                                RIGHTS AGREEMENT

     Rights Agreement, dated as of [________ __], 2004 (the "AGREEMENT"), by and
between Hospira, Inc., a Delaware corporation (the "COMPANY"), and EquiServe
Trust Company, N.A., a national banking association (the "RIGHTS AGENT").

                              W I T N E S S E T H:

     WHEREAS, the Board of Directors of the Company has authorized the issuance
of one Right in respect of, and to be issued together with, each share of common
stock, par value $0.01 per share, of the Company (the "COMMON STOCK") issued and
outstanding as of the close of business on [___________ __], 2004 (the "Record
Date"); and the Board of Directors of the Company has authorized the issuance of
one Right (as such number may hereinafter be adjusted pursuant to the provisions
of SECTION 11(p) hereof) for each share of Common Stock of the Company issued
(whether originally issued or delivered from the Company's treasury) between the
Record Date and the earlier of the Distribution Date (as hereinafter defined)
and the Expiration Date (as hereinafter defined), and, in certain circumstances
provided for in SECTION 22 hereof, after the Distribution Date, each Right
initially representing the right to purchase one Fractional Share (as
hereinafter defined) of Series A Junior Participating Preferred Stock of the
Company, upon the terms and subject to the conditions hereinafter set forth (the
"RIGHTS").

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

          Section 1. CERTAIN DEFINITIONS. For purposes of this Agreement, the
following terms shall have the meanings indicated:

     "ACQUIRING PERSON" shall mean any Person who or which, together with all
Affiliates and Associates of such Person, shall be the Beneficial Owner of 15%
or more of the shares of Common Stock then outstanding, but shall not include
any Exempt Person; PROVIDED, HOWEVER, that a Person shall not be or become an
Acquiring Person if such Person, together with its Affiliates and Associates,
shall become the Beneficial Owner of 15% or more of the shares of Common Stock
then outstanding solely as a result of a reduction in the number of shares of
Common Stock outstanding due to the repurchase of Common Stock by the Company
unless and until such time as such Person or any Affiliate or Associate of such
Person shall purchase or otherwise become the Beneficial Owner of additional
shares of Common Stock constituting 1% or more of the then-outstanding shares of
Common Stock or any other Person (or Persons) who is (or collectively are) the
Beneficial Owner of shares of Common Stock constituting 1% or more of the
then-outstanding shares of Common Stock shall become an Affiliate or Associate
of such Person; and PROVIDED, FURTHER, that if the Board of Directors, with the
concurrence of a majority of the members of the Board of Directors who are not
such Person or representatives, nominees, Affiliates or Associates of such
Person, determines in good faith that a Person that would otherwise be an
"Acquiring Person" has become such inadvertently (including, without limitation,
because (1) 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 (2) 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 Agreement) and

                                        1
<Page>

without any intention of changing or influencing control of the Company, and if
such Person as promptly as practicable divested or divests 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.

     "ADJUSTMENT SHARES" shall have the meaning set forth in SECTION 11(a)(ii)

any class of equity securities, (2) any trust or other estate in which such

such Person, or any relative of such spouse, who has the same home as such
Person.

     under the Exchange Act as in effect on the date of this Agreement) or
     otherwise has the right to vote or dispose of, including pursuant to any
     agreement, arrangement or understanding (whether or not in writing);
     PROVIDED, HOWEVER, that a Person shall not be deemed the "Beneficial Owner"
     of, or to "beneficially own," any security under this subparagraph (i) as a
     result of an agreement, arrangement or understanding to vote such security
     if such agreement, arrangement or understanding: (A) arises solely from a
     revocable proxy or consent given in response to a proxy or consent
     solicitation that is not exempted by Rule 14a-2(b)(2) of the General Rules
     and Regulations under the Exchange Act as in effect on the date of this
     Agreement and that is made pursuant to, and in accordance with, the
     applicable provisions of the General Rules and Regulations under the
     Exchange Act and (B) is not then reportable by such Person on Schedule 13D
     or 13G under the Exchange Act (or any comparable or successor report);

          (ii)    that such Person or any of such Person's Affiliates or
     Associates, directly or indirectly, has the right or obligation to acquire
     (whether such right or obligation is exercisable or effective immediately
     or only after the passage of time or the occurrence of an event) pursuant
     to any agreement, arrangement or understanding (whether or not in writing)
     or upon the exercise of conversion rights, exchange rights, other rights,
     warrants or options, or otherwise; PROVIDED, HOWEVER, that a Person shall
     not be deemed the "Beneficial Owner" of, or to "beneficially own," (A)

     Person or any of such Person's Affiliates or Associates until such tendered

     SECTION 22 hereof (the "ORIGINAL RIGHTS") or pursuant to SECTION 11(i) or
     (p) hereof in connection with an adjustment made with respect to any
     Original Rights; or

     any other Person (or any Affiliate or Associate thereof) with which

     agreement, arrangement or understanding (whether or not in writing) for the
     purpose of acquiring, holding, disposing (except pursuant to a tender of

     securities being accepted for purchase or exchange as described in the
     proviso to subparagraph (ii) of this definition) or voting (except pursuant
     to a revocable proxy or consent as described in the proviso to subparagraph

PROVIDED, HOWEVER, that nothing in this definition shall cause a Person engaged
in business as an underwriter of securities to be the "Beneficial Owner" of, or
to "beneficially own," any securities acquired through such Person's
participation in good faith in a firm commitment underwriting (including,
without limitation, securities acquired pursuant to stabilizing transactions to

offering) until the expiration of forty days after the date of such acquisition.

that are issued (whether originally issued or delivered from the Company's
treasury) after the Record Date but prior to the earlier of the Distribution

     amended (the "RIGHTS AGREEMENT"), the terms of which are hereby
     incorporated herein by reference and a copy of which is on file at the
     principal offices of the Company. Under certain circumstances, as set forth
     in the Rights Agreement, such Rights may be redeemed, may be exchanged, may
     expire or may be evidenced by separate certificates and will no longer be
     evidenced by this certificate. The Company or the Rights Agent will mail to
     the holder of this certificate a copy of the Rights Agreement, as in effect
     on the date of mailing, without charge promptly after receipt of a written
     request therefor. UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS
     AGREEMENT, RIGHTS BENEFICIALLY OWNED BY OR TRANSFERRED TO ANY PERSON WHO
     IS, WAS OR BECOMES AN ACQUIRING PERSON OR AN AFFILIATE OR ASSOCIATE THEREOF
     (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), 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
earlier of the Distribution Date or the Expiration Date, the Rights associated
with the Common Stock represented by such certificates shall be evidenced by
such certificates alone, and registered holders of Common Stock shall also be
the registered holders of the associated Rights, and the transfer of any of such
certificates shall also constitute the transfer of the Rights associated with
the Common Stock represented by such certificates.

          Section 4. FORM OF RIGHTS CERTIFICATES.

          (a) The Rights Certificates (and the forms of election to purchase and
of assignment to be printed on the reverse thereof), when, as and if issued,
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 any stock exchange or quotation system
on which the Rights may from time to time be listed or quoted, or to conform to
usage. Subject to the provisions of SECTION 11 and SECTION 22 hereof, the Rights
Certificates, whenever issued, shall be dated as of the Record Date and on their
face shall entitle the holders thereof to purchase such number of Fractional
Shares of Preferred Stock as shall be set forth therein at the price set forth
therein (such exercise price per Fractional Share (or, as set forth in this
Agreement, for other securities), the "PURCHASE PRICE"), but the amount and type
of securities purchasable upon the exercise of each Right and the Purchase Price
thereof shall be subject to adjustment as provided herein.

          (b) Any Rights Certificate issued pursuant to SECTION 3(a) or SECTION
22 hereof that represents Rights beneficially owned by a Person described in the
first sentence of SECTION

                                        8
<Page>

7(e), and any Rights Certificate issued pursuant to SECTION 6 or SECTION 11
hereof upon transfer, exchange, replacement or adjustment of any such Rights,
shall contain (to the extent feasible) the following legend, modified as
applicable to apply to such Person:

     The Rights represented by this Rights Certificate are or were beneficially
     owned by a Person who was or became an Acquiring Person or an Affiliate or
     Associate of an Acquiring Person (as such terms are defined in the Rights
     Agreement). Accordingly, this Rights Certificate and the Rights represented
     hereby [will] [have] become null and void in the circumstances and with the
     effect specified in SECTION 7(e) of such Agreement.

The provisions of SECTION 7(e) of this Agreement shall be operative whether or
not the foregoing legend is contained on any such Rights Certificate. The
Company shall give notice to the Rights Agent promptly after it becomes aware of
the existence of any Acquiring Person or any Associate or Affiliate thereof.

          Section 5. COUNTERSIGNATURE AND REGISTRATION.

          (a) The Rights Certificates shall be executed on behalf of the Company
by its Chairman of the Board, its Chief Executive Officer, its President or any
Vice President, either manually or by facsimile signature, and shall have
affixed thereto the Company's seal or a facsimile thereof, which shall be
attested by the Secretary or an Assistant Secretary of the Company, either
manually or by facsimile signature. The Rights Certificates shall be
countersigned by the Rights Agent, either manually or by facsimile signature,
and shall not be valid for any purpose unless so countersigned. In case any
officer of the Company who shall have signed any of the Rights Certificates
shall cease to be such officer of the Company before countersignature by the
Rights Agent and issuance and delivery by the Company, such Rights 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 Rights Certificates had not ceased to be such officer of the Company; and
any Rights Certificate may be signed on behalf of the Company by any person who,
at the actual date of the execution of such Rights Certificate, shall be a
proper officer of the Company to sign such Rights Certificate, although at the
date of the execution of this Rights Agreement any such person was not such an
officer.

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

          Section 6. TRANSFER, SPLIT-UP, COMBINATION AND EXCHANGE OF RIGHTS
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

          (a) Subject to the provisions of SECTION 4(b), SECTION 7(e), SECTION
13(d), SECTION 14 and SECTION 24 hereof, at any time after the close of business
on the Distribution Date, and at or prior to the close of business on the
Expiration Date, any Rights Certificate or Rights

                                        9
<Page>

Certificates may be transferred, split up, combined or exchanged for another
Rights Certificate or Rights Certificates, entitling the registered holder to
purchase a like number of Fractional Shares of Preferred Stock (or, following a
Triggering Event, Common Stock, other securities, cash or other assets, as the
case may be) as the Rights Certificate or Rights Certificates surrendered then
entitled such holder (or former holder in the case of a transfer) to purchase.
Any registered holder desiring to transfer, split up, combine or exchange any
Rights Certificate or Rights Certificates shall make such request in writing
delivered to the Rights Agent, and shall surrender the Rights Certificate or
Rights Certificates to be transferred, split up, combined or exchanged at the
principal office or offices of the Rights Agent designated for such purpose.
Neither the Rights Agent nor the Company shall be obligated to take any action
whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and signed the
certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) thereof or of the
Affiliates or Associates thereof as the Company shall reasonably request.
Thereupon the Rights Agent shall, subject to SECTION 4(b), SECTION 7(e), SECTION
13(d), SECTION 14 and SECTION 24 hereof, countersign and deliver to the Person
entitled thereto a Rights Certificate or Rights Certificates, as the case may
be, as so requested. The Company may require payment by the holder of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split-up, combination or exchange of Rights
Certificates.

