COMMUNITY BANK SYSTEM, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (UNAUDITED)

                               SEPTEMBER 30, 1998

NOTE A -- BASIS OF PRESENTATION

     The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with instructions to Form 10-Q and Rule 10-01
of Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for fair presentation have
been included. Operating results for the nine month period ended September 30,
1998 are not necessarily indicative of the results that may be expected for the
year ended December 31, 1998.

     On January 29, 1997, Community Bank System, Inc. formed a wholly-owned
subsidiary, Community Capital Trust I, a Delaware statutory business trust. The
Trust has issued $30 million aggregate liquidation amount of 9.75%
company-obligated Mandatorily Redeemable Preferred Securities representing
undivided beneficial interests in the assets of the Trust. The Company borrowed
the proceeds of the Preferred Securities from the Trust by issuing Junior
Subordinated Debentures to the Trust having substantially similar terms as the
Preferred Securities. The sole assets of the Trust on September 30, 1998 were
$29,808,750 aggregate principal amount of the Company's Junior Subordinated
Debentures, together with the related accrued interest receivable thereon. The
Preferred Securities mature in 2027, and are treated as Tier 1 capital by the
Federal Reserve Bank of New York. The guarantees issued by the Company for the
Trust, together with the Company's obligations under the Trust Agreement, the
Junior Subordinated Debentures and the Indenture under which the Junior
Subordinated Debentures were issued, constitute a full and unconditional
guarantee by the Company of the Preferred Securities issued by the Trust.

     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income." This
pronouncement requires the Company to report the effects of unrealized
investment holding gains or losses on comprehensive income as displayed in the
Statement of Comprehensive Income.

     Effective July 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities." The Company elected to reclassify $212,735,000 of its held to
maturity securities as available for sale upon adoption of FAS 133. Of these
securities $17,424,000 was sold during the same reporting quarter, giving rise
to securities gains which are reported on the income statement as a cumulative
effect of change in accounting principal (FAS 133), net of tax in the amount of
$194,000.

NOTE B -- 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 three months ended September 30:

     Net income for the third quarter and first nine months of 1998 reached
record highs of $4.366 million and $11.956 million, up 3.1% and 3.4%,
respectively, over the comparable 1997 periods. Earnings per share (diluted)
also established new records of $.56 for the third quarter and $1.54
year-to-date, up at a slightly slower pace of 1.8% and 2.7%, respectively,
because of higher average shares outstanding. Compared to second quarter 1998
results, third quarter 1998 net income rose by $464,000 while earnings per share
climbed by $.06, both measures up by approximately 12%.

     Cash earnings per share increased to $.65 for the third quarter of 1998, up
1.6% compared to last year, and were 7.1% higher at $1.81 for the first nine
months. Cash or tangible return on assets (ROA) was 1.12% year-to-date while
nominal ROA was .95%. And tangible return on equity (ROE) at 15.52% exceeded
nominal ROE by 2.28 percentage points at 13.24% for the same period. The
difference between cash and nominal results reflects the contribution of the
company's branch acquisitions on an economic basis, which excludes the non-cash
impact of amortizing the premiums paid for the acquisitions.

     The company's record high results reflect continued progress in
strengthening our franchise following our mid-1997 acquisition of a combined 20
branches from Key Bank, N.A. and Fleet Bank. While loan growth slowed to a
comparatively modest $15.2 million during the third quarter, loans are up $82.5
million or 10% over the last twelve months, with growth in the purchased
branches contributing nearly half of this increase. Particularly important to
our third quarter results is an improvement in recurring fee income, up by 19.7%
compared to the same period last year. Net charge-offs at .52% of average loans
continued to decrease from an unusually high level for our company at .76% in
the fourth quarter of 1997.

     While the flat Treasury yield curve of the last nine months has put
downward pressure on yields especially in our investment portfolio, unrealized
gains in that portfolio remain substantial at $11.0 million, even after $460,000
in gains taken in the third quarter, $1.0 million in the second quarter, and
$266,000 in the first quarter. These gains resulted from investment strategies
involving $67 million in sales designed to improve the company's interest rate
risk position. As of July 1, 1998, the company moved virtually all its
held-to-maturity investment securities to its available-for-sale portfolio with
the adoption of Financial Accounting Standard 133; $328,000 of gains taken in
the quarter were from these transferred securities and are reported on an
after-tax basis at $194,000 as an extraordinary item.

