A. The Company
- --------------

     Teradyne, Inc. (the "Company") designs, manufactures, markets, and services
test systems and related software, and backplanes and associated connectors. The
Company has five  principal  products;  semiconductor  test  systems,  backplane
connection systems, circuit-board test systems, telecommunications test systems,
and software test systems.

     Semiconductor test systems are used by electronic  component  manufacturers
in the design and testing of their products.  Backplane  connection  systems are
used  principally  for  the  computer,  communications,  and  military/aerospace
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.  Circuit-board test systems
are used by  electronic  equipment  manufacturers  for the design and testing of
circuit boards and other assemblies.  Telecommunication test systems are used by
telephone   operating  companies  for  the  testing  and  maintenance  of  their
subscriber telephone lines and related equipment. Software test systems are used
by  a  number  of  industries  to  test  communications  networks,  computerized
telecommunication systems, and web based applications.

B. Accounting Policies
- ----------------------

   Basis of Presentation

The condensed  consolidated interim financial statements include the accounts of
the Company and its  subsidiaries.  All  significant  intercompany  balances and
transactions have been eliminated.  The year-end condensed  consolidated balance
sheet data were derived from audited  financial  statements,  but do not include
all disclosures required by generally accepted accounting principles.

   Preparation of Financial Statements

     The accompanying  condensed  consolidated  interim financial statements are
unaudited.  However, in the opinion of management,  all adjustments  (consisting
only of normal recurring accrual entries)  necessary for a fair statement of the
results for the interim  periods have been made.  The  preparation  of financial
statements in conformity with generally accepted accounting  principles requires
management to make estimates and assumptions that 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.

   Revenue Recognition

     Product  revenue is recognized  upon shipment.  The Company's  products are
generally subject to warranty, and the Company provides for such estimated costs
when product revenue is recognized.  The Company  recognizes  service revenue as
the services are provided or ratably over the period of the related contract, as
applicable.  The  Company  unbundles  service  revenue  from  product  sales and
maintenance  services from software license fees based upon amounts charged when
such elements are separately sold. 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 total estimated
costs and  anticipated  losses,  if any, are  recognized  in the period in which
determined.

   Other Comprehensive Income

     Comprehensive  income does not materially  differ from net income,  for the
three months ended April 2, 2000 and April 4, 1999.

C. 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 be effective  for all fiscal  quarters of all fiscal years  beginning
after June 15, 2000. Accordingly,  the Company will adopt the provisions of SFAS
No. 133 for its 2001 fiscal  year.  SFAS No. 133  requires  that all  derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current  earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and the type of hedge  transaction.  Management is currently
evaluating  the  effects of this  change on its  recording  of  derivatives  and
hedging activities.

     On March 24, 2000 the  Securities  and Exchange  Commission  ("SEC") issued
Staff Accounting Bulletin ("SAB") No. 101A which amended Question 2 of Section B
of Topic 13 of the Staff  Accounting  Bulletin  Series.  SAB No. 101A delays the
implementation  date of SAB 101 "Revenue  Recognition  in Financial  Statements"
until the Company's  second  quarter of the fiscal year 2000. SAB 101 summarizes
the SEC's view in applying generally accepted accounting  principles to selected
revenue  recognition issues. The Company has not completed its evaluation of SAB
101 and is therefore unable to determine its impact.

     In  March  2000,  the  Financial  Accounting  Standard  Board  issued  FASB
Interpretation  No. 44,  "Accounting  for Certain  Transactions  Involving Stock
Compensation  - an  interpretation  of APB Opinion  No. 25" ("FIN  44").  FIN 44
clarifies the application of APB Opinion No. 25 and among other issues clarifies
the  following:  the  definition  of an employee  for  purposes of applying  APB
Opinion No. 25; the  criteria  for  determining  whether a plan  qualifies  as a
noncompensatory plan; the accounting consequence of various modifications to the
terms of previously  fixed stock options or awards;  and the  accounting  for an
exchange  of stock  compensation  awards in a  business  combination.  FIN 44 is
effective July 1, 2000, but certain  conclusions in FIN 44 cover specific events
that occurred  after either  December 15, 1998 or January 12, 2000.  The Company
does not  expect  the  application  of FIN 44 to have a  material  impact on the
Company's financial position or results of operations.

