.   MEMBERSHIP ON FABVEN BOARD--FIRST THREE YEARS AND BEYOND
     The board of directors of FabVen will be comprised of seven members.  Of
these seven members, * will be appointed by UMC for an initial three year
term, * will be appointed by the R.O.C. financial institutions which invest in
FabVen for an initial three year term, and the other * board members will be
appointed for an initial three year term by the Venturers other than UMC under
procedures to be mutually agreed upon by such Venturers, provided that any
Venturer who holds at least * of the shares of FabVen will be entitled to
appoint * of such other * board members.  After the initial three year term,
the board will be elected by the shareholders pursuant to R.O.C. law in the
manner provided in the bylaws.

4.   STRATEGIC ACTIONS SUBJECT TO SPECIAL BOARD APPROVALS
     Subject to the other requirements of the law, and for so long as the
Venturer involved remains in compliance with all payment obligations under the
Foundry Venture Agreement and such Venturer retains at least * of the
ownership percentage in FabVen as listed in Paragraph 4.1 of the Foundry Venture
Agreement, all board actions directly deciding strategic technical issues
[including without limitation, the type of process technology (such as that used
in the manufacture of *) to be


                                       -1-



      * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE
                        SECURITIES AND EXCHANGE COMMISSION

developed, implemented and/or offered by FabVen, the amendment of the Technical
Transfer and License Agreement, and/or the transfer or licensing of technology
developed by FabVen to others (except as contemplated under the Technology
Transfer and License Agreement)] shall not be effective unless and until
approved by at least * of the board members designated by the Venturers other
than UMC, and (ii) all board actions authorizing liquidation of FabVen, merger
of FabVen, sale of all or substantially all of FabVen or of FabVen's assets,
and/or the offering of any equity (except pursuant to a public offering of
FabVen  shares on a recognized securities exchange) shall not be effective
unless and until approved by * board members designated by the non-UMC
Venturers under the terms of the Foundry Venture Agreement.

5.   NO UNAUTHORIZED CHANGES TO TECHNOLOGY ROADMAP
     For so long as the Venturer involved remains in compliance with all payment
obligations under the Foundry Venture Agreement and such Venturer retains at
least one half of the ownership percentage as listed in Paragraph 4.1 of the
Foundry Venture Agreement, FabVen shall not make any material changes to the
Technology Road Map as shown in Attachment A which affect such Venturer's
existing and/or planned production without the consent of that Venturer.

6.   CONDITIONAL "PUT" RIGHT
     To the extent that FabVen fails (i) to qualify silicon manufactured with
* processes each having a minimum of * feature sizes under a test vehicle to
be agreed upon by FabVen, UMC and a majority of the Venturers other than UMC
(including without limitation, a test vehicle from a Venturer, provided that
such qualification under a test vehicle from a Venturer is commercially
reasonable and within industry standards) ("First Qualification") on or
before the end of December 31, 1998, and/or (ii) to achieve the ability to
manufacture a minimum of * wafer outs per month for such * process and *
wafer outs per month for such * process on or before December 31, 1998  for
reasons attributable to UMC, FabVen and/or the Licensed Processes,  the
Venturers (one or more of them) will have the option to sell their shares
(and their corresponding rights to capacity in FabVen) to UMC for the total
amount they paid for such shares by sending written demand to UMC as follows:

     (a)  No such demand shall be effective unless it is made on or before April
1, 1999; and

     (b)  Within ninety days of such written demand from the Venturer involved,
UMC will buy the shares (and capacity rights) involved, and/or arrange another
buyer willing to purchase such shares (and capacity rights) under the terms and
conditions as stated in this heading.

7.   RELEASE OF SHARE TRANSFER RESTRICTION IF NO PUBLIC OFFERING
     To the extent that FabVen does not offer its shares in a public offering on
a recognized securities exchange on or before  December 31, 2006, and
notwithstanding anything to the contrary, each Venturer other than UMC will have
the right to transfer its entire right and interests in FabVen as follows:

     (a)  The Venturer wishing to transfer ("Transferring Venturer") shall send
the other Venturers (including UMC) written notice of its intention to transfer,
stating in such notice the general terms and payment contemplated by such
Transferring Venturer;


                                       -2-



       * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE
                        SECURITIES AND EXCHANGE COMMISSION

     (b)  Within thirty days (the "Transfer Notice Period") of such notice,  any
one or more such other Venturers may send a written offer to purchase such
Transferring Venturer's interest under terms to be stated in the written offer
[for purposes of this Paragraph, each other Venturer making such an offer shall
be referred to as the "Offering Venturer"];

     (c)  If no other Venturer makes such an offer within the Transfer Notice
Period, then, subject to subpart (g) below, the Transferring Venturer shall be
allowed to transfer its entire interest and ownership in FabVen to other
purchasers.

     (d)  If  any Offering Venturer makes such an offer within the Transfer
Notice Period, the Transferring Venturer and the Offering Venturer will
negotiate in good faith concerning each such offer for not less than thirty days
(the "Transfer Negotiation Period").

     (e)  If by the end of the Transfer Negotiation Period and despite such
negotiations, the Transferring Venturer has not reached agreement with the
Offering Venturer(s) for sale of the Transferring Venturer's interest, then,
subject to this Paragraph (and all of its subparts), the Transferring Venturer
shall be allowed to transfer its entire interest and ownership in FabVen to
other purchasers.

