streamlining  operational  processes, and internal growth. During 2001 and 2000,
the  Company  expanded the breadth of its market area by acquiring other banking
organizations  and  select  niche financial services companies. In addition, the
Company  has  selectively  opened  key  new  businesses  that expand our product

March  16,  2001,  Pennstar  Bank,  N.A.  was  merged  into  the  Bank.


COMPETITION

The  banking  and  financial  services  industry  in  New  York and Pennsylvania
generally,  and  in  the  Company's  market  areas  specifically,  is  highly
competitive.  The  increasingly competitive environment is a result primarily of
changes  in  regulation,  changes  in  technology  and product delivery systems,
additional  financial  service  providers,  and  the  accelerating  pace  of
consolidation among financial services providers. The Company competes for loans
and  leases,  deposits,  and  customers with other commercial banks, savings and
loan  associations,  securities  and  brokerage  companies,  mortgage companies,
insurance  companies,  finance companies, money market funds, credit unions, and
other  nonbank  financial  service providers. Many of these competitors are much
larger  in  total  assets  and  capitalization,  have  greater access to capital
markets  and  offer  a  broader range of financial services than the Company. In
order  to  compete with other financial services providers, the Company stresses
the community nature of its banking operations and principally relies upon local
promotional  activities,  personal  relationships  established  by  officers,
directors, and employees with their customers, and specialized services tailored
to  meet  the  needs  of  the  communities  served.


SUPERVISION  AND  REGULATION

As  a  bank  holding  company,  the  Company is subject to extensive regulation,
supervision,  and  examination  by the Board of Governors of the Federal Reserve
System ("FRS") as its primary federal regulator. The Company also has elected to
be  registered  with  the  FRS  as  a  financial holding company. The Bank, as a
nationally  chartered  bank, is subject to extensive regulation, supervision and
examination  by  the  Office  of  the Comptroller of the Currency ("OCC") as its
primary federal regulator and, as to certain matters, by the FRS and the Federal
Deposit  Insurance  Corporation  ("FDIC").

     M.  Griffith,  Inc. ("MGI") is registered as a broker-dealer and investment
adviser  and  is subject to extensive regulation, supervision and examination by
the  Securities  and  Exchange  Commission  ("SEC"). MGI is also a member of the
National  Association of Securities Dealers, Inc. ("NASD") and is subject to its
regulations.  MGI  is  authorized  as  well  to  engage as a broker, dealer, and
underwriter of municipal securities, and as such is subject to regulation by the
Municipal  Securities  Rulemaking Board. In addition, MGI and Colonial Financial
Services, Inc., are licensed insurance agencies with offices in the state of New
York  and  are  subject  to  registration  and supervision by the New York State
Insurance  Department. Pennstar Financial Services, Inc. is a licensed insurance
agency  with  offices  in  the  Commonwealth  of  Pennsylvania and is subject to
registration  and  supervision  by  the  Pennsylvania  Insurance  Department.


6                                                ANNUAL REPORT: NBT BANCORP INC.

     The  Company  is  subject  to  capital  adequacy guidelines of the FRS. The
guidelines  apply  on a consolidated basis and require bank holding companies to
maintain a minimum ratio of Tier 1 capital to total average assets (or "leverage
ratio")  of  4%.  For  the most highly rated bank holding companies, the minimum
ratio  is  3%.  The  FRS  capital  adequacy guidelines also require bank holding
companies  to maintain a minimum ratio of Tier 1 capital to risk-weighted assets
of 4% and a minimum ratio of qualifying total capital to risk-weighted assets of
8%.  As  of December 31, 2002, the Company's leverage ratio was 6.73%, its ratio
of Tier 1 capital to risk-weighted assets was 9.93%, and its ratio of qualifying
total capital to risk-weighted assets was 11.18%. The FRS may set higher minimum
capital  requirements for bank holding companies whose circumstances warrant it,
such  as  companies anticipating significant growth or facing unusual risks. The
FRS has not advised the Company of any special capital requirement applicable to
it.

     Any  holding  company  whose  capital  does  not  meet  the minimum capital
adequacy  guidelines  is  considered  to  be undercapitalized and is required to
submit  an  acceptable  plan  to  the FRS for achieving capital adequacy. Such a
company's  ability  to pay dividends to its shareholders and expand its lines of
business  through the acquisition of new banking or nonbanking subsidiaries also
could  be  restricted.

     The  Bank  is  subject  to leverage and risk-based capital requirements and
minimum  capital  guidelines  of the OCC that are similar to those applicable to
the  Company.  As  of  December  31,  2002,  the Bank was in compliance with all
minimum  capital requirements. The Bank's leverage ratio was 6.62%, its ratio of
Tier  1  capital  to risk-weighted assets was 9.86%, and its ratio of qualifying
total  capital  to  risk-weighted  assets  was  11.12%.

     Under  FDIC  regulations, no FDIC-insured bank can accept brokered deposits
unless  it  is  well  capitalized,  or  is adequately capitalized and receives a
waiver  from  the FDIC. In addition, these regulations prohibit any bank that is
not well capitalized from paying an interest rate on brokered deposits in excess
of  three-quarters of one percentage point over certain prevailing market rates.
As  of  December  31,  2002,  the  total amount of brokered deposits were $150.0
million.

     The  Bank  also  is  subject  to substantial regulatory restrictions on its
ability to pay dividends to the Company. Under OCC regulations, the Bank may not
pay a dividend, without prior OCC approval, if the total amount of all dividends
declared  during  the calendar year, including the proposed dividend, exceed the
sum of its retained net income to date during the calendar year and its retained
net  income over the preceding two years. As of December 31, 2002, approximately
$9.8  million  was  available  for  the  payment  of dividends without prior OCC
approval.  The Bank's ability to pay dividends also is subject to the Bank being
in  compliance  with  regulatory  capital requirements. The Bank is currently in
compliance  with  these  requirements.

     The  deposits  of  the Bank are insured up to regulatory limits by the FDIC
and,  accordingly,  are subject to deposit insurance assessments to maintain the
insurance  funds administered by the FDIC. The deposits of the Bank historically
have  been  subject  to  deposit  insurance  assessments  to  maintain  the Bank
Insurance  Fund  ("BIF"). Due to certain branch deposit acquisitions by the Bank
and  its  predecessors,  some of the deposits of the Bank are subject to deposit
insurance  assessments  to  maintain  the  Savings  Association  Insurance  Fund
("SAIF").

     The  FDIC  has  adopted  regulations  establishing a permanent risk-related
deposit  insurance  assessment  system.  Under this system, the FDIC places each
insured  bank  in one of nine risk categories based on the bank's capitalization
and  supervisory  evaluations  provided to the FDIC by the institution's primary
federal  regulator.  Each  insured  bank's  insurance  assessment  rate  is then
determined by the risk category in which it is classified by the FDIC.

     In  the  light  of the then prevailing favorable financial situation of the
federal  deposit  insurance  funds  and the low number of depository institution
failures,  since January 1, 1997, the annual insurance premiums on bank deposits
insured  by  the  BIF or the SAIF have varied between $0.00 per $100 of deposits
for  banks  classified  in  the  highest  capital  and  supervisory  evaluation
categories  to  $0.27  per  $100  of deposits for banks classified in the lowest
capital and supervisory evaluation categories. Recent increases in the amount of
deposits  subject  to  BIF  FDIC  insurance protection and in the number of bank
failures,  and the effect of low interest rate returns on the assets held in the
BIF,  have  increased  the likelihood that the annual insurance premiums on bank
deposits  insured  by  the  BIF  will  increase  in  the  second half of 2003 or
thereafter.  BIF and SAIF assessment rates are subject to semi-annual adjustment
by  the  FDIC  within a range of up to five basis points without public comment.
The  FDIC  also  possesses  authority to impose special assessments from time to
time.

     The Federal Deposit Insurance Act provides for additional assessments to be
imposed  on  insured  depository  institutions  to pay for the cost of Financing
Corporation  ("FICO")  funding.  The  FICO assessments are adjusted quarterly to
reflect  changes  in the assessment bases of the FDIC insurance funds and do not
vary  depending  upon  a


ANNUAL REPORT: NBT BANCORP INC.                                               7

depository  institution's capitalization or supervisory evaluation. During 2002,
FDIC-insured  banks  paid  an  average rate of approximately $0.017 per $100 for
purposes of funding FICO bond obligations. The assessment rate has been retained
at this rate for the first and second quarters of 2003.

     Transactions  between  the  Bank  and  any of its affiliates, including the
Company,  are  governed  by  sections 23A and 23B of the Federal Reserve Act. An
"affiliate"  of a bank is any company or entity that controls, is controlled by,
or  is  under  common  control with the bank. A subsidiary of a bank that is not
also  a  depository  institution  is not treated as an affiliate of the bank for
purposes  of  sections  23A  and  23B,  unless the subsidiary is also controlled
through  a non-bank chain of ownership by affiliates or controlling shareholders
of the bank or the subsidiary engages in activities that are not permissible for
a  bank to engage in directly (except insurance agency subsidiaries). Generally,
sections  23A  and  23B  are intended to protect insured depository institutions
from  suffering losses arising from transactions with non-insured affiliates, by
limiting  the  extent  to which a bank or its subsidiaries may engage in covered
transactions  with  any one affiliate and with all affiliates of the bank in the
aggregate,  and requiring that such transactions be on terms that are consistent
with  safe  and  sound  banking  practices.

     On  October  31,  2002,  the  FRS  adopted  a new regulation, Regulation W,
effective  April  1, 2003, that comprehensively implements sections 23A and 23B.
The  regulation unifies and updates staff interpretations issued over the years,
incorporates  several  new  interpretative  proposals  (such  as to clarify when
transactions  with an unrelated third party will be attributed to an affiliate),
and addresses new issues arising as a result of the expanded scope of nonbanking
activities  engaged  in  by banks and bank holding companies in recent years and
authorized  for  financial  holding  companies  under the Gramm-Leach-Bliley Act
("GLB  Act").

     Under  the GLB Act, a qualifying bank holding company, known as a financial
holding  company, may engage in certain financial activities that a bank holding
company  may  not  otherwise  engage in under the Bank Holding Company Act ("BHC
Act").  In  addition  to  engaging  in banking and activities closely related to
banking  as  determined  by the FRS by regulation or order prior to November 11,
1999, a financial holding company may engage in activities that are financial in
nature  or  incidental  to  financial  activities,  or  activities  that  are
complementary  to a financial activity and do not pose a substantial risk to the
safety  and  soundness  of  depository  institutions  or  the  financial  system
generally.

     Under  the  GLB  Act, all financial institutions, including the Company and
the  Bank,  are  required  to  adopt  privacy  policies, restrict the sharing of
nonpublic  customer  data  with nonaffiliated parties at the customer's request,
and  establish  procedures  and  practices  to  protect  customer  data  from
unauthorized  access.

     Under  Title  III  of  the USA PATRIOT Act, also known as the International
Money  Laundering  Abatement  and  Anti-Terrorism  Financing  Act  of  2001, all
financial  institutions,  including  the  Company  and the Bank, are required in
general  to  identify their customers, adopt formal and comprehensive anti-money
laundering  programs,  scrutinize or prohibit altogether certain transactions of
special  concern,  and  be  prepared  to  respond  to  inquiries  from  U.S. law
enforcement  agencies  concerning  their  customers  and  their  transactions.
Additional information- sharing among financial institution, regulators, and law
enforcement  authorities  is encouraged by the presence of an exemption from the
privacy  provisions  of  the GLB Act for financial institutions that comply with
this  provision  and the authorization of the Secretary of the Treasury to adopt
rules  to  further  encourage  cooperation  and  information-sharing.  The
effectiveness  of  a  financial  institution  in  combating  money  laundering
activities  is  a  factor  to  be considered in any application submitted by the
financial  institution  under the Bank Merger Act, which applies to the Bank, or
the  BHC  Act,  which  applies  to  the  Company.

     The  Sarbanes-Oxley  Act,  signed  into law July 30, 2002, addresses, among
other  issues,  corporate  governance,  auditor  independence  and  accounting
standards,  executive compensation, insider loans, whistleblower protection, and
enhanced  and timely disclosure of corporate information. The SEC has adopted or
proposed  several  implementing  rules,  and  the  NASD  has  proposed corporate
governance  rules  that  have been presented to the SEC for review and approval.
The  proposed  changes  are  intended  to  allow  stockholders  to  monitor more
effectively  the  performance  of  companies  and  management.

     Effective  August  29,  2002,  as  directed  by  section  302(a)  of  the
Sarbanes-Oxley  Act,  the  Company's chief executive officer and chief financial
officer  are  each  required  to certify that the Company's quarterly and annual
reports do not contain any untrue statement of a material fact. This requirement
has  several  parts, including certification that these officers are responsible
for  establishing, maintaining and regularly evaluating the effectiveness of the
Company's  internal  controls;  that  they  have made certain disclosures to the
Company's  auditors  and the risk management committee of the board of directors
about  the  Company's  internal  controls;  and  that  they  have  in-

cluded  information  in  the  Company's quarterly and annual reports about their
evaluation  and  whether  there  have  been significant changes in the Company's
internal  controls  or in other factors that could significantly affect internal
controls  subsequent  to  the  evaluation.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND  RESULTS
OF  OPERATIONS
- --------------------------------------------------------------------------------

GENERAL

The  financial  review  which  follows  focuses  on  the  factors  affecting the
consolidated  financial  condition and results of operations of NBT Bancorp Inc.
(the "Registrant" or the "Company") and its wholly owned subsidiaries, NBT Bank,
N.A.  ("the  Bank"),  NBT  Financial  Services,  Inc. ("NBT Financial), and CNBF
Capital  Trust  I  during  2002  and,  in summary form, the preceding two years.
Collectively, the Registrant and its subsidiaries are referred to herein as "the
Company." Net interest margin is presented in this discussion on a fully taxable
equivalent  (FTE)  basis.  Average  balances discussed are daily averages unless
otherwise  described.  The audited consolidated financial statements and related
notes  as  of  December 31, 2002 and 2001 and for each of the years in the three
year  period  ended  December  31,  2002 should be read in conjunction with this
review.  Amounts  in  prior  period  consolidated  financial  statements  are
reclassified  whenever  necessary  to  conform  to  the  2002  presentation.

     The  preparation  of  the  consolidated  financial  statements  requires
management  to  make  estimates  and  assumptions, in the application of certain
accounting  policies, about the effect of matters that are inherently uncertain.
Those  estimates  and assumptions affect the reported amounts of certain assets,
liabilities,  revenues  and  expenses. Different amounts could be reported under
different  conditions,  or if different assumptions were used in the application
of  these  accounting  policies.

     The  business  of the Company is providing commercial banking and financial
services  through its subsidiaries. The Company's primary market area is central
and  upstate  New  York and northeastern Pennsylvania. The Company has been, and
intends to continue to be, a community-oriented financial institution offering a
variety  of  financial  services. The Company's principle business is attracting
deposits  from  customers  within  its  market  area  and  investing those funds
primarily  in  loans  and  leases,  and,  to  a  lesser  extent,  in  marketable
securities.  The  financial  condition  and operating results of the Company are
dependent  on  its  net  interest  income  which  is  the difference between the
interest  and  dividend  income  earned  on  its earning assets and the interest
expense  paid  on  its  interest  bearing  liabilities,  primarily consisting of


12                                               ANNUAL REPORT: NBT BANCORP INC.

deposits  and borrowings. Net income is also affected by provisions for loan and
lease  losses  and  noninterest  income,  such  as  service  charges  on deposit
accounts,  broker/dealer fees, trust fees, and gains/losses on securities sales;
it  is  also  impacted  by  noninterest  expense,  such as salaries and employee
benefits,  data  processing,  communications,  occupancy,  and  equipment.

     The  Company's  results of operations are significantly affected by general
economic  and  competitive  conditions  (particularly changes in market interest
rates),  government  policies,  changes  in accounting standards, and actions of
regulatory  agencies.  Future  changes  in  applicable  laws,  regulations,  or
government  policies  may  have  a  material  impact  on  the  Company.  Lending
activities are substantially influenced by the demand for and supply of housing,
competition  among  lenders, the level of interest rates, the state of the local
and  regional  economy,  and  the  availability  of funds. The ability to gather
deposits  and  the  cost  of  funds are influenced by prevailing market interest
rates,  fees  and  terms  on  deposit  products,  as well as the availability of
alternative  investments  including  mutual  funds  and  stocks.


CRITICAL  ACCOUNTING  POLICIES

Management  of  the  Company  considers  the  accounting  policy relating to the
allowance for loan and lease losses to be a critical accounting policy given the
uncertainty  in  evaluating  the level of the allowance required to cover credit
losses  inherent  in  the  loan and lease portfolio and the material effect that
such judgments can have on the results of operations. While management's current
evaluation  of  the  allowance  for  loan  and  lease  losses indicates that the
allowance  is adequate, under adversely different conditions or assumptions, the
allowance  would need to be increased. For example, if historical loan and lease
loss  experience  significantly  worsened  or  if  current  economic  conditions
significantly  deteriorated,  additional  provisions  for  loan and lease losses
would  be  required  to increase the allowance. In addition, the assumptions and
estimates used in the internal reviews of the Company's non-performing loans and
potential  problem loans has a significant impact on the overall analysis of the
adequacy  of  the  allowance  for  loan  and  lease losses. While management has
concluded  that  the current evaluation of collateral values is reasonable under
the  circumstances,  if  collateral  evaluations were significantly lowered, the
Company's  allowance  for  loan  and  lease policy would also require additional
provisions  for  loan  and  lease  losses.

     The  Company's  policy  on  the  allowance  for  loan  and  lease losses is
disclosed  in  note  1 to the consolidated financial statements. A more detailed
description  of the allowance for loan and lease losses is included in the "Risk
Management"  section  of  this Form 10-K. All accounting policies are important,
and  as  such,  the Company encourages the reader to review each of the policies
included  in  note  1  to  obtain  a  better  understanding on how the Company's
financial  performance  is  reported.


FORWARD  LOOKING  STATEMENTS

Certain  statements  in  this  filing and future filings by the Company with the
Securities  and  Exchange  Commission,  in the Company's press releases or other
public  or  shareholder  communications,  or  in  oral  statements made with the
approval of an authorized executive officer, contain forward-looking statements,
as defined in the Private Securities Litigation Reform Act. These statements may
be  identified  by the use of phrases such as "anticipate," "believe," "expect,"
"forecasts,"  "projects,"  "will,"  "can," "would," "should," "could," "may," or
other similar terms. There are a number of factors, many of which are beyond the
Company's  control  that  could  cause  actual results to differ materially from
those  contemplated  by  the  forward looking statements. Factors that may cause
actual  results  to  differ  materially  from  those  contemplated  by  such
forward-looking  statements  include, among others, the following possibilities:
(1)  competitive pressures among depository and other financial institutions may
increase  significantly; (2) revenues may be lower than expected; (3) changes in
the  interest rate environment may reduce interest margins; (4) general economic
conditions,  either  nationally  or  regionally,  may  be  less  favorable  than
expected,  resulting  in,  among other things, a deterioration in credit quality
and/or  a  reduced  demand  for  credit;  (5) legislative or regulatory changes,
including  changes  in accounting standards or tax laws may adversely affect the
businesses in which the Company is engaged; (6) costs or difficulties related to
the  integration of the businesses of the Company and its merger partners may be
greater  than  expected  (7)  deposit  attrition, customer loss, or revenue loss
following  recent  mergers  and  acquisitions  may be greater than expected; (8)
competitors  may  have  greater  financial  resources  and develop products that
enable  such  competitors to compete more successfully than the Company; and (9)
adverse  changes  may  occur  in  the  securities  markets  or  with  respect to
inflation.

     The  Company  cautions  readers  not  to  place  undue  reliance  on  any
forward-looking  statements, which speak only as of the date made, and to advise
readers  that  various  factors,  including  but  not limited to those described
above,  could  affect  the  Company's  financial  performance


ANNUAL REPORT: NBT BANCORP INC.                                               13

and could cause the Company's actual results or circumstances for future periods
to  differ  materially  from  those  anticipated  or  projected.

     Except as required by law, the Company does not undertake, and specifically
disclaims any obligations to, publicly release any revisions that may be made to
any  forward-looking  statements  to  reflect  statements  to  the occurrence of
anticipated  or  unanticipated  events  or  circumstances after the date of such
statements.

MERGER AND ACQUISITION ACTIVITY

The Company did not enter into any merger or acquisitions during 2002.

     On  June  1,  2001, the Company completed the acquisition of First National
Bancorp,  Inc.  (FNB)  whereby  FNB was merged with and into the Company. At the
same  time FNB's subsidiary, First National Bank of Northern New York (FNB Bank)
was  merged  into the Bank. The acquisition was accounted for using the purchase
method.  As  such, both the assets and liabilities assumed have been recorded on
the  consolidated balance sheet of the Company at estimated fair value as of the
date  of acquisition and the results of operations are included in the Company's
consolidated  statement of income from the acquisition date forward. To complete
the transaction, the Company issued approximately 1,075,000 shares of its common
stock  valued  at $16.0 million. Goodwill, representing the cost over net assets
acquired,  was  approximately  $7.0 million and was being amortized prior to the
adoption  of  Statement  of  Financial  Accounting  Standards  (SFAS) No. 142 on
January 1, 2002 on a straight-line basis based on a 20 year amortization period.

