                                     PROSPECTUS
                         64,072 SHARES OF COMMON STOCK OF 
                       CARLINVILLE NATIONAL BANK SHARES, INC.
                                  PROXY STATEMENT
             FOR SPECIAL MEETING OF SHIPMAN BANCORP, INC. STOCKHOLDERS
                          TO BE HELD [____________], 1998
                                          
     This Proxy Statement-Prospectus relates to the consideration of the 
Agreement and Plan of Merger dated March 27, 1998 (the "Merger Agreement"), 
among Carlinville National Bank Shares, Inc., a Delaware corporation ("CNB"), 
Shipman Bancorp, Inc., an Illinois corporation ("Shipman"), and Shipman 
Acquisition Corporation, an Illinois corporation and a wholly-owned 
subsidiary of CNB ("Acquisition Corp"), which is attached to this Proxy 
Statement-Prospectus as Appendix A, which provides for the merger of 
Acquisition Corp into Shipman (the "Merger"), with Shipman becoming a 
wholly-owned subsidiary of CNB, and the payment of cash, the issuance of 
shares of CNB's common stock, $1.00 par value ("CNB Common Stock"), or a 
combination of both to the stockholders of Shipman ("Shipman Stockholders") 
upon the consummation of the Merger. This Proxy Statement-Prospectus is first 
being mailed to Shipman Stockholders on or about [__________], 1998.

     This Proxy Statement-Prospectus is being furnished to Shipman 
Stockholders in connection with the solicitation of proxies by the Board of 
Directors of Shipman for use at a Special Meeting of Stockholders of Shipman 
to be held at [__:__ _.m.], local time, on [__________], 1998, at 
[_______________], and at any adjournments or postponements thereof.

     This Proxy Statement-Prospectus is a prospectus of CNB relating to its 
offering of shares of CNB Common Stock to the Shipman Stockholders who elect 
to receive shares of CNB Common Stock in connection with the proposed Merger. 
 If the Merger Agreement is approved by the requisite vote of Shipman 
Stockholders, and if, following the satisfaction of certain other conditions, 
the Merger is consummated, each issued and outstanding share of Shipman's 
common stock, $10.00 par value ("Shipman Common Stock"), other than those 
held by Shipman Stockholders who exercise their rights as dissenters, will be 
converted into the right to receive cash of $190, or two shares of CNB Common 
Stock, on the terms and subject to the limitations described herein and in 
the Merger Agreement. SEE "THE MERGER."

     Based on:  (i) 32,036 shares of Shipman Common Stock outstanding on 
[____________], 1998, (ii) an exchange ratio of two shares of CNB Common 
Stock for each share of Shipman Common Stock, (iii) the existence of no 
dissenting Shipman Stockholders and (iv) the election by each Shipman 
Stockholder to receive shares of CNB Common Stock and no cash, a maximum of 
approximately 64,072 shares of CNB Common Stock will be issued as a result of 
the Merger, which represents approximately 25.6% percent of the maximum 
number of shares of CNB Common Stock that would be outstanding immediately 
after consummation of the Merger.  The actual number of shares of CNB Common 
Stock to be issued in the Merger will depend upon the number of shares of 
Shipman Common Stock which Shipman Stockholders elect to convert into the 
right to receive shares of CNB Common Stock, the number of shares of Shipman 
Common Stock held by Shipman Stockholders who choose to exercise their right 
to dissent from the Merger, and the resulting fractional shares of Shipman 
Common Stock for which cash will be paid at the per share price of $190 per 
share.  The number of shares of CNB Common Stock indicated at the top of this 
page is the maximum number of shares of CNB Common Stock that is currently 
estimated to be issued in the Merger.

                                     THE MERGER

     The Shipman Stockholders are each being asked to consider and vote upon 
a proposal to approve and adopt the Merger Agreement, pursuant to which 
Acquisition Corp will be merged with and into Shipman, with Shipman being the 
surviving entity and becoming a wholly-owned subsidiary of CNB.  Following 
the consummation of the Merger, all of the outstanding shares of Shipman 
Common Stock, other than shares for which dissenters' rights have been 
perfected, will be converted into the right to receive the Merger 
Consideration, as defined below.  It is not necessary for the stockholders of 
CNB to approve the Merger Agreement, and CNB, as the sole stockholder of 
Acquisition Corp, has previously approved the Merger Agreement.  SEE "THE 
MERGER--GENERAL."

                                MERGER CONSIDERATION

     Each of the Shipman's stockholders is entitled under the terms and 
subject to the limitations set forth in the Merger Agreement to elect to 
receive for the shares of Shipman Common Stock held by them either shares of 
CNB Common Stock at the rate of two shares of CNB Common Stock for each share 
of Shipman Common Stock, or cash in the amount of $190 per share, or with 
respect to all of his or her shares, a combination of shares of CNB Common 
and cash (the "Merger Consideration").  Shipman has represented in the Merger 
Agreement that the maximum number of shares of Shipman Common Stock that will 
be outstanding at the Effective Time will be 32,036 shares.  No fractional 
shares will be issued and CNB will pay cash at the rate of $190 per share of 
Shipman Common Stock for any fractional share interests resulting from the 
Merger.

     The Merger Agreement provides that no greater than 30% of the 
outstanding shares of Shipman Common Stock can be converted into the right to 
receive cash. If holders of greater than 30% of the outstanding shares of 
Shipman Common Stock elect to receive cash, then an adjustment will be made 
pursuant to the Merger Agreement that will reduce the number of shares of 
Shipman Common Stock to be converted into the right to receive cash to the 
30% required level, with such excess shares being converted to the right to 
receive CNB Common Stock.  The Merger Agreement contains no limit on the 
number of shares that may be converted into the right to receive shares of 
CNB Common Stock.

     There is no trading market for the shares of CNB Common Stock.  Based 
solely, however, on the cash price of $190 per share of Shipman Common Stock, 
the market value of the merger consideration to be received by Shipman 
Stockholders would be $190 per share of Shipman Common Stock.

         REASONS FOR THE MERGER; RECOMMENDATIONS OF THE BOARDS OF DIRECTORS

     SHIPMAN.  The Shipman Board of Directors (the "Shipman Board") has 
unanimously approved and adopted the Merger Agreement and the transactions 
contemplated thereby and has determined that the Merger is fair to, and in 
the best interests of, Shipman and the Shipman Stockholders.  THE SHIPMAN 
BOARD THEREFORE RECOMMENDS A VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

     For a discussion of the factors considered by the Shipman Board in 
reaching its decision to approve the Merger Agreement and the transactions 
contemplated thereby, SEE "THE MERGER--BACKGROUND OF AND REASONS FOR THE 
MERGER - SHIPMAN BOARD'S REASONS FOR THE MERGER."

     CNB.  The CNB Board of Directors (the "CNB Board") has unanimously 
approved and adopted the Merger Agreement and the transactions contemplated 
thereby and has determined that the Merger and the issuance of the shares of 
CNB Common Stock pursuant thereto are fair to, and in the best interests of, 
CNB and its stockholders.

contemplated thereby, SEE "THE MERGER--BACKGROUND OF AND REASONS FOR THE 
MERGER - CNB BOARD'S REASONS FOR THE MERGER."

                        OPINION OF SHIPMAN FINANCIAL ADVISOR

     Shipman has retained Southard Financial ("Southard") as its financial 
advisor in connection with the transactions contemplated by the Merger 
Agreement and to evaluate the financial terms of the Merger.  SEE "THE MERGER 
- --BACKGROUND OF AND REASONS FOR THE MERGER - SHIPMAN BOARD'S REASONS FOR THE 
MERGER."

     On January 2, 1998, Southard delivered its preliminary indication to the 
Shipman Board that, as of such date, the Merger Consideration to be paid by 
CNB pursuant to the Merger Agreement was fair from a financial point of view 
to the Shipman Stockholders.  Southard subsequently confirmed its earlier 
preliminary indication by delivery of its written opinion dated June 23, 1998.

     The full text of the written opinion of Southard, dated June 23, 1998, 
which sets forth assumptions made, matters considered and limitations on the 
review undertaken in connection with the opinion, is attached hereto as 
Appendix B and is incorporated herein by reference.  SHIPMAN STOCKHOLDERS ARE 
URGED TO, AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY.  SEE "THE 
MERGER--OPINION OF SHIPMAN FINANCIAL ADVISOR."

                            DISSENTERS' APPRAISAL RIGHTS

     Under Illinois law, each of the Shipman Stockholders has dissenters' 
appraisal rights provided such stockholder does not vote in favor of the 
Merger Agreement and complies with certain statutory procedures within the 
time frames specified by the Illinois Business Corporation Act of 1983, as 
amended (the "IBCA").  The value determined in such appraisal could be more 
than, the same as, or less than the value of the Merger Consideration, 
depending upon the results of the statutory appraisal process.  Sections 
11.65 and 11.70 of the IBCA, which contain the provisions relating to 
dissenters' appraisal rights, are set forth on Appendix C to this Proxy 
Statement-Prospectus.  IT IS A CONDITION TO CNB'S OBLIGATION TO CONSUMMATE 
THE MERGER THAT DISSENTERS' APPRAISAL RIGHTS NOT BE PERFECTED WITH RESPECT TO 
MORE THAN 10% OF THE OUTSTANDING SHARES OF SHIPMAN COMMON STOCK.  SEE "THE 
MERGER--DISSENTERS' APPRAISAL RIGHTS" and "COMPARISON OF THE RIGHTS OF CNB 
STOCKHOLDERS AND SHIPMAN STOCKHOLDERS --DISSENTERS' APPRAISAL RIGHTS."

                            EFFECTIVE TIME; CLOSING DATE

     The effective time of the Merger will be as of the close of business as 
of the day on which a Certificate of Merger is issued by the Secretary of 
State of Illinois (the "Effective Time"), which will occur only after receipt 
of all regulatory approvals and the approval of the Merger Agreement by the 
Shipman Stockholders and the satisfaction or waiver of all other conditions 
to the Merger.  The closing of the Merger (the "Closing") will take place on 
a date mutually agreed upon by CNB and Shipman (the "Closing Date").  In the 
absence of such agreement, the Closing shall be held on the fifth business 
day after the first date on which all required regulatory approvals and the 
approval of the Shipman Stockholders have been received.  SEE "THE 
MERGER--EFFECTIVE TIME; CLOSING DATE."

                     INTERESTS OF CERTAIN PERSONS IN THE MERGER

     Certain members of Shipman's management and the Shipman Board may be deemed
to have certain interests in the Merger in addition to their interests as
Shipman Stockholders generally.  These material interests include, among others,
provisions in the Merger Agreement relating to indemnification, maintenance of
director and officer liability insurance coverage and the appointment of

                                       7

<PAGE>

one member of the Shipman Board, James H. Frank, to the CNB Board following 
the consummation of the Merger.  CNB has also agreed that not less than two 
nor more than four of the current directors of Citizens Bank will be retained 
by CNB after the Effective Time as directors of Citizens Bank.

     The Shipman Board was aware of all of the interests described above and 
considered them, among other matters, in approving the Merger Agreement and 
the transactions contemplated thereby. SEE "THE MERGER--INTERESTS OF CERTAIN 
PERSONS IN THE MERGER."

                                REGULATORY APPROVALS

     The Merger is subject to the approval of the Board of Governors of the 
Federal Reserve System (the "Federal Reserve") and the Illinois Commissioner 
of Banks and Real Estate (the "Illinois Commissioner").  CNB filed 
applications for approval of the Merger with the Federal Reserve and the 
Illinois Commissioner on June 10, 1998.  CNB anticipates obtaining the 
approval of the Federal Reserve and the Illinois Commissioner during the 
third quarter of 1998.  There can be no assurance as to the timing of such 
approvals or that the Federal Reserve and the Illinois Commissioner will 
approve the Merger.

     It is a condition to the consummation of the Merger that the Federal 
Reserve and Illinois Commissioner approvals not contain any non-standard 
conditions or restrictions.  If CNB reasonably determines that any such 
non-standard conditions or restrictions would be unduly burdensome to CNB or 
its subsidiaries, CNB will not be obligated to consummate the Merger.  There 
can be no assurance that the Federal Reserve approval or the Illinois 
Commissioner approval will not contain conditions or restrictions which cause 
such approval to fail to satisfy such conditions to the consummation of the 
Merger.  SEE "THE MERGER--CONDITIONS TO THE MERGER" and "--REGULATORY 
APPROVALS."

                              CONDITIONS TO THE MERGER

     The respective obligations of the parties to consummate the Merger are 
subject to the fulfillment or waiver of certain conditions specified in the 
Merger Agreement.  These include, among other things, the receipt of the 
requisite regulatory approvals and the approval of the Shipman Stockholders, 
the accuracy of the representations and warranties contained therein, the 
performance of all obligations imposed thereby, the receipt by Shipman of a 
certain tax opinion, the continued effectiveness without material 
modification of the opinion of Shipman's financial advisor and certain other 
conditions customary in transactions of this nature.  There can be no 
assurance as to when and if such conditions will be satisfied or waived or 
that the Merger will be consummated.  SEE "THE MERGER--CONDITIONS TO THE 
MERGER."

                         WAIVER AND AMENDMENT; TERMINATION

     Prior to the Effective Time, the CNB and Shipman Boards may extend the 
time for performance of any obligations under the Merger Agreement, waive any 
inaccuracies in the representations and warranties contained in the Merger 
Agreement and waive compliance with any agreements or conditions contained in 
the Merger Agreement.  Subject to applicable law, the Merger Agreement may be 
amended by action of the CNB and Shipman Boards at any time before or after 
approval of the Merger Agreement by the Shipman Stockholders.  SEE "THE 
MERGER--WAIVER AND AMENDMENT; TERMINATION."

     The Merger Agreement may be terminated at any time prior to the 
Effective Time by the mutual agreement of the parties.  In addition, the 
Merger Agreement may be terminated at any time prior to the Effective Time:  
(i) by a non-breaching party, if a party commits a material breach of the 
Merger Agreement; (ii) by the party for whose benefit a Closing condition 
exists, if the Closing condition has not been satisfied as of the Closing 
Date, or if satisfaction of such condition becomes impossible (other than due 
to the failure of a party for whose benefit the Closing condition exists to 

                                       8

<PAGE>

comply with its obligations under the Merger Agreement) and such condition is 
not waived by the Closing Date by the party for whose benefit such condition 
exists; or (iii) by either party, if the Closing has not occurred (other than 
through the failure of the party seeking to terminate the Merger Agreement to 
comply fully with its obligations under the Merger Agreement) by January 27, 
1999 (SEE "THE MERGER--WAIVER AND AMENDMENT; TERMINATION").

                       CONDUCT OF BUSINESS PENDING THE MERGER

     Each of CNB and Shipman has agreed to conduct its business prior to the 
Effective Time in accordance with certain guidelines set forth in the Merger 
Agreement.  SEE "THE MERGER--BUSINESS PENDING THE MERGER AND OTHER COVENANTS."

                   FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     It is a condition to the obligation of Shipman to consummate the Merger 
that Shipman shall have received an opinion of Cummings & Associates, P.C., 
accountants for CNB and Shipman ("Cummings"), to the effect that the Merger 
will be treated as a reorganization within the meaning of Section 368(a) of 
the Internal Revenue Code of 1986, as amended (the "Code"), and that for 
federal income tax purposes no gain or loss will be recognized by Shipman as 
a result of the Merger, and, accordingly, for federal income tax purposes, no 
gain or loss will be recognized by any Shipman Stockholder upon receipt 
solely of CNB Common Stock, pursuant to the Merger (except with respect to 
any cash Merger Consideration or cash in lieu of a fractional shares interest 
in CNB Common Stock received by a Shipman Stockholder or as the result of the 
exercise of dissenter's appraisal rights).

     BECAUSE CERTAIN TAX CONSEQUENCES MAY VARY DEPENDING UPON THE PARTICULAR 
CIRCUMSTANCES OF A SHIPMAN STOCKHOLDER, SUCH STOCKHOLDERS ARE URGED TO 
CONSULT THEIR TAX ADVISORS CONCERNING THE SPECIFIC TAX CONSEQUENCES TO THEM 
OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF VARIOUS STATE, LOCAL 
AND FOREIGN TAX LAWS.  SEE "THE MERGER--FEDERAL INCOME TAX CONSEQUENCES OF 
THE MERGER" and "-- CONDITIONS TO THE MERGER."

                            RESALES OF CNB COMMON STOCK

     The shares of CNB Common Stock into which shares of Shipman Common Stock 
are converted at the Effective Time will be freely transferable, except for 
the shares issued to "Affiliates" (as defined by Rule 145 of the Rules and 
Regulations of the Commission) of Shipman in connection with the Merger.  The 
shares to be issued to such Affiliates may only be sold:  (i) under a 
separate registration for distribution (which CNB has not agreed to provide); 
(ii) pursuant to Rule 145 under the Securities Act of 1933, as amended; or 
(iii) pursuant to another exemption from registration. SEE "THE 
MERGER--RESALE OF CNB COMMON STOCK."

              EFFECTS OF THE MERGER ON RIGHTS OF SHIPMAN STOCKHOLDERS

     As a result of the Merger, Shipman Stockholders may elect to become 
stockholders of CNB ("CNB Stockholders").  For a comparison of the charter, 
bylaw and corporate law provisions governing the rights of CNB Stockholders 
and Shipman Stockholders, SEE "COMPARISON OF THE RIGHTS OF CNB STOCKHOLDERS 
AND SHIPMAN STOCKHOLDERS."

                        COMPARATIVE PER COMMON SHARE DATA

     The following table sets forth, for the periods presented, selected 
unaudited, historical per common share data for CNB Common Stock and Shipman 
Common Stock on a historical and pro forma combined basis and for Shipman 
Common Stock on a pro forma equivalent basis after giving effect to the 
Merger and assuming the exchange ratio of two shares of CNB Common Stock for 
each share of Shipman Common Stock and also that:  (i) holders of 70% of the 
issued and outstanding Shipman Common Stock elect to receive CNB Common 
Stock; or (ii) holders of 100% of the issued and outstanding Shipman Common 
Stock elect to receive CNB Common Stock.

     The pro forma combined information is not necessarily indicative of the 
actual results that would have occurred had the Merger been consummated prior 
to the periods indicated, or of the future operations of the combined entity. 
 The data presented is based upon, and is qualified in its entirety by, the 
historical consolidated financial statements and related notes of CNB and 
Shipman and the pro forma condensed combining financial statements 
(unaudited) included elsewhere herein and should be read in conjunction 
therewith.  The assumptions used in the preparation of this table are 
included in "Notes to Pro Forma Condensed Combining Financial Statements."

                                   SPECIAL MEETING


PLACE, TIME, DATE AND RECORD DATE

     The Special Meeting will be held at [__:__ _.m.], local time, on 
[__________], 1998, at [_______________].  This Proxy Statement-Prospectus is 
being sent to Shipman Stockholders and accompanies a form of proxy (the 
"Shipman Proxy") which is being solicited by the Shipman Board for use at the 
Special Meeting.  Only holders of record of shares of Shipman Common Stock at 
the close of business on the Record Date are entitled to notice of, and to 
vote at, the Special Meeting. 

MATTERS TO BE CONSIDERED

     At the Special Meeting, Shipman Stockholders will vote on the approval 
and adoption of the Merger Agreement and the transactions contemplated 
thereby, including the Merger of Acquisition Corp with and into Shipman and 
the conversion of each share of Shipman Common Stock into two shares of CNB 
Common Stock or cash in the amount of $190 per share upon the consummation of 
the Merger.  Stockholders will also consider and vote upon such other matters 
as may properly be brought before the Special Meeting.  As of the date 
hereof, the Shipman Board knows of no business that will be presented for 
consideration at the Special Meeting other than the matters described in this 
Proxy Statement-Prospectus.

VOTE REQUIRED

     The affirmative vote of the holders of not less than two thirds of the 
outstanding shares of Shipman Common Stock is required for approval of the 
Merger Agreement.  As of the Record Date, there were 32,036 shares of Shipman 
Common Stock issued and outstanding and entitled to be voted at the Special 
Meeting.  Therefore, the affirmative vote of holders of at least 21,358 
shares of Shipman Common Stock is required for approval of the Merger 
Agreement. Abstentions and broker non-votes will have the same effect as 
votes against this proposal. 

     Each holder of record of shares of Shipman Common Stock on the Record 
Date will be entitled to cast one vote per share on the Merger Agreement at 
the Special Meeting.  Such vote may be exercised in person or by properly 
executed proxy.  The presence, in person or by properly executed proxy, of 
the holders of a majority of the outstanding shares of Shipman Common Stock 
entitled to vote at the Special Meeting is necessary to constitute a quorum.  
With a quorum, or in the absence of such, the affirmative vote of the 
majority of shares of Shipman Common Stock represented at the Special Meeting 
may authorize adjournment of the meeting.  Shares of Shipman Common Stock 
represented by properly executed proxies which are to be voted against the 
Merger Agreement will not be voted for the adjournment of the Special 
Meeting.  Abstentions and broker non-votes will be treated as shares present 
at the Special Meeting for purposes of determining the presence of a quorum.

     Approval of the Merger Agreement by the Shipman Stockholders is a 
condition to, and required for, consummation of the Merger.  SEE "THE 
MERGER--CONDITIONS TO THE MERGER."  

PROXIES

     Shares of Shipman Common Stock represented by a properly executed proxy 
received prior to or at the Special Meeting will, unless such proxy has been 
revoked, be voted at the Special Meeting and any adjournments or 
postponements thereof, in accordance with the instructions indicated in such 
proxy.  If no instructions are indicated on a properly executed Shipman 
Proxy, the shares will be voted FOR the Merger Agreement. 

     Any Shipman Proxy given pursuant to this solicitation or otherwise may 
be revoked by the person giving it at any time before it is voted either: (i) 
by delivering to the Secretary of Shipman at 111 Keating Street, Shipman, 
Illinois 62685 on or before the taking of the vote at the Special Meeting, a 
written notice of revocation bearing a later date than the date of the 
Shipman Proxy or a later dated proxy relating to the same shares or (ii) by 
attending the Special Meeting and voting in person.  Attendance at the 
Special Meeting will not in itself constitute the revocation of a proxy.

GENERAL

     Pursuant to the Merger Agreement, Acquisition Corp will be merged with 
and into Shipman, with Shipman being the surviving entity and a wholly-owned 
subsidiary of CNB.  As soon as possible after the conditions to consummation 
of the Merger described below have been satisfied or waived, and unless the 
Merger Agreement has been terminated as provided below, CNB and Shipman will 
file Articles of Merger with the Secretary of State of the State of Illinois 
with respect to the Merger.  The Merger will become effective upon the close 
of business on the day when a Certificate of Merger has been issued by the 
Secretary of State of the State of Illinois.  It is presently contemplated 
that the Effective Time will be as soon as practicable following the 
fulfillment or waiver of each of the conditions to the Merger.  SEE 
"--EFFECTIVE TIME; CLOSING DATE," "--CONDITIONS TO THE MERGER" and "--WAIVER 
AND AMENDMENT; TERMINATION."

     Upon consummation of the Merger, the Shipman Stockholders will be 
entitled to receive the Merger Consideration (as defined herein) in 
consideration for their shares of Shipman Common Stock and thereupon shall 
cease to be Shipman Stockholders, Acquisition Corp will be merged into 
Shipman and cease to exist and Shipman will exist as a wholly-owned 
subsidiary of CNB. 

MERGER CONSIDERATION
     
     Subject to the terms, conditions and procedures set forth in the Merger 
Agreement, each share of Shipman Common Stock issued and outstanding 
immediately prior to the consummation of the Merger (except shares for which 
Shipman Stockholders have perfected dissenters' appraisal rights) will be 
converted into the right to receive 

                                       15

<PAGE>

cash, two shares of CNB Common Stock or a combination of cash and shares of 
CNB Common Stock.  For his or her shares of Shipman Common Stock, each holder 
thereof will be entitled to:  (i) elect to receive cash for all of such 
shares at the rate of $190 per share ("Cash Election"); (ii) elect to receive 
CNB Common Stock for all of such shares at the rate of two shares of CNB 
Common Stock for each share of Shipman Common Stock ("Stock Election"); (iii) 
elect to receive CNB Common Stock for a stated percentage of such shares 
("Partial Stock Election") and to receive cash for a stated percentage of 
such shares ("Partial Cash Election"); or (iv) indicate by such holder's 
action or inaction that he or she has no preferences as to the receipt of 
cash or CNB Common Stock for such shares ("Non-Election").

     The Merger Agreement provides that the exchange ratio of two shares of 
CNB Common Stock for each share of Shipman Common Stock will be appropriately 
adjusted in the event of any split, combination, stock dividend or stock 
distribution with respect to shares of CNB Common Stock effected by CNB prior 
to the Effective Time.  The Merger Agreement does not provide for any 
adjustment of the cash portion of the Merger Consideration.

     Notwithstanding any elections made by Shipman Stockholders, the Merger 
Agreement provides that the sum of: (i) the number of shares of Shipman 
Common Stock to be converted into the right to receive cash, plus (ii) the 
number of Dissenting Shares (as defined below), cannot be more than 30% of 
the number of issued and outstanding shares of Shipman Common Stock 
immediately prior to the Effective Time (the "Maximum Cash Payment Number"). 
The Merger Agreement contains no limit on the number of shares of Shipman 
Common Stock that may be converted into the right to receive shares of CNB 
Common Stock.  If the number of shares of Shipman Common Stock for which a 
Cash Election or a Partial Cash Election was made (collectively, the "Cash 
Election Shares"), plus the number of Dissenting Shares, exceeds the Maximum 
Cash Payment Number, then the consideration to be received by Shipman 
Stockholders who have made a Cash Election or a Partial Cash Election will be 
adjusted in the manner provided below.

     If the number of Cash Election Shares, plus the number of Dissenting 
Shares, exceeds the Maximum Cash Payment Number, all shares of Shipman Common 
Stock for which a Stock Election or a Partial Stock Election were made 
(collectively, the "Stock Election Shares") will be converted into the right 
to receive CNB Common Stock, and the Cash Election Shares will be converted 
into the right to receive CNB Common Stock and cash in the following manner.  
Each Cash Election Share shall be converted into the right to receive:

          (i)  an amount in cash (rounded to the nearest cent), without 
     interest, equal to the product of (A) the Cash Price Per Share and (B) a 
     fraction ("Cash Fraction"), the numerator of which shall be the Maximum 
     Cash Payment Number and the denominator of which shall be the sum of the 
     Cash Election Shares plus the Dissenting Shares; and

          (ii) a number of shares of CNB Common Stock equal to the product 
     of:  (A) two (2); multiplied by (B) a fraction equal to one (1) minus 
     the Cash Fraction.

     If the Cash Election Shares, plus the number of Dissenting Shares, is 
less than the Maximum Cash Payment Number, then each Cash Election Share 
shall be converted into the right to receive the Cash Price Per Share.  The 
Merger Agreement further provides that each Non-Election will be treated as a 
Stock Election.
     
     Shipman has represented in the Merger Agreement that the maximum number 
of shares of Shipman Common Stock that will be outstanding at the Effective 
Time will be 32,036 shares.  No fractional shares will be issued and CNB will 
pay cash at the rate of $190 per share of Shipman Common Stock for any 
fractional share interests resulting from the Merger.

     There is no trading market for the shares of CNB Common Stock.  Based 
solely, however, on the cash price of $190 per share of Shipman Common Stock, 
the market value of the merger consideration to be received by Shipman 
Stockholders would be $190 per share of Shipman Common Stock.

BACKGROUND OF AND REASONS FOR THE MERGER

     BACKGROUND OF THE MERGER.  During the spring of 1997, Shipman received 
an unsolicited offer for an acquisition of Shipman and its wholly-owned 
subsidiary, Citizens State Bank.  The Board reviewed the unsolicited offer 
and after consultation with independent third parties, rejected the offer as 
being inadequate.  At approximately the same time, the Board of Directors 
obtained an appraisal of the value of Shipman.

     During the summer and late fall of 1997, the Board consulted with 
outside experts as to whether Shipman should remain independent or be offered 
for sale. Numerous issues, including aging of the shareholder base, the lack 
of management succession and the difficulties in competing with some of the 
larger institutions, all favored approaching the market to determine at least 
the price that Shipman would bring.  In July of 1997, the Board engaged the 
firm of Gerrish & McCreary, P.C. to assist the Bank in marketing the 
institution. Approximately 17 institutions were contacted and 16 packages 
distributed. Shipman received nine bids, of which CNB's was the highest.

     The Board determined to allow the four highest bidding groups to perform 
a due diligence review and requested that they re-bid.  CNB remained the 
highest bidder.  Upon further negotiation, the Merger Agreement was executed 
on March 27, 1998.

     SHIPMAN BOARD'S REASONS FOR THE MERGER.  After careful study and 
evaluation, the Shipman Board has unanimously approved the Merger Agreement 
and has determined that the Merger is fair to, and in the best interests of, 
Shipman and the Shipman Stockholders.  The Shipman Board believes that the 
Merger will enable Shipman Stockholders to realize significant value on their 
investment and also will enable them to participate in opportunities for 
growth that Shipman believes the Merger makes possible.

     In reaching its determination that the Merger is fair to, and in the 
best interests of, Shipman and its Stockholders, the Shipman Board carefully 
considered a variety of factors with the assistance of its legal and 
financial advisors. Among the factors it considered were the following:

          (a)  Shipman considered its business, financial condition, results 
     of operations and prospects, including, but not limited to, its 
     potential growth, development, productivity and profitability were it to 
     remain independent.  In the Shipman Board's opinion, a business 
     combination with a larger bank holding company such as CNB would provide 
     both greater short-term and long-term value to Shipman Stockholders than 
     other alternatives available.  Such a business combination would enhance 
     Shipman's competitiveness and its ability to serve its depositors, 
     customers and the communities in which it operates.  The increased 
     competitive advantage would result primarily from the ability of Shipman 
     to offer new and enhanced products and services already developed and 
     tested by CNB, the cost savings from combining operations and support 
     functions, and the increased access to capital that CNB could provide.  
     Such an increased competitive advantage would be likely to result in an 
     increase in the value of CNB Common Stock that will be received by 
     Shipman Stockholders.

          (b)  The current and prospective environments in which Shipman 
     operates, including national and local economic conditions, the current 
     regulatory environment and the trend toward consolidation in the 
     financial services industry generally and in Shipman's local market, 
     specifically, were also factors in the Shipman Board's decision.  The 
     increases in competition, together with increased bank regulatory 
     reporting and other requirements, have made it more difficult for 
     independent community banks to compete with the banking affiliates of 
     larger institutions with respect to the range of products and services 
     offered and the costs at which such products and services can be 
     offered.  CNB's philosophy of relationship banking and allowing each of 
     its banking centers to continue to operate as community banks within 
     their own local markets, focusing on servicing the needs of their 
     particular communities, should provide an opportunity for Shipman to 
     compete more effectively with larger institutions but still maintain its 
     community banking approach.  This compatibility of businesses and 
     management philosophies of Shipman and CNB constituted a significant 
     additional factor in the Shipman Board's decision.

          (c)  The strategic, competitive advantage that CNB will have 
     through its combination with Shipman was considered by the Shipman 
     Board.  As a result of the Merger, CNB will have a significant 

                                       17

<PAGE>

     presence in central and southwestern Illinois, thereby enhancing the 
     value of CNB's franchise and the potential value to Shipman Stockholders.

          (d)  The Shipman Board considered the business, results of 
     operations, financial condition and asset quality of CNB, as well as its 
     future growth prospects following the Merger.  The Merger presents an 
     opportunity for potential synergies and cost savings by integrating the 
     responsibilities for functions such as the following: product 
     development; training in product sales and services which CNB has had in 
     place for several years; internal audit, loan review and compliance 
     training; and stockholder record keeping and communications.  CNB's 
     established operational and training systems are expected to result in 
     cost savings from economies of scale as well as being able to provide 
     Shipman employees with a higher level of training to meet customer needs.

          (e)  Based upon the financial terms of other recent business 
     combinations in the financial services industry and information 
     concerning the business, financial condition, results of operations and 
     prospects of CNB, the Shipman Board solicited an opinion from Southard 
     regarding the fairness of the Merger Consideration, from a financial 
     point of view, to the Shipman Stockholders. Based upon the opinion of 
     Southard, the anticipated tax free nature of the Merger for Federal 
     income tax purposes to Shipman Stockholders (to the extent Shipman 
     Stockholders receive CNB Common Stock), and the likelihood that the 
     proposed transaction would be consummated, the Shipman Board determined 
     that the Merger was preferable to other alternatives available to 
     Shipman, such as being acquired by a different company or remaining 
     independent and growing internally.

     While each member of the Shipman Board individually evaluated each of 
the foregoing as well as other factors, the Shipman Board collectively did 
not assign any specific or relative weights to the factors considered and did 
not make any determination with respect to any individual factor.  The 
Shipman Board collectively made its determination with respect to the Merger 
based on the unanimous conclusion reached by its members that the Merger, in 
light of the factors that each director, individually, considered as 
appropriate, is fair and in the best interests of the Shipman Stockholders.

     In approving the Merger, the Shipman Board was aware that: (i) the 
Merger Agreement contains certain provisions prohibiting Shipman from 
soliciting, facilitating or accepting other offers or agreements to acquire 
Shipman and (ii) Shipman would be liable for the payment to CNB of $200,000 
in certain circumstances generally relating to the breach of the Merger 
Agreement by Shipman and within 24 months of such termination a change in the 
ownership of Shipman.  However, the Shipman Board was also aware that such 
terms were specifically bargained for and insisted upon by CNB as inducements 
to enter into the Merger Agreement.  In addition, in connection with its 
approval of the proposed Merger, the Shipman Board was advised by Southard 
that the indicated value of the Merger: (i) exceeded the upper end of 
Southard's range of estimates of Shipman's stand-alone value and (ii) was at 
the upper end of Southard's range of estimates of Shipman's likely value in 
an acquisition transaction.  In presenting this advice, Southard stated that 
these findings were necessarily based upon economic, market, monetary and 
other conditions as they existed and could be evaluated at the time, 
represented its best business judgment under the circumstances and should not 
be construed in any way as a financial fairness or other form of expert 
opinion.  Southard's fairness opinion is described below and is included as 
Appendix B to this Proxy Statement-Prospectus.  See "--OPINION OF SHIPMAN 
FINANCIAL ADVISOR."

    CNB BOARD'S REASONS FOR THE MERGER.  CNB's strategy for increasing 
long-term value for CNB Stockholders has been to build a banking organization 
primarily focused on the central and southwestern Illinois banking market 
(comprised of the Illinois counties of Macoupin, Christian, Montgomery and 
Sangamon) that continuously gains efficiency, spreads costs over a growing 
asset base and provides innovative products and services over a growing 
customer base. 

     By acquiring Shipman, CNB will significantly expand its operations in 
the southern portion of Macoupin County, Illinois.  Shipman currently 
operates two offices in this area and offers CNB the opportunity to expand 
into the growing St. Louis metropolitan area.  Following the consummation of 
the Merger, CNB will operate seven offices in central and southwestern 
Illinois.  The acquisition of Shipman is consistent with CNB's strategy of 
focusing its growth primarily on this area of Illinois.

                                       18

<PAGE>

     The CNB Board believes that the Merger and the Merger Consideration is 
fair to, and in the best interests of, CNB and its stockholders.  
Accordingly, the CNB Board has unanimously approved the Merger Agreement.

     In negotiating the terms of the Merger, the CNB Board considered a 
number of factors including, without limitation, the following:

           (a)  The Merger Consideration to be paid to the Shipman 
     Stockholders in relation to the market value, book value, earnings per 
     share and dividend rates of the CNB Common Stock and Shipman Common 
     Stock.

          (b)  The CNB Board's review, based in part on a presentation by CNB 
     management with respect to such management's due diligence review of 
     Shipman, of the business, operations and financial condition of Shipman, 
     the prospects of the combined institution and the increased market 
     presence, economies of scale, cost savings opportunities and enhanced 
     opportunities for growth made possible by the Merger; in this regard, 
     the CNB Board noted that the combined institution would have a 
     significantly increased presence in southern Macoupin County with the 
     opportunity to expand into the metropolitan St. Louis area.  The CNB 
     Board took into account that there would be some dilution in 1998 
     earnings per share before the Merger would have an expected accretive 
     effect in subsequent years, and there would be some dilution to the 
     book-value per share of the CNB Common Stock.

          (c)  The short-term and long-term impact the Merger is anticipated 
     to have on CNB's consolidated results of operations, including 
     anticipated cost savings resulting from consolidation in certain areas.

          (d)  The impact of the Merger on depositors, employees, customers 
     and communities served by CNB and Shipman.

          (e)  The terms of the Merger Agreement and the other documents 
     executed in connection with the Merger. 

          (f)  The effectiveness of the Merger as a method of implementing 
     and accelerating CNB's strategy for long-term growth and enhanced 
     stockholder value. This included: (i) the strong Citizens Bank franchise 
     with its loyal customer base in southern Macoupin County, (ii) the fact 
     that the Shipman franchise overlaps with CNB's Macoupin County banking 
     franchise, (iii) an opportunity for additional acquisitions that could 
     be negotiated by a company with CNB's post-merger market capitalization, 
     (iv) an experienced group of Shipman employees with similar approaches 
     to customer service, credit quality, expense reduction and growth and 
     (v) opportunities to leverage capacity in technology over a larger asset 
     and customer base and to realize other additional expense savings.

          (g)  The likelihood of the Merger being approved by the appropriate 
     regulatory authorities.  See "--REGULATORY APPROVALS."

     In view of the wide variety of factors considered in connection with its
evaluation of the Merger, the CNB Board did not find it practicable to, and did
not quantify or otherwise attempt to, assign relative weights to the specific
factors considered in reaching its determination.

RECOMMENDATION OF THE SHIPMAN BOARD
     
      The Shipman Board of Directors has unanimously approved and adopted the 
Merger Agreement and the transactions contemplated thereby and has determined 
that the Merger is fair to, and in the best interests of, Shipman and its 
stockholders. THE SHIPMAN BOARD UNANIMOUSLY RECOMMENDS THAT SHIPMAN 
STOCKHOLDERS VOTE FOR THE PROPOSAL TO APPROVE THE MERGER AGREEMENT.

OPINION OF SHIPMAN FINANCIAL ADVISOR
     
     Shipman retained Southard Financial, a Memphis, Tennessee financial
valuation consulting 

                                       19

<PAGE>

firm, to render its opinion as to the fairness from a financial point of view 
to the holders of Shipman Common Stock of the consideration to be paid in the 
Merger.  In connection with this engagement, Southard Financial evaluated the 
financial terms of the Merger, but was not asked to, and did not recommend 
the exchange ratio formula between CNB and Shipman's respective Common Stocks 
and did not assist in the Merger negotiations.  The exchange ratio formula 
was determined by CNB and Shipman after arm's length negotiations. Shipman 
did not place any limitations on the scope of Southard Financial's 
investigation or review.

     Southard Financial provided the Shipman Board with a fairness opinion 
letter and supporting documentation.  The full text of that fairness opinion 
letter, dated June 23, 1998, which sets forth certain assumptions made, 
matters considered and limitations on the review performed is attached as 
Appendix B and is incorporated herein by reference. The summary of the 
opinion of Southard Financial set forth in this Proxy Statement-Prospectus is 
qualified in its entirety by reference to the full text of the opinion.  
Southard Financial's opinion is addressed to the Shipman Board and does not 
constitute a recommendation to any stockholder of Shipman as to how such 
stockholder should vote at the Special Meeting.

     In arriving at its opinion, Southard Financial conducted interviews with 
officers of CNB and Shipman and reviewed the documents indicated in the 
fairness letter.  Southard Financial did not independently verify the 
accuracy and/or the completeness of the financial and other information 
reviewed in rendering its opinion. Southard Financial did not, and was not 
requested to, solicit third party indications of interest in acquiring any or 
all of the assets of Shipman.

     In connection with rendering its opinion, Southard Financial performed a 
variety of financial analyses which are summarized below.  Southard Financial 
believes that its analyses must be considered as a whole and that considering 
only selected factors could create an incomplete view of the analyses and the 
process underlying the opinion.  In its analyses, Southard Financial made 
numerous assumptions, many of which are beyond the control of Shipman and 
CNB. Any estimates contained in the analyses prepared by Southard Financial 
are not necessarily indicative of future results or values, which may vary 
significantly from such estimates.  Estimates of value of companies do not 
purport to be appraisals or necessarily reflect the prices at which companies 
or their securities may actually be sold.  None of the analyses performed by 
Southard Financial was assigned a greater significance than any other.

ADEQUACY OF TOTAL PRICE

     The key consideration in the fairness opinion was the adequacy of the 
total price paid by CNB.  Under the terms of the merger, Shipman stockholders 
may elect to (1) receive cash of $190 per Shipman share, or (2) receive two 
shares of CNB Common Stock per Shipman share ("the stock option").  The value 
of the transaction for those Shipman stockholders electing the stock option 
is $260 per share, based upon an estimated market value by Southard of CNB 
Common Stock of $130 per share.  The following factors were considered:

     ANALYSIS OF MARKET MERGERS:  Based upon the Merger terms and Shipman 
Stockholders who elect the cash option will receive 132.2% of estimated March 
31, 1998 book value, 21.0 times 1997 earnings, and 12.6% of March 31, 1998 
assets.  Based upon the merger terms and Southard's estimated market value of 
CNB common shares, Shipman Stockholders who elect the stock option will 
receive approximately 181% of estimated March 31, 1998 book value, 28.7 times 
1997 earnings, and 17.3% of March 31, 1998 assets.  Based upon the review 
conducted by Southard Financial, and given the financial characteristics and 
performance of Shipman, the pricing for Shipman in the merger is within the 
range of multiples seen in recent bank acquisitions. 

     DISCOUNTED CASH FLOW ANALYSIS:  Southard Financial estimated the present 
value of the future stream of after-tax cash flow that Shipman could produce 
on a stand-alone basis through fiscal year 2002 on the basis of capital 
available for distribution to Shipman stockholders in the form of dividends.  
Southard Financial also estimated the present value of the future stream of 
after-tax cash flow that Shipman could produce after giving effect to, among 
other things, certain cost savings expected from the merger on the basis of 
capital available for distribution to Shipman shareholders in the form of 
dividends.  The estimated terminal value was based upon a multiple of 
earnings of 15x.  Based upon an investor's required rate of return of 16%, 
the analysis indicated a value of Shipman in the range of $185 to $245 per 
share.  The implied valuation ranges are consistent with the terms of the 
offer from CNB.

     LIQUIDITY:  Like Shipman stock, CNB shares are not traded on an 
exchange. CNB indicated that there is a waiting list for the purchase of 
shares, but that the actual trading activity has been very thin.  Further, 
except in the case of officers, directors, and certain large Shipman 
stockholders, CNB shares received will be freely tradable with no 
restrictions.

     MERGER PREMIUM:  Based upon the Merger terms, Shipman stockholders who 
elect the cash option will receive a premium of approximately 25% over the 
most recent minority trading price of Shipman shares. Based upon the Merger 
terms and Southard's estimated market value of CNB Common Stock, Shipman 
stockholders who elect the stock option will receive a premium of 

                                       20

<PAGE>

approximately 85% over the most recent minority trading price of Shipman 
shares.  The merger premium for Shipman is consistent with the normal range 
for similar transactions.

     ANALYSIS OF ALTERNATIVES:  In evaluating the fairness of the proposed 
Merger to the Shipman stockholders, Southard Financial reviewed with Shipman 
management the process undertaken for the sale of the company and reviewed 
other offers received.  Further, negotiations took place with CNB over about 
a three and one-half month period before the definitive Merger Agreement was 
reached.

     Southard Financial's conclusion was that the terms of the proposed 
Merger pursuant to the Merger Agreement are fair, from a financial viewpoint, 
to the Shipman Stockholders.

IMPACT OF AN EXCHANGE OF SHIPMAN STOCK FOR CNB STOCK

     In conjunction with the Fairness Opinion, Southard Financial also 
provided Shipman stockholders with the following analyses:
     
     DIVIDEND YIELD ANALYSIS:  In evaluating the impact of the proposed 
merger on the Shipman stockholders, Southard Financial reviewed the dividend 
paying histories of Shipman and CNB.  Based upon this review, the impact on 
the dividends received by Shipman stockholders who elect to receive CNB 
Common Stock will be decidedly positive.  This is predicated on the 
assumption that CNB will continue per share dividends at or above current 
levels.

     EARNINGS YIELD ANALYSIS:  In evaluating the impact of the proposed 
merger on the Shipman stockholders, Southard Financial determined that, based 
upon an exchange ratio of 2:1, the Shipman stockholders would have seen a 
119.2% increase in earnings per share (defined as post merger combined 
earnings per share times the assumed exchange ratio), had the Merger been 
consummated prior to January 1, 1997.

     BOOK VALUE ANALYSIS: In evaluating the impact of the proposed Merger on 
the Shipman stockholders, Southard Financial determined that the Shipman 
stockholders would have experienced a 56.8% increase in the book value of 
their investment, based upon the book values of Shipman and CNB at March 31, 
1998.

     FUNDAMENTAL ANALYSIS: Southard Financial reviewed the financial 
characteristics of Shipman and CNB with respect to profitability, capital 
ratios, liquidity, asset quality and other factors.  Southard Financial 
compared Shipman and CNB to a universe of publicly traded banks and bank 
holding companies and to peer groups prepared by the Federal Financial 
Institutions Examination Council.  Southard Financial found that the 
post-merger combined entity would have capital ratios and profitability 
ratios near those of the public peer group.
     
     Southard Financial is a financial valuation consulting firm, 
specializing in the valuation of closely-held companies and financial 
institutions.  Since its founding in 1987, Southard Financial has provided 
approximately 2,000 valuation opinions for clients in 43 states.  Further, 
Southard Financial provides valuation services for approximately 120 
financial institutions annually.  For rendering its opinion, Southard 
Financial received a fee of $17,500, plus reasonable out-of-pocket expenses.  
Southard Financial has never been engaged previously by CNB, but has provided 
professional valuation services to Shipman since 1995. Neither Southard 
Financial nor its principals own an interest in the securities of Shipman or 
CNB.
     
EFFECTIVE TIME; CLOSING DATE

     In order to consummate the Merger, CNB and Shipman must file Articles of 
Merger with the Secretary of State of the State of Illinois.  Such filing 
will occur only after the receipt of all regulatory approvals and the 
approval of the Merger Agreement by the Shipman Stockholders and the 
satisfaction or waiver of all other conditions to the Merger (SEE 
"--CONDITIONS TO THE MERGER").  The Closing of the Merger will take place on 
a date mutually agreed upon by CNB and Shipman.  In the absence of such 
agreement, the Closing shall be held on the fifth business day after the last 
to occur of:  (i) the receipt of all approvals and consents of government 
regulatory authorities as legally required to consummate the Merger and the 
expiration of all statutory waiting periods; and (ii) the approval of the 
Merger Agreement by the Shipman Stockholders.  The parties will execute, 
acknowledge and file with the Secretary of State of the State of Illinois, in 
accordance with governing corporate 

                                       21

<PAGE>

law, the Articles of Merger on the Closing Date upon the satisfaction of all 
conditions precedent to the consummation of the transactions contemplated by 
the Merger Agreement.  The Effective Time of the Merger will be as of the 
close of business as of the day on which the Certificate of Merger is issued 
by the Secretary of State of the State of Illinois.  

EXCHANGE OF CERTIFICATES BY SHIPMAN STOCKHOLDERS

     After the mailing to Shipman Stockholders of this Proxy 
Statement-Prospectus, CNB will mail or cause to be mailed to each Shipman 
Stockholder transmittal materials for use in surrendering the stock 
certificates representing the shares of Shipman Common Stock held by him or 
her (the "Shipman Certificates"), including a Form of Election that will 
allow holders of Shipman Common Stock to make a Cash Election, Stock Election 
or Partial Cash Election and Partial Stock Election, and provide instructions 
for the transmittal of the Certificates.  CNB and Shipman have appointed the 
Carlinville Bank as exchange agent (the "Exchange Agent") for the parties to 
effect the surrender of the Certificates in exchange for either cash, CNB 
Common Stock or a combination thereof.

     SHIPMAN STOCKHOLDERS SHOULD NOT SEND IN THEIR SHIPMAN CERTIFICATES UNTIL 
THEY RECEIVE THE TRANSMITTAL MATERIALS FROM THE EXCHANGE AGENT.

     Following the consummation of the Merger, upon the delivery by a Shipman 
Stockholder to the Exchange Agent of all necessary transmittal materials and 
the Shipman Certificates and satisfactory proof of ownership of shares not 
represented by certificates, there will be mailed to such Stockholder a stock 
certificate or certificates representing shares of CNB Common Stock (the "CNB 
Stock Certificates") and/or a check for the amount representing any cash to 
be received by such Shipman Stockholder pursuant to an election and/or cash 
for any fractional shares of CNB Common Stock.  CNB Certificates may be 
issued in a name other than the name in which the surrendered Shipman 
Certificate is registered only if the Shipman Certificate is presented to the 
Exchange Agent, accompanied by all documents required to evidence and effect 
a transfer to the new name and by evidence that any applicable stock transfer 
taxes have been paid.

     No dividends or other distributions declared after the Effective Time 
with respect to CNB Common Stock payable to the holders of record thereof 
after the Effective Time will be paid to the holder of any unsurrendered 
Shipman Certificate (with respect to CNB Common Stock represented thereby) 
until the holder of record shall deliver such Shipman Certificate, along with 
the transmittal materials, to the Exchange Agent.  Subject to the effect, if 
any, of applicable law, after the subsequent delivery and exchange of a 
Shipman Certificate, the holder thereof will be entitled to receive any such 
dividends or distributions, without interest thereon, which theretofore 
became payable with respect to CNB Common Stock represented by such Shipman 
Certificate.  All dividends or other distributions declared on or after the 
Effective Time with respect to CNB Common Stock and payable to the holders of 
record thereof on or after the Effective Time which are payable to the holder 
of a Shipman Certificate not theretofore delivered and exchanged for CNB 
Common Stock shall be paid or delivered by CNB to the Exchange Agent, in 
trust, for the benefit of such holders. 

     All such dividends and distributions held by the Exchange Agent for 
payment or delivery to the holders of undelivered Shipman Certificates 
unclaimed at the end of one year from the Effective Time shall be repaid or 
redelivered by the Exchange Agent to CNB, after which time any holder of 
Shipman Certificates who has not theretofore delivered such Shipman 
Certificates to the Exchange Agent shall, subject to applicable law, be 
treated as a general creditor with respect to such amounts and shall look 
only to CNB for payment or delivery of such dividends or distributions, as 
the case may be.  Any shares of CNB Common Stock delivered or made available 
to the Exchange Agent and not exchanged for Shipman Certificates within one 
year after the Effective Time shall be returned by the Exchange Agent to CNB 
which will thereafter act as Exchange Agent subject to the rights of holders 
of unsurrendered Shipman Certificates.

DISSENTERS' APPRAISAL RIGHTS

     Any Shipman Stockholders who do not vote in favor of the Merger 
Agreement and who give written notice prior to the vote by the Shipman 
Stockholders on the Merger Agreement may demand dissenters' appraisal rights 
pursuant to Sections 11.65 and 11.70 of the IBCA ("Dissenting Stockholders"). 
 Copies of these sections are attached as Appendix C hereto.  Dissenting 
Stockholders may elect to receive payment in cash in an amount 

                                       22

<PAGE>

equal to the estimated "fair value" of their shares of Shipman Common Stock, 
which will be the value of the shares (as determined in a manner set forth 
below) immediately before the consummation of the Merger excluding any 
appreciation or depreciation in anticipation of the Merger, unless such 
exclusion would be inequitable.  The following is a summary of the procedural 
steps which must be taken to ensure that a Dissenting Stockholder's appraisal 
rights are recognized. 

     IT IS A CONDITION TO CNB'S OBLIGATION TO CONSUMMATE THE MERGER, THAT 
DISSENTERS' APPRAISAL RIGHTS NOT BE PERFECTED WITH RESPECT TO MORE THAN 10% 
OF THE OUTSTANDING SHIPMAN COMMON STOCK.  SEE "--"CONDITIONS TO THE MERGER."

     A SHIPMAN STOCKHOLDER DESIRING TO PERFECT HIS OR HER DISSENTING RIGHTS 
AND PAYMENT FOR HIS OR HER SHARES PURSUANT TO SECTIONS 11.65 AND 11.70 OF THE 
IBCA MUST MAIL OR DELIVER TO SHIPMAN (ATTENTION:  RONALD P. BOLLINGER, 
SECRETARY, SHIPMAN BANCORP, INC., 111 KEATING STREET, SHIPMAN, ILLINOIS 
62685), A WRITTEN DEMAND FOR PAYMENT OF HIS OR HER SHARES BEFORE THE VOTE ON 
THE MERGER AGREEMENT IS TAKEN, AND SUCH STOCKHOLDER MUST NOT VOTE IN FAVOR OF 
THE MERGER AGREEMENT. THE DELIVERY OF A PROXY WITH INSTRUCTIONS TO VOTE THE 
SHARES REPRESENTED THEREBY AGAINST APPROVAL OF THE MERGER AGREEMENT WILL NOT, 
BY ITSELF, SATISFY THE REQUIREMENT OF A WRITTEN DEMAND. 

     Only a holder of record is entitled to request dissenters' appraisal 
rights and payment for the shares registered in his or her name.  A record 
owner of shares may assert dissenters' appraisal rights as to fewer than all 
of the shares recorded in such person's name only if such person dissents 
with respect to all shares beneficially owned by any one person and notifies 
Shipman in writing of the name and address of each person on whose behalf the 
record owner asserts dissenters' appraisal rights.  The rights of a partial 
dissenter are determined as if the shares as to which dissent is made and the 
other shares held by such holder of record are recorded in the names of 
different Shipman Stockholders.  A beneficial owner of shares who is not the 
record owner may assert dissenters' appraisal rights as to shares held on 
such person's behalf only if the beneficial owner submits to Shipman the 
record owner's written consent to the dissent before or at the same time the 
beneficial owner asserts dissenters' appraisal rights.  

     A demand must reasonably inform Shipman of the identity of the holder of 
record of the Shipman Common Stock covered by the demand and that such holder 
of record demands payment for such shares. The demand should be executed by 
or for the Shipman Stockholder of record, fully and correctly, as such 
Stockholder's name appears on the Shipman Certificate(s).

     A Shipman Stockholder who makes written demand for payment retains all 
other rights of a stockholder until those rights are cancelled or modified at 
the Effective Time by the consummation of the Merger.  Within ten days after 
the Effective Time, CNB shall send each dissenting Shipman Stockholder who 
has delivered a written demand for payment, a statement setting forth the 
opinion of CNB as to the estimated fair value of the shares of Shipman Common 
Stock, Shipman's 1997 financial statements and Shipman's latest available 
interim financial statements and a commitment to pay for the shares of the 
Dissenting Stockholder the estimated fair value thereof upon transmittal to 
CNB of the Shipman Certificate or Certificates. 

     Upon consummation of the Merger, and given demand for payment by a 
Dissenting Stockholder, CNB shall, upon receipt of the Shipman Certificate, 
pay the amount CNB estimates to be the fair value of the shares, plus accrued 
interest, if any.  An explanation of how the interest was calculated will be 
provided by CNB to the Dissenting Stockholder at the time that CNB pays the 
amount it estimates to be the fair value of the shares.

     If the Dissenting Stockholder does not agree with the opinion of CNB as 
to the estimated fair value of the shares, or the amount of interest due, he 
or she shall, within thirty days from the delivery of CNB's statement of 
value, notify CNB in writing of such Dissenting Stockholder's determination 
of the estimated fair value and interest due relating to the shares, and 
demand payment of the difference.

     If within sixty days after delivery of such written notification by a 
Dissenting Stockholder, CNB and the Dissenting Stockholder are unable to 
agree as to the value of the shares, CNB shall either pay the difference in 
value demanded by the Dissenting Stockholder, with interest, or file a 
petition in the Circuit Court of Macoupin County, Illinois requesting a 
determination of the fair value of the shares and the interest due.  All 
Dissenting 

                                       23

<PAGE>

Stockholders who have perfected their dissenters' appraisal rights and who 
have not settled with CNB will be made parties to this proceeding.  The cost 
of the proceedings may be assessed against one or more parties to the 
proceedings as the court may consider equitable.  Failure of CNB to commence 
an action shall not limit or affect the right of the Dissenting Stockholder 
to otherwise commence an action as permitted by law.

     The foregoing is only a summary of the provisions of the IBCA and is 
qualified in its entirety by reference to the text of Sections 11.65 and 
11.70 of the IBCA which are set forth in Appendix C hereto and incorporated 
by reference herein.  ANY STOCKHOLDER OF SHIPMAN WHO DESIRES TO EXERCISE HIS 
OR HER DISSENTERS' APPRAISAL RIGHTS SHOULD CAREFULLY REVIEW APPENDIX C AND 
CONSULT A LEGAL ADVISOR BEFORE ELECTING OR ATTEMPTING TO EXERCISE SUCH RIGHTS.

     The holders of CNB Common Stock do not have dissenters' appraisal rights 
in connection with the Merger because Shipman is merging with Acquisition 
Corp. CNB is not a participant in the Merger and, therefore, under the 
Delaware General Corporation Law (the "DGCL"), no dissenters' appraisal 
rights are available.  

REGULATORY APPROVALS

     The Merger is subject to the prior approval of the Federal Reserve and 
the Illinois Commissioner.  CNB filed applications for approval of the Merger 
with the Federal Reserve and the Illinois Commissioner on June 10, 1998.  CNB 
anticipates obtaining the approval of the Federal Reserve and the Illinois 
Commissioner during the third quarter of 1998.  There can be no assurance as 
to the timing of such approvals or that the Federal Reserve and the Illinois 
Commissioner will approve the Merger.

