brought before the annual meeting.

     The Chairman of an annual meeting shall, if the facts warrant, determine
and declare to the meeting that business was not properly brought before the
meeting in accordance with the provisions of this Section 1, and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted.

notice of a special meeting shall also set forth the objects of the meeting. All
or any of the stockholders may waive notice of the annual or any special
meeting, and the presence of a stockholder at any meeting, in person or by
proxy, shall be deemed a waiver of notice thereof by him. Meetings of the
stockholders may be held at any time and place and for any purpose, without
notice, when all of the stockholders entitled to vote at such meeting are
present in person or by proxy, or when all of such stockholders waive notice and
consent to the holding of such meeting.

     It shall be the duty of the officer who shall have charge of the stock
ledger of the Corporation to prepare and make, at least ten days before every
stockholders' meeting for the election of directors, a complete list of
stockholders entitled to vote thereat, arranged in alphabetical order. Such list
shall be open at the place where said election is to be held for said ten days,
to the examination of any stockholder, and shall be produced and kept at the
time and place of election during the whole time thereof, and subject to the
inspection of any stockholder who may be present.

entitled to one vote for each such share of capital stock standing registered in
his name at the time of the closing of the transfer books for said meeting, or
if such transfer books shall not have been closed for such meeting, then for
each such share of stock standing registered in his name at such date, if any,
as the Board of Directors shall have fixed in advance as hereinafter provided,
as a record for the determination of the stockholders entitled to notice of and
to vote at such meeting, or in case the transfer books shall not have been
closed for such meeting and no such record date shall have been fixed in advance
by the Board of Directors, then for each such share of stock standing registered
in his name at the time of the meeting; provided, however, that except where the
transfer books of the Corporation shall have been closed, or a date shall have
been fixed as a record date for the determination of the stockholders entitled
to vote, as hereinafter provided, no share of stock shall be voted on at any
election of directors which shall have been transferred on the books of the
Corporation within twenty days next preceding such election of directors. Such
vote may be given personally or by proxy authorized in writing. Only the persons
in whose names shares of stock shall stand on the books of the Corporation at

shares of stock standing in their names. No proxy shall be voted on or after
three years from its date, unless such proxy provides for a longer period.

total number of shares of stock issued and outstanding, and for the time being
entitled to be voted at any meeting, represented in person or by proxy, shall

of a larger number shall be required by law. In the absence of a quorum, the
stockholders attending or represented at the time and place at which a meeting
shall have been called may adjourn the meeting from time to time until a quorum
shall be present. At any such adjourned meeting at which a quorum shall be
present any business may be transacted which might have been transacted by a
quorum of the stockholders at the meeting as originally convened.

of the Corporation shall act as Secretary at all meetings of the stockholders,
but in their absence the stockholders or presiding officers may appoint a person
to act as Secretary of the meeting.

A director of the Corporation need not be a stockholder thereof. The Board of
Directors shall consist of five (5) directors. Such number may be increased
or decreased to such number as shall hereafter be fixed from time to time by
amendment of these By-Laws, provided the number of directors shall never be
less than three.

     Only persons who are nominated in accordance with the following
procedures shall be eligible for election as directors. Nominations for the
election of directors may be made by the Board of Directors or by a committee

nominations to the Secretary of the Corporation not later than (a) with
respect to an election to be held at an annual meeting of stockholders, no
earlier than March 1 and no later than March 25 immediately preceding the

disclosure of such meeting is made, whichever is earlier.

     Each such notice shall set forth: (a) the name and record address of the
stockholder who intends to make the nomination and the name, age, business
address and resident address of the person or persons to be nominated; (b) a
representation that the stockholder is a holder of record of stock of the
Corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notice and stating the number of shares held by such stockholder; (c) a
description of all arrangements or understandings involving any stockholder,
each such 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
stockholder or relating to the Corporation or its securities or to such
nominee's service as a director if elected; (d) such other information regarding
such nominee proposed by such stockholder as would be required to be disclosed
in solicitations for proxies for election of directors pursuant to Rule 14a
under the Securities Exchange Act of 1934, as amended; and (e) the consent of
each nominee to serve as a director of the Corporation if so elected.

