     SECTION 2.4.  Notice of Meetings.  Unless waived as herein provided,
whenever shareholders are required or permitted to take any action at a meeting,
written notice of the meeting shall be given stating the place, date and hour of
the meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.  Such written notice shall be given not less than
five (5) days nor more than sixty (60) days before the date of the meeting to
each shareholder entitled to vote at the meeting or in the event of a merger,
consolidation, share exchange, dissolution or sale, lease or exchange of all or
substantially all of the Corporation's property, business or assets not less
than ten (10) days before the date of the meeting.  If mailed, notice is given
when deposited in the United States mail, postage prepaid, directed to the
shareholder at the shareholder's address as it appears on the records of the
Corporation.

     When a meeting is adjourned to another time or place in accordance with
Section 2.5 of these Regulations, notice need not be given of the adjourned
meeting if the time and place thereof are announced at the meeting in which the
adjournment is taken.  At the adjourned meeting the Corporation may conduct any
business which might have been transacted at the original meeting. If the
adjournment is for more than thirty days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each shareholder of record entitled to vote at the
meeting.

     SECTION 2.5.  Quorum and Adjourned Meetings.  Unless otherwise provided by
law or the Corporation's Articles of Incorporation, a majority of the shares
entitled to vote, present in person or represented by proxy, shall constitute a
quorum at a meeting of shareholders.  If less than a majority of the shares
entitled to vote at a meeting of shareholders is present in person or
represented by proxy at such meeting, a majority of the shares so represented
may adjourn the meeting from time to time without further notice.  At any
adjourned meeting at which a quorum is present, any business may be transacted
which might have been transacted at the original meeting.  The shareholders
present at a meeting may continue to transact business until adjournment,
notwithstanding the withdrawal of such number of shareholders as may leave less
than a quorum.

     SECTION 2.6.  Fixing of Record Date.

     (a)  For the purpose of determining shareholders entitled to notice of or
to vote at any meeting of shareholders or any adjournment thereof, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which record date shall not be more than sixty nor less than ten
days before the date of such meeting.  If no record date is fixed by the Board
of Directors, the record date for determining shareholders entitled to notice of
or to vote at a meeting of shareholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held.  A determination of shareholders of record entitled to notice of or to
vote at a meeting of shareholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting;

                                      -2-
<PAGE>
 
     (b)  For the purpose of determining shareholders entitled to consent to
corporate action in writing without a meeting, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is established by the Board of Directors, and
which date shall not be more than ten (10) days after the date on which the
resolution fixing the record date is adopted by the Board of Directors.  If no
record date has been fixed by the Board of Directors, the record date for
determining shareholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the Board of Directors is required by
law, shall be the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the Corporation by delivery
to its registered office in the State of Ohio, its principal office, or an
officer or agent of the Corporation having custody of the book in which the
proceedings of meetings of shareholders are recorded.  Delivery to the
Corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested.  If no record date has been fixed by the Board
of Directors and prior action by the Board of Directors is required by law, the
record date for determining shareholders' consent to corporate action in writing
without a meeting shall be the close of business on the day on which the Board
of Directors adopts the resolution taking such prior action; and

     (c)  For the purpose of determining the shareholders entitled to receive
payment of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect to any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the Board of Directors may fix the record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted,
and which record date shall be not more than sixty (60) days prior to such
action.  If no record date is fixed, the record date for determining the
shareholders for any such purpose shall be the close of business on the day on
which the Board of Directors adopts the resolution relating thereto.

     SECTION 2.7.  Voting List.  The officer who has charge of the stock ledger
of the Corporation shall prepare and make, at least ten (10) days before every
meeting of shareholders, a complete list of shareholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
shareholder and the number of shares registered in the name of each shareholder.
Such list shall be open to the examination of any shareholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the place of the meeting during the
whole time thereof, and may be inspected by any shareholder who is present.

