                                     SHARES

     1. REGISTRATION AND TRANSFER OF CERTIFICATES. Each shareholder of the
Corporation whose shares have been fully paid for shall be entitled to a
certificate or certificates showing the number of shares registered in his name
on the books of the Corporation. Each certificate shall be signed by the
Chairman of the Board or the President or Vice-President of the Corporation and
the Secretary or Assistant Secretary or the Treasurer or an Assistant Treasurer.
Shares shall be transferred only on the books of the Corporation by the holder
thereof, in person or by Attorney, upon surrender and cancellation of
certificates for a like number of shares.

     2. SUBSTITUTED CERTIFICATES. The Board of Directors may authorize the
issuance of a new certificate in place of any certificate theretofore issued by
the Corporation alleged to have been lost or destroyed; in its discretion
requiring the owner of the lost or destroyed certificate, or the legal
representative, to give the Corporation a bond in such sum as the Board of
Directors may direct as indemnity against any claim that may be made against the
Corporation; or, if in the judgment of the Board it is proper to do so, a new
certificate may be issued without requiring any bond.

     3. SHAREHOLDERS ENTITLED TO NOTICE AND TO VOTE. The Board of Directors may
fix a time not exceeding forty-five (45) days preceding the date of any meeting
of shareholders, or any dividend payment date, or any date for the allotment of
rights, as a record date for the determination of the shareholders entitled to
notice of such meeting, or to vote thereat, or to receive such dividends or
rights, as the case may be, or in lieu thereof, the Board of Directors may close
the books of the Corporation against the transfer of shares during the whole or
any part of such period.

     1. ANNUAL MEETING. The Annual Meeting of shareholders shall be held at such
date, time and place as may be designated from time to time by the Board of
Directors, for the election of Directors and the consideration of reports to be
laid before the meeting. Upon due notice there may also be considered and acted
upon at the Annual Meeting any matter which can properly be considered and acted
upon at a

   2

special meeting, in which case and for which purpose the Annual Meeting shall
also be considered as, and shall be, a special meeting. When an Annual Meeting
is not held or Directors are not elected thereat, they may be elected at a
special meeting called for that purpose.

     2. SPECIAL MEETINGS. Special meetings of the shareholders may be called by
the President, or an Executive or Senior Vice-President, or the Chairman of the
Board of Directors, or by the Executive Committee, or by a majority of the Board
of Directors, acting with or without a meeting, or by persons who hold
twenty-five percent of all the shares outstanding and entitled to vote thereat,
at such place or places as may be designated in the call therefore, and notice
thereof; provided, however, that a meeting for the election of Directors may be
held only within the State of Ohio.

     3. NOTICE OF MEETINGS. Notice of meetings of shareholders shall be given by
the Secretary, or in his absence by the Chairman of the Board or President or a
Vice-President, and such notice shall state the purpose or purposes for which
the meeting is called, and the time and place where it is to be held, and shall
be given to each shareholder of record entitled to vote at such meeting or
entitled to notice thereof, at least ten (10) days prior to the meeting. Notice
may be given to the shareholder at his address as it appears upon the records of
the Corporation. In the event of the transfer of shares after notice has been
given and prior to the holding of the meeting, it shall not be necessary to
serve notice upon the transferee. Notice of the time, place and purpose of any
meeting of shareholders may be waived by the assent of every shareholder
entitled to notice, filed with or entered upon the records of the meeting,
either before or after the holding thereof.

     4. QUORUM. The holders of a majority of the shares issued and outstanding,
entitled to vote, present either in person or by proxy, shall constitute a
quorum, unless a larger number is required by the laws of Ohio, in which case
the number required by the laws of Ohio, present either in person or by proxy,
shall constitute a quorum, but any less number may adjourn the meeting from time
to time, until a quorum is obtained, and no further notice of such adjourned
meeting need be given other than by announcement at the meeting at which such
adjournment is taken.

     5. PROXIES. Each shareholder entitled to vote shall be entitled to one
vote, either in person or by proxy, for each share of the Corporation standing
in his name at the time of the closing of the books for such meeting. No proxy
shall be valid after the expiration of eleven (11) months from the date thereof,
unless a longer time be specified therein.

