                  2. Effective Date and Termination of Plan.
                     --------------------------------------

                  The Plan was approved by shareholders and became effective on
November 6, 2001. The Plan was amended and restated in its entirety on March 22,
2007. The Plan shall terminate on, and no Option shall be granted hereunder on
or after, the 10-year anniversary of the earlier of the approval of the Plan by
(i) the Board or (ii) the shareholders of the Bank; provided, however, that the
Board may at any time prior to that date terminate the Plan.

                  3. Administration of Plan.
                     ----------------------

                  The Plan shall be administered by the Committee appointed by
the Board. During any time that Shares are registered under the Securities Act,
the Committee shall consist of two or more individuals each of whom shall be a
"nonemployee director" as defined in Rule 16b-3 as promulgated by the Securities
and Exchange Commission ("Rule 16b-3") under the Exchange Act and shall, at such
times as the Company is subject to Section 162(m) of the Code (to the extent

the Code. The acts of a majority of the members present at any meeting of the
Committee at which a quorum is present, or acts approved in writing by a
majority of the entire Committee, shall be the acts of the Committee for
purposes of the Plan. If and to the extent applicable, no member of the
Committee may act as to matters under the Plan specifically relating to such
member. If no Committee is designated by the Board to act for these purposes,
the Board shall have the rights and responsibilities of the Committee hereunder.

                  4. Eligibility and Grant of Options; Committee Authority
                     -----------------------------------------------------

                  Subject to the provisions of the Plan, the Committee shall, in
its discretion as reflected by the terms of the Award Agreements: (i) authorize
the granting of Options to employees and directors of the Bank and the Company;
(ii) determine and designate from time to

                                       4
 6

time those employees and directors of the Bank and the Company to whom Options
are to be granted and the number of Shares to be optioned to each employee or
director; (iii) determine whether to grant Incentive Stock Options, or
Non-Qualified Stock Options, or both (to the extent that any Option does not
qualify as an Incentive Stock Option, it shall constitute a separate
Non-Qualified Stock Option); provided that Incentive Stock Options may only be
granted to employees; (iv) determine the time or times when and the manner and
condition in which each Option shall be exercisable and the duration of the
exercise period; and (v) determine or impose other conditions to the grant or
exercise of Options under the Plan as it may deem appropriate. In determining
the eligibility of an employee or director to receive an Option, as well as in
determining the number of Shares to be optioned to any employee or director, the
Committee may consider the position and responsibilities of the employee or
director, the nature and value to the Bank and the Company of the employee's or
director's services and accomplishments, the employee's or director's present
and potential contribution to the success of the Bank and the Company and such
other factors as the Committee may deem relevant. The Award Agreement shall
contain such other terms, provisions and conditions not inconsistent herewith as
shall be determined by the Committee. The Optionee shall take whatever
additional actions and execute whatever additional documents the Committee may
in its reasonable judgment deem necessary or advisable in order to carry out or
effect one or more of the obligations or restrictions imposed on the Optionee
pursuant to the express provisions of the Plan and the Award Agreement. The
Committee shall cause each Option to be designated as an Incentive Stock Option
or a Non-Qualified Stock Option.

                  5. Number of Shares Subject to Options.
                     -----------------------------------

                  Options with respect to an aggregate of no more than 400,000
Shares may be granted under the Plan. Notwithstanding the foregoing provision of
this Section 5, Shares as to which an Option is granted under the Plan that
remains unexercised at the expiration, forfeiture or other termination of such
Option may be the subject of the grant of further Options. Shares of Common
Stock issued hereunder may consist, in whole or in part, of authorized and
unissued shares or treasury shares. The certificates for Shares issued hereunder
may include any legend which the Committee deems appropriate to reflect any
rights of first refusal or other restrictions on transfer hereunder or under the
Award Agreement, or as the Committee may otherwise deem appropriate.

                  The aggregate Fair Market Value, determined as of the date an
Option is granted, of the Common Stock for which any Optionee may be awarded
Incentive Stock Options which are first exercisable by the Optionee during any
calendar year under the Plan (or any other stock option plan required to be
taken into account under Section 422(d) of the Code) shall not exceed $100,000.

                  6. Option Price.
                     ------------

                  The Option Price shall be determined by the Committee on the
date the Option is granted and reflected in the Award Agreement, as the same may
be amended from time to time. Any particular Award Agreement may provide for
different exercise prices for specified amounts of Shares subject to the Option.
The Option Price with respect to each Option shall not be less than 100% (or
110%, in the case of an individual described in Section 422(b)(6) of the Code
relating to certain 10% owners) of the Fair Market Value of a Share on the day
the Option is granted.

