                                     PART I

ITEM 1:  BUSINESS

     Teradyne, Inc. is a leading manufacturer of automatic test equipment
("ATE") and related software for the electronics and communications industries.
Products include systems to test and inspect:

        - semiconductors ("semiconductor test systems");
        - circuit-boards ("circuit-board test and inspection systems");
        - high speed voice and data communication ("broadband test systems");
          and
        - software ("software test systems").

     On December 29, 2000, Teradyne sold a controlling interest in its software
test business to an investor group led by Matrix Partners of Waltham,
Massachusetts. Teradyne retains a minority ownership in the new company called
Empirix. Software test systems activity is reflected in Teradyne's results for
all periods presented. See "Note D: Acquisitions and Divestitures" in Notes to
Consolidated Financial Statements for further information.

     Teradyne is also a leading manufacturer of backplanes and associated
connectors used in electronic systems ("connection systems"). Circuit-board test
and inspection systems, broadband test systems, and software test systems have
been combined into "other test and inspection systems" for purposes of reporting
Teradyne's operating segments. For financial information concerning these
operating segments, see "Note O: Operating Segment and Geographic Information"
in Notes to Consolidated Financial Statements.

     Statements in this Annual Report on Form 10-K which are not historical
facts, so called "forward looking statements," are made pursuant to the safe
harbor provisions of the Private Securities Litigation Reform Act of 1995.
Investors are cautioned that all forward looking statements involve risks and
uncertainties, including those detailed in Teradyne's filings with the
Securities and Exchange Commission. See also "Item 7: Management's Discussion
and Analysis of Financial Condition and Results of Operations--Certain Factors
That May Affect Future Results."

PRODUCTS

     Semiconductor test systems produced by Teradyne are used by electronic
component manufacturers in the design and testing of a wide variety of
semiconductor products, including logic, memory, mixed signal, and "system on a
chip" integrated circuits. Semiconductor test systems are sold to semiconductor
manufacturers and subcontractors to the semiconductor industry. Semiconductor
manufacturers use Teradyne's semiconductor test systems to:

        - measure product performance;
        - improve product quality;
        - shorten time to market;
        - enhance manufacturability;
        - minimize labor costs; and
        - increase production yields.

     Connection systems provides backplane assemblies, connectors and
electro-mechanical systems integration for customers in the telecom, data
networking, storage, server, and aerospace/defense industries. A backplane is an
assembly into which printed circuit boards are inserted that provides for the
interconnection of electrical signals between the circuit boards and the other
elements of the system. Connection systems provides both a technology advantage
and the benefits of vertical integration to its customers. Connection systems
product technology can be found in diverse products such as Internet routers,
computer servers, mass data storage, telecom switches and aerospace.

     Circuit-board test and inspection systems are used by electronic equipment
manufacturers for the design, inspection, and testing of circuit boards and
other assemblies. Circuit-board test and inspection systems are also sold to
customers across most sectors of the electronics industry and to companies in
other industries that use electronic devices in high volume. Similar to
semiconductor test systems, circuit-board test and inspection systems customers
use their test and inspection systems and related software to increase product
performance, to improve product quality, to shorten time to market, to enhance
manufacturability, to minimize labor costs, and to increase production yields.

     Broadband test systems are used by the communications industry for Internet
testing, customer care and voice network maintenance. Broadband test systems
perform qualification testing for Digital Subscriber Line (DSL) services, assist
customer care centers in isolating network service problems, and perform
integrated surveillance and maintenance for voice networks.

     Software test systems, divested in December 2000 as previously noted, are
used by a number of industries to test communications networks, computerized
telecommunication systems, and web based applications.

     Teradyne's product lines accounted for the following percentage of
consolidated net sales for each of last three years:

SALES AND DISTRIBUTION

     Teradyne's systems are complex and require extensive support both by the
customer and Teradyne. Prices for Teradyne's systems can reach $4 million or
more. In 2000, no single customer accounted for more than 10% of consolidated
net sales. In 2000, Teradyne's three largest customers accounted for 21% of
consolidated net sales.

     We have sales and service offices throughout North America, South East
Asia, Europe, Taiwan, Japan, and Korea as Teradyne's customers outside the
United States are located primarily in those geographic areas. Teradyne sells in
these areas predominantly utilizing a direct sales force. Substantially all of
our manufacturing activities are conducted in the United States. Sales to
customers outside the United States accounted for 54% of consolidated net sales
in 2000, 52% in 1999, and 46% in 1998.

     Teradyne is subject to the inherent risks involved in international trade,
such as:

        - political and economic instability;
        - restrictive trade policies;
        - controls on funds transfer;
        - currency fluctuations;
        - difficulties in managing distributors;
        - potentially adverse tax consequences; and
        - the possibility of difficulty in accounts receivable collection.

     Teradyne attempts to reduce the effects of currency fluctuations by hedging
part of its exposed position and by conducting some of its international
transactions in U.S. dollars or dollar equivalents. See also "Item 7A.
Quantitative and Qualitative Disclosures About Market Risks."

COMPETITION

     We face substantial competition, throughout the world, in each of our
operating segments. Some of these competitors have substantial financial and
other resources to pursue engineering, manufacturing, marketing and distribution
of their products. We also face competition from internal suppliers at several
of our customers. Some of our competitors have introduced or announced new
products with certain performance characteristics which may be considered equal
or superior to those we currently offer. We expect our competitors to continue
to improve the performance of their current products and to introduce new
products or new technologies that provide improved cost of ownership and
performance characteristics. New product introductions by competitors could
cause a decline in sales or loss of market acceptance of our products. Moreover,
increased competitive pressure could lead to intensified price based
competition, which could materially adversely affect our business, financial
condition and results of operations.

BACKLOG

     At December 31, 2000 and 1999, Teradyne's backlog of unfilled orders was as
follows:



                                                        (IN MILLIONS)
                                                    ----------------------
                                                      2000           1999
                                                      ----           ----
                                                              
Semiconductor test systems........................  $  742.1        $700.0
Connection systems................................     534.4         175.4
Other test and inspection systems.................     105.6         104.1
                                                    --------        ------
                                                    $1,382.1        $979.5


     Of the backlog at December 31, 2000, approximately 98% of the semiconductor
test systems backlog, 100% of the connection systems backlog and approximately
83% of the other test and inspection systems backlog are expected to be
delivered in 2001. Teradyne's experience indicates that a portion of orders
included in the backlog may be canceled or rescheduled. We have recently
experienced the rescheduling of delivery dates by some of our customers, and
thus the timing of the delivery of a significant portion of the backlog is
uncertain. There are no seasonal factors related to the backlog.

