                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders
Community Bank System, Inc.
Dewitt, New York

     In our opinion, based on our audits and the report of other auditors, the
accompanying consolidated balance sheets and the related consolidated statements
of income, changes in shareholders' equity and of cash flows present fairly, in
all material respects, the financial position of Community Bank System, Inc. and
its subsidiaries at December 31, 2000 and 1999, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 2000 in conformity with accounting principles generally accepted in
the United States of America. These financial statements are the responsibility
of the Company's management; our responsibility is to express an opinion on
these financial statements based on our audits. We did not audit the financial
statements of First Liberty Bank Corp., a wholly owned subsidiary, which
statements reflect total assets of $627,873,000 and $653,275,000 as of December
31, 2000 and 1999, respectively, and net interest income of $19,087,000,
$20,016,000 and $19,692,000 for each of the three years in the period ended
December 31, 2000. Those statements were audited by other auditors whose report
thereon has been furnished to us, and our opinion expressed herein, insofar as
it relates to the amounts included for First Liberty Bank Corp., is based solely
on the report of the other auditors. We conducted our audits of these statements
in accordance with auditing standards generally accepted in the United States of
America, which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits and the report of other auditors provide a reasonable basis for our
opinion.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors
First Liberty Bank Corp.:

     We have audited the consolidated balance sheets of First Liberty Bank Corp.
and subsidiaries (the "Company") as of December 31, 2000 and 1999, and the
related consolidated statements of operations, changes in shareholders' equity,
and cash flows for each of the years in the three year period ended December 31,
2000 (not included herein). Those consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on those consolidated financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of First
Liberty Bank Corp. and subsidiaries as of December 31, 2000 and 1999, and the
results of their operations and their cash flows for each of the years in the
three year period ended December 31, 2000, in conformity with accounting
principles generally accepted in the United States of America.

NOTE A: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Business Combination

     On May 11, 2001, Community Bank System, Inc. (the "Company") completed its
acquisition of First Liberty Bank Corp. ("First Liberty"). Pursuant to the terms
of the merger, each share of First Liberty stock was exchanged for .56 shares of
the Company's common stock, which amounted to approximately 3.6 million shares.
The merger constituted a tax-free reorganization and has been accounted for as a
pooling of interests under Accounting Principles Board Opinion No. 16.
Accordingly, the consolidated financial statements for the periods presented
have been restated to include the combined results of operations, financial
position and cash flows of the Company and First Liberty. Certain
reclassifications were made to First Liberty's prior year financial statements
to conform to the Company's presentation.

     Results of operations for the separate companies and the combined amounts
presented in the consolidated financial statements follow:

           (IN THOUSANDS OF DOLLARS, EXCEPT PER SHARE AND SHARE DATA)

  Use of Estimates in the Preparation of Financial Statements

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

  Risk and Uncertainties

     In the normal course of its business, the Company encounters economic and
regulatory risks. There are three main components of economic risk: interest
rate risk, credit risk and market risk. The Company is subject to interest rate
risk to the degree that its interest-bearing liabilities mature or reprice at
different speeds, or on different bases from its interest-earning assets. The
Company's primary credit risk is the risk of default on the Company's loan
portfolio that results from the borrowers' inability or unwillingness to make
contractually required payments. Market risk reflects potential changes in the
value of collateral underlying loans, the fair value of investment securities
and loans held for sale.

     The Company is subject to the regulations of various government agencies.
These regulations can and do change significantly from period to period. The
Company also undergoes periodic examinations by the regulatory agencies which
may subject it to further changes with respect to asset valuations, amounts of
required loss allowances, and operating restrictions resulting from the
regulators' judgments based on information available to them at the time of
their examinations.

  Cash and Cash Equivalents

     For purposes of reporting cash flows, cash and cash equivalents include
cash on hand, amounts due from banks and federal funds sold. Generally, federal
funds are sold for one-day periods. The carrying amounts reported in the balance
sheet for cash and cash equivalents approximate those assets' fair values.

