business trust. The Trust has issued $30 million aggregate liquidation amount of
9.75% Company-Obligated Mandatorily Redeemable Preferred Securities representing
undivided beneficial interests in the assets of the Trust. The Company borrowed
the proceeds of the Preferred Securities from the Trust by issuing Junior
Subordinated Debentures to the Trust having substantially similar terms as the
Preferred Securities. The sole assets of the Trust on June 30, 2001 were
$32,011,763 aggregate principal amount of the Company's Junior Subordinated
Debentures, together with the related accrued interest receivable thereon. The
Preferred Securities mature in 2027, and are treated as Tier 1 capital by the
Federal Reserve Bank of New York. The guarantees issued by the Company for the
Trust, together with the Company's obligations under the Trust Agreement, the
Junior Subordinated Debentures and the Indenture under which the Junior
Subordinated Debentures were issued, constitute a full and unconditional
guarantee by the Company of the Preferred Securities issued by the Trust.

On April 3, 2000, Community Bank System, Inc. acquired all the stock of Elias
Asset Management, Inc. for cash of $6.5 million. In accordance with the stock
purchase agreement, additional consideration will be paid if certain revenue
targets are met over the next five years. This transaction was accounted for
under the purchase method.

On January 26, 2001, the Company acquired The Citizens National Bank of Malone,
an eighty-year-old commercial bank, in a transaction valued at $25,228,000.
952,000 shares of common stock of the Company were issued to the shareholders of
Citizens to effect the transaction. The Company purchased assets with a fair
value of $110,137,000, assumed liabilities with the fair value of $98,681,000
and recorded other purchase accounting adjustments totaling $499,000. The excess
of purchase price over fair value of assets acquired amounted to $13,273,000 and
will be amortized over a fifteen year period.

On May 11, 2001, the Company and First Liberty Bank Corp. ("First Liberty" or
"FLIB") completed their merger, approved by their respective shareholders on
April 23, 2001, in which the Company acquired all of the stock of FLIB and
merged First Liberty Bank & Trust, FLIB's principal subsidiary, into Community
Bank, N.A., the Company's banking subsidiary. First Liberty Bank & Trust will
continue to operate under its present name in Pennsylvania as a division of
Community Bank.

Pursuant to the definitive agreement, each share of common stock of FLIB was
exchanged on a tax-free basis for 0.56 shares of registered common stock of the
Company. At the closing price of the Company's common stock on May 11 of $27.80,
the shares of Company common stock received by FLIB shareholders have a value of
$99.1 million, or $15.57 per share. The Company issued approximately 3,566,000
shares of its common stock in the transaction, which has been recorded under the
pooling method of accounting.

NOTE B - SUBSEQUENT EVENTS

On June 8, 2001, the Company and its wholly-owned banking subsidiary, Community
Bank, signed an agreement to acquire 36 branches, with deposits of approximately
$484 million and loans of approximately $243 million, from FleetBoston Financial
(NYSE: FBF). 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 Community
Bank's branch network.

On July 16, 2001, Community Bank System, Inc. formed a wholly-owned subsidiary,
Community Capital Trust II, a Delaware business trust. The trust issued $25
million 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
yield is 7.58%.

On July 31, 2001, Community Bank System, Inc. formed a wholly-owned subsidiary,
Community Statutory Trust III, a Connecticut business trust. The trust issued
$24.450 million of 30 year floating rate Company-obligated 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 3.58% with a five year call provision. The
current implied coupon yield is 7.22%.

NOTE C - NEW ACCOUNTING PRONOUNCEMENTS

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 the adoption of this pronouncement will significantly reduce
amortization expense.

SUMMARY AND INTRODUCTION

Results for the three months ended June 30, 2001 include the effects of the
Company's May 11, 2001 merger with $647-million-asset First Liberty Bank Corp of
Jermyn, P.A. All historical information has been retroactively restated to
reflect this acquisition on a pooling-of-interest method of accounting. The
Company's January 26, 2001 acquisition of the $112-million-asset Citizens
National Bank of Malone (NY) was a purchase accounting transaction, and,
accordingly, there is no restatement of historical information.

Cash operating earnings for second quarter 2001 were $6.0 million, a decrease of
16% from the same period last year. This performance measure, which excludes
amortization expense as well as one-time acquisition costs and related
securities losses, is considered by Company management to be the best indicator
of recurring earnings and is consistent with the banking industry's growing
recognition of the importance of cash earnings. Cash operating earnings per
share (diluted) for the quarter were $0.51, down 23% from the prior year's level
of $0.66, reflective of greater shares outstanding due to the First Liberty
merger as well as the Citizens Bank acquisition. Compared to first quarter 2001,
cash operating earnings and cash operating earnings per share (diluted)
decreased 17% and 19%, respectively. For the first six months of 2001, cash
operating earnings were $13.1 million, down 8% from the comparable period in
2000, while cash operating earnings per share were $1.13, off 14% from the same
period prior year.

