WARRANT AGREEMENT1

     THIS AGREEMENT dated as of [            ] between AMERIGROUP CORPORATION, a Delaware
corporation (the “Company”), and [            ], a [bank] [trust company] duly incorporated and
existing under the laws of [            ], as Warrant Agent (the “Warrant Agent”),

     Bracketed language here and throughout this Agreement should be inserted as follows:

     1. If Warrants are immediately detachable from the Offered Securities; and

     2. If Warrants are detachable from the Offered Securities only after the Detachable Date.

W I T N E S S E T H :

     [WHEREAS, the Company has entered into an Indenture dated as of [Date] (the “Senior
Indenture”) between the Company and [           ], as Trustee (the “Senior Indenture Trustee”), and an
Indenture dated as of [Date] (the “Subordinated Indenture”) between the Company and [           ], as Trustee
(the “Subordinated Indenture Trustee”) (together the “Trustees” or “Trustee” and “Indentures” or
“Indenture”), providing for the issuance from time to time of its unsecured debt securities to be
issued in one or more series as provided in the Indenture; and]

     WHEREAS, the Company proposes to sell [title of such securities being offered] (the “Offered
Securities”) with one or more warrants (the “Warrants”) representing the right to purchase [title
of such securities purchasable through exercise of Warrants] (the “Warrant Securities”), the
Warrants to be evidenced by warrant certificates issued pursuant to this Agreement (the “Warrant
Certificates”); and

     WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company in connection
with the issuance, transfer, exchange, exercise and replacement of the Warrant Certificates, and in
this Agreement wishes to set forth, among other things, the form and provisions of the Warrant

ARTICLE 1

ISSUANCE OF WARRANTS AND EXECUTION AND DELIVERY OF WARRANT

CERTIFICATES

     SECTION 1.01. Issuance of Warrants. 

     The Warrants shall be evidenced by one or more Warrant Certificates. Each Warrant evidenced
thereby shall represent the right, subject to the provisions contained herein and therein, to
purchase [___shares of the Warrant Securities] [___aggregate principal amount of Warrant
Securities] and shall be initially issued in connection with the issuance of the Offered Securities
[1: and shall be separately transferable immediately thereafter] [2: but shall not be separately
transferable until on and after      , (the “Detachable Date”)]. The Warrants shall be initially
issued [in units] with the Offered Securities, and each Warrant [included in such a unit] shall
evidence the right, subject to the provisions contained herein and in the Warrant Certificates, to
purchase [___shares of the Warrant Securities] [___aggregate principal amount of Warrant
Securities] [included in such a unit].

     SECTION 1.02. Execution and Delivery of Warrant Certificates. 

     Each Warrant, whenever issued, shall be evidenced by a Warrant Certificate in registered form
substantially in the form set forth in Exhibit A hereto, shall be dated and may have such letters,
numbers or other marks of identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as the officers of the Company executing the same may approve
(execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the
provisions of this Agreement, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock exchange on which the
Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf
of the Company by its chairman or vice chairman of the Board of Directors, the chief financial
officer, the president, any vice president, any assistant vice president, the treasurer or any
assistant treasurer of the Company, which may but need not be attested by its secretary or one of
its assistant secretaries. Such signatures may be manual or facsimile signatures of such authorized
officers and may be imprinted or otherwise reproduced on the Warrant Certificates.

     No Warrant Certificate shall be valid for any purpose, and no Warrant evidenced thereby shall
be exercisable, until such Warrant Certificate has been countersigned by the Warrant Agent by
manual signature. Such signature by the Warrant Agent upon any Warrant Certificate executed by the
Company shall be conclusive evidence, and the only evidence, that the Warrant Certificate so
countersigned has been duly issued hereunder.

     In case any officer of the Company who shall have signed any of the Warrant Certificates
either manually or by facsimile signature shall cease to be such officer before the Warrant
Certificates so signed shall have been countersigned and delivered by the Warrant Agent as provided
herein, such Warrant Certificates may be countersigned and

2

 

delivered notwithstanding that the person who signed such Warrant Certificates ceased to be
such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by
such persons as, at the actual date of the execution of such Warrant Certificate, shall be the
proper officers of the Company, although at the date of the execution of this Agreement any such
person was not such officer.

     The term “Holder,” when used with respect to any Warrant Certificate shall mean any person in
whose name at the time such Warrant Certificate shall be registered upon the books to be maintained
by the Warrant Agent for that purpose [2: or, prior to the Detachable Date, any person in whose
name at the time the Offered Security to which such Warrant Certificate is attached is registered
upon the register of the Offered Securities. Prior to the Detachable Date, the Company will, or
will cause the registrar of the Offered Securities to, make available at all times to the Warrant
Agent such information as to holders of the Offered Securities with Warrants as may be necessary to
keep the Warrant Agent’s records up to date.]

     SECTION 1.03. Issuance of Warrant Certificates. 

     Warrant Certificates evidencing the right to purchase [___shares of the Warrant Securities]
[an aggregate principal amount not exceeding ___aggregate principal amount of Warrant
Securities] (except as provided in Sections 2.03, 3.02 and 4.01) may be executed by the Company and
delivered to the Warrant Agent upon the execution of this Warrant Agreement or from time to time
thereafter. The Warrant Agent shall, upon receipt of Warrant Certificates duly executed on behalf
of the Company, countersign Warrant Certificates evidencing [ ] Warrants representing the
right to purchase up to [___shares of the Warrant Securities] [___aggregate principal amount
of Warrant Securities] and shall deliver such Warrant Certificates to or upon the order of the
Company. Subsequent to such original issuance of the Warrant Certificates, the Warrant Agent shall
countersign a Warrant Certificate only if the Warrant Certificate is issued in exchange or
substitution for one or more previously countersigned Warrant Certificates or in connection with
their transfer as hereinafter provided or as provided in the antepenultimate paragraph of Section
2.03.

     Pending the preparation of definitive Warrant Certificates evidencing Warrants, the Company
may execute and the Warrant Agent shall countersign and deliver temporary Warrant Certificates
evidencing such Warrants (printed, lithographed, typewritten or otherwise produced, in each case in
form satisfactory to the Warrant Agent). Such temporary Warrant Certificates shall be issuable
substantially in the form of the definitive Warrant Certificates but with such omissions,
insertions and variations as may be appropriate for temporary Warrant Certificates, all as may be
determined by the Company with the concurrence of the Warrant Agent. Such temporary Warrant
Certificates may contain such reference to any provisions of this Warrant Agreement as may be
appropriate. Every such temporary Warrant Certificate shall be executed by the Company and shall be
countersigned by the Warrant Agent upon the same conditions and in substantially the same manner,
and with like effect, as the definitive Warrant Certificates. Without unreasonable delay, the
Company shall execute and shall furnish definitive Warrant Certificates and thereupon such
temporary Warrant Certificates may

3

 

be surrendered in exchange therefor without charge pursuant to and subject to the provisions
of Section 4.01, and the Warrant Agent shall countersign and deliver in exchange for such temporary
Warrant Certificates definitive Warrant Certificates of authorized denominations evidencing a like
aggregate number of Warrants evidenced by such temporary Warrant Certificates. Until so exchanged,
such temporary Warrant Certificates shall be entitled to the same benefits under this Warrant
Agreement as definitive Warrant Certificates.

ARTICLE 2

WARRANT PRICE, DURATION AND EXERCISE OF WARRANTS

     SECTION 2.01. Warrant Price. 

     On [            ], the exercise price of each Warrant will be [            ]. During the period from [           
], through and including [            ], the exercise price of each Warrant will be [           ] [plus
[accrued amortization of the original issue discount] [accrued interest] from ___.] [In each
case, the original issue discount will be amortized at a [ ]% annual rate, computed on an annual
basis using the “interest” method and using a 360-day year consisting of twelve 30-day months].
Such exercise price of Warrant Securities is referred to in this Agreement as the “Warrant Price.”
[The original issue discount for each principal amount of
Warrant Securities is
        ].

     SECTION 2.02. Duration of Warrants.

     Subject to Section 4.03(b), each Warrant may be exercised [in whole but not in part] [in whole
or in part] [at any time, as specified herein, on or after [the date thereof] [___] and at or
before [time, location] on [            ] (each day during such period may hereinafter be referred to as
an “Exercise Date”)] [on [list of specific dates] (each, an “Exercise Date”)], or such later date
as the Company may designate by notice to the Warrant Agent and the Holders of Warrant Certificates
[in registered form and to the beneficial owners of the Global Warrant Certificate] (the
“Expiration Date”). Each Warrant not exercised at or before [time, location] on the Expiration Date
shall become void, and all rights of the Holder [and any beneficial owners] of the Warrant
Certificate evidencing such Warrant under this Agreement shall cease.

     SECTION 2.03. Exercise of Warrants.

     [With respect to Warrants evidenced by Warrant Certificates in registered form, during]
[During] the period specified in Section 2.02, any whole number of Warrants may be exercised by
providing certain information as set forth on the reverse side of the Warrant Certificates
evidencing such Warrants and by paying in full [in lawful money of the United States of America]
[in applicable currency] [in cash] [by certified check or official bank check or by bank wire
transfer, in each case,] [by bank wire transfer] [in immediately available funds,] the Warrant
Price for each Warrant exercised [(plus accrued interest, if any, on the Warrant Securities to be
issued upon exercise of such Warrant from and including the Interest Payment Date (as defined in
the Indenture), if any, in respect of such Warrant Securities immediately preceding the Exercise
Date to

4

 

and including the Exercise Date (unless the Exercise Date is after the Regular Record Date (as
defined in the Indenture), if any, for such Interest Payment Date, but on or before the immediately
succeeding Interest Payment Date for such Warrant Securities, in which event no such accrued
interest shall be payable))] to the Warrant Agent at its corporate trust office at [address] [or at      ], provided that such exercise is subject to receipt within five business days of such
[payment] [wire transfer] by the Warrant Agent of the Warrant Certificate evidencing each Warrant
exercised with the form of election to purchase Warrant Securities set forth on the reverse side of
the Warrant Certificate properly completed and duly executed. [Cashless Exercise Option].

     The date on which payment in full of the Warrant Price (plus any such accrued interest) is
received by the Warrant Agent shall, subject to receipt of the Warrant Certificate as aforesaid, be
deemed to be the date on which the Warrant is exercised. The Warrant Agent shall deposit all funds
received by it in payment for the exercise of Warrants in an account of the Company maintained with
it (or in such other account as may be designated by the Company) and shall advise the Company, by
telephone or by facsimile transmission or other form of electronic communication available to both
parties, at the end of each day on which a payment for the exercise of Warrants is received of the
amount so deposited to its account. The Warrant Agent shall promptly confirm such advice to the
Company in writing.

     If a day on which Warrants may be exercised in the city in which such Warrants are to be
exercised shall be a Saturday or Sunday or a day on which banking institutions in such city are
authorized or required to be closed, then, notwithstanding any other provision of this Agreement or
the Warrant Certificate evidencing such Warrants, but subject to the limitation that no Warrant may
be exercised after the Expiration Date, the Warrants shall be exercisable on the next succeeding
day which in such city is not a Saturday or Sunday or a day on which banking institutions in such
city are authorized or required to be closed.

     The Warrant Agent shall, from time to time, as promptly as practicable, advise the Company
[and the Trustee] in writing of (i) the number of Warrants exercised, (ii) the instructions of each
Holder of the Warrant Certificates evidencing such Warrants with respect to delivery of the Warrant
Securities to be issued upon such exercise, (iii) delivery of any Warrant Certificates evidencing
the balance, if any, of the Warrants remaining after such exercise, and (iv) such other information
as the Company or the Trustee shall reasonably require.

     As soon as practicable after the exercise of any Warrant, but subject to receipt by the
Warrant Agent of the Warrant Certificate evidencing such Warrant as provided in this Section, the
Company shall issue[, pursuant to the Indenture, in authorized denominations to or upon the order
of the Holder of the Warrant Certificate evidencing each Warrant,] the Warrant Securities to which
such Holder is entitled, in fully registered form, registered in such name or names as may be
directed by such Holder. If fewer than all of the Warrants evidenced by such Warrant Certificate
are exercised, the Company shall execute, and an authorized officer of the Warrant Agent shall
manually countersign and

5

 

deliver, a new Warrant Certificate evidencing the number of such Warrants remaining
unexercised.

     The Company shall not be required to pay any stamp or other tax or other governmental charge
required to be paid in connection with any transfer involved in the issuance of the Warrant
Securities, and in the event that any such transfer is involved, the Company shall not be required
to issue or deliver any Warrant Security until such tax or other charge shall have been paid or it
has been established to the Company’s satisfaction that no such tax or other charge is due.

ARTICLE 3

OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANT

     SECTION 3.01. No Rights as Warrant Securityholder Conferred by Warrants or Warrant
Certificates. 

     No Warrant Certificate or Warrant evidenced thereby shall entitle the Holder or any beneficial
owner thereof to any of the rights of a holder or beneficial owner of Warrant Securities,
including, without limitation, [the right to receive the payment of principal of (premium, if any)
or interest, if any, on Warrant Securities or to enforce any of the covenants in the Indenture]
[the right to receive dividend payments on the Warrant Securities or any voting rights].

     SECTION 3.02. Lost, Mutilated, Stolen or Destroyed Warrant Certificates.

     Upon receipt by the Warrant Agent of evidence reasonably satisfactory to it and the Company of
the ownership of and the loss, mutilation, theft or destruction of any Warrant Certificate and of
such security or indemnity as may be required by the Company and the Warrant Agent to hold each of
them and any agent of them harmless and, in the case of mutilation of a Warrant Certificate, upon
surrender thereof to the Warrant Agent for cancellation, then, in the absence of notice to the
Company or the Warrant Agent that such Warrant Certificate has been acquired by a bona fide
purchaser, the Company shall execute, and an authorized officer of the Warrant Agent shall manually
countersign and deliver, in exchange for or in lieu of the lost, mutilated, stolen or destroyed

Warrant Certificate, a new Warrant Certificate of the same tenor and evidencing a like number of
Warrants. Upon the issuance of any new Warrant Certificate under this Section, the Company may
require the payment of a sum sufficient to cover any stamp or other tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including the fees and
expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate
executed and delivered pursuant to this Section in lieu of any lost, mutilated, stolen or destroyed
Warrant Certificate shall represent an additional contractual obligation of the Company, whether or
not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone,
and shall be entitled to the benefits of this Agreement equally and proportionately with any and
all other Warrant Certificates duly executed and delivered hereunder. The provisions of this
Section are exclusive and shall preclude (to the extent

6

 

lawful) all other rights and remedies with respect to the replacement of lost, mutilated,
stolen or destroyed Warrant Certificates.

     SECTION 3.03. Enforcement of Rights.

     Notwithstanding any of the provisions of this Agreement, any Holder of a Warrant Certificate,
without the consent of the Warrant Agent, the Trustee, the holder of any Offered Securities or the
Holder of any other Warrant Certificate, may, in its own behalf and for its own benefit, enforce,
and may institute and maintain any suit, action or proceeding against the Company suitable to
enforce, or otherwise in respect of, its right to exercise its Warrants in the manner provided in
its Warrant Certificate and in this Agreement.

     SECTION 3.04. Merger, Consolidation, Conveyance or Transfer.

     (a) If at any time there shall be a merger or consolidation of the Company or a conveyance or
transfer of its property and assets substantially as an entirety [as permitted under the
Indenture], then in any such event the successor or assuming corporation referred to therein shall
succeed to and be substituted for the Company, with the same effect[, subject to the Indenture,] as
if it had been named herein and in the Warrant Certificates as the Company; the Company shall
thereupon, except in the case of a transfer by way of lease, be relieved of any further obligation
hereunder and under the Warrants and the Warrant Certificates, and the Company as the predecessor
corporation, except in the case of a transfer by way of lease, may thereupon or at any time
thereafter be dissolved, wound up or liquidated. Such successor or assuming corporation may
thereupon cause to be signed, and may issue either in its own name or in the name of the Company,
Warrant Certificates evidencing any or all of the Warrants issuable hereunder which theretofore
shall not have been signed by the Company, and may execute and deliver Warrant Securities in its
own name [, pursuant to the Indenture], in fulfillment of its obligations to deliver Warrant
Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the
same legal rank and benefit under this Agreement as the Warrants theretofore or thereafter issued
in accordance with the terms of this Agreement as though all of such Warrants had been issued at
the date of the execution hereof. In any case of any such merger, consolidation, conveyance or
transfer, such changes in phraseology and form (but not in substance) may be made in the Warrant
Certificates representing the Warrants thereafter to be issued as may be appropriate.

     (b) The Warrant Agent may receive a written opinion of legal counsel (who shall be acceptable
to the Warrant Agent) as conclusive evidence that any such merger, consolidation, conveyance or
transfer complies with the provisions of this Section and the Indentures.

     [Add Anti-Dilution provisions as necessary.]

ARTICLE 4

EXCHANGE AND TRANSFER

     SECTION 4.01. Exchange and Transfer.

     (a) [1: Upon] [2: Prior to the Detachable Date, a Warrant Certificate may be exchanged or
transferred only together with the Offered Security to which such Warrant Certificate was initially
attached, and only for the purpose of effecting, or in conjunction with, an exchange or transfer of
such Offered Security. Prior to any Detachable Date, each transfer of the Offered Security, shall
operate also to transfer the related Warrant Certificates. On or after the Detachable Date, upon] surrender at the corporate trust office of the Warrant Agent at [address] [or        ], Warrant
Certificates evidencing Warrants may be exchanged for Warrant Certificates in other authorized
denominations evidencing such Warrants or the transfer thereof may be registered in whole or in
part; provided, however, that such other Warrant Certificates shall evidence the same aggregate
number of Warrants as the Warrant Certificates so surrendered.

     (b) The Warrant Agent shall keep, at its corporate trust office at [address] [and
at       ], books in which, subject to such reasonable regulations as it may prescribe, it shall
register Warrant Certificates and exchanges and transfers of outstanding Warrant Certificates upon
surrender of such Warrant Certificates to the Warrant Agent at its corporate trust office at
[address] [or        ] for exchange or registration of transfer, properly endorsed [or accompanied
by appropriate instruments of registration of transfer and written instructions for transfer, all
in form satisfactory to the Company and the Warrant Agent.]

     (c) No service charge shall be made for any exchange or registration of transfer of Warrant
Certificates, but the Company may require payment of a sum sufficient to cover any stamp or other
tax or other governmental charge that may be imposed in connection with any such exchange or
registration of transfer.

     (d) Whenever any Warrant Certificates, are so surrendered for exchange or registration of
transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the
person or persons entitled thereto a Warrant Certificate or Warrant Certificates, duly authorized
and executed by the Company, as so requested. The Warrant Agent shall not effect any exchange or
registration of transfer which will result in the issuance of a Warrant Certificate, evidencing a
fraction of a Warrant or a number of full Warrants and a fraction of a Warrant.

     (e) All Warrant Certificates, issued upon any exchange or registration of transfer of Warrant
Certificates shall be the valid obligations of the Company, evidencing the same obligations, and
entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for
such exchange or registration or transfer.

8

 

     SECTION 4.02. Treatment of Holders of Warrant Certificates.

