Analog Devices, Inc.
Notes to Condensed Consolidated Financial Statements
July 29, 1995





Note 1 - In the opinion of management, the information furnished in the
accompanying financial statements reflects all adjustments, consisting only of
normal recurring adjustments, which are necessary to a fair statement of the
results for this interim period and should be read in conjunction with the most
recent Annual Report to Stockholders.

Note 2 - Certain amounts reported in the previous year have been reclassified
to conform to the 1995 presentation.

Note 3 - Commitments and Contingencies

As previously reported in the Company's Annual Report on Form 10-K for the
fiscal year ended October 29, 1994 and as set forth in Item 1, "Legal
Proceedings" in the Company's Forms 10-Q for the fiscal quarters ended January
28, 1995 and April 29, 1995, the Company has been engaged in patent
infringement litigation with Texas Instruments, Inc. ("TI") and a related
enforcement proceeding brought by the International Trade Commission ("ITC"),
and antitrust litigation with Maxim Integrated Products, Inc. ("Maxim").

The Company was a defendant in two lawsuits brought in Texas by TI, alleging
patent infringement, including patent infringement arising from certain plastic
encapsulation processes, and seeking an injunction and unspecified damages
against the Company. The alleged infringement of one of these patents is also
the subject matter of a proceeding brought by TI against the Company before
the ITC. On January 10, 1994, the ITC brought an enforcement proceeding against
the Company alleging that the Company had violated the ITC's cease and desist
order of February 1992 (as modified in July 1993), and seeking substantial
penalties against the Company for these alleged violations. In addition, in
June 1992, the Company commenced a lawsuit against TI in Massachusetts alleging
certain TI digital signal processors infringed one of the Company's patents.

Effective April 1, 1995, the Company and TI settled both Texas lawsuits and the
Massachusetts lawsuit principally by means of a royalty-free cross license of
certain of the Company's and TI's patents. On April 24, 1995, the Company
filed with the ITC a motion to terminate the ITC enforcement proceeding on the
grounds that further action by the ITC is unnecessary in light of the Company's
settlement with TI. On May 8, 1995, an Administrative Law Judge issued a
recommended determination to the ITC to grant the Company's motion to
terminate, and that motion is pending before the ITC.

The Company is a defendant in a lawsuit brought by Maxim seeking an injunction  
against, and claiming damages for, alleged antitrust violations and unfair      
competition in connection with distribution arrangements between the Company
and certain distributors. Maxim alleged that certain distributors ceased doing
business with Maxim as a result of the distribution arrangements between the
distributors and the Company, resulting in improper restrictions to Maxim's
access to channels by which it distributes its products. Maxim asserted actual
and consequential damages in the amount of $14.1 million and claimed
restitution and punitive damages in an unspecified amount. Under applicable
law, Maxim would receive three times the amount of any actual damages suffered
as a result of any antitrust violation. On September 7, 1994, Maxim's claim was
dismissed for lack of evidence. Maxim has appealed this ruling and briefing of
the appeal was concluded in March 1995. No hearing on this appeal has yet been
scheduled.

Although the Company believes it should prevail in these matters, the Company is
unable to determine their ultimate outcome or estimate the ultimate amount of
liability, if any, at this time. An adverse resolution of these matters could
have a material adverse effect on the Company's consolidated financial position
or on its consolidated results of operations or cash flows in the period in
which the matters are resolved.

Item 2. Management's Discussion and Analysis of Financial Condition and
Results of Operations

Third Quarter of Fiscal 1995 Compared to the Third Quarter of Fiscal 1994

Net sales of $246.3 million for the third quarter of fiscal 1995 grew $49.2
million or 25.0% from net sales of $197.1 million for the third quarter of      
fiscal 1994. Third quarter sales growth was principally attributable to
significant increases in sales volumes of both standard linear IC and
system-level IC products as worldwide demand for precision integrated circuits
exceeded the industry's expectations and capacity. Sales of the Company's
standard linear IC products, the largest and most profitable part of the
Company's business, was up more than 35% from last year's third quarter. With
the exception of hard disk drive products, revenues from system-level IC
products, including both general-purpose digital signal processing and mixed
signal ICs, grew approximately 46% year over year. Revenues from disk drive
manufacturers declined $13.1 million compared to the third quarter of fiscal
1994 as the market continues to move rapidly to digital PRML channels.
Assembled product sales decreased approximately 9% from the third quarter of
fiscal 1994.

