PART I

ITEM 1. BUSINESS

GENERAL

Community Bank System, Inc. ("Company") was incorporated on April 15, 1983,
under the Delaware General Corporation Law. Its principal office is located at
5790 Widewaters Parkway, DeWitt, New York 13214 and its telephone number is
(315) 445-2282. The Company became a bank holding company in 1984 with the
acquisition of The St. Lawrence National Bank ("St. Lawrence Bank") on February
3, 1984 and the First National Bank of Ovid (renamed Horizon Bank, N.A. or
"Horizon Bank") on March 2, 1984. Also in 1984 the Company obtained a national
bank charter for its third wholly-owned subsidiary bank, The Exchange National
Bank ("Exchange Bank"), and on July 1, 1984 Exchange Bank acquired the deposits
and certain of the assets of three branches of the Bank of New York located in
Southwestern New York. On September 30, 1987, the Company acquired The Nichols
National Bank ("Nichols Bank") located in Nichols, New York. On September 30,
1988, the Company acquired ComuniCorp, Inc., a one-bank holding company located
in Addison, New York, the parent company to Community National Bank ("Community
Bank").

On March 26, 1990, Community Bank opened the Corning Market Street branch from
the Company's acquisition of deposits and certain assets from Key Bank of
Central New York. On January 1, 1992, the Company's five banking affiliates
consolidated into a single, wholly-owned national banking subsidiary, known as
Community Bank, N.A. ("Bank"). On March 31, 1993, the Bank's marketing
representative office in Ottawa, Canada was closed. On June 3, 1994, the Company
acquired three branch offices in Canandaigua, Corning and Wellsville, New York
from the Resolution Trust Corporation. On October 28, 1994, the Company acquired
the Cato, New York branch of The Chase Manhattan Bank, N.A. On July 14, 1995,
the Company acquired 15 branch offices from The Chase Manhattan Bank, N.A.
located in Norwich, Watertown (two), Boonville, New Hartford, Utica,
Skaneateles, Geneva, Pulaski, Seneca Falls, Hammondsport, Canton, Newark (two),
and Penn Yan, New York ("Chase Branches"). On December 15, 1995, the Company
sold three of the former Chase Branches, located in Norwich, New Hartford, and
Utica, to NBT Bank, N.A. On June 16, 1997 the Company acquired eight branches
from Key Bank of New York located in Alfred, Cassadaga, Clymer, Cuba, Gowanda,
Ripley, Sherman, and Wellsville in Southwestern New York State. On July 18, 1997
the Company acquired 12 branches from Fleet Bank located in Old Forge,
Boonville, Ogdensburg, St. Regis Falls, Gateway Plaza, Watertown (2), Clayton,
Lowville, Massena (2), and Gouverneur in Northern and Central New York State.
Five of the former Fleet offices or existing Bank offices in Watertown (2),
Ogdensburg, Gouverneur, and Massena have since been combined.

The Company had a wholly-owned data processing subsidiary, Northeastern Computer
Services, Inc. ("Northeastern"). Northeastern was acquired by the Company from
The St. Lawrence Bank on May 31, 1984 pursuant to a corporate reorganization.
Northeastern had previously been a wholly-owned subsidiary of The St. Lawrence
Bank and was the survivor of a merger with Lawban Computer Systems, Inc.,
another wholly-owned subsidiary of the St. Lawrence Bank. Northeastern's office
was located at 6464 Ridings Road, Syracuse, New York. In December 1991, the
Company entered into a five year agreement with Mellon Bank, N.A. ("Mellon") to
provide data processing services (the agreement has since been renewed with the
subsequent acquiror of Mellon's data services, Fiserv, Inc., for a term ending
December 31, 2002). On June 30, 1992, Northeastern ceased operations. On January
17, 1997 all the outstanding shares of common stock of Northeastern were
transferred from the Company to Community Bank, N.A. On that date, Northeastern
became a wholly-owned subsidiary of the Bank and changed its name to CBNA
Treasury Management Corporation ("CBTM"). CBTM is now utilized by the Bank to
manage its Treasury function, including asset/liability, investment portfolio,
and liquidity management.

The Company also had a wholly-owned mortgage banking subsidiary, Community
Financial Services, Inc. (CFSI), which was established in June 1986; it
commenced operation in January 1987. In July 1988, CFSI purchased Salt City
Mortgage Corp., a Syracuse-based mortgage broker. CFSI was dissolved in 1990.

In July 1996, the Company purchased Benefit Plans Administrators of Utica, New
York, a pension administration and consulting firm serving sponsors of defined
benefit and defined contribution plans.

On February 3, 1997, the Company formed a subsidiary business trust, Community
Capital Trust I, for the purpose of issuing preferred securities which qualify
as Tier 1 capital. Concurrent with its formation, the trust issued $30,000,000
of 9.75% preferred securities in an exempt offering maturing in year 2027 and
guaranteed by the Company. The entire net proceeds to the trust from the
offering were invested in junior subordinated obligations of the Company.

The Company provides banking services through its two regional offices at 45-49
Court Street, Canton, New York and 201 North Union Street, Olean, New York, as
well as through 65 customer facilities in the eighteen counties of St. Lawrence,

1


Jefferson, Lewis, Oneida, Cayuga, Seneca, Ontario, Oswego, Wayne, Yates,
Allegany, Cattaraugus, Tioga, Steuben, Chautauqua, Franklin, Herkimer, and
Onondaga. The administrative office is located at 5790 Widewaters Parkway,
DeWitt, New York, in Onondaga County.

The Bank is a community retail bank committed to the philosophy of serving the
financial needs of customers in local communities. The Bank's branches are
generally located in small towns and villages within its geographic market
areas. The Company believes that the local character of business, knowledge of
the customer and customer needs, and comprehensive retail and small business
products, together with rapid decision-making at the branch and regional level,
enable the Bank to compete effectively. The Bank is a member of the Federal
Reserve System and the Federal Home Loan Bank of New York ("FHLB"), and its
deposits are insured by the FDIC up to applicable limits.

BANKING SERVICES

The Bank offers a range of commercial and retail banking services in each of its
market areas to business, individual, agricultural and government customers.

ACCOUNT SERVICES. The Bank's account services include checking accounts,
negotiable orders of withdrawal ("NOW"), money market accounts, savings
accounts, time deposit accounts, and individual retirement accounts.

LENDING ACTIVITIES. The Bank's lending activities include the making of
residential and farm loans, business lines of credit, working capital
facilities, inventory and dealer floor plans, as well as installment,
commercial, term and student loans.

The Company's predominant focus on the retail borrower enables its loan
portfolio to be highly diversified. About 66% of loans outstanding are oriented
to consumers borrowing on an installment and residential mortgage loan basis. In
addition, the typical loan to the Company's commercial business borrowers is
under $65,000, with only 30% of the commercial portfolio being in loans in
excess of $500,000.

OTHER SERVICES. The Bank offers a range of trust services, including personal
trust, employee benefit trust, investment management, financial planning and
custodial services. In addition, through an affiliation with Prime Vest, Inc.,
the Bank offers nonbank financial products including fixed- and variable-rate
annuities, mutual funds, and stock investments. The Bank also offers safe
deposit boxes, travelers checks, money orders, wire transfers, collections,
foreign exchange, drive-in facilities, automatic teller machines (ATMs), and
twenty-four hour depositories. Through an accounts receivable management
program, the Bank provides a service to qualifying businesses by purchasing
accounts receivable on a discounted basis. Customers of the Bank also receive
pension administration and consulting service pertaining to their defined
benefit and defined contribution plans from CBSI's nonbank subsidiary, Benefit
Plans Administrative Services, Inc. (BPA); BPA also provides services to nonbank
customers.

COMPETITION

The Company, through the Bank, competes in three distinct banking markets in the
Northern ("Northern Market"), Finger Lakes ("Finger Lakes Market"), and Southern
Tier ("Southern Tier Market") regions of New York State. The Bank considers its
primary market areas in these regions to be the counties in which it has banking
facilities. Major competitors in these markets primarily include local branches
of banks based in Boston, Massachusetts, Albany or Buffalo, New York, and
Cleveland, Ohio, as well as local independent banking and thrift institutions
and federal credit unions. Other competitors for deposits and loans within the
Bank's market areas include insurance companies, money market funds, consumer
finance companies and financing affiliates of consumer durable goods
manufacturers. Lastly, personal and corporate trust and investment counseling
services in competition with the Bank are offered by insurance companies,
investment counseling firms and other financial service firms, and individuals.

NORTHERN MARKET. Branches in the Northern Market compete for loans and deposits
in the six county primary market area of St. Lawrence, Jefferson, Lewis,
Franklin, Herkimer, and Oneida Counties in Northern New York State. Within this
market area, the Bank maintains a market share(1) of 29.0% including commercial
banks, credit unions, savings and loan associations and savings banks. The Bank
operates 29 customer facilities in this market and is ranked either first or
second in market share in 17 of the 20 towns where these offices are located.

FINGER LAKES MARKET. In the Finger Lakes Market, the Bank operates 14 customer
facilities competing for loans and deposits in the six-county primary market
area of Seneca, Oswego, Ontario, Wayne, Onondaga, and Cayuga Counties. Within
the Finger Lakes Market area, the Bank maintains a market share(1) of
approximately 2.6% including commercial

2



banks, credit unions, savings and loan associations and savings banks. The Bank
is ranked either first or second in market share in seven of the eleven Finger
Lakes Market area towns where its offices are located.

SOUTHERN TIER MARKET. The Bank's Southern Tier Market consists of two
sub-markets, the Olean submarket and the Corning submarket.

OLEAN SUBMARKET. The Olean Submarket competes for loans and deposits in the
primary market area of Cattaraugus, Chautaugua, and Allegany Counties in the
Southern Tier of New York State. Within this area, the Bank maintains a market
share(1) of approximately 13.7% including commercial banks, credit unions,
savings and loan associations and savings banks. The Olean Submarket operates 14
office locations, and the Bank is ranked either first or second in market share
in all 11 towns where these offices are located.

CORNING SUBMARKET. The Corning Submarket competes for loans and deposits in the
primary market area of Steuben, Yates and Tioga Counties in the Southern Tier of
New York State. Within this area, the Bank maintains a market share(1) of
approximately 10.1% including commercial banks, credit unions, savings and loan
associations and savings banks. The Corning Submarket operates ten office
locations, and the Bank is ranked either first or second in market share in
eight of the nine towns where these offices are located. The Bank also competes
for loans where it has no banking facilities; this secondary market area
includes Chemung and Schuyler Counties in New York State, and Tioga County in
Pennsylvania.

(1) Deposit market share data as of June 30, 1997, as calculated by Sheshunoff
Information Services, Inc. The number of facilities also includes two de novo
offices opened in 1998 for which deposit market share is de minimus.

EMPLOYEES

As of December 31, 1997, the Bank employed 726 full-time equivalent employees
versus 578 at year-end 1996. The Bank provides a variety of employment benefits
and considers its relationship with its employees to be good.

CERTAIN REGULATORY CONSIDERATIONS

Bank holding companies and national banks are regulated by state and federal
law. The following is a summary of certain laws and regulations that govern the
Company and the Bank. To the extent that the following information describes
statutory or regulatory provisions, it is qualified in its entirety by reference
to the actual statutes and regulations thereunder.