     Each Holder of a Warrant Certificate, by accepting the same, consents and agrees with the
Company, the Warrant Agent and every subsequent Holder of such Warrant Certificate that until the
transfer of such Warrant Certificate is registered on the books of such Warrant Agent [2: or, prior
to the Detachable Date, until the transfer of the Offered Security to which such Warrant
Certificate is attached, is registered in the register of the Offered Securities], the Company and
the Warrant Agent may treat the registered Holder of such Warrant Certificate as the absolute owner
thereof for any purpose and as the person entitled to exercise the rights represented by the
Warrants evidenced thereby, any notice to the contrary notwithstanding.

     SECTION 4.03. Cancellation of Warrant Certificates.

     [(a)] Any Warrant Certificate surrendered for exchange or registration of transfer or exercise
of the Warrants evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant
Agent, and all Warrant Certificates surrendered or so delivered to the Warrant Agent shall be
promptly cancelled by the Warrant Agent and shall not be reissued and, except as expressly
permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor
or in lieu thereof. The Warrant Agent shall cause all cancelled Warrant Certificates to be
destroyed and shall deliver a certificate of such destruction to the Company.

     [(b) If the Company notifies the Trustee of its election to redeem [2: prior to the Detachable
Date] [, as a whole but not in part,] [2: the Offered Securities [or] [and]] the Warrant Securities
pursuant to the Indenture or the terms thereof, the Company may elect, and shall give notice to the
Warrant Agent of its election, to cancel the unexercised Warrants, the Warrant Certificates and the
rights evidenced thereby. Promptly after receipt of such notice by the Warrant Agent, the Company
shall, or, at the Company’s request, the Warrant Agent shall in the name of and at the expense of
the Company, give notice of such cancellation to the Holders of the Warrant Certificates, such
notice to be so given not less than 30 nor more than 60 days prior to the date fixed for the
redemption of [2: the Offered Securities [or] [and]] the Warrant Securities pursuant to the
Indenture or the terms thereof. The unexercised Warrants, the Warrant Certificates and the rights
evidenced thereby shall be cancelled and become void on the 15th day prior to such date fixed for
redemption.]

ARTICLE 5

CONCERNING THE WARRANT AGENT

     SECTION 5.01. Warrant Agent.

     The Company hereby appoints [        ] as Warrant Agent of the Company in respect of the
Warrants and the Warrant Certificates upon the terms and subject to the conditions herein and in
the Warrant Certificates set forth; and [       ] hereby accepts such appointment. The Warrant
Agent shall have the powers and authority granted to and conferred upon it in the Warrant
Certificates and herein and such further powers and

9

 

authority to act on behalf of the Company as the Company may hereafter grant to or confer upon
it. All of the terms and provisions with respect to such powers and authority contained in the
Warrant Certificates are subject to and governed by the terms and provisions hereof.

     SECTION 5.02. Conditions of Warrant Agent’s Obligations.

     The Warrant Agent accepts its obligations herein set forth upon the terms and conditions
hereof, including the following, to all of which the Company agrees and to all of which the rights
hereunder of the Holders from time to time of the Warrant Certificates shall be subject:

     (a) Compensation and Indemnification. The Company agrees promptly to pay the Warrant Agent the
compensation to be agreed upon with the Company for all services rendered by the Warrant Agent and
to reimburse the Warrant Agent for reasonable out-of-pocket expenses (including reasonable
attorneys’ fees) incurred by the Warrant Agent without negligence, bad faith or willful misconduct
or breach of this Agreement on its part in connection with the services rendered hereunder by the
Warrant Agent. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, bad faith or willful
misconduct on the part of the Warrant Agent, arising out of or in connection with its acting as
Warrant Agent hereunder, as well as the reasonable costs and expenses of defending against any
claim of such liability.

     (b) Agent for the Company. In acting under this Agreement and in connection with the Warrants
and the Warrant Certificates, the Warrant Agent is acting solely as agent of the Company and does
not assume any obligation or relationship of agency or trust for or with any of the Holders of
Warrant Certificates or beneficial owners of Warrants.

     (c) Counsel. The Warrant Agent may consult with counsel satisfactory to it in its reasonable
judgment, and the advice of such counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance
with the advice of such counsel.

     (d) Documents. The Warrant Agent shall be protected and shall incur no liability for or in
respect of any action taken or thing suffered by it in reliance upon any Warrant Certificate,
notice, direction, consent, certificate, affidavit, statement or other paper or document reasonably
believed by it to be genuine and to have been presented or signed by the proper parties.

     (e) Certain Transactions. The Warrant Agent, and its officers, directors and employees, may
become the owner of, or acquire any interest in, Warrants, with the same rights that it or they
would have if it were not the Warrant Agent hereunder, and, to the extent permitted by applicable
law, it or they may engage or be interested in any financial or other transaction with the Company
and may act on, or as depositary, trustee or agent for, any committee or body of holders of Warrant
Securities or other obligations of the

10

 

Company as freely as if it were not the Warrant Agent hereunder. [Nothing in this Warrant
Agreement shall be deemed to prevent the Warrant Agent from acting as Trustee under the Indenture.]

     (f) No Liability for Interest. The Warrant Agent shall have no liability for interest on any
monies at any time received by it pursuant to any of the provisions of this Agreement or of the
Warrant Certificates.

     (g) No Liability for Invalidity. The Warrant Agent shall not be under any responsibility with
respect to the validity or sufficiency of this Agreement or the execution and delivery hereof
(except the due authorization to execute this Agreement and the due execution and delivery hereof
by the Warrant Agent) or with respect to the validity or execution of any Warrant Certificates
(except its countersignature thereof).

     (h) No Liability for Recitals. The recitals contained herein shall be taken as the statements
of the Company and the Warrant Agent assumes no liability for the correctness of the same.

     (i) No Implied Obligations. The Warrant Agent shall be obligated to perform only such duties
as are herein and in the Warrant Certificates specifically set forth and no implied duties or
obligations shall be read into this Agreement or the Warrant Certificates against the Warrant
Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which may
tend to involve it in any expense or liability, the payment of which within a reasonable time is
not, in its reasonable opinion, assured to it. The Warrant Agent shall not be accountable or under
any duty or responsibility for the use by the Company of any of the Warrant Certificates
countersigned by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or
for the application by the Company of the proceeds of the Warrant Certificates. The Warrant Agent
shall have no duty or responsibility in case of any default by the Company in the performance of
its covenants or agreements contained herein or in the Warrant Certificates or in the case of the
receipt of any written demand from a Holder of a Warrant Certificate with respect to such default,
including, without limiting the generality of the foregoing, any duty or responsibility to initiate
or attempt to initiate any proceedings at law or otherwise or, except as provided in Section 6.02,
to make any demand upon the Company.

     SECTION 5.03. Resignation and Appointment of Successor.

     (a) The Company agrees, for the benefit of the Holders from time to time of the Warrant
Certificates, that there shall at all times be a Warrant Agent hereunder until all the Warrants
have been exercised or are no longer exercisable.

     (b) The Warrant Agent may at any time resign as such by giving written notice of its
resignation to the Company, specifying the desired date on which its resignation shall become
effective; provided, however, that such date shall be not less than 90 days after the date on which
such notice is given unless the Company agrees to accept shorter notice. Upon receiving such notice
of resignation, the Company shall promptly appoint a

11

 

successor Warrant Agent (which shall be a bank or trust company in good standing, authorized
under the laws of the jurisdiction of its organization to exercise corporate trust powers) by
written instrument in duplicate signed on behalf of the Company, one copy of which shall be
delivered to the resigning Warrant Agent and one copy to the successor Warrant Agent. The Company
may, at any time and for any reason, remove the Warrant Agent and appoint a successor Warrant Agent
(qualified as aforesaid) by written instrument in duplicate signed on behalf of the Company and
specifying such removal and the date when it is intended to become effective, one copy of which
shall be delivered to the Warrant Agent being removed and one copy to the successor Warrant Agent.
Any resignation or removal of the Warrant Agent and any appointment of a successor Warrant Agent
shall become effective upon acceptance of appointment by the successor Warrant Agent as provided in
this subsection (b). In the event a successor Warrant Agent has not been appointed and accepted its
duties within 90 days of the Warrant Agent’s notice of resignation, the Warrant Agent may apply to
any court of competent jurisdiction for the designation of a successor Warrant Agent. Upon its
resignation or removal, the Warrant Agent shall be entitled to the payment by the Company of the
compensation and to the reimbursement of all reasonable out-of-pocket expenses (including
reasonable attorneys’ fees) incurred by it hereunder as agreed to in Section 5.02(a).

     (c) The Company shall remove the Warrant Agent and appoint a successor Warrant Agent if the
Warrant Agent (i) shall become incapable of acting, (ii) shall be adjudged bankrupt or insolvent,
(iii) shall commence a voluntary case or other proceeding seeking liquidation, reorganization or
other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law
now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian
or other similar official of it or any substantial part of its property, (iv) shall consent to, or
shall have had entered against it a court order for, any such relief or to the appointment of or
taking possession by any such official in any involuntary case or other proceedings commenced
against it, (v) shall make a general assignment for the benefit of creditors or (vi) shall fail
generally to pay its debts as they become due. Upon the appointment as aforesaid of a successor
Warrant Agent and acceptance by it of such appointment, the predecessor Warrant Agent shall, if not
previously disqualified by operation of law, cease to be Warrant Agent hereunder.

     (d) Any successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to
its predecessor and the Company an instrument accepting such appointment hereunder, and thereupon
such successor Warrant Agent, without any further act, deed or conveyance, shall become vested with
all the authority, rights, powers, immunities, duties and obligations of such predecessor with like
effect as if originally named as Warrant Agent hereunder, and such predecessor shall thereupon
become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be
entitled to receive, all monies, securities and other property on deposit with or held by such
predecessor as Warrant Agent hereunder.

     (e) Any corporation into which the Warrant Agent hereunder may be merged or

12

 

converted or any corporation with which the Warrant Agent may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall
be a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or
substantially all the assets and business of the Warrant Agent, provided that it shall be qualified
as aforesaid, shall be the successor Warrant 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.

15

 

and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Purchase Contract Agent
and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the
Holders signing such instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this Agreement and
(subject to Section 7.1) conclusive in favor of the Purchase Contract Agent and the Company, if
made in the manner provided in this Section.

               (b) The fact and date of the execution by any Person of any such instrument or writing may be

Agent or the Company in reliance thereon, whether or not notation of such action is made upon such
Certificate.

Outstanding Units entitled to give, make or take any request, demand, authorization, direction,
notice, consent, waiver or other action provided or permitted by this Agreement to be given, made
or taken by Holders of Units. If any record date is set pursuant to this paragraph, the Holders of
the Outstanding Corporate Units and the Outstanding Treasury Units, as the case may be, on such
record date, and no other Holders, shall be entitled to take the relevant action with respect to
the Corporate Units or the Treasury Units, as the case may be, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite number of
Outstanding Units on such record date. Nothing contained in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any
Person be cancelled and be of no effect), and nothing contained in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite number of Outstanding
Units on the date such action is taken. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Purchase Contract Agent in
writing and to each Holder of Units in the manner set forth in Section 1.6.

16

 

                    With respect to any record date set pursuant to this Section, the Company may designate any
date as the “Expiration Date” and from time to time may change the Expiration Date to any earlier
or later day; provided that no such change shall be effective unless notice of the proposed new
Expiration Date is given to the Purchase Contract Agent in writing, and to each Holder of Units in
the manner set forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration
Date is not designated with respect to any record date set pursuant to this Section, the Company
shall be deemed to have initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as provided in this
paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day
after the applicable record date.

          Where this Agreement provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at its address as it appears in
the applicable Register, not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed to any particular
Holder shall affect the sufficiency of such notice with respect to other Holders. Where this
Agreement provides for notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the Purchase Contract
Agent, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by reason of any other cause it
shall be impracticable to give such notice by mail, then such notification as shall be made with
the approval of the Purchase Contract Agent shall constitute a sufficient notification for every

full force and effect in such jurisdiction and shall be liberally construed in order to carry out
the intentions of the parties hereto as nearly as may be possible and (ii) the invalidity or
unenforceability of any provision of this Agreement in any jurisdiction shall not in any way affect
the validity or enforceability of such provision in any other jurisdiction.

other provision of this Agreement, the Corporate Unit Certificates or the Treasury Unit
Certificates) payments by or owed from the Company contemplated by this Agreement shall not be made
on such date, but shall be made on the next succeeding Business Day with the same force and effect
as if made on such Payment Date, provided that no interest shall accrue or be payable by the
Company or any Holder for the period from and after any such Payment Date, except that, if such
next succeeding Business Day is in the next succeeding calendar year, such payment shall be made on
the immediately preceding Business Day with the same force and effect as if made on such Payment

     Unless this Certificate is presented by an authorized representative

The Units

Section 3.1 Amount; Form and Denominations.

          The aggregate number of Units evidenced by Certificates authenticated, executed on behalf of
the Holders and delivered hereunder is limited to                      (or up to                      if the
Underwriters’ over-allotment option pursuant to the Underwriting Agreement is exercised in full),
except for Certificates authenticated,

21

 

executed and delivered upon registration of transfer of, in
exchange for, or in lieu of, other Certificates pursuant to Sections 3.4, 3.5, 3.10, 3.13, 3.14,
5.9 or 5.10.

          The Certificates shall be issuable only in registered form and only in denominations of a
single Corporate Unit or Treasury Unit and any integral multiple thereof.

Section 3.2 Rights and Obligations Evidenced by the Certificates.

          Each Corporate Unit Certificate shall evidence the number of Corporate Units specified
therein, with each such Corporate Unit representing (1) the ownership by the Holder thereof of a
beneficial interest in one Debt Security or, if substituted therefor, the Pledged Treasury
Portfolio Interest, in either case, subject to the Pledge of such Debt Security or such Pledged
Treasury Portfolio Interest, as the case may be, by such Holder pursuant to the Pledge Agreement,
and (2) the rights and obligations of the Holder thereof and the Company under one Purchase
Contract. The Purchase Contract Agent as attorney-in-fact for, and on behalf of, the Holder of each
Corporate Unit shall pledge, pursuant to the Pledge Agreement, the Debt Security or, if substituted
therefor, the Treasury Portfolio Interest, forming a part of such Corporate Unit, to the Collateral
Agent and grant to the Collateral Agent a security interest in the right, title and interest of
such Holder in such Debt Security or such Treasury Portfolio Interest, as the case may be, for the
benefit of the Company, to secure the obligation of the Holder under each Purchase Contract to
purchase shares of Common Stock pursuant to the Purchase Contract.

          Upon the formation of Treasury Units pursuant to Section 3.13, each Treasury Unit Certificate
shall evidence the number of Treasury Units specified therein, with each such Treasury Unit
representing (1) the ownership by the Holder thereof of a 1/20 undivided beneficial interest in a
Treasury Security with a principal amount equal to $1,000, subject to the Pledge of such Treasury
Security by such Holder pursuant to the Pledge Agreement, and (2) the rights and obligations of the
Holder thereof and the Company under one Purchase Contract. The Purchase Contract Agent as
attorney-in-fact for, and on behalf of, the Holder of each Treasury Unit shall pledge, pursuant to
the Pledge Agreement, the Treasury Security or Treasury Securities forming a part of such Treasury
Unit, to the Collateral Agent and grant to the Collateral Agent a security interest in the right,
title and interest of such Holder in such Treasury Security or Treasury Securities for the benefit
of the Company, to secure the obligation of the Holder under each Purchase Contract to purchase
shares of Common Stock pursuant to this Agreement and the related Purchase Contract.

          Prior to the purchase of shares of Common Stock under each Purchase Contract, such Purchase
Contract shall not entitle the Holder of a Corporate Unit Certificate or a Treasury Unit
Certificate to any of the rights of a holder of shares of Common Stock, including, without
limitation, the right to vote or receive any dividends or other payments or to consent or to
receive notice as a shareholder in respect of the meetings of shareholders or for the election of
directors of the Company or for any other matter, or any other rights whatsoever as a shareholder
of the Company.

Section 3.3 Execution, Authentication, Delivery and Dating.

          Subject to the provisions of Sections 3.1, 3.13 and 3.14 hereof, upon the execution and
delivery of this Agreement, and at any time and from time to time thereafter, the Company may
deliver Certificates executed by the Company to the Purchase Contract Agent for authentication,
execution on behalf of the Holders and delivery, together with its Issuer Order for authentication
of such Certificates, and the
Purchase Contract Agent in accordance with such Issuer Order shall authenticate, execute on
behalf of the Holders and deliver such Certificates.

          The Certificates shall be executed on behalf of the Company by its Chairman of the Board,
President, one of its Vice Presidents, Corporate Secretary or Treasurer. The signature of any of
these officers on the Certificates may be manual or facsimile.

          Certificates bearing the manual or facsimile signatures of an individual who was at any time
the proper officer of the Company shall bind the Company, notwithstanding that such individual has
ceased to hold such office prior to the authentication and delivery of such Certificates or did not
hold such office at the date of such Certificates.

          No Purchase Contract evidenced by a Certificate shall be valid until such Certificate has been
executed on behalf of the Holder by the manual signature of an authorized officer of the Purchase
Contract Agent, as such Holder’s attorney-in-fact. Such signature by an authorized officer of the
Purchase Contract Agent shall be conclusive evidence that the Holder of such Certificate has
entered into the Purchase Contract or Purchase Contracts evidenced by such Certificate.

          Each Certificate shall be dated the date of its authentication.

          No Certificate shall be entitled to any benefit under this Agreement or be valid or obligatory
for any purpose unless there appears on such Certificate a certificate of authentication
substantially in the form provided for herein executed by an authorized officer of the Purchase
Contract Agent by manual signature, and such certificate upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly authenticated and delivered
hereunder.

Section 3.4 Temporary Certificates.

          Pending the preparation of definitive Certificates, the Company shall execute and deliver to
the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf
of the Holders, and deliver, in lieu of such definitive Certificates, temporary Certificates which
are in substantially the form set forth in Exhibit A or Exhibit B hereto, as the case may be, with
such letters, numbers or other marks of identification or designation and such legends or
endorsements printed, lithographed or engraved thereon as may be required by the rules of any
securities exchange on which the Corporate Units or Treasury Units are or may be listed, or as may,

23

 

consistently herewith, be determined by the officers of the Company executing such Certificates, as
evidenced by their execution of the Certificates.

          If temporary Certificates are issued, the Company will cause definitive Certificates to be
prepared without unreasonable delay. After the preparation of definitive Certificates, the
temporary Certificates shall be exchangeable for definitive Certificates
upon surrender of the temporary Certificates at the Corporate Trust Office, at the expense of
the Company and without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Certificates, the Company shall execute and deliver to the Purchase Contract Agent, and
the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver in
exchange therefor, one or more definitive Certificates of like tenor and denominations and
evidencing a like aggregate number of Corporate Units or Treasury Units, as the case may be, as the
temporary Certificate or Certificates so surrendered. Until so exchanged, the temporary
Certificates shall in all respects evidence the same benefits and the same obligations with respect
to the Corporate Units or Treasury Units, as the case may be, evidenced thereby as definitive
Certificates.