  Investment Securities

     The Company has classified its investments in debt and equity securities as
held-to-maturity or available-for-sale. Held-to-maturity securities are those
for which the Company has the positive intent and ability to hold to maturity,
and are reported at cost, which is adjusted for amortization of premiums and
accretion of discounts. Debt securities not classified as held to maturity are
classified as available-for-sale and are reported at fair market value with net
unrealized gains and losses reflected as a separate component of shareholders'
equity, net of applicable income taxes. None of the Company's investment
securities have been classified as trading securities. Equity securities are
stated at cost and include stock of the Federal Reserve Bank of New York and
Federal Home Loan Bank of New York.

     The average cost method is used in determining the realized gains and
losses on sales of investment securities, which are reported under other income
as investment security gains (losses). Premiums and discounts on securities are
amortized and accreted, respectively, on a systematic basis over the period to
maturity, estimated life, or earliest call date of the related security.

     Fair values for investment securities are based on quoted market prices,
where available. If quoted market prices are not available, fair values are
based on quoted market prices of comparable instruments.

                  COMMUNITY BANK SYSTEM, INC. AND SUBSIDIARIES

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
           (IN THOUSANDS OF DOLLARS, EXCEPT PER SHARE AND SHARE DATA)

  Loans

     Loans are stated at unpaid principal balances. Fair values for variable
rate loans that reprice frequently, with no significant credit risk, are based
on carrying values. Fair values for fixed rate loans are estimated using
discounted cash flows and interest rates currently being offered for loans with
similar terms to borrowers of similar credit quality. Mortgage loans held for
sale are carried at the lower of cost or market and are included in loans as the
balance of such loans was not significant. The carrying amount of accrued
interest approximates its fair value.

  Interest on Loans and Reserve for Loan Losses

     Interest on commercial loans and mortgages is accrued and credited to
operations based upon the principal amount outstanding. Unearned discount on
installment loans is recognized as income over the term of the loan, principally
by the actuarial method. Non-refundable loan fees and related direct costs are
deferred and amortized over the life of the loan as an adjustment to loan yield
using the effective interest method.

     The Bank places a loan on nonaccrual status and recognizes income on a cash
basis when it is more than ninety days past due (or sooner, if management
concludes collection of interest is doubtful), except when, in the opinion of
management, it is well-collateralized and in the process of collection.

     The reserve for loan losses reflects management's best estimate of probable
loan losses in the Company's loan portfolio, considering evaluations of
individual credits and concentrations of credit risk, changes in the quality of
the credit portfolio, levels of nonaccrual loans, current economic conditions,
changes in the size and character of the credit risks and other pertinent
factors. The reserve is increased by provisions charged to expense and reduced
by net charge-offs. A loan is considered impaired, based on current information
and events, if it is probable that the Bank will not be able to collect the
scheduled payments of principal or interest when due according to the
contractual terms of the loan agreement. The measurement of impaired loans is
generally based on the present value of expected future cash flows discounted at
the historical effective interest rate, except that all collateral-dependent
loans are measured for impairment based on the fair value of the collateral.

  Premises and Equipment

     Premises and equipment are stated at cost less accumulated depreciation.
The annual provision for depreciation is computed using the straight-line method
in amounts sufficient to recognize the cost of depreciable assets over their
estimated useful lives. Maintenance and repairs are charged to expense as
incurred.

  Other Real Estate

     Properties acquired through foreclosure, or by deed in lieu of foreclosure,
are carried at the lower of the unpaid loan balance plus settlement costs, or
fair value less estimated costs of disposal. At December 31, 2000 and 1999,
other real estate, included in other assets, amounted to $1,293 and $1,442,
respectively.

