         Second Amended and Restated Rights Agreement (the "Amended Rights
Agreement" or "Agreement"), dated as of April 15, 1999, between Quanex
Corporation, a Delaware corporation (the "Company"), and American Stock Transfer
& Trust Co. (the "Rights Agent").

                              W I T N E S S E T H:

         WHEREAS, on August 28, 1986, the Board of Directors of the Company
authorized and declared a dividend distribution of one Right (as hereinafter
defined) for each outstanding share of Common Stock, $.50 par value per share,
of the Company (the"Common Stock") outstanding on September 12, 1986 (the
"Record Date"), which dividend distribution contemplated the issuance of one
Right (subject to adjustment as provided herein) for each share of Common Stock
of the Company issued between the Record Date and the earliest of the
Distribution Date and the Expiration Date (as such terms are hereinafter
defined), each Right representing the right to purchase one one-thousandth of a
share of Series A Junior Participating Preferred Stock of the Company having the
rights, powers and preferences set forth in the Certificate of Designation of
Series A Participating Preferred Stock filed as an exhibit to the Restated
Certificate of Incorporation of Quanex Corporation on November 17, 1995, as
amended by the Amendment (the "Certificate Amendment") attached hereto as
Exhibit A, upon the terms and subject to the conditions hereinafter set forth
(the "Right" or "Rights");

         WHEREAS, on February 25, 1999 (the "Amendment Date"), the Board of
Directors of the Company resolved to amend and restate this Agreement, and such
amendments shall become effective upon the filing of the Certificate Amendment
with the Secretary of State of Delaware;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto 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 that, together with all Affiliates (as such term is
hereinafter defined) and Associates (as such term is hereinafter defined) of
such Person, without the prior approval of the Company, shall be the Beneficial
Owner (as such term is hereinafter defined) of securities representing 20% or
more of the Voting Power (as such term is hereinafter defined) or who was such a
Beneficial Owner at any time after the date hereof, whether or not such Person
continues to be the Beneficial Owner of securities representing 20% or more of
the outstanding Voting Power, provided however, that Acquiring Person shall not
mean (i) the Company, (ii) any subsidiary of the Company (as such term is
hereinafter defined), (iii) any employee benefit plan of the Company or any of
its subsidiaries, or (iv) any entity holding securities of the Company
organized, appointed or established by the Company or any of its subsidiaries
for or pursuant to the terms of any such plan; and provided, further, that in no
event shall 


<PAGE>   5

a Person become an Acquiring Person solely as a result of a reduction in the
Company's outstanding securities, including repurchases of outstanding Company
securities by the Company, which reduction increases the percentage of Voting
Power beneficially owned by such Person (provided, however, that any subsequent
increase in the percentage of the Voting Power beneficially owned by such
Person, together with all Affiliates and Associates of such Person, without
prior approval of the Company shall cause such Person to be an Acquiring
Person).

         (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.

         understanding (whether or not in writing) or upon the exercise of
         conversion rights, exchange rights, rights (other than the Rights),
         warrants or options, or otherwise provided, however, that a Person
         shall not be deemed the "Beneficial Owner" of, or to "beneficially
         own," (i) securities tendered pursuant to a tender or exchange offer

         until such tendered securities are accepted for payment or exchange or

         with and between underwriters and selling group members with respect to
         a bona fide public offering of securities; or (B) the right to vote

         "Beneficial Owner" of, or to "beneficially own," any security under
         this clause (B) if the agreement, arrangement or understanding to vote
         such security (1) arises solely from a revocable proxy given in
         response to a public proxy or consent solicitation made pursuant to,
         and in accordance with, the applicable rules and regulations of the
         Exchange Act and (2) is not also then reportable by such person on

         any other Person (or any Affiliate or Associate thereof) with which
         such Person or any of such Person's Affiliates or Associates has any
         agreement, arrangement or understanding (whether or not in writing), or
         with which such Person or any of such Person's Affiliates have
         otherwise formed a group, for the purpose of acquiring, holding, voting
         (except pursuant to a revocable proxy as described in clause (B) of
         subparagraph (ii) of this paragraph (c)) or disposing of any securities

certificate.

         (c) Certificates issued for Common Stock (including, without
limitation, certificates issued upon transfer or exchange of Common Stock) after
the Amendment Date, but prior to the earlier of the Distribution Date or the

                  to certain Rights as set forth in the Second Amended and
                  Restated Rights Agreement between Quanex Corporation and

                  no longer be evidenced by this certificate. Quanex Corporation
                  will mail to the holder of this certificate a copy of the
                  Amended Rights Agreement without charge within five days after

                  circumstances, Rights issued to Acquiring Persons (as defined
                  in the Amended Rights Agreement) or certain related persons

                  11(a)(ii) and Section 13(a) of the Amended Rights Agreement.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Stock represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any of such certificates shall also constitute the
transfer of the Rights associated with the Common Stock represented by such
certificate.

         Section 4. Form of Rights Certificates.

         (a) The Rights Certificates (and the forms of election to purchase
shares and of assignment to be printed on the reverse thereof) shall each be
substantially in the form set forth in 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 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 11
and Section 23 hereof, the Rights Certificates, whenever distributed, shall be
dated as of the Amendment Date, and on their face shall entitle the holders
thereof to purchase such number of one one-thousandth of a share of Preferred
Stock as shall be set forth therein at the price per one one-thousandth of a
share set forth therein (the "Purchase Price"), but the number of such shares
and the Purchase Price shall be subject to adjustment as provided herein.

         (b) Any Rights Certificate issued pursuant to Section 3(a) hereof that
represents Rights beneficially owned by an Acquiring Person or any Associate or
Affiliate thereof and any Rights Certificate issued at any time upon the
transfer of any Rights to such an Acquiring Person or any Associate or Affiliate
thereof or to any nominee of such Acquiring Person, Associate or Affiliate, and
any Rights Certificate issued pursuant to Section 6 or Section 11 upon transfer,
exchange, replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain the following legend:

                  The Rights represented by this Rights Certificate were issued
                  to a Person who was an Acquiring Person or an Affiliate or an
                  Associate of an Acquiring Person. This Rights Certificate and
                  the Rights represented hereby may become void to the extent
                  provided by, and under certain circumstances as specified in,
                  Section 7(e) of the Amended Rights Agreement.

The provisions of Section 7(e) of this Amended Rights Agreement shall be
operative whether or not the foregoing legend is contained on any such Rights
Certificate.