     The Merger is subject to prior approval by the Federal Reserve under 
Section 3 of the BHCA.  Section 3 of the BHCA requires the Federal Reserve, 
when considering a transaction such as the Merger, to take into consideration 
the financial and managerial resources (including the competence, experience 
and integrity of the officers, directors and principal stockholders), and the 
future prospects of the existing and proposed institutions and the 
convenience to and the needs of the communities to be served.  In considering 
financial resources and future prospects, the Federal Reserve will, among 
other things, evaluate the adequacy of the capital levels of the parties to a 
proposed transaction and of the resulting institutions.

     The BHCA prohibits the Federal Reserve from approving a merger: (i) if 
it would result in a monopoly or be in furtherance of any combination or 
conspiracy to monopolize or to attempt to monopolize the business of banking 
in any part of the United States, or (ii) if its effect in any section of the 
country would be to substantially lessen competition or to tend to create a 
monopoly, or if it would in any other respect result in a restraint of trade, 
unless the Federal Reserve finds that the anti-competitive effects of the 
merger are clearly outweighed by the probable effect of the transaction in 
meeting the convenience and needs of the communities to be served.  In 
addition, under the Community Reinvestment Act of 1977, as amended (the 
"CRA"), the Federal Reserve must take into account the record of performance 
of the existing institutions in meeting the credit needs of the entire 
community, including low- and moderate-income neighborhoods, served by such 
institutions.  

     The Federal Reserve will furnish notice and a copy of the application 
for approval of the Merger to the Federal Deposit Insurance Corporation (the 
"FDIC") and the Office of the Comptroller of the Currency (the "OCC").  These 
agencies have thirty days to submit their views and recommendations to the 
Federal Reserve.  The Federal Reserve is required to hold a public hearing in 
the event it receives a written recommendation of disapproval of the 
application from the FDIC or the OCC within such thirty day period.  
Furthermore, applicable federal law provides for the publication of notice 
and public comment on applications filed with the Federal Reserve and 
authorizes such agency to permit interested parties to intervene in the 
proceedings.  If an interested party is permitted to intervene, such 
intervention could delay the regulatory approvals required for consummation 
of the Merger.

     In addition, under federal law, a period of 30 days must expire 
following approval by the Federal Reserve within which period the United 
States Department of Justice (the "Department of Justice") may file 
objections to the Merger under the federal antitrust laws.  The Department of 
Justice could take such action under

                                       24

<PAGE>

the antitrust laws as it deems necessary or desirable in the public interest, 
including seeking to enjoin the Merger, unless divestiture of an acceptable 
number of branches to a competitively suitable purchaser could be made.  
While CNB believes that the likelihood of such action by the Department of 
Justice is remote in this case, there can be no assurance that the Department 
of Justice will not initiate such a proceeding.

     The Merger may not be consummated until the 30th day (or, with the 
consent of the relevant agencies, the 15th day) following the date of the 
requisite Federal Reserve approval, during which period the Department of 
Justice may comment adversely on the Merger (which has the effect of 
extending the waiting period to the 30th day following approval) or challenge 
the Merger on antitrust grounds.  The commencement of an antitrust action 
would delay the effectiveness of such an approval unless a court specifically 
orders otherwise.

     It is a condition to the consummation of the Merger that the Federal 
Reserve and Illinois Commissioner approvals not contain any non-standard 
conditions or restrictions.  If CNB reasonably determines that any such 
non-standard conditions or restrictions would be unduly burdensome to CNB or 
its subsidiaries, CNB will not be obligated to consummate the Merger.  There 
can be no assurance that the Federal Reserve approval or the Illinois 
Commissioner approval will not contain conditions or restrictions which cause 
such approval to fail to satisfy such conditions to the consummation of the 
Merger.

     THE MERGER WILL NOT PROCEED IN THE ABSENCE OF THE REQUISITE REGULATORY 
APPROVALS.  THERE CAN BE NO ASSURANCE THAT SUCH REGULATORY APPROVALS WILL BE 
OBTAINED, AND IF THE MERGER IS APPROVED, THERE CAN BE NO ASSURANCE AS TO THE 
DATE OF ANY SUCH APPROVAL.  THERE CAN ALSO BE NO ASSURANCE THAT SUCH 
APPROVALS WILL NOT CONTAIN A CONDITION OR RESTRICTION WHICH CAUSES SUCH 
APPROVALS TO FAIL TO SATISFY THE CONDITIONS SET FORTH IN THE MERGER 
AGREEMENT.  THERE CAN LIKEWISE BE NO ASSURANCE THAT THE DEPARTMENT OF JUSTICE 
OR A STATE ATTORNEY GENERAL WILL NOT CHALLENGE THE MERGER, OR IF SUCH A 
CHALLENGE IS MADE, AS TO THE OUTCOME THEREOF.  

BUSINESS PENDING THE MERGER AND OTHER COVENANTS

     CNB and Shipman have agreed to conduct their respective businesses in 
accordance with certain guidelines contained in the Merger Agreement.  Until 
the consummation of the Merger or the termination of the Merger Agreement, 
Shipman and CNB have each agreed (except as specifically noted below), among 
other things, that each of them (and each of their respective subsidiaries) 
will:

     (a)  conduct its businesses only in the ordinary course;

     (b)  use its best efforts to preserve intact its current business 
organizations, keep available the services of its current officers, employees 
and agents and maintain the relations and goodwill with suppliers, customers, 
landlords, creditors, employees, agents and others having business 
relationships with it, and each of CNB and Shipman will inform the other as 
soon as it becomes aware of the potential loss or diminution in the 
relationship with any consequential customer;

     (c)  confer with each other concerning operational matters of a material 
nature; 

     (d)  with respect to Shipman only, enter into loan and other financing 
transactions only in accordance with sound credit and other internal policies 
and only on terms and conditions consistent with arm's-length transactions, 
and subject to certain dollar limits, without the prior written approval of 
CNB or the failure by CNB to respond to such request for approval within one 
day after such a request for approval is made by Shipman;

     (e)  consistent with past practice, maintain a reserve for possible loan 
losses which is adequate in all material respects under the requirements of 
generally accepted accounting principles to provide for possible losses, net 
of recoveries relating to loans previously charged off, on loans outstanding 
(including accrued interest receivable); 

                                       25

<PAGE>

     (f)  maintain all assets necessary for the conduct of business in good 
operating condition and repair, reasonable wear and tear and damage by fire 
or unavoidable casualty excepted, and maintain policies of insurance upon 
such assets and with respect to the conduct of such business in amounts and 
kinds comparable to that in effect on the date of the Merger Agreement and 
pay all premiums on such policies when due;

     (g)  file in a timely manner all required filings with all regulatory 
authorities and cause such filings to be true and correct in all material 
respects; and

     (h)  maintain books, accounts and records in the usual, regular and 
ordinary manner, on a basis consistent with prior years and comply in all 
material respects with all legal requirements applicable to it.

     The Merger Agreement also provides that prior to the Effective Time, 
without CNB's prior written consent (and except as provided in the Merger 
Agreement), neither Shipman nor Citizens Bank may, among other things:  (a) 
change its authorized or issued capital stock; (b) grant any stock option or 
right to purchase shares of capital stock; (c) issue or redeem any of its 
capital stock or declare or pay any dividend or make any other distribution 
to its stockholders (except for dividends paid solely by Citizens Bank to 
Shipman); (d) amend its charter or bylaws; (e) pay or increase any bonuses, 
salaries or other compensation to any stockholder or director, officer or 
employee (except in the ordinary course of business) or enter into any 
employment, severance or similar contract with any director, officer or 
employee; (f) adopt or amend in any material manner (except in order to 
comply with any legal requirements), or terminate, or increase the payments 
to or benefits under, any employee benefit plan; (g) terminate any material 
contract; (h) materially change any existing material lease of real or 
personal property; (i) sell, lease or otherwise dispose of any material asset 
or property or mortgage, pledge or impose any lien or otherwise encumber any 
material asset or property; (j) incur any obligation or liability (fixed or 
contingent) other than in the ordinary course of business; or (k) enter into 
any transaction providing for the borrowing or loaning of monies, other than 
in the ordinary course of business.  In addition, Shipman has agreed that it 
will not merge or consolidate with or into any other person, or acquire any 
stock, equity interest or business of any other person.

     CNB has agreed in the Merger Agreement that without Shipman's prior 
written consent (and except as provided in the Merger Agreement), neither CNB 
nor any of its subsidiaries may, among other things:  (a) change its 
authorized or issued capital stock; (b) grant any stock option or right to 
purchase shares of capital stock; (c) issue or redeem any of its capital 
stock or declare or pay any dividend or make any other distribution to its 
stockholders (other than in accordance with past practice) (d) amend its 
charter or bylaws; or (e) pay or increase any bonuses, salaries or other 
compensation to any stockholder or director, officer or employee (except in 
the ordinary course of business) or enter into any employment, severance or 
similar contract with any director, officer or employee.

     Shipman has also agreed that prior to the Effective Time, neither 
Shipman nor Citizens Bank nor any of its respective representatives will:  
(i) solicit, initiate, participate in discussions of, or encourage or take 
any other action to facilitate any inquiry or the making of any proposal 
relating to an Acquisition Transaction (as defined below) or a potential 
Acquisition Transaction with respect to itself or Citizens Bank; or (ii) 
solicit, initiate, participate in discussions of, or encourage or take any 
other action to facilitate any inquiry or proposal or enter into any 
agreement, arrangement, or understanding, regarding any proposal or 
transaction providing for or requiring it to abandon, terminate or fail to 
consummate the Merger Agreement, or compensating Shipman or Citizens Bank 
under any of the instances described. Shipman is to instruct and otherwise 
use its best efforts to cause its representatives (including any 
representative of Citizens Bank) to comply with such prohibitions.  Shipman 
is also obligated to cease and cause to be terminated any activities, 
discussions, or negotiations with any persons conducted before March 27, 
1998, with respect to such activities.  

     Notwithstanding the foregoing, Shipman may provide information at the 
request of, or enter into discussions or negotiations with, a person with 
respect to an Acquisition Transaction if the Shipman Board determines, in 
good faith, that the exercise of its fiduciary duties to the Shipman 
Stockholders under applicable law requires it to take such action.  Shipman 
may not, in any event, provide to such person any information which it has 
not provided to CNB. Shipman must promptly notify CNB orally and in writing 
in the event it receives any such inquiry or proposal and shall provide 
reasonable detail of all relevant facts relating to such inquiries. 

                                       26

<PAGE>

     "Acquisition Transaction" as defined in the Merger Agreement shall, with 
respect to Shipman, mean any of the following: (i) a merger or consolidation, 
or any similar transaction of any company with either Shipman or Citizens 
Bank; (ii) a purchase, lease or other acquisition of all or substantially all 
the assets of either Shipman or Citizens Bank; (iii) a purchase or other 
acquisition of beneficial ownership by any person or group which would cause 
such person or group to become the beneficial owner of securities 
representing 20% or more of the voting power of either Shipman or Citizens 
Bank; (iv) a tender or exchange offer to acquire securities representing 10% 
or more of the voting power of Shipman; (v) a public proxy or consent 
solicitation made to Shipman Stockholders, seeking proxies in opposition to 
any proposal relating to any of the transactions contemplated by the Merger 
Agreement; (vi) the filing of an application or notice with the Federal 
Reserve or any other federal or state regulatory authority seeking approval 
to engage in one or more of the transactions referenced in (i) through (iv) 
above; or (vii) the making of a bona fide proposal to Shipman or its 
stockholders by public announcement or written communication, that is or 
becomes the subject of public disclosure, to engage in one or more of the 
transactions referenced in clauses (i) through (v) above.

     Shipman has also agreed to recommend to its stockholders approval of the 
Merger Agreement and to solicit proxies in favor of the Merger Agreement from 
its stockholders.

     In the Merger Agreement, Shipman and CNB have agreed to use their best 
efforts in good faith to satisfy the various covenants and conditions to 
Closing applicable to CNB or Shipman, as the case may be, contained in the 
Merger Agreement and to consummate the transactions contemplated by the 
Merger Agreement as promptly as possible.  Furthermore, the Merger Agreement 
provides that neither CNB nor Shipman will intentionally take or 
intentionally permit to be taken any action that would be a breach of the 
terms or provisions of the Merger Agreement or would cause its 
representations and warranties to be or become untrue.  Between March 27, 
1998, and the Closing Date, Shipman will, and will cause Citizens Bank to, 
cooperate with CNB with respect to all filings that are contemplated by the 
Merger Agreement  or required to be made in connection with the transactions 
contemplated by the Merger Agreement.

     Between March 27, 1998, and the Closing Date, each of CNB or Shipman 
will promptly notify the other in writing if it acquires knowledge of any 
fact or condition that causes or constitutes a breach of any of its 
representations and warranties as of the date of the Merger Agreement, or if 
it acquires knowledge of the occurrence after the date of the Merger 
Agreement of any fact or condition that would (except as expressly 
contemplated by the Merger Agreement) cause or constitute a breach of any of 
its representations or warranties had such representation or warranty been 
made as of the time of occurrence or discovery of such fact or condition.  
During the same period, CNB and Shipman will promptly notify the other of the 
occurrence of any breach of any covenant in the Merger Agreement or of the 
occurrence of any event that may make the satisfaction of the conditions to 
Closing impossible or unlikely.

     The Merger Agreement prohibits Shipman and CNB and their subsidiaries 
from taking any voluntary action that would disqualify the Merger as a 
"reorganization" that would be tax free or deferred to Shipman Stockholders 
receiving CNB common stock.  SEE "-- FEDERAL INCOME TAX CONSEQUENCES OF THE 
MERGER." 

ENVIRONMENTAL INVESTIGATION

     The Merger Agreement provides that if requested by CNB, Shipman must 
engage an environmental consultant acceptable to CNB to conduct a preliminary 
("Phase I") environmental assessment of each of the parcels of real estate 
used in the operation of the businesses of Shipman and Citizens Bank and any 
other real estate owned by Shipman or a subsidiary of Shipman (other than 
single family residences).  The fees and expenses of the consultant with 
respect to the Phase I assessments will be paid by Shipman.  If the estimated 
cost to remediate any environmental conditions are found, suspected, or would 
tend to be indicated by the report of the consultant exceeds $20,000, and if 
CNB and Shipman have been unable to agree upon a mutually acceptable 
modification of the Merger Agreement, CNB will have the right to terminate 
the Merger Agreement. 

REPRESENTATIONS AND WARRANTIES

     CNB and Shipman made a series of representations and warranties to each

representations and warranties must be accurate in all material respects as 
of the Closing Date. SEE "--CONDITIONS TO THE MERGER."  As of the date of 
this Proxy Statement-Prospectus, neither CNB nor Shipman has any knowledge 
that this condition will not be satisfied as of the Closing Date.

following conditions, among others:  (i) the representations and warranties 
made by a party in the Merger Agreement (considered collectively) must have 
been accurate in all material respects as of the date of the Merger 
Agreement, and must be accurate in all material respects as of the Closing

been commenced or threatened against a party, or against any affiliate of a 
party, any proceeding involving any challenge to, or seeking damages or other 
relief in connection with, any of the transactions contemplated by the Merger 
Agreement, or that may have the effect of preventing, delaying, making 
illegal or otherwise interfering with any of the transactions contemplated by 
the Merger Agreement, in either case that would reasonably be expected to 
have a material adverse effect on such party; (v) there shall be and have 
been no event or occurrence that had or would reasonably be expected to have 
a material adverse effect on CNB or Shipman, as the case may be; (vi) any

Merger Agreement or otherwise reasonably necessary in the opinion of the 
other party to consummate the transactions contemplated by the Merger 
Agreement shall have been obtained and shall be reasonably satisfactory to 
the other party, and all applicable waiting periods shall have expired; (vii) 
neither the consummation nor the performance of any of the transactions 
contemplated by the Merger Agreement will, directly or indirectly (with or 
without notice or lapse of time), contravene, or conflict with or result in a 
violation of, or cause a party or any affiliate of a party to suffer any 
adverse consequence under any applicable legal requirement or order, or any 
legal requirement or order that has been published, introduced, or otherwise 
proposed by or before any regulatory authority, where any of the foregoing 
would reasonably be expected to have a material adverse effect on CNB or 
Shipman, as the case may be; (viii) the Registration Statement filed by CNB 
with the Commission with respect to the CNB Common Stock to be issued 
pursuant to the Merger Agreement shall have become effective and no stop 
order proceedings with respect thereto shall be pending or threatened; (ix) 
in the case of CNB's obligations, the Merger Agreement and the transactions 
contemplated thereby shall have been duly and validly authorized as required 
by all applicable legal requirements by the Shipman Stockholders; (x) in the 
case of CNB's obligations, the total number of shares of Shipman Common Stock 
for which Shipman Stockholders have perfected  dissenters' appraisal rights 
shall be no greater than 10% of the number of shares of Shipman Common Stock 
issued and outstanding immediately prior to the Effective Time; (xi) in the 
case of Shipman's obligations, the opinion received by Shipman from Southard 
shall not have been withdrawn or materially modified prior to the Closing 
(SEE "--OPINION OF SHIPMAN FINANCIAL ADVISOR"); (xii) in the case of 
Shipman's obligations, Shipman shall have received a tax opinion (SEE 
"--FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER"); and (xiii) in the case of 
CNB's obligations, the cost of any environmental remediation with respect to 
Shipman's real property shall be less than $20,000.

     As of the date of this Proxy Statement-Prospectus, neither CNB nor 
Shipman has any knowledge that any of the aforementioned Closing conditions 
will not be satisfied by the Closing Date. 

WAIVER AND AMENDMENT; TERMINATION

     Prior to the Effective Time, the CNB and Shipman Boards may extend the 
time for performance of any obligation under the Merger Agreement, waive any 
inaccuracies in the representations and warranties contained in the Merger 
Agreement and waive compliance with any agreements or conditions contained in 
the Merger Agreement.  Subject to applicable law, the Merger Agreement may be 
amended by action of the CNB and Shipman Boards at any time before or after 
approval of the Merger Agreement by the Shipman Stockholders. 

                                       28
<PAGE>

     The Merger Agreement may be terminated at any time prior to the 
Effective Time by the mutual agreement of the parties.  In addition, the 
Merger Agreement may be terminated at any time prior to the Effective Time:  
(i) by a non-breaching party, if a party commits a material breach of the 
Merger Agreement; (ii) by the party for whose benefit a Closing condition 
exists, if the Closing condition has not been satisfied as of the Closing 
Date, or if satisfaction of such condition becomes impossible (other than due 
to the failure of a party for whose benefit the Closing condition exists to 
comply with its obligations under the Merger Agreement) and such condition is 
not waived by the Closing Date by the party who for whose benefit such 
condition exists; or (iii) by either party, if the Closing has not occurred 
(other than through the failure of the party seeking to terminate the Merger 
Agreement to comply fully with its obligations under the Merger Agreement) by 
January 27, 1999.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     GENERAL.  Certain members of Shipman's management and the Shipman Board 
may be deemed to have certain interests in the Merger in addition to their 
interests as Shipman Stockholders generally.  These material interests 
include, among others, provisions in the Merger Agreement relating to 
indemnification, maintenance of director and officer liability insurance 
coverage and the appointment of one member of the Shipman Board, James H. 
Frank, to the CNB Board following the consummation of the Merger.  CNB has 
also agreed that not less than two nor more than four of the current 
directors of Citizens Bank will be retained by CNB after the Effective Time 
as directors of Citizens Bank.  The Shipman Board was aware of all of the 
interests discussed below and considered them, among other matters, in 
approving the Merger Agreement and the transactions contemplated thereby. 

     DIRECTORS' AND OFFICERS' INDEMNIFICATION RIGHTS.  The Merger Agreement 
provides that, upon consummation of the Merger, CNB will maintain, except as 
may be limited by applicable law, all rights of indemnification currently 
provided by Shipman and Citizens Bank in favor of their current and former 
employees, directors, officers and agents on terms no less favorable than 
those provided in the Articles of Incorporation or Bylaws of Shipman or 
otherwise in effect on March 27, 1998.  SEE "COMPARISON OF THE RIGHTS OF CNB 
STOCKHOLDERS AND SHIPMAN STOCKHOLDERS--LIABILITY OF DIRECTORS; 
INDEMNIFICATION."  

     DIRECTORSHIPS.  The Merger Agreement provides that James H. Frank, a 
current director of Shipman, will be appointed to serve as a director of CNB 
as soon as practicable after the Effective Time.  His term will expire at the 
Annual Meeting of CNB Stockholders to be held in the year 1999.  CNB has also 
agreed that not less than two nor more than four of the current directors of 
Citizens Bank will be retained by CNB after the Effective Time as directors 
of Citizens Bank.  The terms of these directors of Citizens Bank will expire 
in 1999.  SEE "CNB DIRECTOR ELECTION--ELECTION OF DIRECTORS."

EFFECT ON EMPLOYEE BENEFITS

     The Merger Agreement provides, among other things, that upon the written 
request of CNB, Shipman will take any necessary action to terminate any 
employee benefit plan of Shipman or Citizens Bank on or before the Closing on 
terms reasonably acceptable to CNB, PROVIDED, HOWEVER, that neither Shipman 
nor the Citizens Bank will be obligated to take any such requested action 
that is irrevocable until immediately prior to the Closing and at such time 
as Shipman shall have received reasonable assurances that all conditions 
precedent to Shipman's obligations under the Merger Agreement (except for the 
completion of actions to be taken at the Closing) have been satisfied. 

     After the Closing, CNB expects to review all of its employee benefits 
plans and decide upon a coordinated package of benefits for the employees of 
each of its subsidiaries, including Shipman and Citizens Bank. 

FEDERAL INCOME TAX CONSEQUENCES  OF THE MERGER

     The discussion set forth below is a general description of the material 
Federal income tax consequences of the Merger to certain Shipman Stockholders 
and does not purport to be a complete analysis or listing of all potential 
tax considerations or consequences relevant to a decision to vote for the 
approval of the Merger.  The discussion does not address all aspects of 
Federal income taxation that may be applicable to Shipman Stockholders 

                                       29
<PAGE>

subject to special Federal income tax treatment, including, without 
limitation, foreign persons, insurance companies, tax exempt entities, 
retirement plans, dealers in securities and persons who acquired their 
Shipman Common Stock pursuant to the exercise of employee stock options or 
otherwise as compensation.  The discussion addresses neither the effect of 
any applicable state, local or foreign tax laws, nor the affect of any 
Federal tax laws other than those pertaining to the Federal income tax.  IN 
VIEW OF THE INDIVIDUAL NATURE OF FEDERAL INCOME TAX CONSEQUENCES, EACH 
SHIPMAN STOCKHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISOR TO 
DETERMINE THE SPECIFIC CONSEQUENCES OF THE MERGER TO HIM OR HER. 

     This discussion is based upon the Code and the regulations and rulings 
promulgated in connection therewith that are now in effect or proposed 
thereunder, current administrative rulings and practices and judicial 
precedent, all of which are subject to change.  Any such change, which may or 
may not be retroactive, could alter the tax consequences to Shipman 
Stockholders discussed herein.  This discussion is also based upon certain 
assumptions regarding the factual circumstances that will exist at the 
Closing Date, and thereafter, including certain representations to be made by 
Shipman and CNB.  This discussion assumes that Shipman Stockholders hold 
their shares of Shipman Common Stock as a capital asset within the meeting of 
Section 1221 of the Code.  If any of these factual assumptions or 
representations are inaccurate, the tax consequences of the Merger could 
differ from those described herein.  

    The Merger is intended to constitute a "reorganization" for Federal 
income tax purposes under Section 368(a)(1)(A) of the Code, by reason of the 
application of Section 368(a)(2)(E) of the Code, with the following Federal 
income tax consequences:

     1)   Shipman Stockholders will recognize no gain or loss as a result of 
          the exchange of their Shipman Common Stock solely for shares of CNB 
          Common Stock.
     
     2)   The aggregate adjusted tax basis of the shares of CNB Common Stock 
          received by each Shipman stockholder in the Merger will be equal to 
          the aggregate adjusted tax basis of the shares of Shipman Common 
          Stock surrendered.
     
     3)   The holding period for the shares of CNB Common Stock received by 
          each Shipman stockholder in the Merger (including any fractional 
          share of CNB Common Stock deemed to be received) will include the 
          holding period of the shares of Shipman Common Stock exchanged 
          therefor.
     
     4)   A Shipman stockholder who receives cash will realize gain or loss 
          for Federal income tax purposes (determined separately as to each 
          block of Shipman Common Stock exchanged) in an amount equal to the 
          difference between (x) the amount of cash received by such 
          stockholder, and (y) such stockholder's tax basis for the shares of 
          Shipman Common Stock surrendered in exchange therefor, provided 
          that the cash payment does not have the effect of the distribution 
          of a dividend.  Any such gain or loss will be recognized for 
          Federal income tax purposes and will be treated as a capital gain 
          or loss.  In general, if a Shipman stockholder does not actually or 
          constructively own any CNB Common Stock after the Merger, the 
          distribution will not have the effect of the distribution of a 
          dividend.  However, if the cash payment does have the effect of the 
          distribution of a dividend, the amount of taxable income recognized 
          generally will equal the amount cash received; such income 
          generally will be taxable as a dividend; and no loss (or other 
          recovery of such stockholder's tax basis for the shares of Shipman 
          Common Stock surrendered in the exchange) generally will be 
          recognized by such stockholder.  The determination of whether a 
          cash payment has the effect of the distribution of the cash 
          dividend will be made pursuant to the provisions and limitations of 
          Section 302 of the Code, taking into account the constructive stock 
          ownership rules of Section 318 of the Code.

     Shipman's obligations to consummate the Merger are subject to the 
condition that it receive an opinion of its tax advisor to the effect that 
the receipt of the CNB Common Stock by Shipman Stockholders will not result 
in a gain or loss for tax purposes.  Such opinion will be subject to the 
conditions and assumptions stated therein and will also rely on various 
representations made by Shipman, certain Shipman Stockholders and CNB.  An 
opinion of a tax advisor, unlike a private letter ruling from the Internal 
Revenue Service (the "Service"), has no binding affect on the Service.  The 
Service could take a position contrary to the counsel's opinion and, if the 
matter were 

                                       30

<PAGE>

litigated, a court may reach a decision contrary to the opinion.  The Service 
is not expected to issue a ruling on the tax effects of the Merger, and no 
such ruling has been requested.  CNB and Shipman have not sought any opinion 
with respect to state or local tax consequences of the Merger to Shipman 
Stockholders.  

     THE FOREGOING IS A GENERAL DISCUSSION OF THE MATERIAL FEDERAL INCOME TAX 
CONSEQUENCES OF THE MERGER AND IS INCLUDED FOR GENERAL INFORMATION ONLY.  THE 
FOREGOING DISCUSSION DOES NOT TAKE INTO ACCOUNT THE PARTICULAR FACTS AND 
CIRCUMSTANCES OF EACH SHIPMAN STOCKHOLDER'S TAX STATUS AND ATTRIBUTES.  AS A 
RESULT, THE FEDERAL INCOME TAX CONSEQUENCES ADDRESSED IN THE FOREGOING 
DISCUSSION MAY NOT APPLY TO EACH SHIPMAN STOCKHOLDER.  IN VIEW OF THE 
INDIVIDUAL NATURE OF INCOME TAX CONSEQUENCES, EACH SHIPMAN STOCKHOLDER SHOULD 
CONSULT HIS/HER OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES OF 
THE MERGER TO SUCH STOCKHOLDER, INCLUDING THE APPLICATION AND EFFECT OF 
FEDERAL, STATE, LOCAL AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES 
IN FEDERAL AND OTHER TAX LAWS. 

     The consummation of the Merger is conditioned, among other things, upon 
the receipt by Shipman of an opinion from Cummings, dated as of the Effective 
Time, to the foregoing effect.  SEE "-- CONDITIONS TO THE MERGER."

RESALE OF CNB COMMON STOCK

     Shares of CNB Common Stock issued to Shipman Stockholders will be 
transferable without restriction upon disposition, except shares issued to 
any person who may be considered an "Affiliate" of Shipman, as defined by the 
rules and regulations of the Commission under the Securities Act.  Pursuant 
to the Merger Agreement, Shipman has delivered to CNB a written undertaking 
from each Affiliate of Shipman to the effect that he or she will not sell or 
dispose of CNB Common Stock acquired by him or her in connection with the 
Merger, other than in accordance with the Securities Act, except under: (i) a 
separate registration statement for distribution (which CNB has not agreed to 
provide), or (ii) Rule 145 promulgated thereunder by the Commission or (iii) 
pursuant to another exemption from registration.  In addition, Shipman 
Stockholders who become Affiliates of CNB will be subject to similar sale 
restrictions for as long as they remain Affiliates of CNB. 

               PRICE RANGE OF COMMON STOCK AND DIVIDENDS 

MARKET PRICES

     There is no established public trading market for either CNB Common 
Stock or Shipman Common Stock.  As of the Record Date, CNB Common Stock was 
held of record by approximately 155 persons and Shipman Common Stock was held 
of record by approximately 108 persons.  To the knowledge of CNB's 
management, five sales of CNB Common Stock occurred in 1997 involving an 
aggregate of 2,072 shares at prices ranging from $100 to $110 per share, and 
no sales of CNB Common Stock have occurred in 1998 through the Record Date.  
To the knowledge of Shipman's management, four sales of Shipman Common Stock 
occurred in 1997 involving an aggregate of 645 shares at prices of $135 per 
share, all of which were purchased by Shipman for the Shipman ESOP or to be 
held as treasury stock.  To the knowledge of Shipman's management, no sales 
of Shipman Common Stock occurred in 1998 through the date of this Proxy 
Statement-Prospectus.  SEE "COMPARATIVE PER SHARE DATA." 

DIVIDENDS

     The following table sets forth dividends declared per share of CNB 
Common Stock and Shipman Common Stock, respectively, for the periods 
indicated.  The ability of either CNB or Shipman to pay dividends to the 
respective holders of its Common Stock is subject to certain restrictions.

            NOTES TO PRO FORMA CONDENSED COMBINING FINANCIAL STATEMENTS
                DECEMBER 31, 1997, AND MARCH 31, 1998 AND 1997
                                  (UNAUDITED)

BACKGROUND:

CNB proposes to merge with Shipman in a transaction wherein CNB will exchange 
two shares of CNB Common Stock or $190 in cash, for each of the 32,035.8291 
outstanding shares of Shipman Common Stock, provided that at least 70% of 
Shipman's shareholders elect to receive CNB Common Stock.  The value used to 
record the issuance of CNB Common Stock is $95 per share, based on the $190 
cash price offered.

ASSUMPTIONS:
     
1.   The pro forma condensed combining balance sheet of CNB and its subsidiaries
and Shipman and its subsidiary as of March 31, 1998 has been prepared in
accordance with the following financial assumptions: 

     a.   The transaction referred to above occurs on March 31, 1998.

     b.   The transaction will be accounted for using the purchase method of 
          accounting, in which 100% of the outstanding common shares of 
          Shipman will be acquired by CNB for CNB Common Stock and cash.  
          Accordingly, the net assets of Shipman are adjusted to their fair 
          market value and no minority interest is considered.  The 
          components of the merger transaction are outlined as follows:

     The amount above for loans reflects the adjustments required to increase 
Shipman's carrying value of such assets to their estimated fair value.  The 
acquisition costs incurred include an estimate of merger costs.  Deferred 
taxes represent the estimated taxes to be incurred on these valuation 
adjustments.  In the opinion of CNB management, the net book value of all 
other net assets of Shipman does not differ materially with the appropriate 
fair value thereof.

                                 DESCRIPTION OF CNB
GENERAL

     CNB is a multi-bank holding company registered under the BHCA which owns 
all of the issued and outstanding capital stock of the Carlinville Bank and 
of Lincoln Trail.  Lincoln Trail owns all of the issued and outstanding stock 
of the Palmer Bank.  CNB also owns all of the issued and outstanding stock of 
Carlinville Tax Service, Inc., a subsidiary engaged in the preparation of tax 
returns and provision of bookkeeping services for various clients ("CTS").

     After serving the local community for 109 years from its single location 
in Carlinville, Illinois, on December 13, 1996, the Carlinville Bank 
purchased certain assets and assumed the liabilities of a branch facility in 
Hillsboro, Illinois, from an unaffiliated regional banking group (the 
"Hillsboro Branch"). Approximately five weeks later, CNB purchased all of the 
outstanding capital stock of Lincoln Trail and its wholly-owned subsidiary, 
Palmer Bank in Taylorville, Illinois.  These strategic acquisitions have 
transformed CNB from a single location, one bank holding company to a 
multi-bank holding company with five locations.

THE CNB BANKS

     The CNB Banks engage in general full service retail banking within 
central and southwestern Illinois.  Deposit products include certificates of 
deposit, individual retirement accounts and other time deposits, checking and 
other demand deposit accounts, NOW accounts, savings accounts and money 
market accounts.  Loans include commercial and industrial, agricultural, real 
estate mortgage, consumer, home equity, leasing and lines of credit.  Other 
products and services include VISA debit cards, automatic teller machines, 
safe deposit boxes and trust services.  CNB continues to explore new products 
and services to meet the needs and demands of its customer base and to remain 
competitive with other financial institutions operating in its market areas.

     Although each of the CNB Banks operates under the direction of its own 
board of directors, CNB has standard operating policies regarding 
asset/liability management, liquidity management, investment management, 
lending policies and deposit structure management.  CNB has historically 
centralized certain operations where economies of scale can be achieved.

MARKET AREA

     CNB's primary market area includes the four counties of Macoupin, 
Montgomery, Christian and Sangamon in central and southwestern Illinois.  The 
Carlinville Bank has offices in Carlinville (Macoupin County) and Hillsboro 
(Montgomery County), Illinois, while the Palmer Bank has offices in Palmer 
and Taylorville (Christian County), and in Chatham (Sangamon County), 
Illinois. While the local economies of this area are somewhat diverse, the 
primary industry of the four-county area is agriculture.  The four counties 
served by CNB include some of the richest and most fertile soil in the 
Midwest and the primary agricultural commodities are corn and soybeans.

     The city of Carlinville has a population of approximately 5,500 and is 
the county seat of Macoupin County.  While agriculture is a primary focus in 
Macoupin County, there are some other non-agricultural employers located in 
Carlinville.  Monterey Coal Company employs 330 people, Carlinville Area 
Hospital employs 185 people, Curry Ice and Coal Company employs 175 people, 
Lippold and Arnett employs 135 people, Prairie Farms Dairy employs 128 people 
and the Carlinville School District employs 100 people.

     The city of Hillsboro has a population of approximately 4,500 and is the 
county seat of Montgomery County.

                                        43

<PAGE>

     The city of Taylorville has a population of approximately 11,500 and is 
the county seat of Christian County.  The town of Palmer, also located in 
Christian County, has a population of 275.  Palmer has few employers and most 
of the residents in the surrounding community are engaged in agriculture.

     The city of Chatham has a population of 8,000 and is located in Sangamon 
County, approximately five miles south of the affluent and expanding market 
of Springfield, the Illinois state capital.  Chatham primarily serves as a 
"bedroom community" for the nearby city of Springfield.  Most of the 
residents of Chatham are employed by state government agencies and other 
businesses located in and around Springfield.  The local economy in Chatham 
is very stable because of the large number of stable jobs generated by state 
government.  Springfield also has a relatively large number of employment 
opportunities in the health care, education and insurance fields.

GROWTH STRATEGY 
     
     CNB seeks to diversify both its market area and asset base while 
increasing profitability through selected acquisitions and internal 
expansion.  CNB's goal, as reflected by its acquisition policy, is to expand 
through the acquisition of established financial service organizations, 
primarily commercial banks or thrifts, to the extent suitable candidates can 
be identified and acceptable business terms negotiated.  Although not 
actively seeking additional acquisitions at this time, CNB intends to 
continue exploring opportunities for acquisitions and expansion as they may 
arise.  It is not presently known whether, or on what terms, such discussions 
would result in further acquisitions.

     Any interest CNB would have in additional acquisitions or expansion 
would most likely be focused on traditional community banks and thrifts 
located in stable and growing areas located in central and southwestern 
Illinois.  At this time, a large number of such financial institutions are 
located within this geographic area.  It is possible, however, that as a 
result of consolidation within the banking industry generally, as well as in 
CNB's current market areas, CNB may in the future look beyond these 
geographic areas for acquisition opportunities.  In addition to price and 
terms, other factors considered by CNB in determining the desirability of an 
acquisition candidate are financial condition, earnings potential, quality of 
management, market area and competitive environment. 

     The CNB Board may in the future consider establishing branches, loan 
production offices or other business facilities as a means of expanding its 
presence in current or new market areas.  The CNB Board may also investigate 
expansion into other lines of business closely related to banking if it 
believes these lines could be profitable without undue risk to CNB and if CNB 
can be competitive.

     CNB does not currently have any definite understandings or agreements 
for any acquisitions material to CNB.  However, CNB anticipates that it will 
continue to grow in the future either internally, by acquisition or a 
combination of both. Notwithstanding such anticipation, there is no assurance 
that any further acquisitions will be made or that any branches or other 
offices will be established.

OPERATING STRATEGY
     
     Corporate policy, strategy and goals are established by the CNB Board.  
Pursuant to CNB's philosophy, operational and administrative policies for the 
CNB Banks are also established by CNB.  Within this framework, each of the 
CNB Banks focuses on providing personalized services and quality products to 
its customers to meet the needs of the communities which it serves. 

     CNB operates its banking subsidiaries as traditional community banks 
with conveniently located facilities and professional, highly motivated 
staffs which are active in the communities in which they are located.  CNB 
focuses on long-term relationships with customers and provides individualized 
quality service. As part of its community banking approach, CNB encourages 
officers of the CNB Banks to actively participate in community organizations. 
In addition, within credit and rate of return parameters, CNB attempts to 
ensure that each of the CNB Banks meets the credit needs of its communities 
and invests in local municipal obligations.

                                        44

<PAGE>

     CNB uses a variety of marketing strategies to attract and retain 
customers, with a particular emphasis on a strong sales culture within the 
CNB Banks and an outside officer calling program.  Officers of each of the 
CNB Banks regularly call on customers and potential customers of the 
institutions to maintain and develop deposit and other special service 
relationships, including cash management, employee benefit plan 
administration and lock box and fiduciary services.

     CNB has an internal data processing division and has attempted to remain 
at the forefront of the banking industry in new technological innovations.  
CNB believes that retaining control of its data processing leads to decreased 
operating costs, more effective service to its customers and increased 
efficiencies.  To provide a high level of customer service and to manage 
effectively its growth, acquisition and operating strategies, CNB also 
focuses on continued improvement of the CNB Banks' internal operating systems.

LENDING ACTIVITIES
     
     GENERAL

     The CNB Banks provide a broad range of commercial and retail lending 
services to corporations, partnerships, individuals and government agencies.  
These credit activities include agricultural, commercial, residential real 
estate and installment loans, as well as loan participations, leasing, lines 
of credit and purchases of municipal obligations.

     The CNB Banks aggressively market their services to qualified lending 
customers. Lending officers actively solicit the business of new borrowers 
entering their market areas as well as long-standing members of the banks' 
respective business communities.  Through professional service and 
competitive pricing, the CNB Banks have been successful in attracting new 
agricultural and commercial lending customers.  The CNB Banks also actively 
pursue consumer lending opportunities. Through convenient locations, 
advertising and customer communications, the CNB Banks have been successful 
in capitalizing on the credit needs of their market areas.

     COMMERCIAL LOANS

     The CNB Banks have a strong commercial loan base and the Carlinville 
Bank in particular continues to be an active commercial lender in Macoupin 
County.  The CNB Banks' areas of emphasis include, but are not limited to, 
loans to wholesalers, manufacturers, building contractors, developers, 
business services companies and retailers.  The CNB Banks provide a wide 
range of business loans, including lines of credit for working capital and 
operational purposes and term loans for the acquisition of equipment and 
other purposes.  Collateral for these loans generally includes accounts 
receivable, inventory, equipment and real estate.  Loans may be made on an 
unsecured basis if warranted by the overall financial condition of the 
borrower.  Terms of commercial business loans generally range from one to 
five years.  The majority of the CNB Banks' commercial business loans have 
floating interest rates or reprice within one year.

     The primary repayment risk for commercial loans is the failure of the 
business due to economic or financial factors.  In most cases, the CNB Banks 
have collateralized these loans and/or taken personal guarantees to help 
assure repayment.

     As the credit portfolios of the CNB Banks have continued to grow, 
several changes have been made in their lending departments resulting in an 
overall increase in these departments' skill levels.  Loan review personnel 
and commercial lenders interact with their respective boards of directors 
each month.  CNB has also instituted a separate loan review function to 
analyze credits of the CNB Banks.  Management has attempted to identify 
problem loans at an early stage and to aggressively seek a resolution of 
these situations.  The result has been a significantly below average level of 
problem loans compared to the CNB Banks' industry peer groups.  SEE 
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS OF CARLINVILLE NATIONAL BANK SHARES, INC.--NONPERFORMING LOANS 
AND ASSETS."

     AGRICULTURAL LOANS

     The CNB Banks are active lenders to the agricultural industry.  
Agricultural loans continue to be emphasized by each of the CNB Banks due to 
their concentration of customers in rural markets.  Agricultural loans 
currently represent over 30% of CNB's consolidated loan portfolio.  The CNB 
Board closely monitors its agricultural loan concentration. In connection 
with their agricultural lending, the CNB Banks have remained close to their 
traditional geographical market areas.  The majority of the CNB Banks' 
outstanding agricultural operating and real estate loans primarily relate to 
ventures within 20 miles of their main or branch offices. 

     Agricultural loans and direct financing leases, many of which are 
secured by crops, machinery and real estate, are provided to finance capital 
improvements and farm operations as well as acquisitions of livestock and 
machinery.  The loan departments of the CNB Banks, work closely with all 
agricultural customers, including companies and individual farmers, and 
assist in the preparation of budgets and cash flow projections for the 
ensuing crop year.  These budgets and cash flow projections are monitored 
closely during the year and reviewed with agricultural customers at least 
once a year.  In addition, the CNB Banks work closely with governmental 
agencies, including the Farmers Home Administration, to assist agricultural 
customers in obtaining credit enhancement products such as loan guaranties.

     REAL ESTATE MORTGAGE LOANS

     Mortgage lending has been a focal point of the CNB Banks as each 
continues to build its real estate lending business.  In 1997, CNB 
established a mortgage banking department inside the CNB Banks to originate 
mortgage loans for sale in the secondary market.  Servicing rights are not 
retained on the loans originated and sold.  In general, mortgage activity in 
1997 was active as low interest rates induced a large number of home owners 
to refinance existing homes and an equally large number of first time buyers 
to acquire or construct homes.  In 1997, the mortgage banking departments 
inside the CNB Banks originated and sold into the secondary market 
approximately $9.4 million of mortgage loans.

     CONSUMER LENDING

     The CNB Banks' consumer lending departments provide all types of 
consumer loans including motor vehicle, home improvement, home equity, 
student loans, signature loans and small personal credit lines.  The CNB 
Banks have entered into a contract with a non-affiliated third party to 
provide credit card processing for their operations.  Through this program, 
the CNB Banks have increased profits and augmented the cross-selling 
opportunities by increasing their marketing bases.

OTHER SERVICES
     
     CTS was originally established in 1995 to provide tax return preparation 
services for the local customers of the Carlinville Bank.  Since that time, 
CTS has expanded to provide certain bookkeeping services for local clients as 
well. CTS is located in the main office of the Carlinville Bank in 
Carlinville.  In 1997, CTS reported net income of $4,718.

     The CNB Banks also offer to their customers full service brokerage 
services through a third party brokerage house.  These services are currently 
offered through CNB's offices in Carlinville and Hillsboro, and CNB is 
considering expanding operations to the offices of the Palmer Bank in 
Taylorville, Palmer and Chatham, Illinois.

COMPETITION
     
     CNB encounters competition in all areas of its business pursuits. In 
order to compete effectively, to develop its market base, to maintain 
flexibility and to move in pace with changing economic and social conditions, 
CNB continuously refines and develops its products and services.  The 
principal methods of competition in the financial services industry are 
price, service and convenience.

                                        46

<PAGE>

     The CNB Banks' combined market area is highly competitive.  There are 
approximately thirty-six other commercial banks that currently operate 
banking offices in the four-county area in which the CNB Banks primarily 
operate.  In addition, many other financial institutions based in the 
communities surrounding these counties also actively compete for customers 
within CNB's market areas. The CNB Banks also face competition from finance 
companies, insurance companies, mortgage companies, securities brokerage 
firms, money market funds, loan production offices and other providers of 
financial services.

     CNB competes for loans principally through the range and quality of the 
services it provides, interest rates and loan fees.  CNB believes that its 
long-standing presence in the communities it serves and personal service 
philosophy enhance its ability to compete favorably in attracting and 
retaining individual and business customers.  CNB actively solicits 
deposit-related clients and competes for deposits by offering customers 
personal attention, professional service and competitive interest rates.

EMPLOYEES
     
     At December 31, 1997, CNB employed approximately 85 full-time equivalent 
employees.  CNB places a high priority on staff development which involves 
extensive training, including customer service training.  New employees are 
selected on the basis of both technical skills and customer service 
capabilities.  None of CNB's employees are covered by a collective bargaining 
agreement with CNB.  CNB offers a variety of employee benefits and management 
considers its employee relations to be excellent.

PROPERTIES
     
     The principal offices of CNB are located in the Carlinville Bank's main 
office at West Side Square, Carlinville, Illinois 62626.  This office is 
owned by the Carlinville Bank and consists of a two-story brick building 
constructed in the 1920's, all of which is occupied by the Carlinville Bank, 
CNB and CTS.  The Carlinville Bank has one other banking office located in 
Hillsboro, Illinois. The Carlinville Bank leases this facility under a five 
year lease.

     The Palmer Bank owns its main office located at 620 North Webster 
Street, in Taylorville, Illinois.  The Palmer Bank has two other facilities, 
one located in Palmer and the other located in Chatham, Illinois.  The Palmer 
Bank owns its office in Palmer and leases its office in Chatham under a two 
year lease.

     The CNB Board is comprised of eight members, with directors serving one 
year terms.  Mr. James T. Ashworth is the nephew of Ms. Joie L. Russell.  
There are no other family relationships among any of the directors or 
executive officers of CNB or the CNB Banks.

     CNB directors do not receive separate compensation for their services on 
the CNB board.  Each CNB director is also a director of the Carlinville Bank, 
and in such capacity receives a monthly retainer of $250, and also receives 
$250 for each board meeting attended and $100 for each committee meeting 
attended.

     COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION
      DECISIONS

     CNB does not have a Compensation Committee or other board committee 
performing equivalent functions.  Compensation decisions are determined by a 
committee of the whole CNB Board.  Each of the directors of CNB also serves 
as a director of the Carlinville Bank, and Messrs. Ashworth and Davis serve 
as the President and Chief Executive Officer and the Executive Vice 
President, respectively, of CNB and the Carlinville Bank.

     CNB PROFIT SHARING PLAN

     The CNB Profit Sharing Plan is a profit sharing plan established under 
Section 401(k) of the Code.  Under the CNB Profit Sharing Plan, participants 
are permitted to make salary reduction contributions to the plan in an amount 
which does not exceed a specific dollar amount determined by the Internal 
Revenue Service.  CNB has agreed to contribute for each participant a 
matching contribution equal to 100% of the participant's eligible 
contributions to a maximum of 5% of such participant's annual salary.  In 
addition, CNB may make an annual discretionary contribution to each 
participant's account.

     CNB DIRECTORS' INCENTIVE DEFERRAL PLAN

     Effective December 1997, the Carlinville Bank adopted an Incentive 
Deferral Plan (the "Carlinville Bank Deferral Plan") for certain of its 
directors, allowing such directors to defer their current compensation earned 
as directors, with the Carlinville Bank agreeing to pay to such directors, or 
their designated beneficiaries or survivors, the total amount of deferred 
compensation plus accumulated interest at or following retirement.  Under the 
CNB Deferral Plan, interest is added to the accumulated deferred compensation 
at a periodic compound rate equal to the Carlinville Bank's return on equity 
before such interest charges.  The directors are expected to continue to 
render their normal service as directors to the Carlinville Bank from the 
date of the CNB Deferral Plan's inception until retirement.

     The CNB Deferral Plan stipulates that, upon disability, termination, or 
death prior to retirement, the affected director (or his or her designated 
beneficiaries or survivors) would be vested in the total deferred 
compensation accumulated to that date, plus compound interest.  Payments 
under the CNB Deferral Plan may be made in a lump sum or periodically over a 
specified time period, with interest.

     To fund the individual agreements with each director covered under the 
CNB Deferral Plan, the Carlinville Bank has purchased flexible premium 
universal life insurance policies on the lives of such directors, (payable 
upon death to the Carlinville Bank), and paid a single one-time premium at 
the inception of the policies

                                        49
<PAGE>


totaling $910,000.  No other payments or premiums are required of
the Carlinville Bank.  Each life insurance policy has a cash surrender value
feature which allows the Carlinville Bank to receive an amount in cash upon
cancellation or lapse of the policy.

LEGAL PROCEEDINGS

     From time to time, one or more of CNB's subsidiaries, including the CNB 
Banks, becomes involved as plaintiff or defendant in various legal actions 
arising in the normal course of their respective businesses.  While the 
ultimate outcome of these various legal proceedings cannot be predicted with 
certainty, it is the opinion of CNB's management that there are no material 
pending legal proceedings to which CNB or any of its subsidiaries is a party 
other than such ordinary routine litigation the resolution of which would not 
reasonably be expected to have a material effect on CNB's consolidated 
financial position.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Certain of the directors and officers of CNB and the CNB Banks, and some 
of the corporations and firms with which these individuals are associated, 
are customers of the CNB Banks or CTS in the ordinary course of business, or 
are indebted to one or more of the CNB Banks for loans of $60,000 or more, 
and it is anticipated that they will continue to be customers of, and 
indebted to, one or more of such CNB Banks in the future.  The amount of 
indebtedness of CNB's directors and officers is equal to approximately 3.5% 
of stockholders' equity at December 31, 1997.  All such loans, however, were 
made in the ordinary course of business, did not involve more than the normal 
risk of collectibility or present other unfavorable features, and were made 
on substantially the same terms, including interest rates and collateral, as 
those prevailing at the same time for comparable loans made by the CNB Banks 
in transactions with unaffiliated persons.
                                          
                        MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF
                       CARLINVILLE NATIONAL BANK SHARES, INC.

     The following presents management's discussion and analysis of the 
consolidated financial condition and results of operations of CNB for each of 
the years in the three-year period ended December 31, 1997 and the three 
months ended March 31, 1998 and 1997.  This discussion and analysis is 
intended to review the significant factors affecting the financial condition 
and results of operations of CNB, and provides a more comprehensive review 
which is not otherwise apparent from the consolidated financial statements 
alone.  This discussion should be read in conjunction with "SELECTED 
CONSOLIDATED FINANCIAL DATA", and CNB's consolidated financial statements and 
the notes thereto and other financial data appearing elsewhere in this Proxy 
Statement-Prospectus.

OVERVIEW

     Total assets increased to $197,180,890 at December 31, 1997, while loans 
and deposits increased to $111,925,209 and $167,614,872, respectively at the 
end of 1997, primarily as a result of the acquisitions of the Hillsboro 
Branch and Lincoln Trail.  CNB has worked to affect the synergies of a larger 
organization, while maintaining the personal service of a local community 
bank at each of its banking facilities.  At December 31, 1997, the increases 
achieved in assets, loans and deposits had not yet translated into increased 
earnings for CNB.  Net income for the year ended December 31, 1997 was 
$1,850,678, which represented a decrease of $66,073 or 3.4% from the 1996 net 
income of $1,916,751.  1996 net income was $87,658 (4.8%) higher than the 
$1,829,093 recorded for the year ended December 31, 1995.  Earnings per share 
for the years ended December 31, 1997, 1996 and 1995 were $9.93, $10.31 and 
$9.84, respectively.  CNB's earnings in 1997 were impacted by the 
amortization of intangible assets incurred in connection with the Hillsboro 
Branch and Lincoln Trail acquisitions. Additionally, the two acquisitions 
lowered CNB's loan-to-deposit ratio, as discussed further below.  The average 
loan-to-deposit ratio was 76.8% in 1995, 74.1% in 1996 and 64.1% in 1997.  

     CNB plans to increase the loan-to-deposit ratio to augment future 
earnings. Additionally, the acquisition of Lincoln Trail involved a bank 
which experienced severe asset quality problems during the two years prior to 
acquisition by CNB. Considerable time and effort was spent by CNB and Palmer 
Bank management to resolve those problems in 1997, and CNB management 
believes that a substantial portion of the problems are now resolved.

<PAGE>

     CNB's results for the first quarter of 1998 provide an indication that 
the efforts of CNB management in affecting synergies and cleaning up the past 
problems at Palmer Bank are beginning to show results.  Net income for the 
three months ended March 31, 1998 was $579,541 ($3.11 per share), up $150,737 
(35.2%) from the $428,804 ($2.30 per share) recorded for the three months 
ended March 31, 1997.  The primary contributor to this improvement was the 
increased level of loans maintained during the first quarter of 1998.  The 
average loan-to-deposit ratio for the first quarter of 1998 was 66.8%, as 
compared with the 62.7% average level for the first quarter of 1997.  
Additionally, as further discussed below, CNB "cashed in" a portion of the 
appreciation achieved on a mutual fund investment held at the holding 
company, resulting in a gain on the sale thereof of approximately $135,000.  
The net proceeds of this sale of $330,000 were used to inject additional 
capital into Palmer Bank.

     CNB continues to maintain a strong capital base, with consolidated Tier 
1 regulatory capital of $16,052,165 and $16,700,000 at December 31, 1997 and 
March 31, 1998, respectively, or 12.49% and 13.38%, respectively, of 
risk-based assets.  Cash dividends continued to increase, growing 14.6% in 
1995 to $2.35 per share, 8.5% in 1996 to $2.55 per share, and 7.8% in 1997 to 
$2.75 per share. Book value also increased during the three-year period, 
growing 9.8% in 1995 to $92.33 per share, 8.3% in 1996 to $99.98, and 9.6% in 
1997 to $109.56.  Book value continued to grow in the first quarter of 1998, 
increasing to $112.62 at March 31, 1998.  Following are certain other ratios 
generally followed in the banking industry for CNB for each of the years in 
the three-year period ended December 31, 1997 and the three months ended 
March 31, 1998 and 1997.

     CNB's net interest income increased by $1,348,628 (27.2%) to $6,312,485 
for the year ended December 31, 1997 from $4,963,857 for the year ended 
December 31, 1996, which was $149,317 (3.1%) higher than the net interest 
income for the year ended December 31, 1995.  During this period, CNB's net 
interest margin declined from 4.25% in 1995, to 4.20% in 1996, to 3.67% in

$181,103,893.  Average earning assets for 1996 increased by $4,166,664 (3.4%) 
to $125,079,236 from $120,912,572 for 1995.  The percentage of average 
earning assets comprised of loans, which is CNB's highest earning asset, 
declined during this same three-year period.  In 1995, average loans as a 
percentage of average earning assets was 64.1%.  In 1996, this percentage 
declined to 62.8%, and in 1997, after completing the two acquisitions, the 
percentage declined to 57.8%. With an average tax-effective yield of 8.83% 
earned on loans during 1997, compared with a weighted average tax-effective 
yield of 6.34% earned on other interest-earning assets in 1997, for every 
$1,000,000 which would have been channeled into loans instead of other 
interest-earning assets, CNB's net interest income would have increased 
approximately $25,000.  Accordingly, a shift of $10,000,000 from investment 
securities to loans would have equated to an increase in pretax income of 
$250,000 on an annual basis.  Increasing the percentage of higher yielding 
loans to total assets has been a CNB goal since the consummation of the two 
acquisitions.

     With the acquisition of the Hillsboro Branch, CNB assumed approximately 
$24.4 million of deposits and acquired approximately $318,000 of loans.  The 
net cash received of approximately $22,000,000 was invested at that time 
primarily in taxable debt securities.  Accordingly, the average taxable 
securities increased from $23,615,134 for 1995 to $27,424,164 for 1996 to 
$53,085,041 for 1997. Interest rates earned on such investments remained 
relatively stable for this period, at 5.83% for 1995, 5.92% for 1996, and 
6.05% for 1997.

     With the acquisition of Lincoln Trail, CNB acquired an organization with 
total assets of $35.4 million, loans of $21.7 million, and deposits of $33.9 
million. This acquisition accounted for the majority of CNB's growth in 
average loans in 1997.  Average loans grew $26,161,001 (33.3%) to 
$104,656,135 for the year ended December 31, 1997, after remaining relatively 
stable in 1996 when compared to 1995.  Average loans grew only $950,812 
(1.2%) to $78,495,134 for the year ended December 31, 1996 from the 
$77,544,322 of average loans for the year ended December 31, 1995.  Rates 
earned on loans were 8.59% in 1995, 8.88% in 1996, and 8.83% in 1997.  The 
rate increase achieved on loans in 1996 was consistent with the general level 
of interest rates in the national economy.  While the general level of 
interest rates in the national economy was up only slightly in 1997, CNB 
actually experienced a slight decrease, primarily due to the increased level 
of nonperforming loans which CNB inherited as part of the Lincoln Trail 
acquisition.  SEE " -- CREDIT RISK MANAGEMENT."

