                          INDEPENDENT AUDITORS' REPORT


Plan Administrator
NBT Bancorp Inc. 401(k) and Employee
   Stock Ownership Plan:


We have audited the accompanying statements of net assets available for plan
benefits of NBT Bancorp Inc. 401(k) and Employee Stock Ownership Plan as of
December 31, 2002 and 2001 and the related statements of changes in net assets
available for plan benefits for the years then ended. 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.

                          Notes to Financial Statements

                           December 31, 2002 and 2001


(1)  DESCRIPTION  OF  PLAN

     The following description of the NBT Bancorp Inc. 401(k) and Employee Stock
     Ownership  Plan  (the  Plan)  is  provided for general information purposes
     only.  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.

                           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:

     (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.

                          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.

                           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.

(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.  Additionally,  the trustee of the Plan is
     NBT  Bank,  N.A.  which  is  a  subsidiary  of  the  Sponsor.
