A. Net Income Trend

      Net income for the third  quarter  and first nine  months of 1997  reached
record  highs of  $4.235  million  and  $11.567  million,  up 11.7%  and  10.6%,
respectively,  over the comparable 1996 periods.  Earnings per share were also a
record,  rising to $.55 for the third quarter and $1.50  year-to-date,  up 10.0%
and 10.3%,  respectively.  Third  quarter  return on equity  increased  31 basis
points to 15.01%,  bringing  the nine month  level to 14.22% or 16.06%  based on
tangible or cash return on equity.  All per share results have been adjusted for
the company's 2 for 1 stock split effective March 12, 1997.


      The  results  reflect  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  purchases  added  approximately  $309 million in deposits (or 22% of our
quarter-end  deposit  base) and $90 million in loans (or 11% of our  quarter-end
loan base).  During the past year, loans (before the summer  acquisitions)  have
climbed a record 17.6%,  three-eighths  of which came from new markets opened by
our mid-1995  branch  purchases from The Chase Manhattan Bank, N.A. In addition,
third quarter noninterest income rose nicely, up over 39% from one year earlier.
While over  one-third of the increase  reflects the impact of the  acquisitions,
fees related to fiduciary services, benefit plan administration, and mutual fund
sales, all areas of priority strategic focus, were up a combined 13.2%.

      Nearly $450,000 in non-recurring acquisition expenses were incurred during
the quarter. The company was more than able to offset them by $321,000 in income
accretion  resulting  from $29.5 million in called bonds as well as a three-fold
increase in the annual dividend on its creditor life insurance program.  Lastly,
asset quality remains  acceptable.  Though the ratio of net charge-offs to loans
rose 10 basis points in the third  quarter to .49% and is 30 basis points higher
than the prior year's abnormally low level, the ratio of non-performing loans to
loans  outstanding was up only slightly to .53%, the latter still  approximately
half the level of peer banks  nationwide  based on data available as of June 30,
1997.

      Compared to second  quarter 1997,  this quarter's net income rose $567,000
or 15.5% while earnings per share were up $.07 or 14.8%.  Major positive factors
were an  increase  in net  interest  income of $2.2  million  on a $124  million
expansion in average earning assets, representing nearly a full-quarter's impact
of the Key and Fleet  branch  acquisitions,  and an  $868,000  increase in other
income, of which $243,000  reflects the annual creditor life insurance  dividend
and $336,000  reflects the  acquisitions.  Offsetting  these  improvements was a
combination  of $1.4 million more in operating  expense,  including  $229,000 of
added  one-time   acquisition-related   expenses;  $436,000  greater  intangible
amortization  generated  by the  acquisitions;  and a $385,000  higher loan loss
provision expense, maintaining 125% coverage of net charge-offs as in the second
quarter.

      Third  quarter net interest  income rose 18.1% or $2.6 million  versus the
prior year. The improvement reflects $203 million more in earning assets, 55% of
which represents continued steady loan growth throughout the last twelve months,
with the balance due to loan growth provided by the two branch acquisitions. The
company's investment  portfolio was unchanged at $595 million.  Asset growth was
funded by the deposits acquired from Key and Fleet, which enabled a $101 million
reduction in borrowings  from one year earlier,  with the balance of the funding
largely from higher levels of consumer,  business,  and municipal time deposits.
The third  quarter net  interest  margin at 4.67% was 15 basis points lower than
one year earlier or 24 basis points less after  excluding the called bond income
accretion.  The reduction  largely  represents a higher overall cost of deposits
due to more  competitive  rates paid on and greater mix of money market and time
deposits,  and the cost of $30 million of 9.75% Trust  Preferred stock issued in
January  1997.  Comparing the first nine months of 1997 to the same 1996 period,
net interest  income climbed 11.5% or $4.7 million,  and the net interest margin
averaged 32 basis points lower at 4.59%.

      The company's  third quarter 1997 efficiency  ratio (overhead  compared to
recurring  operating  income) was up 2.9 percentage points from one year earlier
at   60.4%.   Excluding   non-recurring   bond   income   accretion,    one-time
acquisition-related  expenses,  and 1996's SAIF  insurance  fund  assessment  of
$263,000, the third quarter efficiency ratio was 59.1% this year versus 55.9% in
1996.  Compared to third quarter 1996,  recurring operating income (net interest
income before called bond income accretion,  plus noninterest  income before net
securities gains) rose by 19.2% while overhead  (excluding  one-time expenses in
both  years)  increased  by 26.0%.  The bulk of the higher  noninterest  expense
reflects  personnel  increases related to branch expansion (both acquired branch
staff and  volume-sensitive  positions in operations  and other areas to support
the expanded  balance  sheet),  greater data processing  requirements,  expanded
facilities costs,  more office supplies and advertising,  an increase in certain
problem asset costs, and higher intangible amortization. Excluding the impact of
intangibles from the efficiency ratio calculation  improves the ratio by 5.6 and
4.1 percentage points in 1997 and 1996, respectively.