     CNB's level of Federal funds sold is directly attributable to the level 
of securities sold under repurchase agreements maintained with certain 
customers of the Carlinville Bank.  These customers invest on a short-term 
basis, generally overnight, in securities sold under repurchase agreements by 
the Carlinville Bank, thus providing a return on their excess funds.  These 
funds are invested by the Carlinville Bank in Federal funds sold to match the 
maturities of the repurchase agreements, with the Carlinville Bank generally 
earning approximately 50 basis points on each transaction.  As the excess 
funds of these customers fluctuate, so too has CNB's overall level of Federal 
funds sold.  The acquisitions of Lincoln Trail and the Hillsboro Branch 
facility have also provided additional liquidity.

     Following is a summary of the average balances and weighted average 
rates earned or paid on Federal funds sold and securities sold under 
repurchase agreements for each of the years in the three-year period ended 
December 31, 1997:

     CNB believes this cash management service will continue at a consistent 
level.  

     CNB experienced an increase in its cost of funds during the three-year 
period ended December 31, 1997.  The average cost of funds increased each 
year, from 4.53% in 1995, to 4.70% in 1996 to 4.75% in 1997.  With the 
acquisitions of the Hillsboro Branch and Lincoln Trail, the level of 
interest-bearing liabilities also increased significantly.  In 1997, average 
total interest-bearing deposits increased $53,026,637 (56.2%) to 
$147,444,518, while growing $4,655,370 (5.2%) in 1996 to $94,417,881.  The 
acquisition of the Hillsboro Branch in late 1996 added approximately $24 
million of interest-bearing deposits, consisting of the following types of 
deposits (in thousands):

     Since the acquisition of the Hillsboro Branch, CNB has experienced 
minimal deposit run-off from this branch.

     The CNB Banks have experienced a general shift in deposits similar to 
most Midwestern financial institutions, with certificates of deposit under 
$100,000 comprising a growing proportion of its deposits.  Following is an

</TABLE>

     The acquisitions of the Hillsboro Branch and Lincoln Trail increased the 
percentage of deposits comprising certificates of deposit under $100,000.  
Such deposits were 65.0% of the Hillsboro Branch deposits assumed and 55.2% 
of the Palmer Bank deposits acquired.  These changes in the composition of 
CNB's deposits have increased the overall cost of funds.

     In addition to the interest paid on securities sold under repurchase 
agreements, CNB also incurred interest on other short-term borrowings of 
$63,483, $20,337 and $38,757 for the years ended December 31, 1997, 1996 and 
1995, respectively. These generally consist of borrowings under the Federal 
Reserve Bank's treasury, tax and loan note option.  Additionally, in the 
first half of 1997, CNB borrowed $1,750,000 from an unaffiliated financial 
institution for approximately three months to temporarily assist in funding 
the Lincoln Trail acquisition.  This short-term borrowing was repaid from 
additional dividends paid by the Carlinville Bank to CNB in April, 1997.

     The following table sets forth, on a tax-equivalent basis for the 
periods indicated, a summary of the changes in interest income and interest 
expense resulting from changes in volume and changes in yield/rates:

     FIRST QUARTER COMPARISON

     Net interest income for the three months ended March 31, 1998 increased 
$137,488 (9.3%) to $1,615,182 from the $1,477,694 recorded for the three 
months ended March 31, 1997.  The net interest margin increased 17 basis 
points to 3.72% for the first quarter of 1998 from the net interest margin of 
3.55% for the first quarter of 1997.

     Average earning assets for the first quarter of 1998 increased 
$5,735,601 (3.2%) to $185,841,874 from the average earning assets of 
$180,106,273 for the first quarter of 1997.  The percentage of average 
earning assets comprised of loans was 61.1% for the first quarter of 1998, 
compared with 56.2% for the first quarter of 1997.  This increase in loans, 
resulting primarily from the increased lending capacity resulting from the 
acquisitions, has fueled CNB's strong first quarter performance.  
Additionally, increased lending is now a focal point for Palmer Bank 
management, after spending most of 1997 cleaning up the past problems 
experienced at that institution.  CNB management expects the trend in loan 
growth to continue in the immediate future, as the local economies in the 
various markets served by the CNB Banks continue to be strong.

     The average level of taxable investment securities declined $3,270,002 
(6.3%) in the first quarter of 1998 to $48,594,520 from the average balance 
of $51,864,522 for the first quarter of 1997.  Proceeds from maturing 
securities were used to fund loan growth.  The level of average securities 
exempt from Federal income taxes

remained relatively stable, with an average balance of $12,047,223 for the 
first quarter of 1998 as compared with an average balance of $12,100,287 for 
the first quarter of 1997.

     Average Federal funds sold for the first quarter of 1998 declined 
$3,242,123 (21.7%) to $11,703,966 from the average level of $14,946,089 for 
the first quarter of 1997.  As discussed above, the average levels of Federal 
funds sold are affected by the level of excess cash maintained by customers 
of the Carlinville Bank who purchase securities under repurchase agreements 
for cash management purposes.  The average of securities sold under 
repurchase agreements for the first three months of 1998 declined $1,639,156 
(16.7%) from the average for the corresponding three-month period in 1997 of 
$9,804,909.  The remaining reduction in average Federal funds sold resulted 
from funding additional loans.

     Average interest-bearing deposits for the first quarter of 1998 
increased $7,896,531 (5.4%) to $153,419,196, from the average level of 
$145,522,665 for the first quarter of 1997.  CNB experienced an increase in 
deposits moving from financial institutions which have been sold or are in 
the process of being sold to larger, non-locally based financial 
institutions, as customers are seeking more personal service than that 
offered by the larger banking institutions. CNB's cost of funds continued to 
increase, as the trend in the mix of deposits discussed above continued.

     The percentage of the average of each deposit caption to total average 
deposits for the three-months ended March 31, 1998 and 1997 was as follows:

     With certificates of deposit comprising over 60% of the deposit 
portfolio in the first quarters of both 1998 and 1997, CNB's cost of funds 
increased to 4.85% for the first quarter of 1998, compared with 4.48% for the 
first quarter of 1997. Price competition for such deposits continued to be 
intense, as the average rates paid on certificates of deposit increased 39 
basis points to 5.67% for the first quarter of 1998, compared with 5.28% for 
the first quarter of 1997, despite the fact that the overall level of 
interest rates in the economy showed little change during this period.

     The following table sets forth, on a tax equivalent basis for the first 
quarters of 1998 and 1997, a summary of the changes in interest income and 
interest expense resulting from changes in volume and changes in 
yields/rates.

     PROVISION FOR POSSIBLE LOAN LOSSES

     The provision for possible loan losses charged to earnings for the year 
ended December 31, 1997 and the three months ended March 31, 1998 totaled 
$170,000 and $30,000, respectively, which were the first such provisions 
recorded by CNB for several years.  As a one-bank holding company prior to 
1997, CNB's net charge-off ratio was historically much lower than its peer 
group.  Accordingly, the level of the reserve for loan losses was maintained 
at a lower level as well. The purchase of Lincoln Trail, coupled with the 
occurrence of one significant charge-off of $172,000 on a problem commercial 
borrower in 1997, led to the additions to the reserve for loan losses.  A 
more detailed presentation of asset quality and the reserve for possible loan 
losses is included in "CREDIT RISK MANAGEMENT," below.

     NONINTEREST INCOME

     Total noninterest income for the year ended December 31, 1997 increased 
$608,430 (100.5%) to $1,213,953 from the $605,523 recorded in 1996, which was 
an increase of $13,573 (2.3%) over the $591,950 recorded in 1995.  Several 
factors caused these year-to-year increases, including the following:

     -  1997 results included the operations of the Palmer Bank from January 24,
        1997 forward and the Hillsboro Branch for the entire year.  Accordingly,
        the increases achieved in 1997 in service 


                                     57
<PAGE>

        charges on deposit accounts and other noninterest income were primarily
        a result of the expanded operations of CNB.

     -  In 1997, the Carlinville Bank introduced a fee-based commercial checking
        product which has proven quite successful.  This program and the 
        expanded operations resulted in increases in service charges on deposit
        accounts of $199,713 (69.1%) to $488,934 for the year ended December 
        31, 1997.

     -  In 1997, the Palmer Bank received approximately $32,000 from an 
        insurance claim.  This claim receipt and the expanded CNB's operations 
        resulted in increases of $112,185 (57.3%) in other noninterest income 
        to $307,933 for the year ended December 31, 1997.

     -  Income from fiduciary activities at the Carlinville Bank increased 
        $50,351 (47.9%) in 1997 to $155,458, from the $105,107 recorded in 1996,
        which was down $20,234 (16.1%) from the $125,341 recorded in 1995.  A 
        significant determinant in the level of trust earnings each year is the
        amount of estate work performed in any given year.  In 1996, no estate
        work was performed, which caused the reduction of earnings in that year.
        In 1997, additional estate work was received and the Carlinville Bank's
        fee structure was also revised upward, resulting in increased trust 
        income for the year.

     -  In 1997, CNB established a mortgage banking department, which originates
        loans for sale in the secondary market.  Approximately $9.4 million 
        of loans were originated and sold in 1997, resulting in net gains and 
        fees totaling $68,455.  CNB does not retain servicing on these 
        mortgages.

     -  CNB had net security sale gains of $193,173, $15,447 and $6,897 for the
        years ended December 31, 1997, 1996 and 1995, respectively.  $1,960 of
        the 1997 gains and the total gains in 1996 and 1995 resulted from early
        calls on securities held by the CNB Banks.  Approximately $9,000 of 
        the net gains in 1997 were recorded at the Palmer Bank shortly after
        CNB's acquisition thereof, on sales made to restructure the portfolio
        in line with CNB's investment strategies.  The remaining $182,000 of 
        gains were recorded at the holding company, primarily the result of CNB
        realizing some of the appreciation earned on a mutual fund investment,
        and reinvesting the proceeds in a similar fund.  In late 1995 and 
        throughout 1996, CNB invested a total of $1,000,000 in a mutual fund
        comprised of regional bank stocks.  With the banking consolidation and
        strong market performance by regional banks occurring during the past
        few years, these funds appreciated significantly.  By year-end 1996,
        the fund had appreciated to $1,215,719.  By June 1997, the fund had 
        further appreciated to $1,446,915, at which time CNB sold a portion of
        the fund to invest $450,000 in a similar fund, recording a gain of 
        $170,483 in the process.  These funds, which are included in 
        available-for-sale securities, continued to appreciate throughout the
        remainder of 1997, and had a value at December 31, 1997 of $1,919,603.

     Total noninterest income increased $199,273 (91.2%) to $417,761 in the 
first quarter of 1998 from the $218,488 recorded in the first quarter of 
1997.  The primary factor for this increase in 1998 was the sale of an 
additional portion of the regional bank stock mutual fund investment.  During 
the first quarter of 1998, CNB sold  $330,000 of the fund investment and 
injected the proceeds into Palmer Bank to increase its capital.  CNB recorded 
a gain of $134,428 on the sale.  Meanwhile, the regional bank stock mutual 
fund investment continued to appreciate in value during the first quarter of 
1998, and had a value at March 31, 1998 of $1,704,769.

     The increase in noninterest income in the first quarter of 1998 was also 
affected by the establishment of a mortgage banking department in the second 
quarter of 1997.  Net gains recorded on loans sold in the secondary market 
were $24,139 for the first quarter of 1998, with no corresponding activity 
for the first quarter of 1997.  Additionally, CNB operations for the first 
quarter of 1998 included 24 more days of Palmer Bank's operations, as 
compared with the first quarter of 1997.


                                      58

     NONINTEREST EXPENSE

     Noninterest expense increased $2,084,849 (72.0%) for the year ended 
December 31, 1997 to $4,981,282 from the 1996 level of $2,896,433, which was 
little changed from the $2,855,371 of noninterest expense recorded in 1995.  
The primary increase in all noninterest expense categories was the result of 
the expanded operations of CNB with the acquisitions of the Hillsboro Branch 
and Lincoln Trail.  Amortization of intangible assets resulting from these 
acquisitions totaled $261,930 in 1997.

     Noninterest expense increased $65,098 (5.7%) to $1,197,320 for the first 
quarter of 1998, as compared with the corresponding period of 1997.  The 
primary reason for this increase was the overall effect of having 24 more 
days of Palmer Bank's operations in the first quarter of 1998, as compared 
with the first quarter of 1997.  Additionally, the first three months of 1998 
included salaries and benefits of an upgraded management staff at Palmer Bank 
and the mortgage banking department operations.

     INCOME TAXES

     Applicable income taxes declined $231,718 (30.6%) for the year ended 
December 31, 1997 to $524,478 from the $756,196 recorded for 1996.  The 1996 
tax expense was consistent with that incurred for the year ended December 31, 
1995 of $722,026.  The effective tax rates for 1997, 1996 and 1995 were 
22.1%, 28.3% and 28.3%, respectively.  The decrease in tax expense in 1997 
was attributable to a lower level of taxable income, plus a reduced state 
income tax expense, resulting from the purchase of a significant level of 
state tax-exempt U.S. agency securities in late 1996 and early 1997.

     Applicable income taxes increased $90,926 (67.3%) to $226,082 for the 
three months ended March 31, 1998, from the $135,156 recorded for the 
corresponding three-month period in 1997.  The effective tax rates for the 
three months ended March 31, 1998 and 1997 were 28.1% and 24.0%, 
respectively.  The increase in income taxes in 1998 was due to a higher level 
of taxable income, and the reduction in the level of state tax-exempt U.S. 
agency securities on hand in 1998, several of which were called or matured in 
the fourth quarter of 1997.

FINANCIAL CONDITION

     Total assets of CNB grew $47,083,699 (31.4%) to $197,180,890 at December 
31, 1997, from $150,097,191 at December 31, 1996.  Approximately $37.4 
million of this increase has occurred as a result of the acquisition of 
Lincoln Trail. Total assets grew an additional $4,063,531 (2.1%) to 
$201,244,421 at March 31, 1998, primarily due to continued growth in deposits 
at the CNB Banks.

     Total deposits increased $40,775,587 (32.1%) to $167,614,872 at December 
31, 1997 from $126,839,285 at December 31, 1996.  Approximately $33.9 million 
of this increase occurred as a result of the acquisition of Lincoln Trail.  
The remaining increase of approximately $6.9 million was due to normal 
internal growth plus the addition of public deposits from Montgomery County.  
With the Hillsboro Branch acquisition in 1996, CNB added a location in 
Montgomery County, providing the ability to become a bidder for the County's 
deposits.  As a result, public fund deposits increased over $4 million at the 
Carlinville Bank for the year ended December 31, 1997.  Total deposits 
continued to grow in the first quarter of 1998, increasing $5,361,736 (3.2%) 
to $172,976,608 at March 31, 1998.  This growth resulted primarily from an 
influx of deposits of customers from larger regional banks affected by the 
consolidation in the banking industry, as such customers looked for a bank 
with more personal service.

     Short-term borrowings increased $4,255,289 (115.7%) to $7,932,881 at 
December 31, 1997 from $3,677,592 at December 31, 1996, and then decreased 
$2,224,720 (28.0%) in the first quarter of 1998 to $5,708,161 at March 31, 
1998.  These balances tend to have significant fluctuations depending upon 
the cash levels of the customers which use the cash management facilities of 
the Carlinville Bank through the purchase of securities under repurchase 
agreements.  CNB believes these companies experienced strong operations in 
1997, and thus far in 1998, resulting in excess cash.  The level of Federal 
funds sold generally tracks with the level of securities sold under 
repurchase agreements.  Federal funds sold increased $4,685,000 (125.1%) in 
1997 to

$8,429,000 at December 31, 1997 from $3,744,000 at December 31, 1996. The 
level of Federal funds sold at March 31, 1998 did not show a decrease as did 
short-term borrowings, with the balance at March 31, 1998 of $13,975,000 
representing an increase of $5,546,000 (65.8%) from December 31, 1997.  The 
increase in deposits and investment maturities more than offset the decrease 
in short-term borrowings at March 31, 1998.

     Total loans increased $32,494,110 (40.9%) to $111,925,209 at December 
31, 1997 from $79,431,099 at December 31, 1996.  Approximately $22.9 million 
of this increase occurred as a result of the acquisition of Lincoln Trail.  
The remaining $9.5 million increase in loans in 1997 was due to certain large 
borrowers being added at both the Carlinville Bank and Palmer Bank due to the 
increased lending limit of the combined organization.  Lending continued to 
increase in the first quarter of 1998, as total loans grew $3,507,956 (3.1%) 
to $115,433,165 at March 31, 1998.

     Investment securities increased $5,969,271 (10.5%) to $63,017,737 at 
December 31, 1997 from $57,048,466 at December 31, 1996.  Approximately $3.5 
million of this increase was attributable to the Lincoln Trail acquisition.  
Additionally, the available-for-sale market valuation increased a net 
$665,771 for the year ended December 31, 1997, led by the appreciation in the 
aforementioned mutual funds held by the holding company.  Investment 
securities decreased in the first quarter of 1998, declining $3,925,077 
(6.2%) to $59,092,660 at March 31, 1998, as maturities, calls, and principal 
payments received were generally rechanneled into Federal funds sold, in 
anticipation of further lending activity in future quarters.

     The capitalization of CNB remained strong in 1997 and 1998.  Total 
capital at March 31, 1998 was $21,002,911, or 10.4% of total assets on that 
date.  Total capital at December 31, 1997 was $20,433,635, or 10.4% of total 
assets at year end 1997.  At December 31, 1996, total capital was 
$18,585,779, or 12.4% of total assets at year end 1996.  Regulatory capital 
at CNB and each of the CNB Banks remained well above the required minimum 
capital levels, and CNB and its banking subsidiaries are all considered 
well-capitalized for regulatory reporting purposes.  CNB had no debt 
outstanding at December 31, 1997 or March 31, 1998.

     The following table shows the condensed average balance sheets for the 
periods reported and the percentage of each principal category of assets, 
liabilities and stockholders' equity to total assets.  Also shown is the 
average yield on each category of interest-earning assets and the average 
rate paid on each category of interest-bearing liabilities for each of the 
periods reported.

(1)  Interest includes loan fees, recorded as discussed in Note 1 to CNB's
     consolidated financial statements.
(2)  Average balances include nonaccrual loans.  The income on such loans is
     included in interest, but is recognized only upon receipt.
(3)  Interest yields are presented on a tax-equivalent basis.  Nontaxable income
     has been adjusted upward by the amount of Federal income tax that would 
     have been paid if the income had been taxable at a rate of 34%, adjusted 
     downward by the disallowance of the interest cost to carry nontaxable 
     loans and securities.

RISK MANAGEMENT

     Management's objective in structuring the balance sheet is to maximize the
return on average assets while minimizing the associated risks.  The major risks
with which CNB is concerned are credit, liquidity, interest rate and technology
risks.  The following is a discussion concerning CNB's management of these
risks. 


                                      64

     CREDIT RISK MANAGEMENT

     Managing risks CNB assumes in providing credit products to customers is 
extremely important.  Credit risk management includes defining an acceptable 
level of risk and return, establishing appropriate policies and procedures to 
govern the credit process and maintaining a thorough portfolio review 
process. Credit policies are drafted and approved at the individual bank 
level, with appropriate input from CNB management. 

     Of equal importance in the credit risk management process are the 
ongoing monitoring procedures performed as part of CNB's loan review process. 
Credit policies are examined and procedures reviewed for compliance each 
year.  Loan personnel also continually monitor loans after disbursement in an 
attempt to recognize any deterioration which may occur so that appropriate 
corrective action can be initiated on a timely basis.  These programs have 
long served CNB well and have resulted in the maintenance of quality in CNB's 
loan portfolio. 

     The addition of the loans from Palmer Bank to CNB's loan portfolio in 
1997 magnifies the importance of the credit risk management policies 
discussed above. When CNB acquired Palmer Bank on January 24, 1997, the bank 
was undercapitalized, due primarily to a significant level of problem loans 
in the Palmer Bank portfolio made prior to CNB's acquisition thereof.  Prior 
to the acquisition, Palmer Bank increased its reserve for possible loan 
losses to $1,183,535 or 5.18% of the net outstanding loans in the portfolio 
on the acquisition date.  In the ensuing months, as CNB and Palmer Bank 
management began to work through these problem loans, $968,372 of charge-offs 
were recorded at Palmer Bank, with $115,275 of recoveries received during 
1997.  The level of nonaccrual loans at Palmer Bank at December 31, 1997 was 
$545,949, compared with $1,494,585 on the acquisition date.  Additionally, 
Palmer Bank had $241,822 of loans which were delinquent 90 days or more but 
still accruing interest at December 31, 1997.  CNB management believes the 
specific reserves allocated to these nonperforming loans totaling 
approximately $180,000 at December 31, 1997 provide adequate coverage after 
considering the underlying collateral values.

     The problems experienced by Palmer Bank prior to CNB's acquisition 
thereof resulted in considerably increased regulatory scrutiny in the past 
few years. As a result of the FDIC's examination as of March 31, 1997, Palmer 
Bank's Board of Directors was required to enter into a Memorandum of 
Understanding with the FDIC requiring Palmer Bank to:  (i) adopt a written 
plan of action to reduce the level of problem loans; (ii) adopt a written 
plan of action to improve the bank's earnings level; (iii) maintain the 
reserve for possible loan losses at an adequate level; (iv) maintain Tier 1 
capital at a level equal to or exceeding 6.75% of the bank's total assets; 
(v) not declare or pay any dividends without prior regulatory approval; (vi) 
adopt a written funds management policy and appropriate interest rate risk 
measurement and monitoring procedures at the bank; and (vii) adopt a 
strategic business plan.

     It should be noted that the Memorandum of Understanding issued by the 
FDIC replaced an existing Cease and Desist Order, which had been in place 
prior to CNB's acquisition of Lincoln Trail.  While a Memorandum of 
Understanding is quite serious, it is lower on the scale of regulatory 
actions than a Cease and Desist Order.  CNB management believes the necessary 
actions have been taken toward complying with the provisions of the 
Memorandum of Understanding.  Following the most recent examination of Palmer 
Bank by the FDIC in 1998, management was informed that based upon the 
adoption by the board of directors of the Palmer Bank of a resolution, which, 
among other things, requires the Palmer Bank to be capitalized at 7% of 
assets by June 30, 1998, the Memorandum of Understanding will be terminated. 

     CNB management conducted extensive due diligence and realized the 
problems inherent in Palmer Bank when it was purchased, but continues to 
believe that, with proper management and controls, Palmer Bank will provide 
excellent market opportunities for CNB.

     Nonaccrual loans at the Carlinville Bank at December 31, 1997 were 
$319,350, down from $359,826 at December 31, 1996.  The Carlinville Bank 
incurred charge-offs of $273,549 for the year ended December 31, 1997 and 
received recoveries of $70,731.  With the exception of one commercial loan 
charge-off of $172,000 in 


                                      65
<PAGE>

1997 and $235,454 of charge-offs relating to two problem customers in 1996, 
the level of net charge-offs experienced by the Carlinville Bank have 
historically been below those experienced by its peers.

     CNB had no loans to any foreign countries at March 31, 1998 or at 
December 31, 1997 and 1996, nor did it have any concentration of loans to any 
industry, other than the agricultural industry, on these dates.  CNB has also 
refrained from financing speculative transactions such as highly leveraged 
corporate buyouts. Additionally, CNB had no other interest-bearing assets 
which were considered to be risk-element assets at March 31, 1998 or December 
31, 1997 and 1996.

     At March 31, 1998 and December 31, 1997 and 1996, CNB had loans 
outstanding to the agricultural sector of $37,037,000, $35,423,239 and 
$32,293,387, respectively which comprised 32.1%, 31.6% and 40.7%, 
respectively, of CNB's total loan portfolio.  Additionally, CNB's direct 
financing leases involve agricultural equipment which is being leased to 
local farmers.  CNB's agricultural credits are concentrated in Macoupin, 
Montgomery, Christian and Sangamon counties in central Illinois, and are 
generally fully-secured with either growing crops, farmland, livestock and/or 
machinery and equipment. Additionally, loan personnel work with their 
agricultural borrowers to monitor cash flow capabilities.

     A summary of loans by type at December 31, 1997 and 1996 is as follows:

</TABLE>

     Commercial real estate loans consist of loans secured by commercial 
property located in the four-county area served by CNB, and generally 
represent properties used by the CNB Banks' customers in their trade or 
business.

     Other commercial loans include operating, equipment, inventory and 
accounts receivable financing to small and medium size businesses in the 
four-county area.  Such loans are generally secured by the business assets of 
the entity and are personally guaranteed by the principal owners.  While 
collateral value is an important element of the underwriting process, cash 
flow analyses and debt service capacity are considered the most critical 
factors.

     Real estate construction loans represent an extension of CNB's real 
estate lending activities.  These loans are made on local construction 
projects for which permanent financing commitments are already in process.  
CNB does not finance speculative construction projects.  Loan disbursements 
are typically based on actual material and labor costs incurred, with the 
loans being collateralized by the actual construction project property.

     Residential real estate loans are predominantly made to finance 
single-family, owner-occupied properties in the four-county area.  
Loan-to-value percentage requirements for collateral are based on the lower 
of the purchase price or appraisal and are normally limited to 80%, unless 
credit enhancements are added. Appraisals are required on all owner-occupied 
residential real estate loans and private mortgage insurance is required if 
the loan-to-value percentage exceeds 85%.  These  loans generally have a 
duration of three years or less, with some 


                                      66
<PAGE>

loans repricing more frequently.  Long-term, fixed rate mortgages are not 
retained in CNB's loan portfolio, but rather are sold into the secondary 
market.

     Consumer loans consist predominantly of installment loans made for the 
purchase of new or used cars.  These loans are underwritten directly at the 
subsidiary banks and are secured by the underlying vehicles. CNB does not 
have a heavy involvement with indirect dealer lending arrangements.  CNB's 
level of credit card lending has remained fairly stable over the past few 
years with minimal losses incurred thereon.  

     CNB's loan portfolio contains certain risk elements which are identified 
in the following table, which include nonperforming loans (including loans on 
nonaccrual and loans contractually past due 90 days or more as to interest 
and principal payments):

(1)  It is the policy of CNB to periodically review its loans and to
     discontinue the accrual of interest on any loan on which full 
     collectibility of principal or interest is doubtful.  Subsequent interest
     payments received on such loans are applied to principal if there is any
     doubt as to the collectibility of such principal; otherwise, these 
     receipts are recorded as interest income.
(2)  The interest income which would have been received under the original terms
     of the nonaccrual loans in 1997 and 1996 was $80,563 and $37,000, 
     respectively. Interest income actually recorded on such loans in 1997 and
     1996 was $35,279 and $28,373, respectively.
(3)  Excludes loans accounted for on a nonaccrual basis.

     CNB had no restructured loans at March 31, 1998, or at December 31, 1997 
and 1996.  In the normal course of business, CNB's practice is to consider 
and act upon borrowers' requests for renewal of loans at their maturity.  
Evaluation of such requests includes a review of the borrower's credit 
history, the collateral securing the loan, and the purpose for such request.  
In general, loans which CNB renews at maturity require payment of accrued 
interest, a reduction in the loan balance, and/or the pledging of additional 
collateral and a potential adjustment of the interest rate to reflect changes 
in the economic conditions. 

     POTENTIAL PROBLEM LOANS

     At December 31, 1997, 28 loans with a total principal balance of 
approximately $4,704,600 were identified by management as having possible 
credit problems that raise doubts as to the ability of the borrowers to 
comply with the current repayment terms.  While these borrowers were meeting 
all of the terms of the applicable loan agreements, and adequate collateral 
coverage was generally maintained, their financial condition caused management
to believe that their loans may result in reclassification at some future 
time as nonaccrual, past due or restructured. 

     At December 31, 1997, the reserve for possible loan losses was 
$1,098,038, representing 0.98% of net outstanding loans, as compared with a 
reserve of $800,418, or 1.01%, at December 31, 1996.  The reserve as a 
percentage of nonperforming loans at December 31, 1997 and 1996 was 99.2% and 
189.2%, respectively.  The following table summarizes CNB's loan loss 
experience for the years ended December 31, 1997 and 1996.  Management 
believes its strong ongoing monitoring system has enhanced its ability to 
identify problem credits and allowed CNB to maintain an adequate reserve 
position.

     In determining an adequate balance in the reserve for possible loan 
losses, management places its emphasis as follows:  evaluation of the loan 
portfolio with regard to potential future exposure on loans to specific 
customers and industries, including a formal internal loan review function; 
reevaluation of each nonperforming loan or loan classified by supervisory 
authorities; and an overall review of the remaining portfolio in light of 
past loan loss experience. Any problems or loss exposure estimated in these 
categories was provided for in the total current period reserve. 

     Management views the reserve for possible loan losses as being available 
for all potential or presently unidentifiable loan losses which may occur in 
the future. The risk of future losses that is inherent in the loan portfolio 
is not precisely attributable to a particular loan or category of loans.  
Based on its review for adequacy, management has estimated those portions of 
the reserve that could be attributable to major categories of loans as 
detailed in the following table at December 31, 1997 and 1996:

     Allocations estimated for the loan categories do not specifically 
represent that loan charge-offs of that magnitude will be experienced in each 
of the respective categories.  The allocation does not restrict future loan 
losses attributable to a particular category of loans from being absorbed 
either by the portion of the reserve attributable to other categories or by 
an unallocated portion of the reserve.  The risk factors considered when 
determining the overall level of the reserve are the same when estimating the 
allocation by major category, as specified in the reserve summary.

     The amount of anticipated net charge-offs during 1998 is not expected to 
vary significantly from the levels reported in 1997, exclusive of the large 
charge-off identified for the Carlinville Bank and the post-acquisition 
charge-offs at Palmer Bank.  The level of anticipated charge-offs for 1998 
reflects CNB's belief that the economy in CNB's markets will remain stable in 
1998, that a majority of the current loan portfolio problems have already 
been charged-off, and sufficient collateral positions are maintained on the 
potential problem credits to preclude a significant level of additional 
charge-offs in 1998.

     Following is a summary of activity in the reserve for possible loan 
losses for the three months ended March 31, 1998:

     LIQUIDITY AND RATE SENSITIVITY MANAGEMENT

     Management of rate-sensitive earning assets and interest-bearing 
liabilities remains a key to CNB's profitability.  Management's objective is 
to produce the optimal yield and maturity mix consistent with interest rate 
expectations and projected liquidity needs.


                                      69

     Liquidity is a measurement of CNB's ability to meet the borrowing needs 
and the deposit withdrawal requirements of its customers.  The composition of 
assets and liabilities is actively managed to maintain the appropriate level 
of liquidity in the balance sheet.  Management is guided by 
regularly-reviewed policies when determining the appropriate portion of total 
assets which should be comprised of readily-marketable assets available to 
meet conditions that are reasonably expected to occur.

     Liquidity is primarily provided to CNB through earning assets, including 
Federal funds sold and maturities and principal payments in the investment 
portfolio, all funded through continued deposit growth.  Secondary sources of 
liquidity available to CNB include the sale of securities included in the 
available-for-sale category (with a carrying value of $44,142,416 and 
$41,864,482 at December 31, 1997 and March 31, 1998, respectively), and 
borrowing capabilities through the Federal Reserve Bank's seasonal borrowing 
privilege of $4.1 million maintained at the Carlinville Bank.  Additionally, 
maturing loans also provide liquidity on an ongoing basis.  Accordingly, CNB 
believes it has the liquidity necessary to meet unexpected deposit withdrawal 
requirements or increases in loan demand.

     Each of the CNB Banks controls its own asset/liability mix within the 
constraints of its individual policies and loan and deposit structure, with 
overall guidance from CNB.

     The asset/liability management process, which involves structuring the 
consolidated balance sheet to allow approximately equal amounts of assets and 
liabilities to reprice at the same time, is a dynamic process essential to 
minimize the effect of fluctuating interest rates on net interest income.  
The following table reflects CNB's consolidated  interest rate gap 
(rate-sensitive assets minus rate-sensitive liabilities) analysis as of 
December 31, 1997, individually and cumulatively, through various time 
horizons (in thousands of dollars):

     As indicated in this table, CNB operates on a short-term basis similar 
to most other financial institutions, as its liabilities, with savings and 
interest-bearing transaction accounts included, could reprice more quickly 
than its assets.  However, the process of asset/liability management in a 
financial institution is dynamic.  CNB believes its current asset/liability 
management program will allow adequate reaction time for trends in the 
marketplace as they occur, allowing maintenance of adequate net interest 
margins.  Additionally, CNB's historical analysis of customer savings and 
interest-bearing transaction accounts indicates that such deposits have 
certain "core deposit" characteristics and are not as susceptible to changes 
in the marketplace.  At March 31, 1998, the ratios of interest-sensitive 
assets to interest-sensitive liabilities did not differ significantly from 
that presented above for December 31, 1997.

     Following is a more detailed analysis of the maturity and interest rate 
sensitivity of CNB's loan portfolio at December 31, 1997:

     CNB has attempted to maintain a "laddered" maturity distribution in its 
investment portfolio.  This "laddered" approach has historically taken into 
account the probable call of securities, as well as the contractual maturity 
thereof.  Additionally, CNB maintains a significant level of public funds 
against which securities were required to be pledged.  At December 31, 1997, 
debt securities with carrying values totaling approximately $20.6 million 
were pledged to secure public funds, securities sold under repurchase 
agreements, and for other purposes, representing approximately 32.7% of CNB's 
total securities portfolio.  

     The investment portfolio is closely monitored to assure that CNB has no 
unreasonable concentration of securities in the obligations of any single 
debtor.  Other than U.S. Treasury or government agency securities, CNB 
maintains no concentration of investments in any one political subdivision 
greater than 10% of its total portfolio.

NOTE:  While yields by range of maturity are routinely provided by CNB's 
       accounting system on a tax-equivalent basis, the individual amounts of 
       adjustments are not so provided.  In total, at an assumed Federal income
       tax rate of 34%, the adjustment amounted to approximately $367,000, 
       appropriately adjusted by the disallowance of interest cost to carry 
       nontaxable securities.

     CNB's primary source of liquidity to fund growth is ultimately the 
generation of new deposits.  The following table shows the average daily 
amount of deposits and the average rate paid on each type of deposit for the 
years ended December 31, 1997 and 1996:

     CAPITAL ADEQUACY

     The Federal Reserve has established risk-based capital guidelines for 
bank holding companies, which require bank holding companies to maintain 
minimum levels of "Tier 1 Capital" and "Total Capital."  Tier 1 Capital 
consists of common and qualifying preferred stockholders' equity and minority 
interests in equity accounts of consolidated subsidiaries, less goodwill and 
50% of investments in unconsolidated subsidiaries.  Total Capital consists 
of, in addition to Tier 1 Capital, mandatory convertible debt, preferred 
stock not qualifying as Tier 1 Capital, subordinated and other qualifying 
term debt and a portion of the reserve for possible loan losses, less the 
remaining 50% of qualifying total capital.  Risk-based capital ratios are 
calculated with reference to risk-weighted assets, which include both on- and 
off-balance sheet exposures.  The minimum required ratio for qualifying Total 
Capital is 8%, of which at least 4% must consist of Tier 1 Capital. 

     In addition, Federal Reserve guidelines require bank holding companies 
to maintain a minimum ratio of Tier 1 Capital to average total assets (net of 
goodwill) of 3.0%.  The Federal Reserve guidelines state that all of these 
capital ratios constitute the minimum requirements for the most highly-rated 
banking organizations, and other banking organizations are expected to 
maintain capital at higher levels.

     As of December 31, 1997 and March 31, 1998, CNB and each of the CNB 
Banks were in compliance with the Tier 1 Capital ratio requirement and all 
other applicable regulatory capital requirements, as calculated in accordance 
with risk-based capital guidelines.  CNB's Tier 1, Total Capital and Leverage 
Ratios were 12.49%, 13.34% and 8.48%, respectively, at December 31, 1997, and 
13.38%, 14.22% and 8.46%, respectively, at March 31, 1998.

     Federal law provides the federal banking regulators with broad power to 
take prompt corrective action to resolve the problems of undercapitalized 
institutions.  The extent of the regulators' powers depends on whether the 
institution in question is "well capitalized," "adequately capitalized," 
"undercapitalized," "significantly undercapitalized" or "critically 
undercapitalized," which are defined by the regulators as follows:

</TABLE>
- --------------
  *    A critically undercapitalized institution is defined as having a
       tangible equity to total assets ratio  of 2% or less.
     
     Depending upon the capital category to which an institution is assigned, 
the regulators' corrective powers include:  requiring the submission of a 
capital restoration plan; placing limits on asset growth and restrictions on 
activities; requiring the institution to issue additional capital stock 
(including additional voting stock) or to be acquired; restricting 
transactions with affiliates; restricting the interest rate the institution 
may pay on deposits; ordering a new election of directors of the institution; 
requiring that senior executive officers or directors be dismissed; 
prohibiting the institution from accepting deposits from correspondent banks; 
requiring the institution to divest certain subsidiaries; prohibiting the 
payment of principal or interest on subordinated debt; and ultimately, 
appointing a receiver of the institution. The capital category of an 
institution also determines in part the amount of the premiums assessed 
against the institution for FDIC insurance.  At March 31, 1998 and December 
31, 1997, each of CNB's subsidiary banks were considered "well capitalized". 

     TECHNOLOGY RISK

     CNB utilizes and is dependent upon data processing hardware systems and 
banking application software to conduct its business.  The data processing 
hardware systems and banking application software include those developed and 
maintained by CNB's data processing hardware provider and purchased banking 
application software which is run on in-house computer networks.  In 1997, 
CNB initiated a review and assessment of all hardware and banking application 
software to confirm that it will function properly in the Year 2000.  CNB's 
data processing hardware provider, banking application software provider, and 
other vendors which have been contacted have indicated that their hardware 
and/or software will be Year 2000 compliant by the end of 1998, allowing CNB 
adequate time for compliance testing in 1999.  Additionally, alarms, 
elevators, heating and cooling systems and other computer-controlled 
mechanical devices on which CNB relies are being evaluated.  Those found not 
to be in compliance will be modified or replaced with compliant products.  
While there will be some incremental expenses incurred during the next 1-1/2 
years, CNB has not identified any situations at this time that will require 
material expenditures to become fully compliant with Year 2000.  During the 
next 1-1/2 years, CNB's credit risk assessment will also include a 
consideration of incremental risk that may be posed by customers' inability, 
if any, to address Year 2000 issues.

ACCOUNTING PRONOUNCEMENTS
     
     Several accounting rule changes which will or have gone into effect 
recently, as promulgated by the Financial Accounting Standards Board, will 
have an effect on CNB's financial reporting process.  These accounting rule 
changes, issued in the form of Financial Accounting Standards ("FAS"), 
include the following:
     
     -    FAS 114 and FAS 118 - Effective January 1, 1995, CNB adopted 
          Statement of Financial Accounting Standards No. 114, ACCOUNTING BY 
          CREDITORS FOR IMPAIRMENT OF A LOAN ("FAS 114"), and Statement of 
          Financial Accounting Standards No. 118, ACCOUNTING BY CREDITORS FOR 
          IMPAIRMENT OF A LOAN - INCOME RECOGNITION AND DISCLOSURES ("FAS 
          118"), which amended FAS 114.  FAS 114 (as amended by FAS 118) 
          defines the recognition criteria for impaired loans and loans for 
          which terms have been modified in troubled-debt restructurings (a 
          restructured loan). Specifically, a loan is considered impaired 
          when it is probable a creditor will be unable to collect all 
          amounts due - both principal and interest - according to the 
          contractual terms of the loan agreement.  When measuring 
          impairment, the expected future cash flows of an impaired loan is 
          required to be discounted at the loan's effective interest rate.  
          Alternatively, impairment
                                       75

<PAGE>

          could be measured by reference to an observable market price, if 
          one exists, or the fair value of the collateral for a 
          collateral-dependent loan.  Regardless of the historical 
          measurement method used, FAS 114 requires a creditor to measure 
          impairment based on the fair value of the collateral when the 
          creditor determines foreclosure is probable.  FAS 118 amends FAS 
          114 to allow a creditor to use existing methods of recognizing 
          interest income on an impaired loan, which CNB has elected to 
          continue to use. The adoption of FAS 114 and FAS 118 in 1995 
          resulted in no prospective adjustment to CNB's provision for 
          possible loan losses. 

     -    FAS 121 - CNB adopted the provisions of Statement of Financial 
          Accounting Standards No. 121, ACCOUNTING FOR THE IMPAIRMENT OF 
          LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED ("FAS 
          121") on January 1, 1996.  FAS 121 requires that long-lived assets, 
          such as bank premises and equipment, and certain identifiable 
          intangible assets, be reviewed for impairment whenever events or 
          changes in circumstances indicate that the carrying amount of an 
          asset may not be recoverable.  Recoverability of assets to be held 
          and used is measured by a comparison of the carrying amount of an 
          asset to future net cash flows expected to be generated by the 
          asset.  If such assets are considered to be impaired, the 
          impairment to be recognized is measured by the amount by which the 
          carrying amount of the assets exceeds the fair value of the assets. 
          Assets to be disposed of are reported at the lower of the carrying 
          amount or fair value less selling costs.  CNB's adoption of FAS 121 
          in 1996 had no impact on CNB's financial position, results of 
          operations, or liquidity. 

     -    FAS 125 - CNB adopted the provisions of Statement of Financial 
          Accounting Standards No. 125, TRANSFER AND SERVICING OF FINANCIAL 
          ASSETS AND EXTINGUISHMENTS OF LIABILITIES ("FAS 125"), on January 
          1, 1997.  FAS 125 provides accounting and reporting standards for 
          transfers and servicing of financial assets and extinguishments of 
          liabilities based on consistent application of a financial 
          components approach that focuses on control.  FAS 125 distinguishes 
          transfers of financial assets that are sales from transfers that 
          are secured borrowings.  Adoption of FAS 125 did not have a 
          material impact on CNB's financial position, results of operations, 
          or liquidity. 

     -    FAS 128 - In February 1997, the Financial Accounting Standards 
          Board issued Statement of Financial Accounting Standards No. 128, 
          EARNINGS PER SHARE ("FAS 128") which amends existing accounting 
          requirements and establishes standards for computing and presenting 
          earnings per share for entities with publicly-held common stock or 
          potential common stock.  FAS 128 simplifies the standards for 
          computing earnings per share, replacing the presentation of primary 
          earnings per share with basic earnings per share, which excludes 
          dilution and is computed by dividing income available to common 
          stockholders by the weighted average number of common shares 
          outstanding for the period.  FAS 128 also requires dual 
          presentation of basic and diluted earnings per share on the face of 
          the income statement for all entities with complex capital 
          structures, and requires a reconciliation of the numerator and 
          denominator of the basic earnings per share computation to the 
          numerator and denominator of the diluted earnings per share 
          computation.  Diluted earnings per share reflects the potential 
          dilution that could occur if securities or other contracts to issue 
          common stock were exercised or converted into common stock or 
          resulted in the issuance of common stock that then shares in the 
          earnings of the entity. 

          FAS 128 is effective for financial statements issued for periods 
          ending after December 15, 1997, and requires restatement of all 
          prior period earnings per share information presented.  Earlier 
          application is not permitted.  For all periods presented herein, 
          CNB did not maintain a complex capital structure as defined by FAS 
          128. 

     -    FAS 130 - In June 1997, the Financial Accounting Standards Board 
          issued Statement of Financial Accounting Standards No. 130, 
          REPORTING COMPREHENSIVE INCOME ("FAS 130").  FAS 130 establishes 
          standards for reporting and display of comprehensive income and its 
          components (revenues, expenses, gains and losses) in financial 
          statements.  FAS 130 defines comprehensive 

                                       76

<PAGE>

          income as the change in equity (net assets) of a business 
          enterprise during a period from transactions and other events and 
          circumstances from nonowner sources, including all changes in 
          equity during a period, except those resulting from investments by 
          and distributions to owners. 

          FAS 130 requires that all items that are required to be recognized 
          as comprehensive income be reported in a financial statement that 
          is displayed with the same prominence as other financial 
          statements.  FAS 130 also requires that an enterprise (a) classify 
          items of other comprehensive income by their nature in a financial 
          statement and (b) display the accumulated balance of other 
          comprehensive income separately from retained earnings and 
          additional paid in capital in the equity section of the 
          consolidated balance sheet. 

          FAS 130 is effective for fiscal years beginning after December 15, 
          1997, with reclassification of financial statements of earlier 
          periods required for comparative purposes.  CNB has implemented FAS 
          130 for all of the periods presented herein.

EFFECTS OF INFLATION
     
     Persistent high rates of inflation can have a significant effect on the 
reported financial condition and results of operations of all industries.  
However, the asset and liability structure of a bank holding company is 
substantially different from that of an industrial company, in that virtually 
all assets and liabilities of a bank holding company are monetary in nature.  
Accordingly, changes in interest rates may have a significant impact on a 
bank holding company's performance.  Interest rates do not necessarily move 
in the same direction, or in the same magnitude, as the prices of other goods 
and services.

   Inflation, however, does have an important impact on the growth of total 
assets in the banking industry, often resulting in a need to increase equity 
capital at higher than normal rates to maintain an appropriate 
equity-to-assets ratio.  One of the most important effects that inflation has 
had on the banking industry has been to reduce the proportion of earnings 
paid out in the form of dividends.

     Although it is obvious that inflation affects the growth of total 
assets, it is difficult to measure the impact precisely.  Only new assets 
acquired each year are directly affected, so a simple adjustment of asset 
totals by use of an inflation index is not meaningful.  The results of 
operations also have been affected by inflation, but again there is no simple 
way to measure the effect on the various categories of income and expense.

     Interest rates in particular are significantly affected by inflation, 
but neither the timing nor the magnitude of the changes coincide with changes 
in the consumer price index.  Additionally, changes in interest rates on some 
types of consumer deposits may be delayed.  These factors, in turn, affect 
the composition of sources of funds by reducing the growth of deposits that 
are less interest sensitive and increasing the need for funds that are more 
interest sensitive.
                                          
                        DESCRIPTION OF SHIPMAN BANCORP, INC.

MARKET AREA

     Citizens Bank's primary market area is Macoupin County, Illinois.  The 
Bank has offices in Shipman and Brighton, Illinois and has a cash-only 
dispensing ATM in Bunker Hill, which are all located in Macoupin County.  The 
primary industry of Macoupin County is agriculture.  However, Brighton is 
rapidly becoming a bedroom community of the growing communities of 
Jerseyville and Godfrey, Illinois.  Godfrey is considered part of the St. 
Louis metropolitan area.

     The town of Shipman has a population of approximately 625.  Agriculture 
is the primary industry in Macoupin County.  However, there are some other 
non-agricultural employers in Macoupin County.  The Macoupin County labor 
force is divided among manufacturing (12%), non-manufacturing (81.2%), and 
agriculture (6.8%).

     The town of Brighton has a population of approximately 3,800.  Brighton 
is a growing bedroom community of Jerseyville and Godfrey, Illinois, as 
mentioned above.  Brighton has few employers and most of its residents either 
work in Jerseyville, Godfrey or Alton, Illinois, or are engaged in 
agriculture.

LENDING ACTIVITIES

     GENERAL

     Citizens Bank provides a range of commercial and retail lending services 
to corporations, partnerships and individuals.  These credit activities 
include agricultural loans, commercial loans, residential real estate loans, 
installment loans, loan participations, leasing and lines of credit. 

     Citizens Bank has aggressively marketed its consumer, commercial and 
agricultural banking products and services to qualified lending customers in 
Macoupin County, Illinois.  The bank's senior management and lending officers 
actively solicit the business of long-standing members of the business 
community and new borrowers entering the bank's market area.  The bank's 
success can be attributed primarily to its commitment to service and its 
highly responsive relationship with its customers.

COMMERCIAL LOANS

     Citizens Bank has a small commercial loan base given the limited 
commercial lending opportunities and the agricultural-based economy of 
Macoupin County. The bank's areas of emphasis include, but are not limited 
to, loans to manufacturers, building contractors, developers and retailers.  
The bank provides a variety of business loans, including lines of credit for 
working capital purposes and term loans for the acquisition of equipment and 
other purposes.  The bank's loans are generally secured by accounts 
receivable, inventory, equipment or real estate.  The bank only makes 
unsecured loans if warranted by the overall financial condition of the 
borrower.  Citizens Bank structures its commercial and business loans on 
terms ranging from one to five years.  The majority of the bank's commercial 
and business loans have floating interest rates or mature within one year.

     The primary repayment risk for commercial loans is the failure of the 
business because of economic or financial factors.  In the vast majority of 
situations, Citizens Bank has adequately secured these loans or obtained 
personal guarantees to ensure repayment.

AGRICULTURAL LOANS

<PAGE>

     Citizens Bank's primary lending efforts have been to the agricultural 
industry.  Citizens Bank concentrates on agricultural loans because it is the 
primary industry of its trade area.  Agricultural loans currently comprise 
about 26% of the bank's loan portfolio.  Additionally, Shipman's direct 
financing leases involve agricultural equipment which is being leased to 
local farmers. The Board of Directors of the bank frequently analyzes its 
lending concentration to the agricultural industry.  Almost all of the bank's 
outstanding agricultural production, farmland and lease financing receivables 
primarily relate to farms within Macoupin County.

     Agricultural production loans, farmland loans and direct financing 
leases are provided to finance capital improvements, farm operations and 
acquisitions of livestock and machinery.  The vast majority of these loans 
are secured by crops, machinery and/or real estate.  The bank's lending 
officers work closely with its agricultural customers and assist in the 
preparation of budgets and cash flow projections for the ensuing crop year.  
The bank's lending officers closely monitor these budgets and cash flow 
projections during the year as part of the bank's risk management procedures.

CONSUMER LENDING

     Citizens Bank provides all types of consumer loans, including automobile 
and other motorized vehicles, home improvement, home equity, student loans, 
signature loans and small personal credit lines.  The bank has entered into 
an agreement with a non-affiliated third party to provide credit card 
processing. The bank has increased its cross-selling opportunities and 
improved its profitability by increasing its marketing base.

COMPETITION

     The financial services industry is very competitive.  Consequently, 
Citizens Bank improves and enhances its products and services to compete 
effectively, improve its market share, maintain flexibility and keep up with 
changing economic and social conditions.  Competition is generally based on 
price, service, convenience and location.

     The bank's target market area is competitive.  There are approximately 
nine other commercial banks that currently operate banking offices in 
Macoupin County (including the Carlinville Bank).  There are no other banks 
or financial institutions in Shipman.  However, there is one other competing 
bank with a branch location in Brighton.  There are many other financial 
institutions based in the communities surrounding Macoupin County that 
actively compete for customers within the bank's market area.  The bank also 
encounters competition from finance companies, insurance companies, mortgage 
companies, securities brokerage firms, money market funds, loan production 
offices and other providers of financial services.

     Citizens Bank competes for loans primarily through the type and quality 
of services it provides, interest rates, loan fees and location.  The bank 
believes that its long-standing presence in Shipman and its commitment to 
providing highly personal service enables it to successfully attract and 
retain individual and business customers.  Citizens Bank actively solicits 
deposit-related clients and competes for deposits by offering customers 
personal attention, professional service and competitive interest rates.

EMPLOYEES

     Citizens Bank employed 18 full-time and six part-time employees as of 
December 31, 1997.  The bank monitors its staff's development and provides 
certain training opportunities, including customer service training.  The 
bank hires new employees based on merit.  Prospective employees are evaluated 
on the basis of technical and analytical skills and customer service 
capabilities.  The bank's employees are not covered by a collective 
bargaining agreement.  The bank offers a variety of employee benefits and 
management considers its relations with employees to be very good.

BENEFIT PLANS

     EMPLOYEE 401(k) PROFIT SHARING AND STOCK OWNERSHIP PLAN

     Citizens Bank sponsors a contributory 401(k) profit sharing plan with 
provision for Citizens Bank matching contributions.  All employees meeting 
certain age and service requirements are eligible to participate in the plan. 
Citizens Bank will match an employee's contribution up to 6% of the maximum 
contribution for any one employee, with all Shipman matching contributions to 
go toward the purchase of Shipman common stock under an employee stock 
ownership plan. Matching contributions totaled $37,184 and $24,138 in 1997 
and 1996, respectively.  At December 31, 1997 and 1996, the employee stock 
ownership plan held 483.7962 shares of Shipman Common Stock.

     INCENTIVE DEFERRAL PLAN FOR DIRECTORS

     Effective January 1996, Citizens Bank adopted an Incentive Deferral Plan 
for each of its directors, allowing such directors to defer their current 
compensation earned as directors, with the bank agreeing to pay to such 
directors, or their designated beneficiaries or survivors, the total amount 
of deferred compensation plus accumulated interest at or following 
retirement. Under the Incentive Deferral Plan, interest is added to the 
accumulated deferred compensation at a periodic compound rate equal to the 
bank's return on equity for the preceding fiscal year.  The directors are 
expected to continue to render their normal service as directors of the bank 
from the date of the Plan's inception until retirement.

     The Incentive Deferral Plan stipulates that, upon disability or death 
prior to retirement, the affected director (or his/her designated 
beneficiaries or survivors) would receive a pre-determined benefit.  If the 
director dies after benefit payments commence but before receiving all such 
payments, the bank shall pay the remaining accumulated benefits to the 
director's beneficiary at the same time and in the same amounts as would have 
been paid had the director survived. Payments under the Incentive Deferral 
Plan may be made in a lump sum or periodically over a specific time period, 
with interest.

                                       81

<PAGE>

     To fund the individual agreements with each director covered under the 
Incentive Deferral Plan, the bank has purchased flexible premium universal 
life insurance policies on the lives of such directors (payable upon death to 
the bank).  Premiums for such policies are payable over the first five years 
of the plan with no further premiums or other payments due thereafter.  Each 
life insurance policy has a cash surrender value feature which allows the 
bank to receive an amount in cash upon cancellation or lapse of the policy.

     EXECUTIVE SALARY CONTINUATION PLAN

     Until March 1998, Citizens Bank maintained non-qualified Executive 
Salary Continuation Plans for four key officers providing for the payment of 
fixed annual retirement benefits to such officers, or their designated 
beneficiaries or survivors, for 15 years following their attainment of the 
normal retirement age fo 65. These plans also provided for benefits in the 
event of the executive's termination, early retirement, death or disability. 
In March 1998, two of the plans were terminated with the officers electing a 
lump sum cash distribution. The other two plans were amended to fix the 
retirement benefit based on the amounts then accrued. Subsequently, one of 
the officers, Robert A. Leisy, elected early retirement under his plan 
effective April 30, 1998.

     To fund the individual agreements with each officer under the Executive
Salary Continuation Plan, the bank has purchased flexible premium universal life
insurance policies on the lives of such officers (payable upon death to the
bank).  Each life insurance policy has a cash surrender value feature which
allows the Bank to receive an amount of cash upon cancellation or lapse of the
policy.  The cash surrender value of the policies, which is included in other
assets in the consolidated balance sheets, increases monthly, based on an
interest factor, net of mortality, administration and early termination costs
that are inherent in the contracts.

LEGAL PROCEEDINGS
     
     From time to time, Citizens Bank becomes involved as plaintiff or 
defendant in various legal actions arising in the normal course of its 
business.  While the ultimate outcome of these various legal proceedings 
cannot be predicted with certainty, it is the opinion of Shipman's management 
that there are no material pending legal proceedings to which Shipman or 
Citizens Bank is a party other than such ordinary routine litigation the 
resolution of which would not reasonably be expected to have a material 
effect on Shipman's consolidated financial position.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
     
     Citizens Bank, like many financial institutions, has followed a policy 
of granting loans to eligible officers, directors and employees for the 
financing of their businesses, personal residences and for consumer purposes. 
Citizens Bank's policy also includes the granting of unsecured personal 
loans and lines of credit based upon normal underwriting standards.  All 
loans have been made in the ordinary course of business and otherwise remain 
on substantially the same terms and conditions as those of comparable 
transactions prevailing at the time, and do not involve more than the normal 
risk of collectibility or present other unfavorable features.  The aggregate 
amount of indebtedness of Shipman's directors and officers as of December 31, 
1997, is approximately 21.5% of stockholders' equity as of such date.

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF
                               SHIPMAN BANCORP, INC.

     The following presents management's discussion and analysis of the 
consolidated financial condition and results of operations of Shipman for the 
years ended December 31, 1997 and 1996, and the three months ended March 31, 
1998 and 1997. This discussion and analysis is intended to review the 
significant factors affecting the financial condition and results of 
operations of Shipman, and provides a more comprehensive review which is not 
otherwise apparent from the consolidated financial statements alone.  This 
discussion should be read in conjunction with "SELECTED CONSOLIDATED 
FINANCIAL DATA", Shipman's consolidated financial statements and the notes 
thereto and other financial data appearing elsewhere in this Proxy 
Statement-Prospectus.

OVERVIEW

     Net income for the year ended December 31, 1997 was $291,489 or $9.06 per
share.  These results compare to net income of $136,577 or $4.29 per share for
the year ended December 31, 1996.  The most significant difference in operating
results between the two years presented was the $490,000 provision for possible
loan losses recorded in 1996, to provide for projected losses on one large
credit.  This factor is discussed more fully in the section entitled "CREDIT
RISK MANAGEMENT".

     Shipman experienced little change in its balance sheet structure between 
December 31, 1997 and 1996.  At December 31, 1997, total assets were

RESULTS OF OPERATIONS

     NET INTEREST INCOME

     Shipman's net interest income decreased by $26,999 (1.6%) to $1,688,179 
for the year ended December 31, 1997 from $1,715,178 for the year ended 
December 31, 1996.  This decrease resulted from a slight decrease in average 
earning assets from 1996 to 1997 combined with a change in the mix of earning 
assets in 1997. For the year ended December 31, 1997, average balances 
maintained in investment securities and Federal funds sold represented 27.6% 
and 4.1%, respectively, of total average earning assets. For the year ended 
December 31, 1996, average balances in investment securities and Federal 
funds sold represented 30.1% and 1.6%, respectively, of average earning 
assets.  Average loans also declined $1,002,742 (3.2%) from $31,595,797 to 
$30,593,055 for the year ended December 31, 1997, when compared with the 
corresponding period in 1996.  This shift from higher yielding loans and 
investment securities to short-term investments, maintained primarily for 
liquidity purposes, contributed to the reduction in net interest income for 
1997.