         Section 5. Countersignature and Registration. The Rights Certificates
shall be executed on behalf of the Company by its Chairman of the Board, any
Vice Chairman of the Board, any President or any Vice President, either manually
or by facsimile signature, and shall have affixed thereto the Company's seal or
a facsimile thereof which shall be attested by the Secretary or an Assistant
Secretary of the Company, either manually or by facsimile signature. The Rights
Certificates shall be countersigned by the Rights Agent either manually or by
facsimile signature and shall not be valid for any purpose unless so
countersigned. In case any officer of the Company who shall have signed any of
the Rights Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Rights 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 Rights Certificates had not ceased to be such
officer of the Company; and any Rights Certificates may be signed on behalf of
the Company by any person who, at the actual date of the execution of such
Rights Certificate, shall be a proper officer of the Company to sign such Rights
Certificate, although at the date of the execution of this Amended 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 one of its offices in Houston, Texas, or New York, New York, books
for registration and transfer of the Rights Certificates issued hereunder. Such
books shall show the names and addresses of the respective holders of the Rights
Certificates, the number of Rights evidenced on its face by each of the Rights
Certificates and the date of each of the Rights Certificates.

         Section 6. Transfer, Split Up, Combination and Exchange of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. Subject
to the provisions of Section 15 hereof, at any time after the close of business
on the Distribution Date, and at or prior to the close of business on the
Expiration Date, any Rights Certificate or Certificates may be transferred,
split up, combined or exchanged for another Rights Certificate or Rights
Certificates, entitling the registered holder to purchase a like number of
shares of Preferred Stock as the Rights Certificate or Rights Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate shall
make such request in writing delivered to the Rights Agent, and shall surrender
the Rights Certificate or Rights 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
Rights Certificate or Rights 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 Rights Certificates.

         Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Rights
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and upon surrender to the Rights Agent
and cancellation of the Rights Certificate if mutilated, the Company shall
execute and deliver a new Rights Certificate of like tenor to the Rights Agent
for countersignature and delivery to the registered owner in lieu of the Rights
Certificate so lost, stolen, destroyed or mutilated.

         Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights.

         (a) The registered holder of any Rights 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 presentation of the Rights
Certificate, with the appropriate form of election to purchase on the reverse
side 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-thousandth of a share of Preferred Stock (or such other number of shares or
other securities) as to which the Rights are exercised, at or prior to the
earliest of (i) the close of business on April 15, 2009 (the "Final Expiration
Date"), or (ii) the time at which the Rights are redeemed as provided in Section
24 hereof or (iii) the consummation of a transaction contemplated by Section
13(d) hereof (such earliest time being herein referred to as the "Expiration
Date"). Notwithstanding any other provision of this Agreement, any Person who
prior to the Distribution Date becomes a recordholder of shares of Common Stock
may exercise all of the rights of a registered holder of a Rights Certificate
with respect to the Rights associated with such shares of Common Stock in
accordance with and subject to the provisions of this Agreement, including the
provisions of Section 7(e) hereof, as of the date such Person becomes a
recordholder of shares of Common Stock.

         (b) The Purchase Price for each one one-thousandth share of Preferred
Stock pursuant to the exercise of a Right shall initially be $90.00, shall be
subject to adjustment from time to time as provided in Sections 11 and 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 Rights Certificate representing exercisable
Rights, with the appropriate form of election to purchase duly executed shares,
accompanied by payment of the Purchase Price for the shares (or other securities
or property) to be purchased and an amount equal to any applicable transfer tax
(as determined by the Rights Agent) in cash, or by certified check or bank draft
payable to the order of the Company, the Rights Agent shall, subject to Section
21(k), thereupon promptly (i)(A) requisition from any transfer agent of the
shares of Preferred Stock (or make available, if the Rights Agent is the
transfer agent) certificates for the number of shares of Preferred Stock to be
purchased, and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company, in its sole discretion,
shall have elected to deposit the shares of Preferred Stock issuable upon
exercise of the Rights hereunder into a depositary, requisition from the
depositary agent depositary receipts representing such number of one
one-thousandths of a share of Preferred Stock as are to be purchased (in which
case certificates for the shares of Preferred Stock represented by such receipts
shall be deposited by the transfer agent with the depositary agent) and the
Company shall direct the depositary agent to comply with such request, (ii) when
appropriate, requisition from the Company the amount of cash, if any, to be paid
in lieu of issuance of fractional shares in accordance with Section 15, (iii)
promptly 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
Rights Certificate, registered in such name or names as may be designated by
such holder and (iv) when appropriate, after receipt promptly deliver such cash
to or upon the order of the registered holder of such Rights Certificate. In the
event that the Company is obligated to issue other securities of the Company
and/or distribute other property pursuant to Section 11(a), the Company shall
make all arrangements necessary so that such other securities and/or property
are available for distribution by the Rights Agent, if and when appropriate. In
addition, in the case of an exercise of the Rights by a holder pursuant to
Section 11(a)(ii), the Rights Agent shall return such Rights Certificate to the
registered holder thereof after imprinting, stamping or otherwise indicating


                                      -7-
<PAGE>   11

thereon that the rights represented by such Rights Certificate no longer include
the rights provided by Section 11(a)(ii) of the Amended Rights Agreement and if
less than all the Rights represented by such Rights Certificate were so
exercised, the Rights Agent shall indicate on the Rights Certificate the number
of Rights represented thereby that continue to include the rights provided by
Section 11(a)(ii).

         (d) In case the registered holder of any Rights Certificate shall
exercise (except pursuant to Section 11(a)(ii)) less than all the Rights
evidenced thereby, a new Rights Certificate evidencing Rights equivalent to the
Rights remaining unexercised shall be issued by the Rights Agent and delivered
to the registered holder of such Rights Certificate or to his duly authorized
assigns, subject to the provisions of Section 15 hereof.

         (e) Notwithstanding anything in this Agreement to the contrary, if
there occurs the transaction set forth in Section 11(a)(ii) or Section 13(a),
then any Rights that are or were on or after the earlier of the Distribution
Date or the Stock Acquisition Date beneficially owned by an Acquiring Person or
any Associate or Affiliate shall become void with respect to the rights provided
under Section 11(a)(ii) and Section 13(a), and any holder of such Rights shall
thereafter have no right to exercise such Rights under the provisions of Section
11(a)(ii) and Section 13(a).

         (f) Notwithstanding anything in this Agreement to the contrary, neither
the Rights Agent nor the Company shall be obligated to undertake any action with
respect to a registered holder upon the occurrence of any purported exercise as
set forth in this Section 7 unless the certificate contained in the appropriate
form of election to purchase set forth on the reverse side of the Rights
Certificate surrendered for such exercise shall have been properly completed and
duly executed by the registered holder thereof and the Company shall have been
provided with such additional evidence of the identity of the Beneficial Owner
(or former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request.

