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

Note B -- Recent Events

          On January 29, 1997, Community Bank System, Inc. formed a wholly-owned
subsidiary,  Community Capital Trust I, a newly-formed  Delaware business trust.
The trust issued $30 million of 9.75%  Company-obligated  Mandatorily Redeemable
Capital  Securities,  Series A. The Company borrowed the proceeds of the Capital
Securities from its subsidiary by issuing Junior Subordinated  Debentures having
substantially  similar terms. The Capital Securities mature in year 2027 and are
treated as Tier I capital by the Federal Reserve Bank of New York.

      On March  10,  1997,  Community  Bank  System,  Inc.  redeemed  all of its
remaining  $4.5 million of 9.0%  Cumulative  Perpetual  Preferred  Stock at a 4%
premium from the proceeds of the issuance of its Junior Subordinated Debentures.

      A  two-for-one  stock  split was  approved  by  shareholders  at a Special
Shareholders  Meeting held on February 19, 1997.  Shareholders  of record at the
close of  business on February  10,  1997 were  issued one  additional  share of
common stock for each share already held on March 12, 1997.

          On June 16, 1997 CBSI's  acquisition  of eight  branches from KeyBank,
N.A.,  which included $149.9 million in deposits and $24.9 million in loans, was
completed.  In conjunction  with this  transaction,  the company received $109.1
million in cash net of $12.6 million in premium.

          After  the  close  of the  second  quarter,  on July 18,  1997  CBSI's
acquisition of 12 branches from Fleet Bank, N.A. was completed. This acquisition
included approximately $159.1 million in deposits and $65.2 million in loans. In
conjunction with this  transaction,  the company received $74.2 million in cash
net of $15.7 million in premium.

A.  Net Income Trend


      Net  income for the second  quarter  and first six months of 1997  reached
$3.668 million and $7.333  million,  up 4.1% and 10.1%,  respectively,  over the
comparable 1996 periods.  Earnings per share rose to $.48 for the second quarter
and $.95 for the first  half,  up at a  slightly  slower  pace of 4.3% and 9.2%,
respectively,  because of more shares outstanding. Return on equity increased 34
basis points to 13.79% for the first six months while tangible or cash return on
equity  reached  15.34%.  All per  share  results  have  been  adjusted  for the
company's 2 for 1 stock split effective March 12, 1997.

      Compared to first quarter 1997, this quarter's net income and earnings per
share were virtually unchanged, up $3,000 and $.01, respectively.  The per share
increase reflects the impact of the company redeeming the $4.5 million remainder
of its cumulative perpetual preferred stock on March 10, 1997





B. Balance Sheet Trends

      Our previously announced acquisition of eight branches from KeyBank, N.A.,
which  included  $149.9  million in  deposits  and $24.9  million in loans,  was
successfully  completed  in  mid-June.  Even  without the impact of the acquired
loans, this quarter's loan growth was the strongest in the company's history and
nearly 60% more than in second quarter 1996. During the past year, loans (before
the June branch  acquisition)  have  climbed a record  18.6%,  over one third of
which came from new markets  opened by our mid-1995  branch  purchases  from The
Chase Manhattan Bank, N.A.

      Loans  outstanding  increased  by $61.7  million or 9.2% during the second
quarter.  Excluding the loans purchased from Key,  outstandings  rose by 5.5% or
$36.8 million, significantly better than the $23.0 million or 4.0% growth during
second  quarter 1996.  The primary  components of the $83.4 million  increase in
loans since  year-end  1996 to $735.9  million are indirect  consumer  loans (up
$22.2 million to $189.8 million),  predominantly reflecting automobile financing
through an  established  dealer  network;  business  lending  products (up $37.4
million to $248.5  million),  due to expanded  floor plan lending to  automobile
dealers and higher  commercial  loans ($17.1 million from Key);  consumer direct
loans (up  $18.9  million  to $141.0  million),  reflecting  selected  growth in
installment  and personal loans ($7.8 million from Key); and consumer  mortgages
(up $4.9 million,  net of $2.9 million in originations sold  service-retained in
the  secondary  market),  growth of which  picked up during the  second  quarter
because of seasonal buying and lower financial market rates.

      Investments (excluding market value adjustment) totaled $606.6 million for
the quarter  just ended,  down $2.3  million  (less than 1%) from March 31, 1997
attributable to the lack of favorable buying opportunities. Since June 30, 1996,
there has been $32.1 million  (5.6%) in investment  growth,  which was initially
almost  entirely  funded by a variety of capital market  borrowings and has been
replaced with the acquired deposits.