     While Shipman's net interest income decreased slightly in 1997, the net 
interest margin actually increased from 3.65% in 1996 to 3.70% in 1997.  This 
increase was due in part to a shift in the average deposit mix from the 
higher yielding category of certificates of deposit of $100,000 and over to 
the lower yielding interest-bearing transaction and savings account 
categories, as illustrated in the following table:

     Prior to 1997, for the years ended December 31, 1996 and 1995, Shipman's 
loan portfolio included approximately $1.5 million and $3.0 million, 
respectively, of loans to a national funding corporation that provided 
receivables financing on government contracts.  Shipman funded these loans 
primarily with certificates of deposit of $100,000 or more.  In late 1996, 
Shipman discontinued its funding arrangements with the national funding 
corporation, resulting in a decrease in loans and large certificates of 
deposit.

     The following table sets forth, on a tax-equivalent basis for the 
periods indicated, a summary of the changes in interest income and interest 
expense resulting from changes in volume and changes in yield/rates:

     Shipman's net interest income for the three months ended March 31, 1998 
increased $34,090 (8.2%) to $452,015 from the $417,925 recorded for the three 
months ended March 31, 1997. The percentage of average earning assets 
comprised of loans was 69.3% for the first quarter of 1998, compared with 
66.0% for the first quarter of 1997. Total loans grew $685,724 (2.2%) in the 
first quarter of 1998, primarily in the residential real estate lending area, 
as customers took advantage of the low interest rate environment to refinance 
their existing mortgages or purchase a home for the first time. Such activity 
occurred primarily at Shipman's Brighton facility. The increase in loans as a 
percentage of interest earning assets had a positive effect on Shipman's net 
interest margin in the first quarter of 1998, as the average yield on 
interest-earning assets increased 18 basis points in the first quarter of 
1998 compared with the first quarter of 1997.

     The average balances maintained for the quarter ended March 31, 1998 for 
investment securities and Federal funds sold represented 26.3% and 3.3%, 
respectively, of average interest earning assets, which was consistent with 
their percentages at December 31, 1997.

     The trend discussed above for Shipman's deposit composition continued in 
the first quarter of 1998, with a decreasing percentage of deposits 
maintained in the higher rate certificate of deposit categories. Following is 
a breakdown of Shipman's average deposit composition for the first quarters 
of 1998 and 1997:

</TABLE>

     The reduction in the percentage of average deposits comprised of higher 
rate certificates of deposit had a positive effect on Shipman's net interest 
margin in the first quarter of 1998, as the average rate paid on 
interest-bearing liabilities decreased 22 basis points when compared with the 
average rate paid in the first quarter of 1997. The combination of higher 
rates on average interest-earning assets and lower rates on interest-bearing 
liabilities resulted in a significant increase in Shipman's net interest 
margin. The net interest margin for the first quarter of 1998 was 4.12%, as 
compared with 3.70% for the first quarter of 1997.

     The following table sets forth, on a tax-equivalent basis for the 
quarterly periods indicated, a summary of the changes in interest income and

     PROVISION FOR POSSIBLE LOAN LOSSES

     Shipman recorded no provision for possible loan losses for the year 
ended December 31, 1997 following a $490,000 provision charged to operations 
for the year ended December 31, 1996.  The 1996 provision was the first such 
provision recorded for several years and was necessitated by the higher than 
normal level of net charge-offs, which totaled $591,969 in 1996, $560,931 of 
which related to one borrower.  During 1997, Shipman experienced net loan 
recoveries of $215,043, with $219,598 collected on the large charge-off in 
1996.  Shipman recorded no provision for possible loan losses in either the 
first quarter of 1998 or the first quarter of 1997.  A more detailed 
presentation of asset quality and the reserve for possible loan losses is 
included in "CREDIT RISK MANAGEMENT," below.

     NONINTEREST INCOME

     Total noninterest income for the year ended December 31, 1997 increased 
$116,674 (54.6%) to $330,475 from the $213,801 recorded in 1996.  Several 
factors have caused these increases, including the following:
     
     -    Service charge income increased as a result of the implementation 
          of a surcharge on certain ATM transactions in 1997, plus the full 
          year impact in 1997 of increases in certain deposit account-related 
          service fees which became effective in mid-year 1996.

     -    In 1996, Shipman realized losses of $35,027 on the sale of certain 
          available-for-sale securities.  No securities were sold during 1997.

                                       87

     -    In April 1996, Shipman established a mortgage banking department, 
          which originates loans for sale in the secondary market.  Income 
          from mortgage banking activities increased 105.1%, from $25,252 in 
          1996 to $51,798 in 1997.  Shipman generally retains servicing on 
          these mortgages.  This increase was due both to the increase in the 
          size of the portfolio serviced plus the impact of a full year of 
          originations and sales being included in 1997 operating results as 
          compared with only eight months in 1996.  At December 31, 1997 and 
          1996, Shipman serviced loans totaling $4,620,636 and $1,721,126, 
          respectively.

     -    Other noninterest income for 1997 included approximately $8,000 in 
          gains recognized on the sale of other real estate and approximately 
          $17,000 received from the State of Illinois in connection with a 
          road improvement project, which required Citizens Bank to give the 
          State of Illinois a small portion of land on which Shipman's 
          Brighton banking facility is located.

     Total noninterest income was up slightly for the three months ended 
March 31, 1998, increasing $10,373 (16.4%) to $73,581 from the $63,208 
recorded for the three months ended March 31, 1997. Mortgage banking revenues 
increased $3,589 (80.4%) in the first quarter of 1998 from the $4,463 earned 
in the first quarter of 1997, due to increased loan sale activity and 
servicing fees earned on a growing portfolio. Other noninterest income 
increased $6,451 (29.8%) in the first quarter of 1998 to $28,115 from the 
$21,664 earned in the first quarter of 1997, primarily due to the increase in 
the cash surrender values of life insurance policies purchased in connection 
with Shipman's Incentive Deferral Plan for Directors and Executive Salary 
Continuation Plan. See Note 9 to Shipman's consolidated financial statements 
(included elsewhere herein) for a description of these plans.

     NONINTEREST EXPENSE

     Noninterest expense increased $295,851 (23.7%) for the year ended 
December 31, 1997 to $1,544,590 from the 1996 level of $1,248,739.  Salaries 
and benefit expenses increased $68,860 (9.6%) due to a combination of merit 
increases and increased benefit expenses associated with Shipman's Executive 
Salary Continuation Plan established in March 1996.  Legal and professional 
fees increased $112,128 (164.3%) in 1997 to $180,371 from $68,243 in 1996, 
resulting primarily from legal and advisory fees incurred in connection with 
obtaining and evaluating offers from potential acquirers of Shipman.  Other 
noninterest expense during 1997 included the accrual of $47,500 to be paid in 
settlement of a pending legal claim against Citizens Bank, as described 
further in Note 10 to Shipman's consolidated financial statements, included 
elsewhere herein.

     Total noninterest expense increased $15,826 (4.4%) in the first quarter 
of 1998 to $379,175 from the $363,349 recorded in the first quarter of 1997. 
Salaries and employee benefits expenses increased $18,060 (8.2%) in the first 
quarter of 1998 as compared with the first quarter of 1997 due to the same 
combination of merit increases and increased benefit expenses associated with 
the Executive Salary Continuation Plan described in the preceding paragraph. 
Legal and professional expenses for the first quarter of 1998 increased 
$25,815 over the amount recorded in the first quarter of 1998, resulting 
primarily from professional fees incurred in connection with the Merger.

     INCOME TAXES

     Applicable income taxes increased $128,912 (240.2%) for the year ended 
December 31, 1997 to $182,575 from the $53,663 recorded in 1996.  The 
effective tax rates for 1997 and 1996 were 38.5% and 28.2%, respectively.  
The increase in tax expense for the year ended December 31, 1997 was 
attributable primarily to a lower proportion of tax-exempt income to total 
income, an increase in state income tax expense, and an increase in the level 
of alternative minimum tax paid.  The effective income tax rate for the first 
quarter of 1998 was 38.8%, which is comparable to the effective tax rate paid 
for all of 1997.

FINANCIAL CONDITION
     
     Shipman's balance sheet structure changed very little from December 31, 
1996 to December 31, 1997.  Total assets of Shipman decreased $1,178,559 
(2.4%) to $46,978,302 at December 31, 1997 from $48,156,861 at 

                                       88

<PAGE>

December 31, 1996.  Total assets at March 31, 1998 were $48,228,319, which 
represented an increase of $1,250,017 (2.7%) from the level at December 31, 
1997.  Total deposits decreased $1,537,615 (3.7%) to $40,022,348 at December 
31, 1997 from $41,559,963 at December 31, 1996.  These changes resulted 
primarily from Shipman's decision to cease funding loans to the national 
funding corporation for government contractors.  Other than real estate 
mortgage loans, which were processed by Shipman's new mortgage banking 
operation, loan demand in Shipman's immediate service areas was somewhat 
flat.  With flat loan demand, and the proceeds from maturing investments 
exceeding new loan funding requirements, Shipman was not forced to 
aggressively price its deposit products to attract growth.  Total loans 
increased only $250,200 (.8%) in 1997 to $31,133,239 at December 31, 1997 
from $30,883,039 at December 31, 1996. Total deposits at March 31, 1998 
increased $1,005,290 (2.5%) from the level at December 31, 1997, while total 
loans increased $685,724 (2.2%) during the same time period.

     Investment securities decreased $1,423,491 (10.9%) in 1997 to 
$11,667,430 at December 31, 1997 from $13,090,921 at December 31, 1996.  With 
the lack of new loan growth, proceeds from maturing investments and periodic 
principal pay-downs were invested primarily in Federal funds sold and 
interest-bearing deposits in financial institutions during 1997.  As 
indicated further below, Shipman's investment portfolio at December 31, 1997 
consisted primarily of mortgage-backed securities.  1997 activity consisted 
entirely of normal principal paydowns without subsequent reinvestment, as 
Shipman management did not want to lock into the current low rates of 
interest presently available in the bond market.  This trend has continued in 
the first quarter of 1998, as the investment portfolio declined $442,242 from 
its December 31, 1997 level to a March 31, 1998 balance of $11,225,188.

     The capitalization of Shipman remained strong throughout 1997 and into 
the first quarter of 1998.  Total capital at December 31, 1997 was 
$4,458,563, or 9.5% of total assets.  At December 31, 1996, total capital was 
$4,198,608, or 8.7% of total assets.  Total capital at March 31, 1998 was 
$4,578,797, or 9.5% of total assets.  Regulatory capital at Shipman and 
Citizens Bank remained well above the required minimum capital levels, and 
Shipman and Citizens Bank are both considered well-capitalized for regulatory 
reporting purposes.

     The following tables show the condensed average balance sheets for the 
periods reported and the percentage of each principal category of assets, 
liabilities and stockholders' equity to total assets.  Also shown is the 
average yield on each category of interest-earning assets and the average 
rate paid on each category of interest-bearing liabilities for each of the 
periods reported.

RISK MANAGEMENT
     
     Management's objective in structuring the balance sheet is to maximize 
the return on average assets while minimizing the associated risks.  The 
major risks with which Shipman is concerned are credit, liquidity, interest 
rate and technology risks.  The following is a discussion concerning 
Shipman's management of these risks.

     CREDIT RISK MANAGEMENT

     Management of the risks Shipman assumes in providing credit products to 
customers is extremely important.  Credit risk management includes defining 
an acceptable level of risk and return, establishing appropriate policies and 
procedures to govern the credit process, and maintaining a thorough portfolio 
review process. 

     Of equal importance in the credit risk management process are the 
ongoing monitoring procedures performed as part of Shipman's loan review 
process. Credit policies are examined and procedures reviewed for compliance 
each year. Loan personnel also continually monitor loans after disbursement 
in an attempt to recognize any deterioration which may occur, so that 
appropriate corrective action can be initiated on a timely basis.  These 
programs have long served Shipman well and have resulted in the maintenance 
of quality in Shipman's loan portfolio.

     Nonaccrual loans at December 31, 1997 were $207,863, up from $99,132 at 
December 31, 1996.  Shipman's nonaccrual loans at March 31, 1998 totaled 
$353,000. Shipman incurred charge-offs of $22,064 for the year ended December 
31, 1997 and received recoveries of $237,107.  For the year ended December 
31, 1996, Shipman incurred charge-offs of $606,723 and received recoveries of 
$14,754.  With the exception of one commercial loan charge-off of $560,931 in 
1996 (of which $219,598 was recovered in 1997), the level of net charge-offs 
experienced have historically been below those experienced by its peers.  For 
the first three months of 1998, Shipman had net recoveries of $12,377.

     Shipman had no loans to any foreign countries at March 31, 1998, or at 
December 31, 1997 and 1996, nor did it have any concentration of loans to any 
industry, other than the agricultural industry, on these dates.  Shipman has 
also refrained from financing speculative transactions such as highly 
leveraged corporate buyouts, and has ceased financing of the national funding 
corporation for government contractors, as was done in 1995 and 1996.  
Additionally, Shipman had no other interest-bearing assets which were 
considered to be risk-element assets at March 31, 1998, or at December 31, 
1997 and 1996.

     At December 31, 1997 and 1996, Shipman had loans outstanding to the 
agricultural sector of $8,414,978 and $9,006,787, respectively which 
comprised 27.0% and 29.2%, respectively, of Shipman's total loan portfolio.  
The corresponding amount and percentage at March 31, 1998 were $8,361,000 and 
26.3%, respectively. Additionally, Shipman's direct financing leases involve 
agricultural equipment, which is being leased to local farmers.  Shipman's 
agricultural credits are concentrated in Macoupin and Jersey counties in 
central Illinois, and are generally fully-secured with either growing crops, 
farmland, livestock and/or machinery and equipment.  Additionally, Shipman 
loan personnel work with their agricultural borrowers to monitor cash flow 
capabilities.

     A summary of loans by type at December 31, 1997 and 1996 is as follows:

     Commercial real estate loans consist of loans secured by commercial
property located in the two-county area served by Citizens Bank, and generally
represent properties used by Citizen Bank's customers in their trade or
business.

     Other commercial loans include operating, equipment, inventory and 
accounts receivable financing to small and medium size businesses in the 
two-county area. Such loans are generally secured by the business assets of 
the entity and are personally guaranteed by the principal owners.  While 
collateral value is an important element of the underwriting process, cash 
flow analyses and debt service capacity are considered the most critical 
factors.

     Real estate construction loans represent an extension of Shipman's real 
estate lending activities.  These loans are made on local construction 
projects for which permanent financing commitments are already in process.  
Shipman does not finance speculative construction projects.  Loan 
disbursements are typically based on actual material and labor costs 
incurred, with the loans being collateralized by the actual construction 
project property.

     Residential real estate loans are predominantly made to finance 
single-family, owner-occupied properties in the two-county area.  
Loan-to-value percentage requirements for collateral are based on the lower 
of the purchase price or appraisal and are normally limited to 80%.  
Appraisals are required on all owner-occupied residential real estate loans 
and private mortgage insurance is required if the loan-to-value percentage 
exceeds 85%.  These loans generally have a duration of three years or less, 
with some loans repricing more frequently.  Long-term, fixed rate mortgages 
are not retained in Shipman's loan portfolio, but rather are sold into the 
secondary market.

     Consumer loans predominantly consist of installment loans made for the 
purchase of new or used cars.  These loans are underwritten directly at 
Citizens Bank and are secured by the underlying vehicles. Shipman does not 
have a heavy involvement with indirect dealer lending arrangements.  
Shipman's level of credit card lending has remained fairly stable over the 
past few years with minimal losses incurred thereon.  

     Shipman's loan portfolio contains certain risk elements which are 
identified in the following table, which include nonperforming loans 
(including loans on nonaccrual and loans contractually past due 90 days or 
more as to interest and principal payments):

(1)  It is the policy of Shipman to periodically review its loans and to 
     discontinue the accrual of interest on any loan on which full 
     collectibility of principal or interest is doubtful.  Subsequent 
     interest payments received on such loans are applied to principal if 
     there is any doubt as to the collectibility of such principal; 
     otherwise, these receipts are recorded as interest income.

(2)  The interest income which would have been received under the original 
     terms of the nonaccrual loans for the years ended December 31, 1997 and 
     1996 was $20,790 and $9,930, respectively.  Interest income actually 
     recorded on such loans for the years ended December 31, 1997 and 1996 
     was $14,523 and $6,163, respectively.

(3)  Excludes loans accounted for on a nonaccrual basis.
     
     Shipman had no restructured loans at March 31, 1998, or at December 31, 
1997 and 1996.  In the normal course of business, Shipman's practice is to 
consider and act upon borrowers' requests for renewal of loans at their 
maturity.  Evaluation of such requests includes a review of the borrower's 
credit history, the collateral securing the loan, and the purpose for such 
request.  In general, loans which Shipman renews at maturity require payment 
of accrued interest, a reduction in the loan balance, and/or the pledging of 
additional collateral and a potential adjustment of the interest rate to 
reflect changes in the economic conditions. 

     POTENTIAL PROBLEM LOANS

     At December 31, 1997, 28 loans with a total principal balance of 
approximately $1,552,544 were identified by management as having possible 
credit problems that raise doubts as to the ability of the borrowers to 
comply with the current repayment terms.  While these borrowers were meeting 
all the terms of the applicable loan agreements, and such loans are generally 
well-collateralized, their financial condition caused management to believe 
that their loans may result in reclassification at some future time as 
nonaccrual, past due or restructured. 

     At December 31, 1997, the reserve for possible loan losses was $718,792, 
representing 2.37% of net outstanding loans, as compared with a reserve of 
$503,749, or 1.66%, at December 31, 1996.  The reserve as a percentage of 
nonperforming loans at December 31, 1997 and 1996 was 345.8% and 507.6%, 
respectively.  The following table summarizes Shipman's loan loss experience 
for the years ended December 31, 1997 and 1996.  Management believes its 
strong ongoing monitoring system has enhanced its ability to identify problem 
credits and allowed Shipman to maintain an adequate reserve position.

     In determining an adequate balance in the reserve for possible loan 
losses, management places its emphasis as follows:  evaluation of the loan 
portfolio with regard to potential future exposure on loans to specific 
customers and industries, including a formal internal loan review function; 
reevaluation of each nonperforming loan or loan classified by supervisory 
authorities; and an overall review of the remaining portfolio in light of 
past loan loss experience. Any problems or loss exposure estimated in these 
categories was provided for in the total current period reserve. 

     Management views the reserve for possible loan losses as being available 
for all potential or presently unidentifiable loan losses which may occur in 
the future. The risk of future losses that is inherent in the loan portfolio 
is not precisely attributable to a particular loan or category of loans.  
Based on its review for adequacy, management has estimated those portions of 
the reserve that could be attributable to major categories of loans as 
detailed in the following table, at December 31, 1997 and 1996:

     Allocations estimated for the loan categories do not specifically 
represent that loan charge-offs of that magnitude will be experienced in each 
of the respective categories.  The allocation does not restrict future loan 
losses attributable to a particular category of loans from being absorbed 
either by the portion of the reserve attributable to other categories or by 
an unallocated portion of the reserve.  The risk factors considered when 
determining the overall level of the reserve are the same when estimating the 
allocation by major category, as specified in the reserve summary.

     The amount of anticipated net charge-offs during the next full year is 
not expected to vary significantly from the levels reported for the years 
ended December 31, 1997 and 1996, exclusive of the $560,931 charge-off on one 
specific credit in 1996 and the related recoveries of $219,598 recorded in 
1997.  The level of anticipated charge-offs for 1998 reflects Shipman's 
belief that the economy in Shipman's markets will remain stable in 1998, and 
sufficient collateral positions are maintained on potential problem credits 
to preclude a significant level of additional charge-offs in 1998.  Shipman 
had net recoveries of $12,377 in the first quarter of 1998.  At March 31, 
1998, the reserve as a percentage of net outstanding loans and nonperforming 
loans was 2.35% and 203.7%, respectively.

     LIQUIDITY AND RATE SENSITIVITY MANAGEMENT

     Management of rate-sensitive earning assets and interest-bearing 
liabilities remains a key to Shipman's profitability.  Management's objective 
is to produce the optimal yield and maturity mix consistent with interest 
rate expectations and projected liquidity needs.

     Liquidity is a measurement of Shipman's ability to meet the borrowing 
needs and the deposit withdrawal requirements of its customers.  The 
composition of assets and liabilities is actively managed to maintain the 
appropriate level of liquidity in the balance sheet.  Management is guided by 
regularly-reviewed policies when determining the appropriate portion of total 
assets which should be comprised of readily-marketable assets available to 
meet conditions that are reasonably expected to occur.

     Liquidity is primarily provided to Shipman through earning assets, 
including Federal funds sold and maturities and principal payments in the 
investment portfolio.  Secondary sources of liquidity available to Shipman 
include the sale of securities included in the available-for-sale category 
(with a carrying value of $11,667,430 at December 31, 1997 and $11,225,188 at 
March 31, 1998), and borrowing capabilities through the Federal Home Loan 
Bank of Chicago. Additionally, maturing loans also provide liquidity on an 
ongoing basis. Accordingly,


                                       98


<PAGE>


Shipman believes it has the liquidity necessary to meet unexpected
deposit withdrawal requirements or increases in loan demand.

     The asset/liability management process, which involves structuring the 
balance sheet to allow approximately equal amounts of assets and liabilities 
to reprice at the same time, is a dynamic process essential to minimize the 
effect of fluctuating interest rates on net interest income.  The following 
table reflects Shipman's interest rate gap (rate-sensitive assets minus 
rate-sensitive liabilities) analysis as of December 31, 1997, individually 
and cumulatively, through various time horizons:

As indicated in this table, Shipman operates on a short-term basis similar to 
most other financial institutions, as its liabilities, with savings and 
interest-bearing transaction accounts included, could reprice more quickly 
than its assets.  However, the process of asset/liability management in a 
financial institution is dynamic.  Shipman believes its current 
asset/liability management program will allow adequate reaction time for 
trends in the marketplace as they occur, allowing maintenance of adequate net 
interest margins.  Additionally, Shipman's historical analysis of customer 
savings and interest-bearing transaction accounts indicates that such 
deposits have certain "core deposit" characteristics and are not as 
susceptible to changes in the marketplace. At March 31, 1998, the ratios of 
interest-sensitive assets to interest-sensitive liabilities did not differ 
significantly from that presented above at December 31, 1997.

     Following is a more detailed analysis of the maturity and interest rate 
sensitivity of Shipman's loan portfolio at December 31, 1997:

     CAPITAL ADEQUACY

     The Federal Reserve has established risk-based capital guidelines for 
bank holding companies, which require bank holding companies to maintain 
minimum levels of "Tier 1 Capital" and "Total Capital."  Tier 1 Capital 
consists of common and qualifying preferred stockholders' equity and minority 
interests in equity accounts of consolidated subsidiaries, less goodwill and 
50% of investments in unconsolidated subsidiaries.  Total Capital consists 
of, in addition to Tier 1 Capital, mandatory convertible debt, preferred 
stock not qualifying as Tier 1 Capital, subordinated and other qualifying 
term debt and a portion of the reserve for possible loan losses, less the 
remaining 50% of qualifying total capital.  Risk-based capital ratios are 
calculated with reference to risk-weighted assets, which include both on-and 
off-balance sheet exposures.  The minimum required ratio for qualifying Total 
Capital is 8%, of which at least 4% must consist of Tier 1 Capital.

     In addition, Federal Reserve guidelines require bank holding companies 
to maintain a minimum ratio of Tier 1 Capital to average total assets (net of 
goodwill).  The Federal Reserve guidelines state that all of these capital 
ratios constitute the minimum requirements for the most highly rated banking 
organizations, and other 


                                     101
<PAGE>


banking organizations are expected to maintain capital at higher levels.  In 
the case of a bank holding company like Shipman which has total consolidated 
assets of less than $150 million, the Federal Reserve's capital requirements 
apply on a bank-only basis.

     As of December 31, 1997, Shipman and Citizens Bank were in compliance 
with the Tier 1 Capital ratio requirement and all other applicable regulatory 
capital requirements, as calculated in accordance with risk-based capital 
guidelines. The Company's Tier 1, Total Capital and Leverage Ratios were 
14.5%, 15.8% and 9.3%, respectively, at December 31, 1997, and 14.4%, 15.7% 
and 9.8%, respectively, at March 31, 1998.

     Federal law provides the federal banking regulators with broad power to 
take prompt corrective action to resolve the problems of undercapitalized 
institutions.  The extent of the regulators' powers depends on whether the 
institution in question is "well capitalized," "adequately capitalized," 
"undercapitalized," "significantly undercapitalized" or "critically 
undercapitalized," which are defined by the regulators as follows:

Undercapitalized                  Less than 8       Less than 4    Less than 4
Significantly undercapitalized    Less than 6       Less than 3    Less than 3
Critically undercapitalized                 *                 *              *

</TABLE>

*A critically undercapitalized institution is defined as having a tangible
equity to total assets ratio of 2% or less.

     Depending upon the capital category to which an institution is assigned, 
the regulators' corrective powers include:  requiring the submission of a 
capital restoration plan; placing limits on asset growth and restrictions on 
activities; requiring the institution to issue additional capital stock 
(including additional voting stock) or to be acquired; restricting 
transactions with affiliates; restricting the interest rate the institution 
may pay on deposits; ordering a new election of directors of the institution; 
requiring that senior executive officers or directors be dismissed; 
prohibiting the institution from accepting deposits from correspondent banks; 
requiring the institution to divest certain subsidiaries; prohibiting the 
payment of principal or interest on subordinated debt; and ultimately, 
appointing a receiver of the institution. The capital category of an 
institution also determines in part the amount of the premiums assessed 
against the institution for FDIC insurance.  At March 31, 1998 and December 
31, 1997, Citizens Bank was considered "well capitalized".

     TECHNOLOGY RISK

     Shipman utilizes and is dependent upon data processing hardware systems 
and banking application software to conduct its business. The data processing 
hardware systems and banking application software include those developed and 
maintained by Shipman's data processing hardware provider and purchased 
banking application software which is run on in-house computer networks. In 
1997, Shipman initiated a review and assessment of all hardware and banking 
application software to confirm that it will function properly in the Year 
2000. Shipman's data processing hardware provider, banking application 
software provider, and other vendors which have been contacted have indicated 
that their hardware and/or software will be Year 2000 compliant by the end of 
1998, allowing Shipman adequate time for compliance testing in 1999. 
Additionally, alarms, elevators, heating and cooling systems and other 
computer-controlled mechanical devices on which Shipman relies are being 
evaluated. Those found not to be in compliance will be modified or replaced 
with compliant products. While there will be some incremental expenses 
incurred during the next 1 1/2 years, Shipman has not identified any 
situations at this time that will require material expenditures to become 
fully compliant with Year 2000. During the next 1 1/2 years, Shipman's credit 
risk assessment will also include a consideration of incremental risk that 
may be posed by customers' inability, if any, to address Year 2000 issues.

ACCOUNTING PRONOUNCEMENTS

     Several accounting rule changes which will or have gone into effect 
recently, as promulgated by the Financial Accounting Standards Board, will 
have an effect on Shipman's financial reporting process.  These accounting 
rule changes, issued in the form of Financial Accounting Standards (FAS) 
include the following:

     -  FAS 121 - Shipman adopted the provisions of Statement of Financial 
        Accounting Standards No. 121, ACCOUNTING FOR THE IMPAIRMENT OF 
        LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF ("FAS 
        121") on January 1, 1996.  FAS 121 requires that long-lived assets, 
        such as bank premises and equipment, and certain identifiable 
        intangible assets, be reviewed for impairment whenever events or 
        changes in circumstances indicate that the carrying amount of an 
        asset may not be recoverable.  Recoverability of assets to be held 
        and used is measured by a comparison of the carrying amount of an 
        asset to future net cash flows expected to be generated by the asset. 
         If such assets are considered to be impaired, the impairment to be 
        recognized is measured by the amount by which the carrying amount of 
        the assets exceeds the fair value of the assets.  Assets to be 
        disposed of are reported at the lower of the carrying amount or fair 
        value less selling costs.  Shipman's adoption of FAS 121 in 1996 had 
        no impact on Shipman's financial position, results of operations, or 
        liquidity.

     -  FAS 125 - Shipman adopted the provisions of Statement of Financial 
        Accounting Standards No. 125, TRANSFER AND SERVICING OF FINANCIAL 
        ASSETS AND EXTINGUISHMENTS OF LIABILITIES ("FAS 125"), on January 1, 
        1997.  FAS 125 provides accounting and reporting standards for 
        transfers and servicing of financial assets and extinguishments of 
        liabilities based on consistent application of a financial components 
        approach that focuses on control.  FAS 125 distinguishes transfers of 
        financial assets that are sales from transfers that are secured 
        borrowings.  Adoption of FAS 125 did not have a material impact on 
        Shipman's financial position, results of operations, or liquidity.

     -  FAS 128 - In February 1997, the Financial Accounting Standards Board 
        issued Statement of Financial Accounting Standards No. 128, EARNINGS 
        PER SHARE ("FAS 128") which amends existing accounting requirements 
        and establishes standards for computing and presenting earnings per 
        share for entities with publicly-held common stock or potential 
        common stock.  FAS 128 simplifies the standards for computing 
        earnings per share, replacing the presentation of primary earnings 
        per share with basic earnings per share, which excludes dilution and 
        is computed by dividing income available to common stockholders by 
        the weighted average number of common shares outstanding for the 
        period.  FAS 128 also requires dual presentation of basic and diluted 
        earnings per share on the face of the income statement for all 
        entities with complex capital structures, and requires a 
        reconciliation of the numerator and denominator of the basic earnings 
        per share computation to the numerator and denominator of the diluted 
        earnings per share computation.  Diluted earnings per share reflects 
        the potential dilution that could occur if securities or other 
        contracts to issue common stock were exercised or converted into 
        common stock or resulted in the issuance of common stock that then 
        shares in the earnings of the entity.

        FAS 128 is effective for financial statements issued for periods ending
        after December 15, 1997, and requires restatement of all prior period 
        earnings per share information presented.  For all periods presented 
        herein, Shipman did not maintain a complex capital structure as 
        defined by FAS 128.

     -  FAS 130 - In June 1997, the Financial Accounting Standards Board 
        issued Statement of Financial Accounting Standards No. 130, REPORTING 
        COMPREHENSIVE INCOME ("FAS 130").  FAS 130 establishes standards for 
        reporting and display of comprehensive income and its components 
        (revenues, expenses, gains and losses) in financial statements.  FAS 
        130 defines comprehensive income as the change in equity (net assets) 
        of a business enterprise during a period from 


                                    103
<PAGE>

        transactions and other events and circumstances from nonowner sources,
        including all changes in equity during a period, except those resulting
        from investments by and distributions to owners.

        FAS 130 requires that all items that are required to be recognized as 
        comprehensive income be reported in a financial statement that is 
        displayed with the same prominence as other financial statements.  
        FAS 130 also requires that an enterprise (a) classify items of other 
        comprehensive income by their nature in a financial statement and (b) 
        display the accumulated balance of other comprehensive income 
        separately from retained earnings and additional paid in capital in 
        the equity section of the consolidated balance sheet.

        FAS 130 is effective for fiscal years beginning after December 15, 
        1997, with reclassification of financial statements of earlier 
        periods required for comparative purposes.  Shipman has implemented 
        FAS 130 for all periods presented herein.

EFFECTS OF INFLATION

     Persistent high rates of inflation can have a significant effect on the 
reported financial condition and results of operations of all industries.  
However, the asset and liability structure of a bank holding company is 
substantially different from that of an industrial company, in that virtually 
all assets and liabilities of a bank holding company are monetary in nature.  
Accordingly, changes in interest rates may have a significant impact on a 
bank holding company's performance.  Interest rates do not necessarily move 
in the same direction, or in the same magnitude, as the prices of other goods 
and services.

     Inflation, however, does have an important impact on the growth of total 
assets in the banking industry, often resulting in a need to increase equity 
capital at higher than normal rates to maintain an appropriate 
equity-to-assets ratio.  One of the most important effects that inflation has 
had on the banking industry has been to reduce the proportion of earnings 
paid out in the form of dividends.

     Although it is obvious that inflation affects the growth of total 
assets, it is difficult to measure the impact precisely.  Only new assets 
acquired each year are directly affected, so a simple adjustment of asset 
totals by use of an inflation index is not meaningful.  The results of 
operations also have been affected by inflation, but again there is no simple 
way to measure the effect on the various categories of income and expense.

     Interest rates in particular are significantly affected by inflation, 
but neither the timing nor the magnitude of the changes coincide with changes 
in the consumer price index.  Additionally, changes in interest rates on some 
types of consumer deposits may be delayed.  These factors, in turn, affect 
the composition of sources of funds by reducing the growth of deposits that 
are less interest sensitive and increasing the need for funds that are more 
interest sensitive.

                   SUPERVISION AND REGULATION OF CNB AND SHIPMAN

     AS BANK HOLDING COMPANIES, CNB AND SHIPMAN ARE SUBJECT TO REGULATION 
UNDER THE BHCA.  THE FOLLOWING DISCUSSION SETS FORTH CERTAIN OF THE MATERIAL 
ELEMENTS OF THE REGULATORY FRAMEWORK APPLICABLE TO BANK HOLDING COMPANIES AND 
THEIR SUBSIDIARIES AND PROVIDES CERTAIN SPECIFIC INFORMATION RELEVANT TO CNB 
AND SHIPMAN.  TO THE EXTENT THAT THE FOLLOWING INFORMATION DESCRIBES 
STATUTORY AND REGULATORY PROVISIONS, IT IS QUALIFIED IN ITS ENTIRETY BY 
REFERENCE TO THE APPLICABLE STATUTORY AND REGULATORY PROVISIONS.  A CHANGE IN 
APPLICABLE STATUTES, REGULATIONS OR REGULATORY POLICY MAY HAVE A MATERIAL 
EFFECT ON THE BUSINESS OF CNB AND SHIPMAN.

GENERAL

     As registered bank holding companies, CNB and Shipman are subject to the 
supervision of, and to regular inspection by, the Federal Reserve.  The 
Carlinville Bank is organized as a national bank, which is subject to 
regulation, supervision and examination by the OCC, while Palmer Bank and 
Citizens Bank are organized as Illinois state chartered banks, which are 
subject to regulation, supervision and examination by the Commissioner.  


                                     104
<PAGE>

These banks are also subject to regulation by the FDIC and other federal 
regulatory agencies. In addition to banking laws and regulations and the 
supervisory policies of the bank regulatory agencies, CNB and Shipman and 
their subsidiaries and affiliates are subject to various other laws and 
regulations and supervision and examination by other regulatory agencies, all 
of which directly or indirectly affect the operations and management of CNB 
and Shipman and their ability to pay dividends.  The following discussion 
summarizes certain aspects of those laws and regulations that affect CNB and 
Shipman.

     The activities of CNB and Shipman and those of the companies and banks 
which each controls or in which either holds more than 5% of the voting stock 
are limited to banking, managing or controlling banks, furnishing services to 
or performing services for their subsidiaries or any other activity which the 
Federal Reserve determines to be so closely related to banking or managing or 
controlling banks as to be a proper incident thereto. In making such 
determinations, the Federal Reserve is required to consider whether the 
performance of such activities by a bank holding company or its subsidiaries 
can reasonably be expected to produce benefits to the public such as greater 
convenience, increased competition or gains in efficiency that outweigh 
possible adverse effects, such as undue concentration of resources, decreased 
or unfair competition, conflicts of interest or unsound banking practices.  
Generally, bank holding companies, such as CNB and Shipman, are required to 
obtain prior approval of the Federal Reserve to engage in any new activity or 
to acquire more than 5% of any class of voting stock of any company.

     Bank holding companies are also required to obtain the prior approval of 
the Federal Reserve before acquiring more than 5% of any class of voting 
stock of any bank which is not already majority-owned by the bank holding 
company. Pursuant to the Riegle-Neal Interstate Banking and Branching 
Efficiency Act of 1994 (the "Interstate Banking and Branching Act"), bank 
holding companies became able to acquire banks in states other than their 
home state beginning September 29, 1995, without regard to the permissibility 
of such acquisitions under state law, but subject to any state requirement 
that the bank has been organized and operating for a minimum period of time, 
not to exceed five years, and the requirement that the bank holding company, 
prior to or following the proposed acquisition, controls no more than 10% of 
the total amount of deposits of insured depository institutions in the United 
States and less than 30% of such deposits in that state (or such lesser or 
greater amount set by state law).

     The Interstate Banking and Branching Act also authorizes banks to merge 
across state lines, thereby creating interstate branches.  This provision, 
which became effective June 1, 1997, allowed each state, prior to the 
effective date, the opportunity to "opt out" of this provision, thereby 
prohibiting interstate branching within that state.  Illinois, the state in 
which all the banking subsidiaries of both CNB and Shipman are located, has 
not adopted legislation to "opt out" of the interstate branching provisions.  
Furthermore, pursuant to the Interstate Banking and Branching Act, a bank is 
now able to open new branches in a state in which it does not already have 
banking operations if such state enacts a law permitting such DE NOVO 
branching.

     Proposals to change the laws and regulations governing the banking 
industry are frequently introduced in Congress, in the state legislatures and 
before the various bank regulatory agencies.  The likelihood and timing of 
any such proposals or bills being enacted and the impact they might have on 
CNB, Shipman and their subsidiaries cannot be determined at this time.

CAPITAL AND OPERATIONAL REQUIREMENTS

     The Federal Reserve, the OCC and the FDIC have issued substantially 
similar risk-based and leverage capital guidelines applicable to United 
States banking organizations.  In addition, those regulatory agencies may 
from time to time require that a banking organization maintain capital above 
the minimum levels, whether because of the nature of its operations, its 
financial condition or its actual or anticipated growth.  The Federal Reserve 
risk-based guidelines define a two-tier capital framework.  Tier 1 capital 
consists of common and qualifying preferred stockholders' equity, less 
certain intangibles and other adjustments. Tier 2 capital consists of 
subordinated and other qualifying debt, and the reserve for possible loan 
losses up to 1.25% of risk-weighted assets.  The sum of Tier 1 and Tier 2 
capital, less investments in unconsolidated subsidiaries, represents 
qualifying total capital, at least 50% of which must consist of Tier 1 
capital.  Risk-based capital ratios are 


                                      105
<PAGE>

calculated by dividing Tier 1 and total capital by risk-weighted assets.  
Risk-weighted assets are calculated by assigning assets and off-balance sheet 
exposures to one of four categories of risk weights, based primarily on 
relative credit risk.  The minimum Tier 1 risk-based capital ratio is 4% and 
the minimum total risk-based capital ratio is 8%. CNB's Tier 1 and total 
risk-based capital ratios under these guidelines at March 31, 1998, were 
13.4% and 14.2%, respectively, and Shipman's were 14.4%  and 15.7%, 
respectively.

     The leverage ratio is determined by dividing Tier 1 capital by adjusted 
average total assets.  Although the stated minimum ratio is 3%, most banking 
organizations are required to maintain ratios of at least 100 to 200 basis 
points above 3%.  CNB's and Shipman's leverage ratios at March 31, 1998 were 
8.5% and 9.8%, respectively.

     Under current Federal Reserve Capital Adequacy guidelines, bank holding 
companies with consolidated assets of less than $150 million are generally 
exempt from the calculation and analysis of risk-based and leverage ratios on 
a consolidated holding company basis.  Shipman currently qualifies for this 
exemption.

     The Federal Deposit Insurance Corporation Improvement Act of 1991 
("FDICIA"), among other things, identifies five capital categories for 
insured depository institutions (well capitalized, adequately capitalized, 
undercapitalized, significantly undercapitalized and critically 
undercapitalized) and requires the respective Federal regulatory agencies to 
implement systems for "prompt corrective action" for insured depository 
institutions that do not meet minimum capital requirements within such 
categories.  FDICIA imposes progressively more restrictive constraints on 
operations, management and capital distributions, depending on the category 
in which an institution is classified.  Failure to meet the capital 
guidelines could also subject a banking institution to capital raising 
requirements.  An "undercapitalized" bank must develop a capital restoration 
plan and its parent holding company must guarantee that bank's compliance 
with the plan.  The liability of the parent holding company under any such 
guarantee is limited to the lesser of 5% of the bank's assets at the time it 
became "undercapitalized" or the amount needed to comply with the plan.  
Furthermore, in the event of the bankruptcy of the parent holding company, 
such guarantee would take priority over the parent's general unsecured 
creditors.  In addition, FDICIA requires the various regulatory agencies to 
prescribe certain non-capital standards for safety and soundness related 
generally to operations and management, asset quality and executive 
compensation and permits regulatory action against a financial institution 
that does not meet such standards.

     The various regulatory agencies have adopted substantially similar 
regulations that define the five capital categories identified by FDICIA, 
using the total risk-based capital, Tier 1 risk-based capital and leverage 
capital ratios as the relevant capital measures.  Such regulations establish 
various degrees of corrective action to be taken when an institution is 
considered undercapitalized.  Under the regulations, a "well capitalized" 
institution must have a Tier 1 capital ratio of at least 6%, a total capital 
ratio of at least 10% and a leverage ratio of a least 5% and not be subject 
to a capital directive order.  An "adequately capitalized" institution must 
have a Tier 1 capital ratio of at least 4%, a total capital ratio of at least 
8% and a leverage ratio of at least 4%, or 3% in some cases. Under these 
guidelines, each of the banking subsidiaries of CNB and Shipman is considered 
well capitalized at March 31, 1998.

     The banking agencies have also adopted final regulations which mandate 
that regulators take into consideration concentrations of credit risk and 
risks from nontraditional activities, as well as an institution's ability to 
manage those risks, when determining the adequacy of an institution's 
capital. This evaluation will be made as a part of the institution's regular 
safety and soundness examination. Banking agencies also have adopted final 
regulations requiring regulators to consider interest rate risk (when the 
interest rate sensitivity of an institution's assets does not match the 
sensitivity of its liabilities or its off-balance sheet positions) in the 
determination of a bank's capital adequacy.

DIVIDENDS

     CNB and Shipman both derive funds for cash dividends to their respective 
stockholders from a variety of sources, including cash and temporary 
investments.  The primary source of such funds, however, is dividends 
received from their banking subsidiaries.  Each of their banking subsidiaries 
is subject to various general 


                                     106
<PAGE>

regulatory policies and requirements relating to the payment of dividends, 
including requirements to maintain capital above regulatory minimums.  The 
appropriate federal regulatory authority is authorized to determine, under 
certain circumstances relating to the financial condition of the bank or bank 
holding company, that the payment of dividends would be an unsafe or unsound 
practice and to prohibit payment thereof.

     A major portion of CNB's holding company revenues results from dividends 
paid to it by the Carlinville Bank, which is a national bank.  The prior 
approval of the OCC is required for the payment of any dividend by a national 
bank if the total of all dividends declared by the board of directors of such 
bank in any calendar year will exceed the sum of such bank's year-to-date net 
profits for such year and its retained net profits for the preceding two 
calendar years, less any required transfers to surplus.  Federal law also 
prohibits any national bank from paying dividends which would be greater than 
such bank's undivided profits after deducting statutory bad debt in excess of 
such bank's allowance for loan losses. Under Illinois law, Illinois banks, 
such as Palmer Bank and Citizens Bank, are subject to similar prohibitions.

     Under the foregoing dividend restrictions, as of December 31, 1997, the 
Carlinville Bank, without obtaining affirmative governmental approvals, had 
additional dividends available for 1997 of $36,314 to CNB without obtaining 
prior approval from the OCC.  During 1997, the CNB Banks paid $2,364,000 
million in cash dividends to OCC.

     In addition to the foregoing, the ability of CNB, Shipman and their 
respective banking subsidiaries to pay dividends may be affected by the 
various minimum capital requirements and the capital and non-capital 
standards established under FDICIA, as described above. The right of CNB, 
Shipman and their respective stockholders to participate in any distribution 
of the assets or earnings of their respective subsidiaries is further subject 
to the prior claims of creditors of the respective subsidiaries.

SOURCE OF STRENGTH POLICY

     According to Federal Reserve policy, bank holding companies are expected 
to act as a source of financial strength to each subsidiary bank and to 
commit resources to support each such subsidiary bank.  This support may be 
required at times when a bank holding company may not be able to provide such 
support. Similarly, under the cross-guarantee provisions of the Federal 
Deposit Insurance Act, in the event of a loss suffered or anticipated by the 
FDIC -- either as a result of default of a banking or thrift subsidiary of a 
bank holding company such as CNB or Shipman or the provision of FDIC 
assistance to a subsidiary in danger of default -- the other banking 
subsidiaries of such bank holding company may be assessed for the FDIC's 
loss, subject to certain exceptions.

FDIC INSURANCE ASSESSMENTS

     The banking subsidiaries of CNB and Shipman are subject to FDIC deposit 
insurance assessments.  The FDIC has adopted a risk-based premium schedule. 
Each financial institution is assigned to one of three capital groups - well 
capitalized, adequately capitalized or undercapitalized - and further 
assigned to one of three subgroups within a capital group, on the basis of 
supervisory evaluations by the institution's primary federal and, if 
applicable, state supervisors, and on the basis of other information relevant 
to the institution's financial condition and the risk posed to the applicable 
insurance fund.  The actual assessment rate applicable to a particular 
institution will, therefore, depend in part upon the risk assessment 
classification so assigned to the institution by the FDIC.

     The Financial Institutions Reform, Recovery and Enforcement Act of 1989 
("FIRREA"), adopted in August 1989 to provide for the resolution of insolvent 
savings associations, required the FDIC to establish separate deposit 
insurance funds - the Bank Insurance Fund ("BIF") for banks and the Savings 
Association Insurance Fund ("SAIF") for savings associations.  FIRREA also 
required the FDIC to set deposit insurance assessments at such levels as 
would cause BIF and SAIF to reach their "designated reserve ratios" of 1.25 
percent of the deposits insured by them within a reasonable period of time.  
Due to the low costs of resolving bank insolvencies in the last few years, 
BIF reached its designated reserve ratio in May 1995.  As a result, 
effective January 1, 1996, the FDIC eliminated deposit insurance assessments 
(except for the minimum $2,000 payment 


                                     107
<PAGE>


required by law) for banks that are well capitalized and well managed and 
reduced the deposit insurance assessments for all other banks.

     The Deposit Insurance Funds Act of 1996 (the "Funds Act"), enacted as 
part of the Omnibus Appropriations Bill on September 30, 1996, required the 
FDIC to take immediate steps to recapitalize the SAIF to the 1.25% level, and 
to change the basis on which funds are raised to make the scheduled payments 
on the Financing Corporation ("FICO") bonds issued in 1987 to replenish the 
Federal Savings and Loan Insurance Corporation.  The new legislation combined 
with regulations issued by the FDIC immediately after enactment of the Funds 
Act, provided for a special assessment in the amount of 65.7 basis points on 
SAIF-insured deposits held by depository institutions on March 31, 1995 (the 
special assessment was required by the Funds Act to recapitalize the SAIF to 
the designated reserve ratio of 1.25 percent of the deposits insured by 
SAIF). Payments of this assessment were made in November 1996.  
Institutions (which excludes the CNB Banks and Citizens Bank) that had 
deposits insured by both the BIF and SAIF ("Oakar Banks") were required to 
pay the special assessment of 80% of their "adjusted attributable deposit 
amounts" ("AADA").  In addition, for purposes of future regular deposit 
insurance assessments, the AADA on which Oakar Banks pay assessments to SAIF 
was also reduced by 20%. Commencing January 1, 1997, BIF insured institutions 
will be responsible for a portion of the annual carrying costs of the FICO 
bonds.  Such institutions will be assessed 80% of the rate applicable to 
SAIF-insured institutions until December 31, 1999.  Effective January 1, 
1997, the Funds Act also reduced ongoing SAIF deposit insurance assessment 
rates to a range from $0.064 to $0.23 (from previous rates of $0.23 to $0.31) 
per $100 of insured deposits and increased ongoing BIF deposit insurance 
assessment rates to a range from $0.00 to $0.013 per $100 of insured 
deposits.  Additionally, pursuant to the Funds Act, if the reserves in BIF at 
the end of any semiannual assessment period exceed 1.25% of insured deposits, 
the FDIC is required to refund the excess to the BIF-insured institutions.

     The Funds Act contemplates the merger of the SAIF and BAIF by 1999, 
provided the consolidation merger of Federal bank and thrift charters under 
applicable law and regulation has been achieved by that time.  Until such 
time, however, depository institutions will continue to be prohibited from 
shifting deposits from SAIF insurance coverage to BIF insurance coverage in 
an attempt to avoid the higher SAIF assessments.  The FDIC is required to 
issue regulations to guard against the shifting of deposits from SAIF to BIF.

                          DESCRIPTION OF CNB COMMON STOCK

     THE INFORMATION SUPPLIED HEREIN OUTLINES CERTAIN PROVISIONS OF THE 
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND THE BYLAWS OF CNB.  
THIS INFORMATION DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ALL 
RESPECTS BY REFERENCE TO SUCH DOCUMENTS.

     The authorized stock of CNB is divided into one class, common stock, 
$1.00 par value, of which CNB is authorized to issue 310,000 shares.  As of 
the CNB Record Date, CNB had 186,498 shares of CNB Common Stock issued and 
outstanding, 64,072 shares reserved for issuance in connection with the 
Merger, with 13,502 shares held in treasury.  Assuming the Merger is 
consummated, it is anticipated that CNB will have a minimum of 231,348 
shares, and a maximum of 250,570 shares, of CNB Common Stock issued and 
outstanding, with 13,502 shares held in treasury.

     Holders of CNB Common Stock are entitled to dividends out of funds 
legally available for that purpose when, as and if declared by the CNB Board. 
 Each holder of CNB Common Stock is entitled to one vote for each share held, 
except that in elections for directors, CNB Stockholders are entitled to vote 
on a cumulative basis.  Under this procedure, stockholders have the right to 
vote, in person or by proxy, the number of shares owned by him or her for as 
many persons as there are directors to be elected, or to cumulate said 
shares, and give one candidate as many votes as the number of directors 
multiplied by the number of his or her shares, or to distribute them on the 
same principle among as many candidates as he or she shall see fit.  In any 
case, directors are elected by a plurality of the votes represented at a 
meeting and entitled to vote thereon.

     Generally, the presence of a majority of the issued and outstanding 
shares of CNB Common Stock entitled to vote thereat is necessary for a quorum 
at a meeting of stockholders and a majority of the votes 


                                     108
<PAGE>

represented at such a meeting and entitled to vote thereon is sufficient to 
authorize action upon routine matters. Generally speaking, significant 
corporate actions (such as, business combinations and charter amendments) 
must be approved by the holders of a majority of the issued and outstanding 
shares of CNB Common Stock.  Certain corporate actions may require a 
super-majority vote.  SEE "COMPARISON OF THE RIGHTS OF CNB STOCKHOLDERS AND 
SHIPMAN STOCKHOLDERS -- DELAWARE LAW AFFECTING BUSINESS COMBINATIONS."  CNB 
Common Stock does not have any preemptive rights, conversion rights or 
redemption rights.

     In the case of any liquidation, dissolution or winding up of the affairs 
of CNB, holders of CNB Common Stock will be entitled to receive, pro rata, 
any assets distributable to CNB Stockholders in respect to the number of 
shares held by them.

     All outstanding shares of CNB Common Stock are, and shares to be issued 
pursuant to the Merger Agreement will be when issued, fully paid and 
nonassessable.  CNB acts as the transfer agent and registrar for the CNB 
Common Stock.

                    COMPARISON OF THE RIGHTS OF CNB STOCKHOLDERS
                              AND SHIPMAN STOCKHOLDERS

     THE INFORMATION SUPPLIED HEREIN OUTLINES CERTAIN PROVISIONS OF THE 
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND THE BYLAWS OF CNB, THE 
DGCL, THE ARTICLES OF INCORPORATION AND THE BYLAWS OF SHIPMAN AND THE IBCA.  
THE INFORMATION DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN ALL 
RESPECTS BY REFERENCE TO SUCH DOCUMENTS AND STATUTES.

GENERAL

     CNB is incorporated under the laws of the State of Delaware and Shipman 
is incorporated under the laws of the State of Illinois.  Shipman 
Stockholders, whose rights are governed by the IBCA, and by Shipman's 
Articles of Incorporation (the "Articles") and Bylaws (the "Shipman Bylaws") 
will, upon consummation of the Merger, become Stockholders of CNB.  Their 
rights as CNB Stockholders will then be governed by the DGCL and by CNB's 
Amended and Restated Certificate of Incorporation (the "Certificate") and 
CNB's Bylaws (the "CNB Bylaws").  Set forth below are the material 
differences between the rights of a Shipman Stockholder under the Articles, 
the Shipman Bylaws and the IBCA, on the one hand, and the rights of a CNB 
Stockholder under the Certificate, the CNB Bylaws and the DGCL, on the other 
hand.

     Each holder of CNB Common Stock and Shipman Common Stock is entitled to 
one vote for each share held, except that in all elections of directors, both 
CNB and Shipman Stockholders are entitled to vote on a cumulative basis.  
Under this procedure, stockholders have the right to vote, in person or by 
proxy, the number of shares owned by him or her for as many persons as there 
are directors to be elected, or to cumulate said shares, and give one 
candidate as many votes as the number of directors multiplied by the number 
of his or her shares, or to distribute them on the same principle among as 
many candidates as he or she shall see fit.  In each case, CNB and Shipman 
directors are elected by a plurality of the votes represented at a meeting 
and entitled to vote thereon.

     Generally speaking, significant corporate actions (such as business 
combinations and charter amendments) must be approved by the holders of a 
majority of the issued and outstanding shares of CNB Common Stock and by not 
less than two-thirds of the Shipman Common Stock, as the case may be.  Shares 
of CNB Common Stock and Shipman Common Stock do not have any preemptive 
rights, conversion rights or redemption rights.  The dividend, liquidation 
and dissolution rights pertaining to the shares of CNB Common Stock and 
Shipman Common Stock are similar.  SEE "DESCRIPTION OF CNB COMMON STOCK."


                                     109
<PAGE>

STOCKHOLDER ACTION WITHOUT A MEETING, POWER TO CALL SPECIAL MEETINGS
AND AMENDMENT OF CERTIFICATE AND BYLAWS

     The CNB Bylaws state that stockholder action may be taken without a 
meeting if a consent in writing setting forth the action so taken is signed 
by all of the stockholders entitled to vote with respect to the subject 
matter thereof. The Shipman Bylaws contain a similar provision, except that 
the written action needs to signed only by Shipman Stockholders having not 
less than the minimum number of votes that would be necessary to authorize or 
take such action at a meeting at which all shares entitled to vote thereon 
were present and voting. Although the requirement of unanimous consent for 
any written consent of CNB Stockholders makes the taking of any action by CNB 
Stockholders by written consent virtually impossible, CNB Stockholders 
holding not less than one fifth of the outstanding voting stock are entitled 
to call a special meeting of CNB Stockholders and any stockholder action may 
be taken at a meeting of stockholders.  The Shipman Bylaws contains similar 
provisions permitting Shipman Stockholders to call a special meeting of 
stockholders.

     Neither the Certificate nor the Articles contain any specific provisions 
regarding the amendment of its respective terms.  The DGCL provides, however, 
that the Certificate may be amended by the affirmative vote of the holders of 
at least a majority of the outstanding CNB Common Stock, and the IBCA 
provides that the Articles may be amended by the affirmative vote of the 
holders of not less than two thirds of the outstanding Shipman Common Stock.  
Each of the CNB Board and the Shipman Board has concurrent power with its 
respective stockholders to adopt, amend or repeal its respective bylaws.

DIRECTORS

     As provided in the Certificate, the CNB Board consists of not less than 
five, nor more than twenty five stockholders, the exact number to be fixed 
and determined from time to time by resolution of a majority of the full CNB 
Board or by resolution of the stockholders at any special meeting.  CNB 
directors are required to own CNB Common Stock with a minimum aggregate par 
value of $200 (200 shares).  Directors serve for one year terms.

     Under the Shipman Bylaws, the Shipman Board currently consists of six 
members.  The Shipman Bylaws further provide that the number of directors may 
be increased or decreased from time to time by the amendment of the bylaw 
fixing the number of directors.  Shipman directors are not required to be 
Shipman Stockholders.  Directors serve for one year terms.

INDEMNIFICATION; LIMITATION OF PERSONAL LIABILITY

     The Certificate grants CNB the power, and the CNB Bylaws requires CNB, 
to indemnify any person against all expenses, liability and loss reasonably 
incurred or suffered by any person who was or is threatened to be made a 
party to any threatened, pending or completed action, suit or proceeding, 
whether civil, criminal, administrative or investigative (other than an 
action by or in the right of the CNB) by reason of the fact that such person 
was or is a director, officer, employee or agent of CNB or is or was serving 
at the request of CNB as a director, officer, employee or agent of any other 
corporation or entity.  The Certificate requires that to be indemnified such 
person must have acted in good faith and in a manner reasonably believed to 
be not opposed to the best interests of CNB, and, with respect to any 
criminal action or proceeding, did not have reasonable cause to believe his 
or her conduct would be unlawful. The DGCL permits CNB to indemnify a person 
against expenses incurred in connection with the defense or settlement of any 
action by or in the right of CNB if such person acted in good faith and in a 
manner reasonably believed to be in or not opposed to the best interests of 
CNB.  However, if a person is judged liable to CNB, indemnification is only 
permitted to the extent the court deems proper.

     The Certificate, the CNB Bylaws and the DGCL also provide that the 
indemnification provisions are not exclusive of any other right which a 
person seeking indemnification may have or later acquire under any statute, 
provision of the Certificate, the CNB Bylaws, agreement, vote of stockholders 
or disinterested directors or otherwise.


