Item 5. Other Events.

     On October 1, 1998, the Board of Directors of Engelhard Corporation (the
"Company") declared a dividend distribution of one Right for each outstanding
share of Common Stock, $1.00 par value (the "Common Stock"), of the Company. The
distribution is payable to holders of record on November 13, 1998 (the "Record
Date"). Each Right entitles the registered holder to purchase from the Company
one one-thousandth of a share of Series A Junior Participating Preferred Stock
(the "Preferred Stock"), at a price of $100 per one one-thousandth of a share
(the "Purchase Price"), subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") between the
Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the
"Rights Agent").

Distribution Date; Transfer of Rights

     Until the earlier to occur of (i) ten calendar days following the date (the
"Shares Acquisition Date") of public announcement that a person or group of
affiliated or associated persons, subject to certain exceptions (an "Acquiring
Person") acquired, or obtained the right to acquire, beneficial ownership of
Common Stock or other voting securities ("Voting Stock") that have 15% or more
of the voting power of the outstanding shares of Voting Stock or (ii) ten
calendar days (or such later date as may be determined by action of the Board of
Directors prior to the time any person or group of affiliated persons becomes an
Acquiring Person) following the commencement or announcement of an intention to
make a tender offer or exchange offer the consummation of which would result in
such person or group acquiring, or obtaining the right to acquire, beneficial
ownership of Voting Stock having 15% or more of the voting power of the
outstanding shares of Voting Stock (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced, with respect to any of the
Company's Common Stock certificates outstanding as of the Record Date, by such
Common Stock certificates. The Rights Agreement provides that, until the
Distribution Date, the Rights will be transferred with and only with the
Company's Common Stock. Until the Distribution Date (or earlier redemption or
expiration of the Rights), new Common Stock certificates issued after the Record
Date upon transfer or new issuance of the Company's Common Stock will contain a
notation incorporating the Rights Agreement by reference. Until the Distribution
Date (or earlier redemption or expiration of the Rights), the surrender for
transfer of any of the Company's Common Stock certificates outstanding as of the
Record Date will also constitute the transfer of the Rights associated with the
Common 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 Company's Common Stock
as of the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights. The Rights Agreement provides that,
as defined therein, the term "Acquiring Person" shall not include any the
Minorco Entities or the 


                                       2
<PAGE>

Minorco Designee as long as they are the Beneficial Owner of less than the
Grandfathered Percentage.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire at the close of business on October 1, 2008, unless earlier redeemed or
exchanged by the Company as described below.

Exercise of Rights for Common Stock of the Company

     In the event that a Person becomes an Acquiring Person, each holder of a
Right will thereafter have the right to receive, upon exercise, Common Stock
(or, in certain circumstances, cash, property or other securities of the
Company) having a value equal to two times the Purchase Price of the Right.
Notwithstanding any of the foregoing, following the occurrence of the event set
forth in this paragraph, all Rights that are, or (under certain circumstances
specified in the Rights Agreement) were, beneficially owned by any Acquiring
Person will be null and void.

Exercise of Rights for Shares of the Acquiring Company

     In the event that, at any time following the Shares Acquisition Date, (i)
the Company is acquired in a merger or other business combination transaction,
or (ii) 50% or more of the Company's assets or earning power is sold or
transferred, each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, common stock of the acquiring company having a value equal to two
times the Purchase Price of the Right.

Adjustments to Purchase Price

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

     With certain exceptions, no adjustment in the Purchase Price will be
required until the earlier of (i) three years from the date of the event giving
rise to such adjustment and (ii) the time at which cumulative adjustments
require an adjustment of at least 1% in such Purchase Price. No fractional
shares will be issued (other than fractional shares which are integral multiples
of one one-thousandth of a share of Preferred Stock) and, in lieu 

                                       3
<PAGE>

thereof, an adjustment in cash will be made based on the market price of the
Preferred Stock on the last trading date prior to the date of exercise.

Redemption and Exchange of Rights

     At any time after the occurrence of the event set forth under the heading
"Exercise of Rights for Common Stock of the Company" above, the Board of
Directors (with the concurrence of a majority of the Independent Directors (as
defined below)) may exchange the Rights (other than Rights owned by the
Acquiring Person which shall have become void), in whole or in part, at an
exchange ratio of one share of Common Stock (or a fraction of a share of
Preferred Stock having the same market value) per Right (subject to adjustment).

     At any time prior to 5:00 P.M. New York City time on the tenth calendar day
following the Shares Acquisition Date, the Company may redeem the Rights in
whole, but not in part, at a price of $.001 per Right (the "Redemption Price").
Under certain circumstances set forth in the Rights Agreement, the decision to
redeem shall require that there be Independent Directors in office and that a
majority of the Independent Directors concur in such decision. Immediately upon
the action of the Board of Directors of the Company electing to redeem the
Rights with, if required, the concurrence of the Independent Directors, the
Company shall make announcement thereof, and upon such action, the right to
exercise the Rights will terminate and the only right of the holders of Rights
will be to receive the Redemption Price.

     Until a Right is exercised or exchanged, 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.

Terms of the Preferred Stock

     The Preferred Stock will rank junior to all other series of the Company's
preferred stock with respect to payment of dividends and as to distributions of
assets in liquidation. Each share of Preferred Stock will have a quarterly
dividend rate per share equal to the greater of $1.00 or 1000 times the per
share amount of any dividend (other than a dividend payable in shares of Common
Stock or a subdivision of the Common Stock) declared from time to time on the
Common Stock, subject to certain adjustments. The Preferred Stock will not be
redeemable. In the event of liquidation, the holders of the Preferred Stock will
be entitled to receive a preferred liquidation payment per share of $1.00 (plus
accrued and unpaid dividends) or, if greater, an amount equal to 1000 times the
payment to be made per share of Common Stock, subject to certain adjustments.
Generally, each share of Preferred Stock will vote together with the Common
Stock and any other series of cumulative preferred stock entitled to vote in
such manner and will be entitled to 1000 votes, subject to certain adjustments.
In the event of any merger, 

                                       4
<PAGE>

consolidation, combination or other transaction in which shares of Common Stock
are exchanged for or changed into other stock or securities, cash and/or other
property, each share of Preferred Stock will be entitled to receive 1000 times
the aggregate amount of stock, securities, cash and/or other property, into
which or for which each share of Common Stock is changed or exchanged, subject
to certain adjustments. The foregoing dividend, voting and liquidation rights of
the Preferred Stock are protected against dilution in the event that additional
shares of Common Stock are issued pursuant to a stock split or stock dividend or
distribution. Because of the nature of the Preferred Stock's dividend, voting,
liquidation and other rights, the value of the one one-thousandth of a share of
Preferred Stock purchasable with each Right is intended to approximate the value
of one share of Common Stock.

Amendments to Terms of the Rights

     Any of the provisions of the Rights Agreement may be amended by the Board
of Directors of the Company prior to the earlier of the Distribution Date and
the Shares Acquisition Date. After the earlier of the Distribution Date and the
Shares Acquisition Date, the provisions of the Rights Agreement may be amended
by the Board (in certain circumstances, with the concurrence of the Independent
Directors) in order to cure any ambiguity, defect or inconsistency, or to make
changes which do not adversely affect the interests of holders of Rights
(excluding the interests of any Acquiring Person); provided, however, that no
supplement or amendment may be made after the earlier of the Distribution Date
and the Shares Acquisition Date which changes those provisions relating to the
principal economic terms of the Rights.

     The term "Independent Directors" means any member of the Board of Directors
of the Company who either (i) was a member of the Board on the date of the
Rights Agreement or (ii) is subsequently elected to the Board if such person is
recommended or approved by a majority of the Independent Directors, but shall
not include an Acquiring Person, or an affiliate or associate of an Acquiring
Person, or any representative of the foregoing entities.

     A copy of the Rights Agreement is filed herewith as Exhibit 4.1. The
foregoing description of the Rights does not purport to be complete and is
qualified in its entirety by reference to such Exhibit, which is hereby
incorporated herein by reference.

                                RIGHTS AGREEMENT


     Rights Agreement, dated as of October 1, 1998 between Engelhard
Corporation, a Delaware corporation (the "Company"), and ChaseMellon Shareholder
Services, L.L.C., a New Jersey limited liability company (the "Rights Agent").

                              W I T N E S S E T H :


     WHEREAS, the Board of Directors of the Company on October 1, 1998 (the
"Rights Dividend Declaration Date") authorized and declared a dividend
distribution (the "Distribution") of one Right for each outstanding share of the
Common Stock, $1.00 par value, of the Company (the "Common Stock") outstanding
at the Close of Business on November 13, 1998 (the "Record Date") and has
authorized and directed the issuance of one Right (as such number may
hereinafter be adjusted pursuant to the provisions of Section 11(p) hereof) in
respect of each share of Common Stock issued (whether originally issued or
delivered from the Company's treasury stock) between the Record Date and the
earlier of the Distribution Date or the Expiration Date (as such terms are
hereinafter defined), each Right initially representing the right to purchase,
under certain circumstances, one one-thousandth of a share of Series A Junior
Participating Preferred Stock of the Company having the rights, powers and
preferences set forth in the Certificate of Designation 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:

          (a) "Acquiring Person" shall mean any Person (as such term is
     hereinafter defined) who or which, together with all Affiliates (as such
     term is hereinafter defined) and Associates (as such term is hereinafter
     defined) of such Person, shall be the Beneficial Owner (as such term is
     hereinafter defined) of securities of the Company constituting a
     Substantial Block (as such term is hereinafter defined), but shall not
     include (i) the Company, any Subsidiary of the Company, any employee
     benefit plan of the 