     On  September 14, 2001, the Company acquired $14.4 million in deposits from
Mohawk  Community  Bank.  Unidentified  intangible  assets,  accounted  for  in
accordance  with SFAS No. 72 and representing the excess of cost over net assets
acquired,  was  $0.7  million  and  is  being  amortized  over  15  years  on  a
straight-line  basis.  Additionally, the Company identified $0.1 million of core
deposit  intangible  assets  which  is  being  amortized  over  6  years  on  a
straight-line  basis.

     On November 8, 2001, the Company, pursuant to a merger agreement dated June
18,  2001,  completed  its  merger with CNB Financial Corp. (CNB) and its wholly
owned  subsidiary, Central National Bank (CNB Bank), whereby CNB was merged with
and  into  the Company, and CNB Bank was merged with and into the Bank. CNB Bank
then  became  a  division  of  the  Bank.  In  connection  with  the merger, CNB
stockholders received 1.2 shares of the Company's common stock for each share of
CNB  stock  and  the  Company  issued approximately 8.9 million shares of common
stock.  The  transaction is structured to be tax-free to shareholders of CNB and
has  been  accounted  for  as a pooling-of-interests. Accordingly, the Company's
consolidated financial statements were restated to present combined consolidated
financial  condition  and  results  of  operations of the Bank and CNB as if the
merger  had  been  in effect for all years presented. At September 30, 2001, CNB
had consolidated assets of $983.1 million, deposits of $853.7 million and equity
of  $62.8  million.  CNB  Bank  operated 29 full service banking offices in nine
upstate  New  York  counties.

     On  February  17,  2000,  the  Company completed its merger with Lake Ariel
Bancorp,  Inc.  (Lake Ariel) and its subsidiaries. In connection with the merger
each  issued  and outstanding share of Lake Ariel exchanged for 0.9961 shares of
the  Company's  common  stock.  The  transaction  resulted  in  the  issuance of
approximately  5.0  million  shares  of  Company's  common  stock.  Lake Ariel's
commercial  banking  subsidiary  was  LA  Bank,  N.A.

     On  July  1,  2000,  the Company completed its merger with Pioneer American
Holding  Company  Corp.  (Pioneer  Holding  Company)  and  its  subsidiary.  In
connection with the merger, each issued and outstanding share of Pioneer Holding
Company  exchanged  for  1.805  shares  of  the  Company's  common  stock.  The
transaction  resulted in the issuance of approximately 5.2 million shares of the
Company's  common stock. Pioneer Holding Company's commercial banking subsidiary
was  Pioneer  American  Bank,  N.A.

     The  Lake  Ariel  and Pioneer Holding Company mergers qualified as tax-free
exchanges  and  were  accounted  for  as poolings-of-interests. Accordingly, the
Company's  consolidated  financial  statements  were  restated  to  present  the
combined  consolidated  financial  condition  and  results  of operations of all
companies  as  if  the  mergers  had  been  in  effect  for all years presented.

     LA  Bank, N.A. and Pioneer Bank N.A. were commercial banks headquartered in
northeastern  Pennsylvania  with  approximately  $570  million and $420 million,
respectively, in assets at December 31, 1999, and twenty-two and eighteen branch
offices,  respectively,  in  five counties. Immediately following the Lake Ariel
and  Pioneer  Holding  Company  mergers  described  above,  the  Company was the
surviving  holding  company  for NBT Bank, LA Bank, N.A., Pioneer American Bank,
N.A.  and  NBT  Financial  Services,  Inc.  On  November 10, 2000, LA Bank, N.A.
changed  its  name to Pennstar. On December 9, 2000, Pioneer American Bank, N.A.
was  merged  into Pennstar. On March 16, 2001, Pennstar was merged with and into
the  Bank  and  became  a  division  of  the  Bank.


14                                               ANNUAL REPORT: NBT BANCORP INC.

     On  May  5,  2000,  the Company consummated the acquisition of M. Griffith,
Inc.  a  Utica,  New  York  based securities firm offering investment, financial
advisory  and  asset-management services, primarily in the Mohawk Valley region.
At  that  time, M. Griffith, Inc., a full-service broker/dealer and a Registered
Investment  Advisor,  became  a  wholly-owned  subsidiary  of NBT Financial. The
acquisition  was  accounted  for  using  the  purchase method. As such, both the
assets  acquired  and liabilities assumed have been recorded on the consolidated
balance  sheet  of  the  Company  at  estimated  fair  value  as  of the date of
acquisition.  M.  Griffith,  Inc.'s,  results  of operations are included in the
Company's consolidated statement of income from the date of acquisition forward.
To  complete the transaction, the Company issued approximately 421,000 shares of
its  common  stock, valued at $4.8 million. Goodwill, representing the cost over
net  assets  acquired,  was  $3.4  million  and was being amortized prior to the
adoption  of  SFAS  No.  142  on  January  1,  2002  over  fifteen  years  on  a
straight-line  basis.

     On  June  2,  2000,  Pennstar,  purchased  two  branches  from Mellon Bank.
Deposits  from  the  Mellon  Bank  branches  were  approximately  $36.7 million,
including  accrued  interest  payable.  In  addition,  the  Company  received
approximately  $32.2  million  in  cash  as  consideration  for  net liabilities
assumed.  The  acquisition was accounted for using the purchase method. As such,
both  the  assets  acquired  and  liabilities  assumed have been recorded on the
consolidated balance sheet of the Company at estimated fair value as of the date
of  the acquisition. Unidentified intangible assets, accounted for in accordance
with  SFAS No. 72, and representing the excess of cost over net assets acquired,
was  $4.3  million and was being amortized prior to the adoption of SFAS No. 147
on  January  1,  2002  over  15  years on the straight-line basis. The branches'
results  of  operations  are included in the Company's consolidated statement of
income  from  the  date  of  acquisition  forward.

     On  November 10, 2000, Pennstar purchased six branches from Sovereign Bank.
Deposits  from  the  Soverign  Bank  branches  were approximately $96.8 million,
including  accrued  interest  payable.  Pennstar also purchased commercial loans
associated  with  the  branches  with  a  net  book balance of $42.4 million. In
addition,  the  Company  received  $40.9  million  in cash consideration for net
liabilities  assumed.  The  acquisition  was  accounted  for  using the purchase
method.  As  such,  both  the  assets acquired and liabilities assumed have been
recorded  on  the  consolidated  balance  sheet of the Company at estimated fair
value  as  of  the  date  of  the  acquisition.  Unidentified intangible assets,
accounted  for  in  accordance  with SFAS No. 72, and representing the excess of
cost  over  net assets acquired, was $12.7 million and was being amortized prior
to  the  adoption  of  SFAS  No.  147  on  January  1,  2002  over 15 years on a
straight-line  basis.  The  branches'  results of operations are included in the

     As  of  December 31, 2002, the Company had a remaining accrued liability of
$4.0  million  for  merger,  acquisition, and reorganization costs recognized in
2001  and 2000. The remaining accrued liability is comprised mainly of severance
costs,  which  will be paid out over a period of time consistent with respective
severance  agreements.


OVERVIEW

The Company had net income of $45.0 million or $1.35 per diluted share for 2002,
compared  to net income of $3.7 million or $0.11 per diluted share for 2001. The
improvement  in  2002  results over 2001 was due to several factors. There was a
$22.9  million decrease in the provision for loan and lease losses when compared
to  the  same  period  in  2001. The increase in the 2001 provision for loan and
lease  losses  was  due  mainly  to  an  increase  in  nonperforming  loans  and
charge-offs  during 2001, resulting mainly from the process of integrating loans
from recently acquired banks and weakening business conditions. The net interest
margin  improved  during  2002,  resulting  in  a  $8.9  million increase in net
interest  income over 2001. Noninterest income was up $8.3 million for 2002 when
compared  to 2001. Driving this increase was a decrease in net securities losses
of  $7.3 million in 2002 when compared to 2001, due to the sale and writedown of
several  high-risk  securities  previously  held  by  CNB


ANNUAL REPORT: NBT BANCORP INC.                                               15

during  2001. Additionally, growth in noninterest income from service charges on
deposit  accounts  and broker/ dealer and insurance revenue totaled $2.4 million
in  2002 compared to 2001. Offsetting these increases was a $1.4 million gain on
a  sale  of  a  branch  building  in  2001  compared  to  no  such gain in 2002.
Noninterest expenses were down $22.5 million in 2002 when compared to 2001. This
decrease  was  driven  primarily  by  three  factors.  First, there was a slight
recovery  of  merger  costs of $0.1 million in 2002 compared to $15.3 million in
merger  charges  in  2001  that  resulted primarily from the acquisition of CNB.
Second,  the  stabilization of residual values of leased automobiles resulted in
no  provision  for  the  other-than-temporary  impairment  in residual values of
leased automobiles in 2002 compared to a $3.5 million provision in 2001. Lastly,
because  of accounting standards that became effective for the Company in fiscal
year 2002, amortization of goodwill and intangible assets decreased $3.5 million
in 2002. If these accounting standards had been applied in 2001, the decrease in
the  amortization  of  goodwill  and  intangible  assets  would increase diluted
earnings  per  share  by  $0.07  in  2001.

     The  Company  had net income of $3.7 million or $0.11 per diluted share for
2001,  compared  to  net  income of $14.2 million or $0.44 per diluted share for
2000.  During  2001,  costs  related  to  merger, acquisition and reorganization
activities  totaled $15.3 million and net securities losses totaled $7.7 million
compared  to  $23.6  million  related  to merger, acquisition and reorganization
activities  and $2.3 million in net securities loss in 2000. Net interest income
for  2001  increased  8.3% to $137.9 million compared to $127.4 million in 2000.
Net  interest  income  for 2001 was up $10.6 million over 2000 as a result of an
improved net interest margin combined with growth in the average loan portfolio.
Noninterest income for 2001 was up $1.6 million over 2000. Net securities losses
for 2001 and 2000 totaled $7.7 million and $2.3 million, respectively. Excluding
these net securities losses, other components of noninterest income were up $7.0
million  in 2001 when compared to 2000. A gain on the sale of a branch building,
service  charges on deposit accounts, ATM fees, banking fees, broker/dealer fees
and  insurance commissions drove the increase in noninterest income in 2001 over
2000. Noninterest expense was up $6.7 million in 2001 when compared to 2000. The
increase  in  non-interest expense resulted from a $3.5 million charge taken for
the  other-than-temporary impairment of the residual value of leased automobiles
compared  to  a  charge of $0.7 million in 2000, a $2.1 million charge taken for
certain  deposit  overdrafts,  and a $10.0 million increase in expense primarily
related  to  the  required  service  and support of our growth. Offsetting these
increases  was  a  decrease  in merger, acquisition, and reorganization costs of
$8.3  million.


ASSET/LIABILITY  MANAGEMENT

The  Company  attempts  to  maximize  net interest income, and net income, while
actively managing its liquidity and interest rate sensitivity through the mix of
various  core deposit products and other sources of funds, which in turn fund an
appropriate  mix  of  earning assets. The changes in the Company's asset mix and
sources  of  funds,  and the resultant impact on net interest income, on a fully
tax  equivalent  basis,  are  discussed  below.

     The  following  table  includes  the condensed consolidated average balance
sheet,  an  analysis  of interest income/expense and average yield/rate for each
major  category  of earning assets and interest bearing liabilities on a taxable
equivalent basis. Interest income for tax-exempt securities and loans and leases
has  been  adjusted  to  a  taxable-equivalent basis using the statutory Federal
income  tax  rate  of  35%.

NET INTEREST INCOME

On a tax equivalent basis, the Company's net interest income for 2002 was $151.1
million,  up  from  $141.8  million  for 2001. The Company's net interest margin
improved  to 4.43% for 2002 from 4.19% for 2001. The improvement in net interest
income  and  net  interest  margin  in 2002 were due primarily to three factors.
First,  the  Company  benefited from the decreasing rate environment in 2002, as
interest-bearing  liabilities  repriced  downward  at a faster rate than earning
assets. Secondly, there was a slight increase in average earning assets of $26.0
million or 1%, in 2002 when compared to 2001, driven primarily by loan and lease
growth.  Lastly, an improved deposit mix lowered interest expense, as lower cost
NOWs,  money  market,  and  savings  accounts  comprised  39%  of  average total
interest-bearing  liabilities  in  2002  compared  to  36%  in  2001.

     The  following  table  presents changes in interest income, on a FTE basis,
and  interest  expense  attributable  to  changes  in  volume (change in average
balance  multiplied  by  prior  year  rate),  changes  in  rate  (change in rate
multiplied by prior year volume), and the net change in net interest income. The
net  change  attributable  to  the  combined  impact of volume and rate has been
allocated  to  each  in  proportion  to  the  absolute dollar amounts of change.

LOANS AND LEASES AND CORRESPONDING INTEREST AND FEES ON LOANS

The  average  balance of loans and leases increased 1%, totaling $2.3 billion in
2002  and  2001.  The  yield on average loans and leases decreased from 8.13% in
2001 to 7.18% in 2002, as a falling interest rate environment prevailed for much
of  2002.  Interest  income  from loans and leases on a FTE basis decreased 11%,
from  $188.1 million in 2001 to $167.9 million in 2002. The decrease in interest
income from loans and leases was due primarily to the decrease in yield on loans
and  leases  in  2002  of  95  bp  when  compared  to  2001.

     Total  loans  and  leases increased slightly at December 31, 2002, totaling
$2.4  billion  from  $2.3  billion  at December 31, 2001. The combination of the
Company's  focus on improving the credit quality of the loan and lease portfolio
and  sluggish  business  conditions  coupled  with  strong  competition  in  the
Company's  market  area  limited  loan  growth  opportunities for commercial and
consumer  loans  in 2002. However, residential real estate mortgages were $579.6
million  at  December  31,  2002, up $54.2 million or 10% from $525.4 million at
December  31, 2001. The increase in residential real estate mortgages was driven
primarily  by  the  historic  low  interest  rates  for  residential real estate
mortgages  which


18                                               ANNUAL REPORT: NBT BANCORP INC.

led  to an increase in demand for the product in 2002. The Company continued its
trend  of  strong growth for its home equity products. Home equity loans totaled
$269.6  million  at  December  31, 2002, up $36.9 million or 16% from the $232.6
million  outstanding  at December 31, 2001. Commercial loans and commercial real
estate  decreased  $37.7  million,  to  $920.3 million at December 31, 2002 from
$958.1  million  at  December  31,  2001.  The  decrease in commercial loans and
commercial  real  estate  was driven primarily by the Company's focus to improve
the  credit  quality  of this portfolio in 2002. Additionally, sluggish business
conditions  and strong competition in a weak market factored into the decline in
the  commercial  loan  and  real  estate  portfolio  in  2002  as  well. Lastly,
nonaccrual  commercial and agricultural loans and real estate decreased by $14.4
million,  to  $17.0  million at December 31, 2002 from $31.4 million at December
31,  2001.  Consumer loans decreased $29.9 million to $357.2 million at December
31,  2002  from  $387.1  million  at December 31, 2001. The decrease in consumer
loans  resulted  primarily from a decline in revolving personal credit and loans
secured  by  recreational  equipment  and  manufactured  housing.

     The  following  table  reflects  the  loan  and  lease  portfolio  by major
categories as of December 31 for the years indicated:

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


     Real estate mortgages consist primarily of loans secured by first or second
deeds  of trust on primary residencies. Loans in the commercial and agricultural
category,  as well as commercial and agricultural real estate mortgages, consist
primarily of short-term and/or floating rate loans made to small to medium-sized
entities.  Consumer loans consist primarily of installment credit to individuals
secured  by  automobiles  and  other  personal  property  including manufactured
housing.  Manufactured  housing loans totaled $35.5 million and $41.4 million at
December  31,  2002  and  2001,  respectively,  and were 9.9% and 10.7% of total
consumer loans at December 31, 2002 and 2001, respectively. These decreases from
2001  to  2002  are  consistent  with  the  Company's plan to de-emphasize loans
secured  by  manufactured  housing.


LEASE  FINANCING

The  Company  maintained  an automobile lease financing portfolio totaling $61.1
million  at  December  31,  2002  and  $72.0 million at December 31, 2001. Lease
receivables primarily represent automobile financing to customers through direct
financing  leases  and  are  carried  at  the  aggregate  of  the lease payments
receivable  and  the  estimated  residual values, net of unearned income and net
deferred  lease  origination fees and costs. Net deferred lease origination fees
and  costs  are amortized under the effective interest method over the estimated
lives  of  the  leases.  The estimated residual value related to the total lease
portfolio  is  reviewed  quarterly,  and  if  there  has  been  a decline in the
estimated  fair  value  of  the  residual  that  is  judged  by management to be
other-than-temporary,  a  loss  is  recognized.  Adjustments  related  to  such
other-than-temporary  declines  in  estimated fair value are recorded with other
noninterest  expenses  in the consolidated statements of income. One of the most
significant  risks  associated  with  leasing  operations is the recovery of the
residual  value  of  the leased vehicles at the termination of the lease. When a
lease  receivable  asset  is  recorded, included in this amount is the estimated
residual  value  of  the  leased  vehicle  at  the  termination of the lease. At
termination,  the  lessor has the option to purchase the vehicle or may turn the
vehicle  over  to  the  Company.


ANNUAL REPORT: NBT BANCORP INC.                                               19

     The  estimation  of  residual value is critical to the determination of the
leasing  terms. The Company currently utilizes published valuations for specific
vehicle types in order to determine estimated residual values. However, from the
date  of  origination  of the lease to the date of the termination of the lease,
valuations  for  used  vehicles  change.  The  residual values included in lease
financing  receivables  totaled  $42.8 million and $52.4 million at December 31,
2002  and  2001,  respectively.

     The  Company  has  acquired residual value insurance protection in order to
reduce  the  risk  related to a decline in the published values of used vehicles
between  the date of origination and the date of the lease termination. Residual
value  insurance  is  designed  to  cover  the  difference  between  the
industry-published  valuation for used vehicles at the termination of the lease,
as compared to the industry published valuation at the origination of the lease.

     In  2001,  the  Company's  then  provider  of this residual value insurance
indicated  that they intended to change the source of the industry valuation for
used  vehicles,  which, in essence, reduced the insurance coverage and increased
losses  the  Company  would  realize upon disposition of the leased vehicles. In
January 2000, the Company changed its residual value insurance provider to a new
carrier.  However,  residual  value  insurance coverage related to approximately
$25.0  million  of the lease financing portfolio at December 31, 2001 is insured
by  the  former  insurance  carrier.  At  December  31, 2002, the residual value
insurance  coverage for leases insured by the former insurance carrier decreased
to $8.2 million as a result of maturities and prepayments of leases during 2002.

     Not  withstanding  the  issue associated with the former insurance carrier,
there  is an additional risk in the leasing business with respect to recovery of
residual  values  of leased vehicles. While residual value insurance is designed
to  protect  against a drop in industry published values, and only to the extent
of  any  such  decline, there remains a risk that the actual sales price for the
turned-in leased vehicles is less than the industry-published value. The Company
experienced significant losses in 2001 because the amounts that turned-in leased
vehicles  actually  sold  for  was  less  than  the  published  industry values.

     Throughout  2001,  there  was  significant  weakness in the market for used
vehicles.  This  general weakness was significantly exacerbated by the events of
September  11th  as  well  as  the  extremely  favorable financing opportunities
provided  by large automakers for new vehicles. This situation not only softened
the  demand  for  used  vehicles,  but  increased  the  supply.

     This situation, coupled with the issue associated with the former insurance
carrier discussed above, resulted in an impairment of residual values, which was
other-than-temporary  at December 31, 2001. Accordingly, the Company recorded an
other-than-temporary-impairment  charge  of  $3.5 million in 2001. These charges
were  included  in  other noninterest expenses on the consolidated statements of
income.

     In  2002,  competitive  pressure  from large automakers combined with lower
residual values on automobiles which results in higher lease payments making the
product  less  attractive,  resulted  in  a  15.2% decrease in outstanding lease
financing  at  December 31, 2002 when compared to outstanding lease financing at
December  31,  2001.  During  2002, values for used vehicles stabilized, thereby
lowering the average loss on turned-in leased vehicles during 2002 when compared
to the levels experienced in 2001. The decrease in the average loss on turned-in
leased  vehicles  in  2002  combined  with the decrease in exposure to insurance
coverage  provided  by  the  Company's former insurance carrier discussed above,
resulted  in  no  provision  for the other-than-temporary impairment in residual
values  for  lease  financing  in  2002.

     The estimation of the other-than-temporary-impairment charge was based upon
the current level of leased vehicles turned in as well as the mix of the leasing
portfolio  between  types  of  vehicles.  At  December 31, 2002, the Company has
projected  that  65%  of  its leased vehicles will be turned in. At December 31,
2001,  this  projection  was 71%. At December 31, 2002, approximately 36% of the
Company's leasing portfolio is made up of sport utility vehicles, or SUVs, which
have  experienced the greatest amount of declines in residual values in the used
market,  as  well  as  the  highest  turn-in  rate. Should the amount of vehicle
turn-ins  increase  or  values  for  such  used  vehicles  decline, the level of
other-than-temporary  impairment  might  be  increased.

     The  following  table,  Maturities  and  Sensitivities  of Certain Loans to
Changes in Interest Rates, are the maturities of the commercial and agricultural
and real estate and construction development loan portfolios and the sensitivity
of  loans  to  interest  rate  fluctuations  at  December  31,  2002.  Scheduled
repayments  are  reported  in  the  maturity  category  in which the contractual
payment  is  due.