                                     110
<PAGE>

      In addition, the Certificate, the CNB Bylaws and the DGCL provide that 
CNB may maintain insurance, at its expense, to protect itself and any 
director, officer, employee or agent of CNB or another corporation, 
partnership, joint venture, trust or other enterprise against any expense, 
liability or loss, whether CNB has the power to indemnify such person against 
such expense, liability or loss under the DGCL.

     The Shipman Bylaws contain substantially similar indemnification 
provisions as permitted by the IBCA, except that the Shipman Bylaws provide 
that such indemnification is mandatory for any person who is or was a 
director, officer, employee or agent of Shipman.

     CNB maintains insurance on behalf of its directors and officers.

     The Certificate, as permitted by the DGCL, provides that directors of 
CNB shall not be liable to CNB or its stockholders for monetary damages for 
breaches of their fiduciary duties, except to the extent that such a 
limitation of liability contravenes the DGCL.  These provisions eliminate the 
personal liability of directors of CNB in their capacity as directors (but 
not in their capacity as officers) to CNB and its stockholders for breaches 
of their fiduciary duties to the full extent permitted by the DGCL.

     The Shipman Articles do not contain any similar provision limiting the 
personal liability of Shipman's directors.

DISSENTERS' APPRAISAL RIGHTS

     Under Section 262 of the DGCL, stockholders of a corporation who dissent 
from a merger or consolidation of the corporation in the manner provided by 
the DGCL are entitled to receive payment of the fair value of their stock, as 
determined by the Delaware Court of Chancery.  Under the DGCL, stockholders 
do not have dissenters' appraisal rights with respect to any transaction 
involving the sale, lease or exchange of all or substantially all of the 
assets of the corporation.

     The holders of the Common Stock of CNB do not have dissenters' appraisal 
rights in connection with the Merger because Shipman is merging with 
Acquisition Corp.  CNB is not a participant in the Merger and, under the 
DGCL, no dissenters' appraisal rights are available.

     The IBCA provides that Shipman Stockholders have dissenters' appraisal 
rights with respect to mergers, consolidations and share exchanges in which 
Shipman is a party if stockholder authorization is required under the IBCA or 
the Articles.  Shipman Stockholders also have dissenters' appraisal rights 
with respect to a sale, lease or exchange of all or substantially all of 
Shipman's assets and amendments to its Articles if such amendments alter or 
abolish certain rights.  SEE also "THE MERGER -- DISSENTERS' APPRAISAL 
RIGHTS."

ANTI-TAKEOVER EFFECT

     Certain provisions of applicable law may be deemed to have the effect of 
discouraging or delaying attempts to gain control of CNB.  The Change in Bank 
Control Act prohibits a person or group of persons from acquiring "control" 
of a bank holding company unless the Federal Reserve has been given sixty 
days' prior written notice of such proposed acquisition and within that time 
period the Federal Reserve has not issued a notice disapproving the proposed 
acquisition or extending for up to thirty additional days the period during 
which such a disapproval may be issued, or unless the acquisition is subject 
to Federal Reserve approval under the BHCA.  An acquisition may be made prior 
to the expiration of the disapproval period if the Federal Reserve issues 
written notice of its intent not to disapprove the action.

     In addition, any person would be required to obtain the approval of the 
Federal Reserve under the BHCA before acquiring 25% (5% in the case of an 
acquiror that is a bank holding company) or more of the outstanding shares of 
CNB Common Stock, or otherwise obtaining control over CNB.  Under the BHCA, 
"control" generally means: (i) the ownership or control of 25% or more of any 
class of voting securities of the bank holding 


                                     111

company, (ii) the ability to elect a majority of the bank holding company's 
directors, or (iii) the ability otherwise to exercise a controlling influence 
over the management and policies of the bank holding company.

     In addition to the foregoing, in certain instances the ability of the 
CNB Board to issue authorized but unissued shares of CNB Common Stock may 
have an anti-takeover effect.

     The existence of the foregoing provisions could: (i) result in CNB being 
less attractive to a potential acquiror, or (ii) result in CNB Stockholders 
receiving less for their shares of CNB Common Stock than otherwise might be 
available in the event of a takeover attempt.

                                   LEGAL MATTERS

     Certain legal matters with respect to the validity of the CNB Common 
Stock offered hereby will be passed upon for CNB by Barack Ferrazzano 
Kirschbaum Perlman & Nagelberg, Chicago, Illinois, counsel to CNB.

         Notes to Interim Condensed Consolidated Financial Statements

                           March 31, 1998 and 1997

NOTE 1 - BASIS OF PRESENTATION


Carlinville National Bank Shares, Inc. ("CNB") provides a full range of 
banking services to individual and corporate customers throughout Macoupin, 
Montgomery, Christian, and Sangamon counties of central Illinois, through the 
five locations of its wholly-owned subsidiary banks, Carlinville National 
Bank and Palmer Bank (the "CNB Banks").  CNB and its banking subsidiaries are 
subject to competition from other financial and nonfinancial institutions 
providing financial products throughout the central Illinois area.  
Additionally, CNB and its banking subsidiaries are subject to the regulations 
of certain Federal and state agencies and undergo periodic examinations by 
those regulatory agencies.  CNB also maintains a nonbanking subsidiary which 
operates a tax return preparation service.  The operations of the nonbanking 
subsidiary are not material to CNB's consolidated results of operations.

The accompanying unaudited interim condensed consolidated financial 
statements as of and for the three months ended March 31, 1998 and 1997 have 
been prepared in accordance with generally accepted accounting principles for 
interim financial information and with the instructions outlined in Rule 
10-01 of Regulation S-X of the Securities Exchange Act of 1934.  Accordingly, 
they do not include all of the information and footnotes required by 
generally accepted accounting principles for complete financial statements.  
In the opinion of management, all adjustments (consisting of normal recurring 
accruals) considered necessary for a fair presentation, have been included.  
Operating results for the period ended March 31, 1998 are not necessarily 
indicative of the results that may be expected for the year ending December 
31, 1998.  For further information, refer to the consolidated financial 
statements and footnotes thereto for the year ended December 31, 1997 
included elsewhere herein.

NOTE 2 - IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 130, REPORTING COMPREHENSIVE INCOME ("FAS 
130").  FAS 130 establishes standards for reporting and display of 
comprehensive income and its components (revenues, expenses, gains and 
losses) in financial statements.  FAS 130 defines comprehensive income as the 
change in equity (net assets) of a business enterprise during a period from 
transactions and other events and circumstances from nonowner sources, 
including all changes in equity during a period, except those resulting from 
investments by and distributions to owners.

FAS 130 requires that all items that are required to be recognized as 
comprehensive income be reported in a financial statement that is displayed 
with the same prominence as other financial statements.  FAS 130 also 
requires that an enterprise (a) classify items of other comprehensive income 
by their nature in a financial statement and (b) display the accumulated 
balance of other comprehensive income separately from retained earnings and 
additional paid in capital in the equity section of the consolidated balance 
sheet.

FAS 130 is effective for fiscal years beginning after December 31, 1997, with 
reclassification of financial statements of earlier periods required for 
comparative purposes.  The accompanying interim condensed consolidated 
financial statements as of and for the three months ended March 31, 1998 and 
1997 have been prepared in accordance with FAS 130.

Earning per common share is based on the weighted average number of common 
shares outstanding during each year.


                                     F-7
<PAGE>


In February 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 128, EARNINGS PER SHARE ("FAS 128"), 
which amends existing accounting requirements and establishes standards for 
computing and presenting earnings per share for entities with publicly-held 
common stock or potential common stock.  FAS 128 simplifies the standards for 
computing earnings per share, replacing the presentation of primary earnings 
per share with basic earnings per share, which excludes dilution and is 
computed by dividing income available to common stockholders by the weighted 
average number of common shares outstanding for the period.  FAS 128 also 
requires dual presentation of basic and diluted earnings per share on the 
face of the income statement for all entities with complex capital 
structures, and requires a reconciliation of the numerator and denominator of 
the basic earnings per share computation to the numerator and denominator of 
the diluted earnings per share computation.  Diluted earnings per share 
reflects the potential dilution that could occur if securities or other 
contracts to issue common stock were exercised or converted into common stock 
or resulted in the issuance of common stock that then shares in the earnings 
of the entity.

FAS 128 is effective for financial statements issued for periods ending after 
December 15, 1997, and requires restatement of all prior period earnings per 
share information presented.  At March 31, 1998 and 1997, CNB did not 
maintain a complex capital structure as defined by FAS 128.

CNB adopted the provisions of Statement of Financial Accounting Standards No. 
125, TRANSFER AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF 
LIABILITIES ("FAS 125"), on January 1, 1997.  FAS 125 provides accounting and 
reporting standards for transfers and servicing of financial assets and 
extinguishments of liabilities based on consistent application of a financial 
components approach that focuses on control.  FAS 125 distinguishes transfers 
of financial assets that are sales from transfers that are secured 
borrowings. Adoption of FAS 125 did not have a material impact on CNB's 
financial position, results of operations, or liquidity.

In February 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 129, DISCLOSURE OF INFORMATION ABOUT 
CAPITAL STRUCTURE ("FAS 129"), which establishes standards for disclosing 
information about an entity's capital structure.  FAS 129 is effective for 
financial statements for periods ending after December 15, 1997.  Since FAS 
129 is a disclosure requirement, it will have no impact on CNB's consolidated 
financial position and results of operations.

NOTE 3 - ACQUISITIONS AND PENDING MERGERS


Effective January 24, 1997, CNB purchased 100% of the outstanding capital 
stock of Lincoln Trail Bancshares, Inc. ("Lincoln Trail"), which owned 100% 
of the outstanding common stock of Palmer Bank in Taylorville, Illinois, in 
exchange for cash of $3,045,984.  Total consolidated assets of Lincoln Trail 
at January 24, 1997 were approximately $35.4 million.  The acquisition has 
been accounted for as a purchase transaction and, accordingly, the 
consolidated operations of Lincoln Trail from January 24, 1997 forward are 
included in the consolidated results of operations of CNB.  The excess of 
cost over the fair value of net assets acquired, which amounted to 
$2,048,407, is being amortized on a straight line basis over 15 years.

On March 27, 1998, CNB entered into a definitive agreement to acquire all of 
the outstanding common stock of Shipman Bancorp, Inc. ("Shipman") and its 
wholly-owned subsidiary, Citizens State Bank in Shipman, Illinois ("Citizens 
Bank"), which had total consolidated assets of approximately $50 million at 
December 31, 1997.  The transaction involves an exchange of two shares of CNB 
common stock or cash of $190 per share for each share of Shipman common 
stock, provided that at least 70% of the Shipman common shares are exchanged 
for CNB common stock. Using the value derived from the $190 per share cash 
price for Shipman, the transaction is valued at approximately $6,100,000.  
The transaction will be accounted for as a purchase and is expected to close 
in the third quarter of 1998, pending the approval of Shipman shareholders 
and Federal and state regulatory agencies.

                            INDEPENDENT AUDITORS' REPORT


The Board of Directors
Carlinville National Bank Shares, Inc.:

We have audited the accompanying consolidated balance sheets of Carlinville 
National Bank Shares, Inc. and subsidiaries as of December 31, 1997 and 1996, 
and the related consolidated statements of income and comprehensive income, 
stockholders' equity, and cash flows for each of the years in the three-year 
period ended December 31, 1997.  These consolidated financial statements are 
the responsibility of the Company's management.  Our responsibility is to 
express an opinion on these consolidated financial statements based on our 
audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audits to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation.  We believe that our audits provide a 
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of 
Carlinville National Bank Shares, Inc. and subsidiaries as of December 31, 
1997 and 1996, and the results of their operations and their cash flows for 
each of the years in the three-year period ended December 31, 1997, in 
conformity with generally accepted accounting principles.

                     Notes to Consolidated Financial Statements

                            December 31, 1997, 1996 and 1995


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING  POLICIES

Carlinville National Bank Shares, Inc. ("CNB") provides a full range of 
banking services to individual and corporate customers throughout Macoupin, 
Montgomery, Christian and Sangamon counties of central Illinois, through the 
five locations of its wholly-owned subsidiary banks, Carlinville National 
Bank (the Carlinville Bank) and Palmer Bank (collectively referred to as the 
"CNB Banks").  CNB and its banking subsidiaries are subject to competition 
from other financial and nonfinancial institutions providing financial 
products throughout the central Illinois area.  Additionally, CNB and its 
banking subsidiaries are subject to the regulations of certain Federal and 
state agencies and undergo periodic examinations by those regulatory 
agencies.  CNB also maintains a nonbanking subsidiary which operates a tax 
return preparation service.  The operations of the nonbanking subsidiary are 
not material to the CNB's consolidated results of operations.

The accounting and reporting policies of CNB conform to generally accepted 
accounting principles within the banking industry.  In compiling the 
consolidated financial statements, management is required to make estimates 
and assumptions, including the determination of the reserve for possible loan 
losses, that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the 
consolidated financial statements, and the reported amounts of revenues and 
expenses during the reporting period.  Actual results could differ from those 
estimates.

Following is a description of the more significant of CNB's accounting 
policies:

PRINCIPLES OF CONSOLIDATION
The consolidated financial statements include the accounts of CNB and its
wholly-owned subsidiaries.  All significant intercompany accounts and
transactions have been eliminated in consolidation.

BASIS OF ACCOUNTING
CNB and its subsidiaries utilize the accrual basis of accounting for major 
items, except for certain trust and fiduciary activities which are reported 
on the cash basis.  Results of these activities on the cash basis do not 
differ materially from those which would be reported using the accrual basis.

In June 1997, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" 
("FAS 130").  FAS 130 establishes standards for reporting and display of 
comprehensive income and its components (revenues, expenses, gains and 
losses) in financial statements.  FAS 130 defines comprehensive income as the 
change in equity (net assets) of a business enterprise during a period from 
transactions and other events and circumstances from nonowner sources, 
including all changes in equity during a period, except those resulting from 
investments by and distributions to owners.

FAS 130 requires that all items that are required to be recognized as 
comprehensive income be reported in a financial statement that is displayed 
with the same prominence as other financial statements.  FAS 130 also 
requires that an enterprise (a) classify items of other comprehensive income 
by their nature in a financial statement and (b) display the accumulated 
balance of other comprehensive income separately from retained earnings and 
additional paid in capital in the equity section of the consolidated balance 
sheet.

                     Notes to Consolidated Financial Statements


FAS 130 is effective for fiscal years beginning after December 15, 1997, with 
reclassification of financial statements of earlier periods required for 
comparative purposes.  The accompanying consolidated financial statements as 
of and for the years ended December 31, 1997, 1996 and 1995 have been 
prepared in accordance with FAS 130.

CASH FLOW INFORMATION
For purposes of the consolidated statements of cash flows, cash equivalents
include due from banks and Federal funds sold.

EARNINGS PER COMMON SHARE
Earnings per common share is based on the weighted average number of common
shares outstanding during each year.

In February 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 128, "Earnings Per Share" ("FAS 128") 
which amends existing accounting requirements and establishes standards for 
computing and presenting earnings per share for entities with publicly-held 
common stock or potential common stock.  FAS 128 simplifies the standards for 
computing earnings per share, replacing the presentation of primary earnings 
per share with basic earnings per share, which excludes dilution and is 
computed by dividing income available to common stockholders by the weighted 
average number of common shares outstanding for the period.  FAS 128 also 
requires dual presentation of basic and diluted earnings per share on the 
face of the income statement for all entities with complex capital 
structures, and requires a reconciliation of the numerator and denominator of 
the basic earnings per share computation to the numerator and denominator of 
the diluted earnings per share computation.  Diluted earnings per share 
reflects the potential dilution that could occur if securities or other 
contracts to issue common stock were exercised or converted into common stock 
or resulted in the issuance of common stock that then shares in the earnings 
of the entity.

FAS 128 is effective for financial statements issued for periods ending after 
December 15, 1997, and requires restatement of all prior period earnings per 
share information presented.  At December 31, 1997, 1996 and 1995, CNB did 
not maintain a complex capital structure as defined by FAS 128.

INVESTMENTS IN DEBT AND EQUITY SECURITIES
CNB classifies its debt securities into one of three categories at the time 
of purchase:  trading, available-for-sale or held-to-maturity.  Trading 
securities are bought and held principally for the purpose of selling them in 
the near-term.  Held-to-maturity securities are those securities which CNB 
has the ability and intent to hold until maturity.  All other debt securities 
not included in trading or held-to-maturity, and all equity securities, are 
classified as available-for-sale.

Trading and available-for-sale securities are recorded at fair value. 
Held-to-maturity securities are recorded at amortized cost, adjusted for the 
amortization of premiums or accretion of discounts.  Unrealized holding gains 
and losses on trading securities (for which no securities were so designated 
at December 31, 1997 and 1996) would be included in earnings.  Unrealized 
holding gains and losses, net of the related tax effect, on 
available-for-sale securities are excluded from earnings and reported as a 
component of other comprehensive income in stockholders' equity until 
realized.  Transfers of securities between categories would be recorded at 
fair value at the date of transfer.  Unrealized holding gains and losses 
would be recognized in earnings for any transfers into the trading category.

A decline in the market value of any available-for-sale or held-to-maturity 
security below cost that is deemed other than temporary results in a charge 
to earnings and the establishment of a new cost basis for the security.

For securities in the available-for-sale and held-to-maturity categories, 
premiums and discounts are amortized or accreted over the lives of the 
respective securities, with consideration of historical and estimated 
prepayment rates, as an adjustment to yield using a method which approximates 
the interest method.  Dividend and interest income are recognized when 
earned.  Realized gains and losses from the sale of any securities classified 
as available-for-sale are included in earnings and are derived using the 
specific identification method for determining the cost of securities sold.

LOANS
Interest on commercial, real estate and certain installment loans and direct 
financing leases is credited to income based on the principal amount 
outstanding.  Interest on the remaining installment loans is credited to 
income using a method which approximates the interest method.  The 
recognition of interest income is discontinued when, in management's 
judgment, the interest will not be collectible in the normal course of 
business.  Subsequent payments received on such loans are applied to 
principal if any doubt exists as to the collectibility of such principal; 
otherwise, such receipts are recorded as interest income.  Loans are returned 
to accrual status when management believes full collectibility of principal 
and interest is expected.

Loan origination fees and related expenses are recognized when received and 
when incurred, respectively, the results of which do not differ materially 
from generally accepted accounting principles.  Initial direct processing 
fees on direct financing leases are deferred and amortized over the lives of 
the related leases, using a method which approximates the interest method.

The reserve for possible loan losses is available to absorb loan charge-offs. 
The reserve is increased by provisions charged to operations and is reduced 
by loan charge-offs less recoveries.  The provision charged to operations 
each year is that amount which management believes is sufficient to bring the 
balance of the reserve to a level adequate to absorb potential loan losses, 
based on their knowledge and evaluation of past losses, the current loan 
portfolio, and the current economic environment in which the borrowers of 
CNB's banking subsidiaries operate.

Management believes the reserve for possible loan losses is adequate to 
absorb losses in the loan portfolio.  While management uses available 
information to recognize losses on loans, future additions to the reserve may 
be necessary based on changes in economic conditions.  Additionally, various 
regulatory agencies, as an integral part of the examination process, 
periodically review the CNB Banks' reserves for possible loan losses.  Such 
agencies may require the CNB Banks to add to their respective reserves for 
possible loan losses based on their judgments and interpretations about 
information available to them at the time of their examinations.

Effective January 1, 1995, CNB adopted Statement of Financial Accounting 
Standards No. 114, "Accounting by Creditors for Impairment of a Loan" ("FAS 
114"), and Statement of Financial Accounting Standards No. 118, "Accounting 
by Creditors for Impairment of a Loan - Income Recognition and Disclosures" 
("FAS 118"), which amended FAS 114.  FAS 114 (as amended by FAS 118) defines 
the recognition criteria for impaired loans and loans for which terms have 
been modified in troubled-debt restructurings (a restructured loan). 
Specifically, a loan is considered impaired when it is probable a creditor 
will be unable to collect all amounts due, both principal and interest, 
according to the contractual terms of the loan agreement.  When measuring 
impairment, the expected future cash flows of an impaired loan are required 
to be discounted at the loan's effective interest rate.  Alternatively, 
impairment could be measured by reference to an observable market price, if 
one exists, or the fair value of the collateral for a collateral-dependent 
loan.  Regardless of the historical measurement method used, FAS 114 requires 
a creditor to measure impairment based on the fair value

                     Notes to Consolidated Financial Statements

of the collateral when the creditor determines foreclosure is probable.  FAS 
118 amends FAS 114 to allow a creditor to use existing methods of recognizing 
interest income on an impaired loan, which CNB has elected to continue to use.

The adoption of FAS 114 and FAS 118 in 1995 resulted in no prospective 
adjustment to CNB's provision for possible loan losses.

BANK PREMISES AND EQUIPMENT
Bank premises and equipment are stated at cost, less accumulated depreciation 
and amortization.  Depreciation and amortization of premises and equipment 
are computed over the expected lives of the assets, or the related lease term 
for leasehold improvements, using both straight-line and accelerated methods. 
Estimated useful lives are 15 to 39 years for premises and three to seven 
years for leasehold improvements, furniture, fixtures, and equipment. 
Expenditures for major renewals and betterments of bank premises and 
equipment are capitalized, and those for maintenance and repairs are expensed 
as incurred.

CNB adopted the provisions of Statement of Financial Accounting Standards No. 
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived 
Assets to be Disposed Of" ("FAS 121") on January 1, 1996.  FAS 121 requires 
that long-lived assets, such as bank premises and equipment, and certain 
identifiable intangible assets, be reviewed for impairment whenever events or 
changes in circumstances indicate that the carrying amount of an asset may 
not be recoverable.  Recoverability of assets to be held and used is measured 
by a comparison of the carrying amount of an asset to future net cash flows 
expected to be generated by the asset.  If such assets are considered to be 
impaired, the impairment to be recognized is measured by the amount by which 
the carrying amount of the assets exceeds the fair value of the assets. 
Assets to be disposed of are reported at the lower of the carrying amount or 
fair value less selling costs.  CNB's adoption of FAS 121 in 1996 had no 
impact on the Company's financial position, results of operations or 
liquidity.

OTHER REAL ESTATE OWNED
Other real estate owned represents property acquired through foreclosure, or 
deeded to CNB's banking subsidiaries in lieu of foreclosure, for loans on 
which the borrowers have defaulted as to payment of principal and interest. 
Properties acquired are initially recorded at the lower of CNB's cost (less 
estimated selling costs) or fair value of the property acquired, and carried 
in other assets in the consolidated balance sheets.  Valuations are 
periodically performed by management, and an allowance for losses is 
established by means of a charge to noninterest expense if the carrying value 
of a property exceeds its fair value, less estimated selling costs. 
Subsequent increases in the fair value less estimated selling costs are 
recorded through a reversal of the allowance, but not below zero.  Costs 
related to development and improvement of property are capitalized, while 
costs relating to holding the property are expensed.

INTANGIBLE ASSETS
The core deposit intangible relating to the purchase of certain assets and 
assumption of certain liabilities of a branch location in Hillsboro, Illinois 
on December 13, 1996, is being amortized into noninterest expense on an 
straight-line basis over 15 years.

The excess of CNB's consideration given in each subsidiary acquisition 
transaction over the fair value of the net assets acquired is recorded as 
goodwill, an intangible asset on the consolidated balance sheets.  This 
amount is amortized into noninterest expense on a straight-line basis over 15 
years.

                     Notes to Consolidated Financial Statements


CNB assesses the recoverability of intangible assets by determining whether 
the amortization of the intangible assets over their remaining lives can be 
recovered through undiscounted future operating cash flows of the acquired 
operations or deposits.  The amount of impairment, if any, is measured based 
on projected discounted future operating cash flows, using a discount rate 
reflecting CNB's average cost of funds.  The assessment of the recoverability 
of intangible assets will be impacted if estimated future operating cash 
flows are not achieved.

INCOME TAXES
CNB and its subsidiaries file consolidated Federal and state income tax 
returns. Applicable income taxes are computed based on reported income and 
expenses, adjusted for permanent differences between reported and taxable 
income.

CNB uses the asset and liability method of accounting for income taxes, in 
which deferred tax assets and liabilities are recognized for the estimated 
future tax consequences attributable to differences between the financial 
statement carrying amounts of existing assets and liabilities and their 
respective tax bases.  Deferred tax assets and liabilities are measured using 
enacted tax rates in effect for the year in which those temporary differences 
are expected to be recovered or settled.  The effect on deferred tax assets 
and liabilities of a change in tax rates is recognized in the period which 
includes the enactment date.

MORTGAGE BANKING OPERATIONS
In 1997, CNB established a mortgage banking department which originates 
mortgage loans for sale to the secondary market. Servicing rights are not 
retained on the loans originated and sold. Mortgage loans held for sale are 
valued at the lower of cost or market, as determined by outstanding 
commitments from investors. Gains and losses on the sale of these loans and 
the effects of market adjustments are included in noninterest income in the 
consolidated statements of income.

DIRECTORS' INCENTIVE DEFERRAL PLAN
Effective December 1997, the Carlinville Bank adopted an Incentive Deferral 
Plan for certain of its directors, allowing such directors to defer their 
current compensation earned as directors, with the Carlinville Bank agreeing 
to pay to such directors, or their designated beneficiaries or survivors, the 
total amount of deferred compensation plus accumulated interest at or 
following retirement. Under the plan, interest is added to the accumulated 
deferred compensation at a periodic compound rate equal to the Carlinville 
Bank's return on equity before such interest charges. The directors are 
expected to continue to render their normal service as directors to the 
Carlinville Bank from the date of the Incentive Deferral Plan's inception 
until retirement.

The plan stipulates that upon disability, termination, or death prior to 
retirement, the affected director (or his or her designated beneficiaries or 
survivors) would be vested in the total deferred compensation accumulated to 
that date, plus compound interest.  Payments under the plan may be made in a 
lump sum or periodically over a specified time period, with interest.

To fund the individual agreements with each director covered under the plan, 
the Carlinville Bank has purchased flexible premium universal life insurance 
policies on the lives of such directors, (payable upon death to the 
Carlinville Bank), and paid a single one-time premium at the inception of the 
policies totaling $910,000. No other payments or premiums are required of the 
Carlinville Bank.  Each life insurance policy has a cash surrender value 
feature which allows the Carlinville Bank to receive an amount in cash upon 
cancellation or lapse of the policy. The cash surrender value of the 
policies, which is included in other assets in the consolidated balance 
sheet, increases monthly, based upon an interest factor, net of mortality, 
administration and early termination costs that are inherent in the contracts.

                     Notes to Consolidated Financial Statements


The Carlinville Bank recognizes annual compensation expense equal to the sum 
of the compensation deferred under the Incentive Deferral Plan by the 
affected directors, plus interest applied to the accumulated balance of the 
deferred compensation.  An amount is included in other liabilities in the 
consolidated balance sheet equal to the sum of all deferrals and interest 
additions accumulated to date.

FINANCIAL INSTRUMENTS
For purposes of information included in Note 13 regarding disclosures about 
financial instruments, financial instruments are defined as cash, evidence of 
an ownership interest in an entity, or a contract that both:

(a)  imposes on one entity a contractual obligation to deliver cash or
     another financial instrument to a second entity or to exchange other
     financial instruments on potentially unfavorable terms with the second
     entity, and

(b)  conveys to that second entity a contractual right to receive cash or
     another financial instrument from the first entity or to exchange other
     financial instruments on potentially favorable terms with the first
     entity.

CNB adopted the provisions of Statement of Financial Accounting Standards No. 
125, "Transfer and Servicing of Financial Assets and Extinguishments of 
Liabilities" ("FAS 125"), on January 1, 1997.  FAS 125 provides accounting 
and reporting standards for transfers and servicing of financial assets and 
extinguishments of liabilities based on consistent application of a financial 
components approach that focuses on control.  FAS 125 distinguishes transfers 
of financial assets that are sales from transfers that are secured 
borrowings. Adoption of FAS 125 did not have a material impact on CNB's 
financial position, results of operations, or liquidity.

RECLASSIFICATIONS
Certain reclassifications have been made to the 1995 and 1996 consolidated 
financial statement amounts to conform to the 1997 presentation.

NOTE 2 - ACQUISITIONS AND PENDING MERGERS

Effective December 13, 1996, the Carlinville Bank entered into a purchase and
assumption agreement to acquire certain assets and assume certain liabilities
of the Hillsboro, Illinois branch location of an unaffiliated financial
institution (the "Hillsboro Branch").  The fair value of the assets acquired
and liabilities assumed in this transaction is shown below.  The net
difference between the assets acquired from and core deposit premium paid to
the unaffiliated financial institution, and the liabilities assumed, was
settled by a cash payment from the unaffiliated financial institution on
December 13, 1996.  This purchase and assumption transaction was accounted
for as a purchase and, accordingly, the consolidated financial statements
include the financial position and results of operations of the Hillsboro
Branch for the period subsequent to the acquisition date.  The assets
acquired and liabilities assumed were recorded at their fair values at the
acquisition date.  The resulting discounts and premiums are being amortized
over the expected economic lives of the related assets and liabilities.

Effective January 24, 1997, CNB purchased 100% of the outstanding capital
stock of Lincoln Trail Bancshares, Inc. ("Lincoln Trail") which owned 100% of
the outstanding common stock of the Palmer Bank in Taylorville, Illinois, in
exchange for cash of $3,045,984.  The acquisition was accounted for as a
purchase transaction and, accordingly, the consolidated operations of Lincoln
Trail from January 24, 1997 to December 31, 1997 are included in the
consolidated results of operations of CNB for the year ended December 31,
1997. The excess of cost over the fair value of net assets acquired, which
amounted to $2,048,407, is being amortized on a straight line basis over 15
years.

The fair value of the consolidated net assets acquired from Lincoln Trail at
January 24, 1997 were as follows:

On March 27, 1998, CNB entered into a definitive agreement to acquire all of
the outstanding common stock of Shipman Bancorp, Inc. ("Shipman") and its
wholly-owned subsidiary, Citizens State Bank in Shipman, Illinois ("Citizens
Bank"), which had total consolidated assets of approximately $50 million at
December 31, 1997. The transaction involves an exchange of two shares of CNB
common stock or cash of $190 per share for each share of Shipman common
stock, provided that at least 70% of the Shipman common shares are exchanged
for CNB common stock. Using the value derived from the $190 per share cash
price for Shipman, the transaction is valued at approximately $6,100,000. The
transaction will be accounted for as a purchase and is expected to close in
the third quarter of 1998, pending the approval of Shipman stockholders and
the appropriate bank regulatory agencies.

NOTE 3 - CASH AND DUE FROM BANKS

CNB's banking subsidiaries are required to maintain certain daily reserve
balances on hand in accordance with regulatory requirements.  The reserve
balances maintained in accordance with such requirements at December 31, 1997
and 1996 were approximately $244,000 and $131,000, respectively.

</TABLE>

CNB's banking subsidiaries grant commercial, industrial, residential,
agricultural and consumer loans and direct financing leases throughout
Macoupin, Montgomery, Christian and Sangamon counties in central Illinois.
With the exception of agricultural credits, CNB does not have any particular
concentration of credit in any one economic sector; however, a substantial
portion of the portfolio is concentrated in and secured by real estate in the
four-county area.  The ability of CNB's borrowers to honor their contractual
obligations is dependent in part upon the local economies and their effect on
the real estate market.

At December 31, 1997 and 1996, CNB had loans outstanding to the agricultural
sector of $35,423,239 and $32,293,387, respectively, which comprised 31.6%
and 40.7%, respectively, of CNB's total loan portfolio.  Additionally, CNB's
direct financing leases involve agricultural equipment, which is being leased
to local area farmers. CNB's agricultural credits are concentrated in the
four-county area in central Illinois and are generally fully-secured with
either growing crops, farmland, livestock and/or machinery and equipment.
Such loans are subject to the overall national effects of the agricultural
economy, as well as the local effects relating to their central Illinois
location.

The aggregate amount of loans to executive officers and directors and loans
made for the benefit of executive officers and directors was $709,657 and
$531,733 at December 31, 1997 and 1996, respectively.  Such loans were made
in the normal course of business on substantially the same terms, including
interest rates and collateral, as those prevailing at the same time for
comparable transactions with other persons, and did not involve more than the
normal risk of collectibility.  A summary of activity for loans to executive
officers and directors for the year ended December 31, 1997 is as follows:

CNB is required to provide a valuation reserve on deferred tax assets when it 
is more likely than not that some portion of the assets will not be realized. 
CNB has not established a valuation reserve at December 31, 1997 and 1996, 
due to management's belief that all criteria for recognition have been met, 
including the existence of a history of taxes paid sufficient to support the 
realization of deferred tax assets.

4.85% and 5.28%, respectively.

The Carlinville Bank participates in the Federal Reserve Bank Seasonal 
Borrowing Privilege program, in which the Federal Reserve Bank of St. Louis 
has approved a $4,100,000 line of credit facility which the Carlinville Bank 
could utilize throughout the year to assist in meeting the requirements of 
the community.  The Seasonal Borrowing Privilege program is generally 
extended to smaller institutions which experience fluctuations in deposits 
and loans and may not have access to national money markets.  A flexible 
interest rate applies on all outstanding seasonal loans and is set biweekly 
based on the moving average of the Federal funds interest rate and the 
secondary market interest rate on 90-day large certificates of deposits.  The 
Carlinville Bank has pledged approximately $5,200,000 of real estate loans as 
security on this line of credit.  The approved seasonal line of credit may be 
significantly reduced or revoked should the Carlinville Bank at any time 
become classified as undercapitalized by a Federal banking agency.  At 
December 31, 1997, the seasonal line of credit facility remained unused.

NOTE 10 - EMPLOYEE  BENEFIT PLANS

The Carlinville Bank maintains two defined contribution plans to provide 
retirement benefits to substantially all of its employees.  Under the Money 
Purchase Plan, the Carlinville Bank is required to contribute a minimum of 5% 
of eligible employee compensation.  Under the 401(k) Plan, the Carlinville 
Bank may make discretionary matching contributions to the plan, up to the 
amount of employee contributions, subject to certain limitations. 
Contributions made by the Carlinville Bank under these plans were $184,316, 
$160,115 and $147,000 for the years ended December 31, 1997, 1996 and 1995, 
respectively.

NOTE 11 - LITIGATION

During the normal course of business, various legal claims have arisen which, 
in the opinion of management, will not result in any material liability to 
CNB.

NOTE 12 - PARENT COMPANY FINANCIAL INFORMATION

Subsidiary bank dividends are the principal source of funds for the payment 
of dividends by CNB to its stockholders and for debt servicing.  CNB's 
banking subsidiaries are subject to regulations by regulatory authorities 
which require the maintenance of minimum capital requirements.  Additionally, 
as a national bank, the Carlinville Bank is limited to the earnings of the 
current year and two previous years for the payment of dividends, without 
obtaining the prior approval of the Office of the Comptroller of the 
Currency. As an Illinois state chartered bank, Palmer Bank has no regulatory 
restrictions, other than the maintenance of minimum capital standards, and 
those required under the existing Memorandum of Understanding with the 
Federal Deposit Insurance Corporation (the "FDIC") described in Note 14, as 
to the amount of dividends Palmer Bank may pay. As of December 31, 1997, 
under the existing regulatory restrictions, the Carlinville Bank had an 
additional $36,314 available for dividends in 1998.

Following are condensed balance sheets as of December 31, 1997 and 1996 and 
the related condensed schedules of income and cash flows for each of the 
years in the three-year period ended December 31, 1997 of the CNB holding

NOTE 13 - DISCLOSURES ABOUT FINANCIAL INSTRUMENTS

CNB's banking subsidiaries issue financial instruments with off-balance-sheet 
risk in the normal course of the business of meeting the financing needs of 
their customers.  These financial instruments include commitments to extend 
credit and standby letters of credit and may involve, to varying degrees, 
elements of credit risk in excess of the amounts recognized in the 
consolidated balance sheets.  The contractual amounts of those instruments 
reflect the extent of involvement CNB has in particular classes of financial 
instruments.

CNB's exposure to credit loss in the event of nonperformance by the other 
party to the financial instrument for commitments to extend credit and 
standby letters of credit is represented by the contractual amount of those 
instruments.  CNB's banking subsidiaries use the same credit policies in 
making commitments and conditional obligations as they do for financial 
instruments included on the balance sheet.  Following is a summary of CNB's 
off-balance-sheet financial instruments at December 31, 1997 and 1996:

</TABLE>

Commitments to extend credit are agreements to lend to a customer as long as 
there is no violation of any condition established in the contract.  Of the 
total commitments to extend credit at December 31, 1997, $3,292,893 
represented fixed rate loan commitments.  Commitments generally have fixed 
expiration dates or other termination clauses and may require payment of a 
fee.  Since certain of the commitments may expire without being drawn upon, 
the total commitment amounts do not necessarily represent future cash 
requirements.  CNB's banking subsidiaries evaluate each customer's 
creditworthiness on a case-by-case basis. The amount of collateral obtained, 
if deemed necessary by CNB's banking subsidiaries upon extension of credit, 
is based on management's credit evaluation of the borrower.  Collateral held 
varies, but is generally residential or income-producing commercial property 
or equipment.

Standby letters of credit are conditional commitments issued by CNB's banking 
subsidiaries to guarantee the performance of a customer to a third party. 
Those guarantees are primarily issued to support public and private borrowing 
arrangements.  The credit risk involved in issuing letters of credit is 
essentially the same as that involved in extending loan facilities to 
customers.

The following methods and assumptions were used to estimate the fair value of 
each class of financial instruments for which it is practicable to estimate 
such value:

CASH AND OTHER SHORT-TERM INSTRUMENTS

For cash and due from banks, Federal funds sold, accrued interest receivable 
(payable), and short-term borrowings, the carrying amount is a reasonable 
estimate of fair value, as such instruments are due on demand and/or reprice 
in a short time period.

INVESTMENTS IN DEBT AND EQUITY SECURITIES

Fair values are based on quoted market prices or dealer quotes.

LOANS

For certain homogeneous categories of loans, such as residential mortgages 
and other consumer loans, fair value is estimated using the quoted market 
prices for securities backed by similar loans, adjusted for differences in 
loan characteristics.  The fair value of other types of loans is estimated by 
discounting the future cash flows using the current rates at which similar 
loans would be made to borrowers with similar credit ratings and with the 
same remaining maturities.

DEPOSITS

The fair value of demand deposits, savings accounts, and interest-bearing 
transaction account deposits is the amount payable on demand at the reporting 
date.  The fair value of fixed-maturity certificates of deposit is estimated 
using the rates currently offered for deposits of similar remaining 
maturities.

LIFE INSURANCE CONTRACTS

The fair value of insurance contracts is based on quotes of cash surrender 
values provided by the carriers.

COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTERS OF CREDIT

The fair value of commitments to extend credit and standby letters of credit 
are estimated using the fees currently charged to enter into similar 
agreements, taking into account the remaining terms of the agreements, the 
likelihood of the counterparties drawing on such financial instruments, and 
the present creditworthiness of such counterparties.  The Company believes 
such commitments have been made on terms which are competitive in the markets 
in which it operates.

NOTE 14 - REGULATORY MATTERS

CNB and its banking subsidiaries are subject to various regulatory capital 
requirements administered by the Federal banking agencies.  Failure to meet 
minimum capital requirements can initiate certain mandatory, and possible 
additional discretionary, actions by regulators that, if undertaken, could 
have a direct material effect on CNB's consolidated financial statements. 
Under capital adequacy guidelines and the regulatory framework for prompt 
corrective action, CNB and its banking subsidiaries must meet specific 
capital guidelines that involve quantitative measures of CNB's assets, 
liabilities, and certain off-balance sheet items as calculated under 
regulatory accounting practices. CNB's capital amounts and classifications 
are also subject to qualitative judgments by the regulators about components, 
risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy 
require CNB and its banking subsidiaries to maintain minimum amounts and 
ratios (set forth in the table below) of total and Tier 1 capital (as defined 
in the regulations) to risk-weighted assets (as defined), and of Tier 1 
capital to average assets (as defined).  CNB management believes, as of 
December 31, 1997, that CNB and its banking subsidiaries met all capital 
adequacy requirements to which they were subject.

As of December 31, 1997, the most recent notification from applicable 
regulatory authorities categorized CNB and its banking subsidiaries as well 
capitalized under the regulatory framework for prompt corrective action.  To 
be categorized as well capitalized, CNB and its banking subsidiaries must 
maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage 
ratios as set forth in the table below.  There are no conditions or events 
since those notifications that CNB management believes have changed the 
respective categories of CNB and its banking subsidiaries.

The actual capital amounts and ratios for CNB on a consolidated basis, and 
for the Carlinville Bank and Palmer Bank on a stand-alone bank basis at 
December 31, 1997, and the amounts and ratios for CNB on a consolidated 
basis, and for the Carlinville Bank on a stand-alone bank basis at December 
31, 1996, are presented in the following table:

On May 19, 1997, the Board of Directors of Palmer Bank entered into a 
memorandum of understanding with the FDIC requiring Palmer Bank to: (a) adopt 
a written plan of action to reduce the level of problem loans at Palmer Bank; 
(b) adopt a written plan of action to improve the earnings level of Palmer 
Bank; (c) maintain the reserve for possible loan losses at an adequate level 
at Palmer Bank; (d) maintain Tier 1 capital at a level equal to or exceeding 
6.75% of Palmer Bank's total assets, and if such ratio is less than 6.75% at 
the end of any calendar quarter, Palmer Bank must increase its Tier 1 capital 
to not less than 6.75% of total assets within 60 days thereafter; (e) not 
declare or pay any dividends without the prior written consent of the 
Regional Director of the FDIC and the Commissioner of Banks and Trust 
Companies of Illinois; (f) adopt a written funds management policy and 
appropriate interest rate risk measurement and monitoring procedures at 
Palmer Bank; and (g) adopt a strategic business plan at Palmer Bank. The FDIC 
requested the Memorandum of Understanding as a result of their March 31, 1997 
examination of Palmer Bank. These matters relate to the Bank's condition 
prior to CNB's acquisition thereof.

While no absolute assurance can be given, CNB management believes the 
necessary actions have been taken toward complying with the provisions of the 
Memorandum of Understanding.  It is not presently determinable what actions, 
if any, bank regulatory authorities might take if the provisions of the 
Memorandum of Understanding are not complied with in the specific time 
periods required.

NOTE 1 - BASIS OF PRESENTATION

Shipman Bancorp, Inc. ("Shipman") provides a full range of banking services 
to individual and corporate customers throughout Macoupin and Jersey counties 
of Illinois, through the two locations of its wholly-owned subsidiary bank, 
Citizens State Bank ("Citizens Bank").  Shipman and Citizens Bank are subject 
to competition from other financial and nonfinancial institutions providing 
financial products throughout Macoupin and Jersey counties of Illinois. 
Additionally, Shipman and Citizens Bank are subject to the regulations of 
certain Federal and state agencies and undergo periodic examinations by those 
regulatory agencies.

The accompanying unaudited interim condensed consolidated financial 
statements as of and for the three months ended March 31, 1998 and 1997 have 
been prepared in accordance with generally accepted accounting principles for 
interim financial information and with the instructions outlined in Rule 
10-01 of Regulation S-X of the Securities Exchange Act of 1934.  Accordingly, 
they do not include all of the information and footnotes required by 
generally accepted accounting principles for complete financial statements.  
In the opinion of management, all adjustments (consisting of normal recurring 
accruals) considered necessary for a fair presentation, have been included.  
Operating results for the period ended March 31, 1998 are not necessarily 
indicative of the results that may be expected for the year ending December 
31, 1998.  For further information, refer to the consolidated financial 
statements and footnotes thereto for the year ended December 31, 1997 
included elsewhere herein.

NOTE 2 - IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 130, REPORTING COMPREHENSIVE INCOME ("FAS 
130").  FAS 130 establishes standards for reporting and display of 
comprehensive income and its components (revenues, expenses, gains and 
losses) in financial statements.  FAS 130 defines comprehensive income as the 
change in equity (net assets) of a business enterprise during a period from 
transactions and other events and circumstances from nonowner sources, 
including all changes in equity during a period, except those resulting from 
investments by and distributions to owners.

FAS 130 requires that all items that are required to be recognized as 
comprehensive income be reported in a financial statement that is displayed 
with the same prominence as other financial statements.  FAS 130 also 
requires that an enterprise (a) classify items of other comprehensive income 
by their nature in a financial statement and (b) display the accumulated 
balance of other comprehensive income separately from retained earnings and 
additional paid in capital in the equity section of the consolidated balance 
sheet.

FAS 130 is effective for fiscal years beginning after December 31, 1997, with 
reclassification of financial statements of earlier periods required for 
comparative purposes.  The accompanying interim condensed consolidated 
financial statements as of and for the three months ended March 31, 1998 and 
1997 have been prepared in accordance with FAS 130.

Earnings per common share is based on the weighted average number of common
shares outstanding during each year.

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, EARNINGS PER SHARE ("FAS 128"), which
amends existing accounting requirements and establishes standards for computing
and presenting earnings per share for entities with publicly-held common stock
or potential common stock.  FAS 128 simplifies the standards for computing
earnings per share, replacing the 


                                      F-41

presentation of primary earnings per share with basic earnings per share, 
which excludes dilution and is computed by dividing income available to 
common stockholders by the weighted average number of common shares 
outstanding for the period.  FAS 128 also requires dual presentation of basic 
and diluted earnings per share on the face of the income statement for all 
entities with complex capital structures, and requires a reconciliation of 
the numerator and denominator of the basic earnings per share computation to 
the numerator and denominator of the diluted earnings per share computation.  
Diluted earnings per share reflects the potential dilution that could occur 
if securities or other contracts to issue common stock were exercised or 
converted into common stock or resulted in the issuance of common stock that 
then shares in the earnings of the entity.

FAS 128 is effective for financial statements issued for periods ending after
December 15, 1997, and requires restatement of all prior period earnings per
share information presented.  At March 31, 1998 and 1997, Shipman did not
maintain a complex capital structure as defined by FAS 128.

Shipman adopted the provisions of Statement of Financial Accounting Standards
No. 125, TRANSFER AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF
LIABILITIES ("FAS 125") on January 1, 1997.  FAS 125 provides accounting and
reporting standards for transfers and servicing of financial assets and
extinguishments of liabilities based on consistent application of a financial
components approach that focuses on control.  FAS 125 distinguishes transfers of
financial assets that are sales from transfers that are secured borrowings. 
Adoption of FAS 125 did not have a material impact on Shipman's financial
position, results of operations or liquidity.

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 129, DISCLOSURE OF INFORMATION ABOUT CAPITAL
STRUCTURE ("FAS 129"), which establishes standards for disclosing information
about an entity's capital structure.  Since FAS 129 is a disclosure requirement,
it will have no impact on Shipman's consolidated financial position and results
of operations.

NOTE 3 - ACQUISITIONS AND PENDING MERGERS

On March 27, 1998, Shipman entered into a definitive merger agreement with
Carlinville National Bank Shares, Inc. ("CNB") in which each of the outstanding
shares of Shipman common stock would be exchanged for either (a) $190 of cash,
or (b) two shares of CNB common stock, provided that at least 70% of the
Shipman's common shares are exchanged for CNB stock.  The merger transaction is
subject to the approval of Shipman's shareholders and Federal and state
regulatory agencies, and is expected to close in the third quarter of 1998, at
which time Shipman will become a wholly-owned subsidiary of CNB.

                            Independent Auditors' Report


The Board of Directors
Shipman Bancorp, Inc.:

We have audited the accompanying consolidated balance sheet of Shipman Bancorp,
Inc. and subsidiary as of December 31, 1997, and the related consolidated
statements of income and comprehensive income, stockholders' equity, and cash
flows for the year then ended.  These consolidated financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audit provides a 
reasonable basis for our opinion.

In our opinion, the 1997 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Shipman
Bancorp, Inc. and subsidiary as of December 31, 1997, and the results of their
operations and their cash flows for the year then ended, in conformity with
generally accepted accounting principles.

The consolidated balance sheet of Shipman Bancorp, Inc. and subsidiary as of
December 31, 1996, and the related consolidated statements of income and
comprehensive income, stockholders' equity, and cash flows for the year then
ended were compiled by us.  A compilation is limited to presenting in the form
of financial statements information that is the representation of management. 
We have not audited or reviewed the accompanying 1996 consolidated financial
statements and accordingly, do not express an opinion or any other form of
assurance on them.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Shipman Bancorp, Inc. ("Shipman") provides a full range of banking services 
to individual and corporate customers throughout Macoupin and Jersey counties 
of Illinois, through the two locations of its wholly-owned subsidiary bank, 
Citizens State Bank ("Citizens Bank").  Shipman and Citizens Bank are subject 
to competition from other financial and nonfinancial institutions providing 
financial products throughout Macoupin and Jersey counties in Illinois. 
Additionally, Shipman and Citizens Bank are subject to the regulations of 
certain Federal and state agencies and undergo periodic examinations by those 
regulatory agencies. 

The accounting and reporting policies of Shipman conform to generally 
accepted accounting principles within the banking industry.  In compiling the 
consolidated financial statements, management is required to make estimates 
and assumptions, including the determination of the reserve for possible loan 
losses, which significantly affect the reported amounts of assets and 
liabilities, and disclosure of contingent assets and liabilities at the date 
of the consolidated financial statements, and the reported amounts of 
revenues and expenses during the reporting period.  Actual results could 
differ from those estimates. 

Following is a description of the more significant of Shipman's accounting
policies:

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Shipman and 
Citizens Bank.  All significant intercompany accounts and transactions have 
been eliminated in consolidation.

BASIS OF ACCOUNTING

Shipman and Citizens Bank utilize the accrual basis of accounting for major 
items.

In June 1997, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" 
("FAS 130").  FAS 130 establishes standards for reporting and display of 
comprehensive income and its components (revenues, expenses, gains and 
losses) in financial statements.  FAS 130 defines comprehensive income as the 
change in equity (net assets) of a business enterprise during a period, from 
transactions and other events and circumstances from nonowner sources, 
including all changes in equity during a period, except those resulting from 
investments by and distributions to owners.

FAS 130 requires that all items that are required to be recognized as 
comprehensive income be reported in a financial statement that is displayed 
with the same prominence as other financial statements.  FAS 130 also 
requires that an enterprise (a) classify items of other comprehensive income 
by their nature in a financial statement and (b) display the accumulated 
balance of other comprehensive income separately from retained earnings and 
additional paid in capital in the equity section of the consolidated balance 
sheet.

FAS 130 is effective for fiscal years beginning after December 15, 1997, with 
reclassification of financial statements for earlier periods required for 
comparative purposes.  The accompanying consolidated financial statements as 
of and for the years ended December 31, 1997 and 1996 have been prepared in 
accordance with FAS 130.

                      Notes to Consolidated Financial Statements

CASH FLOW INFORMATION

For purposes of the consolidated statements of cash flows, cash equivalents 
include due from banks and Federal funds sold.

EARNINGS PER COMMON SHARE

Earnings per common share is based on the weighted average number of common 
shares outstanding during each year.

In February 1997, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 128, "Earnings Per Share" ("FAS 128") 
which amends existing accounting requirements and establishes standards for 
computing and presenting earnings per share for entities with publicly-held 
common stock or potential common stock.  FAS 128 simplifies the standards for 
computing earnings per share, replacing the presentation of primary earnings 
per share with basic earnings per share, which excludes dilution and is 
computed by dividing income available to common stockholders by the weighted 
average number of common shares outstanding for the period.  FAS 128 also 
requires dual presentation of basic and diluted earnings per share on the 
face of the income statement for all entities with complex capital 
structures, and requires a reconciliation of the numerator and denominator of 
the basic earnings per share computation to the numerator and denominator of 
the diluted earnings per share computation.  Diluted earnings per share 
reflects the potential dilution that could occur if securities or other 
contracts to issue common stock were exercised or converted into common stock 
or resulted in the issuance of common stock that then shares in the earnings 
of the entity.

FAS 128 is effective for financial statements issued for periods ending after 
December 15, 1997, and requires restatement of all prior period earnings per 
share information presented.  At December 31, 1997 and 1996, Shipman did not 
maintain a complex capital structure as defined by FAS 128.

INVESTMENTS IN DEBT AND EQUITY SECURITIES

Shipman classifies its debt securities into one of three categories at the 
time of purchase:  trading, available-for-sale or held-to-maturity.  Trading 
securities are bought and held principally for the purpose of selling them in 
the near-term.  Held-to-maturity securities are those securities which 
Shipman has the ability and intent to hold until maturity.  All other debt 
securities not included in trading or held-to-maturity, and all equity 
securities, are classified as available-for-sale.

Trading and available-for-sale securities are recorded at fair value.  
Held-to-maturity securities (for which no securities were so designated at 
December 31, 1997 or 1996) would be recorded at amortized cost, adjusted for 
the amortization or accretion of premiums or discounts.  Unrealized holding 
gains and losses on trading securities (for which no securities were so 
designated at December 31, 1997 and 1996) would be included in earnings.  
Unrealized holding gains and losses, net of the related tax effect, on 
available-for-sale securities are excluded from earnings and reported as a 
component of other comprehensive income in stockholders' equity until 
realized.  Transfers of securities between categories would be recorded at 
fair value at the date of transfer.  Unrealized holding gains and losses 
would be recognized in earnings for transfers into the trading category.  A 
decline in the market value of any available-for-sale or held-to-maturity 
security below cost that is deemed other than temporary results in a charge 
to earnings and the establishment of a new cost basis for the security.

For securities in the available-for-sale and held-to-maturity categories, 
premiums are amortized and discounts are accreted over the lives of the 
respective securities, with consideration of historical and estimated 
prepayment rates, as an adjustment to yield using the interest method.  
Dividend and interest income are recognized when earned.  Realized gains and 
losses from the sale of any securities classified as available-for-sale are 
included in earnings and are derived using the specific identification method 
for determining the cost of securities sold.

LOANS

Interest on commercial, real estate and certain installment loans is credited to
income based on the principal amount outstanding.  Interest on the remaining
installment loans and direct financing leases is credited to income using a
method which approximates the interest method.  The recognition of interest
income is discontinued when, in management's judgment, the interest will not be
collectible in the normal course of business.  Subsequent payments received on
such loans are applied to principal if any doubt exists as to the collectibility
of such principal; otherwise, such receipts are recorded as interest income. 
Loans are returned to accrual status when management believes full
collectibility of principal and interest is expected.  Shipman considers a loan
to be impaired when it is probable Citizens Bank will be unable to collect all
amounts due, both principal and interest, according to the contractual terms of
the loan agreement.  When measuring impairment, the expected future cash flows
of an impaired loan is discounted at the loan's effective interest rate, or
alternatively, is measured by reference to an observable market price, if one
exists, or the fair value of the collateral for a collateral-dependent loan. 
However, impairment is measured based on the fair value of the collateral when
foreclosure is probable.  

Loan origination fees and related expenses are recognized when received and when
incurred, respectively, the results of which do not differ materially from
generally accepted accounting principles.  Initial direct processing fees on
direct financing leases are deferred and amortized over the lives of the related
leases, using a method which approximates the interest method.

The reserve for possible loan losses is available to absorb loan charge-offs. 
The reserve is increased by provisions charged to operations and is reduced by
loan charge-offs less recoveries.  The provision charged to operations each year
is that amount which management believes is sufficient to bring the balance of
the reserve to a level adequate to absorb potential loan losses, based on their
knowledge and evaluation of past losses, the current loan portfolio, and the
current economic environment in which the borrowers of Citizens Bank operate.

Management believes the reserve for possible loan losses is adequate to absorb
losses in the loan portfolio.  While management uses available information to
recognize losses on loans, future additions to the reserve may be necessary
based on changes in economic conditions.  Additionally, various regulatory
agencies, as an integral part of the examination process, periodically review
Citizens Bank's reserve for possible loan losses.  Such agencies may require
Citizens Bank to add to the reserve for possible loan losses based on their
judgments and interpretations about information available to them at the time of
their examinations.

BANK PREMISES AND EQUIPMENT

Bank premises and equipment are stated at cost, less accumulated depreciation. 
Depreciation of premises and equipment are computed over the expected lives of
the assets, using both straight-line and accelerated methods.  Estimated useful
lives are seven to 39 years for premises and five to seven years for furniture,
fixtures, and equipment.  Expenditures for major renewals and betterments of
bank premises and equipment are capitalized, and those for maintenance and
repairs are expensed as incurred.

Shipman adopted the provisions of Statement of Financial Account Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of," ("FAS 121") on January 1, 1996.  FAS 121 requires
that long-lived assets, such as bank premises and equipment, and certain
identifiable intangible assets be reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable.  Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset.  If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets.  Assets to be disposed
of are reported at the lower of the carrying amount or fair value less selling
costs.  Shipman's adoption of FAS 121 in 1996 had no effect on the Company's
consolidated financial position, results of operations or liquidity.

OTHER REAL ESTATE OWNED

Other real estate owned represents property acquired through foreclosure, or 
deeded to Citizens Bank in lieu of foreclosure, for loans on which the 
borrowers have defaulted as to payment of principal and interest.  Properties 
acquired are initially recorded at the lower of Citizens Bank's cost (less 
estimated selling costs) or fair value of the property acquired, and carried 
in other assets in the consolidated balance sheets.  Valuations are 
periodically performed by management, and an allowance for losses is 
established by means of a charge to noninterest expense if the carrying value 
of a property exceeds its fair value less estimated selling costs.  
Subsequent increases in the fair value less estimated selling costs are 
recorded through a reversal of the allowance, but not below zero.  Costs 
related to development and improvement of property are capitalized, while 
costs relating to holding the property are expensed.

