Item 5.  Other Events

        On February 4, 1999 the Board of Directors of Kaufman and Broad Home
Corporation (the "Company") declared a dividend of one preferred stock purchase
right (a "Right") for each share of common stock of the Company, par value $1.00
per share (the "Common Stock"), and each share of Special Common Stock of the
Company, par value $1.00 per share (the "Special Common Stock";



<PAGE>   2

together with the Common Stock, the "Voting Stock"). No shares of Special Common
Stock are currently outstanding. The dividend will be issued to stockholders of
record as of the close of business on March 5, 1999. Rights will be issued with
Voting Securities issued after March 5, 1999 and before the Distribution Date
(as defined below). Each Right represents the right to purchase one
one-hundredth (1/100th) of a share of Series A Participating Cumulative
Preferred Stock ("Preferred Stock") of the Company at a price of $135.00 (as the
same may be adjusted, the "Exercise Price"). The description and terms of the
Rights are set forth in a Rights Agreement (as the same may be amended from time
to time, the "Rights Agreement") dated as of February 4, 1999, between the
Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the
"Rights Agent"). The Rights replace the Preferred Stock purchase rights issued
in 1989 under the Company's Rights Agreement dated February 21, 1989, which will
expire on March 7, 1999.

        In connection with adopting the Rights Agreement, the Board of Directors
of the Company also directed its Nominating and Corporate Governance Committee,
which consists solely of independent directors, to conduct a regular review of
the Rights Agreement and its effect on the best interests of the Company and its
shareholders at least every three years.

        The summary description of the Rights set out below does not purport to
be complete, and is qualified in its entirety by reference to the Rights
Agreement which is filed as an exhibit to this report and is hereby incorporated
herein by reference.

        The Rights will be evidenced by certificates for the Voting Stock until
the earlier to occur of (i) 10 days following a public announcement that a
person or group of affiliated or associated persons (with certain exceptions, an
"Acquiring Person") has acquired beneficial ownership of Voting Stock entitled
to 15% or more of the outstanding shares of Voting Stock or (ii) 10 business
days following the commencement of a tender offer or exchange offer the
consummation of which would result in a person or group of affiliated or
associated persons becoming an Acquiring Person (the earlier of such dates being
called the "Distribution Date").

        On January 7, 1999, the Company acquired substantially all of the
homebuilding assets of the Lewis Homes group of companies. As partial
consideration for the acquisition, the Company issued 7,886,686 shares of Common
Stock to certain members of the Lewis family, a former officer of Lewis Homes
and entities controlled by them (the "Lewis Holders"). As a result, the Lewis
Holders currently hold in the aggregate approximately 16.5% of the outstanding
Common Stock. Accordingly, the Rights Agreement provides that the Lewis Holders
(and certain permitted transferees) will not become Acquiring Persons as a
result of the holdings of or acquisitions by any of the Lewis Holders, so long
as their aggregate ownership remains below 17% of the outstanding Voting Stock.
In the event the aggregate ownership of the Lewis Holders falls below 15.5% of
the outstanding shares of the Voting Stock, the Lewis Holders exempt percentage
will become 16% of the outstanding shares of the Voting Stock. In the event the
aggregate ownership of the Lewis Holders falls below 14.5% of the outstanding
shares of the Voting Stock, the Lewis Holders' exemption will terminate.

        The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights): (i) the Rights will be
transferred only with the Voting Stock; (ii) Voting Stock certificates will
contain a notation referencing the Rights and Rights Agreement (the notation



<PAGE>   3

on already outstanding Voting Stock certificates referring to the Company's
prior Rights Agreement will be deemed to refer to the new Rights); and (iii) the
surrender for transfer of any certificates for shares of Voting Stock will also
constitute the transfer of the Rights associated with the shares of Voting Stock
represented by such certificate. As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Voting Stock as of the
close of business on the Distribution Date and thereafter such separate Right
Certificates alone will evidence the Rights.

        The Rights are not exercisable until the Distribution Date. The Rights
will expire on March 5, 2009 (the "Final Expiration Date"), unless the Rights
are earlier redeemed or exchanged by the Company, in each case as described
below.

        The Exercise Price payable, and the number of shares of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution, for example, in the
event of a stock dividend on, or a subdivision, combination or reclassification
of, the Voting Stock.

        If any person or group of affiliated or associated persons becomes an
Acquiring Person, each holder of a Right (other than Rights beneficially owned
by the Acquiring Person, which become void) will have the right to receives upon
exercise and payment of the then current Exercise Price, that number of shares
of Preferred Stock having a market value of two times the Exercise Price.

        If, after a person or group has become an Acquiring Person, the Company
is acquired in a merger or other business combination transaction, or 50% or
more of its consolidated assets or earning power are sold, proper provision will
be made so that each holder of a Right (other than the Acquiring Person, whose
Rights will become void) will thereafter have the right to receive, upon
exercise at the then current Exercise Price, that number of shares of common
stock of the person with whom the Company has engaged in the foregoing
transaction (or its parent), which at the time of such transaction will have a
market value of two times the Exercise Price.

        In lieu of exercise, the Board of Directors of the Company may exchange
the Rights (other than Rights owned by the Acquiring Person, which become void),
in whole or in part, for shares of Voting Stock at an exchange ratio of one
share of Voting Stock per Right (as appropriately adjusted to reflect changes in
the Voting Stock after the date of the Rights Agreement).

        No fractional shares of Preferred Stock will be issued, other than
fractions which are integral multiples of one hundreths of a share, which may,
at the election of the Company, be evidenced by depositary receipts. In lieu of
any other fractional interest, an adjustment in cash will be made based on the
market price of the Preferred Stock.

        At any time prior to ten days after an Acquiring Person becomes such (or
such later date as the Board of Directors of the Company may determine), the
Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.005 per Right, subject to adjustment (the "Redemption
Price"). The redemption of the Rights may be made effective at such time, on
such basis and with such conditions as the Board of Directors of the Company may
establish. Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and




<PAGE>   4

the only right of the holders of Rights will be to receive the Redemption Price.
The Rights may be amended by the Company to the extent and on the conditions set
out in the Rights Agreement.

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

        The Rights have effects that will render difficult an acquisition of the
Company without the approval of the Company's Board of Directors. The Rights
will cause substantial dilution to a person or group of affiliated or associated
persons that attempts to acquire the Company without conditioning the offer on
substantially all the Rights being acquired. The Rights will not interfere with
any merger or other business combination approved by the Board of Directors may,
at its option, at any time prior to a person or group becoming an Acquiring
Person, redeem the then outstanding Rights at the Redemption Price.

                                RIGHTS AGREEMENT



               This Rights Agreement dated as of February 4, 1999, between
Kaufman and Broad Home Corporation, a Delaware corporation (the "Company"), and
ChaseMellon Shareholder Services, L.L.C., a limited liability company registered
in the State of New Jersey, Rights Agent (the "Rights Agent"),

                               W I T N E S S E T H

               WHEREAS, on February 4, 1999 the Board of Directors of the
Company authorized and declared a dividend distribution of one preferred stock
purchase right (hereafter referred to as a "Right") for each share of the Common
Stock outstanding at the close of business on March 5, 1999, immediately after
the expiration of the exercisability of preferred stock purchase rights under
that certain Rights Agreement (the "Prior Rights Agreement") dated February 21,
1989 between the Company and Security Pacific National Bank (or its successor),
as rights agent (hereinafter referred to as the "Record Date") and has
authorized the issuance of one Right (as such number may hereafter be adjusted
pursuant to the provisions of Section 11(p) hereof) in respect of each share of
Common Stock and each share of Special Common Stock that shall become
outstanding after the Record Date (whether originally issued or delivered from
the Company's treasury) and on or prior to the earlier of the Distribution Date
or the Expiration Date, each Right representing the right to purchase one
one-hundredth of a share of Preferred Stock having the rights, powers and
preferences set forth in the Certificate of Designation attached hereto as
Exhibit A, upon the terms and subject to the conditions hereinafter set forth
(the "Rights");

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

               Section 1.  Certain Definitions.  For purposes of this Agreement,
the following terms have the meanings indicated;

               "Acquiring Person" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of shares of Common Stock or Special Common Stock entitled to 15% or more of the
aggregate votes entitled to be cast by all shares of Common Stock and Special
Common Stock then outstanding, but shall not include (i) the Company or any
Subsidiary of the Company, (ii) any employee benefit plan of the Company or any
Subsidiary of the Company, or any entity organized, appointed or established for
or pursuant to the terms of any such plan, (iii) the Exempt Shareholders, or
(iv) any Person who has become such a Beneficial Owner solely because (A) of a
change in the aggregate number of shares of Common Stock or Special Common Stock
outstanding since the last date on which such Person acquired Beneficial
Ownership of any shares of Common Stock or Special Common Stock or (B) (1) it
acquired such Beneficial Ownership in the good faith belief that such
acquisition would not (x) cause such Beneficial Ownership to exceed 15% of the
shares of Common Stock or Special Common Stock then outstanding and such Person
relied in good faith in computing the percentage of its Beneficial Ownership on
publicly filed reports or documents of the Company 



<PAGE>   4

which are inaccurate or out-of-date or (y) otherwise cause a Distribution Date
or the adjustment provided for in Section 11(a) to occur, or (2) it otherwise
inadvertently acquired such Beneficial Ownership. Notwithstanding clause (iii)
of the prior sentence, if any Person that is not an Acquiring Person due solely
to such clause (iii) does not reduce its percentage of Beneficial Ownership of
shares of Common Stock or Special Common Stock to less than 15% by the Close of
Business on the fifth Business Day after notice from the Company (the date of
notice being the first day) that such Person's Beneficial Ownership of shares of
Common Stock or Special Common Stock equals or exceeds 15%, such Person shall,
at the end of such five Business Day period, become an Acquiring Person (and
such clause (iii) shall no longer apply to such Person). For purposes of this
definition, the determination whether any Person acted in "good faith" or
"inadvertently" shall be conclusively determined by the Board of Directors of
the Company.

               "Agreement" shall mean this Agreement, as it may be amended from
time to time.

               "Affiliate" and "Associate" shall have the respective meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under
the Exchange Act.

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

               (i) which such Person or any of such Person's Affiliates or
        Associates, directly or indirectly, beneficially owns (as determined
        pursuant to Section 13(d) of the Exchange Act and Regulation 13D-G
        thereunder (or any comparable or successor law or regulation), as in
        effect on the date of this Agreement) or has the right to dispose of;

               (ii) which such Person or any of such Person's Affiliates or
        Associates, directly or indirectly, has (A) the right to acquire
        (whether such right is exercisable immediately or only after the passage
        of time) pursuant to any agreement, arrangement or understanding
        (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, that a Person shall not be deemed the "Beneficial
        Owner" of or to "beneficially own" under this clause (A) securities
        tendered pursuant to a tender or exchange offer made by or on behalf of
        such Person or any of such Person's Affiliates or Associates until such
        tendered securities are accepted for payment or exchange; or (B) the
        right to vote, including pursuant to any agreement, arrangement or
        understanding (whether or not in writing); provided, that a Person shall
        not be deemed the "Beneficial Owner" of or to "beneficially own" any
        security under this clause (B) as a result of an agreement, arrangement
        or understanding to vote such security if such agreement, arrangement or
        understanding (1) arises solely from a revocable proxy or consent given
        in response to a public proxy or consent solicitation made pursuant to,
        and in accordance with, the applicable rules and regulations under the
        Exchange Act and (2) is not also then reportable by such Person on
        schedule 13D under the Exchange Act (or any comparable or successor
        report); or

               (iii) which are beneficially owned, directly or indirectly, by

               Section 3.  Issue of Right Certificates.

               (a) Until the earlier of (i) the Close of Business on the tenth
day after the Stock Acquisition Date or (ii) the Close of Business on the tenth
Business Day after the date of the commencement of a tender or exchange offer by
any Person (other than (1) the Company or any Subsidiary of the Company or (2)
any employee benefit plan of the Company or of any Subsidiary of the Company, or
any Person or entity organized, appointed or established for or pursuant to the
terms of any such plan) if, upon consummation thereof, such Person would be an
Acquiring Person (including any such date which is after the date of this
Agreement and prior to the issuance of the Rights; the earlier of such dates
being herein referred to as the "Distribution Date"), (x) the Rights will be
evidenced (subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock and the Special Common Stock registered in the
names of the holders of the Common Stock or Special Common Stock, as the case
may be (which certificates for Common Stock and Special Common Stock shall be
deemed also to be Right Certificates) and not by separate Right Certificates,
and (y) the Rights will be transferable only in connection with the transfer of
the underlying shares of Common Stock and Special Common Stock, as the case may
be. As soon as practicable after the Company has notified the Rights Agent of
the occurrence of the Distribution Date, the Rights Agent will send, by
first-class, insured, postage prepaid mail, to each record holder of the Common
Stock and Special Common Stock as of the Close of Business on the Distribution
Date, at the address of such holder shown on the records of the Company, one or
more right certificates, in substantially the form of Exhibit B hereto (the
"Right Certificates"), evidencing one Right for each share of Common Stock or
Special Common Stock, as the case may be, so held, subject to adjustment as
provided herein. Right Certificates issued in respect of shares of Special
Common Stock (or upon transfer of any such Right Certificates) will contain
appropriate notations thereon in regard thereto. If an adjustment in the number
of Rights per share of Common Stock and Special Common Stock has been made
pursuant to Section 11(p) hereof, at the time of distribution of the Right
Certificates, the Company shall make the necessary and appropriate rounding
adjustments (in accordance with Section 14(a) hereof) so that Right Certificates
representing only whole numbers of Rights are distributed and cash is paid in
lieu of any fractional Rights. As of and after the Distribution Date, the Rights
will be evidenced solely by such Right Certificates.

