The remainder of the Original Form 10-K is unchanged and is not reproduced in
this Amendment No. 1. This Amendment No. 1 speaks as of the filing date of the

COMMUNITY BANK SYSTEM, INC.

NOTE A: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Community Bank System, Inc. is a single bank holding company which wholly-owns
four consolidated subsidiaries: Community Bank, N.A. (the Bank), Benefit Plans
Administrative Services, Inc. (BPAS), CFSI Closeout Corp. (CFSICC), and First of
Jermyn Realty Co. (FJRC). BPAS owns two subsidiaries, Benefit Plans
Administrative Services LLC and Harbridge Consulting Group LLC. BPAS provides
administration, consulting and actuarial services to sponsors of employee
benefit plans. CFSICC and FJRC are inactive companies.

The Bank operates 125 customer facilities throughout 22 counties of Upstate New
York and five counties of Northeastern Pennsylvania. The Bank owns the following
subsidiaries: Community Investment Services, Inc. (CISI), CBNA Treasury
Management Corporation (TMC), CBNA Preferred Funding Corporation (PFC), Elias
Asset Management, Inc. (EAM) and First Liberty Service Corp. (FLSC). CISI
provides broker-dealer and investment advisory services. TMC operates the cash
management, investment, and treasury functions of the Bank. PFC primarily is an
investor in residential real estate loans. EAM provides asset management
services to individuals, corporate pension and profit sharing plans, and
foundations. FLSC provides banking-related services to the Pennsylvania branches
of the Bank.

The Company wholly-owns three unconsolidated subsidiary business trusts formed
for the purpose of issuing mandatorily redeemable preferred securities which are
considered Tier I capital under regulatory capital adequacy guidelines (see Note
H).

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All inter-company accounts and transactions have
been eliminated in consolidation. Certain prior period amounts have been
reclassified to conform with the current period presentation.

Critical Accounting 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.
Critical accounting estimates include the allowance for loan losses, actuarial
assumptions associated with the pension, post-retirement and other employee
benefit plans, the provision for income taxes, and the carrying value of
goodwill and other intangible assets.

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 basis, 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 regulations of various governmental 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 loan loss allowances, and operating restrictions resulting from the
regulators' judgements based on information available to them at the time of
their examinations.

Revenue Recognition

The Company recognizes income on an accrual basis. CISI recognizes fee income
when investment and insurance products are sold to customers. EAM provides asset
management services to brokerage firms and clients and recognizes income ratably
over the contract period during which service is performed. Revenue from BPA's
administration and recordkeeping services is recognized ratably over the service
contract period. Revenue from consulting and actuarial services is recognized
when services are rendered. All inter-company revenue and expense among related
entities are eliminated in consolidation.


                                       9


Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash on
hand, amounts due from banks and highly liquid investments with original
maturities of less than ninety days. 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. 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 has been classified as trading securities. Equity securities are
stated at cost and include restricted stock of the Federal Reserve Bank of New
York and Federal Home Loan Bank of New York. Investment securities are reviewed
regularly for other than temporary impairment. Where there is other than
temporary impairment, the carrying value of the investment security is reduced
to the estimated fair value, with the impairment loss recognized in the
consolidated statements of income as other expense.

The average cost method is used in determining the realized gains and losses on
sales of investment securities. 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.

Loans

Loans are stated at unpaid principal balances, net of unearned income. Mortgage
loans held for sale are carried at the lower of cost or fair value and are
included in loans as the balance of such loans was not significant. Fair values
for variable rate loans that reprice frequently 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. The carrying amount of accrued interest approximates
its fair value.

Interest on loans 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 interest method.
Non-refundable loan fees and related direct costs are included in the loan
balances and are deferred and amortized over the life of the loan as an
adjustment to loan yield using the effective interest method. Premiums and
discounts on purchased loans are amortized on an accelerated method over the
life of the loans.

