                              ANALOG DEVICES, INC.

              Senior Management Change in Control Severance Policy
              ----------------------------------------------------

                          (Effective December 13, 1988)

               (As Amended on June 13, 1989 and December 9, 1993)

1.       Purpose
         -------

         The purpose of this Senior Management Change in Control Severance
Policy is to diminish the distraction of covered employees (as defined below) in
the event of a threatened or pending Change in Control (as defined below) and to
provide financial assistance to any covered employee whose employment with
Analog Devices, Inc. or any of its subsidiaries is terminated under certain
circumstances following such a Change in Control. For purposes of this Policy, a
covered employee shall be any employee of the Company with a labor grade of 15
or above (as of the time of termination) who is not covered under any severance
pay agreement (other than a stock option or restricted stock agreement) that
provides special cash benefits following such a Change in Control. Unless the
context otherwise requires, the "Company" means Analog Devices, Inc. and its
subsidiaries (other than portfolio companies of AD Enterprises).

2.       Eligibility for Severance Benefits
         ----------------------------------

         (a) A covered employee shall qualify for severance benefits under this
Policy if following a Change in Control (as defined below) the employee is
terminated from employment by the Company other than for Cause or Disability (as
such terms are defined below) or by the employee for Good Reason (as defined
below).

         (b) For purposes of this Policy, termination by the Company of
employment for Cause shall mean termination (a) upon the willful and continuing
failure by the employee to substantially perform his or her duties with the
Company, provided that a written demand for substantial performance has been
delivered to the employee by the Company specifically identifying the manner in
which the Company believes that such employee has not substantially performed
his or her duties and such employee shall not have cured such failure within 30
days after such demand or (b) by reason of the employee's willful engagement in
conduct which is demonstrably and materially injurious to the Company. For
purposes of this Policy, no act or failure to act on the part of an employee
shall be deemed "willful" unless done or admitted to be done by the employee not
in good faith and without reasonable belief that his or her action or omission
was in the best interest of the Company.

         (c) For purposes of this Policy, Disability shall mean that as a result
of incapacity due to physical or mental illness, the employee shall have been
absent from the full-time performance of his or her duties with the Company for
six consecutive months and, within 30 days after written notice of termination
is given to the employee, the employee shall not have returned to the full-time
performance of his or her duties.
<PAGE>   2
         (d) For purposes of this Policy, Good Reason shall mean, without the
employee's written consent, the occurrence after a Change in Control of the
Company of any of the following circumstances:

             (A) any significant diminution in the employee's position, duties,
responsibilities, power, title or office as in effect immediately prior to a
Change in Control;

             (B) any reduction in the employee's annual base salary as in effect
on January 1, 1989 or as the same may be increased from time to time;

             (C) the failure of the Company to continue in effect any material
compensation or benefit plan in which the employee participates immediately
prior to the Change in Control, unless an equitable arrangement (embodied in an
ongoing substitute or alternative plan) has been made with respect to such plan,
or the failure by the Company to continue his or her participation therein (or
in such substitute or alternative plan) on a basis not materially less
favorable, both in terms of the amount of benefits provided and the level of his
or her participation relative to other participants, as existed at the time of
the Change in Control;

             (D) the failure by the Company to continue to provide the employee
with benefits substantially similar to those enjoyed by him or her under any of
the Company's life insurance, medical, health and accident, or disability plans
in which he or she was participating at the time of the Change in Control, the
taking of any action by the Company which would directly or indirectly
materially reduce any of such benefits, or the failure by the Company to provide
him or her with the number of paid vacation days to which he or she is entitled
on the basis of years of service with the Company in accordance with the
Company's normal vacation policy in effect at the time of the Change in Control;
or

             (E) any requirement by the Company or of any person in control of
the Company that the location at which the employee performs his or her
principal duties for the Company be changed to a new location outside a radius
of 50 miles from his or her principal residence at the time of the Change in
Control.

3.       Change in Control

         For purposes of this Policy, a Change in Control shall occur or be
deemed to have occurred only if any of the following events occur: (i) any
"person," as such term is used in Sections 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), (other than the Company,
any trustee or other fiduciary holding securities under an employee benefit plan
of the Company, or any corporation owned directly or indirectly by the
stockholders of the Company in substantially the same proportion as their
ownership of stock of the Company) is or becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of
securities of the Company representing 50% or more of the combined voting power
of the Company's then outstanding securities; (ii) individuals who, as of the
effective date hereof, constitute the Board of Directors of the Company (as of
the date hereof, the "Incumbent Board") cease for any reason to constitute at
least a majority of the Board, provided that any person becoming a director
subsequent to the date hereof whose election, or nomination for election by the
Company's stockholders, was approved by a vote of at

