Item 1. Description of Registrant's
        Securities to be Registered

        On June 15, 1998 the Board of Directors of IMS Health Incorporated (the
"Company") declared a dividend of one preferred share purchase right (a "Right")
for each outstanding share of common stock, par value $.01 per share of the
Company (the "Common Stock"). The dividend is payable on June 29, 1998 (the
"Record Date") to the stockholders of record on that date. Each Right entitles
the registered holder to purchase from the Company one one-thousandth of a share
of Series A Junior Participating Preferred Stock, par value $.01 per share (the
"Preferred Stock") of the Company at a price of $225 per one one-thousandth of a
share of Preferred Stock (as the same may be adjusted, the "Purchase Price"),
subject to adjustment. The description and terms of the Rights are set forth in
a Rights Agreement dated as of June 15, 1998 as the same may be amended from
time to time (the "Rights Agreement"), between the Company and First Chicago
Trust Company of New York as Rights Agent (the "Rights Agent").

         Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions an "Acquiring Person") have acquired beneficial ownership of
15% or more (20% or more in the case of an "Institutional Investor" as defined
in the Rights Agreement) of the outstanding shares of Common Stock or (ii) 10
business days (or such later date as may be determined by action of the Board of
Directors prior to such time as any person or group of affiliated persons
becomes an Acquiring Person) following the commencement of, or announcement of
an intention to make, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of 15% or more of
the outstanding shares of Common Stock (the earlier of such dates being called
the "Distribution Date"), the Rights will be evidenced by such Common Stock
certificate together with a copy of this Summary of Rights.

         The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights), the Rights will be transferred
with and only with the Common Stock. Until the Distribution Date (or earlier
redemption or expiration of the Rights), Common Stock certificates will contain
a notation incorporating the Rights Agreement by reference. Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any certificates for shares of Common Stock
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights, will also constitute the transfer of the Rights associated
with the shares of 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
Common Stock as of the close of business on the Distribution Date and such
separate Right Certificates alone will evidence the Rights.




<PAGE>


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

         The Purchase Price payable, and the number of shares of Preferred Stock
or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (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 or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-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 or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

         The Rights are also subject to adjustment in the event of a stock
dividend on the Common Stock payable in shares of Common Stock or subdivisions,
consolidations or combinations of the Common Stock occurring, in any such case,
prior to the Distribution Date.

         Shares of Preferred Stock purchasable upon exercise of the Rights will
not be redeemable. Each share of Preferred Stock will be entitled, when, as and
if declared, to a minimum preferential quarterly dividend payment of $10 per
share but will be entitled to an aggregate dividend of 1000 times the dividend
declared per share of Common Stock. In the event of liquidation, dissolution or
winding up of the Company, the holders of the Preferred Stock will be entitled
to a minimum preferential liquidation payment of $100 per share (plus any
accrued but unpaid dividends) but will be entitled to an aggregate payment of
1000 times the payment made per share of Common Stock. Each share of Preferred
Stock will have 1000 votes, voting together with the Common Stock. Finally, in
the event of any merger, consolidation or other transaction in which shares of
Common Stock are converted or exchanged, each share of Preferred Stock will be
entitled to receive 1000 times the amount received per share of Common Stock.
These rights are protected by customary antidilution provisions.

         Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of the one one-thousandth interest in a share of
Preferred Stock purchasable upon exercise of each Right should approximate the
value of one share of Common Stock.




<PAGE>


         In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right and payment
of the Purchase Price, that number of shares of Common Stock having a market
value of two times the Purchase Price.

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

         At any time after any person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the
outstanding shares of Common Stock or the occurrence of an event described in
the prior paragraph, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or a fractional share of Preferred Stock (or of a share of a similar class or
series of the Company's preferred stock having similar rights, preferences and
privileges) of equivalent value, per Right (subject to adjustment).

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

         At any time prior to the time an Acquiring Person becomes such, the
Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (the "Redemption Price"). The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.




<PAGE>


         For so long as the Rights are then redeemable, the Company may, except
with respect to the redemption price, amend the Rights in any manner. After the
Rights are no longer redeemable, the Company may, except with respect to the
redemption price, amend the Rights in any manner that does not adversely affect
the interests of holders of the Rights.

                                RIGHTS AGREEMENT

            Agreement, dated as of June 15, 1998 between IMS Health
Incorporated, a Delaware corporation (the "Company"), and First Chicago Trust
Company of New York (the "Rights Agent").

            The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each share of
Common Stock (as hereinafter defined) of the Company outstanding as of the close
of business (as defined below) on June 29, 1998 (the "Record Date") each Right
representing the right to purchase one-thousandth (subject to adjustment) of a
share of Preferred Stock (as hereinafter defined), upon the terms and subject to
the conditions herein set forth, and the Board of Directors has further
authorized and directed the issuance of one Right (subject to adjustment as
provided herein) with respect to each share of Common Stock that shall become
outstanding between the Record Date and the earliest of the Distribution Date,
the Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined); provided, however, that Rights may be issued with respect to shares of
Common Stock that shall become outstanding after the Distribution Date and prior
to the Redemption Date and the Final Expiration Date in accordance with Section
22.

            Accordingly, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:
<PAGE>
                                                                               2


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

            (a) "Acquiring Person" shall mean any Person (as such term is
      hereinafter defined) who or which shall be the Beneficial Owner (as such
      term is hereinafter defined) of 15% or more of the shares of Common Stock
      then outstanding (or, if an Institutional Investor (as hereinafter
      defined) 20% or more of the shares of Common Stock then outstanding), but
      shall not include an Exempt Person (as such term is hereinafter defined);
      provided, however, that if the Board of Directors of the Company
      determines in good faith that a Person who would otherwise be an
      "Acquiring Person" has become such inadvertently (including, without
      limitation, because (i) such Person was unaware that it beneficially owned
      a percentage of Common Stock that would otherwise cause such Person to be
      an "Acquiring Person" or (ii) such Person was aware of the extent of its
      Beneficial Ownership of Common Stock but had no actual knowledge of the
      consequences of such Beneficial Ownership under this Rights Agreement) and
      without any intention of changing or influencing control of the Company,
      and such Person, as promptly as practicable after being advised of such
      determination divested or divests himself or itself of Beneficial
      Ownership of a sufficient number of shares of Common Stock so that such
      Person would no longer be an Acquiring Person, then such Person shall not
      be deemed to be or to have become an "Acquiring Person" for any purposes
      of
<PAGE>
                                                                               3


      this Agreement. Notwithstanding the foregoing, (i) the sole stockholder of
      the Company at the time of the adoption of this Agreement will not be
      deemed an Acquiring Person for any purposes of this Agreement prior to the
      distribution by such Person of the Company's outstanding Common Stock to
      the stockholders of such Person and (ii) no Person shall become an
      "Acquiring Person" as the result of an acquisition of shares of Common
      Stock by the Company which, by reducing the number of shares outstanding,
      increases the proportionate number of shares beneficially owned by such
      Person to 15% or more (20% or more in the case of an Institutional
      Investor) of the shares of Common Stock then outstanding, provided,
      however, that if a Person shall become the Beneficial Owner of 15% or more
      (20% or more in the case of an Institutional Investor) of the shares of
      Common Stock then outstanding by reason of such share acquisitions by the
      Company and thereafter becomes the Beneficial Owner of any additional
      shares of Common Stock (other than pursuant to a dividend or distribution
      paid or made by the Company on the outstanding Common Stock in shares of
      Common Stock or pursuant to a split or subdivision of the outstanding
      Common Stock), then such Person shall be deemed to be an "Acquiring
      Person" unless upon the consummation of the acquisition of such additional
      shares of Common Stock such Person does not own 15% or more (20% or more
      in the case of an Institutional Investor) of the shares of Common Stock
      then outstanding. For all purposes of this Agreement, any calculation of
      the

      number of shares of Common Stock outstanding at any particular time,
      including for purposes of determining the particular percentage of such
      outstanding shares of Common Stock of which any Person is the Beneficial
      Owner, shall be made in accordance with the last sentence of Rule 13d-
      3(d)(1)(i) 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.

