                                   Granted by

                         BENJAMIN FRANKLIN BANCORP, INC.

                                    under the

            BENJAMIN FRANKLIN BANCORP, INC. 2006 STOCK INCENTIVE PLAN

This Option is and shall be subject in every respect to the provisions of 2006
Stock Incentive Plan, as amended from time to time (the "Plan"), of Benjamin
Franklin Bancorp, Inc. (the "Company"), which is incorporated herein by
reference and made a part hereof. A copy of the Plan is available for review at
the offices of the Company and a copy of the Plan has been provided to each
person granted an Option pursuant to the Plan. The holder of this Option (the
"Holder") hereby accepts this Option subject to all the terms and provisions of
the Plan and agrees that (a) in the event of any conflict between the terms
hereof and those of the Plan, the latter shall prevail, and (b) all decisions
under and interpretations of the Plan by the Board or the Committee shall be
final, binding and conclusive upon the Holder and the Holder's heirs, legal
representatives, successors and permitted assigns. 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").

1.    NAME OF HOLDER: _________________________________________________________

2.    DATE OF GRANT: __________________________________________________________

3.    NUMBER OF SHARES OF COMPANY COMMON STOCK, NO PAR VALUE ("COMMON STOCK")
      FOR WHICH THIS OPTION IS EXERCISABLE: ___________________________________
      (subject to adjustment pursuant to Section 11 below)

4.    EXERCISE PRICE PER SHARE: _______________________________________________
      (subject to adjustment pursuant to Section 11 below)

5.    EXPIRATION DATE OF OPTION: ______________________________________________

6.    VESTING SCHEDULE. Except as otherwise provided in this Agreement, this
      Option may be exercised prior to the Expiration Date in installments as
      follows:

            (i)   Twenty percent (20%) of the number of shares subject to the
                  foregoing grant on the first anniversary of the date of grant;
                  and

            (ii)  An additional twenty percent (20%) of the number of shares
                  subject to the foregoing grant on the dates which are the
                  second through fifth annual anniversaries of the date of
                  grant.

      The right of exercise shall be cumulative. This Option may not be
      exercised at any time on or after the Expiration Date. All vesting shall
      cease upon the date of termination of employment. Vesting will
      automatically accelerate pursuant to Sections 10.1(i), 12.1(i) and
      12.1(ii).



7.    INCENTIVE AND NONQUALIFIED OPTION. It is the intention of the Company that
      this option grant shall constitute an incentive stock option to the extent
      that, in the calendar year in which this option first becomes exercisable,
      the $100,000 limitation contained in Section 5.6 of the Plan would not be
      exceeded (taking into account all other incentive stock options of the
      Holder, if any, that first became exercisable prior thereto in the same
      calendar year). The portion of this option which is in excess of said
      $100,000 limitation shall constitute a nonqualified stock option.

8.    EXERCISE PROCEDURE.

      8.1. DELIVERY OF NOTICE OF EXERCISE. This Option shall be exercised in
whole or in part by the Holder's delivery to the Company of written notice (the
"Notice of Exercise") setting forth the number of shares with respect to which
this Option is to be exercised, together with payment by cash, a bank check or
other instrument acceptable to the Compensation Committee (the "Committee") in
an amount equal to the aggregate exercise price for the shares being purchased
upon exercise, or by one or more of the following methods, if permitted by the
Committee, in its discretion:

            (i)   by delivery to the Company of shares of Common Stock that are
                  not then subject to restrictions under any Company plan, which
                  have a Fair Market Value (as defined in Section 8.2) equal in
                  amount to the aggregate exercise price of the shares of Common
                  Stock being purchased upon such exercise,

            (ii)  by delivery to the Company of a properly executed Notice of
                  Exercise along with irrevocable instructions to a broker to
                  promptly deliver to the Company cash or a check payable and
                  acceptable to the Company to pay the aggregate exercise price,
                  provided that in the event the Holder chooses to pay the
                  purchase price as so provided, the Holder and the broker shall
                  comply with such procedures and enter into such agreements of
                  indemnity and other agreements as the Committee shall
                  prescribe as a condition of such payment procedure (including,
                  in the case of a Holder who is an executive officer of the
                  Company, such procedures and agreements as the Committee deems
                  appropriate in order to avoid any extension of credit in the
                  form of a personal loan to such officer). The Company need not
                  act upon such Notice of Exercise until the Company receives
                  full payment of the exercise price,

            (iii) by reducing the number of Option shares otherwise issuable to
                  the Holder upon exercise of the Option by a number of shares
                  having a Fair Market Value equal to such aggregate exercise
                  price, or

            (iv)  by delivery to the Company of such other consideration which
                  the Committee determines is consistent with the purpose of the
                  Plan and with applicable laws (including the Sarbanes-Oxley
                  Act of 2002) and regulations, or by any combination of the
                  means of payment.