Demand for the Company's standard linear IC and system-level IC products was
broad based across all served application markets and geographies with the
strongest end user market growth in computers, wireless communications, high
speed digital communications, automatic test equipment and other
industrial-market applications. The distributor channel continued to have a
very positive effect on sales growth, particularly for standard linear IC
products, as worldwide sales through distribution increased approximately 67%
from the same period last year to comprise approximately 44% of total sales in
the third quarter of fiscal 1995. Distribution has become the fastest growing
channel for the Company's standard linear IC products.

Geographically, the largest year-over-year sales gains were registered in North
American distribution, Europe and Japan with a weaker average dollar exchange
rate contributing to a portion of the international sales increase.

Assuming continued increases in demand, further increases in sales will be
constrained in the near term by the Company's manufacturing capacity. See
"Liquidity and Capital Resources" below for a discussion of the Company's
efforts to address its capacity issues.

Gross margin increased to 50.8% of sales from 49.3% in the third quarter of
fiscal 1994, driven by a shift in the mix of products sold towards
higher-margin standard linear IC products. Gross margin on all IC products,
which include both standard linear and system-level ICs, was approximately 55%
of sales compared to 51% for the year ago quarter.

R&D expenses for the third quarter of fiscal 1995 increased 28.8% over the same
quarter last year to 14.2% of sales as the Company continued to fund the most
promising initiatives in new product and process development.  Selling,
marketing, general and administrative expense (SMG&A) growth was held to 9.3%
over the amount in the third quarter of fiscal 1994 despite a weaker dollar, as
the Company continued to constrain spending growth to a rate significantly
below sales growth. As a result, the SMG&A-to-sales ratio decreased to 19.2%
from 22.0% in the third quarter of fiscal 1994.





                                       8
<PAGE>   9
Operating profit rose 60.4% to 17.3% of sales compared to 13.5% of sales in
fiscal 1994's third quarter reflecting the combination of accelerated demand
for the Company's products, improved gross margin and continuing commitment to
growing expenses more slowly than sales.

Nonoperating expenses decreased $1.1 million in total, aided in large part by a
decrease in interest expense and an increase in interest income. The decrease
in interest expense related primarily to the maturity of a $20 million term
loan in the first quarter of fiscal 1995 while the increased interest income
reflected an increase in investment rates.

The effective income tax rate increased from 23.5% for the year ago quarter to
26.0% for the third quarter of fiscal 1995 due to a shift in the mix of
worldwide income to higher tax rate jurisdictions.

The growth in sales and improved operating performance yielded a 61.5% increase
in net income which rose from $19.7 million or $0.25 per share for the
year-earlier period to $31.8 million or $0.40 per share for the third quarter
of fiscal 1995.

Third Quarter of Fiscal 1995 Compared to the Second Quarter of Fiscal 1995

Net sales rose from $230.0 million for the second quarter of fiscal 1995 to
$246.3 million for the third quarter of fiscal 1995, an increase of $16.3       
million or 7.1% as the strong order rate experienced during the second quarter
continued into the third quarter.  The sales increase resulted largely from
increased sales volumes of standard linear IC products, which grew 12% from the
prior quarter, as the use of high performance standard linear IC components in
faster growing segments of the industrial, computer, communications and
consumer markets has become more pervasive. This trend together with the
Company's broader participation in the distributor channel and a strong demand
environment have accelerated the growth of the Company's standard linear IC
products. Sales were strong throughout all geographic regions including North
America, both in the Company's distributor and OEM businesses, Europe and
Japan.

The increased mix of standard linear IC sales had a beneficial impact on gross
margin which improved slightly from 50.6% in the second quarter to 50.8% in the
third quarter. R&D expenses for the third quarter rose $1.8 million from the
second quarter but as a percentage of sales decreased from 14.5% for the second
quarter of fiscal 1995 to 14.2% for the third quarter of fiscal 1995.  SMG&A
expenses declined as a percentage of sales to 19.2% from 19.8% for the second
quarter of fiscal 1995. Higher sales, improved gross margin and further
reduction in total operating expenses as a percentage of sales generated a
sequential gain in operating income of 13.8% with operating income reaching
17.3% of sales compared to 16.3% in the preceding quarter.