E. Operating Segment Information
- --------------------------------

     The Company has five principal  operating  segments   which are  the design,   manufacturing  and  marketing of  semiconductor
test  systems,  backplane  connection  systems,  circuit-board test  systems,   telecommunication   test systems, and software test
systems. These operating  segments  were  determined  based upon the nature of the  products and services  offered.  The Company has
three   reportable segments;  semiconductor test systems segment,  backplane  connection  systems  segment,  and other test systems
segment. The other test systems segment is comprised of  circuit-board test systems,  telecommunication test  systems, and software
test systems.

     The  Company  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" in the Company's Annual Report on Form 10-K  for the year ended December 31, 1999.  Intersegment  sales are accounted for
at  fair value as if sales were to third parties.  Operating  segment   information for the  three months ended  April 2, 2000 and
April 4, 1999 follows (in thousands):

Results of Operations
- ---------------------

     Sales increased 88% in the first quarter of 2000 to a record $648.1 million
from $344.5  million in the first  quarter of 1999.  Semiconductor  test systems
shipments  increased  130% due to  increased  orders  resulting  from  continued
capacity expansion at semiconductor  manufacturers and subcontractors.  Sales of
backplane  connection systems to unaffiliated  customers grew 48% as a result of
continued  growth  in demand  from  networking,  data  storage,  and other  high
technology  customers.  Other test  systems  sales  increased  4% from the first
quarter of 1999.

     Net income  grew $91.1  million to $109.1  million in the first  quarter of
2000 from $18.0 million in the first quarter of 1999. Income before income taxes
increased  $130.1  million  from $25.7  million in the first  quarter of 1999 to
$155.8  million in the first  quarter of 2000.  Semiconductor  test  systems and
backplane connection systems income before income taxes increased $132.7 million
and $12.2  million,  respectively  in the first quarter of 2000 due to increased
sales.

     Incoming orders  increased 131% from $444.1 million in the first quarter of
1999 to a record $1,024.2 million in the first quarter of 2000. Orders increased
in all operating  segments and were led by a 147% increase in semiconductor test
systems orders.  Backplane  connection  systems and software test systems orders
from  unaffiliated  customers both increased  123% and 86%,  respectively  while
circuit-board test systems and  telecommunication  test systems orders increased
by 17% and 5%, respectively. The Company's backlog was a record $1,355.6 million
at the end of the first quarter of 2000 compared with $679.4  million at the end
of the first quarter of 1999.

     Costs of sales as a percentage of sales  decreased from 64% of sales in the
first quarter of 1999 to 54% of sales in the first quarter of 2000. The decrease
in  cost  of  sales  was  due  to the  increased  utilization  of the  Company's
manufacturing  overhead as sales volume  increased  while certain  components of
cost of sales remained fixed. In addition,  there was a favorable  change in the
mix as sales of semiconductor  test systems,  whose margins are generally higher
than those of backplane  connection systems,  were a greater percentage of total
Company sales.
                                       10



     Engineering and development expenses decreased to 11% of sales in the first
quarter of 2000 from 14% of sales in the first quarter of 1999 while  increasing
$21.3 million.  This spending growth was primarily due to increased  investments
in new products in each operating segment.

     Selling and administrative  expenses decreased to 12% of sales in the first
quarter of 2000 from 16% of sales in the first quarter of 1999 while  increasing
$24.5  million.  This  spending  growth was due to higher  compensation  related
expenses  and  spending  in support of  increased  semiconductor  test  systems,
software test systems, and backplane connections system sales.

     Interest income increased $1.2 million to $5.0 million in the first quarter
of 2000  compared  to the  first  quarter  of  1999  due to an  increase  in the
Company's average invested balances.