      8.2. "FAIR MARKET VALUE" on any given date means the closing price per
share of the Common Stock on the trading day immediately preceding such date as
quoted on NASDAQ or, if applicable, as reported by such registered national
securities exchange on which the Common Stock is listed; provided, that, if
there is no trading on such date, Fair Market Value shall be deemed to be the
closing price per share on the last preceding date on which the Common Stock was
traded. If the Common Stock is not quoted on NASDAQ or listed on any registered
national securities exchange, the Fair Market Value of the Common Stock shall be
determined in good faith by the Committee.

9. DELIVERY OF COMMON STOCK; RESERVE.



      9.1. DELIVERY OF COMMON STOCK. As promptly as practicable after receipt by
the Company of the Notice of Exercise and payment of exercise price pursuant to
Section 8 hereof, the Company shall deliver to the Holder (or if any other
individual or individuals are exercising this Option, to such individual or
individuals) a certificate registered in the name of the Holder (or the names of
the other individual or individuals exercising this Option) and representing the
number of shares with respect to which this Option is then being exercised;
provided, however, that if any law or regulation or order of the Securities and
Exchange Commission or any other body having jurisdiction in the premises shall
require the Company or the Holder (or the individual or individuals exercising
this Option) to take any action in connection with the shares then being
purchased, the date for the delivery of the certificate for such shares shall be
extended for the period necessary to take and complete such action. The Company
may imprint upon said certificate such restrictive legends as the Committee
deems appropriate. Delivery by the Company of the certificates for such shares
shall be deemed effected for all purposes when the Company or a stock transfer
agent of the Company shall have deposited such certificates in the United States
mail, addressed to the Holder, at the Holder's last known address on file with
the Company. The Company will pay all fees or expenses necessarily incurred by
the Company in connection with the issuance and delivery of shares pursuant to
the exercise of this Option.

      9.2. RESERVE. The Company will, at all times while any portion of this
Option is outstanding, reserve and keep available, out of shares of its
authorized and unissued Common Stock or shares of Common Stock held in treasury,
a sufficient number of shares of its Common Stock to satisfy the requirements of
this Option.

10.   CHANGE IN CONTROL.

      10.1. In the event of a Change in Control while this Option is
unexercised, then

            (i)   the vesting of this Option shall be automatically accelerated,
                  effective as of the effective time of the Change in Control
                  (or thirty (30) days preceding the effective date of such
                  Change in Control, if the Committee cancels this Option
                  pursuant to Section 10.2 below), and

            (ii)  subject to Section 10.2 below, after the effective time of
                  such Change in Control, this Option shall remain outstanding
                  and shall be exercisable in full for shares of Common Stock
                  or, if applicable, for shares of such securities, cash or
                  property as the holders of shares of Common Stock received in
                  connection with such Change in Control.

      10.2. This Option may be cancelled by the Committee as of the effective
date of any Change in Control provided that (x) prior written notice of such
cancellation shall be given to the Holder and (y) the Holder shall have the
right to exercise this Option in full during the thirty (30) day period
preceding the effective date of such Change in Control.

      10.3. "Change in Control" shall mean the occurrence of any one of the
following events:

            (i)   If there has occurred a change in control which the Company
                  would be required to report in response to Item 5.01 of Form
                  8-K promulgated under the Securities Exchange Act of 1934, as
                  amended (the "1934 Act"), or, if such regulation is no longer
                  in effect, any regulations promulgated by the Securities and
                  Exchange Commission pursuant to the 1934 Act which are
                  intended to serve similar purposes;

            (ii)  When any "person" (as such term is used in Sections 13(d) and
                  14(d)(2) of the 1934 Act) becomes a "beneficial owner" (as
                  such term is defined in Rule 13d-3



                  promulgated under the 1934 Act), directly or indirectly, of
                  securities of the Company or Benjamin Franklin Bank (the
                  "Bank") representing twenty-five percent (25%) or more of the
                  total number of votes that may be cast for the election of
                  directors of the Company or the Bank, as the case may be;

