"Agent") with respect to the offer and sale by the Company of up to
_____________ shares of its common stock, par value $2.00 per share (the "Common

          The Company is offering _____________ shares of Common Stock to the

holders described below, to certain other purchasers on a standby basis. Each
Record Date Holder will receive one (1) non-transferable subscription right

close of business on the Record Date. Each Right will enable the holder thereof
to purchase from the Company one share of Common Stock (an "Underlying Share")
at the Subscription Price (the "Basic Subscription Privilege"). Each Record Date
Holder who fully exercises their Basic Subscription Privilege also will be
eligible to subscribe at the Subscription Price for shares of Common Stock (the
"Excess Shares") not otherwise purchased pursuant to the exercise of the Basic
Subscription Privilege up to the total number of Underlying Shares, subject to
availability, proration, and reduction by the Company in certain circumstances

subject in each case to a maximum standby commitment and certain conditions, to
acquire from the Company at the Subscription Price up to an aggregate of
____________ of the Underlying Shares remaining upon completion of the Rights
Offering. The Standby Purchase Agreements will require that the Standby
Purchasers agree to purchase and the Company agrees to sell, and thus guarantee
the availability of, an aggregate minimum of __________ shares of Common Stock
("Additional Shares") at the

after the exercise of the Basic Subscription Privilege and the Oversubscription
Privilege to satisfy the purchase commitments of the Standby Purchasers, subject
to reduction to a minimum of ___________ shares to the extent Record Date
Holders subscribe for all of the Rights granted to them (the "Minimum Standby
Obligation"). The Rights Offering and the offering to Standby Purchasers are
together referred to herein as the "Offering," and the Underlying Shares and the
Additional Shares are together referred to herein as the "Securities."

          Record Date Holders may exercise subscription rights by delivering to
the subscription agent a properly completed and executed subscription rights
certificate together with payment in full of the subscription price for each
share subscribed for. Payment may be made only (i) by check or bank draft drawn
upon a U.S. bank, or postal, telegraphic or express money order payable to
Registrar and Transfer Company ("R&T") as subscription agent, or (ii) by wire
transfer of funds to R&T for the purpose of accepting subscriptions in
connection with the transactions contemplated hereby.

1933, as amended (the "1933 Act"), has filed such amendments thereto, if any,
and such amended prospectuses as may have been required to the date hereof by

Statement" and the "Prospectus," respectively, except that if any revised
prospectus shall be used by the Company in connection with the Offering which
differs from the Prospectus on file with the Commission at the time the
Registration Statement becomes effective (whether or not such revised prospectus
is required to be filed by the Company pursuant to Rule 424(b) of the 1933 Act
Regulations), the term "Prospectus" shall refer to such revised prospectus from

Material Adverse Effect. Except as described in the Registration Statement and
the Prospectus, neither the Company nor any of the subsidiaries has been named

an earlier date, (v) the Company and the Bank have complied with all agreements
and satisfied all conditions on their part to be performed or satisfied at or
prior to Closing Time, (vi) no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose have
been initiated or threatened by the Commission, and (vii) no order, directive,
request or other correspondence has been received by the Company or any of its
subsidiaries from the FRB, the OCC or the FDIC which could have the effect of
delaying or canceling the Offering.

                 (ii) At the Closing Time, the Agent shall have received a
certificate of each of the Chief Executive Officer and the President of each of
the Company and the Bank and the Chief Financial Officer of the Company and the
Bank dated as of Closing Time, to the effect that (i) they have reviewed the
contents of the Registration Statement and the Prospectus; (ii) based on each of
their knowledge, the Registration Statement and the Prospectus do not contain
any untrue statement of a material fact or omit to state a material

                                       17
<Page>

fact necessary in order to make the statements made therein, in light of the
circumstances under which such statements were made, not misleading; (iii) based
on each of their knowledge, the financial statements and other financial
information included in the Registration Statement and the Prospectus fairly
present in all material respects the financial condition and results of
operations of the Company and its subsidiaries as of and for the dates and
periods presented in the Registration Statement and the Prospectus; (iv) they
are responsible for establishing and maintaining disclosure controls and

caused such disclosure controls and procedures to be designed under their
supervision, to ensure that material financial information relating to the

disclosed to McGladrey & Pullen, LLP and the Audit Committee of the Company (A)
all significant deficiencies and material weaknesses in the design or operation
of internal control over financial reporting which are reasonably likely to
adversely affect the Company's and the Bank's ability to record, process,
summarize, and report financial data, and (B) any fraud, whether or not
material, that involves management or other employees who have a significant
role in the Company's and the Bank's internal control over financial reporting,
and any such deficiencies or fraud have either been disclosed in the
Registration Statement and the Prospectus or are not material to the Company and
its subsidiaries taken as a whole.