         Section 8. Cancellation and Destruction of Rights Certificates. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or 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 Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Amended 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 Rights Certificate purchased or
acquired by the Company otherwise than upon the exercise thereof. The Rights
Agent shall deliver all canceled Rights Certificates to the Company, or shall,
at the written request of the Company, destroy such canceled Rights
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

         Section 9. Reservation and Availability of Preferred Stock.

         (a) The Company covenants and agrees that it shall cause to be reserved
and kept available out of its authorized and unissued shares of Preferred Stock,
or any authorized and issued shares of Preferred Stock held in its treasury, the
number of shares of Preferred Stock (and/or other 


                                      -8-
<PAGE>   12

securities) that will be sufficient to permit the exercise, to the extent
provided in Section 11(a)(i), and in accordance with the terms of Section 7, of
all outstanding Rights.

         (b) So long as the shares of Preferred Stock (or other securities)
issuable upon the exercise of the Rights may be listed on any national
securities exchange, the Company shall use its best efforts to cause, from and
after such time as the Rights become exercisable, all shares (or other
securities) reserved for such issuance to be listed on such exchange upon
official notice of issuance upon such exercise.

         (c) The Company covenants and agrees that it shall take all such action
as may be necessary to ensure that all shares of Preferred Stock and/or other
securities delivered upon exercise of Rights shall, at the time of delivery of
the certificates for such shares or other securities (subject to payment of the
Purchase Price), be duly and validly authorized and issued and fully paid and
nonassessable shares or securities.

         (d) The Company further covenants and agrees that it shall pay when due
and payable any and all federal and state transfer taxes and charges that may be
payable in respect of the issuance or delivery of the Rights Certificates or of
any certificates for shares of Preferred Stock and/or other securities upon the
exercise of Rights. The Company shall not, however, be required to pay any
transfer tax that may be payable in respect of any transfer or delivery of
Rights Certificates to a person other than, or in respect of the issuance or
delivery of the shares of Preferred Stock and/or other securities in a name
other than that of, the registered holder of the Rights Certificates evidencing
Rights surrendered for exercise or to issue or deliver any certificates for
shares of Preferred Stock, and/or other securities in a name other than that of
the registered holder upon the exercise of any Rights until such tax shall have
been paid (any such tax being payable by the holder of such Rights Certificate
at the time of surrender) or until it has been established to the Company's
satisfaction that no such tax is due.

         (e) The Company shall use its best efforts to (i) file, as soon as
practicable following the Distribution Date, a registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), with respect to the
securities purchasable upon exercise of the Rights on an appropriate form, (ii)
cause such registration statement to become effective as soon as practicable
after such filing, and (iii) cause such registration statement to remain
effective (with a prospectus at all times meeting the requirements of the
Securities Act and the rules and regulations thereunder) until the date of the
expiration of the rights provided by Section 11(a)(ii). The Company will also
take such action as may be appropriate under the blue sky laws of the various
states.

         Section 10. Preferred Stock Record Date. Each person in whose name any
certificate for shares of Preferred Stock (or other securities) is issued upon
the exercise of Rights shall for all purposes be deemed to have become the
holder of record of the shares of Preferred Stock (or other securities)
represented thereby on, and such certificate shall be dated, the date upon which
the Rights Certificate evidencing such Rights was duly presented and payment of
the Purchase Price (and any applicable transfer taxes) was made; provided,
however, that if the date of such presentation and payment is a date upon which
the Preferred Stock (or other securities) transfer books of the Company are
closed, such person shall be deemed to have become the recordholder of such
shares on, and such certificate shall be dated, the next succeeding Business Day
on which the Preferred Stock (or other 


                                      -9-
<PAGE>   13

securities) transfer books of the Company are open. Prior to the exercise of
the Rights evidenced thereby, the holder of a Rights Certificate, as such,
shall not be entitled to any rights of a shareholder of the Company with
respect to 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 and Kind of Shares or
Number of Rights. The Purchase Price, the number of 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 August
         28, 1986 (A) declare a dividend on the Preferred Stock payable in
         shares of Preferred Stock, (B) subdivide the outstanding Preferred
         Stock, (C) combine the outstanding Preferred Stock into a smaller
         number of shares or (D) issue any shares of its capital stock in a
         reclassification of the Preferred Stock (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) and in Section 7(e), 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 and
         other securities that, if such Right had been exercised immediately
         prior to such date and at a time when the Preferred Stock transfer
         books of the Company were open, he would have owned upon such exercise
         and been entitled to receive by virtue of such dividend, subdivision,
         combination or reclassification. If an event occurs that would require
         an adjustment under both Section 11(a)(i) and Section 11(a)(ii), the
         adjustment provided for in this Section 11(a)(i) shall be in addition
         to, and shall be made prior to, any adjustment required pursuant to
         Section 11(a)(ii).

                  (ii) In the event that any Person (other than the Company, any
         subsidiary of the Company, any employee benefit plan of the Company or
         any of its subsidiaries, or any entity holding securities of the
         Company organized, appointed or established by the Company or any of
         its subsidiaries for or pursuant to the terms of any such plan), alone
         or together with its Affiliates and Associates, shall become an
         Acquiring Person (except pursuant to a tender or exchange offer for all
         outstanding shares of Common Stock at a price and on terms determined
         by at least a majority of the members of the Board of Directors who are
         not officers of the Company, an Acquiring Person or Affiliates or
         Associates thereof, to be both adequate and otherwise in the best
         interests of the Company and its shareholders (other than the Person or
         an Affiliate or Associate thereof on whose behalf the offer is being
         made) (a "Permitted Offer")), then proper provision shall be made so
         that each holder of a Right, except as provided in Section 7(e) hereof,
         shall, for a period of 60 days after the later of the occurrence of any
         such event or the effective date of an appropriate registration
         statement pursuant to Section 9, have a right to receive, upon exercise
         thereof at the then-current Purchase Price in accordance with the terms
         of this Agreement, in lieu of shares of Preferred Stock, such number of
         shares of Common Stock of the Company as shall equal the result



                                     -10-
<PAGE>   14

         obtained by (x) multiplying the then-current Purchase Price by the
         then-number of one one)thousandths of a share of Preferred Stock for
         which a Right is then exercisable and (y) dividing that product by 50%
         of the current market price per one share of Common Stock (determined
         pursuant to Section 11(d)) on the date of the occurrence of the event
         set forth in this subparagraph (ii) (such number of shares being
         referred to as the "number of Adjustment Shares")); provided, however,
         that if the transaction that would otherwise give rise to the foregoing
         adjustment is also subject to the provisions of Section 13 hereof, then
         only the provisions of Section 13 hereof shall apply and no adjustment
         shall be made pursuant to this Section 11(a)(ii).