GAAP net income, including $4.8 million in one-time acquisition expenses and
related securities losses, was $2.1 million for second quarter 2001, a decrease
of $4.3 million or 67% from the same period last year. GAAP earnings per share
(diluted) for the quarter were $0.18, down $0.41 or 70%. For the first half of
2001, when one-time expenses totaled $5.6 million, GAAP net income was $7.9
million, off 39% from the prior year, while GAAP earnings per share (diluted)
were $0.68, off 43%.

SECOND QUARTER PERFORMANCE HIGHLIGHTS

o    Noninterest income (excluding securities transactions) for second quarter
     2001 exceeded the comparable quarter last year by 12%. Overdraft fees,
     reflective of a pricing increase during second quarter 2001 and the
     contribution of the Citizens Bank acquisition, accounted for over 41% of
     the increase. Financial services revenues generated approximately 27% of
     the improvement. The ratio of noninterest income to operating income rose
     1.3 percentage points to 21.0%. For the first half of the year, other
     income climbed over 19%, particularly reflective of the April 3, 2000
     purchase of Elias Asset Management (EAM). Compared to first quarter 2001,
     noninterest income rose 10.0%, marked by improved revenues from the
     Company's broker-dealer, Community Investment Services, Inc. (CISI) (up
     54%), and higher general banking fees (up 14%).

o    Net interest income for second quarter 2001 rose by 1.8% over the same
     period last year on 12.1% greater average earning assets. This reflects a
     35 basis-point-compression in net interest margin to 3.79%, primarily
     caused by loan and deposit pricing driven by the 275 and 173
     basis-point-decreases in the prime and one year Treasury rates,
     respectively, during the first half of this year. Because of the nature of
     the Company's balance sheet, earning asset yields have adjusted more
     quickly than the steady but slower rate decreases on consumer deposits
     outstanding. The 16 basis-point-gap between the reduction in yields and
     cost of funds in the second quarter compared to the first quarter is
     expected to narrow in future quarters.

o    Noninterest expense for the three months ended June 30, 2001, rose by $7.1
     million (40%) over the same period last year. One-time expenses related to
     the Citizens and First Liberty acquisitions totaled $4.6 million or 66% of
     the increase. The bulk of these latter expenses relate to consulting fees,
     severance, and write-down of obsolete software. Excluding one-time items
     and intangible amortization, noninterest expenses would have been $18.6
     million (up $2.1 million or 12.7% over the second quarter of 2000). Costs
     added by the five former Citizens branches were $440,000. Approximately
     half the benefit of a projected $3.2 million in annual cost reductions
     following the consummation of the First Liberty acquisition was reflected
     in the quarter. The balance of these savings is expected to be realized
     before year end. Besides readily identifiable acquisition expenses as
     defined above, there was a variety of miscellaneous start up costs and
     adjustments to accrued liabilities related to First Liberty, which are not
     expected in subsequent quarters. Included in those adjustments were
     additional second quarter taxes of approximately $236,000, which brought
     the year-to date effective tax rate to 30%, the rate expected for 2001 as a
     whole.

o    Despite the softening economy, loans at $1.57 billion decreased by $3.6
     million or .2% during the three months ended June 30, 2001. Real estate
     outstandings rose $4.4 million, largely due to continued success of
     Community Bank's "no-closing-cost" residential mortgage program. Commercial
     loans increased $800,000 during the same period compared to a $8.8 million
     reduction in installment loans. The latter reduction occurred because new
     business was inadequate to offset the high cash flow from maturing
     installment loans, which have relatively short lives. Over the last twelve
     months, total loans have risen approximately $72 million or 4.8%, including
     $59 million related to the Company's acquisition of Citizens Bank in
     January. Mortgage loans originated and sold in the secondary market were
     $13.1 million in the second quarter, up substantially from the first
     quarter 2001 activity of $4.4 million. The serviced loan portfolio stood at
     $101 million as of quarter end, up 12% from one year earlier.

o    Investments reached $1.054 billion at June 30, 2001, up over $164 million
     (18%) from one year earlier. This increase is a result of the Citizens Bank
     acquisition in January 2001 and planned securities leverage strategy in
     anticipation of the First Liberty transaction. Capital market borrowing
     increased approximately $42 million, with the bulk of the $236 million in
     earning asset growth over the last twelve months being funded by higher
     deposit levels.

