                                PROXY STATEMENT
 
                                 APRIL 18, 1995
 
     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 23, 1996, at
10:00 A.M., at The First National Bank of Boston, 100 Federal Street (First
Floor), Boston, Massachusetts.
 
     Only shareholders of record as of the close of business on April 5, 1996
(the "Record Date"), will be entitled to vote at the Annual Meeting and any
adjournments thereof. As of the Record Date,           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 amend the Corporation's Restated Articles of
Organization to increase the amount of the Corporation's authorized Common
Stock, par value $.125 per share, from 125,000,000 to 250,000,000 shares, (ii)
to amend the 1991 Employee Stock Option Plan by increasing the aggregate number
of shares of Common Stock which may be issued pursuant to said plan by 3,000,000
shares, (iii) to approve the adoption of the 1996 Stock Purchase Plan, and (iv)
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, other than matter number two
involving the proposed amendment to the Company's Restated Articles of
Organization, an affirmative vote of at least a majority of the shares present,
or represented, and entitled to vote at the meeting is required for approval.
Approval of the Amendment to the Corporation's Restated Articles of Organization
to increase the number of authorized shares of Common Stock will require the
affirmative vote of at least a majority of all outstanding shares of the
Corporation's Common Stock. An

<PAGE>   4
 
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, 1995, 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 18, 1996.
 
                             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 I expires at the Annual Meeting. The nominees for election as Class I
directors are Messrs. d'Arbeloff, Artzt, Bagley and Gregory, each of whom,
except for Mr. Bagley, was elected at the Annual Meeting of Shareholders held
May 27, 1993. Mr. Bagley was appointed to the Board of Directors by the Board on
January 31, 1996. If re-elected, the Class I nominees will hold office until the
Annual Meeting of Shareholders to be held in 1999, 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 I
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.


<TABLE>
 
     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 elected a director, the principal occupation of each of the nominees and

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. See also "1987 Non-Employee Director Stock Option Plan."
 
1987 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN
 
     The 1987 Non-Employee Director Stock Option Plan (the "1987 Plan") was
adopted by the Board of Directors of the Corporation on March 12, 1987 and
approved by the shareholders on May 8, 1987. The 1987 Plan is administered by
the Compensation Committee. However, the time of grant, number of shares
granted, exercise price and vesting schedule are established by the terms of the
1987 Plan and are not subject to the discretion of the Compensation Committee or
any person. Only non-employee directors may participate in the 1987 Plan.
 
     Under the 1987 Plan, all new non-employee directors elected after January
1, 1992 receive an automatic grant of an option to purchase 20,000 shares of
Common Stock. An additional annual grant of 10,000 shares is automatically made
to each non-employee director on the date of the first meeting of the Board of
Directors in each year. All options are non-statutory stock options, have an
exercise price equal to the fair market value on the date of grant, vest
annually at the rate of 25% and have a term of five years. Unless terminated
sooner, the 1987 Plan will terminate on March 12, 1997.

Common Stock, subject to adjustment for capital changes. On December 31, 1995,
options to purchase 247,500 shares of the Corporation's Common Stock under the
1987 Plan were outstanding at a weighted average exercise price of $11.44.

(1) Stock options were granted under the Corporation's 1991 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.
Alexander d'Arbeloff, Robbins, Prestridge, Chamillard, George d'Arbeloff 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.

<TABLE>
 
     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
 
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 composed entirely of non-employee directors.
The Compensation Committee is responsible for developing and making
recommendations to the Board of Directors with respect to the Corporation's
compensation policies. In addition, the Compensation Committee, pursuant to
authority delegated by the Board of Directors, determines on an annual basis the
compensation to be paid and stock option awards to be made to each of the
executive officers.
 
     The Compensation Committee's executive compensation policies are designed
to provide competitive levels of compensation that assist the Corporation in
attracting and retaining qualified executives. In setting 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
 
                                       10

<PAGE>   13
 
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 executive
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   herein. The model compensation amount is
consistent with the Corporation's internal compensation structure.
 
     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 groups versus goal; and
 
          (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 100% 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 1995, 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 a particular 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
financial results for the year were consistent with the Corporation achieving
its mid-term business plan; and (4) whether each group was in a stronger
strategic position at the end of the year than at the beginning. 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 1995, total cash compensation for all executive officers
from the Corporation's Cash Compensation Plan ranged from 11% above model
compensation to 25% above model compensation.
 
                                       11

<PAGE>   14
 
     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
Compensation 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 Compensation 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. d'Arbeloff's cash compensation for 1995 awarded under the Corporation's
Cash Compensation Plan was $672,630, which is approximately 25.55% more than Mr.
d'Arbeloff's 1995 model compensation of $535,719. Mr. d'Arbeloff's 1995 cash
compensation awarded pursuant to the Corporation's Cash Compensation Plan is a
5.23% increase over his 1994 cash compensation. Mr. d'Arbeloff's fixed salary
amount was $307,532 for 1995 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.
d'Arbeloff's Variable Compensation payout was $365,098 for 1995. Mr.
d'Arbeloff'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. d'Arbeloff also
received cash compensation in the amount of $84,577 in 1995 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 generally made to all employees of the Corporation on an equal
basis.
 
     The stock options granted to Mr. d'Arbeloff during fiscal 1995 are
consistent with the design of the overall program and are shown in the Summary
Compensation Table above. Mr. d'Arbeloff's 80,000 shares, which represented
3.09% of the total option shares awarded to all employees during fiscal 1995,
placed him at the median of the external surveys. In assessing Mr. d'Arbeloff's
individual performance for the year for purposes of his stock option awards, the
Compensation Committee concluded that, on balance, Mr. d'Arbeloff 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. Artzt, Hibbard and Testa comprised the Compensation Committee for
fiscal year 1995. Mr. Bagley was added to the Compensation Committee in January
1996. See Certain Relationships and Related Transactions. Richard J. Testa is a
member of the law firm Testa, Hurwitz & Thibeault in Boston, Massachusetts. Such
law firm served as general counsel for the Corporation during the fiscal year
1995 and the Corporation expects to retain the services of such firm for the
fiscal year 1996.
 
COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(M)
 
     Section 162(m) of the Internal Revenue Code of 1986, as amended ("Section
162(m)"), generally disallows a tax deduction to the Corporation for
compensation over $1 million paid to the Corporation's Chief Executive Officer
and the other executive officers named in the Summary Compensation Table.
Qualifying performance-based compensation, however, will not be subject to the
deduction limit if certain requirements are met. The Board of Directors has
formed a Stock Option Committee to administer the Corporation's stock plans in
response to Section 162(m) and has, subject to shareholder approval, amended the
Corporation's 1991 Employee Stock Option Plan to permit grants under such plan
to comply with Section 162(m).
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     On December 1, 1995, the Corporation completed its acquisition of Megatest
Corporation, a Delaware corporation ("Megatest"), by means of a merger (the
"Merger") of M Merger Corp., a Delaware corporation and wholly owned subsidiary
of the Corporation ("Merger Sub"), with and into Megatest, pursuant to the
Agreement and Plan of Merger and Reorganization, dated as of September 5, 1995,
as amended (the "Merger Agreement"), by and among the Corporation, Merger Sub
and Megatest. As a result of the Merger, Megatest became a wholly owned
subsidiary of the Corporation.
 
     Pursuant to terms of the Merger Agreement, upon the effective time of the
Merger, each outstanding share of Megatest common stock, $.001 par value
("Megatest Common Stock"), was converted into the right to receive 0.9091 shares
of the Corporation's common stock, $.125 par value ("Teradyne Common Stock")
(subject to payment of cash in lieu of any fractional shares). As a result of
the Merger, the former stockholders of Megatest received approximately 6.8
million shares of Teradyne Common Stock. Each holder of Megatest Common Stock
received cash in lieu of any fractional share, equal to such fraction multiplied
by $29.11 (the "Final Teradyne Stock Price"), which is the average of the
closing prices of Teradyne Common Stock for the twenty consecutive days on which
Teradyne Common Stock was traded on The New York Stock Exchange ending on
November 24, 1995. Mr. James W. Bagley served as a member of the Board of
Directors of Megatest at the time of the Merger. Mr. John E. Halter served as
President and Chief Executive Officer of Megatest at the time of the Merger. Mr.
Bagley is currently a member of the Corporation's Board of Directors. Mr. Halter
is currently an executive officer of the Corporation. At the time of the Merger,
Mr. Bagley and Mr. Halter held 11,000 and 138,939 shares respectively of
Megatest Common Stock.
 
     The terms of this transaction and the consideration received by Megatest's
stockholders were the result of arm's-length negotiations between the
representatives of the Corporation and Megatest and took into account various
factors concerning the relative valuations of the businesses and the common
stock of the Corporation and Megatest.

            PROPOSAL TO AMEND THE RESTATED ARTICLES OF ORGANIZATION
 
     The Board of Directors has voted to recommend to the shareholders that the
Corporation amend the Corporation's Restated Articles of Organization to
increase the number of authorized shares of Common Stock, par value $.125 per
share, from 125,000,000 shares to 250,000,000 shares (the "Amendment").
 
     If the Amendment is approved and after giving effect to shares reserved for
issuance under the Corporation's stock plans, the Board of Directors will have
the authority to issue      (as of April 5, 1996)
 
                                       14

<PAGE>   17
 
shares of Common Stock without further shareholder approval. The Board of
Directors of the Corporation believes that the increase in the number of
authorized shares of Common Stock is in the best interests of the Corporation
and its shareholders. The Board of Directors believes that the authorized number
of shares of Common Stock should be increased to provide sufficient shares for
such corporate purposes as may be determined by the Board of Directors to be
necessary or desirable, which may include, without limitation, facilitating
broader ownership of the Corporation's Common Stock by effecting a stock split
or issuing a stock dividend, raising capital or acquiring property through the
sale of stock, or attracting or retaining valuable employees by the issuance of
stock options. The Corporation at present has no commitments, agreements or
undertakings obligating the Corporation to issue any such additional shares
(other than pursuant to the Rights Agreement dated as of March 14, 1990);
however, the Board of Directors considers the authorization of additional shares
of Common Stock advisable to ensure prompt availability of shares for issuance
should the occasion arise.
 
     Under Massachusetts law, the Board of Directors generally may issue
authorized but unissued shares of Common Stock without shareholder approval. The
Board of Directors does not currently intend to seek shareholder approval prior
to any future issuance of additional shares of Common Stock, unless shareholder
action is required in a specific case by applicable law, the rules of any
exchange or market on which the Corporation's securities may then be listed, or
the articles of organization or by-laws of the Corporation then in effect.
Frequently, opportunities arise that require prompt action, and the Corporation
believes that the delay necessitated for shareholder approval of a specific
issuance could be to the detriment of the Corporation and its shareholders.
 
     The additional shares of Common Stock authorized for issuance pursuant to
the Amendment will have all the rights and privileges which the presently
outstanding shares of Common Stock possess. The increase in authorized shares
would not affect the terms or rights of holders of existing shares of Common
Stock. All outstanding shares would continue to have one vote per share on all
matters to be voted on by the shareholders, including the election of directors.
 