                   (iii) In the event that there shall not be sufficient
         treasury shares or authorized but unissued shares of Common Stock to
         permit the exercise in full of the Rights in accordance with the
         foregoing subparagraph (ii) and the Rights become so exercisable, the
         Company shall take all such action as may be necessary to authorize
         additional shares of Common Stock for issuance upon exercise of the
         Rights, including the calling of a meeting of shareholders; provided,
         however, that if the Company is unable to cause the authorization of a
         sufficient number of additional shares of Common Stock within 60 days
         of the date that the Rights become so exercisable, then proper
         provision shall be made so that each holder of a Right, except as
         provided in Section 7(e) hereof, after 60 days from the date the Rights
         become so exercisable, shall have a right to receive, upon exercise
         thereof at the then- current Purchase Price in accordance with the
         terms of this Agreement, such number of one one-thousandth of a share
         of Preferred Stock of the Company as shall equal the result obtained by
         (x) multiplying the then-current Purchase Price by the then-number of
         one one)thousandths of a share of Preferred Stock for which a Right is
         then exercisable and (y) dividing that product by 50% of the current
         market price per one share of Common Stock (determined pursuant to
         Section 11(d)) on the date of the occurrence of the event set forth in
         this subparagraph (ii). To the extent that the Company determines that
         some action need be taken pursuant to this Section 11(a)(iii), the
         Board of Directors may temporarily suspend the exercisability of the
         Rights for a period of up to 60 days following the date on which the
         event described in Section 11(a)(ii) shall have occurred, in order to
         seek any authorization of additional shares of Common Stock and/or to
         decide the appropriate form of distribution to be made pursuant to the
         above proviso and to determine the value thereof. In the event of any
         such suspension, the Company shall issue a public announcement stating
         that the exercisability of the Rights has been temporarily suspended.

         (b) If the Company shall fix a record date for the issuance of rights,
options or warrants to all holders of Preferred Stock entitling them (for a
period expiring within 45 calendar days after such record date) to subscribe for
or purchase Preferred Stock (or shares having the same or more favorable rights,
privileges and preferences as the Preferred Stock ("equivalent preferred
stock")) or securities convertible into Preferred Stock or equivalent preferred
stock at a price per share of Preferred Stock or per share of equivalent
preferred stock (or having a conversion price per share, if a security
convertible into Preferred Stock or equivalent preferred stock) less than the
current market price" (as defined in Section 11(d)) per share of 


                                     -11-
<PAGE>   15

Preferred Stock 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 before such record date by a fraction, the numerator of
which shall be the number of shares of Preferred Stock outstanding on such
record date, plus the number of shares of Preferred Stock that the aggregate
offering price of the total number of shares of Preferred Stock and/or
equivalent preferred stock 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 shares of Preferred Stock outstanding on such record date, plus the number
of additional shares of Preferred Stock and/or equivalent preferred stock to be
offered for subscription or purchase (or into which the convertible securities
so to be offered are initially convertible). 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 determined reasonably and
with good faith to the holders of Rights by the Board of Directors of the
Company, whose determination shall be described in a statement filed with the
Rights Agent and shall be binding on the Rights Agent. Shares of Preferred
Stock 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 or warrants are not so issued, the Purchase Price shall be adjusted
to be the Purchase Price that would then be in effect if such record date had
not been fixed.

         (c) If the Company shall fix a record date for the making of a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of evidences of indebtedness, cash (other than a regular
quarterly cash dividend out of the earnings or retained earnings of the
Company), assets (other than a dividend payable in Preferred Stock, but
including any dividend payable in stock other than Preferred Stock) or
subscription rights or warrants (excluding those referred to in Section 11(b)),
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 current market price (as
defined in Section 11(d)) per share of Preferred Stock on such record date, less
the fair market value (as determined reasonably and with good faith to the
holders of Rights by the Board of Directors of the Company, whose determination
shall be described in a statement filed with the Rights Agent and shall be
binding on the Rights Agent) of the portion of the cash, assets or evidences of
indebtedness so to be distributed or of such subscription rights or warrants
distributable in respect of one share of Preferred Stock and the denominator of
which shall be the current market price per share of the Preferred Stock. 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 that would be in effect if such
record date had not been fixed.

                  (d)(i) For the purpose of any computation hereunder, the
         "current market price" per share of Common Stock on any date shall be
         deemed to be the average of the daily closing prices per share of such
         Common Stock 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 Common
         Stock is determined during a period following the announcement by the
         issuer of such Common Stock of (A) a dividend or distribution on such
         Common Stock payable in shares of such Common Stock or securities
         convertible into shares of such Common Stock or (B) any subdivision,
         combination or reclassification of such Common Stock, 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 market price" shall 


                                     -12-
<PAGE>   16

         be properly adjusted to take into account ex-dividend trading. 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 shares of Common Stock 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 listed on the principal national securities exchange on
         which the shares of Common Stock are listed or admitted to trading or,
         if the shares of Common Stock 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 the National Association of
         Securities Dealers, Inc. Automated Quotation System ("NASDAQ") or such
         other system then in use, or, if on any such date the shares of Common
         Stock 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 Common Stock selected by the Board of
         Directors of the Company. If on any such date no market maker is
         making a market in the Common Stock, the fair value of such shares on
         such date as determined reasonably and with good faith by the Board of
         Directors of the Company shall be used and shall be binding on the
         Rights Agent. The term "Trading Day" shall mean a day on which the
         principal national securities exchange on which the shares of Common
         Stock are listed or admitted to trading is open for the transaction of
         business or, if the shares of Common Stock are not listed or admitted
         to trading on any national securities exchange, a Business Day. If the
         Common Stock is not publicly held or not so listed or traded, "current
         market price" per share shall mean the fair value per share determined
         reasonably and with good faith to the holders of Rights by the Board
         of Directors of the Company, whose determination shall be described in
         a statement filed with the Rights Agent and shall be binding on the
         Rights Agent.