RAW MATERIALS

     Our products require a wide variety of electronic and mechanical
components. Teradyne can experience occasional delays in obtaining timely
delivery of certain items. Additionally, we could experience a temporary adverse
impact if any of our sole source suppliers ceased to deliver products. Any
prolonged inability to obtain adequate yields or deliveries, or any other
circumstances that would require us to seek alternative sources of supply could
have a material adverse effect on our business, financial condition, and results
of operations.

PATENTS AND LICENSES

     The development of products by Teradyne, both hardware and software, is
largely based on proprietary information. We protect our rights in proprietary
information through various methods such as:

        - copyrights;
        - trademarks;
        - patents and patent applications;
        - software license agreements; and
        - employee agreements.

     Any invalidation of Teradyne's intellectual property rights could have a
material adverse effect on our business.

EMPLOYEES

     As of December 31, 2000 we employed approximately 10,200 people. Since the
inception of Teradyne's business, there have been no work stoppages or other
labor disturbances. Teradyne has no collective bargaining contracts.

ENGINEERING AND DEVELOPMENT ACTIVITIES

     The highly technical nature of Teradyne's products requires a large and
continuing engineering and development effort. Engineering and development
expenditures for new and improved products were approximately $300.9 million in
2000, $228.6 million in 1999, and $195.2 million in 1998. These expenditures
amounted to approximately 10% of consolidated net sales in 2000 and 13% in 1999
and 1998.

ENVIRONMENTAL AFFAIRS

     Teradyne's manufacturing facilities are subject to numerous laws and
regulations designed to protect the environment, particularly from manufacturing
plant wastes and emissions. These laws include:

        - The Comprehensive Environmental Response, Compensation, and Liability
          Act;
        - The Superfund Amendment and Reauthorization Act of 1986;
        - The Occupational Safety and Health Act;
        - The Clean Air Act;
        - The Clean Water Act;
        - The Resource Conservation and Recovery Act of 1976; and
        - The Hazardous and Solid Waste Amendments of 1984.

In the opinion of management, the costs associated with complying with these
laws and regulations have not had and are currently not expected to have a
material effect upon the financial position of Teradyne.

     The number of record holders of Teradyne's Common Stock at February 25,
2001 was 2,406.

     Teradyne has never paid cash dividends because it has been its policy to
use earnings to finance expansion and growth. Payment of future cash dividends
will rest within the discretion of the Board of Directors and will depend, among
other things, upon Teradyne's earnings, capital requirements, and financial
condition. Teradyne presently expects to retain all of its earnings for use in
the business.

ITEM 7:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" (SAB
101). SAB 101 summarizes certain areas of the Staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. Historically, Teradyne recognized revenue from the sales of products
upon shipment, provided that risk of loss had passed to the customer, and
accrued for the costs of installation. Under the new accounting method adopted
retroactive to January 1, 2000, Teradyne recognizes revenue from the sales of
products when both title and risk of loss pass to the customer. Teradyne also
defers the greater of the fair value or the contractual holdback of any
undelivered elements, such as installation services, until the undelivered
elements are delivered. Teradyne previously accounted for contractual acceptance
terms based upon probable achievement of meeting the acceptance criteria.
Teradyne now accounts for acceptance terms based upon whether such contractual
acceptance criteria is objectively demonstrated prior to shipment. During the
fourth quarter of 2000, Teradyne implemented the SEC's SAB 101 guidelines,
retroactive to the beginning of the year. This was reported as a cumulative
effect of a change in accounting principle as of January 1, 2000. The net impact
for fiscal year 2000 of the adoption of SAB 101 on sales, including the amounts
deferred at December 31, 2000 which previously would have been recognized prior
to SAB 101, was not material. The results for the first three quarters of fiscal
year ending December 31, 2000 have been restated in accordance with SAB 101. Pro
forma amounts for the periods beginning before January 1, 2000 have not been
presented as the effect of the change in accounting principle could not be
reasonably determined.

RESULTS OF OPERATIONS:

  2000 compared to 1999

     Sales increased 70% in 2000 to a record $3,043.9 million from $1,790.9
million in 1999. Semiconductor test systems shipments increased by 69% due to
increased sales to semiconductor manufacturers and subcontractors as these
customers increased capacity to meet their customer's requirements. Sales of
connection systems to unaffiliated customers grew 97% as a result of significant
growth in demand from networking, data storage, and other high technology
customers. Other test and inspection systems sales increased 28% from 1999 with
increases in circuit-board test and inspection systems of 19%, broadband test
systems of 10%, and software test systems of 64%. Due to the sale of a majority
interest in the software test business in December 2000, software test systems
revenue will not be reflected on an on-going basis.

     As described in "Item 7: Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Certain Factors That May Affect Future
Results," our business is impacted by the slowdown in economies worldwide. We
are further affected by the cyclical nature of the electronics and semiconductor
industry with recurring periods of over supply. These factors have resulted in a
downturn in the demand for our products. Teradyne does not have visibility as to
the length or severity of the downturn. During this period we expect a decline
in orders and are anticipating a reduction in sales from the fourth quarter 2000
level. Consequently, Teradyne is taking appropriate actions to bring expenses in
line with the economic conditions.

     Income before income taxes and cumulative effect of change in accounting
principle increased $465.8 million from $273.8 million in 1999 to $739.6 million
in 2000. Semiconductor test systems, connection systems, and other test and
inspection systems income before income taxes increased $387.4 million, $91.8
million, and $16.5 million, respectively in 2000 due to increased sales in each
group.

     Incoming orders increased 52% from $2,190.6 million in 1999 to a record
$3,320.9 million in 2000. Orders increased in all operating segments and were
led by a 159% increase in connection systems orders. Semiconductor test systems
orders increased 24%. Broadband test systems orders increased 77% and circuit-
board test and inspection systems and software test systems increased 26% and
70%, respectively. Teradyne's backlog increased 41% to a record $1,382.1
million.

     Costs of sales as a percentage of sales decreased from 59% of sales in 1999
to 55% of sales in 2000. The decrease in cost of sales was primarily due to the
increased utilization of Teradyne's manufacturing overhead as sales volume
increased while certain components of cost of sales remained fixed.

     Engineering and development expenses decreased from 13% of sales in 1999 to
10% of sales in 2000, even though spending increased $72.4 million. The increase
in spending was primarily due to new product development expenses in
semiconductor test systems, and, to a lesser extent, increased expenses related
to product development in connection systems, circuit-board test and inspection
systems, and software test systems.

     Selling and administrative expenses as a percentage of sales decreased from
14% in 1999 to 12% in 2000. Spending increased by $106.2 million year over year
in support of increased semiconductor test systems, connection systems, and
software test systems sales.

     Interest and other income increased $13.4 million to $30.7 million in 2000
compared to 1999. Interest income increased due to an increase in Teradyne's
average invested balances and higher interest rates. Included in interest and
other income is a gain relating to the divestiture of the software test
business. Expenses related to the divestiture are included in selling and
administrative expense. These elements offset and the transaction results in an
immaterial impact to the financial statements.

