                                  GENRAD, INC.

                  1997 NON-QUALIFIED EMPLOYEE STOCK OPTION PLAN
                        as amended through August 4, 2000

1.  PURPOSE

         The purpose of this 1997 Non-Qualified Employee Stock Option Plan (the
"Plan") is to advance the interests of GenRad, Inc. (the "Company") by enhancing
the ability of the Company and its subsidiaries to attract and retain employees,
consultants or advisers who are in a position to make significant contributions
to the success of the Company, to reward them for their contributions and to
encourage them to take into account the long-term interests of the Company.

         The Plan provides for the award of options to purchase shares of the
Company's common stock ("Stock"). Options granted pursuant to the Plan shall be
non-qualified options and not incentive stock options as defined in Section 422
of the Internal Revenue Code of 1986.

2.  ELIGIBILITY FOR AWARDS

         Persons eligible to receive awards under the Plan shall be all
employees, consultants and advisers of the Company and its subsidiaries who, in
the opinion of the Board, are in a position to make a significant contribution
to the success of the Company and its subsidiaries. Directors and officers of
the Company shall not be eligible to receive awards under the Plan. A subsidiary
for purposes of the Plan shall be a corporation in which the Company owns,
directly or indirectly, stock possessing 50% or more of the total combined
voting power of all classes of stock. Persons selected for awards under the Plan
are referred to herein as "participants".

3.  ADMINISTRATION

         The Plan shall be administered by the Board of Directors (the "Board")
of the Company. The Board shall have authority, not inconsistent with the
express provisions of the Plan, (a) to grant awards consisting of options to
such participants as the Board may select; (b) to determine the time or times
when awards shall be granted and the number of shares of Stock subject to each
award; (c) to determine the terms and conditions of each award; (d) to prescribe
the form or forms of any instruments evidencing awards and any other instruments
required under the Plan and to change such forms from time to time; (e) to
adopt, amend and rescind rules and regulations for the administration of the
Plan; and (f) to interpret the Plan and to decide any questions and settle all
controversies and disputes that may arise in connection with the Plan. Such
determination of the Board shall be conclusive and shall bind all parties.
Subject to Section 8, the Board shall also have the authority, both generally
and in particular instances, to waive compliance by a participant with any
obligation to be performed by the participant under an award, to waive any
condition or provision of an award, and to amend or cancel any award (and if an
award is canceled, to grant a new award on such terms as the Board shall
specify), except that the Board may not take any action with respect to an
outstanding award that would adversely affect the rights of the participant
under such award without such participant's consent. Nothing in the preceding
sentence shall be construed as limiting the power of the Board to make
adjustments required by Section 5(c) and Section 6(i).

<PAGE>

         The Board may, in its discretion, delegate some or all of its powers
with respect to the Plan to a committee (the "Committee"), in which event all
references in this Plan (as appropriate) to the Board shall be deemed to refer
to the Committee. The Committee, if one is appointed, shall consist of at least
two directors. A majority of the members of the Committee shall constitute a
quorum, and all determinations of the Committee shall be made by a majority of
its members. Any determination of the Committee under the Plan may be made
without notice or meeting of the Committee by a writing signed by a majority of
the Committee members.

4.  EFFECTIVE DATE AND TERM OF PLAN

         The Plan shall become effective on the date on which it is approved by
the Board.

         No awards shall be granted under the Plan after the completion of ten
years from the date on which the Plan was adopted by the Board, but awards
previously granted may extend beyond that date.

5.  SHARES SUBJECT TO THE PLAN

         (a) Number of Shares. Subject to adjustment as provided in Section
5(c), the aggregate number of shares of Stock that may be delivered upon the
exercise of awards granted under the Plan shall be 4,500,000. If any award
granted under the Plan terminates without having been exercised in full, or upon
exercise is satisfied other than by delivery of Stock, the number of shares of
Stock as to which such award was not exercised shall be available for future
grants within the limits set forth in this Section 5(a).

         (b) Shares to be Delivered. Shares delivered under the Plan shall be
authorized but unissued Stock or, if the Board so decides in its sole
discretion, previously issued Stock acquired by the Company and held in its
treasury. No fractional shares of Stock shall be delivered under the Plan.

