                                   FORM 10-K
 

                                     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 L:
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.
 
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
incoming inspection of components and 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 systems produced by the Company include: (i) test systems for a
wide variety of semiconductors, including digital and analog integrated
circuits, (ii) test systems for circuit boards and other assemblies, and (iii)
test systems for telephone lines and networks. 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.
 
     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, telecom-munications, 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. The Company has begun
to evolve the manufacture of backplane connection systems to the manufacture of
fully integrated electronic assemblies that include backplane, card cage,
cabling, and related design and production services.

                              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. The Company believes that it could suffer the loss of one or even a
few major customers without serious long-term adverse effects. Sales to
Motorola, Inc. were $69.3 million in 1993, which were greater than 10% of the
Company's net sales in 1993. No other customer accounted for more than 10% of
net sales in 1993.
 
     Direct sales to United States Government agencies accounted for
approximately 2% of net sales in 1993 and 1992, and 1% in 1991. In addition,
sales are made, within each of the Company's segments, to customers who are
government contractors. Approximately 33% of all backplane connection systems
sales and less than 10% of all electronic test systems sales fell into this
category during 1993.
 
     The Company's overseas customers are located primarily in Europe, Asia
Pacific, and Japan. Sales to overseas customers consist principally of
electronic test systems, and these sales occur either through foreign sales
subsidiaries or through direct exports. Substantially all of the Company's
manufacturing activities are conducted in the United States.
 
     Sales to overseas customers accounted for 41% of net sales in 1993, 42% in
1992, and 47% in 1991. Identifiable assets of the Company's foreign
subsidiaries, consisting principally of accounts receivable and other operating
assets, approximated $65.0 million at December 31, 1993, $86.0 million at
December 31, 1992, and $82.0 million at December 31, 1991. Of these identifiable
assets at December 31, 1993, $39.0 million were in Europe, $23.0 million were in
Japan, and $3.0 million were in Asia Pacific. Since sales to overseas customers
have little correlation with the location of manufacture, it is not meaningful
to present operating profit by geographic area.
 
     The Company is subject to the inherent risks involved in international
trade, such as political instability, restrictive trade policies, controls on
funds transfer, and foreign currency fluctuations. The Company attempts to
reduce the effects of currency fluctuations by hedging part of its exposed
position and by conducting some of its foreign transactions in U.S. dollars or
dollar equivalents.
 
DISTRIBUTION
 
     The Company sells its electronic systems primarily through a direct sales
force. Backplane connection systems are sold by direct sales personnel as well
as by manufacturers' representatives. The Company has sales and service offices
throughout North America, Europe, Asia Pacific, and Japan.
 
COMPETITION
 
     Competition is intense in each of the business areas that the Company
operates. In each market there are several significant competitors (three to
five). Many of these competitors have greater resources than the Company.
Competition is principally based on technical performance, equipment and service
reliability, reputation and accessibility to the vendor, and price. While
relative positions vary from year to year, the Company believes that it operates
with a significant market share position in each of its businesses.
 
                                    BACKLOG
 
     On December 31, 1993, the Company's backlog of unfilled orders for
electronic test systems and backplane connection systems was approximately
$238.9 million and $49.1 million, respectively, compared with $183.0 million and
$34.8 million, respectively, on December 31, 1992. Of the backlog at December
31, 1993, approximately 75% of the electronic test systems backlog, and
substantially all of the backplane connection systems backlog is expected to be
delivered in 1994, although the Company's past experience indicates that a
portion of orders included in the backlog may be cancelled. There are no
seasonal or unusual 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. Management believes, however, that alternate sources could
be developed.
 
                              PATENTS AND LICENSES
 
     The development of products by the Company, both hardware and software, is
largely based on proprietary information. The various copyrights, trademarks,
and patents owned by the Company, together with patent applications pending, are
generally not significant in relation to the Company's overall business.
However, protection of such proprietary information, through methods such as
patents, software license agreements with customers and employee agreements, is
important for certain of the Company's products. The Company does not hesitate
to assert its rights to intellectual property when, in its view, these rights
are infringed upon. Also from time to time, claims have been asserted that
certain of its products and technologies infringe the patent rights of third
parties. In the opinion of management, none of these claims are expected to have
a material effect on the consolidated financial or competitive position of the
Company.
 
                                   EMPLOYEES
 
     As of December 31, 1993, the Company employed approximately 4,000 persons.
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 $62.4 million in
1993, and $62.0 million in 1992 and 1991. These expenditures amounted to
approximately 11% of net sales in 1993, and 12% in 1992 and 1991.
 
                             ENVIRONMENTAL AFFAIRS
 
     The Company's manufacturing facilities are subject to numerous laws and
regulations designed to protect the environment, particularly from plant wastes
and emissions. These include laws such as the Comprehensive Environmental
Response, Compensation and Liability Act of 1980 ("CERCLA"), the Occupational
Safety and Health Act, the Clean Air Act, the Clean Water Act, the Hazardous and
Solid Waste Amendments of 1984 and Resource Conservation and Recovery Act of
1976. In the opinion of management, compliance with these laws and regulations
has not had and will not have a material effect upon the capital expenditures,
earnings and competitive position of the Company.

     The number of record holders of the Company's Common Stock at February 25,
1994 was 3,225.
 
     The Company has never paid cash dividends because it has been its policy to
use earnings to finance expansion and growth. While payment of future 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.

