                                RIGHTS AGREEMENT

            Rights Agreement, dated as of _________ ___, 2000 (as amended,
supplemented or otherwise modified from time to time, the "Rights Agreement")
between The New D&B Corporation, a Delaware corporation (the "Company"), and
EquiServe Trust Company, N.A. (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 _________ ___, 2000 (the "Record Date") each
Right representing the right to purchase one 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 earlier of the
Distribution Date and the 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 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:

            Section 1. Certain Definitions. For purposes of this Rights
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
<PAGE>   4
                                                                               2


      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" becomes the
      Beneficial Owner of a number of shares of Common Stock such that the
      Person would otherwise qualify as an "Acquiring Person" 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, then such Person shall not be deemed
      to be or to have become an "Acquiring Person" for any purposes of this
      Rights Agreement unless and until such Person shall have failed to divest
      itself, as soon as practicable (as determined, in good faith, by the Board
      of Directors of the Company), of Beneficial Ownership of a sufficient
      number of shares of Common Stock so that such Person would no longer
      otherwise qualify as an "Acquiring Person". Notwithstanding the foregoing,
      (i) the sole stockholder of the Company at the time of the adoption of
      this Rights Agreement will not be deemed an Acquiring Person for any
      purposes of this Rights 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
<PAGE>   5
                                                                               3


      Person to 15% or more of the shares of Common Stock then outstanding,
      provided, however, that if a Person shall become the Beneficial Owner of
      15% or more 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
      beneficially own 15% or more of the shares of Common Stock then
      outstanding. For all purposes of this Rights 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 Rights 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:

                                                                               4


                  (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
            Rights 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 group members
            with respect to a bona fide public offering of securities), or upon
            the exercise of conversion rights, exchange rights, rights, warrants
            or options, or otherwise; provided, however, that a Person shall not
            be deemed the Beneficial Owner of, or to beneficially own, (x)
            securities tendered pursuant to a tender or exchange offer made by
            or on behalf of such Person or any of such Person's Affiliates or
            Associates until such tendered securities are accepted for purchase,
            (y) securities which such Person has a right to acquire on the
            exercise of Rights at any time prior to the time any Person becomes
            an Acquiring Person or (z) securities issuable upon exercise of
            Rights from and after the time a Person becomes an Acquiring Person
            if such Rights were acquired by such Person or any of such Person's
            Affiliates or Associates prior to the Distribution Date or pursuant
            to Section 3(a) or Section 22 hereof ("original Rights") or pursuant
            to Section 11(i) or Section 11(n) with respect to an adjustment to
            original Rights; or (B) the right to vote pursuant to any agreement,
            arrangement or understanding; provided, however, that a Person shall
            not be deemed the Beneficial Owner of, or to beneficially own, any
<PAGE>   7
                                                                               5


            security by reason of such agreement, arrangement or understanding
            if the agreement, arrangement or understanding to vote such security
            (1) arises solely from a revocable proxy or consent given to such
            Person in response to a public proxy or consent solicitation made
            pursuant to, and in accordance with, the applicable rules and
            regulations promulgated under the Exchange Act and (2) is not also

            comparable or successor report); or (iii) which are beneficially
            owned, directly or indirectly, by any other Person with which such
            Person or any of such Person's Affiliates or Associates has any
            agreement, arrangement or understanding (other than customary
            agreements with and between underwriters and selling group members
            with respect to a bona fide public offering of securities) for the
            purpose of acquiring, holding, voting (except to the extent
            contemplated by the proviso to Section 1(c)(ii)(B)) or disposing of
            such securities of the Company; provided, however, that no Person
            who is an officer, director or employee of an Exempt Person shall be
            deemed, solely by reason of such Person's status or authority as
            such, to be the "Beneficial Owner" of, to have "Beneficial
            Ownership" of or to "beneficially own" any securities that are
            "beneficially owned" (as defined in this Section 1(c)), including,
            without limitation, in a fiduciary capacity, by an Exempt Person or
            by any other such officer, director or employee of an Exempt Person.

by the certificates for Common Stock registered in the names of the holders
thereof and not by separate
<PAGE>   11
                                                                               9