                                       2
<PAGE>   3
least a majority of the directors then comprising the Incumbent Board (other
than an election or nomination of an individual whose initial assumption of
office is in connection with an actual or threatened election contest relating
to the election of the directors of the Company, as such terms are used in Rule
14a-11 of Regulation 14A under the Exchange Act) shall be, for purposes of this
Agreement, considered as though such person were a member of the Incumbent
Board; (iii) the stockholders of the Company approve a merger or consolidation
of the Company with any other corporation, other than (A) a merger or
consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than 80% of the combined voting power of the voting
securities of the Company or such surviving entity outstanding immediately after
such merger or consolidation or (B) a merger or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no
"person" (as hereinabove defined) acquires more than 30% of the combined voting
power of the Company's then outstanding securities; or (iv) the stockholders of
the Company approve a plan of complete liquidation of the Company or an
agreement for the sale or disposition by the Company of all or substantially all
of the Company's assets."

4.       Computation of Severance Benefit
         --------------------------------

         If a covered employee's employment by the Company shall be terminated
by the Company other than for Cause or Disability during the 18-month period
following a Change in Control or a covered employee terminates employment with
the Company for Good Reason during the 18-month period following a Change in
Control, then such employee shall be entitled to receive, promptly upon the
termination of his or her employment, a lump-sum severance payment equal to the
base salary otherwise payable to such employee for the following number of
weeks'employment with the Company, plus an amount equal to the aggregate cash
bonuses paid or awarded by the Company to such employee in respect of the four
fiscal quarters preceding such termination of employment:

<TABLE>
<CAPTION>
Period of Employment                 Number of Weeks
Prior to Termination                 of Base Salary

<S>                                  <C>
Less than 10 years                   52 weeks

10 years or more                     62 weeks, plus 4 weeks for each full year
                                     of employment over 10 years, up to a
                                     maximum of 104 weeks in the aggregate
</TABLE>

         Subject to the provisions of Section 6(b), this Policy establishes in
each covered employee, following a Change in Control, a contractual right to the
benefits to which he or she is entitled under this Policy, and such rights shall
be enforceable by each covered employee against the Company following a Change
in Control.

5.       Certain Reduction of Payments by the Company
         --------------------------------------------

         (a) Anything in this Policy to the contrary notwithstanding, in the
event it shall be determined that any payment or distribution by the Company to
or for the benefit of the

                                       3
<PAGE>   4
employee (whether paid or payable or distributed or distributable pursuant to
the terms of this Policy or otherwise) (a "Payment") would be nondeductible by
the Company for federal income tax purposes because of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code"), then the aggregate
present value of amounts payable or distributable to or for the benefit of such
employee pursuant to this Policy (such payments or distributions pursuant to
this Policy are hereinafter referred to as "Policy Payments") shall be reduced
to the Reduced Amount. The "Reduced Amount" shall be an amount expressed in
present value which maximizes the aggregate present value of Policy Payments
without causing any Payment to be nondeductible by the Company because of
Section 280G of the Code. For purposes of this Section 5, present value shall be
determined in accordance with Section 280G(d)(4) of the Code.

         (b) All determinations required to be made under this Section 5 shall
be made by the Company's independent public accountants (the "Accounting Firm")
which shall provide detailed supporting calculations both to the Company and the
employee. Any such determination by the Accounting Firm shall be binding upon
the Company and the employee.

         (c) As a result of the uncertainty in the application of Section 280G
of the Code at the time of the initial determination by the Accounting Firm
hereunder it is possible that Policy Payments will have been made by the Company
which should not have been made ("Overpayment") or that additional Policy
Payments which will not have been made by the Company could have been made
("Underpayment"), in each case, consistent with the calculations required to be
made hereunder. In the event that the Accounting Firm, based upon the assertion
of a deficiency by the Internal Revenue Service against the employee which the
Accounting Firm believes has a high probability of success determines that an
Overpayment has been made, any such Overpayment paid or distributed by the
Company to or for the benefit of the employee shall be treated for all purposes
as a loan ab initio to the employee which the employee shall repay to the
Company together with interest at the applicable federal rate provided for in
Section 7872(f)(2) of the Code; provided, however, that no such loan shall be
deemed to have been made and no amount shall be payable by the employee to the
Company if and to the extent such deemed loan and payment would not either
reduce the amount on which the employee is subject to tax under Section 1 and
Section 4999 of the Code or generate a refund of such taxes. In the event that
the Accounting Firm, based upon controlling precedent or other substantial
authority, determines that an Underpayment has occurred, any such Underpayment
shall be promptly paid by the Company to or for the benefit of the employee
together with interest at the applicable federal rate provided for in Section
7872(f)(2) of the Code.

