                                PROXY STATEMENT
                                 APRIL 20, 1998
 
     Proxies in the form enclosed with this proxy statement ARE SOLICITED BY THE
BOARD OF DIRECTORS OF TERADYNE, INC. (the "Corporation") for use at the Annual
Meeting of Shareholders (the "Annual Meeting") to be held on May 21, 1998, at
10:00 A.M., at BankBoston, 100 Federal Street (Second Floor), Boston,
Massachusetts.
 
     Only shareholders of record as of the close of business on April 6, 1998
(the "Record Date"), will be entitled to vote at the Annual Meeting and any
adjournments thereof. As of the Record Date, 83,475,046 shares (excluding
treasury shares) of Common Stock of the Corporation were issued and outstanding.
Each share outstanding as of the Record Date will be entitled to one vote, and
shareholders may vote in person or by proxy. Execution of a proxy will not in
any way affect a shareholder's right to attend the Annual Meeting and vote in
person. Any shareholder delivering a proxy has the right to revoke it only by
written notice to the Clerk delivered at any time before it is exercised,
including at the Annual Meeting.
 
     The persons named as attorneys in the proxies are officers and directors of
the Corporation. All properly executed proxies returned in time to be cast at
the Annual Meeting will be voted. With respect to the election of Directors, any
shareholder submitting a proxy has a right to withhold authority to vote for any
individual nominee by writing that nominee's name in the space provided on the
proxy. The proxies will be voted as stated below under "Election of Directors."
In addition to the election of Directors, the shareholders will consider and
vote upon proposals (i) to approve an amendment to the 1996 Employee Stock
Purchase Plan and (ii) to ratify the selection of auditors. Where a choice has
been specified on the proxy with respect to the foregoing matters, the shares
represented by the proxy will be voted in accordance with the specification and
will be voted FOR if no specification is indicated.
 
     A majority in interest of the outstanding shares represented at the meeting
in person or by proxy shall constitute a quorum for the transaction of business.
Votes withheld from any nominee, abstentions and broker "non-votes" are counted
as present or represented for purposes of determining the presence or absence of
a quorum for the meeting. A "non-vote" occurs when a nominee holding shares for
a beneficial owner votes on one proposal, but does not vote on another proposal
because the nominee does not have discretionary voting power and has not
received instructions from the beneficial owner. Directors are elected by a
plurality of the votes cast by shareholders entitled to vote at the meeting. On
all other matters being submitted to shareholders, an affirmative vote of at
least a majority of the shares present, or represented, and voting at the
meeting is required for approval. An automated system administered by the
Corporation's transfer agent tabulates the votes. The vote on each matter
submitted to shareholders is tabulated separately. Abstentions are included in
the number of shares present or represented and voting on each separate matter.
Broker "non-votes" are not so included.
 
     The Board of Directors knows of no other matter to be presented at the
Annual Meeting. If any other matter should be presented at the Annual Meeting
upon which a vote properly may be taken, shares represented by all proxies
received by the Board of Directors will be voted with respect thereto in
accordance with the judgment of the persons named as attorneys in the proxies.
 
     An Annual Report to Shareholders, containing financial statements for the
fiscal year ended December 31, 1997, has been mailed to all shareholders
entitled to vote at the Annual Meeting. This proxy statement and the
accompanying proxy were first mailed to shareholders on or about April 20, 1998.
<PAGE>   4
 
                             ELECTION OF DIRECTORS
 
     The Corporation's Board of Directors is divided into three classes. Each
class serves three years, with the terms of office of the respective classes
expiring in successive years. The present term of office for the directors in
Class III expires at the Annual Meeting. The nominees for election as Class III
directors are Messrs. Mulroney, Robbins and Testa and Ms. Wolpert, each of whom,
except for Ms. Wolpert, was elected at the Annual Meeting of Shareholders held
May 24, 1995. Ms. Wolpert was appointed to the Board of Directors in September
1996. If re-elected, the Class III nominees will hold office until the Annual
Meeting of Shareholders to be held in 2001, and until their successors shall
have been elected and shall have been qualified. Shares represented by all
proxies received by the Board of Directors and not so marked as to withhold
authority to vote for any individual nominee will be voted (unless one or more
nominees are unable or unwilling to serve) for the election of the Class III
nominees. The Board of Directors knows of no reason why any such nominee should
be unable or unwilling to serve, but if such should be the case, proxies will be
voted for the election of some other person or the Board of Directors will fix
the number of directors at a lesser number.
 
     The following table sets forth the nominees to be elected at the Annual
Meeting and the other current directors, the year each nominee or director was
first appointed or elected a director, the principal occupation of each of the
nominees and directors during the past five years, and the ages of each of the
nominees and directors.

DIRECTOR COMPENSATION
 
     All non-employee directors are compensated at the rate of $20,000 per year
and $1,500 per meeting attended, plus reimbursement of reasonable expenses.
Directors who are employees of the Corporation receive no compensation in their
capacity as a director.
 
     Each director who is not an employee or officer of the Corporation (a
"Non-Employee Director") is entitled to participate in the Corporation's 1996
Non-Employee Director Stock Option Plan (the "Director Plan"). The Director Plan
authorizes the automatic grant of (i) an option to purchase 15,000 shares of the
Corporation's Common Stock to each Non-Employee Director who becomes a member of
the Corporation's Board of Directors on or after January 1, 1997 and (ii) an
option to purchase 7,500 shares of the Corporation's Common Stock to each person
who is a Non-Employee Director on the first Monday of February in each year
beginning on February 3, 1997. The Director Plan is administered by the Stock
Option Committee of the Board of Directors of the Corporation. Options granted
under the Director Plan vest at the rate of 25% per year. The exercise price per
share for all options granted under the Director Plan is equal to the fair
market value per share of the Corporation's Common Stock on the date of grant,
and the term of each option is for a period of five years from the date of
grant.
 
     As of December 31, 1997, options to purchase 52,500 shares of the
Corporation's Common Stock under the Director Plan were outstanding at a
weighted average exercise price of $30.88.