Section 3.5 Registration; Registration of Transfer and Exchange.

          The Purchase Contract Agent shall keep at the Corporate Trust Office a register (the
“Corporate Units Register”) in which, subject to such reasonable regulations as it may prescribe,
the Purchase Contract Agent shall provide for the registration of Corporate Unit Certificates and
of transfers of Corporate Unit Certificates (the Purchase Contract Agent, in such capacity, the
“Corporate Units Registrar”) and a register (the “Treasury Units Register”) in which, subject to
such reasonable regulations as it may prescribe, the Purchase Contract Agent shall provide for the
registration of the Treasury Unit Certificates and transfers of Treasury Unit Certificates (the
Purchase Contract Agent, in such capacity, the “Treasury Units Registrar”).

          Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office,
the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract
Agent shall authenticate, execute on behalf of the designated transferee or transferees, and
deliver, in the name of the designated transferee or transferees, one or more new Certificates of
any authorized denominations, like tenor, and evidencing a like aggregate number of Corporate Units
or Treasury Units, as the case may be.

          At the option of the Holder, Certificates may be exchanged for other Certificates, of any
authorized denominations and evidencing a like number of Corporate Units or Treasury Units, as the
case may be, upon surrender of the Certificates to be exchanged at the Corporate Trust Office.
Whenever any Certificates are so surrendered for exchange, the Company shall execute and deliver to
the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf
of the Holder, and deliver the Certificates which the Holder making the exchange is entitled to

receive.

          All Certificates issued upon any registration of transfer or exchange of a Certificate shall
evidence the ownership of the same aggregate number of Corporate

24

 

Units or Treasury Units, as the
case may be, and be entitled to the same benefits and subject to the same obligations, under this
Agreement as the Corporate Units or Treasury Units, as the case may be, evidenced by the
Certificate surrendered upon such registration of transfer or exchange.

          Every Certificate presented or surrendered for registration of transfer or for exchange shall
(if so required by the Purchase Contract Agent) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Purchase Contract Agent duly
executed, by the Holder thereof or its attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or exchange of a Certificate,
but the Company and the Purchase Contract Agent may require payment from the Holder of a sum
sufficient to cover any tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Certificates, other than any exchanges pursuant to Sections
3.4, 3.6 and 8.5 not involving any transfer.

          Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to
the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to
authenticate, execute on behalf of the Holder and deliver any Certificate in exchange for any other
Certificate presented or surrendered for registration of transfer or for exchange on or after the
Business Day immediately preceding the earlier of the Purchase Contract Settlement Date or the
Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable
conditions specified above in this Section and receipt of appropriate registration or transfer
instructions from such Holder, the Purchase Contract Agent shall:

               (1) if the Purchase Contract Settlement Date has occurred, deliver the shares
of Common Stock issuable in respect of the Purchase Contracts forming a part of
the Units evidenced by such other Certificate; or

               (2) if a Termination Event shall have occurred prior to the Purchase Contract
Settlement Date, transfer the Debt Securities, the Treasury Portfolio or the
Treasury Securities, as the case may be, evidenced thereby,

in each case subject to the applicable conditions and in accordance with the applicable provisions
of Article Five hereof.

Section 3.6 Book-Entry Interests.

          The Certificates, on original issuance, will be issued in the form of one or more fully
registered Global Certificates, to be delivered to the Depositary or its custodian by, or on behalf
of, the Company. Such Global Certificate shall initially be registered on the books and records of
the Company in the name of Cede & Co., the

25

 

nominee of the Depositary, and no Beneficial Owner will
receive a definitive Certificate representing such Beneficial Owner’s interest in such Global
Certificate, except as provided in Section 3.9. The Purchase Contract Agent shall enter into an
agreement with the Depositary if so requested by the Company. Unless and until definitive, fully
registered Certificates have been issued to Beneficial Owners pursuant to Section 3.9:

               (1) the provisions of this Section 3.6 shall be in full force and effect;

               (2) the Company shall be entitled to deal with the Depositary for all
purposes of this Agreement (including making Purchase Contract Adjustment Payments
and receiving approvals, votes or consents hereunder) as the Holder of the Units
and the sole holder of the Global Certificates and shall have no obligation to the
Beneficial Owners;

               (3) to the extent that the provisions of this Section 3.6 conflict with any
other provisions of this Agreement, the provisions of this Section 3.6 shall
control; and

               (4) the rights of the Beneficial Owners shall be exercised only through the
Depositary and shall be limited to those established by law and agreements between
such Beneficial Owners and the Depositary and/or the Depositary Participants.

Section 3.7 Notices to Holders.

          Whenever a notice or other communication to the Holders is required to be given under this
Agreement, the Company or the Company’s agent shall give such notices and communications to the
Holders and, with respect to any Units registered in the name of a Depositary or the nominee of a
Depositary, the Company or the Company’s agent shall, except as set forth herein, have no
obligations to the Beneficial Owners.

Section 3.8 Appointment of Successor Depositary.

          If any Depositary elects to discontinue its services as securities depositary with respect to
the Units or ceases to be eligible as a “depositary” under the Exchange Act, the Company may, in
its sole discretion, appoint a successor Depositary with respect to the Units.

Section 3.9 Definitive Certificates.

          If (a) the Depositary is at any time unwilling, unable or ineligible to continue as a
“clearing agency” registered under the Exchange Act and a successor Depositary is not appointed by
the Company pursuant to Section 3.8 within 90 days of the date the Company and the Purchase
Contract Agent is so informed in writing thereof, (b) the Company executes and delivers to the
Purchase Contract Agent a Company Order (as defined in the Indenture) to the effect that the Global
Certificates shall be exchangeable for Definitive Certificates or (c) a default by the Company in
respect of its

26

 

obligations under one or more Purchase Contracts has occurred and is continuing, then upon
surrender of the Global Certificates representing the Units by the Depositary, accompanied by
registration instructions, the Company shall cause definitive Certificates to be delivered to
Beneficial Owners in accordance with the instructions of the Depositary. The Company and the
Purchase Contract Agent shall not be liable for any delay in delivery of such instructions and may
conclusively rely on and shall be protected in relying on, such instructions.

Section 3.10 Mutilated, Destroyed, Lost and Stolen Certificates.

          If any mutilated Certificate is surrendered to the Purchase Contract Agent, the Company shall
execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall
authenticate, execute on behalf of the Holder, and deliver in exchange therefor, a new Certificate,
evidencing the same number of Corporate Units or Treasury Units, as the case may be, and bearing a
Certificate number not contemporaneously outstanding.

          If there shall be delivered to the Company and the Purchase Contract Agent (i) evidence to
their satisfaction of the destruction, loss or theft of any Certificate, and (ii) such security or
indemnity as may be required by them to hold each of them and any agent of any of them harmless,
then, in the absence of notice to the Company or to a Responsible Officer of the Purchase Contract
Agent that such Certificate has been acquired by a bona fide purchaser, the Company shall execute
and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate,
execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or
stolen Certificate, a new Certificate, evidencing the same number of Corporate Units or Treasury
Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding.

          Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to
the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a Certificate on or after
the Business Day immediately preceding the earlier of the Purchase Contract Settlement Date or the
Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable
conditions specified above in this Section and receipt of appropriate registration or transfer
instructions from such Holder, the Purchase Contract Agent shall:

               (1) if the Purchase Contract Settlement Date has occurred, deliver the shares
of Common Stock issuable in respect of the Purchase Contracts forming a part of
the Units evidenced by such Certificate; or

               (2) if a Termination Event shall have occurred prior to the Purchase Contract
Settlement Date, transfer the Debt
Securities, the Treasury Portfolio or the Treasury Securities, as the case
may be, evidenced thereby,

27

 

in each case subject to the applicable conditions and in accordance with the applicable provisions
of Article Five hereof.

          Upon the issuance of any new Certificate under this Section, the Company and the Purchase
Contract Agent may require the payment by the Holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other expenses (including the
fees and expenses of the Purchase Contract Agent) connected therewith.

          Every new Certificate issued pursuant to this Section in lieu of any destroyed, lost or stolen
Certificate shall constitute an original additional contractual obligation of the Company and of
the Holder in respect of the Units evidenced thereby, whether or not the destroyed, lost or stolen
Certificate (and the Units evidenced thereby) shall be at any time enforceable by anyone, and shall
be entitled to all the benefits and be subject to all the obligations of this Agreement equally and
proportionately with any and all other Certificates delivered hereunder.

          The provisions of this Section are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Certificates.

Section 3.11 Persons Deemed Owners.

          Prior to due presentment of a Certificate for registration of transfer, the Company and the
Purchase Contract Agent, and any agent of the Company or the Purchase Contract Agent, may treat the
Person in whose name such Certificate is registered as the owner of the Corporate Units or Treasury
Units evidenced thereby, for the purpose of receiving interest payments on the Debt Securities,
receiving Purchase Contract Adjustment Payments, performance of the Purchase Contracts and for all
other purposes whatsoever, whether or not any interest payments on the Debt Securities or the
Purchase Contract Adjustment Payments payable in respect of the Purchase Contracts constituting a
part of the Corporate Units or Treasury Units evidenced thereby shall be overdue and
notwithstanding any notice to the contrary, and neither the Company nor the Purchase Contract
Agent, nor any agent of the Company or the Purchase Contract Agent, shall be affected by notice to
the contrary.

          Notwithstanding the foregoing, with respect to any Global Certificate, nothing contained
herein shall prevent the Company, the Purchase Contract Agent or any agent of the Company or the
Purchase Contract Agent, from giving effect to any written certification, proxy or other
authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such
Global Certificate or impair, as between such Depositary and owners of beneficial interests in such
Global Certificate, the operation of
customary practices governing the exercise of rights of such Depositary (or its nominee) as
Holder of such Global Certificate.

28

 

Section 3.12 Cancellation.

          All Certificates surrendered for delivery of shares of Common Stock on or after the Purchase
Contract Settlement Date, upon the transfer of Debt Securities, the Treasury Portfolio or Treasury
Securities, as the case may be, after the occurrence of a Termination Event or pursuant to an Early
Settlement, or a Collateral Substitution or the recreation of Corporate Units or upon the
registration of a transfer or exchange of a Unit, shall, if surrendered to any Person other than
the Purchase Contract Agent, be delivered to the Purchase Contract Agent and, if not already
cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Purchase
Contract Agent for cancellation any Certificates previously authenticated, executed and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all Certificates so
delivered shall, upon Issuer Order, be promptly cancelled by the Purchase Contract Agent. No
Certificates shall be authenticated, executed on behalf of the Holder and delivered in lieu of or
in exchange for any Certificates cancelled as provided in this Section, except as expressly
permitted by this Agreement. All cancelled Certificates held by the Purchase Contract Agent shall
be disposed of by the Purchase Contract Agent in accordance with its customary procedures.

          If the Company or any Affiliate of the Company shall acquire any Certificate, such acquisition
shall not operate as a cancellation of such Certificate unless and until such Certificate is
delivered to the Purchase Contract Agent cancelled or for cancellation.

Section 3.13 Creation of Treasury Units by Substitution of Treasury Securities.

          A Holder may separate the Debt Securities from the related Purchase Contracts in respect of
such Holder’s Corporate Units by substituting for such Debt Securities Treasury Securities or
security entitlements thereto, pursuant to the Pledge Agreement, in an aggregate principal amount
equal to the aggregate principal amount of such Debt Securities, at any time from and after the
date of this Agreement until 5:00 p.m. (New York City time) on the Election Date by:

               (1) providing notice to the Purchase Contract Agent, substantially in the
form of Exhibit C hereto, of such Holder’s intention to create Treasury Units;

               (2) for each group of 20 Corporate Units from which such Holder wishes to
create Treasury Units, transferring a Treasury Security to the Securities
Intermediary which shall then (y) deposit the Treasury Security with the
Collateral Agent in the Collateral
Account under the Pledge Agreement and instruct the Collateral Agent to hold
such Treasury Security as Collateral under the Pledge Agreement and (z) instruct
the Collateral Agent to release to the Purchase Contract Agent, on behalf of such
Holder, $1,000 principal amount of Debt Securities formerly subject to the Pledge;

29

 

               (3) transferring the related Corporate Units to the Purchase Contract Agent
accompanied by a notice to the Purchase Contract Agent, substantially in the form
of Exhibit D hereto, stating that the Holder has transferred the relevant amount
of Treasury Securities to the Securities Intermediary and requesting that the
Purchase Contract Agent instruct the Collateral Agent to release the Debt
Securities relating to such Corporate Units, whereupon the Purchase Contract Agent
shall promptly give such instruction to the Collateral Agent, substantially in the
form of Exhibit A to the Pledge Agreement; and

               (4) paying to the Collateral Agent any fees or expenses incurred in
connection with the Collateral Substitution;

provided that, Holders may make Collateral Substitutions only in integral multiples of 20 Corporate
Units. Under no circumstances may a Holder of Corporate Units create Treasury Units after the
Election Date.

          The Holders’ right to create Treasury Units as set forth in this Section and the limit of the
preceding sentence shall in no way limit the ability of the Purchase Contract Agent, the Collateral
Agent, the Securities Intermediary or the Remarketing Agent to substitute the Treasury Portfolio
for the Debt Securities then comprising a part of the Corporate Units upon a Successful Remarketing
(other than the Debt Securities of Holders of Corporate Units that have elected not to participate
in the Remarketing).

          Upon receipt of the Treasury Securities described in clause (2) above and the instruction
described in clause (1) above, in accordance with the terms of the Pledge Agreement, the Collateral
Agent shall, under the Pledge Agreement, cause the Securities Intermediary to effect the release of
such Debt Securities from the Pledge to the Purchase Contract Agent, free and clear of the
Company’s security interest therein, and the transfer of such Debt Securities to the Purchase
Contract Agent on behalf of the Holder thereof. Upon receipt thereof, the Purchase Contract Agent
shall promptly:

               (i) cancel the related Corporate Units;

               (ii) transfer the applicable aggregate principal amount of
Debt Securities to the Holder; and

               (iii) authenticate, execute on behalf of such Holder and
deliver a Treasury Unit
Certificate executed by the Company in accordance with
Section 3.3 evidencing the same number of Purchase Contracts as
were evidenced by the cancelled Corporate Units.

30

 

          Holders who elect to separate the Debt Securities from the related Purchase Contracts and to
substitute Treasury Securities for such Debt Securities shall be responsible for any fees or
expenses payable to the Collateral Agent for its services as Collateral Agent in respect of the
substitution, and the Company shall not be responsible for any such fees or expenses.

          In the event a Holder making a Collateral Substitution pursuant to this Section 3.13 fails to
effect a book-entry transfer of the Corporate Units or fails to deliver Corporate Unit Certificates
to the Purchase Contract Agent after depositing Treasury Securities with the Collateral Agent, then
the Debt Securities or Treasury Portfolio Interest, as the case may be, constituting a part of such
Corporate Units, and any interest payments on such Debt Securities or the Treasury Portfolio
Interest, as the case may be, shall be held in the name of the Purchase Contract Agent or its
nominee in trust for the benefit of such Holder, until such Corporate Units are so transferred or
the Corporate Unit Certificates are so delivered, as the case may be, or, with respect to the
Corporate Unit Certificates, such Holder provides evidence satisfactory to the Company and the
Purchase Contract Agent that such Corporate Unit Certificates have been destroyed, lost or stolen,
together with any indemnity that may be required by the Purchase Contract Agent and the Company.

          Except as described in this Sections 3.13 and 5.3, for so long as the Purchase Contract
relating to a Corporate Unit remains in effect, such Corporate Unit shall not be separable into its
constituent parts, and the rights and obligations of the Holder in respect of the Debt Security or
the Treasury Portfolio Interest, as the case may be, and the Purchase Contract comprising such
Corporate Unit may be acquired, and may be transferred and exchanged, only as a Corporate Unit.

Section 3.14 Recreation of Corporate Units.

          A Holder of Treasury Units may recreate Corporate Units at any time until 5:00 p.m. (New York
City time) on the Election Date by:

               (1) providing notice to the Purchase Contract Agent, substantially in the
form of Exhibit C hereto, of such Holder’s intention to create Corporate Units;

               (2) for each Treasury Unit such Holder wishes to substitute, transferring 20
Debt Securities to the Securities Intermediary which shall then (y) deposit such
Debt Securities in the Collateral Account under the Pledge Agreement and instruct
the Collateral
Agent to hold such Debt Securities as Collateral and (z) instruct the
Collateral Agent to release to such Holder the Treasury Security formerly subject
to the Pledge;

               (3) transferring the related Treasury Units to the Purchase Contract Agent
accompanied by a notice to the Purchase Contract Agent, substantially in the form
of Exhibit D hereto, (i) stating

31

 

that the Holder has transferred the relevant
amount of Debt Securities to the Securities Intermediary and (ii) requesting that
the Purchase Contract Agent instruct the Collateral Agent to release the Treasury
Securities relating to such Treasury Units, whereupon the Purchase Contract Agent
shall promptly give such instruction to the Collateral Agent, substantially in the
form of Exhibit C to the Pledge Agreement; and

               (4) paying to the Collateral Agent any fees or expenses incurred in
connection with the recreation of Corporate Units;

provided that, Holders of Treasury Units may recreate Corporate Units in integral multiples of 20
Treasury Units for 20 Corporate Units. Under no circumstance may a Holder of Treasury Units
recreate Corporate Units after the Election Date.

          Upon receipt of the Debt Securities described in clause (1) above and the instruction
described in clause (2) above, in accordance with the terms of the Pledge Agreement, the Collateral
Agent shall cause the Securities Intermediary to effect the release of such Treasury Securities
from the Pledge, free and clear of the Company’s security interest therein, and the transfer of
such Treasury Securities to the Holder thereof. Upon receipt thereof, the Purchase Contract Agent
shall promptly:

               (i) cancel the related Treasury Units; and

               (ii) authenticate, execute on behalf of such Holder and
deliver a Corporate Unit Certificate executed by the Company in
accordance with Section 3.3 evidencing the same number of Purchase
Contracts as were evidenced by the cancelled Treasury Units.

          Holders who elect to recreate Corporate Units shall be responsible for any fees or expenses
payable to the Collateral Agent for its services as Collateral Agent in respect of the
substitution, and the Company shall not be responsible for any such fees or expenses.

          Except as provided in this Section 3.14, for so long as the Purchase Contract relating to a
Treasury Unit remains in effect, such Treasury Unit shall not be separable into its constituent
parts and the rights and obligations of the Holder of such Treasury Unit in respect of the 1/20 of
a Treasury Security and the Purchase Contract
comprising such Treasury Unit may be acquired, and may be transferred and exchanged, only as a
Treasury Unit.

Section 3.15 Transfer of Collateral upon Occurrence of Termination Event.

          Upon the occurrence of a Termination Event and the transfer to the Purchase Contract Agent of
Debt Securities, Treasury Portfolio or Treasury Securities, as the case may be, relating to the
Corporate Units and the Treasury Units, as the case may

32

 

be, pursuant to the terms of the Pledge
Agreement, the Purchase Contract Agent shall request transfer instructions with respect to such
Debt Securities, Treasury Portfolio Interest or Treasury Securities, as the case may be, from each
Holder by written request, substantially in the form of Exhibit E hereto, mailed to such Holder at
its address as it appears in the Corporate Units Register or the Treasury Units Register, as the
case may be.