6.       Amendment and Termination
         -------------------------

         (a) This Policy shall be effective until December 31, 1994 and shall
continue in effect thereafter unless the Board of Directors of the Company shall
vote to terminate or modify this Policy, provided, however, that if a Change in
Control shall have occurred prior to December 31, 1994 (or such later date that
this Policy is in effect because no action has been taken by the Board of
Directors to terminate this Policy), this Policy shall remain in effect for a
period of not less than 18 months after the date of such Change of Control and
all obligations of the Company arising under this Policy as a result of any
termination during such 18-month period shall survive until such obligations are
fully performed.

                                       4
<PAGE>   5
         (b) Notwithstanding the foregoing, this Policy and the benefits
described herein may be amended or terminated by the Board of Directors of the
Company at any time; provided, however, that following a Change in Control this
Policy may not be terminated or amended in any manner materially adverse to then
covered employees without the written consent of a majority of the covered
employees actively employed by the Company and covered by this Policy both
immediately prior to the Change in Control and at the date of such amendment.

7.       No Mitigation
         -------------

         An employee shall not be required to mitigate the amount of any payment
provided for in this Policy by seeking other employment or otherwise and shall
not be required to offset against such payment any payments he or she may
receive from further employment.

8.       No Fiduciary or Employment Relationship
         ---------------------------------------

         Nothing contained in this Policy and no action taken pursuant to the
provisions of this Policy shall create or be construed to create a trust of any
kind or fiduciary relationship or contract for employment between the Company
and any employee, and nothing in this Policy shall affect the right of the
Company to terminate the employment of any employee for any reason whatsoever.

9.       Notice
         ------

         For the purpose of this Policy, notices and all other communications
provided for in the Policy shall be in writing and shall be deemed to have been
duly given when delivered in person or mailed by United States registered mail,
return receipt requested, postage prepaid.

10.      Withholding
         -----------

         Any payment provided for hereunder shall be paid net of any applicable
withholding required under foreign, federal, state or local law.

11.      Governing Law
         -------------

         All questions pertaining to the construction, regulation, and validity
and effect of the provisions of this Policy shall be determined in accordance
with the laws of the Commonwealth of Massachusetts without regard for the
conflict of law principles thereof.

12.      Conflict with Surplus (Reduction in Work Force) Policy
         ------------------------------------------------------

         Any payments made to a covered employee under this Policy shall be in
lieu of, and not in addition to, any payments to such employee under the
Company's Surplus (Reduction in Work Force) Policy.

                       ASSURED SUPPLY AND DEMAND AGREEMENT

--------------------------------------------------------------------------------

<PAGE>   2

                       ASSURED SUPPLY AND DEMAND AGREEMENT

THIS AGREEMENT is made the 1st day of October 1999 by and between :-

(1)      CHARTERED SEMICONDUCTOR MANUFACTURING LTD, a company incorporated in
         Singapore and having its place of business at 60 Woodlands Industrial
         Park D, Street 2, Singapore 738406 ("CSM"); and

(2)      ANALOG DEVICES, INC. a company incorporated in Delaware and having its
         place of business at One Technology Way, Norwood, MA 02062, USA
         ("ADI").

WHEREAS

(A)      CSM and ADBV, an affiliate of ADI, had entered into a Deposit Agreement
         dated 30 January 1996 (the "Deposit Agreement") for the purpose of ADBV
         depositing certain funds with CSM and for CSM to make available to ADBV
         certain wafer manufacturing capacity. ADBV subsequently assigned its
         rights and obligations under the Deposit Agreement to ADI.

(B)      To strengthen the relationship between CSM and ADI and to meet the
         changing business needs of both Parties, CSM and ADI have decided to
         enter into this Assured Supply and Demand Agreement to supersede the
         Deposit Agreement to effect new terms and conditions under which the
         said deposit may be credited back to ADI.

NOW THEREFORE, in consideration of the foregoing and the mutual covenants
contained herein, the Parties agree as follows:-

1.       DEPOSIT AGREEMENT SUPERSEDED

         With effect from July 1, 1999 ("the Effective Date"), all terms and
         conditions of the Deposit Agreement shall be superseded by the terms
         and conditions of this Agreement, and shall cease to have any force or
         effect.

2.       THE DEPOSIT

2.1      The Parties acknowledge that ADI has deposited with CSM the sum of
         US$20,000,000 (the "Deposit") for the purposes of securing wafer
         manufacturing capacity at CSM's facilities.