(1) Stock options were granted under the Corporation's 1991 Employee Stock
    Option Plan at an exercise price equal to the fair market value of the
    Corporation's Common Stock on the date of grant. The options have a term of
    five years from the date of grant. The options become exercisable as
    follows: 20% on the date of grant and, following the first year of grant,
    20% on an annual basis.
 
(2) Amounts reported in these columns represent amounts that may be realized
    upon exercise of the options immediately prior to the expiration of their
    term assuming the specified compounded rates of appreciation (5% and 10%) of
    the Corporation's Common Stock over the term of the options. These numbers
    are calculated based on rules promulgated by the Securities and Exchange
    Commission and do not reflect the Corporation's estimate of future stock
    price increases. Actual gains, if any, on stock option exercises and Common
    Stock holdings are dependent on the timing of such exercise and the future
    performance of the Corporation's Common Stock. There can be no assurance
    that the rates of appreciation assumed in this table can be achieved or that
    the amounts reflected will be received by the individuals.

RETIREMENT BENEFITS
 
     The Corporation has established a Retirement Plan for the purpose of
providing a lifetime annual income upon retirement to substantially all
employees, including officers, of the Corporation and its United States
subsidiaries. Membership in the Retirement Plan begins after one year of
employment with the Corporation. The Retirement Plan provides for credit toward
retirement income for years of employment with the Corporation prior to January
1, 1994 based upon a formula tied to average compensation from 1989 to 1993. For
years of service after December 31, 1993, credit towards retirement income is
determined on a yearly basis and is equal to the sum for each year of credited
service under the Retirement Plan of (1) .75% of the employee's compensation for
the year which is under the defined covered compensation for the year and (2)
1.5% of the amount of the employee's compensation for the year that exceeds the
covered compensation for the year. The covered compensation under the Retirement
Plan is based on the average of the social security wage basis in effect during
the thirty-five years up to and including normal retirement age. However,
federal tax law limitations on the total amount of benefits which a participant
may receive under qualified retirement plans may limit some participants'
benefits under the Retirement Plan.
 
     Under the Retirement Plan, for participants employed by the Corporation on
or after January 1, 1989, accumulated annual retirement income vests partially
after three years of service with the Corporation and becomes fully vested after
seven years of service or upon normal, early or disability retirement. Benefits
are payable in the form of an annuity either at normal retirement age, upon
early retirement or upon disability. The Retirement Plan also provides for
certain benefits to a surviving spouse.
 
     The Corporation also maintains the Teradyne, Inc. Supplemental Executive
Retirement Plan (the "SERP"). Under the SERP, annual pensions for Messrs.
d'Arbeloff, Chamillard, Rogas, Casey, Bradley and Hotchkiss and other senior
managers are computed based on model compensation. See discussion of model
compensation under Management and Compensation Development Committee Report. The
pension formula is identical to that of the qualified plan, except an employee's
annual pension is based on the average of the employee's last five years of
model compensation. The resulting benefit is reduced by the benefit received
from the qualified Retirement Plan.

     The following table shows the estimated annual benefits payable to covered
participants in the United States upon retirement at age 65 under both the
Retirement Plan and the SERP. The amounts shown are computed on a single life
annuity basis and are not subject to deductions for Social Security benefits or
other amounts. Remuneration for purposes of the table is based upon an
employee's average model compensation for the five year period preceding
retirement.

                          MANAGEMENT COMPENSATION AND
                        DEVELOPMENT COMMITTEE REPORT AND
                         STOCK OPTION COMMITTEE REPORT
 
OVERVIEW AND PHILOSOPHY
 
     The Corporation's executive compensation program is administered by the
Management Compensation and Development Committee of the Board of Directors (the
"Compensation Committee"), which is comprised entirely of outside directors. The
Compensation Committee is responsible for developing and making recommendations
to the Board of Directors with respect to the Corporation's compensation
policies other than with respect to stock option awards. In addition, the
Compensation Committee, pursuant to authority delegated by the Board of
Directors, determines on an annual basis the cash compensation to be paid to
each of the executive officers. The Stock Option Committee is comprised entirely
of non-employee directors. The Stock Option Committee is responsible for
developing and making recommendations to the Board of Directors with respect to
the Corporation's compensation policies in connection with the awarding of stock
options. In addition, the Stock Option Committee, pursuant to authority
delegated by the Board of Directors, determines on an annual basis the stock
option awards to be granted to each of the executive officers.
 
     The executive compensation policies are designed to provide competitive
levels of compensation that assist the Corporation in attracting and retaining
qualified executives. In setting cash compensation levels for executive
officers, the Compensation Committee takes into account such factors as: the
Corporation's past history and future expectations; the general and
industry-specific business environment; annual and long-term performance goals;
and corporate and group performance.
 
EXECUTIVE OFFICER COMPENSATION PROGRAM
 
     The Corporation's executive officer compensation program consists of
compensation received pursuant to the Corporation's Cash Compensation Plan, Cash
Profit Sharing Plan, long-term compensation in the form of stock option, savings
and retirement plans and various other benefits generally available to employees
of the Corporation.
 
     Under the Corporation's Cash Compensation Plan, the Compensation Committee
assigns to each senior employee of the Corporation, including all executives
officers, at the beginning of each year, a "model compensation" amount. The
model compensation amount is based on salary surveys of similarly sized
electronics companies, and on an as adjusted basis, larger sized companies, some
of which are represented in the S&P High Technology Composite Index appearing in
the Performance Graph on page 15 herein.
 
     Once model compensation for each participant has been determined, the
actual cash compensation paid to each employee under the Cash Compensation Plan
is comprised of two components: (1) a fixed monthly salary and (2) an annual
variable amount based upon overall corporate and group performance (referred to
herein as "Variable Compensation"). The fixed salary amount is set at a level
which is below the model compensation, and the variable portion is based upon
factors which, if achieved, would entitle the employee to reach or exceed model
compensation.
 
     The amount of Variable Compensation each participant receives is a function
of four factors:
 
          (A) The employee's base annual salary as of the end of the year;
 
          (B) Overall corporate performance versus goal;
 
          (C) Performance of the individual business group versus goal; and
 
                                       11
<PAGE>   14
 
          (D) The employee's "variable compensation factor," which is determined
     by the Compensation Committee on the basis of responsibility and experience
     level.
 