      Despite  higher  pretax  income,  taxes for the first nine  months of 1997
taxes fell by $423,000 from the same 1996 period because of lower New York State
taxes on 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 for both years.

B. Balance Sheet Trends

      Loans  outstanding  increased  by $91  million  or 12.4%  during the third
quarter.  Excluding the loans purchased from Fleet, outstandings rose by 3.5% or
$26 million  compared to growth of $37  million  (before the Key loan  purchase)
during second quarter 1997 and $27 million during third quarter 1996.  About 60%
of the reduction in growth versus the spring  quarter is due to slower  indirect
loan growth,  with the balance due to reduced  direct  installment  and business
loan growth.

      The primary components of the $200 million increase in loans over the last
twelve  months to $827 million are consumer  direct loans (up $84 million or 77%
to $193 million), with almost half the growth due to home equity loans purchased
from  Fleet and nearly 10% due to the Key  direct  installment  loan  purchases;
business  lending  products (up $80 million or 41% to $277 million),  with about
$17  million  each in  purchases  from Key and Fleet,  nearly $6 million  due to
expanded  floor plan lending to automobile  dealers,  and $47 million in general
purpose  borrowing;  indirect  consumer  loans  (up $36  million  or 23% to $196
million),  predominantly  reflecting automobile financing through an established
dealer network (no loans purchased from Key and Fleet); and consumer  mortgages,
virtually unchanged from one year earlier at $161 million due to $7.4 million in
originations sold service-retained in the secondary market and regular portfolio
paydowns.


      Investments (excluding market value adjustment) totaled $593.6 million for
the  quarter  just  ended,   down  $13.0  million  (2.1%)  from  June  30,  1997
attributable to the lack of favorable buying opportunities.  Since September 30,
1996, there has been a $1.6 million (less than 1%) investment decline, which was
caused   largely   by  called   bonds  and   limited   attractive   reinvestment
opportunities.

      Total average  deposits for September 1997 are $224 million (19.2%) higher
than average June 1997 deposits due largely to a full month's  impact of the Key
branches  acquired in Mid-1997 and the deposits acquired from the Fleet branches
(mid-July) . Primarily reflecting the Fleet and Key Branch  acquisitions,  total
average  deposits for September  1997 are up $356.4 million or 34% over the same
1996  period.  Excluding  the  impact  of the two  acquisitions,  total  average
deposits  are up $40 million or 3.9% . Average IPC  deposits  excluding  Key and
Fleet  are up $31  million  or 3.4% due  primarily  to growth  in  business  and
individual CD's less than $100,000.

Asset Quality Trend

      Third  quarter  1997 loan loss  provision  expense rose by $605,000 or 96%
over the prior  year's  level,  resulting  in a $988,000 or 54%  increase in the
provision  for the first nine months.  Year-to-date  net  charge-offs  rose $1.1
million  or 113% to $2.1  million,  resulting  in a net  charge-offs  to average
outstandings  ratio  of .39%  for the  period  versus  .23%  in  1996.  Consumer
installment  loans  accounted  for all  but 12% of the  change.  The  loan  loss
reserve/loans  outstandings  ratio rose 20 basis  points  during the  quarter to
1.50%, reflecting 125% coverage of the provision over net charge-offs as well as
the addition of a $2.5 million  valuation  allowance  resulting  from  intensive
credit  review of the loans  purchased  from  Fleet.  Nonperforming  loans  rose
$857,000 during the third quarter to $4.362  million,  a level $1.150 million or
36% higher  than one year ago;  about 85% of the  latter  increase  pertains  to
consumer installment loans with the balance in real estate mortgages.

      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  June  30,  1997  data,   CBSI's
nonperforming  loans/loans  outstanding  ratio was in the very  strong 21st peer
percentile.  Combined delinquencies and nonaccruals were 1.72% of total loans at
quarter  end  compared  to 1.31% one year  earlier  and  1.46% at year end,  all
measures  well within the  company's  internal  guideline of 2.0%.  In addition,
CBSI's present coverage of the loan loss reserve over nonperformers is 2.8 times
versus  2.3 times  based on peer data as  available  of June 30,  1997.  Lastly,
management  is confident  that an ample  portion of the reserve ($2.2 million or
17.5%)  is  available  for  absorbing  general,  unforeseen  loan  losses  after
allocation by specific customer and loan type.