     SECTION 2.8.  Voting.  Unless otherwise provided by the Articles of
Incorporation, each shareholder shall be entitled to one vote for each share of
capital stock held by each shareholder. In all matters other than the election
of directors, the affirmative vote of the majority of shares present in person
or represented by proxy at the meeting and entitled to vote on the subject
matter shall be the act of the shareholders.  Directors shall be elected by
plurality of the votes of the 

                                      -3-
<PAGE>
 
shares present in person or represented by a proxy at the meeting entitled to
vote on the election of directors.

     SECTION 2.9.  Proxies.  Each shareholder entitled to vote at a meeting of
shareholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.  A duly executed proxy
shall be irrevocable if it states that it is irrevocable and if, and only as
long as, it is coupled with an interest sufficient in law to support an
irrevocable power.  A proxy may remain irrevocable regardless of whether the
interest with which it is coupled is an interest in the stock itself or an
interest in the Corporation generally.

     SECTION 2.10.  Ratification of Acts of Directors and Officers.  Except as
otherwise provided by law or by the Articles of Incorporation of the
Corporation, any transaction or contract or act of the Corporation or of the
directors or the officers of the Corporation may be ratified by the affirmative
vote of the holders of the number of shares which would have been necessary to
approve such transaction, contract or act at a meeting of shareholders, or by
the written consent of shareholders in lieu of a meeting.

     SECTION 2.11.  Informal Action of Shareholders.  Any action required to be
taken at any annual or special meeting of shareholders of the Corporation, or
any action which may be taken at any annual or special meeting of such
shareholders, may be taken without a meeting, without prior notice and without a
vote, if a consent or consents in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted.  Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those shareholders who
have not consented in writing.  In the event that the action which is consented
to is such as would have required the filing of a certificate with any
governmental body, if such action had been voted on by shareholders at a meeting
thereof, the certificate filed shall state, in lieu of any statement required by
law concerning any vote of shareholders, that written consent had been given in
accordance with the provisions of the General Corporation Law of Ohio, and that
written notice has been given as provided in such section.

     SECTION 2.12.  Organization.  Such person as the Board of Directors may
designate or, in the absence of such a designation, the President of the
Corporation or, in his or her absence, such person as may be chosen by the
holders of a majority of the shares entitled to vote who are present, in person
or by proxy, shall call to order any meeting of the shareholders and act as
chairman of such meeting.  In the absence of the Secretary of the Corporation,
the chairman of the meeting shall appoint a person to serve as secretary at the
meeting.

     SECTION 3.1.  Number and Tenure of Directors.  The number of directors of
the Corporation shall be no less than one (1) or no more than seven (7) members.

qualified or until such director's earlier resignation or removal.  Any director
may resign at any time upon written notice to the Corporation.

annual meeting of shareholders.  In all elections for directors, every
shareholder shall have the right to vote the number of shares owned by such

Directors may fix any place, either within or without the State of Ohio, as the
place for holding any special meeting of the Board of Directors called by them.

     SECTION 3.4.  Notice of Special Meetings of the Board of Directors.  Notice
of any special meeting of the Board of Directors shall be given at least one (1)
day previous thereto by written notice to each director at his or her address.
If mailed, such notice shall be deemed to be delivered when deposited in the
United States Mail so addressed, with first-class postage thereon prepaid.  If
sent by any other means (including facsimile, courier, or express mail, etc.),
such notice shall be deemed to be delivered when actually delivered to the home
or business address of the director.

     SECTION 3.5.  Quorum.  A majority of the total number of directors fixed by
these Regulations, or in the absence of a Regulation which fixes the number of
directors, the number stated in the Articles of Incorporation or named by the
incorporators, shall constitute a quorum for the transaction of business.  If
less than a majority of the directors are present at a meeting of the Board of
Directors, a majority of the directors present may adjourn the meeting from time
to time without further notice.

     SECTION 3.6.  Voting.  The vote of the majority of the directors present at
a meeting at which a quorum is present shall be the act of the Board of
Directors, unless the General Corporation Law of the State of Ohio or the
Articles of Incorporation requires a vote of a greater number.

