                          MID STATES BANCSHARES, INC.


                                            , 1994


Dear Fellow Shareholder:

   
You are cordially invited to attend a Special Meeting of Shareholders of Mid 
States Bancshares, Inc. ("MID STATES") to be held at 501 15th Street, Moline, 
Illinois on                , April   , 1994, at 10:00 a.m., local time.

The purpose of the meeting is to consider and vote upon approval of an 
Agreement and Plan of Merger dated May 25, 1993, as amended February 22, 1994 
and March 28, 1994 (the "Merger Agreement"), pursuant to which MID STATES will 
merge with and into a wholly owned subsidiary of BANC ONE CORPORATION.  In the 
merger each outstanding share of MID STATES Common Stock will be converted into 
2.917 shares of BANC ONE Common Stock, as described more fully in the 
accompanying Prospectus and Proxy Statement.

Your Board of Directors believes that the terms of the Merger Agreement, as 
amended, are in the best interests of MID STATES shareholders, will provide 
significant value to all MID STATES shareholders, and will enable holders of 
MID STATES Common Stock to participate in the expanded opportunities for growth 
that the merger will make possible.

Given the lengthy delay in submitting the Merger Agreement to the shareholders, 
a brief history of the proposed merger follows:  BANC ONE and MID STATES 
announced the Merger Agreement on May 25, 1993.  BANC ONE and MID STATES 
immediately began the process of obtaining necessary approvals.  All regulatory 
approvals required prior to the merger were obtained.  A special meeting of 
shareholders of MID STATES was originally scheduled for January 26, 1994 for 
the purpose of MID STATES shareholders approval of the Merger Agreement.  The 
Board of Directors of MID STATES had unanimously recommended the merger to the 
shareholders and urged them to vote in favor of the proposed merger in the 
prospectus and proxy statement dated December 21, 1993 (the "December 21 
Proxy") delivered to the shareholders of MID STATES in connection with that 
special meeting.

However, the Merger Agreement contained a provision permitting MID STATES to 
terminate the Merger Agreement if during the January 11-24, 1994 evaluation 
period (during which the market price for BANC ONE's common stock was 
averaged), the average price of BANC ONE Common Stock (the "Evaluation Period 
Price") was below $37.82, which is a merger value equivalent of $102.96 per 
share of MID STATES Common Stock.  This right to terminate is the so-called 
"walk-away" provision.  In fact, the Evaluation Period Price was $33.43.  The 
Board of Directors had stated in the December 21 Proxy that it did not intend 
to waive the "walk-away" provision.  Also, Donaldson, Lufkin & Jenrette 
Securities Corporation ("DLJ"), MID STATES' financial advisor, had, at the 
Board of Directors' request, specifically excluded from their fairness opinion 
dated December 21 1993 (the "December 21 opinion") the situation where the 
Evaluation Period Price was below $37.82.  The December 21 opinion was a major 
supporting factor for the Board of Director's original recommendation in favor 
of the merger.

During the period immediately prior to January 26, DLJ on behalf of MID STATES 
requested that BANC ONE increase the exchange ratio so as to bring the value of 
BANC ONE shares to be received in the merger in respect to each share of MID 
STATES Common Stock to or above $102.96 at the closing.  BANC ONE declined, but 
indicated a strong desire to consummate the merger and a willingness to 
negotiate terms other than the exchange ratio.  On January 26, 1994, the Board 
of Director's chose to cancel the scheduled special meeting without voting on 
the merger so as to allow for further discussion with BANC ONE with a view to 
finding a basis for completion of the transaction.  This was done because the 
Board of Directors was, and is, committed to the proposition that a merger with 
BANC ONE is in the best interest of MID STATES, its shareholders, employees, 
customers and depositors, as well as the Quad Cities community.  For these 
reasons and the reasons set forth below and on page      of the accompanying 
Prospectus and Proxy Statement under "Merger Recommendations and Reasons for 
Transaction" (the "pertinent reasons") the Board of Directors chose not to 
exercise the walk-away provision at such time.  MID STATES shareholders were 
informed of these events in a letter dated January 26, 1994.

On February 22, 1994 BANC ONE and MID STATES entered into the First Amendment 
to the Merger Agreement.  The First Amendment contains the following provisions:

1.  MID STATES agreed that it would, conditionally, resolicit the MID STATES 
    shareholders to approve the merger and in doing so would inform the 
    shareholders that the MID STATES Board of Directors intends to proceed with 
    the merger even if the BANC ONE share value equivalent is less than 
    $102.96.  The relevant conditions are: (a) that MID STATES' financial 
    advisors opine that the exchange ratio is fair to the MID STATES 
    shareholders from a financial point of view, disregarding the fact that the 
    BANC ONE Evaluation Period Price was below $37.82 ($102.96 per MID STATES 
    share of Common Stock merger value equivalent) as described above and might 
    be below such amount at the closing [MID STATES intended to obtain a new 
    fairness opinion from DLJ and to obtain a concurring "second opinion" from 
    The Chicago Corporation ("TCC"), an investment banking firm, as to the 
    fairness of the exchange ratio/merger consideration to the MID STATES 
    shareholders]; (b) that these fairness opinions remain in effect at the 
    closing of the merger transaction; and (c) that the shareholders of MID 
    STATES approve the Merger Agreement with the knowledge that the Board of 
    Directors intends to  proceed with the merger on the terms and conditions 
    described above.

2.  MID STATES and BANC ONE agreed that MID STATES' right to terminate the 
    Merger Agreement based upon the walk-away provision was amended so that MID 
    STATES could unilaterally terminate the Merger Agreement if it could not 
    obtain the necessary fairness opinions or any other cause made it probable 
    that the merger could not be consummated prior to May 1, 1994, the 
    "outside" date for completion of the Merger Agreement.

3.  BANC ONE agreed to reimburse MID STATES for one-half of its out-of-pocket 
    expenses (legal, financial advisory, accounting, etc.) incurred after 
    January 25, 1994 in connection with the merger -- whether or not the 
    transaction is consummated.


During mid-February DLJ on behalf of MID STATES began discussions with BANC ONE 
concerning the need for BANC ONE to increase the exchange ratio/merger 
consideration so as to permit DLJ and TCC to issue their fairness opinions.  
During this time, the Board of Directors determined that, based on the 
pertinent reasons, if the merger with BANC ONE could not be accomplished at 
this time, the best course for MID STATES currently is to remain independent.  
Therefore, the MID STATES' Board instructed management and DLJ not to solicit 
or respond to inquiries from other possible interested parties for MID STATES, 
including the party from which MID STATES received an indication of interest 
for a possible merger with MID STATES in March, 1993.

On March 11, 1994 BANC ONE offered to increase the exchange ratio from 2.7225 
BANC ONE common shares (as adjusted to account for BANC ONE's 10% stock 
dividend of March 4, 1994) for each share of Common Stock of MID STATES to 
2.917 shares.  BANC ONE and MID STATES further agreed to extend the "outside" 
termination date under the Merger Agreement to July 1, 1994 so as to enable 
sufficient time to resolicit the shareholders of MID STATES.  At a MID STATES 
Board of Director's Meeting on March 28, 1994 the Board of Directors agreed to 
ratify the Second Amendment to the Merger Agreement which encompassed these two 
terms and received the fairness opinions of its two financial advisors, DLJ and 
TCC.  Based upon these reports and the new increased exchanged ratio, the Board 
of Directors once again, unanimously, recommends the merger to the shareholders 
and urges shareholder approval and the adoption of the Merger Agreement, as 
amended.

The Board of Directors has set April   , 1994 as the date of the Special 
Meeting of Shareholders at which the Merger Agreement, as amended, will be 
considered and voted upon by the shareholders.  Due to the lapse of time 
between the originally scheduled special meeting of shareholders and this newly 
scheduled Special Meeting, the Board of Directors has set a new record date 
of              , 1994.  All shareholders of record as of the close of business 
on such date shall be entitled to notice of and to vote at the Special Meeting 
of Shareholders.

Additional information is contained in the accompanying Prospectus and Proxy 
Statement which I urge you to read carefully.

Your Board of Directors unanimously recommends that you vote in favor of the 
approval of the Merger Agreement, as amended.

Please indicate your voting instructions, sign and date the enclosed Proxy and 
mail it promptly in the return envelope provided.  Whether or not you plan to 
attend the meeting, it is important that you return the enclosed Proxy so that 
your shares of MID STATES Common Stock are voted.
    

                                              Sincerely,

This Prospectus and Proxy Statement (the "Prospectus" or "Prospectus and Proxy 
Statement") relates to the proposed merger of Mid States Bancshares, Inc. ("MID 
STATES") with and into Banc One Illinois Corporation ("Banc One Illinois"), a 
wholly owned subsidiary of BANC ONE CORPORATION ("BANC ONE").  If the proposed 
merger (the "Merger") is consummated, each outstanding share of MID STATES 
Common Stock, par value $5.00 per share ("MID STATES Common Stock"), will be 
converted into    2.917     shares of BANC ONE Common Stock, no par value 
("BANC ONE Common Stock").  See "MERGER--Exchange    Ratio    ."  The Merger is 
subject to the approval of not less than a majority of the holders of the 
outstanding shares of MID STATES Common Stock entitled to vote thereon and to 
the satisfaction of certain other conditions, including obtaining various 
regulatory approvals.  This Prospectus and Proxy Statement does not cover any 
resales of BANC ONE Common Stock received by affiliates of MID STATES upon 
consummation of the Merger, and no person is authorized to make use of 
this Prospectus and Proxy Statement in connection with any such resale.

BANC ONE Common Stock is traded on the New York Stock Exchange.  The closing

                                  INTRODUCTION

This Prospectus and Proxy Statement (the "Prospectus" or "Prospectus and Proxy 
Statement") is furnished in connection with the solicitation of proxies by the 
Board of Directors of Mid States Bancshares, Inc. ("MID STATES") a registered 
bank holding company headquartered in Moline, Illinois, to be voted at the 
Special Meeting of Shareholders of MID STATES to be held on                , 
1994 for the purpose of considering and taking action upon a proposal to merge 
(the "Merger") MID STATES with and into Banc One Illinois Corporation ("Banc 
One Illinois"), a wholly owned subsidiary of BANC ONE CORPORATION ("BANC ONE"), 
a registered multi-bank holding company headquartered in Columbus, Ohio.  This 
proposal is in accordance with the Agreement and Plan of Merger dated May 25, 
1993 by and among MID STATES, Banc One Illinois and BANC ONE   , as amended on 
February 22, 1994 and March 25, 1994     (the "Merger Agreement").

The principal office of BANC ONE is 100 East Broad Street, Columbus, Ohio 43271 
and its telephone number is 614/248-5944.  The principal office of MID STATES 
is 501 15th Street, Moline, Illinois  61265-2180 and its telephone number is 
309/757-8400.

This Prospectus and the form of proxy are being mailed to the shareholders of 
MID STATES for the first time on or about                , 1994.

Mid States Bancshares, Inc.

MID STATES is a bank holding company incorporated under the laws of the state 
of Delaware in Moline, Illinois which owns all of the outstanding stock of the 
First National Bank of Moline, a national banking association with its main 
office located in Moline, Illinois ("First National", the "Bank" or the 
"Subsidiary").  The Bank operates three offices in Moline, Illinois.  As of 
   December 31,     1993, MID STATES had total assets of approximately    $192 
million     and the Bank had deposits of approximately    $163 million    .  
See "INFORMATION ABOUT MID STATES BANCSHARES, INC."

BANC ONE CORPORATION

BANC ONE is a multi-bank holding company incorporated under the laws of the 
State of Ohio which as of    December 31,     1993 owned all of the 
outstanding stock of one Arizona, two Kentucky, six Illinois, one Texas, 
four Michigan, eight Indiana, fourteen Wisconsin, one California, seven 
Colorado, eighteen Ohio, one Utah,    two Oklahoma     and sixteen West 
Virginia commercial banks.  These banks operate more than    1,300     offices 
in this thirteen-state area and, at    December 31, 1993    , BANC ONE, its 
affiliate banks and its non-bank subsidiaries had total assets of approximately 
   $79.9 billion     and total deposits of approximately    $60.9 billion    .  
Banc One Illinois, a direct subsidiary of BANC ONE, is the direct parent 
of BANC ONE's commercial banks situated in the State of Illinois.  See 
"INFORMATION ABOUT BANC ONE CORPORATION", which includes information 
about pending acquisitions.

                           SUMMARY OF THE TRANSACTION


Terms of Agreement and Exchange Rate

Upon the Merger becoming effective, each of the outstanding shares of MID 
STATES Common Stock, par value $5.00 per share ("MID STATES Common Stock"), 
will be converted into    2.917     shares of BANC ONE Common Stock, no par 
value ("BANC ONE Common Stock") (the "Exchange    Ratio    ").  Upon 
consummation of the Merger, MID STATES will be merged with and into Banc One 
Illinois and the separate corporate existence of MID STATES will cease.  
Banc One Illinois, as the surviving corporation in the Merger and a wholly 
owned subsidiary of BANC ONE, will continue operations under the name Banc One 
Illinois Corporation.  See "MERGER--Exchange    Ratio    ."

Management After the Merger

Banc One Illinois will operate with Banc One Illinois' current officers and 
employees, with its principal place of business in Springfield, Illinois.  Banc 
One Illinois' current directors will serve as the directors of the surviving 
corporation following the Merger.  It is anticipated that following the Merger, 
First National will operate under the name of Bank One, Quad Cities, National 
Association (the "Resulting Bank").  The Resulting Bank will conduct its 
banking operations at First National's present offices.

The Resulting Bank, as a BANC ONE affiliate after the Merger, will operate 
under BANC ONE's operating philosophy whereby it will have autonomy to match 
its products and services to the needs of its local communities.  BANC ONE bank 
affiliates have authority to make decisions locally in "people-related" matters 
such as lending, personnel, charitable contributions and other community and 
related matters, relying upon BANC ONE and its state holding companies for 
"paper and computer related" matters such as assistance in accounting, certain 
legal matters, investment portfolio management, regulatory compliance, data 
processing and other matters which are generally best performed by specialists 
on a centralized basis.

Tax Consequences

   As a condition to the Merger,     MID STATES and BANC ONE    received     
an opinion dated    April 20, 1994     from Vedder, Price, Kaufman & Kammholz 
substantially to the effect that, among other things, no gain or loss will be 
recognized by MID STATES' shareholders for federal income tax purposes as a 
result of the exchange of their MID STATES Common Stock for BANC ONE Common 
Stock in the Merger, except to the extent that cash is received in lieu 
of fractional shares of BANC ONE Common Stock or pursuant to the exercise of 
dissenters' rights.  Certain tax consequences of the proposed transaction to 
shareholders of MID STATES are summarized under "MERGER--Federal Income Tax 
Consequences."

Vote Required

Not less than a majority of the outstanding shares of MID STATES Common Stock 
entitled to vote thereon must vote in favor of the approval of the Merger 
Agreement in order for the transaction to be approved.  The directors and 
executive officers of MID STATES and their affiliates and associates are 
entitled to vote approximately    160,000     shares, or approximately 
   51%     of the outstanding shares of MID STATES Common Stock.  Although no 
agreements are in effect, it is currently anticipated that each such holder 
will vote his or her shares for approval of the Merger Agreement.  It is 
not necessary for the shareholders of BANC ONE to approve the merger proposal.  
However, BANC ONE, as the sole shareholder of Banc One Illinois, has 
approved the Merger and the Merger Agreement.  For information concerning 
voting by shareholders of MID STATES on the proposed Merger see "MERGER--
General" and "VOTING AND MANAGEMENT INFORMATION--Voting."

Opinions of Investment Bankers

Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ")    and The Chicago 
Corporation ('TCC") have each delivered a    written opinion to the MID STATES' 
Board of Directors (the "MID STATES Board") to the effect that, as of the date 
of this Prospectus and Proxy Statement, the Exchange    Ratio     provided 
for in the Merger Agreement is fair to the holders of MID STATES Common Stock 
from a financial point of view.  Copies of the opinions of DLJ    and TCC, each 
    dated as of the date of this Prospectus and Proxy Statement   , are    
attached hereto    as Exhibit A and Exhibit B, respectively.    

   These opinions     should be read in    their     entirety for a 
description of the procedures followed, assumptions and qualifications made, 
matters considered and limitations as to the scope    thereof.      See 
"MERGER -- Opinion   s     of Investment Banker   s    ."

Rights of Dissenting Shareholders

Under Delaware law, certain rights are available to a shareholder of MID STATES 
who does not vote his or her shares in favor of the Merger and delivers to MID 
STATES, before the vote is taken, written notice of intent to demand payment 
for his or her MID STATES Common Stock if the Merger is consummated.  See 
"VOTING AND MANAGEMENT INFORMATION--Rights of Dissenting Shareholders."

Differences in Shareholder Rights

There are differences between the rights of MID STATES shareholders and BANC 
ONE shareholders.  Both Ohio law and BANC ONE's Amended Articles of 
Incorporation contain "control share acquisition" provisions which mandate 
certain procedures and shareholder consents to approve certain share 
acquisitions.  In addition, under Ohio law, in evaluating an acquisition 
proposal, directors of an Ohio corporation such as BANC ONE are permitted, in 
determining whether any matter is in the best interest of the corporation, to 
take into consideration the interests of the corporation's employees, 
suppliers, creditors and customers, the economy and community and societal 
considerations in the interest of the corporation and its shareholders.  The 
Delaware General Corporation Law (the "DGCL") does not contain any similar 
provisions, nor does MID STATES' Amended and Restated Certificate of 
Incorporation ("MID STATES' Certificate").  MID STATES' Certificate does, 
however, require approval of certain interested shareholder transactions by not 
less than 75% of MID STATES' outstanding shares entitled to vote, unless 
certain alternative conditions are met, one of which is approval of such 
transaction by two-thirds of MID STATES' directors.  BANC ONE's Articles also 
contain a so-called "fair price" provision which mandates certain procedures 
and approvals for a business combination.  MID STATES' Certificate contains a 
price protection provision.  See "COMPARATIVE RIGHTS OF SHAREHOLDERS--Special 
Voting Requirements for Certain Transactions."  In addition, both Ohio law and 
the DGCL contain provisions prohibiting certain business combinations between 
corporations and "Interested Shareholders."  The DGCL does not contain a 
so-called "fair price" provision.  The effect of the supermajority and fair 
price provisions contained in BANC ONE's Articles may be to discourage certain 
potential business combinations which some shareholders may believe to be in 
their best interests and to make more difficult management changes which might 
occur if the potential business combination were successful.  See "COMPARATIVE 
RIGHTS OF SHAREHOLDERS-- Comparisons of BANC ONE Common Stock and MID STATES 
Common Stock."

The cumulative voting system is used in the election of MID STATES' Board of 
Directors.  Cumulative voting is not used in the election of BANC ONE's Board 
of Directors.  See "COMPARATIVE RIGHTS OF SHAREHOLDERS--Comparison of BANC ONE 
Common Stock and MID STATES' Common Stock."

Regulatory Approvals

In order for the proposed transaction to be consummated, approval of BANC ONE's 
acquisition of MID STATES must be obtained from the Board of Governors of the 
Federal Reserve System (the "Federal Reserve") and the Illinois Commissioner of 
Banks and Trust Companies (the "Illinois Commissioner").  Both of these 
regulatory approvals have been received.

Conditions; Termination

Consummation of the Merger is also subject to satisfaction or waiver of various 
conditions, including compliance with respective covenants and confirmation of 
respective representations and warranties, the absence of any material adverse 
change in the financial condition or business of MID STATES or BANC ONE, the 
fulfillment of certain earnings tests and other matters.  MID STATES, by action 
of its Board of Directors, may elect to terminate the Merger Agreement, whether 
before or after approval of the Merger by the shareholders of MID STATES, by 
giving three (3) days written notice of such election to BANC ONE.  The Merger 
Agreement provides that either party may abandon the Merger if it is not 
consummated on or before July 1, 1994.  See "MERGER- Conditions to the Merger" 
for a more complete discussion of the conditions to consummation of the Merger.

       income from continuing

                      THE SPECIAL MEETING OF SHAREHOLDERS


This Prospectus and Proxy Statement is being furnished to the shareholders of 
MID STATES in connection with the solicitation of proxies by the MID STATES 
Board for use at MID STATES' Special Meeting of Shareholders and at any 
adjournment or adjournments thereof (the "Special Meeting").  The Special 
Meeting of Shareholders of MID STATES will be held on                , 1994, at 
10:00 a.m., local time at 501 15th Street, Moline, Illinois.

Purpose of the Special Meeting of Shareholders

At the Special Meeting, the holders of MID STATES Common Stock will vote on the 
approval of the Merger Agreement.

Record Dates and Voting Rights

The MID STATES Board has fixed the close of business on             , 1994,     
as the record date for determination of shareholders entitled to notice of and 
to vote at the Special Meeting.  As of the record date, MID STATES had 
outstanding and entitled to vote             shares of MID STATES Common 
Stock.  Each share of MID STATES Common Stock is entitled to one vote.  The 
Merger Agreement must be approved by a majority of MID STATES' shareholders.

Votes, whether in person or by proxy, will be counted and tabulated by 
inspectors appointed by MID STATES.  Abstentions and broker non-votes will not 
be counted as votes either "for" or "against" any matters coming before the 
Special Meeting, however, pursuant to Delaware law, such abstentions and broker 
non-votes will be counted toward determining a quorum.  In accordance with 
Delaware law and MID STATES' Certificate and Bylaws, such abstentions have the 
effect of a "no" vote since state law requires the Merger Agreement to be 
authorized and approved by the affirmative vote of not less than a majority of 
the MID STATES Common Stock entitled to vote, rather than a majority of those 
shares actually voting.

Proxies

Proxies for use at the Special Meeting accompany this Proxy Statement.  A 
shareholder may use a proxy whether or not he or she intends to attend the 
Special Meeting in person.  The proxy may be revoked in writing by the person 
giving it at any time before it is exercised by notice to the Secretary of MID 
STATES, by submitting a later dated proxy or by attending and voting in person 
at the Special Meeting.  All proxies validly submitted and not revoked will be 
voted in the manner specified therein.  IF NO SPECIFICATION IS MADE, THE 
PROXIES WILL BE VOTED IN FAVOR OF APPROVAL OF THE MERGER AGREEMENT.  The MID 
STATES Board is not aware of any other matters which may be presented for 
action at the Special Meeting, but if other matters do properly come before the 
meeting it is intended that the shares represented by the accompanying proxy 
will be voted by the persons named in the proxy in accordance with their best 
judgment.  The shares represented by the accompanying proxy may not be voted to 
adjourn the Special Meeting of Shareholders for the purpose of soliciting 
additional votes to approve the Merger.

Solicitation of proxies will be made in person, by mail, or by telephone or 
telegraph by present and former directors, officers and employees of MID STATES 
and First National for which no additional compensation will be paid.  MID 
STATES will bear the cost of solicitation of proxies from its shareholders and 
may reimburse brokers and others for their expenses in forwarding solicitation 
material to beneficial owners of its voting stock.

MID STATES held its 1993 Annual Meeting of Shareholders on April 20, 1993.  
   No date has been set for the 1994 Annual Meeting on the assumption that 
the Merger will be consummated.    

                                     MERGER

The information in this Prospectus and Proxy Statement concerning the terms of 
the Merger is a summary only and is qualified in its entirety by reference to 
the Merger Agreement   , as amended,     which is attached as an exhibit to the 
Registration Statement filed by BANC ONE with the Commission in connection with 
the Merger and which is incorporated herein by reference.  See "Incorporation 
by Reference" for the procedure for obtaining a copy of the Merger Agreement 
   and the amendments thereto.    

General

The Merger Agreement provides for the Merger of MID STATES with and into Banc 
One Illinois.  As a result of the Merger, First National will become a 
subsidiary of BANC ONE and Banc One Illinois.  Upon the effectiveness of the 
Merger (the "Effective Time") each of the outstanding shares of MID STATES 
Common Stock will be converted into 2.917 shares of BANC ONE Common Stock 
(subject to adjustments in certain circumstances), which shares of BANC ONE 
Common Stock will be issued as a result of the Merger.  See "MERGER--Exchange 
Rate."

The affirmative vote of a majority of the outstanding shares of MID STATES 
Common Stock entitled to vote at the Special Meeting is required in order to 
approve the Merger Agreement.  See "VOTING AND MANAGEMENT INFORMATION-Voting."  
However, it is a condition to BANC ONE's obligation to consummate the Merger 
that not more than 10% of the maximum aggregate total number of shares of BANC 
ONE Common Stock which could be issued by BANC ONE in the Merger are to be 
settled in cash as a result of fractional share interests or are to be issued 
to MID STATES shareholders who have asserted rights of dissenting 
shareholders.  See "VOTING AND MANAGEMENT INFORMATION-Rights of Dissenting 
Shareholders."

Subject to such shareholder approval and the satisfaction of certain conditions 
and receipt of all requisite regulatory approvals    (which have been 
obtained),     in each case as provided for in the Merger Agreement, the 
Merger will become effective upon the issuance by the Secretary of State of the 
State of Illinois of a certificate of merger with respect thereto as provided 
in applicable provisions of the Illinois Business Corporation Act of 1983, as 
amended, and filing of a Certificate of Merger with the Secretary of State 
of the State of Delaware.

The Boards of Directors of BANC ONE, Banc One Illinois and MID STATES have 
approved the Merger Agreement.  BANC ONE, as the sole shareholder of Banc One 
Illinois, has approved the Merger Agreement.  Approval of the Merger Agreement 
by the shareholders of BANC ONE is not required for consummation of the Merger.

Exchange    Ratio    

At the Effective Time, stock issued by reason of the Merger will be allocated 
to the shareholders of record of MID STATES as of the Effective Time with such 
shares of BANC ONE Common Stock to be equal to the number of shares of MID 
STATES Common Stock outstanding immediately prior to the Effective Time 
multiplied by    2.917.    

Operations After the Merger

Upon the consummation of the Merger, MID STATES will be merged into Banc One 
Illinois and the separate corporate existence of MID STATES will cease.  Banc 
One Illinois, as the surviving corporation in the Merger and a wholly owned 
subsidiary of BANC ONE, will continue operations under the name "Banc One 
Illinois Corporation" and  will operate with Banc One Illinois' current 
officers and employees, with its principal place of business at Springfield, 
Illinois.  Banc One Illinois' current directors will serve as the directors of 
the surviving corporation following the Merger.  Following the Merger, the Bank 
will change its name to Bank One, Quad Cities, N.A. and the present directors, 
officers and employees of the Bank will continue in those same capacities.  The 
Bank will conduct its banking operations at its present offices.

The Bank, as a BANC ONE affiliate after the Merger, will operate under BANC 
ONE's operating philosophy whereby it will have autonomy to match its products 
and services to the needs of its local communities.  Similarly, BANC ONE bank 
affiliates have authority to make decisions locally in "people-related" matters 
such as lending, personnel, charitable contributions and other community and 
related matters, relying upon BANC ONE and its state holding companies for 
"paper and computer related" matters such as assistance in accounting, certain 
legal matters, investment portfolio management, regulatory compliance, data 
processing and other matters which are generally best performed by specialists 
on a centralized basis.

Background of Transaction

On April 6, 1992, Mr. Thomas H. Robinson, President and CEO of MID STATES, and 
Mr. Richard Bishop, former President, CEO and director of MID STATES, met 
informally with representatives of BANC ONE.  At the meeting, initiated by BANC 
ONE, BANC ONE expressed an interest in pursuing discussions regarding a 
possible affiliation with MID STATES.  As a result of this initial meeting, 
Messrs. Bishop and Robinson and three principal shareholders of MID STATES 
(Messrs. John C. Pryor, James T. McLaughlin and Robert L. Seiffert) met with 
representatives of BANC ONE on June 16, 1992.

In July, 1992, representatives of BANC ONE again approached MID STATES 
regarding a possible affiliation and indicated an interest in meeting with the 
entire Board of Directors.  As a result, on July 20, 1992, representatives of 
BANC ONE made a presentation to the entire Board of Directors regarding 
BANC ONE and an affiliation between BANC ONE and MID STATES.

As from time to time MID STATES has received similar informal inquiries 
regarding possible affiliation, MID STATES' Board of Directors began discussing 
long-term strategic issues, including the possible sale of MID STATES, as well 
as MID STATES continuing to remain independent.  In doing so, the Board 
consulted with and retained the law firm of Vedder, Price, Kaufman & Kammholz, 
a firm with extensive experience in representing financial institutions, as 
special counsel, to assist the Board in evaluating alternatives.  Vedder, 
Price, Kaufman & Kammholz has represented MID STATES on a special counsel basis 
for a number of years.  On September 21, 1992, the Board formed the Long-Range 
Strategic Planning Committee (the "Committee"), a special board committee 
consisting of Messrs. Richard M. Bishop, Daniel Churchill, James T. McLaughlin, 
Michael S. Plunkett, John C. Pryor, Thomas H. Robinson and Robert L. Seiffert, 
for the purpose of a focused study of the various alternatives available to MID 
STATES.  The members of the committee consisted of management, outside 
directors, and representatives of MID STATES' four largest stockholder groups.

Mr. Bishop resigned as a MID STATES director and Committee member in December, 
1992 as part of his previously announced retirement plans.

At the October 19, 1992 meeting of the Board of Directors, the Committee 
recommended to the Board that an investment banking firm be retained to assist 
in exploring various strategic alternatives.  At that time, the Board of 
Directors recognized that it was in the best interests of MID STATES and its 
shareholders to retain an investment banking firm to assist in evaluating 
merger proposals and to hold discussions with certain regional bank holding 
companies that might be interested in affiliating with MID STATES.

During late October, 1992, the Committee met with representatives of, and 
reviewed the services offered by, Donaldson, Lufkin & Jenrette Securities 
Corporation, a nationally recognized investment banking firm ("DLJ").  On 
November 6, 1992, MID STATES retained DLJ on the basis of, among other things, 
its perceived expertise in merger and acquisition transactions and its 
familiarity with the most likely potential merger partners for MID STATES and 
the Midwest regional banking industry.

At the November 24, 1992 Committee meeting, the Committee, after reviewing a 
list of Midwestern regional bank holding companies, identified three 
prospective acquirors to be initially contacted by DLJ regarding a potential 
affiliation with MID STATES.  In December, 1992, DLJ forwarded confidentiality 
agreements to these three regional bank holding companies, including BANC ONE, 
which had indicated an interest in pursuing further discussions with MID 
STATES.  On December 28, 1992, BANC ONE and the two Midwestern-based bank 
holding companies executed confidentiality agreements.

During February and March, 1993, MID STATES provided financial and other 
information to each of BANC ONE and the second Midwestern-based bank holding 
company ("MBHC") pursuant to the confidentiality agreements.  At such time, the 
third Midwestern-based bank holding company indicated that it was not then 
currently interested in pursuing discussions due to other strategic initiatives.

In order to assist the Board of Directors in comparing the two interested 
parties and evaluating any merger proposal that might ensue, MID STATES 
requested that the parties prepare a written discussion of their respective 
business organizations and affiliation objectives, including, without 
limitation, a written response to the following areas of inquiry posed by the 
Board of Directors:  (i) proposed purchase price or exchange ratio, including 
any price protection or other structural features on the purchase price; 
(ii) ongoing role of the existing Board of Directors; (iii) management style 
and philosophy, including those functions that would be decentralized or 
centralized subsequent to the acquisition; (iv) post-acquisition plans for 
existing employee compensation and benefits, including existing employment 
agreements; (v) principal services and capabilities offered that would inure to 
the benefit of MID STATES customers as a result of the acquisition; (vi) loan 
policy and application process and impact of transaction on the availability of 
credit to the communities served by MID STATES; (vii) expected timetable of an 
affiliation transaction; (viii) post-acquisition staffing patterns of recent 
acquisitions and intentions regarding the autonomy of MID STATES; and 
(ix) maintenance of MID STATES' strong community identification subsequent to 
the acquisition.

On March 17, 1993, BANC ONE responded to the Board's inquiry.  In addition to 
the proposed financial terms, the response indicated that BANC ONE's underlying 
philosophy with acquisition partners is the "Uncommon Partnership," which 
includes the basic tenets of autonomy, centralized support, market diversity 
and balance and emphasis on superior products and services.  The response 
further indicated that BANC ONE offered a competitive benefits package to its 
employees and looked to promote from within.  BANC ONE emphasized its 
decentralized and local autonomy approach to management, which extends to loan 
decisions, enhanced customer service through new products, consolidation of 
certain back room and other service and support functions and continued 
investment in new technology, and encouragement of its affiliates to be 
involved in their respective communities through the use of local contractors, 
service providers and businesses and emphasis on community reinvestment 
products and services.

MBHC's March 19, 1993 response to the Board's inquiry indicated that, in 
addition to the proposed financial terms, MID STATES would continue to operate 
under its existing management with certain back room and other service 
functions being merged into MBHC's existing banking operations in the Quad 
Cities area.  The response emphasized a continued commitment to the Moline 
community in the form of new products and services and expanded and enhanced 
community reinvestment activities.  As with BANC ONE, MBHC indicated that 
credit decisions and employee management decisions were delegated activities.  
The response indicated that MBHC intended to retain the current management and 
employees and that as an affiliate of MBHC, MID STATES' employees would be 
entitled to participate in training programs, career advancement opportunities 
and benefits programs.

On March 26, 1993, the Committee met with Vedder, Price, Kaufman & Kammholz and 
DLJ in Chicago to discuss the two written responses.  At the meeting, DLJ 
reviewed the financial terms of the response by each from MBHC and BANC ONE in 
detail with the Committee.  MBHC's initial indication of interest contemplated 
a fixed exchange ratio without the protection of a "walk-away" right.  A 
walk-away right permits the seller in a merger to terminate the transaction if 
the buyer's stock price falls below a stipulated benchmark.  Based on average 
trading prices of MBHC's common stock during the relevant period, MBHC's 
initial indication of interest represented a total aggregate value of 
approximately $29-$32 million.  BANC ONE's initial indication of interest, 
included a floating exchange ratio which contemplated an upper and lower 
"collar," but no "walk-away" right.  The collar would have set a minimum and 
maximum number of shares to be issued in the merger, depending on BANC ONE's 
stock price.

Each of the proposed transactions would have resulted in tax-deferred gain or 
loss to MID STATES' shareholders.  In addition, each of the indications of 
interest contained various additional terms and was subject to various 
additional conditions.

Subsequent to the discussions with DLJ, the Committee met separately with 
representatives of the two interested parties to ascertain the specifics of 
their respective indications of interest regarding an affiliation with MID 
STATES.  At the conclusion of these meetings, the Committee met again to 
evaluate the initial indications of interest.  In evaluating the indications of 
interest, Committee members expressed concern about the possible adverse impact 
on management and employees and possible diminished customer satisfaction that 
could result from an affiliation with MBHC given that MBHC would likely operate 
First National as a branch of its existing bank in the Quad Cities area at such 
time as interstate branch banking became lawful.  The Committee also noted that 
BANC ONE was more likely than MBHC to be able to offer an acceptable purchase 
price without suffering unacceptable dilution in earnings per share.  The BANC 
ONE response also offered significantly higher dividends than currently 
provided by MID STATES and the prospects for continued growth of MID STATES as 
a financial institution.  MBHC's indication of interest also offered such 
prospects.  BANC ONE's perceived intention to continue to operate MID STATES as 
an independent entity was also given consideration.  As a result of its 
evaluations, and with the assistance of DLJ, the Committee determined that BANC 
ONE was the preferred bidder due to its perceived ability to offer superior 
financial terms and the perception that from an operations, management style 
and overall business philosophy viewpoint, BANC ONE was a more attractive 
merger partner than MBHC.  DLJ was instructed to proceed with negotiations with 
BANC ONE.

On April 2, 1993, the Committee met to discuss the status of the BANC ONE 
negotiations.  After extensive discussions, the Committee instructed DLJ to 
continue negotiations.  DLJ reported back to the Committee on April 6, 1993 
with BANC ONE's final proposed exchange ratio of 2.917 and a "walk-away" right 
for MID STATES if the market price of BANC ONE's stock was below $41.60 on the 
Effective Date.  After lengthy discussion, during which DLJ presented 
information regarding comparative transactions, the Committee determined that 
it was appropriate to present the financial terms and conditions of BANC ONE's 
indication of interest to the Board of Directors with a recommendation that the 
Board vote to approve the financial terms and conditions of BANC ONE's 
indication of interest subject to negotiation of certain outstanding issues.  
During the period immediately following the April 2, 1993 Committee meeting, 
DLJ again contacted MBHC and offered it the opportunity to increase the 
financial terms of its initial indication of interest.  At such time, MBHC 
declined to do so.

A special meeting of the Board of Directors was held on April 17, 1993 to 
consider the BANC ONE merger proposal set forth in the first draft of the 
Merger Agreement dated April 13, 1993.  At such meeting, DLJ made a 
presentation to the MID STATES Board of Directors concerning the expected 
effects of the proposed affiliation with BANC ONE.  Vedder, Price, Kaufman & 
Kammholz then reviewed in detail with the Board its duties under Delaware law 
and the proposed Merger Agreement  presented by BANC ONE.  Vedder, Price, 
Kaufman & Kammholz concluded its presentation by indicating certain issues that 
required additional negotiation.  After significant discussion, the MID STATES' 
Board of Directors authorized Mr. Robinson, with the assistance of DLJ and 
Vedder, Price, Kaufman & Kammholz, to attempt to negotiate a final definitive 
agreement with BANC ONE.

On May 24, 1993, MID STATES' Board of Directors met with Vedder, Price, Kaufman 
& Kammholz and DLJ to consider the revised merger proposal and proposed form of 
Merger Agreement which had been negotiated between the parties and their 
representatives.  At the meeting, DLJ made a detailed presentation regarding 
the proposed business combination and discussed a number of valuation 
considerations followed by a detailed presentation by Vedder, Price, Kaufman & 
Kammholz discussing the proposed Merger Agreement and the results of the 
negotiations with BANC ONE's representatives.  After a presentation and 
recommendation by the Committee and receipt of an oral opinion from DLJ that 
BANC ONE's proposal was fair, from a financial point of view, to MID STATES' 
shareholders, the MID STATES' Board unanimously approved the form of Merger 
Agreement, Benefits Agreement and Separation Assistance Plan between MID STATES 
and BANC ONE and authorized its execution with such additional changes, 
modifications and amendments as were deemed necessary or appropriate by Mr. 
Robinson.

