                                     PART I
 
ITEM 1:  BUSINESS
 
     Teradyne, Inc. is a manufacturer of electronic test systems and backplane
connection systems used in the electronics and telecommunications industries.
For financial information concerning these two industry segments, see "Note M:
Industry Segment and Geographic Information" in Notes to Consolidated Financial
Statements. Unless the context indicates otherwise, the term "Company" as used
herein includes Teradyne, Inc. and all its subsidiaries.
 
     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 the Company 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."
 
ELECTRONIC TEST SYSTEMS
 
     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.
 
     Electronic test systems produced by the Company include: (i) test systems
for a wide variety of semiconductors, including digital, analog, and mixed
signal integrated circuits ("semiconductor test systems"), (ii) test systems for
circuit boards and other assemblies ("circuit-board test systems"), (iii) test
systems for telephone lines and networks ("telecommunications test systems"),
and (iv) software test programs for communications networks, computerized
telecommunications systems and other software products ("software test"). The
Company's test systems are all controlled by computers, and programming and
operating software is supplied both as an integral part of the product and as a
separately priced enhancement. Semiconductor test systems accounted for 64% of
consolidated net sales in 1996, 69% in 1995, and 62% in 1994. Circuit-board test
systems accounted for 13% of consolidated net sales in 1996, 11% in 1995, and
15% in 1994. Telecommunications test systems accounted for 7% of consolidated
net sales in 1996 and 1995, and 6% in 1994. Software test accounted for 1% of
consolidated net sales in 1996.
 
     The Company's systems are extremely complex and require extensive support
both by the customer and by the Company. Prices for the Company's systems range
from less than $100,000 to $5 million or more.
 
BACKPLANE CONNECTION SYSTEMS
 
     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. The Company produces both printed circuit and metal backplanes,
along with mating circuit-board connectors. Backplanes are custom configured to
meet specific customer requirements and includes the manufacture of fully
integrated electronic assemblies that incorporate backplane, card cage, cabling,
and related design and production services. Backplane connection systems
accounted for 15% of consolidated net sales in 1996, 13% in 1995, and 17% in
1994.

                              MARKETING AND SALES
 
MARKETS
 
     The Company sells its products across most sectors of the electronics
industry and to companies in other industries that use electronic devices in
high volume. No single customer accounted for 10% or more of consolidated net
sales in 1996. In 1996, the Company's three largest customers accounted for less
than 25% of consolidated net sales.
 
     Direct sales to United States government agencies accounted for less than
2% of consolidated net sales in 1996, 1995, and 1994. Sales are also made within
each of the Company's segments to customers who are government contractors.
Approximately 15% of backplane connection system sales and less than 10% of
electronic test systems sales fell into this category during 1996.
 
     The Company's customers outside the United States are located primarily in
Europe, the Asia Pacific region, and Japan. The Company sells in these areas
both directly and through non U.S. sales subsidiaries. Substantially all of the
Company's manufacturing activities are conducted in the United States.
 
     Sales to customers outside the United States accounted for 54% of
consolidated net sales in 1996, 52% in 1995, and 46% in 1994. Sales to such
customers from locations outside the United States accounted for less than 10%
of consolidated net sales in all periods presented. Identifiable assets of the
Company's non U.S. locations, consisting principally of operating assets used in
support of domestic export sales, approximated $130.3 million at December 31,
1996, $125.2 million at December 31, 1995, and $94.5 million at December 31,
1994. Of these identifiable assets at December 31, 1996, $82.3 million were in
Europe, $40.6 million were in Japan, and $7.4 million were in the Asia Pacific
region.
 
     The Company 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. The Company 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.
 
DISTRIBUTION
 
     The Company sells its products primarily through a direct sales force. The
Company has sales and service offices throughout North America, Europe, the Asia
Pacific region, and Japan.
 
COMPETITION
 
     The Company faces substantial competition throughout the world, primarily
from electronic test systems manufacturers located in the United States, Europe,
and Japan, as well as several of the Company's customers. Some of these
competitors have substantially greater financial and other resources with which
to pursue engineering, manufacturing, marketing, and distribution of their
products. New product introductions by the Company's competitors could cause a
decline in sales or loss of market acceptance of existing products.
 