Impaired and Other Nonaccrual Loans

The Company places a loan on nonaccrual status when the loan becomes ninety days
past due (or sooner, if management concludes collection is doubtful), except
when, in the opinion of management, it is well-collateralized and in the process
of collection. A loan may be placed on nonaccrual status earlier than ninety
days past due if there is deterioration in the financial position of the
borrower or if other conditions of the loan so warrant. When a loan is placed on
nonaccrual status, uncollected accrued interest is reversed against interest
income and the deferral and amortization of non-refundable loan fees and related
direct costs is discontinued. Interest income during the period the loan is on
nonaccrual status is recorded on a cash basis after recovery of principal is
reasonably assured. Nonaccrual loans are returned to accrual status when
management determines that the borrower's performance has improved and that both
principal and interest are collectible. This generally requires a sustained
period of timely principal and interest payments.

Commercial loans greater than $500,000 are evaluated individually for impairment
in accordance with FASB No. 114, "Accounting by Creditors for Impairment of a
Loan." A loan is considered impaired, based on current information and events,
if it is probable that the Company will be unable 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 upon
the present value of expected future cash flows or the fair value of the
collateral, if the loan is collateral-dependent.

The Company's charge-off policy by loan type is as follows:

o     Commercial loans are generally charged-off to the extent outstanding
      principal exceeds the fair value of estimated proceeds from collection
      efforts, including liquidation of collateral. The charge-off is recognized
      when the loss becomes reasonably quantifiable.


                                       10


o     Consumer installment loans are generally charged-off to the extent
      outstanding principal balance exceeds the fair value of collateral, and
      are recognized by the end of the month in which the loan becomes 120 days
      past due.

o     Loans secured by 1-4 family residential real estate are generally
      charged-off to the extent outstanding principal exceeds the fair value of
      the property, and are recognized when the loan becomes 180 days past due.

Allowance for Loan Losses

Management continually evaluates the credit quality of the Company's loan
portfolio, and performs a formal review of the adequacy of the allowance for
loan losses on a quarterly basis. The allowance reflects management's best
estimate of probable losses inherent in the loan portfolio. Determination of the
allowance is subjective in nature and requires significant estimates. The
Company's allowance methodology consists of two broad components, general and
specific loan loss allocations.

The general loan loss allocation is composed of two calculations that are
computed on four main loan segments: commercial, consumer direct, consumer
indirect and residential real estate. The first calculation determines an
allowance level based on the latest three years of historical net charge-off
data for each loan category (commercial loans exclude balances with specific
loan loss allocations). The second calculation is qualitative and takes into
consideration five major factors affecting the level of loan loss risk:
portfolio risk migration patterns (internal credit quality trends); the growth
of the segments of the loan portfolio; economic and business environment trends
in the Company's markets (includes review of bankruptcy, unemployment,
population, consumer spending and regulatory trends); industry, geographical and
product concentrations in the portfolio; and the perceived effectiveness of
managerial resources and lending practices and policies. These two calculations
are added together to determine the general loan loss allocation. The specific
loan loss allocation relates to individual commercial loans that are both
greater than $0.5 million and in a non-accruing status with respect to interest.
Specific losses are based on discounted estimated cash flows, including any cash
flows resulting from the conversion of collateral.

Loan losses are charged off against the allowance, while recoveries of amounts
previously charged off are credited to the allowance. A provision for loan loss
is charged to operations based on management's periodic evaluation of factors
previously mentioned.

Intangible Assets

Intangible assets include core deposit intangibles, customer relationship
intangibles and goodwill arising from acquisitions. Core deposit intangibles and
customer relationship intangibles are amortized on either an accelerated or
straight-line basis over periods ranging from 7 to 20 years. Goodwill is
evaluated at least annually for impairment. The carrying value of goodwill and
other intangible assets is based upon discounted cash flow modeling techniques
that require management to make estimates regarding the amount and timing of
expected future cash flows. It also requires use of a discount rate that
reflects the current return requirements of the market in relation to present
risk-free interest rates, required equity market premiums, and company-specific
risk indicators.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation.
Computer software costs that are capitalized only include external direct costs
of obtaining and installing the software. The annual provision for depreciation
is computed using the straight-line method over the assets' estimated useful
lives. Maintenance and repairs are charged to expense as incurred.