          Upon book-entry transfer of the Corporate Units or Treasury Units or delivery of a Corporate
Unit Certificate or Treasury Unit Certificate to the Purchase Contract Agent with such transfer
instructions, the Purchase Contract Agent shall transfer such Debt Securities, Treasury Portfolio
Interest or Treasury Securities, as the case may be, relating to such Corporate Units or Treasury
Units, as the case may be, to such Holder by book-entry transfer, or other appropriate procedures,
in accordance with such instructions. In the event a Holder of Corporate Units or Treasury Units
fails to effect such transfer or delivery, such Debt Securities, Treasury Portfolio Interest or
Treasury Securities, as the case may be, relating to such Corporate Units or Treasury Units, as the
case may be, and any interest thereon, shall be held in the name of the Purchase Contract Agent or
its nominee in trust for the benefit of such Holder, until the earlier of:

               (1) such Corporate Units or Treasury Units are transferred or the Corporate
Unit Certificate or Treasury Unit Certificate is surrendered or such Holder
provides satisfactory evidence that such Corporate Unit Certificate or Treasury
Unit Certificate has been destroyed, lost or stolen, together with any indemnity
that may be required by the Purchase Contract Agent and the Company; and

               (2) the expiration of the time period specified in the abandoned property
laws of the relevant State.

Section 3.16 No Consent to Assumption.

          Each Holder of a Unit, by acceptance thereof, shall be deemed expressly to have withheld any
consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase
Contract by the Company or its trustee, receiver, liquidator or a person or entity performing
similar functions in the event that the
Company becomes the debtor under the Bankruptcy Code or subject to other similar state or
federal law providing for reorganization or liquidation.

ARTICLE IV

The Debt Securities

Section 4.1 Interest Payments; Rights to Interest Preserved.

          Each Corporate Unit issued hereunder shall consist of the beneficial ownership by the Holder
of one Debt Security issued pursuant to the Indenture or, if the Corporate Unit shall have been
remarketed by the Remarketing Agent pursuant to the

33

 

Remarketing Agreement, the Treasury Portfolio
Interest, in each case, subject to the Pledge thereof by such Holder under the Pledge Agreement.

          An interest payment on any Debt Security which is paid on any Payment Date or the portion of
the proceeds of a Treasury Portfolio Interest equal to the interest payable on a Debt Security on
the Purchase Contract Settlement Date (such portion the “Treasury Portfolio Return”), as the case
may be, subject to receipt thereof by the Purchase Contract Agent from the Collateral Agent as
provided by the terms of the Pledge Agreement, shall promptly be paid to the Person in whose name
the Corporate Unit Certificate (or one or more Predecessor Corporate Unit Certificates) of which
such Debt Security or the Treasury Portfolio Interest, as the case may be, is a part is registered
at the close of business on the Record Date for such Payment Date or Purchase Contract Settlement
Date, as applicable.

          Each Corporate Unit Certificate evidencing, in part, the Debt Security or the Treasury
Portfolio Interest delivered under this Agreement upon registration of transfer of or in exchange
for or in lieu of any other Corporate Unit Certificate shall carry the right to accrued and unpaid
interest, and the right to accrue interest (and accreted and accreting principal in the case of
non-interest bearing components of the Treasury Portfolio Interest), which rights were carried by
the Debt Security or the Treasury Portfolio Interest, as the case may be, relating to such other
Corporate Unit Certificate.

          In the case of any Corporate Units with respect to which (1) Cash Settlement of the related
Purchase Contract is effected on the fifth Business Day immediately preceding the Purchase Contract
Settlement Date, (2) Early Settlement of the related Purchase Contract is effected on an Early
Settlement Date, (3) Merger Early Settlement of the related Purchase Contract is effected on a
Merger Early Settlement Date or (4) a Collateral Substitution is effected, in each case, on a date
that is after any Record Date and on or prior to the next succeeding Payment Date, the interest
payment on the Debt Security or the Treasury Portfolio Return, as the case may be, relating to such
Corporate Units otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Cash Settlement, Early Settlement, Merger Early Settlement or Collateral
Substitution, as the case may be, and such payment shall, subject
to receipt thereof by the Purchase Contract Agent, be payable to the Person in whose name the
Corporate Unit Certificate (or one or more Predecessor Corporate Unit Certificates) was registered
at the close of business on the corresponding Record Date. Except as otherwise expressly provided
in the immediately preceding sentence, in the case of any Corporate Units with respect to which
Cash Settlement, Early Settlement or Merger Early Settlement of the related Purchase Contract is
effected on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, on
an Early Settlement Date or on a Merger Early Settlement Date, respectively, or with respect to
which a Collateral Substitution has been effected, interest payments on the related Debt Securities
or the Treasury Portfolio Return, as the case may be, that would otherwise be payable after the
fifth Business Day preceding the Purchase Contract Settlement Date, after the Early Settlement
Date, after the Merger Early Settlement Date, or after the Collateral Substitution, respectively,
shall not be payable hereunder to the Holder of such Corporate Units; provided, however, that to
the extent that such Holder continues to hold

34

 

the Separated Debt Security that formerly comprised a
part of such Holder’s Corporate Units, such Holder shall be entitled to receive the interest
payments on such Separated Debt Security, as provided in the Indenture.

Section 4.2 Interest Rate Reset.

          The applicable interest rate borne by the Debt Securities, whether or not part of Corporate
Units, shall be reset to the Reset Rate, pursuant to the Indenture, and will be effective with
respect to all Debt Securities, whether or not then constituting a component of Corporate Units, as
of the Remarketing Settlement Date, in the case of a Successful Remarketing, or, as of the Purchase
Contract Settlement Date, in the event of a Failed Remarketing or in the event there is no
Remarketing pursuant to clause (c) of the definition of Reset Rate in the Indenture Officer’s
Certificate.

Section 4.3 Notice and Voting.

          The Purchase Contract Agent is entitled to exercise the voting and any other consensual rights
pertaining to the Pledged Debt Securities, but only to the extent instructed in writing by the
Holders as described below. Upon receipt of notice of any meeting at which holders of Debt
Securities are entitled to vote or upon any solicitation of consents, waivers or proxies of holders
of Debt Securities, the Purchase Contract Agent shall, as soon as practicable thereafter, mail to
the Holders of Corporate Units a notice:

               (1) containing such information as is contained in the notice or
solicitation;

               (2) stating that each Holder on the record date set by the Purchase Contract
Agent therefor (which, to the extent possible, shall be the same date as the
record date for determining the
holders of Debt Securities entitled to vote) shall be entitled to instruct
the Purchase Contract Agent as to the exercise of the voting rights pertaining to
such Debt Securities relating to their Corporate Units; and

               (3) stating the manner in which such instructions may be given.

          Upon the written request of the Holders of Corporate Units on such record date received by the
Purchase Contract Agent at least six calendar days prior to such meeting or by the expiration date
of any such solicitation, the Purchase Contract Agent shall endeavor insofar as practicable to vote
or cause to be voted, in accordance with the instructions set forth in such requests, the maximum
principal amount of Debt Securities as to which any particular voting instructions are received. In
the absence of specific instructions from the Holder of Corporate Units, the Purchase Contract
Agent shall abstain from voting the Debt Securities relating such Corporate Units. The Company
hereby agrees, if applicable, to solicit Holders of Corporate Units to timely instruct the Purchase
Contract Agent in order to enable the Purchase Contract Agent to vote such Debt Securities.

ARTICLE V

The Purchase Contracts; The Remarketing

Section 5.1 Purchase of Shares of Common Stock.

          Each Purchase Contract shall, unless a Termination Event has occurred as set forth in Section
5.7, an Early Settlement has occurred in accordance with Section 5.9 or a Merger Early Settlement
has occurred in accordance with Section 5.10, obligate the Holder of the related Units to purchase,
and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated
Amount (the “Purchase Price”), a number of newly issued shares of Common Stock equal to the
Settlement Rate then in effect. The “Settlement Rate” is equal to:

               (1) if the Applicable Closing Price per share is equal to or greater than
$___ (the “Threshold Appreciation Price”),
___ shares of Common Stock per
Purchase Contract;

               (2) if the Applicable Closing Price per share is less than the Threshold
Appreciation Price, but greater than $___ (the “Reference Price”), the number of shares of Common Stock determined by dividing the Stated Amount by the Applicable
Closing Price; and

               (3) if the Applicable Closing Price per share is less than or equal to the
Reference Price, ___ shares of Common Stock per Purchase Contract,

in each case subject to adjustment as provided in Section 5.5 (and in each case rounded upward or
downward to the nearest 1/10,000th of a share).

          Promptly after the calculation of the Settlement Rate and the Applicable Closing Price, the
Company shall give the Purchase Contract Agent notice thereof. All calculations and determinations
of the Settlement Rate and the Applicable Closing Price shall be made by the Company or its agent
based on their good faith calculations, and the Purchase Contract Agent shall have no
responsibility with respect thereto.

          As provided in Section 5.12, no fractional shares of Common Stock will be issued upon
settlement of Purchase Contracts.

          The “Applicable Closing Price” means the average of the Closing Prices per share of Common
Stock on each of the 20 consecutive Trading Days ending on the third Trading Day immediately
preceding the Purchase Contract Settlement Date, or in the case of the exercise of a Merger Early
Settlement right, the Cash Merger Date.

36

 

          The “Closing Price” per share of the Common Stock on any date of determination means:

               (1) the closing sale price (or, if no closing price is reported, the last
reported sale price) per share of the Common Stock on the New York Stock Exchange,
Inc. on such date;

               (2) if the Common Stock is not listed for trading on the New York Stock
Exchange, Inc. on any such date, the closing sale price per share as reported in
the composite transactions for the principal United States securities exchange on
which the Common Stock is so listed;

               (3) if the Common Stock is not so listed on a United States national or
regional securities exchange, the closing sale price per share as reported by The
Nasdaq Stock Market;

               (4) if the Common Stock is not so reported, the last quoted bid price per
share for the Common Stock in the over-the-counter market as reported by the
National Quotation Bureau or similar organization; or

               (5) if such bid price is not available, the average of the mid-point of the
last bid and ask prices per share of the Common Stock on such date from at least
three nationally recognized independent investment banking firms retained for this
purpose by the Company.

          A “Trading Day” means a day on which the Common Stock (1) is not suspended from trading on any
national or regional securities exchange or association or over-the-counter market at the close of
business and (2) has traded at least once on the
national or regional securities exchange or association or the over-the-counter market that is
the primary market for the trading of the Common Stock.

          Each Holder of a Corporate Unit or a Treasury Unit, by its acceptance thereof:

               (1) irrevocably authorizes the Purchase Contract Agent to enter into and
perform the related Purchase Contract on its behalf as its attorney-in-fact
(including the execution of Certificates on behalf of such Holder as such Holder’s
attorney-in-fact);

               (2) agrees to be bound by the terms and provisions thereof;

               (3) covenants and agrees to perform its obligations under such Purchase
Contracts;

37

 

               (4) consents to the provisions hereof;

               (5) irrevocably authorizes the Purchase Contract Agent to enter into and
perform this Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact; and

               (6) consents to and agrees to be bound by the Pledge of the Debt Securities
or the Treasury Securities pursuant to the Pledge Agreement; and

               (7) agrees to treat itself as the owner of the related Debt Securities,
Treasury Portfolio Interest or Treasury securities, as the case may be, in each
case for U.S. Federal, state and local income and franchise tax purposes;

provided that, upon a Termination Event, the rights of the Holder of such Unit under the Purchase
Contract may be enforced without regard to any other rights or obligations. Each Holder of a
Corporate Unit or a Treasury Unit, by its acceptance thereof, further covenants and agrees, that to
the extent and in the manner provided in Section 5.3 and the Pledge Agreement, but subject to the
terms thereof, proceeds from the Remarketing of the Debt Securities (less the Remarketing Fee
payable to the Remarketing Agent pursuant to the Remarketing Agreement), the Treasury Portfolio
Interest or the Treasury Securities at maturity, as the case may be, to be paid upon settlement of
such Holder’s obligations to purchase Common Stock under the Purchase Contract, shall be paid on
the Purchase Contract Settlement Date by the Collateral Agent to the Company in satisfaction of
such Holder’s obligations under such Purchase Contract and such Holder shall acquire no right,
title or interest in such payments.

          Upon registration of transfer of a Certificate, the transferee shall be bound (without the
necessity of any other action on the part of such transferee) by the terms of this Agreement, the
Purchase Contracts relating to such Certificate and the Pledge
Agreement and the transferor shall be released from the obligations under this Agreement, the
Purchase Contracts relating to the Certificates so transferred and the Pledge Agreement. The
Company covenants and agrees, and each Holder of a Certificate, by its acceptance thereof, likewise
covenants and agrees, to be bound by the provisions of this paragraph.

Section 5.2 Purchase Contract Adjustment Payments.

          The Company shall pay, on each Payment Date, the Purchase Contract Adjustment Payments payable
in respect of each Purchase Contract to the Person in whose name a Certificate (or one or more
Predecessor Certificates) is registered at the close of business on the Record Date next preceding
such Payment Date in such coin or currency of the United States as at the time of payment shall be
legal tender for the payment of public and private debts. The Purchase Contract Adjustment Payments
will be payable at the office of the Purchase Contract Agent in The City of New York maintained for
that purpose or, at the option of the Company, by wire transfer or by

38

 

check mailed to the address
of the Person entitled thereto at such Person’s address as it appears on the Corporate Units
Register or Treasury Units Register.

          Upon the occurrence of a Termination Event, the Company’s obligation to pay Purchase Contract
Adjustment Payments (including any accrued Purchase Contract Adjustment Payments) shall cease.

          Each Certificate delivered under this Agreement upon registration of transfer of or in
exchange for or in lieu of (including as a result of a Collateral Substitution or the recreation of
Corporate Units) any other Certificate shall carry the right to accrued and unpaid Purchase
Contract Adjustment Payments, and the right to accrue Purchase Contract Adjustment Payments, which
rights were carried by the Purchase Contracts relating to such other Certificates from the date of
issuance to and excluding, the Purchase Contract Settlement Date, unless such Purchase Contracts
have been settled earlier pursuant to this Agreement.

          In the case of any Units with respect to which (1) Cash Settlement of the related Purchase
Contract is effected on the fifth Business Day immediately preceding the Purchase Contract
Settlement Date, (2) Early Settlement of the related Purchase Contract is effected on an Early
Settlement Date or (3) Merger Early Settlement of the related Purchase Contract is effected on a
Merger Early Settlement Date, in each case, on a date that is after any Record Date and on or prior
to the next succeeding Payment Date, Purchase Contract Adjustment Payments otherwise payable on
such Payment Date shall be payable on such Payment Date notwithstanding such Cash Settlement, Early
Settlement or Merger Early Settlement, as the case may be, and such Purchase Contract Adjustment
Payments shall be paid to the Person in whose name the Certificate evidencing such Units (or one or
more Predecessor Certificates) is registered at the close of business on such Record Date. Except
as otherwise expressly provided in the immediately preceding sentence, in the case of any Units
with respect to which Cash
Settlement, Early Settlement or Merger Early Settlement of the related Purchase Contract is
effected on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, an
Early Settlement Date or a Merger Early Settlement Date, respectively, Purchase Contract Adjustment
Payments that would otherwise be payable after the fifth Business Day preceding the Purchase
Contract Settlement Date, after the Early Settlement Date or after the Merger Early Settlement
Date, respectively, with respect to such Purchase Contract shall not be payable.

          Promptly after the calculation of any adjustment to the Purchase Contract Adjustment Payments
arising from a Reset Transaction, the Company shall give the Purchase Contract Agent notice
thereof. All calculations and determinations of the Adjusted Purchase Contract Adjustment Payment
Rate shall be made by the Company or its agent in good faith and the Purchase Contract Agent shall
have no responsibility with respect thereto. The Purchase Contract Agent shall not at any time be
under any duty or responsibility to any Holder of Units to determine whether any facts exist which
may require any adjustment to the Purchase Contract Adjustment Payments, or with respect to the
nature or extent or calculation of any such adjustment when made, or with respect to the method
employed in making the same.

39

 

Section 5.3 Payment of Purchase Price; Remarketing.

               (a) Unless a Termination Event has occurred or a Holder has settled the related Purchase
Contract through a Cash Settlement pursuant to Section 5.8, an Early Settlement pursuant to Section
5.9 or a Merger Early Settlement pursuant to Section 5.10, the settlement of the Purchase Contract
relating to a Unit will be made by Remarketing in accordance with this Section 5.3.

               (b) The Company shall engage                     , or another nationally recognized investment
bank, to act as Remarketing Agent (the “Remarketing Agent”) pursuant to the Remarketing Agreement
to remarket (1) the Pledged Debt Securities comprising part of the Corporate Units, other than
those Pledged Debt Securities of Holders that have elected not to participate in the Remarketing
pursuant to Section 5.3(e) below, and (2) the Separated Debt Securities of holders of Separated
Debt Securities that have elected to participate in the Remarketing
pursuant to paragraph ___ of
the Indenture Officer’s Certificate and Section
___ of the Pledge Agreement (the Debt Securities
described in clauses (1) and (2) collectively being referred to as the “Remarketing Debt
Securities”) pursuant to the Remarketing Procedures.

                    On the seventh Business Day prior to the Initial Remarketing Date, the Company shall give
notice of Remarketing in an Authorized Newspaper, including the specific U.S. Treasury security or
securities (including the CUSIP number and/or the principal terms of such Treasury security or
securities) that must be delivered by Holders of Corporate Units that elect not to participate in
the Remarketing pursuant to Section 5.3(e) below, no later than 5:00 p.m. (New York City time) on
the Election Date. Not later than 15 calendar days nor more than 30 calendar days prior to the
Initial
Remarketing Date, the Company shall request DTC (or any successor Depositary), to notify its
Beneficial Owners or Depositary Participants holding Corporate Units or Separate Debt Securities of
the impending Remarketing.

                    The Purchase Contract Agent shall notify, by 11:00 a.m. (New York City time), on the Business
Day immediately preceding the Initial Remarketing Date, the Remarketing Agent, the Collateral
Agent, the Trustee and the Company, by use of a notice substantially in the form of Exhibit G
hereto, of the aggregate principal amount of Pledged Debt Securities of Corporate Unit Holders to
be remarketed on the Initial Remarketing Date or Subsequent Remarketing Date, as applicable, and
the Collateral Agent, pursuant to the Pledge Agreement, having separately notified the Remarketing
Agent, the Trustee and the Company of the aggregate principal amount of Separated Debt Securities
to be included on the Initial Remarketing Date or Subsequent Remarketing Date, as applicable, by
11:00 a.m. (New York City time), on the Business Day immediately preceding the Initial Remarketing
Date, shall concurrently therewith, pursuant to the Pledge Agreement, deliver for Remarketing to
the Remarketing Agent all Remarketing Debt Securities. Upon receipt of such notice from the
Purchase Contract Agent and the Collateral Agent and such Remarketing Debt Securities from the
Collateral Agent, the Remarketing Agent, pursuant to the Remarketing Agreement, will, use its
commercially reasonable efforts to remarket such

40

 

Remarketing Debt Securities on such date pursuant
to the Remarketing Procedures and the Remarketing Agreement.