2.2      With effect from the Effective Date, the Parties agree that CSM will
         refund the Deposit to ADI on the terms and conditions set out as
         follows. Partial refunds shall occur on a per wafer basis as outlined
         in Table B of ANNEX A and on a per product basis as outlined in TABLE A
         of Annex A. Product based refunds shall occur upon successful
         completion of Tapeout, Lot Acceptance or Qualification, as defined
         below and as indicated in TABLE A of Annex A. Wafer refunds per Table B
         of Annex A shall include wafers purchased by ADI, its affiliates and
         others of ADI products. If CSM is unable to accept an order for

                              CSM/ADI CONFIDENTIAL                             2

<PAGE>   3

   Confidential Materials omitted and filed separately with the Securities and
                Exchange Commission. Asterisks denote omissions.

2.3      wafers within the CSM commitment described in this Agreement, ADI shall
         be entitled to that same refund amount per wafer for any orders not
         accepted by CSM. Refunds shall be calculated at the end of each
         calendar quarter and shall be credited or paid to ADI within 30 days
         after the close of the quarter.

2.4      "Tapeout" shall be deemed to have occurred when ADI provides to CSM a
         full GDS database of a given product and CSM has communicated in
         writing to ADI that there has been no design rule violation or has
         agreed to accept the design and layout "as is." Acceptance of a
         purchase order by CSM from ADI for more than [**] wafers of a product
         shall constitute written "as is" design acceptance, unless mutually
         agreed in writing.

2.5      "Lot Acceptance" by ADI shall be defined as the successful fabrication
         of 4 production lots including 1 prototype or skew lot and 3
         qualification lots, which pass all relevant CSM WAT criteria.

2.6      "Qualification" by ADI shall be defined as the attainment of
         competitive yield and the successful completion of standard Reliability
         screens as used by ADI in the qualification of similar products,
         according to ADI specification ADI-0012.

2.7      If ADI successfully qualifies products as described in Table A of Annex
         A in accordance with the mutually agreed qualification plan in ANNEX C,
         ADI will be entitled to portions of the Deposit in accordance with
         Annex A. Any part of the Deposit that is not refunded or due to be
         refunded to ADI pursuant to Annex A on or before 30 June 2004, will not
         be refunded thereafter. However, i) if ADI shall Tapeout one or more
         products, proven to meet similar Lot Acceptance and Qualification
         criteria at another vendor, on each of three or more of the
         technologies listed in Table A of Annex A and CSM does not attain Lot
         Acceptance and Qualification by 1 January 2002, on two or more of the
         technologies listed in Table A of Annex A, or ii) CSM shall fail to
         make industry-compatible versions of three or more of the technologies
         listed in Table A of Annex A available to ADI for production use by 1
         January 2002, then any remaining deposit on 29 June 2004 shall be then
         refunded to ADI. For this purpose, an industry compatible process is
         one which can accept and qualify the same layout as accepted and
         qualified at a competitor wafer fab, after only minor revisions which
         do not affect die size.

2.8      ADI may introduce its design customers and/or licensees to use CSM's
         manufacturing facilities. If CSM agrees to provide manufacturing
         services to any such third party, wafers manufactured based on an ADI
         design pursuant to such an arrangement shall entitle ADI to the same
         wafer credits indicated in Table B of Annex A. Wafers manufactured for
         ADI under other agreements between CSM and ADI or its subsidiaries
         shall entitle ADI to the same wafer credits indicated in Table B.

                              CSM/ADI CONFIDENTIAL                             3

<PAGE>   4

2.8      All wafers shall be manufactured and supplied in accordance with CSM's
         procedures and relevant ADI and CSM specifications, including the
         existing ADI/CSM procurement spec, as to the current revision or as
         amended by mutual agreement. Copies of CSM's procedures shall be
         available upon written request by ADI.

2.9      ADI acknowledges that some of the process technologies referred to in
         Annex A may be run in either or both of CSM's joint venture fabs
         operated by Silicon Manufacturing Partners Pte Ltd ("SMP") and
         Chartered Silicon Partners Pte Ltd ("CSP"). In the event that CSM needs
         to supply ADI with any wafers out of SMP and/or CSP, ADI agrees to
         allow CSM to assign the relevant portions of this Agreement to SMP or
         CSP, as the case may be, or to enter into a separate agreement with SMP
         or CSP on similar terms as the terms of this Agreement. All 8" wafers
         purchased by ADI, its subsidiaries and assignees from CSM and its
         affiliates, regardless of the actual process, fabrication source, or
         fabrication site, shall be eligible for credit under the terms of this
         Agreement.

3.       ADI'S LOADING COMMITMENT

3.1      ADI agrees to place with CSM purchase orders of such quantity of 8-inch
         wafers as forecasted for delivery during each calendar quarter of the
         term of this Agreement.