     (f)  Notwithstanding anything to the contrary, no Transferring Venturer
shall be allowed to accept from any  third party any offer with price and terms,
taken together, which are less favorable than last offered in writing by an
Offering Venturer during the Transfer Notice and/or Transfer Negotiation
Periods, unless such Transferring Venturer first offers the same price terms to
such Offering Venturer in writing, and allows such Offering Venturer ten
business days to accept or reject such price and terms.

     (g)  Except as permitted in paragraph 4.1(f) of the Foundry Venture
Agreement and/or in Paragraph 15 of this Written Assurance, no Venturer may
transfer its interest or right in FabVen under this paragraph or otherwise in
any manner to any competitor of UMC or to any entity in the business of
fabricating integrated circuits except under terms (i) in which such Venturer
first relinquishes and releases all rights to FabVen capacity and to designate
membership on the FabVen board of directors under this and any and all other
agreements, and (ii) in which such entity and/or competitor expressly consents
in writing that they have no such interest or right to such capacity and/or
designation.

8.   TECHNOLOGY TRANSFER AND LICENSE CONDITION TO FIRST PAYMENT
     Notwithstanding anything to the contrary, the execution of the Technology
Transfer and License Agreement in the form presented to the Venturers as of
September 15, 1995 shall be a condition precedent to any payment of investment
amounts pursuant to the Foundry Venture Agreement.

9.   CLARIFICATION OF * CONDITION TO THIRD INSTALLMENT
     Notwithstanding anything to the contrary, the milestone for the third
investment payment milestone shall be on or before * as that phrase is
generally understood and interpreted in the industry.

                     SECURITIES AND EXCHANGE COMMISSION


10.  USE OF INVESTMENT MONIES
     Unless otherwise agreed by each Venturer, FabVen will use all funds
invested by the Venturers pursuant to paragraph 4.1(b) of the Foundry Venture
Agreement solely as outlined in and consistent with the FabVen Business Plan.

11.  RIGHTS OF FIRST REFUSAL ON SUBSEQUENT OFFERINGS
     FabVen will provide the Venturers with notice reasonable under the
circumstances in order to enable them to exercise their rights of first refusal
in connection with equity offerings pursuant to paragraph 4.1(g) of the Foundry
Venture Agreement.


12.  VESTING OF TECHNICAL SHARES
     UMC's technical shares will not vest under paragraph 4.1(d) of the Foundry
Venture Agreement until FabVen produces wafers with the * process (as
that phrase is defined in general industry usage) with sufficient yield to be
recognized as "production ready" within general industry usage.

13.  AUDIT RIGHTS
     The specific wording of the provisions contemplated under paragraph 4.2 of
the Foundry Venture Agreement with respect audit rights and financial
information will be as stated by Price Waterhouse, with their commitment to
prepare the reports as promptly as possible under the circumstances.  The exact
language for the audit rights will be modeled on whatever Price Waterhouse and
the other accountants agree upon in connection with the joint venture announced
with UMC, Alliance and S3.  Currently, it is contemplated that the financials
will be prepared in a manner consistent with that imposed on U.S. public
companies for minority interests.

14.  TERMS FOR RIGHTS OF FIRST REFUSAL UNDER PARAGRAPH 4.1(f)(iv)
     The rights of first refusal under Paragraph 4.1(f)(iv) of the Foundry
Venture Agreement are intended to extend to and benefit all other eligible
Venturers.  To avoid any ambiguity, 4.1(f)(iv)(cc) and 4.1(f)(iv)(dd) are to be
interpreted as follows:

        (cc)   if any such eligible other Venturer elects not to exercise any
        portion or all of such right of first refusal within 30 days of the
        independent appraisal, such portion of such right of first refusal will
        be subject to exercise by the other eligible other Venturers in
        proportion to their then existing shareholdings in FabVen, and the
        shares involved will be subject to a right of such other eligible other
        Venturers to purchase on the same terms as outlined above; and

        (dd)   if any such other eligible other Venturer does not commit to
        purchase such shares within 60 days of the independent appraisal, all
        rights under this Paragraph 4.1(f)(iv) will expire as to such
        unpurchased shares.


15.  TRANSFERS OF SHARES AFTER PUBLIC OFFERING
     Nothing in Paragraph 6.2(c)(i) of the Foundry Venture Agreement or
elsewhere shall prohibit a Venturer from offering and/or selling its shares in
FabVen on the public market to a competitor of UMC, provided however that such
competitor must relinquish all rights to representation and access to Board
information under the Foundry Venture Agreement and under this Written
Assurance, and provided that the restrictions of Paragraph 6.2(c)(ii) of the


                                       -4-



    * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE
                     SECURITIES AND EXCHANGE COMMISSION

Foundry Venture Agreement and of Paragraph 7 of this Written Assurance shall
still apply, and provided further that the other restrictions concerning
transfers of capacity and reductions in capacity on a proportional basis with
reductions in ownership will also apply.

16.  TRANSFERS OF CAPACITY AMONGST VENTURERS
     Notwithstanding anything to the contrary, the Venturers in Module D may
each transfer their respective capacities (whether or not previously forecast)
as stated in Paragraph 2.1 of the Foundry Capacity Agreement to and between one
another by written notice to FabVen and the other Venturers, provided that such
written notice must state the capacity amounts so transferred and the months in
which such transfer will apply and provided that FabVen's consent (which must
not be unreasonably withheld) shall be required for a transfer of quantities
previously committed under Paragraph 2.3(b) of the Foundry Capacity Agreement.
To the extent that FabVen receives such written notices * or more days
prior to the beginning of each month in which such capacity is to be
transferred, such capacity will be treated as if allocated to the Venturer to
whom it has been transferred for all purposes for the period of the transfer
involved, including, without limitation, for purposes of forecasts, commitments,
and the right of FabVen to commit to others any capacity unexercised by the
Venturers.

