                          FINANCIAL INSTITUTIONS, INC.

                                  Common Stock
                              --------------------

         This prospectus covers 75,000 shares of Financial Institutions, Inc.
common stock that we are offering to you as a shareholder of the Bank of Avoca
in exchange for your shares of common stock of Bank of Avoca.

         Financial Institutions is not soliciting your proxy. You are invited to
a special meeting of shareholders of the Bank of Avoca on March 28, 2002 at 1:30
p.m. local time at the Avoca United Methodist Church Building. At this meeting
you will be asked to vote on the merger of the Bank of Avoca with and into a

         If the merger is approved, you will receive shares of common stock of
Financial Institutions, Inc., and possibly cash, in exchange for your Bank of
Avoca common stock. The aggregate consideration will be determined as follows:
(i) if the average sales price of Financial Institutions common stock, meaning
the average of the daily closing prices per share on the NASDAQ National Market
for the 30 trading days immediately prior to the closing, is equal to or greater
than $20, the aggregate number of shares will be determined by dividing
$1,500,000 by the average sales price, or (ii) if the average sales price is
less than $20, the aggregate number of shares will equal 75,000 and, in
addition, Bank of Avoca shareholders will receive an aggregate amount of cash
equal to the difference between $1,500,000 and the product of the average sales
price multiplied by 75,000. As of the date of this prospectus, there were 5,000
shares of Bank of Avoca common stock outstanding.

         Financial Institutions, Inc. common stock is traded on the Nasdaq

FINANCIAL INSTITUTIONS, INC.
220 LIBERTY STREET
WARSAW, NEW YORK 14569
585-786-1100

         We are a financial holding company headquartered in Warsaw, New York,
which is located 45 miles southwest of Rochester and 45 miles southeast of
Buffalo. We operate as what is referred to in the financial industry as a
super-community financial holding company--a holding company that owns multiple
community banks and other financial services companies that are separately
managed. We own five commercial banks that provide consumer, commercial and
agricultural banking services in Western and Central New York State: Wyoming
County Bank, The National Bank of Geneva, Bath National Bank, The Pavilion State
Bank and First Tier Bank & Trust. We were formed in 1931 to facilitate the
management of three of these banks that had been primarily owned by the Humphrey
family during the late 1800s and early 1900s. In recent years, we have grown
through a combination of internal growth, the opening of new branch offices and
acquisitions. We also now provide varied financial services to our customers and
clients, including brokerage, trust, insurance and benefits consulting services.

         As a super-community financial holding company, our strategy has been
to manage our businesses on a decentralized basis. We feel that this strategy
provides us with the flexibility to efficiently serve our markets and respond to
local customer needs. While we generally operate on a decentralized basis, we
have consolidated selected operations and support functions in order to achieve
economies of scale, greater efficiency and operational consistency. We believe
that by expanding our use of the technology that we have already implemented,
and by further centralizing back-office and other common operations, we can
accommodate substantial additional growth without incurring proportionately
greater operational costs.

         Our banks provide a wide range of consumer and commercial banking
services and products to individuals, municipalities and small and medium size
businesses, including agribusiness. While our banks function as community banks,
we strive to provide our customers with a broad range of competitive services
generally provided only by larger, regional banks.

Acquisition III, Inc., its wholly owned subsidiary, with and into the Bank of
Avoca pursuant to an Agreement and Plan of Merger dated as of January 11, 2002
among Financial Institutions, Inc, FI Acquisition III, Inc. and Bank of Avoca.
This transaction contemplates that each issued and outstanding share of Bank of
Avoca common stock, par value $20 per share, will be converted into the right of
each Bank of Avoca shareholder to receive a pro rata share of an aggregate

sales price of Financial Institutions common stock, meaning the average of the
daily closing prices per share on the NASDAQ National Market for the 30 trading
days immediately prior to the closing, is equal to or greater than $20, the
aggregate number of shares will be determined by dividing $1,500,000 by such
average sales price, or (ii) if the average sales price is less than $20, the
aggregate number of shares will equal 75,000 and, in addition, each Bank of
Avoca shareholder will receive a pro rata share of an aggregate amount of cash
equal to the difference between $1,500,000 and the product of the average sales

                                  RISK FACTORS

         Prospective investors should carefully consider the risk factors set
forth below, as well as the other information contained in this Prospectus, in
evaluating the securities offered hereby. This Prospectus contains certain
forward-looking statements that involve risks and uncertainties. Our actual
results could differ materially from those anticipated in these forward-looking
statements as a result of certain factors, including those set forth below and
elsewhere in this Prospectus.

CHANGES IN INTEREST RATES COULD MAKE US LESS PROFITABLE

         Our profitability depends largely on our net interest income, which is
the difference between the interest we receive from loans and investments and
the interest we pay on deposit liabilities and borrowings. Changes in interest
rates may adversely affect our profitability. Interest rates are sensitive to
many factors, including general economic conditions and the policies of
government and regulatory authorities. Changes in the difference between short
and long-term interest rates, commonly known as the yield curve, may also harm
our business. If the difference between short-term and long-term interest rates
shrinks or disappears, we would earn less net interest income.

OUR BORROWERS MAY NOT REPAY US, OUR COLLATERAL MAY BE INSUFFICIENT AND OUR
DECENTRALIZED LENDING AUTHORITY CARRIES RISKS

         All lending involves the risk that borrowers may default on their loans
and that loans may be insufficiently collateralized. Most industry experts
believe that agricultural, commercial and consumer loans, which accounted for
approximately 79% of our total loans outstanding at December 31, 2001, expose a
lender to a greater risk of loss than one- to four-family residential loans,
which accounted for approximately 21% of our total loans outstanding at
December 31, 2001.

         The independent appraisals we use to value our collateral may overstate
such value of our collateral and we may use existing appraisals that may not be
current. Also, our banks may not be able to realize the full value of our
collateral in the event of a foreclosure. The value of collateral such as
farmland, farm equipment, construction equipment, cattle, crops and receivables
generated by agricultural and construction-related businesses may be adversely
affected by falling prices for farm commodities or a decline in construction
work in our area. Many of our commercial loans are collateralized by personal
guarantees of the owners of the farm or business obtaining the loan. In the
event the personal financial condition of the guarantors deteriorates, these
guarantees may be of limited value.

         There is additional lending risk inherent in our decentralized
management structure. Because most loans are made at the branch or individual
bank level, there are a number of loan officers with the ability to approve
loans. This increases the possibility of errors, noncompliance with underwriting
standards and fraud.

WE MAY FAIL TO IMPLEMENT OUR ACQUISITIONS SUCCESSFULLY, ACHIEVE SAVINGS AND
REALIZE THE OTHER ANTICIPATED BENEFITS FROM THE ACQUISITIONS BECAUSE OF
DIFFICULTIES IN INTEGRATING OUR BUSINESS OPERATIONS.

         We recently acquired Bath National Bank, a community bank based in
Bath, New York and the Burke Group, Inc., a full service benefits consulting
business located in Honeoye Falls, New York. The integration of the acquired
businesses following an acquisition are complex and time-consuming and present
us with challenges. As a result, we may not be able to operate the combined
company as effectively as we expect. We may also fail to achieve the anticipated
potential benefits of the acquisitions as quickly or as cost effectively as we
anticipate or may not be able to achieve those benefits at all. Specifically, we
will face significant challenges integrating the companies' organizations,
procedures and operations in a timely and efficient manner and retaining key
personnel. In addition, our management will have to dedicate substantial effort
to integrating the acquired businesses and branches and, therefore, its focus
and resources may be diverted from other strategic opportunities and from
operational matters. There may also be undisclosed liabilities that we assume
with the acquired business.

                                       4


IF WE LOSE ANY OF OUR KEY PERSONNEL, WE MAY NOT BE ABLE TO REPLACE THEM

         We are very dependent on our key personnel, including Peter G. Humphrey
and the presidents of our five banks. The loss of Mr. Humphrey or other members
of senior management could have an adverse effect on us. Qualified replacements
could be difficult to find or retain.

INTENSE COMPETITION COULD HURT OUR FINANCIAL PERFORMANCE OR CAUSE US TO LOSE
MARKET SHARE

         Our competition is intense, and we expect that it will continue. If we
are unable to compete effectively, our profitability will be reduced. We compete
with other commercial banks, savings banks, savings and loan associations,
credit unions, finance companies, mutual funds, insurance companies and other
financial institutions, as well as with retail stores which offer credit
programs and governmental agencies. Many of our competitors have greater
financial strength, marketing capability and name recognition than we do, and
operate on a statewide or nationwide basis. In addition, recent developments in
technology and mass marketing have permitted larger companies to market loans
more aggressively to our small business customers. Such advantages may give our
competitors opportunities to realize greater efficiencies and economies of scale
than we can. Competition for loans and deposits reduces interest rate spreads,
which reduces our net interest income.