                                    BACKLOG
 
     On December 31, 1996, the Company's backlog of unfilled orders for
electronic test systems and backplane connection systems was approximately
$433.9 million and $82.5 million, respectively, compared with $607.1 million and
$52.2 million, respectively, on December 31, 1995. Of the backlog at December
31, 1996, approximately 82% of the electronic test systems backlog, and
approximately 91% of the backplane connection systems backlog are expected to be
delivered in 1997. The electronic test systems backlog at December 31, 1996
includes $36.1 million of United States government orders for M900 VXI Digital
Test subsystems for the U.S. Navy's Consolidated Automated Support System (CASS)
which are unfunded. The unfunded orders are for shipments scheduled to be
delivered in 1997 and beyond. The Company's past
 
                                        2
   4
 
experience indicates that a portion of orders included in the backlog may be
canceled. There are no seasonal factors related to the backlog.
 
                                 RAW MATERIALS
 
     The Company's products require a wide variety of electronic and mechanical
components. In the past, the Company has experienced occasional delays in
obtaining timely delivery of certain items. Additionally, the Company could
experience a temporary adverse impact if any of its sole source suppliers ceased
to deliver products. Any prolonged inability of the Company to obtain adequate
yields or deliveries, or any other circumstances that would require the Company
to seek alternative sources of supply could have a material adverse effect on
the Company's business, financial condition, and results of operations.
 
                              PATENTS AND LICENSES
 
     The development of products by the Company, both hardware and software, is
largely based on proprietary information. The Company protects its rights in
proprietary information through various methods such as copyrights, trademarks,
patents and patent applications, software license agreements, and employee
agreements. The Company relies on certain intellectual property protections to
preserve its intellectual property rights. Any invalidation of the Company's
intellectual property rights could have a material adverse effect on the
Company's business.
 
                                   EMPLOYEES
 
     As of December 31, 1996, the Company employed approximately 5,000 people.
Since the inception of the Company's business, there have been no work stoppages
or other labor disturbances. The Company has no collective bargaining contracts.
 
                     ENGINEERING AND DEVELOPMENT ACTIVITIES
 
     The highly technical nature of the Company's products requires a large and
continuing engineering and development effort. Engineering and development
expenditures for new and improved products were approximately $143.9 million in
1996, $123.5 million in 1995, and $86.6 million in 1994. These expenditures
amounted to approximately 12% of consolidated net sales in 1996, 10% in 1995,
and 11% in 1994.
 
                             ENVIRONMENTAL AFFAIRS
 
     The Company's manufacturing facilities are subject to numerous laws and
regulations designed to protect the environment, particularly from manufacturing
plant wastes and emissions. These include laws such as the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, 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 has not had and is currently not expected to have a material
adverse effect upon the financial position of the Company.

     The number of record holders of the Company's Common Stock at February 21,
1997 was 3,757.
 
     The Company 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 the Company's earnings, capital requirements, and financial
condition. The Company presently expects to retain all of its earnings for use
in the business.

RESULTS OF OPERATIONS:
 
  1996 compared to 1995
 
     In 1996, sales declined 2% to $1,171.6 million from the record level of
$1,191.0 million reached after 53% sales growth in 1995. The decrease was
primarily in the semiconductor test systems product line, which fell 8% as a
result of a reduction in orders from semiconductor device manufacturers. Sales
of telecommunications test systems also declined by 4% with the completion of
the line-test equipment installation at Deutsche Telekom in Germany. Sales
increased in the other two major product lines of the Company: circuit-board
test systems grew by 19% driven by fulfilling government contracts and increased
sales to commercial customers and backplane connection systems grew by 15% with
strong demand from the high technology commercial customer base. Net income
decreased from $159.3 million in 1995 to $93.6 million in 1996. Excluding the
effect of pre-tax nonrecurring charges of $48.9 million ($32.0 million after
taxes) in 1996 and $5.6 million ($5.6 million after taxes) in 1995, comparative
net income decreased by $39.3 million from $164.9 million to $125.6 million.
 