                    If there has been a Successful Initial Remarketing or a Successful Subsequent Remarketing, the
Remarketing Agent will on the Remarketing Date of such Remarketing (i) deduct and retain for itself
as the remarketing fee for itself an amount not exceeding [ ] basis points ([ ]%) of the
principal amount of each remarketed Remarketing Debt Security (the “Remarketing Fee”), (ii) use the
remaining proceeds attributable to the Pledged Debt Securities from such Successful Remarketing to
purchase the appropriate U.S. Treasury securities (the “Treasury Portfolio” and the related
interest in the Treasury Portfolio applicable to a Corporate Unit, the “Treasury Portfolio
Interest”) with the CUSIP numbers, if any, selected by Remarketing Agent, described in clauses
(1)(i) and (2)(i) of the definition of Remarketing Value related to the Debt Securities of Holders
of Corporate Units that were remarketed, (iii) if any Separated Debt Securities were remarketed,
remit to the Collateral Agent, along with notification thereof, for payment to the holders of such
Separated Debt Securities sold in the Remarketing the remaining proceeds from such Successful
Remarketing equal to the amounts described in clauses (1)(ii) and (2)(ii) of the definition of
Remarketing Value and (iv) if there then remains any proceeds from such Successful Remarketing,
after the application of such proceeds as set forth in clauses (i) through (iii) above of this
sentence, then remit, along with notification thereof, any such remaining proceeds to the Purchase
Contract Agent for the benefit of holders of the remarketed Debt Securities and to the Collateral
Agent for the benefit of the holders of such Separated Debt Securities, on a pro rata basis,
provided, however, that if such Successful Remarketing is consummated after 4:30 p.m. (New York
City time) on such Remarketing Date and, despite using its commercially reasonable efforts, the
Remarketing Agent cannot cause the applications of the proceeds specified above to occur on such
Remarketing Date, then the Remarketing
Agent may make such applications and remittances on the next succeeding Business Day. Holders
of Remarketing Debt Securities that are so remarketed will not otherwise be responsible for the
payment of any remarketing fee or expenses in connection with the Remarketing. On the Remarketing
Settlement Date, the Remarketing Agent shall deliver the Treasury Portfolio to the Collateral
Agent. The Collateral Agent, for the benefit of the Company, will thereupon apply such Treasury
Portfolio, in accordance with the Pledge Agreement, to secure such Holders’ obligations under the
Purchase Contracts.

                    In the event that all or any portion of the Pledged Treasury Portfolio Interest matures before
the Purchase Contract Settlement Date, the Collateral Agent shall invest the proceeds therefrom in
Permitted Investments in accordance with the Pledge Agreement. The Collateral Agent shall cause the
Securities Intermediary to remit, on the Purchase Contract Settlement Date, a portion of the
proceeds of the maturing Pledged Treasury Portfolio Interest and of the investment earnings from
the related investment in Permitted Investments, in each case, in an amount equal to the Treasury
Portfolio Return to the Purchase Contract Agent for the benefit of the Holders of the related
Corporate Units when received. Without receiving any instruction from any such Holder of Corporate
Units, the Collateral Agent shall apply, on the Purchase Contract Settlement Date, the proceeds of
the maturing Pledged Treasury Portfolio Interest and of the investment earnings from the related
investment in Permitted

41

 

Investments in an aggregate amount equal to the aggregate Purchase Price
applicable to such Corporate Units to satisfy in full such Holder’s obligations to pay the Purchase
Price to purchase the shares of Common Stock under the related Purchase Contracts on the Purchase
Contract Settlement Date. In the event the sum of the proceeds from the related Pledged Treasury
Portfolio Interest and the investment earnings from the related investment in Permitted Investments
exceeds the sum of the related Treasury Portfolio Return and the aggregate Purchase Price of the
Purchase Contracts being settled thereby, the Collateral Agent shall instruct the Securities
Intermediary to distribute such excess, when received, to the Purchase Contract Agent for
distribution to the Holders whose Purchase Contracts were settled with such proceeds, on a pro rata
basis.

                    If, by 4:00 p.m. (New York City time), on the ninth Business Day preceding the Purchase
Contract Settlement Date, the Remarketing Agent, despite using its commercially reasonable efforts,
has been and is unable to remarket all of the Remarketing Debt Securities tendered for purchase at
a price equal to at least the Remarketing Value, the Remarketing Agent shall Transfer to the
Collateral Agent, along with notification thereof, by the sixth Business Day preceding the Purchase
Contract Settlement Date, the Pledged Debt Securities that that were to be remarketed in the
Initial or Subsequent Remarketing, whereupon the Collateral Agent shall, for the benefit of the
Company, apply such Pledged Debt Securities, to secure the obligation of the related Holders of
Corporate Units to purchase Common Stock under the related Purchase Contracts.

               (c) Unless a Termination Event has occurred or a Holder has settled the related Purchase
Contract through a Cash Settlement, an Early Settlement or a Merger Early Settlement, or a
Successful Initial Remarketing or a Successful Subsequent Remarketing has occurred, such Holder
shall be deemed to have consented to the
Remarketing of such Holder’s Pledged Debt Securities in the Final Remarketing on the Final
Remarketing Date. The Purchase Contract Agent, shall by 11:00 a.m. (New York City time), on the
Business Day immediately preceding the Final Remarketing Date, notify the Remarketing Agent, the
Collateral Agent, the Trustee and the Company, by use of a notice substantially in the form of
Exhibit G hereto, of such event and of the aggregate principal amount of Pledged Debt Securities of
Corporate Unit Holders to be remarketed on the Final Remarketing Date, whereupon the Collateral
Agent, shall concurrently therewith, without any instruction from such Holder of Corporate Units
with respect to their Pledged Debt Securities, transfer the Remarketing Debt Securities to the
Remarketing Agent for Remarketing. Upon receiving such Remarketing Debt Securities, the Remarketing
Agent, pursuant to the terms of the Remarketing Agreement, will use its commercially reasonable
efforts to remarket such Remarketing Debt Securities on the Final Remarketing Date.

                    If a Successful Final Remarketing shall have occurred, the Remarketing Agent will on the
Remarketing Date (i) deduct and retain for itself the Remarketing Fee, pursuant to the Remarketing
Agreement, (ii) cause the remaining proceeds of the Remarketing with respect to the Pledged Debt
Securities in an amount equal to the aggregate principal amount of such Debt Securities to be
delivered to the Collateral Agent, on the Remarketing Settlement Date, (iii) if any Separated Debt

42

 

Securities were remarketed, remit, along with notification thereof, to the Collateral Agent for
payment to the holders of such Separated Debt Securities sold in the Remarketing the remaining
proceeds from such Successful Remarketing attributable to the Separated Debt Securities in an
amount equal to the principal amount of such Debt Securities and (iv) if there remains any proceeds
from such Successful Remarketing, after the application of such proceeds as set forth in clauses
(i) through (iv) of this sentence, then remit, along with notification thereof, such remaining
proceeds to the Purchase Contract Agent for the benefit of the holders of the Pledged Debt
Securities and to the Collateral Agent for the benefit of holders of Separated Debt Securities, on
a pro rata basis, provided, however, that if such Successful Remarketing is consummated after 4:30
p.m. (New York City time) on such Remarketing Date and, despite using its commercially reasonable
efforts, the Remarketing Agent cannot cause the applications of the proceeds specified above to
occur on such Remarketing Date, then the Remarketing Agent may make such applications and
remittances on the next succeeding Business Day. Holders of the Remarketing Debt Securities that
are so remarketed will not otherwise be responsible for the payment of any remarketing fee or
expenses in connection with the Remarketing. The Purchase Contract Agent shall give written
directions to the Collateral Agent, and the Collateral Agent shall instruct the Securities
Intermediary, to apply a portion of the Proceeds with respect to the Pledged Debt Securities from
such Remarketing, on the Purchase Contract Settlement Date, equal to the aggregate principal amount
of such Pledged Debt Securities to satisfy in full the obligations of such Holders of Corporate
Units to pay the Purchase Price to purchase the shares of Common Stock under the related Purchase
Contracts.

                    If, (1) by 4:00 p.m. (New York City time), on the Final Remarketing Date, despite using its
commercially reasonable efforts, the Remarketing Agent cannot remarket the Debt Securities included
in the Remarketing at a price equal to
at least the Remarketing Value, or (2) the Remarketing Agent has determined that the
Remarketing may not be consummated as contemplated herein and by the Remarketing Procedures under
applicable law, the Remarketing will be deemed to have failed (a “Failed Remarketing”). If a Failed
Remarketing occurs, the Remarketing Agent will, pursuant to the Remarketing Agreement, promptly
advise the Trustee, the Purchase Contract Agent, the Collateral Agent, the Company and the
Depositary that a Failed Remarketing has occurred. The Collateral Agent, under the Pledge Agreement
and for the benefit, and on behalf, of the Company, may exercise its rights as a secured party with
respect to such Pledged Debt Securities, including those actions specified in paragraph (d) below;
provided that, if upon a Failed Remarketing, the Collateral Agent exercises such rights for the
benefit of the Company with respect to such Pledged Debt Securities, any accumulated and unpaid
interest on such Debt Securities will become payable by the Company to the Purchase Contract Agent
for payment to the Holders of the Corporate Units to which such Pledged Debt Securities relate.
Such payment will be made by the Company on or prior to 11:00 a.m. (New York City time), on the
Purchase Contract Settlement Date in lawful money of the United States by certified or cashiers’
check or wire transfer in immediately available funds payable to or upon the order of the Purchase
Contract Agent. The Company will cause a notice of any Failed Remarketing to be sent to the holders
of all Debt Securities and to be published in an Authorized Newspaper, in

43

 

each case, no later than
on the Business Day immediately preceding the Purchase Contract Settlement Date.

               (d) With respect to any Pledged Debt Securities which are subject of a Failed Remarketing, the
Collateral Agent, for the benefit of the Company, and upon written direction of the Company as
provided in the Pledge Agreement, reserves all of its rights as a secured party with respect
thereto and, subject to applicable law and paragraph (e) below, may (i) retain such Debt Securities
in full satisfaction of the Holders’ obligations under the related Purchase Contracts or (ii) sell
such Debt Securities in one or more public or private sales.

               (e) A Holder of Corporate Units may elect not to participate in the Remarketing by creating
Treasury Units by notifying the Purchase Contract Agent of such election and complying with the
procedures for creating Treasury Units set forth in Section 3.13 until 5:00 p.m. (New York City
time) on the Election Date. A Holder that does not so create Treasury Units by delivering the
Treasury Security or Treasury Securities pursuant to this paragraph and Section 3.13 shall be
deemed to have elected to participate in any Remarketing.

               (f) In the event that all or any portion of the Pledged Treasury Securities of Treasury Units
matures before the Purchase Contract Settlement Date, the Collateral Agent shall invest the
proceeds therefrom in Permitted Investments in accordance with the Pledge Agreement.

                    Without receiving any instruction from any such Holder of Treasury Units, the Collateral Agent
shall apply, on the Purchase Contract Settlement Date, the proceeds of the maturing Pledged
Treasury Securities and of the investment earnings from the related investment in Permitted
Investments, in each case, in an amount
equal to the aggregate Purchase Price applicable to such Treasury Units to satisfy in full
such Holder’s obligations to pay the Purchase Price to purchase the shares of Common Stock under
the related Purchase Contracts on the Purchase Contract Settlement Date.

                    In the event the sum of the proceeds from the related Pledged Treasury Securities and the
investment earnings from the related investment in Permitted Investments exceeds the aggregate
Purchase Price of the Purchase Contracts being settled thereby, the Collateral Agent shall instruct
the Securities Intermediary to distribute such excess, when received, to the Purchase Contract
Agent for distribution to the Holders whose Purchase Contracts were settled with such proceeds, on
a pro rata basis.

               (g) Any distributions to Holders of excess funds and interest described in paragraphs (b), (c)
and (f) above shall be payable at the office of the Purchase Contract Agent in The City of New York
maintained for that purpose or, at the option of the Holder, or the holder of Separated Debt
Securities, as applicable, by check mailed to the address of the Person entitled thereto at such
address as it appears on the Register or by wire transfer to an account specified by the Holder, or
the holder of Separated Debt Securities, as applicable.

44

 

               (h) The obligations of each Holder to pay the Purchase Price are non-recourse obligations and
except to the extent paid by Cash Settlement, Early Settlement or Merger Early Settlement, are
payable solely out of the proceeds of any Collateral pledged to secure the obligations of the
Holders, and in no event shall Holders be liable for any deficiency between such payments and the
Purchase Price.

               (i) Notwithstanding anything to the contrary herein, the Company shall not be obligated to
issue any Common Stock in respect of a Purchase Contract or deliver any certificates therefor to
the Holder of the related Units unless the Company shall have received payment in full of the
aggregate Purchase Price for the shares of Common Stock to be purchased thereunder by such Holder
in the manner herein set forth, which payment, in the case of Corporate Units upon the occurrence
of a Failed Remarketing, shall occur by the resale of Pledged Debt Securities or foreclosure on and
retention of such Pledged Debt Securities.

Section 5.4 Issuance of Shares of Common Stock.

               (a) Unless a Termination Event shall have occurred on or prior to the Purchase Contract
Settlement Date, the applicable Early Settlement Date or the Merger Early Settlement Date, upon its
receipt of payment in full of the Purchase Price for the shares of Common Stock purchased by
Holders pursuant to the provisions of this Article and subject to Section 5.5(b), the Company shall
issue and deposit with the Company’s transfer agent and registrar for its Common Stock (the “Common
Stock Transfer Agent”), for the benefit of the Holders of the Outstanding Units, one or more
certificates representing the newly issued shares of Common Stock registered in the name of the
Purchase Contract
Agent (or its nominee) as custodian for the Holders (such
certificates for shares of Common Stock, together with any dividends or distributions for
which a record date and payment date for such dividend or distribution has occurred after the
applicable Early Settlement Date, the Merger Early Settlement Date or the Purchase Contract
Settlement Date, as the case may be, being hereinafter referred to as the “Purchase Contract
Settlement Fund”) to which the Holders are entitled hereunder. The Company shall furnish to the
Purchase Contract Agent the name and address of the Common Stock Transfer Agent and of any change
thereof.

               (b) Upon surrender of a Certificate to the Purchase Contract Agent on or after the applicable
Early Settlement Date, the Merger Early Settlement Date or the Purchase Contract Settlement Date,
as the case may be, together with settlement instructions thereon duly completed and executed, the
Holder of such Certificate shall be entitled to receive in exchange therefor a certificate
representing that number of whole shares of Common Stock which such Holder is entitled to receive
pursuant to the provisions of this Article Five (after taking into account all Units then held by
such Holder), together with cash in lieu of fractional shares as provided in Section 5.12 and any
dividends or distributions with respect to such shares constituting part of the Purchase Contract
Settlement Fund, but without any interest thereon (or, if such Certificate is not surrendered to
the Purchase Contract Agent; or if no such instructions are given to the Purchase Contract Agent by
the Holder, the Common Stock Agent shall hold such certificate representing shares of Common Stock,
and the Purchase
Contract

45

 

Agent shall hold such cash in lieu of fractional shares and dividends or
distributions, as applicable, in the name of the Purchase Contract Agent or its nominee in trust
for the benefit of such Holder until the expiration of the time period specified in the abandoned
property laws of the relevant state, following which the Purchase Contract Agent shall cause such
cash to be delivered to such Holders), and the Certificate so surrendered shall forthwith be
cancelled. Such shares shall be registered by the Common Stock Transfer Agent in the Company’s
register for its Common Stock and in accordance with its customary procedures for issuance of such
Common Stock, in the name of the Holder or the Holder’s designee as specified in the settlement
instructions provided by the Holder to the Purchase Contract Agent and forwarded by the Purchase
Contract Agent to the Common Stock Transfer Agent. If any shares of Common Stock issued in respect
of a Purchase Contract are to be registered to a Person other than the Person in whose name the
Certificate evidencing such Purchase Contract is registered, no such registration shall be made
unless the Person requesting such registration has paid any transfer and other taxes required by
reason of such registration in a name other than that of the registered Holder of the Certificate
evidencing such Purchase Contract or has established to the satisfaction of the Company that such
tax either has been paid or is not payable.

Section 5.5 Adjustment of Settlement Rate and Early Settlement Rate.

               (a) Adjustments for Dividends, Distributions, Stock Splits, Etc.

               (1) In case the Company shall pay or make a dividend or other distribution on
the Common Stock in Common
Stock, the Settlement Rate in effect or the Early Settlement Rate, as
applicable, in effect at the opening of business on the Business Day following the
date fixed for the determination of shareholders entitled to receive such dividend
or other distribution shall be increased by dividing such Settlement Rate by a
fraction of which:

               (i) the numerator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for
such determination; and

               (ii) the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend
or other distribution,

such increase to become effective immediately after the opening of business on the day
following the date fixed for such determination. For the purposes of this paragraph (1),
the number of shares of Common Stock at any time outstanding shall not include shares held
in the treasury of the Company but shall include any shares issuable in respect of any
scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will
not pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

46

 

               (2) In case the Company shall issue rights, options or warrants to all
holders of Common Stock (not being available on an equivalent basis to Holders of
the Units upon settlement of the Purchase Contracts relating to such Units)
entitling them, for a period expiring within 45 days after the record date for the
determination of shareholders entitled to receive such rights, options or
warrants, to subscribe for or purchase shares of Common Stock at a price per share
less than the Current Market Price per share of Common Stock on the date fixed for
the determination of shareholders entitled to receive such rights, options or
warrants (other than pursuant to a dividend reinvestment plan), the Settlement
Rate or the Early Settlement Rate, as applicable, in effect at the opening of
business on the day following the date fixed for such determination shall be
increased by dividing such Settlement Rate or the Early Settlement Rate, as
applicable, by a fraction of which:

               (i) the numerator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for
such determination plus the number of shares of Common Stock which
the aggregate of the offering price of the total number of shares
of Common Stock so offered for subscription or purchase would
purchase at such Current Market Price; and

               (ii) the denominator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for
such determination plus the number of shares of Common Stock so
offered for subscription or purchase,

such increase to become effective immediately after the opening of
business on the day following the date fixed for such determination. For
the purposes of this paragraph (2), the number of shares of Common Stock
at any time outstanding shall not include shares held in the treasury of
the Company but shall include any shares issuable in respect of any scrip
certificates issued in lieu of fractions of shares of Common Stock. The
Company shall not issue any such rights, options or warrants in
respect of shares of Common Stock held in the treasury of the Company.