BANK HOLDING COMPANY SUPERVISION

The Company is registered as a bank holding company under the Bank Holding
Company Act of 1956, as amended (the "BHCA") and as such is subject to
regulation by the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"). As a bank holding company, the Company's activities and those
of its subsidiary are limited to the business of banking and activities closely
related or incidental to banking. Under Federal Reserve Board policy, a bank
holding company is expected to act as a source of financial strength to its
subsidiary banks and to make capital contributions to a troubled bank
subsidiary. The Federal Reserve Board may charge the bank holding company with
engaging in unsafe and unsound practices for failure to commit resources to a
subsidiary bank when required. A required capital injection may be called for at
a time when the Company does not have the resources to provide it. Any capital
loans by the Company to its subsidiary bank would be subordinate in right of
payment to depositors and to certain other indebtedness of such subsidiary
banks.

The BHCA requires the prior approval of the Federal Reserve Board in any case
where a bank holding company proposes to acquire direct or indirect ownership or
control of more than 5% of any class of the voting shares of, or substantially
all of the assets of, any bank (unless it owns a majority of such bank's voting
shares) or otherwise to control a bank or to merge or consolidate with any other
bank holding company. The BHCA also prohibits a bank holding company, with
certain exceptions, from acquiring more than 5% of the voting shares of any
company that is not a bank.

The Riegal-Neal Interstate Banking and Efficiency Act of 1994 (enacted on
September 29, 1994) provides that, among other things, substantially all state
law barriers to the acquisition of banks by out-of-state bank holding companies
are eliminated effective September 29, 1995. The law also permits interstate
branching by banks effective as of June 1, 1997, subject to the ability of
states to opt-out completely or to set an earlier effective date. The Company
anticipates that the effect of the new law may be to increase competition within
the markets where the Company operates, although the Company cannot predict the
effect to which competition will increase in such markets or the timing of such
increase.


3



OCC SUPERVISION

The Bank is supervised and regularly examined by the OCC. The various laws and
regulations administered by the OCC affect corporate practices such as payment
of dividends, incurring debt, and acquisition of financial institutions and
other companies, and affect business practices, such as payment of interest on
deposits, the charging of interest on loans, types of business conducted and
location of offices. There are no regulatory orders or outstanding issues
resulting from regulatory examinations of the Bank.

LIMITS ON DIVIDENDS AND OTHER REVENUE SOURCES

The Company's ability to pay dividends to its shareholders is largely dependent
on the Bank's ability to pay dividends to the Company. In addition to state law
requirements and the capital requirements discussed below, the circumstances
under which the Bank may pay dividends are limited by federal statutes,
regulations and policies. For example, as a national bank, the Bank must obtain
the approval of the OCC for the payment of dividends if the total of all
dividends declared in any calendar year would exceed the total of the Bank's net
profits, as defined by applicable regulations, for that year, combined with its
retained net profits for the preceding two years. Furthermore, the Bank may not
pay a dividend in an amount greater than its undivided profits then on hand
after deducting its losses and bad debts, as defined by applicable regulations.
At December 31, 1997, the Bank had $21.2 million in undivided profits legally
available for the payment of dividends.

In addition, the Federal Reserve Board and the OCC are authorized to determine
under certain circumstances that the payment of dividends would be an unsafe or
unsound practice and to prohibit payment of such dividends. The payment of
dividends that deplete a bank's capital base could be deemed to constitute such
an unsafe or an unsound practice. The Federal Reserve Board has indicated that
banking organizations should generally pay dividends only out of current
operating earnings.

There are also statutory limits on the transfer of funds to the Company by its
banking subsidiary whether in the form of loans or other extensions of credit,
investments or asset purchases. Such transfers by the Bank to the Company
generally are limited in amount to 10% of the Bank's capital and surplus, or 20%
in the aggregate. Furthermore, such loans and extensions of credit are required
to be collateralized in specified amounts.

CAPITAL REQUIREMENTS

The Federal Reserve Board has established risk-based capital guidelines which
are applicable to bank holding companies. The guidelines established a framework
intended to make regulatory capital requirements more sensitive to differences
in risk profiles among banking organizations and take off-balance sheet
exposures into explicit account in assessing capital adequacy. The Federal
Reserve Board guidelines define the components of capital, categorize assets
into different risk classes and include certain off-balance sheet items in the
calculation of risk-weighted assets. At least half of the total capital must be
comprised of common equity, retained earnings and a limited amount of perpetual
preferred stock, less goodwill ("Tier I capital"). Banking organizations that
are subject to the guidelines are required to maintain a ratio of Tier I capital
to risk-weighted assets of at least 4.00% and a ratio of total capital to
risk-weighted assets of at least 8.00%. The appropriate regulatory authority may
set higher capital requirements when an organization's particular circumstances
warrant. The remainder ("Tier 2 capital") may consist of a limited amount of
subordinated debt, limited-life preferred stock, certain other instruments and a
limited amount of loan and lease loss reserves. The sum of Tier I capital and
Tier 2 capital is "total risk-based capital." The Company's Tier I and total
risk-based capital ratios as of December 31, 1997 were 9.30% and 10.55%,
respectively.

In addition, the Federal Reserve Board has established a minimum leverage ratio
of Tier I capital to quarterly average assets less goodwill ("Tier I leverage
ratio") of 3.00% for bank holding companies that meet certain specified
criteria, including that they have the highest regulatory rating. All other bank
holding companies are required to maintain a Tier I leverage ratio of 3.00% plus
an additional cushion of at least 100 to 200 basis points. The Company's Tier I
leverage ratio as of December 31, 1997 was 5.67%, which exceeded its regulatory
requirement of 4.00%. The guidelines also provide that banking organizations
experiencing internal growth or making acquisitions will be expected to maintain
strong capital positions substantially above the minimum supervisory levels,
without significant reliance on intangible assets. The Company is subject to the
same OCC capital requirements as those that apply to the Bank.

In February 1994, the federal banking agencies proposed amendments to their
respective risk-based capital requirements that would explicitly identify
concentration of credit risk and certain risks arising from nontraditional
activities, and the management of such risks, as important factors to consider
in assessing an institution's overall capital adequacy. The proposed amendments
do not, however, mandate any specific adjustments to the risk-based capital
calculations as a result


4


of such factors. On August 24, 1994, the Federal Reserve Board issued proposed
amendments to its risk-based capital standards that would increase the amount of
capital required under such standards for long-dated interest rate and exchange
rate contracts and for derivative contracts based on equity securities and
indexes, precious metals (other than gold) and other commodities. The proposed
amendments would also permit banking institutions to recognize the effect of
bilateral netting arrangements in calculating their exposure to derivative
contracts for risk-based capital purposes. The Company and the Bank do not
expect that these proposals, if adopted in their current form, would have a
material effect on its financial condition or results of operations.

FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991

In December 1991, Congress enacted the Federal Deposit Insurance Corporation
Improvement Act of 1991 ("FDICIA"), which substantially revised the bank
regulatory and funding provisions of the Federal Deposit Insurance Act and made
significant revisions to several other federal banking statutes. FDICIA provides
for, among other things, (i) a recapitalization of the Bank Insurance Fund (the
"BIF") of the FDIC by increasing the FDIC's borrowing authority and providing
for adjustments in its assessment rates; (ii) annual on-site examinations of
federally-insured depository institutions by banking regulators; (iii) publicly
available annual financial condition and management reports for financial
institutions, including audits by independent accountants; (iv) the
establishment of uniform accounting standards by federal banking agencies; (v)
the establishment of a "prompt corrective action" system of regulatory
supervision and intervention, based on capitalization levels, with more scrutiny
and restrictions placed on depository institutions with lower levels of capital;
(vi) additional grounds for the appointment of a conservator or receiver; (vii)
a requirement that the FDIC use the least-cost method of resolving cases of
troubled institutions in order to keep the costs to insurance funds at a
minimum; (viii) more comprehensive regulation and examination of foreign banks;
(ix) consumer protection provisions including a Truth-in-Savings Act; (x) a
requirement that the FDIC establish a risk-based deposit insurance assessment
system; (xi) restrictions or prohibitions on accepting brokered deposits, except
for institutions which significantly exceed minimum capital requirements; and
(xii) certain additional limits on deposit insurance coverage.

FDICIA requires federal banking agencies to take "prompt corrective action" with
respect to banks that do not meet minimum capital requirements. FDICIA
establishes five capital tiers: "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized," and "critically
undercapitalized." The following table sets forth the minimum capital ratios
that a bank must satisfy in order to be considered "well capitalized" or
"adequately capitalized" under Federal Reserve Board regulations:

Well Capitalized Adequately Capitalized
---------------- ----------------------

Total Risk-Based Capital Ratio 10% 8%
Tier I Risk-Based Capital Ratio 6% 4%
Tier I Leverage Ratio 5% 4%


5




If a bank does not meet all of the minimum capital ratios necessary to be
considered "adequately capitalized," it will be considered "undercapitalized,"
"significantly undercapitalized," or "critically undercapitalized," depending
upon the amount of the shortfall in its capital. As of December 31, 1997, the
Bank's total risk-based capital ratio and Tier I risk-based capital ratio were
10.55% and 9.30%, respectively, and its Tier I leverage ratio as of such date
was 5.67%. Notwithstanding the foregoing, if its principal federal regulator
determines that an "adequately capitalized" institution is in an unsafe or
unsound condition or is engaging in an unsafe or unsound practice, it may
require the institution to submit a corrective action plan; restrict its asset
growth; and prohibit branching, new acquisitions, and new lines of business.
Among other things, an institution's principal federal regulator may deem the
institution to be engaging in an unsafe or unsound practice if it receives a
less than satisfactory rating for asset quality, management, earnings, or
liquidity in its most recent examination.

Possible sanctions for undercapitalized depository institutions include a
prohibition on the payment of dividends and a requirement that an institution
submit a capital restoration plan to its principal federal regulator. The
capital restoration plan of an undercapitalized bank will not be approved unless
the holding company that controls the bank guarantees the bank's performance.
The obligation of a controlling bank holding company to fund a capital
restoration plan is limited to the lesser of five percent (5%) of an
undercapitalized subsidiary's assets or the amount required to meet regulatory
capital requirements. If an undercapitalized depository institution fails to
submit or implement an acceptable capital restoration plan, it can be subjected
to more severe sanctions, including an order to sell sufficient voting stock to
become adequately capitalized. Critically undercapitalized institutions are
subject to the appointment of a receiver or conservator.

In addition, FDICIA requires regulators to impose new noncapital measures of
bank safety, such as loan underwriting standards and minimum earnings levels.
Regulators are also required to perform annual on-site bank examinations, place
limits on real estate lending by banks and tighten auditing requirements.

Many of the provisions of FDICIA will be implemented through the adoption of
regulations by the various federal banking agencies. Although the precise effect
of the legislation on the Company and the Bank therefore cannot be assessed at
this time, the Company does not anticipate that such regulations will materially
affect its operating results, financial condition, or liquidity.

ITEM 2. PROPERTIES

The Company leases its administrative offices at 5790 Widewaters Parkway,
DeWitt, New York. The Bank owns its regional offices in Olean, New York and
Canton, New York. Of the Bank's remaining 65 customer facilities, 42 are owned
by the Bank, and 23 are located on long-term leased premises.