         (c) Changes in Stock. In the event of a stock dividend, stock split or
combination of shares, recapitalization or other change in the Company's capital
stock, the number and kind of shares of Stock subject to awards then outstanding
or subsequently granted under the Plan, the exercise price of such awards, the
maximum number of shares of Stock that may be delivered under the Plan, and
other relevant provisions shall be appropriately adjusted by the Board, whose
determination shall be binding on all persons.

         The Board may also adjust the number of shares subject to outstanding
awards and the exercise price and the terms of outstanding awards to take into
consideration material changes in accounting practices or principles,
extraordinary dividends, consolidations or mergers (except those described in
Section 6(i)), acquisitions or dispositions of stock or property or any other
event if it is determined by the Board that such adjustment is appropriate to
avoid distortion in the operation of the Plan.

6.  TERMS AND CONDITIONS OF OPTIONS

         (a) Exercise Price of Options. The exercise price of each option shall
be determined by the Board but shall not be less, in the case of an original
issue of authorized stock, than par value.

         (b) Duration of Options. Options shall be exercisable during such
period or periods as the Board may specify. The latest date on which an option
may be exercised (the "Final Exercise Date") shall be the date that is ten years
from the date the option was granted or such earlier date as the Board may
specify at the time the option is granted.

                                       2

         (c)  Exercise of Options.

                (i)   Options shall become exercisable at such time or times and
                      upon such conditions as the Board shall specify. In the
                      case of an option not immediately exercisable in full, the
                      Board may at any time accelerate the time at which all or
                      any part of the option may be exercised.

                (ii)  Options may be exercised only in writing. Written notice
                      of exercise must be signed by the proper person and
                      furnished to the Company, together with (A) such documents
                      as the Board requires and (B) payment in full as specified
                      below in Section 6(d) for the number of shares for which
                      the option is exercised.

                (iii) The delivery of Stock upon the exercise of an option shall
                      be subject to compliance with (A) applicable federal and
                      state laws and regulations, (B) if the outstanding Stock
                      is at the time listed on any stock exchange, the listing
                      requirements of such exchange, and (C) Company counsel's
                      approval of all other legal matters in connection with the
                      issuance and delivery of such Stock. If the sale of Stock
                      has not been registered under the Securities Act of 1933,
                      as amended, the Company may require, as a condition to
                      exercise of the option, such representations or agreements
                      as counsel for the Company may consider appropriate to
                      avoid violation of such Act and may require that the
                      certificates evidencing such Stock bear an appropriate
                      legend restricting transfer.

                (iv)  The Board shall have the right to require that the
                      participant exercising the option remit to the Company an
                      amount sufficient to satisfy any federal, state, or local
                      withholding tax requirements (or make other arrangements
                      satisfactory to the Company with regard to such taxes)
                      prior to the delivery of any Stock pursuant to the
                      exercise of the option. If permitted by the Board, either
                      at the time of the grant of the option or the time of
                      exercise, the participant may elect, at such time and in
                      such manner as the Board may prescribe, to satisfy such
                      withholding obligation by (A) delivering to the Company
                      Stock (which in the case of Stock acquired from the
                      Company shall have been owned by the participant for at
                      least six months prior to the delivery date) having a fair
                      market value equal to such withholding obligation, or (B)
                      requesting that the Company withhold from the shares of
                      Stock to be delivered upon the exercise a number of shares
                      of Stock having a fair market value equal to such
                      withholding obligation.

                (v)   If an option is exercised by the executor or administrator
                      of a deceased participant, or by the person or persons to
                      whom the option has been transferred by the participant's
                      will or the applicable laws of descent and distribution,
                      the Company shall be under no obligation to deliver Stock
                      pursuant to such exercise until the Company is satisfied
                      as to the authority of the person or persons exercising
                      the option.