     The Chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

     Vacancies and newly created directorships resulting from any increase in
the authorized number of directors may be filled by a majority of the directors
then in office, although less than a quorum, or by a sole remaining director.
Any director elected to fill a vacancy as hereinabove set forth shall hold
office until the next election of the class for which such director shall have
been chosen, and until his successor shall have been



                                       4

elected and qualified.

     When one or more directors shall resign from the Board effective at a
future date, a majority of the directors then in office, including those who
have so resigned, shall have power to fill such vacancy or vacancies; the vote

held at the principal office of the Corporation in Wilmington, Delaware, or at
the office of the Corporation in the Village of Franklin Park, Illinois, or at
any other place within or without the State of Delaware which may be from time
to time established by the By-Laws of the Corporation or by resolution of the
Board, or which may be agreed to in writing by all the directors of the
Corporation.

     Section 3. REGULAR AND SPECIAL MEETINGS. The regular annual meeting of the
Board of Directors shall be held without notice at the same place and
immediately following the close of the annual stockholders' meeting in each year
for the election of officers and the transaction of such other business as may
come before the Board. Other regular meetings of the Board may be held at such
times and places, either within or without the State of Delaware, and upon such
notice, or without notice, as the Board of Directors may by resolution from time
to time determine. Special meetings of the Board shall be held whenever called
by the President or any two directors, in writing. Notice of each special
meeting of the Board shall be delivered personally to each director, mailed to
him or transmitted by telephone, telegraph or facsimile transmission to his
residence or usual place of business, at least three days before the meeting or
such shorter period before the meeting as the person or persons calling such
meeting deem appropriate in the circumstances. Meetings of the Board may be held
at any time and place either within or without the State of Delaware, and for
any purpose, without notice, when all of the directors are present, or shall
waive notice of and consent to the holding of such meeting. All or any of the
directors may waive notice of any meeting, and the presence of a director at any
meeting of the Board shall be deemed a waiver of notice thereof by him.

     Section 4. QUORUM AND ADJOURNMENT. A majority of the directors in office at
a meeting regularly called shall constitute a quorum. In the absence of a
quorum, the directors present at the time and place at which a meeting shall
have been duly called, may adjourn the meeting from time to time and place to
place until a quorum shall be present.

     Section 5. SUBMISSION OF ACTS TO APPROVAL OF STOCKHOLDERS. The Board of
Directors, in its discretion, may submit any contract or act for approval or
ratification at any annual meeting of the stockholders, or at any special
meeting of the stockholders called for that purpose, and any contract or act
that shall be approved or ratified by the vote of the holders of a majority of
the capital stock of the Corporation, which is represented in person or by proxy
at such meeting, provided that a lawful quorum of stockholders be there
represented in person or by proxy, shall, unless the approval or



                                       5
<PAGE>

ratification of the holders of a larger proportion of the capital stock is
required by law, or by the Certificate of Incorporation of the Corporation, be
as valid and as binding upon the Corporation and upon all the stockholders as if
it had been approved or ratified by every stockholder of the Corporation.

     Section 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          (a)  The Corporation shall, to the fullest extent to which it is
empowered to do by the General Corporation Law of Delaware or any other
applicable laws, as may from time to time be in effect, indemnify any person who
was or is, 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 or officer of the Corporation,
or is or was serving at the request of the Corporation as a director or officer
of another corporation, partnership, joint venture, trust or other enterprise,
against all expenses (including attorneys' fees,) judgments, fines and amounts
paid in settlement actually and reasonably 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, order, 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. The Corporation may
make advances against any such expenses upon terms determined by the Board of
Directors.

          (b)  The Corporation shall have power to 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 for negligence or misconduct in the performance of
his duty to the Corporation unless and only to the extent that the Court of
Chancery or 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
indemnify for such expenses which the Court of Chancery or such other court
shall deem proper.

          (c)  To the extent that a director, officer, employee or agent of the



                                       6
<PAGE>

Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsections (a) and (b) of this
Section 6, 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.

          (d)  Any indemnification under subsections (a) and (b) of this Section
6 (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 subsections (a) and (b)
of this Section 6. Such determination shall be made (1) by the Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, or (2) 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 (3) by the
stockholders.