</TABLE>

 
RESULTS OF OPERATIONS:
 
  1993 Compared to 1992
 
     Sales increased 5% in 1993, to $554.7 million. The increase in sales was
primarily due to a 13% increase in sales of semiconductor test systems and, to a
lesser extent, a 7% increase in sales of backplane connection systems. Sales of
semiconductor test systems increased as semiconductor manufacturers added
capacity in response to rising demand for their products. Sales of circuit-board
test systems and telecommunications systems declined 7% and 18%, respectively,
in 1993 compared to 1992. Incoming orders increased 19% in 1993 to $625.0
million over 1992 with increased orders occurring in each of the Company's major
groups. The Company's backlog grew during 1993 to $288.0 million.
 
     Income before taxes increased by $25.3 million from 1992 to 1993 on a sales
increase of $25.2 million as the Company continued to control the growth in its
operating expenses. In addition, costs in 1993 were lower in the Company's
circuit-board test operations following actions taken by the Company in 1992 to
consolidate those operations. These lower costs helped to offset the impact of
the reduced sales of circuit-board test systems.
 
     Cost of sales decreased from 59% of sales in 1992 to 57% in 1993. While
sales increased in 1993, the fixed and semi-variable components of cost of sales
decreased as a result of the Company's cost reduction programs. The changes in
engineering and development expenses and selling and administrative expenses
were each less than 1% in 1993, compared to 1992. These expenses have
essentially remained at their current level since 1991, as the Company has
controlled the growth of its fixed costs.
 
                                        7

<PAGE>   9
 
     Interest income increased 44% in 1993 as a result of a $76.2 million
increase in the Company's cash and cash equivalents balance during the year.
Interest expense decreased 12% in 1993 primarily as a result of the Company's
retirement of its 9.25% outstanding convertible subordinated debentures in the
fourth quarter.
 
     The Company's effective tax rate increased from 13.5% in 1992 to 30% in
1993. The Company had been able to utilize net operating loss carryforwards to
lower its United States taxable income for financial reporting purposes in 1992,
while in 1993 those carryforwards were no longer available. However, the
Company's tax rate in 1993 was below the United States statutory rate of 35%, as
a result of the utilization of tax credit carryforwards and foreign net
operating loss carryforwards. There continue to be tax credit carryforwards and
foreign net operating loss carryforward amounts which will lower the Company's
prospective tax rate if utilized. The Company adopted Statement of Financial
Accounting Standards No. 109 "Accounting for Income Taxes" at the beginning of
1993. The effect of this change in accounting principle was not material to the
Company's consolidated financial position. See "Note K: Income Taxes" in Notes
to Consolidated Financial Statements.
 
     In connection with the retirement of the Company's outstanding 9.25%
convertible subordinated debentures, the Company incurred, in the fourth quarter
of 1993, an extraordinary charge of $0.7 million, net of income taxes, for the
costs of the redemption premium of 3.7% and the write off of unamortized debt
issuance costs.
 
  1992 Compared to 1991
 
     Sales increased 4% in 1992, to $529.6 million. The sales increase was
primarily due to a 13% increase in sales of semiconductor test systems over 1991
and, to a lesser extent, a 7% increase in sales of connection systems.
Offsetting the increased sales were reduced sales of circuit-board test systems
and telecommunications systems which were down 12% and 5%, respectively. The
Company believes that the over-all market for semiconductor test systems
declined in 1992 and that, the increase in sales represents market-share growth.
The decline in sales of circuit-board test systems was primarily due to a
decrease in demand from U.S. government defense contractors.
 
     During the year, the Company decided to concentrate its efforts in
Electronic Design Automation (EDA) on software products for test generation and
design verification. This decision led to the closing of the EDA operation in
Santa Clara, California and the consolidation of the EDA operation in Boston,
Massachusetts with the circuit-board test division. The Company also decided to
move the circuit-board assembly operation in Walnut Creek, California to the
central circuit-board assembly operation in Boston.
 
     Cost of sales increased as a percent of sales from 58% to 59%. This
increase was due to the fact that, while the Company reduced its overhead
associated with circuit-board test systems and telecommunications systems, it
did not reduce such expenses proportionately with the reduction in sales of
these two product lines.
 
     Engineering and development expenses were essentially unchanged in 1992,
while the amount of selling and administrative expenses increased less than 1%
as the Company controlled the growth of these expenses.
 
     Interest income increased 78% in 1992 to $2.5 million due to an increase in
the Company's cash and cash equivalents balance beginning in the second half of
1991. Cash had grown by $63.8 million from June 29, 1991 to December 31, 1992.
Interest expense decreased 21% in 1992 due to a reduction in the average level
of debt outstanding during the year and lower average short-term interest rates.
 
     The Company's effective tax rate increased from 10% in 1991 to 13.5% in
1992. At the end of 1992, the Company had utilized all of its available U.S.
Federal net operating loss carryforwards for financial reporting purposes.

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's cash balance increased by $76.2 million in 1993, following an
increase of $32.0 million in 1992. Cash flow generated from operations was $91.8
million in 1993 and $40.7 million in 1992. Additional cash of $33.6 million in
1993 and $15.7 million in 1992 was generated from the sale of stock to employees
under the Company's stock option and stock purchase plans. In 1992, cash of $3.2
million was also raised from a bank note to finance future construction of a
plant in Kumamoto, Japan.
 
     Cash was used to fund additions to property, plant and equipment of $32.2
million in 1993 and $28.2 million in 1992. The Company also used $14.7 million
of its cash to retire outstanding debt and $2.3 million to purchase stock from
its shareholders pursuant to the Company's open market stock repurchase program.
The debt retirement included $10.8 million for the repurchase of the outstanding
convertible debentures and a cash payment of $3.2 million for the exercise of a
purchase option on the Company's headquarters building in Boston, Massachusetts.
 