SECURITIES AND CORRESPONDING INTEREST AND DIVIDEND INCOME

The  average  balance of securities available for sale was $947.0 million, which
is  an  increase  of  $13.9  million,  or 1.5%, from $933.1 million in 2001. The
increase  resulted  primarily from the reinvestment of funds from maturities and
paydowns  from  securities held to maturity and trading securities. The yield on
average  securities  available  for  sale was 5.98% in 2002 compared to 6.63% in
2001.  The  decrease  in  yield,  resulted  in  a decrease in interest income on
securities  available  for  sale  of $5.3 million, from $61.9 million in 2001 to
$56.6  million  in  2002.  The  decrease  in  yield  was caused primarily by the
reinvestment  of funds at lower rates in the declining rate environment in 2002.
The  average  balance  of  securities  held to maturity was $93.0 million during
2002,  which  is  a  decrease  of  $6.9 million, from $99.8 million in 2001. The
decrease  is  primarily  a  result  of  proceeds from maturities and paydowns of
securities  held  to  maturity  reinvested in securities available for sale. The
yield  on  securities  held  to  maturity was 6.04% in 2002 compared to 6.65% in
2001.  Interest  income  on  securities held to maturity decreased $1.0 million,
from  $6.6  million  in  2001  to  $5.6  million  in  2002.

     The  Company  classifies  its  securities  at  date  of  purchase as either
available  for  sale,  held  to  maturity  or  trading.  Held  to  maturity debt
securities  are  those that the Company has the ability and intent to hold until
maturity.  Available  for sale securities are recorded at fair value. Unrealized
holding  gains  and losses, net of the related tax effect, on available for sale
securities  are  excluded from earnings and are reported in stockholders' equity
as  a  component  of  accumulated  other  comprehensive  income or loss. Held to
maturity  securities  are  recorded  at  amortized  cost. Trading securities are
recorded  at  fair  value,  with  net  unrealized  gains  and  losses recognized
currently  in income. Transfers of securities between categories are recorded at
fair value at the date of transfer. A decline in the fair value of any available
for  sale  or  held  to  maturity  security  below  cost  that  is  deemed
other-than-temporary  is charged to earnings resulting in the establishment of a
new  cost  basis  for  the  security.  Securities  with  an other-than-temporary
impairment  are  generally  placed  on  nonaccrual  status.

     Non-marketable equity securities are carried at cost, with the exception of
small  business investment company (SBIC) investments, which are carried at fair
value  in  accordance  with  SBIC  rules.

     Premiums  and  discounts  are  amortized  or  accreted over the life of the
related  security  as an adjustment to yield using the interest method. Dividend

     The  cumulative  writedown  of  the  private  issue collateralized mortgage
obligation  at December 31, 2002 totaled $4.7 million. The asset backed security
was  sold  during  2002 at approximately its carrying value at December 31, 2001
and  the  corporate  debt  security  was  sold  for  $0.1  million  during 2002.

     Included  in  the  securities  available for sale portfolio at December 31,
2002,  are  certain  securities (private issue CMO, asset-backed securities, and
private  issue  mortgaged-backed  securities)  previously  held  by  CNB.

These  securities  contain  a higher level of credit risk when compared to other
securities  held  in  the  Company's  investment  portfolio because they are not
guaranteed  by a governmental agency or a government sponsored enterprise (GSE).
The Company's general practice is to purchase CMO and mortgage-backed securities
that  are  guaranteed  by  a  governmental agency or a GSE coupled with a strong
credit  rating,  typically  AAA,  issued  by  Moody's  or  Standard  and  Poors.

     At December 31, 2002, the amortized cost and fair


22                                               ANNUAL REPORT: NBT BANCORP INC.

value of these high-risk securities amounted to $12.0 million and $10.7 million,
respectively,  down  from  $38.7  million  and  $38.5  million, respectively, at
December  31, 2001. The decrease at December 31, 2002, when compared to December
31,  2001,  resulted  primarily  from  sales  and  to  a lesser extent principal
paydowns. During 2002, the Company sold $22.4 million of these securities due to
a  continued  deterioration  in  the  financial  condition  of  the  underlying
collateral  in  2002 related to a certain number these securities as well as the
Company's  goal  of reducing exposure to these types of securities. The net loss
realized  from  the  sale of these securities was $7.4 million. Offsetting these
net  losses  were  net  gains  of  $7.3  million,  resulting  from  the  sale of
approximately $187.0 million in other securities available for sale during 2002.

     In  January  2002,  the Company had certain embedded derivative instruments
related  to  two  debt securities that have returns linked to the performance of
the  NASDAQ  100  index. Management determined that these debt securities do not
qualify  for  hedge  accounting under SFAS No. 133 (see Impact of New Accounting
Standards).  The  embedded  derivatives  have been separated from the underlying
host  instruments  for  financial  reporting  purposes and accounted for at fair
value.  During  the  year  ended  December  31,  2001, the Company recorded $0.6
million  of  net losses related to the adjustment of the embedded derivatives to
estimated fair value ($0.2 million of which was recorded on January 1, 2001 upon
the  adoption  of  SFAS  No.  133),  which  was  recorded  in net gain (loss) on
securities  transactions  on  the  2001  consolidated  statement  of  income. At
December  31,  2001,  the total amortized cost and estimated fair value of these
two  debt securities was $6.2 million. The two debt securities were sold in 2002
at  amounts  approximating  their  carrying  values  at  December  31,  2001.


FUNDING SOURCES AND CORRESPONDING INTEREST EXPENSE

The  Company  utilizes  traditional deposit products such as time, savings, NOW,
money  market,  and  demand  deposits  as  its primary source for funding. Other
sources,  such  as short-term FHLB advances, federal funds purchased, securities
sold  under agreements to repurchase, brokered time deposits, and long-term FHLB
borrowings  are  utilized as necessary to support the Company's growth in assets
and  to  achieve  interest  rate  sensitivity objectives. The average balance of
interest-bearing  liabilities  remained  relatively  unchanged,  totaling  $2.9
billion  in  2002  and  2001.  The  rate  paid  on  interest-bearing liabilities
decreased  from  4.07%  in  2001  to  2.78%  in  2002.

The decrease in the rate paid on interest bearing liabilities, caused a decrease
in  interest  expense of $37.1 million, or 31.6%, from $117.5 million in 2001 to
$80.4  million  in  2002.


DEPOSITS

Average interest bearing deposits decreased $34.7 million, or 1.4%, during 2002.
The  decrease  resulted  primarily  from  a  decrease in time deposits of $145.2
million,  due  primarily  to the conscious effort to allow runoff of some higher
cost  municipal  time  deposits as well as the sale of a branch in February 2002
which  resulted  in  the  sale  of  $34.3  million  in deposits. Offsetting this
decrease was strong growth in core deposits in 2002. The average balance of NOW,
Money  Market  Deposit Accounts ("MMDA"), and savings comprised 46.2% of average
interest bearing deposits in 2002 compared to 41.1% in 2001. The average balance
of demand deposits increased $37.3 million, or 9.7%, from $382.5 million in 2001
to $419.7 million in 2002. The ratio of average demand deposits to total average
deposits  increased  from  11.3%  in  2001  to  14.5%  in  2002.

     The improvement in the Company's deposit mix noted above, combined with the
falling  interest  rate environment prevalent in 2002, resulted in a decrease in
the  rate  paid  on  interest  bearing deposits of 137 bp, from 3.93% in 2001 to
2.56%  in  2002.  The  average  rate  paid on MMDAs, which are very sensitive to
changes  in interest rates, declined 117 bp from 2.77% in 2001 to 1.60% in 2002.
The  rate  paid on average time deposits decreased 158 bp, from 5.22% in 2001 to
3.64%  in 2002. The decrease in the rate paid on average time deposits, combined
with  the  decline  in the average balance of time deposits, resulted in a $28.6
million  decrease  in interest expense paid on time deposits, from $77.1 million
in  2001  to  $48.5  million  in  2002.

$100,000  or  more  at  December  31,  2002:

BORROWINGS

Average  short-term  borrowings  decreased  from $123.2 million in 2001 to $87.0
million in 2002. Consistent with the decreasing interest rate environment during
2002,  the average rate paid also decreased from 4.36% in 2001 to 1.53% in 2002.
The  decrease  in  the average balance combined with the decrease in the average
rate  paid  caused  interest  expense  on short-term borrowings to decrease $4.0
million  from  $5.4  million  in 2001 to $1.3 million in 2002. Average long-term
debt  increased  $74.9 million, from $259.6 million in 2001 to $334.5 million in
2002.  The  increase in long-term debt and the decrease in short-term borrowings
and  time  deposits was a result of the Company limiting its liability sensitive
position  and  its  exposure  to  rising  interest  rates.

     Short-term  borrowings  consist  of  Federal funds purchased and securities
sold  under repurchase agreements, which generally represent overnight borrowing
transactions,  and other short-term borrowings, primarily Federal Home Loan Bank
(FHLB)  advances,  with original maturities of one year or less. The Company has
unused lines of credit and access to brokered deposits available for short- term
financing  of  approximately  $632 million and $767 million at December 31, 2002
and  2001,  respectively.  Securities  collateralizing repurchase agreements are
held  in  safekeeping by non-affiliated financial institutions and are under the
Company's  control.  Long-term  debt,  which  is  comprised  primarily  of  FHLB
advances,  are collateralized by the FHLB stock owned by the Company, certain of
its mortgage-backed securities and a blanket lien on its residential real estate
mortgage  loans.


RISK  MANAGEMENT

CREDIT  RISK

Credit  risk  is  managed through a network of loan officers, credit committees,
loan  policies,  and  oversight  from  the  senior  credit officers and Board of
Directors.  Management  follows  a policy of continually identifying, analyzing,
and  grading credit risk inherent in each loan portfolio. An ongoing independent
review,  subsequent  to  management's  review,  of  individual  credits  in  the
commercial  loan portfolio is performed by the independent loan review function.
These  components  of  the  Company's  underwriting and monitoring functions are
critical to the timely identification, classification, and resolution of problem
credits.

The  allowance  for  loan and lease losses is maintained at a level estimated by
management  to  provide  adequately  for risk of probable losses inherent in the
current  loan  and  lease  portfolio. The adequacy of the allowance for loan and
lease  losses  is  continuously  monitored.  It is assessed for adequacy using a
methodology  designed  to  ensure the level of the allowance reasonably reflects
the  loan  and lease portfolio's risk profile. It is evaluated to ensure that it
is  sufficient  to absorb all reasonably estimable credit losses inherent in the
current  loan  and  lease  portfolio.

     Management  considers  the  accounting policy relating to the allowance for
loan  and  lease  losses  to  be a critical accounting policy given the inherent
uncertainty  in  evaluating the levels of the allowance required to cover credit
losses in the portfolio and the material effect that such judgements can have on
the  consolidated  results  of  operations.

     For  purposes  of  evaluating  the  adequacy  of the allowance, the Company
considers  a number of significant factors that affect the collectibility of the
portfolio.  For  individually  analyzed  loans,  these include estimates of loss
exposure,  which  reflect the facts and circumstances that affect the likelihood
of  repayment  of such loans as of the evaluation date. For homogeneous pools of
loans  and  leases,  estimates  of  the  Company's  exposure  to  credit  loss


ANNUAL REPORT: NBT BANCORP INC.                                               25

reflect  a  current  assessment  of  a  number  of  factors,  which could affect
collectibility.  These  factors  include:  past  loss  experience;  size, trend,
composition,  and  nature; changes in lending policies and procedures, including
underwriting  standards  and  collection,  charge-offs  and  recoveries;  trends
experienced  in  nonperforming and delinquent loans; current economic conditions
in  the  Company's  market;  portfolio  concentrations  that  may  affect  loss
experienced  across  one  or  more  components  of  the portfolio; the effect of
external factors such as competition, legal and regulatory requirements; and the
experience,  ability,  and  depth  of lending management and staff. In addition,
various  regulatory  agencies,  as  an  integral  component of their examination
process,  periodically review the Company's allowance for loan and lease losses.
Such  agencies  may  require the Company to recognize additions to the allowance
based  on  their  examination.

     After a thorough consideration of the factors discussed above, any required
additions  to  the  allowance for loan and lease losses are made periodically by
charges  to the provision for loan and lease losses. These charges are necessary
to  maintain  the  allowance  at a level which management believes is reasonably
reflective  of  overall  inherent  risk of probable loss in the portfolio. While
management  uses  available information to recognize losses on loans and leases,
additions  to  the allowance may fluctuate from one reporting period to another.
These  fluctuations  are reflective of changes in risk associated with portfolio
content  and/or  changes  in  management's  assessment  of  any  or  all  of the
determining  factors  discussed  above.

     Total  nonperforming  assets  were  $30.5  million  at  December  31, 2002,
compared  to  $49.9  million  at  December 31, 2001. Nonperforming loans totaled
$26.4  million  at  December 31, 2002, down significantly from the $43.8 million
outstanding  at  December  31, 2001. The $17.4 million decrease in nonperforming
loans  from  December  31,  2001  to December 31, 2002, was due to the Company's
successful  efforts  in  resolving certain large problematic commercial loans as
well  as  loan  charge-offs.  Non-accrual  commercial  and  agricultural  loans
decreased  $14.4  million,  from  $31.4  million  at December 31, 2001, to $17.0
million  at  December  31,  2002.  The improvement in the Company's loan quality
ratios  are a direct result of the actions the Company took in 2001 to integrate
credit


26                                               ANNUAL REPORT: NBT BANCORP INC.

administration  functions  of  acquired  banks  into  the Company's conservative
credit culture. Based on the improved trends in loan quality noted above and the
decrease in net charge-offs in 2002 when compared to 2001 highlighted in Table 8
above,  the  Company  recorded  a  provision  for  loan and lease losses of $9.1
million  for  the  year  ended  December  31,  2002, down from the $31.9 million
provided  in  the  same  period  in  2001.

     The  Company's  strategic  focus on loan growth, particularly in commercial
lending, was also a focus of the banks acquired by the Company in 2001 and 2000;
CNB  Bank,  LA  Bank,  NA  and  Pioneer  American Bank, NA (see also Mergers and
Acquisition).  These acquired banks underwrote numerous commercial related loans
prior  to  merging  with  the  Company, based upon their respective underwriting
processes  and  analysis,  including  several  larger  credits  which  became
non-performing  in  2001.  Additionally,  CNB  Bank  significantly increased its
consumer  loan portfolio in recent years. Accordingly, the Company's loan growth
in  general, in particular the growth in higher credit risk loan types, combined
with  the  fact that the recently acquired banks appeared to have used generally
less  conservative  underwriting and monitoring standards increased the inherent
risk  of  loss  in  the  loan  and  lease  portfolio.

     As  the  Company's  loan and lease portfolio continued to grow and the loan
mix  continued  to  move  in the direction of higher credit risk loan types, the
economy  in  the  Company's  market  areas took a dramatic turn for the worse in
2001, especially in the second half of 2001. This sudden economic down turn came
at  a  particularly  bad  time for the Company given the growth in the Company's
higher credit risk loan types. The difficult economic environment experienced in
the  Company's market areas was consistent with what has been experienced by the
national  economy  throughout  2001  and  resulted  in,  among  other  things,
significant  reductions  in  many  borrowers' revenues and cash flows as well as
reduced  valuations  for  certain  real  estate  and  other collateral. In fact,
certain  large  commercial  relationships  in  the  Company's portfolio reported
significant  deterioration  in  the  later  part  of  2001, primarily due to the
difficult  economic  environment.

     During  2001, the Company completed the integration process with respect to
the  Pennstar banking division (formerly LA Bank, N.A. and Pioneer American Bank
N.A.).  The  Company's  integration efforts with the recently merged CNB banking
division  was completed in 2002. The integration process included bringing these
banking  divisions'  credit  administration  practices  in  line with the Bank's
policies, adopting the Bank's credit risk grading system, and upgrading numerous
commercial  real  estate  and other collateral appraisals. At December 31, 2001,
the  credit  administration  function of the Pennstar and CNB banking divisions,
including  workout  and collections, was consolidated and standardized using the
Bank  model,  and  key  personnel  from  the Bank's commercial lending area were
installed  at  Pennstar  and  CNB  to  oversee  the  lending  operations  of the
respective  divisions.

     As  a  result  of the economic downturn, and the integration processes with
respect  to  recently  merged  banks  discussed  above, the Company performed an
extensive  review  of  its  loan  portfolio  during 2001. This review focused on
consistency  in  the  identification and classification of problematic loans and
the measurement of loss exposure on individual loans, especially in light of the
generally  weakened  financial  performance  of borrowers caused by the economic
downturn  and  reduced  collateral  values.

     Non-performing  loans  increased from $26.2 million at December 31, 2000 to
$43.8  million  at  December  31, 2001. The vast majority, approximately 92%, of
nonperforming  loans  are in the non-accrual category. Within non-accrual loans,
all  loan types experienced significant increases, however, the largest increase
was  in  the  commercial  and  agricultural  loans.  Commercial and agricultural
non-accrual  loans,  increased  $17.3 million from $14.1 million at December 31,
2000  to  $31.4  million  at  December 31, 2001. Consumer non-accrual loans also
significantly  increased  from $2.4 million at December 31, 2000 to $3.7 million
at  December  31,  2001.

     As  a result of the reduction in nonperforming loans during 2002, the total
allowance  for  loan  and  lease  losses  is  152.18% of non-performing loans at
December  31,  2002 as compared to 102.19% at December 31, 2001. While loans and
leases  classified  as non-performing have a strong likelihood of experiencing a
loss,  substantially  all  non-performing  loans  are  collateralized, many to a
reasonably  high  percentage  of  the  outstanding  loan  balance.

     Impaired  loans,  which  primarily  consist of non-accruing commercial type
loans  and  all  loans  restructured  in  a  troubled  debt  restructuring, also
decreased significantly, totaling $17.4 million at December 31, 2002 as compared
to  $32.0 million at December 31, 2001. The related allowance for these impaired
loans is $0.5 million or 3.1% of the impaired loans at December 31, 2002 as com-
pared  to $1.4 million and 4.4%, respectively, at December 31, 2001. At December
31,  2002  and 2001 there were $15.5 million and $29.8 million, respectively, of
impaired  loans  which  did  not  have  an  allowance for loan losses due to the
adequacy  of  their  collateral  or  previous  charge  offs.

     Total  net  charge-offs for 2002 totaled $13.7 million as compared to $20.2
million  for  2001.  The  ratio  of  net


ANNUAL REPORT: NBT BANCORP INC.                                              27

charge-offs to average loans was 0.58% for 2002 and 0.87% for 2001. The decrease
in  net  charge-offs  in 2002 resulted from the reduction in nonperforming loans
and  an  improvement  in  loan  quality.  However,  the level of net charge-offs
experienced  in  2002  was  higher  than the Company's net charge-off experience
prior  to  2001.  The higher level of net charge-offs in 2002, resulted from the
increase  in  nonperforming  loans in 2001. Net charge-offs in 2002 exceeded the
2002  provision  for  loan  and  lease  losses  as a result of the Company fully
reserving  certain  of  the  2002  charge-offs, primarily related to nonaccruing
loans  in 2001. As mentioned previously, the provision for loan and lease losses
for  2002  totaled  $9.1  million  down from the $31.9 million provided in 2001.

     For  the  same  reasons  that  non-performing  loans increased in 2001, the
Company  also  experienced  a significant increase in net charge-offs in 2001 as
compared  to  2000.  Net  charge-offs  in  2001 increased $13.8 million to $20.2
million  from  $6.4  in  2000.  Consistent  with  the  above,  the increased net
charge-offs  was  primarily  in the commercial and agricultural portfolio, where
net  charge-offs were $16.0 million in 2001 as compared to $3.4 million in 2000.
Net  charge-offs as a percentage of average loans and leases and leases was .87%
in  2001  as compared to .31% in 2000. As a result of the growth in the loan and
lease  portfolio,  particularly  the  growth in higher credit risk loan types in
2001,  combined with the fact that recently acquired banks appeared to have used
generally  less  conservative  underwriting  and  monitoring  standards,  the
significant  downturn  in  economic  conditions in the Company's market areas as
well  as  the significant increases in non-performing loans and net charge offs,
the  Company  increased its provision for loan and lease losses to $31.9 million
for  2001  from  $10.1  million  in  2000.

     The  allowance  for  loan  and lease losses decreased from $44.7 million at
December  31,  2001,  or  1.91%  of  total loans and leases, to $40.2 million at
December  31,  2002,  or 1.70%. The decrease in the allowance for loan and lease
losses  is  due to net loan charge-offs in 2002 exceeding the 2002 provision for
loan and lease losses, as discussed above. Based upon a thorough analysis of the
inherent  risk  of  loss  in  the  Company's  current  loan and lease portfolio,
management believes that the allowance for loan and lease losses at December 31,
2002  is adequate. However, should the economy worsen, non-performing loans, net
charge  offs  and  provisions  for  loan  and  lease  losses  may  increase.

     The  following  table  sets  forth the allocation of the allowance for loan
losses  by  category,  as  well  as  the  percentage of loans and leases in each
category  to total loans and leases, as prepared by the Company. This allocation
is  based  on management's assessment of the risk characteristics of each of the
component  parts  of the total loan portfolio as of a given point in time and is
subject  to  changes  as  and  when the risk factors of each such component part
change.  The  allocation is not indicative of either the specific amounts of the
loan categories in which future charge-offs may be taken, nor should it be taken
as  an  indicator of future loss trends. The allocation of the allowance to each
category  does  not  restrict  the  use of the allowance to absorb losses in any
category.  The  following  table  sets forth the allocation of the allowance for
loan  losses  by  loan  category.