            (iii) During any period of two consecutive years, individuals who at
                  the beginning of such period constitute the Board of Directors
                  of the Company, and any new director (other than a director
                  designated by a person who has entered into an agreement with
                  the Company to effect a transaction described in Subsection
                  (ii), (iv) or (v) of this Section 10.3) whose election by the
                  Board or nomination for election by the Company's stockholders
                  was approved by a vote of at least two-thirds (2/3) of the
                  directors then still in office who either were directors at
                  the beginning of the period or whose election or nomination
                  for election was previously so approved, cease for any reason
                  to constitute at least a majority of the Board of Directors of
                  the Company;

            (iv)  The stockholders of the Company approve a merger, share
                  exchange or consolidation ("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 70% 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 30% of the combined
                  voting power of the Company's then outstanding securities; or

            (v)   The stockholders of the Company or the Bank approve a plan of
                  complete liquidation of the Company or the Bank or an
                  agreement for the sale or disposition by the Company or the
                  Bank of all or substantially all of the Company's or the
                  Bank's assets.

11. ADJUSTMENT PROVISIONS.

      11.1. GENERAL. If the Company effects a stock dividend, stock split or
similar change in capitalization affecting the Common Stock, the Committee will
make appropriate adjustments in (i) the number and kind of shares subject to
this Option, and (ii) the option or purchase price in respect of such shares.

      11.2. MERGERS, CONSOLIDATION, DISTRIBUTIONS, LIQUIDATIONS. In the event of
any merger, consolidation, dissolution or liquidation of the Company, the
Committee in its sole discretion may make such substitution or adjustment in the
number and purchase price of shares subject to this Option as it may determine
and as may be permitted by the terms of such transaction, or accelerate, amend
or terminate this Option upon such terms and conditions as it shall provide
(which, in the case of the termination of the vested portion of this Option,
shall require payment or other consideration which the Committee deems equitable
in the circumstances, subject, however, to the provisions of Section 10).

12. TERMINATION OF OPTION.

      12.1. This Option shall terminate upon the Expiration Date, or earlier as
follows:



            (i)   DEATH. This Option shall vest and become exercisable in full
                  if the Holder's employment with the Company is terminated by
                  reason of the Holder's death while this option is unexercised.
                  This Option may thereafter be exercised by the legal
                  representative or legatee of the Holder for a period of one
                  year from the date of death, subject to termination on the
                  Expiration Date of this Option, if earlier.

            (ii)  DISABILITY. This Option shall vest and become exercisable in
                  full if the Holder's employment with the Company is terminated
                  by reason of Disability (as defined in the Plan) while this
                  option is unexercised. This Option may thereafter be exercised
                  for a period of one year from the date of such termination of
                  employment by reason of Disability, subject to termination on
                  the Expiration Date, if earlier. The death of the Holder
                  during the one-year period for exercise of this Option
                  provided in this Section 12.1(ii) shall extend such period for
                  one year from the date of death, subject to termination on the
                  Expiration Date, if earlier. The Committee shall have sole
                  authority and discretion to determine whether the Holder's
                  employment has been terminated by reason of Disability.

            (iii) NORMAL RETIREMENT. If the Holder's employment with the Company
                  terminates by reason of Normal Retirement (as defined in the
                  Plan) while this Option is unexercised, this Option may
                  thereafter be exercised, to the extent it was vested and
                  exercisable at the time of such termination of employment, for
                  a period of ninety (90) days from the date of such termination
                  of employment, subject to termination on the Expiration Date,
                  if earlier. The death of the Holder during the ninety-day
                  period for the exercise of this Option provided in this
                  Section 12.1(iii) shall extend such exercise period for one
                  year from the date of death, subject to termination on the
                  Expiration Date, if earlier. The Committee shall have sole
                  authority and discretion to determine whether the Holder's
                  employment has been terminated by reason of Normal Retirement.

            (iv)  TERMINATION FOR CAUSE. If the Holder's employment by the
                  Company has been terminated for Cause (as defined in the
                  Plan), this Option shall immediately terminate and be of no
                  further force and effect; provided, however, that the
                  Committee may, in its sole discretion, provide that such
                  Option can be exercised for a period of up to ninety (90) days
                  from the date of termination of employment, subject to
                  termination on the Expiration Date, if earlier. The Board of
                  Directors shall have sole authority and discretion to
                  determine whether the Holder's employment has been terminated
                  for Cause.

