     with instructions for Form 10-Q and, therefore, do not include information
     or footnotes necessary for a complete presentation of financial position,
     results of operations, and cash flows in conformity with accounting
     principles generally accepted in the United States of America. However, in
     the opinion of management, all adjustments consisting of only normal
     recurring adjustments or accruals which are necessary for a fair
     presentation of the financial statements have been made at and for the
     three and nine months ended September 30, 2002 and 2001. The results of
     operations for the three and nine month periods ended September 30, 2002
     are not necessarily indicative of the results which may be expected for an
     entire fiscal year or other interim periods.

     The unaudited consolidated financial statements should be read in
     conjunction with the Company's 2001 Annual Report on Form 10-K. Amounts in
     the prior periods' consolidated financial statements are reclassified when
     necessary to conform to the current periods' presentation. All intercompany
     accounts and transactions have been eliminated in consolidation.

(3)  NET INCOME PER SHARE

     Basic net income per common share for the three-month and nine-month
     periods ended September 30, 2002 and 2001 was computed by dividing net
     income by the weighted average number of total common shares outstanding
     during the period, excluding unallocated ESOP shares and deferred stock
     compensation shares. Diluted net income per common share reflects the
     effects of incremental common shares (computed using the treasury stock
     method) that would be issuable upon exercise of dilutive stock options and
     unearned stock compensation.

(4)  DIVIDENDS

     The Company declared a regular cash dividend of $.06 per share for the
     quarter ended June 30, 2002 on July 15, 2002, payable August 12, 2002 to
     stockholders of record July 29, 2002.

(5)  RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the Financial Accounting Standards Board (FASB) issued SFAS
     No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other
     Intangible Assets. SFAS No. 141 requires that the purchase method of
     accounting be used for all business combinations initiated after June 30,
     2001. SFAS No. 141 also specifies criteria intangible assets acquired in a
     purchase method business combination must meet to be recognized and
     reported apart from goodwill. SFAS No. 142 requires acquired intangible
     assets (other than goodwill) to be amortized over their useful economic
     life, while goodwill and any acquired intangible assets with an indefinite
     useful economic life would not be amortized, but would be reviewed for
     impairment on an annual basis based on guidelines specified in SFAS No.
     142.

     The adoption of SFAS Nos. 141 and 142 did not materially affect the
     Company's financial condition and results of operations. The Company
     adopted SFAS No. 141 on July 1, 2001 and SFAS No. 142 on January 1, 2002.

COMPARISON OF FINANCIAL CONDITION AT SEPTEMBER 30, 2002 AND DECEMBER 31, 2001

Total assets as of September 30, 2002 were $386.7 million, an increase of $43.3
million or 12.6% from December 31, 2001. The increase was due primarily to a
$20.9 million or 11.6% increase in net loans, an increase of $4.4 million or
3.3% in securities available for sale, and an increase of $18.6 million in
securities held to maturity. Commercial real estate and business loans increased
by $21.2 million. In addition, home equity loans increased by $5.0 million and
other consumer loans increased by $3.0 million, while residential mortgage loans
decreased by $8.0 million. The increase in securities available for sale is a
result of purchases of $108.6 million, partially offset by amortizations and
prepayments of $32.9 million and sales of $74.1 million. The increase of $18.6
million in securities held to maturity represents securities purchased in
connection with a leverage strategy implemented to enhance net interest income.

The growth in assets during the first nine months of 2002 was funded in part by
a $39.0 million or 16.8% increase in total deposits. Savings deposits increased
by $4.7 million or 7.9%, demand deposits increased $6.6 million or 23.0%, and
certificate of deposits increased $17.7 million or 12.4%. In addition, the
Company originated $10.0 million in brokered certificates of deposit during the
second quarter of 2002. Advances from the Federal Home Loan Bank of New York
("FHLB") increased by $3.0 million or 4.2% during the first nine months of 2002,
as funding needs exceeded retail deposit growth.

Stockholders' equity totaled $38.5 million as of September 30, 2002, an increase
of $1.8 million from December 31, 2001. The increase in stockholders' equity
resulted from net income of $2.1 million, and an increase of $1.6 million in the
market value of securities available for sale, net of related deferred



                                      -10-
<PAGE>

income taxes, partially offset by dividend distributions of $548,000, and
treasury shares purchased in the amount of $1.9 million at an average cost of
$10.91.


