                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 1.           DESCRIPTION OF SECURITIES TO BE REGISTERED.

                  On September 15, 1998, the Board of Directors of Butler
Manufacturing Company (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, without
par value ("Common Shares") of the Company. The dividend is payable on October
1, 1998 (the "Record Date") to the shareholders of record on that date. Each
Right entitles the registered holder to purchase from the Company one
one-hundredth of a share of Series A, Class 1 Preferred Stock, without par value
(the "Preferred Shares"), of the Company at a price of $160 per one
one-hundredth of a Preferred Share (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and UMB Bank, N.A., as
Rights Agent (the "Rights Agent").

                  Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 15% or more of the
outstanding Common Shares or (ii) 10 business days (or such later date as may be
determined by action of the Board of Directors prior to such time as any person
or group of affiliated persons becomes an Acquiring Person) following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the outstanding Common Shares
(the earlier of such dates being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate. A copy of
the Summary of Rights to Purchase Common Stock (the "Summary of Rights") will be
sent to holders as of the Record Date.

                  The Rights Agreement provides that, until the Distribution
Date (or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Common Shares. Until the Distribution Date
(or earlier redemption or expiration of the Rights), new Common Share
certificates issued after the Record Date upon transfer or new issuance of
Common Shares will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for Common Shares
outstanding as of the Record Date, even without such notation or a copy of the
Summary of Rights being attached thereto, will also constitute the transfer of
the Rights associated with the Common Shares represented by such cer-

                                      -1-
<PAGE>

tificate. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Shares as of the close of business on the
Distribution Date and such separate Right Certificates alone will evidence the
Rights.

                  The Rights are not exercisable until the Distribution Date.
The Rights will expire on September 30, 2008 (the "Final Expiration Date"),
unless the Final Expiration Date is extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case, as described below.

                  The Purchase Price payable, and the number of Preferred Shares
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion price,
less than the then-current market price of the Preferred Shares or (iii) upon
the distribution to holders of the Preferred Shares of evidences of indebtedness
or assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

                  The number of outstanding Rights and the number of one
one-hundredths of a Preferred Share issuable upon exercise of each Right are
also subject to adjustment in the event of a stock split of the Common Shares or
a stock dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

                  Preferred Shares purchasable upon exercise of the Rights will
not be redeemable. Each Preferred Share will be entitled to a minimum
preferential quarterly dividend payment of $1 per share but will be entitled to
an aggregate dividend of 100 times the dividend declared per Common Share. In
the event of liquidation, the holders of the Preferred Shares will be entitled
to a minimum preferential liquidation payment of $100 per share but will be
entitled to an aggregate payment of 100 times the payment made per Common Share.
Each Preferred Share will have one vote, voting together with the Common Shares.
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged, each Preferred Share will be entitled to receive
100 times the amount received per Common 

                                      -2-
<PAGE>

Share. These rights are protected by customary antidilution provisions.

                  In the event that the Company is acquired in a merger or other
business combination transaction or 50% or more of its consolidated assets or
earning power are sold after a person or group has become an Acquiring Person,
proper provision will be made so that each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereafter be void), will
thereafter have the right to receive, upon the exercise thereof at the then
current exercise price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction will have a market
value of two times the exercise price of the Right. In the event that any person
or group of affiliated or associated persons becomes an Acquiring Person, proper
provision shall be made so that each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereafter be void), will
thereafter have the right to receive upon exercise that number of Common Shares
having a market value of two times the exercise price of the Right.

                  At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50% or more of
the outstanding Common Shares, the Board of Directors of the Company may
exchange the Rights (other than Rights owned by such person or group which will
have become void), in whole or in part, at an exchange ratio of one Common Share
or one one-hundredth of a Preferred Share per Right.

                  With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments require an adjustment of at least
1% in such Purchase Price. No fractional Preferred Shares will be issued (other
than fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

                  At any time prior to the acquisition by a person or group of
affiliated or associated persons of beneficial ownership of 15% or more of the
outstanding Common Shares, the Board of Directors of the Company may redeem the
Rights in whole, but not in part, at a price of $.01 per Right (the "Redemption
Price"). The redemption of the Rights may be made effective at such time on such
basis with such conditions as the Board of Directors in its sole discretion may
establish. Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate 

                                      -3-
<PAGE>

and the only right of the holders of Rights will be to receive the Redemption
Price.

                  The terms of the Rights may be amended by the Board of
Directors of the Company without the consent of the holders of the Rights,
including an amendment to lower certain thresholds described above to not less
than the greater of (i) the sum of .001% and the largest percentage of the
outstanding Common Shares then known to the Company to be beneficially owned by
any person or group of affiliated or associated persons and (ii) 10%, except
that from and after such time as any person or group of affiliated or associated
persons becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights.

                  Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.

                  The Rights Agreement, dated September 16, 1998, between the
Company and UMB Bank, N.A., as Rights Agent, specifying the terms of the Rights
is attached hereto as an exhibit and is incorporated herein by reference. The
foregoing description of the Rights is qualified in its entirety by reference to
such exhibit.

                  AGREEMENT, dated as of September 16, 1998, between BUTLER
MANUFACTURING COMPANY, a Delaware corporation (the "Company"), and UMB BANK,
N.A., as rights agent (the "Rights Agent").

                  The Board of Directors of the Company has authorized and
declared a dividend of one preferred share purchase right (a "Right") for each
Common Share (as hereinafter defined) of the Company outstanding on October 1,
1998 (the "Record Date"), each Right representing the right to purchase one
one-hundredth of a Preferred Share (as hereinafter defined), upon the terms and
subject to the conditions herein set forth, and has further authorized and
directed the issuance of one Right with respect to each Common Share that shall
become outstanding between the Record Date and the earliest of the Distribution
Date, the Redemption Date and the Final Expiration Date (as such terms are
hereinafter defined).

                  Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

                  SECTION 1. CERTAIN DEFINITIONS. For purposes of this
Agreement, the following terms have the meanings indicated:

                   (a) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, together with all Affiliates and Associates
(as such terms are hereinafter defined) of such Person, shall be the Beneficial
Owner (as such term is hereinafter defined) of 15% or more of the Common Shares
of the Company then outstanding, but shall not include the Company, any
Subsidiary (as such term is hereinafter defined) of the Company, any employee
benefit plan of the Company or any Subsidiary of the Company, or any entity
holding Common Shares for or pursuant to the terms of any such plan (each an
"Exempt Person"). Notwithstanding the foregoing, no Person shall become an
"Acquiring Person" as the result of an acquisition of Common Shares by the
Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such Person to 15% or more
of the Common Shares of the Company then outstanding; provided, however, that if
a Person shall become the Beneficial Owner of 15% or more of the Common Shares
of the Company then outstanding by reason of share purchases by the Company and
shall, after such 

<PAGE>

share purchases by the Company, become the Beneficial Owner of any additional
Common Shares of the Company, then such Person shall be deemed to be an
"Acquiring Person." Notwithstanding the foregoing, if the Board of Directors of
the Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), has become such inadvertently, and such Person divests as
promptly as practicable a sufficient number of Common Shares so that such Person
would no longer be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), then such Person shall not be deemed to be an
"Acquiring Person" for any purposes of this Agreement.

                   (b) "Affiliate" and "Associate" shall have the respective
meanings ascribed to such terms in Rule 12b-2 of the General Rules and
Regulations under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), as in effect on the date of this Agreement.

