                                 FOR DIRECTORS

Section 1. Purpose

      1.1 The purpose of the Rockville Bank Non-Qualified Deferred Compensation

      2.4 "Deferral" shall mean the amount credited to a Participant's Deferral
Account for a Plan Year to reflect Compensation otherwise payable to a
Participant during such Plan Year which such Participant has elected to defer
pursuant to Section 4 hereof.

Participant on the books of the Bank to reflect Deferrals, adjusted for earnings
and losses thereon.

      2.6 "Effective Date" shall mean December 12, 2001.

of the Board (the "Committee"). The Committee shall have full power and
authority to construe and interpret the Plan, establish and amend administrative

necessary to administer the Plan. The Committee's decisions, actions, and
interpretations regarding the Plan shall be final and binding upon all
Participants and Beneficiaries.

      3.2 The Committee shall act by vote or written consent of a majority of
its members. Members of the Committee who are either eligible to become

affecting the administration of the Plan, provided, however, that no member of
the Committee may vote on or participate in any matter directly relating to the
benefits of such member.

      3.3 The Committee, or its designee, shall (a) notify Directors about

and earnings and losses thereon, payment of Deferral Account balances, and
Beneficiary designations; (d) prepare communications to Participants and
Beneficiaries; (e) prepare reports and data required by the Bank concerning the
Plan; (f) obtain necessary consents and approvals; and (g) take any other
actions as are otherwise necessary or appropriate for effective implementation
and administration of the Plan.

Section 4. Deferrals

      4.1 Each Director may become a Participant for a Plan Year (or, during the
first year of service on the Board, the portion thereof after electing to
participate) by electing to make Deferrals for such Plan Year prior to the
commencement of the Plan Year. During a Director's first year of service, or
during the initial year of the Plan's operation, such Deferral Election shall be
made within thirty (30) days after election to the Board or within thirty (30)
days after the later of the Plan's adoption or its Effective Date, as
applicable. All elections to make Deferrals shall be made on such forms as shall
be provided to the Participant by the Committee. Any deferral election will be
effective only with respect to Compensation received for services performed
after the election is effective.

      4.2 A Participant may elect to defer 0%, 25%, 50%, 75% or 100% of
Compensation for any Plan Year. Each election of Deferral shall be effective
only with respect to the Plan Year to which such election of Deferral applies.
Elections to make Deferrals for a Plan Year and the amount of such Deferrals for
such Plan Year shall be irrevocable.

      4.3 A Participant's Deferrals shall be credited to a Participant's
Deferral Account in accordance with procedures determined by the Committee. A
Participant shall at all times be fully vested in his Deferral Account.

      4.4 Notwithstanding anything to the contrary set forth herein, Deferrals
(and the earnings and losses accrued thereon) shall remain the general assets of
the Bank until distributed in accordance with Section 6, below.

                                      -2-
<PAGE>

Section 5. Growth of Deferral Accounts

      5.1 A Participant's Deferral Account shall be invested, at the election of
the Participant, in one or more of the investment funds or options made
available by the Bank under the terms of the Plan from time to time. Investment
elections shall be subject to nondiscriminatory rules and procedures approved by
the Committee in its discretion from time to time, including rules with respect
to timing and frequency of investment changes. A Participant's Deferral Account
shall be increased by the amount of income and gains and reduced by the amount
of losses realized by investing in the investment funds elected by the
Participant. Expenses incurred in connection with any such investment funds
shall be deducted from the Participant's Deferral Accounts. Notwithstanding
anything to the contrary set forth herein, in no event shall the Bank or the
Committee be responsible for, and shall not be held liable for, the investment
performance of any investment made available hereunder.

      5.2 Notwithstanding anything to the contrary set forth herein, the amounts
so invested shall remain the general assets of the Bank until distributed in
accordance with Section 6, below.

Section 6. Distribution

      A Participant shall elect in writing, and file with the Committee, at the
same time as the initial Deferral election, a method of payment of his or her
Deferral Account from the following methods:

            (a)   Payment of amounts credited to the Participant's Deferral
                  Account in a single lump sum as of the January 1 of the year
                  next following the Participant's Termination of Service; or

            (b)   Payment of amounts credited to the Participant's Deferral
                  Account in a specified number of consecutive annual
                  installments, not to exceed five (5), the first installment to
                  be paid as of the January 1 next following the Participant's
                  Termination of Service; or

            (c)   Payment of amounts credited to the Participant's Deferral
                  Account over a specified period, not to exceed five (5) years,
                  in biweekly installments, the first installment to be paid as
                  of the January 1 next following the Participant's Termination
                  of Service; or

            (d)   Payment of amounts credited to the Participant's Deferral
                  Account in a single lump sum as of January 1 of the year
                  specified by the Participant; or

            (e)   Payment of amounts credited to the Participant's Deferral
                  Account in a specified number of consecutive annual
                  installments, not to exceed five (5), the first installment to
                  be paid as of January 1 of the year specified by the
                  Participant.