COMPARISON OF OPERATING RESULTS FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2002
AND 2001

GENERAL

Net income for the quarter ended September 30, 2002 amounted to $748,000 or
$0.24 per diluted share, compared to net income of $506,000, or $0.16 per
diluted share for the quarter ended September 30, 2001. The increase in net
income is primarily attributable to an increase of $483,000 in net interest
income, as well as an increase in noninterest income of $184,000. This was
partially offset by an increase of $260,000 in noninterest expenses, an increase
in provision for loan losses of $40,000 and an increase of $125,000 in income
tax expense.

NET INTEREST INCOME

Net interest income is determined by our interest rate spread (i.e., the
difference between yields earned on our interest-earning assets and rates paid
on our interest-bearing liabilities) and the relative amounts of our
interest-earning assets and interest-bearing liabilities. Net interest income
amounted to $2.9 million for the three month period ended September 30, 2002, an
increase of $483,000 from the same period last year. The average interest rate
spread for the three-month period ended September 30, 2002 was 2.96% versus
2.63% during the same period in 2001. The average yield on interest-earning
assets decreased 68 basis points from 7.10% to 6.42%, while the average cost of
interest-bearing liabilities decreased 101 basis points from 4.47% to 3.46%.

INTEREST INCOME

Total interest income for the three-month period ended September 30, 2002
amounted to $5.9 million, relatively unchanged from the same period in 2001. The
average yield on earning assets decreased to 6.42% during the three months ended
September 30, 2002 compared to 7.10% in the same period of 2001. Interest income
on loans for the three months ended September 30, 2002 amounted to $3.7 million,
an increase of $81,000 from the same period in 2001. Total loans increased by
$18.9 million to an average outstanding loan balance of $200.8 million for the
three months ended September 30, 2002, offset by a decrease in the average yield
to 7.30% from 7.88% during the same period last year. Interest income on
securities for the three months ended September 30, 2002 amounted to $2.2
million, a decrease of $62,000 from the same period last year. Changes in
interest income on securities resulted from an increase in the average
outstanding securities balance (at amortized cost) of $17.1 million to $162.1
million, offset by a decrease in the yield on the portfolio, as the average
yield decreased 80 basis points to 5.32%.

INTEREST EXPENSE

Total interest expense for the three months ended September 30, 2002 was $3.0
million, a decrease of $462,000 from the same period in 2001. During the third
quarter of 2002, interest expense on deposits amounted to $2.0 million while
interest expense on borrowed funds amounted to $971,000. Interest expense on
deposits decreased $411,000 or 17.0% as average deposits increased $35.9 million
to $269.8 million and the average cost of deposits decreased 115 basis points to
2.95%. The average cost of borrowings decreased 30 basis points to 5.36% from
5.66% a year ago, while average outstanding borrowings remained relatively flat
at $71.8 million.

PROVISION FOR LOAN LOSSES

The provision for loan losses amounted to $130,000 for the three months ended
September 30, 2002, an increase of $40,000 from the same period last year. This
increase reflects management's consideration of qualitative factors, including,
but not limited to, the substantial growth in commercial real estate and
business loans. The allowance for loan losses amounted to $1.9 million as of
September 30, 2002 or 0.91% of total loans outstanding and 616% of
non-performing loans. Non-performing loans decreased from $362,000 as of
December 31, 2001 to $301,000 as of September 30, 2002. The decrease in
non-



                                      -11-
<PAGE>
performing loans primarily relates to a charge off of $76,000 on one
commercial relationship. The ratio of non-performing assets to total assets was
0.10% at September 30, 2002 as compared to 0.20% at December 31, 2001. Net
recoveries of $8,500 were recognized during the third quarter of 2002, as
compared to net charge-offs of $102,000 for the same period last year.

Management reviews the adequacy of the allowance for loan losses quarterly
through an asset classification and review process and an analysis of the level
of loan delinquencies and general market and economic conditions. To the best of
Management's knowledge, the allowance for loan losses includes all known and
inherent losses at each reporting date that are both probable and reasonable to
estimate. However, there can be no assurance that the allowance for loan losses
will be adequate to cover all losses that may in fact be realized in the future
or that additional provisions for loan losses will not be required.