     The Company believes its cash and cash equivalents balance of $143.6
million, together with other sources of funds, including cash flow generated
from operations and available borrowing capacity of $80.0 million under its line
of credit agreement, will be sufficient to meet future working capital and
capital expenditure requirements.
 
     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 would be frustrated in the short term by its relatively high backlog.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
A. ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of Teradyne,
Inc. and its subsidiaries, all of which are wholly owned (referred to
collectively in these notes as the "Company"). All significant intercompany
balances and transactions have been eliminated. Certain prior years' amounts
have been reclassified to conform to the current year presentation.
 
  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 eliminated from the accounts and any
resulting gain or loss is reflected in operations.
 
     The Company provides for depreciation of its property principally on the
straight-line method by charges to expense which are sufficient to write off the
cost of the assets over their estimated useful lives.
 
  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
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes." This
statement superseded the previous accounting standard for income taxes, SFAS 96,
which the Company adopted January 1, 1991. The adoption of SFAS 109 had no
material effect on the results of operations.
 
     Under SFAS 109, 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.
 
     In general, the Company's practice is to provide U.S. federal taxes on
undistributed earnings of the Company's foreign sales and service subsidiaries.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
A. ACCOUNTING POLICIES -- (CONTINUED)

  Translation of Foreign Currencies
 
     Assets and liabilities of foreign subsidiaries which are denominated in
foreign currencies have been remeasured into U.S. dollars at rates of exchange
in effect at the end of the fiscal year except fixed assets which have been
remeasured using historical exchange rates. Revenue and expense accounts have
been remeasured using an average of exchange rates in effect during the year.
Net realized and unrealized gains and losses resulting from foreign currency
remeasurement are included in operations.
 
  Financial Instruments and Related Disclosures
 
     Financial instruments consist primarily of investments in cash, cash
equivalents and accounts receivables and obligations under accounts payable and
debt instruments. Fair value of financial instruments have been determined
through information obtained from market sources and management estimates. At
December 31, 1993, the fair value of the Company's financial instruments
approximates the carrying value.
 
     The Company enters into foreign exchange contracts to hedge assets,
liabilities, and transactions denominated in foreign currencies on a continuing
basis for periods consistent with its committed exposures. The foreign exchange
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 foreign
exchange gains and losses on the assets, liabilities, and transactions being
hedged. As of December 31, 1993, the Company had $51.9 million of foreign
exchange contracts outstanding, $40.0 million of which were in German marks,
$11.0 million in various other European currencies, and $0.9 million in Japanese
yen. The German mark contracts have maturities of one to three years. The
Company's other foreign exchange contracts generally have maturities which do
not exceed six months. All of the foreign exchange contracts require the Company
to exchange foreign currencies for U.S. dollars at maturity, at rates agreed to
at inception of the contracts.
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents and trade
receivables. The Company places its cash equivalents in high grade financial
instruments and, by policy, limits the amount of credit exposure to any one
financial institution. Concentrations of credit risk with respect to trade
receivables are limited due to the large number of diverse and geographically
dispersed customers.
 
  Net Income Per Common Share
 
     Net income per common share is based upon the weighted average number of
common and common equivalent shares (when dilutive) outstanding 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 at the average market price during the year.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
B. CASH AND CASH EQUIVALENTS
 
     Cash equivalents consist of short-term investments in money market
instruments with an original maturity of three months or less. These amounts are
carried at cost plus accrued interest, which approximates market value. Of the
$143.6 million cash and cash equivalents balance at December 31, 1993, cash
equivalents amounted to $125.3 million, which included $112.5 million of U.S.
Treasury bills. Of the $67.4 million cash and cash equivalents balance at
December 31, 1992, cash equivalents amounted to $58.8 million, which included
$50.8 million of U.S. Treasury bills.
 
C. LONG-TERM DEBT
 
     Long-term debt at December 31, 1993 and 1992 consisted of the following (in
thousands):

                                                                         ------     ------
</TABLE>

 
     The total maturities of long-term debt for each of the next five years are
$0.5 million.
 
  Revolving Credit Agreement
 
     The Company has $80.0 million of revolving credit available through January
31, 1996 under a domestic line of credit agreement with its banks. Under the
terms of the agreement, any amounts outstanding at December 31, 1996 are
converted into a one year term note. As of December 31, 1993, no amounts were
outstanding under this agreement. The terms of this line of credit also include
restrictive covenants regarding the working capital, tangible net worth and
leverage. Interest rates on borrowings are either at the stated prime rate or
based upon Eurocurrency or certificate of deposit interest rates. Additional
domestic and foreign borrowings up to $30.0 million are permitted outside the
agreement provided that the liabilities of the Company, exclusive of deferred
income taxes and subordinated debt, shall not exceed 100% of the Company's
tangible net worth.
 
  Mortgage Note Payable
 
     The Company has 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 the Company's property at 321
Harrison Avenue which may, at the Company's option, become subordinated to
another mortgage up to a maximum of $5.0 million. For the first 4 1/2 years of
the note, interest was accrued but not paid ("Accrued Interest"). Beginning
September 30, 1987, semi-annual interest payments are being paid on principal
and Accrued Interest. The principal and Accrued Interest are payable in full at
maturity.
 
  Industrial Revenue Bonds
 
     At December 31, 1993, the Company has outstanding industrial revenue bonds,
in the amount of $1.3 million, maturing in 1998 and 1999. These bonds are
payable in quarterly installments, including interest at the higher of 75% of
the stated prime rate or 7 1/2%. The bonds are collateralized by mortgage
interests on certain properties owned by the Company.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
C. LONG-TERM DEBT -- (CONTINUED)
  Capitalized Lease Obligations
 
     On December 31, 1993, the Company exercised its lease option to purchase
the property located at 321 Harrison Avenue, Boston, Massachusetts for $3.2
million.
 