Real property and related banking facilities owned by the Company at December
31, 1997 had a net book value of $15.6 million and none of the properties was
subject to any encumbrances. For the year ended December 31, 1997, rental fees
of $821,000 were paid on facilities leased by the Company for its operations.

The Company has historically paid regular quarterly cash dividends on its common
stock, and declared a cash dividend of $0.20 per share for the first quarter of
1998. The Board of Directors of the Company presently intends to continue the
payment of regular quarterly cash dividends on the common stock, as well as to
make payment of regularly scheduled dividends on the trust preferred stock as
and when due, subject to the Company's need for those funds. However, because
substantially all of the funds available for the payment of dividends by the
Company are derived from the Bank, future dividends will depend upon the
earnings of the Bank, its financial condition, its need for funds and applicable
governmental policies and regulations. See "Supervision and Regulation -- Limits
On Dividends and Other Payments."

ITEM 7. MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULT
OF OPERATIONS

The following discussion is intended to facilitate an understanding and
assessment of significant changes in trends related to the financial condition
of the Company and the results of its operations. The following discussion and
analysis should be read in conjunction with the Selected Consolidated Financial
Data and the Company's Consolidated Financial Statements and related notes
thereto appearing elsewhere in this Prospectus. All references in the discussion
to financial condition and results of operations are to the consolidated
position and results of the Company and its subsidiaries taken as a whole.

NET INCOME AND PROFITABILITY

Net income and diluted earnings per share reached record highs in 1997 at $15.6
million and $2.02, respectively. Compared to 1996, net income rose 10.1% while
earnings per share were up 10.4%. The 1997 return on equity (ROE) increased 21
basis points to 14.09%. All per share results have been adjusted for the
Company's 2 for 1 stock split effective March 12, 1997.

Recurring or core earnings were up 10.2% from last year to $15.3 million after
removing the impact of one-time income and expense items (including $990,000 in
one-time acquisition expense) and net gains/losses on the sale of investment
securities and other assets. 1996's net income climbed 23.2% over the prior year
to $14.1 million while earnings per share were up 7.6% to $1.83; core earnings
rose at a 17% pace.

These results reflect the fourth consecutive year in which acquisitions had an
important impact on the Company's results. Nineteen ninety-seven's earnings
reflected the contributions of eight branches acquired in Southwestern New York
in mid-June from KeyBank, N.A. and twelve branches acquired in Northern New York
in mid July from Fleet Bank. Taken together, these branch locations (of which
three have been consolidated to date) now account for approximately $301 million
in deposits (or 22% of our year-end deposit base) and $95 million in loans (or
11% of our year-end loan base).

1997's improvement in net income over the prior year is explained by the
following major factors:

O Net interest income (full-tax equivalent basis) climbed 13.8% or $7.6
million due to significant increases in earning asset levels. Growth in
loans and investments was $190.7 million (29.2%) and $33.3 million (5.8%),
respectively. Loans grew $100.6 million or 15.4% excluding acquired Key and
Fleet loans. This marks the fifth consecutive year in which loan growth has
exceeded 15%. Earning asset growth was funded by $318 million (31%) in
deposit growth resulting largely from the aforementioned acquisitions and
was partially offset by reduced borrowings. The increase in net interest
income comes despite the net interest margin, at 4.64%, averaging 22 basis
points lower than the 1996 level. The margin decrease is due largely to the
$30 million in 9.75% company-obligated Mandatorily Redeemable Preferred
Securities issued to support the acquisitions. The Company's net interest
margin declined by 25 basis points on average to 4.51% excluding favorable
one-time items.

O Recurring noninterest income was up 30.6% owing to the impact of continued
strength in fiduciary and related services income; significant increases in
BPA/EBT revenue; higher fees from the sale of mutual funds; expanded
revenues from merchant credit and check card processing; the imposition of
ATM surcharge fees; and greater overdraft fees, service charges, and
commissions from an expanded customer base gained from the Key and Fleet
branch purchase.

O Overhead expense increased by 22.3%; excluding one-time costs of the Key
and Fleet acquisitions, growth was $7.4 million or 19.8%. The bulk of the
latter increase reflects costs related to branch expansion, including more
personnel (both acquired branch staff and volume-sensitive positions in
operations and other areas needed to support the expanded balance sheet),
greater data processing requirements, expanded facilities costs, increased
amortization of intangible assets, and other associated expenses.

O For the year, one-time acquisition related expense totaled $990,000. These
expenses were more than offset by one-time income totaling $1.4 million as
a result of accretion adjustments on called bonds, an unexpected gain on
life insurance, a gain on $8.2 million in loans sold in the secondary
market in conjunction with a planned interest rate risk strategy, and a
loan late fee recording adjustment. With the exception of two potential
branch consolidations in 1998, the last major installment of Key- and
Fleet-related acquisition expenses was absorbed during fourth quarter 1997.

10



O Loan loss provision expense rose 55% reflecting higher net charge offs and
the Company's practice to cover them by 125%; charge offs related to
acquired Key and Fleet loans were absorbed by the one-time valuation
allowance established at acquisition date for that purpose. The ratio of
net charge-offs to average loans outstanding rose to .50% versus .29% in
1996, largely due to consumer installment loans, which accounted for more
than 90% of 1997's increase in net charge offs; over 60% of consumer charge
offs was due to indirect automobile loans. Nonperforming loans increased to
$4.2 million, a level $1.3 million or 47% higher than one year ago; about
55% of the increase pertains to consumer installment loans with the balance
largely in commercial loans. As a result of tighter loan underwriting
standards, changes in personnel, and strengthened monitoring and control,
management anticipates improvement in the charge-off trend during 1998.

O The Company's effective tax rate was significantly reduced in 1997 because
of greater tax-exempt income.

The above combination of factors resulted in a level of profitability which may
be compared to that of CBSI's peer bank holding companies; this group is
comprised of 126 companies nationwide having $1 billion to $3 billion in assets
based on data through September 30, 1997 as provided by the Federal Reserve
System. Through year-to-date September, net income per dollar employed, or
return on average assets, was 1.06% in 1997, compared to the peer norm of 1.31%.
Shareholder return on equity, or net income as a percent of average equity, was
14.22% for the same period versus the median for peers of 14.78%.

Underlying these improved levels of profitability on an annual basis is a steady
increase in quarterly performance measures for the four quarters of 1997. The
two acquisitions were immediately accretive to earnings in the third quarter
when earnings per share reached a record high of $.55. Fourth quarter earnings
per share were off $.03 from that pace to $.52 largely due to increases in loan
loss provision and selected overhead costs.

SELECTED PROFITABILITY AND OTHER MEASURES

Return on average assets, return on average equity, dividend payout and equity
to asset ratios for the years indicated are as follows:

1997 1996 1995
---- ---- ----
Percentage of net income to
average total assets 1.04% 1.13% 1.09%

Percentage of net income to
average shareholders equity 14.09% 13.88% 13.85%

Percentage of dividends declared
per common share to net income
per common share 37.30% 37.27% 34.79%

Percentage of average shareholders'
equity to average total assets 7.42% 7.90% 7.61%


CASH-ADJUSTED EARNINGS AND PROFITABILITY

Consistent earnings growth has been achieved despite the increasing noncash
expense of amortizing deposit intangibles created by branch acquisitions. Many
analysts consider that a better measure of the economic value of an acquisition
is the cash earnings it generates, which is determined by adding back to
reported earnings the after-tax expense of amortizing the acquisition premium.

On that basis, CBSI's cash earnings increased 12.6% in 1997 to $17.8 million,
reflecting the half-year impact of the summer's acquisitions, and climbed 27.3%
in 1996 to $15.8 million, representing the full-year impact of the mid-1995
Chase branch purchases. Nineteen ninety-five's cash earnings were $12.4 million.
Return on assets is also significantly higher on a cash basis, being 1.19%,
1.26%, and 1.18% in 1997, 1996, and 1995, respectively.

In contrast to 1997's 10.4% increase in reported earnings per share (EPS) to
$2.02, cash-basis EPS rose 12.2% to $2.30. Last year's reported EPS rose 7.6%
compared to 10.8% on a cash basis of $2.05. As opposed to the $.09 decline in

11




1995's reported results, cash EPS rose $.01 to $1.85. Fourth quarter 1997 cash
EPS is $.36 higher than reported EPS on an annualized basis.

Performance measured by tangible or cash return on equity also showed better
improvement than reported results, reaching 16.09% in 1997, almost regaining the
pre-1995 level prior to the $27.5 million capital issuance which financed the
Chase branch purchase. Tangible return on equity was 15.52% in 1996 and 15.0% in
1995.

NET INTEREST INCOME

Net interest income is the Company's principal source of core operating income
for payment of overhead and possible loan losses. It is the amount that interest
and fees on earning assets (loans and investments) exceeds the cost of funds,
primarily interest paid to the Company's depositors as well as interest on
borrowings from the Federal Home Loan Bank of New York. Net interest margin is
the difference between the gross yield on earning assets and the cost of
interest bearing funds as a percentage of earning assets.

Net interest income (with nontaxable income converted to a full tax-equivalent
basis) totaled $63.3 million in 1997; this represents a $7.6 million or 13.6%
increase from the prior year. The increase was entirely due to higher earning
asset volumes, which had a positive impact on net interest income of $9.9
million, while interest rate changes had a negative impact of $2.3 million. In
contrast, interest rate changes in 1996 had a negative impact of only $196,000
versus higher earning asset volumes having a positive impact of $8.3 million.
Combining these components, 1996's net interest income rose $8.2 million or
17.1% over the prior year to $55.7 million.

With regard to the interest income component of 1997's net interest income,
greater average earning assets of $216 million contributed all but 6% of the
$19.9 million more in gross interest income (up 20.3%). Nearly 68% or $147
million in 1997's average earning asset growth resulted from increased lending
activity in existing markets and the impact of loans initially acquired at the
Key and Fleet branches. The average ratio of loans to earning assets increased
2.5 percentage points this year to 55.0% as a consequence of the aforementioned
loan growth. Higher loan volume accounted for $14.0 million of the increase in
gross interest income; higher average loan yields, which rose 10 basis points to
9.55% this year, added $615,000 to interest income. Through September 30, 1997,
the Company's loan yield was in the favorable 70th peer bank percentile.

The remaining $69 million of earning asset growth is explained by an increase in
investment outstandings; this reflects both the strategic use of leveraging when
favorable buying opportunities existed and the impact of investments purchased
from funds provided by 1997's branch acquisitions. Higher investment volumes
(including money market instruments) contributed $5.1 million of the increase in
gross interest income, while higher investment yields (up 1 basis point to
7.58%) added only $238,000 in 1997. Through September 30, 1997, the Company's
investment yield (excluding money market instruments) was in the very favorable
92nd peer bank percentile.

The total of average deposits and borrowings grew by $230 million in 1997,
primarily attributable to acquired deposits. Of the resulting $12.3 million
increase in total interest expense, over 58% of this additional expense was due
to interest paid on time deposits. During 1997, time deposit rates averaged
5.61%, or 12 basis points higher than in 1996. The mix of time deposits to
average liabilities also increased slightly, reflecting the acquired deposits
having a relatively higher proportion of time deposits. CBSI's $30 million in
9.75% trust preferred securities also caused interest expense to rise,
contributing to the 86 basis point increase in the average borrowing rate.