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

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

                  (i) which such Person or any of such Person's Affiliates or
            Associates is deemed to beneficially own, directly or indirectly
            within the meaning of Rule 13d-3 of the General Rules and
            Regulations under the Exchange Act as in effect on the date of this
            Agreement;

                  (ii) which such Person or any of such Person's Affiliates or
            Associates has (A) the right to acquire (whether such right is
            exercisable immediately or only after the passage of time) pursuant
            to any agreement, arrangement or understanding (other than customary
            agreements with and between underwriters and selling

                                                                               5

            securities), or upon the exercise of conversion rights, exchange
            rights, rights, warrants or options, or otherwise; provided,

            This certificate also evidences and entitles the holder hereof to
            certain rights as set forth in a Rights Agreement between IMS Health
            Incorporated and First Chicago Trust Company of New York, dated as
            of June 15, 1998 as the same may be amended from time to time (the
            "Rights Agreement"), the terms of which are hereby incorporated
            herein by reference and a copy of which is on file at the principal
            executive offices of IMS Health Incorporated. 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. IMS Health Incorporated will mail to
            the holder of this certificate a copy of the Rights Agreement
            without charge after receipt of a written request therefor. Under
            certain circumstances, as set forth in the Rights Agreement, Rights
            owned by or transferred to any Person who becomes an Acquiring
            Person (as defined in the Rights Agreement) and certain transferees
            thereof will become null and void and will no longer be
            transferable.
    

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Stock represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Stock represented thereby. In the event that the Company purchases or
otherwise acquires any Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such Common Stock shall be deemed
cancelled and retired so that the Company shall not be entitled

to exercise any Rights associated with the Common Stock which are no longer
outstanding.

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

            Section 4. Form of Right Certificates. The Right Certificates (and
the forms of election to purchase shares and of assignment to be printed on the
reverse thereof) shall be substantially in the form set forth in Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of the New York
Stock Exchange or of any other stock exchange or automated quotation system on
which the Rights may from time to time be listed, or to conform to usage.
Subject to the provisions of Sections 11, 13 and 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such number of one
one-thousandths of a share of Preferred Stock 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 one one-thousandths of a share of
Preferred Stock and the Purchase Price shall be subject to adjustment as

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

Subject to the provisions of Sections 7(e), 11(a)(ii) and 14 hereof, at any time
after the close of business on the Distribution Date, and prior to the close of
business on the earlier of the Redemption Date or the Final Expiration Date, any
Right Certificate or Right Certificates may be transferred, split up, combined
or exchanged for another Right Certificate or Right Certificates, entitling the
registered holder to purchase a like number of one one-thousandths of a share of
Preferred Stock as the Right Certificate or Right Certificates surrendered then
entitled such holder to purchase. Any registered holder desiring to transfer,
split up, combine or exchange any Right Certificate or Right Certificates shall
make such request in writing delivered to the Rights Agent, and shall surrender
the Right Certificate or Right Certificates to be transferred, split up,
combined or exchanged at the office or agency of the Rights Agent designated for
such purpose. Thereupon the Rights Agent shall countersign and deliver to the
Person entitled thereto a Right Certificate or Right Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax

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

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

exercisable on the Distribution Date, and thereafter the registered holder of
any Right Certificate may, subject to Section 11(a)(ii) hereof and except as

a Right shall be subject to adjustment from time to time as provided in Sections
11 and 13 hereof and shall be payable in lawful money of the United States of
America in accordance with paragraph (c) of this Section 7.

            (c) Except as otherwise provided herein, upon receipt of a Right

            (d) Except as otherwise provided herein, in case the registered
holder of any Right Certificate shall exercise less than all the Rights

time that a Person becomes an Acquiring Person, shares of Common Stock and other
securities) issuable upon the exercise of Rights may be listed or admitted to
trading on the New York Stock Exchange or listed on any other national
securities exchange or quotation system, the Company shall use its best efforts
to cause, from and after such time as the Rights become exercisable, all shares
reserved for such issuance to be listed or admitted to trading on the New York
Stock Exchange or listed on any other exchange or quotation system upon official
notice of issuance upon such exercise.

            (c) From and after such time as the Rights become exercisable, the
Company shall use its best efforts, if then necessary to permit the issuance of
shares of Preferred Stock (and following the time that a Person first becomes an
Acquiring Person, shares of Common Stock and other securities) upon the exercise
of Rights, to register and qualify such shares of Preferred Stock (and following

becomes an Acquiring Person, shares of Common Stock and other securities) under
the Securities Act and any applicable state securities or "Blue Sky" laws (to
the extent exemptions therefrom are not available), cause such registration
statement and qualifications to become effective as soon as possible after such
filing and keep such registration and qualifications effective until the earlier
of the date as of which the Rights are no longer exercisable for such securities
and the Final Expiration Date. The Company may temporarily suspend, for a period
of time not to exceed 90 days, the exercisability of the Rights in order to
prepare and file a registration statement under the Securities Act and permit it
to become effective. Upon any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement at such time as the suspension is no
longer in effect. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction unless the
requisite qualification in such jurisdiction shall have been obtained and until
a registration statement under the Securities Act (if required) shall have been
declared effective.

            (d) The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all shares of Preferred Stock (and,
following the time that a Person becomes an Acquiring Person, shares of Common
Stock and other securities) delivered upon exercise of Rights shall, at the time
of delivery of the certificates therefor (subject to payment of the Purchase

                                                                              22


Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

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

            Section 10. Preferred Stock Record Date. Each Person in whose name
any certificate for Preferred Stock is issued upon the exercise of Rights shall
for all purposes be deemed to have become the holder of record of the shares of
Preferred Stock represented thereby on, and such certificate shall be dated, the
date upon which the Right Certificate evidencing such Rights was

                                                                              23


duly surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Stock 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 transfer books of the Company are open. Prior to
the exercise of the Rights evidenced thereby, the holder of a Right Certificate
shall not be entitled to any rights of a holder of Preferred Stock for which the
Rights shall be exercisable, including, without limitation, the right to vote or
to receive dividends or other distributions, 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 and
Number of Rights. The Purchase Price, the number of shares of Preferred Stock or
other securities or property purchasable upon exercise of 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 Preferred Stock, (B) subdivide the outstanding
            Preferred Stock, (C) combine the outstanding Preferred Stock into a
            smaller number of Preferred Stock or (D) issue any shares of its
            capital stock in a reclassification of
<PAGE>
                                                                              24


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

                  (ii) Subject to Section 24 of this Agreement, in the event
            that any Person becomes an Acquiring Person, then (A) the Purchase
            Price shall be adjusted to be the Purchase Price in effect
            immediately prior to such
<PAGE>
                                                                              25


            Person becoming an Acquiring Person multiplied by the number of one
            one-thousandths of a share of Preferred Stock for which a Right was
            exercisable immediately prior to such Person becoming an Acquiring
            Person, whether or not such Right was then exercisable, and (B) each
            holder of a Right, except as otherwise provided in this Section
            11(a)(ii) and Subsection 11(a)(iii), hereof, shall thereafter have
            the right to receive, upon exercise at a price equal to the Purchase
            Price (as so adjusted), in accordance with the terms of this
            Agreement and in lieu of shares of Preferred Stock, such number of
            shares of Common Stock (or at the option of the Company, such number
            of one one-thousandths of shares of Preferred Stock) as shall equal
            the result obtained by (x) multiplying the then current Purchase
            Price by the number of one one-thousandths of a share of Preferred
            Stock for which a Right is then exercisable and dividing that
            product by (y) 50% of the then current per share market price of the
            Company's Common Stock (determined pursuant to Section 11(d) hereof)
            on the date such Person became an Acquiring Person; provided,
            however, that the Purchase Price and the number of shares of Common
            Stock so receivable upon exercise of a Right shall thereafter be
            subject to further adjustment as appropriate in accordance with
            Section 11(f) hereof. Notwithstanding anything in this Agreement to
            the contrary, however, from and after the

