                                RIGHTS AGREEMENT

                  Rights Agreement, dated as of October 26, 2000 between Rohm
and Haas Company, a Delaware corporation (the "Company"), and EquiServe Trust
Company, NA (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 November 3, 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 earliest of the
Distribution Date, the Redemption Date and the Final Expiration Date (as such
terms are hereinafter defined); provided, however, that Rights may be issued
with respect to shares of Common Stock that shall become outstanding after the
Distribution Date and prior to the Redemption Date and the Final Expiration Date
in accordance with Section 22.

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

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

                  (a) "Acquiring Person" shall mean any Person (as such term is
         hereinafter defined) who or which shall be the Beneficial Owner (as
         such term is hereinafter defined) of 15% or more of the shares of
         Common Stock then outstanding, but shall not include an Exempt Person
         (as such term is hereinafter defined); provided, however, that if (i)
         the Board of Directors of the Company determines in good faith that a
         Person who would otherwise be an "Acquiring Person" has become such
         inadvertently (including, without limitation, because (A) 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
         (B) such Person was aware of the extent of its Beneficial Ownership of
         Common Stock but had no actual knowledge of the consequences of such
         Beneficial Ownership under this Rights Agreement) and without any
         intention of changing or influencing control of the Company, and such
         Person, as promptly as practicable after being advised of such
         determination divested or divests himself or itself of Beneficial
         Ownership of a sufficient number of shares of Common Stock so that such
         Person would no longer be an Acquiring Person, then such Person shall
         not be deemed to be or to have become an "Acquiring Person" for any
         purposes of this Agreement or (ii) if, as of the date hereof or prior
         to the first public announcement of the adoption of this Agreement, any
         Person is or becomes the Beneficial Owner of 15% or more of the shares
         of Common Stock outstanding, such Person shall not be deemed to be or
         to become an "Acquiring Person" unless and until

                                                                               2


         such time as such Person shall, after the first public announcement of
         the adoption of this Agreement, become the Beneficial Owner of
         additional shares of Common Stock (other than pursuant to a dividend or
         distribution paid or made by the Company on the outstanding Common
         Stock or pursuant to a split or subdivision of the outstanding Common
         Stock), unless, upon becoming the Beneficial Owner of such additional
         shares of Common Stock, such Person is not then the Beneficial Owner of
         15% or more of the shares of Common Stock. Notwithstanding the
         foregoing, no Person shall become an "Acquiring Person" as the result
         of an acquisition of shares of Common Stock by the Company which, by
         reducing the number of shares outstanding, increases the proportionate
         number of shares beneficially owned by such Person to 15% or more 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 own 15% or more of the shares of Common Stock then outstanding. For
         all purposes of this Agreement, any calculation of the number of shares
         of Common Stock outstanding at any particular time, including for
         purposes of determining the particular percentage of such outstanding
         shares of Common Stock of which any Person is the Beneficial Owner,
         shall be made in accordance with the last sentence of Rule
         13d-3(d)(1)(i) of the General Rules and Regulations under the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), as in
         effect on the date hereof. Notwithstanding the foregoing, the
         descendants of each of Otto Haas and his spouse, the spouses of such
         descendants and any trusts and foundations established by any of them
         (collectively, the "Haas Family") shall not be deemed to be or to
         become an "Acquiring Person" unless and until such time as the Haas
         Family shall become the Beneficial Owner of 35% or more of the shares
         of Common Stock outstanding.

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

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

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

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

                  underwriters and selling 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 a 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 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 then reportable on Schedule

                  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

                  (e) "close of business" on any given date shall mean 5:00
          P.M., New York City time, on such date; provided, however, that if

          unincorporated entity, the equivalent equity interest) with the
          greatest voting power of such other Person or, if such other Person is
          a subsidiary of another Person, the Person or Persons which ultimately
          control such first-mentioned Person.

                  (g) "Distribution Date" shall have the meaning set forth in

                  Section 3. Issue of Right Certificates. (a) Until the earlier
of (i) the tenth day after the Stock Acquisition Date or (ii) the tenth Business

result in any Person (other than an Exempt Person) becoming the Beneficial Owner
of shares of Common Stock aggregating 15% or more of the Common Stock then
outstanding (including any such date which is after the date of this Agreement
and prior to the issuance of the Rights), the earlier of such dates being herein
referred to as the "Distribution Date"), (x) the Rights will be evidenced

Common Stock registered in the names of the holders thereof and not by separate
Right Certificates, and (y) the Rights will be transferable only in connection

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 the earlier of the Redemption Date or the Final 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.