  Other Long-term Debts
 
     At December 31, 1993, other long-term debt consists principally of a
Japanese yen-denominated note in the amount of $3.6 million at an interest rate
of 4.8%, secured by land in Kumamoto, Japan, with interest only payable until
March 31, 1995, and principal and interest payable in monthly installments from
April 29, 1995 to March 30, 2007.
 
D. CONVERTIBLE SUBORDINATED DEBENTURES
 
     At December 31, 1992, the Company had outstanding $15.4 million of 9.25%
convertible subordinated debentures due March 15, 2012. These debentures were
convertible into shares of the Company's common stock any time prior to maturity
at a conversion price of $23.50 per share. The amount shown on the Consolidated
Balance Sheets at December 31, 1992 was net of $1.0 million unamortized debt
issue costs.
 
     During 1993, $5.0 million principle amount of debentures were converted
into 210,585 shares of common stock resulting in an increase of $4.7 million of
shareholders' equity (net of the related $0.3 million unamortized debt issue
costs). On November 19, 1993, the Company exercised its option to repurchase the
remaining $10.4 million outstanding debentures. The Company used $10.8 million
of available cash from operations to repurchase the debentures at a premium of
103.7% of the principal amount. The premium amount and the writeoff of the
remaining unamortized debt issue cost resulted in a charge of $1.0 million. This
charge, net of the related taxes of $0.3 million, is reflected as an
extraordinary loss in the Consolidated Statements of Income.
 
E. COMMITMENTS
 
     Rental expense for the years ended December 31, 1993, 1992, and 1991 was
$11.2 million, $12.6 million, and $13.0 million, respectively. Minimum annual
rentals under all noncancellable leases are: 1994 -- $6.8 million; 1995 -- $5.5
million; 1996 -- $2.6 million; 1997 -- $1.1 million; 1998 -- $0.9 million; and
$6.3 million thereafter, totalling $23.2 million. Offsetting the future lease
payments, the Company's income from noncancellable subleases totals $1.2
million.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
F. PENSION PLANS
 
     The Company has defined benefit pension plans covering substantially all
domestic employees and employees of certain international subsidiaries. Benefits
under these plans are based on the employee's years of service and compensation.
The Company'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 the plans consist primarily of equity and fixed income securities.
 
     In 1993, the Company established a supplemental defined benefit pension
plan in the United States to provide retirement benefits in excess of levels
allowed by ERISA.
 
     In 1992, the Company established a defined benefit pension plan covering
its employees in Japan. The Company's foreign plans were not included in the
table below in 1991 because they were not significant in the aggregate. Net
pension expense for the domestic plans was $2.4 million in 1993, $1.8 million in
1992, and $1.5 million in 1991.
 
     The components of net pension expense are summarized as follows (in
thousands):

     The Company has recorded an additional minimum pension liability for
underfunded plans of $7.5 million at December 31, 1993, representing the excess
of unfunded accumulated benefit obligations over previously recorded pension
cost liabilities. A corresponding amount has been recognized as an intangible
asset to the extent of related unrecognized prior service cost of $5.2 million,
with the remaining amount of $1.5 million, net of taxes of $0.8 million,
recorded as a charge to stockholders' equity.

H. SAVINGS PLAN
 
     The Company sponsors a Savings Plan covering substantially all domestic
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 of 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 have been granted an option to purchase
900,000 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. The trustees exercised
335,000, 200,000, and 100,000 shares respectively in 1993, 1992, and 1991. Under
the terms of the Plan, any gains realized from the sale of option shares are
first allocated to participants' accounts to fund up to one-half of the minimum
Company contribution, with any excess applied to additional funding.
 
     Under this plan, the amounts charged to operations were $2.0 million in
1993 and 1992, and $1.8 million in 1991.
 
I. EMPLOYEE STOCK PURCHASE PLAN
 
     Under the 1979 Stock Purchase Plan, employees are entitled to 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 either the first or
last business day of the year. In January 1994, the Company issued 375,124
shares of common stock to employees who participated in the plan during 1993 at
a price of $12.82 per share. Currently there are 405,869 shares reserved for
issuance.
 
     There have been no charges to income in connection with this plan other
than incidental expenses related to the issuance of shares.
 
J. STOCKHOLDER RIGHTS PLAN
 
     The Company's Board of Directors adopted a Stockholder Rights Plan on March
14, 1990. Under the Plan, the Company distributed to stockholders a dividend of
one Common Stock Purchase Right for each outstanding share of Common Stock.
Initially, the Purchase Rights enable a stockholder to purchase one share of
Teradyne Common Stock for $40.00. Upon certain events, such as the initiation of
a tender offer for more than 30% of the Company's Common Stock, the Purchase
Rights allow stockholders to purchase $80.00 worth of Common Stock (or other
securities or consideration as determined by Continuing Directors of the
Company) for $40.00. Generally, at any time until 10 days following the
announcement that a person has acquired 20% of the outstanding shares of the
Company, the Company may redeem the Purchase Rights for $0.01 per share. The
Plan will expire March 26, 2000, unless earlier redeemed by the Company.
 
K. INCOME TAXES
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes." As
permitted by SFAS 109, the Company has elected not to restate its financial
statements for any periods prior to 1993. The effect on operations for 1993 was
immaterial. However, upon adoption of SFAS 109 the Company increased Additional
Paid-in Capital by $5.7 million relating to the tax benefits to be derived from
the utilization of U.S. net operating loss carryforward amounts resulting from
tax deductions pertaining to the issuance of the Company's stock to employees
under its benefit plans.