                  7. Period of Option and Vesting.
                     ----------------------------

                  (a) Unless earlier expired, forfeited or otherwise terminated,
each Option shall expire in its entirety upon the 10th anniversary of the date
of grant or shall have such other term as is set forth in the applicable Award
Agreement (except that, in the case of an individual described in Section
422(b)(6) of the Code (relating to certain 10% owners) who is granted an
Incentive Stock Option, the term of such Option shall be no more than five years
from the date of grant). The Option shall also expire, be forfeited and
terminate at such times and in such circumstances as otherwise provided
hereunder (including the forfeiture provisions of Section 9(b)) or under the
Award Agreement.

                  (b) Each Option, to the extent that there has been no
termination of the Optionee's employment or service as a director and the Option
has not otherwise lapsed, expired, terminated or been forfeited, shall first
become exercisable, unless otherwise set forth in the applicable Award
Agreement, as follows:

         For the Period Ending                 Percent of the Grant
         ---------------------                 --------------------
                                                   Exercisable
                                                   -----------

         First Anniversary of
         the date of Grant                           25%

         Second Anniversary of
         the date of Grant                           50%

         Third Anniversary of
         the date of Grant                           75%

         Fourth Anniversary of
         the date of Grant                           100%



Unless otherwise provided in the Award Agreement or herein, no Option (or
portion thereof) shall ever be exercisable if the Optionee's employment or
service as a director with the Bank or the Company has terminated before the
time at which such Option would otherwise have become exercisable, and any
Option that would otherwise become

                                       7
 9

exercisable after such termination shall not become exercisable and shall be
forfeited upon such termination. Notwithstanding the foregoing provisions of
this Section 7(b), Options exercisable pursuant to the schedule specified by the
Committee at the time of grant may be fully or more rapidly exercisable or
otherwise vested at any time in the discretion of the Committee. Upon and after
the death of an Optionee, such Optionee's Options, if and to the extent
otherwise exercisable hereunder or under the applicable Award Agreement after
the Optionee's death, may be exercised by the Successors of the Optionee.

                  8. Exercisability Upon and After Termination of Optionee.
                     -----------------------------------------------------

                  (a) Unless otherwise provided in the Award Agreement, if the
Optionee's employment or service as a director with the Bank or the Company is
terminated other than by termination by the Optionee or termination by the Bank
of the Company for Cause and other than by reason of death, Disability, or, in
the case of Non-Qualified Stock Options, Retirement, no exercise of an Option
may occur after the expiration of the 3-month period following the termination,
or if earlier, the expiration of the term of the Option as provided under
Section 7. Unless otherwise provided in the Award Agreement, if the Optionee's
employment or service as a director with the Bank or the Company is terminated
by reason of death, Disability, or, in the case of Non-Qualified Stock Options,
Retirement, no exercise of an Option may occur after the expiration of the
1-year period following the termination, or if earlier, the expiration of the
term of the Option as provided under Section 7.

                  (b) Notwithstanding any other provision hereof, unless
otherwise provided in the Award Agreement, if (i) the Optionee's employment or
service as a director is terminated by the Bank or the Company for Cause or (ii)
the Optionee voluntarily terminates employment or service as a director with the
Bank or the Company (other than on account of death, Retirement

                                       8
 10

or Disability) the Optionee's Options, to the extent then unexercised, shall
thereupon cease to be exercisable and shall be forfeited forthwith.

                  (c) Except as may otherwise be expressly set forth in this
Section 8, and except as may otherwise be expressly provided under the Award
Agreement, no provision of this Section 8 is intended to or shall permit the
exercise of the Option to the extent the Option was not exercisable upon
cessation of employment or service as a director.

                  9. Exercise of Options.
                     -------------------

                  (a) Subject to vesting and other restrictions provided for
hereunder or otherwise imposed in accordance herewith, an Option may be
exercised, and payment in full of the aggregate Option Price made, by an
Optionee only by written notice (in the form prescribed by the Committee) to the
Company specifying the number of Shares to be purchased.

                  (b) Without limiting the scope of the Committee's discretion
hereunder, the Committee may impose such other restrictions on the exercise of
Options (whether or not in the nature of the foregoing restrictions) as it may
deem necessary or appropriate.