                  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 earliest

                  and Haas Company and EquiServe Trust Company, NA, dated as of
                  October 26, 2000 as the same may be amended from time to time
                  (the "Rights Agreement"), the terms of which are hereby
                  incorporated herein by reference and a copy of which is on
                  file at the principal executive offices of Rohm and Haas
                  Company. 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. Rohm and Haas Company will mail to the holder of
                  this certificate a copy of the Rights Agreement without charge
                  after receipt of a written request therefor. Under certain
                  circumstances, as set forth in the Rights Agreement, Rights
                  owned by or transferred to any Person who becomes an Acquiring
                  Person (as defined in the Rights Agreement) and certain
                  transferees thereof will become null and void and will no
                  longer be transferable.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Stock represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Stock represented thereby. In the event that the Company purchases or
otherwise acquires any Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such Common Stock shall be deemed
cancelled and retired so that the Company shall not be entitled to exercise any
Rights associated with the Common Stock which are no longer outstanding.

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

                  Section 4. Form of Right Certificates. The Right Certificates
(and the forms of election to purchase shares and of assignment to be printed on
the reverse thereof) shall be substantially in the form set forth in Exhibit B
hereto and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of the New York
Stock Exchange or of any other stock exchange or automated quotation system on
which the Rights may from time to time be listed, or to conform to usage.
Subject to the provisions of Sections 11, 13 and 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such number of one
one-thousandths of a share of Preferred Stock as shall be set forth therein at
the price per one one-thousandth of a share of Preferred Stock set forth therein
(the "Purchase Price"), but the number of such one one-thousandths of a share of
Preferred Stock and the Purchase Price shall be subject to adjustment as
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, 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, or shall have attested to the Company's seal thereon,
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, or who attested the Company's seal thereon, had not
ceased to be such officer of the Company; and any Right Certificate may be
signed on behalf of the Company, and the Company's seal may be attested, by any
Person who, at the actual date of the execution of such Right Certificate, shall
be a proper officer of the Company to sign such Right Certificate, although at
the date of the execution of this Agreement any such Person was not such an
officer.

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

                                                                               8


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 as to which the Rights are exercised, at any time which is both
after the Distribution Date and prior to the earliest of (i) the close of
business on December 1, 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 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
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


<PAGE>   9
                                                                               9


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.

                  (e) Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder 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 Right 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 cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right Certificates shall be issued in lieu thereof except as expressly permitted
by any of the provisions of this Agreement. The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all cancelled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such cancelled Right Certificates, and in such
case shall deliver a certificate of destruction thereof to the Company.

                  Section 9. 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 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 Final Expiration Date. The
Company may temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file a registration
statement under the Securities Act and permit it to become effective. Upon any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained and until a registration statement
under the Securities Act (if required) shall have been declared effective.

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

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

                  Section 10. Preferred Stock Record Date. Each Person in whose
name any certificate for Preferred Stock is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of the
shares of Preferred Stock represented thereby on, and such certificate shall be
dated, the date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that if the

                                                                              11


date of such surrender and payment is a date upon which the Preferred Stock
transfer books of the Company are closed, such Person shall be deemed to have
become the record holder of such shares on, and such certificate shall be dated,
the next succeeding Business Day on which the Preferred Stock transfer books of
the Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Right Certificate shall not be entitled to any rights of a holder of
Preferred Stock for which the Rights shall be exercisable, including, without
limitation, the right to vote or to receive dividends or other distributions,
and shall not be entitled to receive any notice of any proceedings of the
Company, except as provided herein.

                  Section 11. Adjustment of Purchase Price, Number of Shares and
Number of Rights. The Purchase Price, the number of shares of Preferred Stock or
other securities or property purchasable upon exercise of each Right and the
number of Rights outstanding are subject to adjustment from time to time as
provided in this Section 11.

                          (a)   (i)  In the event the Company shall at any time
                  after the date of this Agreement (A) declare a dividend on the
                  Preferred 18 Stock payable in shares of Preferred Stock, (B)
                  subdivide the outstanding Preferred Stock, (C) combine the
                  outstanding Preferred Stock into a smaller number of Preferred
                  Stock or (D) issue any shares of its capital stock in a
                  reclassification of the Preferred Stock (including any such
                  reclassification in connection with a consolidation or merger
                  in which the Company is the continuing or surviving
                  corporation), except as otherwise provided in this Section
                  11(a), the Purchase Price in effect at the time of the record
                  date for such dividend or of the effective date of such
                  subdivision, combination or reclassification, and the number
                  and kind of shares of capital stock issuable on such date,
                  shall be proportionately adjusted so that the holder of any
                  Right exercised after such time shall be entitled to receive
                  the aggregate number and kind of shares of capital stock
                  which, if such Right had been exercised immediately prior to
                  such date and at a time when the Preferred Stock transfer
                  books of the Company were open, the holder would have owned
                  upon such exercise and been entitled to receive by virtue of
                  such dividend, subdivision, combination or reclassification;
                  provided, however, that in no event shall the consideration to
                  be paid upon the exercise of one Right be less than the
                  aggregate par value of the shares of capital stock of the
                  Company issuable upon exercise of one Right.