            time (the "invalidation time") when any Person first becomes an
            Acquiring Person, any Rights that are beneficially owned by (x) any
            Acquiring Person (or any Affiliate or Associate of any Acquiring
            Person), (y) a transferee of any Acquiring Person (or any such
            Affiliate or Associate) who becomes a transferee after the
            invalidation time or (z) a transferee of any Acquiring Person (or
            any such Affiliate or Associate) who became a transferee prior to or
            concurrently with the invalidation time pursuant to either (I) a
            transfer from the Acquiring Person to holders of its equity
            securities or to any Person with whom it has any continuing
            agreement, arrangement or understanding regarding the transferred
            Rights or (II) a transfer which the Board of Directors has
            determined is part of a plan, arrangement or understanding which has
            the purpose or effect of avoiding the provisions of this paragraph,
            and subsequent transferees of such Persons, shall be void without
            any further action and any holder of such Rights shall thereafter
            have no rights whatsoever with respect to such Rights under any
            provision of this Agreement. The Company shall use all reasonable
            efforts to ensure that the provisions of this Section 11(a)(ii) are
            complied with, but shall have no liability to any holder of Right
            Certificates or other Person as a result of its failure to make any
            determinations with respect to an Acquiring Person or
<PAGE>
                                                                              27


            its Affiliates, Associates or transferees hereunder. From and after
            the invalidation time, no Right Certificate shall be issued pursuant
            to Section 3 or Section 6 hereof that represents Rights that are or
            have become void pursuant to the provisions of this paragraph, and
            any Right Certificate delivered to the Rights Agent that represents
            Rights that are or have become void pursuant to the provisions of
            this paragraph shall be cancelled. From and after the occurrence of
            an event specified in Section 13(a) hereof, any Rights that
            theretofore have not been exercised pursuant to this Section
            11(a)(ii) shall thereafter be exercisable only in accordance with
            Section 13 and not pursuant to this Section 11(a)(ii).

                  (iii) The Company may at its option substitute for a share of
            Common Stock issuable upon the exercise of Rights in accordance with
            the foregoing subparagraph (ii) such number or fractions of shares
            of Preferred Stock having an aggregate current market value equal to
            the current per share market price of a share of Common Stock. In
            the event that there shall not be sufficient shares of Common Stock
            issued but not outstanding or authorized but unissued to permit the
            exercise in full of the Rights in accordance with the foregoing
            subparagraph (ii), the Board of Directors shall, to the extent
            permitted by applicable law and any material agreements then in
            effect to which the Company is a
<PAGE>
                                                                              28


            party (A) determine the excess of (1) the value of the shares of
            Common Stock issuable upon the exercise of a Right in accordance
            with the foregoing subparagraph (ii) (the "Current Value") over (2)
            the then current Purchase Price multiplied by the number of one
            one-thousandths of shares of Preferred Stock for which a Right was
            exercisable immediately prior to the time that the Acquiring Person
            became such (such excess, the "Spread"), and (B) with respect to
            each Right (other than Rights which have become void pursuant to
            Section 11(a)(ii)), make adequate provision to substitute for the
            shares of Common Stock issuable in accordance with subparagraph (ii)
            upon exercise of the Right and payment of the applicable Purchase
            Price, (1) cash, (2) a reduction in the Purchase Price, (3) shares
            of Preferred Stock or other equity securities of the Company
            (including, without limitation, shares or fractions of shares of
            preferred stock which, by virtue of having dividend, voting and
            liquidation rights substantially comparable to those of the shares
            of Common Stock, are deemed in good faith by the Board of Directors
            to have substantially the same value as the shares of Common Stock
            (such shares of preferred stock and shares or fractions of shares of
            preferred stock are hereinafter referred to as "Common Stock
            equivalents"), (4) debt securities of the Company, (5) other assets,
            or (6) any combination of the foregoing,

                                                                              29


            having a value which, when added to the value of the shares of
            Common Stock actually issued upon exercise of such Right, shall have
            an aggregate value equal to the Current Value (less the amount of
            any reduction in the Purchase Price), where such aggregate value has
            been determined by the Board of Directors upon the advice of a
            nationally recognized investment banking firm selected in good faith
            by the Board of Directors; provided, however, if the Company shall
            not make adequate provision to deliver value pursuant to clause (B)
            above within thirty (30) days following the date that the Acquiring
            Person became such (the "Section 11(a)(ii) Trigger Date"), then the
            Company shall be obligated to deliver, to the extent permitted by
            applicable law and any material agreements then in effect to which
            the Company is a party, 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, such
            number or fractions of shares of Preferred Stock (to the extent
            available) and then, if necessary, cash, which shares and/or cash
            have an aggregate value equal to the Spread. If, upon the date any
            Person becomes an Acquiring Person, the Board of Directors 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
<PAGE>
                                                                              30


            Rights, then, if the Board of Directors so elects, 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 stockholder
            approval for the authorization of such additional shares (such
            thirty (30) day period, as it may be extended, is herein called the
            "Substitution Period"). To the extent that the Company determines
            that some action need be taken pursuant to the second and/or third
            sentence of this Section 11(a)(iii), the Company (x) shall provide,
            subject to Section 11(a)(ii) hereof and the last sentence of this
            Section 11(a)(iii) 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 pursuant to such second
            sentence and to determine the value thereof. In the event of any
            such suspension, the Company shall issue a public announcement
            stating that the exercisability of the Rights has been temporarily
            suspended, as well as a public announcement at such time as the
            suspension is no longer in effect. For purposes of this Section
            11(a)(iii), the value of the shares of Common Stock shall be the
            current per share market price (as
<PAGE>
                                                                              31


            determined pursuant to Section 11(d)(i)) on the Section 11(a)(ii)
            Trigger Date and the per share or fractional value of any "Common
            Stock equivalent" shall be deemed to equal the current per share
            market price of the Common Stock. The Board of Directors of the
            Company may, but shall not be required to, establish procedures to
            allocate the right to receive shares of Common Stock upon the
            exercise of the Rights among holders of Rights pursuant to 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 shares having
      similar rights, privileges and preferences as the Preferred Stock
      ("equivalent preferred shares")) or securities convertible into Preferred
      Stock or equivalent preferred shares at a price per share of Preferred
      Stock or equivalent preferred shares (or having a conversion price per
      share, if a security convertible into shares of Preferred Stock or
      equivalent preferred shares) less than the then current per share market
      price of the Preferred Stock (determined pursuant to Section 11(d) hereof)
      on such record date, the Purchase Price to be in effect after such record
      date shall be determined by multiplying the Purchase Price in effect
      immediately prior to such record date by a fraction, the numerator of
      which shall be the number of shares of
<PAGE>
                                                                              32


      Preferred Stock and equivalent preferred shares outstanding on such record
      date plus the number of shares of Preferred Stock and equivalent preferred
      shares which the aggregate offering price of the total number of shares of
      Preferred Stock and/or equivalent preferred shares so to be offered
      (and/or the aggregate initial conversion price of the convertible
      securities so to be offered) would purchase at such current market price,
      and the denominator of which shall be the number of shares of Preferred
      Stock and equivalent preferred shares outstanding on such record date plus
      the number of additional shares of Preferred Stock and/or equivalent
      preferred shares to be offered for subscription or purchase (or into which
      the convertible securities so to be offered are initially convertible);
      provided, however, that in no event shall the consideration to be paid
      upon the exercise of one Right be less than the aggregate par value of the
      shares of capital stock of the Company issuable upon exercise of one
      Right. In case such subscription price may be paid in a consideration part
      or all of which shall be in a form other than cash, the value of such
      consideration shall be as determined in good faith by the Board of
      Directors of the Company, whose determination shall be described in a
      statement filed with the Rights Agent. Shares of Preferred Stock and
      equivalent preferred shares owned by or held for the account of the
      Company shall not be deemed outstanding for the purpose of any such
      computation. Such adjustment shall be made successively whenever such a
<PAGE>
                                                                              33


      record date is fixed; and in the event that such rights, options or
      warrants are not so issued, the Purchase Price shall be adjusted to be the
      Purchase Price which would then be in effect if such record date had not
      been fixed.