28                                               ANNUAL REPORT: NBT BANCORP INC.

     In  addition  to  the  nonperforming loans discussed above, the Company has
also  identified  approximately  $48.5  million  in  potential  problem loans at
December  31,  2002 as compared to $48.6 million at December 31, 2001. Potential
problem  loans  are  loans  that  are  currently  performing,  but  where  known
information  about  possible  credit  problems  of  the related borrowers causes
management  to have serious doubts as to the ability of such borrowers to comply
with the present loan repayment terms and which may result in disclosure of such
loans  as  nonperforming  at  some time in the future. At the Company, potential
problem  loans are typically loans that are performing but are classified by the
Company's  loan  rating system as "substandard." At December 31, 2002, potential
problem loans primarily consisted of commercial and agricultural real estate and
commercial and agricultural loans. Management cannot predict the extent to which
economic  conditions  may worsen or other factors which may impact borrowers and
the  potential  problem loans. Accordingly, there can be no assurance that other
loans will not become 90 days or more past due, be placed on non-accrual, become
restructured,  or  require  increased  allowance coverage and provision for loan
losses.

     At  December  31,  2002,  approximately  60.5%  of  the Company's loans are
secured by real estate located in central and northern New York and northeastern
Pennsylvania.  Accordingly, the ultimate collectibility of a substantial portion
of  the  Company's  portfolio  is susceptible to changes in market conditions of
those areas. Management is not aware of any material concentrations of credit to
any  industry  or  individual  borrowers.


LIQUIDITY RISK

Liquidity  involves  the ability to meet the cash flow requirements of customers
who  may  be depositors wanting to withdraw funds or borrowers needing assurance
that  sufficient  funds  will be available to meet their credit needs. The Asset
Liability  Committee  (ALCO)  is  responsible  for  liquidity management and has
developed  guidelines  which  cover  all  assets and liabilities, as well as off
balance  sheet  items that are potential sources or uses of liquidity. Liquidity
policies  must  also provide the flexibility to implement appropriate strategies
and tactical actions. Requirements change as loans and leases grow, deposits and
securities  mature,  and  payments  on borrowings are made. Liquidity management
includes a focus on interest rate sensitivity management with a goal of avoiding
widely  fluctuating  net  interest  margins through periods of changing economic
conditions.

     The  primary liquidity measurement the Company utilizes is called the Basic
Surplus  which  captures  the adequacy of its access to reliable sources of cash
relative  to  the  stability  of  its  funding  mix of average liabilities. This
approach  recognizes  the  importance of balancing levels of cash flow liquidity
from  short  and  long-term  securities  with  the  availability  of  dependable
borrowing  sources  which  can be accessed when necessary. At December 31, 2002,
the  Company's  Basic  Surplus  measurement  was  12.8%  of total assets or $477
million,  which  was above the Company's minimum of 5% or $186 million set forth
in  its  liquidity  policies.

     This  Basic  Surplus  approach  enables  the  Company  to adequately manage
liquidity  from  both operational and contingency perspectives. By tempering the
need  for cash flow liquidity with reliable borrowing facilities, the Company is
able  to  operate  with  a  more  fully invested and, therefore, higher interest
income  generating,  securities  portfolio. The makeup and term structure of the
securities  portfolio  is,  in  part,  impacted  by  the  overall  interest rate
sensitivity  of  the  balance  sheet.  Investment  decisions and deposit pricing
strategies  are  impacted  by  the liquidity position. At December 31, 2002, the
Company  considered  its  Basic  Surplus  adequate  to  meet  liquidity  needs.

     A significant improvement in the economy, may lead to an increase in demand
for  loan  products  as  well  as  an  increase in the demand for equity related
products,  which  in  turn,  could result in a decrease in the Company's deposit
base or result in loan growth exceeding deposit growth. This scenario could lead
to a decrease in its basic surplus measure below the minimum policy level of 5%.
To  manage  this  risk,  the  Company  has the ability to purchase brokered time
deposits, established borrowing facilities with other banks (Federal funds), and
has  the  ability to enter into repurchase agreements with investment companies.
The  additional  liquidity  that could be provided by these measures amounted to
$462  million  at  December  31,  2002.

     At  December 31, 2002, a portion of the Company's loans and securities were
pledged  as collateral on borrowings. Therefore, future growth of earning assets
will  depend  upon  the  Company's ability to obtain additional funding, through
growth  of  core deposits and collateral management, and may require further use
of  brokered  time  deposits,  or  other  higher  cost  borrowing  arrangements.


OFF-BALANCE SHEET RISK

COMMITMENTS TO EXTEND CREDIT

The  Company  makes contractual commitments to extend credit and unused lines of
credit  which  are  subject  to  the


ANNUAL REPORT: NBT BANCORP INC.                                               29

Company's  credit  approval  and monitoring procedures. At December 31, 2002 and
2001,  commitments to extend credit in the form of loans, including unused lines
of  credit,  amounted to $409.1 million and $343.1 million, respectively. In the
opinion  of  management,  there  are  no  material commitments to extend credit,
including  unused lines of credit, that represent unusual risks. All commitments
to  extend  credit in the form of loans, including unused lines of credit expire
within  one  year.


STAND-BY LETTERS OF CREDIT

In  November  2002,  the Financial Accounting Standards Board (FASB) issued FASB
Interpretation  No.  45  (FIN  No.  45),  "Guarantor's Accounting and Disclosure
Requirements  for  Guarantees,  Including Indirect Guarantees of Indebtedness of
Others;  an Interpretation of FASB Statements Nos. 5, 57, and 107 and rescission
of  FASB Interpretation No. 34." FIN No. 45 requires certain new disclosures and
potential  liability-recognition  for  the  fair value at issuance of guarantees
that  fall  within  its  scope. Under FIN No. 45, the Company does not issue any
guarantees  that  would  require liability-recognition or disclosure, other than
its  stand-by  letters  of  credit.

     The  Company  guarantees  the  obligations  or  performance of customers by
issuing  stand-by  letters of credit to third parties. These stand-by letters of
credit  are  frequently issued in support of third party debt, such as corporate
debt  issuances,  industrial  revenue  bonds, and municipal securities. The risk
involved  in  issuing  stand-by letters of credit is essentially the same as the
credit  risk  involved  in  extending loan facilities to customers, and they are
subject  to  the  same  credit origination, portfolio maintenance and management
procedures  in  effect  to  monitor other credit and off-balance sheet products.
Typically, these instruments have terms of five years or less and expire unused;
therefore,  the  total  amounts  do  not  necessarily  represent  future  cash
requirements.  At  December  31,  2002 and 2001, outstanding stand-by letters of
credit  were  approximately  $24.7  million and $21.0 million, respectively. The
fair  value of the Company's stand-by letters of credit at December 31, 2002 was
insignificant.  The  following table sets forth the commitment expiration period
for  stand-by-letters  of  credit  at  December  31,  2002:

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

LOANS SERVICED FOR OTHERS AND LOANS SOLD WITH RECOURSE

The  total  amount  of loans serviced by the Company for unrelated third parties
was approximately $77.2 million and $93.2 million at December 31, 2002 and 2001,
respectively.  At December 31, 2002 and 2001, the Company serviced $15.0 million
and  $18.3  million,  respectively,  of  loans  sold  with  recourse.


RELATED PARTY TRANSACTIONS

In  the  ordinary  course  of business, the Company has made loans at prevailing
rates  and  terms to directors, officers, and other related parties. Such loans,
in  management's  opinion,  do  not  present  more  than  the  normal  risk  of
collectibility  or  incorporate other unfavorable features. The aggregate amount
of loans outstanding to qualifying related parties at December 31, 2002 and 2001
were  $17.0  million  and  $14.6  million,  respectively.

     The  law  firm  of Kowalczyk, Tolles, Deery and Johnston, of which Director
Andrew S. Kowalczyk, Jr., is a partner, provided legal services in the amount of
$116,330  to us and NBT Bank in 2002. The law firms of Harris Beach LLP, Oliver,
Price, & Rhodes, and Needle, Goldenzeil, and Pascale, of which Directors William
L.  Owens,  Paul  D.  Horger, and Gene E. Goldenziel are partners, provide legal
services  to  us  from  time  to time. Arthur J. Gallagher & Co. of New York, of
which  Michael  H. Hutcherson is the Area President, provides insurance services
to  us  from  time  to  time. Payments for services provided by Directors Owens,
Horger,  Goldenziel, and Hutcherson did not exceed $60,000 during 2002. Services
from  these firms were provided in the ordinary course of business and at market
terms.


CAPITAL RESOURCES

Consistent  with  its  goal  to  operate  a  sound  and  profitable  financial
institution,  the  Company  actively  seeks  to  maintain  a  "well-capitalized"
institution  in  accordance  with  regulatory standards. The principal source of
capital to the Company is earnings retention. The Company's capital measurements
are in excess of both regulatory minimum guidelines and meet the requirements to
be  considered  well  capitalized.

     The  Company's  principal  source  of  funds to pay interest on its capital
securities  and  pay  cash  dividends  to its shareholders is dividends from its
subsidiaries.  Various laws and regulations restrict the ability of banks to pay
dividends  to  their  shareholders.  Generally,  the  payment  of


30                                               ANNUAL REPORT: NBT BANCORP INC.

dividends by the Company in the future as well as the payment of interest on the
capital  securities will require the generation of sufficient future earnings by
its  subsidiaries.

     The  Bank  also  is  subject  to substantial regulatory restrictions on its
ability to pay dividends to the Company. Under OCC regulations, the Bank may not
pay a dividend, without prior OCC approval, if the total amount of all dividends
declared  during  the calendar year, including the proposed dividend, exceed the
sum of its retained net income to date during the calendar year and its retained
net  income  over  the  preceding two years. At December 31, 2002, approximately
$9.8  million  of  the  total stockholders' equity of the Bank was available for
payment  of  dividends  to  the  Company without approval by the OCC. The Bank's
ability  to  pay  dividends also is subject to the Bank being in compliance with
regulatory  capital requirements. The Bank is currently in compliance with these
requirements.


STOCK REPURCHASE PLAN

On July 22, 2002, the Company announced that it intended to repurchase up to one
million  shares  (approximately 3%) of its outstanding common stock from time to
time  over  the  next  12  months  in  open  market  and  privately  negotiated
transactions.  Since  the announcement of the Stock Repurchase Plan, the Company
repurchased a total of 475,633 shares in 2002, at an average price of $17.52 per
share. Since the announcement on July 22, 2002, the Company's stock price during
2002  has  ranged  between  $14.76  and  $18.60. The total trading volume of the
Company's  common  stock  for  this  same  period  was approximately 5.4 million
shares,  the  Company's  repurchase  activity  during this period was 10% of the
total trading volume. Total cash allocated for these repurchases during 2002 was
$8.3  million. Under a previous Stock Repurchase Plan announced in October 2001,
the  Company  repurchased  148,700 shares in 2002 at an average price of $16.62.

2002  from  $30.5  million  for 2001. Broker/dealer and insurance fees increased
$1.3  million,  primarily  driven  by  one  of  the Company's financial services
providers,  which  began  operations  in  June 2001, resulting in a full year of
revenue  totaling  $1.6  million  in 2002 compared to seven months of revenue in
2001  totaling  $0.6  million.

     Fees  from service charges on deposit accounts increased $1.1 million or 9%
for  2002 when compared to 2001, primarily from an increase in core deposits and
pricing  adjustments.  Offsetting these increases was a $0.7 million decrease in
trust revenue resulting primarily from declines in assets under management which
resulted  from  stock  market  declines in 2001 and 2002 and the level of estate
activity  in  2002  when  compared  to  2001.

     Net  securities losses totaled $0.4 million in 2002, down from $7.7 million
in 2001. The decrease in net securities losses in 2002 resulted primarily from a
decrease  in  charges  taken  for the other-than-temporary impairment of certain
securities  totaling  $8.3  million in 2001 as compared to $0.7 million in 2002.

increased  $0.7  million  to $49.1 million for 2002 from $48.4 million for 2001.
The increase in salaries and employee benefits was due primarily to increases in
benefits. Incentive compensation increased $1.3 million as a result of increased
profitability  in  2002  when  compared  to  2001, and costs related to employee
medical  insurance  coverage  and  retirement  expense  increased  $0.5 million.
Offsetting  increases  in  benefits  was  a  decrease  in salary expense of $1.1
million,  which  resulted from a reduction in the number of full time equivalent
employees  from  acquisitions  in  2001  and  2000. Occupancy, equipment, office
supplies,  postage, and data processing decreased in 2002 when compared to 2001,
due  mainly  to  efficiencies  realized  from  acquisitions  in  2001  and 2000.
Professional  fees  and  outside  service  costs  in  2002  remained  relatively
consistent  with  2001.

     For  2003, the Company anticipates a decrease in retirement expense related
to  its  defined  benefit  plan  as well as its post retirement health plan. The
anticipated  decrease  in pension expense is expected to amount to approximately
$0.2  million  and  is  a  result  of  a $12 million contribution to the defined
benefit  plan  funded  at  the  end  of  2002  and  the  beginning  of 2003. The
anticipated  decrease in post retirement health expense is expected to amount to
$0.3  million  and  is a result of a plan amendment that increases the amount of
cost  sharing  of health insurance for certain plan participants who had not yet
retired  in  the  plan  that  is  effective  in  2003.

     Amortization  of unidentified intangible assets and goodwill decreased $3.5
million,  to  $0.8  million for 2002 from $4.2 million for 2001. The decrease in
amortization  of  unidentified  intangible assets and goodwill resulted from the
adoption  of  SFAS  No. 142 and SFAS No. 147 in 2002. Capital securities expense
decreased $0.4 million, to $0.8 million for 2002 from $1.3 million for 2001. The
decrease  in  capital securities expense is a result of the Company's guaranteed
preferred  beneficial  interests  in  Company's  junior subordinated debentures,
which  are  tied  to  a variable interest rate index (3-month LIBOR plus 275 bp)
that  was  much  lower  for  2002  when  compared  2001.

     Loan  collection  and  other  real  estate  owned  expenses  increased $0.9
million,  to  $3.0 million for 2002 from $2.1 million for 2001. This increase is
due  primarily  to  the  increase  in  nonperforming  loans  during  2001, which


32                                               ANNUAL REPORT: NBT BANCORP INC.

resulted  in  an  increase  in  collection activity and foreclosure costs during
2002. A charge for the other-than-temporary impairment for lease residual values
totaled  $3.5  million  in  2001  versus no such charge in 2002. Other operating
expense  increased  $1.5  million to $12.7 million in 2002 from $11.2 million in
2001.  The  increase  in  other operating expense was due mainly to increases in
contributions,  insurance  expense,  and  advertising  costs.


INCOME TAXES

In  2002,  income  tax expense was $21.8 million, as compared to $0.5 million in
2001  and  $6.5  million  in  2000.  The Company's effective tax rate was 32.6%,
12.7%,  and  31.6%  in  2002,  2001, and 2000, respectively. The decrease in the
effective  tax  rate  during  2001  is  primarily the result of lower net income
before  tax,  which  resulted  in a greater benefit, on a percentage basis, from
permanent  non-taxable  items  such  as  tax-exempt  interest.


2001 OPERATING RESULTS AS COMPARED TO 2000 OPERATING RESULTS

NET INTEREST INCOME

On a tax equivalent basis, the Company's net interest income for 2001 was $141.8
million,  up  from  $131.5  million  for 2000. The Company's net interest margin
improved  to 4.19% for 2001 from 4.02% for 2000. The improvement in net interest
income and net interest margin in 2001 were due primarily to two factors. First,
earning  assets increased from $3.3 billion in 2000 to $3.4 billion in 2001. The
increase  in  average earning assets was due primarily to an increase in average
loans  and  leases,  which increased $221.5 million from $2.1 billion in 2000 to
$2.3  billion in 2001. Secondly, due to the falling interest rate environment in
2001 and the Company's interest bearing liability sensitive position, rates paid
on  interest bearing liabilities declined more rapidly than the yield on earning
assets.  Rates  paid  on  interest bearing liabilities decreased 68 basis points
("bp") to 4.07% in 2001 from 4.75% in 2000 compared to a 42 bp decrease in yield
on  earnings  assets  to  7.66%  in  2001  from  8.08%  in  2000.


LOANS AND LEASES AND CORRESPONDING INTEREST AND FEES ON LOANS

The  average  balance  of  loans and leases increased 9.5%, from $2.1 billion in
2000  to  $2.3  billion in 2001. The yield on average loans and leases decreased
from  8.71%  in  2000  to  8.13% in 2001, as a falling interest rate environment
prevailed  for  much  of  2001.  Interest income from loans and leases increased
3.2%,  from  $182.3  million  in 2000 to $188.1 million in 2001. The increase in
interest  income  from  loans  and leases was due to the increase in the average
balance  of loans and leases of 9.5%, offset by a decrease in yield on loans and
leases  in  2001  of  58  bp  when  compared  to  2000.

     Total loans and leases were $2.3 billion at December 31, 2001, up from $2.2
billion  at December 31, 2000. The increase in loans and leases was primarily in
consumer  and  commercial loan types, as management continued to focus on growth
in  these  areas.  Consumer  loans  increased  in  2001,  from $357.8 million at
December  31,  2000 to $387.1 million at December 31, 2001, an increase of $29.3
million  or  8.2%.  Residential real estate mortgages increased $20.8 million or
4.1%  to  $525.4 million at December 31, 2001. Home equity loans increased $13.3
million  or 6.0% to $232.6 million at December 31, 2001. During 2001, commercial
and agricultural loans and real estate increased $9.6 million and $11.2 million,
respectively.


SECURITIES AND CORRESPONDING INTEREST AND DIVIDEND INCOME

The  average  balance of securities available for sale was $933.1 million, which
is a decrease of $84.6 million, or 8.3%, from $1.0 billion in 2000. The decrease
is  primarily  a  result  of  proceeds  from  sales,  maturities and paydowns of
securities  available  for  sale  used to fund loan growth. The yield on average
securities  available  for sale was 6.63% in 2001 compared to 6.97% in 2000. The
decrease  in  the average balance of securities available for sale, coupled with
the  decrease  in yield, resulted in a decrease in interest income on securities
available  for sale of $9.0 million, from $70.9 million in 2000 to $61.9 million
in  2001.  The  average balance of securities held to maturity was $99.8 million
during  2001, which is a decrease of $17.7 million, from $117.5 million in 2000.
As  noted  above, the decrease is primarily a result of proceeds from maturities
and pay-downs of securities held to maturity used to fund loan growth. The yield
on  securities  held  to  maturity  was 6.65% in 2001 compared to 6.88% in 2000.
Interest income on securities held to maturity decreased $1.5 million, from $8.1
million  in  2000  to  $6.6  million  during  2001.


ANNUAL REPORT: NBT BANCORP INC.                                               33

FUNDING SOURCES AND CORRESPONDING INTEREST EXPENSE DEPOSITS

Average  interest  bearing  deposits  increased  $146.5 million, or 6.2%, during
2001,  to $2.5 billion. The increase is due primarily to the full year effect in
2001 on average interest bearing deposits related to branch acquisitions in June
and  November  of  2000 as well as the FNB acquisition in June 2001. The Company
assumed  $133.7  million in deposit liabilities in conjunction with those branch
acquisitions.  Additionally,  the  Company  completed  the  acquisition of First
National  Bancorp, Inc. in June of 2001 and assumed approximately $94 million in
interest  bearing  liabilities. The Company's core deposit mix improved in 2001.
The  average  balance  of  NOW,  MMDA,  and  savings  comprised 41.1% of average
interest bearing deposits in 2001 compared to 39.9% in 2000. The average balance
of demand deposits increased $34.1 million, or 9.8%, from $348.4 million in 2000
to $382.5 million in 2001. The ratio of average demand deposits to total average
deposits  increased  from  10.6%  in  2000  to  11.3%  in  2001.

     The improvement in the Company's deposit mix noted above, combined with the
falling  interest  rate environment prevalent in 2001, resulted in a decrease in
the  rate  paid  on interest bearing liabilities of 61 bp, from 4.54% in 2000 to
3.93%  in  2001.  The  average  rate  paid on MMDAs, which are very sensitive to
changes  in interest rates, declined 127 bp from 4.04% in 2000 to 2.77% in 2001.
The  rate  paid  on average time deposits decreased 50 bp, from 5.72% in 2000 to
5.22%  in 2001. The decrease in the rate paid on average time deposits, combined
with the reduction in average time deposits, resulted in a $5.3 million decrease
in  interest  expense paid on time deposits, from $82.4 million in 2000 to $77.1
million  in  2001.


BORROWINGS

Average  short-term  borrowings  decreased from $194.9 million in 2000 to $123.2
million in 2001. Consistent with the decreasing interest rate environment during
2001,  the average rate paid also decreased from 6.13% in 2000 to 4.36% in 2001.
The  decrease  in  the average balance combined with the decrease in the average
rate  paid  caused  interest  expense  on short-term borrowings to decrease $6.5
million,  from  $11.9 million in 2000 to $5.4 million in 2001. Average long-term
debt  increased  $14.2 million, from $245.4 million in 2000 to $259.6 million in
2001.  The  increase  in  long-term  debt combined with a decrease in short-term
borrowings  was  a result of limiting the Company's liability sensitive position
to  rising  interest  rates.


NONINTEREST  INCOME

Total noninterest income excluding net securities losses and a gain on sale of a
building  increased  to $30.5 million in 2001, compared to $24.9 million in 2000
and  $21.3  million  in 1999. Broker/dealer fees and insurance revenue increased
$1.8  million  in  2001  over  2000. The increase reflects twelve full months of
revenue  from the Company's broker/dealer, M. Griffith, Inc., which was acquired
in  May  2000.  Revenues  from  M.  Griffith, Inc. totaled $3.8 million in 2001,
compared  to  $2.7 million in 2000. Additionally, the Company's insurance agency
and  financial  services  provider,  CFS,  which started operating in June 2001,
contributed  to the increase in revenue as well. Revenues for CFS, Inc. for 2001
totaled  $0.6  million.