                          (ii) Subject to Section 24 of this Agreement, in the
                  event that any Person becomes an Acquiring Person, then (A)
                  the Purchase Price shall be adjusted to be the Purchase Price
                  in effect immediately prior to such Person becoming an
                  Acquiring Person multiplied by the number of one
                  one-thousandths of a share of Preferred Stock for which a
                  Right was exercisable immediately prior to such Person
                  becoming an Acquiring Person, whether or not such Right was
                  then exercisable, and (B) each holder of a Right, except as
                  otherwise provided in this Section 11(a)(ii) and Subsection
                  11(a)(iii), hereof, shall thereafter have the right to
                  receive, upon exercise at a price equal to the Purchase Price
                  (as so adjusted), in accordance with the terms of this
                  Agreement and in lieu of shares of Preferred Stock, such
                  number of shares of Common Stock (or at the option of the
                  Company, such number of one one-thousandths of shares of
                  Preferred Stock) as


<PAGE>   12

                                                                              12


                  shall equal the result obtained by (x) multiplying the then
                  current Purchase Price by the number of one one-thousandths of
                  a share of Preferred Stock for which a Right is then
                  exercisable and dividing that product by (y) 50% of the then
                  current per share market price of the Company's Common Stock
                  (determined pursuant to Section 11(d) hereof) on the date such
                  Person became an Acquiring Person; provided, however, that the
                  Purchase Price and the number of shares of Common Stock so
                  receivable upon exercise of a Right shall thereafter be
                  subject to further adjustment as appropriate in accordance
                  with Section 11(f) hereof. Notwithstanding anything in this
                  Agreement to the contrary, however, from and after the time
                  (the "invalidation time") when any Person first becomes an
                  Acquiring Person, any Rights that are beneficially owned by
                  (x) any Acquiring Person (or any Affiliate or Associate of any
                  Acquiring Person), (y) a transferee of any Acquiring Person
                  (or any such Affiliate or Associate) who becomes a transferee
                  after the invalidation time or (z) a transferee of any
                  Acquiring Person (or any such Affiliate or Associate) who
                  became a transferee prior to or concurrently with the
                  invalidation time pursuant to either (I) a transfer from the
                  Acquiring Person to holders of its equity securities or to any
                  Person with whom it has any continuing agreement, arrangement
                  or understanding regarding the transferred Rights or (II) a
                  transfer which the Board of Directors has determined is part
                  of a plan, arrangement or understanding which has the purpose
                  or effect of avoiding the provisions of this paragraph, and
                  subsequent transferees of such Persons, shall be void without
                  any further action and any holder of such Rights shall
                  thereafter have no rights whatsoever with respect to such
                  Rights under any provision of this Agreement. The Company
                  shall use all reasonable efforts to ensure that the provisions
                  of this Section 11(a)(ii) are complied with, but shall have no
                  liability to any holder of Right Certificates or other Person
                  as a result of its failure to make any determinations with
                  respect to an Acquiring Person or its Affiliates, Associates
                  or transferees hereunder. From and after the invalidation
                  time, no Right Certificate shall be issued pursuant to Section
                  3 or Section 6 hereof that represents Rights that are or have
                  become void pursuant to the provisions of this paragraph, and
                  any Right Certificate delivered to the Rights Agent that
                  represents Rights that are or have become void pursuant to the
                  provisions of this paragraph shall be cancelled. From and
                  after the occurrence of an event specified in Section 13(a)
                  hereof, any Rights that theretofore have not been exercised
                  pursuant to this Section 11(a)(ii) shall thereafter be
                  exercisable only in accordance with Section 13 and not
                  pursuant to this Section 11(a)(ii).