3.2      While there are no liquidated damages associated with forecasts, both
         Parties recognize the difficulty in CSM factories accommodating sharp
         forecast changes or changes from forecast. Also, both Parties recognize
         that a certain level of capacity must be committed by CSM to ADI to
         accommodate ADI's revenue needs and to enable ADI to earn back the
         deposit as set forth in Annex A. For these reasons, the Parties have
         agreed on certain forecast guidelines below.

3.3      Forecast Timing. Forecasts refer to wafer purchase projections beyond
         the normal lead-time published by CSM and agreed by ADI. Nominally, the
         order lead-time is otherwise assumed to be 3 months for the purpose of
         such forecasts. Forecasts shall refer to wafer delivery quantities and
         dates and shall be non-binding. CSM shall acknowledge each forecast in
         writing within 10 business days, either (i) accepting such forecast,
         even though aspects may exceed the forecast quantity or variation
         guidelines noted in Section 3.8, or (ii) identifying those aspects
         which exceed guidelines and CSM's ability to sustain as their Base
         Loading Commitment. Any forecast accepted by CSM in writing within 10
         business days shall become the new Base Loading Commitment.

3.4      All wafer commitments within the agreed lead-time are made via ADI
         Purchase Orders as acknowledged and accepted by CSM. Purchase Orders
         accepted by CSM are considered binding agreements for CSM to deliver
         and ADI to accept the stated quantity and type of wafers, in accordance
         with all relevant CSM procedures and all agreed ADI and CSM
         specifications, including the existing ADI/CSM procurement spec, as to
         the current revision or as amended by mutual agreement. Purchase Orders
         are time sensitive documents and must be acknowledged and accepted in
         writing by CSM within 10 business days or they are considered null and
         void. Wafer orders which are not delivered within the agreed delivery
         lead-time, plus a grace period of no more than 30 days, upon placement
         and acceptance of the Purchase Order, are subject to cancellation by
         ADI on 2

                              CSM/ADI CONFIDENTIAL                             4

         business days notice. There is no penalty for cancellation due to late
         delivery as described in this section. To the extent that the terms of
         Purchase Orders and other documents are inconsistent with the terms of
         this Agreement, this Agreement shall take precedence, unless CSM and
         ADI specifically agree to amended terms in a separate agreement. The
         terms of a quotation and purchase order shall not constitute such
         amendment.

3.5      Quarterly Forecast. ADI's monthly wafer delivery requirements forecast
         for those products to be manufactured over the next 18 months will be
         provided quarterly on an agreed timetable (the "Quarterly Forecast").
         The first such forecast is set out in ANNEX B (the "Original
         Forecast"). The first 3 months of each Quarterly Forecast shall be
         backed by Purchase Orders for those 3 months as described above.
         Subject to Section 3.8 hereof, the Original Forecast shall be updated
         by ADI at the end of every calendar quarter. Future Quarterly Forecasts
         shall cover the period from 10 to 18 months from the forecast date,
         indicating total wafer demand by process. The period from 4 to 9 months
         shall be covered by the monthly forecast as outlined below.

3.6      Monthly Forecast. On a monthly basis, ADI shall provide CSM with a
         6-month rolling forecast, by product and process, of its monthly volume
         requirements for wafers covering the period from 4 to 9 months from the
         forecast date. ADI will update the 6-month forecast on or before the
         26th of each month (the "Monthly Forecast"). ADI shall indicate on the
         forecast those products for which ADI requests CSM to obtain circuit
         probe capacity and commit to execute circuit probing within the order
         lead time.

3.7      Base Loading Commitment. For the purposes of establishing CSM's
         capacity commitment to ADI, the concept of Base Loading Commitment is
         introduced and is defined as the first Monthly Forecast, (as defined in
         Section 3.6) of each quarter as accepted by CSM in writing plus the
         corresponding Quarterly Forecast (as defined in section 3.5) of the
         same date as submitted by ADI as adjusted for flexibility in accordance
         with Section 3.8.

              and Exchange Commission. Asterisks denote omissions.

3.8      Loading Commitment Flexibility.

3.8.1    ADI's loadings per month shall not vary from one third of the relevant
         quarter's Base Loading Commitment by more than [**].

