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 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 financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 2002 and 2001 and the changes in net assets available for plan benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held at end of year and reportable transactions are presented for the purpose of additional analysis and are not a required part of the basic financial statements, but are 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. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Participants should refer to the Plan agreement or summary plan document for more complete information. (a) GENERAL The Plan is a defined contribution plan as defined under Section 401 of the Internal Revenue Code (IRC), sponsored by NBT Bancorp Inc. (the Sponsor). The Sponsor is responsible for administration of the Plan. NBT Bank, N.A. - Trust Division (the Trustee), a wholly owned subsidiary of NBT Bancorp Inc., is the trustee of the Plan. The assets of the Plan are held, administered, and managed in accordance with the terms and conditions of the Trust Agreement, which is considered to be an integral part of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). (b) MERGERS On June 1, 2001, the Sponsor completed the acquisition of First National Bancorp, Inc. (FNB). Effective January 1, 2002, FNB's two defined contribution plans, First National Bank of Northern New York Employee Profit Sharing Plan and First National Bank of Northern New York ESOP (collectively referred to herein as the "FNB Plans"), were merged with and into the Plan. All participants in the FNB Plans that became employees of the Sponsor became participants in the Plan. The net assets of FNB Plans, consisting primarily of cash and NBT Bancorp Inc. common stock, were transferred to the Plan's trust on January 2, 2002 and January 3, 2002. Net assets merged into the Plan from the FNB Plans totaled $1,752,242. On November 8, 2001, the Sponsor merged with CNB Financial Corp. Effective December 31, 2001, CNB Financial Corp.'s defined contribution plan, the Central National Bank 401(k) Plan (the CNB Plan), was merged with and into the Plan. All participants in the CNB Plan that became employees of the Sponsor became participants in the Plan. The net assets of the CNB Plan, consisting primarily of loans, amounts due from broker, and NBT Bancorp Inc. common stock, were transferred to the Plan's trust on January 2, 2002 and January 3, 2002. Net assets merged into the Plan from the CNB Plan totaled $5,954,554 on December 31, 2001. While the transfers occurred on January 2, 2002 and January 3, 2002, the Plan recorded this transfer as of December 31, 2001, the effective date of the CNB Plan merger into the Plan. 5 NBT BANCORP INC. 401(K) AND EMPLOYEE STOCK OWNERSHIP PLAN Notes to Financial Statements December 31, 2002 and 2001 On February 17, 2000, May 5, 2000 and July 1, 2000 the Sponsor merged with Lake Ariel Bancorp, Inc., M. Griffith, Inc. and Pioneer American Holding Company Corp., respectively. All of the acquired companies had separate defined contribution plans. On January 1, 2001, the Pioneer American Bank, N.A. Savings and Investment Plan (Pioneer Plan), the LA Bank, N.A. Profit Sharing/401(k) Plan (LA Plan), the M. Griffith, Inc. 401(k) Plan (M. Griffith Plan) and the Pioneer American Bank, N.A. Employee Stock Ownership Plan (Pioneer ESOP), collectively referred to as the "Merged Plans," were merged into the Plan. All participants in the Merged Plans that became employees of the Sponsor became participants in the Plan. The assets held in the Merged Plans' various trusts that related to participants who became employees of the Sponsor were transferred to the Plan's trust at various dates during the year ended December 31, 2001. Changes in these net assets are included in the Plan's statement of changes in net assets available for plan benefits beginning on the date they were transferred into the Plan. These net assets consisted primarily of loans, cash, and NBT Bancorp Inc. common stock. The following represents the net assets transferred to the plan from the Merged Plans during the year ended December 31, 2001: DATE OF FINAL TRANSFER OF NET ASSETS MERGED PLAN NET ASSETS TO THE PLAN TRANSFERRED ---------------- ------------------------- ------------ Pioneer Plan February 1, 2001 $ 3,416,744 LA Plan June 11, 2001 3,417,711 M. Griffith Plan March 1, 2001 3,013,864 Pioneer ESOP May 3, 2001 3,884,603 ------------ $ 13,732,922 ============ (c) ELIGIBILITY All employees over age 21 with at least one year of service and who worked at least 1,000 hours in the Plan year are eligible to participate in the Plan. (d) CONTRIBUTIONS Participants make pre-tax contributions in whole percentages up to IRS limitations for any Plan year. The Sponsor provides a matching contribution of 100% of each participant's contribution up to 3% of their compensation. In addition, a discretionary amount, determined by the Sponsor's board of directors, may be contributed to the Plan each year. Participants must be actively employed on the last day of the year to share in this contribution, which is allocated to participants based on compensation. During 2002, a discretionary contribution of $545,213 was approved by the Sponsor's board of directors. This amount was paid during 2003. No discretionary contribution was approved by the Sponsor's board of directors during 2001. 