     Teradyne's effective tax rate was 30% in 2000 and 1999. Teradyne continued
to utilize export sales corporation benefits and other tax benefits to operate
below the U.S. statutory rate of 35%.

  1999 compared to 1998

     Sales increased 20% in 1999 to $1,790.9 million from $1,489.2 million in
1998. Semiconductor test systems shipments increased by 25% due to increased
orders resulting from capacity expansion at semiconductor manufacturers and
subcontractors. Sales of connection systems to unaffiliated customers grew 39%
as a result of continued growth in demand from networking, data storage, and
other high technology customers. Other test and inspection systems sales were
down 18% from 1998 with decreases in broadband test systems of 45% and
circuit-board test and inspection systems of 20%. These decreases were a result
of telecommunication customers reducing investment in traditional voice testing
technology and circuit-board test and inspection systems customers seeking lower
cost solutions and/or new solutions to test increasingly complex circuit-
boards. Other test and inspection systems sales decreases were offset slightly
by an increase of 42% in sales of software test systems to customers within the
telecommunication and web-based application development markets.

     Net income grew $89.6 million to $191.7 million in 1999 from $102.1 million
in 1998. Income before income taxes increased $127.9 million from $145.9 million
in 1998 to $273.8 million in 1999. Semiconductor test systems and connection
systems income before income taxes increased $183.4 million and $29.2 million,
respectively in 1999 due to increased sales. Other test and inspection systems
income before income taxes decreased $46.5 million in 1999 resulting in a loss
before income taxes of $14.3 million in 1999. This decrease in income before
income taxes was due to decreased sales coupled with Teradyne maintaining its
engineering and development of new products.

     Incoming orders increased 82% from $1,206.5 million in 1998 to a record
$2,190.6 million in 1999. Orders increased in nearly all operating segments and
were led by a 130% increase in semiconductor test systems orders. Connection
systems and software test systems orders both increased 34% and circuit-board
test and inspection systems orders increased by a modest 4%. Orders for
broadband test systems decreased 59% in 1999. As a result of record bookings,
Teradyne's backlog increased 69% to a record $979.5 million.

     Costs of sales as a percentage of sales decreased from 64% of sales in 1998
to 59% of sales in 1999. Included in cost of sales in 1998 was a $23.0 million
charge for excess inventory. The charge resulted from the drop in demand for
semiconductor test systems products. Excluding this charge, cost of sales
decreased from 62% to 59%. The decrease in cost of sales was primarily due to
the increased utilization of Teradyne's manufacturing overhead as sales volume
increased while certain components of cost of sales remained fixed.

     Engineering and development expenses were 13% of sales in both 1999 and
1998 representing a year over year increase of $33.4 million. The increase was
primarily due to new product development expenses in semiconductor test systems
although there were increased expenses related to product development in each of
Teradyne's operating segments.

     Selling and administrative expenses were 14% of sales in both 1999 and 1998
representing a year over year increase of $43.5 million. The increase was due to
higher compensation related expenses and spending in support of increased
semiconductor test systems.

     Interest income increased $3.8 million to $17.3 million in 1999 compared to
1998 due to an increase in Teradyne's average invested balances.

     Teradyne's effective tax rate was 30% in 1999 and 1998. Teradyne utilized
export sales corporation benefits and certain research and development tax
credits to operate below the U.S. statutory rate of 35%.

LIQUIDITY AND CAPITAL RESOURCES

     Teradyne's cash, cash equivalents and marketable securities balance
increased $77.0 million in 2000, to $464.4 million. Teradyne has generated cash
from operating activities in each of the last three years and has used that cash
to fund operations. Net income, adjusted to exclude the effects of non-cash
items, provided cash of $500.2 million in 2000, $278.3 million in 1999, and
$186.0 million 1998. Accounts receivable increased 38% in 2000 primarily as a
result of increased shipment volume in the fourth quarter of 2000 compared to
the fourth quarter of 1999. Inventories increased 88% in 2000 to support
Teradyne's backlog commitment. These

                                        10
   12

increases were partially offset by an increase of 67% in accounts payable and
other accruals. In total, other than those assets and liabilities resulting from
investing and financing activities the cash effect of changes in operating
assets and liabilities was: a $29.4 million use in 2000; a $89.1 million source
in 1999; and a $52.6 million source in 1998.

     Teradyne used $312.3 million of cash for investing activities in 2000,
$244.8 million in 1999, and $101.6 million in 1998. Investing activities consist
of purchases, sales, and maturities of marketable securities and purchases of
capital assets to support long-term growth. Capital expenditures increased by
$147.0 million in 2000 compared with 1999 primarily in semiconductor test
systems and connection systems segments. This was due to capacity expansion in
land, buildings and improvements, and machinery and equipment. Capital
expenditures were $298.2 million in 2000, $151.2 million in 1999, and $164.4
million in 1998.

     Teradyne used $97.5 million of cash for financing activities in 2000,
$126.8 million in 1999, and $26.2 million in 1998. Financing activities include
sales and repurchases of Teradyne's common stock, as well as repayments of debt.
During 2000, 1999, and 1998 net common stock activity used $92.2 million, $125.5
million, and $24.6 million of cash, respectively. Since 1996, Teradyne has used
$540.8 million of cash to repurchase 20.0 million shares of its common stock on
the open market.

     Teradyne's available revolving credit line of $120.0 million expired on
January 31, 2001. At expiration of the revolver, any amounts outstanding are
converted into a two year term note. As of December 31, 2000 and 1999, no
amounts were outstanding under this agreement. The revolving credit line was not
renewed in 2001. Teradyne believes its cash, cash equivalents, and marketable
securities balance of $464.4 million, together with other sources of funds,
including cash flow generated from operations, will be sufficient to meet
working capital and capital expenditure requirements for the foreseeable future.

     Inflation has not had a significant long-term impact on earnings.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities -- Deferral of the
Effective Date of FASB Statement No. 133." SFAS No. 137 amends SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" which was issued
in June 1998 and was to be effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. SFAS No. 137 defers the effective date of SFAS
No. 133 to the first quarter of all fiscal years beginning after June 15, 2000.
Teradyne will implement SFAS No. 133, as amended in 2001 and does not expect any
material impact on its financial position or results of operations.

ITEM 7A:  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

CONCENTRATION OF CREDIT RISK

     Financial instruments which potentially subject Teradyne to concentrations
of credit risk consist principally of cash investments, forward currency
contracts, and accounts receivable. Teradyne maintains cash investments
primarily in U.S. Treasury and government agency securities and corporate debt
securities, rated AA or higher, which have minimal credit risk. Teradyne places
forward currency contracts with high credit-quality financial institutions in
order to minimize credit risk exposure. Concentrations of credit risk with
respect to accounts receivable are limited due to the large number of
geographically dispersed customers.