          (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Rights Certificate, and, in case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to them, and reimbursement to the Company
and the Rights Agent of all reasonable expenses incidental thereto, and upon
surrender to the Rights Agent and cancellation of the Rights Certificate if
mutilated, the Company will, subject to SECTION 4(b), SECTION 7(e), SECTION
13(d), SECTION 14 and SECTION 24, execute and deliver a new Rights Certificate
of like tenor to the Rights Agent for countersignature and delivery to the
registered owner in lieu of the Rights Certificate so lost, stolen, destroyed or
mutilated.

          Section 7. EXERCISE OF RIGHTS; PURCHASE PRICE.

          (a) Subject to SECTION 7(e) hereof, the registered holder of any
Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in SECTION 9(c), SECTION 11(a)(iii) and SECTION 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly completed and executed, to the
Rights Agent at the principal office or offices of the Rights Agent designated
for such purpose, together with payment of the aggregate Purchase Price with
respect to the total number of Fractional Shares of Preferred Stock (or other
securities, cash or other assets, as the case may be) as to which such
surrendered Rights are then exercisable, at or prior to the Expiration Date.

          (b) The Purchase Price for each Fractional Share of Preferred Stock
pursuant to the exercise of a Right shall initially be $[________], and shall be
subject to adjustment from

                                       10
<Page>

time to time as provided in SECTIONS 11 and 13(a) hereof and shall be payable in
accordance with paragraph (c) below.

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase and the certificate on the reverse
side thereof duly executed, accompanied by payment, with respect to each Right
so exercised, of the Purchase Price per Fractional Share of Preferred Stock (or
other shares, securities, cash or other assets, as the case may be) to be
purchased as set forth below and an amount equal to any applicable transfer tax,
the Rights Agent shall, subject to SECTION 20(k) hereof, thereupon promptly
(i)(A) requisition from any transfer agent of the shares of Preferred Stock (or
make available, if the Rights Agent is the transfer agent for such shares)
certificates for the total number of Fractional Shares of Preferred Stock to be
purchased, and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company, in its sole discretion,
shall have elected to deposit the shares of Preferred Stock issuable upon
exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing interests in such number of
Fractional Shares of Preferred Stock as are to be purchased (in which case
certificates for the shares of Preferred Stock represented by such receipts
shall be deposited by the transfer agent with the depositary agent) and the
Company will direct the depositary agent to comply with such request, (ii)
requisition from the Company the amount of cash, if any, to be paid in lieu of
fractional shares in accordance with SECTION 14 hereof, (iii) 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 Rights Certificate, registered
in such name or names as may be designated by such holder and (iv) after receipt
thereof, deliver such cash, if any, to or upon the order of the registered
holder of such Rights Certificate. The payment of the Purchase Price (as such
amount may be reduced pursuant to SECTION 11(a)(iii) hereof) may be made in cash
or by certified check, cashier's or official bank check or bank draft payable to
the order of the Company or the Rights Agent. In the event that the Company is
obligated to issue other securities (including Common Stock) of the Company, pay
cash and/or distribute other property pursuant to SECTION 11(a) or SECTION 13(a)
hereof, the Company will make all arrangements necessary so that such other
securities, cash and/or other property are available for distribution by the
Rights Agent, if and when appropriate. The Company reserves the right to require
prior to the occurrence of a Triggering Event that, upon exercise of Rights, a
number of Rights be exercised so that only whole shares of Preferred Stock would
be issued.

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

          (e) Notwithstanding anything in this Agreement to the contrary, from
and after the first occurrence of a Triggering Event, any Rights beneficially
owned by or transferred to (i) an Acquiring Person or an Associate or Affiliate
of an Acquiring Person other than any such Person that became such pursuant to a
Permitted Offer and the Board of Directors in good faith determines was not
involved in and did not cause or facilitate, directly or indirectly, such
Triggering Event, (ii) a direct or indirect transferee of such Rights from such
Acquiring Person

                                       11
<Page>

(or any such Associate or Affiliate) who becomes a transferee after such
Triggering Event or (iii) a direct or indirect transferee of such Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee prior to
or concurrently with such Triggering Event and receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from such Acquiring
Person (or such Affiliate or Associate) to holders of equity interests in such
Acquiring Person (or such Affiliate or Associate) or to any Person with whom
such Acquiring Person (or such Affiliate or Associate) has any continuing
agreement, arrangement or understanding regarding the transferred Rights or (B)
a transfer that the Board of Directors of the Company determines is part of a
plan, arrangement or understanding that has as a primary purpose or effect the
avoidance of this SECTION 7(e), shall become null and void without any further
action, no holder of such Rights shall have any rights whatsoever with respect
to such Rights, whether under any provision of this Agreement or otherwise, and
such Rights shall not be transferable. The Company shall use all reasonable
efforts to ensure that the provisions of this SECTION 7(e) and SECTION 4(b)
hereof are complied with, but shall have no liability to any holder of Rights
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.

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

          Section 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All
Rights Certificates surrendered for the purpose of exercise, transfer, split-up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
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 Rights Certificate purchased or acquired by the Company
otherwise than upon the exercise thereof. The Rights Agent shall deliver all
canceled Rights Certificates to the Company, or shall, at the written request of
the Company, destroy such canceled Rights Certificates, and in such case shall
deliver a certificate of destruction thereof to the Company.

          Section 9. RESERVATION AND AVAILABILITY OF CAPITAL STOCK.

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

                                       12
<Page>

          (b) So long as any shares of Preferred Stock (and, following the
occurrence of a Triggering Event, Common Stock and/or other securities) issuable
and deliverable upon the exercise of the Rights are listed on any national
securities exchange or quoted on any trading 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 on such
exchange, or quoted on such system, upon official notice of issuance upon such
exercise. Following the occurrence of a Triggering Event, the Company will use
its best efforts to list (or continue the listing of) the Rights and the
securities issuable and deliverable upon the exercise of the Rights on one or
more national securities exchanges or to cause the Rights and the securities
purchasable upon exercise of the Rights to be reported by NASDAQ or such other
transaction reporting system then in use.

          (c) The Company shall use its best efforts to (i) prepare and file, as
soon as practicable following the first occurrence of a Flip-In Event or, if
applicable, as soon as practicable following the earliest date after the first
occurrence of a Flip-In Event on which the consideration to be delivered by the
Company upon exercise of the Rights has been determined pursuant to this
Agreement (including in accordance with SECTION 11(a)(iii) hereof), a
registration statement on an appropriate form under the Securities Act with
respect to the securities purchasable upon exercise of the Rights, (ii) cause
such registration statement to become effective as soon as practicable after
such filing, and (iii) cause such registration statement to remain effective
(with a prospectus at all times meeting the requirements of the Securities Act)
until the earlier of (A) the date as of which the Rights are no longer
exercisable for such securities and (B) the Expiration Date. The Company will
also take such action as may be appropriate under, or to ensure compliance with,
the securities or "blue sky" laws of the various states in connection with the
exercisability of the Rights. The Company may temporarily suspend, for a period
of time not to exceed 90 days after the date set forth in clause (i) of the
first sentence of this SECTION 9(c), the exercisability of the Rights in order
to prepare and file such registration statement and permit it to become
effective. In addition, if the Company shall determine that the Securities Act
requires an effective registration statement under the Securities Act following
the Distribution Date, the Company may temporarily suspend the exercisability of
the Rights until such time as such a registration statement has been declared
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 if the
requisite qualification in such jurisdiction shall not have been obtained, the
exercise thereof shall not be permitted under applicable law or any required
registration statement shall not have been declared effective.

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

          (e) The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and charges that may be
payable in respect of

                                       13
<Page>

the issuance or delivery of the Rights Certificates and of any certificates for
a number of Fractional Shares of Preferred Stock (or Common Stock and/or other
securities, as the case may be) upon the exercise of Rights. The Company shall
not, however, be required to pay any transfer tax that may be payable in respect
of any transfer or delivery of Rights Certificates to a Person other than, or
the issuance or delivery of a number of Fractional Shares of Preferred Stock (or
Common Stock and/or other securities, as the case may be) in respect of a name
other than that of, the registered holder of the Rights Certificates evidencing
Rights surrendered for exercise or to issue or deliver any certificates for a
number of Fractional Shares of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until such tax shall have been paid (any
such tax being payable by the holder of such Rights Certificate at the time of
surrender) or until it has been established to the Company's satisfaction that
no such tax is due.

          Section 10. PREFERRED STOCK RECORD DATE. Each Person in whose name any
certificate for a number of Fractional Shares of Preferred Stock (or Common
Stock and/or other securities, as the case may be) is issued upon the exercise
of Rights shall for all purposes be deemed to have become the holder of record
of such shares (fractional or otherwise) of Preferred Stock (or Common Stock
and/or other securities, as the case may be) represented thereby on, and such
certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; PROVIDED, HOWEVER, that if the
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares (fractional or otherwise) on, and such certificate shall be
dated, the next succeeding Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are open. Prior to the exercise of the Rights evidenced thereby, the holder of a
Rights Certificate, as such, shall not be entitled to any rights of a
stockholder of the Company with respect to shares for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

          Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR
NUMBER OF RIGHTS. The Purchase Price, the number and kind of shares or other
securities subject to purchase 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 (A) declare
     a dividend on the outstanding shares of Preferred Stock payable in shares
     of Preferred Stock, (B) subdivide the outstanding shares of Preferred
     Stock, (C) combine the outstanding shares of Preferred Stock into a smaller
     number of shares or (D) otherwise reclassify the outstanding shares of
     Preferred Stock (including any such reclassification in connection with a
     consolidation or merger in which the Company is the continuing or surviving
     corporation), except as otherwise provided in this SECTION 11(a) and
     SECTION 7(e) hereof, the Purchase Price in effect at the time of the record
     date for such dividend or of the effective date of such subdivision,
     combination or reclassification, and the number and

                                       14
<Page>

     kind of shares of Preferred Stock or capital stock, as the case may be,
     issuable on such date, shall be proportionately adjusted so that the holder
     of any Right exercised after such time shall be entitled to receive, upon
     payment of the Purchase Price then in effect, the aggregate number and kind
     of shares of Preferred Stock or capital stock, as the case may be, which,
     if such Right had been exercised immediately prior to such date and at a
     time when the Preferred Stock transfer books of the Company were open, he
     would have owned upon such exercise and been entitled to receive by virtue
     of such dividend, subdivision, combination or reclassification. If an event
     occurs that would require an adjustment under both this SECTION 11(a)(i)
     and SECTION 11(a)(ii) hereof, the adjustment provided for in this SECTION
     11(a)(i) shall be in addition to, and shall be made prior to, any
     adjustment required pursuant to SECTION 11(a)(ii) hereof.