     The authorized but unissued shares of Common Stock could be used to make a
change in control of the Corporation more difficult. For example, such shares
could be sold to purchasers who might side with the Board of Directors in
opposing a takeover bid that the Board determines not to be in the best
interests of the Corporation and its shareholders. Such a sale could have the
effect of discouraging an attempt by another person or entity, through the
acquisition of a substantial number of shares of the Corporation's Common Stock,
to acquire control of the Corporation, since the issuance of new shares could be
used to dilute the stock ownership of such person or entity. The Corporation is
not aware, however, of any pending or threatened efforts to obtain control of
the Corporation.
 
     Approval of the Amendment to increase the number of authorized shares of
Common Stock will require the affirmative vote of at least a majority of all
outstanding shares of the Corporation's Common Stock. THE BOARD OF DIRECTORS
RECOMMENDS A VOTE FOR THE APPROVAL OF THE AMENDMENT.
 
             PROPOSAL TO AMEND THE 1991 EMPLOYEE STOCK OPTION PLAN
 
DESCRIPTION OF 1991 EMPLOYEE STOCK OPTION PLAN
 
     The Board of Directors has proposed to amend the 1991 Employee Stock Option
Plan (the "1991 Plan") (i) to increase the number of shares of Common Stock
which may be issued pursuant to said plan by 3,000,000 shares and (ii) to permit
grants thereunder to comply with Section 162(m) of the Internal Revenue Code of
1986. The 1991 Plan was adopted by the Board of Directors on March 13, 1991, and
approved by the shareholders on April 26, 1991. Under the 1991 Plan both
incentive stock options ("ISOs"), as that term is
 
                                       15

<PAGE>   18
 
defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), and non-statutory stock options ("NSOs") are available for grant. The
1991 Plan provides that ISOs to purchase Common Stock of the Corporation may be
granted to any employee of the Corporation and its subsidiaries and NSOs to
purchase Common Stock of the Corporation may be granted to any employee,
consultant or director of the Corporation and its subsidiaries. Directors who
are not also officers or employees are not eligible to receive options under the
1991 Plan. The 1991 Plan presently authorizes the issuance of a maximum of
12,000,000 shares of Common Stock, subject to adjustment for capital changes.
 
     The 1991 Plan is administered by the Stock Option Committee, which is
authorized to determine the individuals to receive options, the number of shares
subject to each option, whether the option shall be exercisable in full at the
time of grant or in installments, and other pertinent terms and provisions,
including the exercise price. The Stock Option Committee specifies at the time
of grant of an option under the 1991 Plan whether or nor such option will be an
ISO under the Code. To date, all of the options granted pursuant to the 1991
Plan have been NSOs. Although the 1991 Plan currently has no limitation on the
number of shares that may be optioned to any one person, the proposed amendment
would limit to 150,000 the number of shares for which grants of ISOs and NSOs
may be made to any employee per year. The term of each option may be for a
period not exceeding ten years and one day from the date of grant in the case of
NSOs, and ten years from the date of grant in the case of ISOs generally (or
five years for ISOs granted to employees holding 10% or more of the total
combined voting power of all classes of the stock of the Corporation or any
subsidiary). Options may not be assigned or transferred except by will or by
operation of the laws of descent and distribution. Payment for exercise of an
option under the 1991 Plan may be made in whole or in part in installments or by
tendering Common Stock of the Corporation if authorized by the instrument
granting the option. The 1991 Plan contains terms providing for the exercise of
options by or on behalf of former and deceased employees, respectively.
 
     The 1991 Plan contains terms and conditions relating to ISOs necessary to
comply with the provisions of Section 422 of the Code.
 
     Option holders are protected against dilution in the event of a stock
dividend, recapitalization, stock split or similar transaction. The Board of
Directors may from time to time adopt amendments, certain of which are subject
to shareholder approval, and may terminate the 1991 Plan at any time (although
such action shall not affect options previously granted). Any shares subject to
an option which for any reason expires or terminates unexercised may again be
available for option grants under the 1991 Plan. Unless terminated sooner, the
1991 Plan will terminate on March 13, 2001.
 
     As of March 31, 1996, options to purchase      shares of Common Stock were
outstanding and     shares of Common Stock were available under the 1991 Plan 
for additional option grants. As of April   , 1996, the market value of the 
shares of Common Stock subject to options under the 1991 Plan was $       .
 
FEDERAL INCOME TAX CONSEQUENCES
 
     A. Incentive Stock Options.  The following general rules are applicable for
Federal income tax purposes under existing law to employees who receive and
exercise ISOs granted under the 1991 Plan;
 
          1. Generally, no taxable income results to the optionee upon the grant
     of an ISO or upon the issuance of shares to him or her upon exercise of the
     ISO.
 
          2. No federal income tax deduction is allowed to the Corporation upon
     either grant or exercise of an ISO under the 1991 Plan.
 
          3. If shares acquired upon exercise of an ISO are not disposed of on
     or before the later of (i) two years following the date the ISO was granted
     or (ii) one year following the date the shares are transferred
 
                                       16

<PAGE>   19
 
     to the optionee pursuant to the ISO exercise (the "Holding Periods"), the
     difference between the amount realized on any subsequent disposition of the
     shares and the exercise price will be treated as long-term capital gain or
     loss to the optionee.
 
          4. If shares acquired upon exercise of an ISO are disposed of on or
     before the expiration of one or both of the requisite Holding Periods (a
     "Disqualifying Disposition"), then in most cases the lesser of (i) any
     excess of the fair market value of the shares at the time of exercise of
     the ISO over the exercise price or (ii) the actual gain on disposition,
     will be treated as compensation to the optionee and will be taxed as
     ordinary income in the year of such disposition.
 
          5. In any year that an optionee recognizes compensation income on a
     Disqualifying Disposition of stock acquired by exercising an ISO, the
     Corporation generally will be entitled to a corresponding deduction for
     federal income tax purposes .
 