      Total deposits have increased $171.5 million (16.2%) since March 31, 1997,
largely due to the deposits  acquired from the Key branches (at quarter end) and
inflows of municipal deposits. Reflecting the same circumstances, total deposits
are up $210.1 million or 20.6% during the last twelve months.





C. Income Statement Trends

      Major  positive  factors for the second  quarter versus first quarter 1997
were an increase in net interest income of $215,000 on a $62.2 million expansion
in earning  assets,  albeit at temporarily  lower margins until pending  deposit
acquisitions closed; a $204,000 improvement in noninterest income from a variety
of sources (only $27,000 reflecting the Key branch acquisition); and the absence
of dividends paid on the company's  cumulative  perpetual preferred stock, which
was redeemed in mid-March.  Offsetting  these  improvements was a combination of
$216,000  more in  noninterest  expense  (including  $213,000  more in  one-time
acquisition-related  expenses), a $120,000 higher loan loss provision expense (a
relatively modest increase because of an ample loan loss reserve),  and a slight
increase in the company's tax rate.

      Second  quarter net interest  income rose 7.3% or $1.0 million  versus the
prior year. The improvement reflects $171 million more in earning assets, 65% of
which represents  continued steady loan growth throughout the last twelve months
and an additional  15% due to loan growth  provided by the Key branch  purchase.
Almost 90% of earning asset growth was funded by the deposits acquired from Key,
which  enabled a $17.5 million  reduction in  borrowings  from one year earlier,
with the balance of the funding from higher  levels of consumer,  business,  and
municipal  time  deposits.  The  company is expected  to have the  capacity  for
earning asset growth and/or the potential to pay down more of its capital market
borrowings and other large  liabilities with the lower cost deposits of 12 Fleet
Bank branches scheduled to be acquired in July. These temporarily higher funding
costs,  in addition to the interest on CBSI's 9.75% Trust Preferred stock issued
in January 1997, resulted in a second quarter net interest margin of 4.48%, a 42
basis point  decrease from one year ago.  Comparing the first six months of 1997
to the same 1996 period,  net interest income climbed 8.1% or $2.2 million,  and
the net interest margin averaged 40 basis points lower at 4.57%.

      Second quarter  noninterest  income rose nicely, up over 26% from one year
earlier,  primarily  due to  improved  sales  of  mutual  funds  as  well as the
contribution of our July 1996 purchase of Benefit Plans  Administrators (BPA) of
Utica, NY.

      The company's second quarter 1997 efficiency  ratio (overhead  compared to
recurring  operating  income) was up 2.9 percentage points from one year earlier
to 60.6% but  unchanged  from the first  quarter 1997 level.  Compared to second
quarter 1996,  recurring  operating income (net interest income plus noninterest
income) rose by 9.6%--a  somewhat reduced rate due to earning asset growth being
temporarily  supported by higher cost funds--while  overhead increased by 12.7%.
Noninterest  income  increased  10.8% before the  contribution  of BPA's pension
administration revenues and associated investment management fees earned through
CBNA's trust  department.  Excluding the combined impact of BPA and related CBNA
expenses  in both  years  and  one-time  expenses  of the Key and  Fleet  branch
acquisitions,  second quarter noninterest  expense rose 9.1%,  reflecting annual
personnel expense increases, the impact of stock-based director compensation,  a
one-time filing fee, higher advertising  expense, an increase in certain problem
asset costs, and higher  intangible  amortization  expense due to the Key branch
acquisition.  The  second  quarter  efficiency  ratio  excluding  the  impact of
intangibles rose 3.2 percentage points to 56.5% from a year earlier.

      Despite  higher  pretax  income,  first  half 1997  income  taxes  fell by
$286,000  from  the  same  1996  period  because  of  increases  in  non-taxable
investment  income.  As a result,  the  effective  tax rate was reduced to 36.9%
versus 40.7% one year earlier. CBSI's marginal tax rates are 35% for federal and
9% for state tax purposes.





D. Asset Quality Trend

      Asset quality  remains good;  though the ratio of net charge-offs to loans
rose 17 basis points in the second quarter to .39%, the ratio of  non-performing
loans to loans  outstanding  was up only slightly to .48%, the latter still less
than half the level of peer banks nationwide based on data available as of March
31, 1997.

