Executive's performance hereunder) an extension of the term of this Agreement,
and the term shall continue to extend each year if the Board of Directors
approves such extension unless the Executive gives written notice to the
Employers of the Executive's election not to extend the term, with such written
notice to be given not less than thirty (30) days prior to any such anniversary
date. If the Board of Directors elects not to extend the term, it shall give
written notice of such decision to the Executive not less than thirty (30) days
prior to any such anniversary date. If any party gives timely notice that the
term will not be extended as of any annual anniversary date, then this Agreement
shall terminate at the conclusion of its remaining term. References herein to
the term of this Agreement shall refer both to the initial term and successive
terms.

     (b)  During the term of this Agreement, the Executive shall perform such
executive services for the Corporation as may be consistent with her titles and
from time to time assigned to her by the Corporation's Board of Directors.

     3.   Compensation and Benefits.

     (a)  The Employers shall compensate and pay the Executive for her
services during the term of this Agreement at a minimum base salary of $327,200
per year ("Base Salary"), which may be increased from time to time in such
amounts as may be determined by the Boards of Directors of the Employers and may
not be decreased without the Executive's express written consent. In addition to
her Base Salary, the Executive shall be entitled to receive during the term of
this Agreement such bonus payments as may be determined by the Boards of
Directors of the Employers.

     (b)  During the term of this Agreement, the Executive shall be entitled
to participate in and receive the benefits of any pension or other retirement
benefit plan, profit sharing, stock option, employee stock ownership, or other
plans, benefits and privileges given to employees and executives of the
Employers, to the extent commensurate with her then duties and responsibilities,
as fixed by the Boards of Directors of the Employers. The Corporation shall not
make any changes in such plans, benefits or privileges which would adversely
affect the Executive's rights or benefits thereunder, unless such change occurs
pursuant to a program applicable to all executive officers of the Corporation
and does not result in a proportionately greater adverse change in the rights of
or benefits to the Executive as compared with any other executive officer of the
Corporation. Nothing paid to the Executive under any plan or arrangement
presently in effect or made available in the future shall be deemed to be in
lieu of the salary payable to the Executive pursuant to Section 3(a) hereof.

     (c)  During the term of this Agreement, the Executive shall be entitled
to paid annual vacation in accordance with the policies as established from time
to time by the Boards of Directors of the Employers, which shall in no event be
less than five weeks per annum. The Executive shall not be entitled to receive
any additional compensation from the Employers for failure to take a vacation,
nor shall the Executive be able to accumulate unused vacation time from one year
to the next, except to the extent authorized by the Boards of Directors of the
Employers.

                                        4

     (d)  During the term of this Agreement, in keeping with past practices,
the Employers shall continue to provide the Executive with the automobile she
presently drives. The Employers shall be responsible and shall pay for all costs
of insurance coverage, repairs, maintenance and other incidental expenses,
including license, fuel and oil.

     (e)  In the event the Executive's employment is terminated by the
Corporation for any reason other than Cause, the Employers shall provide
continued life, medical, dental and disability coverage substantially identical
to the coverage maintained by the Employers for the Executive immediately prior
to her termination. The medical and dental coverage shall continue until the
earlier of (a) the Executive's death or (b) the date on which the Executive is
entitled to receive benefits from a subsequent employer which are substantially
similar to the medical and dental coverage provided by the Corporation. The life
and disability coverage shall cease upon the expiration of the remaining term of
this Agreement. During the period that the Executive receives medical and dental
coverage and/or life and disability coverage, the Executive shall pay the
employee share of the costs of such coverages as if she was still an employee.