          6. Any excess of the amount realized by the optionee as the result of
     a Disqualifying Disposition over the sum of (i) the exercise price and (ii)
     the amount of ordinary income recognized under the above rules will be
     treated as capital gain.
 
          7. Capital gain or loss recognized on disposition of shares will be
     long-term capital gain or loss if the optionee's holding period for the
     shares exceeds one year.
 
          8. Payment for shares acquired upon exercise of an ISO ("option
     stock") may in some cases be made by delivering shares of the Corporation's
     Common Stock ('old stock"). Generally, if an optionee exchanges old stock
     for option stock instead of, or in addition to, paying cash, special rules
     will apply.
 
          9. In addition to the tax consequences described above, the exercise 
     of ISOs may result in a further "minimum tax" under the Code. The Code
     provides that an "alternative minimum tax" (at a maximum rate of 28%) will
     be applied against a taxable base which is equal to "alternative minimum
     taxable income," reduced by a statutory exemption. In general, the amount
     by which the value of the Common Stock received upon exercise of the ISO
     exceeds the exercise price is included in the optionee's alternative
     minimum taxable income. A taxpayer is required to pay the higher of his
     regular tax liability or the alternative minimum tax. A taxpayer who pays
     alternative minimum tax attributable to the exercise of an ISO may be
     entitled to a tax credit against his or her regular tax liability in later
     years.
 
     B.  Non-Statutory Stock Options.  An NSO granted under the 1991 Plan is
taxed in accordance with Section 83 of the Code and the Regulations issued
thereunder. The following general rules are applicable to holders of such
options and to the Corporation for Federal income tax purposes under existing
law:
 
          1. The optionee generally does not recognize any taxable income upon
     the grant of an NSO, and the Corporation is not allowed a federal income
     tax deduction by reason of such grant.
 
          2. The optionee generally will recognize ordinary compensation income
     at the time of exercise of the NSO in an amount equal to the excess, if
     any, of the fair market value of the shares on the date of exercise over
     the exercise price. The Corporation may be required to withhold income tax
     on this amount.
 
          3. When the optionee sells the shares acquired through the exercise of
     an NSO, he or she generally will recognize a capital gain or loss in an
     amount equal to the difference between the amount realized upon the sale of
     the shares and his or her basis in the shares (generally the exercise price
     plus the amount taxed to the optionee as a compensation income). If the
     optionee's holding period for the shares exceeds one year, the gain or loss
     will be a long-term capital gain or loss.
 
          4. In general, the Corporation will be entitled to a federal income
     tax deduction in the year in which compensation is recognized by the
     optionee.
 
                                       17

<PAGE>   20
 
          5. An optionee may be entitled to exercise a NSO by delivering shares
     of the Corporation's Common Stock ("old stock") to the Corporation in
     exchange for the Common Stock received upon exercise of the option ("NSO
     stock"), if the optionee's NSO agreement so provides. If an optionee
     exercises an NSO in such fashion, special rules will apply.
 
PROPOSED AMENDMENTS
 
     The Board of Directors has proposed to amend the 1991 Plan by increasing
the number of shares of Common Stock which may be issued pursuant to the 1991
Plan by 3,000,000 shares.
 
     Section 162(m) of the Code precludes a deduction by any publicly-held
corporation for compensation in excess of $1 million that is paid to the chief
executive officer of the corporation ("CEO") or to each of the four highest
compensated officers (other than the CEO) of the Company or its subsidiaries
(each a "covered employee"). The determination of whether an individual is a
"covered employee" is made as of the last day of each taxable year pursuant to
the executive compensation disclosure rules under the Securities Exchange Act of
1934. Compensation for this purpose includes not only cash remuneration, but
also compensation attributable to the exercise of NSOs. There is an exception
from the $1 million limitation for "performance-based compensation" that
satisfies certain requirements. The 1991 Plan currently qualifies for a
transition rule that exempts it from most of these performance-based
requirements until the earlier of several dates, among which is the date on
which there is a material modification of the 1991 Plan. A material modification
of the 1991 Plan includes the increase of the number of shares of Common Stock
authorized for issuance under the plan.
 
     It is now proposed to approve an amendment to qualify the 1991 Plan for
favorable federal income tax treatment with respect to the $1 million limitation
on the deduction for executive compensation to certain executive officers of the
Corporation under Section 162(m) of the Code. The amendment provides that the
maximum number of shares for which grants may be made to any employee of the
Corporation during any fiscal year of the Corporation shall not exceed 150,000
shares of Common Stock. The amendment also provides that the 1991 Plan shall, to
the extent required by applicable regulations, be administered by two or more
"outside directors" (as defined by applicable regulations). For this reason, the
Board of Directors of the Corporation has recently formed a Stock Option
Committee to administer the Corporation's stock plans. As a result of the
exercise of stock options, it is possible that some executives may recognize, in
a singly taxable year, total compensation for federal income tax purposes in
excess of $1 million. Management believes that this amendment is important to
preserve the federal income tax deductibility of executive compensation in
excess of $1 million to the extent that it may be attributable to the exercise
of stock options under the 1991 Plan.
 
     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSED AMENDMENTS.
 
                    PROPOSAL TO APPROVE THE ADOPTION OF THE
                       1996 EMPLOYEE STOCK PURCHASE PLAN
 
     The 1996 Employee Stock Purchase Plan (the "1996 Purchase Plan") was
adopted by the Board of Directors on March 19, 1996, subject to shareholder
approval. The complete text of the 1996 Purchase Plan is attached hereto as
APPENDIX A.
 
     The 1996 Purchase Plan is intended to provide an incentive to, and to
encourage stock ownership by, all eligible employees of the Corporation, and
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. Under the 1996
 
                                       18

<PAGE>   21
 
Purchase Plan payroll deductions are used to purchase the Corporation's Common
Stock for eligible, participating employees through the exercise of stock
options.
 
