far as such powers and privileges are necessary or convenient to the conduct,
promotion or attainment of the business, purposes or activities of the Company
as set forth in Section 2.6.1.

         2.7      TERM OF THE COMPANY. The Company was established and commenced
on the Effective Date. The Company shall dissolve on the Dissolution Date.
Notwithstanding the foregoing, the Company may be dissolved prior to the
Dissolution Date as provided in this Agreement or pursuant to the Act.

         2.8      INITIAL MEMBERS; STATUS OF MEMBERS.

                  2.8.1    INITIAL MEMBERS. The Initial Members shall be those
Persons listed as Members on Exhibit A.

                  2.8.2    STATUS OF MEMBERS. The Initial Members and any
additional or substituted Members shall be "members" of the Company, as that
term is used in the Act, subject to the terms and provisions of this Agreement.
The Managing Members shall have authority as specified herein.

         2.9      LIABILITY OF MEMBERS. No Member shall be obligated personally
for any debt, obligation or liability of the Company, whether arising in
contract, tort or otherwise, solely by reason of being a Member.

         2.10     COMPETITION; CONFLICT OF INTEREST.

                  2.10.1   MEMBER COMPETITION. Subject to the provisions of the
Confidentiality Agreements, and except as hereinafter provided, any Member may
engage in, acquire or possess an interest or interests in other business
ventures of any nature or description, independently or with others and neither
the Company nor any Member shall have any rights in or to such independent
ventures or the income or profits derived therefrom. Notwithstanding the
foregoing, each Member acknowledges, understands and agrees that pursuant to
Section 3.1.1, TSMC has contributed to the Company proprietary, trade secret,
know-how and other Confidential Information and that TSMC would not have entered
into this Agreement with a Prohibited Person. Further, each Member acknowledges,
understands and agrees that monetary compensation would not be an adequate
inducement for TSMC to enter into this Agreement with a Prohibited Person.
Accordingly, each Member except TSMC agrees that so long as such Member shall be
a Member and for a period of two years thereafter, such Member shall not acquire
or possess a controlling interest, directly or indirectly, by operation of law
or otherwise, in any venture (an "Other Venture") (not including TSMC or an
Affiliate thereof) that has as one of its primary purposes the provision of
foundry services for the manufacture of IC wafers for sale to third parties not
affiliated with such Other Venture and not for the Member's own use or the use
of other parties affiliated with the Other Venture. This restriction shall not
limit the existing ventures of any Member, or future ventures in which any
Member has a non-controlling minority interest, from selling IC wafers to third
parties not affiliated with such Other Venture. This Section shall not limit the
ability of TSMC or any of its Affiliates to enter into any Other Venture or
subject to Section 13.2, to construct any other foundry.

                  2.10.2   CONFLICT OF INTEREST. Subject to Section 3.5, the
fact that a Person is employed by or is directly or indirectly interested in or
connected with any Person


                                                            AMENDED AND RESTATED

employed by the Company to render any service or from whom the Company may buy
merchandise shall not prohibit the Company from employing or dealing with such
Person; provided, however, that any contract, employment or other arrangement
with such Person shall be on an arm's-length basis and in accordance with
competitive rates and other terms prevailing throughout the industry for similar
goods or services.

         2.11     BUSINESS PLAN. On the Effective Date each Member received a
preliminary annual operating budget and business plan of the Company for Fiscal
Years 1996 through 2002, which was prepared by TSMC and its Affiliates in good
faith for planning purposes and is incorporated herein by this reference (as it
may be amended from time to time, the "Business Plan"). Each Managing Member
agrees to use reasonable commercial efforts in accordance with the terms of this
Agreement to facilitate the implementation of the Business Plan by the Company.
Notwithstanding the foregoing, the Members acknowledge that the Business Plan is
a projection only and, as a forward looking statement, reflects certain
anticipated goals, which may not be realized. The Members further acknowledge
that the Business Plan does not constitute an assurance, representation,
warranty or agreement by any Member or the Company for any purpose, including
but not limited to, the purpose of determining whether to enter into this
Agreement. Any material change or amendment to the Business Plan shall require
the approval of Members holding not less than 71% in Percentage Interest, as
provided in Section 6.4.2.

         2.12     MEMBER INTELLECTUAL PROPERTY.

                  2.12.1   GRANT OF LICENSES. Each Member, including TSMC and
its Affiliates to the extent not provided for pursuant to the Technology License
and Assistance Agreement or the Advanced Process Agreement, shall grant or
extend to the Company the rights, licenses or cross licenses from third parties
obtained or held by such Member as the same are related to and required for the
manufacture of IC wafers by the Company, to the extent that any such action is
not in conflict with such Member's agreements with third parties. In case any
third party agreement requires the payment of fees or royalties to a third party
in the event of such grant or extension, the Company shall be offered the option
to accept the grant or extension and to pay such fees or royalties.

                  2.12.2   SHARING OF TECHNOLOGY. Any Managing Member (other
than TSMC or its Affiliates, to which the terms of the Technology License and
Assistance Agreement and Advanced Process License Agreement will apply), which
has knowledge or know-how relating to the manufacture of IC wafers may offer to
provide such knowledge or know-how to the Company in consideration for the right
to use the knowledge or know-how developed by the Company relating to that
knowledge or know-how provided by such Member. The terms and conditions of any
such exchange of knowledge or know-how shall be determined by mutual agreement
between the applicable Managing Member and the Company. Notwithstanding the
foregoing, any such Managing Member (other than TSMC or its Affiliates)
shall not use the knowledge or know-how developed by the Company to manufacture
any products competitive with the Products produced for any other Managing
Member (other than TSMC or its Affiliates).

                                                            AMENDED AND RESTATED

   20
                  2.12.3   CO-DEVELOPMENTS. In the event personnel of the
Company and any Managing Member co-develop (i.e. both parties substantially and
significantly contribute to the development) devices, ICs, processes or
apparatus relating to the subject matter of this Agreement, the Manufacturing
Agreement, the Purchase Agreement, or the Future Purchase Agreement, then the
Intellectual Property Rights created by such co-development shall be jointly
owned by the Company and the applicable Managing Member without accounting to
each other, both parties having the right under the Intellectual Property Rights
obtained with respect to such co- development to make, have made, use, modify,
lease, sell, or otherwise dispose of products and to license (with a right to
sub-license) such Intellectual Property Rights, subject to the other party's
rights therein but without the necessity of obtaining the consent of the other
party. The Company and applicable Managing Member shall cooperate in applying
for, prosecuting and maintaining patents and copyright and mask work
registrations for such co-developments and shall equally divide the expenses
thereof. Notwithstanding the preceding sentence, either the Company or the
applicable Managing Member may elect not to share the expenses of any such
applications in any or all countries, in which case the other party may file
and/or prosecute at its own expense and shall have sole control and ownership of
such applications and any patents, copyright or mask work registrations issuing
thereon, subject to a non-exclusive non- transferrable, paid-up and
royalty-free, worldwide license under such patents, copyright and mask right
registrations in favor of the non-electing party to make, have made, use,
modify, lease, sell, or otherwise dispose of products to the extent of the
rights granted by such patents and registrations (with the right to sublicense
only to Affiliates). The Company or the applicable Managing Member, as the case
may be, shall be obligated to share the expenses referred to in the preceding
sentence unless such party provides written notice of its election not to do so
to the other party within thirty (30) days of a written request from such other
party. An election not to share expenses shall be irrevocable.

         2.13     FORMATION AUTHORIZATION. Each of the Members ratifies and
approves the acts of TSMC prior to the date of this Agreement taken to (i)
handle matters with respect to the formation and establishment of the Company,
(ii) commit to the acquisition of the Real Property including the grant of the
TSMC Land Option, (iii) commit to the construction of the Foundry, and (iv)
commit to the purchase of such equipment as is required by the Company to
commence the Project (collectively, the "Organizational Matters"). Each Member
authorizes TSMC to continue to implement the Organizational Matters in
accordance with this Agreement. TSMC will attempt to obtain favorable terms for
such Organizational Matters, and the Members will cooperate to discuss and
resolve any issues in connection therewith.

         2.14     REIMBURSEMENT OF TSMC EXPENSES. By execution and delivery of
this Agreement, the Members agree that the following out-of-pocket expenses
incurred by TSMC, or its Affiliates, upon presentation by TSMC to the Company of
an itemization of such expenses, shall be reimbursed by the Company. Such
expenses may include the following:

                  2.14.1   Any and all reasonable expenses incurred for the
acquisition of the Real Property including but not limited to those incurred in
the site selection and permitting activities;

                  2.14.3   Any and all fees and expenses charged by the counsel,
consultants and specialists retained in connection with the formation of the
Company, the acquisition of the Real Property and the construction of the
Foundry; and

                  2.14.4   Any and all other fees and expenses incurred in
handling the matters authorized in Section 2.13 or this Section 2.14.

An estimate of such expenses as of the Effective Date was delivered to each
Member on the Effective Date.

                              CAPITAL CONTRIBUTIONS

         3.1      INITIAL CAPITAL CONTRIBUTIONS.

                  3.1.1    FIRST PART CAPITAL CONTRIBUTION. Subject to the
satisfaction or waiver of the conditions precedent set forth in Article 17, on
the Effective Date (sometimes referred to herein as the "First Contribution
Date") each Initial Member contributed to the Company in good same day funds an
amount of cash equal to the cash contribution set forth opposite such Initial
Member's name on Exhibit A under the column "First Part Capital Contribution"
and in addition TSMC contributed to the Company (i) the Manufacturing Agreement,
the Technology License and Assistance Agreement and the Advanced Process
Agreement, by assigning such agreements to the Company, and (ii) all rights and
interests of TSMC in the Real Property, the Foundry and all equipment purchased
by TSMC ("First Part Capital Contribution").

                  3.1.2    SECOND PART CAPITAL CONTRIBUTION. On November 30,
1996 (the "Second Contribution Date"), each Initial Member shall contribute to
the Company an amount of cash equal to the cash contribution set forth opposite
such Initial Member's name on Exhibit A under the column "Second Part Capital
Contribution" (the "Second Part Capital Contribution").

                  3.1.3    THIRD PART CAPITAL CONTRIBUTION. On November 3, 1997
(the "Third Contribution Date"), each Initial Member shall contribute to the
Company an amount of cash equal to the cash contribution set forth opposite such
Initial Member's name on Exhibit A under the column "Third Part Capital

                  3.1.4    PERCENTAGE INTEREST. Upon making each such Capital
Contribution, each Initial Member shall be credited for its Capital Contribution
and shall have the Percentage Interest in the Company as set forth with respect
to such Initial Member on Exhibit A.

                                                            AMENDED AND RESTATED

         3.2      ADDITIONAL CAPITAL CONTRIBUTION. No Member shall be obligated
to or shall make any additional capital contribution to the Company in excess of
such Member's portion of the Initial Capital Contribution provided for in
Section 3.1 ("Additional Capital Contribution") except with the approval of the
Board of Directors. The Board of Directors shall send to each Member written
notice of the Additional Capital Contribution including a description of the
purpose of the Additional Capital Contribution, a statement of the potential
benefits to the Company and to Members who make such Additional Capital
Contribution and a statement of the potential impact upon each Member pursuant
to Section 3.3.1 if such Member does not make the Additional Capital
Contribution (the "Additional Capital Contribution Notice"). If a proposed
Additional Capital Contribution, together with all prior Additional Capital
Contributions, exceeds in the aggregate an amount equal to 15% of the Total
Initial Capital Contribution, as set forth on Exhibit A hereto, such Additional
Capital Contribution must also be approved by the Members holding not less than
71% in Percentage Interest as provided in Section 6.4.2. Following approval as
set forth above and subject to Section 3.3.2.1, each Member shall contribute its
Additional Capital Contributions to the Company in proportion to its Percentage
Interest promptly at such time or times as may be so established by the Board of
Directors for the payment thereof.

         3.3      CONSEQUENCES OF FAILURE TO CONTRIBUTE.

                  3.3.1    DEFAULT ON SECOND PART OR THIRD PART CAPITAL
CONTRIBUTION. In the event a Member fails to pay its Second Part Capital
Contribution or its Third Part Capital Contribution as contemplated in this
Agreement, such Defaulting Member shall pay to the Non-Defaulting Members which
have made their required Second Part Capital Contributions or Third Part Capital
Contributions, as the case may be, as a partial liquidated payment for damages
suffered by the Company and the Non-Defaulting Members as a result of such
failure to pay, a cash payment equal to 10% of the Second Part Capital
Contribution or Third Part Capital Contribution, as the case may be, of the
Defaulting Member. Such cash payment shall be distributed among the
Non-Defaulting Members according to their respective Percentage Interests. The
Defaulting Member's Membership Interest thereupon and without more shall be
terminated and the following procedures shall apply:

                          3.3.1.1  MISSING CAPITAL CONTRIBUTION. The
Non-Defaulting Members shall have the right, but not the obligation to, subject
to the provisions of Section 8.6, contribute that portion of the Capital
Contribution to have been funded by the Defaulting Member ("Missing Capital")
according to each electing Non-Defaulting Member's Percentage Interest. If any
Non-Defaulting Member elects to contribute none or less than all of such
Non-Defaulting Member's pro rata share of the Missing Capital, then the other
Non-Defaulting Members may elect to contribute the remaining portion of the
Missing Capital in proportion to their respective Percentage Interests. If less
than all of the Missing Capital is contributed by Non-Defaulting Members,
subject to the provisions of Section 8.6, one or more new Members, if approved
pursuant to Section 8.4, may be admitted as a Member or Members to contribute
any remaining Missing Capital to the Company. If the entire Missing Capital is
not contributed, the Initial Capitalization of the Company shall be reduced
accordingly. Following such process, the Percentage Interest of all Members
shall, subject to the last sentence of Section 3.3.1.4, be
                                                            AMENDED AND RESTATED
                                             LIMITED LIABILITY COMPANY AGREEMENT
                                       15

adjusted so that each Member's Percentage Interest (including that of any new
Member) shall be a fraction, the numerator of which is the aggregate amount of
each Member's Capital Contributions and the denominator of which is the sum of
all Member's Capital Contributions (including that of any new Member) and each
Member's Capital Account Balance shall be adjusted accordingly. As used in the
preceding sentence, Capital Contributions shall include those portions of
Capital Contributions made by a Defaulting Member or a Terminated Member that
are credited to the Capital Account Balances of Non-Defaulting Members or
Remaining Members following a transfer of part of the Defaulting Member's
Interest or Terminated Member's Interest under clause (ii) of either of Section
3.3.1.4 or Section 10.5.

                  3.3.1.2  PURCHASE RIGHT. Upon termination of a Defaulting
Member's Membership Interest pursuant to this Section and after giving effect to
Section 3.3.1.1, subject to the provisions of Section 8.6, the Non-Defaulting
Members shall have the right to purchase and the Defaulting Member shall have
the obligation to sell, the Defaulting Member's Interest in the Company in the
manner contemplated in Sections 3.3.1.3 through 3.3.1.6, inclusive. The purchase
price for such Interest shall be an amount equal to 50% of the cash Capital
Contributions of the Defaulting Member as of the termination date of the
Defaulting Member. Such reduction in value shall constitute partial compensation
for damages suffered by the Company and the Non-Defaulting Members as a result
of the failure by the Defaulting Member to contribute the Second Capital
Contribution or Third Capital Contribution, as the case may be. The Board of
Directors shall give notice to all Non-Defaulting Members of such purchase
price.

                  3.3.1.3  OPTION OF NON-DEFAULTING MEMBERS TO PURCHASE. Each
Non-Defaulting Member shall have the right, but not the obligation, to elect to
purchase a portion of the Defaulting Member's Interest, as hereinafter provided.
Any Non-Defaulting Member so electing shall notify the Directors in writing
within thirty (30) days after the notice from the Directors referred to in
Section 3.3.1.2 above, of such Non- Defaulting Member's desire to purchase a
portion of the Defaulting Member's Interest. The failure of any Non-Defaulting
Member to submit such notice within the applicable period shall constitute an
election on the part of the Non-Defaulting Member not to purchase any of the
Defaulting Member's Interest. Each Non-Defaulting Member so electing to purchase
shall be entitled to purchase a portion of the Defaulting Member's Interest in
the same proportion that the Percentage Interest of the Non-Defaulting Member
bears to the aggregate of the Percentage Interest of all of the Non-Defaulting
Members electing to purchase a portion of the Defaulting Member's Interest.

                  3.3.1.4  ELECTION TO PURCHASE LESS THAN ALL OF THE DEFAULTING
MEMBER'S INTEREST. If any Non-Defaulting Member elects to purchase none or less
than all of such Non-Defaulting Member's pro rata share of the remaining
Defaulting Member's Interest, then subject to the provisions of Section 8.6, the
other Non-Defaulting Members may elect to purchase that Interest remaining in
proportion to their respective Percentage Interests. Each Non-Defaulting Member
who purchases part of the Defaulting Member's Interest shall succeed to a pro
rata share of the Defaulting Member's Capital Account Balance. If the
Non-Defaulting Members do not purchase the entire Interest of the Defaulting
Member, then subject to the provisions of Section 8.6, one or more new Members,
if approved pursuant to Section 8.4, may be admitted as a Member and purchase
the remaining Defaulting Member's Interest by paying for such Interest in 

                                                            AMENDED AND RESTATED

cash. If the entire remaining Interest has not been purchased, with respect to
all or any remaining share of the Defaulting Member's Interest, the Defaulting
Member shall have only an Economic Interest, and without limiting the generality
of the foregoing, shall not be a Managing Member, shall not be entitled to
designate a Director hereunder and any current Director or Directors appointed
by such Member shall be deemed to be removed and the number of Directors on the
Board of Directors shall be reduced accordingly. In such event, as partial
compensation for damages suffered by the Company and the Non-Defaulting Members,
(i) the Defaulting Member's remaining Interest shall be reduced by fifty percent
(50%) and the Non-Defaulting Members' Interests shall be increased pro rata
accordingly, (ii) the Defaulting Member's Capital Account Balance shall be
reduced by 50%, and the difference shall be added to the Capital Account
Balances of the Non-Defaulting Members, pro rata according to their Interests,
and (iii) solely for purposes of determining the Managing Members' and a
Defaulting Member's rights and obligations to purchase the output of the Foundry
under the Purchase Agreement or Future Purchase Agreement (which rights and
obligations shall be a function, to be specified in each of those agreements, of
the Managing Members' and Defaulting Member's Percentage Interests), effect
shall not be given to any increase or decrease in a Managing Member's or
Defaulting Member's Percentage Interest attributable to (A) the operation of
clause (i), or (B) any reduction (x) in the Capital Contribution of the
Defaulting Member due to (I) that portion of the Missing Capital that is not
contributed by any other Person or (II) that portion of the Missing Capital
contributed by a Person other than a Managing Member or a new Member who will
become a party to the Purchase Agreement or Future Purchase Agreement (a "New
Buyer") or (y) in the total Capital Contributions of Members due to that portion
of the Missing Capital that is not contributed by any Person.

                  3.3.1.5  PAYMENT OF PURCHASE PRICE. The purchase price shall
be paid by the electing Non-Defaulting Members by either of the following
methods, each of which may be selected separately by the electing Non-Defaulting
Members in their respective sole discretion:

                  (I)      The Non-Defaulting Members shall at the consummation
of the purchase of the Defaulting Member's Interest ("Closing") pay in cash the
total purchase price for the Defaulting Member's Interest; or

                  (II)     The Non-Defaulting Members shall pay at the Closing
one-fifth (1/5) of the purchase price in cash and the balance of the purchase
price shall be paid in four equal annual principal installments, plus accrued
interest, and be payable each year on the anniversary date of the Closing. The
unpaid principal balance shall accrue interest at the current applicable U.S.
Federal rate as provided in the Code for the month in which the initial payment
is made, but the Non-Defaulting Members shall have the right to prepay in full
or in part at any time without penalty. The obligation of each purchasing
Non-Defaulting Member to pay its portion of the balance due shall be evidenced
by a separate promissory note executed by the respective Non-Defaulting Member.
Each such promissory note shall be in an original principal amount equal to the
portion owed by the respective purchasing Non-Defaulting Member. The promissory
note executed by each purchasing Non-Defaulting Member shall be secured by a
pledge of that portion of the Defaulting Member's Interest purchased by such
Non-Defaulting Member.

                                                            AMENDED AND RESTATED
                                             LIMITED LIABILITY COMPANY AGREEMENT

   25
                           3.3.1.6  CLOSING OF PURCHASE OF DEFAULTING MEMBER'S
INTEREST. The Closing for the sale of a Defaulting Member's Interest pursuant to
this Section 3.3 shall be held at 10:00 a.m. at the principal office of Company
no later than sixty (60) days after the determination of the purchase price. At
the Closing, the Defaulting Member or such Defaulting Member's legal
representative shall deliver to the electing Non-Defaulting Members an
instrument of transfer (containing warranties of title and no encumbrances)
conveying the Defaulting Member's Interest free and clear of all liens, charges
and encumbrances whatsoever, except as permitted by the purchaser thereof. The
Defaulting Member or such Defaulting Member's legal representative, the Company
and the Non-Defaulting Members shall do all things and execute and deliver all
documents as may be necessary or convenient to consummate such sale and purchase
in accordance with the terms and provisions of this Agreement. Without limiting
the generality of the foregoing, each Defaulting Member hereby appoints each
Non-Defaulting Member as its attorney-in-fact and agent, with full power and
authority to take all actions and execute and deliver all agreements, deeds,
leases, releases, assignments, bills of sale, security instruments and any other
document which, in the sole judgment of such Non-Defaulting Member, is necessary
or convenient to consummate such sale and purchase.

                  3.3.2    FAILURE TO PAY ADDITIONAL CAPITAL CONTRIBUTION.

                           3.3.2.1  FAILURE TO PAY ADDITIONAL CAPITAL CALL NOT
APPROVED BY NON-PAYING MEMBER. The provisions of this Section 3.3.2.1 shall
apply in the event a Member fails to make an Additional Capital Contribution:
(i) requiring the consent of Members holding not less than 71% in Percentage
Interest as provided in Section 6.4.2.5, if such non-paying Member did not
consent to such Additional Capital Contribution, or (ii) not requiring the
consent of Members pursuant to Section 6.4.2.5 and: (x) not approved by such
Member's representative on the Board of Directors if such Member has a
representative on the Board of Directors, or (y) if such Member does not have a
representative on the Board of Directors. Such a Member shall be referred to in
this Section as a "Non-Paying Member." In such event, the other Members who have
made the Additional Capital Contribution (the "Paying Members") shall have the
right, but not the obligation, subject to the provisions of Section 8.6, to
contribute that portion of the Additional Capital Contribution to have been
funded by the Non-Paying Member ("Missing Additional Capital") according to each
electing Paying Member's Percentage Interest. If any Paying Member elects to
contribute none, or less than all of such Paying Member's pro-rata share of the
Missing Additional Capital, then the other Paying Members may elect to
contribute the remaining portion in proportion to their respective Percentage
Interests. If less than all of the Missing Additional Capital is contributed by
the Paying Members, one or more new investors, approved as provided in Section
8.4, may be admitted as a Member to pay to the Company the remaining Missing
Additional Capital. The failure of the Non-Paying Member to make an Additional
Capital Contribution under the circumstances specified in this Section shall not
constitute an Event of Default under this Agreement, but the Percentage
Interests of all Members shall be adjusted so that each Member's Percentage
Interest (including that of the new Member, if any), shall be a fraction, the
numerator of which is the aggregate amount of each Member's Capital
Contributions and the denominator of which is the sum of all Members' Capital
Contributions (including that of the new Member, if any). As used in the
preceding sentence, Capital Contributions shall include those portions of
Capital Contributions made by a Defaulting Member or a Terminated Member that
are credited to the Capital Account Balances of Non-

                                                            AMENDED AND RESTATED

Defaulting Members or Remaining Members following a transfer of part of the
Defaulting Member's or Terminated Member's Interest to such Members under clause
(ii) of either of Section 3.3.1.4 or Section 10.5. Notwithstanding the
foregoing, if the Board of Directors in its reasonable discretion determines
that the fair market value of the Company as of the date immediately prior to
the requested Additional Capital Contribution is less than total Capital
Contributions made to such date, the Members' Percentage Interests (including
that of the new Member, if any), shall be adjusted to reflect a fraction, the
numerator of which is (A) the fair market value of the Company multiplied by the
Percentage Interest of each Member as of such date, plus (B) the Additional
Capital Contribution made by such Member (if any), and the denominator of which
is such fair market value of the Company as of such date plus the total
Additional Capital Contributions of all Members (including that of the new
Member, if any). The Board of Directors in its reasonable discretion shall
determine the fair market value of the Company except that any Director who was
elected by a Non-Paying Member shall not vote or otherwise participate in any
such determination. Each Member's Capital Account shall be adjusted as provided
in Section 3.4. If the failure to make the Additional Capital Contribution is a
Dilution Event, each Managing Member's right to receive and obligation to take
the output of the Foundry pursuant to the Purchase Agreement and the Future
Purchase Agreement shall be adjusted contemporaneously to give effect to the
changes in Members' Percentage Interests. If the failure to make the Additional
Capital Contribution is not a Dilution Event each Managing Member's right to
receive and obligation to take the output of the Foundry pursuant to the
Purchase Agreement and Future Purchase Agreement shall not be affected in which
case the provisions of Section 8.6 with respect to an increase in the
obligations of new Members or Members acquiring an additional Percentage
Interest pursuant to such agreements shall not apply. Additionally, a Non-Paying
Member shall not be entitled to acquire directly or indirectly any Products of
the Company, the production of which has been funded, enabled or otherwise
facilitated by such Additional Capital Contribution made by the Paying Members,
and the production of which was described in the Additional Capital Contribution
Notice.

                           3.3.2.2  DEFAULT FOLLOWING MEMBERS APPROVAL OF
ADDITIONAL CAPITAL CONTRIBUTION. This Section 3.3.2.2 shall apply in the event a
Member fails to make an Additional Capital Contribution or any installment
payment of an Additional Capital Contribution that has been: (i) approved by
such Defaulting Member, if the Additional Capital Contribution is one requiring
approval of Members holding not less than 71% in Percentage Interest as provided
in Section 6.4.2.5, or (ii) approved by such Member's representative on the
Board of Directors (if such Defaulting Member has a representative on the Board
of Directors) if the Additional Capital Contribution is not one requiring
approval of Members holding not less than 71% in Percentage Interest as provided
in Section 6.4.2.5. In either circumstance, the Defaulting Member's Membership
Interest shall be terminated and the procedures set forth in Sections 3.3.1.1
through 3.3.1.6 inclusive, shall apply.

         3.4      CAPITAL ACCOUNTS. The Capital Accounts of the Members shall be
determined and maintained throughout the full term of the Company in accordance
with the capital account rules of Section 1.704-1(b)(2)(iv) of the Section
704(b) Regulations (relating to maintenance of capital accounts).

                                                            AMENDED AND RESTATED

   27
                  3.4.1    Each Member shall have a capital account ("Capital
Account") which shall be credited (increased) by:

                           3.4.1.1  the amount of such Member's cash capital
contributions to the Company and the agreed net fair market value of property
other than cash contributed to the Company by such Member (net of liabilities
secured by such contributed property that the Company is considered to have
assumed or taken subject to for purposes of Section 752 of the Code);

                           3.4.1.2  the amount of Net Profits and items thereof
allocated to it pursuant to Article 5 hereof; and

                           3.4.1.3  any other increase required to be made to
the Capital Account of the Member by the Section 704(b) Regulations, to the
extent not otherwise provided for herein.

                  3.4.2    Each Member's Capital Account shall be debited
(decreased) by:

                           3.4.2.1  the amount of Net Losses and items thereof
allocated to such Member pursuant to Article 5 hereof;

                           3.4.2.2  all amounts paid, distributed or deemed
distributed to it pursuant to Article 4 hereof, and the fair market value of
property distributed to it (in each case, net of liabilities securing such
distributed property that such Member is considered to have assumed or taken
subject to under Section 752 of the Code); and

                           3.4.2.3  any other reductions in the Capital Account
of the Member required by the Section 704(b) Regulations, to the extent not
otherwise provided for herein.

                  3.4.3    In the discretion of the Board of Directors, the
capital accounts may be adjusted to reflect a revaluation of Company property to
the extent permitted by the Section 704(b) Regulations in connection with
capital contributions to the Company by new or existing Members resulting in a
change of Percentage Interests held by the Members, or in connection with
distributions by the Company to a retiring or continuing Member as consideration
for an Interest in the Company.

         3.5      TRANSACTIONS BETWEEN MEMBERS AND THE COMPANY;
COMPANY LOANS AND GUARANTEES.

                  3.5.1 TRANSACTIONS BETWEEN MEMBERS AND THE COMPANY. With the
written approval of the Board of Directors, and the written consent of Members
with no economic interest in the transaction in question ("Disinterested
Members") holding a majority of the Percentage Interests of Disinterested
Members, a Member or an Affiliate of a Member may transact business or contract
with the Company so long as the terms of any such transaction are at fair market
value and are comparable to those that could be obtained between independent
parties negotiating at arm's-length. The representatives of the contracting
Member on the Board of

                                                            AMENDED AND RESTATED
                                             LIMITED LIABILITY COMPANY AGREEMENT
                                       20
   28
Directors shall not be prohibited from participating in the decision made to
enter into any such transaction. All Members agree that the terms of the
Ancillary Agreements and the Executive Incentive Plan satisfy the standard set
forth in this Section 3.5.1, that such documents are deemed to have been
approved by the Board of Directors and the Members and that no further action or
approval by the Board of Directors or the Members to approve such instruments or
transactions is required.

