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 7.01) conclusive in favor of the Stock 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 proved in any manner that the Stock Purchase Contract Agent deems sufficient.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Common SPACES shall bind every future Holder of the same Common SPACES and the Holder of every Certificate evidencing such Common SPACES issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Stock Purchase Contract Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Certificate.

(e) The Company may set any date as a record date for the purpose of determining the Holders of Outstanding Common SPACES 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 Common SPACES. If any record date is set pursuant to this paragraph, the Holders of the Outstanding Normal Common SPACES and the Outstanding Stripped Common SPACES, 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 Normal Common SPACES or the Stripped Common SPACES, 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 prior to or on the applicable Expiration Date by Holders of the requisite number of Outstanding Common SPACES 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 Common SPACES 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 Stock Purchase Contract Agent in writing and to each Holder of Common SPACES in the manner set forth in Section 1.06.

With respect to any record date set pursuant to this Section 1.04(e), 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 Stock Purchase Contract Agent in writing, and to each Holder of Common SPACES in the manner set forth in Section 1.06, prior to or on 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.

Any notice or communication is duly given if in writing and delivered in Person or mailed by first-class mail (registered or certified, return receipt requested), telecopier (with receipt confirmed) or overnight air courier guaranteeing next day delivery, to the others’ address; provided that notice shall be deemed given to the Stock Purchase Contract Agent only upon receipt thereof:

The Stock Purchase Contract Agent shall send to the Indenture Trustee at the telecopier number set forth above a copy of any notices in the form of Exhibits C, D, E or F it sends or receives.

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 Security 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 Stock 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 Stock Purchase Contract Agent shall constitute a sufficient notification for every purpose hereunder.

The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

All covenants and agreements in this Agreement by the Company and the Stock Purchase Contract Agent shall bind their respective successors and assigns, whether so expressed or not.

In case any provision in this Agreement or in the Common SPACES shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof and thereof shall not in any way be affected or impaired thereby.

Nothing contained in this Agreement or in the Common SPACES, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and, to the extent provided hereby, the Holders, any benefits or any legal or equitable right, remedy or claim under this Agreement. The Holders from time to time shall be beneficiaries of this Agreement and shall be bound by all of the terms and conditions hereof and of the Common SPACES evidenced by their Certificates by their acceptance of delivery of such Certificates.

This Agreement and the Common SPACES shall be governed by, and construed in accordance with, the laws of the State of New York.

In any case where any Payment Date shall not be a Business Day (notwithstanding any other provision of this Agreement or the Common SPACES), Contract Payments or other distributions shall not be paid on such date, but Contract Payments or such other distributions shall be paid on the next succeeding Business Day with the same force and effect as if made on such Payment Date, provided that if such Business Day is in the next succeeding calendar year, then payment of the Contract Payments or other distributions will be made on the Business Day immediately preceding such Business Day. No interest shall accrue or be payable by the Company or to any Holder for the period from and after any such Payment Date.

In any case where the Stock Purchase Date or any Early Settlement Date or Cash Merger Early Settlement Date shall not be a Business Day (notwithstanding any other provision of this Agreement or the Common SPACES), Stock Purchase Contracts shall not be performed and Early Settlement and Cash Merger Early Settlement shall not be effected on such date, but Stock Purchase Contracts shall be performed or Early Settlement or Cash Merger Early Settlement shall be effected, as applicable, on the next succeeding Business Day with the same force and effect as if made on such Stock Purchase Date, Early Settlement Date or Cash Merger Early Settlement Date, as applicable.

This Agreement may be executed in any number of counterparts by the parties hereto on separate counterparts, each of which, when so executed and delivered, shall be deemed an original, but all such counterparts shall together constitute one and the same instrument.

The Company may appoint a financial institution (which may be the Collateral Agent) to act as its agent in performing its obligations and in accepting and enforcing performance of the obligations of the Stock Purchase Contract Agent and the Holders, under this Agreement and the Stock Purchase Contracts, by giving notice of such appointment in the manner provided in Section 1.05 hereof. Any such appointment shall not relieve the Company in any way from its obligations hereunder.

No failure on the part of the Company, the Stock Purchase Contract Agent, the Collateral Agent, the Securities Intermediary or any of their respective agents to exercise, and no course of dealing with respect to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Company, the Collateral Agent, the Securities Intermediary or any of their respective agents of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

The Certificates (including the form of Stock Purchase Contract forming part of each Common SPACES evidenced thereby) shall be in substantially the form set forth in Exhibit A hereto (in the case of Certificates evidencing Normal Common SPACES) or Exhibit B hereto (in the case of Certificates evidencing Stripped Common SPACES), 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 Common SPACES are listed or any depositary therefor, or as may, consistently herewith, be determined by the officers of the Company executing such Certificates, as evidenced by their execution of the Certificates.

The definitive Certificates shall be produced in any manner as determined by the officers of the Company executing the Common SPACES evidenced by such Certificates, consistent with the provisions of this Agreement, as evidenced by their execution thereof.

Every Global Certificate authenticated, executed on behalf of the Holders and delivered hereunder shall bear a legend in substantially the following form:

THIS CERTIFICATE IS A GLOBAL CERTIFICATE WITHIN THE MEANING OF THE PURCHASE CONTRACT AGREEMENT HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF CEDE & CO., AS NOMINEE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (THE “DEPOSITARY”), THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY. THIS CERTIFICATE IS EXCHANGEABLE FOR CERTIFICATES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE STOCK PURCHASE CONTRACT AGREEMENT AND NO TRANSFER OF THIS CERTIFICATE (OTHER THAN A TRANSFER OF THIS CERTIFICATE AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REQUESTED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITARY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

Section 2.02 Form of Stock Purchase Contract Agent’s Certificate of Authentication.

The form of the Stock Purchase Contract Agent’s certificate of authentication of the Common SPACES shall be in substantially the form set forth on the form of the applicable Certificates.

The aggregate number of Common SPACES evidenced by Certificates authenticated, executed on behalf of the Holders and delivered hereunder is limited to 14,600,000 (or 16,000,000 if the over-allotment option granted to the Underwriters pursuant to the Underwriting Agreement is exercised in

full), except for Certificates authenticated, executed and delivered upon registration of transfer of, in exchange for, or in lieu of, other Certificates pursuant to Section 3.04, Section 3.05, Section 3.10, Section 3.13, Section 3.14 or Section 8.05.

The Certificates shall be issuable only in registered form and only in denominations of a single Normal Common SPACES or Stripped Common SPACES and any integral multiple thereof.

Each Normal Common SPACES Certificate shall evidence the number of Normal Common SPACES specified therein, with each such Normal Common SPACES representing (1) the ownership by the Holder thereof of a 1/40 undivided beneficial interest in a STACKS, subject to the Pledge of such STACKS by such Holder pursuant to the Pledge Agreement, and (2) the rights and obligations of the Holder thereof and the Company under one Stock Purchase Contract. The Stock Purchase Contract Agent is hereby authorized, as attorney-in-fact for, and on behalf of, the Holder of each Normal Common SPACES, to pledge, pursuant to the Pledge Agreement, the STACKS forming a part of such Normal Common SPACES, to the Collateral Agent for the benefit of the Company, and to grant to the Collateral Agent, for the benefit of the Company, a security interest in the right, title and interest of such Holder in such STACKS to secure the obligation of the Holder under each Stock Purchase Contract to purchase shares of Common Stock.

Upon the formation of a Stripped Common SPACES pursuant to Section 3.13, each Stripped Common SPACES Certificate shall evidence the number of Stripped Common SPACES specified therein, with each such Stripped Common SPACES representing (1) the ownership by the Holder thereof of a 1/40 undivided beneficial interest in a Treasury Security with a principal amount at maturity equal to $1,000, subject to the Pledge of such interest by such Holder pursuant to the Pledge Agreement, and (2) the rights and obligations of the Holder thereof and the Company under one Stock Purchase Contract. The Stock Purchase Contract Agent is hereby authorized, as attorney-in-fact for, and on behalf of, the Holder of each Stripped Common SPACES, to pledge, pursuant to the Pledge Agreement, such Holder’s interest in the Treasury Security forming a part of such Stripped Common SPACES to the Collateral Agent, for the benefit of the Company, and to grant to the Collateral Agent, for the benefit of the Company, a security interest in the right, title and interest of such Holder in such Treasury Security to secure the obligation of the Holder under each Stock Purchase Contract to purchase shares of Common Stock.

Prior to the purchase of shares of Common Stock under each Stock Purchase Contract, such Stock Purchase Contract shall not entitle the Holder of a Common SPACES 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 stockholder in respect of the meetings of stockholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as a stockholder of the Company.

Subject to the provisions of Section 3.13 and Section 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 Stock 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 Stock 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 of Directors, its Chief Executive Officer, its President, its Chief Financial Officer, its Treasurer or one of its Vice Presidents. The signature of any of these officers on the Certificates may be manual or facsimile.

Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates.

No Stock 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 Stock Purchase Contract Agent, as such Holder’s attorney-in-fact. Such signature by an authorized officer of the Stock Purchase Contract Agent shall be conclusive evidence that the Holder of such Certificate has entered into the Stock Purchase Contracts evidenced by such Certificate.

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 Stock 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.

Pending the preparation of definitive Certificates, the Company shall execute and deliver to the Stock Purchase Contract Agent, and the Stock Purchase Contract Agent shall authenticate, execute on behalf of the Holders, and deliver, in lieu of such definitive Certificates, temporary Certificates that 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 Normal Common SPACES or Stripped Common SPACES, as the case may be, are listed, or as may, 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 Stock Purchase Contract Agent, and the Stock 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 number of Common SPACES 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 Common SPACES evidenced thereby as definitive Certificates.

The Stock Purchase Contract Agent shall keep at the Corporate Trust Office a register (the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Stock

Purchase Contract Agent shall provide for the registration of Certificates and of transfers of Certificates (the Stock Purchase Contract Agent, in such capacity, the “Security Registrar”). The Security Registrar shall record separately the registration and transfer of the Certificates evidencing Normal Common SPACES and Stripped Common SPACES.

Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office, the Company shall execute and deliver to the Stock Purchase Contract Agent, and the Stock 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 number of Normal Common SPACES or Stripped Common SPACES, 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 Normal Common SPACES or Stripped Common SPACES, 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 Stock Purchase Contract Agent, and the Stock Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver the Certificates that 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 number of Normal Common SPACES or Stripped Common SPACES, as the case may be, and be entitled to the same benefits and subject to the same obligations under this Agreement as the Normal Common SPACES or Stripped Common SPACES, 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 exchange shall (if so required by the Stock Purchase Contract Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Stock 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 Stock 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 Section 3.04, Section 3.06 and Section 8.05 not involving any transfer.

Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Stock Purchase Contract Agent, and the Stock 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 earliest to occur of any Early Settlement Date with respect to such Certificate, any Cash Merger Early Settlement Date with respect to such Certificate, the Stock Purchase 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 Stock Purchase Contract Agent shall:

(i) if the Stock Purchase Date (including upon any Cash Settlement) or an Early Settlement Date or a Cash Merger Early Settlement Date with respect to such other Certificate has occurred, deliver the shares of Common Stock issuable in respect of the Stock Purchase Contracts forming a part of the Common SPACES evidenced by such other Certificate; or

(ii) if a Termination Event shall have occurred prior to the Stock Purchase Date, transfer the STACKS 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 Section 3.15 and Article V hereof.

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. The Company hereby designates DTC as the initial Depositary. Such Global Certificates shall initially be registered on the books and records of the Company in the name of Cede & Co., the 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 3.09. The Stock 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 3.09:

(ii) the Company shall be entitled to deal with the Depositary for all purposes of this Agreement (including, without limitation, making Contract Payments and receiving approvals, votes or consents hereunder) as the Holder of the Common SPACES and the sole holder of the Global Certificates and shall have no obligation to the Beneficial Owners; provided that any Beneficial Owner may directly enforce against the Company, without the involvement of the Depositary or any other Person, its right to receive definitive Certificates pursuant to Section 3.09;

(iii) to the extent that the provisions of this Section 3.06 conflict with any other provisions of this Agreement, the provisions of this Section 3.06 shall control; and

(iv) 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 or the Depositary Participants; provided that any Beneficial Owner may directly enforce against the Company, without the involvement of the Depositary or any other Person, its right to receive definitive Certificates pursuant to Section 3.09.

Transfers of securities evidenced by Global Certificates shall be made through the facilities of the Depositary, and any cancellation of, or increase or decrease in the number of, such securities (including the creation of Stripped Common SPACES and the recreation of Normal Common SPACES pursuant to Section 3.13 and Section 3.14 respectively) shall be accomplished by making appropriate annotations on the Schedule of Increases and Decreases for such Global Certificate.

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 Common SPACES registered in the name of the Depositary or the nominee of the Depositary, the Company or the Company’s agent shall, except as set forth herein, have no obligations to the Beneficial Owners.

If the Depositary elects to discontinue its services as securities depositary with respect to the Common SPACES, the Company may, in its sole discretion, appoint a successor Depositary with respect to the Common SPACES.

(i) the Depositary notifies the Company that it is unwilling or unable to continue its services as securities depositary with respect to the Common SPACES and no successor Depositary has been appointed pursuant to Section 3.08 within 90 days after such notice; or

(ii) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act when the Depositary is required to be so registered to act as the Depositary and so notifies the Company, and no successor Depositary has been appointed pursuant to Section 3.08 within 90 days after such notice; or

(iii) any event of default has occurred and is continuing under the STACKS or this Agreement; or

(iv) the Company determines in its sole discretion that the Global Certificates shall be exchangeable for definitive Certificates,

then (x) definitive Certificates shall be prepared by the Company with respect to such Common SPACES and delivered to the Stock Purchase Contract Agent and (y) upon surrender of the Global Certificates representing the Common SPACES 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 Stock Purchase Contract Agent shall not be liable for any delay in delivery of such instructions and may conclusively rely on and shall be authorized and protected in relying on, such instructions. Each definitive Certificate so delivered shall evidence Common SPACES of the same kind and tenor as the Global Certificate so surrendered in respect thereof.

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

If there shall be delivered to the Company and the Stock 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 the Stock Purchase Contract Agent that such Certificate has been acquired by a protected purchaser, the Company shall execute and deliver to the Stock Purchase Contract Agent, and the Stock 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 Normal Common SPACES or Stripped Common SPACES, 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 Stock Purchase Contract Agent, and the Stock 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 earliest of any Early Settlement Date with respect to such lost or mutilated Certificate, any Cash Merger Early Settlement Date with respect to such lost or mutilated Certificate, the Stock Purchase 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 Stock Purchase Contract Agent shall:

(i) if the Stock Purchase Date or Early Settlement Date or Cash Merger Early Settlement Date with respect to such lost, stolen, destroyed or mutilated Certificate has occurred, deliver the shares of Common Stock issuable in respect of the Stock Purchase Contracts forming a part of the Common SPACES evidenced by such Certificate; or

(ii) if a Cash Settlement with respect to such lost or mutilated Certificate or if a Termination Event shall have occurred prior to the Stock Purchase Date, transfer the STACKS 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 Section 3.15 and Article V hereof.

Upon the issuance of any new Certificate under this Section, the Company and the Stock 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 fees and expenses (including, without limitation, the fees and expenses of the Stock 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 Common SPACES evidenced thereby, whether or not the destroyed, lost or stolen Certificate (and the Common SPACES 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.