Interest income was reduced from $2.0 million for the second quarter to $1.7
million for the third quarter of fiscal 1995 due to a lower average amount of
cash and cash equivalents. The effective tax rate increased to 26.0% compared
to 24.0% for the prior quarter, reflecting a change in the mix of worldwide
income. The improved operating performance led to a sequential improvement in
net income of  10.7% to $31.8 million or $0.40 per share compared to $28.7
million or $0.36 per share for last quarter.

First Nine Months of Fiscal 1995 Compared to the First Nine Months of Fiscal
1994

Net sales of $684.4 million increased $114.2 million or approximately 20% from
the same period of fiscal 1994. Worldwide market demand in the semiconductor
industry increased throughout fiscal 1995 with the Company benefiting from this
demand both in its standard linear IC and system-level IC product areas. The
sales increase was primarily volume-based and was widespread across all product
lines, markets and geographies. Sales of standard linear ICs increased
approximately 28% while sales of system-level IC products, excluding hard disk
drive products, increased approximately 41%. Sales of hard disk drive products
decreased $27.3 million year over year. Total IC sales, representing both
standard linear and system-level ICs constituted approximately 91% of total
sales for the first nine months of fiscal 1995, continuing the long-term trend
of IC sales becoming a larger portion of the Company's revenues.
Sales of assembled products declined approximately 10% compared to the same
period last year.

The highest growth for both the Company's standard linear IC and system-level
IC products was in applications targeted for fast growing sectors of the
communications and computer markets. Sales growth for the Company's core
standard linear products was also very strong for the first nine months of
fiscal 1995 in the Company's traditional industrial and instrumentation markets
for such products as high-performance op amps and converters and pin
electronics for automatic test equipment.

Sales to North American and international customers increased 16% and 23%,
respectively, over the same period last year with the translation of local
currency sales to a weaker average U.S. dollar accounting for some of this
improvement. The distributor channel was a major contributor to sales growth in
North America as well as in Europe and Japan, especially for standard linear
products, as worldwide sales through distribution increased 53% compared to the
year ago period. For the first nine months of fiscal 1995, approximately 42% of
the Company's sales were derived from sales through distributors.

Gross margin increased two points from 48.6% for the first nine months of
fiscal 1994 to 50.6% of sales for the first nine months of fiscal 1995. This
increase resulted primarily from significantly stronger sales of higher-margin
standard linear IC products.

R&D expenses increased $20.7 million or 26.6% over the prior year reflecting
continued investment in high growth initiatives in the computer,
communications, consumer and automotive markets. As a percentage of sales, R&D
increased from 13.6% last year to 14.4% for the first nine months of fiscal
1995. SMG&A expense growth was held to 8.0% over these periods, leading to a
reduction in SMG&A as a percentage of sales from 22.2% for the first nine
months of fiscal 1994 to 20.0% for the first nine months of fiscal 1995
consistent with the Company's focus on maintaining tight control on operating
expenses in order to provide additional operating profit leverage as revenues
grow.

Operating profit reached $111.2 million or 16.2% of sales for the first nine
months of fiscal 1995, an increase of 52.7% from $72.8 million or 12.8% of
sales for the first nine months of fiscal 1994. This performance gain reflected
growth in sales, improvement in gross margin and a slower rate of SMG&A expense
growth versus sales.

Nonoperating expenses decreased $5.1 million year-to-year due in large part to  
increased interest income on a higher average level of cash investments and a
higher weighted average investment rate. A reduction in interest expense from
$5.5 million to $3.2 million related primarily to the maturity of a $20 million
term loan early in the first quarter of fiscal 1995 also contributed to the
decrease in nonoperating expenses. The effective income tax rate increased to
24.8% from 22.8% for the year ago period due to a change in the mix of
worldwide profits.

Net income grew 59.3% to $84.1 million or $1.06 per share compared to $52.8
million or $0.68 per share for the first nine months of fiscal 1994. As a
percentage of sales, net income improved to 12.3% from 9.3% for the
year-earlier period.

Liquidity and Capital Resources

At July 29, 1995, cash and cash equivalents and short-term investments totaled
$128.5 million, compared to $181.8 million and $157.8 million at the end of the
fourth and third quarters of fiscal 1994, respectively. The $53.3 million
decrease in cash, cash equivalents and short-term investments from the end of
the fourth quarter of fiscal 1994 resulted from cash used to fund a portion of
capital expenditures, the maturity of the Company's $20.0 million term loan in
the first quarter of fiscal 1995, and an investment made in an external wafer
foundry in the second quarter of fiscal 1995 as discussed below. Cash, cash
equivalents and short-term investments, in the aggregate, decreased $29.3
million compared to the third quarter of fiscal 1994 as the continued
generation of cash flow from operations was more than offset by a significant
increase in additions to property, plant and equipment associated with capacity
expansion.