17.  * WARRANTY
     The warranty period as stated in Paragraph 5.1 of the Foundry Capacity
Agreement, and the claim period as stated in Paragraph 5.3 of the Foundry
Capacity Agreement shall each be *.

18.  CLARIFICATION OF PARAGRAPH 5.4 OF THE FOUNDRY CAPACITY AGREEMENT
     The limitations of paragraph 5.4 of the Foundry Capacity Agreement are
intended to limit the remedies under the Warranty provisions, Section 5 of the
Foundry Capacity Agreement.  Thus, the Paragraph will be understood and
interpreted as follows:

THIS PARAGRAPH 5.4 STATES THE ONLY AND EXCLUSIVE REMEDY FOR ANY AND ALL CLAIMS
MADE AGAINST FABVEN UNDER THIS SECTION 5 OF THIS FOUNDRY CAPACITY AGREEMENT.

19.  CONFIRMATION OF "COVER" REMEDY
     To the extent an intentional breach by FabVen of its obligations concerning
wafer start and/or delivery under the Foundry Capacity Agreement results in a
delay of more than * days in delivery of Wafers to a Venturer, then,
notwithstanding anything to the contrary, at the election of the Venturer,
FabVen will compensate such Venturer for reasonable damages of such Venturer in
securing substitute or cover Wafers for those involved in the breach, subject to
the limitation stated below.  In addition, to the extent that FabVen breaches
its warranties under Section 5 of the Foundry Capacity Agreement, and fails, for
reasons attributable to a breach by FabVen or the Licensed Process to correct
such breach after two successive attempts to do so, then, at the election of the
Venturer, FabVen will compensate such Venturer for reasonable damages of such
Venturer in securing substitute or cover Wafers for those involved in the
breach, subject to the limitation stated below.  Notwithstanding anything to the
contrary, for purposes of this commitment in Paragraph 19 of this Written
Assurance, the recoverable substitute and/or cover damages shall be (i) the
reasonable and necessary costs to replace mask sets for the products involved,
together with (ii) the difference between (aa) the price which the Venturer
would have paid for the Wafers had FabVen fully performed (the "contract
price"), and (bb) all direct and reasonable costs (up to a maximum of * of
the contract price) incurred by the Venturer in securing substitutes and/or
cover.

     Notwithstanding anything to the contrary under any local real estate or
other law, custom or practice, UMC will consider all investments, improvements
and fixtures purchased by FabVen to be the property of FabVen, and UMC will not
request higher rents under the lease of Module D as a result of any such
investment, improvement and/or fixture.  In addition, at the request of FabVen,
UMC will negotiate in good faith with FabVen over additional extensions of the
lease term beyond the fifteen year period contemplated under the Foundry Venture
Agreement, and, to the extent that UMC retains the underlying right to do so,
UMC will renew the lease to FabVen for the land of Module D for subsequent five
year terms continuing until the term (or partial term) ending *.
Without limiting the terms of the Foundry Venture Agreement, the lease rate for
the land for Module D will be proportional to the amount paid by UMC to the Park
Administration for the respective square footage involved, plus a reasonable
amount to cover overhead directly related to the lease (not to exceed * of the
rate for the respective share).

21.  CONTINUED ASSISTANCE BY UMC
     Notwithstanding anything to the contrary, UMC will continue to provide
technical assistance to FabVen with respect to the Licensed Processes to the
extent and for the period reasonably necessary to permit each Venturer to
qualify its products on each Licensed Process which is suitable for the
production of such products.  In addition, UMC will make good faith efforts to
improve and develop UMC technology so as to enable UMC to provide that
technology to be provided to FabVen by UMC as shown in the Technology RoadMap.

22.  CHOICE OF LAW--NO "HIDDEN" MEANINGS
     To the extent any aspect of Taiwan law purports to alter the express
meaning of any term of the Technology Transfer and License Agreement, such term
will not be governed by Taiwan law, but instead will be governed by California
law so as to give effect to the express intention of the parties as stated in
that agreement.

the arbitrators will have the power to require discovery in connection with any
dispute within their jurisdiction pursuant to the Federal Rules of Civil
Procedure to the extent they find such discovery necessary to achieve a fair and
equitable result, and subject to reasonable orders from the arbitrators to
minimize the burdens involved and to focus the discovery on those areas
necessary.  All reasonable costs of such discovery (including attorneys' fees)
incurred by a party which prevails in the arbitration in connection with the
issue involved in the discovery will be recoverable by that party against the
party which requested the discovery.

"Production Capacity Percentage"):

- ----------------------------------------------------------------------
Venturer                           Production Capacity Percentage
- ----------------------------------------------------------------------
Lattice                            *
- ----------------------------------------------------------------------
OtherVen                           TBD%
- ----------------------------------------------------------------------

Provided however that during any period when any Venturer's total FabVen
shareholding falls below one-half of their initial percentage of the total
outstanding FabVen shares under the terms of the Foundry Venture Agreement, such
Venturer's Production Capacity Percentage shall instead be equal to the
percentage of the then total outstanding shares of FabVen then held by such
Venturer.

