Note 1.  Basis of Presentation and 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 and nine months ended September 30, 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.

         The consolidated financial statements have been restated to report the
results of the Company's Insurance unit of the Wealth Management segment as a
discontinued operation as described in Note 8.

Note 2.  Earnings Per Share

         Basic earnings per share for the three and nine months ended September
30, 2006 and 2005 were computed by dividing net income by the weighted average
number of shares outstanding. Diluted earnings per share for the three and nine
months ended September 30, 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
September 30, 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 3.  Securities

         The Company's consolidated securities portfolio, which represented
30.8% of the Company's 2006 third quarter average earning asset base, is managed
to minimize interest rate risk, maintain sufficient liquidity, and maximize
return. The portfolio includes several callable agency debentures, adjustable
rate mortgage pass-throughs, and collateralized mortgage obligations. Corporate
bonds consist of investment grade obligations of public corporations. Equity
securities consist of Federal Reserve stock, Federal Home Loan Bank stock, and
trust preferred stock. Securities classified as available-for-sale, carried at
fair value, were $182,171 at September 30, 2006 compared to $196,440 at December
31, 2005. The Company does not have any securities classified as trading or
held-to-maturity.

         The following table describes the fair value, gross unrealized gains
and losses of securities available-for-sale at September 30, 2006 and December

Note 4.  Loans and Allowance For Loan Losses (Continued)

         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 and nine months ended September 30, 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
third quarter of 2006 and 2005 was $310 and $375. The company recorded $103 in
stock compensation expense during the nine months ended September 30, 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 17,500 of grants issued during the nine
months ended September 30, 2006 and no grants were issued for the nine months
ended September 30, 2005.

         The Company elected to adopt the modified prospective application
method as provided by SFAS 123R, and, accordingly the Company recorded
compensation costs as the requisite service rendered for the

                                      10.

Note 5.  Stock Option Plans (Continued)

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 123R.

         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:

Note 6.  Contingent Liabilities And Other Matters

         Neither the Company nor any of its subsidiaries are involved in any
pending legal proceedings other than routine legal proceedings occurring in the
normal course of business, which, in the opinion of management, in the
aggregate, are not material to the Company's consolidated financial condition.

Note 7.  Segment Information

         The reportable segments are determined by the products and services
offered, primarily distinguished between retail, commercial, treasury, wealth
management, and operations & other. Loans, and deposits generate the revenues in
the commercial segments; deposits, loans, secondary mortgage sales and servicing
generates the revenue in the retail segment; investment income generates the
revenue in the treasury segment; brokerage and trust services generate the
revenue in the wealth management segment (formerly known as the Financial
Services segment); and holding company services and discontinued operations
associated with the sale of the insurance segment generate the revenue in the
operations & other segment. With the sale of the Insurance unit, the results for
Insurance were reclassified into the Operations & Other segment from the
Financial Services segment (which is now referred to as Wealth Management).

         The accounting policies used with respect to segment reporting are the
same as those described in the summary of significant accounting policies set
forth in Note 1 on page 4. Segment performance is evaluated using net income.
Information reported internally for performance assessment follows.

Note 8. -- Discontinued Operations

         The Company sold the Insurance unit of their Wealth Management segment
to the Phoenix Group for $1.2 million and the deal closed on September 29, 2006.
The sale price is subject to final adjustments until December 28, 2006. The
Company and Phoenix Group have until this date to evaluate any accounts
receivable balances that are ninety days or more past due as of the date of the
sale that is not collected in full within ninety days, at the sole discretion of
the Phoenix Group, is subject to repurchase by the Company. The Company does not
anticipate any significant changes at this time.

         In accordance with FASB Statement No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets" ("FAS 144") the results of
operations of the insurance division are reflected in the Company's statements
of income for the three and nine months ended September 30, 2006 and 2005 as
"discontinued operations." The loss on the sale of the insurance unit of $355
thousand and related tax benefit of $138 thousand are included in discontinued
operations for the three and nine months ended September 30, 2006. Additionally,
approximately $1,030 of goodwill and intangibles attributed to the Insurance
unit on the Company's balance sheet were written off as a result of this
transaction and factored into the loss on the sale of the discontinued
operations.

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

--------------------------------------------------------------------------------

         The following discussion provides an analysis of the Company's results
of operations and financial condition for the three and nine months ended
September 30, 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 and nine months ended September 30, 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 wealth management 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.