INCOME TAXES

Shipman and Citizens Bank file consolidated Federal and state income tax 
returns.  Applicable income taxes are computed based on reported income and 
expenses, adjusted for permanent differences between reported and taxable 
income.

Shipman uses the asset and liability method of accounting for income taxes, in
which deferred tax assets and liabilities are recognized for the estimated
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases.  Deferred tax assets and liabilities are measured using
enacted tax rates in effect for the year in which those temporary differences
are expected to be recovered or settled.  The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in the period which includes
the enactment date.

MORTGAGE BANKING OPERATIONS

Citizens Bank provides long-term, fixed rate financing on residential real
estate.  Originated loans are sold in the secondary market without recourse to
the Federal Home Loan Mortgage Corporation (the "FHLMC").  Upon receipt of an
application for a real estate loan, Citizens Bank locks in an interest rate with
the FHLMC, and at the same time Citizens Bank locks into an interest rate with
the customer.  This practice minimizes Citizens Bank's exposure to risk
resulting from interest rate fluctuations.  Upon disbursement of the loan
proceeds to the customer, the loan is delivered to the FHLMC.  Sales proceeds
are generally received two to seven days later.  Therefore, no loans held for
sale are included in Citizens Bank's loan portfolio at any point in time, except
those loans for which the sale proceeds have not yet been received.  Such loans
are maintained at the lower of cost or market value, based on the outstanding
commitment from the FHLMC for such loans.

Loan origination fees are recognized upon the sale of the related loans and 
included in the consolidated statements of income as noninterest income from 
mortgage banking operations. Additionally, loan administration fees, 
representing income earned from servicing these loans sold in the secondary 
market, are calculated on the outstanding principal balances of the loans 
serviced and recorded as noninterest income as earned.

In May 1995, the Financial Accounting Standards Board issued Statement of 
Financial Accounting Standards No. 122, "Accounting for Mortgage Servicing 
Rights" ("FAS 122"), which requires that a mortgage banking enterprise 
recognize as separate assets the rights to service mortgage loans for others 
at the origination or purchase date of the loan, when the enterprise has a 
definitive plan to sell or securitize the loans and retain the mortgage 
servicing rights, assuming the fair value of the loans and servicing rights 
may be practically estimated. Otherwise, servicing rights should be 
recognized when the underlying loans are sold or securitized, using an 
allocation of total cost of the loans based on the relative fair values at 
the date of sale. FAS 122 also requires an assessment of capitalized mortgage 
servicing rights for impairment to be based on the current fair value of 
those rights. In connection with the establishment of Citizens Bank's 
mortgage banking operations in May 1996, the provisions of FAS 122 were 
adopted. The value of mortgage servicing rights is determined based on the 
present

value of estimated future cash flows, using assumptions as to current market 
discount rate, prepayment speeds and servicing costs per loan. Mortgage 
servicing assets are amortized in proportion to, and over the period of 
estimated net servicing income as an other noninterest expense.

At December 31, 1997 and 1996, Citizens Bank serviced loans totaling 
$4,620,636 and $1,721,126, respectively, and the net unamortized balances of 
mortgage servicing rights were $35,272 and $16,117, respectively. No 
valuation reserve was required on such assets on either date, in that the 
fair values thereof, determined by comparison to the fair value of loan 
portfolios with similar characteristics, exceeded the carrying amounts 
included in other assets on Shipman's consolidated balance sheets.

FINANCIAL INSTRUMENTS

For purposes of information included in Note 12 regarding disclosures about 
financial instruments, financial instruments are defined as cash, evidence of 
an ownership interest in an entity, or a contract that both:
     
(a)  Imposes on one entity a contractual obligation to deliver cash or 
     another financial instrument to a second entity or to exchange other 
     financial instruments on potentially unfavorable terms with the second 
     entity, and

(b)  Conveys to that second entity a contractual right to receive cash or 
     another financial instrument from the first entity or to exchange other 
     financial instruments on potentially favorable terms with the first 
     entity.

Shipman adopted the provisions of Statement of Financial Accounting Standards 
No. 125, "Transfer and Servicing of Financial Assets and Extinguishments of 
Liabilities" ("FAS 125"), on January 1, 1997.  FAS 125 provides accounting 
and reporting standards for transfers and servicing of financial assets and 
extinguishments of liabilities based on consistent application of a financial 
components approach that focuses on control.  FAS 125 distinguishes transfers 
of financial assets that are sales from transfers that are secured 
borrowings. Adoption of FAS 125 did not have a material impact on Shipman's 
financial position, results of operations, or liquidity.

NOTE 2 - CASH AND DUE FROM BANKS

Citizens Bank is required to maintain certain daily reserve balances on hand 
in accordance with regulatory requirements.  The reserve balances maintained 
in accordance with such requirements at December 31, 1997 and 1996 were 
approximately $52,000 and $97,000, respectively.

Citizens Bank's equity securities include common stock of the Federal Home Loan
Bank of Chicago, which is administered by the Federal Housing Finance Board.  As
a member of the Federal Home Loan Bank System, Citizen Bank is required to
maintain an investment in the capital stock of the Federal Home Loan Bank of
Chicago in an amount equal to the greater of 1% of the aggregate outstanding
balance of loans secured by dwelling units at the beginning of each year or 0.3%
of the total assets of Citizen Bank.  The stock is recorded at cost, which
represents redemption value.

The carrying value of debt securities pledged to secure public funds, borrowings
from the Federal Home Loan Bank of Chicago, and for other purposes amounted to
approximately $3,603,000 and $5,957,000 at December 31, 1997 and 1996,
respectively.

During 1996, certain available-for-sale debt securities were sold for proceeds
totaling $2,574,363, resulting in gross losses of $35,027.  No securities were
sold in 1997.

Citizens Bank grants commercial, industrial, residential, agricultural and
consumer loans and direct financing leases throughout Macoupin and Jersey
counties in Illinois.  With the exception of agricultural credits, Citizens Bank
does not have any particular concentration of credit in any one economic sector;
however, a substantial portion of the portfolio is concentrated in and secured
by real estate in the two-county area.  The ability of Citizens Bank's borrowers
to honor their contractual obligations is dependent upon the local economies and
their effect on the real estate market.

At December 31, 1997 and 1996, Citizens Bank had loans outstanding to the
agricultural sector of $8,414,978 and $9,006,787, respectively, which comprise
27.0% and 29.2%, respectively, of Citizens Bank's total loan portfolio. 
Additionally, Citizens Bank's direct financing leases involve agricultural
equipment, which is being leased to local area farmers.  Citizens Bank's
agricultural credits are concentrated in the two-county area in Illinois and are
generally fully secured with either growing crops, farmland, livestock and/or
machinery and equipment.  Such loans are subject to the overall national effects
of the agricultural economy, as well as the local effects relating to their
Illinois location.

The aggregate amount of loans to executive officers and directors and loans made
for the benefit of executive officers and directors was $957,815 and $1,334,155
at December 31, 1997 and 1996, respectively.  Such loans were made in the normal
course of business on substantially the same terms, including interest rates and
collateral, as those prevailing at the same time for comparable transactions
with other persons, and did not involve more than the normal risk of
collectibility.  A summary of activity for loans to executive officers and
directors for the year ended December 31, 1997 is as follows:

Shipman is required to provide a valuation reserve on deferred tax assets 
when it is more likely than not that some portion of the assets will not be 
realized. Shipman has not established a valuation reserve at December 31, 
1997 and 1996, due to management's belief that all criteria for recognition 
have been met, including the existence of a history of taxes paid sufficient 
to support the realization of deferred tax assets.

The term notes payable to the Federal Home Loan Bank of Chicago represent 
Citizens Bank's borrowings under a term notes payable line of credit with the 
Federal Home Loan Bank of Chicago. These term notes mature at various dates 
through 2008 at rates ranging from 5.91% to 6.95%. The weighted average 
interest rate of Citizens Bank's outstanding borrowings with the Federal Home 
Loan Bank of Chicago at December 31, 1997 was 6.41%. The weighted average 
interest rate paid on this debt was 6.48% for each of the years ended 
December 31, 1997 and 1996. The notes payable with the Federal Home Loan Bank 
of Chicago are fully-collateralized by debt securities.

Shipman obtained a note payable from an unaffiliated  financial institution, 
originated on September 11, 1996, to pay off an existing line of credit note 
which had been obtained in August 1995 to repurchase Company common stock 
totaling $1,248,885. Subsequent principal payments were made in 1996 from 
proceeds received from the sale of treasury stock and a special dividend paid 
by Citizens Bank to Shipman.

The existing note payable to an unaffiliated financial institution has a 
maturity of September 5, 1998. Interest is payable quarterly at 0.50% below 
the prime commercial rate (8.50% at December 31, 1997 and 8.25% at

NOTE 9 - EMPLOYEE  BENEFIT PLANS

EMPLOYEE 401 (k) PROFIT SHARING AND STOCK OWNERSHIP PLAN

Citizens Bank sponsors a contributory 401(k) profit sharing plan with 
provision for Citizens Bank matching contributions.  All employees meeting 
certain age and service requirements are eligible to participate in the plan. 
 Citizens Bank will match an employee's contribution up to a 6% maximum 
contribution for any one employee, with all Citizens Bank matching 
contributions to go toward the purchase of Shipman common stock under an 
employee stock ownership plan. Citizens Bank matching contributions totaled 
$37,184 and $24,138 in 1997 and 1996, respectively.  At December 31, 1997 and 
1996, the employee stock ownership plan held 483.7962 shares of Shipman 
common stock.

INCENTIVE DEFERRAL PLAN FOR DIRECTORS

Effective January 1996, Citizens Bank adopted an Incentive Deferral Plan for 
each of its directors, allowing such directors to defer their current 
compensation earned as directors, with Citizens Bank agreeing to pay to such 
directors, or their designated beneficiaries or survivors, the total amount 
of deferred compensation plus accumulated interest at or following 
retirement. Under the Incentive Deferral Plan, interest is added to the 
accumulated deferred compensation at a periodic compound rate equal to 
Citizens Bank's return on equity for the preceding fiscal year.  The 
directors are expected to continue to render their normal service as 
directors to the Citizens Bank from the date of the plan's inception until 
retirement.

The Incentive Deferral Plan stipulates that, upon disability or death prior 
to retirement, the affected director (or his or her designated beneficiaries 
or survivors) would receive a pre-determined benefit.  If the director dies 
after benefit payments commence but before receiving all such payments, 
Citizens Bank shall pay the remaining accumulated benefits to the director's 
beneficiary at the same time and in the same amounts as would have been paid 
had the director survived.  Payments under the Incentive Deferral Plan may be 
made in a lump sum or periodically over a specified time period, with 
interest.

To fund the individual agreements with each director covered under the 
Incentive Deferral Plan, Citizens Bank has purchased flexible premium 
universal life insurance policies on the lives of such directors, (payable 
upon death to Citizens Bank).  Premiums for such policies are payable over 
the first five years of the plan with no further premiums or other payments 
due thereafter. Each life insurance policy has a cash surrender value feature 
which allows Citizens Bank to receive an amount in cash upon cancellation or 
lapse of the policy. The cash surrender value of the policies, which is 
included in other assets in the consolidated balance sheets, increases 
monthly, based upon an interest factor, net of mortality, administration and 
early termination costs that are inherent in the contracts.

                      Notes to Consolidated Financial Statements

Citizens Bank recognizes annual compensation expense equal to the sum of the 
compensation deferred under the Incentive Deferral Plan by the affected 
directors, plus interest applied to the accumulated balance of the deferred 
compensation and compounded interest at the beginning of the period. A 
liability is included in other liabilities in the consolidated balance sheets 
equal to the sum of all deferrals and interest accumulated to date.  

EXECUTIVE SALARY CONTINUATION PLAN

Citizens Bank maintains a non-qualified Executive Salary Continuation Plan for
certain key officers which provides for the payment of fixed annual retirement
benefits to such officers, or their designated beneficiaries or survivors, for
15 years following their  attainment of the normal retirement age of 65.  The
Executive Salary Continuation Plan also provides for benefits in the event of
the executive's termination, early retirement, death or disability.

As an unfunded plan, no assets are specifically set aside or held in trust 
for the payment of benefits under the Executive Salary Continuation Plan. 
Participants in the plan have no rights beyond those of an unsecured creditor 
of Citizens Bank.

To fund the individual agreements with each officer under the Executive Salary
Continuation Plan, Citizens Bank has purchased flexible premium universal life
insurance policies on the lives of such officers (payable upon death to Citizens
Bank).  Each life insurance policy has a cash surrender value feature which
allows Citizens Bank to receive an amount of cash upon cancellation or lapse of
the policy.  The cash surrender value of the polices, which is included in other
assets in the consolidated balance sheets, increases monthly, based on an
interest factor, net of mortality, administration and early termination costs
that are inherent in the contracts.

Benefit expenses under the Executive Salary Continuation Plan are recognized on
an annual basis in an amount sufficient, as computed using the interest method,
to fully accrue the net present value of future benefit payments to be made to
each participant by the normal retirement dates of such participants.  The
discount rate used in such calculations was 8.5% for both 1997 and 1996.  The
amounts charged to expense under the Executive Salary Continuation Plan were
$50,556 and $54,426 for 1997 and 1996, respectively.  The associated accrued
liability, which is included in other liabilities in the consolidated balance
sheets, was $228,245 and $193,130 at December 31, 1997 and 1996, respectively.

NOTE 10 - LITIGATION

During the normal course of business, various legal claims have arisen which, 
in the opinion of management, will not result in any material liability to 
Shipman. In January 1998, a pending claim against Citizens Bank was settled 
for approximately $47,500. Accordingly, this amount has been recorded in 
other liabilities and other noninterest expense in Shipman's consolidated 
financial statements at December 31, 1997.

NOTE 11 - PARENT COMPANY FINANCIAL INFORMATION

Citizens Bank dividends are the principal source of funds for the payment of 
dividends by Shipman to its stockholders and for debt servicing.  Citizens 
Bank is subject to regulations by regulatory authorities which require the 
maintenance of minimum capital requirements.  As of December 31, 1997, there 
are no regulatory restrictions, other than maintenance of minimum capital 
standards, as to the amount of dividends Citizens Bank may pay.

NOTE 12 - DISCLOSURES ABOUT FINANCIAL INSTRUMENTS

Citizens Bank issues financial instruments with off-balance-sheet risk in the
normal course of the business of meeting the financing needs of its customers. 
These financial instruments include commitments to extend credit and standby
letters of credit and may involve, to varying degrees, elements of credit risk
in excess of the amounts recognized in the consolidated balance sheets.  The
contractual amounts of those instruments reflect the extent of involvement
Citizens Bank has in particular classes of financial instruments.

                  Notes to Consolidated Financial Statements

Shipman's exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for commitments to extend credit and standby
letters of credit is represented by the contractual amount of those instruments.
Citizens Bank uses the same credit policies in making commitments and
conditional obligations as it does for financial instruments included on the
balance sheet.  At December 31, 1997 and 1996, Shipman's off-balance sheet
financial instruments consisted solely of commitments to extend credit totaling
$2,978,909 and $2,502,472, respectively. 

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract.  Of the
total commitments to extend credit at December 31, 1997, $2,566,534 represented
fixed rate loan commitments.  Commitments generally have fixed expiration dates
or other termination clauses and may require payment of a fee.  Since certain of
the commitments may expire without being drawn upon, the total commitment
amounts do not necessarily represent future cash requirements.  Citizens Bank
evaluates each customer's creditworthiness on a case-by-case basis.  The amount
of collateral obtained, if deemed necessary by Citizens Bank upon extension of
credit, is based on management's credit evaluation of the borrower.  Collateral
held varies, but is generally residential or income-producing commercial
property or equipment.

Standby letters of credit (for which no such instruments were outstanding at
December 31, 1997 and 1996) are conditional commitments issued by Citizens Bank
to guarantee the performance of a customer to a third party.  Such guarantees
are primarily issued to support public and private borrowing arrangements.  The
credit risk involved in issuing letters of credit is essentially the same as
that involved in extending loan facilities to customers.

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate such
value:

CASH AND OTHER SHORT-TERM INSTRUMENTS
For cash and due from banks (including interest-bearing deposits with financial
institutions), Federal funds sold, and accrued interest receivable (payable) the
carrying amount is a reasonable estimate of fair value, as such instruments are
due on demand and/or reprice in a short time period.

INVESTMENTS IN DEBT AND EQUITY SECURITIES
Fair values are based on quoted market prices or dealer quotes.

                  Notes to Consolidated Financial Statements

LOANS
For certain homogeneous categories of loans, such as residential mortgages and
other consumer loans, fair value is estimated using the quoted market prices for
securities backed by similar loans, adjusted for differences in loan
characteristics.  The fair value of other types of loans is estimated by
discounting the future cash flows using the current rates at which similar loans
would be made to borrowers with similar credit ratings and with the same
remaining maturities.

INSURANCE CONTRACTS
The fair value of insurance contracts is based on quotes of cash surrender
values provided by the carriers.

DEPOSITS
The fair value of demand deposits, savings accounts, and interest-bearing
transaction account deposits is the amount payable on demand at the reporting
date.  The fair value of fixed-maturity certificates of deposit is estimated
using the rates currently offered for deposits of similar remaining maturities.

NOTES PAYABLE
Rates currently available to Shipman for debt with similar terms and remaining
maturities are used to estimate the fair value of existing debt.

COMMITMENTS TO EXTEND CREDIT AND STANDBY LETTERS OF CREDIT
The fair value of commitments to extend credit and standby letters of credit are
estimated using the fees currently charged to enter into similar agreements,
taking into account the remaining terms of the agreements, the likelihood of the
counterparties drawing on such financial instruments, and the present
creditworthiness of such counterparties.  Shipman believes such commitments have
been made on terms which are competitive in the market in which it operates.

NOTE 13 - REGULATORY MATTERS

Shipman and Citizens Bank are subject to various regulatory capital requirements
administered by the Federal banking agencies.  Failure to meet minimum capital
requirements can initiate certain mandatory, and possible additional
discretionary, actions by regulators that, if undertaken, could have a direct
material effect on Shipman's consolidated financial statements.  Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
Shipman and Citizens Bank must meet specific capital guidelines that involve
quantitative measures of Shipman's and Citizens Bank's assets, liabilities, and
certain off-balance sheet items as calculated under regulatory accounting
practices.  Shipman's and Citizens Bank's capital amounts and classification are
also subject to qualitative judgments by the regulators about components, risk
weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require Shipman and Citizens Bank to maintain minimum amounts and ratios (set
forth in the table below) of total and Tier 1 capital (as defined in the
regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as
defined) to average assets (as defined).  Shipman management believes, as of
December 31, 1997, that Shipman and Citizens Bank met all capital adequacy
requirements to which they were subject.

As of December 31, 1997, the most recent notification from applicable regulatory
authorities categorized Shipman and Citizens Bank as well capitalized under the
regulatory framework for prompt corrective action.  To be categorized as well
capitalized, Shipman and Citizens Bank must maintain minimum total risk-based,
Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following
table.  There are no conditions or events since those notifications that Shipman
management believes have changed Shipman's and Citizens Bank's respective
categories.

Acquisition Corp shall be merged with and into Shipman pursuant to the 
provisions of, and with the effect provided in, the Illinois Business 
Corporation Act of 1983, as amended (the "Illinois Code"), and Shipman shall 
be the corporation resulting from such merger (the "Surviving Corporation").  
As a result of the Merger, each share of Shipman Common Stock issued and 
outstanding immediately prior to the Effective Time, other than Dissenting 
Shares (as defined below), will be converted into the right to receive the 
number of shares of CNB Common Stock or the amount of cash or a combination 
of both, as provided in Section 3.2.  

     SECTION 2.2    EFFECT OF MERGER.  (a) At the Effective Time, Acquisition 
Corp shall be merged with and into Shipman and Shipman shall be the Surviving 
Corporation.  Shipman and Acquisition Corp are sometimes referred to 
collectively herein as the "Merging Corporations."
     
     (b)  Without limiting the generality of the foregoing, at the Effective 
Time, the Surviving Corporation shall thereupon and thereafter possess all 
the rights, privileges, immunities and franchises, as of a public or a 
private nature, of each of the Merging Corporations, and all property, real, 
personal and mixed, and all debts due on whatever account, including 
subscriptions to shares, and all other choses in action, and all and every 
other interest, of or belonging to or due to each of the Merging 
Corporations, shall be taken and deemed to be transferred to and vested in 
the Surviving Corporation without further act or deed; and the title to any 
real estate, or any interest therein, vested in any of such corporations 
shall not revert or be in any way impaired by reason of the Merger.  The 
Surviving Corporation shall assume and thenceforth be responsible and liable 
for all the liabilities and obligations (including all obligations of 
indemnification, if any) of each of the Merging Corporations and any claim 
existing or action or proceeding pending by or against any of the Merging 
Corporations may be prosecuted to judgment as if the Merger had not taken 
place, or the Surviving Corporation may be substituted in its place. Neither 
rights of creditors nor any liens upon the property of any of the Merging 
Corporations shall be impaired by the Merger.

     SECTION 2.3    ARTICLES OF INCORPORATION.  From and after the Effective 
Time and until amended as provided by law, the articles of incorporation of 
the Surviving Corporation shall be the articles of incorporation of 
Acquisition Corp as in effect immediately prior to the Effective Time.

<PAGE>

     SECTION 2.4    BYLAWS.  From and after the Effective Time and until 
amended as provided by law, the bylaws of the Surviving Corporation shall be 
the bylaws of Acquisition Corp as in effect immediately prior to the 
Effective Time.

     SECTION 2.5    DIRECTORS AND OFFICERS.  The directors and officers of 
Acquisition Corp immediately prior to the Effective Time shall serve as the 
directors and officers of the Surviving Corporation until their successors 
shall have been elected or appointed and shall have qualified in accordance 
with the Illinois BCA and the articles of incorporation and bylaws of the 
Surviving Corporation.
     
     SECTION 2.6    CLOSING.  (a) The closing of the Purchase (the "Closing") 
shall occur at the offices of CNB located at West Side Square, Carlinville, 
Illinois, on a date which is mutually acceptable to CNB and Shipman, but if 
they fail to agree, at 10:00 a.m. on the date which is five Business Days 
after the first date on which all required approvals or consents of the 
Regulatory Authorities for the Contemplated Transactions have been received 
and all statutory waiting periods relating to such approvals have expired, or 
at such other time and place as CNB and Shipman may agree in writing (the 
"Closing Date").  Subject to the provisions of Article 10, failure to 
consummate the Merger on the date and time and at the place determined 
pursuant to this Section will not result in the termination of this Agreement 
and will not relieve any party of any obligation under this Agreement.

          (b)  The parties hereto agree to file on the Closing Date 
appropriate articles of merger, as contemplated by Section 11.25 of the 
Illinois Code (the "Articles of Merger"), with the Secretary of State of the 
State of Illinois. The Merger shall be effective upon the close of business 
on the day when the Articles of Merger have been accepted for filing by the 
Secretary of State of the State of Illinois (the "Effective Time").

                        TREATMENT OF AND PAYMENT FOR SHARES
                                          
     SECTION 3.1    TREATMENT OF ACQUISITION CORP STOCK.  Each share of 
common stock, $10.00 par value per share, of Acquisition Corp issued and 
outstanding immediately prior to the Effective Time shall remain issued and 
outstanding at the Effective Time, shall be unaffected by the Merger and 
shall thereafter represent all of the issued and outstanding stock of the 
Surviving Corporation.

     SECTION 3.2    TREATMENT OF SHIPMAN COMMON STOCK.  The conversion of
Shipman Common Stock into the right to receive CNB Common Stock and/or cash
shall be governed by the provisions of this Section.

          (a)  Subject to the provisions of this Article and based upon a 
total of 32,035.8291 shares of Shipman Common Stock issued and outstanding 
immediately prior to the Effective Time (including for this purpose, the 
number of shares of Shipman Common Stock issuable upon the exercise of any 
executory Contracts for the issuance of any additional stock, including 
warrants and options) (collectively, the "Shipman Outstanding Stock"), by 
virtue of the Merger and without any action on the part of the holder 
thereof, at the Effective Time, each share of Shipman Common Stock issued and 
outstanding immediately prior to the Effective Time shall be deemed 
surrendered and automatically converted into and shall thereafter represent 
either, or a combination of:

               (i)  the right to receive an amount in cash equal to $190 (the 
"Cash Price Per Share"); or

               (ii) the right to receive and be exchangeable for two (2) 
shares of CNB Common Stock (the "Exchange Shares").

                                        A-12
<PAGE>

          (b)  Subject to the provisions of this Section, each record holder 
of shares of Shipman Common Stock (other than Dissenting Shareholders) will 
be entitled to: (i) elect to receive cash for all of such shares ("Cash 
Election"); (ii) elect to receive CNB Common Stock for all of such shares 
("Stock Election"); (iii) elect to receive CNB Common Stock for a stated 
percentage of such shares ("Partial Stock Election") and to receive cash for 
a stated percentage of such shares ("Partial Cash Election"); or (iv) 
indicate by such holders' action or inaction that such record holder has no 
preferences as to the receipt of cash or CNB Common Stock for such shares 
("Non-Election").  All such elections shall be made on a form designed for 
that purpose and mutually agreeable to Shipman and CNB (a "Form of 
Election").  Record holders of Shipman Common Stock who hold such shares as 
nominees, trustees or in any other representative capacities may submit 
multiple Forms of Election, provided that such record holder certifies that 
each such Form of Election covers the shares of Shipman Common Stock held by 
each such record holder for a particular beneficial owner.

          (c)  Notwithstanding anything contained herein to the contrary, the 
sum of (i) the number of shares of Shipman Common Stock to be converted 
pursuant to this Agreement into the right to receive cash, plus (ii) the 
number of Dissenting Shares (as defined below), shall not be more than 30% of 
the Shipman Outstanding Stock (the "Maximum Cash Payment Number").  If the 
number of shares of Shipman Common Stock for which a Cash Election or a 
Partial Cash Election was made (collectively, the "Cash Election Shares"), 
plus the number of Dissenting Shares, exceeds the Maximum Cash Payment 
Number, then the consideration to be received by shareholders of Shipman who 
have made a Cash Election or a Partial Cash Election shall be adjusted in the 
manner provided below.

          (d)  If the number of Cash Election Shares, plus the number of 
Dissenting Shares, exceeds the Maximum Cash Payment Number, all shares of 
Shipman Common Stock for which a Stock Election or a Partial Stock Election 
were made (collectively, the "Stock Election Shares") shall be converted into 
the right to receive CNB Common Stock, and the Cash Election Shares shall be 
converted into the right to receive CNB Common Stock and cash in the 
following manner.  Each Cash Election Share shall be converted into the right 
to receive:

               (i)  an amount in cash (rounded to the nearest cent), without 
interest, equal to the product of (A) the Cash Price Per Share and (B) a 
fraction ("Cash Fraction"), the numerator of which shall be the Maximum Cash 
Payment Number and the denominator of which shall be the sum of the Cash 
Election Shares plus the Dissenting Shares; and

               (ii) a number of shares of CNB Common Stock equal to the 
product of:  (A) two (2); multiplied by (B) a fraction equal to one (1) minus 
the Cash Fraction.

          (e)  If the Cash Election Shares, plus the number of Dissenting 
Shares, is less than the Maximum Cash Payment Number, then each Cash Election 
Share shall be converted into the right to receive the Cash Price Per Share. 
For purposes of this Agreement, each Non-Election shall be treated as a Stock 
Election.

                                        A-13
<PAGE>

          (f)  After the Effective Time, no holder of Shipman Common Stock 
which is issued and outstanding immediately prior to the Effective Time will 
have any rights in respect of such Shipman Common Stock except to receive 
cash, shares of CNB Common Stock or a combination thereof for the shares of 
Shipman Common Stock converted as provided in this Section, or to receive 
payment for such shares of Shipman Common Stock in the manner and to the 
extent provided in Section 17-6712 of the Illinois Code.

     SECTION 3.3    STEPS OF TRANSACTION.  (a) After the date that notice is 
sent to shareholders of Shipman (the "Mailing Date") of the special meeting 
of shareholders to be held pursuant to Section 6.9 (the "Special Meeting"), 
CNB shall mail or cause to be mailed to each then current holder of record of 
a certificate or certificates representing outstanding shares of Shipman 
Common Stock (the "Certificates") transmittal materials for use in 
surrendering such Certificates, including:  (i) a Form of Election which 
shall allow holders of Shipman Common Stock to make the Cash Election, Stock 
Election, Partial Cash Election or Partial Stock Election, shall provide 
instructions for the transmittal of the Certificates and shall specify that 
delivery shall be effected, and risk of loss and title to the Certificates 
shall pass, only upon delivery of the Certificates (or a lost certificate 
affidavit and a bond in a form reasonably acceptable to CNB); and (ii) 
instructions for use in making a Stock Election, Cash Election, Partial Cash 
Election or Partial Stock Election and effecting the surrender of the 
Certificates in exchange for either cash or CNB Common Stock.  Pursuant to 
the terms of a mutually agreeable exchange agent agreement, the parties 
hereto agree to appoint the Carlinville National Bank, a national banking 
association with its main office located in Carlinville, Illinois, as 
exchange agent (the "Exchange Agent") for the parties to effect the surrender 
of the Certificates in exchange for either cash, CNB Common Stock or a 
combination thereof.  CNB shall use all reasonable efforts to mail or cause 
to be mailed the Form of Election to all persons who become holders of 
Shipman Common Stock subsequent to the Mailing Date and no later than the 
close of business of the Business Day prior to the Election Deadline (as 
defined below). Any previously submitted Form of Election may be revoked by a 
written notice thereof delivered to the Exchange Agent and signed by the 
holder submitting such Form of Election provided that such written notice is 
received by the Exchange Agent on or before the Election Deadline.

          (b)  Elections by holders of Shipman Common Stock shall be made by 
mailing or delivering to the Exchange Agent a properly completed and executed 
Form of Election and the Certificates.  A properly completed Form of Election 
must be received by the Exchange Agent by 5:00 p.m. on the date which is 
seven (7) days following the date of the Special Meeting (the "Election 
Deadline") to be effective.  CNB shall have the discretion, which it may 
delegate in whole or in part to the Exchange Agent, to determine whether 
Forms of Election have been properly completed, signed and submitted and to 
disregard any defects it determines are immaterial.  The decision of CNB or 
the Exchange Agent on such matters shall be conclusive and binding.  Neither 
CNB nor the Exchange Agent shall be under any obligation to notify any person 
of any defect in a Form of Election submitted to the Exchange Agent.  The 
Exchange Agent shall make all computations contemplated by Section 3.2, 
PROVIDED, HOWEVER, that all such computations shall be verified by Cummings & 
Associates, P.C. and shall thereafter be conclusive and binding on the 
holders of Shipman Common Stock.

                                        A-14
<PAGE>

          (c)  For the purposes of this Agreement, a holder of Shipman Common 
Stock who does not submit a Form of Election which is received by the 
Exchange Agent prior to the Election Deadline shall be deemed to have made a 
Non-Election.  If CNB or the Exchange Agent shall determine that any 
purported Cash Election, Partial Cash Election, Stock Election or Partial 
Stock Election was not properly made, such purported election shall be deemed 
to be of no force and effect and the shareholder making such purported Cash 
Election, Partial Cash Election, Stock Election or Partial Stock Election 
shall for purposes hereof be deemed to have made a Non-Election.
          
         (d)  As promptly as practicable after the Effective Time, CNB shall 
cause the Exchange Agent to deliver to each holder of Shipman Common Stock 
who has theretofore submitted an effective Form of Election accompanied by 
the Certificates covered by such Form of Election:  (i) cash in an amount 
equal to the product of the Cash Price Per Share times the number of shares 
of Shipman Common Stock theretofore represented by the Certificates to be 
converted into cash; (ii) certificates representing the number of whole 
shares of CNB Common Stock into which the shares of Shipman Common Stock 
theretofore represented by the Certificates so surrendered in exchange for 
CNB Common Stock were converted, plus cash as hereinafter provided for any 
fractional share of CNB Common Stock which such holder would have been 
entitled to receive; or (iii) both cash and shares of CNB Common Stock 
pursuant to a Partial Cash Election, Partial Stock Election or as otherwise 
provided by Section 3.2.

          (e)  As promptly as practicable after the Effective Time, CNB shall 
send to each holder of record of Shipman Common Stock immediately prior to 
the Effective Time who has not previously submitted his or her Certificates, 
additional transmittal materials for use in surrendering such Certificates to 
the Exchange Agent and instructions for use in effecting such surrender in 
exchange for cash.

          (f)  No dividends or other distributions declared after the 
Effective Time with respect to CNB Common Stock which are payable to 
shareholders of record of CNB after the Effective Time shall be paid to a 
shareholder of Shipman who is entitled to receive shares of CNB Common Stock 
pursuant to this Agreement and who holds any unsurrendered Shipman 
Certificate with respect to CNB Common Stock represented thereby, until such 
shareholder shall surrender such Certificate.  Until so surrendered and 
exchanged, each such outstanding Certificate shall for all purposes, other 
than the payment of dividends or other distributions, if any, to holders of 
record of shares of CNB Common Stock represent the shares of CNB Common Stock 
into and for which such shares have been so converted; PROVIDED, HOWEVER, 
that upon surrender of a Certificate, there shall be paid to the record 
holder or holders of the Certificate, the amount, without interest thereon, 
of such dividends and other distributions, if any, which theretofore have 
become payable with respect to the number of whole shares of CNB Common Stock 
represented by such Certificate.

          (g)  No fractional shares of CNB Common Stock shall be issued upon 
the surrender for exchange of Certificates; no dividend or distribution of 
CNB shall relate to any fractional share interest; and such fractional share 
interests will not entitle the owner thereof to vote or to any rights of a 
shareholder of CNB.  Instead, each holder of shares of Shipman

                                        A-15
<PAGE>

Common Stock who has a fractional interest in shares of CNB Common Stock 
arising upon the conversion or exchange of shares of Shipman Common Stock for 
CNB Common Stock shall, at the time of surrender of the Certificates 
theretofore representing Shipman Common Stock, be paid by CNB an amount in 
cash, without interest, determined by multiplying such fractional share of 
CNB Common Stock by the Cash Price Per Share.

          (h)  All rights to receive cash and shares of CNB Common Stock into 
and for which shares of Shipman Common Stock shall have been converted and 
exchanged pursuant to this Agreement, shall be deemed to have been paid or 
issued, as the case may be, in full satisfaction of all rights pertaining to 
such converted and exchanged shares of Shipman Common Stock.

          (i)  At the Effective Time, Shipman shall deliver a certified copy 
of a list of its shareholders to CNB after which there shall be no further 
registration or transfers on the stock transfer books of Shipman of the 
shares of Shipman Common Stock which were outstanding immediately prior to 
the Effective Time.  Any Person whose name does not appear upon such list who 
submits Certificates to the Exchange Agent shall be entitled to receive no 
shares of CNB Common Stock or cash, and such Certificates shall be canceled.

          (j)  If any cash is to be paid to, or a certificate representing 
shares of CNB Common Stock is to be issued in the name of, a Person other 
than the Person in whose name the Certificate surrendered in exchange 
therefor is registered, it shall be a condition of the payment or issuance 
thereof that the Certificate so surrendered shall be properly endorsed, 
accompanied by all documents required to evidence and effect such transfer 
and otherwise in proper form for transfer and that the person requesting such 
payment or exchange shall pay to CNB any transfer or other taxes required by 
reason of the payment of such amount or issuance of a certificate 
representing shares of CNB Common Stock to or in the name of a Person other 
than the Person in whose name the Certificate surrendered in exchange 
therefor is registered, or otherwise required, or shall establish to the 
satisfaction of CNB that such tax has been paid or is not payable.

     SECTION 3.4    DISSENTING SHARES.  Notwithstanding anything to the 
contrary contained in this Agreement, to the extent appraisal rights are 
available to Shipman shareholders pursuant to the Illinois Code, any shares 
held by a person who objects to the Merger, whose shares either were not 
entitled to vote or were not voted in favor of the Merger and who complies 
with all of the provisions of the Illinois Code concerning the rights of such 
person to dissent from the Merger and to require appraisal of such person's 
shares and who has not withdrawn such objection or waived such rights prior 
to the Closing Date ("Dissenting Shares") shall not be converted pursuant to 
Section 3.2 but shall become the right to receive such consideration as may 
be determined to be due to the holder of such Dissenting Shares pursuant to 
the Illinois Code, PROVIDED, HOWEVER, that each Dissenting Share held by a 
person at the Effective Time who shall, after the Effective Time, withdraw 
the demand for appraisal or lose the right of appraisal, in either case 
pursuant to the Illinois Code shall be deemed to be converted, as of the 
Effective Time, into the Exchange Shares.

with Regulatory Authorities (a "Bank Call Report") for the years ended 
December 31, 1993, 1994, 1995 and 1996, and the quarters ended March 31, June 
30, and September 30, 1997; and

          (c)  all written agreements and understandings in effect or entered 
into by the Bank or Shipman with any Regulatory Authority since January 1, 
1994.

     The financial statements and the Bank Call Reports described in clauses 
(a) and (b) above (collectively, the "Financial Statements") have been 
prepared in accordance with all applicable rules and regulations and taken 
together, the Financial Statements fairly and accurately present in all 
material respects the respective financial position, assets, liabilities and 
results of operations of Shipman and the Bank as at the respective dates of 
and for the periods referred to in the Financial Statements.

     SECTION 4.8    BOOKS AND RECORDS.  The books of account, minute books, 
stock record books and other records of Shipman and the Bank are complete and 
correct in all material respects, and have been maintained in accordance with 
sound business practices and all applicable Legal Requirements, including the 
maintenance of any adequate system of internal controls.  The minute books of 
Shipman and the Bank contain accurate and complete records in all material 
respects of all meetings held of, and corporate action taken by, the 
shareholders, the Board of Directors, and committees of the Board of 
Directors of Shipman and the Bank, respectively, and no meeting of any such 
shareholders, Board of Directors or committee has been held for which minutes 
have not been prepared and are not contained in such minute books.  At the 
Closing, all of those books and records will be in the possession of Shipman 
and the Bank.

     SECTION 4.9    TITLE TO PROPERTIES.  Each of Shipman and the Bank has 
good and marketable title to all assets and properties, whether real or 
personal, tangible or intangible, which it purports to own subject to no 
liens, mortgages, security interests, encumbrances or charges of any kind 
except: (a) as noted in the most recent Shipman Financial Statement or on 
Schedule 4.9; (b) statutory liens for Taxes not yet delinquent or being 
contested in good faith by appropriate Proceedings and for which appropriate 
reserves have been established and reflected on the Financial Statements; (c) 
pledges or liens required to be granted in connection with the acceptance of 
government deposits, granted in connection with repurchase or reverse 
repurchase agreements or otherwise incurred in the Ordinary Course of 
Business; and (d) minor defects and irregularities in title and encumbrances 
which do not materially impair the use thereof for the purposes for which 
they are held and which would not reasonably be expected to have a material 
adverse effect on the financial condition, assets or business of Shipman or 
the Bank.  Each of Shipman and the Bank as lessee has the right under valid 
and existing leases to occupy, use, possess and control any and all of the 
respective property leased

                                        A-19
<PAGE>

by it.  All buildings and structures owned by each of Shipman and the Bank 
lie wholly within the boundaries of the real property owned or validly leased 
by it and do not encroach upon the property of, or otherwise conflict with 
the property rights of, any other Person.

     SECTION 4.10   CONDITION AND SUFFICIENCY OF ASSETS.  The buildings, 
structures and equipment of Shipman and the Bank are structurally sound, are 
in good operating condition and repair, and are adequate for the uses to 
which they are being put, and none of such buildings, structures or equipment 
is in need of maintenance or repairs except for ordinary, routine maintenance 
and repairs that are not material in nature or cost.  To the Knowledge of 
Shipman and the Bank, the buildings, structures and equipment of Shipman and 
the Bank are in compliance with the Americans with Disabilities Act of 1990, 
as amended ("ADA"), and the regulations promulgated thereunder at the 
effective date of each part of the ADA or the regulations, and are sufficient 
for the continued conduct of the business of Shipman and the Bank after the 
Closing in substantially the same manner as conducted prior to the Closing.

     SECTION 4.11   LOANS; LOAN LOSS RESERVE.  All loans and loan commitments 
extended by the Bank and any extensions, renewals or continuations of such 
loans and loan commitments (the "Shipman Loans") were made in accordance with 
customary lending standards of the Bank in the Ordinary Course of Business.  
The Shipman Loans are evidenced by appropriate and sufficient documentation 
and constitute valid and binding obligations to the Bank enforceable in 
accordance with their terms.  All such Shipman Loans are, and at the Closing 
will be, free and clear of any encumbrance or other charge and the Bank has 
complied, and at the Closing will have complied, in all material respects 
with all laws and regulations relating to such Loans.  The reserve for 
possible loan and lease losses shown on the September 30, 1997 Call Report of 
the Bank is and will be on the Closing Date adequate in all material respects 
under the standards applied by applicable Regulatory Authorities and based 
upon generally accepted accounting practices applicable to financial 
institutions to provide for possible or specific losses, net of recoveries 
relating to loans previously charged off, and contains and will contain an 
additional amount of unallocated reserves for unanticipated future losses at 
an adequate level.  To the Knowledge of Shipman and the Bank, none of the 
Shipman Loans is subject to any material offset or claim of offset, and the 
aggregate loan balances in excess of the Bank's reserve for loan and lease 
losses are, based on past loan loss experience, collectible in accordance 
with their terms and all uncollectible loans have been charged off.  
Notwithstanding anything in this Section to the contrary, all of the 
representations and warranties made in this Section are expressly subject to 
the exceptions set forth in Schedule 4.11.

     SECTION 4.12   UNDISCLOSED LIABILITIES; ADVERSE CHANGES.  Except as set 
forth in Schedule 4.12, neither Shipman nor the Bank has any liabilities or 
obligations of any nature (whether known or unknown and whether absolute, 
accrued, contingent, or otherwise) except for liabilities or obligations 
reflected or reserved against in the Financial Statements and current 
liabilities incurred in the Ordinary Course of Business since the respective 
dates thereof.  Since the date of the latest Financial Statement, there has 
not been any material adverse change in the business, operations, properties, 
assets, or condition of Shipman or the

                                        A-20
<PAGE>

Bank, and no event has occurred or circumstance exists that may result in 
such a material adverse change.

     SECTION 4.13   TAXES.  Each of Shipman and the Bank has duly filed or 
will duly file all Tax Returns required to be filed by it for all periods 
prior to the Closing Date, and each such Tax Return is complete and accurate 
in all material respects.  Each of Shipman and the Bank has paid, or made 
adequate provision for the payment of, all Taxes (whether or not reflected in 
Tax Returns as filed or to be filed) due and payable by Shipman or the Bank, 
or claimed to be due and payable by any Regulatory Authority, and is not 
delinquent in the payment of any Tax, except such Taxes as are being 
contested in good faith and as to which adequate reserves have been provided. 
There is no claim or assessment pending or Threatened against either Shipman 
or the Bank for Taxes owed by either of them.  No audit, examination or 
investigation related to Taxes paid or payable by Shipman or the Bank is 
presently being conducted or Threatened by any Regulatory Authority. 

     SECTION 4.14   COMPLIANCE WITH ERISA.  Except as set forth on Schedule 
4.14, all employee benefit plans (as defined in Section 3(3) of ERISA) 
established or maintained by Shipman or the Bank or to which Shipman or the 
Bank contributes, are in compliance in all material respects with all 
applicable requirements of ERISA, and are in compliance in all material 
respects with all applicable requirements (including qualification and 
non-discrimination requirements in effect as of the Closing) of the Code for 
obtaining the tax benefits the Code thereupon permits with respect to such 
employee benefit plans. For purposes of this Section, non-compliance with the 
Code and ERISA is material if such non-compliance would reasonably be 
expected to have a material adverse effect on the financial condition, assets 
or business of Shipman or the Bank. No such employee benefit plan has, or as 
of the Closing will have, any amount of unfunded benefit liabilities (as 
defined in Section 4001(a)(18) of ERISA) for which Shipman or the Bank would 
be liable to any Person under Title IV of ERISA if any such employee benefit 
plan were terminated as of the Closing, which amounts would be material to 
Shipman or the Bank.  Such employee benefit plans are funded in accordance 
with Section 412 of the Code (if applicable).  There would be no obligations 
which would be material to Shipman or the Bank under Title IV of ERISA 
relating to any such employee benefit plan that is a multi-employer plan if 
any such plan were terminated or if Shipman or the Bank withdrew from any 
such plan as of the Closing.

     SECTION 4.15   COMPLIANCE WITH LEGAL REQUIREMENTS.  Except as set forth 
in Schedule 4.15, each of Shipman and the Bank is, and at all times since 
January 1, 1996, has been, in full compliance with each Legal Requirement 
that is or was applicable to it or to the conduct or operation of its 
business or the ownership or use of any of its assets where the failure to be 
in such full compliance would reasonably be expected to have a material 
adverse effect on the financial condition of Shipman or the Bank.  No event 
has occurred or circumstance exists that (with or without notice or lapse of 
time):  (a) may constitute or result in a violation by Shipman or the Bank 
of, or a failure on the part of Shipman or the Bank to comply with, any Legal 
Requirement; or (b) may give rise to any obligation on the part of Shipman or 
the Bank to undertake, or to bear all or any portion of the cost of, any 
remedial action of any nature.  Except as set forth on Schedule 4.15, neither 
Shipman nor the Bank has

                                        A-21
<PAGE>

received, at any time since January 1, 1996, any notice or other 
communication (whether oral or written) from any Regulatory Authority or any 
other Person regarding:  (x) any actual, alleged, possible, or potential 
violation of, or failure to comply with, any Legal Requirement; or (y) any 
actual, alleged, possible, or potential obligation on the part of Shipman or 
the Bank to undertake, or to bear all or any portion of the cost of, any 
remedial action of any nature.

     SECTION 4.16   LEGAL PROCEEDINGS; ORDERS.  Schedule 4.16 is a true and 
correct list of all Proceedings and Orders pending, entered into or, to the 
Knowledge of Shipman and the Bank, Threatened against or affecting Shipman or 
the Bank or any of its respective assets or business, or the Contemplated 
Transactions, since January 1, 1996.  Except to the extent indicated in 
Schedule 4.16, no such pending or Threatened Proceeding or Order could, alone 
or in the aggregate, adversely affect the business, properties, assets, 
condition, prospects or rights of Shipman or the Bank and there is no fact 
which would provide a basis for any Proceeding or Order which could have such 
an effect.  To the Knowledge of Shipman and the Bank, no officer, director, 
agent, or employee of Shipman or the Bank is subject to any Order that 
prohibits such officer, director, agent, or employee from engaging in or 
continuing any conduct, activity or practice relating to the business of 
Shipman or the Bank.  Neither Shipman nor the Bank has received, at any time 
since January 1, 1996, any notice or other communication (whether oral or 
written) from any Regulatory Authority or any other Person regarding any 
actual, alleged, possible, or potential violation of, or failure to comply 
with, any Legal Requirement to which Shipman or the Bank, or any of the 
assets owned or used by either or them, is or has been subject.

     SECTION 4.17   ABSENCE OF CERTAIN CHANGES AND EVENTS.  Except as set

<PAGE>

terms and requirements of each Contract under which either Shipman or the

since January 1, 1996, has been, in full compliance with all applicable terms 
and requirements of such Contract. To the Knowledge of Shipman and the Bank,

breach of, or give Shipman, the Bank or other Person the right to declare a

or any of its respective assets that are pending or, to the Knowledge of

asserted failure of Shipman or the Bank, or any predecessor thereof, to 
comply (or the assertion of liability even if in compliance) with any Legal 
Requirements designed to minimize, prevent, punish or remedy the consequences 
of actions that damage or threaten the soil, land surface or subsurface 
strata, surface waters (including navigable waters, oceans waters, streams, 
ponds, drainage basins and wetlands), groundwaters, drinking water supply, 
stream sediments, ambient air (including indoor air), plant and animal life 
and any other environmental medium or natural resource.

          (b)  With respect to the real estate owned (including other real 
estate owned) or leased by Shipman or the Bank (the "Shipman Premises"), to 
the Knowledge of Shipman and the Bank:  (i) no part of the Shipman Premises 
has been used for the generation, manufacture, handling, storage or disposal 
of Hazardous Substances (as defined below); (ii) except as disclosed in 
Schedule 4.21, the Shipman Premises do not contain, and have never contained, 
an underground storage tank; and (iii) the Shipman Premises do not contain 
and are not contaminated by any material quantity of a Hazardous Substance 
from any source. For purposes of this Agreement, "Hazardous Substance" has 
the meaning set forth in Section 9601 of the Comprehensive Environmental 
Response Compensation and Liability Act of 1980, 42 U.S.C.A., Section 9601 ET 
SEQ., and also includes any substance now or hereafter regulated by or 
subject to any Environmental Laws (as defined below) and any other pollutant, 
contaminant or waste, including, petroleum, asbestos, fiberglass, radon and 
polychlorinated biphenyls.  For purposes of this Agreement, "Environmental 
Laws" means all laws (civil or common), ordinances, rules, regulations, 
guidelines and orders that: (w) regulate air, water, soil and solid waste 
management, including the generation, release, containment, storage, 
handling, transportation, disposition or management of any Hazardous 
Substance; (x) regulate or prescribe requirements for air, water or soil 
quality; (y) are intended to protect public health or the environment; or (z) 
establish liability for the investigation, removal or cleanup of, or damage

     SECTION 4.22   REGULATORY FILINGS.  Each of Shipman and the Bank has 
filed in a timely manner all required filings with all bank Regulatory 
Authorities, including the Federal Reserve, the Federal Deposit Insurance 
Corporation and the Commissioner.  To the Knowledge of Shipman and the Bank, 
all such filings were accurate and complete in all material respects as of 
the dates of the filings, and no such filing has made any untrue statement of 
a material fact or omitted to state a material fact necessary in order to 
make the statements made, in light of the circumstances under which they were 
made, not misleading.

     SECTION 4.23   FIDUCIARY POWERS.  The Bank has properly administered all 
accounts for which it acts as fiduciary, including accounts for which it 
serves as trustee, agent, custodian or investment advisor, in accordance with 
the terms of the governing documents and applicable state and federal law and 
regulations and common law.  None of the Bank or any of its directors, 
officers or employees has committed any breach of trust with respect to any 
such fiduciary account, and the accountings for each such fiduciary account 
are true and correct in all material respects and accurately reflect the 
assets of such fiduciary account.

     SECTION 4.24   DISCLOSURE. No representation or warranty of Shipman in 
this Agreement omits to state a material fact necessary to make the 
statements herein or therein, in light of the circumstances in which they 
were made, not misleading.  No notice given pursuant to Section 6.5 will 
contain any untrue statement or omit to state a material fact necessary to 
make the statements therein or in this Agreement, in light of the 
circumstances in which they were made, not misleading.  There is no fact 
known to Shipman that has specific application to either Shipman or the Bank 
(other than general economic or industry conditions) and that materially 
adversely affects or, as far as Shipman can reasonably foresee, materially 
threatens, the assets, business, prospects, financial condition, or results 
of operations of Shipman or the Bank that has not been set forth in this 
Agreement.

incurred any obligation or liability, contingent or otherwise, for brokerage 
or finders' fees or agents' commissions or other similar payment in 
connection with this Agreement.

     SECTION 4.26   APPROVAL DELAYS.  To the Knowledge of Shipman or the 
Bank, there is no reason why the granting of any of the regulatory approvals 
referred to in Section 7.2 would be denied or unduly delayed.

     SECTION 5.4    NO CONFLICT.  Neither the execution nor delivery of this 
Agreement nor the consummation or performance of any of the Contemplated 
Transactions will, directly or indirectly (with or without notice of lapse of

provision of the certificate or articles of incorporation, and the bylaws, of 
CNB and Acquisition Corp, or any resolution adopted by the board of directors 
or stockholders of either of them; (b) contravene, conflict with, or result 
in a violation of, or give any Regulatory Authority or other Person the right 
to challenge any of the Contemplated Transactions or to exercise any remedy 
or obtain any relief under, any Legal Requirement or any Order to which CNB 
or Acquisition Corp, or any of the assets owned or used by CNB or Acquisition 
Corp, may be subject, other than any of the foregoing that would be satisfied 
by compliance with the provisions of the BHCA, the Illinois Code and the 
Illinois Banking Act; (c) contravene, conflict with, or result in a violation

connection with the execution and delivery of this Agreement or the 
consummation or performance of any of the Contemplated Transactions.

     SECTION 5.5    CNB CAPITALIZATION. The authorized capital stock of CNB 
consists exclusively of 210,000 shares of capital stock, $1.00 par value per 
share, 186,498 of which shares are, and will be immediately prior to the 
Closing, duly issued and outstanding, fully paid and non-assessable, and 
13,502 of which shares are, and will be immediately prior to the Closing,

shares of capital stock of CNB; (b) there are no outstanding securities of 
CNB which are convertible into or exchangeable for any shares of CNB's

Legal Requirement.  Except as otherwise disclosed in this Agreement, CNB does 
not own or have any Contract to acquire, any equity securities or other 
securities of any Person or any direct or indirect equity or ownership 
interest in any other business.

     SECTION 5.6    FINANCIAL STATEMENTS AND REPORTS.  True, correct and 
complete copies of the following financial statements and reports are 
attached as Schedule 5.6 (the "CNB Financial Statements"):

          (a)  for each of the years ended December 31, 1993, 1994, 1995 and 
1996, the audited Consolidated Balance Sheets and the related Statements of 
Income, Statements of Changes in Stockholders' Equity and Statements of Cash 
Flows of CNB; and

          (b)  for the nine months ended September 30, 1997, the unaudited 
Consolidated Balance Sheet and the related Statement of Income, Statement of 
Changes in Stockholders' Equity and Statement of Cash Flows of CNB.

                                        A-29
<PAGE>

     The audited CNB Financial Statements described in clause (a) have been 
prepared in accordance with generally accepted accounting principles 
consistently applied.  Taken together, the CNB Financial Statements fairly 
and accurately present in all material respects the respective financial 
position, assets, liabilities and results of operations of CNB and its 
Subsidiaries as at the respective dates of and for the periods referred to in 
the CNB Financial Statements.

     SECTION 5.7    BOOKS AND RECORDS.  The books of account, minute books, 
stock record books and other records of CNB and its Subsidiaries are complete 
and correct in all material respects, and have been maintained in accordance 
with sound business practices and all applicable Legal Requirements, 
including the maintenance of any adequate system of internal controls.  The 
minute books of CNB and its Subsidiaries contain accurate and complete 
records in all material respects of all meetings held of, and corporate 
action taken by, the stockholders, the Board of Directors, and committees of 
the Board of Directors of CNB and its Subsidiaries, respectively, and no 
meeting of any such stockholders, Board of Directors or committee has been 
held for which minutes have not been prepared and are not contained in such 
minute books.  At the Closing, all of those books and records will be in the 
possession of CNB or its Subsidiaries.

     SECTION 5.8    TITLE TO PROPERTIES.  Each of CNB and its Subsidiaries 
has good and marketable title to all assets and properties, whether real or 
personal, tangible or intangible, which it purports to own subject to no 
liens, mortgages, security interests, encumbrances or charges of any kind 
except: (a) as noted in the most recent CNB Financial Statement or on 
Schedule 5.8; (b) statutory liens for Taxes not yet delinquent or being 
contested in good faith by appropriate Proceedings and for which appropriate 
reserves have been established and reflected on the Financial Statements; (c) 
pledges or liens required to be granted in connection with the acceptance of 
government deposits, granted in connection with repurchase or reverse 
repurchase agreements or otherwise incurred in the Ordinary Course of 
Business; and (d) minor defects and irregularities in title and encumbrances 
which do not materially impair the use thereof for the purposes for which 
they are held and which would not reasonably be expected to have a material 
adverse effect on the consolidated financial condition, assets or business of 
CNB.  Each of CNB and its Subsidiaries as lessee has the right under valid 
and existing leases to occupy, use, possess and control any and all of the 
respective property leased by it.  All buildings and structures owned by each 
of CNB and its Subsidiaries lie wholly within the boundaries of the real 
property owned or validly leased by it and do not encroach upon the property 
of, or otherwise conflict with the property rights of, any other Person.

     SECTION 5.9    CONDITION AND SUFFICIENCY OF ASSETS.  The buildings, 
structures and equipment of CNB and its Subsidiaries are structurally sound, 
are in good operating condition and repair, and are adequate for the uses to 
which they are being put, and none of such buildings, structures or equipment 
is in need of maintenance or repairs except for ordinary, routine maintenance 
and repairs that are not material in nature or cost.  To the Knowledge of CNB 
and its Subsidiaries, the buildings, structures and equipment of CNB and its 
Subsidiaries are in compliance with the ADA and the regulations promulgated 
thereunder at the effective date of each part of the ADA or the regulations, 
and are sufficient for the continued conduct of the business of CNB and its 
Subsidiaries after the Closing in substantially the same manner as conducted 
prior to the Closing.