For the first nine months of fiscal 1995, the Company generated cash flow from
operations of $120.3 million or 17.6% of sales compared to $115.0 million or
20.2% of sales for the same period of fiscal 1994. The change in operating
cash flow compared to the first nine months of fiscal 1994 principally
reflected higher net income offset in large part by an increase in working
capital requirements including increases in accounts receivable and
inventories. Cash flow from operations generated for the third quarter of
fiscal 1995 was $31.6 million or 12.8% of sales versus $38.6 million or 16.8%
of sales for the prior quarter and $39.6 million or 20.1% of sales for the
third quarter of fiscal 1994. The decrease in operating cash flows compared to
both of these quarters was mainly attributable to higher net working capital
requirements in the third quarter of fiscal 1995, as increased net income was
more than offset by growth in accounts receivable.

Accounts receivable of $185.7 million increased $7.4 million or 4.2%, $23.4
million or 14.4% and $31.4 million or 20.3% from the end of the second quarter
of 1995, the fourth quarter of 1994 and the third quarter of 1994,
respectively. The increase in accounts receivable in the third quarter of
fiscal 1995 compared to the fourth and third quarters of fiscal 1994 reflected
the higher sales levels combined with the translation of local currency
denominated receivables to a weaker U.S. dollar, particularly in Japan. The
increase in accounts receivable from the second quarter to the third quarter of
fiscal 1995 was attributable to the rise in sales.  As a percentage of
annualized quarterly sales, however, accounts receivable was reduced to 18.8%
from 19.4%, 20.0% and 19.6% for the previous quarter and the fourth and third
quarters of 1994, respectively.

Inventories rose $5.1 million during the first nine months of 1995 as a result
of heightened customer demand and the need to improve response times for
incoming orders.  Inventories at the end of the third quarter of fiscal 1995
were relatively flat to the second quarter of fiscal 1995 as well as to the
year ago quarter. As a percentage of annualized quarterly sales, inventories
decreased to 13.8% from 14.6% for the prior quarter, 16.1% for the fourth
quarter of 1994 and 17.0% for the year-earlier quarter.

As previously discussed above and in the Company's "Management Discussion and
Analysis of Financial Condition and Results of Operations" contained in its
Form 10-Q for the fiscal quarter ended April 29, 1995, the Company's revenue
and order growth has been capacity constrained. The Company has several
capacity expansion programs under way that should provide the Company
substantially greater capacity during fiscal 1996.

Cash flow from operations together with cash on hand for both the third quarter
and first nine months of fiscal 1995 were used largely to fund net additions to
property, plant and equipment of $43.4 million and $145.8 million,
respectively. Capital expenditures were significantly higher than the
comparable periods of 1994 with the majority of these expenditures related to
capacity expansion including the new 6-inch, 0.6-micron wafer module at the
Company's wafer fabrication facility in Limerick, Ireland, primarily for
advanced mixed-signal products, and the ongoing conversion of the Company's
Wilmington, Massachusetts fab to provide new six-inch capability, primarily for
high-speed linear products. The module in Limerick, which has been supported in
part by grants from the Irish government, is currently expected to be on line
in early 1996 while the module in Wilmington is currently expected to be on
line during the second half of 1996. In addition, during the third quarter of
fiscal 1995, the Company completed the purchase of assets of an existing
six-inch wafer fab from Performance Semiconductor Corporation in Sunnyvale,
California. This facility is now undergoing rehabilitation and conversion to
advanced linear technology.

In addition to the ongoing capital expansions in Ireland, Massachusetts and
California, the Company has also shifted production of disk drive IC products
from its facility in Ireland to external foundries in order to free up internal
capacity.  These actions in total, which principally support the production of
higher margin linear IC products, are expected to provide upside capacity in
fiscal 1996 that could accommodate the higher growth the Company is currently
experiencing in its core linear products, if such growth continues. Other
programs aimed at providing additional internal capacity include an expansion
of the Company's assembly and test facilities in the Philippines and a building
expansion program at the Company's facility in North Carolina to provide
capability to produce newer hybrids and multi-chip modules for communications
and other high growth applications.