     It is intended that the 1996 Purchase Plan will constitute 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 but such termination will not affect options then outstanding
under the 1996 Purchase Plan. If at any time shares of Common Stock reserved for
the purposes 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 amount
of payroll deductions accumulated on behalf of each participant that would
otherwise be used to purchase stock, and the 1996 Purchase Plan will terminate.
Upon termination of the Plan, all payroll deductions not used to purchase Common
Stock will be refunded to 1996 Purchase Plan participants without interest.
 
     The 1996 Purchase Plan authorizes the issuance of up to 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. Deductions under the 1996 Purchase Plan generally may not be
increased and may not be decreased more than twice during the twelve-month
period commencing on the first day of January and ending annually on the last
day of December in each year (the "Payment Period") (or once during any Payment
Period with respect to July Employees). On the first business day of each
Payment Period (or on July 1 of such Payment Period for employees not employed
by the Corporation 90 days before the first business day of such 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
 
                                       19

<PAGE>   22
 
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 on July 1 of such
Payment Period for employees not employed by the Corporation 90 days before the
first business day of such Payment Period), and (ii) 85% of the fair market
value of the Common Stock on the last business day of the Payment 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.
 
     Employees of the Corporation (and participating subsidiaries on the United
States payroll) (A) 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 date that is 90
days prior to the first day of a particular Payment Period, on or before July 1
in any Payment Period, and (B) 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.
 
     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
 
                                       20

<PAGE>   23
 
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 or 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. The date of commencement of the first Payment Period
shall be July 1, 1996.
 
     The following general rules are currently applicable for United States
federal income tax purposes to employees who receive grants of options for
Common Stock and 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. Subject to certain requirements 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 (or the first
     business day of a portion of the Payment Period beginning July 1 for
     certain employees) in which the employee acquired the shares, then upon
     such disposition the employee will recognize ordinary compensation 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) the excess of the fair market value of the shares on the first
        business day of the Payment Period over the option price.
 
     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 basis in the shares (i.e., the amount the employee
paid for the shares plus the amount, if any, taxed as ordinary 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.
 
          3. If the employee disposes of shares of Common Stock within two years
     after the first business day of the Payment Period (or the first business
     day of a portion of the Payment Period beginning July 1 for certain
     employees) in which the employee acquired the shares, then upon disposition
     the employee will recognize ordinary compensation in an amount equal to the
     excess of the fair market value of the shares
 
                                       21

<PAGE>   24
 
     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 basis in the shares (i.e., the amount the employee
paid for the shares plus the amount, if any, taxed to the employee as ordinary
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.
 
          4. If the two-year holding period is satisfied, the Corporation will
     not receive any deduction for federal income tax purposes with respect to
     the options or the shares of Common Stock issued upon their exercise. If
     the two-year holding period is not satisfied, the Corporation generally
     will be entitled to a deduction in an amount equal to the amount which is
     considered ordinary compensation income to the employee, subject to general
     limitations on the deductibility of compensation.
 
     Approval of the 1996 Purchase Plan will require an affirmative vote of a
majority of the outstanding shares of Common Stock of the Corporation
represented in person or by proxy at the Annual Meeting and entitled to vote.
THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE 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, 1996. 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 December 20, 1996. 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 1996 Employee Stock Purchase Plan (the "Plan") is intended to
encourage stock ownership by all eligible employees of Teradyne, Inc. (the
"Company"), a Massachusetts corporation, and its participating subsidiaries (as
defined in Article 17) so that they may share in the growth of the Company by
acquiring or increasing their proprietary interest in the Company. The Plan is
designed to encourage eligible employees to remain in the employ of the Company
and its participating subsidiaries. The Plan is intended to constitute an
"employee stock purchase plan" within the meaning of Section 423(b) of the
Internal Revenue Code of 1986, as amended (the "Code").
 
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 power 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 the foregoing limitation, all employees of the
Company or any of its participating subsidiaries on United States payroll who
have completed more than 90 days of employment with the Company or any of its
participating subsidiaries (i) on or before the first day of any Payment Period
(as defined in Article 5) 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 twenty hours per week and more than
five months in any calendar year shall be eligible to receive options under the
Plan to purchase common stock of the Company, par value $.125 per share ("Common
Stock"). An employee eligible under this Plan solely by virtue of clause (ii) of
the preceding sentence shall be referred to herein as a "July Employee." All
eligible employees shall have the same rights and privileges hereunder. Persons
who elect to enter the Plan in accordance with Article 7 and who are eligible
employees on the first business day of any Payment Period (as defined in Article
5) (or on the first business day of July with respect to July Employees) shall
receive their options as of such day. Persons
 
                                       A-1

<PAGE>   26
 
who elect to enter the Plan in accordance with Article 7 and who become eligible
employees after any date on which options are granted under the Plan shall be
granted options on the first business day of the next succeeding Payment Period
or the first business day of July (whichever is applicable) on which options are
granted to eligible employees under the Plan. In no event, however, may an
employee be granted an option if such employee, immediately after the option was
granted, would be treated as owning stock possessing five percent or more of the
total combined voting power or value of all classes of stock of the Company or
of any parent corporation or subsidiary corporation, as the terms "parent
corporation" and "subsidiary corporation" are defined in Section 424(e) and (f)
of the Code. For purposes of determining stock ownership under this paragraph,
the rules of Section 424(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.
 
ARTICLE 4 -- STOCK SUBJECT TO THE PLAN.
 
     The stock subject to the options under the Plan shall be authorized but
unissued Common Stock, or shares of Common Stock reacquired 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 12. 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 under the Plan.
 
