                          SPECIAL TERMINATION AGREEMENT

     THIS AGREEMENT, dated as of August 10, 2006 (the "Agreement"), is by and
among LSB CORPORATION, a Massachusetts corporation (the "Company") and its
wholly owned subsidiary, RIVER BANK, a Massachusetts savings bank with its
executive offices in North Andover, Massachusetts (the "Bank") (the Bank and the
Company shall be hereinafter collectively referred to as the "Employers"), and
Gerald T. Mulligan, (the "Executive"), an individual presently employed by the
Company and the Bank in the capacity of President and Chief Executive Officer.

     1. Purpose. In order to allow the Executive to consider the prospect of a
Change in Control (as defined in Section 2) in an objective manner and in
consideration of the services rendered and to be rendered by the Executive to
the Employers and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by the Executive and the Employers,
the Employers are willing to provide, subject to the terms of this Agreement,
certain severance benefits to protect the Executive from the consequences of a
Terminating Event (as defined in Section 3) occurring subsequent to a Change in
Control.

     2. Change in Control. A "Change in Control" shall be deemed to have
occurred upon the occurrence of any of the following events:

     (i)  any circumstance that the Company or the Bank would be required to
          report as a change in control under Item 5.01 of the Current Report on
          Form 8-K as prescribed by applicable regulations promulgated under the
          Securities Exchange Act of 1934, as amended (the "1934 Act"), or any
          successor provision; or

     (ii) 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 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 (other than in the
          case of the Bank, for the Company's ownership of the capital stock of
          the Bank), and the Board of Directors of the Company or the Bank, as
          the case may be, has not consented to such event by a two-thirds (2/3)
          vote of all of the members of the Board of Directors adopted either
          prior to such event or within sixty (60) days thereafter, provided
          that if at the time such a consent vote is adopted after such event,
          the persons who were directors of the Company or the Bank, as the case
          may be, immediately prior to such event do not constitute a majority
          of the Board of Directors of the Company or the Bank, respectively, or
          of any successor institution, such vote shall not be deemed to
          constitute consent for the purposes of this provision; or

     (iii) any tender or exchange offer for the ordinary voting stock of the
          Company or the Bank, or any merger, consolidation, or other business
          combination involving the Company or the Bank, or any sale or other
          disposition of assets of the Company or the Bank constituting all or
          substantially all of the Company's assets

<PAGE>

          (considered a consolidated basis), or any combination of the foregoing
          transactions has occurred, and as the result of, or in connection
          with, such transaction(s) (A) the individuals who were directors of
          the Company or the Bank immediately before the commencement of such
          transaction(s) cease to constitute a majority of the Board of
          Directors of the Company or the Bank, respectively, or of any
          successor institution or (B) persons, who, immediately prior to the
          commencement of such transaction(s), were the beneficial owners of
          ordinary voting stock of the Company or the Bank, beneficially own
          (within the meaning of Rule 13d-3), directly or indirectly, less than
          forty percent (40%) of the then outstanding shares of ordinary voting
          stock of the entity resulting from such transaction(s), including,
          without limitation, an entity which as a result of such transaction(s)
          owns the Company or the Bank or all or substantially all of the assets
          of the Company or the Bank either directly or through one or more
          subsidiaries; or

     (iv) during any period of two consecutive years, individuals who constitute
          the Board of Directors of the Company at the beginning of the two-year
          period cease for any reason to constitute at least a majority of the
          Company's directors; provided, however, that for purposes of this
          clause, an individual shall be deemed to have also been a director at
          the beginning of such period if such individual was elected by the
          Company's Board of Directors (or nominated by the Company's Board of
          Directors of the Company for election by the stockholders) by a vote
          of at least two-thirds (2/3) of the directors who either were
          directors at the beginning of the two-year period or who were so
          elected or nominated by such directors.