                   (c) A Person shall be deemed the "Beneficial Owner" of and
shall be deemed to "beneficially own" any securities:

                           (i) which such Person or any of such Person's
         Affiliates or Associates beneficially owns, directly or indirectly;

                           (ii) which such Person or any of such Person's
         Affiliates or Associates has (A) the right to acquire (whether such
         right is exercisable immediately or only after the passage of time)
         pursuant to any agreement, arrangement or understanding (other than
         customary agreements with and between underwriters and selling group
         members with respect to a bona fide public offering of securities), or
         upon the exercise of conversion rights, exchange rights, rights (other
         than these Rights), warrants or options, or otherwise; provided,
         however, that a Person shall not be deemed the Beneficial Owner of, or
         to beneficially own, securities tendered pursuant to a tender or
         exchange offer made by or on behalf of such Person or any of such
         Person's Affiliates or Associates until such tendered securities are
         accepted for purchase or exchange; or (B) the right to vote pursuant to
         any agreement, arrangement or understanding; provided, however, that a
         Person shall not be deemed the Beneficial Owner of, or to beneficially
         own, any security 


                                      -2-
<PAGE>

         if the agreement, arrangement or understanding to vote such security
         (1) arises solely from a revocable proxy or consent given to such
         Person in response to a public proxy or consent solicitation made
         pursuant to, and in accordance with, the applicable rules and
         regulations promulgated under the Exchange Act and (2) is not also then
         reportable on Schedule 13D under the Exchange Act (or any comparable or
         successor report); or

                           (iii) which are beneficially owned, directly or
         indirectly, by any other Person with which such Person or any of such
         Person's Affiliates or Associates has any agreement, arrangement or
         understanding (other than customary agreements with and between
         underwriters and selling group members with respect to a bona fide
         public offering of securities) for the purpose of acquiring, holding,
         voting (except to the extent contemplated by the proviso to Section
         1(c)(ii)(B)) or disposing of any securities of the Company.

                  Notwithstanding anything in this definition of Beneficial
Ownership to the contrary, the phrase "then outstanding," when used with
reference to a Person's Beneficial Ownership of securities of the Company, shall
mean the number of such securities then issued and outstanding together with the
number of such securities not then actually issued and outstanding which such
Person would be deemed to own beneficially hereunder.

                   (d) "Business Day" shall mean any day other than a Saturday,

appointment. The Company may from time to time appoint such co-Rights Agents as
it may deem necessary or desirable.

                  SECTION 3. ISSUE OF RIGHT CERTIFICATES. (a) Until the earlier
of (i) the tenth day after the Shares Acquisition Date or (ii) the tenth
Business Day (or such later date as may be determined by action of the Board of
Directors prior to such time as any Person becomes an Acquiring Person) after
the date of the commencement by any Person (other than an Exempt 


                                      -4-
<PAGE>

Person) of, or of the first public announcement of the intention of any Person
(other than an Exempt Person) to commence, a tender or exchange offer the
consummation of which would result in any Person becoming the Beneficial Owner
of Common Shares aggregating 15% or more of the then outstanding Common Shares
(including any such date which is after the date of this Agreement and prior to
the issuance of the Rights; the earlier of such dates being herein referred to
as the "Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of Section 3(b) hereof) by the certificates for Common Shares
registered in the names of the holders thereof (which certificates shall also be
deemed to be Right Certificates) and not by separate Right Certificates, and (y)
the right to receive Right Certificates will be transferable only in connection
with the transfer of Common Shares. As soon as practicable after the
Distribution Date, the Company will prepare and execute, the Rights Agent will
countersign, and the Company will send or cause to be sent (and the Rights Agent
will, if requested, send) by first-class, insured, postage-prepaid mail, to each
record holder of Common Shares as of the close of business on the Distribution
Date, at the address of such holder shown on the records of the Company, a Right
Certificate, in substantially the form of Exhibit B hereto (a "Right
Certificate"), evidencing one Right for each Common Share so held. As of the
Distribution Date, the Rights will be evidenced solely by such Right
Certificates.

                  (b) On the Record Date, or as soon as practicable thereafter,
the Company will send a copy of a Summary of Rights to Purchase Preferred
Shares, in substantially the form of Exhibit C hereto (the "Summary of Rights"),
by first-class, postage-prepaid mail, to each record holder of Common Shares as
of the close of business on the Record Date, at the address of such holder shown
on the records of the Company. With respect to certificates for Common Shares
outstanding as of the Record Date, until the Distribution Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together with a copy of the Summary of Rights deemed to be attached thereto.
Until the Distribution Date (or the earlier of the Redemption Date or the Final
Expiration Date), the surrender for transfer of any certificate for Common
Shares outstanding on the Record Date, with or without a copy of the Summary of
Rights attached thereto, shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

<PAGE>

                  (c) Certificates for Common Shares which become outstanding
(including, without limitation, reacquired Common Shares referred to in the last
sentence of this paragraph (c)) after the Record Date but prior to the earliest
of the Distribution Date, the Redemption Date or the Final Expiration Date shall
have impressed on, printed on, written on or otherwise affixed to them the
following legend:

                           This certificate also evidences and entitles the
                  holder hereof to certain rights as set forth in a Rights
                  Agreement between Butler Manufacturing Company and UMB Bank,
                  N.A., as Rights Agent in effect on the date hereof (the
                  "Rights Agreement"), the terms of which are hereby
                  incorporated herein by reference and a copy of which is on
                  file at the principal executive offices of Butler
                  Manufacturing Company. Under certain circumstances, as set
                  forth in the Rights Agreement, such Rights (as defined in the
                  Rights Agreement) will be evidenced by separate certificates
                  and will no longer be evidenced by this certificate. Butler
                  Manufacturing Company will mail to the holder of this
                  certificate a copy of the Rights Agreement without charge
                  after receipt of a written request therefor. Under certain
                  circumstances, as set forth in the Rights Agreement, Rights
                  acquired or beneficially owned by, or issued to, any person
                  who becomes an Acquiring Person (as defined in the Rights
                  Agreement) may become null and void.

                  With respect to such certificates containing the foregoing
legend, until the Distribution Date, the Rights associated with the Common
Shares represented by such certificates shall be evidenced by such certificates
alone, and the surrender for transfer of any such certificate shall also
constitute the transfer of the Rights associated with the Common Shares
represented thereby. In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.

                  SECTION 4. FORM OF RIGHT CERTIFICATES. The Right Certificates
(and the forms of election to purchase Preferred Shares and of assignment to be
printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be 


                                      -6-
<PAGE>

required to comply with any applicable law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any stock exchange on which
the Rights may from time to time be listed, or to conform to usage. Subject to
the provisions of Section 22 hereof, the Right Certificates shall entitle the
holders thereof to purchase such number of one one-hundredths of a Preferred
Share as shall be set forth therein at the price per one one-hundredth of a
Preferred Share set forth therein (the "Purchase Price"), but the number of such
one one-hundredths of a Preferred Share and the Purchase Price shall be subject
to adjustment as provided herein.

                  SECTION 5. COUNTERSIGNATURE AND REGISTRATION. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its Chief Executive Officer, its President, any of its Vice Presidents,
or its Treasurer, either manually or by facsimile signature, shall have affixed
thereto the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be manually countersigned by
the Rights Agent and shall not be valid for any purpose unless countersigned. In
case any officer of the Company who shall have signed any of the Right
Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent
and issued and delivered by the Company with the same force and effect as though
the person who signed such Right Certificates had not ceased to be such officer
of the Company; and any Right Certificate may be signed on behalf of the Company
by any person who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Company to sign such Right
Certificate, although at the date of the execution of this Rights Agreement any
such person was not such an officer.

                  Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its principal office, books for registration and transfer
of the Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of the Right Certificates, the number of
Rights evidenced on its face by each of the Right Certificates and the date of
each of the Right Certificates.

                                      -7-
<PAGE>

                  SECTION 6. TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF
RIGHT CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES.
Subject to the provisions of Section 14 hereof, at any time after the close of
business on the Distribution Date, and at or prior to the close of business on
the earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates,
entitling the registered holder to purchase a like number of one one-hundredths
of a Preferred Share as the Right Certificate or Right Certificates surrendered
then entitled such holder to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Right Certificate or Right
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

                  Upon receipt by the Rights Agent of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of a Right
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, reimbursement to the Company and the
Rights Agent of all reasonable expenses incidental thereto, and upon surrender
to the Rights Agent and cancellation of the Right Certificate if mutilated, the
Rights Agent will make and deliver a new Right Certificate of like tenor to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

                  SECTION 7. EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE
OF RIGHTS. (a) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein) in whole or in
part at any time after the Distribution Date upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side 


                                      -8-
<PAGE>

thereof duly executed, to the Rights Agent at the principal office of the Rights
Agent, together with payment of the Purchase Price for each one one-hundredth of
a Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the close of business on September 30, 2008 (the "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 hereof (the "Redemption Date"), or (iii) the time at which such
Rights are exchanged as provided in Section 24 hereof.