  Intangible Assets

     Intangible assets represent principally core deposit value and goodwill
arising from acquisitions. The Company periodically reviews the carrying value
of intangible assets using fair value methodologies. Core deposit intangibles
are being amortized principally on an accelerated basis over ten years and
goodwill is being amortized on a straight-line basis over 15 to 25 years.

           (IN THOUSANDS OF DOLLARS, EXCEPT PER SHARE AND SHARE DATA)

  Mortgage Servicing Rights

     Originated mortgage servicing rights are recorded at their fair value at
the time of transfer and are amortized in proportion to and over the period of
estimated net servicing income or loss. The Bank uses a valuation model that
calculates the present value of future cash flows to determine the fair value of
servicing rights. In using this valuation method, the Bank incorporated
assumptions that market participants would use in estimating future net
servicing income, which included estimates of the cost of servicing per loan,
the discount rate, and prepayment speeds. The carrying value of the originated
mortgage servicing rights is periodically evaluated for impairment using these
same market assumptions. At December 31, 2000 and 1999, mortgage servicing
rights, included in other assets, amounted to approximately $526 and $577,
respectively.

  Deposits

     The fair values disclosed for demand and savings deposits are equal to the
carrying amounts at the reporting date. The carrying amounts for variable rate
money market accounts and certificates of deposit approximate their fair values
at the reporting date. Fair values for fixed rate certificates of deposit are
estimated using discounted cash flows and interest rates currently being offered
on similar certificates. The carrying value of accrued interest approximates
fair value.

  Borrowings

     The carrying amounts of federal funds purchased and short-term borrowings
approximate their fair values. Fair values for long-term borrowings are
estimated using discounted cash flows at interest rates currently being offered
on similar borrowings.

  Income Taxes

     Provisions for income taxes are based on taxes currently payable or
refundable, and deferred taxes which are based on temporary differences between
the tax basis of assets and liabilities and their reported amounts in the
financial statements. Deferred tax assets and liabilities are reported in the
financial statements at currently enacted income tax rates applicable to the
period in which the deferred tax assets and liabilities are expected to be
realized or settled.

  Trust Department Assets

     Assets held in fiduciary or agency capacities for customers are not
included in the accompanying consolidated statements of condition, since such
items are not assets of the Company. Fees associated with providing trust
management services are recorded on cash basis of income recognition and are
included in other income.

  Earnings Per Share

     Basic earnings per share are computed on the basis of actual weighted
average common shares outstanding for the period. Diluted earnings per share
reflect the dilutive effect of outstanding common stock equivalents.

  Treasury Stock

     Treasury stock purchases are recorded at cost. During 2000 and 1999, the
Company purchased 100,000 and 221,500 shares of treasury stock at an average
cost of $22.88 and $25.13, respectively. The Company purchases treasury stock
primarily in order to have shares available for issuance under the incentive
stock option, restricted stock awards and non-qualified stock option plan and
for other strategic purposes.

           (IN THOUSANDS OF DOLLARS, EXCEPT PER SHARE AND SHARE DATA)

  Fair Values of Financial Instruments

     The Company determines fair values based on quoted market values where
available or on estimates using present values or other valuation techniques.
Those techniques are significantly affected by the assumptions used, including
the discount rate and estimates of future cash flows. In that regard, the
derived fair value estimates cannot be substantiated by comparison to
independent markets and, in many cases, could not be realized in immediate
settlement of the instrument. Statement Financial Accounting Standard No. 107,
"Disclosures about Fair Value of Financial Instruments," excludes certain
financial instruments and all nonfinancial instruments from its disclosure
requirements. Accordingly, the aggregate fair value amounts presented do not
represent the underlying value of the Company.

     The fair values of investment securities, loans, deposits, and borrowings
have been disclosed in footnotes C, D, G, and H, respectively.