     3. Terminating Event; Cause; Good Reason; Disability.

          a. As used in this Agreement, the phrase "Terminating Event" shall
mean the occurrence, after a Change in Control, of (a) termination by either of
the Employers of the employment of the Executive with either of the Employers
for any reason other than (i) death, (ii) Disability (as defined in this
Section), or (iii) Cause (as defined in this Section), or (b) resignation of the
Executive from the employ of either of the Employers for Good Reason (as defined
in this Section), while the Executive is not receiving disability payments or
benefits from the Employers.

          b. As used in this Agreement, the term "Cause" shall mean the

     (ii) has committed an act of fraud, embezzlement, theft, or has committed
          any other act which has resulted in the termination of coverage under

          from termination of coverage as to the Employer as a whole); or


                                        2

<PAGE>

     (iii) has committed a willful violation of the Bank's Code of Conduct or
          any law, rule or regulation governing the operation of the Company or
          the Bank or any of its affiliates or the insurance of deposits held by
          the Bank (A) which is a felony or misdemeanor, or (B) which the Board
          of Directors of either of the Employers determines in good faith, by
          the affirmative vote of at least two-thirds (2/3) of the then current
          directors, has had or will likely have a material adverse effect on
          the business, interests or reputation of the Employers or any of their
          affiliates; or

     (iv) has committed any act which the Board of Directors of either of the
          Employers determines in good faith, by the affirmative vote of at

          a willful or reckless breach of fiduciary duty to the Company or the
          Bank or any of their affiliates involving personal profit to the
          Executive or any of the Executive's family members, associates or
          affiliates and (B) that such breach, together with all consequences
          related thereto, has had or will likely have a material adverse effect
          on the business, interests or reputation of the Employers or any of
          their affiliates or on the Executive's ability to perform the duties
          reasonably assigned to the Executive; or

     (v)  has been convicted of any crime, or has entered a plea of nolo
          contendere to such an offense, or has committed any other act, in each
          case which the Board of Directors of either of the Employers
          determines in good faith, by the affirmative vote of at least
          two-thirds (2/3) of the then current directors, is (A) abhorrent to
          the community and (B) will likely have a material adverse effect on
          the business, interests or reputation of the Employers or the
          Executive's ability to perform the duties reasonably assigned to the
          Executive; or

     (vi) has committed a willful and unauthorized disclosure of material
          confidential information regarding the Employers or any of their
          affiliates, which disclosure the Board of Directors of either of the
          Employers determines in good faith, by the affirmative vote of at
          least two-thirds (2/3) of the then current directors, has had or will
          likely have a material adverse effect on the business, interests or
          reputation of the Employers or any of their affiliates; or

     (vii) has been found by the Board of Directors of either of the Employers,
          acting in good faith by the affirmative vote of at least two-thirds
          (2/3) of the then current directors, after reasonable written notice
          to the Executive and an opportunity to cure, to have a dependency on
          alcohol or other drugs that substantially interferes with the
          Executive's performance of duties reasonably assigned to the
          Executive.

          c. As used in this Agreement, the term "Good Reason" shall mean

     (i)  A significant and, from the Executive's perspective, adverse change in
          the nature or scope of the Executive's responsibilities, authorities,
          powers, functions or duties from the responsibilities, authorities,
          powers, functions or duties exercised by the Executive immediately
          prior to the Change in Control (or at the Executive's election, prior
          to the earlier commencement of the Proposed Business Combination that
          results in such Change in Control); or


                                        3

<PAGE>

     (ii) A reasonable determination by the Executive that, as a result of a
          Change in Control, the Executive is unable to exercise the
          responsibilities, authorities, powers, functions or duties exercised
          by the Executive immediately prior to such Change in Control (or at
          the Executive's election, prior to the earlier commencement of the
          Proposed Business Combination that results in such Change in Control);
          or

     (iii) Any decrease in the Executive's base salary or any decrease of five
          percent (5%) or more in the total annual compensation payable by the
          Employers to the Executive as compared to the Executive's base salary
          or total annual compensation target immediately prior to the Change in
          Control (or at the Executive's election, prior to the earlier
          commencement of the Proposed Business Combination that results in such
          Change in Control); provided, however, that a decrease in base salary
          or total compensation payable to the Executive and to all other
          executive officers of the Employers on a comparable basis as a result
          of the Employers' financial performance shall not constitute Good
          Reason; or