                                 TERADYNE, INC.

                        1991 EMPLOYEE STOCK OPTION PLAN

                   (Amended and Restated as of May 27, 1993)


     1.   Purpose.  This 1991 Employee Stock Option Plan (the "Plan") is
intended to provide incentives (a) to the employees of Teradyne, Inc. (the
"Company"), its parent (if any) and any present or future subsidiaries of the
Company (collectively, "Related Corporations") by providing them with
opportunities to purchase stock in the Company pursuant to options which
qualify as "incentive stock options" under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), granted hereunder ("ISO" or "ISOs"); and
(b) to directors, employees and consultants of the Company and Related
Corporations by providing them with opportunities to purchase stock in the
Company pursuant to non-statutory stock options granted hereunder ("NSO" or
"NSOs").  Both ISOs and NSOs are referred to hereafter individually as an
"Option" and collectively as "Options."  As used herein, the terms "parent" and
"subsidiary" mean "parent corporation" and "subsidiary corporation" as those
terms are defined in Section 425 of the Code.

     2.   Administration of the Plan.

          A.   Board or Committee Administration.  the Plan shall be
     administered by the Board of Directors of the Company (the
 "Board") or
     by a committee appointed by the Board (the "Committee"); provided, that to 
     the extent required by Rule 16b-3 of the Securities and Exchange 
     Commission ("Rule 16b-3") under the Securities and Exchange Act of 1934, 
     as amended (the "1934 Act"), with respect to specific grants of Options, 
     the Plan shall be administered by a disinterested administrator or 
     administrators within the meaning of Rule 16b-3.  Hereinafter all 
     references in this Plan to the "Committee" shall mean the Board if no 
     Committee has been appointed. Subject to ratification of the grant of each 
     Option by the Board (if so required by applicable state law), and subject 
     to the terms of the Plan, the Committee shall have the authority to (i) 
     determine the employees of the Company and Related Corporations (from 
     among the class of employees eligible under paragraph 3 to receive ISOs) 
     to whom ISOs may be granted, and to determine the inividuals and entities
     (from among the class of individuals and entities eligible under 
     paragraph 3 to receive NSOs) to whom NSOs may be granted; (ii) determine 
     the time or times at which Options may be granted; (iii) determine the 
     option price of shares subject to each Option; (iv) determine whether each
     Option granted shall be an ISO or a NSO; (v) determine (subject to 
     paragraph 7) the time or times when each Option shall become exercisable 
     and the duration of the exercise period;

<PAGE>   2
                                     - 2 -



     (vi) determine whether restrictions such as repurchase options are to
     be imposed on shares subject to Options, and the nature of such 
     restrictions if any, and (vii) interpret the Plan and prescribe and
     rescind rules and regulations relating to it.  The interpretation and
     construction by the Committee of any provisions of the Plan or of any 
     Option granted under it shall be final unless otherwise determined by the
     Board.  The Committee may from time to time adopt such rules and 
     regulations for carrying out the Plan as it may deem best.  No member of 
     the Board or the Committee shall be liable for any action or determination 
     made in good faith with respect to the Plan or any Option granted under it.

     3.   Eligible Employees and Others.  ISOs may be granted to any employee 
of the Company or any Related Corporation.  NSOs may be granted to any 
employee, consultant or director to the Company or any Related Corporation;
provided, that no Option may be granted hereunder to any non-employee director.
Granting of any Option to any individual or entity shall neither entitle that
individual or entity to, nor disqualify him from, participation in any other
grant of Options.

     4.   Stock.  The stock subject to Options shall be authorized but unissued
shares of Common Stock of the Company, par value $.125 per share (the "Common 
Stock"), or shares of Common Stock reacquired by the Company in any manner.  
The aggregate number of shares which may be issued pursuant to the Plan is 
6,000,000, subject to adjustment as provided in paragraph 13.  If any Option 
granted under the Plan shall expire or terminate for any reason without having 
been exercised in full or shall cease for any reason to be exercisable in whole 
or in part, the unpurchased shares subject thereto shall again be available for 
grants of Options under the plan.

     5.   Granting of Options.  Options may be granted under the Plan at any 
time after March 13, 1991 and prior to March 13, 2001.  The date of grant of an 
Option under the Plan will be the date specified by the Committee at the time 
it grants the Option, provided, however, that such date shall not be prior to 
the date on which the Committee acts to approve the grant.  The Committee shall 
have the right, with the consent of the optionee, to convert an ISO granted 
under the Plan to a NSO pursuant to paragraph 16.

     6.   Minimum Option Price; ISO Limitations.

          A.   Price for NSOs.  The price per share specified in the agreement 
     relating to each NSO granted under the Plan shall in no event be less than
     the minimum legal consideration therefor required under the laws of the 
     Commonwealth of Massachusetts.  No more than 200,000 NSOs may be granted 
     under the Plan for less than "fair market value" (as hereinafter defined).

                                     - 3 -


          B.   Price for ISOs.  The price per share specified in the agreement
     relating to each ISO granted under the Plan shall not be less than the
     fair market value per share of Common Stock on the date of such grant.  In
     the case of an ISO to be granted to an employee owning stock possessing
     more than ten percent of the total combined voting power of all classes of
     stock of the Company or any Related Corporation, the price per share
     specified in the agreement relating to such ISO shall not be less than 110
     percent of the fair market value of Common Stock on the date of grant.