     Incoming orders decreased 27%, from $1,432.1 million in 1995 to $1,045.1
million in 1996. The most significant decline was in semiconductor test systems
orders which fell 37%. Circuit-board test systems orders, excluding the effect
of $98.0 million in multi-year government contracts received in 1995, were down
8% while backplane connection systems and telecommunications systems increased
49% and 21%, respectively. As a result of the overall decrease in orders, the
Company's backlog fell in 1996, finishing the year at $516.4 million (as
adjusted for $16.4 million in cancellations).
 
                                        7
   9
 
     Cost of sales, as a percentage of sales, increased from 54% in 1995 to 62%
in 1996. The 1996 cost of sales included $34.1 million in one time charges
resulting from the Company's decision to accelerate the consolidation of the
VLSI product lines of Megatest and Teradyne. Excluding the product line
consolidation charge, cost of sales, as a percentage of 1996 sales, was 59%. The
remaining increase in cost of sales percentage was the result of the
relationship of fixed manufacturing costs and the costs associated with new
product introductions to the lower level of sales. In addition, there was an
unfavorable change in mix as a greater percentage of total Company sales were
backplane connection systems and circuit-board test systems whose product
margins are generally lower than semiconductor test systems.
 
     Engineering and development expenses, as a percentage of sales, increased
2% from 10% in 1995 to 12% in 1996. These expenses grew $20.4 million in 1996
primarily as a result of increased investment in new product development of
semiconductor test systems. During 1996, the Company announced major new
products in each of the three semiconductor markets in which it participates.
 
     Selling and administrative expenses were 15% of sales in 1996 and 1995. In
1996, the Company provided $10.8 million for salary continuation payments and
enhanced pension and medical benefits associated with an early retirement
program and other workforce reductions. Excluding this provision selling and
administrative expenses were 14% of sales in 1996.
 
     Interest income increased 36% in 1996 to $19.3 million due to an increase
in the Company's average invested balances and higher interest rates. Interest
expense decreased from $3.0 million in 1995 to $2.4 million in 1996 as an
outstanding capital equipment note was paid.
 
     The Company's effective tax rate was 33% in 1996 compared with 36% in 1995.
The Company utilized domestic export sales corporation benefits and certain
research and development tax credits in 1996 to operate below the U. S.
statutory rate of 35%. In 1995, the effective rate was above the U. S. statutory
rate as certain merger expenses were nondeductible for income tax purposes.
 
  1995 compared to 1994
 
     Sales advanced 53% in 1995 to $1,191.0 million. Each of the major product
lines of the Company -- semiconductor test systems, circuit-board test systems,
telecommunications test systems, and backplane connection systems contributed to
the increase in sales. Sales of semiconductor test systems grew 70% as
semiconductor manufacturers continued to add capacity in response to rising
demand for their products. This capacity expansion was evidenced by a number of
new semiconductor manufacturing plants coming on line. Telecommunications test
systems sales increased 84% primarily from the growing installation of line-test
equipment at Deutsche Telekom in Germany. Sales of backplane connection systems
increased 18% as a result of greater penetration into the Company's high
technology commercial customer base. Circuit-board test systems sales increased
13%. As a result of the increase in sales, net income more than doubled in 1995,
increasing $82.9 million to $159.3 million.
 
     Incoming orders grew faster than sales in 1995, increasing 59% to $1,432.1
million. The increase in orders, like the increase in sales, was primarily due
to increases in semiconductor test systems orders, which increased 73%.
Additionally, circuit-board test systems orders increased by 110% due in large
part to multi-year U.S. government contracts, totaling $98.0 million, to supply
electronic test equipment for the B-2 Stealth Bomber and for the Navy's CASS
program. Orders for backplane connection systems and telecommunications test
systems declined 11% and 5%, respectively. As a result of the overall increase
in orders, the Company's backlog grew 58% in 1995, finishing the year at $659.3
million.
 