                                       12
<PAGE>   13
The Company's programs to address capacity shortages related to its external
wafer supply, particularly for system-level and digital signal processing ICs
for products in the computer and communications sectors, include its expanded   
relationship with Taiwan Semiconductor Manufacturing Company (TSMC), the
Company's primary wafer foundry, to provide higher capacity over the 1996-1999
time frame. Under the agreement with TSMC, the Company will make option fees
aggregating $22.4 million to secure this additional capacity which are payable
over the period through 1999. Also, to secure access to additional external
wafer capacity, the Company invested $14 million in the second quarter of
fiscal 1995 in an external foundry, Chartered Semiconductor in Singapore. The
Company anticipates investing an additional $6 million in Chartered
Semiconductor in fiscal 1996. This supply agreement is scheduled to begin
providing access to eight-inch, 0.5-micron wafer capacity in 1996. The TSMC
option fees and Chartered Semiconductor investment described above will be
amortized over the related wafer output periods.

Despite these measures, which together are expected to provide increased
capacity in 1996, the Company currently expects that demand, based on recent
growth levels, will continue to exceed available supply for the balance of 1995
and into early 1996. The Company believes its current capacity is sufficient to
grow revenues by approximately 20-25% for the fourth quarter of fiscal 1995,
compared to the same period last year, assuming demand continues strong during
this period.

The Company currently anticipates that capital spending, including expenditures
related to the new wafer modules in Limerick and in Wilmington and the
Company's other internal capacity expansion programs, will be approximately
$190 million in fiscal 1995 and approximately the same level in fiscal 1996. As
a result of internal expansion, depreciation expense is expected to be
incrementally higher in fiscal 1996 as these planned additions begin to ramp
up.

At July 29, 1995, substantially all of the Company's lines of credit were
unused, including its four-year, $60 million credit facility.

The Company believes that its strong financial condition, existing sources of
liquidity, available capital resources and cash expected to be generated from
operations leave it well positioned to obtain the funds required to finance its
capital expenditure plan and to meet its current and future business
requirements.

Litigation

As set forth in Note 3 to the Condensed Consolidated Financial Statements
contained in this Form 10-Q for the fiscal quarter ended July 29, 1995, the
Company is engaged in an enforcement proceeding brought by the International
Trade Commission related to patent infringement litigation with Texas
Instruments, Inc., and antitrust litigation with Maxim Integrated Products,
Inc.

Although the Company believes it should prevail in these matters, the Company
is unable to determine their ultimate outcome or estimate the ultimate amount
of liability, if any, at this time. An adverse resolution of these matters
could have a material adverse effect on the Company's consolidated financial
position or on its consolidated results of operations or cash flows in the
period in which the matters are resolved.

4.   OTHER PURCHASE TERMS AND CONDITIONS

     The Analog/TSMC Agreement for Wafer Production entered into concurrently
     with this Agreement will apply to all purchases of wafers by Analog From
     TSMC, except that the provisions of this Agreement will supersede the above
     Agreement for Wafer Production with respect to the subject matter hereof.

5.   OBLIGATION TO PAY OPTION FEE FOR OPTION CAPACITY

     Analog agrees to pay to TSMC the Option Fee in the amount of ****** per
     Wafer Equivalent for the right to purchase the Option Capacity pursuant to
     this Agreement. The Option Fee is set forth in Exhibit D, and it shall be
     paid in cash by no later than every June 30 during the term of this
     Agreement for the Option Capacity of the following year. Subject to
     Sections 7 and 8 below, the Option Fee for any given year, once paid, shall
     be non-refundable for any cause, and will be credited at the rate of ******
     per Wafer Equivalent against the prices of wafers purchased by Analog from
     TSMC when purchased from the Option Capacity provided by TSMC for that
     given year under this Agreement.

6.   Analog further agrees to deliver to TSMC, within ************* following
     the Effective Date, four (4) promissory notes each in an amount of the
     Option Fee due every year, and payable to TSMC on each June 30, which
     promissory notes are in the form of Exhibit E. The promissory notes shall
     be returned by TSMC to Analog within ************** upon receipt of the
     corresponding Option Fee by TSMC.