                  (ii) Subject to SECTIONS 23 and 24 of this Agreement, in the
     event any Person shall, at any time after the Record Date, become an
     Acquiring Person, unless the event causing such Person to become an
     Acquiring Person is (1) a Flip-Over Event or (2) an acquisition of shares
     of Common Stock pursuant to a Permitted Offer (provided that this clause
     (2) shall cease to apply if such Acquiring Person thereafter becomes the
     Beneficial Owner of any additional shares of Common Stock other than
     pursuant to such Permitted Offer or a transaction set forth in SECTION
     13(a) or 13(d) hereof), then, (x) the Purchase Price shall be adjusted to
     be the Purchase Price immediately prior to the first occurrence of a
     Flip-In Event multiplied by the number of Fractional Shares of Preferred
     Stock for which a Right was exercisable immediately prior to such first
     occurrence and (y) each holder of a Right (except as provided below in
     SECTION 11(a)(iii) and in SECTION 7(e) hereof) shall thereafter have the
     right to receive, upon exercise thereof at a price equal to the Purchase
     Price in accordance with the terms of this Agreement, in lieu of shares of
     Preferred Stock, such number of shares of Common Stock of the Company as
     shall equal the result obtained by dividing the Purchase Price by 50% of
     the Current Market Price per share of Common Stock on the date of such
     first occurrence (such number of shares, the "ADJUSTMENT SHARES"); PROVIDED
     that the Purchase Price and the number of Adjustment Shares shall be
     further adjusted as provided in this Agreement to reflect any events
     occurring after the date of such first occurrence.

                  (iii) In the event that the number of shares of Common Stock
     that are authorized by the Company's certificate of incorporation but not
     outstanding or reserved for issuance for purposes other than upon exercise
     of the Rights is not sufficient to permit the exercise in full of the
     Rights in accordance with the foregoing subparagraph (ii) of this SECTION
     11(a), the Company shall, to the extent permitted by applicable law and
     regulation, (A) determine the excess of (1) the value of the Adjustment
     Shares issuable upon the exercise of a Right (computed using the Current
     Market Price used to determine the number of Adjustment Shares) (the
     "CURRENT VALUE") over (2) the Purchase Price (such excess is herein
     referred to as the "SPREAD"), and (B) with respect to each Right, make
     adequate provision to substitute for the Adjustment Shares, upon the
     exercise of the Rights and payment of the applicable Purchase Price, (1)
     cash, (2) a reduction in the Purchase Price, (3) Common Stock or other
     equity securities of the Company (including, without limitation, shares, or
     units of shares, of preferred stock (including, without limitation, the
     Preferred Stock) that the Board of Directors of the Company has

                                       15
<Page>

     determined to have the same value as shares of Common Stock (such shares of
     preferred stock are herein referred to as "COMMON STOCK EQUIVALENTS")), (4)
     debt securities of the Company, (5) other assets or (6) any combination of
     the foregoing, having an aggregate value equal to the Current Value, where
     such aggregate value has been determined by the Board of Directors of the
     Company based upon the advice of a nationally recognized investment banking
     firm selected by the Board of Directors of the Company; PROVIDED, HOWEVER,
     if the Company shall not have made adequate provision to deliver value
     pursuant to clause (B) above within 30 days following the later of (x) the
     first occurrence of a Flip-In Event and (y) the date on which the Company's
     right of redemption pursuant to SECTION 23(a) expires (the later of (x) and
     (y) being referred to herein as the "FLIP-IN TRIGGER DATE"), then the
     Company shall be obligated to deliver, upon the surrender for exercise of a
     Right and without requiring payment of the Purchase Price, shares of Common
     Stock (to the extent available) and then, if necessary, cash, which shares
     and/or cash have an aggregate value equal to the Spread. If the Board of
     Directors of the Company shall determine in good faith that it is likely
     that sufficient additional shares of Common Stock could be authorized for
     issuance upon exercise in full of the Rights, the 30-day period set forth
     above may be extended to the extent necessary, but not more than 90 days
     after the Flip-In Trigger Date, in order that the Company may seek
     stockholder approval for the authorization of such additional shares (such
     period, as it may be extended, the "SUBSTITUTION PERIOD"). To the extent
     that the Company or the Board of Directors determines that some action need
     be taken pursuant to the first and/or second sentences of this SECTION
     11(a)(iii), the Company (x) shall provide, subject to SECTION 7(e) hereof,
     that such action shall apply uniformly to all outstanding Rights, and (y)
     may suspend the exercisability of the Rights until the expiration of the
     Substitution Period in order to seek any authorization of additional shares
     and/or to decide the appropriate form of distribution to be made pursuant
     to such first sentence and to determine the value thereof. In the event of
     any such suspension, the Company shall issue a public announcement stating
     that the exercisability of the Rights has been temporarily suspended, as
     well as a public announcement at such time as the suspension is no longer
     in effect. For purposes of this SECTION 11(a)(iii), the value of the Common
     Stock shall be the Current Market Price per share of the Common Stock on
     the Flip-In Trigger Date and the value of any Common Stock Equivalent shall
     be deemed to have the same value as the Common Stock on such date.

          (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Stock entitling them to
subscribe for or purchase (for a period expiring within 45 calendar days after
such record date) Preferred Stock (or shares having substantially the same
rights, privileges and preferences as the shares of Preferred Stock ("EQUIVALENT
PREFERRED STOCK")) or securities convertible into Preferred Stock or Equivalent
Preferred Stock at a price per share of Preferred Stock or per share of
Equivalent Preferred Stock (or having a conversion price per share, if a
security convertible into Preferred Stock or Equivalent Preferred Stock) less
than the Current Market Price per share of Preferred Stock on such record date,
the Purchase Price to be in effect after such record date shall be determined by
multiplying the Purchase Price in effect immediately prior to such record date
by a fraction, the numerator of which shall be the number of shares of Preferred
Stock outstanding on such record date, plus the number of shares of Preferred
Stock that the aggregate offering price of the total

                                       16
<Page>

number of shares of Preferred Stock and/or Equivalent Preferred Stock so to be
offered (and/or the aggregate initial conversion price of the convertible
securities so to be offered) would purchase at such Current Market Price, and
the denominator of which shall be the number of shares of Preferred Stock
outstanding on such record date, plus the number of additional shares of
Preferred Stock and/or Equivalent Preferred Stock to be offered for subscription
or purchase (or into which the convertible securities so to be offered are
initially convertible). In case such subscription price may be paid by delivery
of consideration, part or all of which may be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and the
holders of the Rights. Shares of Preferred Stock owned by or held for the
account of the Company shall not be deemed outstanding for the purpose of any
such computation. Such adjustment shall be made successively whenever such a
record date is fixed, and in the event that such rights or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price that would
then be in effect if such record date had not been fixed.

          (c) In case the Company shall fix a record date for a distribution to
all holders of Preferred Stock (including any such distribution made in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation) of evidences of indebtedness, cash (other than a
regular quarterly cash dividend out of the earnings or retained earnings of the
Company), assets (other than a dividend payable in Preferred Stock, but
including any dividend payable in stock other than Preferred Stock) or
subscription rights or warrants (excluding those referred to in SECTION 11(b)
hereof), the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the Current Market
Price per share of Preferred Stock on such record date, less the fair market
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent and shall be binding on the Rights Agent) of the portion of the cash,
assets or evidences of indebtedness so to be distributed or of such subscription
rights or warrants applicable to a share of Preferred Stock and the denominator
of which shall be such Current Market Price per share of Preferred Stock. Such
adjustments shall be made successively whenever such a record date is fixed, and
in the event that such distribution is not so made, the Purchase Price shall be
adjusted to be the Purchase Price that would have been in effect if such record
date had not been fixed.

          (d) (i) For the purpose of any computation hereunder, other than
     computations made pursuant to SECTION 11(a)(iii) hereof, the "CURRENT
     MARKET PRICE" per share of Common Stock of a Person on any date shall be
     deemed to be the average of the daily Closing Prices per share of such
     Common Stock for the 30 consecutive Trading Days immediately prior to such
     date, and for purposes of computations made pursuant to SECTION 11(a)(iii)
     hereof, the "CURRENT MARKET PRICE" per share of Common Stock on any date
     shall be deemed to be the average of the daily Closing Prices per share of
     such Common Stock for the 10 consecutive Trading Days immediately following
     such date; PROVIDED, HOWEVER, that in the event that the Current Market
     Price per share of Common Stock is determined during a period following the
     announcement of (A) a dividend or distribution on such Common Stock other
     than a regular quarterly cash dividend or the

                                       17
<Page>

     dividend of the Rights, or (B) any subdivision, combination or
     reclassification of such Common Stock, and the ex-dividend date for such
     dividend or distribution, or the record date for such subdivision,
     combination or reclassification, shall not have occurred prior to the
     commencement of the requisite 30 Trading Day or 10 Trading Day period, as
     set forth above, then, and in each such case, the Current Market Price
     shall be properly adjusted to take into account ex-dividend trading. If the
     Common Stock is not publicly held or not so listed or traded, "CURRENT
     MARKET PRICE" per share shall mean the fair value per share as determined
     in good faith by the Board of Directors of the Company, whose determination
     shall be described in a statement filed with the Rights Agent and shall be
     conclusive for all purposes.

                  (ii) For the purpose of any computation hereunder, the
     "CURRENT MARKET PRICE" per share (or Fractional Share) of Preferred Stock
     shall be determined in the same manner as set forth above for the Common
     Stock in clause (i) of this SECTION 11(d) (other than the last sentence
     thereof). If the Current Market Price per share (or Fractional Share) of
     Preferred Stock cannot be determined in the manner provided above or if the
     Preferred Stock is not publicly held or listed or traded in a manner
     described in clause (i) of this SECTION 11(d), the "CURRENT MARKET PRICE"
     per share of Preferred Stock shall be conclusively deemed to be an amount
     equal to 100 (as such number may be appropriately adjusted for such events
     as stock splits, stock dividends and recapitalizations with respect to the
     Common Stock occurring after the date of this Agreement) multiplied by the
     Current Market Price per share of the Common Stock. If neither the Common
     Stock nor the Preferred Stock is publicly held or so listed or traded,
     Current Market Price per share of the Preferred Stock shall mean the fair
     value per share as determined in good faith by the Board of Directors of
     the Company, whose determination shall be described in a statement filed
     with the Rights Agent and shall be conclusive for all purposes. For all
     purposes of this Agreement, the Current Market Price of a Fractional Share
     of Preferred Stock shall be equal to the Current Market Price of one share
     of Preferred Stock divided by 100.

          (e) Anything herein to the contrary notwithstanding, no adjustment in
the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least 1% in the Purchase Price; PROVIDED, HOWEVER,
that any adjustments that by reason of this SECTION 11(e) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this SECTION 11 shall be made to the nearest
cent or to the nearest ten-thousandth of a share of Common Stock or other share
or to the nearest ten-thousandth of a Fractional Share of Preferred Stock, as
the case may be. Notwithstanding the first sentence of this SECTION 11(e), any
adjustment required by this SECTION 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which mandates such
adjustment or (ii) the Expiration Date.