      Second  quarter 1997 loan loss  provision  expense rose by $241,000 or 40%
over the prior  year's  level,  resulting  in a $383,000 or 32%  increase in the
provision for the first six months.  Year-to-date  net charge-offs rose $432,000
or 61% to $1.1 million,  resulting in a net charge-offs to average  outstandings
ratio of .34% for the period  versus .24% in 1996.  Consumer  installment  loans
accounted for all but 5% of the change. The loan loss reserve/loans outstandings
ratio rose 5 basis points during the quarter to 1.30%,  reflecting 125% coverage
of the provision over net  charge-offs as well as the addition of a $1.0 million
valuation  allowance  resulting  from  intensive  credit  review  of  the  loans
purchased from Key.  Nonperforming loans rose $209,000 during the second quarter
to $3.505  million,  a level  $730,000  or 26% higher  than one year ago;  about
three-quarters  of the latter increase  pertains to consumer  installment  loans
with the balance in commercial loans.

      Despite  some recent  softening  in the  company's  asset  quality  ratios
compared to the highly  favorable  net  charge-off  experience  of 1993-1996 and
nonperforming  loan  levels of 1995,  today's  loan  portfolio  credit  strength
remains  better  than  industry  norms;   as  of  March  31,1997  data,   CBSI's
nonperforming  loans/loans  outstanding  ratio was in the very  strong 20th peer
percentile.  Combined delinquencies and nonaccruals were 1.42% of total loans at
quarter  end  compared  to 1.27% one year  earlier  and  1.46% at year end,  all
measures well within the company's  internal  guideline of 2.0%. Besides present
coverage of the loan loss reserve over nonperformers being 2.7 times versus peer
bank  coverage  of 2.2  times  as of March  31,  1997,  over  $1.25  million  or
approximately 13% of the reserve is available for absorbing general,  unforeseen
loan losses after allocation by specific customer and loan type.





E. Capital and Other Trends


      As of June 30,  1997,  the tier I leverage  ratio was 6.93%  versus  5.65%
twelve months  earlier.  The large increase in the ratio is  attributable to the
impact of the issuance of $30 million in Trust  Preferred  securities  offset by
the  redemption in early March of the remaining  45,000 shares ($4.5 million) of
more expensive cumulative perpetual preferred stock. Growth in the present ratio
also  considers the favorable  earnings  during the last 12 months and scheduled
amortization of intangible assets, partially offset by the continued strategy to
leverage the balance  sheet when  attractive  investment  opportunities  present
themselves.  Compared to December  31,  1996,  the ratio was up 1.04  percentage
points due to the Trust Preferred  offering,  first half earnings and intangible
amortization,  partially offset by investment  growth funded with capital market
borrowings.

      As a result of the aforementioned  reasons,  the tier I risk-based capital
ratio of June 30, 1997 was 11.67%,  or 106 basis points higher than it was as of
June 30, 1996. This compares to a 6% "well-capitalized " regulatory minimum.

      Book value per share increased 9.5% from June 30, 1996 to $14.69 as of the
most recent quarter end, while tangible book value per share (which additionally
reflects  intangible  amortization)  has fallen slightly to $8.92,  down $.07 or
less than 1% over the same  period  due to the  intangibles  related  to the Key
acquisition.

      The bank's  liquidity  level is very favorable as of June 30, 1997. In the
event of a liquidity  crisis,  more than $285  million  (essentially  short term
assets minus short term  liabilities) or 20.2% of assets could be converted into
cash within a 30-day time  period.  Over a 90 day time  period,  19.3% of assets
could be converted to cash.

      As  shown  by  the  statement  of  cash  flows  preceding  the  Management
Discussion and Analysis, the bank's cash and cash equivalents increased by $14.5
million  during the first six months to $67.0  million  as of June 30,  1997,  a
level $17.6 million higher than one year earlier.  The increase in cash and cash
equivalents  during the first half of 1997 reflects asset expansion  (about half
of which related to net growth in investment securities) being entirely financed
by deposit  growth and  issuance  of the Trust  Preferred  securities.  Net cash
provided  by  operating  activities  during  the  first  half of 1997 is  almost
entirely responsible for the increase in cash and cash equivalents.





II.   SUPPLEMENTAL INFORMATION TO EARNINGS PERFORMANCE SUMMARY

      The  following  sections of this report  discuss more fully certain of the
balance sheet and earnings trends summarized above.

A. Net Interest Income

      Changes in net interest income reflect changes in both net interest margin
and earning asset levels.