Final modifications were made to the Merger Agreement as a result of 
negotiations between legal counsel for BANC ONE and Vedder, Price, Kaufman & 
Kammholz and it was executed by the respective parties on May 25, 1993.  Prior 
to the opening of business on May 26, 1993, MID STATES and BANC ONE issued a 
joint press release announcing the execution of the Merger Agreement.

   
BANC ONE and MID STATES began the process of obtaining necessary approvals.  
All regulatory approvals required prior to the merger were obtained.  A special 
meeting of shareholders of MID STATES was originally scheduled for January 26, 
1994 for the purpose of MID STATES shareholders approval of the Merger 
Agreement.  The Board of Directors of MID STATES had unanimously recommended 
the merger to the shareholders and urged them to vote in favor of the proposed 
merger in the prospectus and proxy statement dated December 21, 1993 delivered 
to the shareholders of MID STATES in connection with that special meeting (the 
"December 21 Proxy").

However, the Merger Agreement contained a provision permitting MID STATES to 
terminate the Merger Agreement if during the January 11-24, 1994 evaluation 
period (during which the market price for BANC ONE's common stock was 
averaged), the average price of BANC ONE Common Stock (the "Evaluation Period 
Price") was below $37.82, which is a merger value equivalent of $102.96 per 
share of MID STATES Common Stock.  This right to terminate is the so-called 
"walk-away" provision.  In fact, the Evaluation Period Price was $33.43.  The 
Board of Directors had stated in the December 21 Proxy that it did not intend 
to waive the walk-away provision.  Also, DLJ had, at the Board of Director's 
request, specifically excluded from their fairness opinion dated December 21, 
1993 (the "December 21 opinion") the situation where the Evaluation Period 
Price was below $37.82.  The December 21 opinion was a major supporting factor 
for the Board of Director's original recommendation in favor of the merger.

During the period immediately prior to January 26, DLJ on behalf of MID STATES 
requested that BANC ONE increase the exchange ratio so as to bring the value of 
BANC ONE shares to be received in the merger in respect to each share of MID 
STATES Common Stock to or above $102.96 at the closing.  BANC ONE declined, but 
indicated a strong desire to consummate the merger and a willingness to 
negotiate terms other than the exchange ratio.  On January 26, 1994, the Board 
of Director's chose to cancel the scheduled special meeting without voting on 
the merger so as to allow for further discussion with BANC ONE with a view to 
finding a basis for completion of the transaction.  This was done because the 
Board of Directors was, and is, committed to the proposition that a merger with 
BANC ONE is in the best interest of MID STATES, its shareholders, employees, 
customers and depositors, as well as the Quad Cities community.  For these 
reasons and the reasons set forth below under "Merger Recommendations and 
Reasons for Transaction" (the "pertinent reasons") the Board of Directors chose 
not to exercise the walk-away provision at such time.  MID STATES shareholders 
were informed of these events in a letter dated January 26, 1994.

On February 22, 1994 BANC ONE and MID STATES entered into the First Amendment 
to the Merger Agreement.  The First Amendment contained the following 
provisions:

1.  MID STATES agreed that it would, conditionally, resolicit the MID STATES 
    shareholders to approve the merger and in doing so would inform the 
    shareholders that the MID STATES Board of Directors intends to proceed with 
    the merger even if the BANC ONE share value equivalent is less than 
    $102.96.  The relevant conditions are: (a) that MID STATES financial 
    advisors opine that the exchange ratio is fair to the MID STATES 
    shareholders from a financial point of view, disregarding the fact that the 
    BANC ONE Evaluation Period Price was below $37.82 ($102.96 per MID STATES 
    share of Common Stock merger value equivalent) as described above and might 
    be below such amount at the closing of the merger [MID STATES intended to 
    obtain a new fairness opinion from DLJ and to obtain a concurring "second 
    opinion" from The Chicago Corporation ("TCC"), an investment banking firm, 
    as to the fairness of the exchange ratio to the MID STATES shareholders]; 
    (b) that these fairness opinions remain in effect at the closing of the 
    merger; and (c) that the shareholders of MID STATES approve the Merger 
    Agreement with the knowledge that the Board of Directors intends to proceed 
    with the merger on the terms and conditions described above.

2.  MID STATES and BANC ONE agreed that MID STATES' right to terminate the 
    Merger Agreement based upon the walk-away provision was amended so that MID 
    STATES could unilaterally terminate the Merger Agreement if it could not 
    obtain the necessary fairness opinions or any other cause made it probable 
    that the merger could not be consummated prior to May 1, 1994, the "outside 
    date" for completion of the Merger Agreement.

3.  BANC ONE agreed to reimburse MID STATES for one-half of its out-of-pocket 
    expenses (legal, financial advisory, accounting, etc.) incurred after 
    January 25, 1994 in connection with the merger -- whether or not the 
    transaction is consummated.


During mid-February DLJ on behalf of MID STATES began discussions with BANC ONE 
concerning the need for BANC ONE to increase the exchange ratio/merger 
consideration so as to permit DLJ and TCC to issue their fairness opinions.  
During this time, the Board of Directors determined that, if the merger with 
BANC ONE could not be accomplished at this time, the best course for MID STATES 
currently is to remain independent.  Therefore, the MID STATES' Board 
instructed management and DLJ not to solicit or respond to inquiries from other 
possible interested parties for MID STATES, including MBHC, the party from 
which MID STATES received an indication of interest for a possible merger with 
MID STATES in March, 1993.

On March 11, 1994 BANC ONE offered to increase the exchange ratio from 2.7225 
BANC ONE common shares (as adjusted to account for BANC ONE's 10% stock 
dividend of March 4, 1994) to each share of Common Stock of MID STATES to 2.917 
shares.  BANC ONE and MID STATES further agreed to extend the termination date 
under the Merger Agreement to July 1, 1994 so as to enable sufficient time to 
resolicit the shareholders of MID STATES.  At a MID STATES Board of Director's 
Meeting on March 28, 1994 the Board of Directors agreed to ratify the Second 
Amendment to the Merger Agreement which encompassed these two new terms and 
received the fairness opinions of its two financial advisors, DLJ and TCC.  
Based upon these reports and the increased exchanged ratio, the Board of 
Directors once again, unanimously, recommends the merger to the shareholders, 
and urges shareholder approval and the adoption of the Merger Agreement, as 
amended.
    

Merger Recommendation and Reasons for Transaction

The terms of the Merger and the Merger Agreement, including the Exchange Ratio, 
were the result of arms length negotiations between MID STATES and BANC ONE and 
their respective representatives.  In the course of reaching its decision to 
approve the Merger Agreement, the Board of Directors of MID STATES consulted 
with its legal and financial advisors as well as with management of MID STATES, 
and, without assigning any relative or specific weights, considered numerous 
factors, including but not limited to the following:

(1) That a business combination with a larger bank holding company, such as 
    BANC ONE, would provide both greater short-term and long-term value to MID 
    STATES' shareholders than other alternatives available and would enhance 
    MID STATES' competitiveness and its ability to serve its depositors, 
    customers, and the communities in which it operates;

(2) BANC ONE's record of fair treatment of employees of acquired institutions 
    and outstanding record of community services and support;

(3) BANC ONE's significant long-term experience in integrating the operations 
    of banks and bank holding companies;

(4) The economic conditions and prospects for the market in which MID STATES 
    operates, and competitive pressures in the financial services industry in 
    general and the banking industry in particular;

(5) That the Merger offered MID STATES' shareholders the prospect for 
       substantially     higher dividends, a higher current trading value 
    for their shares, and better prospects for future growth than if MID 
    STATES were to remain independent;

(6) The bank regulatory environment in general;

(7) The business, results of operations, asset quality and financial condition 
    of BANC ONE, the future growth prospects of BANC ONE and MID STATES 
    following the Merger, and the potential synergies and cost savings expected 
    to be realized from the Merger; and

(8) the presentations of MID STATES' financial advisor   s    , DLJ    and 
    TCC,     and the opinions rendered by DLJ    and TCC     to the effect 
    that the Exchange    Ratio     was fair, from a financial point of view, 
    to the holders of MID STATES Common Stock.  See "Merger-Opinion   s     of 
    Investment Banker   s    ."


MID STATES' Board of Directors believes that the affiliation with BANC ONE will 
result in a competitively stronger combined entity with increased financial and 
human resources which will lead to enhanced financial performance and a larger 
and more geographically diverse banking operation.

As of               , 1994, the directors and executive officers of MID STATES, 
together with their affiliates and associates, as a group, were entitled to 
vote approximately    160,000     shares of MID STATES Common Stock 
representing approximately    51%     of the shares outstanding.  These persons 
will be entitled to receive the same consideration for their shares as any 
other MID STATES shareholder upon approval of the Merger.  MID STATES believes 
that all of the directors' and executive officers' shares will be voted 
in favor of the Merger.  After the Merger, MID STATES' directors and executive 
officers will own less than 1% of the shares of BANC ONE Common Stock 
outstanding.

MID STATES' BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE MERGER AGREEMENT 
BE APPROVED BY THE SHAREHOLDERS OF MID STATES.

BANC ONE believes that the affiliation of MID STATES with BANC ONE and the 
acquisition of First National thereby will provide BANC ONE with a presence in 
the Moline, Illinois area and an expansion of BANC ONE's customer base and 
assets.  Such expansion will provide BANC ONE with the opportunity to realize 
increased economies of scale while serving new customers with the expertise and 
assistance of the capable and experienced staff of First National.

Opinion   s     of Investment Banker   s    

   
Opinion of Donaldson, Lufkin & Jenrette Securities Corporation

The MID STATES Board retained DLJ, among other things, to advise it as to the 
fairness of the consideration to be received by the shareholders of MID STATES 
pursuant to the terms of the Merger Agreement.

DLJ is a nationally recognized investment banking firm regularly engaged in the 
valuation of financial institutions and their securities in connection with 
mergers and acquisitions.  The MID STATES Board selected DLJ on the basis of, 
among other things, its perceived expertise in merger and acquisition 
transactions and its familiarity with the most likely potential merger partners 
for MID STATES and the regional banking industry.

DLJ has rendered a written opinion to the MID STATES Board to the effect that 
the Exchange Ratio is fair, from a financial point of view, to the holders of 
MID STATES Common Stock.  DLJ's opinion is attached hereto as Exhibit A.  MID 
STATES' shareholders are encouraged to read the DLJ opinion in its entirety.

DLJ's opinion is directed to the Board of Directors of MID STATES only and is 
directed only to the Exchange Ratio and does not constitute a recommendation to 
any MID STATES shareholder as to how such shareholder should vote at the MID 
STATES Special Meeting of Shareholders.

For purposes of its opinion and in connection with its review of the proposed 
transaction, DLJ, among other things: (a) reviewed the Merger Agreement, as 
amended, and the Prospectus and Proxy Statement; (b) reviewed certain publicly 
available financial statements both audited and unaudited, for MID STATES and 
BANC ONE; (c) reviewed certain financial statements and other financial and 
operating data concerning MID STATES and BANC ONE prepared by their respective 
managements; (d) reviewed certain financial projections of MID STATES and BANC 
ONE, both on a stand-alone and on a combined basis, prepared by their 
respective managements; (e) discussed certain aspects of the past and current 
business operations, results of regulatory examinations and actions, financial 
condition and future prospects of MID STATES and BANC ONE with certain members 
of the management of MID STATES and BANC ONE; (f) reviewed reported market 
prices and historical trading activity of MID STATES Common Stock and BANC ONE 
Common Stock; (g) reviewed certain aspects of the financial performance of MID 
STATES and BANC ONE Common Stock and compared such financial performance of MID 
STATE and BANC ONE, together with the stock market data relating to MID STATES 
and BANC ONE, with similar data available for certain other financial 
institutions and certain of their publicly traded securities; (h) reviewed the 
financial terms, to the extent publicly available, of certain recent business 
combinations involving other financial institutions; (i) participated in 
discussions and negotiations among representatives of MID STATES and BANC ONE 
and their financial and legal advisors; and (j) conducted such other studies, 
analyses and examinations as DLJ deemed appropriate.

DLJ relied upon and assumed without independent verification the accuracy and 
completeness of all of the financial and other information provided to it by 
MID STATES, BANC ONE and their respective representatives and the publicly 
available information reviewed by DLJ. DLJ also relied upon the managements of 
both MID STATES and BANC ONE as to the reasonableness and achievability of the 
financial and operating forecasts provided to DLJ (and the assumptions and 
basis therefor).  In that regard, DLJ assumed that such forecasts reflect the 
best available estimates and judgments of such respective managements and that 
such projections and forecasts will be realized in the amounts and in the time 
period currently estimated by the managements of both MID STATES and BANC ONE.  
DLJ did not independently verify and relied on and assumed that the aggregate 
allowances for loan losses set forth in the balance sheets of each MID STATES 
and BANC ONE at December 31, 1993 are adequate to cover such losses and 
complied fully with applicable law, regulatory policy and sound banking 
practice as of the date of such financial statements.  DLJ was not retained to 
and did not conduct a physical inspection of any of the properties or 
facilities of MID STATES or BANC ONE, nor did DLJ make any independent 
evaluation or appraisal of the assets, liabilities or prospects of MID STATES 
or BANC ONE, was not furnished with any such evaluation or appraisal and did 
not review any individual credit files.  DLJ also assumed that the Merger is, 
and will be, in compliance with all laws and regulations that are applicable to 
MID STATES and BANC ONE. DLJ was informed by MID STATES and assumed for 
purposes of its opinion that the Merger will be recorded as a pooling of 
interests under generally accepted accounting principles.

Prior to rendering its opinion dated              , 1994 to the MID STATES 
Board, DLJ rendered an oral opinion to the Board of March 28, 1994.  See 
"MERGER/Background of Transaction" for discussion of the events preceding DLJ's 
rendering of its oral opinion.  Set forth below is a brief summary of the 
analyses performed by DLJ in reaching its March 28, 1994 oral opinion.

Stock Trading History.  DLJ examined the history of trading prices and volume 
for MID STATES Common Stock (to the extent known by MID STATES management and 
conveyed to DLJ) and BANC ONE Common Stock and the relationship between the 
movements of such common stock prices to prices in the Standard & Poor's 
Regional Bank Index, the BANC ONE Peer Group (as defined below) and the MID 
STATES Peer Group (as defined below).

Discounted Cash Flow Analysis.  Using discounted cash flow analysis, DLJ 
estimated the future dividend streams that MID STATES could produce over the 
five years ending December 31, 1998, assuming a minimum required tangible 
equity level of 6% of tangible total assets, if MID STATES performed in 
accordance with management's forecast.  DLJ also estimated the terminal value 
of MID STATES' common equity as of December 31, 1998, by applying a range of 
multiples to MID STATES' projected 1998 earnings.  The dividend streams and 
terminal value were discounted to present values using discount rates ranging 
from 11% to 15%, which reflect different assumptions regarding the required 
rates of return of holders and prospective buyers of MID STATES Common Stock.  
The range of present values per share of MID STATES Common Stock resulting from 
this analysis was $78.75 to $98.20.

Comparison with Selected Companies.  DLJ compared selected financial ratios for 
MID STATES to the corresponding ratios of ANB Corporation; Independent Bank 
Corporation; Northwest Illinois Bancorp, Inc.; Princeton National Bancorp; and 
Premier Financial Services, Inc. (the "MID STATES Peer Group"), and for BANC 
ONE to the corresponding ratios of Boatmen's Bancshares, Inc.; Comerica 
Incorporated; First Bank System, Inc.; First of America Bank Corporation; 
Firstar Corporation; NBD Bancorp, Inc.; Norwest Corporation; Fifth Third 
Bancorp; Huntington Bancshares Incorporated; National City Corporation; Old 
Kent Financial Corporation; and Society Corporation (the "BANC ONE Peer 
Group").  Such ratios included the regulatory "leverage ratio," return on 
average total assets, return on average common equity, loan loss reserve to 
non-performing loans (defined as non-accrual loans, loans 90 days of more past 
due but still accruing interest and restructured loans) and non-performing 
assets (defined as non-performing loans plus other real estate owned) to total 
loans plus other real estate owned, market price to latest twelve months' 
("LTM") earnings per share ("EPS") and market price to book value per share.  
All ratios were based on financial data at or for the twelve months ended 
December 31, 1993.  Market prices as of March 22, 1994 were used for all 
companies except MID STATES, for which the last sales price known to MID STATES 
management prior to announcement of the Merger Agreement was used.

DLJ compared the mean values for each of such ratios for the MID STATES Peer 
Group with the corresponding ratio for MID STATES.  This analysis showed that 
the MID STATES Peer Group had a mean leverage ratio of 8.9% as compared with 
10.5% for MID STATES; a mean return on average assets of 1.18%, as compared 
with 1.08% for MID STATES; a mean return on average common equity of 12.0%, as 
compared with 10.5% for MID STATES; a mean ratio of loan loss reserve to 
non-performing loans of 192%, as compared with 194% for MID STATES; a mean 
ratio of non-performing assets to loans plus other real estate owned of 1.15%, 
as compared with 0.65% for MID STATES; a mean ratio of market price to LTM EPS 
of 10.9 times, as compared with 6.6 times for MID STATES; and a mean ratio of 
market price to book value per share of 1.24 times, as compared with 0.67 times 
for MID STATES.

DLJ also compared the mean values for each of such ratios for the BANC ONE Peer 
Group with the corresponding ratio for BANC ONE.  This analysis showed that the 
BANC ONE Peer Group had a mean leverage ratio of 7.66% as compared with 8.67% 
for BANC ONE; a mean return on average assets of 1.37%, as compared with 1.50% 
for BANC ONE; a mean return on average common equity of 16.8%, as compared with 
17.1% for BANC ONE; a mean ratio of loan loss reserve to non-performing loans 
of 305%, as compared with 224% for BANC ONE; a mean ratio of non-performing 
assets to loans plus other real estate owned of 1.09%, as compared with 1.12% 
for BANC ONE; a mean ratio of market price to LTM EPS of 11.1 times, as 
compared with 11.4 times for BANC ONE; and a mean ratio of market price to book 
value per share of 1.78 times, as compared with 1.87 times for BANC ONE.

Analysis of Selected Merger Transactions.  DLJ reviewed selected mergers 
announced from January 1, 1992 through March 22, 1994 involving acquisitions of 
banks or bank holding companies headquartered in Illinois or states contiguous 
to Illinois with assets between $100 million and $300 million.  Specifically, 
DLJ reviewed the mergers involving the following pairs of institutions:  AMCORE 
Financial/First State Bancorp; Norwest Corporation/La Porte Bancorp; Old 
National Bancorp/Indiana State Bank of Terre Haute; Chemical Financial 
Corporation/Key State Bank; Citizens Banking Corporation/Royal Bank Group; 
Mercantile Bancorporation/Mount Vernon Bancorp; National City 
Bancshares/Lincolnland Bancorp; National City Bancshares/Sure Financial 
Corporation; F&M Bancorporation/First National Financial Corporation; Norwest 
Corporation/Financial Concepts Bancorp; Old National Bancorp/DCB Corporation; 
CNB Bancshares, Inc./South Central Illinois Bancorp; Firstbank of Illinois 
Corporation/First Highland Corporation; Society Corporation/First of America 
Bank - Monroe; and Old National Bancorp/Palmer Bancorp, Inc.  DLJ calculated 
the multiples of the offer value over the LTM EPS and book value per share of 
the acquired company in each transaction.  The analysis yielded a range of 
multiples of LTM EPS of 7.7 times to 38.6 times, with a mean of 16.9 times and 
a median of 15.4 times; and a range of multiples of book value of 1.00 times to 
2.23 times, with a mean of 1.66 times and a median of 1.69 times.

DLJ compared these multiples with the corresponding multiples for the Merger, 
valuing the Exchange Ratio based on Banc One's closing price as of March 25, 
1994.  In calculating the multiples for the Merger, DLJ used the last sale 
price of MID STATES Common Stock known to MID STATES management prior to 
announcement of the Merger Agreement, EPS for the year ended December 31, 1993, 
and book value per share as of December 31, 1993.  This analysis indicated that 
the value of the Exchange Ratio represented multiples of MID STATES' market 
price per share, EPS and book value per share of 2.21 times, 14.5 times and 
1.47 times, respectively.

No company or transaction used in the above analyses as a comparison is 
identical to MID STATES, BANC ONE or the Merger.  Accordingly, an analysis of 
the results of the foregoing is not mathematical; rather, it involves complex 
considerations and judgments concerning differences in financial and operating 
characteristics of the companies and other facts that could affect the public 
trading value of the companies to which they are being compared.

In connection with its written opinion dated as of              , 1994, DLJ 
performed procedures to update certain of its analyses and reviewed the 
assumptions on which such analyses were based and the factors considered in 
connection therewith.

Although the summary set forth above does not purport to be a complete 
description of the analyses performed by DLJ, the material analyses performed 
by DLJ in rendering its opinion have been summarized above.  However, the 
preparation of a fairness opinion is not necessarily susceptible to partial 
analysis or summary description.  DLJ believes that its analyses and the 
summary set forth above must be considered as a whole and that selecting 
portions of its analyses, without considering all factors and analyses, would 
create an incomplete view of the process underlying the analyses by which DLJ 
reached its opinions.  In addition, DLJ may have given various analyses more or 
less weight than other analyses, but no analysis was given materially more 
weight than any other analysis.  Also, DLJ may have deemed various assumptions 
more or less probable that other assumptions, so that the ranges of valuations 
resulting from any particular analysis described above should not be taken to 
be DLJ's view of the actual value of MID STATES or the combined company.

In performing its analyses, DLJ made numerous assumptions with respect to 
industry performance, general business and economic conditions and other 
matters, many of which are beyond the control of MID STATES and BANC ONE.  The 
analyses performed by DLJ are not necessarily indicative of actual value or 
actual future results, which may be significantly more or less favorable than 
suggested by such analyses.  Such analyses were prepared solely as part of 
DLJ's analysis of the fairness, from a financial point of view, of the Exchange 
Ratio.  The analyses do not purport to be appraisals or to reflect the prices 
at which a company might actually be sold or the prices at which any securities 
may trade at the present time or at any time in the future.  In addition, as 
described above, DLJ's opinion to the MID STATES Board was one of many factors 
taken into consideration by the MID STATES Board in making its determination to 
approve the Merger Agreement.

Pursuant to the terms of a letter agreement dated November 6, 1992 (the 
"Engagement Letter"), for DLJ's services in connection with the 
Merger,including the rendering of its original fairness opinion, MID STATES 
(i) has paid DLJ $175,000, and (ii) has agreed to pay DLJ an amount equal to 
1.0% of the first $34 million aggregate amount of consideration received by MID 
STATES' shareholders (treating any options, warrants or other rights of 
conversion as outstanding), plus 5.0% of the aggregate amount received by MID 
STATES' shareholders in excess of $34 million and an additional 5.0% of the 
aggregate amount received in excess of $37 million, less the amount paid by MID 
STATES pursuant to clause (i) above.  Mid States has also agreed to pay DLJ 
$150,000 for its second fairness opinion (Exhibit A hereto); such amount is not 
offset against the fee described in clause (ii) above. Because the major 
portion of the aggregate consideration to be received by MID STATES' 
shareholders is to be paid in the form of securities, the Engagement Letter 
provides that the value of such securities, for purposes of calculating the fee 
payable to DLJ, will be determined by the last sale price for such securities 
on the last trading day thereof prior to consummation of the Merger.  Such fee 
shall be payable in cash upon consummation of the Merger.  MID STATES has also 
agreed to reimburse DLJ for all reasonable out-of-pocket expenses, including 
reasonable fees and disbursements of legal counsel, and has agreed to indemnify 
DLJ against certain liabilities.  The DLJ fee is an obligation of MID STATES, 
which is payable upon the consummation of the Merger, and will have no impact 
on the consideration to be received by each MID STATES shareholder.

DLJ may, in the ordinary course of its business, trade securities of MID STATES 
and BANC ONE for its own account or for the accounts of customers and thus may 
hold long or short positions in such securities at any time.

Opinion of The Chicago Corporation

The Chicago Corporation ("TCC") has delivered its written opinion to MID STATES 
Board of Directors that, based upon and subject to the various considerations 
set forth in the opinion dated                      , 1994, the Exchange Ratio 
being received by MID STATES shareholders in the merger is fair from a 
financial point of view to MID STATES' shareholders as of the date of its 
opinion.  The Board of Directors has carefully and thoroughly reviewed the 
materials and presentations of TCC and has made inquiries of TCC personnel as 
to the methodology and the assumptions utilized in its analysis.  No 
limitations were imposed by MID STATES' Board of Directors upon TCC with 
respect to the investigations made or procedures followed by it in rendering 
its opinion.

The full text of TCC's opinion, which sets forth assumptions made, matters 
considered and limitations on the review undertaken, is attached hereto as 
Exhibit B.  MID STATES shareholders are urged to read the opinion in its 
entirety.

TCC's opinion is directed only to the Exchange Ratio to be received in the 
merger and does not constitute a recommendation to any MID STATES shareholder 
as to how such shareholder should vote at the Special Meeting.  The summary of 
TCC's opinion set forth in this Prospectus and Proxy Statement is qualified in 
its entirety by reference to the full text of such opinion attached hereto as 
Exhibit B.

MID STATES retained TCC as a financial advisor on the basis of the firm's 
reputation, experience and familiarity with the banking industry and with 
merger and acquisition transactions.  As part of its investment banking 
business, TCC is regularly engaged in the valuation of businesses in connection 
with mergers and acquisitions, negotiated underwritings, secondary distribution 
of listed and unlisted securities, private placements and valuations for 
corporate and other purposes.

During the course of its engagement, and as a basis for arriving at its 
opinion, TCC reviewed and analyzed material bearing upon the financial and 
operating condition of MID STATES and BANC ONE and material prepared in 
connection with the merger, as follows: (i) the Merger Agreement, as amended; 
(ii) publicly available information concerning MID STATES and BANC ONE 
including among other things annual reports on form 10-KSB and 10-K, 
respectively, for each of the last five fiscal years ended; (iii) the nature 
and terms of recent sale and merger transactions involving financial 
institutions that TCC considered reasonably similar to MID STATES and BANC ONE 
in size, financial character, operating character, historical performance and 
geographic market; (iv) historical and current market data for MID STATES 
Common Stock and BANC ONE Common Stock and financial and other information 
provided to TCC by management of MID STATES and BANC ONE, and (v) the 
Registration Statement and this Prospectus and Proxy Statement.  These analyses 
are discussed in more detail below.  In addition, TCC conducted meetings with 
members of senior management of MID STATES and BANC ONE for the purpose of 
reviewing the future prospects of MID STATES and BANC ONE.  TCC evaluated the 
pro forma ownership of BANC ONE Common Stock by MID STATES shareholders, 
relative to the pro forma contribution of MID STATES' assets, liabilities, 
equity and earnings of the proposed combined company.  TCC also took into 
account its experience in other transactions, as well as its knowledge of the 
banking industry and its general experience in securities valuations.  In 
rendering its opinion, TCC assumed without independent verification, the 
accuracy and completeness of the financial and other information and 
representations provided to it by MID STATES and BANC ONE.

The following is a summary of all material terms considered and the analyses 
performed by TCC in rendering its opinion during the course of its engagement 
in connection with its               , 1994 opinion.

Net Present Value Analysis.  TCC prepared a net present value analysis which 
indicated theoretical values for MID STATES based on return on average assets 
ranging between 1.00% and 1.50% and asset growth rates ranging between 2.00% 
and 10.00%.  The results of this analysis indicated a range of theoretical 
values for MID STATES between $68.05 per share (1.00% return on average assets; 
2.00% asset growth rate) and $138.52 per share (1.50% return on average assets; 
10.00% asset growth rate).  At a return on average assets ratio of 1.10%, which 
approximated MID STATES historical performance, theoretical values ranged from 
$74.85 per share (2.00% asset growth rate) to $101.58 per share (10.00% asset 
growth rate).  At an asset growth rate of 4.00%, which approximated MID STATES' 
historical performance, theoretical values ranged from $73.55 per share (1.00% 
return on average assets) to $110.32  per share (1.50% return on average 
assets).

Contribution Analysis.  TCC prepared a contribution analysis showing the 
percentages of assets, deposits, common equity, and 1992 and 1993 net income 
and estimated 1994 and 1995 net income contributed to the combined company on a 
pro forma basis by MID STATES and BANC ONE, and compared these percentages to 
the pro forma ownership of BANC ONE.  This analysis showed that MID STATES, as 
of December 31, 1993, would contribute 0.24% of pro forma consolidated total 
assets, 0.27% of deposits, 0.29% of common equity, 0.23% of 1992 and 0.18% of 
1993 net income and 0.19% of estimated 1994 and 0.18% estimated 1995 net 
income.  Based on the BANC ONE offer, shareholders of MID STATES would own 
approximately 0.24% of the pro forma common shares outstanding of BANC ONE.

Comparable Transaction Analysis.  TCC reviewed selected comparable merger and 
acquisition transactions.  The following merger transactions were reviewed 
based on publicly available data (the acquiror is named first and underlined, 
followed by the seller):

    AMCORE Financial, Inc., First State Bancorp of Princeton; First Banks, 
    Inc., First FSB of Proviso Township; Mercantile Bancorporation, Inc., Mount 
    Vernon Bancorp; CNB Bancshares, Inc., South Central Illinois Bancorp; Old 
    Kent Financial Corporation, University Financial Corporation; Old National 
    Bancorp, Palmer Bancorp, Inc.; BANC ONE Corporation, Jefferson Bancorp, 
    Inc.; AMCORE Financial, Inc., Dixon Bancorp, Inc.; Mercantile 
    Bancorporation, Inc., Old National Bancshares; Old National Bancorp, SBT 
    Bancorp, Inc.; and AMCORE Financial, Inc., Central of Illinois, Inc.  
    Transactions were selected on the basis of comparability of absolute 
    transaction value and the perceived comparability of the markets served by 
    the acquired institutions to those of MID STATES.  For the comparable 
    transactions, the multiple of price to trailing 12 months earnings ranged 
    from 8.2 to 22.5 with an average of 13.0.  At March 25, 1994, the BANC ONE 
    proposed purchase price represented a multiple of price to trailing 12 
    months earnings of 14.5.  For the comparable transactions, the multiple of 
    purchase price to book value range from 0.95 to 1.95 with an average of 
    1.43.  The BANC ONE offer to MID STATES represented a multiple of price to 
    December 31, 1993 book value of 1.47.

Financial Implications to MID STATES Shareholders.  TCC prepared an analysis of 
the financial implications of the BANC ONE offer to a MID STATES shareholder.  
This analysis indicated that on a pro forma equivalent basis a shareholder of 
MID STATES would achieve an increase in earnings per share, a decrease in per 
share dividends and an increase in book value per share as a result of the 
consummation of the merger, assuming a dividend payout ratio significantly 
higher than MID STATES' historical payout ratio.

Another analysis of the financial implications of the BANC ONE offer kept MID 
STATES' dividend payout ratio in line with historical dividend payouts.  This 
analysis indicated that on a pro forma equivalent basis a shareholder of MID 
STATES would achieve an increase in earnings per share, an increase in 
dividends per share and a decrease in book value per share.

Comparative Shareholder Returns.  TCC presented an analysis of comparative 
theoretical shareholder returns for several scenarios, including MID STATES 
remaining independent, MID STATES being acquired in 1994 and MID STATES being 
acquired in 1997.  This analysis, which was based on the net present value of 
projected dividend streams and projected 1997 common stock valuations (using 
current price-to-trailing twelve month earnings multiples), indicated total 
shareholders returns of 11.4% for MID STATES remaining independent, 31.7% for 
the merger in 1997 and 38.2% based on the acceptance of an offer in 1994.  TCC 
also prepared an analysis of the possible pricing of a merger transaction with 
certain other Midwest-based bank holding companies using estimated 1994 net 
income for MID STATES and stock prices for selected companies and assuming no 
earnings-per-share dilution for the buyer.  The holding companies reviewed 
included:  AMCORE Financial, Inc.; BANC ONE; Commerce Bancshares, Inc.; First 
Bank System, Inc.; First Midwest Bancorp; First of America Bank Corp.; 
Firstbank of Illinois Co.; Firstar Corporation; Hawkeye Bancorporation; Magna 
Group, Inc.; Mercantile Bancorporation, Inc.; Northwest Illinois Bancorp; and 
Norwest Corporation.

Given the assumptions, the analysis indicated that these companies could pay a 
high of $107.28 per share, a low of $66.12 per share and an average price of 
$81.72 per share for all of the shares of MID STATES.

A second analysis was conducted under the aforementioned methodology with the 
1994 net income of MID STATES to include a tax-effected 15% reduction in 
operating expenses.  Under that assumption the previously listed companies 
could pay a high of $131.87 per share, a low of $81.27 per share and an average 
price of $100.45 per share for all the shares of MID STATES.

Comparable Company Analysis.  TCC compared the market price, market-to-book 
value and price-to-earnings multiples of BANC ONE Common Stock with the 
individual market multiples and averages of the following selected comparable 
companies which it deemed to be reasonably similar to BANC ONE in size, 
financial character, operating character, historical performance and geographic 
market:  BANC ONE; BankAmerica Corporation; Boatmen's Bancshares, Inc.; 
Citicorp; Comerica Incorporated; First Bank System, Inc.; First Chicago 
Corporation; First Interstate Bancorp; First of America Bank Corp.; First Union 
Corporation; Fleet Financial Group; KeyCorp; Mellon Bank Corporation; NBD 
Bancorp, Inc.; National City Corporation; NationsBank Corporation; Norwest 
Corporation; and PNC Bank Corp.  This analysis indicated that BANC ONE Common 
Stock sold at a price of 1.87 times the December 31, 1993 book value and the 
comparables sold at an average price of 1.56 times book value.  BANC ONE's 
Common Stock sold at a multiple of price to trailing 12 months earnings of 
11.2, while the comparable group average price-to-earnings multiple was 10.0.

The summary of TCC's analysis set forth above is a fair summary thereof but 
does not purport to be a complete description of the presentations by TCC to 
the MID STATES Board of Directors.  TCC believes that its analysis and the 
summary set forth above must be considered as a whole and that selecting 
portions of analysis, without considering all factors and analyses, could 
create an incomplete view of the process by which a fairness opinion is 
rendered.  In connection with its analyses, TCC assumed that there would be no 
material adverse change in general economic, business, market financial and 
regulatory conditions, all of which are beyond the control of BANC ONE and MID 
STATES.  The analyses performed by TCC are not necessarily indicative of actual 
values of future results, which may be significantly more or less favorable 
than suggested by such analyses.

Fees and Indemnification.  The fees due to TCC under the Agreement between TCC 
and MID STATES (the "TCC Agreement") were payable by MID STATES as follows: 
$25,000 at the date of execution of TCC Agreement and $25,000 upon delivery of 
a verbal opinion conclusions and $50,000 at the time a written opinion is 
delivered for the use with this Prospectus and Proxy Statement.  The TCC fee 
will have no impact on the consideration to be received by each MID STATES' 
shareholder.

In addition to such fees, MID STATES has agreed to reimburse TCC for all 
reasonable out-of-pocket expenses and will pay to TCC a fee of $1,500 per day 
for preparation and court appearances with regard to the fairness opinion.  MID 
STATES has also agreed to indemnify TCC, its officers, directors, agents, 
employees and certain controlling persons from and against any losses, claims, 
damages and liabilities in connection with or arising out of the transactions 
or services referred to in TCC Agreement.  This indemnification is subject to 
certain conditions and procedures set forth in an indemnification agreement 
between MID STATES and TCC.
    

Interest of Certain Persons in the Merger

After consummation of the Merger, MID STATES will be merged into Banc One 
Illinois and the separate corporate existence of MID STATES will cease.  It is 
anticipated that Mr. Thomas H. Robinson, President, CEO and a director of MID 
STATES and First National, will join the Board of Directors of Banc One 
Illinois.  Following the Merger, First National will operate under the name 
Bank One, Quad Cities, N.A. and the present directors, officers and employees 
of First National will continue in the same capacities and one or more officers 
of Banc One Illinois may be added to the Board.

MID STATES and First National entered into an employment agreement with 
Mr. Robinson on June 15, 1992 for the purpose of memorializing the continuation 
of the then effective employment terms and practices and to provide 
Mr. Robinson with a three-year employment guarantee in the event of a change in 
control of MID STATES.  The employment agreement was amended and restated as of 
May 17, 1993 to clarify the terms of the agreement and certain procedural 
matters thereunder and for the joint obligation of both MID STATES and First 
National for the compensation and benefits thereunder.  Specifically, the 
agreement provides that Mr. Robinson's employment will be continued for a 
period of three years following a change in control on the terms at least as 
favorable as those in effect immediately prior to the change in control.  If 
Banc One Illinois or First National terminates Mr. Robinson's employment during 
such three-year period, or if Mr. Robinson should resign during such period for 
"good reason" (defined to mean a significant change in Mr. Robinson's authority 
or duties, a reduction in the compensation or benefits required under the 
agreement, or a reasonable determination by him that he is unable to exercise 
such authorities or responsibilities as a result of the change in control), 
then Banc One Illinois and First National will be obligated to continue to pay 
Mr. Robinson his current base salary and the value of the incentive and 
retirement compensation to which he would have been entitled during the 
remainder of the three-year term and to continue to provide all medical, life 
and other insurance protections for such period.  In the event that the payment 
of such salary and benefits results in the imposition upon Mr. Robinson of the 
excise tax applicable to certain excess parachute payments under the Code, the 
agreement provides that Mr. Robinson will be entitled to a supplemental payment 
equal to such excise tax, and all taxes imposed on such supplemental payment.  
The Merger will constitute a change in control for purposes of the agreement 
and Banc One Illinois has agreed to assume the obligations of MID STATES under 
the agreement following the Merger.  Mr. Robinson's annual base salary as of 
October 1, 1993 is $125,000.

