Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Agreement, they may, but need not, be consolidated and form one instrument. Section 1.04. Acts of Holders; Record Dates. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Agreement to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Purchase Contract Agent and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Agreement and (subject to Section 7.01) conclusive in favor of the 12 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 which the Purchase Contract Agent deems sufficient. (c) The ownership of Securities shall be proved by the Security Register. (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Certificate evidencing such Security 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 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 Securities 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 Securities. If any record date is set pursuant to this paragraph, the Holders of the Outstanding Stock Purchase Units and the Outstanding Treasury Stock Purchase Units, as the case may be, on such record date, and no other Holders, shall be entitled to take the relevant action with respect to the Stock Purchase Units or the Treasury Stock Purchase Units, as the case may be, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken prior to or on the applicable Expiration Date by Holders of the requisite number of Outstanding Securities 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 Securities on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Purchase Contract Agent in writing and to each Holder of Securities in the manner set forth in Section 1.06. With respect to any record date set pursuant to this Section, the Company may designate any date as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Purchase Contract Agent in writing, and to each Holder of Securities 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. 13 Section 1.05. Notices. 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 Purchase Contract Agent only upon receipt thereof: If to the Purchase Contract Agent: [ ] [ ] [ ] Telecopier No.: Attention: If to the Company: Black Hills Corporation Telecopier No.: Attention: with a copy to: [ ] [ ] If to the Collateral Agent: [ ] [ ] [ ] [ ] [ ] Telecopier No.: Attention: If to the Property Trustee: [ ] [ ] [ ] Telecopier No.: Attention: 14 If to the Indenture Trustee: [ ] [ ] [ ] [ ] [ ] Telecopier No.: Attention: Section 1.06. Notice to Holders; Waiver. 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 Purchase Contract Agent, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Purchase Contract Agent shall constitute a sufficient notification for every purpose hereunder. Section 1.07. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. Section 1.08. Successors and Assigns. All covenants and agreements in this Agreement by the Company and the Purchase Contract Agent shall bind their respective successors and assigns, whether so expressed or not. Section 1.09. Separability Clause. In case any provision in this Agreement or in the Securities 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. Section 1.10. Benefits of Agreement. 15 Nothing contained in this Agreement or in the Securities, 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 Securities evidenced by their Certificates by their acceptance of delivery of such Certificates. Section 1.11. Governing Law. This Agreement and the Securities shall be governed by, and construed in accordance with, the laws of the State of New York. Section 1.12. Legal Holidays. In any case where any Payment Date shall not be a Business Day (notwithstanding any other provision of this Agreement or the Securities), Purchase Contract Payments or other distributions shall not be paid on such date, but Purchase 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 no interest shall accrue or be payable by the Company or to any Holder for the period from and after any such Payment Date, except that, if such next succeeding Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day with the same force and effect as if made on such Payment Date. In any case where any Purchase Contract Settlement Date or Early Settlement Date shall not be a Business Day (notwithstanding any other provision of this Agreement or the Securities) Purchase Contracts shall not be performed and Early Settlement shall not be effected on such date, but Purchase Contracts shall be performed or Early Settlement effected, as applicable, on the next succeeding Business Day with the same force and effect as if made on such Purchase Contract Settlement Date or Early Settlement Date, as applicable. Section 1.13. Counterparts. 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. Section 1.14. Inspection of Agreement. A copy of this Agreement shall be available at all reasonable times during normal business hours at the Corporate Trust Office for inspection by any Holder or Beneficial Owner. Section 1.15. Appointment of Financial Institution as Agent for the Company. The Company may appoint a financial institution (which may be the Collateral Agent) to 16 act as its agent in performing its obligations and in accepting and enforcing performance of the obligations of the Purchase Contract Agent and the Holders, under this Agreement and the 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. ARTICLE 2 Certificate Forms Section 2.01. Forms of Certificates Generally. The Certificates (including the form of Purchase Contract forming part of each Security evidenced thereby) shall be in substantially the form set forth in Exhibit A hereto (in the case of Certificates evidencing Stock Purchase Units) or Exhibit B hereto (in the case of Certificates evidencing Treasury Stock Purchase Units), 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 Securities 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.