Prior to due presentment of a Certificate for registration of transfer, the Company and the Stock Purchase Contract Agent, and any agent of the Company or the Stock Purchase Contract Agent, may treat the Person in whose name such Certificate is registered as the owner of the Common SPACES evidenced thereby for purposes of (subject to any applicable record date) any payment or distribution on the STACKS, payment of Contract Payments and performance of the Stock Purchase Contracts and for all other purposes whatsoever in connection with such Common SPACES, whether or not such payment, distribution, or performance shall be overdue and notwithstanding any notice to the contrary, and neither the Company nor the Stock Purchase Contract Agent, nor any agent of the Company or the Stock 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 Stock Purchase Contract Agent or any agent of the Company or the Stock

Purchase Contract Agent from giving effect to any written certification, proxy or other authorization furnished by the Depositary (or its nominee), as a Holder, with respect to such Global Certificate, or impair, as between such Depositary and the related Beneficial Owner, the operation of customary practices governing the exercise of rights of the Depositary (or its nominee) as Holder of such Global Certificate. None of the Company, the Stock Purchase Contract Agent or any agent of the Company or the Stock Purchase Contract Agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Certificate or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

All Certificates surrendered for delivery of shares of Common Stock on or after the Stock Purchase Date or upon the transfer of STACKS or for delivery of STACKS or Treasury Securities, as the case may be, after the occurrence of a Termination Event or pursuant to a Cash Settlement, an Early Settlement or a Cash Merger Early Settlement, or upon the registration of transfer or exchange of a Common SPACES, or a Collateral Substitution or the recreation of Normal Common SPACES shall, if surrendered to any Person other than the Stock Purchase Contract Agent, be delivered to the Stock Purchase Contract Agent along with appropriate written instructions regarding the cancellation thereof and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Stock Purchase Contract Agent for cancellation any Certificates previously authenticated, executed and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Certificates so delivered shall, upon an Issuer Order, be promptly cancelled by the Stock 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 Stock Purchase Contract Agent shall be disposed of in accordance with its customary practices.

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 Stock Purchase Contract Agent cancelled or for cancellation.

Section 3.13 Creation of Stripped Common SPACES by Substitution of Treasury Securities.

Subject to the conditions set forth in this Agreement, a Holder may, at any time from and after the date of this Agreement and on or prior to 5:00 p.m. (New York City time) on the seventh Business Day immediately preceding the Applicable Remarketing Settlement Date, effect a Collateral Substitution and separate the Pledged STACKS from the related Stock Purchase Contracts in respect of all or a portion of such Holder’s Normal Common SPACES by substituting for such Pledged STACKS, Treasury Securities or portions thereof maturing on the Applicable Remarketing Settlement Date in an aggregate principal amount at maturity equal to the aggregate liquidation amount of such Pledged STACKS; provided that Holders may make Collateral Substitutions only in integral multiples of 40 Normal Common SPACES. To effect such substitution, the Holder must:

hereto, (i) stating that the Holder has deposited the relevant amount of Treasury Securities with the Securities Intermediary for credit to the Collateral Account and (ii) instructing the Stock Purchase Contract Agent to instruct the Collateral Agent to release the Pledged STACKS underlying such Normal Common SPACES, whereupon the Stock Purchase Contract Agent shall promptly provide an instruction to such effect to the Collateral Agent, substantially in the form of Exhibit A to the Pledge Agreement.

Upon receipt of the Treasury 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 will cause the Securities Intermediary to effect the release of such Pledged STACKS from the Pledge and the transfer of such STACKS to the Stock Purchase Contract Agent on behalf of the Holder free and clear of the Company’s security interest therein. Upon receipt of such STACKS, the Stock Purchase Contract Agent shall promptly:

(ii) transfer the STACKS to the Holder (such STACKS shall be tradeable as a separate security, independent of the resulting Stripped Common SPACES); and

(iii) authenticate, execute on behalf of such Holder and deliver Stripped Common SPACES in book-entry form, or if applicable, in the form of a Stripped Common SPACES Certificate executed by the Company in accordance with Section 3.03 evidencing the same number of Stock Purchase Contracts as were evidenced by the cancelled Normal Common SPACES.

Holders who elect to separate the STACKS from the related Stock Purchase Contracts and to substitute Treasury Securities for such STACKS shall be responsible for any fees or expenses (including, without limitation, fees and expenses payable to the Collateral Agent for its services as Collateral Agent) in respect of the substitution, and neither the Company nor the Stock Purchase Contract Agent shall 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 Normal Common SPACES or fails to deliver Normal Common SPACES Certificates to the Stock Purchase Contract Agent after depositing Treasury Securities with the Securities Intermediary, any distributions on the STACKS constituting a part of such Normal Common SPACES shall be held in the name of the Stock Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until such Normal Common SPACES are so transferred or the Normal Common SPACES Certificate is so delivered, as the case may be, or, such Holder provides evidence satisfactory to the Company and the Stock Purchase Contract Agent that such Normal Common SPACES Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Stock Purchase Contract Agent and the Company.

Except as described in Section 5.02 or in this Section 3.13 or in connection with a Cash Settlement, an Early Settlement, a Cash Merger Early Settlement or a Termination Event, for so long as the Stock Purchase Contract underlying a Normal Common SPACES remains in effect, such Normal Common SPACES shall not be separable into its constituent parts, and the rights and obligations of the Holder in respect of the STACKS and the Stock Purchase Contract comprising such Normal Common SPACES may be acquired, and may be transferred and exchanged, only as a Normal Common SPACES.

Subject to the conditions set forth in this Agreement, a Holder of Stripped Common SPACES may recreate Normal Common SPACES at any time on or prior to 5:00 p.m. (New York City time) on the seventh Business Day immediately preceding the Applicable Remarketing Settlement Date; provided that Holders of Stripped Common SPACES may only recreate Normal Common SPACES in integral multiples of 40 Stripped Common SPACES. To recreate Normal Common SPACES, the Holder must:

Upon receipt of the STACKS 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 will cause the Securities Intermediary to effect the release of the Pledged Treasury Securities having a corresponding aggregate principal amount at maturity from the Pledge and the transfer thereof to the Stock Purchase Contract Agent on behalf of the Holder free and clear of the Company’s security interest therein. Upon receipt of such Treasury Securities, the Stock Purchase Contract Agent shall promptly:

(iii) authenticate, execute on behalf of such Holder and deliver Normal Common SPACES in book-entry form or, if applicable, in the form of a Normal Common SPACES Certificate executed by the Company in accordance with Section 3.03 evidencing the same number of Stock Purchase Contracts as were evidenced by the cancelled Stripped Common SPACES.

Holders who elect to recreate Normal Common SPACES shall be responsible for any fees or expenses (including, without limitation, fees and expenses payable to the Collateral Agent for its services as Collateral Agent) in respect of the recreation, and neither the Company nor the Stock Purchase Contract Agent shall be responsible for any such fees or expenses.

Except as provided in Section 5.02 or in this Section 3.14 or in connection with a Cash Settlement, an Early Settlement, a Cash Merger Early Settlement or a Termination Event, for so long as the Stock Purchase Contract underlying a Stripped Common SPACES remains in effect, such Stripped Common SPACES shall not be separable into its constituent parts and the rights and obligations of the

Holder of such Stripped Common SPACES in respect of the 1/40 of a Treasury Security and the Stock Purchase Contract comprising such Stripped Common SPACES may be acquired, and may be transferred and exchanged, only as a Stripped Common SPACES.

Upon the occurrence of a Termination Event and the transfer to the Stock Purchase Contract Agent of the STACKS or the Treasury Securities, as the case may be, underlying the Normal Common SPACES and the Stripped Common SPACES, as the case may be, pursuant to the terms of the Pledge Agreement, the Stock Purchase Contract Agent shall request transfer instructions with respect to such STACKS or Treasury Securities, as the case may be, from each Holder by written request, substantially in the form of Exhibit D hereto, mailed to such Holder at its address as it appears in the Security Register.

Upon book-entry transfer of the Normal Common SPACES or the Stripped Common SPACES or delivery of a Normal Common SPACES Certificate or Stripped Common SPACES Certificate to the Stock Purchase Contract Agent with such transfer instructions, the Stock Purchase Contract Agent shall transfer the STACKS or Treasury Securities, as the case may be, underlying such Normal Common SPACES or Stripped Common SPACES, 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 Normal Common SPACES or Stripped Common SPACES fails to effect such transfer or delivery, the STACKS or Treasury Securities, as the case may be, underlying such Normal Common SPACES or Stripped Common SPACES, as the case may be, and any distributions thereon, shall be held in the name of the Stock Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until the earlier to occur of:

(i) the transfer of such Normal Common SPACES or Stripped Common SPACES or surrender of the Normal Common SPACES Certificate or Stripped Common SPACES Certificate or the receipt by the Company and the Stock Purchase Contract Agent from such Holder of satisfactory evidence that such Normal Common SPACES Certificate or Stripped Common SPACES Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Stock Purchase Contract Agent and the Company; and

(ii) the expiration of the time period specified in the abandoned property laws of the relevant State in which the Stock Purchase Contract Agent holds such property.

Each Holder of a Common SPACES, 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 Stock 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.

Any payment on any STACKS which is paid on any Payment Date shall, subject to receipt thereof by the Stock Purchase Contract Agent from the Company (in the case of a STACKS that is held in

the name of the Stock Purchase Contract Agent) or from the Collateral Agent as provided by the terms of the Pledge Agreement (in the case of a STACKS that is held in the name of the Collateral Agent), be paid by the Stock Purchase Contract Agent to the Person in whose name the Normal Common SPACES Certificate (or one or more Predecessor Normal Common SPACES Certificates) of which such STACKS forms a part is registered at the close of business on the Record Date for such Payment Date.

Each Normal Common SPACES Certificate evidencing STACKS delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of any other Normal Common SPACES Certificate shall carry the right to accrued and unpaid interest or distributions, and to accrue distributions, which were carried by the STACKS underlying such other Normal Common SPACES Certificate.

In the case of any Normal Common SPACES with respect to which (A) Cash Settlement of the underlying Stock Purchase Contract is properly effected pursuant to Section 5.02(b) or Section 5.02(e) hereof, (B) Early Settlement of the underlying Stock Purchase Contract is properly effected pursuant to Section 5.07 hereof, (C) Cash Merger Early Settlement of the underlying Stock Purchase Contract is properly effected pursuant to Section 5.04(b)(ii) hereof, (D) a Collateral Substitution is properly effected pursuant to Section 3.13, or (E) a Successful Remarketing occurs with respect to the STACKS that is part of such Normal Common SPACES, in each case on a date that is after any Record Date and prior to or on the next succeeding Payment Date, distributions on the STACKS underlying such Normal Common SPACES otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Cash Settlement, Early Settlement, Cash Merger Early Settlement, Collateral Substitution or Initial Remarketing, and such payment or distributions shall, subject to receipt thereof by the Stock Purchase Contract Agent, be payable to the Person in whose name the Normal Common SPACES Certificate (or one or more Predecessor Normal Common SPACES Certificates) was registered at the close of business on the Record Date.

Except as otherwise expressly provided in the immediately preceding paragraph, in the case of any Normal Common SPACES with respect to which Cash Settlement, Early Settlement or Cash Merger Early Settlement of the underlying Stock Purchase Contract is properly effected, or with respect to which a Collateral Substitution has been effected, payments on the related STACKS that would otherwise be payable or made after the Stock Purchase Date, Early Settlement Date, Cash Merger Early Settlement Date or the date of the Collateral Substitution, as the case may be, shall not be payable hereunder to the Holder of such Normal Common SPACES; provided, however, that to the extent that such Holder continues to hold Separate STACKS that formerly comprised a part of such Holder’s Normal Common SPACES, such Holder shall be entitled to receive distributions on such Separate STACKS.

Under the terms of the Pledge Agreement, the Stock Purchase Contract Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged STACKS, 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 STACKS are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of STACKS, the Stock Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage pre-paid, to the Holders of Normal Common SPACES a notice:

(ii) stating that each Holder on the record date set by the Stock Purchase Contract Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of STACKS, as the case may be, entitled to vote) shall be entitled to

instruct the Stock Purchase Contract Agent as to the exercise of the voting rights pertaining to such STACKS underlying their Normal Common SPACES; and

Upon the written request of the Holders of Normal Common SPACES on such record date received by the Stock Purchase Contract Agent at least six days prior to such meeting, the Stock 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 number of STACKS, as the case may be, as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of a Normal Common SPACES, the Stock Purchase Contract Agent shall abstain from voting the STACKS underlying such Normal Common SPACES. The Company hereby agrees, if applicable, to solicit Holders of Normal Common SPACES to timely instruct the Stock Purchase Contract Agent in order to enable the Stock Purchase Contract Agent to vote such STACKS.

The Holders of Normal Common SPACES and Stripped Common SPACES shall have no voting or other rights in respect of Common Stock.

(a) Each Stock Purchase Contract shall obligate the Holder of the related Common SPACES to purchase, and the Company to sell, on the Stock Purchase Date at a price equal to $25 (the “Purchase Price”), a number of newly issued or treasury shares of Common Stock (subject to Section 5.09) equal to the Settlement Rate (as defined below) unless an Early Settlement, a Cash Merger Early Settlement or a Termination Event with respect to the Common SPACES of which such Stock Purchase Contract is a part shall have occurred. The “Settlement Rate” is equal to:

(i) if the Adjusted Applicable Market Value (as defined below) is greater than or equal to $46.28 (the “Threshold Appreciation Price”), 0.5402 shares of Common Stock per Stock Purchase Contract (such number of shares, as adjusted from time to time pursuant to Section 5.04, the “Minimum Share Number”);

(ii) if the Adjusted Applicable Market Value is less than the Threshold Appreciation Price but greater than $37.32 (the “Reference Price”), the number of shares of Common Stock per Stock Purchase Contract equal to the Stated Amount divided by the Applicable Market Value; and

(iii) if the Adjusted Applicable Market Value is less than or equal to the Reference Price, 0.6699 shares of Common Stock per Stock Purchase Contract (such number of shares, as adjusted from time to time pursuant to Section 5.04, the “Maximum Share Number”).

The “Adjusted Applicable Market Value” means (i) prior to any adjustment pursuant to paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a), the Applicable Market Value, and (ii) at the time of and after any adjustment of each Fixed Settlement Rate pursuant to paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a), the Applicable Market Value multiplied by the Adjustment Factor.

The “Adjustment Factor” means a fraction the numerator of which shall be the Maximum Share Number immediately after such adjustment pursuant to paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a) and the denominator of which shall be the Maximum Share Number immediately prior to such adjustment; provided, however, that if such adjustment to each Fixed Settlement Rate is required to be made pursuant to the occurrence of any of the events contemplated by paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a) during the period taken into consideration for determining the Applicable Market Value, the 20 individual Closing Prices used to determine the Applicable Market Value shall be adjusted rather than the Applicable Market Value and the Applicable Market Value shall be determined by (A) multiplying the Closing Prices for Trading Days prior to such adjustment to each Fixed Settlement Rate by the Adjustment Factor in effect prior to such adjustment, (B) multiplying the Closing Prices for Trading Days following such adjustment by the Adjustment Factor reflecting such adjustment, and (C) dividing the sum of all such adjusted Closing Prices by 20.

The “Applicable Market Value” means the average of the Closing Price per share of Common Stock on each of the 20 consecutive Trading Days ending on the third Trading Day immediately preceding August 15, 2007.

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

(i) the closing sale price as of the close of the principal trading session (or, if no closing price is reported, the last reported sale price) per share on the New York Stock Exchange, Inc. (the “NYSE”) on such date; or

(ii) if the Common Stock is not listed for trading on the NYSE on any such date, the closing sale price (or, if no closing price is reported, the last reported sale price) per share as reported in the composite transactions for the principal United States national or regional securities exchange on which the Common Stock is so listed; or

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

(iv) if the Common Stock is not so reported by the Nasdaq National Market, Inc., the last quoted bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization; or

(v) if the bid price referred to in clause (iv) is not available, the market value of Common Stock on such date as determined by a nationally recognized independent investment banking firm retained by the Company for purposes of determining the Closing Price.

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 over-the-counter market that is the primary market for the trading of the Common Stock.