                  (b) The Purchase Price for each one one-hundredth of a
Preferred Share purchasable pursuant to the exercise of a Right shall initially
be $160, and shall be subject to adjustment from time to time as provided in
Section 11 or 13 hereof and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

                  (c) Upon receipt of a Right Certificate representing
exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Purchase Price for the shares to be purchased and
an amount equal to any applicable transfer tax required to be paid by the holder
of such Right Certificate in accordance with Section 9 hereof by certified
check, cashier's check or money order payable to the order of the Company, the
Rights Agent shall thereupon promptly (i) (A) requisition from any transfer
agent of the Preferred Shares certificates for the number of Preferred Shares to
be purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) requisition from the depositary agent
depositary receipts representing such number of one one-hundredths of a
Preferred Share as are to be purchased (in which case the Preferred Shares
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company hereby directs the depositary agent to comply
with such request, (ii) when appropriate, requisition from the Company the
amount of cash to be paid in lieu of issuance of fractional shares in accordance
with Section 14 hereof, (iii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Right Certificate, registered in such name or names as may be
designated by such holder and (iv) when appropriate, after receipt, deliver such
cash to or upon the order of the registered holder of such Right Certificate.

                                      -9-
<PAGE>

                  (d) In case the registered holder of any Right Certificate
shall exercise less than all the Rights evidenced thereby, a new Right
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to the registered holder of such Right
Certificate or to such holder's duly authorized assigns, subject to the
provisions of Section 14 hereof.

                  SECTION 8. CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES.
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in canceled
form, or, if surrendered to the Rights Agent, shall be canceled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Rights Agreement. The Company shall deliver to
the Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
a certificate of cancellation thereof to the Company, and destroy such canceled
Right Certificates in accordance with applicable laws and regulations.

                  SECTION 9. AVAILABILITY OF PREFERRED SHARES. The Company
covenants and agrees that it will cause to be reserved and kept available out of
its authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury, the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance with Section 7. The
Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares delivered upon exercise of Rights
shall, at the time of delivery of the certificates for such Preferred Shares
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares.

                  The Company further covenants and agrees that it will pay when
due and payable any and all federal and state transfer taxes and charges which
may be payable in respect of the issuance or delivery of the Right Certificates
or of any Preferred Shares upon the exercise of Rights. The Company shall not,
however, be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Right Certificates to a person other than, or the

                                      -10-
<PAGE>

issuance or delivery of certificates or depositary receipts for the Preferred
Shares in a name other than that of, the registered holder of the Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depositary receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such tax being
payable by the holder of such Right Certificate at the time of surrender) or
until it has been established to the Company's reasonable satisfaction that no
such tax is due.

                  SECTION 10. PREFERRED SHARES RECORD DATE. Each person in whose
name any certificate for Preferred Shares is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of the
Preferred Shares represented thereby on, and such certificate shall be dated,
the date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Shares transfer books of the Company
are closed, such person shall be deemed to have become the record holder of such
shares on, and such certificate shall be dated, the next succeeding Business Day
on which the Preferred Shares transfer books of the Company are open. Prior to
the exercise of the Rights evidenced thereby, the holder of a Right Certificate
shall not be entitled to any rights of a holder of Preferred Shares for which
the Rights shall be exercisable, including, without limitation, the right to
vote, to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of
the Company, except as provided herein.

                  SECTION 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR
NUMBER OF RIGHTS. The Purchase Price, the number of Preferred Shares covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

                  (a) (i) In the event the Company shall at any time after the
date of this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a 


                                      -11-
<PAGE>

reclassification of the Preferred Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), except as otherwise provided in this Section 11(a),
the Purchase Price in effect at the time of the record date for such dividend or
of the effective date of such subdivision, combination or reclassification, and
the number and kind of shares of capital stock issuable on such date, shall be
proportionately adjusted so that the holder of any Right exercised after such
time shall be entitled to receive the aggregate number and kind of shares of
capital stock which, if such Right had been exercised immediately prior to such
date and at a time when the Preferred Shares transfer books of the Company were
open, such holder would have owned upon such exercise and been entitled to
receive by virtue of such dividend, subdivision, combination or
reclassification; provided, however, that in no event shall the consideration to
be paid upon the exercise of one Right be less than the aggregate par value of
the shares of capital stock of the Company issuable upon exercise of one Right.

                  (ii) Subject to Section 24 of this Agreement, in the event any
Person becomes an Acquiring Person, each holder of a Right shall thereafter have
a right to receive, upon exercise thereof at a price equal to the then current
Purchase Price multiplied by the number of one one-hundredths of a Preferred
Share for which a Right is then exercisable, in accordance with the terms of
this Agreement, such number of Common Shares of the Company as shall equal the
result obtained by (x) multiplying the then current Purchase Price by the number
of one one-hundredths of a Preferred Share for which a Right is then exercisable
and dividing that product by (y) 50% of the then current per share market price
of the Company's Common Stock (determined pursuant to Section 11(d) hereof) on
the date of the occurrence of such event. In the event that any Person shall
become an Acquiring Person and the Rights shall then be outstanding, the Company
shall not take any action which would eliminate or diminish the benefits
intended to be afforded by the Rights.

                  From and after the occurrence of such event, any Rights that
are or were acquired or beneficially owned by any Acquiring Person (or any
Associate or Affiliate of such Acquiring Person) shall be void and any holder of
such Rights shall thereafter have no right to exercise such Rights under any
provision of this Agreement. No Right Certificate shall be issued pursuant to

                                      -12-
<PAGE>

Section 3 that represents Rights beneficially owned by an Acquiring Person whose
Rights would be void pursuant to the preceding sentence or any Associate or
Affiliate thereof; no Right Certificate shall be issued at any time upon the
transfer of any Rights to an Acquiring Person whose Rights would be void
pursuant to the preceding sentence or any Associate or Affiliate thereof or to
any nominee of such Acquiring Person, Associate or Affiliate; and any Right
Certificate delivered to the Rights Agent for transfer to an Acquiring Person
whose Rights would be void pursuant to the preceding sentence shall be
cancelled.

                  (iii) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit the
exercise in full of the Rights in accordance with the foregoing subparagraph
(ii), the Company shall take all such action as may be necessary to authorize
additional Common Shares for issuance upon exercise of the Rights. In the event
the Company shall, after good faith effort, be unable to take all such action as
may be necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exercise
of a Right, one one-hundredth of a Preferred Share or a number of other
securities or fraction thereof of the Company such that the current per share
market price of one such security multiplied by such number or fraction is equal
to the current per share market price of one Common Share as of the date of
issuance of such securities or fraction thereof.

                  (b) In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of Preferred Shares
entitling them (for a period expiring within 45 calendar days after such record
date) to subscribe for or purchase Preferred Shares (or shares having the same
rights, privileges and preferences as the Preferred Shares ("equivalent
preferred shares")) or securities convertible into Preferred Shares or
equivalent preferred shares at a price per Preferred Share or equivalent
preferred share (or having a conversion price per share, if a security
convertible into Preferred Shares or equivalent preferred shares) less than the
then current per share market price of the Preferred Shares (as defined in
Section 11(d)) on such record date, the Purchase Price to be in effect after
such record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the number of Preferred Shares outstanding on such record date plus 


                                      -13-
<PAGE>

the number of Preferred Shares which the aggregate offering price of the total
number of Preferred Shares and/or equivalent preferred shares so to be offered
(and/or the aggregate initial conversion price of the convertible securities so
to be offered) would purchase at such current market price and the denominator
of which shall be the number of Preferred Shares outstanding on such record date
plus the number of additional Preferred Shares and/or equivalent preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible); provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right. In case such subscription price may be paid
in a consideration part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent. Preferred Shares owned by or held for the account
of the Company shall not be deemed outstanding for the purpose of any such
computation. Such adjustment shall be made successively whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

                  (c) In case the Company shall fix a record date for the making
of a distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b) hereof), the Purchase Price to be in effect after such
record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the then current per share market price of the Preferred Shares on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the 