Although it is the intent of MID STATES and BANC ONE to continue to provide 
employment opportunities for employees of MID STATES and First National 
following the Merger, the Board of Directors of MID STATES, with BANC ONE's 
consent, has adopted a Separation Assistance Plan to provide separation pay to 
employees of MID STATES or First National in the event that a reduction in the 
work force of MID STATES or First National occurs within one year after the 
Merger.  Under the Separation Assistance Plan, Banc One Illinois and First 
National will first attempt to provide employment alternatives for within the 
BANC ONE system for employees affected by the discontinuation of job positions 
or functions.  If such alternatives are not possible, then the employee whose 
job position or function was discontinued shall be entitled to separation pay 
equal to one week's pay for each full year of service with MID STATES or First 
National, subject to a maximum of 26 weeks.  Any employee who is a vice 
president shall be entitled to 26 weeks of separation pay, regardless of the 
employee's years of service.  Mr. Robinson is not eligible to receive a benefit 
under the Separation Assistance Plan.

Effect on Employee Benefits

Pursuant to the Merger Agreement, BANC ONE covenants to comply with its 
agreements with respect to certain employee benefits sat forth in a letter 
agreement dated May 24, 1993 between BANC ONE and MID STATES (the "Benefits 
Agreement").

The Benefits Agreement provides that, upon the Merger or on such subsequent 
date as BANC ONE shall determine, BANC ONE will cause coverage under the 
various employee benefit plans and programs maintained by BANC ONE to be 
extended to the employees of MID STATES and First National.  As a result, such 
employees will participate in, among other plans, the BANC ONE Retirement Plan, 
Supplemental Employees Retirement Plan, Profit Sharing and 401(k) Plan, 
Employee Stock Purchase Plan, and medical and life insurance programs.  The 
service of such employees with MID STATES and First National will be recognized 
under the BANC ONE plans for purposes of determining eligibility for 
participation and vesting of benefits under the BANC ONE plans; service for 
purposes of measuring benefits earned under the BANC ONE plans will be measured 
from the date of the Merger.  The employee benefit plans maintained by MID 
STATES and First National will be terminated or merged into the BANC ONE plans 
when the BANC ONE plans are extended to the MID STATES and First National 
employees, subject to the inclusion under the BANC ONE plans of certain 
benefits accrued during the calendar year in which the transition to the BANC 
ONE plans occur.

     otherwise permitted by the Merger Agreement, it will not

     (a)  from March 31, 1993 to the Effective Time, pay any cash dividends;

     "MERGER-Fractional Shares") and shares of BANC ONE Common Stock to which 
     holders of MID STATES Common Stock would have been entitled as of the 
     consummation of the Merger, but who have taken steps to perfect their 
     rights as dissenting shareholders pursuant to applicable law, shall not 
     exceed 10% of the maximum aggregate number of shares of BANC ONE Common 
     Stock which could be issued as a result of the Merger;

 (9) the shares of BANC ONE Common Stock to be issued in exchange for MID 
     STATES Common Stock shall have been listed on the NYSE;

(10) receipt by BANC ONE of the written opinion of Coopers & Lybrand,

(11) the holders of all credit agreements on which MID STATES or any SUBSIDIARY 
     is the maker, issuer or guarantor and which contain provisions which make 
     the acquisition of MID STATES by or merger into another entity a condition 
     of default or acceleration, shall have provided BANC ONE with a written 
     waiver of all such provisions;

(12) the total number of shares of MID STATES Common Stock issued and 
     outstanding shall not be more than 311,560 shares; and

(13) receipt by MID STATES of    opinions     from    each of     DLJ    and

     financial point of view to the holders of MID STATES Common Stock and such 
     opinions shall not have been withdrawn prior to the Effective Time.


The provisions of the Merger Agreement, including the foregoing conditions, may 
be waived at any time by the party which is entitled to the benefits thereof.  
However, after the shareholders of MID STATES have approved the Merger 
Agreement, MID STATES may only amend the Merger Agreement if, in the opinion of 
MID STATES' Board of Directors, such amendment will not have a material adverse 
effect on the benefits intended under the Merger Agreement for the shareholders 
of MID STATES.

The Merger Agreement may be terminated at any time prior to the Effective Time 
of the Merger, whether before or after approval by the shareholders of MID 
STATES, by written notice from BANC ONE to MID STATES, or from MID STATES to 
BANC ONE, as the case may be, upon the occurrence of any of the following:  (i) 
if any material condition to either party's obligations under the Merger 
Agreement is not satisfied or waived at the time or times contemplated thereby 
(each party's right to terminate under this clause (i) shall relate only to 
conditions to that party's obligations); (ii) in the event of a material breach 
by a party of any representation, warranty, condition or agreement contained in 
the Merger Agreement that is not cured within 30 days of the giving of notice 
to such party by the other party; or (iii) if the Merger shall not have been 
consummated on or before July 1, 1994.  The Merger Agreement also may be 
terminated, and the Merger thereby abandoned, by the mutual consent of the 
Boards of Directors of MID STATES and BANC ONE at any time prior to the 
effective date of the Merger.

MID STATES, by action of its Board of Directors, may elect to terminate the 
Merger Agreement, whether before or after approval of the Merger by the 
shareholders of MID STATES, by giving three (3) days written notice of such 
election to BANC ONE.

If the Merger is not consummated other than by reason of a willful breach of 
any party to the Merger Agreement, MID STATES, BANC ONE and Banc One Illinois 
will each pay all of its own expenses incurred incident to such transaction, 
except for printing expenses which will be paid by BANC ONE.    BANC ONE has 
also agreed to reimburse MID STATES for one-half of all legal and accounting 
fees and the expenses and fees of DLJ and TCC incurred in connection with the 
Merger after January 25, 1994.    

Federal Income Tax Consequences

The following is a summary of certain material U.S. federal income tax 
consequences of the Merger, including certain consequences to holders of MID 
STATES Common Stock who are citizens or residents of the United States and who 
hold their shares as capital assets.  It does not discuss all tax consequences 
that may be relevant to MID STATES shareholders subject to special federal 
income tax treatment (such as insurance companies, dealers in securities, 
certain retirement plans, financial institutions, tax exempt organizations or 
foreign persons) or to MID STATES shareholders who acquired their shares of MID 
STATES Common Stock pursuant to the exercise of employee stock options or 
otherwise as compensation.  The summary does not address the state, local or 
foreign tax consequences of the Merger, if any.

As a condition to the closing, MID STATES and BANC ONE    received     the 
opinion of Vedder, Price, Kaufman & Kammholz, dated    April 20, 1994    
that, for federal income tax purposes:

(1)  The Merger will constitute a reorganization within the meaning of 
     Section 368(a)(1)(A) and Section 368(a)(2)(D) of the Internal Revenue Code 
     of 1986, as amended;

(2)  No gain or loss will be recognized by Banc One Illinois or MID STATES by 
     reason of the Merger;

(3)  No gain or loss will be recognized by the shareholders of MID STATES on 
     the exchange of their shares of MID STATES Common Stock for shares of BANC 
     ONE Common Stock, except as described below with respect to cash received 
     pursuant to the exercise of statutory dissenters' rights or in lieu of 
     fractional share interests;

(4)  The tax basis of the BANC ONE Common Stock (including fractional share 
     interests) received by holders of MID STATES Common Stock will be the same 
     as the tax basis of the MID STATES Common Stock surrendered in exchange 
     therefor; and

(5)  The holding period of the BANC ONE Common Stock received by a holder of 
     MID STATES Common Stock will include the period for which the MID STATES 
     Common Stock exchanged therefor was held, provided the exchanged MID 
     STATES Common Stock was held as a capital asset by such holder on the date 
     of the exchange.


A MID STATES shareholder who receives cash in lieu of a fractional share 
interest in BANC ONE Common Stock will be treated as having received the cash 
in redemption of the fractional share interest.  The receipt of cash in lieu of 
a fractional share interest should generally result in capital gain or loss to 
the holder in an amount equal to the difference between the amount of cash 
received and the portion of the holder's tax basis in the MID STATES Common 
Stock allocable to the fractional share interest.  Such capital gain or loss 
will be long-term capital gain or loss if the holder's holding period for the 
BANC ONE Common Stock received, determined as set forth above, is longer than 
one year.

A dissenting shareholder who receives cash in exchange for shares of MID STATES 
Common Stock will generally recognize capital gain or loss equal to the 
difference between the amount of cash received and the holder's tax basis in 
the shares exchanged.  Such capital gain or loss will be long-term capital gain 
or loss if the holder has held the shares for more than one year as of the 
Effective Time of the Merger.

No rulings from the Internal Revenue Service have been or will be sought by 
BANC ONE or MID STATES with respect to the federal income tax consequences of 
the Merger.  The opinion of counsel to be obtained by BANC ONE and MID STATES 
will not be binding upon the Internal Revenue Service, nor will it preclude the 
Service from taking positions contrary to it.  No rulings or opinions with 
respect to state or local tax consequences have been or will be sought by BANC 
ONE or MID STATES.

THE INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION 
ONLY AND IS BASED ON THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (AND 
AUTHORITIES THEREUNDER) AS IN EFFECT ON THE DATE OF THIS PROSPECTUS AND PROXY 
STATEMENT, WITHOUT CONSIDERATION OF THE PARTICULAR FACTS OR CIRCUMSTANCES OF 
ANY SHAREHOLDER.  SHAREHOLDERS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS 
WITH RESPECT TO THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER IN THEIR 
PARTICULAR SITUATIONS, AS WELL AS THE CONSEQUENCES UNDER ANY APPLICABLE STATE, 
LOCAL OR FOREIGN TAX LAWS.

Conversion of Shares and Exchange of Certificates

Upon consummation of the Merger, the outstanding shares of MID STATES Common 
Stock will be converted into shares of BANC ONE Common Stock at the Exchange 
   Ratio     calculated as described under the caption "MERGER--Exchange 
   Ratio    ."  Except in the event that either MID STATES or BANC ONE shall 
declare a stock dividend or distribution upon or subdivide, split up, 
reclassify or combine its respective Common Stock or declare a dividend, or 
make a distribution, on its respective Common Stock in any security convertible 
into such Common Stock prior to the time the Merger becomes effective, no 
further adjustments will be made in the Exchange    Ratio    .  However, in 
the event of such a transaction, appropriate adjustment will be made in the 
Exchange    Ratio    .  The Exchange    Ratio     has been adjusted to 
reflect the effect of all stock splits and dividends.

As soon as practicable after the Merger becomes effective, instructions and 
forms will be furnished to the shareholders of MID STATES for use in exchanging 
their MID STATES share certificates for certificates of BANC ONE Common Stock.  
If any certificate for shares of BANC ONE Common Stock is to be issued in a 
name other than that in which the certificate for shares of MID STATES Common 
Stock surrendered for exchange is registered, the certificate so surrendered 
must be properly endorsed or otherwise be in proper form for transfer and the 
person requesting such exchange must pay to BANC ONE or its transfer agent any 
applicable transfer or other taxes required by reason of the issuance of the 
certificate.

Until so surrendered, certificates formerly representing shares of MID STATES 
Common Stock will be deemed for all purposes to evidence ownership of the 
number of shares of BANC ONE Common Stock into which such shares have been 
converted.  Dividends and other distributions, if any, that become payable on 
BANC ONE Common Stock pending exchange of certificates representing shares of 
MID STATES Common Stock will be retained by BANC ONE until surrender of such 
certificates, at which time such dividends and distributions will be paid, 
without interest.  In addition, after the Effective Time the holders of 
certificates formerly representing shares of MID STATES Common Stock shall 
cease to have rights with respect to such shares (except such rights, if any, 
as holders of certificates representing MID STATES Common Stock may have as 
dissenting shareholders), and, except as aforesaid, their sole rights shall be 
to exchange such certificates for shares of BANC ONE Common Stock in accordance 
with the Merger Agreement.

Fractional Shares

No fractional shares of BANC ONE Common Stock will be exchanged for shares of 
MID STATES Common Stock.  In lieu thereof, each shareholder of MID STATES 
having a fractional interest resulting from the exchange of MID STATES Common 
Stock for BANC ONE Common Stock will be paid by BANC ONE an amount in cash 
equal to the value of such fractional interest based upon the closing price of 
BANC ONE Common Stock on the NYSE on the fifth day immediately preceding the 
day on which the merger is consummated during which shares of BANC ONE Common 
Stock are traded on the NYSE as reported in The Wall Street Journal for NYSE 
Composite Transactions.

Resales by Affiliates

The shares of BANC ONE Common Stock issuable to MID STATES shareholders upon 
consummation of the Merger have been registered under the Securities Act, but 
such registration does not cover resales by affiliates of MID STATES 
("Affiliates").  BANC ONE Common Stock received and beneficially owned by those 
MID STATES shareholders who are deemed to be Affiliates may be resold without 
registration as provided for by Rule 145 under the Securities Act, or as 
otherwise permitted.  The term Affiliate is defined to include any person who, 
directly or indirectly, controls, or is controlled by, or is under common 
control with MID STATES at the time the Merger Agreement is submitted for 
approval by a vote of the shareholders of MID STATES Common Stock.  Each 
Affiliate who desires to resell the BANC ONE Common Stock received in the 
Merger must sell such BANC ONE Common Stock either (i) pursuant to an effective 
registration statement under the Securities Act, (ii) in accordance with the 
applicable provisions of Rule 145 under the Securities Act or (iii) in a 
transaction which, in the opinion of counsel for such Affiliate or as described 
in a "no-action" or interpretive letter from the Staff of the Commission, in 
each case reasonably satisfactory in form and substance to BANC ONE, states 
that such resale is exempt from the registration requirements of the Securities 
Act.

Rule 145(d) requires that persons deemed to be Affiliates resell their BANC ONE 
Common Stock pursuant to certain of the requirements of Rule 144 under the 
Securities Act if such BANC ONE Common Stock is sold within the first two years 
after the receipt thereof.  After two years, if such person is not an affiliate 
of BANC ONE and BANC ONE is current in the filing of its periodic securities 
law reports, a former Affiliate of MID STATES may freely resell the BANC ONE 
Common Stock received in the Merger without limitation.  After three years from 
the issuance of the BANC ONE Common Stock, if such person is not an affiliate 
of BANC ONE at the time of sale or for at least three months prior to such 
sale, such person may freely resell such BANC ONE Common Stock, without 
limitation, regardless of the status of BANC ONE's periodic securities law 
reports.

MID STATES has agreed to provide BANC ONE with a list of those persons who may 
be deemed to be Affiliates at the time of the Special Meeting.  MID STATES will 
use its best efforts to cause each such person to deliver to BANC ONE prior to 
the Effective Time a written agreement to the effect that no sale will be made 
of any shares of BANC ONE Common Stock received in the Merger by an Affiliate 
of MID STATES except (i) in accordance with the Securities Act and (ii) if, as 
it expects to do, BANC ONE utilizes pooling-of-interests accounting in 
accounting for the Merger, until such time as BANC ONE shall first publish the 
financial results of at least 30 days of post-merger combined operations of MID 
STATES and BANC ONE, provided that BANC ONE shall publish such results not 
later than four months from the Effective Time.  The certificates of BANC ONE 
Common Stock issued to Affiliates of MID STATES in the Merger may contain an 
appropriate restrictive legend, and appropriate stop transfer orders may be 
given to the transfer agent for such certificates.

Accounting Treatment

BANC ONE expects to account for the acquisition of MID STATES as a 
pooling-of-interests.


                       COMPARATIVE RIGHTS OF SHAREHOLDERS

Description of BANC ONE Stock

General.  The authorized capital stock of BANC ONE consists of 600,000,000 
shares of BANC ONE Common Stock and 35,000,000 shares of Preferred Stock, 
without par value ("Preferred Stock"), divided into 10,000,000 shares of Class 
A Preferred Stock, 1,000,000 shares of Class B Convertible Preferred Stock 
("Class B Preferred Stock") and 24,000,000 shares of Class C Preferred Stock of 
which the $3.50 Cumulative Convertible Preferred Stock constitutes a series 
("Series C Preferred Stock").  As of December 31, 1993, there were issued and 
outstanding 5,000,000 shares of Series C Preferred Stock and 380,687,187 shares 
of BANC ONE Common Stock.

The following summary of the terms of BANC ONE's capital stock does not purport 
to be complete and is qualified in its entirety by reference to the applicable 
provisions of the Ohio General Corporation Law and BANC ONE's Articles.

Common Stock.  Holders of BANC ONE Common Stock are entitled to receive 
dividends out of funds legally available therefor as and if declared by the 
Board of Directors, provided that, so long as any shares of Preferred Stock are 
outstanding, no dividends (other than dividends payable in BANC ONE Common 
Stock) or other distributions (including redemptions and purchases) may be made 
with respect to the BANC ONE Common Stock unless full cumulative dividends on 
the shares of Preferred Stock have been paid.

Holders of shares of BANC ONE Common Stock are entitled to one vote for each 
share for the election of directors and on all other matters.  Holders of 
BANC ONE Common Stock vote together as a class with holders of Class B 
Preferred Stock.  Generally, holders of Series C Preferred Stock have no voting 
rights.

The issued and outstanding shares of BANC ONE Common Stock are fully paid and 
nonassessable.  The holders of BANC ONE Common Stock are not entitled to 
preemptive rights or conversion or redemption rights.  The BANC ONE Common 
Stock does not have cumulative voting rights in the election of directors.

In the event of the voluntary or involuntary dissolution, liquidation or 
winding up of BANC ONE, holders of BANC ONE Common Stock will be entitled to 
receive, pro rata, after satisfaction in full of the prior rights of creditors 
(including holders of BANC ONE's indebtedness) and holders of Preferred Stock, 
all the remaining assets of BANC ONE available for distribution.

Preferred Stock.  The Board of Directors has the authority to issue each class 
of Preferred Stock in one or more series and to fix the designations, number of 
shares, dividends, redemption rights, sinking fund requirements, liquidation 
prices, conversion rights and other rights, qualifications, limitations or 
restrictions thereon (except voting rights) as the Board of Directors may from 
time to time be permitted by law to fix or change.

Currently, there are outstanding shares of Series C Preferred Stock.  Holders 
of Series C Preferred Stock are entitled to receive out of funds legally 
available therefor cumulative cash dividends at the annual rate of $3.50 per 
share payable quarterly on the last day of March, June, September and December 
in each year.

In the event that full cumulative dividends on outstanding shares of Series C 
Preferred Stock have not been paid, no dividends may be declared or paid on, 
and no amounts may be set aside or applied to the redemption or purchase of, 
any shares of BANC ONE Common Stock or any other shares of capital stock of 
BANC ONE ranking junior to shares of Series C Preferred Stock.

Upon the voluntary or involuntary dissolution, liquidation or winding up of 
BANC ONE, holders of Series C Preferred Stock are entitled to receive a 
preferential distribution of $50 per share plus accrued and unpaid dividends, 
if any.

Generally holders of shares of Series C Preferred Stock have no voting rights.  
The approval of a majority of the outstanding shares of Series C Preferred 
Stock voting together as a class is required in order to amend BANC ONE's 
Articles to affect adversely the rights of the holders of the Series C 
Preferred Stock or to take any action that would result in the creation of or 
an increase in the number of authorized shares senior or superior with respect 
to dividends or upon liquidation to the Series C Preferred Stock.  Holders of 
Series C Preferred Stock also have the right to elect two additional directors 
during any period in which dividends on Series C Preferred Stock are 
cumulatively in arrears in the amount of six or more full quarterly dividends.

At the option of the holder of any shares of Series C Preferred Stock, such 
shares may be converted into shares of BANC ONE Common Stock at the conversion 
rate then in effect.  The present conversion rate is    1.75360     shares of
BANC ONE Common Stock for each share of Series C Preferred Stock and is 
subject to adjustment for stock dividends, subdivisions, splits (the 
conversion rate has been adjusted to reflect the 5 shares for 4 shares common 
stock split declared by Banc One's Board of Directors on July 20, 1993 and 
payable August 31, 1993 to shareholders of record on August 3, 1993) and 
combinations and any distribution of rights or warrants to purchase BANC ONE 
Common Stock at a price per share less than the BANC ONE Common Stock's then-
current market value.

The issued shares of Series C Preferred Stock may be redeemed, in whole or in 
part, by BANC ONE at its election at any time after April 15, 1995, at a 
redemption price of $52.10 per share during the period from April 15, 1995, to 
but not including March 31, 1996, and thereafter at the redemption prices 
during the 12-month periods beginning on March 31 of the years shown below, 
plus accrued and unpaid dividends, if any.

           Year                                    Redemption Price

           1996  . . . . . . . . . . . . . . . .        $51.75

Special Voting Requirements for Certain Transactions

Article Eleventh of BANC ONE's Articles incorporates, to a large extent, the 
provisions of the Ohio control share acquisition statute (Section 1701.831 of 
the Ohio Revised Code).  Article Eleventh sets forth procedures for obtaining 
shareholder consent of "control share acquisitions" subject to the right of the 
Board of Directors to screen out proposals that do not meet certain standards 
set forth in Article Eleventh.  Article Eleventh defines a "control share 
acquisition" as any acquisition, directly or indirectly, of shares of BANC ONE 
which, when added to all other shares of BANC ONE owned or controlled by the 
acquiror, would entitle the acquiror, alone or with others, to exercise or 
direct the exercise of voting power in BANC ONE in the election of directors 
within any of the following ranges of voting power:  (a) one-fifth or more but 
less than one-third; (b) one-third or more but less than a majority; and (c) a 
majority or more.  A bank, broker, nominee, trustee, or other person who 
acquires shares in the ordinary course of business for the benefit of others in 
good faith and not for the purpose of circumventing Article Eleventh shall, 
however, be deemed to have voting power only of shares in respect of which such 
person would be able to exercise or direct the exercise of votes without 
further instruction from others at a meeting of shareholders called under 
Article Eleventh.  A control share acquisition which meets certain criteria set 
forth in Article Eleventh as determined by the Board of Directors must be 
presented to a meeting of the shareholders of BANC ONE and approved by the 
affirmative vote of both (a) a majority of the voting power represented at the 
meeting and (b) a majority of that portion of such voting power excluding any 
"interested shares"; that is, those shares held by the acquiring person, 
executive officers of BANC ONE and employees of BANC ONE who are also 
directors.  Article Eleventh may be amended by a vote of 85% of the votes 
entitled to be cast by all holders of voting stock.

BANC ONE's Articles also include a "fair price" provision which is designed to 
provide reasonable assurances to shareholders that in the event any shareholder 
or group of shareholders acquires 20% or more of BANC ONE's voting stock (the 
"Acquiror") and then seeks to acquire all or part of the remaining voting stock 
through a merger or other transaction which would force a change or termination 
of the other shareholders' ownership interests (a "Business Combination"), such 
other shareholders must receive consideration at least equivalent to that paid 
by the Acquiror in acquiring its 20% stock interest, unless the Business 
Combination is approved either (i) by a majority of directors who are unrelated 
to the Acquiror or (ii) by the affirmative vote of 75% of all the votes 
entitled to be cast by all holders of voting stock and 67% of the votes 
entitled to be cast by all holders of voting stock held by shareholders other 
than the Acquiror ("Special Shareholder Vote").

This provision operates by requiring that after an Acquiror emerges, any 
Business Combination which has the effect of requiring shareholders to 
surrender their shares must satisfy one of the following conditions:

    (a)  Fair Consideration to Shareholders.  The terms of the Business 
         Combination must provide for payment of consideration which is at 
         least equivalent to the highest price paid to other shareholders by 
         the Acquiror in acquiring its 20% stock position and must be approved 
         by shareholders as otherwise required by applicable law; or

    (b)  Unrelated Director Approval.  The Business Combination must be 
         approved as fair to shareholders by a majority of the directors who 
         are not affiliated with the Acquiror and who were directors before the 
         Acquiror acquired its 20% stock position or who were nominated or 
         elected to succeed such directors by the other unaffiliated directors 
         ("Unrelated Directors") and must be approved by shareholders as 
         otherwise required by applicable law; or

    (c)  Special Shareholder Vote.  The Business Combination must be approved 
         by a Special Shareholder Vote.


The Article containing this provision may be amended only by a vote of 85% of 
the votes entitled to be cast by all holders of voting stock, unless the 
amendment is approved unanimously by the Unrelated Directors, in which case 
only majority shareholder approval would be required.

Chapter 1704 of the Ohio Revised Code (the "Ohio Statute") is similar to the 
"fair price" provision contained in BANC ONE's Articles.  The Ohio Statute 
prohibits an "Issuing Public Corporation" from engaging in a "Chapter 1704 
Transaction" with an "Interested Shareholder" for a period of three years 
following the date on which the person becomes an "Interested Shareholder" 
unless, prior to such date, the directors of the "Issuing Public Corporation" 
approve either the "Chapter 1704 Transaction" or the acquisition of shares 
pursuant to which such person became an "Interested Shareholder."  An "Issuing 
Public Corporation" is an Ohio corporation with 50 or more shareholders which 
has its principal place of business, principal executive offices or substantial 
assets within the State of Ohio.  BANC ONE is currently an Issuing Public 
Corporation.  An "Interested Shareholder" is any person who is the beneficial 
owner of a sufficient number of shares to allow such person, directly or 
indirectly, alone or with others, including affiliates and associates, to 
exercise or direct the exercise of 10% of the voting power of the Issuing 
Public Corporation.  A "Chapter 1704 Transaction" includes any merger, 
consolidation, combination or majority share acquisition between or involving 
an Issuing Public Corporation and an Interested Shareholder or an affiliate or 
associate of an Interested Shareholder.  A Chapter 1704 Transaction also 
includes certain transfers of property, dividends and issuance or transfers of 
shares, from or by an Issuing Public Corporation or a subsidiary of an Issuing 
Public Corporation to, with or for the benefit of an Interested Shareholder or 
an affiliate or associate of an Interested Shareholder unless such transaction 
is in the ordinary course of business of the Issuing Public Corporation on 
terms no more favorable to the Interested Shareholder than those acceptable to 
third parties as demonstrated by contemporaneous transactions.  Finally, 
Chapter 1704 Transactions include certain transactions which (i) increase the 
proportionate share ownership of an Interested Shareholder, (ii) result in the 
adoption of a plan or proposal for the dissolution, winding up of the affairs 
or liquidation of the Issuing Public Corporation if such plan is proposed by or 
on behalf of the Interested Shareholder, or (iii) pledge or extend the credit 
or financial resources of the Issuing Public Corporation to or for the benefit 
of the Interested Shareholder.

After the initial three-year moratorium has expired, an Issuing Public 
Corporation may engage in a Chapter 1704 Transaction if (i) the acquisition of 
shares pursuant to which the person became an Interested Shareholder received 
the prior approval of the board of directors of the Issuing Public Corporation, 
(ii) the Chapter 1704 Transaction is approved by the affirmative vote of the 
holders of shares representing at least a majority of the voting power of the 
Issuing Public Corporation and by the holders of at least a majority of voting 
shares which are not beneficially owned by an Interested Shareholder or an 
affiliate or associate of an Interested Shareholder, or (iii) the Chapter 1704 
Transaction meets certain statutory tests designed to ensure that it be 
economically fair to all shareholders.

Comparison of BANC ONE Common Stock and MID STATES Common Stock

The rights of shareholders of BANC ONE are governed by BANC ONE's Articles and 
Code of Regulations and the applicable provisions of the Ohio law, while the 
rights of the shareholders of MID STATES are governed by MID STATES' 
Certificate and By-laws and the applicable provisions of the DGCL.  If the 
holders of MID STATES Common Stock approve the Merger Agreement and the Merger 
is subsequently consummated, holders of MID STATES Common Stock will become 
holders of BANC ONE Common Stock.  The following comparison of the rights of 
holders of MID STATES Common Stock and BANC ONE Common Stock is based on 
current terms of the governing documents of the respective companies, and on 
the current provisions of applicable state law.

The rights of holders of MID STATES Common Stock and holders of BANC ONE Common 
Stock are similar in several respects:  each shareholder is entitled to one 
vote for each share held on all matters submitted to a vote of shareholders 
(although holders of MID STATES Common Stock are entitled to exercise 
cumulative voting in the election of directors), each shareholder is entitled 
to receive pro rata any assets distributed to shareholders upon liquidation, 
dissolution or winding up of the affairs of the company (after all creditors 
have been satisfied and requisite preferential amounts are paid to the holders 
of outstanding preferred stock).  Although it is impracticable to note all the 
differences between Ohio law and the DGCL generally and all of the differences 
between the applicable governing documents of BANC ONE and MID STATES, the 
following is intended to be a summary of certain significant differences 
between the rights of holders of BANC ONE Common Stock and the rights of 
holders of MID STATES Common Stock.

Election and Removal of Directors.  MID STATES' directors are elected by 
cumulative voting.  This means that in an election of directors, holders of MID 
STATES Common Stock may give one candidate a number of votes equal to the 
number of directors to be elected multiplied by the number of shares owned by 
the shareholder, or distribute the number of votes among any number of 
candidates.  MID STATES' entire Board of Directors or any lesser number may be 
removed, with or without cause, by a vote of the holders of the majority of the 
shares then entitled to vote at an election of directors, except that no 
director may be removed if the votes cast against his removal would be 
sufficient to elect such director if voted cumulatively at an election of 
directors at which the same total number of votes were cast and the entire 
board were then being elected.  Cumulative voting makes it more likely that 
sizable minority shareholders could elect minority directors even if opposed by 
the other shareholders.  Cumulative voting is not allowed in the election of 
directors of BANC ONE.     All of the directors of MID STATES and BANC ONE are 
elected by the shareholders each year and may be removed with or without cause 
by the shareholders.    

Dividends.  Under Ohio law, dividends may be paid out of surplus, including 
both earned surplus and capital surplus, in cash, property or shares of the 
corporation, provided that such dividend payments are not in violation of the 
rights of any other class of securities and are not made when the corporation 
is insolvent or there is reasonable ground to believe that by such payment it 
will be rendered insolvent.  A Delaware corporation may pay dividends out of 
any surplus and, if it has no surplus, out of any net profits for the fiscal 
year in which the dividend was declared or for the preceding fiscal year; 
provided that such payment may not be made from such net profit if capital 
shall have been reduced by depreciation, losses or otherwise below the amount 
of capital represented by all classes of shares having a preference upon the 
distribution of assets.  The payment of dividends by bank holding companies 
also is subject to certain regulatory constraints.  Dividends paid by both BANC 
ONE and MID STATES are subject to federal income tax to the extent of the 
distributing corporation's current and accumulated earnings and profits.  
However, it is suggested that in connection with voting on the Merger, 
shareholders contact their tax advisors to determine the tax consequences of 
the Merger to them.

Supermajority and Fair Price Provisions.  MID STATES' Certificate contains 
provisions similar to the provisions of BANC ONE's Articles relating to control 
share acquisitions and fair price provisions for business combinations.  BANC 
ONE's Articles contain provisions requiring a supermajority vote for certain 
business combinations.  See "COMPARATIVE RIGHTS OF SHAREHOLDERS--Special Voting 
Requirements for Certain Transactions."  Although Delaware law generally 
requires the affirmative vote of the holders of a majority of the shares of 
each class entitled to vote to approve a merger, consolidation, share exchange 
or sale, lease, exchange or other disposition of all or substantially all of 
MID STATES' assets, MID STATES' Certificate requires the approval of certain 
interested shareholder transactions by not less than 75% of MID STATES' 
outstanding shares entitled to vote, unless certain alternative requirements 
are satisfied.  In addition, in the event of a merger, consolidation or sale of 
MID STATES or any subsidiary thereof, with or to a corporation, person or 
entity, which owns, directly or indirectly, ten percent or more of the 
outstanding shares of MID STATES ("Ten Percent Owner"), each holder of MID 
STATES Common Stock who properly opposes such transaction is entitled to 
receive a price for his, her or its shares equal to the highest price paid by 
such Ten Percent Owner for shares of MID STATES purchased in the two-year 
period prior to the consummation of such transaction.

In addition to being subject to the laws of Delaware and Ohio, respectively, 
both MID STATES and BANC ONE, as bank holding companies, are subject to various 
provisions of federal law with respect to mergers, consolidations and certain 
other corporate transactions.

Evaluation of Tender Offers and Business Combinations.  In evaluating an 
acquisition proposal, Ohio law includes a provision which permits directors, in 
determining whether any matter is in the best interests of the corporation, to 
take into consideration the interests of the corporation's employees, 
suppliers, creditors and customers, the economy of the state and the nation, 
community and societal considerations and the long-term and short-term 
interests of the corporation and its shareholders, including the possibility 
that such interests may be best served by the continued independence of the 
corporation.  No similar provision is included in the DGCL or MID STATES' 
Certificate.

Amendment of Governing Documents.  BANC ONE's Articles may be amended by the 
affirmative vote of the holders of a majority of the voting power of BANC ONE, 
except that amendments to the "control share acquisition" and "fair price" 
provisions require a supermajority vote.  See "COMPARATIVE RIGHTS OF 
SHAREHOLDERS--Special Voting Requirements for Certain Transactions."  The Code 
of Regulations of BANC ONE may only be amended by the affirmative vote of a 
majority of the voting power represented by the outstanding voting stock of 
BANC ONE present in person or by proxy at an annual or special meeting called 
for such purpose.

MID STATES' Certificate may be amended by the affirmative vote of the holders 
of a majority of the outstanding shares of MID STATES' voting stock, except 
that amendments to the provision providing for supermajority voting and any 
amendment which provides for any change to Sections Fifth, Sixth and Ninth of 
MID STATES' Articles require the affirmative vote of three-fourths of the 
outstanding shares of MID STATES' voting stock.  The DGCL provides that 
shareholders of a corporation may amend its by-laws and that a corporation may, 
in its certificate of incorporation, also confer such power upon its Board of 
Directors.  MID STATES' Certificate explicitly confers upon the MID STATES' 
Board the power to amend MID STATES' by-laws.  Accordingly, both the MID 
STATES' Board and its shareholders may amend MID STATES' by-laws by a majority 
vote, except that amendments by MID STATES' shareholders to provisions in MID 
STATES' by-laws with respect to the number of directors and the filling of 
director vacancies require the affirmative vote of not less than three-fourths 
of the outstanding shares of MID STATES' voting stock.

Appraisal Rights.  Under the DGCL, appraisal or dissenters' rights are 
available only in connection with statutory mergers or consolidations.  Even in 
such cases, unless the certificate of incorporation otherwise provides, the 
DGCL does not recognize dissenters' rights for any class or series of stock 
which is either listed on a national securities exchange or held of record by 
more than 2,000 shareholders except that appraisal rights are available for 
holders of stock who, by the terms of the merger or consolidation, are required 
to accept anything except (i) stock of the corporation surviving or resulting 
from the merger of consolidation, (ii) shares which at the effective time of 
the merger or consolidation are either listed on a national securities exchange 
or held of record by more than 2,000 shareholders, (iii) cash in lieu of 
fractional shares of stock described in the foregoing clauses (i) and (ii), or 
(iv) any combination of stock and cash in lieu of fractional shares described 
in the foregoing clauses (i), (ii) or (iii).  MID STATES has less than 2,000 
shareholders and although a local brokerage firm attempts to make a market in 
MID STATES Common Stock, MID STATES Common Stock is not listed on any national 
securities exchange.  Therefore, holders of MID STATES Common Stock will be 
entitled under the DGCL to appraisal rights in connection with the Merger.  See 
"VOTING AND MANAGEMENT INFORMATION--Rights of Dissenting Shareholders."

Under Ohio law, dissenting shareholders are entitled to appraisal rights in 
connection with the lease, sale, exchange, transfer or other disposition of all 
or substantially all of the assets of a corporation and in connection with 
certain amendments to its articles of incorporation.  In addition, shareholders 
of an Ohio corporation being merged into a new corporation are also entitled to 
appraisal rights.  Shareholders of an acquiring corporation are entitled to 
appraisal rights in a merger, combination or majority share acquisition in 
which such shareholders are entitled to voting rights.

Repurchases.  Under the DGCL, a corporation may repurchase or redeem its shares 
only if such purchase does not impair capital.  However, a corporation may 
redeem preferred stock out of capital if such shares will be retired upon 
redemption and the stated capital of the corporation is thereupon reduced in 
accordance with the DGCL.  Under Ohio law, a corporation may purchase or redeem 
its own shares if authorized to do so by its articles of incorporation or under 
certain other circumstances but may not do so only if immediately thereafter 
its assets would be less than its liabilities plus its stated capital, if any, 
or if the corporation is insolvent or would be rendered insolvent by such a 
purchase or redemption.  Article Sixth of BANC ONE's Articles permits BANC ONE 
to repurchase or redeem shares to the extent permitted by law.

Indemnification.  The DGCL provides that a director, employee, officer or agent 
of a corporation may be indemnified against liability (other than in an action 
by or in the right of a corporation) and other costs incurred by such person in 
connection with such proceedings, provided such person acted in good faith and 
in a manner such person reasonably believed to be in and not opposed to, the 
best interests of the corporation and, with respect to any criminal 
proceedings, had no reason to believe the conduct was unlawful.  For actions or 
suits brought by or in the name of the corporation, the DGCL provides that a 
director, employee, officer or agent of a corporation may be indemnified 
against expenses by such person in connection with such proceeding if such 
person acted in good faith and in a manner such person reasonably believed to 
be in and not opposed to, the best interests of the corporation except that if 
such person is adjudged to be liable to the corporation, such person can be 
indemnified if and only to the extent that a court shall determine that despite 
the adjudication of liability, in view of all the circumstances of the case, 
such person is fairly and reasonably entitled to indemnity for such expenses as 
the court shall deem proper.  The DGCL permits a corporation to advance 
expenses incurred by an officer or director in defending any action prior to 
the disposition of such action upon a receipt of an undertaking by or on behalf 
of such officer or director to repay such amount if it is ultimately determined 
that such officer or director is not entitled to be indemnified by the 
corporation.  MID STATES' By-laws provide that MID STATES must indemnify all 
persons whom it is permitted to indemnify under the DGCL.

