Note 1.  Summary of Significant Accounting Policies

         The accompanying unaudited interim consolidated financial statements of
UnionBancorp, Inc. (the "Company") have been prepared in accordance with U.S.
generally accepted accounting principles and with the rules and regulations of
the Securities and Exchange Commission for interim financial reporting.
Accordingly, they do not include all of the information and footnotes required
for complete financial statements. In the opinion of management, all normal and
recurring adjustments which are necessary to fairly present the results for the
interim periods presented have been included. The preparation of financial
statements requires management to make estimates and assumptions that affect the
recorded amounts of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenues and expenses during the reported period. Actual results could differ
from those estimates. For further information with respect to significant
accounting policies followed by the Company in the preparation of its
consolidated financial statements, refer to the Company's Annual Report on Form
10-K for the year ended December 31, 2005. The annualized results of operations
during the three months ended March 31, 2006 are not necessarily indicative of
the results expected for the year ending December 31, 2006. All financial
information is in thousands (000's), except per share data.

Note 2.  Earnings Per Share

         Basic earnings per share for the three months ended March 31, 2006 and
2005 were computed by dividing net income by the weighted average number of
shares outstanding. Diluted earnings per share for the three months ended March
31, 2006 and 2005 were computed by dividing net income by the weighted average
number of shares outstanding, adjusted for the dilutive effect of the stock
options. Computations for basic and diluted earnings per share are provided
below:

         There were approximately 60,000 and 40,000 options outstanding at March
31, 2006 and 2005, respectively, that were not included in the computation of
diluted earnings per share because the options' exercise prices were greater
than the average market price of the common stock and were, therefore,
antidilutive.

Note 5.  Allowance For Loan Losses

         In originating loans, the Company recognizes that credit losses will be
experienced and the risk of loss will vary with, among other things, current
economic conditions; the type of loan being made; the creditworthiness of the
borrower over the term of the loan; and in the case of a collateralized loan,
the quality of the collateral for such loan. The allowance for loan losses
represents the Company's estimate of the allowance necessary to provide for
probable incurred losses in the loan portfolio. In making this determination,
the Company analyzes the ultimate collectibility of the loans in its portfolio,
incorporating feedback provided by internal loan staff, the independent loan
review function and information provided by examinations performed by regulatory
agencies. The Company makes an ongoing evaluation as to the adequacy of the
allowance for loan losses. Transactions in the allowance for loan losses for the
three months ended March 31, 2006 and 2005 are summarized below:

         The intrinsic value for stock options is calculated based on the
exercise price of the underlying awards and the market price of our common stock
as of the reporting date. The intrinsic value of options exercised during the
first quarter of 2006 and 2005 was $173 and $250. The company recorded $34 in
stock compensation expense during the three months ended March 31, 2006 to
salaries and employee benefits.

         The fair value of each stock option granted is estimated using the
Black-Scholes based stock option valuation model. This model requires the input
of subjective assumptions that will usually have a significant impact on the
fair value estimate. Expected volatilities are based on historical volatility of
the Company's stock, and other factors. Expected dividends are based on dividend
trends and the market price of the Company's stock price at grant. The Company
uses historical data to estimate option exercises and employee terminations
within the valuation model. The risk-free rate for periods within the
contractual life of the options is bases on the U. S. Treasury yield curves in
effect at the time of grant. There were no grants during the three months ended
March 31, 2006 and 2005.

         The Company elected to adopt the modified prospective application
method as provided by SFAS 123(R), and, accordingly the Company recorded
compensation costs as the requisite service rendered for the unvested portion of
previously issued awards that remain outstanding at the initial date of adoption
and any awards issued, modified, repurchased, or cancelled after the effective
date of SFAS 123(R).

         Prior to January 1, 2006, the Company accounted for share-based
compensation to employees in accordance with Accounting Principles Board Opinion
(APB) No. 25, "Accounting for Stock Issued to Employees," and related
interpretations. The Company also followed the disclosure requirements of SFAS
123, "Accounting for Stock-Based Compensation". No stock-based compensation was
recognized on employee stock options in the consolidated statement of income
before January 1, 2006. Accordingly, financial statement amounts for the prior
periods presented in this Form 10-Q have not been restated to reflect the fair
value method of expensing share-based compensation.

         SFAS 123R requires the recognition of stock based compensation for the
number of awards that are ultimately expected to vest. As a result, recognized
stock option compensation expense was reduced for estimated forfeitures prior to
vesting primarily based on historical annual forfeiture rates of approximately
three percent. Estimated forfeitures will be reassessed in subsequent periods
and may change based on new facts and circumstances. Prior to January 1, 2006,
actual forfeitures were accounted for as they occurred for purposes of required
pro forma stock compensation disclosures.