            (c) In case the Company shall fix a record date for the making of a
      distribution to all holders of the Preferred 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 quarterly cash dividend or a
      dividend payable in Preferred Stock) or subscription rights or warrants
      (excluding those referred to in Section 11(b) hereof), the Purchase Price
      to be in effect after such record date shall be determined by multiplying
      the Purchase Price in effect immediately prior to such record date by a
      fraction, the numerator of which shall be the then current per share
      market price of the Preferred Stock (determined pursuant to Section 11(d)
      hereof) 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 the denominator of which shall be such current per
      share market price (determined pursuant to Section 11(d) hereof) of the
      Preferred Stock; provided, however, that in
<PAGE>
                                                                              34


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

            (d) (i) Except as otherwise provided herein, for the purpose of any
      computation hereunder, the "current per share market price" of any
      security (a "Security" for the purpose of this Section 11(d)(i)) on any
      date shall be deemed to be the average of the daily closing prices per
      share of such Security for the 30 consecutive Trading Days (as such term
      is hereinafter defined) immediately prior to such date; provided, however,
      that in the event that the current per share market price of the Security
      is determined during a period following the announcement by the issuer of
      such Security of (A) a dividend or distribution on such Security payable
      in shares of such Security or securities convertible into such shares, or
      (B) any subdivision, combination or reclassification of such Security, and
      prior to the expiration of 30 Trading Days after the ex-dividend date for
      such dividend or distribution, or the record date for such subdivision,
      combination or reclassification, then, and in each such case, the current
      per share market price shall be
<PAGE>
                                                                              35


      appropriately adjusted to reflect the current market price per share
      equivalent of such Security. The closing price for each day shall be the
      last sale price, regular way, or, in case no such sale takes place on such
      day, the average of the closing bid and asked prices, regular way, in
      either case as reported by the principal consolidated transaction
      reporting system with respect to securities listed or admitted to trading
      on the New York Stock Exchange or, if the Security is not listed or
      admitted to trading on the New York Stock Exchange, as reported in the
      principal consolidated transaction reporting system with respect to
      securities listed on the principal national securities exchange on which
      the Security is listed or admitted to trading or, if the Security is not
      listed or admitted to trading on any national securities exchange, the
      last quoted price or, if not so quoted, the average of the high bid and
      low asked prices in the over-the-counter market, as reported by NASDAQ or
      such other system then in use, or, if on any such date the Security is not
      quoted by any such organization, the average of the closing bid and asked
      prices as furnished by a professional market maker making a market in the
      Security selected by the Board of Directors of the Company. The term
      "Trading Day" shall mean a day on which the principal national securities
      exchange on which the Security is listed or admitted to trading is open
      for the transaction of business or, if the Security is not
<PAGE>
                                                                              36


      listed or admitted to trading on any national securities exchange, a
      Business Day.

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

            (e) No adjustment in the Purchase Price shall be required unless
      such adjustment would require an increase or decrease of at least 1% in
      the Purchase Price; provided, however, that any adjustments which by
      reason of this Section 11(e) are not required to be made shall be carried
      forward and taken into account in any subsequent adjustment. All
      calculations under this Section 11 shall be made to the nearest cent or to
      the nearest one ten-thousandth of a share
<PAGE>
                                                                              37


      of Preferred Stock or share of Common Stock or other share or security as
      the case may be. Notwithstanding the first sentence of this Section 11(e),
      any adjustment required by this Section 11 shall be made no later than the
      earlier of (i) three years from the date of the transaction which requires
      such adjustment or (ii) the date of the expiration of the right to
      exercise any Rights.

            (f) If as a result of an adjustment made pursuant to Section 11(a)
      hereof, the holder of any Right thereafter exercised shall become entitled
      to receive any shares of capital stock of the Company other than the
      Preferred Stock, thereafter the Purchase Price and the number of such
      other shares so receivable upon exercise of a Right shall be subject to
      adjustment from time to time in a manner and on terms as nearly equivalent
      as practicable to the provisions with respect to the Preferred Stock
      contained in Sections 11(a), 11(b), 11(c), 11(e), 11(h), 11(i) and 11(m)
      and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to
      the Preferred Stock shall apply on like terms to any such other shares.

            (g) All Rights originally issued by the Company subsequent to any
      adjustment made to the Purchase Price hereunder shall evidence the right
      to purchase, at the adjusted Purchase Price, the number of 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.
<PAGE>
                                                                              38


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

            (i) The Company may elect on or after the date of any adjustment of
      the Purchase Price to adjust the number of Rights, in substitution for any
      adjustment in the number of one one-thousandths of a share of Preferred
      Stock purchasable upon the exercise of a Right. Each of the Rights
      outstanding after such adjustment of the number of Rights shall be
      exercisable for the number of one one-thousandths of a share of Preferred
      Stock for which a Right was exercisable immediately prior to such
      adjustment. Each Right held of record prior to such adjustment of the
      number of Rights shall become that number of Rights (calculated to the
      nearest one ten-thousandth) obtained by
<PAGE>
                                                                              39


      dividing the Purchase Price in effect immediately prior to adjustment of
      the Purchase Price by the Purchase Price in effect immediately after
      adjustment of the Purchase Price. The Company shall make a public
      announcement of its election to adjust the number of Rights, indicating
      the record date for the adjustment, and, if known at the time, the amount
      of the adjustment to be made. This record date may be the date on which
      the Purchase Price is adjusted or any day thereafter, but, if the 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 may, as promptly as practicable, cause to be
      distributed to holders of record of Right Certificates on such record date
      Right Certificates evidencing, subject to Section 14 hereof, the
      additional Rights to which such holders shall be entitled as a result of
      such adjustment, or, at the option of the Company, shall cause to be
      distributed to such holders of record in substitution and replacement for
      the Right Certificates held by such holders prior to the date of
      adjustment, and upon surrender thereof, if required by the Company, new
      Right Certificates evidencing all the Rights to which such holders shall
      be entitled after such adjustment. Right Certificates so to be distributed
      shall be issued, executed and countersigned in the manner provided for
      herein and shall be registered in the names of the holders of record of
      Right
<PAGE>
                                                                              40


      Certificates on the record date specified in the public announcement.

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

            (k) Before taking any action that would cause an adjustment reducing
      the Purchase Price below the then par value, if any, of the Preferred
      Stock or other shares of capital 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 shares of Preferred Stock
      or other such shares at such adjusted Purchase Price.

            (l) In any case in which this Section 11 shall require that an
      adjustment in the Purchase Price be made effective as of a record date for
      a specified event, the Company may elect to defer until the occurrence of
      such event the issuing to the holder of any Right exercised after such
      record date of the Preferred Stock and other capital stock or securities
      of the Company, if any, issuable upon such exercise over and above the
      Preferred Stock and other
<PAGE>
                                                                              41


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

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

            (n) Anything in this Agreement to the contrary notwithstanding, in
      the event that at any time after the date of this Agreement and prior to
      the Distribution Date, the Company shall (i) declare or pay any dividend
      on the
<PAGE>
                                                                              42


      Common Stock payable in Common Stock or (ii) effect a subdivision,
      combination or consolidation of the Common Stock (by reclassification or
      otherwise than by payment of a dividend payable in Common Stock) into a
      greater or lesser number of Common Stock, then in any such case, the
      number of Rights associated with each share of Common Stock then
      outstanding, or issued or delivered thereafter, shall be proportionately
      adjusted so that the number of Rights thereafter associated with each
      share of Common Stock following any such event shall equal the result
      obtained by multiplying the number of Rights associated with each share of
      Common Stock immediately prior to such event by a fraction the numerator
      of which shall be the total number of shares of Common Stock outstanding
      immediately prior to the occurrence of the event and the denominator of
      which shall be the total number of shares of Common Stock outstanding
      immediately following the occurrence of such event.

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

            Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 or 13 hereof,
the Company shall promptly (a) prepare a

                                                                              43


certificate setting forth such adjustment, and a brief statement of the facts
accounting for such adjustment, (b) file with the Rights Agent and with each
transfer agent for the Common Stock or the Preferred Stock a copy of such
certificate and (c) mail a brief summary thereof to each holder of a Right
Certificate in accordance with Section 25 hereof (if so required under Section
25 hereof). The Rights Agent shall be fully protected in relying on any such
certificate and on any adjustment therein contained and shall not be deemed to
have knowledge of any such adjustment unless and until it shall have received
such certificate.

            Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earnings Power. (a) In the event, directly or indirectly, at any time after any
Person has become an Acquiring Person, (i) the Company shall merge with and into
any other Person, (ii) any Person shall consolidate with the Company, or any
Person shall merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Stock shall be changed into or exchanged for
stock or other securities of any other Person (or of the Company) or cash or any
other property, or (iii) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person (other than the Company or one or more of its wholly-owned
Subsidiaries), then upon the first occurrence of

                                                                              44


such event, proper provision shall be made so that: (A) each holder of record of
a Right (other than Rights which have become void pursuant to Section 11(a)(ii))
shall thereafter have the right to receive, upon the exercise thereof at a price
equal to the then current Purchase Price multiplied by the number of one
one-thousandths of a share of Preferred Stock for which a Right was exercisable
(whether or not such Right was then exercisable) immediately prior to the time
that any Person first became an Acquiring Person (each as subsequently adjusted
thereafter pursuant to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)),
in accordance with the terms of this Agreement and in lieu of Preferred Stock,
such number of validly issued, fully paid and non-assessable and freely
tradeable shares of Common Stock of the Principal Party (as defined herein) not
subject to any liens, encumbrances, rights of first refusal or other adverse
claims, as shall be equal to the result obtained by (1) multiplying the then
current Purchase Price by the number of one one-thousandths of a share of
Preferred Stock for which a Right was exercisable immediately prior to the time
that any Person first became an Acquiring Person (as subsequently adjusted
thereafter pursuant to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m))
and (2) dividing that product by 50% of the then current per share market price
of the Common Stock of such Principal Party (determined pursuant to Section
11(d)(i) hereof) on the date of consummation of such consolidation, merger, sale
or transfer; provided that the Purchase Price and the number of shares of Common
Stock of such Principal Party issuable upon
<PAGE>
                                                                              45


exercise of each Right shall be further adjusted as provided in Section 11(f) of
this Agreement to reflect any events occurring in respect of such Principal
Party after the date of the such consolidation, merger, sale or transfer; (B)
such Principal Party shall thereafter be liable for, and shall assume, by virtue
of such consolidation, merger, sale or transfer, all the obligations and duties
of the Company pursuant to this Agreement; (C) the term "Company" shall
thereafter be deemed to refer to such Principal Party; and (D) such Principal
Party shall take such steps (including, but not limited to, the reservation of a
sufficient number of its shares of Common Stock in accordance with Section 9
hereof) in connection with such consummation of any such transaction as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to the shares of its Common Stock
thereafter deliverable upon the exercise of the Rights; provided that, upon the
subsequent occurrence of any consolidation, merger, sale or transfer of assets
or other extraordinary transaction in respect of such Principal Party, each
holder of a Right shall thereupon be entitled to receive, upon exercise of a
Right and payment of the Purchase Price as provided in this Section 13(a), such
cash, shares, rights, warrants and other property which such holder would have
been entitled to receive had such holder, at the time of such transaction, owned
the Common Stock of the Principal Party receivable upon the exercise of a Right
pursuant to this Section 13(a), and such Principal Party shall take such steps
(including, but not limited to,
<PAGE>
                                                                              46


reservation of shares of stock) as may be necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property.

            (b) "Principal Party" shall mean

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

                  (ii) in the case of any transaction described in (iii) of the
      first sentence in Section 13(a) hereof, the Person that is the party
      receiving the greatest portion of the assets or earning power transferred
      pursuant to such transaction or transactions, or, if each Person that is a
      party to such transaction or transactions receives the same
<PAGE>
                                                                              47


      portion of the assets or earning power so transferred or if the Person
      receiving the greatest portion of the assets or earning power cannot be
      determined, whichever of such Persons as is the issuer of Common Stock
      having the greatest aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Stock of such Person is not at such time or has
not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Stock of which is and has been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
and the Common Stocks of all of such persons have been so registered, the term
"Principal Party" shall refer to whichever of such Persons is the issuer of
Common Stock having the greatest aggregate market value of shares outstanding,
or (3) if such Person is owned, directly or indirectly, by a joint venture
formed by two or more Persons that are not owned, directly or indirectly, by the
same Person, the rules set forth in clauses (1) and (2) above shall apply to
each of the owners having an interest in the venture as if the Person owned by
the joint venture was a Subsidiary of both or all of such joint venturers, and
the Principal Party in each such case shall bear the obligations set forth in
this Section 13 in the same ratio as its interest in such Person bears to the
total of such interests.

                                                                              48


            (c) The Company shall not consummate any consolidation, merger, sale
or transfer referred to in Section 13(a) hereof unless prior thereto the Company
and the Principal Party involved therein shall have executed and delivered to
the Rights Agent an agreement confirming that the requirements of Sections 13(a)
and (b) hereof shall promptly be performed in accordance with their terms and
that such consolidation, merger, sale or transfer of assets shall not result in
a default by the Principal Party under this Agreement as the same shall have
been assumed by the Principal Party pursuant to Sections 13(a) and (b) hereof
and providing that, as soon as practicable after executing such agreement
pursuant to this Section 13, the Principal Party will:

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

                  (ii) use its best efforts, if the Common Stock of the
      Principal Party shall be listed or admitted to trading on the New York
      Stock Exchange or on another national securities exchange, to list or
      admit to trading (or
<PAGE>
                                                                              49


      continue the listing of) the Rights and the securities purchasable upon
      exercise of the Rights on the New York Stock Exchange or such securities
      exchange, or, if the Common Stock of the Principal Party shall not be
      listed or admitted to trading on the New York Stock Exchange or a national
      securities exchange, to cause the Rights and the securities receivable
      upon exercise of the Rights to be reported by such other system then in
      use;

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

                  (iv) obtain waivers of any rights of first refusal or
      preemptive rights in respect of the Common Stock of the Principal Party
      subject to purchase upon exercise of outstanding Rights.

            (d) In case the Principal Party has provision in any of its
authorized securities or in its certificate of incorporation or by-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue (other than to holders of
Rights pursuant to this Section 13), in connection with, or as a consequence of,
the consummation of a transaction referred to in this Section 13, shares of
Common Stock of such Principal Party at less than the then current market price
per share thereof (determined pursuant to Section 11(d) hereof) or securities

Principal Party at less than such then current market price, or (ii) providing
for any special payment, tax or similar provision in connection with the
issuance of the Common Stock of such Principal Party pursuant to the provisions
of Section 13, then, in such event, the Company hereby agrees with each holder
of Rights that it shall not consummate any such transaction unless prior thereto
the Company and such Principal Party shall have executed and delivered to the
Rights Agent a supplemental agreement providing that the provision in question
of such Principal Party shall have been cancelled, waived or amended, or that
the authorized securities shall be redeemed, so that the applicable provision
will have no effect in connection with, or as a consequence of, the consummation
of the proposed transaction.

            (e) The Company covenants and agrees that it shall not, at any time
after a Person first becomes an Acquiring Person enter into any transaction of
the type contemplated by (i) - (iii) of Section 13(a) hereof if (x) at the time
of or immediately after such consolidation, merger, sale, transfer or other
transaction there are 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, (y)
prior to, simultaneously with or immediately after such consolidation, merger,
sale, transfer of other transaction, 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
or Associates or (z) the form or nature of organization of the Principal Party
would preclude or limit the exercisability of the Rights.