The DGCL allows a corporation to provide, in its certificate of incorporation, 
a provision which limits or eliminates the personal liability of a director to 
the corporation and its shareholders for monetary damages for such person's 
breach of fiduciary duty, provided that such provision may not so limit a 
director's liability (i) for a breach of his duty of loyalty to the 
corporation; (ii) for acts or omissions not in good faith or involving 
intentional misconduct or a knowing violation of law; (iii) for unlawful 
payments of dividends, certain stock repurchases or redemptions; or (iv) for 
any transaction from which the director derived an improper personal benefit.  
These provisions have the effect of protecting a corporation's directors 
against personal liability from breaches of their duty of care, including 
liability for gross negligence under Delaware law.  MID STATES' By-laws contain 
a provision eliminating such liability to the extent permitted under the DGCL.

Under Ohio law, Ohio corporations are authorized to indemnify directors, 
officers, employees and agents within prescribed limits and must indemnify them 
under certain circumstances.  Ohio law does not provide statutory authorization 
for a corporation to indemnify directors and officers for settlements, fines or 
judgments in the context of derivative suits.  However, it provides that 
directors (but not officers) are entitled to mandatory advancement of expenses, 
including attorneys' fees, incurred in defending any action, including 
derivative actions, brought against the director, provided the director agrees 
to cooperate with the corporation concerning the matter and to repay the amount 
advanced if it is proved by clear and convincing evidence that his or her act 
or failure to act was done with deliberate intent to cause injury to the 
corporation or with reckless disregard for the corporation's best interests.  
Ohio law does not authorize payment of expenses or judgments to an officer or 
other agent after a finding of negligence or misconduct in a derivative suit 
absent a court order.  Indemnification is required, however, to the extent such 
person succeeds on the merits.  In all other cases, if a director or officer 
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 company, indemnification is 
discretionary except as otherwise provided by a company's articles, code of 
regulations or by contract except with respect to the advancement of expenses 
of directors.  The statutory right to indemnity is not exclusive in Ohio.  Ohio 
law provides express authority for Ohio corporations to procure not only 
insurance policies, but also to furnish protection similar to insurance, 
including trust funds, letters of credit and self-insurance, or to provide 
similar protection such as indemnity against loss of insurance.

Unlike Delaware law, Ohio law has codified the traditional business judgment 
rule.  Ohio law provides that the business judgment presumption of good faith 
may only be overcome by clear and convincing evidence, rather than the 
preponderance of the evidence standard applicable in most states.  Further, 
Ohio law provides specific statutory authority for directors to consider, in 
addition to the interests of the corporation's shareholders, other factors such 
as the interest of the corporation's employees, suppliers, creditors and 
customers; the economy of the state and nation; community and societal 
considerations; the long-term and short-term interests of the corporation and 
its shareholders; and the possibility that these interests may be best served 
by the continued independence of the corporation.

                   B.  INFORMATION ABOUT BANC ONE CORPORATION

General -- Business.

BANC ONE is a multi-bank holding company with bank subsidiaries in Arizona, 
California, Colorado, Ohio, Illinois, Indiana, Kentucky, Michigan, 
   Oklahoma,     Texas, Utah, West Virginia and Wisconsin.  At 
   December 31,     1993, BANC ONE had consolidated total assets of 
   $79.9 billion    , consolidated total deposits of approximately 
   $60.9 billion     and consolidated total shareholders' equity of 
approximately    $7.0 billion.  At December 31,     1993, BANC ONE 
ranked eighth among the nation's publicly owned bank holding companies 
in terms of period-end assets and at December 31, 1993, BANC ONE ranked 
sixth among the nation's publicly owned bank holding companies in terms of 
period-end common equity.  For the    year     ended    December 31,     
1993, BANC ONE's return on average assets was    1.53%    

As of    December 31,     1993, BANC ONE owned indirectly all of the 
outstanding stock of    82     commercial banks (the "affiliate banks").  
Except for Bank One, Texas, N.A., BANC ONE had no single affiliate bank 
comprising in excess of 20% of its consolidated assets at    December 31,     
1993.         BANC ONE also owns subsidiaries which offer services in the areas 
of mortgage banking, credit card processing, consumer finance, equipment 
leasing, fiduciary and trust services, venture capital, credit life 
insurance, brokerage and data processing.

Since its formation in 1968, BANC ONE has acquired over 125 banking 
institutions and the number of banking offices of its affiliate banks has 
increased from 24 to over 1,300.  BANC ONE anticipates that it will continue to 
expand by acquisition in the future.  BANC ONE is frequently in discussions 
regarding possible acquisitions.  See "Recent Developments" for information 
with respect to pending and potential acquisitions.

BANC ONE is a legal entity separate and distinct from its affiliate banks and 
its nonbanking subsidiaries.  Accordingly, the right of BANC ONE, and thus the 
right of BANC ONE's creditors and shareholders, to participate in any 
distribution of the assets or earnings of any affiliate bank or other 
subsidiary is necessarily subject to the prior claims of creditors of the 
affiliate bank or subsidiary, except to the extent that claims of BANC ONE in 
its capacity as a creditor may be recognized.  The principal source of 
BANC ONE's revenues is dividends and fees from its affiliates.  See "Certain 
Regulatory Matters" for a discussion of regulatory restrictions on the ability 
of the affiliate banks to pay dividends to BANC ONE.

Recent Developments.

   
In recent years, BANC ONE has pursued an active acquisition program.  The 
following is a list of announced significant acquisitions that have not been 
consummated as of the date of this Prospectus and Proxy Statement.

    Liberty National Bancorp, Inc., a multi-bank holding company headquartered 
    in Louisville, Kentucky with assets of approximately $4.9 billion as of 
    December 31, 1993, which BANC ONE will acquire for approximately 24 million 
    shares of BANC ONE Common Stock.

BANC ONE has also announced three other acquisitions which are not material in 
the aggregate.  In addition, BANC ONE has recently terminated its pending 
acquisitions of FirsTier Financial, Inc., a multi-bank holding company 
headquartered in Omaha, Nebraska with assets of approximately $3.1 billion as 
of December 31, 1993, and Nebraska Capital Corporation, a single bank holding 
company headquartered in Lincoln, Nebraska with assets of approximately $95 
million as of December 31, 1993.
    

BANC ONE continues to explore opportunities to acquire banks and nonbank 
companies permitted by the Bank Holding Company Act of 1956.  Discussions are 
continually being carried on relating to the acquisition of bank-related 
companies and other banks.  It is not presently known whether, or on what 
terms, such discussions will result in further acquisitions.  BANC ONE's 
acquisition strategy is flexible in that it does not require BANC ONE to effect 
specific acquisitions so as to enter certain markets or to attain specified 
growth levels.  Rather than being market driven or size motivated, BANC ONE's 
acquisition strategy reflects BANC ONE's willingness to consider potential 
acquisitions wherever and whenever such opportunities arise based on the 
then-existing market conditions and other circumstances.  Banks to be acquired 
must be of sufficient size to support and justify having management of a 
caliber capable of making lending and other management decisions at the local 
level under BANC ONE's operating philosophy.  BANC ONE also is willing from 
time to time to acquire a smaller bank when it can be acquired through a 
reorganization into an existing affiliate.  BANC ONE's interest in the 
acquisition of non-bank companies has been limited to bank-related services 
with which BANC ONE already has familiarity.  BANC ONE's acquisitions may be 
made by the exchange of stock, through cash purchases, and with other 
consideration.

Other than as described above, BANC ONE does not currently have any definite 
understandings or agreements for any acquisitions material to BANC ONE.  
However, BANC ONE anticipates that it will continue to expand by acquisition in 
the future.

Certain Regulatory Matters

General

BANC ONE is subject to the supervision of, and to regular inspection by, the 
Federal Reserve.  BANC ONE's principal banking subsidiaries are organized as 
national banking associations, which are subject to regulation by the 
Comptroller of the Currency (the "Comptroller").  In addition, various state 
authorities regulate BANC ONE's state banking subsidiaries.  Furthermore, the 
various banking subsidiaries are subject to regulation by the Federal Deposit 
Insurance Corporation (the "FDIC") and other federal bank regulatory bodies.  
In addition to banking laws, regulations and regulatory agencies, BANC ONE and 
its subsidiaries and affiliates are subject to various other laws, regulations 
and regulatory agencies, all of which directly or indirectly affect BANC ONE's 
operations, management and ability to make distributions.  The following 
discussion summarizes certain aspects of those laws and regulations that affect 
BANC ONE.

Proposals to change the laws and regulations governing the banking industry are 
frequently raised in Congress, in the state legislatures and before the various 
bank regulatory agencies.  The likelihood and timing of any changes and the 
impact such changes might have on BANC ONE and its subsidiaries are difficult 
to determine.

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.  This support may be required at 
times when a bank holding company may not be able to provide such support.  
Furthermore, 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 BANC ONE or 
related to FDIC assistance provided to a subsidiary in danger of default -- the 
other banking subsidiaries of BANC ONE may be assessed for the FDIC's loss, 
subject to certain exceptions.

BANC ONE's banks are affected by various state and federal laws and by the 
fiscal and monetary policies of the federal government and its agencies, 
including the Federal Reserve.  An important purpose of these policies is to 
curb inflation and control recessions through control of the supply of money 
and credit.  The Federal Reserve uses its powers to regulate reserve 
requirements of its member banks, the discount rate on its member bank 
borrowings, interest rates on time and savings deposits of its member banks, 
and to conduct open market operations in United States government securities so 
as to exercise control over the supply of money and credit.  These policies 
have a direct effect on the amount of bank loans and deposits and on the 
interest rates charged on loans and paid on deposits, with the result that 
federal policies have a material effect on bank earnings.  Policies which are 
directed toward increasing the supply of money and credit and reducing interest 
rates may have an adverse effect on bank earnings.  Future policies of the 
Federal Reserve and other authorities cannot be predicted, nor can their effect 
on future bank earnings be predicted.  Similarly, future changes in state and 
federal laws and wage, price and other economic restraints of the federal 
government cannot be predicted nor can their effect on future bank earnings be 
predicted.

Capital Requirements

The Federal Reserve, the FDIC  and the Comptroller have issued substantially 
similar minimum risk-based and leverage capital guidelines for 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 its financial condition or actual or anticipated 
growth.

The Federal Reserve risk-based guidelines applicable to BANC ONE define a 
two-tier capital framework.  Tier 1 capital consists of common and qualifying 
preferred shareholders' equity, minority interests less goodwill and certain 
other intangible assets, and one-half of investments in unconsolidated 
subsidiaries.

Tier 2 capital consists of mandatory convertible debt, subordinated and other 
qualifying term debt, preferred stock not qualifying as Tier 1 capital and the 
allowance for credit losses, subject to certain limitations less one-half of 
investments in unconsolidated subsidiaries.  The sum of Tier 1 and Tier 2 
capital represents qualifying total capital, at least 50% of which must consist 
of Tier 1 capital.  Risk-based capital ratios are calculated by dividing Tier 1 
and total capital by the sum of four categories of risk-weighted assets, such 
risk weights based primarily on relative credit risk.  The regulatory minimum 
qualifying total risk-based capital ratio is 8%, of which at least 4% must 
consist of Tier 1 capital.  BANC ONE's Tier 1 and total risk-based capital 
ratios under these guidelines at    December 31,     1993 were    10.51%     
and    14.19%,     respectively.

The leverage ratio is determined by dividing Tier 1 capital by adjusted 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%.  
BANC ONE's estimated leverage ratio at    December 31,     1993 was 
   8.66%.      Although BANC ONE has not been informed of any specific 
leverage ratio requirement applicable to it, management believes that BANC ONE 
meets its leverage ratio requirement.

Dividend Restrictions

Various federal and state statutory provisions limit the amount of dividends 
BANC ONE's affiliate banks can pay to BANC ONE without regulatory approval.  
The approval of the appropriate bank regulator is required for any dividend by 
a national bank or state member bank if the total of all dividends declared by 
the bank in any calendar year would exceed the total of its net profits, as 
defined by regulatory agencies, for such year combined with its retained net 
profits for the preceding two years.  In addition, a national bank or a state 
member bank may not pay a dividend in an amount greater than its net profits 
then on hand.  Under these provisions and various state law restrictions, 
BANC ONE's affiliate banks could have declared, as of December 31,    1993,     
without obtaining prior regulatory approval, aggregate dividends of approxi-
mately    $1.2 billion    .  In addition, federal bank regulatory authorities 
have authority to prohibit the affiliate banks from engaging in an unsafe or 
unsound practice in conducting their business.  The payment of dividends, 
depending upon the financial condition of the bank in question, could be deemed 
to constitute such an unsafe or unsound practice.  The ability of BANC ONE's 
affiliate banks to pay dividends in the future is presently, and could be 
further, influenced by bank regulatory policies and capital guidelines.

FDICIA

The Federal Deposit Insurance Corporation Improvement Act of 1991 (the 
"FDICIA"), which became law on December 19, 1991, revises several banking 
statutes, including the Federal Deposit Insurance Act, affecting bank 
regulation, deposit insurance and provisions for funding of the Bank Insurance 
Fund (the "BIF") administered by the FDIC.  Under FDICIA the bank regulators' 
authority to intervene is linked to the deterioration of a bank's capital 
level.  In addition, FDICIA places limits on real estate lending and brokered 
deposit activities, expands audit and reporting requirements, and imposes 
limitations and requirements on various banking functions.  BANC ONE believes 
that the deposit insurance and brokered deposit limitations under FDICIA will 
not have any material impact on the liquidity or funding of BANC ONE or its 
affiliate banks.

Deposit Insurance Assessments

The deposits of each of BANC ONE's banks are insured up to regulatory limits by 
the FDIC.  Accordingly, BANC ONE's banks are subject to deposit insurance 
assessments to maintain the Bank Insurance Fund (the "BIF") of the FDIC.

On September 14, 1992, the FDIC adopted regulations to implement a transitional 
risk-related insurance assessment system, starting January 1, 1993.  Under this 
system, the FDIC will place each insured bank in one of nine risk categories 
based on its level of capital and other relevant information (such as 
supervisory evaluations).  Each insured bank's insurance assessment rate will 
then be determined by the risk category in which it has been classified by the 
FDIC.  Under this transitional system, the average insurance assessment rate 
will be .254% per $100 of deposits.  However, there will be an eight basis 
point spread between the highest and lowest assessment rates, so that banks 
classified as strongest by the FDIC will be subject to a rate of $0.23 per $100 
of deposits and banks classified as weakest by the FDIC will be subject to a 
rate of $0.31 per $100 of deposits.  The FDIC has indicated that it expects 
that the majority of banks will be subject to an assessment rate of $0.23 per 
$100 of deposits (the same rate as under the current flat-rate assessment 
system).  However, the FDIC has also indicated that it expects to recommend 
that the permanent risk-related premium system, to be implemented in 1994, 
incorporate a wider differential between the highest and lowest assessment 
rates.

BANC ONE intends to continue its present policy of paying quarterly cash 
dividends to its shareholders so that dividends as a percentage of income will 
average between 35 and 40 percent of net income.  The timing and amount of 
future dividends will depend upon earnings, cash requirements, the financial 
condition of BANC ONE and its subsidiaries, applicable government regulations 
and other factors deemed relevant by the Board of Directors.  Certain debt 
instruments to which BANC ONE is a party limit its ability to pay dividends on 
BANC ONE Common Stock.  Under the most restrictive of these limitations, BANC 
ONE would have been permitted to pay cash dividends on BANC ONE Common Stock in 
excess of its    $1.0 billion     of retained earnings as of December 31, 
   1993.      As described under "Certain Regulatory Matters," various state 
and federal laws limit the ability of affiliate banks to pay dividends to 
BANC ONE.

shareholders for the Special Meeting.  Solicitation of proxies will be made in 
person, by mail, or by telephone or telegraph by present and former directors, 
officers and employees of MID STATES and First National for which no additional 
compensation will be paid.  Copies of the form of proxy and Notice and this 
Prospectus will be mailed to shareholders on or about    April    ,     1994.

Voting

The proxy accompanying this Prospectus    Proxy Statement     is solicited by 
the Board of Directors of MID STATES and, if properly executed and returned, 
will be voted in accordance with the instructions given therein.  IF NO 
INSTRUCTIONS ARE GIVEN, THE PROXY WILL BE VOTED IN FAVOR OF THE PROPOSAL TO 
APPROVE THE 
MERGER AGREEMENT.  Any proxy may be revoked at any time before 
it is voted by furnishing MID STATES with either written notice of revocation 
or a subsequently dated proxy or appearing at the Special Meeting and 
electing to vote in person.

The MID STATES Board has fixed the close of business on          , 1994,     
as the record date for the determination of shareholders entitled to notice of 
and to vote at the Special Meeting.  As of the record date,                
shares of MID STATES Common Stock were outstanding, each of which entitled its 
holder to one vote at the Special Meeting.  The affirmative vote of a majority 
of the outstanding shares of MID STATES Common Stock entitled to vote thereon 
is required for approval of the Merger Agreement.

The Directors of MID STATES have unanimously approved the Merger Agreement and 
each director has indicated an intention to vote all of his shares in favor of 
the Merger Agreement.

Rights of Dissenting Shareholders

Under Delaware law, appraisal or dissenters' rights are available in connection 
with statutory mergers or consolidations.  The DGCL provides that shareholders 
shall receive a notice at least 20 days prior to a meeting held for purposes of 
voting on a merger that appraisal rights are available and shall also receive a 
copy of Section 262 of the DGCL.  A shareholder wishing to exercise his or her 
appraisal rights shall deliver to the corporation, in advance of the merger 
vote, a written demand for appraisal.  A proxy or vote against the merger shall 
not constitute a demand under the DGCL.  Within 10 days after a merger is 
effective, the surviving or resulting corporation shall notify all shareholders 
who have demanded an appraisal and did not vote for or consent to the merger 
that the merger has become effective.  Within 120 days of the effective date of 
the merger, the surviving or resulting corporation or a shareholder who has 
demanded an appraisal may file a petition in a Court of Chancery demanding a 
determination of the value of the stock of all such shareholders.  Within 60 
days of the effective date of a merger, any shareholder may withdraw his or her 
previous demand for an appraisal and accept the terms of the merger.  Section 
262 of the DGCL is attached to this Prospectus and Proxy Statement as 
   Exhibit C.

                                                    EXHIBIT A

 
 April           , 1994
 
 Board of Directors
 
 Mid States Bancshares, Inc.
 501  15th Street
 Moline, Illinois  61265-2184
 
 Gentlemen:
 
 On December 21, 1993, we delivered to you our written opinion as
 to the fairness, from a financial point of view, to the holders
 of the outstanding common stock, par value $5.00 per share (the
 "Mid States Common Stock"), of Mid States Bancshares, Inc. ("Mid
 States") of the consideration to be received by such holders
 pursuant to the Agreement and Plan of Merger dated as of May 25,
 1993 by and among Mid States, Banc One Corporation ("Banc One")
 and Banc One Illinois Corporation, a wholly-owned subsidiary of
 Banc One (the "Merger Agreement").  The Merger Agreement
 provides for the merger of Mid States with and into Banc One
 Illinois Corporation (the "Merger") and provided for the
 conversion of each share of Mid States Common Stock into the
 right to receive, subject to certain limitations and procedures
 set forth in the Merger Agreement, 2.7225 shares of Banc One
 common stock, no par value ("Banc One Common Stock"), after
 giving effect to Banc One's five-share-for-four-share stock
 split on August 31, 1993 and ten percent stock dividend paid on
 March 4, 1994.  Our letter of December 31, 1993 expressed our
 opinion that, on the basis of the factors and subject to the
 conditions described in that letter, if the market value of the
 Banc One Common Stock to be received in respect of each share of
 Mid States Common Stock were $102.96 or higher, the
 consideration to be received by the holders of Mid States common
 stock pursuant to the Merger Agreement would be fair, from a
 financial point of view, to the holders of Mid States Common
 Stock.  In that letter, we expressed no opinion as to the
 fairness of such consideration in the event that the market
 value of the Banc One Common Stock to be received in respect of
 each share of Mid States Common Stock were less than $102.96.
 
 You have now requested our opinion as to the fairness, from a
 financial point of view, to the holders of Mid States Common
 Stock of the "Exchange Rate" set forth in the Second Agreement
 Amending Agreement and Plan of Merger, dated as of March 25,
 1994 (the "Second Amendment").  The Second Amendment provides
 that, at the time the Merger becomes effective (the "Effective
 Time") and subject to certain limitations and procedures set
 forth in the Merger Agreement and the amendments thereto, each
 of the not more than 311,560 shares of Mid States Common Stock
 that shall be issued and outstanding immediately prior to the
 Effective Time (excluding any shares held by Mid States as
 treasury shares) shall be converted into 2.917 shares of Banc
 One Common Stock (the "Exchange Rate").
 
 The Merger is subject to, among other things, approvals of the
 Board of Governors of the Federal Reserve System and the
 Illinois Commissioner of Banks and Trust Companies (which
 approvals have been granted), approval by the holders of a
 majority of the shares of Mid States Common Stock, and receipt
 of opinions to the effect that the Merger will qualify for
 treatment as a tax-free reorganization and a pooling-of-
 interests.
 
 Donaldson, Lufkin & Jenrette Securities Corporation, as part of
 its investment banking business, is regularly engaged in the
 valuation of businesses and their securities in connection with
 mergers and acquisitions, including bank holding company
 acquisitions, negotiated underwritings, competitive biddings,
 secondary distributions of listed and unlisted securities,
 private placements, and valuations for corporate and other
 purposes.  We were retained by Mid States to act as its
 exclusive financial advisor with respect to any sale, merger,
 consolidation, or other business combination, in one or a series
 of transactions, involving all or a substantial amount of the
 business, securities or assets of Mid States.  We have received
 and will receive compensation from Mid States in connection with
 our services, a significant portion of which is contingent upon
 the consummation of the Merger.
 
 At your direction, we solicited a limited number of
 institutions, including Banc One, to determine their interest in
 a possible business combination with Mid States.  Also at your
 direction, we ceased soliciting such interest of third parties
 at the time you determined to negotiate on an exclusive basis
 with Banc One, which negotiations led to execution of the Merger
 Agreement.
 
 In the ordinary course of our business we may actively trade the
 debt and equity securities of companies, including Mid States
 and Banc One, for our own account and for the accounts of
 customers and may hold a long or short position in such
 securities at any time.
 
 For purposes of this opinion and in connection with our review
 of the proposed transaction, we have, among other things:
 
    1.   Reviewed the Merger Agreement, the First Agreement
          Amending Agreement and Plan of Merger dated as of
          February 22, 1994, the Second Amendment, the
          prospectus and proxy statement dated as of December
          21, 1993 and the prospectus and proxy statement dated
          as of April ___, 1994 sent to the holders of Mid
          States Common Stock in connection with the proposed
          transaction;
 
    2.   Reviewed certain publicly available financial
          statements, both audited and unaudited, for Mid States
          and Banc One;
 
    3.   Reviewed certain financial statements and other
          financial and operating data concerning Mid States and
          Banc One prepared by their respective managements;
 
    4.   Reviewed certain financial projections of Mid States
          and Banc One, both on a stand-alone and on a combined
          basis, prepared by their respective managements;
 
    5.   Discussed certain aspects of the past and current
          business operations, results of regulatory
          examinations, financial condition and future prospects
          of Mid States and Banc One with certain members of the
          management of Mid States and Banc One;
 
    6.   Reviewed reported market prices and historical trading
          activity of Mid States Common Stock and Banc One
          Common Stock;
 
    7.   Reviewed certain aspects of the financial performance
          of Mid States and Banc One and compared such financial
          performance of Mid States and Banc One together with
          the stock market data relating to Mid States and Banc
          One with similar data available for certain other
          financial institutions and certain of their publicly
          traded securities;
 
    8.   Reviewed the financial terms, to the extent publicly
          available, of certain recent business combinations
          involving other  financial institutions;
 
    9.   Participated in discussions and negotiations among
          representatives of Mid States and Banc One and their
          financial and legal advisors; and
 
    10.  Conducted such other studies, analyses, and
          examinations as we deemed appropriate.
 
 We have relied upon and assumed without independent verification
 the accuracy and completeness of all of the financial and other
 information that has been provided to us by Mid States, Banc One
 and their respective representatives and of the publicly
 available information that was reviewed by us.  We have also
 relied upon the managements of both Mid States and Banc One as
 to the reasonableness and achievability of the financial and
 operating forecasts provided to us (and the assumptions and
 bases therefor).  In that regard, we have assumed that such
 forecasts, including without limitation projected costs savings
 and operating synergies resulting from the Merger, reflect the
 best currently available estimates and judgments of such
 respective managements and that such projections and forecasts
 will be realized in the amounts and in the time periods
 currently estimated by the managements of both Mid States and
 Banc One.  We have not independently verified and have relied on
 and assumed that the aggregate allowances for loan losses set
 forth in the balance sheets of each of Mid States and Banc One
 at December 31, 1993 are adequate to cover such losses and
 complied fully with applicable law, regulatory policy, and sound
 banking practice as of the date of such financial statements. 
 We were not retained to and we did not conduct a physical
 inspection of any of the properties or facilities of Mid States
 or Banc One, nor did we make any independent evaluation or
 appraisal of the assets, liabilities or prospects of Mid States
 or Banc One, were not furnished with any such evaluation or
 appraisal, and did not review any individual credit files.  We
 have also assumed that the Merger is, and will be, in compliance
 with all laws and regulations that are applicable to Mid States
 and Banc One.  We were informed by Mid States and have assumed
 for purposes of our opinion that the Merger will be recorded as
 a pooling of interests under generally accepted accounting
 principles.
 
 Our opinion is based solely upon the information available to us
 and the economic, market, and other circumstances as they exist
 as of the date hereof.  Events occurring after the date hereof
 could materially affect the assumptions used in preparing this
 opinion.  We have not undertaken to reaffirm or revise this
 opinion or otherwise comment upon any events occurring after the
 date hereof.
 
 In rendering our opinion, we have assumed that in the course of
 obtaining the necessary regulatory and governmental approvals
 for the proposed Merger, no restriction will be imposed on Banc
 One or the surviving corporation in the Merger that would have
 a material adverse effect on the contemplated benefits of the
 Merger.  We have also assumed that there would not occur any
 change in the applicable law or regulation that would cause a
 material adverse change in the prospects or operations of Banc
 One or the surviving corporation after the Merger.
 
 We are not expressing any opinion herein as to the prices at
 which shares of Banc One Common Stock may trade if and when they
 are issued or at any future time, nor does our opinion
 constitute a recommendation to any holder of Mid States Common
 Stock as to how such holder should vote with respect to the
 Merger Agreement at any meeting of holders of Mid States Common
 Stock.
 
 This letter is for the information of the Board of Directors of
 Mid States and is not to be quoted or referred to, in whole or
 in part, in any registration statement, prospectus, or proxy
 statement, or any other written document used in connection with
 the offer or sale of securities, nor shall this letter be used
 for any other purpose without our prior written consent;
 provided, however, that we hereby consent to the inclusion and
 reference to this opinion in any registration statement or proxy
 statement used in connection with the Merger so long as the
 opinion is quoted in full or attached as an exhibit to such
 registration statement or proxy statement.
 
 Subject to the foregoing and based on our experience as
 investment bankers, our activities as described above, and other
 factors we have deemed relevant, we are of the opinion as of the
 date hereof that the Exchange Rate is fair, from a financial
 point of view, to the holders of Mid States Common Stock.
 
                                  Very truly yours,
 
                                  DONALDSON, LUFKIN & JENRETTE

Opinion of Financial Advisor to Mid States

The Chicago Corporation has delivered its written opinion to Mid
States Board of Directors that, based upon and subject to the
various considerations set forth in the opinion dated            

        , 1994, the Exchange Ratio is fair from a financial point
of view to Mid States' shareholders as of the date of its
opinion. 
The Board of Directors has carefully and thoroughly reviewed the
materials and presentations of The Chicago Corporation and has
made
inquiries of The Chicago Corporation personnel as to the
methodology and the assumptions utilized in its analysis.  No
limitations were imposed by Mid States' Board of Directors upon
The
Chicago Corporation with respect to the investigations made or
procedures followed by it in rendering its opinion.

The full text of the opinion of The Chicago Corporation, which
sets
forth assumptions made, matters considered and limitations on the
review undertaken, is attached hereto as Exhibit B.  Mid States
shareholders are urged to read the opinion in its entirety.

The Chicago Corporation's opinion is directed only to the
Exchange
Ratio to be received in the Merger and does not constitute a
recommendation to any Mid States shareholder as to how such
shareholder should vote at the Annual Meeting.  The summary of
the
opinion of The Chicago Corporation set forth in this
Prospectus/Proxy Statement is qualified in its entirety by
reference to the full text of such opinion attached hereto as
Exhibit B.

Mid States retained The Chicago Corporation as its financial
advisor on the basis of the firm's reputation, experience and
familiarity with the banking industry and with merger and
acquisition transactions.  As part of its investment banking
business, The Chicago Corporation is regularly engaged in the
valuation of businesses in connection with mergers and
acquisitions, negotiated underwritings, secondary distribution of
listed and unlisted securities, private placements and valuations
for corporate and other purposes.

During the course of its engagement, and as a basis for arriving
at its opinion, The Chicago Corporation reviewed and analyzed
material bearing upon the financial and operating condition of
Mid States and Banc One and material prepared in connection with
the Merger, as follows: (i) the Merger Agreement; (ii) publicly
available information concerning Mid States and Banc One
including among other things annual reports on form 10-KSB for
Mid States and on form 10-K for Banc One for each of the last
five fiscal years ended; (iii) the nature and terms of recent
sale and merger transactions involving financial institutions
that The Chicago Corporation considered reasonably similar to Mid
States and Banc One in size, financial character, operating
character, historical performance and geographic market; (iv)
historical and current market data for Mid States Common Stock
and Banc One Common Stock and financial and other information
provided to The Chicago Corporation by management of Mid States
and Banc One, and (v) the Registration Statement and this
Prospectus/Proxy Statement.

These analyses are discussed in more detail below.  In addition,
The Chicago Corporation conducted meetings with members of senior
management of Mid States and Banc One for the purpose of
reviewing the future prospects of Mid States and Banc One.  The
Chicago Corporation evaluated the pro forma ownership of Banc One
Common Stock by Mid States shareholders, relative to the pro
forma contribution of Mid States' assets, liabilities, equity and
earnings of the proposed combined company.  The Chicago
Corporation also took into account its experience in other
transactions, as well as its knowledge of the banking industry
and its general experience in securities valuations.  In
rendering its opinion, The Chicago Corporation assumed without
independent verification, the accuracy and completeness of the
financial and other information and representations provided to
it by Mid States and Banc One.

The following is a summary of all material terms considered and
the analyses performed by The Chicago Corporation in rendering
its opinion during the course of its engagement in connection
with its              , 1994 opinion.

Net Present Value Analysis.  The Chicago Corporation prepared a
net present value analysis which indicated theoretical values for
Mid States based on return on average assets ranging between
1.00% and 1.50% and asset growth rates ranging between 2.00% and
10.00%.  The results of this analysis indicated a range of
theoretical values for Mid States between $68.05 per share (1.00%
return on average assets; 2.00% asset growth rate) and $138.52
per share (1.50% return on average assets; 10.00% asset growth
rate).  At a return on average assets ratio of 1.10%, which
approximated Mid States historical performance, theoretical
values ranged from $74.85 per share (2.00% asset growth rate) to
$101.58 per share (10.00% asset growth rate).  At an asset growth
rate of 4.00%, which approximated Mid States' historical
performance, theoretical values ranged from $73.55 per share
(1.00% return on average assets) to $110.32 per share (1.50%
return on average assets).  

Contribution Analysis.  The Chicago Corporation prepared a
contribution analysis showing the percentages of assets,
deposits, common equity, and 1992 and 1993 net income and
estimated 1994 and 1995 net income contributed to the combined
company on a pro forma basis by Mid States and Banc One, and
compared these percentages to the pro forma ownership of Banc
One.  This analysis showed that Mid States, as of December 31,
1993, would contribute 0.24% of pro forma consolidated total
assets, 0.27% of deposits, 0.29% of common equity, 0.23% of 1992
and 0.18% of 1993 net income and 0.19% of estimated 1994 and
0.18% estimated 1995 net income.  Based on the Banc One offer,
shareholders of Mid States would own approximately 0.24% of the
pro forma common shares outstanding of Banc One.

Comparable Transaction Analysis.  The Chicago Corporation
reviewed selected comparable merger and acquisition transactions. 
The following merger transactions were reviewed based on publicly
available data (the acquiror is named first and underlined,
followed by the seller):  AMCORE Financial, Inc., First State
Bancorp of Princeton; First Banks, Inc., First FSB of Proviso
Township; Mercantile Bancorporation, Inc., Mount Vernon Bancorp;
CNB Bancshares, Inc., South Central Illinois Bancorp; Old Kent
Financial Corporation, University Financial Corporation; Old
National Bancorp, Palmer Bancorp, Inc.; Banc One Corporation,
Jefferson Bancorp, Inc.; AMCORE Financial, Inc., Dixon Bancorp,
Inc.; Mercantile Bancorporation, Inc., Old National Bancshares;
Old National Bancorp, SBT Bancorp, Inc.; and AMCORE Financial,
Inc., Central of Illinois, Inc.  Transactions were selected on
the basis of comparability of absolute transaction value and the
perceived comparability of the markets served by the acquired
institutions to those of Mid States.  For the comparable
transactions, the multiple of price to trailing 12 months
earnings ranged from 8.2 to 22.5 with an average of 13.0.  At
March 25, 1994, the Banc One proposed purchase price represented
a multiple of price to trailing 12 months earnings of 14.5.

For the comparable transactions, the multiple of purchase price
to book value range from 0.95 to 1.95 with an average of 1.43. 
The Banc One offer to Mid States represented a multiple of price
to December 31, 1993 book value of 1.47.

Financial Implications to Mid States Shareholders.  The Chicago
Corporation prepared an analysis of the financial implications of
the Banc One offer to a Mid States Shareholder.  This analysis
indicated that on a pro forma equivalent basis a shareholder of
Mid States would achieve an increase in earnings per share, a
decrease in per share dividends and an increase in book value per
share as a result of the consummation of the Merger, assuming a
dividend payout ratio significantly higher than Mid States'
historical payout ratio.

Another analysis of the financial implications of the Banc One
offer kept Mid States' dividend payout ratio in line with
historical dividend payouts.  This analysis indicated that on a
pro forma equivalent basis a shareholder of Mid States would
achieve an increase in earnings per share, an increase in
dividends per share and a decrease in book value per share.

Comparative Shareholder Returns.  The Chicago Corporation
presented an analysis of comparative theoretical shareholder
returns for several scenarios, including Mid States remaining
independent, Mid States being acquired in 1994 and Mid States
being acquired in 1997.  This analysis, which was based on the
net present value of projected dividend streams and projected
1997 common stock valuations (using current price-to-trailing
twelve month earnings multiples), indicated total shareholders
returns of 11.4% for Mid States remaining independent, 31.7% for
a merger in 1997 and 38.2% based on the acceptance of an offer in
1994.  The Chicago Corporation also prepared an analysis of the
possible pricing of a merger transaction with certain other
Midwest-based bank holding companies using estimated 1994 net
income for Mid States and stock prices for selected companies and
assuming no earnings-per-share dilution for the buyer.  The
holding companies reviewed included:  AMCORE Financial, Inc.;
Banc One Corporation, Inc.; Commerce Bancshares, Inc.; First Bank
System, Inc.; First Midwest Bancorp; First of America Bank Corp.;
Firstbank of Illinois Co.; Firstar Corporation; Hawkeye
Bancorporation; Magna Group, Inc.; Mercantile Bancorporation,
Inc.; Northwest Illinois Bancorp; and Norwest Corporation.

Given the assumptions, the analysis indicated that these
companies could pay a high of $107.28 per share, a low of $66.12
per share and an average price of $81.72 per share for all of the
shares of Mid States.

A second analysis was conducted under the aforementioned
methodology with the 1994 net income of Mid States to include a
tax-effected 15% reduction in operating expenses.  Under that
assumption the previously listed companies could pay a high of
$131.87 per share, a low of $81.27 per share and an average price
of $100.45 per share for all the shares of Mid States.

Comparable Company Analysis.  The Chicago Corporation compared
the market price, market-to-book value and price-to-earnings
multiples of Banc One Common Stock with the individual market
multiples and averages of the following selected comparable
companies which it deemed to be reasonably similar to Banc One in
size, financial character, operating character, historical
performance and geographic market:  Banc One Corporation;
BankAmerica Corporation; Boatmen's Bancshares, Inc.; Citicorp;
Comerica Incorporated; First Bank System, Inc.; First Chicago
Corporation; First Interstate Bancorp; First of America Bank
Corp.; First Union Corporation; Fleet Financial Group; KeyCorp;
Mellon Bank Corporation; NBD Bancorp, Inc.; National City
Corporation; NationsBank Corporation; Norwest Corporation; and
PNC Bank Corp.  This analysis indicated that Banc One Common
Stock sold at a price of 1.87 times the December 31, 1993 book
value and the comparables sold at an average price of 1.56 times
book value.  Banc One's Common Stock sold at a multiple of price
to trailing 12 months earnings of 11.2, while the comparable
group average price-to-earnings multiple was 10.0.

The summary of The Chicago Corporation analysis set forth above
is a fair summary thereof but does not purport to be a complete
description of the presentations by The Chicago Corporation to
the Mid States Board of Directors.  The Chicago Corporation
believes that its analysis and the summary set forth above must
be considered as a whole and that selecting portions of analysis,
without considering all factors and analyses, could create an
incomplete view of the process by which a fairness opinion is 
rendered.  In connection with its analyses, The Chicago
Corporation assumed that there would be no material adverse
change in general economic, business, market financial and
regulatory conditions, all of which are beyond the control of
Banc One and Mid States.  The analyses performed by The Chicago
Corporation are not necessarily indicative of actual values of
future results, which may be significantly more or less favorable
than suggested by such analyses.