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

                                                                              13


                  accordance with subparagraph (ii) upon exercise of the Right
                  and payment of the applicable Purchase Price, (1) cash, (2) a
                  reduction in the Purchase Price, (3) shares of Preferred Stock
                  or other equity securities of the Company (including, without
                  limitation, shares or fractions of shares of preferred stock
                  which, by virtue of having dividend, voting and liquidation
                  rights substantially comparable to those of the shares of
                  Common Stock, are deemed in good faith by the Board of
                  Directors to have substantially the same value as the shares
                  of Common Stock (such shares of preferred stock and shares or
                  fractions of shares of preferred stock are hereinafter
                  referred to as "Common Stock equivalents"), (4) debt
                  securities of the Company, (5) other assets, or (6) any
                  combination of the foregoing, having a value which, when added
                  to the value of the shares of Common Stock actually issued
                  upon exercise of such Right, shall have an aggregate value
                  equal to the Current Value (less the amount of any reduction
                  in the Purchase Price), where such aggregate value has been
                  determined by the Board of Directors upon the advice of a
                  nationally recognized investment banking firm selected in good
                  faith by the Board of Directors; provided, however, if the
                  Company shall not make adequate provision to deliver value
                  pursuant to clause (B) above within thirty (30) days following
                  the date that the Acquiring Person became such (the "Section
                  11(a)(ii) Trigger Date"), then the Company shall be obligated
                  to deliver, to the extent permitted by applicable law and any
                  material agreements then in effect to which the Company is a
                  party, upon the surrender for exercise of a Right and without
                  requiring payment of the Purchase Price, shares of Common
                  Stock (to the extent available), and then, if necessary, such
                  number or fractions of shares of Preferred Stock (to the
                  extent available) and then, if necessary, cash, which shares
                  and/or cash have an aggregate value equal to the Spread. If,
                  upon the date any Person becomes an Acquiring Person, the
                  Board of Directors shall determine in good faith that it is
                  likely that sufficient additional shares of Common Stock could
                  be authorized for issuance upon exercise in full of the
                  Rights, then, if the Board of Directors so elects, the thirty
                  (30) day period set forth above may be extended to the extent
                  necessary, but not more than ninety (90) days after the
                  Section 11(a)(ii) Trigger Date, in order that the Company may
                  seek stockholder approval for the authorization of such
                  additional shares (such thirty (30) day period, as it may be
                  extended, is herein called the "Substitution Period"). To the
                  extent that the Company determines that some action need be
                  taken pursuant to the second and/or third sentence of this
                  Section 11(a)(iii), the Company (x) shall provide, subject to
                  Section 11(a)(ii) hereof and the last sentence of this Section
                  11(a)(iii) hereof, that such action shall apply uniformly to
                  all outstanding Rights and (y) may suspend the exercisability
                  of the Rights until the expiration of the Substitution Period
                  in order to seek any authorization of additional shares and/or
                  to decide the appropriate form of distribution to be made
                  pursuant to such second sentence and to determine the value
                  thereof. In the event of any such suspension, the Company
                  shall issue a public announcement stating that the
                  exercisability of the Rights has been temporarily suspended,
                  as well as a public announcement at such time as the
                  suspension is no longer in effect. For purposes of this
                  Section 11(a)(iii), the value of the shares of Common Stock
                  shall be the current per share market price (as determined
                  pursuant to Section 11(d)(i)) on the Section 11(a)(ii) Trigger
                  Date and the per share or fractional value of any "Common
                  Stock equivalent" shall be deemed to equal the current per
                  share market price of the Common Stock. The Board of Directors
                  of the Company may, but shall not be required to, establish
                  procedures to allocate the right to receive shares of Common
                  Stock upon the exercise of the Rights among holders of Rights
                  pursuant to this Section 11(a)(iii).

                          (b) In case the Company shall fix a record date for
                  the issuance of rights, options or warrants to all holders of
                  Preferred Stock entitling them (for a period expiring within
                  45 calendar days after such record date) to subscribe for or
                  purchase Preferred Stock (or shares having similar rights,
                  privileges and preferences as the Preferred Stock ("equivalent
                  preferred shares")) or securities convertible into Preferred
                  Stock or equivalent preferred shares at a price per share of
                  Preferred Stock or equivalent preferred shares (or having a
                  conversion price per share, if a security convertible into
                  shares of Preferred Stock or equivalent preferred shares) less
                  than the then current per share market price of the Preferred
                  Stock (determined pursuant to Section 11(d) hereof) on such
                  record date, the Purchase Price to be in effect after such
                  record date shall be determined by multiplying the Purchase
                  Price in effect immediately prior to such record date by a
                  fraction, the numerator of which shall be the number of shares
                  of Preferred Stock and equivalent preferred shares outstanding
                  on such record date plus the number of shares of Preferred
                  Stock and equivalent preferred shares which the aggregate
                  offering price of the total number of shares of Preferred
                  Stock and/or equivalent preferred shares so to be offered
                  (and/or the aggregate initial conversion price of the
                  convertible securities so to be offered) would purchase at
                  such current market price, and the denominator of which shall
                  be the number of shares of Preferred Stock and equivalent
                  preferred shares outstanding on such record date plus the
                  number of additional shares of Preferred Stock and/or
                  equivalent preferred shares to be offered for subscription or
                  purchase (or into which the convertible securities so to be
                  offered are initially convertible); provided, however, that in
                  no event shall the consideration to be paid upon the exercise
                  of one Right be less than the aggregate par value of the
                  shares of capital stock of the Company issuable upon exercise
                  of one Right. In case such subscription price may be paid in a
                  consideration part or all of which shall be in a form other
                  than cash, the value of such consideration shall be as
                  determined in good faith by the Board of Directors of the
                  Company, whose determination shall be described in a statement
                  filed with the Rights Agent. Shares of Preferred Stock and
                  equivalent preferred shares owned by or held for the account
                  of the Company shall not be deemed outstanding for the purpose
                  of any such computation. Such adjustment shall be made
                  successively whenever such a 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 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 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

                                                                              16


                  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 date of the expiration of the
                  right to exercise any Rights.