  Accounting Pronouncements

     In 1998, the Company adopted SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement requires an entity to
recognize all derivatives as either assets or liabilities in the balance sheet
and measure those instruments at fair value. Upon adoption of the SFAS, the
Company transferred investment securities from held-to-maturity to
available-for-sale (see Note C). As a result, securities previously classified
as held-to-maturity were sold during the year and investment securities gains of
approximately $194,000, net of tax, resulting from the sale have been reported
as a cumulative effect of a change in accounting principle. The Company has no
outstanding derivative financial instruments and, accordingly, adoption of SFAS
133 had no other affect on the Company's financial statements.

  Subsequent Event

     On January 26, 2001, the Company acquired Citizens National Bank of Malone,
an eighty-year-old commercial bank with five branches throughout Franklin and
St. Lawrence counties in New York State. The Company issued 952,000 shares of
its common stock to the former shareholders at a cost of $26.50 per share. All
of the 648,100 shares held in the Company's treasury were issued in this
transaction. The acquisition is being accounted for under the purchase method of
accounting. The Company purchased assets with a fair value of $110,137, assumed
liabilities with a fair value of $98,681 and recorded other purchase accounting
adjustments of $499. The resulting goodwill of $13,273 will be amortized over a
fifteen year period.

NOTE B: ACQUISITION

  Elias Asset Management, Inc.

     On April 3, 2000, Community Bank System, Inc. acquired all the stock of
Elias Asset Management, Inc. (EAM) for cash of $6.5 million. EAM, based in
Williamsville, NY, is a nationally recognized firm with $650 million in assets
under management for individuals, corporate pension and profit sharing plans,
and foundations. In accordance with the stock purchase agreement, additional
consideration will be paid if certain performance targets are met over a
five-year period. This transaction was accounted for under the purchase method,
and the Company recognized $6.1 million of goodwill, which is being amortized
over 20 years.

     The Company has determined that no valuation allowance is necessary as it
is more likely than not that deferred tax assets will be realized through
carryback of future deductions to taxable income in prior years, future
reversals of existing temporary differences, and through future taxable income.

NOTE J: LIMITS ON DIVIDENDS AND OTHER REVENUE SOURCES

     The Company's ability to pay dividends to its shareholders is largely
dependent on the Bank's ability to pay dividends to the Company. In additional
to state law requirements and the capital requirements discussed below, the
circumstances under which the Bank may pay dividends are limited by federal
statutes, regulations, and policies. For example, as a national bank, the Bank
must obtain the approval of the Office of the Comptroller of the Currency (OCC)
for payments of dividends if the total of all dividends declared in any calendar
year would exceed the total of the Bank's net profits, as defined by applicable
regulations, for that year, combined with its retained net profits for the
preceding two years. Furthermore, the Bank may not pay a dividend in an amount
greater than its undivided profits then on hand after deducting its losses and
bad debts, as defined by applicable regulations. At December 31, 2000, the Bank
had approximately $26,983 in undivided profits legally available for the
payments of dividends.

     In addition, the Federal Reserve Board and the OCC are authorized to
determine under certain circumstances that the payment of dividends would be an
unsafe or unsound practice and to prohibit payment of such dividends. The
Federal Reserve Board has indicated that banking organizations should generally
pay dividends only out of current operating earnings.

     There are also statutory limits on the transfer of funds to the Company by
its banking subsidiary, whether in the form of loans or other extensions of
credit, investments or assets purchases. Such transfer by the Bank to the
Company generally are limited in amount to 10% of the Bank's capital and
surplus, or 20% in the aggregate. Furthermore, such loans and extensions of
credit are required to be collateralized in specific amounts.

NOTE K: BENEFIT PLANS

     The Company has noncontributory defined benefit pension plans covering the
majority of its employees and retirees. The Company also provides health and
life insurance benefits for eligible retired employees and dependents.

     The defined benefit pension plan maintained by Community Bank is authorized
to invest up to 10% of the fair value of its total assets in common stock of
Community Bank System, Inc. At December 31, 2000 and 1999, the plan holds 46,500
and 43,378 shares, respectively, of the sponsor Company common stock.