               (b) With respect to certificates for the Common Stock and Special
Common Stock outstanding as of the Record Date, until the Distribution Date (or
the earlier redemption, expiration or termination of the Rights) the Rights will
be evidenced by such certificates for the Common Stock or Special Common Stock,
as the case may be, registered in the names of the holders of such stock and the
registered holders of such stock shall also be registered holders of the
associated Rights. Until the Distribution Date (or the earlier redemption,
expiration or termination of the Rights), the transfer of any of the
certificates for the Common Stock or Special Common Stock, as the case may be,
in respect of which Rights have been issued shall also constitute the transfer
of the Rights associated with the stock represented by such certificates.

               (c) Rights shall be issued in respect of all shares of Common
Stock and Special Common Stock which are issued (whether upon exercise or
conversion of securities exercisable or convertible into such stock, or
otherwise) or are delivered out of treasury at or after the Close of Business on
the Record Date but prior to the Distribution Date (or the earlier redemption,

<PAGE>   8

expiration or termination of the Rights). Certificates for the Common Stock and
Special Common Stock issued (whether upon exercise or conversion of securities
exercisable or convertible into such stock, or otherwise) or delivered out of
treasury after the Record Date but prior to the earlier of the Distribution Date
or the redemption, expiration or termination of the Rights shall be deemed also
to be certificates for Rights and shall have impressed on, printed on, written
on or otherwise affixed to them the following legend:

               This certificate also evidences and entitles the holder hereof to
               certain Rights as set forth in a Rights Agreement between Kaufman
               and Broad Home Corporation and ChaseMellon Shareholder Services,
               L.L.C., dated as of February 4, 1999, as it may be amended from
               time to time (the "Rights Agreement"), the terms of which are
               hereby incorporated herein by reference and a copy of which is on
               file at the principal executive offices of the Company. Under
               certain circumstances, as set forth in the Rights Agreement, such
               Rights may be redeemed, may expire, or may be evidenced by
               separate certificates and no longer be evidenced by this
               certificate. The Company will mail to the holder of this
               certificate a copy of the Rights Agreement without charge after
               receipt of a written request therefor. Under certain
               circumstances set forth in the Rights Agreement, Rights issued
               to, or held by, any Person who is, was or becomes an Acquiring
               Person or an Affiliate or Associate thereof (as such terms are
               defined in the Rights Agreement), whether currently held by or on
               behalf of such Person or by any subsequent holder, shall be null
               and void and may not be transferred.

Certificates for Common Stock or Special Common Stock bearing a legend similar
to the foregoing pursuant to the Prior Rights Agreement may also be used until
the supply of such certificates is exhausted. With respect to such certificates
containing the foregoing legend or a similar legend pursuant to the Prior Rights
Agreement, until the Distribution Date (or the earlier redemption, expiration or
termination of the Rights) the Rights associated with the Common Stock or
Special Common Stock represented by such certificates shall be evidenced by such
certificates alone, and the transfer of any of such certificates shall also
constitute the transfer of the Rights associated with the Common Stock or
Special Common Stock, as the case may be, represented by such certificates.

               (d) Notwithstanding paragraphs (b) and (c), the omission of a
legend shall not affect the enforceability of any part of this Agreement or the
rights of any holder of Rights.

               (e) No Right Certificate shall be issued pursuant to this Section
3 that represents Rights beneficially owned by an Acquiring Person, or any
Associate or Affiliate thereof, or any transferee of an Acquiring Person or
Associate or Affiliate thereof, whose Rights would be void pursuant to the
provisions of Section 7(e) hereof. No Right Certificate shall be issued at any
time upon the transfer of any Rights to an Acquiring Person, Associate or
Affiliate thereof, or transferee of an Acquiring Person or Associate or
Affiliate thereof, whose Rights would be void pursuant to the provisions of
Section 7(e) hereof. Any right Certificate delivered to the Rights Agent for
transfer to any such Person whose Rights would be void pursuant to the
provisions of Section 7(e) hereof shall be canceled.

               Section 4.  Form of Right Certificates.

               (a) The Right Certificates (and the forms of election to
purchase, certification, and assignment to be printed on the reverse thereof)
shall be substantially in the form of 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 which do not affect the
duties or responsibilities of the Rights Agent and as are not inconsistent with
the provisions of this Agreement, or as may be required to comply with any
applicable law, rule or regulation 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 22 hereof, the Right
Certificates on their face shall entitle the holders thereof to purchase such
number of one one-hundredths of a share of Preferred Stock as shall be set forth
therein at the price set forth therein, as the same may from time to time be
adjusted according to the terms of this Agreement (such exercise price per one
one-hundredth of a share, the "Purchase Price"), but the amount and type of
securities purchasable upon the exercise of each Right and the Purchase Price
thereof shall be subject to adjustment as provided herein.

               (b) Notwithstanding any other provision of this Agreement, if any
Right Certificate is issued pursuant to Section 3 or Section 22 hereof that
represents Rights beneficially owned by (i) an Acquiring Person or any Associate
or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person
(or of any such Associate or Affiliate) who becomes a transferee after the
Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which the Board of Directors of the Company has determined is part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of Section 7(e) hereof, or any Right Certificate is issued pursuant to
Section 6 or Section 11 hereof upon transfer, exchange, replacement or
adjustment of any other Right Certificate referred to in this sentence, such
Right Certificate shall contain (to the extent feasible) the following legend:

               The Rights represented by this Right Certificate are or were
               beneficially owned by a Person who was or became an Acquiring
               Person or an Affiliate or Associate of an Acquiring Person (as
               such terms are defined in the Rights Agreement). Accordingly,
               this Right Certificate and the Rights represented hereby may be
               or may become null and void in the circumstances specified in
               Section 7(e) of such Agreement.

               Notwithstanding the foregoing in this Section 4(b), the omission
of such a legend shall not affect the enforceability of any part of this
Agreement.

               Section 5.  Countersignature and Registration.
<PAGE>   10

               (a) The Right Certificates shall be executed on behalf of the
Company by its Chairman of the Board, its 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 Right Certificates shall be manually countersigned by the Rights
Agent and shall not be valid for any purpose unless so countersigned. In case
any officer of the Company whose manual or facsimile signature is affixed to the
Right Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Right Certificates, nevertheless, may be countersigned by the Rights Agent,
issued and delivered with the same force and effect as though the Person who
signed such Right Certificates had not ceased to be such officer of the Company.
Any Right Certificate may be signed on behalf of the Company by any Person who,
at the actual date of the execution of such Right Certificate, shall be a proper
officer of the Company to sign such Right Certificate, although at the date of
the execution of this Rights Agreement any such Person was not such an officer.

               (b) Following the Distribution Date and receipt by the Rights
Agent of all necessary information, the Rights Agent will keep or cause to be
kept, at its principal office or offices designated as the appropriate place for
surrender of Right Certificates upon exercise or transfer, books for
registration and transfer of the Right Certificates issued hereunder. Such books
shall show the names and addresses of the respective holders of the Right
Certificates, the number of Rights evidenced on its face by each of the Right
Certificates, the certificate number of each of the Right Certificates, the date
of each of the Right Certificates, and any other information deemed appropriate
by the Rights Agent and/or the Company.

               Section 6.  Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.

               (a) Subject to the provisions of Section 3(e), Section 4(b),
Section 7(e) and Section 14 hereof, at any time after the Close of Business on
the Distribution Date, and at or prior to the Close of Business on the
Expiration Date (as such term is defined in Section 7(a) hereof), any Right
Certificate or Right Certificates may be transferred, split up, combined or
exchanged for another Right Certificate or Right Certificates, entitling the
registered holder to purchase a like number of one one-hundredths of a share of
Preferred Stock (or, following a Triggering Event, Common Stock, Special Common
Stock, other securities, cash or assets, as the case may be) as the Right
Certificate or Right Certificates surrendered then entitled such holder (or
former holder in the case of a transfer) to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Right Certificate or
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the principal office or offices
of the Rights Agent designated for such purpose. Neither the Rights Agent nor
the Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered Right Certificate until the registered holder
shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Right Certificate and shall have provided
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. Thereupon the Rights Agent shall, subject to Section 3(e),
Section 4(b), Section 7(e) and Section 14 hereof, countersign and deliver 
<PAGE>   11

to the Person entitled thereto a Right Certificate or Right Certificates, as the
case may be, as so requested. The Company may require payment of a sum
sufficient to cover any tax or charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates. The Rights
Agent shall have no duty or obligation under this Section unless it is
reasonably satisfied that all such taxes and/or charges have been paid.

               (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security satisfactory to them, and, at the Company's request, reimbursement to
the Company and the Rights Agent of all reasonable expenses incidental thereto,
and upon surrender to the Rights Agent and cancellation of the Right Certificate
if mutilated, the Company will make and deliver a new Right Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

               (a) Subject to Section 7(e) hereof, the registered holder of any
Right Certificate may exercise the Rights evidenced thereby (except as otherwise
provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Right Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly and properly executed, to the
Rights Agent at the office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price with respect to
the total number of one one-hundredths of a share of Preferred Stock (or other
securities or property, as the case may be) as to which such surrendered Rights
are then exercisable, at or prior to the earliest of (i) the Close of Business
on March 5, 2009 (the "Final Expiration Date"), (ii) the time at which the
Rights are redeemed as provided in Section 23 hereof, or (iii) the time at which
the Rights are exchanged as provided in Section 24 hereof (the earliest of (i),
(ii) and (iii) being herein referred to as the "Expiration Date").

               (b) The Purchase Price for each one one-hundredth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $135. The
Purchase Price and the number of shares of Preferred Stock (or other securities
or property, as the case may be) to be acquired upon exercise of a Right shall
be subject to adjustment from time to time as provided herein and shall be
payable in lawful money of the United States of America in accordance with
paragraph (c) below.

               (c) Upon receipt of a Right Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly and
properly executed, accompanied by payment, with respect to each Right so
exercised, of the Purchase Price per one one-hundredth of a share of Preferred
Stock (or other securities or property, as the case may be) to be purchased, and
an amount equal to any applicable tax or charge, in cash, or in the form of a
certified check or money order made payable to the order of the Company, the
Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly (i)(A)
requisition from any transfer agent of the Preferred Stock (or make available,
if the Rights Agent is the transfer agent therefor) certificates for the total
number of one one-hundredths of a share of Preferred Stock to be purchased and
the 
<PAGE>   12

Company hereby irrevocably authorizes its transfer agent to comply with all
such requests, or (B) if the Company shall have elected to deposit the total
number of shares of Preferred Stock issuable upon exercise of the Rights
hereunder with a depositary agent, requisition from the depositary agent
depositary receipts representing such number of one one-hundredths 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 will direct the
depositary agent to comply with such request, (ii) requisition from the Company
the amount of cash, if any, to be paid in lieu of issuance of fractional shares
in accordance with Section 14 hereof, (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 Right Certificate, registered in such
name or names as may be designated by such holder and (iv) after receipt
thereof, promptly deliver such cash, if any, to or upon the order of the
registered holder of such Right Certificate. If the Company is obligated to
issue other securities (including Common Stock or Special Common Stock) of the
Company, pay cash or distribute other property pursuant to Section 11(a) hereof,
the Company will make all arrangements necessary so that such other securities,
cash or other property are available for distribution by the Rights Agent, if
and when appropriate.

               (d) In case the registered holder of any Right Certificate shall
exercise less than all the Rights evidenced thereby, a new Right Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent and delivered to, or upon the order of, the registered
holder of such Right Certificate, registered in such name or names as may be
designated by such holder, subject to the provisions of Section 14 hereof.