Right Certificates, and (y) the Rights will be transferable only in connection
with the transfer of Common Stock. As soon as practicable after the Distribution
Date, the Company will prepare and execute, the Rights Agent will countersign,
and the Company will send or cause to be sent (and the Rights Agent will, if
requested, send) by first-class, insured, postage-prepaid mail, to each record
holder of Common Stock as of the close of business on the Distribution Date
(other than any Acquiring Person or any Associate or Affiliate of an Acquiring
Person), at the address of such holder shown on the records of the Company, a
Right Certificate, in substantially the form of Exhibit B hereto (a "Right
Certificate"), evidencing one Right (subject to adjustment as provided herein)
for each share of Common Stock so held. As of the Distribution Date, the Rights
will be evidenced solely by such Right Certificates.

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

            Rights shall be issued in respect of all shares of Common Stock
issued or disposed of (including, without limitation, upon disposition of Common
Stock out of treasury stock or issuance or reissuance of Common Stock out of
authorized but unissued shares) after the Record Date but prior to the earlier
of the Distribution Date and the Expiration Date, or in certain circumstances
provided in Section 22 hereof, after the Distribution Date. Certificates issued
for Common Stock (including, without limitation, upon transfer of outstanding
Common Stock, disposition of Common Stock out of treasury stock or issuance or
reissuance of Common Stock out of authorized but unissued shares) after the
Record Date but prior to the earlier of the Distribution Date and the Expiration
Date shall have impressed on, printed on, written on or otherwise affixed to
them the following legend:

           This certificate also evidences and entitles the holder hereof to
           certain rights as set forth in a Rights Agreement between The Dun &
           Bradstreet Corporation (formerly known as The New D&B Corporation)
           and EquiServe Trust Company, dated as of _________ ___, 2000 (as the
           same may be amended, supplemented or otherwise modified from time to
           time, the "Rights Agreement"), the terms of which are hereby
           incorporated herein by reference and a copy of which is on file at
           the principal executive offices of The Dun & Bradstreet Corporation.
           Under certain circumstances, as set forth in the Rights Agreement,
           such Rights will be evidenced by separate certificates and will no
           longer be evidenced by this certificate. The Dun & Bradstreet
           Corporation 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 is or
           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

                                                                              11


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 canceled 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 Rights 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 Rights
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 this Rights Agreement, 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 Purchase Price (as determined pursuant to Section 7), but the number of such
one one-thousandths of a share of Preferred Stock and the Purchase Price shall
be subject to adjustment as provided herein.

            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,
<PAGE>   14
                                                                              12


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 Rights Agreement any such Person was not such an officer.

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

            Section 6. Transfer, Split Up, Combination and Exchange of Right
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. (a)
Subject to the provisions of this Rights Agreement, at any time after the close
of business on the Distribution Date, and prior to
<PAGE>   15
                                                                              13


the close of business on the 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 or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

            (b) Subject to the provisions of this Rights Agreement, at any time
after the Distribution Date and prior to the Expiration Date, upon receipt by
the Company and the Rights Agent of evidence reasonably satisfactory to them of
the loss, theft, destruction or mutilation of a Right Certificate, and, in case
of loss, theft or destruction, of indemnity or security 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
Rights. (a) Except as otherwise provided herein, the Rights shall become
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
otherwise provided herein, exercise the Rights evidenced thereby in whole or in
part upon surrender of the Right Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the
office or agency of the Rights Agent designated for such purpose, together with
payment of the Purchase Price for each one one-thousandth of a share of
Preferred Stock (or other securities, cash or other assets, as the case may be)
as to which the Rights are exercised, at any time which is both after the
Distribution Date and prior to the time (the "Expiration Date") that is the
earliest of (i) the close of business on _________ ___, 2010 (the "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 hereof (the "Redemption Date") or (iii) the time at which such Rights
are exchanged as provided in Section 24 hereof.