                                        A-30
<PAGE>

     SECTION 5.10   LOANS; LOAN LOSS RESERVE.  All loans and loan commitments 
extended by the banking Subsidiaries of CNB and any extensions, renewals or 
continuations of such loans and loan commitments (the "CNB Loans") were made 
in accordance with customary lending standards of such Subsidiaries in the 
Ordinary Course of Business.  The CNB Loans are evidenced by appropriate and 
sufficient documentation and constitute valid and binding obligations to the 
banking Subsidiaries of CNB enforceable in accordance with their terms.  All 
such CNB Loans are, and at the Closing will be, free and clear of any 
encumbrance or other charge and the banking Subsidiaries of CNB have 
complied, and at the Closing will have complied, in all material respects 
with all laws and regulations relating to such CNB Loans.  The reserves for 
possible loan and lease losses shown on the latest Call Reports of the 
banking Subsidiaries of CNB are and will be on the Closing Date adequate in 
all material respects under the standards applied by applicable Regulatory 
Authorities and based upon generally accepted accounting practices applicable 
to financial institutions to provide for possible or specific losses, net of 
recoveries relating to loans previously charged off, and contain and will 
contain an additional amount of unallocated reserves for unanticipated future 
losses at an adequate level.  To the Knowledge of CNB and its Subsidiaries, 
none of the CNB Loans is subject to any material offset or claim of offset, 
and the aggregate loan balances in excess of CNB's consolidated reserve for 
loan and lease losses are, based on past loan loss experience, collectible in 
accordance with their terms and all uncollectible loans have been charged 
off.  Notwithstanding anything in this Section to the contrary, all of the 
representations and warranties made in this Section are expressly subject to 
the exceptions set forth in Schedule 5.10.

     SECTION 5.11   UNDISCLOSED LIABILITIES; ADVERSE CHANGES.  CNB does not 
have any liabilities or obligations of any nature (whether known or unknown 
and whether absolute, accrued, contingent, or otherwise) except for 
liabilities or obligations reflected or reserved against in the CNB Financial 
Statements or current liabilities incurred in the Ordinary Course of Business 
since the respective dates thereof.  Since the date of the latest CNB 
Financial Statement, there has not been any material adverse change in the 
business, operations, properties,  assets, or condition of CNB or its 
Subsidiaries, and no event has occurred or circumstance exists that may 
result in such a material adverse change.

     SECTION 5.12   TAXES.  Each of CNB and its Subsidiaries has duly filed 
or will duly file all Tax Returns required to be filed by it for all periods 
prior to the Closing Date, and each such Tax Return is complete and accurate 
in all material respects.  Each of CNB and its Subsidiaries has paid, or made 
adequate provision for the payment of, all Taxes (whether or not reflected in 
Tax Returns as filed or to be filed) due and payable by CNB or its 
Subsidiaries, or claimed to be due and payable by any Regulatory Authority, 
and is not delinquent in the payment of any Tax, except such Taxes as are 
being contested in good faith and as to which adequate reserves have been 
provided.  There is no claim or assessment pending or Threatened against  CNB 
or any of its Subsidiaries for Taxes owed by any of them.  No audit, 
examination or investigation related to Taxes paid or payable by CNB or its 
Subsidiaries is presently being conducted or Threatened by any Regulatory 
Authority.

     SECTION 5.13   COMPLIANCE WITH ERISA.  All employee benefit plans (as 
defined in Section 3(3) of ERISA) established or maintained by CNB or its 
Subsidiaries or to which CNB

                                        A-31
<PAGE>

or its Subsidiaries contribute, are in compliance in all material respects 
with all applicable requirements of ERISA, and are in compliance in all 
material respects with all applicable requirements (including qualification 
and non-discrimination requirements in effect as of the Closing) of the Code 
for obtaining the tax benefits the Code thereupon permits with respect to 
such employee benefit plans.  For purposes of this Section, non-compliance 
with the Code and ERISA is material if such non-compliance would reasonably 
be expected to have a material adverse effect on the consolidated financial 
condition, assets or business of CNB.  No such employee benefit plan has, or 
as of the Closing will have, any amount of unfunded benefit liabilities (as 
defined in Section 4001(a)(18) of ERISA) for which CNB or any of its 
Subsidiaries would be liable to any Person under Title IV of ERISA if any 
such employee benefit plan were terminated as of the Closing, which amounts 
would be material to CNB and its Subsidiaries on a consolidated basis.  Such 
employee benefit plans are funded in accordance with Section 412 of the Code 
(if applicable).  There would be no obligations which would be material to 
CNB and its Subsidiaries on a consolidated basis under Title IV of ERISA 
relating to any such employee benefit plan that is a multi-employer plan if 
any such plan were terminated or if CNB or any of its Subsidiaries withdrew 
from any such plan as of the Closing.

     SECTION 5.14   COMPLIANCE WITH LEGAL REQUIREMENTS.  Except as set forth 
in Schedule 5.14, each of CNB and its Subsidiaries is, and at all times since 
January 1, 1996, has been, in full compliance with each Legal Requirement 
that is or was applicable to it or to the conduct or operation of its 
business or the ownership or use of any of its assets where the failure to be 
in such full compliance would reasonably be expected to have a material 
adverse effect on the consolidated financial condition of CNB and its 
Subsidiaries.  No event has occurred or circumstance exists that (with or 
without notice or lapse of time): (a) may constitute or result in a violation 
by CNB or any of its Subsidiaries of, or a failure on the part of CNB or any 
of its Subsidiaries to comply with, any Legal Requirement; or (b) may give 
rise to any obligation on the part of CNB or any of its Subsidiaries to 
undertake, or to bear all or any portion of the cost of, any remedial action 
of any nature.  Except as set forth on Schedule 5.14, none of CNB or any of 
its Subsidiaries has received, at any time since January 1, 1996, any notice 
or other communication (whether oral or written) from any Regulatory 
Authority or any other Person regarding:  (x) any actual, alleged, possible, 
or potential violation of, or failure to comply with, any Legal Requirement; 
or (y) any actual, alleged, possible, or potential obligation on the part of 
CNB or any of its Subsidiaries to undertake, or to bear all or any portion of 
the cost of, any remedial action of any nature.

     SECTION 5.15   LEGAL PROCEEDINGS; ORDERS.  Schedule 5.15 is a true and 
correct list of all Proceedings and Orders pending, entered into or, to the 
Knowledge of CNB and its Subsidiaries, Threatened against or affecting CNB or 
its Subsidiaries or any of their respective assets or business, or the 
Contemplated Transactions, since January 1, 1996.  Except to the extent 
indicated in Schedule 5.15, no such pending or Threatened Proceeding or Order 
could, alone or in the aggregate, adversely affect the business, properties, 
assets, condition, prospects or rights of CNB and its Subsidiaries, taken as 
a whole, and there is no fact which would provide a basis for any Proceeding 
or Order which could have such an effect.  To the Knowledge of CNB and its 
Subsidiaries, no officer, director, agent, or employee of CNB or its 
Subsidiaries is subject to any Order that prohibits such officer, director, 
agent, or employee from engaging in or continuing any

                                        A-32
<PAGE>

conduct, activity or practice relating to the business of CNB or its 
Subsidiaries.  None of CNB or any of its Subsidiaries has received, at any 
time since January 1, 1996, any notice or other communication (whether oral 
or written) from any Regulatory Authority or any other Person regarding any 
actual, alleged, possible, or potential violation of, or failure to comply 
with, any Legal Requirement to which CNB or any of its Subsidiaries, or any 
of the assets owned or used by any them, is or has been subject.

     SECTION 5.16   NO DEFAULTS.  Each Contract to which CNB or any of its 
Subsidiaries is a party or to which any of the assets owned or used by either 
of them is or was bound, and which is material to CNB or its Subsidiaries on 
a consolidated basis (a "CNB Material Contract") is in full force and effect 
and is valid and enforceable in accordance with its terms.  Each of CNB and 
its Subsidiaries is, and at all times since January 1, 1996, has been, in 
full compliance with all applicable terms and requirements of each CNB 
Material Contract.  Each other Person that has or had any obligation or 
liability under any CNB Material Contract is, and at all times since January 
1, 1996, has been, in full compliance with all applicable terms and 
requirements of such CNB Material Contract.  No event has occurred or 
circumstance exists that (with or without notice or lapse of time) may 
contravene, conflict with, or result in a violation or breach of, or give 
CNB, its Subsidiaries or other Person the right to declare a default or 
exercise any remedy under, or to accelerate the maturity or performance of, 
or to cancel, terminate, or modify, any CNB Material Contract.  Neither CNB 
nor any of its Subsidiaries has given to or received from any other Person, 
at any time since January 1, 1996, any notice or other communication (whether 
oral or written) regarding any actual, alleged, possible, or potential 
violation or breach of, or default under, any CNB Material Contract.  Other 
than in the Ordinary Course of Business in connection with workouts and 
restructured loans, there are no renegotiations of, attempts to renegotiate, 
or outstanding rights to renegotiate any material amounts paid or payable to 
CNB or its Subsidiaries under any current or completed CNB Material Contract 
with any Person and no such Person has made written demand for such 
renegotiation.

     SECTION 5.17   COMPLIANCE WITH ENVIRONMENTAL LAWS.  (a) Except as set 
forth on Schedule 5.17, there are no actions, suits, investigations, 
liabilities, inquiries, Proceedings or Orders involving CNB or any of its 
Subsidiaries or any of their respective assets that are pending or, to the 
Knowledge of CNB and its Subsidiaries, Threatened, nor to the Knowledge of 
CNB and its Subsidiaries is there any factual basis for any of the foregoing, 
as a result of any asserted failure of CNB or any of its Subsidiaries, or any 
predecessor thereof, to comply (or the assertion of liability even if in 
compliance) with any Legal Requirements designed to minimize, prevent, punish 
or remedy the consequences of actions that damage or threaten the soil, land 
surface or subsurface strata, surface waters (including navigable waters, 
oceans waters, streams, ponds, drainage basins and wetlands), groundwaters, 
drinking water supply, stream sediments, ambient air (including indoor air), 
plant and animal life and any other environmental medium or natural resource. 

          (b)  With respect to the real estate owned (including other real 
estate owned) or leased by CNB or any of its Subsidiaries (the "CNB 
Premises"), to the Knowledge of CNB and its Subsidiaries:  (i) no part of the 
CNB Premises has been used for the generation, manufacture, handling, storage 
or disposal of Hazardous Substances; (ii) except as disclosed in Schedule 5.17,

                                        A-33
<PAGE>

the Acquiror Premises do not contain, and have never contained, an 
underground storage tank; and (iii) the CNB Premises do not contain and are 
not contaminated by any material quantity of a Hazardous Substance from any 
source.

     SECTION 5.18   REGULATORY FILINGS.  Each of CNB and its Subsidiaries has 
filed in a timely manner all required filings with all bank Regulatory 
Authorities, including the Federal Reserve, the Federal Deposit Insurance 
Corporation, the Office of the Comptroller of the Currency and the 
Commissioner. To the Knowledge of CNB, all such filings were accurate and 
complete in all material respects as of the dates of the filings, and no such 
filing has made any untrue statement of a material fact or omitted to state a 
material fact necessary in order to make the statements made, in light of the 
circumstances under which they were made, not misleading.

     SECTION 5.19   DISCLOSURE. No representation or warranty of CNB in this 
Agreement omits to state a material fact necessary to make the statements 
herein or therein, in light of the circumstances in which they were made, not 
misleading.  No notice given pursuant to Section 7.4 will contain any untrue 
statement or omit to state a material fact necessary to make the statements 
therein or in this Agreement, in light of the circumstances in which they 
were made, not misleading.  There is no fact known to CNB that has specific 
application to CNB or any of its Subsidiaries (other than general economic or 
industry conditions) and that materially adversely affects or, as far as CNB 
can reasonably foresee, materially threatens, the consolidated assets, 
business, prospects, financial condition, or results of operations of CNB 
that has not been set forth in this Agreement.

     SECTION 5.20   BROKERAGE COMMISSIONS.  None of CNB or any of its agents 
has incurred any obligation or liability, contingent or otherwise, for 
brokerage or finders' fees or agents' commissions or other similar payment in 
connection with this Agreement.

     SECTION 5.21   APPROVAL DELAYS.  To the Knowledge of CNB, there is no 
reason why the granting of any of the regulatory approvals referred to in 
Section 7.2 would be denied or unduly delayed.

                                     ARTICLE 6
                                          
                                SHIPMAN'S COVENANTS

     SECTION 6.1    ACCESS AND INVESTIGATION.  CNB and its Representatives 
shall, at all times during normal business hours and with reasonable advance 
notice prior to the Closing Date, have full and continuing access to the 
facilities, operations, records and properties of the Bank in accordance with 
the provisions of this Section. CNB and its Representatives may, prior to the 
Closing Date, make or cause to be made such reasonable investigation of the 
operations, records and properties (including an audit of the books and 
records of Shipman to be performed at Shipman's expense by independent 
certified public accountants selected by CNB and subject to the reasonable 
approval of Shipman, and environmental review and testing of real property to 
be performed at Shipman's expense by independent environmental consultants 
selected by CNB and subject to the reasonable approval of Shipman) of each of 
Shipman and the Bank and of its

                                        A-34
<PAGE>

respective financial and legal condition as CNB shall deem necessary or 
advisable to familiarize itself with such records, properties and other 
matters; provided, that such access or investigation shall not interfere 
unnecessarily with the normal operations of the Bank.  Upon request, each of 
Shipman and the Bank will furnish CNB or its Representatives, attorneys' 
responses to auditors' requests for information regarding Shipman or the 
Bank, as the case may be, and such financial and operating data and other 
information reasonably requested by CNB (provided with respect to attorneys, 
such disclosure would not result in the waiver by Shipman or the Bank of any 
claim of attorney-client privilege), and will permit CNB or its 
Representatives to discuss such information directly with any individual or 
firm performing auditing or accounting functions for Shipman or the Bank, and 
such auditors and accountants shall be directed to furnish copies of any 
reports or financial information as developed to CNB or its Representatives.  
Shipman shall, and shall cause the Bank to, give CNB prior notice of each 
meeting of its board of directors and any committees thereof, including the 
Bank's loan committee, and CNB shall be invited to have one of its 
Representatives in attendance at each such meeting as an observer, except for 
any such meeting if and to the extent that compliance with, or any amendment 
to, this Agreement or any Acquisition Transaction (as defined below) is 
discussed.  No investigation by CNB or attendance by a CNB's Representative 
at any board or committee meeting shall affect the representations and 
warranties made by Shipman in this Agreement.  This Section shall not require 
the disclosure of any information the disclosure of which to CNB would be 
prohibited by law.

     SECTION 6.2    OPERATIONS OF SHIPMAN AND THE BANK.  Except as otherwise 
approved by CNB in writing, between the date of this Agreement and the 
Closing Date, Shipman will, and will cause the Bank, to 

          (a)  conduct the business of Shipman and the Bank only in the 
Ordinary Course of Business;

          (b)  use its Best Efforts to preserve intact the current business 
organization of Shipman and the Bank, keep available the services of the 
current officers, employees and agents of Shipman and the Bank, and maintain 
the relations and good will with suppliers, customers, landlords, creditors, 
employees, agents and others having business relationships with Shipman or 
the Bank;

          (c)  confer with CNB concerning operational matters of a material 
nature; 

          (d)  enter into loan transactions only in accordance with sound 
credit practices and only on terms and conditions which are not materially 
more favorable than those available to the borrower from competitive sources 
in arm's-length transactions;

          (e)  enter into no new credit or new lending relationship in excess 
of $50,000 to any Person and such Person's Affiliate, except for:  (i) loans 
of no greater than $100,000 secured by first mortgages on owner-occupied 
residential real estate where the loan to value ratio is 80% or less, or (ii) 
with the prior written consent of CNB which consent shall be conclusively 
presumed if CNB has not responded to a written request from Shipman or the 
Bank for such consent (when such written request is accompanied by all 
material information necessary to make

                                        A-35
<PAGE>

a credit decision) by the same hour of the next day which is a Business Day 
for both Shipman, the Bank and CNB;

          (f)  enter into no new financing leases, or amend or modify in any 
material respect the terms of any current financing lease, without the prior 
written consent of CNB which consent shall be conclusively presumed if CNB 
has not responded to a written request from Shipman or the Bank for such 
consent (when such written request is accompanied by all material information 
necessary to make a credit decision) by the same hour of the next day which 
is a Business Day for both Shipman, the Bank and CNB;

          (g)  other than incident to a reasonable loan restructuring, extend 
no additional credit to any Person or such Person's Affiliate if such Person 
or such Affiliate is the obligor under any indebtedness to the Bank which 
constitutes a non-performing loan or against any part of such indebtedness 
the Bank has established loss reserves or any part of which has been 
charged-off by the Bank, except with the prior written consent of CNB;

          (h)  consistent with past practice, maintain a reserve for possible 
loan and lease losses which is adequate under the standards applied by

the financial condition and results of operations for the dates and periods 
presented.  The Shipman Subsequent Financial Statements will not include any

made as of the time of occurrence or discovery of such fact or condition.  
Should any such fact or condition require any change in the Schedules if such 
Schedules were dated the date of the occurrence or discovery of any such fact

Schedules specifying such change.  During the same period, Shipman will 
promptly notify CNB of the occurrence of any Breach of any covenant of

requested action that is irrevocable until immediately prior to the Closing

Shipman or its Representatives to discuss such information directly with any 
individual or firm performing auditing or accounting functions for CNB or its 
Subsidiaries, and such auditors and accountants shall be directed to furnish

meeting if and to the extent that compliance with, or any amendment to, this 
Agreement is discussed.  No investigation by Shipman or attendance by Mr.

provide an opportunity to comment thereon, and thereafter shall promptly 
advise Shipman and its counsel of any material communication received by CNB 
or its counsel from the SEC with respect to the Registration Statement.

          (b)  CNB agrees that none of the information concerning CNB or its 
Subsidiaries which is included in the Registration Statement or Proxy 
Statement-Prospectus and any other documents to be filed with any Regulatory 
Authority in connection with the Contemplated Transactions will, at the 
respective times such documents are filed and, in the case of the 
Registration Statement, when it becomes effective and, with respect to the 
Proxy Statement-Prospectus, when mailed, be false or misleading with respect 
to any material fact, or omit to state any material fact necessary in order 
to make the statements therein not misleading or, in the case of the Proxy 
Statement-Prospectus, or any amendment thereof or supplement thereto, at the 
time of the Special Meeting, be false or misleading with respect to any 
material fact, or omit to state any material fact necessary to correct any 
statement in any earlier communication with respect to the solicitation of 
any proxy for the meeting in connection with which the Proxy 
Statement-Prospectus shall be mailed.  Notwithstanding the foregoing, CNB 
shall have no responsibility for the truth or accuracy of any information 
with respect to Shipman or the Bank contained in the Registration Statement 
or the Proxy Statement-Prospectus.

     SECTION 7.6    CNB SUBSEQUENT FINANCIAL STATEMENTS.  As soon as

practices and shall fairly present the financial condition and results of 
operations for the dates and periods presented.  The CNB Subsequent Financial 
Statements will not include any material assets or omit to state any material 
liabilities, absolute or contingent, or other facts, which inclusion or 
omission would render such Financial Statements misleading in any material 
respect.

     SECTION 7.7    INDEMNIFICATION OF SHIPMAN AFFILIATES.  (a) From and 
after the Effective Time, CNB agrees to indemnify and hold harmless each 
person who, as of the date immediately prior to the Closing, served as a 
director or officer of Shipman or the Bank and who has delivered to CNB an 
Indemnification Certificate that is true and accurate (an "Indemnified 
Person") from and against all damages, liabilities, judgments and claims (and 
related expenses, including reasonable attorneys' fees and amounts paid in 
settlement) based upon or arising from his or her capacity as an officer or 
director of Shipman or the Bank, to the full extent as indemnification is 
required under the articles of incorporation or bylaws of Shipman, as the 
same are in effect on the date of this Agreement, PROVIDED, HOWEVER, that 
such indemnification shall not cover any claim made by a shareholder of 
Shipman that is related to the Contemplated Transactions.  The rights granted 
by this Section to the Indemnified Persons shall be contractual rights 
inuring to the benefit of all Indemnified Persons and shall survive this 
Agreement and any merger, consolidation or reorganization of CNB.

          (b)  CNB further agrees to indemnify and hold harmless Shipman, 
each of its directors and officers and each person, if any, who controls 
Shipman or the Bank within the meaning of the Securities Act (an "Indemnified 
Affiliate"), against any losses, claims, damages or liabilities, joint, 
several or solitary, to which they or any of them may become subject under 
the Securities Act or otherwise, insofar as such losses, claims, damages or 
liabilities (or actions in respect thereof) arise out of or are based upon 
any untrue statement or alleged untrue statement of a material fact contained 
in the Registration Statement or arising out of or based upon the omission or 
alleged omission to state therein a material fact required to be stated 
therein or necessary to make the statements therein not misleading in any 
material respect, and will reimburse each such person for any legal or other 
expenses reasonably incurred by such person in connection with investigating 
or defending any such action or claim, PROVIDED, HOWEVER, that CNB shall not 
be liable in any such case to the extent that any such loss, claim, damage or 
liability (or action in respect thereof) arises out of or is based upon any 
untrue statement or alleged untrue statement of a material fact contained in 
the Registration Statement or arising out of or based upon the omission or 
alleged omission to state therein a material fact required to be stated 
therein or necessary to make the statements therein not misleading in any 
material respect in reliance upon and in conformity with information 
furnished, or failed to be furnished, to CNB by Shipman or the Bank for use 
in the Registration Statement.

          (c)  Promptly after receipt by an Indemnified Person or Affiliate 
of notice of the commencement of any Proceeding for which such Indemnified 
Person or Affiliate intends to make a claim under this Section against CNB 
for indemnification (a "Claim"), such Indemnified Person or Affiliate shall 
promptly give written notice to CNB of the Claim.  If CNB confirms in writing 
to such Indemnified Person or Affiliate its agreement to provide 
indemnification of such Claim, then CNB shall have the right and obligation 
to conduct and control, through counsel of

                                        A-43
<PAGE>

its choosing, the defense, compromise or settlement of any such Claim.  In 
the absence of such written confirmation from CNB, the Indemnified Person or 
Affiliate against whom the Claim is made shall have the right to conduct and 
control, through counsel of its choosing, the defense, compromise or 
settlement of such Claim without prejudice to the Indemnified Person's rights 
against CNB for indemnification.

     SECTION 7.8    ADVICE OF CHANGES.  Between the date of this Agreement 
and the Closing Date, CNB will promptly notify Shipman in writing if CNB 
becomes aware of any fact or condition that causes or constitutes a Breach of 
any of CNB's representations and warranties as of the date of this Agreement, 
or if CNB becomes aware of the occurrence after the date of this Agreement of 
any fact or condition that would (except as expressly contemplated by this 
Agreement) cause or constitute a Breach of any such representation or 
warranty had such representation or warranty been made as of the time of 
occurrence or discovery of such fact or condition.  During the same period, 
CNB will promptly notify Shipman of the occurrence of any Breach of any 
covenant of CNB in this Article or of the occurrence of any event that may 
make the satisfaction of the conditions in Article 9 impossible or unlikely.

     SECTION 7.9    BEST EFFORTS.  CNB agrees to use its Best Efforts in good 
faith to satisfy the various covenants and conditions to Closing in this 
Article and Article 9, respectively, and to consummate the transactions 
contemplated hereby as promptly as possible.  CNB will not intentionally take 
or intentionally permit to be taken any action that would be in breach of the 
terms or provisions of this Agreement or that would cause any of the 
representations or warranties contained herein to be or become untrue.

     SECTION 7.10   INCREASE IN AUTHORIZED STOCK.  CNB agrees to recommend to 
its stockholders at its annual meeting to be held on March 17, 1998, a 
proposal to amend CNB's certificate of incorporation to increase the number 
of shares of the authorized CNB Common Stock to the maximum number of shares 
necessary to issue shares of CNB Common Stock for all of the shares of 
Shipman Common Stock that are issued and outstanding immediately prior to the 
Effective Time (the "CNB Amendment").  CNB further agrees to use its Best 
Efforts to obtain stockholder approval of such amendment.

     SECTION 7.11   DIRECTOR NOMINEES.  CNB agrees to take such action after 
the Effective Time as is necessary to add Mr. Frank as a director of CNB.  
Shipman acknowledges that CNB intends immediately after the Effective Time to 
replace all of the Bank's directors, but CNB agrees that the new directors of 
the Bank it causes to be elected shall consist of not less than two (2) nor 
more than four (4) of the individuals serving as directors of the Bank as of 
the date of this Agreement.

                                    TERMINATION

     SECTION 10.1   REASONS FOR TERMINATION AND ABANDONMENT.  This Agreement 
may, by prompt written notice given to the other parties prior to or at the 
Closing, be terminated:

          (a)  by mutual consent of the Boards of Directors of Shipman, CNB and
Acquisition Corp;

          (b)  by either CNB or Shipman if a material Breach of any provision 
of this Agreement has been committed by the other party and such Breach has 
not been waived, PROVIDED, HOWEVER, that CNB shall not be permitted to 
terminate this Agreement as a result of any Breach by Acquisition Corp;

          (c)  by CNB if any of the conditions in Article 8 has not been 
satisfied as of the Closing Date or if satisfaction of such a condition is or 
becomes impossible (other than through the failure of CNB or Acquisition Corp 
to comply with its respective obligations under this Agreement) and CNB has 
not waived such condition on or before the Closing Date;

                                        A-48
<PAGE>

          (d)  by Shipman, if any of the conditions in Article 9 has not been 
satisfied as of the Closing Date or if satisfaction of such a condition is or 
becomes impossible (other than through the failure of Shipman to comply with 
its obligations under this Agreement) and Shipman has not waived such 
condition on or before the Closing Date; or

          (e)  by either CNB or Shipman if the Closing has not occurred 
(other than through the failure of any party seeking to terminate this 
Agreement to comply fully with its obligations under this Agreement) on or 
before the date which is ten months after the date of this Agreement or such 
later date as the parties may agree upon.

     SECTION 10.2   EFFECT OF TERMINATION.  Each party's right of termination 
under Section 10.1 is in addition to any other rights it may have under this 
Agreement or otherwise, and the exercise of a right of termination will not 
be an election of remedies.  If this Agreement is terminated pursuant to 
Section 10.1, all further obligations of the parties under this Agreement 
(except those set forth in Section 10.3) will terminate, PROVIDED, HOWEVER, 
that if this Agreement is terminated by a party because of the Breach of the 
Agreement by the other party or because one or more of the conditions to the 
terminating party's obligations under this Agreement is not satisfied as a 
result of the other party's failure to comply with its obligations under this 
Agreement, the terminating party's right to pursue all legal remedies will 
survive such termination unimpaired.

     SECTION 10.3   PAYMENT TO CNB.  In addition to any other damages to 
which CNB may be entitled, if this Agreement is terminated because Shipman 
breaches its obligations under this Agreement, unless such breach or failure 
is a result of the failure by CNB or Acquisition Corp to perform and comply 
in all material respects with any of its material obligations under this 
Agreement which are to be performed or complied with by it prior to or on the 
date required hereunder, and within 24 months after the termination of this 
Agreement Shipman enters into an agreement with any party other than CNB 
providing for the acquisition of control of Shipman or the Bank by such other 
party and the transaction contemplated by such agreement is consummated at 
any time thereafter, then Shipman shall pay to CNB, upon its written demand, 
the sum of $200,000, PROVIDED, HOWEVER, that the provisions of this Section 
shall in no way limit CNB's rights against any such third party.  For 
purposes of this Section, the phrase "control of Shipman or the Bank" means 
the acquisition by any such third party of:  (a) legal or beneficial 
ownership (as defined by Rule 13d-3 promulgated under the Securities Exchange 
Act of 1934, as amended) of greater than 50% of the then issued and 
outstanding voting stock of Shipman or the Bank through any transaction to 
which Shipman, the Bank or any Affiliate of Shipman or the Bank is a party; 
or (b) all or substantially all of the assets of Shipman or the Bank.

     SECTION 10.4   PAYMENT TO SHIPMAN.  In addition to any other damages to 
which Shipman may be entitled, if this Agreement is terminated because CNB 
breaches its obligations under this Agreement, unless such breach or failure 
is a result of the failure by Shipman to perform and comply in all material 
respects with any of its material obligations under this Agreement which are 
to be performed or complied with by it prior to or on the date required 
hereunder, then CNB shall pay to Shipman, upon its written demand, an amount 
equal to the sum of all expenses incurred in connection with the audit of 
Shipman's books and records and the

                                        A-49

environmental review and test of Shipman's real property pursuant to Section 
6.1 (collectively, the "Additional Transaction Expenses"). 

                                          
                                     ARTICLE 11
                                   MISCELLANEOUS

     SECTION 11.1   GOVERNING LAW.  All questions concerning the 
construction, validity and interpretation of this Agreement, and the 
performance of the obligations imposed by this Agreement shall be governed by 
the internal laws of the State of Illinois applicable to Contracts made and 
wholly to be performed in such state without regard to conflicts of laws.

     SECTION 11.2   ASSIGNMENTS, SUCCESSORS AND NO THIRD PARTY RIGHTS.  None 
of the parties to this Agreement may assign any of its rights under this 
Agreement without the prior consent of the other parties, except that either 
or both of CNB and Acquisition Corp may assign any of its respective rights 
(but not its obligations) under this Agreement to any Subsidiary of CNB.  
Subject to the preceding sentence, this Agreement will apply to, be binding 
in all respects upon, and inure to the benefit of the successors and 
permitted assigns of the parties.  Nothing expressed or referred to in this 
Agreement will be construed to give any Person other than the parties to this 
Agreement any legal or equitable right, remedy or claim under or with respect 
to this Agreement or any provision of this Agreement.  This Agreement and all 
of its provisions and conditions are for the sole and exclusive benefit of 
the parties to this Agreement and their successors and assigns.

     SECTION 11.3   WAIVER. The rights and remedies of the parties to this 
Agreement are cumulative and not alternative.  Neither the failure nor any 
delay by any party in exercising any right, power or privilege under this 
Agreement or the documents referred to in this Agreement will operate as a 
waiver of such right, power or privilege, and no single or partial exercise 
of any such right, power or privilege will preclude any other or further 
exercise of such right, power or privilege or the exercise of any other 
right, power or privilege.  To the maximum extent permitted by applicable 
law:  (a) no claim or right arising out of this Agreement or the documents 
referred to in this Agreement can be discharged by one party, in whole or in 
part, by a waiver or renunciation of the claim or right unless in writing 
signed by the other party; (b) no waiver that may be given by a party will be 
applicable except in the specific instance for which it is given; and (c) no 
notice to or demand on one party will be deemed to be a waiver of any 
obligation of such party or of the right of the party giving such notice or 
demand to take further action without notice or demand as provided in this 
Agreement or the documents referred to in this Agreement.

     SECTION 11.4   ENTIRE AGREEMENT AND MODIFICATION. This Agreement 
supersedes all prior agreements between the parties with respect to its 
subject matter and constitutes (along with the documents referred to in this 
Agreement) a complete and exclusive statement of the terms of the agreement 
between the parties with respect to its subject matter. This Agreement may 
not be amended except by a written agreement executed by the party to be 
charged with the amendment.

     SECTION 11.5   EXPENSES.  Except as otherwise expressly provided in this 
Agreement, each party to this Agreement will bear its respective expenses 
incurred in connection with the preparation, execution and performance of 
this Agreement and the Contemplated Transactions,

                                        A-50
<PAGE>

including all fees and expenses of Shipman's Representatives, but not 
including the Additional Transaction Expenses (collectively, "Transaction 
Expenses"), PROVIDED, HOWEVER, that the Transaction Expenses of Shipman and 
the Bank shall not exceed in the aggregate the sum of $50,000, plus the 
amount set forth on Schedule 11.5.  In the event of termination of this 
Agreement, the obligation of each party to pay its own expenses will be 
subject to any rights of such party arising from a breach of this Agreement 
by the other party.

     SECTION 11.6   PUBLICITY.  Any public announcement or similar publicity 
with respect to this Agreement or the Contemplated Transactions will be 
issued, if at all, at such time and in such manner as CNB and Shipman shall 
jointly determine.  Unless consented to by CNB in advance or required by 
Legal Requirements, prior to the Closing Shipman shall, and shall cause the 
Bank to, keep this Agreement strictly confidential and may not make any 
disclosure of this Agreement to any Person.  Shipman and CNB will consult 
with each other concerning the means by which the Bank's employees, customers 
and suppliers and others having dealings with the Bank will be informed of 
the Contemplated Transactions, and CNB will have the right to be present for 
any such communication.

     SECTION 11.7   CONFIDENTIALITY.  Between the date of this Agreement and 
the Closing Date, CNB and Shipman will maintain in confidence, and will cause 
the directors, officers, employees, agents, and advisors of CNB and the Bank 
to maintain in confidence, and not use to the detriment of another party or 
the Bank any written, oral, or other information obtained in confidence from 
another party or the Bank in connection with this Agreement or the 
Contemplated Transactions, unless:  (a) such information is already known to 
such party or to others not bound by a duty of confidentiality or such 
information becomes publicly available through no fault of such party; (b) 
the use of such information is necessary or appropriate in making any filing 
or obtaining any consent or approval required for the consummation of the 
Contemplated Transactions; or (c) the furnishing or use of such information 
is required by or necessary or appropriate in connection with legal 
proceedings. If the Contemplated Transactions are not consummated, each party 
will return or destroy as much of such written information as the other party 
may reasonably request.

     SECTION 11.8   NOTICES.  All notices, consents, waivers and other 
communications under this Agreement must be in writing (which shall include 
telecopier communication) and will be deemed to have been duly given if

Board of Directors
Shipman Bancorp, Inc.
Shipman, Illinois

RE:     FAIRNESS OPINION RELATIVE TO PENDING AGREEMENT OF SHIPMAN BANCORP, 
        INC., SHIPMAN, ILLINOIS, TO MERGE WITH AND INTO CARLINVILLE NATIONAL 
        BANK SHARES, INC., CARLINVILLE, ILLINOIS.

Directors:

The Board of Directors of Shipman Bancorp, Inc. ("Shipman" or the "Company")
retained Southard Financial, in its capacity as a financial valuation and
consulting firm, to render its opinion of the fairness, from a financial
viewpoint, of the acquisition of Shipman by Carlinville National Bank Shares,
Inc. ("CNB"). Southard Financial and its principals have no past, present, or
future contemplated financial, equity, or other interest in either Shipman or
CNB.  This opinion is issued based upon financial data as of March 31, 1998.

APPROACH TO ASSIGNMENT

The approach to this assignment was to consider the following factors:

     -    A review of the financial performance and position of Shipman and
          the value of its common stock;

     -    A review of the financial performance and position of CNB and the
          value of its common stock;

     -    A review of recent bank merger transactions;

     -    A review of the current and historical market prices of bank
          holding companies in Illinois and surrounding states;

     -    A review of the investment characteristics of the common stock of
          Shipman and CNB;

     -    A review of the Agreement and Plan of Merger between CNB and
          Shipman;

     -    An evaluation of the impact of the merger on the expected return
          to the current shareholders of Shipman; and,

     -    An evaluation of other factors as was considered necessary to
          render this opinion.

It is Southard Financial's understanding that the merger and resulting 
exchange of the stock of Shipman for the outstanding common stock of CNB 
constitutes a non-taxable exchange for federal income tax purposes. The 
exchange of Shipman stock for cash may have tax consequences.

DUE DILIGENCE REVIEW PROCESS

In performing this assignment, Southard Financial reviewed the documents
specifically outlined in Exhibit 1 pertaining to Shipman and in Exhibit 2
pertaining to CNB.  

REVIEW OF SHIPMAN BANCORP, INC.

Southard Financial visited with the management of Shipman Bancorp, Inc. in 
Shipman, Illinois.  Discussions included questions regarding the current and 
historical financial position and performance of Shipman, its outlook for the 
future, and other pertinent factors. 

REVIEW OF CARLINVILLE NATIONAL BANK SHARES, INC.

Southard Financial visited with the management of Carlinville National Bank 
Shares, Inc. in Carlinville and Taylorville, Illinois.  Discussions included 
questions regarding the current and historical financial position and 
performance of CNB, its outlook for the future, and other pertinent factors.

MERGER DOCUMENTATION

Southard Financial reviewed the Agreement and Plan of Merger (the 
"Agreement") dated March 27, 1998. Appropriate aspects of this Agreement were 
discussed with the management of Shipman and CNB.  (See Exhibit 3, Terms of 
the Agreement and Plan of Merger.)

LIMITATIONS OF ANALYSIS

Southard Financial did not independently verify the information reviewed, but 
relied on such information as complete and accurate in all material respects. 
Southard Financial did not make any independent evaluation of the assets of 
CNB or Shipman, but reviewed data supplied by the management of both 
institutions.  This opinion is necessarily based upon financial, economic, 
market, and other conditions as they exist and can be evaluated on the date 
hereof.

Southard Financial is not expressing any opinion as to the actual value of 
the common stock of CNB when issued to Shipman's shareholders pursuant to the 
merger or the price at which shares of CNB will trade subsequent to the 
merger.

MAJOR CONSIDERATIONS 

Numerous factors were considered in the overall review of the proposed 
merger.  The review process included considerations regarding Shipman, CNB, 
and the proposed merger.  The major considerations are as follows:

SHIPMAN BANCORP, INC.

     #    Historical earnings;
     #    Historical dividend payments;
     #    Outlook for future performance, earnings, and dividends;
     #    Economic conditions and outlook in Shipman's market;
     #    The competitive environment in Shipman's market;
     #    Comparisons with peer banks and bank holding companies;
     #    Potential risks in the loan and securities portfolios;
     #    Recent minority stock transactions in Shipman's common stock; and,
     #    Other such factors as were deemed appropriate in rendering 
          this opinion.

CARLINVILLE NATIONAL BANK SHARES, INC.

     #    Historical earnings;
     #    Historical dividend payments;
     #    Outlook for future performance, earnings, and dividends;
     #    Economic conditions and outlook in CNB's market;
     #    The competitive environment in CNB's market;
     #    Comparisons with peer banks and bank holding companies;
     #    Recent minority stock transactions in CNB's common stock; and,
     #    Other such factors as were deemed appropriate in rendering
          this opinion.

COMMON FACTORS

     #    Historical and current bank merger pricing; and,
     #    Current market prices for minority blocks of common stocks
          of regional bank holding companies in Illinois and surrounding
          states.

THE PROPOSED MERGER

     #    The terms of the Agreement and Plan of Merger;
     #    The specific pricing of the merger;
     #    Adequacy of the consideration paid to the shareholders of Shipman;
     #    The assumption that the merger will be treated as a tax-free exchange
          with respect to the CNB shares received;
     #    The impact on CNB's capital and liquidity positions;
     #    The historical dividend payments of CNB and the likely impact on the
          dividend income of the current shareholders of Shipman (equivalency of
          cash dividends);

     #    Pro-forma combined income statements for CNB post merger and the
          expected returns to Shipman shareholders (equivalency of earnings
          yield);
     #    The market for minority blocks of CNB common stock; and,
     #    Other such factors as deemed appropriate.

OVERVIEW OF FAIRNESS ANALYSIS

In connection with rendering its opinion, Southard Financial performed a 
variety of financial analyses, which are summarized below.  Southard 
Financial believes that its analyses must be considered as a whole and that 
considering only selected factors could create an incomplete view of the 
analyses and the process underlying the opinion.  The preparation of a 
fairness opinion is a complex process involving subjective judgment and is 
not susceptible to partial analyses.  In its analyses, Southard Financial 
made numerous assumptions, many of which are beyond the control of Shipman 
and CNB.  Any estimates contained in the analyses prepared by Southard 
Financial are not necessarily indicative of future results or values, which 
may vary significantly from such estimates.  Estimates of value of companies 
do not purport to be appraisals or necessarily reflect the prices at which 
companies or their securities may actually be sold.  None of the analyses 
performed by Southard Financial was assigned greater significance than any 
other.

                              ADEQUACY OF TOTAL PRICE

The key consideration in this fairness opinion is the adequacy of the total
price paid by CNB.  Under the terms of the merger (see Exhibit 3), Shipman
shareholders may elect to (1) receive cash of $190 per share, or (2) two shares
of CNB common stock ("the stock option").  The implied value of the transaction
for those shareholders electing the stock option was estimated by Southard
Financial to be approximately $260 per share, based upon an estimated market
value of CNB common stock of $130 per share (see Exhibit 4 - Reasonable
Valuation Range for CNB Common Shares). The following factors were considered:

ANALYSIS OF MARKET TRANSACTIONS

Based upon the merger terms, Shipman shareholders who elect the cash option will
receive 132.2% of estimated March 31, 1998 book value, 21.0 times 1997 earnings,
and 12.6% of March 31, 1998 assets.

Based upon the terms of the merger and reasonable pricing assumptions (see
Exhibit 4) for the common shares of CNB, Shipman shareholders who elect the
stock option will receive approximately 181% of estimated March 31, 1998 book
value, 28.7 times 1997 earnings, and 17.3% of March 31, 1998 assets.

Based upon the review conducted by Southard Financial, and given the financial
characteristics and performance of Shipman, the pricing for Shipman in the
merger is within the range of multiples seen in recent bank acquisitions (see
Exhibit 5).

DISCOUNTED CASH FLOW ANALYSIS

Southard Financial estimated the present value of the future stream of after-tax
cash flow that Shipman could produce on a stand-alone basis through fiscal year
2002 on the basis of capital available for distribution to Shipman shareholders
in the form of dividends.  Southard Financial also estimated the present value
of the future stream of after-tax cash flow that Shipman could produce after
giving effect to, among other things, certain cost savings expected from the
merger on the basis of capital available for distribution to Shipman
shareholders in the form of dividends.  The estimated terminal value was based
upon a multiple of earnings of 15x.  Based upon an investor's required rate of
return of 16%, the analysis indicated a value of Shipman in the range of $185 to
$245 per share.  The implied valuation ranges are consistent with the terms of
the offer from CNB.

LIQUIDITY

Like Shipman stock, CNB shares are not traded on an exchange.  CNB management
indicated that there is a waiting list for the purchase of shares, but that
actual trading activity has been very thin.  Further, except in the case of
officers, directors, and certain large shareholders of Shipman, CNB shares
received will be freely tradable with no restrictions.

MERGER PREMIUM

Based upon the merger terms, Shipman shareholders who elect the cash option will
receive a premium of approximately 25% over the most recent minority trading
price of Shipman shares.  

Based upon the merger terms and reasonable pricing assumptions (See Exhibit 4)
for the common shares of CNB, Shipman shareholders who elect the stock option
will receive a premium of approximately 85% over the most recent minority
trading price of Shipman shares.  

The merger premium for Shipman is consistent with the normal range for similar
transactions.

ANALYSIS OF ALTERNATIVES

In evaluating the fairness of the proposed merger to the shareholders of
Shipman, Southard Financial reviewed with Shipman management the process
undertaken for the sale of the company.  We reviewed other offers received. 
Further, negotiations took place with CNB over about a three and one-half month
period before a definitive agreement was reached.

                IMPACT OF AN EXCHANGE OF SHIPMAN STOCK FOR CNB STOCK

In evaluating the impact of receiving CNB common stock in the merger, the
following factors are relevant:

DIVIDEND YIELD ANALYSIS

In evaluating the impact of the proposed merger on the shareholders of Shipman,
Southard Financial reviewed the dividend paying histories of Shipman and CNB. 
Based upon this review, the impact on the dividends received by Shipman
shareholders who elect to receive CNB common stock will be decidedly positive. 
This is predicated on the assumption that CNB will continue per share dividends
at or above current levels (see Exhibit 4).

EARNINGS YIELD ANALYSIS

In evaluating the impact of the proposed merger on the shareholders of Shipman,
Southard Financial determined that, based upon an exchange ratio of 2:1, the
shareholders of Shipman would have seen a 119.2% increase in earnings per share
(defined as post merger combined earnings per share times the assumed exchange
ratio), had the merger been consummated prior to January 1, 1997 (see Exhibit
4).  

BOOK VALUE ANALYSIS

In evaluating the impact of the proposed merger on the shareholders of Shipman,
Southard Financial determined that the shareholders of Shipman would have
experienced a 56.8% increase in the book value of their investment, based upon
book values of Shipman and CNB at March 31, 1998 (see Exhibit 4).

FUNDAMENTAL ANALYSIS

Southard Financial reviewed the financial characteristics of Shipman and CNB
with respect to profitability, capital ratios, liquidity, asset quality, and
other factors.  Southard Financial compared Shipman and CNB to a universe of
publicly traded banks and bank holding companies and to peer groups prepared by
the Federal Financial Institutions Examination Council (FFIEC).  Southard
Financial found that the post-merger combined entity will have capital ratios
and profitability ratios near those of the public peer group.

SUMMARY OF ANALYSES

The summary set forth does not purport to be a complete description of the
analyses performed by Southard Financial.  The analyses performed by Southard
Financial are not necessarily indicative of actual values, which may differ
significantly from those suggested by such analyses.  Southard Financial did not
appraise any individual assets or liabilities of Shipman or CNB.  Throughout the
due diligence process, all information provided by Shipman, CNB, and third party
sources was relied upon by Southard Financial without independent verification. 
Based upon the analyses discussed above and other analyses performed by Southard
Financial, the impact of the merger on the shareholders of Shipman is expected
to be favorable.

relevant, it is the opinion of Southard Financial that the terms of the offer

                                     TERMS OF THE
                             AGREEMENT AND PLAN OF MERGER


Southard Financial reviewed the Agreement and Plan of Merger dated March 27,
1998, among CNB and Shipman.  The Agreement gives each Shipman shareholder four
options in the merger.  In exchange for Shipman shares owned, each Shipman
shareholder can:

(1)      Elect to receive cash of $190 per share for all shares (Cash
         Election);

(2)      Elect to receive two shares of CNB common stock for each Shipman share
         (Stock Election);

(3)      Elect to receive a stated percentage of the consideration in cash
         (Partial Cash Election) and the remainder in shares of CNB common
         stock (Partial Stock Election); or,

(4)      Elect no preference for cash or CNB common stock (Non-Election).

Notwithstanding these election options, the Agreement contains further
conditions regarding the aggregate elections in the merger:

(1)      In the aggregate, the sum of the number of shares of Shipman to be
         converted into cash plus the number of dissenting shares shall not be
         more than 30% of the total number of outstanding shares of Shipman. 
         The total number of dissenting shares shall be no greater than 10% of
         the number of shares of Shipman common stock issued and outstanding
         immediately prior to the effective time.

(2)      If the aggregate of the sum of the number of shares of Shipman to be
         converted into cash plus the number of dissenting shares exceeds 30%
         of the total consideration, then each Cash Election share shall be
         converted into a combination of cash and shares of CNB common stock
         according to a formula as prescribed in the Agreement.

(3)      A holder of Shipman common stock who does not submit a form of
         election that is received by the Exchange Agent prior to the election
         deadline shall be deemed to have made a non-election.  CNB shall send
         to each holder of Shipman common stock who has not submitted their
         certificates, additional transmittal materials for use in surrendering
         such certificates in exchange for cash.  For purposes of the
         Agreement, each non-election shall be treated as a stock election.

                                      EXHIBIT 3
                                     TERMS OF THE
                             AGREEMENT AND PLAN OF MERGER
                                     (CONTINUED)



No fractional shares will be issued by CNB.  Shipman shareholders who would
otherwise have been entitled to fractional shares (after aggregating all shares
owned) will be paid in cash in an amount equal to $190 times such fractional
part of a share.

The parties intend for the merger to qualify as a "reorganization" under the
Internal Revenue Code.  Thus, the exchange of Shipman stock for CNB stock is
expected to qualify as a tax-free exchange for Federal income tax purposes.  The
exchange of cash for Shipman shares or for fractional shares may have tax
consequences. 

The Agreement may be terminated by either party:

   - upon the mutual consent of each institution;
   - upon a breach by either party of any representation, warranty, obligation,
     or covenant;
   - if the merger is not consummated on or before the date which is ten months
     after March 27, 1998 or such later date as the parties may agree upon; or,
   - under the terms and conditions as set forth in the Agreement.

If the Agreement is terminated due to: (1) Shipman's failure to use its best
efforts to consummate the merger; (2) Shipman's decision to terminate the merger
for reasons other than as prescribed in the Agreement; or, (3) within 24 months
after the termination of the Agreement Shipman enters into an agreement with any
party other than CNB providing for the acquisition of control, then Shipman is
obligated to pay to CNB a termination fee of $200,000.

Further, if the Agreement is terminated due to: (1) CNB's failure to use its
best efforts to consummate the merger; or (2) CNB's decision to terminate the
merger for reasons other than as prescribed in the Agreement, then CNB is
obligated to pay an amount equal to the sum of all expenses incurred in
connection with the audit of Shipman's books and records.

The following is a summary of the various analyses undertaken in conjunction
with this fairness opinion. This summary is not intended to represent all
analyses performed by Southard Financial, but is presented here for the
convenience of Shipman and its shareholders.

According to the Agreement, the Exchange Ratio is 2.0 shares of CNB common stock
for each share of Shipman common stock outstanding, with the consideration being
a combination of cash and CNB common stock.  The ultimate mix of cash and CNB
common stock to be exchanged in the merger is not currently known, nor can it be
reasonably foreseen.  Therefore, the following analysis focuses on the total
consideration to be paid in the merger, regardless of the mix of cash and CNB
common stock.  The analysis presented below is provided to Shipman shareholders
to assist in their determination of which exchange options to accept.  However,
Southard Financial is not providing investment advice.

EARNINGS

     Shipman earned $9.06 per share in 1997, while CNB earned $9.93 per share in
     1997.  Had the merger been consummated prior to January 1, 1997, each
     former Shipman share would have earned $19.92 (CNB expected earnings of
     $9.93 per share times 2 equivalent shares), or 119.2% more than Shipman's
     earnings. 
     
     Excluding merger related expenses, Shipman would have earned $10.63 per
     share in 1997.  Absent merger related expenses, had the merger been
     consummated prior to January 1, 1997, each former Shipman share would have
     earned 86.8% more than Shipman's earnings. 
     
     Shipman is budgeted (exclusive of any merger related expenses) to earn
     $12.80 per share in 1998, while CNB is expected to earn $11.25 per share in
     1998.  Had the merger been consummated prior to January 1, 1998, each
     former Shipman share would have been expected to earn $22.50 (CNB expected
     earnings of $11.25 per share times 2 equivalent shares), or 75.8% more than
     Shipman's budgeted earnings. 

DIVIDENDS

     Dividends of $2.50 were paid to Shipman shareholders in 1997, while CNB's
     1997 dividend was $2.75 per share.  Had the merger been consummated prior
     to January 1, 1997, each former share of Shipman stock would be expected to
     receive dividends of $5.50 in 1997 (CNB dividends of $2.75 per share times
     2 equivalent shares), or 120.0% more than they received from Shipman.  The
     favorable dividend comparison is a major factor in favor of the merger.
     
     CNB's expected dividend (Southard Financial's estimate) for 1998 is $2.95
     per share.  Thus, assuming the same dividend level for Shipman in 1998 as
     in 1997, the favorable dividend comparison is enhanced.

                            EXPECTED IMPACT OF THE MERGER
                               ON THE SHAREHOLDERS OF
                               SHIPMAN BANCORP, INC.
                                    (CONTINUED)



BOOK VALUE

     Book value of Shipman common stock at December 31, 1997 was $139.17 per
     share.  Book value of CNB was $109.56 per share at December 31, 1997.  If
     the merger was consummated as of December 31, 1997, each former Shipman
     share would have book value of $219.12  (CNB book value of $109.56 per
     share times 2 equivalent shares), or 157.4% of Shipman's book value at
     December 31, 1997.
     
     Estimated book value of Shipman common stock at March 31, 1998 was $143.69
     per share.  Estimated book value of CNB was $112.62 per share at March 31,
     1998.  If the merger was consummated as of March 31, 1998, each former
     Shipman share would be expected to receive book value of $225.24  (CNB
     estimated book value of $112.62 per share times 2 equivalent shares), or
     156.8% of Shipman's estimated book value at March 31, 1998.
     
LIQUIDITY

     Like Shipman stock, CNB shares are not traded on an exchange.  However, the
     management of CNB indicated that there is a list of potential buyers with
     no sellers.  However, it must be noted that the trading activity in CNB
     stock has been very thin. Finally, with minor exceptions, CNB shares
     received by Shipman shareholders will be freely tradable with no
     restrictions.

REASONABLE VALUATION RANGE FOR CNB COMMON SHARES

     Southard Financial was not asked to, and did not, prepare a market
     valuation of the common stock of CNB as of the date of this opinion.  
     However, Southard Financial is actively involved in the preparation of
     appraisals of the common stock of inactively traded bank stocks.  Based
     upon our review, a valuation range of 10 to 13 times estimated 1998
     earnings of $11.25 per share is reasonable.  The implied valuation range is
     $112 to $146 per share.  The valuation range represents 100% to 130% of
     CNB's estimated March 31, 1998 book value. For purposes of evaluating the
     stock exchange offer, a price for CNB stock of $130 per share is, in our
     opinion, reasonable.  Again, it must be noted that Southard Financial is
     not expressing any opinion as to the actual value of the common stock of
     CNB when issued to Shipman's shareholders pursuant to the merger or the
     price at which CNB shares will trade subsequent to the merger.

MERGER PREMIUM

     Prior to the announcement of the merger, Shipman's shares had traded in the
     range of $135.00-$155.00 per share.  Thus, the proposed cash price
     represents a premium to 23% to 40% above the most recent minority interest
     trading price of Shipman common stock.  Based upon the estimated market
     value of CNB shares ($130 per share), the proposed price represents a
     premium to 68% to 93% above the most recent minority interest trading price
     of Shipman common stock.  The premiums are consistent with normal merger
     premiums.

                            TO PUBLIC MARKET TRANSACTIONS

Southard Financial compared the pricing terms of the Agreement to the pricing of
recent acquisitions of banks and bank holding companies across the United
States, and to the minority interest prices of publicly traded banks and bank
holding companies in the Mid West.

Pricing data for recent acquisitions of banks and bank holding companies
(nationwide and in Illinois) is summarized as follows:

     assets under $1 billion for which sufficient data was available
   3 Based upon the cash merger price of $190.00 per share, 1997 earnings of
     $9.06 per share, estimated book value of $143.69 per share at
     March 31, 1998, and assets of $1,506.91 per share at March 31, 1998.
   4 Based upon the stock equivalent merger price of $260.00 per share, 1997
     earnings of $9.06 per share, estimated book value of $143.69 per share at
     March 31, 1998, and assets of $1,506.91 per share at March 31, 1998.

Based upon a cash price of $190.00 per share, the merger of Shipman into CNB 
will take place at 20.97 times 1997 earnings, 136.5% of December 31, 1997 
book value, and 132.2% of estimated book value as of March 31, 1998.  
Further, based upon an Exchange Ratio of 2:1, the merger of Shipman into CNB 
will take place at 28.70 times 1997 earnings, 186.8% of December 31, 1997 
book value, and 180.9% of estimated book value as of March 31, 1998.  The 
price/earnings ratios are comparable to market transactions, while the 
price/book value multiples are below recent market multiples.  Finally, the 
price/assets multiples are below recent market transactions.  However, for 
shareholders who elect to receive stock, the ratios are all near those for 
transactions with comparable ROAE.

In determining the attractiveness of owning CNB stock, it is important to
examine CNB's value in comparison with recent pricing multiples for publicly
traded banks and bank holding companies.  This pricing data is presented below
as of March 31, 1998.

     1 Through March 31, 1998; subject to certain screens performed by Southard
       Financial.
     2 Based on 1997 earnings of $9.93 per share, December 31, 1997 book value
       of $109.56 per share, and 1997 dividends of $2.75 per share.
     3 Based on projected 1998 earnings of $11.25 per share, March 31, 1998
       book value of $112.62 per share, and expected 1998 dividends of $2.95
       per share.

Based upon an analysis of the data provided above, CNB's price/earnings 
multiple and price/book value multiple are both well below the averages for 
public banks, while CNB's dividend yield is above the range of public banks.  
The unfavorable comparison with public banks primarily reflects the 
differential between CNB and the public banks in terms of growth, size, 
diversification, return on equity, management depth, etc.

SECTION 11.65. RIGHT TO DISSENT

     Section 11.65. Right to Dissent. (a) A stockholder of a corporation is 
entitled to dissent from, and obtain payment for his or her shares in the 
event of any of the following corporate actions:

     (1)  consummation of a plan of merger or consolidation or a plan of 
share exchange to which the corporation is a party if: (i) stockholder 
authorization is required for the merger or consolidation or the share 
exchange by Section 11.20 or the articles of incorporation or (ii) the 
corporation is a subsidiary that is merged with its parent or another 
subsidiary under Section 11.30;

     (2)  consummation of a sale, lease or exchange of all, or substantially 
all, of the property and assets of the corporation other than in the usual 
and regular course of business;

     (3)  an amendment of the articles of incorporation that materially and 
adversely affects rights in respect of a dissenter's shares because it:

          (i)  alters or abolishes a preferential right of such shares;

          (ii) alters or abolishes a right in respect of redemption, including a
     provision respecting a sinking fund for the redemption or repurchase, of 
     such shares;

          (iii) in the case of a corporation incorporated prior to January 1, 
     1982, limits or eliminates cumulative voting rights with respect to such 
     shares; or

     (4)  any other corporate action taken pursuant to a stockholder vote if 
the articles of incorporation, by-laws, or a resolution of the board of 
directors provide that stockholders are entitled to dissent and obtain 
payment for their shares in accordance with the procedures set forth in 
Section 11.70 or as may be otherwise provided in the articles, by-laws or 
resolution.

     (b)  A stockholder entitled to dissent and obtain payment for his or her 
shares under this Section may not challenge the corporate action creating his 
or her entitlement unless the action is fraudulent with respect to the 
stockholder or the corporation or constitutes a breach of a fiduciary duty 
owed to the stockholder.

     (c)  A record owner of shares may assert dissenters' rights as to fewer 
than all the shares recorded in such person's name only if such person 
dissents with respect to all shares beneficially owned by any one person and 
notifies the corporation in writing of the name and address of each person on 
whose behalf the record owner asserts dissenters' rights. The rights of a 
partial dissenter are determined as if the shares as to which dissent is made 
and the other shares were recorded in the names of different stockholders. A 
beneficial owner of shares who is not the record owner may assert dissenters' 
rights as to shares held on such person's behalf only if the beneficial owner 
submits to the corporation the record owner's written consent to the dissent 
before or at the same time the beneficial owner asserts dissenters' rights.