                               BOARD OF DIRECTORS

     1. NUMBER AND ELECTION. The powers and authority of the Corporation shall
be exercised and its business managed and controlled by a Board of Directors.
The election of Directors shall be by ballot and shall be held at the Annual
Meeting of shareholders or at a special meeting called for that purpose. The
maximum number of the Directors of the Corporation shall be eighteen. Subject to
such maximum, the number of Directors may be fixed or changed (a) at a meeting
of the shareholders called for the purpose of electing Directors at which a
quorum is present, by the affirmative vote of the holders of a majority of the
shares that are represented at the meeting and entitled to vote on the proposal,
and (b) by the Directors, by the vote of a majority of their number, who may
also fill any Director's office that is created by an increase in the number of
Directors. The Directors shall be divided into three classes, as nearly equal in
number as possible, as determined by the Board of Directors of the Corporation.
A separate election shall be held for each class of Directors as hereinafter
provided. Directors elected at the first election for the first class shall hold
office for the term of one year from the date of their election and until the
election of their successors. Directors elected at the first election for the
second class shall hold office for the term of two years from the date of their
election and until the election of their successors, and Directors elected at
the first election for the third class shall hold office for the term of three
years from the date of their election and until the election of their
successors. At each annual election, the successors to the Directors of each
class whose terms shall expire in that year shall be elected to hold office for
the term of three years from the date of their election and until the election
of their successors. In case of any increase in the number of Directors of any
class, any additional Directors elected to such class shall hold office for a
term which shall coincide with the term of such class.

     2. VACANCY AND REMOVAL. All Directors, for whatever terms elected, shall
hold office subject to applicable statutory provisions as to the creation of
vacancies and removal; provided, however, that all Directors, all the Directors
of a particular class or any individual Director may be removed from office,
without assigning any cause, only by the affirmative vote of the holders of at
least two-thirds of the voting power of the outstanding shares of stock entitled
to vote generally on the election of Directors.

     3. RESIGNATION. Any Director may resign at any time. Such resignation shall
be made in writing and shall take effect at the time specified therein. If no
time is specified, it shall become effective from the time of its receipt by the
Corporation, and the Secretary shall record such resignation, noting the day,
hour and minute of its reception. The acceptance of a resignation shall not be
necessary to make it effective.

     4. MEETINGS. Directors may meet at such times and at such places within or
without the State of Ohio as they may determine. Special meetings of the Board
of Directors may be called by the Chairman of the Board of Directors or the
President on

                                      -3-
   4

one day's notice to each Director by whom such notice is not waived, given
either personally or by mail, telephone, telegram, telex, facsimile or similar
medium of communication, and will be called by the Chairman of the Board of
Directors or the President, in like manner and on like notice, on the written
request of not less than one-third of the Board of Directors. A majority of the
Board of Directors shall be necessary to constitute a quorum for the transaction
of business, and the act of a majority of Directors present at a meeting at
which a quorum is present shall be the act of the Board of Directors.

     5. BY-LAWS. The Board of Directors may adopt By-Laws for its own government
not inconsistent with the Articles of Incorporation or Regulations of the
Corporation.


                                   ARTICLE IV
                          INDEMNIFICATION AND INSURANCE

     1. INDEMNIFICATION. (a) The Corporation shall indemnify any person who was
or is a party or is threatened to be made a party, to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a Director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a Director, trustee, officer, employee or agent of another
corporation, domestic or foreign, nonprofit or for profit, partnership, joint
venture, trust or other enterprise, to the full extent permitted from time to
time under the laws of the State of Ohio; provided, however, that the
Corporation shall indemnify any such agent (as opposed to any Director, officer
or employee) of the Corporation to an extent greater than that required by law
only if and to the extent that the Directors, may, in their discretion, so
determine.

     (b) The indemnification authorized by this Article shall not be exclusive
of, and shall be in addition to, any other rights granted to those seeking
indemnification hereunder or under the Articles or any agreement, vote of
shareholders or disinterested Directors, or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a Director,
trustee, officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

     (c) No amendment, termination or repeal of this Article IV shall affect or
impair in any way the rights of any Director or officer of the Corporation to
indemnification under the provisions hereof with respect to any action, suit or
proceeding arising out of, or relating to, any actions, transactions or facts
occurring prior to the final adoption of such amendment, termination or repeal.

