Options  granted  under the Plan.  Shares to be  delivered  upon the exercise of
Options  may be either  shares of Stock  which are  authorized  but  unissued or
shares of Stock held by the  Company in its  treasury.  If an Option  expires or
terminates for any reason without having been exercised in full, the unpurchased
shares  subject to the Option shall become  available for other Options  granted
under the Plan.  The  Company  shall,  at all times  during  which  Options  are
outstanding,  reserve and keep available  shares of Stock  sufficient to satisfy
such  Options,  and shall pay all fees and  expenses  incurred by the Company in
connection  therewith.  In the event of any  capital  change in the  outstanding
Stock as  contemplated  by Section  9.6,  the number and kind of shares of Stock
reserved and kept available by the Company shall be appropriately adjusted.

     7. Eligibility.  Each employee of a Participating Employer shall be granted
an Option on each Offering Commencement Date on which such employee meets all of
the following requirements:

          (a) The employee is customarily  employed by a Participating  Employer
     for more than  twenty  hours per week and has been  employed by one or more
     Participating Employers for at least twelve consecutive months prior to the
     applicable Offering Commencement Date.

          (b) The  employee  will  not,  after  grant of the  Option,  own stock
     possessing five or more percent of the total combined voting power or value
     of all classes of stock of the Company or of any Related  Corporation.  For
     purposes of this  paragraph  (b),  the rules of Section  424(d) of the Code
     shall apply in determining the stock  ownership of the employee,  and stock
     which the employee may purchase under outstanding  options shall be treated
     as stock owned by the employee.

          (c) Upon grant of the Option,  the employee's rights to purchase stock
     under all employee  stock  purchase  plans (as defined in Section 423(b) of
     the Code) of the Company and its Related  Corporations will not accrue at a
     rate which exceeds $25,000 of fair market value of the stock (determined as
     of 


                                      -4-
   5

     the grant date) for each calendar year in which such option is  outstanding
     at any time. The accrual of rights to purchase stock shall be determined in
     accordance with Section 423(b)(8) of the Code.

     8.  Offering  Commencement  Dates.  Options  shall be  granted on the first
business day of any calendar  month which is  designated by the Committee as the
beginning of an Offering Period.

     9. Terms and Conditions of Options.

     9.1.  General.  All Options granted on a particular  Offering  Commencement
Date  shall  comply  with the terms and  conditions  set forth in  Sections  9.2
through  9.10.  Subject  to  Sections  7(c) and 9.8,  each  Option  granted on a
particular  Offering  Commencement  Date shall  entitle the Optionee to purchase
that number of shares  equal to the lesser of (a) the result of five  percent of
the  Optionee's  Compensation  divided by 85 percent of the Market  Value of one
share of Stock on the  Offering  Commencement  Date and then  rounded  down,  if
necessary,  to the nearest whole number and (b) any number of shares established
by the  Committee as an additional  limitation  on the maximum  number of Option
Shares available under every Option granted on that Offering Commencement Date.

     9.2.  Purchase  Price.  The purchase price of Option Shares shall be 85% of
the lesser of (a) the Market Value of the shares as of the Offering Commencement
Date or (b) the Market Value of the shares as of the Offering Termination Date.

     9.3.  Restrictions on Transfer.  Options may not be assigned,  transferred,
pledged or otherwise disposed of. An Option may not be exercised by anyone other
than the Optionee during the lifetime of the Optionee.  Option Shares may not be
assigned, transferred, pledged or other disposed of, except by will or under the
laws of descent  and  distribution,  until  after the first  anniversary  of the
Offering  Termination  Date on which acquired (or the death of the Optionee,  if
earlier),   but  thereafter  may  be  sold  or  otherwise   transferred  without
restriction.  The Optionee shall agree in the Membership Agreement to notify the
Company  of  any  transfer  of the  Shares  within  two  years  of the  Offering
Commencement  Date of those Shares.  The Company shall have the right to place a
legend on all stock  certificates  instructing  the transfer agent to notify the
Company of any transfer of the shares.  The Company shall also have the right to
place a legend on certificates  setting forth the restriction on transferability
of such shares.



                                      -5-

     9.4.  Expiration.  Each Option shall expire at the close of business on the
Offering  Termination  Date  or on such  earlier  date as may  result  from  the
operation of Section 9.5.