         3.5.2    LOANS TO THE COMPANY. With the approval of the Board of
Directors, and the consent of the Members contemplated in Section 6.4.2, a
Member may lend money to, act as a surety, guarantor or endorser for, or
guarantee or assume one or more specific obligations of, or provide collateral
for the Company (collectively, "Company Loans"), and, subject to applicable law,
has the same rights and obligations with respect to any Company Loan as a Person
who is not a Member; provided, however, that each Managing Member shall have the
option to participate in any such Company Loan pro rata in accordance with such
Managing Member's Percentage Interest. Unless otherwise agreed to in writing by
the Board of Directors, Company Loans shall not be considered capital
contributions or be reflected in the balance of any Capital Account. Each
Company Loan shall be a debt due from the Company to the lending Member, shall
bear interest at the rate agreed to between such Member and the Company and,
except as otherwise expressly provided in this Agreement or agreed between such
Member and the Company at the time such funds are advanced, shall be repaid as
soon as practicable to such Member.

         3.5.3    PROHIBITION ON LOANS TO MEMBERS. The Company shall not lend
money to, act as a surety, guarantor or endorser for, or guaranty or assume any
obligations of any Member.

         3.5.4    GUARANTEES. To the extent a Member guarantee is required by an
institutional lender to the Company, the Board of Directors shall send to each
Member written notice of the required guarantee including a description of the
purpose of the loan the Members are being asked to guarantee, a statement of the
potential benefits of the loan to the Company and the Members who guarantee the
loan and a statement of the potential impact upon each Member pursuant to this
Section if such Member does not guarantee the loan (the "Guarantee Notice"). The
Members agree to provide, to a maximum aggregate amount of US $250 Million, a
several guarantee of the Company's debt according to their respective Percentage
Interests. If any Member fails to provide, in whole or in part, a guarantee as
specified above, such failure shall not constitute an Event of Default under
this Agreement, but the Percentage Interests of the Members shall be adjusted so
that each Member's Percentage Interest shall be a fraction, the numerator of
which represents the aggregate amount of each Member's Capital Contribution plus
any amount such Member guaranteed as provided for above, and the denominator of
which represents the sum of all Members' Capital Contributions plus the total
amount guaranteed by the Members. As used in the preceding sentence, Capital
Contributions shall include those portions of Capital Contributions made by a
Defaulting Member or Terminated Member that are credited to the Capital Account
Balances of Non-Defaulting Members or Remaining Members following a transfer of
part of the Defaulting Member's or Terminated Member's Interest to such Members
under clause (ii) of either of Section 3.3.1.4 or Section 10.5. If the failure
to guarantee the

   29
Company's debt is not a Dilution Event each Member's right to receive and
obligation to take the output of the Foundry pursuant to the Purchase Agreement
and Future Purchase Agreement shall not be affected. However, if such failure is
a Dilution Event, the Members' right to receive and obligation to take the
output of the Foundry pursuant to the Purchase Agreement and the Future Purchase
Agreement shall be adjusted contemporaneously to reflect the change in
Percentage Interests. Additionally, if a Member fails to provide a guarantee as
specified above, such Member shall not be entitled to acquire directly or
indirectly any Products of the Company, the production of which has been funded,
enabled or otherwise facilitated by the proceeds of any Company debt such Member
failed to guarantee, the production of which was described in the Guarantee
Notice.

         3.6      RIGHTS WITH RESPECT TO CAPITAL.

                  3.6.1    CAPITAL. No Member shall have the right to withdraw
all or any part of its Capital Contribution. No Member shall have any right to
the return of all or any part of its Capital Contribution except through
distributions as provided in this Agreement.

                  3.6.2    NO INTEREST ON CAPITAL CONTRIBUTIONS. Except as
expressly provided in this Agreement, no Capital Contribution of any Member
shall bear any interest or otherwise entitle the contributing Member to any
compensation for use of the contributed capital.

                  3.6.3    DISTRIBUTION IN KIND. Except as provided in Article
19, no Member shall have the right to demand and receive any distribution in any
form other than cash, regardless of the nature of its Capital Contribution. No
Member shall be compelled to accept a distribution of any asset in kind to the
extent that the percentage of the asset distributed to such Member exceeds a
percentage of that asset that is equal to the percentage in which such Member
shares in distributions from the Company.

                                    ARTICLE 4
                                  DISTRIBUTIONS

         4.1      CASH AVAILABLE FOR DISTRIBUTION. Cash Available for
Distribution shall be distributed to the Members pro rata in accordance with
each Member's Percentage Interest, in accordance with the following:

                  4.1.1    DETERMINATION. The Company shall distribute, from
time to time, as determined by the Board of Directors and approved by the
Members as provided in Section 6.4.2, Cash Available For Distribution, if any,
to the Members in accordance with their respective Percentage Interests.

                  4.1.2    DEFINITION OF CASH AVAILABLE FOR DISTRIBUTION. For
purposes of this Agreement, "Cash Available For Distribution" means the cash
available for distribution to Members after giving effect to the following: (i)
projected cash available from operations of the Company as determined by the
Board of Directors; (ii) cash on hand of the 

                                                            AMENDED AND RESTATED

   30
Company, (iii) a prudent level of reserves for the Company, as determined by the
Board of Directors; (iv) projected cash needed for operations of the Company
including for payment of debt and for future Special Tax Distributions to
Members, as such are determined by the Board of Directors, and (iv) the
anticipated total project costs for any new foundry to be developed by the
Company or retrofit of the Foundry which have been approved by the Members in
accordance with Section 6.4.2. 

                  4.1.3    FINAL SALE. Notwithstanding the foregoing provisions,
all distributions and proceeds resulting from a final sale or other event
causing a dissolution of the Company shall be applied in the manner set forth in
Section 11.4 and not in the manner set forth in this Section 4.1.

         4.2      TAX DISTRIBUTIONS. Notwithstanding anything in Section 4.1 to
the contrary, for each Fiscal Year, the Company shall distribute to its Members
in accordance with their respective Percentage Interest and to the extent
available from the cash resources of the Company (including borrowings), before
calculation of Cash Available for Distribution, within ninety (90) days after
the end of each Fiscal Year (a "Special Tax Distribution"), an aggregate amount
of cash equal to the excess of (i) the product of (A) the Company's aggregate
amount of Net Profit for the Fiscal Year determined for this purpose only
without regard to the adjustments set forth in clauses (iii) and (iv) of Section
1.1.47 and (B) the highest applicable composite marginal rate borne by any
Member for U.S. Federal, state and local taxes for such Fiscal Year over (ii)
the aggregate net cash distributions previously made to the Members with respect
to such Fiscal Year. All amounts withheld under Section 4.3 shall be deemed to
be distributions to the respective Members for purposes of this Section 4.2.

         4.3      AMOUNTS WITHHELD. All amounts withheld pursuant to the Code or
any provision of any state or local tax law with respect to any payment,
distribution or allocation to the Company or the Members shall be treated for
all purposes under this Agreement as amounts distributed to the Members pursuant
to this Article 4. The Board of Directors is authorized to withhold from
distributions, or with respect to allocations, to the Members and to pay over to
any U.S. Federal, state, or local government any amounts required to be so
withheld pursuant to the Code or any provisions of any other U.S. Federal, state
or local law and shall allocate such amounts to the Members with respect to
which such amount was withheld.

                        ALLOCATION OF PROFITS AND LOSSES

         5.1      ALLOCATION OF NET PROFIT AND LOSS. In each fiscal period Net
Profit and Net Loss of the Company shall be allocated among the Members as
follows:

                  5.1.1    First, Net Profit and Net Loss shall be allocated
among the Members in a manner to bring Capital Account balances of the Members
in proportion to their respective Percentage Interests as quickly as possible.

                                                            AMENDED AND RESTATED

   31
                  5.1.2    Thereafter, Net Profit and Net Loss shall be
allocated among the Members in proportion to their respective Percentage
Interests.

         5.2      RESIDUAL ALLOCATIONS. Except as otherwise provided in this
Agreement, all items of Company income, gain, loss, deduction, and any other
allocations not otherwise provided for shall be divided among the Members in the
same proportions as they share Net Profit or Net Losses, as the case may be, for
the Fiscal Year.

         5.3      OTHER ALLOCATION RULES.

                  5.3.1    The Members are aware of the income tax consequences
of the allocations made by this Article 5 and agree to be bound by the
provisions of this Article 5 in reporting their shares of Company income and
loss for income tax purposes.

                  5.3.2    For purposes of determining the Net Profits, Net
Losses, or any other items allocable to any period, Net Profits, Net Losses, and
any such other items shall be determined on a daily, monthly, or other basis, as
determined by the Board of Directors using any permissible method under Code
Section 706 and the Regulations thereunder.

         5.4      TAX ALLOCATIONS.

                  5.4.1    Except as otherwise provided in this Section 5.4, for
income tax purposes each item of income, gain, loss and deduction (collectively,
"Tax Items") shall be allocated among the Members in the same manner as its
correlative item of "book" income, gain, loss or deduction is allocated pursuant
to Sections 5.1 - 5.2.

                  5.4.2    Notwithstanding Section 5.4.1, Tax Items with respect
to Property that is contributed to the Company by a Member shall be shared among
the Members for income tax purposes in accordance with the "traditional method"
pursuant to Regulations promulgated under Section 704(c) of the Code, so as to
take into account the variation, if any, between the book and tax basis of the
Property contributed to the Company.

                  5.4.3    Any elections or other decisions relating to such
allocations shall be made by the Directors in a manner that reasonably reflects
the purpose and intention of this Agreement. Allocations pursuant to this
Section 5.4 are solely for purposes of U.S. Federal, state, and local taxes and
shall not affect, or in any way be taken into account in computing, any Person's
Capital Account or share of Net Profits, Net Losses, other items, or
distributions pursuant to any provisions of this Agreement.

business, property and affairs of the Company shall be managed and all powers of
the Company shall be exercised by or under the direction of the Managing Members
who shall act through their designated representatives as the Board of Directors
("Board of Directors"). Subject to the foregoing, the Members are the "Managers"
of the Company as such term is defined under the Act. Notwithstanding Section
18-402 of the Act, the powers of the Members and the Board of Directors to bind
the Company are as set forth in this Agreement.

         6.2      NUMBER AND DESIGNATION OF DIRECTORS; OBSERVER OF
THIRD PARTY INVESTORS.

                  6.2.1 BOARD OF DIRECTORS. The Company shall have a board of
seven (7) directors ("Directors"). TSMC shall designate four (4) of the
Directors, one (1) of whom shall be voting and three (3) of whom shall be
non-voting. Each of Altera, ADI and ISSI shall designate one (1) voting
Director. Each Director shall serve at the pleasure of the Member who designated
such Director. Only the Member who originally designated a Director may remove
such Director, except that one or more Members holding a Majority in Interest
may remove any Director appointed by a Terminated Member. Any Director may
resign upon written notice to the Member who designated such Director. The
resignation shall take effect upon receipt of such notice, or at such later time
as shall be specified in such notice. Any vacancy occurring for any reason in
the number of Directors shall be filled by the Member who originally designated
the Director whose position has become vacant.

                  6.2.2    OBSERVER. The Third Party Investors may from time to
time designate one representative, approved by TSMC, who shall serve in an
advisory capacity to the Board of Directors, with no other rights, duties or
authority (the "Observer"). TSMC may revoke its approval of a designated
Observer at any time, following which the Third Party Investors shall select an
alternative Observer approved by TSMC. The Observer shall be entitled to attend
such meetings of the Board of Directors as he is invited by the Board of
Directors to attend, and to receive all materials distributed to the Directors
for such meetings. The initial Observer shall be Mr. Quintin Wu.

         6.3      MEETINGS OF DIRECTORS.

                  6.3.1    MEETINGS. Meetings of the Directors shall be held at
least once each calendar quarter and may be called by the Chairman/Chief
Executive Officer ("CEO") of the Company. All meetings shall be held upon seven
(7) days notice by mail or four (4) days notice (or upon such shorter notice
period if necessary under the circumstances) delivered personally or by
telephone, e-mail or facsimile. A notice need not specify the purpose of any
meeting. Notice of a meeting need not be given to any Director who signs a
waiver of notice or a consent to holding the meeting (which waiver or consent
need not specify the purpose of the meeting) or an approval of the minutes
thereof, whether before or after the meeting, or who attends the meeting without
protesting, prior to its commencement, the lack of notice to such Director. All
such waivers, consents and approvals shall be filed with the Company records or
made a part of the minutes of the meeting. A majority of the Directors present,
whether or not a quorum is present, may adjourn any meeting to another time and
place. If the meeting is adjourned for more than 

                                                            AMENDED AND RESTATED

   33
twenty-four (24) hours, notice of any adjournment shall be given prior to the
time of the adjourned meeting to the Directors who are not present at the time
of the adjournment. Meetings of the Directors may be held at any place which has
been designated in the notice of the meeting or at such place as may be approved
by the Directors. Directors may participate in a meeting through use of
conference telephone or similar communications equipment, so long as all
Directors participating in such meeting can hear one another. Participation in a
meeting in such manner constitutes a presence in person at such meeting.

                  6.3.2    QUORUM; ACTION OF THE DIRECTORS. Directors elected by
one or more Members holding a Majority in Interest, present at a meeting shall
constitute a quorum of Directors for the transaction of business. Every action
or resolution done or made by Directors holding a majority of the Director Votes
(as defined below) at a meeting at which a quorum is present is the action of
the Directors. Each voting Director shall hold the same number of votes as the
Percentage Interest held by the Member who designated such Director ("Director
Votes"). If the voting Director of TSMC shall not be present at a meeting, such
voting Director may delegate in writing such Director's voting authority to one
of the non-voting Directors nominated by TSMC. TSMC shall designate which of its
Director nominees shall be its voting Director.

                  6.3.3    ACTION BY WRITTEN CONSENT. Any action required or
permitted to be taken by the Directors may be taken by the Directors without a
meeting, if Directors holding all Director Votes consent in writing to such
action. Such action by written consent shall have the same force and effect as a
unanimous vote of such Directors.

         6.4      POWERS OF DIRECTORS.

                  6.4.1    POWERS OF DIRECTORS. Without limiting the generality
of Section 6.1, but subject to Sections 3.5, 6.4.2 and 6.4.3, and to any express

anniversary of the Effective Date, except with the prior unanimous consent of
the Members or as provided in Sections 3.3.1, 3.3.2.2, 8.1.2, or 10.3 through

provided in Section 6.4.2.8 and the Member proposing to Transfer its Interest
did not consent to the construction of such new foundry by the Company, and (ii)
the provisions of Section 8.5 have been complied with. A Transfer pursuant to

of, any other right or remedy which the non-breaching Members may have, at law
or in equity, or pursuant to Article 10, all subject to Article 21.

         8.2      GENERAL TRANSFER PROVISIONS. Notwithstanding any other
provisions of this Agreement:

                  8.2.1    NO VIOLATION OF LAW. No portion of, or interest in,
an Interest may be the subject of a Transfer without assurances to the Company
that are satisfactory to non-transferring Members that the proposed Transfer
does not violate any law applicable to the Company. The Members may, among other
things, require (i) a written opinion addressed to the Company, in form and
substance satisfactory to the non- transferring Members, of legal counsel
acceptable to the non-transferring Members, to the effect that the proposed
Transfer is exempt from registration under the Securities Act of 1933, as
amended (or a "no action" letter from the staff of the Securities and Exchange
Commission satisfactory to the non-transferring Members, to the effect that such
Transfer is exempt from such registration); (ii) registration under applicable
state securities laws or a written opinion addressed to the Company, in form and
substance satisfactory to the non-transferring Members, of legal counsel
acceptable to the Company, to the effect that such Transfer is exempt under
applicable state securities laws; (iii) a written opinion addressed to the
Company, in form and substance satisfactory to the non-transferring Members, of
legal counsel acceptable to the non- transferring Members, to the effect that
any such contemplated Transfer will not require the Company to register under
the Investment Company Act of 1940, require that the Company or any Member
register as an investment adviser under the Investment Advisers Act of 1940, or
cause the Company to lose its partnership status for U.S. Federal income tax
purposes; and (iv) representations and warranties concerning the facts and
                                                            AMENDED AND RESTATED
                                             LIMITED LIABILITY COMPANY AGREEMENT

circumstances establishing the basis for the availability of exemptions from
registration under the Securities Act of 1933, the Investment Company Act of
1940, the Investment Advisers Act of 1940, and other reasonable assurances
relating to any other applicable laws, from the proposed substituted or proposed
transferee Member.

                  8.2.2    TRANSFEREE TO BE BOUND BY THIS AGREEMENT. In addition
to any other requirements contained in this Agreement pertaining to a Transfer
of Interests, as a condition precedent to any Transfer, the prospective
transferee shall, for the express benefit of the Company and each
non-transferring Member, agree to be bound by all of the terms of this Agreement
and to make such reasonable representations and warranties as the Members may
request.

                  8.2.3    DELAY IN TRANSFER. Except as may occur upon
conversion of the Company or upon transfers of Interest to a corporation
pursuant to Section 14.1, if, in the determination of the non-transferring
Members, a proposed Transfer would, alone or in conjunction with one or more
other Transfers cause the Company to lose its partnership status or terminate
its partnership existence for U.S. Federal income tax purposes, such Transfer
(if otherwise permitted) shall be delayed in whole or in part until the earliest
time as determined by the non-transferring Members that such Transfer may occur
without causing the Company to lose its partnership status or to terminate for
U.S. Federal income tax purposes. If at any time more than one Transfer is being
delayed under this Section 8.2.3, such Transfers shall be made in the order in
which the Company received written notice of the proposed Transfers under this
Section.

                  8.2.4    LIABILITY OF TRANSFEROR. Except as may occur upon
conversion of the Company or upon Transfers of Interest to a corporation
pursuant to Section 14.1, any Member who voluntarily Transfers or attempts to
Transfer any portion of or interest in its Interest, if such a Transfer causes
or would cause the Company to lose its partnership status or terminate its
partnership existence for U.S. Federal income tax purposes, shall be liable to
the Company and promptly shall pay for any incremental costs, taxes, fines,
penalties, damages or losses which may be due from the Company or the Members or
suffered by the Company or the Members, including costs of enforcement of the
Company's power to void or otherwise prohibit such Transfer or attempted
Transfer.

                  8.2.5    NO RELEASE. No Transfer of all or any portion of, or
interest in, an Interest, whether or not in compliance with this Article 8 and
even if it results in the substitution of the transferee as a new Member, shall
release the transferor from those liabilities to the Company which survive such
Transfer.

         8.3      PREEMPTIVE RIGHTS.

                  8.3.1    PREEMPTIVE RIGHT. Subject to Section 8.6, if the
Company shall propose to issue, sell or distribute any Membership Interest or
any option, warrant or right to acquire, or any security convertible into or
exchangeable for any of the foregoing, each Member shall, subject to the
provisions of Section 8.6, have a right of first refusal to participate in such
issuance, sale or distribution on a pro rata basis according to the Percentage
Interest held by each 

                                                            AMENDED AND RESTATED
                                             LIMITED LIABILITY COMPANY AGREEMENT
                                       35
   43
Member so that following such issuance, sale or distribution each Member would
acquire or have the right to acquire, if each Member had elected to acquire such
Member's pro rata portion, the same Percentage Interest in the Company as each
Member had by reasons of such Member's Percentage Interest prior to such
issuance, sale or distribution.

                  8.3.2    PROCEDURE. The Company shall provide each Member with
notice of any such proposed issuance which notice shall specify the nature of
the proposed issuance, the consideration to be received therefor, the identity
of the proposed purchaser, and the terms upon which such issuance shall be
undertaken. Each Member shall have the right to elect to purchase from the
Company a portion of the Interest referred to in the notice at the same price
and on the same terms as specified in the notice for a period of sixty (60) days
after the giving of the notice but not thereafter. A Member shall exercise this
right by delivering in writing to the Company notice of such Member's intent to
purchase such Member's pro rata share along with the purchase price therefore.
If any Member shall elect to purchase none, or less than all of the offered
Interest, the other Members shall have the right to purchase the pro rata share
of the Member who has declined to purchase the offered Interest, according to
each purchasing Member's pro rata share of such Interest, for a successive
period of thirty (30) days thereafter. All or any portion of the Interest not so
purchased may be issued as specified in the notice within a period of forty-five
(45) days after the expiration of such ninety (90) day period specified above.

                  8.3.3    LIMITATION. Notwithstanding the foregoing, the
provisions of this Section 8.3 shall not apply to any of the following: (i) any
issuance, sale or distribution in connection with the conversion of each
Member's Interest in the Company to an interest in the Delaware Corporation as
provided for in Article 14, (ii) the transactions contemplated by Sections
3.3.1, 3.3.2, 3.5.4 or 10.5, or (iii) any option, warrant or other rights
granted to Officers, Directors or employees of the Company pursuant to the
Incentive Plan.

         8.4      ADMISSION OF NEW MEMBERS. A new Member may be admitted to the
Company only if Section 8.3 has been complied with and upon the written consent
of Members holding not less than 71% in Percentage Interest (without
consideration of the Percentage Interest of any Defaulting Member, Selling
Member, Terminated Member or Non-Paying Member). Prior to any new Member
acquiring the Interest of a Managing Member, the Managing Member proposing to
Transfer its Interest shall disclose to the other Members, whether it is
proposed that the new Member shall, following the Transfer, designate such
Managing Member's representative on the Board of Directors, and hold the
decision making authority of the Managing Member for decisions which pursuant to
this Agreement require the consent of the Managing Members. Any Transfer
approved pursuant to the first sentence of this Section shall then be an
approval of the Transfer of the rights specified in the disclosure notice.

                  8.4.1    CAPITAL CONTRIBUTION. The type and amount of Capital
Contribution which must be made by a new Member shall be determined by the
written consent of Members holding not less than 71% in Percentage Interest
(without consideration of the Percentage Interest of any Defaulting Member,
Selling Member, Terminated Member or Non-Paying Member).
                                                            AMENDED AND RESTATED
                                             LIMITED LIABILITY COMPANY AGREEMENT

   44
                  8.4.2    TIME OF ADMISSION. A new Member shall not be deemed
admitted into the Company until the Capital Contribution required of such Person
shall have been made and such Person has become a party to this Agreement.

                  8.4.3    ADJUSTMENT OF INTERESTS. Upon admission of a new
Member, the Percentage Interests of all previously existing Members shall be
adjusted to reflect the addition of such new Member and such new Member's
Capital Contribution.

         8.5      RIGHT OF FIRST REFUSAL.

                  8.5.1    If any Member ("Selling Member") intends to Transfer
its Interest or any part thereof (the "Offered Interest") (except to a
wholly-owned subsidiary) it shall notify the Company and the other Members of
its intention to do so ("Offering Notice"). The Offering Notice shall specify
the nature of the Transfer, the consideration to be received therefor, the
identity of the proposed purchaser (or lender, as the case may be), and the
terms upon which such Member intends to undertake such Transfer. Within thirty
(30) days after receipt of the Offering Notice, the Members other than the
Selling Member shall have the right, but not the obligation, subject to Section
8.6, to elect to purchase from the Selling Member a portion of the Offered
Interest referred to in the Offering Notice at the same price and on the same
terms as specified in the Offering Notice for a period of thirty (30) days after
the giving of the Offering Notice (or make the loan, if the same involves an
encumbrance, hypothecation or mortgage, upon the same terms on which said loan
was to be made therefor) by delivering in writing to the Company an offer to
purchase (or loan) a portion of the Offered Interest of the Selling Member. Each
Member so electing to purchase shall be entitled to purchase a portion of such
Offered Interest in the same proportion that such Member's Percentage Interest
bears to the aggregate of the Percentage Interests of all of the Members
electing to purchase the Offered Interest. In the event any Member elects to
purchase less than all of such Member's pro rata share of such Offered Interest
("Shortfall"), subject to Section 8.6, the other Members may elect to purchase
their pro rata share of the Shortfall. Within sixty (60) days after the election
notice of the Members who so elect, the purchase shall be consummated on the
terms and conditions set forth in the Offering Notice of the Selling Member (or
if the same involves a mortgage, encumbrance or other hypothecation, the loan
shall be consummated upon the terms and conditions of the loan set forth in the
Offering Notice).

                  8.5.2    If none of the other Members elect to purchase the
Offered Interest (or elect to make the loan specified), or the election is made
for less than all of the Offered Interest, then the Selling Member, subject to
Section 8.6, within thirty (30) days after the expiration of said sixty (60) day
period, may undertake and complete the Transfer to any Person the identity of
which was disclosed in the Offering Notice for that portion of the Offered
Interest not undertaken to be purchased by the other Members provided, however,
that the proposed transferee has been approved by the other Members as specified
in Sections 8.1.1, 8.1.3, and 8.4, as such Sections may be applicable to the
Transfer, and the provisions of Section 8.6 have been complied with. The
Transfer shall not be undertaken at a lower price or upon more favorable terms
than specified in the Offering Notice. If the Selling Member does not then
consummate the original proposed Transfer within ninety (90) days after the date
of the Offering Notice, or within the time scheduled

                                                            AMENDED AND RESTATED

   45
for closing by the purchasing person, firm or corporation, whichever is later,
then all restrictions of this Section shall apply as though no Offering Notice
had been given.

         8.6      SPECIAL TRANSFER PROVISION. Any Managing Member who elects
pursuant to Sections 3.3, 8.1, 8.5 or 10.3 of this Agreement to acquire an
additional Interest in the Company (which Interest was previously held by or was
to be held by a Managing Member) shall at the time such Member's Percentage
Interest is increased also have an increase in such Member's rights and
obligations to purchase the output of the Foundry pursuant to the Purchase
Agreement or Future Purchase Agreement corresponding to the additional
Percentage Interest being acquired. Any New Buyer which acquires pursuant to
Section 3.3, 8.1, 8.5 or 10.3 hereof an Interest that was previously held by a
Managing Member or other Person holding rights and obligations to purchase the
output of the Foundry pursuant to the Purchase Agreement or Future Purchase
Agreement shall at the time of such acquisition acquire rights and obligations
to purchase the output of the Foundry corresponding to the Percentage Interest
being acquired. If at any time (a) a Member's or other Person's Percentage
Interest changes as a result of (i) a Transfer in accordance herewith, (ii) a
failure to pay a Second Part Capital Contribution, Third Part Capital
Contribution, or Additional Capital Contribution, (iii) a failure to guarantee a
loan to the Company in accordance herewith, (iv) an Event of Default, or (v) any
other provision hereunder and (b) in the reasonable opinion of the Board of
Directors, such change, in conjunction with the provisions herein and in the
Purchase Agreement or Future Purchase Agreement for adjusting the Managing
Members' purchase rights or obligations under such agreements, produces an
inequitable or unintended result, then the Board of Directors, with the
concurrence of all Managing Members that are parties to the Purchase Agreement
or Future Purchase Agreement, may adjust the purchase rights and obligations of
such Members in such manner as the Board of Directors determines in good faith
is equitable under the circumstances.

         8.7      SPECIAL RIGHT OF MANAGING MEMBERS OTHER THAN TSMC TO PURCHASE.
This Section shall apply if pursuant to Sections 3.3, 8.3, 8.5, or 10.3 of this
Agreement, TSMC provides notice to the Company of its intention to acquire an
additional Interest in the Company which, after the Percentage Interests of all
Members are adjusted in connection with such transaction, would result in TSMC
having a Percentage Interest which, when combined with the Percentage Interest
of the Third Party Investors', would equal or exceed a 71% Percentage Interest.
Prior to the completion of any such transaction, the Board of Directors shall
provide written notice to each Managing Member of this provision and the option
of such Managing Members (other than TSMC and excluding any Managing Member
whose Interest is being offered pursuant to Sections 3.3, 8.5 or 10.3 of this
Agreement (the "Subject Interest")) to purchase, in addition to their pro rata
portion of the Subject Interest, a pro rata portion of the Excess Subject
Interest (including the right to purchase a pro rata portion of any shortfall
resulting from another Member's election to purchase less than its entire pro
rata allocation). As used in this Section 8.7, the term "Excess Subject
Interest" means the portion of the Subject Interest which TSMC has elected to
purchase which would cause TSMC and the Third Party Investors to jointly hold a
Percentage Interest equal to or exceeding 71%. Each such Managing Member shall
have the right to purchase its pro rata share of the Excess Subject Interest by
giving notice within thirty (30) days of the notice received from the Board of
Directors pursuant to this Section of such Member's intent to acquire its pro
rata share of the Excess Subject 

                                                            AMENDED AND RESTATED

Interest, TSMC may proceed with its acquisition of any portion of the Excess
Subject Interest not so acquired.

                    BOOKS, RECORDS, REPORTS AND BANK ACCOUNTS

         9.1 MAINTENANCE OF BOOKS AND RECORDS. The Company shall cause books and

Economic Interest;

                  9.1.2 A copy of the Certificate of Formation and any
amendments thereto, together with any powers of attorney pursuant to which the

Company; and

                  9.1.8 Other information regarding the affairs of the Company
as is reasonable or prudent.

         9.2 INSPECTION RIGHTS. Each Member and each holder of an Economic
Interest has the right upon reasonable request, for purposes reasonably related
to the interest of that Person as a Member or holder of an Economic Interest, to
inspect and copy during normal business hours any of the books and records
required to be maintained in accordance with Section 9.1. Such right may be
exercised by such Person or by that Person's agent or attorney.