     Cost of sales, as a percentage of sales, decreased from 56% in 1994 to 54%
in 1995. The improvement was primarily the result of increased utilization of
the fixed and semi-variable components of the Company's overhead structure. In
addition, there was a favorable change in mix as sales of backplane connection
systems and circuit-board test systems, whose product margins are generally
lower than those of semiconductor test systems, were lower as a percentage of
total Company sales.
 
     Engineering and development expenses, as a percentage of sales, declined 1%
from 11% in 1994 to 10% in 1995, as these expenses did not increase at the same
rate as sales. The dollar amount of these expenses grew
 
                                        8
   10
 
$36.9 million in 1995 as a result of increased investment in new product
development of semiconductor test systems. Selling and administrative expenses
decreased to 15% of sales in 1995 compared with 19% of sales in 1994, as the
dollar volume of these expenses grew by 19% while sales increased 53%.
 
     Interest income increased 82% in 1995 to $14.2 million due to an increase
in the Company's average invested balances and higher interest rates. Interest
expense increased from $1.8 million in 1994 to $3.0 million in 1995 as a result
of increased borrowing at Megatest prior to the merger.
 
     The Company's effective tax rate was 36% in 1995 compared with 33% in 1994.
The Company utilized certain tax credit and operating loss carryforward amounts
in 1994 to operate below the United States statutory rate of 35%. In 1995, the
effective rate increased as the tax credit and operating loss carryforwards were
no longer available and certain merger expenses were nondeductible for income
tax purposes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's cash, cash equivalents and marketable securities balance grew
$155.7 million in 1996, to $431.5 million following an increase of $54.6 million
in 1995. Cash flow generated from operations was $250.8 million in 1996 and
$115.5 million in 1995. Cash of $13.5 million in 1996 and $24.9 million in 1995
was generated from the sale of stock to employees under the Company's stock
option and stock purchase plans.
 
     Cash was used to fund additions to property, plant and equipment of $75.2
million in 1996 and $93.2 million in 1995. In 1996, the Company's Board of
Directors authorized the repurchase of 5.0 million shares of the Company's stock
on the open market. Cash of $29.8 million was utilized in 1996 to purchase 1.4
million shares under the buyback program.
 
     The Company believes its cash, cash equivalents, and marketable securities
balance of $431.5 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 in 1997.
 
     Inflation has not had a significant long-term impact on earnings. If there
were inflation, the Company's efforts to cover cost increases with price
increases could be frustrated in the short-term by its relatively high backlog.
 
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-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 1: Business" relating to the Company'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 expenditure, and stock
repurchase 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 contributed to
a 37% decline in semiconductor test system orders. There can be no assurance
that any future increase in semiconductor test systems bookings for a calendar
quarter will be sustained in subsequent
 
                                        9
   11
 
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.
 
     Also, the Company relies on certain intellectual property protections to
preserve its intellectual property rights. From time to time the Company is
notified that it may be in violation of patents held by others. Any invalidation
of the Company's intellectual property rights, or assertions of patent
infringement against the Company which are ultimately successful, could have a
material adverse effect on the Company. Lengthy and expensive defense of the
Company's rights to technology used in its products 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 new product
selection, 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 faces substantial competition throughout the world, primarily
from electronic test systems manufacturers located in the United States, Europe
and Japan, as well as several of the Company's customers. Some of these
competitors have substantially greater financial and other resources which to
pursue engineering, manufacturing, marketing and distribution of their products.
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 revenues 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 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; the timing and provision of pricing
protections and returns from certain distributors; 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. 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.