     (f)  In the event of the Executive's death during the term of this
Agreement, her spouse, estate, legal representative or named beneficiaries (as
directed by the Executive in writing) shall be paid on a monthly basis the
Executive's annual compensation from the Employers at the rate in effect at the
time of the Executive's death for the remainder of the term of this Agreement,
as well as the benefits specified in Section 3(e) hereof. In the event the
Executive is terminated due to Disability during the term of this Agreement, the
Executive shall be paid on a monthly basis (i) the Executive's annual
compensation from the Employers at the rate in effect at the time of termination
due to Disability for the remainder of the term of this Agreement, as well as
the benefits specified in Section 3(e) hereof, and (ii) upon the expiration of
the term of this Agreement, two-thirds (66.67%) of the Executive's Base Salary
at the time of termination due to Disability until the Executive reaches the
normal retirement age of 65; provided however, there shall be deducted from the
amounts paid the Executive pursuant to this Section 3(f), any amounts actually
paid to the Executive pursuant to any disability insurance or similar plan or
program which the Employers have instituted or may institute on behalf of the
Executive or its employees for the purpose of compensating employees in the
event of disability, the Social Security Act, the Workers Compensation or
Occupational Disease Act or any state disability benefit law.

     (g)  The Executive's compensation, benefits and expenses shall be paid
by the Corporation and the Bank in the same proportion as the time and services
actually expended by the Executive on behalf of each respective Employer.

     4.   Expenses. The Employers shall reimburse the Executive or otherwise
provide for or pay for all reasonable expenses incurred by the Executive in
furtherance of or in connection with the business of the Employers, including,
but not by way of limitation, automobile expenses described in Section 3(d)
hereof, and traveling expenses, and all reasonable entertainment expenses
(whether incurred at the Executive's residence, while traveling or otherwise),
subject to such reasonable documentation and other limitations as may be
established by the Boards of Directors of the Employers. If such expenses are
paid in the first instance by the Executive, the Employers shall reimburse the
Executive therefor.

     5.   Termination.

     (a)  The Corporation shall have the right, at any time upon prior Notice
of Termination, to terminate the Executive's employment hereunder for any
reason, including without limitation termination for Cause, Disability or
Retirement, and the Executive shall have the right, upon prior Notice of
Termination, to terminate her employment hereunder for any reason.

     (b)  In the event that (i) the Executive's employment is terminated by
the Corporation for Cause or (ii) the Executive terminates her employment
hereunder other than for Disability, Retirement, death or Good Reason, the
Executive shall have no right pursuant to this Agreement to compensation or
other benefits for any period after the applicable Date of Termination.

     (c)  In the event that the Executive's employment is terminated as a
result of Disability, Retirement or the Executive's death during the term of
this Agreement, the Executive shall have no right pursuant to this Agreement to
compensation or other benefits for any period after the applicable Date of
Termination, except as provided for in Sections 3(e) and 3(f) hereof.

     (d)  In the event that (i) the Executive's employment is terminated by
the Corporation for other than Cause, Disability, Retirement or the Executive's
death or (ii) such employment is terminated by the Executive (a) due to a
material breach of this Agreement by the Corporation, which breach has not been
cured within fifteen (15) days after a written notice of non-compliance has been
given by the Executive to the Employers, or (b) for Good Reason, then the
Corporation shall

     (A)  pay to the Executive, in either thirty-six (36) equal monthly
installments beginning with the first business day of the month following the
Date of Termination or in a lump sum within five business days of the Date of
Termination (at the Executive's election), a cash severance amount equal to
three (3) times that portion of the Executive's Average Annual Compensation paid
by the Corporation,

     (B)  maintain and provide for a period ending at the earlier of (i) )
thirty-six (36) months after the Date of Termination or (ii) the date of the
Executive's full-time employment by another employer (provided that the
Executive is entitled under the terms of such employment to benefits
substantially similar to those described in this subparagraph (B)), at no cost
to the Executive, the Executive's continued participation in all group
insurance, life insurance, health and accident, disability and other employee
benefit plans, programs and arrangements offered by the Corporation in which the
Executive was entitled to participate immediately prior to the Date of
Termination (other than stock option and restricted stock plans of the
Employers),

     (C)  if the Executive is still receiving medical and dental coverage
pursuant to Section 5(d)(B) above upon the expiration of thirty-six (36) months
after the Date of Termination, maintain and provide medical and dental coverage
for the Executive for a period ending at the

