If the day fixed for the annual meeting shall be a legal holiday such meeting

at any adjournment thereof, the Board of Directors shall cause the election to

Board of Directors of the Corporation may close its stock transfer books for a
period not exceeding thirty days preceding the date of any meeting of
shareholders, 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 or exchange of shares shall be effective; or, in lieu
thereof, may fix in advance a date, not exceeding thirty days preceding the date
of any meeting of shareholders, or the date for the payment of any dividend, or
the date for the allotment of rights, or the date when any exchange or
conversion of or exchange of shares shall be effective, as the record date for
the determination of the shareholders entitled to notice of, and to vote at,
such meeting, and any adjournment thereof, or entitled to receive payment of any
such dividend, or to receive any such allotment of rights, or to exercise such
rights, in the event of any change, conversion or exchange of shares, as the
case may be. If the Board of Directors shall not have closed the transfer books
or set a record date for the determination of the shareholders as hereinabove
provided, the date of which notice of the meeting is mailed, or the date such
dividend is declared, or other right announced, as the case may be, shall be the
record date for such determination of shareholders.

         Section 8. Voting Lists: At least ten days before each meeting of

days prior to such meeting, shall be kept on file at the registered office of
the Corporation and shall be subject to inspection by any shareholder at any
time during usual business hours. Such list shall also be produced and kept open
at the time and place of the meeting and shall be subject to the inspection of
any shareholder during the whole time of the meeting. The original share ledger
or transfer book, or a duplicate



thereof kept in this state, shall be prima facie evidence as to whom are the
shareholders entitled to examine such list or share ledger or transfer book or
to vote at any meeting of shareholders.

         Section 9. Quorum: A majority of the outstanding shares of the
Corporation entitled to vote, represented in person or by proxy, shall

from time to time, without further notice, to a date not longer than ninety days
from the date originally set for such meeting.

Corporation before or at the time of the meeting. No proxy shall be valid after
eleven months from the date of its execution, unless otherwise provided in the
proxy.

each outstanding share, regardless of class, shall be entitled to one vote upon
each matter submitted to a vote at a meeting of shareholders.

         Section 12. Voting of Shares by Certain Holders: Shares standing in the
name of another corporation, domestic or foreign, may be voted by such officer,
agent, or proxy as the By-Laws of such corporation may prescribe, or, in the

determine.

         Shares standing in the name of a deceased person may be voted by his
administrator or executor, either in person or by proxy, upon due proof of
qualification as



such. Shares standing in the name of a guardian, curator, or trustee may be
voted by such fiduciary, either in person or by proxy, but not guardian, curator
or trustee shall be entitled, as such fiduciary, to vote shares held by him
without a transfer of such shares into his name.

         Shares standing in the name of a receiver may be voted by such
receiver, and shares held by or under the control of a receiver may be voted by
such receiver without the transfer thereof into his name if authority to do so
be contained in an appropriate order of the court by which such receiver was
appointed.

         A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledges, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

         Section 13. Cumulative Voting for Directors: In all elections for
directors, each shareholder entitled to vote shall have the right to cast as
many votes in the aggregate as shall equal the number of shares held by him
multiplied by the number of directors to be elected at such election, and each
shareholder may cast the whole number of his votes for one candidate or
distribute them among two or more candidates as he shall see fit.

         Section 14. Consent of all Shareholders in Lieu of Meetings: Any action
required by "The General and Business Corporation Law of Missouri" to be taken
at a meeting of the shareholders, or any action which may be taken at a meeting
of shareholders under the provisions of these By-Laws or otherwise, may be taken
without a meeting if consents in writing, setting forth the action so taken,
shall be signed by all of the shareholders, severally or collectively, entitled
to vote with respect to the subject matter thereof. Such consents shall have the
same force and effect as a unanimous vote of the shareholders at a meeting duly
held,



and may be stated as such in any certificate or document required to be filed by
law. The Secretary of the Corporation shall file such consents with the minutes
of the meetings of the shareholders.

meeting of the shareholders. Each director shall hold office from the time of

shareholders in the manner hereinafter provided.

         Section 3. Regular Meetings: The annual meeting of the Board of
Directors shall be held without other notice than this By-Law, immediately

without other notice than such resolution.

         Section 4. Special Meetings: Special meetings of the Board of Directors
may be called by or at the request of the President, or any two directors. The
person or persons authorized to call special meetings of the Board of Directors
may fix any place, either within or without the State of Missouri, as the place
for holding any special meeting of the Board of Directors called by them.


         Section 5. Notice: Notice of any special meeting shall be given at
least five days previously thereto by written notice delivered personally or
mailed to each director at his business address, or by telegram. If mailed, such
notice shall be deemed to be delivered when deposited in the United States mail
in a sealed envelope so addressed, with postage thereon prepaid. If notice be
given by telegram, such notice shall be deemed to be delivered when the telegram
is delivered to the telegraph company. Any director may waive notice of any
meeting. The attendance of a director at any meeting shall constitute a waiver
of notice of such meeting, unless a director attends a meeting for the express
purpose of objecting to the transaction of any business because the meeting is
not lawfully called or convened and so states at said meeting. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the Board of Directors need be specified in the notice or waiver of notice of
such meeting.

         Section 6. Quorum: A majority of the Board of Directors shall
constitute a quorum for the transaction of business at any meeting of the Board
of Directors, provided that if less than a majority of the directors are present
at such meeting, a majority of the directors present may adjourn the meeting
from time to time without further notice.

         Section 7. Manner of Acting: If all of the directors shall meet at any
time and place, either within or without the State of Missouri, without
objecting to the call or convening of the meeting, or if all of the directors
consent to the holding of a meeting irrespective of any notice, such meeting
shall be valid. The act of the majority of the directors present at a meeting of
the directors at which a quorum is present shall be the act of the Board of
Directors.


         Section 8. Consent of All Directors in Lieu of Meetings: If all of the
directors of the Corporation, severally or collectively, consent in writing to
any action required to be taken, or which may be taken, by the Board of
Directors, such consents shall have the same force and effect as a unanimous
vote of the directors at a meeting duly held, and may be stated as such in any
certificate or document required to be filed by law. The Secretary of the
Corporation shall file such consents with the minutes of the meetings of the
Board of Directors.

         Section 9. Vacancies: In the case of the death of or resignation or
disqualification or one or more of the directors, a majority of the survivors or
remaining directors may fill such vacancy or vacancies, by appointment, until
the successor or successors are elected at a meeting of the shareholders. A
director appointed to fill a vacancy shall serve as such until the next annual
meeting of the shareholders, or until he shall die, resign, or be removed by the
shareholders in the manner hereinafter provided.

         Section 10. Removal: Any director of the Corporation may be removed,
with or without cause or hearing, at any meeting of the shareholders by the
unanimous vote of all of the shareholders of the Corporation entitled to vote at
such meeting, or by an instrument in writing filed with the Secretary and
executed by all of the shareholders of record on the transfer books of the
Corporation on the date of such execution. Said shareholders shall also, at said
meeting or in such instrument, appoint a successor director to fill the vacancy
of the director so removed, which successor director shall serve until the next
annual meeting of the shareholders, or until he shall die, resign, or be removed
by the shareholders in the manner herein provided.


         Section 11. Compensation: Directors as such shall not receive any
stated salaries for their services, but by resolution of the Board of Directors,
a fixed fee and expenses of attendance, if any, may be allowed for attendance at
each regular or special meeting of the Board of Directors; provided, that
nothing herein contained shall be construed to preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor.