               (e)    At the time of the execution of this Agreement, the Agent
shall have received from McGladrey & Pullen, LLP, a letter dated such date, in
form and substance satisfactory to the Agent, to the effect that (i) they are
independent certified public accountants with respect to the Company and its
subsidiaries within the meaning of the Code of Ethics of the AICPA, the 1933 Act
and the 1933 Act Regulations; (ii) it is their opinion that the consolidated
financial statements and supporting schedules included in the Registration
Statement and covered by their opinion therein comply as to form in all material
respects with the applicable accounting requirements of the 1933 Act and the
1933 Act Regulations; (iii) based upon limited procedures as agreed upon by the
Agent and McGladrey & Pullen, LLP, and set forth in detail in such letter,
nothing has come to their attention which causes them to believe that (A) the
unaudited financial statements and supporting schedules of the Company included
in the Registration Statement do not comply as to form in all material respects
with the applicable accounting requirements of the 1933 Act and the 1933 Act
Regulations or are not presented in conformity with GAAP applied on a basis
substantially consistent with that of the audited financial statements included
in the Registration Statement and the Prospectus, (B) at a specified date not
more than five days prior to the date of this Agreement, there has been any
increase in the consolidated available for sale investment securities or total
borrowings of the Company or any decrease in consolidated total assets,
allowance for loan losses, total deposits or shareholders' equity of the
Company, in each case as compared with the amounts shown in the December 31,
2004 balance sheet included in the Registration Statement or, (C) during the
period from December 31, 2004 to a specified date not more than five days prior
to the date of this Agreement, there were any decreases, as compared with the
corresponding period in the preceding year, in total interest income, net
interest income, net interest income after provision for loan losses, income
before income tax expense or net income of the Company, except in all instances,
for increases or decreases which the Registration Statement and the Prospectus
disclose have occurred or may occur; and (iv) in addition to the examination
referred to in their opinions and the limited procedures referred to in clause
(iii) above, they have carried out certain specified procedures, not
constituting an audit, with respect to certain amounts, percentages

                                       18
<Page>

and financial information which are included in the Registration Statement and
Prospectus and which are specified by the Agent, and have found such amounts,
percentages and financial information to be in agreement with the relevant
accounting, financial and other records of the Company and its subsidiaries
identified in such letter.

               (f)    At the Closing Time, the Agent shall have received from
McGladrey & Pullen, LLP a letter, dated as of Closing Time, to the effect that
they reaffirm the statements made in the letter furnished pursuant to subsection
(e) of this Section, except that the specified date referred to shall be a date
not more than five days prior to Closing Time.

               (g)    At the Closing Time, counsel for the Agent shall have been
furnished with such documents and opinions as they may require for the purpose
of enabling them to pass upon the issuance and sale of the Securities as herein
contemplated and related proceedings, or in order to evidence the accuracy of
any of the representations or warranties, or the fulfillment of any of the
conditions, herein contained; and all proceedings taken by the Company in
connection with the issuance and sale of the Securities as herein contemplated
shall be satisfactory in form and substance to the Agent and counsel for the
Agent.

               (h)    The Agent shall have received Lock-up Agreements, dated as
of the Closing Date, from all of the Company's executive officers and directors,
in the form and to the effect contemplated in Section 1(xxxviii).

               (i)    At any time prior to Closing Time, (i) there shall not
have occurred any material adverse change in the financial markets in the United
States or elsewhere or any outbreak of hostilities or escalation thereof or
other calamity or crisis the effects of which, in the judgment of the Agent, are
so material and adverse as to make it impracticable to market the Securities or
to enforce contracts, including subscriptions or orders, for the sale of the
Securities, and (ii) trading generally on either the New York Stock Exchange or
NASDAQ shall not have been suspended, and minimum or maximum prices for trading
shall not have been fixed, or maximum ranges for prices for securities have been
required, by either the New York Stock Exchange, the NASD or by order of the
Commission or any other governmental authority, and a banking moratorium shall
not have been declared by Federal, New York or Connecticut authorities.