         9.3 RIGHTS TO RECEIVE COPIES OF DOCUMENTS. Upon the request of a Member

         9.5 TAX MATTERS HANDLED BY TAX MATTERS PARTNER.

                  9.5.1 TSMC is hereby designated the "Tax Matters Partner" (as
defined in Code Section 6231), and is authorized and required to represent the
Company (at the Company's expense) in connection with all examinations of the
Company's affairs by tax authorities, including administrative and judicial
proceedings, and to expend Company funds for professional services and costs
associated therewith. The Tax Matters Partner will control all decisions with
respect to such proceedings, but will keep the Board of Directors and other
Managing Members reasonably informed with respect to such proceedings and will
provide the other Managing Members the opportunity to offer comments and
suggestions with respect to such proceedings to the extent practicable. Each
Member agrees to cooperate with the Tax Matters Partner and to do or refrain
from doing any or all things reasonably requested by the Tax Matters Partner
with respect to the conduct of such proceedings. The Tax Matters Partner shall
arrange for the preparation and timely filing of all returns required to be
filed by the Company. Any Member receiving advice that the Internal Revenue
Service or any state or foreign revenue service intends to examine any income
tax return of the Company shall promptly notify the Tax Matters Partner.

                  9.5.2 The Tax Matters Partner shall exert commercially
reasonable efforts to adopt positions and make elections for tax purposes which
(i) minimize the sum of the current taxable income and gain, and (ii) maximize
the sum of the current taxable losses, deductions, and

                                                            AMENDED AND RESTATED

   48
credits, to the Managing Members as a group. In addition, notwithstanding any
other provision of this Agreement, the Tax Matters Partner shall cause all
Company tax returns and other related tax filings to be prepared in such manner
as to reflect that any income, gain, loss, or deduction recognized by the
Company as the result of an adjustment, reallocation or recharacterization by
any tax authority of the tax treatment of any transaction between the Company
and a Member or an Affiliate of a Member as originally reported on any tax
return filed for the Company shall be specially allocated to such Member for the
taxable year of the adjustment, reallocation or recharacterization and for each
taxable year thereafter so that the tax consequences to the other Members shall,
to the extent possible, have the same cumulative aggregate tax consequences as
if no such adjustment, reallocation or recharacterization had occurred. No such
adjustment shall be reflected in the Capital Accounts of the Members. Not less
than thirty (30) days before actual filing, the Tax Matters Partner shall
provide to all of the other Managing Members a copy of each of the final returns
and other administrative or judicial filings of the Company relating to income
taxation, and during this period, shall provide the other Managing Members with
the opportunity to comment on such returns and filings. The Members agree that,
except as otherwise approved in advance by the Board of Directors, no Member
shall take any position in any such administrative proceeding inconsistent with
the tax returns filed by the Company, provided such tax returns are prepared in
a manner consistent with this Agreement. Nothing in this Agreement shall be
construed to provide the Tax Matters Partner with rights, powers or privileges
relating to tax administrative proceedings in excess of the minimum rights,
powers and privileges provided to the Tax Matters Partner by Code sections 6221,
et. seq., and the Treasury Regulations thereunder.

         9.6 FEDERAL INCOME TAX ELECTIONS MADE BY TAX MATTERS PARTNER. Except as
otherwise provided herein, the Tax Matters Partner on behalf of the Company may
make all elections for U.S. Federal, state and local income tax purposes,
including but not limited to, the following:

                  9.6.1 USE OF ACCELERATED DEPRECIATION METHODS. To the extent
permitted by applicable law and regulations, the Company may elect to use an
accelerated depreciation method on any depreciable unit of the assets of the
Company.

                  9.6.2 ADJUSTMENT OF BASIS OF ASSETS. In case of a transfer of
all or part of the Interest of any Member, the Company may elect, pursuant to
Sections 734, 743, and 754 of the Code, to adjust the basis of the assets of the
Company.

         9.7 OBLIGATIONS OF MEMBERS TO REPORT ALLOCATIONS. The Members are aware
of the income tax consequences of the allocations made by this Agreement and
hereby agree to be bound by the provisions of this Agreement in reporting their
shares of the Company income and loss for income tax purposes in a manner
consistent with the tax returns filed by the Company, provided such tax returns
are prepared in a manner consistent with this Agreement.

                                                            AMENDED AND RESTATED

                   EVENT OF DEFAULT; TERMINATION OF MEMBERSHIP

         10.1 EVENT OF DEFAULT. The occurrence of any one or more of the
following events shall be a breach and a default ("Event of Default") hereunder:

                  10.1.1 A Member shall fail to perform a material obligation of
this Agreement or of any of the Ancillary Agreements and, (except for breaches
contemplated in Sections 10.1.5 or 10.1.6 of this Agreement, which provide for
no opportunity to cure, and except for breaches for which another cure period is
specified herein), does not cure or remedy the default within sixty (60) days
thereafter. Notwithstanding the foregoing, the breach or failure to perform any
of the following Sections shall not be, or be deemed to be, an Event of Default:
Sections 3.3.1, 3.3.2, and 3.5.4 (each of which shall be treated as provided in
such Sections ).

                  10.1.2 Any representation, warranty or statement made by a

         10.2 TERMINATION OF MEMBER. If an Event of Default occurs and is not

defaulting Member shall be terminated as a Member, and all rights and privileges
of such former Member under this Agreement shall be adjusted and disposed of as
follows:

                  10.2.1 If the Event of Default is as provided or described in
any of Section 10.1.1, Section 10.1.2 or Section 10.1.5, the Member shall be
terminated as a Member upon the vote of the non-defaulting Members with a
majority of the Interests held by non-defaulting Members.

                  10.2.2 For all other Events of Default, termination of
Membership shall occur immediately following the elapse of the specified cure
period, if any.

                  10.2.3 Notwithstanding any other provision of this Agreement
and subject to Section 11.2.3, the termination of a Member ("Terminated Member")
as contemplated in this Section 10.2 shall not affect the rights of any other
Member (a "Remaining Member") under this Agreement. The Company shall promptly
notify a Terminated Member of such termination, but the failure to give such
notice shall not affect such termination or create any rights in the Terminated
Member.

         10.3 PURCHASE RIGHT. Unless provided otherwise in this Agreement, upon
termination of a Terminated Member as contemplated in Section 10.2, the
Remaining Members shall have the right to purchase and the Terminated Member
shall have the obligation to sell, the Terminated Member's Interest as provided
in Sections 10.3 through 10.7, inclusive. The purchase price for such Interest
shall be an amount equal to 50% of the lesser of (i) the Terminated Member's
Percentage Interest in the book value of the Company as of such termination
date, or (ii) the fair market value of the Terminated Member's Interest as of
such termination date as determined in the reasonable discretion of the Board of
Directors, not including any Director appointed by the Terminated Member. Such
reduction in value shall constitute partial compensation for damages suffered by
the Remaining Members as a result of the act, omission or condition which
resulted in the termination of the Terminated Member, and subject to Article 21,
shall be in addition to, and not in lieu of any other right or remedy which the
Remaining Members may have, at law or in equity, or pursuant to this Agreement.
The Directors shall give notice to all Remaining Members of such purchase price.

                                                            AMENDED AND RESTATED

   51
         10.4 NOTICE OF INTENT TO PURCHASE. Within thirty (30) days after the
Directors have determined and notified the Remaining Members as to the purchase
price of the Terminated Member's Interest determined in accordance with Section 
10.3, each Remaining Member shall have the right, but not the obligation, to
elect to purchase a portion of the Terminated Member's Interest. Any Remaining
Member so electing shall notify the Directors in writing within thirty (30) days
after the notice from the Directors of such Remaining Member's desire to
purchase a portion of the Terminated Member's Interest. The failure of any
Remaining Member to submit such notice within the applicable period shall
constitute an election on the part of the Remaining Member not to purchase any
of the Terminated Member's Interest. Each Remaining Member so electing to
purchase shall be entitled to purchase a portion of the Terminated Member's
Interest in the same proportion that the Percentage Interest of the Remaining
Member bears to the aggregate of the Percentage Interest of all of the Remaining
Members electing to purchase the Terminated Member's Interest.

         10.5 ELECTION TO PURCHASE LESS THAN ALL OF THE TERMINATED MEMBER'S
INTEREST. If any Remaining Member elects to purchase none or less than all of
such Remaining Member's pro rata share of the Terminated Member's Interest
("Shortfall Amount"), then subject to the provisions of Section 8.6, the other
Remaining Members may elect to purchase the Shortfall Amount in proportion to
their respective Percentage Interests. Each Remaining Member who purchases part
of the Terminated Member's Interest shall succeed to a pro rata share of the
Terminated Member's Capital Account balance. If the Remaining Members do not
purchase the entire Interest of the Terminated Member, then subject to the
provisions of Section 8.6, with respect to all or any remaining share of the
Terminated Member's Interest, one or more new Members, if approved pursuant to
Section 8.4, may be admitted as a Member or Members and purchase the Terminated
Member's remaining Interest by paying for the Interest in cash. If the entire
Interest of the terminated Member is not purchased, the Terminated Member shall
have only an Economic Interest, and without limiting the generality of the
foregoing, shall not be a Managing Member, shall not be entitled to designate a
Director hereunder and any current Director or Directors appointed by such
Terminated Member shall be deemed to be removed and the number of Directors on
the Board of Directors shall be reduced accordingly. In such event as partial
compensation for damages suffered by the Company and the Remaining Members, (i)
the Terminated Member's remaining Interest shall be reduced by fifty percent
(50%) and the Remaining Members' Interests shall be increased pro rata
accordingly, (ii) the Terminated Member's Capital Account Balance following the
purchase of any Remaining Member, if any, shall be reduced by 50%, and the
difference shall be added to the Capital Account Balances of the Remaining
Members, pro rata according to their Interests, and (iii) solely for purposes of
determining the Managing Members' and a Terminated Member's rights and
obligations to purchase the output of the Foundry under the Purchase Agreement
or Future Purchase Agreement (which rights and obligations shall be a function,
to be specified in each of those agreements, of the Managing Members' and
Terminated Member's Percentage Interests), effect shall not be given to any
increase or decrease in a Managing Member's or Terminated Member's Percentage
Interest attributable to the operation of clause (i).

                                                            AMENDED AND RESTATED

         10.6 PAYMENT OF PURCHASE PRICE. The purchase price shall be paid by the
electing Remaining Members by either of the following methods, each of which may
be selected separately by the electing Remaining Members in their respective
sole discretion:

                  10.6.1 The Remaining Members shall at the consummation of the
purchase of the Terminated Member's Interest ("Closing") pay in cash the total
purchase price for the Terminated Member's Interest; or

                  10.6.2 The Remaining Members shall pay at the Closing
one-fifth (1/5) of the purchase price in cash and the balance of the purchase
price shall be paid in four equal annual principal installments, plus accrued
interest, and be payable each year on the anniversary date of the Closing. The
unpaid principal balance shall accrue interest at the current applicable U.S.
Federal rate as provided in the Code for the month in which the initial payment
is made, but the Remaining Members shall have the right to prepay in full or in
part at any time without penalty. The obligation of each purchasing Remaining
Member to pay its portion of the balance due shall be evidenced by a separate
promissory note executed by the respective Remaining Member. Each such
promissory note shall be in an original principal amount equal to the portion
owed by the respective purchasing Remaining Member. The promissory note executed
by each purchasing Remaining Member shall be secured by a pledge of that portion
of the Terminated Member's Interest purchased by such Remaining Member.

         10.7 CLOSING OF PURCHASE OF TERMINATED MEMBER'S INTEREST. The Closing
for the sale of a Terminated Member's Interest pursuant to this Article 10 shall
be held at 10:00 a.m. at the principal office of Company no later than sixty
(60) days after the determination of the purchase price. At the Closing, the
Terminated Member or such Terminated Member's legal representative shall deliver
to the electing Remaining Members an instrument of transfer (containing
warranties of title and no encumbrances) conveying the Terminated Member's
Interest free and clear of all liens, charges and encumbrances whatsoever,
except as permitted by the purchaser thereof. The Terminated Member or such
Terminated Member's legal representative, the Company and the Remaining Members
shall do all things and execute and deliver all documents as may be necessary or
convenient to consummate such sale and purchase in accordance with the terms and
provisions of this Agreement. Without limiting the generality of the foregoing,
each Member hereby appoints each Remaining Member as its attorney-in-fact and
agent, with full power and authority to take all actions and execute and deliver
all agreements, deeds, leases, releases, assignments, bills of sale, security
instruments and any other document which, in the sole judgment of such Remaining
Member, is necessary or convenient to consummate such sale and purchase.

87% in Percentage Interest if the dissolution does not occur contemporaneously
with an IPO of the Delaware Corporation;

                  11.2.2 The action of the Board of Directors if such action

                  11.2.3 The death, retirement, insanity, incapacity,
resignation, expulsion, bankruptcy or dissolution of a Managing Member, or the
occurrence of any other event which terminates a Managing Member's continued
membership in the Company, unless the business of the Company is continued with
the written consent of other Members holding a Majority in Interest of such
other Members within ninety (90) days following the occurrence of such event;

                  11.2.4 The appointment of a receiver, trustee or liquidator of

Members within sixty (60) days from said Governmental Intervention and the
Managing Members hereto shall have entered into good faith negotiations with the
objective of restructuring the relationship among the Members in a manner such
that the adverse effect of said alteration or modification of this Agreement
will be minimized and following which, the Managing Members cannot unanimously
reach a reasonably acceptable modification to this Agreement, within six (6)
months from the date of dispatch of said written request, or within such longer
period of time as mutually agreed upon by the unanimous consent of the Managing
Members.

                  11.2.7 On the thirtieth (30th) anniversary of the date of the
filing of the Certificate of Formation of the Company.

         11.3 WINDING UP. Upon the dissolution of the Company, TSMC (or if TSMC

of the remaining Members), shall wind up the affairs of the Company (such Person
or Persons herein collectively called the "Liquidating Person"). Upon
dissolution of the Company and until the filing of the certificates of
cancellation pursuant to Section 11.6, the Liquidating Person may, in the name
of, and on behalf of, the Company, prosecute and defend suits, whether civil,
criminal or administrative, gradually settle and close the Company's business,

liquidating trustee. The Liquidating Person shall be entitled to reimbursement
for out-of-pocket expenses incurred and reasonable compensation for services
rendered in connection with the winding up and liquidation of the Company, as
agreed by the Members. Such reimbursement shall be paid as an expense of the
Company after all debts to third parties have been repaid or adequately provided
for but before any repayment of loans or advances by Members.

         11.4 DISTRIBUTION OF ASSETS. The Members shall continue to divide Net
Profit and Net Loss and Cash Available For Distribution during the winding-up
period in the same manner and the same priorities as provided for in Articles 4
and 5 hereof. The proceeds from the liquidation of Property shall be applied in
the following order:

                  11.4.1 To the payment of creditors, including Members who are
creditors, in satisfaction of liabilities of the Company (whether by payment of
the making or reasonable provision for payment thereof) other than liabilities
for which reasonable provision for payment has been made and liabilities to
Members for distributions pursuant to Article 4;

                  11.4.2 To set up reasonable reserves for contingent or
unforeseen liabilities of the Company, to be maintained in a regular trust fund
account;

                  11.4.3 To repay pro rata all loans or advances made by the
Members to the Company, but in the event the amount available for such repayment
shall be insufficient, then pro rata on account thereof; and

                  11.4.4 The balance if any, shall be paid or distributed to the
Members in proportion to their Percentage Interests; except, if the Company
shall be dissolved prior to the expiration of the period beginning on the
Effective Date and ending five years from the date of Commencement of
Production, as defined in the Purchase Agreement (the "Subordination Period")
and if such dissolution is as a result of an event of Force Majeure or a major
economic or business event or condition such that the economic or business
assumptions underlying the Business Plan have changed to the extent that it is
economically impracticable to substantially implement the Business Plan
(including, but not limited to, major claims or litigation against the Company,
failure to operate the Foundry on an economically viable basis, a change in
technology rendering the business of the Company obsolete, or a major economic
recession), and the Board has determined to dissolve the Company with the
approval of the Members as provided in Section 11.2.1, then the Manufacturing
Agreement, the Technology License and Assistance Agreement, and the Advanced
Process Agreement (collectively and together with the other property listed as
contributed by TSMC on Exhibit A, the "TSMC Contributed Property") shall each be
terminated and the balance of the proceeds from the liquidation of Property
shall be paid or distributed to the Members as follows: (i) first, to the
Members in reverse chronological order (last in, first out), until the entire
Cash Contribution of each is returned to each Member, without any interest, and
(ii) the rest, residue and remainder, if any, to the Members in accordance with
each Member's Percentage Interest. For purposes of the preceding sentence, TSMC
shall be treated as if it had contributed pursuant to the First Part Capital
Contribution described in Section 3.1.1 hereof, an amount of cash ("Property
Cash"), in addition to the cash contribution of TSMC described in such Section 
3.1.1, equal to the product of (x) the initial agreed value of the TSMC

purposes of this Section 11.4.4, the term "Permitted Percentage" shall be and
mean zero percent (0%) on and before the Commencement of Production, increasing
daily thereafter at an annual rate of twenty percent (20%) until the Permitted
Percentage is one hundred percent (100%) on the last day of the Subordination
Period.

Where the distribution pursuant to this Section 11.4 consists both of cash (or
cash equivalents) and non-cash property, the cash (or cash equivalents) shall
first be distributed, in a descending order, to fully satisfy each category
starting with the most preferred category above. To the maximum extent
practicable consistent with the foregoing, non-cash property shall be returned
to the Member which has contributed it.

         11.5 TIME FOR WINDING UP. A reasonable time shall be allowed for the
orderly liquidation of assets of the Company and the discharge or other
provision of liabilities to creditors so as to enable the Liquidating Person to
minimize any losses attendant upon a liquidation.

         11.6 FINAL ACCOUNTING; CERTIFICATES OF CANCELLATION. Each of the
Members shall be furnished with a statement, prepared by the Company's
independent certified public accountant, setting forth the assets and
liabilities of the Company as of the date of the complete liquidation. Upon the
compliance by the Liquidating Person with the foregoing distribution plan, the
Members shall cease to be such, and the Liquidating Person shall execute and
cause to be filed any and all documents necessary with respect to the
termination and cancellation of the Company, including, without limitation, a
certificate of cancellation under Section 18-203 of the Act.

                            EXECUTIVE INCENTIVE PLAN

Executive Incentive Plan in the form approved by the Board of Directors on the
Effective Date, with an initial award of option rights as set forth in Section 7
of the Executive Incentive Plan. The Executive Incentive Plan shall be
administered by the Board in accordance with its terms. In no event shall the
rights awarded under any Incentive Plan exceed an aggregate of 5% in Percentage
Interests.

         12.2 ADMISSION OF PARTICIPANTS. Upon exercise of an option or payment
of an award with an equity interest in the Company, and payment of any
applicable purchase price determined in the discretion of the Board of Directors
and execution of a counterpart of this Agreement, a participant shall be
admitted as a Member with a Percentage Interest as earned under the Executive
Incentive Plan. Such participant shall have an initial Capital Account with
respect to the acquired Interest equal to the amount determined by multiplying
the participant's Percentage Interest with respect to the acquired Interest
times the amount determined by dividing (i) the aggregate sum of all Capital
Accounts of the Members prior to the transfer of the Interest

acknowledge that as part of the Initial Capital Contribution of TSMC, and as a

Interests in the Company. TSMC agrees to meet and confer with the Managing
Members prior to exercise of TSMC's rights under the TSMC Land Option, in order
to discuss the participation of the Managing Members in any venture related
thereto.

         13.3 FURTHER ASSURANCES. The Members, from time to time and as

Delaware general corporation or a parent or a subsidiary of a Delaware
corporation, at such time, in such manner and on such basis as the Board of
Directors shall determine is in the best interests of the Company. Such change
or conversion to a Delaware general corporation may be accomplished by a direct
merger into a corporation, by one of the methods illustrated in Exhibit E, or by
any other method the Board of Directors determines is desirable, provided,
however, that each Member shall have the right to participate in proportion to

which through one transaction or a series of transactions involves the
conversion or exchange of the Interests of those Members who choose to
participate in such transaction into an interest in or the stock of such
corporation in proportion to a Member's Interest in the Company as adjusted to
reflect the participation of the other Members. Additionally, by execution and
delivery of this Agreement, each Member agrees to take any and all actions
necessary to consummate such a change or conversion, including, but not limited
to, the execution and delivery of an Agreement of Merger or Consolidation and
filing of a Certificate of Merger or Consolidation with the Office of the

converted into or exchanged for an interest or shares in the Delaware
Corporation, each of the Members shall use its best efforts to cause the
Delaware Corporation to assume all rights, duties and obligations ascribed to it
in the Registration Rights Agreement. In the event any Member's shares of the
Delaware Corporation are included for sale in the initial public offering, each
Member shall be entitled to include such Member's shares of the Delaware
Corporation in such initial public offering on a pro rata basis.

         14.3 VOTING ARRANGEMENTS.

                  14.3.1 CONVERSION CONTEMPORANEOUSLY WITH IPO. Each Member
agrees that if the conversion or exchange of each Member's Interest into an
interest in the Delaware Corporation occurs contemporaneously with an IPO of the
Delaware Corporation, then such Member shall execute and deliver a voting
agreement or other arrangement with a term and on such terms as may be specified
by TSMC, whereby TSMC shall have authority to designate the majority of the
board of directors of the Delaware Corporation. Each Member shall take any and
all actions necessary and execute any and all documents necessary to give TSMC
such authority.

                  14.3.2 CONVERSION NOT CONTEMPORANEOUSLY WITH IPO. Each Member
agrees that if the conversion or exchange of each Member's Interest into an
interest in the Delaware Corporation is not contemporaneous with an IPO of the
Delaware Corporation, then the Articles, Bylaws, Stockholder's Agreement, and
other governing documents of the Delaware Corporation shall provide for
corporate governance substantially equivalent to that of the Company as set
forth in this Agreement.

         14.4 OPTIONS. In the event that each Member's Interest is converted or
exchanged into an interest in or shares of the Delaware Corporation, any
outstanding options, warrants or right to securities of the Company shall be
changed or converted into similar securities of the Delaware Corporation on the
same basis as a Member's Interest is changed or converted to an interest in or
shares of the Delaware Corporation.

                        STANDARD OF CARE; INDEMNIFICATION

         15.1 STANDARD OF CARE. Each Director, Officer, employee and agent shall
perform its, his or her duties to the Company in good faith, in a manner he, she
or it reasonably believes to be in or not opposed to the best interests of the
Company, and with the care that a prudent person in a similar position would use
under similar circumstances. Each Director, Officer, employee and agent of the
Company and any Liquidating Person (individually, an "Indemnitee" and
collectively, the "Indemnitees") acting in such capacity shall be fully
protected in relying in good faith on information, opinions, reports or
statements, including financial statements, books of account and other financial
data, if prepared or presented by (i) one or more Directors, Officers or
employees of the Company who the Indemnitee reasonably believes are reliable and
competent in the matters prepared or presented, or (ii) legal counsel, certified
public accountants or other persons as to matters that the Indemnitee reasonably
believes are within the person's professional or expert competence. No
Indemnitee shall be liable for damages to the Company or any present or former
Member with respect to claims relating to its conduct for or on behalf of the
Company, except to the extent that there is a final judicial determination based
on clear and convincing evidence that (a) its action or failure to act involved
an act or omission undertaken with deliberate intent to cause injury to the
Company or undertaken with reckless disregard for the best interests of the
Company, or (b) with respect to any criminal action, proceeding or
investigation, it had no reasonable cause to believe its conduct was unlawful.

         15.2 INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS. The
Company shall indemnify, defend and hold harmless each Indemnitee from and
against any and all claims, demands, causes of action, loss, liability, cost, or
expense (including reasonable attorneys' fees and disbursements), judgments,
fines, settlements and other amounts arising from any and all claims, demands,
actions, suits or proceedings, whether civil, criminal, administrative or
investigative, in which the Indemnitee was involved or may be involved, or
threatened to be involved, as a party or otherwise, arising out of or incidental
to the business of the Company, excluding liabilities to any Member, regardless
of whether the Indemnitee is or continues to be a Director, Officer, employee,
or agent of the Company, or a Liquidating Person at the time any such liability
or expense is paid or incurred, to the fullest extent permitted by the Act and
all other applicable laws.

         15.3 EXPENSES. Expenses incurred by an Indemnitee in defending any
claim, demand, action, suit or proceeding subject to Section 15.2 shall, from
time to time, be advanced by the Company prior to the final disposition of such
claim, demand, action, suit or proceeding upon receipt by the Company of an
undertaking by or on behalf of the Indemnitee to repay such amount if it shall
be determined that such Person is not entitled to be indemnified as authorized
in Section 15.2.

         15.4 INDEMNIFICATION RIGHTS NON-EXCLUSIVE. The indemnification provided
by Section 15.2 shall be in addition to any other rights to which those
indemnified may be entitled under any agreement, action of the Board of
Directors, vote of the Members, as a matter of law or equity or otherwise, both
as to action in the Indemnitee's capacity as an Officer,

                                                            AMENDED AND RESTATED

Director, employee, or agent of the Company or as a Liquidating Person and as to
any action in another capacity, and shall continue as to an Indemnitee who has
ceased to serve in such capacity and shall inure to the benefit of the heirs,
successors, assigns and administrators of the Indemnitee.

         15.5 ERRORS AND OMISSIONS INSURANCE. The Company may purchase and
maintain insurance, at the Company's expense, on behalf of the Directors and
Officers and such other Persons as the Directors shall determine, against any
liability that may be asserted against, or any expense that may be incurred by,
such Person in connection with the activities of the Company, regardless of
whether the Company would have the power to indemnify such Person against such
liability under the provisions of this Agreement.

         15.6 ASSETS OF THE COMPANY. Any indemnification pursuant to Section 
15.2 shall be satisfied solely out of the assets of the Company. No Member shall
be subject to personal liability or required to fund or to cause to be funded
any obligation by reason of these indemnification provisions.

         18.1 EXCHANGE OF INFORMATION AND NONDISCLOSURE. In furtherance of this
Agreement, or pursuant to the Ancillary Agreements the Members may from time to
time come into possession of certain information and data, including business
plans, fabrication techniques, processes, technology, financial information and
other compilations of information, which relate to the business of the Members.
Prior to the execution of this Agreement, each Initial Member has executed, and
each new Member shall sign and become a party to, the Member's Confidentiality
Agreement relating to such information.

         18.2 CONFIDENTIALITY AGREEMENTS FOR VISITORS AND EMPLOYEES. Any
employee, contractor, subcontractor or guest of TSMC, ADI, Altera or ISSI who
visit the Foundry ("Visitor") shall execute and deliver a copy of the
Confidentiality Agreement in the form of Exhibit C(1). Visitors shall not be
permitted to: make or compile any notes, documentation or other information, or
make any photographs, drawings, tapes, films or other graphic representations.
Each employee of the Company at the time of employment shall execute and deliver
a copy of the Employee Invention Assignment and Confidentiality Agreement in the
form of Exhibit C(2).

         18.3 THIRD PARTY REQUEST FOR INFORMATION. Except as otherwise provided
in this Agreement and except for private requests in the ordinary course of
business for non-Confidential Information relating to the Proven Products, a
Member shall immediately notify the other Members of any private or governmental
request for Confidential Information or any other information or documents
relating to the Proven Products or this Agreement. Each Member shall have the
right to participate in any other Member's response to any such request. In the
event that a Member receives any subpoena or other legal process requiring the
production of information, documents, data, work papers, reports, or other
materials relating to this Agreement, that Member shall:

                  18.3.1 give the other Members, if possible, the opportunity to
participate in quashing, modifying or otherwise responding to any compulsory
process in an appropriate and timely manner; and

                  18.3.2 cooperate fully with the other Member's efforts to
narrow the scope of any such compulsory process, to obtain a protective order
limiting the use or disclosure of the information sought, or in any other lawful
way to obtain continued protection of the Confidential Information.

Notwithstanding the foregoing, a private request to a Member from a third party
for Design Rules (as defined in the Purchase Agreement) and reliability results
may be disclosed without prior notice to the other Members if such third party
executes a Confidentiality Agreement in the form of Exhibit L to the Purchase
Agreement and the other Members are promptly provided with notice of the
disclosure after the disclosure is made.

         18.4 REPORTING LOSS, THEFT OR MISAPPROPRIATION. If any Member becomes
aware of the loss, theft or misappropriation of Confidential Information which

possession or control, it shall notify the other Members in writing within five
(5) days of its discovery of such loss, theft or misappropriation.

         18.5 BREACH OF CONFIDENTIALITY. Each Member acknowledges that a breach
of this Article 18 or a breach of either of the Confidentiality Agreements will
result in irreparable injury to the party whose Confidential Information has
been disclosed and such party shall be entitled to temporary, preliminary and
permanent injunctive relief or to a protective order for any threatened or
actual violation of the provisions of this Article. Each Member agrees and
consents to the entry of an injunction or protective order by any court of
competent jurisdiction upon a showing by the party whose Confidential
Information has been disclosed that its Confidential Information is being used
or disclosed contrary to the terms of this Article 18 or the Confidentiality
Agreements. The foregoing provisions are in addition to, and not in limitation
of, the remedies of specific performance, damages, and any other remedies at
law, in equity or otherwise that the Members may have upon breach. The Members
stipulate that the arbitration provisions of Article 20 shall not apply to any
temporary restraining order, preliminary injunctive relief or other provisional
remedy sought to prohibit a breach or threatened breach of the provisions of
this Article or the Confidentiality Agreements.