(b) Each Holder of a Normal Common SPACES or a Stripped Common SPACES, by its acceptance of such Common SPACES:

(i) irrevocably authorizes the Stock Purchase Contract Agent to enter into and perform the related Stock Purchase Contract on its behalf as its attorney-in-fact (including, without limitation, the execution of Certificates on behalf of such Holder);

(iii) covenants and agrees to perform its obligations under such Stock Purchase Contract for so long as such Holder remains a Holder of a Normal Common SPACES or a Stripped Common SPACES;

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

(vi) consents to, and agrees to be bound by, the Pledge of such Holder’s right, title and interest in and to the Collateral Account, including the STACKS and the Treasury Securities pursuant to the Pledge Agreement; and

(vii) for United States federal, state and local income and franchise tax purposes, agrees to (A) treat an acquisition of the Normal Common SPACES as an acquisition of the STACKS and Stock Purchase Contracts constituting the Normal Common SPACES and (B) treat itself as the owner of the applicable interest in the Collateral Account, including the STACKS and the Treasury Securities,

provided that upon a Termination Event, the rights of the Holder of such Common SPACES under the Stock Purchase Contract may be enforced without regard to any other rights or obligations.

(c) Each Holder of a Normal Common SPACES or a Stripped Common SPACES, by its acceptance thereof, further covenants and agrees that to the extent and in the manner provided in Section 5.02 hereof and the provisions of the Pledge Agreement, but subject to the terms thereof, Proceeds of the STACKS or the Treasury Securities, as applicable, on the Stock Purchase Date, shall be paid by the Collateral Agent to the Company in satisfaction of such Holder’s obligations under such Stock Purchase Contract and such Holder shall acquire no right, title or interest in such Proceeds.

(d) 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 Stock Purchase Contracts underlying such Certificate and the Pledge Agreement and the transferor shall be released from the obligations under this Agreement, the Stock Purchase Contracts underlying the Certificate 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.

(a) (i) The Company shall conduct a Remarketing of the STACKS in accordance with Article X of the Trust Agreement and the Remarketing Agreement.

(ii) With respect to any STACKS which constitute part of Normal Common SPACES which are subject to the Final Remarketing with respect to the August 15, 2008

Remarketing Settlement Date, the Collateral Agent for the benefit of the Company reserves all of its rights as a secured party with respect thereto and, subject to applicable law and Section 5.02(c) below, may, among other things, (A) retain such STACKS in full satisfaction of the Holders’ obligations under the Stock Purchase Contracts or (B) sell such STACKS in one or more public or private sales or otherwise.

(iii) Prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the applicable Remarketing Date, but no earlier than the Payment Date immediately preceding such date, Holders of Separate STACKS may elect to have their Separate STACKS remarketed under the Remarketing Agreement by delivering their Separate STACKS, along with a notice of such election, substantially in the form of Exhibit F to the Pledge Agreement, to the Custodial Agent. The Custodial Agent shall hold Separate STACKS in an account separate from the Collateral Account in which the Pledged STACKS (as defined in the Pledge Agreement) shall be held. Holders of Separate STACKS electing to have their Separate STACKS remarketed will also have the right to withdraw that election by written notice to the Custodial Agent, substantially in the form of Exhibit G to the Pledge Agreement, on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the applicable Remarketing Date, upon which notice the Custodial Agent shall return such Separate STACKS to such Holder. Promptly after 11:00 a.m. on the Business Day immediately preceding the applicable Remarketing Date, the Custodial Agent shall notify the Remarketing Agent of the aggregate liquidation amount of the Separate STACKS to be remarketed. After such time, such election shall become an irrevocable election to have such Separate STACKS remarketed in such Remarketing.

(iv) The Stock Purchase Contract Agent shall give Holders of Common SPACES, and the Company shall request that the Depositary or its nominee give Depositary Participants holding Common SPACES and Separate STACKS, notice of a Remarketing at least 21 Business Days prior to the related Remarketing Date. Such notice will set forth the information required to be set forth in the notice pursuant to Section 10.4(a) of the Trust Agreement.

(b) (i) Unless an Early Settlement or a Cash Merger Early Settlement has occurred prior to the Stock Purchase Date, each Holder of Normal Common SPACES shall have the right to satisfy such Holder’s obligations under the Stock Purchase Contract on the Stock Purchase Date in cash by notifying the Stock Purchase Contract Agent by use of a notice in substantially the form of Exhibit E hereto of its intention to pay in cash (“Cash Settlement”) on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Stock Purchase Date. Promptly following 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Stock Purchase Date, the Stock Purchase Contract Agent shall notify the Collateral Agent and the Trustee of the receipt of such notices from Holders intending to make a Cash Settlement.

(ii) A Holder of a Normal Common SPACES who has so notified the Stock Purchase Contract Agent of its intention to effect a Cash Settlement shall pay the Purchase Price to the Collateral Agent for deposit in the Collateral Account on or prior to 5:00 p.m. (New York City time) on the fourth Business Day immediately preceding the Stock Purchase Date, in lawful money of the United States by certified or cashiers’ check or wire transfer of immediately available funds payable to or upon the order of the Securities Intermediary. Any cash so received shall be paid to the Company on the Stock Purchase Date in settlement of the Stock Purchase Contracts in accordance with the terms of this Agreement and the Pledge Agreement.

(iii) If a Holder of a Normal Common SPACES does not notify the Stock Purchase Contract Agent of its intention to make a Cash Settlement in accordance with Section 5.02(b)(ii)

above, or does notify the Stock Purchase Contract Agent in accordance with Section 5.02(b)(i) above but fails to make such payment as required by Section 5.02(b)(ii) above, such Holder shall be deemed to have consented to the disposition of the Pledged STACKS pursuant to the next applicable Remarketing.

(iv) As soon as practicable after 5:00 p.m. (New York City time) on the fourth Business Day preceding the Stock Purchase Date, the Collateral Agent, based on cash payments received by the Collateral Agent pursuant to Section 5.02(b)(ii) hereof, shall promptly notify the Stock Purchase Contract Agent of the aggregate liquidation amount of STACKS to be tendered for purchase in the Remarketing in a notice pursuant to the terms of the Pledge Agreement.

(v) In the event of a Failed Remarketing, (A) the Stock Purchase Date shall be deferred for a quarterly period (except in the case of a Failed Remarketing with respect to the August 15, 2008 Remarketing Settlement Date, in which case the Stock Purchase Date shall occur on August 15, 2008), and (B) if the Holders of Common SPACES have delivered cash in order to effect Cash Settlement in accordance with Section 5.02(b)(ii) above, the Collateral Agent will promptly return the cash that it has received with respect to the Cash Settlement to the Stock Purchase Contract Agent for distribution to the applicable Holders of Normal Common SPACES.

(vi) In the event of a Successful Remarketing, if the Holders of Common SPACES have delivered cash in order to effect Cash Settlement, the Collateral Agent will cause the Securities Intermediary to effect the release of Pledged STACKS from the Pledge and the transfer of such STACKS to the Stock Purchase Contract Agent on behalf of the Holders free and clear of the Company’s security interest therein. Upon receipt of such STACKS, the Stock Purchase Contract Agent shall promptly transfer the STACKS to the Holders.

(c) The obligations of the Holders to pay the Purchase Price are non-recourse obligations and, except to the extent satisfied by Early Settlement, Cash Merger Early Settlement or Cash Settlement, are payable solely out of the proceeds of any Collateral pledged to secure the obligations of the Holders, and in no event will Holders be liable for any deficiency between the Proceeds of the disposition of Collateral and the Purchase Price.

(d) The Company shall not be obligated to issue any shares of Common Stock in respect of a Stock Purchase Contract or deliver any certificates thereof to the Holder of the related Common SPACES unless the Company shall have received payment for the Common Stock to be purchased thereunder in the manner herein set forth.

Unless a Termination Event, an Early Settlement or a Cash Merger Early Settlement shall have occurred, subject to Section 5.04(b)(ii), on the Stock Purchase Date upon receipt of the aggregate Purchase Price payable on all Outstanding Common SPACES, the Company shall issue and deposit with the Stock Purchase Contract Agent, for the benefit of the Holders of the Outstanding Common SPACES, one or more certificates representing newly issued or treasury shares of Common Stock registered in the name of the Stock 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 Stock Purchase Date, being hereinafter referred to as the “Stock Purchase Contract Settlement Fund”) to which the Holders are entitled hereunder.

Subject to the foregoing, upon surrender of a Certificate to the Stock Purchase Contract Agent on or after the Stock Purchase Date, Early Settlement Date or Cash Merger Early 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 forthwith in exchange therefor a certificate representing that number of newly issued or treasury whole shares of Common Stock which such Holder is entitled to receive pursuant to the provisions of this Article V (after taking into account all Common SPACES then held by such Holder), together with cash in lieu of fractional shares as provided in Section 5.09 and any dividends or distributions with respect to such shares constituting part of the Stock Purchase Contract Settlement Fund, but without any interest thereon, and the Certificate so surrendered shall forthwith be cancelled. Such shares shall be registered in the name of the Holder or the Holder’s designee as specified in the settlement instructions provided by the Holder to the Stock Purchase Contract Agent. If any shares of Common Stock issued in respect of a Stock Purchase Contract are to be registered to a Person other than the Person in whose name the Certificate evidencing such Stock Purchase Contract is registered (but excluding any Depositary or nominee thereof), 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 Stock Purchase Contract or has established to the satisfaction of the Company that such tax either has been paid or is not payable.

(i) In case the Company shall pay or make a dividend or other distribution on Common Stock in Common Stock, each Fixed Settlement Rate in effect at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by dividing such Fixed Settlement Rate by a fraction of which:

(A) 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

(B) 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 at the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (i), 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 agrees that it shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

(ii) In case the Company shall issue rights, warrants or options, other than pursuant to any dividend reinvestment plans or share purchase plans, to all holders of its Common Stock (not being available on an equivalent basis to Holders of the Common SPACES upon settlement of the Stock Purchase Contracts underlying such Common SPACES) entitling them, for a period expiring within 45 days after the record date for the determination of stockholders entitled to receive such rights, warrants or options, 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 of announcement of such issuance, each Fixed Settlement Rate in effect at the close of business on the date of such announcement shall be increased by dividing such Fixed Settlement Rate by a fraction of which:

(A) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date of such announcement plus the number of shares of Common Stock that 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

(B) the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date of such announcement 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 Business Day following the date of such announcement. The Company agrees that it shall notify the Stock Purchase Contract Agent if any issuance of such rights, warrants or options is cancelled or not completed following the announcement thereof and each Fixed Settlement Rate shall thereupon be readjusted to the Fixed Settlement Rate in effect immediately prior to the date of such announcement. For the purposes of this paragraph (ii), 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 agrees that it shall not issue any such rights, warrants or options in respect of shares of Common Stock held in the treasury of the Company.

(iii) In case outstanding shares of Common Stock shall be subdivided or split into a greater number of shares of Common Stock, each Fixed Settlement Rate in effect at the close of business on the day preceding 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 Common Stock, such Settlement Rate in effect at the close of business on the day preceding 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 at the opening of business on the day following the day upon which such subdivision, split or combination becomes effective.

(iv) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including shares of capital stock, securities, cash and property but excluding any rights, warrants or options referred to in paragraph (i) or (ii) of this Section 5.04(a), and any dividend or distribution paid exclusively in cash), each Fixed Settlement Rate in effect at the close of business on the date fixed for the determination of stockholders entitled to receive such distribution shall be adjusted by dividing such rate by a fraction of which:

(A) 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 the basis for which shall be generally 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

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

such adjustment to become effective at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. In any case in which this paragraph

(iv) is applicable, paragraph (ii) of this Section 5.04(a) shall not be applicable. In the event that such dividend or distribution is not so paid or made, each Fixed Settlement Rate shall again be adjusted to be the Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared.

(v) In case the Company or any of its subsidiaries shall, by dividend or otherwise, make distributions consisting exclusively of cash to all holders of Common Stock, excluding any cash dividend on the Common Stock to the extent that the aggregate cash dividend per share of Common Stock in any quarter does not exceed $0.21 (the “Dividend Threshold Amount”) (the Dividend Threshold Amount is subject to adjustment whenever the Fixed Settlement Rates are adjusted, which adjustment shall be the inverse of the adjustment made to the Fixed Settlement Rates, provided that no adjustment shall be made to the Dividend Threshold Amount for any adjustment made pursuant to this Section 5.04(a)(v)) then, in such case, each Fixed Settlement Rate in effect at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend shall be adjusted by dividing such rate by a fraction of which:

(A) the numerator shall be the Current Market Price on such date less the amount of cash so distributed applicable to one share of Common Stock in excess of the Dividend Threshold Amount; and

such adjustment to be effective at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or distribution; provided that if the portion of the cash so distributed applicable to one share of Common Stock in excess of the Dividend Threshold Amount is equal to or greater than the Current Market Price on such date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of a Common SPACES shall have the right to receive upon settlement of the Common SPACES such excess amount. In the event that such dividend or distribution is not so paid or made, each Fixed Settlement Rate shall again be adjusted to be the Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared.

(vi) In case a tender or exchange offer made by the Company or any subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, each Fixed Settlement Rate shall be increased so that the same shall equal the rate determined by dividing such Fixed Settlement Rate in effect immediately prior to the Expiration Time by a fraction,

(A) the numerator of which shall be equal to the product of (x) the Current Market Price of a share of Common Stock as of the Expiration Time and (y) the number of shares of Common Stock outstanding (including any shares accepted in terms of the tender or exchange offer, such shares being referred to as the “Purchased Shares”) at the Expiration Time less the fair market value (determined by the Board of Directors as aforesaid) of the aggregate consideration payable to stockholders for all Purchased Shares, and

(B) the denominator of which shall be the product of (x) the number of shares of Common Stock outstanding at the Expiration Time less any Purchased Shares and (y) the Current Market Price of a share of Common Stock at the Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, each Fixed Settlement Rate shall again be adjusted to be the Fixed Settlement Rate that would then be in effect if such tender or exchange offer had not been made.

(vii) The reclassification of Common Stock into securities including securities other than Common Stock (other than any reclassification upon a Reorganization Event to which Section 5.04(b) applies) shall be deemed to involve:

(A) 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 stockholders entitled to receive such distribution” and the “date fixed for such determination” within the meaning of paragraph (iv) of this Section); and

(B) 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 (iii) of this Section).

(viii) The “Current Market Price” per share of Common Stock on any date of determination means the average of the daily Closing Prices for the ten Trading Days ending on the earlier of such date of determination 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 Common Stock trades regular way on such exchange or in such market without the right to receive such issuance or distribution.

(ix) All adjustments to the Fixed Settlement Rate 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 adjustments in the Settlement Rate shall be required unless such adjustment would require an increase or decrease of at least one percent thereof; provided, however, that any adjustment which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment.

(x) The Company may, but shall not be required to, make such increases in the Fixed Settlement Rate, in addition to those required by this Section, as the Board of Directors 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 or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes or for any other reason. Any such adjustment to the Fixed Settlement Rate shall be proportionally made to both the Maximum Share Number and the Minimum Share Number.

(xi) If the Company hereafter adopts any stockholder rights plan, a Holder shall be entitled to receive upon settlement of its Stock Purchase Contracts, in addition to the shares of Common Stock issuable upon settlement, the related rights for the Common Stock, unless the rights under the future stockholder rights plan have separated from the Common Stock at the time of settlement, in which case each Fixed Settlement Rate shall be adjusted as provided in Section 5.04(a)(iv) on the date such rights separate from the Common Stock. Notwithstanding the foregoing, in lieu of any such adjustment to each Fixed Settlement Rate, the Company may, in its sole discretion, amend the future stockholders rights plan to provide that a Holder shall be entitled to receive upon settlement of its Stock Purchase Contracts, in addition to the shares of Common Stock issuable upon settlement, the related rights for the Common Stock that would have attached to such shares of Common Stock had the rights not separated from the Common Stock under such stockholders rights plan.