      On a  tax-equivalent  basis,  net interest  income for second quarter 1997
increased  $975,000  (7.1%)  over the same 1996  period to $14.7  million.  This
reflects a $190.2 million (16.9%) increase in average earning assets with $108.5
million in loan growth and $81.7 million in investment  growth. The net interest
margin  was 42 BP lower  than a year  earlier . This was  largely  due to the 52
basis point (BP) higher cost of funds  resulting from a $120.8 million  increase
in average capital market borrowings, which included the aforementioned issuance
of the $30 million of 9.75% Trust  Preferred  stock. An 8 BP increase in earning
asset yields offset a portion of the cost of funds increase.

      Compared  to first  quarter  1997,  there was a $200,000  increase  in net
interest income.  The change is attributable to earning asset growth,  partially
offset by the 14 BP lower net  interest  margin  largely  due to the  absence of
$321,000 in  non-recurring  income  recognized in the prior  quarter.  Excluding
first quarter non-recurring income, the second quarter net interest margin would
have been 4 BP lower versus 14 BP lower.





      The table below shows these underlying dynamics.

 * May not foot due to rounding

      Despite the high  proportion  (89th peer  percentile) of the bank's assets
being in investments  (whose yields are  relatively low compared to loans),  and
greater funding costs caused by both temporarily  higher levels of borrowings in
advance  of the  pending  branch  acquisitions  and  interest  on  CBSI's  Trust
Preferred  stock  issued  in  January  1997,  the net  interest  margin is still
slightly  better than the norm being in the 54th peer percentile as of March 31,
1997.  This is  attributable to high earning asset yields being in the favorable
80th  percentile,  offset by a temporarily  high cost of funds being in the 73rd
percentile.

      CBSI's stock closed second quarter 1997 at $28.25,  up 81.5% from one year
earlier  when it closed at $15.57.  The volume of shares  traded at 712,647  was
59.4% more than during  second  quarter 1996,  due largely to NASDAQ's  standard
practice of not adjusting the historical volume of shares traded in the event of
a stock split.

      The cash dividend  shown above reflects a 1.5 cent (9%) per share increase
in the  quarterly  dividend per common share that was effective in third quarter
1996.  This most recent  increase was the sixth  dividend  increase  within five
years.  The 1997 common  dividend  payout of 37.0% has increased  slightly (with
higher  earnings)  from the same 1996  period but remains  within the  company's
targeted 30-40% guideline.





C.   Loans

      Loans  outstanding,  net of  unearned  discount,  reached a record  $735.9
million as of June 30, 1997, a very favorable $ 136.3 million  (22.7%) growth in
the last twelve  months.  The $61.7 million in quarterly  growth from the end of
the first quarter to the end of the second quarter ($24.9 million resulting from
the  former  Key  branches)   represents  the  20th  consecutive   quarter  that
oustandings  have grown.  As shown in the table below,  CBNA is  predominantly a
retail bank,  with more than 66% of its  outstandings  spread across three basic
consumer loan types.

      More than 44% of the bank's  loan  growth in the last  twelve  months came
from the generally prime-based business lending portfolio, which increased $59.7
million  or  31.6%,  reflecting  strong  business  development  efforts  and the
contribution of acquired branches amounting to $17.1 million in commercial loans
at quarter end. Even without the former Key loans,  business  lending would have
increased 22.5%.

      Almost 30% of the bank's loan  growth in the last twelve  months came from
the indirect lending portfolio (applications taken at dealer locations - none of
which came from the former Key branches),  which grew 27.2%.  This reflects good
automobile demand  industry-wide,  as well as continued greater emphasis on this
product line in the bank's Southern Region.

      The  remaining  growth over this period  resulted  from a 33.1%  growth in
consumer direct loans  (applications taken at branch locations - $6.4 million of
the $35.0 million in growth  resided in the former Key branches) and less than a
1% increase in  Consumer  Mortgages  (none from Key  branches).  Both  increases
reflect a change in late October 1996 to reporting  fixed rate Home  Equities in
Consumer Direct Loans instead of Consumer Mortgages.

      Despite a 25 BP increase in the average prime rate, the average loan yield
for the quarter  just ended is 4 BP lower than a year ago  primarily  due to the
increasing mix of relatively  lower yielding  business loans (as compared to the
higher  yielding  consumer  loans)  and  lower  yields  on  consumer   mortgages
reflective of financial market trends.