                                        6

<PAGE>

earlier of (i) the Executive's death or (ii) the date on which the Executive is
entitled to receive benefits from a subsequent employer which are substantially
similar to the medical and dental coverage provided by the Corporation. During
the period that the Executive receives medical and dental coverage pursuant to
this Section 5(d)(C), the Executive shall pay the employee share of the costs of
such coverage as if she was still an employee, and

     (D)  in the event that the Executive's participation in any plan, program
or arrangement as provided in subparagraph (B) or (C) of this Section 5(d) is
barred, or during such period any such plan, program or arrangement is
discontinued or the benefits thereunder are materially reduced, the Corporation
shall arrange to provide the Executive with benefits substantially similar to
those which the Executive was entitled to receive under such plans, programs and
arrangements immediately prior to the Date of Termination.

     6.   Payment of Additional Benefits under Certain Circumstances.

     (a)  If the payments and benefits pursuant to Section 5 hereof, either
alone or together with other payments and benefits which the Executive has the
right to receive from the Employers (including, without limitation, the payments
and benefits which the Executive would have the right to receive from the Bank
pursuant to Section 5 of the Agreement between the Bank and the Executive dated
as of the date hereof ("Bank Agreement"), before giving effect to any reduction
in such amounts pursuant to Section 6 of the Bank Agreement), would constitute a
"parachute payment" as defined in Section 280G(b)(2) of the Code (the "Initial
Parachute Payment," which includes the amounts paid pursuant to clause (A)
below), then the Corporation shall pay to the Executive, in thirty-six (36)
equal monthly installments beginning with the first business day of the month
following the Date of Termination or in a lump sum within five business days of
the Date of Termination (at the Executive's election), a cash amount equal to
the sum of the following:

     (A)  the amount by which the payments and benefits that would have
otherwise been paid by the Bank to the Executive pursuant to Section 5 of the
Bank Agreement are reduced by the provisions of Section 6 of the Bank Agreement;

     (B)  twenty (20) percent (or such other percentage equal to the tax rate
imposed by Section 4999 of the Code) of the amount by which the Initial
Parachute Payment exceeds the Executive's "base amount" from the Employers, as
defined in Section 280G(b)(3) of the Code, with the difference between the
Initial Parachute Payment and the Executive's base amount being hereinafter
referred to as the "Initial Excess Parachute Payment";

     (C)  such additional amount (tax allowance) as may be necessary to
compensate the Executive for the payment by the Executive of state and federal
income and excise taxes on the payment provided under clause (B) above and on
any payments under this clause (C). In computing such tax allowance, the payment
to be made under clause (B) above shall be multiplied by the "gross up
percentage" ("GUP"). The GUP shall be determined as follows:

                                        7

<PAGE>

                                            GUP =    Tax Rate
                                                     ----------
                                                     1-Tax Rate

The Tax Rate for purposes of computing the GUP shall be the highest marginal
federal and state income and employment-related tax rate, including any
applicable excise tax rate, applicable to the Executive in the year in which the
payment under clause (B) above is made.

     (b)  Notwithstanding the foregoing, if it shall subsequently be determined
in a final judicial determination or a final administrative settlement to which
the Executive is a party that the actual excess parachute payment as defined in
Section 280G(b)(1) of the Code is different from the Initial Excess Parachute
Payment (such different amount being hereafter referred to as the "Determinative
Excess Parachute Payment"), then the Corporation's independent tax counsel or
accountants shall determine the amount (the "Adjustment Amount") which either
the Executive must pay to the Corporation or the Corporation must pay to the
Executive in order to put the Executive (or the Corporation, as the case may be)
in the same position the Executive (or the Corporation, as the case may be)
would have been if the Initial Excess Parachute Payment had been equal to the
Determinative Excess Parachute Payment. In determining the Adjustment Amount,
the independent tax counsel or accountants shall take into account any and all
taxes (including any penalties and interest) paid by or for the Executive or
refunded to the Executive or for the Executive's benefit. As soon as practicable
after the Adjustment Amount has been so determined, the Corporation shall pay
the Adjustment Amount to the Executive or the Executive shall repay the
Adjustment Amount to the Corporation, as the case may be.

