                 Community Bank System, Inc. and Subsidiaries
                  Notes to Consolidated Financial Statements

                                  (Unaudited)

                                June 30, 1999

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 six month period ended June 30, 1999
are not necessarily  indicative of the results that may be expected for the year
ended December 31, 1999.

     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 June  30,  1999  were
$31,998,262  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.

          Basic  earnings per share is computed  based on the  weighted  average
     shares  outstanding.  Diluted  earnings per share is computed  based on the

     assumed  exercise of stock  options  during the year.  The  following  is a
     reconciliation of basic to diluted earnings per share for the six and three

     Earnings per share (diluted) for second quarter 1999 reached $.55, a record
high for any second  quarter and up 10% over the prior  year;  for the six month
period,  earnings per share rose 7.1%. Net income for the quarter and first half
was $4.048  million  and $7.736  million,  up 3.7% and 1.9%,  respectively.  The
greater  improvement  in  earnings  per  share  reflects  fewer  average  shares
outstanding as a result of the Company's  share  repurchase  program.  Since its
inception last fall, over 495,000 shares or 6.5% of shares outstanding have been
bought back,  including  118,500  during the second  quarter.  Compared to first
quarter 1999 results, earnings per share (diluted) were $.05 or 10% higher while
net income was up $360,000 or 9.8%.

     Cash  earnings per share  (diluted)  for the quarter  increased to $.65, up
10.2% compared to last year.  Cash or tangible  return on assets (ROA) was 1.12%
versus nominal ROA at .96%. And tangible  return on equity (ROE) for the quarter
rose 62 basis points over one year earlier to 15.96%,  exceeding  nominal ROE by
2.30  percentage  points 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  for any  second  quarter  reflect  a
combination of continued  improvement  in net interest  margin to 4.48% from its
low of one year ago (up nearly 30 basis points),  resumption of loan growth from
being  unchanged  during  the first  quarter  (up 2.8%  since  March 31,  1999),
expansion of the Bank's investment  portfolio to take advantage of better buying
opportunities  as the yield curve  steepens (up 7.8% during the quarter to being
slightly higher than in mid 1998),  increased  noninterest  income (up 5.3% from
second quarter last year),  careful management of overhead (virtually  unchanged
from four  quarters  earlier),  and improved tax  planning  (reflected  in a 4.5
percentage  point  reduction  in  the  year-to-date   effective  tax  rate).  No
securities  gains were realized this quarter  compared to one year ago when $1.0
million was recognized as part of managing our  investment  portfolio on a total
return basis in that interest rate environment.

     Particularly important to the Company's results is that net interest income
(full tax  equivalent)  achieved its highest  level since fourth  quarter  1997,
having  improved for the second  consecutive  quarter to $17.1  million from the
1998 quarterly low in the fourth  quarter of $16.0  million.  Part of the reason
for the  improvement  was a 10 basis point  increase in the net interest  margin
during  the last three  months to 4.48%.  This  reflects  a better  yield on the
Company's   investment   portfolio  due  to  the  impact  of  reduced  principle
prepayments  on  the  Company's   collateralized   mortgage   obligation   (CMO)
securities;  in  addition,  there was a further 3 basis point  reduction  in our
overall cost of funds due largely to downward  pricing on selected  time deposit
maturities,  a trend which began in second quarter 1998.  Greater  earning asset
growth was also  important to improved  performance,  rising $71.7 million since
March 31, 1999  versus  $6.9  million  during the first  quarter.  Growth in the
investment portfolio contributed nearly two-thirds of this most recent increase.

     Second quarter  noninterest income (excluding net securities  gains/losses)
rose 5.3% from one year  earlier  to $3.9  million,  with  virtually  all of the
increase being related to general banking fees (overdraft fees,  deposit service
charges, and miscellaneous commissions), which rose over 12%. Financial services
income was unchanged:  Personal  trust fees and fees from the Company's  EBT/BPA
business,  which provides  investment  management,  pension  administration  and
consulting services,  were up modestly,  but an offsetting reduction occurred in
mutual fund commissions largely due to a lag caused by an operations  conversion
to the  Company's  own  broker/dealer  operation.  For  the  first  six  months,
financial  services  income rose  $292,000 or 12.5% while  general  banking fees
climbed  $529,000  or 12.3%.  Miscellaneous  income,  which  consists of various
periodic items,  was moderately lower  year-to-date  due to fewer  transactions,
such as the absence of an insurance  claim and gain on life  insurance  received
last year in the second and first  quarter,  respectively.  Noninterest  income,
excluding  transactions related to investment  securities and disposal of branch
properties,  as a percent  of  operating  income  rose to 18.8% in the first six
months of 1999 compared to 18.1% one year earlier.