     An employee's "variable compensation factor" is a percentage of his or her
base annual salary starting at 10% for new participants. At greater levels of
responsibility and experience, the variable compensation factor may increase to
more than 150% of base annual salary. An employee's model compensation is set
assuming a 50% payout of the variable compensation factor. Accordingly, in a
given year an employee may achieve more or less than his or her model
compensation depending on corporate and business group performance.
 
     At year end, the Compensation Committee evaluates the Corporation's overall
performance versus goal and each individual group's performance versus goal.
Given the dynamics of the business, the Corporation's Cash Compensation Plan
relies heavily on the Compensation Committee's subjective judgment of
performance.
 
     Specifically for 1997, in determining Variable Compensation payouts, the
Compensation Committee took the following factors into consideration in
evaluating both overall corporate performance and the performance of the
Corporation's individual business groups: (1) the extent to which quantitative
and qualitative plans were met for the year, with an emphasis on profitability,
growth of sales, growth of bookings, and increase in market share; (2) the
extent to which each business group became a role model in the implementation of
"Total Quality Management"; (3) the extent to which the results for the year
verified each group's strategy and improved its strategic position; and (4) the
extent to which each group has a strategy and an aggressive and credible 1998
mid-term plan that supports the Corporation's growth, profit and market share
objectives. The Compensation Committee weighed each of the four factors
approximately equally in setting Variable Compensation amounts. The factors are
reviewed by the Compensation Committee based upon the performance of the
business group in which each executive officer serves rather than upon the
individual performance of the executive officer. In 1997, total cash
compensation for all executive officers from the Corporation's Cash Compensation
Plan ranged from approximately 10% to 25% above model compensation.
 
     The Corporation's stock option program is the Corporation's long-term
incentive plan for employees, including executive officers. The objectives of
the program are to align executive return with shareholder return and to create
and implement a program which will attract and retain talented employees and
executives. Stock options are awarded annually to employees, including the Chief
Executive Officer, based upon an employee's relative contribution and
responsibility within the Corporation. The factors taken into account by the
Stock Option Committee in determining each executive officer's relative
contribution and responsibility within the Corporation include: the executive
officer's level of model compensation, the executive officer's position, the
responsibilities currently being performed by the executive officer, and the
responsibilities expected to be performed by the executive officer. The
individual factors are reviewed subjectively by the Stock Option Committee when
determining stock option awards for each executive officer. The Corporation
conducts surveys of various companies, some of which appear in the Performance
Graph's S&P High Technology Composite Index, to verify that the relative
percentages of stock options granted to its employees, its Chief Executive
Officer and its other executive officers, are consistent with high technology
industry practice, are within the range of stock options granted by the surveyed
companies, and are competitive with the relative percentages of stock options
granted by the surveyed companies.
 
CHIEF EXECUTIVE OFFICER COMPENSATION
 
     Mr. Chamillard's cash compensation for 1997 awarded under the Corporation's
Cash Compensation Plan was $827,863, which is approximately 25.5% more than Mr.
Chamillard's 1997 model compensation of $659,625. Mr. Chamillard's 1997 cash
compensation awarded pursuant to the Corporation's Cash Compensation Plan is a
78.6% increase over his 1996 cash compensation. Mr. Chamillard was appointed as
Chief
 
                                       12
<PAGE>   15
 
Executive Officer in May 1997 and his model compensation was adjusted at this
time by the Compensation Committee to reflect his new position. Mr. Chamillard's
fixed salary amount was $353,742 for 1997 and was set by the Compensation
Committee, in conjunction with his model compensation amount, based upon salary
surveys of chief executive officers for similarly sized electronics companies.
Mr. Chamillard's Variable Compensation payout was $474,121 for 1997. Mr.
Chamillard's Variable Compensation payouts are determined based upon the same
factors as the Corporation's other executive officers who have general
responsibilities within the Corporation rather than responsibilities for one
specific business group within the Corporation. Each of such executive officer's
Variable Compensation payout is based 50% upon the performance of the
Corporation as a whole and 50% upon the average of the performances of each of
the individual business groups within the Corporation. Mr. Chamillard also
received cash compensation in the amount of $57,328 in 1997 pursuant to the
Corporation's Cash Profit Sharing Plan. Cash compensation awards under such
plan, which are calculated on a uniform basis as a percentage of the recipient's
salary, are made to the employees of the Corporation on an equal basis.
 
     The stock options granted to Mr. Chamillard during fiscal year 1997 are
consistent with the design of the overall program and are shown in the Summary
Compensation Table above. Mr. Chamillard's 80,000 shares, which represented
2.52% of the total option shares awarded to all employees during fiscal year
1997, placed him at the median of the external surveys. In assessing Mr.
Chamillard's individual performance for the year for purposes of his stock
option awards, the Stock Option Committee concluded that, on balance, Mr.
Chamillard had achieved overall positive results for the individual factors for
which he was evaluated. A general description of these factors is detailed above
under the description of the Corporation's stock option program.

COMPENSATION COMMITTEE INTERLOCK AND INSIDER PARTICIPATION
 
     Messrs. Bagley, Hibbard and Testa and Ms. Wolpert comprised the
Compensation Committee for fiscal year 1997. Richard J. Testa is a member of the
law firm Testa, Hurwitz & Thibeault, LLP in Boston, Massachusetts. Such law firm
served as general counsel for the Corporation during the fiscal year 1997 and
the Corporation expects to retain the services of such firm for the fiscal year
1998.
 