            (v)   OTHER TERMINATION. If the Holder's employment by the Company
                  terminates for any reason other than death, Disability, Normal
                  Retirement or for Cause, this Option may thereafter be
                  exercised, to the extent it was exercisable at the time of
                  such termination, for a period of thirty (30) days from the
                  last day of the Holder's employment, subject to termination on
                  the Expiration Date, if earlier.

13.   DISQUALIFYING DISPOSITION.

      13.1. DISQUALIFYING DISPOSITION. The Holder agrees to notify the Company
in writing immediately after making a Disqualifying Disposition of any shares of
Common Stock received pursuant to the exercise of this Option. A "Disqualifying
Disposition" shall have the meaning specified in Section 421(b) of the Code; as
of the date of grant of this Option a Disqualifying Disposition is any
disposition (including any sale) of such shares before the later of (a) the
second anniversary of the date of grant of this Option and (b) the first
anniversary of the date on which the Holder acquired such shares by



exercising this Option, provided that such holding period requirements terminate
upon the death of the Holder. The Holder also agrees to provide the Company with
any information that the Company shall request concerning any such Disqualifying
Disposition. The Holder acknowledges that he or she will forfeit the favorable
income tax treatment otherwise available with respect to the exercise of this
Option if he or she makes a Disqualifying Disposition of shares received upon
exercise of this Option.

      13.2. ADDITIONAL WITHHOLDING. The Holder hereby agrees that the Company
may withhold from the Holder's wages, or other amounts due to the Holder from
the Company, the appropriate amount of federal, state and local withholding
taxes attributable to the Holder's exercise of this Option. At the Holder's
election (with the consent of the Committee), the amount required to be withheld
may be satisfied, in whole or in part, by (i) authorizing the Company to
withhold from shares of Common Stock to be issued pursuant to the exercise of
this Option a number of shares with an aggregate Fair Market Value (as defined
in Section 8.2) (as of the date the withholding is effected) that would satisfy
the minimum withholding amount due with respect to such exercise, or (ii)
delivering to the Company a number of shares of Stock with an aggregate Fair
Market Value (as of the date the withholding is effected) that would satisfy the
minimum withholding amount due.

      13.3. REIMBURSEMENT. The Holder further agrees that, if the Company does
not withhold an amount from the Holder's wages sufficient to satisfy the
Company's withholding obligation, the Holder will reimburse the Company on
demand, in cash, for the amount underwithheld.

14. MISCELLANEOUS.

      14.1. Neither the Holder nor any other person shall, by virtue of the
granting of this Option, be deemed for any purpose to be the owner of any shares
of Common Stock subject to this Option or to be entitled to the rights or
privileges of a holder of such shares unless and until this Option has been
exercised pursuant to the terms hereof with respect to such shares and the
Company has issued and delivered the shares to the Holder.

      14.2. This Option is not transferable other than by will or by the laws of
descent and distribution, and is exercisable, during the Holder's lifetime, only
by the Holder.

      14.3. Any notice to be given to the Company hereunder shall be deemed
sufficient if addressed to the Company and delivered at the office of the
President of the Company, or such other address as the Company may hereafter
designate, or when deposited in the mail, postage prepaid, addressed to the
attention of the President of the Company at such office or other address.

      14.4. Any notice to be given to the Holder hereunder shall be deemed
sufficient if addressed to and delivered in person to the Holder at his address
furnished to the Company or when deposited in the mail, postage prepaid,
addressed to the Holder at such address.

      14.5. This Option shall be governed by and construed in accordance with
the laws of The Commonwealth of Massachusetts, without regard to its principles
of conflicts of laws.

      14.6. In the case of a partial exercise of this Option the Holder shall
surrender his copy hereof and such partial exercise shall be noted thereon, if
the Company so requests.

      14.7. This Option is subject to all laws, regulations and orders of any
governmental authority which may be applicable thereto and, notwithstanding any
of the provisions hereof, the Holder agrees that he will not exercise the Option
granted hereby nor will the Company be obligated to issue any shares of



stock hereunder if the exercise thereof or the issuance of such shares, as the
case may be, would constitute a violation by the Holder or the Company of any
such law, regulation or order or any provision thereof.

      14.8. The granting of this Option does not confer upon the Holder any
right to continued employment with the Company or any subsidiary.

      IN WITNESS WHEREOF, the Company has caused this instrument to be executed
in its name and on its behalf as of the date of grant of this Option set forth
above.