         Unrecognized stock option compensation expense related to unvested
awards (net of estimated forfeitures) for the remainder of 2006 and beyond is
estimated as follows:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
(In Thousands, Except Per Share Data)
--------------------------------------------------------------------------------
         The following discussion provides an analysis of the Company's results
of operations and financial condition for the three months ended March 31, 2006
as compared to the same period in 2005. Management's discussion and analysis
(MD&A) should be read in conjunction with the consolidated financial statements
and accompanying notes presented elsewhere in this report as well as the
Company's 2005 Annual Report on Form 10-K. Annualized results of operations
during the three months ended March 31, 2006 are not necessarily indicative of
results to be expected for the full year of 2006. Unless otherwise stated, all
earnings per share data included in this section and throughout the remainder of
this discussion are presented on a diluted basis. All financial information is
in thousands (000's), except per share data.

Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995

         This report contains certain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Act of 1934 as amended. The Company intends such
forward-looking statements to be covered by the safe harbor provisions for
forward-looking statements contained in the Private Securities Litigation Reform
Act of 1995 and is including this statement for purposes of these safe harbor
provisions. Forward-looking statements, which are based on certain assumptions
and describe future plans, strategies, and expectations of the Company, are
generally identified by the use of words such as "believe," "expect," "intend,"
"anticipate," "estimate," "project," "planned" or "potential" or similar
expressions. The Company's ability to predict results, or the actual effect of
future plans or strategies, is inherently uncertain. Factors which could have a
material adverse effect on the operations and future prospects of the Company
and the subsidiaries include, but are not limited to, changes in: interest
rates; general economic conditions; legislative/regulatory changes; monetary and
fiscal policies of the U.S. government, including policies of the U.S. Treasury
and the Federal Reserve Board; the quality and composition of the loan or
securities portfolios; demand for loan products; deposit flows; competition;
demand for financial services in the Company's market areas; the Company's
implementation of new technologies; the Company's ability to develop and
maintain secure and reliable electronic systems; and accounting principles,
policies, and guidelines. These risks and uncertainties should be considered in
evaluating forward-looking statements and undue reliance should not be placed on
such statements.

Critical Accounting Policies and Estimates

         The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. By their nature, changes in these assumptions and estimates
could significantly affect the Company's financial position or results of
operations. Actual results could differ from those estimates. Discussed below
are those critical accounting policies that are of particular significance to
the Company.

         Allowance for Loan Losses: The allowance for loan losses is a valuation
allowance for probable incurred credit losses, increased by the provision for
loan losses and decreased by charge-offs less recoveries. Management estimates
the allowance balance required based on past loan loss experience, the nature
and volume of the portfolio, information about specific borrower situations and
estimated collateral values, current economic conditions, and other factors.
Allocations of the allowance may be made for specific loans, but the entire
allowance is available for any loan that, in management's judgment, should be
charged off. Loan losses are charged against the allowance when management
believes that the uncollectibility of a loan balance is confirmed.

General

         UnionBancorp, Inc. is a bank holding company organized under the laws
of the state of Delaware. The Company derives most of its revenues and income
from the operations of its bank subsidiary, UnionBank (the "Bank"), but also
derives revenue from its Financial Services Division. The Company provides a
full range of services to individual and corporate customers located in the
north central and central Illinois areas. These services include demand, time,
and savings deposits; lending; mortgage banking; insurance products; brokerage
services; asset management; and trust services. The Company is subject to
competition from other financial institutions, including banks, thrifts and
credits unions, as well as nonfinancial institutions providing financial
services. Additionally, the Company and the Bank are subject to regulations of
certain regulatory agencies and undergo periodic examinations by those
regulatory agencies.

First Quarter Highlights

     o    Earnings per share increased 90.9% compared to the first quarter of
          2005 and 133.3% compared to fourth quarter 2005 levels.

     o    The Company recorded a negative provision of $800 to the allowance for
          loan losses largely based on the pay-off of one $4,400 loan
          relationship that was classified as impaired as of year-end with a
          specific reserve allocation of $1,500. Also contributing to
          management's decision to make the reverse provision were continued
          improvements in the quality of the loan portfolio, favorable loan loss
          experience and management's beliefs regarding the probability and
          estimations of future losses inherent in the loan portfolio.

     o    The net interest margin decreased to 3.50% during the first quarter of
          2006 as compared with 3.52% for the same period in 2005 and 3.60% in
          the fourth quarter of 2005.