            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 (except prior to the Distribution
Date in accordance with Section 11(n) hereof). In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right. For the purposes of this Section 14(a), the current market value of a
whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable. The closing price for any day shall be the last sale price,
regular way, or, in case no such sale takes place on such day, the average of
the closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange or, if the Rights
are not listed or admitted to trading on the New York Stock Exchange, as
reported in the principal consolidated transaction reporting system with respect
to securities listed on the principal national securities exchange on which the
Rights are listed or

                                                                              52


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

            (b) The Company shall not be required to issue fractions of
Preferred 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 of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock). Interests in fractions of Preferred Stock in integral
multiples of one one-thousandth of a share of Preferred Stock may, at the
election of the Company, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Company and a depositary selected by it;
provided, that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the Preferred Stock represented by such
depositary receipts. In

                                                                              53


lieu of fractional shares of Preferred Stock that are not integral multiples of
one one-thousandth of a share of Preferred Stock, the Company shall pay to the
registered holders of Right Certificates at the time such Rights are exercised
as herein provided an amount in cash equal to the same fraction of the current
market value of one share of Preferred Stock. For the purposes of this Section
14(b), the current market value of a share of Preferred Stock shall be the
closing price of a share of Preferred Stock (as determined pursuant to Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

            (c) The Company shall not be required to issue fractions of shares
of Common Stock or to distribute certificates which evidence fractional shares
of Common Stock upon the exercise or exchange of Rights. 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 in an amount in cash equal to the same
fraction of the current market value of a whole share of Common Stock (as
determined in accordance with Section 14(a) hereof) for the Trading Day
immediately prior to the date of such exercise or exchange.

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

                                                                              54


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

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

                                                                              55


            (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 or agency of the Rights Agent designated for such purpose,
      duly endorsed or accompanied by a proper instrument of transfer; and

            (c) the Company and the Rights Agent may deem and treat the Person
      in whose name the Right Certificate (or, prior to the Distribution Date,
      the 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 Common Stock
      certificate made by anyone other than the Company or the Rights Agent) for
      all purposes whatsoever, and neither the Company nor the Rights Agent
      shall be affected by any notice to the contrary.

            Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Stock or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the
<PAGE>
                                                                              56


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 this Agreement), or to receive dividends or subscription rights, or
otherwise, until the Rights evidenced by such Right Certificate shall have been
exercised in accordance with the provisions hereof.

            Section 18. Concerning the Rights Agent. (a) The Company agrees to
pay to the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses and counsel fees and other disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability or expense, incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability arising therefrom, directly or
indirectly.

            (b) The Rights Agent shall be protected and shall incur no liability
for, or in respect of any action taken, suffered or omitted by it in connection
with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Stock or Common Stock or for other
<PAGE>
                                                                              57


securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

            Section 19. Merger or Consolidation or Change of Name of Rights
Agent. (a) Any corporation into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any corporation succeeding to the
stock transfer or corporate trust powers of the Rights Agent or any successor
Rights Agent, shall be the successor to the Rights Agent under this Agreement
without the execution or filing of any paper or any further act on the part of
any of the parties hereto; provided, that such corporation would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
hereof. In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement, any of the Right Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such Right
Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such
<PAGE>
                                                                              58


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

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

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

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

            (b) Whenever in the performance of its duties under this Agreement
      the Rights Agent shall deem it necessary or
<PAGE>
                                                                              59


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

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

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

            (e) The Rights Agent shall not be under any responsibility in
      respect of the validity of this Agreement or the execution and delivery
      hereof (except the due execution hereof by the Rights Agent) or in respect
      of the validity or execution of any Right Certificate (except its
<PAGE>
                                                                              60


      countersignature thereof); nor shall it be responsible for any breach by
      the Company of any covenant or condition contained in this Agreement or in
      any Right Certificate; nor shall it be responsible for any change in the
      exercisability of the Rights (including the Rights becoming void pursuant
      to Section 11(a)(ii) hereof) or any adjustment in the terms of the Rights
      (including the manner, method or amount thereof) provided for in Sections
      3, 11, 13, 23 and 24, or the ascertaining of the existence of facts that
      would require any such change or adjustment (except with respect to the
      exercise of Rights evidenced by Right Certificates after receipt of a
      certificate furnished pursuant to Section 12, describing such change or
      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 other securities to be issued pursuant to
      this Agreement or any Right Certificate or as to whether any shares of
      Preferred Stock or other securities will, when issued, be validly
      authorized and issued, fully paid and nonassessable.

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

            (g) The Rights Agent is hereby authorized and directed to accept
      instructions with respect to the performance of its duties hereunder from
      any person reasonably believed by the Rights Agent to be one of the
      Chairman of the Board of Directors, the President, the Chief Financial
      Officer or the Secretary of the Company, and to apply to such officers for
      advice or instructions in connection with its duties, and it shall not be
      liable for any action taken or suffered by it in good faith in accordance
      with instructions of any such officer or for any delay in acting while
      waiting for those instructions. Any application by the Rights Agent for
      written instructions from the Company may, at the option of the Rights
      Agent, set forth in writing any action proposed to be taken or omitted by
      the Rights Agent under this Agreement and the date on and/or after which
      such action shall be taken or such omission shall be effective. The Rights
      Agent shall not be liable for any action taken by, or omission of, the
      Rights Agent in accordance with a proposal included in any such
      application on or after the date specified in such application (which date
      shall not be less than five Business Days after the date any officer of
      the Company actually receives such application, unless any such officer
      shall have consented in writing to an earlier date) unless, prior to
      taking any such action (or the effective date in the case of an omission),
      the Rights Agent shall have received written instructions in response to
      such application specifying the action to be taken or omitted.
<PAGE>
                                                                              62


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

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

            (j) If, with respect to any Rights Certificate surrendered to the
      Rights Agent for exercise or transfer, the certificate contained in the
      form of assignment or the form of election to purchase set forth on the
      reverse thereof, as the case may be, has not been completed to certify the
      holder is not an Acquiring Person (or an Affiliate or Associate thereof),
      the Rights Agent shall not take any further action with respect to such
      requested
<PAGE>
                                                                              63


      exercise or transfer without first consulting with the Company.

            Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Stock or Preferred Stock by registered or certified
mail, and, following the Distribution Date, to the holders of the Right
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor Rights Agent upon 30 days' notice in writing, mailed to the Rights
Agent or successor Rights Agent, as the case may be, and to each transfer agent
of the Common Stock or Preferred Stock by registered or certified mail, and,
following the Distribution Date, to the holders of the Right Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights Agent or by the holder of a Right Certificate (who shall,
with such notice, submit his Right Certificate for inspection by the Company),
then the registered holder of any Right Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent, whether appointed by the Company or by such a court, shall be (A)
a corporation organized
<PAGE>
                                                                              64


and doing business under the laws of the United States or any State thereof,
which is authorized under such laws to exercise corporate trust or stock
transfer powers and is subject to supervision or examination by federal or state
authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $50 million or (B) an affiliate of a
corporation described in clause (A) of this sentence. After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the purpose. Not later than the effective date of any such appointment the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Stock or Preferred Stock, and, following
the Distribution Date, mail a notice thereof in writing to the registered
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

            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
<PAGE>
                                                                              65


Right Certificates evidencing Rights in such forms 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
Common Stock following the Distribution Date and prior to the earlier of the
Redemption Date and the Final Expiration Date, the Company may with respect to
shares of Common Stock so issued or sold pursuant to (i) the exercise of stock
options, (ii) under any employee plan or arrangement, (iii) upon the exercise,
conversion or exchange of securities, notes or debentures issued by the Company
or (iv) a contractual obligation of the Company in each case existing prior to
the Distribution Date, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale.

            Section 23. Redemption. (a) The Board of Directors of the Company
may, at any time prior to such time as any Person first becomes an Acquiring
Person, redeem all but not less than all the then outstanding Rights at a
redemption price of $.01 per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(the redemption price being hereinafter referred to as the "Redemption Price").
The redemption of the Rights may be made effective at such time, on such basis
and with such conditions as the Board of Directors in its sole discretion may
establish. The Company may, at its option, pay the Redemption Price in cash,
<PAGE>
                                                                              66


shares of Common Stock (based on the current market price of the Common Stock at
the time of redemption) or any other form of consideration deemed appropriate by
the Board of Directors.

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

                                                                              67


of the Company may, at its option, at any time after any Person first becomes an
Acquiring Person, exchange all or part of the then outstanding and exercisable
Rights (which shall not include Rights that have not become effective or that
have become void pursuant to the provisions of Section 11(a)(ii) 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 amount per Right being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time (1) after any Person (other than an Exempt Person), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of shares
of Common Stock aggregating 50% or more of the shares of Common Stock then
outstanding. From and after the occurrence of an event specified in Section
13(a) hereof, any Rights that theretofore have not been exchanged pursuant to
this Section 24(a) shall thereafter be exercisable only in accordance with
Section 13 and may not be exchanged pursuant to this Section 24(a). The exchange
of the Rights by the Board of Directors may be made effective at such time, on
such basis and with such conditions as the Board of Directors in its sole
discretion may establish.