         19.1 EXECUTION AND DELIVERY. On or before the Effective Date, the
following documents were executed and delivered by the parties thereto, and the
Company executed and delivered each such document: the Confidentiality
Agreements, the Registration Rights Agreement, and the Assignments of the
Manufacturing Agreement, the Technology License and Assistance Agreement and the
Advanced Process Agreement.

         19.2 TERMINATION OF MANUFACTURING AGREEMENT; FUTURE PURCHASE AGREEMENT.
Following the expiration or termination of the Manufacturing Agreement (and
consequently, the termination of the Purchase Agreement), until the useful life
of the Foundry has ended, the Managing Members shall enter into the Future
Purchase Agreement, the form of which is attached hereto as Exhibit F, whereby
the Managing Members shall have the right and obligation to purchase the output
of the Foundry as provided for in the Future Purchase Agreement. Notwithstanding
the foregoing, the Members agree that if the Company constructs an additional
foundry on the Real Property, any rights or obligations to purchase the output
of such additional foundry shall be negotiated at that time and shall not be
covered by the provisions of the Purchase Agreement or the Future Purchase 
Agreement.

         20.1 NEGOTIATION BETWEEN EXECUTIVES. Each of the Members and the
Company shall attempt in good faith to resolve any dispute, controversy or claim
("Dispute")

   64
arising out of or relating to this Agreement promptly by negotiations between
executives who have authority to settle the Dispute. Any Member or the Company
may give the other Members and the Company written notice of any Dispute not
resolved in the normal course of business. Within twenty (20) days after
delivery of such a notice, executives of the Members and the Company involved in
the Dispute who have authority to settle the Dispute shall meet at a mutually
acceptable time and place, and thereafter as often as they reasonably deem
necessary, to attempt to resolve the Dispute. If the matter has not been
resolved within thirty (30) days after such notice, unless extended by the
agreement of the parties involved in the Dispute in writing (the "Negotiation
Period"), the matter shall be subject to mediation as provided in Section 20.2.
If a Member or the Company intends to be accompanied at a meeting by an
attorney, the other involved parties shall be given at least three (3) Business
Days' notice of such intention and may also be accompanied by an attorney. All
negotiations pursuant to this provision are confidential and shall be treated as
compromise and settlement negotiations for purpose of the United States Federal
Rules of Evidence and state rules of evidence.

         20.2 MEDIATION. Any Dispute not settled pursuant to Section 20.1 shall
be submitted to mediation administered by the American Arbitration Association
under its Commercial Mediation Rules (such mediation, "Mediation"), before
resorting to arbitration as hereinafter provided. The Mediation shall be
completed within forty-five (45) days of its initiation pursuant to the
Commercial Mediation Rules, unless all the parties involved in the Dispute
otherwise agree. Executives of all parties involved in the Dispute with
authority to resolve the Dispute shall participate in the Mediation. The
Mediation shall take place in San Jose, California. The parties shall attempt in
good faith to reach agreement on the appointment of a mediator. If they cannot
so agree, the mediator shall be appointed pursuant to the Commercial Mediation
Rules; provided, however, that the mediator appointed shall have a background in
the semiconductor industry. The parties involved in the Dispute shall each pay
their own expenses of Mediation, including attorney's fees, and shall share
equally the mediator's fees and expenses.

         20.3 CLAIMS SUBJECT TO ARBITRATION. Except as otherwise specified
below, any Dispute arising out of or relating to this Agreement, or the breach
or termination thereof, and not resolved pursuant to Section 20.1 or Section 
20.2 shall be resolved by binding arbitration in accordance with the Federal
Arbitration Act, 9 U.S.C. Sections 1 et seq. (the "FAA"), and the
Commercial Arbitration Rules and, where the amount in controversy exceeds
$1,000,000, the Supplementary Procedures for Large Complex Disputes, of the AAA
(collectively, the "Rules"). In the event of a conflict between the FAA and the
Rules, the Rules shall govern. In the event of a conflict between this Article
20 and the FAA or the Rules, the provisions of this Article 20 shall govern. A
court of competent jurisdiction, upon application from any party to the Dispute,
may relieve the parties of their duty to arbitrate Disputes in whole or in part,
or may stay any arbitration hereunder in whole or in part, if ongoing litigation
between one or more of the parties and a third party (or parties) involves
issues of fact or law common with those subject to arbitration hereunder and
there exists the possibility of inconsistent judgments if such relief is not
granted. Each party involved in a Dispute also reserves the right to file with a
court of competent jurisdiction an application for temporary or preliminary
injunctive relief, a protective order or other appropriate provisional remedy on
grounds that (a) the arbitration award to which the applicant may be entitled
may be rendered ineffectual in the absence of such relief; or (b) in the event
of a breach or threatened breach of Article 18 hereof or the Confidentiality
Agreements.

                  20.3.1 VENUE. The venue for such arbitration proceeding will
be San Jose, California.

                  20.3.2 SELECTION OF ARBITRATOR AND DETERMINATION OF
CONTROVERSIES.

                  20.3.2.1 Any Dispute subject to arbitration shall be submitted
to a single neutral arbitrator, who, unless otherwise agreed by all parties
involved in the Dispute, shall be a retired judge or other lawyer who is a
member of the arbitration panel of the Judicial Arbitration and Mediation
Service ("JAMS") or the national panel of arbitrators of the AAA and who has
substantial experience in the area of the Dispute. The parties involved in the
Dispute shall confer concerning the selection of the AAA or JAMS with the
objective of selecting one or the other within thirty (30) days of the
conclusion of the Mediation; provided, however, that if all parties to the
Dispute do not agree on one or the other within such thirty (30) day period, the
Dispute initially will be submitted simultaneously to both the AAA and JAMS for
the sole purpose of picking the arbitrator. If the parties to the Dispute select
the arbitrator from the JAMS panel, then the term "Rules" as used herein shall
mean the then-prevailing JAMS rules. The AAA (or JAMS, as the case may be)
simultaneously shall submit to each party involved in the Dispute an identical
list of five proposed qualified arbitrators drawn from the applicable panel of
commercial arbitrators. If the parties involved in the Dispute are unable to
agree upon an arbitrator within thirty (30) days from the date that the AAA (or
JAMS, as the case may be) submits such list to the parties involved in the
Dispute, then the AAA (or JAMS, as the case may be) shall simultaneously submit
to each party involved in the Dispute a second identical list of five additional
proposed qualified arbitrators drawn from the applicable panel of commercial
arbitrators. If for any reason, the appointment of an arbitrator cannot be made
from either list, the AAA (or JAMS, as the case may be) may make the appointment
from among other qualified members of the panel without the submission of
additional lists to the parties involved in the Dispute. If the Dispute is
initially submitted to both the AAA and JAMS for the purpose of picking the
arbitrator, then both the AAA and JAMS simultaneously shall submit to each party
lists of five proposed qualified arbitrators drawn from the applicable panel
(with each party receiving the identical list from AAA and the identical list
from JAMS), and if the parties are unable to agree upon an arbitrator within
thirty (30) days from the date that both the AAA and JAMS submit the first such
lists to each party, then the AAA and JAMS simultaneously shall submit to each
party second lists of five additional proposed qualified arbitrators (with each
party receiving an identical second list from AAA and an identical second list
from JAMS). If the parties for any reason are unable to select an arbitrator
from the first and second lists submitted by the AAA and JAMS, then a majority
of the parties shall select to arbitrate with either the AAA or JAMS, and the
arbitration organization so selected shall make the appointment from among other
qualified members of the arbitration panel of that organization without the
submission of additional lists to the parties. Where the parties have initially
submitted the Dispute to both the AAA and JAMS, then once an arbitrator has been
appointed, the arbitration proceeding will be terminated with the arbitration
organization that has not been selected and the parties shall equally share the
costs and fees of the arbitration organization so terminated. If for any reason
the parties to the Dispute have not selected an arbitrator within ninety (90)
days of the conclusion of the Mediation, then the arbitration shall be conducted
with the AAA. No matter how selected, the

arbitrator shall have no prior or existing affiliation or relationship with any
party involved in the Dispute or its counsel, and shall sign an oath of
impartiality upon appointment.

                  20.3.2.2 The parties involved in the Dispute shall be entitled
to obtain pre-hearing discovery through depositions and requests for the
inspection and copying of documents and other items upon reasonable notice and
to obtain the issuance of a subpoena duces tecum therefor in accordance with
applicable law, including without limitation 9 U.S.C. Section 7 and
(notwithstanding Section 1297.17 of the California Code of Civil Procedure)
Section 1283.05 of the California Code of Civil Procedure; provided that
depositions shall not be taken unless leave to do so is first granted by the
arbitrator. As between the parties involved in the Dispute, the arbitrator shall
have the power to enforce the rights, remedies, procedures, duties, liabilities
and obligations of discovery by the imposition of the same terms, conditions,
consequences, sanctions and penalties as may be imposed in like circumstances in
a civil action by a U.S. Federal court.

                  20.3.3 ARBITRATION AWARD AND JUDICIAL REVIEW. The arbitrator,
in deciding any Dispute, shall base his or her decision on the record and in
accordance with this Agreement and applicable law. In no event shall the
arbitrator make any ruling, finding or award that does not conform to the terms
and conditions of this Agreement, is not supported by the weight of the
evidence, or is contrary to statute, administrative regulations or established
judicial precedents. The arbitration award shall be a factually detailed,
reasoned opinion stating the arbitrator's findings of fact and conclusions of
law. Unless the arbitrator for good cause determines otherwise, the final award
shall include attorneys' fees, costs and expenses of the prevailing party,
including expert and non-expert witness fees and the prevailing party's share of
the administrative fee and the arbitrator's fees and expenses, if any.
Notwithstanding any other provisions of this Agreement, the arbitrator shall
have no jurisdiction to award damages in contravention of Article 21 hereof. The
arbitration award shall be subject to judicial review in accordance with 9
U.S.C. Sections 10-12; provided, however, that the arbitration award shall
also be vacated to the extent that the arbitrator exceeds his or her authority
as set forth in this Section 20.3.3, and, on balance, the party seeking vacation
of the award has been materially and adversely affected thereby. Judgment may be
entered on the award by the United States District Court in accordance with 9
U.S.C. Section 9.

                  20.3.4 DERIVATIVE ACTION. Pursuant to Section 20.3, a Member
may initiate and pursue in the right of the Company any Dispute arising out of
or relating to a transaction which is the subject matter of Section 2.10.2 or
Section 3.5.1. The parties to any such Dispute shall first attempt to resolve
the Dispute pursuant to Section 20.1 or 20.2.

                                  FORCE MAJEURE

         22.1 FORCE MAJEURE. Subject to the limitations set forth in Section 
22.4, should any Member be prevented from performing such Member's contractual
obligations under this Agreement due to the cause or causes of Force Majeure,
that Member shall not be liable to any other Member for any delay or failure of
performance caused by any Force Majeure events; nor shall that Member be deemed
to have committed an Event of Default hereunder. Notwithstanding the foregoing,
a Force Majeure event shall not excuse a Member's obligation to pay money.
However, a monetary obligation shall be suspended until cessation of such Force
Majeure event if,

                                                            AMENDED AND RESTATED

and only if, the Force Majeure event actually and directly renders physically
impossible a Member's payment of money due under this Agreement.

         22.2 NOTIFICATION. The Member prevented or delayed by a Force Majeure
event in the performance of any obligation hereunder shall promptly notify the
other Members of the occurrence of any Force Majeure event in writing by cable,
telex or telecopier.

         22.3 RESPONSE TO FORCE MAJEURE. Should the delay caused by any events
of Force Majeure continue for more than ninety (90) days, the Members shall
settle all questions of further performance of this Agreement through good faith
negotiations as soon as possible with the objective of restructuring the
relationship among them such that the effects of such events of Force Majeure
are minimized. If the Members do not agree in writing on a mutually acceptable
solution within six (6) months of a Member's request for such negotiations, the
Board of Directors shall have the authority to deem the Member subject to the
Force Majeure event to have committed an Event of Default at which time, the
Member shall become a Terminated Member, without necessity for a vote of the
Members, and, without limitation, shall be subject to the provisions of Sections
10.3 through 10.7, inclusive.

         22.4 LIMITATIONS ON APPLICABILITY OF FORCE MAJEURE. This Article 22
shall be void and inapplicable to any Member (i) if such Member fails to use
reasonable diligence to remedy any Force Majeure event that prevents or delays
that Member's performance hereunder by continuously pursuing such actions as
that Member reasonably can take under the circumstances; and (ii) in the event
of a strike, lockout or other labor disruption, if the Member is found by the
National Labor Relations Board or other governmental agency having jurisdiction
to have caused such strike, lockout or labor disruption or if such Member
refuses to enter into bargaining with respect to such strike, lockout or labor
disruption.

         23.1 SEVERABILITY. If any provision of this Agreement is, or becomes or
is deemed invalid, illegal or unenforceable in any jurisdiction, such provision
shall be deemed amended to conform to applicable laws so as to be valid and
enforceable or, if it cannot be so amended without materially altering the
intention of the Members, it shall be stricken and the remainder of this
Agreement shall remain in full force and effect.

         23.2 NEUTRAL INTERPRETATION; WAIVER. Each party hereto has received
independent legal advice from its attorneys with respect to the advisability of
executing this Agreement and the meaning of the provisions hereof. Each party
hereto waives any real, apparent, possible or inchoate conflict in connection
with, arising out of or resulting from the representation of any Member and its
Affiliates, and the Company by the same law firm. The provisions of this
Agreement shall be construed as to their fair meaning, and not for or against
any party hereto based upon any attribution to such party as the source of the
language in question.

Agreement, the Ancillary Agreements, the Executive Incentive Plan and that
certain letter from TSMC Taiwan to the Members dated as of the Effective Date

Members, and supersede any and all prior or contemporaneous negotiations,
correspondence, understandings, representations, warranties and agreements
between the Members, written or oral, respecting the subject matter hereof or
thereof. Other than as contained herein and as provided in Section 23.23, in the
Ancillary Agreements or in the Letter of Assurances, no representation,
warranty, statement, or condition is binding on the parties hereto or thereto,
or has any force or effect whatsoever.

effective unless and until made in writing and signed by each party hereto. No
waiver, forbearance or failure by any party hereto of its right to enforce any

waiver by such party of compliance with any provision.

party hereto and shall take such further action and shall execute and deliver

other party to exercise good faith efforts to correct any such drafting errors.

other jurisdiction to compel any sale or appraisal of Company assets or sale or
appraisal of a deceased Member's interest therein, are hereby irrevocably waived
and dispensed with. The Interest of a deceased Member shall be subject to the
provisions of this Agreement.

California, agrees, subject to the provisions of Article 20 and Article 21, that
any action, suit or proceeding by or among the Members (or any of them) or the
Company and any Member may be brought in any such court sitting in San Jose,
California and waives any objection which the Member may now or hereafter have

hereby irrevocably designates, appoints and empowers the Secretary of State of
California to receive for and on behalf of such party service of process in the
State of California and further irrevocably consents to the service of process
outside of the territorial jurisdiction of said courts by mailing copies thereof

party hereto further agrees that final judgment against it in any such action or

amount of such judgment.

without limitation those relating to the valuation of a Member's Interest or
adjustments in Percentage Interests, have been negotiated by the parties hereto
at arm's-length, and each party affirms that all such provisions are fair, just
and equitable. Without limiting the generality of the foregoing, the provisions
of Sections 3.3, 3.5.4, 8.1.4, 8.2.4, 10.3, 10.5 and 22.3 reflect the parties'
best estimates of liquidated compensatory damages and do not constitute a

         23.20 AUTHORIZED REPRESENTATIVES. Until changed by a party hereto by
written notice to each of the other parties, the following individuals, and only
such individuals, are authorized to act on behalf of the party so designating

COMPANY AND THE MEMBERS HEREBY EXPRESSLY WAIVE ANY SUCH CONFLICT OF INTEREST
WITH RESPECT TO ANY SUCH DUAL REPRESENTATION RELATIVE TO THE NEGOTIATION AND
EXECUTION OF THIS AGREEMENT AND THE ANCILLARY AGREEMENTS.

         23.23 AMENDMENT AND RESTATEMENT. This Agreement amends, restates and
supercedes the Original Agreement, and makes certain non-material changes for

or Receiving Party's Representatives of the Confidential Information.

         8.       REMEDIES

                  Receiving Party also acknowledges that money damages would be
both incalculable and an insufficient remedy for any breach of this Agreement by
a Receiving Party or a Receiving Party's Representatives, and that such breach
would cause Company irreparable harm. In addition to all other remedies, the
Company will be entitled to specific performance and injunctive or other
equitable relief as a remedy for any such breach, and the breaching party agrees
to waive any requirement of receiving or posting any bond in connection with
such remedy. Receiving Party agrees and consents to the entry of a preliminary
injunction or protective order by any court of competent jurisdiction upon a
showing by the Company that its Confidential Information is being used or
disclosed contrary to the provisions of this Agreement. The arbitration
provisions of Section 12 shall not apply to any temporary restraining order,
preliminary injunctive relief or other provisional remedy sought to prohibit a
breach or threatened breach of the provisions of this Agreement.

Party of Company's Confidential Information or any of its patents, copyrights,
trademarks, or applications therefor. All proprietary rights, including but not
limited to patent rights and trade secrets, in and to the Confidential
Information shall remain Company's property.

                  It is understood and agreed that no failure or delay by the
Company in exercising any right, power or privilege hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise thereof preclude any or
further exercise or the exercise of any right, power or privilege hereunder.

         11.      SEVERABILITY

                  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision

of authorship, derivative works, formulas, processes, techniques, know-how,
ideas, concepts, compositions of matter, computer software programs, databases,
mask works and trade secrets ("Inventions") that I make, conceive, first reduce
to practice or create, either alone or jointly with others, during the period of
my employment with the Company (the "Employment Period"), whether or not in the
course of such employment, and whether or not such Inventions are patentable,
copyrightable or protectible as trade secrets or mask works. Listed on Schedule
A hereto are Inventions I have made, conceived, first reduced to practice or
created, either alone or jointly with others, before the Effective Date, which I
consider to remain unaffected by the terms and provisions of this Agreement.

         3. WORKS MADE FOR HIRE; ASSIGNMENT OF INVENTIONS. I acknowledge and
agree that any copyrightable works prepared by me, either alone or jointly with
others, within the scope of my employment during the Employment Period are
"works made for hire" under the United States Copyright Act (17 U.S.C.
Sections 101-810) and that the Company will be considered the author and
owner of such copyrightable works. In the event that any such copyrightable
works are not deemed to be "works made for hire," I hereby irrevocably assign
all of my right, title and interest in and to such copyrightable works to the
Company. I agree that all Inventions that (a) are developed using equipment,
supplies, facilities or trade secrets of the Company, (b) result from work
performed by me for the Company during the Employment Period, or (c) relate to
the Company's business or current or anticipated research and development, will
be the sole and exclusive property of the Company and are hereby irrevocably
assigned by me to the Company.

         4. ASSIGNMENT OF OTHER RIGHTS. In addition to the foregoing assignment
of Inventions to the Company, I hereby irrevocably transfer and assign to the
Company all worldwide patents, patent applications, copyrights, mask works,
trade secrets and other intellectual property rights that I may have in any
Invention. I also hereby forever waive and agree never to assert any and all
Moral Rights (as defined below) I may have in or with respect to any Invention,
even after termination of my work on behalf of the Company. "Moral Rights" mean


                                                   EMPLOYEE INVENTION ASSIGNMENT
                                                   AND CONFIDENTIALITY AGREEMENT
   88
any rights to claim authorship of a work, to object to or prevent any distortion
or other modification of a work, or to withdraw from circulation or control the
publication or distribution of a work, and any similar right, existing under
judicial or statutory law of any country in the world, or under any treaty,
regardless of whether or not such right is denominated or generally referred to
as a "moral right."

         5. LABOR CODE 2870 NOTICE. I have been notified and understand that the
provisions of Sections 3 and 4 of this Agreement do not apply to any Invention
that qualifies fully under the provisions of Section 2870 of the California
Labor Code, which states as follows:

ANY PROVISION IN AN EMPLOYMENT AGREEMENT WHICH PROVIDES THAT AN EMPLOYEE SHALL
ASSIGN, OR OFFER TO ASSIGN, ANY OF HIS OR HER RIGHTS IN AN INVENTION TO HIS OR
HER EMPLOYER SHALL NOT APPLY TO AN INVENTION THAT THE EMPLOYEE DEVELOPED
ENTIRELY ON HIS OR HER OWN TIME WITHOUT USING THE EMPLOYER'S EQUIPMENT,
SUPPLIES, FACILITIES, OR TRADE SECRET INFORMATION EXCEPT FOR THOSE INVENTIONS
THAT EITHER: (1) RELATE AT THE TIME OF CONCEPTION OR REDUCTION TO PRACTICE OF
THE INVENTION TO THE EMPLOYER'S BUSINESS, OR ACTUALLY OR DEMONSTRABLY
ANTICIPATED RESEARCH OR DEVELOPMENT OF THE EMPLOYER, OR (2) RESULT FROM ANY WORK
PERFORMED BY THE EMPLOYEE FOR THE EMPLOYER. TO THE EXTENT A PROVISION IN AN
EMPLOYMENT AGREEMENT PURPORTS TO REQUIRE AN EMPLOYEE TO ASSIGN AN INVENTION
OTHERWISE EXCLUDED FROM BEING REQUIRED TO BE ASSIGNED UNDER CALIFORNIA LABOR
CODE SECTION 2870(a), THE PROVISION IS AGAINST THE PUBLIC POLICY OF THIS STATE
AND IS UNENFORCEABLE.

         6. ASSISTANCE. I agree to assist the Company in every proper way to
obtain for the Company and enforce patents, copyrights, mask work rights, trade
secret rights and all other legal protections for the Company's Inventions in
any and all countries. I will execute any documents that the Company may
reasonably request for use in obtaining or enforcing such patents, copyrights,
mask work rights, trade secrets and all other legal protections. My obligations
under this Section 6 will be in consideration of my employment with the Company
during the Employment Period and will continue beyond the termination of the
Employment Period, provided that the Company will compensate me at a reasonable
rate for time or expenses actually spent by me at the Company's request after
such termination on such assistance, which reasonable rate will be determined in
light of my hourly rate or salary in effect prior to the termination of the
Employment Period. I appoint the Secretary of the Company as my attorney-in-fact
to execute documents on my behalf for this purpose.

         7. PROPRIETARY INFORMATION. I understand and agree that my employment
by the Company creates a relationship of confidence and trust with respect to
any information of a confidential or secret nature that may be disclosed to me
by the Company that relates to the business of the Company or to the business of
any parent, subsidiary, affiliate, customer or supplier of the Company or any
other party with whom the Company agrees to hold information of such party in
confidence ("Proprietary Information"). Such Proprietary Information includes


                                                   EMPLOYEE INVENTION ASSIGNMENT
                                                   AND CONFIDENTIALITY AGREEMENT

   89
but is not limited to Inventions, marketing plans, product plans, business
strategies, financial information, forecasts, personnel information and customer
lists.

         8. CONFIDENTIALITY. At all times, both during the Employment Period and
after its termination, I will keep and hold all such Proprietary Information in
strict confidence and trust, and I will not use or disclose any of such
Proprietary Information without the prior written consent of the Company, except
as may be necessary (a) to perform my duties as an employee of the Company for
the benefit of the Company, or (b) to comply with a court order to disclose such
Proprietary Information. Upon termination of my employment with the Company, I
will promptly deliver to the Company all documents and materials of any nature
pertaining to my work with the Company and I will not take with me any documents
or materials or copies thereof containing any Proprietary Information.

         9. NO BREACH OF PRIOR AGREEMENT. I represent that my performance of all
the terms of this Agreement and my duties as an employee of the Company will not
breach any invention assignment, proprietary information or similar agreement
with any former employer or other party. I represent that I will not bring with
me to the Company or use in the performance of my duties for the Company any
documents or materials of a former employer that are not generally available to
the public or have not been legally transferred to the Company.

         10. DUTY NOT TO COMPETE. I understand that my employment with the
Company requires my undivided attention and effort. As a result, during the
Employment Period, I will not, without the Company's express written consent,
engage in any employment or business other than for the Company, or invest in or
assist in any manner any business which directly or indirectly competes with the
business or future business plans of the Company.

         11. NOTIFICATION. I hereby authorize the Company to notify my future
employers of the terms of this Agreement and my responsibilities hereunder.

         12. NON-SOLICITATION. During the Employment Period, I will not directly
or indirectly solicit or take away supplies, customers, employees or consultants
of the Company for my own benefit or for the benefit of any other party. I
understand that this Agreement does not prevent me from soliciting supplies,
customers, employees and consultants for the Company during the Employment
Period. To the extent permitted by law, I will not directly or indirectly
solicit or take away for a period of one (1) year after termination of the
Employment Period supplies, customers, employees or consultants of the Company
for my own benefit or for the benefit of any other party.

         13. NAME AND LIKENESS RIGHTS, ETC. I hereby authorize the Company to
use, reuse, and to grant others the right to use and reuse, my name, photograph,
likeness (including caricature), voice, and biographical information, and any
reproduction or simulation thereof, in any media now known or hereafter
developed (including but not limited to film, video and digital or other
electronic media), both during and after my employment, for whatever purposes
the Company deems necessary. I understand and agree that I will receive no
compensation whatsoever for any such use or reuse.

         14. INJUNCTIVE RELIEF. I understand that in the event of a breach or
threatened breach of this Agreement by me the Company may suffer irreparable
harm and will therefore be entitled to injunctive relief to enforce this
Agreement or any of its provisions, without prejudice to any other rights and
remedies that the Company may have for a breach of this Agreement.

         15. GOVERNING LAW; SEVERABILITY. This Agreement will be governed and
interpreted in accordance with the internal laws of the State of Delaware,
without regard to or application of choice of law rules or principles. In the
event that any provision of this Agreement is found by a court, arbitrator or
other tribunal to be illegal, invalid or unenforceable, then such provision
shall not be voided, but shall be enforced to the maximum extent permissible
under applicable law, and the remainder of this Agreement shall remain in full
force and effect.

         16. NO DUTY TO EMPLOY. I understand that this Agreement does not
constitute a contract of employment or obligate the Company to employ me for any
stated period of time and this Agreement does not interfere in any way with any
right the Company have to terminate my employment at any time, with or without
cause. This Agreement shall be effective as of the Effective Date.

         17. COUNTERPARTS. This Agreement may be executed as separate
counterparts, each of which shall be an original and all of which taken together
shall constitute one and the same Agreement.

         This Purchase Agreement ("Agreement") is entered into as of
____________ (the "Effective Date"), by and among WaferTech, LLC, a Delaware
limited liability company, as seller hereunder ("Seller"), and TSMC Development,
Inc. ("TSMC"), a Delaware corporation, Analog Devices, Inc. ("ADI"), a
Massachusetts corporation; Altera Corporation ("Altera"), a California
corporation; and Integrated Silicon Solutions, Inc. ("ISSI"), a Delaware
corporation, as buyers hereunder (each buyer hereunder, a "Buyer," TSMC, ADI,
Altera and ISSI each is sometimes referred to as an "Initial" Buyer, each Buyer
other than TSMC is sometimes referred to as a "Regular" Buyer). Each party
hereto is sometimes referred to as a "Party".

                                R E C I T A L S:

         This Agreement is made with reference to the following facts and
circumstances:

         B. The Initial Buyers are members of Seller under its Limited Liability
Company Agreement, dated June __, 1996 (such agreement, the "LLC Agreement," and
such date, the "LLC Agreement Date"). Seller built, owns and operates a
semiconductor wafer fabrication plant in Camas, Washington (such plant, the
"Foundry"). The Foundry provides foundry services for the manufacture of
integrated circuits in wafer form.

         C. Following the commencement of production at the Foundry and until
the Effective Date of this Agreement, the Foundry sold its entire output to
Taiwan Semiconductor Manufacturing Co., Ltd. ("TSMC Taiwan"), of which TSMC is a
second-tier subsidiary. Such sale occurred pursuant to the Manufacturing
Agreement, dated as of February 16, 1996, originally entered into between TSMC
Taiwan, as buyer, and TSMC, as supplier. Supplier's interest under the
Manufacturing Agreement was assigned by TSMC to Seller pursuant to the
Assignment and Assumption dated as of the LLC Agreement Date. The Manufacturing
Agreement expired or terminated on or before the Effective Date.



         D. During the term of the Manufacturing Agreement, TSMC Taiwan in turn
resold the output to ADI, Altera, ISSI, and other customers of TSMC Taiwan.
Sales to ADI, Altera, and ISSI occurred pursuant to that certain Purchase
Agreement, dated as of the LLC Agreement Date, among TSMC Taiwan, ADI, Altera,
and ISSI (the "Original Purchase Agreement"). The


                                                       FUTURE PURCHASE AGREEMENT

Original Purchase Agreement expired or terminated with the expiration or
termination of the Manufacturing Agreement.

         E. Seller and the Initial Buyers, in accordance with the LLC Agreement,
are entering into this Agreement:

                  (1) to provide for the direct sale of Foundry output (a) to
         the Initial Buyers and (b) to any other Persons that (i) are admitted
         to membership in Seller in accordance with the LLC Agreement after the
         Effective Date and (ii) become Buyers in accordance with the terms
         below; and

                  (2) to define the purchase obligations and rights of Buyers
         with respect to Foundry output for the duration of the Foundry's
         remaining useful life.

the terms, covenants and conditions contained herein, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Parties agree as follows:

               WAFER SUPPLY; FOUNDRY OUTPUT RIGHTS AND OBLIGATIONS

         3.1 MANUFACTURING CAPABILITY. During the Term, the Calculated Installed
Capacity of the Foundry is anticipated to be as shown in the initial Production
Plan attached hereto as Exhibit "E". Seller shall exert commercially reasonable
efforts to maintain production in accordance with the schedule set forth on
Exhibit "E" (as Exhibit "E" is updated from time to time); provided, however,
there is no guarantee that actual Foundry production will equal or exceed the
projected production levels or the Calculated Installed Capacity set forth in
the initial or any subsequent Production Plans, either at the time indicated
therein or at any time.