     Approximately 65,000 shares have been acquired through quarter end under
the company's 750,000 stock repurchase program announced on September 17, 1998.
It is anticipated that program will result in meaningful improvements in
earnings per share and return on equity over time. The timing of repurchases is
being paced by using securities cash flow to pay down selected high cost
liabilities instead of reinvesting it in the currently unattractive financial
market environment.

     Reflective of pressure on the company's net interest margin compared to
last year at this time, third quarter net interest income was lower by 1.8% or
$300,000. Compared to second quarter 1998, however, net interest income is up by
$591,000 or 3.7% despite $9.6 million less in average earning assets. Yields on
earning assets remained largely unchanged while the cost of funds decreased by
over 1/8th of a point due to downward pricing of deposits and reduced
borrowings. Consequently, the net interest margin rose 13 basis points over the
linked quarter to 4.34%. Year-to-date, the net interest margin averaged 4.33%
versus 4.59% in 1997; including securities gains, the adjusted net interest
margin is 4.48% and 4.59%, respectively.

     Relative stability in earning asset yields for the third quarter compared
to the second quarter was achieved despite a decrease in overall financial
market rates. Declines were very modest in the overall loan and investment
portfolio yield, and the mix of earning assets held in investment securities was
reduced due to nearly $41 million in sales and run-off. During the quarter, the
company experienced a slight reduction in accelerated amortization of premiums
on certain collateralized mortgage obligations (CMOs) caused by unusually high
mortgage refinancing activity nationwide. Even with such activity during the
last nine months, the investment portfolio yield has averaged a favorable 127
basis point spread over the 3-year Treasury rate.

                                       13


     Loans increased during the third quarter by $15.2 million to $909 million
as of September 30, 1998. This growth represented about 40% of second quarter
1998's record growth, but exceeded the first quarter 1998 rate of $12.3 million,
which was reduced by the North Country ice storm and regular seasonal factors.
This quarter's growth entirely resided in business lending and consumer
mortgages, up $8.3 million and $8.1 million, respectively, or a bit more than
half their second quarter expansion. In general, commercial loan business
development efforts were less successful during the summer months, but the
success of the bank's no-closing cost residential mortgage program remained
good. Sales of mortgages in the secondary market were virtually the same as in
the second quarter at $11.1 million. Automobile model change-over and
conservative underwriting combined for a net decrease in indirect loans of $1.2
million. Consumer direct loans were unchanged.

     As the previously discussed reduction in net charge-off ratios suggests,
the dollar amount of net charge-offs was also reduced for the third consecutive
quarter to $1.177 million from $1.6 million in the fourth quarter of 1997.
Greatest improvement has occurred in direct installment loans followed by
indirect installment and commercial loans. The loan loss provision continues to
equally cover net charge-offs; there has been a 2 basis point decrease since
June 30, 1998 in the loan loss reserve to loans outstanding ratio to 1.37% due
to loan growth.

     Nonperforming loans at $4.4 million are virtually the same as one year
earlier, though the decrease in 90 day delinquencies has almost been equally
offset by higher nonaccruals. Compared to the level at June 30, 1998,
nonperformers are up $312,000 or 7.7%; nonaccruals are nearly unchanged with
higher delinquencies accounting for most of the increase. These flows reflect
what management believes to be normal changes within the portfolio due to
isolated situations and do not reflect any systemic problems; the ratio of
nonperformers to total loans increased slightly to .48% from three months
earlier, when it represented the very favorable 22nd peer percentile. Loss
reserve coverage over nonperformers is an ample 286% compared to the 250%
industry norm at June 30, 1998. Combined delinquencies (30 days or more) and
nonaccruals were 1.39% of total loans as of September 30, 1998 versus 1.82% at
year end, remaining well within the company's internal guideline of 2.0%.