     (c)  In each calendar year that the Executive receives payments of benefits
under this Section 6, the Executive shall report on her state and federal income
tax returns such information as is consistent with the determination made by the
independent tax counsel or accountants of the Corporation as described above.
The Corporation shall indemnify and hold the Executive harmless from any and all
losses, costs and expenses (including without limitation, reasonable attorneys'
fees, interest, fines and penalties) which the Executive incurs as a result of
so reporting such information. The Executive shall promptly notify the
Corporation in writing whenever the Executive receives notice of the institution
of a judicial or administrative proceeding, formal or informal, in which the
federal tax treatment under Section 4999 of the Code of any amount paid or
payable under this Section 6 is being reviewed or is in dispute. The Corporation
shall assume control at its expense over all legal and accounting matters
pertaining to such federal tax treatment (except to the extent necessary or
appropriate for the Executive to resolve any such proceeding with respect to any
matter unrelated to amounts paid or payable pursuant to this Section 6) and the
Executive shall cooperate fully with the Corporation in any such proceeding. The
Executive shall not enter into any compromise or settlement or otherwise
prejudice any rights the Corporation may have in connection therewith without
the prior consent of the Corporation.

     7.   Mitigation; Exclusivity of Benefits.

     (a)  The Executive shall not be required to mitigate the amount of any
benefits hereunder by seeking other employment or otherwise, nor shall the
amount of any such benefits be reduced by any compensation earned by the
Executive as a result of employment by another employer after the Date of
Termination or otherwise.

     (b)  The specific arrangements referred to herein are not intended to
exclude any other benefits which may be available to the Executive upon a
termination of employment with the Employers pursuant to employee benefit plans
of the Employers or otherwise.

     8.   Withholding. All payments required to be made by the Corporation
hereunder to the Executive shall be subject to the withholding of such amounts,
if any, relating to tax and other payroll deductions as the Corporation may
reasonably determine should be withheld pursuant to any applicable law or
regulation.

     9.   Assignability. The Corporation may assign this Agreement and its
rights and obligations hereunder in whole, but not in part, to any corporation,
bank or other entity with or into which the Corporation may hereafter merge or
consolidate or to which the Corporation may transfer all or substantially all of
its assets, if in any such case said corporation, bank or other entity shall by
operation of law or expressly in writing assume all obligations of the
Corporation hereunder as fully as if it had been originally made a party hereto,
but may not otherwise assign this Agreement or its rights and obligations
hereunder. The Executive may not assign or transfer this Agreement or any rights
or obligations hereunder.

     10.  Notice. For the purposes of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be

     11.  Amendment; Waiver. No provisions of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by the Executive and such officer or officers as may be
specifically designated by the Board of Directors of the Corporation to sign on
its behalf. No waiver by any party hereto at any time of any breach by any other
party hereto of, or compliance with, any condition or provision of this

similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time.

performance of this Agreement shall be governed by the laws of the United States
where applicable and otherwise by the substantive laws of the Commonwealth of

     13.  Nature of Obligations. Nothing contained herein shall create or
require the Corporation to create a trust of any kind to fund any benefits which
may be payable hereunder, and to the extent that the Executive acquires a right
to receive benefits from the Corporation hereunder, such right shall be no
greater than the right of any unsecured general creditor of the Corporation.

reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

     15.  Validity. The invalidity or unenforceability of any provision of this

provisions of this Agreement, which shall remain in full force and effect.

     16.  Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

     17.  Entire Agreement. This Agreement embodies the entire agreement between
the Corporation and the Executive with respect to the matters agreed to herein.
All prior agreements between the Corporation and the Executive with respect to
the matters agreed to herein, including without limitation the Agreement between
the Employers and the Executive dated June 13, 1990 and the Agreements between
the Corporation and the Executive dated November 16, 1999, December 1, 2000 and
December 1, 2001, are hereby superseded and shall have no force or effect.
Notwithstanding the foregoing, nothing contained in this Agreement shall affect
the agreement of even date being entered into between the Bank and the
Executive.