     Income  from trust services decreased $0.1 million in 2001 when compared to
2000.  The  decrease is primarily attributable to a decrease in the market value
of  the  assets held by the Company in a fiduciary capacity. The decrease in the
market value of assets held by the Company in a fiduciary capacity resulted from
the  decline  in all the major stock indexes during 2001. Other income increased
$1.4  million  in  2001  when  compared  to  2000.  The increase in other income
resulted  primarily from increases in ATM fees and other banking fees. Total ATM
fees  and  other  banking  fees  amounted  to  $4.4  million  and  $1.6 million,
respectively,  for 2001 compared to $3.8 million and $0.6 million, respectively,
for  2000. The increase in ATM fees resulted from the combination of an increase
in  ATMs deployed and increases in ATM convenience fees. The increase in banking
fees resulted primarily from the continued focus in business banking activities.

     Net securities losses totaled $7.7 million in 2001 compared to $2.3 million
in  2000.  The increase in net securities losses in 2001 resulted primarily from
charges  totaling  $8.3 million taken for the other-than-temporary impairment of
certain  securities  compared to $3.5 million in 2000. The Company sold a branch
building  in  2001which  resulted  in  a  gain  of  $1.4  million.


NONINTEREST EXPENSE

For  2001,  noninterest  expense  excluding  merger  charges and certain deposit
overdraft  writeoffs  increased  $12.9  million,  or  13.5%,  to  $108.4 million
compared  to  $95.5  million  in 2000. This increase was due to several factors.
Expenses  for  data  processing  and  communications  and  professional fees and
outside  services  increased  period-over-period  by  $3.7  million  or  28.1%,
principally  due to the Company's expanded branch network, costs associated with
enhanced  technologies  and  expanded  data


34                                               ANNUAL REPORT: NBT BANCORP INC.

processing  volume capacities resulting from recent data processing conversions.

     Salaries  and employee benefits expense increased $3.6 million, or 8.1%, to
$48.4  million  compared  to  $44.8 million in 2000. Occupancy expense increased
$943,000,  or  12.2%,  to  $8.7  million  compared  to $7.8 million in 2000. The
increases  in  salaries  and  employee  benefits  expense  and occupancy expense
resulted  primarily  from  twelve  full  months  of  expenses in 2001 from eight
branches  and  the Company's broker/dealer, M. Griffith, Inc., all of which were
acquired  during 2000, and an increase in expense resulting from the acquisition
of  FNB  Bancorp,  Inc.  on  June  1,  2001.

     Office  supplies  and  postage  increased from $4.0 million in 2000 to $4.6
million  in  2001.  The  increase  resulted  primarily  from  the  growth of the
Company's  branch  network  during  2000  and  2001. Capitals securities expense
decreased  from  $1.6  million  in  2000  to  $1.3 million in 2001. The decrease
resulted  from  a  decrease  during  2001  in  the  index the capital securities
interest  rate  is  tied  to.

     Residual  value  lease  losses  increased from $0.6 million in 2000 to $3.5
million  in  2001.  The  increase  was  due  to  the  charge  taken  for  the
other-than-temporary  impairment  of  residual  values  of leased automobiles in
2001.  There  was  an  increase  in  expenses  relating  to  the amortization of
intangible  assets  from  certain  recently completed acquisitions. Amortization
expenses  increased  $1.2  million  for  2001  as  compared  to  2000.

     Merger,  acquisition  and reorganization costs amounted to $15.3 million in
2001 compared to $23.6 million in 2000. The Company completed one merger and one
acquisition  in 2001 and completed two mergers, one acquisition, and purchased 8
branches  in  2000.  Additionally,  in  2000, the Company cancelled one proposed
merger.  During  2001,  the Company recognized $2.1 million in deposit overdraft
write-offs  related  to  two  large  check-kiting  incidents.

IMPACT OF INFLATION AND CHANGING PRICES

The  Company's consolidated financial statements are prepared in accordance with
generally  accepted  accounting  principles  which  require  the  measurement of
financial  position and operating results in terms of historical dollars without
considering  the changes in the relative purchasing power of money over time due
to inflation. The impact of inflation is reflected in the increasing cost of the
Company's  operations.  Unlike  most industrial companies, nearly all assets and
liabilities  of  the  Company  are  monetary. As a result, interest rates have a
greater  impact  on  the  Company's  performance  than do the effects of general
levels  of inflation. In addition, interest rates do not necessarily move in the
direction  of,  or  to  the  same  extent  as  the  price of goods and services.

IMPACT OF NEW ACCOUNTING STANDARDS

NEW  ACCOUNTING  PRONOUNCEMENT-ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING
ACTIVITIES

The  Company  adopted the provisions of SFAS No. 133, "Accounting for Derivative
Instruments  and  Hedging  Activities," effective January 1, 2001. At that time,
the  Company  had  certain  embedded  derivative  instruments  from the recently
acquired  CNB Bank related to a deposit product and two debt securities that had
costs  and returns linked to the performance of the NASDAQ 100 Index. Management
determined  that  these  debt securities and the deposit product did not qualify
for hedge accounting under SFAS No. 133. The embedded derivatives were separated
from  the  underlying  host  instruments  for  financial  reporting purposes and
accounted  for at fair value. In connection with the adoption of SFAS No. 133 as
of  January  1, 2001, the Company recorded a charge to earnings for a transition
adjustment  of  $159,000  ($95,000,  after-tax)  for the net impact of recording
these  embedded derivatives on the consolidated balance sheet at fair value. Due
to the insignificance of the amount, the transition adjustment was not reflected
as  a  cumulative  effect  of  a  change  in  accounting  principle  on the 2001
consolidated  statement  of  income , but was instead recorded in net securities
(losses)  gains. During the year ended December 31, 2001, and before the closing
of  the  CNB  merger,  the  Company  recorded a $640,000 net loss related to the
adjustment  of  the embedded derivatives to fair value. As of December 31, 2001,
the  embedded derivatives referred to above were completely written off as these
derivatives  had  no  value.  During  the  first  quarter  of 2002, the two debt
securities  with  embedded  derivative  instruments  noted  above  were  sold at
approximately  their  carrying  value,  as  the securities did not meet the risk
profile  of  the  Company's  security  portfolio.

     At  December  31,  2002,  the Company has no other derivatives as currently
defined  by  SFAS  No.  133.

NEW ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS

On  August  16,  2001,  the  FASB  issued  SFAS  No.  143  "Accounting for Asset
Retirement  Obligations."  Statement  143  addresses  financial  accounting  and
reporting  for  obligations  associated  with  retirement of tangible long-lived
assets  and  the associated asset retirement costs. Statement 143 applies to all
entities.  This  Statement


ANNUAL REPORT: NBT BANCORP INC.                                               35

requires  that  the fair value of a liability for an asset retirement obligation
be  recognized in the period in which it is incurred if a reasonable estimate of
fair value can be made. The associated asset retirement costs are capitalized as
part  of  the carrying amount of the long-lived asset. Under this Statement, the
liability  is  discounted  and  the  accretion  expense  is recognized using the
credit-adjusted risk-free  interest  rate  in  effect  when  the  liability  was
initially  recognized. The FASB issued this Statement to provide consistency for
the  accounting  and  reporting of liabilities associated with the retirement of
tangible  long-lived  assets  and  the  associated  asset  retirement costs. The
Statement  is  effective  for  financial  statements  issued  for  fiscal  years
beginning  after  June  15,  2002. Earlier application is permitted. The Company
does  not expect a material impact on its consolidated financial statements when
this  Statement  is  adopted.


NEW  ACCOUNTING  PRONOUNCEMENT-ACCOUNTING  FOR  THE  IMPAIRMENT  OR  DISPOSAL OF
LONG-LIVED  ASSETS

On  October 3, 2001, The FASB issued SFAS No. 144 "Accounting for the Impairment
or Disposal of Long-Lived Assets." This Statement addresses financial accounting
and  reporting  for  the  impairment  or  disposal  of  long-lived  assets. This
Statement  supersedes  SFAS No. 121 "Accounting for the Impairment of Long-Lived
Assets  and  for  Long-Lived  Assets  to  be  Disposed  Of." This Statement also
supersedes  the  accounting  and  reporting  provisions  of  APB  Opinion No. 30
"Reporting  the  Results  of  Operations-Reporting  the Effects of Disposal of a
Segment  of  a  Business,  and Extraordinary, Unusual and Infrequently Occurring
Events  and  Transactions."  The  changes  in  this  Statement improve financial
reporting  by  requiring that one accounting model be used for long-lived assets
to  be  disposed of by broadening the presentation of discontinued operations to
include  more disposal transactions. The Company's core deposit intangible asset
will  be measured for impairment under SFAS No. 144. This Statement is effective
for  financial  statements  issued for fiscal years beginning after December 15,
2001.  The  Company  adopted the provisions of SFAS No. 144 effective January 1,
2002,  and  the  adoption  did  not  have  a material impact on its consolidated
financial  statements.


NEW ACCOUNTING PRONOUNCEMENT-RESCISSION OF FASB STATEMENTS NO. 4, 44 AND 64

In  April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No.
4,  44,  and 64, Amendment of FASB Statement No. 13, and Technical Corrections."
SFAS  No.  145  rescinds  SFAS  No.  4,  "Reporting  Gains  and  Losses  from
Extinguishment  of Debt," which required gains and losses from extinguishment of
debt to be aggregated and, if material, classified as an extraordinary item, net
of  related  income tax effect. Upon adoption of SFAS No. 145, companies will be
required  to  apply the criteria in Accounting Principles Board, or APB, Opinion
No.  30,  "Reporting the Results of Operations-Reporting the Effects of Disposal
of  a  Segment  of  a  Business,  and  Extraordinary,  Unusual  and Infrequently
Occurring  Events  and  Transactions" in determining the classification of gains
and  losses  resulting from the extinguishment of debt. Upon adoption, companies
must  reclassify  prior  period  items  that  do not meet the extraordinary item
classification criteria in APB Opinion No. 30. Additionally, SFAS No. 145 amends
SFAS  No.  13,  "Accounting  for  Leases,"  to  require  that  certain  lease
modifications  that have economic effects similar to sale-leaseback transactions
be  accounted  for  in  the  same  manner  as  sale-leaseback  transactions. The
provisions of SFAS No. 145 related to the rescission of SFAS No. 4 are effective
for  fiscal years beginning after May 15, 2002. All other provisions of SFAS No.
145  are effective for transactions occurring and/or financial statements issued
on  or  after May 15, 2002. The implementation of SFAS No. 145 provisions, which
were  effective May 15, 2002, did not have a material impact on our consolidated
financial  condition  or  results  of  operations.  The  implementation  of  the
remaining  provisions  is  not  expected  to  have  a  material  impact  on  our
consolidated  financial  condition  or  results  of  operations.


NEW  ACCOUNTING  PRONOUNCEMENT-ACCOUNTING  FOR  COSTS  ASSOCIATED  WITH  EXIT OR
DISPOSAL  ACTIVITIES

In  June  2002,  the  FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities." This Statement addresses financial accounting
and  reporting  for  costs  associated  with  exit  or  disposal  activities and
nullifies  Emerging  Issues  Task  Force  (EITF)  Issue  No.  94-3,  "Liability
Recognition for Certain Employee Termination Benefits and Other Costs to Exit an
Activity  (including Certain Costs Incurred in a Restructuring)." This Statement
is  effective for exit or disposal activities initiated after December 31, 2002.
The  Company  will  review  the  impact of applying this standard to any exit or
disposal  activities  initiated  after  December  31,  2002.


NEW  ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR BUSINESS COMBINATIONS, GOODWILL AND
OTHER  INTANGIBLES, AND CERTAIN ACQUISITION OF BANKING OR THRIFT INSTITUTIONS

In  July  2001,  the FASB issued SFAS No. 141, "Business Combinations," and SFAS
No.  142,  "Goodwill  and  Other


36                                               ANNUAL REPORT: NBT BANCORP INC.

Intangible Assets." SFAS No. 141 requires that the purchase method of accounting
be  used for all business combinations initiated after June 30, 2001, as well as
all  purchase  method  business combinations completed after June 30, 2001. SFAS
No.  141  also  specifies criteria that intangible assets acquired in a purchase
method  business  combination must meet to be recognized and reported apart from
goodwill.  SFAS  No.  142  requires  that  goodwill  and  intangible assets with
indefinite  useful  lives  no  longer  be  amortized,  but  instead  tested  for
impairment  at least annually in accordance with the provisions of SFAS No. 142.
SFAS  No. 142 also requires that intangible assets with definite useful lives be
amortized  over  their  respective  estimated  useful  lives  to their estimated
residual  values,  and  reviewed for impairment in accordance with SFAS No. 144.

     The  Company adopted the provisions of SFAS No. 141 effective July 1, 2001,
and  adopted  the provisions of SFAS No. 142 effective January 1, 2002. SFAS No.
141  requires  that upon adoption of SFAS No. 142, that the Company evaluate its
existing  intangible  assets and goodwill that were acquired in a prior purchase
business  combination,  and  to make any necessary reclassifications in order to
conform  with  the  new  criteria  in  SFAS  No.  141 for recognition apart from
goodwill.  Upon  adoption  of SFAS No. 142, the Company was required to reassess
the  useful  lives  and  residual  values  of  all intangible assets acquired in
purchase  business  combinations,  and  make  any  necessary amortization period
adjustments  by the end of the first interim period after adoption. In addition,
to  the extent an intangible asset was identified as having an indefinite useful
life,  the  Company  is  required to test the intangible asset for impairment in
accordance with the provisions of Statement 142 within the first interim period.
Goodwill  is  required  to  be  tested  for impairment, by the end of 2002, with
impairment adjustments, if any, recorded as of the beginning of 2002.

     During  the first quarter of 2002, upon the implementation of SFAS No. 142,
the  Company  performed  a  reevaluation  of  the  remaining useful lives of all
previously  recognized  intangible assets and found no adjustment necessary. The
Company  has  completed  its transitional goodwill impairment evaluation and has
concluded  there  is no impairment losses from the adoption of SFAS No. 142. The
Company  has  not identified any intangible assets with indefinite useful lives.

     The unidentified intangible assets acquired in the acquisition of a bank or
thrift  (including  acquisitions  of branches meeting certain conditions), where
the  fair  value of the liabilities assumed exceeds the fair value of the assets
acquired,  was  amortized  to expense under SFAS No. 72, "Accounting for Certain
Acquisitions  of Banking or Thrift Institutions." In October 2002, SFAS No. 147,
"Acquisitions  of  Certain  Financial  Institutions," was issued. This Statement
amends SFAS No. 72 and 144 and FIN No. 9. Except for transactions between two or
more  mutual  enterprises,  this  Statement  removes  acquisitions  of financial
institutions  from the scope of both SFAS No. 72 and FIN No. 9 and requires that
those  transactions  be accounted for in accordance with SFAS No. 141, "Business
Combinations," and No. 142, "Goodwill and Other Intangible Assets." Accordingly,
unidentified  intangibles  related  to certain branch acquisitions are no longer
amortized,  but  are  subject  to  impairment  testing  under  SFAS  No. 142. In
addition,  this Statement amends SFAS No. 144, "Accounting for the Impairment or
Disposal  of  Long-Lived  Assets,"  to  include  in  its  scope  long-term
customer-relationship  intangible  assets  of  financial  institutions  such  as
depositor-and  borrower-relationship  intangible  assets  and  credit cardholder
intangible assets. Consequently, those intangible assets are subject to the same
undiscounted  cash  flow recoverability test and impairment loss recognition and
measurement  provisions  that  SFAS No. 144 requires for other long-lived assets
that  are  held  and  used.  SFAS No. 147 is effective October 1, 2002, with the
application  of  its  provisions  applied  retroactively  to  January  1,  2002.

     Upon  the  adoption  of  SFAS No.142 on January 1, 2002, the Company ceased
amortizing  its  goodwill. Upon the adoption of SFAS No. 147 on October 1, 2002,
approximately  $30.6 million of unidentified intangible assets were reclassified
to  goodwill  retroactive  to  January 1, 2002. The adoption of SFAS No. 142 and
SFAS  No.  147 decreased noninterest expense and increased net income in 2002 as
compared  to  2001  and 2000. The following table shows the pro forma effects of
applying  SFAS  No.  142  and  SFAS  No. 147 to the 2001 and 2000 periods, and a
summary  of  goodwill  by  operating  subsidiaries  follows:

     The  Company  has finite-lived intangible assets capitalized on its balance
sheet  in the form of core deposit and other intangible assets. These intangible
assets  continue to be amortized over their estimated useful lives in accordance
with  SFAS  No.  142,  which  range from one to twenty-five years. There were no
adjustments  to  the  useful lives of these intangible assets as a result of the

NEW ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR STOCK BASED COMPENSATION

In  December  2002,  the  FASB  issued SFAS No. 148, "Accounting for Stock-Based
Compensation-Transition  and  Disclosure,"  which  provides  guidance  on how to
transition  from  the  intrinsic  value  method  of  accounting  for stock-based
employee  compensation  under  APB No. 25 to SFAS No. 123's fair value method of
accounting, if a company so elects. The Company currently intends to continue to
account  for  stock-based  employee  compensation  under  APB  No.  25  in 2003.


NEW ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR GUARANTEES

In  November  2002,  the  FASB  issued (FIN No. 45), "Guarantor's Accounting and
Disclosure  Requirements  for  Guarantees,  Including  Indirect  Guarantees  of
Indebtedness  of Others." This interpretation expands the disclosures to be made
by  a  guarantor in its financial statements about its obligations under certain
guarantees  and  requires  the  guarantor  to recognize a liability for the fair
value  of  an  obligation  assumed  under  a guarantee. FIN No. 45 clarifies the
requirements  of  SFAS  No.  5,  "Accounting  for  Contingencies,"  relating  to
guarantees.  In  general,  FIN  No.  45  applies to contracts or indemnification
agreements  that  contingently  require  the  guarantor  to make payments to the
guaranteed  party based on changes in an underlying that is related to an asset,
liability,  or  equity  security  of  the  guaranteed  party.  Certain guarantee
contracts  are excluded from both the disclosure and recognition requirements of
this  interpretation,  including,  among others, guarantees relating to employee
compensation,  residual  value  guarantees  under  capital  lease  arrangements,
commercial  letters  of  credit,  loan  commitments, subordinated interests in a
special  purpose  entity,  and guarantees of a company's own future performance.
Other  guarantees  are  subject to the disclosure requirements of FIN No. 45 but
not  to  the  recognition  provisions  and  include,  among  others, a guarantee
accounted  for  as  a  derivative  instrument  under  SFAS  No.  133, a parent's
guarantee  of  debt owed to a third party by its subsidiary or vice versa, and a
guarantee  which  is based on performance not price. The disclosure requirements
of FIN No. 45 are effective for the Company as of December 31, 2002, and require
disclosure  of  the  nature  of  the  guarantee, the maximum potential amount of
future  payments  that  the  guarantor  could  be  required  to  make  under the
guarantee,  and the current amount of the liability, if any, for the guarantor's
obligations  under  the guarantee. The recognition requirements of FIN 45 are to
be  applied  prospectively  to  guarantees issued or modified after December 31,
2002.  The  Company  does  not  expect  the requirements of FIN No. 45 to have a
material  impact  on results of the Company's consolidated operations, financial
position,  or  liquidity.


NEW ACCOUNTING PRONOUNCEMENT-CONSOLIDATION OF VARIABLE INTEREST ENTITIES

In January 2003, the FASB issued FIN No. 46, "Consolidation of Variable Interest
Entities." The objective of this interpretation is to provide guidance on how to
identify  a  variable  interest  entity  (VIE)  and  determine  when the assets,
liabilities,  noncontrolling  interests, and results of operations of a VIE need
to  be included in a company's consolidated financial statements. A company that
holds variable interests in an entity will need to consolidate the entity if the
company's interest in the VIE is such that the company will absorb a majority of
the  VIE's  expected  losses  and/or receive a majority of the entity's expected
residual returns, if they occur. FIN No. 46 also requires additional disclosures
by  primary  beneficiaries  and other significant variable interest holders. The
provisions  of  this  interpretation  became  effective  upon  issuance.  The
requirements  of  FIN  No.  46  will not have a material impact on the Company's
consolidated  results  of  operations,  financial  position,  or  liquidity.

Item 7A.  Quantitative and Qualitative Disclosure About Market Risk
- --------------------------------------------------------------------------------

MARKET  RISK

Interest  rate  risk  is the most significant market risk affecting the Company.
Other  types  of  market  risk,  such as foreign currency exchange rate risk and
commodity  price  risk,  do  not  arise  in  the  normal course of the Company's
business  activities.

     Interest  rate  risk  is  defined  as an exposure to a movement in interest
rates  that  could  have an adverse effect on the Company's net interest income.
Net  interest  income  is  susceptible  to interest rate risk to the degree that
interestbearing  liabilities mature or reprice on a different basis than earning
assets.  When  interest-bearing  liabilities mature or reprice more quickly than
earning  assets  in  a  given  period, a significant increase in market rates of
interest  could  adversely  affect  net interest income. Similarly, when earning
assets mature or reprice more quickly than interest-bearing liabilities, falling
interest  rates  could  result  in  a  decrease  in  net  interest  income.