     (iv) The failure by the Employers to continue the Executive's participation
          in any material compensation, incentive, bonus or benefit plan,
          including life, medical and disability coverage, in which the
          Executive participates immediately prior to the Change in Control (or
          at the Executive's election, prior to the earlier commencement of the
          Proposed Business Combination that results in such Change in Control),
          or in any successor plan, or the taking of any action by the Employers
          that would reduce, directly or indirectly, in any material respect any
          of such benefits or deprive the Executive of any material fringe
          benefit enjoyed by the Executive under such plan at the time of the
          Change in Control (or at the Executive's election, prior to the
          earlier commencement of the Proposed Business Combination that results
          in such Change in Control), or any successor plan (except to the
          extent any benefits or coverage under such plans may be changed in its
          application to all of the employees of the Employers (or
          successors-in-interest) on a nondiscriminatory basis), or the failure
          of a successor-in-interest to make available its benefits plans to the
          Executive on a basis that is not substantially less favorable than the
          successor generally affords to its other employees holding similar
          positions; or

     (v)  The relocation of the Employers' offices at which the Executive is
          principally employed immediately prior to the Change in Control, or at
          the Executive's election, the earlier commencement of the Proposed
          Business Combination that results in such Change in Control, to a
          location more than 25 miles from such office or from North Andover,
          Massachusetts, or either of the Employers requiring the Executive to
          be based anywhere other than the Employers' executive offices, except
          for required travel on the Employers' business to an extent
          substantially consistent with customary business travel obligations;
          or

     (vi) The failure of either of the Employers to obtain a satisfactory
          agreement from any successor to assume and agree to perform this
          Agreement as required by Section


                                        4

<PAGE>

          16 hereof, after written notice from the Executive that makes
          reference to this provision and provides a reasonable opportunity to
          cure.

     For purposes of this Agreement, the term "Business Combination" shall mean
any tender or exchange offer for the ordinary voting stock of the Company or the
Bank, or any merger, consolidation, or other business combination involving the
Company or the Bank, or any sale or other disposition of assets of the Company
or the Bank constituting all or substantially all of the Company's assets
(considered a consolidated basis). A "Proposed Business Combination" shall mean
the occurrence of the Company or the Bank entering into a definitive agreement
providing for a Business Combination that, as the result of or in connection
with such transaction or any combination of related transactions, will result in
a Change in Control.

          d. For purposes of this Agreement, the Executive shall be deemed to be
subject to a Disability if the Executive is permanently disabled within the
meaning of the Employers' long-term disability policy, or if there is no such
policy, if the Executive is unable, through physical or mental illness or other
cause, to perform normal and customary duties which the Executive reasonably is
required to perform for the Employers, for a total of six (6) months during any
one (1) year period. In determining whether the Executive is disabled, the
Employers may rely upon the written statement provided by a licensed physician
reasonably acceptable to the Employers and the Executive. The Executive shall
allow examination from time to time by any licensed physician selected by the
Employers and reasonably acceptable to the Executive. All such examinations will
be conducted at or in a reasonable place, time and manner.

     4. Severance Payment. Subject to the provisions of Section 6 below and the
Executive signing the Employers' standard separation agreement, which includes,
among other provisions, a General Release, in the event a Terminating Event
occurs within two (2) years after a Change in Control, the Employers shall pay
to the Executive an aggregate amount (the "Severance Payment") equal to (x)
three (3) times the "base amount" (as defined in Section 280G(b)(3) of the
Internal Revenue Code of 1986, as amended (the "Code")) applicable to the
Executive, less (y) any other payment or benefit received by the Executive from
the Employers or either of them that is deemed to constitute a "parachute
payment" as defined in Section 280G of the Code, and less (z) One Dollar
($1.00). The Severance Payment shall be payable by the Employers in one lump sum
on the effective date of such Terminating Event.