          (f) If as a result of an adjustment made pursuant to SECTION 11(a) or
SECTION 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive in respect of such Right any shares of capital stock other
than Preferred Stock, thereafter the number of such other shares so receivable
upon exercise of any Right and the Purchase Price thereof shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as

                                       18
<Page>

practicable to the provisions with respect to the Preferred Stock contained in
SECTIONS 11(a), (b), (c), (e), (f), (g), (h), (i), (j), (k) and (m) hereof, 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 Fractional Shares 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 Fractional Shares of
Preferred Stock (calculated to the nearest one ten-thousandth of a Fractional
Share) obtained by (i) multiplying (x) the number of Fractional Shares of
Preferred Stock covered by a Right immediately prior to this adjustment by (y)
the Purchase Price in effect immediately prior to such adjustment of the
Purchase Price, and (ii) dividing the product so obtained by the Purchase Price
in effect immediately after such adjustment of the Purchase Price.

          (i) The Company may elect, on or after the date of any adjustment of
the Purchase Price, to adjust the number of Rights in lieu of any adjustment in
the number of Fractional Shares of Preferred Stock purchasable upon the exercise
of a Right. Each of the Rights outstanding after the adjustment in the number of
Rights shall be exercisable for the number of Fractional Shares of Preferred
Stock for which a Right was exercisable immediately prior to such adjustment.
Each Right held of record prior to such adjustment of the number of Rights shall
become that number of Rights (calculated to the nearest 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 Rights Certificates have been issued, shall be at least
10 days later than the date of the public announcement. If Rights Certificates
have been issued, upon each adjustment of the number of Rights pursuant to this
SECTION 11(i), the Company shall, as promptly as practicable, cause to be
distributed to holders of record of Rights Certificates on such record date
Rights 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 Rights Certificates held by
such holders prior to the date of adjustment, and upon surrender thereof, if
required by the Company, new Rights Certificates evidencing all the Rights to
which such holders shall be entitled after such adjustment. Rights Certificates
so to be distributed shall be issued, executed and countersigned in the manner
provided for herein (and may bear, at the option of the Company, the adjusted
Purchase Price) and shall be registered in the names of the holders of record of
Rights 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 Fractional Shares of Preferred Stock issuable upon the exercise of
the Rights, the Rights

                                       19
<Page>

Certificates theretofore and thereafter issued may continue to express the
Purchase Price per Fractional Share and the number of Fractional Shares that
were expressed in the initial Rights Certificates issued hereunder.

          (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below the then par value, if any, or the stated capital of
the number of Fractional Shares of Preferred Stock or of the number of shares of
Common Stock or other securities issuable upon exercise of a Right, the Company
shall take any corporate action that may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable such number of Fractional Shares of Preferred Stock or such number
of shares of Common Stock or other securities 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 issuance to the holder of any Right exercised after such record date
the number of Fractional Shares of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of Fractional Shares of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise on the basis of
the Purchase Price in effect prior to such adjustment; PROVIDED, HOWEVER, that
the Company shall deliver to such holder a due bill or other appropriate
instrument evidencing such holder's right to receive such additional shares
(fractional or otherwise) or securities 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 in their good faith judgment the Board of Directors of the
Company shall determine to be advisable in order that any (i) consolidation or
subdivision of the Preferred Stock, (ii) issuance wholly for cash of any shares
of Preferred Stock at less than the current market price, (iii) issuance wholly
for cash of shares of Preferred Stock or securities that by their terms are
convertible into or exchangeable for shares of Preferred Stock, (iv) stock
dividends or (v) issuance of rights, options or warrants referred to in this
SECTION 11 hereafter made by the Company to holders of its Preferred Stock shall
not be taxable to such stockholders.

          (n) The Company covenants and agrees that it shall not, at any time
that there is an Acquiring Person, (i) consolidate with any other Person, (ii)
merge with or into any other Person, or (iii) sell, lease or transfer (or permit
one or more Subsidiaries to sell, lease or transfer), in one transaction or a
series of related transactions, assets or earning power aggregating more than
50% of the assets or earning power of the Company and its Subsidiaries (taken as
a whole) to any other Person or Persons, if (x) at the time of or immediately
after such consolidation, merger, sale, lease or transfer there are any rights,
warrants or other instruments or securities of the Company or any other Person
outstanding or agreements, arrangements or understandings in effect that 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, lease or transfer, the stockholders or other
equity owners 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

                                       20
<Page>

Associates, or (z) the identity, form or nature of organization of the Principal
Party (including, without limitation, the selection of the Person that will be
the Principal Party as a result of the Company's entering into one or more
consolidations, mergers, sales, leases, transfers or transactions with more than
one party) would preclude or limit the exercise of Rights or otherwise diminish
substantially or eliminate the benefits intended to be afforded by the Rights.

          (o) The Company covenants and agrees that, after the Distribution
Date, it will not, except as permitted by SECTION 23, SECTION 24 or SECTION 27
hereof, take (or permit any Subsidiary to take) any action if the purpose of
such action is to, or 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.

          (p) Notwithstanding SECTION 3(c) hereof or any other provision of this
Agreement to the contrary, in the event that the Company shall at any time after
the Record Date and prior to the Distribution Date (i) declare a dividend on the
outstanding shares of Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding shares of Common Stock, (iii) combine the outstanding
shares of Common Stock into a smaller number of shares or (iv) otherwise
reclassify the outstanding shares of Common Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), the number of Rights
associated with each share of Common Stock then outstanding, or issued or
delivered thereafter with Rights, 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 "ADJUSTMENT 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. In lieu of such adjustment in the number of Rights associated with
one share of Common Stock, the Company may elect to adjust the number of
Fractional Shares of Preferred Stock purchasable upon the exercise of one Right
and the Purchase Price. If the Company makes such election, the number of Rights
associated with one share of Common Stock shall remain unchanged, and the number
of Fractional Shares of Preferred Stock purchasable upon exercise of one Right
and the Purchase Price shall be proportionately adjusted so that (i) the number
of Fractional Shares of Preferred Stock purchasable upon exercise of a Right
following such adjustment shall equal the product of the number of Fractional
Shares of Preferred Stock purchasable upon exercise of a Right immediately prior
to such adjustment multiplied by the Adjustment Fraction and (ii) the Purchase
Price following such adjustment shall equal the product of the Purchase Price
immediately prior to such adjustment multiplied by the Adjustment Fraction.

          Section 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF
SHARES. Whenever an adjustment is made as provided in SECTION 11 or SECTION 13
hereof, the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Common Stock, a copy of such certificate and (c) mail a
brief summary thereof to each registered holder of a Rights Certificate (or, if
prior to the

                                       21
<Page>

Distribution Date, to each registered holder of a certificate representing
shares of Common Stock) in accordance with SECTION 26 hereof. The Rights Agent
shall be fully protected in relying on any such certificate and on any
adjustment therein contained.

          Section 13. CONSOLIDATION, MERGER OR SALE OR TRANSFER OF ASSETS OR
EARNING POWER.

          (a) In the event that, from and after the time an Acquiring Person has
become such, directly or indirectly, (x) the Company shall consolidate with, or
merge with and into, any other Person, and the Company shall not be the
continuing or surviving corporation of such consolidation or merger, (y) any
Person shall consolidate with, or merge with or into, the Company, and the
Company shall be the continuing or surviving corporation of such consolidation
or merger, and, in connection with such consolidation or merger, all or part of
the outstanding shares of Common Stock shall be changed into or exchanged for
stock or other securities of the Company or any other Person or cash or any
other property, or (z) the Company shall sell, lease or otherwise transfer (or
one or more of its Subsidiaries shall sell, lease or otherwise transfer), in one
transaction or a series of related transactions, assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any wholly owned Subsidiary of the Company or any combination thereof in one
or more transactions each of which complies (and all of which together comply)
with SECTION 11(o) hereof), then, and in each such case (except as may be
contemplated by SECTION 13(d) hereof), proper provision shall be made so that:
(i) the Purchase Price shall be adjusted to be the Purchase Price immediately
prior to the first occurrence of a Triggering Event multiplied by the number of
Fractional Shares of Preferred Stock for which a Right was exercisable
immediately prior to such first occurrence; (ii) on and after the Distribution
Date, each holder of a Right, except as provided in SECTION 7(e) hereof, shall
thereafter have the right to receive, upon the exercise thereof at the Purchase
Price in accordance with the terms of this Agreement, in lieu of shares of
Preferred Stock or Common Stock of the Company, such number of validly
authorized and issued, fully paid, nonassessable and freely tradeable shares of
Common Stock of the Principal Party (as such term is hereinafter defined), not
subject to any liens, encumbrances, rights of first refusal or other adverse
claims, as shall be equal to the result obtained by dividing the Purchase Price
by 50% of the Current Market Price per share of the Common Stock of such
Principal Party on the date of consummation of such Flip-Over Event; 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 this Agreement to reflect any events occurring after the date of
such first occurrence of a Triggering Event or after the date of such Flip-Over
Event, as applicable; (iii) such Principal Party shall thereafter be liable for,
and shall assume, by virtue of such Flip-Over Event, all the obligations and
duties of the Company pursuant to this Agreement; (iv) the term "COMPANY" shall
thereafter be deemed to refer to such Principal Party, it being specifically
intended that the provisions of SECTION 11 hereof shall apply only to such
Principal Party following the first occurrence of a Flip-Over Event; (v) such
Principal Party shall take such steps (including, but not limited to, the
reservation of a sufficient number of shares of its Common Stock) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions hereof shall thereafter be applicable, as nearly as reasonably
may be, in relation to its shares of

                                       22
<Page>

Common Stock thereafter deliverable upon the exercise of the Rights; and (vi)
the provisions of SECTION 11(a)(ii) hereof shall be of no effect following the
occurrence of any Flip-Over Event.

          (b) "PRINCIPAL PARTY" shall mean

          (i) in the case of any transaction described in clause (x) or (y) of
     the first sentence of SECTION 13(a), (A) the Person that is the issuer of
     any securities into which shares of Common Stock of the Company are
     converted in such merger or consolidation, or, if there is more than one
     such issuer, the issuer the Common Stock of which has the greatest
     aggregate market value, or (B) if no securities are so issued, (x) the
     Person that survives such consolidation or is the other party to the merger
     and survives such merger, or, if there is more than one such Person, the
     Person the Common Stock of which has the greatest aggregate market value 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); and

          (ii) in the case of any transaction described in clause (z) of the
     first sentence of SECTION 13(a), the Person that is the party receiving the
     greatest portion of the assets or earning power transferred pursuant to
     such transaction or transactions, or, if each Person that is a party to
     such transaction or transactions receives the same portion of the assets or
     earning power so transferred, or if the Person receiving the greatest
     portion of the assets or earning power cannot be determined, the Person the
     Common Stock of which has the greatest aggregate market value;

PROVIDED, HOWEVER, that in any such case, if the Common Stock of such Person is
not at such time and has not been continuously over the preceding twelve-month
period registered under Section 12 of the Exchange Act, and if (1) such Person
is a direct or indirect Subsidiary of another Person the Common Stock of which
is and has been so registered, "PRINCIPAL PARTY" shall refer to such other
Person; (2) such Person is a Subsidiary, directly or indirectly, of more than
one Person, the Common Stocks of all of which are and have been so registered,
"PRINCIPAL PARTY" shall refer to whichever of such Persons is the issuer of the
Common Stock having the greatest aggregate market value; and (3) 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 (1) and (2) above shall apply to each of the chains of ownership having
an interest in such joint venture as if such party were a "Subsidiary" of both
or all of such joint venturers and the Principal Parties in each such chain
shall bear the obligations set forth in this SECTION 13 in the same ratio as
their direct or indirect interests in such Person bear to the total of such
interests.