         3.2  PRODUCTION AVAILABILITY.

                  3.2.1 During the Term, Seller shall be obligated to make
available to each Buyer at any given time a quantity of Products no less than
the Buyer's Elected Proportion of Calculated Installed Capacity in effect at
such time, provided that the Elected Proportion is between the Buyer's Minimum
Purchase Share and Maximum Purchase Share at such time.

                  3.2.2 During the Term, each Buyer shall have the right to
purchase Products in amounts up to its Maximum Purchase Share of Calculated
Installed Capacity in accordance with Subsection 3.3.1 and shall be obligated to
purchase only its Minimum Purchase Share of Calculated Installed Capacity in
accordance with Subsection 3.3.2.

                  3.2.3 In the event that Seller cannot provide a Buyer with the
quantity of Products set forth in the Buyer's Purchase Orders accepted by Seller
for any given Quarter during the Term (a "Quarterly Order Deficit") due to
inability or failure of Seller to deliver to the Buyer those Products that the
Buyer has ordered or due to Force Majeure, then the following shall apply: (a)
where Seller has been unable or fails to supply the Buyer for reasons other than
Force Majeure, Seller shall not be deemed to be in default hereunder so long as
Seller can make up the Quarterly

   113
Order Deficit in the following Quarter; and (b) where Seller's failure to fill
the Buyer's Purchase Orders is due to Force Majeure, the Buyer shall be excused
from its purchase obligations to the extent that the Buyer placed orders for
Products in amounts equal to or greater than the units of Products that Seller
is able to deliver for the Quarter in question, and Seller shall only invoice
the Buyer for the actual number of units Seller is able to ship for the Quarter
in question. With respect to clause (a) of this Subsection 3.2.3, to the extent
that Seller is unable to make up the Buyer's Quarterly Order Deficit in the
succeeding Quarter, Seller shall be responsible for any damages sustained by
such Buyer (or its customer), subject to the limitation on damages set forth in
Article 10 below. With respect to clause (b) of this Subsection 3.2.3, Seller
shall have no liability or obligation whatsoever to an affected Buyer where
Seller's inability to fill the Buyer's Purchase Order is due to an event of
Force Majeure.

                  3.2.4 As used in this Article 3, "Quarter" refers to a Quarter
covered (or partially covered) by a Buyer's six (6) Month forecast described in
Section 4.1.1 or 4.1.2.

         3.3  BUYER'S PURCHASE RIGHTS AND OBLIGATIONS DURING THE TERM:

                  3.3.1 Each Buyer shall have the right to purchase a maximum
percentage of Calculated Installed Capacity in any given Quarter determined by
multiplying such Calculated Installed Capacity as shown in the applicable
Production Plan times the Buyer's respective Maximum Purchase Share; and

                  3.3.2 Each Buyer shall have the obligation to purchase a
minimum percentage of Calculated Installed Capacity in any given Quarter
determined by multiplying such Calculated Installed Capacity as shown in the
applicable Production Plan times the Buyer's Minimum Purchase Share. In each
Quarter, unless the applicable Buyer and Seller otherwise agree, a Buyer's
minimum purchase obligation is subject to the following limitation: a Buyer's
minimum purchase obligation in any given Month may not deviate more than ***
from the preceding Month's purchase obligation, unless Month-to-Month percentage
deviations shown in the applicable Production Plan exceed ***, in which case a
Buyer's minimum purchase obligation in any given Month may not deviate more than
the Month-to- Month percentage deviation shown in the applicable Production
Plan. If a Buyer requests an increase in the Month-to-Month *** percentage
deviation, Seller agrees to reasonably negotiate such increase with such Buyer
in good faith, provided, however, that each Buyer recognizes that Seller's
flexibility in negotiating an increase in the Month-to-Month *** percentage
deviation may be limited by commitments to other Buyers and Seller's other
customers.

                  3.3.3 A Buyer's purchase of Risk Wafers, Test Wafers, and
Proven Products shall be taken into account for purposes of (a) the Buyer's
satisfying its minimum purchase obligation under Subsection 3.3.2 and (b)

   114
                  3.4.1 During each Quarter of the Term, each Buyer agrees that
it shall purchase Products from Seller in accordance with Subsection 3.3.2. If
in any Quarter during the Term a Buyer (a "Defaulting Buyer") is unable to
purchase the Products in accordance with Subsection 3.3.2 (the "Unused Minimum
Purchase Allocation"), such Defaulting Buyer shall give Seller and all other
Buyers (each such other Buyer, a "Non-Defaulting Buyer") written notice (a "UMPA
Notice") no later than ninety (90) days before the date that the Products in
question are to begin manufacture in accordance with the Defaulting Buyer's six
(6) Month rolling forecast. Each Non-Defaulting Buyer shall have a right of
first refusal to take the Unused Minimum Purchase Allocation, provided it
exercises such right by written notice to the Defaulting Buyer and the other
Non-Defaulting Buyers within thirty (30) days following receipt of the
Defaulting Buyer's written notice (the "RFR Deadline"). The apportionment of the
Unused Minimum Purchase Allocation among the Non-Defaulting Buyers electing to
take any part of it shall be determined by the method set forth in Exhibit "J"
hereto, unless the Non-Defaulting Buyers agree to another procedure at the time.
If the Non- Defaulting Buyers exercise their rights of first refusal, then the
Defaulting Buyer shall be excused from any Bill-Back Charges (as defined below)
applicable to that portion of the Unused Minimum Purchase Allocation that the
Non-Defaulting Buyers elect to take; subject, however, to the last sentence of
this Subsection 3.4.1. If the Non-Defaulting Buyers elect not to take (or fail
timely to elect) any part of the Unused Minimum Purchase Allocation, then the
Defaulting Buyer shall have no later than sixty (60) days following delivery of
its UMPA Notice to identify in writing third parties ready, willing and able to
purchase from Seller the unelected part of the Unused Minimum Purchase
Allocation. So long as (a) Seller approves such third parties or any other third
parties (collectively, "Such Third Parties"), which approval shall not be
unreasonably withheld or delayed (provided, that in no event shall Such Third
Parties be Prohibited Persons, (b) Such Third Parties purchase all of the
unelected part of the Unused Minimum Purchase Allocation within sixty (60) days
after the date that the Defaulting Buyer identifies Such Third Parties to Seller
in writing, and (c) Such Third Parties pay the invoice price in full to Seller
within thirty-five (35) days after the date of invoice, then the Defaulting
Buyer shall be exonerated from any Bill-Back Charges applicable to the Unused
Minimum Purchase Allocation. A Buyer's take-or-pay obligation shall be measured
on a Quarter-by-Quarter basis; accordingly, for a Defaulting Buyer to avoid
Bill-Back Charges applicable to a particular Quarter's Unused Minimum Purchase
Allocation, either the Non-Defaulting Parties or Such Third Parties must have
committed to purchase the Defaulting Buyer's Unused Minimum Purchase Allocation
during the Quarter in which the Defaulting Buyer is unable to purchase Products
in accordance with Subsection 3.4.2.

                  3.4.2 If any part of the Unused Minimum Purchase Allocation
(a) is not taken by the Non-Defaulting Buyers in accordance with Subsection
3.4.1 and (b) (i) is not sold to third parties or (ii) is not paid for by
purchasing third parties in accordance with that Subsection, then the Defaulting
Buyer shall compensate Seller for such part of the Unused Minimum Purchase
Allocation at the full price for the Products in question, less any avoided
costs (the "Bill-Back Charge"). Seller shall invoice any Bill-Back Charges once
each Quarter during the Term, and within 30 days following the end of the Term
by lapse of time or otherwise. Any Defaulting Buyer shall pay the Bill-Back
Charge within thirty (30) days after the date of invoice (the "Payment Date").
Any Bill-Back Charge not received by Seller within thirty-five (35) days after

the date of invoice shall bear interest from the Payment Date until paid in full
by the Defaulting Buyer to Seller at the annual rate equal to 5% above the prime
or reference rate for commercial borrowing announced by Bank of America N.T. &
S.A., as such rate changes from time-to-time; provided, however, that in no
event shall such interest rate exceed the highest rate permissible under
applicable law. For the purpose of computing the Bill-Back Charge, the maximum
Calculated Installed Capacity shall not be deemed to exceed *** Wafer
Equivalents per month.

                  3.4.3 The provisions of Sections 3.4.1 and 3.4.2 shall be
Seller's sole remedy under this Agreement for any failure by a Buyer to purchase
its minimum quantities of Calculated Installed Capacity in any Quarter as set
forth in Subsection 3.3.2.


                                    ARTICLE 4
                      PRODUCTION PLANNING AND QUALIFICATION

         4.1  FORECASTS.

                  4.1.1 Concurrent with the execution and delivery hereof (or
promptly thereafter) in the case of the first Month of the Term and no later
than ten (10) Business Days before each succeeding Month of the Term, each
Regular Buyer shall provide Seller and TSMC in writing with a six- (6-) Month
rolling forecast of the Buyer's requirements for Products, with Product-mix
shown by Process and by geometry. Concurrent with the execution and delivery
hereof (or promptly thereafter) in the case of the first Month of the Term and
no later than the first Business Day of each succeeding Month of the Term, TSMC
shall provide Seller in writing with a six- (6-) Month rolling forecast of
TSMC's requirements for Products, with Product-mix shown by Process and
geometry. (Each Buyer's Product requirements at any given time as a proportion
of Calculated Installed Capacity at such time is referred to as the Buyer's
"Elected Proportion" for such time.) The first twelve (12) weeks of such
forecast shall be firm with respect to the quantity of Products to be purchased
or ordered within said period. If Seller's standard production lead time for a
particular Process or Product exceeds twelve (12) weeks, the Buyer's forecast
with respect to such Process or Product shall be firm for Seller's standard
production lead time plus two weeks.

                  4.1.2 Unless the Parties otherwise agree, the linear rate
deviation for each Regular Buyer's forecast for a given Month shall be *** of
the preceding Month forecast, unless Month-to-Month percentage deviations shown
in the applicable Production Plan exceed ***, in which case such Buyer's monthly
forecast may not deviate more than the Month-to- Month percentage deviation
shown in the applicable Production Plan. The foregoing linear rate deviation
applicable to a Regular Buyer's monthly forecast relates to the overall quantity
of Products set forth in the forecast and not to any one Process or to any
specific Product. If a Regular Buyer requests an increase in the Month-to-Month

percentage deviation, Seller agrees to reasonably negotiate such increase
with such Buyer in good faith, provided, however, that each Regular Buyer
recognizes that Seller's flexibility in negotiating an increase in the
Month-to-Month *** percentage deviation may be limited by commitments to other
Buyers and Seller's other customers.

         4.2  PRODUCTION QUALIFICATION.

                  4.2.1 Seller shall advise the Buyers concerning each Process
loaded or to be loaded at the Foundry for use in the manufacture of Products.
Seller then shall engage in Process Qualification for each Process not already a
Qualified Process. Once Seller has determined, in its reasonable judgement, that
a Process has achieved Process Qualification, such Process shall be a Qualified
Process. Seller shall promptly notify the Buyers when a Process becomes a
Qualified Process.

                  4.2.2 For each Product a Buyer desires to order, Seller shall
furnish Design Rules for the applicable Process, which shall be deemed attached
hereto as Exhibit "F". For each Product a Buyer desires to order, Seller and the
Buyer who intends to order the Product in question (the "Relevant Buyer") shall
further agree to a Product Qualification Plan. Once Seller and the Relevant
Buyer have agreed to a Product Qualification Plan, it shall be reduced to
writing and signed by Seller and the Relevant Buyer and shall be deemed to be
attached hereto as Exhibit "B". Seller and the Relevant Buyer also shall agree
to the Quality and Reliability Specifications, which shall be reduced to writing
and signed by Seller and the Relevant Buyer and shall be deemed to be attached
hereto as Exhibit "C".

                  4.2.3 Upon a Buyer's request, Seller shall designate a mask
vendor, to whom the Buyer (or its customer) shall provide device database tapes
and to whom Seller shall provide mask alignment and test structure databases, or
the Buyer (or its customer) will provide mask sets or portions thereof. Each
Buyer shall bear all costs and expenses of producing the mask sets necessary for
the manufacture of Products it orders under this Agreement.

                  4.2.4 Using a Buyer's (or its customer's) mask sets and the
Design Rules, Seller shall perform one or more Qual Lot Runs. Seller will
provide the Buyer with such amount of Test Wafers produced in such Qual Lot Runs
as such Buyer may require for its qualification at the purchase prices specified
in the Pricing Schedule. Within ninety (90) days following receipt of the Test
Wafers, the Buyer shall inform Seller in writing of whether or not such Test
Wafers meet the applicable Quality and Reliability Specifications, and if
notification is in the affirmative, full qualification for that Product is
completed. If Seller does not receive notification from the Buyer during the
time period specified in the preceding sentence, full qualification for that
Product shall be deemed accomplished. In the event that the Test Wafers do not
meet the Quality and Reliability Specifications, Seller and the Relevant Buyers
will work together in good faith to achieve full qualification for that Product.
The successful completion of the procedures outlined in Subsections 4.2.1
through 4.2.4, inclusive, is herein referred to as "Production Qualification".

                  4.2.5 Prior to the completion of full Production Qualification
for each Product, a Buyer may, by giving at least five (5) Business Days' notice
to Seller, terminate the production of any Test Wafers specified in Subsection

completion of the Process steps at which such Test Wafers or Risk Wafers reside
at the time Seller receives such notice. The terminating Buyer shall pay Seller
for all the Test Wafers or Risk Wafers so affected, and the prices for such Test
Wafers or Risk Wafers shall be the respective purchase prices specified in the
Pricing Schedule, equitably prorated based on the completed stage of production.

                  4.2.6 Once Production Qualification has been achieved for a
Product, such Product is a Proven Product, and Seller will produce that Proven
Product pursuant to Purchase Orders issued by Buyers and accepted by Seller
under Section 6.1 below.

                                    ARTICLE 5
               OTHER AGREEMENTS RELATING TO PRODUCTION AND SUPPLY

         5.1 QUANTITY REQUIREMENT. Subject to the Buyers' Maximum Purchase
Shares, Seller agrees to use commercially reasonable efforts to meet all the
quantity requirements of the Buyers for Products.

         5.2 ACCELERATE SUPPLY. It is anticipated that from time to time there
may be instances where an accelerated lead and cycle time is required to serve
the needs of a Buyer, and in such instances, Seller shall, upon mutually agreed
upon terms and conditions, use commercially reasonable efforts to accelerate the
schedule of production for Proven Products or Risk Wafers and/or increase the
manufacturing volume in order to meet that Buyer's needs.

         5.3 MODIFICATIONS TO EXISTING PROCESSES OR SPECIFICATIONS. If a Buyer
desires that Seller make modifications to a Qualified Process or to the Quality
and Reliability Specifications, such Buyer shall give Seller written notice
thereof, and within a reasonable amount of time after Seller's receipt of
Buyer's notice, Seller shall notify the Buyer in writing of any additional costs
associated with making such modifications (including, without limitation,
retooling costs), any adjustments in price, production, delivery schedule, and
any other terms and conditions of this Agreement that are necessary to make such
modifications (collectively, the "Modification Costs"). Within thirty (30) days
of its receipt of Seller's written notification of any such Modification Costs,
such Buyer shall either agree in writing to accept the obligation to pay Seller
any such Modification Costs or the Buyer may, in the exercise of its sole and
absolute discretion, withdraw its request that such modifications be made.
Seller shall not incur any Modification Costs on behalf of a Buyer unless and
until Seller has received Buyer's written agreement to pay the Modification
Costs. In addition to the foregoing requirement, any such requested
modifications must be acceptable to Seller and further must pass the Production
Qualifications procedures set forth in Section 4.2. If a requested modification
is unacceptable to Seller, or if it fails to pass the qualifications procedures
set out in Section 4.2, then Seller will continue to manufacture the Proven
Product in question in accordance with the existing Qualified Process and/or the
existing Quality and Reliability Specifications, in which event the notifying
Buyer shall be obligated to continue to purchase such Proven Product as so
manufactured. Once a Buyer has agreed to pay Modification Costs, such Buyer
shall pay to Seller all such Modification Costs within thirty (30)


                                       14

   118
days of Seller's invoice therefor. If Seller does not receive full payment of
Modification Costs within thirty-five (35) days after the date of invoice, the
invoice price shall bear interest from the date of invoice until paid in full at
the annual rate equal to 5% above the prime or reference rate for commercial
borrowing announced by Bank of America N.T. & S.A., as such rate changes from
time-to-time; provided, however, that in no event shall such interest rate
exceed the highest rate permissible under applicable law.

         5.4 ADDITIONS OR SUBSTITUTIONS OF PRODUCTS. If a Buyer desires that
Seller add or substitute a similar Product type using a Qualified Process (i.e.,
one that has not been assigned a current product model number) such Buyer shall
give Seller written notice thereof. Within a reasonable amount of time after
Seller's receipt of a Buyer's notice, Seller shall notify the Buyer in writing
of any additional cost associated with adding or substituting a similar Product
type (the "Additional Costs"). Within thirty (30) days of its receipt of
Seller's written notification of Additional Costs, such Buyer shall either agree
in writing to accept the obligation to pay Seller all such Additional Costs or
the Buyer may, in the exercise of its sole and absolute discretion, withdraw the
request for such addition or substitution. Seller shall not incur any Additional
Costs on behalf of the Buyer unless and until Seller has received Buyer's
written agreement to pay the Additional Costs and Seller and the Buyer have
agreed upon the purchase price for such similar Product type. Thereafter, Seller
shall use commercially reasonable efforts to produce such similar Product type
as requested, subject to such similar Product type achieving Production
Qualification under the procedures set forth in Section 4.2. Once a Buyer has
agreed to pay Additional Costs, such Buyer shall pay to Seller all such
Additional Costs within thirty (30) days of Seller's invoice therefor. If Seller
does not receive full payment of Additional Costs within thirty-five (35) days
after the date of invoice, the invoice price shall bear interest from the date
of invoice until paid in full at the annual rate equal to 5% above the prime or
reference rate for commercial borrowing announced by Bank of America N.T. &
S.A., as such rate changes from time-to-time; provided, however, that in no
event shall such interest rate exceed the highest rate permissible under
applicable law.

         5.5 VENDOR INFORMATION. Upon a Buyer's written request, Seller shall
provide the Buyer with (a) Process control information, including but not
limited to: Process and electrical test yield results, current Process
specifications, calibration schedules and logs for equipment, environmental
monitor information for air, gasses and DI water, documentation or operator
qualification and training, documentation of traceability through Seller's
operation, Process verification information, and Seller's trouble reports with
respect to Process control information; and (b) a status of work-in-process.

         5.6 PROCESS RECORDS. Seller shall maintain, for a period of five (5)
years from the date that any Qualified Process was performed to produce Proven
Products, accurate records describing in detail such Qualified Process on a
by-die-lot basis. Seller shall give each Buyer the right, at any time during
Seller's normal business hours and upon reasonable notice, to inspect and make
copies of any of Seller's Qualified Process records.

         5.7 TRADEMARKS. With respect to trademarks, the Parties agree as
follows:


                                       15
                                                       FUTURE PURCHASE AGREEMENT
   119
                  5.7.1 Except as authorized in Subsection 5.7.2, Seller shall
not, at any time, in any place, or in any manner, utilize the trademarks of the
Buyers, nor any name or logo confusingly similar thereto, in connection with
Seller's business activities, or in the manufacture, use, sale or other
disposition of Products, or in any other way whatsoever.

                  5.7.2 To the extent and only to the extent required by any
Buyer, such Buyer may give Seller written authorization to symbolize or
otherwise mark Proven Products with the authorizing Buyer's trademarks or other
proprietary logos.

                 5.7.3 No Buyer shall, at any time, in any place, or in any
manner utilize the trademarks of Seller or any of the other Buyers, or any name
or logo confusingly similar thereto, in connection with the Buyer's business
activities, or the use, sale or other disposition of Products, or in any other
way whatsoever.

         5.8 MASK SET PROTECTION. Seller shall protect all mask sets, whether
transferred from a Buyer (or its customer) or obtained by Seller from a mask
vendor of a Buyer (or its customer), as trade secrets of each Buyer in
accordance with the confidentiality provisions of (a) Article 15 hereof, and (b)
any license or confidentiality agreement entered into between Seller and a Buyer
or any Affiliate thereof. Any masks generated by Seller from a Buyer's database
tapes shall be the property of the Buyer. When any mask set is no longer usable
by Seller for the purposes hereof, or upon the termination or expiration hereof,
Seller shall either immediately return such mask set to the appropriate party,
or upon such party's written instructions, destroy such mask set and provide
such party with written certification of such destruction. The Buyers understand
that mask sets, if not used for a specified period of time, will be handled in
accordance with Seller's idle mask policy then in effect. Seller agrees, upon
written request of a Buyer, to disclose its idle mask policy to such Buyer. It
shall be a Buyer's responsibility to advise its customers of Seller's idle mask
policy.

         5.9 RIGHTS TO INSPECT AND MONITOR PRODUCTION. Each Buyer shall have the
following rights to inspect and monitor production at the Foundry:

                  5.9.1 Each Buyer (or, in the case of TSMC, any of its
customers) shall have the right to maintain at the Foundry, at its sole
discretion and expense, one or more resident representatives for the purpose of
ensuring compliance with the Quality and Reliability Specifications applicable
to Proven Products and otherwise aiding the Buyer in exercising its rights under
this Section 5.9. Seller shall provide suitable office space for use by such
representative(s) and shall provide access to the Foundry as is required for
assuring said compliance. Such inspectors may conduct independent source
inspections, at the Buyer's (or such customer's) expense, prior to shipment.
Office space provided to such inspectors, telephone, telecopy, photocopy and any
other office services used by such inspectors shall be billed to the Buyer (or
to such customers) on a full-cost-recovery basis, as determined by Seller's
management.

                  5.9.2 Seller agrees to allow each Buyer (or, in the case of
TSMC, any of its customers) to perform, upon reasonable written notice to
Seller, quality or yield audits of the 


                                       16
                                                       FUTURE PURCHASE AGREEMENT
   120
Foundry. Any such audit shall be conducted (a) at the expense of the Buyer (or
such customer) and (b) in a manner designed to cause the least possible
disruption to production at the Foundry. Prior to commencing any such audit,
Buyer (or such customer) shall submit for Seller's prior approval an audit plan
specifying the scope of its audit, the personnel to be involved therein, and the
estimated time required to complete the audit. Seller shall not unreasonably
withhold its consent to such plan, provided that as conditions precedent to
Seller's consent to any such audits the Buyer or such customer, as the case may
be, and each individual involved in the audit shall execute and deliver a
confidentiality agreement in the form of Exhibit "J" attached hereto.

                  5.9.3 During completion of production lots, each Buyer (or any
of its customers) shall have the right to perform monitoring tests and may
recommend disposition/corrective action where variance from the Quality and
Reliability Specifications exists. Seller shall support this activity with
quality trend reports and such other documentation as shall be requested from
time to time by the Buyer (or such customer). In addition, if at any other time
the Buyer (or such customer) detects variances from Quality and Reliability
Specifications, the Buyer (or such customer) may recommend such corrective
actions to Seller.

                  5.9.4 Subject to a Buyer's customer signing a confidentiality
agreement with Seller substantially in the form of Exhibit "K," Seller shall
grant to such customer the right to inspect the Foundry, to conduct quality
audits of the Foundry, and to review Design Rules at the Foundry.

         5.10 OBTAIN GRANT OF NON-EXCLUSIVE MANUFACTURING RIGHTS. To the extent
that the proposed manufacture of any Products ordered by a Buyer hereunder
requires, in the reasonable judgment of Supplier, the grant of non-exclusive
Intellectual Property Rights (including, by way of illustration but without
limitation, a nonexclusive grant in mask work rights, copyrights, patents,
utility models or design rights and applications for any of the foregoing) to
avoid infringement resulting from manufacture or sale of such Products, the
Buyer agrees to obtain and grant to Seller non-exclusive rights in such
Intellectual Property Rights relating to ordered Products, whether by way of
non-exclusive license, sublicense, have-made rights or otherwise, for the sole
purpose of manufacturing such Products for sale to the Buyer. Any such grant of
non-exclusive Intellectual Property Rights shall not confer the right on Seller
to grant rights to others under any of the foregoing (unless expressly provided
for in the granting instrument). Notwithstanding the foregoing, a Buyer may
decline to obtain a license in such Intellectual Property Rights if the Buyer
executes and delivers to Seller a written indemnification agreement
substantially in the form of Exhibit "L" attached hereto, whereby the Buyer
agrees to indemnify, defend and hold Seller harmless from any Claims of
infringement or misappropriation asserted by holders of such Intellectual
Property Rights. Seller will not manufacture or deliver Proven Products, Test
Wafers or Risk Wafers unless and until the Buyer has (a) obtained and granted
the necessary non-exclusive Intellectual Property Rights to Seller; or (b)
executed and delivered to Seller such indemnity agreement. The provisions of
this Section 5.10 shall not apply to any Process covered by Supplier's
indemnification obligations under Section 11.1 below.

         5.11 UNIQUE PROCESSES, METHODS OR MATERIALS. If a Buyer desires that
Seller load a Process, method or materials at the Foundry that is unique to the
Buyer (i.e., one that (a) in the



                                       17
                                                       FUTURE PURCHASE AGREEMENT
   121
case of a Process, deviates from a Qualified Process that is then in use at the
Foundry, and (b) in the case of a method and materials, deviates from methods
and materials then in use or production at the Foundry), such Buyer shall give
Seller written notice thereof. If Seller agrees to load a unique Process, method
or materials at the Foundry, then within a reasonable amount of time after
Seller's receipt of the Buyer's notice, Seller shall notify the Buyer in writing
of any additional costs associated with such unique Process, method or
materials, including, without limitation, purchase part and work-in-process
inventory, supplies, tooling, and any equipment that is specific to such unique
Process, method or materials (collectively, "Unique Costs"). Within thirty (30)
days of its receipt of Seller's written notification of Unique Costs, such Buyer
shall either agree in writing to accept the obligation to pay Seller all such
Unique Costs or the Buyer may, in the exercise of its sole and absolute
discretion, withdraw the request for such unique Process, method or materials.
Seller shall not incur any Unique Costs on behalf of a Buyer unless and until
Seller has received Buyer's written agreement to pay such Unique Costs. Once a
Buyer has agreed to pay Unique Costs, such Buyer shall pay to Seller all such
Unique Costs within thirty (30) days of Seller's invoice therefor. If Seller
does not receive full payment of Unique Costs within thirty-five (35) days after
the date of invoice, the invoice price shall bear interest from the date of
invoice until paid in full at the annual rate equal to 5% above the prime or
reference rate for commercial borrowing announced by Bank of America N.T. &
S.A., as such rate changes from time-to-time; provided, however, that in no
event shall such interest rate exceed the highest rate permissible under
applicable law.

         5.12 ADJUSTMENT IN CAPACITY RIGHTS AND OBLIGATIONS; ADMISSION OF NEW
BUYERS.

                  5.12.1 ADJUSTMENT. Unless otherwise agreed in writing by the
Parties, any adjustment in the Buyers' Percentage Interests which results in a
change in their Adjusted Percentage Interests (as defined in Subsection 1.1.3)
shall not become effective for purposes of the Buyers' Basic Purchase Shares
until the thirteenth (13th) week after the date upon which the adjustment in
Percentage Interests occurs pursuant to the LLC Agreement, and unless agreed
otherwise by Seller and each Buyer under a Purchase Order, no such adjustment in
Percentage Interests, when so effective, shall operate to cancel, amend or
otherwise affect any Purchase Orders accepted by Seller prior to the date that
such adjustment in Percentage Interests is so effective.

                  5.12.2 NEW BUYERS. A Person (a) which is admitted to
membership in Seller (i) pursuant to Section 3.3 or 10.5 of the LLC Agreement or
(ii) following a permitted Transfer of a Membership Interest or part thereof by
a member of Seller and (b) which acquires pursuant to the LLC Agreement (or any
amendment thereof) rights and obligations to purchase Products from Seller shall
be become a Buyer upon executing and delivering to the Board of Directors such
instruments, including an agreement to be bound by the terms hereof, as are
reasonably satisfactory in form and substance to the Board of Directors.