<PAGE>
                                      -2-


     Company or of any Subsidiary of the Company or any Person organized,
     appointed or established by the Company or any Subsidiary of the Company
     for or pursuant to the terms of any such plan; (ii) any Person who or
     which, together with all Affiliates and Associates of such Person, becomes
     the Beneficial Owner of a Substantial Block solely as a result of a change
     in the aggregate number of shares of Voting Stock outstanding since the
     last date on which such Person acquired Beneficial Ownership of any shares
     of the Voting Stock constituting all or a portion of such Substantial
     Block; and (iii) any Person who or which, together with all Affiliates and
     Associates of such Person, becomes the Beneficial Owner of a Substantial
     Block in the good faith belief that such acquisition would not (x) cause
     such Person and its Affiliates and Associates to become the Beneficial
     Owner of a Substantial Block and such Person relied in good faith in
     computing the percentage of its voting power on publicly filed reports or
     documents of the Company 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; provided, however, that the Minorco Entities (or
     the Minorco Designee) shall not be deemed to be an Acquiring Person unless
     the Minorco Entities (or the Minorco Designee) acquire (or acquires)
     beneficial ownership of shares of Voting Stock after the date hereof that
     would make the Minorco Entities (or the Minorco Designee) the Beneficial
     Owner of the Grandfathered Percentage or more of shares of Voting Stock
     then outstanding. Notwithstanding clause (ii) or (iii) of the prior
     sentence, if any Person that is not an Acquiring Person due to such clause
     (ii) or (iii) does not cease to be the Beneficial Owner of a Substantial
     Block 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 is
     the Beneficial Owner of a Substantial Block, such Person shall, at the end
     of such five Business Day period, become an Acquiring Person (and such
     clause (ii) or (iii) shall no longer apply to such Person). For purposes of
     this definition, the determination whether any Person acted in "good faith"
     shall be conclusively determined by the Board of Directors of the Company,
     acting by a vote of those directors of the Company whose approval would be
     required to redeem the Rights under Section 23. Notwithstanding the
     foregoing, no Person shall become an "Acquiring Person" as a result of an
     acquisition of Voting Stock by the Company which, by reducing the number of
     shares of Voting Stock outstanding, increases the proportionate number of
     shares of Voting Stock 


<PAGE>
                                      -3-


     beneficially owned by such Person to 15% (or, if applicable, the
     Grandfathered Percentage with respect to such Person) or more of the shares
     of Voting Stock of the Company then outstanding; provided, however, that if
     a Person shall become the Beneficial Owner of 15% (or, if applicable, the
     Grandfathered Percentage with respect to such Person) or more of the shares
     of Voting Stock of the Company then outstanding as a result of an
     acquisition of Voting Stock by the Company and shall, after such
     acquisition of Voting Stock by the Company, become the Beneficial Owner of
     any additional Voting Stock of the Company other than pursuant to a stock
     split, stock dividend or similar transaction) and immediately thereafter be
     the Beneficial Owner of 15% (or, if applicable, the Grandfathered
     Percentage with respect to such Person) or more of the shares of Voting
     Stock then outstanding, then such Person shall be deemed to be an
     "Acquiring Person".

          (b) "Act" shall have the meaning set forth in Section 9(c) hereof.

          (c) "Adjustment Shares" shall have the meaning set forth in Section
     11(a)(ii) hereof.

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

          (e) "Agreement" shall have the meaning set forth in the introduction
     hereto.

          (f) 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 has, directly or indirectly, the right to acquire (whether
          such right is exercisable immediately or only after the passage of
          time or upon the occurrence of an event) pursuant to any agreement,
          arrangement or understanding (whether or not in writing), or upon the
          exercise of conversion rights, exchange rights, rights, warrants or
          options, or otherwise; provided, however, that a Person shall not be
          deemed the "Beneficial Owner" of, or to "beneficially own," (1)
          securities tendered pursuant 


<PAGE>
                                      -4-


          to a tender or exchange offer made by such Person or any of such
          Person's Affiliates or Associates until such tendered securities are
          accepted for purchase or exchange, (2) securities issuable upon
          exercise of Rights at any time prior to the occurrence of a Triggering
          Event or (3) securities issuable upon exercise of Rights from and
          after the occurrence of a Triggering Event, which Rights were acquired
          by such Person or any of such Person's Affiliates or Associates prior
          to the Distribution Date or pursuant to Section 3(a) hereof ("Original
          Rights") or pursuant to Section 11(i) or Section 22 hereof in
          connection with an adjustment made with respect to Original Rights; or

               (ii) which such Person or any of such Person's Affiliates or
          Associates has, directly or indirectly, the right to vote or dispose

Acquiring Person) after the date of the commencement of, or first public
announcement of the intent of any Person (other than the Company, any Subsidiary

of the Common Stock (which certificates for the Common Stock shall be deemed

the right to receive Right Certificates will be transferable only in connection

adjustment as provided herein. As of the Distribution Date, the Rights will be

<PAGE>
                                      -10-


hereto as Exhibit C (the "Summary of Rights"), by first-class, postage prepaid
mail, to each record holder of Common Stock as of the Close of Business on the
Record Date, at the address of such holder shown on the records of the Company.
With respect to certificates for Common Stock outstanding as of the Record Date,
until the Distribution Date, the Rights will be evidenced by such certificates
for Common Stock, and the registered holders of the Common Stock shall also be
the registered holders of the associated Rights. Until the Distribution Date (or
earlier redemption or expiration of the Rights), the surrender for transfer of
any of the certificates for Common Stock outstanding on the Record Date shall
also constitute the transfer of the Rights associated with the Common Stock
represented by such certificate.

     (c) Rights shall be issued in respect of all shares of Common Stock issued
after the Record Date but prior to the earlier of the Distribution Date or the
Expiration Date (as such term is defined in Section 7), or, in certain
circumstances provided in Section 22 hereof, after the Distribution Date.
Certificates representing such shares of Common Stock 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 Engelhard
         Corporation and ChaseMellon Shareholder Services, L.L.C. (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 Engelhard Corporation. Under certain circumstances, as set
         forth in the Rights Agreement, such Rights will be evidenced by
         separate certificates and will no longer be evidenced by this
         certificate. Engelhard Corporation will mail to the holder of this
         certificate a copy of the Rights Agreement as in effect on the date of
         mailing without charge within five Business Days after receipt of a
         written request therefor. Under certain circumstances set forth in the
         Rights Agreement, Rights beneficially owned by an Acquiring Person may
         become null and void.


After the due execution of any supplement or amendment to this Agreement in
accordance with the terms hereof, the reference to this Agreement in the
foregoing legend shall mean the Agreement as so supplemented or amended. Until
the Distribution Date, 


<PAGE>
                                      -11-


the Rights associated with the Common Stock represented by certificates
containing the foregoing legend shall be evidenced by such certificates alone,
and the surrender for transfer of any of such certificates shall also constitute
the transfer of the Rights associated with the Common Stock represented by such
certificate. In the event that the Company purchases or acquires any shares of
Common Stock after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Stock shall be deemed canceled and retired so
that the Company shall not be entitled to exercise any Rights associated with
the shares of Common Stock which are no longer outstanding. The failure to print
the foregoing legend on any such Common Stock certificate or any other defect
therein shall not affect in any manner whatsoever the application or
interpretation of the provisions of Section 7(e) hereof.

     Section 4. Form of Right Certificates. (a) The Right Certificates (and the
forms of election to purchase shares and of assignment to be printed on the
reverse thereof) shall be substantially the same as Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate (which do not
affect the duties and 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 or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the Rights
may from time to time be listed, or to conform to usage. The Right Certificates
shall be in machine-printable format and in a form reasonably satisfactory to
the Rights Agent. Subject to the provisions of Section 11 and Section 22 hereof,
the Right Certificates, whenever distributed, shall be dated as of the Record
Date, shall show the date of countersignature, and on their face shall entitle
the holders thereof to purchase such number of shares of Preferred Stock (or
following a Triggering Event, Common Stock, other securities, cash or other
assets, as the case may be) as shall be set forth therein at the price per one
one-thousandth of a share of Preferred Stock set forth therein (the "Purchase
Price"), but the number of such shares and the Purchase Price shall be subject
to adjustment as provided herein.

     (b) Notwithstanding any other provision of this Agreement, (i) any Right
Certificate issued pursuant to Section 3(a) or Section 22 hereof that represents
Rights beneficially owned by: (x) an Acquiring Person or any Associate or
Affiliate thereof, (y) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the 


<PAGE>
                                      -12-


Acquiring Person became such, or (z) 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 such Acquiring Person has any continuing agreement,
arrangement or understanding (whether or not in writing) regarding the
transferred Rights or (B) a transfer which the Board of Directors of the Company
has determined is part of an agreement, arrangement or understanding (whether or
not in writing) which has as a primary purpose or effect avoidance of Section
7(e) hereof, (ii) any Right Certificate issued at any time to any nominee of
such Acquiring Person, Associate or Affiliate, and (iii) provided that the
Company shall have notified the Rights Agent that this Section 4(b) applies, any
Right Certificate 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, shall contain (to the extent feasible following
the written instruction of the Company to the Rights Agent) the following
legend, modified as applicable to apply to such Person:

         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 an Associate of an Acquiring Person (as such terms are
         defined in the Rights Agreement). Accordingly, this Right Certificate
         and the Rights represented may become null and void in the
         circumstances specified in Section 7(e) of the Rights Agreement.


     Section 5. Countersignature and Registration. The Right Certificates shall
be executed on behalf of the Company by one of its authorized officers either
manually or by facsimile signature. The Right Certificates shall be
countersigned by an authorized signatory of the Rights Agent either manually or
by facsimile signature and shall not be valid for any purpose unless so
countersigned. In case any officer of the Company who shall have signed any of
the 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;
and any Right 


<PAGE>
                                      -13-


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 Agreement any such Person was not such an officer.

     In case any authorized signatory of the Rights Agent who shall have
countersigned any of the Right Certificates shall cease to be so authorized
before delivery by the Company, such Right Certificates, nevertheless, may be
issued and delivered by the Company with the same force and effect as though the
Person who countersigned such Right Certificates had not ceased to be so
authorized; and any Right Certificate may be countersigned on behalf of the
Rights Agent by any Person who, at the actual date of the countersignature of
such Right Certificate, shall be properly authorized to countersign such Right
Certificate, although at the date of the execution of this Agreement any such
Person was not so authorized.

     Following the Distribution Date and the receipt by the Rights Agent of all
relevant information, the Rights Agent will keep or cause to be kept, at its
office designated pursuant to Section 26 hereof for such purpose, books for
registration and transfer of the Right Certificates issued hereunder. Such books
shall show the names and addresses of the respective holders of the Right
Certificates, the number of Rights evidenced on its face by each of the Right
Certificates, and the date of each of the Right Certificates and the date of
countersignature of each of the Right Certificates.

     Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. Subject
to the provisions of Section 14 hereof, at any time after the Close of Business
on the Distribution Date, and at or prior to the Close of Business on the
Expiration Date, any Right Certificate or Right Certificates may be transferred,
split up, combined or ex-


<PAGE>
                                      -14-


changed for another Right Certificate or Right Certificates, entitling the
registered holder to purchase a like number of shares of Preferred Stock (or
following a Triggering Event, Common Stock, other securities, cash or other
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 Right Certificates shall make such
request in writing delivered to the Rights Agent, and shall surrender the Right
Certificate or Right Certificates to be transferred, split up, combined or
exchanged at the office of the Rights Agent designated for such purpose, along
with a signature guarantee and such other and further documentation as the
Rights Agent may reasonably request. 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, as the Company shall reasonably request, of the identity of the
Beneficial Owner, Affiliates or Associates thereof or of the holder, or of any
other Person with which such holder or any of such holder's Affiliates or
Associates has any agreement, arrangement or understanding (whether or not in
writing) for the purpose of acquiring, holding, voting or disposing of
securities of the Company. Thereupon the Rights Agent shall, subject to Section
4(b), Section 7(e), Section 14 and Section 20(k) hereof, countersign and deliver
to the Person entitled thereto a Right Certificate or Right Certificates, as the
case may be, as so requested. The Company may require payment from a Right
Certificate holder of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer, split up, combination or
exchange of Right Certificates. The Rights Agent shall have no duty or
obligation under this Section unless and until it is satisfied that all such
taxes and/or charges have been or will be paid.

     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, along with a signature guarantee and such other
further documentation as the Rights Agent may reasonably request and
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 delivery to the
registered owner in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

Stock pursuant to the exercise of a Right shall initially be $100, and shall be

shall thereupon, subject to Section 20(k), promptly (i) requisition from any
transfer agent of Preferred Stock certificates for the number of one
one-thousandths of shares of Preferred Stock to be purchased and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests, (ii) 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 shares 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 hereby directs the depositary agent to comply with such request,

Right Certificate, registered in such name or names as may be designated by such
holder and (vi) when appropriate, after receipt promptly deliver such cash to or
upon the order of the registered holder of such Right Certificate. The payment
of the then Purchase Price may be made in cash or by certified bank check or
bank draft or money order payable to the order of the Company or the Rights
Agent. In the event that the Company is obligated to issue securities,
distribute property or pay cash pursuant to Section 11(a)(iii) hereof, the
Company will make all arrangements necessary so that cash, property or
securities are available for issuance, distribution or payment by the Rights
Agent, if and when necessary to comply with this Agreement.

     (d) In case the registered holder of any Right Certificate shall exercise
less than all the Rights evidenced thereby, a new Right Certificate evidencing
Rights equivalent to the Rights remaining unexercised shall be issued by the
Rights Agent to the registered holder of such Right Certificate or to his duly
authorized assigns, subject to the provisions of Section 6 and 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 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 became 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
(whether or not in writing) regarding the transferred Rights or (B) a transfer
which the Board of Directors of the Company has determined is a part of an
agreement, arrangement or understanding (whether or not in writing) 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 notify the Rights Agent when
this Section 7(e) applies and shall use all reasonable efforts to insure that
the provisions of this Section 7(e) and Section 4(b) hereof are complied with,
but neither the Company nor the 


<PAGE>
                                      -17-


Rights Agent shall have any liability to any holder of Right Certificates or
other Person as a result of the Company's failure to make any determinations
with respect to an Acquiring Person or its Affiliates, Associates or transferees
hereunder.

     (f) Notwithstanding anything in this Agreement to the contrary, neither the
Rights Agent nor the Company shall be obligated to undertake any action with
respect to a registered holder upon the occurrence of any purported exercise as
set forth in this Section 7 unless such registered holder shall have (i)
properly 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, Affiliates or Associates thereof or of the holder, or of
any other Person with which such holder or any of such holder's Affiliates or
Associates has any agreement, arrangement or understanding (whether or not in
writing) for the purpose of acquiring, holding, voting or disposing of any
securities of the Company 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 canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Right
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this 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
canceled Right Certificates to the Company, or shall, at the written request of
the Company, destroy such canceled Right Certificates, and in such case shall
deliver a certificate of destruction thereof to the Company.

     Section 9. Reservation and Availability of Shares 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 


<PAGE>
                                      -18-


its authorized and unissued shares of Common Stock and/or other securities) or
out of its authorized and issued shares of Preferred Stock (and, following the
occurrence of a Triggering Event, out of its authorized and issued Common Stock
and/or other securities) held in its treasury, the number of shares of Preferred
Stock (and, following the occurrence of a Triggering Event, Common Stock and/or
other securities) that will be sufficient to permit the exercise in full of all
outstanding Rights (it being understood that any of the foregoing shares or
securities may also be reserved for other purposes) or will take such other
steps as are appropriate to assure that the number of such shares or securities
(or their equivalents) sufficient to permit the exercise in full of all
outstanding Rights will be available upon such exercise.

     (b) So long as the shares of Preferred Stock (and, following the occurrence
of a Triggering Event, Common Stock and/or other securities) issuable upon the
exercise of Rights may be listed on any national securities exchange, the
Company shall use its best efforts to cause, from and after such time as the
Rights become exercisable (but only to the extent that the Company determined
that it is reasonably likely that the Rights will be exercised), all shares
reserved for such issuance to be listed on such exchange upon official notice of
issuance upon such exercise.

     (c) The Company shall use its best efforts (X) (i) to file, as soon as
practicable following the first occurrence of a Section 11(a)(ii) Event, or as
soon as required by law, 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) to cause
such registration statement to become effective as soon as practicable after
such filing, and (iii) to 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 which the Rights are no longer exercisable for
such securities, and (B) the Expiration Date and (Y) (i) to file appropriate
applications with any state or federal regulatory bodies having jurisdiction
over the issuance of the securities (or assets) purchasable upon exercise of the
Rights in order to obtain any approvals or orders of such bodies as may be
legally required, (ii) to cause such approvals to be obtained or orders to be
issued as soon as practicable after such filing and (iii) to cause such
approvals or orders to remain effective until the earlier of (A) the date as of
which the Rights are no longer exercisable for such securities (or assets), and
(B) the Expiration Date, to the extent not previously obtained. The Company will
also take such action as may be appropriate under the blue sky laws of the
various states. The Company may temporarily suspend, (X) for a pe-


<PAGE>
                                      -19-


riod of time not to exceed ninety (90) days after the date set forth in clause
(X)(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 and (Y) for a period of time not in excess of 180 days after
such date (or for such longer period as is required by any applicable law, rule
or regulation of any appropriate regulatory bodies), the exercisability of the
Rights in order to obtain any such required regulatory body approvals or orders.
Upon any such suspension, the Company shall issue a public announcement and
shall give simultaneous written notice to the Rights Agent stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement and notice to the Rights Agent at such time as the suspension is no
longer in effect. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction unless the
requisite qualifications in such jurisdiction shall have been obtained.

     (d) The Company covenants and agrees that it will take all such action as
may be necessary to ensure that all shares of the Preferred Stock (and following
the occurrence of a Triggering Event, Common Stock and/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 federal and state taxes and charges which may be payable in
respect of the issuance or delivery of the Right Certificates or of any shares
of the Preferred Stock (or Common Stock and/or other securities, as the case may
be) upon the exercise of Rights. The Company shall not, however, be required (a)
to pay any tax or charge which may be payable in respect of any transfer
involved in the transfer or delivery of Right Certificates or the issuance or
delivery of certificates for the Preferred Stock (or Common Stock and/or other
securities, as the case may be) in a name other than that of the registered
holder of the Right Certificate evidencing Rights surrendered for exercise or
(b) to issue or deliver any certificates for shares of the Preferred Stock (or
Common Stock and/or other securities, as the case may be) 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 in whose name any
certificate for any number of shares of Preferred Stock (or Common Stock and/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
whole and/or fractional shares of Preferred Stock (or Common Stock and/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 and shall show the date of countersignature; provided,
however, that if the date of such surrender and payment is a date upon which the
Preferred Stock (or Common Stock and/or other securities, as the case may be)
transfer books of the Company are closed, such Person shall be deemed to have
become the record holder of such shares on, and such certificate shall be dated,
the next succeeding Business Day on which the Preferred Stock (or Common Stock
and/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 of Shares or Number of
Rights. The Purchase Price, the number of shares covered by each Right and the
number of Rights outstanding are subject to adjustment from time to time as
provided in this Section 11.

     (a)(i) In the event the Company shall at any time after the date of this
Agreement (A) declare a dividend on the Preferred Stock payable in shares of the
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, 


<PAGE>
                                      -21-


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 Purchase Price then in effect the aggregate number and kind of shares of
capital stock which, if such Right had been exercised immediately prior to such
date and at a time when the Preferred Stock (or Common Stock and/or other
securities) transfer books of the Company were open, he or she 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 would
require an adjustment under both this Section 11(a)(i) and Section 11(a)(ii),
the adjustment provided for in this Section 11(a)(i) shall be in addition to,
and shall be made prior to, any adjustment required pursuant to Section
11(a)(ii).

     (ii) Subject to Section 24 of this Agreement, in the event any Person,
alone or together with its Affiliates and Associates, becomes an Acquiring
Person except as the result of a transaction set forth in Section 13(a) hereof
(any such event, a "Section 11(a)(ii) Event"), then, prior to the later of (x)
the date on which the Company's rights of redemption pursuant to Section 23(a)
expire, or (y) five (5) days after the date of the first occurrence of a Section
11(a)(ii) Event, proper provision shall be made so that each holder of a Right,
except as provided in Section 7(e) hereof, shall thereafter have a right to
receive, upon exercise thereof at the then current Purchase Price for the number
of one one-thousandths of a share of Preferred Stock for which such Right is
then exercisable in accordance with the terms of this Agreement, in lieu of
shares of Preferred Stock, such number of shares of the Common Stock of the
Company as shall equal the result obtained by (x) multiplying the then current
Purchase Price by the then number of one one-thousandths of a share of Preferred
Stock for which a Right is then exercisable and dividing that product by (y) 50%
of the Current Market Price per share of the Common Stock of the Company
(determined pursuant to Section 11(d)) on the date of the occurrence of the
event listed above in this subparagraph (ii) (such number of shares are
hereinafter referred to as the "Adjustment Shares") provided that the Purchase
Price and the number of Adjustment Shares shall be further adjusted as provided
in this Agreement to reflect any events occurring after the date of such first
occurrence.