Long-lived depreciable assets are evaluated periodically for impairment when
events or changes in circumstances indicate the carrying amount may not be
recoverable. Impairment exists when the expected undiscounted future cash flows
of a long-lived asset are less than its carrying value. In that event, the
Company recognizes a loss for the difference between the carrying amount and the
estimated fair value of the asset based on a quoted market price, if applicable,
or a discounted cash flow analysis. Impairment losses are recorded in other
expenses on the income statement.

Other Real Estate

Properties acquired through foreclosure, or by deed in lieu of foreclosure, are
carried at the lower of the unpaid loan balance or fair value less estimated
costs of disposal. Subsequent changes in value are reported as adjustments to
the carrying amount, not to exceed the initial carrying value of the asset at
the time of transfer. Changes in value subsequent to transfer are recorded in
operating expenses on the income statement. Gains or losses not previously
recognized resulting from the sale of other real estate are recognized as an
expense on the date of sale. At December 31, 2004 and 2003, other real estate,
included in other assets, amounted to $1,645,000 and $1,077,000, respectively.


                                       11


Mortgage Servicing Rights

Originated mortgage servicing rights are recorded at their allocated fair value
at the time of sale of the underlying loan, and are amortized in proportion to
and over the period of estimated net servicing income or loss. The Company 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 Company incorporates assumptions that market participants would use in
estimating future net servicing income, which includes estimates of the
servicing cost 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.

Deposits

The fair value of deposit obligations are based on current market rates for
alternative funding sources, principally the Federal Home Loan Bank of New York.
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 and interest rates currently being offered
on similar borrowings.

Since the Company considers debt extinguishments to be a component of its
interest rate risk management, any related gains or losses are not deemed
extraordinary and are presented in the non-interest income section of the
consolidated statements of income.

Treasury Stock

On June 9, 2003, the Company announced a twelve-month authorization to
repurchase up to 1,400,000 of its outstanding shares in open market or privately
negotiated transactions. As of December 31, 2004, the Company has repurchased
all of the shares at an aggregate cost of $30,199,000 or $21.57 per share. The
repurchases were for general corporate purposes, including those related to
acquisition and stock plan activities.

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.

Retirement Benefits

The Company provides defined benefit pension benefits and post-retirement health
and life insurance benefits to eligible employees. The Company also provides
deferred compensation and supplemental executive retirement plans for selected
current and former employees and officers. Expense under these plans is charged
to current operations and consists of several components of net periodic benefit
cost based on various actuarial assumptions regarding future experience under
the plans, including discount rate, rate of future compensation increases and
expected return on plan assets.

Assets Under Management or Administration

Assets held in fiduciary or agency capacities for customers are not included in
the accompanying consolidated statements of condition as they are not assets of
the Company. Substantially all fees associated with providing asset management
services are recorded on an accrual basis of accounting and are included in
non-interest income. Assets under management or administration at December 31,
2004 and 2003 were $2,102,000,000 and $1,807,000,000, respectively.

Earnings Per Share

Basic earnings per share are computed based on the weighted-average common
shares outstanding for the period. Diluted earnings per share are based on the
weighted-average shares outstanding adjusted for the dilutive effect of the
assumed exercise of stock options during the year. The dilutive effect of
options is calculated using the treasury stock method of accounting. The
treasury stock method determines the number of common shares that would be
outstanding if all the dilutive options (average market price is greater than
the exercise price) were exercised and the proceeds were used to repurchase
common shares in the open market at the average market price for the applicable
time period.


                                       12


At a special meeting of the shareholders held on March 26, 2004, the
shareholders approved an amendment to the certificate of incorporation of the
Company to increase the number of authorized shares of common stock to 50
million. This amendment was effected in connection with the previously announced
two-for-one stock split of the Company's common stock. The stock split was
effected in the form of a 100 percent stock dividend, and was paid on April 12,
2004 to shareholders of record on March 17, 2004. Accordingly, all share, option
and per-share amounts have been adjusted in the consolidated financial
statements to reflect the stock split.

