3. ACQUISITION

On May 1, 2001, FII acquired all of the common stock of BNC, and its
wholly-owned subsidiary bank, Bath National Bank ("BNB"). BNB is a full service
community bank headquartered in Bath, New York, which has 11 branch locations in
Steuben, Yates, Ontario and Schuyler Counties. The Company paid $48.00 per share
in cash for each of the outstanding shares of BNC common stock with an aggregate
purchase price of approximately $62.6 million. The acquisition was accounted for
under the purchase method of accounting, and accordingly, the excess of the
purchase price over the fair value of identifiable assets acquired, less
liabilities assumed, has been recorded as goodwill. Goodwill recognized with
respect to the merger was approximately $37.2 million. Goodwill is being
amortized using the straight-line method over 15-years. In accordance with SFAS
No. 142 (See Note 5), the Company will cease goodwill amortization on January 1,
2001 and will evaluate goodwill for impairment annually thereafter. The results
of operations for BNB are included in the income statement from the date of
acquisition (May 1, 2001) to the end of the period.

The table below presents certain unaudited pro forma information as if the BNC
acquisition, which ocurred in 2001, had been consummated on January 1, 2000.
This proforma information gives effect to certain adjustments, including
accounting adjustments related to fair value adjustments, amortization of
goodwill and related income tax effects. The pro forma information does not
necessarily reflect the results of operations that would have occurred had the
Company acquired BNC on January 1, 2000.

5. NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement, as amended by SFAS No. 138,
requires recognition of derivatives as either assets or liabilities, with the
instruments measured at fair value. The accounting for gains and losses
resulting from changes in fair value of the derivative instrument depends on the
intended use of the derivative and the type of risk being hedged. The Company
adopted SFAS No. 133 on January 1, 2001. The adoption of this statement did not
have a material effect on the Company's financial position or results of
operations.

In June, 2001 the FASB issued SFAS Nos. 141, "Business Combinations" and 142,
"Goodwill and Other Intangible Assets." SFAS No. 141 requires that all business
combinations be accounted for under the purchase method, use of the
pooling-of-interests method is no longer permitted for business combinations
initiated after June 30, 2001. SFAS No. 142 requires that goodwill (including
goodwill reported in prior acquisitions) no longer be amortized to earnings, but
instead be reviewed for impairment annually, with impairment losses charged to
earnings when they occur. The Company is required to adopt SFAS No. 142
effective January 1, 2002. The results of operations for the six months ended
June 30, 2001 include goodwill amortization from the BNC acquisition of
approximately $413,000. The amortization of goodwill will cease effective
January 1, 2002.

FORWARD-LOOKING STATEMENTS

This quarterly report contains certain "forward-looking statements" covered by
the "safe harbor" provisions of the Private Securities Litigation Reform Act of
1995. When used or incorporated by reference in the Company's disclosure
documents, the words "anticipate," "estimate," "expect," "project," "target,"

forward-looking statements are subject to certain risks, uncertainties and
assumptions, including, but not limited to changes in (1) general economic
conditions, (2) the real estate markets, and (3) interest rates. Should one or
more of these risks or uncertainties materialize, or should underlying

speak only as of the date of the document. The Company expressly disclaims any
obligation or undertaking to publicly release any updates or revisions to any

                                       10



The Company's net income for the second quarter of 2001 increased 17% to
$5,185,000 compared to $4,449,000 for the second quarter of 2000. Net income for
the first six months of 2001 increased 14% to $9,990,000 compared to $8,743,000
for the same period in 2000. Diluted earnings per common share increased to
$0.43 for the second quarter of 2001 and to $0.83 for the first six months of
the year compared to $0.37 and $0.73, respectively, for the same periods in
2000. Return on average common equity was 15.66% for the six months ended June
30, 2001 compared to 15.82% for the same period last year.

For the second quarter of 2001 net interest income increased $2,781,000 to
$15,985,000 compared to $13,204,000 for the second quarter of 2000. Net interest
income for the first six months of 2001 was $29,574,000, an increase of
$3,685,000 from $25,889,000 for the first six months of 2000. Total loans at
quarter end were $1,130 million, an increase of $294 million over the same
period last year. BNB accounted for $189 million of the increase with the
additional $105 million reflecting the continuing expansion of both the
commercial and consumer loan portfolios in the Company's existing and contiguous
markets. Net interest margin was 4.62% for the second quarter of 2001 and 4.63%
for the first six months of 2001. That compares to 4.95% and 4.97% for the same
periods last year. The decrease in net interest margin is consistent with
management's expectations in the falling interest rate environment and is
reflective of incremental asset growth at lower margins. However, the Company
has achieved strong growth in net interest income given a marketplace
environment of increasing price competitiveness and rapidly declining market
interest rates.