IF THE ECONOMIC CONDITIONS IN OUR MARKET AREAS DETERIORATE, OUR BORROWERS MAY BE
UNABLE TO PAY THEIR LOANS

         Adverse changes in our local market economies may have a material
adverse effect on our business. Our business depends heavily on general economic
conditions within our primary market areas, which have seen limited economic
growth in the past decade. Our primary market areas are substantially rural,
which may limit our prospects for growth.

WE MAY NOT BE ABLE TO UNDERTAKE ACTIVITIES THAT WE WOULD LIKE TO BECAUSE OF
GOVERNMENTAL REGULATIONS; CHANGES IN GOVERNMENTAL REGULATIONS MAY FORCE US TO
ALTER THE WAY WE CONDUCT OUR BUSINESS

         We and our banks operate in a highly regulated environment and are
subject to supervision and examination by several federal and state regulatory
agencies, including the Federal Reserve Board, the FDIC, the Office of the
Comptroller of the Currency and the New York State Banking Department. The laws
and regulations administered by these agencies are intended primarily for the
protection of depositors and customers, rather than for the benefit of investors
in our stock, and may adversely affect our business. Federal laws and
regulations govern numerous matters including adequate capital and financial
condition, permissible types, amounts and terms of extensions of credit and
investments, permissible non-banking activities and restrictions on dividend
payments. The federal and state regulators have extensive discretion and power
to prevent or remedy unsafe or unsound practices or violations of law by banks
and bank holding companies. Following periodic examinations by regulatory
agencies, we may be required, among other things, to change our asset valuations
or the amounts of required loss allowances or to restrict our operations. The
banks' operations are also subject to a wide variety of state and federal
consumer protection and similar statutes and regulations. Such federal and state
regulatory restrictions limit the manner in which Financial Institutions and the
banks may conduct business and obtain financing. We are subject to changes in
federal and state laws, as well as changes in regulations and governmental
policies, income tax laws and accounting principles. The Federal Reserve Board
has adopted a policy that can require a financial holding company to contribute
cash to its bank subsidiaries, which could have the effect of decreasing funds
available for distributions to our shareholders. In addition, in certain
circumstances we could be required to guarantee the capital plan of an
undercapitalized bank subsidiary.

YOU MAY NOT RECEIVE DIVIDENDS ON YOUR COMMON STOCK AND THE AMOUNT OF DIVIDENDS
THAT YOU DO RECEIVE MAY BE LESS THAN WE HAVE PAID IN THE PAST

         While we currently pay cash dividends on our common stock, there can be
no assurance that we will do so in the future. The declaration and payment of
dividends on our common stock will depend upon our earnings and financial
condition, liquidity and capital requirements, the general economic and
regulatory climate, specific regulatory requirements, our ability to service any
equity or debt obligations senior to the common stock and other factors deemed
relevant by our Board of Directors.

YOU WILL HAVE A MINIMAL INFLUENCE ON SHAREHOLDER DECISIONS

                                       5

         A small number of our shareholders are able to significantly influence
our management policies and decisions and matters which require a shareholder
vote. Their interests, and the interests of the executive officers and directors
who are members of the Humphrey family, may differ from the interests of other
shareholders with respect to management issues. As of December 31, 2001, our
executive officers and directors beneficially own 1,152,445, or 10.6%, of the
outstanding shares of common stock. In addition W. J. Humphrey, Jr., Margaret H.
Wyckoff, Gail Humphrey their children and grandchildren, and their respective
immediate family members own a significant portion of the outstanding shares of
common stock. In addition, Wyoming County Bank beneficially owns 643,435, or
5.8%, of the outstanding shares of common stock in its capacity as trustee of
trusts established by members of the Humphrey family.

         Possible future sales of our common stock by our directors, officers
and other shareholders could cause the market value of our common stock to
decline and may make raising equity capital more difficult.

                            DESCRIPTION OF THE MERGER

         On January 11, 2002 the parties executed a definitive merger agreement
whereby Financial Institutions, Inc. has agreed to merge a wholly owned
subsidiary with and into the Bank of Avoca subject to the approval by the
shareholders of the Bank of Avoca.

BANK OF AVOCA REASONS FOR THE MERGER

         In reaching its decision to approve the merger agreement and the
merger, the board of directors of the Bank of Avoca consulted with its
management team and advisors and independently considered the proposed merger
agreement and the transactions contemplated under such merger agreement. The
board of directors of the Bank of Avoca considered the advantages to its
customers and employees of being part of a larger bank holding company and the
stockholder benefit created by exchanging shares of the privately held Bank of
Avoca for shares of the publicly held Financial Institutions.

FINANCIAL INSTITUTIONS REASONS FOR THE MERGER

         In reaching its decision to approve the merger agreement and the
merger, the board of directors of Financial Institutions consulted with its
management team and advisors and independently considered the proposed merger
agreement and the transactions contemplated under such merger agreement. The
board of directors of Financial Institutions evaluated the opportunity to expand
the market presence its subsidiary, Bath National Bank, through the acquisition
of the Bank of Avoca.

MERGER AGREEMENT

         Financial Institutions, Inc. has agreed to merge FI Acquisition III,
Inc., its wholly owned subsidiary, with and into the Bank of Avoca pursuant to
an Agreement and Plan of Merger dated as of January 11, 2002 among Financial
Institutions, Inc, FI Acquisition III, Inc. and Bank of Avoca. This transaction
contemplates that each issued and outstanding share of Bank of Avoca common
stock, par value $20 per share, will be converted into the right of each Bank of
Avoca shareholder to receive a pro rata share of an aggregate number of shares
of Financial Institutions common stock, and possibly cash, to be determined on
the closing date of the merger as follows: (i) if the average sales price of
Financial Institutions common stock, meaning the average of the daily closing
prices per share on the NASDAQ National Market for the 30 trading days
immediately prior to the closing, is equal to or greater than $20, the aggregate
number of shares will be determined by dividing $1,500,000 by such average sales
price, or (ii) if the average sales price is less than $20, the aggregate number
of shares will equal 75,000 and, in addition, each Bank of Avoca shareholder
will receive a pro rata share of an aggregate amount of cash equal to the
difference between $1,500,000 and the product of the average sales price
multiplied by 75,000. Subsequently, the Bank of Avoca will merge with and into
Bath National Bank and become a branch of Bath National Bank.

         By way of example, if the average sales price of Financial Institutions
common stock is $25, each share of Bank of Avoca common stock will entitle the
holder to receive twelve shares of Financial Institutions common stock.

agreement. You should read carefully the merger agreement which is attached as

MATERIAL INCOME TAX CONSEQUENCES

         The following is a summary of material U.S. federal income tax
consequences of the merger to holders or other beneficial owners of Bank of
Avoca common stock that are U.S. persons and that hold such stock as a capital
asset as defined in Section 1221 of the Internal Revenue Code of 1986, as
amended (generally, property held for investment is a capital asset). For these
purposes, you are a U.S. person if you are either (1) a citizen or resident of
the United States for U.S. federal income tax purposes, (2) a corporation or
partnership created or organized in or under the laws of the United States or
any political subdivision thereof, (3) an estate, the income of which is subject
to U.S. federal income tax regardless of the source or (4) a trust with respect
to which a court within the United States is able to exercise primary
supervision over your administration and one or more U.S. persons have the
authority to control all your substantial decisions. This summary is based on
the Internal Revenue Code, Treasury regulations, administrative rulings and
court decisions, all as in effect as of the date hereof and all of which are
subject to change at any time (possibly with retroactive effect). This summary
is not a complete description of all tax consequences of the merger and, in
particular, may not address U.S. federal income tax considerations applicable to
stockholders subject to special treatment under U.S. federal income tax law. In
addition, no information is provided herein with respect to the tax consequences
of the merger under applicable foreign, state or local laws.

                                       10


         The material U.S. federal income tax consequences of the merger are as
follows:

         o    the merger will constitute a reorganization within the meaning of
              Section 368(a)(1) of the Internal Revenue Code;

         o    no gain or loss will be recognized by the holders of Bank of
              Avoca common stock who exchange their Bank of Avoca common stock
              for Financial Institutions common stock pursuant to the merger,
              except with respect to any cash received in lieu of a fractional
              share of Financial Institutions common stock;

         o    the aggregate tax basis of the Financial Institutions common
              stock received in the merger by each holder of Bank of Avoca
              common stock will be the same as the aggregate tax basis of the
              Bank of Avoca common stock surrendered in exchange therefor,
              reduced by any amount of tax basis allocable to a fractional
              share interest in Financial Institutions common stock for which
              cash is received;

         o    the holding period of the Financial Institutions common stock
              received in the merger by a former Bank of Avoca stockholder will
              include the holding period of the Bank of Avoca common stock
              surrendered in exchange therefor;

         o    a Bank of Avoca stockholder who receives cash in lieu of a
              fractional share interest in Financial Institutions common stock
              pursuant to the merger will be treated as having received such
              cash in exchange for such fractional share interest and generally
              will recognize capital gain or loss on such deemed exchange in an
              amount equal to the difference between the amount of cash
              received and the tax basis of the Bank of Avoca common stock
              allocable to such fractional share interest; and

         o    no gain or loss will be recognized by Financial Institutions,
              Financial Institutions shareholders, or Bank of Avoca as a result
              of the merger.