                  (c) If Shares acquired upon exercise of an Incentive Stock
Option are disposed of in a disqualifying disposition within the meaning of
Section 422 of the Code by an Optionee prior to the expiration of either two
years from the date of grant of such Option or one year from the transfer of
Shares to the Optionee pursuant to the exercise of such Option, or in any other
disqualifying disposition within the meaning of Section 422 of the Code, such
Optionee shall notify the Company in writing as soon as practicable thereafter
of the date and terms of such disposition and, if the Company thereupon has a
tax-withholding obligation, shall pay to the Company an amount equal to any
withholding tax the Company is required to pay as a result of the disqualifying
disposition.

                  10. Payment.
                      -------

                  (a) The aggregate Option Price shall be paid in full upon the
exercise of the Option. Payment must be made by one of the following methods:

                  (i) a certified or bank cashier's check;

                  (ii) if approved by the Committee in its discretion, Shares of
                  previously owned Common Stock having an aggregate Fair Market
                  Value on the date of exercise equal to the aggregate Option
                  Price;

                  (iii) if approved by the Committee in its discretion, through
                  the written election of the Optionee to have Shares withheld
                  by the Company from the Shares otherwise to be received, with
                  such withheld Shares having an aggregate Fair Market Value on
                  the date of exercise equal to the aggregate Option Price; or

                  (iv) by any combination of such methods of payment or any
                  other method acceptable to the Committee in its discretion.


                  (b) The Committee, in its discretion, may also permit the
Optionee to elect to exercise an Option by receiving a combination of Shares and
cash, or, in the discretion of the Committee, either Shares or solely in cash,
with an aggregate Fair Market Value (or, to the extent of payment in cash, in an
amount) equal to the excess of the Fair Market Value of the Shares with respect
to which the Option is being exercised over the aggregate Option Price, as
determined as of the day the Option is exercised.

                  (c) Except in the case of Options exercised by certified or
bank cashier's check, the Committee may impose limitations and prohibitions on
the exercise of Options as it deems appropriate, including, without limitation,
any limitation or prohibition designed to avoid accounting consequences which
may result from the use of Common Stock as payment upon exercise of an Option.
Any fractional Shares resulting from an Optionee's election that is accepted by
the Company shall in the discretion of the Committee be paid in cash.

                                       10
 12

                  11. Tax Withholding.
                      ---------------

                  The Committee may, in its discretion, require the Optionee to
pay to the Company at the time of exercise of any Option the amount that the
Committee deems necessary to satisfy the Company's obligation to withhold
federal, state or local income or other taxes incurred by reason of the
exercise. Upon exercise of the Option, the Optionee may, if approved by the
Committee in its discretion, make a written election to have Shares then issued
withheld by the Company from the Shares otherwise to be received, or to deliver
previously owned Shares, in order to satisfy the liability for such withholding
taxes. In the event that the Optionee makes, and the Committee permits, such an
election, the number of Shares so withheld or delivered shall have an aggregate
Fair Market Value on the date of exercise sufficient to satisfy the applicable
withholding taxes. Where the exercise of an Option does not give rise to an
obligation by the Company to withhold federal, state or local income or other
taxes on the date of exercise, but may give rise to such an obligation in the
future, the Committee may, in its discretion, make such arrangements and impose
such requirements as it deems necessary or appropriate. Notwithstanding anything
contained in the Plan to the contrary, the Optionee's satisfaction of any
tax-withholding requirements imposed by the Committee shall be a condition
precedent to the Company's obligation as may otherwise be provided hereunder to
provide Shares to the Optionee, and the failure of the Optionee to satisfy such
requirements with respect to the exercise of an Option shall cause such Option
to be forfeited.

                  12. Exercise by Successors.
                      ----------------------

                  An Option may be exercised, and payment in full of the
aggregate Option Price made, by the Successors of the Optionee only by written
notice (in the form prescribed by the Committee) to the Company specifying the
number of Shares to be purchased. Such notice shall

                                       11
 13

state that the aggregate Option Price will be paid in full, or that the Option
will be exercised as otherwise provided hereunder, in the discretion of the
Company or the Committee, if and as applicable.

                  13. Nontransferability of Option.
                      ----------------------------

                  Each Option granted under the Plan shall by its terms be
nontransferable by the Optionee except by will or the laws of descent and
distribution of the state wherein the Optionee is domiciled at the time of his
or her death.