     Health care cost assumptions have no effect on the amounts reported for the
health care plans, since the plan changed to a fixed dollar employee
contribution plan in 1999.

     The Company also has an Employee Savings and Retirement Plan, which is
administered by the Trust Department of Community Bank, N. A. The Employee
Savings and Retirement Plan includes Section 401(k) and Thrift provisions as
defined under the Internal Revenue Code. Company contributions to the trust
amounted to $838, $830, and $848 in 2000, 1999, and 1998, respectively.

     The Company has deferred compensation agreements with its President and
Chief Executive Officer and several former executives and officers whereby
monthly payments are to be provided upon retirement over periods ranging from
ten to 25 years. Expense recognized during 2000, 1999, and 1998 related to these
arrangements amounted to approximately $328, $367, and $258, respectively. The
Company has recorded a liability of $1,985 and $1,713 at December 31, 2000 and
1999, respectively.

     The Company has a Stock Balance Plan for nonemployee directors who have
completed six months of service. The Plan is a nonqualified, noncontributory
defined benefit plan. The Plan provides benefits for periods of service prior to
January 1, 1996 based on a predetermined formula. Amounts credited to
participant accounts for all creditable service after January 1, 1996 are based
on performance of the Company's stock. Participants become fully vested after
six years of service. Benefits are payable in the form of stock of the Company
on the first of the month following the later of a participant's disassociation
from the Board or attainment of age 70. Unrecognized prior service cost of $435
at December 31, 2000 is being amortized over 8 years. Expense related to the
Plan recognized in 2000, 1999, and 1998, approximated $9, $20, and $19,
respectively. The accrued pension liability was approximately $349 and $367 at
December 31, 2000 and 1999, respectively. The net periodic pension cost was
calculated using discount rates of 7.0% in 2000 and 1999.

     The Company maintains for certain of its executive officers and directors
(participants), a Supplemental Plan which provides that the participants share
in the rights to the death benefits of a split-dollar life insurance policy and
provides for additional compensation to the participants, equal to any income
tax consequences related to the Supplemental Plan until retirement. To fund the
annual premium on the split-dollar policy and mitigate the obligations under
this Plan, the Company has purchased an additional bank owned life insurance
(BOLI) policy on the participants' lives. The amount of the BOLI policy has been
calculated so that the projected increases in its cash surrender value will
substantially offset the Company's expense related to the

split-dollar policy. At December 31, 2000, the Company had $4,678 in cash
surrender value of life insurance. The split-dollar policy is designed to
provide the participants, upon attaining retirement age, with projected annual
after-tax distributions. The amount of the benefit obligation for certain
participants is increased or decreased each year by an amount equal to the
annual BOLI policy earnings less the Company's cost of funds. At December 31,
2000, the recorded liability related to this portion of the Supplemental Plan is
$135. In addition, a separate benefit obligation for certain other participants
consist of deferred compensation increased by interest rates established in the
Supplemental Plan. These rates range from 11% to 12%. At December 31, 2000, the
accrued liability for these participants is $292. The expense for the
Supplemental Plan was $163, $75, and $44 for 2000, 1999, and 1998, respectively.

NOTE L: STOCK-BASED COMPENSATION PLANS

     The Company has long-term, stock-based incentive compensation programs for
directors, officers, and key employees, including incentive stock options
(ISO's), restricted stock awards (RSA's), nonqualified stock options (NQSO's),
warrants, retroactive stock appreciation rights, and discounted options. The
Company has authorized the grant of options for up to 1,139,336 shares of the
Company's common stock. All options granted have ten-year terms and vest and

     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation," provides for a fair-value-based method of accounting
for stock compensation plans with employees and others. Alternatively, the
statement allows that entities may continue to account for stock-based
compensation plans in accordance with Accounting Principles Board (APB) Opinion
No. 25, "Accounting for Stock Issued to Employees," with disclosure of pro forma
amounts reflecting the difference between cost charged to operations pursuant to
APB No. 25 and compensation cost that would have been charged to operations had
SFAS No. 123 been applied. The Company has elected to continue following APB No.