6 NBT BANCORP INC. 401(K) AND EMPLOYEE STOCK OWNERSHIP PLAN Notes to Financial Statements December 31, 2002 and 2001 (e) PARTICIPANTS' ACCOUNTS Participants may elect to have their contributions invested among the various funds available to the Plan. All Sponsor contributions to the Plan are invested in the NBT Bancorp Inc. common stock. Each participant's account is credited with the Sponsor's and participant's contributions, plan earnings, and income, expenses, gains, and losses attributable thereto. (f) VESTING Participants' contributions and any investment income thereon are always 100% vested. Participants vest in the employer contributions on a straight line basis of 20% for each full year of service up to 100% vesting. Participants are considered 100% vested upon termination due to death, retirement, or permanent disability. (g) PARTICIPANT'S CLAIMS UPON PLAN TERMINATION Although it has not expressed any intention to do so, the Sponsor has the right to discontinue contributions or terminate the Plan at any time subject to Plan provisions. In the event of termination of the Plan, each participant's account would become fully vested. (h) FORFEITURES Forfeitures are applied to reduce the amount of subsequent employer contributions otherwise required to be paid. In 2002 and 2001, employer contributions were reduced by $45,431 and $109,138, respectively, from forfeited nonvested accounts. Forfeiture account balances totaled $32,576 at December 31, 2002. (i) PAYMENT OF BENEFITS Upon normal or early retirement, disability, death, or termination of employment, the value of a participant's account is paid in a single lump sum, as specified by the Plan. Early retirement is allowed upon reaching age 55 and completing 5 years of service. (j) PARTICIPANT LOANS Participants may borrow from their account in amounts ranging from $1,000 to the lesser of $50,000 or 50% of the vested 401(k) account balance (excludes Company contributions invested in NBT Bancorp Inc. common stock). Beginning January 1, 1997, participants are not allowed to borrow from employer contributions made subsequent to that date. Loans, other than loans for the purchase of a primary residence, must be repaid over a period no longer than five years. Loans for the purchase of a primary residence must be repaid over a period no longer than 15 years. Interest is charged at the prime rate plus 1%. Participant loans are treated as a transfer from the participant directed accounts into the loan fund. Principal and interest payments on the loans are allocated to the loan fund and transferred into the participant directed accounts based on the participants' current investment allocation elections. 7 NBT BANCORP INC. 401(K) AND EMPLOYEE STOCK OWNERSHIP PLAN Notes to Financial Statements December 31, 2002 and 2001 (k) ADMINISTRATIVE EXPENSES Expenses of operating and administering the Plan are generally borne by the Sponsor. The payment of these expenses is not mandated by the Plan and is done so at the discretion of the Sponsor. (l) VOTING RIGHTS With respect to participant account balances that are invested in shares of the Sponsor's stock, each participant is entitled to exercise voting rights attributable to the shares allocated to his or her account and is notified by the Trustee prior to the time that such rights are to be exercised. (m) RISKS AND UNCERTAINTIES The Plan invests in various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statement of net assets available for benefits. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) BASIS OF PRESENTATION The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America on the accrual basis of accounting. Amounts in the prior year's financial statements are reclassified when necessary to conform with the current year's presentation. (b) INVESTMENTS HELD IN TRUST Mutual funds and the common stock of the Sponsor are stated at fair value, based on published market quotations. Money market funds are short-term investments carried at cost, which approximates fair value. Loans to participants are carried at the unpaid principal balance, which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. (c) USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the use of estimates and assumptions that affect the reported amounts of net assets and changes therein. Actual results could differ from those estimates. 8 NBT BANCORP INC. 401(K) AND EMPLOYEE STOCK OWNERSHIP PLAN Notes to Financial Statements December 31, 2002 and 2001 (3) INVESTMENTS Investments that represent 5% or more of the net assets available for plan benefits at December 31, 2002 or 2001 are as follows: 2002 2001 ---------- ---------- Cash and cash equivalents: Cash $ -- 8,751,808 Strong Money Market Fund 3,184,973 2,034,887 Mutual funds: Strong Growth and Income Fund 2,697,056 -- Strong Large Cap Growth Fund 2,540,705 -- Common stock: NBT Bancorp Inc. 22,405,306 17,380,335 During 2002 and 2001, the Plan's investments (including bought, sold, and held during the year) appreciated (depreciated) in value as follows: YEAR ENDED DECEMBER 31 ------------------------- 2002 2001 ------------ ----------- Investments at fair value as determined by quoted market price: Bond mutual funds $ 25,149 4,415 Common stock of NBT Bancorp Inc. 3,318,952 (595,762) Equity mutual funds (2,673,226) (1,687,575) Foreign equity mutual funds (489,241) (457,713) ------------ ----------- $ 181,634 (2,736,635) ============ =========== (4) NONPARTICIPANT DIRECTED INVESTMENTS Information about the investments relating to accumulated nonparticipant directed contributions is as follows: DECEMBER 31 ----------------------- 2002 2001 ----------- ---------- Discretionary employer accumulated contributions invested in NBT common stock $15,508,176 14,615,734 Nondiscretionary employer accumulated contributions invested in NBT common stock 3,623,194 1,372,996 ----------- ---------- $19,131,370 15,988,730 =========== ========== 9 Information about the significant components of the changes in investments related to accumulated nonparticipant directed contributions for 2002 and 2001 is as follows: 2002 2001 ------------ ----------- Transfers from other plans $ 1,390,331 3,623,847 Contributions and loan repayments 1,015,686 564,817 Interest and dividends 806,386 768,151 Net realized and unrealized depreciation 3,189,643 (131,384) Distributions and new loans issued (3,259,406) (2,218,798) ------------ ----------- $ 3,142,640 2,606,633 ============ =========== (5) INCOME TAX STATUS The Internal Revenue Service has determined and informed the Sponsor by a letter dated October 30, 2001, that the Plan and underlying trust, as then designed, were in compliance with the applicable requirements of the Internal Revenue Code and therefore the Plan is exempt from income taxes. Management believes that the Plan is currently being operated in compliance with the applicable requirements of the Internal Revenue Code. (6) PARTY-IN-INTEREST TRANSACTIONS Certain Plan investments are shares of NBT Bancorp Inc., the Plan's Sponsor. Therefore, transactions involving those shares are party-in-interest transactions.