               (j)    If any condition specified in this Section shall not have
been fulfilled when and as required to be fulfilled, this Agreement may be
terminated by the Agent by notice to the Company and the Bank at any time at or
prior to the Closing Time, and such termination shall be without liability of
any party to any other party except as provided in Section 4 hereof and except
that Section 6 and 7 hereof shall survive any such termination and remain in
full force and effect.

SECTION 6.     INDEMNIFICATION.

               (a)    INDEMNIFICATION OF AGENT. The Company and the Bank agree
to jointly and severally indemnify and hold harmless: (x) the Agent; (y) each
person, if any, who controls (within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act) the Agent (each such person, a "controlling
person"); and (z) the respective partners, directors, officers, employees and
agents of the Agent or any such controlling person as follows:

                      (i)       against any and all loss, liability, claim,
damages and expense whatsoever, as incurred, relating to or arising out of, or
based upon, in whole or in part, (A)

                                       19
<Page>

any action taken by the Agent where acting as agent of the Company and the Bank
or as otherwise described in Section 2 hereof, (B) any untrue statement or
alleged untrue statement of a material fact included in the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or the
omission or alleged omission therefrom of a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; (C) any untrue statement or alleged untrue statement
of material fact contained in any information or documents executed in favor of
or furnished or made available to the Agent by the Company and the Bank; (D) any
omission or alleged omission to state in any information or documents executed
in favor of or furnished or made available to the Agent by the Company and the
Bank a material fact necessary to make the statements therein not misleading; or
(E) the breach or alleged breach of any representation, warranty and agreement
of the Company and the Bank contained herein;

                      (ii)      against any and all loss, liability, claim,
damage and expense whatsoever, as incurred, to the extent of the aggregate
amount paid in settlement of any litigation, or any investigation or proceeding
by any governmental agency or body, commenced or threatened, or of any claim
whatsoever based upon any such untrue statement or omission, or any such alleged
untrue statement or omission, or breach or alleged breach of any such
representation, warranty or agreement; provided that (subject to Section 6(d)
hereof) any such settlement is effected with the written consent of the Company
and the Bank; and

                      (iii)     against any and all expense whatsoever, as
incurred (including the fees and disbursements of counsel chosen by the Agent),
reasonably incurred in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue statement or omission, or any such alleged untrue statement or omission,
or breach or alleged breach of any such representation, warranty or agreement,
to the extent that any such expense is not paid under (1) or (2) above;

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with the Agent's Information.

          Notwithstanding the foregoing, the indemnification provided for in
this paragraph (a) shall not apply to the Bank to the extent that such
indemnification by the Bank is found in a final, non-appealable judgment by a
court of competent jurisdiction to constitute a violation of any financial
institution law or regulation applicable to national banks and the Bank,
including if such indemnification is so found to constitute a covered
transaction under 23A of the Federal Reserve Act.

               (b)    INDEMNIFICATION OF OFFERORS, DIRECTORS, OFFICERS AND
EMPLOYEES. The Agent agrees to indemnify and hold harmless the Company and the
Bank, their directors, officers and employees, and each person, if any, who
controls the Company, or the Bank within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act against any and all loss, liability, claim,
damage and expense described in the indemnity contained in Section 6(a) above,
as incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in conformity with the Agent's Information.

               (c)    ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified
party shall give notice as promptly as reasonably practicable to each
indemnifying party of any action

                                       20
<Page>

commenced against it in respect of which indemnity may be sought hereunder, but
failure to so notify an indemnifying party shall not relieve such indemnifying
party from any liability hereunder to the extent it is not materially prejudiced
as a result thereof, and in any event shall not relieve it from any liability
which it may have otherwise than on account of this indemnity agreement. In the
case of parties indemnified pursuant to Section 6(a) above, counsel to the
indemnified parties shall be selected by the Agent, and, in the case of parties
indemnified pursuant to Section 6(b) above, counsel to the indemnified parties
shall be selected by the Company and the Bank. An indemnifying party may
participate at its own expense in the defense of any such action; provided,
however, that counsel to the indemnifying party shall not (except with the
consent of the indemnified party) also be counsel to the indemnified party. In
no event shall the indemnifying parties be liable for fees and expenses of more
than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances. No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

               (d)    SETTLEMENT WITHOUT CONSENT IF FAILURE TO REIMBURSE. If at
any time an indemnified party shall have validly requested an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Section 6(a)(2) effected without its written consent if
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

SECTION 7.     CONTRIBUTION.

