6. NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement requires the Company to
recognize all 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. SFAS No. 133's effective
date was deferred in June 1999 by FASB's issuance of SFAS No. 137, "Accounting
for Derivative Instruments and Hedging Activities - Deferral of the Effective
Date of FASB Statement No. 133" and is now effective for fiscal years beginning
after June 15, 2000, although earlier adoption is permitted. Based upon current
activities, the adoption of this statement will not have an effect on the
Company's financial position or results of operations. SFAS No. 133 also permits
certain reclassification of securities to the available for sale category from
the held to maturity category.

Primarily as a result of the factors described below, the Company's net income
for the second quarter of 1999 increased 11.5% to $3,885,000 compared to
$3,483,000 for the second quarter of 1998. Net income for the first six months
of 1999 increased 11.1% to $7,631,000 compared to $6,869,000 for the same period
in 1998. Diluted earnings per share rose 12.9% to $.35 for the second quarter of
1999 from $.31 in the second quarter of 1998. For the first six months of 1999
diluted earnings per share of $.69 were 11.3% higher than the $.62 for the same
period in 1998. Return on average common equity was an annualized 17.13% for the
six months ended June 30,1999 compared to 17.19% in the same period in 1998.

Net interest income increased 10.3% to $11,412,000 for the second quarter of
1999 compared to $10,346,000 for the second quarter of 1998. The increase
resulted from 12.7% growth in average earning assets more than offsetting a 9
basis point decline in net interest margin. Average earning assets for the
second quarter of 1999 increased to $968.2 million from $859.3 million in the
second quarter of 1998. Net interest margin for the second quarter of 1999 was
4.95% compared to 5.04% for the same period in 1998. Net interest income for the
first six months of 1999 was $22,228,000, an increase of 8.1% from $20,563,000
for the first six months of 1998. Net interest margin of 4.95% for the first six
months of 1999 compares to 5.12% for the same period in 1998. The margin
compression is attributed to heightened competition for loan assets.

Noninterest income of $1,900,000 for the second quarter of 1999 increased 23.3%
from $1,541,000 for the same period in 1998. The increase is principally from an
increase in deposit service charges together with a $74,000 increase in
investment security gains. Noninterest income for the first six months of 1999
increased 28.8% to $3,725,000 compared to $2,891,000 for the same period last
year.

Noninterest expense for the second quarter of 1999 was up 14.7% to $6,761,000
from $5,897,000 for the second quarter of 1998. The Company's efficiency ratio
for the second quarter of 1999 was 48.59% compared to 47.57% for the same period
a year ago. For the six months ended June 30,1999 noninterest expense increased
13.0% to $13,082,000 from $11,575,000 for the same period in 1998. The increases
in both periods are largely the result of increases in staffing levels from
expanding lending activities, technological expenditures associated with
expanding the Company's product line and distribution channels and the opening
of a new branch office in a contiguous market.

Provision for loan losses for the second quarter of 1999 was down 7.3% to
$531,000 from $573,000 for the same period a year ago. For the first six months
of 1999 the provision was $1,056,000, down 7.9% from $1,146,000 for the same
period a year ago. Nonperforming assets at June 30, 1999 were $8.7 million, a
decrease of $1.3 million from $10.0 million at June 30,1998. When including the
impact of government guarantees, nonperforming assets at June 30, 1999 were $7.5
million, a decrease of $900,000 from $8.4 million at June 30, 1998.

Income tax expense increased to $2.1 million for the Second Quarter 1999 from
$1.9 million for the Second Quarter 1998. The effective tax rate for the Second
Quarter 1999 was 35.5%, compared to 35.7% for the Second Quarter 1998.

At June 30, 1999 the Company had total assets of $1.03 billion, an increase of
5.5% from $976.2 million at December 31, 1998. Loans increased 7.1% to $701.8
million at June 30, 1999 from $655.4 million at December 31, 1998. Total
deposits were $869.8 million at the recent quarter-end, compared with $850.5
million at December 31, 1998. Total shareholders' equity increased 17.4% to
$113.4 million at June 30, 1999, from $96.6 million at December 31, 1998. During
the second quarter of 1999 the Company completed an initial public offering of
1,103,133 shares of common stock that raised $13.7 million in net capital. Book
value per common share at June 30, 1999 was $8.67, an increase of 9.2% from
$7.94 at December 31, 1998. Tangible book value per common share was $8.35 at
June 30, 1999, an increase of 10.7% from $7.54 at December 31, 1998.

(1)   Amounts shown are amortized cost. In order to make pre-tax income and
      resultant yields on tax-exempt securities 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%.

YEAR 2000 COMPLIANCE

General

The Year 2000 risk involves computer programs and computer software that are not
able to perform into the Year 2000 without interruption. If computer systems do
not correctly recognize the date change from December 31, 1999 to January 1,
2000, computer applications that rely on the date field could fail or create
erroneous results. Such


                                       19


erroneous results could affect interest, payment, or due dates or cause a
temporary inability to process transactions, send invoices or engage in similar
normal business activities. If these issues are not addressed by us, our
suppliers and our borrowers, there could be a material adverse impact on our
financial condition or results of operations.