     The Company's  effective  tax rate was 30% in the first  quarter 2000.  The
overall  effective  rate for the year  ended  1999 was  also  30%.  The  Company
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
- -------------------------------

     The Company's cash,  cash  equivalents  and marketable  securities  balance
decreased  $1.6 million in the first  quarter of 2000,  to $385.8  million.  The
Company  generated cash from operating  activities of $49.6 million in the first
quarter of 2000 and $35.5 million in the first quarter of 1999.  Cash  generated
from net income, excluding the effects of non-cash items, was $133.3 million and
$39.8 million for the first quarters of 2000 and 1999, respectively.  Changes in
operating assets and liabilities used cash of $83.6 million in the first quarter
of 2000 as a result of increases in working capital to support  increased sales.
In 1999, changes in assets and liabilities used cash of $4.3 million.

     The Company  used $96.3  million of cash for  investing  activities  in the
first quarter of 2000 and $28.5 million in the first quarter of 1999.  Investing
activities consist of purchases,  sales, and maturities of marketable securities
and  purchases  of  capital  assets  to  support   long-term   growth.   Capital
expenditures  were $46.8  million in the first quarter of 2000 and $24.8 million
in the first quarter of 1999.

     The Company used $4.5 million of cash for financing activities in the first
quarter  of 2000  and  provided  $3.3  million  in the  first  quarter  of 1999.
Financing  activities  include  issuance of the  Company's  common stock through
employee  stock  option and stock  purchase  plans,  repurchase  of common stock
through a stock buyback program and repayments of debt. During the first quarter
of 2000 net common stock  activity used $4.5 million.  The first quarter of 1999
net common stock  activity  provided $3.7 million.  Since 1996,  the Company has
used $439.6  million of cash to  repurchase  16.9  million  shares of its common
stock on the open market.

     The Company believes its cash, cash equivalents,  and marketable securities
balance of $385.8 million,  together with other sources of funds, including cash
flow generated from  operations and the available  borrowing  capacity of $120.0
million under its line of credit  agreement,  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.

Certain Factors That May Affect Future Results
- ----------------------------------------------
     From time to time, information provided by the Company,  statements made by
its employees or  information  included in its filings with the  Securities  and
Exchange Commission (including this Form 10-Q and the Company's Annual Report to
Shareholders)  contains  statements  that are not purely  historical,  so-called
"forward  looking  statements,"  which  involve  risks  and  uncertainties.   In
particular,  forward  looking  statements may include  projections,  plans,  and
objectives for the Company's business,  financial condition,  operating results,
future  operations,  future economic  performance or statements  relating to the
sufficiency of capital to meet working capital and planned capital expenditures.
The Company's  actual future results may differ  materially from those stated in
any forward looking statements. Factors that may cause such differences include,
but are not limited to, the factors discussed below. These factors,  and others,
are discussed from time to time in the Company's filings with the Securities and
Exchange  Commission,  including in the Company's Annual Report on Form 10-K for
the year ended December 31, 1999.

     The  Company's  future  results  are  subject  to  substantial   risks  and
uncertainties.  The  Company's  business  and  results of  operations  depend in
significant part upon capital  expenditures of manufacturers of  semiconductors,
which  in turn  depend  upon the  current  and  anticipated  market  demand  for
semiconductors  and products  incorporating  semiconductors.  The  semiconductor
industry has been highly cyclical with recurring  periods of over supply,  which
often have had a severe effect on the  semiconductor  industry's demand for test
equipment,  including  systems  manufactured  and marketed by the  Company.  The
Company believes that the markets for newer generations of  semiconductors  also
will be subject  to similar  fluctuations.  There can be no  assurance  that any
increase in  semiconductor  test  systems  bookings  for a  particular  calendar
quarter will be sustained in subsequent quarters. Any factor adversely affecting
the  semiconductor  industry or  particular  segments  within the  semiconductor
industry may adversely affect the Company's  business,  financial  condition and
                                       11


operating results.  In addition,  the Company believes many of its semiconductor
test systems  customers  place orders in  anticipation  of  manufacturing  their
products. If these customers manufacture fewer products than expected,  they may
attempt to cancel  their  semiconductor  test  systems  orders with the Company.
These  cancellations  could  have a  material  adverse  effect on the  Company's
financial  condition  in  future  quarters.   Finally,   the  Company  has  made
substantial  investments  in  fixed-cost  infrastructure.  If the  semiconductor
industry  experiences  a  downturn,  the Company  may have  difficulty  reducing
expenses in a timely manner,  which could have a material  adverse effect on its
profitability.