     SECTION 3.7.  Vacancies.  Vacancies in the Board of Directors may be filled
by a majority vote of the Board of Directors or by an election either at an
annual meeting or at a special meeting of the shareholders called for that
purpose.  Any directors elected by the shareholders to 

                                      -5-

fill a vacancy shall hold office for the balance of the term for which he or she
was elected. A director appointed by the Board of Directors to fill a vacancy
shall serve until the next meeting of shareholders at which directors are
elected.

     SECTION 3.8.  Removal of Directors.  A director, or the entire Board of
Directors, may be removed, with or without cause, by the holders of a majority
of the shares then entitled to vote at an election of directors; provided,
however, that if cumulative voting obtains and less than the entire Board of
Directors is to be removed, no director may be removed without cause if the
votes cast against such director's removal would be sufficient to elect him if
then cumulatively voted at an election of the entire Board of Directors.

     SECTION 3.9.  Informal Action of Directors.  Unless otherwise restricted by
the Articles of Incorporation or these Regulations, any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof, may be taken without a meeting if all members of the Board of
Directors or committee, as the case may be, consent thereto in writing, and the
writing or writings are filed with the minutes of proceedings of the Board of
Directors or committee.

     SECTION 3.10.  Participation by Conference Telephone.  Members of the Board
of Directors, or any committee designated by such board, may participate in a
meeting of the Board of Directors, or committee thereof, by means of conference
telephone or similar communications equipment as long as all persons
participating in the meeting can speak with and hear each other, and
participation by a director pursuant to this Section 3.10 shall constitute
presence in person at such meeting.

     SECTION 4.1.  Written Waiver of Notice.  A written waiver of any required
notice, signed by the person entitled to notice, whether before or after the
date stated therein, shall be deemed equivalent to notice.  Neither the business

shareholders, directors or members of a committee of directors need be specified
in any written waiver of notice.

     SECTION 4.2.  Attendance as Waiver of Notice.  Attendance of a person at a
meeting shall constitute a waiver of notice of such meeting, except when the
person attends a meeting for the express purpose of objecting, and objects at

     SECTION 5.  General Provisions.  The Board of Directors may, by resolution
passed by a majority of the whole board, designate one or more committees, each
committee to consist of one or more of the directors of the Corporation.  The
board may designate one or more directors as alternate members of any committee,
who may replace any absent or disqualified member at any meeting of the
committee.  In the absence or disqualification of a member at any meeting of a
committee, the member or members thereof present at any meeting and not
disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in the place of any such absent or disqualified member.  Any such
committee, to the extent provided in the resolution of the Board of Directors,
shall have and may exercise all the powers and authority of the Board of
Directors in the management of the business and affairs of the Corporation, and
may authorize the seal of the Corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to amending the Articles of Incorporation, adopting an agreement of merger or
consolidation, recommending to the shareholders the sale, lease, or exchange of
all or substantially all of the Corporation's property and assets, recommending
to the shareholders a dissolution of the Corporation or a revocation of a
dissolution, or amending the Regulations of the Corporation; and, unless the
resolution so provides, no such committee shall have the power or authority to
declare a dividend, to authorize the issuance of stock or to adopt a certificate
of merger.

whenever, in its judgment, the best interests of the Corporation would be served
thereby, but such removal shall be without prejudice to the contract rights, if

such a resolution by the Board of Directors, every holder of stock represented
by certificates and upon request every holder of uncertificated shares shall be
entitled to have a certificate signed by, or in the name of the Corporation by
the Chairman or Vice Chairman of the Board of Directors, Chief Executive
Officer, or the President or Vice President, and by the Treasurer or an
Assistant Treasurer, or the Secretary or an Assistant Secretary of the
Corporation representing the number of shares registered in certificate form.
Any or all the signatures on the certificate may be a facsimile.