            (b) The Purchase Price shall be initially $150 for each one
one-thousandth of a share of Preferred Stock purchasable upon the exercise of a
Right. The Purchase Price and the number of one one-thousandths of a share of
Preferred Stock or other securities or property to be acquired upon exercise of
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
Certificate representing exercisable Rights, with the form of election to
purchase duly executed, accompanied by payment of the aggregate Purchase Price
for the shares of Preferred Stock to be
<PAGE>   17
                                                                              15


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

            (d) Except as otherwise provided herein, in case the registered
holder of any Right Certificate shall exercise less than all the Rights
evidenced thereby, a new Right Certificate evidencing Rights equivalent to the
exercisable Rights remaining unexercised shall be issued by the Rights Agent to
the registered holder of such Right Certificate or to his duly authorized
assigns, subject to the provisions of Section 14 hereof.
<PAGE>   18
                                                                              16


            (e) Notwithstanding anything in this Rights Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder of Rights upon the
occurrence of any purported transfer or exercise of Rights pursuant to Section 6
hereof or this Section 7 unless such registered holder shall have (i) completed
and signed the certificate contained in the form of assignment or election to
purchase set forth on the reverse side of the Rights Certificate surrendered for
such transfer or exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) thereof as the
Company shall reasonably request.

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

            Section 9. Availability of Shares of Preferred Stock. (a) The
Company covenants and agrees that it will cause to be reserved and kept
available out of its authorized and unissued shares of Preferred Stock or any
shares of Preferred Stock held in its treasury, the number of
<PAGE>   19
                                                                              17


shares of Preferred Stock that will be sufficient to permit the exercise in full
of all outstanding Rights.

            (b) So long as the shares of Preferred Stock (and, following the
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
the time that a Person first 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 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
<PAGE>   20
                                                                              18


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 Rights 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
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
<PAGE>   21
                                                                              19


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 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 and Kind 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.

                                                                              20


            (a) (i) In the event the Company shall at any time after the date of
            this Agreement (A) declare and pay a dividend on the Preferred Stock
            payable in shares of Preferred Stock, (B) subdivide the outstanding
            Preferred Stock, (C) combine the outstanding Preferred Stock into a
            smaller number of shares of Preferred Stock or (D) issue any shares
            of its capital stock in a reclassification of the Preferred Stock
            (including any such reclassification in connection with a
            consolidation or merger in which the Company is the continuing or
            surviving corporation), except as otherwise provided in this Section
            11(a), the number and kind of shares of capital stock issuable on
            the effective date of such subdivision, combination or
            reclassification or at the time of the record date for such
            dividend, as the case may be, 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 Rights 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 Person becoming an Acquiring Person
            multiplied by the number of one one-thousandths of a share of
            Preferred Stock
<PAGE>   23
                                                                              21


            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 Section 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 Rights 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 (as so adjusted) 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 Rights
            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
<PAGE>   24
                                                                              22


            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
            Rights 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 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 canceled. 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
<PAGE>   25
                                                                              23


            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,
            with respect to such deficiency, to the extent permitted by
            applicable law and any material agreements then in effect to which
            the Company is a 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 such
            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,

            (6) any combination of the foregoing, 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 such 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 such 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
            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

                                                                              25


            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 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

                                                                              26


      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 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
<PAGE>   29
                                                                              27


      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 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 no event shall the
      consideration to be paid upon the exercise of one Right be less than the
      aggregate par value
<PAGE>   30
                                                                              28


      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 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
<PAGE>   31
                                                                              29


      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 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 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 Expiration Date.

            (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.

                                                                              31


            (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
      purchasable upon the exercise of 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 pursuant to Sections 11(b) or 11(c) hereof 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 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
<PAGE>   34
                                                                              32


      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 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
<PAGE>   35
                                                                              33


      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 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 adjustments in the Purchase Price,
      in addition to those adjustments expressly required by this Section 11, as
      and to the extent that it in its sole discretion shall determine to be
      advisable in order that any consolidation or subdivision of the Preferred
      Stock, issuance (wholly for cash) of any shares of Preferred Stock at less
      than the current market price, issuance (wholly for cash) of 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

                                                                              34


      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 Rights Agreement to the contrary
      notwithstanding, in the event that at any time after the date of this
      Rights Agreement and prior to the Distribution Date, the Company shall (i)
      declare or pay any dividend on the 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 shares 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 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 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
<PAGE>   38
                                                                              36

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 Rights 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
exercise of each Right shall be further adjusted as provided in Section 11(f) of
this Rights 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 Rights Agreement; (C) the
term "Company" shall thereafter be deemed to refer
<PAGE>   39
                                                                              37

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, 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
<PAGE>   40
                                                                              38

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 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 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
<PAGE>   41
                                                                              39

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.