         (d) Payment for and Delivery of Stock. Stock purchased upon exercise
of an option under the Plan shall be paid for as follows:

                (i)   in cash or by personal check, certified check, bank draft
                      or money order payable to the order of the Company; or

                                       3
<PAGE>

                (ii)  if so permitted by the Board, (A) through the delivery of
                      shares of Stock (which, in the case of Stock acquired from
                      the Company, shall have been held for at least six months
                      prior to delivery) having a fair market value on the last
                      business day preceding the date of exercise equal to the
                      purchase price or (B) by delivery of a promissory note of
                      the participant to the Company, such note to be payable on
                      such terms as are specified by the Board or (C) by
                      delivery of an unconditional and irrevocable undertaking
                      by a broker to deliver promptly to the Company sufficient
                      funds to pay the exercise price or (D) by any combination
                      of the permissible forms of payment; provided, that if the
                      Stock delivered upon exercise of the option is an original
                      issue of authorized Stock, at least so much of the
                      exercise price as represents the par value of such Stock
                      shall be paid by a personal check or promissory note of
                      the person exercising the option.

         (e) Rights as Shareholder. A participant shall not have the rights of a
shareholder with regard to awards under the Plan except as to Stock actually
received by the participant under the Plan.

         (f) Nontransferability of Awards; Restrictions on Stock. Except as the
Board may otherwise determine, no award may be transferred other than by will or
by the laws of descent and distribution, and during a participant's lifetime an
award may be exercised only by the participant.

         The Board, in its discretion, may at the time an award is granted make
Stock delivered under the award subject to such restrictions and conditions,
including restrictions on resale and buy-back rights, as it deems appropriate.

         (g) Death. Except as otherwise provided in the award by the Board at
the time of grant, if a participant dies, each option held by the participant
immediately prior to death may be exercised, to the extent it was exercisable
immediately prior to death, by the participant's executor or administrator or by
the person or persons to whom the option is transferred by will or the
applicable laws of descent and distribution, at any time within the one-year
period (or such longer or shorter period as the Board may determine) beginning
with the date of the participant's death but in no event beyond the Final
Exercise Date.

         (h) Termination of Service other than by Death. Except as otherwise
provided in the award by the Board at the time of grant, if an employee's
employment with the Company and its subsidiaries terminates for any reason other
than by death, all options held by the employee that are not then exercisable
shall terminate. Options that are exercisable on the date employment terminates
shall continue to be exercisable for a period of 30 days (or such longer period
as the Board may determine, but in no event beyond the Final Exercise Date)
unless the employee (i) was discharged for cause or (ii) resigned and within 30
days thereafter the Board determines that the participant's conduct prior to his
or her resignation warranted a discharge for cause. After completion of the
post-termination exercise period, such options shall terminate to the extent not
previously exercised, expired or terminated. For purposes of this Section 6(h),
(i) employment shall not be considered terminated (A) in the case of sick leave
or other bona fide leave of absence approved for purposes of the Plan by the
Board, so long as the employee's right to reemployment is guaranteed either by
statute or by contract, or (B) in the case of a transfer of employment between
the Company and a subsidiary or between subsidiaries and (ii) "cause" shall mean
willful misconduct by the participant or willful failure to perform his or her
responsibilities in the best interests of the Company (including, without
limitation, breach by the participant of any provision of any employment,
advisory, consulting, nondisclosure, non-competition or other agreement between
the participant and the Company or any subsidiary of the Company).

                                       4

<PAGE>

         In the case of a participant who is not an employee, provisions
relating to the exercisability of options following termination of service shall
be specified in the award. If not so specified, all options held by such
participant that are not then exercisable shall terminate upon termination of
service. Options that are exercisable on the date the participant's service as a
consultant or adviser terminates shall continue to be exercisable for a period
of 30 days (or such longer period as the Board may determine, but in no event
beyond the Final Exercise Date) unless the consultant or adviser (i) was
terminated for cause or (ii) resigned and within 30 days thereafter the Board
determines that the participant's conduct prior to his or her resignation
warranted a discharge for cause. After completion of the post-termination
exercise period, such options shall terminate to the extent not previously
exercised, expired or terminated.