DEDUCTIBILITY OF EXECUTIVE COMPENSATION
 
     In general, under Section 162(m) of the Internal Revenue Code of 1986, as
amended (the "Code"), the Corporation cannot deduct, for federal income tax
purposes, compensation in excess of $1,000,000 paid to certain executive
officers. This deduction limitation does not apply, however, to compensation
that constitutes "qualified performance-based compensation" within the meaning
of Section 162(m) of the Code and the regulations promulgated thereunder. The
Corporation has considered the limitations on deductions imposed by Section
162(m) of the Code, and it is the Corporation's present intention that, for so
long as it is consistent
 
                                       13
<PAGE>   16
 
with its overall compensation objectives, substantially all tax deductions
attributable to executive compensation will not be subject to the deduction
limitations of Section 162(m) of the Code.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     In May 1997, James A. Prestridge and Owen W. Robbins retired as Executive
Vice Presidents of the Corporation. On June 1, 1997, the Corporation entered
into consulting agreements with each of Messrs. Prestridge and Robbins, pursuant
to which Messrs. Prestridge and Robbins agreed to provide advice and consulting
services to the Corporation. In consideration for their services, the
Corporation granted each of Messrs. Prestridge and Robbins options to purchase
up to 90,000 shares of the Corporation's Common Stock pursuant to the
Corporation's 1991 Employee Stock Option Plan, which options shall vest
throughout the term of the applicable agreement. In addition, pursuant to such
consulting agreements, the Corporation agreed to pay each of Messrs. Prestridge
and Robbins $22,353.00 per month throughout the term of his respective
agreement. Each agreement is for a period of three years and is terminable by
either party upon sixty (60) days' prior written notice.

                      PROPOSAL TO APPROVE AN AMENDMENT TO
                       1996 EMPLOYEE STOCK PURCHASE PLAN
 
PROPOSED AMENDMENT
 
     In March 1998, the Board of Directors adopted an amendment to the 1996
Employee Stock Purchase Plan (the "1996 Purchase Plan") which is the subject of
this proposal. The Board of Directors has approved and recommends to the
shareholders that they approve an amendment to the 1996 Purchase Plan that will
increase the aggregate number of shares authorized for issuance under the 1996
Purchase Plan by 2,000,000 shares.
 
     The Corporation's management relies on stock purchases as an essential part
of the compensation packages necessary for the Corporation to attract and retain
experienced officers and employees. The Board of Directors of the Corporation
believes that the proposed amendment is essential to permit the Corporation's
management to continue to provide long-term, equity-based incentives to present
and future key employees.
 
     The 1996 Purchase Plan was adopted by the Board of Directors on March 19,
1996, and approved by the Company's shareholders on April 18, 1996. In March
1998, the Board of Directors adopted the amendment to the 1996 Purchase Plan
which is the subject of this proposal.
 
     As of December 31, 1997, only 122,828 shares remained authorized for
issuance under the 1996 Purchase Plan. If the increase in the number of shares
authorized for issuance under the 1996 Purchase Plan is not approved, the
Corporation may become unable to provide suitable long-term equity-based
incentives to present and future employees.
 
DESCRIPTION OF THE 1996 PURCHASE PLAN
 
     The 1996 Purchase Plan is intended to provide an incentive to, and to
encourage stock ownership by, all eligible employees of the Corporation and its
participating subsidiaries so that they may share in the growth of the
Corporation by acquiring or increasing their proprietary interest in the
Corporation. The 1996 Purchase Plan is designed to encourage eligible employees
to remain in the employ of the Corporation and its participating subsidiaries.
Under the 1996 Purchase Plan, payroll deductions are used to purchase the
Corporation's Common Stock for eligible, participating employees through the
exercise of stock options.
 
     The 1996 Purchase Plan constitutes an "employee stock purchase plan" within
the meaning of Section 423(b) of the Internal Revenue Code of 1986, as amended
(the "Code").
 
     The 1996 Purchase Plan is administered by the Stock Option Committee of the
Board of Directors of the Corporation. The Stock Option Committee, subject to
the provisions of the 1996 Purchase Plan, has the power to construe the 1996
Purchase Plan, to determine all questions thereunder, and to adopt and amend
such rules and regulations for administration of the 1996 Purchase Plan as it
may deem appropriate. The Stock Option Committee or the Board of Directors may
from time to time adopt amendments to the 1996 Purchase Plan provided that,
without the approval of the Corporation's shareholders, no amendment may
increase the number of shares that may be issued under the 1996 Purchase Plan or
change the class of the employees eligible to receive options under the 1996
Purchase Plan, or cause Rule 16b-3 under the Securities Exchange Act of 1934 to
be inapplicable to the 1996 Purchase Plan.
 
     The 1996 Purchase Plan may be terminated at any time by the Corporation's
Board of Directors; however such termination will not affect options then
outstanding under the 1996 Purchase Plan. If at any time shares of Common Stock
reserved for the purpose of the 1996 Purchase Plan remain available for
purchase, but not in sufficient number to satisfy all then unfilled purchase
requirements, the available shares will be apportioned among participants in
proportion to the amount of payroll deductions accumulated on behalf of each
 
                                       16
<PAGE>   19
 
participant that would otherwise be used to purchase stock, and the 1996
Purchase Plan will terminate. Upon termination of the 1996 Purchase Plan, all
payroll deductions not used to purchase Common Stock will be refunded to 1996
Purchase Plan participants without interest.
 
     As amended, the 1996 Purchase Plan would authorize the issuance of up to
2,700,000 shares of Common Stock (subject to adjustment for capital changes)
pursuant to the exercise of non-transferable options granted to participating
employees. The Common Stock subject to the options under the 1996 Purchase Plan
includes shares of the Corporation's authorized but unissued Common Stock and
shares of Common Stock reacquired by the Corporation, including shares purchased
in the open market. Option holders are generally protected against dilution in
the event of certain capital changes such as a recapitalization, stock split,
merger, consolidation, reorganization, combination, liquidation, stock dividend
or similar transaction.
 
     An employee electing to participate in the 1996 Purchase Plan must
authorize an amount (a whole percentage not less than 2% nor more than 10% of
the employee's cash compensation) to be deducted by the Corporation from the
employee's pay and applied toward the purchase of Common Stock under the 1996
Purchase Plan. For the duration of the 1996 Purchase Plan, the Payment Period is
defined as the twelve-month period commencing on the first day of January and
ending annually on the last day of December of each calendar year. However, the
first Payment Period for the 1996 Purchase Plan commenced on July 1, 1996 and
ended on December 31, 1996.
 