7.   FAILURE TO PURCHASE THE OPTION CAPACITY; FIRST RIGHT OF
     REFUSAL

     (a)  If in any calendar year, for any reason, Analog is not able to use or
          purchase all or a portion of the Analog Committed Capacity of that
          year, or any other year(s) during the term of this Agreement, Analog
          shall promptly notify TSMC of such in writing and first offer TSMC
          such Capacity for sales to any third parties. TSMC may, at its option,

          accept such offer, in whole or in part, within thirty (30) days
          following Analog's notification, and if TSMC so accepts, the
          corresponding Option Fee, if paid, will be returned without interest
          and, if not paid, will be cancelled and the corresponding Promissory
          Note(s) returned to Analog. In the event that TSMC decides not to
          accept such offer, Analog may assign this Agreement (including the
          right to purchase the Analog Committed Capacity for the remaining term
          of this Agreement) to any third parties acceptable to TSMC, within two
          months upon TSMC's written notice that it will not accept such offer,
          and if Analog fails to do so, Analog shall be liable for the Option
          Fee for the remaining term of this Agreement under Section 5 above,
          and TSMC is entitled to sell or use any such unused capacity
          thereafter.

     (b)  Any of Analog's right or obligation set forth in this Section 7(a)
          shall not affect its obligation to pay the Option Fee pursuant to
          Section 5 above, except that if this Agreement is assigned to any
          third parties acceptable to TSMC pursuant to this Section 7(a) above,
          such third parties shall pay the Option Fee and abide by the terms and
          conditions of this Agreement.

     (c)  Notwithstanding the foregoing, if in any calendar year, for any
          reason, Analog does not purchase the Wafer Equivalent of the X% Base
          Capacity for that year, then the Base Capacity and X% Base Capacity
          for each following year of this Agreement shall be reduced by a
          percentage equal to the *******************************
          ************************.

8.   TERM AND TERMINATION

     (a)  The term of this Agreement shall commence on the Effective Date, and
          continue until December 31, 1999.

     (b)  TERMINATION BY TSMC FOR ANALOG's FAILURE TO PAY THE OPTION FEE

          TSMC may terminate this Agreement if Analog fails to pay the Option
          Fee pursuant to Section 5 above, and does not cure or remedy such
          breach within **************** of receiving written notice of such
          breach.

     (c)  TERMINATION FOR OTHER BREACH OR FOR BANKRUPTCY

    3.1 The parties shall agree upon the Process for the manufacture of the
        Products in accordance with the Qualification plan described in Exhibit
        3. 1A and upon the parametric, electrical, process flow, quality, and
        reliability specifications, as well as other standards or requirements
        that the parties deem necessary ("Quality and Reliability
        Specifications"). The Quality and Reliability Specifications shall
        constitute the contractual standards according to which Analog Devices
        shall conduct acceptance of the Products. The Quality and Reliability
        Specifications shall be reduced into writing and attached hereto as
        Exhibit 3.1B.

    3.2 After the Process and the Quality and Reliability Specifications are
        agreed upon in accordance with Subsection 3.1, TSMC will provide Analog
        Devices with such amount of test wafers as Analog Devices may require
        for qualification, at the purchase prices specified in Section 8. Within
        ******** upon receipt of the test wafers, Analog Devices shall inform
        TSMC in writing of whether or not such test wafers meet the Quality and
        Reliability Specifications, and if affirmative, full qualification is
        completed and TSMC will proceed to produce the Products pursuant to the
        purchase order or orders issued by Analog Devices and accepted by TSMC
        under Section 4 below, if any. If no notification is received by TSMC
        during the time period specified in the preceding sentence, full
        qualification shall be deemed accomplished. In the event that the test
        wafers do not meet the Quality and Reliability Specifications, the
        parties will work together in good faith to achieve full qualification.

    3.3 Prior to the completion of the full qualification, Analog Devices may,
        by giving at least ****** notice to TSMC, terminate the production of
        any test wafers or risk starts specified in Subsection 2.4, and TSMC
        will do so following the completion of the process steps at which such
        test wafers or risk starts reside at the time of receiving such notice.
        Analog Devices shall pay TSMC for all the test wafers and/or risk starts
        so affected, and the prices for such wafers and/ or risk starts shall be
        the respective purchase prices specified in Section 8, equitably
        prorated based on the completed stage of production.