     (iii) In the event that the number of shares of 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 are
not suffi-


<PAGE>
                                      -22-


cient to permit the exercise in full of the Rights in accordance with the
foregoing subparagraph (ii), 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, the "Spread"), and
(B) with respect to each Right, make adequate provision to substitute for the
Adjustment Shares, upon exercise of the Rights and payment of the applicable
Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common
Stock 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, "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, however, if the Company shall not have made
adequate provision to deliver value pursuant to clause (B) above within thirty
(30) days following the later of (x) the first occurrence of a Section 11(a)(ii)
Event and (y) the date on which the Company's right of redemption pursuant to
Section 23(a) expires (the later of (x) and (y) being referred to herein as the
"Section 11(a)(ii) Trigger Date"), 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 (to the extent available)
and then, if necessary, cash, which shares and/or cash have an aggregate value
equal 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
could be authorized for issuance upon exercise in full of the Rights, the thirty
(30) day period set forth above may be extended to the extent necessary, but not
more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order
that the Company may seek shareholder approval for the authorization of such
additional shares (such period, as it may be extended, the "Substitution
Period"). To the extent that the Company determines that some action need be
taken pursuant to the first and/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 and/or to decide the
appropriate form of distribution to be made pur-


<PAGE>
                                      -23-


suant to such first sentence and to determine the value thereof. In the event of
any such suspension, the Company shall issue a public announcement and shall
give simultaneous written notice to the Rights Agent stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement and notice to the Rights Agent at such time as the suspension is no
longer in effect. 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 Section 11(a)(ii)
Trigger Date and the value of any Common Stock Equivalent shall be deemed to
have the same value as the Common Stock on such date. The Company shall give the
Rights Agent notice of the selection of any Common Stock Equivalent under this
Section 11(a)(iii).

     (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 (for a
period expiring within 45 calendar days after such record date) to subscribe for
or purchase Preferred Stock (or securities having substantially the same rights,
privileges and preferences as the shares of Preferred Stock ("Equivalent
Preferred Stock") or convertible into the Preferred Stock or Equivalent
Preferred Stock) at a price per share of the Preferred Stock or Equivalent
Preferred Stock (or having a conversion price per share, if a security
convertible into the Preferred Stock or Equivalent Preferred Stock) less than
the Current Market Price (as defined in Section 11(d)) per share of the
Preferred Stock or Equivalent Preferred Stock, as the case may be, on such
record date, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, of which the numerator shall be the number of shares
of Preferred Stock outstanding on such record date plus the number of shares of
Preferred Stock or Equivalent Preferred Stock which the aggregate offering price
of the total number of shares of Preferred Stock or Equivalent Preferred Stock
so to be offered (and/or the aggregate initial conversion price of the
convertible securities so to be offered) would purchase at such Current Market
Price and of which the denominator shall be the number of shares of Preferred
Stock outstanding on such record date plus the number of additional shares of
Preferred Stock and/or Equivalent Preferred Stock to be offered for subscription
or purchase (or into which the convertible securities so to be offered are
initially convertible). In case such subscription price may be paid by delivery
of consideration part or all of which shall be in a form other than cash, the
value of such consideration 


<PAGE>
                                      -24-


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. Shares of Preferred Stock owned by or held for the account of the Company
shall not be deemed outstanding for the purpose of any such computation. Such
adjustment shall be made successively whenever such a record date is fixed; and
in the event that such rights, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

     (c) In case the Company shall fix a record date for the making of a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing or surviving corporation) of evidences of indebtedness or assets
(other than a regular periodic cash dividend or a dividend payable in Preferred
Stock) or subscription rights or warrants (excluding those referred to in
Section 11(b)), the Purchase Price to be in effect after such record date shall
be determined by multiplying the Purchase Price in effect immediately prior to
such record date by a fraction, of which the numerator shall be the Current
Market Price per share of Preferred Stock (as defined in Section 11(d)) on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to one share of Preferred Stock and of which the denominator shall be
such Current Market Price per share of Preferred Stock. Such adjustments shall
be made successively whenever such a record date is fixed; and in the event that
such distribution is not so made, the Purchase Price shall again be adjusted to
be the Purchase Price 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), the "Current Market Price" per
share of Common Stock on any date shall be deemed to be the average of the daily
closing prices per share of such Common Stock for the 30 consecutive Trading
Days (as such term is hereinafter defined in this paragraph (d)) immediately
prior to and not including such date and for purposes of computations made
pursuant to Section 11(a)(iii) hereof, the "Current Market Price" per share of
Common Stock on any date shall be deemed to be the average of the daily closing
prices per share of such Common Stock for the ten 


<PAGE>
                                      -25-


(10) consecutive Trading Days immediately following and not including such date;
provided, however, that in the event that the Current Market Price per share of
Common Stock is determined during the period following the announcement by the
issuer of such Common Stock of (A) a dividend or distribution on such Common
Stock payable in shares of such Common Stock or securities convertible into
shares of such Common Stock (other than the Rights) or (B) any subdivision,
combination or reclassification of such Common Stock, and prior to the
expiration of the requisite 30 Trading Day or 10 Trading Day period, as set
forth above after the ex-dividend date for such dividend or distribution or the
record date for such subdivision, combination or reclassification, then, and in
each such case, the Current Market Price shall be appropriately adjusted to take
into account ex-dividend trading. The closing price for each day shall be the
last sale price, regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the shares of the Common Stock are not listed or admitted to trading on the
New York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the shares of the Common Stock are listed or
admitted to trading or, if the shares of the Common Stock are not listed or
admitted to trading on any national securities exchange, the last quoted price
or, if not so quoted, the average of the high bid and low asked prices in the
over-the-counter market, as reported by The Nasdaq Stock Market, Inc. ("Nasdaq")
or such other system then in use, or, if on any such date the shares of the
Common Stock are not quoted by such organization, the average of the closing bid
and asked prices as furnished by a professional market maker making a market in
the Common Stock selected by the Board of Directors of the Company. If on any
such date no market maker is making a market in the Common Stock, the fair value
of such shares on such date shall be as determined by an independent investment
banking firm selected by the Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent and shall be conclusive for
all purposes. The term "Trading Day" shall mean a day on which the principal
national securities exchange on which the shares of Common Stock are listed or
admitted to trading is open for the transaction of business or, if the shares of
the Common Stock are not listed or admitted to trading on any national
securities exchange, a Monday, Tuesday, Wednesday, Thursday or Friday on which
banking institutions in the State of New York are not 


<PAGE>
                                      -26-


authorized or obligated by law or executive order to close. If the Common Stock
is not publicly held or not so listed or traded, "Current Market Price" per
share shall mean the fair value per share as determined by an independent
investment banking firm selected by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be conclusive for all purposes.

     (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 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 provided above or if the
Preferred Stock is not publicly held or listed or traded in any manner described
in clause (i) of this Section 11(d), the "Current Market Price" per share of
Preferred Stock shall be conclusively deemed to be an amount equal to 1000 (as
such number may be appropriately adjusted for such events as stock splits, stock
dividends and recapitalizations with respect to the Common Stock occurring after
the date of this Agreement) multiplied by the Current Market Price per share of
the Common Stock. If neither the Common Stock nor the Preferred Stock is
publicly held or so listed or traded, "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, whose 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-thousandths of a share of Preferred Stock shall be equal to the "Current
Market Price" of one share of Preferred Stock divided by 1000.

     (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 such price; provided, however, that any
adjustments which by reason of this Section 11(e) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Section 11 shall be made to the nearest cent or to
the nearest one ten-thousandth of a share of Common Stock or one one-millionth
of a share of Preferred Stock, as the case may be. Notwithstanding the first
sentence of this Section 11(e), any adjustment required by this Section 11 shall
be made no later than the earlier of (i) three years from the date of the
transaction which mandates such adjustment or (ii) the Expiration Date.


<PAGE>
                                      -27-


     (f) If as a result of an adjustment made pursuant to Section 11(a) or
Section 13(a), the holder of any Right thereafter exercised shall become
entitled to receive 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 shares contained in Section 11(a) through (q),
inclusive, 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.

     (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-thousandths 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 shares (calculated to
the nearest one one-millionth) obtained by (i) multiplying (x) the number of
shares covered by a Right immediately prior to this adjustment by (y) the
Purchase Price in effect immediately prior to such adjustment of the Purchase
Price and (ii) dividing the product so obtained by the Purchase Price in effect
immediately after such adjustment of the Purchase Price.

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

                                      -28-


the Purchase Price. The Company shall make a public announcement and shall give
simultaneous written notice to the Rights Agent of its election to adjust the
number of Rights, indicating the record date for the adjustment to be made. This
record date may be the date on which the Purchase Price is adjusted or any day
thereafter, but, if the Right Certificates have been issued, shall be at least
10 days later than the date of the public announcement. If Right Certificates
have been issued, upon each adjustment of the number of Rights pursuant to this
Section 11(i), the Company shall, as promptly as practicable, cause to be
distributed to holders of Right Certificates on such record date Right
Certificates evidencing, subject to Section 14, 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 shares 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 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 one one-thousandth of the then stated value, if any, 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-thousandths of a share of such 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 


<PAGE>
                                      -29-


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

     (m) Anything 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 the Board of Directors of the Company shall determine to be
advisable in order that any consolidation or subdivision of shares of Preferred
Stock, issuance wholly for cash of any of shares of Preferred Stock at less than
the Current Market Price, issuance wholly for cash of the 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 hereinabove in this Section 11, hereafter made by the Company to
holders of its Preferred Stock shall not be taxable to such stockholders.