     o    The loan portfolio decreased to $406,617 as compared to $417,525 at
          December 31, 2005. Of this $10,908 decrease in outstanding balances,
          approximately $6,800 or 62% was related to the pay-off of action list
          credits refinanced with a competitor. The remainder was due to
          cyclical agriculture elevator pay downs.

     o    The level of nonperforming loans to end of period loans totaled 0.82%
          as of March 31, 2006 compared to 1.19% at March 31, 2005 and 0.96% on
          December 31, 2005.

     o    Net charge-offs for the first quarter of 2006 were 0.01% of average
          loans as compared to (0.03%) for the same period 2005 and 0.06% for
          the fourth quarter of 2005.

     o    The Company's Board of Directors, in a continuing effort to enhance
          stockholder value, approved the payment of a 9.1% increase in the
          quarterly cash dividend to $0.12 from $0.11 on the Company's common
          stock during the first quarter, marking the 84th consecutive quarter
          of dividends paid to stockholders.

     o    The Company repurchased 77,625 shares at a weighted average cost of
          $21.10 of its common stock under the Company's stock repurchase plan.

     o    The Company sold $6,100 of deposits related to the divestiture of its
          Mendota sales and service center.

                                      13.

Results of Operations

     Net Income

         Net income equaled $1,646 or $0.42 per diluted share for the three
months ended March 31, 2006, versus $964 or $0.22 per diluted share for the same
period in 2005.

         The Company's quarterly results were positively impacted by a negative
provision of $800 to the allowance for loan losses. This action was largely
based on the pay-off of one $4,400 loan relationship that was classified as
impaired as of year-end with a specific reserve of $1,500. Additionally,
quarterly earnings were assisted by improved asset quality that allowed lower
than anticipated funding for the provision for loan losses, management of
noninterest expense levels led to decreased expense levels, and fewer FTE's
drove salary and benefit costs lower. These items were partially offset by
increased interest expense due to higher rates and an adverse shift in the
deposit base from lower paying accounts to higher paying deposit products. Also
contributing to the change in earnings were decreases in revenue generated from
the mortgage banking division and insurance and brokerage product lines due to
lower production volumes, and decreases in overdraft and service charge fees due
to lower volume of deposit accounts and balances.

         Return on average assets was 0.99% for the first quarter of 2006
compared to 0.59% for the same period in 2005. Return on average stockholders'
equity was 10.14% for the first quarter of 2006 compared to 5.52% for the same
period in 2005.

     Net Interest Income/ Margin

         Net interest income is the difference between income earned on
interest-earning assets and the interest expense incurred for the funding
sources used to finance these assets. Changes in net interest income generally
occur due to fluctuations in the volume of earning assets and paying liabilities
and the rates earned and paid, respectively, on those assets and liabilities.
The net yield on total interest-earning assets, also referred to as net interest
margin, represents net interest income divided by average interest-earning
assets. Net interest margin measures how efficiently the Company uses its
earning assets and underlying capital. The Company's long-term objective is to
manage those assets and liabilities to provide the largest possible amount of
income while balancing interest rate, credit, liquidity and capital risks. For
purposes of this discussion, both net interest income and margin have been
adjusted to a fully tax equivalent basis for certain tax-exempt securities and
loans.

         Net interest income, on a tax equivalent basis, was $5,314 for the
three months ended March 31, 2006, compared with $5,242 earned during the same
three-month period in 2005. This represented an increase of $72 or 1.4% from the
prior year period. The change in net interest income is attributable to the
increase in interest income earned on interest-earning assets totaling $1,215
partially offset by the increase in interest expense paid on interest bearing
liabilities totaling $1,143.

         The $1,215 increase in interest income resulted from increases of $30
due to volume and $1,185 due to rate. The majority of the change in interest
income was related to the increases in rates experienced from the loan and
investment portfolios. Additionally, the volume within the security portfolio
was $14,587 higher for the first quarter of 2006 as compared to the same period
in 2005. These increases were slightly offset by lower volume in the loan
portfolio.

         The $1,143 increase in interest expense resulted from increases of
$1,025 associated with rate and $118 associated with volume. The majority of the
change was attributable to a 92 basis point increase in rates paid on time

                                      14.

deposits, a 105 basis point increase in rates paid on money market accounts and
a 68 basis point increase in rates paid on NOW accounts.