          C.   $100,000 Annual Limitation on ISOs.  Each eligible employee may
     be granted ISOs only to the extent that, in the aggregate under this Plan
     and all incentive stock option plans of the Company and any Related
     Corporation, such ISOs do not become exercisable for the first time by
     such employee during any calendar year in a manner which would entitle the
     employee to purchase more than $100,000 in fair market value (determined
     at the time the ISOs were granted) of Common Stock in that year.  Any
     options granted to an employee in excess of such amount will be granted as
     Non-Qualified Options.

          D.   Determination of Fair Market Value.  If, at the time an Option
     is granted under the Plan, the Company's Common Stock is publicly traded,
     "fair market value" shall be determined as of the date such Option is
     granted and shall mean (i) the average (on that date) of the high, low and
     closing prices of the Common Stock on the principal national securities
     exchange on which the Common Stock is traded, if the Common Stock is then
     traded on a national securities exchange; or (ii) the last reported sale 
     price (on that date) of the Common Stock on the NASDAQ National Market 
     List, if the Common Stock is not then traded on a national securities 
     exchange; or (iii) the closing bid price (or average of bid prices) last 
     quoted (on that date) by an established quotation service or 
     over-the-counter securities, if the Common Stock is not reported on the 
     NASDAQ National Market List.  However, if the Common Stock is not publicly 
     traded at the time an Option is granted under the Plan, "fair market 
     value" shall be deemed to be the fair value of the Common Stock as 
     determined by the Committee after taking into consideration all factors 
     which it deems appropriate, including, without limitation, recent sale and 
     offer prices of the Common Stock in private transactions negotiated at 
     arm's length.

     7.   Option Duration.  subject to earlier termination as provided in
paragraphs 9 and 10, each Option shall expire on the date specified by the
Committee, but not more than (i) ten years and one day from the date of grant
in the case of NSOs, (ii) ten years from the date of grant in the case of ISOs
generally, and

<PAGE>   4
                                     - 4 -


(iii) five years form the date of grant in the case of ISOs granted to an
employee owning stock possessing more than ten percent of the total combined
voting power of all classes of stock of the Company or any Related Corporation.
Subject to earlier termination as provided in paragraphs 9 and 10, the term of
each ISO shall be the term set forth in the original instrument granting such
ISO, except with respect to any part of such ISO that is converted into a NSO
pursuant to paragraph 16.

     8.   Exercise of Option.  Subject to the provisions of paragraphs 9
through 12, each Option granted under the Plan shall be exercisable as follows:

          A.   Vesting.  The Option shall either be fully exercisable on the
     date of grant or shall become exercisable thereafter in such installments
     as the Committee may specify.

          B.   Full Vesting of Installments.  Once an installment becomes
     exercisable it shall remain exercisable until expiration or termination of
     the Option, unless otherwise specified by the Committee.

          C.   Partial Exercise.  Each Option or installment may be exercised
     at any time or from time to time, in whole or in part, for up to the total
     number of shares with respect to which it is then exercisable.

          D.   Acceleration of Vesting.  The Committee shall have the right to
     accelerate the date of exercise of any installment of any Option;
     provided, that the Committee shall not, without the consent of the
     optionee, accelerate the exercise date of any installment of any Option
     granted to any employee as an ISO (and not previously converted into a NSO
     pursuant to paragraph 16) if such acceleration would violate the annual
     vesting limitation contained in Section 422 of the Code, as described in
     paragraph 6(C).

     9.   Termination of Employment.  If an optionee ceases to be employed by
the Company and all Related Corporations other than by reason of death or
disability as defined in paragraph 10, no further installments of his Options
shall become exercisable, and his Options shall terminate after the passage of
90 days from the date of termination of his employment; provided, that the
Committee may specify that NSOs may remain exercisable for more than 90 days
from the date of termination of employment; provided, further, that in no event
shall any Option or part or installment thereof become or remain exercisable
after its specified expiration date.  Employment shall be considered as
continuing uninterrupted during any bona fide leave of absence (such as those
attributable to illness, military obligations or governmental service) provided
that the period of such leave does not exceed 90 days or, if longer, any period
during which such optionee's right to reemployment is guaranteed by statute.  A

<PAGE>   5
                                     - 5 -


bona fide leave of absence with the written approval of the Committee shall not
be considered an interruption of employment under the Plan, provided that such
written approval contractually obligates the Company or any Related Corporation
to continue the employment of the optionee after the approved period of
absence.  Options granted under the Plan shall not be affected by any change of
employment within or among the Company and Related Corporations, so long as the
optionee continues to be an employee of the Company or any Related Corporation.
Nothing in the Plan shall be deemed to give any grantee of any Option the right
to be retained in employment or other service by the Company or any Related
Corporation for any period of time.

     Notwithstanding anything to the contrary contained above, in the case of
normal retirement, NSOs granted to an optionee shall remain exercisable until
the date which is the earlier of (i) the NSOs' specified expiration date or
(ii) 90 days from the date upon which such optionee becomes employed by a
competitor of the Company, to the extent of the number of shares which have
vested prior to and during such period.  The Committee shall have the absolute
discretion to determine whether and as of what date any optionee is employed by
a competitor of the Company.

     10.  Death; Disability.

          A.   Death.  If an optionee ceases to be employed by the Company and
     all Related Corporations by reason of his death, any Option of his may be
     exercised, to the extent of the number of shares with respect to which he
     has theretofore been granted options (whether or not such options have
     vested in accordance with their terms) by his estate, personal
     representative or beneficiary who has acquired the Option by will or by
     the laws of descent and distribution, (i) in the case of ISOs, at any
     time prior to the earlier of the ISOs' specified expiration date or 180
     days from the date of the optionee's death or (ii) in the case of NSOs, at 
     any time prior to the earlier of the NSOs' specified expiration date or
     one year from the date of the optionee's death.