Stock-Based Compensation

The Company accounts for stock-based awards issued to directors, officers and
key employees using the intrinsic value method. This method requires that
compensation expense be recognized to the extent that the fair value of the
underlying stock exceeds the exercise price of the stock award at the grant
date. The Company generally does not recognize compensation expense related to
stock awards because the stock awards generally have fixed terms and exercise
prices that are equal to or greater than the fair value of the Company's common
stock at the grant date.

SFAS 123, "Accounting for Stock-Based Compensation," requires companies that use
the "intrinsic value method" to account for stock compensation plans to provide
pro forma disclosures of the net income and earnings per share effect of stock
options using the "fair value method." Under this method, the fair value of the
option on the date of grant is recognized ratably as compensation expense over
the vesting period of the option.

Management estimated the fair value of options granted using the Black-Scholes
option-pricing model. This model was originally developed to estimate the fair
value of exchange-traded equity options, which (unlike employee stock options)
have no vesting period or transferability restrictions. As a result, the
Black-Scholes model is not necessarily a precise indicator of the value of an
option, but it is commonly used for this purpose. The Black-Scholes model
requires several assumptions, which management developed based on historical
trends and current market observations. These assumptions include:



                                                  2004            2003          2002
----------------------------------------------------------------------------------------
                                                                     
Weighted-average expected life (in years)       7.33-7.43       7.55-8.76           6.74
Future dividend yield                                3.00%           3.00%          3.00%
Share price volatility                       26.88%-27.02%   25.59%-27.58%         27.82%
Weighted average risk-free interest rate       4.02%-4.45%     3.82%-4.03%    3.81%-5.16%
========================================================================================


If these assumptions are not accurate, the estimated fair value used to derive
the information presented in the following table also will be inaccurate.
Moreover, the model assumes that the estimated fair value of an option is
amortized over the option's vesting period and would be included in salaries and
employee benefits on the income statement.

The pro forma impact of applying the fair value method of accounting for the
periods shown below may not be indicative of the pro forma impact in future
years.

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. SFAS 107, "Disclosures about Fair Value of Financial Instruments,"
excludes certain financial instruments and all non-financial 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.

New Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board revised SFAS No. 123,
"Accounting for Stock-Based Compensation." SFAS 123R establishes accounting
requirements for share-based compensation to employees and carries forward prior
guidance on accounting for awards to non-employees. The provisions of this
statement will become effective July 1, 2005 for all equity awards granted after
the effective date. SFAS 123R requires an entity to recognize compensation
expense based on an estimate of the number of awards expected to actually vest,
exclusive of awards expected to be forfeited. Management does not expect the
impact of the adoption of this pronouncement to be materially different from the
pro forma impacts disclosed under SFAS No. 123.

Management does not believe any individual unrealized loss as of December 31,
2004 represents an other than temporary impairment. The unrealized losses
reported for the agency and mortgage-backed securities relate primarily to
securities issued by FHLB, FNMA and FHLMC and are currently rated AAA by Moody's
Investor Services and Standards & Poor. The unrealized losses in the portfolios
are primarily attributable to changes in interest rates. The Company has both
the intent and ability to hold these securities for the time necessary to
recover the amortized cost. The unrealized losses of $3,095,000 as of December
31, 2003 were less than 12 months old.

The amortized cost and estimated fair value of debt securities at December 31,
2004, by contractual maturity, are shown below. Expected maturities will differ
from contractual maturities because borrowers may have the right to call or
prepay obligations with or without call or prepayment penalties.

The estimated fair value of long-term borrowings at December 31, 2004 and 2003
was approximately $319.0 million and $314.0 million, respectively.

In December 2003, the Company prepaid $25.0 million of Federal Home Loan Bank
("FHLB") advances with maturity dates ranging from January 30, 2008 to February
4, 2008 and a weighted-average rate of 5.31%. In December 2002, the Company
prepaid $11.0 million of FHLB advances with maturity dates ranging from December
15, 2003 to December 31, 2004 and a weighted-average rate of 6.17%. As a result
of these prepayments, the Company incurred penalties of $2.6 million in 2003 and
$925,000 in 2002. These penalties have been reflected in the consolidated
statements of income as gain (loss) on investment securities and debt
extinguishments.