                  (ii) For the purpose of any computation hereunder, the
         "current market price" per share (or one one-thousandth of a share) of
         Preferred Stock shall be determined in the same manner as set forth
         above for the Common Stock in clause (i) of this Section 11(d) (other
         than the last sentence thereof). If the current market price per share
         (or one one-thousandth of a share) of Preferred Stock cannot be
         determined in the manner provided above or if the Preferred Stock is
         not publicly held or listed or traded in a manner described in clause
         (i) of this Section 11(d), the "current market price" per share of
         Preferred Stock shall be conclusively deemed to be an amount equal to
         1000 (as such number may be appropriately adjusted for such events as
         stock splits, stock dividends and recapitalizations with respect to the
         Common Stock occurring after the date of this Agreement) multiplied by
         the current market price per share of the Common Stock and the "current
         market price" per one one)thousandth of a share of Preferred Stock
         shall be equal to the current market price per share of the Common
         Stock (as appropriately adjusted). If neither the Common Stock nor the
         Preferred Stock is publicly held or so listed or traded, "current
         market price" per share 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 and shall be conclusive for all purposes.

         (e) Anything herein to the contrary notwithstanding, 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 that 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 ten)thousandth of a share of Common Stock or one
ten-millionth of a share of Preferred Stock or other share, 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 that mandates such adjustment or (ii) the
Expiration Date.

         (f) If as a result of any provision of Section 11(a), the holder of any
Right thereafter exercised shall become entitled to receive any shares of
capital stock of the Company other than Preferred Stock, thereafter the number
of such other shares so 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 shares contained in Section
11(a) through (c), inclusive, and the provisions of Sections 7, 9, 10, 13 and 15
hereof with respect to the Preferred Stock 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 shares of Preferred
Stock 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 Section 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)thousandths of
a share of Preferred Stock (calculated to the nearest one-millionth) obtained by
(i) multiplying (x) the number of one one)thousandths of a share of Preferred
Stock 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 shares of Preferred Stock purchasable upon the
exercise of a Right. Each of the Rights outstanding after the adjustment in the
number of Rights shall be exercisable for the number of one one-thousandths of a
share of Preferred Stock 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
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 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 Rights Certificates have
been issued, shall be at least 10 days later than the date of the public
announcement. If Rights Certificates have been 


                                     -14-
<PAGE>   18

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 Rights Certificates on such record date Rights
Certificates evidencing, subject to Section 15 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 Rights Certificates held by such
holders prior to the date of adjustment, and upon surrender thereof, if
required by the Company, new Rights Certificates evidencing all the Rights to
which such holders shall be entitled after such adjustment. Rights Certificates
so to be distributed shall be issued, executed and countersigned in the manner
provided for herein (and may bear, at the option of the Company, the adjusted
Purchase Price) and shall be registered in the names of the holders of record
of Rights 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 shares of Preferred Stock issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue
to express the Purchase Price per share and the number of shares that were
expressed in the initial Rights Certificates issued hereunder.

         (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below the then par value, if any, of the shares of Preferred
Stock, Common Stock or other securities issuable upon exercise of the Rights,
the Company shall take any corporate action that may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue
fully paid and nonassessable shares of Preferred Stock, Common Stock or other
securities at such adjusted Purchase Price. If upon any exercise of the Rights,
a holder is to receive a combination of Common Stock, Preferred Stock, and other
property, a portion of the consideration paid upon such exercise, equal to at
least the then par value of a share of Common Stock of the Company, shall be
allocated as the payment for each share of Common Stock of the Company so
received.

         (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 after such record date
the shares of Preferred Stock and other capital stock or securities of the
Company, if any, issuable upon such exercise over and above the shares of
Preferred Stock 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 to the contrary in this Section 11 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 Stock, issuance
wholly for cash of any shares of Preferred Stock at less than the current market
price, issuance wholly for cash of shares of Preferred Stock or securities that
by their terms are convertible into or exchangeable for shares of Preferred
Stock, stock dividends or issuance of rights, options or warrants referred to
hereinabove in this Section 11, hereafter made by the Company to holders of its
Preferred Stock shall not be taxable to such shareholders.


                                     -15-
<PAGE>   19

         (n) Anything in this Agreement to the contrary notwithstanding, in the
event that the Company shall at any time after August 28, 1986 and prior to the
Distribution Date (i) declare a dividend on the outstanding shares of Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, (iii) combine the outstanding Common Stock into a smaller number of
shares, or (iv) issue any shares of its capital stock in a reclassification of
the outstanding Common Stock, the number of Rights associated with each share of
Common Stock then outstanding, or issued or delivered thereafter but prior to
the Distribution Date, shall be proportionately adjusted so that the number of
Rights thereafter associated with each share of Common Stock following any such
event shall equal the result obtained by multiplying the number of Rights
associated with each share of Common Stock immediately prior to such event by a
fraction the numerator of which shall be the total number of shares of Common
Stock outstanding immediately prior to the occurrence of the event and the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately following the occurrence of such event.

         (o) The exercise of Rights under Section 11(a)(ii) shall only result in
the loss of rights under Section 11(a)(ii) to the extent so exercised and shall
not otherwise affect the rights represented by the Rights under this Amended
Rights Agreement, including the rights represented by Section 13.

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 and 13 hereof, the
Company shall (a) promptly prepare a certificate setting forth such adjustment
and a brief statement of the facts accounting for such adjustment, (b) promptly
file with the Rights Agent and with each transfer agent for the Preferred Stock
and the Common Stock a copy of such certificate and (c) mail a brief summary
thereof to each holder of a Rights Certificate in accordance with Section 26
hereof. The Rights Agent shall be fully protected in relying on any such
certificate and on any adjustment therein contained and shall not be deemed to
have knowledge of any such adjustment unless and until it shall have received
such certificate.

         Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earning Power.

         (a) In the event that, following the Stock Acquisition Date, directly
or indirectly, (x) the Company shall consolidate with, or merge with and into,
any other Person, (y) 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 (other than, in the case of either transaction
described in (x) or (y), a merger or consolidation that would result in all of
the Voting Power represented by the securities of the Company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into securities of the surviving entity) all
of the Voting Power represented by the securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation and
the holders of such securities not having changed as a result of such merger or
consolidation), or (z) the Company sells, mortgages or otherwise transfers (or
one or more of its subsidiaries shall sell, mortgage or otherwise transfer), in
one or more transactions, assets or earning power aggregating more than 50% of
the assets or earning power of the Company and its subsidiaries (taken as a
whole) to any other Person, then, and in each such case, proper provision shall
be made so that (i) following the Distribution Date, each holder of a Right,
subject to Section 7(e), shall have the right to receive, upon the exercise
thereof at the then-current Purchase Price in accordance with the terms of this
Agreement, such number of shares of 


                                     -16-
<PAGE>   20

freely tradeable Common Stock of the Principal Party (as hereinafter defined),
free and clear of liens, rights of call or first refusal, encumbrances or other
adverse claims, as shall be equal to the result obtained by (x) multiplying the
then-current Purchase Price by the number of one one)thousandths of a share of
Preferred Stock for which a Right is then exercisable (without taking into
account any adjustment previously made pursuant to Section 11(a)(ii) hereof)
and (y) dividing that product by 50% of the current market price per share of
the Common Stock of such Principal Party (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; (ii) such Principal Party 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 Principal Party, it
being specifically intended that the provisions of Section 11 hereof shall
apply to such Principal Party; and (iv) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
shares of its Common Stock 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
its shares of Common Stock thereafter deliverable upon the exercise of the
Rights.