         5.13 CERTAIN TERMS APPLICABLE TO TEST WAFERS. The provisions of
Section 6.2 through 6.5, inclusive, and Article 7 respecting Proven Products
shall be equally applicable to Test Wafers. There is no product warranty under
Article 9 for Test Wafers unless Seller and the 


                                       18
                                                       FUTURE PURCHASE AGREEMENT
   122
applicable Buyer agree to such warranty in writing prior to shipment. If Seller
and the applicable Buyer do enter into such a written product warranty, then
Test Wafers covered by such warranty shall be treated as Proven Products under
the provisions of Article 9. Additionally, Test Wafers covered by such written
product warranty shall be treated as Proven Products under Article 8. If Test
Wafers are not covered by a written product warranty, then Seller shall provide
the applicable Buyer with Seller's Wafer acceptance test parameters and outgoing
visual acceptance criteria (such parameters and criteria, collectively, the
"Wafer Acceptance Criteria"). If on delivery of Test Wafers to such Buyer, the
Test Wafers fail an incoming test under the Wafer Acceptance Criteria, such Test
Wafers shall be deemed to be defective. Any such defective Test Wafers may be
returned within 120 days of the Buyer's receipt thereof to Seller, F.O.B. the
Foundry, and if such defective Test Wafers are indeed defective and not caused
by Abuse and Misuse (as defined below), then Seller shall, at its option, either
repair, replace or credit the Buyer for such defective Test Wafers; and
furthermore, Seller shall return any such Test Wafers repaired or replaced to
the applicable Buyer, transportation prepaid, and shall reimburse the Buyer for
the transportation charges paid by it for returning such defective Test Wafers
to Seller. Any dispute regarding whether Test Wafers fail an incoming test under
the applicable Wafer Acceptance Criteria or whether Test Wafers have been
subjected to Abuse and Misuse shall be resolved in accordance with Article 17.

         5.14 CERTAIN TERMS APPLICABLE TO RISK WAFERS RUN ON A QUALIFIED
PROCESS. For any Risk Wafers run on a Qualified Process ("RWRQPs"), Seller shall
provide the applicable Buyer with Seller's Wafer Acceptance Criteria (as that
term is defined in Section 5.13). If on delivery of RWRQPs to such Buyer, the
RWRQPs fail an incoming test under the Wafer Acceptance Criteria, such RWRQPs
shall be deemed to be defective. Any such defective RWRQPs may be returned
within one hundred twenty (120) days of the Buyer's receipt thereof to Seller,
F.O.B. the Foundry, and if such defective RWRQPs are indeed defective and not
caused by Abuse and Misuse (as defined below), then Seller shall, at its option,
either repair, replace or credit the Buyer for such defective RWRQPs; and
furthermore, Seller shall return any such RWRQPs repaired or replaced to the
applicable Buyer, transportation prepaid, and shall reimburse the Buyer for the
transportation charges paid by the Buyer for returning such defective RWRQPs to
Seller. Any dispute regarding whether RWRQPs fail an incoming test under the
applicable Wafer Acceptance Criteria or whether RWRQPs have been subjected to
Abuse and Misuse shall be resolved in accordance with Article 17.

         5.15 SALE OF RISK WAFERS. Seller shall sell Risk Wafers if so requested
by a Buyer, subject to the negotiation of a mutually acceptable risk start
agreement.

                                    PURCHASES

         6.1  PURCHASE ORDERS.

                  6.1.1 Subject to the provisions of Section 3.3 and 4.1, each
Buyer shall place Purchase Orders for such quantities of Products according to
the current Production Plan. The Purchase Orders shall (a) be open purchase
orders for fixed quantities of Products; (b) constantly cover a twelve (12) week
period (unless Seller's standard production lead time for a particular Product
exceeds twelve (12) weeks, in which case Purchase Orders for such Product shall
constantly cover a period that is two weeks longer than Seller's standard
production lead time for the Product in question); (c) be placed with Seller no
later than sixty (60) days prior to the shipment date specified in such Purchase
Order; (d) constitute firm purchase obligations on the part of each Buyer, and
(e) be final, subject only to acceptance by Seller, which acceptance shall not
be unreasonably withheld or delayed. Seller may accept a Buyer's Purchase
Order(s) either by written acknowledgement of the Purchase Order(s) placed or by
shipment of the Products ordered. On or before seven (7) Business Days prior to
the date that Seller commences production of Proven Products ordered by a Buyer,
such Buyer may substitute other Proven Products that have a currently-assigned
product model number for those actually ordered without incurring any
administrative cost therefor.

                  6.1.2 Purchase orders otherwise to be placed by TSMC in the
manner specified in Subsection 6.1.1 may be placed by any customer of TSMC
directly to Supplier. Supplier shall accept any such customer's purchase order
that otherwise conforms to the requirements hereof.

                  6.1.3 Seller shall notify a Buyer of any anticipated problems
in filling a Purchase Order within twenty-five (25) days following its receipt.
To the extent that the terms of any Purchase Order or any Seller corresponding
quotation, order acknowledgment, or invoice conflict herewith, this Agreement
shall be controlling unless Seller and the Buyer placing the Purchase Order
expressly agree to the contrary. To the extent that the terms of any Purchase
Order conflict with the terms of Seller's corresponding quotation, order
acknowledgment, or invoice (the so-called "battle of the forms"), Seller's
quotation, order acknowledgement or invoice shall be controlling unless Seller
and the Buyer placing the Purchase Order expressly agree to the contrary.

         6.2 PRICE. Seller shall sell Proven Products, Test Wafers and Risk
Wafers to Buyers in accordance with the Pricing Schedule in effect at the time
of shipment, subject to the following:

                  6.2.1 The prices quoted in each Pricing Schedule shall be firm
and valid until the Pricing Schedule is amended in accordance with Subsections
6.2.3(b) or 6.2.3(c).

                  6.2.2 The Prices quoted in the Pricing Schedule are in U.S.
currency and net of any and all taxes and duties, including but not limited to
customs duties, sales tax, value added tax, use tax, and excise tax. Each Buyer
shall be responsible for all applicable taxes (including 


                                       20
                                                       FUTURE PURCHASE AGREEMENT
   124
one or more of the above taxes), in addition to the prices quoted in the Pricing
Schedule that relate to a Buyer's order.

                  6.2.3 The initial pricing, quarterly pricing and annual
pricing shall be set as follows:

                           (a) The initial pricing under this Agreement shall be
         the prices quoted on the Pricing Schedule attached to the Original
         Purchase Agreement on the date that the Original Purchase Agreement
         expired or terminated, which Pricing Schedule shall be deemed to be
         attached hereto as Exhibit "A" as the initial Pricing Schedule
         hereunder.

                           (b) On a Quarterly basis, Seller shall do the
         following: For each Process loaded or to be loaded at the Foundry,
         Seller shall exert its best efforts to obtain from TSMC Taiwan an
         average price for such Process in use at all of TSMC Taiwan's and its
         Affiliates' Taiwanese semiconductor-wafer manufacturing plants in the
         previous calendar quarter, and such average price shall be the "Market
         Price" for each such Process to be used to manufacture Products at the
         Foundry. Within ten (10) Business Days after the beginning of each
         Quarter, Seller shall provide each Buyer in writing with its
         determination of the Market Price (based on the prior calendar quarter)
         for each Process used to manufacture Products included in the Buyer's
         then-current rolling six (6) Month forecasts ("Seller's Quarterly
         Pricing Report"). If the Market Price (as set forth in Seller's
         Quarterly Pricing Report) for the Process to be used to manufacture a
         particular Product deviates, up or down, by more than three percent
         (3%) from the price of such Process used to calculate pricing for
         Products shown on the Pricing Schedule, the price for the Process and
         for each Product in question shall be revised accordingly, and such
         revised price shall be reduced to writing and signed by the Parties,
         and shall be deemed to be attached hereto as an addendum to Exhibit
         "A", which shall be the new Pricing Schedule in respect to that
         Product. If any one or more of the Buyers objects to any Market Price
         set by Seller in Seller's Quarterly Pricing Report, (the "Objecting
         Buyers"), then the Objecting Buyers may request that Seller obtain
         permission from TSMC Taiwan to conduct an audit of TSMC Taiwan's and
         its Affiliates' books and records containing information necessary to
         confirm Seller's calculation of such Market Price for each Process and
         Product in question. If such permission is granted by TSMC Taiwan, the
         audit shall be conducted by Price Waterhouse & Company or by another
         public accounting firm nationally recognized in the United States of
         America selected by the Objecting Buyers and reasonably acceptable to
         TSMC Taiwan. Seller shall exert its best efforts to cause TSMC Taiwan
         to cooperate in the audit, cause its Affiliates to do the same, and, if
         requested by the auditors, shall request any subcontractor of TSMC
         Taiwan or of a TSMC Taiwan Affiliate to likewise cooperate. The
         Objecting Buyers shall pay the cost of the audit unless the audit
         reveals a discrepancy of more than three percent (3%) from the Market
         Price in the average price of any Process and the related Product in
         question, which three percent (3%) discrepancy must result in a higher
         Market Price quoted by Seller than calculated by the auditors based on
         their audit of TSMC Taiwan's and its Affiliates' relevant books and

         Taiwan's standard procedures for translating pricing of Processes into
         pricing for Products manufactured by such Processes. In the event of
         such three percent (3%) discrepancy, Seller shall pay the cost of the
         audit, the price for the Process in question as established by the
         audit shall be the new price for such Process, and the auditors shall
         calculate the pricing for Products to be manufactured using such
         Process based upon TSMC Taiwan's standard procedures for translating
         pricing of Processes into pricing for Products manufactured by such
         Processes. The new prices as established by the auditors shall be
         reduced to writing and signed by the Parties and shall be deemed to be
         attached hereto as an addendum to Exhibit "A", which shall be the new
         Pricing Schedule in respect to the Products in question. In no event
         shall there be more than two (2) audits of Seller's Quarterly Pricing
         Report figures in any calendar year.

                           (c) The Parties shall annually renegotiate the prices
         for all Processes used to manufacture Products for each succeeding
         calendar year, which annual price negotiation shall commence on or
         about August 1 of the then-current year. In advance of the annual price
         negotiation, Seller shall provide each Buyer in writing with its
         determination of the Market Price for each Qualified Process used to
         manufacture Products included in the Buyer's then-current rolling six
         (6) Month forecast. Once the Parties have agreed upon the renegotiated
         prices for a succeeding year, such renegotiated prices shall be reduced
         to writing and signed by the Parties, and shall be deemed to be
         attached hereto as Exhibit "A" as the Pricing Schedule in effect at the
         beginning of such year such year. If no agreement can be reached with
         respect to renegotiating prices by September 30 of the then-current
         year, the Parties shall submit pricing to binding arbitration under
         Section 17.3 through 17.7, inclusive; subject to the further provisions
         of Subsection 6.2.3(d).

                           (d) With respect to binding arbitration conducted
         pursuant to Subsection 6.2.3(a) and 6.2.3(c) above, in advance of the
         hearing each Party shall submit to the arbitrator and exchange with the
         other Parties their last best offers with respect to pricing. In
         addition to the matters set forth in Section 17.3 through 17.7, the
         arbitrator shall base his award on his determination of Market Price
         (as defined in Subsection 6.2.3(b) above) for each Process to be used
         for manufacture of Products hereunder, and on his determination of
         price for each Product manufactured by means of such Process, based on
         TSMC Taiwan's standard procedures for translating pricing of Processes
         into pricing for Products manufactured by such Processes. The highest
         price submitted by any Party for a specific Product shall be the
         maximum price that the arbitrator shall be empowered to award for that
         Product, and the lowest price for a specific Product submitted by any
         Party shall be the minimum price that the arbitrator shall be empowered
         to award for that Product. For each Product, it is understood among the
         Parties that if the arbitrator awards an amount between (and including)
         the minimum and maximum prices submitted by the Parties for such
         Product, then the exact award amount shall be the price set for that
         Product in the applicable year. The prices as so set by the arbitrator
         thereafter shall be subject to quarterly adjustment as described in
         Subsection 6.2.3(b) above.

                           (e) All pricing for Products calculated or published
         pursuant to this Section 6.2 shall be expressed as a price per Wafer.

         6.3 INVOICE. Upon shipment of any Proven Products, Test Wafers or Risk
Wafers, Seller shall invoice the sale. Applicable taxes, freight, and insurance
paid by Seller shall be separately stated on the invoice.

         6.4 PAYMENT. Unless otherwise agreed upon by Seller and the ordering
Buyer, payment terms shall be net due thirty (30) days after the date of
Seller's invoice (the "Invoice Payment Date"). For any invoice that is due and
owing under this Section 6.4 which is not paid within thirty-five (35) days
after the date of invoice, the invoice amount shall bear interest from the
Invoice Payment Date until paid in full at the annual rate equal to 5% above the
prime or reference rate for commercial borrowing announced by Bank of America
N.T. & S.A., as such rate changes from time to time; provided, however, that in
no event shall such interest rate exceed the highest rate permissible under
applicable law. Any payment made hereunder shall be in U.S. dollars.

         6.5 NO LIMITATION ON BUYER'S PRICING. The prices charged by Seller to a
Buyer hereunder shall not limit in any way the prices that the Buyer may charge
its customers.

combination with all the other partial shipments made for the same Purchase
Orders.

         7.5 FAILURE TO MEET DELIVERY DATES. Delivery made within +/-10 days of
the delivery dates specified in Purchase Orders accepted by Seller are deemed

for any material failure by Seller, which failure is the direct result of any
act or omission of the Buyer, its employees or agents (or any act or omission of
the Buyer's customer or the customer's employees or agents). Seller shall not be
liable for any penalty or any indirect, special, incidental or consequential
damages imposed upon or incurred by a Buyer as a result of failure of Seller to
timely deliver Proven Products or Risk Wafers.

         7.6 FORCE MAJEURE. Whenever any actual or potential event of Force
Majeure that reasonably can be anticipated (e.g., a labor dispute) delays or
threatens to delay the timely performance of any delivery under a Purchase
Order, Seller shall promptly give notice thereof to the impacted Buyer. Whenever
any actual or potential event of Force Majeure reasonably can be anticipated to
delay or threaten to delay a Buyer's ability to accept delivery under a Purchase
Order, such Buyer shall promptly give notice thereof to Seller.

thereof. If no notification indicating rejection is received by Seller within
the above time period, then such Proven Products shall be deemed accepted.
Except as otherwise provided in Section 5.14, Risk Wafers must be accepted.

                                PRODUCT WARRANTY

         9.1 SELLER'S WARRANTY. Seller warrants that the Proven Products
delivered hereunder shall meet the Quality and Reliability Specifications and
shall be free from defects in materials and workmanship under normal use for a
period of one (1) year from the date of shipment. If, during the one year
period, (a) Seller is notified promptly in writing upon discovery of any defect
in the Proven Products, including a detailed description of the alleged defect,
(b) such Proven Products are returned to Seller, F.O.B. the Foundry, and (c)
such Proven Products are indeed defective and not caused by accident, abuse,
misuse, neglect, improper installation or packaging, repair or alteration by
someone other than Seller, or improper testing or use contrary to any
instructions given by Seller (collectively, "Abuse or Misuse"), then Seller
shall, at its option, either repair, replace, or credit a Buyer for such
defective Proven Products. Seller shall return any Proven Products repaired or
replaced under this warranty to a Buyer transportation prepaid, and shall
reimburse a Buyer for the transportation charges paid by the Buyer for returning
such defective Proven Products to Seller. The performance of this warranty shall
not act to extend the one-year warranty period for any Proven Products repaired
or replaced beyond that period applicable to such Proven Products as originally
delivered. There is no warranty for Risk Wafers. Unless otherwise expressly
agreed to the contrary by Seller and a Buyer in writing prior to shipment, there
is no warranty for Test Wafers.

         9.2 LIMITED WARRANTY. THE WARRANTIES HEREIN (A) ARE EXCLUSIVE AND

a Buyer pursuant to Section 9.1, such Buyer shall first afford Seller the
opportunity, upon Seller's request, to inspect the allegedly defective Proven
Products at such Buyer's facilities. If Seller thereby determines that the
allegedly defective Proven Products are defective or non-conforming with the
applicable Quality and Reliability Specifications, or that such alleged defects
are caused by defects in material or workmanship of Seller, as the case may be,
then the Buyer shall be entitled to repair, replacement

Proven Products are not defective or conform with the applicable Quality and
Reliability Specifications, the disagreement with respect to defectiveness or
non-conformity shall be resolved pursuant to Article 17. Inspection and

PROPRIETARY INFORMATION IN VIOLATION OF ARTICLE 15, A PARTY SHALL BE LIABLE FOR
ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGE (INCLUDING WITHOUT
LIMITATION, LOSS OF PROFITS OR LOSS OF USE) SUFFERED BY ANY OTHER PARTY ARISING
FROM OR RELATING TO A PARTY'S NON-PERFORMANCE, BREACH OF OR DEFAULT UNDER SAID

relying Party was entitled to rely thereon, or where a Party fraudulently
concealed the existence of a cause of action, the claims shall be commenced
within two (2) years of the date that the aggrieved Party discovered the
material facts giving rise to the cause of action.

                                   INDEMNITIES

         11.1 INTELLECTUAL PROPERTY INDEMNITY. Subject to the limitations set
forth in Article 10 and in Subsection 11.1.1 below, Seller shall, at its expense
and at a Buyer's request, defend or settle any Claim brought against the Buyer
to the extent that it is based solely on an allegation that a Process that is
normally specified and used by Seller in the manufacture of a Proven Product or
RWRQPs pursuant to this Agreement directly infringes any Intellectual Property
Rights of a third party, and Seller shall pay all costs and damages finally
awarded against such Buyer for such infringement, provided that such Buyer
complies with the provisions of Section 11.4 below.

                  11.1.1 Seller shall have no liability under this Agreement for
any Claim (a) where infringement is attributable, in whole or in part, to (i)
Seller's compliance with or implementation of any Buyer's instructions,
specifications, designs, mask works, utility models, or requirements, (ii) a
Process (insofar as a Process or any part thereof has been specified by a Buyer
to Seller and the deviation of the Buyer's specifications from Seller's normal
specifications causes direct or contributory infringement), or (iii) other
information or materials provided by a Buyer to Seller for the performance of
this Agreement, or (b) relating to Risk Wafers that are not run on a Qualified
Process, and the applicable Buyer shall indemnify, defend, protect and hold
Seller harmless from and against any and all such Claims, provided that Seller
complies with the provisions of Section 11.4 below.

                  11.1.2 If the court or a settlement enjoins the use of a
Process by Seller, or if, in Seller's opinion, a Process is likely to become the
subject of a claim of infringement, then the Party providing the Process shall
have the option to modify such Process so that it becomes non-infringing,
substitute a substantially equivalent non-infringing Process, or obtain the
right to continue using such Process. If the curative actions described in the
preceding sentence cannot be accomplished within a reasonable period of time,
Seller shall have the right to decline to manufacture or to continue to
manufacture Proven Products or Risk Wafers using such Process.

                  11.1.3 The foregoing states the entire liability and exclusive
remedies of Seller and each Buyer for infringement of a third party's
Intellectual Property Rights by Proven Products, Test Wafers, Risk Wafers or
Processes used to manufacture any Products furnished hereunder.

protect and hold Seller harmless against any and all Claims arising out of
injury or death of any of such Buyer's

personnel assigned to work at the Foundry, or while performing tasks at the
Foundry pursuant hereto or any other agreement or instrument to which a Buyer
and Seller are parties in connection herewith, notwithstanding that such
personnel are in Seller's care, custody or control while at the Foundry,
provided that this indemnity shall not apply in any instance in which such
Claims are based upon the gross negligence or willful misconduct of Seller or
its employees or agents.

         11.3  PRODUCT LIABILITY.

                  11.3.1  Except as otherwise expressly provided herein:

                           (a) Seller shall have no liability under this
         Agreement or otherwise for any product liability Claim with respect to
         any of the Proven Products, Risk Wafers or Test Wafers, whether such
         product liability Claim is based on alleged defects in the design,
         manufacture, or packaging of Proven Products, Risk Wafers or Test
         Wafers or on any other adverse conditions.

                           (b) Each Buyer, on behalf of itself and any of its
         Affiliates that purchase or resell Proven Products, Risk Wafers or Test
         Wafers, hereby waives, releases and discharges Seller from and against
         any and all Claims arising from or relating to product liability,
         including, without limitation, Claims based on alleged defects in the
         design, manufacture or packing of Proven Products, Risk Wafers or Test
         Wafers or on any other adverse conditions. The foregoing waiver,
         release and discharge is intended to extend to any and all product
         liability Claims of any kind or character, whether fixed or contingent,
         known or unknown.

                  11.3.2 Seller's sole and exclusive liability and obligation
with respect to any defective Proven Product and any Test Wafers covered by a
written product warranty shall be as set forth in Section 9.1. Seller's sole and
exclusive liability and obligation with respect to defective Test Wafers not
covered by a written product warranty shall be as set forth in Section 5.13.
Seller's sole and exclusive liability and obligation with respect to defective
RWRQPs shall be as set forth in Section 5.14.

                  11.3.3 Each Buyer shall indemnify, defend, protect and hold
Seller, harmless against any and all product liability Claims brought by third
parties, including, without limitation, any of a Buyer's customers or any
ultimate end users of any product, system or subsystem into which a Proven
Product, Test Wafer or Risk Wafer (or any part thereof) has been incorporated.
The foregoing shall not apply, however, to the extent any such Claims result
from the negligence or willful misconduct of Seller.

         11.4 GENERAL INDEMNITY PROVISIONS. Each Party's indemnification
obligations hereunder shall be subject to the following provisions:

                  11.4.1 Indemnitor's indemnification obligations also shall
extend to any one or more of indemnitee's officers, directors, managers,
shareholders, members, employees, and agents.

                  11.4.2 Each Party's indemnification obligations hereunder
shall survive the early termination or expiration of the Term for the remainder
of the statutory limitations period governing actions on a written agreement.

                  11.4.3 Each Party's obligation to indemnify any other Party
hereunder shall be conditioned upon:

                           (a) Indemnitee's giving indemnitor prompt notice in
         writing of any Claims giving rise to the obligation to indemnify and of
         which indemnitee is aware;

                           (b) Indemnitee's permitting indemnitor, through
         counsel of indemnitor's choice and reasonably acceptable to indemnitee,
         to defend against, contest or settle the same; and

                           (c) Indemnitee's reasonably cooperating with
         indemnitor and reasonably providing indemnitor with information and
         assistance to enable indemnitor to defend, contest or settle same.

                  11.4.4 Unless expressly provided to the contrary, the
indemnification provisions herein shall be interpreted and construed as
indemnifying indemnitee against indemnitee's negligence, whether active or
passive.

                                   ARTICLE 12
                                  FORCE MAJEURE

         12.1 FORCE MAJEURE. Subject to the limitations set forth in Section 
12.4, should a Party be prevented from performing its obligations hereunder due
to a Force Majeure event, that Party shall not be liable to the other Parties
for any delay or failure of performance caused by such event; nor shall the
Party subject to such event be deemed to have committed an Event of Default
hereunder. Notwithstanding the foregoing, a Force Majeure event shall not excuse
a Party's obligation to pay money. However, a monetary obligation shall be
suspended until cessation of such Force Majeure event if, and only if, the Force
Majeure event actually and directly renders physically impossible a Party's
payment of money due hereunder.

         12.2 NOTIFICATION. The Party prevented or delayed by an event of Force
Majeure in the performance of any obligation hereunder shall promptly notify the
affected Party or Parties of the occurrence of any Force Majeure event by cable,
telex or telecopier.

         12.3 RESPONSE TO FORCE MAJEURE. Should the delay caused by a Force
Majeure event continue for more than ninety (90) days, the Parties shall settle
the problem of further performance of this Agreement through good faith
negotiations as soon as possible with the objective of restructuring the
relationship among themselves to minimize the effects of such event. If the
Parties cannot agree on a mutually acceptable solution within one hundred twenty
(120)

   133
days of a Party's request for such negotiations, any Party that is not
subject to the Force Majeure event may terminate this Agreement by notice to the
other Parties. If the Party giving notice of termination is a Buyer, the
termination shall be effective only as to such Buyer, and this Agreement shall
continue in full force and effect among Seller and the non- terminating Buyers.
Notwithstanding the foregoing, no Buyer shall be permitted to terminate this
Agreement due to the Buyer's inability to pay for its Minimum Purchase Share or
to otherwise meet its financial obligations due to a continuing Force Majeure
event.

         12.4 LIMITATIONS ON APPLICABILITY OF FORCE MAJEURE. This Article shall
be void and inapplicable to any Party (a) if it fails to use reasonable
diligence to remedy any Force Majeure event that prevents or delays that Party's
performance hereunder by continuously pursuing such actions as that Party
reasonably can take under the circumstances; and (b) in the event of a strike,
lockout or other labor disruption, if the Party is found by the National Labor
Relations Board or other governmental agency having jurisdiction to have caused
such strike, lockout or labor disruption or if such Party refuses to enter into
bargaining with respect to such strike, lockout or labor disruption.

                            GOVERNMENTAL INTERVENTION

         13.1 GOVERNMENTAL INTERVENTION. Should any government or agency thereof
at any time during the Term hereof take any action which is material and adverse
to a Party or make recommendations to the Parties or any of them requiring
directly or indirectly, formally or informally, alteration or modification of
any term or condition hereof, or of the performance of the Parties hereunder,
including refusal to grant any necessary government approval, in a manner which
is material and adverse to one Party, then, if said one Party makes written
request (the "Requesting Party") to the other Parties within sixty (60) days
from said action or recommendation of the government or governmental agency, the
Parties shall enter into good faith negotiations with the objective of
restructuring the relationship among the Parties to minimize the adverse effect
of said alteration or modification. If the Parties cannot reach a reasonably
acceptable modification hereto within six (6) months from the date of dispatch
of said written request by the Requesting Party, or within such longer period of
time as mutually agreed upon, the Requesting Party shall have the right to
terminate this Agreement forthwith by giving notice to that effect to the other
Parties; provided, however, that if the Requesting Party giving notice of
termination is a Buyer, the termination shall be effective only as to such Buyer
and this Agreement shall continue in full force and effect among Seller and the
non- terminating Buyers. It is expressly understood and agreed by the Parties
that in the event of termination under this Article, no Party shall incur any
liability to the others for any alleged default or breach in the performance
hereof, arising from the exercise of the right herein provided to terminate this
Agreement. Termination under this Article 13 shall not be deemed to be a
termination for default.

                             DEFAULT AND TERMINATION

         14.1 EVENTS OF DEFAULT. The occurrence or happening, at any time and
from time to time, of any one or more of the following shall be a breach or
default under this Agreement (an "EVENT OF DEFAULT"):

                  14.1.1 If any Party fails (a) to make any payment required to
be made pursuant to this Agreement when due, and such Party does not cure such
failure following thirty (30) days written notice thereof, or (b) to perform any
material obligation under this Agreement, and such Party does not cure such
failure following sixty (60) days written notice thereof.

                  14.1.2 If any Party breaches its obligations of non-disclosure
and confidentiality set forth in Subsection 15.1.1.

                  14.1.3 If any representation, warranty or statement made by
any Party under or pursuant to this Agreement, or under any affidavit,
certificate or other instrument executed in connection with this Agreement,
shall be false or misleading in any material respect as of the Effective Date or
shall become so at any time prior to the expiration of the Term, and such Party
does not cure (to the extent cure is possible) the same following thirty (30)
days written notice thereof.

                  14.1.4 If any Party files a certificate of dissolution or
otherwise dissolves, terminates or liquidates, or is merged with or is
consolidated into any other corporation, limited liability company, partnership,
or other entity other than an Affiliate of such Party, without the other
Parties' written consent (which consent shall not be unreasonably withheld);
provided that the following shall not be an Event of Default: (a) any
dissolution, liquidation, merger or consolidation that is permitted in
accordance with Section 18.14; and (b) any merger or consolidation not entered
into for the purpose of and not having the effect of changing or influencing the
control of the Party.

                  14.1.5 If any Party shall (a) be adjudicated as bankrupt or
insolvent; (b) make a general assignment for the benefit of its creditors; (c)
file a petition, answer or consent seeking, or have entered against it (or fail
reasonably to contest the material allegations of any petition for) an order for
relief (or any similar remedy) under any provision of Title 11 of the United
States Code or any other federal or state law relating to insolvency,
bankruptcy, rehabilitation, liquidation or reorganization, or consent to the
institution of any proceedings thereunder; (d) convene a general meeting of its
creditors, or any class thereof, for the purpose of effecting a general
moratorium upon or general extension or composition of its debts; (e) fail to
pay its debts as they mature; (f) admit in writing that it is generally not able
to pay its debts as they mature; or (g) apply for or consent to the appointment
of a receiver, trustee, custodian, liquidator or other similar official of all
or a substantial portion of its assets.

   135
                 14.1.6 If (a) a petition is filed or any case or proceeding
described in Section 14.1.5 above is commenced against any Party, or against the
assets thereof, unless such petition and the case or proceeding initiated
thereby is dismissed within sixty (60) days from the date of the filing; (b) an
answer is filed by any Party admitting the allegations of any such petition; (c)
a court of competent jurisdiction enters an order, judgment or decree
appointing, without the consent of any Party, a custodian, trustee, agent or
receiver of it, or for all or a substantial part of its property, or authorizing
the taking possession by a custodian, trustee, agent or receiver of it, or of
all or a substantial part of its property unless such appointment is vacated or
dismissed or such possession is terminated within sixty (60) days from the date
of such appointment or commencement of such possession, but not later than 5
days before the proposed sale of any assets of such Party by such custodian,
trustee, agent or receiver.

                  14.1.7 If a Buyer is terminated as a member of Seller pursuant
to Section 3.3.1, 3.3.2.2, or 10.2 of the LLC Agreement.

         14.2  REMEDIES FOR DEFAULT.

                  14.2.1 If the Party committing an Event of Default under
either Subsection 14.1.1, 14.1.3 or 14.1.4 above does not cure such Event of
Default within the applicable cure periods, then any non-breaching Party may,
subject to the procedures set forth in Article 17, seek:

                           (a) specific performance of the breaching Party's
obligations under this Agreement;

                           (b) damages suffered by said non-breaching Party as a
result of such Event of Default, limited, however, by the provisions of Article
10.

