                                     PART I

ITEM 1.    BUSINESS

GENERAL  DEVELOPMENT  OF  BUSINESS
     Tompkins County Trustco,  Inc. (the "Company") was  incorporated  under the
laws of the State of New York on March 6, 1995,  and is a bank  holding  company
registered with the Federal Reserve Board ("FRB") under the Bank Holding Company
Act of  1976,  as  amended.  The  principal  offices  of  the  Company  and  its
wholly-owned  operating subsidiary,  Tompkins County Trust Company ("the Bank"),
are located at The  Commons,  P.O.  Box 460,  Ithaca,  New York  14851,  and its
telephone number is 607-273-3210. The Bank is a commercial bank chartered in New
York State, which has operated in the community of Ithaca, New York and environs
since 1836.

     On January 1, 1996, the Company consummated a corporate reorganization (the
"Reorganization") pursuant to which, the Company became the sole shareholder of,
and holding company for, the Bank. All outstanding shares of common stock of the
Bank were converted,  on a one-for-one basis, into all of the outstanding shares
of common stock of the Company. As a result of the Reorganization, the Company's
primary asset is the common stock of its wholly-owned subsidiary, the Bank.

     The  Company  engages  in no  substantial  business  activities  other than
activities  related to its ownership of the Bank.  Unless the context  otherwise
requires,  all  references  herein to the  "Company"  include  its  wholly-owned
operating subsidiary, the Bank.

STOCK  REPURCHASE  TRANSACTIONS
     In October 1996, the Company  repurchased  244,371 shares of its own common
stock in a privately  negotiated sale from an unrelated  third party.  The stock
was purchased at a price of $27.50 per share, for a total purchase price of $6.7
million.  The shares have been returned to the status of authorized and unissued
shares.  In May 1997,  the  Company  repurchased  80,000  shares in a  privately
negotiated  transaction.  The shares,  which have been returned to the status of
authorized but unissued, were purchased at $33.38 per share for a total purchase
price of $2.67 million.

     In  November  1996,  the board of  directors  approved  a stock  repurchase
program,  which authorizes the repurchase of up to $3 million in common stock in
open market transactions.  No open market transactions have been completed under
this program.

BRANCH ACQUISITION
     In November 1996, the Bank acquired all deposits and selected assets of the
Odessa branch office of the First National Bank of Rochester. The acquisition of
the Odessa office,  with  approximately $10 million in deposits,  represents the
Bank's first banking office outside of Tompkins County.  Odessa,  New York is in
Schuyler County, which is adjacent to Tompkins County.

FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS
     The Company's  primary revenue source is interest income derived from loans
and  securities.  The  Company  offers a broad  range  of  short to  medium-term
business and personal loans and consumer  leases.  Commercial loans include both
collateralized  and  uncollateralized   loans  for  working  capital  (including
inventory  and   receivables),   business   expansion   (including  real  estate
acquisitions  and  improvements),  and  purchases  of equipment  and  machinery.
Consumer loans include  collateralized and uncollateralized  loans for financing
automobiles,  boats, home  improvements,  and personal  investments.  A detailed
analysis of the  Company's  financial  condition  and results of  operations  is
included in the Management  Discussion & Analysis  section of the Company's 1997
Annual Report to Shareholders  (Annual Report),  incorporated by reference under
Item 8, herein.

                                       2


NARRATIVE DESCRIPTION OF BUSINESS
     The Company  conducts  commercial  and  consumer  banking  business,  which
primarily  consists of attracting  deposits from the areas served by its banking
offices and using those deposits to originate a variety of commercial, consumer,
and  real  estate  loans  (including  commercial  loans  collateralized  by real
estate).  The  Company's  principal  expenses  are  interest  paid on  deposits,
interest on  borrowings,  and  operating  and general  administrative  expenses.
Funding sources, other than deposits include:  borrowing,  securities sold under
agreements to repurchase, and cash flow from operations,  lending, and investing
activities.