         The net interest margin decreased 2 basis points to 3.50% in the first
quarter 2006 as compared with 3.52% for the same period in 2005. The expectation
of a flat yield curve is likely to maintain pressure on margins for the
remainder of 2006. Although the margin declined by 2 basis points,
tax-equivalent net interest income increased $72 to $5,314 reported for the
first quarter of 2006 as compared to $5,242 for the first quarter of 2005.

         The Company's net interest income is affected by changes in the amount
and mix of interest-earning assets and interest-bearing liabilities, referred to
as "volume change." It is also affected by changes in yields earned on
interest-earning assets and rates paid on interest-bearing deposits and other
borrowed funds referred to as "rate change." The following table details each
category of average amounts outstanding for interest-earning assets and
interest-bearing liabilities, average rate earned on all interest-earning
assets, average rate paid on all interest-bearing liabilities, and the net yield
on average interest-earning assets. In addition, the table reflects the changes
in net interest income stemming from changes in interest rates and from asset
and liability volume, including mix. The change in interest attributable to both
rate and volume has been allocated to the changes in the rate and the volume on
a pro rata basis.

    Provision for Loan Losses

         The Company recorded a negative provision of $800 to the allowance for
loan losses for the first quarter of 2006 which is a decrease of $900 from the
$100 recorded during the same period a year ago. The decrease in the provision
was primarily due to the payoff of one $4,400 loan relationship that was
classified as impaired as of year-end with a specific reserve of $1,500. Also,
funding of the provision has been lower than anticipated due to continued
improvement in asset quality driven by a net decrease in non-performing and
action/watch list loans from the first quarter of 2005 through the first quarter
of 2006, as well as resolutions, either through charge-off of non-bankable
assets or through successful workout strategies that have been executed.
Nonperforming loans decreased $1,670 from $5,022 as of March 31, 2005 to $3,352
as of March 31, 2006. Net charge-offs for the first quarter of 2006 were $56
compared with ($116) for the comparable period in 2005. Annualized net
charge-offs were 0.01% of average loans for the first quarter of 2006 compared
with (0.03%) of average loans for same period in 2005. See "Nonperforming
Assets" and "Other Potential Problem Loans" for further information.

         The amount of the provision for loan losses is based on management's
evaluations of the loan portfolio, with particular attention directed toward
nonperforming, impaired and other potential problem loans. During these
evaluations, consideration is also given to such factors as management's
evaluation of specific loans, the level and composition of impaired loans, other
nonperforming loans, other identified potential problem loans, historical loss
experience, results of examinations by regulatory agencies, results of the
independent asset quality review process, the market value of collateral, the
estimate of discounted cash flows, the strength and availability of guarantees,
concentrations of credits, and various other factors, including concentration of
credit risk in various industries and current economic conditions.

         Management remains watchful of credit quality issues. Should the
economic climate deteriorate from current levels, borrowers may experience
difficulty, and the level of nonperforming loans, charge-offs and delinquencies
could rise and require further increases in the provision.

     Noninterest Income

         Noninterest income consists of a wide variety of fee-based revenues
from bank-related service charges on deposits and mortgage revenues. Also
included in this category are revenues generated by the Company's insurance,
brokerage, trust and asset management product lines as well as increases in cash
surrender value on bank-owned life insurance. The following table summarizes the
Company's noninterest income:

months ended March 31, 2006, compared to $1,848 for the same period in 2005.
This represented a decrease of $88 or 4.8%. The quarter-over-quarter decrease
was primarily attributable to a decrease in mortgage banking income related to a
slowdown in production volumes (including gains on sale and servicing income,
net of non-cash amortization charges in the carrying value of the mortgage
servicing rights portfolio), decreases in overdraft fees (included in service
charges) and service charge fees due to volume and lower insurance and brokerage
revenue due to new production shortfalls. Additionally, most other fee
categories for the quarter have shown an increase as well when compared to 2005
results for the same period.


     Noninterest Expense

         Noninterest expense is comprised primarily of compensation and employee
benefits, occupancy and other operating expense. The following table summarizes

2006, as compared to $5,546 for the same period in 2005. This represented a
decrease of $212 or 3.8%. This improvement in noninterest expense was primarily
due to lower salary and employee benefits expenses due to fewer FTE's in first
quarter of 2006 and lower loan related costs (included in other expenses). These
positive variances were partially offset by higher expenses in marketing,
occupancy and furniture and equipment expenses. Finally, management's continued
efforts to contain costs have led to decreases in many other expense categories.

     Applicable Income Taxes

         Income tax expense for the periods included benefits for tax-exempt
income, tax-advantaged investments and general business tax credits offset by
the effect of nondeductible expenses. The following table shows the Company's
income before income taxes, as well as applicable income taxes and the effective
tax rate for the three months ended March 31, 2006 and 2005.