NONINTEREST  INCOME

Noninterest income, consisting primarily of service charges on deposit accounts,
loan servicing fees, increases in the value of bank owned life insurance, and
gains and losses on loans and securities sold, was $789,000 for the three months
ended September 30, 2002, an increase of $184,000 or 30.4% compared to the third
quarter of 2001. Service charges and other fee income was $451,000 for the three
months ended September 30, 2002, an increase of $104,000 over the same period in
2001. This improvement is primarily attributable to an increase of $84,000 in
service charges on deposit accounts and $22,000 in loan prepayment penalties.
Net gains on the sale of securities were $151,000, an increase of $60,000 from
the same period last year. This increase resulted primarily from sales of
securities with longer average lives, as we restructured a portion of the
securities portfolio to achieve an overall shorter duration of the portfolio.

NONINTEREST EXPENSE

Noninterest expense amounted to $2.5 million for the three months ended
September 30, 2002, an increase of $260,000 or 11.9% from the same period last
year. An increase of $265,000 in salaries and employee benefits expense was
primarily the result of annual salary increases and the cost of stock-based
benefit plans. Office occupancy and equipment expense remained unchanged from
the prior year. Professional fees decreased $6,000 or 4.7% from the same period
last year, primarily due to the decision to discontinue outsourcing certain
information technology functions. Marketing and advertising expenses decreased
$21,000 or 25% from the same period last year, primarily due to expenses
relating to a new product line for small business, introduced at this time last
year. Other noninterest expense, which in part includes postage, office
supplies, telephone charges, director's fees, insurance, and third party check
processing, increased $22,000 or 5.0% from the same period last year.

INCOME TAXES

Income tax expense for the three months ended September 30, 2002 was $348,000 on
income before tax of $1.1 million, reflecting an effective tax rate of 31.8%.
For the same period in 2001, the effective rate was 30.6%. We have managed our
effective tax rate through our purchase of bank owned life insurance, which is a
tax-advantaged means of financing employee benefits, the formation of a real
estate investment trust in September 2001, as well as our investment in
municipal bonds, which totaled $2.4 million at September 30, 2002.

COMPARISON OF OPERATING RESULTS FOR THE NINE MONTHS ENDED SEPTEMBER 30, 2002
AND 2001

GENERAL

Net income for the nine months ended September 30, 2002 amounted to $2.1 million
or $0.67 per diluted share, compared to net income of $1.3 million, or $0.40 per
diluted share for the nine months ended September 30, 2001. The increase in net
income is primarily attributable to an increase of $1.7 million in net interest
income and an increase of $348,000 in noninterest income. This was partially
offset by an


                                      -12-
<PAGE>

increase of $641,000 in noninterest expenses, an increase of $245,000 in loan
loss provisions, and an increase of $359,000 in income tax expense.

NET INTEREST INCOME

Net interest income is determined by our interest rate spread (i.e., the
difference between yields earned on our interest-earning assets and rates paid
on our interest-bearing liabilities) and the relative amounts of our
interest-earning assets and interest-bearing liabilities. Net interest income
amounted to $8.5 million for the nine-month period ended September 30, 2002, an
increase of $1.7 million from the same period last year. The average interest
rate spread for the nine-month period ended September 30, 2002 was 3.07% versus
2.47% during the same period in 2001. Based on the maturity and repricing
characteristics of the Company's balance sheet, during the first nine months of
the year 2002 when interest rates were falling, liabilities repriced at a faster
rate than assets. The average yield on interest-earning assets decreased 62
basis points from 7.30% to 6.68%, while the average cost of interest-bearing
liabilities decreased 123 basis points from 4.83% to 3.60%.