            (b) Immediately upon the effectiveness of the action of the Board of
Directors of the Company ordering the exchange of any Rights pursuant to
paragraph (a) of this Section 24 and without any further action and without any
notice, the right to

                                                                              68


exercise such Rights shall terminate and the only right thereafter of a holder
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. The Company shall promptly give public notice of any such exchange;
provided, however, that the failure to give, or any defect in, such notice shall
not affect the validity of such exchange. The Company shall promptly mail a
notice of any such exchange to all of the holders of the Rights so exchanged at
their last addresses as they appear upon the registry books of the Rights Agent.
Any notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will
state the method by which the exchange of the shares of Common Stock for Rights
will be effected and, in the event of any partial exchange, the number of Rights
which will be exchanged. Any partial exchange shall be effected pro rata based
on the number of Rights (other than Rights which have become void pursuant to
the provisions of Section 11(a)(ii) hereof) held by each holder of Rights.

            (c) The Company may at its option and, in the event that there shall
not be sufficient shares of Common Stock issued but not outstanding or
authorized but unissued to permit an exchange of Rights as contemplated in
accordance with this Section 24, the Company shall substitute to the extent of
such insufficiency, for each share of Common Stock that would otherwise be
issuable upon exchange of a Right, a number of shares of Preferred Stock or
fraction thereof (or equivalent

                                                                              69


preferred shares as such term is defined in Section 11(b)) such that the current
per share market price (determined pursuant to Section 11(d) hereof) of one
share of Preferred Stock (or equivalent preferred share) multiplied by such
number or fraction is equal to the current per share market price of one share
of Common Stock (determined pursuant to Section 11(d) hereof) as of the date of
such exchange).

            Section 25. Notice of Certain Events. (a) In case the Company shall
at any time after the earlier of the Distribution Date or the Stock Acquisition
Date propose (i) to pay any dividend payable in stock of any class to the
holders of its Preferred Stock or to make any other distribution to the holders
of its Preferred Stock (other than a regular quarterly cash dividend), (ii) to
offer to the holders of its Preferred Stock rights or warrants to subscribe for
or to purchase any additional shares of Preferred Stock or shares of stock of
any class or any other securities, rights or options, (iii) to effect any
reclassification of its Preferred Stock (other than a reclassification involving
only the subdivision or combination of outstanding Preferred Stock), (iv) to
effect the liquidation, dissolution or winding up of the Company, or (v) to
declare or pay any dividend on the Common Stock payable in Common Stock or to
effect a subdivision, combination or consolidation of the Common Stock (by
reclassification or otherwise than by payment of dividends in Common Stock),
then, in each such case, the Company shall give to each holder of a Right
Certificate, in accordance with Section 26 hereof, a notice of such proposed
action, which

                                                                              70


shall specify the record date for the purposes of such stock dividend, or
distribution of rights or warrants, or the date on which such liquidation,
dissolution or winding up is to take place and the date of participation therein
by the holders of the Common Stock and/or Preferred Stock, if any such date is
to be fixed, and such notice shall be so given in the case of any action covered
by clause (i) or (ii) above at least 10 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 10 days prior to the date of the
taking of such proposed action or the date of participation therein by the
holders of the Common Stock and/or Preferred Stock, whichever shall be the
earlier.

            (b) In case any event described in Section 11(a)(ii) or Section 13
shall occur then the Company shall as soon as practicable thereafter give to
each holder of a Right Certificate (or if occurring prior to the Distribution
Date, the holders of the Common Stock) in accordance with Section 26 hereof, a
notice of the occurrence of such event, which notice shall describe such event
and the consequences of such event to holders of Rights under Section 11(a)(ii)
and Section 13 hereof.

            Section 26. Notices. Notices or demands authorized by this Agreement
to be given or made by the Rights Agent or by the holder of any Right

            Section 27. Supplements and Amendments. Except as otherwise provided
in this Section 27, for so long as the Rights are then redeemable, the Company
may in its sole and absolute discretion, and the Rights Agent shall if the
Company so directs, supplement or amend any provision of this Agreement in any
respect without the approval of any holders of the Rights. At any time when the

supplement or amendment shall adversely affect the interests of the holders of
Rights as such (other than an Acquiring Person or an Affiliate or Associate of
an Acquiring Person), and no such amendment may cause the rights again to become
redeemable or cause the Agreement again to become amendable other than in
accordance with this sentence. Notwithstanding anything contained in this
Agreement to the contrary, no supplement or amendment shall be made which
decreases the Redemption Price. Upon the delivery of a certificate from an

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

            Section 30. Determinations and Actions by the Board of Directors.

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

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

            IMS Health Incorporated, a corporation organized and existing under
the General Corporation Law of the State of Delaware (hereinafter called the
"Company"), hereby certifies that the following resolution was duly adopted by
the Board of Directors of the Company as required by Section 151 of the General
Corporation Law of the State of Delaware at a meeting duly called and held on
June 15, 1998.

            RESOLVED, that pursuant to the authority granted to and vested in
the Board of Directors of the Company (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Company's
Certificate of Incorporation, as amended to date (hereinafter called the
"Certificate of Incorporation"), the Board of Directors hereby creates a series
of Preferred Stock, par value $.01 per share, of the Company and hereby states
the designation and number of shares, and fixes the relative rights, powers and
preferences thereof, and the limitations thereof, as follows:

            Section 1. Designation and Amount. The shares of such series shall
be designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 500,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors; provided, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Company convertible
into Series A Preferred Stock.


                                       A-1

            Section 2. Dividends and Distributions.

            (A) Subject to the rights of the holders of any shares of any series
of Preferred Stock of the Company (the "Preferred Stock") (or any similar stock)
ranking prior and superior to the Series A Preferred Stock with respect to
dividends, the holders of shares of Series A Preferred Stock, in preference to
the holders of Common Stock, par value $.01 per share, of the Company (the
"Common Stock") and of any other stock of the Company ranking junior to the
Series A Preferred Stock, shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash on the last day of January, April, July, and
October in each year (each such date being referred to herein as a "Dividend
Payment Date"), commencing on the first Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A Preferred Stock, in an
amount per share (rounded to the nearest cent) equal to the greater of (a) $10
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, declared
on the Common Stock since the immediately preceding Dividend Payment Date or,
with respect to the first Dividend Payment Date, since the first issuance of any
share or fraction of a share of Series A Preferred Stock. In the event the
Company shall at any time after June 15, 1998 declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

            (B) The Company shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Dividend Payment Date and the next subsequent
Dividend Payment Date, a dividend of $10 per share on the Series A Preferred
Stock shall nevertheless be payable, when, as and if declared, on such
subsequent Dividend Payment Date.


                                       A-2
<PAGE>

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

            Section 3. Voting Rights. The holders of shares of Series A
Preferred Stock shall have the following voting rights;

            (A) Subject to the provision for adjustment hereinafter set forth
      and except as otherwise provided in the Certificate of Incorporation or
      required by law, each share of Series A Preferred Stock shall entitle the
      holder thereof to 1000 votes on all matters upon which the holders of the
      Common Stock of the Company are entitled to vote. In the event the Company
      shall at any time after June 15, 1998 declare or pay any dividend on the
      Common Stock payable in shares of Common Stock, or effect a subdivision or
      combination or consolidation of the outstanding shares of Common Stock (by
      reclassification or otherwise than by payment of a dividend in shares of
      Common Stock) into a greater or lesser number of shares of Common Stock,
      then in each such case the number of votes per share to which holders of
      shares of Series A Preferred Stock were entitled immediately prior to such
      event shall be adjusted by multiplying such number by a fraction, the
      numerator of which is the number of shares of Common Stock outstanding
      immediately after such event and the denominator of which is the number of
      shares of Common Stock that were outstanding immediately prior to such
      event.