                                      -14-
<PAGE>

denominator of which shall be such current per share market price of the
Preferred Shares; provided, however, that in no event shall the consideration to
be paid upon the exercise of one Right be less than the aggregate par value of
the shares of capital stock of the Company to be issued upon exercise of one
Right. Such adjustments shall be made successively whenever such a record date
is fixed; and in the event that such distribution is not so made, the Purchase
Price shall again be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

                  (d) (i) For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the 30 consecutive Trading
Days (as such term is hereinafter defined) immediately prior to such date;
provided, however, that in the event that the current per share market price of
the Security is determined during a period following the announcement by the
issuer of such Security of (A) a dividend or distribution on such Security
payable in shares of such Security or securities convertible into such shares,
or (B) any subdivision, combination or reclassification of such Security and
prior to the expiration of 30 Trading Days after the ex-dividend date for such
dividend or distribution, or the record date for such subdivision, combination
or reclassification, then, and in each such case, the current per share market
price shall be appropriately adjusted to reflect the current market price per
share equivalent of such Security. The closing price for each day shall be the
last sale price, regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Security is not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Security is listed or admitted to trading or, if the Security is
not listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotations System ("NASDAQ") or such other
system 


                                      -15-
<PAGE>

then in use, or, if on any such date the Security is not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Security selected by the Board
of Directors of the Company. The term "Trading Day" shall mean a day on which
the principal national securities exchange on which the Security is listed or
admitted to trading is open for the transaction of business or, if the Security
is not listed or admitted to trading on any national securities exchange, a
Business Day.

                  (ii) For the purpose of any computation hereunder, the
"current per share market price" of the Preferred Shares shall be determined in
accordance with the method set forth in Section 11(d)(i). If the Preferred
Shares are not publicly traded, the "current per share market price" of the
Preferred Shares shall be conclusively deemed to be the current per share market
price of the Common Shares as determined pursuant to Section 11(d)(i)
(appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof), multiplied by one hundred. If
neither the Common Shares nor the Preferred Shares are publicly held or so
listed or traded, "current per share market price" shall mean the fair value per
share as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent.

                  (e) No adjustment in the Purchase Price shall be required
unless such adjustment would require an increase or decrease of at least 1% in
the Purchase Price; provided, however, that any adjustments which by reason of
this Section 11(e) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Section 11 shall be made to the nearest cent or to the nearest one one-millionth
of a Preferred Share or one ten-thousandth of any other share or security as the
case may be. Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which requires such
adjustment or (ii) the date of the expiration of the right to exercise any
Rights.

                  (f) If as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Company other than Preferred
Shares, thereafter the number of such other shares so 


                                      -16-
<PAGE>

receivable upon exercise of any Right shall be subject to adjustment from time
to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Preferred Shares contained in Section 11(a)
through (c), inclusive, and the provisions of Sections 7, 9, 10 and 13 with
respect to the Preferred Shares shall apply on like terms to any such other
shares.

                  (g) All Rights originally issued by the Company subsequent to
any adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred Share purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                  (h) Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase Price as a
result of the calculations made in Sections 11(b) and (c), each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
one one-hundredths of a Preferred Share (calculated to the nearest one
one-millionth of a Preferred Share) obtained by (i) multiplying (x) the number
of one one-hundredths of a share covered by a Right immediately prior to this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

                  (i) The Company may elect on or after the date of any
adjustment of the Purchase Price to adjust the number of Rights, in substitution
for any adjustment in the number of one one-hundredths of a Preferred Share
purchasable upon the exercise of a Right. Each of the Rights outstanding after
such adjustment of the number of Rights shall be exercisable for the number of
one one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement and shall promptly provide written
notice to the Rights Agent 


                                      -17-
<PAGE>

of its election to adjust the number of Rights, indicating the record date for
the adjustment, and, if known at the time, the amount of the adjustment to be
made. This record date may be the date on which the Purchase Price is adjusted
or any day thereafter, but, if the Right Certificates have been issued, shall be
at least 10 days later than the date of the public announcement. If Right
Certificates have been issued, upon each adjustment of the number of Rights
pursuant to this Section 11(i), the Company shall, as promptly as practicable,
cause to be distributed to holders of record of Right Certificates on such
record date Right Certificates evidencing, subject to Section 14 hereof, the
additional Rights to which such holders shall be entitled as a result of such
adjustment, or, at the option of the Company, shall cause to be distributed to
such holders of record in substitution and replacement for the Right
Certificates held by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Right Certificates evidencing
all the Rights to which such holders shall be entitled after such adjustment.
Right Certificates so to be distributed shall be issued, executed and
countersigned in the manner provided for herein and shall be registered in the
names of the holders of record of Right Certificates on the record date
specified in the public announcement.

                  (j) Irrespective of any adjustment or change in the Purchase
Price or the number of one one-hundredths of a Preferred Share issuable upon the
exercise of the Rights, the Right Certificates theretofore and thereafter issued
may continue to express the Purchase Price and the number of one one-hundredths
of a Preferred Share which were expressed in the initial Right Certificates
issued hereunder.

                  (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below one one-hundredth of the then par value, if
any, of the Preferred Shares issuable upon exercise of the Rights, the Company
shall take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price.

                  (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised 


                                      -18-
<PAGE>

after such record date of the Preferred Shares and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise on the basis of the Purchase Price in effect
prior to such adjustment; provided, however, that the Company shall deliver to
such holder a due bill or other appropriate instrument evidencing such holder's
right to receive such additional shares upon the occurrence of the event
requiring such adjustment.

                  (m) Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such reductions in the
Purchase Price, in addition to those adjustments expressly required by this
Section 11, as and to the extent that it in its sole discretion shall determine
to be advisable in order that any consolidation or subdivision of the Preferred
Shares, issuance wholly for cash of any Preferred Shares at less than the
current market price, issuance wholly for cash of Preferred Shares or securities
which by their terms are convertible into or exchangeable for Preferred Shares,
dividends on Preferred Shares payable in Preferred Shares or issuance of rights,
options or warrants referred to hereinabove in Section 11(b), hereafter made by
the Company to holders of its Preferred Shares shall not be taxable to such
stockholders.

                  (n) In the event that at any time after the date of this
Agreement and prior to the Distribution Date, the Company shall (i) declare or
pay any dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in any such case (A) the
number of one one-hundredths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-hundredths of a Preferred Share so purchasable immediately prior to
such event by a fraction, the numerator of which is the number of Common Shares
outstanding immediately before such event and the denominator of which is the
number of Common Shares outstanding immediately after such event, and (B) each
Common Share outstanding immediately after such event shall have issued with
respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments
provided for in this Section 11(n) shall be made 


                                      -19-
<PAGE>

successively whenever such a dividend is declared or paid or such a subdivision,
combination or consolidation is effected.

                  SECTION 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER
OF SHARES. Whenever an adjustment is made as provided in Section 11 or 13
hereof, the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Right Certificate in accordance with Section
25 hereof.

                  SECTION 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF
ASSETS OR EARNING POWER. In the event, directly or indirectly, at any time after
a Person has become an Acquiring Person, (a) the Company shall consolidate with,
or merge with and into, any other Person, (b) any Person shall consolidate with
the Company, or merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person (or the Company) or cash or any
other property, or (c) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person other than the Company or one or more of its wholly-owned
Subsidiaries, then, and in each such case, proper provision shall be made so
that (i) each holder of a Right (except as otherwise provided herein) shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to the then current Purchase Price multiplied by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of Common Shares of such other Person (including the Company as
successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-hundredths of a Preferred Share for which a Right is then exercisable and
dividing that product by (B) 50% of the then current per share market price of
the Common Shares of such other Person (determined pursuant to Section 11(d)
hereof) on the date of consummation of such 


                                      -20-
<PAGE>

consolidation, merger, sale or transfer; (ii) the issuer of such Common Shares
shall thereafter be liable for, and shall assume, by virtue of such
consolidation, merger, sale or transfer, all the obligations and duties of the
Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be
deemed to refer to such issuer; and (iv) such issuer shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
Common Shares in accordance with Section 9 hereof) in connection with such
consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to the
Common Shares thereafter deliverable upon the exercise of the Rights. The
Company shall not consummate any such consolidation, merger, sale or transfer
unless prior thereto the Company and such issuer shall have executed and
delivered to the Rights Agent a supplemental agreement so providing. The Company
shall not enter into any transaction of the kind referred to in this Section 13
if at the time of such transaction there are any rights, warrants, instruments
or securities outstanding or any agreements or arrangements which, as a result
of the consummation of such transaction, would eliminate or substantially
diminish the benefits intended to be afforded by the Rights. The provisions of
this Section 13 shall similarly apply to successive mergers or consolidations or
sales or other transfers.

