     FOURTH. The annual meeting of the shareholders for the election of
Directors and the transaction of whatever other business may be brought before
said meeting shall be held at the main office of this Association or such other
place as the Board of Directors may designate, on the day of each year specified

elections shall be held according to such lawful regulations as may be
prescribed by the Board of Directors.

     FIFTH. The authorized amount of capital stock of this Association shall be
2,073,750 shares of common stock of the par value of Ten Dollars ($10) each; but
said capital stock may be increased or decreased from time-to-time, in
accordance with the provisions of the laws of the United States.


         No holder of shares of the capital stock of any class of the
Association shall have the preemptive or preferential right of subscription to
any share of any class of stock of this Association, whether now or hereafter
authorized or to any obligations convertible into stock of this Association,
issued or sold, nor any right of subscription to any thereof other than such, if
any, as the Board of Directors, in its discretion, may from time-to-time
determine and at such price as the Board of Directors may from time-to-time fix.
         This Association, at any time and from time-to-time, may authorize and
issue debt obligations, whether or not subordinated, without the approval of the
shareholders.

     SIXTH. The Board of Directors shall appoint one of its members President of
the Association, who shall be Chairman of the Board, unless the Board appoints
another director to be the Chairman. The Board of Directors shall have the power

Association.


                                       -5-
<PAGE>   6
     The Board of Directors shall have the power to define the duties of the
officers and employees of this Association; to fix the salaries to be paid to
them; to dismiss them; to require bonds from them and to fix the penalty
thereof; to regulate the manner in which any increase of the capital of this
Association shall be made; to manage and administer the business and affairs of

Ohio, without the approval of the shareholders but subject to the approval of
the Comptroller of the Currency; and shall have the power to establish or change
the location of any branch or branches of this Association to any other
location, without the approval of the shareholders but subject to the approval
of the Comptroller of the Currency.

     EIGHTH. The corporate existence of this Association shall continue until
terminated in accordance with the laws of the United States.

     NINTH. The Board of Directors of this Association, or any three or more
shareholders owning, in the aggregate, not less than 10 percent of the stock of
this Association, may call a special meeting of shareholders at any time. Unless
otherwise provided by the laws of the United States, a notice of the time, place

the date of such meeting to each shareholder of record at his address as shown
upon the books of this Association.



                                       -6-
<PAGE>   7
     TENTH. Every person who is or was a Director, officer or employee of the
Association or of any other corporation which he served as a Director, officer
or employee at the request of the Association as part of his regularly assigned
duties may be indemnified by the Association in accordance with the provisions
of this paragraph against all liability (including, without limitation,
judgments, fines, penalties and settlements) and all reasonable expenses
(including, without limitation, attorneys' fees and investigative expenses) that
may be incurred or paid by him in connection with any claim, action, suit or
proceeding, whether civil, criminal or administrative (all referred to hereafter
in this paragraphs as "Claims") or in connection with any appeal relating
thereto in which he may become involved as a party or otherwise or with which he
may be threatened by reason of his being or having been a Director, officer or
employee of the Association or such other corporation, or by reason of any
action taken or omitted by him in his capacity as such Director, officer or
employee, whether or not he continues to be such at the time such liability or
expenses are incurred, provided that nothing contained in this paragraph shall
be construed to permit indemnification of any such person who is adjudged guilty
of, or liable for, willful misconduct, gross neglect of duty or criminal acts,
unless, at the time such indemnification is sought, such indemnification in such
instance is permissible under applicable law and regulations, including
published rulings of the Comptroller of the Currency or other appropriate
supervisory or regulatory authority, and provided further that there shall be no
indemnification of directors, officers, or employees against expenses,
penalties, or other payments incurred in an administrative proceeding or action
instituted by an appropriate regulatory agency which proceeding or action
results in a final order assessing civil money penalties or requiring
affirmative action by an individual or individuals in the form of payments to
the Association. Every person who may be indemnified under the provisions of
this paragraph and who has been wholly successful on the merits with respect to
any Claim shall be entitled to indemnification as of right. Except as provided
in the preceding sentence, any indemnification under this paragraph shall be at
the sole discretion of the Board of Directors and shall be made only if the
Board of Directors or the Executive Committee acting by a quorum consisting of