The Company sponsors three business trusts, Community Capital Trust I, Community
Capital Trust II, and Community Statutory Trust III, of which 100% of the common
stock is owned by the Company. The trusts were formed for the purpose of issuing
company-obligated mandatorily redeemable preferred securities to third-party
investors and investing the proceeds from the sale of such preferred securities
solely in junior subordinated debt securities of the Company. The debentures
held by each trust are the sole assets of that trust. Distributions on the
preferred securities issued by each trust are payable semi-annually at a rate
per annum equal to the interest rate being earned by the trust on the debentures
held by that trust. The preferred securities are subject to mandatory
redemption, in whole or in part, upon repayment of the debentures. The Company
has entered into agreements which, taken collectively, fully and unconditionally
guarantee the preferred securities subject to the terms of each of the
guarantees. The terms of the preferred securities of each trust are as follows:



      Issuance                          Interest             Maturity            Call                        Call

====================================================================================================================================


In the fourth quarter 2003, as a result of applying the provisions of FIN 46,
the Company de-consolidated these subsidiary trusts from its financial
statements. The de-consolidation of the net assets and results of operations of
the trusts had an immaterial impact on the Company's financial statements. The
Company continues to be obligated to repay the debentures held by the trusts and
guarantees repayment of the preferred securities issued by the trusts. The
preferred securities held by the trusts qualify as Tier I capital for the
Company under Federal Reserve Board guidelines.

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.

A reconciliation of the differences between the federal statutory income tax
rate and the effective tax rate for the years ended December 31 is shown in the
following table:

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 addition 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, 2004, the Bank
had approximately $27,758,000 in undivided profits legally available for the
payments of dividends.


                                       21


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 is 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

Pension and post-retirement plans The Company provides defined benefit pension
and other post-retirement health and life insurance benefits to qualified
employees and retirees. Using a measurement date of December 31, the following
table shows the funded status of the Company's plans reconciled with amounts
reported in the Company's consolidated statements of condition:

In 2004, the Company amended its defined benefit pension plan to allow for a
cash balance option. Participants in the plan as of December 31, 2003 were given
an option to continue to have their benefits calculated under the traditional
plan formula or have their benefits determined as an account balance under a
cash balance formula. All new participants to the plan will automatically
participate in the cash balance option. In addition, the plan was amended to
provide for the payment of certain benefits formerly accrued and payable under
the Deferred Compensation Plan for Certain Executive Employees.

The Company has unfunded supplemental pension plans for certain key executives.
The projected benefit obligation and accrued benefit cost included in the
preceding table related to these plans was $3,128,000 and $2,798,000 for 2004
and $2,606,000 and $2,245,000 for 2003, respectively. The accumulated benefit
obligation for the defined benefit pension was $40,659,000 and $35,025,000 as of
December 31, 2004 and 2003, respectively.

Other expense represents a $1.2 million adjustment recorded in the fourth

December 31 are as follows:



                                        Pension Benefits          Post-retirement Benefits

The amount of benefit payments that are expected to be paid over the next ten
years are as follows:

                         Pension     Post-retirement
(000's omitted)          Benefits        Benefits

           2005           $2,866                $289
           2006            2,666                 308
           2007            3,278                 332
           2008            4,607                 350
           2009            3,302                 383
      2010-2014          $21,541              $2,577
====================================================

The payments reflect future service and are based on various assumptions
including retirement age and form of payment (lump-sum versus annuity). Actual
results may differ from these estimates.

The expected long-term rate of return was estimated by taking into consideration
asset allocation, reviewing historical returns on type of assets held and
current economic factors. The asset allocation for the defined benefit pension
plan as of December 31, by asset category, is as follows:

                           2004      2003
-----------------------------------------
  Equity securities         69%        70%
  Debt securities           19%        20%
  Cash                      12%        10%
-----------------------------------------
     Total                 100%       100%
=========================================


                                       23


Plan assets include $2,571,000 (6%) and $2,230,000 (6%) of Community Bank
System, Inc. stock at December 31, 2004 and 2003, respectively.