SECTION 11.70. PROCEDURE TO DISSENT

                                       C-1
<PAGE>

     Section 11.70.  Procedure to Dissent. (a) If the corporate action giving 
rise to the right to dissent is to be approved at a meeting of stockholders, 
the notice of meeting shall inform the stockholders of their right to dissent 
and the procedure to dissent. If, prior to the meeting, the corporation 
furnishes to the stockholders material information with respect to the 
transaction that will objectively enable a stockholder to vote on the 
transaction and to determine whether or not to exercise dissenters' rights, a 
stockholder may assert dissenters' rights only if the stockholder delivers to 
the corporation before the vote is taken a written demand for payment for his 
or her shares if the proposed action is consummated, and the stockholder does 
not vote in favor of the proposed action.

     (b)  If the corporate action giving rise to the right to dissent is not 
to be approved at a meeting of stockholders, the notice to stockholders 
describing the action taken under Section 11.30 or Section 7.10 shall inform 
the stockholders of their right to dissent and the procedure to dissent. If, 
prior to or concurrently with the notice, the corporation furnishes to the 
stockholders material information with respect to the transaction that will 
objectively enable a stockholder to determine whether or not to exercise 
dissenters' rights, a stockholder may assert dissenter's rights only if he or 
she delivers to the corporation 30 days from the date of mailing the notice a 
written demand for payment for his or her shares.

     (c)  Within 10 days after the date on which the corporate action giving 
rise to the right to dissent is effective or 30 days after the stockholder 
delivers to the corporation the written demand for payment, whichever is 
later, the corporation shall send each stockholder who has delivered a 
written demand for payment a statement setting forth the opinion of the 
corporation as to the estimated fair value of the shares, the corporation's 
latest balance sheet as of the end of a fiscal year ending not earlier than 
16 months before the delivery of the statement, together with the statement 
of income for that year and the latest available interim financial 
statements, and either a commitment to pay for the shares of the dissenting 
stockholder at the estimated fair value thereof upon transmittal to the 
corporation of the certificate or certificates, or other evidence of 
ownership, with respect to the shares, or instructions to the dissenting 
stockholder to sell his or her shares within 10 days after delivery of the 
corporation's statement to the stockholder. The corporation may instruct the 
stockholder to sell only if there is a public market for the shares at which 
the shares may be readily sold. If the stockholder does not sell within that 
10 day period after being so instructed by the corporation, for purposes of 
this Section the stockholder shall be deemed to have sold his or her shares 
at the average closing price of the shares, if listed on a national exchange, 
or the average of the bid and asked price with respect to the shares quoted 
by a principal market maker, if not listed on a national exchange, during 
that 10 day period.

     (d)  A stockholder who makes written demand for payment under this 
Section retains all other rights of a stockholder until those rights are 
canceled or modified by the consummation of the proposed corporate action. 
Upon consummation of that action, the corporation shall pay to each dissenter 
who transmits to the corporation the certificate or other evidence of 
ownership of the shares the amount the corporation estimates to be the fair 
value of the shares, plus accrued interest, accompanied by a written 
explanation of how the interest was calculated.

     (e)  If the stockholder does not agree with the opinion of the 
corporation as to the estimated fair value of the shares or the amount of 
interest due, the stockholder, within 30 days from the delivery of the 
corporation's statement of value, shall notify the corporation in writing of 
the stockholder's estimated fair value and amount of the interest due and 
demand payment for the difference between the stockholder's estimate of fair 
value and interest due and the amount of the payment by the corporation or 
the proceeds of sale by the stockholder, whichever is applicable because of 
the procedure for which the corporation opted pursuant to subsection (c).

     (f)  If, within 60 days from delivery to the corporation of the 
stockholder notification of estimate of fair value of the shares and interest 
due, the corporation and the dissenting stockholder have not agreed in 
writing upon the fair value of the shares and interest due, the corporation 
shall either pay the difference in value demanded by the stockholder, with 
interest, or file a petition in the circuit court of the county in which 
either the registered office or the principal office of the corporation is 
located, requesting the court to determine the fair value of the shares and 
interest due. The corporation shall make all dissenters, whether or not 
residents of this State, whose demands remain unsettled parties to the 
proceeding as an action against their shares and all parties shall be served 
with a copy of the petition. Nonresidents may be served by registered or 
certified mail or by

                                       C-2
<PAGE>

publication as provided by law. Failure of the corporation to commence an 
action pursuant to this Section shall not limit or affect the right of the 
dissenting stockholders to otherwise commence an action as permitted by law.

     (g)  The jurisdiction of the court in which the proceeding is commenced 
under subsection (f) by a corporation is plenary and exclusive. The court may 
appoint one or more persons as appraisers to receive evidence and recommend 
decision on the question of fair value. The appraisers have the power 
described in the order appointing them, or in any amendment to it.

     (h)  Each dissenter made a party to the proceeding is entitled to 
judgment for the amount, if any, by which the court finds that the fair value 
of his or her shares, plus interest, exceeds the amount paid by the 
corporation or the proceeds of sale by the stockholder, whichever amount is 
applicable.

     (i)  The court, in a proceeding commenced under subsection (f), shall 
determine all costs of the proceeding, including the reasonable compensation 
and expenses of the appraisers, if any, appointed by the court under 
subsection (g), but shall exclude the fees and expenses of counsel and 
experts for the respective parties. If the fair value of the shares as 
determined by the court materially exceeds the amount which the corporation 
estimated to be the fair value of the shares or if no estimate was made in 
accordance with subsection (c), then all or any part of the costs may be 
assessed against the corporation. If the amount which any dissenter estimated 
to be the fair value of the shares materially exceeds the fair value of the 
shares as determined by the court, then all or any part of the costs may be 
assessed against that dissenter. The court may also assess the fees and 
expenses of counsel and experts for the respective parties, in amounts the 
court finds equitable, as follows:

     (1)  Against the corporation and in favor of any or all dissenters if 
          the court finds that the corporation did not substantially comply with
          the requirements of subsections (a), (b), (c), (d), or (f).

     (2)  Against either the corporation or a dissenter and in favor of any
          other party if the court finds that the party against whom the fees 
          and expenses are assessed acted arbitrarily, vexatiously, or not in 
          good faith with respect to the rights provided by this Section.

     If the court finds that the services of counsel for any dissenter were 
of substantial benefit to other dissenters similarly situated and that the 
fees for those services should not be assessed against the corporation, the 
court may award to that counsel reasonable fees to be paid out of the amounts 
awarded to the dissenters who are benefited. Except as otherwise provided in 
this Section, the practice, procedure, judgment and costs shall be governed 
by the Code of Civil Procedure.

     (j)  As used in this Section:

     (1)  "Fair value", with respect to a dissenter's shares, means the value of
          the shares immediately before the consummation of the corporate action
          to which the dissenter objects excluding any appreciation or 
          depreciation in anticipation of the corporate action, unless exclusion
          would be inequitable.

     (2)  "Interest" means interest from the effective date of the corporate
          action until the date of payment, at the average rate currently paid 
          by the corporation on its principal bank loans or, if none, at a rate
          that is fair and equitable under all the circumstances.

                                       C-3

                 PART II.  INFORMATION NOT REQUIRED IN PROSPECTUS 

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Pursuant to Section 145 of the Delaware General Corporation Law (the 
"DGCL"), a corporation may indemnify any person who was or is a party or is 
threatened to be made a party to an action (other than an action by or in the 
right of the corporation) by reason of his service as a director or officer 
of the corporation, or his service, at the corporation's request, as a 
director, officer, employee or agent of another corporation or other 
enterprise, against expenses (including attorneys' fees) that are actually 
and reasonably incurred by him ("Expenses"), and judgments, fines and amounts 
paid in settlement that are actually and reasonably incurred by him, in 
connection with the defense or settlement of such action, provided that he 
acted in good faith and in a manner he reasonably believed to be in or not 
opposed to the corporation's best interests and, with respect to any criminal 
action or proceeding, he had no reasonable cause to believe that his conduct 
was unlawful.  Although Delaware law permits a corporation to indemnify any 
person referred to above against Expenses in connection with the defense or 
settlement of an action by or in the right of the corporation, provided that 
he acted in good faith and in a manner he reasonably believed to be in or not 
opposed to the corporation's best interests, if such person has been judged 
liable to the corporation, indemnification is only permitted to the extent 
that the Court of Chancery (or the court in which the action was brought) 
determines that, despite the adjudication of liability, such person is 
entitled to indemnity for such Expenses as the court deems proper.  The 
determination as to whether a person seeking indemnification has met the 
required standard of conduct is to be made (1) by a majority vote of a quorum 
of disinterested members of the board of directors, or (2) by independent 
legal counsel in a written opinion, if such a quorum does not exist or if the 
disinterested directors so direct, or (3) by the stockholders.  The General 
Corporation Law of the State of Delaware also provides for mandatory 
indemnification of any director, officer, employee or agent against Expenses 
to the extent such person has been successful in any proceeding covered by 
the statute.  In addition, the DGCL provides the general authorization of 
advancement of a director's or officer's litigation expenses in lieu of 
requiring the authorization of such advancement by the board of directors in 
specific cases, and that indemnification and advancement of expenses provided 
by the statute shall not be deemed exclusive of any other rights to which 
those seeking indemnification or advancement of expenses may be entitled 
under any by-law, agreement or otherwise.  CNB's Amended and Restated 
Certificate of Incorporation (the "Certificate") and its Bylaws (the 
"Bylaws") repeat the provisions of Section 145 of the DGCL, except that the 
Bylaws REQUIRE CNB to indemnify its directors, officers, employees and other 
agents and the Certificate only PERMITS CNB to provide this indemnification.

     CNB's Certificate is consistent with Section 102(b)(7) of the DGCL, 
which generally permits a company to include a provision limiting the 
personal liability of a director in the company's certificate of 
incorporation. With limitations, this provision eliminates the personal 
liability of CNB's directors to CNB or its stockholders for monetary damages 
for breach of fiduciary duty as a director. However, this provision does not 
eliminate director liability: (1) for breaches of the duty of loyalty to CNB 
and its stockholders; (2) for acts or omissions not in good faith or which 
involve intentional misconduct or a knowing violation of law; (3) for 
transactions from which a director derives improper personal benefit; or (4) 
under Section 174 of the DGCL ("Section 174").  Section 174 makes directors 
personally liable for unlawful dividends and stock repurchases or redemptions 
and expressly sets forth a negligence standard with respect to such 
liability.  While this provision protects the directors from awards for 
monetary damages for breaches of their duty of care, it does not eliminate 
their duty of care. The limitations in this provision have no effect on 
claims arising under the federal securities laws.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes as follows:  that prior to 
any public reoffering of the securities registered hereunder through use of a 
Prospectus which is a part of this registration statement, by any person or 
party who is deemed to be an underwriter within the meaning of Rule 145(c), 
the issuer undertakes that such reoffering Prospectus will contain the 
information called for by the applicable registration form with respect to 
reofferings by persons who may be deemed underwriters, in addition to the 
information called for by the other items of the applicable form.

     The undersigned registrant hereby undertakes that every Prospectus: (i) 
that is filed pursuant to the immediately preceding paragraph, or (ii) that 
purports to meet the requirements of Section 10(a)(3) of the Act and is used 
in connection with an offering of securities subject to Rule 415, will be 
filed as a part of an amendment to the registration statement and will not be 
used until such amendment is effective, and that, for purposes of determining 
any liability under the Act, each such post-effective amendment shall be 
deemed to be a new

                                       II-2
<PAGE>

registration statement relating to the securities offered therein, and the 
offering of such securities at that time shall be deemed to be the initial 
bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Act may be 
permitted to directors, officers and controlling persons of the registrant 
pursuant to the foregoing provisions, or otherwise, the registrant has been 
advised that in the opinion of the Securities and Exchange Commission such 
indemnification is against public policy as expressed in the Act and is, 
therefore, unenforceable. In the event that a claim for indemnification 
against such liabilities (other than the payment by the registrant of 
expenses incurred or paid by a director, officer or controlling person of the 
registrant in the successful defense of any action, suit or proceeding) is 
asserted by such director, officer or controlling person in connection with 
the securities being registered, the registrant will, unless in the opinion 
of its counsel the matter has been settled by controlling precedent, submit 
to a court of appropriate jurisdiction the question whether such 
indemnification by it is against public policy as expressed in the Act and 
will be governed by the final adjudication of such issue.

     The undersigned registrant hereby undertakes to respond to requests for 
information that is incorporated by reference into the Proxy 
Statement/Prospectus  pursuant to items 4, 10(b), 11, or 13 of this form, 
within one business day of receipt of such request, and to send the 
incorporated documents by first class mail or other equally prompt means.  
This includes information contained in the documents filed subsequent to the 
effective date of this registration statement through the date of responding 
to the request.

     The undersigned registrant hereby undertakes to supply by means of a 
post-effective amendment all information concerning a transaction, and the 
company being acquired involved therein, that was not the subject of and 
included in this registration statement when it became effective.

     The Board of Directors shall have the power to define the duties of the 
officers and employees of the Corporation, to fix the salaries to be paid to 
them; to dismiss them; to require bonds from them and to fix the penalty 
thereof; to regulate the manner in which any increase of the capital of the 
Corporation shall be made; to manage and administer the business and affairs 
of the Corporation; to make all bylaws that it may be lawful for them to

                                INDEMNIFICATION

     (a)  This Corporation shall have the power to indemnify any person who 
was or is a party or is threatened to be made a party to any threatened, 
pending or completed action, suit or proceeding, whether civil, criminal, 
administrative or investigative (other than an action by or in the right of 
the Corporation) by reason of the fact that he is or was a director, officer, 
employee or agent of the Corporation, or is or was serving at the request of 
the Corporation as a director, officer, employee or agent of another 
corporation, partnership, joint venture, trust or other enterprise, against 
expenses (including attorneys' fees), judgments, fines and amounts paid in 
settlement actually and reasonably incurred by him in connection with such 
action, suit or proceeding if he acted in good faith and in a manner he 
reasonably believed to be in or not opposed to the best interests of the 
Corporation, and, with respect to any criminal action or proceeding, had no 
reasonable cause to believe his conduct was unlawful. The termination of any 
action, suit or proceeding, by judgment, order, settlement, conviction, or 
upon a plea of NOLO CONTENDRE or its equivalent, shall not, of itself, create 
a presumption that the person did not act in good faith and in a manner which 
he reasonably believed to be in or not opposed to the best interests of the 
Corporation, and, with respect to any criminal action or proceeding, had 
reasonable cause to believe that his conduct was unlawful.

     (b)  This Corporation shall have the power to indemnify any person who 
was or is a party or is threatened to be made a party to any threatened, 
pending or completed action or suit by or in the right of Corporation to 
procure a judgment in its favor by reason of the fact that he is or was a 
director, officer, employee or agent of the Corporation, or is or was serving 
at the request of the Corporation as a director, officer, employee or agent 
of another corporation, partnership, joint venture, trust or other 
enterprise, against expenses (including attorneys' fees) actually and 
reasonably incurred by him in connection with the defense or settlement of 
such action or suit if he acted in good faith and in a manner he reasonably 
believed to be in or not opposed to the best interest of the Corporation and 
except that no indemnification shall be made in respect of any claim, issue 
or matter as to which such person shall have been adjudged to be liable for 
negligence or misconduct in the performance of his duty to the Corporation 
unless and only to the extent that the court in which such action or suit was 
brought shall determine upon application that, despite the adjudication of 
liability but in view of all the circumstances of the case, such person is 
fairly and reasonably entitled to indemnity for such expenses which such 
court shall deem proper.


                                        3

<PAGE>

     (c)  Any indemnification under subsections (a) and (b) (unless order by 
a court) shall be made by the Corporation only as authorized in the specific 
case upon a determination that indemnification of the director, officer, 
employee or agent is proper in the circumstances because he has met the 
applicable standard of conduct set forth in subsections (a) and (b).  Such 
determination shall be made (i) by the Board of Directors by a majority vote 
of a quorum consisting of directors who were not parties to such action, suit 
or proceedings, or (ii) if such a quorum is not obtainable, or, even if 
obtainable a quorum of disinterested directors so directs, by independent 
legal counsel in a written opinion, or (iii) by the stockholders.

     (d)  Expenses incurred in defending a civil or criminal action, suit or 
proceeding may be paid by the Corporation in advance of the final disposition 
of such action, suit or proceeding as authorized by the Board of Directors in 
the specific case upon receipt of an undertaking by or on behalf of the 
director, officer, employee or agent to repay such amount unless it shall 
ultimately be determined that he is entitled to be indemnified by the 
Corporation as authorized in this section.
                                       
     (e)  The indemnification provided by this section shall not be deemed 
exclusive of any other rights to which those seeking indemnification may be 
entitled under any bylaw, agreement, vote of stockholders or disinterested 
directors or otherwise, both as to action in his official capacity and as to 
action in another capacity while holding such office, and shall continue as 
to a person who has ceased to be a director, officer, employee or agent and 
shall inure to the benefit of the heirs, executors and administrators of such 
a person.
                                       
     (f)  This Corporation shall have power to purchase and maintain 
insurance on behalf of any person which is or was a director, officer, 
employee or agent of the Corporation, or is or was serving at the request of 
the Corporation as a director, officer, employee or agent of another 
corporation, partnership, joint venture, trust or other enterprise, against 
any liability asserted against him and incurred by him in any such capacity, 
or arising out of his status as such, whether or not the Corporation would 
have the power to indemnify him against such liability under the provisions 
of this section.
                                       
                                       
                                  ARTICLE XI
                                       
                              DIRECTORS LIABILITY

     Directors of this Corporation shall not be liable to either this 
Corporation or its stockholders for monetary damages for a breach of 
fiduciary duties unless the breach involves: (i) a director's duty of loyalty 
to this Corporation or its stockholders; (ii) acts or omissions not in good 
faith or which involve intentional misconduct or a knowing violation of the 
law; (iii) liabilities for unlawful payments of dividends or unlawful stock 
purchases or redemption by this Corporation; or (iv) a transaction from which 
the director derived an improper personal benefit.

                         CARLINVILLE NATIONAL BANK SHARES, INC.

                                        ARTICLE I

     SECTION 1.  ANNUAL MEETING.  An annual meeting of the shareholders shall 
be held on the third Tuesday in March of each year for the purpose of 
electing directors and for the transaction of such other businesses as may 
come before the meeting.  If the day fixed for the annual meeting shall be a 
legal holiday, such meeting shall be held on the next succeeding business day.

     SECTION 2.  SPECIAL MEETINGS.  Special meetings of the shareholders may 
be called either by the president, by the board of directors or by the 
holders of not less than one-fifth of all the outstanding shares of the 
corporation entitled to vote, for the purpose or purposes stated in the call 
of the meeting.

     SECTION 3.  PLACE OF MEETING.  The board of directors may designate any 
place, as the place of meeting for any annual meeting or for any special 
meeting called by the board of directors.  If no designation is made, or if a 
special meeting be otherwise called, the place of meeting shall be at West 
Side Square, Carlinville, IL 62626.

     SECTION 4.  NOTICE OF MEETINGS.  Written notice stating the place, date, 
and hour of the meeting and, in the case of a special meeting, the purpose or 
purposes for which the meeting is called, shall be delivered not less than 
ten nor more than forty days before the meeting, or in the case of a merger 
or 

<PAGE>

consolidation not less than twenty nor more than forty days before the 
meeting, either personally or by mail, by or at the direction of the 
president, or the secretary, or the officer or persons calling the meeting, 
to each shareholder of record entitled to vote at such meeting.  If mailed, 
such notice shall be deemed to be delivered when deposited in the United 
States mail, addressed to the shareholder at his address as it appears on the 
records of the corporation, with postage thereon prepaid.  When a meeting is 
adjourned to another time or place, notice need not be given of the adjourned 
meeting if the time and place thereof are announced at the meeting at which 
the adjournment is taken.

     SECTION 5.  FIXING OF RECORD DATE.  For the purpose of determining the 
shareholders entitled to notice of or to vote at any meeting of shareholders, 
or any adjournment thereof, or to express consent to corporate action in 
writing without a meeting, or to receive payment of any dividend, or other 
distribution or allotment of any rights, or to exercise any rights in respect 
of any change, conversion or exchange of shares or for the purpose of any 
other lawful action, the board of directors of the corporation may fix in 
advance a record date which shall not be more than sixty days and, for a 
meeting of shareholders, not less than ten days, or in the case of a merger 
or consolidation not less than twenty days, before the date of such meeting.  
If no record date is fixed, the record date for the determination of 
shareholders entitled to notice of or to vote at a meeting of shareholders 
shall be the date on which notice of meeting is mailed, and the record date 
for the determination of shareholders for any other purpose shall be the date 
on which the board of directors adopts the resolutions relating thereto.  A 
determination of shareholders of record entitled to notice of or to vote at a 
meeting of shareholders shall apply to any adjournment of the meeting.

     SECTION 6.  VOTING LISTS.  The officer or agent having charge of the 
transfer book for shares of the corporation shall make at least ten days 
before each meeting of shareholders, a complete list of the shareholders 
entitled to vote at such meeting, arranged in alphabetical order, showing the 
address of and the number of shares registered in the name of the 
shareholder, which list, for a period of ten days prior to such meeting, 
shall be kept on file at the main office of the corporation and shall be open 
to inspection by any shareholder for any purpose germane to the meeting, at 
any time during usual business hours.  Such list shall also be produced and 
kept open at the time and place of the meeting and may be inspected by any 
shareholder during the whole time of the meeting.  The original share ledger 
or transfer book, or a duplicate thereof kept in this State, shall be prima 
facie evidence as to who are the 

<PAGE>

shareholders entitled to examine such list or share ledger or transfer book 
or to vote at any meeting of shareholders.

     SECTION 7.  QUORUM.  The holders of a majority of the outstanding shares 
of the corporation, present in person or represented by proxy, shall 
constitute a quorum at any meeting of shareholders; provided that if less 
than a majority of the outstanding shares are represented at said meeting, a 
majority of the shares so represented may adjourn the meeting at any time 
without further notice.  If a quorum is present, the affirmative vote of the 
majority of the shares represented at the meeting shall be the act of the 
shareholders, unless the vote of a greater number is required by statute, the 
certificate of incorporation or these by-laws.  At any adjourned meeting at 
which a quorum shall be present, any business may be transacted which might 
have been transacted at the original meeting.  Withdrawal of shareholders 
from any meeting shall not cause failure of a duly constituted quorum at that 
meeting.

     SECTION 8.  PROXIES.  Each shareholder entitled to vote at a meeting of 
shareholders or to express consent or dissent to corporate action in writing 
without a meeting may authorize another person or persons to act for him by 
proxy, but no such proxy shall be valid after eleven months from the date of 
its execution, unless otherwise provided in the proxy.

     SECTION 9.  VOTING OF SHARES.  Each outstanding share shall be entitled 
to one vote upon each matter submitted to vote at a meeting of shareholders.

     SECTION 10.  VOTING OF SHARES BY CERTAIN HOLDERS. Shares standing in the 
name of another corporation, domestic or foreign, may be voted by such 
officer, agent, or proxy as the by-laws of such corporation may prescribe, 
or, in the absence of such provision, as the board of directors of such 
corporation may determine.

     Shares standing in the name of a deceased person, a minor ward or an 
incompetent person, may be voted by his administrator, executor, court 
appointed guardian, or conservator, either in person or by proxy without a 
transfer of such shares into the name of such administrator, executor, court 
appointed guardian, or conservator.  Shares standing in the name of a trustee 
may be voted by him, either in person or by proxy.  Shares of stock held by 
the Carlinville National Bank Trust Department shall be considered for quorum 
purposes only.

     Shares standing in the name of a receiver may be voted by such receiver, 
and shares held by or under the control of a receiver may be voted by such 
receiver without the transfer 

<PAGE>

thereof into his  name if authority so to do be contained in an appropriate 
order of the court by which such receiver was appointed.

     A shareholder whose shares are pledged shall be entitled to vote such 
shares until the shares have been transferred into the name of the pledgee, 
and thereafter the pledgee shall be entitled to vote the share so transferred.

     Any number of shareholders may create a voting trust for the purpose of 
conferring upon a trustee or trustees the right to vote or otherwise 
represent their shares, for a period not to exceed ten years, by entering 
into a written voting trust agreement specifying the terms and conditions of 
the voting trust, and by transferring their shares to such trustee or 
trustees for the purpose of the agreement.  Any such trust agreement shall 
not become effective until a counterpart of the agreement is deposited with 
the corporation at its main office.  The counterpart of the voting trust 
agreement so deposited with the corporation shall be subject to the same 
right of examination by a shareholder of the corporation, in person or by 
agent or attorney, as are the books and records of the corporation, and shall 
be subject to examination by any holder of a beneficial interest in the 
voting trust, either in person or by agent or attorney, at any reasonable 
time for any proper purpose.

     SECTION 11.  CUMULATIVE VOTING.  In all elections for directors, every 
shareholder shall have the right to vote, in person or by proxy, the number 
of shares owned by him, for as many persons as there are directors to be 
elected, or to cumulate said shares, and give one candidate as many votes as 
the number of directors multiplied by the number of his shares shall equal, 
or to distribute them on the same principle among as many candidates as he 
shall see fit.

     SECTION 12.  INSPECTORS.  At any meeting of shareholders, the presiding 
officer may, or upon the request of any shareholder, shall appoint one or 
more persons as inspectors for such meeting.

     Such inspectors shall ascertain and report the number of shares 
represented at the meeting, based upon their determination of the validity 
and effect of proxies; count all votes and report the results; and do such 
other acts as are proper to conduct the election and voting with impartiality 
and fairness to all the shareholders.

     Each report of an inspector shall be in writing and signed by him or by 
a majority of them if there be more than one inspector acting at such 
meeting. If there is more than one 

<PAGE>

inspector, the report of a majority shall be the report of the inspectors.  
The report of the inspector or inspectors on the number of shares represented 
at the meeting and the results of the voting shall be prima facie evidence 
thereof.

     SECTION 13.  INFORMAL ACTION BY SHAREHOLDERS.  Any action required to be 
taken at a meeting of the shareholders, or any other action which may be 
taken at a meeting of the shareholders, may be taken without a meeting if a 
consent in writing, setting forth the action so taken, shall be signed by all 
of the shareholders entitled to vote with respect to the subject matter 
thereof.

     SECTION 14.  VOTING BY BALLOT.  Voting on any question or in any 
election may be by voice unless the presiding officer shall order or any 
shareholder shall demand that voting be by ballot.

     SECTION 15.  APPRAISAL RIGHTS.  Appraisal rights shall be available for 
the shares of stock of this corporation as a result of any merger or 
consolidation in which this corporation is a constituent corporation.  Said 
rights shall be exercised in the manner and upon the terms and conditions 
provided by law.

                                   ARTICLE III

                                    DIRECTORS

     SECTION 1.  GENERAL POWERS.  The business of the corporation shall be
managed by or under the direction of its board of directors.

     SECTION 2.  NUMBER, TENURE AND QUALIFICATIONS.  The number of the 
directors of the corporation shall be eight.  Each director shall hold office 
until the next annual meeting of shareholders or until his successor shall 
have been elected and qualified.  Directors need not be residents of 
Illinois.  The number of directors may be increased or decreased from time to 
time by the amendment of this section; but no decrease shall have the effect 
of shortening the term of any incumbent director.

     SECTION 3.  REGULAR MEETINGS.  A regular meeting of the board of 
directors shall be held without other notice than this by-law, immediately 
after the annual meeting of shareholders.  The board of directors may 
provide, by resolution, the time and place for holding of additional regular 
meetings without other notice than such resolution.

     SECTION 4.  SPECIAL MEETINGS.  Special meetings of the board of 
directors may be called by or at the request of the president or any two 
directors.  The person or persons authorized to call 

<PAGE>

special meetings of the board of directors may fix any place as the place for 
holding any special meeting of the board of directors called by them.

     SECTION 5.  NOTICE.  Notice of any special meeting shall be given at 
least 10 days previous thereto by written notice to each director at his 
business address.  If mailed, such notice shall be deemed to be delivered 
when deposited in the United States mail so addressed, with postage thereon 
prepaid.  If notice given by telegram, such notice shall be deemed to be 
delivered when the telegram is delivered to the telegram company.  The 
attendance of a director at any meeting shall constitute a waiver of notice 
of such meeting, except where a director attends a meeting for the express 
purpose of objecting to the transaction of any business because the meeting 
is not lawfully called or convened.  Neither the business to be transacted 
at, nor the purpose of, any regular or special meeting of the board of 
directors need be specified in the notice or waiver of notice of such meeting.

     SECTION 6.   QUORUM.  A majority of the number of directors fixed by 
these by-laws shall constitute a quorum for transaction of business at any 
meeting of the board of directors, provided that if less than a majority of 
such number of directors are present at said meeting, a majority of the 
directors present may adjourn the meeting at any time without further notice.

<PAGE>

     SECTION 7.  MANNER OF ACTING.  The act of the majority of the directors 
present at a meeting at which a quorum is present shall be the act of the 
board of directors, unless the act of a greater number is required by 
statute, these by-laws, or the certificate of incorporation.

     SECTION 8.  VACANCIES.  Any vacancy occurring in the board of directors 
and any directorship to be filled by reason of an increase in the number of 
directors, may be filled by election at an annual meeting or at a special 
meeting of directors called for that purpose.

     SECTION 9.  ACTION WITHOUT A MEETING.  Unless specifically prohibited by 
the certificate of incorporation or by-laws, any action required to be taken 
at a meeting of the board of directors, or any other action which may be 
taken at a meeting of the board of directors, or of any committee thereof may 
be taken without a meeting if a consent in writing, setting forth the action 
so taken, shall be signed by all the directors entitled to vote with respect 
to the subject matter thereof, or by all members of such committee, as the 
case may be.  Any such consent signed by all the directors or all the members 
of the committee shall have the same effect as a unanimous vote, and may be 
stated as such in any document filed with the Secretary of State or with 
anyone else.

     SECTION 10.  COMPENSATION.  The board of directors, by the affirmative 
vote of a majority of directors then in office, and irrespective of any 
personal interest of any of its members, shall have authority to establish 
reasonable compensation of all directors for services to the corporation as 
directors, officers or otherwise.  By resolution of the board of directors, 
the directors may be paid their expenses, if any, of attendance at each 
meeting of the board. No such payment previously mentioned in this section 
shall preclude any director from serving the corporation in any other 
capacity and receiving compensation therefor.

     SECTION 11.  PRESUMPTION OF ASSENT.  A director of the corporation who 
is present at a meeting of the board of directors at which action on any 
corporate matter is taken shall be conclusively presumed to have assented to 
the action taken unless his dissent shall be entered in the minutes of the 
meeting  or unless he shall file his written dissent to such action with the 
person acting as the secretary of the meeting before the adjournment thereof 
or shall forward such dissent by registered  mail to the secretary of the 
corporation immediately after the adjournment of the meeting.  Such right to 
dissent shall not apply to a director who voted in favor of such action.

                                       OFFICERS

     SECTION 1.  NUMBER.  The officers of the corporation shall be a 
president, one or more vice-presidents, and such other officers as may be 
elected or appointed by the board of directors. Any two or more offices may 
be held by the same person, except the offices of president and secretary.

     SECTION 2.  ELECTION AND TERM OF OFFICE.  The officers of the 
corporation shall be elected annually by the board of directors at the first 
meeting of the board of directors held after each annual meeting of 
shareholders.  If the election of officers shall not be held at such meeting, 
such election shall be held as soon thereafter as conveniently may be.  
Vacancies may be filled or new offices created and filled at any meeting of 
the board of directors. Each officer shall hold office until his successor 
shall have been duly elected and shall have qualified or until his death or 
until he shall resign or shall have been removed in the manner hereinafter 
provided.  Election of an officer shall not of itself create contract rights.

     SECTION 3.  REMOVAL.  Any officer elected or appointed by the board of 
directors may be removed by the board of directors whenever in its judgment 
the best interest of the corporation would be served thereby, but such 
removal shall be without prejudice to the contract rights, if any, of the 
person so removed.

     SECTION 4.  PRESIDENT.  The president shall be the principal executive 
officer of the corporation.  Subject to the direction and control of the 
board of directors, he shall be in charge of the business of the corporation; 
he shall see that the resolutions and directions of the board of directors 
are carried into effect except in those instances in which that 
responsibility is specifically assigned to some other person by the board of 
directors; and, in general, he shall discharge all duties incident to the 
office of president and such other duties as may be prescribed by the board 
of directors from time to time.  He shall preside at all meetings of the 
shareholders and of the board of directors.  Except in those instances in 
which the authority to execute is expressly delegated to another officer or 
agent of the corporation or a different mode of execution is expressly 
prescribed by the board of directors or these by-laws, he may execute for the 
corporation certificates for its shares, and any contracts, deeds, mortgages, 
bonds or other instruments which the board of directors has authorized to be 
executed, and he may accomplish such execution either under or without the 
seal 

<PAGE>

of the corporation and either individually or with  any other officer 
thereunto authorized by the board of directors, according to the requirements 
of the form of the instrument.  He may vote all securities which the 
corporation is entitled to vote except as and to the extent such authority 
shall be vested in a 

<PAGE>

different officer or agent of the corporation by the board of directors.

     SECTION 5.  THE VICE-PRESIDENTS.  The vice-president (or in the event 
there be more than one vice-president, each of the vice-presidents) shall 
assist the president in the discharge of his duties as the president may 
direct and shall perform such other duties as from time to time may be 
assigned to him by the president or by the board of directors.  In the 
absence of the president or in the event of his inability or refusal to act, 
the vice-president (or in the event there be more than one vice-president, 
the vice-presidents in the other designated by the board of directors, or by 
the president if the board of directors has not made such a designation, or 
in the absence of any designation, then in the order of seniority of tenure 
as vice-president) shall perform the duties of the president, and when so 
acting, shall have the powers of and be subject to all the restrictions upon 
the president.  Except in those instances in which the authority to execute 
is expressly delegated to another officer or agent of the corporation or a 
different mode of execution is expressly prescribed by the board of directors 
or these by-laws, the vice president (or each of them if there are more than 
one) may execute for the corporation certificates for its shares and any 
contracts, deeds, mortgages, bonds or other instruments which the board of 
directors has authorized to be executed, and he may accomplish such execution 
either under or without the seal of the corporation and either individually 
or with any other officer thereunto authorized by the board of directors, 
according to the requirements of the form of the instrument.

     SECTION 6. SALARIES.  The salaries of the officers shall be fixed from 
time to time by the board of directors and no officer shall be prevented from 
receiving such salary by reason of the fact that he is also a director of the 
corporation.

                                   ARTICLE V.

                              CONTRACTS AND CHECKS

     SECTION 1.  CONTRACTS.  The board of directors may authorize any officer 
or officers, agent or agents, to enter into any contract or execute and 
deliver any instrument in the name of and on behalf of the corporation, and 
such authority may be general or confined to specific instances.

     SECTION 2.  CHECKS, DRAFTS, ETC.  All checks, drafts or other orders for 
the payment of money, notes or other evidences of indebtedness issued in the 
name of the corporation, shall be signed by such officer or officers, agent 
or agents of the 

<PAGE>

corporation and in such manner as shall from time to time be determined by 
resolution of the board of directors.

                                   ARTICLE VI 

                    CERTIFICATES FOR SHARES AND THEIR TRANSFER

     SECTION 1.  CERTIFICATES FOR SHARES.  Certificates representing shares 
of the corporation shall be signed by the president or a vice-president and 
by such officer as shall be designated by resolution of the board of 
directors, and shall be sealed with the seal or a facsimile of the seal of 
the corporation.  If both of the signatures of the officers be by facsimile, 
the certificate shall be manually signed by or on behalf of a duly authorized 
transfer agent or clerk.  Each certificate representing shares shall be 
consecutively numbered or otherwise identified, and shall also state the name 
of the person to whom issued, the number, the date of issue, that the 
corporation is organized under Delaware law, and the par value.

     The name and address of each shareholder, the number and class of shares 
held and the date on which the certificates for the shares were issued shall 
be entered on the books of the corporation.  The person in whose name shares 
stand on the books of the corporation shall be deemed the owner thereof for 
all purposes as regards the corporation.

     SECTION 2.  LOST CERTIFICATES.  If a certificate representing shares has 
allegedly been lost or destroyed the board of directors may in its 
discretion, except as may be required by law, direct that a new certificate 
be issued upon such indemnification and other reasonable requirements as it 
may impose.

     SECTION 3.  TRANSFERS OF SHARES.  Transfer of shares of the corporation 
shall be recorded on the books of the corporation, and except in the case of 
a lost or destroyed certificate, shall be made on surrender for cancellation 
of the certificate for such shares.  A certificate presented for transfer 
must be duly endorsed and accompanied by proper guaranty of signature and 
other appropriate assurances that the endorsement is effective.

                                     ARTICLE VII

                                    FISCAL YEAR

board of directors.


<PAGE>

                                    ARTICLE VIII

                                      DIVIDENDS

     The board of directors may from time to time declare, and the 
corporation may pay, dividends on its outstanding shares in the manner and 
upon the terms and conditions provided by law.

                                     ARTICLE IX

                                     AMENDMENTS

     The power to make, alter, amend, or repeal the by-laws of the 
corporation shall be vested in the board of directors.  The by-laws may 
contain any provisions for the regulation and management of the affairs of 
the corporation not inconsistent with law or the certificate of incorporation.

                                      ARTICLE X

                             INDEMNIFICATION OF OFFICERS,
                           DIRECTORS, EMPLOYEES AND AGENTS

     SECTION 1.  The corporation shall indemnify any person who was or is 
threatened to be made a party to any threatened, pending or completed action, 
suit or proceeding, whether civil, criminal, administrative or investigative 
(other than an action by or in the right of the corporation) by reason of the 
fact that such person is or was a director, officer, employee or agent of the 
corporation, or who is or was serving at the request of the corporation as a 
director, officer, employee or agent or another corporation, partnership, 
joint venture, trust or other enterprise, against expenses (including 
attorneys' fees), judgments, fines and amounts paid in settlement actually 
and reasonably incurred by such person in connection with such action, suit 
or proceeding if he acted in good faith and in a manner he reasonably 
believed to be in or not opposed to the best interests of the corporation, 
and, with respect to any criminal action or proceeding, had no reasonable 
cause to believe his or her conduct was unlawful.  The termination of any 
action, suit or proceeding by judgment or settlement, conviction or upon a 
plea of nolo contendere or its equivalent, shall not, of itself, create a 
presumption that the person did not act in good faith and in a manner which 
he or she reasonably believed to be in or not opposed to the best interests 
of the corporation, and with respect to any criminal action or proceeding, 
had reasonable cause to believe that his conduct was unlawful.

<PAGE>

     SECTION 2.  The corporation shall indemnify any person who was or is a 
party or is threatened to be made a party to any threatened, pending or 
completed action or suit by or in the right of the corporation to procure a 
judgment in its favor by reason of the fact that such person is or was a 
director, officer, employee or agent of the corporation, or is or was serving 
at the request of the corporation as a director, officer, employee or agent 
of another corporation, partnership, joint venture, trust or other enterprise 
against expenses (including attorneys' fees) actually and reasonably incurred 
by such person in connection with the defense or settlement of such action or 
suit if he or she acted in good faith and in a manner he or she reasonably 
believed to be in or not opposed to the best interests of the corporation and 
except that no indemnification shall be made in respect of any claim, issue 
or matter as to which such person shall have been adjudged to be liable for 
negligence or misconduct in the performance of his duty to the corporation 
unless and only to the extent that the court in which such action or suit was 
brought shall determine upon application that despite the adjudication of 
liability but in view of all the circumstances of the case, such person is 
fairly and reasonably entitled to indemnity for such expenses which the court 
shall deem proper.

     SECTION 3.  To the extent that a director, officer, employee, or agent 
of a corporation has been successful, on the merits or otherwise, in the 
defense of any action, suit or proceeding referred to in sections 1 and 2, or 
in defense of any claim, issue or matter therein, such person shall be 
indemnified against expenses actually and reasonably incurred by such person 
in connection therewith.

     SECTION 4.  Any indemnification under sections 1 and 2 shall be made by 
the corporation only as authorized in the specific case upon a determination 
that indemnification of the director, officer, employee or agent is proper in 
the circumstances because he or she has met the applicable standard of 
conduct set forth in sections 1 and 2.  Such determination shall be made (a) 
by the board of directors by a majority vote of a quorum consisting of 
directors who were not parties to such action, suit or proceeding, or (b) if 
such a quorum is not obtainable, or, even if obtainable, a quorum of 
disinterested directors so directs, by independent legal counsel in a written 
opinion, or (c) by the shareholders.

     SECTION 5.  Expenses incurred in defending a civil or criminal action, 
suit or proceeding may be paid by the corporation in advance of the final 
disposition of such action, suit or proceeding, as authorized by the board of 
directors in 

<PAGE>

the specific case, upon receipt of an undertaking by or on behalf of the 
director, officer, employee or agent to repay such amount, unless it shall 
ultimately be determined that he or she is entitled to be indemnified by the 
corporation as authorized in this article.

     SECTION 6.  The indemnification provided by this article shall not be 
deemed exclusive of any other rights to which those seeking indemnification 
may be entitled under any by-law, agreement, vote of shareholders or 
disinterested directors or otherwise, both as to action in his or her 
official capacity and as to action in another capacity while holding such 
office, and shall continue as to a person who has ceased to be a director, 
officer, employee or agent and shall inure to the benefit of the heirs, 
executors and administrators of such a person.

     SECTION 7.  The corporation shall have power to purchase and maintain 
insurance on behalf of any person who is or was a director, officer, employee 
or agent of the corporation, or is or was serving at the request of the 
corporation as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise against any liability 
asserted against such person and incurred by such person in any  such 
capacity, or arising out of his or her status as such, whether or not the 
corporation would have the power to indemnify such person against such 
liability under the provisions of these sections.

     SECTION 8.  If the corporation has paid indemnity or had advanced 
expenses to a director, officer, employee or agent, the corporation shall 
report the indemnification or advance in writing to the shareholders with or 
before the notice of the next shareholders' meetings.

     SECTION 9.  References to "the corporation" shall include, in addition 
to the surviving corporation, any merging corporation, including any 
corporation having merged with a merging corporation, absorbed in a merger 
which otherwise would have lawfully been entitled to indemnify its directors, 
officers, and employees or agents.

     RE:  REGISTRATION STATEMENT ON FORM S-4

Ladies and Gentlemen:

     You have requested our opinion in connection with the above-referenced 
registration statement (the "Registration Statement") for the registration of 
up to 64,072 shares of Common Stock, $1.00 par value per share, of the 
Company (the "Shares") in connection with the Company's acquisition of 
Shipman Bancorp, Inc.

     In arriving at the opinion expressed below, we have examined the 
Registration Statement and such other documents as we have deemed necessary 
to enable us to express the opinion hereinafter set forth.  In our 
examination, we have assumed the authenticity of all documents submitted to 
us as originals, the conformity to the original documents of all documents 
submitted to us as copies, the genuineness of all signatures on documents 
reviewed by us and the legal capacity of natural persons.

     Based upon and subject to the foregoing, we are of the opinion that the 
Shares have been duly authorized and, when issued in accordance with the 
terms and conditions set forth in the Registration Statement, will be validly 
issued, fully paid and non-assessable.

     We hereby consent to the reference to our firm under the caption 
"Opinions" in the Registration Statement and to the use of this opinion as an 
exhibit to the Registration Statement.

                                   Very truly yours,

The Board of Directors
Shipman Bancorp, Inc.
111 Keating Street
Shipman, Illinois  62685

                     RE:  Tax Opinion Concerning Reorganization
            Internal Revenue Code Section 368(a)(1)(A) and 368(a)(2)(E)
                                          
Dear Members of the Board of Directors:

You have requested our opinion as to certain Federal income tax consequences of
the merger (Merger) of Shipman Acquisition Corporation (Acquisition Corp), a
wholly-owned subsidiary of Carlinville National Bank Shares, Inc. (CNB), with
and into Shipman Bancorp, Inc. (Shipman) in exchange for stock of CNB and/or
cash.

We have received and relied upon the following representations:

     A complete Agreement and Plan of Merger dated as of March 27, 1998
     (Agreement), among CNB, Acquisition Corp and Shipman.

     To the extent not inconsistent with the following representations, the
     Merger will be consummated in accordance with the Agreement, by and among
     CNB, Acquisition Corp and Shipman.

     Shipman's issued and outstanding capital stock consists of 32,035.8291
     shares of a single class of common stock, par value $10.00 per share.

     CNB is a Delaware corporation which was organized as a registered bank
     holding company under the Bank Holding Company Act of 1956 (the Act).  CNB,
     through its bank and non-bank subsidiaries, offers complete banking and
     related financial services.

     Acquisition Corp is a recently-formed Illinois corporation and a wholly
     owned subsidiary of CNB.  Acquisition Corp was organized to effect the
     proposed Merger with Shipman.  Shipman will be the surviving corporation
     upon consummation of the Merger and the name will remain unchanged. 

<PAGE>

The Board of Directors
Shipman Bancorp, Inc.

Page 2

     The fair market value of the CNB stock and other consideration, if any, to
     be received by each Shipman shareholder in the Merger will, in each
     instance, be equal to the fair market value of Shipman stock surrendered in
     exchange therefore.

<PAGE>

The Board of Directors
Shipman Bancorp, Inc.

Page 3

There is no plan or intention by the shareholders of Shipman who own one percent
or more of Shipman stock, and to the best of the knowledge of management of
Shipman, there is no plan or intention on the part of the remaining shareholders
of Shipman to sell, exchange, or otherwise dispose of a number of shares of CNB
stock received in the transaction that would reduce the Shipman shareholders'
ownership of CNB stock to a number of shares having a value, as of the date of
the transaction, of less that 50 percent of the value of all of the formerly
outstanding stock of Shipman as of the same date.  For purposes of this
representation, shares of Shipman stock exchanged for cash or for cash in lieu
of fractional shares of CNB stock will be treated as outstanding shares of
Shipman stock on the date of the transaction.  Moreover, shares of Shipman stock
and shares of CNB stock held by Shipman shareholders and otherwise sold,
redeemed or disposed of prior or subsequent to the transaction will be
considered in making this representation.

In the Merger, common shares of Shipman representing at least 70% of the
outstanding common stock of Shipman will be exchanged solely for common stock of
CNB.  For purposes of this representation, shares of Shipman common stock
exchanged for cash or other property, surrendered by dissenters or exchanged for
cash in lieu of fractional shares of CNB common stock will be treated as shares
of Shipman common stock on the date of the Merger.  Moreover, shares of Shipman
common stock and shares of CNB common stock held by Shipman shareholders and
otherwise sold, redeemed or disposed of prior to or subsequent to the Merger
will be considered as outstanding common stock of Shipman in making this
representation.

For purposes of this representation, any amounts paid by Shipman to pay its 
reorganization expenses, and all redemptions and distributions (except for 
regular, normal dividends) made by Shipman immediately before the transaction 
will be included as assets held by Shipman immediately prior to the 
transaction. All payments to Shipman shareholders who properly exercise their 
dissenters' rights will be paid by CNB and no assets of Shipman will be used 
for this purpose.

Prior to the Merger, CNB will own all of the issued and outstanding common stock
of Acquisition Corp.  Neither CNB nor Acquisition Corp will engage in any
transaction that will result in CNB's ownership in Acquisition Corp being
reduced below control within the meaning of Section 368(c) of the Internal
Revenue Code (Code).

CNB has no plan, binding commitment or intention to redeem or otherwise
reacquire any of the CNB common stock issued in the merger.  CNB has no plan or
intention to liquidate Shipman, to sell or otherwise dispose of the common stock
of Shipman, to merge Shipman with and into another corporation or to cause
Shipman to sell or otherwise dispose of any of the acquired assets of Shipman,
except for dispositions made in the ordinary course of business.

Following the Merger, Shipman will retain substantially all of its assets and
continue the historic business of Shipman.

Page 5

CNB, Acquisition Corp, Shipman and shareholders of Shipman will pay their
respective expenses, if any, incurred in connection with the Merger.

There is and will be no intercorporate indebtedness between CNB, Shipman and
Acquisition Corp that was or will be issued, acquired or settled at a discount.

Neither CNB, Shipman or Acquisition Corp is an investment company as defined in
Section's 368(a)(2)(F)(iii) or (iv) of the Code.

No party to the transaction is under the jurisdiction of a court in a Title 11,
or similar case within the meaning of Section 368(a)(3)(A) of the Code.

At the time of Merger, the fair market value and the adjusted tax basis of the
assets of Shipman will exceed the sum of Shipman's liabilities, plus the amount
of liabilities, if any, to which the assets to be acquired are subject.

No Acquisition Corp common stock will be issued in the Merger.

None of the compensation to be received by any shareholder employees of Shipman
is separate consideration for, or allocable to, any of their shares of Shipman
common stock.  CNB common stock received by any shareholder/employee of Shipman
is not separate consideration for, or allocable to, any employment agreement or
other compensation owed to such shareholder/employee.

CNB does not own, directly or indirectly, nor has it owned, directly or
indirectly, in the past five years, any Shipman common stock.

No dividends will be paid by Shipman before the consummation of the Merger,
other than regular periodic dividends, consistent in amount and in effect with
prior dividend distributions.

Shipman has, and on the date of the proposed transaction will have, no
outstanding warrants, options, convertible securities or any type of rights
pursuant to which any person could acquire common stock in Shipman that would
affect CNB as defined in Section 368(c) of the Code.

We have assumed all of the representations contained herein are true and
correct.  We have relied upon the opinion of Gerrish & McCreary, P.C., counsel
to Shipman, and upon which such counsel has expressly stated we are entitled to
rely, that the Merger qualifies under applicable state law.

OPINION

Based on an understanding of the facts, our reliance upon the opinion of CNB's
counsel with respect to the qualification of the Merger, the representations
made to us and assumptions stated herein, our review of the relevant sections of
the Internal Revenue Code of 1986, as amended, the regulations promulgated
thereunder, and cases, rulings and other authorities, it is our opinion that the
transaction will be treated as follows for tax purposes:

     The Merger of Shipman and Acquisition Corp will qualify as a reorganization
     within the meaning of Section 368(a)(1)(A) and 368(a)(2)(E) of the Code,
     and CNB, Shipman and Acquisition Corp will each be a "party to a
     reorganization" within the meaning of Section 368(b).

     No gain or loss will be recognized by Shipman, CNB, and Acquisition Corp as
     a result of the Merger (Code Sections 361(a), 357(a) and Rev. Rul. 57-278).

     The tax basis of the assets of Shipman will be, in each case, the same as
     the basis of such assets in the hands of Shipman immediately before the
     transaction (Code Section 362(b)).

     The holding period of Shipman's assets will include the holding period of
     such assets by Shipman immediately before the Merger (Code Section
     1223(2)).

     For Shipman shareholders who solely receive CNB common stock in exchange
     for their Shipman common stock, the tax basis in the new common shares will
     be the same as the tax basis of Shipman common stock surrendered in
     exchange therefore (Code Section 358(a)(1)).

     The holding period of CNB common stock received by shareholders of Shipman
     will include the holding period for Shipman common shares surrendered in
     the Merger, provided that Shipman common shares surrendered were held as
     capital assets in the hands of Shipman shareholders at the time of the
     Merger (Code Section 1223(1)).

     In the exchange of stock, no gain or loss will be recognized by the
     shareholders of Shipman upon the receipt of solely CNB stock (Code Section
     354(a)(1)).

     Cash received by a shareholder in exchange for Shipman common stock will be
     treated as a distribution in redemption, subject to Section 302 of the
     Code.  If such Shipman shareholder subsequently holds no common stock of
     CNB directly, nor is deemed to own any such common stock under the
     constructive ownership rules of Section 318(a), the redemption will be a
     complete termination of the shareholder's interest within the meaning of
     Section 302(b)(3) of the Code and will be treated as a distribution in full
     payment in exchange for the common stock redeemed, as provided in Section
     302(a).  Accordingly, such shareholder will recognize gain or loss under
     Section 1001 measured by the difference between the cash received and the
     adjusted basis of the surrendered common stock.  Provided that the Shipman
     stock is a capital asset in the hands of the Shipman shareholders, the gain
     or loss to be recognized will be capital gain or loss.  If the shareholder
     does not meet the requirements of 302(b), cash received may be treated as a
     taxable dividend and will be subject to ordinary income tax rates (Rev.
     Rul. 93-61, I.R.B. 1993-30, Rev. Proc. 77-41, 1977-2 C.B. 574; Rev. Rul.
     66-365, 1966-2 C.B. 116).

Our opinion is based on the representations made to us and the assumptions
stated herein.  If any of the facts, representations or assumptions are
determined to be incorrect, our opinion may be adversely affected.  We express
no opinion as to the accuracy of the facts, representations and assumptions
stated herein.  We express no opinion regarding any other Federal, state, local,
foreign or other matter not contained in this letter.

Our opinion is based upon existing law, Treasury regulations, and administrative
and judicial interpretations of the law and regulations.  Administrative
positions of the Internal Revenue Service contained in Revenue Rulings and
Revenue Procedures and judicial decisions are subject to change, either
prospectively or retroactively.  We undertake no obligation to update this
opinion for changes in facts or law occurring subsequent to the date of this
opinion.  This opinion is not binding on the Internal Revenue Service or the
courts.

Our opinion is furnished solely for the benefit of the Board of Directors of
Shipman Bancorp, Inc. and is not to be released or distributed to any other
person without our prior written consent.  We consent to the filing of this
opinion as an exhibit to the Registration Statement on Form S-4 filed by
Carlinville National Bank Shares, Inc. with the Securities and Exchange
Commission for the purpose of registering securities under the Securities Act of
1933, as amended.

                              [__________], 1998

To the Stockholders of Shipman Bancorp, Inc.:

      You are cordially invited to attend a Special Meeting of Stockholders 
of Shipman to be held at     [__:__ _.m.], local time, on [__________], 1998, 
at [_________________________________] (the "Meeting").

     At the Meeting, stockholders will be asked to consider and vote upon the 
approval and adoption of an Agreement and Plan of Merger, dated March 27, 
1998 (the "Merger Agreement"), among Shipman Bancorp, Inc. ("Shipman"), 
Carlinville National Bank Shares, Inc., a Delaware corporation ("CNB"), and 
Shipman Acquisition Corporation, an Illinois corporation and a wholly owned 
subsidiary of CNB ("Acquisition Corp").

     Pursuant to the Merger Agreement, Acquisition Corp will merge with and 
into Shipman (the "Merger") and the separate existence of Shipman will cease 
and Shipman will become a wholly-owned subsidiary of CNB.  If the Merger 
Agreement is approved by the Shipman stockholders, and the Merger becomes 
effective, each outstanding share of the common stock of Shipman (except for 
shares held by dissenting Shipman stockholders) will be converted into the 
right to receive cash in the amount of $190 or two shares of the common stock 
of CNB.  The consummation of the Merger is subject to the satisfaction of 
certain conditions notwithstanding the approval of the Merger by the Shipman 
stockholders at the Meeting.

     After carefully considering the Merger, the Merger Agreement and the 
benefits which will result to the Shipman stockholders, the Board of 
Directors of Shipman has determined that the Merger is in the best interests 
of the stockholders and urges that you vote in favor of the Merger Agreement.

     Your vote is important.  Approval of the proposed Merger requires the 
affirmative vote of the holders of at least two thirds of the issued and 
outstanding shares of the common stock of Shipman.  Whether or not you expect 
to attend the meeting in person, please sign and date the accompanying Proxy 
and mail it promptly in the enclosed envelope.

                                   Sincerely,


                                   James H. Frank

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

     NOTICE IS HEREBY GIVEN that a Special Meeting of the Stockholders of 
Shipman Bancorp, Inc. (the "Meeting") will be held at [__:__ _.m.], local 
time, for the following purposes:

     1.   To consider and vote upon a proposal to approve and adopt an 
Agreement and Plan of Merger, dated March 27, 1998 (the "Merger Agreement"), 
among Shipman Bancorp, Inc. ("Shipman"), Carlinville National Bank Shares, 
Inc., a Delaware corporation ("CNB"), and Shipman Acquisition Corporation, an 
Illinois corporation and a wholly owned subsidiary of CNB ("Acquisition 
Corp"), which provides for the merger of Acquisition Corp with and into 
Shipman (the "Merger") and the conversion, upon the consummation of the 
Merger, of each outstanding share of the common stock of Shipman (except for 
shares held by dissenting Shipman Stockholders) into the right to receive 
cash in the amount of $190 or two shares of the common stock of CNB; and

     2.   To transact such other business as may properly come before the 
Meeting or any adjournments or postponements thereof.

     The Board of Directors of Shipman has fixed the close of business on 
[__________], 1998, as the record date for the determination of Shipman 
stockholders entitled to notice of, and to vote at, the Meeting and any 
adjournments or postponements thereof.  Only stockholders of record at the 
close of business on the record date will be entitled to receive notice of, 
and to vote at, the Meeting and any adjournments or postponements thereof.

     Each Shipman stockholder has the right to dissent and receive the fair 
value of the stockholder's shares if the stockholder delivers to Shipman 
before the vote is taken at the Meeting a written demand for payment for the 
shares, does not vote in favor of the Merger and complies with the procedures 
set forth in Sections 11.65 and 11.70 of the Illinois Business Corporation 
Act of 1983, as amended, which are set forth in Appendix C to the Proxy 
Statement-Prospectus .  It is a condition to CNB's obligation to consummate 
the Merger that dissenters' appraisal rights not be perfected with respect to 
more than 10% of the outstanding common stock of Shipman.

                                   By Order of The Board of Directors,

                                   James H. Frank
                                   Chairman of the Board