(A) 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);

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

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

(D) any liquidation, dissolution or termination of the Company other than as a result of or after the occurrence of a Termination Event (any event described in clauses (A), (B), (C) and (D), a “Reorganization Event”),

the Settlement Rate will be adjusted to provide that each Holder of Common SPACES will receive on the Stock Purchase Date with respect to each Stock Purchase Contract forming a part thereof for each share issuable pursuant to the Stock Purchase Contract, 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 Stock Purchase Date) by a Holder of the one share of Common Stock (the “Exchange Property”). The kind and amount of Exchange Property will be determined 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 its 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 5.04(b)(i) 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).

The actual amount of Exchange Property receivable upon settlement of each Stock Purchase Contract shall be (1) in the case of settlement on the Stock Purchase Date or pursuant to Section 5.04(b)(ii), a variable amount based upon the applicable Settlement Rate and the Applicable Market Value of the Exchange Property at such time and (2) in the case of any Early Settlement, determined in accordance with the procedures described under Section 5.07 using the Settlement Rate that results in the minimum amount of Exchange Property being delivered under such Stock Purchase Contract.

For purposes of this Section 5.04(b)(i) and Section 5.04(b)(ii), the term “Applicable Market Value” shall be deemed to refer to the “Applicable Market Value” of the Exchange Property, and such value shall be determined (A) with respect to any publicly traded securities that compose all or part of the Exchange Property, based on the Closing Price of such securities, (B) in the case of any cash that composes all or part of the Exchange Property, based on the amount of such cash and (C) in the case of any other property that composes all or part of the Exchange Property, based on the value of such property, as determined by a nationally recognized independent investment banking firm retained by the Company for this purpose; provided that prior to the separation of the Rights or any similar stockholder rights from the Common Stock, such Rights or similar stockholder rights shall be deemed to have no value. The term “Closing Price” shall be deemed to refer to the closing sale price, last quoted bid price or mid-point of the last bid and ask prices, as the case may be, of any publicly traded securities that comprise all or part of the Exchange Property. The term “Trading Day” shall be deemed to refer to any publicly traded securities that comprise all or part of the Exchange Property.

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 termination of the Company, the Company or a liquidating trust created in connection therewith, shall execute and deliver to the Stock Purchase Contract Agent an agreement supplemental hereto providing that each Holder of an Outstanding Common SPACES shall have the rights provided by this Section 5.04(b)(i). 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 5.04. The above provisions of this Section 5.04 shall similarly apply to successive Reorganization Events.

(ii) In the event of a consolidation or merger of the Company with or into another Person (other than a consolidation or merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock), in each case in which 30% or more of the total consideration paid to the Company’s stockholders consists of cash or cash equivalents (a “Cash Merger”), then a Holder of a Common SPACES may settle (“Cash Merger Early Settlement”) its Stock Purchase Contract, upon the conditions set forth below, at the Settlement Rate in effect immediately prior to the closing of the Cash Merger; provided that (A) the Cash Merger Early Settlement Date (as defined below) is no later than the fifth Business Day immediately preceding the Stock Purchase Date and (B) no Cash Merger Early Settlement will be permitted pursuant to this Section 5.04(b)(ii) unless, at the time such Cash Merger Early Settlement is effected, there is an effective Registration Statement with respect to any securities to be issued and delivered in connection with such Cash Merger Early Settlement, if such a Registration Statement is required (in the view of counsel, which need not be in the form of a written opinion, for the Company) under the Securities Act. If such a Registration Statement is so required, the Company covenants and agrees to use reasonable best efforts to (x) have in effect a Registration Statement covering any securities to be delivered in respect of the Stock

Purchase Contracts being settled and (y) provide a Prospectus in connection therewith, in each case in a form that may be used in connection with such Cash Merger Early Settlement.

Within five Business Days of the completion of a Cash Merger, the Company shall provide written notice to Holders of Common SPACES of such completion of a Cash Merger, which shall specify the deadline for submitting the notice to settle early in cash pursuant to this Section 5.04(b)(ii), the date on which such Cash Merger Early Settlement shall occur (which date shall be 10 days after the date of such written notice by the Company, but which shall in no event be later than the earlier of the 20th day after the date of such notice and the fifth Business Day immediately preceding the Stock Purchase Date) (the “Cash Merger Early Settlement Date”), the applicable Settlement Rate and the amount (per share of Common Stock) of cash, securities and other consideration receivable by the Holder upon settlement. In addition, if a Holder effects a Cash Merger Early Settlement of some or all of its Stock Purchase Contracts, such Holder shall be entitled to receive, on the Cash Merger Early Settlement Date, the aggregate amount of any accrued and unpaid Contract Payments since the immediately preceding Payment Date with respect to such Stock Purchase Contracts. The Company shall pay such amount as a credit against the amount otherwise payable by the Holders to effect such Cash Merger Early Settlement.

Normal Common SPACES Holders and Stripped Common SPACES Holders may only effect Cash Merger Early Settlement pursuant to this Section 5.04(b)(ii) in integral multiples of 40 Normal Common SPACES or Stripped Common SPACES, as the case may be. Other than the provisions relating to timing of notice and settlement, which shall be as set forth above, the provisions of Section 5.01(a) shall apply with respect to a Cash Merger Early Settlement pursuant to this Section 5.04(b)(ii).

In order to exercise the right to effect Cash Merger Early Settlement with respect to any Stock Purchase Contracts, the Holder of the Certificate evidencing Common SPACES shall deliver, no later than 5:00 p.m. (New York City time) on the third Business Day immediately preceding the Cash Merger Early Settlement Date, such Certificate to the Stock 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 on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds) in an amount equal to the product of (A) the Stated Amount times (B) the number of Stock Purchase Contracts with respect to which the Holder has elected to effect Cash Merger Early Settlement, less any credit in respect of Contract Payments as set forth above.

If a Holder properly effects an effective Cash Merger Early Settlement in accordance with the provisions of this Section 5.04(b)(ii), the Company will deliver (or will cause the Collateral Agent to deliver) to the Holder on the Cash Merger Early Settlement Date:

(A) the kind and amount of securities, cash and other property receivable upon such Cash Merger by a Holder of the number of shares of Common Stock issuable on account of each Stock Purchase Contract if the Stock Purchase Date had occurred immediately prior to such Cash Merger (based on the Settlement Rate in effect at such time), assuming such Holder of Common Stock is not a Constituent Person or an Affiliate of a Constituent Person to the extent such Cash Merger provides for different treatment of Common Stock held by Affiliates of the Company and non-affiliates and such Holder failed to exercise its rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such Cash Merger (provided that if the kind or amount of securities, cash and other property receivable upon such Cash Merger is not the same for each non-electing share, then for the purpose of this Section 5.04(b)(ii), the kind and amount of securities, cash and other property receivable upon such Cash Merger 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). For the avoidance of doubt, for the

purposes of determining the Adjusted Applicable Market Value (in connection with determining the appropriate Settlement Rate to be applied in the foregoing sentence), the date of the closing of the Cash Merger shall be deemed to be the Stock Purchase Date;

(B) the STACKS or Treasury Securities, as the case may be, related to the Stock Purchase Contracts with respect to which the Holder is effecting a Cash Merger Early Settlement; and

(c) All calculations and determinations pursuant to this Section 5.04 shall be made by the Company or its agent and the Stock Purchase Contract Agent shall have no responsibility with respect thereto.

(d) The Normal Common SPACES or the Stripped Common SPACES of the Holders who do not elect Cash Merger Early Settlement in accordance with the foregoing will continue to remain outstanding and be subject to settlement on the Stock Purchase Date in accordance with the terms hereof.

(a) Whenever the Fixed Settlement Rate is adjusted as provided under Section 5.04(a), or the Settlement Rate is adjusted under Section 5.04(b), the Company shall within 10 Business Days following the occurrence of an event that requires such adjustment (or if the Company is not aware of such occurrence, as soon as reasonably practicable after becoming so aware):

(i) compute the adjusted Fixed Settlement Rate or Settlement Rate, as the case may be, in accordance with Section 5.04 and prepare and transmit to the Stock Purchase Contract Agent an Officers’ Certificate setting forth the Fixed Settlement Rate or Settlement Rate, as the case may be, the method of calculation thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and

(ii) provide a written notice to the Holders of the Common SPACES of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Fixed Settlement Rate or Settlement Rate, as the case may be, was determined and setting forth the adjusted Fixed Settlement Rate or Settlement Rate, as the case may be.

(b) The Stock Purchase Contract Agent shall not at any time be under any duty or responsibility to any Holder of Common SPACES to determine whether any facts exist which may require any adjustment of the Fixed Settlement Rate or Settlement Rate, as the case may be, 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 Stock Purchase Contract Agent shall be fully authorized and protected in relying on any Officers’ Certificate delivered pursuant to Section 5.05(a)(i) and any adjustment contained therein and the Stock Purchase Contract Agent shall not be deemed to have knowledge of any adjustment unless and until it has received such certificate. The Stock 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 Stock Purchase Contract; and the Stock Purchase Contract Agent makes no representation with respect thereto. The Stock 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 Stock

Purchase Contract or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article V.

The Stock 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 any Contract Payments (including any accrued and unpaid Contract Payments), if the Company shall have such obligation, and the rights and obligations of Holders to purchase Common Stock, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Stock Purchase Contract Agent or the Company, if, prior to or on the Stock Purchase Date, a Termination Event shall have occurred.

Upon and after the occurrence of a Termination Event, the Common SPACES shall thereafter represent the right to receive the STACKS or the Treasury Securities, as the case may be, forming part of such Common SPACES, in accordance with the provisions of Section 5.04 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 Stock Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register.

(a) Subject to and upon compliance with the provisions of this Section 5.07, at the option of the Holder thereof, Stock Purchase Contracts underlying Common SPACES having an aggregated Stated Amount equal to $1,000 or an integral multiple thereof may be settled early (“Early Settlement”) at any time on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Stock Purchase Date; provided that no Early Settlement will be permitted pursuant to this Section 5.07 unless, at the time such Early Settlement is effected, there is an effective Registration Statement with respect to any securities to be issued and delivered in connection with such Early Settlement, if such a Registration Statement is required (in the view of counsel, which need not be in the form of a written opinion, for the Company) under the Securities Act. If such a Registration Statement is so required, the Company covenants and agrees to use commercially reasonable efforts to (i) have in effect a Registration Statement covering any securities to be delivered in respect of the Stock Purchase Contracts being settled and (ii) provide a Prospectus in connection therewith, in each case in a form that may be used in connection with such Early Settlement.

(b) In order to exercise the right to effect Early Settlement with respect to any Stock Purchase Contracts, the Holder of the Certificate evidencing Common SPACES shall deliver, at any time prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Stock Purchase Date, such Certificate to the Stock 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 on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds) in an amount (the “Early Settlement Amount”) equal to the sum of:

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

(ii) if such delivery is made with respect to any Stock 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 Contract Payments payable on such Payment Date with respect to such Stock Purchase Contracts.

Except as provided in the immediately preceding sentence, no payment shall be made upon Early Settlement of any Stock Purchase Contract on account of any Contract Payments accrued on such Stock 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 Stock Purchase Contracts underlying any Common SPACES on 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 Common SPACES and if such requirements are first satisfied after 5:00 p.m. (New York City time) on a Business Day or on a day that is not a Business Day, the “Early Settlement Date” with respect to such Common SPACES shall be the next succeeding Business Day.

Upon the receipt of such Certificate and Early Settlement Amount from the Holder, the Stock Purchase Contract Agent shall pay to the Company such Early Settlement Amount, the receipt of which payment the Company shall confirm in writing. The Stock Purchase Contract Agent shall then, in accordance with Section 5.6 of the Pledge Agreement, notify the Collateral Agent that (A) such Holder has elected to effect an Early Settlement, which notice shall set forth the number of such Stock Purchase Contracts as to which such Holder has elected to effect Early Settlement, (B) the Stock 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 satisfied.

Holders of Stripped Common SPACES may only effect Early Settlement pursuant to this Section 5.07 in integral multiples of 40 Stripped Common SPACES.

Upon Early Settlement of the Stock Purchase Contracts, the rights of the Holders to receive and the obligation of the Company to pay any Contract Payments (including any accrued and unpaid Contract Payments) with respect to such Stock Purchase Contracts shall immediately and automatically terminate.

(c) Upon Early Settlement of Stock Purchase Contracts by a Holder of the related Common SPACES, the Company shall issue, and the Holder shall be entitled to receive, 0.5402 newly issued or treasury shares of Common Stock, as adjusted in the same manner and the same time as the Settlement Rate is adjusted (the “Early Settlement Rate”).

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

(i) the shares of Common Stock issuable upon Early Settlement of Stock Purchase Contracts to be issued and delivered, together with payment in lieu of any fraction of a share, as provided in Section 5.09; and

(ii) the related Pledged STACKS, in the case of Normal Common SPACES, or the related Pledged Treasury Securities, in the case of Stripped Common SPACES, to be released from the Pledge by the Collateral Agent, free and clear of the Company’s security interest therein, and transferred, in each case, to the Stock Purchase Contract Agent for delivery to the Holder thereof or its designee.

(e) Upon Early Settlement of any Stock Purchase Contracts, and subject to receipt of shares of Common Stock from the Company and the STACKS or Treasury Securities, as the case may be, from the Securities Intermediary, as applicable, the Stock Purchase Contract 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 Common SPACES:

(i) transfer to the Holder the STACKS or Treasury Securities, as the case may be, forming a part of such Common SPACES,

(ii) deliver to the Holder a certificate or certificates for the full number of shares of Common Stock issuable upon such Early Settlement, together with payment in lieu of any fraction of a share, as provided in Section 5.09, and

(iii) if so required under the Securities Act, deliver a Prospectus for the shares of Common Stock issuable upon such Early Settlement as contemplated by (a).

(f) In the event that Early Settlement is effected with respect to Stock Purchase Contracts underlying less than all the Common SPACES evidenced by a Certificate, upon such Early Settlement the Company shall execute and the Stock 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 Common SPACES as to which Early Settlement was not effected.

(g) A Holder of a Common SPACES who effects Early Settlement may elect to have the STACKS no longer a part of a Normal Common SPACES remarketed in accordance with the provisions of Section 5.02.

No fractional shares or scrip representing fractional shares of Common Stock shall be issued or delivered upon settlement on the Stock Purchase Date, or upon Early Settlement or Cash Merger Early Settlement of any Stock Purchase Contracts. If Certificates evidencing more than one Stock Purchase Contract shall be surrendered for settlement at one time by the same Holder, the number of full shares of Common Stock that shall be delivered upon settlement shall be computed on the basis of the aggregate number of Stock Purchase Contracts evidenced by the Certificates so surrendered. Instead of any fractional share of Common Stock that would otherwise be deliverable upon settlement of any Stock Purchase Contracts on the Stock Purchase Date, or upon Early Settlement or Cash Merger Early Settlement, the Company, through the Stock Purchase Contract Agent, shall make a cash payment in respect of such fractional interest in an amount equal to the percentage of such fractional share times (i) the Applicable Market Value calculated as if the date of such settlement were the Stock Purchase Date, or (ii) if the Stock Purchase Date shall be deferred beyond August 15, 2007, the Closing Price of Common Stock on the Trading Day immediately preceding the Stock Purchase Date. The Company shall provide the Stock Purchase Contract Agent from time to time with sufficient funds to permit the Stock Purchase Contract Agent to make all cash payments required by this Section 5.09 in a timely manner.

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 Stock Purchase Contracts; provided, however, that the Company shall not be required to pay any such tax or taxes which may be payable in respect of any exchange of or substitution for a Certificate evidencing a Common SPACES 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 Common SPACES evidenced thereby, other than in the name of the Stock 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 or until 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.