EXCHANGE RATE RISK MANAGEMENT

     Teradyne regularly enters into forward contracts in European and Japanese
currencies to hedge its overseas net monetary position and firm commitments.
Teradyne's firm commitments consist of certain orders received in currencies
other than U.S. dollars. Forward currency contracts generally have maturities of
less than one year. These contracts are used to reduce our risk associated with
exchange rate movements, as gains and losses on these contracts are intended to
offset exchange losses and gains on underlying exposures. Teradyne does not
engage in currency speculation.

                                        11
   13

     At December 31, 2000 the face amount of outstanding forward currency
contracts to buy U.S. dollars for non U.S. currencies was $73.0 million. A 10%
fluctuation in exchange rates for these currencies would change the fair value
by approximately $7.3 million. However, since these contracts hedge non U.S.
currency transactions, any change in the fair value of the contracts would be
offset by opposite changes in the underlying value of the transactions being
hedged. The hypothetical movement was estimated by calculating the fair value of
the forward currency contracts at December 31, 2000 and comparing that with
those calculated using hypothetical forward currency exchange rates.

INTEREST RATE RISK MANAGEMENT

     Due to its short-term duration the fair value of Teradyne's cash and
investment portfolio at December 31, 2000 approximated carrying value. Market
risk was estimated as the potential decrease in fair value resulting from a
hypothetical 10% increase in interest rates for issues contained in the
investment portfolio. The resulting hypothetical fair value was not materially
different from the year-end carrying value.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

     From time to time, information provided by Teradyne, statements made by its
employees or information included in its filings with the Securities and
Exchange Commission (including this Form 10-K and Teradyne's Annual Report to
Shareholders) may contain statements which are not historical facts, so-called
"forward looking statements," which involve risks and uncertainties. In
particular, statements in "Item 1: Business" relating to Teradyne's delivery
time of unfilled orders, and in "Item 7: Management's Discussion and Analysis of
Financial Condition and Results of Operations" relating to the sufficiency of
capital to meet working capital and planned capital expenditures, may be forward
looking statements. Teradyne's actual future results may differ significantly
from those stated in any forward looking statements. Factors that may cause such
differences include, but are not limited to, the factors discussed below. Each
of these factors, and others, are discussed from time to time in Teradyne's
filings with the Securities and Exchange Commission.

OUR BUSINESS IS IMPACTED BY THE SLOWDOWN IN ECONOMIES WORLDWIDE.

     Our business is dependent on current and anticipated market demand for
electronics, which has been impacted by the slowdown in the economies of the
United States, Asia, and elsewhere that began in the latter portions of 2000.
While our diverse businesses may allow us to perform better than some companies
in periods of economic decline, there is no guarantee that this will be the case
currently.

OUR BUSINESS IS DEPENDENT ON THE CURRENT AND ANTICIPATED MARKET FOR ELECTRONICS.

     Our business and results of operations depend in significant part upon
capital expenditures of manufacturers of semiconductors and other electronics,
which in turn depend upon the current and anticipated market demand for those
products. The electronic and semiconductor industry has been highly cyclical
with recurring periods of over supply, which often have had a severe effect on
demand for test equipment, including systems manufactured and marketed by us. We
believe that the markets for newer generations of electronic products will also
be subject to similar fluctuations. We are dependent on the timing of customer
orders and the deferral or cancellation of previous customer orders could impact
our results of operations. We cannot assure that any future increase in sales or
bookings for a calendar quarter will be sustained in subsequent quarters. In
addition, any factor adversely affecting the electronic industry or particular
segments within the electronic industry may adversely affect our business,
financial condition and operating results.

WE HAVE TAKEN AND EXPECT TO CONTINUE TO TAKE REMEDIAL MEASURES TO ADDRESS THE
RECENT SLOWDOWN IN THE MARKET FOR OUR PRODUCTS WHICH COULD HAVE LONG-TERM
EFFECTS ON OUR BUSINESS.

     We have taken and expect to continue to take remedial measures to address
the recent slowdown in the market for our products. In particular, we have
reduced our workforce, frozen hiring, delayed salary increases, reduced senior
managers pay, implemented furloughs, and reduced our planned capital
expenditures and expense budgets. These measures will reduce our expenses in the
face of decreased revenues due to decreased

                                        12
   14

or cancelled customer orders. However, each of these measures could have
long-term effects on our business by reducing our pool of technical talent,
decreasing or slowing improvements in our products, and making it more difficult
for us to respond to customers.

IF WE ARE NOT ABLE TO MEET OUR CUSTOMERS' DELIVERY REQUIREMENTS, IT WOULD HAVE
AN ADVERSE EFFECT ON OUR RESULTS OF OPERATIONS.

     We typically maintain a large multi-week order backlog. If we are unable to
fill these orders and meet customer delivery expectations, customers may cancel
existing orders or fail to place new orders in the future, which would have an
adverse effect on our revenues and results of operations. Factors that affect
our ability to meet customer delivery expectations include:

        - the availability of expanded manufacturing facilities;
        - our ability to attract and retain qualified manufacturing personnel to
          meet anticipated manufacturing levels;
        - the difficulties inherent in manufacturing highly complex products
          that have only recently been introduced; and
        - the availability of components, including semiconductor chips, which
          may be in short supply from time to time.

     In addition, we rely upon third-party contract manufacturers for certain
subsystems used in our products, and our ability to meet customer orders for
those products depends upon the timeliness and quality of the work performed by
these subcontractors, over whom we do not exercise any control.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY, WE MAY LOSE A VALUABLE
ASSET OR MAY INCUR COSTLY LITIGATION TO PROTECT OUR RIGHTS.

     Our products incorporate technology that we protect in several ways,
including patents, copyrights, and trade secrets. While we believe that our
patents, copyrights, and trade secrets have value, in general no single one is
in itself essential. At times we have been notified that we may be in violation
of patents held by others. An assertion of patent infringement against us, if
successful, could have a material adverse effect on our ability to sell our
products, or could require a lengthy and expensive defense which could adversely
affect our operating results.

IF WE FAIL TO DEVELOP NEW TECHNOLOGIES TO ADAPT TO OUR CUSTOMERS' NEEDS AND IF
OUR CUSTOMERS FAIL TO ACCEPT OUR NEW PRODUCTS, IT WILL ADVERSELY AFFECT OUR
REVENUES.

     We believe that our technological position depends primarily on the
technical competence and creative ability of our engineers. Our development of
new technologies, commercialization of those technologies into products, and
market acceptance and customer demand for those products is critical to our
success. Successful product development and introduction depends upon a number
of factors, including:

        - new product selection;
        - development of competitive products by competitors;
        - timely and efficient completion of product design; and
        - timely and efficient implementation of manufacturing and assembly
          processes and product performance at customer locations.