               (e) Notwithstanding anything in this Agreement to the contrary,
from and after the first occurrence of a Section 11(a)(ii) Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes such or (iii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee prior to or concurrently with
the Acquiring Person becoming such and receives such Rights pursuant to either
(A) a transfer (whether or not for consideration) from the Acquiring Person to
holders of equity interests in such Acquiring Person or to any Person with whom
the Acquiring Person has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which the Board of Directors
of the Company has determined is part of a plan, arrangement or understanding
which has as a primary purpose or effect the avoidance of this Section 7(e),
shall become null and void without any further action and no holder of such
Rights shall have any rights whatsoever with respect to such Rights, whether
under any provision of this Agreement or otherwise. The Company shall use all
reasonable efforts to insure that the provisions of this Section 7(e), Section
3(e), and Section 4(b) hereof are complied with, but shall have no liability to
any holder of Right Certificates or other Person as a result of its failure to
make any determinations with respect to an Acquiring Person or its Affiliates
and Associates or any transferee of any of them hereunder. The Rights Agent
shall have no duty or obligation under this Section to insure that the
provisions of this Section 7(e), Section 3(e) and Section 4(b) hereof are
complied with.

               (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 
<PAGE>   13

registered holder of Rights upon the occurrence of any purported exercise as set
forth in this Section 7 unless such registered holder shall have (i) completed
and signed the certificate contained in the form of election to purchase set
forth on the reverse side of the Right Certificate surrendered for such exercise
and (ii) provided such additional evidence of the identity of the Beneficial
Owner (or former Beneficial Owner) or Affiliates or Associates thereof as the
Company or the Rights Agent shall reasonably request.

               Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Agreement. The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all cancelled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such cancelled Right Certificates, and in such
case shall deliver a certificate of destruction thereof to the Company.

               Section 9.  Reservation and Availability of Capital Stock.

               (a) The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares of
Preferred Stock (and, following the occurrence of a Triggering Event, out of its
authorized and unissued shares of Common Stock, Special Common Stock or other
securities or out of its authorized and issued shares held in its treasury) the
number of shares of Preferred Stock (and, following the occurrence of a
Triggering Event, Common Stock, Special Common Stock or other securities) that,
as provided in this Agreement, including Section 11(a)(iii) hereof , will be
sufficient to permit the exercise in full of all outstanding Rights.

               (b) So long as the Preferred Stock (and, following the occurrence
of a Triggering Event, Common Stock, Special Common Stock, or other securities)
issuable and deliverable upon the exercise of Rights may be listed on any
national securities exchange or is eligible for quotation on NASDAQ, or other
such system then in use, the Company shall use its best efforts to cause, from
and after such time as the Rights become exercisable, all shares reserved for
such issuance to be listed on such exchange or quoted on NASDAQ, or other such
system then in use, upon official notice of issuance upon such exercise.

               (c) The Company shall use its best efforts to (i) file, as soon
as practicable following the earliest date after the occurrence of a Section
11(a)(ii) Event as of which the consideration to be delivered by the Company
upon exercise of the Rights has been determined in accordance with Section
11(a)(iii) hereof, or as soon as is required by law following the Distribution
Date, as the case may be, a registration statement under the Securities Act of
1933, as amended (the "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 Act) until the earlier of (A) the date as
of 

<PAGE>   14

which the Rights are no long exercisable for such securities and (B) the date
of the expiration of the Rights. The Company will also take such action as may
be appropriate under, or to ensure compliance with, the securities or "Blue Sky"
laws of the various states in connection with the exercisability of the Rights.
The Company may temporarily suspend, for a period of time not to exceed 90 days
after the date set forth in clause (i) of the first sentence of this Section
9(c), the exercisability of the Rights in order to prepare and file such
registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect with prompt
notice thereof to the Rights Agent. Notwithstanding any such provision of this
Agreement to the contrary, the Rights shall not be exercisable in any
jurisdiction if the requisite qualification in such jurisdiction shall not have
been obtained, the exercise thereof shall not be permitted under applicable law
or a registration statement shall not have been declared effective.

               (d) The Company covenants and agrees that it will take all such
action as may be necessary to insure that all one one-hundredths of a share of
Preferred Stock (and, following the occurrence of a Triggering Event, Common
Stock, Special Common Stock or other securities) delivered upon exercise of
Rights shall, at the time of delivery of the certificates for such shares
(subject to payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable.

               (e) The Company further covenants and agrees that it will pay
when due and payable any and all taxes and charges which may be payable in
respect of the issuance or delivery of the Right Certificates and of any
certificates for one one-hundredths of a share of Preferred Stock (or Common
Stock, Special Common Stock or other securities, as the case may be) upon the
exercise of Rights. The Company shall not, however, be required to pay any tax
or charge which may be payable in respect of any transfer involved in the
transfer or delivery of Right Certificates to a Person other than, or the
issuance or delivery of a number of one one-hundredths of a share of Preferred
Stock (or Common Stock, Special Common Stock or other securities, as the case
may be) in respect of a name other than that of, the registered holder of the
Right Certificate evidencing Rights surrendered for exercise or to issue or
deliver any certificates for a number of one one-hundredths of a share of
Preferred Stock (or Common Stock, Special Common Stock or other securities, as
the case may be) in a name other than that of the registered holder upon the
exercise of any Rights until any such tax or charge shall have been paid (any
such tax or charge being payable by the holder of such Right Certificate at the
time of surrender) or until it has been established to the Company's
satisfaction that no such tax or charge is due.

               Section 10. Preferred Stock Record Date. Each Person (other than
the Company) in whose name any certificate for a number of one one-hundredths of
a share of Preferred Stock (or Common Stock, Special Common Stock or other
securities, as the case may be) is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of such fractional
shares of Preferred Stock (or Common Stock, Special Common Stock or other
securities, as the case may be) represented thereby on, and such certificate
shall be dated, the date upon which the Right Certificate evidencing such Rights
was duly surrendered and payment of the Purchase Price (and any applicable taxes
or charges) was made; provided, that if the date of such surrender and payment
is a date upon which the Preferred Stock (or Common Stock, Special Common Stock
or other securities, as the case may be) transfer books of the Company are
closed, 
<PAGE>   15

such Person shall be deemed to have become the record holder of such shares
(fractional or otherwise) on, and such certificate shall be dated, the next
succeeding Business Day on which the Preferred Stock (or Common Stock, Special
Common Stock or other securities, as the case may be) transfer books of the
Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Right Certificate shall not be entitled to any rights of a
stockholder 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 and kind 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) If the Company shall at any time after the date of this
        Agreement (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 Section 7(e) hereof, 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 Preferred Stock
        or capital stock, as the case may be, issuable on such date, shall be
        proportionately adjusted so that the holder of any Right exercised after
        such time shall be entitled to receive, upon payment of the aggregate
        adjusted Purchase Price then in effect, the aggregate number and kind of
        shares of Preferred Stock or capital stock, as the case may be, which,
        if such Right had been exercised immediately prior to such date and at a
        time when the Preferred Stock (or other capital stock, as the case may
        be) 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 which
        will require an adjustment under both this Section 11(a)(i) and Section
        11(a)(ii) hereof, 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) hereof.

               (ii) If any Person, alone or together with its Affiliates and
        Associates or otherwise, shall become an Acquiring Person, then proper
        provision shall promptly be made so that each holder of a Right, except
        as provided below and in Section 7(e) hereof, shall thereafter have the
        right to receive, upon exercise thereof at the then current Purchase
        Price in accordance with the terms of this Agreement, in lieu of
        Preferred Stock, such number of shares of Common Stock (or, in the case
        of Rights originally issued to a holder of Special Common Stock, shares
        of Special Common Stock) (such number of shares of Common Stock or
        Special Common Stock being referred to herein as the "Adjustment
        Shares") as shall equal the result obtained by (x) multiplying the then
        current Purchase Price by the number of one one-hundredths of a share of
        Preferred Stock for 

<PAGE>   16

        which a Right was exercisable immediately prior to the first occurrence
        of a Section 11(a)(ii) Event and (y) dividing that product (which,
        following such first occurrence, shall thereafter be referred to as the
        "Purchase Price" for each Right and for all purposes of this Agreement)
        by 50% of the current market price per share of the Common Stock
        (determined pursuant to Section 11(d) on the date of the first
        occurrence of a Section 11(a)(ii) Event); provided, 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). The Company shall not enter
        into any transaction of the kind listed in this subparagraph (ii) if at
        the time of such transaction there are any rights, warrants, instruments
        or securities outstanding or any agreements of arrangements which, as a
        result of the consummation of such transaction, would substantially
        diminish or otherwise eliminate the benefits intended to be afforded by
        the Rights.

               (iii) If the number of shares of Common Stock or Special Common
        Stock which are authorized by the Company's certificate of incorporation
        but not outstanding or reserved for issuance for purposes other than
        upon exercise of the Rights is not sufficient to permit the exercise in
        full of the Rights in accordance with the foregoing subparagraph (ii) of
        this Section 11(a), the Company shall: (A) determine the excess of (1)
        the value of the Adjustment Shares issuable upon the exercise of a Right
        (the "Current Value") over (2) the Purchase Price (such excess being
        referred to herein as the "Spread") and (B) with respect to each Right,
        make adequate provision to substitute for the Adjustment Shares, upon
        payment of the applicable Purchase Price, (1) cash, (2) a reduction in
        the Purchase Price, (3) Common Stock or Special Common Stock, as the
        case may be, or other equity securities of the Company (including,
        without limitation, shares, or units of shares, of preferred stock which
        the Board of Directors of the Company has deemed to have the same value
        as shares of Common Stock (such shares of preferred stock being referred
        to herein as "common stock equivalents")), (4) debt securities of the
        Company, (5) other assets or (6) any combination of the foregoing,
        having an aggregate value equal to the Current Value, where such
        aggregate value has been determined by the Board of Directors of the
        Company based upon the advice of a nationally recognized investment
        banking firm selected by the Board of Directors of the Company;
        provided, that if the Company shall not have made adequate provision to
        deliver value pursuant to clause (B) above within 30 days following the
        later of the first occurrence of a Section 11(a)(ii) Event and the first
        date that the right to redeem the Rights pursuant to Section 23 hereof
        shall expire, then the Company shall be obligated to deliver, upon the
        surrender for exercise of a Right and without requiring payment of the
        Purchase Price, shares of Common Stock or Special Common Stock, as the
        case may be, (in each case to the extent available) and then, if
        necessary, cash, securities or assets in the aggregate equal in value
        (as determined by the Board of Directors of the Company based upon the
        advice of a nationally recognized investment banking firm selected by
        the Board of Directors of the Company) to the Spread. If the Board of
        Directors of the Company shall determine in good faith that it is likely
        that sufficient additional shares of Common Stock or Special Common
        Stock, as the case may be, can be authorized for issuance upon exercise
        in full of the Rights, the 30 day period set forth above may be extended
        to the extent necessary, but not by more than 90 days following the
        first occurrence of a Section 11(a)(ii) Event, in order that the Company
        may seek stockholder approval for the authorization of such additional
        shares (such 
<PAGE>   17

        period, as it may be extended, being referred to herein as the
        "Substitution Period"). To the extent that the Company determines that
        some action is to be taken pursuant to the first or second sentences of
        this Section 11(a)(iii), the Company (x) shall provide, subject to
        Section 7(e) hereof, that such action shall apply uniformly to all
        outstanding Rights, and (y) may suspend the exercisability of the Rights
        until the expiration of the Substitution Period in order to seek any
        authorization of additional shares or to decide the appropriate form of
        distribution to be made pursuant to such first sentence 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, as well as a public announcement
        at such time as the suspension is no longer in effect, in each case with
        prompt notice thereof to the Rights Agent. For purposes of this Section
        11(a)(iii), the value of the Common Stock shall be the current market
        price (as determined pursuant to Section 11(d) hereof) per share of the
        Common Stock on the later of the date of the first occurrence of a
        Section 11(a)(ii) Event and the first date that the right to redeem the
        Rights pursuant to Section 23 hereof shall expire and the value of any
        "common stock equivalent" shall be deemed to have the same value as the
        Common Stock on such date.

               (b) In case the Company shall fix a record date for the issuance
of rights, options or warrants to all holders of Preferred Stock entitling them
to subscribe for or purchase (for a period expiring within 45 calendar days
after such record date) Preferred Stock (or securities having the same rights,
privileges and preferences as the shares of 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 or exercise price per share,
if a security convertible into or exercisable for Preferred Stock or equivalent
preferred stock) less than the current market price (as determined pursuant to
Section 11(d) hereof) per share of 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 prior to such 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 which the aggregate offering price of the total number of shares of
Preferred Stock or equivalent preferred stock so to be offered (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 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 by delivery of consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights Agent and the holders of Rights. 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 if such
rights or warrants are no so issued, the Purchase Price shall be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.
<PAGE>   18

               (c) In case 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 periodic 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
convertible securities, subscription rights or warrants (excluding those
referred to in Section 11(b) hereof), the Purchase Price to be in effect after
such record date shall be determined by multiplying the Purchase Price in effect
immediately prior to such record date by a fraction, the numerator of which
shall be the current market price (as determined pursuant to Section 11(d)
hereof) per share of Preferred Stock on such record date, less the fair market
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent) of the portion of the cash, assets or evidences of indebtedness so to be
distributed or of such convertible securities, subscription rights or warrants
applicable to one share of Preferred Stock and the denominator of which shall be
such current market price (as determined pursuant to Section 11(d) hereof) per
share of Preferred Stock. Such adjustments shall be made successively whenever
such a record date is fixed, and if such distribution is not so made, the
Purchase Price shall again be adjusted to be the Purchase Price which would then
be in effect if such record date had not been fixed.