         (i) Merger, Consolidation, Asset Sale, Liquidation, etc. In the event
of a consolidation or merger or sale of all or substantially all of the assets
of the Company in which outstanding shares of Stock are exchanged for
securities, cash or other property of any other corporation or business entity
or in the event of a liquidation of the Company, the Board, or the board of
directors of any corporation assuming the obligations of the Company, may, in
its discretion, take any one or more of the following actions, as to outstanding
options: (i) provide that such options shall be assumed, or equivalent options
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof), (ii) upon written notice to the optionees, provide that all
unexercised options will terminate immediately prior to the consummation of such
transaction unless exercised by the optionee within a specified period following
the date of such notice, (iii) in the event of a merger under the terms of which
holders of the Stock will receive upon consummation thereof a cash payment for
each share surrendered in the merger (the "Merger Price"), make or provide for a
cash payment to the optionees equal to the difference between (A) the Merger
Price times the number of shares of Stock subject to such outstanding options
(to the extent then exercisable at prices not in excess of the Merger Price) and
(B) the aggregate exercise price of all such outstanding options in exchange for
the termination of such options, and (iv) provide that all or any outstanding
options shall become exercisable in full and all restrictions on outstanding
awards shall terminate immediately prior to such event.

         The Company may grant options under the Plan in substitution for
options held by employees of another corporation who become employees of the
Company, or a subsidiary of the Company, as the result of a merger or
consolidation of the employing corporation with the Company or a subsidiary of
the Company, or as a result of the acquisition by the Company, or one of its
subsidiaries, of property or stock of the employing corporation. The Company may
direct that substitute options be granted on such terms and conditions as the
Board considers appropriate in the circumstances.

         (j) Change in Control. Notwithstanding any other provision of the Plan
and except as otherwise provided in the relevant option agreement, in the event
of a "Change in Control of the Company" (as defined below), the exercise dates
of all options then outstanding shall be accelerated in full, and any
restrictions on exercising outstanding options issued pursuant to the Plan prior
to any given date shall terminate. For purposes of the Plan, a "Change in
Control of the Company" shall occur or be deemed to have occurred only if (i)
any "person", as such term is used in Sections 13(d) and 14(d) of the Securities
Exchange Act of 1934, as amended ("Exchange Act"), (other than the Company, any
trustee or other fiduciary holding securities under an employee benefit plan of
the Company, or any corporation owned directly or indirectly by the shareholder
of the Company in substantially the same proportion as their ownership of stock
of the Company), is or becomes the "beneficial owner" (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Company
representing 50% or more of the combined voting power of the Company's then
outstanding securities; (ii) during any period of two consecutive years ending
during the term of the Plan (not including any period prior to the adoption of
the Plan), individuals who at the beginning of such period constitute the Board,
and any new director

                                       5
<PAGE>

(other than a director designated by a person who has entered into an agreement
with the Company to effect any transaction described in clause (i), (iii) or
(iv) of this subsection (j)) whose election by the Board or nomination for
election by the Company's shareholders was approved by a vote of at least
two-thirds of the directors then still in office who were either directors at
the beginning of the period or whose election or whose nomination for election
was previously so approved (collectively, the "Disinterested Directors"), cease
for any reason to constitute a majority of the Board; (iii) the shareholders of
the Company approve a merger or consolidation of the Company with any other
corporation, other than (A) a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) more than 50% of the combined
voting power of the voting securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation or (B) a merger or
consolidation effected to implement a recapitalization of the Company (or
similar transaction) in which no "person" (as hereinabove defined) acquires more
than 50% of the combined voting power of the Company's then outstanding
securities; or (iv) the shareholders of the Company approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all of the Company's assets which, in either
case, has not previously been approved by a majority of the Disinterested
Directors.

7.  EMPLOYMENT RIGHTS

         Neither the adoption of the Plan nor the grant of awards shall confer
upon any participant any right to continue as an employee of, or consultant or
adviser to, the Company or any subsidiary of the Company or affect in any way
the right of the Company or any such subsidiary to terminate his or her
employment by the Company or any subsidiary of the Company at any time. Except
as specifically provided by the Board in any particular case, the loss of
existing or potential profit in awards granted under this Plan shall not
constitute an element of damages in the event of termination of the relationship
of a participant even if the termination is in violation of an obligation of the
Company or any subsidiary of the Company to the participant by contract or
otherwise.

8.   EFFECT, DISCONTINUANCE, CANCELLATION, AMENDMENT AND TERMINATION

         Neither adoption of the Plan nor the grant of awards to a participant
shall affect the Company's right to make awards to such participant that are not
subject to the Plan, to issue to such participant Stock as a bonus or otherwise,
or to adopt other plans or arrangements under which Stock may be issued.