     (n) The Company covenants and agrees that, after the Distribution Date, it
will not, except as permitted by Sections 23, 24 and 27 hereof, take (nor will
it permit any of its Subsidiaries to take) any action if at the time such action
is taken it is reasonably foreseeable that such action will diminish
substantially or otherwise eliminate the benefits intended to be afforded by the
Rights.

     (o) The Company covenants and agrees that it shall not, at any time after
the Distribution Date, (i) consolidate with any other Person (other than a
Subsidiary of the Company in a transaction which complies with Section 11(n)),
(ii) merge with or into any other Person (other than a Subsidiary of the Company
in a transaction which complies with Section 11(n)), or (iii) sell or transfer
(or permit any of its Subsidiaries to sell or transfer), in one or more
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to, any
other Person or Persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(n)) if (x) at
the time of or immediately after such consolidation, merger or sale there are

<PAGE>
                                      -30-


any rights, warrants or other instruments or securities outstanding or
agreements 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 the Person who constitutes, or would constitute, the "Principal
Party" for 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.

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

     (q) Notwithstanding anything in this Agreement to the contrary, prior to
the Distribution Date, the Company may, in lieu of making any adjustment to the
Purchase Price, to the number of shares of Preferred Stock eligible for purchase
on exercise of each Right or to the number of Rights outstanding, which
adjustment would otherwise be required by Section 11(a)(i), 11(b), 11(c), 11(h)
or 11(i), make such other equitable adjustment or adjustments thereto as the
Board of Directors (whose determination shall be conclusive) deems appropriate
in the circumstances and not inconsistent with the objectives of the Board of
Directors in adopting this Agreement and such Sections.

     Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 or 13 hereof, the
Company shall (a) promptly prepare a certificate setting forth such adjustment,
and a brief reasonably detailed statement of the facts and com-


<PAGE>
                                      -31-


putations accounting for such adjustment and the adjusted Purchase Price, (b)
promptly file with the Rights Agent and with each transfer agent for the
Preferred Stock and the Common Stock a copy of such certificate and (c) mail a
brief summary thereof to each holder of a Right Certificate in accordance with
Section 26 hereof. The Rights Agent shall be fully protected in relying on any
such certificate and on any adjustment therein contained and shall have no duty
with respect to and shall not be deemed to have knowledge of any adjustment
unless and until it shall have received such certificate.

     Section 13. Consolidation, Merger or Sale or Transfer of Assets or Earning
Power. (a) In the event that, following the Shares Acquisition Date, directly or
indirectly, (x) the Company shall consolidate with, or merge with and into, any
other Person, (y) any Person shall consolidate with the Company, or merge with
and into the Company and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such
consolidation or merger, all or part of the 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 or more
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons other than the Company or any of its wholly owned
Subsidiaries (any such event, a "Section 13 Event"), 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)) 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 issued, fully paid, non-assessable and
freely tradable shares of Common Stock of the Principal Party (as hereinafter
defined), not subject to any liens, encumbrances, rights of call or first
refusal, or other adverse claims as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the then number of one
one-thousandths of a share of Preferred Stock for which a Right is exercisable
immediately prior to the first occurrence of a 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 one one-thousandths 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 a Sec-


<PAGE>
                                      -32-


tion 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 per
share of the Common Stock of such Principal Party (determined in the manner
described in Section 11(d)) 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 Section 13 Event, 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 shall thereafter apply
to such Principal Party; (iv) such Principal Party shall take such steps
(including, but not limited to, the reservation of a sufficient number of shares
of its Common Stock in accordance with Section 9) in connection with such
consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to the
shares of its Common Stock thereafter deliverable upon the exercise of the
Rights; and (v) the provisions of Section 11(a)(ii) hereof shall be of no effect
following the first occurrence of any Section 13 Event. (b) "Principal Party"
shall mean

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

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

provided, however, that in either 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) if 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 


<PAGE>
                                      -33-


the issuer of the Common Stock having the greatest market value.

     (c) The Company shall not consummate any Section 13 Event unless all
regulatory approvals for the consummation of such Section 13 Event and the
exercise of the Rights in accordance with the terms of this Agreement have been
obtained and the Principal Party shall have a sufficient number of authorized
shares of its Common Stock which are neither outstanding nor 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 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, will use its best efforts to cause such
     registration statement to become effective as soon as practicable after
     such filing and will use its best efforts to cause such registration
     statement to remain effective (with a prospectus at all times meeting the
     requirements of the Act) until the Expiration Date; and

          (ii) 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 under the
     Exchange Act.

The provisions of this Section 13 shall similarly apply to successive Section 13
Events. In the event that a 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 or to distribute Right Certificates
which evidence fractional Rights. In lieu of such fractional Rights, the Company
shall pay to the registered holders of the Right Certificates 


<PAGE>
                                      -34-


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

     (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are integral multiples of one
one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares (other than fractions
which are integral multiples of one one-thousandth of a share of Preferred
Stock). In lieu of fractional shares that are not integral multiples of one
one-thousandth of a share of Preferred Stock, the Company may pay to the
registered holders of Right Certificates at the time the Rights evidenced
thereby are exercised or exchanged as herein provided an amount in cash equal to
the same fraction of the current market value of one one-thousandth of a share
of Preferred Stock. For purposes of this Section 14(b), the current market value
of one one-thousandth of a share of Preferred Stock shall be one one-thousandth
of the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)(ii)) for the Trading Day immediately prior to the date of such
exercise.


<PAGE>
                                      -35-


     (c) Following the occurrence of a Triggering Event the Company shall not be
required to issue fractions of shares of Common Stock upon exercise of the
Rights or to distribute certificates which evidence fractional shares of Common
Stock. In lieu of fractional shares of Common Stock, 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 (1) 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 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 Rights expressly waives
his right to receive any fractional Rights or any fractional shares upon
exercise of a Right, except as otherwise permitted by this Section 14.

     (e) Whenever a payment for fractional Rights or fractional shares is to be
made by the Rights Agent, the Company shall (i) promptly prepare and deliver to
the Rights Agent a certificate setting forth in reasonable detail the facts
related to such payment and the prices and/or formula utilized in calculating
such payments, and (ii) provide sufficient monies to the Rights Agent in the
form of fully collected funds to make such payments. The Rights Agent shall be
fully protected in relying upon such a certificate and shall have no duty with
respect to and shall not be deemed to have knowledge of any payments for
fractional Rights or fractional shares under this Section 14 unless and until it
shall have received such a certificate and sufficient monies.

     Section 15. Rights of Action. All rights of action in respect of this
Agreement are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Stock), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in his own behalf and for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce, or otherwise act 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 specifi-


<PAGE>
                                      -36-


cally acknowledged that the holders of Rights would not have an adequate remedy
at law for any breach of this Agreement and will be entitled to specific
performance of the obligations hereunder and injunctive relief against actual or
threatened violations of the obligations hereunder of any Person subject to this
Agreement.

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

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

          (b) after the Distribution Date, the Right Certificates are
     transferable only on the registry books of the Rights Agent if surrendered
     at the office of the Rights Agent designated for such purpose, duly
     endorsed or accompanied by a proper instrument of transfer and with the
     appropriate forms and certificates fully executed, along with a signature
     guarantee and such other and further documentation as the Rights Agent may
     reasonably request;

          (c) subject to Section 6 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) is registered as the absolute owner thereof and of the
     Rights evidenced thereby (notwithstanding any notations of ownership or
     writing on the Right Certificates or the associated 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 required to be affected by any notice to the contrary;

          (d) notwithstanding anything in this Agreement to the contrary,
     neither the Company nor the Rights Agent shall have any liability to any
     holder of a Right or other Person as a result of its inability to perform
     any of its obligations under this Agreement by reason of any preliminary or
     permanent injunction or other order, decree, judgment or ruling (whether
     interlocutory or final) 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 


<PAGE>
                                      -37-


     or enacted by any governmental authority, prohibiting or otherwise
     restraining performance of such obligation; provided, however, the Company
     must use its best efforts to have any such order, decree, judgment 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 shares 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 shareholder of the Company or
any right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25), or to receive dividends or
subscription rights, or otherwise, until the Right or Rights evidenced by such
Right Certificate shall have been exercised in accordance with the provisions
hereof.

     Section 18. Concerning the Rights Agent. The Company agrees to pay to the
Rights Agent reasonable compensation for all services rendered by it hereunder
and, from time to time, on demand of the Rights Agent, its reasonable expenses
and counsel fees and other disbursements incurred in the preparation, execution,
delivery, amendment, administration and execution of this Agreement and the
exercise and performance of its duties hereunder. The Company also agrees to
indemnify the Rights Agent for, and to hold it harmless against, any loss,
liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or
expense, incurred without gross negligence, bad faith or willful misconduct on
the part of the Rights Agent (including the reasonable fees and expenses of
counsel), for any act 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 in the premises. Anything to the contrary notwithstanding, in no event
shall the Rights Agent be liable for special, 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.


<PAGE>
                                      -38-


     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 the acceptance and administration of this Agreement in reliance
upon any Right Certificate or certificate for Common Stock or for other
securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
instruction, adjustment notice, 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.

     In addition to the foregoing, the Rights Agent shall be protected and shall
incur no liability for, or in respect of, any action taken or omitted by it in
connection with its administration of this Agreement in reliance upon (i) the
proper execution of the certification concerning beneficial ownership appended
to the Form of Assignment and the Form of Election to Purchase included as part
of Exhibit B hereto (the "Certification"), unless the Rights Agent shall have
actual knowledge that, as executed, the Certification is untrue or (ii) the
non-execution or failure to complete the Certification including, without
limitation, any refusal to honor any otherwise permissible assignment or
election by reason of such non-execution or failure.

     Section 19. Merger or Consolidation or Change of Name of Rights Agent. Any
Person into which the Rights Agent or any successor Rights Agent may be merged
or with which it may be consolidated, or any Person resulting from any merger or
consolidation to which the Rights Agent or any successor Rights Agent shall be a
party, or any 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 any
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.

     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 


<PAGE>
                                      -39-


in all such cases such Right Certificates shall have the full force provided in
the Right Certificates and in this Agreement.

     Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties
and obligations, and only the duties and obligations, expressly imposed by this
Agreement (and no implied duties or obligations) 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 the 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
     and the Rights Agent shall incur no liability for or in respect of 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
     be proved or established by the Company prior to taking, suffering or
     omitting any action hereunder, such fact or matter (unless other evidence
     in respect thereof be herein specifically prescribed) may be deemed to be
     conclusively proved and established by a certificate signed by any one of
     the Chairman of the Board, the President, any Vice President, the Treasurer
     or the Secretary of the Company and delivered to the Rights Agent; and such
     certificate shall be full authorization and protection to the Rights Agent
     and the Rights Agent shall incur no liability for or in respect of any
     action taken, suffered or omitted 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. The issuance or non-issuance
     of a Right Certificate or Preferred Stock or other security issued in lieu
     of Preferred Stock in accordance with instructions given to the Rights
     Agent by the Company pursuant to Section 20(k) hereof or in accordance with
     the terms hereof shall not constitute 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 


<PAGE>
                                      -40-


     (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 adjustment required under any provisions of this
     Agreement, including Sections 11 or 13 or responsible for the manner,
     method or amount of any such adjustment 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 Preferred Stock or Common Stock to be issued
     pursuant to this Agreement or any Right Certificate or as to whether any
     shares of Preferred Stock or Common 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 and
     certificates delivered pursuant to any provision hereof from any one of the
     Chairman of the Board, the President, any Vice President, the Secretary or
     the Treasurer of the Company, and is authorized to apply to such officers
     for advice or instructions in connection with its duties, and such
     instructions shall be full authorization and protection to the Rights Agent
     and the Rights Agent shall incur no liability for or in respect of any
     action taken, suffered or omitted to be taken by it in good faith in
     accordance with instructions of any such officer. An application by the

<PAGE>
                                      -41-


     Rights Agent for instructions may set forth in writing any action proposed
     to be taken or omitted by the Rights Agent with respect to its duties and
     obligations under this Agreement and the date on and/or after which such
     action shall be taken, and the Rights Agent shall not be liable or
     responsible for any action taken, suffered or omitted in accordance with a
     proposal included in any such application on or after the date specified
     therein (which date shall not be less than one Business Day after the
     Company receives such application) without the consent of the Company
     unless prior to taking or omitting or suffering such action, the Rights
     Agent has received written instructions in response to an application
     specifying the actions to be taken or omitted. The Rights Agent may rely
     conclusively on the most recent written instructions provided by any such
     officer.

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

          (i) The Rights Agent may execute and exercise any of the rights or
     powers hereby vested in it or perform any duty hereunder either by 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 or any other
     Person resulting from any such act, default, neglect or misconduct, absent
     negligence, bad faith or willful misconduct in the selection 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 it reasonably believes that repayment of such funds or adequate
     indemnification against such risk or liability is not reasonably assured to
     it.

          (k) If, with respect to any Rights Certificate surrendered to the
     Rights Agent for exercise or transfer, the 


<PAGE>
                                      -42-


     certificate attached to the form of assignment or form of election to
     purchase, as the case may be, has either not been completed or indicates an
     affirmative response, the Rights Agent shall not take any further action
     with respect to such requested exercise or transfer without first
     consulting the Company. The Company shall give the Rights Agent prompt
     written instructions as to the action to be taken regarding the Rights
     Certificates involved. The Rights Agent shall not be responsible or liable
     for acting in accordance with such instructions.

     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 thirty (30) days' notice in writing mailed to the Company and to each
transfer agent of the Preferred Stock and the Common Stock by registered or
certified mail, and, at the Company's expense, to the holders of the Right
Certificates by first class mail. The Company may remove the Rights Agent or any
successor Rights Agent upon thirty (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 Preferred Stock and the Common Stock by registered or certified
mail, and to the holders of the Right Certificates by first-class mail. If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of thirty (30) days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Right Certificate (who shall, with such notice, submit his
Right Certificate for inspection by the Company), then the Company shall become
the temporary Rights Agent and 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 Person organized and doing business under the laws of
the United States or of the State of New York (or of any other state of the
United States so long as such Person is authorized to do business in the State
of New York), in good standing, having an office in the State of New York, 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 $25 million. After appointment, the successor Rights Agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Rights Agent 


<PAGE>
                                      -43-


     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 Preferred Stock
     and the Common Stock, and 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.
     In case at the time such successor Rights Agent shall succeed to the agency
     created by this Agreement, any of the Right Certificates shall have been
     countersigned but not delivered, any such successor Rights Agent may adopt
     the countersignature of the predecessor 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.

     Section 22. Issuance of New Right Certificates. Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary, the Company may,
at its option, issue new Right Certificates evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Right Certificates made in accordance with the
provisions of this Agreement. In addition, in connection with the issuance or
sale of shares of Common Stock following the Distribution Date and prior to the
redemption or expiration the Rights, the Company (a) shall, with respect to
shares of Common Stock 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 hereinafter 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, however,
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
Per-


<PAGE>
                                      -44-


son 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 and Termination. (a) The Board of Directors of the
Company may, at its option, at any time prior to the earlier of (x) the Close of
Business on the tenth calendar day following the Shares Acquisition Date (or if
the Shares Acquisition Date shall have occurred prior to the Record Date, the
Close of Business on the tenth day following the Record Date), or (y) the Close
of Business on the Final Expiration Date, redeem all but not less than all of
the then outstanding Rights at a redemption price of $.001 per Right as
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "Redemption Price"), and the Company may, at its
option, pay the Redemption Price either in shares of its Common Stock (valued at
their Current Market Price as defined in Section 11(d)(i) on the date of the
redemption), other securities, cash or other assets. The redemption of the
Rights by the Board of Directors of the Company may be made effective at such
time, on such basis and subject to such conditions as the Board of Directors in
its sole discretion may establish. Notwithstanding anything contained 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.

     (b) Immediately upon the action of the Board of Directors of the Company
ordering the redemption of the Rights, 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 held. Within 10 days after the action of the Board of
Directors ordering the redemption of the Rights, the Company shall give notice
of such redemption to the holders of the then outstanding Rights by mailing such
notice to the Rights Agent and to all such holders at their last addresses as
they appear upon the registry books of the Rights Agent or, prior to the
Distribution Date, on the registry books of the transfer agent for the Common
Stock. Any notice 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 pur-

                                      -45-


chase for value any Rights at any time in any manner other than that
specifically set forth in this Section 23, and other than in connection with the
repurchase of Common Stock prior to the Distribution Date.

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

     Section 24. Exchange. (a) The Board of Directors of the Company may, at its
option, at any time and from time to time on or after a Section 11(a)(ii) Event,
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 at an exchange ratio of one
share of 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 Section 24(a) 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 equal to the number of such
Rights held by such holder multiplied by the Exchange Ratio. Promptly after the
action of the Board of Directors ordering an exchange of the Rights, the Company
shall give notice of any such exchange to the Rights Agent and the holders of
the then outstanding Rights by mailing such notice to all such holders at each
holder's last address as it appears upon the registry books of the Rights Agent;
provided, however, that the failure to give, or any defect in, such notice shall
not affect the validity of such exchange. 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 for Rights will be ef-


<PAGE>
                                      -46-


fected and, in the event of any partial exchange, the number of Rights which
will be exchanged. Any partial exchange shall be effected pro rata based on the
number of Rights (other than Rights which have become void pursuant to the
provisions of Section 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 Equivalent Preferred Stock,
as such term is defined in Section 11(b) hereof) for shares of Common Stock
exchangeable for the Rights, at the initial rate of one one-thousandth of a
share of Preferred Stock (or Equivalent Preferred Stock) for each share of
Common Stock, as appropriately adjusted to reflect adjustments in the dividend
rights of the Preferred Stock pursuant to the terms thereof.

     (d) In the event that there shall not be sufficient shares of Common Stock
or Preferred Stock issued, but not outstanding, or authorized but unissued, to
permit any exchange of Rights as contemplated in accordance with this Section 24
or that any regulatory actions or approvals are required in connection
therewith, the Company shall take all such action as may be necessary to
authorize additional Common Stock or Preferred Stock for issuance upon exchange
of the Rights.

     (e) The Company shall not be required to issue fractional shares of Common
Stock or to distribute certificates which evidence fractional shares of Common
Stock pursuant to this Section 24. In lieu of such fractional shares of Common
Stock, the Company shall pay to the registered holders of the Right Certificates
with regard to which such fractional shares of Common Stock 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. For the purposes of this Section 24(e),
the current market value of a whole share of Common Stock shall be the closing
price of a share of Common Stock (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

     (f) In any exchange pursuant to this Section 24, the Company, at its
option, may substitute for any share of Common Stock exchangeable for a Right
(i) Common Stock Equivalents, (ii) cash, (iii) debt securities of the Company,
(iv) other assets, or (v) any combination of the foregoing, having an aggregate
value which the Board of Directors of the Company shall have determined in good
faith to be equal to the Current Market Price of one share of Common Stock
(determined pursuant to Sec-


<PAGE>
                                      -47-


tion 11(d) hereof) on the Trading Date immediately preceding the date of
exchange pursuant to this Section 24.

     Section 25. Notice of Certain Events. In case the Company shall propose at
any time following the Distribution Date (a) to pay any dividend payable in
stock of any class to the holders of Preferred Stock or to make any other
distribution to the holders of Preferred Stock (other than a regular periodic
cash dividend), or (b) to offer to the holders of Preferred Stock rights or
warrants to subscribe for or to purchase any additional shares of Preferred
Stock or shares of stock of any class or any other securities, rights or
options, or (c) to effect any reclassification of Preferred Stock (other than a
reclassification involving only the subdivision of outstanding Preferred Stock),
or (d) 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 or more transactions,
of more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to, any other Person or Persons, or (e) to
effect the liquidation, dissolution or winding up of the Company, then, in each
such case, the Company shall give to the Rights Agent and to each holder of a
Right, in accordance with Section 26, a notice of such proposed action, which
shall specify the record date for the purposes of such stock dividend,
distribution of rights or Rights, or the date on which such reclassification,
consolidation, merger, sale, transfer, liquidation, dissolution, or winding up
is to take place and the date of participation therein by the holders of the
Preferred Stock, if any such date is to be fixed, and such notice shall be so
given in the case of any action covered by clause (a) or (b) above at least
twenty (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 twenty (20) days prior to the date of the taking of such
proposed action or the date of participation therein by the holders of the
Preferred Stock, whichever shall be the earlier.