     The Company conducts trust and investment  management  services through its
Trust and  Investment  Services  Division.  The Trust  and  Investment  Services
Division  provides  a  full  range  of  money  management  services,   including
investment management accounts,  custody accounts, living trusts, life insurance
trusts,  standby trusts,  retirement  plans and rollovers,  will trusts,  estate
settlement, and financial planning.

     As  is  the  case  with  banking  institutions  generally,   the  Company's
operations  are  materially  and  significantly  influenced by general local and
national  economic  conditions and related  monetary and fiscal  policies of the
Federal  government.   Operations  may  also  be  significantly   influenced  by
regulatory  policies  of various  Federal  and State  agencies,  which  regulate
various aspects of the Company's  business.  Deposit flows and cost of funds are
influenced  by returns on  competing  investments  and general  market  rates of
interest.  Lending  activities  are affected by the demand for financing of real
estate and other types of loans,  competing  interest  rates,  and other factors
affecting  local  demand and  availability  of funds.  The Company  faces strong
competition in the attraction of deposits (its primary source of lendable funds)
and in the origination of loans. See "-COMPETITION."

     The Company's primary source of income is interest earned from its loan and
securities  portfolios,   which  is  discussed  more  fully  in  the  Management
Discussion and Analysis section of the Annual Report.

LENDING ACTIVITIES
     A  discussion  of the  Company's  lending  activities  is  included  in the
Management  Discussion and Analysis section of the Annual Report. As of December
31, 1997,  management  is not aware of any  potential  problem  loans,  or loans
classified for regulatory purposes as Substandard, Doubtful, or Loss, which have
not been disclosed as nonperforming assets in the Annual Report.

REAL ESTATE MORTGAGE LOANS
     The  Company  originates  mortgage  loans  to  businesses  to  finance  the
acquisition  and holding of  commercial  real  estate,  and to  individuals  for
residential real estate purchases and financing.  The Company requires  mortgage
title  insurance,  flood  insurance,  and hazard  insurance  in  amounts  deemed
appropriate by management or required by law. Escrow accounts for the payment of
real estate taxes and insurance may also be required.  The Company's real estate
mortgage loans primarily are  underwritten in the Company's  primary market area
on the basis of the value of the underlying real property. The Company carefully
manages  environmental  risks in its real estate loan  portfolio.  Primary risks
associated  with real estate lending  include the borrower's  inability to repay
the debt and a reduction in collateral value.

COMMERCIAL LENDING
     The Company  offers a variety of commercial  loan services  including  term
loans, demand loans, lines of credit,  purchased accounts receivables,  leasing,
and equipment financing. A broad range of short-to-medium term commercial loans,
both collateralized and  uncollateralized,  are made available to businesses for
working  capital  (including  inventory  and  receivables),  business  expansion
(including  acquisitions of real estate and  improvements),  and the purchase of
equipment and machinery.  The purpose of a particular loan generally  determines
its structure.  Commercial loans include loans that support local not-for-profit
corporations.

                                       3


     Commercial  loans typically are underwritten on the basis of the borrower's
repayment  capacity from cash flow and are generally  collateralized by business
assets such as accounts receivable,  equipment, real estate, and inventory. As a
result,  the  availability of funds for the repayment of commercial loans may be
substantially  dependent on the success of the  business  itself.  Further,  the
collateral  underlying the loans may depreciate  over time,  cannot be appraised
with as much  precision as real estate,  and may fluctuate in value based on the
success of the business.  Working capital loans are primarily  collateralized by
short-term assets, while term loans are primarily collateralized by long-term or
fixed assets.  The Company normally requires personal  guarantees for commercial
loans and has  approximately  $8 million of commercial  loans which are fully or
partially guaranteed by the Small Business Administration.

CONSUMER LOANS
     Consumer  loans  made  by  the  Company  include  loans  for   automobiles,
recreation  vehicles,   education,   boats,  mobile  homes,   appliances,   home
improvements  and overdraft  protection.  These loans have been extended through
second mortgages,  personal  (collateralized and uncollateralized) loans, credit
cards, and deposit account collateralized loans.