3.8.2    On a quarterly basis, ADI may modify the Base Loading Commitment as
         follows:

            Period                           Pre-approved Modification
(Forecast Quarter = Quarter 0;    (Percentage of the same month forecast made in
     current month = month 0           the previous Base Loading Commitment)
     e.g. Mar 2000)
Quarter 1 (e.g. Apr - Jun 2000)    +/- 0% as covered by Accepted Purchase Orders
Quarter 2 (e.g. Jul - Sep 2000)           The lesser of + / - [**] wafers
Quarter 3 (e.g. Oct - Dec 2000)           The lesser of + / - [**] wafers
Quarter 4 (e.g. Jan - Mar 2001)           The lesser of + / - [**] wafers
Quarter 5 (e.g. Apr - Jun 2001)           The lesser of + / - [**] wafers
Quarter 6 (e.g. Jul - Sep 2001)           The lesser of + / - [**] wafers

3.8.3    Notwithstanding the foregoing, should any ADI forecast exceed the
         pre-approved modification for any calendar quarter, CSM shall have the
         right to accept or reject that revised forecast. CSM shall have 14
         business days to either accept or reject the modified forecast in
         writing. If CSM accepts the modified forecast, then it shall become the
         new Base Loading Commitment.

         A table to demonstrate how the above flexibility model operates with
         respect to the Original Forecast is set out in ANNEX B.

4.       CSM'S SUPPLY COMMITMENT

4.1      In consideration of the retention of the Deposit, CSM hereby agrees to
         supply wafers as per the Base Loading Commitment. Unless otherwise
         agreed to by CSM in writing, CSM shall not be contractually obligated
         to provide more than [**] wafers under this Agreement in a given month
         through December 31, 2000. Thereafter, and unless otherwise agreed to
         by CSM in writing, CSM shall not be contractually obligated to provide
         more am [**]wafers per month or [**] wafers per month per [**]
         outstanding Deposit balance, whichever is greater.

4.2      CSM's Supply Commitment set out in Section 4.1 above shall be limited
         to the mix of technologies set out in the Original Forecast in Annex B
         or in subsequent forecasts as accepted by CSM and shall continue for so
         long as any portion of the Deposit remains outstanding, unless the
         Agreement is terminated under Section 6.

4.3      CSM's Supply Commitment under this Agreement shall be considered
         separate from and in addition to CSM's Supply Commitment under other
         agreements between the Parties.

5.       EFFECTIVE DATE

5.1      The effective date of this Agreement shall be July 1st, 1999.

6.       TERMINATION DATE

6.1      Unless terminated earlier by the Agreement of the parties or on the
         complete refund of the Deposit, this Agreement shall terminate
         automatically on June 30, 2004. Any remaining amount of the Deposit
         unrefunded as of June 30, 2004 and not pending reimbursement via
         mechanisms in Annex A shall be retained by CSM with no recourse for
         recovery by ADI, as provided in Section 2.6.

7.       PRICING AND PAYMENT TERMS

7.1      The purchase price of wafers charged to ADI shall be in accordance with
         the terms of the relevant CSM price quotation agreed to by the Parties
         from time to time for the relevant lots of wafers purchased. CSM
         commits to provide wafers at market competitive prices.

7.2      Unless otherwise set out in the applicable Agreed Price Quotation,
         payment for wafers ordered shall be made by ADI in United States
         dollars within 45 days from the date of the applicable invoices issued
         by CSM. ADI shall make payment by telegraphic transfer to an account
         nominated by CSM. Any late payment for Wafers shall be subject to
         interest charges of 1.5% per month.

7.3      All invoices issued by CSM shall identify the wafers and the relevant
         ADI Purchase Order number, Product part number, Purchase Order line and
         release number, description of items, and quantity of items shipped.
         Unless otherwise agreed by ADI and CSM in writing, invoices may be
         dated no earlier than the relevant date of delivery.

7.4      In the event of any dispute over the amount invoiced, ADI shall first
         make payment of the undisputed portion in accordance with Section 7.2
         pending resolution of the dispute between the Parties.

7.5      ADI shall pay, in addition to the prices of wafers stipulated herein,
         the amount of any freight, insurance, handling and other duties levied
         on the shipment of wafers to ADI. ADI shall also pay for all sales,
         use, excise or other similar taxes levied on the purchase of wafers by
         ADI hereunder.

7.6      CSM may, in its discretion upon written notice to ADI, change the terms
         of payment to cash, cash-on-delivery or letter of credit or place ADI
         on credit hold in the event that ADI is late in its payments under this
         Agreement.

8.       PROCEDURE FOR RETURN OF WAFERS

8.1      The return of wafers shall be in accordance with the current CSM
         specification QX-038. The time limit for the return of wafers due to
         low sort yield is 60 days from the delivery date of such wafers, and
         the time limit for the return of Wafers due to reliability failures is
         1 year from the delivery date of such wafers.

8.2      CSM shall have no liability and shall not be obliged to accept the
         return of wafers after the relevant period of 60 days or 1 year, as the
         case may be. In addition, CSM shall be under no liability for defects
         in the wafers caused by static discharge, abnormal working conditions,
         fair wear and tear, accident, willful damage, abuse, misuse, neglect,
         improper installation, repair or alteration by persons other than CSM,
         improper testing and/or improper storage and/or improper handling or
         use contrary to any instructions issued by CSM which are in keeping
         with generally accepted industry practices. Further, CSM shall be under
         no liability for any parts or materials it has not manufactured.