OPERATIONS

Results of Operations

      Net Income

         Income from continuing operations equaled $1,506 or $0.38 per diluted
share for the three months ended September 30, 2006 compared to $1,118 or $0.26
per diluted share earned for same period in 2005. The Company recorded a net
loss of ($270) or ($0.07) per diluted share from discontinued operations related
to the recent sale of the insurance group. Net income for the period was $1,184
or $0.31 per diluted share as compared to $1,009 or $0.25 per diluted share for
the same period in 2005.

         For the nine months ended September 30, 2006, net income equaled $4,020
or $1.06 per diluted share compared to $3,251 or $0.80 per diluted share earned
in the same period during 2005. During this period, the Company reported a net
loss of ($327) or ($0.08) per diluted share related to the discontinued
operations for the insurance group as compared to a net loss of ($143) or
($0.04) per diluted share for the same period in 2005. For continuing
operations, the Company reported results of $4,503 or $1.14 per diluted share as
compared with earnings of $3,550 or $0.84 per diluted share for the same period.

         The Company's quarterly results from continuing operations were
positively impacted by a negative provision of $200 to the allowance for loan
losses. This action was largely based on 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. Additionally, quarterly earnings were assisted by continued
management of noninterest expense levels which led to decreased expense levels,
and fewer FTE's drove salary and benefit costs lower and lower accounting and
professional fees. These items were partially offset by increased interest
expense due to higher rates and an adverse shift in the deposit base from lower
paying core deposit accounts to higher paying time deposit accounts. Also
contributing to the change in earnings were decreases in revenue generated from
the mortgage banking division and brokerage product lines due to lower
production volumes.

         Return on average assets was 0.76% for the third quarter of 2006
compared to 0.64% for the same period in 2005. Return on average assets was
0.85% for the nine month period ended September 30, 2006 compared to 0.69% for
the same period in 2005.

         Return on average stockholders' equity was 7.32% for the third quarter
of 2006 compared to 6.18% for the same period in 2005. Return on average
stockholder's equity was 8.43% for the nine month period ended September 30,
2006 compared to 6.55% 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 $5,206 for the
three months ended September 30, 2006, compared with $5,365 earned during the
same three-month period in 2005. This represented a decrease of $159 or 3.0%
from the prior year period. The change in net interest income is attributable to
the increase in interest expense paid on interest bearing liabilities totaling
$1,226 partially offset by an increase in interest income earned on interest
earning assets totaling $1,067.

         The $1,067 increase in interest income resulted from an increase of
$1,218 due to rate partially offset by a decrease of $151 due to volume. The
majority of the change in interest income was related to the increases in rates
experienced from the loan and investment portfolios. The volume within the
security and loan portfolios were lower for the third quarter of 2006 as
compared to the same period in 2005.

         The $1,226 increase in interest expense resulted from increases of
$1,213 associated with rate and $13 associated with volume. The majority of the
change was attributable to a 98 basis point increase overall in rates paid on
the deposit portfolio. Specifically, the rates for time deposit products
increased by 102 basis points. There was an increase in rates paid on money
market accounts of 102 basis points. Also, the rates paid on NOW accounts
increased by 52 basis points.

         The net interest margin decreased 4 basis points to 3.49% in the third
quarter 2006 as compared with 3.53% 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.

         Net interest income, on a tax equivalent basis, for the nine months
ended September 30, 2006 totaled $15,602, representing a decrease of $447 or
2.8% compared to the $16,049 earned during the same period in 2005. Net interest
income decreased largely due to the increase in interest expense paid on
interest bearing liabilities totaling $3,628 exceeding the increase in the
interest income earned on interest-earning assets totaling $3,181. The net
interest margin for the first nine months of 2006 decreased 9 basis points to
3.46% compared to 3.55% for the same period in 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 $200 to the allowance for
loan losses for the third quarter of 2006 which is a decrease of $250 from the
$50 recorded during the same period a year ago. A negative $1,300 provision for
the loan losses was charged to operation expense for the nine months ended
September 30, 2006 which was a decrease of $1,450 from $150 recorded during the
same period a year ago. The decrease in the provision was largely based on
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. Nonperforming loans decreased $505
from $3,726 as of September 30, 2005 to $3,221 as of September 30, 2006. In
comparison to December 31, 2005, nonperforming loans decreased $783 from $4,004.