December 31, 1996 and 1995, and the related consolidated statements of income,
cash flows, and changes in shareholders' equity for each of the three years in
the period ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits. We did not audit the
consolidated financial statements of Megatest for the year ended August 31,
1994, which statements reflect consolidated net sales constituting 13% of the
related consolidated net sales for the year ended December 31, 1994. Those
statements were audited by other auditors whose report has been furnished to us,
and our opinion, insofar as it relates to the amounts included for Megatest, is
based solely on the report of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of the other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the report of the other auditors,
the financial statements referred to above present fairly, in all material
respects, the consolidated financial position of Teradyne, Inc. as of December
31, 1996 and 1995, and the consolidated results of its operations and its cash
flows for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
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 are
eliminated. Certain prior years' amounts were reclassified to conform to the
current year presentation. On December 1, 1995, the Company completed its
acquisition of Megatest Corporation ("Megatest"), by means of a merger accounted
for as a pooling of interests. As a result of the merger, Megatest became a
wholly owned subsidiary of the Company. The consolidated financial statements of
the Company for periods prior to the merger were restated to include the
financial position and results of operations of the combined companies.
 
  Preparation of Financial Statements
 
     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.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out basis) or
market (net realizable value).
 
  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.
 
     The Company 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Revenue Recognition
 
     Revenue is recorded when products are shipped or, in instances where
products are configured to customer requirements, upon the successful completion
of test procedures. Service revenue is recognized ratably over applicable
contract periods or as services are performed. In certain situations, revenue is
recorded using the percentage of completion method based upon the completion of
measurable milestones, with changes to total estimated costs and anticipated
losses, if any, recognized in the period in which determined.
 
  Engineering and Development Costs
 
     The Company'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.
 
  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.
 
     The Company's practice is to provide U.S. Federal taxes on undistributed
earnings of the Company's non U.S. sales and service subsidiaries.
 
  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
 
     Net income per common share is based upon the weighted average number of
common and common equivalent shares outstanding (when dilutive) each year.
Common equivalent shares result from the assumed exercise of outstanding stock
options, the proceeds of which are then assumed to have been used to repurchase
outstanding common stock using the treasury stock method. Primary and fully
diluted earnings per share are equal for all periods presented.
 
C. MERGER -- POOLING OF INTERESTS
 
     On December 1, 1995, the Company acquired through a merger all of the
authorized and outstanding common stock of Megatest in exchange for
approximately 6.8 million shares of the Company's common stock using an exchange
ratio of 0.9091 of one share of the Company's common stock for each Megatest
share. In addition, all outstanding Megatest stock options were converted, at
the common stock exchange ratio, into options to purchase the Company's common
stock. Megatest manufactures electronic test systems for the integrated circuit
industry. Prior to the merger, Megatest prepared its financial statements on an
August 31 fiscal year end. Megatest's fiscal year has been changed to December
31 to conform to the Company's year end. The restated financial statements for
1994 include Megatest's amounts as of and for the year ended August 31, 1994. As
a result, Megatest's corresponding results of operations and cash flows as of
and for the four month period ended December 31, 1994 are not reflected in the
Company's consolidated statements of

income and cash flows. Megatest's loss for this period of $14.8 million has been
charged to retained earnings effective January 1, 1995. Megatest's results of
operations for the four months ended December 31, 1994 are summarized as follows

     The combined financial results reflect the restatement of Megatest's
provision for income taxes in accordance with Statement of Financial Accounting
Standards No. 109 Accounting for Income Taxes. Due to the merger, Megatest's
previously unrecognized tax benefits of deductible temporary differences and
operating loss carryforwards were recognized by the combined company in the
restated periods. The restatement of the provision for income taxes decreased
net income in 1994 by $5.1 million. The combined financial results also include
adjustments, which were immaterial to the combined financial statements, to
conform accounting policies of the two companies. Adjustments made to conform
the accounting policies of the two companies decreased net income by $0.2
million in 1995 and 1994. All other adjustments consist of reclassifications to
conform financial statement presentation. There were no intercompany
transactions between the two companies for the periods presented. In connection
with the merger, the Company recorded a $5.6 million nonrecurring charge for
transaction costs consisting primarily of professional fees.
 
D. FINANCIAL INSTRUMENTS
 
  Cash Equivalents
 
     The Company considers all highly liquid investments with original
maturities of three months or less at date of acquisition to be cash
equivalents.
 