          B.   Disability.  If an optionee ceases to be employed by the Company
     and all Related Corporations by reason of his disability, any Option
     theretofore granted to such optionee shall remain exercisable until the
     date which is (i) in the case of ISOs, the earlier of the ISOs' specified
     expiration date or 180 days from the date of the termination of the
     optionee's employment or (ii) in the case of NSOs, the earlier of the
     NSOs' specified expiration date or 33 months from the date of the
     termination of the optionee's employment, to the extent of the number of
     shares (a) which, in the case of ISOs, have vested prior to and during the
     period specified in clause (i) and (b) which, in the case of NSOs, have
     vested prior to and during the period which is 30 months from the date the
     optionee ceases to be employed by

<PAGE>   6
                                     - 6 -


     the Company.  for the purposes of this Plan, the term "disability" shall
     mean "permanent and total disability" as defined in Section 22(e)(3) of
     the Code or any successor statue.

     11.  Assignability.  No Option shall be assignable or transferable by the
optionee except by will or by the laws of descent and distribution, and during
the lifetime of the optionee each Option shall be exercisable only by him.

     12.  Terms and Conditions of Options.  Options shall be evidenced by
instruments (which need not be identical) in such forms as the Committee may
from time to time approve.  Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which ate not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options.  The Committee may from time to time confer
authority and responsibility on one or more of its own members and/or one or
more officers of the Company to execute and deliver such instruments.  The
proper officers of the Company are authorized and directed to take any and all
action necessary or advisable form time to time to carry out the terms of such
instruments.

     13.  Adjustments.  Upon the occurrence of any of the following events, an
optionee's rights with respect to Options granted to him hereunder shall be
adjusted as hereinafter provided, unless otherwise specifically provided in the
written agreement between the optionee and the Company relating to such
Option:

          A.   Stock Dividends and Stock Splits.  If the shares of Common Stock
     shall be subdivided or combined into a greater or smaller number of shares
     or if the Company shall issue any Common Stock, the number of shares of
     Common Stock deliverable upon the exercise of Options shall be
     appropriately increased or decreased proportionately, and appropriate
     adjustments shall be made in the purchase price per share to reflect such
     subdivision, combination or stock dividend.

          B.   Consolidations or Mergers.  If the Company is to be consolidated
     with or acquired by another entity in a merger, sale of all or
     substantially all of the Company's assets or otherwise (an "Acquisition"),
     the Committee or the board of directors of any entity assuming the
     obligations of the Company hereunder (the "Successor Board"), shall, as to
     outstanding Options, either (i) make appropriate provision for the
     continuation of such Options by substituting on an equitable basis for the
     shares then subject to such Options the consideration payable with respect
     to the outstanding

<PAGE>   7
                                      -7-

shares of Common Stock in connection with the Acquisition; or (ii) upon written
notice to the Optionees, provide that all Options must be exercised, to the
extent then exercisable, within a specified number of days of the date of such
notice, at the end of which period the Options shall terminate; or (iii)
terminate all optionees in exchange for a cash payment equal to the excess of 
the fair market value of the shares subject to such Options (to the extent then
exercisable) over the exercise price thereof.

       C.     Recapitalization or Reorganization.  In the event of a
recapitalization or reorganization of the Company (other than a transaction
described in subparagraph B above) pursuant to which securities of the Company
or of another corporation are issued with respect to the outstanding shares of
Common Stock, an optionee upon exercising an Option shall be entitled to
receive for the purchase price paid upon such exercise the securities he would
have received if he had exercised his Option prior to such recapitalization or
reorganization.

       D.     Modification of ISOs.  Notwithstanding the foregoing, any
adjustments made pursuant to subparagraphs A, B or C with respect to ISOs shall
be made only after the Committee, after consulting with counsel for the
Company, determines whether such adjustments would constitute a "modification"
of such ISOs (as that term is defined in Section 425 of the Code) or would
cause any adverse tax consequences for the holders of such ISOs.  If the
Committee determines that such adjustments made with respect to ISOs would
constitute a modification of such ISOs, it may refrain from making such
adjustments.

       E.     Dissolution of Liquidation.  In the event of the proposed or
liquidation of the Company, each Option will terminate immediately prior to the
consummation of such proposed action or at such other time and subject to such
other conditions as shall be determined by the Committee.

       F.     Issuances of Securities.  Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
subject to Options.  No adjustments shall be made for dividends paid in cash or
in property other than securities of the Company.

       G.     Fractional Shares.  No fractional shares shall be issued under
the Plan and the optionee shall receive from the Company cash in lieu of such
fractional shares.

<PAGE>   8
                                      -8-

              H.    Adjustments.  Upon the happening of any of the events
       described in subparagraphs A, B or C above, the class and aggregate      
       number of shares set forth in paragraph 4 hereof that are subject to
       options which previously have been or subsequently may be granted under
       the Plan shall also be appropriately adjusted to reflect the events
       described in such subparagraphs.  The Committee or the Successor Board
       this paragraph 13 and, subject to paragraph 2, its determination shall
       be conclusive.

       If any person or entity owning restricted Common Stock obtained by
exercise of an Option receives shares or securities or cash in connection with
a corporate transaction described in subparagraphs A, B or C above as a result
of owning such restricted Common Stock, such shares or securities or cash shall
be subject to all of the conditions and restrictions applicable to the
restricted Common Stock with respect to which such shares or securities or cash
were issued, unless otherwise determined by the Committee or the Successor
Board.