The cost of the Bank's interest-bearing account base not priced relative to the
treasury yield curve remained stable. The average rate on savings (including
interest checking) and money market accounts increased by only two basis points
during 1997, rising from 2.45% in 1996 to 2.47% this year. The ratio of interest
bearing funds to average earning assets rose slightly in 1997 to 87.6%. Overall,
higher interest bearing outstandings contributed $9.1 million more in interest
expense while higher rates added $3.2 million. Through September 30, 1997, the
Company's average cost of funds rate rose to the less favorable 66th peer bank
percentile, as compared to being in the 43rd percentile through September 30,
1996.

In summary, CBSI's net interest margin declined by 22 basis points in 1997, from
4.86% in 1996 to 4.64% this year:

O The average earning asset yield increased 11 basis points to 8.66% because
of the aforementioned increase in average loan yield and an increased mix
of loans to earning assets, as most types of loans have historically had
higher yields than marketable securities.

12



O The increase in the average earning asset yield compares to an unfavorable
31 basis point increase in the average cost of funds (total interest
expense divided by average earning assets) to 4.01% in 1997. This was due
to the aforementioned increased time deposit rate and mix, and the growing
proportion of longer term borrowings (including the trust preferred
securities).

Despite the decline in the Company's net interest margin, it ranks in the peer
normal 51st percentile through September 30, 1997. While the Company's net
interest margin has historically been well above the norm, the primary objective
in recent years has been to maximize shareholder returns through active
utilization of tangible capital. Thus, as management focuses on growing the
earning asset base of the Company, there has been a downward change in margin
resulting from leverage strategies to take advantage of favorable investment
opportunities; this margin decrease is considered secondary to increasing the
future stream of net interest income.

The following table sets forth certain information concerning average
interest-earning assets and interest-bearing liabilities and the yields and rate
thereon for the three-year period ended December 31, 1997. Interest income and
resultant yield information in the tables are on a fully tax-equivalent basis
using a marginal federal income tax rate of 35%. Averages are computed on daily
average balances for each month in the period divided by the number of days in
the period. Yields and amounts earned include loan fees. Nonaccrual loans have
been included in interest earnings for purposes of these computations.

NONINTEREST INCOME

The Company's sources of noninterest income are recurring fees from core banking
operations (including personal trust income) and revenues from one-time events,
defined as net gains/losses from the sale of investments, loans, and
miscellaneous assets. Additional recurring income results from investment
management, recordkeeping, and consulting services provided by Benefit Plans
Administrative Services, Inc. (BPA) and the Bank's Employee Benefit Trust
Function (EBT).

Total noninterest income increased 33% to $11.8 million from 1996 to 1997. A
quarter of the increase was attributable to the acquired branches, and another
quarter attributable to the full year impact of BPA.

Core banking fees (excluding BPA/EBT and nonrecurring income) were up strongly
for the third consecutive year to approximately $9.6 million in 1997, a 26.2%
improvement following a 25.6% increase in 1996. Included in this year's growth
is approximately $785,000 more in fees due to the impact of the former Key and
Fleet branches.

Recurring noninterest income as a percent of total operating income (net
interest income plus recurring noninterest income) reached 15.3% in 1997, up
meaningfully from 13.6% and 12.1% in 1996 and 1995, respectively. While progress
has been steady, this ratio remains below the norm of 21.0% or the 31st peer
percentile.

In light of management's objective to grow noninterest income toward the peer
median, opportunities to develop new fee-based products are actively pursued,
and the collection of fees for providing quality service is emphasized. In 1997,
these efforts resulted in the institution of an ATM transaction surcharge for
nonbank customers and the launching of cash management products for commercial
businesses. The focus on growth has also continued to drive efforts to increase
fiduciary income, control waived fees, and competitively price deposit service
charges and commission-based services.

As a result of these efforts, in addition to the benefits provided by the Key
and Fleet acquisitions and a full year of BPA operations, fees from core banking
operations improved in several key areas in 1997.

16



o Fees from personal trust services expanded to almost $1.2 million, up 7.7%
in 1997 versus 13.1% in 1996, primarily reflecting a greater level of
annual administrative fees on trust and individual investment management
accounts, offset by a decline in estate fees. Continued focus on business
development, including expanded referral programs, is expected to
strengthen future fiduciary income growth. Total assets under management by
CBNA's trust department (excluding BPA/EBT-related assets) were $149
million as of year-end 1997, up from $144 million and $138 million at
year-end 1996 and 1995, respectively.

o Service charges on deposit accounts and overdraft fees increased to $4.9
million in 1997, a 21.3% growth rate versus 21.4% in 1996. The 1997
increase reflects the impact of fees and commissions from an expanded
customer base gained from the Key and Fleet acquisitions and an emphasis on
ensuring competitive pricing and reducing waived fees. Note that 1996's
increase reflected the full year impact of 1995's Chase branch acquisition.

o Fees earned through the Company's Visa affiliation rose 23.4% in 1997 to
$515,000, attributable mainly to continued growth of the Visa Check Card
product (which more than doubled from 1996 to 1997), with Visa merchant
discount fees remaining essentially flat. The direct margin on merchant
discount fees (net of processing expense) dropped 2.3 percentage points to
29.5% in 1997.

o 1997 is the fourth year in which CBSI has offered annuities, mutual funds,
and other investment products through financial services representatives
(FSR's) located in nine selected geographic markets within the Bank's
branch network. These individuals are registered representatives working
through PrimeVest Financial Services, Inc. of Saint Cloud, Minnesota.
Commission income from this activity in 1997 reached $1.0 million on asset
sales of $26.3 million, up over 28% from $782,000 in 1996 on sales of $24.8
million. A greater emphasis continues to be placed on growing this line of
special investment products as evidenced by two additions to sales staff
during the last half of 1997 and the hiring of a full-time program
administrator in early 1998.

General commissions and miscellaneous income at $1.8 million were up more than
44% in 1997. This increase is attributable to $182,000 more in dividends from
the New York State Bankers Association's insurance subsidiary, an increased
level of Canadian exchange revenue, and the impact of miscellaneous fees
generated by the Key and Fleet branches. Nineteen ninety-seven's nonrecurring
other income was $381,000. This includes a $236,000 gain on life insurance and
gains on the sale of student loans and mortgages sold in the secondary market.

Revenue from record keeping and consulting services provided by BPA (acquired in
July 1996) and investment management services provided by the pre-existing EBT
department totaled $1.8 million in 1997 compared to $1.1 million in 1996, a
60.8% increase as a result of the full year impact of BPA operations and strong
business development efforts. Total assets under management by BPA/EBT more than
doubled in 1997 to $125 million as of year end, up from $52 million and $47
million in 1996 and 1995, respectively.

The following table sets forth selected information by category of noninterest
income for the Company for the years and quarters indicated.

NONINTEREST EXPENSE

Noninterest expense or overhead rose $8.3 million or 22.3% in 1997 to $45.8
million compared to a 13.4% increase in 1996. The bulk of 1997's increase is due
to branch expansion. The Key and Fleet acquisitions caused personnel additions
(both acquired branch staff and volume-sensitive positions in operations and
other areas needed to support the expanded balance sheet), greater data
processing requirements, expanded facilities costs, and other expenses
associated with servicing the expanded customer base. Overhead growth also
reflects the impact of a full year of operating Benefit Plans Administrators
acquired in July 1996. Total one-time Key and Fleet-related acquisition expenses
were approximately $990,000 in 1997, including a loss of $47,000 on sale of a
duplicate branch facility (accounted for as an offset to nonrecurring income).
As a percent of average assets, overhead increased from 2.99% in 1996 to 3.07%
in 1997, representing the peer normal 48th percentile.

For CBSI as a whole, higher personnel expense accounted for over 44% of 1997's
increase in overhead, with personnel costs being up 19.2% versus being 14.8%
higher in 1996. Greater salary, benefit, and payroll tax expense primarily
reflect staffing in the new branches, along with modest annual merit awards for
existing personnel. Total full-time equivalent employees (FTE's) at December 31,
1997 were 726 versus 578 a year earlier.

Nonpersonnel expense rose $4.7 million or 25.6% this year as opposed to a $1.9
million or an 11.9% increase in 1996. One-time Key and Fleet-related acquisition
expenses accounted for $897,000 or 19% of the nonpersonnel increase. Higher
occupancy expense, depreciation on equipment, office supplies, telephone,
courier and armored car expense, postage, business development, and computer
services resulted from the impact of the 20 new branches added in mid 1997.
Total amortization of intangibles increased by $1,058,000 or 38.8% to $3.8
million in 1997 as a result of the branch acquisitions. Various other increases
related to inflation, internal volume growth, the full year impact of BPA,
expenses associated with repossessed assets, a change in reporting commission
expense associated with annuity/mutual fund sales, and the valuation of CBSI
director phantom stock were partially offset by lower FDIC insurance expense
which resulted from the absence of a special one-time assessment in 1996 to
rebuild the Savings Association Insurance Fund (SAIF).

The efficiency ratio is defined as overhead expense divided by recurring
operating income (full tax-equivalent net interest income plus noninterest
income, excluding net securities gains and losses); the lower the ratio, the
more efficient a bank is considered to be. In 1997, the efficiency ratio
increased by 2.9 percentage points to 60.9%, which exceeds the national peer
bank median of 57.3% based on data available as of September 30, 1997. The
increase reflects the impact of one-time Key and Fleet acquisition related
expenses incurred in 1997 combined with a disproportionately smaller increase in
operating income, since most of the acquired deposits funded investments rather
than higher yielding loans. However, this year's ratio is essentially equal to
the 60.8% level of 1995, which was impacted by similar circumstances caused by
the Chase branch acquisition.

Excluding all nonrecurring income, one-time expenses, and the Company's
relatively high level of intangible amortization, the efficiency ratio is 55.8%
based on full year 1997 results. This calculation can be more logically compared
to the 57.3% median for peer banks, which generally experience a much lower
level of intangible amortization and which as a group are not heavily impacted
by one-time acquisition expenses. Nonetheless the Company is striving to reduce
its efficiency ratio by capturing opportunities for greater economies of scale
at its enlarged size, including steady deployment of productivity-enhancing
technology. Management has set an objective to bring this ratio (inclusive of
intangible amortization) downward to 55% within the next three years.

While the Company's expense ratios have generally been favorable, management
maintains a heightened focus on controlling costs and eliminating
inefficiencies. Areas for improvement have been identified through detailed peer
comparisons, a bank-wide program of employee involvement in cost containment,
and targeted use of outside consultants. These combined efforts are intended to
offset pressure from price increases and higher transaction volumes and enable
the Company to more fully benefit from economies of scale as it continues to
grow.

INCOME AND INCOME TAXES

Income before tax in 1997 was $24.4 million, up 2.6% over the prior year's
amount. When pre-tax income is recast as if all tax-exempt revenues were fully
taxable on a federal basis, 1997's results rose by $606,000 or 2.5%.

Largely as a result of the acquisitions, pre-tax earnings were favorably
impacted by $7.6 million greater net interest income (full tax-equivalent basis)
and a $2.9 million climb in noninterest income. These factors were partially
offset by $8.3 million more in overhead expense (also related to the
acquisitions), and $1.6 million more in loan loss provision expense associated
with an increased level of consumer loan charge-offs and the need to maintain
adequate reserves in light of CBSI's strong loan growth.