(a) Subject to Section 5.11(d) and Section 5.12, the Company shall pay, on each Payment Date, the Contract Payments payable in respect of each Stock Purchase Contract to the Person in whose name a Certificate is registered at the close of business on the Record Date relating to such Payment Date. The Contract Payments will be payable at the office of the Stock Purchase Contract Agent in the Borough of Manhattan, New York City maintained for that purpose. If the book-entry system for the Common SPACES has been terminated, the Contract Payments will be payable, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or by wire transfer to the account designated by such Person by a prior written notice to the Stock Purchase Contract Agent. If any date on which Contract Payments are to be made is not a Business Day, then payment of the Contract Payments payable on such date will be made on the next succeeding day that is a Business Day (and without any interest in respect of such delay). Contract Payments payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. The Contract Payments will accrue from July 29, 2004.

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

(c) 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 Normal Common SPACES) any other Certificate shall carry the right to accrued and unpaid Contract Payments, which right was carried by the Stock Purchase Contracts underlying such other Certificates.

(d) In the case of any Common SPACES with respect to which Early Settlement or Cash Merger Early Settlement of the underlying Stock Purchase Contract is effected on a date that is after any Record Date and prior to or on the next succeeding Payment Date, Contract Payments otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Early Settlement or Cash Merger Early Settlement, and such Contract Payments shall be paid to the Person in whose name the Certificate evidencing such Common SPACES is registered at the close of business on such Record Date. Except as otherwise expressly provided in the immediately preceding sentence, and the right to receive accrued and unpaid Contract Payments as set forth in Section 5.04(b)(ii), in the case of any Common SPACES with respect to which Early Settlement or Cash Merger Early Settlement of the underlying Stock Purchase Contract is effected, Contract Payments that would otherwise be payable after the Early Settlement or Cash Merger Early Settlement Date with respect to such Stock Purchase Contract shall not be payable.

(e) The Company’s obligations with respect to Contract Payments, if any, will be subordinated and junior in right of payment to the Company’s obligations under any Senior Debt.

(f) In the event of (A) any insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment, composition or other similar proceeding relating to the Company, its creditors or its property, (B) any proceeding for the liquidation, dissolution or other winding up of the Company, voluntary or involuntary, whether or not involving insolvency or bankruptcy proceedings, (C) any assignment by the Company for the benefit of creditors, or (D) any other marshalling of the assets of the Company:

(i) all Senior Debt (including any interest thereon accruing after the commencement of any such proceedings) shall first be paid in full before any payment or distribution, whether in cash, securities or other property, shall be made to any Holder of Common SPACES;

(ii) any payment or distribution, whether in cash, securities or other property, which would otherwise (but for these subordination provisions) be payable or deliverable in respect of the Common SPACES shall be paid or delivered directly to the holders of Senior Debt in accordance with the priorities then existing among such holders until all Senior Debt (including any interest thereon accruing after the commencement of any such proceedings) shall have been paid in full;

(iii) after payment in full of all sums owing with respect to Senior Debt, the Holders of Common SPACES, together with the holders of any obligations of the Company ranking on a parity with the Common SPACES, shall be entitled to be paid from the remaining assets of the Company the amounts at the time due and owing on account of unpaid Contract Payments and interest thereon and such other obligations before any payment or other distribution, whether in cash, property or otherwise, shall be made on account of any capital stock or any obligations of the Company ranking junior to the Company’s obligations under the Stock Purchase Contracts and such other obligations; and

(iv) in the event that, notwithstanding the foregoing, any payment or distribution of any character or any security, whether in cash, securities or other property, shall be received by the Stock Purchase Contract Agent or any Holder of Common SPACES in contravention of any of the terms hereof such payment or distribution or security shall be received in trust for the benefit of, and shall be paid over or delivered and transferred to, the holders of the Senior Debt at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all such Senior Debt in full. In the event of the failure of the Stock Purchase Contract Agent or any Holder of Common SPACES to endorse or assign any such payment, distribution or security, each holder of Senior Debt is hereby irrevocably authorized to endorse or assign the same.

(g) For purposes of Section 5.11(e) through (q), the words “cash, property or securities” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other Person provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in Section 5.11(e) through (q) with respect to such Contract Payments on the Common SPACES to the payment of all Senior Debt which may at the time be outstanding; provided that (i) the indebtedness or guarantee of indebtedness, as the case may be, that constitutes Senior Debt is assumed by the Person, if any, resulting from any such reorganization or readjustment, and (ii) the rights of the holders of the Senior Debt are not, without the consent of each such holder adversely affected thereby, altered by such reorganization or readjustment;

(h) Any failure by the Company to make any payment on or perform any other obligation under Senior Debt, other than any indebtedness incurred by the Company or assumed or guaranteed, directly or indirectly, by the Company for money borrowed (or any deferral, renewal, extension or refunding thereof) or any indebtedness or obligation as to which the provisions of Section 5.11(e) through (q) shall have been waived by the Company in the instrument or instruments by which the Company incurred, assumed, guaranteed or otherwise created such indebtedness or obligation, shall not be deemed a default or event of default if (i) the Company shall be disputing its obligation to make such payment or perform such obligation and (ii) either (A) no final judgment relating to such dispute shall have been issued against the Company which is in full force and effect and is not subject to further review, including a judgment that has become final by reason of the expiration of the time within which a party may seek

further appeal or review, and (B) in the event a judgment that is subject to further review or appeal has been issued, the Company shall in good faith be prosecuting an appeal or other proceeding for review and a stay of execution shall have been obtained pending such appeal or review.

(i) Subject to the irrevocable payment in full of all Senior Debt, the Holders of the Common SPACES shall be subrogated (equally and ratably with the holders of all obligations of the Company which by their express terms are subordinated to Senior Debt of the Company to the same extent as payment of the Contract Payments in respect of the Stock Purchase Contracts underlying the Common SPACES is subordinated and which are entitled to like rights of subrogation) to the rights of the holders of Senior Debt to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Debt until all such Contract Payments owing on the Common SPACES shall be paid in full, and as between the Company, its creditors other than holders of such Senior Debt and the Holders, no such payment or distribution made to the holders of Senior Debt by virtue of Section 5.11(e) through (q) that otherwise would have been made to the Holders shall be deemed to be a payment by the Company on account of such Senior Debt, it being understood that the provisions of Section 5.11(e) through (q) are and are intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of Senior Debt, on the other hand.

(j) Nothing contained in Section 5.11(e) through (q) or elsewhere in this Agreement or in the Common SPACES is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Debt and the Holders, the obligation of the Company, which is absolute and unconditional, to pay to the Holders such Contract Payments on the Common SPACES as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of the Company other than the holders of Senior Debt, nor shall anything herein or therein prevent the Stock Purchase Contract Agent or any Holder from exercising all remedies otherwise permitted by applicable law upon default under this Agreement, subject to the rights, if any, under Section 5.11(e) through (q), of the holders of Senior Debt in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

(k) Upon payment or distribution of assets of the Company referred to in Section 5.11(e) through (q), the Stock Purchase Contract Agent and the Holders shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any such dissolution, winding up, liquidation or reorganization proceeding affecting the affairs of the Company is pending or upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or Stock Purchase Contract Agent or other person making any payment or distribution, delivered to the Stock Purchase Contract Agent or to the Holders, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Section 5.11(e) through (q).

(l) The Stock Purchase Contract Agent shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Debt (or a trustee or representative on behalf of such holder) to establish that such notice has been given by a holder of Senior Debt or a trustee or representative on behalf of any such holder or holders. In the event that the Stock Purchase Contract Agent determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to Section 5.11(e) through (q), the Stock Purchase Contract Agent may request such Person to furnish evidence to the reasonable satisfaction of the Stock Purchase Contract Agent as to the amount of Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under Section 5.11(e) through (q),

and, if such evidence is not furnished, the Stock Purchase Contract Agent may defer payment to such Person pending judicial determination as to the right of such Person to receive such payment.

(m) Nothing contained in Section 5.11(e) through (q) shall affect the obligations of the Company to make, or prevent the Company from making, payment of the Contract Payments, except as otherwise provided in this Section 5.11(e) through (q).

(n) Each Holder of Common SPACES, by its acceptance thereof, authorizes and directs the Stock Purchase Contract Agent on its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in Section 5.11(e) through (q) and appoints the Stock Purchase Contract Agent its attorney-in-fact, as the case may be, for any and all such purposes.

(o) The Company shall give prompt written notice to the Stock Purchase Contract Agent of any fact known to the Company that would prohibit the making of any payment of moneys to or by the Stock Purchase Contract Agent in respect of the Common SPACES pursuant to the provisions of this Section. Notwithstanding the provisions of Section 5.11(e) through (q) or any other provisions of this Agreement, the Stock Purchase Contract Agent shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of moneys to or by the Stock Purchase Contract Agent, or the taking of any other action by the Stock Purchase Contract Agent, unless and until the Stock Purchase Contract Agent shall have received written notice thereof mailed or delivered to the Stock Purchase Contract Agent at its Institutional Trust Services department from the Company, any Holder, or the holder or representative of any Senior Debt; provided that if at least two Business Days prior to the date upon which by the terms hereof any such moneys may become payable for any purpose, the Stock Purchase Contract Agent shall not have received with respect to such moneys the notice provided for in this Section, then, anything herein contained to the contrary notwithstanding, the Stock Purchase Contract Agent shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary that may be received by it within two Business Days prior to or on or after such date.

(p) The Stock Purchase Contract Agent in its individual capacity shall be entitled to all the rights set forth in this Section with respect to any Senior Debt at the time held by it, to the same extent as any other holder of Senior Debt and nothing in this Agreement shall deprive the Stock Purchase Contract Agent of any of its rights as such holder.

(q) No right of any present or future holder of any Senior Debt to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Agreement, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

(r) Nothing in this Section 5.11 shall apply to claims of, or payments to, the Stock Purchase Contract Agent under or pursuant to Section 7.07.

(s) With respect to the holders of Senior Debt, (i) the duties and obligations of the Stock Purchase Contract Agent shall be determined solely by the express provisions of this Agreement; (ii) the Stock Purchase Contract Agent shall not be liable to any such holders if it shall, acting in good faith, mistakenly pay over or distribute to the Holders or to the Company or any other Person cash, property or securities to which any holders of Senior Debt shall be entitled by virtue of this Section 5.11 or otherwise; (iii) no implied covenants or obligations shall be read into this Agreement against the Stock Purchase Contract Agent; and (iv) the Stock Purchase Contract Agent shall not be deemed to be a fiduciary as to such holders.

(a) The Company shall have the right, at any time prior to the Stock Purchase Date, to defer the payment of any or all of the Contract Payments otherwise payable on any Payment Date, but only if the Company shall give the Holders and the Stock Purchase Contract Agent written notice of its election to defer each such deferred Contract Payment (specifying the amount to be deferred) at least ten Business Days prior to the earlier of (i) the next succeeding Payment Date or (ii) the date the Company is required to give notice of the Record Date or Payment Date with respect to payment of such Contract Payments to the NYSE or other applicable self-regulatory organization or to Holders of the Common SPACES, but in any event not less than one Business Day prior to such Record Date. Any Contract Payments so deferred shall, to the extent permitted by law, accrue interest thereon at the rate of 6.50% per year (computed on the basis of a 360-day year of twelve 30-day months), compounding on each succeeding Payment Date, until paid in full (such deferred installments of Contract Payments, if any, together with the additional Contract Payments, if any, accrued thereon, being referred to herein as the “Deferred Contract Payments”). Deferred Contract Payments, if any, shall be due on the next succeeding Payment Date except to the extent that payment is deferred pursuant to this Section 5.12. No Contract Payments may be deferred to a date that is after the Stock Purchase Date and no such deferral period may end other than on a Payment Date. If the Stock Purchase Contracts are terminated upon the occurrence of a Termination Event, the Holder’s right to receive Contract Payments, if any, and any Deferred Contract Payments, will terminate.

(b) In the event that the Company elects to defer the payment of Contract Payments on the Stock Purchase Contracts until a Payment Date prior to the Stock Purchase Date, then all Deferred Contract Payments, if any, shall be payable to the registered Holders as of the close of business on the Record Date immediately preceding such Payment Date.

(c) In the event that the Company elects to defer the payment of Contract Payments on the Stock Purchase Contracts until the Stock Purchase Date, each Holder will receive on the Stock Purchase Date in lieu of a cash payment, in the sole discretion of the Company, either (i) a number of shares of Common Stock (in addition to a number of shares of Common Stock equal to the Settlement Rate) equal to (A) the aggregate amount of Deferred Contract Payments payable to such Holder (net of any required tax withholding on such Deferred Contract Payment, which shall be remitted to the appropriate taxing jurisdiction) divided by (B) the greater of (x) the Applicable Market Value (or if the Stock Purchase Date shall be deferred beyond August 15, 2007, the Closing Price of Common Stock on the Trading Day immediately preceding the Stock Purchase Date) and (y) $12.44, subject to adjustment in the same manner and under the same circumstances as the Settlement Rate pursuant to Section 5.04, or (ii) Unsecured Notes which will (A) have a principal amount equal to the aggregate amount of Deferred Contract Payments, (B) mature on August 15, 2009, (C) bear interest at an annual rate equal to the Company’s then market rate of interest (not to exceed 10%), as determined by a nationally recognized investment banking firm selected for this purpose by the Company, (D) be subordinate and rank junior in right of payment to all of the Company’s Senior Debt on the same basis as the Contract Payments, and (E) not be redeemable by the Company prior to their stated maturity.

(d) No fractional shares of Common Stock will be issued by the Company with respect to the payment of Deferred Contract Payments on the Stock Purchase Date. In lieu of fractional shares otherwise issuable with respect to such payment of Deferred Contract Payments, the Holder will be entitled to receive an amount in cash as provided in Section 5.09.

(e) In the event the Company exercises its option to defer the payment of Contract Payments then, until the earlier of (x) the Termination Date or (y) the date on which the Deferred Contract Payments have been paid, the Company shall not (A) declare or pay dividends on, make distributions

Section 6.01 Unconditional Right of Holders to Receive Contract Payments and to Purchase Shares of Common Stock.

Each Holder of a Common SPACES shall have the right, which is absolute and unconditional, (i) subject to Article V, to receive each Contract Payment with respect to the Stock Purchase Contract comprising part of such Common SPACES on the respective Payment Date for such Common SPACES and (ii) except upon and following a Termination Event, to purchase shares of Common Stock pursuant to such Stock Purchase Contract and, in each such case, to institute suit for the enforcement of any such right to receive Contract Payments and the right to purchase shares of Common Stock, and such rights shall not be impaired without the consent of such Holder.

If any Holder has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding, the Company and such Holder shall be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of such Holder shall continue as though no such proceeding had been instituted.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates in the last paragraph of Section 3.10, no right or remedy herein conferred upon or reserved to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

No delay or omission of any Holder to exercise any right upon a default or remedy upon a default shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article VI or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by such Holders.

All parties to this Agreement agree, and each Holder of a Common SPACES, by its acceptance of such Common SPACES shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Stock Purchase Contract Agent for any action taken, suffered or omitted by it as Stock Purchase Contract Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and costs against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section shall not apply to any suit instituted by the Stock Purchase Contract Agent, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the Outstanding Common SPACES, or to any suit instituted by any Holder for the enforcement of interest on any STACKS or Contract Payments on or after the respective Payment Date therefor in respect of any Common SPACES held by such Holder, or for enforcement of the right to purchase shares of Common Stock under the Stock Purchase Contracts constituting part of any Common SPACES held by such Holder.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time 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 (to the extent that it may lawfully do so) hereby expressly waives 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 Stock Purchase Contract Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted.