Noninterest income increased 50% in the second quarter of 2001 to $3,452,000
from $2,303,000 for the same period in 2000. While the addition of BNB
contributed to the increase, the significant growth reflects the benefit of the
continuing growth in deposits and the related service fees, as well as the
expansion of our investment brokerage and trust businesses. In addition, gains
realized principally from the call of securities totaled $173,000 in the second
quarter of 2001 and $358,000 for the first six months of 2001.

Noninterest expense for the second quarter of 2001 was $10,409,000 compared to
$7,375,000 for the second quarter of 2000. For the six months ended June 30,
2001, noninterest expense was $18,653,000, an increase from $14,582,000 for the
same period in 2000. The increases reflect the impact of BNB together with
increased staffing and technology resources necessary to support continued
expansion of our existing product lines and delivery channels. Nonetheless the
efficiency ratio for the second quarter of 2001 remained strong at 48.5%
compared to 47.2% for the first quarter of 2001 and 44.7% for the second quarter
of 2000.

The provision for loan losses for the second quarter of 2001 was $1,026,000,
compared to $1,172,000 for the same period in 2000. For the first six months of
2001 the provision was $1,837,000 compared to $2,007,000 for the same period in
2000. The increase in nonperforming loans to $10,705,000 at June 30, 2001
compared to $7,927,000 at June 30, 2000 directly results from the addition of
$2,993,000 in nonperforming loans at BNB. The Company's ratio of nonperforming
loans to total loans was .95% at both June 30, 2001 and June 30, 2000. However,
the ratio of the allowance for loan losses to nonperforming loans increased to
166.41% at June 30, 2001, up from 158.72% a year ago. The ratio of the allowance
for loan losses to total loans also improved to 1.58% at June 30, 2001, compared
to 1.50% a year ago.

At June 30, 2001 the Company had total assets of $1,715 million, an increase of
$511 million ($296 million from the BNB acquisition) from $1,204 million at June
30, 2000. Total deposits were $1,382 million at the recent quarter-end, compared
with $989 million a year earlier with the BNB acquisition accounting for $231
million of the increase. Total shareholders' equity increased 16% to $141
million at June 30, 2001 from $122 million a year earlier.

The following table presents the extent to which changes in interest rates and
changes in the volume of interest-earning assets and interest-bearing
liabilities have affected the Company's interest income and interest expense
during the periods indicated. Information is provided in each category with
respect to: (1) changes attributable to changes in volume (changes in volume
multiplied by the current year rate); (2) changes attributable to changes in
rate (changes in rate multiplied by the prior year volume); and (3) the net
change. The changes attributable to the combined impact of volume and rate have
been allocated proportionately to the changes due to volume and changes due to
rate.

Item 3: Quantitative and Qualitative Disclosures about Market Risk

The Company realizes income principally from the differential or spread between
the interest earned on loans, investments and other interest-earning assets and
the interest paid on deposits and borrowings. Loan volumes and yields, as well
as the volume of and rates on investments, deposits and borrowings, are affected
by market interest rates. Additionally, because of the terms and conditions of
many of the Company's loan documents and deposit accounts, a change in interest
rates could also affect the projected maturities of the loan portfolio and/or
the deposit base, which could alter the Company's sensitivity to future changes
in interest rates. Accordingly, management considers interest rate risk to be
the Company's most significant market risk.

Interest rate risk management focuses on maintaining consistent growth in net
interest income within Board approved policy limits while taking into
consideration, among other factors, the Company's overall credit, operating
income, operating cost, and capital profile. The Company's Asset/Liability
Committee (ALCO), which includes senior management and reports to the Board of
Directors, monitors and manages interest rate risk to maintain an acceptable
level of change to net interest income as a result of changes in interest rates.

Management of the Company's interest rate risk requires the selection of
appropriate techniques and instruments to be utilized after considering the
benefits, costs and risks associated with available alternatives. Since the
Company does not utilize derivative instruments, management's techniques usually
consider one or more of the following: (1) interest rates offered on products,
(2) maturity terms offered on products, (3) types of products offered, and (4)
products available to the Company in the wholesale market such as advances from
the FHLB.

The Company uses a net interest income and economic value of equity model as one
method to identify and manage its interest rate risk profile. The model is based
on expected cash flows and repricing characteristics for all financial
instruments and incorporates market-based assumptions regarding the impact of
changing interest rates on these financial instruments. Assumptions based on the
historical behavior of deposit rates and balances in relation to changes in
interest rates are also incorporated into the model. These assumptions are
inherently uncertain and, as a result, the model cannot precisely measure net
interest income or precisely predict the impact of fluctuations in interest
rates on net interest income. Actual results will differ from simulated results
due to timing, magnitude, and frequency of interest rate changes as well as
changes in market conditions and management strategies. The Company has
experienced no significant changes in market risk due to changes in interest
rates since the Company's Annual Report on Form 10-K as of December 31, 2000
dated March 29, 2001 as filed with the Securities and Exchange Commission.

Management also uses the static gap analysis to identify and manage the
Company's interest rate risk profile. Interest sensitivity gap ("gap") analysis
measures the difference between the assets and liabilities repricing or maturing
within specific time periods.