     The company's third quarter 1998 efficiency ratio (overhead less intangible
amortization compared to net interest and other income before net securities
gains) improved to 57.2% from 60.8% in the second quarter. Favorable factors
were the increase in net interest income discussed above and a $383,000 increase
in noninterest income, largely comprised of $220,000 greater service charges and
overdraft fees (in part reflecting a mid-second quarter pricing increase), a 26%
increase in the company's annual dividend to $305,000 from its participation in
the New York State Bankers' Creditor Life Insurance program, $72,000 more in
fees from secondary mortgage market and student loan sales, and $39,000 more in
Visa merchant income. The efficiency ratio also improved because of a $172,000
reduction in overhead expense to $11.831 million; the second quarter 1998 level
had been elevated to $12.003 million from the first quarter rate of $11.494
million predominantly due to certain one-time or periodic expenses and timing
differences. The third quarter itself contains $150,000 in one-time expenses
relating to the sublease of a vacated acquired branch facility and write-down of
selected repossessed property (OREO).

     For the first nine months of 1998, the ratio of recurring noninterest
income to operating income was 18.6%, a significant 3.4 percentage point
increase over one year earlier, reflective of the company's strategy to increase
its income sources that are less susceptible to interest rate fluctuation. For
the same two periods, the company's recurring efficiency ratio was 58.7% this
year versus 55.9% for 1997, which includes only one quarter's impact of that
year's acquisitions.

YEAR 2000

      The year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have date-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions or engage in normal
business activities.

     Based on its assessment, the Company determined that the majority of its
processing systems are outsourced to industry standard vendors. The Company,
through its established Year 2000 Committee, has identified critical vendors and
processes and have put in place monitoring and measuring techniques to assure
our critical vendors are complying with the Federal Financial Institutions
Examining Council guidelines for Year 2000 compliance. The Company is subject to
quarterly reviews by the Office of the Comptroller of the Currency (OCC) and to
date there have been no significant findings as a result of their review. The
Company presently believes that with modifications to existing software and
conversions to new software, the year 2000 issue can be mitigated without impact
on the Company's operation.

     The Company has initiated formal communications with all of its significant
yet non-critical suppliers and large customers to determine the status of Year
2000 compliance and if appropriate contingency plans and business resumption
plans are in place in the event the vendor or customer should experience a Year
2000 compliant failure. To date, 56% of our vendors have responded that they are
Year 2000 compliant, 30% have reported that they are working diligently and will
be Year 2000 compliant, and 14% have not yet stated their position. We are
closely following the progress of those vendors who are working on the project
and will seek alternate vendors for all suppliers that can not become Year 2000
compliant or those vendors who have failed to respond to our inquiries.

     The Company is utilizing both internal and external resources to reprogram
or replace, test and validate the software for Year 2000 modifications. The
Company has estimated that the overall Year 2000 dollar expense for upgrades and
equipment will total up to $1,000,000. This budget estimate includes (but is not
limited to) upgrades to Item Processing software and hardware, ATM's, third
party reviews of outsourcing vendors, proxy testing, PC software and hardware,
the cost of service vendors mailings, follow-up testing, customer awareness
efforts and commercial customer risk assessments. The Company is working toward
completing the Year 2000 project by December 31, 1998. To date the Company has
incurred approximately $250,000 of expenses related to the assessment of, and
preliminary efforts in connection with, its Year 2000 project plan and
remediation effort.

     The costs of the project and the date on which the Company plans to
complete the Year 2000 modifications are based on management's best estimates
and efforts, which were derived utilizing numerous assumptions of future events
including the continued availability of certain resources, third party
modifications plans and other factors. There can be no guarantee that these

A)    The following table sets forth certain information concerning average
      interest-earning and interest-bearing liabilities and the yields and rate
      thereon. 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 amount
      earned include loan fees. Nonaccrual loans have been included in interest
      earnings for purposes of these computations.

                                                                        Third Quarters Ended September 30,

(1) The change in interest due to both rate and volume has been allocated to
volume and rate changes in proportion to the relationship of the absolute dollar
amounts of change in each.

(2) Changes due to volume and rate are computed from the respective changes in
average balances and rates of the totals; they are not a summation of the
changes of the components.

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.