2.2  During the first * calendar days of each month during the term of this
Foundry Capacity Agreement, FabVen will provide by facsimile to the Venturers
written rolling forecasts of FabVen's anticipated Production Capacity for the
next six full calendar months.  These Production Capacity forecasts will not be
commitments or representations that FabVen will achieve the quantities stated,
but will be FabVen's best estimates of the quantities involved.

2.3  Subject to Paragraph 2.1, within * calendar days of receipt of each
Production Capacity forecast under Paragraph 2.2 above during the term of this
Foundry Capacity Agreement, each Venturer will provide to FabVen by facsimile a
written rolling forecast of its wafer capacity requirements from FabVen for the
next six full calendar months ("forecast" and/or "six months wafer start
requirements forecast").

     (a)  Each such forecast shall show the quantity of wafer starts and shall
include the specific technology for the wafers listed.  Each Venturer shall make
good faith efforts to ensure that all such forecasts are reasonable estimates of
their respective anticipated needs.  Subject to this obligation, and except as
expressly stated in this Paragraph 2.3, all such forecasts (and any responses to
them) will be for planning purposes only, and will not create any obligation to
purchase and/or sell Products.

     (b)  Each such six months wafer start requirements forecast shall
constitute a commitment by the Venturer to purchase a minimum of the following
percentages of the amounts indicated in the forecast:

- ----------------------------------------------------------------------------------------------------------------------------------- Month in the First month of Second month Third month of Fourth month Fifth month of Sixth month forecast forecast of forecast forecast of forecast forecast of forecast - ----------------------------------------------------------------------------------------------------------------------------------- Minimum percentage commitment for * * * * * * amo unts forecast for that month - -----------------------------------------------------------------------------------------------------------------------------------
(c) FabVen shall provide a written response to each six months wafer start requirements forecast within * working days of FabVen's receipt of such forecast. Subject to the other terms of this Foundry Capacity Agreement, FabVen's response to each such forecast shall 2 * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE SECURITES AND EXCHANGE COMMISSION accept the forecast for the quantities in the first * months to the extent they are within the amounts allowed for the Venturer involved pursuant to Paragraph 2.1. FabVen's response may accept and/or reject in whole or in part any additional forecast quantities for those months. 2.4 Subject to Paragraphs 2.7 and 9.5 of this Foundry Capacity Agreement, to the extent that any forecast from any Venturer pursuant to Paragraph 2.3 fails to forecast the full "Production Capacity Percentage" of FabVen Production Capacity allocated to that Venturer under Paragraph 2.1 above during any one or more of the first * months of such forecast: (i) by sending prompt written notice of the amount involved to the Venturer affected, FabVen shall be entitled in its sole and complete discretion to enter commitments with others for such unexercised capacity for the applicable months and in the amounts not so exercised, and (ii) such Venturer will not have the right to require FabVen to provide that unexercised capacity to that Venturer in the month(s) involved. 2.5 Notwithstanding anything to the contrary, FabVen will have no obligation to offer additional capacity beyond that stated in Paragraphs 2.1, 2.3 and 2.4 above and/or Paragraph 2.7 below to any Venturer. Nevertheless, during the term of this Agreement, each Venturer shall be entitled to negotiate with FabVen for such capacity on the same basis as others are permitted to negotiate. 2.6 Each Venturer may exercise rights of first refusal for foundry capacity under this Foundry Capacity Agreement solely for Products, and not for the purpose of offering or providing foundry capacity to others. Except as expressly provided below and/or in the Foundry Venture Agreement, no Venturer may transfer and/or assign its rights to capacity under this Foundry Capacity Agreement. 2.7 The Venturers will discuss in good faith the capacity needs of one another with respect to FabVen facilities and Production Capacity. 2.8 Notwithstanding anything to the contrary, and in addition to any other remedies or rights, in the event of any delays in delivery, or any breach of any warranty provided by FabVen under Section 5, any affected Venturer may adjust forecasted and/or ordered Product amounts, and/or cancel orders for affected Products, without breach of any minimum commitment obligations hereunder to take into account the impact of such delay on the Venturer's need for affected Products. 3. PRICING AND DELIVERY 3.1 All purchases of foundry services by the Venturers pursuant to this Foundry Capacity Agreement will be subject to FabVen's standard terms and conditions and its usual business practices, subject to any contrary requirements expressly imposed pursuant to the terms of this Foundry Capacity Agreement. 3.2 Except as expressly provided in this Foundry Capacity Agreement, all purchases of foundry services by the Venturers during the term of this Agreement will be at * and 3 * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE SECURITES AND EXCHANGE COMMISSION *; provided however that if all Venturers consent in writing, FabVen may, prior to the completion of an offering of its shares on a recognized securities exchange, offer foundry service terms to the Venturers on such other terms as may be so expressly agreed. 3.3 For so long as the Venturer involved has a right to FabVen Production Capacity under Section 2.1 above, the prices and other purchase terms to such Venturer for foundry services from FabVen will be no less favorable than the prices and purchase terms which FabVen offers to any other entity for comparable processes and Products at comparable quantities; provided however that *. 3.4 FabVen shall make its best efforts to achieve on-time delivery, and will make reasonable efforts to provide linear shipments. To the extent that FabVen complies with its commitments for wafer starts pursuant to the terms of this Foundry Capacity Agreement, and thereafter makes such efforts, FabVen shall not be liable to any Venturer for any delay in delivery. 4. RELIABILITY AND QUALITY 4.1 Subject to the terms of FabVen's standard Non-Disclosure Agreement (the terms of which will be no more onorous than as stated in the Foundry Venture Agreement), FabVen will provide, upon written request of a Venturer, its available reliability and quality data regarding Products for the purpose of maintaining consistent quality and reliability standards for such Products throughout the term of this Foundry Capacity Agreement. 4.2 FabVen shall give the Venturers advance written notice of any proposed change(s) ("Proposed Change Notice") in materials and/or to its existing manufacturing process, which, to the best of FabVen's knowledge, might affect the form, fit, performance, maintainability, operation, function, reliability, interface, interconnectability, compatibility, design rules, models, or size of the chips for Products. Such Proposed Change Notice shall describe the nature of the proposed change(s), including reasons for the change(s), the anticipated schedule for implementation of the change(s), and other relevant technical and logistic considerations, including without limitation quality and reliability data to the extent available. The Venturers shall approve or disapprove any such proposed change promptly, but in no event may any such change be disapproved later than * business days after receipt of the Proposed Change Notice. If any Venturer disapproves such proposed change within the * business day period allowed, FabVen shall continue to manufacture and deliver to such Venturer unchanged Products in accordance with this Foundry Capacity Agreement for a minimum of * from the date FabVen issues the Proposed Change Notice. Upon the expiration of * after the following Proposed Change Notice, FabVen, in its discretion and by then giving a minimum of * prior written notice to the Venturer, may stop manufacture and delivery of the Product involved without liability. 4 * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE SECURITES AND EXCHANGE COMMISSION 4.3 Subject to the other terms of this Foundry Capacity Agreement, the Venturers reserve the right to make any changes they deem appropriate to the design of Products to be fabricated for them by FabVen, provided however that each such change must be documented by the Venturer through written change notices. Notwithstanding anything to the contrary, after process qualification runs for a particular Product have been made and approved by those involved, any changes to design, process or materials for such Products requested by the Venturer shall be subject to FabVen's consent (which will not be unreasonably withheld) and payment by the Venturer of applicable reasonable costs, if any, related to such change. 4.4 During the term of this Foundry Capacity Agreement, FabVen shall maintain fab and test lot traceability for Products manufactured hereunder. 4.5 FabVen will promptly after discovery advise the Venturers involved of defects and/or non-conformity in Products already shipped to and/or in lots currently in manufacture for such Venturer(s). During the term of this Foundry Capacity Agreement, FabVen will provide each Venturer with written quarterly quality assurance reports regarding Products manufactured on behalf of that Venturer. 4.6 Wafer acceptance will be subject to process control monitor acceptance criteria to be mutually agreed upon between FabVen and the applicable Venturer on a process-by-process basis. Minimum yield and low yield lot criteria will be negotiated between FabVen and the applicable Venturer on a Product-by-Product basis. 5. WARRANTY AND ACCEPTANCE 5.1 FabVen warrants that the Products delivered will be free from defects in material and workmanship for a period of * following delivery by FabVen, and will be processed according to FabVen standard processing specifications as well as in accordance with any additional processing requirements for such Products as may be agreed-upon in writing by FabVen and the Venturer. FabVen warrants that the Venturer will acquire good title to the Products fee and clear of all liens, claims and encumbrances (other than liens, claims and encumbrances relating to alleged intellectual property infringement). 5.2 Upon receipt of written Stop Request, FabVen will immediately stop shipment of Products which are subject to a suspected failure to meet the criteria specified in Paragraph 5.1. If FabVen is responsible for such failure, or the Products in question are not in conformity with Paragraph 5.1, and FabVen is unable to correct it within * of receipt of such a written Stop Request, then the Venturer involved may reject non-conforming Products which are subject to the failure, and, without penalty (including loss of capacity) cancel any then-committed but not yet shipped purchase order for such Products by sending written notice of cancellation to FabVen within * of the written Stop Request. Such a notice of cancellation shall be effective on receipt by FabVen. 5.3 Products which are the subject of warranty claims shall be returned in component form (removed from boards where applicable) to FabVen pursuant to FabVen standard return 5 * OMITTED PURSUANT TO A CONFIDENTIAL TREATMENT REQUEST FILED WITH THE SECURITES AND EXCHANGE COMMISSION material authorization procedures. No warranty claim concerning Products, under this Foundry Capacity Agreement or otherwise, may be made more than four months after delivery by FabVen of the Products which are subject to the claim. 5.4 To the extent that any Product delivered under this Foundry Capacity Agreement fails to meet the warranties and/or requirements provided herein, and FabVen shall either (a) replace such Product not meeting the warranty with an equivalent number of replacement Products without charge, or (b) refund the payments made to FabVen for such Product, all within * of receipt by FabVen of written notice from the Venturer of such non-conformin Products. The parties will discuss in good faith which of these two remedies is the most appropriate; provided however that if they cannot agree, FabVen shall have the option to choose in its sole discretion between the two remedies, and provided further that no refund and/or replacement shall be required unless the Products for which refund and/or replacement is sought are returned to FabVen pursuant to FabVen's return material authorization procedures. THIS PARAGRAPH 5.4 STATES THE ONLY AND EXCLUSIVE REMEDY FOR ANY AND ALL CLAIMS MADE AGAINST FABVEN UNDER THIS FOUNDRY CAPACITY AGREEMENT. 5.5 FabVen shall not be responsible for defects to the extent caused by assembly not performed by FabVen or by design or application, or by combination of Products with other components. 5.6 The exclusions and warranties in this Section 5 will survive the termination of this Foundry Capacity Agreement, and the exclusions and limitations of liability and of remedies shall apply notwithstanding any claim of a failure of any one or more remedies to accomplish their purpose. THE PARTIES EXPRESSLY WAIVE AND RELINQUISH ANY CONTRARY RIGHTS WITH RESPECT TO THE SUBJECT MATTER OF THIS SECTION 5 UNDER ANY APPLICABLE LAW, DECISION, AND/OR CUSTOM OR PRACTICE. 5.7 Upon written request from a Venturer and subject to satisfactory arrangements for payment to FabVen for the reasonable cost involved, FabVen will perform failure analysis of Products returned to FabVen pursuant to its standard return material authorization procedures. If such analysis shows the existence of material defects in breach of FabVen's warranties under this Foundry Capacity Agreement, FabVen will not be entitled to payment for the cost of the failure analysis concerning such defects for the specific Products which were subject to them. 5.8 If a Venturer requests FabVen to stop shipment of any Products which the Venturer is obligated to purchase pursuant to this Foundry Capacity Agreement, and the Products are subsequently determined in good faith by FabVen to have been processed in accordance with the requirements of this Foundry Capacity Agreement, FabVen shall be entitled to full payment for completed wafers and, in addition, for its reasonable direct costs for up to * worth of work in progress. Under this Section 5.8, payment for completed wafers will be at the purchase order price, and payment for work in progress shall allow FabVen to recover all reasonable direct costs involved. All such payments will be paid in full within forty-five days of the date of FabVen's invoice for the amounts involved. 6 6. SHIPMENT AND TERMS OF PAYMENTS 6.1 Each Venturer guarantees the payment of any and all obligations accrued pursuant to purchase orders from such Venturer under this Foundry Capacity Agreement. Invoices for Products shall be paid at net forty-five (45) days after the end of the month of invoice date. Subject to contrary written agreement, invoices for Products delivered shall show the number of wafers and extended price in U.S. dollars. 6.2 FabVen shall deliver all Products to a freight forwarder in the R.O.C. as designated by the Venturer involved. Such delivery shall be F.O.B. (IncoTerms 1990) at FabVen's facility. 6.3 In the event that any payment under this Foundry Capacity Agreement becomes restricted for any reason, the party whose payment obligation is restricted agrees, at its own expense, to immediately take whatever steps or actions may be necessary to assure such payment. 7. REPRESENTATIONS AND WARRANTIES The Venturers and FabVen each represent and warrant that they have the right and power to enter into this Foundry Capacity Agreement, and adequate resources to fulfill their respective obligations hereunder. 8.

