                             UNIONBANCORP, INC.

           PURSUANT TO SECTION 151 OF THE GENERAL CORPORATION LAW
                          OF THE STATE OF DELAWARE

     UNIONBANCORP, INC., a corporation organized and existing under the General
Corporation Law of the State of Delaware, in accordance with the provisions of
Section 103 thereof, DOES HEREBY CERTIFY:

     That pursuant to the authority vested in the Board of Directors in
accordance with the provisions of the Certificate of Incorporation of the said
Corporation, the said Board of Directors on July 17, 1996 adopted the following
resolution creating a series of 4,500 shares of Preferred Stock designated as
"Series C Junior Participating Preferred Stock":

           RESOLVED, that pursuant to the authority vested in the Board
      of Directors of this Corporation in accordance with the provisions
      of the Certificate of Incorporation, a series of Preferred Stock,
      no par value, of the Corporation be and hereby is created, and

                 SERIES C JUNIOR PARTICIPATING PREFERRED STOCK

     1. Designation and Amount.  There shall be a series of Preferred Stock
that shall be designated as "Series C Junior Participating Preferred Stock,"
and the number of shares constituting such series shall be 4,500.  Such number
of shares may be increased or decreased by resolution of the Board of
Directors; provided, however, that no decrease shall reduce the number of
shares of Series C Junior Participating  Preferred Stock to less than the
number of shares then issued and outstanding plus the number of shares issuable
upon exercise of outstanding rights, options or warrants or upon conversion of
outstanding securities issued by the Corporation.

     2. Dividends and Distribution.

     (A) Subject to the prior and superior rights of the holders of any shares
of any class or series of stock of the Corporation ranking prior and superior
to the shares of Series C Junior Participating Preferred Stock with respect to
dividends, the holders of shares of Series C Junior Participating  Preferred
Stock, in preference to the holders of shares of any class or series of stock
of the Corporation ranking junior to the Series C Junior Participating
Preferred Stock in respect thereof, shall be entitled to receive, when, as and
if declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the 20th day of April, July,
October and January, in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series C Junior Participating Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $3.00 or (b) the Adjustment
Number (as defined below) times the aggregate per share amount of all cash
dividends, and the Adjustment Number times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock, par value $1.00 per share, of the Corporation (the "Common
Stock") since the immediately preceding Quarterly Dividend Payment Date, or,
with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series C Junior Participating
Preferred Stock.  The "Adjustment Number" shall initially be 1000.  In the
event the Corporation shall at any time after July 17, 1996 (the "Rights
Declaration Date") (i) declare and pay any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     (B) The Corporation shall declare a dividend or distribution on the Series
C Junior Participating Preferred Stock as provided in paragraph (A) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock).

     (C)   Dividends shall begin to accrue and be cumulative on outstanding
shares of Series C Junior Participating Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares of Series
C Junior Participating Preferred Stock, unless the date of issue of such shares
is prior to the record date for the first Quarterly Dividend Payment Date, in
which case dividends on such shares shall begin to accrue from the date of
issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of
holders of shares of Series C Junior Participating Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly 


                                      2



   3

Dividend Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Quarterly Dividend Payment Date.  Accrued
but unpaid dividends shall not bear interest.  Dividends paid on the shares of
Series C Junior Participating Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall
be allocated pro rata on a share-by-share basis among all such shares at the
time outstanding.  The Board of Directors may fix a record date for the
determination of holders of shares of Series C Junior Participating Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 60 days prior to the date
fixed for the payment thereof.

     3. Voting Rights.  The holders of shares of Series C Junior Participating
Preferred Stock shall have the following voting rights:

        (A) Each share of Series C Junior Participating Preferred Stock shall
entitle the holder thereof to a number of votes equal to the Adjustment Number
on all matters submitted to a vote of the stockholders of the Corporation.

        (B) Except as required by law and by Section 10 hereof, holders of 
Series C Junior Participating Preferred Stock shall have no special voting
rights and their consent shall not be required (except to the extent they are
entitled to vote with holders of Common Stock as set forth herein) for taking
any corporate action.