               (d)(i) For the purpose of any computation hereunder, other than
        computations made pursuant to Section 11(a)(iii) hereof, the "current
        market price" per share of the Common Stock or Special Common Stock on
        any date shall be deemed to be the average of the daily closing prices
        per share of such Common Stock or Special Common Stock for the 30
        consecutive Trading Days (as such term is hereinafter defined)
        immediately prior to but not including such date, and for purposes of
        computations made pursuant to Section 11(a)(iii) hereof, the "current
        market price" per share of the Common Stock or Special Common Stock on
        any date shall be deemed to be the average of the daily closing prices
        per share of such Common Stock or Special Common Stock for the 10
        consecutive Trading Days immediately following but not including such
        date; provided, that if the current market price per share of the Common
        Stock or Special Common Stock is determined during a period following
        the announcement by the issuer of such Common Stock or Special Common
        Stock of (A) a dividend or distribution on such Common Stock or Special
        Common Stock payable in shares of such Common Stock or Special Common
        Stock or securities convertible into shares of such Common Stock or
        Special Common Stock (other than the Rights), or (B) any subdivision,
        combination or reclassification of such Common Stock or Special Common
        Stock, and prior to the expiration of the requisite 30 Trading Day or 10
        Trading Day period, as set forth above, after but not including 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 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
<PAGE>   19

        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 or Special Common Stock are not listed or admitted to
        trading on the New York Stock Exchanges 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 such Common Stock or Special Common Stock are listed or admitted to
        trading or, if the shares of Common Stock or Special 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
        NASDAQ or such other system then in use, or, if on any such date the
        shares of such Common Stock or Special 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 such
        Common Stock or Special 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 or Special Common Stock, the fair value of such
        shares on such date as determined in good faith by the Board of
        Directors of the Company shall be used. The term "Trading Day" shall
        mean a day on which the principal national securities exchange on which
        the shares of Common Stock or Special Common Stock are listed or
        admitted to trading is open for the transaction of business or, if the
        shares of Common Stock or Special Common Stock are not listed or
        admitted to trading on any national securities exchange, a Business Day.
        If the Common Stock or Special Common Stock is not publicly held or not
        so listed or traded, the "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, which determination shall be described in a
        statement filed with the Rights Agent and shall be conclusive for all
        purposes.

               (ii) For the purpose of any computation hereunder, the "current
        market price" per share of Preferred Stock shall be determined in the
        same manner as set forth above for the Common Stock or Special Common
        Stock in clause (i) of this Section 11(d) (other than the last sentence
        thereof). If the current market price per share of Preferred Stock
        cannot be determined in the 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 100 (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. If neither the Common Stock
        nor the Preferred Stock is publicly held or so listed or traded, the
        "current market price" per share of the Preferred Stock shall mean the
        fair value per share as determined in good faith by the Board of
        Directors of the Company, which determination shall be described in a
        statement filed with the Rights Agent and shall be conclusive for all
        purposes. For all purposes of this Agreement, the "current market price"
        of one one-hundredth of a share of Preferred Stock shall be equal to the
        "current market price" of one share of Preferred Stock divided by 100.

               (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,
that any adjustments which by reason of this Section 11(e) are not required to
be made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this Section 11 shall be made to the nearest
cent or to the nearest ten-thousandth of a share of Common Stock or other share
or one-millionth of a share of Preferred Stock, as the case may be.
Notwithstanding the first sentence of this Section 
<PAGE>   20

11(e), any adjustment required by this Section 11 shall be made no later than
the earlier of (i) three years from the date of the transaction which mandates
such adjustment or (ii) the Expiration Date.

               (f) If at any time, as a result of an adjustment made pursuant to
Section 11(a)(ii) or Section 13(a) hereof, the holder of any Right shall be
entitled to receive upon exercise of such Right any shares of capital stock
other than shares of Preferred Stock, thereafter the number of such other shares
so receivable upon exercise of any Right and the Purchase Price thereof shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to the Preferred Stock
contained in Section 11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and
the provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred
Stock shall apply on like terms to any such other shares; provided, however,
that the Company shall not be liable for its inability to reserve and keep
available for issuance upon exercise of the Rights pursuant to Section 11(a)(ii)
a number of shares of its Common Stock and Special Common Stock greater than the
number then authorized by the Company's certificate of incorporation but not
outstanding or reserved for any other purpose.

               (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
share 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-hundredths of a share of Preferred Stock (calculated to the nearest
one-millionth) obtained by (i) multiplying (x) the number of one one-hundredths
of a share covered by a Right immediately prior to this adjustment by (y) the
Purchase Price in effect immediately prior to such adjustment of the Purchase
Price and (ii) dividing the product so obtained by the Purchase Price in effect
immediately after such adjustment of the Purchase Price.

               (i) The Company may elect on or after the date of any adjustment
of the Purchase Price to adjust the number of Rights, in lieu of any adjustment
in the number of one one-hundredths of a share of Preferred Stock purchasable
upon the exercise of a Right. Each of the Rights outstanding after such
adjustment of the number of Rights shall be exercisable for the number of one
one-hundredths of a share of Preferred Stock for which such 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 with prompt notice
thereof to the Rights Agent. This record date may be the date on which the
Purchase Price is adjusted or any day thereafter, but, if the Right Certificates
have been issued, shall be at least 10 days later than the date of the public

<PAGE>   21

announcement. If Right Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Section 11(i), the Company shall, as
promptly as practicable cause to be distributed to holders of record of Right
Certificates on such record date Right Certificates evidencing, subject to
Section 14 hereof, the additional Rights to which such holders shall be entitled
as a result of such adjustment, or, at the option of the Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Right Certificates so to be distributed shall be issued, executed
and countersigned in the manner provided for herein (and 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 Right Certificates on the record date
specified in the public announcement.

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

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

               (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer with prompt notice thereof to
the Rights Agent until the occurrence of such event the issuance to the holder
of any Right exercised after such record date the number of one one-hundredths
of a share of Preferred Stock and other capital stock or securities of the
Company, if any, issuable upon such exercise over and above the number of one
one-hundredths of a share 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, that the
Company shall deliver to such holder a due bill or other appropriate instrument
evidencing such holder's right to receive such additional shares upon the
occurrence of the event requiring such adjustment.

               (m) Anything in this Section 11 to the contrary notwithstanding,
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it in its sole discretion shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Stock, issuance
wholly for cash of any Preferred Stock at less than the current market price,
issuance wholly for cash of Preferred Stock or securities which by their terms
are convertible into or exchangeable for Preferred Stock, stock dividends or
issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Company to the holders of its Preferred Stock, shall not
be taxable to such stockholders.
<PAGE>   22

               (n) The Company covenants and agrees that it shall not at any
time after the Distribution Date (i) consolidate with, (ii) merge with or into,
or (iii) sell or transfer to, in one transaction or a series of related
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 or Persons if (x) at the time of or immediately after such consolidation,
merger or sale there are any rights, warrants or other instruments outstanding
or agreements or arrangements in effect which would substantially diminish or
otherwise eliminate the benefits intended to be afforded by the Rights or (y)
prior to, simultaneously with or immediately after such consolidation, merger or
sale, the stockholders of a Person who constitutes, or would constitute, the
"Principal Party" for the purposes of Section 13(a) hereof shall have received a
distribution of Rights previously owned by such Person or any of its Affiliates
and Associates.

               (o) The Company covenants and agrees that after the Distribution
Date it will not, except as permitted by Section 23, Section 24 or Section 27
hereof, take (or permit any Subsidiary to take) any action if at the time such
action is taken it is reasonably foreseeable that such action will substantially
diminish or otherwise eliminate the benefits intended to be afforded by the
Rights.

               (p) Anything in this Agreement to the contrary notwithstanding,
if the Company shall at any time after the date hereof and prior to the
Distribution Date (i) declare a dividend on the outstanding shares of Common
Stock and Special Common Stock payable in shares of Common Stock or Special
Common Stock, as the case may be, (ii) subdivide the outstanding Common Stock
and Special Common Stock or (iii) combine the outstanding Common Stock and
Special Common Stock into a smaller number of shares, the number of Rights
associated with each share of Common Stock and Special Common Stock, as the case
may be, 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 and Special Common
Stock following any such event shall equal the result obtained by multiplying
the number of Rights associated with each share of Common Stock or Special
Common Stock, as the case may be, immediately prior to such event by a fraction
the numerator of which shall be the total number of shares of Common Stock or
Special Common Stock, as the case may be, outstanding immediately prior to the
occurrence of the event and the denominator of which shall be the total number
of shares of Common Stock or Special Common Stock, as the case may be,
outstanding immediately following the occurrence of such event.

               Section 12. Certificate of Adjusted Purchase Price or Number of
Shares or Redemption Price. Whenever an adjustment is made as provided in
Section 11, Section 13 or Section 23(c) 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, the Common Stock and the
Special Common Stock a copy of such certificate and (c) mail a brief summary
thereof to each holder of a Right Certificate (or, if prior to the Distribution
Date, to each holder of a certificate representing shares of Common Stock or
Special Common Stock) in accordance with Section 25 hereof. Notwithstanding the
foregoing sentence, the failure of the Company to comply therewith shall not
affect the validity of or the force or effect of the requirement for such
adjustment, and any adjustment made pursuant to Section 11, Section 13 or
Section 23(c) shall be 
<PAGE>   23

effective nonetheless. The Rights Agent shall be fully protected in relying on
any such certificate and on any adjustment therein contained and shall have no
duty with respect to 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 (a "Section 13 Event") that following the Stock
Acquisition Date, directly or indirectly, (x) the Company shall consolidate
with, or merge with and into, any other Person, and the Company shall not be the
continuing or surviving corporation of such consolidation or merger, (y) any
Person shall consolidate with, or merge with and into, the Company, and the
Company shall be the continuing or surviving corporation of such consolidation
or merger and, in connection with such consolidation or merger, all or part of
the outstanding shares of Common Stock shall be changed into or exchanged for
stock or other securities of any other Person or cash or any other property, or
(z) the Company shall sell or otherwise transfer (or one or more of its
Subsidiaries shall sell or otherwise transfer), in one transaction or a series
of related 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 or Persons, then, and in each such case, proper
provision shall be made so that (i) each holder of a Right, except as provided
in Section 7(e) hereof, shall thereafter 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 validly authorized and issued, fully paid and
nonassessable shares of freely tradeable Common Stock of the Principal Party (as
hereinafter defined), not subject to any rights of call or first refusal, liens,
encumbrances or other claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the then number of one
one-hundredths of a share of Preferred Stock for which a Right is exercisable
immediately prior to the first occurrence of any Section 13 Event (or, if a
Section 11(a)(ii) Event has occurred prior to the first occurrence of a Section
13 Event, multiplying the number of such 1/100ths of a share for which a Right
was exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event by the Purchase Price in effect immediately prior to such first
occurrence) and dividing that product (which, following the first occurrence of
any Section 13 Event, shall be referred to as the "Purchase Price" for each
Right and for all purposes of this Agreement) by (2) 50% of the current market
price (determined pursuant to Section 11(d)(i) hereof) per share of the Common
Stock of such Principal Party on the date of consummation of such consolidation,
merger, sale or transfer; (ii) the 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 authorization and
reservation of a sufficient number of shares of its Common Stock to permit
exercise of all outstanding Rights in accordance with this Section 13(a)), in
connection with the consummation of any such transaction as may be necessary to
assure that the provisions hereof shall thereafter be applicable, as nearly as
reasonably may be, in relation to the shares of its Common Stock thereafter
deliverable upon the exercise of the Rights.
<PAGE>   24

               (b)    "Principal Party" shall mean

                      (i) in the case of any transaction described in clause (x)
               or (y) of the first sentence of Section 13(a): (A) the Person
               that is the issuer of any securities into which shares of Common
               Stock or Special Common Stock of the Company are converted in
               such merger or consolidation, or, if there is more than one such
               issuer, the issuer the Common Stock of which has the greatest
               market value, or (B) if no securities are so issued, (I) the
               Person that is the other party to such merger or consolidation,
               or, if there is more than one such Person, the Person the Common
               Stock of which has the greatest market value or (II) if the
               Person that is the other party to the merger or consolidation
               does not survive the merger or consolidation, the Person that
               does survive the merger or consolidation (including the Company
               if it survives); and

                      (ii) in the case of any transaction described in clause
               (z) of the first sentence of Section 13(a), the Person that is
               the party receiving the greatest portion of the assets or earning
               power transferred pursuant to such transaction or transactions,
               or, if each Person that is a party to such transaction or
               transactions receives the same portion of the assets or earning
               power so transferred or if the Person receiving the greatest
               portion of the assets or earning power cannot be determined,
               whichever of such Persons as is the issuer of Common Stock having
               the greatest market value of shares outstanding;

provided, that in any such case, (x) 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 of another Person the Common Stock of which is and has been
so registered, "Principal Party" shall refer to such other Person; and (y) in
case such Person is a Subsidiary, directly or indirectly, 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.