                    SECURITES AND EXCHANGE COMMISSION



                            FOUNDRY VENTURE AGREEMENT


   This Foundry Venture Agreement ("Foundry Venture Agreement") is entered into
as of August ___, 1995, by and between Lattice Semiconductor Corp., a
corporation with its headquarters in Oregon  ("Lattice") and United
Microelectronics Corporation, a corporation organized under the laws of the
Republic of China ("UMC").

   Lattice understands that UMC is in discussions with others who are
interested in participating in FabVen.  Lattice agrees that UMC may commit to
such others (collectively referred to in this Foundry Venture Agreement as
"OtherVen") in such amounts as UMC deems appropriate, subject to the commitments
made to Lattice hereunder, and provided further that each OtherVen must commit
in writing to comply with and be bound by this Foundry Venture Agreement as if
specifically named as a Venturer herein.  Notwithstanding such OtherVen, Lattice
will be fully bound by and is committed to the terms of  this Foundry Venture
Agreement.

   Lattice, OtherVen and UMC (collectively "the Venturers") agree:


1. PURPOSE AND FORMATION OF VENTURE

1.1      Subject to the Technology Transfer and License Agreement and the
Foundry Capacity Agreement referred to in paragraphs 3 and 5 below
(collectively, the "Venture Agreements"), the Venturers each commit to form and
invest in a corporation to be formed under the laws of the Republic of China
("R.O.C.") for purposes of engaging in the business of providing integrated
circuit foundry services, making and selling integrated circuits in wafer, die
and packaged form as generally described in the FabVen Business Plan referred to
in paragraph 1.4 below.

1.2     UMC will arrange the formalities of submission to the Administration of
the Science Based Industrial Park for approval of and then for incorporation of
the corporation contemplated under this Foundry Venture Agreement, using a name
mutually agreeable to the Venturers (for purposes of this Foundry Venture
Agreement, the corporation contemplated under this Foundry Venture Agreement
shall be referred to as "FabVen.").  All reasonable expenses, up to a maximum of
USD $10,000 (exclusive of fees to be paid to the government), incurred by UMC
pursuant to this paragraph 1.2 with respect to such incorporation shall be
subject to reimbursement  by FabVen if the FabVen shares contemplated under
Paragraph 4 are not issued to UMC as described below.

1.3     Subject to the terms of  the Venture Agreements, FabVen shall engage in
the business of foundry services, and develop and improve processing and
manufacturing techniques in order to improve its competitiveness in the foundry
area.