     In case a Section 11(a)(ii) Event shall occur, then, in any such case, the
Company shall as soon as practicable thereafter give to the Rights Agent and to
each holder of a Right, to the extent feasible and in accordance with Section
26, 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) and
all references in the preceding paragraph to Preferred Stock shall be deemed to
thereaf-

                                      -48-


ter refer to Common Stock and/or other securities, as the case may be.

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

                  Attention:   General Counsel

     Section 27. Supplements and Amendments. Prior to the earlier of the
Distribution Date and the Shares Acquisition Date and subject to the ultimate
sentence of this Section 27, the Company may from time to time supplement or
amend this Agreement without the approval of any holders of Right Certificates.
From and after the earlier of the Distribution Date and the Shares Acquisition
Date, and subject to the ultimate sentence of this Section 27, the Company may
from time to time 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 


<PAGE>
                                      -49-


herein which may be defective or inconsistent with any other provisions herein,
or (iii) to lengthen the time period during which the Rights may be redeemed
following the Shares Acquisition Date for up to an additional twenty days beyond
the time period set forth in Section 23(a), or (iv) to change or supplement the
provisions hereunder 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). 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, if required by the Rights
Agent, an opinion of counsel, the Rights Agent shall execute such supplement or
amendment unless the Rights Agent shall have determined in good faith that such
supplement or amendment would adversely affect its interests under this
Agreement; provided, however, that anything herein to the contrary
notwithstanding, the Rights Agent shall not be obligated to enter into any
amendment or supplement that changes or increases the Rights Agent's duties,
liabilities or obligations. Notwithstanding anything in this Agreement to the
contrary, no supplement or amendment shall be made on or after the earlier of
the Distribution Date and the Shares Acquisition Date which changes the
Redemption Price, the Final Expiration Date, the Purchase Price or the number of
shares of Preferred Stock for which a Right is then exercisable.

     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. For all
purposes of this Agreement, any calculation of the number of shares of Voting
Stock outstanding at any particular time, including for purposes of determining
the particular percentage of such outstanding shares of Voting Stock of which
any Person is the Beneficial Owner, shall be made in accordance with the
provisions of Rule 13d-3(d)(1)(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 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 ad-


<PAGE>
                                      -50-


visable 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 the purpose of
clause (ii) below, all omissions with respect to the foregoing) which are done
or made by the Board in good faith (which good faith may be assumed by the
Rights Agent), shall (i) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Right Certificates and all other Persons, and
(ii) not subject the Board to any liability to the holders of the Right
Certificates.

     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) 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, registered holders of the Common Stock).

     Section 31. Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable, the remainder of the 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;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the Close of Business on the
tenth day following the date of such determination by the Board of Directors,
which determination shall be communicated by the Company to the Rights Agent.

     Section 32. Governing Law. This Agreement 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 such State applicable to contracts to be made and performed
entirely within such State except that the rights, 


<PAGE>
                                      -51-


duties and obligations of the Rights Agent under this Agreement shall be
governed by the laws of the State of New York.

     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 but one and
the same instrument.

     Section 34. Descriptive Headings. Descriptive headings of the several
Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                                   ----------


          Certificate of Designation of Board of Directors Classifying
                 and Designating a Series of Preferred Stock as

                  Series A Junior Participating Preferred Stock
                           and Fixing Distribution and
                   Other Preferences and Rights of Such Series


                                   ----------


     Engelhard Corporation, a Delaware corporation, having its principal office
in the State of New Jersey in the City of Iselin (the "Company"), hereby
certifies that:

     Pursuant to authority conferred upon the Board of Directors by the Restated
Certificate of Incorporation ("Charter") and Bylaws of the Company, the Board of
Directors pursuant to resolutions adopted on October 1, 1998 (i) authorized the
creation and issuance of up to 200,000 shares of Series A Junior Participating
Preferred Stock which stock was previously authorized but not issued and (ii)
determined the voting powers, designations, preferences and relative,
participating, optional or other special rights, qualifications, limitations or
restrictions, and terms and conditions of redemption of the shares of such
series and the Dividend Rate payable on such series. Such voting powers,
designations, preferences and relative, participating, optional or other special
rights, qualifications, limitations or restrictions, and terms and conditions of
redemption, number of shares and Dividend Rate are as follows:

     Section 1. Number of Shares and Designation. This class of Preferred Stock
shall be designated the Series A Junior Participating Preferred Stock (the
"Series A Preferred Shares") and the number of shares which shall constitute
such series shall be 200,000 shares, no par value. Such number of shares may be
increased or decreased by resolution of the Board of Directors; provided, that
no decrease shall reduce the number of Series A Preferred Shares to a number
less than the number of shares then outstanding plus the number of shares
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Company convertible into Series A Preferred Shares.


<PAGE>


     Section 2. Dividend Rights. (1) Subject to the rights of holders of any
shares of any series of Preferred Stock (or any similar stock) ranking prior and
superior to the Series A Preferred Shares with respect to dividends, the holders
of Series A Preferred Shares shall be entitled prior to the payment of any
dividends on shares ranking junior to the Series A Preferred Shares to receive,
when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the first day
of February, May, August and November in each year (each such date being
referred to herein as a "Quarterly Dividend Payment Date"), commencing on the
first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Preferred Shares, 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, 1000 times the aggregate
per share amount of all cash dividends, and 1000 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, par value $1.00 per share, of
the Company (the "Common Stock") or a subdivision of the outstanding shares of
Common Stock (by reclassification or otherwise)) declared on the Common Stock
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first issuance
of any share or fraction of a share of Series A Preferred Shares. In the event
the Company shall at any time (i) declare or pay 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 Series A Preferred Shares
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.

     (2) The Company shall declare a dividend or distribution on the Series A
Preferred Shares as provided in subparagraph (1) 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, in the event no dividend or
distribution shall have been declared on the Common Stock during the period
between any Quarterly Dividend Payment Date and the next subsequent Quarterly
Dividend Payment Date, a dividend of $1.00 per share on the Series A Preferred
Shares shall nevertheless be payable on such subsequent Quarterly Dividend
Payment Date.



                                      A-2
<PAGE>

     (3) Dividends shall begin to accrue and be cumulative on outstanding Series
A Preferred Shares from the Quarterly Dividend Payment Date next preceding the
date of issue of such Series A Preferred Shares, unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of Series A Preferred Shares 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. Accrued but unpaid dividends shall not bear interest. Dividends paid on
the Series A Preferred Shares in an amount less than the total amount of such
dividends at the time accrued and payable on such shares shall be allocated pro
rata on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of holders of
Series A Preferred Shares entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

     Section 3. Liquidation. (1) Upon any liquidation, dissolution or winding up
of the Company, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Preferred Shares unless, prior thereto, the holders
of shares of Series A Preferred Shares shall have received $1.00 per share (the
"Series A Liquidation Preference"), plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment. Following the payment of the full amount of the Series A
Liquidation Preference, no additional distributions shall be made to the holders
of shares of Series A Preferred Shares unless, prior thereto, the holders of
shares of Common Stock shall have received an amount per share (the "Common
Adjustment") equal to the quotient obtained by dividing (i) the Series A
Liquidation Preference by (ii) 1000 (as appropriately adjusted as set forth in
subparagraph (3) below to reflect such events as stocks splits, stock dividends
and recapitalizations with respect to the Common Stock) (such number in clause
(ii), the "Adjustment Number"). Following the payment of the full amount of the
Series A Liquidation Preference and the Common Adjustment in respect of all
outstanding Series A Preferred Shares and shares of Common Stock, respectively,
holders of Series A Preferred Shares and holders of shares of Common Stock shall
receive their ratable and proportionate share of the remaining assets to be
distributed in the ratio of the Adjustment Number to 1 with respect to the
Series A Pre-



                                      A-3
<PAGE>

ferred Shares and Common Stock, on a per share basis, respectively.

     (2) In the event, however, that there are not sufficient assets available
to permit payment in full of the Series A Liquidation Preference and the
liquidation preferences of all other series of Preferred Stock, if any, which
rank on a parity with the Series A Preferred Shares, then such remaining assets
shall be distributed ratably to the holders of such parity shares in proportion
to their respective liquidation preferences. In the event, however, that there
are not sufficient assets available to permit payment in full of the Common
Adjustment, then such remaining assets shall be distributed ratably to the
holders of Common Stock.

     (3) In the event the Company shall at any time (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 Adjustment Number in effect
immediately prior to such event shall be adjusted by multiplying such Adjustment
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.

     Section 4. No Redemption. The Series A Preferred Shares shall not be
redeemable.

     Section 5. Voting Rights. The holders of Series A Preferred Shares shall
have the following voting rights:

     (1) Subject to the provision for adjustment hereinafter set forth, each
Series A Preferred Share shall entitle the holder thereof to 1000 votes on all
matters voted on at a meeting of the stockholders of the Company. In the event
the Company shall at any time (i) declare or pay any dividend on Common Stock
payable in shares of Common Stock, or (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
Series A Preferred Shares 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.

     (2) Except as otherwise provided herein or by law, the holders of Series A
Preferred Shares and the holders of 



                                      A-4
<PAGE>

shares of Common Stock and any other capital stock of the Company having general
voting rights shall vote together as one voting group on all matters submitted
to a vote of stockholders of the Company.

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

     Section 6. Certain Restrictions.

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

          (i) declare or pay dividends on, make any other distributions on, or
     redeem or purchase or otherwise acquire for consideration any shares of
     stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred Shares;

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

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

          (iv) purchase or otherwise acquire for consideration any shares of
     Series A Preferred Shares or any shares of stock ranking on a parity with
     the Series A Preferred Shares, except in accordance with a purchase offer
     made in writing or by publication (as determined by the Board of 



                                      A-5
<PAGE>

     Directors) to all holders of such shares upon such terms as the Board of
     Directors, after consideration of the respective annual dividend rates and
     other relative rights and preferences of the respective series and classes,
     shall determine in good faith will result in fair and equitable treatment
     among the respective series or classes.