                                       13




     Loans  rose  $25.5  million  during  the  quarter  to $942.4  million,  the
strongest  performance  since the $38.7  million  increase in last year's second
quarter and in sharp comparison to the first quarter's $316,000 decrease. During
the last twelve months,  loans have grown by $48.1 million or 5.4%; in addition,
$48.8 million in mortgages has been originated and sold in the secondary market,
resulting in total managed loan growth of 10.8%. Nearly half the growth in loans
outstanding  during the second quarter was in commercial loans at $12.6 million,
well in  excess  of the  increases  in the  preceding  three  periods.  Consumer
mortgages and indirect installment loans rose about equally,  accounting for 21%
($5.2 million) and 23% ($5.9 million),  respectively,  of the quarter's  growth.
Both  categories  reflected  a seasonal  pick-up  from the first  quarter,  with
indirect  loans (nearly all financing  new and used  automobiles)  showing their
first net increase in one year.  While showing a relatively  modest  increase at
$1.8 million,  consumer direct loans  (including home equity loans) rose for the
first time since the Company's mid-1997 branch  acquisitions.  In recognition of
rising interest rates, origination and sale of mortgages in the secondary market
were $8.8 million for the quarter,  less than half the first  quarter 1999 level
and $2.2 million less than in second quarter 1998.

     Nonperforming  loans  ended the  quarter  at $4.7  million or .50% of loans
outstanding, up $661,000 and .05%, respectively, from one year earlier. Based on
the  most  recent  peer  bank  data as of March  31,  1999,  when the  Company's
nonperforming  loan  ratio was .49%,  the  comparable  peer bank ratio was .74%,
ranking  CBSI in the  favorable  37th  percentile.  Compared to  year-end  1998,
nonperformers  have risen by nearly  $720,000  or 18%.  This change is more than
accounted for by two borrowers having combined  outstandings of nearly $900,000;
one loan has a partial Small Business Administration  guarantee and the other is
a defaulted  automobile  dealer  floor plan  identified  in early June now under
criminal  investigation.  Charge-offs  estimated at  approximately  $275,000 are
expected to be recognized  in the third  quarter when the necessary  details are
clarified.  In the  meantime,  a specific  loan loss  provision  of $317,000 was
established in the current quarter in anticipation of this determination.

     The ratio of loan loss  reserves to loans  outstanding  increased  slightly
during the quarter to 1.39%, resulting in coverage over nonperformers at 278%, a
level which management  believes to be adequate.  The ratio of delinquencies (30
days or more) and nonaccruals to total loans ended the quarter at 1.52%, up from
1.40% at year-end  1998 and 1.36% one year ago,  but well  within the  Company's
internal guideline of 2.0%.

     Loan loss  provision  expense  increased  to $1.4  million  for the  second
quarter, $118,000 above the same period last year and $252,000 more than for the
first three months of this year.  This increase is entirely due to the provision
for charge-offs anticipated in the third quarter on the two commercial customers
discussed above. Net charge-offs on installment loans have continued to steadily
improve both  absolutely,  down $728,000 or 31% for the first six months of 1999
versus 1998, and as a percentage of  installment  loans  outstanding,  averaging
almost one half point lower at 1.08%.  Combined net  charge-offs  on residential
and commercial  mortgages  remain  essentially  unchanged for the two periods at
approximately  .03% of  outstandings.  Total second quarter net charge-offs as a
percent of average loans were .41%. The second quarter  provision covered actual
net charge-offs by 1.48 times; when the anticipated charge-offs on the two above
commercial loans are considered,  coverage is 1.15 times.  Coverage in excess of
charge-offs  is being taken in 1999 as a precaution is the event the Upstate New
York  economy  weakens  after its long  sustained  period of  relative  economic
health.