         The Board may at any time discontinue granting awards under the Plan.
With the consent of the participant (except as otherwise provided in the Plan),
the Board may at any time cancel an existing award in whole or in part and grant
another award for such number of shares as the Board specifies. The Board may at
any time or times amend the Plan or any outstanding award for the purpose of
satisfying changes in applicable laws or regulations or for any other purpose
that may at the time be permitted by law, or may at any time terminate the Plan
as to further grants of awards, but no such amendment shall adversely affect the
rights of any participant (without the participant's consent) under any award
previously granted.

                                  GENRAD, INC.

                      NON-STATUTORY STOCK OPTION AGREEMENT

1.       GRANT OF OPTION:

         GenRad, Inc., a Massachusetts corporation (the "Company"), hereby
grants Robert M. Dutkowsky (the " Optionee") an option to purchase up to an
aggregate of 500,000 shares of Common Stock of the Company ("Common Stock") at a
price of $7.375 per share (the "Option Exercise Price"), purchasable as set
forth in, and subject to the terms and conditions of, this option. Except where
the context otherwise requires, the term "Company" shall include the parent and
all present and future subsidiaries of the Company as defined in Section 424(e)
and 424(f) of the Internal Revenue Code of 1986, as amended or replaced from
time to time (the "Code").
         The date of grant of this option is April 24, 2000 (the "Effective
Date").

2.       NON-STATUTORY STOCK OPTION:

         This option is not intended to qualify as an incentive stock option
within the meaning of Section 422 of the Code.

3.       EXERCISE OF OPTION AND PROVISIONS FOR TERMINATION:

         (a)      TIMING OF EXERCISE.

                  Except as otherwise provided in this Agreement, this option
                  may be exercised at any time, in whole or in part, subject to
                  the Company's right to repurchase of this Agreement any shares
                  acquired upon exercise of this option in accordance with
                  Section 12 of this Agreement.

         (b)      EXERCISE PROCEDURE.

                  Subject to the conditions set forth in this Agreement, this
                  option shall be exercised by the Optionee's delivery of
                  written notice of exercise to the Treasurer of the Company,
                  specifying the number of shares to be purchased and the
                  purchase price to be paid therefor and accompanied by payment
                  in full in accordance with Section 4. Such exercise shall be
                  effective upon receipt by the Treasurer of the Company of such
                  written notice together with the required payment. The
                  Optionee may at any time or from time to time purchase less
                  than the number of shares covered hereby, provided that no
                  partial exercise of this option may be for any fractional
                  share or for fewer than ten whole shares.

         (c)      TERMINATION OF EMPLOYMENT.

                  If the Optionee ceases to be employed by the Company for any
                  reason other than death, this option shall continue to be
                  exercisable during the thirty (30) days immediately following
                  such cessation, after which time the Option shall terminate.
                  If the Optionee ceases to be employed by the Company by reason
                  of his death, this option shall continue to be exercisable
                  either by the Optionee's executor or administrator or, if not
                  so exercised, by the legatees or distributees of the
                  Optionee's estate, during the twelve (12) months immediately
                  following the Optionee's death, after which time the Option
                  shall

                  terminate. The date on which the Optionee ceases to be
                  employed by the Company is hereinafter referred to as the
                  "Termination Date".

         (d)      EXPIRATION.

                  Notwithstanding any other provisions set forth in this
                  Agreement, in no event shall this option be exercised more
                  than ten (10) years after the Effective Date.

         (d)      TERMINATION FOR CAUSE.

                  Notwithstanding any other provisions set forth in this
                  Agreement, this option shall terminate automatically and
                  without notice to the Optionee on the date the Optionee's
                  employment is terminated for "cause" (as defined in the
                  Employment Agreement dated April 10, 2000 between the Company
                  and the Optionee). A termination for "cause" will include any
                  resignation in anticipation of discharge for "cause" or
                  accepted by the Company in lieu of a formal discharge for
                  "cause".

4.       PAYMENT OF PURCHASE PRICE.

         (a)      METHOD OF PAYMENT.

