          a majority within each class when class voting applies.

          not signed the consent must be promptly notified of the passage of the
          amendment.                                     (Sections 7.10 & 10.20)

each other, and such participation in a meeting shall constitute presence in
person at the meeting.

        SECTION 9. QUORUM. A majority of the directors shall constitute a quorum
for the transaction of business. If at any meeting of the board there shall be
less than a quorum present, a majority of those present may adjourn the meeting

<PAGE>   5
participate in the Director Stock Option Plan or such other benefit plans as
they shall determine. No such payment shall preclude any director from serving
the corporation in any other capacity and receiving compensation therefor.

        SECTION 11. ACTION WITHOUT MEETING. 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 prior to such action a written consent

                                  MISCELLANEOUS

        SECTION 1. CERTIFICATES OF STOCK. Every holder of stock in the
corporation shall be entitled to have a certificate certifying the number of
shares owned by him in the corporation, signed by the Chairman, the President or
the Vice President and the Treasurer or an Assistant Treasurer, or Secretary or
an Assistant Secretary. Where a certificate is countersigned (1) by a transfer
agent other than the corporation or its employee, or (2) by a registrar other
than the corporation or its employee, any other signature on the certificate may
be facsimile. 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

                                       6
<PAGE>   7
certificate is issued, it may be issued by the corporation with the same effect
as if he were such officer, transfer agent or registrar at the date of issue.

        SECTION 2. LOST CERTIFICATES. A new certificate of stock may be issued
in the place of any certificate theretofore issued by the corporation, alleged
to have been lost, stolen or destroyed, and the directors may, in their
discretion, require the owner of the lost, stolen or destroyed certificate, or
his legal representative, to give the corporation a bond, in such sum as they
may direct, sufficient to indemnify the corporation against any claim that may
be made against it on account of the alleged loss, theft or destruction of any
such certificate, or the issuance of any such new certificate.

        SECTION 3. TRANSFER OF SHARES. Upon surrender to the corporation or
transfer agent of the corporation of a certificate for shares duly endorsed or
accompanied by proper- evidence of succession, assignment of authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books. Whenever any transfer of shares shall be made for
collateral security, and not absolutely, it shall be so expressed in the entry
of transfer if, when certificates are presented to the corporation for transfer,
both the transferor and the transferee request the corporation to do so.

        SECTION 4. SHAREHOLDERS RECORD DATE. In order that the corporation may
determine the Shareholders entitled to notice of or to vote at any meeting of
Shareholders or any adjournment thereof or to express consent to corporate
action in writing without a meeting, or entitled to receive payment of any
dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful action, the Board of Directors may fix, in
advance, a record date, which shall not be more than sixty (60) nor less than
ten (10) days before the date of such meeting or in the case of a merger,
consolidation, share exchange, dissolution or sale, lease or exchange of assets,
not less than twenty (20) days, nor more than sixty (60) days prior to any other
action. 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.

        SECTION 5. REGISTERED SHAREHOLDERS. The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books, as the owner of
shares, and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Illinois.

        SECTION 6. DIVIDENDS. Subject to the provisions of the Articles of
Incorporation, the Board of Directors may, out of funds legally available
therefor at any regular or special meeting declare dividends upon the capital
stock of the corporation as and when they deem expedient. Dividends may be paid
in cash, in property, or in shares of capital stock of the corporation, subject
to the provisions of the Articles of Incorporation. Before declaring any

                                       7
<PAGE>   8
dividend there may be set apart out of any funds of the corporation available
for dividends, such sum or sums as the directors from time to time in their
discretion deem proper for working capital or as a reserve fund to meet
contingencies or for equalizing dividends or for such other purposes as the
directors shall deem conducive to the interests of the corporation.

        SECTION 7. SEAL. The corporate seal shall be circular in form and shall
contain the name of the corporation, the year of its creation and the words
"CORPORATE SEAL ILLINOIS." Said seal may be used by causing it or a facsimile
thereof to be impressed or affixed or reproduced or otherwise.