     In  an  attempt  to  manage  the  Company's exposure to changes in interest
rates,  management  monitors  the  Company's  interest  rate  risk. Management's
asset/liability  committee (ALCO) meets monthly to review the Company's interest
rate  risk  position  and  profitability,  and  to  recommend  strategies  for
consideration  by  the  Board  of  Directors.  Management  also reviews loan and
deposit  pricing,  and the Company's securities portfolio, formulates investment
and  funding  strategies,  and  oversees  the  timing  and  implementation  of
transactions  to  assure  attainment  of  the  Board's  objectives  in  the most
effective  manner.  Notwithstanding  the Company's interest rate risk management
activities, the potential for changing interest rates is an uncertainty that can
have  an  adverse  effect  on  net  income.

     In  adjusting  the  Company's  asset/liability  position,  the  Board  and
management  attempt  to  manage the Company's interest rate risk while enhancing
the  net  interest  margin. At times, depending on the level of general interest
rates,  the  relationship  between  long  and  short-term interest rates, market
conditions  and  competitive  factors, the Board and management may determine to
increase the Company's interest rate risk position somewhat in order to increase
its  net  interest margin. The Company's results of operations and net portfolio
values  remain  vulnerable  to changes in interest rates and fluctuations in the
difference  between  long  and  short-term  interest  rates.

     The primary tool utilized by ALCO to manage interest rate risk is a balance
sheet/income  statement  simulation  model (interest rate sensitivity analysis).
Information such as principal balance, interest rate, maturity date, cash flows,
next  re-pricing  date (if needed), and current rates is uploaded into the model
to  create  an ending balance sheet. In addition, ALCO makes certain assumptions
regarding prepayment speeds for loans and leases and mortgage related investment
securities  along  with  any  optionality  within  the  deposits and borrowings.

     The model is first run under an assumption of a flat rate scenario (i.e. no
change  in  current  interest rates) with a static balance sheet over a 12-month
period. Three additional models are run in which a gradual increase of 200 bp, a
gradual  increase  of  200 bp where the long end of the yield curve remains flat
(the long end of the yield curve is defined as 5 years and longer) and a gradual
decrease  of  100  bp  takes  place over a 12 month period with a static balance
sheet.  Under  these  scenarios,  assets  subject to prepayments are adjusted to
account  for  faster or slower prepayment assumptions. Any investment securities
or  borrowings  that  have  callable  options  embedded  into  them  are handled
accordingly  based  on  the interest rate scenario. The resultant changes in net
interest  income  are  then  measured  against  the  flat  rate  scenario.

     In  the  declining  rate  scenarios,  net  interest  income is projected to
decrease  slightly  when  compared  to the forecasted net interest income in the
flat  rate  scenario through the simulation period. The decrease in net interest
income  is  a  result  of  interest-bearing  liabilities repricing downward at a
slower  rate  than  earning  assets.  The inability to effectively lower deposit
rates  will  likely  reduce or eliminate the benefit of lower interest rates. In
the rising rate scenarios, net interest income is also projected to experience a
decline  from the flat rate scenario. Net interest income is projected to remain
at  lower  levels  than  in  a  flat rate scenario through the simulation period
primarily  due  to  a  lag in assets repricing while funding costs increase. The
potential  impact  on  earnings  is  dependent  on  the  ability  to lag deposit
repricing.

     Net  interest  income for the next twelve months in the +200/+ 200 flat/100
bp  scenarios,  as described above, is within the internal policy risk limits of
not  more  than  a  7.5%  change  in  net  interest  income. The following table
summarizes  the  percentage  change  in  net  interest  income in the rising and
declining rate scenarios over a 12-month period from the forecasted net interest
income  in  the  flat  rate  scenario  using the December 31, 2002 balance sheet
position:

- - 100                                     (0.53%)
==================================================


     Under  the  flat  rate  scenario  with a static balance sheet, net interest
income  is  anticipated  to  decrease approximately 3.0% from total net interest
income  for  2002.  The  Company  anticipates  under current conditions, earning
assets  will  continue  to  reprice  at  a  faster  rate  than  interest bearing
liabilities.  In  order  to  protect  net  interest  income from anticipated net
interest  margin  compression,  the Company will continue to focus on increasing
low  cost core funding as well as growing earning assets through loan growth and
leverage  opportunities.  However,  if the Company cannot increase low cost core
funding  and  earning assets, the Company expects net interest income to decline
in  2003.

     Currently,  the  Company  is  holding  fixed  rate  residential real estate
mortgages  in its loan portfolio. One of the major factors the Company considers
in  holding  residential  real  estate  mortgages is its level of core deposits.
Current  core  deposit  levels  have  enabled  the  Company  to  hold fixed rate
residential  real  estate mortgages without having a negative impact on interest
rate  risk,  as  the Company is well matched at December 31, 2002. The Company's
net  interest  income  is  projected to decrease by only 0.08% if interest rates
rise  200  basis  points.  The  Company closely monitors its matching of earning
assets to funding sources. If core deposit levels decrease or the rate of growth
in core deposit levels does not equal or exceed the rate in growth of fixed rate
residential  real estate mortgages, the Company will reevaluate its strategy and
may  sell  new  originations  of fixed rate mortgages in the secondary market in
order  to  limit  the  Company's  exposure  to  long-term  earning  assets.

The Board of Directors and Stockholders
NBT Bancorp Inc.:

     We have audited the accompanying consolidated balance sheets of NBT Bancorp
Inc.  and  subsidiaries  as  of  December  31,  2002  and  2001, and the related
consolidated  statements of income, changes in stockholders' equity, cash flows,
and  comprehensive  income  for each of the years in the three-year period ended
December  31,  2002.  These  consolidated  financial  statements  are  the
responsibility  of the Company's management. Our responsibility is to express an
opinion  on  these  consolidated  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
consolidated  financial  statements  are free of material misstatement. An audit
includes  examining,  on  a  test  basis,  evidence  supporting  the amounts and
disclosures  in  the  consolidated  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  consolidated financial statements referred to above
present  fairly, in all material respects, the financial position of NBT Bancorp
Inc. and subsidiaries as of December 31, 2002 and 2001, and the results of their
operations  and  their cash flows for each of the years in the three-year period
ended  December  31,  2002,  in  conformity with accounting principles generally
accepted  in  the  United  States  of  America.

     As  discussed  in  Note  1  to  the  consolidated financial statements, the
Company  adopted  Statement of Financial Accounting Standards No. 142, "Goodwill
and  Other  Intangible  Assets,"  as  of January 1, 2002, and as a result ceased
amortizing  goodwill.  Also as discussed in Note 1 to the consolidated financial
statements,  the Company adopted Statement of Financial Accounting Standards No.
147, "Accounting for Certain Acquisitions of Banking or Thrift Institutions," as
of October 1, 2002, and as a result reclassified certain unidentified intangible
assets to goodwill retroactive to January 1, 2002.

                                                                        KPMG LLP
                                                                Albany, New York
                                                                January 27, 2003

NBT BANCORP INC. AND SUBSIDIARIES:
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2002 AND 2001


(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

The  accounting  and  reporting  policies  of NBT Bancorp Inc. (Bancorp) and its
subsidiaries,  NBT  Bank, N.A. (NBT Bank) NBT Financial Services, Inc., and CNBF
Capital  Trust  I,  conform,  in all material respects, to accounting principles
generally  accepted  in  the  United  States  of  America  (GAAP) and to general
practices  within  the  banking  industry.  Collectively,  Bancorp  and  its
subsidiaries  are  referred  to  herein  as  "the  Company."

     The  preparation  of  financial statements in conformity with GAAP 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 these
estimates.

     Material  estimates that are particularly susceptible to significant change
in the near term relate to the determination of the allowance for loan and lease
losses  and the valuation of other real estate owned acquired in connection with
foreclosures. In connection with the determination of the allowance for loan and
lease  losses  and  the valuation of other real estate owned, management obtains
appraisals  for  properties.

     The following is a description of significant policies and practices:


CONSOLIDATION

The  accompanying  consolidated  financial  statements  include  the accounts of
Bancorp  and  its  wholly  owned  subsidiaries.  All  material  intercompany
transactions  have been eliminated in consolidation. Amounts previously reported
in  the consolidated financial statements are reclassified whenever necessary to
conform  with  the current year's presentation. In the "Parent Company Financial
Information,"  the investment in subsidiaries is carried under the equity method
of  accounting.


SEGMENT  REPORTING

The  Company's  operations  are  primarily in the community banking industry and
include  the  provision  of  traditional  banking services. The Company operates
solely  in  the  geographical  regions  of  central  and  northern  New York and
northeastern  Pennsylvania.  The  Company  has  identified  separate  operating
segments;  however,  these segments did not meet the quantitative thresholds for
separate  disclosure.


CASH  EQUIVALENTS

The  Company  considers  amounts  due  from  correspondent  banks, cash items in
process  of  collection,  and institutional money market mutual funds to be cash
equivalents  for  purposes  of  the  consolidated  statements  of  cash  flows.


SECURITIES

The  Company  classifies  its securities at date of purchase as either available
for  sale,  held  to  maturity, or trading. Held to maturity debt securities are
those  that  the  Company  has  the  ability  and intent to hold until maturity.
Available  for  sale  securities  are recorded at fair value. Unrealized holding
gains  and  losses,  net  of  the  related  tax  effect,  on  available for sale
securities  are  excluded from earnings and are reported in stockholders' equity
as  a  component  of  accumulated  other  comprehensive  income or loss. Held to
maturity  securities  are  recorded  at  amortized  cost. Trading securities are
recorded  at  fair  value,  with  net  unrealized  gains  and  losses recognized
currently  in income. Transfers of securities between categories are recorded at
fair value at the date of transfer. A decline in the fair value of any available
for  sale  or  held  to  maturity  security  below  cost  that  is  deemed
other-than-temporary  is charged to earnings resulting in the establishment of a
new  cost basis  for  the  security.  Securities  with  an  other-than-temporary
impairment  are  generally  placed  on  nonaccrual  status.

     Nonmarketable  equity securities are carried at cost, with the exception of
investments  owned  by  NBT  Bank's  small  business  investment  company (SBIC)
subsidiary, which are carried at fair value with net unrealized gains and losses
recognized  currently  in  income  in  accordance  with  SBIC  rules.


ANNUAL REPORT: NBT BANCORP INC.                                               49

     Premiums  and  discounts  are  amortized  or  accreted over the life of the
related  security  as an adjustment to yield using the interest method. Dividend
and  interest  income  are  recognized when earned. Realized gains and losses on
securities  sold  are  derived  using  the  specific  identification  method for
determining  the  cost  of  securities  sold.

     Investments  in  Federal  Reserve  and  Federal  Home  Loan  Bank stock are
required  for  membership  in  those organizations and are carried at cost since
there  is  no  market  value  available.


LOANS AND LEASES

Loans  are  recorded  at their current unpaid principal balance, net of unearned
income  and  unamortized  loan  fees and expenses, which are amortized under the
effective interest method over the estimated lives of the loans. Interest income
on  loans  is  accrued  based  on  the  principal  amount  outstanding.

     Lease  receivables  primarily  represent  automobile financing to customers
through  direct  financing  leases and are carried at the aggregate of the lease
payments  receivable  and  the estimated residual values, net of unearned income
and  net  deferred  lease  origination  fees  and  costs.  Net  deferred  lease
origination  fees  and  costs  are amortized under the effective interest method
over  the estimated lives of the leases. The estimated residual value related to
the total lease portfolio is reviewed quarterly, and if there has been a decline
in  the  estimated  fair  value  of  the  total residual value that is judged by
management to be other-than-temporary, a loss is recognized. Adjustments related
to  such  other-than-temporary  declines in estimated fair value are recorded in
noninterest  expense  in  the  consolidated  statements  of  income.

     Loans  and leases are placed on nonaccrual status when timely collection of
principal  and  interest in accordance with contractual terms is doubtful. Loans
and  leases  are  transferred  to a nonaccrual basis generally when principal or
interest payments become ninety days delinquent, unless the loan is well secured
and  in  the  process  of  collection,  or  sooner  when  management  concludes
circumstances  indicate  that  borrowers  may  be  unable  to  meet  contractual
principal  or  interest  payments.  When  a  loan  or  lease is transferred to a
nonaccrual status, all interest previously accrued in the current period but not
collected  is  reversed against interest income in that period. Interest accrued
in  a  prior  period  and not collected is charged-off against the allowance for
loan  and  lease  losses.

     If  ultimate  repayment  of  a  nonaccrual  loan  is expected, any payments
received are applied in accordance with contractual terms. If ultimate repayment
of  principal  is  not  expected,  any  payment received on a nonaccrual loan is
applied to principal until ultimate repayment becomes expected. Nonaccrual loans
are  returned  to  accrual  status  when they become current as to principal and
interest or demonstrate a period of performance under the contractual terms and,
in  the  opinion  of  management,  are  fully  collectible  as  to principal and
interest.  When in the opinion of management the collection of principal appears
unlikely,  the  loan  balance  is  charged-off  in  total  or  in  part.

     Commercial  type loans are considered impaired when it is probable that the
borrower  will not repay the loan according to the original contractual terms of
the  loan  agreement,  and all loan types are considered impaired if the loan is
restructured  in  a  troubled  debt  restructuring.

     A  loan is considered to be a trouble debt restructured loan (TDR) when the
Company  grants a concession to the borrower because of the borrower's financial
condition  that  it  would  not otherwise consider. Such concessions include the
reduction  of  interest  rates,  forgiveness  of principal or interest, or other
modifications  at  interest rates that are less than the current market rate for
new  obligations  with similar risk. TDR loans that are in compliance with their
modified  terms  and that yield a market rate may be removed from the TDR status
after  a  period  of  performance.


ALLOWANCE FOR LOAN AND LEASE LOSSES

The  allowance  for loan and lease losses is the amount which, in the opinion of
management,  is  necessary  to  absorb  probable losses inherent in the loan and
lease portfolio. The allowance is determined based upon numerous considerations,
including  local  economic  conditions,  the  growth and composition of the loan
portfolio  with  respect to the mix between the various types of loans and their
related risk characteristics, a review of the value of collateral supporting the
loans,  comprehensive  reviews  of  the  loan  portfolio by the independent loan
review  staff  and  management, as well as consideration of volume and trends of
delinquencies,  nonperforming  loans,  and  loan charge-offs. As a result of the
test  of adequacy, required additions to the allowance for loan and lease losses
are  made  periodically  by  charges to the provision for loan and lease losses.

     The  allowance for loan and lease losses related to impaired loans is based
on discounted cash flows using the loan's initial effective interest rate or the
fair  value  of  the collateral for certain loans where repayment of the loan is
expected  to  be  provided  solely  by  the  underlying  collateral  (collateral
dependent  loans).  The  Company's  impaired  loans  are  generally  collateral
dependent.  The


50                                               ANNUAL REPORT: NBT BANCORP INC.

Company  considers  the  estimated  cost  to  sell,  on a discounted basis, when
determining  the  fair  value  of collateral in the measurement of impairment if
those  costs  are  expected  to  reduce  the  cash  flows  available to repay or
otherwise  satisfy  the  loans.

     Management  believes  that  the  allowance  for  loan  and  lease losses is
adequate.  While  management  uses  available  information to recognize loan and
lease losses, future additions to the allowance for loan and lease losses may be
necessary  based  on  changes in economic conditions or changes in the values of
properties  securing  loans  in the process of foreclosure. In addition, various
regulatory  agencies,  as  an  integral  part  of  their  examination  process,
periodically  review  the  Company's  allowance  for loan and lease losses. Such
agencies  may  require  the  Company to recognize additions to the allowance for
loan  and  lease  losses based on their judgments about information available to
them  at  the  time of their examination which may not be currently available to
management.


PREMISES  AND  EQUIPMENT

Premises  and  equipment  are  stated  at  cost,  less accumulated depreciation.
Depreciation  of  premises  and  equipment is determined using the straight-line
method  over  the  estimated useful lives of the respective assets. Expenditures
for  maintenance,  repairs,  and  minor  replacements  are charged to expense as
incurred.


OTHER  REAL  ESTATE  OWNED

Other  real  estate  owned  (OREO)  consists  of  properties  acquired  through
foreclosure  or by acceptance of a deed in lieu of foreclosure. These assets are
recorded  at  the lower of fair value of the asset acquired less estimated costs
to  sell  or  "cost"  (defined as the fair value at initial foreclosure). At the
time  of  foreclosure,  or  when foreclosure occurs in-substance, the excess, if
any,  of  the  loan  over  the  fair  market  value of the assets received, less
estimated  selling  costs,  is  charged to the allowance for loan losses and any
subsequent  valuation  write-downs are charged to other expense. Operating costs
associated  with the properties are charged to expense as incurred. Gains on the
sale  of  OREO are included in income when title has passed and the sale has met
the  minimum  down  payment  requirements  prescribed  by  GAAP.


GOODWILL  AND  OTHER  INTANGIBLE  ASSETS

Prior  to  the  adoption of Statement of Financial Accounting Standards ("SFAS")
No.  142,  Goodwill  and  Other  Intangible Assets, on January 1, 2002 (see "New
Accounting  Pronouncement-Business  Combinations,  Goodwill and Other Intangible
Assets,  and Certain Acquisitions of Banking of Thrift Institutions"), goodwill,
which  represents  the  excess  of the purchase price over the fair value of net
assets  acquired,  was  being  amortized  over 15 to 40 years on a straight-line
basis.  Other  intangible assets, which included core deposit intangible ("CDI")
and  unidentified  intangible  assets,  were being amortized over their expected
useful  lives,  which  range  from  5 to 25 years, on a straight-line basis. The
Company  reviewed  goodwill  and other intangible assets on a periodic basis for
events  or  changes  in  circumstances that may have indicated that the carrying
amount  of  goodwill  and other intangible assets were not recoverable. See "New
Accounting  Pronouncement-Business  Combinations,  Goodwill and Other Intangible
Assets,  and Certain Acquisitions of Banking of Thrift Institutions" for further
information  regarding  the  accounting for goodwill and other intangible assets
subsequent  to  December  31,  2001.


TREASURY  STOCK

Treasury  stock  acquisitions are recorded at cost. Subsequent sales of treasury
stock are recorded on an average cost basis. Gains on the sale of treasury stock
are credited to additional paid-in-capital. Losses on the sale of treasury stock
are  charged  to  additional  paid-in-capital  to  the extent of previous gains,
otherwise  charged  to  retained  earnings.


INCOME  TAXES

Income taxes are accounted for under the asset and liability method. The Company
files  a consolidated tax return on the accrual basis. Deferred income taxes are
recognized  for  the future tax consequences attributable to differences between
the  financial statement carrying amounts of existing assets and liabilities and
their  respective  tax  bases.  Deferred tax assets and liabilities are measured
using  enacted  tax  rates  expected  to apply to taxable income in the years in
which  those  temporary differences are expected to be recovered or settled. The
effect on deferred taxes of a change in tax rates is recognized in income in the
period  that  includes  the  enactment  date.


STOCK-BASED  COMPENSATION

The  Company  accounts for its stock-based compensation plans in accordance with
the  provisions  of Accounting Principles Board (APB) Opinion No. 25, Accounting
for


ANNUAL REPORT: NBT BANCORP INC.                                               51

Stock  Issued to Employees, and related interpretations. On January 1, 1996, the
Company  adopted  SFAS  No. 123,  Accounting for Stock-Based Compensation, which
permits  entities  to recognize as expense over the vesting period the estimated
fair  value  of  all  stock  based  awards  measured  on  the  date  of  grant.
Alternatively,  SFAS No. 123 allows entities to continue to apply the provisions
of  APB Opinion No. 25 and provide pro forma net income and pro forma net income
per  share  disclosures  for  employee  stock-based  grants  made  in  1995  and
thereafter  as  if  the fair value based method defined in SFAS No. 123 had been
applied.  The  Company  has  elected  to continue to apply the provisions of APB
Opinion  No.  25  and  provide  the  pro  forma  disclosures  of  SFAS  No. 123.

     At December 31, 2002, the Company has two stock option plans (Plans). Under
the  terms  of  the plans, options are granted to directors and key employees to
purchase  shares  of  the  Company's  common  stock at a price equal to the fair
market  value of the common stock on the date of the grant. Options granted have
a vesting period of four years and terminate eight or ten years from the date of
the  grant.

     The  per  share weighted average fair value of stock options granted during
2002,  2001,  and 2000 was $2.24, $3.70, and $3.35, respectively. The fair value
of  each  award  is  estimated  on  the grant date using the BlackScholes option
pricing model with the following weighted average assumptions used for grants in
the  years  ended  December  31:

     Had  the  Company  determined compensation cost based on the estimated fair

     Because  the  Company's  employee  stock  options  have  characteristics
significantly different from those of traded options for which the Black-Scholes
model was developed, and because changes in the subjective input assumptions can
materially  affect the fair value estimate, the existing models, in management's
opinion,  do not necessarily provide a reliable single measure of the fair value
of  its  employee  stock  options.

PER SHARE AMOUNTS

Basic  earnings  per  share  (EPS) excludes dilution and is computed by dividing
income available to common stockholders by the weighted average number of common
shares  outstanding  for the period. Diluted EPS reflects the potential dilution
that  could  occur  if  securities or other contracts to issue common stock were
exercised  or  converted into common stock or resulted in the issuance of common
stock  that  then  shared  in  the earnings of the entity (such as the Company's
dilutive  stock  options  and  restricted  stock).

     All  share  and  per  share  data is restated to give retroactive effect to
pooling-of-interests  and  stock  dividends.


OTHER FINANCIAL INSTRUMENTS

The  Company  is  a  party  to  certain  other  financial  instruments  with
off-balance-sheet  risk  such  as  commitments to extend credit, unused lines of
credit, and standby letters of credit, as well as certain mortgage loans sold to
investors with recourse. The Company's policy is to record such instruments when
funded.