         The Company recorded an income tax expense of $763 and of $325 for the
three months ended March 31, 2006 and 2005, respectively. Income tax expense for
the periods included benefits for tax-exempt income, tax-advantaged investments
and general business tax credits offset by the effect of nondeductible expenses.
The Company's effective tax rate was lower than statutory rates due to the
Company deriving interest income from municipal securities and loans, which are
exempt from federal tax and certain U. S. government agency securities, which
are exempt from Illinois State tax. Additionally, the Company has reduced tax
expense through various tax planning initiatives.

         For the first quarter of 2006, the Company has less of its security
portfolio invested in federally tax-exempt assets than in the same period in
2005. Thus, the amount of tax exempt interest earned on the portfolio in the
first quarter of 2006 is lower than the same period of 2005. This change in mix
in the security portfolio increased the amount of interest that is taxable
leading to the higher effective tax rate experienced during the period.
Additionally, total taxable income for the first quarter of 2006 has doubled as
compared to the same period in 2005 which raises the mix of taxable versus
nontaxable income that drives the effective tax rate higher.

     Preferred Stock Dividends

         The Company paid $52 in preferred stock dividends for the three months
ended March 31, 2006 and 2005, respectively.

Interest Rate Sensitivity Management

         The business of the Company and the composition of its balance sheet
consist of investments in interest-earning assets (primarily loans and
securities) which are primarily funded by interest-bearing liabilities (deposits
and borrowings). All of the financial instruments of the Company are for other
than trading purposes. Such financial instruments have varying levels of
sensitivity to changes in market rates of interest. The operating income and net
income of the Bank depends, to a substantial extent, on "rate differentials,"
i.e., the differences between the income the Bank receives from loans,
securities, and other earning assets and the interest expense they pay to obtain
deposits and other liabilities. These rates are highly sensitive to many factors
that are beyond the control of the Bank, including general economic conditions
and the policies of various governmental and regulatory authorities.

         The Company measures its overall interest rate sensitivity through a
net interest income analysis. The net interest income analysis measures the
change in net interest income in the event of hypothetical changes in interest
rates. This analysis assesses the risk of changes in net interest income in the
event of a sudden and sustained 100 to 200 basis point increase in market
interest rates or a 100 basis point decrease in market rates. The interest rates
scenarios are used for analytical purposes and do not necessarily represent
management's view of future market movements. The tables below present the
Company's projected changes in net interest income for the various rate shock
levels at March 31, 2006 and December 31, 2005, respectively:

     Nonperforming Assets

         The Company's financial statements are prepared on the accrual basis of
accounting, including the recognition of interest income on its loan portfolio,
unless a loan is placed on nonaccrual status. Loans are placed on nonaccrual
status when there are serious doubts regarding the collectibility of all
principal and interest due under the terms of the loans. Amounts received on
nonaccrual loans generally are applied first to principal and then to interest
after all principal has been collected. It is the policy of the Company not to
renegotiate the terms of a loan because of a delinquent status. Rather, a loan
is generally transferred to nonaccrual status if it is not in the process of
collection and is delinquent in payment of either principal or interest beyond
90 days. Loans that are 90 days delinquent but are well secured and in the
process of collection are not included in nonperforming assets. Other
nonperforming assets consist of real estate acquired through loan foreclosures
or other workout situations and other assets acquired through repossessions.

         The classification of a loan as nonaccrual does not necessarily
indicate that the principal is uncollectible, in whole or in part. The Bank
makes a determination as to collectibility on a case-by-case basis. The Bank
considers both the adequacy of the collateral and the other resources of the
borrower in determining the steps to be taken to collect nonaccrual loans. The
final determination as to the steps taken is made based upon the specific facts
of each situation. Alternatives that are typically considered to collect
nonaccrual loans are foreclosure, collection under guarantees, loan
restructuring, or judicial collection actions.

         Each of the Company's loans is assigned a rating based upon an
internally developed grading system. A separate credit administration department
also reviews grade assignments on an ongoing basis. Management continuously
monitors nonperforming, impaired, and past due loans to prevent further
deterioration of these loans. The Company has an independent loan review
function which is separate from the lending function and is responsible for the
review of new and existing loans.

         The following table summarizes nonperforming assets and loans past due
90 days or more and still accruing for the previous five quarters.