(i) undertakes to perform, with respect to the Common SPACES, such duties and only such duties as are or will be specifically set forth in this Agreement, the Pledge Agreement and the Remarketing Agreement and no implied covenants or obligations shall be read into this Agreement, the Pledge Agreement or the Remarketing Agreement against the Stock Purchase Contract Agent; and

(ii) in the absence of bad faith or gross negligence on its part, may, with respect to the Common SPACES, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Stock Purchase Contract Agent and conforming to the requirements of this Agreement or the Pledge Agreement or the Remarketing Agreement, as applicable, but in the case of any certificates or opinions which by any provision hereof are specifically required to be furnished to the Stock Purchase Contract Agent, the Stock Purchase Contract Agent shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Agreement, the Pledge Agreement or the Remarketing Agreement, as applicable (but need not confirm or investigate the accuracy of the mathematical calculations or other facts stated therein).

(b) No provision of this Agreement, the Pledge Agreement or the Remarketing Agreement shall be construed to relieve the Stock Purchase Contract Agent from liability for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that:

(i) this subsection shall not be construed to limit the effect of subsection (a) of this Section;

(ii) the Stock Purchase Contract Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be conclusively determined by a court of competent jurisdiction that the Stock Purchase Contract Agent was grossly negligent in ascertaining the pertinent facts; and

(iii) no provision of this Agreement or the Pledge Agreement or the Remarketing Agreement shall require the Stock Purchase Contract Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(c) Whether or not therein expressly so provided, every provision of this Agreement, the Pledge Agreement and the Remarketing Agreement relating to the conduct or affecting the liability of or affording protection to the Stock Purchase Contract Agent shall be subject to the provisions of this Section.

(g) the Stock Purchase Contract Agent shall be under no obligation to exercise any of the rights or powers vested in it by this Agreement at the request or direction of any of the Holders pursuant to this Agreement, unless such Holders shall have offered to the Stock Purchase Contract Agent security or indemnity reasonably satisfactory to the Stock Purchase Contract Agent against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction;

(h) the Stock Purchase Contract Agent shall not be liable for any action taken, suffered, or omitted to be taken by it in the absence of bad faith or gross negligence by it;

(i) the Stock Purchase Contract Agent shall not be deemed to have notice of any default hereunder unless a Responsible Officer of the Stock Purchase Contract Agent has actual knowledge thereof or unless written notice of any event that is in fact such a default is received by the Stock Purchase Contract Agent at the Corporate Trust Office of the Stock Purchase Contract Agent, and such notice references the Common SPACES and this Agreement;

(j) the Stock Purchase Contract Agent may request that the Company deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Agreement, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded;

(k) the rights, privileges, protections, immunities and benefits given to the Stock Purchase Contract Agent, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Stock Purchase Contract Agent in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder; and

(l) the Stock Purchase Contract Agent shall not be required to initiate or conduct any litigation or collection proceedings hereunder and shall have no responsibilities with respect to any default hereunder except as expressly set forth herein.

The recitals contained herein, in the Pledge Agreement, the Remarketing Agreement and in the Certificates shall be taken as the statements of the Company, and the Stock Purchase Contract Agent assumes no responsibility for their accuracy or validity.

The provisions of this Section shall survive the resignation and removal of the Stock Purchase Contract Agent and the termination of this Agreement.

There shall at all times be a Stock Purchase Contract Agent hereunder which shall be a Person organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers, having (or being a member of a bank holding company having) a combined capital and surplus of at least $50,000,000, subject to supervision or examination by Federal or State authority and having a corporate trust office in the Borough of Manhattan, New York City, if there be such a Person in the Borough of Manhattan, New York City, qualified and eligible under this Article VII and willing to act on reasonable terms. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most

recent report of condition so published. If at any time the Stock Purchase Contract Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article VII.

(a) No resignation or removal of the Stock Purchase Contract Agent and no appointment of a successor Stock Purchase Contract Agent pursuant to this Article VII shall become effective until the acceptance of appointment by the successor Stock Purchase Contract Agent in accordance with the applicable requirements of Section 7.10.

(b) The Stock Purchase Contract Agent may resign at any time by giving written notice thereof to the Company 60 days prior to the effective date of such resignation. If the instrument of acceptance by a successor Stock Purchase Contract Agent required by Section 7.10 shall not have been delivered to the Stock Purchase Contract Agent within 30 days after the giving of such notice of resignation, the resigning Stock Purchase Contract Agent may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Stock Purchase Contract Agent.

(i) the Stock Purchase Contract Agent fails to comply with Section 310(b) of the TIA, as if the Stock Purchase Contract Agent were an indenture trustee under an indenture qualified under the TIA, and shall fail to resign after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Common SPACES for at least six months;

(ii) the Stock Purchase Contract Agent shall cease to be eligible under Section 7.8 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Stock Purchase Contract Agent shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Stock Purchase Contract Agent or of its property shall be appointed or any public officer shall take charge or control of the Stock Purchase Contract Agent or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the Company by a Board Resolution may remove the Stock Purchase Contract Agent, or (ii) any Holder who has been a bona fide Holder of a Common SPACES for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Stock Purchase Contract Agent and the appointment of a successor Stock Purchase Contract Agent.

If no successor Stock 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 Common SPACES for at least six months, on behalf of itself and all others similarly situated, or the Stock Purchase Contract Agent may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Stock Purchase Contract Agent.

(f) The Company shall give, or shall cause such successor Stock Purchase Contract Agent to give, notice of each resignation and each removal of the Stock Purchase Contract Agent and each appointment of a successor Stock Purchase Contract Agent by mailing written notice of such event by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the applicable Security Register. Each notice shall include the name of the successor Stock Purchase Contract Agent and the address of its Corporate Trust Office.

(a) In case of the appointment hereunder of a successor Stock Purchase Contract Agent, every such successor Stock Purchase Contract Agent so appointed shall execute, acknowledge and deliver to the Company and to the retiring Stock Purchase Contract Agent an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Stock Purchase Contract Agent shall become effective and such successor Stock Purchase Contract Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of the retiring Stock Purchase Contract Agent; but, on the request of the Company or the successor Stock Purchase Contract Agent, such retiring Stock Purchase Contract Agent shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Stock Purchase Contract Agent all the rights, powers and trusts of the retiring Stock Purchase Contract Agent and duly assign, transfer and deliver to such successor Stock Purchase Contract Agent all property and money held by such retiring Stock Purchase Contract Agent hereunder.

(b) Upon request of any such successor Stock Purchase Contract Agent, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Stock Purchase Contract Agent all such rights, powers and agencies referred to in subsection (a) of this Section.

(c) No successor Stock Purchase Contract Agent shall accept its appointment unless at the time of such acceptance such successor Stock Purchase Contract Agent shall be qualified and eligible under this Article VII.

Any Person into which the Stock Purchase Contract Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Stock Purchase Contract Agent shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Stock Purchase Contract Agent, shall be the successor of the Stock Purchase Contract Agent hereunder, provided that such Person shall be otherwise qualified and eligible under this Article VII, 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 Stock Purchase Contract Agent then in office, any successor by merger, conversion or consolidation to such Stock 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 Stock Purchase Contract Agent had itself authenticated and executed such Common SPACES.

(a) The Stock Purchase Contract Agent shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders received by the Stock Purchase Contract Agent in its capacity as Security Registrar.

(b) If three or more Holders (herein referred to as “Applicants”) apply in writing to the Stock Purchase Contract Agent, and furnish to the Stock Purchase Contract Agent reasonable proof that each such applicant has owned a Common SPACES 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 Common SPACES and is accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, then the Stock Purchase Contract Agent shall mail to all the Holders copies of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Stock Purchase Contract Agent of the materials to be mailed and of payment, or provision for the payment, of the reasonable expenses of such mailing.

Except to the extent otherwise expressly provided in this Agreement, the Stock Purchase Contract Agent assumes no obligations and shall not be subject to any liability under this Agreement, the Pledge Agreement, the Remarketing Agreement or any Stock Purchase Contract in respect of the obligations of the Holder of any Common SPACES thereunder. The Company agrees, and each Holder of a Certificate, by its acceptance thereof, shall be deemed to have agreed, that the Stock 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 Stock Purchase Contract Agent shall have no obligation to perform such Stock Purchase Contracts on behalf of the Holders, except to the extent expressly provided in Article V hereof. Anything contained in this Agreement to the contrary notwithstanding, in no event shall the Stock Purchase Contract Agent or its officers, directors, employees or agents be liable under this Agreement, the Pledge Agreement or the Remarketing Agreement to any third party for indirect, incidental, special, punitive, or consequential loss or damage of any kind whatsoever, including lost profits, whether or not the likelihood of such loss or damage was known to the Stock Purchase Contract Agent and regardless of the form of action.

(a) The Stock Purchase Contract Agent, on its own behalf and on behalf of the Company, will comply with all applicable certification, information reporting and withholding (including “backup” withholding) requirements imposed by applicable tax laws, regulations or administrative practice with respect to (i) any payments made with respect to the Common SPACES or (ii) the issuance, delivery, holding, transfer, redemption or exercise of rights under the Common SPACES. Such compliance shall include, without limitation, the preparation and timely filing of required returns and the timely payment of all amounts required to be withheld to the appropriate taxing authority or its designated agent.

(b) The Stock Purchase Contract Agent shall comply in accordance with the terms hereof with any 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 7.01(a) hereof.

(c) The Stock 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 or its authorized representative within a reasonable period of time after receipt of such request.

Without the consent of any Holders, the Company, when authorized by a Board Resolution, and the Stock Purchase Contract Agent, at any time and from time to time, may enter into one or more agreements supplemental hereto, in form satisfactory to the Company and the Stock Purchase Contract Agent, to:

(a) evidence the succession of another Person to the Company, and the assumption by any such successor of the covenants of the Company herein and in the Certificates;

(b) add to the covenants of the Company for the benefit of the Holders, or surrender any right or power herein conferred upon the Company;

(d) make provision with respect to the rights of Holders pursuant to the requirements of Section 5.04(b);

(f) make any other provisions with respect to such matters or questions arising under this Agreement, provided that such action shall not adversely affect the interests of the Holders in any material respect.

With the consent of the Holders of not less than a majority of the Outstanding Common SPACES voting together as one class, including without limitation the consent of the Holders obtained in connection with a tender or an exchange offer, by Act of said Holders delivered to the Company and the Stock Purchase Contract Agent, the Company, when duly authorized, and the Stock Purchase Contract Agent may enter into an agreement or agreements supplemental hereto for the purpose of modifying in any manner the terms of the Stock Purchase Contracts, or the provisions of this Agreement or the rights of the Holders in respect of the Common SPACES; provided, however, that, except as contemplated herein, no such supplemental agreement shall, without the unanimous consent of the Holders of each outstanding Stock Purchase Contract affected thereby,

(b) change the amount or the type of Collateral required to be Pledged to secure a Holder’s obligations under the Stock Purchase Contract, impair the right of the Holder of any Stock Purchase

Contract to receive distributions on the related Collateral or otherwise adversely affect the Holder’s rights in or to such Collateral or adversely alter the rights in or to such Collateral;

(c) reduce any Contract Payments or change any place where, or the coin or currency in which, any Contract Payment is payable;

(d) impair the right to institute suit for the enforcement of any Stock Purchase Contract or any Contract Payments;

(e) reduce the number of shares of Common Stock or the amount of any other property to be purchased pursuant to any Stock Purchase Contract, increase the price to purchase shares of Common Stock or any other property upon settlement of any Stock Purchase Contract or change the Stock Purchase Date or the right to Early Settlement or Cash Merger Early Settlement or otherwise adversely affect the Holder’s rights under the Stock Purchase Contract; or

(f) reduce the percentage of the outstanding Stock Purchase Contracts the consent of whose Holders is required for any modification or amendment to the provisions of this Agreement, the Stock Purchase Contracts or the Pledge Agreement;

provided that if any amendment or proposal referred to above would adversely affect only the Normal Common SPACES or the Stripped Common SPACES, then only the affected class of Holders as of the record date for the Holders entitled to vote thereon will be entitled to vote on such amendment or proposal, and such amendment or proposal shall not be effective except with the consent of Holders of not less than a majority of such class; and provided, further, that the unanimous consent of the Holders of each outstanding Stock Purchase Contract of such class affected thereby shall be required to approve any amendment or proposal specified in clauses (a) through (f) above.

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental agreement, but it shall be sufficient if such Act shall approve the substance thereof.

In executing, or accepting the additional agencies created by, any supplemental agreement permitted by this Article VIII or the modifications thereby of the agencies created by this Agreement, the Stock Purchase Contract Agent shall be provided, and (subject to Section 7.01) shall be fully authorized and protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such supplemental agreement is authorized or permitted by this Agreement and that any and all conditions precedent to the execution and delivery of such supplemental agreement have been satisfied.

Upon the execution of any supplemental agreement under this Article VIII, this Agreement shall be modified in accordance therewith, and such supplemental agreement shall form a part of this Agreement for all purposes; and every Holder of Certificates theretofore or thereafter authenticated, executed on behalf of the Holders and delivered hereunder, shall be bound thereby.

Certificates authenticated, executed on behalf of the Holders and delivered after the execution of any supplemental agreement pursuant to this Article VIII may, and shall if required by the Stock Purchase Contract Agent, bear a notation in form approved by the Stock Purchase Contract Agent as to any matter provided for in such supplemental agreement. If the Company shall so determine, new Certificates so modified as to conform, in the opinion of the Stock Purchase Contract Agent and the Company, to any such supplemental agreement may be prepared and executed by the Company and authenticated, executed on behalf of the Holders and delivered by the Stock Purchase Contract Agent in exchange for outstanding Certificates.

Section 9.01 Covenant Not to Consolidate, Merge, Convey, Transfer or Lease Property Except under Certain Conditions.

The Company covenants that it will not consolidate with, convert into, or merge with and into, any other corporation or sell, assign, transfer, lease or convey all or substantially all of its properties and assets to any Person, unless:

(a) either the Company shall be the continuing corporation, or the successor (if other than the Company) shall be a corporation organized and existing under the laws of the United States of America or a State thereof or the District of Columbia and such corporation shall expressly assume all the obligations of the Company under the Stock Purchase Contracts, this Agreement, the Pledge Agreement, the Trust Agreement, the Indenture (including any supplement thereto) and the Remarketing Agreement by one or more supplemental agreements in form reasonably satisfactory to the Stock Purchase Contract Agent and the Collateral Agent, executed and delivered to the Stock Purchase Contract Agent and the Collateral Agent by such corporation; and

(b) the Company or such successor corporation, as the case may be, shall not, immediately after such consolidation, conversion, merger, sale, assignment, transfer, lease or conveyance, be in default of payment obligations under the Stock Purchase Contracts, this Agreement, the Pledge Agreement, the Indenture (including any supplement thereto), the Trust Agreement, or the Remarketing Agreement or in material default in the performance of any other covenants under any of the foregoing agreements.

In case of any such merger, consolidation, share exchange, sale, assignment, transfer, lease or conveyance and upon any such assumption by a successor corporation in accordance with Section 9.01, such successor corporation shall succeed to and be substituted for the Company with the same effect as if it had been named herein as the Company. Such successor corporation thereupon may cause to be signed, and may issue either in its own name or in the name of the Company, any or all of the Certificates evidencing Common SPACES issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Stock Purchase Contract Agent; and, upon the order of such successor corporation, instead of the Company, and subject to all the terms, conditions and limitations in this Agreement prescribed, the Stock Purchase Contract Agent shall authenticate and execute on behalf of the Holders and deliver any Certificates which previously shall have been signed and delivered by the officers of the Company to the Stock Purchase Contract Agent for authentication and execution, and any Certificate evidencing Common SPACES which such successor corporation thereafter shall cause to be

signed and delivered to the Stock Purchase Contract Agent or that purpose. All the Certificates issued shall in all respects have the same legal rank and benefit under this Agreement as the Certificates theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Certificates had been issued at the date of the execution hereof.

In case of any such merger, consolidation, share exchange, sale, assignment, transfer, lease or conveyance, such change in phraseology and form (but not in substance) may be made in the Certificates evidencing Common SPACES thereafter to be issued as may be appropriate.

Section 9.03 Officers’ Certificate and Opinion of Counsel Given to Stock Purchase Contract Agent.