     5. Benefit Continuation. If a Terminating Event occurs within two years
after a Change in Control, the Employers shall continue to provide to the
Executive, for three (3) years after the Terminating Event, the life, medical
and disability coverage in which the Executive participated, and at the level in
effect, and at the same out-of-pocket cost to the Executive, immediately prior
to the Change in Control, or at the Executive's election, the earlier
commencement of the Proposed Business Combination that results in such Change in
Control (except to the extent any benefit or coverage under such plans may be
changed in its application to all of the employees of the Employers (or
successors-in-interest) on a nondiscriminatory basis). If the Employers are
unable to provide the benefits set forth in this Section 5 due to the change in
Executive's status to that of a non-employee, the Employers shall instead pay to
the Executive a lump sum amount equal to the value of the benefits required to
be provided by this Section 5.


                                        5

<PAGE>

     6. Limitation on Benefits.

          (a) It is the intention of the Executive and of the Employers that no
payment by the Employers to or for the benefit of the Executive under this
Agreement and/or any other agreement or plan pursuant to which the Executive is
entitled to receive payments or benefits shall be non-deductible to the
Employers by reason of the operation of Section 280G of the Code relating to
parachute payments. Accordingly, and notwithstanding any other provision of this
Agreement or any such agreement or plan, if by reason of the operation of said
Section 280G, any such payments exceed the amount which can be deducted by the
Employers in the aggregate, such payments shall be reduced to the maximum amount
which can be deducted by the Employers. To the extent that payments exceeding
such maximum deductible amount have been made to or for the benefit of the
Executive, such excess payments shall be refunded to the Employers with interest
thereon at the applicable Federal Rate determined under Section 1274(d) of the
Code, compounded annually, or at such other rate as may be required in order
that no such payments shall be non-deductible to the Employers by reason of the
operation of said Section 280G. To the extent that there is more than one method
of reducing the payments to bring them within the limitations of said Section
280G, the Executive shall determine which method shall be followed, provided
that if the Executive fails to make such determination within forty-five days
(45) after the Employers have sent him written notice of the need for such
reduction, the Employers may determine the method of such reduction in their
sole discretion.

          (b) If any dispute between the Employers and the Executive as to any
of the amounts to be determined under Section 6(a), or the method of calculating
such amounts, cannot be resolved by the Employers and the Executive, either the
Employers or the Executive after giving three (3) days written notice to the
other, may refer the dispute to a partner in the Boston office of a firm of
nationally recognized independent certified public accountants selected jointly
by the Employers and the Executive, which firm shall not be the Employers'
independent registered public accounting firm. The determination of such partner
as to the amount to be determined under Section 6(a) and the method of
calculating such amounts shall be final and binding on both the Employers and
the Executive. The Employers shall bear the costs of any such determination.

          (c) This Agreement is intended to be construed in a manner to avoid
imposition on payments hereunder of interest and additional tax under Section
409A(a)(1)(B) of the Code. Without limiting the scope of the previous sentence,
with respect to any payment hereunder subject to Section 409A, distributions on
account of a separation from service may not be made to the Executive if he is a
"Specified Employee" within the meaning of Section 409A(a)(2)(B)(i) before the
date which is six (6) months after the date after separation from service (or,
if earlier, the date of death of the Executive).

     7. Employment Status. This Agreement is not an agreement for the employment
of the Executive and shall confer no rights on the Executive except as herein
expressly provided.

     8. Term. This Agreement shall take effect August 10, 2006, and shall
terminate upon the earlier of (a) the termination by the Employers of the
employment of the Executive because of death, Disability (as defined in Section
3(d) hereof) or Cause (as defined in Section 3(b) hereof), (b) the resignation
or termination by the Executive for any reason prior to a Change


                                        6

<PAGE>

in Control, or (c) the resignation of the Executive after a Change in Control
other than for Good Reason (as defined in Section 3(c) hereof).

     9. Withholding. All payments made by the Employers under this Agreement
shall be net of any tax or other amounts required to be withheld by the
Employers under applicable law.

     10. Mitigation. The Executive shall have no obligation to mitigate the
consequences of a termination by the Employers of the Executive's employment
without Cause or the Executive's resignation for Good Reason, and neither the
Severance Payment nor benefits provided under Section 5 (or the lump sum payment
is lieu of some or all of such benefits) shall be reduced or otherwise modified
as a result of the Executive obtaining other employment after such a termination
or resignation.