The investment objective for the defined benefit pension plan is to achieve an
average annual total return over a five-year period equal to the assumed rate of
return used in the actuarial calculations. At a minimum performance level, the
portfolio should earn the return obtainable on high quality intermediate-term
bonds. The Company's perspective regarding portfolio assets combines both
preservation of capital and moderate risk-taking. Asset allocation favors
equities, with a target allocation of approximately 75% equity securities, 20%
fixed income securities and 5% cash. No more than 10% of the portfolio can be in
stock of the Company. Due to the volatility in the market, the target allocation
is not always desirable and asset allocations will fluctuate between acceptable
ranges. Prohibited transactions include purchase of securities on margin,
uncovered call options, short sale transactions, and use of real estate,
unlisted limited partnerships, derivative products or venture capital loans as
fixed income investment vehicles.

The Company makes contributions to its funded qualified pension plan as required
by government regulation or as deemed appropriate by management after
considering the fair value of plan assets, expected return on such assets, and
the value of the accumulated benefit obligation. Based upon current information,
the Company does not expect to make contributions to the funded qualified
pension plan in 2005. The Company funds the payment of benefit obligations for
the supplemental pension and post-retirement plans because such plans do not
hold assets for investment.

The assumed health care cost trend rate used in the post-retirement health plan
at December 31,2004 was 9.0% for medical costs and 13.0% for prescription drugs.
The rate to which the cost trend rate is assumed to decline (the ultimate trend
rate) and the year that the rate reaches the ultimate trend rate is 5.0% and
2013, respectively.

Assumed health care cost trend rates have a significant effect on the amounts
reported for the health care plan. A one-percentage-point increase in the trend
rate would increase the service and interest cost components by $35,000 and
increase the benefit obligation by $264,000. A one-percentage-point decrease in
the trend rate would decrease the service and interest cost components by $8,000
and decrease the benefit obligation by $141,000.

401(k) Employee Stock Ownership Plan

The Company has a 401(k) Employee Stock Ownership Plan in which employees can
contribute from 1% to 90% of eligible compensation, with up to 6% being eligible
for matching contributions in the form of Company common stock. The Plan also
permits the Company to distribute a discretionary profit-sharing component in
the form of Company common stock to all participants except certain executive
employees. The expense recognized under this plan for the years ended December
31, 2004, 2003 and 2002 was $1,583,000, $1,309,000 and $1,026,000, respectively.

Deferred Compensation Plan for Certain Executive Employees

The Company has a Deferred Compensation Plan for Certain Executive Employees in
which participants may contribute up to 15% of their eligible compensation less
any amounts contributed to the 401(k) Employee Stock Ownership Plan. Any
discretionary profit-sharing amounts that the executive receives from the
Company must be contributed to the Deferred Compensation Plan in the form of
Company common stock. The expense recognized under this plan for the years ended
December 31, 2004, 2003 and 2002 was $159,000, $119,000 and $68,000,
respectively.

Other Deferred Compensation Arrangements

In addition to the supplemental pension plans for certain executives, the
Company has nonqualified deferred compensation for several former directors,
officers, and key employees. All benefits provided under these plans are
unfunded and payments to plan participants are made by the Company. At December
31, 2004 and 2003, the Company has recorded a liability of $5,373,000 and
$3,775,000, respectively. The expense recognized under these plans for the years
ended December 31, 2004, 2003, and 2002 was $1,727,000, $947,000 and $398,000,
respectively.

Deferred Compensation Plan for Directors

Directors may defer all or a portion of their director fees under the Deferred
Compensation Plan for Directors. Under this plan, there is a separate account
for each participating director which is credited with the amount of shares
which could have been purchased with the director's fees as well as any
dividends on such shares. On the distribution date, the director will receive
common stock equal to the accumulated share balance in his account. As of
December 31, 2004 and 2003, there were 65,090 and 56,901 shares credited to the
participants' accounts, for which a liability of $1,097,000 and $894,000 was
accrued, respectively. The expense recognized under the plan for the years ended
December 31, 2004, 2003 and 2002, was $206,000, $113,000, and $106,000,
respectively.