Fees and Indemnification.  The fees due to The Chicago
Corporation under the Agreement between The Chicago Corporation
and Mid States (the "Chicago Corporation Agreement") were payable
by Mid States as follows: $25,000 at the date of execution of The
Chicago Corporation Agreement and $25,000 upon delivery of verbal
conclusions and $50,000 at the time a written opinion is
delivered for the proxy statement.

In addition to such fees, Mid States has agreed to reimburse The
Chicago Corporation for all reasonable out-of-pocket expenses and
will pay to The Chicago Corporation a fee of $1,500 per day for
preparation and court appearances with regard to the fairness
opinion.  Mid States has also agreed to indemnify The Chicago
Corporation, its officers, directors, agents, employees and
certain controlling persons from and against any losses, claims,
damages and liabilities in connection with or arising out of the
transactions or services referred to in The Chicago Corporation
Agreement.  This indemnification is subject to certain conditions
and procedures set forth in an indemnification agreement between
Mid States and The Chicago Corporation.

                        DELAWARE GENERAL CORPORATION LAW              

Section 262. Appraisal rights.

    (a)  Any stockholder of a corporation of this State who holds shares of 
         stock on the date of the making of a demand pursuant to subsection (d) 
         of this section with respect to such shares, who continuously holds 
         such shares through the effective date of the merger or consolidation, 
         who has otherwise complied with subsection (d) of this section and who 
         has neither voted in favor of the merger or consolidation nor 
         consented thereto in writing pursuant to Section 228 of this title 
         shall be entitled to an appraisal by the Court of Chancery of the fair 
         value of his shares of stock under the circumstances described in sub-
         sections (b) and (c) of this section.  As used in this section, the 
         word "stockholder" means a holder of record of stock in a stock 
         corporation and also a member of record of a nonstock corporation; the 
         words "stock" and "share" mean and include what is ordinarily meant 
         by those  words and also membership or membership interest of a 
         member of a nonstock corporation.

    (b)  Appraisal rights shall be available for the shares of any class or 
         series of stock of a constituent corporation in a merger or 
         consolidation to be effected pursuant to Sections 251, 252, 254, 
         257, 258 or 263 of this title:

         (1)  Provided, however, that no appraisal rights under this section 
              shall be available for the shares of any class or series of stock 
              which, at the record date fixed to determine the stockholders 
              entitled to receive notice of and to vote at the meeting of 
              stockholders to act upon the agreement of merger or 
              consolidation, were either (i) listed on a national securities 
              exchange or designated as a national market system security on an 
              interdealer quotation system by the National Association of 
              Securities Dealers, Inc. or (ii) held of record by more than 
              2,000 stockholders; and further provided that no appraisal rights 
              shall be available for any shares of stock of the constituent 
              corporation surviving a merger if the merger did not require for 
              its approval the vote of the stockholders of the surviving 
              corporation as provided in subsection (f) of Section 261 of 
              this title.

         (2)  Notwithstanding paragraph (1) of this subsection, appraisal 
              rights under this section shall be available for the shares of 
              any class or series of stock of a constituent corporation if the 
              holders thereof are required by the terms of an agreement of 
              merger or consolidation pursuant to Sections 251, 252, 254, 
              257, 258 and 263 of this title to accept for such stock anything 
              except:

              a. Shares of stock of the corporation surviving or resulting from 
                 such merger or consolidation;
              b. Shares of stock of any other corporation which at the 
                 effective date of the merger or consolidation will be either 
                 listed on a national securities exchange or designated as a 
                 national market system security on an interdealer quotation 
                 system by the National Association or Securities Dealers, Inc. 
                 or held of record by more than 2,000 stockholders;
<PAGE>
              c. Cash in lieu of fractional shares of the corporations 
                 described in the foregoing subparagraphs a. and b. of this 
                 paragraph; or
              d. Any combination of the shares of stock and cash in lieu of 
                 fractional shares described in the foregoing subparagraphs a., 
                 b. and c. of this paragraph.

         (3)  In the event all of the stock of a subsidiary Delaware corpora- 
              tion party to a merger effected under Section 253 of this title 
              is not owned by the parent corporation immediately prior to the 
              merger, appraisal rights shall be available for the shares of the 
              subsidiary Delaware corporation.

    (c)  Any corporation may provide in its certificate of incorporation that 
         appraisal rights under this section shall be available for the shares 
         of any class or series of its stock as a result of an amendment to its 
         certificate of incorporation, any merger or consolidation in which the 
         corporation is a constituent corporation or the sale of all or 
         substantially all of the assets of the corporation.  If the 
         certificate of incorporation contains such a provision, the procedures 
         of this section, including those set forth in subsections (d) and (e) 
         of this section, shall apply as nearly as is practicable.

    (d)  Appraisal rights shall be perfected as follows:

         (1)  If a proposed merger or consolidation for which appraisal rights 
              are provided under this section is to be submitted for approval 
              at a meeting of stockholders, the corporation, not less than 20 
              days prior to the meeting, shall notify each of its stockholders 
              who was such on the record date for such meeting with respect to 
              shares for which appraisal rights are available pursuant to 
              subsection (b) or (c) hereof that appraisal rights are available 
              for any or all of the share of the constituent corporations, and 
              shall include in such notice a copy of this section.  Each 
              stockholder electing to demand the appraisal off his shares shall 
              deliver to the corporation, before the taking of the vote on the 
              merger or consolidation, a written demand for appraisal of his 
              shares.  Such demand will be sufficient if it reasonably informs 
              the corporation of the identity of the stockholder and that the 
              stockholder intends thereby to demand the appraisal of his 
              shares.  A proxy or vote against the merger or consolidation 
              shall not constitute such a demand.  A stockholder electing to 
              take such action must do so by a separate written demand as 
              herein provided.  Within 10 days after the effective date of such 
              merger or consolidation, the surviving or resulting corporation 
              shall notify each stockholder of each constituent corporation who 
              has complied with this subsection and has not voted in favor of 
              or consented to the merger or consolidation of the date that the 
              merger or consolidation has become effective; or 

          (2) If the merger or consolidation was approved pursuant to Section 
              228 or 253 of this title, the surviving or resulting corporation, 
              either before the effective date of the merger or consolidation 
              or within 10 days thereafter, shall notify each of the stock-
              holders entitled to appraisal rights of the effective date of the 
              merger or consolidation and that appraisal rights are available 
              for any or all of the shares of the constituent corporation, and 
              shall include in such notice a copy of this section.  The notice 
              shall be sent by certified or registered mail, return receipt 
              requested, addressed to the stockholder at his address as it 
              appears on the records of the corporation.  Any stockholder 
              entitled to appraisal rights may, within 20 days after the date 
              of mailing of the notice, demand in writing from the surviving or 
              resulting corporation the appraisal of his shares.  Such demand 
              will be sufficient if it reasonably informs the corporation of 
              the identify of the stockholder and that the stockholder intends 
              thereby to demand the appraisal of his shares.

    (e)  Within 120 days after the effective date of the merger or 
         consolidation, the surviving or resulting corporation or any 
         stockholder who has complied with subsections (a) and (d) hereof and 
         who is otherwise entitled to appraisal rights, may file a petition in 
         the Court of Chancery demanding a determination of the value of the 
         stock of all such stockholders.  Notwithstanding the foregoing, at any 
         time within 60 days after the effective date of the merger or 
         consolidation, any stockholder shall have the right to withdraw his 
         demand for appraisal and to accept the terms offered upon the merger 
         or consolidation.  Within 120 days after the effective date of the 
         merger or consolidation, any stockholder who ahs complied with the 
         requirements of subsections (a) and (d) hereof, upon written request, 
         shall be entitled to receive from the corporation surviving the merger 
         or resulting from the consolidation a statement setting forth the 
         aggregate number of shares not voted in favor of the merger or 
         consolidation and with respect to which demands for appraisal have 
         been received and the aggregate number of holders of such shares.  
         Such written statement shall be mailed to the stockholder within 10 
         days after his written request for such a statement is received by the 
         surviving or resulting corporation or within 10 days after expiration 
         of the period for delivery of demands for appraisal under subsection 
         (d) hereof, whichever is later.

    (f)  Upon the filing of any such petition by a stockholder, service of a 
         copy thereof shall be made upon the surviving or resulting 
         corporation, which shall within 20 days after such service file in the 
         office of the Register in Chancery in which the petition was filed a 
         fully verified list containing the names and addresses of all 
         stockholders who have demanded payment for their shares and with whom 
         agreements as to the value of their shares have not been reached by 
         the surviving or resulting corporation.  If the petition shall be 
         filed by the surviving or resulting corporation, the petition shall be 
         accompanied by such a duly verified list.  The Register in Chancery, 
         if so ordered by the Court, shall give notice of the time and place 
         fixed for the hearing of such petition by registered, 
         certified mail to the surviving or resulting corporation and to the 
         stockholders shown on the list of the addresses therein stated.  Such 
         notice shall also be given by 1 or more publications at least 1 week 
         before the day of the hearing, in a newspaper of general circulation 
         published in the City of Wilmington, Delaware or such publication as 
         the Court deems advisable.  The forms of the notices by mail and by 
         publication shall be approved by the Court, and the costs thereof 
         shall be borne by the surviving or resulting corporation.

    (g)  At the hearing on such petition, the Court shall determine the 
         stockholders who have complied with this section and who have become 
         entitled to appraisal rights.  The Court may require the stockholders 
         who have demanded an appraisal for their shares and who hold stock 
         represented by certificates to submit their certificates of stock to 
         the  Register in Chancery for notation thereon of the pendency of the 
         appraisal proceedings, and if any stockholder fails to comply with 
         such direction, the Court may dismiss the proceedings as to such 
         stockholder.

    (h)  After determining the stockholders entitled to an appraisal, the Court 
         shall appraise the shares, determining their fair value exclusive of 
         any element of value arising from the accomplishment or expectation of 
         the merger or consolidation, together with a fair rate of interest, if 
         any, to be paid upon the amount determined to be the fair value.  In 
         determining such fair value, the Court shall take into account all 
         relevant factors.  In determining the fair rate of interest, the Court 
         may consider all relevant factors, including the rate of interest 
         which the surviving or resulting corporation would have had to pay to 
         borrow money during the pendency of the proceeding.  Upon application 
         by the surviving or resulting corporation or by any stockholder 
         entitled to participate in the appraisal proceeding, the Court may, in 
         its discretion, permit discovery or other pretrial proceedings and may 
         proceed to trial upon the appraisal prior to the final determination 
         of the stockholder entitled to an appraisal.  Any stockholder whose 
         name appears on the list filed by the surviving or resulting 
         corporation pursuant to subsection (f) of this section and who has 
         submitted his certificates of stock to the Register in Chancery, if 
         such is required, may participate fully in all proceedings until it is 
         finally determined that he is not entitled to appraisal rights under 
         this section.

    (i)  The Court shall direct the payment of the fair value of the shares, 
         together with interest, if any, by the surviving or resulting 
         corporation to the stockholders entitled thereto.  Interest may be 
         simple or compound, as the Court may direct.  Payment shall be so made 
         to each such stockholder, in the case of holders of uncertificated 
         stock forthwith, and the case of holders of shares represented by 
         certificates upon the surrender to the corporation of the certificates 
         representing such stock.  The Court's decree may be enforced as other 
         decrees in the Court of Chancery may be enforced, whether such 
         surviving or resulting corporation be a corporation of this State or 
         of any state.
<PAGE>
    (j)  The costs of the proceeding may be determined by the Court and taxed 
         upon the parties as the Court deems equitable in the circumstances.  
         Upon application of a stockholder, the Court may order all or a 
         portion of the expenses incurred by any stockholder in connection with 
         the appraisal proceeding, including, without limitation, reasonable 
         attorney's fees and the fees and expenses of experts, to be charged 
         pro rata against the value of all the shares entitled to an appraisal.

    (k)  From and after the effective date of the merger or consolidation, no 
         stockholder who has demanded his appraisal right as provided in 
         subsection (d) of this section shall be entitled to vote such stock 
         for any purpose or to receive payment of dividends or other 
         distributions payable to stockholders of record at a date which is 
         prior to the effective date of the merger or consolidation; provided, 
         however, that if no petition for an appraisal shall be filed within 
         the time provided in subsection (e) of this section, or if such 
         stockholder shall deliver to the surviving or resulting corporation a 
         written withdrawal of his demand for an appraisal and an acceptance of 
         the merger or consolidation, either within 60 days after the effective 
         date of the merger or consolidation as provided in subsection (e) of 
         this section or thereafter with the written approval of the 
         corporation, then the right of such stockholder to an appraisal shall 
         cease.  Notwithstanding the foregoing, no appraisal proceeding in the 
         Court of Chancery shall be dismissed as to any stockholder without the 
         approval of the Court, and such approval may be conditioned upon such 
         terms as the Court deems just.

    (l)  The shares of the surviving or resulting corporation to which the 
         shares of such objecting stockholders would have been converted had 
         they assented to the merger or consolidation shall have the status of 
         authorized and unissued shares of the surviving or resulting corpora-
         tion.  (8 Del. C. 1953, Section 262; 56 Del. Laws, c. 50; 56 Del. Laws,
         c. 186, Section 24; 57 Del. Laws, c. 148, Sections 27-29; 59 Del. 
         Laws, c. 106, Section 12; 60 Del. Laws, c. 371, Sections 3-12; 63 Del.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20.  Indemnification of Officers and Directors.

Section 1701.13(E) of the Ohio General Corporation Law sets forth provisions 
which define the extent to which a corporation may indemnify directors, 
officers, and employees.  Those provisions have been adopted by the Registrant 
in Article V of Registrant's Code of Rights.  Article V provides for the 
indemnification or the purchase of insurance for the benefit of the directors, 
officers, employees and agents of the Registrant in the event such persons are 
subject to legal action as a result of actions in their capacities as 
directors, officers, employees or agents of the Registrant.  Registrant has 
entered into indemnification agreements with its directors and executive 
officers that provide for indemnification unless the indemnitee's conduct is 
finally adjudged by a court to be knowingly fraudulent, deliberately dishonest 
or willful misconduct.  Registrant indemnifies other officers, employees or 
agents provided such persons acted in good faith and in a manner which they 
reasonably believed to be in or not opposed to the best interest of the 
Registrant or, with respect to criminal actions, had no reason to believe was 
unlawful.

      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.

(c)   The Registrant hereby undertakes that every prospectus (i) that is filed 
      pursuant to paragraph (a) above, 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 has become effective, and that for the purpose of 
      determining liabilities under the Act, each such post-effective amendment 
      shall be deemed to be a new 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.

(d)   Insofar as indemnification for liabilities arising under the Securities 
      Act of 1933 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.

(e)   The undersigned Registrant hereby undertakes to respond to requests for 
      information that is incorporated by reference into the 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 documents filed subsequent to the effective date 
      of the registration statement through the date of responding to the 
      request.

(f)   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 the registration statement when it became effective.

(g)   The undersigned Registrant hereby undertakes:

      (1)  To file, during any period in which offers or sales are being made, 
           a post-effective amendment to this registration statement:

           (i)   To include any prospectus required by Section 10(a)(3) of the 
                 Securities Act of 1933;

           (ii)  To reflect in the prospectus any facts or events arising after 
                 the effective date of the registration statement (or the most 
                 recent post-effective amendment thereof) which, individually 
                 or in the aggregate, represent a fundamental change in the 
                 information set forth in the registration statement;

           (iii) To include any material information with respect to the plan 
                 of distribution not previously disclosed in the registration 
                 statement or any material change to such information in the 
                 registration statement:

      (2)  That, for the purpose of determining any liability under the 
           Securities Act of 1933, each such post-effective amendment shall be 
           deemed to be a new 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.

      (3)  To remove from registration by means of a post-effective amendment 
           any of the securities being registered which remain unsold at the 
           termination of the offering.

                                   SIGNATURES


Pursuant to the requirements of the Securities Act, the Registrant has duly 
caused this Post Effective Amendment No. 1 to the Registration Statement to be 
signed on its behalf by the undersigned, thereunto duly authorized, in the City 
of Columbus, State of Ohio, on April 21, 1994.

                                  WITNESSETH:

MID STATES is a corporation duly organized under the laws of the State of 
Delaware.  Its principal office is located at 506 15th Street, Moline, Rock

capital stock consisting of 750,000 shares of common stock with par value of 
$5.00 per share ("MID STATES Common"), 311,560 of which shares were issued and 
outstanding and 3,040 of which were shares of treasury stock owned by MID 
STATES.  Except as set forth in Exhibit A hereto, MID STATES owns, beneficially 
and of record, all of the issued and outstanding capital stock of the bank 
listed in Exhibit A hereto (the "Bank") and of the corporations listed in 
Exhibit A hereto (the "Companies").  The Bank and the Companies are hereinafter 
referred to collectively as the "Subsidiaries" and each, sometimes, as a 
"Subsidiary."

BANC ONE ILLINOIS is a corporation duly organized under the laws of the State 
of Illinois.  Its principal office is located at One East Old State Capitol 
Plaza, Springfield, Sangamon County, Illinois.  As of March 31, 1993, BANC ONE

and total consolidated assets of $3,025,537,402.  BANC ONE ILLINOIS is a wholly

Its principal office is located at 100 East Broad Street, Columbus, Franklin

The respective Boards of Directors of MID STATES, BANC ONE ILLINOIS and BANC

transactions hereby and have approved the execution and delivery of this Merger 
Agreement.  This Merger Agreement provides for the merger of MID STATES with 
and into BANC ONE ILLINOIS upon the terms and conditions of this Merger 
Agreement (the "Merger").  BANC ONE ILLINOIS will be the surviving corporation 
of the Merger.  From and after the Effective Time, as defined in Section 4 of 
this Merger Agreement, and as and when required by this Merger Agreement, BANC 
ONE will issue shares of BANC ONE Common in exchange for all of the issued and 
outstanding shares of MID STATES Common (excluding any shares held by MID 
STATES as treasury shares).  It is understood by each of the parties hereto 
that BANC ONE seeks, as a result of the Merger, to acquire MID STATES, the Bank 
and the Companies and all of their respective operating assets and 
liabilities.  Subject to the terms and conditions of this Merger Agreement, all 
parties will exert their reasonable best efforts to obtain such regulatory 
approvals and to effect such other actions as are necessary or appropriate to 
consummate the Merger.  Except as may be required upon application of Section 
7(e) of this Merger Agreement, BANC ONE will issue not more than 616,888 shares 
of BANC ONE Common in connection with the transactions contemplated by this 
Merger Agreement.

In consideration of the premises, MID STATES, BANC ONE and BANC ONE ILLINOIS 
hereby make this Merger Agreement and prescribe the terms and conditions of the 
Merger and the mode of carrying the Merger into effect as follows:

 1. Merger.  Subject to the terms and conditions hereinafter set forth, MID 
    STATES shall be merged with and into BANC ONE ILLINOIS pursuant to and in 
    accordance with applicable provisions of the Illinois Business Corporation 
    Act of 1983, as amended (the "Illinois BCA") and the General Corporation 
    Law of the State of Delaware (the "Delaware GCL").

 2. Name.  The name of the surviving corporation (hereinafter called the 
    "Surviving Corporation" whenever reference is made to it as of the 
    Effective Time or thereafter) shall be "BANC ONE ILLINOIS CORPORATION."

 3. Business.  The business of BANC ONE ILLINOIS as the Surviving Corporation 
    shall be that of a bank holding company.  The Surviving Corporation shall 
    exist by virtue of, and be governed by the laws of the State of Illinois 
    and shall have its principal office at One East Old State Capitol Plaza, 
    Springfield, Illinois.

4.  Effective Time of Merger; Articles of Incorporation.  The Merger shall 
    become effective upon the later to occur of (a) issuance by the Secretary 
    of State of the State of Illinois of a certificate of merger with respect 
    thereto as provided in applicable provisions of the Illinois BCA and (b) 
    the filing of a certificate of merger with the Secretary of State of the 
    State of Delaware (the "Effective Time").

    Attached to this Merger Agreement as Exhibit B is a Plan of Merger (the 
    "Plan of Merger") containing certain of the terms of this Merger Agreement, 
    which shall be set forth in substantially the form of such Exhibit B (as 
    the "plan of merger" with respect to the Merger referred to in Section 
    11.25 and the other applicable provisions of the Illinois BCA) in the 
    Articles of Merger filed by MID STATES and BANC ONE ILLINOIS with the 
    Secretary of State of the State of Illinois in order to make the Merger 
    effective.

    The Articles of Incorporation of BANC ONE ILLINOIS in effect as of the 
    Effective Time shall be the Articles of Incorporation of the Surviving 
    Corporation, and the By-Laws of BANC ONE ILLINOIS in effect as of the 
    Effective Time shall be the By-Laws of the Surviving Corporation.

 5. Effect of Merger.  At the Effective Time, the separate corporate existence 
    of MID STATES and BANC ONE ILLINOIS, respectively, shall, as provided in 
    applicable provisions of the Illinois BCA and the Delaware GCL, be merged 
    into and continued in BANC ONE ILLINOIS as the Surviving Corporation, which 
    shall be deemed to be the same corporation as MID STATES and BANC ONE 
    ILLINOIS.  All rights, franchises and interests of MID STATES and BANC ONE 
    ILLINOIS, respectively, in and to every type of property, real, personal 
    and mixed, and choses in action, shall be transferred to and vested in BANC 
    ONE ILLINOIS as the Surviving Corporation by virtue of the Merger without 
    any deed or other transfer in the same manner and to the same extent as 
    such rights, franchises and interests were held or enjoyed by MID STATES 
    and BANC ONE ILLINOIS, respectively, at the Effective Time, as provided in 
    applicable provisions of the Illinois BCA and Delaware GCL.

 6. Liabilities upon Merger; Service of Process.  The Surviving Corporation 
    shall be responsible for all of the liabilities of every kind and 
    description of MID STATES and BANC ONE ILLINOIS existing as of the 
    Effective Time, including, but not limited to, employment agreements and 
    severance agreements, except as may be specifically provided otherwise in 
    this Merger Agreement.

    The filing with the Delaware Secretary of State of an appropriate 
    certificate of merger or other appropriate document as required by the 
    Delaware GCL shall operate as a consent by the Surviving Corporation that 
    it may be sued and served with process in the State of Delaware in any 
    suit, action or proceeding for the enforcement of any obligation or 
    liability of MID STATES or BANC ONE ILLINOIS including any amount payable 
    to any dissenting shareholder; as the consent by the Surviving Corporation 
    to service upon and by the Secretary of State of the State of Delaware as 
    agent of the Surviving Corporation to accept service of process in any such 
    suit, action or proceeding for the enforcement of any such obligation or 
    liability; and as an appointment by the Surviving Corporation of Willard 
    Bunn III, whose address is One East Old State Capitol Plaza, Springfield, 
    Illinois  62701 as agent of the Surviving Corporation for service of 
    process in any action, suit or proceeding to enforce any such obligation or 
    liability of MID STATES or BANC ONE ILLINOIS, to whom the Secretary of 
    State of the State of Delaware may mail a copy of any such process served 
    upon the Secretary of State of the State of Delaware.

 7. Conversion of Shares.

    (a)  At the Effective Time:

         (i)   Each of the not more than 311,560 shares of MID STATES Common 
               that shall be issued and outstanding immediately prior to the 
               Effective Time (excluding any shares held by MID STATES as 
               treasury shares) shall thereupon and without further action be 
               converted into 1.98 shares of BANC ONE Common, subject, however, 
               to (A) the anti-dilution provisions of Sections 7(e) of this 
               Merger Agreement and (B) provisions set forth in Section 7(c) 
               herein relative to fractional shares (the "Exchange Rate").

         (ii)  The 100 shares of BANC ONE ILLINOIS Common issued and 
               outstanding immediately prior to the Effective Time shall 
               continue to be issued and outstanding shares of common stock 
               without par value of the Surviving Corporation.

         (iii) All of the shares of MID STATES Common held by MID STATES as 
               treasury shares immediately prior to the Effective Time shall be 
               cancelled and shall not represent capital stock of the Surviving 
               Corporation and shall not be exchanged for shares of BANC ONE 
               Common.

    (b)  At the Effective Time, stock issued by reason of the Merger shall be 
         allocated to the shareholders of record of MID STATES as of the 
         Effective Time with such shares of BANC ONE Common to be equal to the 
         number of shares of MID STATES Common outstanding immediately prior to 
         the Effective Time multiplied by the Exchange Rate as calculated 
         pursuant to Section 7(a).  Such allocation of BANC ONE Common for each 
         share of MID STATES Common held of record at the Effective Time made 
         on the basis of the Exchange Rate is subject to limitations relative 
         to fractional shares as set forth in Section 7(c) herein and to 
         adjustments pursuant to the anti-dilution provisions of Section 7(e).

    (c)  No certificate for fractional shares of BANC ONE Common will be issued 
         by BANC ONE in connection with the exchange contemplated by the 
         Merger, but in lieu thereof, any holder of MID STATES Common shall, 
         upon surrender of the certificate or certificates representing such 
         MID STATES Common, be paid cash, without interest, by BANC ONE for 
         such fractional shares on the basis of the BANC ONE Average Price (as 
         hereinafter defined).  The BANC ONE Average Price shall mean the 
         average of the closing prices of BANC ONE Common on the New York Stock 
         Exchange ("NYSE") during the Valuation Period (as hereinafter defined) 
         in The Wall Street Journal for NYSE Composite Transactions.  The term 
         "Valuation Period" shall mean the ten consecutive NYSE trading days 
         ending on the sixth NYSE trading day immediately prior to the proposed 
         Effective Time, as designated by BANC ONE pursuant to Section 10(c) of 
         this Merger Agreement.

    (d)  At the Effective Time, holders of certificates formerly representing 
         shares of MID STATES will tender such certificates to BANC ONE and 
         subject to the provisions set forth above relating to fractional 
         shares, BANC ONE, or BANK ONE, INDIANAPOLIS, N.A., as Exchange Agent 
         for BANC ONE, will distribute to the holders of certificates formerly 
         representing shares of MID STATES Common in exchange for and upon 
         surrender for cancellation by such holders of a certificate or 
         certificates formerly representing shares of MID STATES Common the 
         certificate(s) for shares of BANC ONE Common in accordance with the 
         Exchange Rate.  Each certificate formerly representing MID STATES 
         Common (other than certificates representing shares of MID STATES 
         Common subject to the rights of dissenting shareholders) shall be 
         deemed for all purposes to evidence the ownership of the number of 
         shares of BANC ONE Common and cash for fractional shares into which 
         such shares have been converted, except, however, and notwithstanding 
         the foregoing, that, until such surrender of the certificate or 
         certificates formerly representing shares of MID STATES Common, the 
         holder thereof shall not be entitled to receive any dividend or other 
         payment or distribution payable to holders of BANC ONE Common.  Upon 
         such surrender (or in lieu of surrender other provisions reasonably 
         satisfactory to BANC ONE as are made as set forth in the next 
         following paragraph), there shall be paid to the person entitled 
         thereto the aggregate amount of dividends or other payments or 
         distributions (in each case without interest) which became payable 
         after the Effective Time on the whole shares of BANC ONE Common 
         represented by the certificates issued upon such surrender and 
         exchange or in accordance with such other provisions, as the case may 
         be.  After the Effective Time, the holders of certificates formerly 
         representing shares of MID STATES Common shall cease to have rights 
         with respect to such shares (except such rights, if any, as they may 
         have as dissenting shareholders), and except as aforesaid, their sole 
         rights shall be to exchange said certificates for shares of BANC ONE 
         Common and cash for fractional shares in accordance with this Merger 
         Agreement.

         Certificates representing shares of MID STATES Common surrendered for 
         cancellation by each shareholder entitled to exchange shares of MID 
         STATES Common for shares of BANC ONE Common by reason of the Merger 
         shall be appropriately endorsed or accompanied by such appropriate 
         instruments of transfer as BANC ONE may reasonably require; provided, 
         however, that if there be delivered to BANC ONE by any person who is 
         unable to produce any such certificate formerly representing shares of 
         MID STATES Common for transfer (i) evidence to the reasonable 
         satisfaction of BANC ONE that any such certificate has been lost, 
         wrongfully taken or destroyed, (ii) such security or indemnity as 
         reasonably may be requested by BANC ONE to save it harmless, and (iii) 
         evidence to the reasonable satisfaction of BANC ONE that such person 
         is the owner of the shares theretofore represented by each certificate 
         claimed by him or her to be lost, wrongfully taken or destroyed and 
         that he or she is the person who would be entitled to present each 
         such certificate and to receive shares of BANC ONE Common pursuant to 
         this Merger Agreement, then BANC ONE, in the absence of actual notice 
         to it that any shares theretofore represented by any such certificate 
         have been acquired by a bona fide purchaser, shall deliver to such 
         person the certificate(s) representing shares of BANC ONE Common which 
         such person would have been entitled to receive upon surrender of each 
         such lost, wrongfully taken or destroyed certificate of MID STATES 
         Common.

    (e)  If prior to the Effective Time BANC ONE or MID STATES shall (i) 
         declare a stock dividend upon or subdivide, split up, reclassify or 
         combine its shares of common stock; or (ii) declare a dividend or make 
         a distribution on its common stock in any security convertible into 
         its common stock, appropriate adjustment or adjustments will be made 
         in the Exchange Rate.

 8. Board of Directors; Employees; and Name Changes.  The directors of BANC ONE 
    ILLINOIS immediately prior to the Effective Time, together with MID STATES 
    director Thomas H. Robinson, shall serve as the directors of the Surviving 
    Corporation immediately following the Effective Time and until the next 
    annual meeting of shareholders at which their respective successors are 
    elected and qualified.  The officers and employees of the Surviving 
    Corporation immediately following the Effective Time shall be the officers 
    and employees of BANC ONE ILLINOIS immediately before the Effective Time 
    with each such person to hold the same office in the Surviving Corporation 
    as held by such person in BANC ONE ILLINOIS.  The directors, officers and 
    employees of the Subsidiaries immediately following the Effective Time 
    shall be the directors, officers and employees of the respective 
    Subsidiaries immediately before the Effective Time.

    MID STATES will cooperate with BANC ONE in the procurement of requisite 
    corporate and regulatory approvals and will use its reasonable best efforts 
    to take such other steps as are appropriate and necessary to effect changes 
    in the name of each of the Subsidiaries to include the words "BANK ONE" or 
    "BANC ONE" so that such name changes will become effective at the Effective 
    Time.

9.  Stock Options and Employee Benefits.

    (a)  As of the date of the Merger Agreement, there are no outstanding and 
         unexercised stock options for shares of MID STATES Common.

    (b)  All employee benefit programs of MID STATES and the Subsidiaries will 
         be terminated, grandfathered or merged in BANC ONE benefit plans and 
         programs will be made available and applicable to the employees of MID 
         STATES and the Subsidiaries following the Effective Time and shall be 
         as described in and governed by a Benefits Letter Agreement dated May 
         24, 1993, pertaining to benefits between MID STATES and BANC ONE (the 
         "Benefits Agreement") or in the Second Benefits Letter Agreement dated 
         May 24, 1993 pertaining to employee issues between MID STATES and BANC 
         ONE (the "Second Benefits Agreement").

10. Undertakings of the Parties.  MID STATES, BANC ONE ILLINOIS and BANC ONE 
    further agree as follows:

    (a)  This Merger Agreement and the Plan of Merger shall be submitted to the 
         shareholders of MID STATES for approval at a meeting to be called and 
         held in accordance with applicable law and the Certificate of 
         Incorporation and By-Laws of MID STATES.  Such shareholders' meeting 
         will be scheduled to be held approximately 30 days following the 
         mailing by MID STATES of its proxy statement to its shareholders 
         promptly following the effective date of the registration statement to 
         be filed by BANC ONE with the Securities and Exchange Commission (the 
         "SEC") as provided in Section 10(d).  MID STATES and BANC ONE will 
         cooperate with each other in order to facilitate the preparation, 
         filing and clearance of the registration statement and the proxy 
         statement under Federal and State securities laws to be used with 
         respect to such shareholders' meeting and the exchange of shares as 
         contemplated by this Merger Agreement.

    (b)  BANC ONE will promptly prepare and file an application (believed in 
         good faith by BANC ONE to be substantially complete in form and 
         substance) to the Board of Governors of the Federal Reserve System 
         (the "Board") under appropriate provisions of Section 3 of the Bank 
         Holding Company Act of 1956, as amended, and an application to the 
         Illinois Commissioner of Banks and Trust Companies (the "Illinois 
         Commissioner") under appropriate provisions of the Illinois Bank 
         Holding Company Act of 1957, as amended, for prior approval of the 
         proposed acquisition of MID STATES and/or the Subsidiaries by BANC ONE 
         and/or BANC ONE ILLINOIS.  MID STATES will furnish BANC ONE such 
         information, appropriate representations and documents as may be 
         reasonably requested by BANC ONE in connection therewith.  BANC ONE 
         will use its reasonable best efforts to cause such applications to be 
         approved by the Board and the Illinois Commissioner, respectively, and 
         to obtain such other regulatory consents and approvals as may be 
         necessary to facilitate the Merger and will provide MID STATES and its 
         counsel with an opportunity to review drafts of all such applications 
         and to comment on the portions of such applications that contain 
         information about MID STATES.  BANC ONE will provide MID STATES and 
         its counsel with copies of the public portions of all such 
         applications as filed, together with correspondence to or from the 
         Board and Illinois Commissioner related thereto.

    (c)  After receipt of the Board's prior approval of BANC ONE's and BANC ONE 
         ILLINOIS' acquisition of MID STATES, after approval of the acquisition 
         by the Illinois Commissioner, and after the approval of the 
         shareholders of MID STATES, as provided in Section 10(a), BANC ONE 
         shall designate the date as of which BANC ONE desires the Merger to 
         become effective and the Effective Time shall occur at the time and on 
         the date so designated, subject to Section 24 of this Merger 
         Agreement.  In no event will the date designated by BANC ONE as the 
         Effective Time be sooner than the day following the day on which all 
         approvals of the Board and the Illinois Commissioner have been 
         received and any required waiting periods with respect thereto have 
         expired, nor will the date designated by BANC ONE as the Effective 
         Time be later than 31 days following the date at which all approvals 
         of the Board and the Illinois Commissioner have been received and any 
         required waiting periods with respect thereto have expired.

    (d)  BANC ONE will prepare and file with the SEC and use its reasonable 
         best efforts to cause to become effective, a registration statement, 
         including the related prospectus and proxy statement referred to in 
         Section 10(a), above ("Proxy Statement"), and any required amendments 
         thereto or supplements to any prospectus contained therein, relating 
         to the exchange of BANC ONE Common contemplated by this Merger 
         Agreement.  Such registration statement will not cover resales by any 
         persons who may be considered "underwriters" under Rule 145(c) of the 
         Securities Act of 1933, as amended (the "1933 Act").  BANC ONE shall 
         use its reasonable best efforts to have the shares of BANC ONE Common 
         qualified or exempted from qualification under all applicable state 
         securities laws as soon as possible.  In the event that a stop order 
         has been issued, or threatened, by the SEC, that suspends or would 
         suspend the effectiveness of the registration statement, BANC ONE 
         shall use its reasonable best efforts to promptly remove, or cause not 
         to be issued, any such stop order.

    (e)  BANC ONE and/or BANC ONE ILLINOIS will assume and pay all expenses 
         incident to the obtaining of the requisite regulatory consents and 
         approvals.  Without limiting the generality of the foregoing, the 
         expenses to be assumed and paid by BANC ONE shall include (i) all 
         legal and other expenses and taxes incurred by BANC ONE incident to 
         the consummation of the Merger contemplated by this Merger Agreement, 
         (ii) all legal and other expenses incurred by BANC ONE incident to the 
         preparation and filing of the applications to the Board, the Illinois 
         Commissioner, and other requests for regulatory consents and approvals 
         with the appropriate bank regulatory agencies as set forth in or 
         contemplated by this Merger Agreement, and (iii) all legal and other 
         expenses, if any, incurred in connection with the registration of BANC 
         ONE Common under the Federal and State securities laws.  The expenses 
         to be assumed and paid by BANC ONE and/or BANC ONE ILLINOIS shall not 
         include any legal or other expenses incurred by MID STATES in the 
         negotiation of the Merger, the examination or review of documents for 
         its own benefit, in connection with its own corporate proceedings or 
         to any investment banker or advisor for services rendered on its 
         behalf.  BANC ONE will pay the expenses of reproducing the Proxy 
         Statement.  MID STATES shall be responsible for its legal and 
         accounting fees associated with the Proxy Statement, including the 
         expenses and fees to Donaldson, Lufkin and Jenrette Securities 
         Corporation ("DLJ") with respect to any opinion expressed with respect 
         to the fairness of the Merger from a financial point of view and/or 
         the Exchange Rate to the holders of MID STATES Common (the "DLJ 
         Fairness Opinion").  Any fees and expenses assumed and paid by BANC 
         ONE and/or BANC ONE ILLINOIS pursuant to this Section 10(e), whether 
         directly or indirectly incurred, shall not reduce or otherwise effect 
         the Exchange Rate.

    (f)  All information furnished by one party to another party in connection 
         with this Merger Agreement (whether before or after the date of this 
         Merger Agreement) and the transactions contemplated hereby which is 
         regarded by such furnishing party as confidential (and is so 
         designated not later than the time of delivery or the date of this 
         Merger Agreement) will be kept confidential by such other party and 
         will be used only in connection with this Merger Agreement and the 
         transactions contemplated hereby, except to the extent that such 
         information (i) is already known to such other party when received, 
         (ii) thereafter becomes lawfully obtainable from other sources, 
         otherwise than in violation of this paragraph or similar duties or 
         provisions regarding confidentiality, or (iii) is, in the reasonable 
         opinion of legal counsel for BANC ONE, required to be disclosed in any 
         document filed with the SEC, the Board, the Illinois Commissioner or 
         any other governmental agency or authority.  The provisions of this 
         Merger Agreement supersede and shall serve to terminate any 
         Confidentiality Agreement between the parties.

    (g)  BANC ONE will provide MID STATES and its counsel with copies of all 
         filings made by BANC ONE with the SEC under the Securities Exchange 
         Act of 1934, as amended, (the "1934 Act") and the 1933 Act and the 
         respective rules and regulations of said Commission thereunder at the 
         time such filings are made at any time prior to the Effective Time.