4.0 PRODUCTION AND SUPPLY

    4.1 Using the Process, qualified to the requirements both of TSMC and of
        Analog Devices as listed in Exhibit 3.1A, TSMC will manufacture those
        integrated circuits of Analog Devices described in individual Purchase
        Order documents accepted by TSMC. For those products and processes which
        are no longer in active manufacturing, TSMC and Analog Devices shall
        both agree before the obsolescence and destruction of existing tooling
        and recipes for their manufacture. Analog Devices reserves the right to
        witness the destruction of tooling consigned to TSMC for manufacture of
        Analog Devices products. TSMC agrees to provide a minimum of *********
        ********** advance notice of the obsolescence of any process, for which
        a compatible process would not be offered, with a phase-down plan to be
        mutually agreed upon.

    4.2 Subject to TSMC's qualification of the Process, TSMC will produce Analog
        Devices' requirements for Wafers, up to a maximum number of wafers per
        week as agreed upon from time to time.

        4.2.1   If Analog Devices fails to load to the committed levels in any
                given year for which there is no specific other agreement on
                committed capacity levels, TSMC is obligated for the following
                year to only increase the committed capacity by *** from actual
                volume.

        4.2.2   Analog Devices offers TSMC ************ to be Analog Devices'
                primary source for **************** ********* for which TSMC
                provides a competitive capability, price, delivery, and other
                terms.

        4.2.3   In any given year for which there is no specific other agreement
                on committed capacity levels, TSMC agrees not to hold Analog
                Devices' capacity to some arbitrary percentage of TSMC's total
                capacity.

        4.2.4   If ADI decides to build its own Fab of significant size or
                invest in a TSMC competitor, ADI agrees to notify TSMC
                *********** and TSMC and ADI would negotiate in good faith to
                modify their commitments.

    4.3.0   Purchase orders shall be provided to TSMC by Analog Devices
            consistent with the current forecast. The sequence of events is as
            follows:

        4.3.1   **** times a year, Analog Devices will forecast * ******** in
                the future (below numbered ** to **, indicating successive
                ******** into the future from the date of the forecast). TSMC
                will allow

                Analog Devices to at least change its actual volumes, for any
                calendar *******, either up or down by the following percentages
                from the previous ********* forecasts.

</TABLE>

                For ** and **, Analog Devices agrees to order wafers within
                these limits of its forecast and the percentages indicated
                above.

                For ** and **, Analog Devices has the right to reduce volume
                below that determined by the *** ******* rules if their market
                price is the primary determinate for reducing the volume. TSMC
                has the right, after Analog Devices presents its price
                requirements, to accept the new price requiring Analog Devices
                to raise the volume back to the minimum under the ***********
                rules, or to accept the new Analog Devices forecast. For this
                purpose, Analog Devices agrees to provide ********** notice
                before the start of any ******* for which a reduced volume limit
                is being sought.

                For ** and **, Analog Devices agrees to give *** ****** notice
                of any forecast reduction below the *****************. If the
                forecast drops below the six quarter rules, Analog Devices must
                revise the ********* forecast consistent with the new
                requirements.

        4.3.2   TSMC will allow these changes as long as they do not exceed TSMC
                maximum capacity commitment. TSMC will provide its ******
                capacity plan, annually to Analog Devices.

        4.3.3   It is agreed and understood that the purchase of Wafers and/or
                Devices pursuant to this Agreement shall be accomplished by
                means of Analog Devices individual purchase orders and/or other
                release documents (hereinafter collectively referred to as
                "purchase orders"). The purchase orders placed by Analog Devices
                will be open purchase orders for a fixed quantity of Wafers,
                covering the minimum guaranteed volume per *****. TSMC reserves
                the right to refuse purchase orders beyond the TSMC commitment
                of capacity.

    4.4 Analog Devices will accept deliveries made in installments from TSMC,
        upon mutual agreement to be determined in each case. Such partial
        shipments will be billed as made; and payments, therefore, are subject
        to the terms of payment noted below. Individual fab lots shall be
        complete within a single shipment, unless agreed to by Analog Devices in
        each case.

    4.5 If the cumulative quantity shipped by TSMC of each product ordered by
        Analog Devices is within +/- * percent of the quantity ordered, such
        quantity shall constitute compliance with Analog Devices order. Billing
        for partial orders shipped as described in this paragraph will be at the
        established purchase price per unit times the total quantity of units
        delivered.

    4.6 If Analog Devices determines that modifications to the specifications
        are required, including modifications to mask tooling, process or
        testing, TSMC agrees to initiate corrective action within
        ******************** upon receipt of notification at appropriate TSMC
        manufacturing location and to complete such modifications within a
        reasonable period of time after notification in writing by Analog
        Devices. The parties will negotiate adjustment to price and delivery
        schedule as well as charges for retooling costs if warranted by such
        modifications. Initiation of corrective action would include halting
        manufacturing of affected material at the appropriate stages of
        production and other action as mutually deemed appropriate.