Capital and Other Trends

      As of September 30, 1997, the tier I leverage ratio was 5.32% versus 5.65%
twelve months earlier.  The decrease in the ratio is attributable to intangibles
resulting from the Key and Fleet acquisitions  partially offset by the impact of
the issuance of $30 million in Trust Preferred securities (net of the redemption
in early March of the remaining  45,000 shares ($4.5  million) of more expensive
cumulative perpetual preferred stock). The decline was also limited by favorable
earnings  during the last 12 months and  scheduled  amortization  of  intangible
assets.

      As a result of the aforementioned  reasons,  the tier I risk-based capital
ratio of September 30, 1997 was 8.92%,  or 165 basis points lower than it was as
of September  30, 1996.  This  compares to a 6%  "well-capitalized  " regulatory
minimum.

      Book value per share  increased 11.4% from September 30, 1996 to $15.16 as
of the most recent  quarter  end,  while  tangible  book value per share fell to
$7.15, down 23.3% over the same period due to the added  intangibles  related to
the Key and  Fleet  acquisitions,  net of  intangible  amortization  related  to
previous acquisitions.

      The bank's  liquidity level is very favorable as of September 30, 1997. In
the event of a liquidity crisis, more than $251 million  (essentially short term
assets minus short term  liabilities) or 15.8% of assets could be converted into
cash within a 30-day time  period.  Over a 90 day time  period,  14.5% 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 $22.6
million  during the first nine months to $75.1 million as of September 30, 1997,
a level $22.5  million  higher than one year  earlier.  The increase in cash and
cash  equivalents  through  nine months of 1997  reflects  the excess of deposit
growth,  issuance  of the  Trust  Preferred  securities,  and cash  provided  by
operating activities over asset growth (almost 80% of which relates to increased
loans).





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 third  quarter 1997
increased $2.6 million or 18.0% over the same 1996 period to $16.9 million. This
reflects a $252.7 million (21.3%) increase in average earning assets with $188.7
million in average loan growth and $64.0 million in average  investment  growth.
The net interest margin was 15 BP lower than for the same 1996 quarter despite a
28.5%  reduction in capital  market  borrowings to $103.6  million.  The primary
reason for the lower  margin was the 13 basis  point (BP)  higher  cost of funds
resulting  from the  aforementioned  issuance  of the $30 million of 9.75% Trust
Preferred  stock and a greater  mix of and  higher  overall  rates paid on money
market and time  deposits.  A 9 BP increase  in earning  asset  yields  offset a
portion of the cost of funds increase.

      Compared to second quarter 1997,  there was a $2.3 million increase in net
interest income. The change is attributable to earning asset growth plus a 19 BP
higher net interest margin, which was largely due to a 24 BP lower cost of funds
reflecting a portion of borrowings  replaced with relatively lower cost acquired
deposits.






      The table  below  shows  these  underlying  dynamics  of the change in net
interest income.

 * May not foot due to rounding

      Despite the high  proportion  (85th peer  percentile) of the bank's assets
being in investments  (whose yields are relatively low compared to loans), and a
greater funding cost (71st peer percentile) caused in part by interest on CBSI's
Trust  Preferred  stock issued in January 1997, the net interest margin is still
at the peer norm, being in the 52nd peer percentile as of June 30, 1997. This is
attributable   to  high  earning  asset  yields  being  in  the  favorable  70th
percentile.  Again, the margin has increased since the end of June  (comparative
date) by 19 BP and should now look even more favorable in peer comparisons..

      CBSI's stock closed third  quarter 1997 at $29.00,  up 69.3% from one year
earlier  when it closed at $17.13.  The volume of shares  traded at 588,796  was
32.0% 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 2 cent (11.1%) per share increase
in the  quarterly  dividend per common share that was effective in third quarter
1997.  This most recent  increase was the seventh  dividend  increase within six
years.  The 1997 common  dividend  payout of 36.5% has increased  slightly (with
higher  earnings)  from the same 1996  period and remains  within the  company's
targeted 30-40% guideline.





C.   Loans

      Loans  outstanding,  net of  unearned  discount,  reached a record  $826.9
million as of  September  30,  1997, a very  favorable $ 200.2  million  (31.9%)
growth in the last twelve  months of which $90.1  million were acquired from Key
and Fleet.  The $91.0  million in  quarterly  growth  from the end of the second
quarter to the end of the third quarter ($65.2 million  resulting from the loans
acquired from the former Fleet branches) represents the 21st consecutive quarter
that  outstandings  have increased.  As shown in the table below,  CBNA is still
predominantly a retail bank, with 66.6% of its outstandings  spread across three
basic consumer loan types.

      More than 42% or $84.0  million  of the bank's  growth in the last  twelve
months came from  consumer  direct loans,  of which $55.3 million  resulted from
acquired loans. In addition, the increase reflects a change in late October 1996
to reporting fixed rate Home Equities in Consumer Direct Loans (recognizing them
as a substitute  for  conventional  installment  borrowing)  instead of Consumer
Mortgages.  This reclassification accounts for the decline in consumer mortgages
- - no mortgages were acquired.