                                       -7-
<PAGE>   8
Directors who are not parties to such Claim shall find or if independent legal
counsel (who may be the regular counsel of the Association) selected by the
Board of Directors or Executive Committee whether or not a disinterested quorum
exists shall render their opinion that in view of all of the circumstances then
surrounding the Claim, such indemnification is equitable and in the best
interests of the Association. Among the circumstances to be taken into
consideration in arriving at such a finding or opinion is the existence or
non-existence of a contract of insurance or indemnity under which the
Association would be wholly or partially reimbursed for such indemnification,
but the existence or non-existence of such insurance is not the sole
circumstance to be considered nor shall it be wholly determinative of whether
such indemnification shall be made. In addition to such finding or opinion, no
indemnification under this paragraph shall be made unless the Board of Directors
or the Executive Committee acting by a quorum consisting of Directors who are
not parties to such Claim shall find or if independent legal counsel (who may be
the regular counsel of the Association) selected by the Board of Directors or
Executive Committee whether or not a disinterested quorum exists shall render
their opinion that the Director, officer or employee acted in good faith in what
he reasonably believed to be the best interests of the Association or such other
corporation and further in the case of any criminal action or proceeding, that
the Director, officer or employee reasonably believed his conduct to be lawful.
Determination of any Claim by judgment adverse to a Director, officer or
employee by settlement with or without Court approval or conviction upon a plea
of guilty or of nolocontendere or its equivalent shall not create a presumption
that a Director, officer or employee failed to meet the standards of conduct set
forth in this paragraph. Expenses incurred with respect to any Claim may be
advanced by the Association prior to the final disposition thereof upon receipt
of an undertaking satisfactory to the Association by or on behalf of the
recipient to repay such amount unless it is ultimately determined that he is
entitled to indemnification under this paragraph. The rights of indemnification
provided in this paragraph shall be in addition to any rights to which any
Director, officer or employee may otherwise be entitled by contract or as a
matter of law.



                                       -8-
<PAGE>   9
Every person who shall act as a Director, officer or employee of this
Association shall be conclusively presumed to be doing so in reliance upon the
right of indemnification provided for in this paragraph.

     ELEVENTH. These Articles of Association may be amended at any regular or
special meeting of the shareholders by the affirmative vote of the holders of a
majority of the stock of this Association, unless the vote of the holders of a
greater amount of stock is required by law, and in that case by the vote of the
holders of such greater amount.

                             MEETING OF SHAREHOLDERS


SECTION 1.01. ANNUAL MEETING. The regular annual meeting of the Shareholders of
the Bank for the election of Directors and for the transaction of such business
as may properly come before the meeting shall be held at its main banking house,
or other convenient place duly authorized by the Board of Directors, on the
third Monday of January of each year, or on the next succeeding banking day, if
the day fixed falls on a legal holiday. If from any cause, an election of
directors is not made on the day fixed for the regular meeting of shareholders
or, in the event of a legal holiday, on the next succeeding banking day, the
Board of Directors shall order the election to be held on some subsequent day,
as soon thereafter as practicable, according to the provisions of law; and
notice thereof shall be given in the manner herein provided for the annual
meeting. Notice of such annual meeting shall be given by or under the direction
of the Secretary or such other officer as may be designated by the Chief
Executive Officer by first-class mail, postage prepaid, to all shareholders of
record of the Bank at their respective addresses as shown upon the books of the
Bank mailed not less than ten days prior to the date fixed for such meeting.

     SECTION 1.02. SPECIAL MEETINGS. A special meeting of the shareholders of
this Bank may be called at any time by the Board of Directors or by any three or
more shareholders owning, in the aggregate, not less than ten percent of the
stock of this Bank. The notice of any special meeting of the shareholders called

shall be given by or under the direction of the Secretary, or such other officer
as is designated by the Chief Executive Officer, by first-class mail, postage
prepaid, to all shareholders of



                                      -10-
<PAGE>   11
record of the Bank at their respective addresses as shown upon the books of the
Bank, mailed not less than ten days prior to the date fixed for such meeting.

     Any special meeting of shareholders shall be conducted and its proceedings
recorded in the manner prescribed in these By-Laws for annual meetings of
shareholders.

     SECTION 1.03. SECRETARY OF SHAREHOLDERS' MEETING. The Board of Directors
may designate a person to be the Secretary of the meetings of shareholders. In
the absence of a presiding officer, as designated in these By-Laws, the Board of
Directors may designate a person to act as the presiding officer. In the event
the Board of Directors fails to designate a person to preside at a meeting of
shareholders and a Secretary of such meeting, the shareholders present or
represented shall elect a person to reside and a person to serve as Secretary of
the meeting.

     The Secretary of the meetings of shareholders shall cause the returns made
by the judges and election and other proceedings to be recorded in the minute
book of the Bank. The presiding officer shall notify the directors-elect of
their election and to meet forthwith for the organization of the new board.

     The minutes of the meeting shall be signed by the presiding officer and the
Secretary designated for the meeting.

SECTION 1.04. JUDGES OF ELECTION. The Board of Directors may appoint as many as
three shareholders to be judges of the election, who shall hold and conduct the
same, and who shall, after the election has been held, notify, in writing over
their signatures, the secretary of the shareholders' meeting of the result
thereof and the names of the Directors elected; provided, however, that upon
failure for any reason of any judge or judges of election, so appointed by the
directors, to serve, the presiding officer of the meeting shall appoint other
shareholders or their proxies to fill the vacancies. The judges of election at
the request of the chairman of the



                                      -11-
<PAGE>   12
meeting, shall act as tellers of any other vote by ballot taken at such meeting,
and shall notify, in writing over their signatures, the secretary of the Board
of Directors of the result thereof.