     Employees of the Corporation (and participating subsidiaries) who have
completed more than 90 days of employment with the Corporation or any of its
subsidiaries (i) on or before the first day of any Payment Period or (ii) for
employees first employed after the ninetieth day prior to the first day of a
particular Payment Period, on or before the first day of the next succeeding
July in any such Payment Period, and whose customary employment is not less than
20 hours per week and more than 5 months per calendar year are eligible to
participate in the 1996 Purchase Plan. An employee may not be granted an option
under the 1996 Purchase Plan if, after the granting of the option, such employee
would be treated as owning 5% or more of the total combined voting power or
value of all classes of stock of the Corporation or its subsidiaries. Directors
who are not employees of the Corporation may not participate in the 1996
Purchase Plan.
 
     On the first business day of each Payment Period (or the first business day
of the portion of a Payment Period beginning July 1, in the case of employees
who participate in the 1996 Purchase Plan effective July 1 of that Payment
Period), the Corporation will grant to each 1996 Purchase Plan participant an
option to purchase shares of Common Stock of the Corporation. On the last day of
the Payment Period, the employee will be deemed to have exercised this option,
at the option price, to the extent of such employee's accumulated payroll
deductions, on the condition that the employee remains eligible to participate
in the 1996 Purchase Plan throughout the Payment Period. In no event, however,
may the employee exercise an option granted under the 1996 Purchase Plan for
more than 3,000 shares during a Payment Period. If the amount of the accumulated
payroll deductions exceeds the aggregate purchase price of 3,000 shares, the
excess deductions will be promptly refunded to the employee without interest.
Furthermore, no employee may be granted an option which permits the employee's
right to purchase shares of Common Stock under the 1996 Purchase Plan and all
other Section 423 plans of the Corporation and any subsidiary corporations, to
accrue at a rate which exceeds $25,000 of fair market value of such stock
(determined on the respective date(s) of grant) for each calendar year in which
the option is outstanding. Any excess accumulation of payroll deductions will be
promptly refunded to the employee without interest. Under the terms of the 1996
Purchase Plan, the option price is an amount equal to the lesser of (i) 85% of
the fair market value of the Common Stock on the first business day of the
Payment Period (or the first business day of the portion of a Payment Period
beginning July 1, in the case of employees who participate in the 1996 Purchase
Plan effective July 1 of that Payment Period), and (ii) 85% of the fair market
value of the Common Stock on the last business day of the Payment
 
                                       17
<PAGE>   20
 
Period. The Corporation will accumulate and hold for the employee's account the
amounts deducted from his pay. No interest will be paid on these amounts.
 
     For purposes of the 1996 Purchase Plan, the term "fair market value" on any
date means (i) the average (on that date) of the high and low 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 Stock Market, if the Common Stock is not then traded on a
national securities exchange; or (iii) the average of the closing bid and asked
prices last quoted (on that date) by an established quotation service for
over-the-counter securities, if the Common Stock is not reported on The Nasdaq
Stock Market; or (iv) if the Common Stock is not publicly traded, the fair
market 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. An employee may enter the 1996 Purchase
Plan by delivering to the Corporation, at least 30 days before the beginning
date of the next succeeding Payment Period (or at least 15 days prior to July 1
of such Payment Period for employees not employed by the Corporation more than
90 days before the first business day of such Payment Period), an authorization
stating the initial percentage to be deducted from the employee's pay and
authorizing the purchase of shares of Common Stock for the employee in each
Payment Period in accordance with the terms of the 1996 Purchase Plan.
 
     Unless an employee files a new authorization or withdraws from the 1996
Purchase Plan, the deductions and purchases under the authorization the employee
has on file under the 1996 Purchase Plan will continue from the initial Payment
Period to succeeding Payment Periods as long as the 1996 Purchase Plan remains
in effect. Deductions may be increased or decreased during a Payment Period, as
set forth above.
 
     An employee may withdraw from the 1996 Purchase Plan, in whole but not in
part, at any time prior to the last business day of each Payment Period by
delivering a withdrawal notice to the Corporation, in which event the
Corporation will refund the entire balance of the employee's deductions not
previously used to purchase stock under the 1996 Purchase Plan.
 
     If an employee is not a participant in the 1996 Purchase Plan on the last
day of the Payment Period, the employee generally is not entitled to exercise
his option. An employee's rights under the 1996 Purchase Plan generally
terminate upon his voluntary withdrawal from the 1996 Purchase Plan at any time,
or when he ceases employment because of retirement, resignation, discharge,
death, change of status or any other reason, except that if an employee is
laid-off on account of an absence from work during the last three months of any
Payment Period, he is nevertheless deemed to be a participant in the 1996
Purchase Plan on the last day of the Payment Period. Notwithstanding any other
provision herein, if a participant's employment is terminated by reason of
retirement, and the date of such termination occurs after the date that is three
months prior to the last day of the Payment Period, such participant's rights
under the 1996 Purchase Plan are not immediately terminated, and if the
participant has not withdrawn from the 1996 Purchase Plan, such participant's
options shall be deemed to have been exercised on the last day of the Payment
Period in accordance with the terms of the Plan.
 
     An employee's rights under the 1996 Purchase Plan are the employee's alone
and may not be transferred to, assigned to, or availed of by, any other person.
Any option granted to an employee may be exercised, during the employee's
lifetime, only by the employee.
 
     The proceeds received by the Corporation from the sale of Common Stock
pursuant to the 1996 Purchase Plan will be used for general corporate purposes.
The Corporation's obligation to deliver shares of Common Stock is subject to the
approval of any governmental authority required in connection with the sale or
issuance of such shares.
                                       18
<PAGE>   21
 
     The following general rules are currently applicable for United States
federal income tax purposes upon the grant and exercise of options to purchase
shares of Common Stock pursuant to the 1996 Purchase Plan:
 
          1. The amounts deducted from an employee's pay under the 1996 Purchase
     Plan will be included in the employee's compensation subject to federal
     income tax. In general, no additional income will be recognized by the
     employee either at the time options are granted pursuant to the 1996
     Purchase Plan or at the time the employee purchases shares pursuant to the
     1996 Purchase Plan.
 