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

                          (g) All Rights originally issued by the Company
                  subsequent to any adjustment made to the Purchase Price
                  hereunder shall evidence the right to purchase, at the
                  adjusted Purchase Price, the number of one one-thousandths of
                  a share of Preferred Stock purchasable from time to time
                  hereunder upon exercise of the Rights, all subject to further
                  adjustment as provided herein.

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

                          (i) The Company may elect on or after the date of any
                  adjustment of the Purchase Price to adjust the number of
                  Rights, in substitution for any adjustment in the number of
                  one one-thousandths of a share of Preferred Stock purchasable
                  upon the exercise of a Right. Each of the Rights outstanding
                  after such adjustment of the number of Rights shall be
                  exercisable for the number of one one-thousandths of a share
                  of Preferred Stock for which a Right was exercisable
                  immediately prior to such adjustment. Each Right held of
                  record prior to such adjustment of the number of Rights shall
                  become that number of Rights (calculated to the nearest one
                  ten-thousandth) obtained by dividing the Purchase Price in
                  effect immediately prior to adjustment of the Purchase Price
                  by the Purchase Price in effect immediately after adjustment
                  of the Purchase Price. The Company shall make a public
                  announcement of its election to adjust the number of Rights,
                  indicating the record date for the adjustment, and, if known
                  at the time, the amount of the adjustment to be made. This
                  record date may be the date on which the Purchase Price is
                  adjusted or any day thereafter, but, if the Right Certificates
                  have been issued, shall be at least 10 days later than the
                  date of the public announcement. If Right Certificates have
                  been issued, upon each adjustment of the number of Rights
                  pursuant to this Section 11(i), the Company may, as promptly
                  as practicable, cause to be distributed to holders of record
                  of Right Certificates on such record date Right Certificates
                  evidencing, subject to Section 14 hereof, the additional
                  Rights to which such holders shall be entitled as a result of
                  such adjustment, or, at the option of the Company, shall cause
                  to be distributed to such holders of record in substitution
                  and replacement for the Right Certificates held by such
                  holders prior to the date of adjustment, and upon surrender
                  thereof, if required by the Company, new Right Certificates
                  evidencing all the Rights to which such holders shall be
                  entitled after such adjustment. Right Certificates so to be
                  distributed shall be issued, executed and countersigned in the
                  manner provided for herein and shall be registered in the
                  names of the holders of record of Right Certificates on the
                  record date specified in the public announcement.

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

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

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

                                                                              18


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

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

                          (n) Anything in this Agreement to the contrary
                  notwithstanding, in the event that at any time after the date
                  of this Agreement and prior to the Distribution Date, the
                  Company shall (i) declare or pay any dividend on the Common
                  Stock payable in Common Stock or (ii) effect a subdivision,
                  combination or consolidation of the Common Stock (by
                  reclassification or otherwise than by payment of a dividend
                  payable in Common Stock) into a greater or lesser number of
                  Common Stock, then in any such case, the number of Rights
                  associated with each share of Common Stock then outstanding,
                  or issued or delivered thereafter, shall be proportionately
                  adjusted so that the number of Rights thereafter associated
                  with each share of Common Stock following any such event shall
                  equal the result obtained by multiplying the number of Rights
                  associated with each share of Common Stock immediately prior
                  to such event by a fraction the numerator of which shall be
                  the total number of shares of Common Stock outstanding
                  immediately prior to the occurrence of the event and the
                  denominator of which shall be the total number of shares of
                  Common Stock outstanding immediately following the occurrence
                  of such event.

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

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


<PAGE>   19
                                                                              19


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 11(a)(ii)) shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to the then current Purchase Price multiplied by the number of one
one-thousandths of a share of Preferred Stock for which a Right was exercisable
(whether or not such Right was then exercisable) immediately prior to the time
that any Person first became an Acquiring Person (each as subsequently adjusted
thereafter pursuant to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)),
in accordance with the terms of this Agreement and in lieu of Preferred Stock,
such number of validly issued, fully paid and non-assessable and freely tradable
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 Agreement to reflect any
events occurring in respect of such Principal Party after the date of such
consolidation, merger, sale or transfer; (B) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such consolidation,
merger, sale or transfer, all the obligations and duties of the Company pursuant
to this Agreement; (C) the term "Company" shall thereafter be deemed to refer to
such Principal Party; and (D) such Principal Party shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
shares of Common Stock in accordance with Section 9 hereof) in connection with
such consummation of any such transaction as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to the shares of its Common Stock thereafter deliverable upon
the exercise of the Rights; provided that, upon the subsequent occurrence of any