INTENSE COMPETITION IN OUR INDUSTRY MAY AFFECT OUR REVENUES.

     We face substantial competition, throughout the world, in each of our
operating segments. Some of these competitors also have substantial financial
and other resources to pursue engineering, manufacturing, marketing and
distribution of their products. We also face competition from internal suppliers
at several of our customers. Some of our competitors have introduced or
announced new products with certain performance characteristics which may be
considered equal or superior to those we currently offer. We expect our
competitors to continue to improve the performance of their current products and
to introduce new products or

                                        13
   15

new technologies that provide improved cost of ownership and performance
characteristics. New product introductions by competitors could cause a decline
in sales or loss of market acceptance of our products. Moreover, increased
competitive pressure could lead to intensified price based competition, which
could materially adversely affect our business, financial condition and results
of operations.

WE ARE SUBJECT TO RISKS OF OPERATING INTERNATIONALLY.

     We derive a significant portion of our total revenue from customers outside
the United States. Our international sales are subject to significant risks and
difficulties, including:

        - unexpected changes in legal and regulatory requirements and in policy
          changes affecting our markets;
        - changes in tariffs and exchange rates;
        - political and economic instability;
        - difficulties in accounts receivable collection;
        - difficulties in staffing and managing international operations; and
        - potentially adverse tax consequences.

OUR OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY.

     Our quarterly and annual operating results are affected by a wide variety
of factors that could materially adversely affect revenues and profitability,
including:

        - competitive pressures on selling prices;
        - the timing of customer orders and the deferral or cancellation of
          orders previously received;
        - changes in product mix;
        - our ability to introduce new products and technologies on a timely
          basis;
        - introduction of products and technologies by our competitors;
        - market acceptance of our and our competitors' products;
        - fulfilling backlog on a timely basis;
        - reliance on sole source suppliers;
        - potential retrofit costs;
        - the level of orders received which can be shipped in a quarter; and
        - the timing of investments in engineering and development.

     As a result of the foregoing and other factors, we have and may continue to
experience material fluctuations in future operating results on a quarterly or
annual basis which could materially and adversely affect our business, financial
condition, operating results and stock price.

ITEM 8:  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Directors and Shareholders of Teradyne, Inc.:

     In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) present fairly, in all material respects, the
financial position of Teradyne, Inc. and its subsidiaries at December 31, 2000
and 1999, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 2000 in conformity with
accounting principles generally accepted in the United States of America. In
addition, in our opinion, the financial statement schedule listed in the index
appearing under Item 14(a)(2) presents fairly, in all material respects, the
information set forth therein when read in conjunction with the related
consolidated financial statements. These financial statements and financial
statement schedule are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits. We conducted our audits of
these statements in accordance with auditing standards generally accepted in the
United States of America, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

     As discussed in Note C to the consolidated financial statements, during the
year ended December 31, 2000 the Company changed its method of recognizing
revenue.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.  THE COMPANY

     Teradyne, Inc. designs, manufactures, markets, and services test and
inspection systems and related software, and backplanes and associated
connectors. Teradyne had five principal product lines during 2000;

        - semiconductor test systems;
        - connection systems;
        - circuit-board test and inspection systems;
        - broadband test systems; and
        - software test systems.

     Semiconductor test systems are used by electronic component manufacturers
in the design and testing of their products. Connection systems are used
principally for the computer, communications, data networking, and
military/aerospace industries. Connection systems provides both a technology
advantage and the benefits of vertical integration to its customers. A backplane
is an assembly into which printed circuit boards are inserted that provides for
the interconnection of electrical signals between the circuit boards and the
other elements of the system. Circuit-board test and inspection systems are used
by electronic equipment manufacturers for the design, inspection, and testing of
circuit boards and other assemblies. Broadband test systems are used by the
communications industry for Internet testing, customer care and voice network
maintenance. Software test systems, divested at the end of 2000, are used by a
number of industries to test communications networks, computerized
telecommunication systems, and client/server applications.

B.  ACCOUNTING POLICIES

  Basis of Presentation

     The consolidated financial statements include the accounts of Teradyne and
its subsidiaries. All significant intercompany balances and transactions are
eliminated. Certain prior years' amounts were reclassified to conform to the
current year presentation.

  Preparation of Financial Statements

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the dates of
the financial statements and the reported amounts of revenues and expenses
during the reported periods. Actual results could differ from those estimates.

  Recently Issued Accounting Pronouncements

     In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities -- Deferral of the
Effective Date of FASB Statement No. 133." SFAS No. 137 amends SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" which was issued
in June 1998 and was to be effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. SFAS No. 137 defers the effective date of SFAS
No. 133 to the first quarter of all fiscal years beginning after June 15,
2000.Teradyne will implement SFAS No. 133, as amended in 2001 and does not
expect any material impact on its financial position or results of operations.

  Inventories

     Inventories are stated at the lower of cost (first-in, first-out basis) or
market (net realizable value). Inventories include materials, labor, and
manufacturing overhead costs.

B.  ACCOUNTING POLICIES -- (CONTINUED)

  Property, Plant, and Equipment

     Property, plant, and equipment are stated at cost. Leasehold improvements
and major renewals are capitalized and included in property, plant, and
equipment accounts while expenditures for maintenance and repairs and minor
renewals are charged to expense. When assets are retired, the assets and related
allowances for depreciation and amortization are removed from the accounts and
any resulting gain or loss is reflected in operations.

     Teradyne provides for depreciation of its assets principally on the
straight-line method with the cost of the assets being charged to expense over
their useful lives as follows: buildings and improvements -- 5 to 40 years; and
machinery and equipment -- 2 to 10 years.

  Revenue Recognition

     Revenue related to products and software licenses is recognized upon
shipment provided that title and risk of loss has passed to the customer, there
is persuasive evidence of an arrangement, the sales price is fixed or
determinable, collection of the related receivable is reasonably assured and
customer acceptance criteria have been successfully demonstrated. For products
with acceptance criteria that are not successfully demonstrated prior to
shipment, revenue is recognized upon customer acceptance. For multiple element
arrangements, Teradyne defers the greater of the fair value of any undelivered
elements of the contract, such as installation services, or the portion of the
sales price which is not payable until the undelivered elements are delivered.
Teradyne unbundles service revenue and post-contract customer support from
product and software license sales based upon the fair value of those services
where such services are sold separately and recognizes such revenue as the
services are provided or ratably over the period of the related contract, as
applicable. Teradyne's products are generally subject to warranty and such
estimated costs are provided for in cost of sales when product revenue is
recognized. Installation and other services are not essential to the
functionality of the products as these services do not alter the products
capabilities, do not require specialized skills or tools and can be performed by
the customers or other vendors.