    (h)  BANC ONE and BANC ONE ILLINOIS will furnish to MID STATES all 
         information concerning BANC ONE and BANC ONE ILLINOIS reasonably 
         required by MID STATES in connection with the preparation of proxy 
         solicitation materials for use in soliciting proxies in connection 
         with the meeting of MID STATES' shareholders called for the purpose of 
         voting on the Merger and will promptly advise MID STATES if BANC ONE 
         determines that any of such information is or becomes false or 
         misleading in any material respect.  MID STATES will furnish to BANC 
         ONE all information concerning MID STATES and the Subsidiaries 
         reasonably required by BANC ONE in connection with BANC ONE's 
         preparation of the registration statement (including the related 
         prospectus) and any required amendments or supplements thereto, or in 
         connection with other filings by BANC ONE relating to the registration 
         of its shares and will promptly advise BANC ONE if MID STATES 
         determines that any such information is or becomes false or misleading 
         in any material respect.

    (i)  No press release or other public disclosure of matters related to this 
         Merger Agreement or any of the transactions contemplated hereby shall 
         be made by MID STATES or BANC ONE unless the other party shall have 
         provided its prior consent to the form and substance thereof; 
         provided, however, that nothing herein shall be deemed to prohibit any 
         party hereto from making any disclosure which its counsel deems 
         necessary or advisable in order to fulfill such party's disclosure 
         obligations imposed by law.

    (j)  Prior to the Effective Time, BANC ONE will vote all the shares of BANC 
         ONE ILLINOIS to approve and adopt the proposal to merge BANC ONE 
         ILLINOIS and MID STATES at a meeting of the shareholders of BANC ONE 
         ILLINOIS held for such purpose or by means of a unanimous written 
         consent of BANC ONE ILLINOIS shareholders adopted in lieu of a meeting 
         to approve the Merger and approve this Merger Agreement.

    (k)  For not less than the two-year period immediately following the 
         Effective Time, BANC ONE shall make available adequate current public 
         information about itself as that terminology is used in and as 
         required by Rule 144(c) of the SEC under the 1933 Act.

    (l)  Each of BANC ONE, BANC ONE ILLINOIS and MID STATES will use its 
         reasonable best efforts to cause the Merger to qualify for 
         pooling-of-interests accounting treatment.

    (m)  MID STATES will use its reasonable best efforts to cause each person 
         who, in the joint opinion of counsel for BANC ONE and MID STATES is at 
         the Effective Time or was, at the time of MID STATES' shareholders' 
         meeting referred to in Section 10(a) hereof, an "affiliate" of MID 
         STATES (as that term is used in Rules 144 and 145 promulgated by the 
         SEC under the 1933 Act), to execute and deliver to BANC ONE the 
         written undertakings in the form attached hereto as Exhibit C.

    (n)  BANC ONE will initiate a pre-acquisition investigation and review of 
         the books, records and facilities of MID STATES and its Subsidiaries 
         and will complete such pre-acquisition investigation not later than 60 
         days following the date of this Merger Agreement.  BANC ONE shall 
         advise MID STATES at the conclusion of such pre-acquisition 
         investigation of all matters then known to BANC ONE which BANC ONE 
         shall in good faith determine to be either (i) inconsistent in any 
         material and adverse respect with any of the representations and 
         warranties of MID STATES contained in this Merger Agreement or (ii), 
         in the reasonable judgment of the Board of Directors of BANC ONE, to 
         be either (x) of such significance as to materially and adversely 
         affect the financial condition or the results of operations of MID 
         STATES and the Subsidiaries on a consolidated basis or (y) to deviate 
         materially and adversely from MID STATES' audited financial statements 
         for the year ended December 31, 1992.  BANC ONE shall have the right 
         to terminate this Merger Agreement as set forth in Section 24(c) and 
         supplemented by the MID STATES Disclosure Letter (as hereinafter 
         defined).

    (o)  MID STATES will initiate a pre-acquisition investigation and review of 
         the books, records and facilities of BANC ONE and its subsidiaries and 
         will complete such pre-acquisition investigation not later than 10 
         business days following the date of this Merger Agreement. MID STATES 
         shall advise BANC ONE at the conclusion of such pre-acquisition 
         investigation of all matters then known to MID STATES which MID STATES 
         shall in good faith determine to be either (i) inconsistent in any 
         material and adverse respect with any of the representations and 
         warranties of BANC ONE contained in this Merger Agreement or (ii) in 
         the reasonable judgment of the Board of Directors of MID STATES, to be 
         either (x) of such significance as to materially and adversely affect 
         the financial condition or the results of operations of BANC ONE and 
         its subsidiaries on a consolidated basis or (y) to deviate materially 
         and adversely from BANC ONE's audited financial statements for the 
         year ended December 31, 1992.  MID STATES shall have the right to 
         terminate this Merger Agreement as set forth in Section 24(d) and 
         supplemented by the BANC ONE Disclosure Letter (as hereinafter 
         defined).

    (p)  In addition to BANC ONE's pre-acquisition investigation of MID STATES 
         and its Subsidiaries and MID STATES' pre-acquisition investigation of 
         BANC ONE and its subsidiaries, BANC ONE and MID STATES shall each 
         provide the other with adequate opportunity to conduct such further 
         reviews and examinations of the business, properties and conditions 
         (financial and otherwise) of the other as BANC ONE and MID STATES, 
         respectively, shall deem prudent, provided that such investigations 
         shall not interfere unreasonably with the normal operations of the 
         party being reviewed.

    (q)  BANC ONE will use its reasonable best efforts to cause the shares of 
         BANC ONE Common to be issued to the shareholders of MID STATES 
         pursuant to this Merger Agreement to be listed on the NYSE as of the 
         Effective Time.

11. Dissenting Shareholders.  Shareholders of MID STATES Common who do not vote 
    their shares in favor of the Merger and otherwise perfect applicable 
    dissenters' rights will be entitled to dissenters or appraisal rights 
    pursuant to applicable provisions of the Delaware GCL.

12. Tax Opinion.  BANC ONE and MID STATES shall use their respective reasonable 
    best efforts to obtain from Vedder, Price, Kaufman & Kammholz and cause to 
    be included in the registration statement a written opinion addressed to, 
    among others, MID STATES, its shareholders and BANC ONE, that, based upon 
    the Internal Revenue Code of 1986, as amended (the "Code"), the regulations 
    thereunder, and rulings issued by the Internal Revenue Service in 
    transactions similar to those contemplated by this Merger Agreement, for 
    Federal income tax purposes:

    (a)  The merger of MID STATES into BANC ONE ILLINOIS, pursuant to this 
         Agreement, will constitute a reorganization within the meaning of 
         Section 368(a)(1)(A) and Section 368(a)(2)(D) of the Code.  MID 
         STATES, BANC ONE ILLINOIS and BANC ONE will each be considered "a 
         party to a reorganization" within the meaning of Section 368(b) of the 
         Code for purposes of this reorganization.

    (b)  No gain or loss will be recognized by MID STATES upon the transfer of 
         the assets and liabilities to BANC ONE ILLINOIS in exchange for the 
         shareholders of MID STATES receiving BANC ONE Common;

    (c)  No gain or loss will be recognized by BANC ONE ILLINOIS upon the 
         receipt of the assets and liabilities of MID STATES in exchange for 
         the shareholders of MID STATES receiving BANC ONE Common;

    (d)  The tax basis of the assets of MID STATES in the hands of BANC ONE 
         ILLINOIS will be the same as the tax basis of such assets in the hands 
         of MID STATES immediately prior to the transfer;

    (e)  The holding period of the assets of MID STATES transferred to BANC ONE 
         ILLINOIS will include the period during which such assets were held by

    (f)  No gain or loss will be recognized by the shareholders of MID STATES 
         upon the receipt of BANC ONE Common in exchange for their shares of

         exercise of dissenters' rights or in lieu of the receipt of fractional 
         shares);

    (g)  The tax basis of the BANC ONE Common (including any fractional share 
         interests to which they may be entitled) received by the shareholders 
         of MID STATES will be the same as the tax basis of the MID STATES 
         shares exchanged therefor; and

    (h)  The holding period of the BANC ONE Common received by the shareholders 
         of MID STATES will include the holding period of the MID STATES shares 
         exchanged therefor, provided that at the time of the exchange the MID

13. Representations and Warranties of BANC ONE.  BANC ONE represents and 
    warrants to MID STATES that, except as set forth in BANC ONE's disclosure 
    letter to MID STATES dated May 24, 1993 and delivered to MID STATES not 
    later than the time of the execution of this Merger Agreement (the "BANC 
    ONE Disclosure Letter"), and except as otherwise indicated below:

    (a)  BANC ONE is a corporation duly organized and validly existing in good 
         standing under the laws of the State of Ohio, is a registered bank 
         holding company under the Bank Holding Company Act of 1956, as 
         amended, and is qualified to do business and is in good standing in 
         the State of Ohio, together with all other jurisdictions where it is 
         both required to so qualify and where the failure to so qualify would 
         have a material adverse effect on the business, operations, financial 
         condition or results of operations of such party and its subsidiaries, 
         taken as a whole, or on the ability of such party to consummate the 
         transactions contemplated hereby, and BANC ONE has full power and 
         authority (including all licenses, franchises, permits and other 
         governmental authorizations which are legally required) to engage in 
         the businesses and activities now conducted by it and its 
         subsidiaries.  BANC ONE is not subject to any formal or informal 
         agreement or understanding with, nor is it subject to any order of, 
         any bank regulatory authority restricting or prohibiting or attempting 
         to restrict or prohibit any activities or conduct of BANC ONE.  As of 
         March 31, 1993, the authorized capital stock of BANC ONE consisted of 
         (i) 600,000,000 shares of BANC ONE Common Stock without par value, of 
         which a total of 258,798,094 shares were issued and outstanding and 
         none of which were shares held by BANC ONE as treasury stock and (ii) 
         35,000,000 shares of preferred stock without par value, of which 
         287,536 shares were issued and outstanding as Class B Convertible, no 
         par value shares, and 5,000,000 shares were issued and outstanding as 
         Series C $3.50 Cumulative Convertible Preferred Stock.  All of the 
         issued and outstanding shares of BANC ONE's capital stock are duly 
         authorized, validly issued, fully paid, nonassessable and subject to 
         no pre-emptive rights.  Subject only to obtaining the required 
         regulatory approvals, BANC ONE is, and at all times after the date of 
         this Merger Agreement to and including the Effective Time will be, 
         authorized to effect the Merger under applicable law.

    (b)  BANC ONE has furnished to MID STATES copies of the following financial 
         statements relating to BANC ONE and its consolidated subsidiaries:  
         (i) the audited Consolidated Balance Sheets of BANC ONE as of December 
         31, 1992 and 1991 and the Consolidated Statements of Income, 
         Shareholders' Equity and Cash Flows for the years then ended, together 
         with the notes thereto, as audited by Coopers & Lybrand, independent 
         auditors together with the notes thereto; and (ii) the unaudited 
         Consolidated Balance Sheet of BANC ONE as at March 31, 1993 and the 
         unaudited Consolidated Statements of Income and Shareholders' Equity 
         for the period then ended, together with the notes thereto.  Each of 
         the aforementioned financial statements present fairly, in accordance 
         with generally accepted accounting principles (applied on a consistent 
         basis except as disclosed in the footnotes thereto), the consolidated 
         financial position and results of operations of BANC ONE as of the 
         dates and for the periods therein set forth.  Such financial 
         statements do not, as of the dates thereof, include any material asset 
         or omit any material liability, absolute or contingent, or other fact, 
         the inclusion or omission of which renders such financial statements, 
         in light of the circumstances under which they were made, misleading 
         in any material respect.  Since March 31, 1993, there has not been any 
         change in the financial condition, results of operations or business 
         of BANC ONE and its subsidiaries that has had a material adverse 
         effect on the financial condition or results of operations of such 
         party and its subsidiaries, taken as a whole, or on the ability of 
         such party to consummate the transaction contemplated hereby (a 
         "Material Adverse Effect").  Since March 31, 1993, BANC ONE has issued 
         approximately 13,378,000 additional shares of BANC ONE Common.

    (c)  The Boards of Directors of BANC ONE and BANC ONE ILLINOIS have duly 
         authorized the execution and delivery of this Merger Agreement and 
         approved the Merger as contemplated by said Merger Agreement.  No 
         authorization of this Merger Agreement or of the transactions hereby 
         contemplated is required by the shareholders of BANC ONE.  BANC ONE 
         and BANC ONE ILLINOIS have all requisite power and authority to enter 
         into this Merger Agreement and, after its vote of the shares of BANC 
         ONE ILLINOIS in favor of the Merger as contemplated by Section 10(j), 
         BANC ONE and BANC ONE ILLINOIS will have the authority to consummate 
         the transactions contemplated hereby.  This Merger Agreement 
         constitutes the valid and legally binding and enforceable obligation 
         of each of BANC ONE and BANC ONE ILLINOIS and this Merger Agreement 
         and the consummation of the Merger have been duly authorized and 
         approved on behalf of BANC ONE and BANC ONE ILLINOIS by all requisite 
         corporate action.  Provided the required approvals are obtained from 
         the Board and the Illinois Commissioner, neither the execution and 
         delivery of this Merger Agreement nor the consummation of the Merger 
         will conflict with, result in the breach of, constitute a default 
         under or accelerate the performance provided by the terms of any law, 
         or any rule or regulation of any governmental agency or authority or 
         any judgment, order or decree of any court, bank regulatory agency or 
         other governmental agency to which BANC ONE or BANC ONE ILLINOIS is 
         subject, any contract, agreement or instrument to which BANC ONE or 
         BANC ONE ILLINOIS is a party or by which BANC ONE or BANC ONE ILLINOIS 
         is bound or committed, or the Articles of Incorporation or Regulations 
         of BANC ONE or the Articles of Incorporation or By-Laws of BANC ONE 
         ILLINOIS, or constitute an event which with the lapse of time or 
         action by a third party, could, to the best of BANC ONE's knowledge, 
         result in the default under any of the foregoing or result in the 
         creation of any lien, charge or encumbrance upon any of the assets or 
         properties of BANC ONE or BANC ONE ILLINOIS or upon any of the stock 
         of BANC ONE or BANC ONE ILLINOIS or adversely affect the ability of 
         BANC ONE to consummate the transactions contemplated hereby, except, 
         in the case of contracts, agreements or instruments, such defaults, 
         conflicts or breaches which either (i) will be cured or waived prior 
         to the Effective Time or (ii) if not so cured or waived would not, in 
         the aggregate, have a Material Adverse Effect.

    (d)  The reserve for possible loan and lease losses shown on the March 31, 
         1993 Consolidated Balance Sheet of BANC ONE and its subsidiaries  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, without limitation, accrued interest 
         receivable) as of March 31, 1993.

    (e)  Except as disclosed in the financial statements referred to in Section 
         13(b), there is no litigation, action, suit, investigation or 
         proceeding pending or, to the best of the knowledge after due inquiry 
         of BANC ONE and its executive officers, overtly threatened, against or 
         affecting BANC ONE or any of its subsidiaries or involving any of 
         their respective properties or assets, at law or in equity, before any 
         federal, state, municipal, local or other governmental authority, 
         which is reasonably likely to be resolved adversely to the interest of 
         BANC ONE or its subsidiaries and, if so resolved, would have a 
         Material Adverse Effect or materially impair its ability, or that of 
         BANC ONE ILLINOIS, to perform under this Merger Agreement, and to the 
         best of the knowledge and belief after due inquiry of BANC ONE and its 
         executive officers, no one has reasonable or valid grounds on which it 
         reasonably can be expected that anyone will assert or initiate any 
         such litigation, action, suit, investigation or proceeding against 
         BANC ONE or any of its subsidiaries based upon the wrongful action or 
         inaction of BANC ONE or any of its subsidiaries or any of their 
         respective officers, directors or employees.

    (f)  At the Effective Time and on such subsequent dates when the former 
         shareholders of MID STATES surrender their MID STATES share 
         certificates for cancellation, the shares of BANC ONE Common to be 
         exchanged with former shareholders of MID STATES will have been duly 
         authorized and validly issued by BANC ONE and will be fully paid and 
         nonassessable and subject to no pre-emptive rights.

    (g)  BANC ONE and each of its subsidiaries have good and marketable title 
         to all their respective assets and properties, whether real or 
         personal, tangible or intangible, including without limitation the 
         capital stock of its subsidiaries and all other assets and properties 
         reflected in BANC ONE's Consolidated Balance Sheet as of March 31, 
         1993 or acquired subsequent thereto (except to the extent that such 
         assets and properties have been disposed of for fair value in the 
         ordinary course of business since March 31, 1993).  Such assets and 
         properties are subject to no liens, mortgages, security interests, 
         encumbrances, pledges or charges of any kind, except (i) as noted in 
         said Consolidated Balance Sheet or the notes thereto; (ii) statutory 
         liens for taxes not yet delinquent; (iii) landlord's liens; and (iv) 
         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 such liens, mortgages, security interests, encumbrances 
         and charges do not, in the aggregate, have a Material Adverse Effect.  
         BANC ONE and its subsidiaries as lessees have the unqualified right 
         under valid and subsisting leases to occupy, use, possess and control 
         all property leased by BANC ONE and its subsidiaries.

    (h)  To the best of the knowledge after due inquiry of BANC ONE and its 
         executive officers, BANC ONE and its subsidiaries have complied with 
         all laws, regulations and orders applicable to them and to the conduct 
         of their businesses, including without limitation, all statutes, rules 
         and regulations pertaining to the conduct of banking activities except 
         for violations which together with any penalty which results therefrom 
         has not had and will not have a Material Adverse Effect.  Neither BANC 
         ONE nor any of its subsidiaries is in default under, and no event has 
         occurred which, to the best of BANC ONE's knowledge, after due 
         inquiry, is likely to result in the default under the terms of any 
         judgment, decree, order, writ, rule or regulation of any governmental 
         authority or court, whether federal, state or local and whether at law 
         or in equity, in each case where the default has had or is likely to 
         have a Material Adverse Effect.

    (i)  BANC ONE and BANC ONE ILLINOIS have not incurred and will not incur 
         directly or indirectly any liability for brokerage, finders', agents' 
         or investment bankers' fees or commissions in connection with this 
         Merger Agreement or the transactions contemplated hereby, except for 
         fees associated with the provision of the DLJ Fairness Opinion, for 
         which BANC ONE and/or BANC ONE ILLINOIS may be obligated by operation 
         of law as a result of the Merger.

    (j)  Each pension, stock bonus or purchase, profit-sharing, retirement, 
         health and welfare plan maintained by or covering employees of BANC 
         ONE or any subsidiary of BANC ONE other than a multiemployer plan (for 
         purposes of this paragraph hereinafter referred to collectively as the 
         "Plans") which purports to be a qualified plan under Section 401(a) of 
         the Code is so qualified.  All of the Plans which constitute employee 
         pension benefit or employee welfare benefit plans subject to the 
         Employee Retirement Income Security Act of 1974, as amended ("ERISA"), 
         have been maintained in compliance in all material respects with the 
         applicable requirements of ERISA.  All material notices, reports and 
         other filings required under applicable law to be given or made to or 
         with any governmental agency with respect to the Plans have been 
         timely filed or delivered.  BANC ONE has no knowledge of any 
         circumstances which would adversely affect the qualification of the 
         Plans or their compliance with the applicable requirements of ERISA, 
         would result or have resulted in liability under Title IV of ERISA or 
         of any "reportable event" (as such term is defined in Section 4043(b) 
         of ERISA) or any "prohibited transaction" (as such term is defined in 
         Section 406 of ERISA and Section 4975(c) of the Code) which has 
         occurred since the date on which said sections became applicable to 
         the Plans and which could reasonably be expected to result in any 
         material liability of BANC ONE or any subsidiary to the Pension 
         Benefit Guaranty Corporation (the "PBGC"), the Department of Treasury, 
         the Department of Labor or any multiemployer plan.  Those Plans which 
         are defined benefit plans within the meaning of ERISA meet the minimum 
         funding standards set forth in the Code and ERISA and the assets of 
         such Plans equal or exceed the present value of accrued benefits on a 
         termination basis under such Plans as of the most recent plan 
         valuation date.  There are no pending or threatened claims (other than 
         claims for benefits in the ordinary course), lawsuits or arbitrations 
         which have been asserted or instituted against the Plans, any 
         fiduciaries thereof with respect to their duties to the Plans or the 
         assets of any of the trusts under any of the Plans which could 
         reasonably be expected to result in any material liability of BANC ONE 
         or any subsidiary to the PBGC, Department of Treasury, Department of 
         Labor or any multiemployer plan.

    (k)  BANC ONE and/or its subsidiaries have duly filed all federal, state, 
         county and local income, franchise, bank, excise, real and personal 
         property and other tax returns and reports (including, but not limited 
         to, those relating to social security, withholding, unemployment 
         insurance, and occupation, sales and use taxes and those filed on a 
         consolidated, combined or unitary basis) required to have been filed 
         by BANC ONE or its subsidiaries up to the date hereof.  All of the 
         foregoing returns are true and correct in all material respects, and 
         BANC ONE and its subsidiaries have paid or, prior to the Effective 
         Time, will pay all taxes, interest, additions to tax, and penalties 
         shown on such returns or reports as being due or (except to the extent 
         the same are contested in good faith and, if material, summarized in 
         the BANC ONE Disclosure Letter) claimed to be due to any federal, 
         state, county, local or other taxing authority, and there is, and at 
         the Effective Time will be, no basis for any additional claim or 
         assessment which might materially and adversely affect BANC ONE and 
         its subsidiaries, except for those being contested in good faith and 
         summarized in the BANC ONE Disclosure Letter.  BANC ONE and its 
         subsidiaries have paid or made adequate provision in their financial 
         statements or on their books and records for all taxes payable in 
         respect of all periods ending on or before the date hereof.  BANC ONE 
         and its subsidiaries have, or at the Effective Time will have, no 
         liability for any taxes, interest, additions to tax, or penalties of 
         any nature whatsoever, except for those taxes which may have arisen up 
         to the Effective Time in the ordinary course of business and are 
         properly accrued on the books of BANC ONE and its subsidiaries as of 
         the Effective Time or are being contested in good faith and have, if 
         material, been summarized in the BANC ONE Disclosure Letter.

    (l)  BANC ONE and its subsidiaries have in effect insurance coverage with 
         reputable insurers, which in respect of amounts, premiums, types and 
         risks insured, constitutes reasonably adequate coverage against all 
         risks customarily insured against by bank holding companies and their 
         subsidiaries comparable in size and operations to BANC ONE and its 
         subsidiaries.

    (m)  Neither the Proxy Statement nor the related registration statement nor 
         any amendment or supplement thereto that is filed with the SEC in 
         connection with the transactions contemplated hereby (except for any 
         information which has been or shall be supplied by MID STATES for 
         inclusion in the Proxy Statement and registration statement and is so 
         included as so supplied) shall contain (in the case of information 
         relating to the Proxy Statement, at the time it is mailed and in the 
         case of information relating to the registration statement at the time 
         it becomes effective and at the time of MID STATES' shareholders' 
         meeting) any untrue statement of a material fact or shall omit to 
         state a material fact necessary to make the statements contained 
         therein, in light of the circumstances in which they are made, not 
         misleading.  The registration statement and any amendments or 
         supplements thereto that are filed with the SEC in connection with the 
         transactions contemplated hereby will comply as to form in all 
         material respects with the provisions of the 1933 Act and the rules 
         and regulations promulgated thereunder.

    (n)  No employee of BANC ONE or any of its subsidiaries is represented, for 
         purposes of collective bargaining, by a labor organization of any 
         type.  BANC ONE is unaware of any efforts during the past five years 
         to unionize or organize any employees of BANC ONE or any of its 
         subsidiaries, and no claim related to such employees under the Fair 
         Labor Standards Act, National Labor Relations Act, Civil Rights Act of 
         1964, Walsh-Healy Act, Davis Bacon Act, Civil Rights Act of 1866, Age 
         Discrimination in Employment Act, Equal Pay Act of 1963, Executive 
         Order No. 11246, Federal Unemployment Tax Act, Vietnam Era Veterans 
         Readjustment Act, Occupational Safety and Health Act, or any state or 
         local employment related law, order, ordinance or regulation, no 
         unfair labor practice, discrimination or wage-and-hour claim is 
         pending or, to the best of BANC ONE's knowledge, threatened against 
         BANC ONE or any of its subsidiaries which claim has had or is 
         reasonably likely to have a Material Adverse Effect.

    (o)  To the actual knowledge of BANC ONE and its executive officers:  (i) 
         with respect to any contaminant, pollutant, hazardous substance, 
         hazardous waste, hazardous pollutant, toxic pollutant, toxic waste or 
         toxic substance ("Contaminant"), there are no material actions, 
         proceedings or investigations pending or threatened before any federal 
         or state environmental regulatory body, or before any federal or state 
         court, alleging non-compliance with or liability in connection with, 
         by BANC ONE or any of its subsidiaries, the Comprehensive 
         Environmental Response, Compensation and Liability Act, 42 U.S.C. 
         Sections 
         9601 et seq. ("CERCLA"), the Resource Conservation and Recovery Act, 
         42 U.S.C. Sections 6901 et seq. ("RCRA"), the Clean Water Act, 
         33 U.S.C. Sections 
         1251 et seq. ("CWA"), or the Clean Air Act, 42 U.S.C. Sections 7401 
         et seq. 
         ("CAA"), as each is amended from time to time, or any other federal, 
         state, local or municipal statute, ordinance or regulation, or order, 
         ruling or other decision of any court, administrative agency or other 
         governmental authority relating to health or safety or environmental 
         protection (such statutes, ordinances, regulations, orders, rulings 
         and decisions, together, "Environmental Laws"); (ii) there is no 
         reasonable basis for the institution of any material action, 
         proceeding or investigation against BANC ONE or any of its 
         subsidiaries under any Environmental Law; (iii) neither BANC ONE nor 
         any of its subsidiaries is responsible in any material respect under 
         any Environmental Law for any release by any person at or in the 
         vicinity of real property of any Contaminant, caused by the spilling, 
         leaking, pumping, pouring, emitting, emptying, discharging, injecting, 
         escaping, leaching, dumping or disposing of any such hazardous 
         substance into the environment (collectively "Release"); (iv) neither 
         BANC ONE nor any of its subsidiaries is responsible for any material 
         costs of any response action required by virtue of any Release of any 
         Contaminant into the environment including, without limitation, costs 
         arising from investigation, removal or remediation of Contaminants, 
         security fencing, alternative water supplies, temporary evacuation and 
         housing and other emergency assistance undertaken by any environmental 
         regulatory body or any other person; (v) BANC ONE and each of its 
         subsidiaries are, in all material respects, in compliance with all 
         applicable Environmental Laws; and (vi) no real property owned or used 
         by BANC ONE or any of its subsidiaries contains any Contaminant 
         including, without limitation, any asbestos, PCBs or petroleum 
         products or byproducts in any form, the presence, location or 
         condition of which (a) could require remediation or other corrective 
         action pursuant to any Environmental Law in any material respect, or 
         (b) otherwise would pose any significant health or safety risk unless 
         remedial measures were taken.

    (p)  BANC ONE and/or its subsidiaries (i) have surveyed the facilities 
         where BANC ONE and its subsidiaries conduct their businesses 
         including, without limitation, automatic teller machines 
         (collectively, the "BANC ONE Facilities") for compliance with the 
         Americans with Disabilities Act and the regulations issued thereunder 
         (collectively, "ADA"); (ii) have developed action plans to remove 
         architectural barriers including communication barriers that are 
         structural in nature from existing BANC ONE Facilities (collectively, 
         the "BANC ONE Barriers") when such removal is "readily achievable," as 
         that term is defined in ADA; (iii) will finalize action plans for 
         automatic teller machines ("ATMs") upon clarification by the 
         Architectural and Transportation Barriers Compliance Board ("ATBCB"); 
         (iv) have developed or will develop schedules for BANC ONE Barrier 
         removal from BANC ONE Facilities in such action plans so that BANC ONE 
         Barrier removal will be complete on January 26, 1992 or as soon as 
         practicable thereafter; and (v) have removed all BANC ONE Barriers in 
         BANC ONE Facilities or will cause all BANC ONE Barriers to be removed 
         in accordance with such action plans.  All "alterations" (as such term 
         is defined in ADA) to BANC ONE Facilities undertaken after January 26, 
         1992 comply with ADA and the ATBCB Accessibility Guidelines for 
         Buildings and Facilities ("ADAAG").  Effective January 26, 1992, all 
         plans and designs for new construction to be utilized by BANC ONE and 
         its subsidiaries comply with ADA and ADAAG.  To the best of BANC ONE's 
         knowledge, after due inquiry, no material investigations, proceedings, 
         or complaints, formal or informal, are pending or threatened against 
         BANC ONE and/or its subsidiaries in connection with BANC ONE 
         Facilities under ADA, ADAAG, or any other state or federal law 
         concerning accessibility for individuals with disabilities.

    (q)  The statements made in the BANC ONE Disclosure Letter and any 
         attachments thereto shall be deemed to constitute representations and 
         warranties of BANC ONE under this Merger Agreement to the same extent 
         as if herein set forth in full.  Anything disclosed in the BANC ONE 
         Disclosure Letter or the attachments thereto shall be considered to 
         have been disclosed for purposes of all representations, warranties 
         and covenants under this Merger Agreement.

    (r)  BANC ONE has filed all reports, statements, forms and documents with 
         the SEC that it was required to file since December 31, 1988 (the "SEC 
         Filings"), all of which have complied in all material respects with 
         all applicable requirements of the 1933 Act and the 1934 Act.  As of 
         their respective dates, each such SEC Filing did not contain any 
         untrue statement of a material fact or omit to state a material fact 
         required to be stated therein or necessary to make the statements 
         therein, in light of the circumstances under which they were made, not 
         misleading.

14. Representations and Warranties of BANC ONE ILLINOIS.  BANC ONE ILLINOIS 
    represents and warrants to MID STATES that, except as set forth in the BANC 
    ONE Disclosure Letter, and except as otherwise indicated below:

    (a)  BANC ONE ILLINOIS is a corporation duly organized and validly existing 
         under the laws of the State of Illinois, is a registered bank holding 
         company under the Bank Holding Company Act of 1956, as amended, and is 
         qualified to do business and is in good standing in the State of 
         Illinois together with all other jurisdictions where it is both 
         required to so qualify and the failure to so qualify would have a 
         Material Adverse Effect, and BANC ONE ILLINOIS has full power and 
         authority (including all licenses, franchises, permits and other 
         governmental authorizations which are legally required) to engage in 
         the business and activities now conducted by it and its subsidiaries.  
         The authorized capital stock of BANC ONE ILLINOIS is, and at the 
         Effective Time will be, 100 shares of common stock, $1.00 par value, 
         of which 100 shares are issued and outstanding, all of which are owned 
         by BANC ONE free and clear of all liens, security interests or other 
         encumbrances.

    (b)  The Board of Directors of BANC ONE ILLINOIS has authorized execution 
         of this Merger Agreement and approved the acquisition of MID STATES as 
         contemplated by said Merger Agreement.  BANC ONE ILLINOIS has all 
         requisite power and authority to enter into this Merger Agreement and, 
         after approval of the Merger by BANC ONE, the sole shareholder of BANC 
         ONE ILLINOIS, BANC ONE ILLINOIS will have the authority to consummate 
         the transactions contemplated hereby.  Subject to shareholder 
         approval, this Merger Agreement constitutes the valid and legally 
         binding obligation of BANC ONE ILLINOIS and this Merger Agreement and 
         the consummation hereof have been duly authorized and approved on 
         behalf of BANC ONE ILLINOIS by all requisite corporate action.  
         Subject to shareholder approval and provided the required approvals 
         are obtained from the Board and the Illinois Commissioner, neither the 
         execution and delivery of this Merger Agreement nor the consummation 
         of the Merger will conflict with, result in the breach of, constitute 
         a default under or accelerate the performance provided by the terms of 
         any law, or any rule or regulation of any governmental agency or 
         authority or any judgment, order or decree of any court, bank 
         regulatory agency or other governmental agency to which BANC ONE 
         ILLINOIS may be subject, any contract, agreement or instrument to 
         which BANC ONE ILLINOIS is a party or by which BANC ONE ILLINOIS is 
         bound or committed, or the Articles of Incorporation or By-laws of 
         BANC ONE ILLINOIS, or constitute an event which with the lapse of time 
         or action by a third party, could to the best of BANC ONE ILLINOIS' 
         knowledge, result in the default under any of the foregoing or result 
         in the creation of any lien, charge or encumbrance upon any of the 
         assets or properties of BANC ONE ILLINOIS or adversely affect the 
         ability of BANC ONE ILLINOIS to consummate the transactions 
         contemplated hereby.

15. Representations and Warranties of MID STATES.  MID STATES represents and 
    warrants to BANC ONE that, except as set forth in MID STATES' disclosure 
    letter to BANC ONE dated May 25, 1993 and delivered to BANC ONE not later 
    than the time of the execution of this Merger Agreement (the "MID STATES 
    Disclosure Letter"), and except as otherwise indicated below:

    (a)  MID STATES is a corporation duly organized and validly existing in 
         good standing under the laws of the State of Delaware, is a registered 
         bank holding company under the Bank Holding Company Act of 1956, as 
         amended, and is qualified to do business and is in good standing in 
         all jurisdictions where it is both required to so qualify and where 
         the failure to so qualify would have a Material Adverse Effect, and 
         MID STATES has full power and authority (including all licenses, 
         franchises, permits and other governmental authorizations which are 
         legally required) to engage in the businesses and activities now 
         conducted by it and the Subsidiaries.  MID STATES is not subject to 
         any formal or informal agreement or understanding with, nor is it 
         subject to any order of, any bank regulatory authority restricting or 
         prohibiting or attempting to restrict or prohibit any activities or 
         conduct of MID STATES.  As of March 31, 1993, the authorized capital 
         stock of MID STATES consisted of 750,000 shares of MID STATES Common, 
         311,560 of which shares were issued and outstanding and 3,040 of which 
         were treasury shares owned by MID STATES.  All of the issued and 
         outstanding shares of MID STATES Common are duly authorized, validly 
         issued, fully paid and nonassessable and none are issued in violation 
         of the pre-emptive rights of any shareholder.  There are no 
         outstanding options, warrants or commitments of any kind related to 
         MID STATES' capital stock.

    (b)  MID STATES has furnished to BANC ONE copies of the following financial 
         statements relating to MID STATES and the Subsidiaries on a 
         consolidated basis:  (i) the audited Consolidated Balance Sheet of MID 
         STATES as of December 31, 1992 and 1991, and the Consolidated 
         Statements of Income, Stockholders' Equity and Cash Flows for the 
         years then ended, together with the notes thereto, as audited by 
         McGladrey & Pullen, Certified Public Accountants; and (ii) the 
         unaudited Consolidated Balance Sheet of MID STATES as at March 31, 
         1993 and the unaudited Consolidated Statements of Income and Cash 
         Flows for the period then ended, together with the notes thereto.  
         Each of the aforementioned financial statements presents fairly, in 
         accordance with generally accepted accounting principles (applied on a 
         consistent basis except as disclosed in the footnotes thereto), the 
         consolidated financial position and results of operations of MID 
         STATES as of the dates and for the periods therein set forth.  Such 
         financial statements do not, as of the dates thereof, include any 
         material asset or omit any material liability, absolute or contingent, 
         or other fact, the inclusion or omission of which renders such 
         financial statements, in light of the circumstances under which they 
         were made, misleading in any material respect.  Since March 31, 1993, 
         there has not been any change in the financial condition, results of 
         operations or business of MID STATES and the Subsidiaries that has had 
         a Material Adverse Effect.

    (c)  The Board of Directors of MID STATES has duly authorized the execution 
         and delivery of this Merger Agreement and approved the Merger as 
         contemplated by the Merger Agreement and will recommended it to the 
         MID STATES shareholders for adoption.  Subject to the approval by the 
         shareholders of MID STATES and the contemplated regulatory approvals, 
         this Merger Agreement constitutes the valid, legally binding and 
         enforceable obligation of MID STATES and MID STATES has all requisite 
         power and authority to enter into this Merger Agreement and MID STATES 
         has the authority to consummate the transactions contemplated hereby 
         so that, provided all required corporate and regulatory approvals are 
         obtained, neither the execution and delivery of this Merger Agreement 
         nor the consummation of the Merger will conflict with, result in the 
         breach of, constitute a default under or accelerate the performance 
         provided by the terms of any law, or any rule or regulation of any 
         governmental agency or authority or any judgment, order or decree of 
         any court, bank regulatory agency or other governmental agency to 
         which MID STATES is subject, any contract, agreement or instrument to 
         which MID STATES is a party or by which MID STATES is bound or 
         committed, or the Certificate of Incorporation or By-Laws of MID 
         STATES, or constitute an event which with the lapse of time or action 
         by a third party, could, to the best of MID STATES' knowledge, result 
         in the default under any of the foregoing or result in the creation of 
         any lien, charge or encumbrance upon any of the assets or properties 
         of MID STATES or upon any of MID STATES' capital stock; except, in the 
         case of contracts, agreements or instruments, such defaults, conflicts 
         or breaches which either (i) will be cured or waived prior to the 
         Effective Time or (ii) if not so cured or waived would not, in the 
         aggregate, have a Material Adverse Effect.

    (d)  The reserve for possible loan and lease losses shown on the March 31, 
         1993 Consolidated Balance Sheet of MID STATES and its Subsidiaries 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, without limitation, accrued interest 
         receivable) as of March 31, 1993.

    (e)  Except as disclosed in the financial statements referred to in Section 
         15(b), there is no litigation, action, suit, investigation or 
         proceeding pending or, to the best of the knowledge after due inquiry 
         of MID STATES and its executive officers, overtly threatened, against 
         or affecting MID STATES or any of its Subsidiaries or involving any of 
         their respective properties or assets, at law or in equity, before any 
         federal, state, municipal, local or other governmental authority which 
         is reasonably likely to be resolved adversely to the interest of MID 
         STATES or its Subsidiaries and, if so resolved, would have a Material 
         Adverse Effect, and to the best of the knowledge and belief after due 
         inquiry of MID STATES and its executive officers, no one has 
         reasonable or valid grounds on which it reasonably can be expected 
         that anyone will assert or initiate any such litigation, action, suit, 
         investigation or proceeding against MID STATES or any of the 
         Subsidiaries based upon the wrongful action or inaction of MID STATES 
         or any of the Subsidiaries or any of their respective officers, 
         directors or employees.