         Under the U.S. backup withholding rules, as a holder of Bank of Avoca
common stock you may be subject to backup withholding at the rate of 31% on any
cash received in lieu of fractional shares of Financial Institutions common
stock, unless you (1) are a corporation or come within other exempt categories
and, when required, demonstrate this fact or (2) provide a correct taxpayer
identification number, certify that you are not subject to backup withholding
and otherwise comply with applicable requirements of the backup withholding
rules. Any amount withheld under these rules will be credited against your
federal income tax liability provided you furnish the required information to
the IRS. If you do not comply with the backup withholding rules, you may be
subject to penalties imposed by the IRS.

         The preceding summary does not purport to be a complete analysis or
discussion of a potential tax effect relevant to the merger. You are urged to
consult with your own tax advisors regarding the U.S. federal income and other
tax consequences of the merger to you, under state, local and foreign tax laws.

         Section 1.1 The Merger. Upon the terms and subject to the conditions of
this Agreement, at the Effective Time (as defined in Section 1.3), Merger
Subsidiary shall be merged with and into the Company and the separate existence
of Merger Subsidiary shall thereupon cease, and the Company shall continue as
the surviving corporation (the "Surviving Corporation") and as a wholly-owned
subsidiary of Buyer. As soon as reasonably practicable after the consummation of
the Merger, the Buyer shall cause the Surviving Corporation to be merged with
and into Bath National Bank, with Bath National Bank surviving such merger (the
"Bank Merger").

         Section 1.2 Closing. Subject to the satisfaction or waiver of the
conditions set forth in Article VIII hereof, the closing of the Merger will take
place as promptly as practicable (and in any event within ten business days)
after satisfaction or waiver of the conditions set forth in Article VIII (the
"Closing Date"), at the offices of Nixon Peabody LLP, Rochester, New York,
unless this Agreement shall have been terminated pursuant to Section 9.1. It is
anticipated that the Closing Date will occur on or prior to March 29, 2002.

         Section 1.3 Effective Time of the Merger. Subject to the provisions of
this Agreement, as soon as practicable on the Closing Date, the parties shall
file, and the Merger shall become effective upon the filing of, a certificate of
merger ("Certificate of Merger") pursuant to and in compliance with this
Agreement and Section 907 of Business Corporation Law of the State of New York
(the "New York Law") with the Secretary of State of the



                                       2


State of New York. When used in this Agreement, the term "Effective Time" shall
mean the time at which the Certificate of Merger has been filed and become
effective in accordance with New York Law.

         Section 1.4 Effect of the Merger. The Merger shall, from and after the
Effective Time, have all the effects provided by applicable New York Law. If at
any time after the Effective Time the Surviving Corporation shall determine that
any further deeds, conveyances, assignments or any other acts are necessary,
desirable or proper to vest, perfect or confirm, of record or otherwise, in the
Surviving Corporation, the title to any property or rights of Merger Subsidiary
or the Company, or otherwise to carry out the purposes of this Agreement, the
Company and the Merger Subsidiary agree that the Surviving Corporation and its
officers and directors shall execute and deliver all such deeds, conveyances,
assignments and other documents or instruments, and do all things necessary,
desirable or proper to vest, perfect or confirm title to such property or rights
in the Surviving Corporation and otherwise to carry out the purposes of this
Agreement, and that the officers and directors of the Surviving Corporation are
fully authorized in the name of each of the Company and the Merger Subsidiary or
otherwise to take any and all such action.

         Section 1.5 Modifications of Structure. Notwithstanding any provision
of this Agreement to the contrary, Buyer, with the prior written consent of the
Company, which consent shall not be unreasonably withheld, may elect to modify
the structure of the transactions contemplated hereby so long as (i) there are
no material adverse federal income tax consequences to the Shareholders as a
result of such modification, (ii) the consideration to be paid to the
Shareholders under this Agreement is not thereby changed in kind or reduced in
amount solely because of such modification, and (iii) such modification will not
be likely to materially delay or jeopardize receipt of any required regulatory
approvals or impair or prevent the satisfaction of any conditions to the
Effective Time.

         Section 1.6 Dissenters' Rights. Notwithstanding any provision of this
Agreement to the contrary, Company Shares that are outstanding immediately prior
to the Effective Time and that are held by Shareholders who have not voted in
favor of the Merger or consented thereto in writing and who have delivered to
the Company written demand for appraisal of the fair value of such Company
Shares in accordance with New York Law (collectively, the "Dissenters' Shares")
shall not be converted into or represent the right to receive the Merger
Consideration. Such Shareholders instead shall be entitled to receive payment of
the fair value of all Company Shares held by them in accordance with the
provisions of New York Law, except that all Dissenters' Shares held by
Shareholders who shall have failed to perfect or who effectively shall have
withdrawn or otherwise lost their dissenters' rights under New York Law shall
thereupon be deemed to have been converted into and to have become exchangeable,
as of the Effective Time, for the right to receive, without any interest
thereon, the Merger Consideration in the manner provided in Section 3.1 below.
The Company shall give Buyer (i) prompt notice of any written demands for
appraisal of the fair value of any Company Shares, attempted withdrawals of such
demands and any other instruments served pursuant to New York Law and received
by the Company relating to Shareholders' rights of appraisal, and (ii) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal under New York Law. The Company shall not, without the prior
written consent of Buyer, voluntarily make any payment with respect to, or
settle or offer to settle, any such demand for appraisal.

restated to read substantially in the form of the Certificate of Incorporation
of the Merger Subsidiary as in effect immediately prior to the Effective Time

         Section 2.2 By-laws. At the Effective Time, the By-laws of the

Schedule 2.3 hereto shall be the directors and officers of the Surviving
Corporation immediately after the Effective Time and shall hold the offices set
forth

                                       3

                                   ARTICLE III

                              CONVERSION OF SHARES

         Section 3.1 Merger Consideration.

                  (a) Subject to the provisions of this Agreement, by virtue of
the Merger and without any action on the part of Buyer, the Merger Subsidiary,
the Company, or any Shareholder, at the Effective Time, the holders of Company
Shares issued and outstanding immediately prior to the Effective Time (other
than Company Shares canceled in accordance with this Agreement) shall be
entitled to receive, as aggregate consideration for the Merger, (i) in the event
that the Average Sales Price is equal to or greater than $20, that number of
shares of Buyer Stock determined by dividing $1,500,000 by the Average Sales
Price, or (ii) in the event that the Average Sales Price is less than $20,
75,000 shares of Buyer Stock plus an amount of cash equal to the difference
between $1,500,000 and the product of the Average Sales Price multiplied by
75,000 (the consideration determined in accordance with (i) or (ii), as the case
may be, is hereafter referred to as the "Merger Consideration") payable to each
Shareholder pro rata (the "Exchange Ratio"). As of the Effective Time, each
share of Company Common Stock held by the Company as treasury stock shall be
canceled and retired without any consideration being paid or exchanged therefor.

                  (b) Subject to the provisions of this Agreement, at the
Effective Time each share of common stock of Merger Subsidiary outstanding
immediately prior to the Merger shall be converted, by virtue of the Merger and
without any action on the part of the holder thereof, into 25 shares of the
common stock of the Surviving Corporation, par value of $20 per share, which
shares shall constitute all of the issued and outstanding capital stock of the
Surviving Corporation and shall be owned by Buyer.

                  (c) As soon as reasonably practicable after the Effective
Time, Buyer shall cause the Surviving Corporation to merge with and into Bath
National Bank, with Bath National Bank surviving such merger.

         3.2 Shareholders' Rights at the Effective Time. On and after the
Effective Time, the certificates that immediately prior to the Effective Time
represented the Company Shares (the "Certificates") shall cease to represent any
rights with respect to the Company and shall only represent the right to receive
the Merger Consideration and holders of Certificates theretofore evidencing
Company Shares shall cease to have any rights as Shareholders of the Company,
except as otherwise provided herein or by law.

         3.3 Surrender and Exchange of Share Certificates.

                  (a) On the Closing Date, or within three Business Days
thereafter, Buyer or its agent shall cause to be mailed to each Shareholder: (i)
a letter of transmittal (the "Letter of Transmittal"), and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for such
Shareholder's portion of the Merger Consideration determined in accordance with
the provisions of Section 3.1 hereof.

                  (b) At or prior to the Effective Time, Buyer shall deposit or
cause to be deposited in a separate bank account cash in an amount equal to that
portion of the aggregate Merger Consideration payable in cash to Shareholders at
the Effective Time pursuant to Section 3.1(a)(ii), if any.