Except as otherwise expressly provided to the contrary herein, the non-breaching
Party shall not have a right to terminate the Agreement. If Seller is the
non-breaching Party and the Event of Default involves the non-payment of money
due to Seller from a Buyer, then Seller shall be entitled (in addition to any
other rights and remedies it may have hereunder, at law or in equity) to suspend
performance of all sales and services to that Buyer hereunder until all
delinquent amounts are paid in full. If the Event of Default is a breach by
Seller of its delivery obligations under Section 7.1, as qualified by Section 
7.5, for any reason other than Force Majeure, then the affected Buyer may, in
lieu of the remedies of specific performance, elect to cancel the Purchase Order
to the extent of any undelivered Proven Products, Test Wafers or Risk Wafers;
provided, however, that such Buyer shall remain obligated to pay for any partial
deliveries under such Purchase Order.

                  14.2.2 Each of the Parties acknowledges that a breach or
default by it of its covenants regarding non-disclosure and confidentiality
contained in Subsection 15.1.1 will result in irreparable injury to the Party
making disclosure of its Proprietary Information, and consequently the
disclosing Party shall be entitled to temporary, preliminary and permanent
injunctive relief, or to a protective order for any threatened or actual
violation of the provisions of


                                       32

   136
Subsection 15.1.1. Each Party agrees and consents to the entry of an injunction
or protective order by any court of competent jurisdiction upon a showing by the
disclosing Party of a reasonable belief that its Proprietary Information is
being used or disclosed contrary to the terms of Subsection 15.1.1. The
foregoing provisions are in addition to, and not in limitation of, the remedies
of specific performance, damages, and any other remedies at law, in equity or
otherwise, that the Parties may have upon breach of Subsection 14.1.2; provided,
however, that the non-breaching Party shall not have the right to terminate this
Agreement. The Parties stipulate that the provisions of Article 17 shall not
apply to any temporary restraining order, injunctive relief, protective order or
other provisional remedy sought to prohibit a breach or threatened breach of the
provisions of Subsection 15.1.1.

                  14.2.3 In the event of an Event of Default under Subsection
14.1.5 or 14.1.6, the non-breaching Party or Parties shall have the right, at
its (their) option, to terminate this Agreement by giving ten (10) days prior
written notice of termination. If Seller and one or more of the Buyers are
non-breaching Parties, they, or any one or more of them may terminate this
Agreement by giving such written notice to the breaching Buyer or Buyers, in
which event this Agreement shall continue in full force and effect between
Seller and each of the non-breaching Buyers.

                  14.2.4 If a Buyer's Percentage Interest is reduced to zero in
accordance with the LLC Agreement, this Agreement shall terminate with respect
to the Buyer, subject to Section 5.12.1 (including the effective date provided
therein for the corresponding reduction in the Buyer's Basic Purchase Share and
the effect, if any, on Purchase Orders prior to the adjustment date). So long as
any Buyer has a positive Percentage Interest, this Agreement shall continue in
full force and effect between Seller and any such Buyer.

         14.3 EFFECTIVE DATE OF TERMINATION. Termination of this Agreement
pursuant to any notice of termination given under any provision of this
Agreement shall be effective ten (10) days following the date such termination
notice is deemed to be given pursuant to Section 18.3 below.

         14.4 RIGHTS AND REMEDIES FOLLOWING TERMINATION. The termination of this
Agreement shall be without prejudice to (a) the right of Seller to receive upon
its request all payments accrued and unpaid hereunder; (b) the rights and
remedies of any Party with respect to any previous breach of any other
representations, warranties, covenants, terms, conditions or provisions of this
Agreement (provided that the limitation on liability set forth in Article 10
shall apply to such rights and remedies); (c) any rights to indemnification set
forth herein; and (d) any other provisions hereof which expressly or necessarily
call for performance after the termination of this Agreement.

         14.5 REMEDIES CUMULATIVE, CONCURRENT AND NON-EXCLUSIVE. The Parties
shall have all rights, remedies and recourse granted in this Agreement, in any
other agreements entered into between the Parties, and available at law or in
equity, and except as otherwise provided in this Agreement the same (a) shall be
cumulative and concurrent; (b) may be pursued separately, successively or
concurrently; (c) may be exercised as often as occasions therefor shall arise,
it

   137
being agreed that the exercise or failure to exercise any right, remedy or
recourse shall in no event be construed as a waiver or release thereof; and (d)
are intended to be, and shall be, non-exclusive.

                            PROPRIETARY INFORMATION

         15.1  PROPRIETARY INFORMATION.

                  15.1.1 Each Party agrees to maintain the other Parties'
Proprietary Information in strict confidence, not to make use thereof other than
for the performance of this Agreement, to release it only to employees who have
reasonable need to know the same, and except as required by law, not to release
or disclose it to any third parties, without the prior written consent of the
disclosing Party. The obligations set forth in this Subsection shall not apply
to any information that: (a) is now or hereafter in the public domain or
otherwise becomes available to the public other than by breach of this Agreement
by the receiving Party, (b) has been rightfully in the receiving Party's
possession prior to receipt from the disclosing Party, (c) is rightfully
received by the receiving Party from a third party without restriction on
disclosure, (d) is independently developed by the receiving Party, (e) is
authorized in writing by the disclosing Party to be released or disclosed, or
(f) subject to the receiving Party's compliance with Section 15.4 below, is
required to be disclosed by the receiving Party pursuant to law, governmental
regulation or judicial order.

                  15.1.2 All Proprietary Information and any copies thereof
shall remain the property of the disclosing Party, and no license or other
rights therein is granted or implied hereby. The receiving Party shall, upon the
disclosing Party's request, return the original and all copies of tangible
Proprietary Information. Notwithstanding the foregoing, any of the Buyers'
Proprietary Information that is transmitted or disclosed to Seller by a Buyer
(or, in the case of TSMC, TSMC or its customer) in accordance with the
provisions of Subsection 15.1.1 and is thereafter incorporated into a Process or
manufacturing method used in the Foundry, may be retained by Seller in the form
so incorporated or used. Seller shall have the nonexclusive right to use such
Proprietary Information as so incorporated or used, and as such incorporation or
use may be modified or improved. TSMC shall obtain its customer's permission to
extend to Seller such nonexclusive right with respect to Proprietary Information
(of TSMC) provided by the customer.

         15.2  OTHER CONFIDENTIALITY AGREEMENTS.  This Article is supplemental
to and not in limitation of any confidentiality agreements to which the Parties
are signatories.

         15.3  CONFIDENTIALITY AGREEMENTS FOR SPECIFIC PERSONS. Any Buyer's
officers, directors, employees, agents, representatives or contractors who are
assigned to or visit the Foundry pursuant to Section 5.9 shall execute and
deliver a confidentiality agreement in form of Exhibit "I" attached hereto.

         15.4  THIRD PARTY REQUEST FOR INFORMATION. Except as otherwise provided
herein, each Party shall immediately notify the other of any private or
governmental request for Proprietary Information or documents relating to Proven
Products, Risk Wafers, Test Wafers or this Agreement; provided, however, that
(a) a request for documents relating to Proven Products, Risk Wafers, or Test
Wafers received by any Buyer from its customers or prospective customers in the
ordinary course of business where disclosure of such information would not
contain Proprietary Information of Seller or any other Buyer shall be excluded
from the provisions of this Section 15.4 and (b) a Buyer may disclose to its
customer, upon the customer's request in the ordinary course of business, Design
Rules or reliability data relating to Proven Products, Risk Wafers, or Test
Wafers, if (i) the Buyer and its customer enter into a confidentiality agreement
substantially in the form of Exhibit "K" and (ii) the Buyer notifies Seller of
the disclosure before or promptly after it. Each Party shall have the right to
participate in the other Party's response to any such request. In the event that
a Party receives any subpoena or other legal process requiring the production of
information, documents, data, work papers, reports, or other materials relating
to Proprietary Information, Proven Products, Risk Wafers, Test Wafers or this
Agreement, that Party shall:

               15.4.1  Give the affected Party, if possible, the opportunity to
participate in quashing, modifying or otherwise responding to any compulsory
process in an appropriate and timely manner; and

               15.4.2  Cooperate fully with the affected Party's efforts to
narrow the scope of any such compulsory process, to obtain a protective order
limiting the use or disclosure of the information sought, or in any other lawful
way to obtain continued protection of such information.

         15.5  REPORTING LOSS, THEFT OR MISAPPROPRIATION. If any Party becomes
aware of the loss, theft or misappropriation of Proprietary Information which is
in that Party's possession or control, that Party shall notify the other Party
whose Proprietary Information has been lost, stolen or misappropriated within
five (5) days after the discovery of such loss, theft or misappropriation.

                               EXPORT COMPLIANCE

         16.1  COMPLIANCE WITH EXPORT ADMINISTRATION REGULATIONS.  Each Party
agrees that, unless prior authorization is obtained from the United States
Government, it shall not knowingly:

               (a)  Re-export, directly or indirectly, any technical data (as
defined in Part 779 of the Export Administration Regulations of the Department
of Commerce) received from the other Buyers, Seller, or their respective
Affiliates or customers to; or

               (b)  Disclose such technical data for use in; or


                                       35
                                                       FUTURE PURCHASE AGREEMENT
   139
               (c)  Export, directly or indirectly, any Proven Product, Risk
Wafer, Test Wafers, product containing a Proven Product, Risk Wafer, Test Wafers
or such technical data to any destination or country to which the re-export or
release of technical data or export of Proven Products, Risk Wafers, Test Wafers
or products containing Proven Products, Risk Wafers, Test Wafers or technical
data is prohibited by U.S. laws and regulations. These assurances are furnished
by each Party in compliance with Part 779 Technical Data of the Export
Administration Regulations of the Department of Commerce of the Government of
the United States of America.

         16.2  U.S. EXPORT LICENSES. Each Party further agrees to obtain any
necessary export license or other documentation prior to exportation of any
Proven Product, Test Wafer or Risk Wafer, product containing a Proven Product,
Test Wafer or Risk Wafer, or technical data acquired from any other Party, its
Affiliates, or their respective customers hereunder. Accordingly, each Party
shall not sell, export, re-export, transfer, divert or otherwise dispose of any
Proven Product, Test Wafer or Risk Wafer or a product containing a Proven
Product, Test Wafer or Risk Wafer, directly or indirectly, to any person, entity
or country to which such disposal is prohibited by the laws or regulations of
the United States. Further, each Party shall notify any person or entity
obtaining any such Proven Product, Test Wafer or Risk Wafer or a product
containing a Proven Product, Test Wafer or Risk Wafer from such Party of the
need to comply with such laws or regulations. Each Party shall secure at its
sole expense such licenses and export and import documents as are necessary for
the Party to fulfill its obligations hereunder.

         16.3  REPUBLIC OF CHINA EXPORT REGULATIONS. If Seller or Buyers are
subject to the national export control regulations of the Republic of China,
each Party shall take all appropriate measures to comply with such applicable
regulations.

                                   ARTICLE 17
                         DISPUTE RESOLUTION; ARBITRATION

         17.1  NEGOTIATION BETWEEN EXECUTIVES. The Parties shall attempt in good
faith to resolve any dispute, controversy or claim ("Dispute") arising out of or
relating to this Agreement promptly by negotiations between executives who have
authority to settle the Dispute. Any Party may give the other Parties written
notice of any Dispute not resolved in the normal course of business. Within
twenty (20) days after delivery of such a notice, executives of the Parties who
have authority to settle the Dispute shall meet at a mutually acceptable time
and place, and thereafter as often as they reasonably deem necessary, to attempt
to resolve the Dispute. If the matter has not been resolved within thirty (30)
days after such notice, unless extended by the agreement of the Parties in
writing (the "Negotiation Period"), the matter shall be subject to mediation as
provided in Section 17.2. If a Party intends to be accompanied at a meeting by
an attorney, the other Parties shall be given at least three (3) Business Days'
notice of such intention and may also be accompanied by an attorney. All
negotiations pursuant to this provision are confidential and shall be treated as
compromise and settlement negotiations for purpose of the United States Federal
Rules of Evidence and state rules of evidence.

         17.2  MEDIATION. Any Dispute not settled pursuant to Section 17.1 shall
be submitted to mediation administered by the American Arbitration Association
under its Commercial Mediation Rules (such mediation, "Mediation"), before
resorting to arbitration as hereinafter provided. The Mediation shall be
completed within forty-five (45) days of its initiation pursuant to the
Commercial Mediation rules, unless the Parties otherwise agree. Executives of
the Parties with authority to resolve the Dispute shall participate in the
Mediation. The Mediation shall take place in San Jose, California. The Parties
shall attempt in good faith to reach agreement on the appointment of a mediator.
If they cannot so agree, the mediator shall be appointed pursuant to the
Commercial Mediation Rules; provided, however, that the mediator appointed shall
have a background in the semiconductor industry. The Parties shall each pay
their own expenses of Mediation, including attorney's fees, and shall share
equally the mediator's fees and expenses.

         17.3  CLAIMS SUBJECT TO ARBITRATION. Except as otherwise specifically
provided herein, any Dispute arising out of or relating to this Agreement, or
the breach or termination hereof, and not resolved pursuant to Section 17.1 or
Section 17.2 shall be resolved by binding arbitration in accordance with the
Federal Arbitration Act, 9 U.S.C. Sections 1 et seq. (the "FAA"), and the
Commercial Arbitration Rules, and where the amount in controversy exceeds
$1,000,000, the Supplementary Procedures for Large Complex Disputes, of the AAA
(collectively, the "Rules"). In the event of a conflict between the FAA and the
Rules, the Rules shall govern. In the event of a conflict between this Article
and the FAA or the Rules, this Article shall govern. A court of competent
jurisdiction, upon application from any Party, may relieve the Parties of their
duty to arbitrate Disputes in whole or in part, or may stay any arbitration
hereunder in whole or in part, if ongoing litigation between one or more of the
Parties and a third party (or parties) involves issues of fact or law common
with those subject to arbitration hereunder and there exists the possibility of
inconsistent judgments if such relief is not granted. Each Party reserves the
right to file with a court of competent jurisdiction an application for
temporary or preliminary injunctive relief, a protective order or other
appropriate provisional remedy on grounds that (a) the arbitration award to
which the applicant may be entitled may be rendered ineffectual in the absence
of such relief; or (b) in the event of a breach or threatened breach of the
provisions of Subsection 15.1.1 prohibiting disclosure of Proprietary
Information.

         17.4  VENUE.  The venue for any arbitration proceeding hereunder shall 
be San Jose, California.

         17.5  SELECTION OF ARBITRATOR AND DETERMINATION OF CONTROVERSIES.

                 17.5.1 Any Dispute subject to arbitration shall be submitted
to a single neutral arbitrator, who, unless otherwise agreed by the Parties,
shall be a retired judge or other lawyer who is a member of the arbitration
panel of the Judicial Arbitration and Mediation Service ("JAMS") or the national
panel of arbitrators of the AAA, and who has substantial experience in the area
of the Dispute. The Parties shall confer concerning the selection of AAA or JAMS
with the objective of selecting one or the other within thirty (30) days of the
conclusion of the Mediation; provided, however, that, if all Parties to the
Dispute do not agree on one or the other within such thirty (30) day period, the
Dispute initially will be submitted simultaneously to both 


                                       37
                                                       FUTURE PURCHASE AGREEMENT
   141
AAA and JAMS for the sole purpose of picking the arbitrator. If the Parties
select JAMS, then the term "Rules" as used herein shall mean the then-prevailing
JAMS rules. The AAA (or JAMS, as the case may be) simultaneously shall submit to
each Party an identical list of five proposed qualified arbitrators drawn from
the applicable panel of commercial arbitrators. If the Parties are unable to
agree upon an arbitrator within thirty (30) days from the date that AAA (or
JAMS, as the case may be) submits such list to each Party, then AAA (or JAMS, as
the case may be) shall simultaneously submit to each Party a second list of five
additional proposed qualified arbitrators drawn from the applicable panel of
commercial arbitrators. If for any reason, the appointment of an arbitrator
cannot be made from either list, AAA (or JAMS, as the case may be) may make the
appointment from among other qualified members of the panel without the
submission of additional lists to the Parties. If the Dispute is initially
submitted to both AAA and JAMS for the purpose of picking the arbitrator, then
both AAA and JAMS simultaneously shall submit to each Party lists of five
proposed qualified arbitrators drawn from the applicable panel (with each Party
receiving the identical list from AAA and the identical list from JAMS), and if
the Parties are unable to agree upon an arbitrator within thirty (30) days from
the date that both AAA and JAMS submit the first such lists to each Party, then
AAA and JAMS simultaneously shall submit to each Party second lists of five
additional proposed qualified arbitrators (with each Party receiving an
identical second list from AAA and an identical second list from JAMS). If the
Parties for any reason are unable to select an arbitrator from the first and
second lists submitted by AAA and by JAMS, then a majority of the Parties shall
select to arbitrate with either AAA or with JAMS, and the arbitration
organization so selected shall make the appointment from among other qualified
members of the arbitration panel of that organization without the submission of
additional lists to the Parties. Where the Parties have initially submitted the
Dispute to both JAMS and AAA, then once an arbitrator has been appointed, the
arbitration proceeding will be terminated with the arbitration organization that
has not been selected and the Parties shall equally share the costs and fees of
the arbitration organization so terminated. If for any reason the Parties to the
Dispute have not selected an arbitrator within ninety (90) days of the
conclusion of the Mediation, then the arbitration shall be conducted with the
AAA. No matter how selected, the arbitrator shall have no prior or existing
affiliation or relationship with any Party or its counsel and shall sign an oath
of impartiality upon appointment.

                  17.5.2  The Parties shall be entitled to obtain pre-hearing 
discovery through depositions and requests for the inspection and copying of
documents and other items upon reasonable notice and to obtain the issuance of a
subpoena duces tecum therefor in accordance with applicable law, including
without limitation, 9 U.S.C. Section 7 and (notwithstanding Section 1297.17 of
the California Code of Civil Procedure) Section 1283.05 of the California Code
of Civil Procedure; provided that depositions shall not be taken unless leave to
do so is first granted by the arbitrator. As between the Parties, the arbitrator
shall have the power to enforce the rights, remedies, procedures, duties,
liabilities and obligations of discovery by the imposition of the same terms,
conditions, consequences, sanctions and penalties as may be imposed in like
circumstances in a civil action by a U.S. Federal court.

         17.6  ARBITRATION AWARD AND JUDICIAL REVIEW. The arbitrator, in 
deciding any Dispute, shall base his decision on the record and in accordance
with this Agreement and applicable law.

   142
In no event shall the arbitrator make any ruling, finding or award that does not
conform to the terms and conditions of this Agreement, is not supported by the
weight of the evidence, or is contrary to statute, administrative regulations or
established judicial precedents. The arbitration award shall be a factually
detailed, reasoned opinion stating the arbitrator's findings of fact and
conclusions of law. Unless the arbitrator for good cause determines otherwise,
the final award shall include attorneys' fees, costs and expenses of the
prevailing Party, including expert and nonexpert witness fees and the prevailing
Party's share of the administrative fee and the arbitrator's fees and expenses,
if any. Notwithstanding any other provisions hereof, the arbitrator shall have
no jurisdiction to award damages in contravention of Article 10 hereof. The
arbitration award shall be subject to judicial review in accordance with 9
U.S.C. Sections 10-12; provided, however, that the arbitration award shall
also be vacated to the extent that the arbitrator exceeds his or her authority
as set forth in this Section 17.6, and, on balance, the Party seeking vacation
of the award has been materially and adversely affected thereby. Judgment may be
entered on the award by a United States District Court in accordance with 9
U.S.C. Section 9.

         17.7  CONSOLIDATION AND JOINDER. It is the Parties' intent to avoid, to
the maximum extent possible, having to arbitrate claims arising out of this
Agreement in more than one proceeding. Accordingly, the Parties hereby consent
to the joinder of any person or entity sought to be joined where such or person
or entity is substantially involved in a common question of fact or law and its
or his presence is required for complete relief to be accorded in an arbitration
proceeding under this Article 17.

                                   ARTICLE 18
                               GENERAL PROVISIONS

         18.1  SEVERABILITY. If any provision of this Agreement is or becomes or
is deemed invalid, illegal or unenforceable in any jurisdiction, such provision
shall be deemed amended to conform to applicable laws so as to be valid and
enforceable or, if it cannot be so amended without materially altering the
intention of the Parties, it shall be stricken and the remainder of this
Agreement shall remain in full force and effect.

         18.2  NEUTRAL INTERPRETATION; WAIVER OF CONFLICT. Each Party has
received independent legal advice from its attorneys with respect to the
advisability of executing this Agreement and the meaning of the provisions
hereof. Each Party waives any real, apparent, possible or inchoate conflict in
connection with, arising out of or resulting from the representation of Seller,
TSMC and its Affiliates by the same law firm relative to the negotiation and
execution of this Agreement and any confidentiality agreement provided for

meaning, and not for or against any Party based upon any attribution to such
Party as the source of the language in question.

communications required or permitted to be given to a Party hereunder shall be

and contain the entire agreement of the Parties. With the exception of the LLC
Agreement, this Agreement supersedes any and all prior or contemporaneous
negotiations, correspondence, understandings and agreements among the Parties,
written or oral, respecting the subject matter hereof. In case of any conflict
between the LLC Agreement and this Agreement, the LLC Agreement shall govern.

         18.7  WAIVER; AMENDMENT. No waiver of any provision of this Agreement
shall be effective unless and until made in writing and signed by the Party to
be charged. No waiver, forbearance or failure by any Party hereto of its right
to enforce any provision of this Agreement shall constitute a waiver or estoppel
of such Party's right to enforce any other provision of this Agreement or a
continuing waiver by such Party of compliance with any provision. Any amendment
or modification of this Agreement shall be by unanimous written consent of the
Parties.

         18.8  COOPERATION.  Each Party shall cooperate with the other Parties

Confidential Information (as defined below) regarding the Disclosing Party's
business operations and products (the "Business"); and

         WHEREAS, the Disclosing Party's grant of access to the Foundry and its
disclosure of certain Confidential Information regarding the Disclosing Party's
Business is for the following purpose:__________________________________ (the
"Purpose"); and

         WHEREAS, the Disclosing Party desires to maintain the secrecy of its
Confidential Information and accordingly has requested that the Receiving Party
execute this Agreement as a condition precedent to the granting of access to the
Foundry and the disclosure of such information to the Receiving Party; and

        WHEREAS, this Agreement is made and entered into pursuant to that
certain Second Purchase Agreement by and between the Disclosing Party and the
Buyers named as parties therein, dated as of           (the "Purchase

information to the other party's engineers, technicians and personnel so long as
they execute and deliver a copy of this Agreement. 

         NOW THEREFORE, in consideration of the above premises, and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1.       DEFINITION OF CONFIDENTIAL INFORMATION

analyses, compilations, presentations or other documents (including materials
prepared by the Receiving Party), which contain or otherwise reflect such
information. Confidential Information shall include, if applicable, any

documents that the Disclosing Party requires to be deleted.

         4.       DISCLOSURE OF CONFIDENTIAL INFORMATION

                  Without the prior consent of the Disclosing Party, the
Receiving Party shall not disclose to any person (a) the fact that the
Confidential Information has been made available to the Receiving Party or that
the Receiving Party has inspected any portion of the Confidential Information,
or (b) any of the terms, conditions or other facts with respect to the Business
or the Disclosing Party, except to the extent the foregoing is required to be
disclosed by the Receiving Party pursuant to law,


                                       I-2             FUTURE PURCHASE AGREEMENT

   158
governmental regulation or judicial order, provided that written notice is given
to the Disclosing Party prior to the required disclosure. The fact that such
information has been delivered to the Receiving Party and any discussions
regarding the Business or the Disclosing Party, are deemed Confidential
Information for the purposes of this Agreement, except to the extent the
foregoing is required to be disclosed by the Receiving Party pursuant to law,
governmental regulation or judicial order, provided that written notice is given
to the Disclosing Party prior to the required disclosure.

         5.       DESTRUCTION OR RETURN OF CONFIDENTIAL INFORMATION

                  Upon request from the Disclosing Party to the Receiving Party
(a) the Receiving Party shall either destroy or return to the Disclosing Party
all Confidential Information which is in tangible form, including any copies of
which the Receiving Party may have made, destroy all abstracts, summaries
thereof or references thereto in the documents of the Receiving Party, and
certify to Disclosing Party that this has been done, and (b) the Receiving Party
shall not use any of the Confidential Information with respect to, or in
furtherance of, any of its businesses (or, if applicable, the business of its
employer) or in the business of anyone else, whether or not in competition with
the Disclosing Party, or for any other purpose whatsoever.

         6.       INDEMNIFICATION

                  The Receiving Party hereby agrees to indemnify, defend and
hold harmless the Disclosing Party from any damages, loss, cost or liability
(including legal fees and costs of enforcing this indemnity) arising out of or
resulting from any unauthorized use or disclosure by the Receiving Party of the
Confidential Information.

         7.       REMEDIES

                  Receiving Party acknowledges that money damages would be both
incalculable and an insufficient remedy for any breach of this Agreement by a
Receiving Party, and that such breach would cause Disclosing Party irreparable
harm. In addition to all other remedies available to Disclosing Party at law, in
equity or under this Agreement, the Disclosing Party will be entitled to
specific performance and injunctive or other equitable relief as a remedy for
any such breach, and the breaching party agrees to waive any requirement of
receiving or posting of any bond in connection with such remedy. Each party
agrees and consents to the entry of a preliminary injunction or protective order
by any court of competent jurisdiction upon a showing by the Disclosing Party
that its Confidential Information is being used or disclosed contrary to the
provisions of this Agreement. The arbitration provisions of Sections 17.3
through 17.7 of the Purchase Agreement shall not apply to any temporary
restraining order, preliminary injunctive relief, protective order or other
provisional remedy sought to prohibit a breach or threatened breach of the
provisions of this Agreement.

   159
         8.       NO LICENSE

                  This Agreement does not imply any license to the Receiving
Party (or, if applicable, its employer) of Disclosing Party's Confidential
Information or any of its patents, copyrights, trademarks, mask-work rights or
applications therefor. All proprietary rights, including but not limited to
patent rights and trade and industrial secrets, in and to the Confidential
Information shall remain the Disclosing Party's property.

         9.       ADDITIONAL AGREEMENT IF RECEIVING PARTY IS A BUSINESS
                  ORGANIZATION

                  If the Receiving Party is a corporation, limited liability
company, or other business organization, it agrees (a) that it shall hold all
Confidential Information it receives from the Disclosing Party in strict
confidence and with the same degree of care that Receiving Party gives to
Receiving Party's own proprietary and confidential information, but not less
than a reasonable degree of care, and shall not disclose such Confidential
Information to others, except as may be required by law; (b) Receiving Party's
covenants and agreements set forth in this Agreement shall be binding upon its
officers, directors, employees, representatives and agents; and (c) the
Receiving Party shall cause its officers, directors, employees, representatives
and agents to abide by the provisions of this Agreement. Notwithstanding the
provisions of paragraph 4 above, the Receiving Party may disclose Confidential
Information without the prior consent of the Disclosing Party to its officers,
directors and employees who have a need to know such information in order to
perform their duties; provided, however, that each person to whom the
Confidential Information is disclosed must be advised of its confidential nature
and of the terms of this Agreement and must have entered into a written
agreement with the Receiving Party that obligates such person to abide by such
terms (a copy of which must be delivered to the Disclosing Party upon the
Disclosing Party's request).

         10.               WAIVERS

                  It is understood and agreed that no failure or delay by the
Disclosing Party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise thereof
preclude any or further exercise or the exercise of any right, power or
privilege hereunder.

         11.               SEVERABILITY

                  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

         12.               CONSENT TO JURISDICTION; GOVERNING LAW

                  Except as otherwise provided herein, all disputes, differences
or controversies arising from this Agreement shall be settled by arbitration in
accordance with and pursuant to the arbitration provisions set forth in Sections
17.3 through 17.7 of the Purchase Agreement, a copy of which


                                       I-4             FUTURE PURCHASE AGREEMENT

   160
Sections 17.3 through 17.7 are attached hereto as Exhibit "A" and is
incorporated by reference herein. Each Party reserves the right to file with a
court of competent jurisdiction an application for temporary or preliminary
injunctive relief, a protective order or other appropriate provisional remedy
(a) on grounds that the arbitration award to which the applicant may be entitled
may be rendered ineffectual in the absence of such relief, or (b) in the event
of a breach or threatened breach of the provisions of this Agreement prohibiting
disclosure of Confidential Information. This Agreement shall be governed by and
construed in accordance with the laws of Delaware.

         13.               DURATION

                  This Agreement shall become effective upon execution and
delivery hereof and shall continue in full force and effect for so long as the
Disclosing Party shall exist; provided, however, that the obligation of the
Receiving Party under paragraphs 3, 4, 5, 6, 7, 9 and 12 shall survive
indefinitely.

         14.               ENTIRE AGREEMENT; SURVIVAL; SUCCESSORS AND ASSIGNS

                  This Agreement contains the entire understanding of the
parties hereto concerning the subject matter hereof and supersedes any prior
agreement or understanding of the parties. This Agreement shall survive the
execution of any other definitive document between the parties hereto and may
not be modified except in writing, duly signed by the party against whom
enforcement is sought. This Agreement shall inure to the benefit of and is
binding upon each of the parties hereto and their respective heirs, successors,
assigns and personal representatives.

         15.               COUNTERPARTS.

                  This Agreement is expected to be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument. The facsimile signature
of a party to this Agreement is and shall be deemed to be an original execution
and is binding.