               (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 which 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 such Principal
Party 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 or sale or transfer of assets mentioned in paragraph
(a) of this Section 13, the Principal Party will:

               (i) prepare and file a registration statement under the Act with
        respect to the Rights and the securities purchasable upon exercise of
        the Rights on an appropriate form, and will use its best efforts to
        cause such registration statement to (A) become effective as soon as
        practicable after such filing and (B) remain effective (with a
        prospectus at all times meeting the requirements of the Act) until the
        Expiration Date, and similarly comply with applicable state securities
        laws;
<PAGE>   25

               (ii) will deliver to holders of the Rights historical financial
        statements for the Principal Party and each of its Affiliates which
        comply in all respects with the requirements for registration on Form 10
        (or successor form) under the Exchange Act; and

               (iii) use its best efforts to list (and continue the listing of)
        the Rights and the securities purchasable upon exercise of the Rights on
        a national securities exchange or to meet the eligibility requirements
        for quotation on NASDAQ, or other such system then in use.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. If any Section 13 Event shall occur
at any time after the occurrence of a Section 11(a)(ii) Event, the Rights which
have not theretofore been exercised shall thereafter become exercisable in the
manner described in Section 13(a).

               Section 14.  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(p)
hereof, or to distribute Right Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Right Certificates with regard to which such fractional Rights would
otherwise be issuable an amount in cash equal to the same fraction of the
current market value of a whole Right. For the purposes of this Section 14(a),
the current market value of a whole Right shall be the closing price of the
Rights for the Trading Day immediately prior to the date on which such
fractional Rights would have been otherwise issuable. The closing price of the
Rights for any day shall be the last sale price, regular way, or, in case no
such sale takes place on such day, the average of the closing bid and asked
prices, regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the Rights are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the Rights are listed or
admitted to trading or, if the Rights are not listed or admitted to trading on
any national securities exchange, the last quoted price, or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market
as reported by NASDAQ or such other system then in use or, if on any such date
the Rights are not quoted by any such organization, the average of the closing
bid and asked price as furnished by a professional market maker making a market
in the Rights selected by the Board of Directors of the Company. If on any such
date no such market maker is making a market in the Rights the fair value of the
Rights on such date as determined in good faith by the Board of Directors of the
Company shall be used.

               (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are multiples of one
one-hundredth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are multiples of one one-hundredth of a share of
Preferred Stock). In lieu of fractional shares of Preferred Stock that are not
multiples of one one-hundredth of a share of Preferred Stock, the Company may
pay to the registered holders of Right 


<PAGE>   26

Certificates at the time such Right Certificates are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of one one-hundredth of a share of Preferred Stock. For purposes of this
Section 14(b), the current market value of one one-hundredth of a share of
Preferred Stock shall be one one-hundredth 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.

               (c) Following the occurrence of any Triggering Event, the Company
shall not be required to issue fractions of shares of Common Stock or Special
Common Stock, as the case may be, upon exercise of the Rights or to distribute
certificates which evidence fractional shares of Common Stock or Special Common
Stock, as the case may be. In lieu of fractional shares of Common Stock or
Special Common Stock, as the case may be, the Company may pay to the registered
holders of Right Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of one share of Common Stock. For purposes of this Section 14(c), the
current market value of one share of Common Stock shall be the closing price of
one share of the Common Stock (as determined pursuant to Section 11(d)(i)
hereof) for the Trading Day immediately prior to the date of such exercise.

               (d) The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

               Section 15. Rights of Action. All rights of action in respect of
this Agreement, excepting the rights of action given the Rights Agent under this
Agreement, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of
Common Stock and Special Common Stock); and any registered holder of any Right
Certificate (or, prior to the Distribution Date, of the Common Stock or Special
Common Stock), without the consent of the Rights Agent or of the holder of any
other Right Certificate (or, prior to the Distribution Date, of the Common Stock
or Special 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 Right Certificate in the manner provided in such
Right Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and will be entitled to specific performance of the
obligation under, and injunctive relief against actual or threatened violations
of the obligations of, any Person subject to this Agreement.

               Section 16. Agreement of Right Holders. Every holder of a Right
by accepting the same consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

               (a) prior to the Close of Business on the earlier of the
Distribution Date or the Expiration Date, the Rights shall be evidenced by the
certificates for shares of Common Stock and Special Common Stock registered in
the name of the holders of such shares, and the Rights will be transferable only
in connection with the transfer of Common Stock or Special Common Stock, as the
case may be;
<PAGE>   27

               (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the office or offices of the Rights Agent designated for such purposes duly
endorsed or accompanied by a proper instrument of transfer and with the
appropriate forms and certificates fully executed;

               (c) subject to Section 6(a), Section 7(e), and Section 7(f)
hereof, the Company and the Rights Agent may deem and treat the Person in whose
name the Right Certificate (or, prior to the Distribution Date, the associated
Common Stock certificate or Special Common Stock certificate, as the case may
be) is registered as the absolute owner thereof and of the Right evidenced
thereby (notwithstanding any notations of ownership or writing on the Right
Certificate or the associated Common Stock certificate or Special Common Stock
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; and

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

               Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of one
one-hundredths of a share of Preferred Stock or any other securities of the
Company which may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any Right
Certificate be construed to confer upon the holder of any Right Certificate, as
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in Section 25 hereof), or to receive dividends or subscription rights,
or otherwise, until the Right or Rights evidenced by such Right Certificate
shall have been exercised in accordance with the provisions hereof.

               Section 18.  Concerning the Rights Agent.

               (a) The Company agrees to pay the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
disbursements and other disbursements incurred in the administration,
preparation, delivery, amendment 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, damage, judgment, fine, penalty, claim, demand, settlement, cost or
expense, incurred without gross negligence, bad faith 
<PAGE>   28

or willful misconduct on the part of the Rights Agent, for any action taken,
suffered or omitted by the Rights Agent in connection with the acceptance and
administration of this Agreement, including without limitation, the costs and
expenses of defending against any claim of liability. The indemnity provided
herein shall survive the termination of this Agreement and the termination and
the expiration of the Rights. The costs and expenses incurred in enforcing this
right of indemnification shall be paid by the Company. Anything to the contrary
notwithstanding, in no event shall the Rights Agent be liable for special,
punitive, indirect, consequential or incidental loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Rights Agent
has been advised of the likelihood of such loss or damage. Absent gross
negligence, bad faith or wilful misconduct on the part of the Rights Agent, any
liability of the Rights Agent under this Agreement will be limited to the amount
of fees paid by the Company to the Rights Agent.

               (b) The Rights Agent shall be authorized and protected and shall
incur no liability for or in respect of any action taken, suffered or omitted by
it in connection with its administration of this Agreement in reliance upon any
Right Certificate or certificate for Common Stock or certificate for Special
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, or otherwise upon the advice of
counsel as set forth in Section 20.

               Section 19. Merger or Consolidation or Change of Name of Rights
Agent. (a) Any Person 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 a Person succeeding to the shareholder
services 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 an further act on the part of any of the parties hereto,
provided that such Person would be eligible for appointment as a successor
Rights Agent under the provisions of Section 21 hereof. In case at the time such
successor Rights Agent shall succeed to the agency created by this Agreement,
any of the Right Certificates shall have been countersigned but not delivered,
any such successor Rights Agent may adopt the countersignature of a predecessor
Rights Agent and deliver such Right Certificates so countersigned; and in case
at that time any of the Right Certificates shall not have been countersigned,
any successor Rights Agent may countersign such Right Certificates either in the
name of the predecessor Rights Agent or in the name of the successor Rights
Agent; and in all such cases such Right Certificates shall have the full force
provided in the Right Certificates and in this Agreement.

               (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates so countersigned; and in
case at that time any of the Right Certificates shall not have been
countersigned, the Rights Agent may countersign such Right Certificates either
in its prior name or in its changed name; and in all such cases such Right
Certificates shall have the full force provided in the Right Certificates and in
this Agreement.
<PAGE>   29

               Section 20. Duties of Rights Agent. The Rights Agent undertakes
only the duties and obligations expressly imposed by this Agreement upon the
following terms and conditions, by all of which the Company and the holders of
Right Certificates, by their acceptance thereof, shall be bound:

               (a) The Rights Agent may consult with legal counsel (who may be
legal counsel for the Company), and the advice or opinion of such counsel shall
be full and complete authorization and protection to the Rights Agent as to any
action taken, suffered or omitted by it in good faith and in accordance with
such advice or 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"
and the determination of "current market price") be proved or established by the
Company prior to taking, omitting 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, the President or any Vice
President and by the Treasurer or any Assistant Treasurer or the Secretary or
any Assistant Secretary of the Company and delivered to the Rights Agent; and
such certificate shall be full authorization and protection to the Rights Agent
and the Rights Agent shall incur no liabilities for or in respect of any action
taken, omitted 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
gross negligence, bad faith or willful misconduct.

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

               (e) The Rights Agent shall not be under any liability or
responsibility in respect of the validity of this Agreement or the execution and
delivery hereof (except the due execution hereof by the Rights Agent) or in
respect of the validity or execution of any Right Certificate (except its
countersignature thereof); nor shall it be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any Right
Certificate; nor shall it be responsible for any change in the exercisability of
the Rights (including the Rights becoming null and void pursuant to Section 7(e)
hereof) or any adjustment in the terms of the Rights (including the manner,
method or amount thereof) provided for in Sections 3, 11, 13 or 23, and 24 or
the ascertaining of the existence of facts that would require any such
adjustment (except with respect to the exercise of Rights evidenced by Right
Certificates after actual notice of any such adjustment); 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 Common Stock, Special Common Stock
or Preferred Stock to be issued pursuant to this Agreement or any Right
Certificate or as to whether any shares of Common Stock, Special Common Stock or
Preferred Stock will, when issued, be validly authorized and issued, fully paid
and nonassessable.

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

               (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
person reasonably believed by the Rights Agent to be the Chairman of the Board,
the President or any Vice President or the Secretary or any Assistant Secretary
or the Treasurer or any Assistant Treasurer of the Company, and to apply to such
officers for advice or instructions in connection with its duties, and it shall
not be liable for any action taken, suffered or omitted to be taken by it in
good faith in accordance with instructions of any such officer or for any delay
in acting while waiting for those instructions. Any application by the Rights
Agent for written instructions from the Company may, at the option of the Rights
Agent, set forth in writing the action proposed to be taken, suffered or omitted
by the Rights Agent under this Agreement and the date on and/or after which such
action shall be taken or suffered or such omission shall be effective. The
Rights Agent shall not be liable for any action taken or suffered by, or
omission of, the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date shall
not be less than five Business Days after the date any officer of the Company
actually receives such application unless any such officer shall have consented
in writing to an earlier date) unless prior to taking any such action (or the
effective date in the case of an omission), the Rights Agent shall have received
written instructions in response to such application specifying the action to be
taken, suffered or omitted.

               (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though

<PAGE>   31
it were not the 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 Person.

               (i) The Rights Agent may execute and exercise any of the rights
or powers hereby vested in it or perform any duty hereunder either itself or by
or through its attorneys or agents, and the Rights Agent shall not be answerable
or accountable for any act, default, neglect or misconduct of any such attorneys
or agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct, absent gross negligence, bad faith or wilful misconduct
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 Right 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 cases 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 or transfer without first consulting with the Company.

               Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Stock, Special Common Stock and Preferred Stock by
registered or certified mail, and, subsequent to the Distribution Date, to the
holders of the Right Certificates by first-class mail. The Company may remove
the Rights Agent or any successor Rights Agent upon 30 days' notice in writing,
mailed to the Rights Agent or successor Rights Agent, as the case may be, and to
each transfer agent of the Common Stock, Special Common Stock and Preferred
Stock by registered or certified mail, and, subsequent to the Distribution Date,
to the holders of the Right Certificates by first-class mail. If the Rights
Agent shall resign or be removed or shall otherwise become incapable of acting,
the Company shall appoint a successor to the Rights Agent. Notwithstanding the
foregoing provisions of this Section 21, in no event shall the resignation or
removal of a Rights Agent be effective until a successor Rights Agent shall have
been appointed and have accepted such appointment. 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
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Company), then the registered holder of any Right 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, which is authorized to do business under such laws and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50,000,000 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 
<PAGE>   32

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,
Special Common Stock and the Preferred Stock, and, subsequent to the
Distribution Date, mail a notice thereof in writing to the registered holders of
the Right Certificates. Failure to give any notice provided for in this Section
21, however, or any defect therein, shall not affect the legality or validity of
the resignation or removal of the Rights Agent or the appointment of the
successor Rights Agent, as the case may be. Notwithstanding the foregoing
provisions, in the event of resignation, removal or incapacity of the Rights
Agent, the Company shall have the authority to act as the Rights Agent until a
successor Rights Agent shall have assumed the duties of the Rights Agent
hereunder.

               Section 22. Issuance of New Right Certificates. Notwithstanding
any of the provisions of this Agreement or the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares of
stock or other securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Agreement. In addition, in
connection with the issuance or sale of shares of Common Stock or Special Common
Stock following the Distribution Date and prior to the redemption or expiration
of the Rights, the Company (a) shall, with respect to shares of Common Stock or
Special Common Stock, as the case may be, so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, or upon the
exercise, conversion or exchange of securities hereafter issued by the Company,
and (b) may, in any other case, if deemed necessary or appropriate by the Board
of Directors of the Company, issue Right Certificates representing the
appropriate number of Rights in connection with such issuance or sale; provided,
that (i) no such Right Certificate shall be issued if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax consequences to the Company or the
Person to whom such Right Certificate would be issued, and (ii) no such Right
Certificate shall be issued if, and to the extent that, appropriate adjustment
shall otherwise have been made in lieu of the issuance thereof.

               Section 23.  Redemption.

               (a) The Board of Directors of the Company may, at its option, at
any time prior to the earlier of (i) the Close of Business on the tenth day
after the Stock Acquisition Date (or such later date as the Board of Directors
of the Company may determine) or (ii) the Final Expiration Date, elect to redeem
all but not less than all the then outstanding Rights at a redemption price of
$.005 per Right, payable in cash, shares of Common Stock or Special Common Stock
or any other form of consideration deemed appropriate by the Board of Directors
of the Company, subject to the adjustments as provided in subsection (c) below
(such redemption price being hereinafter referred to as the "Redemption Price").
Notwithstanding anything in this Agreement to the contrary, the Rights shall not
be exercisable after the first occurrence of a Section 11(a)(ii) Event until
such time as the Company's right of redemption hereunder has expired.
<PAGE>   33

               (b) Immediately upon the action of the Board of Directors of the
Company electing to redeem 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 for each Right so
held. Promptly after the action of the Board of Directors ordering the
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 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 and the Special Common
Stock. Any notice which is mailed in the manner herein provided shall be deemed
given, whether or not the holder receives the notice. Each such notice of
redemption will state the method by which the payment of the Redemption Price
will be made. Neither the Company nor any of its Affiliates or Associates may
redeem, acquire or purchase for value any Rights at any time in any manner other
than that specifically set forth in this Section 23 or Section 24 hereof, and
other than in connection with the purchase, acquisition or redemption of shares
of Common Stock or Special Common Stock prior to the Distribution Date.

               (c) If the Company shall at any time after the date of this
Agreement (A) pay any dividend on Common Stock in shares of Common Stock, (B)
subdivide or split the outstanding shares of Common Stock into a greater number
of shares or (C) combine or consolidate the outstanding shares of Common Stock
into a smaller number of shares or effect a reverse split of the outstanding
shares of Common Stock, then and in each such event the Redemption Price shall
be adjusted so that the Redemption Price after such event shall equal the
Redemption Price immediately prior to such event multiplied by a fraction the
denominator of which is the number of shares of Common Stock outstanding
immediately after such event and the numerator of which is the number of shares
of Common Stock outstanding immediately prior to such event. In each case,
however, such adjustment to the Redemption Price shall be made only if the
amount of the Redemption Price shall be reduced or increased by $.005 per Right.

               Section 24.  Exchange.

               (a) The Board of Directors of the Company may, at its option, at
any time after any Person, alone or together with its Affiliates and Associates
or otherwise, becomes an Acquiring Person, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become null and void pursuant to the provisions of Section 7(e) hereof) for
shares of Common Stock or Special Common Stock at an exchange ratio of one share
of Common Stock or Special Common Stock per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date hereof (such exchange ratio being hereinafter referred to as the
"Exchange Ratio").

               (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to paragraph (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of the
holders of such Rights shall be to receive that number of shares of Common Stock
or Special Common Stock equal to the number of such Rights held by such holder
multiplied by the Exchange Ratio. The Company shall promptly give public notice
of any such exchange with prompt notice thereof to the Rights Agent; provided,
however, that the failure 
<PAGE>   34

to give, or any defect in, such notice shall not affect the validity of such
exchange. The Company promptly shall mail a notice of any such exchange to all
of the holders of such Rights at their last addresses as they appear upon the
registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the shares of Common Stock or Special Common Stock for Rights will be
effected and, in the event of any partial exchange, the number of Rights which
will be exchanged. Any partial exchange shall be effected pro rata based on the
number of Rights (other than Rights which have become null and void pursuant to
the provisions of Section 7(e) hereof) held by each holder of Rights.

               (c) In any exchange pursuant to this Section 24, the Company, at
its option, may substitute shares of Preferred Stock (or any other series or
preferred stock of the Company containing terms substantially similar to the
terms of the Preferred Stock) for some or all of the shares of Common Stock or
Special Common Stock exchangeable for Rights, at the initial rate of
one-hundredth of a share of Preferred Stock (or of such other series of
preferred stock of the Company) for each share of Common Stock or Special Common
Stock, as appropriately adjusted to reflect any adjustments in the voting rights
of the Preferred Stock pursuant to the terms thereof, so that the fraction of a
share of Preferred Stock (or of such other series of preferred stock of the
Company) delivered in lieu of each share of Common Stock or Special Common Stock
shall have the same voting rights as one share of Common Stock or Special Common
Stock.

               (d) In the event that there shall not be sufficient shares of
Common Stock, Special Common Stock or Preferred Stock (or any other series of
preferred stock of the Company containing terms substantially similar to the
terms of the Preferred Stock) issued but not outstanding or authorized but
unissued to permit any exchange of Rights as contemplated in accordance with
this Section 24, the Company shall take all such action as may be necessary to
authorize additional shares of Common Stock, Special Common Stock or Preferred
Stock (or such other series of preferred stock of the Company) for issuance upon
exchange of the Rights.

               (e) The Company shall not be required to issue fractions of
shares of Common Stock or Special Common Stock or to distribute certificates
which evidence fractional shares of Common Stock or Special Common Stock. In
lieu of such fractional shares, the Company shall pay to the registered holders
of the Right Certificates with regard to which such fractional shares would
otherwise be issuable an amount in cash equal to the same fraction of the
current market value of a whole share of Common Stock or Special Common Stock.
For the purposes of this paragraph (e) the current market value of a whole share
of Common Stock or Special Common Stock shall be the closing price of a share of
Common Stock or Special Common Stock (as closing price is determined pursuant to
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.
<PAGE>   35

               Section 25.  Notice of Proposed Actions.

               (a) In case the Company shall propose, at any time after the
Distribution Date, (i) 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 (ii) to offer to the holders of its
Preferred Stock rights or warrants to subscribe for or to purchase any
additional shares of Preferred Stock or shares of stock of any class or any
other securities, rights or options, or (iii) to effect any reclassification of
its Preferred Stock (other than a reclassification involving only the
subdivision of outstanding shares of Preferred Stock), or (iv) to effect any
consolidation or merger into or with any other Person, 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 transaction or a series of related 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 Persons, or (v) 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 Right Certificate and the Rights
Agent, in accordance with Section 26 hereof, a notice of such proposed action,
which shall specify the record date for the purposes of such stock dividend,
distribution of rights or warrants, or the date on which such reclassification
consolidation, merger, sale, transfer, and liquidation, dissolution, or winding
up is to take place and the date of participation therein by the holders 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 (i) or (ii) above at least 20
days prior to the record date for determining holders of the 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 Preferred Stock, whichever shall be the
earlier. The failure to give notice required by this Section 24 or any defect
therein shall not affect the legality or validity of the action taken by the
Company or the vote upon any such action.

               (b) Notwithstanding anything in this Agreement to the contrary,
prior to the Distribution Date a public filing by the Company with the
Securities and Exchange Commission shall constitute sufficient notice to the
holders of securities of the Company, including the Rights, for purposes of this
Agreement and no other notice need be given.

               (c) In case any Section 11(a)(ii) Event or Section 13 Event shall
occur, then, in any such case, (i) the Company shall as soon as practicable
thereafter give to each holder of a Right Certificate and to the Rights Agent,
in accordance with Section 26 hereof, a notice of the occurrence of such event,
which shall specify the event and the consequences of the event to holders of
Rights under Section 11(a)(ii) or Section 13 hereof and (ii) all references in
the preceding paragraph to Preferred Stock shall be deemed thereafter to refer
to Common Stock, Special Common Stock and, if appropriate, other securities.

               Section 26. Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed (until another address is filed in
writing with the Rights Agent) as follows:

In cases of notice or demands by the Company to the Rights Agent, a fax copy may

Distribution Date, to the holder of any certificate representing shares of
Common Stock or Special Common Stock) shall be sufficiently given or made if
sent by first-class mail, postage prepaid, addressed to such holder at the
address of such holder as shown on the registry books of the Company.

               Section 27. Supplements and Amendments. Prior to the Distribution
Date, the Company may, and the Rights Agent shall, if the Company so directs,
supplement or amend any provision of this Agreement in any respect whatsoever
without the approval of any holders of certificates representing shares of
Common Stock or Special Common Stock, provided that such supplement or amendment
does not change or increase the Rights Agent's duties, liabilities, or
obligations. From and after the Distribution Date, the Company may, and the
Rights Agent shall, if the Company so directs, provided that such supplement or
amendment does not change or increase the Rights Agent's duties, liabilities, or
obligations, supplement or amend this Agreement without the approval of any
holders of Right Certificates in order (i) to cure any ambiguity, (ii) to
correct or supplement any provision contained herein which may be defective or
inconsistent with any other provisions herein, (iii) to shorten or lengthen any
time period hereunder, or (iv) to change or supplement the provisions hereof in
any manner which the Company may deem necessary or desirable and which shall not
adversely affect the interests of the holders of Right Certificates (other than
an Acquiring Person or an Affiliate or Associate of an Acquiring Person);
provided, that this Agreement may not be supplemented or amended to lengthen,
pursuant to clause (iii) of this sentence, (A) a time period relating to when
the Rights may be redeemed at such time as the Rights are not then redeemable or
(B) any other time period unless such lengthening is for the purpose of
protecting, enhancing or clarifying the rights of, and/or the benefits to, the
holders of Rights (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person).
<PAGE>   37

               Upon the delivery of a certificate from an appropriate officer of
the Company which states that the proposed supplement or amendment is in
compliance with the terms of this Section 27, and such supplement or amendment
does not change or increase the Rights Agent's duties, liabilities or
obligations, the Rights Agent shall execute such supplement or amendment. Prior
to the Distribution Date, the interests of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Stock or Special Common
Stock, as the case may be.

               Section 28.  Successors.  All the covenants and provisions of
this Agreement by or for the benefit of the Company or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

               Section 29. Determinations and Actions by the Board of Directors,
etc. For all purposes of this Agreement, any calculation of the number of shares
of Common Stock or Special Common Stock outstanding at any particular time,
including for purposes of determining the particular percentage of such
outstanding shares of Common Stock or Special Common Stock of which any Person
is the Beneficial Owner, shall be made in accordance with the last sentence of
Rule l3d-3(d)(l)(i) of the General Rules and Regulations under the Exchange Act.
The Board of Directors of the Company shall have the exclusive power and
authority to administer this Agreement and to exercise all rights and powers
specifically granted to the Board or to the Company, or as may be necessary or
advisable in the administration of this Agreement, including, 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) which 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 and all other parties, and (y) not
subject the Board of Directors of the Company to any liability to the holders of
the Right.

               Section 30. Benefits of this Agreement. Nothing in this Agreement
shall be construed to give to any Person other than the Company, the Rights
Agent and the registered holders of the Right Certificates (and, prior to the
Distribution Date, the Common Stock and Special Common Stock) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Right Certificates (and, prior to the Distribution
Date, the Common Stock and Special 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
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

               Section 32. Governing Law. This Agreement, each Right and each
Right Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of 
<PAGE>   38

such State applicable to contracts to be made and performed entirely within such
State; provided, however, that all provisions regarding the rights, duties and
obligations of the Rights Agent shall be governed by and construed in accordance
with the laws of the State of New York applicable to contracts made and to be
performed entirely within such State.