                  (c) After the Effective Time, each Shareholder shall surrender
and deliver each Certificate held by such Shareholder (or, in the event any
Certificate is claimed to have been lost, stolen or destroyed, an affidavit and
indemnity bond as provided in Section 3.3(e) hereof) to Buyer or its agent
together with a duly completed and executed Letter of Transmittal. Within three
Business Days after receipt of a duly completed and executed Letter of
Transmittal, together with the related Certificate (or affidavit and indemnity
bond as provided in Section 3.3(e) hereof), Buyer shall deliver or cause to be
delivered to each Shareholder (i) one or more duly executed certificates
representing that number of fully paid and non-assessable shares of Buyer Stock
equal to such Shareholder's portion of the Merger Consideration determined in
accordance with the provisions of Section 3.1 hereof and (ii) a check in

                                       4


the amount equal to the cash that such holder has the right to receive pursuant
to Section 3.1(a)(ii) hereof, if any. Until so surrendered and exchanged, each
Certificate shall after the Effective Time be deemed for all purposes to
evidence only the right to receive the Merger Consideration as provided in
Section 3.1 hereof.

                  (d) At the Effective Time, the stock transfer books of the
Company shall be closed and no transfer of Company Shares shall be made
thereafter, other than transfers that have occurred prior to the Effective Time.
In the event that, after the Effective Time, Certificates are presented for
transfer to the transfer agent for the Company, the Merger Subsidiary or the
Buyer, they shall be delivered to the Buyer or its agent and exchanged for the
Merger Consideration payable pursuant to Section 3.1 hereof.

                  (e) Neither the Company, Merger Subsidiary or Buyer shall be
liable to any holder of Company Shares with respect to any portion of the Merger
Consideration delivered to any public official pursuant to any applicable
abandoned property, escheat or similar law, rule, regulation, statute, order,
judgment or decree.

                  (f) In the event that any Shareholder claims that any
Certificate owned by such Shareholder has been lost, stolen or destroyed, such
Shareholder shall execute and deliver to Buyer an affidavit attesting to that
fact, in form and substance reasonably satisfactory to Buyer, together with a
bond or other security, as Buyer may reasonably require, and Buyer shall
thereupon deliver or cause to be delivered to such Shareholder one or more duly
executed certificates representing the Merger Consideration determined in
accordance with the provisions of Section 3.1 hereof with respect to such lost,
stolen or destroyed Certificate.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Section 4.4 No Conflicts, Required Filings and Consents.

                  (a) None of the execution and delivery of this Agreement by
the Company, the consummation by the Company of the transactions contemplated

                  (b) None of the execution and delivery of this Agreement by

         Section 4.8 Employee Benefit Plans.

                  (a) Section 4.8(a) of the Company Disclosure Schedule sets
forth a complete and correct list of all employee benefit or compensation plans,
agreements and arrangements, including "employee benefit plans," as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), including but not limited to, plans, agreements or arrangements
relating to former employees, including but not limited to, retiree medical
plans and life insurance sponsored, maintained or contributed to by the Company
or any entity which is considered one employer with the Company under Section
4001 of ERISA or Section 414 of the Code (an "ERISA Affiliate") (together such
plans, agreements or arrangements are referred to as the "Company Benefit
Plans"). The Company and its ERISA Affiliates have complied with the terms of
all Company Benefit Plans, and no default exists with respect to the obligations
of the Company or any of its ERISA Affiliates under such Company Benefit Plans.

                  (b) Except as set forth in Section 4.8(b) of the Company
Disclosure Schedule, each Company Benefit Plan is in writing and the Company has

Plan, including without limitation, (i) a copy of each trust or other funding
arrangement, (ii) each summary plan description and summary of material
modifications, (iii) the most recently filed Internal Revenue Service ("IRS")
Form 5500, including all attachments thereto, (iv) the most recently received

                  (c) Neither the Company nor any ERISA Affiliate has any
express or implied commitment to (i) create or incur liability with respect to,
or to cause to exist, any other employee benefit plan, program or arrangement,
(ii) enter into any contract or agreement to provide compensation or benefits to
any individual, or (iii) modify, change or terminate any Company Benefit Plan,
other than with respect to a modification, change or termination required by
ERISA or the Code.

         Section 4.9 ERISA.

                  (a) Each of the Company Benefit Plans which is intended to
meet the requirements of Section 401(a) of the Internal Revenue Code of 1986, as
amended (the "Code"), has been determined by the IRS to be "qualified," within
the meaning of such Section of the Code and the Company has no Knowledge of any
circumstances which could result in revocation of such determination. No Company
Benefit Plan is subject to Title IV of ERISA and the Company and its current and
former ERISA Affiliates have never sponsored, maintained or contributed to an
employee benefit plan that is subject to Title IV of ERISA. There have not been
any non-exempt "prohibited transactions," as such term is defined in Section
4975 of the Code or Section 406 of ERISA, involving the Company Benefit Plans
which could subject the Company, its ERISA Affiliates or Buyer to the penalty or
tax imposed under Section 502(i) of ERISA or Section 4975 of the Code. Except as
set forth in Section 4.9(a) of the Company Disclosure Schedule, neither the
execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby will (i) result in any payment (including,
without limitation, severance, unemployment compensation or golden parachute)
becoming due to any director or employee of the Company, (ii) increase any
benefits otherwise payable under any Company Benefit Plan, or (iii) result in
the acceleration of the time of payment or vesting of any such benefits.

                  (b) No notice of a "reportable event," within the meaning of
Section 4043 of ERISA for which the 30-day reporting requirement has not been
waived, has been required to be filed for any Company Benefit Plan which is an
"employee pension benefit plan" within the meaning of Section 3(2) of ERISA and
which is intended to meet the requirements of Section 401(a) of the Code (a
"Pension Plan"), or by the Company or any ERISA Affiliate within the 60-month
period ending on the date hereof.

                                       7


                  (c) As of the date hereof, neither any Pension Plan nor any
single-employer plan of an ERISA Affiliate has an "accumulated funding
deficiency" (whether or not waived) within the meaning of Section 412 of the
Code or Section 302 of ERISA. Neither the Company nor its ERISA Affiliates has
provided, or is required to provide, security to any Pension Plan or to any
single-employer plan of an ERISA Affiliate pursuant to Section 401(a)(29) of the
Code. Neither the Company nor any ERISA Affiliate has incurred any liability
under, arising out of or by operation of Title IV of ERISA, including, without
limitation, any material liability in connection with the termination or
reorganization of any employee pension benefit plan subject to Title IV of
ERISA, and no fact or event exists which could give rise to any such material
liability.

                  (d) The Company and its ERISA Affiliates are not and have
never been a sponsor or liable with respect to any multi-employer plan within
the meaning of Section 3(37) of ERISA.

                  (e) All contributions and premiums required by law or by the
terms of any Company Benefit Plan in which employees of the Company and its
ERISA Affiliates participate or any agreement relating thereto have been timely
made (without regard to any waivers granted with respect thereto).

                  (f) Each of the Company Benefit Plans has been maintained in
accordance with its terms, applicable collective bargaining agreements and all
provisions of applicable laws and regulations except to the extent that any
failure to be so maintained will not have a Material Adverse Effect on the
Company. All amendments and actions required to bring each of such Benefit Plans
into conformity in all material respects with all of the applicable provisions
of ERISA and other applicable laws and regulations have been made or taken
except to the extent that such amendments or actions are not required by law to
be made or taken until a date after the Closing Date.

                  (g) The liabilities of each Company Benefit Plan or Pension
Plan that has been terminated or otherwise wound up, have been fully discharged
in compliance with applicable law.

                  (h) Neither the Company nor any ERISA Affiliate maintains a
welfare benefit plan providing continuing benefits after the termination of
employment (other than as required by Section 4980B of the Code and at the
former employee's own expense) except as disclosed in Section 4.9(h) of the
Company's Disclosure Schedule, and the Company and each of the ERISA Affiliates
have complied in all material respects with the notice and continuation
requirements of Section 4980B of the Code and the regulations thereunder.

                  (i) No payments or benefits under any Company Benefit Plan or
other agreement of the Company will be considered excess parachute payments
under Section 280G of the Code or trigger a limitation on the ability of the
Company to take a deduction under Section 162(m) of the Code.

                  (j) There has been no violation of ERISA with respect to the
filing of applicable returns, reports, documents and notices regarding any of
the Company Benefit Plans with the Secretary of Labor or the Secretary of the
Treasury or the furnishing of such notices or documents to the participants or
beneficiaries of the Company Benefit Plans which, either individually or in the
aggregate, could result in a Material Adverse Effect to the Company.

                  (k) There are no pending or threatened legal proceedings,
claims or administrative actions which have been asserted or instituted against
any of the Company Benefit Plans, the assets of any such Plans or the Company or
any ERISA Affiliate or the plan administrator or any fiduciary of the Company
Benefit Plans with respect to the operation of such plans, and, to the Knowledge
of the Company, there is no basis for the institution of any such proceedings,
claims or administrative actions.