     For certain contracts eligible under American Institute of Certified Public
Accountants ("AICPA") Statement of Position No. 81-1, revenue is recognized
using the percentage-of-completion accounting method based upon an
efforts-expended method. In all cases, changes to totals estimated costs and
anticipated losses, if any, are recognized in the period in which determined.

     Deferred revenue includes customer advances and amounts that have been
billed per the contractual terms but have not been recognized as revenue. If a
portion of the sales price is not contractually payable until a future
deliverable is completed, such as installation, such portion of the sales price
is not recorded until such contractual obligation is satisfied.

  Engineering and Development Costs

     Teradyne's products are highly technical in nature and require a large and
continuing engineering and development effort. All engineering and development
costs are expensed as incurred.

  Impairment of Long-Lived Assets

     Teradyne reviews long-lived assets for impairment whenever events or
changes in business circumstances indicate that the carrying amount of the
assets may not be fully recoverable or that the useful lives of these assets are
no longer appropriate. Each impairment test is based on a comparison of the
undiscounted cash flows to the recorded value of the asset. If an impairment is
indicated, the asset is written down to its estimated

                                        21

B.  ACCOUNTING POLICIES -- (CONTINUED)

fair value on a discounted cash flow basis. The cash flow estimates used to
determine the impairment, if any, contain management's best estimates using
appropriate assumptions and projections at that time.

  Income Taxes

     Deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse. The measurement of deferred tax assets is
reduced by a valuation allowance if, based upon weighted available evidence, it
is more likely than not that some or all of the deferred tax assets will not be
realized.

     U.S. Federal taxes are provided for on the retained earnings of non-U.S.
sales and service subsidiaries whose earnings are expected to be remitted to the
United States. U.S. Federal taxes are not provided for on the earnings of a
non-U.S. manufacturing subsidiary which are expected to be reinvested
indefinitely in operations outside the U.S.

  Translation of Non U.S. Currencies

     Assets and liabilities of non U.S. subsidiaries, which are denominated in
currencies other than the U.S. dollar, are remeasured into U.S. dollars at rates
of exchange in effect at the end of the fiscal year except nonmonetary assets
and liabilities which are remeasured using historical exchange rates. Revenue
and expense amounts are remeasured using an average of exchange rates in effect
during the year, except those amounts related to nonmonetary assets and
liabilities, which are remeasured at historical exchange rates. Net realized and
unrealized gains and losses resulting from currency remeasurement are included
in operations.

  Net Income per Common Share

     Basic net income per common share is calculated by dividing net income by
the weighted average number of common shares outstanding during the period.
Diluted net income per common share is calculated by dividing net income by the
sum of the weighted average number of common shares plus additional common
shares that would have been outstanding if potential dilutive common shares had
been issued for granted stock option and stock purchase rights.

  Other Comprehensive Income

     Comprehensive income does not materially differ from net income for the
years ended December 31, 2000, 1999 and 1998.

C.  CHANGE IN ACCOUNTING PRINCIPLE

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" (SAB
101). SAB 101 summarizes certain areas of the Staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. Historically, Teradyne recognized revenue from the sales of products
upon shipment, provided that risk of loss had passed to the customer, and
accrued for the costs of installation. Under the new accounting method adopted
retroactive to January 1, 2000, Teradyne recognizes revenue from the sales of
products when both title and risk of loss pass to the customer. Teradyne also
defers the greater of the fair value or the contractual holdback of any
undelivered elements, such as installation services, until the undelivered
elements are delivered. Teradyne previously accounted for contractual acceptance
terms based upon probable achievement of meeting the acceptance criteria.
Teradyne now accounts for acceptance terms based upon whether such

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

C.  CHANGE IN ACCOUNTING PRINCIPLE -- (CONTINUED)

contractual acceptance criteria is objectively demonstrated prior to shipment.
During the fourth quarter of 2000, Teradyne implemented the SEC's SAB 101
guidelines, retroactive to the beginning of the year. This was reported as a
cumulative effect of a change in accounting principle as of January 1, 2000. The
cumulative effect of the change in accounting principle on prior years resulted
in a charge to income of $64.1 million (net of income taxes of $27.5 million) or
$0.35 per diluted share which has been included in income for the fiscal year
ending December 31, 2000. For the fiscal year ending December 31, 2000, Teradyne
recognized $126.1 million in revenue that is included in the cumulative effect
adjustment as of January 1, 2000. The results for the first three quarters of
fiscal year ending December 31, 2000 have been restated in accordance with SAB
101. Pro forma amounts for the periods beginning before January 1, 2000 have not
been presented as the effect of the change in accounting principle could not be
reasonably determined.

D.  ACQUISITIONS AND DIVESTITURES

     On August 15, 2000, we acquired two California-based companies, both in the
printed circuit board (PCB) industry: Herco Technology of San Diego, CA, a
fabricator of printed circuit boards, and Synthane Taylor of La Verne, CA, which
supplies PCB laminates and is a major supplier to Herco. The acquisitions are
part of the connection systems operating segment. The cost of the acquired
companies was $104.5 million with approximately 1.8 million shares of common
stock issued. The acquisitions have been accounted for by the purchase method of
accounting and accordingly, the results have been included in our consolidated
results of operations from the date of acquisition. Pro forma amounts for the
acquisitions are not included as their effect is not material to the financial
statements. Goodwill of $53.4 million resulting from the acquisitions is being
amortized on a straight-line basis over the estimated life of 15 years.

     The components of the purchase price allocation are as follows:



                                                              (IN THOUSANDS)

          Total.............................................     $104,486


     On December 29, 2000, Teradyne sold a controlling interest in its software
test business to an investor group led by Matrix Partners of Waltham,
Massachusetts for proceeds of approximately $28.7 million. Teradyne has retained
an ownership position of approximately 21% in the new company called Empirix.
Teradyne will, therefore, account for its investment in Empirix under the equity
method of accounting. This transaction did not have a material impact on the
financial statements.

E.  FINANCIAL INSTRUMENTS

  Cash Equivalents

     Teradyne considers all highly liquid investments with original maturities
of three months or less at the date of acquisition to be cash equivalents.

  Marketable Securities

     Teradyne classifies investments in marketable securities as trading,
available-for-sale or held-to-maturity at the time of purchase. There were no
securities classified as trading at December 31, 2000 or 1999. Securities are
classified as held-to-maturity when Teradyne has the positive intent and ability
to hold the

E.  FINANCIAL INSTRUMENTS -- (CONTINUED)

securities to maturity. Held-to-maturity securities are stated at cost with
corresponding premiums or discounts amortized over the life of the investment to
interest income. Securities classified as available-for-sale are reported at
fair value, unless the difference between the fair value and amortized cost is
immaterial in which case they are carried at amortized cost. Unrealized gains or
losses on available-for-sale securities are not material and therefore have not
been recorded. Realized gains and losses and declines in value, if any, judged
to be other-than-temporary on available-for-sale securities are included in
interest income. The cost of securities sold is based on the specific
identification method.