The Company's combined effective federal and state tax rate dropped a
significant 440 basis points this year to 36.2%. The rate decreased because of
an increasing proportion of tax-exempt investment income; a nonrecurring,
nontaxable gain on life insurance; and the lack of 1996's additional taxes and
interest resulting from an IRS tax audit of the years 1990 to 1993.

CAPITAL

Shareholders' equity ended 1997 at $118.0 million, up over 7.9% from one year
earlier, primarily reflective of the contribution of strong earnings less
dividends paid to shareholders. Excluding the $1.8 million after-tax change in
this year's market value adjustment (MVA) on available-for-sale investment
securities, capital rose 6.3%. Shares outstanding increased by nearly 112,000
during 1997 due to the exercise of stock options.

On January 29, 1997, CBSI placed $30 million of fixed rate capital securities
through Community Capital Trust I, a newly formed Delaware business trust,
controlled by CBSI. The 9.75% Capital Securities, Series A of Community Capital
Trust I were priced at 99.325% of par to yield 9.82%. Cash distributions are
payable semi-annually on January 31 and July 31, and began on July 31, 1997. The
9.75% Capital Securities are rated Investment Grade ("BBB-") by Thomson
BankWatch. The proceeds from the issuance were used to fund the Key and Fleet
branch acquisitions, and to redeem the $4.5 million remaining half of CBSI's
preferred stock issued in mid 1995.


19



The ratio of Tier I capital to assets (or Tier I leverage ratio), the basic
measure for which regulators have established a 5% minimum to be considered
"well capitalized," remains sound at 5.67%. This level compares to 5.88% a year
ago. Despite higher capital produced by this year's strong earnings and the
aforementioned Community Capital Trust I, the decrease in the 1997 Tier I ratio
was a result of increased intangibles attributed to the Key and Fleet branch
acquisitions. The total capital to risk-weighted assets ratio of 10.55% as of
year-end 1997 was well above the 6% minimum requirement for "well capitalized"
banks. The Company is confident that capital levels are being prudently balanced
between regulatory and investor perspectives.

Cash dividends declared on common stock in 1997 of $5.7 million represented an
increase of 12.1% over the prior year. This growth reflects the exercise of
stock options, and a two cent per share increase in the quarterly common stock
dividend in the third quarter of 1997 from $.18 to $.20. Dividends declared on
CBSI's preferred stock in 1997 were $180,000 compared to $405,000 in the prior
year, reflecting the aforementioned redemption of preferred stock.

Raising the Company's expected annualized dividend to $0.80 per common share
represents management's confidence that earnings strength is sustainable and
that capital can be maintained at a satisfactory level. The dividend payout
ratio for the year was approximately 38%, or 37% excluding the preferred
dividend, remaining relatively consistent with the 1996 levels of 39% and 36%,
respectively. The Company's targeted payout range for dividends on common stock
is 30-40%. Its payout ratio has historically been strong relative to peers,
ranging from the 60th-77th percentile from 1993 through 1996. The 1997 peer
payout ratio (including preferred dividend) remained high in the 75th peer
percentile.

Additionally, the typical size loan to the variety of commercial businesses in
the Company's market areas is under $65,000, with only 30% of the commercial
portfolio consisting of loans in excess of $500,000. The portfolio contains no
credit card receivables. The overall yield on the portfolio is in the attractive
75th peer percentile.

Loans outstanding, net of unearned discount, reached a record $843 million as of
year-end 1997, up over $190 million or 29.2% compared to twelve months earlier.
Nearly half of 1997's growth was due the contributions of eight branches
acquired in Southwestern New York in mid June from KeyBank, N.A. and twelve
branches acquired in Northern New York in mid July from Fleet Bank. Taken
together, these branch locations now account for approximately $95 million in
loans (or 11% of our year-end loan base). About 20% of 1997's growth took place
in the markets served by the branches purchased from Chase at mid-year 1995;
outstandings at these branches have risen from $12 million at the July 1995
acquisition date to $101 million at year-end 1997. This marks the fifth
consecutive year in which total loan growth has exceeded 15%; loans in 1996 rose
a strong $92 million or 16.5%.

The "Nature of Lending" table below recasts the Company's loan portfolio into
four major lines of business: consumer mortgages, business lending, consumer
indirect, and consumer direct. Comparing the components of loan growth in 1997
versus 1996, the increase in business lending was slightly more this year at 41%
of $191 million in total loan growth versus 40% of 1996's $92 million increase.
About 37% of 1997's loan growth took place in the consumer direct area compared
to the 19% share in 1996. Consumer indirect loans accounted for 16% of this
year's increase, down from 36% in the prior year. Lastly, the share of this
year's total loan increase from consumer mortgages increased slightly to 6% from
1996's level of 5%. The following discusses the underlying reasons for these
changes by each of the Company's four major lending activities or lines of
business.

The combined total of general purpose business lending, dealer floor plans,
mortgages on commercial property, and farm loans is characterized as the
Company's business lending activity. At $288 million, this segment represents
34% of loans outstanding at year end, having expanded its share by five
percentage points since year-end 1993. This relatively high mix compared to the
Bank's other loan types is largely attributable to borrowing by local commercial
businesses. Outstandings climbed over $77 million or 37% in 1997. Comparative
growth rates were 21% for 1996 and 26% in 1995. This year's growth resulted from
strong business development efforts, the aforementioned contribution of acquired
branches, and the addition of a number of experienced commercial lenders over
the last few years.

More than 86% of the Bank's total number of commercial loans have balances less
than $100,000, which as a group constitutes approximately 34% of commercial loan
outstandings. Commercial loans up to $250,000 comprise 23% of loans outstanding
while loans in the size range of $250,000-$500,000 amount to 13%. Again, loans
with balances greater than $500,000 represent 30% of the portfolio; about 9
percentage points of this segment represents floor plan loans to 25 automobile
dealers.

21



Demand for installment debt indirectly originated through automobile, marine,
and mobile home dealers continued to be very active in 1997 for the fourth
consecutive year. Outstandings ended 1997 nearly 19% or $31 million higher
compared to growth of 24% or $33 million in the prior year. Strength was
evidenced in both CBSI's Northern Region, where this type of lending has been
highly successful for a number of years, and in the Southern Region, where the
commitment to indirect lending was re-energized during 1993 and has continued
with success since then. This portfolio segment, of which 92% relates to
automobile lending (71% used vehicles versus 29% new), constitutes 24% of total
loans outstanding, up from its low of 18% at year-end 1993. No indirect loans
were part of the mid-summer 1997 acquisitions.

The segment of the Company's loan portfolio committed to consumer mortgages
includes both fixed and adjustable rate residential lending. It accounts for
$164 million or 19% of total loans outstanding. The growth during the last two
years ($11.9 million or 7.8% in 1997, and $5.1 million or 3.2% in 1996) is lower
than it would otherwise be due to a program which began in mid 1994 to sell
selected fixed rate originations in the secondary market. The purpose of this
program, which resulted in sales of $1.2 million in its first year, $4.3 million
in 1995, $7.2 million in 1996 and $14.0 million this year, is to develop a
meaningful source of servicing income as well as to provide an additional tool
to manage interest rate risk.

The direct consumer lending activity has increased modestly over the last five
years. 1997 outstandings rose 57.5% or $70 million versus 17.0% or $18 million
in 1996 largely due to loans obtained with the summer acquisitions. This line of
business is comprised of conventional installment loans (including some isolated
installment lending to small businesses), personal loans, student loans (which
are sold once principle amortization begins), and borrowing under variable and
fixed rate home equity lines of credit. The consumer direct segment as a percent
of total loans trended downward from 1993 to 1995. However, it stabilized in
1996 at 19%, rising to 23% in 1997.

Ratio of nonperforming assets to
period-end total loans and other real

The impact of interest not recognized on nonaccrual loans, and interest income
that would have been recorded if the restructured loans had been current in
accordance with their original terms, was immaterial. The Company's policy is to
place a loan on a nonaccrual status and recognize income on a cash basis when it
is more than ninety days past due, except when in the opinion of management it
is well secured and in the process of collection.

PROVISION AND RESERVE FOR LOAN LOSSES

Nonperforming loans, defined as nonaccruing loans plus accruing loans 90 days or
more past due, ended 1997 at $4.2 million. This level is approximately $1.3
million or 47% higher than one year earlier; about 55% of the increase pertains
to consumer installment loans with the balance largely in commercial loans.
Because of strong loan growth, however, the ratio of nonperforming loans to
total loans has risen a relatively small five basis points during the year to
.49%. As of September 30, 1997, when the nonperforming loan ratio stood at .53%,
the Company's asset quality was in the favorable 23rd percentile compared to
peers. The ratio of nonperforming assets (which additionally include troubled
debt restructuring and other real estate) to total loans plus OREO is also
favorable at .60%.

Total delinquencies, defined as loans 30 days or more past due and nonaccruing,
have trended slightly higher as a percent of total loans over the last two
years, generally fluctuating within a range of 1.2% to 1.4% in 1996 versus 1.3%
to 1.7% in 1997; a brief seasonal or event-related spike outside these ranges
occurred during both periods. Though commercial and real estate loan
delinquencies have been relatively flat over the last 12 months, installment
loan delinquencies exhibited an up-trend, averaging 2.29% for the last six
months of 1997 versus 1.66% for the same prior year period.

23



As of year-end 1997, total delinquencies for commercial loans, installment
loans, and real estate mortgages were 1.45%, 2.75%, and 1.00%, respectively.
With the exception of installment loans, these measures compare favorably to
delinquencies of peer bank holding companies as of September 30, 1997 of 2.49%,
2.42%, and 1.92%, respectively. Management views the higher installment loan
delinquencies to be temporary and anticipates that the ratio will improve in
1998 with tighter loan underwriting standards, changes in personnel, and
strengthened monitoring and control. The Bank strives to maintain its total and
component category delinquencies below a 2% internal guideline, and is
comfortable that this objective continues to be realistic.

As of September 30, 1997, when overall delinquencies were at 1.72%, the Company
ranked in the 46th peer percentile. Factors contributing to successful
underwriting, collection, and credit monitoring include selective addition of
experienced lenders over the last several years, loan servicing on a
regionally-based level, collection departments focused on taking prompt
corrective action, and a centralized loan review function which is given
priority attention and has regular Board of Director accountability.

Another measure of the Company's good asset quality is a reasonable net
charge-offs record, which finished the year at $3.7 million or .50% of average
loans. As a result of higher installment loan charge-offs, gross charge-offs
rose 80.9% to $4.4 million, or .59% of average loans outstanding versus .41% in
1996. This year's recoveries rose to an all-time record in dollar amount of
$727,000, while down from 1996 in percentage terms to 29.6% of prior year gross
charge-offs. As of September 30, 1997, the Bank's net charge-off ratio was in
the 70th peer percentile. It should be noted, as with the higher installment
delinquencies, management views the growth in installment loan charge-offs to be
temporary.