    (f)  MID STATES and its Subsidiaries have good and marketable title to all 
         their respective assets and properties, whether real or personal, 
         tangible or intangible, including without limitation the capital stock 
         of its Subsidiaries and all other assets and properties reflected in 
         MID STATES' Consolidated Balance Sheet as of March 31, 1993 or 
         acquired subsequent thereto (except to the extent that such assets and 
         properties have been disposed of for fair value in the ordinary course 
         of business since March 31, 1993).  Such assets and properties are 
         subject to no liens, mortgages, security interests, encumbrances, 
         pledges or charges of any kind, except (i) as reflected in said 
         Balance Sheet or the notes thereto; (ii) statutory liens for taxes not 
         yet delinquent; (iii) landlord's liens; and (iv) 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 
         such liens, mortgages, security interests, encumbrances and charges do 
         not, in the aggregate, have a Material Adverse Effect.  MID STATES and 
         its Subsidiaries as lessee have the right under valid and subsisting 
         leases to occupy, use, possess and control all property leased by MID 
         STATES and its Subsidiaries.  At the Effective Time all limitations 
         affecting such properties will not, in the aggregate, have a Material 
         Adverse Effect.

    (g)  To the best of the knowledge after due inquiry of MID STATES and its 
         executive officers, MID STATES and its Subsidiaries have complied with 
         all laws, regulations and orders applicable to them and to the conduct 
         of their businesses, including without limitation, all statutes, rules 
         and regulations pertaining to the conduct of banking activities except 
         for violations which together with any penalty which results therefrom 
         has not had and will not have a Material Adverse Effect.  Neither MID 
         STATES nor any of its Subsidiaries is in default under, and no event 
         has occurred which, to the best of MID STATES' knowledge, after due 
         inquiry, is likely to result in the default under the terms of any 
         judgment, decree, order, writ, rule or regulation of any governmental 
         authority or court, whether federal, state or local and whether at law 
         or in equity, in each case where the default has had or is likely to 
         have a Material Adverse Effect.

    (h)  MID STATES has not, since March 31, 1993 to the date hereof, (i) sold 
         or issued any corporate debt securities or sold, issued, reissued or 
         increased its shares of its capital stock; (ii) granted any option for 
         the purchase of capital stock; (iii) declared or set aside or paid any 
         dividend or other distribution in respect of its capital stock, except 
         as permitted pursuant to Section 16(a) hereof or as incurred in 
         carrying out the transactions contemplated by this Merger Agreement, 
         or directly or indirectly, purchased, redeemed or otherwise acquired 
         any shares of such stock; (iv) incurred any obligation or liability 
         (absolute or contingent) except obligations or liabilities incurred in 
         the ordinary course of business, or mortgaged, pledged or subjected to 
         lien or encumbrance (other than landlord's liens and statutory liens 
         for taxes not yet delinquent and banking transactions conducted in the 
         ordinary course of business) on any of its material assets or 
         properties; (v) discharged or satisfied any material lien or 
         encumbrance or paid any material obligation or liability (absolute or 
         contingent), other than current liabilities included in MID STATES' 
         financial statements as of March 31, 1993, current liabilities 
         incurred since the date thereof in the ordinary course of business and 
         liabilities incurred in carrying out the transactions contemplated by 
         this Merger Agreement; (vi) sold, exchanged or otherwise disposed of 
         any material capital assets; (vii) made any extraordinary officers' 
         salary increase or wage increase, entered into any employment contract 
         with any officer or salaried employee or instituted any employee 
         welfare, bonus, stock option, profit-sharing, retirement or similar 
         plan or arrangement; (viii) suffered any damage, destruction or loss, 
         whether or not covered by insurance, that has had a Material Adverse 
         Effect or waived any rights of value which, in the aggregate, have had 
         a Material Adverse Effect; (ix) entered or agreed to enter into any 
         agreement or arrangement granting any preferential right to purchase 
         any of its material assets, properties or rights or requiring the 
         consent of any party to the transfer and assignment of any such 
         material assets, properties or rights; or (x) entered into any other 
         material transaction (other than in the ordinary course of business) 
         except as expressly contemplated by this Merger Agreement.

    (i)  Except as set forth in the MID STATES Document List (the "MID STATES 
         Document List") attached to the MID STATES Disclosure Letter, neither 
         MID STATES nor any of its Subsidiaries is a party to or bound by any 
         written or oral (i) employment or consulting contract which is not 
         terminable by MID STATES or its Subsidiaries on 60 days or less 
         notice, (ii) employee bonus, deferred compensation, pension, stock 
         bonus or purchase, profit-sharing, retirement or stock option plan, 
         (iii) other employee benefit or welfare plan, or (iv) other executory 
         material agreements as defined by the instructions to Exhibit 10 under 
         Item 601 of SEC Regulation S-K.  All such pension, stock bonus or 
         purchase, profit-sharing, retirement, health and welfare plans (other 
         than any multiemployer plans) set forth in the MID STATES Document 
         List are in this section hereinafter referred to collectively as the 
         "Plans."  Those Plans intended to be qualified plans under Section 
         401(a) of the Code meet any applicable requirements for favorable tax 
         treatment under the Code.  All of the Plans which constitute employee 
         pension benefit plans or employee welfare plans subject to ERISA have 
         been maintained in compliance in all material respects with the 
         applicable requirements of ERISA.  All material notices, reports and 
         other filings required under applicable law to be given or made to or 
         with any governmental agency with respect to the Plans have been 
         timely filed or delivered.  MID STATES has no knowledge of any 
         circumstances which would adversely affect the qualification of the 
         Plans or their compliance with the applicable requirements of ERISA, 
         would result or have resulted in liability under Title IV of ERISA or 
         of any unreported "reportable event" (as such term is defined in 
         Section 4043(b) of ERISA) or any "prohibited transaction" (as such 
         term is defined in Section 406 of ERISA and Section 4975(c) of the 
         Code) which has occurred since the date on which said sections became 
         applicable to the Plans and which could reasonably be expected to 
         result in any material liability of MID STATES or any Subsidiary to 
         the PBGC, the Department of Treasury, the Department of Labor or any 
         multiemployer plan.  Those Plans which are defined benefit plans 
         within the meaning of ERISA meet the minimum funding standards set 
         forth in the Code and ERISA and the assets of such Plans equal or 
         exceed the present value of accrued benefits on a termination basis 
         under such Plans as of the most recent plan valuation date.  There are 
         no pending or threatened claims (other than claims for benefits in the 
         ordinary course), lawsuits or arbitrations which have been asserted or 
         instituted against the Plans, any fiduciaries thereof with respect to 
         their duties to the Plans or the assets of any of the trusts under any 
         of the Plans which could reasonably be expected to result in any 
         material liability of MID STATES or any of its Subsidiaries to the 
         PBGC, the Department of Treasury, the Department of Labor or any 
         multiemployer plan.

    (j)  MID STATES and/or its Subsidiaries have duly filed all federal, state, 
         county and local income, franchise, bank, excise, real and personal 
         property and other tax returns and reports (including, but not limited 
         to, those relating to social security, withholding, unemployment 
         insurance, and occupation, sales, and use taxes and those filed on a 
         consolidated, combined or unitary basis) required to have been filed 
         by MID STATES or its Subsidiaries up to the date hereof.  MID STATES 
         has made available to BANC ONE a copy of its Federal income tax return 
         for the year 1991 and will make available to BANC ONE a copy of its 
         Federal income tax return for the year 1992 when it is filed.  All of 
         the foregoing returns are true and correct in all material respects, 
         and MID STATES and its Subsidiaries have paid or, prior to the 
         Effective Time, will pay all taxes, interest, additions to tax, and 
         penalties shown on such returns or reports as being due or (except to 
         the extent the same are contested in good faith and, if material, 
         summarized in the MID STATES Disclosure Letter) claimed to be due to 
         any federal, state, county, local or other taxing authority, and there 
         is, and at the Effective Time will be, no basis for any additional 
         claim or assessment which might materially and adversely affect MID 
         STATES and its Subsidiaries, except for those being contested in good 
         faith and summarized in the MID STATES Disclosure Letter.  MID STATES 
         and its Subsidiaries have paid or made adequate provision in their 
         financial statements or on their books and records for all taxes 
         payable in respect of all periods ending on or before the date 
         hereof.  MID STATES and its Subsidiaries have, or at the Effective 
         Time will have, no liability for any taxes, interest, additions to 
         tax, or penalties of any nature whatsoever, except for those taxes 
         which may have arisen up to the Effective Time in the ordinary course 
         of business and are properly accrued on the books of MID STATES and 
         the Subsidiaries as of the Effective Time or are being contested in 
         good faith and have, if material, been summarized in the MID STATES 
         Disclosure Letter.

    (k)  MID STATES and the Subsidiaries have in effect insurance coverage with 
         reputable insurers which in respect of amounts, premiums, types and 
         risks insured, constitutes reasonably adequate coverage against all 
         risks customarily insured against by bank holding companies and their 
         subsidiaries comparable in size and operations to MID STATES and the 
         Subsidiaries.

    (l)  MID STATES has not incurred and will not incur any liability for 
         brokerage, finders', agents', or investment bankers' fees or 
         commissions in connection with this Merger Agreement or the 
         transactions contemplated hereby except for fees to DLJ to be 
         determined in accordance with the terms of that certain engagement 
         letter dated November 6, 1992 annexed as an exhibit to the MID STATES 
         Disclosure Letter.

    (m)  MID STATES has annexed to the MID STATES Disclosure Letter a loan 
         schedule identifying certain loan agreements, notes and borrowing 
         arrangements (the "MID STATES Loan Schedule") between its Subsidiaries 
         and borrowers of its Subsidiaries, as of the date hereof.  Except as 
         specifically noted on the MID STATES Loan Schedule, no Subsidiary is, 
         as of the date hereof, a party to any written or, to MID STATES' 
         actual knowledge, oral (i) loan agreement, note or borrowing 
         arrangement, other than credit card loans and other loans the unpaid 
         balance of which does not exceed $100,000 per loan, under the terms of 
         which the obligor is over 60 days delinquent in payment of principal 
         or interest or, to the best of MID STATES' knowledge, in default of 
         any other provision as of the dates shown thereon; (ii) loan 
         agreement, note or borrowing arrangement which has been classified as 
         "substandard," "doubtful," "loss," "other loans especially mentioned" 
         or any comparable classifications by MID STATES, a Subsidiary or 
         banking regulator; (iii) loan agreement, note, or borrowing 
         arrangement, including any loan guaranty, with any director, executive 
         officer or ten percent shareholder of MID STATES, or to the actual 
         knowledge of MID STATES and its executive officers, after due inquiry, 
         any person, corporation or enterprise controlling, controlled by or 
         under common control with any of the foregoing; or, (iv) to the best 
         of MID STATES' knowledge, loan agreement, note or borrowing 
         arrangement in violation of any law, regulation or rule of any 
         governmental authority and which violation could, to the best of MID 
         STATES' knowledge after due inquiry, have a Material Adverse Effect.

    (n)  None of the information provided by MID STATES to BANC ONE for 
         inclusion in the Proxy Statement or related registration statement or 
         any amendment or supplement thereto (to the extent so included as so 
         provided) shall contain (in the case of information relating to the 
         Proxy Statement, at the time it is mailed and in the case of 
         information relating to the registration statement, at the time it 
         becomes effective) any untrue statement of a material fact or shall 
         omit to state a material fact necessary to make the statements 
         contained therein, in light of the circumstances in which they are 
         made, not misleading.  The Proxy Statement that is filed with the SEC 
         in connection with the meeting of the shareholders of MID STATES will 
         comply as to form in all material respects with the provisions of the 
         1934 Act and the rules and regulations promulgated thereunder.

    (o)  MID STATES has annexed a contracts schedule (the "MID STATES Contracts 
         Schedule") to the MID STATES Disclosure Letter setting forth certain 
         material contracts, including credit agreements, on which MID STATES 
         or any of its Subsidiaries is the obligor, maker, issuer or guarantor 
         as of the date hereof.  Except as specifically disclosed on the MID 
         STATES Contracts Schedule, neither MID STATES nor any Subsidiary is, 
         as of the date hereof, a party to any material contract and/or any 
         material credit agreement as obligor, maker, issuer or guarantor and 
         which contract or agreement contains covenants which make the 
         acquisition of MID STATES or any Subsidiary by or merger with another 
         entity a condition of default or acceleration.

    (p)  Attached hereto as Exhibit A is MID STATES' Subsidiaries List which 
         sets forth the complete legal name of each Subsidiary, a designation 
         of the laws under which each Subsidiary is incorporated, the 
         activities conducted by each Subsidiary and the regulatory approvals, 
         if any, requested and/or obtained by MID STATES and each such 
         Subsidiary in connection with the acquisition of each such Subsidiary 
         and/or regulatory approvals received by MID STATES and its 
         Subsidiaries necessary to engage in such activities.  Except as set 
         forth in Exhibit A, MID STATES has no subsidiaries.  Each of the 
         Subsidiaries is a corporation or similar entity duly organized and 
         validly existing in good standing under the laws of the United States 
         or the state of its incorporation and has full power and authority 
         (including all licenses, franchises, permits and other governmental 
         authorizations which are legally required) to engage in the businesses 
         and activities now conducted by it and is duly qualified to do 
         business and is in good standing in all jurisdictions where the 
         failure to so qualify (together with all such failures) would have a 
         Material Adverse Effect.  Except as may be set forth in Exhibit A, MID 
         STATES and/or one or more of its Subsidiaries owns beneficially and of 
         record all the outstanding shares of capital stock of each Subsidiary, 
         which stock is fully paid and non-assessable, except as provided by 
         law.  Neither MID STATES nor any of its Subsidiaries is a party to any 
         partnership or joint venture except as may be set forth and described 
         in Exhibit A.

    (q)  No employee of MID STATES or any of its Subsidiaries is represented, 
         for purposes of collective bargaining, by a labor organization of any 
         type.  MID STATES is unaware of any efforts during the past five years 
         to unionize or organize any employees of MID STATES or any of its 
         Subsidiaries, and no claim related to such employees under the Fair 
         Labor Standards Act, National Labor Relations Act, Civil Rights Act of 
         1964, Walsh-Healy Act, Davis Bacon Act, Civil Rights Act of 1866, Age 
         Discrimination in Employment Act, Equal Pay Act of 1963, Executive 
         Order No. 11246, Federal Unemployment Tax Act, Vietnam Era Veterans 
         Readjustment Act, Occupational Safety and Health Act, or any state or 
         local employment related law, order, ordinance or regulation, no 
         unfair labor practice, discrimination or wage-and-hour claim is 
         pending or, to the best of MID STATES' knowledge, threatened against 
         MID STATES or its Subsidiaries, which claim has had or is reasonably 
         likely to have a Material Adverse Effect.

    (r)  To the actual knowledge of MID STATES and its executive officers:  (i) 
         with respect to any Contaminant, there are no material actions, 
         proceedings or investigations pending or threatened before any federal 
         or state environmental regulatory body, or before any federal or state 
         court, alleging non-compliance with or liability in connection with, 
         by MID STATES or any Subsidiary, CERCLA or any other Environmental 
         Laws; (ii) there is no reasonable basis for the institution of any 
         material action, proceeding or investigation against MID STATES or any 
         Subsidiary under any Environmental Law; (iii) neither MID STATES nor 
         any Subsidiary is responsible in any material respect under any 
         Environmental Law for any Release; (iv) neither MID STATES nor any 
         Subsidiary is responsible for any material costs of any response 
         action required by virtue of any Release of any Contaminant into the 
         environment including, without limitation, costs arising from 
         investigation, removal or remediation of Contaminants, security 
         fencing, alternative water supplies, temporary evacuation and housing 
         and other emergency assistance undertaken by any environmental 
         regulatory body or any other person; (v) MID STATES and each 
         Subsidiary is, in all material respects, in compliance with all 
         applicable Environmental Laws; and (vi) no real property owned or used 
         by MID STATES or any Subsidiary contains any Contaminant including, 
         without limitation, any asbestos, PCBs or petroleum products or 
         byproducts in any form, the presence, location or condition of which 
         (a) could require remediation or other corrective action pursuant to 
         any Environmental Law in any material respect, or (b) otherwise would 
         pose any significant health or safety risk unless remedial measures 
         were taken.

    (s)  MID STATES and/or the Subsidiaries (i) have surveyed the facilities 
         where MID STATES and the Bank conduct their businesses including, 
         without limitation, ATMs (collectively, the "MID STATES Facilities") 
         for compliance with ADA; (ii) have developed action plans to remove 
         architectural barriers including communication barriers that are 
         structural in nature from existing MID STATES Facilities 
         (collectively, the "MID STATES Barriers") when such removal is 
         "readily achievable," as that term is defined in ADA; (iii) will 
         finalize action plans for ATMs upon clarification by the ATBCB; (iv) 
         have developed or will develop schedules for MID STATES Barrier 
         removal from MID STATES Facilities in such action plans so that MID 
         STATES Barrier removal will be complete on January 26, 1992 or as soon 
         as practicable thereafter; and (v) have removed all MID STATES 
         Barriers in MID STATES Facilities or will cause all MID STATES 
         Barriers to be removed in accordance with such action plans.  All 
         "alterations" (as such term is defined in ADA) to MID STATES 
         Facilities undertaken after January 26, 1992 comply with ADA and the 
         ADAAG.  Effective January 26, 1992, all plans and designs for new 
         construction to be utilized by MID STATES and the Subsidiaries comply 
         with ADA and ADAAG.  To the best of MID STATES' knowledge, after due 
         inquiry, no material investigations, proceedings, or complaints, 
         formal or informal, are pending or threatened against MID STATES 
         and/or the Subsidiaries in connection with MID STATES Facilities under 
         ADA, ADAAG, or any other state or federal law concerning accessibility 
         for individuals with disabilities.

    (t)  The statements made and the information included in the MID STATES 
         Disclosure Letter and any attachments thereto shall be deemed to 
         constitute representations and warranties of MID STATES under this 
         Merger Agreement to the same extent as if herein set forth in full.  
         Anything disclosed in the MID STATES Disclosure Letter or the 
         attachments thereto shall be considered to have been disclosed for 
         purposes of all representations, warranties and covenants under this 
         Merger Agreement.

    (u)  There are no credit agreements on which MID STATES or any of the 
         Subsidiaries is the maker, issuer or guarantor and which contain 
         provisions which make the acquisition of MID STATES by or merger into 
         another entity a condition of default or acceleration.

16. Action by MID STATES Pending Effective Time.  MID STATES agrees that from 
    the date of this Merger Agreement until the earlier of the Effective Time 
    or the time that this Merger Agreement is terminated,  except with the 
    prior written permission of BANC ONE, which, in any case covered by Section 
    16(d) hereof, shall not be unreasonably withheld:

    (a)  Beginning with the first calendar quarter of 1993 and for each 
         succeeding calendar quarter thereafter prior to that calendar quarter 
         in which the Effective Time shall occur, MID STATES

         (i)   will not declare or pay any dividends or make any distributions 
               on shares of MID STATES Common, except cash dividends which 
               shall be equal to either:  (a) $0.65 per share per quarter or 
               (b) that amount per share per quarter calculated by multiplying 
               the amount paid by BANC ONE on each share of BANC ONE Common for 
               such quarter times the Exchange Rate;

         (ii)  except as hereinbelow provided, will not declare or pay any 
               dividends or make any distributions in any amount on its MID 
               STATES Common in the quarter in which the Effective Time shall 
               occur and in which the shareholders of MID STATES Common are 
               entitled to receive regular quarterly dividends on the shares of 
               BANC ONE Common into which the shares of MID STATES Common have 
               been converted.  It is the intent of this part (ii) to provide 
               that the holders of MID STATES Common will receive either the 
               payment of cash dividends on their shares of MID STATES Common 
               or the payment of cash dividends as the holders of shares of 
               BANC ONE Common received in exchange for the shares of MID 
               STATES Common for the calendar quarter during which the 
               Effective Time shall occur, but will not receive and will not 
               become entitled to receive for the same calendar quarter both 
               the payment of a cash dividend as shareholders of MID STATES and 
               the payment of a cash dividend as the holders of the shares of 
               BANC ONE Common received in exchange for the shares of MID 
               STATES Common.  In the event that MID STATES does not declare 
               and pay cash dividends on its MID STATES Common in a particular 
               calendar quarter because of MID STATES' reasonable expectation 
               that the Effective Time would occur in said calendar quarter 
               wherein the holders of MID STATES Common would have become 
               entitled to receive cash dividends for such calendar quarter on 
               the shares of BANC ONE Common to have been exchanged for the 
               shares of MID STATES Common, and the Effective Time does not in 
               fact occur effective in said calendar quarter, then, as a result 
               thereof, MID STATES shall be entitled to declare and pay a cash 
               dividend (within the limitations of this Section 16) on said 
               shares of MID STATES Common for said calendar quarter as soon as 
               reasonably practicable.

         The declaration of any dividends within the limitations of this 
         paragraph shall remain within the discretion of the Board of Directors 
         of MID STATES.

    (b)  MID STATES will not issue, sell, grant any option for, or acquire for 
         value any shares of its capital stock or otherwise effect any change 
         in connection with its equity capitalization.

    (c)  Except as otherwise set forth in or contemplated by this Merger 
         Agreement, MID STATES will carry on its businesses in substantially 
         the same manner as heretofore, use its reasonable best efforts to keep 
         in full force and effect insurance comparable in amount and scope of 
         coverage to that now maintained by it and use its reasonable best 
         efforts to maintain and preserve its business organization intact.

    (d)  Neither MID STATES nor any Subsidiary will (i) enter into any new line 
         of business or incur or agree to incur any obligation or liability 
         except liabilities and obligations (including corporate debt 
         issuances) incurred in the ordinary course of business, except as may 
         be directed by any regulatory agency; (ii) except as may be directed 
         by any regulatory agency, change its or the Subsidiaries' lending, 
         investment, liability management and other material banking policies 
         in any material respect; (iii) except in the ordinary course of 
         business and consistent with prior practice, grant any general or 
         uniform increase in the rates of pay of employees; (iv) establish any 
         new employee benefit plan or amend any existing plan (except as 
         required by law or permitted in the Benefits Letter) so as to increase 
         by any significant amount the benefits payable thereunder; (v) incur 
         or commit to any capital expenditures other than in the ordinary 
         course of business (which will in no event include the establishment 
         of new branches or any other facilities or any capital expenditures in 
         excess of $50,000 for any individual project for any purpose) except 
         any alterations MID STATES, after consultation with BANC ONE, decides 
         are required by the Americans with Disabilities Act or referenced in 
         the MID STATES Disclosure Letter; or (vi) merge into, consolidate with 
         or permit any other corporation to be merged or consolidated with it 
         or any of its Subsidiaries or acquire outside of the ordinary course 
         of business part of or all the assets or stock of any other 
         corporation or person.

    (e)  MID STATES will not change its or its Subsidiaries' methods of 
         accounting in effect at December 31. 1992, except as required by 
         changes in generally accepted accounting principles as concurred in by 
         McGladrey & Pullen, or change any of its methods of reporting income 
         and deductions for Federal income tax purposes from those employed in 
         the preparation of MID STATES' Federal income tax returns for the 
         taxable years ending December 31, 1992 and 1991, except as required by 
         changes in law or regulation.

    (f)  MID STATES will afford BANC ONE, its officers and other authorized 
         representatives, such access to all books, records, bank examination 
         reports (as permitted by law), tax returns, leases, contracts and 
         documents of MID STATES and its Subsidiaries and will furnish to BANC 
         ONE such information with respect to the assets and business of MID 
         STATES and its Subsidiaries as BANC ONE may from time to time 
         reasonably request in connection with this Merger Agreement and the 
         transactions contemplated hereby.

    (g)  MID STATES will promptly advise BANC ONE in writing of all material 
         corporate actions taken by the directors and shareholders of MID 
         STATES, furnish BANC ONE with copies of all monthly and other interim 
         financial statements of MID STATES as they become available, and keep 
         BANC ONE fully informed concerning all trends and developments which 
         in the opinion of MID STATES may have a Material Adverse Effect on MID 
         STATES.

    (h)  MID STATES, its Subsidiaries and their respective officers, directors 
         and employees will not contract for or acquire, at the expense of MID 
         STATES or any of its Subsidiaries, a policy or policies providing for 
         insurance coverage for directors, officers and/or employees of MID 
         STATES and/or its Subsidiaries for any period subsequent to the 
         Effective Time for events occurring before or after the Effective 
         Time; provided, however, that MID STATES may renew, extend or replace 
         existing policies in the ordinary course consistent with past 
         practices for periods of not greater than one year.

17. Action by BANC ONE Pending Effective Time.  BANC ONE agrees that from the 
    date of this Merger Agreement until the Effective Time, except with prior 
    written permission of MID STATES:

    (a)  BANC ONE will not adopt or implement any amendment to its Articles of 
         Incorporation or any plan of reorganization which would affect in any 
         manner the terms and provisions of the shares of BANC ONE Common or 
         the rights of the holders of such shares or reclassify the BANC ONE 
         Common.

    (b)  Except as otherwise set forth in or contemplated by this Merger 
         Agreement, BANC ONE will carry on its businesses in substantially the 
         same manner as heretofore, use its reasonable best efforts to keep in 
         full force and effect insurance comparable in amount and scope of 
         coverage to that now maintained by it and use its reasonable best 
         efforts to maintain and preserve its business organization intact.

    (c)  BANC ONE will not change its or its subsidiaries' methods of 
         accounting in effect at December 31, 1992, except as required by 
         changes in generally accepted accounting principles as concurred with 
         by Coopers & Lybrand, its independent auditors, or change any of its 
         methods of reporting income and deductions for Federal income tax 
         purposes from those employed in the preparation of the Federal income 
         tax returns of BANC ONE for the taxable years ending December 31, 1992 
         and 1991, except as required by changes in law or regulation.

    (d)  BANC ONE will afford MID STATES, its officers and other authorized 
         representatives, such access to all books, records, bank examination 
         reports (as permitted by law), tax returns, leases, contracts and 
         documents of BANC ONE and its subsidiaries and will furnish to MID 
         STATES such information with respect to the assets, earnings and 
         business of BANC ONE and its subsidiaries as MID STATES may from time 
         to time reasonably request in connection with this Agreement and the 
         transactions contemplated hereby.

18. Conditions to Obligations of BANC ONE and BANC ONE ILLINOIS.  The 
    obligations of BANC ONE and BANC ONE ILLINOIS to effect the Merger are 
    subject, unless waived by BANC ONE, to the satisfaction of the following 
    conditions on or prior to the Effective Time:

    (a)  There shall not have been any change in the consolidated financial 
         condition, aggregate net assets, shareholders' equity, business or 
         operating results of MID STATES and its Subsidiaries, taken as a 
         whole, from March 31, 1993 to the Effective Time that has had a 
         Material Adverse Effect.

    (b)  MID STATES shall not have paid cash dividends from March 31, 1993 to 
         the Effective Time except as permitted under this Merger Agreement.

    (c)  All representations by MID STATES contained in this Merger Agreement 
         shall be true in all material respects at, or as of, the Effective 
         Time as though such representations were made at and as of said date, 
         except for changes contemplated by the Merger Agreement, and except 
         also for representations as of a specified time other than the 
         Effective Time, which shall be true in all material respects at such 
         specified time; provided, however, that the representation of MID 
         STATES contained in Section 15(d) shall be true in all material 
         respects as applied to the Balance Sheet of MID STATES included in the 
         most recently available quarterly or annual report to MID STATES 
         shareholders and/or MID STATES' report to the SEC on Form 10-Q or Form 
         10-K as of the close of the most recent calendar quarter prior to the 
         Effective Date (as hereinafter defined) and the reserve for possible 
         loan and lease losses included therein, as though each reference to 
         "March 31, 1993" in such section were a reference to the last day of 
         the most recent calendar quarter prior to the day of the Effective 
         Time (the "Effective Date").

    (d)  BANC ONE shall have received the opinion of legal counsel for MID 
         STATES, dated as of the Effective Time, substantially to the effect 
         set forth in Exhibit D hereto, together with a copy of the Certificate 
         of Incorporation, as amended, of MID STATES certified by the Secretary

         cumulative earnings reported by MID STATES since March 31, 1993 shall 
         be greater than or equal to the amount calculated by multiplying (a)

         pursuant to the provisions of applicable law, shall not be more than

         behalf by the Chairman or President and the Secretary or an Assistant 
         Secretary of MID STATES and dated as of the Effective Time, certifying 
         as to the form of and adoption of resolutions of the Board and 
         shareholders of MID STATES approving the Merger Agreement and the 
         Merger, respectively, and to the effect that the conditions described 
         in Paragraphs (a), (b), (c), (e), (f) and (g) of this Section 18 have 
         been fully satisfied.

19. Conditions to Obligations of MID STATES.  The obligations of MID STATES to

         operating results of BANC ONE and its subsidiaries, taken as a whole, 
         from March 31, 1993 to the Effective Time that has had a Material 
         Adverse Effect.

    (b)  All representations by BANC ONE and BANC ONE ILLINOIS contained in 
         this Merger Agreement shall be true in all material respects at, or as 
         of, the Effective Time as though such representations were made at and 
         as of said date, except for changes contemplated by this Merger 
         Agreement, and except also for representations as of a specified time 
         other than the Effective Time, which shall be true in all material 
         respects at such specified time; provided, however, that the 
         representation of BANC ONE contained in Section 13(d) shall be true in 
         all material respects as applied to the Consolidated Balance Sheet of 
         BANC ONE included in the most recently available quarterly or annual 
         report to BANC ONE's shareholders and/or BANC ONE's report to the SEC

         quarter prior to the Effective Date and the reserve for possible loan 
         and lease losses included therein, as though each reference to "March 
         31, 1993" in such section were a reference to the last day of the most 
         recent calendar quarter prior to the Effective Date.

    (c)  MID STATES shall have received the opinion of counsel for BANC ONE and 
         BANC ONE ILLINOIS (i) on and dated the date on which the registration

         Effective Time shall occur within 20 days following the close of a 
         calendar quarter, then as of the close of the next preceding calendar 
         quarter) cumulative per share earnings reported by BANC ONE since 
         March 31, 1993 shall be greater than or equal to the amount calculated 
         by multiplying (a) $0.96 by (b) the number of full calendar quarters 
         which have passed since March 31, 1993 and for which earnings have 
         been reported as of such date, times (c) 0.9.  As used in this 
         Section, "reported" means reported on BANC ONE's consolidated 
         financial statements prepared in accordance with generally accepted 
         accounting principles applied on a basis consistent with BANC ONE's 
         consolidated financial statements for the years ended December 31, 
         1992 and 1991, as included in BANC ONE's reports to the SEC on Forms 
         10-K or BANC ONE's annual reports to shareholders subject to any 
         subsequent adjustments required to be reported to the SEC whether or 
         not such adjustments have, as yet, been reported.

    (f)  MID STATES shall have received an opinion from DLJ dated as of a date 
         not later than the date of the Proxy Statement, to the effect that, in 
         the opinion of such firm, the financial consideration to be received 
         as a result of the Merger is fair from a financial point of view to 
         the holders of MID STATES Common and such opinion shall not have been 
         withdrawn prior to the Effective Time.

    (g)  BANC ONE shall have furnished MID STATES a certificate, signed by the 
         Chairman or President or an Executive Vice President and by the

20. Conditions to Obligations of All Parties.  In addition to the provisions of 
    Sections 18 and 19 hereof, the obligations of BANC ONE and MID STATES to 
    effect the Merger shall be subject to the satisfaction of the following 
    conditions on or prior to the Effective Time:

    (a)  The parties hereto shall have received all necessary approvals of 
         governmental agencies and authorities of the transactions contemplated 
         by this Merger Agreement and each of such approvals shall remain in 
         full force and effect at the Effective Time.  BANC ONE shall notify 
         MID STATES promptly upon receipt of all necessary governmental 
         approvals.  At the Effective Time, (i) no party hereto shall be 
         subject to any order, decree or injunction of a court or governmental 
         agency of competent jurisdiction which enjoins or prohibits the 
         consummation of the Merger; and (ii) no statute, rule, regulation, 
         order, injunction or decree shall have been enacted, entered, 
         promulgated or enforced by any governmental authority which prohibits 
         or makes illegal consummation of the Merger.

    (b)  The registration statement required to be filed by BANC ONE pursuant 
         to Section 10(d) of this Merger Agreement shall have become effective 
         by an order of the SEC, the shares of BANC ONE Common to be exchanged 
         in the Merger shall have been qualified or exempted under all 
         applicable state securities laws, and there shall have been no stop 
         order issued or threatened by the SEC that suspends or would suspend 
         the effectiveness of the registration statement, and no proceeding by 
         the SEC shall have been commenced, pending or overtly threatened for 
         such purpose and the BANC ONE Common to be issued in the Merger will 
         be authorized for trading on the NYSE.

    (c)  This Merger Agreement and the Merger shall have been duly approved and 
         adopted by the requisite affirmative vote of the shareholders of MID 
         STATES and BANC ONE ILLINOIS.

    (d)  Vedder, Price, Kaufman & Kammholz shall have issued its written 
         opinion, dated as of the day of the Effective Time, satisfactory to 
         MID STATES and BANC ONE, respectively, substantially to the effect set 
         forth in clauses (a) through (h) of Section 12 of this Merger 
         Agreement and there shall exist as of, at or immediately prior to the 
         Effective Time no facts or circumstances which would render such 
         opinion inapplicable in any respect to the transactions to be 
         consummated hereunder.

    (e)  Coopers & Lybrand shall have issued its written opinion, dated as of a 
         date not later than the Effective Time, satisfactory, in good faith, 
         to BANC ONE, advising that the transaction herein contemplated may be 
         properly accounted for as a pooling-of-interests; provided, however, 
         that this condition shall be deemed to have been waived by BANC ONE if 
         the inability to obtain such opinion arises out of, or results 
         directly or indirectly from, any action taken by BANC ONE, BANC ONE 
         ILLINOIS or any of their respective subsidiaries contrary to that 
         contemplated by this Merger Agreement.

21. Indemnification.

    (a)  In the event of any threatened or actual claim, action, suit, 
         proceeding or investigation, whether formal or informal and whether 
         civil, administrative or criminal, including, without limitation, any 
         such claim, action, suit, proceeding or investigation in which any 
         person who is now, or has been at any time prior to the date hereof, 
         or who becomes prior to the Effective Time, a director, officer, 
         employee, fiduciary or agent of MID STATES or any of its Subsidiaries 
         (the "Indemnified Parties") is, or is threatened to be, made a party 
         or a witness, based in whole or in part on, or arising in whole or in 
         part out of, or pertaining to, this Merger Agreement or any of the 
         transactions contemplated hereby (a "Merger Related Event"), whether 
         in any case asserted or arising before or after the Effective Time, 
         the parties hereto agree to cooperate and use their reasonable best 
         efforts to defend against and respond to such claim, action, suit, 
         proceedings or investigation.  It is understood and agreed that, 
         provided that, with regard to any Merger Related Event, and 
         conditioned upon the Merger becoming effective, BANC ONE shall 
         indemnify and hold harmless, as and to the fullest extent permitted by 
         applicable law, each Indemnified Party against any and all losses, 
         claims, damages, liabilities, costs, expenses (including attorneys' 
         fees and expenses), judgments and fines, and amounts paid in 
         settlement, in connection with any such threatened or actual claim, 
         action, suit, proceedings or investigation; provided, however, that 
         BANC ONE shall not be liable for any settlement effected without its 
         prior written consent (which consent shall not be unreasonably 
         withheld).  In the event of any such threatened or actual claim, 
         action, suit, proceedings or investigation (whether asserted or 
         arising before or after the Effective Time), (i) BANC ONE shall pay 
         expenses (including attorney's fees and expenses) in advance of the 
         final disposition of any claim, suit, proceedings or investigation to 
         each Indemnified Party to the fullest extent permitted by applicable 
         law, and (ii) BANC ONE shall use its reasonable best efforts to assist 
         in the vigorous defense of any such matter; provided, however, that 
         BANC ONE's obligations as herein set forth shall not apply to any 
         losses, claims, damages, liabilities, costs, expenses, judgments, 
         fines and amounts paid in settlement by any Indemnified Party 
         involving the fraud, bad faith and/or reckless disregard of such 
         Indemnified Party related to any threatened or actual claim, action, 
         suit, proceedings or investigation brought by BANC ONE against any 
         Indemnified Party.  Any Indemnified Party wishing to claim 
         indemnification under this Section 21(a) shall, upon learning of or 
         having reason to anticipate any such claim, action, suit, proceedings 
         or investigation, immediately notify BANC ONE thereof.

    (b)  BANC ONE shall insure that all rights to indemnification and all 
         limitations of liability existing in favor of the Indemnified Parties 
         as provided in MID STATES's Certificate of Incorporation and By-laws 
         or similar governing documents of any of its Subsidiaries, as in 
         effect as of May 1, 1993, or as provided for or allowed under 
         applicable law as in effect as of the date hereof or as amended at a 
         time prior to the Effective Time, with respect to claims or 
         liabilities arising from facts or events existing or occurring prior 
         to the Effective Time, shall survive the Merger and shall continue in 
         full force and effect, without any amendment thereto, for a period of 
         three (3) years from the Effective Time; provided, however, that all 
         rights to indemnification in respect of any claim asserted or made 
         within such period shall continue until the final disposition of such 
         claim.