         Section 4.10 Taxes. The Company has filed all federal, state and local
income, franchise, excise, real and personal property and other tax returns and
reports required to have been filed by it prior to the date hereof. All of such
returns and reports are true and correct in all material respects, and the
Company has paid or, prior to the Effective Time will pay, all taxes, interest
and penalties shown on such returns or reports as being due or (except to the
extent the same are contested in good faith) claimed to be due to any federal,
state, local or other taxing authority. The Company has paid and will pay all
installments of estimated taxes due on or before the Effective

                                       8


Time. All taxes and state assessments and levies which the Company is required
by law to withhold or collect have been withheld or collected and have been paid
to the proper Governmental Entity or are held by the Company for such payment.
The Company has paid or made adequate provision in accordance with GAAP in the
financial statements of the Company for all taxes payable in respect of all
periods ending on or prior to the date of this Agreement and will have paid or
provided for all taxes payable in respect of all periods ending on or prior to
the Closing Date. As of the date hereof, all deficiencies proposed as a result
of any audits have been paid or settled.

         Section 4.11 Compliance with Applicable Laws.

                  (a) The Company holds all licenses, franchises, permits and
authorizations necessary for the lawful conduct of its business, except where

all SEC Documents required by the Securities Laws and all reports and notices
with the Nasdaq Stock Market Inc. required to be filed by the rules and
regulations of the Nasdaq Stock Market Inc. and the Exchange Act (collectively,

complete and correct as of their respective dates, in all material respects, and
neither any SEC Documents nor any Nasdaq Reports contain any untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements contained therein not misleading. Buyer and each of the Buyer's
Subsidiaries has filed all reports required by statute or regulation to be filed
with any federal or state bank regulatory agency, except where the failure to so
file would not have a Material Adverse Effect, and such reports were prepared in
accordance with the applicable statutes, regulations and instructions in
existence as of the date of filing of such reports in all material respects, and
none of the reports contain any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements contained
therein not misleading.

all material respects the consolidated financial position of Buyer and its
consolidated Subsidiaries as of the dates indicated and the consolidated results
of operations, changes in stockholders' equity and cash flows of Buyer and its
consolidated Subsidiaries for the periods then ended and each such financial
statement has been prepared in conformity with GAAP applied on a consistent
basis.

         Section 5.13 Information Supplied. None of the information supplied or
to be supplied by Buyer or Merger Subsidiary specifically for inclusion or
incorporation by reference in the Registration Statement will, at the time the
Registration Statement is declared effective by the SEC, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they are made, not misleading. The Registration
Statement will comply as to form in all material respects with the requirements
of the Securities Act, except that no representation or warranty is made by
Buyer or Merger Subsidiary with respect to statements made or incorporated by
reference therein based on information supplied by the Company specifically for
inclusion or incorporation by reference in the Registration Statement.

         Section 5.14 Disclosure. No representation or warranty by the Buyer or
Merger Subsidiary in this Agreement, no information provided by Buyer in writing
and no statement contained in any exhibit, list, certificate, document or
schedule delivered or to be delivered pursuant to this Agreement contains or
will contain any untrue statement of a material fact or omits or will omit any
material fact necessary in order to make the statement contained therein in
light of the circumstances under which they were made not misleading.

fees, expenses and charges, and the costs of reversing the conversion process,
if for any reason the Merger is not consummated in accordance with the terms of
this Agreement.

                  (a) From the date hereof through the Effective Time, the
Company shall afford to Buyer and Buyer's accountants, counsel and other
representatives full and complete access during normal business hours (and at
such other times as the parties may mutually agree) to the Company's properties,
assets, books, contracts, commitments, records and personnel so as to permit
Buyer to perform a due diligence review as contemplated by Section 9.1(h); and
during such period, shall furnish promptly to Buyer all information concerning
its business, properties and personnel as Buyer may reasonably request.

                                       18



                  (b) The Company shall not be required to provide access to or
to disclose information where such access or disclosure would violate or
prejudice the rights of its customers, jeopardize any attorney-client privilege
or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty
or binding agreement entered into prior to the date of this Agreement. The
parties hereto will advise each other in writing if, and make approximate
substitute disclosure arrangement under circumstances in which, the restrictions
of the preceding sentence apply. Furthermore, notwithstanding anything to the
contrary herein, the Company shall not be required to provide Buyer with any
information regarding a Takeover Proposal (as hereinafter defined) except as
required by Section 7.7 hereof. Buyer shall hold, and shall cause its employees,
agents and representatives to hold, in confidence all "Confidential Information"
in accordance with the terms of the Confidentiality Agreement dated July 11,
2001, by and between Buyer and the Company, which shall remain in full force and
effect in accordance with the terms thereof, including, without limitation, in
the event of termination of this Agreement. No investigation pursuant to this
Section 7.1 shall limit any representation or warranty of the Company or Buyer.

         Section 7.2 Shareholders' Meeting. The Company shall take all action
necessary, in accordance with applicable law and its Certificate of
Incorporation and By-laws, to convene the Company Special Shareholders Meeting
for the purpose of considering and taking action upon the Merger and this
Agreement.

         Section 7.3 Public Announcements. On or before the Closing Date, Buyer
and the Company shall not (nor shall they permit any of their respective
Affiliates to), without prior consultation with the other party and such other
party's review of and consent to any public announcement concerning the
transactions contemplated by this Agreement, issue any press release or make any
public announcement with respect to such transactions except such disclosures as
may be required by law. During such period, Buyer and the Company shall, to the
extent practicable, allow the other party reasonable time to review and comment
on such release or announcement in advance of its issuance and use reasonable
efforts in good faith to reflect the reasonable and good faith comments of such
other party, provided, however, no party shall be prevented from making any
disclosure required by law at the time so required. The parties intend that the
initial announcement of the terms of the Merger shall be made by joint press
release of Buyer and the Company.

         Section 7.4  Undertakings by the Company

                  (a) The Company shall provide Buyer, within ten (10) days of
the end of each calendar month, a written list of nonperforming assets (the term
"nonperforming assets," for purposes of this subsection, means (i) loans that
are "troubled debt restructuring" as defined in Statement of Financial
Accounting Standards No. 15, "Accounting by Debtors and Creditors for Troubled
Debt Restructuring," (ii) loans on nonaccrual, (iii) real estate owned, (iv) all
loans ninety (90) days or more past due as of the end of such month and (v)
impaired loans);

                  (b) On or before the Effective Time, and at the request of
Buyer, the Company shall establish, consistent with GAAP, such additional
accruals and reserves as may be necessary to conform the accounting reserve
practices and methods (including credit loss practices and methods) of the
Company to those of Buyer (as such practices and methods are to be applied to
the Company from and after the Closing Date) and Buyer's plans with respect to
the conduct of the business of the Company following the Merger and otherwise to
reflect Merger-related expenses and costs incurred by the Company, provided,
however, that the Company shall not be required to take such action (i) more
than two (2) business days prior to the Closing Date and (ii) unless Buyer
agrees in writing that all conditions to closing set forth in Section 8.3 have
been satisfied or waived (except for the expiration of any applicable waiting
periods); prior to the delivery by Buyer of the writing referred to in the
preceding clause, the Company shall provide Buyer a written statement, certified
without personal liability by the chief executive officer of the Company and
dated the date of such writing, that the representation made in Section 4.29
hereof is true as of such date or, alternatively, setting forth in detail the
circumstances that prevent such representation from being true as of such date;
and no accrual or reserve made by the Company or any of its Subsidiaries
pursuant to this subsection, or any litigation or regulatory proceeding arising
out of any such accrual or reserve, shall constitute or be deemed to be a breach
or violation of any representation, warranty, covenant, condition or other
provision of this Agreement or to constitute a termination event within the
meaning of Section 9.1 hereof. No action shall be required to be taken by the
Company pursuant to this Section 7.4 if, in the opinion of the Company's
independent accountants, such action would contravene GAAP.

         Section 7.5  Efforts; Consents.

applicable laws relating to the exchange of information, all the information
relating to the Buyer or the Company, as the case may be, which appear in any
filing made with, or written materials submitted to, any third party or any
Governmental Entities or Regulatory Authority in connection with the

each other with all information concerning themselves, their Subsidiaries,
directors, officers and shareholders and such other matters as may be reasonably
necessary or advisable in connection with any statement, filing, notice or
application made by or on behalf of the Buyer or the Company or any of their
respective Subsidiaries to any Governmental Entity or Regulatory Authority in
connection with the Merger and the other transactions contemplated by this
Agreement.

                  (d) The Buyer and the Company shall promptly advise and inform
each other upon receiving (and the Buyer shall so advise with respect to
communications received by any Affiliate of the Buyer) any communication,
written or oral, from any Governmental Entity or Regulatory Authority whose
consent or approval is required for consummation of the transactions
contemplated by this Agreement. To the extent that any such communication is in
writing, the receiving party shall furnish a copy to the other party.