A timely charge-off policy and relatively low nonperforming loans have enabled
the Company to carry a reserve for loan losses below peers. As a percent of
total loans, the loss reserve ratio has increased to a 1.47% level for the year
ended 1997. Though the reserve ratio is presently in the 59th peer percentile,
coverage over nonperforming loans as of September 30, 1997 was well above the
norm in the 87th percentile; management believes the year-end level at 298% to
be ample. The Company's small business loan orientation has historically reduced
the likelihood of large, single borrower charge-offs. Another measure of comfort
to management is that after conservative allocation by specific customer and
loan type, over 14% of loan loss reserves remains available for absorbing
general, unforeseen loan losses.

The annual loan loss provision has characteristically been well in excess of net
charge-offs, which have had coverage of over 1.2 times since 1990. This practice
has enabled a steady increase in the loan loss reserve level, which rose by $4.3
million or 53.0% to an all-time high of $12.4 million at year-end 1997 (includes
a $3.5 million valuation allowance to absorb acquired Key and Fleet loan
charge-offs). As a percentage of average loans, the annual loan loss provision
was well above the peer norm in the 77th percentile as of September 30, 1997.
For full year 1997, the loss provision ratio was .60%, having remained in a .34%
to .48% range during the prior three year period. This upward movement reflects
the need to cover 1997's higher net charge-offs by 125% (excluding those
pertaining to acquired Key and Fleet loans) so as to keep pace with record loan
growth and maintain the loss reserve ratio at an adequate level.

FUNDING SOURCES

Typical of most commercial banking institutions today is the need to rely on a
variety of funding sources to support its earning asset base as well as to
achieve targeted growth objectives. There are three primary sources of funding
that comprise CBSI's overall funding matrix, which considers maturity,
stability, and price: deposits of individuals, partnerships and corporations
(IPC deposits); collateralized municipal deposits; and capital market
borrowings.

1997 $1,190 82.1% $163 11.2% $ 97 6.7% $1,450
1996 $ 903 75.6% $124 10.4% $168 14.1% $1,195
1995 $ 921 86.8% $128 12.6% $ 6 0.6% $1,018
1994 $ 583 71.7% $101 12.4% $129 15.9% $ 813



The Company's funding matrix continues to benefit from a high level of IPC
deposits, which reached an all-time high for a fourth quarter average of $1,190
million, up $287 million or 32% from the comparable 1996 period. IPC deposits
are generally considered to be a bank's most attractive source of funding
because of their general stability and relatively low cost, and because they
represent a working customer base with the potential to be cross-sold a variety
of loan, deposit and other financial service-related products.

Strongly impacting the Company's IPC funding source were the Key and Fleet
branch acquisitions which took place in June and July of this year. These
branches account for approximately $260 million or over 90% of the fourth
quarter growth in IPC deposits. Following initial deposit attrition of a modest
3.3% through year-end 1997, steady acclimation of this new customer base within
the Company will help reduce further erosion of this funding source during 1998.

The mix of CBSI's IPC deposits has changed over the last four years. The steady
growth in time deposit share, from 38% of deposits in 1994 to 49% this year,
reflects consumer movement away from immediately available, lower earning
savings and money market accounts.

26



Deposits of local municipalities increased $39 million or 31% during the past
year, with balances for fourth quarter 1997 averaging $163 million versus $124
million for the same quarter in 1996. The Key and Fleet branch acquisitions
contributed $22 and $27 million, respectively, towards the increase. Excluding
the Key and Fleet branches, the Bank experienced a $10 million or 8% decrease in
municipal deposits. Under New York State Municipal Law, the Company is required
to collateralize all local government deposits with marketable securities from
its investment portfolio. Because of this stipulation, management considers this
source of funding to be equivalent to capital market borrowings. As such, CBSI
endeavors to price these deposits at or below alternative capital market
borrowing rates. Utilization of municipal deposits has gradually been decreasing
over the last four years as a percent of total funding sources.

Capital market borrowings are defined as funding sources available on a national
market basis, generally requiring some form of collateralization. Borrowing
sources for the Company include the Federal Home Loan Bank of New York, as well
as access to the national repurchase agreement market through established
relationships with primary market security dealers. Also considered borrowing
(though it serves as Tier I capital) is the $30 million in 9.75%
company-obligated mandatorily redeemable preferred securities issued to support
1997's acquisitions. Capital market borrowings averaged $98 million or 7% of
total funding sources for fourth quarter 1997 compared to $168 million or 14% of
total funding sources for the same period in 1996. The lower level of borrowings
in 1997 is largely due to the net proceeds from the Key and Fleet transaction
being utilized to repay borrowings. As of December 31, 1997, nearly half or $60
million of capital market borrowings (excluding the aforementioned trust
preferred securities) had original terms of one year or more.

The average daily amount of deposits and the average rate paid on each of the
following deposit categories is summarized below for the years indicated.

INVESTMENTS

The primary objective of CBSI's investment portfolio is to prudently provide a
degree of low-risk, quality assets to the balance sheet. This must be
accomplished within the constraints of: (a) absorbing funds when loan demand is
low and infusing funds when demand is high; (b) implementing certain interest
rate risk management strategies which achieve a relatively stable level of net
interest income; (c) providing both the regulatory and operational liquidity
necessary to conduct day-to-day business activities; (d) considering investment
risk-weights as determined by regulatory risk-based capital guidelines; and (e)
generating a favorable return without undue compromise of other requirements.

When choosing an appropriate investment for balance sheet management, the
applied analytical method favored by the Company is total return. While the type
of strategy considered ultimately determines the scope of analysis performed,
management commonly tests the performance of its investment purchases over a one
and three year forward time horizon, under conditions which include interest
rate movements of up or down 300 basis points from current levels. It is through
this methodology that prepayment risk, embedded option risk, and market value
risk can be properly quantified by the Company.

Throughout 1997, the balance sheet of the Company exhibited a structurally asset
sensitive profile, in large part due to the influence of the Key and Fleet
branch deposit acquisitions consummated in mid summer of this year. As a result,
investment strategies pursued were primarily designed to manage this asset
sensitive interest rate risk exposure, with a focus on improving the relative
performance of net interest income in both rising and falling interest rate
environments.

Among the strategies employed by the Company during 1997 were the purchase of
fixed rate U.S callable agency debentures with three to five years of initial
call protection, as well as premium U.S. agency collateralized mortgage
obligations (CMOs). In addition, a number of longer-dated insured municipal
bonds were added to the portfolio because of their favorable risk/reward profile
when compared to other investment alternatives.

Total portfolio growth slowed to 5.8% during the past year as many of the
Company's capital resources were redirected towards funding growth in the loan
portfolio. As such, much of the 1997 portfolio activity was the result of a
reinvestment of funds from mortgage backed security prepayments and callable
bond proceeds. Total portfolio outstandings as of December 31, 1997 were $612
million as compared to $579 million as of year-end 1996.

The composition of the portfolio continues to favor U.S. Governments and U.S.
Agency mortgage-backed obligations, achieving effective use of regulatory
risk-based capital. At December 31, 1997, these two security types (excluding
Federal Home Loan Bank stock and Federal Reserve Bank stock) accounted for 96%
of total portfolio investments versus 97% in the prior year.

The average life of the portfolio, including the exercise of embedded call
options, increased slightly to 3.6 years as of year end. The increase reflects
$87 million in agency bonds called this year, which resulted in $696,000 of bond
discount accretion being taken into income; $221,000 was earned in 1996 on a
$2.8 million called bond. This source of nonrecurring income added 11 basis
points in average yield to the portfolio (excluding money market instruments) to
7.63% compared to 7.57% in 1996, which was higher by 10 basis points due to bond
discount accretion and another favorable nonrecurring item. Through September
30, 1997, the portfolio's reported average yield at 7.64% was in the 92nd
percentile based on the peer median of 6.74%.

Net losses on the sale of securities were $14,000 in 1997 versus gains of
$32,000 in 1996. Gains and losses incurred by the portfolio are the result of
normal investment management activity, which focuses on improving long-term
portfolio earnings and market value performance.

MARKET RISK

Market risk is the risk of loss in a financial instrument arising from adverse
changes in market rates or prices such as interest rates, foreign currency
exchange rates, commodity prices, and equity prices. The Company's primary
market risk exposure is interest rate risk. The ongoing monitoring and
management of this risk is an important component of the Company's
asset/liability management process, which is governed by policies established by
its Board of Directors that are reviewed and approved annually. The Board of
Directors delegates responsibility for carrying out the asset/liability
management policies to the Asset/Liability Committee (ALCO) of the Company. In
this capacity, ALCO develops guidelines and strategies impacting the Company's
asset/liability management activities based upon estimated market risk
sensitivity, policy limits, and the overall level and trend of market interest
rates.

30




INTEREST RATE RISK

At Community Bank, N.A., the fundamental purpose behind interest rate risk
management is to maximize net interest income over both a short-term tactical
and longer-term strategic time horizon. Because the Company does not believe it
is possible to reliably predict future interest rate movements, it has
maintained an appropriate process and set of measurement tools which enable it
to identify and quantify its sources of interest rate risk.

The primary tool used by the Company in managing interest rate risk is income
simulation. The analysis begins by measuring the impact of differences in
maturity and repricing of all balance sheet positions. Such work is further
augmented by adjusting for prepayment and embedded option risk found naturally
in certain asset and liability classes. Finally, balance sheet growth and
funding expectations are added to the analysis in order to reflect the strategic
initiatives set forth by the Company.

Changes in net interest income are reviewed after subjecting the balance sheet
to an array of treasury yield curve possibilities including the traditional
regulatory requirement of an immediate up or down shock of 200 basis points from
current levels. While such an aggressive movement in rates provides management
with good insight as to how its profit margins may perform under extreme market
conditions, results from a more modest shift in interest rates are used as a
basis to conduct day-to-day business decisions.

The following reflects the Company's one year net interest income sensitivity
analysis as of December 31, 1997 assuming a step up or down in rates over a
twelve-month period (one of the simulation tests used for day-to-day decision
making). In addition, this test assumes a static, no growth balance sheet:

Rate Change Estimated
Basis Points Net Interest Income Sensitivity
------------ -------------------------------
+ 200 1.4%

- 200 -5.0%

The preceding sensitivity analysis does not represent a Company forecast and
should not be relied upon as being indicative of expected operating results.
These hypothetical estimates are based upon numerous assumptions including: the
nature and timing of interest rate levels including yield curve shape,
prepayments on loans and securities, deposit decay rates, pricing decisions on
loans and deposits, reinvestment/replacement of asset and liability cashflows,
and others. While the assumptions are developed based upon current economic and
local market conditions, the Company cannot make any assurances as to the
predictive nature of these assumptions including how customer preferences or
competitor influences might change.

Also, as market conditions vary from those assumed in the sensitivity analysis,
actual results will also differ due to: prepayment/refinancing levels likely
deviating from those assumed, the varying impact of interest rate changes on
caps and floors of adjustable rate assets, the potential effect of changing debt
service levels on customers with adjustable rate loans, depositor early
withdrawals and product preference changes, and other internal/external
variables. Furthermore, the sensitivity analysis does not reflect actions that
ALCO might take in responding to or anticipating changes in interest rates.

LIQUIDITY

Due to the potential for unexpected fluctuations in deposits and loans, active
management of the Company's liquidity is critical. In order to respond to these
circumstances, adequate sources of both on- and off-balance-sheet funding are in
place.