     Consumer loans are beneficial for the Company because the portfolio risk is
more predictable over time and such loans carry higher interest rates than those
charged on other types of loans.  Consumer loans, however, pose additional risks
of  collectability  when compared to other types of loans,  such as  residential
mortgage  loans.  In many  instances,  the Company  must rely on the  borrower's
ability to repay, since the collateral  normally is of reduced value at the time
of any  liquidation.  Accordingly,  the initial  determination of the borrower's
ability to repay is of primary importance in the underwriting of consumer loans.

     Home equity  lines of credit are extended to  individuals  and secured by a
mortgage covering  residential real estate. The Company requires flood insurance
and hazard insurance in amounts deemed appropriate by management.

LEASE FINANCING
     The Company's lease portfolio is comprised  primarily of leases on vehicles
and equipment for small businesses and individuals. The terms of these loans and
leases  typically  range  from 12 to 180  months and vary based upon the type of
collateral  and amount of the lease.  The current  lease  portfolio is comprised
substantially of direct lease financing of new and used  automobiles.  Marketing
efforts in 1997 have  resulted in growth in the  commercial  leasing  portfolio,
which is expected to continue in 1998.

INVESTMENT ACTIVITIES
     The Company maintains a portfolio of securities such as U.S. government and
agency  securities,  obligations of states and political  subdivisions  thereof,
equity  securities,  and  interest-bearing  deposits.  It is  the  intention  of
management  to  maintain  short  to  intermediate  maturities  in the  Company's
securities portfolio in order to better match the interest rate sensitivities of
its assets and liabilities.

     Investment  decisions are made within policy guidelines  established by the
Company's Board of Directors.  The investment policy established by the Board of
Directors is based on the asset/liability  management goals of the Company.  The
intent of the policy is to  establish a portfolio  of high  quality  diversified
securities,  which  optimize net interest  income  within  acceptable  limits of
safety and liquidity.

                                       4


     Purchases of  securities,  other than  obligations  of states and political
subdivisions  thereof,  are  classified  as  available-for-sale,  though  it  is
generally  management's  intent to hold all  securities to maturity.  Securities
available-for-sale  may be used to  enhance  total  return,  provide  additional
liquidity,   or  reduce   interest   rate   risk.   Securities   classified   as
held-to-maturity   are  comprised  of   obligations   of  states  and  political
subdivisions  thereof.  The Company's current policy is to invest in instruments
with  maturities  between one and fifteen  years.  A desired  maturity  curve is
determined  by the  asset\liability  management  committee  consistent  with the
desired  interest rate  sensitivity.  The accounting  treatment of the Company's
securities  is  addressed in Note 1 of the Notes to the  Consolidated  Financial
Statements of the Annual Report.

     Information  regarding the amortized  cost and fair value of the securities
portfolio  for the years ended 1997 and 1996 is presented in Note 2 of the Notes
to Financial  Statements of the Annual Report. The amortized cost and fair value
of the  securities  portfolio  for the year ended 1995 is  presented  in Table 1
below.

TRUST AND INVESTMENT MANAGEMENT SERVICES
     The Company,  through its Trust and Investment Services Division,  provides
trust and  investment  management  services to residents  of its primary  market
area,  and to those who have relocated  outside of Tompkins  County and retained
their trust relationships with the Company.  Additionally,  the Company provides
financial  planning and alternative  investments  through its relationships with
the INVEST  Financial  Corporation and Fidelity  Investments  Incorporated.  The
Company  also  provides  pension  and 401(k)  benefits  administration  to small
businesses.

     The Trust and  Investment  Services  Division  continues to add services as
part of the Company's  strategy to sharpen  competitive  performance  and expand
markets.  In December  1996, the Trust and  Investment  Services  Division began
providing custodial services for the Company's  securities  portfolio.  In 1997,
The Company formed an alliance with another community bank, in which the Company
began  providing  Trust and Investment  Services  through the newly formed trust
department of the other bank.