               (3) In case outstanding shares of Common Stock shall be subdivided or split
into a greater number of shares of Common Stock, the Settlement Rate or the Early
Settlement Rate, as applicable, in effect at the opening of business on the day
following the day upon which such subdivision or split becomes effective shall be
proportionately increased, and, conversely, in case outstanding shares of
Common
Stock shall each be combined into a smaller number of shares of

47

 

Common Stock, the
Settlement Rate or the Early Settlement Rate, as applicable, in effect at the
opening of business on the day following the day upon which such combination
becomes effective shall be proportionately reduced, such increase or reduction, as
the case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision, split or combination
becomes effective.

               (4) In case the Company shall, by dividend or otherwise, distribute to all
holders of Common Stock evidences of its indebtedness or assets (including
securities, but excluding any rights, options or warrants referred to in paragraph
(2) of this Section 5.5(a), any dividend or distribution paid exclusively in cash
and any dividend or distribution referred to in paragraph (1) of this Section
5.5(a)), the Settlement Rate or the Early Settlement Rate, as applicable, in
effect, shall be adjusted so that the same shall equal the rate determined by
dividing the Settlement Rate or the Early Settlement Rate, as applicable, in
effect immediately prior to the close of business on the date fixed for the
determination of shareholders entitled to receive such distribution by a fraction
of which:

               (i) the numerator shall be the Current Market Price per share
of Common Stock on
the date fixed for such determination less the then fair
market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board
Resolution) of the portion of the assets or evidences of
indebtedness so distributed applicable to one share of Common
Stock; and

               (ii) the denominator shall be such Current Market Price per
share of Common Stock,

such adjustment to become effective immediately prior to the opening of
business on the day following the date fixed for the determination of
shareholders entitled to receive such distribution. In any case in which
this paragraph (4) is applicable, paragraph (2) of this Section 5.5(a)
shall not be applicable.

               (5) In case the Company shall, by dividend or otherwise, distribute to all
holders of Common Stock (I) cash (excluding any cash that is distributed in a
Reorganization Event to which Section 5.5(b) applies or as part of a distribution
referred to in paragraph (4) of this Section 5.5(a)) in an aggregate amount that,
combined together with the aggregate amount of any other distributions to all
holders of Common Stock made exclusively in cash (other than in connection with a
Reorganization Event) within the 12 months preceding the date of

48

 

payment of such
distribution and in respect of which no adjustment pursuant to this paragraph (5)
or paragraph (6) of this Section has been made and (II) the aggregate of any cash
plus the fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution) of
consideration payable in respect of any tender or exchange offer by the Company or
any of its subsidiaries for all or any portion of Common Stock concluded within
the 12 months preceding the date of payment of the distribution described in
Clause (I) above and in respect of which no adjustment pursuant to this paragraph
(5) or paragraph (4) or paragraph (6) of this Section 5.5(a) has been made,
exceeds 15% of the product of the Current Market Price per share of Common Stock
on the date for the determination of holders of shares of Common Stock entitled to
receive such distribution times the number of shares of Common Stock outstanding
on such date, then, and in each such case, immediately after the close of business
on such date for determination, the Settlement Rate or Early Settlement Rate, as
applicable, in effect, shall be increased so that the same shall equal the rate
determined by dividing the Settlement Rate or Early Settlement Rate, as
applicable, in effect immediately prior to the close of business on the date fixed
for determination of the shareholders entitled to receive such distribution by a
fraction of which:

               (i) the numerator shall be equal to the Current Market Price
per share of the Common Stock on the date fixed for such
determination less an amount equal to the quotient of (x) the
combined amount distributed or payable in the transactions
described in clauses (I) and (II) above divided by (y) the number
of shares of Common Stock outstanding on such date for
determination; and

               (ii) the denominator shall be equal to the Current Market
Price per share of Common Stock on such date for determination.

               (6) In case a tender or exchange offer made by the Company or any subsidiary
of the Company for all or any portion of Common Stock shall expire and such tender
or exchange offer (as amended upon the expiration thereof) shall require the
payment to shareholders (based on the acceptance (up to any maximum specified in
the terms of the tender or exchange offer) of Purchased Shares) of (I) an
aggregate consideration having a fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution) that combined together with the aggregate of the cash plus the fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a Board Resolution), as of the expiration of such
tender or exchange offer, of

49

 

consideration payable in respect of any other tender
or exchange offer, by the Company or any subsidiary of the Company for all or any
portion of the Common Stock expiring within the 12 months preceding the expiration
of such tender or exchange offer and in respect of which no adjustment pursuant to
paragraph (5) of this Section 5.5(a) or this paragraph (6) has been made, and (II)
the aggregate amount of any distributions to all holders of Common Stock made
exclusively in cash within the 12 months preceding the expiration of such tender
or exchange offer and in respect of which no adjustment pursuant to paragraph (5)
of this Section 5.5(a) or this paragraph (6) has been made, exceeds 15% of the
product of the Current Market Price per share of Common Stock as of the last time
(the “Expiration Time”) tenders could have been made pursuant to such tender or
exchange offer (as it may be amended) times the number of shares of Common Stock
outstanding (including any tendered shares) on the Expiration Time, then, and in
each such case, immediately prior to the opening of business on the day after the
date of the Expiration Time, the Settlement Rate or Early Settlement Rate, as
applicable, in effect, shall be adjusted so that the same shall equal the rate
determined by dividing the Settlement Rate or Early Settlement Rate, as
applicable, in effect immediately prior to the close of business on the date of
the Expiration Time by a fraction of which:

               (i) the numerator shall be equal to (A) the product of (1)
the Current Market Price per share of Common Stock on the date of
the Expiration Time and (2) the number of shares of Common Stock
outstanding (including any tendered shares) on the Expiration Time
less (B) the amount of cash plus the fair market value (determined
as aforesaid) of the aggregate consideration payable to
shareholders based on the transactions described in clauses (I)
and (II) above (assuming in the case of clause (I) the acceptance,
up to any maximum specified in the terms of the tender or exchange
offer, of Purchased Shares); and

               (ii) the denominator shall be equal to the product of (A) the
Current Market Price per share of Common Stock as of the
Expiration Time and (B) the number of shares of Common Stock
outstanding (including any tendered shares) as of the Expiration
Time less the number of all shares validly tendered and not
withdrawn as of the Expiration Time (the shares deemed so
accepted, up to any such maximum, being referred to as the
“Purchased Shares”).

               (7) The reclassification of Common Stock into securities including securities
other than Common Stock (other than

50

 

any reclassification upon a Reorganization
Event to which Section 5.5(b) applies) shall be deemed to involve:

               (i) a distribution of such securities other than Common Stock
to all holders of Common Stock (and the effective date of such
reclassification shall be deemed to be “the date fixed for the
determination of shareholders entitled to receive such
distribution” and the “date fixed for such determination” within
the meaning of paragraph (4) of this Section 5.5(a)); and

               (ii) a subdivision, split or combination, as the case may be,
of the number of shares of Common Stock outstanding immediately
prior to such reclassification into the number of shares of Common
Stock outstanding immediately thereafter (and the effective date
of such reclassification shall be deemed to be “the day upon which
such subdivision or split becomes effective” or “the day upon
which such combination becomes effective”, as the case may be, and
“the day upon which such
subdivision, split or combination becomes effective” within
the meaning of paragraph (3) of this Section 5.5(a)).

               (8) The “Current Market Price” per share of Common Stock on any day means the
average of the daily Closing Prices for the five consecutive Trading Days selected
by the Company commencing not more than 30 Trading Days before, and ending not
later than, the earlier of the day in question and the day before the “ex date”
with respect to the issuance or distribution requiring such computation. For
purposes of this paragraph, the term “ex date”, when used with respect to any
issuance or distribution, shall mean the first date on which the Common Stock
trades regular way on such exchange or in such market without the right to receive
such issuance or distribution.

               (9) All adjustments to the Settlement Rate or the Early Settlement Rate, as
applicable, shall be calculated to the nearest 1/10,000th of a share of Common
Stock (or if there is not a nearest 1/10,000th of a share, to the next lower
1/10,000th of a share). No adjustment in the Settlement Rate or the Early
Settlement Rate, as applicable, shall be required unless such adjustment would
require an increase or decrease of at least one percent thereof; provided,
however, that any adjustments which by reason of this subparagraph are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. If an adjustment is made to the Settlement Rate or the
Early Settlement Rate, as applicable, pursuant to paragraph (1), (2), (3), (4),
(5), (6), (7) or (10) of this Section 5.5(a), an adjustment shall also

51

 

be made to
the Applicable Closing Price solely to determine which of clauses (1), (2) or (3)
of the definition of Settlement Rate or the Early Settlement Rate, as applicable,
in Section 5.1 will apply on the Purchase Contract Settlement Date. Such
adjustment shall be made by multiplying the Applicable Closing Price by a fraction
of which the numerator shall be the Settlement Rate or the Early Settlement Rate,
as applicable, in effect immediately after such adjustment pursuant to paragraph
(1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.5(a) and the
denominator shall be the Settlement Rate or the Early Settlement Rate, as
applicable, in effect immediately before such adjustment; provided, however, that
if such adjustment to the Settlement Rate or the Early Settlement Rate, as
applicable, in effect, is required to be made pursuant to the occurrence of any of
the events contemplated by paragraph (1), (2), (3), (4), (5), (7) or (10) of this
Section 5.5(a) during the period taken into consideration for determining the
Applicable Closing Price, appropriate and customary adjustments shall be made to
the Settlement Rate or the Early Settlement Rate, as applicable.

               (10) The Company may make such increases in the Settlement Rate or the Early
Settlement Rate, as applicable, in addition to those required by this Section
5.5(a), as it
considers to be advisable in order to avoid or diminish any income tax to any
holders of shares of Common Stock resulting from any dividend or distribution of
stock or issuance of rights, options or warrants to purchase or subscribe for
stock or from any event treated as such for income tax purposes or for any other
reason.

               (b) Adjustment for Consolidation, Merger or Other Reorganization Event.

                    In the event of:

               (i) any consolidation or merger of the Company with or into another Person
(other than a merger or consolidation in which the Company is the continuing
corporation and in which the shares of Common Stock outstanding immediately prior
to the merger or consolidation are not exchanged for cash, securities or other
property of the Company or another corporation);

               (ii) any sale, transfer, lease or conveyance to another Person of the
property of the Company as an entirety or substantially as an entirety;

               (iii) any statutory exchange of securities of the Company with another Person
(other than in connection with a merger or acquisition); or

52

 

               (iv) any liquidation, dissolution or winding up of the Company other than as
a result of or after the occurrence of a Termination Event (any such event, a
“Reorganization Event”),

the Settlement Rate or Early Settlement Rate, as applicable, in effect, will be adjusted to provide
that each Holder of Units will receive on the Purchase Contract Settlement Date with respect to
each Purchase Contract forming a part thereof, the kind and amount of securities, cash and other
property receivable upon such Reorganization Event (without any interest thereon, and without any
right to dividends or distribution thereon which have a record date that is prior to the Purchase
Contract Settlement Date) by a Holder of the number of shares of Common Stock issuable on account
of each Purchase Contract if the Purchase Contract Settlement Date had occurred immediately prior
to such Reorganization Event, assuming such Holder of Common Stock is not a Person with which the
Company consolidated or into which the Company merged or which merged into the Company or to which
such sale or transfer was made, as the case may be (any such Person, a “Constituent Person”), or an
Affiliate of a Constituent Person to the extent such Reorganization Event provides for different
treatment of Common Stock held by Affiliates of the Company and non-Affiliates and such Holder
failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and
other property receivable upon such Reorganization Event (provided that if the kind or amount of
securities, cash and other property receivable upon such Reorganization Event is not the
same for each share of Common Stock held immediately prior to such Reorganization Event by other
than a Constituent Person or an Affiliate thereof and in respect of which such rights of election
shall not have been exercised (“non-electing share”), then for the purpose of this Section the kind
and amount of securities, cash and other property receivable upon such Reorganization Event by each
non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality
of the non-electing shares).

               In the event of such a Reorganization Event, the Person formed by such consolidation, merger
or exchange or the Person which acquires the assets of the Company or, in the event of a
liquidation, dissolution or winding up of the Company, the Company or a liquidating trust created
in connection therewith, shall execute and deliver to the Purchase Contract Agent an agreement
supplemental hereto providing that the Holders of each Outstanding Unit shall have the rights
provided by this Section 5.5(b). Such supplemental agreement shall provide for adjustments which,
for events subsequent to the effective date of such supplemental agreement, shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Section. The above
provisions of this Section shall similarly apply to successive Reorganization Events.

         (c) All calculations and determinations pursuant to this Section 5.5 shall be made by the
Company or its agent and the Purchase Contract Agent shall have no responsibility with respect
thereto.

53

 

Section 5.6 Notice of Adjustments and Certain Other Events.

               (a) Whenever the Settlement Rate or Early Settlement Rate, as applicable, and the Applicable
Closing Price are adjusted as herein provided, the Company shall:

               (i) forthwith compute the adjusted Settlement Rate or Early Settlement Rate,
as applicable and Applicable Closing Price in accordance with Section 5.5 and
prepare and transmit to the Purchase Contract Agent an Officer’s Certificate
setting forth the Settlement Rate or Early Settlement Rate, as applicable and the
Applicable Closing Price, the method of calculation thereof in reasonable detail,
and the facts requiring such adjustment and upon which such adjustment is based;
and

               (ii) within 10 Business Days following the occurrence of an event that
requires an adjustment to the Settlement Rate or Early Settlement Rate, as
applicable and the Applicable Closing Price pursuant to Section 5.5 (or if the
Company is not aware of such occurrence, as soon as practicable after becoming so
aware), provide a written notice to the Holders of the Units of the occurrence of
such event and a statement in reasonable detail setting forth the method by which
the
adjustment to the Settlement Rate then or Early Settlement Rate, as
applicable and the Applicable Closing Price was determined and setting forth the
adjusted Settlement Rate or Early Settlement Rate, as applicable and Applicable
Closing Price.

               (b) The Purchase Contract Agent shall not at any time be under any duty or responsibility to
any Holder of Units to determine whether any facts exist which may require any adjustment of the
Settlement Rate or Early Settlement Rate, as applicable or the Applicable Closing Price, or with
respect to the nature or extent or calculation of any such adjustment when made, or with respect to
the method employed in making the same. The Purchase Contract Agent shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any
securities or property, which may at the time be issued or delivered with respect to any Purchase
Contract; and the Purchase Contract Agent makes no representation with respect thereto. The
Purchase Contract Agent shall not be responsible for any failure of the Company to issue, transfer
or deliver any shares of Common Stock pursuant to a Purchase Contract or to comply with any of the
duties, responsibilities or covenants of the Company contained in this Article.

Section 5.7 Termination Event; Notice.

          The Purchase Contracts and all obligations and rights of the Company and the Holders
thereunder, including, without limitation, the rights of the Holders to receive, and the
obligations of the Company to pay, Purchase Contract Adjustment Payments and the rights and
obligations of Holders to purchase shares of Common Stock, shall immediately and automatically
terminate, without the necessity of any notice or action by

54

 

any Holder, the Purchase Contract Agent
or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall
have occurred. Upon and after the occurrence of a Termination Event, the Units shall thereafter
represent the right to receive the Debt Securities or Treasury Portfolio Interest forming a part of
such Units in the case of Corporate Units, or Treasury Securities in the case of Treasury Units, in
accordance with the provisions of Section 5.4 of the Pledge Agreement. Upon the occurrence of a
Termination Event, the Company shall promptly, but in no event later than two Business Days
thereafter, give written notice to the Purchase Contract Agent and the Collateral Agent and shall
cause written notice thereof to be given to the Holders, at their addresses as they appear in the
Register.

Section 5.8 Cash Settlement.

               (a) (i) Unless a Holder has effected an Early Settlement pursuant to Section 5.9 or a Merger
Early Settlement pursuant to Section 5.10, a Termination Event shall have occurred pursuant to
Section 5.7 or a Successful Remarketing shall have occurred, Holders of Corporate Units may settle
their Purchase
Contracts in cash by delivering to the Purchase Contract Agent a notice in substantially the
form of Exhibit F hereto regarding its intention to pay in cash (“Cash Settlement”) the Purchase
Price for the shares of Common Stock to be purchased pursuant to the related Purchase Contract;
provided that such notice must be given by 11:00 a.m. (New York City time) on the sixth Business
Day immediately preceding the Purchase Contract Settlement Date.

               (ii) A Holder of a Corporate Unit who has so notified the Purchase Contract
Agent of its intention to make a Cash Settlement in accordance with paragraph (a)
(i) above shall pay the Purchase Price to the Securities Intermediary for deposit

book-entry transfer or other appropriate procedures, in accordance with written
instructions provided by the Holder thereof, transfer such Debt Securities or such

interest payment thereon, in the name of the Purchase Contract Agent or its
nominee in trust for the benefit of such Holder until the expiration of the time
period specified in the abandoned property laws of the relevant State) and, in

subject to and upon compliance with the provisions of this Section 5.9, at the option of the Holder
thereof, Purchase Contracts relating to Units may be settled early (“Early Settlement”) on or prior
to the Election Date. In order to exercise the right to effect Early Settlement with respect to any

               (1) the product of (A) the Stated Amount times (B) the number of Purchase
Contracts with respect to which the Holder has elected to effect Early Settlement;
plus

               (2) if such delivery is made with respect to any Purchase Contracts during
the period from the close of business on any Record Date next preceding any
Payment Date to the opening of business on such Payment Date, an amount equal to
the Purchase Contract

58

 

Adjustment Payments payable on such Payment Date with
respect to such Purchase Contracts.

               Except as provided in the immediately preceding sentence and subject to the last paragraph of
Section 5.2, no payment shall be made upon Early Settlement of any Purchase Contract on account of
any Purchase Contract Adjustment Payments accrued on such Purchase Contract or on account of any
dividends on the Common Stock issued upon such Early Settlement. If the foregoing requirements are
first satisfied with respect to Purchase Contracts relating to any Units at or prior to 5:00 p.m.
(New York City time), on a Business Day, such day shall be the “Early Settlement Date” with respect
to such Units and if such requirements are first satisfied after 5:00 p.m. (New York City time), on

Contract Agent shall pay to the Company such Early Settlement Amount, the receipt of which payment
the Company shall confirm in writing. The Purchase Contract Agent shall then, in accordance with

to effect an Early Settlement, which notice shall set forth the number of such Purchase Contracts
as to which such Holder has elected to effect Early Settlement, (B) the Purchase Contract Agent has
received from such Holder, and paid to the Company as confirmed in writing by the Company, the
related Early Settlement Amount and (C) all conditions to such Early Settlement have been

adjustment in the same manner and at the same time as the Settlement Rate is adjusted pursuant to
Section 5.5, on account of each Purchase Contract as to which Early Settlement is effected (the
“Early Settlement Rate”).

               (c) No later than the third Business Day after the applicable Early Settlement Date, the
Company shall cause:

               (1) the shares of Common Stock issuable upon Early Settlement of the related
Purchase Contracts to be issued and delivered pursuant to Section 5.4, together
with payment in lieu of any fraction of a share, as provided in Section 5.12; and

               (2) the related Debt Securities, in the case of Corporate Units, or the
related Treasury Securities, in the case of Treasury Units, to be released from
the Pledge by the Collateral Agent and transferred, in each case, to the Purchase
Contract Agent for delivery to the Holder thereof or its designee.