     The Company recently has experienced  record order backlog.  If the Company
is unable to timely manufacture  products to fill these orders and meet customer
expectations,  customers may cancel  existing orders or fail to place new orders
in the future,  which would have an adverse effect on the Company's revenues and
results of operations.  Factors that affect the Company's ability to timely fill
customer orders include: the availability of expanded manufacturing  facilities;
the Company's 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,  the  Company  relies  upon
third-party contract  manufacturers for certain subsystems used in its products,
and the Company's  ability to meet customer  orders for those  products  depends
upon the timeliness  and quality of the work performed by these  subcontractors,
over whom the Company does not exercise any control.

     The Company relies on certain intellectual property protections to preserve
its  intellectual  property rights,  including  patents,  copyrights,  and trade
secrets.  While the Company  believes  that its patents,  copyrights,  and trade
secrets have value, in general no single one is in itself essential. The Company
believes  that its  technological  position  depends  primarily on the technical
competence and creative ability of its research and development personnel.  From
time to time the Company is notified that it may be in violation of patents held
by  others.  An  assertion  of  patent  infringement  against  the  Company,  if
successful, could have a material adverse effect on the Company or could require
a lengthy and  expensive  defense  which could  adversely  affect the  Company's
operating results.

     The   development   of  new   technologies,   commercialization   of  those
technologies into products,  and market acceptance and customer demand for those
products is critical to the Company's success.  Successful  product  development
and introduction depends upon a number of factors,  including the ability of the
Company to hire and retain qualified engineers, new product design,  development
of  competitive  products by  competitors,  timely and  efficient  completion of
product  design,  timely  and  efficient  implementation  of  manufacturing  and
assembly processes and product performance at customer locations.  The Company's
failure to successfully develop,  introduce and produce in commercial volume new
or enhanced  products,  or failure of the market to accept these new or enhanced
products could materially affect the Company's financial condition.

     The Company faces  substantial  competition,  throughout the world, in each
operating  segment.   Some  of  these  competitors  have  substantially  greater
financial and other resources to pursue  engineering,  manufacturing,  marketing
and  distribution of their  products.  The Company also faces  competition  from
internal  suppliers  at  several  of its  customers.  Certain  of the  Company's
competitors  have introduced or announced new products with certain  performance
characteristics  which may be  considered  equal or superior to those  currently
offered by the  Company.  The  Company  expects its  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 the  Company's  existing  products.
Moreover,  increased  competitive pressure could lead to intensified price based
competition,  which could materially  adversely  affect the Company's  business,
financial condition and results of operations.

     The  Company  derives  a  significant  portion  of its total  revenue  from
customers  outside  the  United  States.  International  sales  are  subject  to
significant  risks,   including  unexpected  changes  in  legal  and  regulatory
requirements  and policy  changes  affecting the Company's  markets,  changes in
tariffs, exchange rates and other barriers,  political and economic instability,
difficulties  in  accounts  receivable  collection,   difficulties  in  managing
distributors  and   representatives,   difficulties  in  staffing  and  managing
international operations,  difficulties in protecting the Company's intellectual
property and potentially adverse tax consequences.

     The Company's  semiconductor  test systems  operating  segment  generates a
significant  portion of its  revenue  from  customers  operating  in South Asian
countries and Taiwan. Although the economies of South Asian countries and Taiwan
have  stabilized  to some  degree  since mid  fiscal  1998,  if these  economies
deteriorate the negative economic  developments would increase the likelihood of
either a direct or indirect  adverse  impact on the Company's  future  operating
results.

     The Company's 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
and  cancellation  of customer  orders;  changes in product mix;  the  Company's
ability  to  introduce  new  products  and   technologies  on  a  timely  basis;
introduction of products and technologies by the Company's  competitors;  market
acceptance of the Company's and its 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,  the  Company may  experience  material  fluctuations  in future
operating  results on a quarterly  or annual  basis which could  materially  and
adversely affect its business, financial condition,  operating results and stock
price.