<PAGE>   20
                                                                              20


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

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

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

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

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

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

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

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

                  (d) In case the Principal Party has provision in any of its
authorized securities or in its certificate of incorporation or by-laws or other
instrument governing its corporate affairs, which provision would have the
effect of (i) causing such Principal Party to issue (other than to holders of
Rights pursuant to this Section 13), in connection with, or as a consequence of,
the consummation of a transaction referred to in this Section 13, shares of
Common Stock of such Principal Party at less than the then current market price
per share thereof (determined pursuant to Section 11(d) hereof) or securities
exercisable for, or convertible into, Common Stock 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 to the provisions of Section 13, then, in
such event, the Company hereby agrees with each holder of Rights that it shall
not consummate any such transaction unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing that the provision in question of such
Principal Party shall have been cancelled, waived or amended, or that the
authorized securities shall be redeemed, so that the applicable provision will
have no effect in connection with, or as a consequence of, the consummation of
the proposed transaction.

                  (e) The Company covenants and agrees that it shall not, at any
time after a Person first becomes an Acquiring Person enter into any transaction
of the type contemplated by clauses (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(a) hereof shall have received a distribution of Rights
previously owned by such Person or any of its Affiliates or Associates or (z)
the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

                  Section 14. Fractional Rights and Fractional Shares. (a) The
Company shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights (except prior to the
Distribution Date in accordance with Section 11(n) hereof). In lieu of such
fractional Rights, there shall be paid to the registered holders of the Right
Certificates with regard to which such fractional Rights would otherwise be
issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right. For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable. The closing price for any day shall be the last
sale price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Rights are not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the Company. If on any such date no such market maker is making a
market in the Rights, the fair value of the Rights on such date as determined in
good faith by the Board of Directors of the Company shall be used.

                  (b) The Company shall not be required to issue fractions of
Preferred Stock (other than fractions which are integral multiples of one
one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock). Interests in fractions of Preferred Stock in integral
multiples of one one-thousandth of a share of Preferred Stock may, at the
election of the Company, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Company and a depositary selected

<PAGE>   23
                                                                              23


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.

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

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

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


<PAGE>   24
                                                                              24


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

                  (b) after the Distribution Date, the Right Certificates are
           transferable only on the registry books of the Rights Agent if
           surrendered at the office or agency of the Rights Agent designated
           for such purpose, duly endorsed or accompanied by a proper instrument
           of transfer; and

                  (c) the Company and the Rights Agent may deem and treat the
           Person in whose name the Right Certificate (or, prior to the
           Distribution Date, the Common Stock certificate) is registered as the
           absolute owner thereof and of the Rights evidenced thereby
           (notwithstanding any notations of ownership or writing on the Right
           Certificates or the Common Stock certificate made by anyone other
           than the Company or the Rights Agent) for all purposes whatsoever,
           and neither the Company nor the Rights Agent shall be affected by any
           notice to the contrary.

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

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

                  (b) The Rights Agent shall be protected and shall incur no
liability for, or in respect of any action taken, suffered or omitted by it in
connection with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for the Preferred Stock or Common Stock or for other
securities of the Company, instrument of assignment or transfer, power of
attorney,

                                                                              25


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

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

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

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

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

                  (b) Whenever in the performance of its duties under this
           Agreement the Rights Agent shall deem it necessary or desirable that
           any fact or matter be proved or


<PAGE>   26
                                                                              26


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

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

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

                  (e) The Rights Agent shall not be under any responsibility in
           respect of the validity of this Agreement or the execution and
           delivery hereof (except the due execution hereof by the Rights Agent)
           or in respect of the validity or execution of any Right Certificate
           (except its countersignature thereof); nor shall it be responsible
           for any breach by the Company of any covenant or condition contained
           in this Agreement or in any Right Certificate; nor shall it be
           responsible for any change in the exercisability of the Rights
           (including the Rights becoming void pursuant to Section 11(a)(ii)
           hereof) or any adjustment in the terms of the Rights (including the
           manner, method or amount thereof) provided for in Sections 3, 11, 13,
           23 and 24, or the ascertaining of the existence of facts that would
           require any such change or adjustment (except with respect to the
           exercise of Rights evidenced by Right Certificates after receipt of a
           certificate furnished pursuant to Section 12, describing such change
           or adjustment); nor shall it by any act hereunder be deemed to make
           any representation or warranty as to the authorization or reservation
           of any shares of Preferred Stock or other securities to be issued
           pursuant to this Agreement or any Right Certificate or as to whether
           any shares of Preferred Stock or other securities will, when issued,
           be validly authorized and issued, fully paid and nonassessable.