1.4      UMC will submit to the Science Based Industrial Park a written
business plan (the "FabVen Business Plan") for the operations and for the
capital structure and expenditures of


                                        1




FabVen; this FabVen Business Plan is subject to approval by the Administration
of the Science Based Industrial Park; and, subject to the conditions of
confidentiality in Paragraph 9.7 below, will be made available to the Venturers.
 As part of the FabVen Business Plan, the Venturers contemplate FabVen will
apply for "tax holiday" and/or other favorable tax treatment under R.O.C. law.


2. INITIAL OPERATIONS

2.1     The Venturers generally contemplate the Building and Construction
Schedule for FabVen as shown in Attachment A and the Production and Business
Schedule for FabVen as shown in Attachment B.

2.2     Under mutually agreeable written terms to be negotiated between UMC and
FabVen, FabVen shall lease from UMC the land generally described in Attachment
C, and commonly known as UMC's Module D, located at No. 3 Li-Hsin Road Science
Based Industrial Park, Hsin Chu City, Taiwan, R.O.C.

   (a)  The Venturers contemplate that except as agreed by them in writing, the
terms of this lease will be at the market rate which would be negotiated between
a lessor and lessee dealing with one another at arms length in the context of an
independent lease and not based on some other business relationship.

   (b)  Without limiting the foregoing, any and all services and supplies
(including without limitation power, water, gas and/or materials) will not be
part of such lease, and will be the subject of such terms as may be negotiated
by FabVen.

   (c)  The lease term for Module D will be for an initial period of five
years, and FabVen will have the right to extend the lease for up to two
additional five year periods under terms to be stated in the lease agreement.
FabVen will occupy the land for this Module as its principal place of business,
and will utilize this land for its production facility.

2.3     The Venturers shall each cooperate to build out this land as FabVen's
production facility as quickly and efficiently as commercially reasonable,
provided however that this Paragraph 2.3 shall not impose any obligation to
provide additional funding beyond that expressly required under this Foundry
Venture Agreement.


3. TECHNOLOGY TRANSFER AND MANAGERIAL SUPPORT

   Promptly after FabVen's formation, UMC and FabVen will enter into a mutually
agreeable Technology Transfer and License Agreement pursuant to which UMC will
transfer to FabVen for use in FabVen facilities the Licensed Process (as defined
in the Technology Transfer and License Agreement) and related manufacturing
know-how.  The execution of the Technology Transfer and License Agreement is an
essential aspect of the relationship contemplated under this Foundry Venture
Agreement.

   products which the transferring Venturer at the time of such transfer was
   selling, was designing (as reflected in contemporaneous documents) or was
   contemplating designing and selling (as demonstrated in its then written
   business plan(s)), and all future revisions and more highly integrated
   versions of such products.


                                        4




   (iv) if prior to the completion of a public offering of FabVen securities on
   a recognized securities exchange, any Venturer (or UMC Affiliate holding
   such shares) wishes and/or attempts to transfer its shares in FabVen (other
   than as allowed by Paragraph 4.1(f)(i) and/or 4.1(f)(ii)) pursuant to any
   Court or other order or law, or as a result of any nonconsensual action by
   any authority with jurisdiction, the shares involved will be subject to a
   right of first refusal as follows:

        (aa)        the other Venturers (the "eligible other Venturers") will
        have the right to purchase the shares involved at their then fair
        market value as determined by a mutually agreeable independent
        appraiser;

        (bb)   each such eligible other Venturer will have the right to purchase
        such shares on a pro rata basis as determined by the ratio of their
        respective shareholding percentages (which, absent any previously
        permitted transfers, would be as shown in the table in Paragraph 4.1(b)
        above);

        (cc)   if any such eligible other Venturer elects not to exercise any
        portion or all of such right of first refusal within 30 days of the
        independent appraisal, such portion of such right of first refusal will
        be subject to exercise by the other eligible other Venturer, and the
        shares involved will be subject to a right of such other eligible other
        Venturer to purchase on the same terms as outlined above; and

        (dd)   if the other eligible other Venturer does not commit to purchase
        such shares within 60 days of the independent appraisal, all rights
        under this Paragraph 4.1(f)(iv) will expire as to such unpurchased
        shares.

     (g)  Subject to the requirements of and to the extent permissible under
R.O.C. law, to the extent that FabVen wishes to offer any equity beyond the USD
$600 million referred to in Paragraph 4.1(a) above, each Venturer shall have the
right of first refusal to participate in such offering in proportion to its then
current respective shareholding.

4.2  The parties shall in good faith after execution of this Foundry Venture
Agreement enter into negotiations regarding audit and information rights to be
provided to the Venturers, in order to, among other things, make timely public
disclosure of information about FabVen's profits, losses, and/or other financial
information reasonably required, in the view of such Venturer's counsel and
accountants, to be disclosed separately, in conjunction with, or consolidated
into, such Venturer's public quarterly, annual and/or other reports. Such rights
shall at a minimum be sufficient for such Venturers to timely comply with their
public reporting obligations, but shall not require FabVen to pay for and/or
incur the expenses of such matters. In the event the parties do not reach
agreement on such rights by December 15, 1995, the extent of such rights will be
decided conclusively by Price Waterhouse & Co. (Taipei office) and a nationally
recognized independent accounting firm nominated by Lattice and OtherVen.  If
the aforesaid accounting firms fail to decide such rights by January 30, 1996,
the matter shall be resolved by binding arbitration on an expedited basis.

forty-five day period following the written demand to meet to resolve the
dispute pursuant to Paragraph 7.1 above, and/or (ii) at such earlier time as any
Party involved repudiates and/or refuses to continue with its obligations to
negotiate in good faith.