               Section 33. Counterparts. This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and all such counterparts shall together constitute
one and the same instrument.

               Section 34. Descriptive Headings. The captions herein and table
of contents hereto are included for convenience of reference only, do not
constitute a part of this Agreement and shall be ignored in the construction and

                           CERTIFICATE OF DESIGNATION
                                       OF
                             SERIES A PARTICIPATING
                           CUMULATIVE PREFERRED STOCK
                                       OF
                       KAUFMAN AND BROAD HOME CORPORATION



                         Pursuant to Section 151 of the
                         General Corporation Law of the
                                State of Delaware


               We, Bruce Karatz, President, and Alan R. Markizon, Secretary, of
Kaufman and Broad Home Corporation (the "Corporation"), organized and existing
under the General Corporation Law of the State of Delaware, in accordance with
the provisions of Section 103 thereof, DO HEREBY CERTIFY:

               FIRST: Pursuant to the authority conferred upon the Board of
Directors by Article FOURTH of the Amended Certificate of Incorporation of the
Corporation, the Board of Directors at a meeting held on January 11, 1989
adopted resolutions authorizing the creation of a series of up to 1,600,000
shares of Preferred Stock designated as Series A Participating Cumulative
Preferred Stock with such voting, dividend, liquidation and other rights,
preferences and terms and limitations substantially as set forth below, subject
to such changes as a committee (the "Committee"), composed of the Chairman of
the Board of Directors and the President of the Corporation, to the extent
permitted by Delaware law, deem appropriate and in the interests of the
Corporation.

               SECOND:  The following resolutions were adopted by the Committee 
on February 28, 1989, and are in full force and effect on the date hereof:

               RESOLVED, that pursuant to the authority vested in the Board of
Directors of this Corporation and in this Committee in accordance with the
provisions of its Certificate of Incorporation and Bylaws, a series of Preferred
Stock of the Corporation be and it hereby is created, and that the designation
and amount thereof and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such series,
and the qualifications, limitations or restrictions thereof are as follows:

               Section 1. Designation and Amount. There shall be a series of
Preferred Stock designated as "Series A Participating Cumulative Preferred
Stock" (the "Rights Preferred Stock") and the initial number of shares
constituting such series shall be 1,600,000.
<PAGE>   41

               Section 2. Rank. The Rights Preferred Stock shall, with respect
to dividend rights and rights on liquidation, winding up and dissolution, rank
prior to all classes of common stock of the Corporation. The Rights Preferred
Stock shall rank junior with respect to payment of dividends and on liquidation
to all other series of the Corporation's Preferred Stock outstanding on the date
hereof and to all such other series that specifically provide that they shall
rank senior to the Rights Preferred Stock. Each share of the Rights Preferred
Stock shall rank equally in all respects. All equity securities of the
Corporation to which the Rights Preferred Stock ranks or shall rank prior
(whether with respect to dividends or upon liquidation, dissolution, winding up
or otherwise), including the Common Stock, $1.00 par value per share (the
"Common Stock"), and the Special Common Stock, $1.00 par value per share, of the
Corporation are collectively referred to herein as the "Junior Securities". All
equity securities of the Corporation with which the Rights Preferred Stock ranks
or shall rank on a parity (whether with respect to dividends or upon
liquidation, dissolution, winding up or otherwise) are collectively referred to
herein as the "Parity Securities". All equity securities of the Corporation to
which the Rights Preferred Stock ranks or shall rank junior (whether with
respect to dividends or upon liquidation, dissolution, winding up or otherwise)
are collectively referred to herein as the "Senior Securities".

               Section 3.  Dividends and Distributions.

               (A) Subject to the prior and superior rights of the holders of
any Senior Securities, the holders of shares of Rights Preferred Stock, in
preference to the shares of Common Stock and any other Junior Securities shall
be entitled to receive, when, as and if declared by the Board of Directors, out
of funds at the time legally available for payment of dividends, quarterly
dividends payable in cash on March 31, June 30, September 30 and December 31
(each, a "Quarterly Dividend Payment Date") in each year (unless any such day is
not a business day, in which event on the next succeeding business day),
commencing on the first Quarterly Dividend Payment Date after the first issuance
of a share or fraction of a share of Rights Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $1.00 or, (b)
subject to the provision for adjustment hereinafter set forth, 100 times the
aggregate per share amount of all cash dividends and 100 times the aggregate per
share amount (payable in kind) of all non-cash dividends or other distributions
other than a dividend payable in shares of Common Stock or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise), declared
on the Common Stock, since the immediately preceding Quarterly Dividend Payment
Date, or, with respect to the first Quarterly Dividend Payment Date, since the
first issuance of any share or fraction of a share of Rights Preferred Stock. If
the Corporation shall at any time after March 5, 1999 (the "Rights Declaration
Date") (i) declare any dividend on Common Stock payable in shares of Common
Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount to which holders of shares of Rights Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

               (B) The Corporation shall declare a dividend or distribution on
the Rights Preferred Stock as provided in paragraph (A) above immediately after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided that, if no dividend or
distribution shall have been declared on the Common Stock 
<PAGE>   42

during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Rights Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

               (C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Rights Preferred Stock from the Quarterly Dividend Payment
Date next preceding the date of issue of such shares of Rights Preferred Stock,
unless the date of issue of such shares is prior to the record date for the
first Quarterly Dividend Payment Date, in which case dividends on such shares
shall begin to accrue and be cumulative from the data of issue of such shares,
or unless the date of issue is a Quarterly Dividend Payment Date or is a date
after the record date for the determination of holders of shares of Rights
Preferred Stock entitled to receive a quarterly dividend and before such
Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Dividends in arrears may be declared and paid at any time without reference to
any regular Quarterly Dividend Payment Date. Each dividend shall be paid to the
holders of record of shares of the Rights Preferred Stock as they appear on the
stock books of the Corporation on such date, not more than 60 nor less than 10
days preceding the payment date thereof, as may be fixed by the Board of
Directors or a duly authorized committee thereof.

               (D) The Corporation shall not declare, pay or set apart for
payment any dividend on any Junior Securities or make any distribution in
respect thereof, either directly or indirectly, in cash, obligations or shares
of the Corporation or other property (all such dividends and distributions being
hereinafter referred to as "Junior Securities Distributions") unless all accrued
and unpaid cumulative dividends or other dividends or distributions have been
paid or declared and set apart for payment on or in respect of the Rights
Preferred Stock through the then most recent Quarterly Dividend Payment Date. As
long as any dividend on the Rights Preferred Stock is in arrears, the
Corporation shall not, and shall not permit any corporation or other entity
directly or indirectly controlled by the Corporation to, redeem, purchase or
otherwise acquire for value any Junior Securities or make any payment on account
of or set apart for payment money for a sinking or other similar fund for the
purchase, redemption or other retirement of, any Junior Securities.
Notwithstanding the foregoing, this Section 3(D) shall not prohibit the payment
or declaration and setting aside of a dividend payable solely in shares of
Junior Securities or a redemption, purchase or acquisition of Junior Securities
solely with shares of Junior Securities.

               (E) The corporation shall not declare, pay or set apart for
payment by the Corporation any full dividend on any Parity Securities for any
period unless and until all accrued and unpaid cumulative dividends have been or
contemporaneously are declared and paid or declared and a sum set apart
sufficient for such payment on the Rights Preferred Stock through the then most
recent Quarterly Dividend Payment Date. If any dividend is not paid in full upon
the shares of the Rights Preferred Stock, the Corporation shall not declare, pay
or set apart for payment any dividend on any Parity Securities or make any
distribution in respect thereof, either directly or indirectly, in cash,
obligations or shares of the Corporation or other property (all such dividends
and distributions being hereinafter referred to as "Parity Securities
Distributions") unless dividends and distributions are declared and paid on the
Exchangeable Preferred Stock pro rata with any Parity Securities Distribution
declared and paid on any Parity Securities so that the amount of dividends and
distributions declared and paid per share of the Rights Preferred Stock and such
Parity Securities shall in all cases bear to each other the same ratio that
accrued 
<PAGE>   43

dividends per share on the Rights Preferred Stock and the Parity Securities bear
to each other. Any dividend or distribution paid on the shares of Rights
Preferred Stock shall be allocated pro rata on a share-by-share basis among all
such shares at the time outstanding.

               (F) Except as otherwise provided in Section 4(D), as long as any
dividend on the Rights Preferred Stock is in arrears, the Corporation shall not,
and shall not permit any corporation or other entity directly or indirectly
controlled by the Corporation to, redeem, purchase or otherwise acquire for
value any Rights Preferred Stock or Parity Securities or make any payment on
account of or set apart for payment money for a sinking or other similar fund
for the purchase, redemption or other retirement of, any Rights Preferred Stock
or Parity Securities.

               (G) No interest, or sum of money in lieu of interest, shall be
payable in respect of any dividend payment or any other payment in respect of
the Rights Preferred Stock or any Parity Securities which may be in arrears.

               Section 4.  No Redemption.  The shares of Rights Preferred Stock
shall not be redeemable.

               Section 5.  Liquidation or Dissolution.

               (A) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of Rights Preferred
Stock then outstanding shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth and subject
to any greater amount as may be provided in Section 5(B) hereof, equal to 100
times the aggregate amount to be distributed per share to holders of Common
Stock. If the Corporation shall at any time after the Rights Declaration Date
declare or pay any dividend on Common Stock payable in shares of Common Stock,
or effect a subdivision or combination or consolidation of the outstanding
shares of Common Stock (by reclassification or otherwise than by payment of a
dividend in shares of Common Stock) into a greater or lesser number of shares of
Common Stock, then in each such case the aggregate amount to which holders of
shares of Rights Preferred Stock were entitled immediately prior to such event
under the preceding sentence shall be adjusted by multiplying such amount by a
fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event. After the payment to the holders of shares of the Rights Preferred Stock
of the full preferential amounts provided for in this Section 5(A) and in
Section 5(B), the holders of the Rights Preferred Stock as such shall have no
right or claim to any of the remaining assets of the Corporation.

               (B) Before any payment shall be made to the holders of any Junior
Securities, in the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of Rights Preferred
Stock then outstanding shall be entitled to be paid out of the assets of the
Corporation available for distribution to its stockholders, an amount equal to
$100.00 per share (plus an amount equal to unpaid cumulative dividends thereon
accrued to the date of liquidation, dissolution or winding up, whether or not
declared and whether or not such date is a regular quarterly dividend payment
date), without interest.
<PAGE>   44

               (C) A merger or consolidation of the Corporation with or into any
other corporation or a voluntary sale, exchange, transfer or conveyance of all
or any part of the assets of the Corporation (which shall not in fact result in
the liquidation of the Corporation and the distribution of assets to
stockholders) shall not be deemed to be a voluntary or involuntary liquidation
or dissolution or winding up of the Corporation within the meaning of this
Section 5.

               (D) If the assets of the Corporation available for distribution
to the holders of shares of the Rights Preferred Stock upon any dissolution,
liquidation or winding up of the Corporation, whether voluntary or involuntary,
shall be insufficient to pay in full all amounts to which such holder are
entitled pursuant to Sections 5(A) and 5(B) above, no such distribution shall be
made on account of any Parity Securities upon such dissolution, liquidation or
winding up unless amounts shall be paid on account of the shares of Rights
Preferred Stock pro rata in proportion to the full amounts to which holders of
all the Rights Preferred Stock and such Parity Securities are respectively
entitled upon such dissolution, liquidation or winding up.

                Section 6. No Sinking Fund. The shares of Rights Preferred Stock
shall not be subject to the operation of a purchase, retirement or sinking fund.

                Section 7. Voting Rights. In addition to any other voting rights
required by law, the holders of shares of Rights Preferred Stock shall have the
following voting rights:

               (A) Subject to the provision for adjustment set forth in this
Section 7(A), holders of Rights Preferred Stock shall be entitled to 100 votes
per share with respect to all matters submitted to a vote of the holders of the
Common Stock as well as with any other class or series of stock of the
Corporation then having the right to vote with the Common Stock concerning any
matter being voted upon by holders of the Common Stock. If the Corporation shall
at any time after the Rights Declaration Date (i) declare any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the number of votes per share to which holders of
shares of Rights Preferred Stock were entitled immediately prior to such event
shall be adjusted by multiplying such number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

               Holders of shares of Rights Preferred Stock, holders of shares of
Common Stock and holders of shares of such other series or class of stock shall
vote together as one class except as provided in this Section 7 and the
Certificate of Incorporation of the Corporation and as provided by law. Shares
of the Rights Preferred Stock shall at no time be entitled, as a series,, class
or otherwise, to cumulate their votes in the election of directors or be
entitled to any additional, other or special or restrictive voting rights of any
kind whatsoever, except as provided in this Section 7 and as provided by law.