The Stock Purchase Contract Agent, subject to Section 7.01 and Section 7.03, shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such merger, consolidation, share exchange, sale, assignment, transfer, lease or conveyance, and any such assumption, complies with the provisions of this Article IX and that all conditions precedent to the consummation of any such merger, consolidation, share exchange, sale, assignment, transfer, lease or conveyance have been met.

The Company covenants and agrees for the benefit of the Holders from time to time of the Common SPACES that it will duly and punctually perform its obligations under the Stock Purchase Contracts in accordance with the terms of the Stock Purchase Contracts and this Agreement.

The Company will maintain in the Borough of Manhattan, New York City an office or agency where Certificates may be presented or surrendered for acquisition of shares of Common Stock upon settlement of the Stock Purchase Contracts on the Stock Purchase Date or upon Early Settlement or Cash Merger Early Settlement and for transfer of Collateral upon occurrence of a Termination Event, where Certificates may be surrendered for registration of transfer or exchange, for a Collateral Substitution or recreation of Normal Common SPACES and where notices and demands to or upon the Company in respect of the Common SPACES and this Agreement may be served. The Company will give prompt written notice to the Stock Purchase Contract Agent of the location, and any change in the location, of such office or agency. The Company initially designates the Corporate Trust Office of the Stock Purchase Contract Agent as such office of the Company. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Stock Purchase Contract Agent with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Company hereby appoints the Stock Purchase Contract Agent as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies where Certificates may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, New York City for such purposes. The Company will give prompt written notice to the Stock Purchase

Contract Agent of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates as the place of payment for the Common SPACES the Corporate Trust Office and appoints the Stock Purchase Contract Agent at its Corporate Trust Office as paying agent in such city.

The Company shall at all times prior to the Stock Purchase Date reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock the full number of shares of Common Stock issuable against tender of payment in respect of all Stock Purchase Contracts constituting a part of the Common SPACES evidenced by Outstanding Certificates.

The Company covenants that all shares of Common Stock which may be issued against tender of payment in respect of any Stock Purchase Contract constituting a part of the Outstanding Common SPACES will, upon issuance, be duly authorized, validly issued, fully paid and nonassessable.

The Company will deliver to the Stock Purchase Contract Agent, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions hereof, and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

Each Holder from time to time of the Common SPACES that is a Plan or who used assets of a Plan to purchase Common SPACES hereby represents that either (i) no portion of the assets used by such Holder to acquire the Normal Common SPACES constitutes assets of the Plan or (ii) the purchase or holding of the Normal Common SPACES by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable laws.

(a) The Company covenants and agrees, for United States federal, state and local income and franchise tax purposes, to (i) treat a Holder’s acquisition of the Normal Common SPACES as the acquisition of the STACKS and Stock Purchase Contract constituting the Normal Common SPACES and (ii) treat each Holder as the owner of the applicable interest in the Collateral Account, including the STACKS or the Treasury Securities.

(b) Each Holder of Common SPACES agrees, by acceptance of Common SPACES, and each Beneficial Owner agrees, by acceptance of a beneficial interest in Common SPACES, to treat for all United States federal income tax purposes (i) itself as the owner of the Stock Purchase Contracts and the related ownership interest in the STACKS or Treasury Securities, as applicable, pledged under the Pledge Agreement, (ii) the Debentures as indebtedness of the Company, and (iii) the fair market value of each undivided beneficial interest in each $1,000 Initial Liquidation Amount of STACKS included in Normal Common SPACES as $1,000 and the fair market value of each Stock Purchase Contract as $0.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the day and year first above written.

This Normal Common SPACES Certificate certifies that {Cede & Co.} is the registered Holder of the number of Normal Common SPACES set forth above {for inclusion in Global Certificates only - or such other number of Normal Common SPACES reflected in the Schedule of Increases or Decreases in the Global Certificate attached hereto}.

The Company shall pay, on each Payment Date, in respect of each Stock Purchase Contract forming part of a Normal Common SPACES evidenced hereby, an amount (the “Contract Payments”) equal to 2.60% per year of the Stated Amount, subject to its rights provided for in the Stock Purchase Contract Agreement to defer Contract Payments. Such Contract Payments shall be payable to the Person in whose name this Normal Common SPACES Certificate is registered at the close of business on the Record Date for such Payment Date.

Distributions on the STACKS and the Contract Payments will be payable at the office of the Stock Purchase Contract Agent in New York City.

This is one of the Normal Common SPACES Certificates referred to in the within mentioned Stock Purchase Contract Agreement.

By:

BNY MIDWEST TRUST COMPANY,

as Stock Purchase Contract Agent


By:

Title:

Each Stock Purchase Contract evidenced hereby is governed by a Stock Purchase Contract Agreement, dated as of July 29, 2004 (as may be supplemented from time to time, the “STOCK PURCHASE CONTRACT AGREEMENT”), between the Company and BNY Midwest Trust Company, as Stock Purchase Contract Agent (including its successors hereunder, the “STOCK PURCHASE CONTRACT AGENT”), to which Stock 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 Stock Purchase Contract Agent, the Company, and the Holders and of the terms upon which the Normal Common SPACES Certificates are, and are to be, executed and delivered.

Each Stock Purchase Contract evidenced hereby obligates the Holder of this Normal Common SPACES Certificate to purchase, and the Company to sell, on the Stock Purchase Date at a price equal to $25 (the “PURCHASE PRICE”), a number of shares of Common Stock equal to the Settlement Rate, unless an Early Settlement, a Cash Merger Early Settlement or a Termination Event with respect to the Common SPACES of which such Stock Purchase Contract is a part shall have occurred. The “SETTLEMENT RATE” is equal to:

(1) if the Adjusted Applicable Market Value (as defined below) is greater than or equal to $46.28 (the “THRESHOLD APPRECIATION PRICE”), 0.5402 shares of Common Stock per Stock Purchase Contract, (such number of shares, as adjusted from time to time pursuant to Section 5.04, the “MINIMUM SHARE NUMBER”);

(2) if the Adjusted Applicable Market Value is less than the Threshold Appreciation Price but greater than $37.32 (the “REFERENCE PRICE”), the number of shares of Common Stock per Stock Purchase Contract having a value equal to the Stated Amount divided by the Adjusted Applicable Market Value; and

(3) if the Adjusted Applicable Market Value is less than or equal to the Reference Price, 0.6699 shares of Common Stock per Stock Purchase Contract, (such number of shares, as adjusted from time to time pursuant to Section 5.04, the “MAXIMUM SHARE NUMBER”),

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

No fractional shares of Common Stock will be issued upon settlement of Stock Purchase Contracts, as provided in Section 5.09 of the Stock Purchase Contract Agreement.

Each Stock Purchase Contract evidenced hereby, which is settled through Early Settlement or Cash Merger Early Settlement, shall obligate the Holder of the related Normal Common SPACES to purchase at the Purchase Price, and the Company to sell, a number of newly issued or treasury shares of Common Stock equal to the Early Settlement Rate (in the case of an Early Settlement) or applicable Settlement Rate (in the case of a Cash Merger Early Settlement).

The “ADJUSTED APPLICABLE MARKET VALUE” means (i) prior to any adjustment pursuant to paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a) of the Stock Purchase Contract Agreement, the Applicable Market Value, and (ii) at the time of and after any adjustment of each Fixed Settlement Rate pursuant to paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a) of the Stock Purchase Contract Agreement, the Applicable Market Value multiplied by the Adjustment Factor.

The “ADJUSTMENT FACTOR” means a fraction the numerator of which shall be the Maximum Share Number immediately after such adjustment pursuant to paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a) of the Stock Purchase Contract Agreement and the denominator of which shall be the Maximum Share Number immediately prior to such adjustment; provided, however, that if such adjustment to each Fixed Settlement Rate is required to be made pursuant to the occurrence of any of the events contemplated by paragraph (i), (ii), (iii), (iv), (v), (vi), (vii) or (x) of Section 5.04(a) of the Stock Purchase Contract Agreement during the period taken into consideration for determining the Applicable Market Value, the 20 individual Closing Prices used to determine the Applicable Market Value shall be adjusted rather than the Applicable Market Value and the Applicable Market Value shall be determined by (A) multiplying the Closing Prices for Trading Days prior to such adjustment to each Fixed Settlement Rate by the Adjustment Factor in effect prior to such adjustment, (B) multiplying the Closing Prices for Trading Days following such adjustment by the Adjustment Factor reflecting such adjustment, and (C) dividing the sum of all such adjusted Closing Prices by 20.

The “APPLICABLE MARKET VALUE” means the average of the Closing Price per share of Common Stock on each of the 20 consecutive Trading Days ending on the third Trading Day immediately preceding August 15, 2007.

The “CLOSING PRICE” per share of Common Stock on any date of determination means:

(1) the closing sale price as of the close of the principal trading session (or, if no closing price is reported, the last reported sale price) per share on the New York Stock Exchange, Inc. (the “NYSE”) on such date;

(2) if Common Stock is not listed for trading on the NYSE on any such date, the closing sale price (or, if no closing price is reported, the last reported sale price) per share as reported in the composite transactions for the principal United States national or regional securities exchange on which Common Stock is so listed;

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

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

(5) if the bid price referred to above is not available, the market value of Common Stock on such date as determined by a nationally recognized independent investment banking firm retained by the Company for purposes of determining the Closing Price.

A “TRADING DAY” means a day on which 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 over-the-counter market that is the primary market for the trading of Common Stock.

In accordance with the terms of the Stock Purchase Contract Agreement, the Holder of this Normal Common SPACES Certificate may pay the Purchase Price for the shares of Common Stock purchased pursuant to each Stock Purchase Contract evidenced hereby by effecting a Cash Settlement, an Early Settlement or, if applicable, a Cash Merger Early Settlement or from the proceeds of or a Remarketing of the related Pledged STACKS. A Holder of Normal Common SPACES who (1) does not, on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Stock

Purchase Date, notify the Stock Purchase Contract Agent of its intention to effect a Cash Settlement, or who does so notify the Stock Purchase Contract Agent but fails to make an effective Cash Settlement on or prior to 5:00 p.m. (New York City time) on the fourth Business Day immediately preceding the Stock Purchase Date, or (2) on or prior to 5:00 p.m. (New York City time) on the fifth Business Day prior to the Stock Purchase Date, does not make an effective Early Settlement, shall pay the Purchase Price for the shares of Common Stock to be delivered under the related Stock Purchase Contract from the proceeds of the sale of the related Pledged STACKS held by the Collateral Agent in the Remarketing unless the Holder has previously made a Cash Merger Early Settlement. Such sale will be made by the Remarketing Agent pursuant to the terms of the Remarketing Agreement on the applicable Remarketing Date.

Upon the occurrence of a Failed Remarketing with respect to the August 15, 2008 Remarketing Settlement Date, the Collateral Agent, for the benefit of the Company, will exercise its rights as a secured party with respect to the Pledged STACKS underlying the Normal Common SPACES, and may, among other things, (A) retain such STACKS in full satisfaction of the Holders’ obligations under the Stock Purchase Contracts or (B) sell such STACKS in one or more public or private sales or otherwise. In the event of a Failed Remarketing with respect to the August 15, 2008 Remarketing Settlement Date, the Company will issue a note, payable on August 15, 2009 and bearing interest at the rate of 3.90%, in the amount of any accrued and unpaid distributions on such Pledged STACKS as of August 15, 2008, to the Stock Purchase Contract Agent for delivery to the Holders of such STACKS.

The Company shall not be obligated to issue any shares of Common Stock in respect of a Stock 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 Stock Purchase Contract Agreement.

Under the terms of the Pledge Agreement and the Stock Purchase Contract Agreement, the Stock Purchase Contract Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged STACKS, but only to the extent instructed in writing by the Holders. Upon receipt of notice of any meeting at which holders of STACKS are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of STACKS, the Stock Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage pre-paid, to the Normal Common SPACES Holders a notice:

(2) stating that each Holder on the record date set by the Stock Purchase Contract Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of STACKS, as the case may be, entitled to vote) shall be entitled to instruct the Stock Purchase Contract Agent as to the exercise of the voting rights pertaining to the STACKS underlying such Holder’s Normal Common SPACES; and

Upon the written request of the Normal Common SPACES Holders on such record date received by the Stock Purchase Contract Agent at least six days prior to such meeting, the Stock 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 liquidation amount of STACKS, as the case may be, as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of a Normal Common SPACES, the Stock Purchase Contract Agent shall abstain from voting the STACKS evidenced by such Normal Common SPACES. The Company hereby agrees, if applicable, to solicit Holders of Normal Common SPACES to timely instruct the Stock

Purchase Contract Agent in order to enable the Stock Purchase Contract Agent to vote the STACKS. The Holders of Normal Common SPACES shall have no voting or other rights in respect of Common Stock.

Upon the occurrence of a Successful Remarketing, the Collateral Agent shall, in accordance with the Pledge Agreement, cause the Securities Intermediary to transfer the Pledged STACKS upon confirmation of deposit by the Remarketing Agent of the proceeds of such Successful Remarketing in the Collateral Account. The Remarketing Agent will deduct a remarketing fee in accordance with the terms of the Remarketing Agreement. With respect to Pledged STACKS upon a Successful Remarketing, any proceeds of the Remarketing in excess of the aggregate Purchase Price applicable to the related Normal Common SPACES plus the portion of the Remarketing Fee attributable to such Pledged STACKS will be remitted to the Stock Purchase Contract Agent for payment to the Holders of the related Normal Common SPACES.

The Normal Common SPACES Certificates are issuable only in registered form and only in denominations of a single Normal Common SPACES and any integral multiple thereof. The transfer of any Normal Common SPACES Certificate will be registered and Normal Common SPACES Certificates may be exchanged as provided in the Stock Purchase Contract Agreement. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Stock Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Stock 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 a STACKS, thereby creating Stripped Common SPACES, shall be responsible for any fees or expenses payable in connection therewith. Except as provided in the Stock Purchase Contract Agreement, for so long as the Stock Purchase Contract underlying a Normal Common SPACES remains in effect, such Normal Common SPACES shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Normal Common SPACES in respect of the STACKS and Stock Purchase Contract constituting such Normal Common SPACES may be transferred and exchanged only as a Normal Common SPACES.

Subject to the conditions set forth in the Stock Purchase Contract Agreement, a Holder may, at any time on or prior to 5:00 p.m. (New York City time) on the seventh Business Day immediately preceding the Applicable Remarketing Settlement Date, effect a Collateral Substitution and separate the Pledged STACKS from the related Stock Purchase Contracts in respect of all or a portion of such Holder’s Normal Common SPACES by substituting for such Pledged STACKS, Treasury Securities or portions thereof in an aggregate liquidation amount at maturity equal to the aggregate liquidation amount of such Pledged STACKS; provided that Holders may make Collateral Substitutions only in integral multiples of 40 Normal Common SPACES.

The Company shall pay, on each Payment Date, the Contract Payments payable in respect of each Stock Purchase Contract to the Person in whose name the Normal Common SPACES Certificate evidencing such Stock Purchase Contract is registered at the close of business on the Record Date for such Payment Date. Contract Payments will be payable at the office of the Stock Purchase Contract Agent in New York City. If the book-entry system for the Normal Common SPACES has been terminated, the Contract Payments will be payable, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or by wire transfer to the account designated by such Person by a prior written notice to the Stock Purchase Contract Agent.