         Net charge-offs for the third quarter of 2006 were $545 compared with
$716 for the comparable period in 2005. Annualized net charge-offs were 0.14% of
average loans for the third quarter of 2006 compared with 0.17% of average loans
for same period in 2005. Net charge-off for the nine months ended September 30,
2006 were $959 compared with $1,389 for the comparable period in 2005.
Annualized net charge-offs also decreased to 0.23% of average loans for the nine
months ended September 30, 2006 compared to 0.34% in the 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 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:

         Noninterest income totaled $1,481 for the three months ended September

gains on sale of assets and net securities gains for both periods, noninterest
income equaled $1,482 for the three months ended September 30, 2006, compared to
$1,702 for the same period in 2005. This represented a decrease of $220 or
12.9%. The quarter-over-quarter decrease was primarily attributable to a
production level decrease in revenue generated from the mortgage banking
division, and lower brokerage revenues.

         Noninterest income totaled $4,325 for the nine months ended September
30, 2006, compared to $4,893 for the same time frame in 2005. Excluding all net
gains on sale of assets and net securities gains for both periods, noninterest
income decreased $475 or 10.0%. The change was largely reflective of the same
items discussed regarding the third quarter. Additionally, results were impacted
by the impact related to losses for investment activities.

benefits, occupancy and other operating expense. The following table summarizes

30, 2006, decreasing by $1,353 or 8.7% from the same period in 2005. The change
was largely reflective of the same items discussed regarding the third quarter.

      Applicable Income Taxes

         Income tax expense for the periods included benefits for tax-exempt
income, tax-advantaged investments, loss from discontinued operations and
general business tax credits offset by the effect of nondeductible expenses. For
the third quarter, the Company's effective tax rate overall was 28.3% as its
total applicable taxes were $488 on pretax earnings of $1,724. for The following

respectively, for such periods.

         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.

         The Company recorded income tax expense of $1,983 and $1,076 on income
from continuing operations for the nine months ended September 30, 2006 and
2005, respectively. Effective tax rates equaled 30.8% and 23.3% respectively,
for such periods.

      Preferred Stock Dividends

         The Company paid $52 in preferred stock dividends for the three months
ended September 30, 2006 and 2005, respectively. The Company paid $156 in
preferred stock dividends for the nine months ended September 30, 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 or decrease in
market interest 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 September 30, 2006 and
December 31, 2005, respectively:

Financial Condition

      General

         As of September 30, 2006, the Company had total assets of $648,851,
total gross loans of $400,912, total deposits of $526,918 and total
stockholders' equity of $67,304. Total assets decreased by $27,371 or 4.0% from
year-end 2005 related primarily to decline in the investment portfolio. Total
gross loans decreased by $10,510 or 2.5% from year-end 2005. Total deposits
declined by $16,923 or 3.1% from year-end 2005. These changes were implemented
to reduce the investment portfolio as with the flat yield curve the Company was
experiencing slim spreads over its cost of funds. Thus, the cost of funds which
was the primarily the FHLB advances was reduced as the investments were sold.

      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.

September 30, 2005. The level of nonperforming loans to total end of period
loans was 0.79% at September 30, 2006, as compared to 0.96% at December 31, 2005
and 0.92% at September 30, 2005. The reserve coverage ratio (allowance to
nonperforming loans) was reported at 189.48% as of September 30, 2006 as
compared to 208.84% as of December 31, 2005 and 227.94% as of September 30,
2005.

           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 $3,785 at September 30, 2006, as compared to $6,339 at September
30, 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 September 30, 2006, the allowance for loan losses was $6,103 or
1.50% of total loans as compared to $8,362 or 2.00% at December 31, 2005, and
$8,493 or 2.09% at September 30, 2005. The decrease in the allowance was largely
based on 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. This continued
improvement in asset quality has been driven by the decrease in non-performing
and watch list loans as well as resolutions, either through charge-off of
non-bankable assets or through the successful workout strategies that have been
executed. The Company's loans with specific reserves under FASB No. 114 assigned
to them have continued to decrease throughout the year. As of September 30, 2006
the Company has approximately $2,398 of specific reserves compared to $4,682 as
of December 31, 2005. 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.

         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
2005. The methodology used to determine the adequacy of the allowance for loan
losses is consistent with prior years, and there were no material 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 provided by operating activities and
investing activities offset by those used in financing activities, resulted in a
net decrease in cash and cash equivalents of $4,307 from December 31, 2005 to
September 30, 2006.