     4. Certain Restrictions.

        (A) Whenever quarterly dividends or other dividends or distributions
payable on the Series C Junior Participating Preferred Stock as provided in
Section 2 are in arrears, thereafter and until all accrued and unpaid dividends
and distributions, whether or not declared, on shares of Series C Junior
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not:
             
              (i) declare or pay dividends on, make any other distributions on, 
or redeem or purchase or otherwise acquire for consideration any shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series C Junior Participating Preferred Stock;

             (ii) declare or pay dividends on or make any other distributions on
any shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Series C Junior Participating
Preferred Stock, except dividends paid ratably on the Series C Junior
Participating Preferred Stock and all such parity stock on which dividends
are payable or in arrears in proportion to the total amounts to which the
holders of all such shares are then entitled; or

            (iii) purchase or otherwise acquire for consideration any shares of
Series C Junior Participating Preferred Stock, or any shares of stock ranking
on a parity with the Series 

                                      3



   4


C Junior Participating Preferred Stock, except in accordance with a purchase
offer made in writing or by publication (as determined by the Board of
Directors) to all holders of Series C Junior Participating Preferred Stock, or
to such holders and holders of any such shares ranking on a parity therewith,
upon such terms as the Board of Directors, after consideration of the
respective annual dividend rates and other relative rights and preferences of
the respective series and classes, shall determine in good faith will result in
fair and equitable treatment among the respective series or classes.

        (B) The Corporation shall not permit any subsidiary of the Corporation 
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section
4, purchase or otherwise acquire such shares at such time and in such manner.

     5. Reacquired Shares.  Any shares of Series C Junior Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any
manner whatsoever shall be retired promptly after the acquisition thereof.  All
such shares shall upon their retirement become authorized but unissued shares
of  Preferred Stock and may be reissued as part of a new series of  Preferred
Stock to be created by resolution or resolutions of the Board of Directors,
subject to any conditions and restrictions on issuance set forth herein.

     6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation,
dissolution or winding up of the Corporation, voluntary or otherwise, no
distribution shall be made to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Series C Junior Participating Preferred Stock unless, prior thereto, the
holders of shares of Series C Junior Participating Preferred Stock shall have
received an amount per share (the "Series C Liquidation Preference") equal to
the greater of (i) $100 plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such
payment, or (ii) the Adjustment Number times the per share amount of all cash
and other property to be distributed in respect of the Common Stock upon such
liquidation, dissolution or winding up of the Corporation.

        (B) In the event, however, that there are not sufficient assets 
available to permit payment in full of the Series C Liquidation Preference and
the liquidation preferences of all other classes and series of stock of the
Corporation, if any, that rank on a parity with the Series C Junior     
Participating Preferred Stock in respect thereof, then the assets available for
such distribution shall be distributed ratably to the holders of the Series C   
Junior Participating Preferred Stock and the holders of such parity shares in
proportion to their respective liquidation preferences.

        (C) Neither the merger or consolidation of the Corporation into or with
another corporation nor the merger or consolidation of any other corporation
into or with the Corporation shall be deemed to be a liquidation, dissolution
or winding up of the Corporation within the meaning of this Section 6.



                                      4

     7. Consolidation, Merger, Etc.  In case the Corporation shall enter into
any consolidation, merger, combination or other transaction in which the
outstanding shares of Common Stock are exchanged for or changed into other
stock or securities, cash and/or any other property, then in any such case each
share of Series C Junior Participating Preferred Stock shall at the same time
be similarly exchanged or changed in an amount per share equal to the
Adjustment Number times the aggregate amount of stock, securities, cash and/or
any other property (payable in kind), as the case may be, into which or for
which each share of Common Stock is changed or exchanged.

     8. No Redemption.  Shares of Series C Junior Participating Preferred Stock
shall not be subject to redemption by the Company.

     9. Ranking.  The Series C Junior Participating Preferred Stock shall rank
junior to all other series of the Preferred Stock as to the payment of
dividends and as to the distribution of assets upon liquidation, dissolution or
winding up, unless the terms of any such series shall provide otherwise, and
shall rank senior to the Common Stock as to such matters.

     10. Amendment.  At any time that any shares of Series C Junior
Participating Preferred Stock are outstanding, the Restated Certificate of
Incorporation of the Corporation shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series C Junior Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of two-thirds of the outstanding
shares of Series C Junior Participating Preferred Stock, voting separately as a
class.

     11. Fractional Shares.  Series C Junior Participating Preferred Stock may
be issued in fractions of a share that shall entitle the holder, in proportion
to such holder's fractional shares, to exercise voting rights, receive
dividends, participate in distributions and to have the benefit of all other
rights of holders of Series C Junior Participating Preferred Stock.