      More than 40% of the bank's  loan  growth in the last  twelve  months came
from the generally prime-based business lending portfolio, which increased $80.4
million  or  41.0%,  reflecting  strong  business  development  efforts  and the
contribution of the acquired branches,  amounting to $34.8 million in commercial
loans at quarter  end.  Even  without the former Key and Fleet  loans,  business
lending would have increased 23.2%.

      Almost 18% 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 or Fleet  branches),  which  grew  22.7%.  This
reflects good  automobile  demand  industry-wide,  as well as continued  greater
emphasis on this product line in the bank's Southern Region.

      Due in part to a 25 BP  increase  in the  average  prime  rate and  higher
yielding acquired Fleet loans, the average loan yield for the quarter just ended
is 17 BP higher than a year ago.





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 .33% as of
September  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 .63%  remains  better  than the
company's  internal goal of less than .75%.  Nonaccruing  loans fell $133,000 or
6.5% as a result of a drop in  commercial  loan  non-accruals,  which was almost
matched by higher  commercial loan  delinquencies.  The balance of the change in
loans  delinquent  90 days or more  reflects  softening in consumer  installment
loans.

      The ratio of non performing  consumer loans to consumer loans  outstanding
increased 23 BP over the last 12 months to .48% at September 30, 1997.  The same
ratio for time and demand loans fell 25 BPs to .62% and for mortgages  increased
1 BP to .47%.

      Loans 30 days or more past due plus  nonaccruing  loans have  increased $6
million or 72.4% during the last year,  largely due to an increase in delinquent
installment  loans.  A good  portion  of this  latter  increase  relates  to two
problems  (one  lender  and one  dealer  relationship),  both  which  have  been
resolved. The balance of the consumer increase reflects a generalized trend. The
rise in commercial loan delinquency is in the 30-89 day category.

coverage of the  provision  over net  charge-offs  as well as the  addition of a
total $3.5 million valuation allowance resulting from intensive credit review of
the loans purchased from Key and Fleet.

 * May not foot due to rounding

      Average  deposits  increased  $327.9 million or 31.9% for the 1997 quarter
just ended  compared to the same 1996 quarter.  At purchase  date,  acquired Key
deposits  totaled $149.9 million,  while Fleet deposits  totaled $159.1 million.
Deposits were acquired in all major  categories.  Forty-five  percent of the Key
and Fleet deposits were classified as CDs (including  IRAs),  slightly less than
the core bank mix.

      Due largely to the overall  growing mix of higher cost time deposits (upon
which the rate is also  increasing)  and an average  Fed Funds rate moving up 26
BP's from third  quarter 1996 to third  quarter 1997 (which  influences  certain
deposit pricing), the average total deposit rate moved up 18 BP's.

 * May not foot due to rounding

      Borrowings  for third quarter 1997  averaged  $104.0  million  compared to
$145.0 million for third quarter 1996.  The decrease  resulted from the acquired
deposits  utilized  to pay down a portion of  short-term  borrowings,  partially
offset by the  issuance of $30 million in Trust  Preferred  securities.  Average
loans grew  $188.7  million  (30.8%) in the past  twelve  months  while  average
investments grew $64.0 million (11.2%).




G. Investments and Asset/Liability Management

      The investment portfolio at quarter end comprised 42.0% of earning assets,
down from 48.7% on September 30, 1996,  primarily  because of the planned faster
growth of the loan  portfolio  versus the  investment  portfolio (in part due to
loans acquired in the acquisitions).

      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  decreased  15 BP to 7.33% on  average  for third
quarter  1997 versus 7.48% for third  quarter  1996;  these  yields  exclude the
impact of two Federal Home Loan Bank  dividends  recognized in the third quarter
of 1996  (reflecting a change to accrual  matching of the dividend to the period
in which  it is  earned)  and  $321,000  in third  quarter  1997  bond  discount
accretion  adjustments  on $29.5 million in called bonds.  The downward trend in
yield  reflects  the  impact  of a  flat  Treasury  yield  curve  offering  less
attractive reinvestment opportunities.

      The portfolio  market value  increased  from 100.6% of book value one year
ago to 102.2% of book value as of September  30,  1997.  The average life of the
portfolio  decreased  from  4.8  years on  September  30,  1996 to 3.4  years on
September  30,  1997.  This  decrease was due to the sale of  approximately  $22
million in variable rate, long-term securities.

      As of the most recent quarter end,  50.1% of the investment  portfolio was
classified as available-for-sale (AFS) in accordance with SFAS No. 115, with the
remainder (49.9%) as held-to-maturity. The pretax market value adjustment of the
AFS  portfolio  was a  favorable  $4.2  million as  compared  to $647,000 a year
earlier.
