                                 TERADYNE, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)



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

     Teradyne, Inc. (the "Company") designs, manufactures, markets, and services
electronic test systems and related software used by component  manufacturers in
the  design  and  testing  of  their   products  and  by  electronic   equipment
manufacturers for the design and testing of circuit boards and other assemblies.
Manufacturers use such systems and software to increase product performance,  to
improve   product   quality,   to   shorten   time   to   market,   to   enhance
manufacturability,  to conserve labor costs, and to increase  production yields.
The Company's  electronic systems are also used by telephone operating companies
for the testing and maintenance of their subscriber  telephone lines and related
equipment.

     The Company also manufactures backplane connection systems, principally for
the computer, telecommunications, and military/aerospace industries. A backplane
is a panel that  supports  the  circuit  boards in an  electronic  assembly  and
carries the wiring that connects the boards to each other and to other  elements
of a system.

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

   Basis of Presentation

     The consolidated  financial  statements include the accounts of the Company
and its  subsidiaries.  All significant  intercompany  balances and transactions
have been eliminated.  Certain prior years' amounts were reclassified to conform
to the current year presentation. The year-end condensed 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 financial statements are unaudited.
However,  in the opinion of  management,  all  adjustments  (consisting  only of
normal  recurring  accrual  entries)  necessary for a fair  presentation of such
information  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.

C.   Recently Issued Accounting Standard
- ----------------------------------------

         In February  1997,  The  Financial  Accounting  Standards  Board issued
Statement on Financial  Accounting  Standards No. 128, Earnings per Share, which
specifies  the  computation,   presentation,  and  disclosure  requirements  for
earnings per share. The statement is effective for periods ending after December
15, 1997,  including  interim  periods.  The adoption of this statement will not
have a material impact on reported net income per common share.

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

     Sales of $336.7  million in the third quarter of 1997 were $75.0 million or
29% above those of the third quarter of 1996.  The period to period  increase in
sales was  primarily  due to an  increase in  shipments  of  semiconductor  test
systems.  Sales  increased  16% in the third  quarter  of 1997  over the  second
quarter of 1997 as incoming orders of semiconductor  test systems  increased for
the fourth  consecutive  quarter.  As a result of the  increase  in sales in the
third  quarter of 1997 compared to 1996,  income  before income taxes  increased
$31.5 million to $57.4 million. For the first nine months of 1997, income before
income  taxes  (excluding  the  effect of a pre-tax  nonrecurring  product  line
consolidation  charge of $34.1  million  taken in the  second  quarter  of 1996)
decreased $46.1 million to $123.3 million.

                                       7



     Incoming  orders were $461.0  million in the third quarter of 1997 compared
to $215.2 million in the third quarter of 1996. The increase in incoming  orders
was led by a 286% increase in semiconductor  test systems orders.  The Company's
backlog was $796.1 million at the end of the third quarter of 1997 compared with
$454.3 million at the end of third quarter of 1996.

     Cost of products sold as a percentage of sales  decreased from 63% of sales
in the third  quarter  of 1996 to 57% of sales in the third  quarter  of 1997 as
sales volume increased and certain overhead  components of cost of products sold
remained  fixed.  Cost of products sold as a percentage of sales  (excluding the
product line consolidation charge),  increased from 57% in the first nine months
of 1996 to 58% in the first nine  months of 1997.  Included  in cost of sales in
the first nine months of 1996 is a $34.1 million  charge in connection  with the
consolidation of the VLSI product lines of Megatest and Teradyne.

     Engineering and development expenses,  as a percentage of sales,  decreased
from 13% in the  third  quarter  of 1996 to 12% in the  third  quarter  of 1997.
Selling and administrative  expenses,  as a percentage of sales,  decreased from
16% in  the  third  quarter  of  1996  to 15% in  the  third  quarter  of  1997.
Engineering and development and selling and  administrative  spending  increased
$6.7 million and $10.2 million,  respectively, in the third quarter of 1997 over
the same  period in 1996.  These  spending  increases  were at rates of increase
below the third quarter year over year sales increase and were primarily related
to the development and introduction of new semiconductor test systems products.

     Engineering and development expenses,  as a percentage of sales,  increased
from 12% for the first nine  months of 1996 to 14% for the first nine  months of
1997. Selling and administrative  expenses, as a percentage of sales,  increased
from 14% for the first nine  months of 1996 to 16% for the first nine  months of
1997.  These percentage of sales increases in the first nine months of 1997 over
the year earlier  period  resulted from increased  spending on  development  and
introduction of new  semiconductor  test systems  products  coupled with a sales
decrease.

     Interest income in the third quarter of 1997 was flat compared to the third
quarter of 1996.  Interest  income for the nine  months of 1997  increased  $3.1
million to $16.1 million over the year-earlier  period due to an increase in the
Company's average invested balances and interest yields.

     The Company's effective income tax rate was 34% in the first nine months of
1997 (which is the current  estimate  for the fiscal  year)  compared to 33% for
fiscal  1996.  The  increase  in the 1997  fiscal  rate is due to an  in-process
technology  charge related to the acquisition of Softbridge,  Inc., taken in the
second quarter of 1997, which is non-deductible for income tax purposes.

Liquidity and Capital Resources
- -------------------------------

     The Company's cash, cash  equivalents,  and marketable  securities  balance
decreased  $111.1 million in the first nine months of 1997.  Contributing to the
decrease in cash, cash equivalents, and marketable securities was cash flow used
in  operations  of $3.2  million,  the  expenditure  of  $73.9  million  to fund
additions to property,  plant and equipment, the use of $73.6 million to acquire
2.0 million  shares of the Company's  common stock,  and the use of $1.9 million
for principal  debt payments.  The Company  generated cash of $41.5 million from
the sale of stock to  employees  under  the  Company's  stock  option  and stock
purchase plans in the first nine months of 1997.

     Inventories as a percentage of annualized quarterly revenues increased from
14.4% at December 31,  1996,  to 16.6% at  September  28,  1997,  as the Company
expanded material  purchases to support the shipment of new products.  Property,
plant and equipment expenditures relate primarily to the expansion of production
capacity to accommodate higher volumes and the introduction of new products.

     The Company believes its cash, cash  equivalents and marketable  securities
balance of $320.4 million,  together with other sources of funds,  including 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 over the next twelve months.

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, the Company's  Annual Report on
Form  10-K,  and the  Company'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 2: 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 expenditure  requirements may be forward looking statements.
The Company'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 the Company's  filings
with the Securities and Exchange Commission.

     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  will
also be subject to similar  fluctuations.  The most recent downturn  experienced
during 1996 contributed to a 37% decline in  semiconductor  test systems orders.
There can be no  assurance  that any  increase  in  semiconductor  test  systems
bookings for a calendar  quarter will be sustained in  subsequent  quarters.  In
addition,   any  factor  adversely  affecting  the  semiconductor   industry  or
particular  segments within the semiconductor  industry may adversely affect the
Company's business, financial condition and 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;  potential  retrofit
costs;  the level of orders received which can be shipped in a quarter;  and the
timing of investments in engineering and development. In particular, the Company
has  introduced a  significant  number of new,  complex test systems in 1996 and
1997, and there can be no assurance that the Company will not experience  delays
in  shipment  of such  products  or that such  products  will  achieve  customer
acceptance.  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.