     The fair market value of cash equivalents and short-term and long-term
investments in marketable securities is substantially equal to the carrying
value and represents the quoted market prices at the balance sheet dates. The
short-term investments mature in less than one year. Long-term investments have
maturities of one to ten years. At December 31, 2000 and 1999 these investments
are reported as follows (in thousands):

     For all other balance sheet financial instruments, the carrying amount
approximates fair value.

  Off-Balance Sheet Risk

     Teradyne regularly enters into forward contracts in European and Japanese
currencies to hedge its non U.S. currency net monetary position and firm
commitments. Teradyne's firm commitments consist of certain orders received in
currencies other than U.S. dollars. Forward currency contracts generally have
maturities of less than one year. These contracts are used to reduce Teradyne's
risk associated with exchange rate movements, as gains and losses on these
contracts are intended to offset exchange losses and gains on underlying
exposures. Teradyne does not engage in currency speculation. Gains or losses
associated with the termination of the underlying contract for which a firm
commitment no longer exists are immediately included in selling and
administrative expenses.

     At December 31, 2000, Teradyne had the following forward currency contracts
to buy U.S. dollars for non U.S. currencies with the following notional amounts
totaling $73.0 million; $32.6 million Japanese yen, $5.4 million Euro, $32.1
million British pound sterling, and $2.9 million Swedish Krona. At December 31,
1999 the face amount of outstanding forward currency contracts to buy U.S.
dollars for non U.S. currencies was $62.4 million, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

E.  FINANCIAL INSTRUMENTS -- (CONTINUED)

     The fair value of these contracts as of December 31, 2000 and 1999,
determined by applying year-end currency exchange rates to the notional contract
amounts, represented no unrealized gain or loss in 2000 and a net unrealized
gain of $1.0 million in 1999. Teradyne's policy is to defer gains and losses on
these contracts until the corresponding losses and gains are recognized on the
items being hedged. Both the contract gains and losses and the gains and losses
on the items being hedged are included in selling and administrative expenses.

  Concentration of Credit Risk

     Financial instruments which potentially subject Teradyne to concentrations
of credit risk consist principally of cash investments, forward currency
contracts, and accounts receivable. Teradyne maintains cash investments
primarily in U.S. Treasury and government agency securities and corporate debt
securities, rated AA or higher, which have minimal credit risk. Teradyne places
forward currency contracts with high credit-quality financial institutions in
order to minimize credit risk exposure. Concentrations of credit risk with
respect to accounts receivable are limited due to the large number of
geographically dispersed customers.

F.  DEBT

     Long-term debt at December 31, 2000 and 1999 consisted of the following (in
thousands):

thereafter are: 2001 -- $0.3 million; 2002 -- $0.3 million; 2003 -- $0.3
million; 2004 -- $0.3 million; 2005 -- $0.3 million and $6.9 million thereafter.

  Mortgage Notes Payable

     In 1983, we received a loan of $4.5 million from the Boston Redevelopment
Authority in the form of a 3% mortgage loan maturing March 31, 2013. This loan
is collateralized by a mortgage on Teradyne's property at 321 Harrison Avenue,
which may, at Teradyne's option, become subordinated to another mortgage up to a
maximum of $5.0 million. Interest for the first 4 1/2 years of the note was
capitalized up to a principal amount of $5.0 million. Since September 30, 1987,
Teradyne has been making semi-annual interest payments.

  Revolving Credit Agreement

     Teradyne's available revolving credit line of $120.0 million expired on
January 31, 2001. At expiration of the revolver, any amounts outstanding are
converted into a two year term note. As of December 31, 2000 and 1999, no
amounts were outstanding under this agreement. The revolving credit line was not
renewed in 2001.

  Short-term Borrowings

     The weighted average interest rates on short-term borrowings outstanding as
of December 31, 2000 and 1999 was 1.2% and 1.8%, respectively.

     Options to purchase 1.5 million shares of common stock in 2000, 0.1 million
shares in 1999, and 4.0 million shares in 1998 were outstanding during the years
then ended, but were not included in the year to date calculation of diluted net
income per share because the options' exercise price was greater than the
average market price of the common shares during those periods.

I.  RETIREMENT PLANS

     Teradyne has defined benefit pension plans covering substantially all
domestic employees and employees of certain non U.S. subsidiaries. Benefits
under these plans are based on the employees' years of service and compensation.
Teradyne's funding policy is to make contributions to the plans in accordance
with local laws and to the extent that such contributions are tax deductible.
The assets of these plans consist primarily of equity and fixed income
securities. In addition, Teradyne has an unfunded supplemental defined benefit
plan in the United States to provide retirement benefits in excess of levels
allowed by the Employment Retirement Income Security Act (ERISA).

I.  RETIREMENT PLANS -- (CONTINUED)

     On December 31, 1999, the U.S. defined benefit pension plan (the "U.S.
plan") was amended to update all participating employees accrued benefit to
reflect their average pay over the last five years.

     During the fourth quarter of 1999, Teradyne offered all eligible domestic
employees participating in the U.S. plan a choice; to continue to have benefits
grow in the U.S. plan and continue to be eligible for the current Savings Plan
match described in "Note: L Savings Plan" or to stop growing benefits in the U.S
plan and be eligible for an increased match in the Savings Plan. The accrued
benefit of those employees who selected the enhanced Savings Plan match was
frozen on January 1, 2000 resulting in an insignificant curtailment gain.

     The expense of these defined benefit pension plans and the December 31
balances of plan assets and obligations are shown below (in thousands):

     There is no additional minimum pension liability to be recognized as of
December 31, 2000 and 1999. The projected benefit obligation, accumulated
benefit obligation, and fair value of plan assets for pension plans with
accumulated benefit obligations in excess of plan assets were $22.2 million,
$14.3 million and $3.7 million, respectively, as of December 31, 2000 and $19.9
million, $13.4 million and $3.7 million, respectively, as of December 31, 1999.