Director Stock Balance Plan

The Company has a Stock Balance Plan for non-employee directors who have
completed six months of service. The Plan is a nonqualified, noncontributory
defined benefit plan. The Plan provides benefits for service prior to January 1,
1996 based on a predetermined formula and benefits for service after January 1,
1996 based on the performance of the Company's common stock. Participants become
fully vested after six years of service. The directors can elect to receive
offset stock options that


                                       24


may reduce the Company's liability under the Plan. These options vest
immediately and expire one year after the date the director retires or two years
in the event of death. Benefits are payable in the form of cash and/or Company
stock (as elected by the director) on January 1st of the year after the director
retires from the Board. As of December 31, 2004 and 2003, the accrued pension
liability was $287,000 and $251,000, respectively. The expense recognized under
this plan for the years ended December 31, 2004, 2003 and 2002, was $36,000,
$38,000 and $69,000, respectively. The expense and related liability were
calculated using a dividend rate of 3.00%, stock price appreciation of 6.00%,
and a discount rate of 5.6% for 2004, 5.9% for 2003, and 6.10% for 2002.

NOTE L: STOCK-BASED COMPENSATION PLANS

The Company has a long-term incentive program for directors, officers, and key
employees. Under this program the Company authorized 4,024,000 shares of Company
common stock for the grant of incentive stock options, restricted stock awards,
nonqualified stock options, retroactive stock appreciation rights, and offset
options to its Stock Balance Plan (see Note K). The offset options vest and
become exercisable immediately and expire one year after the date the director
retires or two years in the event of death. The remaining options have a
ten-year term. They vest and become exercisable on a grant-by-grant basis,
ranging from immediate vesting to ratably over a five-year period. Option
activity in this plan is as follows:

The Company used the Black-Scholes option-pricing model to estimate the weighted
average grant date fair value. The assumptions used in the model are disclosed
in Note A - Stock Based Compensation. Compensation expense related to restricted
stock recognized in the income statement for the years ended December 31, 2004,
2003, and 2002 was $372,000, $105,000 and $353,000, respectively.

On February 21, 1995, the Company adopted a Stockholder Protection Rights
Agreement. Under the Plan, each stockholder received one right, representing the
right to purchase one share of common stock for $42.50 for each share of stock
owned. All of the rights expire on February 21, 2005, but the Company may redeem
the rights earlier for $.005 per right, subject to certain limitations. Rights
will become exercisable if a person or group acquires 15% or more of the
Company's outstanding shares. Until that time, the rights will trade with the
common stock; any transfer of common stock will also constitute a transfer of
the associated right. If the rights become exercisable, they will begin to trade
apart from the common stock. If one of a number of "flip-in events" occurs, each
right will entitle the holder to purchase common stock having a market value
equivalent of two times the exercise price. In January 2005, the Board of
Directors voted to permit the agreement to expire in February 2005.

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
and standby letters of credit. Commitments to extend credit are agreements to
lend to customers, generally having fixed expiration dates or other termination
clauses that may require payment of a fee. These commitments consist principally
of unused commercial and consumer credit lines. Standby letters of credit
generally are contingent upon the failure of the customer to perform according
to the terms of an underlying contract with a third party. The credit risks
associated with commitments to extend credit and standby letters of credit are
essentially the same as that involved with extending loans to customers and are
subject to normal credit policies. Collateral may be obtained based on
management's assessment of the customer's creditworthiness. The fair value of
these commitments is immaterial for disclosure in accordance with FASB
Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for
Guarantees, Including Indirect Guarantees of Indebtedness of Others". The
contract amount of commitment and contingencies is as follows:

(000's omitted)                         2004          2003
------------------------------------------------------------
Commitments to extend credit          $429,751      $315,898
Standby letters of credit               22,948        19,163
------------------------------------------------------------
     Total                            $452,699      $335,061
============================================================

The fair value of these financial instruments approximates carrying value.

