                         Report of Independent Auditors

Compensation Committee and Participants of
Community Bank System, Inc.
   Employee Savings and Retirement Plan

In our opinion, the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of Community Bank System, Inc. Employee Savings and Retirement Plan (the "Plan")
at December 31, 2002 and 2001, and the changes in net assets available for
benefits for the years then ended in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan'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 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 provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes is presented for the purpose of additional analysis and
is not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

--------------------------------------------------------------------------------

A.    Description of the Plan

      The following description of the Community Bank System, Inc. Employee
      Savings and Retirement Plan ("the Plan") provides only general
      information. Participants should refer to the Plan agreement for a more
      complete description of the Plan's provisions.

      General

      The Plan is a defined contribution plan which covers substantially all
      Community Bank System, Inc. (the "Company") employees who are age eighteen
      or older. Employees must have 1 year of service to be eligible for the
      Company's contribution. The Plan is subject to the provisions of the
      Employment Retirement Income Security Act of 1974 (ERISA).

      Contributions

      Participants may make voluntary contributions of up to 90% of their total
      compensation on a pre-tax or after-tax basis up to a maximum contribution
      of $11,000. Voluntary cash contributions of up to 6% of total eligible
      compensation are matched 50% by the Company and amounted to $723,732 and
      $534,988 in 2002 and 2001, respectively. In addition, the Company may make
      discretionary profit sharing contributions to the Plan which are allocated
      to individual participant accounts. Such voluntary contributions amounted
      to $388,135 and $303,525 in 2002 and 2001, respectively. Within certain
      maximum limitations, the amount of the Bank's annual discretionary
      contributions are determined by the Board of Directors.

      Participant Accounts

      Each participant's account is credited with the participant's contribution
      and allocations of (a) the Company's contribution and (b) Plan earnings,
      and charged with an allocation of administrative expenses. Allocation of
      Plan earnings and administrative expenses are based on participant
      earnings or account balances, as defined. The benefit to which a
      participant is entitled is the benefit that can be provided from the
      participant's vested account. Forfeited accounts are allocated annually to
      eligible participant accounts based on the ratio of each eligible
      participant's compensation to total eligible participant compensation.
      Forfeited accounts allocated to eligible participants amounted to $9,087
      and $16,628 for 2002 and 2001, respectively.

      Vesting

      Participants are immediately vested in their contributions and the
      Company's discretionary profit sharing contributions. Vesting in the
      Company's matching contribution portion plus actual earnings thereon is
      based on years of continuous service. A participant is 100 percent vested
      after three years of service.

      Participant Loans

      Participants may borrow from the Plan a minimum of $1,000 up to a maximum
      equal to the lesser of $50,000 or 50 percent of their vested account
      balance. Loans are secured by the balance in the participant's account and
      bear interest at a rate of prime plus two percent.

      Payment of Benefits

      Normal retirement date for participants under the Plan is the later of age
      65 or the completion of 5 years of service. Upon termination of service
      due to death, disability or retirement, the participant will receive
      either a lump sum amount or installment payments equal to the value of the
      participant's vested interest in his or her account.

      Plan Termination

      Although it has not expressed any intent to do so, the Bank has the right
      under the Plan to discontinue contributions at any time and terminate the
      Plan subject to the terms of ERISA. In the event of a termination of the
      Plan, the net assets of the Plan are to be set aside for participating
      employees based upon balances then credited to individual accounts.
      Participants shall be vested 100% in the assets so allocated to their
      accounts.

B.    Significant Accounting Policies

      Basis of Accounting

      The financial statements included herein have been prepared on an accrual
      basis of accounting in accordance with accounting principles generally
      accepted in the United States of America.

      Investments

      Investments are stated at aggregate fair value, except for the SEI Stable
      Asset GIC Fund which is stated at cost. Securities which are traded on a
      national securities exchange are valued at the last reported sales price
      on the last business day of the Plan year. Participant loan receivable
      balances are reported at cost.

      The Plan presents in the statement of changes in net assets, the net
      appreciation (depreciation) in the fair value of its investments which
      consists of realized gains or losses and unrealized appreciation
      (depreciation) on those investments.

      Purchases and sales of securities are recorded on the settlement date.
      Gains or losses on sales of securities are based on average cost. Interest
      income is recorded on the accrual basis. Dividends are recorded on the
      ex-dividend date.

      Payment of Benefits

      Benefits are recorded when paid.

      Inactive Accounts

      Account balances of individuals who have withdrawn from participation in
      the Plan were approximately $5,540,627 and $4,731,372 at December 31, 2002
      and 2001, respectively.

      Transfers in From Merged Plans

      During 2001, the Company acquired First Liberty Bank Corp. and Citizens
      National Bank of Malone. Subsequent to acquisition the defined
      contribution plans were terminated and merged into the Company plan.

      Use of Estimates

      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 disclosures 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.

      Risks and Uncertainties

      The plan provides for various investment options in combination of mutual
      funds and Company stock. Investment securities are exposed to various
      risks, such as interest rate, market and credit. Due to the level of risk
      associated with certain investment securities and the level of uncertainty
      related to changes in the value of investment securities, it is at least
      reasonably possible that changes in risk in the near term would materially
      affect participants' account balances and the amounts reported in the
      statement of net assets available for plan benefits and the statement of
      changes in net assets available for plan benefits.

C.    Investments

      Investments are held within various common funds maintained by the
      Community Bank, N.A. Trust Department. Participants, at their discretion,
      may allocate contributions and account balances between various investment
      options offered by the Plan. The Plan administrator's description of these
      options is as follows:

      Community Bank System, Inc. Stock Fund and Payroll Stock Ownership Fund -
      these Funds invest in the common stock of the Plan sponsor, which is
      traded on the New York Stock Exchange under the symbol "CBU".

      Guaranteed Investment Contract Fund - invests in the SEI Stable Asset GIC
      Fund, a mutual fund that holds primarily a diversified portfolio of stable
      value contracts issued by insurance companies and banks. Investments in
      the SEI Stable Asset GIC Fund are not marketable securities and are
      reported at cost.

      Washington Mutual Investors Fund - a mutual fund that invests in common
      stocks and securities convertible into such common stocks.

      Federated Total Return Bond Fund - a mutual fund seeking to provide total
      return by investing primarily in a diversified portfolio of investment
      grade fixed income securities.

      Manager Special Equity Fund - a mutual fund that invests in equity
      securities of small- and medium-sized U.S. companies.

      Massachusetts Investors Growth Fund - a mutual fund that invests in common
      stocks and securities convertible into common stocks that offer long-term
      growth.

      EuroPacific Growth Fund - a mutual fund that invests in stocks of issuers
      located in Europe or the Pacific Basin.

      Dreyfus S&P 500 Index Fund - a mutual fund that invests in equities and
      seeks to match the performance of the S&P 500 Composite Stock Price Index.

      Federated Mid-Cap Index Fund - a mutual fund primarily that invests in
      stocks of U.S. companies.

      TD Waterhouse IDA Account - participants select the investment securities
      including equity securities, stocks and bonds.

D.    Transactions with Parties-in-Interest

      purchased 52,935 and 83,301 shares of Community Bank System, Inc. common

E.    Income Tax Status

      The Plan obtained its most recent determination letter on December 27,
      1995, in which the Internal Revenue Service stated that the plan, as then
      designed, was in compliance with Section 401(a) of the Internal Revenue
      Code. The Plan has been amended since receiving the determination letter,
      however, the Plan administrator and the Plan's tax counsel believe that
      the Plan is currently designed and being operated in compliance with the
      applicable requirements of the Internal Revenue Code.