  Marketable Securities
 
     The Company classifies investments in marketable securities as trading,
available-for-sale or held-to-maturity at the time of purchase and periodically
re-evaluates such classification. There were no securities classified as trading
as of December 31, 1996 or 1995. Securities are classified as held-to-maturity
when the Company has the positive intent and ability to hold the 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 not classified as held-to-maturity are classified as
available-for-sale and reported at fair market value. Unrealized gains or losses
on available-for-sale securities, if material, are included, net of tax, in
shareholders equity until disposition. Realized gains and losses and declines in
value 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 five years. At December 31, 1996 and 1995 these investments
are reported as follows (in thousands):

  Other
 
     For all other balance sheet financial instruments the carrying amount
approximates fair value.
 
  Off-Balance Sheet Risk
 
     The Company regularly enters into forward contracts in European and
Japanese currencies to hedge its overseas net monetary position and firm
commitments. These contracts are used to reduce the Company'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. The
Company does not engage in currency speculation. Forward currency contracts have
maturities of less than one year, unless they relate to long term sales
contracts denominated in a non U.S. currency; these maturities are from one to
three years.
 
     At December 31, 1996, the Company had the following forward currency
contracts to buy U.S. dollars for non U.S. currencies with notional amounts
totaling $48.8 million: $15.8 million Japanese yen, $14.0 million German
deutschemark, $8.7 million British pound sterling, and $10.3 million various
other European currencies. In addition, the Company had forward currency
contracts to sell U.S. dollars for German deutschemarks with notional amounts of
$11.2 million. At December 31, 1995 the face amount of outstanding forward
currency contracts to buy and sell U.S. dollars for non U.S. currencies was
$66.3 million and $22.9 million, respectively.
 
     The fair value of these contracts as of December 31, 1996 and 1995,
determined by applying year end currency exchange rates to the notional contract
amounts, represented a net unrealized gain (loss) of $0.1 million and $(4.4)
million, respectively. The Company's policy is to defer gains and losses on
these contracts until the corresponding losses and gains are recognized on the
items being hedged. At December 31, 1995, a net $1.0 million loss was included
in other current assets. The entire net loss was recognized during 1996 to
offset currency transaction gains on hedged items.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Company to

corporate debt securities, rated A1 or higher, which have minimal credit risk.

     In addition to the above plans, the Company has an unfunded supplemental
defined benefit pension plan in the United States to provide retirement benefits
in excess of levels allowed by the Employee Retirement Income Security Act
(ERISA). The actuarial present value of accumulated plan benefits totaled $2.7
million and $1.9 million at December 31, 1996 and 1995, respectively. Net
pension expense was $0.7 million, $0.5 million, and $0.4 million in 1996, 1995,
and 1994, respectively.
 
     In 1996, the Company announced a voluntary early retirement incentive
program to certain employees. The special termination benefits include enhanced
pension benefits to the employees and medical and dental benefits to the
employees and their spouses. Pension benefits of $2.6 million to be paid from
the Company's existing pension plans were accrued at December 31, 1996 relating
to this program. In addition, the Company accrued $2.5 million for
postretirement medical and dental benefits.
 
H. STOCK REPURCHASE PROGRAM
 
     During August 1996, the Company's Board of Directors authorized the
purchase in the open market of up to 5.0 million shares of its common stock to
offset shares issued under the Company's stock based compensation plans. During
1996, the Company repurchased 1.4 million shares at a cost of $29.8 million.
 
I. STOCK BASED COMPENSATION
 
     At December 31, 1996, the Company had both stock option plans and Stock
Purchase Plans. The Company applies APB Opinion 25 and related interpretations
in accounting for its plans. Under APB Opinion 25, no compensation cost has been
recognized. Statement of Financial Accounting Standards (SFAS) No. 123 requires
companies to disclose pro forma net income and earnings per share amounts under
the new fair value method. The effects of applying SFAS No. 123 in this pro
forma disclosure are not indicative of future amounts. SFAS No. 123 does not
apply to awards made prior to 1995. Additional awards

in future years are anticipated. Had compensation cost for the Company's stock
based compensation plans been determined based on the fair value at the grant
dates for awards under those plans consistent with SFAS No. 123, the Company's
net income and earnings per share would have been reduced to the pro forma
amounts indicated below (in thousands, except per share amounts):