     9.5.  Termination of Employment of Optionee.  If an Optionee ceases for any
reason to be continuously employed by a Participating  Employer,  whether due to
death,  retirement,  voluntary severance,  involuntary  severance,  transfer, or
disaffiliation  of a Related  Corporation  with the  Company,  his or her Option
shall immediately  expire,  and the Optionee's  accumulated  payroll  deductions
shall be returned to the Optionee or his or her Beneficiary, as the case may be,
by the Company. For purposes of this Section 9.5, an Optionee shall be deemed to
be employed  throughout  any leave of absence for military  service,  illness or
other bona fide  purpose  which does not exceed the longer of ninety days or the
period during which the Optionee's reemployment rights are guaranteed by statute
or by contract.  If the Optionee does not return to active  employment  prior to
the  termination of such period,  his or her employment  shall be deemed to have
ended on the ninety-first day of such leave of absence.

     9.6.  Capital Changes  Affecting the Stock. In the event that,  between the
Offering  Commencement  Date and the Offering  Termination  Date of an Option, a
stock  dividend  is paid or  becomes  payable  in  respect of the Stock or there
occurs a split-up or contraction in the number of shares of Stock, the number of
shares for which the Option may thereafter be exercised and the price to be paid
for each such share shall be proportionately  adjusted. In the event that, after
the Offering  Commencement  Date, there occurs a  reclassification  or change of
outstanding  shares of Stock or a consolidation or merger of the Company with or
into another  corporation or a sale of conveyance,  substantially as a whole, of
the  property of the  Company,  the  Optionee  shall be entitled on the Offering
Termination  Date to receive shares of stock or other  securities  equivalent in
kind and value to the shares of stock he or she would have held if he or she had
exercised the Option in full immediately prior to such reclassification, change,
consolidation,  merger, sale or conveyance and had continued to hold such shares
(together  with all other  shares and  securities  thereafter  issued in respect
thereof)  until the  Offering  Termination  Date.  In the event that there is to
occur a  recapitalization  involving  an  increase in the par value of the Stock
which  would  result  in a par  value  exceeding  the  exercise  price  under an
outstanding  Option,  the Company  shall  notify the  Optionee of such  proposed
recapitalization  immediately  upon its  being  recommended  by the Board to the
Company's  shareholders,  after  which  the  Optionee  shall  have the  right to
exercise his or her Option prior to such recapitalization; if the Optionee fails
to exercise the Option prior to  recapitalization,  the exercise price under the
Option shall be  appropriately  adjusted.  In the event that, after the Offering


                                      -6-
   7

Commencement  Date,  there occurs a dissolution  or  liquidation of the Company,
except  pursuant to a transaction  to which Section  424(a) of the Code applies,
each Option shall  terminate,  but the Optionee shall have the right to exercise
his or her Option prior to such dissolution or liquidation.

     9.7. Payroll  Deductions.  An Optionee may purchase shares under his or her
Option during any particular  Offering Period by completing and returning to the
personnel  department  of the  Company at least ten  business  days prior to the
beginning of such Offering Period a Membership Agreement indicating a percentage
(which shall be a full integer  between one and ten) of his or her  Compensation
which is to be withheld each pay period.  The Optionee shall not be permitted to
change the  percentage  of  Compensation  withheld  during an  Offering  Period.
However,  the Optionee  may  withdraw  all, but not less than all, of his or her
accumulated  payroll  deductions by submitting a written request therefor to the
personnel  department  of the  Company  no  later  than two  weeks  prior to the
Offering  Termination  Date  whereupon  his or her  payroll  deduction  for  the
remainder of the Offering Period shall cease. Any Membership Agreement in effect
for an Offering  Period  shall  remain in effect as to any  subsequent  Offering
Period unless  revoked by a withdrawal  of the  Optionee's  accumulated  payroll
deduction  amounts or modified by submission of a new Membership  Agreement,  or
until the Optionee's termination of employment for any reason.

     9.8. Exercise of Options. On the Offering Termination Date the Optionee may
purchase  the number of shares  purchasable  by his or her  accumulated  payroll
deductions,  or, if less,  the maximum number of shares subject to the Option as
provided in Section 9.1, provided that:

          (a) If the  total  number  of  shares  which  all  Optionees  elect to
     purchase,  together  with any  shares  already  purchased  under  the Plan,
     exceeds the total number of shares  which may be  purchased  under the Plan
     pursuant  to  Section  6, the  number  of shares  which  each  Optionee  is
     permitted to purchase  shall be decreased pro rata based on the  Optionee's
     accumulated  payroll  deductions  in  relation to all  accumulated  payroll
     deductions currently being withheld under the Plan.

          (b) If the  number of shares  purchasable  includes a  fraction,  such
     number shall be adjusted to the next smaller  whole number and the purchase
     price shall be adjusted accordingly.