    4.7 Analog Devices may add or substitute similar product types using the
        process flows approved by Analog Devices and TSMC for existing
        production at any time, provided that the agreed upon quantities of
        Wafer shipments required by Analog Devices will not be in excess of
        those previously agreed upon except with the consent of TSMC. A similar
        product type is one which is manufactured using the same process, or a
        similar process in the same production facility as mutually agreed to be
        acceptable, and in accordance with the same qualification plan as Analog
        Devices integrated circuits currently manufactured by TSMC under this
        Agreement. TSMC will provide Device and Wafers of such similar product
        types under the same terms as specified herein.

    4.8 If Wafers or Devices fail to meet Quality and Reliability
        specifications, and in Analog Devices reasonable opinion such failure
        appears material, Analog Devices may request TSMC to stop production. If
        TSMC is unable to correct such failures within ************ ****, Analog
        Devices may cancel such particular orders. Analog Devices will notify
        TSMC in writing of its intention to suspend or cancel such orders and
        will include any substantiating data.

5.0 ON-SITE INSPECTION AND VENDOR INFORMATION

    5.1 Analog Devices representatives shall be allowed to visit TSMC's FAB and
        test facilities during normal working hours upon reasonable notice to
        TSMC.

     3.8  For Engineering lots and on request, the WAT SUMMARY REPORT will also
          include all other tested parameters which do NOT have PASS/FAIL
          criteria, as per the usual TSMC procedures. Specific requirements
          regarding these added tests for any lot shall be communicated to TSMC
          with the order.

     3.9  Only wafers that have met the required criteria and are documented as
          having passed are to be shipped to Analog Devices or a location
          designated by Analog Devices.

          In the case of wafers being shipped to a designated location, it is
          the responsibility of TSMC to ensure Parametric information has been
          sent to the Analog Devices PRODUCT ENGINEER as designated in the
          Purchase Requisition.

     3.10 TSMC must provide ********* monitor information on electromigration,
          step coverage, metal integrity, gate oxide integrity, and Vt stability
          for the relevant processes, listed in APPENDIX 1. TSMC shall specify
          normal control limits for these monitors. Any process, for which no
          product using that process was ordered or delivered for ********, does
          not require ********* monitors.

     3.11 TSMC will work with ADI to jointly determine defect density and defect
          size distribution for all wafer fabrication areas. This data will be
          used to continuously validate the yield models.

     3.12 OZONE DEPLETING SUBSTANCES (O.D.S.) must not be used in the
          manufacturing and/or cleaning of components for Analog Devices, Inc.
          after 1/1/93.

          3.12.1  Use of OZONE DEPLETING SUBSTANCES in manufacture and / or
                  cleaning occurs when any component or part of a product is
                  ever in contact with ANY QUANTITY of an OZONE DEPLETING
                  SUBSTANCE anywhere in the manufacturing chain.

          3.12.2  The definitions of Ozone Depleting substances are as follows:

                  CLASS 1 SUBSTANCES are those which significantly cause or
                  contribute to harming the OZONE LAYER and have an OZONE
                  DEPLETING POTENTIAL (O.D.P.) GREATER THAN OR EQUAL TO 0.2.
                  These substances, which include all ISOMERS, are separated
                  into five groups:

                  GROUP 1 - CFC 11,12,113,114,115
                  GROUP 2 - HALON 1211,1301,2402 
                  GROUP 3 - OTHER CFC's with ONE, TWO or THREE CARBON ATOMS.
                  GROUP 4 - CARBON TETRACHLORIDE

                  GROUP 5 - METHYL CHLOROFORM (except the 1,1,2 ISOMER)

                  CLASS 2 SUBSTANCES are those which are known or may be
                  reasonably anticipated to cause or contribute to harmful
                  effects on the Ozone layer. These substances include all
                  ISOMERS of HCFC's having ONE, TWO or THREE CARBON ATOMS.

                  +++++++++++++++++++++++++++++++++++++++++++++
                  ALL CLASS 1 AND CLASS 2 SUBSTANCES ARE
                  CONSIDERED TO BE OZONE DEPLETING SUBSTANCES.