ARTICLE 5 -- PAYMENT PERIOD AND STOCK OPTIONS.
 
     For the duration of the Plan, the Payment Period shall be 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. Notwithstanding the
foregoing, the first Payment Period during which payroll deductions will be
accumulated under the Plan shall commence on July 1, 1996 and shall end on
December 31, 1996.
 
     On the first business day of each Payment Period (or on the first business
day of July of such Payment Period in the case of a July Employee), the Company
will grant to each eligible employee who is then a participant in the Plan an
option to purchase on the last day of such Payment Period, at the Option Price
hereinafter provided for, a maximum of 3,000 shares, on condition that such
employee remains eligible to participate in the Plan throughout the remainder of
such Payment Period. The participant shall be entitled to exercise the option so
granted only to the extent of the participant's accumulated payroll deductions
on the last day of such Payment Period. If the participant's accumulated payroll
deductions on the last day of the Payment Period would enable the participant to
purchase more than 3,000 shares except for the 3,000 share limitation, the
excess of the amount of the accumulated payroll deductions over the aggregate
purchase price of the 3,000 shares shall be promptly refunded to the participant
by the Company, without interest. The Option Price per share for each Payment
Period shall be the lesser of (i) 85% of the fair market value of the Common
Stock on the first business day of the Payment Period (or, in the case of a July
Employee, on the first business day of July of such Payment Period) and (ii) 85%
of the fair market value of the Common Stock on the last business day of the
Payment Period, in either event rounded up to the nearest cent. The foregoing
limitation on the number of shares subject to option and the Option Price shall
be subject to adjustment as provided in Article 12.
 
     For purposes of the 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
 
                                       A-2

<PAGE>   27
 
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.
 
     For purposes of the Plan, the term "business day" means a day on which
there is trading on The Nasdaq Stock Market or the aforementioned national
securities exchange, whichever is applicable pursuant to the preceding
paragraph; and if neither is applicable, a day that is not a Saturday, Sunday or
legal holiday in Massachusetts.
 
     Notwithstanding any other provision herein, no employee shall be granted an
option which permits the employee's right to purchase stock under the Plan, and
under all other Section 423(b) employee stock purchase plans of the Company and
any parent or subsidiary corporations, to accrue at a rate which exceeds $25,000
of fair market value of such stock (determined on the date or dates that options
on such stock were 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. If the participant's
accumulated payroll deductions on the last day of the Payment Period would
otherwise enable the participant to purchase Common Stock in excess of the
Section 423(b)(8) $25,000 limitation described in this paragraph, the excess of
the amount of the accumulated payroll deductions over the aggregate purchase
price of the shares actually purchased shall be promptly refunded to the
participant by the Company, without interest.
 
ARTICLE 6 -- EXERCISE OF OPTION.
 
     Each eligible employee who continues to be a participant in the Plan on the
last day of a Payment Period shall be deemed to have exercised his or her 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 the
participant's accumulated payroll deductions on such date will pay for at the
Option Price, subject to the 3,000 share limit of the option and the Section
423(b)(8) $25,000 limitation described in Article 5. If the individual is not a
participant on the last day of a Payment Period, then he or she shall not be
entitled to exercise his or her option. Only full shares of Common Stock may be
purchased under the Plan. Unused payroll deductions remaining in a participant's
account at the end of a Payment Period solely by reason of the inability to
purchase a fractional share (and for no other reason) shall be refunded.
 
ARTICLE 7 -- AUTHORIZATION FOR ENTERING THE PLAN.
 
     An employee may elect to enter the Plan by filling out, signing and
delivering to the Company an authorization:
 
          A. Stating the percentage to be deducted from the employee's pay;
 
          B. Authorizing the purchase of stock for the employee in each Payment
     Period in accordance with the terms of the Plan; and
 
          C. Specifying the exact name or names in which stock purchased for the
     employee is to be issued as provided under Article 11 hereof.
 
     Such authorization must be received by the Company at least thirty days
before the first day of the next succeeding Payment Period or fifteen days prior
to the first day of July of such Payment Period in the case of a July Employee.
 
     Unless a participant files a new authorization or withdraws from the Plan,
the deductions and purchases under the authorization the participant has on file
under the Plan will continue from one Payment Period to succeeding Payment
Periods as long as the Plan remains in effect.
 
                                       A-3

<PAGE>   28
 
     The Company will accumulate and hold for each participant's account the
amounts deducted from his or her pay. No interest will be paid on these amounts.
 
ARTICLE 8 -- MAXIMUM AMOUNT OF PAYROLL DEDUCTIONS.
 
     An employee may authorize payroll deductions in an amount (expressed as a
whole percentage) not less than two percent (2%) but not more than ten percent
(10%) of the employee's cash compensation.
 
ARTICLE 9 -- CHANGE IN PAYROLL DEDUCTIONS.
 
     Deductions may not be increased during a Payment Period. Deductions may be
decreased during a Payment Period, provided that an employee may not decrease
his deduction more often than twice during any Payment Period (and with respect
to July Employees once during any Payment Period).
 
ARTICLE 10 -- WITHDRAWAL FROM THE PLAN.
 
     A participant may withdraw from the Plan (in whole but not in part) at any
time prior to the last day of a Payment Period by delivering a withdrawal notice
to the Company.
 
     To re-enter the Plan, an employee who has previously withdrawn must file a
new authorization at least thirty days before the first day of the next Payment
Period in which he or she wishes to participate. The employee's re-entry into
the Plan becomes effective at the beginning of such Payment Period, provided
that he or she is an eligible employee on the first business day of the Payment
Period.
 
ARTICLE 11 -- ISSUANCE OF STOCK.
 
     Certificates for stock issued to participants shall be delivered as soon as
practicable after each Payment Period by the Company's transfer agent.
 