     (2) The Company shall not permit any subsidiary of the Company to purchase
or otherwise acquire for consideration any shares of stock of the Company unless
the Company could, under subparagraph (1) of this Section 6, purchase or
otherwise acquire such shares at such time and in such manner.

     Section 7. Reacquired Shares. Any Series A Preferred Shares purchased or
otherwise acquired by the Company in any manner whatsoever shall be retired and
cancelled promptly after the acquisition thereof. All such shares shall upon
their cancellation become authorized but unissued shares of Preferred Stock and
may be reissued as part of a new series of Preferred Stock to be created by
resolution or resolutions of the Board of Directors, subject to the conditions
and restrictions on issuance set forth herein or in the Charter.

     Section 8. Merger, Consolidation, etc. In case the Company shall enter into
any merger, consolidation, combination or other transaction in which the shares
of Common Stock are exchanged for or changed into other stock or securities,
cash and/or any other property, then in any such case each Series A Preferred
Share shall at the same time be similarly exchanged or changed into an amount
per share (subject to the provision for adjustment hereinafter set forth) equal
to 1000 times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged. In the event the Company shall at
any time (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 Series A Preferred Shares 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. Ranking. The Series A Preferred Shares shall rank, with respect
to the payment of dividends and distribution of assets, junior to all series of
any other class of the Company's Preferred Stock unless the terms of any such
series shall provide otherwise.



                                      A-6

     Section 10. Amendment. The Charter, including this Certificate of
Designation establishing the rights and preferences of the Series A Preferred
Shares, shall not be amended in any manner which would materially alter or
change the powers, preferences or special rights of the Series A Preferred
Shares so as to affect them adversely without the affirmative vote of the
holders of a majority of the outstanding shares of Series A Preferred Shares,
voting separately as one voting group.

     Section 11. Fractional Shares. Series A Preferred Shares may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Shares.

of Election to Purchase and related certificate duly executed, along with a
signature guarantee and such other and further documentation as the Rights Agent
may reasonably request. The number of Rights evidenced by this Right Certificate
(and the number of shares which may be purchased upon exercise thereof) set

(ii) a transferee of any such Acquiring Person, Associate or Affiliate who
becomes a transferee after the Acquiring Person becomes such, or (iii) under
certain circumstances specified in the Rights Agreement, a transferee of a

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 Triggering Event.

     As provided in the Rights Agreement, the Purchase Price and the number and
kind of shares of Preferred Stock (or, in certain circumstances, common stock
and/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, including Triggering Events.

     This Right Certificate is subject to all of the terms, covenants and
restrictions of the Rights Agreement, which terms, covenants and restrictions

this Certificate may be (i) redeemed by the Company at a redemption price of
$.001 per Right or (ii) exchanged by the Company in whole or in part for shares
of common stock or Preferred Stock.

any Right or Rights evidenced hereby (other than fractions which are integral
multiples of one one-thousandth of a share of Preferred Stock), but in lieu
thereof a cash payment will be made, as provided in the Rights Agreement.

     No holder of this Right Certificate shall be entitled to vote or receive
dividends or be deemed for any purpose the holder of the 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

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK


     The Board of Directors of Engelhard Corporation (the "Company") has
declared a dividend distribution of one Right for each outstanding share of
Common Stock, $1.00 par value (the "Common Stock"), of the Company. The
distribution is payable to holders of record on November 13, 1998 (the "Record
Date"). Each Right entitles the registered holder to purchase from the Company
one one-thousandth of a share of Series A Junior Participating Preferred Stock
(the "Preferred Stock"), at a price of $100 per one one-thousandth of a share
(the "Purchase Price"), subject to adjustment. The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights Agreement") between the
Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the
"Rights Agent").

Distribution Date; Transfer of Rights

     Until the earlier to occur of (i) ten calendar days following the date (the
"Shares Acquisition Date") of public announcement that a person or group of
affiliated or associated persons, subject to certain exceptions (an "Acquiring
Person") acquired, or obtained the right to acquire, beneficial ownership of
Common Stock or other voting securities ("Voting Stock") that have 15% or more
of the voting power of the outstanding shares of Voting Stock or (ii) ten
calendar days (or such later date as may be determined by action of the Board of
Directors prior to the time any person or group of affiliated persons becomes an
Acquiring Person) following the commencement or announcement of an intention to
make a tender offer or exchange offer the consummation of which would result in
such person or group acquiring, or obtaining the right to acquire, beneficial
ownership of Voting Stock having 15% or more of the voting power of the
outstanding shares of Voting Stock (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced, with respect to any of the
Company's Common Stock certificates outstanding as of the Record Date, by such
Common Stock certificates. The Rights Agreement provides that, until the
Distribution Date, the Rights will be transferred with and only with the
Company's Common Stock. Until the Distribution Date (or earlier redemption or
expiration of the Rights), new Common Stock certificates issued after the Record
Date upon transfer or new issuance of the Company's Common Stock will contain a
notation incorporating the Rights 



                                      C-1
<PAGE>

Agreement by reference. Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any of the Company's
Common Stock certificates outstanding as of the Record Date will also constitute
the transfer of the Rights associated with the Common 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 Company's Common Stock as of the close of business on
the Distribution Date and such separate Right Certificates alone will evidence
the Rights. The Rights Agreement provides that, as defined therein, the term
"Acquiring Person" shall not include the Minorco Entities or the Minorco
Designee as long as they are the Beneficial Owner of less than the Grandfathered
Percentage.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire at the close of business on October 1, 2008, unless earlier redeemed or
exchanged by the Company as described below.

Exercise of Rights for Common Stock of the Company

     In the event that a Person becomes an Acquiring Person, each holder of a
Right will thereafter have the right to receive, upon exercise, Common Stock
(or, in certain circumstances, cash, property or other securities of the
Company) having a value equal to two times the Purchase Price of the Right.
Notwithstanding any of the foregoing, following the occurrence of the event set
forth in this paragraph, all Rights that are, or (under certain circumstances
specified in the Rights Agreement) were, beneficially owned by any Acquiring
Person will be null and void.

Exercise of Rights for Shares of the Acquiring Company

     In the event that, at any time following the Shares Acquisition Date, (i)
the Company is acquired in a merger or other business combination transaction,
or (ii) 50% or more of the Company's assets or earning power is sold or
transferred, each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, common stock of the acquiring company having a value equal to two
times the Purchase Price of the Right.



                                      C-2
<PAGE>

Adjustments to Purchase Price

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

     With certain exceptions, no adjustment in the Purchase Price will be
required until the earlier of (i) three years from the date of the event giving
rise to such adjustment and (ii) the time at which cumulative adjustments
require an adjustment of at least 1% in such Purchase Price. No fractional
shares will be issued (other than fractional shares which are integral multiples
of one one-thousandth of a share of Preferred Stock) and, in lieu thereof, an
adjustment in cash will be made based on the market price of the Preferred Stock
on the last trading date prior to the date of exercise.

Redemption and Exchange of Rights

     At any time prior to 5:00 P.M. New York City time on the tenth calendar day
following the Shares Acquisition Date, the Company may redeem the Rights in
whole, but not in part, at a price of $.001 per Right (the "Redemption Price").
Immediately upon the action of the Board of Directors of the Company electing to
redeem the Rights, the Company shall make announcement thereof, and upon such
action, the right to exercise the Rights will terminate and the only right of
the holders of Rights will be to receive the Redemption Price.

     At any time after the occurrence of the event set forth under the heading
"Exercise of Rights for Common Stock of the Company" above, the Board of
Directors may exchange the Rights (other than Rights owned by the Acquiring
Person which shall have become void), in whole or in part, at an exchange ratio
of one share of Common Stock (or a fraction of a share of 



                                      C-3
<PAGE>

Preferred Stock having the same market value) per Right (subject to adjustment).

     Until a Right is exercised or exchanged, 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.

Terms of the Preferred Stock

     The Preferred Stock will rank junior to all other series of the Company's
preferred stock with respect to payment of dividends and as to distributions of
assets in liquidation. Each share of Preferred Stock will have a quarterly
dividend rate per share equal to the greater of $1.00 or 1000 times the per
share amount of any dividend (other than a dividend payable in shares of Common
Stock or a subdivision of the Common Stock) declared from time to time on the
Common Stock, subject to certain adjustments. The Preferred Stock will not be
redeemable. In the event of liquidation, the holders of the Preferred Stock will
be entitled to receive a preferred liquidation payment per share of $1.00 (plus
accrued and unpaid dividends) or, if greater, an amount equal to 1000 times the
payment to be made per share of Common Stock, subject to certain adjustments.
Generally, each share of Preferred Stock will vote together with the Common
Stock and any other series of cumulative preferred stock entitled to vote in
such manner and will be entitled to 1000 votes, subject to certain adjustments.
In the event of any merger, consolidation, combination or other transaction in
which shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or other property, each share of Preferred Stock will be
entitled to receive 1000 times the aggregate amount of stock, securities, cash
and/or other property, into which or for which each share of Common Stock is
changed or exchanged, subject to certain adjustments. The foregoing dividend,
voting and liquidation rights of the Preferred Stock are protected against
dilution in the event that additional shares of Common Stock are issued pursuant
to a stock split or stock dividend or distribution. Because of the nature of the
Preferred Stock's dividend, voting, liquidation and other rights, the value of
the one one-thousandth of a share of Preferred Stock purchasable with each Right
is intended to approximate the value of one share of Common Stock.

Amendments to Terms of the Rights

     Any of the provisions of the Rights Agreement may be amended by the Board
of Directors of the Company prior to the earlier of the Distribution Date or the
Shares Acquisition Date. After the earlier of the Distribution Date or the
Shares Acquisition Date, the provisions of the Rights Agreement may be amended
by the Board in order to cure any ambiguity, defect or inconsistency, or to make
changes which do not adversely affect the interests of holders of Rights
(excluding the interests of any Acquiring Person); provided, however, that no
supplement or amendment may be made after the earlier of the Distribution Date
or the Shares Acquisition Date which changes those provisions relating to the
principal economic terms of the Rights.

     A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an Exhibit to a Registration Statement on Form 8-A dated
October 29, 1998. A copy of the Rights Agreement is available free of charge
from the Company. This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
which is hereby incorporated herein by reference.