State Of Readiness

We formally initiated our Year 2000 project plan in September 1997 to ensure
that our operational and financial systems would not be adversely affected by
Year 2000 problems. We have formed a Year 2000 project team and our Board of
Directors and management, as well as those of our subsidiary banks, are
supporting all compliance efforts and allocating the necessary resources to
ensure completion. An inventory of all systems and products (including both
information technology and non-informational technology systems) that could be
affected by the Year 2000 date change has been developed, verified and
categorized as to its importance to us. Also, an assessment of all major
information technology and critical non-information technology systems has been
completed. This assessment involved inputting test data which simulates the Year
2000 date change into such information technology systems and reviewing the
system output for accuracy. Our assessment of critical non-information
technology systems involved reviewing such systems to determine whether they
were date dependent. Based on such assessment, we believe that none of our
critical non-information technology systems is date dependent.

The software for our systems is provided through software vendors. We have
contacted all of our third party vendors and software providers and required
them to demonstrate and represent that their products are or will be Year 2000
compliant. The recommended version upgrades were completed and vendors that were
unable to demonstrate that they were Year 2000 compliant were replaced. We have
in place an ongoing program of testing compliance with these representations and
warranties. Our core banking software provider, which supports substantially all
of our data processing functions, has warranted in writing that its software is
Year 2000 compliant and complies with applicable regulatory guidelines. We have
performed tests to verify this assertion. The results were validated and
accepted with no exceptions noted. We believe we would have recourse against
these vendors and software providers for actual damages incurred by us in the
event the vendors or software providers breach this warranty. In addition, our
compliance and that of our banks with Year 2000 directives and guidelines issued
by the Federal Financial Institutions Examination Council ("FFIEC") and other
bank regulatory agencies has been reviewed by the FDIC, the Federal Reserve
Board, the Office of Comptroller of the Currency and the New York State Banking
Department in 1998 and 1999.

We have completed the following phases of our Year 2000 plan:
Identifying Year 2000 issues;
Assessing the impact of Year 2000 issues on our mission critical systems;
Upgrading our systems as necessary to resolve those Year 2000 issues which have
been identified; and
Testing and implementing those systems that have been upgraded.

Costs of Compliance

We do not expect that the costs of bringing our systems into Year 2000
compliance will have a material adverse effect on our financial condition,
results of operations or liquidity. We have budgeted $250,000 to address Year
2000 issues and approximately $129,000 of the budget has been expended through
June 30, 1999. The largest potential risk to us concerning Year 2000 is the
malfunction of our data processing system. In the event our data processing
system does not function properly, we are prepared to perform critical functions
manually. We believe we are in compliance with regulatory guidelines regarding
Year 2000 compliance, including the timetable for achieving compliance.

Risks Related to Third Parties

We cannot accurately gauge the impact of Year 2000 noncompliance by third
parties with which our banks and we transact business. We have identified our
largest dollar deposit customers (which are aggregate deposits over $250,000)
and our largest commercial/agricultural loan customers (which are loans over
$100,000). Based on information available to us, we conducted a preliminary
evaluation to determine which of


                                       20


those customers are likely to be affected by Year 2000 issues. We then surveyed
those customers deemed at risk to determine their readiness with respect to Year
2000 issues, including (1) their awareness of Year 2000 issues, (2) plans to
address such issues and (3) progress with respect to such plans. The survey
included 100% of all depositors with average balances of $250,000 or greater,
which approximately 30% of our total dollar deposit base. The survey also
included approximately 90% of our commercial/agricultural borrowers of $100,000
or more, which is approximately 50% of our total dollar loan base. The responses
to these surveys were due by December 31, 1998. We are continuing to follow up
with those borrowers who have not responded to the surveys. We will continue to
review such responses as they are returned and will encourage customers to
resolve any identified problems. To the extent a problem is identified, we
intend to monitor the customer's progress in resolving such problem. In the
event that Year 2000 noncompliance adversely affects a borrower, we may be
required to charge-off the loan to that borrower. In the event that Year 2000
noncompliance causes a depositor to withdraw funds, we plan to maintain
additional cash on hand. With respect to our borrowers, we include in our loan
documents a Year 2000 disclosure form and an addendum to the loan agreements in
which the borrower represents and warrants its Year 2000 compliance to the bank.

Contingency Plans

We are finalizing our contingency planning with respect to the Year 2000 date
change and believe that if our own systems should fail, we could convert to a
manual entry system for a period of up to three months without significant
losses. We believe that any mission critical systems could be recovered and
operating within seven days. In the event that the Federal Reserve is unable to
handle electronic funds transfers and check clearing, we do not expect the
impact to be material to our financial condition or results of operations as
long as we are able to utilize an alternative electronic funds transfer and
clearing source. As part of our contingency planning, we have reviewed our loan
customer base and the potential impact on capital of Year 2000 noncompliance.
Based upon such review, using what we consider to be a reasonably likely worst
case scenario, we have assumed that certain of our commercial borrowers whose
businesses are most likely to be affected by Year 2000 noncompliance would be
unable to repay their loans, resulting in charge-off's of loan amounts in excess
of collateral values. If this occurs, we believe that it is unlikely that our
exposure would exceed $280,000, although we cannot assure you of this amount and
the amount could be higher. We do not believe that this amount is material
enough for us to adjust our current methodology for making provisions to the
allowance for loan losses. In addition, we plan to maintain additional cash on
hand to meet any unusual deposit withdrawal activity.

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-earnings 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)


                                       21


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.

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.