DEPOSITS
     Deposit  services  include time deposits,  individual  retirement  accounts
("IRAs"),  checking and other demand  deposit  accounts,  NOW accounts,  savings
accounts, and money market accounts.  Transaction accounts and time deposits are
tailored to the principal market area at rates competitive to those in the area.
All deposit  accounts are insured under the Bank  Insurance  Fund ("BIF") of the
Federal  Deposit  Insurance  Corporation  ("FDIC")  up  to  the  maximum  limits
permitted by law. The Company solicits  deposit accounts from small  businesses,
professional firms,  households,  and educational and governmental  institutions
located  throughout its primary market area.  Total deposits  represented 84% of
total  liabilities on December 31, 1997.  Scheduled  maturities of time deposits
are detailed in Note 6 of the Annual Report.

                                       5



MARKET AREA
     Tompkins County, New York is the Company's primary market area. The Company
has ten full service branch facilities  located in Tompkins County, and one full
service  facility  located in Schuyler  County,  New York,  which is adjacent to
Tompkins County. The Company's deposit gathering,  lending markets and trust and
investment  management services are concentrated in the communities  surrounding
its offices in Ithaca, New York.  Management believes its offices are located in
an area serving  small and  mid-sized  businesses;  and serving low,  middle and
upper income communities.

     Tompkins  County has an  estimated  resident  population  of  approximately
97,000 people,  with approximately  34,000 households,  and an average household
income of approximately $44,000. Education plays a significant role in the local
economy with Cornell  University  and Ithaca  College  being two of the county's
major employers. Unemployment in the county has historically remained well below
the State average, and was 3.1% in December 1997, compared to a State average of
5.7%.  Job growth in the county for the twelve  months ended  December 31, 1997,
totaled 2.98%, compared to total job growth for the State of 1.42%.

MARKET FOR SERVICES
     The Company's  principal  markets are the  established  and expanding small
businesses;  and the low,  moderate,  and high income households within Tompkins
and  surrounding  counties.   Management  believes  its  focus  on  professional
personalized  service,  and the Bank's unique  situation as the only  commercial
bank headquartered in Ithaca, NY, contribute to the Company's competitiveness as
a leading provider of financial services in Tompkins County.

     The Company  continues to invest in  technologies  that allow  customers to
access Bank products and services from anywhere in the country.  This technology
has allowed the Bank to retain  customers  who have moved  outside of the Bank's
principal  market area, and attract  customers for certain products from outside
the Bank's  principal  market area. In 1997, the Trust and  Investment  Services
Division served customers in more than 40 states.  Other products such as credit
cards,  debit cards,  telephone  banking,  and PC banking have greatly  expanded
access to Trust Company  products and services  from outside the Bank's  primary
market area.

COMPETITION
     The Company  encounters  strong  competition  in making  loans,  attracting
deposits,  and  providing  trust  and  investment  services.  Competition  among
financial institutions is based upon interest rates offered on deposit accounts,
interest rates charged on loans,  other credit and service charges,  the quality
and scope of the services rendered, and the convenience of banking facilities.

     The deregulation of the banking industry, the widespread enactment of state
laws that accommodate interstate multi-bank holding companies, and an increasing
level of interstate  banking have created a highly  competitive  environment for
commercial  banking in the Company's primary market area. In one or more aspects
of its business,  the Company  competes  with other  commercial  banks,  savings
institutions,  credit unions,  mortgage bankers and brokers,  finance companies,
mutual funds,  insurance companies,  brokerage and investment banking companies,
and other financial  intermediaries  operating in Tompkins County and elsewhere.
Many of these competitors,  some of which are affiliated with large bank holding
companies,  have  substantially  greater  resources and lending limits;  and may
offer certain services the Company does not currently provide. In addition, many
non-bank  competitors,  such as  credit  unions,  are not  subject  to the  same
extensive  Federal  regulations that govern bank holding companies and Federally
insured banks.

     The Company primarily focuses on providing  personalized  banking and trust
and  investment  services to businesses and  individuals  within the market area
where its banking offices are located.  As the only  independent  community bank
headquartered  in  Ithaca,  NY,  management  believes  the  Company's  community
commitment and personalized service are factors that contribute to the Company's
competitiveness.