                    EXHIBIT "A" TO CONFIDENTIALITY AGREEMENT

                                   ARBITRATION

         Shown below is a copy of Sections 17.3 to 17.7 of that certain Purchase
Agreement, dated as of           , by and among WaferTech, LLC, as Seller, and
[TSMC Development, Inc., Analog Devices, Inc., Altera Corporation, and
Integrated Silicon Solutions, Inc.], as Buyers (such copy, the "Copy"). The Copy
is an exact copy of the Purchase Agreement except for the insertion of the
phrase "by negotiation or mediation between the Parties" in the first sentence
of Section 17.3 of the Purchase Agreement, replacing a reference to Sections
17.1 to 17.2 of that agreement, which Sections are not applicable to this
Agreement. All references to Articles, Sections, and Subsections in the Copy are
to corresponding subdivisions of the Purchase Agreement. All undefined
capitalized terms in the Copy have the meanings given in the Purchase 
Agreement. 

         17.3 CLAIMS SUBJECT TO ARBITRATION. Except as otherwise specifically
provided herein, any Dispute arising out of or relating to this Agreement, or
the breach or termination hereof, and not resolved by negotiation or mediation
between the Parties shall be resolved by binding arbitration in accordance with
the Federal Arbitration Act, 9 U.S.C. Sections 1 et seq. (the "FAA"), and
the Commercial Arbitration Rules, and where the amount in controversy exceeds
$1,000,000, the Supplementary Procedures for Large Complex Disputes, of the AAA
(collectively, the "Rules"). In the event of a conflict between the FAA and the
Rules, the Rules shall govern. In the event of a conflict between this Article
and the FAA or the Rules, this Article shall govern. A court of competent
jurisdiction, upon application from any Party, may relieve the Parties of their
duty to arbitrate Disputes in whole or in part, or may stay any arbitration
hereunder in whole or in part, if ongoing litigation between one or more of the
Parties and a third party (or parties) involves issues of fact or law common
with those subject to arbitration hereunder and there exists the possibility of
inconsistent judgments if such relief is not granted. Each Party reserves the
right to file with a court of competent jurisdiction an application for
temporary or preliminary injunctive relief, a protective order or other
appropriate provisional remedy on grounds that (a) the arbitration award to
which the applicant may be entitled may be rendered ineffectual in the absence
of such relief; or (b) in the event of a breach or threatened breach of the
provisions of Subsection 15.1.1 prohibiting disclosure of Proprietary
Information.

         17.4 VENUE. The venue for any arbitration proceeding hereunder shall be
San Jose, California.

         17.5 SELECTION OF ARBITRATOR AND DETERMINATION OF CONTROVERSIES.

                  17.5.1 Any Dispute subject to arbitration shall be submitted
to a single neutral arbitrator, who, unless otherwise agreed by the Parties,
shall be a retired judge or other lawyer who is a member of the arbitration
panel of the Judicial Arbitration and Mediation Service ("JAMS") or the national
panel of arbitrators of the AAA, and who has substantial experience in the area
of the Dispute. The Parties shall confer concerning the selection of AAA or JAMS
with the objective of selecting one or the other within thirty (30) days of the
conclusion of the Mediation; provided,


                                       I-7             FUTURE PURCHASE AGREEMENT

   163
however, that, if all Parties to the Dispute do not agree on one or the other
within such thirty (30) day period, the Dispute initially will be submitted
simultaneously to both AAA and JAMS for the sole purpose of picking the
arbitrator. If the Parties select JAMS, then the term "Rules" as used herein
shall mean the then-prevailing JAMS rules. The AAA (or JAMS, as the case may be)
simultaneously shall submit to each Party lists of five proposed qualified
arbitrators drawn from the applicable panel of commercial arbitrators. If the
Parties are unable to agree upon an arbitrator within thirty (30) days from the
date that AAA (or JAMS, as the case may be) submits such list to each Party,
then AAA (or JAMS, as the case may be) shall simultaneously submit to each Party
a second list of five additional proposed qualified arbitrators drawn from the
applicable panel of commercial arbitrators. If for any reason, the appointment
of an arbitrator cannot be made from either list, AAA (or JAMS, as the case may
be) may make the appointment from among other qualified members of the panel
without the submission of additional lists to the Parties. If the Dispute is
initially submitted to both AAA and JAMS for the purpose of picking the
arbitrator, then both AAA and JAMS simultaneously shall submit to each Party
lists of five proposed qualified arbitrators drawn from the applicable panel
(with each Party receiving the identical list from AAA and the identical list
from JAMS), and if the Parties are unable to agree upon an arbitrator within
thirty (30) days from the date that both AAA and JAMS submit the first such
lists to each Party, then AAA and JAMS simultaneously shall submit to each Party
second lists of five additional proposed qualified arbitrators (with each Party
receiving an identical second list from AAA and an identical second list from
JAMS). If the Parties for any reason are unable to select an arbitrator from the
first and second lists submitted by AAA and by JAMS, then a majority of the
Parties shall select to arbitrate with either AAA or with JAMS, and the
arbitration organization so selected shall make the appointment from among other
qualified members of the arbitration panel of that organization without the
submission of additional lists to the Parties. Where the Parties have initially
submitted the Dispute to both JAMS and AAA, then once an arbitrator has been
appointed, the arbitration proceeding will be terminated with the arbitration
organization that has not been selected and the Parties shall equally share the
costs and fees of the arbitration organization so terminated. If for any reason
the Parties to the Dispute have not selected an arbitrator within ninety (90)
days of the conclusion of the Mediation, then the arbitration shall be conducted
with the AAA. No matter how selected, the arbitrator shall have no prior or
existing affiliation or relationship with any Party or its counsel and shall
sign an oath of impartiality upon appointment.

                  17.5.2 The Parties shall be entitled to obtain pre-hearing
discovery through depositions and requests for the inspection and copying of
documents and other items upon reasonable notice and to obtain the issuance of a
subpoena duces tecum therefor in accordance with applicable law, including
without limitation, 9 U.S.C. Section 7 and (notwithstanding Section 1297.17 of
the California Code of Civil Procedure) Section 1283.05 of the California Code
of Civil Procedure; provided that depositions shall not be taken unless leave to
do so is first granted by the arbitrator. As between the Parties, the arbitrator
shall have the power to enforce the rights, remedies, procedures, duties,
liabilities and obligations of discovery by the imposition of the same terms,
conditions, consequences, sanctions and penalties as may be imposed in like
circumstances in a civil action by a U.S. Federal court.

         17.6 ARBITRATION AWARD AND JUDICIAL REVIEW. The arbitrator, in deciding
any Dispute, shall base his decision on the record and in accordance with this
Agreement and applicable law. In no event shall the arbitrator make any ruling,
finding or award that does not conform to the terms and conditions of this
Agreement, is not supported by the weight of the evidence, or is contrary to
statute, administrative regulations or established judicial precedents. The
arbitration award shall be a factually detailed, reasoned opinion stating the
arbitrator's findings of fact and conclusions of law. Unless the arbitrator for
good cause determines otherwise, the final award shall include attorneys' fees,
costs and expenses of the prevailing Party, including expert and nonexpert
witness fees and the prevailing Party's share of the administrative fee and the
arbitrator's fees and expenses, if any. Notwithstanding any other provisions
hereof, the arbitrator shall have no jurisdiction to award damages in
contravention of Article 10 hereof. The arbitration award shall be subject to
judicial review in accordance with 9 U.S.C. Sections 10-12; provided, however,
that the arbitration award shall also be vacated to the extent that the
arbitrator exceeds his or her authority as set forth in this Section 17.6, and,
on balance, the Party seeking vacation of the award has been materially and
adversely affected thereby. Judgment may be entered on the award by a United
States District Court in accordance with 9 U.S.C. Section 9.

         17.7 CONSOLIDATION AND JOINDER. It is the Parties' intent to avoid, to
the maximum extent possible, having to arbitrate claims arising out of this
Agreement in more than one proceeding. Accordingly, the Parties hereby consent
to the joinder of any person or entity sought to be joined where such or person
or entity is substantially involved in a common question of fact or law and its
or his presence is required for complete relief to be accorded in an arbitration
proceeding under this Article 17.

                                   EXHIBIT "J"

                             METHOD FOR APPORTIONING
                     THE UNUSED MINIMUM PURCHASE ALLOCATION

         The Unused Minimum Purchase Allocation (the "UMPA") will be apportioned
among the Non-Defaulting Buyers (as defined in Subsection 3.4.1) in the
following manner, unless the Non-Defaulting Buyers otherwise agree. Following
the Defaulting Buyer's (as defined in Subsection 3.4.1) written notice to the
Non-Defaulting Buyers, as provided in Subsection 3.4.1, each Non-Defaulting
Buyer will notify the others of the proportion (between zero and one inclusive)
of the UMPA the Non-Defaulting Buyer elects to take (in this exhibit, such
proportion, as may be reduced by the method below, the Non-Defaulting Buyer's
"elected proportion," and the part (in Wafer Equivalents) of the UMPA
corresponding to the elected proportion, the Buyer's "election"). If a
Non-Defaulting Buyer fails to elect any part of the UMPA within thirty (30) days
following receipt of the Defaulting Buyer's written notice, the Non-Defaulting
Buyer is considered to have elected to take none of the UMPA.

NONTECHNICAL DESCRIPTION OF THE METHOD

         If the Non-Defaulting Buyers elect in the aggregate to take all or only
part of the UMPA, each Non-Defaulting Buyer will be allowed to take exactly the
amount it elects. If, on the other hand, the Non-Defaulting Buyers
"oversubscribe" to the UMPA, some of their elections will be reduced as required
until their aggregate elections (the "election total") equal the UMPA. (Since a
Non-Defaulting Buyer's election can be reduced, but will not be increased, each
Non-Defaulting Buyer should elect the maximum amount of the UMPA the Buyer is
willing to take.)

         In the oversubscribed case, the method will attempt to accommodate each
NonDefaulting Buyer's election within the available UMPA, yet will not permit
one Buyer to take more than a given multiple of its Basic Purchase Share to the
extent that other Buyers also seek at least the same multiple of their Basic
Purchase Shares. This fairness principal is operationalized through the
"election ratio," i.e., the ratio of a Buyer's elected proportion to its Basic
Purchase Share. For example, if one Buyer has an election ratio of 2, while
another has an election ratio of 1, the first Buyer has elected twice as much as
its Basic Purchase Share, while the second Buyer has elected its Basic Purchase
Share.

         Any Non-Defaulting Buyer whose elected proportion is less than or equal
to the quotient of (a) the Buyer's Basic Purchase Share divided by (b) the sum
of the Basic Purchase Shares among the Non-Defaulting Buyers will be able to
take the Buyer's election without reduction.

         Among the remaining Non-Defaulting Buyers, the method reduces the
elections of Buyers whose election ratios are higher than others' before
reducing the others' elections and continues until the election total is reduced
to the UMPA or until the election ratios among such Buyers are all equal. If the
elections of several Buyers with equal election ratios are to be reduced during
any step of the


                                       J-1
                                                       FUTURE PURCHASE AGREEMENT
   166
process, those elected proportions are reduced by the same percentage so as to
preserve the equality of those Buyers' election ratios after the reduction.
(When all the election ratios among the Buyers are equal, the election of each
such Buyer is proportionate to its Basic Purchase Share.) If the election total
still exceeds the UMPA after all election ratios among such Buyers are
equalized, the election of each such Buyer is further reduced by a percentage
(identical for each such Buyer) which yields an election total equal to the
UMPA.

         For numerical examples of the method, see the section "Numerical
Examples" below.

MATHEMATICAL DESCRIPTION OF THE METHOD

         A.       ELECTION TOTAL LESS THAN OR EQUAL TO THE UMPA. If the election
total is less than or equal to the UMPA, then each Non-Defaulting Buyer will
take its election without further adjustment.

         B.       ELECTION TOTAL GREATER THAN THE UMPA. If the election total
exceeds the UMPA, then the following procedure is used to reduce the election
total to the UMPA:

         Step 1: Assign to each Non-Defaulting Buyer whose elected proportion is
less than or equal to the ratio of (a) its Basic Purchase Share to (b) the sum
of the Non-Defaulting Buyers' Basic Purchase Shares that Buyer's election
without reduction.

         Step 2: List the remaining Non-Defaulting Buyers in decreasing order of
their election ratios. Assume for purposes of the remaining steps that there are
four Buyers and thus at most three Non-Defaulting Buyers on the list. The steps
below can be generalized to the case where there are more than three
Non-Defaulting Buyers on the list.

         Step 3:

                  (a) If only one Buyer is on the list, reduce its election
         until the election total equals the UMPA.(1) The process stops at this
         step and the Non-Defaulting Buyers will take their respective elections
         (as adjusted) at the completion of this step.

                  (b) If two or more Buyers are on the list, reduce the first
         Buyer's election until (1) the Buyer's election ratio equals that of
         the second Buyer's or (2) the election total equals the UMPA.(2) If the
         election total equals the UMPA, the process stops at this step and the
         Buyers on the list will take their respective elections at the
         completion of this step; otherwise, the process continues to the next
         step.

         Step 4 (when two or more Buyers are on the list):

- -------------
         (1) The Buyer's election will be reduced to (1) the UMPA less (2) the
         sum of the other Non-Defaulting Buyers' elections.

         (2) The first Buyer's election will be reduced to the greater of (1)
         (a) the UMPA less (b) the sum of the other Non-Defaulting Buyers'
         elections or (2) the product of (a) the UMPA, (b) the Buyer's Basic
         Purchase Share, and (c) the election ratio of the second Buyer on the
         list.


                                       J-2
                                                       FUTURE PURCHASE AGREEMENT
   167
                  (a) If there are two Buyers on the list, reduce each of their
         elections (as adjusted through step 3) by the same factor until the
         election total equals the UMPA.(3) The process stops at this step and
         the Buyers on the list will take their respective elections (as
         adjusted) at the completion of this step.

                  (b) If there are three Buyers on the list, reduce each of the
         first two Buyers' elections (as adjusted through step 3) by the same
         factor until (1) the two Buyers' election ratios equal that of the
         third Buyer's or (2) the election total equals the UMPA.(4) If the
         election total equals the UMPA, the process stops at this step and the
         Buyers on the list will take their respective elections at the
         completion of this step; otherwise, the process continues to the next
         step.

         Step 5 (when there are three Buyers on the list): Reduce each of the
listed Buyers' elections (as adjusted through step 4) by the same factor until
the election total equals the UMPA.(5)

NUMERICAL EXAMPLES

         As an illustration of the above method, suppose that the Buyers are
TSMC and three Regular Buyers (referred to below as Buyers No. 1 to No. 4,
respectively), with Basic Purchase Shares of 60%, 18%, 18%, and 4%,
respectively. Suppose further that Buyer No. 2 with an 18% Basic Purchase Share
is a Defaulting Buyer. Finally, suppose that the UMPA equals 100 Wafer
Equivalents. The table below shows three cases with the Non-Defaulting Buyers'
initial elections and final elections after adjustments by the above method.

- --------------
         (3) The appropriate factor is the quotient of (1) (a) the UMPA less (b)
         the election of the Non-Defaulting Buyer not on the list divided by (2)
         the sum of the two elections before the reduction.

         (4) The appropriate factor is the greater of (1) the quotient of (a)
         the UMPA less the election of the third Buyer on the list divided by
         (b) the sum of the two Buyers' elections before the reduction or (2)
         the quotient of (a) the election ratio of the third Buyer on the list
         divided by (b) the election ratio of the first Buyer on the list.

         Column 8 of the table lists the Basic Purchase Shares of the
Non-Defaulting Buyers. Column 9 expresses each Basic Purchase Share as a
proportion of the total of the NonDefaulting Buyers' Basic Purchase Shares.

         Case 1: The Non-Defaulting Buyers elect 70, 93, and 0 Wafer
Equivalents, respectively (rows 1 to 3, column 2). Since the election total (93
Wafer Equivalents; row 4, column 2) is less than 100 Wafer Equivalents, each
Non-Defaulting Buyer will take its initial election (see rows 5 to 7, column 2).

         Case 2: The Non-Defaulting Buyers elect 100, 100, and 4 Wafer
Equivalents, respectively (rows 1 to 3, column 4). Since the election total (204
Wafer Equivalents) exceeds the UMPA, some of the elections must be reduced.
Comparing columns 4 and 9 (rows 1 to 3), we see that Buyer No. 1's and Buyer No.
3's elected proportions exceed their respective Basic Purchase Shares as
proportions of the sum of the Non-Defaulting Buyers' Basic Purchase Shares.
Since that is not true for Buyer No. 4, it will take its entire election.

         Buyer No. 1's and Buyer No. 3's elections must be reduced, since their
elections sum to 200. Buyer No. 3's election is reduced first, because its
election ratio (5.556) exceeds Buyer No. 1's (1.667). Even after Buyer No. 3's
election is reduced so that its election ratio equals Buyer No. 1's, the Buyers'
aggregate elections (130 Wafer Equivalents) are still too much (not shown in the
table), so each of their elections is (further) reduced (rows 5 to 6, column 4)
until their aggregate elections are 96 Wafer Equivalents. Note that at this
point, their election ratios have been reduced to 1.231 (rows 5 to 6, column 5).
Thus, once Buyer No. 3's election ratio is made equal to Buyer No. 1's, each
Buyer's election is reduced by the same factor until the two Buyers' aggregate
elections equal 96 Wafer Equivalents.

         Case 3: The Non-Defaulting Buyers elect 100 Wafer Equivalents each.
Buyer No. 4 has the highest election ratio, followed by Buyer No. 3, then Buyer
No. 1 (rows 1 to 3, column 7). As shown in rows 5 to 7, columns 6 to 7, each
Non-Defaulting Buyer's election is reduced until their three Buyers' common
election ratio is 1.220 (rows 5 to 7, column 7). In terms of the above method,
Buyer No. 4's initial election ratio (25) is first reduced to Buyer No. 3's
(5.556). Because the election total

                                                       FUTURE PURCHASE AGREEMENT
   169
still exceeds 100 Wafer Equivalents (not shown in the table), both Buyers'
election ratios are reduced to Buyer No. 1's (1.667). Because the election total
is still too high (not shown in the table), all Non-Defaulting Buyers' election
ratios are reduced to the final value of 1.220, at which point the election
total is 100 Wafer Equivalents.

   171
         1.       DEFINITION OF CONFIDENTIAL INFORMATION

                  As used herein, "Confidential Information" shall mean (a) all

mask-works, trade and industrial secrets and improvements relating to research,
development or manufacturing activities of the Company or other parties to the
Purchase Agreement. Confidential Information shall include not only written

         2.       NON-CONFIDENTIAL INFORMATION

                  The term "Confidential Information" does not include
information which (a) becomes generally available to the public other than as
the result of a disclosure by the Receiving Party; (b) was available to the
Receiving Party on a nonconfidential basis (including, but not limited to
information developed by that party) prior to its disclosure to the Receiving
Party by the Disclosing Party; (c) becomes available to the Receiving Party on a
nonconfidential basis from a source other than the Disclosing Party provided
that such source is not bound by a confidentiality agreement with the Disclosing
Party or the Company or is not otherwise prohibited from transmitting the
information to the Receiving Party by a contractual, legal or fiduciary
obligation; or (d) is required to be disclosed by the Receiving Party pursuant
to law, governmental regulation or judicial order, provided that written notice
is given to the Disclosing Party and the Company prior to the required
disclosure.

         3.       USE OF CONFIDENTIAL INFORMATION

                  The Receiving Party shall use Confidential Information solely
for the Purpose and for no other purpose.

         4.       DISCLOSURE OF CONFIDENTIAL INFORMATION

                  Without the prior consent of the Disclosing Party, the

Information has been made available to the Receiving Party or that the Receiving
Party has inspected any Confidential Information, except to the extent the
foregoing is required to be disclosed by the Receiving Party pursuant to law,
governmental regulation or judicial order, provided that written notice is given
to the Disclosing Party and the Company prior to the required disclosure. The
fact that such information has been delivered to the Receiving Party is deemed
to be Confidential Information for the purposes of this Agreement, except to the
extent the foregoing is required to be disclosed by the Receiving Party pursuant
to law, governmental regulation or judicial order, provided that written notice
is given to the Disclosing Party and the Company prior to the required
disclosure.

   172
         5.       DESTRUCTION OR RETURN OF CONFIDENTIAL INFORMATION

                  Upon request from the Disclosing Party to the Receiving Party
(a) the Receiving Party shall (i) either destroy or return to the Disclosing
Party all Confidential Information received in tangible form, including any
copies of which the Receiving Party may have made, (ii) destroy all abstracts,
summaries thereof or references thereto in the documents of the Receiving Party,
and (iii) certify to Disclosing Party that this has been done, and (b) the

to, or in furtherance of, any of the Receiving Party's businesses or in the
business of anyone else, or for any other purpose whatsoever.

         6.       INDEMNIFICATION

                  The Receiving Party hereby agrees to indemnify, defend and
hold harmless the Disclosing Party, the other parties to the Purchase Agreement,
and the Company (each such indemnified party, an "Indemnitee") from any damages,
loss, cost or liability (including legal fees and costs of enforcing this
indemnity) arising out of or resulting from any unauthorized use or disclosure
by the Receiving Party of the Confidential Information.

         7.       REMEDIES

                  Receiving Party acknowledges that money damages would be both
incalculable and an insufficient remedy for any breach of this Agreement by a
Receiving Party, and that such breach would cause one or more Indemnitees
irreparable harm. In addition to all other remedies available to an Indemnitee
at law, in equity or under this Agreement, the Indemnitee will be entitled to
specific performance and injunctive or other equitable relief as a remedy for
any such breach, and the breaching party agrees to waive any requirement of
receiving or posting of any bond in connection with such remedy. The Receiving
Party agrees and consents to the entry of a preliminary injunction or protective
order by any court of competent jurisdiction upon a showing by an Indemnitee
that Confidential Information is being used or disclosed contrary to the
provisions of this Agreement to the detriment of the Indemnitee.

         8.       NO LICENSE

                  This Agreement does not imply any license to the Receiving
Party of Confidential Information or any of patents, copyrights, trademarks,
mask-work rights or applications therefor. All proprietary rights, including but
not limited to patent rights and trade and industrial secrets, in and to the
Confidential Information shall remain the property of its owner prior to
disclosure by the Disclosing Party to the Receiving Party.

         9.       DEGREE OF CARE, AGREEMENTS BINDING ON OFFICERS, EMPLOYEES,
                  ETC.

Information it receives from the Disclosing Party in strict confidence and with
the same degree of care that Receiving Party


                                       K-3

less than a reasonable degree of care, (b) Receiving Party's covenants and
agreements set forth in this Agreement shall be binding upon its officers,
directors, employees, representatives and agents; and (c) the Receiving Party
shall cause its officers, directors, employees, representatives and agents to
abide by the provisions of this Agreement.

         10.               WAIVERS

                  It is understood and agreed that no failure or delay by the
Disclosing Party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise thereof
preclude any or further exercise or the exercise of any right, power or
privilege hereunder.

         11.               SEVERABILITY

                  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect.

                  This Agreement shall be governed by and construed in
accordance with the laws of Delaware.

         13.               DURATION

                  This Agreement shall become effective upon execution and
delivery hereof and shall continue in full force and effect for so long as the
Disclosing Party shall exist; provided, however, that the obligation of the
Receiving Party under paragraphs 3, 4, 5, 6, 7, 8, 9, 12, 14 and 15 shall
survive indefinitely.

         14.               ENTIRE AGREEMENT; SURVIVAL; SUCCESSORS AND ASSIGNS

                  This Agreement contains the entire understanding of the
parties hereto concerning the subject matter hereof and supersedes any prior
agreement or understanding of the parties. This Agreement may not be modified
except in writing, duly signed by the party against whom enforcement is sought.
This Agreement shall inure to the benefit of and be binding upon each of the
parties hereto and their respective heirs, successors, assigns and personal
representatives.

         15.      The Company is a third-party beneficiary under this Agreement.

                           FORM OF INDEMNITY AGREEMENT

                               INDEMNITY AGREEMENT

                  This Indemnity Agreement ("Agreement") is entered into as of
______________ by [Buyer] , a ________________ corporation, as indemnifying
party hereunder ("Indemnitor"), and WaferTech LLC, a Delaware limited liability
company, as indemnified party ("Indemnitee").

                                    RECITALS

         A.       Indemnitor and Indemnitee, among others, are parties, to that
certain Purchase Agreement, dated ___________________ (the "Purchase
Agreement").

         B.       Capitalized terms not otherwise defined in this Agreement have
the meanings given them in the Purchase Agreement.

         C.       Pursuant to the Purchase Agreement, Indemnitee will sell and
the other parties to that agreement will buy semiconductor wafers produced by
Indemnitee at the Foundry.

         D.       Under Section 5.10 of the Purchase Agreement, if Indemnitor
orders Products from Indemnitee that require the grant of non-exclusive
Intellectual Property Rights relating to the Products' manufacture or sale,
Indemnitor must, as a condition to Indemnitee's manufacturing and delivering
such Products, either grant the necessary Intellectual Property Rights to
Indemnitee or enter into this Agreement. Indemnitor wishes to order Products
under the Purchase Agreement from Indemnitee and declines to obtain and grant to
it non-exclusive rights in Intellectual Property Rights relating to such
Products. Accordingly, Indemnitor desires to enter into this Agreement.

         E.       The Product/Products covered by this Agreement is/are as
follows:

                  NOW, THEREFORE, in consideration of the premises and covenants
herein and other good and valuable consideration, the receipt and sufficiency of
which are acknowledged, the parties hereto agree as follows:

         1.       Except as expressly otherwise provided in Section 11.1 of the
Purchase Agreement, Indemnitor shall indemnify, defend, and hold harmless
Indemnitee, TSMC, and their respective Affiliates, employees, officers,
directors, shareholders, partners, members, and agents (collectively,

"Indemnified Persons") against or from any Claim of infringement or
misappropriation of a third party's Intellectual Property Rights arising out of,
related to, or connected with the Product or Products described in Recital E
above.

         2.       This Agreement shall be governed by Section 10.2(a) of the
Purchase Agreement.

         3.       Any payment hereunder shall be made in U.S. dollars. Any
amount due and payable to an Indemnified Person under paragraph 1 and not paid
within 30 days of written demand for payment shall accrue interest compounded
annually at a rate equal to the lesser of (a) the sum of (i) the prime or
reference rate for commercial borrowing announced by the Bank of America
N.T.&S.A. from time to time and (ii) 5% or (b) the maximum rate of interest
permitted by applicable law.

         4.       Indemnitor's obligation to Indemnitee under paragraph 1 shall
be conditioned upon:

                  a.       Indemnitee's giving Indemnitor prompt notice in
writing of any Claims subject to the indemnity of paragraph 1 and of which

         5.       The indemnity of paragraph 1 shall be interpreted and

         10.      No waiver of any provision hereof shall be effective unless
and until made in writing and signed by the party to be charged. No waiver,
forbearance or failure by any party hereto of its right to enforce any provision
of this Agreement shall constitute a waiver or estoppel of such party's right to
enforce any other provision of this Agreement or a continuing waiver by such
party of compliance with any provision.

         11.      In the event of any litigation, arbitration, judicial
reference or other proceeding involving the parties hereto to enforce any
provision hereof, to enforce any remedy available upon default hereunder, or
seeking a declaration of the rights of a party hereunder, the prevailing party
shall be entitled to recover from the other such attorneys' fees and costs as
may be reasonably incurred, including the cost of reasonable investigation,
preparation and professional or expert consultation incurred by reason of such
litigation, arbitration, judicial reference or other proceeding. Notwithstanding
the foregoing, (a) in an arbitration proceeding the award of attorneys' fees
shall be governed by the provisions of Section 17.6 in the Purchase Agreement;
and (b) in a mediation under Section 17.2 of the Purchase Agreement, each Party
shall pay its own attorneys' fees and expenses in accordance with said Section
17.2.

         12.      With the exception of Section 17.7, the dispute resolution and
arbitration provisions of Article 17 of the Purchase Agreement are incorporated
by reference herein; provided that the term "Parties" as used in said Article 17
refer to Indemnitor and Indemnitee hereunder.

         13.      This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors, transferees, and assigns.

         14.      Each party hereto irrevocably consents to the jurisdiction of
the state and Federal courts located in San Jose, California; agrees, subject to
the provisions of Article 17 of the Purchase Agreement, that any action, suit or
proceeding by or between the parties may be brought in any such court sitting in
San Jose, California; and waives any objection which the party may now or
hereafter have concerning jurisdiction and venue, whether based on
considerations of personal jurisdiction, forum non conveniens or on any other
ground. Each party hereby irrevocably designates, appoints and empowers the
Secretary of State of California to receive for and on behalf of such party
service of process in the State of California and further irrevocably consents
to the service of process outside of the territorial jurisdiction of said courts
by mailing copies thereof by registered or certified United States mail, postage
prepaid, to such party's last known address as established in accordance with
the Purchase Agreement with the same effect as if the Party were a resident of
the State of California and had been lawfully served in such state. Any process
served on the California Secretary of State in accordance with the preceding
sentence shall also be noticed to the party's last known address established in
accordance with the Purchase Agreement. Nothing in this Agreement shall affect
the right to service of process in any other manner permitted by law. Each party
further agrees that final judgment against it in any such action or proceeding
shall be conclusive and may be enforced in any other jurisdiction within or
outside the State of California by suit on the judgment, a certified or
exemplified copy of which shall be conclusive evidence of the fact and the
amount of such judgment.