     SECTION 7.2.  Signatures of Former Officer, Transfer Agent or Registrar.
In case any officer, transfer agent, or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if such person or
entity were such officer, transfer agent or registrar at the date of issue.

     SECTION 7.3.  Transfer of Shares.  Transfers of shares of the Corporation
shall be made only on the books of the Corporation by the holder of record
thereof or by his legal representative, who shall furnish proper evidence of
authority to transfer, or by his or her attorney thereunto authorized by power
of attorney duly executed and filed with the Secretary of the Corporation, and
on surrender for cancellation of certificate for such shares.  Prior to due
presentment of a certificate for shares for registration of transfer, the
Corporation may treat a

registered owner of such shares as the person exclusively entitled to vote, to
receive notifications and otherwise have and exercise all of the right and
powers of an owner of shares.

     SECTION 7.4.  Lost, Destroyed or Stolen Certificates.  Whenever a
certificate representing shares of the Corporation has been lost, destroyed or
stolen, the holder thereof may file in the office of the Corporation an
affidavit setting forth, to the best of his knowledge and belief, the time,
place, and circumstance of such loss, destruction or theft together with a
statement of indemnity sufficient in the opinion of the Board of Directors to
indemnify the Corporation against any claim that may be made against it on
account of the alleged loss of any such certificate.  Thereupon the board may
cause to be issued to such person or such person's legal representative a new
certificate or a duplicate of the certificate alleged to have been lost,
destroyed or stolen.  In the exercise of its discretion, the Board of Directors
may waive the indemnification requirements provided herein.

                                INDEMNIFICATION
                                ---------------

     SECTION 11.1  Indemnification.  The Corporation shall indemnify, in
accordance with and to the full extent now or hereafter permitted by law, 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 (including, without limitation, any
action by or in the right of the Corporation), by reason of his acting as a
director of the Corporation (and the Corporation, in the sole discretion of the
Board of Directors, may so indemnify a person by reason of the fact that he is
or was an officer or employee of the Corporation or is or was serving at the
request of the Corporation in any other capacity for or on behalf of the
Corporation) against any liability or expense actually and reasonably incurred
by such person in respect thereof; provided, however, that the Corporation shall
not be obligated to indemnify any such director (i) with respect to proceedings,
claims or actions initiated or brought voluntarily by such person and not by way
of defense or brought against such person in response to a proceeding, claim or
action by such person against the Corporation, or (ii) for any amounts paid in
settlement of an action effected without the prior written consent of the
Corporation to such settlement or, (iii) if liability was incurred because the
director breached or failed to perform a duty he owes to the Corporation and the
breach or failure to perform constitutes (a) a willful failure to deal fairly
with the Corporation or its shareholders in connection with a matter in which
the director has a material conflict of interest, (b) a violation of criminal
law, unless the director had reasonable cause to believe his conduct was lawful
or no reasonable cause to believe his conduct was unlawful, (c) a transaction
from which the director derived an improper personal profit, or (d) willful
misconduct. The termination of a proceeding by judgment, order, settlement or
conviction, or upon a plea of no contest or an equivalent plea, shall not, by
itself, create a presumption that indemnification of the director or officer is
not required.  A director or officer who seeks indemnification shall make a
written request to the Corporation.  Such indemnification is not exclusive of
any other right to indemnification provided by law, agreement or otherwise.

     SECTION 11.2  Determination of Right to Indemnification.  Unless otherwise
provided by the Corporation's Articles of Incorporation, these Regulations, or
written agreement between the director or officer, the determination as to right
to indemnification shall be made by a majority vote of a quorum of the Board of
Directors consisting of directors not at the time parties to the same or related
proceedings.  If a quorum of disinterested directors cannot be obtained, the
determination will be made by majority vote of a committee duly appointed by the
Board of Directors and consisting solely of two or more directors not at the
time parties to the same or related proceedings.  Directors who are parties to
the same or related proceedings may participate in the designation of members of
the committee.