          (c) The Company shall not consummate any Flip-Over Event unless each
Principal Party (or Person that may become a Principal Party as a result of such
Flip-Over Event) shall have a sufficient number of authorized shares of its
Common Stock that have not been issued or reserved for issuance to permit the
exercise in full of the Rights in accordance with this SECTION 13 and unless
prior thereto the Company and each such Principal Party shall have executed and
delivered to the Rights Agent a supplemental agreement providing for the terms
set forth in paragraphs (a) and (b) of this SECTION 13 and further providing
that, as soon as practicable after the date of such Flip-Over Event, the
Principal Party at its own expense will

                                       23
<Page>

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

          (ii) use its best efforts to qualify or register the Rights and the
     securities purchasable upon exercise of the Rights under the "blue sky"
     laws of such jurisdictions as may be necessary or appropriate;

          (iii) use its best efforts, if the Common Stock of the Principal Party
     is or shall become listed on a national securities exchange, to list (or
     continue the listing of) the Rights and the securities purchasable upon
     exercise of the Rights on such securities exchange and, if the Common Stock
     of the Principal Party shall not be listed on a national securities
     exchange, to cause the Rights and the securities purchasable upon exercise
     of the Rights to be reported by NASDAQ or such other transaction reporting
     system then in use; and

          (iv) deliver to holders of the Rights historical financial statements
     for the Principal Party and each of its Affiliates that comply in all
     respects with the requirements for registration on Form 10 under the
     Exchange Act.

The provisions of this SECTION 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. In the event that a Flip-Over Event
shall occur at any time after the occurrence of a Flip-In Event, the Rights that
have not theretofore been exercised shall thereafter become exercisable in the
manner described in SECTION 13(a).

          (d) Notwithstanding anything in this Agreement to the contrary,
SECTION 13 shall not be applicable to a transaction described in subparagraphs
(x) and (y) of SECTION 13(a) if (i) such transaction is consummated with a
Person or Persons who acquired shares of Common Stock pursuant to a Permitted
Offer (or a wholly owned subsidiary of any such Person or Persons), (ii) the
price per share of Common Stock offered in such transaction is not less than the
price per share of Common Stock paid to all holders of Common Stock whose shares
were purchased pursuant to such Permitted Offer, and (iii) the form of
consideration being offered to the remaining holders of shares of Common Stock
pursuant to such transaction is the same as the form of consideration paid
pursuant to such Permitted Offer. Upon consummation of any such transaction
contemplated by this SECTION 13(d), all Rights hereunder shall expire.

          Section 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

          (a) The Company shall not be required to issue fractions of Rights,
except prior to the Distribution Date as provided in SECTION 11(p) hereof, or to
distribute Rights Certificates or scrip evidencing fractional Rights. In lieu of
such fractional Rights, there shall be paid to the registered holders of the
Rights Certificates with regard to which such fractional Rights would otherwise
be issuable, an amount in cash equal to the same fraction of the Closing Price
of one

                                       24
<Page>

Right for the Trading Day immediately prior to the date on which such fractional
Rights would have been otherwise issuable.

          (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than, except as provided in SECTION 7(c) hereof,
fractions that are integral multiples of a Fractional Share of Preferred Stock)
upon exercise of the Rights or to distribute certificates or scrip evidencing
fractional shares of Preferred Stock (other than, except as provided in SECTION
7(c) hereof, fractions that are integral multiples of a Fractional Share of
Preferred Stock). Interests in fractions of shares of Preferred Stock in
integral multiples of a Fractional Share of Preferred Stock may, at the election
of the Company in its sole discretion, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it, provided that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the shares of Preferred Stock
represented by such depositary receipts. In lieu of fractional shares of
Preferred Stock that are not integral multiples of a Fractional Share of
Preferred Stock, the Company may pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of one one-hundredth of the Closing Price of
a share of Preferred Stock for the Trading Day immediately prior to the date of
such exercise.

          (c) Following the occurrence of a Triggering Event, the Company shall
not be required to issue fractions of shares of Common Stock upon exercise of
the Rights or to distribute certificates or scrip evidencing fractional shares
of Common Stock. In lieu of fractional shares of Common Stock, the Company may
pay to the registered holders of Rights Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the
Closing Price of one share of Common Stock for the Trading Day immediately prior
to the date of such exercise.

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

          Section 15. RIGHTS OF ACTION. All rights of action in respect of this
Agreement, other than rights of action vested in the Rights Agent pursuant to
SECTION 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock) and, where applicable, the Company; and any registered holder of
any Rights 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
Rights Certificate (or, prior to the Distribution Date, of the Common Stock),
may, in his own behalf and for his own benefit, enforce, and may institute and
maintain any suit, action or proceeding against the Company to enforce, or
otherwise act in respect of, his right to exercise the Rights evidenced by such
Rights Certificate in the manner provided in such Rights 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
shall be entitled to specific performance of the obligations hereunder and
injunctive relief against actual or threatened violations of the obligations
hereunder of any Person subject to this Agreement. After a Triggering Event,
holders of Rights

                                       25
<Page>

shall be entitled to recover the reasonable costs and expenses, including
attorneys' fees, incurred by them in any action to enforce the provisions of
this Agreement.

          Section 16. AGREEMENT OF RIGHTS HOLDERS. Every holder of a Right by
accepting the same consents and agrees with the Company and the Rights Agent and
with every other holder of a Right that:

          (a) prior to the Distribution Date, the Rights will not be evidenced
by Rights Certificates and will be transferable only in connection with the
transfer of Common Stock;

          (b) after the Distribution Date, the Rights Certificates will be
transferable only on the registry books of the Rights Agent if surrendered at
the principal office or offices of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper instrument of transfer and
with the form of assignment set forth on the reverse side thereof and the
certificate contained therein duly completed and fully executed;

          (c) subject to SECTION 6(a) and SECTION 7(f) hereof, the Company and
the Rights Agent may deem and treat the Person in whose name a Rights
Certificate (or, prior to the Distribution Date, the associated Common Stock
certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or writing on the
Rights Certificates or the associated Common Stock certificate made by anyone
other than the Company or the Rights Agent) for all purposes whatsoever, and
neither the Company nor the Rights Agent shall be affected by any notice to the
contrary; and

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

          Section 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of Fractional
Shares of Preferred Stock or any other securities of the Company that may at any
time be issuable upon the exercise of the Rights represented thereby, nor shall
anything contained herein or in any Rights Certificate be construed to confer
upon the holder of any Rights Certificate, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in SECTION 25 hereof),
or to receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights 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
disbursements and other reasonable 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 in the premises.

          (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 Rights
Certificate or certificate for Common Stock or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement or other
paper or document believed by it, after proper inquiry or examination, to be
genuine and to be signed, executed and, where necessary, guaranteed, verified or
acknowledged, by the proper Person or Persons.

          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 corporate trust or stock transfer business of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto; PROVIDED, HOWEVER, 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 Rights
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of a predecessor Rights Agent and
deliver such Rights Certificates so countersigned; and in case at that time any
of the Rights Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Rights Certificates either in the name of the
predecessor or in the name of the successor Rights Agent; and in all such cases
such Rights Certificates shall have the full force provided in the Rights
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 Rights Certificates shall have been countersigned
but not delivered, the Rights Agent may adopt the countersignature under its
prior name and deliver Rights Certificates so countersigned; and in case at that
time any of the Rights Certificates shall not have been countersigned, the
Rights Agent may countersign such Rights Certificates either in its prior name
or in its changed name; and in all such cases such Rights Certificates shall
have the full force provided in the Rights Certificates and in this Agreement.

                                       27

          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 Rights 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
(including, without limitation, the identity of any Acquiring Person and the
determination of "Current Market Price") be proved or established by the Company
prior to taking or suffering any action hereunder, such fact or matter (unless
other evidence in respect thereof be herein specifically prescribed) may be
deemed to be conclusively proved and established by a certificate signed by the
Chairman of the Board, the Chief Executive Officer, the President, any Vice
President, the Treasurer, any Assistant Treasurer, the Secretary or any
Assistant 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 only for its own gross
negligence, bad faith or willful misconduct. In no event shall the Rights Agent
be liable for special, indirect or consequential loss or damage of any kind
whatsoever (including but not limited to lost profits), even if the Rights Agent
has been advised of the likelihood of such loss or damage and regardless of the
form of action.

          (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 Rights
Certificates or be required to verify the same (except as to its
countersignature on such Rights Certificates), 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 Rights 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 Rights Certificate; nor shall it
be responsible for any adjustment required under the provisions of SECTION 11 or
SECTION 13 hereof or responsible for the manner, method or amount of any such
adjustment or the ascertaining of the existence of facts that would require any
such adjustment (except with respect to the exercise of Rights evidenced by
Rights Certificates after receipt of actual knowledge of any such adjustment);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Preferred Stock
or Common Stock or other securities to be issued pursuant to this Agreement or
any Rights Certificate or as to whether any shares of Preferred Stock or Common
Stock or other securities will, when so issued, be validly authorized and
issued, fully paid and nonassessable.

                                       28
<Page>

          (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 the
Chairman of the Board, the Chief Executive Officer, the President, any Vice
President, the Secretary, any Assistant Secretary, the Treasurer or any
Assistant Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer.

          (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, omission, default, neglect or misconduct of any such
attorneys or agents or for any loss to the Company resulting from any such act,
omission, default, neglect or misconduct; PROVIDED, HOWEVER, that reasonable
care was exercised in the selection and continued employment thereof.

          (j) No provision of this Agreement shall require the Rights Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of its rights if
there shall be reasonable grounds for believing that repayment of such funds or
adequate indemnification against such risk or liability is not reasonably
assured to it.

          (k) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed or indicates an affirmative response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise or transfer without first consulting with the Company.