     The Company's second quarter 1999 efficiency ratio (recurring overhead less
intangible  amortization  compared to net interest plus recurring  other income)
improved to 56.8% from 60.6% one year  earlier  and 59.0% in the first  quarter.
This  favorable  trend is a function  of several  factors:  an  increase  in net
interest margin due to a lower cost of funds and reduced premium amortization on
the Company's  CMO  securities,  growth in earning  assets,  steady  progress in
developing  more  sources  of  noninterest  income,  and  persistent  control of
overhead expense.  Second quarter overhead was virtually unchanged from one year
earlier and from first quarter 1999 levels.  For the first six months,  overhead
rose  $577,000  or 2.2%;  overhead  rose .6%  after  excluding  branch  disposal
expenses of $322,000  this year versus none in 1998 and $96,000 in write-offs of
fraudulent  installment  loans related to the defaulted  dealer floor plan noted
above.

Year 2000

     The Year 2000 issue is the result of computer  programs being written using
two digits rather the 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 Year 2000 Committee,  has identified  critical vendors and processes
and have put in place monitoring and measuring techniques to assure its critical
vendors are complying with the Federal Financial  Institutions Examining Council
guidelines for Year 2000 compliance.  In brief, the Company's loan,  deposit and
general ledger systems are outsourced to Fiserv, Inc.; the investment accounting
is outsourced to First  Tennessee  Bank;  ATM  processing is outsourced to U. S.
Bank Network  Services;  and the trust account system employs Sungard  software.
The Company is subject to quarterly  reviews by the Office of the Comptroller of
the  Currency  (OCC),  including  year 2000  compliance.  The Company  presently
believes that with the modifications to existing software and the conversions to
new software that have been  completed,  the year 2000 issue has been  mitigated
without impact on the Company's operations.

     The Company has completed formal communications with all of its significant
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  unlikely  event the vendor or  customer  should  experience  a Year 2000
compliant failure. To date, 86% of our vendors have responded that they are Year
2000  compliant,  8% have reported that they are working  diligently and will be
Year 2000  compliant  before  January 1, 2000 and 6% have not yet  stated  their
position  (additional vendors have been added since last reported).  The Company
is closely  following  the  progress  of those  vendors  who are  working on the
project and will seek alternative  vendors for all suppliers that can not become
Year 2000 compliant or those vendors who have failed to respond to the Company's
inquiries.

     The Company has utilized 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  between  $500,000 and  $1,000,000.  This budget  estimate
includes  (but is not  limited to)  expenditures  for  upgrades to software  and
hardware  for Item  Processing  as well as NCR  ATM's,  third  party  reviews of
outsourcing  vendors,  proxy  testing,  PC software  and  hardware,  the cost of
service vendor  mailings,  follow-up  testing,  customer  awareness  efforts and
commercial customer risk assessments.  The Company has completed all renovations
on critical systems. To date, the Company has incurred approximately $603,000 in
expenses,  funded through general  operations.  No major information  technology
projects  have been  significantly  delayed as a result of Year 2000  compliance
efforts.

     The costs of the project 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.  The
Company does not anticipate any material disruption of service;  however,  there
can be no guarantee that these estimates will be achieved.

Market Risk

     Market  risk is the risk of loss in a  financial  instrument  arising  from
adverse changes in market rates/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  which reviews and approves them  annually.  The Board of
Directors   delegates   responsibility  for  carrying  out  the  asset/liability
management policies to the  Asset/Liability  Committee (ALCO). In this capacity,
ALCO develops guidelines and strategies impacting the Company's  asset/liability
management  related  activities  based upon estimated  market risk  sensitivity,
policy limits, and overall market interest-related level and trends.

     At Community Bank System, Inc, 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 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 an up or down
200 basis point movement in rates from current levels.  While such an aggressive
movement in rates provides  management with good insight as to how the Company's
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 March 31,  1999.  In  addition to a 200 basis point
increase/decrease  in rates,  this analysis assumes a static,  no growth balance
sheet:

      Rate Change                   Estimated
      Basis Points       Net Interest Income Sensitivity

       + 200 bp                        .43%

       - 200 bp                      (1.54%)

     The Company does not anticipate  that results of the  sensitivity  analysis
based on June 30,  1999  data will  materially  differ  from the March 31,  1999
results.

     The  preceeding  interest  rate risk  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.  Furthermore,  the sensitivity  analysis
does not reflect  actions that ALCO might take in responding to or  anticipating
changes in interest rates.



                                       16



     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 June 30, 1999, this
ratio was 15.5% and 14.3%, respectively.

                            Supplemental Schedules

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

B)   The change in net interest income may be analyzed by segregating the volume
     and rate components of the changes in interest income and interest  expense
     for each underlying category.

     The volume and rate components of interest income and interest  expense for
     each underlying category are as follows:

(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.