        SECTION 8. FISCAL YEAR. The fiscal year of the corporation shall be
determined by resolution of the Board of Directors.

        SECTION 9. CHECKS. All checks, drafts or other orders for the payment of
money, notes or other evidences of indebtedness issued in the name of the
corporation shall be signed by such officer or officers, agent or agents of the
corporation, and in such manner as shall be determined from time to time by
resolution of the Board of Directors.

        SECTION 10. NOTICE AND WAIVER OF NOTICE. Whenever any notice is required
by these By-Laws to be given, personal notice is not meant unless expressly so
stated, and any notice so required shall be deemed to be sufficient if given by
depositing the same in the United States mail, postage prepaid, addressed to the
person entitled thereto at his address as it appears on the records of the
corporation, and such notice shall be deemed to have been given on the day of
such mailing. Shareholders not entitled to vote shall not be entitled to receive
notice of any meetings except as otherwise provided by statute.

        Whenever any notice whatever is required to be given under the
provisions of any law, or under the Provisions of the Articles of Incorporation
of the corporation or these By-Laws, a waiver thereof in writing, signed by the
person or persons entitled to said notice, whether before or after the time
stated therein, shall be deemed equivalent thereto. 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, at the beginning
of the meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor the
purpose of any regular or special meeting of the Shareholders, directors or
members of a committee of directors need be specified in any written waiver of
notice.

                                   ARTICLE VI

                               INDEMNIFICATION OF
                         DIRECTORS, EMPLOYEES AND AGENTS

        SECTION 1. 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 (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer,

                                       8
<PAGE>   9
employee or agent of the corporation, or who is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees). Judgments, fines and amounts paid in
settlement actually and reasonable incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment or settlement, conviction or upon a plea
of nolo contendere or its equivalent, shall not, of itself, create a presumption
that the person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the corporation, and
with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.

        SECTION 2. The corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such Person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall determine upon
application, that despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper.

        SECTION 3. To the extent that a director, officer, employee or agent of
a corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Sections 1 and 2, or in defense of any
claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

        SECTION 4. Any indemnification under Sections 1 and 2 (unless ordered by
a court) shall be made by the corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Sections 1 and 2. Such determination
shall be made (a) by the Board of Directors by a majority vote of a quorum
consisting of directors who were not parties to such action, suit or
proceedings, or (b) if such a quorum is not obtainable, or, even if obtainable,
a quorum of disinterested directors so directs, by independent legal counsel in
a written opinion, or (c) by the Shareholders.

        SECTION 5. Expenses incurred in defending a civil or criminal action,
suit or proceeding may be paid by the corporation in advance of the final
disposition of such action, suit or proceeding as authorized by the Board of
Directors in the specific case upon receipt of an undertaking by or on behalf of
the director, officer, employee or agent to repay such amount,

                                       9
<PAGE>   10
unless it shall ultimately be determined that he is entitled to be indemnified
by the corporation authorized in this Article.

        SECTION 6. The indemnification provided by this article shall not be
deemed exclusive of any other rights to which those indemnified may be entitled
under any contract, 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, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

        SECTION 7. The corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under the provisions of this Article.

                                   ARTICLE VII

                                   AMENDMENTS

        These By-Laws may be altered or repealed and By-Laws may be made at any
annual meeting of the Shareholders or at any special meeting thereof if notice
of the proposed alteration or repeal or By-Law or By-Laws to be made be
contained in the notice of such special meeting, by the affirmative vote of a
majority of the stock issued and outstanding and entitled to vote thereat, or by
the affirmative vote of a majority of the Board of Directors, at any regular
meeting of the Board of Directors, or at any special meeting of the Board of
Directors, if notice of the proposed alteration or repeal, or By-Law or By-Laws
to be made, be contained in the notice of such special meeting.