          Section 21. CHANGE OF RIGHTS AGENT. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon 30 days' notice in writing mailed to the Company, and to each transfer
agent of the Common Stock and the Preferred Stock, by registered or certified
mail, and to the registered holders, if any, of the Rights Certificates by
first-class mail. The Company may remove the Rights Agent or any successor
Rights Agent (with or without cause) 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 and the Preferred Stock, by registered or
certified mail, and to the registered holders of the

                                       29
<Page>

Rights Certificates, if any, by first-class mail. If the Rights Agent shall
resign or be removed or shall otherwise become incapable of acting, the Company
shall appoint a successor to the Rights Agent. Notwithstanding the foregoing
provisions of this SECTION 21, in no event shall the resignation or removal of a
Rights Agent be effective until a successor Rights Agent shall have been
appointed and have accepted such appointment. If the Company shall fail to make
such appointment within a period of 30 days after giving notice of such removal
or after it has been notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the registered holder of a
Rights Certificate (who shall, with such notice, submit his Rights Certificate
for inspection by the Company), then the Rights Agent or the registered holder
of any Rights 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 or trust
company organized and doing business under the laws of the United States, in
good standing, 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 $100,000,000 or (b) an affiliate of a
corporation or trust company 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 and the
Preferred Stock, and mail a notice thereof in writing to the registered holders
of the Rights 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 RIGHTS CERTIFICATES. Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Rights Certificates evidencing Rights in
such form as may be approved by its Board of Directors to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares or
other securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of shares of Common Stock following the Distribution
Date and prior to the Expiration Date, the Company (a) shall, with respect to
shares of Common Stock so issued or sold pursuant to the exercise of stock
options or under any employee plan or arrangement granted or awarded on or prior
to the Distribution Date, or upon the exercise, conversion or exchange of
securities issued by the Company on or prior to the Distribution Date, and (b)
may, in any other case, if deemed necessary or appropriate by the Board of
Directors of the Company, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale; PROVIDED, HOWEVER,
that (i) no such Rights Certificate shall be issued if, and to the extent that,
the Company shall be advised by counsel that such issuance would create a
significant risk of material adverse tax consequences to the Company or the
Person to whom such Rights Certificate would be issued, and (ii) no such Rights
Certificate shall be issued if, and to the

                                       30
<Page>

extent that, appropriate adjustment shall otherwise have been made in lieu of
the issuance thereof.

          Section 23. REDEMPTION AND TERMINATION.

          (a) The Board of Directors of the Company may, at its option, at any
time prior to the earlier of (i) the close of business on the tenth day
following the first date of public announcement of the occurrence of a Flip-In
Event and (ii) the Expiration Date, cause the Company to redeem all but not less
than all the then outstanding Rights at a redemption price of $0.01 per Right,
as such amount may be appropriately adjusted, if necessary, to reflect any stock
split, stock dividend or similar transaction (such redemption price being
hereinafter referred to as the "REDEMPTION PRICE"); PROVIDED, HOWEVER, that the
Rights may not be redeemed following any merger to which the Company is a party
that (i) occurs when there is an Acquiring Person and (ii) was not approved
prior to such merger by the Board of Directors of the Company and by the
stockholders of the Company at a stockholders' meeting. Notwithstanding anything
contained in this Agreement to the contrary, the Rights shall not be exercisable
after the first occurrence of a Flip-In Event until such time as the Company's
right of redemption hereunder has expired. The Company may, at its option, pay
the Redemption Price in cash, shares of Common Stock (based on the Current
Market Price of the Common Stock at the time of redemption) or any other form of
consideration deemed appropriate by the Board of Directors.

          (b) Immediately upon the effectiveness of the action of the Board of
Directors of the Company ordering the redemption of the Rights (the
effectiveness of which action may be conditioned on the occurrence of one or
more events or on the existence of one or more facts or may be effective at some
future time), evidence of which shall be filed with the Rights Agent and without
any further action and without any notice, the right to exercise the Rights will
terminate and the only right thereafter of the holders of Rights shall be to
receive the Redemption Price for each Right so held. Promptly after the
effectiveness of the action of the Board of Directors ordering the redemption of
the Rights, the Company shall give notice of such redemption to the Rights Agent
and the registered holders of the then outstanding Rights by mailing such notice
to all such holders at each holder's last address as it appears upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the Company for the Common Stock. Any notice that 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 and from time to time after the occurrence of a Flip-In Event, exchange all
or part of the then outstanding and exercisable Rights (which shall not include
Rights that have become void pursuant to the provisions of SECTION 7(e) hereof)
for shares of Common Stock or Common Stock Equivalents or any combination
thereof, at an exchange ratio of one share of Common Stock, or such number of
Common Stock Equivalents or units representing fractions thereof as would be
deemed to have the same value as one share of Common Stock, per Right,
appropriately adjusted, if necessary, to reflect any stock split, stock dividend
or similar transaction (such exchange ratio being hereinafter referred to as the
"EXCHANGE RATIO").

                                       31
<Page>

Notwithstanding the foregoing, the Board of Directors may not effect such
exchange at any time after (i) any Person (other than an Exempt Person),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the shares of Common Stock then outstanding
or (ii) the occurrence of a Flip-Over Event.

          (b) Immediately upon the effectiveness of the action of the Board of
Directors of the Company ordering the exchange of any Rights pursuant to and in
accordance with subsection (a) of this SECTION 24 (the effectiveness of which
action may be conditioned on the occurrence of one or more events or on the
existence of one or more facts or may be effective at some future time) 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 and/or Common Stock
Equivalents equal to the number of such Rights held by such holder multiplied by
the Exchange Ratio. The Company shall promptly give public notice of any such
exchange; PROVIDED, HOWEVER, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange. The Company promptly
shall mail a notice of any such exchange to all of the registered holders of
such Rights at their last addresses as they appear upon the registry books of
the Rights Agent. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of exchange will state the method by which the exchange of the shares of Common
Stock and/or Common Stock Equivalents for Rights will be effected and, in the
event of any partial exchange, the number of Rights that will be exchanged. Any
partial exchange shall be effected as nearly pro rata as possible based on the
number of Rights (other than Rights that have become void pursuant to the
provisions of SECTION 7(e) hereof) held by each holder of Rights.

          (c) In the event that the number of shares of Common Stock that are
authorized by the Company's certificate of incorporation but not outstanding or
reserved for issuance for purposes other than upon exercise of the Rights is not
sufficient to permit an exchange of Rights as contemplated in accordance with
this SECTION 24, the Company may, at its option, take all such action as may be
necessary to authorize additional shares of Common Stock for issuance upon
exchange of the Rights.

          (d) The Company shall not be required to issue fractions of shares of
Common Stock or to distribute certificates or scrip evidencing fractional shares
of Common Stock upon exchange of the Rights. In lieu of such fractional shares
of Common Stock, the Company shall pay to the registered holders of Rights 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 value of a whole
share of Common Stock. For purposes of this SECTION 24, the value of a whole
share of Common Stock shall be the Closing Price per share of Common Stock for
the Trading Day immediately prior to the date of exchange pursuant to this
SECTION 24, and the value of any Common Stock Equivalent shall be deemed to have
the same value as the Common Stock on such date.

          Section 25. NOTICE OF CERTAIN EVENTS.

          (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make

                                       32
<Page>

any other distribution to the holders of Preferred Stock (other than a regular
quarterly cash dividend out of earnings or retained earnings of the Company), or
(ii) to offer to the holders of Preferred Stock rights or warrants to subscribe
for or to purchase any additional shares of Preferred Stock or shares of stock
of any class or any other securities, rights or options, or (iii) to effect any
reclassification of its Preferred Stock (other than a reclassification involving
only the subdivision of outstanding shares of Preferred Stock), or (iv) to
effect any consolidation or merger into or with any other Person (other than a
wholly owned Subsidiary of the Company in a transaction that complies with
SECTION 11(o) hereof), or to effect any sale, lease or other transfer of all or
substantially all the Company's assets to any other Person or Persons (other
than a wholly owned Subsidiary of the Company in a transaction that complies
with SECTION 11(o) hereof), or (v) to effect the liquidation, dissolution or
winding up of the Company, then, in each such case, the Company shall give to
each holder of record of a Rights Certificate, to the extent feasible and in
accordance with SECTION 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, distribution of
rights or warrants, or the date on which such reclassification, consolidation,
merger, sale, lease, transfer, liquidation, dissolution or winding up is to take
place and the date of participation therein by the holders of the shares of
Preferred Stock, if any such date is to be fixed, and such notice shall be so
given in the case of any action covered by clause (i) or (ii) above at least 20
days prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action, at
least 20 days prior to the date of the taking of such proposed action or the
date of participation therein by the holders of the shares of Preferred Stock,
whichever shall be the earlier. The failure to give notice required by this
SECTION 25 or any defect therein shall not affect the legality or validity of
the action taken by the Company or the vote upon any such action.

          (b) In case any Flip-In Event or Flip-Over Event shall occur, then (i)
the Company shall as soon as practicable thereafter give to each registered
holder of a Rights Certificate (or if occurring prior to the Distribution Date,
the registered holders of Common Stock), in accordance with SECTION 26 hereof, a
notice of the occurrence of such event, which shall specify the event and the
consequences of the event to holders of Rights under SECTION 11(a)(ii) or
SECTION 13(a) hereof, and (ii) all references in the preceding paragraph to
Preferred Stock shall be deemed thereafter to refer to Common Stock and/or, if
appropriate, other securities.

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

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Rights Certificate (or, if
prior to the Distribution Date, to the holder of certificates representing
shares of Common Stock) shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Company.

          Section 27. SUPPLEMENTS AND AMENDMENTS. Except as provided in the last
sentence of this SECTION 27, at any time when the Rights are then redeemable,
the Company may in its sole and absolute discretion and the Rights Agent shall,
if the Company so directs, supplement or amend any provision of this Agreement
in any respect without the approval of any holders of Rights or holders of
Common Stock. At any time when the Rights are not redeemable, except as provided
in the last sentence of this SECTION 27, the Company may and the Rights Agent
shall, if the Company so directs, supplement or amend this Agreement without the
approval of any holders of Rights in order (i) to cure any ambiguity, (ii) to
correct or supplement any provision contained herein that may be defective or
inconsistent with any other provisions herein, (iii) to shorten or lengthen any
time period hereunder or (iv) to change or supplement the provisions hereunder
in any manner that the Company may deem necessary or desirable; provided that no
such amendment or supplement shall materially adversely affect the interests of
the holders of Rights (other than an Acquiring Person or an Affiliate or
Associate of an Acquiring Person); and further provided that this Agreement may
not be supplemented or amended pursuant to this sentence to lengthen (A) a time
period relating to when the Rights may be redeemed or (B) any other time period
unless the lengthening of such other time period is for the purpose of
protecting, enhancing or clarifying the rights of, and/or the benefits to, the
holders of Rights (other than any Acquiring Person and its Affiliates and
Associates). Upon the delivery of a certificate from an appropriate officer of
the Company which states that the proposed supplement or amendment is in
compliance with the terms of this SECTION 27, the Rights Agent shall execute
such supplement or amendment; PROVIDED, HOWEVER, that the Rights Agent may, but
shall not be obligated to, enter into any such supplement or amendment that
affects the Rights Agent's own rights, duties or immunities under this
Agreement. Notwithstanding anything contained in this Agreement to the contrary,
no supplement or amendment shall be made that decreases the Redemption Price.