               (B) If at any time cumulative dividends on the outstanding shares
of Rights Preferred Stock shall be accrued and unpaid in an aggregate amount per
share equal to or exceeding six quarterly dividends thereon, then the number of
directors constituting the Board of Directors without further action shall be
increased by two, and the holders of shares of Rights 

<PAGE>   45

Preferred Stock voting separately as a class together with holders of all other
shares of Preferred Stock of the Corporation that are either Senior Securities
or Parity Securities and that have substantially similar voting rights with
respect to the election of directors which have fully vested by the terms of
such stock as a result of the occurrence of substantially similar or greater
arrearages of dividends (such other series of Preferred Stock being herein
referred to as "Other Voting Preferred Stock"), shall thereupon have the right
(exercisable only at the time, in the manner and subject to the conditions and
during the period hereinafter stated) to elect two members of the Board of
Directors, the remaining directors to be elected by the class or classes of
stock entitled to vote therefor, including the Rights Preferred Stock, at each
meeting of stockholders held for the purpose of electing directors. Each share
of Rights Preferred Stock and Other Voting Preferred Stock shall have one vote
per share with respect to the election of directors pursuant to this Section
7(B).

               (C) Whenever the voting right described in Section 7(B) shall
have vested, such right may be exercised initially either at a special meeting
of the holders of Rights Preferred Stock and Other Voting Preferred Stock,
called as hereinafter provided, or at any annual meeting of stockholders hold
for the purpose of electing directors, and thereafter at such annual meetings.
Such voting right shall continue until such time as all accrued dividends on the
Rights Preferred Stock shall have been paid in full at which time such voting
right of the holders of Rights Preferred Stock shall terminate, subject to
revesting in the event of each and every subsequent failure of the Corporation
of the character described in Section 7(B).

               (D) At any time when the voting right described in Section 7(B)
shall have vested in the holders of Rights Preferred Stock and if such right
shall not already have been exercised in full by Other Voting Preferred Stock, a
proper officer of the Corporation shall, upon the written request of any holder
of record of Rights Preferred Stock then outstanding, addressed to the Secretary
of the Corporation, call a special meeting of holders of Rights Preferred Stock
and holders of Other Voting Preferred Stock. Such meeting shall be held at the
earliest practicable date upon the notice required for annual meetings of
stockholders at the place for holding annual meetings of stockholders of the
Corporation or, if none, at a place designated by the Secretary of the
Corporation. If such meeting shall not be called by the proper officer of the
Corporation within 30 days after the personal service of such written request
upon the Secretary of the Corporation, or within 30 days after mailing the same
within the United States, by registered mail, addressed to the Secretary of the
Corporation at its principal office (such mailing to be evidenced by the
registry receipt issued by the postal authorities), then the holders of record
of 10% of the shares of Rights Preferred Stock then outstanding may designate in
writing any holder of such stock to call such meeting at the expense of the
Corporation, and such meeting may be called by such person so designated upon
the notice required for annual meetings of stockholders and shall be held at the
same place as is elsewhere provided in this Section 7(D). Any holder of Rights
Preferred Stock which would be entitled to vote at such meeting shall have
access to the stock books of the Corporation for the purpose of causing a
meeting of holders of shares of Rights Preferred Stock and Other Voting
Preferred Stock to be called pursuant to the provisions of this Section 7 (D).
Notwithstanding the provisions of this Section 7(D), however, no such special
meeting shall be called during a period within 90 days immediately preceding the
date fixed for the next annual meeting of stockholders. Holders of Rights
Preferred Stock shall be entitled to receive notice of, participate in and vote
at any meeting of holders of Other Voting 

<PAGE>   46

Preferred Stock with respect to the election of directors to the same extent as
provided in Sections 7(B) through 7(G).

               (E) At any meeting held for the purpose of electing directors at
which the holders of Rights Preferred Stock shall have the right, voting
together as a class with holders of shares of Other Voting Preferred Stock, to
elect directors as provided in Section 7(B), the presence in person or by proxy
of the holders of at least 10% of the then outstanding aggregate number of
shares of Rights Preferred Stock and Other Voting Preferred Stock shall be
required and be sufficient to constitute a quorum of such class for the election
of directors by such class. At any such meeting or adjournment thereof (i) the
absence of a quorum of the holders of' shares of Rights Preferred Stock and
Other Voting Preferred Stock shall not prevent the election of directors other
than those to be elected by the holders of stock of such class and the absence
of a quorum or quorums of the holders of capital stock entitled to elect such
other directors shall not prevent the election of directors to be elected by the
holders of shares of Rights Preferred Stock and, if applicable, Other Voting
Preferred Stock and (ii) in the absence of a quorum of the holders of any class
of stock entitled to vote for the election of directors, a majority of the
holders present in person or by proxy of such class shall have the power to
adjourn the meeting for the election of directors which the holders of such
class are entitled to elect, from time to time, without notice (except as
required by law) other than announcement at the meeting, until a quorum shall be
present.

               (F) The term of office of all directors elected by the holders of
shares of Rights Preferred Stock and Other Voting Preferred Stock pursuant to
Section 7(B) or such substantially similar provisions of Other Voting Preferred
Stock who are in office at any time when the voting right described in Section
7(B) is vested in the holders of Rights Preferred Stock shall terminate upon the
election of their successors at any meeting of holders of Rights Preferred Stock
and, if applicable, Other Voting Preferred Stock for the purpose of electing
directors. Except to the extent otherwise provided by the terms of the Other
Voting Preferred Stock, upon any termination of such voting rights in accordance
with Section 7(C), the term of office of all directors elected pursuant to
Section 7(B) then in office shall thereupon terminate and upon such termination
the number of directors constituting the Board of Directors shall, without
further action, be reduced by two, subject always to the increase of the number
of directors pursuant to Section 7(B) in case of the future right of the holders
of Rights Preferred Stock to elect directors as provided therein.

               (G) In case of any vacancy occurring among the directors elected
pursuant to Section 7(B), the remaining director who shall have been so elected
may appoint a successor to hold office for the unexpired term of the director
whose place shall be vacant. If both directors so elected shall cease to serve
as directors before their terms shall expire, the holders of shares of Rights
Preferred Stock and shares of any Other Voting Preferred Stock then outstanding
may, at a special meeting of the holders called as provided above, elect
successors to hold office for the unexpired terms of such directors whose places
shall be vacant.

               Section 8. Consolidation, Merger, etc. In case the Corporation
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other stock
or securities, cash and/or any other property, then in any such case the shares
of Rights Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment 
hereinafter 

<PAGE>   47

set forth) equal to 100 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is changed or exchanged. If the Corporation
shall at any time after the Rights Declaration Date (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
Common Stock, or (iii) combine the outstanding Common Stock into a smaller
number of shares, then in each such case the amount set forth in the preceding
sentence with respect to the exchange or change of shares of Rights Preferred
Stock shall be adjusted by multiplying such amount by a fraction the numerator
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.

               Section 9. Reacquired Shares. Shares of Rights Preferred Stock
which have been issued and reacquired in any manner, including shares purchased,
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation and upon compliance with any applicable
provisions of the laws of the State of Delaware have the status of authorized
and unissued shares of Preferred Stock of the Corporation undesignated as to
series and may be redesignated and reissued as part of any series of Preferred
Stock.

               Section 10. Notice of Certain Actions. If the Corporation
consolidates or merges with, or transfers all or substantially all of its assets
to, another corporation, and stockholders of the Corporation must approve the
transaction or there is a dissolution or liquidation of the Corporation, then
the corporation shall mail to holders of the Rights Preferred Stock a notice
stating the proposed record date or, in the case of transactions for which no
record date need be determined, the effective date. The Corporation shall mail
the notice at least 10 days before such date. Failure to mail the notice or any
defect in such notice shall not affect the validity of any transaction referred
to in this Section 10.

               Section 11. No Implied Limitations. Except as otherwise provided
by express provisions of this Certificate of Designation, nothing herein shall
limit, by inference or otherwise, the discretionary right of the Board of
Directors to classify and reclassify and issue any shares of Preferred Stock and
to fix or alter all terms thereof to the full extent provided in the Certificate
of Incorporation of the Corporation.

               Section 12. General Certificate of Incorporation Provisions. In
addition to the above provisions with respect to the Rights Preferred Stock,
such Rights Preferred Stock shall be subject to, and shall be entitled to the
benefits of, the provisions set forth in the Corporation's Certificate of
Incorporation.

               Section 13. Amendments. So long as any shares of the Rights
Preferred Stock are outstanding, the Corporation shall not without the written
consent or the affirmative vote of holders of at least a majority of the Rights
Preferred Stock at the time outstanding amend or change any terms of the Rights
Preferred Stock or other provisions of the Certificate of Incorporation (by
merger or otherwise) so as to affect materially and adversely the Rights
Preferred Stock.

               Section 14. Fractional Shares. Rights Preferred Stock may be
issued in fractions of a share which shall entitle the holder, in proportion to
such holder's fractional shares, to 

<PAGE>   48

exercise voting rights, receive dividends, participate in distributions and to
have the benefit of all other rights of holders of Rights Preferred Stock.

               IN WITNESS WHEREOF, the Corporation has caused this Certificate
of Designation to be signed in its name and on its behalf on this ___ day of
_____________ by an officer of the Corporation who acknowledges that this
Certificate of Designation is the act of the Corporation and that to the best of
his knowledge, information and belief and under penalties for perjury, all
matters and facts contained in this Certificate of Designation with respect to
authorization and approval thereof are true in all material respects.

share (the "Purchase Price"), upon presentation and surrender of this Right
Certificate with the Form of Election to Purchase and the related Certificate
duly executed. The number of Rights evidenced by this Right Certificate (and the
number of shares which may be purchased upon exercise thereof) set forth above,
and the Purchase Price per share set forth above, are the number and Purchase
Price as of March 5, 1999 based on the Preferred Stock as constituted at such
date.

               Upon the occurrence of a Section 11(a)(ii) Event (as such term is
defined in the Rights Agreement), if the Rights evidenced by this Right
Certificate are beneficially owned by (i) an Acquiring Person or an Affiliate or
Associate of any such Acquiring Person (as such terms are defined in the Rights
Agreement), (ii) a transferee of any such Acquiring Person, Associate or
Affiliate, or (iii) under certain circumstances specified in the Rights

Acquiring Person, or an Affiliate or Associate of an Acquiring Person, such
Rights shall become null and void and no holder hereof shall have any right with
respect to such Rights from and after the occurrence of such Section 11(a)(ii)
Event.

               As provided in the Rights Agreement, the Purchase Price and the
number and kind of shares of Preferred Stock or other securities which may be
purchased upon the exercise of the Rights evidenced by this Right Certificate
are subject to modification and adjustment upon the happening of certain events.

               This Right Certificate is subject to all of the terms, provisions
and conditions of the Rights Agreement, which terms, provisions and conditions
are hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Right Certificates, which
limitations of rights include the temporary suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the above-mentioned office of the
Rights Agent and are also available upon written request to the Rights Agent.

               This Right Certificate, with or without other Right Certificates,
upon surrender at the office or offices of the Rights Agent designated for such
purpose, may be exchanged for another Right Certificate or Right Certificates of
like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of one one-hundredths of a share of Preferred Stock as the
Rights evidenced by the Right Certificate or Right Certificates surrendered
shall have entitled such holder to purchase. If this Right Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender hereof
another Right Certificate or Right Certificates for the number of whole Rights
not exercised.

               Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Board of Directors at a
redemption price of $.005 per Right at any time prior to the Close of Business
on the tenth day after the Stock Acquisition Date, as such term is defined in
the Rights Agreement (or such later date as the Board of Directors of the
Company may determine). Subject to the provisions of the Rights Agreement, the
rights evidenced by this Right Certificate may be exchanged in whole or part for
shares of Common Stock or Special Common Stock or fractional shares of Preferred
Stock (or any other substantially similar series of preferred stock).

<PAGE>   51

               No fractional shares of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a share of Preferred Stock, which
may, at the election of the Company, be evidenced by depositary receipts), but
in lieu thereof a cash payment will be made, as provided in the Rights
Agreement.

               Any of the provisions of the Rights Agreement may be amended by
the Board of Directors of the Company in any respect whatsoever up until the
Distribution Date and thereafter in certain respects which do not adversely
affect the interests of holders of Rights Certificates (other than an Acquiring
Person or the Affiliates or Associates thereof) and which does not increase the
Rights Agent's duties, liabilities or obligations.

               No holder of this Right Certificate shall be entitled to vote or
receive dividends or be deemed for any purpose the holder of shares of Preferred
Stock or of any other securities of the Company which may at any time be
issuable on the exercise hereof, nor shall anything contained in the Rights
Agreement or herein be construed to confer upon the holder hereof, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or, to
receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this Right
Certificate shall have been exercised as provided in the Rights Agreement.

               This Right Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.