     The fair value of these options was estimated at the date of grant using a
Black-Scholes options pricing model with the following weighted average
assumptions for 2000, 1999 and 1998: risk-free interest rates by grant ranging
from 4.65% to 6.93% during 2000, 4.65% to 5.78% during 1999, and 5.55% to 5.67%
during 1998; dividend yields of 3.00% during 2000, 1999 and 1998; volatility
factors of the expected market price of the Company's common stock of 29.15% for
2000, 30.78% for 1999 and 44.06% for 1998; and a weighted-average expected life
of the option of 7.11 years in 2000, 6.70 for 1999, and 8.27 for 1998.

     For the purposes of proforma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. Therefore, the
preceding results are not likely to be representative of the effects on reported
net income for future years due to additional years of vesting.

     At December 31, 2000 the weighted average information for outstanding and
exercisable options is as follows:

participating director and credits to such account the number of shares of
Company common stock which would have been purchased with the director fees and
shares equal to the amount of dividends which

entitled to receive either shares of the Company common stock equal to the
number of shares accumulated or at the Company's election, cash equal to the
fair value of the number of shares accumulated. There were 25,539 and 19,614
shares credited to participant accounts at December 31, 2000 and 1999,
respectively, for which a liability of approximately $769 and $638 was accrued
and approximately $130 and $146 was recognized as expense.

NOTE M: EARNINGS PER SHARE

     Basic earnings per share are computed based on the weighted average shares
outstanding. Diluted earnings per share is computed based on the weighted
average shares outstanding adjusted for the dilutive effect of the assumed
exercise of stock options during the year. The following is a reconciliation of
basic to diluted earnings per share for the years ended December 31:

NOTE N: COMMITMENTS, CONTINGENT LIABILITIES AND RESTRICTIONS

     The Company is a party to financial instruments with off-balance-sheet risk
in the normal course of business to meet the financing needs of its customers.
These financial instruments consist primarily of commitments to extend credit,
which involve, to varying degrees, elements of credit risk in excess of the
amount recognized in the statement of condition. The contract amount of those
commitments to extend credit reflects the extent of involvement the Company has
in this particular class of financial instrument. The Company's exposure to
credit loss in the event of nonperformance by the other party to the financial
instrument for commitments to extend credit is represented by the contractual
amount of the instrument. The Company uses the same credit policies in making
commitments as it does for on-balance-sheet instruments.

</Table>

     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since some of the commitments are expected to
expire without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. The Company evaluated each customer's credit
worthiness on a case-by-case basis. The amount of collateral obtained, if deemed
necessary by the Company upon extension of credit, is based on management's
credit evaluation of the customer. Collateral held varies but may include
residential real estate, income-producing commercial properties, and personal
property. The Company has unused lines of credit totaling $3,900 and $6,000 at
December 31, 2000 and 1999, respectively. The Company has additional unused
borrowing capacity through collateralized transactions with the Federal Home
Loan Bank.

     The Company is required to maintain a reserve balance, as established by
the Federal Reserve Bank of New York. The required average total reserve for the
14-day maintenance period ended December 31, 2000 was $20,060, of which $2,000
was required to be on deposit with the Federal Reserve Bank of New York. The
remaining $18,060 was represented by cash on hand.

NOTE O: LEASES

     The Company leases buildings and office space under agreements that expire
in various years. Rental expense included in operating expenses amounted to
$1,014, $991 and $1,132 in 2000, 1999 and 1998, respectively.

     The future minimum rental commitments as of December 31, 2000 for all
noncancelable leases are as follows:

NOTE P: REGULATORY MATTERS

     The Bank is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory and possibly additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings, and other factors.