59

 

               (d) Upon Early Settlement of any Purchase Contracts, and subject to receipt by the Common
Stock Transfer Agent of shares of Common Stock from the Company and receipt by the Purchase
Contract Agent of the related Debt Securities, or Treasury Securities, as the case may be, from the
Securities Intermediary, as applicable, the Common Stock Transfer Agent shall, in accordance with
the instructions provided by the Holder thereof on the applicable form of Election to Settle Early
on the reverse of the Certificate evidencing the related Units as forwarded by the Purchase
Contract Agent to the Common Stock Transfer Agent, deliver to such Holder a certificate or
certificates for the full number of shares of Common Stock issuable upon such Early Settlement of
the related Purchase Contract, pursuant to Section 5.4 and the Purchase Contract Agent shall
transfer to such Holder the related Debt Securities or Treasury Securities, as the case may be,
forming a part of such Units.

               (e) In the event that Early Settlement is effected with respect to Purchase Contracts relating
to less than all the Units evidenced by a Certificate, upon such Early Settlement the Company shall
execute and the Purchase Contract Agent shall
execute on behalf of the Holder, authenticate and deliver to the Holder thereof, at the
expense of the Company, a Certificate evidencing the Units as to which Early Settlement was not
effected.

               (f) Notwithstanding anything to the contrary contained herein, Holders may make effect Early
Settlement of Treasury Units only in integral multiples of 20 Treasury Units.

Section 5.10 Early Settlement Upon Merger.

               (a) In the event of a merger or consolidation of the Company (which for purposes of this
Section 5.10 includes any successor company pursuant to a Cash Merger (as defined below)) in which
the Common Stock outstanding immediately prior to such merger or consolidation is exchanged for
consideration consisting of at least 30% cash or cash equivalents (any such event a “Cash Merger”

Settlement right.

               (b) To exercise a Merger Early Settlement right, a Holder must (i) deliver to the Purchase
Contract Agent at the Corporate Trust Office at least three Business Days before the Merger
Settlement Date, at 5:00 p.m. (New York City time), the Certificate(s) evidencing the Units with

               (c) On the Merger Early Settlement Date, the Company shall cause to be delivered (i) the net
cash, securities and other property to be received by such exercising Holder, equal to the
Settlement Rate as adjusted pursuant to Section 5.5, in respect of the number of Purchase Contracts

each case, to the Purchase Contract Agent for delivery to the Holder thereof or its designee. In
the event a Merger Early Settlement right shall be exercised by a Holder in accordance with the

Section 5.11 Optional Remarketing.

          Pursuant to the Indenture and the Remarketing Agreement, holders of Separated Debt Securities
may elect to have such Separated Debt Security remarketed if such holder, on or prior to 5:00 p.m.
(New York City time) on the Election Date, delivers (a) to the Trustee and the Collateral Agent a
notice of that election, substantially in the form of Exhibit
___ of the Indenture Officer’s

principal amount of Debt Securities to be remarketed, and (b) such Separated Debt Securities, by
book-entry transfer or other appropriate procedures, to the Collateral Agent for Remarketing, in
each case, pursuant to the Indenture. Once the holder of such Separated Debt Securities delivers
such notice and Separated Debt Securities as specified in the preceding sentence, such election may
not be withdrawn and may not be conditioned upon the level at which the Reset Rate is established
in the Remarketing; provided, however, that if such a holder delivers only such a notice but not
the Separated Debt Securities subject to the notice, then none of such holder’s Separated Debt
Securities shall be included in the Remarketing.

Section 5.12 No Fractional Shares.

          No fractional shares or scrip representing fractional shares of Common Stock shall be issued
or delivered upon settlement on the Purchase Contract Settlement Date or upon Early Settlement or
Merger Early Settlement of any Purchase Contracts. If Certificates evidencing more than one
Purchase Contract shall be surrendered for settlement at one time by the same Holder, the number of
full shares of Common Stock

62

 

which shall be delivered upon settlement shall be computed on the basis
of the aggregate number of Purchase Contracts evidenced by the Certificates so surrendered. Instead
of any fractional share of Common Stock which would otherwise be deliverable upon settlement of any
Purchase Contracts on the Purchase Contract Settlement Date or upon Early Settlement or Merger
Early Settlement, the Company, through the Purchase Contract Agent, shall make a cash payment in
respect of such fractional interest in an amount equal to the value of such fractional shares times
the Applicable Closing Price. The Company shall provide the Purchase Contract Agent from time to
time with sufficient funds to permit the Purchase Contract Agent to make all cash payments required
by this Section 5.12 in a timely manner. Promptly after the calculation of the
Applicable Closing Price, the Company shall give the Purchase Contract Agent notice thereof.
All calculations and determinations of the Applicable Closing Price shall be made by the Company or
its agent and the Purchase Contract Agent shall have no responsibility with respect thereto.

Section 5.13 Charges and Taxes.

          The Company will pay all stock transfer and similar taxes attributable to the initial issuance
and delivery of the shares of Common Stock pursuant to the Purchase Contracts; provided, however,

of any exchange of or substitution for a Certificate evidencing a Unit or any issuance of a share
of Common Stock in a name other than that of the registered Holder of a Certificate surrendered in
respect of the Units evidenced thereby, other than in the name of the Purchase Contract Agent, as
custodian for such Holder, and the Company shall not be required to issue or deliver such share
certificates or Certificates unless the Person or Persons requesting the transfer or issuance
thereof shall have paid to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Agreement; and the Company expressly waives (to the extent
that it may lawfully do so) all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the Purchase Contract Agent or
the Holders, but will suffer and permit the execution of every such power as though no such law had

               (e) If the Purchase Contract Agent shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Purchase Contract Agent for any cause, the Company, by a
Board Resolution, shall promptly appoint a successor Purchase Contract Agent and shall comply with
the applicable requirements of Section 7.10. If no successor Purchase Contract Agent shall have
been so appointed by the Company and accepted appointment in the manner required by Section 7.10,
any Holder who has been a bona fide Holder of a Unit for at least six months may, on behalf of
itself and all others similarly situated, petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Purchase Contract Agent.

               (f) The Company shall give, or shall cause such successor Purchase Contract Agent to give,

and such successor Purchase Contract Agent, without any further act, deed or conveyance, shall
become vested with all the rights, powers, agencies and duties of the retiring Purchase

71

 

Contract
Agent; but, on the request of the Company or the successor Purchase Contract Agent, such retiring
Purchase Contract Agent shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Purchase Contract Agent all the rights, powers and trusts of the

the corporate trust business of the Purchase Contract Agent, shall be the successor of the Purchase
Contract Agent hereunder, provided such Person shall be otherwise eligible under this Article,
without the execution or filing of any paper or any further act on the part of any of the parties
hereto. In case any Certificates shall have been authenticated and executed on behalf of the
Holders, but not delivered, by the Purchase Contract Agent then in office, any successor to such
Purchase Contract Agent may adopt such authentication and execution and deliver the
Certificates so authenticated and executed with the same effect as if such successor Purchase
Contract Agent had itself authenticated and executed such Units.

Section 7.12 Preservation of Information; Communications to Holders.

               (a) The Purchase Contract Agent shall preserve, in as current a form as is reasonably

Purchase Contract Agent, and furnish to the Purchase Contract Agent reasonable proof that each such
applicant has owned a Unit for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to communicate with other
Holders with respect to their rights under this Agreement or under the Units and is by a copy of
the form of proxy or other communication which such applicants propose to transmit, then the
Purchase Contract Agent shall mail to all the Holders of Units copies of the form of proxy or other
communication which is specified in such request, with reasonable promptness after a

72

 

tender to the
Purchase Contract Agent of the materials to be mailed and of payment, or provision for the payment,

Section 7.13 No Obligations of Purchase Contract Agent.

          Except to the extent otherwise expressly provided in this Agreement, the Purchase Contract
Agent assumes no obligations and shall not be subject to any liability under this Agreement, the

thereunder. The Company agrees, and each Holder of a Certificate, by his acceptance thereof, shall
be deemed to have agreed, that the Purchase Contract Agent’s execution of the Certificates on
behalf of the Holders shall be solely as agent and attorney-in-fact for the Holders, and that the
Purchase Contract Agent shall have no obligation to perform such Purchase Contracts on behalf of
the Holders, except to the extent expressly provided in Article Five hereof. Anything contained in
this Agreement to the contrary notwithstanding, in no event shall the Purchase Contract Agent or
its officers, employees or agents be liable for indirect, special, punitive, or consequential loss

reasonable written direction received from the Company with respect to the execution or
certification of any required documentation and the application of such requirements to particular
payments or Holders or in other particular circumstances, and may for purposes of this Agreement
conclusively rely on any such direction in accordance with the provisions of Section 7.1(a)(2)
hereof.

          (c) The Purchase Contract Agent shall maintain all appropriate records documenting compliance
with such requirements, and shall make such records available, on written request, to the Company

(FORM OF REVERSE OF CORPORATE UNIT CERTIFICATE)

          1. Purchase Contract Agreement; Purchase Contracts.

          Each Purchase Contract evidenced hereby is being issued under and governed by a Purchase
Contract Agreement, dated as of [DATE] (as may be amended, modified or supplemented from time to
time pursuant to the terms thereof, the “Purchase Contract
Agreement”), between the Company and [       ], as Purchase Contract Agent (including its successors thereunder, the “Purchase Contract Agent”),
to which Purchase Contract Agreement and amended, modified or supplemental agreements thereto
reference is hereby made for a description of the respective rights, limitations of rights,
obligations, duties and immunities thereunder of the Purchase Contract Agent, the Company, and the
Holders and of the terms upon which the Corporate Unit Certificates are, and are to be, executed
and delivered. The terms of this Corporate Unit Certificate include those stated herein and in the
Purchase Contract Agreement. To the extent permitted by applicable law, in the event of an
inconsistency between this Corporate Unit Certificate and the Purchase Contract Agreement, the
terms of the Purchase Contract Agreement shall control. Capitalized terms used but not defined
herein have the meanings ascribed thereto in the Purchase Contract Agreement.

          Each Purchase Contract evidenced hereby obligates the Holder of this Corporate Unit
Certificate to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a
price equal to the Stated Amount (the “Purchase Price”), a number of shares of Common Stock equal
to the Settlement Rate then in effect unless on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event, an Early Settlement or a Merger Early Settlement
with respect to the Units of which such Purchase Contract is a part. The “Settlement Rate” is equal
to:

	 	(1)  	if the Applicable Closing Price (as defined
below) per share is equal to or greater than $___ (the “Threshold
Appreciation Price”), ___ shares of Common Stock per Purchase
Contract;
	 
	 	(2)  	if the Applicable Closing Price per share
is less than the Threshold Appreciation Price but greater than
$___ (the “Reference Price”), the number of shares of Common Stock
determined by dividing the Stated Amount by the Applicable Closing
Price; and
	 
	 	(3)  	if the Applicable Closing Price per share
is less than or equal to the Reference Price, ___ shares of Common
Stock per Purchase Contract,

in each case subject to adjustment as provided in the Purchase Contract Agreement.

          No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as
provided in the Purchase Contract Agreement.

A-5

 

          In accordance with the terms of the Purchase Contract Agreement, the Holder of this Corporate
Unit Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to
each Purchase Contract evidenced hereby by (i) effecting a Cash Settlement, an Early Settlement or
Merger Early Settlement or (ii) application of payments received in respect of the Pledged Treasury
Portfolio Interest acquired from the proceeds of a Remarketing of the related Pledged Debt
Securities relating to the Corporate Units represented by this Corporate Unit Certificate. As
provided in the Purchase Contract Agreement, upon the occurrence of a Failed Remarketing, the
Collateral Agent shall exercise, for the benefit of the Company, its rights as a secured creditor
with respect to the Pledged Debt Securities related to this Corporate Unit Certificate and, subject
to applicable law, may (i) retain such Pledged Debt Securities in full satisfaction of the Holders’
obligations under the Purchase Contracts or (ii) sell such Pledged Debt Securities in one or more
public or private sales, the proceeds, if any, of such sale to constitute full satisfaction of the
Holders’ obligations under the Purchase Contracts. With respect to such Pledged Debt Securities
which are the subject of a Failed Remarketing, any accrued and unpaid interest payments on such
Pledged Debt Securities will become payable by the Company to the Holder of this Corporate Unit
Certificate in the manner provided for in the Purchase Contract Agreement.

          The Company shall not be obligated to issue any shares of Common Stock in respect of a
Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received
payment of the aggregate purchase price for the shares of Common Stock to be purchased thereunder
in the manner set forth in the Purchase Contract Agreement which payment, in the case of a Failed
Remarketing shall occur by the resale of Pledged Debt Securities or foreclosure on and retention of
such Pledged Debt Securities pursuant to the Purchase Contract Agreement and the Pledge Agreement.

          2. Termination Event; Early Settlement; Merger Early Settlement.

          The Purchase Contracts and all obligations and rights of the Company and the Holders
thereunder, including, without limitation, the rights of the Holders to receive, and the obligation
of the Company to pay, Purchase Contract Adjustment Payments, shall immediately and automatically
terminate, without the necessity of any notice or action by any Holder, the Purchase Contract Agent
or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall
have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no
event later than two Business Days thereafter give written notice to the Purchase Contract Agent,
the Collateral Agent and the Holders, at their addresses as they appear in the Corporate Units
Register. Upon the occurrence of a Termination Event, the Collateral Agent shall release the Debt
Securities or Pledged Treasury Portfolio Interest, as the case may be, from the Pledge in
accordance with the provisions of the Pledge Agreement. A Corporate Unit shall thereafter represent
the right to receive the Debt Security forming a part of such Corporate Unit in accordance with the
terms of the Purchase Contract Agreement and the Pledge Agreement.

A-6

 

          Subject to and upon compliance with the provisions of the Purchase Contract Agreement, at the
option of the Holder thereof, Purchase Contracts relating to Units may be settled early (“Early
Settlement”) as provided in the Purchase Contract Agreement. In order to exercise the right to
effect Early Settlement with respect to any Purchase Contracts evidenced by this Corporate Unit
Certificate, the Holder of this Corporate Unit Certificate shall deliver this Corporate Unit
Certificate to the Purchase Contract Agent at the Corporate Trust Office duly endorsed for transfer
to the Company or in blank with the form of Election to Settle Early set forth below duly completed
and accompanied by payment in the form of immediately available funds payable to the order of the
Company in an amount (the “Early Settlement Amount”) equal to:

	 	(1)  	the product of (A) the Stated Amount times
(B) the number of Purchase Contracts with respect to which the Holder
has elected to effect Early Settlement, plus
	 
	 	(2)  	if such delivery is made with respect to
any Purchase Contracts during the period from the close of business
on any Record Date for any Payment Date to the opening of business on
such Payment Date, an amount equal to the Purchase Contract
Adjustment Payments payable on such Payment Date with respect to such
Purchase Contracts.

          Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Pledged Debt
Securities relating to such Units shall be released from the Pledge as provided in the Pledge
Agreement and the Holder shall be entitled to receive a number of shares of Common Stock on account
of each Purchase Contract forming part of a Corporate Unit as to which Early Settlement is effected
equal to the Early Settlement Rate. The Early Settlement Rate shall
initially be equal to ___ shares of Common Stock per Purchase Contract and shall be adjusted in the same manner and at the
same time as the Settlement Rate is adjusted as provided in the Purchase Contract Agreement.

          3. Creation of Treasury Units; Recreation of Corporate Units.

          A holder of a Corporate Unit may substitute for the Pledged Debt Securities securing its
obligation under the related Purchase Contract Treasury Securities in an aggregate principal amount
at maturity equal to the aggregate principal amount of the Pledged Debt Securities in accordance
with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after such
Collateral Substitution, the Units for which such Pledged Treasury Securities secures the Holder’s
obligation under the Purchase Contract shall be referred to as “Treasury Units.” A Holder may make
such Collateral Substitution only in integral multiples of 20 Corporate Units for 20 Treasury
Units. Such Collateral Substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, this Corporate Unit Certificate shall
not represent more than ___ Corporate Units, or if in the form of a Global Certificate, such
other maximum amount as shall at the time be prescribed by the applicable Depositary. All such
adjustments to the equivalent aggregate principal

A-7

 

amount of this Corporate Unit Certificate if a Global Certificate shall be duly recorded by
placing an appropriate notation on the Schedule as may be attached hereto.

          A Holder of Treasury Units may recreate Corporate Units by delivering to the Securities
Intermediary Debt Securities with an aggregate principal amount equal to the aggregate principal
amount at maturity of the Pledged Treasury Securities in exchange for the release of such Pledged
Treasury Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement. Holders may recreate Corporate Units only in integral multiples of 20 Corporate Units.

          4. Registered Form; Denomination; Registration, Transfer and Exchange.

          The Corporate Unit Certificates are issuable only in registered form and only in denominations
of a single Corporate Unit and any integral multiple thereof. The transfer of any Corporate Unit
Certificate will be registered and Corporate Unit Certificates may be exchanged as provided in the
Purchase Contract Agreement. The Corporate Units Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents permitted by the Purchase
Contract Agreement. No service charge shall be required for any such registration of transfer or
exchange, but the Company and the Purchase Contract Agent may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith. A Holder who elects
to substitute a Treasury Security for Debt Securities, thereby creating Treasury Units, shall be
responsible for any fees or expenses payable in connection therewith. Except as provided in the
Purchase Contract Agreement, for so long as the Purchase Contract relating to any Corporate Units
remains in effect, such Corporate Units shall not be separable into their constituent parts, and
the rights and obligations of the Holder of such Corporate Unit in respect of the Debt Security or
Treasury Portfolio Interest, as the case may be, and Purchase Contract constituting such Corporate
Units may be transferred and exchanged only as Corporate Units.

          Upon registration of transfer of this Corporate Unit Certificate, the transferee shall be
bound (without the necessity of any other action on the part of such transferee, except as may be
required by the Purchase Contract Agent pursuant to the Purchase Contract Agreement), under the
terms of the Purchase Contract Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contracts evidenced by this
Corporate Unit Certificate. The Company covenants and agrees, and the Holder, by its acceptance
hereof, likewise covenants and agrees, to be bound by the provisions of this paragraph.

          The Company, the Purchase Contract Agent and its Affiliates and any agent of the Company or
the Purchase Contract Agent may treat the Person in whose name this Corporate Unit Certificate is
registered as the owner of the Corporate Units evidenced hereby for the purpose of receiving
payments of interest payable quarterly on the Debt Securities or Treasury Portfolio Return, as the
case may be, receiving Purchase Contract Adjustment Payments, performance of the Purchase Contracts
and for all other purposes whatsoever, whether or not any payments in respect thereof be overdue
and

A-8

 

notwithstanding any notice to the contrary, and neither the Company, the Purchase Contract
Agent nor any such agent shall be affected by notice to the contrary.

          5. Place and Method of Payment.

          The Company shall pay, on each Payment Date, the Purchase Contract Adjustment Payments payable
in respect of each Purchase Contract to the Person in whose name the Corporate Unit Certificate
evidencing such Purchase Contract is registered at the close of business on the Record Date for
such Payment Date. Purchase Contract Adjustment Payments will be payable at the office of the
Purchase Contract Agent in The City of New York or, at the option of the Company by wire transfer
or by check mailed to the address of the Person entitled thereto at such address as it appears on
the Corporate Units Register.