     Stock purchased under the Plan shall be issued only in the name of the
participant, or if the participant's authorization so specifies, in the name of
the participant and another person of legal age as joint tenants with rights of
survivorship.
 
ARTICLE 12 -- ADJUSTMENTS.
 
     Upon the happening of any of the following described events, a
participant's rights under options granted under the Plan shall be adjusted as
hereinafter provided:
 
          A. In the event that the shares of Common Stock shall be subdivided or
     combined into a greater or smaller number of shares or if, upon a
     reorganization, split-up, liquidation, recapitalization or the like of the
     Company, the shares of Common Stock shall be exchanged for other securities
     of the Company, each participant 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 as were exchangeable for the
     number of shares of Common Stock that such participant 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 options hereunder, each participant upon
     exercising such an option shall be entitled to receive (for the purchase
     price paid upon such exercise) the shares as to which the participant is
     exercising his or her 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
 
                                       A-4

<PAGE>   29
 
     number of shares thereof and the amount of cash in lieu of fractional
     shares, respectively, which the participant would have received if the
     participant had been the holder of the shares as to which the participant
     is exercising his or her 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 been or may be granted under the Plan and the limitations set forth
in the second paragraph of Article 5 shall also be appropriately adjusted to
reflect the events specified in paragraphs A and B above. Notwithstanding the
foregoing, any adjustments made pursuant to paragraphs A or B shall be made only
after the Committee, based on advice of counsel for the Company, determines
whether such adjustments would constitute a "modification" (as that term is
defined in Section 424 of the Code). If the Committee determines that such
adjustments would constitute a modification, it may refrain from making such
adjustments.
 
     If the Company is to be consolidated with or acquired by another entity in
a merger, a 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, with respect to options then outstanding under the Plan, either (i) make
appropriate provision for the continuation of such options by arranging for the
substitution on an equitable basis for the shares then subject to such options
either (a) the consideration payable with respect to the outstanding shares of
the Common Stock in connection with the Acquisition, (b) shares of stock of the
successor corporation, or a parent or subsidiary of such corporation, or (c)
such other securities as the Successor Board deems appropriate, the fair market
value of which shall not exceed the fair market value of the shares of Common
Stock subject to such options immediately preceding the Acquisition; or (ii)
terminate each participant's options in exchange for a cash payment equal to the
excess of the fair market value on the date of the Acquisition of the number of
shares of Common Stock that the participant's accumulated payroll deductions as
of the date of the Acquisition could purchase, at an option price determined
with reference only to the first business day of the applicable Payment Period
(or the first business day of July of such Payment Period in the case of a July
Employee) and subject to the 3,000 share limit, Code Section 423(b)(8) and
fractional-share limitations on the amount of stock a participant would be
entitled to purchase over the aggregate option price to such participant
thereof.
 
     The Committee or Successor Board shall determine the adjustments to be made
under this Article 12, and its determination shall be conclusive.
 
ARTICLE 13 -- NO TRANSFER OR ASSIGNMENT OF EMPLOYEE'S RIGHTS.
 
     An option granted under the Plan may not be transferred or assigned,
otherwise than by will or by the laws of descent and distribution. Any option
granted under the Plan may be exercised, during the participant's lifetime, only
by the participant.
 
ARTICLE 14 -- TERMINATION OF EMPLOYEE'S RIGHTS.
 
     Whenever a participant ceases to be an eligible employee because of
retirement, voluntary or involuntary termination, resignation, layoff,
discharge, death or for any other reason, his or her rights under the Plan shall
immediately terminate, and the Company shall promptly refund, without interest,
the entire balance of his or her payroll deduction account under the Plan;
provided, however, that if an employee is laid off 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. Notwithstanding the foregoing,
eligible employment shall be treated as continuing intact while a participant is
on military leave, sick leave or other bona fide leave of absence, for up to 90
days, or, if such leave is longer than 90 days, for so long as the participant's
right to re-employment is
 
                                       A-5

<PAGE>   30
 
guaranteed either by statute or by written contract. 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 3
months prior to the last day of the Payment Period, such participant's rights
under the Plan are not immediately terminated, and if the participant has not
withdrawn from the 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.
 
ARTICLE 15 -- 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.
If at any time shares of stock reserved for the purpose 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 the amount of payroll deductions accumulated on
behalf of each participant that would otherwise be used to purchase stock, 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,
without interest.
 
     The Committee or the Board of Directors may from time to time adopt
amendments to the Plan provided that, without the approval of the shareholders
of the Company, no amendment may (i) increase the number of shares that may be
issued under the Plan; (ii) change the class of employees eligible to receive
options under the Plan, if such action would be treated as the adoption of a new
plan for purposes of Code Section 423(b) and the regulations thereunder; or
(iii) cause Rule 16b-3 under the Securities Exchange Act of 1934 to become
inapplicable to the Plan.
 
ARTICLE 16 -- LIMITS ON SALE OF STOCK PURCHASED UNDER THE PLAN.
 
     The Plan is intended to provide shares of 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 or her own affairs. An employee may,
therefore, sell stock purchased under the Plan at any time the employee chooses,
subject to compliance with any applicable federal or state securities laws and
subject to any restrictions imposed under Article 21 to ensure that tax
withholding obligations are satisfied. THE EMPLOYEE ASSUMES THE RISK OF ANY
MARKET FLUCTUATIONS IN THE PRICE OF THE STOCK.
 
ARTICLE 17 -- PARTICIPATING SUBSIDIARIES.
 
     The term "participating subsidiary" shall mean any present or future
subsidiary of the Company, as that term is defined in Section 424(f) of the
Code, that is designated from time to time by the Board of Directors to
participate in the Plan. The Board of Directors shall have the power to make
such designation before or after the Plan is approved by the shareholders.
 