SECTION 1.05. PROXIES. In all elections of Directors, each shareholder of
record, who is qualified to vote under the provisions of Federal Law, shall have
the right to vote the number of shares of record in his name for as many persons
as there are Directors to be elected, or to cumulate such shares as provided by
Federal Law. In deciding all other questions at meetings of shareholders, each
shareholder shall be entitled to one vote on each share of stock of record in
his name. Shareholders may vote by proxy duly authorized in writing. All proxies
used at the annual meeting shall be secured for that meeting only, or any
adjournment thereof, and shall be dated, and if not dated by the shareholder,
shall be dated as of the date of receipt thereof. No officer or employee of this
Bank may act as proxy.

SECTION 1.06. QUORUM. Holders of record of a majority of the shares of the
capital stock of the Bank, eligible to be voted, present either in person or by
proxy, shall constitute a quorum for the transaction of business at any meeting
of shareholders, but shareholders present at any meeting and constituting less
than a quorum may, without further notice, adjourn the meeting from time to time
until a quorum is obtained. A majority of the votes cast shall decide every
question or matter submitted to the shareholders at any meeting, unless
otherwise provided by law or by the Articles of Association.

                                   ARTICLE II
                                    DIRECTORS

SECTION 2.01. MANAGEMENT OF THE BANK. The business of the Bank shall be managed
by the Board of Directors. Each director of the Bank shall be the beneficial
owner of a substantial number of shares of BANC ONE CORPORATION and shall be
employed either in the position of Chief Executive Officer or active leadership
within his or her business, professional or community interest which shall be
located within the geographic area in which the Bank operates, or as an
executive officer of the Bank. A director shall not be eligible for nomination
and re-election as a director of the Bank if such person's executive or
leadership position within his or her business, professional or community
interests which qualifies such person as a director of Bank terminates. The age
of 70 is the mandatory retirement age as a director of the Bank. When a person's
eligibility as director of the Bank terminates, whether because of change in
share ownership, position, residency or age, within 30 days after such
termination, such person shall submit his resignation as a director to be
effective at the pleasure of the Board provided, however, that in no event shall
such person be nominated or elected as a director. Provided, however, following
a person's retirement or resignation as a director because of the age
limitations herein set forth with respect to election or re-election as a
director, such person may, in special or unusual circumstances, and at the
discretion of the Board, be elected by the directors as a Director Emeritus of
the Bank for a limited period of time. A Director Emeritus shall have the right
to participate in board meetings but shall be without the power to vote and
shall be subject to re-election by the Board at its organizational meeting
following the Bank's annual meeting of shareholders.

SECTION 2.02. QUALIFICATIONS. Each director shall have the qualification
prescribed by law. No person elected a director may exercise any of the powers
of his office until he has taken the oath of such office.



                                      -13-
<PAGE>   14
SECTION 2.03. TERM OF OFFICE/VACANCIES. A director shall hold office until the
annual meeting for the year in which his term expires and until his successor
shall be elected and shall qualify, subject, however, to his prior death,
resignation, or removal from office. Whenever any vacancy shall occur among the
directors, the remaining directors shall constitute the directors of the Bank
until such vacancy is filled by the remaining directors, and any director so
appointed shall hold office for the unexpired term of his or her successor.
Notwithstanding the foregoing, each director shall hold office and serve at the
pleasure of the Board.

SECTION 2.04. ORGANIZATION MEETING. The directors elected by the shareholders
shall meet for organization of the new board at the time fixed by the presiding
officer of the annual meeting. If at the time fixed for such meeting there is no
quorum present, the Directors in attendance may adjourn from time to time until
a quorum is obtained. A majority of the number of Directors elected by the
shareholders shall constitute a quorum for the transaction of business.


SECTION 2.05. REGULAR MEETINGS. The regular meetings of the Board of Directors
shall be held on the third Monday of each calendar month excluding March and
July, which meeting will be held at 4:00 p.m. When any regular meeting of the
Board falls on a holiday, the meeting shall be held on such other day as the
Board may previously designate or should the Board fail to so designate, on such
day as the Chairman of the Board of President may fix. Whenever a quorum is not
present, the directors in attendance shall adjourn the meeting to a time not
later than the date fixed by the Bylaws for the next succeeding regular meeting
of the Board.

SECTION 2.06. SPECIAL MEETINGS. Special meetings of the Board of Directors shall
be held at the call of the Chairman of the Board or President, or at the request
of two or more Directors. Any special meeting may be held at such place in
Franklin County, Ohio, and at such time as may be fixed in the call. Written or
oral notice shall be given to each Director not later than the day next
preceding the day on which special meeting is to be held, which notice may be
waived in writing.



                                      -14-
<PAGE>   15
The presence of a Director at any meeting of the Board shall be deemed a waiver
of notice thereof by him. Whenever a quorum is not present the Directors in
attendance shall adjourn the special meeting from day to day until a quorum is
obtained.

SECTION 2.07. QUORUM. A majority of the Directors shall constitute a quorum at
any meeting, except when otherwise provided by law; but a lesser number may
adjourn any meeting, from time-to-time, and the meeting may be held, as
adjourned, without further notice. When, however, less than a quorum as herein
defined, but at least one-third and not less than two of the authorized number
of Directors are present at a meeting of the Directors, business of the Bank may
be transacted and matters before the Board approved or disapproved by the