7.3  The arbitration hearing will be before a panel of three neutral,
independent arbitrators.  The arbitration hearing will be conducted in the State
of Hawaii, and will be in the English language (with translations and
interpretations as reasonable for the presentation of evidence and/or conduct of
the arbitration).   Notwithstanding anything to the contrary, any party may
apply to any court of competent jurisdiction for interim injunctive relief as
may be allowed under applicable law with respect to irreparable harm which
cannot be avoided and/or compensated by such arbitration proceedings, without
breach of this Paragraph 7 and without any abridgment of the powers of the
arbitrators.

7.4  The arbitration will be conducted under the Rules of the Asia Pacific
Arbitration Center.  Notwithstanding anything to the contrary:


                                        7

promptly discuss and cooperate in good faith with respect to measures to
mitigate any harmful effect of such breach and with respect to possible
compensation to the injured party.

in the English language, which language shall be controlling in all respects,

interpreted and construed in all respects in accordance with the laws of the
State of California, provided however that all matters connected with the
purchase and formalities of stock and ownership interests in FabVen and the
Technology Transfer and License Agreement shall be interpreted and construed in
all respects in accordance with the laws of Taiwan, the Republic of China, all
without regard to that body of law which pertains to conflicts and/or choice of
law and excluding the UN Convention on Contracts for International Sales of
Goods.

9.10 If any provision of this Foundry Venture Agreement and/or the Venture
Agreements is held wholly or partially unenforceable for any reason, such
unenforceability shall not affect the enforceability of the remaining provisions
of such Agreements, and all provisions of such Agreements shall be construed so
as to preserve enforceability.

9.11 (a)  The terms and conditions contained in the FabVen Business Plan, this
Foundry Venture Agreement and/or the Venture Agreements and the documents
attached thereto (the "Plan and Agreements") shall supersede all previous
communications, understandings, representations and/or agreements, oral and/or
written, between the Venturers with respect to the subject matter hereof;

     (b)  There are no other such agreements, understandings and/or writings
except as stated above;

     (c)  No agreement or understanding varying, modifying or extending the
terms and/or conditions of such Plan and Agreements, nor any custom, practice,
course of dealing or conduct of the parties, shall be binding upon any Venturer
unless in writing and signed by a duly authorized officer or representative of
each Party to be bound; provided however that a Venturer and FabVen may agree to
ordering procedures which are established by them pursuant to mutual agreement;
and

     (d)  Except as expressly allowed under this Foundry Venture Agreement, no
party may transfer or assign its rights or delegate its duties under this
Agreement, except with the written consent of all the Parties to the agreement
involved.

9.12 No licenses, other than the licenses expressly granted under these
Agreements, are granted under these Agreements, by implication, estoppel or
otherwise.  Nothing in these Agreements shall be construed as conferring any
license, right to use or other right with respect to any trademark or trade name
of any party.  Each party may make reasonable reference by name to any other
party provided that the written consent of that other has been obtained in
advance.


9.13 (a)  The failure of any party  to enforce, or the delay by any party in
enforcing any of its rights under these Agreements shall not be deemed a waiver
or a containing waiver of such rights or a modification of these Agreements, and
such party may, within the time provided by applicable law, commence appropriate
proceedings to enforce any and/or all such rights.


                                       13




     (b)  The section headings in these Agreements are for convenience only and
do not define or limit nor will they be used to construe the content of such
sections.

     (c)  Each party expressly represents and warrants that it is free to enter
into these Agreements and that such party has not made and will not make any
creations or commitments in conflict with the provisions of these Agreements, or
which reasonably might interfere with the full and complete performance of such
party's obligations under these Agreements.  Each party further represents and
warrants that these Agreements, and the performance of its respective
obligations under these Agreements, and the consummation of the transactions
contemplated under these Agreements have been duly authorized and approved by
all necessary action, and all necessary consents or permits have been obtained,
and neither the execution of these Agreements nor the performance of the party's
respective obligations under these agreements will violate any term or provision
of any valid contract or agreement to which such party is subject and/or by
which such party is bound.  No further actions or consents are necessary to make
these Agreements valid binding contracts, enforceable against the respective
parties in accordance with their terms.

9.14  Nothing in this Foundry Venture Agreement and/or in the Venture Agreements
shall be deemed to create a general or limited partnership or an agency
relationship between the Venturers and/or FabVen, and the Venturers and FabVen
are independent companies.  The Venturers intend to become shareholders of
FabVen and thereafter purchase products manufactured from FabVen in an arm's
length vendor-purchaser relationship, and, in the case of FabVen and UMC, in an
arm's length vendor-purchaser, lessor-lessee, and licensor-licensee
relationship.  No party shall be entitled to act on behalf of and/or to bind any
one or more of the others.

9.15 The Venturers will cause FabVen to execute promptly after its formation the
Foundry Capacity Agreement, Technology Transfer and License Agreement, and this
Foundry Venture Agreement, to confirm FabVen's agreement to abide by the terms
in such agreements which are binding upon FabVen.


IN WITNESS WHEREOF, the Venturers have caused this Foundry Venture Agreement to