o    Deposits at June 30, 2001 were $2.051 billion, an increase of $160 million
     (8.4%), compared to a year ago. On average, second quarter deposits rose
     9.8% ($186 million) over the same quarter last year. Deposits of
     individuals, partnerships, and corporations, which exclude the more
     volatile public funds deposits, rose 12.3% ($205 million); deposits from
     Citizens Bank account for $79 million of this increase. The primary reason
     for deposit growth appears to relate to consumer preference for guaranteed
     returns on certificate of deposit products versus stock market equities as
     well as less attention by customers to managing down their checking account
     balances due to the low interest rate environment.

o    Net charge-offs for the three months ended June 30, 2001 were $1.53
     million, up $300,000 or 23% over first quarter 2001. The primary component
     of this increase was $485,000 in charge-offs due to several installment
     loans discovered in the late spring to be fraudulent. For the first six
     months of the year, the net charge-offs/average loans ratio was .36%, 11
     basis points above the same 2000 period, but comparable to or more
     favorable than the averages for full-year 1999 and 1998 of .33% and .45%,
     respectively. Nonperforming assets at June 30, 2001 decreased 6.3% from the
     March 31 level and are $5.5 million or 72% higher than one year earlier.
     The primary reasons for the increase are the 90-day delinquency ($3.9
     million) of a significant commercial loan customer and $900,000 more in
     foreclosed property. The nonperforming loan ratio at quarter end was .71%
     versus .44% for the same period last year. Loan loss reserve coverage was
     1.87 times based on a 1.33% ratio to loans outstanding; this compares to
     306% coverage and a 1.33% reserve ratio at June 30, 2000.






                                       18



o    The Company's efficiency ratio, excluding intangible amortization, net
     securities losses, and one-time acquisition-related expenses, increased to
     56.1% for the second quarter of 2001 versus 54.9% for the same period last
     year. Besides what the Company believes to be a temporarily higher level of
     miscellaneous expenses not readily isolated as one-time acquisition costs,
     the increase in the efficiency ratio also reflects the Company's relatively
     modest operating income growth (up 4.8%) due to the slowing economy. In
     addition, costs associated with the Company's growing financial services
     businesses have a higher efficiency ratio by their nature.

o    Assets under management exceeded $1.36 billion as of quarter end, unchanged
     from the March 31, 2001 level, despite the volatility of the equity
     markets. Growth was strongest in retirement plan trusts generated by CBU's
     Benefit Plans Administrative Services subsidiary as well as assets
     originated through Community Investment Services. Revenue streams from
     these businesses along with the stability of the Company's personal trust
     products more than offset present softness in the growth-oriented
     investment management assets of the Elias Asset Management (EAM)
     subsidiary. Second quarter revenues from EAM were unchanged from the same
     period last year due to the favorable impact of new business on its fee
     structure. Compared to June 30, 2000, including an estimate for
     discretionary assets managed by the First Liberty trust department, assets
     under management are approximately 2% higher.


MISCELLANEOUS ITEMS

LIQUIDITY

Due to the potential for unexpected fluctuations in deposits and loans, active
management of the Company's liquidity is critical. In order to respond to these
circumstances, a variety of balance sheet funding sources is in place, largely
using collateralized borrowings through the Federal Home Loan Bank, the Federal
Reserve, and major brokerage firms.

The Company's primary approach to measuring liquidity is known as the Basic
Surplus/Deficit model. It is used to calculate liquidity over two time periods:
first, the relationship within 30 days between liquid assets and short-term
liabilities which are vulnerable to nonreplacement; and second, a projection of
subsequent cash availability over an additional 60 days. The minimum policy
level of liquidity under the Basic Surplus/Deficit approach is 7.5% of total
assets for both the 30 and 90-day time horizons. As of June 30, 2001, this ratio
was 14.6% and 14.3%, respectively, excluding the Company's capacity to borrow
additional funds from the Federal Home Loan Bank.

EFFECTS OF INFLATION

The financial statements and related data presented herein have been prepared in
accordance with generally accepted accounting principles in the United States,
which require the measurement of financial position and operating results in
terms of historical dollars without considering changes in the relative
purchasing power of money over time due to inflation.

Virtually all of the assets and liabilities of the Company are monetary in
nature. As a result, interest rate changes have a more significant impact on the
Company's performance than general levels of inflation.