           (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 Rights 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 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
<PAGE>   42
                                                                              40

exchange, to list or admit to trading (or 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 a provision in any of its
authorized securities or in its certificate of incorporation or by-laws or other
instrument governing its 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 or Common Stock equivalents of such Principal Party at less than the then
current market price per share thereof (determined pursuant to Section 11(d)
hereof) or securities exercisable for, or convertible into, Common Stock or
Common Stock equivalents of such 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
<PAGE>   43
                                                                              41

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 canceled, 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 or other transaction, the stockholders of the Person who
constitutes, or would constitute, the Principal Party for purposes of Section
13(b) 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 (except prior to the
Distribution Date in accordance with Section 11(n) hereof) or to distribute
Right Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
<PAGE>   44
                                                                              42

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

           (b) The Company shall not be required to issue fractions of 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
<PAGE>   45
                                                                              43

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 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 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.

                                                                              44

           (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 or exchange of a Right (except as provided above).

           Section 15. Rights of Action. All rights of action in respect of this
Rights 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 Rights 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 Rights 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 Rights 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:
<PAGE>   47
                                                                              45

           (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,
      subject to Section 7(e) hereof, 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 or exchange of the Rights represented thereby, nor shall anything
contained herein or in any Right Certificate be construed to confer upon the
holder of any Right Certificate, as such, any of the rights of a stockholder of
the Company or any right to vote for the election of directors or upon any
matter submitted to stockholders at any meeting thereof, or to give or withhold
consent to any corporate action, or to receive notice of meetings or other
actions affecting stockholders (except as provided in this Rights Agreement), or
to receive
<PAGE>   48
                                                                              46

dividends or subscription rights, or otherwise, until the Rights evidenced by
such Right Certificate shall have been exercised or exchanged 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 Rights 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
gross 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 Rights 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 Rights Agreement in reliance upon any Right
Certificate or certificate for the Preferred Stock or Common Stock or for other
securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, direction, consent,
certificate, statement, or other paper or document believed by it to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper Person or Persons, or otherwise upon the advice of counsel as set
forth in Section 20 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
<PAGE>   49
                                                                              47

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 Rights 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 Rights
Agreement, any of the Right Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the
predecessor Rights Agent and deliver such Right Certificates so countersigned;
and in case at that time any of the Right Certificates shall not have been
countersigned, any successor Rights Agent may countersign such Right
Certificates either in the 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 Rights
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 Rights Agreement.

           Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Rights 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 Rights
      Agreement the Rights Agent shall deem it necessary or desirable that any
      fact or matter be proved or established by the Company prior to taking or
      suffering any action hereunder, such fact or matter (unless other evidence
      in respect thereof be herein specifically prescribed) may be deemed to be
      conclusively proved and established by a certificate signed by any one of
      the Chairman of the Board 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 Rights 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 gross 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 Rights Agreement or
      in the Right Certificates (except its
<PAGE>   51
                                                                              49

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 Rights Agreement or the execution and delivery
      hereof (except the due execution hereof by the Rights Agent) or in respect
      of the validity or execution of any Right Certificate (except its
      countersignature thereof); nor shall it be responsible for any breach by
      the Company of any covenant or condition contained in this Rights
      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 Rights 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 Rights 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 Rights 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.

           (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
<PAGE>   53
                                                                              51

      though it were not Rights Agent under this Rights 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)
      or a transferee thereof, the Rights Agent shall not take any further
      action with respect to such requested exercise or transfer without first
      consulting with the Company.

           Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Rights
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
<PAGE>   54
                                                                              52

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 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
<PAGE>   55
                                                                              53

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 Rights Agreement or of the Rights to the contrary, the
Company may, at its option, issue new 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 Rights Agreement. In addition, in
connection with the issuance or sale of Common Stock following the Distribution
Date and prior to the 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
<PAGE>   56
                                                                              54

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, 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.