ARTICLE 18 -- OPTIONEES NOT SHAREHOLDERS.
 
     Neither the granting of an option to an employee nor the deductions from
his or her pay shall constitute such employee a stockholder of the shares
covered by an option until such shares have been actually purchased by the
employee.
 
ARTICLE 19 -- 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.
 
                                       A-6

<PAGE>   31
 
ARTICLE 20 -- NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION.
 
     By electing to participate in the Plan, each participant agrees to notify
the Company in writing immediately after the participant transfers Common Stock
acquired under the Plan, if such transfer occurs within two years after the
first business day of the Payment Period in which such Common Stock was
acquired. Each participant further agrees to provide any information about such
a transfer as may be requested by the Company or any subsidiary corporation in
order to assist it in complying with the tax laws. Such dispositions generally
are treated as "disqualifying dispositions" under Sections 421 and 424 of the
Code, which have certain tax consequences to participants and to the Company and
its participating subsidiaries.
 
ARTICLE 21 -- WITHHOLDING OF ADDITIONAL INCOME TAXES.
 
     By electing to participate in the Plan, each participant acknowledges that
the Company and its participating subsidiaries are required to withhold taxes
with respect to the amounts deducted from the participant's compensation and
accumulated for the benefit of the participant under the Plan, and each
participant agrees that the Company and its participating subsidiaries may
deduct additional amounts from the participant's compensation, when amounts are
added to the participant's account, used to purchase Common Stock or refunded,
in order to satisfy such withholding obligations. Each participant further
acknowledges that when Common Stock is purchased under the Plan the Company and
its participating subsidiaries may be required to withhold taxes with respect to
all or a portion of the difference between the fair market value of the Common
Stock purchased and its purchase price, and each participant agrees that such
taxes may be withheld from compensation otherwise payable to such participant.
It is intended that tax withholding will be accomplished in such a manner that
the full amount of payroll deductions elected by the participant under Article 7
will be used to purchase Common Stock. However, if amounts sufficient to satisfy
applicable tax withholding obligations have not been withheld from compensation
otherwise payable to any participant, then, notwithstanding any other provision
of the Plan, the Company may withhold such taxes from the participant's
accumulated payroll deductions and apply the net amount to the purchase of
Common Stock, unless the participant pays to the Company, prior to the exercise
date, an amount sufficient to satisfy such withholding obligations. Each
participant further acknowledges that the Company and its participating
subsidiaries may be required to withhold taxes in connection with the
disposition of stock acquired under the Plan and agrees that the Company or any
participating subsidiary may take whatever action it considers appropriate to
satisfy such withholding requirements, including deducting from compensation
otherwise payable to such participant an amount sufficient to satisfy such
withholding requirements or conditioning any disposition of Common Stock by the
participant upon the payment to the Company or such subsidiary of an amount
sufficient to satisfy such withholding requirements.
 
ARTICLE 22 -- GOVERNMENTAL REGULATIONS.
 
     The Company's obligation to sell and deliver shares of Common Stock under
the Plan is subject to the approval of any governmental authority required in
connection with the authorization, issuance or sale of such shares.
 
     Government regulations may impose reporting or other obligations on the
Company with respect to the Plan. For example, the Company may be required to
identify shares of Common Stock issued under the Plan on its stock ownership
records and send tax information statements to employees and former employees
who transfer title to such shares.
 
ARTICLE 23 -- GOVERNING LAW.
 
     The validity and construction of the Plan shall be governed by the laws of
Massachusetts, without giving effect to the principles of conflicts of law
thereof.
 
                                       A-7

ARTICLE 24 - APPROVAL OF BOARD OF DIRECTORS AND STOCKHOLDERS OF THE COMPANY.
 
     The Plan was adopted by the Board of Directors on March 19, 1996 and on
such date the Board of Directors resolved that the Plan was to be submitted to
the shareholders of the Company for approval at the next meeting of
shareholders. If the Plan does not receive such approval, all payroll deductions
shall be returned without interest and the Plan shall be terminated.

                                 TERADYNE, INC.
                         1991 EMPLOYEE STOCK OPTION PLAN

        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
424 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 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 individuals 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; (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 of 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.


<PAGE>   34
                                      -2-

        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 required by the Company in any manner. The
aggregate number of shares which may be issued pursuant to the Plan is
15,000,000, 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.

        No employee of the Company or any Related Corporation may be    granted
Options to acquire, in the aggregate, more than 150,000 shares of Common Stock
per year under the Plan. 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 or shall be repurchased by
the Company, the shares subject to such Option shall be included in the
determination of the aggregate number of shares of Common Stock deemed to have
been granted to such employee 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 400,000 NSOs may be granted under
the Plan for less than "fair market value" (as hereinafter defined).

           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 

<PAGE>   35
                                      -3-


(on that date) by an established quotation service for 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 (iii) five years from 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
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

<PAGE>   36
                                      -4-


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 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 statute.

        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 are 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 from 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, 

<PAGE>   37
                                      -5-


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 into a greater or smaller number of shares or
        if the Company shall issue any shares of Common Stock as a stock
        dividend on its outstanding 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 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 Options 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 424 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 OR LIQUIDATION.  In the event of the proposed 
        dissolution 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.

<PAGE>   38

                                      -6-


               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.

               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 shall determine the
        specific adjustments to be made under 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 to the cash exercise price of the Option, or (c) at the
discretion of the Committee in exceptional cases, by delivery of the optionee's
personal 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), (c) or (d) 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, provided that the Committee
shall allow for such payment at the time of grant of the ISO. The holder of an
Option shall not have the rights of a shareholder with respect to the shares
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 

<PAGE>   39
                                      -7-


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 this 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.

        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 taxes 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 ISO 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
expiration 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.