          (e)  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 unless it shall
ultimately be determined that he is entitled to be indemnified by the
Corporation as authorized in this section.

          (f)  Persons who are not covered by the foregoing provisions of this
Section 6 and who are or were employees or agents of the Corporation, or are or
were serving at the request of the Corporation as employees or agents of another
corporation, partnership, joint venture, trust or other enterprise, may be
indemnified to the extent authorized at any time or from time to time by the
Board of Directors.

          (g)  The indemnification provided by this Section 6 shall not be
deemed exclusive of any other rights to which those seeking indemnification may
be entitled under any By-Law, agreement, vote of stockholders 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. AUDIT COMMITTEE. The directors shall appoint from their number
an Audit Committee which shall consist of two (2) Unaffiliated Directors, who
shall hold office until their successors are elected, or until they resign. The

Board of Directors. The Audit Committee may make its own rules of procedure and
shall meet as and where provided by rules or as designated by its Chairman. The
members of the Audit Committee shall select a member as Chairman.

shall hold office until their successors are elected, or until they resign. The
Compensation Committee shall perform the functions designated by the
Corporation's Board of Directors. The Compensation Committee may make its own
rules of procedure and shall meet as and where provided by rules or as
designated by its Chairman. The members of the Compensation Committee shall
select a member as Chairman.

     Section 9. UNAFFILIATED DIRECTORS. An Unaffiliated Director is a director
that is not a present or former employee of the Corporation or any of its
affiliates and does not have any direct or indirect material economic
relationships with the Corporation or any of its affiliates other than as a
result of customary director's compensation or stock ownership.

the City of Chicago, Illinois, or elsewhere, as transfer agent or registrar of
transfers for facilitating transfers by stockholders under such regulations as
the Board of Directors may from time to time prescribe. Upon such appointment
being made, all stock certificates thereafter issued shall be countersigned by
such transfer agent or registrar of transfers, or both, as the

     The Board of Directors shall have power to close the stock transfer books
of the Corporation for a period not exceeding forty days preceding the date of
any meeting of stockholders or the date for the payment of any dividend or the
date for the allotment of rights or the date when any change or conversion of
exchange of capital stock shall go into effect; provided, however, that in lieu
of closing the stock transfer books as aforesaid, said Board of Directors may
fix in advance a date, not exceeding sixty days preceding the date of any
meeting of stockholders or the date for the payment of any dividend, or the date
of the allotment of rights, or the date when any change or conversion or
exchange of capital stock shall go into effect, as a record date for the
determination of the stockholders entitled to notice of and to vote at any such
meeting, or entitled to receive payment of any such dividend, or to any such
allotment or rights, or to exercise the rights in respect of any such change,
conversion or exchange of capital stock, and in such case only such stockholders
as shall be stockholders of record on the date so fixed shall be entitled to
such notice of, and to vote at, such meeting, or to receive payment of such
dividend, or to receive such allotment of rights, or to exercise such rights, as
the case may be, notwithstanding any transfer of any stock on the books of the
Corporation after any such record date fixed as aforesaid.

     Section 3. ADDRESS OF STOCKHOLDERS. Every stockholder shall furnish the
Secretary with an address to which notices of meetings and all other notices may
be served upon or mailed to him, and in default thereof notices may be addressed

Park, Illinois.

     Section 4. LOST AND DESTROYED CERTIFICATES. The Board of Directors may
direct that a new certificate or certificates may be issued in place of any
certificate or certificates theretofore issued by the Corporation alleged to
have been lost or destroyed, and the Board of Directors, when authorizing the
issuance of such new certificate or certificates, may in their discretion, and
as a condition precedent thereto, require the owner of such lost or destroyed
certificate or certificates, or his legal representatives to give to the
Corporation a bond in such sum as they may direct, as indemnify against any
claim that may be made against the Corporation.

     Section 5. REGULATIONS. The Board of Directors shall have power and
authority to make all such rules and regulations as they may deem expedient
concerning the issue, transfer and registration of certificates for shares of
the capital stock of the Corporation.