J.  COMMON STOCK REPURCHASE PROGRAM

     Teradyne's Board of Directors has authorized the repurchase of 30.0 million
shares of Teradyne's stock on the open market. In 2000, Teradyne repurchased 3.8
million shares at a cost of $147.5 million, increasing the cumulative shares
purchased under this program through 2000 to 20.0 million shares at an aggregate
cost of $540.8 million. Teradyne records treasury stock at its acquisition cost.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

K.  STOCK BASED COMPENSATION

     At December 31, 2000, Teradyne had both stock option plans and stock
purchase plans. Teradyne previously adopted SFAS No. 123 "Accounting for
Stock-Based Compensation" (Statement 123), and as permitted by this standard,
will continue to apply Accounting Principles Board (APB) Opinion 25 and related
interpretations in accounting for its plans. Teradyne is required to disclose
pro forma net income and net income per common share amounts had compensation
costs for Teradyne's stock based compensation plans been determined based on the
fair value at the grant dates for awards under those plans. Had compensation
expense for the stock based compensation plans been consistent with the method
of Statement 123, amounts reported for 2000, 1999, and 1998, respectively would
have been:



                                                            2000      1999     1998
                                                           ------    ------    -----
                                                                      
Income before cumulative effect of change in accounting
  principle..............................................  $458.0    $153.6    $77.8
Income before cumulative effect of change in accounting
  principle per common share -- basic....................  $ 2.64    $ 0.90    $0.46
Income before cumulative effect of change in accounting
  principle per common share -- diluted..................  $ 2.53    $ 0.86    $0.45


     The impact to reported net income and per common share amounts of this pro
forma disclosure are not comparable among 2000, 1999, and 1998 as Statement 123
did not apply to awards prior to 1995. The amounts of this pro forma disclosure
are also not indicative of the impact on net income for future years.

  Stock Option Plans

     Under its stock option plans, all of which are fixed, Teradyne granted
options to directors, officers, certain employees, and other individuals
entitling them to purchase common stock at 100% of market value at the date of
grant. Stock options granted generally have a maximum term of five years and
vest over four years.

     On August 20, 1998, the Stock Option Committee of the Board of Directors
(the "Option Committee") approved a reduction, effective August 27, 1998, in the
exercise price of certain outstanding stock options held by officers and
employees of Teradyne. Action was taken to attempt to restore the long-term
incentive feature of employee stock options. The Option Committee believed that
at their original exercise prices, the disparity between the exercise price of
these options and recent market prices for Teradyne's Common Stock did not
provide meaningful long-term incentive to officers and employees holding these
options to perform to their maximum potential and work toward the success of
Teradyne. In connection with this action we canceled options to purchase 6.4
million shares. The canceled options were originally granted between May 15,
1997 and July 1, 1998 at exercise prices ranging from $18.25 to $20.94 per
share. New options to purchase 6.4 million shares at $9.59 were then granted.
All vesting under the canceled options was lost and new vesting periods were
started. The effect of this option repricing on the above pro forma disclosures
is considered, under Statement 123, a modification of the terms of the
outstanding options. Accordingly, the 2000, 1999, and 1998 pro forma disclosures
include compensation cost for the incremental fair value, under Statement 123,
resulting from such modification.

     The weighted average fair value at date of grant for options granted during
2000, 1999 and 1998 was $15.34, $16.21 and $5.35 per option, respectively. The
fair value of options at date of grant was estimated using the Black-Scholes
model with the following weighted average assumptions:



                                                     2000    1999     1998

  Employee Stock Purchase Plans

     Teradyne has an Employee Stock Purchase plan. Under this plan, eligible
employees may purchase shares of common stock through payroll deductions of up
to 10% of their compensation. The price paid for the common stock is equal to
85% of the lower of the fair market value of Teradyne's common stock on the
first business day in January (July for new hires) or the last business day of
December. In January 2001, Teradyne issued 0.8 million shares of common stock to
employees who participated in the plan during 2000 at a weighted-average price
of $31.98 per share. Currently, there are 1.4 million shares reserved for
issuance.

     The weighted-average fair value of purchase rights granted in 2000, 1999
and 1998 was $17.98, $8.18 and $6.51, respectively. The fair value of the
employees' purchase rights was estimated using the Black-Scholes model with the
following assumptions for 2000, 1999 and 1998, respectively; dividend yield of
0.0% for all

L.  SAVINGS PLANS

     Teradyne sponsors a Savings Plan covering substantially all U.S. employees.
Under Teradyne's original savings plan, employees may contribute up to 12% of
their compensation (subject to Internal Revenue Service limitations). Teradyne
annually matches employee contributions up to 6% of such compensation at rates
ranging from 50% to 100%. Teradyne's contributions vest after two years,
although contributions for those employees with five years of service vest
immediately. In January 2000, Teradyne implemented a second savings plan for
domestic employees who elected to discontinue participation in Teradyne's
retirement plan, see "Note I: Retirement Plans," and all new domestic employees.
Under this new savings plan, domestic employees are eligible for an increased
minimum Teradyne match of 100% on contributions up to 5%. Teradyne has also
established a Supplemental Savings Plan to provide savings benefits in excess of
those allowed by ERISA. The provisions of this plan are the same as the Savings
Plan. Under Teradyne's savings plans, amounts charged to operations were $16.6
million in 2000, $9.8 million in 1999, and $9.3 million in 1998.

M.  STOCKHOLDER RIGHTS PLAN

     Teradyne's Board of Directors adopted a Stockholder Rights Plan on November
16, 2000, under which a dividend of one Common Stock Purchase Right was
distributed for each outstanding share of Common Stock. The plan entitles Stock
Purchase Right holders to purchase shares of Teradyne's common stock for $540
per share subject to adjustment (the "Purchase Price") in certain events, such
as a tender offer to acquire 20% or more of Teradyne's outstanding shares. Under
some circumstances, such as a determination by continuing Directors, that an
acquiring party's interests are adverse to those of Teradyne, the Plan entitles
such holders (other than an acquiring party or adverse party) to purchase Common
Stock (or other securities or consideration owned by Teradyne) having a value
equal to two times the Purchase Price of the right for the Purchase Price. The
Rights expire on November 27, 2010.

     U.S. federal taxes have not been provided for approximately $59.0 million
of cumulative undistributed earnings of a non-U.S. manufacturing subsidiary.
Teradyne intends to reinvest these earnings indefinitely in operations outside
the U.S.

O.  OPERATING SEGMENT AND GEOGRAPHIC INFORMATION

     Teradyne has five principal operating segments which are the design,
manufacturing and marketing of semiconductor test systems, connection systems,
circuit-board test and inspection systems, broadband test systems, and software
test systems, which was divested at the end of 2000. These operating segments
were determined based upon the nature of the products and services offered.
Teradyne has three reportable segments; semiconductor test systems segment,
connection systems segment, and other test and inspection systems segment. The
other test and inspection systems segment is comprised of circuit-board test and
inspection systems, broadband test systems, and software test systems.

     Teradyne evaluates performance based on several factors, of which the
primary financial measure is business segment income before taxes. The
accounting policies of the business segments are the same as those described in
"Note B: Accounting Policies". Intersegment sales are accounted for at fair
value as if sales were to third parties. During 2000 and 1998 no individual
customer accounted for more than 10% of consolidated net sales. During 1999,
principally all of Teradyne's operating segments reported sales to Motorola Inc.
accounting for a total of 11% of consolidated net sales.

(1) Sales are attributable to geographic areas based on location of customer
    site.

     Because a substantial portion of Teradyne's sales are derived from the
sales of product manufactured in the United States, long-lived assets located
outside the United States are less than 10% of total assets.