                  (e) The Buyer shall, as promptly as practicable following the
preparation thereof, file the Registration Statement with the SEC and the
Company and the Buyer shall use all reasonable efforts to have the Registration
Statement declared effective under the Securities Act. The Buyer shall advise
the Company, promptly after the Buyer receives notice thereof, of the time when
the Registration Statement has become effective or any supplement or amendment
has been filed, of the issuance of any stop order or the suspension of the
qualification of the shares of capital stock issuable pursuant to the
Registration Statement, or the initiation or threat of any proceeding for any
such purpose, or of any request by the SEC for the amendment or supplement of
the Registration Statement or for additional information.

                  (f) The Buyer shall cause the shares of Buyer Common Stock to
be issued in the Merger to be approved for listing on the Nasdaq National
Market, subject to official notice of issuance, prior to the Closing Date.

         Section 7.6 Notice of Breaches. The Company shall give prompt notice to
Buyer, and Buyer or Merger Subsidiary shall give prompt notice to the Company,
of (i) any representation or warranty made by it contained in this Agreement
which has become untrue or inaccurate in any material respect, or (ii) the
failure by it to comply with or satisfy in any material respect any covenant,
condition, or agreement to be complied with or satisfied by it

                                       20


under this Agreement; provided, however, that such notification shall not excuse
or otherwise affect the representations, warranties, covenants or agreements of
the parties or the conditions to the obligations of the parties under this
Agreement.

         Section 7.7  Acquisition Proposals.

                  (a) The Company shall, and shall direct and cause its
officers, directors, employees, representatives and agents to, immediately cease
any discussions or negotiations with any parties that may be ongoing with
respect to a Takeover Proposal (as hereinafter defined). The Company shall not,
nor shall it permit any of its Subsidiaries to, nor shall it authorize or permit
any of its officers, directors or employees or any financial advisor, attorney,
accountant or other representative retained by it to, directly or indirectly:
(i) solicit, initiate or encourage, including by way of furnishing information,
or take any other action designed or reasonably likely to facilitate, including,
without limitation, any adoption of any rights or similar plan, the grant of any
option or proxy or otherwise except to Buyer, any inquiries or the making of any
proposal which constitutes, or may reasonably be expected to lead to, any
Takeover Proposal or (ii) subject to paragraph (b) of this Section 7.7, provide
any information or data to any third party in connection with any Takeover
Proposal or participate in any discussions or negotiations regarding any
Takeover Proposal. Without limiting the foregoing, it is understood that any
violation of the restrictions set forth in the preceding sentence by any officer
or director of the Company or any financial advisor, attorney, accountant, or
other representative of the Company, shall be deemed to be a breach of this
Section 7.7 by the Company. "Takeover Proposal" means any inquiry, proposal or
offer from any person relating to any direct or indirect acquisition or purchase
of 15% or more of the assets of the Company or 15% or more of any class of
equity securities of the Company, any tender offer or exchange offer that if
consummated would result in any person beneficially owning 15% or more of any
class of equity securities of the Company, any merger, consolidation, share
exchange, business combination, recapitalization, liquidation, dissolution or
similar transaction involving the Company (other than the transactions
contemplated by this Agreement) or any other transaction the consummation of
which could reasonably be expected to impede, interfere with, prevent or
materially delay the Merger or which would reasonably be expected to diminish
materially the benefits to Buyer of the transactions contemplated by this
Agreement.

                  (b) Except as set forth in this Section 7.7, neither the Board
of Directors of the Company nor any committee thereof shall: (i) withdraw or
modify, or propose publicly to withdraw or modify, in a manner adverse to Buyer,
or take any action not explicitly permitted by this Agreement that would be
inconsistent with, the approval or recommendation by such Board of Directors or
such committee of the Merger, (ii) approve or recommend, or propose publicly to
approve or recommend, any Takeover Proposal, (iii) provide any information or
data to any third party in connection with a Takeover Proposal or participate in
any discussions or negotiations regarding any Takeover Proposal or (iv) cause
the Company to enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement (each, an "Acquisition
Agreement") related to any Takeover Proposal. Notwithstanding the foregoing, in
the event that prior to the Effective Time the board of directors of the Company
determines in good faith, upon advice from outside counsel, that it is necessary
to do so in order to comply with their fiduciary duties under applicable law,
the board of directors of the Company may (subject to this and the following
sentences): (x) withdraw or modify its approval or recommendation of the Merger,
or (y) approve or recommend a Superior Proposal (as defined below) or terminate
this Agreement (and concurrently with or after such termination, if it so
chooses, cause the Company to enter into any Acquisition Agreement with respect
to any Superior Proposal), but in each of the cases set forth in this clause
(y), only at a time that is after the fifth (5th) day following Buyer's receipt
of written notice advising Buyer that the Board of Directors of the Company has
received a Superior Proposal, specifying the material terms and conditions of
such Superior Proposal and identifying the person making such Superior Proposal.
For purposes of this Agreement, a "Superior Proposal" means any bona fide
proposal made by a third party to acquire, directly or indirectly, for
consideration consisting of cash and/or securities, more than 50% of the Company
Shares then outstanding or all or substantially all the assets of the Company
and otherwise on terms which the board of directors of the Company determines in
its good faith judgment (based on the advice of a financial advisor mutually
acceptable to the Company and Buyer) to be materially more favorable to the
Company's shareholders than the Merger and for which third-party financing, to
the extent required, is then firmly committed.

                  (c) In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 7.7, the Company shall promptly (but in
any event within forty-eight hours of receipt) advise Buyer orally and in
writing of any request by any person for information about the Company or of any
Takeover Proposal, the material terms and conditions of such request or the
Takeover Proposal and the identity of the person making such request or

                                       21


the Takeover Proposal. The Company shall keep Buyer fully and promptly informed
of the status and details (including amendments or proposed amendments) of any
request by any person for information about the Company or of any Takeover
Proposal.

         Section 7.8 Related Agreements. Simultaneously with the execution and
delivery of this Agreement, or as otherwise provided below, and as material
consideration for the execution and delivery of this Agreement by Buyer and
Merger Subsidiary, each of the Persons listed on Schedule 7.8 to this Agreement
is entering into a Shareholders' Agreement in the form of Exhibit A hereto.

         Section 7.9 Advice of Changes. The Buyer and the Company shall each
promptly advise the other party of any change or event having a Material Adverse
Effect on it or which it believes would or would be reasonably likely to cause
or constitute a material breach of any of its representations, warranties or
covenants contained herein; provided, however, that the delivery of any notice
pursuant to this Section shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice.

         Section 7.10 Update of Disclosure Schedules. From time to time prior to
the Effective Time, the Company and the Buyer will promptly supplement or amend
their respective Disclosure Schedules to reflect any matter which, if existing,
occurring or known at the date of this Agreement, would have been required to be
set forth or described in such Disclosure Schedule or which is necessary to
correct any information on the Disclosure Schedule which has been rendered
inaccurate thereby. No supplement or amendment to the Disclosure Schedules nor
any investigation by the Company or the Buyer, before or after execution of this
Agreement, shall have any effect for the purpose of determining satisfaction of
the conditions set forth in Section 8.2 and Section 8.3, respectively, hereof or
compliance by the Buyer or the Company with the covenants set forth in Articles
VI and VII hereof.

         Section 7.11  Indemnification.

                  (a) From and after the Effective Time through the one-year
anniversary of the Effective Time, Buyer shall indemnify and hold harmless each
present and former director, officer and employee of the Company determined as
of the Effective Time (the "Indemnified Parties") against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages or liabilities (collectively, "Costs") incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time to the extent covered by directors and officers
insurance maintained by the Company (collectively, "Claims"), to the fullest
extent to which such Indemnified Parties would be entitled under New York law
and the Certificate of Incorporation and By-laws of the Company as in effect on
the date hereof.

                  Any Indemnified Party wishing to claim indemnification under
this Section 7.11(a), upon learning of any such claim, action, suit, proceeding
or investigation, shall promptly notify Buyer, but the failure to so notify
shall not relieve Buyer of any liability it may have to such Indemnified Party
if such failure does not materially prejudice Buyer. In the event of any such
claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), (i) Buyer shall have the right to assume the defense
thereof and Buyer shall not be liable to such Indemnified Parties for any legal
expenses of other counsel or any other expenses subsequently incurred by such
Indemnified Parties in connection with the defense thereof, except that if the
Buyer elects not to assume such defense or counsel for the Indemnified Parties
advises that there are issues which raise conflicts of interest between Buyer
and the Indemnified Parties, the Indemnified Parties may retain counsel which is
reasonably satisfactory to Buyer and Buyer shall pay, promptly as statements
therefore are received, the reasonable fees and expenses of such counsel for the
Indemnified Parties (which may not exceed one firm in any jurisdiction unless
the use of one counsel of such Indemnified Parties would present such counsel
with a conflict of interest), (ii) the Indemnified Parties will cooperate in the
defense of any such matter, and (iii) Buyer shall not be liable for any
settlement effected without its prior written consent, which consent shall not
be unreasonably withheld.