         (b)      "Principal Party" shall mean

                  (i) in the case of any transaction described in (x) or (y) of
         the first sentence of this Section 13, the Person that is the issuer of
         any securities into which shares of Common Stock of the Company are
         converted in such merger or consolidation, and if no securities are so
         issued, the Person that is the other party to the merger or
         consolidation (including, if applicable, the Company, if it is the
         surviving corporation); and

                  (ii) in the case of any transaction described in (z) of the
         first sentence in this Section 13, the Person that is the party
         receiving the greatest portion of the assets or earning power
         transferred pursuant to such transaction or transactions;

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding 12-month
period registered under Section 12 of the Exchange Act, and such Person is a
direct or indirect subsidiary or Affiliate of another Person, "Principal Party"
shall refer to such other Person; (2) in case such Person is a subsidiary,
directly or indirectly, or Affiliate of more than one Person, the Common Stocks
of two or more of which are and have been so registered, "Principal Party" shall
refer to whichever of such Persons is the issuer of the Common Stock having the
greatest aggregate market value; and (3) in case such Person is owned, directly
or indirectly, by a joint venture formed by two or more Persons that are not
owned, directly or indirectly, by the same Person, the rules set forth in (1)
and (2) above shall apply to each of the chains of ownership having an interest
in such joint venture as if such party were a "Subsidiary" of both or all of
such joint venturers and the Principal Parties in each such chain shall bear the
obligations set forth in this Section 13 in the same ratio as their direct or
indirect interests in such Person bear to the total of such interests.


                                     -17-
<PAGE>   21

         (c) The Company shall not consummate any such consolidation, merger,
sale or transfer unless the Principal Party shall have a sufficient number of
authorized shares of its Common Stock that have not been issued or reserved for
issuance to permit the exercise in full of the Rights in accordance with this
Section 13 and unless prior thereto the Company and each Principal Party and
each other Person who may become a Principal Party as a result of such
consolidation, merger, sale or transfer shall have executed and delivered to the
Rights Agent a supplemental agreement providing for the terms set forth in
paragraphs (a) and (b) of this Section 13 and further providing that, as soon as
practicable after the date of any consolidation, merger, sale or transfer of
assets mentioned in paragraph (a) of this Section 13, the Principal Party at its
own expense shall:

                  (i) prepare and file a registration statement under the
         Securities Act with respect to the rights and the securities
         purchasable upon exercise of the Rights on an appropriate form, will
         use its best efforts to cause such registration statement to become
         effective as soon as practicable after such filing and will use its
         best efforts to cause such registration statement to remain effective
         (with a prospectus at all times meeting the requirements of the
         Securities Act) until the Expiration Date;

                  (ii) use its best efforts to qualify or register the Rights
         and the securities purchasable upon exercise of the rights under the
         blue sky laws of such jurisdictions as may be necessary or appropriate;
         and

                  (iii) deliver to holders of the Rights historical financial
         statements for the Principal Party and each of its Affiliates that
         comply in all material respects with the requirements for registration
         on Form 10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. The rights under this Section 13
shall be in addition to the rights to exercise Rights and adjustments under
Section 11(a)(ii) and shall survive any exercise thereunder.

         (d) Notwithstanding anything in this Agreement to the contrary, Section
13 shall not be applicable to a transaction described in subparagraphs (x) and
(y) of Section 13(a) if (i) such transaction is consummated with a Person or
Persons who acquired shares of Common Stock pursuant to a Permitted Offer (or a
wholly owned subsidiary of any such Person or Persons), (ii) the price per share
of Common Stock offered in such transaction is not less than the price per share
of Common Stock paid to all holders of Common Stock whose shares were purchased
pursuant to such Permitted Offer and (iii) the form of consideration being
offered to the remaining holders of Common Stock pursuant to such transaction is
the same as the form of consideration paid pursuant to such Permitted Offer.
Upon consummation of any such transaction contemplated by this subsection (d),
all Rights hereunder shall expire.

         Section 14. Additional Covenants.

         (a) After the Stock Acquisition Date, the Company covenants and agrees
that it shall not (i) consolidate with, (ii) merge with or into, or (iii) sell
or transfer to, in one or more transactions, assets or earning power aggregating
more than 50% of the assets or earning power of the Company and its subsidiaries
taken as a whole, any other Person if at the time of or after such
consolidation, 

                                     -18-
<PAGE>   22

merger or sale there are any charter or by-law provisions or any rights,
warrants or other instruments outstanding or any other action taken that would
diminish or otherwise eliminate the benefits intended to be afforded by the
Rights. The Company shall not consummate any such consolidation, merger or sale
unless prior thereto the Company and such other Person shall have executed and
delivered to the Rights Agent a supplemental agreement evidencing compliance
with this subsection.

         (b) The Company covenants and agrees that, after the Stock Acquisition
Date, it will not, except as permitted by Section 24 hereof, take any action the
purpose or effect of which is to diminish or otherwise eliminate the benefits
intended to be afforded by the Rights.

         Section 15. Fractional Rights and Fractional Shares.

         (a) The Company shall not be required to issue fractions of Rights,
except prior to the Distribution Date as provided in Section 11(n), or to
distribute Rights Certificates that evidence fractional Rights. In lieu of such
fractional Rights, there shall be paid to the registered holders of the Rights
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 15(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 of the Rights for any day shall
be the last sale price, 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 reasonably and with good faith to the
holders of Rights by the Board of Directors of the Company shall be used and
shall be binding on the Rights Agent.

         (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions that are integral multiples of one
one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates that evidence fractional shares of Preferred Stock
(other than fractions that are integral multiples of one one-thousandth of a
share of Preferred Stock). Fractions of shares of Preferred Stock in integral
multiples of one one-thousandth of a share of Preferred Stock 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 shares of Preferred Stock represented
by such depositary receipts. In lieu of fractional shares of Preferred Stock
that are not integral multiples of one one-thousandth of a share of Preferred
Stock, the Company may pay to the registered holders of Rights 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 one-thousandth of a
share of Preferred Stock. For purposes of this Section 15(b), the current
market value of one one-thousandth of a share of Preferred Stock shall be one
one-thousandth of the closing price of a share of Preferred Stock (as
determined pursuant to Section 11(d)(ii) hereof) for the Trading Day
immediately prior to the date of such exercise.