The Company has unused lines of credit of $47,000,000 at December 31, 2004. The
Company has unused borrowing capacity of approximately $134,492,000 through
collateralized transactions with the Federal Home Loan Bank and $11,325,000
through collateralized transactions with the Federal Reserve 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 of December 23, 2004 through January 5, 2005 was
$58,779,000 of which $2,000,000 was required to be on deposit with the Federal
Reserve Bank of New York. The remaining $56,779,000 was represented by cash on
hand.

============================

NOTE P: REGULATORY MATTERS

The Company and the Bank are 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 Company's financial statements. Under capital adequacy
guidelines and the regulatory framework for prompt corrective action, the
Company and the Bank must meet specific capital guidelines that involve
quantitative measures of the Company's and the Bank's assets, liabilities, and
certain off-balance sheet items as calculated under regulatory accounting
practices. The Company's and 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 Company and Bank to maintain minimum total core capital to risk
weighted assets of 8%, and tier I capital to risk weighted assets and tier I
capital to average assets of 4%. Management believes, as of December 31, 2004,
that the Company and Bank meet all capital adequacy requirements to which they
are subject.

As of December 31, 2004 and 2003, the most recent notification from the Office
of the Comptroller of the Currency categorized the Company and Bank as "well
capitalized" under the regulatory framework for prompt corrective action. To be
categorized as "well capitalized," the Company and Bank must maintain minimum
total core capital to risk weighted assets of 10%, tier I capital to risk
weighted assets of 6% and tier I capital to average assets of 5%. There are no
conditions or events since that notification that management believes have
changed the institution's category. In addition, there were no significant
capital requirements imposed or agreed to during the regulatory approval process
of any of our acquisitions.

The capital ratios and amounts of the Company and the Bank as of December 31 are
presented below:

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal
control over financial reporting, as such term is defined in Exchange Act Rule
13a - 15(f). Under the supervision and with the participation of our management,
including our principal executive officer and principal financial officer, we
conducted an evaluation of the effectiveness of our internal control over
financial reporting based on the framework in Internal Control - Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission. Based on our evaluation under the framework in Internal Control -
Integrated Framework, our management concluded that our internal control over
financial reporting was effective as of December 31, 2004.

Our management's assessment of the effectiveness of our internal control over
financial reporting as of December 31, 2004 has been audited by
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as
stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

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

We have completed an integrated audit of Community Bank System, Inc.'s 2004
consolidated financial statements and of its internal control over financial
reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated
financial statements in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Our opinions, based on our audits,
are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the accompanying
index present fairly, in all material respects, the financial position of
Community Bank System, Inc. and its subsidiaries at December 31, 2004 and 2003,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 2004 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 conducted our audits of these statements in accordance with the
standards of the Public Company Accounting Oversight Board (United States).
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 of financial statements 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 provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management's assessment, included in Management's Report
on Internal Control Over Financial Reporting appearing under Item 8, that the
Company maintained effective internal control over financial reporting as of
December 31, 2004 based on criteria established in Internal Control - Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO), is fairly stated, in all material respects, based on those
criteria. Furthermore, in our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31,
2004, based on criteria established in Internal Control - Integrated Framework
issued by the COSO. The Company's management is responsible for maintaining
effective internal control over financial reporting and for its assessment of
the effectiveness of internal control over financial reporting. Our
responsibility is to express opinions on management's assessment and on the
effectiveness of the Company's internal control over financial reporting based
on our audit. We conducted our audit of internal control over financial
reporting in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material
respects. An audit of internal control over financial reporting includes
obtaining an understanding of internal control over financial reporting,
evaluating management's assessment, testing and evaluating the design and
operating effectiveness of internal control, and performing such other
procedures as we consider necessary in the circumstances. We believe that our
audit provides a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (i) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (ii)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (iii) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use, or disposition of the
company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting
may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.