                  SECTION 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES. (a) The
Company shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right. For the purposes of this Section 14(a), the current market value of a
whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable. The closing price for any day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of
the closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange or, if the Rights
are not listed or admitted to trading on the New York Stock Exchange, as
reported in the principal consolidated transaction reporting system with respect
to securities 


                                      -21-
<PAGE>

listed on the principal national securities exchange on which the Rights are
listed or admitted to trading or, if the Rights are not listed or admitted to
trading on any national securities exchange, the last quoted price or, if not so
quoted, the average of the high bid and low asked prices in the over-the-counter
market, as reported by NASDAQ or such other system then in use or, if on any
such date the Rights are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Rights selected by the Board of Directors of the Company. If on
any such date no such market maker is making a market in the Rights, the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute
certificates which evidence fractional Preferred Shares (other than fractions
which are integral multiples of one one-hundredth of a Preferred Share).
Fractions of Preferred Shares in integral multiples of one one-hundredth of a
Preferred Share may, at the election of the Company, be evidenced by depositary
receipts, pursuant to an appropriate agreement between the Company and a
depositary selected by it; provided, that such agreement shall provide that the
holders of such depositary receipts shall have all the rights, privileges and
preferences to which they are entitled as beneficial owners of the Preferred
Shares represented by such depositary receipts. In lieu of fractional Preferred
Shares that are not integral multiples of one one-hundredth of a Preferred
Share, the Company shall pay to the registered holders of Right Certificates at
the time such Rights are exercised as herein provided an amount in cash equal to
the same fraction of the current market value of one Preferred Share. For the
purposes of this Section 14(b), the current market value of a Preferred Share
shall be the closing price of a Preferred Share (as determined pursuant to the
second sentence of Section 11(d)(i) hereof) for the Trading Day immediately
prior to the date of such exercise.

                  (c) The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise of a Right (except as provided above).

<PAGE>

                  SECTION 15. RIGHTS OF ACTION. All rights of action in respect
of this Agreement, excepting the rights of action given to the Rights Agent
under Section 18 hereof, are vested in the respective registered holders of the
Right Certificates (and, prior to the Distribution Date, the registered holders
of the Common Shares); and any registered holder of any Right Certificate (or,
prior to the Distribution Date, of the Common Shares), without the consent of
the Rights Agent or of the holder of any other Right Certificate (or, prior to
the Distribution Date, of the Common Shares), may, in such holder's own behalf
and for such holder's own benefit, enforce, and may institute and maintain any
suit, action or proceeding against the Company to enforce, or otherwise act in
respect of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of
any Person subject to, this Agreement.

                  SECTION 16. AGREEMENT OF RIGHT HOLDERS. Every holder of a
Right, by accepting the same, consents and agrees with the Company and the
Rights Agent and with every other holder of a Right that:

                  (a) prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common Shares;

                  (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the principal office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

                  (c) the Company and the Rights Agent may deem and treat the
person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Shares certificate) is recorded on the books for
registration and transfer of the Rights, or the Common Shares, as the case may
be, as the absolute owner thereof and of the Rights evidenced thereby
(notwithstanding any notations of ownership or writing on the Right Certificate
or the associated 


                                      -23-
<PAGE>

Common Shares certificate made by anyone other than the Company or the Rights
Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent
shall be affected by any notice to the contrary.

                  (d) notwithstanding anything in this Agreement to the
contrary, neither the Company nor the Rights Agent shall have any liability to
any holder of a Right or other Person as a result of its inability to perform
any of its obligations under this Agreement by reason of any preliminary or
permanent injunction or other order, decree or ruling issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency
or commission, or any statute, rule, regulation or executive order promulgated
or enacted by any governmental authority, prohibiting or otherwise restraining
performance of such obligations; provided, however, the Company must use its
reasonable best efforts to have any such order, decree or ruling lifted or
otherwise overturned as soon as possible.

                  SECTION 17. RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a holder of Common Shares of the
Company or any right to vote for the election of directors or upon any matter
submitted to holders of Common Shares at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting holders of Common Shares (except as provided in Section
25 hereof), or to receive dividends or subscription rights, or otherwise, until
the Right or Rights evidenced by such Right Certificate shall have been
exercised in accordance with the provisions hereof.

                  SECTION 18. CONCERNING THE RIGHTS AGENT. The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Agreement and the exercise 


                                      -24-
<PAGE>

and performance of its duties hereunder. The Company also agrees to indemnify
the Rights Agent including its members, directors, officers, owners, employees
and agents, for, and to hold it harmless against, any loss, liability, or
expense, incurred without negligence, bad faith or willful misconduct on the
part of the Rights Agent, for anything done or omitted by the Rights Agent in
connection with the acceptance and administration of this Agreement, including
the costs and expenses of defending against any claim of liability in the
premises. The indemnity provided herein shall survive the expiration of the
Rights and the termination of this Agreement.

                  The Rights Agent shall be protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it in
connection with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Shares or Common Shares or for
other securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified, guaranteed or
acknowledged, by the proper person or persons, or otherwise upon the advice of
counsel as set forth in Section 20 hereof.

                  SECTION 19. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF
RIGHTS AGENT. Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the stock transfer or corporate trust powers of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto; provided, that such corporation would be
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement, any of the Right Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the 


                                      -25-
<PAGE>

name of the predecessor Rights Agent or in the name of the successor Rights
Agent; and in all such cases such Right Certificates shall have the full force
provided in the Right Certificates and in this Agreement.

                  In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates so countersigned; and in
case at that time any of the Right Certificates shall not have been
countersigned, the Rights Agent may countersign such Right Certificates either
in its prior name or in its changed name; and in all such cases such Right
Certificates shall have the full force provided in the Right Certificates and in
this Agreement.

                  SECTION 20. DUTIES OF RIGHTS AGENT. The Rights Agent
undertakes the specific duties and obligations imposed by this Agreement, and no
implied duties or obligations shall be read into this Agreement against the
Rights Agent, upon the following terms and conditions, by all of which the
Company and the holders of Right Certificates, by their acceptance thereof,
shall be bound:

                  (a) The Rights Agent may consult with legal counsel (who may
be legal counsel for the Company or the Rights Agent), and the opinion of such
counsel shall be full and complete authorization and protection to the Rights
Agent as to any action taken or omitted by it in good faith and in accordance
with such opinion.

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking or suffering any
action hereunder, such fact or matter (unless other evidence in respect thereof
be herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President, any Vice President, the Treasurer or the
Secretary of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Agreement in reliance upon such
certificate.

                                      -26-
<PAGE>

                  (c) The Rights Agent shall be liable hereunder to the Company
and any other Person only for its own negligence, bad faith or willful
misconduct.

                  (d) The Rights Agent shall not be liable for or by reason of
any of the statements of fact or recitals contained in this Agreement or in the
Right Certificates (except its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

                  (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Right Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or any
adjustment in the terms of the Rights (including the manner, method or amount
thereof) provided for in Section 3, 11, 13, 23 or 24, or the ascertaining of the
existence of facts that would require any such change or adjustment (except with
respect to the exercise of Rights evidenced by Right Certificates after actual
notice that such change or adjustment is required); nor shall it by any act
hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant to
this Agreement or any Right Certificate or as to whether any Preferred Shares
will, when issued, be validly authorized and issued, fully paid and
nonassessable.

                  (f) The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
any one of the Chairman of the Board, the Chief Executive Officer, the
President, any Vice President, the Secretary or the Treasurer of the Company,
and to apply to such officers for advice or instructions in connection 


                                      -27-
<PAGE>

with its duties, and it shall not be liable for any action taken or suffered by
it in good faith in accordance with instructions of any such officer or for any
delay in acting while waiting for those instructions.

                  (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.