                  14. Right of First Refusal; Right of Repurchase; Transfer
                      -----------------------------------------------------
                      Restrictions.
                      ------------


                  a. At the time of grant, the Committee may provide in
connection with any grant made under the Plan that Shares received in connection
with Options shall be subject to a right of first refusal pursuant to which the
Company shall be entitled to purchase such Shares in the event of a prospective
sale of the Shares, subject to such terms and conditions as the Committee may
specify at the time of grant or (if permitted by the Award Agreement)
thereafter, and to a right of repurchase, pursuant to which the Company shall be
entitled to purchase such Shares at the Fair Market Value of the Shares (unless
otherwise provided in the Award Agreement), or, otherwise at a price determined
by, or under a formula set by, the Committee at the time of grant or (if
permitted by the Award Agreement) thereafter, subject to such other terms and
conditions as the Committee may specify at the time of grant.

                  b. Any Shares issued pursuant to an Option shall be subject to
such transfer restrictions as may be set forth in the Optionee's Award Agreement
(including, without limitation, the requirement that any Shares acquired prior
to the time such Shares are registered under the Securities Act, be assigned and
subject to a voting trust with terms determined by the Committee).

                  15. Regulations and Approvals.
                      -------------------------

                  (a) The obligation of the Company to sell Shares with respect
to Options granted under the Plan shall be subject to all applicable laws, rules
and regulations, including all applicable federal and state securities laws, and
the obtaining of all such approvals by governmental agencies as may be deemed
necessary or appropriate by the Committee.

                  (b) The Committee may make such changes to the Plan as may be
necessary or appropriate to comply with the rules and regulations of any
government authority or to obtain tax benefits applicable to stock options.

                  (c) Each Option is subject to the requirement that, if at any
time the Committee determines, in its discretion, that the listing, registration
or qualification of Shares issuable pursuant to the Plan is required by any
securities exchange or under any state or federal law, or the consent or
approval of any governmental regulatory body is necessary or desirable as a
condition of, or in connection with, the grant of an Option or the issuance of
Shares, no Options shall be granted or payment made or Shares issued, in whole
or in part, unless listing, registration, qualification, consent or approval has
been effected or obtained free of any conditions in a manner acceptable to the
Committee.

                  (d) In the event that the disposition of stock acquired
pursuant to the Plan is not covered by a then current registration statement
under the Securities Act, and is not otherwise exempt from such registration,
such Shares shall be restricted against transfer to the extent required under
the Securities Act, and the Committee may require any individual receiving
Shares pursuant to the Plan, as a condition precedent to receipt of such Shares,
to represent to the Company in writing that the Shares acquired by such
individual are acquired for investment only

                                       13

and not with a view to distribution and that such Shares will be disposed of
only if registered for sale under the Securities Act or if there is an available
exemption for such disposition.

                  16.  Administrative Rules; Interpretation.
                       ------------------------------------

                  The Committee may make such rules and regulations and
establish such procedures for the administration of the Plan as it deems
appropriate. Without limiting the generality of the foregoing, the Committee may
(i) determine (A) the conditions under which an Optionee will be considered to
have retired or become disabled and (B) whether any Optionee has done so; (ii)
establish or assist in the establishment of a program (which need not be
administered in a nondiscriminatory or uniform manner) under which the Bank or a
third party may make bona-fide loans on arm's-length terms to any or all
Optionees to assist such Optionees with the satisfaction of any or all of the
obligations that such Optionees may have hereunder or under which third-party
sales may be made for such purpose (including, without limitation, a broker
assisted cashless exercise where a third party would advance the aggregate
Option Price to the Optionee and be repaid with Option stock or the proceeds
thereof; (iii) determine the extent, if any, to which Options or Shares shall be
forfeited (whether or not such forfeiture is expressly contemplated hereunder);
(iv) interpret the Plan and the Award Agreements hereunder, with such
interpretations to be conclusive and binding on all persons and otherwise
accorded the maximum deference permitted by law; and (v) take any other actions
and make any other determinations or decisions that it deems necessary or
appropriate in connection with the Plan or the administration or interpretation
thereof. The Committee may in the Award Agreement provide that the Optionee
shall notify the Company of the failure to meet any holding period requirement
under the Code applicable to Shares received upon the exercise of an Incentive
Stock Option. Unless otherwise expressly provided hereunder, the Committee, with
respect to

                                       14
 16

any Option, may exercise its discretion hereunder at the time of the award or
thereafter. In the event of any dispute or disagreement as to the interpretation
of the Plan or of any rule, regulation or procedure, or as to any question,
right or obligation arising from or related to the Plan, the decision of the
Committee shall be final and binding upon all persons.