Accumulated  payroll deductions not withdrawn prior to the Offering  Termination
Date shall be automatically applied by the Company toward the purchase of Option


                                      -7-
   8

Shares. Accumulated payroll deductions, to the extent in excess of the aggregate
purchase  price  of  the  shares  purchased  by  the  Optionee  on  an  Offering
Termination  Date, shall be refunded to the Optionee;  provided,  however,  that
where such excess is less than the purchase price for a single share of Stock on
such Date,  such excess shall not be refunded but instead  shall be carried over
and applied to the  purchase of shares in the first  following  Offering  Period
(subject to the  possibility  of  withdrawal  by the  Optionee in such Period in
accordance with the terms of the Plan).

     9.9. Delivery of Stock.  Except as provided below, within a reasonable time
after the Offering  Termination  Date,  the Company shall deliver or cause to be
delivered to the Optionee a certificate or certificates for the number of shares
purchased by the Optionee. A stock certificate representing the number of shares
purchased will be issued in the  participant's  name only, or if the Participant
so requests in writing,  not later than the Offering  Termination  Date,  in the
name of the  employee  and  another  person of legal age as joint  tenants  with
rights of  survivorship.  If any law or applicable  regulation of the Securities
and Exchange  Commission or other body having jurisdiction in the premises shall
require that the Company or the Optionee take any action in connection  with the
shares  being  purchased  under  the  Option,  delivery  of the  certificate  or
certificates for such shares shall be postponed until the necessary action shall
have been  completed,  which  action  shall be taken by the  Company  at its own
expense,  without  unreasonable  delay.  The Optionee  shall have no rights as a
shareholder  in  respect  of  shares  for  which  he or she has not  received  a
certificate.

     Notwithstanding  the  foregoing,  the  Company  may  elect  to hold for the
benefit of the  Optionee  any shares  otherwise  to be delivered to the Optionee
pursuant to this  Section 9.9, or to deliver the same to such agent or agents of
the Company for the benefit of the  Optionee as the Company may select,  for the
period  transfer of such shares is limited by this Plan (and  thereafter,  until
the Optionee  requests  delivery of such stock in writing).  In that event,  the
Optionee  shall have all of the rights of a shareholder in the shares so held by
the   Company  or  its  agent,   except  as  limited  by  the   restriction   on
transferability,  from and after the issuance of the same and the Company or its
agent shall adopt reasonable  procedures to enable the Optionee to exercise such
rights.  In the event of the Optionee's death while any shares are so held, such
shares shall be delivered to the Optionee's  Beneficiary  promptly following the
Committee's receipt of evidence  satisfactory to the Committee of the Optionee's
death.

     9.10.  Return of  Accumulated  Payroll  Deductions.  In the event  that the
Optionee or his or her  Beneficiary  is  entitled  to the return of  accumulated
payroll 


                                      -8-
   9

deductions,   whether  by  reason  of  voluntary   withdrawal,   termination  of
employment,  retirement,  death,  or  in  the  event  that  accumulated  payroll
deductions exceed the price of shares  purchased,  such amount shall be returned
by the Company to the Optionee or the  Beneficiary,  as the case may be, as soon
as practicable following the Offering Termination Date of the Offering Period in
which the same were deducted. Accumulated payroll deductions held by the Company
shall not bear interest nor shall the Company be obligated to segregate the same
from any of its other assets.

     10. No  Enlargement  of Employment  Rights.  Neither the  establishment  or
continuation of the Plan, nor the grant of any Option hereunder, shall be deemed
to give any  employee the right to be retained in the employ of the Company or a
Related Corporation,  or any successor to either, or to interfere with the right
of the Company or such Corporation or successor to discharge the employee at any
time.

     11.  Tax  Withholding.  If,  at  any  time,  the  Company  or  any  Related
Corporation is required, under applicable laws and regulations,  to withhold, or
to make any deduction  of, any taxes or take any other action in connection  any
exercise of an Option or transfer of shares of Common Stock, the Company or such
Related Corporation shall have the right to deduct from all amounts paid in cash
any taxes required by law to be withheld therefrom, and in the case of shares of
Common Stock, the Optionee or his or her estate or Beneficiary shall be required
to pay the Company or such Related  Corporation  the amount of taxes required to
be withheld,  or, in lieu thereof, the Company or such Related Corporation shall
have the right to retain,  or sell without notice, a sufficient number of shares
of Common Stock to cover the amount  required to be  withheld,  or to make other
arrangements with respect to withholding as it shall deem appropriate.

     12.  Governing  Law. The Plan and all Options and actions taken  thereunder
shall  be  governed  by  and  construed  in  accordance  with  the  laws  of the
Commonwealth of Massachusetts, without regard to the conflict of laws principles
thereof.