    (c)  From and after the Effective Time, persons who, immediately prior to 
         the Effective Time, served as the directors, officers and employees of 
         MID STATES and its Subsidiaries, who, following the Effective Time, 
         continue as directors, officers and/or employees of the Surviving 
         Corporation or one of the Subsidiaries, shall have indemnification 
         rights having prospective application only, except, however, for the 
         indemnification rights set forth in paragraphs (a) and (b) of this 
         Section 21.  These prospective indemnification rights shall consist of 
         (i) such rights to which directors, officers and employees are 
         entitled under the provisions of the Certificate of Incorporation, 
         Bylaws or similar governing documents of the Surviving Corporation and 
         its subsidiaries, as applicable, as in effect from time to time after 
         the Effective Time, as applicable, and provisions of applicable law as 
         in effect from time to time after the Effective Time and (ii) those 
         indemnification rights set forth in agreements, if any, between BANC 
         ONE and the directors and executive officers of the Surviving 
         Corporation and its subsidiaries.  Such agreements, if any, which 
         shall be executed as soon as practicable following the Effective Time, 
         shall provide certain indemnification rights that are comparable to 
         those provided to directors, officers and employees of BANC ONE and 
         its subsidiaries generally, but which rights may be greater or lesser 
         than the indemnification rights available in clause (i) above.

    (d)  The obligations of BANC ONE provided under paragraphs (a) and (b) this 
         Section 21 are intended to be the joint and several obligations of 
         BANC ONE and the Surviving Corporation and to benefit, and be 
         enforceable against BANC ONE and the Surviving Corporation directly 
         by, the Indemnified Parties, and shall be binding on all respective 
         successors and permitted assigns of BANC ONE and the Surviving 
         Corporation.

    (e)  In the event BANC ONE or the Surviving Corporation or any of its 
         successors or assigns (i) consolidates with or merges into any other 
         person and shall not be the continuing or surviving corporation or 
         entity of such consolidation or merger, or (ii) transfers or conveys 
         all or substantially all of its properties and assets to any person, 
         then, and in each such case, proper provision shall be made so that 
         the successors and assigns of BANC ONE or the Surviving Corporation, 
         as the case may be, assume the obligations set forth in this Section 
         21.

22. Non-Survival of Representations and Warranties.  The respective 
    representations and warranties of MID STATES, BANC ONE and BANC ONE 
    ILLINOIS contained in this Merger Agreement shall not survive the Effective 
    Time.

23. Governing Law.  This Merger Agreement shall be construed and interpreted 
    according to the applicable laws of the State of Illinois, except as the 
    laws of the State of Delaware are expressly applicable to the Merger.

24. Assignment.  This Merger Agreement and all of the provisions hereof shall 
    be binding upon and inure to the benefit of the parties hereto and their 
    respective successors and permitted assigns, but neither this Merger 
    Agreement nor any of the rights, interest, or obligations hereunder shall 
    be assigned by any of the parties hereto without the prior written consent 
    of the other parties.

25. Satisfaction of Conditions; Termination.

    (a)  BANC ONE and BANC ONE ILLINOIS agree to use their reasonable best 
         efforts to obtain satisfaction of the conditions of this Merger 
         Agreement insofar as they relate to BANC ONE and BANC ONE ILLINOIS, 
         and MID STATES agrees to use its reasonable best efforts to obtain the 
         satisfaction of the conditions of this Merger Agreement insofar as 
         they relate to MID STATES, in each case as soon as possible.

    (b)  This Merger Agreement may be terminated at any time prior to the 
         Effective Time, whether before or after approval of the Merger by the 
         shareholders of BANC ONE ILLINOIS or by MID STATES' shareholders, upon 
         the occurrence of any of the following by written notice from BANC ONE 
         to MID STATES (authorized by the Board of Directors of BANC ONE), or 
         by written notice from MID STATES to BANC ONE (authorized by the Board 
         of Directors of MID STATES), as the case may be:

         (i)   If any material condition to the obligations of BANC ONE and/or 
               BANC ONE ILLINOIS set forth in Section 18 or 20 is not 
               substantially satisfied at the time or times contemplated 
               thereby and such condition is not waived by BANC ONE or if any 
               material condition to the obligations of MID STATES as set forth 
               in Section 19 or 20 is not substantially satisfied at the time 
               or times contemplated thereby and such condition is not waived 
               by MID STATES, each party's right to terminate under this 
               Section 25 (b)(i) shall relate only to conditions to that 
               party's obligations;

         (ii)  In the event of a material breach by the other of any 
               representation, warranty, condition or agreement contained in 
               this Merger Agreement that is not cured within 30 days of the 
               time that written notice of such breach is received by such 
               other party from the party giving notice; or

         (iii) If the Merger shall not have been consummated on or before May 
               1, 1994.

    (c)  In the event that BANC ONE's pre-acquisition investigation and review 
         of MID STATES as described in Section 10(n) of this Merger Agreement 
         discloses matters which BANC ONE in good faith believes to be either 
         (i) inconsistent in any material respect with any of the 
         representations and warranties of MID STATES contained in this 
         Agreement or (ii), in the reasonable judgment of the Board of 
         Directors of BANC ONE, to be either (x) of such significance as to 
         materially and adversely affect the financial condition or the results 
         of operations of MID STATES and its Subsidiaries on a consolidated 
         basis or (y) to deviate materially and adversely from MID STATES' 
         audited financial statements for the year ended December 31, 1992, 
         BANC ONE shall have the right to terminate this Merger Agreement as 
         set forth in this Section 25(c) as supplemented by the MID STATES 
         Disclosure Letter by giving written notice of termination to MID 
         STATES within seven days of the conclusion of such pre-acquisition 
         investigation.

    (d)  In the event that MID STATES' pre-acquisition investigation and review 
         of BANC ONE as described in Section 10(o) of this Merger Agreement 
         discloses matters which MID STATES in good faith believes to be either 
         (i) inconsistent in any material respect with any of the 
         representations and warranties of BANC ONE contained in this 
         Agreement, or (ii) in the reasonable judgment of the Board of 
         Directors of MID STATES, to be either (x) of such significance as to 
         materially and adversely affect the financial condition or the results 
         of operations of BANC ONE and its subsidiaries on a consolidated basis 
         or (y) to deviate materially and adversely from BANC ONE's audited 
         financial statements for the year ended December 31, 1992, MID STATES 
         may elect to terminate this Merger Agreement by giving written notice 
         of termination to BANC ONE within seven days of the conclusion of such 
         pre-acquisition investigation.

    (e)  In the event the BANC ONE Average Price (as defined in Section 7 of 
         this Merger Agreement) is less than $52.00 per share, MID STATES, by 
         action of its Board of Directors, may elect to terminate this Merger 
         Agreement, whether before or after approval of the Merger by the 
         shareholders of MID STATES or by BANC ONE ILLINOIS shareholders, by 
         giving written notice of such election to BANC ONE within two NYSE 
         trading days after the Valuation Period (as defined in Section 7 of 
         this Merger Agreement).  If prior to the Valuation Period, BANC ONE 
         shall effect a stock dividend or make distributions upon or subdivide, 
         split up, reclassify or combine its shares of the BANC ONE Common, 
         appropriate adjustment or adjustments will be made in the BANC ONE 
         Average Price.

         A termination resulting from MID STATES' election under this Section 
         25(e) shall be deemed to have been a termination by mutual consent of 
         the parties.

    (f)  This Merger Agreement may be terminated and abandoned (whether before 
         or after approval of the Merger by the shareholders of BANC ONE 
         ILLINOIS or by MID STATES' shareholders) by mutual written consent of 
         MID STATES, BANC ONE ILLINOIS and BANC ONE authorized by their 
         respective Boards of Directors.

    (g)  In the event of termination of this Merger Agreement (i) caused 
         otherwise than by a willful breach of this Merger Agreement by any of 
         the parties hereto or (ii) pursuant to Section 25(c) or (d), this 
         Merger Agreement shall cease and terminate, the acquisition of MID 
         STATES as provided herein shall not be consummated, and none of BANC 
         ONE, BANC ONE ILLINOIS nor MID STATES shall have any liability to any 
         other party under this Merger Agreement of any nature whatever, except 
         for BANC ONE's obligations related to the printing of the proxy 
         solicitation materials, including any liability for damages, provided, 
         however, that the duties of the parties with respect to confidential 
         information as set forth in Section 10(f) shall survive any such 
         termination.  If the Merger is not consummated as the result of 
         termination of this Merger Agreement caused otherwise than by willful 
         breach of a party hereto, BANC ONE, BANC ONE ILLINOIS and MID STATES 
         each shall pay its own fees and expenses incident to the negotiation, 
         preparation and execution of this Merger Agreement, the respective 
         shareholders' meetings and actions of the parties and all other acts 
         incidental to, contemplated by or in pursuance of the transactions 
         contemplated by this Merger Agreement, including fees and expenses of 
         their respective counsel, accountants and other experts and advisors.

    (h)  If termination of this Merger Agreement shall be judicially determined 
         to have been caused by willful breach of this Merger Agreement, then, 
         in addition to other remedies at law or equity for breach of this 
         Merger Agreement, the party so found to have willfully breached this 
         Merger Agreement shall indemnify the other parties for their 
         respective costs, fees and expenses of their counsel, accountants and 
         other experts and advisors as well as fees and expenses incident to 
         negotiation, preparation and execution of this Merger Agreement and 
         related documentation and their shareholders' meetings and consents.

26. Waivers; Amendments.  Any of the provisions of this Merger Agreement may be 
    waived at any time by the party which is, or the shareholders of which are, 
    entitled to the benefit thereof, provided, however, such waiver, if 
    material to MID STATES or its shareholders, may be made only following due 
    authorization by the Board of Directors of MID STATES.  This Merger 
    Agreement may be amended or modified in whole or in part by an agreement in 
    writing executed in the same manner (but not necessarily by the same 
    persons) as this Merger Agreement and which makes reference to this Merger 
    Agreement, provided, however, such amendment or modification may be made 
    only following due authorization by the respective Boards of Directors of 
    MID STATES, BANC ONE ILLINOIS and BANC ONE; provided, further, however, 
    that after a favorable vote by the shareholders of MID STATES any such 
    action shall be taken by MID STATES only if, in the opinion of its Board of 
    Directors, such amendment or modification will not have any material 
    adverse effect on the benefits intended under this Merger Agreement for the 
    shareholders of MID STATES and will not require resolicitation of any 
    proxies from such shareholders.

27. Entire Agreement.  Subject to the exceptions noted in the next following 
    sentence, this Agreement supersedes any other agreement, whether written or 
    oral, that may have been made or entered into by MID STATES, BANC ONE 
    ILLINOIS and BANC ONE or by any officer or officers of such parties 
    relating to the acquisition of the business or the capital stock of MID 
    STATES and/or its Subsidiaries by BANC ONE or BANC ONE ILLINOIS.  Except 
    for the BANC ONE Disclosure Letter and any attachment thereto, the MID 
    STATES Disclosure Letter and any attachments thereto, the Benefits 
    Agreement and the Second Benefits Agreement, this Merger Agreement 
    constitutes the entire agreement by the parties, and there are no 
    agreements or commitments except as set forth herein and therein.

28. Captions; Counterparts.  The captions in this Merger Agreement are for 
    convenience only and shall not be considered a part of or affect the

2.  Conversion of Stock.

    (a)  At the Effective Time:

         (i)   Each of the not more than 314,600 shares of MID STATES Common 
               that shall be issued and outstanding immediately prior to the 
               Effective Time (excluding any shares held by MID STATES as 
               treasury shares) shall thereupon and without further action be 
               converted into 1.98 shares of BANC ONE Common, subject, however, 
               to (A) the anti-dilution provisions of Section 2(d) of this 
               Merger Agreement and (B) provisions hereinafter contained 
               relative to fractional shares (the "Exchange Rate").

         (ii)  The 100 shares of BANC ONE ILLINOIS Common issued and 
               outstanding immediately prior to the Effective Time shall 
               continue to be issued and outstanding shares of common stock 
               without par value of the Surviving Corporation.

         (iii) All of the shares of MID STATES Common held by MID STATES as 
               treasury shares immediately prior to the Effective Time shall be 
               cancelled and shall not represent capital stock of the Surviving 
               Corporation and shall not be exchanged for shares of BANC ONE 
               Common.

    (b)  MID STATES' shareholders of record at the Effective Time, for the 
         shares of MID STATES Common then held by them, respectively, shall be 
         allocated and be entitled to receive (upon surrender of certificates 
         formerly representing shares of MID STATES Common for cancellation) 
         certificates for shares of BANC ONE Common as shall be equal to the 
         number of shares of MID STATES Common outstanding immediately prior to 
         the Effective Time multiplied by the Exchange Rate.

    (c)  No certificate for fractional shares of BANC ONE Common will be issued 
         by BANC ONE in connection with the exchange contemplated by the 
         Merger, but in lieu thereof, any holder of MID STATES Common shall, 
         upon surrender of the certificate or certificates representing such 
         MID STATES Common, be paid cash, without interest, by BANC ONE for 
         such fractional shares on the basis of the BANC ONE Average Price (as 
         hereinafter defined).  The BANC ONE Average Price shall mean the 
         average of the closing prices of BANC ONE Common on the New York Stock 
         Exchange ("NYSE") during the Valuation Period (as hereinafter defined) 
         in The Wall Street Journal for NYSE Composite Transactions.  The term 
         "Valuation Period" shall mean the ten consecutive NYSE trading days 
         ending on the sixth NYSE trading day immediately prior to the proposed 
         Effective Time, as designated by BANC ONE.

    (d)  If prior to the Effective Time, (i) MID STATES shall declare a stock 
         dividend or distribution upon or subdivide, split up, reclassify or 
         combine MID STATES Common or declare a dividend or make a distribution 
         on MID STATES Common in any security convertible into MID STATES 
         Common, or (ii) BANC ONE shall declare a stock dividend or 
         distribution upon or subdivide, split up, reclassify or combine BANC 
         ONE Common or declare a dividend or make a distribution on BANC ONE 
         Common in any security convertible into BANC ONE Common, appropriate 
         adjustment or adjustments will be made in the Exchange Rate.

3.  Dissenting Shares.  MID STATES' shareholders who do not vote their shares 
    of MID STATES Common in favor of the Merger and otherwise perfect 
    applicable dissenters' rights and shareholders of MID STATES Preferred who 
    perfect applicable dissenters' rights will be entitled to dissenters or 
    appraisal rights pursuant to applicable provisions of the Delaware General 
    Corporation Laws.

4.  Surrender of Certificates.

    (a)  Prior to the Effective Time, BANC ONE shall appoint BANK ONE, 
         INDIANAPOLIS, N.A. to act as exchange agent in respect of the Merger 
         (said bank, in its capacity as such exchange agent, being hereinafter 
         called the "Exchange Agent").

    (b)  Promptly following the Effective Time, BANC ONE shall provide to 
         Exchange Agent shares of BANC ONE Common and funds necessary to pay 
         for the shares of MID STATES Common pursuant to Section 2.

    (c)  As soon as practicable after the Effective Time, and subject to the 
         provisions of Section 2 relating to fractional shares, BANC ONE, or 
         BANK ONE, INDIANAPOLIS, N.A., as Exchange Agent for BANC ONE, will 
         distribute to the former holders of MID STATES Common, in exchange for 
         and upon surrender for cancellation by such holders of a certificate 
         or certificates formerly representing shares of MID STATES Common, the 
         certificate(s) for shares of BANC ONE Common in accordance with the 
         Common Exchange Rate.  Each certificate formerly representing MID 
         STATES Common (other than certificates representing shares of MID 
         STATES Common subject to the rights of dissenting shareholders) shall 
         be deemed for all purposes to evidence the ownership of the number of 
         shares of BANC ONE Common and cash for fractional shares into which 
         such shares have been converted, except, however, and notwithstanding 
         the foregoing, that, until such surrender of the certificate or 
         certificates formerly representing shares of MID STATES Common, the 
         holder thereof shall not be entitled to receive any dividend or other 
         payment or distribution payable to holders of BANC ONE Common.  Upon 
         such surrender (or in lieu of surrender other provisions reasonably 
         satisfactory to BANC ONE as are made as set forth in the next 
         following paragraph), there shall be paid to the person entitled 
         thereto the aggregate amount of dividends or other payments or 
         distributions (in each case without interest) which became payable 
         after the Effective Time on the whole shares of BANC ONE Common 
         represented by the certificates issued upon such surrender and 
         exchange or in accordance with such other provisions, as the case may 
         be.  After the Effective Time, the holders of certificates formerly 
         representing shares of MID STATES Common shall cease to have rights 
         with respect to such shares (except such rights, if any, as they may 
         have as dissenting shareholders), and except as aforesaid, their sole 
         rights shall be to exchange said certificates for shares of BANC ONE 
         Common and cash for fractional shares in accordance with this Merger 
         Agreement.

         Certificates representing shares of MID STATES Common surrendered for 
         cancellation by each shareholder entitled to exchange shares of MID 
         STATES Common for shares of BANC ONE Common by reason of the Merger 
         shall be appropriately endorsed or accompanied by such appropriate 
         instruments of transfer as BANC ONE may reasonably require; provided, 
         however, that if there be delivered to BANC ONE by any person who is 
         unable to produce any such certificate formerly representing shares of 
         MID STATES Common for transfer (i) evidence to the reasonable 
         satisfaction of BANC ONE that any such certificate has been lost, 
         wrongfully taken or destroyed, (ii) such security or indemnity as 
         reasonably may be requested by BANC ONE to save it harmless, and (iii) 
         evidence to the reasonable satisfaction of BANC ONE that such person 
         is the owner of the shares theretofore represented by each certificate 
         claimed by him or her to be lost, wrongfully taken or destroyed and 
         that he or she is the person who would be entitled to present each 
         such certificate and to receive shares of BANC ONE Common pursuant to 
         this Merger Agreement, then BANC ONE, in the absence of actual notice 
         to it that any shares theretofore represented by any such certificate 
         have been acquired by a bona fide purchaser, shall deliver to such 
         person the certificate(s) representing shares of BANC ONE Common which 
         such person would have been entitled to receive upon surrender of each 
         such lost, wrongfully taken or destroyed certificate of MID STATES 
         Common.

merger (the "Merger") of MID STATES BANCSHARES, INC. ("MID STATES") and BANC 
ONE ILLINOIS CORPORATION, a subsidiary of BANC ONE, pursuant to the terms of a 
certain Agreement and Plan of Merger dated                   , 1993, (the 
"Merger Agreement"), and in view of the fact that the undersigned has, pursuant 
to the Merger Agreement, been identified as a possible "affiliate" of MID 
STATES within the meaning of Rules 144 and 145 ("Rule 144" and "Rule 145," 
respectively), as amended, of the General Rules and Regulations under the 
Securities Act of 1933, as amended (the "1933 Act"), the undersigned (the 
"Affiliate") represents and undertakes as follows:

The Affiliate shall not offer, sell or otherwise dispose of or transfer any of 
the shares of the Common Stock of BANC ONE to be received by him upon 
consummation of the Merger (the "Shares"), except the Affiliate may offer, sell 
or transfer the Shares (1) in a manner and to the extent permitted by the 
applicable provisions of Rule 145, (2) pursuant to an effective registration 
statement relating to the Shares under the 1933 Act, or (3) in a transaction 
which, in the opinion of counsel for the Affiliate or as described in a 
"no-action" or interpretive letter from the staff of the Securities and 
Exchange Commission, in each case reasonably satisfactory in form and substance 
to BANC ONE, is exempt from the registration requirements of the 1933 Act.

BANC ONE's transfer agents may be given appropriate instructions prohibiting 
transfer of the Shares unless these provisions are complied with and the 
certificate(s) for the Shares may bear a restrictive legend in substantially 
the following form:

    The shares represented by this certificate have been issued to the 
    registered holder as a result of a transaction to which Rule 145 under the 
    Securities Act of 1933, as amended (the "1933 Act") applies.  The shares 
    represented by this certificate may not be sold, transferred or assigned, 
    and the issuer shall not be required to give effect to any attempted sale, 
    transfer or assignment, except pursuant to (i) a registration statement 
    then in effect under the 1933 Act, (ii) a transaction permitted by Rule 145 
    as to which the issuer has received evidence of compliance with the 
    provisions of said Rule 145 reasonably satisfactory to it or (iii) a 
    transaction which, in the opinion of counsel for the Affiliate or as 
    described in a 'no action' or interpretive letter from the staff of the 
    Securities and Exchange Commission, in each case reasonably satisfactory in 
    form and substance to the issuer, is exempt from the registration 
    requirements of the 1933 Act.  The restrictions of this paragraph shall 
    become null and void and this paragraph shall have no effect on and after 
                   .

The undersigned undertakes to take such action as shall be necessary to cause 
the Shares to be received by the undersigned to be registered in a manner that 
will allow for the placement of a restrictive legend on the certificate(s) 
representing such Shares.

The undersigned further undertakes that, if it is necessary in order to 
preserve pooling-of-interests accounting treatment, none of the Shares to be 
received by the undersigned, directly or indirectly, will be sold or otherwise 
disposed of during a period of time beginning with the effective date of the 
Merger and ending with a date upon which financial results of at least 30 days 
of post-merger combined operations have been first published by BANC ONE in 
accordance with SEC Accounting Series Release No. 130 as amended by Release No. 
135, provided that BANC ONE hereby agrees that such financial results will be 
published not later than four months from the Merger.

I hereby acknowledge that pursuant to the provisions of Rules 144 and 145 
certain other persons or entities related to me are, or may be, subject to the 
foregoing restrictions on the resale of BANC ONE Common Stock received by them 
pursuant to the Merger, which persons include (i) any of my relatives or my 
spouse, or any relative of my spouse, who has the same home as me; (ii) any 
trust or estate in which I or any of the persons specified in the preceding 
clause collectively own ten percent (10%) or more of the total beneficial 
interest, or of which I or any of such persons serve as trustee, executor, or 
in any similar capacity; and (iii) any corporation or other organization (other 
than BANC ONE) in which I or any of the persons specified above are the 
beneficial owners, collectively, of ten percent (10%) or more of the equity 
interest therein.  I hereby further acknowledge that I have advised any and all 
of such persons that they are, or may be, subject to the provisions of said 
Rules 144 and 145, and I hereby represent that I will use my best efforts to 
ensure that such persons comply with the provisions of this letter and Rules 
144 and 145, as applicable, upon the resale of any Common Stock of BANC ONE.

IN WITNESS WHEREOF, the Affiliate has made this undertaking as of the day and 
year first above written.

Mid States Bancshares, Inc.
506 15th Street
Molene, Illinois  61265-2184

Attention:  Chairman


Gentlemen:

I am counsel for BANC ONE CORPORATION, an Ohio corporation and a registered 
bank holding company ("BANC ONE") and BANC ONE ILLINOIS CORPORATION ("BANC ONE 
ILLINOIS"), an Illinois corporation, a registered bank holding company and 
wholly owned subsidiary of BANC ONE, and have acted as counsel for BANC ONE and 
BANC ONE ILLINOIS in connection with the merger (the "Merger") of MID STATES 
BANCSHARES, INC. ("MID STATES") and BANC ONE ILLINOIS pursuant to which each of 
the issued and outstanding shares of MID STATES Common will be converted into 
shares of BANC ONE Common.  Such Merger is to be consummated pursuant to the 
terms of an Agreement and Plan of Merger dated              , 1993 ("Merger 
Agreement") between MID STATES, BANC ONE ILLINOIS and joined in by BANC ONE.  
This opinion is furnished to you pursuant to Section 19(c) of the Merger 
Agreement.

Except as otherwise indicated herein, capitalized terms used in this Opinion 
Letter are defined in the Merger Agreement or the Legal Opinion Accord (the 
"Accord") of the ABA Section of Business Law (1991), respectively.  In the 
event of any inconsistency between the definition of any such term in the 
Merger Agreement and the Accord, the definition set forth in the Accord shall 
govern.

This Opinion Letter is governed by, and is to be interpreted in accordance 
with, the Accord.  As a consequence, it is subject to a number of 
qualifications, exceptions, definitions, limitations on coverage, and other 
limitations, all as more particularly described in the Accord, and this Opinion 
Letter should be read in conjunction therewith.

The law covered by the opinions expressed herein is limited solely to the laws 
of the State of Ohio, except as it relates to the status of BANC ONE ILLINOIS 
under Illinoislaw, and the Federal Law of the United States generally.

Based upon and subject to the foregoing, I am of the opinion that:

1.  The Merger Agreement is enforceable against BANC ONE.

2.  The Merger Agreement is enforceable against BANC ONE ILLINOIS.

3.  Except as set forth in the BANC ONE Disclosure Letter, the execution and 
    delivery by BANC ONE and BANC ONE ILLINOIS of, and the performance by BANC 
    ONE and BANC ONE ILLINOIS of their agreements in, the Merger Agreement do 
    not (a) violate the Constituent Documents of BANC ONE and BANC ONE 
    ILLINOIS; (b) violate applicable provisions of statutory law or regulation; 
    (c) breach or otherwise violate any existing obligation of BANC ONE and 
    BANC ONE ILLINOIS under any Court Orders of which I am aware; or (d) 
    breach, or result in a default under, any obligation of BANC ONE or BANC 
    ONE ILLINOIS under an Other Agreement of which I am aware.


I hereby confirm to you, pursuant to the requirements of Section 13(e) of the 
Merger Agreement, that there are no actions or proceedings against BANC ONE or 
any of its subsidiaries, pending or overtly threatened in writing, before any 
court, governmental agency or arbitrator which (i) seek to affect the 
enforceability of the Merger Agreement or (ii) come within the objective 
standard established in the Merger Agreement for disclosure, except as set 
forth in the BANC ONE Disclosure Letter.

I have participated in the preparation of the Registration Statement on Form 
S-4 or other appropriate registration statement form (No.             ) of BANC 
ONE ("Registration Statement"), and in rendering this opinion have limited my 
review of the facts concerning the Registration Statement to discussions with 
and inquiry of Directors, officers and employees of BANC ONE, and Coopers & 
Lybrand, the independent accountants who examined certain of the financial 
statements of BANC ONE included in the Registration Statement, and based 
thereon and subject to the General Qualifications, I am of the opinion that 
such Registration Statement, and the Prospectus included in the Registration 
Statement (except as to financial statements, other financial data and any 
information concerning MID STATES included therein, as to which I express no 
opinion) at the time the Registration Statement became effective under the 
Securities Act of 1933 (the "1933 Act") complied as to form in all material 
respects with the 1933 Act and the rules and regulations of the Securities and 
Exchange Commission thereunder.

I confirm that the Registration Statement has become effective under the 1933 
Act, and to the best of my Actual Knowledge, no stop order suspending the 
effectiveness of the Registration Statement has been issued and no proceedings 
for that purpose have been instituted or are pending or contemplated under the 
1933 Act.

I have not checked the accuracy or completeness of, or otherwise verified, any 
statement of fact contained in the Registration Statement and Prospectus.  
Based on the participations, discussions and inquiries described above, 
however, I have no reason to believe that the Registration Statement (except as 
to financial statements, other financial data and any information concerning 
MID STATES included therein, as to which no view is expressed) at the time it 
became effective and as of the date of this letter contained any untrue 
statement of a material fact or omitted to state a material fact required to be 
stated therein or necessary in order to make the statements therein not 
misleading, or that the Prospectus (except as to financial statements, other 
financial data and any information concerning MID STATES included therein, as 
to which no view is expressed) at such times contained any untrue statement of 
a material fact or omitted to state a material fact necessary in order to make 
the statements therein, in the light of the circumstances under which they were 
made, not misleading or that since the effective date of the Registration 
Statement, any event has occurred which should have been set forth in an 
amendment or supplement to the Registration Statement or the Prospectus which 
has not been set forth in such an amendment or supplement.

The General Qualifications apply to all of the opinions set forth above.

I am rendering this opinion solely for the benefit of MID STATES in connection 
with the transactions described in the Merger Agreement.  It may not be relied 
upon by any other person or for any other person.

Very truly yours,

resolicitation of the MID STATES' shareholders regarding the Merger, during 
which resolicitation the Board of Directors of MID STATES will inform the

           expenses to be assumed and paid by BANC ONE shall include (i) all 
           legal and other expenses and taxes incurred by BANC ONE incident to 
           the consummation of the Merger contemplated by this Merger 
           Agreement, (ii) all legal and other expenses incurred by BANC ONE

           all legal and other expenses, if any, incurred in connection with

           expenses assumed and paid by BANC ONE and/or BANC ONE ILLINOIS 
           pursuant to this Section 10(e), whether directly or indirectly 
           incurred, shall not reduce or otherwise effect the Exchange Rate.

   E.  Subsection (x) of Section 15(h) of the Merger Agreement is amended to 
       read in its entirety as follows:

           (x) entered into any other material transaction (other than in the 
           ordinary course of business) except as expressly contemplated by 
           this Merger Agreement and including a contract with TCC regarding 
           the issuance of the TCC Fairness Opinion.

   F.  Section 15(l) of the Merger Agreement is amended to read in its entirety

           MID STATES has not incurred and will not incur any liability for 
           brokerage, finders', agents', or investment bankers' fees or 
           commissions in connection with this Merger Agreement or the 
           transactions contemplated hereby except for fees to DLJ to be 
           determined in accordance with the terms of that certain engagement 
           letter dated November 6, 1992 annexed as an exhibit to the MID 
           STATES Disclosure Letter and any fees to DLJ and TCC after January 
           25, 1994 for the issuance of a second DLJ Fairness Opinion and a TCC 
           Fairness Opinion.

   G.  Section 19(f) of the Merger Agreement is amended to read in its entirety 
       as follows:

           MID STATES shall have received opinions from DLJ and TCC dated as of 
           a date not later than the date of the Second Proxy Statement, to the 
           effect that, in the opinion of such firms, the financial 
           consideration to be received as a result of the Merger is fair from 
           a financial point of view to the holders of MID STATES Common and 
           such opinions shall not have been withdrawn prior to the Effective 
           Time.

   H.  Section 20(b) of the Merger Agreement is amended to read in its entirety 
       as follows:

           The registration statement, including any post-effective amendment 
           required to be filed by BANC ONE pursuant to Section 10(d) of this 
           Merger Agreement, shall have become effective by an order of the 
           SEC, the shares of BANC ONE Common to be exchanged in the Merger 
           shall have been qualified or exempted under all applicable state 
           securities laws, and there shall have been no stop order issued or 
           threatened by the SEC that suspends or would suspend the 
           effectiveness of the registration statement, and no proceeding by 
           the SEC shall have been commenced, pending or overtly threatened for 
           such purpose and the BANC ONE Common to be issued in the Merger will 
           be authorized for trading on the NYSE.

   I.  The first paragraph of Section 25(e) of the Merger Agreement is amended 
       to read in its entirety as follows:

           MID STATES, by action of its Board of Directors, may elect to 
           terminate this Merger Agreement, whether before or after approval of 
           the Merger by the shareholders of MID STATES, by giving three (3) 
           days written notice of such election to BANC ONE at any time after 
           the date of this Amendment.  Such election shall be based on the MID 
           STATES' Board of Directors conclusion that the termination of the 
           Merger is in the best interests of MID STATES because of (a) an 
           inability to obtain fairness opinions or any other cause that 
           precludes the timely holding of the MID STATES' shareholders' 
           meeting necessary to approve the Merger or (b) the reasonable 
           probability that any other condition to MID STATES' obligation to 
           consummate the Merger cannot be timely satisfied.

   J.  The last sentence of Section 25(g) of the Merger Agreement is amended to 
       read in its entirety as follows:

           If the Merger is not consummated as the result of termination of

  Re:    BANC ONE CORPORATION Registration Statement on Form S-4 (Mid States 
         Bancshares, Inc.) -- Registration No. 33-51219                        


Gentlemen:

I have acted as counsel to BANC ONE CORPORATION ("BANC ONE") in connection with 
the Registration Statement on Form S-4 to be filed by BANC ONE with the 
Securities and Exchange Commission under the Securities Act of 1933, as 
amended.  The Registration Statement relates to the issuance of up to 908,822 
shares of common stock, no par value, of BANC ONE (the "Shares") to the 
shareholders of Mid States Bancshares, Inc. ("MID STATES") in connection with 
the merger (the "Merger") of MID STATES with and into Banc One Illinois 
Corporation ("Bank One Illinois"), a wholly owned subsidiary of BANC ONE, 
pursuant to the terms of a Merger Agreement dated May 25, 1993, as amended on 
February 22, 1994 and March 25, 1994, by and among MID STATES, BANC ONE and 
Banc One Illinois (the "Merger Agreement").

In this connection, I have examined such corporate records and other documents 
and certificates of public officials as I have deemed necessary in order to 
render the opinion set forth below.

Based upon the foregoing, it is my opinion that upon the satisfaction of 
certain conditions provided for in the Merger Agreement, the Shares, when 
issued and delivered pursuant to the provisions of the Merger Agreement and 
upon consummation of the Merger, will be validly issued, fully paid and 
non-assessable.

I hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement.


Very truly yours,

Board of Directors
BANC ONE CORPORATION

Columbus, Ohio  43271

Gentlemen:

In connection with the solicitation of proxies for a special meeting of 
shareholders of Mid States Bancshares, Inc., a Delaware corporation ("Mid 
States"), at which there will be presented a proposed merger ("Merger") 
of Mid States into Banc One Illinois Corporation,
an Illinois corporation ("BOIC") and wholly-owned subsidiary of BANC ONE
CORPORATION, an Ohio Corporation ("Banc One"), you have requested our opinion 
with respect to certain federal income tax consequences of the Merger.  
The Merger contemplates the acquisition by BOIC of all the assets and 
liabilities of Mid States in exchange for common stock, with no par 
value, of Banc One ("Banc One Common") pursuant to an Agreement and Plan 
of Merger, dated as of May 25, 1993, as amended February 22, 1994
and March 28, 1994, entered into by Mid States, BOIC and Banc One 
(the "Merger Agreement").

The opinions expressed in this letter are based on the Internal Revenue Code 
of 1986, as amended (the "Code"), the Income Tax Regulations promulgated by the 
Treasury Department thereunder and judicial authority reported as of the date 
hereof.  We have also considered the position of the Internal Revenue Service 
(the "Service") reflected in published and private rulings.  Although we 
are not aware of any pending changes to these authorities
that would alter our opinions, there can be no assurance that future 
legislative or administrative changes, court decisions or Service 
interpretations will not significantly modify the statements or opinions 
expressed herein.

We express no opinion herein as to any issue of federal law other than those
specifically considered herein.  We also do not express any opinion as to any 
issue of state or local law.

For the purposes indicated above, and based upon our review, the conditions 
set forth below, and the anticipated receipt by us prior to closing of such 
representations as we may request of Mid States, certain shareholders of 
Mid States, and Banc One, in such form as we may request, it is our opinion 
that:

(1)  The merger of Mid States into BOIC, pursuant to the Merger Agreement, will
     constitute a reorganization within the meaning of section 368(a)(1)(A) and
     section 368(a)(2)(D) of the Code.  Mid States, BOIC and Banc One will each
     be considered "a party to a reorganization" within the meaning of section
     368(b) of the Code for purposes of this reorganization;

(2)  No gain or loss will be recognized by Mid States upon the transfer of 
     its assets and liabilities to BOIC pursuant to the Merger;

(3)  No gain or loss will be recognized by BOIC upon the receipt of the 
     assets and liabilities of Mid States pursuant to the Merger;

(4)  The tax basis of the assets of Mid States in the hands of BOIC will be the
     same as the tax basis of such assets in the hands of Mid States immediately
     prior to the transfer;

(5)  The holding period of the assets of Mid States transferred to BOIC will 
     include the period during which such assets were held by Mid States 
     prior to the transfer;

(6)  No gain or loss will be recognized by the shareholders of Mid States 
     upon the receipt of Banc One Common in exchange for their shares of Mid 
     States (disregarding for this purpose any cash received upon 
     exercise of dissenters' rights or in lieu of the receipt of fractional 
     shares);

(7)  The tax basis of the Banc One Common (including for this purpose any
     fractional share interests which shareholders of Mid States will be 
     deemed to receive and then sell in exchange for cash) 
     received by the shareholders of
     Mid States will be the same as the tax basis of the Mid States shares
     exchanged therefor; and

(8)  The holding period of the Banc One Common received by the shareholders of
     Mid States will include the holding period of the Mid States shares 
     exchanged therefor, provided that at the time of the exchange 
     the Mid States shares were held as capital assets.

In rendering this opinion, we have examined the Merger Agreement and such other
documents as we have deemed necessary or appropriate.  We have assumed the 
genuineness of all signatures, the legal capacity of all natural persons, the 
authenticity of all documents submitted to us as originals, the conformity to 
original documents of all documents submitted to us as copies, the authenticity 
of the originals of such copies, and that the Merger will be
consummated pursuant to Illinois and Delaware law in the manner set forth in 
the Merger Agreement.  We have also assumed that any written representations 
and covenants of Mid States, certain shareholders of Mid States, and 
Banc One as we may request in connection with rendering our opinion will be 
provided to us by such parties prior to the closing and that such 
representations and covenants will be accurate and complete in all respects 
as of the time they are provided to us and as of the closing.  Any changes 
in these facts, or in the accuracy of these assumptions, representations 
or covenants, may necessitate reconsideration of our opinion and possibly 
result in different conclusions.

Our opinion is limited to those federal income 
tax issues specifically considered herein
and is addressed to and is only for the 
benefit of Mid States and Banc One. The opinion is
furnished to you pursuant to section 12 of the 
Merger Agreement and may not be used or
relied upon for any other purpose and may 
not be circulated or otherwise referred to for any
other purpose without our express written consent.  
Although the discussion herein is based
upon our best interpretation of existing 
sources of law and expresses what we believe a court
would properly conclude if presented with these 
issues, no assurance can be given that such
interpretations would be followed if they were 
to become the subject of judicial or
administrative proceedings.

We hereby consent to the filing of this opinion as an Exhibit to the 
Post-effective Amendment No. 1 to the Registration Statement and to the 
use of our name in the Prospectus and Proxy Statement constituting part of 
the Registration Statement.  In giving such consent, we do not thereby 
concede that we are within the category of persons whose consent is
required under section 7 of the Securities Act of 1933, as amended, 
or the rules and regulations of the Securities and Exchange Commission 
thereunder.

                              Very truly yours,


                              VEDDER, PRICE, KAUFMAN & KAMMHOLZ