                  In the event that Buyer or any of its respective successors or
assigns (i) consolidates with or merges into any other Person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any Person, then, and in each such case, the successors and assigns of such
entity shall assume the obligations set forth in this Section 7.11, which
obligations

                                       22


are expressly intended to be for the irrevocable benefit of, and shall be
enforceable by, each of the Indemnified Parties.

                  (b) From and after the Effective Time, Buyer shall maintain a
directors' and officers' liability insurance policy covering the Indemnified
Parties Costs in connection with any Claims for a period of not less than one
(1) years after the Effective Time at annual premiums no greater than 150% of
the annual premium of the directors' and officers' liability insurance
maintained by the Company as of the date hereof.

         Section 9.1 Termination. This Agreement may be terminated at any time
prior to the Effective Time, whether before or after approval by the
Shareholders:

                  (a) by mutual written consent of Buyer and the Company;

                  (b) by the Company, upon a material breach of this Agreement
on the part of Buyer or Merger Subsidiary which has not been cured within 30
days of written notice of such breach and which would have a Material Adverse
Effect on the Company or would materially impair the parties' abilities to
consummate the transactions contemplated hereby;

                                       24



                  (c) by Buyer, upon a material breach of this Agreement on the
part of the Company which has not been cured within 30 days of written notice of
such breach and which would have a Material Adverse Effect on the Buyer or would
materially impair the parties' abilities to consummate the transaction
contemplated hereby;

                  (d) by Buyer or the Company if any court of competent
jurisdiction shall have issued, enacted, entered, promulgated or enforced any

decree, injunction or ruling shall have become final and nonappealable;

                  (e) by either Buyer or the Company if the Merger shall not

the Regulatory Authority which must grant such regulatory approval, unless
within the 45-day period following such denial or withdrawal a petition for
rehearing or an amended Application has been filed with the applicable
Regulatory Authority, provided, however, that no party shall have the right to
terminate this Agreement pursuant to this Section 9.1(f) if such denial or
request or recommendation for withdrawal shall be due to the failure of the
party seeking to terminate this Agreement to perform or observe the covenants
and agreements of such party set forth herein;

                  (g) by the Company if it receives a Superior Proposal and the
Company's Board of Directors determines that it would be in accordance with
their fiduciary duties, based upon the advice of its outside legal counsel, to
accept the third party proposal; provided, however, that in such event the
Company shall not be permitted to terminate this Agreement pursuant to this
Section 9.1(g) unless it has complied with the provisions of Section 7.7; or

                  (h) by the Buyer by written notice to the Company delivered in

on the part of any of the Company, Buyer or Merger Subsidiary or their
respective officers or directors; provided that Sections 9.2, 9.3, the
penultimate sentence of Section 7.1(b) and the provisions of Article 10 (other
than Section 10.3) shall survive such termination.

Agreement shall be paid by the party incurring such expenses.

                  (b) In the event of a willful breach of any representation,
warranty, covenant or agreement contained in this Agreement, the breaching party

reasonable attorneys' fees, sustained or incurred by the non-breaching party as
a result thereof or in connection therewith or with the enforcement of its
rights hereunder.

                  (c) In order to induce Buyer and Merger Subsidiary to enter
into this Agreement and to reimburse Buyer and Merger Subsidiary for their costs
and expenses in connection with this Agreement and the transactions contemplated
hereby, the Company shall pay to Buyer $75,000 cash, in the event that this
Agreement is terminated by the Company pursuant to Section 9.1(g).

         Section 9.4 Amendment. This Agreement may be amended by the parties
hereto at any time before or after approval hereof by the Shareholders, but,
after such approval, no amendment shall be made which (i) changes the form or
decreases the amount of the Merger Consideration, (ii) in any way materially
adversely affects the rights of the Shareholders or (iii) under applicable law
would require approval of the Shareholders without such approval having been
obtained. This Agreement may not be amended except by an instrument in writing
signed on behalf of each of the parties hereto.

         Section 9.5 Waiver. At any time prior to the Effective Time, the
parties hereto may, to the extent permitted by applicable law, (i) extend the
time for the performance of any of the obligations or other acts of any other
party hereto, (ii) waive any inaccuracies in the representations and warranties
by any other party contained herein or in any documents delivered by any other
party pursuant hereto and (iii) waive compliance with any of the agreements of

            EXHIBIT B - DISSENTERS RIGHTS UNDER NEW YORK BANKING LAW

ss.6022. Procedure to enforce stockholder's right to receive payment for shares.


1. A stockholder intending to enforce his right under a section of this chapter
to receive payment for his shares if the proposed corporate action referred to
therein is taken shall file with the corporation, before the meeting of
stockholders at which the action is submitted to a vote, or at such meeting but
before the vote, written objection to the action. The objection shall include a
statement that he intends to demand payment for his shares if the action is
taken. Such objection is not required from any stockholder to whom the
corporation did not give notice of such meeting in accordance with this chapter
or where the proposed action is authorized by written consent of stockholders
without a meeting.

2. Within ten (10) days after the stockholders' authorization date, which term
as used in this section means the date on which the stockholders' vote
authorizing such action was taken, or the date on which such consent without a
meeting was obtained from the requisite stockholders, the corporation shall give
written notice of such authorization or consent by registered mail to each
stockholder who filed written objection or from whom written objection was not
required, excepting any who voted for or consented in writing to the proposed
action.

3. Within twenty (20) days after the giving of notice to him, any stockholder to
whom the corporation was required to give such notice and who elects to dissent
shall file with the corporation a written notice of such election, stating his
name and residence address, the number and classes of shares as to which he
dissents and a demand for payment of the fair value of his shares.

4. A stockholder may not dissent as to less than all of the shares, held by him
of record, that he owns beneficially. A nominee or fiduciary may not dissent on
behalf of any beneficial owner as to less than all of the shares of such owner
held of record by such nominee or fiduciary.

5. Upon filing a notice of election to dissent, the stockholder shall cease to
have any of the rights of a stockholder except the right to be paid the fair
value of his shares and any other rights under this section. Withdrawal of a
notice of election shall require the written consent of the corporation. If a
notice of election is withdrawn, or the proposed corporate action is abandoned
or rescinded, or a court shall determine that the stockholder is not entitled to
receive payment for his shares, or the stockholder shall otherwise lose his
dissenter's rights, he shall not have the right to receive payment for his
shares and he shall be reinstated to all his rights as a stockholder as of the
filing of his notice of election, including any intervening preemptive rights
and the right to payment of any intervening dividend or other distribution or,
if any such rights have expired or any such dividend or distribution other than
in cash has been completed, in lieu thereof, at the election of the corporation,
the fair value thereof in cash as determined by the board as of the time of such
expiration or completion, but without prejudice otherwise to any corporate
proceedings that may have been taken in the interim.

6. At the time of filing the notice of election to dissent or within one month
thereafter the stockholder shall submit the certificates representing his shares
to the corporation, or to its transfer agent, which shall forthwith note
conspicuously thereon that a notice of election has been filed and shall return
the certificates to the stockholder or other person who submitted them on his
behalf. Any stockholder who fails to submit his certificates for such notation
as herein specified shall, at the option of the corporation exercised by written
notice to him within forty-five days from the date of filing of such notice of
election to dissent, lose his dissenter's rights unless a court, for good cause
shown, shall otherwise direct. Upon transfer of a certificate bearing such
notation, each new certificate issued therefor shall bear a similar notation
together with the name of the original dissenting holder of the shares and a
transferee shall acquire no rights in the corporation except those which the
original dissenting stockholder had after filing his notice of election.

7. Within seven days after the expiration of the period within which
stockholders may file their notices of election to dissent, or within seven days
after the proposed corporate action is consummated, whichever is later, the
corporation or, in the case of a merger, the receiving corporation, shall make a
written offer by registered mail to each stockholder who has filed such notice
of election to pay for his shares at a specified price which the corporation
considers to be their fair value. Such offer shall be made at the same price per
share to all dissenting stockholders of the same class, or if divided into
series, of the name series and shall be accompanied by a balance sheet of the




corporation whose shares the dissenting stockholder holds as of the latest
available date, which shall not be earlier than twelve months before the making
of such offer, and a profit and loss statement or statements for not less than a
twelve month period ended on the date of such balance sheet or, if the
corporation was not in existence throughout such twelve month period, for the
portion thereof during which it was in existence. If within thirty days after
the making of such offer, the corporation making the offer and any stockholder
agree upon the price to be paid for his shares, payment therefor shall be made
within sixty days after the making of such offer upon the surrender of the
certificates representing such shares.