     11. Confidentiality. The Executive understands and agrees (a) that the
Executive will maintain all proprietary and confidential information of the
Employers as proprietary and confidential at all times during and after his/her
employment, (b) that the Executive will not disclose or communicate such
information to any third party or make use of it on his/her own behalf or on
behalf of any third party, and (c) upon his/her termination, that the Executive
will deliver all tangible forms or media which the Executive may have containing
such information to the Employers. For purposes of this Section 11,
"information" includes trade secrets and all non-public records, practices,
letters, plans, drawings, computer programs and data, technical data, financial
and other business data pertaining to the Employers or either of them or any of
their affiliates, customers, vendors or other persons associated with the Bank.
The Executive acknowledges and further agrees that the disclosure of such
information would be a material breach of this Agreement for which the Bank
shall be entitled to any remedies available to it in law or in equity.

     12. Covenant Not to Disrupt Business. The Executive hereby covenants and
agrees that he or she will not now, or for a period of one (1) year after the
effective date of the Executive's termination of employment, whether or not
following a Change in Control, disrupt, damage, impair or interfere with the
business of the Employers or either of them or any of their affiliates, whether
by way of interfering with or soliciting its employees (other than a general
solicitation not targeted at the Employers' employees), or disrupting either of
the Employers' or any of their affiliates' relationships with any customer, loan
packager, representative, vendor, broker or similar party doing business with
the Employer. After termination of employment, whether or not following a Change
in Control, the Executive is not, however, restricted from being employed by or
engaged in a competing business, except as may be provided expressly in any
other written agreement to which the Executive and the Employers or either of
them is a party.

     13. Arbitration of Disputes. Any controversy or claim arising out of or
relating to this Agreement or the breach thereof shall be settled by arbitration
in accordance with the laws of the Commonwealth of Massachusetts by three
arbitrators, one of whom shall be appointed by the Employers, one by the
Executive and the third by the first two arbitrators. If the first two
arbitrators cannot agree on the appointment of a third arbitrator, then the
third arbitrator shall be appointed by the American Arbitration Association in
the City of Boston. Such arbitration shall


                                        7

<PAGE>

be conducted in the City of Boston in accordance with the rules of the American
Arbitration Association, except with respect to the selection of arbitrators
which shall be as provided in this Section 13. Judgment upon the award rendered
by the arbitrators may be entered in any court having jurisdiction thereof. This
provision shall not apply to Section 6(b), except in the event that the
Employers and the Executive cannot agree on the selection of the accounting
partner described in said section.

     14. Payment of Costs and Legal Fees. All reasonable costs and legal fees
paid or incurred by the Executive pursuant to any dispute or question of
interpretation relating to this Agreement shall be paid or reimbursed by the
Employers, plus interest on any delayed payment at the rate provided for in
Section 7872(f)(2)(A) of the Code or any successor provision, unless (A) the
Executive is wholly unsuccessful on the merits of such dispute or question of
interpretation, as determined pursuant to a legal judgment, arbitration award or
settlement (whether formal or informal) or (B) unless and to the extent the
arbitrators shall determine that under the circumstances recovery by the
Executive of all or a part of any such fees and costs and expenses would be
unjust.

     15. Cooperation Covenant. Both during and after the Executive's employment,
the Executive shall cooperate fully with the Employers and with any legal
counsel, expert or consultant the Employers or either of them may retain to
assist in connection with any judicial proceedings, arbitration, administrative
proceeding, governmental investigation, examination, inquiry or internal audit
in which the Employers or either of them or any of their affiliates, may be or
become involved, including full disclosure of all relevant information and
truthfully testifying on the Employers' behalf (or, at the request of the
Employers, on behalf of any such affiliate of the Employers) in connection with
any such proceeding or investigation.