          2. If the employee disposes of shares of Common Stock more than two
     years after the first business day of the Payment Period in which the
     employee acquired the shares (or the first business day of the portion of a
     Payment Period beginning July 1, in the case of employees who participate
     in the 1996 Purchase Plan effective July 1 of that Payment Period), then
     upon such disposition the employee will recognize compensation income in an
     amount equal to the lesser of:
 
             (a) the excess, if any, of the fair market value of the shares on
        the date of disposition over the amount the employee paid for the
        shares, or
 
             (b) approximately 15% of the fair market value of the shares on the
        first business day of the Payment Period (or the first business day of
        the portion of a Payment Period beginning July 1, in the case of
        employees who participate in the 1996 Purchase Plan effective July 1 of
        that Payment Period.
 
          In addition, the employee generally will recognize capital gain or
     loss in an amount equal to the difference between the amount realized upon
     the sale of shares and the employee's tax basis in the shares (i.e., the
     amount the employee paid for the shares plus the amount, if any, taxed as
     compensation income). If the employee's holding period for the shares
     exceeds one year, such gain or loss will be long-term capital gain or loss.
     If the employee's holding period for the shares exceeds 18 months, the
     employee may be entitled to a reduced long-term capital gains rate.
 
          3. If the employee disposes of shares of Common Stock within two years
     after the first business day of the Payment Period in which the employee
     acquired the shares (or the first business day of the portion of a Payment
     Period beginning July 1, in the case of employees who participate in the
     1996 Purchase Plan effective July 1 of that Payment Period), then upon
     disposition the employee will recognize compensation income in an amount
     equal to the excess of the fair market value of the shares on the last
     business day of the applicable Payment Period over the amount the employee
     paid for the shares.
 
          In addition, the employee generally will recognize capital gain or
     loss in an amount equal to the difference between the amount realized upon
     the sale of the shares and the employee's tax basis in the shares (i.e.,
     the amount the employee paid for the shares plus the amount, if any, taxed
     to the employee as compensation income). If the employee's holding period
     for the shares is more than one year, such gain or loss will be long-term
     capital gain or loss. If the employee's holding period for the shares
     exceeds 18 months, the employee may be entitled to a reduced long-term
     capital gains rate.
 
          4. If the two-year holding period is satisfied with respect to Common
     Stock issued upon exercise of an option, the Corporation will not be
     entitled to a tax deduction with respect to such option or the issuance of
     shares of Common Stock upon exercise of such option. If the two-year
     holding period is not satisfied with respect to Common Stock issued upon
     exercise of an option, the Corporation generally will be entitled to a tax
     deduction equal to the amount of compensation income taxable to the
     employee upon disposition of such Common Stock.
 
     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENT TO
THE CORPORATION'S 1996 PURCHASE PLAN.

                     RATIFICATION OF SELECTION OF AUDITORS
 
     The Board of Directors has selected the firm of Coopers & Lybrand L.L.P.,
independent certified public accountants, to serve as auditors for the fiscal
year ending December 31, 1998. Coopers & Lybrand L.L.P. has served as the
Corporation's auditors since 1968. It is expected that a member of the firm will
be present at the Annual Meeting of Shareholders with the opportunity to make a
statement if so desired and will be available to respond to appropriate
questions.
 
     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THIS
SELECTION.
 
                             SHAREHOLDER PROPOSALS
 
     Proposals of shareholders intended for inclusion in the proxy statement to
be furnished to all shareholders entitled to vote at the next annual meeting of
the Corporation must be received at the Corporation's principal executive
offices not later than January 15, 1999. In order to minimize controversy as to
the date on which a proposal was received by the Corporation, it is suggested
that proponents submit their proposals by Certified Mail -- Return Receipt
Requested.
 
                           EXPENSES AND SOLICITATION
 
     The cost of solicitation of proxies will be borne by the Corporation, and
in addition to soliciting shareholders by mail through its regular employees,
the Corporation may request banks and brokers to solicit their customers who
have stock of the Corporation registered in the names of a nominee and, if so,
will reimburse such banks and brokers for their reasonable out-of-pocket costs.
Solicitation by officers and employees of the Corporation may also be made of
some shareholders in person or by mail, telephone or telegraph following the
original solicitation.

                                 TERADYNE, INC.

                        1996 EMPLOYEE STOCK PURCHASE PLAN


ARTICLE 1 - PURPOSE

         This Employee Stock Purchase Plan (the "Plan") is intended as an
incentive and to encourage stock ownership by all eligible employees of
Teradyne, Inc. (the "Company"), participating subsidiaries, and acquired
businesses so that they may share in the growth of the Company by acquiring or
increasing their proprietary interest in the Company. It is intended that
options issued pursuant to the Plan shall constitute options issued pursuant to
an "employee stock purchase plan" within the meaning of Section 423 of the
Internal Revenue Code of 1986 (the "Code"), as amended.

ARTICLE 2 - ADMINISTRATION OF THE PLAN

         The Plan may be administered by a committee appointed by the Board of
Directors of the Company (the "Committee"). The Committee shall consist of not
less than two members of the Company's Board of Directors. The Board of
Directors may from time to time remove members from, or add members to, the
Committee. Vacancies on the Committee, howsoever caused, shall be filled by the
Board of Directors. The Committee may select one of its members as Chairman, and
shall hold meetings at such times and places as it may determine. Acts by a
majority of the Committee, or acts reduced to or approved in writing by a
majority of the members of the Committee, shall be the valid acts of the
Committee.

         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 of Directors. The Committee may from time to time adopt
such rules and regulations for carrying out the Plan as it may deem best,
provided that any such rules and regulations shall be applied on a uniform basis
to all employees under the Plan. No member of the Board of Directors 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.

         In the event the Board of Directors fails to appoint or refrains from
appointing a Committee, the Board of Directors shall have all powers and
authority to administer the Plan. In such event, the word "Committee" wherever
used herein shall be deemed to mean the Board of Directors.

ARTICLE 3 - ELIGIBLE EMPLOYEES

         No option may be granted to any person serving as a member of the
Committee at the time of grant. Subject to this limitation, all Eligible
Employees (as defined herein) of the Company or any of its participating
subsidiaries (as defined in Article 18) who have completed more than 90 days of
employment with the Company or any of its subsidiaries on or before the first
day of any Payment Period (as defined in Article 5) shall be eligible
<PAGE>   24
                                      -2-

to receive options under this Plan to purchase the Company's Common Stock, and
all Eligible Employees shall have the same rights and privileges as defined in
this Plan. In no event may an employee be granted an option if such employee,
immediately after the option is granted, owns stock possessing 5 percent or more
of the total combined voting power or value of all classes of stock of the
Company or of its parent corporation or subsidiary corporation, as the terms
"parent corporation" and "subsidiary corporation" are defined in Section 425 of
the Code. For purposes of determining stock ownership under this paragraph, the
rules of Section 425(d) of the Code shall apply, and stock which the employee
may purchase under outstanding options shall be treated as stock owned by the
employee.