                  (i) The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys or agents, and the Rights Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company resulting from any such
act, default, neglect or misconduct, provided reasonable care was exercised in
the selection and continued employment thereof.

                  (j) The Rights Agent shall have no responsibility to the
Company, any holders of Rights or any holders of Common Shares for interest or
earnings on any monies held by the Rights Agent pursuant to this Agreement.

                  (k) The Rights Agent shall not be required to take notice or
be deemed to have notice of any event or condition hereunder, including, but not
limited to, a Distribution Date, a Redemption Date, any adjustment of the
Purchase Price or the Common Shares, the existence of an Acquiring Person or a
Beneficial Owner or any other event or condition that may require action by the
Rights Agent, unless the Rights Agent shall be specifically notified in writing
of such event or condition by the Company, and all notices or other requirements
required by this Agreement to be delivered to the Rights Agent must, in order to
be effective, be received at the principal office of the Rights Agent, and in
the absence of such notice so delivered, the Rights Agent may conclusively
assume no such event or condition exists.

                  SECTION 21. CHANGE OF RIGHTS AGENT. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Right Certificate
(who shall, with such notice, submit his Right Certificate for inspection by the
Company), then the registered holder of any Right Certificate or the Rights
Agent may apply to any court of competent jurisdiction for the appointment of a
new Rights Agent. Any successor Rights Agent, whether appointed by the Company
or by such a court, shall be a corporation organized and doing business under
the laws of the United States or of the State of Missouri (or of any other state
of the United States so long as such corporation is authorized to do business as
a banking institution in the State of Missouri), in good standing, having an
office in the State of Missouri, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject to supervision or
examination by federal or state authority and which has at the time of its
appointment as Rights Agent a combined capital and surplus of at least $50
million. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed and the rights and obligations
of the predecessor Rights Agent hereunder shall cease and terminate; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Shares or Preferred Shares, and mail a 


                                      -29-
<PAGE>

notice thereof in writing to the registered holders of the Right Certificates.
Failure to give any notice provided for in this Section 21, however, or any
defect therein, shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent, as
the case may be.

                  SECTION 22. ISSUANCE OF NEW RIGHT CERTIFICATES.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Agreement.

                  SECTION 23. REDEMPTION. (a) The Board of Directors of the
Company may, at its option, at any time prior to such time as any Person becomes
an Acquiring Person, redeem all but not less than all the then outstanding
Rights at a redemption price of $.01 per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such redemption price being hereinafter referred to as the
"Redemption Price"). The redemption of the Rights by the Board of Directors may
be made effective at such time, on such basis and with such conditions as the
Board of Directors in its sole discretion may establish.

                  (b) Immediately upon the effectiveness of the action of the
Board of Directors of the Company ordering the redemption of the Rights pursuant
to paragraph (a) of this Section 23, and without any further action and without
any notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price.
The Company shall promptly give public notice of any such redemption; provided,
however, that the failure to give, or any defect in, any such notice shall not
affect the validity of such redemption. Within 10 days after the effectiveness
of such action of the Board of Directors ordering the redemption of the Rights,
the Company shall mail a notice of redemption to all the holders of the then
outstanding Rights at their last addresses as they appear upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the transfer 


                                      -30-
<PAGE>

agent for the Common Shares. Any notice which is mailed in the manner herein
provided shall be deemed given, whether or not the holder receives the notice.
Each such notice of redemption will state the method by which the payment of the
Redemption Price will be made. Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23 or in
Section 24 hereof, and other than in connection with the purchase of Common
Shares prior to the Distribution Date.

                  SECTION 24. EXCHANGE. (a) The Board of Directors of the
Company may, at its option, at any time after any Person becomes an Acquiring
Person, exchange all or part of the then outstanding and exercisable Rights
(which shall not include Rights that have become void pursuant to the provisions
of Section 11(a)(ii) hereof) for Common Shares or Preferred Shares at an
exchange ratio of one Common Share or one-hundredth of a Preferred Share per
Right (such exchange ratio being hereinafter referred to as the "Exchange
Ratio"). Notwithstanding the foregoing, the Board of Directors shall not be
empowered to effect such exchange at any time after any Person (other than an
Exempt Person), together with all Affiliates and Associates of such Person,
becomes the Beneficial Owner of 50% or more of the Common Shares then
outstanding.

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the exchange of any Rights pursuant to paragraph (a) of
this Section 24 and without any further action and without any notice, the right
to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of Common Shares or
Preferred Shares equal to the number of such Rights held by such holder
multiplied by the Exchange Ratio. The Company shall promptly give public notice
of any such exchange; provided, however, that the failure to give, or any defect
in, such notice shall not affect the validity of such exchange. The Company
promptly shall mail a notice of any such exchange to all of the holders of such
Rights at their last addresses as they appear upon the registry books of the
Rights Agent. Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such notice of
exchange will state the method by which the exchange of the Common Shares or
Preferred Shares, as the case may be, 


                                      -31-
<PAGE>

for Rights will be effected and, in the event of any partial exchange, the
number of Rights which will be exchanged. Any partial exchange shall be effected
pro rata based on the number of Rights (other than Rights which have become void
pursuant to the provisions of Section 11(a)(ii) hereof) held by each holder of
Rights.

                  (c) In the event that there shall not be sufficient Common
Shares or Preferred Shares issued but not outstanding or authorized but unissued
to permit any exchange of Rights as contemplated in accordance with this Section
24, the Company shall take all such action as may be necessary to authorize
additional Common Shares or Preferred Shares for issuance upon exchange of the
Rights. In the event the Company shall, after good faith effort, be unable to
take all such action as may be necessary to authorize such additional Common
Shares or Preferred Shares, the Company shall substitute, for each Common Share
or Preferred Share that would otherwise be issuable upon exchange of a Right, a
number of securities or fraction thereof of the Company such that the current
per share market price of one such security multiplied by such number or
fraction is equal to the current per share market price of one Common Share as
of the date of issuance of such securities or fraction thereof.

                  SECTION 25. NOTICE OF CERTAIN EVENTS. (a) In case the Company
shall propose (i) to pay any dividend payable in stock of any class to the
holders of its Preferred Shares or to make any other distribution to the holders
of its Preferred Shares (other than a regular quarterly cash dividend), (ii) to
offer to the holders of its Preferred Shares rights or warrants to subscribe for
or to purchase any additional Preferred Shares or shares of stock of any class
or any other securities, rights or options, (iii) to effect any reclassification
of its Preferred Shares (other than a reclassification involving only the
subdivision of outstanding Preferred Shares), (iv) to effect any consolidation
or merger into or with, or to effect any sale or other transfer (or to permit
one or more of its Subsidiaries to effect any sale or other transfer), in one or
more transactions, of 50% or more of the assets or earning power of the Company
and its Subsidiaries (taken as a whole) to, any other Person, (v) to effect the
liquidation, dissolution or winding up of the Company, or (vi) to declare or pay
any dividend on the Common Shares payable in Common Shares or to effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares),
then, in each such case, the 


                                      -32-
<PAGE>

Company shall give to each holder of a Right Certificate, as promptly as
reasonably practicable, in accordance with Section 26 hereof, a notice of such
proposed action, which shall specify the record date for the purposes of such
stock dividend, or distribution of rights or warrants, or the date on which such
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution, or winding up is to take place and the date of participation
therein by the holders of the Common Shares and/or Preferred Shares, if any such
date is to be fixed.

                  (b) In case the event set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate, in accordance with Section 26 hereof, a
notice of the occurrence of such event, which notice shall describe such event
and the consequences of such event to holders of Rights under Section 11(a)(ii)
hereof.

                  SECTION 26. NOTICES. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by

shall be sufficiently given or made if sent by first-class mail, postage
prepaid, addressed to such holder at the address of such holder as shown on the
registry books for the Rights Contributors of the Company, provided, however, if
such notice is given prior to the Distribution Date, such notice shall be given
to the holders of Common Shares on the registry books of the Company maintained
by the transfer agent for the Common Shares.