           Section 24. Exchange. (a) The Board of Directors 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
<PAGE>   57
                                                                              55

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 after an Acquiring 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 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
<PAGE>   58
                                                                              56

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 substitute 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 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
<PAGE>   59
                                                                              57

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 shall
specify the record date for the purposes of such stock dividend, or distribution
or offering of rights or warrants, or the date on which such liquidation,
dissolution, reclassification, subdivision, combination, consolidation 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
<PAGE>   60
                                                                              58

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

           One Diamond Hill Road
           Murray Hill, New Jersey  07974
           Attn:  Chief Legal Counsel

Subject to the provisions of Section 21 hereof, any notice or demand authorized
by this Rights Agreement to be given or made by the Company or by the holder of
any Right Certificate to or on the Rights Agent shall be sufficiently given or
made if sent by first-class mail, postage prepaid, addressed (until another
address is filed in writing with the Company) as follows:

Notices or demands authorized by this Rights Agreement to be given or made by
the Company or the Rights Agent to the holder of any Right Certificate shall be
sufficiently given or made if sent by first-class mail, postage prepaid,
addressed to such holder at the address of such holder as shown on the registry
books of the Company.

           Section 27. Supplements and Amendments. 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
<PAGE>   61
                                                                              59

any provision of this Rights Agreement in any respect without the approval of
any holders of the Rights. At any time when the Rights are no longer redeemable,
except as otherwise provided in this Section 27, the Company may, and the Rights
Agent shall, if the Company so directs, supplement or amend this Rights
Agreement without the approval of any holders of Rights Certificates in order to
(i) cure any ambiguity, (ii) correct or supplement any provision contained
herein which may be defective or inconsistent with any other provisions herein,
(iii) shorten or lengthen any time period hereunder, or (iv) change or
supplement the provisions hereunder in any manner which the Company may deem
necessary or desirable; provided that no such 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 this
Rights Agreement again to become amendable other than in accordance with this
sentence. Notwithstanding anything contained in this Rights Agreement to the
contrary, no supplement or amendment shall be made which decreases the
Redemption Price. Upon the delivery of a certificate from an appropriate officer
of the Company which states that the supplement or amendment is in compliance
with the terms of this Section 27, the Rights Agent shall execute such
supplement or amendment; provided that any supplement or amendment that does not
amend Sections 18, 19, 20 or 21 hereof in a manner adverse to the Rights Agent
shall become effective immediately upon execution by the Company, whether or not
also executed by the Rights Agent.

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

            Section 29. Benefits of this Rights Agreement. Nothing in this
Rights Agreement shall be construed to give to any Person other than the
Company, the Rights Agent and the registered holders of the Right Certificates
(and, prior to the Distribution Date, the Common Stock) any legal or equitable
right, remedy or claim under this Rights Agreement; but this Rights 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.
The Board of Directors of the Company shall have the exclusive power and

made by the Board of Directors of the Company in good faith, shall (x) be final,
conclusive and binding on the

restrictions of this Rights Agreement shall remain in full force and effect and
shall in no way be affected, impaired or invalidated.

Certificate issued hereunder shall be deemed to be a contract made under the

                  The New D&B Corporation, 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

                  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

                  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


                                      A-1
<PAGE>   66
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.

                  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 __________ __, 2000 declare and 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.

                  (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


                                      A-2
<PAGE>   67
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 __________
         __, 2000 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 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.

                  (D) If, at the time of any annual meeting of stockholders for
         the election of directors, the equivalent of six quarterly dividends
         (whether or not consecutive) payable on any share or shares of Series A
         Preferred Stock are in default, the number of directors