                  Payment of the purchase price for shares purchased upon
                  exercise of this option shall be made (i) by delivery to the
                  Company of cash or a check to the order of the Company in an
                  amount equal to the purchase price of such shares, (ii) with
                  the approval of the Compensation Committee of the Company's
                  Board of Directors (the "Compensation Committee"), by delivery
                  to the Company of shares of Common Stock of the Company then
                  owned by the Optionee having a fair market value equal in
                  amount to the purchase price of such shares, (iii) by any
                  other means which the Compensation Committee determines are
                  consistent with applicable laws and regulations (including,
                  without limitation, the provisions of Rule 16b-3 under the
                  Securities Exchange Act of 1934 and Regulation T promulgated
                  by the Federal Reserve Board), or (iv) by any combination of
                  such methods of payment.

         (b)      VALUATION OF SHARES OR OTHER NON-CASH CONSIDERATION TENDERED
                  IN PAYMENT OF PURCHASE PRICE.

                  For the purposes hereof, the fair market value of any share of
                  the Company's Common Stock or other non-cash consideration
                  which may be delivered to the Company in exercise of this
                  option shall be determined in good faith by the Compensation
                  Committee.

         (c)      DELIVERY OF SHARES TENDERED IN PAYMENT OF PURCHASE PRICE.

                  If the Optionee exercises this option by delivery of shares of
                  Common Stock of the Company, the certificate or certificates
                  representing the shares of Common Stock of the Company to be
                  delivered shall be duly executed in blank by the Optionee or
                  shall be accompanied by a stock power duly executed in blank
                  suitable for purposes of transferring such shares to the
                  Company. Fractional shares of Common Stock of the Company will
                  not be accepted in payment of the purchase price of shares
                  acquired upon exercise of this option.

         (d)      RESTRICTIONS ON USE OF OPTION STOCK TO PAY PURCHASE PRICE.

                  Notwithstanding the foregoing, no shares of Common Stock of
                  the Company may be tendered in payment of the purchase price
                  of shares purchased upon exercise of this option if the shares
                  to be so tendered were acquired within twelve (12) months
                  before the date of such tender through the exercise of an
                  option granted under any stock option plan of the Company or
                  through any restricted stock plan of the Company.

5.       DELIVERY OF SHARES; COMPLIANCE WITH SECURITIES LAWS, ETC.

         (a)      GENERAL.

                  The Company shall, upon payment of the option price for the
                  number of shares purchased and paid for, make prompt delivery
                  of the certificate representing such shares to the Optionee,
                  provided that if any law or regulation requires the Company to
                  take any action with respect to such shares before the
                  issuance thereof, then the date of delivery of such
                  certificate shall be extended for the period necessary to
                  complete such action.

         (b)      LISTING, QUALIFICATIONS, ETC.

                  This option shall be subject to the requirement that if, at
                  any time, counsel to the Company shall determine that the
                  listing, registration or qualification of the shares subject
                  hereto upon any securities exchange or under any state or
                  federal law, or the consent or approval of any governmental or
                  regulatory body, or that the disclosure of non-public
                  information or the satisfaction of any other condition is
                  necessary as a condition of, or in connection with, the
                  issuance or purchase of shares hereunder, this option may not
                  be exercised, in whole or in part, unless such listing,
                  registration, qualification, consent or approval, disclosure
                  or satisfaction of such other condition shall have been
                  effected or obtained on terms acceptable to the Compensation
                  Committee.

6.       NON-TRANSFERABILITY OF OPTION.

         This option is personal and no rights granted hereunder may be
transferred, assigned, pledged or hypothecated in any way (whether by operation
of law or otherwise) nor shall any such rights be subject to execution,
attachment or similar process, except that this option may be transferred by
will or the laws of descent and distribution or with the prior approval of the
Compensation Committee. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of this option or of such rights contrary to
the provisions hereof, or upon the levy of any attachment or similar process
upon this option or such rights, this option and such rights shall, at the
election of the Company, become, null and void.

7.       NO SPECIAL EMPLOYMENT OR SIMILAR RIGHTS.

         Nothing contained in this Agreement shall be construed or deemed by any
person under any circumstances to bind the Company to continue the employment of
the Optionee with the Company.

8.       RIGHTS AS A SHAREHOLDER.

         The Optionee shall have no rights as a shareholder with respect to any
shares which may be purchased by exercise of this option (including, without
limitation, any rights to receive dividends or non-cash distributions with
respect to such shares), unless and until a certificate representing such shares

                                       3
<PAGE>

is duly issued and delivered to the Optionee. No adjustment shall be made for
dividend or other rights for which the record date is prior to the date such
stock certificate is issued.