     16. Assignment; Successors and Assigns.

     a. The Executive may not make any assignment of this Agreement or any
interest herein, by operation of law or otherwise, without the prior written
consent of the Employers.

     b. This Agreement shall inure to the benefit of and be binding upon the
Employers and the Executive, their respective successors, executors,
administrators, heirs and permitted assigns. In the event of the Executive's
death prior to the completion by the Employers of all payments due to the
Executive under this Agreement, the Employers shall continue such payments to
the Executive's beneficiary designated in writing to the Employers prior to the
Executive's death (or to the Executive's estate, if the Executive fails to make
such designation).

     c. Each of the Employers shall require their respective successors (whether
direct or indirect, by purchase, merger, consolidation, or otherwise) to all or
substantially all of their business and/or assets to expressly assume and agree
to perform this Agreement in the same manner and to the same extent that the
Employers would be required to perform it if no such succession had taken place.
Failure by either of the Employers to obtain such assumption and agreement prior
to the effectiveness of any such succession shall constitute a breach of this
Agreement and the provisions of Section 3 hereof shall apply. As used in this
Agreement, the term "Employers" shall mean any successor to the respective
business and/or assets of the


                                        8

Employers or either of them that assumes, by operation of law or otherwise, the
Employers' obligations under this Agreement.

     17. Enforceability. If any portion or provision of this Agreement shall to
any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law. The agreements of the Executive contained in
Section 11 and Section 12 hereof are of a special, unique and extraordinary
character, and the obligations of the Executive set forth therein shall
therefore be enforceable both at law and in equity, by injunction or otherwise.
The rights and remedies of the parties hereunder shall be cumulative and not
alternative and shall not be exhausted by any one or more uses thereof

     18. Waiver. No waiver of any provision hereof shall be effective unless
made in writing and signed by the waiving party. Only the Chief Executive
Officer of the Company or the Bank, as applicable, is authorized by such entity
to sign a writing waiving a provision hereof. The failure of any party to
require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

     19. Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, to the
Executive at the last address the Executive has filed in writing with the
Employers or, in the case of the Bank, at its main offices, attention of the
Clerk or, in the case of the Company, at its main office, attention of the
Secretary.

     20. Election of Remedies. An election by the Executive to resign for Good
Reason after a Change in Control under the provisions of this Agreement shall
not constitute a breach by the Executive of any employment agreement between the
Employers and the Executive and shall be deemed a voluntary termination of
employment by the Executive for the purpose of interpreting the provisions of
any of the Employers' benefit plans, programs or policies.

     21. Time. Time is of the essence with respect to the performance of every
provision of this Agreement.

     22. Entire Agreement. This Agreement represents the entire and integrated
agreement among the Employers and the Executive regarding the subject matter
hereof and supersedes all prior negotiations, representations or agreements,
either written or oral. Notwithstanding the immediately preceding sentence,
except as expressly provided in this Agreement, nothing in this Agreement shall
affect in any way any benefit to which the Executive may be entitled under any
prior written agreement or previously adopted plan.

     23. Construction. Headings at the beginning of each paragraph are solely
for the convenience of the parties and are not a part of this Agreement.
Whenever required by the context of this Agreement, the singular shall include
the plural and the masculine shall include the feminine and vice versa. This
Agreement shall not be construed as if it had been prepared by


                                        9

one of the parties, but rather as if both parties had prepared the same. Unless
otherwise indicated, all references to sections are to this Agreement.

     24. Amendment. This Agreement may be amended or modified only by a written
instrument signed by the Executive and by duly authorized representatives of
each of the Employers.

     25. Allocation of Obligations Between Employers. The obligations of the
Employers under this Agreement are intended to be the joint and several
obligations of the Bank and the Company and the Employers shall, as between
themselves, allocate these obligations in a manner agreed upon by them.
Notwithstanding any other provision of this Agreement, neither the Company nor
the Bank shall have any obligation to pay the Severance Payment or to provide
any other benefit hereunder if and to the extent such Severance Payment or other
benefit is prohibited by applicable federal or state law, including without
limitation Part 359 of the regulations of the Federal Deposit Insurance
Corporation (12 CFR Section 359 et seq.) or any successor provision.

     26. Governing Law. This is a Massachusetts contract and shall be construed
under and be governed in all respects by the laws of the Commonwealth of
Massachusetts.