                                     -19-
<PAGE>   23

         (c) Following the occurrence of one of the transactions or events
specified in Section 11 giving rise to the right to receive securities other
than Common Stock or Preferred Stock upon the exercise of a Right, the Company
shall not be required to issue fractions of shares or units of such other
securities upon exercise of the Rights or to distribute certificates that
evidence fractional shares of such other securities. In lieu of fractional
shares or units of such other securities, the Company may pay to the registered
holders of Rights 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 a share or unit of such other securities. For purposes of this Section
15(c), the current market value shall be determined in the manner set forth in
Section 11(d) hereof for the Trading Day immediately prior to the date of such
exercise and, if such other security is not traded, each such other security
shall have the value of one one-thousandth of a share of Preferred Stock.

         (d) Except as otherwise expressly provided herein, the holder of a
Right by the acceptance of the Rights expressly waives his right to receive any
fractional Rights or any fractional shares upon exercise of a Right.

         Section 16. Rights of Action. All rights of action in respect of this
Agreement are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of
the Common Stock); and any registered holder of any Rights Certificate (or,
prior to the Distribution Date, of the Common Stock), without the consent of
the Rights Agent or of the holder of any other Rights Certificate (or, prior to
the Distribution Date, of the Common Stock), may, in his own behalf and for his
own benefit, enforce, and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise act in respect of, his
right to exercise the Rights evidenced by such Rights Certificate in the manner
provided in such Rights 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 shall be entitled to
specific performance of the obligations hereunder and injunctive relief against
actual or threatened violations of the obligations hereunder of any Person
subject to this Agreement. Holders of Rights shall be entitled to recover the
reasonable costs and expenses, including attorneys' fees, incurred by them in
any action to enforce the provisions of this Agreement.

         Section 17. Agreement of Rights Holders. Every holder of a Right by
accepting the same consents and agrees with the Company 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 Common Stock;

         (b) after the Distribution Date, the Rights 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 a Rights Certificate (or, prior to the Distribution Date, the
associated Common Stock certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Rights Certificates or the associated Common Stock


                                     -20-
<PAGE>   24

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.

         Section 18. Rights Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the shares of Preferred
Stock, Common Stock or any other securities of the Company that may at any time
be issuable on the exercise of the Rights represented thereby, nor shall
anything contained herein or in any Rights Certificate be construed to confer
upon the holder of any Rights Certificate, as such, any of the rights of a
shareholder of the Company or any right to vote for the election of directors
or upon any matter submitted to shareholders at any meeting thereof, or to give
or withhold consent to any corporate action, or to receive notice of meetings
or other actions affecting shareholders (except as provided in Section 25
hereof), or to receive dividends or subscription rights, or otherwise, until
the Right or Rights evidenced by such Rights Certificate shall have been
exercised in accordance with the provisions thereof.

         Section 19. Concerning the Rights Agent. The Company agrees to pay to
the Rights Agent reasonable compensation for all services rendered by it
hereunder as agreed, and, from time to time, on demand of the Rights Agent, its
reasonable expenses and counsel fees and disbursements and other disbursements
incurred in the administration and execution of this Agreement and the exercise
and performance of its duties hereunder. The Company also agrees to indemnify
the Rights Agent 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 arising
therefrom, directly or indirectly.

         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 Rights Certificate or
certificate for Common Stock 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 or acknowledged, by the proper Person or Persons.

         Section 20. 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 corporate
trust business 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 22 hereof. In case at
the time such successor Rights Agent shall succeed to the agency created by
this Agreement, any of the Rights 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 Rights
Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights Certificates either in the name of the predecessor or
in the 

                                     -21-
<PAGE>   25

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

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

         Section 21. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Rights Certificates,
by their acceptance thereof, shall be bound:

         (a) The Rights Agent may consult with legal counsel selected by it
(who may be legal counsel for the Company), 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
(including, without limitation, the identity of any Acquiring Person) 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 the Chairman of the Board, any Vice
Chairman of the Board, any President, any Vice President, the Treasurer, any
Assistant Treasurer, the Secretary or any Assistant 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.

         (c) The Rights Agent shall be liable hereunder 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 Rights
Certificates (except as to the fact that it has countersigned the Rights
Certificates) 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 Rights 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 Rights Certificate; nor shall
it be responsible for any adjustment required under the provisions of Section
11 or 13 hereof or responsible for the manner, method or amount of any such
adjustment or the ascertaining of the existence of facts that would require any


                                     -22-
<PAGE>   26

such adjustment (except with respect to the exercise of Rights evidenced by
Rights Certificates after actual notice of any such adjustment); nor shall it
be responsible for any determination by the Board of Directors of the Company
of the current market value of the Rights or Preferred Stock or Common Stock
pursuant to the provisions of Section 15 hereof; nor shall it by any act
hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any shares of Preferred Stock or other
securities to be issued pursuant to this Agreement or any Rights Certificate or
as to whether any shares of Preferred Stock or other securities will, when so
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 and
certificates delivered pursuant to any provision hereof from the Chairman of
the Board, any Vice Chairman of the Board, any President, any Vice President,
the Secretary, any Assistant Secretary, the Treasurer or any Assistant
Treasurer of the Company, and is authorized to apply to such officers for
advice or instructions in connection with its duties, and it shall not be
liable for any action taken or suffered to be taken by it in good faith in
accordance with instructions of any such officer.

         (h) The Rights Agent and any shareholder, 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, omission, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company or to the holders of
the Rights resulting from any such act, omission, default, neglect or
misconduct, provided reasonable care was exercised in the selection and
continued employment thereof.

         (j) No provision of this Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of its rights if
there shall be reasonable grounds for believing that repayment of such funds or
adequate indemnification against such risk or liability is not reasonably
assured to it.

         (k) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed or indicates an affirmative response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to
such requested exercise of transfer without first consulting with the Company.