8.3      CSM shall have the discretion to decide whether or not to conduct
         failure analysis on the wafers returned by ADI, and if such failure
         analysis is conducted, CSM will, at ADI's request, provide ADI with
         copies of the results of such analysis. If it is mutually agreed that
         the defects are due to causes other than the causes specified in
         Section 8.2, then ADI may at its option elect for either a full credit
         for the purchase price paid for such wafers, or CSM's replacement of
         the defective wafers returned to CSM. If ADI elects for the replacement
         of defective wafers, the manufacture of such wafers shall have high
         priority on CSM's production schedule, at no further cost to ADI.

8.4      THE FOREGOING STATES CSMS ENTIRE LIABILITY, WHETHER IN CONTRACT OR IN
         TORT FOR DEFECTS IN WAFERS. THE EXPRESS TERMS OF THIS AGREEMENT ARE IN
         LIEU OF ALL WARRANTIES, CONDITIONS, TERMS, UNDERTAKINGS, AND
         OBLIGATIONS IMPLIED BY STATUTE, COMMON LAW, CUSTOM, TRADE USAGE, COURSE
         OF DEALING OR OTHERWISE, ALL OF WHICH ARE HEREBY EXPRESSLY EXCLUDED TO
         THE FULLEST EXTENT PERMITTED BY LAW AND CSM SPECIFICALLY DISCLAIMS ANY
         WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

9.       PRODUCTION HALTS

9.1      ADI may at any time request CSM to halt the manufacture of wafers still
         in-process and CSM shall effect production stoppage, within 2 business
         days at a point in the process that is consistent with subsequent
         successful completion. The manufacture of Wafers shall remain on hold
         pending written directions from ADI. If such hold extends beyond 90
         days, CSM will deem the hold to be a cancellation of the order and ADI
         will be invoiced in accordance with Section 9.2.

<PAGE>   9

9.2      If ADI places an order on hold beyond 90 days or decides to cancel an
         order for reasons other than late delivery, ADI shall pay to CSM a
         Cancellation Fee based on the formula below:

                   CF = [(CS DIVIDED BY TS) X (P - R)] + R + T

         where

         'CF'     means the cancellation fee payable by Customer.

         'CS'     means the number of completed manufacturing steps as at the
         date of cancellation.

         'TS'     means the total number of manufacturing steps required to
         produce the Wafers had there not been any cancellation.

         'P'      refers to the purchase price of the Wafer as set out in the
         applicable Agreed Price Quotation.

         'R'      refers to the raw wafer cost incurred by CSM.

         'T'      refers to any applicable sales, use, excise or other similar
         taxes levied on or otherwise payable in connection with the
         Cancellation Fee.

9.3      CSM shall, if commercially feasible, re-start the manufacture of wafers
         within a reasonable time after receipt of ADI's written request,
         subject to ADI's agreement to bear all expenses incurred by CSM in
         production stoppage and re-start. CSM will make no commitments of
         yield, reliability and conformance with the Acceptance Criteria in
         respect of wafers stopped in-process (a) more than one time regardless
         of the number of days of stoppage, or (b) if the stoppage lasts for
         more than 90 days.

10.      DELIVERY

10.1     CSM shall use its commercially reasonable efforts to deliver the exact
         quantity of wafers stipulated in the relevant ADI Purchase Order.
         However if for each Purchase Order the aggregate quantity of wafers
         delivered by CSM is either within plus or minus 5% of the quantity
         ordered or within plus or minus 1 wafer, whichever is greater, such
         quantity shall constitute compliance with ADI Purchase Order.

10.2     Unless otherwise agreed by the Parties, Wafers shall be delivered
         Ex-Works (CSM's factory in Singapore) (INCOTERMS 1990). CSM shall use
         its commercially reasonable efforts to deliver within the scheduled
         delivery date. However if for each purchase order, wafers are delivered
         within plus or minus 7 days of the scheduled delivery date, such
         delivery shall constitute compliance with ADI Purchase Order. CSM shall
         promptly give ADI written notice of any prospective failure to deliver
         within the scheduled deliver date.

                              CSM/ADI CONFIDENTIAL                             9

    Confidential Materials omitted and filed separately with the Securities
              and Exchange Commission. Asterisks denote omissions.

10.3     All quantities of wafers shall be delivered in CSM standard containers
         with proper labels identifying the specific product and lot number and
         shall be accompanied by a packing list specifying the relevant purchase
         order number, wafer lot number, Wafer quantity and number of good
         un-inked die (if wafers have been sorted) and agreed upon processing
         documentation.

