FINANCIAL INSTITUTIONS. INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE THREE MONTHS ENDED
MARCH 31, 2001 and 2000
(Unaudited)

1. BASIS OF PRESENTATION

Financial Institutions. Inc. (the "Company") is a bank holding company with four
commercial banks subsidiaries that operate in Western and Central New York
State: Wyoming County Bank ("WCB"); The National Bank of Geneva ("NBG"); The
Pavilion State Bank ("PSB"); and, First Tier Bank & Trust ("FTB") (collectively
the "Banks"). The Company is also the parent of The FI Group, Inc. ("FIGI") and
FISI Statutory Trust I ("FISI"). FIGI is a brokerage subsidiary that commenced
operations in March 2000. FISI is a trust formed in February 2001 to accommodate
the private placement of $16.2 million in capital securities with several
institutional investors, with the proceeds utilized to aid funding the
acquisition of Bath National Bank ("BNB") (see Note 6). The capital securities
are identified on the balance sheet as guaranteed preferred beneficial interests
in corporation's junior subordinated debentures. In addition, the capital
securities are an alternative funding vehicle with certain favorable features,
namely, the capital securities qualify as regulatory capital and the related
interest expense is tax-deductible.

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles ("GAAP") for interim
financial information and the instructions for Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by GAAP for complete financial statements. In the opinion of
management, all adjustments necessary for a fair presentation have been included
in the results for the three month periods ended March 31, 2001 and 2000. The
results of operations for the three month period ended March 31, 2001 are not
necessarily indicative of the results which may be expected for the year ending
December 31, 2001 or any other interim period.

The consolidated financial statements include the accounts of the Company, the
Banks, FIGI and FISI. All significant intercompany balances and transactions
have been eliminated in consolidation.

2. EARNINGS PER SHARE

been computed using weighted average common shares outstanding. Diluted earnings
per share reflects the effects, if any, of incremental common shares issuable
upon exercise of dilutive stock options.

Earnings per common share have been computed based on the following:

4. NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board 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.

5. SUBSEQUENT EVENT

On May 1, 2001, the Company acquired all of the outstanding common stock of Bath
National Corporation ("BNC"), and its wholly-owned subsidiary bank, Bath
National Bank ("BNB"). Consolidated assets of BNB were approximately $300
million as of March 31, 2001. 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 will be accounted for using the
purchase method of accounting.

The Company's net income for the first quarter of 2001 increased 11.9% to
$4,805,000 compared to $4,294,000 for the first three months of 2000. Earnings
per common share increased 11.1% to $0.40 for the 2001 quarter from $0.36 in
2000. Return on average common equity was 15.38% for the three months ended
March 31, 2001 compared to 15.69% for the same period last year.

Net interest income increased 7.1% in the first quarter of 2001 to $13,589,000
compared to $12,685,000 for the first three months of 2000. Growth in average
earning assets of 17.3%, in comparison to the same period a year earlier, drove
the increase, as net interest margin decreased to 4.65% from 5.00% for the same
quarter last year. The decrease in net interest margin is reflective of
incremental asset growth at lower margins together with increasing price
competitiveness in a period of declining market interest rates. The growth in
average earning assets is the result of continued expansion of our commercial
loan portfolio as well as our indirect consumer loan portfolio.

Noninterest income increased 34.6% in the first quarter of 2001 to $2,785,000
from $2,069,000 for the same period in 2000. This increase primarily reflects
the benefit of the continuing growth in core deposits and the related service
fees, as well as realized gains on the sale/call of securities of $185,000 and
the sale of residential mortgage loans. In addition, our investment brokerage
fees were $386,000 for the first three months of 2001 an increase of $119,000
from the same period last year.

Noninterest expense for the first quarter of 2001 was up 14.4% to $8,244,000
from $7,207,000 for the prior year period. The increase is primarily due to
additional staffing and technology resources necessary to support continued
expansion of lending activities, product lines and delivery channels.
Nonetheless the efficiency ratio for the first quarter of 2001 remained strong
at 47.2% compared to 45.3% for the same period a year ago.

The provision for loan losses for the first quarter of 2001 was $811,000,
compared to $835,000 for the same period in 2000. The allowance for loan losses
was $14,466,000 at March 31, 2000, an increase of $583,000 from December 31
,2000. Although nonperforming loans increased to $7,681,000 at March 31, 2001
compared to $6,924,000 at March 31, 2000, the ratio of nonperforming loans to
total loans of 0.86% at March 31, 2001 is comparable to 0.88% a year ago, and
the ratio of the allowance for loan losses to nonperforming loans was 188.34% at
March 31, 2001, up from 171.97% a year ago. The ratio of the allowance for loan
losses to total loans also improved to 1.61% at March 31, 2001, compared to
1.51% from a year ago.

At March 31, 2001 the Company had total assets of $1,337.6 million, an increase
of 3.7% from $1,289.3 million at December 31, 2000. Loans increased 1.1% to
$897.2 million at the recent quarter end from $887.1 million at December 31,
2000. Federal funds sold increased to $31.2 million at March 31, 2001 from $0.9
million at December 31, 2000 as a result of overnight investing of funds
appropriated for the acquisition of BNB on May 1, 2001. Funds appropriated for
the BNB acquisition include the private placement of $16.2 million in capital
securities with institutional investors in February 2001. Total deposits were
$1,130.0 million at the recent quarter-end, compared with $1,078.1 million a
quarter earlier. Total shareholders' equity increased 4.3% to $137.3 million at
March 31, 2001 from $131.6 million at December 31 ,2000. Book value per common
share at March 31, 2001 was $10.88, an increase of 5.0% from $10.36 at December
31, 2000.

(1)   Amounts shown are amortized cost for held to maturity securities and fair
      value for available for sale securities. In order for pre-tax income and
      resultant yields on tax-exempt securities to be comparable to those on
      taxable securities and loans, a tax-equivalent adjustment to interest
      earned from tax-exempt securities has been computed using a federal income
      tax rate of 35%.
(2)   Net of deferred loan fees and costs.
(3)   The net interest margin is equal to net interest income divided by average
      interest-earning assets and is presented on an annualized basis.

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.