         Section 22. 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 Stock and Preferred Stock by registered or certified mail,
and to holders of the Rights Certificates by first-class mail at the expense of
the Company. 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
Stock and Preferred Stock by registered or certified mail, and to the holders
of the Rights 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
Rights Certificate (who shall, with such notice, submit his Rights Certificate
for inspection by the Company), then the registered holder of any Rights
Certificate 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) a corporation
organized and doing business under the laws of the United States or of any
state of the United States, in good standing, that is authorized under such
laws to exercise corporate trust powers and is subject to supervision or
examination by federal or state authority and that has at the time of its
appointment as Rights Agent a combined capital and surplus of at least
$50,000,000 or (b) an affiliate of a corporation described in clause (a) of
this sentence. 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; 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 Stock and Preferred Stock, and mail a notice thereof in
writing to the registered holders of the Rights Certificates. Failure to give
any notice provided for in this Section 22, 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 23. Issuance of New Rights Certificates. Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights 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 per share and the number or kind or
class of shares or other securities or property purchasable under the Rights
Certificates made in accordance with the provisions of this Agreement.

         Section 24. Redemption and Termination.

                  (a) (i) The Board of Directors of the Company may, at its
         option, at any time prior to the earlier of (x) ten days after a
         person becomes an Acquiring Person or (y) 5:00 P.M., Houston time, on
         the Final Expiration Date, redeem all but not less than all of the
         then outstanding Rights at a redemption price of $.02 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")


                                     -24-
<PAGE>   28

                  (ii) In addition, the Board of Directors of the Company may
         redeem all, but not less than all, of the then outstanding Rights at
         the Redemption Price following the occurrence of a Stock Acquisition
         Date but prior to any event described in Section 13(a) either (x) in
         connection with any event specified in Section 13(a) in which all
         holders of Common Stock are treated alike and not involving (other
         than as a holder of Common Stock being treated like all other such
         holders) an Acquiring Person or an Affiliate or Associate of an
         Acquiring Person or any other Person in which such Acquiring Person,
         Affiliate or such Associate has any interest, or any other Person
         acting directly or indirectly on behalf of or in association with any
         such Acquiring Person, Affiliate or Associate, or (y) following the
         occurrence of an event set forth in, and the expiration of any period
         during which the holder of Rights may exercise the rights under,
         Section 11(a)(ii) if and for as long as the Acquiring Person is not
         thereafter the Beneficial Owner of securities representing 20% or more
         of the Voting Power, and at the time of redemption there are no other
         persons who are Acquiring Persons.

         (b) In the case of a redemption permitted under Section 24(a)(i),
immediately upon the action of the Board of Directors of the Company ordering
the redemption of the Rights, evidence of which shall have been filed with the
Rights Agent 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. In the case of a
redemption permitted only under Section 24(a)(ii), evidence of which shall have
been filed with the Rights Agent, the right to exercise the Rights will
terminate and represent only the right to receive the Redemption Price only
after ten Business Days following the giving of notice of such redemption to
the holders of such Rights if no event set forth in Section 11(a)(ii) shall
have occurred, and, if such event shall have occurred, upon the later of ten
Business Days following the giving of such notice or the expiration of any
period during which the rights under Section 11(a)(ii) may be exercised. Within
ten days after the action of the Board of Directors ordering any such
redemption of the Rights, the Company shall give notice of such redemption to
the Rights Agent and the holders of the then outstanding Rights by mailing such
notice to the Rights Agent and to all such holders 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 Agent for the Common
Stock. Any notice that 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.

         (c) In the case of a redemption permitted under Section 24(a)(i) or
(ii), the Company may, at its option, discharge all of its obligations with
respect to the Rights by (i) issuing a press release announcing the manner of
redemption of the Rights and (ii) mailing payment of the Redemption Price to
the registered holders of the Rights at their last addresses as they appear on
the registry books of the Rights Agent or, prior to the Distribution Date, on
the registry books of the Transfer Agent of the Common Stock, and upon such
action, all outstanding Rights Certificates shall be null and void without any
further action by the Company.

         Section 25. Notice of Certain Events. In case the Company shall
propose (a) to pay any dividend payable in stock of any class to the holders of
Preferred Stock or to make any other distribution to the holders of Preferred
Stock (other than a regular quarterly cash dividend out of earnings or retained
earnings of the Company) or (b) to offer to the holders of Preferred Stock
rights or warrants to subscribe for or to purchase any additional shares of
Preferred Stock or shares of stock 


                                     -25-
<PAGE>   29

of any class or any other securities, rights or options, or (c) to effect any
reclassification of its Preferred Stock (other than a reclassification
involving only the subdivision of outstanding shares of Preferred Stock), or
(d) 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 more than 50% of the
assets or earning power of the Company and its subsidiaries (taken as a whole)
to, any other Person, or (e) to effect the liquidation, dissolution or winding
up of the Company, then, in each such case, the Company shall give to each
holder of a Rights Certificate, in accordance with Section 26 hereof, a notice
of such proposed action, that shall specify the record date for the purposes of
such stock dividend, 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 shares of Preferred Stock, if any such date is to
be fixed, and such notice shall be so given in the case of any action covered
by clause (a) or (b) above at least 20 days prior to the record date for
determining holders of the shares of Preferred Stock for purposes of such
action, and in the case of any such other action, at least 20 days prior to the
date of the taking of such proposed action or the date of participation therein
by the holders of the shares of Preferred Stock, whichever shall be the
earlier.

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

         Section 26. Notices. Notices or demands authorized by this Agreement

Section 27, the Rights Agent shall execute such supplement or amendment unless
the Rights Agent shall have determined in good faith that such supplement or
amendment would adversely affect its interests under this Agreement. Prior to
this Distribution Date, the interests of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Stock.

         Section 28. Determination and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common
Stock or any other securities of which any Person is the Beneficial Owner,
shall be made in accordance with the last sentence of Rule 13d-3(d)(l)(i) of
the General Rules and Regulations under the Exchange Act as in effect on the

exclusive power and authority to administer this Agreement and to exercise all

without limitation, the right and power to (i) interpret the provisions of this
Agreement, and (ii) make all determinations deemed necessary or advisable for
the administration of this Agreement (including a determination to redeem or
not redeem the Rights or to amend the Agreement). All such actions,
calculations, interpretations and determinations (including, for purposes of
clause (y) below, all omissions with respect to the foregoing) that are done or
made by the Board in good faith, shall (x) be final, conclusive and binding on
the Company, the Rights Agent, the holders of the Rights Certificates and all
other parties, and (y) not subject the Board to any liability to the holders of
the Rights Certificates.

shall be construed to give to any person or corporation other than the Company,
the Rights Agent and the registered holders of the Rights Certificates (and,
prior to the Distribution Date, the Common Stock) any legal or equitable right,
remedy or claim under this Agreement; but this Agreement shall be for the sole
and 


                                     -27-
<PAGE>   31

exclusive benefit of the Company, the Rights Agent and the registered
holders of the Rights Certificates (and, prior to the Distribution Date, the
Common Stock).

         Section 31. 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