8. The following procedure shall apply if the corporation fails to make such
offer within such period of seven (7) days, or if it makes the offer and any
dissenting stockholder or stockholders fail to agree with it within the period
of thirty days thereafter upon the price to be paid for their shares:

             (a)  The corporation or, in the case of a merger, the receiving
                  corporation shall, within twenty days after the expiration of
                  whichever is applicable of the two periods last mentioned,
                  institute a special proceeding in the supreme court in the
                  judicial district in which the office of the corporation is
                  located to determine the rights of dissenting stockholders and
                  to fix the fair value of their shares.

             (b)  If the corporation fails to institute such proceeding within
                  such period of twenty days, any dissenting stockholder may
                  institute such proceeding for the same purpose not later than
                  thirty days after the expiration of such twenty day period. If
                  such proceeding is not instituted within such thirty day
                  period, all dissenter's rights shall be lost unless the
                  supreme court, for good cause shown, shall otherwise direct.

             (c)  All dissenting stockholders, excepting those who, as provided
                  in subdivision seven, have agreed with the corporation upon
                  the price to be paid for their shares, shall be made parties
                  to such proceeding, which shall have the effect of an action
                  quasi in rem against their shares. The corporation shall serve
                  a copy of the petition in such proceeding upon each dissenting
                  stockholder who is a resident of this state in the manner
                  provided by law for the service of a summons, and upon each
                  nonresident dissenting stockholder either by registered mail
                  and publication, or in such other manner as is permitted by
                  law. The jurisdiction of the court shall be plenary and
                  exclusive.

             (d)  The court shall determine whether each dissenting stockholder,
                  as to whom the corporation requests the court to make such
                  determination, is entitled to receive payment for his shares.
                  If the corporation does not request any such determination or
                  if the court finds that any dissenting stockholder is so
                  entitled, it shall proceed to fix the value of the shares,
                  which, for the purposes of this section, shall be the fair
                  value as of the close of business on the day prior to the
                  stockholders' authorization date, excluding any appreciation
                  or depreciation directly or indirectly induced by such
                  corporate action or its proposal. The court may, if it so
                  elects, appoint an appraiser to receive evidence and recommend
                  a decision on the question of fair value. Such appraiser shall
                  have the power, authority and duties specified in the order
                  appointing him, or any amendment thereof.

             (e)  The final order in the proceeding shall be entered against the
                  corporation in favor of each dissenting stockholder who is a
                  party to the proceeding and is entitled thereto for the value
                  of his shares so determined.

             (f)  The final order shall include an allowance for interest at
                  such rate as the court finds to be equitable, from the
                  stockholders' authorization date to the date of payment. If
                  the court finds that the refusal of any stockholder to accept
                  the corporate offer of payment for his shares was arbitrary,
                  vexatious or otherwise not in good faith, no interest shall be
                  allowed to him.

             (g)  The costs and expenses of such proceeding shall be determined
                  by the court and shall be assessed against the corporation,
                  or, in the case of a merger, the receiving corporation, except
                  that all or any part of such costs and expenses may be
                  apportioned and assessed, as the court may determine, against
                  any or all of the dissenting stockholders who are parties to
                  the proceeding if the court finds that their refusal to accept
                  the corporate offer was arbitrary, vexatious or otherwise not
                  in good faith. Such expenses shall include reasonable
                  compensation for and the reasonable expenses of the

                                       2


                  appraiser, but shall exclude the fees and expenses of counsel
                  for and experts employed by any party unless the court, in its
                  discretion, awards such fees and expenses. In exercising such
                  discretion, the court shall consider any of the following: (A)
                  that the fair value of the shares as determined materially
                  exceeds the amount which such corporation offered to pay; (B)
                  that no offer was made by such corporation; and (C) that such
                  corporation failed to institute the special proceeding within
                  the period specified therefor.

             (h)  Within sixty (60) days after final determination of the
                  proceeding, the corporation or, in the case of a merger, the
                  receiving corporation shall pay to each dissenting stockholder
                  the amount found to be due him, upon surrender of the
                  certificates representing his shares.

9. Shares acquired by the corporation upon the payment of the agreed value
therefor or of the amount due under the final order, as provided in this
section, shall be dealt with as provided in section five thousand fourteen,
except that, in the case of a merger, they shall be disposed of as provided in
the plan of merger or consolidation.

10. The enforcement by a stockholder of his right to receive payment for his
shares in the manner provided herein shall exclude the enforcement by such
stockholder of any other right to which he might otherwise be entitled by virtue
of share ownership, except as provided in subdivision five, and except that this
section shall not exclude the right of such stockholder to bring or maintain an
appropriate action to obtain relief on the ground that such corporate action
will be or is illegal or fraudulent as to him.

11. Except as otherwise expressly provided in this section, any notice to be
given by a corporation to a stockholder under this section shall be given in the
manner provided in section six thousand five.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

         Under Sections 721 through 725 of the Business Corporation Law of the
State of New York (the "BCL"), the Registrant has broad powers to indemnify its
directors, officers and other employees. These sections (i) provide that the
statutory indemnification and advancement of expenses provision of the BCL are
not exclusive, provided that no indemnification may be made to or on behalf of
any director or officer if a judgment or other final adjudication adverse to the
director or officer establishes that his acts were committed in bad faith or
were the result of active and deliberate dishonesty and were material to the
cause of action os adjudicated, or that he personally gained in fact a financial
profit or other advantage to which he was not legally entitled, (ii) establish
procedures for indemnification and advancement of expenses that may be contained
in the certificate of incorporation or by-laws, or, when authorized by either of
the foregoing, set forth in a resolution of the shareholders or directors of an
agreement providing for indemnification and advancement of expenses, (iii) apply
a single standard for statutory indemnification for third-party and derivative
suits by providing that indemnification is available if the director or officer
acted in good faith, for a purpose which he reasonably believed to be in the
best interests of the corporation, and, in criminal actions, had no reasonable
cause to believe that his conduct was unlawful and (iv) permit the advancement
of litigation expenses upon receipt of an undertaking to repay such advance if
the director or officer is ultimately determined not to be entitled to
indemnification or to the extent the expenses advanced exceed the
indemnification to which the director or officer is entitled. Section 726 of the
BCL permits the purchase of insurance to indemnify a corporation or its officers
and directors to the extent permitted.

         As permitted by Section 721 of the BCL, the Registrant's By-laws
provide that the Registrant shall indemnify its officers and directors, as such,
to the fullest extent permitted by applicable law, and that expenses reasonably
incurred by any such officer or director in connection with a threatened or
actual action or proceeding shall be advanced or promptly reimbursed by the
Registrant in advance of the final disposition of such action or proceeding upon
receipt of an undertaking by or on behalf of such officer or director to repay
such amount if and to the extent that it is ultimately determined that such
officer or director is not entitled to indemnification.

         Article EIGHTH of the Registrant's Certificate of Incorporation
provides that no director of the Registrant shall be held personally liable to
the Registrant or its shareholders for damages for any breach of duty in his
capacity as a director occurring after authorization of such Article EIGHTH by
the shareholders unless a judgment or other final adjudication adverse to him
establishes that (1) his acts or omissions were in bad faith or involved
intentional misconduct or a knowing violation of law, or (2) he personally
gained in fact a financial profit or other advantage to which he was not legally
entitled, or (3) his acts violated section 719 of the BCL. The Registrant has
entered into Indemnity Agreements with its directors and certain key officers
pursuant to which the Registrant generally is obligated to indemnify its
directors and such officers to the full extent permitted by the BCL as described
above. The Company also has purchased directors' and officers' liability
insurance.

ITEM 22. UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

                  (i) To include any prospectus required by section 10(a)(3) of
         the Securities Act of 1933, as amended (the "Securities Act");

                                      II-2


                  (ii) To reflect in the prospectus any facts or events arising
         after the effective date of the Registration Statement (or the most
         recent post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the Registration Statement. Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20% change in the
         maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective Registration Statement;

                  (iii) To include any material information with respect to the
         plan of distribution not previously disclosed in the Registration
         Statement or any material change to such information in the
         Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by the registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The registrant hereby further undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         The registrant hereby further undertakes to deliver or cause to be
delivered with the Prospectus, to each person to whom the Prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the Prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X are not set forth in the Prospectus, to deliver, or cause to be
delivered to each person to whom the Prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
Prospectus to provide such interim financial information.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

         The registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the Prospectus pursuant to Items 4,
10(b), 11 or 13 of this Form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes

                                      II-3


information contained in documents filed subsequent to the effective date of the
Registration Statement through the date of responding to the request.

         The registrant hereby further undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.


                                      II-4


                                   SIGNATURES




Pursuant to the requirements of Section 13 or 15(d) of the Securities Act of
1933, the Registrant has duly caused this registration statement to be signed on
its behalf by the undersigned, thereunto duly authorized in the City of Warsaw,
State of New York on March 11, 2002.