                                       6


     Customers  are  solicited  through the  personal  efforts of the  Company's
officers and employees.  Management  believes a locally-based bank can possess a
clearer  understanding  of local  commerce  and the  needs of local  businesses.
Consequently,  management  expects to be able to make prudent lending  decisions
quickly and more equitably  than many of its  competitors  without  compromising
asset quality or the Company's profitability.

     The Company  recognizes  that its employees are the key to providing a high
level of personal  service.  During  1997,  the Company  invested  approximately
$100,000 in formal  education of its employees,  and provides  ongoing  internal
training to ensure  employees are  knowledgeable  of the Company's  products and
services.

     The Company offers state-of-the-art facilities, convenient office locations
and service hours,  an extensive ATM network,  telephone  banking  services,  PC
banking  services,  electronic  bill  payment  services,  and a wide  variety of
financial products.  Management  periodically reviews the scope of the Company's
products and services to assess whether  additional  products or services should
be offered,  giving consideration to customer demand, market opportunities,  and
available resources.

REGULATION

     As a registered bank holding company, the Company is subject to examination
and comprehensive  regulation by the FRB, and the Bank is subject to examination
and  comprehensive  regulation  by the  FDIC  and the  New  York  State  Banking
Department ("NYSBD"). Each of these agencies issues regulations and requires the
filing of reports  describing  the  activities  and  financial  condition of the
entities under its jurisdiction. Likewise, such agencies conduct examinations on
a recurring  basis to evaluate the safety and soundness of the  institution  and
test  compliance  with various  regulatory  requirements  relating to:  Consumer
Protection,  Fair Lending, the Community  Reinvestment Act, sales of non-deposit
investments, electronic data processing, and trust department activities.

     Under FRB regulations,  the Company may not, without providing prior notice
to the FRB,  purchase or redeem its own Common Stock if the gross  consideration
for the purchase or redemption, combined with the net consideration paid for all
such purchases or redemptions  during the preceding  twelve months,  is equal to
ten percent or more of the Company's consolidated net worth.  Additionally,  FRB
policy provides that dividends shall not be paid except out of current  earnings
and  unless  prospective  rate of  earnings  retention  by the  Company  appears
consistent  with  its  capital  needs,  asset  quality,  and  overall  financial
condition.

     The FRB and FDIC have  promulgated  capital  adequacy  guidelines  that are
considered by the agencies in examining  and  supervising a bank or bank holding
company; and in analyzing any applications a bank or holding company may make to
the appropriate agency. In addition,  for supervisory purposes the agencies have
promulgated regulations establishing five categories of capitalization,  ranging
from well capitalized to critically  undercapitalized,  depending upon the level
of  capitalization  and  other  factors.  Currently,  the  Company  and the Bank
maintain  leverage and risk-based  capital ratios above the required  levels and
are considered well capitalized under the FRB and FDIC regulations. A comparison
of the  Company's  capital  ratios and the various  regulatory  requirements  is
included in Note 15 of the Notes to  Consolidated  Financial  Statements  of the
Annual Report.

     Bank deposit  accounts  are insured by the BIF,  generally in amounts up to
$100,000 per  depositor.  The FDIC has the power to  terminate a bank's  insured
status or to temporarily suspend it under special conditions.  Deposit insurance
coverage is maintained  by payment of premiums  assessed to banks insured by the
BIF.

     Based  upon the  capital  strength  of the Bank and a  favorable  FDIC risk
classification,  the Bank is not currently subject to BIF insurance assessments.
Beginning in January 1997, the Bank,  and all BIF insured banks,  are subject to
special assessments to repay Financing Corporation (FICO) bonds, which were used
to repay  depositors of failed  Savings and Loan  Associations  after the former
Federal  Savings  and  Loan  Insurance  Fund  became   insolvent.   The

                                   7


special assessments  attributable to the FICO bonds added approximately  $50,000
to the Company's operating expenses in 1997, compared to 1996.

EMPLOYEES
     At December 31, 1997, the Company employed 235 employees,  approximately 45
of which are  part-time.  No employees  are covered by a  collective  bargaining
agreement and the Company believes its employee relations are excellent.