D.  Asset Quality

      The following table reflects the detail of non-performing and restructured
loan levels.  The ratio of non-performing  assets to total assets was .29% as of
June 30,  1997,  up 4 basis  points  from a year ago.  OREO for all  periods  is
recorded at the lower of cost or market less  estimated  cost to sell. The ratio
of  nonperforming  assets to loans  plus OREO at .58%  remains  better  than the
company's  internal goal of less than .75%.  Nonaccruing  loans rose $274,000 or
14.8%,  about equally due to consumer  installment  and real estate  loans.  The
change in loans delinquent 90 days or more reflects some softening in commercial
and consumer installment loans.

The table below  reflects  quarterly and  year-to-date  charge-off  and recovery
trends.  As previously  discussed  year-to-date net charge-offs rose $432,000 or
61% to $1.1  million,  resulting in a net  charge-offs  to average  outstandings
ratio of .34% for the period  versus .24% in 1996.  Consumer  installment  loans
accounted  for all but 5% of the change.  As shown in the table on the  previous
page, the loan loss reserve/loans  outstandings ratio rose 5 basis points during
the  quarter  to 1.30%,  reflecting  125%  coverage  of the  provision  over net
charge-offs  as well  as the  addition  of a $1.0  million  valuation  allowance
resulting from intensive credit review of the loans purchased from Key.

      Average deposits increased $65.7 million or 6.3% for the 1997 quarter just
ended as compared to the same 1996 quarter.  Due to relative lateness of the Key
acquisition in the second  quarter,  the $145 million in Key branch deposits had
an impact on average deposits of approximately $25 million. Overall decreases in
Savings and Money  Market  accounts  were offset by a large  increase in average
time  deposits  ($75.0  million  increase - of which  almost $12  million of the
average was related to the former Key branches), reflecting the bank's objective
to extend its deposit  liabilities  by offering  very  competitive  rates on its
Certificates of Deposit.

      Due largely to the growing  mix of higher cost time  deposits  (upon which
the rate is also  increasing)  and an average  Fed Funds rate  moving up 30 BP's
from  second  quarter  1996 to second  quarter  1997 (which  influences  certain
deposit  pricing),  the average total deposit rate moved up 22 BP's.  The higher
time deposit mix also reflects the  continuing  flow of Savings and Money Market
deposits back into Time Deposits as rates have become more attractive.

      Borrowings  for second quarter 1997 averaged  $195.0  million  compared to
$74.0 million for second  quarter 1996.  The increase  resulted in part from the
issuance of $30 million of Capital  Securities in anticipation of funding future
branch   deposit   acquisitions   and  repaying  the  company's  more  expensive
outstanding  preferred  stock.  Average loans grew $108.5 million (18.4%) in the
last year while average investments grew $81.7 million (15.3%); about 64% of the
combined  increase was funded with capital  market  borrowings,  a large part of
which the bank has the capacity to repay from the acquired branch deposits.




G. Investments and Asset/Liability Management

      The investment portfolio at quarter end comprised 45.3% of earning assets,
down from 48.9% on June 30, 1996, primarily because of the planned faster growth
of the loan portfolio  versus the investment  portfolio.  Largely  through fixed
rate investment  purchases,  the absolute level of the investment  portfolio has
grown by $35.0 million or 6.1% during the last twelve months.

      As shown by the table below, the bank's  investments  consist primarily of
U.S. Treasury securities,  mortgage-backed  securities  (including U.S. agencies
and collateralized  mortgage  obligations),  and tax-exempt obligations of state
and political subdivisions.

      The average fully taxable  equivalent  yield in the last year (as shown in
the table in  section  F) has  increased  20 BP to 7.67% on  average  for second
quarter 1997 versus  7.48% for second  quarter  1996,  largely due to a $126,000
bond  discount  accretion  adjustment  (earned  when $ 7.9 million in bonds were
called).

      The portfolio  market value  increased  from 100.4% of book value one year
ago to  101.7%  of book  value  as of June 30,  1997.  The  average  life of the
portfolio  increased  slightly  from 4.2 years on June 30,  1996 to 4.3 years on
June 30, 1997.

      As of the most recent quarter end,  43.1% of the investment  portfolio was
classified as available-for-sale (AFS) in accordance with SFAS No. 115, with the
remainder (56.9%) as held-to-maturity. The pretax market value adjustment of the
AFS  portfolio  was a  favorable  $3.0  million as  compared  to $107,000 a year
earlier.