                  17. Amendments.
                      ----------

                  The Board may amend the Plan as it shall deem advisable,
except that no amendment may adversely affect an Optionee with respect to
Options previously granted unless such amendments are in connection with
compliance with applicable laws; provided that the Board may not make any
amendment in the Plan that would, if such amendment were not approved by the
holders of the Common Stock, cause the Plan to fail to comply with any
requirement of applicable law or regulation, unless and until the approval of
the holders of such Common Stock is obtained. Without limiting the generality of
the foregoing, the Committee may (subject to such considerations as may arise
under Section 16 of the Exchange Act, or under other corporate, securities or
tax laws) take any steps it deems appropriate, that are not inconsistent with
the purposes and intent of the Plan, or to take into account the provisions of
Section 162(m) of the Code.

                  18. Changes in Capital Structure.
                      ----------------------------

                  If (i) the Company shall at any time be involved in a merger,
consolidation, dissolution, liquidation, reorganization, exchange of shares,
sale of all or substantially all of the assets or stock of the Company or a
transaction similar thereto, (ii) any stock dividend, stock split, reverse stock
split, stock combination, reclassification, recapitalization or other similar
change in the capital structure of the Company, or any distribution to holders
of Common Stock other than cash dividends, shall occur or (iii) any other event
shall occur which in the judgment

                                       15
 17

of the Committee necessitates action by way of adjusting the terms of the
outstanding Options, then the Committee may forthwith take any such action as in
its judgment shall be necessary to preserve to the Optionees rights
substantially proportionate to the rights existing prior to such event, and to
maintain the continuing availability of Shares under Section 5 (if Shares are
otherwise then available) in a manner consistent with the intent hereof,
including, without limitation, adjustments in (x) the number and kind of shares
or other property subject to Options, (y) the Option Price, and (z) the number
and kind of shares available under Section 5. To the extent that such action
shall include an increase or decrease in the number of Shares (or units of other
property then available) subject to outstanding Options, the number of Shares
(or units) available under Section 5 shall be increased or decreased, as the
case may be, proportionately, as may be provided by the Committee in its
discretion.

                  If a Change in Control shall occur, then the Committee as
constituted immediately before the Change in Control may make such adjustments
as it, in its discretion, determines are necessary or appropriate in light of
the Change in Control (including, without limitation, the substitution of stock
other than stock of the Company as the stock optioned hereunder, and the
acceleration of the exercisability of the Options).

                  The judgment of the Committee with respect to any matter
referred to in this Section 18 shall be conclusive and binding upon each
Optionee without the need for any amendment to the Plan.

                      -------

                  All notices under the Plan shall be in writing, and if to the
Company, shall be delivered to the Board or mailed to its principal office,
addressed to the attention of the Board; and if to the Optionee, shall be
delivered personally, sent by facsimile transmission or mailed to the Optionee
at the address appearing in the records of the Company. Such addresses may be
changed at any time by written notice to the other party given in accordance
with this Section 19.

                  20. Rights as Shareholder.
                      ---------------------

                  Neither the Optionee nor any person entitled to exercise the
Optionee's rights in the event of death shall have any rights of a shareholder
with respect to the Shares subject to an Option, except to the extent that a
certificate for such Shares shall have been issued upon the exercise of the
Option as provided for herein.

                  21. Rights to Employment.
                      --------------------

                  Nothing in the Plan or in any Option granted pursuant to the
Plan shall confer on any individual any right to continue in the employ of the
Bank or the Company or to continue as a director of the Bank or the Company or
interfere in any way with the right of the Company and its shareholders to
terminate the individual's employment or service as a director at any time.

                  22. Exculpation and Indemnification.
                      -------------------------------

                  The Company shall indemnify and hold harmless the members of
the Board and the members of the Committee from and against any and all
liabilities, costs and expenses incurred by such persons as a result of any act
or omission to act in connection with the performance of such person's duties,
responsibilities and obligations under the Plan, to the maximum extent permitted
by law, other than such liabilities, costs and expenses as may result from the
negligence, bad faith, willful misconduct or criminal acts of such persons.

                      --------

                  The use of captions in this Plan is for convenience. The
captions are not intended to and do not provide substantive rights.

                  24. Severability.
                      ------------

                  The invalidity or unenforceability of any provision of the
Plan shall not affect the validity or enforceability of any other provision of
the Plan, which shall remain in full force and effect.

                  25. Governing Law.
                      -------------

                  The Plan shall be governed by the laws of Massachusetts,
without reference to principles of conflict of laws.