The Company shall have the right, at any time prior to the Stock Purchase Date, to defer the payment of any or all of the Contract Payments otherwise payable on any Payment Date, but only if the Company shall give the Holders and the Stock Purchase Contract Agent written notice of its election to defer each such deferred Contract Payment pursuant to Section 5.12 of the Stock Purchase Contract

Agreement. Any Contract Payments so deferred shall, to the extent permitted by law, accrue additional Contract Payments thereon at the rate of 6.50% per year (computed on the basis of a 360-day year of twelve 30-day months), compounding on each succeeding Payment Date, until paid in full (such deferred installments of Contract Payments, if any, together with the additional Contract Payments, if any, accrued thereon, being referred to herein as the “Deferred Contract Payments”). Deferred Contract Payments, if any, shall be due on the next succeeding Payment Date except to the extent that payment is deferred pursuant to the Section 5.12 of the Stock Purchase Contract Agreement. No Contract Payments may be deferred to a date that is after the Stock Purchase Date and no such deferral period may end other than on a Payment Date. If the Stock Purchase Contracts are terminated upon the occurrence of a Termination Event, the Holder’s right to receive Contract Payments, if any, and any Deferred Contract Payments, will terminate.

The Stock 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 any Contract Payments, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Stock Purchase Contract Agent or the Company, if, on or prior to the Stock Purchase 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 Stock Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged STACKS from the Pledge in accordance with the provisions of the Pledge Agreement. A Normal Common SPACES shall thereafter represent the right to receive the STACKS forming a part of such Normal Common SPACES in accordance with the terms of, and except as set forth in, the Stock Purchase Contract Agreement and the Pledge Agreement.

Subject to and upon compliance with the provisions of the Stock Purchase Contract Agreement, at the option of the Holder thereof, Stock Purchase Contracts underlying Common SPACES may be settled early (“EARLY SETTLEMENT”) at any time on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Stock Purchase Date as provided in the Stock Purchase Contract Agreement. In order to exercise the right to effect Early Settlement with respect to any Stock Purchase Contract evidenced by this Certificate, the Holder of this Normal Common SPACES Certificate shall deliver to the Stock Purchase Contract Agent at the Corporate Trust Office prior to the time specified in the Stock Purchase Contract Agreement an Election to Settle Early form 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 the sum of:

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

(ii) 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 Contract Payments payable on such Payment Date with respect to such Stock Purchase Contracts.

Upon Early Settlement of Stock Purchase Contracts by a Holder of the related Common SPACES, the Pledged STACKS shall be released from the Pledge as provided in the Pledge Agreement and the Holder shall be entitled to receive a number of newly issued or treasury shares of Common Stock adjusted in the same manner and at the same time as the Settlement Rate is adjusted (the “EARLY SETTLEMENT RATE”).

Upon the occurrence of a Cash Merger, a Holder of Normal Common SPACES may effect Cash Merger Early Settlement of the Stock Purchase Contract underlying such Normal Common SPACES pursuant to the terms of Section 5.04(b)(ii) of the Stock Purchase Contract Agreement. Upon Cash Merger Early Settlement of Stock Purchase Contracts by a Holder of the related Normal Common SPACES, the Pledged STACKS underlying such Normal Common SPACES shall be released from the Pledge as provided in the Pledge Agreement.

Upon registration of transfer of this Normal Common SPACES 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 Stock Purchase Contract Agent pursuant to the Stock Purchase Contract Agreement), under the terms of the Stock Purchase Contract Agreement and the Stock Purchase Contracts evidenced hereby and the transferor shall be released from the obligations under the Stock Purchase Contracts evidenced by this Normal Common SPACES 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 Holder of this Normal Common SPACES Certificate, by its acceptance hereof, irrevocably authorizes the Stock Purchase Contract Agent to enter into and perform the related Stock Purchase Contracts forming part of the Normal Common SPACES evidenced hereby on its behalf as its attorney-in-fact, expressly withholds any consent to the assumption (i.e., affirmance) of the Stock 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 Stock Purchase Contracts, consents to the provisions of the Stock Purchase Contract Agreement, irrevocably authorizes the Stock Purchase Contract Agent to enter into and perform the Stock Purchase Contract Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and consents to, and agrees to be bound by, the Pledge of such Holder’s right, title and interest in and to the Collateral Account, including the STACKS underlying this Normal Common SPACES Certificate pursuant to the Pledge Agreement. The Holder further covenants and agrees that, to the extent and in the manner provided in the Stock Purchase Contract Agreement and the Pledge Agreement, but subject to the terms thereof, payments with respect to the aggregate liquidation amount of the Pledged STACKS on the Stock Purchase Date shall be paid by the Collateral Agent to the Company in satisfaction of such Holder’s obligations under such Stock Purchase Contract and such Holder shall acquire no right, title or interest in such payments.

Subject to certain exceptions, the provisions of the Stock Purchase Contract Agreement may be amended with the consent of the Holders of a majority of the Stock Purchase Contracts.

The Stock Purchase Contracts shall be governed by, and construed in accordance with, the laws of the State of New York.

Prior to due presentment of this Certificate for registration of transfer, the Company, the Stock Purchase Contract Agent and its Affiliates and any agent of the Company or the Stock Purchase Contract Agent may treat the Person in whose name this Normal Common SPACES Certificate is registered as the owner of the Normal Common SPACES evidenced hereby for the purpose of receiving distributions payable on the STACKS, receiving payments of Contract Payments (subject to any applicable record date), performance of the Stock 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 Stock Purchase Contract Agent nor any such agent shall be affected by notice to the contrary.

The Stock 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.

A copy of the Stock Purchase Contract Agreement is available for inspection at the offices of the Stock Purchase Contract Agent.

The following abbreviations, when used in the inscription on the face of this instrument, shall be construed as though they were written out in full according to applicable laws or regulations:

BNY MIDWEST TRUST COMPANY, as Stock Purchase Contract Agent

By:

Title:

Dated:

Each Stock Purchase Contract evidenced hereby is governed by a Stock Purchase Contract Agreement, dated as of July 29, 2004 (as may be supplemented from time to time, the “STOCK PURCHASE CONTRACT AGREEMENT”) between the Company and BNY Midwest Trust Company, as Stock Purchase Contract Agent (including its successors thereunder, herein called the “STOCK PURCHASE CONTRACT AGENT”), to which the Stock 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 Stock Purchase Contract Agent, the Company and the Holders and of the terms upon which the Stripped Common SPACES Certificates are, and are to be, executed and delivered.

Each Stock Purchase Contract evidenced hereby obligates the Holder of this Stripped Common SPACES Certificate to purchase, and the Company to sell, on the Stock Purchase Date at a price equal to $25 (the “PURCHASE PRICE”) a number of newly issued or treasury shares of Common Stock equal to the Settlement Rate, unless an Early Settlement, a Cash Merger Early Settlement or a Termination Event with respect to the Common SPACES of which such Stock Purchase Contract is a part shall have occurred. The “SETTLEMENT RATE” is equal to:

(1) if the Adjusted Applicable Market Value (as defined below) is greater than or equal to $46.28 (the “THRESHOLD APPRECIATION PRICE”), 0.5402 shares of Common Stock per Stock Purchase Contract (such number of shares, as adjusted from time to time pursuant to Section 5.04, the “MINIMUM SHARE NUMBER”);

(3) if the Adjusted Applicable Market Value is less than or equal to the Reference Price, 0.6699 shares of Common Stock per Purchase Contract (such number of shares, as adjusted from time to time pursuant to Section 5.04, the “MAXIMUM SHARE NUMBER”),

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

No fractional shares of Common Stock will be issued upon settlement of Stock Purchase Contracts, as provided in Section 5.09 of the Stock Purchase Contract Agreement.

Each Stock Purchase Contract evidenced hereby, which is settled through Early Settlement or Cash Merger Early Settlement shall obligate the Holder of the related Stripped Common SPACES to purchase at the Purchase Price, and the Company to sell, a number of newly issued or treasury shares of Common Stock equal to the Early Settlement Rate (in the case of an Early Settlement) or applicable Settlement Rate (in the case of a Cash Merger Early Settlement).

The “CLOSING PRICE” per share of Common Stock on any date of determination means:

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

In accordance with the terms of the Stock Purchase Contract Agreement, the Holder of this Stripped Common SPACES shall pay the Purchase Price for the shares of the Common Stock purchased pursuant to each Stock Purchase Contract evidenced hereby either by effecting an Early Settlement or, if applicable, a Cash Merger Early Settlement of each such Stock Purchase Contract or by applying a principal amount of the Pledged Treasury Securities underlying such Holder’s Stripped Common SPACES equal to the Stated Amount of such Stock Purchase Contract to the purchase of the Common

Stock. A Holder of Stripped Common SPACES who (1) on or prior to 5:00 p.m. (New York City time) on the fifth Business Day prior to the Stock Purchase Date, does not make an effective Early Settlement or (2) on or prior to 5:00 p.m. (New York City time) on the fifth Business Day prior to the Stock Purchase Date, does not make an effective Cash Merger Early Settlement, shall pay the Purchase Price for the shares of Common Stock to be issued under the related Stock Purchase Contract from the proceeds of the Pledged Treasury Securities.

The Company shall not be obligated to issue any shares of Common Stock in respect of a Stock 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 Stock Purchase Contract Agreement.

The Stripped Common SPACES Certificates are issuable only in registered form and only in denominations of a single Stripped Common SPACES and any integral multiple thereof. The transfer of any Stripped Common SPACES Certificate will be registered and Stripped Common SPACES Certificates may be exchanged as provided in the Stock Purchase Contract Agreement. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Stock Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Stock 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 STACKS for Treasury Securities, thereby recreating Normal Common SPACES, shall be responsible for any fees or expenses associated therewith. Except as provided in the Stock Purchase Contract Agreement, for so long as the Stock Purchase Contract underlying a Stripped Common SPACES remains in effect, such Stripped Common SPACES shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Stripped Common SPACES in respect of the Treasury Security and the Stock Purchase Contract constituting such Stripped Common SPACES may be transferred and exchanged only as a Stripped Common SPACES.

Subject to the conditions set forth in the Stock Purchase Contract Agreement, a Holder of Stripped Common SPACES may recreate, at any time on or prior to 5:00 p.m. (New York City time) on the seventh Business Day immediately preceding the Applicable Remarketing Settlement Date, Normal Common SPACES by delivering to the Securities Intermediary STACKS with an aggregate liquidation 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 Stock Purchase Contract Agreement and the Pledge Agreement. From and after such substitution, the Holder’s Common SPACES shall be referred to as a “NORMAL COMMON SPACES.” Any such creation of Normal Common SPACES may be effected only in multiples of 40 Stripped Common SPACES for 40 Normal Common SPACES.

The Company shall pay, on each Payment Date, the Contract Payments payable in respect of each Stock Purchase Contract to the Person in whose name the Stripped Common SPACES Certificate evidencing such Stock Purchase Contract is registered at the close of business on the Record Date for such Payment Date. Contract Payments will be payable at the office of the Stock Purchase Contract Agent in New York City. If the book-entry system for the Normal Common SPACES has been terminated, the Contract Payments will be payable, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person’s address as it appears on the Security Register, or by wire transfer to the account designated by such Person by a prior written notice to the Stock Purchase Contract Agent.

defer each such deferred Contract Payment pursuant to Section 5.12 of the Stock Purchase Contract Agreement. Any Contract Payments so deferred shall, to the extent permitted by law, accrue additional Contract Payments thereon at the rate of 6.50% per year (computed on the basis of a 360-day year of twelve 30-day months), compounding on each succeeding Payment Date, until paid in full (such deferred installments of Contract Payments, if any, together with the additional Contract Payments, if any, accrued thereon, being referred to herein as the “Deferred Contract Payments”). Deferred Contract Payments, if any, shall be due on the next succeeding Payment Date except to the extent that payment is deferred pursuant to the Section 5.12 of the Stock Purchase Contract Agreement. No Contract Payments may be deferred to a date that is after the Stock Purchase Date and no such deferral period may end other than on a Payment Date. If the Stock Purchase Contracts are terminated upon the occurrence of a Termination Event, the Holder’s right to receive Contract Payments, if any, and any Deferred Contract Payments, will terminate.

The Stock 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 any Contract Payments, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Stock Purchase Contract Agent or the Company, if, on or prior to the Stock Purchase 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 Stock Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Pledged Treasury Securities (as defined in the Pledge Agreement) in accordance with the provisions of the Pledge Agreement. A Stripped Common SPACES shall thereafter represent the right to receive the interest in the Treasury Security forming a part of such Stripped Common SPACES, in accordance with the terms of and except as set forth in, the Stock Purchase Contract Agreement and the Pledge Agreement.

Subject to and upon compliance with the provisions of the Stock Purchase Contract Agreement, at the option of the Holder thereof, Stock Purchase Contracts underlying Common SPACES may be settled early (“EARLY SETTLEMENT”) as provided in the Stock Purchase Contract Agreement. In order to exercise the right to effect Early Settlement with respect to any Stock Purchase Contract evidenced by this Certificate, the Holder of this Stripped Common SPACES Certificate shall deliver to the Stock Purchase Contract Agent at the Corporate Trust Office an Election to Settle Early form 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 the sum of:

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

Upon Early Settlement of Stock Purchase Contracts by a Holder of the related Common SPACES, the Pledged Treasury Securities underlying such Common SPACES shall be released from the Pledge as provided in the Pledge Agreement and the Holder shall be entitled to receive a number of newly issued or treasury shares of Common Stock adjusted in the same manner and at the same time as the Settlement Rate is adjusted (the “EARLY SETTLEMENT RATE”).

Upon the occurrence of a Cash Merger, a Holder of Stripped Common SPACES may effect Cash Merger Early Settlement of the Stock Purchase Contract underlying such Stripped Common SPACES pursuant to the terms of Section 5.04(b)(ii) of the Stock Purchase Contract Agreement. Upon Cash Merger Early Settlement of Stock Purchase Contracts by a Holder of the related Stripped Common SPACES, the Pledged Treasury Securities underlying such Stripped Common SPACES shall be released from the Pledge as provided in the Pledge Agreement.

Upon registration of transfer of this Stripped Common SPACES 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 Stock Purchase Contract Agent pursuant to the Stock Purchase Contract Agreement), under the terms of the Stock Purchase Contract Agreement and the Stock Purchase Contracts evidenced hereby and the transferor shall be released from the obligations under the Stock Purchase Contracts evidenced by this Stripped Common SPACES 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 Holder of this Stripped Common SPACES Certificate, by its acceptance hereof, authorizes the Stock Purchase Contract Agent to enter into and perform the related Stock Purchase Contracts forming part of the Stripped Common SPACES evidenced hereby on its behalf as its attorney-in-fact, expressly withholds any consent to the assumption (i.e., affirmance) of the Stock 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 Stock Purchase Contracts, consents to the provisions of the Stock Purchase Contract Agreement, authorizes the Stock Purchase Contract Agent to enter into and perform the Stock Purchase Contract Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and consents to the Pledge of the Treasury Securities underlying this Stripped Common SPACES Certificate pursuant to the Pledge Agreement. The Holder further covenants and agrees, that, to the extent and in the manner provided in the Stock Purchase Contract Agreement and the Pledge Agreement, but subject to the terms thereof, payments in respect to the aggregate principal amount of the Pledged Treasury Securities on the Stock Purchase Date shall be paid by the Collateral Agent to the Company in satisfaction of such Holder’s obligations under such Stock Purchase Contract and such Holder shall acquire no right, title or interest in such payments.

Subject to certain exceptions, the provisions of the Stock Purchase Contract Agreement may be amended with the consent of the Holders of a majority of the Stock Purchase Contracts.

The Stock Purchase Contracts shall for all purposes be governed by, and construed in accordance with, the laws of the State of New York.

Prior to due presentment of this Certificate for registration or transfer, the Company, the Stock Purchase Contract Agent and its Affiliates and any agent of the Company or the Stock Purchase Contract Agent may treat the Person in whose name this Stripped Common SPACES Certificate is registered as the owner of the Stripped Common SPACES evidenced hereby for the purpose of receiving payments of interest on the Treasury Securities, receiving payments of Contract Payments (subject to any applicable record date), performance of the Stock 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 Stock Purchase Contract Agent nor any such agent shall be affected by notice to the contrary.

The Stock 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.

A copy of the Stock Purchase Contract Agreement is available for inspection at the offices of the Stock Purchase Contract Agent.