          In order to provide for just and equitable contribution in
circumstances under which the indemnification provided for in Section 6 hereof
is for any reason held to be unenforceable by an indemnified party in respect of
any losses, liabilities, claims, damages or expenses referred to therein, then
each indemnifying party shall contribute to the aggregate amount of such losses,
liabilities, claims, damages and expenses incurred by such indemnified party, as
incurred, (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Bank, on the one hand, and the Agent,
on the other hand, from the offering of the Securities pursuant to this
Agreement or (ii) if the allocation provided by clause (i) is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and the Bank, on the one hand, and the Agent, on the other hand, in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

                                       21
<Page>

          In order to determine the relative benefits received by the Company
and the Bank, on the one hand, and the Agent, on the other hand, the parties
hereto agree that in connection with the offering of the Securities pursuant to
this Agreement, the Agent shall be responsible for that portion represented by
the percentage that the maximum aggregate marketing fees appearing on the cover
page of the Prospectus bears to the maximum aggregate gross proceeds appearing
thereon and the Company and the Bank are responsible for the balance.

          The relative fault of the Company and the Bank, on the one hand, and
the Agent, on the other hand, shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statements of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Company and the Bank or by the Agent and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

          The Company and the Bank and the Agent agree that it would not be just
and equitable if contribution pursuant to this Section 7 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7. The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

          Notwithstanding the provisions of this Section 7, the Agent shall not
be required to contribute any amount in excess of the aggregate marketing fees
to which the Agent is entitled and actually paid pursuant to this Agreement
received pursuant to Section 2 of this Agreement.

          No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

          For purposes of this Section 7, each person, if any, who controls the
Agent within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934
Act and the respective partners, directors, officers, employees and agents of
such Agent or any such controlling person shall have the same rights to
contribution as the Agent, while each officer and director of the Company and
the Bank, and each person, if any, who controls the Company and the Bank within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company and the Bank.

SECTION 8.     REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY.

          All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers of the Company and the Bank
submitted pursuant hereto, shall remain operative and in full force and effect,
regardless of any investigation made by or on behalf of any Agent or controlling
person, or by or on behalf of the Company and the Bank, and shall survive
delivery of the Securities to the Purchasers thereof.

                                       22
<Page>

SECTION 9.     TERMINATION OF AGREEMENT.

               (a)    The Agent may terminate this Agreement, by notice to the
Company and the Bank, at any time at or prior to Closing Time (i) if there has
been, since the date of this Agreement or since the respective dates as of which
information is given in the Registration Statement, any Material Adverse Effect;
(ii) if there has occurred any material adverse change in the financial markets
in the United States or elsewhere or any outbreak of hostilities or escalation
thereof or other calamity or crisis the effects of which, in the judgment of the
Agent, are so material and adverse as to make it impracticable to market the
Securities or to enforce contracts, including subscriptions or orders, for the
sale of the Securities; (iii) if trading generally on either the New York Stock
Exchange or the NASDAQ has been suspended, or minimum or maximum prices for
trading have been fixed, or maximum ranges for prices for securities have been
required, by either the New York Stock Exchange, the NASD or by order of the
Commission or any other governmental authority, or if a banking moratorium has
been declared by either Federal, New York or Connecticut authorities; (iv) if
any condition specified in Section 5 (other than Section 5(b)) shall not have
been fulfilled when and as required to be fulfilled; (v) if there shall have
been such material adverse change in the condition or prospects of the Company
or the Bank or the prospective market for the Company's securities as in the
Agent's good faith opinion would make it inadvisable to proceed with the
offering, sale or delivery of the Securities; or (vi) if the Company is unable
to sell at least the total minimum of Securities, as disclosed on the cover of
the Prospectus, or if the Offering is not consummated for any other reason,
prior to ___________, 2005.

               (b)    If this Agreement is terminated pursuant to this Section,
the Company shall notify the subscription agent who shall refund to any persons
who have subscribed for any of the Securities the full amount which it may have
received from them, without interest, as provided in the Prospectus, such
termination shall be without liability of any party to any other party except
that the provisions of Section 4 hereof relating to reimbursement of expenses
and the provisions of Sections 6 and 7 hereof shall survive any termination of
this Agreement.

offered is referred to herein as the "Securities," with the specific details of
the transaction subject to the terms and conditions stated in the Agency
Agreement (the "Agency Agreement") to be entered into by the Company and Sandler
O'Neill & Partners L.P. (the "Agent").