9.       ADJUSTMENT PROVISIONS.

         (a)      GENERAL.

                  If, through or as a result of any recapitalization,
                  reclassification, stock dividend, stock split, reverse stock
                  split or other similar transaction involving shares of Common
                  Stock (i) the outstanding shares of Common Stock are increased
                  or decreased or are exchanged for a different number of kind
                  of shares or other securities of the Company, or (ii)
                  additional shares or new or different shares of other
                  securities of the Company or other non-cash assets are
                  distributed with respect to such shares of Common Stock or
                  other securities, an appropriate and proportionate adjustment
                  may be made in (x) the number and kind of shares or other
                  securities then subject to this option, and (y) the price for
                  each share then subject to this option, without changing the
                  aggregate purchase price as to which this option remains
                  exercisable.

         (b)      COMPENSATION COMMITTEE AUTHORITY TO MAKE ADJUSTMENTS.

                  Any adjustments under this Section 9 will be made by the
                  Compensation Committee, whose determination as to what
                  adjustments, if any, will be made and the extent thereof will
                  be final, binding and conclusive. No fractional shares will be
                  issued pursuant to this option on account of any such
                  adjustments.

10.      MERGERS, CONSOLIDATIONS, DISTRIBUTIONS, LIQUIDATIONS, ETC.

         In the event of a consolidation or merger or sale of all or
substantially all of the assets of the Company in which outstanding shares of
Common Stock are exchanged for securities, cash or other property of any other
corporation or business entity or in the event of a liquidation of the Company,
prior to the termination of this option, the Board of Directors of the Company
or the board of directors of any corporation assuming the obligations of the
Company, may, in its discretion, take any one or more of the following actions,
as to this option: (i) provide that this option shall be assumed, or an
equivalent option shall be substituted, by the acquiring or succeeding
corporation (or an affiliate thereof), (ii) upon written notice to the Optionee,
provide that any unexercised portion of this option will terminate immediately
prior to the consummation of such transaction unless exercised by the Optionee
within a specified period following the date of such notice, and (iii) in the
event of a merger under the terms of which holders of the Common Stock of the
Company will receive upon consummation thereof a cash payment for each share
surrendered in the merger (the "Merger Price"), make or provide for a cash
payment to the Optionee equal to the difference between (A) the Merger Price
times the number of shares of Common Stock subject to the unexercised portion of
this option (to the extent then exercisable at prices not in excess of the
Merger Price) and (B) the aggregate exercise price of any unexercised portion of
this option, which cash payment shall be in exchange for the termination of this

         (a)      REPURCHASE RIGHT.

                  Subject to the terms of this Article 12, the Company shall
                  have the right and option, but not the obligation, to purchase
                  from the Optionee all or any part of the shares acquired by
                  the Optionee upon exercise of this option if a Termination
                  Date has occurred (the "Repurchase Right").

         (b)      REPURCHASE PRICE.

                  The Repurchase Right shall be exercised at the Option Exercise
                  Price, as equitably adjusted in the event of any stock split,
                  stock dividend or similar transaction.

         (c)      DURATION OF REPURCHASE RIGHT.

                  The Repurchase Right shall lapse (i) as to 125,000 shares of
                  Common Stock, adjusted in the event of any stock split, stock
                  dividend or similar transaction, on the first anniversary of
                  the Effective Date, (ii) as to an additional 125,000 shares of
                  Common Stock, adjusted in the event of any stock split, stock
                  dividend or similar transaction, on the second anniversary of
                  the Effective Date, (iii) as to an additional 125,000 shares
                  of Common Stock, adjusted in the event of any stock split,
                  stock dividend or similar transaction, on the third
                  anniversary of the Effective Date, and (iv) as to the final
                  125,000 shares of Common Stock, adjusted in the event of any
                  stock split, stock dividend or similar transaction, on the
                  fourth anniversary of the Effective Date. The Repurchase Right
                  shall lapse (i) as to 125,000 shares of Common Stock, adjusted
                  in the event of any stock split, stock dividend or similar
                  transaction, if the Optionee's employment with the Company is
                  terminated by the Company other than for cause (as defined in
                  the Employment Agreement) or by the Optionee for good reason
                  (as defined in the Employment Agreement) and (ii) in its
                  entirety (A) six months after the Termination Date has
                  occurred or (B) immediately upon a Change of Control (as
                  defined in the Employment Agreement).