INTEREST INCOME

Total interest income for the nine-month period ended September 30, 2002
amounted to $17.3 million, a decrease of $364,000 from the same period in 2001.
The average yield on earning assets decreased to 6.68% during the nine months
ended September 30, 2002 compared to 7.30% in the same period of 2001. Interest
income on loans for the nine months ended September 30, 2002 amounted to $10.8
million, relatively unchanged from the same period in 2001. Total loans
increased to an average outstanding loan balance of $192.0 million for the nine
months ended September 30, 2002, offset by a decrease in the average yield to
7.49% from 8.05% during the same period last year. Interest income on securities
for the nine months ended September 30, 2002 amounted to $6.6 million, a
decrease of $362,000 from the same period last year. This decrease was
attributed to an increase in the average outstanding securities balance (at
amortized cost), which increased by $9.5 million to $154.5 million, offset by a
decrease in the yield on the portfolio, as the average yield decreased 70 basis
points to 5.69%.

INTEREST EXPENSE

Total interest expense for the nine months ended September 30, 2002 was $8.8
million, a decrease of $2.1 million from the same period in 2001. For the first
nine months of 2002, interest expense on deposits amounted to $5.9 million while
interest expense on borrowed funds amounted to $2.9 million. Interest expense on
deposits decreased $2.0 million as average deposits increased $20.4 million to
$253.6 million while the average cost of deposits decreased 143 basis points to
3.10%. Interest expense on borrowings decreased $66,000 from the same period
last year. The average cost of borrowings decreased 53 basis points to 5.32%
from 5.85% a year ago, while the average outstanding borrowings increased $5.2
million to $73.3 million.

PROVISION FOR LOAN LOSSES

The provision for loan losses amounted to $470,000 for the nine months ended
September 30, 2002, an increase of $245,000 from the same period last year. This
increase reflects management's consideration of qualitative factors, including,
but not limited to, the substantial growth in commercial real estate and
business loans. The allowance for loan losses amounted to $1.9 million as of
September 30, 2002 or 0.91% of total loans outstanding and 616% of
non-performing loans. Non-performing loans decreased from $362,000 as of
December 31, 2001 to $301,000 as of September 30, 2002. The decrease in
non-performing loans is primarily the result of a charge off of one commercial
relationship. The ratio of non-performing assets to total assets was 0.10% at
September 30, 2002 as compared to 0.20% at December 31, 2001. Net charge-offs
during the first nine months of 2002 were $181,000, as compared to $153,000 for
the same period last year.

Management reviews the adequacy of the allowance for loan losses quarterly
through an asset classification and review process and an analysis of the level
of loan delinquencies and general market and economic conditions. To the best of
Management's knowledge, the allowance for loan losses

                                      -13-

includes all known and inherent losses at each reporting date that are both
probable and reasonable to estimate. However, there can be no assurance that the
allowance for loan losses will be adequate to cover all losses that may in fact
be realized in the future or that additional provisions for loan losses will not
be required.

NONINTEREST INCOME

Noninterest income, consisting primarily of service charges on deposit accounts,
loan servicing fees, income from the sale of annuities and mutual funds,
increases in the value of bank owned life insurance, and gains and losses on
loans and securities sold, was $2.2 million for the nine months ended September
30, 2002, an increase of $348,000 or 18.9% compared to the same period in 2001.
Service charges and other fee income was $1.3 million for the nine months ended
September 30, 2002, an increase of $299,000 or 29.9% over the same period in
2001. This improvement is primarily attributable to an increase of $237,000 or
32.4% in service charges on deposit accounts, as well as $87,000 in loan
prepayment penalties. Gains on sale of securities decreased $53,000 during the
nine-month period ended September 30, 2002 as compared to the same period last
year as a result of a restructuring of the portfolio during 2001. The increase
of $69,000 in net gains from the sale of loans reflects higher levels of loan
sales during 2002. The increase in the cash value of bank owned life insurance
in the amount of $33,000 can be attributed to the purchase of additional
insurance in March 2001.