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

                  (g) The Rights Agent is hereby authorized and directed to
           accept instructions with respect to the performance of its duties
           hereunder from any person reasonably believed by the Rights Agent to
           be one of the Chairman of the Board of Directors, the President, the
           Chief Financial Officer or the Secretary of the Company, and to apply
           to such officers for advice or instructions in connection with its
           duties, and it shall not be liable for any action taken or suffered
           by it in good faith in accordance with instructions of any such
           officer or for any delay in acting while waiting for those
           instructions. Any application by the Rights Agent for written
           instructions from the Company may, at the option of the Rights Agent,
           set forth in writing any action proposed to be taken or omitted by
           the Rights Agent under this


<PAGE>   27
                                                                              27

           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 though it were not Rights Agent under this
           Agreement. Nothing herein shall preclude the Rights Agent from acting
           in any other capacity for the Company or for any other legal entity.

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

                  (j) If, with respect to any Rights Certificate surrendered to
           the Rights Agent for exercise or transfer, the certificate contained
           in the form of assignment or the form of election to purchase set
           forth on the reverse thereof, as the case may be, has not been
           completed to certify the holder is not an Acquiring Person (or an
           Affiliate or Associate thereof), the Rights Agent shall not take any
           further action with respect to such requested exercise or transfer
           without first consulting with the Company.

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Stock or Preferred Stock by registered or certified
mail, and, following the Distribution Date, to the holders of the Right
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor Rights Agent upon 30 days' notice in writing, mailed to the Rights
Agent or successor Rights Agent, as the case may be, and to each transfer agent
of the Common Stock or Preferred Stock by registered or certified mail, and,
following the Distribution Date, to the holders of the Right Certificates by
first-class mail. If the Rights Agent shall resign or be removed or shall
otherwise become incapable of acting, the Company shall appoint a successor to
the Rights Agent. If the Company shall fail to make such appointment within a
period of 30 days after giving notice of such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Rights


<PAGE>   28

                                                                              28


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
holders of the Right Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

                  Section 22. Issuance of New Right Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such forms as may be approved by its Board of Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other securities or property purchasable under the Right
Certificates made in accordance with the provisions of this Agreement. In
addition, in connection with the issuance or sale of Common Stock following the
Distribution Date and prior to the earlier of the Redemption Date and the Final
Expiration Date, the Company may with respect to shares of Common Stock so
issued or sold pursuant to (i) the exercise of stock options, (ii) under any
employee plan or arrangement, (iii) upon the exercise, conversion or exchange of
securities, notes or debentures issued by the Company or (iv) a contractual
obligation of the Company in each case existing prior to the Distribution Date,
issue Rights Certificates representing the appropriate number of Rights in
connection with such issuance or sale.

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


<PAGE>   29
                                                                              29


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

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


<PAGE>   30
                                                                              30


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

                  (c) The Company may at its option and, in the event that there
shall not be sufficient shares of Common Stock issued but not outstanding or
authorized but unissued to permit an exchange of Rights as contemplated in
accordance with this Section 24, the Company may, in its discretion, take such
action as may be necessary to authorize additional shares of Common Stock for
issuance upon exchange of the Rights. In the event that the Company shall
determine not to take such action or shall, after good faith effort, be unable
to take such action as may be necessary to authorize such additional shares of
Common Stock, 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 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 of rights or warrants, or the date on which such
liquidation, dissolution or winding up is to take place and the date of
participation therein by the holders of the Common Stock and/or Preferred Stock,
if any such date is to be fixed, and such notice shall be so given in the case
of any action covered by clause (i) or (ii) above at least 10 days prior to the
record date for determining holders of the Preferred Stock for purposes of such
action, and in the case of any such other action, at least 10 days prior to the
date of the taking of

such proposed action or the date of participation therein by the holders of the
Common Stock and/or Preferred Stock, whichever shall be the earlier.

give to each holder of a Right Certificate (or if occurring prior to the
Distribution Date, the holders of the Common Stock) in accordance with Section
26 hereof, a notice of the occurrence of such event, which notice shall describe
such event and the consequences of such event to holders of Rights under Section
11(a)(ii) and Section 13 hereof.

                              ROHM AND HAAS COMPANY

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

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

                  Rohm and Haas Company, a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Company"), hereby certifies that the following resolution was duly adopted
by the Board of Directors of the Company as required by Section 151 of the
General Corporation Law of the State of Delaware at a meeting duly called and
held on October 19, 2000.