COMPREHENSIVE INCOME

At  the  Company,  comprehensive  income  represents  net  income  plus  other
comprehensive  income,  which  consists of the net change in unrealized gains or
losses  on securities available for sale, net unrealized gains from the transfer
of  held  to maturity securities to available for sale, net of income taxes, for
the period. Accumulated other comprehensive income represents the net unrealized
gains or losses on securities available for sale, net of income taxes, as of the
consolidated  balance  sheet  dates.


PENSION COSTS

The  Company  maintains a noncontributory, defined benefit pension plan covering
substantially  all  employees, as well as supplemental employee retirement plans
covering  certain  executives.  Costs  associated  with  these  plans,  based on
actuarial computations of current and future benefits for employees, are charged
to  current  operating  expenses.


TRUST

Assets  held  by the Company in a fiduciary or agency capacity for its customers
are  not  included  in  the accompanying consolidated balance sheets, since such
assets  are not assets of the Company. Such assets totaled $1.4 billion and $1.3
billion  at December 31, 2002 and 2001, respectively. Trust income is recognized
on  the  accrual  method  based  on contractual rates applied to the balances of
trust  accounts.


NEW  ACCOUNTING  PRONOUNCEMENT-ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING
ACTIVITIES

The  Company  adopted the provisions of SFAS No. 133, "Accounting for Derivative
Instruments  and  Hedging  Activities," effective January 1, 2001. At that time,
the  Company  had  certain  embedded  derivative  instruments  from the recently
acquired  CNB Bank related to a deposit product and two debt securities that had
costs  and returns linked to the performance of the NASDAQ 100 index. Management
determined  that  these  debt securities and the deposit product did not qualify
for hedge accounting under SFAS No. 133. The embedded derivatives were separated
from  the  underlying  host  instruments  for  financial  reporting purposes and
accounted  for at fair value. In connection with the adoption of SFAS No. 133 as
of  January  1, 2001, the Company recorded a charge to earnings for a transition
adjustment  of  $159,000  ($95,000,  after-tax)  for the net impact of recording
these  embedded derivatives on the consolidated balance sheet at fair value. Due
to the insignificance of the amount, the transition adjustment was not reflected
as  a  cumulative effect of a change in accounting principle on the consolidated
statement  of  income  for  the  year  ended  December 31, 2001, but was instead
recorded  in  net  securities (losses) gains. During the year ended December 31,
2001,  and before the closing of the CNB merger, the Company recorded a $640,000
net loss related to the adjustment of the embedded derivatives to fair value. As
of December 31, 2001, the embedded derivatives referred to above were completely
written off as these derivatives had no value. During the first quarter of 2002,
the  two  debt  securities with embedded derivative instruments noted above were
sold  at  approximately their carrying value, as the securities did not meet the
risk  profile  of  the  Company's  security  portfolio.

     At  December  31,  2002,  the Company has no other derivatives as currently
defined  by  SFAS  No.  133.

NEW  ACCOUNTING  PRONOUNCEMENT-BUSINESS  COMBINATIONS,  GOODWILL  AND  OTHER
INTANGIBLE ASSETS, AND CERTAIN ACQUISITIONS OF BANKING OR THRIFT INSTITUTIONS

In  July  2001,  the FASB issued SFAS No. 141, "Business Combinations," and SFAS
No.  142.  SFAS  No. 141 requires that the purchase method of accounting be used
for  all  business  combinations  initiated  after June 30, 2001, as well as all
purchase  method  business  combinations completed after June 30, 2001. SFAS No.
141  also  specifies  criteria  intangible  assets acquired in a purchase method
business  combination  must  meet  to  be  recognized  and  reported  apart from
goodwill.  SFAS  No.  142  requires  that  goodwill  and  intangible assets with
indefinite  useful  lives  no  longer  be  amortized,  but  instead  tested  for
impairment  at least annually in accordance with the provisions of SFAS No. 142.
SFAS  No. 142 also requires that intangible assets with definite useful lives be
amortized  over  their  respective  estimated  useful  lives  to their estimated
residual  values,  and  reviewed for impairment in accordance with SFAS No. 144,
accounting  for  the  impairment  or  disposal  of  long-lived  assets.

     The  Company adopted the provisions of SFAS No. 141 effective July 1, 2001,
and  adopted  the provisions of SFAS No. 142 effective January 1, 2002. SFAS No.
141  requires  that upon adoption of SFAS No. 142, that the Company evaluate its
existing  intangible  assets and goodwill that were acquired in a prior purchase
business  combination,  and  to make any necessary reclassifications in order to
conform  with  the  new  criteria  in  SFAS  No.  141 for recognition apart from
goodwill.

     During  the first quarter of 2002, upon the implementation of SFAS No. 142,
the  Company  performed  a  reevaluation  of  the  remaining useful lives of all
previously  recognized  intangible assets and found no adjustment necessary. The
Company  has  completed  its transitional goodwill impairment evaluation and has
concluded  there  is no impairment losses from the adoption of SFAS No. 142. The
Company  has  not identified any intangible assets with indefinite useful lives.

     The unidentified intangible assets acquired in the acquisition of a bank or
thrift  (including  acquisitions  of  branches),  where  the  fair  value of the
liabilities  assumed  exceeds  the  fair  value  of the assets acquired, meeting
certain  conditions  was  amortized to expense under SFAS No. 72, Accounting for
Certain  Acquisitions  of  Banking or Thrift Institutions. In October 2002, SFAS
No.  147,  Acquisitions  of  Certain  Financial  Institutions,  was issued. This
Statement  amends  SFAS  No. 72 and 144 and Financial Accounting Standards Board
(FASB)  Interpretation  FIN  No.  9. Except for transactions between two or more
mutual  enterprises,  this  Statement  removes  acquisitions  of  financial
institutions  from the scope of both SFAS No. 72 and FIN No. 9 and requires that
those transactions be accounted for in accordance with SFAS No. 141 and No. 142.
Accordingly, unidentified intangibles related to certain branch acquisitions are
no longer amortized but are subject to impairment testing under SFAS No. 142. In
addition,  this  Statement amends SFAS No. 144 to include in its scope long-term
customer-relationship  intangible  assets  of  financial  institutions  such  as
depositor  and  borrower-relationship  intangible  assets  and credit cardholder
intangible assets. Consequently, those intangible assets are subject to the same
undiscounted  cash  flow recoverability test and impairment loss recognition and
measurement  provisions  that  SFAS No. 144 requires for other long-lived assets
that  are  held  and  used. The Statement is effective after September 30, 2002,
with the application of its provisions applied retroactively to January 1, 2002.
Upon  adoption  of  SFAS No. 142, the Company is required to reassess the useful
lives and residual values of all intangible assets acquired in purchase business
combinations,  and make any necessary amortization period adjustments by the end
of  the  first  interim  period  after  adoption.  In addition, to the extent an
intangible  asset is identified as having an indefinite useful life, the Company
is  required  to test the intangible asset for impairment in accordance with the
provisions  of  Statement  142  within  the  first  interim  period. Goodwill is
required  to  be  tested  for  impairment  by  the  end of 2002, with impairment
adjustments,  if  any,  recorded  as  of  the  beginning  of  2002.

     Note  8  provides  further  detail on the accounting for goodwill and other
intangible  assets under the standards set forth by SFAS No. 142 and No. 147 and
the  impact  on  the  adoption  on  the  consolidated  financial  statements.

NEW ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS

On August 16, 2001, the FASB issued SFAS No. 143 Accounting for Asset Retirement
Obligations.  Statement  143  addresses  financial  accounting and reporting for
obligations  associated  with  retirement  of tangible long-lived assets and the
associated  asset  retirement costs. Statement 143 applies to all entities. This
Statement  requires  that  the fair value of a liability for an asset retirement
obligation  be  recognized in the period in which it is incurred if a reasonable
estimate  of  fair  value can be made. The associated asset retirement costs are
capitalized  as  part of the carrying amount of the long-lived asset. Under this
Statement,


54                                               ANNUAL REPORT: NBT BANCORP INC.

the  liability  is  discounted and the accretion expense is recognized using the
credit-adjusted  risk-free  interest  rate  in  effect  when  the  liability was
initially  recognized. The FASB issued this Statement to provide consistency for
the  accounting  and  reporting of liabilities associated with the retirement of
tangible  long-lived  assets  and  the  associated  asset  retirement costs. The
Statement  is  effective  for  financial  statements  issued  for  fiscal  years
beginning  after  June  15,  2002. Earlier application is permitted. The Company
does  not expect a material impact on its consolidated financial statements when
this  Statement  is  adopted.


NEW  ACCOUNTING  PRONOUNCEMENT-ACCOUNTING  FOR  THE  IMPAIRMENT  OR  DISPOSAL OF
LONG-LIVED  ASSETS

On  October  3, 2001, The FASB issued SFAS No. 144 Accounting for the Impairment
or  Disposal of Long-Lived Assets. This Statement addresses financial accounting
and  reporting  for  the  impairment  or  disposal  of  long-lived  assets. This
Statement  supersedes  SFAS  No. 121 Accounting for the Impairment of Long-Lived
Assets  and  for  Long-Lived  Assets  to  be  Disposed  Of.  This Statement also
supersedes  the  accounting  and  reporting  provisions  of  APB  Opinion No. 30
Reporting  the  Results  of  Operations-Reporting  the  Effects of Disposal of a
Segment  of  a  Business,  and Extraordinary, Unusual and Infrequently Occurring
Events  and  Transactions.  The  changes  in  this  Statement  improve financial
reporting  by  requiring that one accounting model be used for long-lived assets
to  be  disposed of by broadening the presentation of discontinued operations to
include  more  disposal  transactions. This Statement is effective for financial
statements issued for fiscal years beginning after December 15, 2001 and interim
periods  within  those  fiscal years. The Company adopted the provisions of SFAS
No.  144  effective  January  1,  2002, and the adoption did not have a material
impact  on  its  consolidated  financial  statements.


NEW ACCOUNTING PRONOUNCEMENT-RESCISSION OF FASB STATEMENTS NO. 4, 44 AND 64

In  April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No.
4,  44,  and 64, Amendment of FASB Statement No. 13, and Technical Corrections."
SFAS  No.  145  rescinds  SFAS  No.  4,  "Reporting  Gains  and  Losses  from
Extinguishment  of Debt," which required gains and losses from extinguishment of
debt to be aggregated and, if material, classified as an extraordinary item, net
of  related  income tax effect. Upon adoption of SFAS No. 145, companies will be
required  to  apply the criteria in Accounting Principles Board, or APB, Opinion
No.  30,  "Reporting the Results of Operations-Reporting the Effects of Disposal
of  a  Segment  of  a  Business,  and  Extraordinary,  Unusual  and Infrequently
Occurring  Events  and  Transactions" in determining the classification of gains
and  losses  resulting from the extinguishment of debt. Upon adoption, companies
must  reclassify  prior  period  items  that  do not meet the extraordinary item
classification criteria in APB Opinion No. 30. Additionally, SFAS No. 145 amends
SFAS  No.  13,  "Accounting  for  Leases,"  to  require  that  certain  lease
modifications  that have economic effects similar to sale-leaseback transactions
be  accounted  for  in  the  same  manner  as  sale-leaseback  transactions. The
provisions of SFAS No. 145 related to the rescission of SFAS No. 4 are effective
for  fiscal years beginning after May 15, 2002. All other provisions of SFAS No.
145  are effective for transactions occurring and/or financial statements issued
on  or  after May 15, 2002. The implementation of SFAS No. 145 provisions, which
were  effective May 15, 2002, did not have a material impact on our consolidated
financial  condition  or  results  of  operations.  The  implementation  of  the
remaining  provisions  is  not  expected  to  have  a  material  impact  on  our
consolidated  financial  condition  or  results  of  operations.


NEW  ACCOUNTING  PRONOUNCEMENT-ACCOUNTING  FOR  COSTS  ASSOCIATED  WITH  EXIT OR
DISPOSAL  ACTIVITIES

In  June  2002,  the  FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities." This Statement addresses financial accounting
and  reporting  for  costs  associated  with  exit  or  disposal  activities and
nullifies  Emerging  Issues  Task  Force  (EITF)  Issue  No.  94-3,  "Liability
Recognition for Certain Employee Termination Benefits and Other Costs to Exit an
Activity  (including Certain Costs Incurred in a Restructuring)." This Statement
is  effective for exit or disposal activities initiated after December 31, 2002.
The  Company  will  review  the  impact of applying this standard to any exit or
disposal  activities  initiated  after  December  31,  2002.


NEW ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR STOCK BASED COMPENSATION

In  December  2002,  the  FASB  issued SFAS No. 148, "Accounting for Stock-Based
Compensation-Transition  and  Disclosure,"  which  provides  guidance  on how to
transition  from  the  intrinsic  value  method  of  accounting  for


ANNUAL REPORT: NBT BANCORP INC.                                               55

stock-based  employee compensation under APB No. 25 to SFAS No. 123's fair value
method  of  accounting, if a company so elects. The Company currently intends to
continue  to  account  for stock-based employee compensation under APB No. 25 in
2003.


NEW ACCOUNTING PRONOUNCEMENT-ACCOUNTING FOR GUARANTEES

In  November  2002,  the  FASB  issued  FASB  Interpretation  No.  45  (FIN 45),
"Guarantor's  Accounting  and  Disclosure Requirements for Guarantees, Including
Indirect  Guarantees of Indebtedness of Others." This interpretation expands the
disclosures  to  be  made  by  a guarantor in its financial statements about its
obligations  under  certain guarantees and requires the guarantor to recognize a
liability  for the fair value of an obligation assumed under a guarantee. FIN 45
clarifies  the  requirements  of  SFAS  No.  5,  "Accounting for Contingencies,"
relating  to  guarantees.  In  general,  FIN  45  applies  to  contracts  or
indemnification  agreements  that  contingently  require  the  guarantor to make
payments  to  the  guaranteed  party  based  on changes in an underlying that is
related  to  an  asset,  liability,  or equity security of the guaranteed party.
Certain  guarantee  contracts  are  excluded  from  both  the  disclosure  and
recognition  requirements  of  this  interpretation,  including,  among  others,
guarantees  relating  to  employee compensation, residual value guarantees under
capital  lease  arrangements,  commercial  letters  of credit, loan commitments,
subordinated  interests  in  an  a  special  purpose entity, and guarantees of a
company's own future performance. Other guarantees are subject to the disclosure
requirements  of FIN 45 but not to the recognition provisions and include, among
others, a guarantee accounted for as a derivative instrument under SFAS No. 133,
a  parent's  guarantee  of  debt owed to a third party by its subsidiary or vice
versa,  and  a guarantee which is based on performance not price. The disclosure
requirements  of  FIN  45 are effective for the Company as of December 31, 2002,
and  require  disclosure  of  the nature of the guarantee, the maximum potential
amount of future payments that the guarantor could be required to make under the
guarantee,  and the current amount of the liability, if any, for the guarantor's
obligations  under  the guarantee. The recognition requirements of FIN 45 are to
be  applied  prospectively  to  guarantees issued or modified after December 31,
2002.  The  requirements  of  FIN  45  will  not  have  a material impact on the
Company's  consolidated results of operations, financial position, or liquidity.


NEW ACCOUNTING PRONOUNCEMENT-CONSOLIDATION OF VARIABLE INTEREST ENTITIES

In  January  2003,  the  FASB  issued  FASB  Interpretation  No.  46  (FIN  46),
"Consolidation  of  Variable  Interest  Entities."  The  objective  of  this
interpretation  is  to  provide  guidance on how to identify a variable interest
entity  (VIE)  and  determine  when  the  assets,  liabilities,  noncontrolling
interests, and results of operations of a VIE need to be included in a company's
consolidated financial statements. A company that holds variable interests in an
entity  will need to consolidate the entity if the company's interest in the VIE
is  such  that  the  company will absorb a majority of the VIE's expected losses
and/or  receive  a  majority  of the entity's expected residual returns, if they
occur.  FIN 46 also requires additional disclosures by primary beneficiaries and
other  significant  variable  interest  holders.  The  provisions  of  this
interpretation  became  effective upon issuance. The requirements of FIN 46 will
not  have a material impact on the Company's consolidated results of operations,
financial  position,  or  liquidity.


(2)  MERGER AND ACQUISITION ACTIVITY
- --------------------------------------------------------------------------------

The  Company  did  not  enter  into  any  mergers  or  acquisitions during 2002.

     On  June  1,  2001, the Company completed the acquisition of First National
Bancorp, Inc. (FNB) whereby FNB was merged with and into NBT Bancorp Inc. At the
same  time FNB's subsidiary, First National Bank of Northern New York (FNB Bank)
was  merged  into  NBT Bank, N.A.  The  acquisition  was accounted for using the
purchase  method.  As  such,  both  the assets and liabilities assumed have been
recorded  on  the  consolidated  balance  sheet of the Company at estimated fair
value  as  of the date of acquisition and the results of operations are included
in  the  Company's  consolidated  statement  of income from the acquisition date
forward. To complete the transaction, the Company issued approximately 1,075,000
shares  of  its common stock valued at $16.0 million. Goodwill, representing the
cost  over  net  assets  acquired,  was approximately $7.0 million and was being
amortized  prior  to  the  adoption  of  SFAS  No.  142  on January 1, 2002 on a
straight-line  basis  based  on  a  twenty  year  amortization  period.

     On September 14, 2001, the Company acquired


56                                               ANNUAL REPORT: NBT BANCORP INC.

$14.4  million  in  deposits from Mohawk Community Bank. Unidentified intangible
assets, accounted for in accordance with SFAS No. 72 and representing the excess
of  cost  over  net assets acquired, was $665,000 and is being amortized over 15
years on a straight-line basis. Additionally, the Company identified $119,000 of
core  deposit  intangible  asset  which  is  being  amortized  over 6 years on a
straight-line  basis.

     On November 8, 2001, the Company, pursuant to a merger agreement dated June
18,  2001,  completed  its  merger with CNB Financial Corp. (CNB) and its wholly
owned  subsidiary, Central National Bank (CNB Bank), whereby CNB was merged with
and  into  NBT,  and  CNB  Bank was merged with and into NBT Bank. CNB Bank then
became  a  division of NBT Bank. In connection with the merger, CNB stockholders
received  1.2  shares  of the Company's common stock for each share of CNB stock
and  the  Company  issued  approximately 8.9 million shares of common stock. The
transaction  is  structured  to  be tax free to shareholders of CNB and has been
accounted for as a pooling-of-interests. Accordingly, the Company's consolidated
financial  statements  were  restated to present combined consolidated financial
condition  and results of operations of NBT and CNB as if the merger had been in
effect  for  all  years  presented.  At September 30, 2001, CNB had consolidated
assets  of  $983.1  million,  deposits  of  $853.7  million, and equity of $62.8
million.  CNB  Bank operated 29 full service banking offices in nine upstate New
York  counties.

     On  February 17, 2000, the Company consummated a merger, whereby Lake Ariel
Bancorp,  Inc.  (Lake  Ariel) and its subsidiaries were merged with and into the
Company  with  each  issued  and  outstanding  share of Lake Ariel exchanged for
0.9961  shares of Bancorp common stock. The transaction resulted in the issuance
of  approximately  5.0  million  shares  of  Bancorp  common stock. Lake Ariel's
commercial  banking  subsidiary  was  LA  Bank,  N.A.

     On July 1, 2000, the Company consummated a merger, whereby Pioneer American
Holding  Company  Corp. (Pioneer Holding Company) and its subsidiary were merged
with  and  into  the  Company  with each issued and outstanding share of Pioneer
Holding  Company  exchanged  for  1.805  shares  of  Bancorp  common  stock. The
transaction  resulted  in  the  issuance  of approximately 5.2 million shares of
Bancorp  common  stock.  Pioneer Holding Company's commercial banking subsidiary
was  Pioneer  American  Bank,  N.A.

     The  Lake  Ariel  and Pioneer Holding Company mergers qualified as tax-free
exchanges  and  were  accounted  for  as poolings-of-interests. Accordingly, the
Company's  consolidated  financial  statements  were  restated  to  present  the
combined  consolidated  financial  condition  and  results  of operations of all
companies  as  if  the  mergers  had  been  in  effect  for all years presented.

     LA  Bank, N.A. and Pioneer Bank N.A. were commercial banks headquartered in
northeast  Pennsylvania  with  approximately  $570  million  and  $420  million,
respectively, in assets at December 31, 1999, and twenty-two and eighteen branch
offices,  respectively,  in  five counties. Immediately following the Lake Ariel
and  Pioneer  Holding Company mergers described above, Bancorp was the surviving
holding company for NBT Bank, LA Bank, N.A., Pioneer American Bank, N.A. and NBT
Financial Services, Inc. On November 10, 2000, LA Bank, N.A. changed its name to
Pennstar.  On  December  9,  2000,  Pioneer  American Bank, N.A. was merged into
Pennstar.  On  March  16,  2001,  Pennstar was merged with and into NBT Bank and
became  a  division  of  NBT  Bank.