NONINTEREST EXPENSE

Noninterest expense amounted to $7.2 million for the nine months ended September
30, 2002, an increase of $641,000 or 9.7% from the same period last year. An
increase of $712,000 in salaries and employee benefits expense was primarily the
result of annual salary increases and the cost of stock-based benefit plans. A
decrease of $30,000 in office occupancy and equipment expense was in part the
result of lower depreciation expense, due to a fully depreciated branch and
related equipment in our Ithaca market. In addition, lower utility costs this
year contributed $14,000 to the reduction in office occupancy expense.
Professional fees decreased $11,000 or 2.8%, due in part to the decision to
discontinue outsourcing certain information technology functions. This decrease
in professional fees is offset by increased legal fees incurred in connection
with a review of certain benefit plans. Marketing expenses increased $23,000 or
8.4% primarily due to expenses relating to a certificate of deposit promotion
targeted at longer term maturities, as well as a renewed home equity loan
campaign. In the second quarter of 2002, we reversed $166,000 of accruals for
environmental remediation relating to a foreclosed dry cleaning and laundry
facility, as the final project costs were less than the budgeted estimates. The
remediation work is completed and we are currently negotiating a contract to
continue monitoring of the property. We have determined that the recorded
liability is currently adequate to cover the anticipated costs of the monitoring
for the new contract period. Other noninterest expense, which in part includes
postage, office supplies, telephone charges, director's fees, insurance, and
third party check processing, increased $111,000 or 8.5% from the same period
last year. This is in part due to increased costs on life insurance policies, as
well as increased costs for NASDAQ filing and investor relations.

INCOME TAXES

Income tax expense for the nine months ended September 30, 2002 was $930,000 on
income before tax of $3.0 million, reflecting an effective tax rate of 30.8%.
For the same period in 2001, the effective rate was 31.0%. The decrease in our
effective tax rate is the result of our purchase of bank owned life insurance,
which is a tax-advantaged means of financing employee benefits, the formation of
a real estate investment trust in September 2001, as well as our investment in
municipal bonds, which totaled $2.4 million at September 30, 2002.

ITEM 3 -- QUANTITATIVE & QUALITATIVE DISCLOSURE ABOUT MARKET RISK


                                      -14-
<PAGE>

Market risk is the risk of loss from adverse changes in market prices and
interest rates. The Company's market risk arises primarily from interest rate
risk inherent in its lending and deposit taking activities. Although the Company
manages other risks, as in credit and liquidity risk, in the normal course of
its business, management considers interest rate risk to be its most significant
market risk and could potentially have the largest material effect on the
Company's financial condition and results of operations. The Company does not
currently have a trading portfolio nor does it use derivatives to manage market
and interest rate risk.

The Company's interest rate risk management is the responsibility of the
Asset/Liability Management Committee (ALCO), which reports to the Board of
Directors. The committee, comprised of senior management, has developed policies
to measure, manage, and monitor interest rate risk. Interest rate risk arises
from a variety of factors, including differences in the timing between the
contractual maturity or repricing of the Company's assets and liabilities. For
example, the Company's net interest income is affected by changes in the level
of market interest rates as the repricing characteristics of its loans and other
assets do not necessarily match those of its deposits, borrowings and capital.

The OTS requires the Company to measure interest rate risk by computing
estimated changes in the net portfolio value ("NPV") of cash flows from assets,
liabilities and off-balance sheet items in the event of a range of assumed
changes in market interest rates. These computations estimate the effect on NPV
of sudden and sustained 100 to 300 basis point increases and decreases in market
interest rates. The Company's board of directors has adopted an interest rate
risk policy which establishes minimum NPV ratios (i.e. the ratio of NPV to the
present value of assets) in the event of 100, 200 and 300 basis point increases
and decreases in market interest rates. The following table sets forth certain
calculations, based on information provided to the Company by the OTS, with
respect to the sensitivity of NPV to changes in market interest rates at June
30, 2002 (date of latest available data):
<TABLE>

     +100             36,936        (4,433)         (11)           9.38           (90) bp
       -              41,370             -            -           10.28             -

</TABLE>


As shown by the table, increases in interest rates are estimated to
significantly decrease our NPV, while decreases in interest rates are estimated
to result in much smaller net changes in our NPV. The table suggests that in the
event of a 200 basis point increase in interest rates, we would experience a
decrease in NPV as a percentage of assets to 7.97% from 10.28%. Net portfolio
values in a falling rate environment of 200 and 300 basis points or more have
not been shown, due to the current interest rate environment of historically low
rates.

The Board of Directors is responsible for reviewing asset liability management
policies. On at least a quarterly basis, the Board reviews interest rate risk
and trends, as well as liquidity and capital ratios and requirements. Management
is responsible for administering the policies and determinations of the Board of
Directors with respect to our asset and liability goals and strategies.