     Other Potential Problem Loans

         The Company has other potential problem loans that are currently
performing, but where some concerns exist as to the ability of the borrower to
comply with present loan repayment terms. Excluding nonperforming loans and
loans that management has classified as impaired, these other potential problem
loans totaled $858 at March 31, 2006 as compared to $7,728 at March 31, 2005 and
$2,879 at December 31, 2005. The classification of these loans, however, does
not imply that management expects losses on each of these loans, but believes
that a higher level of scrutiny and close monitoring is prudent under the
circumstances. Such classifications relate to specific concerns for each
individual borrower and do not relate to any concentration risk common to all
loans in this group.

     Allowance for Loan Losses

         At March 31, 2006, the allowance for loan losses was $7,506 or 1.85% of
total loans as compared to $8,362 or 2.00% at December 31, 2005, and $9,948 or
2.36% at March 31, 2005. The decrease in the allowance was primarily related to
the Company recording a negative provision of $800 to the allowance for loan
losses during the first quarter. This negative provision was related to the
payoff of one $4,400 loan relationship that was classified as impaired as of
year-end with a specific reserve of $1,500. In originating loans, the Company
recognizes that credit losses will be experienced and the risk of loss will vary
with, among other things, general economic conditions; the type of loan being
made; the creditworthiness of the borrower over the term of the loan; and, in
the case of a collateralized loan, the quality of the collateral for such a
loan. The allowance for loan losses represents the Company's estimate of the
allowance necessary to provide for probable incurred losses in the loan
portfolio. In making this determination, the Company analyzes the ultimate
collectibility of the loans in its portfolio, incorporating feedback provided by
internal loan staff, the independent loan review function, and information
provided by examinations performed by regulatory agencies. The Company makes an
ongoing evaluation as to the adequacy of the allowance for loan losses.

         On a quarterly basis, management reviews the adequacy of the allowance
for loan losses. Commercial credits are graded by the loan officers and the Loan
Review function validates the officers' grades. In the event that the loan
review function downgrades the loan, it is included in the allowance analysis at
the lower grade. The grading system is in compliance with the regulatory
classifications and the allowance is allocated to the loans based on the
regulatory grading, except in instances where there are known differences (i.e.,
collateral value is nominal, etc.). To establish the appropriate level of the
allowance, a sample of loans (including impaired and nonperforming loans) are
reviewed and classified as to potential loss exposure.

         Based on an estimation computed pursuant to the requirements of
Financial Accounting Standards Board ("FASB") Statement No. 5, "Accounting for
Contingencies," and FASB Statements Nos. 114 and 118, "Accounting by Creditors
for Impairment of a Loan," the analysis of the allowance for loan losses
consists of three components: (i) specific credit allocation established for
expected losses resulting from analysis developed through specific credit
allocations on individual loans for which the recorded investment in the loan
exceeds its fair value; (ii) general portfolio allocation based on historical
loan loss experience for each loan category; and (iii) subjective reserves based
on general economic conditions as well as specific economic factors in the
markets in which the Company operates.

         The specific credit allocation component of the allowance for loan
losses is based on a regular analysis of loans over a fixed-dollar amount where
the internal credit rating is at or below a predetermined classification. The
fair value of the loan is determined based on either the present value of
expected future cash flows discounted at the loan's effective interest rate, the
market price of the loan, or, if the loan is collateral dependent, the fair
value of the underlying collateral less cost of sale.

                                      22.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF

(In Thousands, Except Per Share Data)
--------------------------------------------------------------------------------
         The general portfolio allocation component of the allowance for loan
losses is determined statistically using a loss migration analysis that examines
historical loan loss experience. The loss migration analysis is performed
quarterly and loss factors are updated regularly based on actual experience. The
general portfolio allocation element of the allowance for loan losses also
includes consideration of the amounts necessary for concentrations and changes
in portfolio mix and volume.

         The allowance for loan losses is based on estimates, and ultimate
losses will vary from current estimates. These estimates are reviewed monthly,
and as adjustments, either positive or negative, become necessary, a
corresponding increase or decrease is made in the provision for loan losses. The
composition of the loan portfolio has not significantly changed since year-end
2004. The methodology used to determine the adequacy of the allowance for loan
losses is consistent with prior years, and there were no reallocations.

         Management remains watchful of credit quality issues. Should the
economic climate deteriorate from current levels, borrowers may experience
difficulty, and the level of nonperforming loans, charge-offs and delinquencies
could rise and require further increases in the provision.