                  RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of the Company (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Company's
Certificate of Incorporation, as amended to date (hereinafter called the
"Certificate of Incorporation"), the Board of Directors hereby creates a series
of Preferred Stock, par value $1.00 per share, of the Company and hereby states
the designation and number of shares, and fixes the relative rights, powers and
preferences thereof, and the limitations thereof, as follows:

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" (the
"Series A Preferred Stock") and the number of shares constituting the Series A
Preferred Stock shall be 275,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Company
convertible into Series A Preferred Stock.


<PAGE>   36

                  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 $2.50 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, 1,000 times the aggregate per share amount
of all cash dividends, and 1,000 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 November 3, 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 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 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



                                      A-2
<PAGE>   37


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 1,000 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 November 3, 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.

                  Section 4. Certain Restrictions.(A) Whenever quarterly
dividends or other dividends or distributions payable on the Series A Preferred
Stock as provided in Section 2 are in arrears, thereafter and until all accrued
and unpaid dividends and distributions, whether or not earned or declared, on
shares of Series A Preferred Stock outstanding shall have been paid in full, the
Company shall not:

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



                                      A-3
<PAGE>   38

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

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

                          (iv) redeem or purchase or otherwise acquire for
                  consideration any shares of Series A Preferred Stock, or any
                  shares of stock ranking on a parity (either as to dividends or
                  upon liquidation, dissolution or winding up) with the Series A
                  Preferred Stock, except in accordance with a purchase offer
                  made in writing or by publication (as determined by the Board
                  of 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 $1,000 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



                                      A-4
<PAGE>   39


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 1,000 times the aggregate amount to be distributed per share to holders
of shares of Common Stock, or (B) to the holders of shares of stock ranking on a
parity upon liquidation, dissolution or winding up with the Series A Preferred
Stock, except distributions made ratably on the Series A Preferred Stock and all
such parity stock in proportion to the total amounts to which the holders of all
such shares are entitled upon such liquidation, dissolution or winding up. In
the event, however, that there are not sufficient assets available to permit
payment in full of the Series A liquidation preference and the liquidation
preferences of all other classes and series of stock of the Company, if any,
that rank on a parity with the Series A Preferred Stock in respect thereof, then
the assets available for such distribution shall be distributed ratably to the
holders of the Series A Preferred Stock and the holders of such parity shares in
the proportion to their respective liquidation preferences. In the event the
Company shall at any time after November 3, 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.

                  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 1,000 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 November 3, 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.

                  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.

                          SUMMARY OF RIGHTS TO PURCHASE

                            Shares of Preferred Stock

                  On October 19, 2000 the Board of Directors of Rohm and Haas
Company (the "Company") declared a dividend of one preferred share purchase
right (a "Right") for each outstanding share of common stock, par value $2.50
per share of the Company (the "Common Stock"). The dividend is payable on
November 3, 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 $1.00 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 October 26,
2000 as the same may be amended from time to time (the "Rights Agreement"),
between the Company and EquiServe Trust Company, NA, 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 by such Common Stock
certificate together with a copy of this Summary of Rights. Notwithstanding the
foregoing, the descendants of each of Otto Haas and his spouse, the spouses of
such descendants and any trusts and foundations established by any of them
(collectively, the "Haas Family") shall not be deemed to be or to become an
Acquiring Person unless and until such time as the Haas Family shall become the
beneficial owner of 35% or more of the outstanding Common Stock.

                  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




                                      C-1
<PAGE>   49


reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for shares of Common
Stock outstanding as of the Record Date, even without such notation or a copy of
this Summary of Rights, will also constitute the transfer of the Rights
associated with the shares of Common Stock represented by such certificate. As
soon as practicable following the Distribution Date, separate certificates
evidencing the Rights ("Right Certificates") will be mailed to holders of record
of the Common Stock as of the close of business on the Distribution Date and
such separate Right Certificates alone will evidence the Rights.

                  The Rights are not exercisable until the Distribution Date.
The Rights will expire on December 1, 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 $10 per share but will be entitled to an aggregate dividend of 1,000 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 $1,000 per
share (plus any accrued but unpaid dividends) but will be entitled to an
aggregate payment of 1,000 times the payment made per share of Common Stock.
Each share of Preferred Stock will have 1,000 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 1,000 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


                                      C-2
<PAGE>   50

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

                  In the event that, after a person or group has become an
Acquiring Person, the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold, proper provision will be made so that each holder of a Right
(other than Rights beneficially owned by an Acquiring Person or any affiliate or
associate of the Acquiring Person or certain other transferees which will have
become void) will thereafter have the right to receive, upon the exercise
thereof at the then current Purchase Price, that number of shares of common
stock of the person with whom the Company has engaged in the foregoing
transaction (or its parent), which 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 preceding 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 class or
series of the Company's preferred stock having similar rights, preferences and
privileges) 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 in any
manner. After the Rights are no longer redeemable, the Company may, except with
respect to the redemption price, amend the Rights in any manner that does not
adversely affect the interests of holders of the Rights.

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