         For purposes of this Plan the term "Eligible Employee", shall not
include an employee whose customary employment is less than 20 hours per week or
whose customary employment is for not more than 5 months in any calendar year.

         The Board of Directors shall have the authority to permit employees of
acquired businesses to participate in the Plan effective within the then current
Payment Period without compliance with the eligibility and participation
requirements of the Plan, to the extent permitted by the Code.

ARTICLE 4 - STOCK SUBJECT TO THE PLAN

         The stock subject to the options shall be shares of the Company's
authorized but unissued shares of Common Stock or shares of Common Stock
re-acquired by the Company, including shares purchased in the open market. The
aggregate number of shares which may be issued pursuant to the Plan is
700,000, subject to adjustment as provided in Article 13. In the event 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 under the Plan.

ARTICLE 5 - PAYMENT PERIOD AND STOCK OPTIONS

         The twelve-month period commencing annually on the first day of January
and ending annually on the last day of December is the Payment Period during
which payroll deductions will be accumulated under the Plan. Each Payment Period
includes only regular pay days falling within it.

         Annually on the first business day of the Payment Period, the Company
will grant to each Eligible Employee who has elected to participate in the Plan
an option to purchase on the last day of such Payment Period, at the Option
Price hereinafter provided for, such number of shares of the Common Stock of the
Company reserved for the purpose of the Plan as does not exceed the greater of
the number of shares equal to 10% of the employee's regular annual base pay
divided by the price determined in accordance with (i) below, or 3,000 shares,
on condition that such employee remains eligible to participate in the Plan
throughout such Payment Period. The participant shall be entitled to exercise
such options so granted only to the extent of his accumulated payroll deductions
on the last day of such Payment Period, but in no event to exceed 3,000 shares.
The Option Price for each Payment Period shall be the lesser of (i) 85% of the
<PAGE>   25
average market price of the Company's Common Stock on the first business day of
the Payment Period or (ii) 85% of the average market price of the Company's
Common Stock on the last business day of the Payment Period, in either event
rounded up to avoid fractions other than 1/4, 1/2 and 3/4. The foregoing
limitation on the number of shares which may be granted in any Payment Period
and the Option Price per share shall be subject to adjustment as provided in
Article 13.

         For purposes of the Plan the term "average market price" is the average
of the high and low prices of the Common Stock of the Company on the principal
national securities exchange on which it is so traded or such other national
securities exchange as shall be designated by the Committee.

         For purposes of this Plan the term "business day" as used herein means
a day on which there is trading on the national securities exchange.

         No Eligible Employee shall be granted an option which permits his
rights to purchase Common Stock under the Plan and any similar plans of the
Company or any parent or subsidiary corporations to accrue at a rate which
exceeds $25,000 of fair market value of such stock (determined at the time such
option is granted) for each calendar year in which such option is outstanding at
any time. The purpose of the limitation in the preceding sentence is to comply
with Section 423(b)(8) of the Code.

ARTICLE 6 - EXERCISE OF OPTION

         Each Eligible Employee who continues to be a participant in the Plan on
the last business day of a Payment Period shall be deemed to have exercised his
option on such date and shall be deemed to have purchased from the Company such
number of full shares of Common Stock reserved for the purpose of the Plan as
his accumulated payroll deductions on such date will pay for at such Option
Price but in no event more than 3,000 shares. Subject to Article 15, if a
participant is not an employee on the last business day of a Payment Period, he
shall not be entitled to exercise his option.

ARTICLE 7 - UNUSED PAYROLL DEDUCTIONS

         Only full shares of Common Stock may be purchased under the Plan.
Unused payroll deductions remaining in an employee's account at the end of a
Payment Period shall be refunded to such participant without interest.

ARTICLE 8 - AUTHORIZATION FOR ENTERING PLAN

         An Eligible Employee may enter the Plan by filling out, signing and
delivering to the Personnel Office an authorization:

         A.       Stating the amount to be deducted regularly from his pay;
<PAGE>   26
                                      -4-

         B.       Authorizing the purchase of stock for him in the Payment
                  Period in accordance with the terms of the Plan; and

         C.       Specifying the exact name in which stock purchased for him is
                  to be issued as provided under Article 12 hereof.

Such authorization must be received by the Personnel Office at least 15 days
before the beginning date of the next Payment Period.

         Unless an employee files a new authorization or withdraws from the
Plan, his deductions and purchases under the authorization he has on file under
the Plan will continue from one Payment Period to succeeding Payment Periods as
long as the Plan remains in effect.

         The Company will accumulate and hold for the employee's account the
amounts deducted from his pay. No interest will be paid on it.

ARTICLE 9 - MINIMUM AND MAXIMUM AMOUNTS OF PAYROLL DEDUCTIONS

         An Eligible Employee may authorize payroll deductions in an amount (in
whole percents) not less than 2% but not more than 10% of his regular annual
base pay.

ARTICLE 10 - NO CHANGE IN PAYROLL DEDUCTIONS

         Deductions may not be increased or decreased during any Payment Period,
except to reflect changes in base pay during the Payment Period.

ARTICLE 11 - WITHDRAWAL FROM THE PLAN

         An Eligible Employee may withdraw from the Plan, in whole but not in
part, at any time prior to the last business day of each Payment Period by
delivering a Withdrawal Notice to the Personnel Office, in which event the
Company will refund the entire balance of his deductions as soon as practicable
thereafter.

         To re-enter the Plan, an Eligible Employee who has previously withdrawn
must file a new authorization in accordance with Article 8. His re-entry into
the Plan cannot, however, become effective before the beginning of the next
Payment Period following his withdrawal.

ARTICLE 12 - ISSUANCE OF STOCK

         Certificates for stock issued to participants will be delivered as soon
as practicable after each Payment Period.

