FOR IMMEDIATE RELEASE



                UNIONBANCORP, INC. REPORTS THIRD QUARTER EARNINGS


OTTAWA, IL, November 1, 2004 - Dewey R. Yaeger, President and Chief Executive
Officer of UnionBancorp, Inc. (Nasdaq: UBCD), announced third quarter earnings
of $2,617,000 or $0.62 per diluted share. Third quarter 2004 earnings included
an approximate $1.7 million net gain on sale associated with the Company's
divestiture of five western Illinois branch locations. Third quarter 2004
earnings compare to a net loss of $869,000 or $0.23 per diluted share earned in
the third quarter of 2003. The Company's third quarter 2003 results were
adversely impacted by a $4.4 million provision for loan losses. For the nine
months ended September 30, 2004, net income equaled $4,330,000 or $1.02 per
diluted share compared to $2,384,000 or $0.54 per diluted share earned in the
same period during 2003.

Commenting on the quarter, Yaeger stated, "The completion of several key
strategic initiatives, including the sale of five of our western Illinois branch
offices, has allowed us to re-focus on our core business operations. We are
encouraged by continued improvement in asset quality trends, particularly in our
levels of nonperforming loans and charge-offs. Going forward, our strategic
growth efforts will focus largely on heightened revenue."

Third Quarter 2004 Highlights:

     o    The Company completed the sale of five of its western Illinois branch
          offices on September 10, 2004, selling $40.4 million in loans and
          $88.6 million in deposits to First Bankers Trust Company of Quincy.
          The transaction, which effectively exited the Company from the western
          Illinois market, yielded a net gain on sale (after impairment of
          intangible assets, taxes and applicable expenses) of approximately
          $1.7 million and reduced the Company's net footings by $40.9 million.

     o    The net interest margin remained relatively stable over the previous
          four quarters, reported at 3.38% at the end of the third quarter 2004.

     o    The level of nonperforming loans to total end of period loans totaled
          1.09% as of September 30, 2004, compared to 2.11% on September 30,
          2003 and 1.78% at December 31, 2003.

     o    Net charge-offs for the third quarter were 0.10% of average loans, as
          compared to 0.52% for third quarter 2003.

     o    The reserve coverage ratio (allowance to nonperforming loans) was
          reported at 220.20% as of September 30, 2004 as compared to 89.01% as
          of September 30, 2003 and 106.30% as of December 31, 2003.



     o    Loan demand in the third quarter remained soft, as total loans
          decreased $62.9 million to $413.9 million since December 31, 2003. Of
          the $60.9 million decrease in loans, $40.4 million or 64.23% was
          associated with the sale of the Company's western Illinois branch
          offices. The remaining decrease was due to tighter underwriting
          standards, a continued softening of overall loan demand and normal
          paydowns.

     o    The Company's Board of Directors approved the payment of a $0.10
          quarterly cash dividend on the Company's common stock, marking the
          78th consecutive quarter of dividends paid to stockholders.

Net Interest Margin

The net interest margin for third quarter 2004 was 3.38%, up slightly from 3.34%
for third quarter 2003, 3.34% from first quarter 2004 and 3.31% for the second
quarter 2004. Tax-equivalent net interest income decreased to $5.5 million for
third quarter 2004 as compared to $6.7 million for 2003's third quarter. This
decrease resulted from repricing of earning assets and a shift in our earning
assets from higher yielding loans to lower yielding investments.

Noninterest Income and Expense

Noninterest income, excluding securities gains and the gain on the sale of the
five western Illinois branch locations, decreased from $3,200,000 to $2,359,000.
The decrease was primarily related to a drop in revenue generated from the
mortgage banking division (including gains on sale and servicing income, net of
non-cash amortization charges in the carrying value of the mortgage servicing
rights portfolio) and a decline in service charge fee income.

Noninterest expense, excluding $987,000 in impairment charges and related
expenses due to the sale of the Company's five western Illinois branch
locations, experienced a $634,000 or 9% decrease on a quarter-over-quarter
basis. The significant improvement was primarily a result of decreased salary
and benefits costs.

Asset Quality

During the first nine months of 2004, the loan portfolio decreased 13.2% to
$413.9 million, as compared to $476.8 million at December 31, 2003. Of the $62.9
million decrease in loans, $40.4 million or 64.2% was associated with the sale
of the Company's five western Illinois branch offices. The remaining decrease
was due to tighter underwriting standards, a continued softening of overall loan
demand and normal paydowns. The level of nonperforming loans to total end of
period loans totaled 1.09% as of September 30, 2004 compared to 2.11% on
September 30, 2003 and 1.78% at December 31, 2003. Net charge-offs for the third
quarter were 0.10% of average loans, as compared to 0.52% for third quarter
2003. The reserve coverage ratio (allowance to nonperforming loans) was reported
at 220.20% as of September 30, 2004 as compared to 89.01% as of September 30,
2003 and 106.30% as of December 31, 2003.