     On  May  5,  2000,  the Company consummated the acquisition of M. Griffith,
Inc.  a  Utica,  New  York  based securities firm offering investment, financial
advisory  and  asset-management services, primarily in the Mohawk Valley region.
At  that  time, M. Griffith, Inc., a full-service broker/dealer and a Registered
Investment  Advisor, became a wholly owned subsidiary of NBT Financial Services,
Inc.  The acquisition was accounted for using the purchase method. As such, both
the  assets  acquired  and  liabilities  assumed  have  been  recorded  on  the
consolidated balance sheet of the Company at estimated fair value as of the date
of  acquisition.  M. Griffith, Inc.'s, results of operations are included in the
Company's consolidated statement of income from the date of acquisition forward.
To  complete the transaction, the Company issued approximately 421,000 shares of
its  common  stock, valued at $4.8 million. Goodwill, representing the cost over
net  assets  acquired,  was  $3.4  million and was being amortized, prior to the
adoption  of  SFAS  No.  142  on  January  1,  2002,  over  fifteen  years  on a
straight-line  basis.

     On June 2, 2000, one of Bancorp's subsidiaries, LA Bank, N.A. (subsequently
renamed  Pennstar),  purchased  two branches from Mellon Bank. Deposits from the
Mellon  Bank  branches  were  approximately  $36.7  million,  including  accrued
interest  payable. In addition, the Company received approximately $32.2 million
in  cash  as  consideration  for  net  liabilities  assumed. The acquisition was
accounted  for  using the purchase method. As such, both the assets acquired and
liabilities  assumed have been recorded on the consolidated balance sheet of the
Company  at estimated fair value as of the date of the acquisition. Unidentified
intangible assets, accounted for in accordance with SFAS No. 72 and representing
the  excess

of  cost over net assets acquired, was $4.3 million and was being amortized over
15  years  on  the  straight-line basis prior to the adoption of SFAS No. 147 on
January  1,  2002.  The  branches'  results  of  operations  are included in the
Company's consolidated statement of income from the date of acquisition forward.

     On  November  10, 2000, Pennstar purchased six branches from Soverign Bank.
deposits  from  the  Soverign  Bank  branches  were approximately $96.8 million,
including  accrued  interest  payable.  Pennstar also purchased commercial loans
associated  with  the  branches  with  a  net  book balance of $42.4 million. In
addition,  the  Company  received  $40.9  million  in cash consideration for net
liabilities  assumed.  The  acquisition  was  accounted  for  using the purchase
method.  As  such,  both  the  assets acquired and liabilities assumed have been
recorded  on  the  consolidated  balance  sheet of the Company at estimated fair
value  as  of  the  date  of  the  acquisition.  Unidentified intangible assets,
accounted for in accordance with SFAS No. 72 and representing the excess of cost
over  net  assets  acquired,  was  $12.7 million and was being amortized over 15

January  1,  2002.  The  branches'  results  of  operations  are included in the
Company's consolidated statement of income from the date of acquisition forward.

     The  security  with other-than-temporary impairment charges at December 31,
2002  had  a  remaining  carrying  value, which approximated fair value, of $1.1
million,  is  classified  as  securities  available  for  sale  and  is  on  the
non-accrual  status.

     Approximately,  $1.4  million of the other-than temporary impairment charge
in  2000  related  to  the  Company's decision in late 2000 to sell certain debt
securities  available  for  sale  with  an amortized cost of $21.7 million. As a
result  of  the  decision  to  immediately  sell  these  securities,  they  were
considered  to be other than-temporarily impaired. These securities were sold in
early January 2001 at amounts approximating their carrying values. The remaining
securities with other than temporary impairment charges at December 31, 2000 had
carrying  values  totaling  $1.4  million,  which  approximated  fair  value, at
December  31,  2000,  are classified as securities available for sale and are on
the  non-accrual  status.

     At December 31, 2002 and 2001, securities available for sale with amortized
costs  totaling $519.7 million and $628.8 million, respectively, were pledged to
secure  public  deposits  and  for  other purposes required or permitted by law.
Additionally,  at  December  31,  2002,  securities  available  for sale with an
amortized  cost  of $51.9 million were pledged as collateral for securities sold
under  repurchase  agreements.

     The  amortized  cost, estimated fair value, and unrealized gains and losses
of securities held to maturity are as follows:

1,  2002,  with  retroactive  application to January 1, 2002, the Company ceased

(11) LONG-TERM DEBT
- --------------------------------------------------------------------------------

Long-term  debt  consists of obligations having an original maturity at issuance
of  more  than one year. A majority of the Company's long-term debt is comprised
of  FHLB advances collateralized by the FHLB stock owned by the Company, certain
of  its  mortgage-backed  securities  and a blanket lien on its residential real
estate mortgage loans. A summary as of December 31, 2002 is as follows:

(12)  GUARANTEED PREFERRED BENEFICIAL INTERESTS IN COMPANY'S JUNIOR SUBORDINATED
DEBENTURES
- --------------------------------------------------------------------------------

On  June  14, 1999, CNB established CNBF Capital Trust I (the Trust), which is a
statutory  business trust. The Trust exists for the exclusive purpose of issuing
and  selling  30 year guaranteed preferred beneficial interests in the Company's
junior  subordinated  debentures  (capital  securities).  On August 4, 1999, the
Trust issued $18.0 million in capital securities at 3-month LIBOR plus 275 basis
points,  which  equaled  8.12%  at  issuance. The rate on the capital securities
resets  quarterly,  equal  to the 3-month LIBOR plus 275 basis points (4.55% and
5.35%  for the December 31, 2002 and 2001 quarterly payments, respectively). The
capital securities are the sole asset of the Trust. The obligations of the Trust
are  guaranteed by Bancorp. Capital securities totaling $1.0 million were issued
to  NBT.  These  capital  securities were retired upon the merger of NBT and CNB
(see note 2). The net proceeds from the sale of the capital securities were used
for  general  corporate  purposes and to provide a capital contribution of $15.0
million  to  CNB  Bank,  which was merged into NBT Bank. The capital securities,
with  associated expense that is tax deductible, qualify as Tier I capital under
regulatory  definitions,  subject to certain restrictions. The Bancorp's primary
source  of funds to pay interest on the debentures owed to the Trust are current
dividends  from  the NBT Bank. Accordingly, the Bancorp's ability to service the
debentures  is dependent upon the continued ability of NBT Bank to pay dividends
(see  also  note  14).  The  capital  securities  are not classified as debt for
financial  statement  purposes  and  therefore  the  expense associated with the
capital  securities  is  recorded  as  non-interest  expense in the consolidated
statements  of  income.

     The  above  table  does  not include the recorded deferred tax liability of
$11.0  million  as of December 31, 2002 and $2.6 million as of December 31, 2001
related  to  the  net  unrealized  holding  gain/loss  in the available-for-sale
securities  portfolio.

     Realization  of  deferred  tax  assets  is dependent upon the generation of
future  taxable  income or the existence of sufficient taxable income within the
available  carryback  period.  A valuation allowance is provided when it is more
likely  than  not  that  some  portion  of  the  deferred  tax asset will not be
realized. Based on available evidence, gross deferred tax assets will ultimately
be  realized  and a valuation allowance was not deemed necessary at December 31,
2002  and  2001.

     At  December 31, 2002, the Company has Federal and state net operating loss
carryforwards  of  $410,000  and


ANNUAL REPORT: NBT BANCORP INC.                                               69

$292,000, respectively, which expire in 2021. At December 31, 2002 and 2001, the
Company  had  alternative  minimum  tax  credit  carryforward  of  $164,000  and
$521,000,  respectively,  which  may  be  carried  forward  indefinitely.  The
utilization  of  the  tax  net operating loss and alternative minimum tax credit
carryforwards  is  subject  to limitations imposed by the Internal Revenue Code.
The  Company  believes  these  limitations  will  not  prevent  the carryforward
benefits  from  being  realized.  At  December  31, 2002, the Company also has a
capital  loss  carryforward  of  $1,436,000  which  expires  in  2007.

     The  following is a reconciliation of the provision for income taxes to the
amount  computed  by  applying  the  applicable Federal statutory rate of 35% to
income  before  taxes:

(14) STOCKHOLDERS' EQUITY
- --------------------------------------------------------------------------------

Certain  restrictions  exist  regarding  the  ability  of the subsidiary bank to
transfer funds to the Company in the form of cash dividends. The approval of the
Office  of Comptroller of the Currency (OCC) is required to pay dividends when a
bank  fails  to  meet  certain minimum regulatory capital standards or when such
dividends  are in excess of a subsidiary bank's earnings retained in the current
year  plus  retained  net profits for the preceding two years (as defined in the
regulations).  At  December  31,  2002,  approximately $9.8 million of the total
stockholders'  equity  of the Bank was available for payment of dividends to the
Company without approval by the OCC. The Bank's ability to pay dividends also is
subject  to  the  Bank being in compliance with regulatory capital requirements.
The  Bank is currently in compliance with these requirements. Under the State of
Delaware  Business  Corporation  Law,  the Company may declare and pay dividends
either  out  of  accumulated  net  retained  earnings  or  capital  surplus.

     In  November  1994,  the  Company  adopted a Stockholder Rights Plan (Plan)
designed to ensure that any potential acquirer of the Company negotiate with the
board  of  directors  and that all Company stockholders are treated equitably in
the  event  of  a takeover attempt. At that time, the Company paid a dividend of
one  Preferred Share Purchase Right (Right) for each outstanding share of common
stock of the Company. Similar rights are attached to each share of the Company's
common stock issued after November 15, 1994. Under the Plan, the Rights will not
be  exercisable  until a person or group acquires beneficial ownership of 20% or
more  of  the  Company's  outstanding  common stock, begins a tender or exchange
offer  for  25% or more of the Company's outstanding common stock, or an adverse
person,  as  declared  by  the  board  of directors, acquires 10% or more of the
Company's  outstanding  common stock. Additionally, until the occurrence of such
an  event,  the  Rights  are  not severable from the Company's common stock and,
therefore,  the  Rights  will  be transferred upon the transfer of shares of the
Company's  common stock. Upon the occurrence of such events, each Right entitles
the holder to purchase one one-hundredth of a share of Series R Preferred Stock,
no  par  value,  and  $0.01  stated value per share of the Company at a price of
$100.

     The  Plan  also  provides  that  upon  the  occurrence of certain specified
events,  the  holders  of  Rights  will be entitled to acquire additional equity
interests,  in  the  Company or in the acquiring entity, such interests having a


70                                               ANNUAL REPORT: NBT BANCORP INC.

market  value of two times the Right's exercise price of $100. The Rights, which
expire  November  14,  2004,  are  redeemable  in whole, but not in part, at the
Company's  option  prior  to the time they are exercisable, for a price of $0.01
per  Right.


(15) REGULATORY CAPITAL REQUIREMENTS
- --------------------------------------------------------------------------------

Bancorp  and  NBT  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 consolidated financial statements. Under capital adequacy
guidelines  and  the regulatory framework for prompt corrective action, NBT Bank
must  meet specific capital guidelines that involve quantitative measures of NBT
Bank's  assets,  liabilities,  and certain off-balance sheet items as calculated
under  regulatory  accounting practices. The capital amounts and classifications
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 the NBT Bank's to maintain minimum amounts and ratios
(set  forth  in  the  table below)  of total and Tier 1 Capital to risk-weighted
assets,  and  of  Tier  1 capital to average assets. As of December 31, 2002 and
2001,  the  Company and NBT Bank meet all capital adequacy requirements to which
they  were  subject.

     Under  their  prompt  corrective action regulations, regulatory authorities
are  required  to  take  certain  supervisory  actions  (and may take additional
discretionary  actions)  with  respect  to an undercapitalized institution. Such
actions  could  have  a  direct  material  effect  on an institution's financial
statements.  The  regulations  establish  a  framework for the classification of
banks  into  five  categories:  well  capitalized, adequately capitalized, under
capitalized,  significantly under capitalized, and critically under capitalized.
As of December 31, 2002, the most recent notification from NBT Bank's regulators
categorized  NBT  Bank  as  well  capitalized under the regulatory framework for
prompt  corrective  action.  To be categorized as well capitalized NBT Bank must
maintain  minimum total risk-based, Tier 1 risk-based, Tier 1 capital to average
asset  ratios as set forth in the table. There are no conditions or events since
that  notification  that  management  believes have changed NBT Bank's category.

(16) EMPLOYEE BENEFIT PLANS
- --------------------------------------------------------------------------------

PENSION PLAN

The  Company  has  a  qualified,  noncontributory,  defined benefit pension plan
covering  substantially  all of its employees at December 31, 2001. M. Griffith,
Inc.  and  the  former  Pennstar  (and  its  predecessors Lake Ariel and Pioneer
Holding  Company)  did  not  provide  for  pension benefits to employees through
January  1,  2001.  As  such,  M.  Griffith, Inc. and Pennstar employees are not
included  in  this  plan  at  December  31, 2000. M. Griffith, Inc. and Pennstar
employees began to participate and accrue benefits under this plan as of January
1,  2001.  No benefit credit was provided in the Company's plan for service with
M.  Griffith,  Inc.  and the former Pennstar (and its predecessors Lake Ariel or
Pioneer Holding Company). Benefits paid from the plan are based on age, years of
service,  compensation,  social  security  benefits,  and  are  determined  in
accordance  with  defined  formulas. The Company's policy is to fund the pension
plan  in  accordance  with  ERISA  standards. Assets of the plan are invested in
publicly  traded  stocks and bonds. Prior to January 1, 2000, the Company's plan
was  a  traditional defined benefit plan based on final average compensation. On
January  1,  2000,  the  plan  was  converted  to  a  cash  balance  plan  with
grandfathering  provisions  for  existing  participants.

     Prior  to  December  31,  2001,  the Company maintained two noncontributory
defined  benefit  retirement plans, the NBT Bancorp Inc. Defined Benefit Pension
Plan and the Central National Bank, Canajoharie Pension Plan. Effective December
31,  2001,  the  Company  merged  those  two  plans.

     The  net  periodic pension expense and the funded status of the plan are as
follows:

benefits.  The  plan  is  contributory  for  participating  retirees,  requiring
participants  to  absorb  certain  deductibles  and  coinsurance  amounts  with
contributions  adjusted  annually to reflect cost sharing provisions and benefit
limitations called for in the plan. Employees become eligible for these benefits
if  they  reach normal retirement age while working for the Company. The Company
funds  the  cost of postretirement health care as benefits are paid. The Company
elected  to  recognize  the transition obligation on a delayed basis over twenty
years.

(17) COMMITMENTS AND CONTINGENT LIABILITIES
- --------------------------------------------------------------------------------

The  Company's  concentrations  of credit risk are reflected in the consolidated
balance  sheets.  The  concentrations  of  credit  risk  with standby letters of
credit,  unused  lines  of  credit, commitments to originate new loans and loans
sold  with  recourse  generally  follow  the  loan  classifications.

     At  December 31, 2002, approximately 62% of the Company's loans are secured
by  real  estate  located  in  central  and  northern  New York and northeastern
Pennsylvania.  Accordingly, the ultimate collectibility of a substantial portion
of  the  Company's  portfolio  is susceptible to changes in market conditions of
those areas. Management is not aware of any material concentrations of credit to
any  industry  or  individual  borrowers.

     The  Company  is  a party to certain financial instruments with off balance
sheet  risk  in the normal course of business to meet the financing needs of its
customers.  These  financial  instruments  include commitments to extend credit,
unused lines of credit, standby letters of credit, and as certain mortgage loans
sold  to  investors  with recourse. The Company's exposure to credit loss in the
event  of nonperformance by the other party to the commitments to extend credit,
unused  lines of credit, standby letters of credit, and loans sold with recourse
is  represented by the contractual amount of those instruments. The Company uses
the  same  credit standards in making commitments and conditional obligations as
it  does  for  on  balance  sheet  instruments.



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

Standby letters of credit                                  24,659    20,984

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


     The  total  amount  of  loans  serviced  by the Company for unrelated third
parties  was  approximately $77.2 million and $93.2 million at December 31, 2002
and  2001,  respectively.

     In  the  normal  course  of  business  there  are various outstanding legal
proceedings. In the opinion of management, the aggregate amount involved in such
proceedings  is  not  material  to the consolidated balance sheets or results of
operations  of  the  Company.

     In  November  2002,  the  FASB  issued FASB Interpretation No. 45 ("FIN No.
45"),  "Guarantor's  Accounting  and  Disclosure  Requirements  for  Guarantees,
Including  Indirect  Guarantees  of Indebtedness of Others; an Interpretation of
FASB  Statements  No.  5,  57, and 107 and rescission of FASB Interpretation No.
34."  FIN  No.  45  requires  certain  new  disclosures  and  potential
liability-recognition  for  the  fair  value at issuance of guarantees that fall
within  its  scope.  Under FIN No. 45, the Company does not issue any guarantees
that  would  require liability-recognition or disclosure, other than its standby
letters  of  credit.

     The  Company  guarantees  the  obligations  or  performance of customers by
issuing  stand-by  letters of credit to third parties. These stand-by letters of
credit  are  frequently issued in support of third party debt, such as corporate
debt  issuances,  industrial  revenue  bonds, and municipal securities. The risk
involved  in  issuing  stand-by letters of credit is essentially the same as the
credit  risk  involved  in  extending loan facilities to customers, and they are
subject  to  the  same  credit origination, portfolio maintenance and management
procedures  in  effect  to  monitor other credit and off-balance sheet products.
Typically, these instruments have terms of five years or less and expire unused;
therefore,  the  total  amounts  do  not  necessarily  represent  future  cash
requirements.

(19) FAIR VALUES OF FINANCIAL INSTRUMENTS
- --------------------------------------------------------------------------------

The  following  methods  and assumptions were used to estimate the fair value of
each  class  of  financial  instruments.


SHORT TERM INSTRUMENTS

For  short-term instruments, such as cash and cash equivalents, accrued interest
receivable,  accrued interest payable, and short term borrowings, carrying value
approximates  fair  value.


SECURITIES

Fair  values  for securities are based on quoted market prices or dealer quotes,
where  available.  Where quoted market prices are not available, fair values are
based  on  quoted  market  prices  of  comparable  instruments.


LOANS

For  variable  rate loans that reprice frequently and have no significant credit
risk,  fair  values are based on carrying values. The fair values for fixed rate
loans  are  estimated


78                                               ANNUAL REPORT: NBT BANCORP INC.

through  discounted  cash  flow  analysis  using  interest rates currently being
offered for loans with similar terms and credit quality. Nonperforming loans are
valued  based  upon  recent  loss  history  for  similar  loans.


DEPOSITS

The  fair  values  disclosed  for savings, money market, and noninterest bearing
accounts  are,  by  definition,  equal to their carrying values at the reporting
date.  The  fair  value  of  fixed  maturity  time deposits is estimated using a
discounted cash flow analysis that applies interest rates currently offered to a
schedule  of  aggregated  expected  monthly  maturities  on  time  deposits.


LONG-TERM  DEBT

The  fair  value of long-term debt has been estimated using discounted cash flow
analysis  that  applies  interest rates currently offered for notes with similar
terms.


COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTERS OF CREDIT

The fair value of commitments to extend credit and standby letters of credit are
estimated  using fees currently charged to enter into similar agreements, taking
into  account  the  remaining  terms  of  the  agreements and the present credit
worthiness  of  the counterparties. Carrying amounts, which are comprised of the
unamortized  fee  income,  are  not  significant.


GUARANTEED  PREFERRED  BENEFICIAL  INTERESTS  IN  COMPANY'S  JUNIOR SUBORDINATED
DEBENTURES

Given  the variable rate nature of this financial instrument, the carrying value
approximates  fair  value.

     Estimated  fair  values  of  financial  instruments  at  December 31 are as
follows:

ANNUAL REPORT: NBT BANCORP INC.                                              79

(1)  LEASE  RECEIVABLES,  ALTHOUGH  EXCLUDED FROM THE SCOPE OF SFAS NO. 107, ARE
INCLUDED  IN  THE  ESTIMATED  FAIR  VALUE  AMOUNTS  AT  THEIR  CARRYING AMOUNTS.

Fair  value  estimates  are  made at a specific point in time, based on relevant
market  information  and  information  about  the  financial  instrument.  These
estimates do not reflect any premium or discount that could result from offering
for  sale  at  one  time the Company's entire holdings of a particular financial
instrument.  Because no market exists for a significant portion of the Company's
financial  instruments,  fair  value  estimates are based on judgments regarding
future  expected  loss  experience,  current  economic  conditions,  risk
characteristics  of  various  financial  instruments,  and  other factors. These
estimates  are  subjective  in  nature  and involve uncertainties and matters of
significant  judgment and therefore cannot be determined with precision. Changes
in  assumptions  could  significantly  affect  the  estimates.

     Fair  value  estimates  are based  on  existing  on  and  off-balance-sheet
financial  instruments  without  attempting to estimate the value of anticipated
future  business and the value of assets and liabilities that are not considered
financial  instruments.  For  example,  the  Company has a substantial trust and
investment  management  operation  that contributes net fee income annually. The
trust  and  investment  management  operation  is  not  considered  a  financial
instrument,  and  its  value  has  not  been  incorporated  into  the fair value
estimates.  Other  significant  assets  and  liabilities  include  the  benefits
resulting  from  the low-cost  funding of deposit liabilities as compared to the
cost  of borrowing funds in the market, and premises and equipment. In addition,
the  tax  ramifications  related  to the realization of the unrealized gains and
losses  can  have a significant effect on fair value estimates and have not been
considered  in  the  estimate  of  fair  value.

          controls  which  could  adversely  affect  the registrant's ability to
          record,  process,  summarize  and  report  financial  data  and  have
          identified  for  the  registrant's auditors any material weaknesses in
          internal  controls;  and
     b)   Any  fraud, whether or not material, that involves management or other
          employees  who  have  a  significant role in the registrant's internal
          controls;  and
6.   The  registrant's  other  certifying  officer  and I have indicated in this
     annual  report  whether  or  not there were significant changes in internal
     controls  or  in  other  factors  that  could significantly affect internal