                                      A-3
<PAGE>   68
         constituting the Board of Directors of the Company shall be increased
         by two. In addition to voting together with the holders of Common Stock
         for the election of other directors of the Company, the holders of
         record of the Series A Preferred Stock, voting separately as a class to
         the exclusion of the holders of Common Stock, shall be entitled at said
         meeting of stockholders (and at each subsequent annual meeting of
         stockholders), unless all dividends in arrears on the Series A
         Preferred Stock have been paid or declared and set apart for payment
         prior thereto, to vote for the election of two directors of the
         Company, the holders of any Series A Preferred Stock being entitled to
         cast a number of votes per share of Series A Preferred Stock as is
         specified in paragraph (A) of this Section 3. Each such additional
         director shall not be a member of Class I, Class II or Class III of the
         Board of Directors of the Company, but shall serve until the next
         annual meeting of stockholders for the election of directors, or until
         his successor shall be elected and shall qualify, or until his right to
         hold such office terminates pursuant to the provisions of this Section
         3(D). Until the default in payments of all dividends which permitted
         the election of said directors shall cease to exist, any director who
         shall have been so elected pursuant to the provisions of this Section
         3(D) may be removed at any time, without cause, only by the affirmative
         vote of the holders of the shares of Series A Preferred Stock at the
         time entitled to cast a majority of the votes entitled to be cast for
         the election of any such director at a special meeting of such holders
         called for that purpose, and any vacancy thereby created may be filled
         by the vote of such holders. If and when such default shall cease to
         exist, the holders of the Series A Preferred Stock shall be divested of
         the foregoing special voting rights, subject to revesting in the event
         of each and every subsequent like default in payments of dividends.
         Upon the termination of the foregoing special voting rights, the terms
         of office of all persons who may have been elected directors pursuant
         to said special voting rights shall forthwith terminate, and the number
         of directors constituting the Board of Directors shall be reduced by
         two. The voting rights granted by this Section 3(D) shall be in
         addition to any other voting rights granted to the holders of the
         Series A Preferred Stock in this Section 3.

                  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 (either
                  as to dividends or upon liquidation, dissolution or winding
                  up) 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
                  (either as to dividends or upon liquidation, dissolution or
                  winding up) with the Series A Preferred Stock, except
                  dividends paid ratably


                                      A-4
<PAGE>   69
                  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 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


                                      A-5
<PAGE>   70
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 __________ __, 2000 declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the aggregate amount to which holders of shares of Series A Preferred
Stock were entitled immediately prior to such event under the proviso in clause
(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.

                  Neither the merger or consolidation of the Company into or
with another entity nor the merger or consolidation of any other entity into or
with the Company (nor the sale of all or substantially all of the assets of the
Company) shall be deemed to be a liquidation, dissolution or winding up of the
Company within the meaning of this Section 6.

                  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 __________ __, 2000 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.



                                      A-6
<PAGE>   71
                  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 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.

                  This certifies that ___________ or registered assigns, is the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the Rights

this Right Certificate are subject to modification and adjustment upon the
happening of certain events.

                  This Right Certificate is subject to all of the terms,
provisions and conditions of the Rights Agreement, which terms, provisions and
conditions are hereby incorporated herein by reference and made a part hereof
and to which Rights Agreement reference is hereby made for a full description of

Certificates, upon surrender at the office or agency of the Rights Agent
designated for such purpose, may be exchanged for another Right Certificate or
Right Certificates of like tenor and date evidencing Rights entitling the holder
to purchase a like aggregate number of shares of Preferred Stock as the Rights

                  No holder of this Right Certificate, as such, shall be
entitled to vote or receive dividends or be deemed for any purpose the holder of
the Preferred Stock or of any other securities of the Company which may at any
time be issuable on the exercise or exchange hereof, nor shall anything
contained in the Rights Agreement or herein be construed to confer upon the
holder hereof, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to

                                                                       Exhibit C

    UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS
    OWNED BY OR TRANSFERRED TO ANY PERSON WHO IS OR 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 _________ ___, 2000 the Board of Directors of The New D&B
Corporation (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 _________
___, 2000 (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 $150
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 _________
___, 2000 as the same may be amended from time to time (the "Rights Agreement"),
between the Company and EquiServe Trust Company, N.A., as Rights Agent (the
"Rights Agent").

         Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions an "Acquiring Person") have acquired beneficial ownership of
15% or more 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, with respect to any of the
Common Stock certificates outstanding as of the Record Date, 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


                                      C-1
<PAGE>   81
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.

         The Rights are not exercisable until the Distribution Date. The Rights
will expire on _________ ___, 2010 (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 the greater
of (a) $10 per share and (b) an amount equal to 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.

         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


                                      C-2
<PAGE>   82
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.

         For so long as the Rights are then redeemable, the Company may, except
with respect to the redemption price, amend the Rights Agreement 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 or exchanged, the holder thereof, as such,
will have no rights as a stockholder of the Company, including, without
limitation, the right to vote or to receive dividends.