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

          Section 29. DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS, ETC.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular

                                       34
<Page>

percentage of such outstanding shares of Common Stock of which any Person is the
Beneficial Owner, shall, subject to the last sentence of the definition of
Beneficial Owner in SECTION 1, be made in accordance with the last sentence of
Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act
as in effect on the date of this Agreement. The Board of Directors of the
Company (or, as set forth herein, certain specified members thereof) shall have
the exclusive power and authority to administer this Agreement and to exercise
all rights and powers specifically granted to the Board of Directors of the
Company or to the Company, or as may be necessary or advisable in the
administration of this Agreement, including, without limitation, the right and
power to (i) interpret the provisions of this Agreement and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including, without limitation, a determination to redeem or not
redeem the Rights or to amend this Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) that are done or made by the Board
of Directors of the Company in good faith, shall (x) be final, conclusive and
binding on the Company, the Rights Agent, the holders of the Rights, as such,
and all other parties, and (y) not subject the Board of Directors to any
liability to the holders of the Rights.

          Section 30. BENEFITS OF THIS AGREEMENT. Nothing in this Agreement
shall be construed to give to any Person other than the Company, the Rights
Agent and the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of the Common Stock) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock).

          Section 31. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
PROVIDED, HOWEVER, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, then, unless there has occurred any merger referred to
in the proviso to the first sentence of SECTION 23(a), the right of redemption
set forth in SECTION 23 hereof shall be reinstated and shall not expire until
the close of business on the tenth day following the date of such determination
by the Board of Directors of the Company or, if earlier, immediately prior to
any such merger. Without limiting the foregoing, if any provision requiring that
a determination be made by less than the entire Board of Directors of the
Company is held by a court of competent jurisdiction or other authority to be
invalid, void or unenforceable, such determination shall then be made by the
entire Board of Directors of the Company.

          Section 32. GOVERNING LAW. This Agreement, each Right and each Rights
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts made
and to be performed entirely within such State.

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

         PURSUANT TO SECTION 151 OF THE DELAWARE GENERAL CORPORATION LAW

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

      Hospira, Inc. (the "CORPORATION"), a corporation organized and existing
under the Delaware General Corporation Law, in accordance with the provisions
of Section 103 thereof, DOES HEREBY CERTIFY:

     That pursuant to the authority vested in the Corporation's board of
directors in accordance with the provisions of the Restated Certificate of
Incorporation of the Corporation, the Corporation's board of directors on
[________ __], 2004, adopted the following resolution creating a series of _____
million (_____) shares of Preferred Stock designated as "Series A Junior
Participating Preferred Stock":

          RESOLVED, that, pursuant to the authority vested in the Board in
     accordance with the provisions of the Restated Certificate of
     Incorporation, a series of Preferred Stock, par value $0.01 per share, of
     the Corporation be and hereby is created, and that the designation and
     number of shares thereof and the voting and other powers, preferences and
     relative, participating, optional or other rights of the shares of such
     series and the qualifications, limitations and restrictions thereof are as
     follows:

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

          1. DESIGNATION AND AMOUNT. There shall be a series of Preferred Stock
that shall be designated as "Series A Junior Participating Preferred Stock," and
the number of shares constituting such series shall be _____ million (_____).
Such number of shares may be increased or decreased by resolution of the Board
of Directors; PROVIDED, HOWEVER, that no decrease shall reduce the number of
shares of Series A Junior Participating Preferred Stock to less than the number
of shares then issued and outstanding plus the number of shares issuable upon
exercise of outstanding rights, options or warrants or upon conversion of
outstanding securities issued by the Corporation.

          2. DIVIDENDS AND DISTRIBUTIONS.

          (A) Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series A Junior Participating

                                       A-1
<Page>

Preferred Stock with respect to dividends, the holders of shares of Series A
Junior Participating Preferred Stock, in preference to the holders of shares of
any class or series of stock of the Corporation ranking junior to the Series A
Junior Participating 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 1st day of March, June,
September and December in each year (each such date being referred to herein as
a "QUARTERLY DIVIDEND PAYMENT DATE"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series A Junior Participating Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $1.00 or (b) the Adjustment
Number (as defined below) times the aggregate per share amount of all cash
dividends, and the Adjustment Number times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions other than a
dividend payable in shares of Common Stock or a subdivision of the outstanding
shares of Common Stock (by reclassification or otherwise), declared on the
Common Stock, par value $0.01 per share, of the Corporation (the "COMMON STOCK")
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first issuance
of any share or fraction of a share of Series A Junior Participating Preferred
Stock. The "ADJUSTMENT NUMBER" shall initially be 100. In the event the
Corporation shall at any time (i) declare any dividend on Common Stock payable
in shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

          (B) The Corporation shall declare a dividend or distribution on the
Series A Junior Participating Preferred Stock as provided in paragraph (A) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); PROVIDED that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series A Junior Participating Preferred Stock shall nevertheless be payable on
such subsequent Quarterly Dividend Payment Date.

          (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Junior Participating Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares of Series
A Junior Participating Preferred Stock, unless the date of issue of such shares
is prior to the record date for the first Quarterly Dividend Payment Date, in
which case dividends on such shares shall begin to accrue from the date of issue
of such shares, or unless the date of issue is a Quarterly Dividend Payment Date
or is a date after the record date for the determination of holders of shares of
Series A Junior Participating Preferred Stock entitled to receive a quarterly
dividend and before such Quarterly Dividend Payment Date, in either of which
events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series A Junior Participating
Preferred Stock in an

                                       A-2
<Page>

amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series A Junior
Participating Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be no more than 30 days
prior to the date fixed for the payment thereof.

          3. VOTING RIGHTS.  The holders of shares of Series A Junior
Participating Preferred Stock shall have the following voting rights:

          (A) Each share of Series A Junior Participating Preferred Stock shall
entitle the holder thereof to a number of votes equal to the Adjustment Number
on all matters submitted to a vote of the stockholders of the Corporation.

          (B) Except as otherwise provided herein, in the Certificate of
Incorporation or by law, the holders of shares of Series A Junior Participating
Preferred Stock, the holders of shares of any other class or series entitled to
vote with the Common Stock and the holders of shares of Common Stock shall vote
together as one class on all matters submitted to a vote of stockholders of the
Corporation.

          (C) (i) If at any time dividends on any Series A Junior Participating
Preferred Stock shall be in arrears in an amount equal to six quarterly
dividends thereon, the occurrence of such contingency shall mark the beginning
of a period (herein called a "DEFAULT PERIOD") that shall extend until such time
when all accrued and unpaid dividends for all previous quarterly dividend
periods and for the current quarterly dividend period on all shares of Series A
Junior Participating Preferred Stock then outstanding shall have been declared
and paid or set apart for payment. During each default period, (1) the number of
Directors shall be increased by two, effective as of the time of election of
such Directors as herein provided, and (2) the holders of Preferred Stock
(including holders of the Series A Junior Participating Preferred Stock) upon
which these or like voting rights have been conferred and are exercisable (the
"VOTING PREFERRED STOCK") with dividends in arrears in an amount equal to six
quarterly dividends thereon, voting as a class, irrespective of series, shall
have the right to elect such two Directors.

                  (ii) During any default period, such voting right of the
holders of Series A Junior Participating Preferred Stock may be exercised
initially at a special meeting called pursuant to subparagraph (iii) of this
Section 3(C) or at any annual meeting of stockholders, and thereafter at annual
meetings of stockholders, provided that such voting right shall not be exercised
unless the holders of at least one-third in number of the shares of Voting
Preferred Stock outstanding shall be present in person or by proxy. The absence
of a quorum of the holders of Common Stock shall not affect the exercise by the
holders of Voting Preferred Stock of such voting right.

                  (iii) Unless the holders of Voting Preferred Stock shall,
during an existing default period, have previously exercised their right to
elect Directors, the Board of Directors may order, or any stockholder or
stockholders owning in the aggregate not less than ten percent of the total
number of shares of Voting Preferred Stock outstanding, irrespective of series,
may request, the calling of a special meeting of the holders of Voting Preferred
Stock, which meeting

                                       A-3
<Page>

shall thereupon be called by the Chairman of the Board, the Chief Executive
Officer, the President, a Vice President or the Secretary of the Corporation.
Notice of such meeting and of any annual meeting at which holders of Voting
Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii) shall
be given to each holder of record of Voting Preferred Stock by mailing a copy of
such notice to him at his last address as the same appears on the books of the
Corporation. Such meeting shall be called for a time not earlier than 20 days
and not later than 60 days after such order or request or, in default of the
calling of such meeting within 60 days after such order or request, such meeting
may be called on similar notice by any stockholder or stockholders owning in the
aggregate not less than ten percent of the total number of shares of Voting
Preferred Stock outstanding. Notwithstanding the provisions of this paragraph
(C)(iii), no such special meeting shall be called during the period within 60
days immediately preceding the date fixed for the next annual meeting of the
stockholders.

                  (iv) In any default period, after the holders of Voting
Preferred Stock shall have exercised their right to elect Directors voting as a
class, (x) the Directors so elected by the holders of Voting Preferred Stock
shall continue in office until their successors shall have been elected by such
holders or until the expiration of the default period, and (y) any vacancy in
the Board of Directors may be filled by vote of a majority of the remaining
Directors theretofore elected by the holders of the class or classes of stock
which elected the Director whose office shall have become vacant. References in
this paragraph (C) to Directors elected by the holders of a particular class or
classes of stock shall include Directors elected by such Directors to fill
vacancies as provided in clause (y) of the foregoing sentence.

                  (v) Immediately upon the expiration of a default period, (x)
the right of the holders of Voting Preferred Stock as a class to elect Directors
shall cease, (y) the term of any Directors elected by the holders of Voting
Preferred Stock as a class shall terminate and (z) the number of Directors shall
be such number as may be provided for in the Certificate of Incorporation or
By-Laws irrespective of any increase made pursuant to the provisions of
paragraph (C) of this Section 3 (such number being subject, however, to change
thereafter in any manner provided by law or in the Certificate of Incorporation
or By-Laws). Any vacancies in the Board of Directors effected by the provisions
of clauses (y) and (z) in the preceding sentence may be filled by a majority of
the remaining Directors.

          (D) Except as set forth herein, holders of Series A Junior
Participating 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.