     Liquidity

         The Company manages its liquidity position with the objective of
maintaining sufficient funds to respond to the needs of depositors and borrowers
and to take advantage of earnings enhancement opportunities. In addition to the
normal inflow of funds from core-deposit growth together with repayments and
maturities of loans and investments, the Company utilizes other short-term
funding sources such as brokered time deposits, securities sold under agreements
to repurchase, overnight federal funds purchased from correspondent banks and
the acceptance of short-term deposits from public entities, and Federal Home
Loan Bank advances.

         The Company monitors and manages its liquidity position on several
bases, which vary depending upon the time period. As the time period is
expanded, other data is factored in, including estimated loan funding
requirements, estimated loan payoffs, investment portfolio maturities or calls,
and anticipated depository buildups or runoffs.

         The Company classifies all of its securities as available-for-sale,
thereby maintaining significant liquidity. The Company's liquidity position is
further enhanced by structuring its loan portfolio interest payments as monthly
and by the significant representation of retail credit and residential mortgage
loans in the Company's loan portfolio, resulting in a steady stream of loan
repayments. In managing its investment portfolio, the Company provides for
staggered maturities so that cash flows are provided as such investments mature.

         The Company's cash flows are comprised of three classifications: cash
flows from operating activities, cash flows from investing activities, and cash
flows from financing activities. Cash flows used in financing activities offset
by those provided by operating activities and investing activities, resulted in
a net decrease in cash and cash equivalents of $8,607 from December 31, 2005 to
March 31, 2006.

         During the first three months of 2006, the Company experienced net cash
outflows of $9,355 in financing activities primarily due to a decrease in
deposits and $487 in investing activities largely due to the decrease in net
loans and securities. In contrast, net cash inflows of $1,260 were provided by
operating activities due to negative provision and net income.

Capital Resources

     Stockholders' Equity

         The Company is committed to managing capital for maximum shareholder
benefit and maintaining strong protection for depositors and creditors.
Stockholders' equity at March 31, 2006 was $65,369, a decrease of $706 or 1.1%,
from December 31, 2005. The decrease in stockholders' equity was largely the
result of stock repurchase activity, dividends paid to shareholders and a
decrease in accumulated other comprehensive income. Average quarterly equity as
a percentage of average quarterly assets was 9.80% at March 31, 2006, compared
to 10.39% at December 31, 2005. Book value per common share equaled $17.33 at
March 31, 2006 compared to $17.23 at December 31, 2005.

     Stock Repurchase

         On May 2, 2003, the Board of Directors approved a stock repurchase plan
whereby the Company may repurchase from time to time up to 5% of its outstanding
shares of common stock in the open market or in private transactions over an 18
month period. On September 23, 2004, the Board of Directors extended the
Company's stock repurchase program through May 2, 2006. On June 16, 2005, the
Board of Directors amended the repurchase plan to enable the Company to acquire
an additional 5% of its outstanding shares of common stock in the open market or
in private transactions. On March 16, 2006, the Board of Directors approved an
additional 5% stock repurchase program that begins when the existing plan is
completed. Under the revised plan, the Company can repurchase approximately
188,000 shares of its outstanding shares of common stock. Under the terms of the
plan, the Company is able to repurchase, from time to time, up to 5% of its
outstanding shares of common stock in the open market or in private
transactions. Purchases are dependent upon market conditions and the

availability of shares. The extension of the repurchase program enables the
Company to optimize its use of capital relative to other investment alternatives
and benefits both the Company and the shareholders by enhancing earnings per
share and return on equity. During the current quarter, 77,625 shares were
repurchased at a weighted cost of $21.10 and to date, the Company has
repurchased 364,879 shares at a weighted average cost of $21.16

     Capital Measurements

         The Bank is expected to meet a minimum risk-based capital to
risk-weighted assets ratio of 8%, of which at least one-half (or 4%) must be in
the form of Tier 1 (core) capital. The remaining one-half (or 4%) may be in the
form of Tier 1 (core) or Tier 2 (supplementary) capital. The amount of loan loss
allowance that may be included in capital is limited to 1.25% of risk-weighted
assets. The ratio of Tier 1 (core) and the combined amount of Tier 1 (core) and
Tier 2 (supplementary) capital to risk-weighted assets for the Company was 12.2%
and 13.5%, respectively, at March 31, 2006. The Company is currently, and
expects to continue to be, in compliance with these guidelines.