         Stock purchased under the Plan will be issued only in the name of the
Eligible Employee, or if his authorization so specifies, in the name of the
employee and another person of legal age as joint tenants with rights of
survivorship.
<PAGE>   27
ARTICLE 13 - ADJUSTMENTS

         Upon the happening of any of the following described events, an
optionee's rights under options granted hereunder shall be adjusted as
hereinafter provided:

         A. In the event shares of Common Stock of the Company shall be
         subdivided or combined into a greater or smaller number of shares or
         if, upon a merger, consolidation, reorganization, split-up,
         liquidation, combination, recapitalization or the like of the Company,
         the shares of the Company's Common Stock shall be exchanged for other
         securities of the Company or of another corporation, each optionee
         shall be entitled, subject to the conditions herein stated, to purchase
         such number of shares of Common Stock or amount of other securities of
         the Company or such other corporation as were exchangeable for the
         number of shares of Common Stock of the Company which such optionee
         would have been entitled to purchase except for such action, and
         appropriate adjustments shall be made in the purchase price per share
         to reflect such subdivision, combination, or exchange; and

         B. In the event the Company shall issue any of its shares as a stock
         dividend upon or with respect to the shares of stock of the class which
         shall at the time be subject to option hereunder, each optionee upon
         exercising such an option shall be entitled to receive (for the
         purchase price paid upon such exercise) the shares as to which he is
         exercising his option and, in addition thereto (at no additional cost),
         such number of shares of the class or classes in which such stock
         dividend or dividends were declared or paid, and such amount of cash in
         lieu of fractional shares, as is equal to the number of shares thereof
         and the amount of cash in lieu of fractional shares, respectively,
         which he would have received if he had been the holder of the shares as
         to which he is exercising his option at all times between the date of
         the granting of such option and the date of its exercise.

         Upon the happening of any of the foregoing events, the class and
aggregate number of shares set forth in Article 4 hereof which are subject to
options which have heretofore been or may hereafter be granted under the Plan
shall also be appropriately adjusted to reflect the events specified in
paragraphs A and B above. The Committee shall determine the adjustments to be
made under this Article 13, and its determination shall be conclusive.

ARTICLE 14 - NO TRANSFER OR ASSIGNMENT OF EMPLOYEE'S RIGHTS

         An employee's rights under the Plan are his alone and may not be
transferred or assigned to, or availed of by, any other person. Any option
granted to an employee may be exercised only by him.

ARTICLE 15 - TERMINATION OF EMPLOYEE'S RIGHTS

         An employee's rights under the Plan will terminate when he ceases to be
an employee because of retirement, resignation, discharge, death, change of
status or for any other reason, 
<PAGE>   28

except that if an employee is laid off on account of an absence of work during
the last three months of any Payment Period, he shall nevertheless be deemed to
be a participant in the Plan on the last day of the Payment Period. A Withdrawal
Notice will be considered as having been received from the employee on the day
his employment ceases, and all payroll deductions not used to purchase stock
will be refunded.

         If an employee's payroll deductions are interrupted by any legal
process, a Withdrawal Notice will be considered as having been received from him
on the day the interruption occurs.

ARTICLE 16 - TERMINATION AND AMENDMENTS TO PLAN

         The Plan may be terminated at any time by the Company's Board of
Directors but such termination shall not affect options then outstanding under
the Plan. It will terminate in any case when all or substantially all of the
unissued shares of stock reserved for the purposes of the Plan have been
purchased. If at any time shares of stock reserved for the purposes of the Plan
remain available for purchase but not in sufficient number to satisfy all then
unfilled purchase requirements, the available shares shall be apportioned among
participants in proportion to their options and the Plan shall terminate. Upon
such termination or any other termination of the Plan, all payroll deductions
not used to purchase stock will be refunded.

         The Board of Directors also reserves the right to amend the Plan from
time to time in any respect provided, however, that no amendment shall be
effective without prior approval of the stockholders which would (a) except as
provided in Article 13, increase the number of shares of Common Stock to be
offered under the Plan or (b) change the class of employees eligible to receive
options under the Plan.

ARTICLE 17 - LIMITATIONS ON SALE OF STOCK PURCHASED UNDER THE PLAN

         The Plan is intended to provide Common Stock for investment and not for
resale. The Company does not, however, intend to restrict or influence any
employee in the conduct of his own affairs. An employee may, therefore, sell
stock purchased under the Plan at any time he chooses, subject to compliance
with any applicable, Federal or state securities laws; provided, however, that
because of certain Federal tax requirements, each employee will agree by
entering the Plan, promptly to give the Company notice of any such stock
disposed of within two years after the date of grant of the applicable option
showing the number of such share disposed of. THE EMPLOYEE ASSUMES THE RISK OF
ANY MARKET FLUCTUATIONS IN THE PRICE OF THE STOCK.

ARTICLE 18 - PARTICIPATING SUBSIDIARIES

         The term "participating subsidiaries" shall mean any subsidiary of the
Company which is designated by the Committee to participate in the Plan. The
Committee shall have the power to make such designation before or after the Plan
is approved by the stockholders.

ARTICLE 19 - OPTIONEES NOT STOCKHOLDERS

         Neither the granting of an option to an employee nor the deductions
from his pay shall constitute such employee a stockholder of the shares covered
by an option until such shares have been purchased by and issued to him.

ARTICLE 20 - APPLICATION OF FUNDS

         The proceeds received by the Company from the sale of Common Stock
pursuant to options granted under the Plan will be used for general corporate
purposes.

ARTICLE 21 - GOVERNMENTAL REGULATION

         The Company's obligation to sell and deliver shares of the Company's
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.

ARTICLE 22 - APPROVAL OF STOCKHOLDERS

         The Plan shall not take effect until approved by the holders of a
majority of the outstanding shares of the Common Stock of the Company, which
approval must occur within the period ending twelve months after the date the
plan was adopted by the Board of Directors. The Plan was adopted by the Board of
Directors on March 19, 1996. It was approved by the stockholders of the
Company on May 23, 1996. All subsequent amendments to the Plan adopted by the
Board of Directors have been approved by the stockholders.