            (B) Except as otherwise provided herein, in the Certificate of
      Incorporation or in any other Certificate of Designations creating a
      series of Preferred Stock or any similar stock, and except as otherwise
      required by law, the holders of shares of Series A Preferred Stock and the


                                       A-3
<PAGE>

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

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

            Section 4. Certain Restrictions.

            (A) 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 earned or declared, on shares of Series A
      Preferred Stock outstanding shall have been paid in full, the Company
      shall not:

                  (i) declare or pay dividends, or make any other distributions,
            on any shares of stock ranking junior (as to dividends) to the
            Series A Preferred Stock;

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

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

                  (iv) redeem or purchase or otherwise acquire for consideration
            any shares of Series A Preferred Stock, or any shares of stock
            ranking on a parity (either as to dividends or upon liquidation,
            dissolution or winding up) with the Series A Preferred Stock, except
            in accordance with a purchase offer made in writing or by
            publication (as determined by the Board of


                                       A-4
<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.

            (B) 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 paragraph (A) of this Section 4,
      purchase or otherwise acquire such shares at such time and in such manner.

            Section 5. Reacquired Shares. Any shares of Series A Preferred Stock
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 retirement 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 any
conditions and restrictions on issuance set forth herein.

            Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (A) to the holders of the Common Stock or of shares of any other stock of
the Company ranking junior, upon liquidation, dissolution or winding up, to the
Series A Preferred Stock unless, prior thereto, the holders of shares of Series
A Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not earned or
declared, to the date of such payment, provided that the holders of shares of
Series A Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal to
1000 times the aggregate amount to be distributed per share to holders of shares
of Common Stock, or (B) to the holders of shares of stock ranking on a parity
upon liquidation, dissolution or winding up with the Series A Preferred Stock,
except distributions made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. In the
event, 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 classes and series of stock of the Company, if any, that rank on a
parity with the Series A Preferred Stock in respect thereof, then the assets
available for such distribution shall be distributed ratably to the holders of
the Series A Preferred Stock and the holders of such parity shares in the
proportion to their respective liquidation preferences. In the event the Company
shall at any time after June 15, 1998 declare or pay any dividend


                                       A-5
<PAGE>

on the Common Stock payable in shares of Common Stock, or effect a subdivision
or combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the proviso in clause
(A) 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.

            Section 7. Consolidation, Merger, etc. In case the Company shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are converted into, exchanged for or changed into
other stock or securities, cash and/or any other property, then in any such case
each share of Series A Preferred Stock shall at the same time be similarly
converted into, exchanged for 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 converted, exchanged or converted. In the event the Company shall at any time
after June 15, 1998 declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount set forth in
the preceding sentence with respect to the conversion, exchange or change of
shares of Series A Preferred Stock shall be adjusted by multiplying such amount
by a fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

            Section 8. No Redemption. The shares of Series A Preferred Stock
shall not be redeemable from any holder.

            Section 9. Rank. The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up of the Company, junior to all other
series of Preferred Stock and senior to the Common Stock.

            Section 10. Amendment. If any proposed amendment to the Certificate
of Incorporation (including this Certificate of Designations) would alter,
change or repeal any of the preferences, powers or special rights given to the
Series A


                                       A-6
<PAGE>

Preferred Stock so as to affect the Series A Preferred Stock adversely, then the
holders of the Series A Preferred Stock shall be entitled to vote separately as
a class upon such amendment, and the affirmative vote of two-thirds of the
outstanding shares of the Series A Preferred Stock, voting separately as a
class, shall be necessary for the adoption thereof, in addition to such other
vote as may be required by the General Corporation Law of the State of Delaware.

            Section 11. Fractional Shares. Series A Preferred Stock may be
issued in fractions of a share that 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 Stock.

      UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS
      OWNED BY OR TRANSFERRED TO ANY PERSON WHO BECOMES AN ACQUIRING PERSON (AS
      DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN TRANSFEREES THEREOF WILL
      BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                          SUMMARY OF RIGHTS TO PURCHASE
                            Shares of Preferred Stock

            On June 15, 1998 the Board of Directors of IMS Health Incorporated
(the "Company") declared a dividend of one preferred share purchase right (a
"Right") for each outstanding share of common stock, par value $.01 per share of
the Company (the "Common Stock"). The dividend is payable on June 29, 1998 (the
"Record Date") to the stockholders of record on that date. Each Right entitles
the registered holder to purchase from the Company one one-thousandth of a share
of Series A Junior Participating Preferred Stock, par value $.01 per share (the
"Preferred Stock") of the Company at a price of $225 per one one-thousandth of a
share of Preferred Stock (as the same may be adjusted, the "Purchase Price"),
subject to adjustment. The description and terms of the Rights are set forth in
a Rights Agreement dated as of June 15, 1998 as the same may be amended from
time to time (the "Rights Agreement"), between the Company and First Chicago
Trust Company of New York as Rights Agent (the "Rights Agent").

            Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions an "Acquiring Person") have acquired beneficial ownership of
15% or more (20% or more in the case of an "Institutional Investor" as defined)
of the outstanding shares of Common Stock or (ii) 10 business days (or such
later date as may be determined by action of the Board of Directors prior to
such time as any person or group of affiliated persons becomes an Acquiring
Person) following the commencement of, or announcement of an intention to make,
a tender offer or exchange offer the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the outstanding
shares of Common Stock (the earlier of such dates being called the "Distribution
Date"), the Rights will be evidenced by such Common Stock certificate together
with a copy of this Summary of Rights.

            The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights), the Rights will be transferred
with and only with the Common Stock. Until the Distribution Date (or earlier
redemption or expiration of the Rights), Common Stock certificates will contain
a notation incorporating the Rights Agreement by reference. Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any certificates for shares of Common Stock
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights, will also constitute the transfer of the Rights associated
with the shares of Common Stock represented by such certificate. As soon as
practicable following the Distribution
<PAGE>

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

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

            The Purchase Price payable, and the number of shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (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 or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-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 or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

            The Rights are also subject to adjustment in the event of a stock
dividend on the Common Stock payable in shares of Common Stock or subdivisions,
consolidations or combinations of the Common Stock occurring, in any such case,
prior to the Distribution Date.

            Shares of Preferred Stock purchasable upon exercise of the Rights
will not be redeemable. Each share of Preferred Stock will be entitled, when, as
and if declared, to a minimum preferential quarterly dividend payment of $10 per
share but will be entitled to an aggregate dividend of 1000 times the dividend
declared per share of Common Stock. In the event of liquidation, dissolution or
winding up of the Company, the holders of the Preferred Stock will be entitled
to a minimum preferential liquidation payment of $100 per share (plus any
accrued but unpaid dividends) but will be entitled to an aggregate payment of
1000 times the payment made per share of Common Stock. Each share of Preferred
Stock will have 1000 votes, voting together with the Common Stock. Finally, in
the event of any merger, consolidation or other transaction in which shares of
Common Stock are converted or exchanged, each share of Preferred Stock will be
entitled to receive 1000 times the amount received per share of Common Stock.
These rights are protected by customary antidilution provisions.

            Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of the one


                                        2
<PAGE>

one-thousandth interest in a share of Preferred Stock purchasable upon exercise
of each Right should approximate the value of one share of Common Stock.

            In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right and payment
of the Purchase Price, that number of shares of Common Stock having a market
value of two times the Purchase Price.

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

            At any time after any person or group becomes an Acquiring Person
and prior to the acquisition by such person or group of 50% or more of the
outstanding shares of Common Stock or the occurrence of an event described in
the prior paragraph, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or a fractional share of Preferred Stock (or of a share of a similar class or
series of the Company's preferred stock having similar rights, preferences and
privileges) of equivalent value, per Right (subject to adjustment).

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

            At any time prior to the time an Acquiring Person becomes such, the
Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (the "Redemption Price"). The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may


                                        3
<PAGE>

establish. Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

            For so long as the Rights are then redeemable, the Company may,
except with respect to the redemption price, amend the Rights in any manner.
After the Rights are no longer redeemable, the Company may, except with respect
to the redemption price, amend the Rights in any manner that does not adversely
affect the interests of holders of the Rights.

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

            A copy of the Rights Agreement has been filed with the Securities
and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A
dated June 23, 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,
as the same may be amended from time to time, which is hereby incorporated