CBSI's primary approach to measuring liquidity is known as the Basic
Surplus/Deficit model. It is used to calculate liquidity over two time periods:
first, the relationship within 30 days between liquid assets and short-term
liabilities which are vulnerable to nonreplacement; and second, a projection of
subsequent cash flow funding needs over an additional 60 days. The minimum
policy level of liquidity under the Basic Surplus/Deficit approach is 7.5% of
total assets for both the 30 and 90 day time horizons. As of year-end 1997, this
ratio was 13.9% and 12.6%, respectively.

EFFECTS OF INFLATION

The financial statements and related data presented herein have been prepared in
accordance with generally accepted accounting principals which require the
measurement of financial position and operating results in terms of historical
dollars without considering changes in the relative purchasing power of money
over time due to inflation.

Virtually all of the assets and liabilities of the Company are monetary in
nature. As a result, interest rate changes have a more significant impact on the
Company's performance than the effects of general levels of inflation.

YEAR 2000

Our Company is keenly aware of the challenges presented by Year 2000 Business
Risk compliance. We have established a task force comprised of key personnel to
define and coordinate the Year 2000 effort. CBSI has adopted the five elements
outlined by its banking regulators: Awareness, Assessment, Renovation,
Validation, and Implementation. It is anticipated that complete review and
verification of our internal systems, as well as those of our major service
providers, will be accomplished by December 31, 1998.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS No.
130, "Reporting Comprehensive Income." This Statement will require the Company
to report comprehensive income in its financial statements issued after December
31, 1997. For the Company, comprehensive income is determined by adding
unrealized investment holding gains or losses during the period to net income.

Also in June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." This Statement requires companies to
disclose financial and descriptive information about its reportable business
segments. Management believes the Company only operates in one segment, which is
the banking segment. Therefore, disclosures required under this pronouncement
will not affect the financial statements of the Company.

The following consolidated financial statements and auditor's reports of
Community Bank System, Inc. and subsidiaries are contained on pages 34 through
54 of this item.

COMMUNITY BANK SYSTEM, INC. AND SUBSIDIARIES

NOTE A: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS
Community Bank System, Inc. (the Company) is a one bank holding company which
wholly owns two active operating subsidiaries, Community Bank, N.A. (the Bank)
and Benefit Plans Administrative Services, Inc. (BPA). In addition, the Company
wholly owns a subsidiary trust and one inactive subsidiary. The Bank operates 67
customer facilities throughout Northern New York, the Finger Lakes Region, the
Southern Tier, and Southwestern New York. It provides individual, business,
agricultural, and government customers with a complete range of banking
services, including qualified retirement plan administration, investment
management, and personal trust services; retail and commercial loan and deposit
products, and nondeposit annuities and investment products. BPA, located in
Utica, New York, provides pension administration and actuarial services to
various customers throughout New York State. The Bank wholly owns one nonbanking
subsidiary, CBNA Treasury Management Corporation (TMC). TMC operates the cash
management, investment, and treasury functions of the Bank. During 1997, the
Company formed a subsidiary business trust, Community Capital Trust I, for the
purpose of issuing manditorily redeemable convertible securities, which are
considered Tier I capital under regulatory capital adequacy requirements. (see
Note Q).

PRINCIPLES OF CONSOLIDATION
The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries: the Bank and its subsidiary TMC; BPA, and a
currently inactive nonbanking subsidiary. All intercompany accounts and
transactions have been eliminated in consolidation.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
The preparation of financial statements in conformity with generally accepted
accounting principles 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 those estimates.

CASH AND CASH EQUIVALENTS
For purposes of reporting cash flows, cash and cash equivalents include cash on
hand, amounts due from banks and federal funds sold. Generally, federal funds
are sold for one-day periods. The carrying amounts reported in the balance sheet
for cash and cash equivalents approximate those assets' fair values.

INVESTMENT SECURITIES
The Company has classified its investments in debt and equity securities as
held-to-maturity or available-for-sale. Held-to-maturity securities are those
for which the Company has the positive intent and ability to hold to maturity,
and are reported at cost, which is adjusted for amortization of premiums and
accretion of discounts. Debt securities not classified as held-to-maturity are
classified as available-for-sale and are reported at fair market value with net
unrealized gains and losses reflected as a separate component of shareholders'
equity, net of applicable income taxes. None of the Company's investment
securities has been classified as trading securities.

The average cost method is used in determining the realized gains and losses on
sales of investment securities, which are reported under other income as
investment security gains (losses). Premiums and discounts on securities are
amortized and accreted, respectively, on a systematic basis over the period to
maturity, estimated life, or earliest call date of the related security.

Fair values for investment securities are based on quoted market prices, where
available. If quoted market prices are not available, fair values are based on
quoted market prices of comparable instruments.

LOANS
Loans are stated at unpaid principal balances. Fair values for variable rate
loans that reprice frequently, with no significant credit risk, are based on
carrying values. Fair values for fixed rate loans are estimated using discounted
cash flows and interest rates currently being offered for loans with similar
terms to borrowers of similar credit quality. The carrying amount of accrued
interest approximates its fair value.

INTEREST ON LOANS AND RESERVE FOR POSSIBLE LOAN LOSSES
Interest on commercial loans and mortgages is accrued and credited to operations
based upon the principal amount outstanding. Unearned discount on installment
loans is recognized as income over the term of the loan, principally by the


38




actuarial method. Nonrefundable loan fees and related direct costs are deferred
and amortized over the life of the loan as an adjustment to loan yield using the
effective interest method.

The Bank places a loan on nonaccrual status and recognizes income on a cash
basis when it is more than ninety days past due (or sooner, if management
concludes collection of interest is doubtful), except when, in the opinion of
management, it is well-collateralized and in the process of collection.

The reserve for possible loan losses is maintained at a level considered
adequate to provide for potential loan losses. The reserve is increased by
provisions charged to expense and reduced by net charge-offs. The level of the
reserve is based on management's evaluation of potential losses in the loan
portfolio, as well as prevailing economic conditions. A loan is considered
impaired, based current information and events, if it is probable that the Bank
will not be able to collect the scheduled payments of principal or interest when
due according to the contractual terms of the loan agreement. The measurement of
impaired loans is generally based on the present value of expected future cash
flows discounted at the historical effective interest rate, except that all
collateral-dependent loans are measured for impairment based on the fair value
of the collateral.

PREMISES AND EQUIPMENT

Premises and equipment are stated at cost less accumulated depreciation. The
annual provision for depreciation is computed using the straight-line method in
amounts sufficient to recognize the cost of depreciable assets over their
estimated useful lives. Maintenance and repairs are charged to expense as
incurred.

OTHER REAL ESTATE

Properties acquired through foreclosure, or by deed in lieu of foreclosure, are
carried at the lower of the unpaid loan balance plus settlement costs, or fair
value less estimated costs of disposal, At December 31, 1997 and 1996, other
real estate, included in other assets, amounted to $881,456 and $745,504,
respectively.

INTANGIBLE ASSETS

Intangible assets represent core deposit value and goodwill arising from
acquisitions. The Company periodically reviews the carrying value of intangible
assets using fair value methodologies. Core deposit intangibles are being
amortized principally on an accelerated basis over ten years. Goodwill is being
amortized on a straight-line basis over 15 to 25 years.

DEPOSITS

The fair values disclosed for demand and savings deposits are equal to the
carrying amounts at the reporting date. The carrying amounts for variable rate
money market accounts and certificates of deposit approximate their fair values
at the reporting date. Fair values for fixed rate certificates of deposit are
estimated using discounted cash flows and interest rates currently being offered
on similar certificates. The carrying value of accrued interest approximates
fair value.

BORROWINGS

The carrying amounts of federal funds purchased and borrowings approximate their
fair values.

INCOME TAXES

Provisions for income taxes are based on taxes currently payable or refundable,
and deferred taxes are based on temporary differences between the tax basis of
assets and liabilities and their reported amounts in the financial statements.
Deferred tax assets and liabilities are reported in the financial statements at
currently enacted income tax rates applicable to the period in which the
deferred tax assets and liabilities are expected to be realized or settled.

EARNINGS PER SHARE AND STOCK SPLIT

As of December 31, 1997 the Company adopted Statement of Financial Accounting
Standards No. 128, "Earnings Per Share." Under this new standard, both basic and
diluted earnings per share are presented for each period for which an income
statement is presented. Basic earnings per share is computed on the basis of
actual weighted average common shares outstanding for the period. Diluted
earnings per share reflects the dilutive effect of outstanding common stock
equivalents.

On March 12, 1997, a two-for-one split of the Company's common stock was
effected in the form of a stock dividend of one share of common stock for each
share of common stock outstanding at the close of business on February 10, 1997.
The number of authorized shares of common stock was increased from 5,000,000 to
20,000,000 pursuant to shareholder approval. All share and per share data of
prior periods has been restated, where required, to retroactively reflect the
stock split.


39




During 1997, the par value of the Company's common stock was changed from $1.25
par to no par $1.00 stated value per share.

FAIR VALUES OF FINANCIAL INSTRUMENTS

The Company determines fair values based on quoted market values where available
or on estimates using present values or other valuation techniques. Those
techniques are significantly affected by the assumptions used, including the
discount rate and estimates of future cash flows. In that regard, the derived
fair value estimates cannot be substantiated by comparison to independent
markets and, in many cases, could not be realized in immediate settlement of the
instrument. Statement Financial Accounting Standard No. 107, "Disclosures about
Fair Value of Financial Instruments," excludes certain financial instruments and
all nonfinancial instruments from its disclosure requirements. Accordingly, the
aggregate fair value amounts presented do not represent the underlying value of
the Company. The fair values of investment securities, loans, and deposits have
been disclosed in footnotes C, D, and G, respectively.

NOTE B: BRANCH ACQUISITIONS

During 1997, the Company acquired certain assets and assumed certain liabilities
relating to eight branch offices of Key Bank, N.A. located in Southwestern New
York State and 12 branch offices of Fleet Bank located in Northern and Central
New York State.

In July 1995, the Company acquired certain assets and assumed certain
liabilities relating to fifteen branch offices of The Chase Manhattan Bank, N.A.
located in the Northern, Central, and Finger Lakes Regions of New York State. In
December 1995, the Company sold the assets and liabilities of three of these
branches to another banking entity. A summary of these acquisitions and the
divestiture activity is as follows:

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



Net core deposit value and goodwill arising from these transactions is being
amortized over ten years on an accelerated basis, and over a range of 15 to 25
years on a straight-line basis, respectively.

The transactions above have been recorded under the purchase method of
accounting and, accordingly, the operating results of the branches acquired have
been included in the Company's consolidated financial statements from the date
of acquisition. Results of operations on a pro forma basis are not presented
since historical financial information for the branches acquired is not
available.

In July 1996, the Company acquired all of the outstanding shares of common stock
of Benefit Plan Administrators, Inc., a pension administration and actuarial
firm, in exchange for 81,250 shares of the Company's common stock. The
transaction was accounted for as a pooling of interests, and, accordingly, the
consolidated financial statements for 1996 include the accounts of Benefit Plan
Administrators. Consolidated financial statements for the prior periods
presented were not restated as the effect on those periods is not significant.