     2. LIABILITY INSURANCE. The Corporation may purchase and maintain insurance
or furnish similar protection, including but not limited to trust funds, letters
of

                                      -4-

credit or self-insurance, on behalf of or for any person who is or was a
Director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a Director, trustee, officer, employee or
agent of another corporation, domestic or foreign, nonprofit or for profit,
partnership, joint venture, trust or other enterprise, against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under this Article. Insurance may be
purchased from or maintained with a person in which the Corporation has a
financial interest.


                                    ARTICLE V
                        NOMINATION OF DIRECTOR CANDIDATES

     1. NOTIFICATION OF NOMINEES. Nominations for the election of Directors may
be made by the Board of Directors or a committee appointed by the Board of
Directors or by any shareholder entitled to vote in the election of Directors
generally. However, any shareholder entitled to vote in the election of
Directors generally may nominate one or more persons for election as Directors
at a meeting only if written notice of such shareholder's intent to make such
nomination or nominations has been received by the Secretary of the Corporation
not less than 80 days in advance of such meeting; provided, however, that in the
event that the date of the meeting was not publicly announced by the Corporation
by mail, press release or otherwise more than 90 days prior to the meeting,
notice by the shareholder to be timely must be delivered to the Secretary of the
Corporation not later than the close of business on the tenth day following the
day on which such announcement of the date of the meeting was communicated to
shareholders. Each such notice shall set forth: (a) the name and address of the
shareholder who intends to make the nomination and of the person or persons to
be nominated; (b) a representation that the shareholder is a holder of record of
stock of the Corporation entitled to vote for the election of Directors on the
date of such notice and intends to appear in person or by proxy at the meeting
to nominate the person or persons specified in the notice; (c) a description of
all arrangements or understandings between the shareholder and each nominee and
any other person or persons (naming such person or persons) pursuant to which
the nomination or nominations are to be made by the shareholder; (d) such other
information regarding each nominee proposed by such shareholder as would be
required to be included in a proxy statement filed pursuant to the proxy rules
of the Securities and Exchange Commission, had the nominee been nominated, or
intended to be nominated, by the Board of Directors; and (e) the consent of each
nominee to serve as a Director of the Corporation if so elected.

     2. SUBSTITUTION OF NOMINEES. In the event that a person is validly
designated as a nominee in accordance with paragraph 1 above, and shall
thereafter become unable or unwilling to stand for election to the Board of
Directors, the Board of Directors or the shareholder who proposed such nominee,
as the case may be, may

                                      -5-

designate a substitute nominee upon delivery, not fewer than five days prior to
the date of the meeting for the election of such nominee of a written notice to
the Secretary setting forth such information regarding such substitute nominee
as would have been required to be delivered to the Secretary pursuant to
paragraph 1 above had such substitute nominee been initially proposed as a
nominee. Such notice shall include a signed consent to serve as a Director of
the Corporation, if elected, of each such substitute nominee.

     3. COMPLIANCE WITH PROCEDURES. If the chairman of the meeting for the
election of Directors determines that a nomination of any candidate for election
as a Director at such meeting was not made in accordance with the applicable
provisions of paragraphs 1 and 2 above, such nomination shall be void.

among the Board of Directors or in any committee of the Board of Directors.
Committees shall consist of one or more Directors as appointed by the Board of
Directors. The Board of Directors may appoint one or more Directors as alternate
members of any such committee, who may take the place of any absent member or
members at a meeting of such committee. Except as above provided and except to
the extent that its powers are limited by the Directors, the Executive Committee
during the intervals between meetings of the Directors shall possess and may
exercise, subject to the control and direction of the Directors, all of the
powers of the Directors in the management and control of the business of the
Corporation, regardless of whether such powers are specifically conferred by
these Regulations. All action taken by the Executive Committee shall be reported
to the Directors at their first meeting thereafter.

     2. QUORUM AND ACTION. Unless otherwise ordered by the Board of Directors, a
majority of the members of any committee appointed by the Board of Directors
pursuant to this Article VI shall constitute a quorum at any meeting thereof,
and the act of a majority of the members present at a meeting at which a quorum
is present shall be the act of such committee. Action may be taken by any such
committee without a meeting by a writing or writings signed by all of its
members. Any such committee shall prescribe its own rules for calling and
holding meetings and its method of procedure, subject to any rules prescribed by
the Board of Directors, and shall keep a written record of all action taken by
it.