                  SECTION 27. SUPPLEMENTS AND AMENDMENTS. The Company may from

holders of Right Certificates in order to cure any ambiguity, to correct or

with any other provisions herein, or to make any other provisions with respect
to the Rights which the Company may deem necessary or desirable, any such
supplement or amendment to be evidenced by a writing signed by the Company and
the Rights Agent; provided, however, that from and after such time as any Person
becomes an Acquiring Person, this Agreement shall not be amended in any manner
which would adversely affect the interests of the holders of Rights. Without
limiting the foregoing, the Company may at any time prior to such time as any
Person becomes an Acquiring Person amend this Agreement to lower the thresholds
set forth in Sections 1(a) and 3(a) to not less than the greater of (i) the sum
of .001% and the largest percentage of the outstanding Common Shares then known
by the Company to be beneficially owned by any Person (other than an Exempt
Person) and (ii) 10%.

                  SECTION 28. SUCCESSORS. All the covenants and provisions of

bind and inure to the benefit of their respective successors and assigns
hereunder.

                  SECTION 29. BENEFITS OF THIS AGREEMENT. Nothing in this
Agreement shall be construed to give to any person or corporation other than the
Company, the Rights Agent and the registered holders of the Right Certificates
(and, prior to the Distribution Date, the Common Shares) any legal or equitable
right, remedy or claim under this Agreement; but this Agreement 


                                      -34-
<PAGE>

shall be for the sole and exclusive benefit of the Company, the Rights Agent and
the registered holders of the Right Certificates (and, prior to the Distribution
Date, the Common Shares).

                  SECTION 30. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

any number of counterparts and each of such counterparts shall for all purposes

                        --------------------------------

                  Butler Manufacturing Company, a corporation organized and
existing under the General Corporation Law of the State of Delaware (hereinafter
called the "Corporation"), hereby certifies that the following resolution was
adopted by the Board of Directors of the Corporation as required by Section 151
of the General Corporation Law at a meeting duly called and held on September
15, 1988:

                  RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, the Board of Directors hereby creates a series of Preferred
Stock, without par value (the "Preferred Stock"), of the Corporation and hereby
states the designation and number of shares, and fixes the relative rights,
preferences, and limitations thereof as follows:

                  Series A, Class 1 Preferred Stock:

                  Designation and Amount. The shares of such series shall be
designated as "Series A Class 1 Preferred Stock" (the "Series A Preferred
Stock") and the number of shares constituting the Series A Preferred Stock shall
be 75,000. Such number of shares may be increased or decreased by resolution of
the Board of Directors; provided, that no decrease shall reduce the number of
shares of Series A Preferred Stock to a number less than the number of shares
then outstanding plus the number of shares reserved for issuance upon the
exercise of outstanding options, rights or warrants or upon the conversion of
any outstanding securities issued by the Corporation convertible into Series A
Preferred Stock.

                  Dividends and Distributions.

                  Subject to the rights of the holders of any shares of any
         series of Preferred Stock (or any similar stock) ranking prior and
         superior to the Series A Preferred Stock with 

                                      A-3
<PAGE>

         respect to dividends, the holders of shares of Series A Preferred
         Stock, in preference to the holders of Common Stock, without par value
         (the "Common Stock"), of the Corporation, and of any other junior
         stock, shall be entitled to receive, when, as and if declared by the
         Board of Directors out of funds legally available for the purpose,
         quarterly dividends payable in cash on the first day of March, June,
         September and December in each year (each such date being referred to
         herein as a "Quarterly Dividend Payment Date"), commencing on the first
         Quarterly Dividend Payment Date after the first issuance of a share or
         fraction of a share of Series A Preferred Stock, in an amount per share
         (rounded to the nearest cent) equal to the greater of (a) $1 or (b)
         subject to the provision for adjustment hereinafter set forth, 100
         times the aggregate per share amount of all cash dividends, and 100
         times the aggregate per share amount (payable in kind) of all non-cash
         dividends or other distributions, other than a dividend payable in
         shares of Common Stock or a subdivision of the outstanding shares of
         Common Stock (by reclassification or otherwise), declared on the Common
         Stock since the immediately preceding Quarterly Dividend Payment Date
         or, with respect to the first Quarterly Dividend Payment Date, since
         the first issuance of any share or fraction of a share of Series A
         Preferred Stock. In the event the Corporation shall at any time declare
         or pay any dividend on the Common Stock payable in shares of Common
         Stock, or effect a subdivision or combination or consolidation of the
         outstanding shares of Common Stock (by reclassification or otherwise
         than by payment of a dividend in shares of Common Stock) into a greater
         or lesser number of shares of Common Stock, then in each such case the
         amount to which holders of shares of Series A Preferred Stock were
         entitled immediately prior to such event under clause (b) of the
         preceding sentence shall be adjusted by multiplying such amount by a
         fraction, the numerator of which is the number of shares of Common
         Stock outstanding immediately after such event and the denominator of
         which is the number of shares of Common Stock that were outstanding
         immediately prior to such event.

                  The Corporation shall declare a dividend or distribution on
         the Series A Preferred Stock as provided in paragraph (A) of this
         Section immediately after it declares a dividend or distribution on the
         Common Stock (other than a dividend payable in shares of Common Stock);
         provided that, in the event no dividend or distribution shall have been
         declared on the Common Stock during the period between any Quarterly
         Dividend Payment Date and the next subsequent Quarterly Dividend
         Payment Date, a dividend of $1 per share on the Series A Preferred
         Stock shall nevertheless be payable on such subsequent Quarterly
         Dividend Payment Date.

                  Dividends shall begin to accrue and be cumulative on
         outstanding shares of Series A Preferred Stock from the Quarterly
         Dividend Payment Date next preceding the date of issue of such shares,
         unless the date of issue of such shares is prior to the record date for
         the first Quarterly Dividend Payment Date, in which case dividends on
         such shares shall begin to accrue from the date of issue of such
         shares, or unless the date of issue is a Quarterly Dividend Payment
         Date or is a date after the record date for the determination of
         holders of shares of Series A Preferred Stock entitled to receive a
         quarterly dividend and before such Quarterly Dividend Payment Date, in
         either of which events such 

                                      A-4
<PAGE>

         dividends shall begin to accrue and be cumulative from such Quarterly
         Dividend Payment Date. Accrued but unpaid dividends shall not bear
         interest. Dividends paid on the shares of Series A Preferred Stock in
         an amount less than the total amount of such dividends at the time
         accrued and payable on such shares shall be allocated pro rata on a
         share-by-share basis among all such shares at the time outstanding. The
         Board of Directors may fix a record date for the determination of
         holders of shares of Series A Preferred Stock entitled to receive
         payment of a dividend or distribution declared thereon, which record
         date shall be not more than 60 days prior to the date fixed for the
         payment thereof.

                  Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                  Subject to the provision for adjustment hereinafter set forth,
         each share of Series A Preferred Stock shall entitle the holder thereof
         to 100 votes on all matters submitted to a vote of the stockholders of
         the Corporation. In the event the Corporation shall at any time declare
         or pay any dividend on the Common Stock payable in shares of Common
         Stock, or effect a subdivision or combination or consolidation of the
         outstanding shares of Common Stock (by reclassification or otherwise
         than by payment of a dividend in shares of Common Stock) into a greater
         or lesser number of shares of Common Stock, then in each such case the
         number of votes per share to which holders of shares of Series A
         Preferred Stock were entitled immediately prior to such event shall be
         adjusted by multiplying such number by a fraction, the numerator of
         which is the number of shares of Common Stock outstanding immediately
         after such event and the denominator of which is the number of shares
         of Common Stock that were outstanding immediately prior to such event.

                  Except as otherwise provided herein, in any other Certificate
         of Designations creating a series of Preferred Stock or any similar
         stock, or by law, the holders of shares of Series A Preferred Stock and
         the holders of shares of Common Stock and any other capital stock of
         the Corporation having general voting rights shall vote together as one
         class on all matters submitted to a vote of stockholders of the
         Corporation.

                  Except as set forth herein, or as otherwise provided by law,
         holders of Series A Preferred Stock shall have no special voting rights
         and their consent shall not be required (except to the extent they are
         entitled to vote with holders of Common Stock as set forth herein) for
         taking any corporate action.

                  Certain Restrictions.