NOTE J: LIMITS ON DIVIDENDS AND OTHER REVENUE SOURCES

The Company's ability to pay dividends to its shareholders is largely dependent
on the Bank's ability to pay dividends to the Company. In addition to state law
requirements and the capital requirements discussed below, the circumstances
under which the Bank may pay dividends are limited by federal statutes,
regulations, and policies. For example, as a national bank, the Bank must obtain
the approval of the Office of the Comptroller of the Currency (OCC) for payment
of dividends if the total of all dividends declared in any calendar year would
exceed the total of the Bank's net profits as defined by applicable regulations,
for that year, combined with its retained net profits for the preceding two
years. Furthermore, the Bank may not pay a dividend in an amount greater than
its undivided profits then on hand after deducting its losses and bad debts, as
defined by applicable regulations. At December 31, 1997, the Bank had
approximately $21,186,000 in undivided profits legally available for the payment
of dividends.

In addition, the Federal Reserve Board and the OCC are authorized to determine
under certain circumstances that the payment of dividends would be an unsafe or
unsound practice and to prohibit payment of such dividends. The payment of
dividends that deplete a bank's capital base could be deemed to constitute such
an unsafe or an unsound practice. The Federal Reserve Board has indicated that
banking organizations could generally pay dividends only out of current
operating earnings. There are also statutory limits on the transfer of funds to
the Company by its banking subsidiary whether in the form of loans or other
extensions of credit, investments, or asset purchases. Such transfers by the
Bank to the Company generally are limited in amount to 10% of the Bank's capital
and surplus, or 20% in the aggregate. Furthermore, such loans and extensions of
credit are required to be collateralized in specific amounts.

NOTE K: BENEFIT PLANS

The Company has a noncontributory pension plan for all eligible employees which
is administered by the Trust Department of Community Bank, N.A. under the
direction of an appointed retirement board. The policy of the Company is to fund
the plan to the extent of its maximum tax deductibility.

The net periodic pension cost and actuarial assumptions for the years ended

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



The decrease in the discount rate from 7.25% to 7% increased the projected
benefit obligation at December 31, 1997 by $306,534.

Plan assets consist primarily of listed stocks, governmental securities, and
cash equivalents. The plan is authorized to invest up to 10% of the fair value
of its total assets in common stock of Community Bank System, Inc. At December
31, 1997 and 1996, the plan holds 41,128 and 52,128 shares, respectively, of the
sponsor company common stock.

The Company also has an Employee Savings and Retirement Plan, which is
administered by the Trust Department of Community Bank, N.A. The Employee
Savings and Retirement Plan includes Section 401(k) and Thrift provisions as
defined under the Internal Revenue Code. The provisions permit employees to
contribute up to 15% of their total compensation on a pre-tax or post-tax basis.
The Company matches 50% of the first 6% of employee contributions. Company
contributions to the trust amounted to $757,444, $598,998, and $522,680 in 1997,
1996, and 1995, respectively.


45




The Company has deferred compensation agreements with its President and Chief
Executive Officer and several former executives and officers whereby monthly
payments are to be provided upon retirement over periods ranging from ten to 25
years. Expense recognized during 1997, 1996 and 1995 related to these agreements
amounted to approximately $257,000, $377,000, and $369,000, respectively.

Effective January 1, 1996, the Board approved a Stock Balance Plan for
nonemployee directors who have completed six months of service. The Plan is a
nonqualified, noncontributory deferred compensation plan. The Plan provides
benefits for periods of service prior to January 1, 1996 based on a
predetermined formula. Amounts credited to participant accounts for all
creditable service after January 1, 1996 are based on performance of the
Company's stock. Participants become fully vested after six years of service.
Benefits are payable in the form of an annuity on the first of the month
following the later of a participant's disassociation from the Board or
attainment of age 70. Unrecognized prior service cost of $628,206 is being
amortized over 20 years. Expense related to the Plan recognized in 1997 and 1996
approximated $203,000, and $150,000, respectively.

NOTE L: POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company provides health and life insurance benefits for eligible retired
employees and their dependents. An employee becomes eligible for these benefits
by satisfying plan provisions which include certain age and/or service
requirements. Medical benefits are based on years of service at retirement, with
forty years of service being required in order to be fully eligible for
benefits. The medical plans pay a stated percentage of medical expenses reduced
by deductibles and other coverages. The Medicare supplement policy provides for
a $100,000 maximum lifetime benefit. Generally, life insurance benefits are
equal to $5,000.

The cost of postretirement benefits is recognized over the active service lives
of employees. The Company is amortizing the transition obligation over a 20-year
period. Net periodic postretirement benefit cost for the years ended December 31
include the following components:

1997 1996 1995
- --------------------------------------------------------------------------------
Service Cost $125,779 $111,252 $80,600

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

46





A 9.5% annual rate of increase in the per capita costs of covered health care
benefits was assumed for 1997, gradually decreasing to 5.5 percent by the year
2017. Increasing the assumed health care cost trend rates by one percentage
point each year would increase the accumulated postretirement benefit obligation
as of January 1, 1997 by $172,500 and increase the aggregate service cost and
interest components of net periodic postretirement benefit cost for 1997 by
$12,000. Discount rates of 7.25% for 1997 and 1996 were used to determine the
accumulated postretirement benefit obligation. The following sets forth the
funded status of the plan as of December 31:



- -----------------------------------------------------------------------------------------------------------------------

The Company granted 8,000 discounted options in 1996 and recognized compensation
expense of approximately $13,000. Restricted stock awarded in 1997 and 1996
amounted to 5,700 and 1,500 shares, respectively. Total expense is based on the
market value of the stock at the date of grant and is being accrued over the
period the restrictions lapse. Expense in 1997, 1996, and 1995 was $145,753,
$92,047, and $77,618, respectively. There were 356,600, 362,300; and 205,500

has established an account for each participating director and credits to such
account the number of shares of Company common stock which would have been
purchased with the director fees and shares equal to the amount of dividends
which would have been received. On the distribution date, the director shall be
entitled to receive either shares of the Company common stock equal to the
number of shares accumulated or at the Company's election, cash equal to the
fair value of the number of shares accumulated. There were 11,920 shares
credited to participant accounts at December 31, 1997 for which a liability of
approximately $373,000 was accrued and approximately $194,000 was recognized as
expense in 1997.

The FASB issued Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation," effective for 1996, which establishes a
fair-value-based method of accounting for stock compensation plans with
employees and others. Alternatively, the statement allows that entities may
continue to account for stock-based compensation plans in accordance with
Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued
to Employees," with disclosure of pro forma amounts reflecting the difference
between cost charged to operations pursuant to APB No. 25 and compensation cost
that would have been charged to operations had Statement No. 123 been applied.
The Company has elected to continue following APB No. 25 in accounting for its
stock-based compensation plans. Application of the fair-value-based accounting
provision of Statement No. 123 results in the following pro forma amounts of net
income and earnings per share:

- --------------------------------------------------------------------------------
1997 1996
- --------------------------------------------------------------------------------
Net Income:
As reported $15,561,506 $14,133,044
Pro forma 15,372,474 13,699,412
Earnings per share:
As reported $2.05 $1.85
Pro forma basic earnings per share 2.03 1.79

The fair value for these options was estimated at the date of grant using a
Black-Scholes options pricing model with the following weighted average
assumptions for 1997 and 1996: risk-free interest rates by grant ranging from
5.48% to 7.83% during 1997 and 5.75% during 1996; dividend yields of 3.00%
during 1997 and 3.95% during 1996; volatility factors of the expected market
price of the Company's common stock of 45.93% for 1997 and 48.21% for 1996; and
a weighted-average expected life of the option of 7.18 years for 1997 and 7.13
years for 1996.

For the purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. Therefore,
these results are not likely to be representative of the effects on reported net
income for future years due to additional years of vesting. At December 31, 1997
the weighted average information for outstanding and exersisable shares is as
follows:




- ------------------------------------------------------------------------------------------------------------------------------

NOTE N: EARNINGS PER SHARE

Basic earnings per share is computed based on the weighted average shares
outstanding. Diluted earnings per share is computed based on the weighted
average shares outstanding adjusted for the dilutive effect of the assumed
exercise of stock options during the year. The following is a reconciliation of
basic to diluted earnings per share for the years ended December 31:

NOTE O: COMMITMENTS, CONTINGENT LIABILITIES AND RESTRICTIONS

The Company is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers.
These financial instruments consist primarily of commitments to extend credit,
which involve, to varying degrees, elements of credit risk in excess of the
amount recognized in the statement of condition. The contract amount of those
commitments to extend credit reflects the extent of involvement the Company has
in this particular class of financial instrument. The Company's exposure to
credit loss in the event of nonperformance by the other party to the financial
instrument for commitments to extend credit is represented by the contractual
amount of the instrument. The Company uses the same credit policies in making
commitments as it does for on-balance-sheet instruments.




- ----------------------------------------------------------------------------------------------------
1997 1996
- ----------------------------------------------------------------------------------------------------

Financial instruments whose contract amounts represent
credit risk at December 31:
Letters of Credit
$2,427,000 $843,000
Commitments to make or purchase loans or
to extend credit on lines of credit 157,931,000 94,730,000
Total $160,358,000 $95,573,000
====================================================================================================


The fair value of these financial instruments is not significant.

49





Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Commitments
generally have fixed expiration dates or other termination clauses and may
require payment of a fee. Since some of the commitments are expected to expire
without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. The Company evaluates each customer's
creditworthiness on a case-by-case basis. The amount of collateral obtained, if
deemed necessary by the Company upon extension of credit, is based on
management's credit evaluation of the customer. Collateral held varies but may
include residential real estate, income-producing commercial properties, and
personal property. The Company has unused lines of credit totaling $43,486,000
and $0 at December 31, 1997 and 1996, respectively. The Company has additional
unused borrowing capacity through collateralized transactions with the Federal
Home Loan Bank.

The Company is required to maintain a reserve balance, as established by the
Federal Reserve Bank of New York. The required average total reserve for the
14-day maintenance period ended December 31, 1997 was $20,688,000 of which
$2,000,000 was required to be on deposit with the Federal Reserve Bank of New
York. The remaining $18,688,000 was represented by cash on hand.

NOTE P: LEASES

Rental expense included in operating expenses amounted to $913,306, $740,398,
and $630,459 in 1997, 1996, and 1995, respectively.

The future minimum rental commitments as of December 31, 1997 for all
noncancelable operating leases are as follows:

Thereafter 3,656,305 0 3,656,305
===============================================================================


NOTE Q: REGULATORY MATTERS

The Bank is 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
Bank's financial statements. Under capital adequacy guideline and the regulatory
framework for prompt corrective action, the Bank must meet specific capital
guidelines that involve quantitative measures of the Bank's assets, liabilities,
and certain off-balance sheet items as calculated under regulatory accounting
practices. The Bank's capital amounts and classification 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 Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as defined in the regulations) to
risk-weighted assets (as defined), and of Tier I capital (as defined) to average
assets (as defined). Management believes, as of December 31, 1997 and 1996, that
the Bank meets all capital adequacy requirements to which it is subject and is
"well capitalized" under the regulatory framework of prompt corrective action.
To be categorized as "well capitalized," the Bank must maintain minimum total
risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the
following table.

Community Bank System, Inc.

We have audited the accompanying consolidated statements of condition of
Community Bank System, Inc. and Subsidiaries as of December 31, 1997 and 1996
and the related consolidated statements of income, changes in shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial condition of Community Bank
System, Inc. and Subsidiaries as of December 31, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997 in conformity with generally
accepted accounting principles.