         During the first nine months of 2006, the Company experienced net cash
in flows of $3,504 in operating activities due to negative provision and net
income and $17,047 in investing activities largely due to the decrease in net

         If the announced merger between UnionBancorp, Inc. and Centrue
Financial Corporation (NASDAQ: TRUE) is terminated, UnionBancorp, Inc is
required to fulfill the certain specified obligations to make certain payments
to Centrue Financial Corporation as described below:

     o   If the merger agreement is terminated by Centrue because UnionBancorp
         has not satisfied its conditions or the closing has not occurred by
         March 1, 2007 and UnionBancorp knowingly breached its covenants,
         agreements, representations or warranties under the merger agreement
         (unless such breach is a result of the failure by Centrue to perform
         and comply with any of its obligations) then, provided Centrue is in
         compliance with its obligations under the merger agreement,
         UnionBancorp must pay $2,700 to Centrue.

     o   If the merger agreement is terminated by UnionBancorp or Centrue
         because UnionBancorp's stockholders fail to approve the merger (a
         "UnionBancorp Stockholder Termination"); then, provided Centrue is in
         compliance with its obligations under the merger agreement,
         UnionBancorp must pay $500 to Centrue.

     o   In addition to the $500 payment described above (if any), if there is a
         UnionBancorp Stockholder Termination and, within twelve months after
         such UnionBancorp Stockholder Termination, UnionBancorp enters into an
         agreement with any party other than Centrue providing for the
         acquisition of UnionBancorp, then, provided Centrue was in compliance
         with its obligations under the merger agreement, UnionBancorp must pay
         $2,200 to Centrue.

     o   If UnionBancorp terminates the merger agreement as a result of a
         superior UnionBancorp Proposal, then UnionBancorp must pay $2,700 to
         Centrue.


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 September 30, 2006 was $67,313, an increase of $1,238 or
1.8%, from December 31, 2005. The increase in stockholders' equity was the
result of the net income for the period partially offset by the dividends paid
to shareholders and a decrease in accumulated other comprehensive income.
Average quarterly equity as a percentage of average quarterly assets was 10.34%
at September 30, 2006, compared to 10.01% at December 31, 2005. Book value per
common share equaled $17.85 at September 30, 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


                                      29.

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 quarter ending September 30, 2006, no
shares were repurchased and to date, the Company has repurchased 364,879 shares
at a weighted average cost of $21.16.

      Capital Measurements

         The Company 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 12.4%
and 13.6%, respectively, at September 30, 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" ("SFAS 155"). 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.

         In September, 2006, the FASB issued SFAS No. 157, "Fair Value
Measurements" ("SFAS 157"). SFAS 157 defines fair value, establishes a framework
for measuring fair value and expands disclosures about fair value measurements.
This statement does not require any new fair value measurements. It is effective
for financial statements issued for fiscal years beginning after November 15,
2007. The Company is currently evaluating the impact of the adoption of SFAS
157, with respect to its current practice of measuring fair value and disclosure
in its financial statements.

         In June, 2006, the FASB issued Interpretation No. 48, "Accounting for
Uncertainty in Income Taxes - An Interpretation of FASB No. 109" ("FIN 48"). FIN
48 prescribes a recognition threshold and measurement attribute for the
financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. The Interpretation is effective for fiscal
years beginning after December 15, 2006. The Company is currently evaluating the
impact of the adoption of FIN 48, with respect to its results of operations,
financial position and liquidity.

         In September, 2006, the U.S. Securities and Exchange Commission ("SEC")
amended Part 211 of Title 17 of the Code of Federal Regulations by adding the
Staff Accounting Bulletin No. 108, "Considering the Effects of Prior Year
Misstatements when Quantifying Misstatements in Current Year Financial
Statements" ("SAB 108"). SAB 108 provides guidance on the consideration of the
effects of prior year misstatements in quantifying current year misstatements
for the purpose of a materiality assessment. SAB 108 is effective for fiscal
years ending after November 15, 2006. The Company is reviewing this accounting
bulletin, but has not yet determined the effect of adopting the Interpretation.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

         The information required by this Item 3 is incorporated by reference
from the discussion on page 24 of this Form 10-Q under the caption "Interest
Rate Sensitivity Management" and the discussion on page 31 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/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.

                           PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

         In the normal course of business the Company may be involved in various
legal proceedings from time to time. The Company does not believe it is
currently involved in any claim or action the ultimate disposition of which
would have a material adverse effect on the Company's financial statements.

Item 1A. Risk Factors

         The Company did not experience any material changes in the Risk Factors
during the Company's most recently completed fiscal quarter. For specific
information about the risks facing the Company refer to the Company's Annual