          6. Authorization of Purchase Contract Agent.

          The Holder of this Corporate Unit Certificate, by its acceptance hereof, authorizes the
Purchase Contract Agent to enter into and perform the related Purchase Contracts forming part of
the Corporate Units evidenced hereby on its behalf as its attorney-in-fact, expressly withholds any
consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its
trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code,
agrees to be bound by the terms and provisions thereof, covenants and agrees to perform its
obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract
Agreement, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract
Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and consents to the
Pledge of the Debt Securities or Treasury Portfolio Interest, as the case may be, relating to this
Corporate Unit Certificate pursuant to the Pledge Agreement. The Holder further covenants and
agrees that, to the extent and in the manner provided in the Purchase Contract Agreement and the
Pledge Agreement, but subject to the terms thereof, payments in respect of the aggregate principal
amount of the Pledged Debt Securities or Pledged Treasury Portfolio Interest, as the case may be,
shall be paid on the Purchase Contract Settlement Date by the Collateral Agent to the Company in
satisfaction of such Holder’s obligations under such Purchase Contract and such Holder shall
acquire no right, title or interest in such payments.

          7. Amendment.

          The provisions of the Purchase Contract Agreement and this Corporate Unit Certificate may be
amended only as provided in the Purchase Contract Agreement.

          8. Voting Rights.

          The Purchase Contracts shall not, prior to the settlement thereof, entitle the Holder to any
of the rights of a holder of shares of Common Stock. Upon settlement of the Purchase Contracts, the
Holder will be entitled to all of the rights of a holder of shares of Common Stock, including,
without limitation, the right to vote and receive dividends and other payments and to consent and
receive notice as a shareholder in

A-9

 

respect of the meetings of shareholders and for the election of directors of the Company and
for all other matters, and all other rights whatsoever as a shareholder of the Company. Under the
terms of the Pledge Agreement, the Purchase Contract Agent will be entitled to exercise the voting
and any other consensual rights pertaining to the Pledged Debt Securities upon behalf of and upon
receipt of instructions from the beneficial owners of such Pledged Debt Securities. Upon receipt of
notice of any meeting at which holders of Debt Securities are entitled to vote or upon the
solicitation of consents, waivers or proxies of holders of Debt Securities, the Purchase Contract
Agent shall, as soon as practicable thereafter, mail to the Corporate Unit Holders a notice:

	 	(1)  	containing such information as is contained
in the notice or solicitation;
	 
	 	(2)  	stating that each Corporate Unit Holder on
the record date set by the Purchase Contract Agent therefor (which,
to the extent possible, shall be the same date as the record date for
determining the holders of Debt Securities entitled to vote) shall be
entitled to instruct the Purchase Contract Agent as to the exercise
of the voting rights pertaining to the Debt Securities constituting a
part of such Holder’s Corporate Units; and
	 
	 	(3)  	stating the manner in which such
instructions may be given.

Upon the written request of the Corporate Unit Holders on such record date, the Purchase Contract
Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the
instructions set forth in such requests, the maximum aggregate principal amount of Debt Securities
as to which any particular voting instructions are received. In the absence of specific
instructions from the Holder of a Corporate Unit, the Purchase Contract Agent shall abstain from
voting the Debt Securities evidenced by such Corporate Units.

          9. Severability.

          If any provision in this Corporate Unit and the Debt Securities is invalid or unenforceable in
any jurisdiction, then, to the fullest extent permitted by law, (i) the other provisions of this
Corporate Unit shall remain in full force and effect in such jurisdiction and shall be liberally
construed in order to carry out the intentions of the parties hereto as nearly as may be possible
and (ii) the invalidity or unenforceability of any provision of this Corporate Unit in any
jurisdiction shall not in any way affect the validity or enforceability of such provision in any
other jurisdiction.

          10. Governing Law.

          THIS CORPORATE UNIT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE
STATE OF NEW YORK.

A-10

 

          11. Jurisdiction; Venue.

          The Company hereby submits to the nonexclusive jurisdiction of the United States District
Court for the Southern District of New York for the purposes of all legal proceedings arising out
of or relating to the Indenture and the Debt Securities or the transactions contemplated hereby.
The Company hereto irrevocably waives, to the fullest extent permitted by applicable law, any
objection which it may now or hereafter have to the laying of the venue of any such proceeding
brought in such a court and any claim that any such proceeding brought in such a court has been
brought in an inconvenient forum.

          Pursuant to the Pledge Agreement, the Treasury Securities constituting part of each Treasury
Unit evidenced hereby have been pledged to the Collateral Agent, for the benefit of the Company, to
secure the obligations of the Holder under the Purchase Contract comprising a portion of such
Treasury Units.

          Each Purchase Contract evidenced hereby obligates the Holder of this Treasury Unit Certificate
to purchase, and the Company, to sell, on the Purchase Contract Settlement Date, at a price equal
to $50 in cash (the “Stated Amount”), a number of shares of Common Stock equal to the Settlement
Rate then in effect, unless on or prior to the Purchase Contract Settlement Date there shall have
occurred a Termination Event or an Early Settlement or Merger Early Settlement with respect to the
Treasury Units of which such Purchase Contract is a part, all as provided in the Purchase Contract
Agreement and more fully described on the reverse hereof. The purchase price (the “Purchase Price”)
for the shares of Common Stock purchased pursuant to each Purchase Contract evidenced hereby, if
not paid earlier, shall be paid on the Purchase Contract Settlement Date by application of the
proceeds from the Treasury Securities at maturity pledged pursuant to the Pledge Agreement to
secure the obligations under such Purchase Contract of the Holder of the Treasury Units of which
such Purchase Contract is a part.

          The
Company shall pay on ___, ___,

a “Payment Date”), commencing [DATE], in respect of each Purchase Contract forming part of the
Treasury Units evidenced hereby, an amount (the “Purchase Contract Adjustment Payments”) equal to
(a) if a Reset Transaction has not occurred, ___% per annum of the Stated Amount or (b) following
the occurrence of a Reset Transaction, if at all, the Adjusted Purchase Contract Adjustment Payment
Rate related to such Reset Transaction until any such succeeding Reset Transaction shall occur, in
either case, computed on the basis of (i) for any full quarterly period, a 360-day year of twelve
30-day months, (ii) for any period shorter than a full quarterly period, a 30-day month and (iii)
for periods less than a month, the actual number of days elapsed per 30-day period). Such Purchase
Contract Adjustment Payments shall be payable to the Person in whose name this Treasury Unit
Certificate (or a Predecessor Treasury Unit Certificate) is registered at the close of business on
the Record Date for such Payment Date.

          Purchase Contract Adjustment Payments will be payable at the office of the Purchase Contract
Agent in The City of New York or, at the option of the Company, by wire transfer or by check mailed
to the address of the Person entitled thereto as such address appears on the Treasury or Units
Register.

          Reference is hereby made to the further provisions set forth on the reverse hereof, which
further provisions shall for all purposes have the same effect as if set forth at this place.

          Unless the certificate of authentication hereon has been executed by the Purchase Contract
Agent by manual signature, this Treasury Unit Certificate shall not be entitled to any benefit

(FORM OF REVERSE OF TREASURY UNIT CERTIFICATE)

          1. Purchase Contract Agreement; Purchase Contracts.

          Each Purchase Contract evidenced hereby is being issued under and governed by a Purchase
Contract Agreement, dated as of [DATE] (as may be amended, modified or supplemented from time to
time pursuant to the terms thereof, the “Purchase Contract Agreement”) between the Company and [       ],
as Purchase Contract Agent (including its successors thereunder, the “Purchase Contract Agent”), to
which the Purchase Contract Agreement and supplemental agreements thereto reference is hereby made
for a description of the respective rights, limitations of rights, obligations, duties and
immunities thereunder of the Purchase Contract Agent, the Company and the Holders and of the terms
upon which the Treasury Unit Certificates are, and are to be, executed and delivered. The terms of
this Treasury Unit Certificate include those stated herein and in the Purchase Contract Agreement.
To the extent permitted by applicable law, in the event of an inconsistency between this Treasury
Unit Certificate and the Purchase Contract Agreement, the terms of the Purchase Contract Agreement
shall control. Capitalized terms used but not defined herein have the meanings ascribed thereto in
the Purchase Contract Agreement.

          Each Purchase Contract evidenced hereby obligates the Holder of this Treasury Unit Certificate
to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to
the Stated Amount (the “Purchase Price”) a number of shares of Common Stock equal to the Settlement
Rate then in effect unless on or prior to the Purchase Contract Settlement Date, there shall have
occurred a Termination Event, an Early Settlement or a Merger Early Settlement with respect to the
Units of which such Purchase Contract is a part. The “Settlement Rate” is equal to:

	 	(1)  	if the Applicable Closing Price (as defined
below) per share is equal to or greater than $___ (the “Threshold
Appreciation Price”), ___ shares of Common Stock per Purchase
Contract;
	 
	 	(2)  	if the Applicable Closing Price per share
is less than the Threshold Appreciation Price but greater than
$___ (the “Reference Price”), the number of shares of Common Stock
determined by dividing the Stated Amount by the Applicable Closing
Price; and
	 
	 	(3)  	if the Applicable Closing Price per share
is less than or equal to the Reference Price, then ___ shares of
Common Stock per Purchase Contract;

          in each case subject to adjustment as provided in the Purchase Contract Agreement.

          No fractional shares of Common Stock will be issued upon settlement of Purchase Contracts, as
provided in the Purchase Contract Agreement.

B-4

 

          In accordance with the terms of the Purchase Contract Agreement, the Holder of this Treasury
Unit Certificate shall pay the Purchase Price for the shares of Common Stock purchased pursuant to
each Purchase Contract evidenced hereby by (i) effecting a Cash Settlement, an Early Settlement or
Merger Early Settlement or (ii) application of payments received in respect of the Pledged Treasury
Securities relating to the Treasury Units represented by this Treasury Unit Certificate.

          The Company shall not be obligated to issue any shares of Common Stock in respect of a
Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received
payment of the aggregate purchase price for the shares of Common Stock to be purchased thereunder
in the manner herein set forth in the Purchase Contract Agreement.

          2. Termination Event; Early Settlement; Merger Early Settlement.

          The Purchase Contracts and all obligations and rights of the Company and the Holders
thereunder, including, without limitation, the rights of the Holders to receive, and the obligation
of the Company to pay, Purchase Contract Adjustment Payments, shall immediately and automatically
terminate, without the necessity of any notice or action by any Holder, the Purchase Contract Agent
or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall
have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no
event later than two Business Days thereafter give written notice to the Purchase Contract Agent,
the Collateral Agent and the Holders, at their addresses as they appear in the Treasury Units
Register. Upon the occurrence of a Termination Event, the Collateral Agent shall release the
Treasury Securities from the Pledge in accordance with the provisions of the Pledge Agreement. A
Treasury Unit shall thereafter represent the right to receive the interest in the Treasury Security
forming a part of such Treasury Unit, in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement.

          Subject to and upon compliance with the provisions of the Purchase Contract Agreement, at the
option of the Holder thereof, Purchase Contracts relating to Units may be settled early (“Early
Settlement”) as provided in the Purchase Contract Agreement. In order to exercise the right to
effect Early Settlement with respect to any Purchase Contracts evidenced by this Treasury Unit the
Holder of this Treasury Unit Certificate shall deliver this Treasury Unit Certificate to the
Purchase Contract Agent at the Corporate Trust Office duly endorsed for transfer to the Company or
in blank with the form of Election to Settle Early set forth below duly completed and accompanied
by payment in the form of immediately available funds payable to the order of the Company in an
amount (the “Early Settlement Amount”) equal to:

	 	(1)  	the product of (A) the Stated Amount times
(B) the number of Purchase Contracts with respect to which the Holder
has elected to effect Early Settlement, plus
	 
	 	(2)  	if such delivery is made with respect to
any Purchase Contracts during the period from the close of business
on

B-5

 

	 	   	any Record Date for any Payment Date to the opening of business on
such Payment Date, an amount equal to the Purchase Contract
Adjustment Payments payable on such Payment Date with respect to
such Purchase Contracts.

Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Pledged Treasury
Securities relating to such Units shall be released from the Pledge as provided in the Pledge
Agreement and the Holder shall be entitled to receive a number of shares of Common Stock on account
of each Purchase Contract forming part of a Treasury Unit as to which Early Settlement is effected
equal to the Early Settlement Rate. The Early Settlement Rate shall initially be equal to ___ shares of Common Stock per Purchase Contract and shall be adjusted in the same manner and at the
same time as the Settlement Rate is adjusted as provided in the Purchase Contract Agreement.

          3. Recreation of Corporate Units.

          A Holder of Treasury Units may recreate Corporate Units by delivering to the Collateral Agent
Debt Securities with a principal amount equal to the aggregate principal amount of maturity of the
Pledged Treasury Securities in exchange for the release of such Pledged Treasury Securities in
accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and
after such Collateral Substitution, the Holder’s Units shall be referred to as a “Corporate Units.”
Such Collateral Substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, this Treasury Unit Certificate shall
not represent more than ___ Treasury Units, or if in the form of a Global Certificate, such
other maximum amount as shall at the time be prescribed by the applicable Depositary. All such
adjustments to the equivalent aggregate principal amount of this Treasury Unit Certificate if a
Global Certificate, shall be duly recorded, by placing an appropriate notation on the Schedule as
may be attached hereto. A Holder who elects to substitute Debt Securities for Treasury Securities,
thereby recreating Corporate Units, shall be responsible for any fees or expenses associated
therewith.

          4. Registered Form; Denominations; Registration, Transfer and Exchange.

          The Treasury Unit Certificates are issuable only in registered form and only in denominations
of a single Treasury Unit and any integral multiple thereof. The transfer of any Treasury Unit
Certificate will be registered and Treasury Unit Certificates may be exchanged as provided in the
Purchase Contract Agreement. The Treasury Units Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the Purchase Contract
Agreement. No service charge shall be required for any such registration of transfer or exchange,
but the Company and the Purchase Contract Agent may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith. A Holder who elects to
substitute Debt Securities for a Treasury Security, thereby creating Corporate Units, shall be
responsible for any fees or expenses payable in connection therewith. Except as provided in the
Purchase Contract Agreement, for so long as the

B-6

 

Purchase Contract relating to the Treasury Units remains in effect, such Treasury Units shall
not be separable into their constituent parts, and the rights and obligations of the Holder of such
Treasury Units in respect of the Treasury Security and the Purchase Contract constituting such
Treasury Units may be transferred and exchanged only as Treasury Units.

          Upon registration of transfer of this Treasury Unit Certificate, the transferee shall be bound
(without the necessity of any other action on the part of such transferee, except as may be
required by the Purchase Contract Agent pursuant to the Purchase Contract Agreement), under the
terms of the Purchase Contract Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contracts evidenced by this
Treasury Unit Certificate. The Company covenants and agrees, and the Holder, by its acceptance
hereof, likewise covenants and agrees, to be bound by the provisions of this paragraph. The
Company, the Purchase Contract Agent and its Affiliates and any agent of the Company or the
Purchase Contract Agent may treat the Person in whose name this Treasury Unit Certificate is
registered as the owner of the Treasury Units evidenced hereby for the purpose of receiving
payments of Purchase Contract Adjustment Payments, performance of the Purchase Contracts and for
all other purposes whatsoever, whether or not any payments in respect thereof be overdue and
notwithstanding any notice to the contrary, and neither the Company, the Purchase Contract Agent
nor any such agent shall be affected by notice to the contrary.]

          5. Place and Method of Payment.

          The Company shall pay, on each Payment Date, the Purchase Contract Adjustment Payments payable
in respect of each Purchase Contract to the Person in whose name the Treasury Unit Certificate
evidencing such Purchase Contract is registered at the close of business on the Record Date for
such Payment Date. Purchase Contract Adjustment Payments will be payable at the office of the
Purchase Contract Agent in The City of New York or, at the option of the Company, by wire transfer
or by check mailed to the address of the Person entitled thereto at such address as it appears on
the Treasury Units Register.

          6. Authorization of Purchase Contract Agent.

          The Holder of this Treasury Unit Certificate, by its acceptance hereof, authorizes the
Purchase Contract Agent to enter into and perform the related Purchase Contracts forming part of
the Treasury Units evidenced hereby on its behalf as its attorney-in-fact, expressly withholds any
consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its
trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code,
agrees to be bound by the terms and provisions thereof, covenants and agrees to perform its
obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract
Agreement, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract
Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and consents to the
Pledge of the Treasury Securities relating to this Treasury Unit Certificate pursuant to

B-7

 

the Pledge Agreement. The Holder further covenants and agrees, that, to the extent and in the
manner provided in the Purchase Contract Agreement and the Pledge Agreement, but subject to the
terms thereof, payments in respect of the aggregate principal amount of the Pledged Treasury
Securities at maturity shall be paid on the Purchase Contract Settlement Date by the Collateral
Agent to the Company in satisfaction of such Holder’s obligations under such Purchase Contract and
such Holder shall acquire no right, title or interest in such payments.

          7. Amendment.

          The provisions of the Purchase Contract Agreement and this Treasury Unit Certificate may be
amended only as provided in the Purchase Contract Agreement.

          8. Voting Rights.

          The Purchase Contracts shall not, prior to the settlement thereof, entitle the Holder to any
of the rights of a holder of shares of Common Stock. Upon settlement of the Purchase Contracts, the
Holder will be entitled to all of the rights of a holder of shares of Common Stock, including,
without limitation, the right to vote and receive dividends and other payments and to consent and
receive notice as a shareholder in respect of the meetings of shareholders and for the election of
directors of the Company and for all other matters, and all other rights whatsoever as a
shareholder of the Company.

          9. Severability.

          If any provision in this Treasury Unit is invalid or unenforceable in any jurisdiction, then,
to the fullest extent permitted by law, (i) the other provisions of this Treasury Unit shall remain
in full force and effect in such jurisdiction and shall be liberally construed in order to carry
out the intentions of the parties hereto as nearly as may be possible and (ii) the invalidity or
unenforceability of any provision of this Treasury Unit in any jurisdiction shall not in any way
affect the validity or enforceability of such provision in any other jurisdiction.

          10. Governing Law.

          THIS TREASURY UNIT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE
STATE OF NEW YORK.

          11. Jurisdiction; Venue.

          The Company hereby submits to the nonexclusive jurisdiction of the United States District
Court for the Southern District of New York for the purposes of all legal proceedings arising out
of or relating to the Indenture and the Debt Securities or the transactions contemplated hereby.
The Company hereto irrevocably waives, to the fullest extent permitted by applicable law, any
objection which it may now or hereafter have to

B-8

 

the laying of the venue of any such proceeding brought in such a court and any claim that any
such proceeding brought in such a court has been brought in an inconvenient forum.

          12. Co-Units of Purchase Contract Agreement.

          A copy of the Purchase Contract Agreement is available for inspection at the offices of the
Purchase Contract Agent at its address set forth in Section 1.5 of the Purchase Contract Agreement.