                  Whenever quarterly dividends or other dividends or
         distributions payable on the Series A Preferred Stock as provided in
         Section 2 are in arrears, thereafter and until all accrued and unpaid
         dividends and distributions, whether or not declared, on shares of
         Series A Preferred Stock outstanding shall have been paid in full, the
         Corporation shall not:

                                      A-5
<PAGE>
                     declare or pay dividends, or make any other distributions,
                  on any shares of stock ranking junior (either as to dividends
                  or upon liquidation, dissolution or winding up) to the Series
                  A Preferred Stock;

                     declare or pay dividends, or make any other distributions,
                  on any shares of stock ranking on a parity (either as to
                  dividends or upon liquidation, dissolution or winding up) with
                  the Series A Preferred Stock, except dividends paid ratably on
                  the Series A Preferred Stock and all such parity stock on
                  which dividends are payable or in arrears in proportion to the
                  total amounts to which the holders of all such shares are then
                  entitled;

                     redeem or purchase or otherwise acquire for consideration
                  shares of any stock ranking junior (either as to dividends or
                  upon liquidation, dissolution or winding up) to the Series A
                  Preferred Stock, provided that the Corporation may at any time
                  redeem, purchase or otherwise acquire shares of any such
                  junior stock in exchange for shares of any stock of the
                  Corporation ranking junior (either as to dividends or upon
                  dissolution, liquidation or winding up) to the Series A
                  Preferred Stock; or

                     redeem or purchase or otherwise acquire for consideration
                  any shares of Series A Preferred Stock, or any shares of stock
                  ranking on a parity with the Series A Preferred Stock, except
                  in accordance with a purchase offer made in writing or by
                  publication (as determined by the Board of Directors) to all
                  holders of such shares upon such terms as the Board of
                  Directors, after consideration of the respective annual
                  dividend rates and other relative rights and preferences of
                  the respective series and classes, shall determine in good
                  faith will result in fair and equitable treatment among the
                  respective series or classes.

                  The Corporation shall not permit any subsidiary of the
         Corporation to purchase or otherwise acquire for consideration any
         shares of stock of the Corporation unless the Corporation could, under
         paragraph (A) of this Section 4, purchase or otherwise acquire such
         shares at such time and in such manner.

                  Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

                  Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made (1)
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received $100 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment,
provided that the 

                                      A-6
<PAGE>

holders of shares of Series A Preferred Stock shall be entitled to receive an
aggregate amount per share, subject to the provision for adjustment hereinafter
set forth, equal to 100 times the aggregate amount to be distributed per share
to holders of Common Stock, or (2) to the holders of shares of stock ranking on
a parity (either as to dividends or upon liquidation, dissolution or winding up)
with the Series A Preferred Stock, except distributions made ratably on the
Series A Preferred Stock and all such parity stock in proportion to the total
amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up. In the event the Corporation shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

                  Rank. The Series A Preferred Stock shall rank, with respect to
the payment of dividends and the distribution of assets, junior to all series of
any other class of the Corporation's Preferred Stock.

                  Amendment. The Certificate of Incorporation of the Corporation
shall not be amended in any manner which would materially alter or change the
powers, preferences or special rights of the Series A Preferred Stock so as to
affect them adversely without the 

                                      A-7
<PAGE>

affirmative vote of the holders of at least two-thirds of the outstanding shares
of Series A Preferred Stock, voting together as a single class.

                                                                      Exhibit C

                 SUMMARY OF RIGHTS TO PURCHASE PREFERRED SHARES

                  On September 15, 1998, the Board of Directors of Butler
Manufacturing Company (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, without
par value ("Common Shares"), of the Company. The dividend is payable on October
1, 1998 (the "Record Date") to the stockholders of record on that date. Each
Right entitles the registered holder to purchase from the Company one
one-hundredth of a share of Series A, Class 1 Preferred Stock, without par value
(the "Preferred Shares"), of the Company at a price of $160 per one
one-hundredth of a Preferred Share (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and UMB Bank, N.A., as
Rights Agent (the "Rights Agent").

                  Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 15% or more of the
outstanding Common Shares or (ii) 10 business days (or such later date as may be
determined by action of the Board of Directors prior to such time as any person
or group of affiliated persons becomes an Acquiring Person) following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the outstanding Common Shares
(the earlier of such dates being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of the Record Date, by such Common Share certificate with a copy
of this Summary of Rights attached thereto.

                  The Rights Agreement provides that, until the Distribution
Date (or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Common Shares. Until the Distribution Date
(or earlier redemption or expiration of the Rights), new Common Share
certificates issued after the Record Date upon transfer or new issuance of
Common Shares will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for Common Shares
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights being attached thereto, will also constitute the transfer of
the Rights associated with the Common Shares represented by such certificate. As
soon as practicable following the Distribution Date, separate certificates
evidencing the Rights ("Right Certificates") will be mailed to holders of record
of the Common Shares as of the close of business on the Distribution Date and
such separate Right Certificates alone will evidence the Rights.

                  The Rights are not exercisable until the Distribution Date.
The Rights will expire on September 30, 2008 (the "Final Expiration Date"),
unless the Final Expiration Date is extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case, as described below.

                                      C-1

                  The Purchase Price payable, and the number of Preferred Shares
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion price,
less than the then-current market price of the Preferred Shares or (iii) upon
the distribution to holders of the Preferred Shares of evidences of indebtedness
or assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

                  The number of outstanding Rights and the number of one
one-hundredths of a Preferred Share issuable upon exercise of each Right are
also subject to adjustment in the event of a stock split of the Common Shares or
a stock dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

                  Preferred Shares purchasable upon exercise of the Rights will
not be redeemable. Each Preferred Share will be entitled to a minimum
preferential quarterly dividend payment of $1 per share but will be entitled to
an aggregate dividend of 100 times the dividend declared per Common Share. In
the event of liquidation, the holders of the Preferred Shares will be entitled
to a minimum preferential liquidation payment of $100 per share but will be
entitled to an aggregate payment of 100 times the payment made per Common Share.
Each Preferred Share will have one vote, voting together with the Common Shares.
Finally, in the event of any merger, consolidation or other transaction in which
Common Shares are exchanged, each Preferred Share will be entitled to receive
100 times the amount received per Common Share. These rights are protected by
customary antidilution provisions.

                  In the event that the Company is acquired in a merger or other
business combination transaction or 50% or more of its consolidated assets or
earning power are sold after a person or group has become an Acquiring Person,
proper provision will be made so that each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereafter be void), will
thereafter have the right to receive, upon the exercise thereof at the then
current exercise price of the Right, that number of shares of common stock of
the acquiring company which at the time of such transaction will have a market
value of two times the exercise price of the Right. In the event that any person
or group of affiliated or associated persons becomes an Acquiring Person, proper
provision shall be made so that each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereafter be void), will
thereafter have the right to receive upon exercise that number of Common Shares
having a market value of two times the exercise price of the Right.

                  At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50% or more of
the outstanding Common Shares, the Board of Directors of the Company may
exchange the Rights (other than Rights owned by such 

                                      C-2
<PAGE>

person or group which will have become void), in whole or in part, at an
exchange ratio of one Common Share or one one-hundredth of a Preferred Share per
Right.

                  With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments require an adjustment of at least
1% in such Purchase Price. No fractional Preferred Shares will be issued (other
than fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

                  At any time prior to the acquisition by a person or group of
affiliated or associated persons of beneficial ownership of 15% or more of the
outstanding Common Shares, the Board of Directors of the Company may redeem the
Rights in whole, but not in part, at a price of $.01 per Right (the "Redemption
Price"). The redemption of the Rights may be made effective at such time on such
basis with such conditions as the Board of Directors in its sole discretion may
establish. Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

                  The terms of the Rights may be amended by the Board of
Directors of the Company without the consent of the holders of the Rights,
including an amendment to lower certain thresholds described above to not less
than the greater of (i) the sum of .001% and the largest percentage of the
outstanding Common Shares then known to the Company to be beneficially owned by
any person or group of affiliated or associated persons and (ii) 10%, except
that from and after such time as any person or group of affiliated or associated
persons becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights.

                  Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.

                  A copy of the Rights Agreement has been filed with the
Securities and Exchange Commission as an Exhibit to a Registration Statement on
Form 8-A dated       , 1998. A copy of the Rights Agreement is available free of
charge from the Company. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is hereby incorporated herein by reference.