       14.    Means of Exercising Options.  An Option (or any part or
installment thereof) shall be exercised by giving written notice to the Company
at its principal office address.  Such notice shall identify the Option being
exercised and specify the number of shares as to which such Option is being
exercised, accompanied by full payment of the purchase price therefor either
(a) in United States dollars in cash or by check, or (b) at the discretion of
the Committee, through delivery of shares of Common Stock having fair market
value equal as of the date of the exercise Lo the cash exercise price of the
Option, or (c) at the discretion of the Committee in exceptional cases, by
delivery of the optionee's personnel recourse note bearing interest payable not
less than annually at no less than 100% of the lowest applicable Federal rate,
as defined in Section 1274(d) of the Code, or (d) at the discretion of the
Committee, by any combination of (a), (b) and (c) above.  If the Committee
exercises its discretion to permit payment of the exercise price of an ISO by
means of the methods set forth in clauses (b) or (c) of the preceding sentence,
such discretion shall be exercised in writing at the time of the grant of the
ISO in question.  Alternatively, payment may be made in whole or in part in
shares of the Common Stock of the Company already owned by the person or
persons exercising the option or shares subject to the option being exercised
(subject to such restrictions and guidelines as the Board may adopt from time
to time), or consistent with applicable law, through the delivery of an
assignment to the Company of a sufficient amount of the proceeds from the sale
of the Common Stock acquired upon exercise of the option and an authorization
to the broker or selling agent to pay that amount to the Company, which sale
shall be at the participant's direction at the time of exercise.  The holder of
an Option shall not have the rights of a shareholder with respect to the shares

<PAGE>   9
                                      -9-

covered by his Option until the date of issuance of a stock certificate to him
for such shares.  Except as expressly provided above in paragraph 13 with
respect to changes in capitalization and stock dividends, no adjustment shall
be made for dividends or similar rights for which the record date is before the
date such stock certificate is issued.

       15.    Term and Amendment of Plan.  This Plan was adopted by the Board
on March 13, 1991, and shall expire on the end of the day on March 13, 2001
(except as to Options outstanding on that date).  The Board may at any time
terminate the Plan or make such modification or amendment thereof as it deems
advisable, provided, however, that the Board may not, without approval by the
affirmative vote of the holders of a majority of the securities of the Company
present, or represented, and entitled to vote at a meeting duly held in
accordance with the applicable laws of the state in which the Company is
incorporated, (i) materially increase the benefits accruing to participants
under the Plan; (ii) increase the number of shares for which options may be
granted under the Plan; or (iii) materially modify the requirements as to
eligibility for participation in the Plan.  Termination or any modification or
amendment of the Plan shall not, without consent of a participant, affect his
rights under an option previously granted to him.

       16.    Conversion of ISOs into NSOs; Termination of ISOs.  The
Committee, with the written approval of any optionee, may in its discretion
take such actions as may be necessary to convert such optionee's ISOs (or any
installments of portions of installments thereof) that have not been exercised
on the date of conversion into NSOs at any time prior to the expiration of such
ISOs regardless of whether the optionee is an employee of the Company or a
Related Corporation at the time of such conversion.  Such actions may include,
but not be limited to, extending the exercise period or reducing the exercise
price of the appropriate installments of such Options.  At the time of such
conversion, the Committee (with the consent of the optionee) may impose such
conditions on the exercise of the resulting NSOs as the Committee in its
discretion may determine, provided that such conditions shall not be
inconsistent with the Plan.  Nothing in the Plan shall be deemed to give any
optionee the right to have such optionee's ISOs converted into NSOs, and no
such conversion shall occur until and unless the Committee takes appropriate
action.  The Committee, with the consent of the optionee, may also terminate
any portion of any ISO that has not been exercised at the time of such
termination.

       17.    Application of Funds.  The proceeds received by the Company from
the sale of shares pursuant to Options granted under the Plan shall be used for
general corporate purposes.

<PAGE>   10
                                      -10-

       18.    Governmental Regulation.  The Company's obligation to sell and
deliver shares of Common Stock under this Plan is subject to the approval of
any governmental authority required in connection with the authorization,
issuance or sale of such shares.

       19.    Withholding of Additional Income Taxes.  Upon the exercise of a
NSO, the making of a Disqualifying Disposition (as defined in paragraph 20) or
the vesting of restricted Common Stock acquired on the exercise of an Option,
the Company, in accordance with Section 3402(a) of the Code, may require the
optionee to pay additional withholding in respect of the amount that is
considered compensation includible in such person's gross income.  The
Committee in its discretion may condition (i) the exercise of an Option or (ii)
the vesting of restricted Common Stock acquired by exercising an Option, on the
optionee's payment of such additional withholding taxes.

       20.    Notice to Company of Disqualifying Disposition.  Each employee
who receives ISOs shall agree to notify the Company in writing immediately
after the employee makes a disqualifying disposition of any Common Stock
received pursuant to the exercise of an ISO (a "Disqualifying Disposition").
Disqualifying Disposition means any disposition (including any sale) of such
stock before the later of (a) two years after the employee was granted the ISO
under which he acquired such stock, or (b) one year after the employee acquired
such stock by exercising such ISO.  If the employee has died before such stock
is sold, these holding period requirements do not apply and no Disqualifying
Disposition will thereafter occur.

       21.    Governing Laws; Construction.  The validity and construction of
the Plan and the instruments evidencing Options shall be governed by the laws
of the Commonwealth of Massachusetts.  In construing this Plan, the singular
shall include the plural and the masculine gender shall include the feminine
and neuter, unless the context otherwise requires.