     The weighted average fair value at date of grant for options granted during
1996 and 1995 was $4.79 and $8.69 per option, respectively. The fair value of

  Employee Stock Purchase Plans
 
     Under the Company's 1979 Stock Purchase Plan, employees were entitled to
purchase shares of common stock through payroll deductions of up to 10% of their
compensation. The price paid for the common stock was equal to 85% of the lower
of the fair market value of the Company's common stock on either the first or
last business day of the year. In January 1997, the Company issued 506,820
shares of common stock to employees who participated in the Plan during 1996 at
a price of $20.82 per share. No future shares will be issued under this plan.
 
     During 1996, the Company adopted the 1996 Employee Stock Purchase Plan and
authorized 700,000 shares for future issuance. 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 the Company's common stock on the
first business day in January (July for new hires) or the last business day of
December. In January 1997, the Company issued 15,557 shares of common stock to
employees who participated in the plan during 1996 at a price of $15.09 per
share. Currently, there are 684,443 shares reserved for issuance.
 
     The weighted-average fair value of purchase rights granted in 1996 and 1995
was $5.22 and $3.07, respectively. The fair value of the employees' purchase
rights was estimated using the Black-Scholes model with the following
assumptions for 1996 and 1995, respectively; dividend yield of 0.0% for both
years; an expected life of 1 year for both years; expected volatility of 44.7%
and 38.8%; and risk-free interest rates of 5.2% and 7.1%.
 
J. SAVINGS PLANS
 
     The Company sponsors a Savings Plan covering substantially all U.S.
employees. Under this plan, employees may contribute up to 12% of their
compensation (subject to Internal Revenue Service limitations). The Company
annually matches employee contributions up to 6% of such compensation at rates
ranging from

50% to 100%. The Company's contributions vest after two years, although
contributions for those employees with five years of service vest immediately.
 
     The trustees of the Savings Plan were granted an option to purchase 0.9
million shares of the Company's common stock, exercisable at $9.50 per share
(the fair market value of the Company's common stock at the date of the grant)
in five cumulative annual installments beginning in 1990. In 1994, the trustees
exercised the remaining shares. Under the terms of the Plan, any gains realized
from the sale of option shares were first allocated to participants' accounts to
fund up to one-half of the minimum Company contribution. Any excess was applied
to additional funding.
 
     In 1994, the Company established a Supplemental Savings Plan to provide
savings benefits in excess of those allowed by ERISA. The provisions of which
are the same as the Savings Plan.
 
     Under these plans, the amounts charged to operations were $6.3 million in
1996, $8.3 million in 1995, and $2.0 million in 1994.
 
K. STOCKHOLDER RIGHTS PLAN
 
     The Company's Board of Directors adopted a Stockholder Rights Plan on March
14, 1990, 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 the Company's common stock for $20
per share in certain events, such as a tender offer to acquire 30% or more of
the Company's outstanding shares. Under some circumstances, such as a
determination by continuing Directors, that an acquiring party's interests are
adverse to those of the Company, the Plan entitles such holders (other than an
acquiring party or adverse party) to purchase $40 worth of Common Stock (or
other securities or consideration owned by the Company) for $20. The Rights will
expire March 26, 2000 unless earlier redeemed by the Company.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
     In our opinion, the consolidated balance sheet and related consolidated
statements of operations, of stockholders' equity and of cash flows of Megatest
Corporation (not presented separately herein) present fairly, in all material
respects, the financial position of Megatest Corporation and its subsidiaries at
August 31, 1994, and the results of their operations and their cash flows for
the year ended August 31, 1994, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audit. We conducted our audit of these statements in
accordance with generally accepted auditing standards 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 audit provides a reasonable basis for the opinion expressed
above.
 
     As discussed in Note 1 to the consolidated financial statements referred to
above (and not included herein), Megatest Corporation changed its method of
accounting for income taxes effective September 1, 1993.