            (f)   Payment of amounts credited to the Participant's Deferral
                  Account over a specified period, not to exceed five (5) years,
                  in biweekly installments, the

                                      -3-
<PAGE>

                  first installment to be paid as of the January 1 of the year
                  specified by the Participant.

A Participant may change an election as to the form of payment and/or the date
of distribution by filing a subsequent written election, provided, however, that
(i) no such change shall be given effect if made within twelve (12) months prior
to the previously elected distribution date or the Participant's Termination of
Service for any reason, and (ii) the new distribution date cannot be less than
twelve (12) months from the date the new election form is filed with the
Committee.

Section 7. Distribution Upon Death

      7.1 The Committee shall distribute the Participant's Deferral Account
balance to the Participant's estate in a single lump sum as soon as
administratively feasible after the Participant's death.

Section 8. General Provisions

      8.1 The rights of a Participant to the payment of deferred compensation as
provided in the Plan shall not be assigned, pledged, or encumbered or be subject
in any manner to alienation or anticipation. No Participant may borrow against
his or her Deferral Account balance. Deferral Accounts shall not be subject in
any manner to anticipation, alienation, sale, transfer, assignment, pledge,
encumbrance, charge, garnishment, execution or levy of any kind, whether
voluntary or involuntary, including, but not limited to, any liability which is
for alimony or other payments for the support of a spouse or former spouse, or
for any other relative of any Participant. Any such attempted assignment or
transfer shall be void.

      8.2 The Plan is intended to constitute an unfunded deferred compensation
arrangement. Nothing contained in the Plan, and no action taken pursuant to the
Plan, shall create or be construed to create a trust of any kind. The Bank's
obligations hereunder shall be an unfunded and unsecured promise to pay money in
the future for tax purposes and, if applicable, for purposes of Title I of
ERISA. A Participant's right to receive his or her Deferral Account balance
shall be no greater than the right of an unsecured general creditor of the Bank.
Deferral Account balances shall be paid from the general funds of the Bank, and
no special or separate fund shall be established and no segregation of assets
shall be made to assure payment of such Deferral Account balances.
Notwithstanding the foregoing, the Bank may, in its discretion and in
conjunction with maintaining this Plan, establish a so-called "rabbi trust." Any
such trust created by the Bank, and any assets held thereunder to assist the
Bank in meeting its obligations under this Plan, shall conform to the terms of
the model trust as described in Revenue Procedure 92-64.

      8.3 Nothing contained in the Plan shall give any Participant the right to
continue as a Director of the Bank.

      8.4 The Plan shall be construed and governed in accordance with the laws
of the State of Connecticut, to the extent not preempted by federal law.

                                      -4-
<PAGE>

Section 9. Withholding

      9.1 The Bank shall deduct from all amounts paid under this Plan any taxes
required to be withheld by any federal, state, or local government tax statutes.
The Participants and their Beneficiaries, distributees, and personal
representatives will be responsible for the payment of any and all federal,
foreign, state, local, or other income or other taxes imposed on amounts paid
under this Plan.

Section 10. Amendment, Suspension, or Termination

      10.1 The Bank, by action of its Board of Directors, reserves the right to
amend, suspend, or terminate the Plan at any time and for any reason; provided,
however, that, except as provided in this Section 10.1, any amendment,
suspension, or termination shall not adversely affect the rights of the
Participants or Beneficiaries to receive Deferrals and earnings thereon credited
to their Deferral Accounts prior to such action. In the event the Plan is
terminated, Deferral Account balances shall be distributed to Participants and
Beneficiaries, in a lump sum, as soon as practicable thereafter.

      IN WITNESS WHEREOF, the undersigned has executed this Plan this 12th day
of December, 2001.

                              ____________ 100%

                  I understand that the Bank shall retain the amount I elect to
                  defer in accordance with the terms of the Rockville Bank
                  Non-Qualified Deferred Compensation Plan for Directors (the
                  "Plan") and that such amounts may not be distributed to me
                  except in accordance with the terms of the Plan.

            2.    I understand that the foregoing election is irrevocable for
                  the Calendar Year indicated above, unless revoked by me in
                  writing prior to the beginning of such year. I understand that
                  if I wish to make deferrals in a subsequent year, I must
                  complete a new Deferral Agreement prior to the beginning of
                  that year.

            3.    I hereby acknowledge that I have received a copy of the Plan
                  document and that I have been given a Plan Distribution
                  Election Form.
