                                     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 1956, as amended.  The  principal  offices of the Company and its
wholly-owned  operating  subsidiary,  Tompkins  County Trust Company (the "Trust
Company" or 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.  Unless the context  otherwise  requires,  all
references   herein  to  the  "Company"   include  its  wholly-owned   operating
subsidiary, the Bank.

         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.

         In February 1998,  the Trust Company  formed a subsidiary  corporation,
Tompkins  Real  Estate  Holdings,  Inc.,  which was  formed to qualify as a real
estate  investment trust.  Tompkins Real Estate Holdings,  Inc. became an active
subsidiary of the Trust Company on June 1, 1998.

STOCK SPLIT
         On March 15, 1998, a three-for-two  stock split was paid in the form of
a stock dividend to  shareholders  of record on March 1, 1998. All share and per
share data included herein has been retroactively  adjusted to reflect the stock
split.

STOCK REPURCHASE TRANSACTIONS
      In October 1996, the Company  repurchased 366,556 shares of its own common
stock in a privately  negotiated sale from an unrelated  third party.  The stock
was purchased at a price of $18.33 per share, for a total purchase price of $6.7
million.  In May 1997,  the Company  repurchased  120,000  shares in a privately
negotiated  transaction.  The shares  were  purchased  at $22.53 per share for a
total purchase price of $2.67 million. In December 1998, The Company repurchased
12,207 shares in a privately negotiated  transaction.  The shares were purchased
at $34.00 per share,  for a total purchase price of $415,000.  All of the shares
from the  repurchase  transactions  described  above have been  returned  to the
status of authorized but unissued.

      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.  During 1998, 5,038 shares were repurchased under this
program,  for a total cost of $169,000.  The shares  repurchased during 1998 are
the only  shares that have been  purchased  under this  program,  and all of the
shares  repurchased  under the  program  have  been  returned  to the  status of
authorized but unissued.

                                       2



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 loans,  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 1998
Annual Report to Shareholders  (Annual Report),  incorporated by reference under
Item 7, herein.


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 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, 1998,  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.

                                       3



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.

         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  $8.2 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.

                                       4



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 and 1998 have  resulted  in growth in the  commercial
leasing portfolio, which is expected to continue in 1999.

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.

         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 1998 and 1997 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 1996 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  initiated a "Trust  Alliance"  program,  in which the Company began
providing  servicing  and  administrative  support  to the trust  department  of
another  community  bank. As of March 1999, the Company had Trust Alliances with
two community banks in New York State and one in Pennsylvania.

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 81% of
total  liabilities on December 31, 1998.  Scheduled  maturities of time deposits
are detailed in Note 6 of the Annual Report.

MARKET AREA
         Tompkins  County,  New York is the Company's  primary  market area. The
Company has 13 offices; including, 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 areas  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 2.6% in December 1998, compared to a State average of
5.1%.  Job growth in the county for the twelve  months ended  December 31, 1998,
totaled 0.81%, compared to total job growth for the State of 1.01%.

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 1998, the Trust and  Investment  Services
Division served customers in more than 42 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.

                                       6



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  focuses  primarily 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.

         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 1998, the Company invested approximately
$124,000 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.

                                       7



REGULATION
         As a  registered  bank  holding  company,  the  Company  is  subject to
examination  and  comprehensive  regulation  by the FRB.  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 special
assessment attributable to the FICO bonds was approximately $56,000 in 1998.

EMPLOYEES
         At December 31, 1998, the Company employed 237 employees, approximately
47 of which were part-time.  No employees are covered by a collective bargaining
agreement and the Company believes its employee relations are excellent.