     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 2000 and December
31, 1999, that the Bank meets all capital adequacy requirements to which it is
subject and is "well capitalized" under the regulatory framework of prompt
corrective action. To be categorized as "well capitalized," the Bank must
maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios
as set forth in the following table.

     On February 3, 1997, the Company formed a subsidiary business trust,
Community Capital Trust I (Trust), for the purpose of issuing preferred
securities which qualify as Tier I capital (see Note P). Concurrent with its
formation, the Trust issued $30,000,000 of 9.75%-preferred securities in an
exempt offering. The preferred securities are non-voting, mandatorily redeemable
in 2027, and guaranteed by the Company. The entire net proceeds to the Trust
from the offering were invested in junior subordinated obligations of the
Company. The costs related to the issuance of these securities are capitalized
and amortized over the life of the period to redemption on a straight-line
basis.

     On February 21, 1995, the Company adopted a Stockholder Protection Rights
Agreement and declared a dividend of one right for each outstanding share of
common stock. The rights can only be exercised when an individual or group has
acquired or attempts to acquire 15% or more of the Company's common stock, if
such

action the Board of Directors believes is not in the best interest of the
stockholders. Each right then entitles the holder to acquire common stock having
a market value equivalent to two times the stated exercise price. The rights
expire in February 2005 and may be redeemed by the Company in whole at a price
of $.01 per right.

NOTE R: SUBSEQUENT EVENTS

     On June 8, 2001, the Company signed an agreement to acquire 36 branches,
with deposits of approximately $484,000 and loans of approximately $243,000,
from FleetBoston Financial. The transaction is subject to regulatory approval
and is scheduled to close in early fourth quarter 2001. The branches, which are
in the Southwestern and Finger Lakes regions of New York, will be merged into
the Company's branch network.

     On July 16, 2001, the Company formed a wholly-owned subsidiary, Community
Capital Trust II, a Delaware business trust. The trust issued $25,000 of 30 year
floating rate Company-obligated Capital Securities of Community Capital Trust II
Holding Solely Parent Debentures. The Company borrowed the proceeds of the
Capital Securities from its Subsidiary by issuing Deeply Subordinated Junior
Debentures having substantially similar terms. The Capital Securities mature in
year 2031 and are treated as Tier 1 capital by the Federal Reserve Bank of New
York. The Capital Securities are a pooled trust preferred fund of MM Community
Funding I, Ltd, and are tied to the six month LIBOR plus 3.75% with a five year
call provision. The current implied coupon yields 7.57%.

     On July 31, 2001, the Company a wholly-owned subsidiary, Community
Statutory Trust III, a Connecticut business trust. The trust issued $24,450 of
30 year floating rate Company-obligated pooled Capital Securities of Community
Statutory Trust III Holding Solely Parent Debentures. The Company borrowed the
proceeds of the Capital Securities from its Subsidiary by issuing Deeply
Subordinated Junior Debentures having substantially similar terms. The Capital
Securities mature in year 2031 and are treated as Tier 1 capital by the Federal
Reserve Bank of New York. The Capital Securities are a pooled trust preferred
fund of First Tennessee/KBW Pooled Trust Preferred Deal III, and are tied to the
three month LIBOR plus 3.75% with a five year call provision. The current
implied coupon yields 7.29%.

     In July 2001, the Financial Accounting Standards Board issued SFAS No. 142,
"Goodwill and Other Intangible Assets", which addresses financial accounting and
reporting for acquired goodwill and other intangible assets and supersedes APB
Opinion No. 17, "Intangible Assets". The statement will require, beginning
January 1, 2002, that the Company subject goodwill and other intangible assets
to an annual impairment analysis to assess the need to write down the balances
and recognize an impairment loss. In addition, amortization of certain
intangible assets will no longer be recorded upon adoption of this statement.
The Company expects that adoption of this pronouncement will reduce annual
amortization expense by approximately $4,300.