     The undersigned, to facilitate the marketing of the Securities and in
consideration of the Company and the Agent entering into the Agency Agreement,
hereby irrevocably confirms and agrees for the benefit of the Company and the
Agent that during the period beginning from the date hereof and continuing to
and including the date 180 days after the Closing Date (as such term is defined
in the Agency Agreement) (the "Lock-Up Period"), the undersigned will not sell,
offer, agree to sell, contract to sell, hypothecate, pledge, grant any option to
purchase, make any short sale or otherwise dispose of or hedge, directly or
indirectly, any shares of Common Stock or securities convertible into,
exchangeable or exercisable for any shares of Common Stock or warrants or other
rights to purchase shares of Common Stock or any other securities of the Company
that are substantially similar to the Common Stock, whether now owned or
hereafter acquired, owned directly by the undersigned (including holding as a
custodian) or with respect to which the undersigned has or may be deemed to have
beneficial ownership in accordance with the rules and regulations of the
Securities and Exchange Commission (collectively, the "UNDERSIGNED'S SHARES") or
publicly announce an intention to do any of the foregoing.

     The foregoing restriction is expressly agreed to preclude the undersigned
from engaging in any hedging or other transaction or arrangement that is
designed to, or which reasonably could be expected to, lead to or result in a
sale, disposition or transfer, in whole or in part, of any of the economic
consequences of ownership of the Undersigned's Shares, whether any such
transaction is to be settled by delivery of Common Stock or other securities, in
cash or otherwise, even if such shares would be disposed of by someone other
than the undersigned. Such prohibited hedging or other transactions would
include, without limitation, any short sale or any purchase, sale or grant of
any right (including, without limitation, any put or call option) with respect
to any of the Undersigned's Shares or with

                                      B - 1

Undersigned's Shares (i) as a BONA FIDE gift or gifts, provided that the donee
or donees thereof agree to be bound in writing by the restrictions set forth
herein, (ii) to any trust for the direct or indirect benefit of the undersigned
or the immediate family of the undersigned, provided that the trustee of the
trust agrees to be bound in writing by the restrictions set forth herein, and
provided further that any such transfer shall not involve a disposition for
value, or (iii) with the prior written consent of Agent. For purposes of this
Agreement, "immediate family" shall mean any relationship by blood, marriage or
adoption, not more remote than first cousin. The undersigned now has and, except
as contemplated by clause (i), (ii) or (iii) above, for the duration of this
Agreement will have, good and marketable title to the Undersigned's Shares, free
and clear of all liens, encumbrances, and claims whatsoever. The undersigned
also agrees and consents to the entry of stop transfer instructions with the
Company and its transfer agent and registrar against the transfer of the
Undersigned's Shares, except in compliance with the foregoing restrictions. In
furtherance of the foregoing, the Company is hereby authorized to decline to
make or authorize any transfer of securities if such transfer would constitute a
violation or breach of this Lock-Up Agreement (this "AGREEMENT").

     Notwithstanding the foregoing, if: (1) during the last 17 days of the
Lock-Up Period, the Company issues an earnings release or material news or a
material event relating to the Company occurs; or (2) prior to the expiration of
the Lock-Up Period, the Company announces that it will release earnings results
during the 16-day-period beginning on the last day of the Lock-Up Period, the
restrictions imposed by this letter shall continue to apply until the expiration
of the 18-day period beginning on the issuance of the earnings release or the
occurrence of the material news or material event.

     The undersigned understands that the Company and the Agent are relying upon
this Agreement in proceeding toward consummation of the Offering. The
undersigned represents and warrants that the undersigned has full power and
authority to enter into this Agreement. The undersigned further understands that
this Agreement is irrevocable and agrees that the provisions of this Agreement
shall be binding also upon the successors, assigns, heirs and legal
representatives of the undersigned.

     The undersigned understands that, if the Agency Agreement (other than the
provisions thereof which survive termination) shall terminate or be terminated
prior to payment for and delivery of the Common Stock to be sold thereunder, the
undersigned shall be released from all obligations under this Agreement.