         The following table sets forth an analysis of the Company's capital
ratios:

Impact of Inflation, Changing Prices, and Monetary Policies

         The financial statements and related financial data concerning the
Company have been prepared in accordance with U.S. generally accepted accounting
principles which require the measurement of financial position and operating
results in terms of historical dollars without considering changes in the
relative purchasing power of money over time due to inflation. The primary
effect of inflation on the operations of the Company is reflected in increased
operating costs. Unlike most industrial companies, virtually all of the assets
and liabilities of a financial institution are monetary in nature. As a result,
changes in interest rates have a more significant effect on the performance of a
financial institution than do the effects of changes in the general rate of
inflation and changes in prices. Interest rates do not necessarily move in the
same direction or in the same magnitude as the prices of goods and services.
Interest rates are highly sensitive to many factors which are beyond the control
of the Company, including the influence of domestic and foreign economic
conditions and the monetary and fiscal policies of the United States government
and federal agencies, particularly the Federal Reserve Board.

Recent Regulatory and Accounting Developments

         In February, 2006, the FASB issued SFAS No. 155, "Accounting for
Certain Hybrid Financial Instruments - An Amendment of FASB Statement No. 133
and 140" ("SFAS155"). SFAS 155 simplifies the accounting for certain hybrid
financial instruments that contain an embedded derivative that otherwise would
have required bifurcation. SFAS 155 also eliminates the interim guidance in FASB
Statement No. 133, which provides that beneficial interest in securitized
financial assets are not subject to the provisions of FASB Statement No. 133.
SFAS 155 is effective for all financial instruments acquired or issued after the
beginning of an entity's first fiscal year that begins after September 15, 2006,
which for the Company will be as of the beginning of fiscal 2007. The Company
does not believe that the adoption of SFAS 155 will have a significant effect on
its financial statements as the Company does not have any hybrid financial
instruments at this time.

         In March, 2006, the FASB issued SFAS No. 156, "Accounting for Servicing
of Financial Assets - An Amendment of FASB Statement No. 140" ("SFAS 156"). SFAS
156 requires that all separately recognized servicing assets and servicing
liabilities be initially measured at fair value, if practicable. The statement
permits, but does not require, the subsequent measurement of servicing assets
and servicing liabilities at fair value. SFAS 156 is effective as of the
beginning of the entity's first fiscal year that begins after September 15,
2006. The Company is currently evaluating any potential impact of the adoption
of this SFAS.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

         The information required by this Item 3 is incorporated by reference
from the discussion on pages 19 and 20 of this Form 10-Q under the caption
"Interest Rate Sensitivity Management" and the discussion immediately above
under the caption "Impact of Inflation, Changing Prices, and Monetary Policies."

Item 4.  Controls and Procedures

         As of the end of the period covered by this report, the Company carried
out an evaluation under the supervision and with the participation of the
Company's management, including the Company's Chief Executive Officer and Chief
Financial Officer, of the Company's disclosure controls and procedures (as
defined in Rule 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of
1934, as amended). Based on this evaluation, the Company's Chief Executive
Officer and Chief Financial Officer concluded that the Company's disclosure
controls and procedures were effective in timely alerting them to material
information relating to the Company required to be included in the Company's
periodic filings with the Securities and Exchange Commission. It should be noted
that in designing and evaluating the disclosure controls and procedures,
management recognized that any controls and procedures, no matter how well
designed and operated, can provide only reasonable assurance of achieving the
desired control objectives, and management necessarily was required to apply its
judgment in evaluating the cost-benefit relationship of possible controls and
procedures. The Company has designed its disclosure controls and procedures to
reach a level of reasonable assurance of achieving the desired control
objectives and, based on the evaluation described above, the Company's Chief
Executive Officer and Chief Financial Officer concluded that the Company's
disclosure controls and procedures were effective at reaching that level of
reasonable assurance.

         There was no change in the Company's internal control over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities
Exchange Act of 1934, as amended) during the Company's most recently completed
fiscal quarter that has materially affected, or is reasonably likely to
materially affect, the Company's internal control over financial reporting.

          (1)  The Company repurchased 77,625 shares at an average price per
               share of $21.10 of our common stock during the quarter ended

               program. The current repurchase program approved on June 16, 2005
               provides for the repurchase by us of up to an aggregate of 5% of
               the outstanding shares of our common stock. The expiration date
               of this program is May 2, 2006. Unless terminated earlier by
               resolution of our board of directors, the program will expire on
               the earlier of such expiration date or when we have repurchased
               all shares authorized for repurchase under the program.

          (2)  On March 23, 2006, our board of directors approved an additional
               5% stock repurchase program that will begin when the existing
               plan approved on June 16, 2005 is completed. Under the new plan,
               the Company will repurchase over an 18-month period up to
               approximately 188,000 shares of its outstanding shares of common
               stock in the open market or in private transactions.