10.4     If ADI fails to take delivery of any quantity of wafers or fails to
         give adequate delivery instructions (otherwise than by reason of any
         cause beyond ADI's reasonable control or by reason of CSM's fault),
         then without prejudice to any other right or remedy available to CSM,
         CSM may at its option, store such wafers until actual delivery and
         charge ADI for reasonable costs (including insurance) of storage.

11.      FORCE MAJEURE

11.1     Each Party's obligations under this Agreement shall be suspended upon
         the occurrence of a force majeure event such as act of God, flood,
         earthquake, fire, explosion, act of government, war, civil commotion,
         insurrection, embargo, riots, lockouts, labour disputes affecting such
         Party, for such period as such force majeure event may subsist. Upon
         the occurrence of a force majeure event, the affected Party shall
         notify the other Party in writing of the same and shall by subsequent
         written notice after the cessation of such force majeure event inform
         the other Party of the date on which that Party's obligation under this
         Agreement shall be reinstated.

11.2     Notwithstanding anything in this Section 11, upon the occurrence of a
         force majeure event affecting either Party, if such force majeure event
         continues for a period exceeding 6 consecutive months without a
         prospect of a cure of such event, the other Party shall have the
         option, in its sole discretion, to terminate this Agreement. Such
         termination shall take effect immediately upon the written notice to
         that effect from the other Party to the Party affected by the force
         majeure event.

11.3     If a force majeure event prevents CSM from supplying wafers to ADI, the
         termination date set forth in Section 6 shall be automatically extended
         by the duration of the force majeure event.

12.      USE RESTRICTION AND LIMITATION OF LIABILITY

12.1     ADI accepts all responsibility for any use or action taken by ADI with
         respect to wafers manufactured by CSM, once CSM has satisfactorily
         delivered the said wafers to ADI or ADI's agent(s) in Singapore in
         accordance with the terms of this Agreement.

12.2     ADI hereby agrees that the wafers are [**] for use as [**] in (a) any
         [**]devices or systems; or (b) any [**] devices or systems [**]
         (including but not limited to [**]). CSM

         (i)   [**] devices or systems are devices or systems which are intended
               (aa) for [**], or (bb) to [**], and [**] may result in [**].

         (ii)  A [**] component is any component of a [**] device or system [**]
               may cause the [**].

12.4     ADI shall indemnify, hold harmless and defend CSM, its officers,
         directors, employees and subcontractors from and against any claim,
         suit, demand or action which arises in any way out of, involves or
         relates to an unauthorized use of any wafers or products and ADI shall
         indemnify and hold harmless CSM, its officers, directors, employees and
         subcontractors against any and all direct losses, liabilities, damages,
         awards of settlement (including court costs) and expenses (including
         all reasonable attorney's fees, whether or not legal proceedings are
         commenced) arising from any such claim, suit, demand or action. CSM
         shall notify ADI of any such claim or allegation promptly after
         receiving notice thereof.

12.5     THE TOTAL LIABILITY OF CSM ON ALL CLAIMS OF ANY KIND, WHETHER IN
         CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE
         ARISING OUT OF THE PERFORMANCE OR BREACH OF THIS AGREEMENT OR USE OF
         THE WAFERS SHALL NOT EXCEED [**] BY [**] FROM [**] IN RESPECT OF THE
         [**] OF THE [**] WHICH [**] THE CLAIM.

12.6     In no event shall either Party be liable to the other with respect to
         the subject matter of this Agreement under any contract, tort
         (including negligence), strict liability or other legal or equitable
         theory for any incidental, consequential, special or indirect damages
         of any sort even if such Party has been informed of the possibility of
         such damages.

13.      CONFIDENTIALITY

13.1     All Confidential Information shall be kept confidential by the
         recipient unless or until the recipient Party can reasonably
         demonstrate that any such Confidential Information is, or part of it
         is, in the public domain through no fault of its own, whereupon to the
         extent that it is in the public domain or is required to be disclosed
         by law this obligation shall cease. For the purposes of this Agreement,
         "Confidential Information" shall mean all communications between the
         Parties, and all information and other materials supplied to or
         received by either of them from the other (a) prior to or on the date
         of this Agreement whether or not marked confidential; (b) after the

         other remedy shall be cumulative and shall be in addition to every
         other remedy given hereunder or now or hereafter existing at law, in
         equity, by statute or otherwise. The election of any one or more of
         such remedies by either of the Parties shall not constitute a waiver by
         such Party of the right to pursue any other available remedy.

16.1     If any provision or part of this Agreement is rendered void, illegal or
         unenforceable in any respect under any enactment or rule of law, the