SUPPLEMENTAL SCHEDULES

A)   The following table sets forth certain information concerning average
     interest-earning assets and interest-bearing liabilities and the yields and
     rates thereon. Interest income and resultant yield information in the
     tables are on a fully tax-equivalent basis using a marginal federal income
     tax rate of 35%. Averages are computed on daily average balances for each
     month in the period divided by the number of days in the period. Yields and
     amounts earned include loan fees. Nonaccrual loans have been included in
     interest earnings for purposes of these computations.

     average balances and rates of the totals; they are not a summation of the
     changes of the components.

The impact of interest not recognized on nonaccrual loans, and interest income
that would have been recorded if the restructured loans had been current in
accordance with their original terms, was immaterial. The Company's policy is to
place a loan on a nonaccrual status and recognize income on a cash basis when it
is more than ninety days past due, except when in the opinion of management it
is well secured and in the process of collection.

Item 3.  Quantitative and Qualitative Disclosure about Market Risk

INTEREST RATE RISK

Market risk is the risk of loss in a financial instrument arising from adverse
changes in market rates/prices such as interest rates, foreign currency exchange
rates, commodity prices, and equity prices. The Company's primary market risk
exposure is interest rate risk. The ongoing monitoring and management of this
risk, over both a short-term tactical and longer-term strategic time horizon, is
an important component of the Company's asset/liability management process,
which is governed by policies established by its Board of Directors and reviewed
and approved annually. The Board of Directors delegates responsibility for
carrying out the asset/liability management policies to the Asset/Liability
Management Committee (ALCO). In this capacity, ALCO develops guidelines and
strategies impacting the Company's asset/liability management activities based
upon estimated market risk sensitivity, policy limits, and overall market
interest rate-related level and trends.

As the Company does not believe it is possible to reliably predict future
interest rate movements, it has maintained an appropriate process and set of
measurement tools which enable it to identify and quantify sources of interest
rate risk. The primary tool used by the Company in managing interest rate risk
is income simulation. The analysis begins by measuring the impact of differences
in maturity and repricing of each balance sheet position. Such work is further
augmented by adjusting for prepayment and embedded option risk found naturally
in certain asset and liability classes. Finally, balance sheet growth and
funding expectations are added to the analysis in order to reflect the strategic
initiatives set forth by the Company.





                                       28



Changes in net interest income are reviewed after subjecting the balance sheet
to an array of Treasury yield curve possibilities, including an up or down 200
basis point (BP) movement in rates from current levels. While such an aggressive
movement in rates provides management with good insight as to how the Company's
net interest income may perform under extreme market conditions, results from a
more modest shift in interest rates are used as a basis to conduct day-to-day
business decisions.

The following reflects the Company's one-year net interest income sensitivity
based on asset and liability levels on June 30, 2001, assuming no growth in the
balance sheet, and assuming a 200 basis point instantaneous rate change in the
prime rate, federal funds rate and the entire Treasury yield curve.

                                REGULATORY MODEL

                            Net Interest Income
      Rate Change              Dollar Change            Percent of Flat Rate
    In Basis Points              (in 000's)              Net Interest Income
    ---------------         -------------------         --------------------
        +200 bp                  $(3,953)                       -3.8%
        -200 bp                  $(4,972)                       -4.8%

A second simulation was performed based on what the Company believes to be
conservative levels of balance sheet growth--approximately 6% growth in loans,
4% growth in investments, 3% growth in deposits, necessary increases in
borrowings to support earning asset grown, with no growth in any other major
portions of the balance sheet--along with 200 BP movements over a twelve month
period in the prime rate, federal funds rate, and a Treasury yield curve moving
closer to historical spreads to fed funds.

                                MANAGEMENT MODEL

                            Net Interest Income
      Rate Change              Dollar Change            Percent of Flat Rate
    In Basis Points              (in 000's)              Net Interest Income
    ---------------         -------------------         --------------------
        +200 bp                   $(1,440)                      -1.4%
        -200 bp                     $(957)                       -.9%

The preceding interest rate risk analysis does not represent a Company forecast
and should not be relied upon as being indicative of expected operating results.
These hypothetical estimates are based upon numerous assumptions including: the
nature and timing of interest rate levels including yield curve shape,
prepayments on loans and securities, deposit decay rates, pricing decisions on
loans and deposits, reinvestment/replacement of asset and liability cash flows,
and others. While the assumptions are developed based upon current economic and
local market conditions, the Company cannot make any assurances as to the
predictive nature of these assumptions, including how customer preferences or
competitor influences might change. Furthermore, the sensitivity analysis does
not reflect actions that ALCO might take in responding to or anticipating
changes in interest rates.