         (d)      EXERCISE OF REPURCHASE RIGHT.

                  In the event the Company shall be entitled to and shall elect
                  to exercise the Repurchase Right, it shall give to the
                  Optionee (or his heirs or personal representative, as the case
                  may be) a written notice specifying such exercise, the number
                  of shares that the Company elects to repurchase and specifying
                  a date for closing hereunder, which date shall be not more
                  than ten (10) business days after the giving of such notice.

                  The closing shall take place at the Company's principal
                  offices or such other location as the Company may reasonably
                  designate in such notice. At the closing, the Optionee (or his
                  heirs or personal representative, as the case may be) shall
                  deliver the certificates representing the shares being
                  repurchased, duly endorsed in blank for transfer (and if the
                  seller shall be the heirs or personal representative of the
                  Optionee, together with proof as to the authority of the
                  person or persons to make such delivery), against the
                  simultaneous delivery to the Optionee (or his heirs or
                  personal representative, as the case may be) of the purchase
                  price for the number of shares then being repurchased. In the
                  event that the Optionee (or his heirs or personal
                  representative, as the case may be) fails so to deliver

                                       5
<PAGE>

                  the certificates for the shares to be repurchased duly
                  endorsed as aforesaid, the Company may elect (a) to establish
                  a segregated account in the amount of the purchase price, such
                  account to be turned over to the Optionee (or his heirs or
                  personal representative, as the case may be) upon delivery of
                  such certificates duly endorsed as aforesaid, and (b)
                  immediately to take such action as is appropriate to transfer
                  record title of such shares from the Optionee (or his heirs or
                  personal representative, as the case may be) to the Company
                  and to treat the Optionee (or his heirs or personal
                  representative, as the case may be) and such shares in all
                  respects as if delivery of the certificates for such shares
                  duly endorsed as aforesaid had been made as required. The
                  Optionee (and any heir or personal representative of the
                  Optionee, by reason of his or her receipt of the shares)
                  hereby irrevocably grants the Company a power of attorney for
                  the purpose of effectuating the preceding sentence.

         (e)      RIGHTS TO SHARES AND RESTRICTION ON TRANSFER DURING REPURCHASE
                  OPTION.

                  So long as shares acquired by the Optionee upon exercise of
                  this option have not been repurchased, the Optionee shall have
                  ownership rights with respect to the shares, including the
                  right to vote and to receive dividends. The Optionee may not
                  sell, transfer, pledge or hypothecate any shares that are
                  subject to the Repurchase Right except to a person or entity
                  which expressly agrees in writing with the Company to be bound
                  by the Repurchase Right.

         (f)      LEGENDS.

                  The Company may require that certificates representing any
                  shares to be issued to the Optionee upon exercise of this
                  Option which are subject to the Repurchase Right shall have
                  endorsed thereon a legend substantially as follows:

                           "The shares represented by this certificate are
                           subject to the repurchase rights and restrictions on
                           transfer set forth in a Non-Statutory Stock Option
                           Agreement dated April 24, 2000, a copy of which will
                           be furnished free of charge upon written request."

13.      MISCELLANEOUS.

         (a)      Except as provided herein, this option may not he amended or
                  otherwise modified unless evidenced in writing and signed by
                  the Company and the Optionee.

         (b)      All notices under this option shall be mailed or delivered by
                  hand to the. parties at their respective addresses set forth
                  beneath their names below or it such other address as may be
                  designated in writing by either of the parties to one another.

         (c)      Although this option has not been granted under the Company's
                  1991 Equity Incentive Plan (the "Plan"), it shall be governed
                  by the terms and conditions thereof except to the extent the
                  terms of this option and the terms of the Plan are
                  inconsistent or contradictory, in which event the terms of
                  this option shall govern.

         (d)      This option shall be governed by and construed in accordance
                  with the laws of the Commonwealth of Massachusetts.