          4. CERTAIN RESTRICTIONS.

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

                                       A-4
<Page>

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

                  (ii) declare or pay dividends on or make any other
     distributions on any shares of stock ranking on a parity (either as to
     dividends or upon liquidation, dissolution or winding up) with the Series A
     Junior Participating Preferred Stock, except dividends paid ratably on the
     Series A Junior Participating 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; or

                  (iii) redeem or purchase or otherwise acquire for
     consideration any shares of Series A Junior Participating Preferred Stock,
     or any shares of stock ranking on a parity with the Series A Junior
     Participating 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 Series A Junior Participating Preferred Stock, or to all
     such holders and the holders of any such shares ranking on a parity
     therewith, 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 Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

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

          6. LIQUIDATION, DISSOLUTION OR WINDING UP. (A) Upon any liquidation
(voluntary or otherwise), dissolution or winding up of the Corporation, no
distribution shall be made to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to
the Series A Junior Participating Preferred Stock unless, prior thereto, the
holders of shares of Series A Junior Participating Preferred Stock shall have
received $1.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "SERIES A LIQUIDATION PREFERENCE"). Following the payment
of the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series A Junior
Participating Preferred Stock unless, prior thereto, the holders of shares of
Common Stock shall have received an amount per share (the "COMMON
ADJUSTMENT") equal to the quotient obtained by dividing (i) the Series A
Liquidation Preference by (ii) the Adjustment Number. Following the payment
of the


                                       A-5
<Page>

full amount of the Series A Liquidation Preference and the Common Adjustment
in respect of all outstanding shares of Series A Junior Participating
Preferred Stock and Common Stock, respectively, holders of Series A Junior
Participating Preferred Stock and holders of shares of Common Stock shall,
subject to the prior rights of all other series of Preferred Stock, if any,
ranking prior thereto, receive their ratable and proportionate share of the
remaining assets to be distributed in the ratio of the Adjustment Number to 1
with respect to such Series A Junior Participating Preferred Stock and Common
Stock, on a per share basis, respectively.

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

          (C) Neither the merger or consolidation of the Corporation into or
with another corporation nor the merger or consolidation of any other
corporation into or with the Corporation shall be deemed to be a liquidation,
dissolution or winding up of the Corporation within the meaning of this Section
6, but the sale, lease or conveyance of all or substantially all the
Corporation's assets shall be deemed to be a liquidation, dissolution or winding
up of the Corporation within the meaning of this Section 6.

          7. CONSOLIDATION, MERGER, ETC. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share equal to the Adjustment
Number times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged.

          8. REDEMPTION. (A) The Corporation, at its option, may redeem shares
of the Series A Junior Participating Preferred Stock in whole at any time and in
part from time to time, at a redemption price equal to the Adjustment Number
times the current per share market price (as such term is hereinafter defined)
of the Common Stock on the date of the mailing of the notice of redemption,
together with unpaid accumulated dividends to the date of such redemption. The
"CURRENT PER SHARE MARKET PRICE" on any date shall be deemed to be the average
of the closing price per share of such Common Stock for the ten 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 Common Stock is determined during a period following the
announcement of (A) a dividend or distribution on the Common Stock other than a
regular quarterly cash dividend or (B) any subdivision, combination or
reclassification of such Common Stock and the ex-dividend date for such dividend
or distribution, or the record date for such subdivision, combination or
reclassification, shall not have occurred prior to the commencement of such ten
Trading Day period, then, and in each such case, the current per share market
price shall be properly adjusted to take into account ex-dividend trading. The

                                       A-6
<Page>

closing price for each day shall be the last sales 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
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange, or, if the Common Stock is not listed or
admitted to trading on the New York Stock Exchange, on the principal national
securities exchange on which the Common Stock is listed or admitted to trading,
or, if the Common Stock is not listed or admitted to trading on any national
securities exchange but sales price information is reported for such security,
as reported by the National Association of Securities Dealers, Inc. Automated
Quotations System ("NASDAQ") or such other self-regulatory organization or
registered securities information processor (as such terms are used under the
Securities Exchange Act of 1934, as amended) that then reports information
concerning the Common Stock, or, if sales price information is not so reported,
the average of the high bid and low asked prices in the over-the-counter market
on such day, as reported by NASDAQ or such other entity, or, if on any such date
the Common Stock is not quoted by any such entity, the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Common Stock selected by the Board of Directors of the Corporation. If on
any such date no such market maker is making a market in the Common Stock, the
fair value of the Common Stock on such date as determined in good faith by the
Board of Directors of the Corporation shall be used. The term "TRADING DAY"
shall mean a day on which the principal national securities exchange on which
the Common Stock is listed or admitted to trading is open for the transaction of
business, or, if the Common Stock is not listed or admitted to trading on any
national securities exchange but is quoted by NASDAQ, a day on which NASDAQ
reports trades, or, if the Common Stock is not so quoted, a Monday, Tuesday,
Wednesday, Thursday or Friday on which banking institutions in the State of New
York are not authorized or obligated by law or executive order to close.

          (B) In the event that fewer than all the outstanding shares of the
Series A Junior Participating Preferred Stock are to be redeemed, the number of
shares to be redeemed shall be determined by the Board of Directors and the
shares to be redeemed shall be determined by lot or pro rata as may be
determined by the Board of Directors or by any other method that may be
determined by the Board of Directors in its sole discretion to be equitable.

          (C) Notice of any such redemption shall be given by mailing to the
holders of the shares of Series A Junior Participating Preferred Stock to be
redeemed a notice of such redemption, first class postage prepaid, not later
than the fifteenth day and not earlier than the sixtieth day before the date
fixed for redemption, at their last address as the same shall appear upon the
books of the Corporation. Each such notice shall state: (i) the redemption date;
(ii) the number of shares to be redeemed and, if fewer than all the shares held
by such holder are to be redeemed, the number of such shares to be redeemed from
such holder; (iii) the redemption price; (iv) the place or places where
certificates for such shares are to be surrendered for payment of the redemption
price; and (v) that dividends on the shares to be redeemed will cease to accrue
on the close of business on such redemption date. Any notice that is mailed in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the stockholder received such notice, and failure duly to
give such notice by mail, or any defect in such notice, to any holder of
Series A Junior Participating Preferred Stock shall not affect the validity of
the proceedings for the redemption of any other shares of Series A Junior
Participating Preferred Stock that are to be redeemed. On or after the date
fixed for redemption as stated in such notice,

                                       A-7
<Page>

each holder of the shares called for redemption shall surrender the certificate
evidencing such shares to the Corporation at the place designated in such notice
and shall thereupon be entitled to receive payment of the redemption price. If
fewer than all the shares represented by any such surrendered certificate are
redeemed, a new certificate shall be issued representing the unredeemed shares.

          (D) The shares of Series A Junior Participating Preferred Stock shall
not be subject to the operation of any purchase, retirement or sinking fund.

          9. RANKING. The Series A Junior Participating Preferred Stock shall
rank junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise, and shall rank senior to the Common Stock
as to such matters.

          10. AMENDMENT. At any time that any shares of Series A Junior
Participating Preferred Stock are outstanding, the Certificate of Incorporation
of the Corporation shall not be amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A Junior
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of two-thirds or more of the outstanding shares
of Series A Junior Participating Preferred Stock, voting separately as a class.

          11. FRACTIONAL SHARES. Series A Junior Participating 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 Junior Participating Preferred Stock.

     IN WITNESS WHEREOF, the undersigned has executed this Certificate and does
affirm the foregoing as true this [____] day of [_________] 2004.

NOT EXERCISABLE AFTER [_________ __], 20[__] OR EARLIER IF REDEEMED OR EXCHANGED
BY THE COMPANY. THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE
COMPANY, AT $0.01 PER RIGHT ON THE TERMS SET FORTH IN THE RIGHTS AGREEMENT.
UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS
BENEFICIALLY OWNED BY OR TRANSFERRED TO ANY PERSON WHO IS, WAS OR BECOMES AN
ACQUIRING PERSON OR AN AFFILIATE OR ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED
IN THE RIGHTS AGREEMENT) AND CERTAIN TRANSFEREES THEREOF WILL BECOME NULL AND

                                 Hospira, Inc.

     This certifies that _____________________, or registered assigns, is the
registered owner of the number of Rights set forth above, each of which
entitles the owner thereof, subject to the terms, provisions and conditions of
the Rights Agreement, dated as of ________ __, 2004, as it may from time to time
be supplemented or amended (the "RIGHTS AGREEMENT"), between Hospira, Inc., a
Delaware corporation (the "COMPANY"), and EquiServe Trust Company, N.A., a
national banking association (the "RIGHTS AGENT"), to purchase from the Company
at any time prior to 5:00 p.m. (New York City time) on _________ __, 20__ at the
principal office or offices of the Rights Agent designated for such purpose, or
its successors as Rights Agent, one one-hundredth of a fully paid, nonassessable
share (a "FRACTIONAL SHARE") of Series A Junior Participating Preferred Stock
(the "PREFERRED STOCK") of the Company, at a purchase price of $______ per one
one-hundredth of a share (the "PURCHASE PRICE"), upon presentation and surrender
of this Rights Certificate with the Form of Election to Purchase and related
Certificate set forth on the reverse hereof duly executed. The Purchase Price
may be paid in cash or by certified check, cashier's or official bank check or
bank draft payable to the order of the Company or the Rights Agent. The number
of Rights evidenced by this Rights Certificate (and the number of shares which
may be purchased upon exercise thereof) set forth above, and the Purchase Price
per Fractional Share set forth above, are the number and Purchase Price as of
________ __, 2004, based on the Preferred Stock as constituted at such date. The
Company reserves the right to require prior to the occurrence of a Triggering
Event (as such term is defined in the Rights Agreement) that a number of Rights
be exercised so that only whole shares of Preferred Stock will be issued.

     From and after the first occurrence of a Triggering Event (as such term is
defined in the Rights Agreement), if the Rights evidenced by this Rights
Certificate are beneficially owned by or transferred to (i) an Acquiring Person
or an Associate or Affiliate of an Acquiring Person (as such terms are defined
in the Rights Agreement), (ii) a transferee of any such Acquiring Person,

                                       B-1
<Page>

Associate or Affiliate, or (iii) under certain circumstances specified in the
Rights Agreement, a transferee of a person who, concurrently with or after such
transfer, became an Acquiring Person or an Affiliate or Associate of an
Acquiring Person, such Rights shall, with certain exceptions, become null and
void in the circumstances set forth in the Rights Agreement, and no holder
hereof shall have any rights whatsoever with respect to such Rights from and
after the occurrence of such Triggering Event.

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

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

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

     Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Certificate (i) may be redeemed by the Company at its option at a
redemption price of $0.01 per Right, payable, at the election of the Company, in
cash or shares of Common Stock or such other consideration as the Board of
Directors may determine, at any time prior to the earlier of the close of
business on (a) the tenth day following the first public announcement of the
occurrence of a Flip-In Event (as such time period may be extended or shortened
pursuant to the Rights Agreement) and (b) the Expiration Date (as such term is
defined in the Rights Agreement) or (ii) may be exchanged in whole or in part
for shares of the Company's Common Stock, par value $0.01 per share, and/or
other equity securities of the Company deemed to have the same value as shares
of Common Stock, at any time prior to a person's becoming the beneficial owner
of 50% or more of the shares of Common Stock outstanding or the occurrence of a
Flip-Over Event.

     No fractional shares of Preferred Stock are required to be issued upon the
exercise of any Right or Rights evidenced hereby (other than, except as set
forth above, fractions that are integral multiples of a Fractional Share of
Preferred Stock, which may, at the election of the Company,

                                       B-2
<Page>

be evidenced by depositary receipts), but in lieu thereof a cash payment may be
made, as provided in the Rights Agreement.

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

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

     WITNESS the signature of the proper officers of the Company and its
corporate seal.