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 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 17 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 REGISTERED 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 Purchase Contract Agent's Certificate of Authentication. The form of the Purchase Contract Agent's certificate of authentication of the Securities shall be in substantially the form set forth on the form of the applicable Certificates. ARTICLE 3 The Securities Section 3.01. Amount; Form and Denominations. The aggregate number of Securities evidenced by Certificates authenticated, executed on behalf of the Holders and delivered hereunder is limited to ______________ [(_____________ if the over-allotment option granted in 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 Sections 3.04, 3.05, 3.10, 3.13, 3.14 or 8.05. The Certificates shall be issuable only in registered form and only in denominations of a single Stock Purchase Unit or Treasury Stock Purchase Unit and any integral multiple thereof. Section 3.02. Rights and Obligations Evidenced by the Certificates. Each Stock Purchase Units Certificate shall evidence the number of Stock Purchase Units specified therein, with each such Stock Purchase Unit representing (1) the ownership by the Holder thereof of a beneficial interest in a Note or the Applicable Ownership Interest of the Treasury Portfolio, as the case may be, subject to the Pledge of such Note or the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio, as the case may be, by such Holder pursuant to the Pledge Agreement, and (2) the rights and obligations of the Holder thereof and the Company under one Purchase Contract. The Purchase Contract Agent, as attorney-in-fact for, and on behalf of, the Holder of each Stock Purchase Unit shall pledge, pursuant to the Pledge Agreement, the Note or the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio, as the case may be, forming a part of such Stock Purchase Unit, to the Collateral Agent and grant to the Collateral Agent a security interest in the right, title and interest of such Holder in 18 such Note or the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio, as the case may be, for the benefit of the Company, to secure the obligation of the Holder under each Purchase Contract to purchase shares of Common Stock. Upon the formation of a Treasury Stock Purchase Unit pursuant to Section 3.13, each Treasury Stock Purchase Units Certificate shall evidence the number of Treasury Stock Purchase Units specified therein, with each such Treasury Stock Purchase Unit representing (1) the ownership by the Holder thereof of a [1/40] undivided beneficial interest in a Treasury Security with a principal amount equal to $1,000, subject to the Pledge of such Treasury Security by such Holder pursuant to the Pledge Agreement, and (2) the rights and obligations of the Holder thereof and the Company under one Purchase Contract. Prior to the purchase of shares of Common Stock under each Purchase Contract, such Purchase Contracts shall not entitle the Holder of a Security to any of the rights of a holder of shares of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as a shareholder in respect of the meetings of shareholders or for the election of directors of the Company or for any other matter, or any other rights whatsoever as a shareholder of the Company. Section 3.03. Execution, Authentication, Delivery and Dating. Subject to the provisions of Sections 3.13 and 3.14 hereof, upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Certificates executed by the Company to the Purchase Contract Agent for authentication, execution on behalf of the Holders and delivery, together with its Issuer Order for authentication of such Certificates, and the Purchase Contract Agent in accordance with such Issuer Order shall authenticate, execute on behalf of the Holders and deliver such Certificates. The Certificates shall be executed on behalf of the Company by its Chairman of the Board, its President 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 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 signatory of the Purchase Contract Agent, as such Holder's attorney-in-fact. Such signature by an authorized signatory of the Purchase Contract Agent shall be conclusive evidence that the Holder of such Certificate has entered into the Purchase Contracts evidenced by such Certificate. Each Certificate shall be dated the date of its authentication. 19 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 signatory of the Purchase Contract Agent by manual signature, and such certificate upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. Section 3.04. Temporary Certificates. Pending the preparation of definitive Certificates, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holders, and deliver, in lieu of such definitive Certificates, temporary Certificates which are in substantially the form set forth in Exhibit A or Exhibit B hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be required by the rules of any securities exchange on which the Stock Purchase Units or Treasury Stock Purchase Units, 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 Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, one or more definitive Certificates of like tenor and denominations and evidencing a like number of Securities 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 Securities, evidenced thereby as definitive Certificates. Section 3.05. Registration; Registration of Transfer and Exchange. The 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 Purchase Contract Agent shall provide for the registration of Certificates and of transfers of Certificates (the Purchase Contract Agent, in such capacity, the "Security Registrar"). The Security Registrar shall record separately the registration and transfer of the Certificates evidencing Stock Purchase Units and Treasury Stock Purchase Units. Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the designated transferee or transferees, and deliver, in the name of the designated transferee or transferees, one or more new Certificates of any authorized denominations, like tenor, and evidencing a like number of Stock Purchase 20 Units or Treasury Stock Purchase Units, as the case may be. At the option of the Holder, Certificates may be exchanged for other Certificates, of any authorized denominations and evidencing a like number of Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, upon surrender of the Certificates to be exchanged at the Corporate Trust Office. Whenever any Certificates are so surrendered for exchange, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver the Certificates which the Holder making the exchange is entitled to receive. All Certificates issued upon any registration of transfer or exchange of a Certificate shall evidence the ownership of the same number of Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, and be entitled to the same benefits and subject to the same obligations, under this Agreement as the Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, evidenced by the Certificate surrendered upon such registration of transfer or exchange. Every Certificate presented or surrendered for registration of transfer or exchange shall (if so required by the Purchase Contract Agent) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Purchase Contract Agent duly executed, by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of a Certificate, but the Company and the Purchase Contract Agent may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Certificates, other than any exchanges pursuant to Sections 3.06 and 8.05 not involving any transfer. Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to authenticate, execute on behalf of the Holder and deliver any Certificate in exchange for any other Certificate presented or surrendered for registration of transfer or for exchange on or after the Business Day immediately preceding the earliest of any Early Settlement Date for such Certificate, the Purchase Contract Settlement Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Purchase Contract Agent shall: (i) if the Purchase Contract Settlement Date or an Early Settlement Date with respect to such other Certificate has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Securities evidenced by such other Certificate; or (ii) if a Cash Settlement or an Early Settlement Date with respect to such other Certificate shall have occurred, or if a Termination Event shall have occurred prior to the Purchase Contract Settlement Date, transfer the Notes, the Treasury Securities, or the 21 appropriate Applicable Ownership Interest of the Treasury Portfolio, 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 Five hereof. Section 3.06. Book-Entry Interests. The Certificates, on original issuance, will be issued in the form of one or more fully registered Global Certificates, to be delivered to the Depositary or its custodian by, or on behalf of, the Company. 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 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: (i) the provisions of this Section 3.06 shall be in full force and effect; (ii) the Company shall be entitled to deal with the Depositary for all purposes of this Agreement (including making Purchase Contract Payments and receiving approvals, votes or consents hereunder) as the Holder of the Securities and the sole holder of the Global Certificates and shall have no obligation to the Beneficial Owners; (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. Section 3.07. Notices to Holders. Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company's agent shall give such notices and communications to the Holders and, with respect to any Securities 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. Section 3.08. Appointment of Successor Depositary. If the Depositary elects to discontinue its services as securities depositary with respect to the Securities, the Company may, in its sole discretion, appoint a successor Depositary with respect to the Securities. Section 3.09. Definitive Certificates. 22 If: (i) the Depositary elects to discontinue its services as securities depositary with respect to the Securities and a successor Depositary is not appointed pursuant to Section 3.08 within 90 days after such discontinuance; or (ii) the Company elects, after consultation with the Purchase Contract Agent, to terminate the book-entry system for the Securities, then (x) definitive Certificates shall be prepared by the Company with respect to such Securities and delivered to the Purchase Contract Agent and (y) upon surrender of the Global Certificates representing the Securities 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 shall not be liable for any delay in delivery of such instructions and may conclusively rely on and shall be protected in relying on, such instructions. Each definitive Certificate so delivered shall evidence Securities of the same kind and tenor as the Global Certificate so surrendered in respect thereof. Section 3.10. Mutilated, Destroyed, Lost and Stolen Certificates. If any mutilated Certificate is surrendered to the Purchase Contract Agent, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver in exchange therefor, a new Certificate, evidencing the same number of Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding. If there shall be delivered to the Company and the Purchase Contract Agent (i) evidence to their satisfaction of the destruction, loss or theft of any Certificate, and (ii) such security or indemnity as may be required by them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Purchase Contract Agent that such Certificate has been acquired by a protected purchaser, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Certificate, a new Certificate, evidencing the same number of Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding. Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to authenticate, execute on behalf of the Holder, and deliver to the Holder, a Certificate on or after the Business Day immediately preceding the earliest of any Early Settlement Date for such lost or mutilated Certificate, the Purchase Contract Settlement Date or the Termination Date. In lieu of delivery of a new Certificate, upon satisfaction of the applicable conditions specified above in this Section and receipt of appropriate registration or transfer instructions from such Holder, the Purchase Contract Agent shall: 23 (i) if the Purchase Contract Settlement Date or an Early Settlement Date with respect to such lost or mutilated Certificate has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Securities evidenced by such Certificate; or (ii) if a Cash Settlement with respect to such lost or mutilated Certificate shall have occurred or if a Termination Event shall have occurred prior to the Purchase Contract Settlement Date, transfer the Notes, the Treasury Securities or the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio, 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 Five hereof. Upon the issuance of any new Certificate under this Section, the Company and the Purchase Contract Agent may require the payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Purchase Contract Agent) connected therewith. Every new Certificate issued pursuant to this Section in lieu of any destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Security evidenced thereby, whether or not the destroyed, lost or stolen Certificate (and the Securities evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and proportionately with any and all other Certificates delivered hereunder. The provisions of this Section are exclusive and shall preclude, to the extent lawful, all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. Section 3.11. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Company and the Purchase Contract Agent, and any agent of the Company or the Purchase Contract Agent, may treat the Person in whose name such Certificate is registered as the owner of the Security evidenced thereby, for the purpose of receiving distributions on the Treasury Securities, the Notes, or on the maturing quarterly interest strips of the Treasury Portfolio, as applicable, receiving Purchase Contract Payments, performance of the Purchase Contracts and for all other purposes whatsoever, whether or not any distributions on the Treasury Securities, the Notes, or Treasury Portfolio, as applicable, or Purchase Contract Payments payable on the Purchase Contracts, each constituting a part of the Security evidenced thereby shall be overdue and notwithstanding any notice to the contrary, and neither the Company nor the Purchase Contract Agent, nor any agent of the Company or the Purchase Contract Agent, shall be affected by notice to the contrary. Notwithstanding the foregoing, with respect to any Global Certificate, nothing contained 24 herein shall prevent the Company, the Purchase Contract Agent or any agent of the Company or the Purchase Contract Agent, from giving effect to any written certification, proxy or other authorization furnished by 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. Section 3.12. Cancellation. All Certificates surrendered for delivery of shares of Common Stock on or after the Purchase Contract Settlement Date, upon the transfer of Notes, the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of that term) of the Treasury Portfolio or Treasury Securities, as the case may be, after the occurrence of a Termination Event or pursuant to an Early Settlement, or upon the registration of transfer or exchange of a Security, or a Collateral Substitution or the reestablishment of Stock Purchase Units shall, if surrendered to any Person other than the Purchase Contract Agent, be delivered to the Purchase Contract Agent and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the Purchase Contract Agent for cancellation any Certificates previously authenticated, executed and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the Purchase Contract Agent. No Certificates shall be authenticated, executed on behalf of the Holder and delivered in lieu of or in exchange for any Certificates cancelled as provided in this Section, except as expressly permitted by this Agreement. All cancelled Certificates held by the Purchase Contract Agent shall be disposed of 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 Purchase Contract Agent cancelled or for cancellation. Section 3.13. Creation of Treasury Stock Purchase Units by Substitution of Treasury Securities. Subject to the conditions set forth in this Agreement, a Holder may separate the Notes, as applicable, from the related Purchase Contracts in respect of such Holder's Stock Purchase Units by substituting for such Notes, as applicable, Treasury Securities in an aggregate principal amount equal to the aggregate principal amount of such Notes, as applicable (a "Collateral Substitution"), at any time from and after the date of this Agreement and prior to or on the seventh Business Day immediately preceding the Purchase Contract Settlement Date. To effect such substitution, the Holder must: (1) deposit with the Securities Intermediary Treasury Securities having an aggregate principal amount equal to the aggregate principal amount of the Notes comprising part of such Stock Purchase Units, as the case may be; and (2) transfer the related Stock Purchase Units to the Purchase Contract Agent 25 accompanied by a notice to the Purchase Contract Agent, substantially in the form of Exhibit C hereto, (i) stating that the Holder has transferred the relevant amount of Treasury Securities to the Securities Intermediary and (ii) requesting that the Purchase Contract Agent instruct the Collateral Agent to release the Notes, as the case may be, underlying such Stock Purchase Units, whereupon the 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 Notes, as the case may be, from the Pledge, free and clear of the Company's security interest therein, and the transfer of such Notes, as the case may be, to the Purchase Contract Agent on behalf of the Holder. Upon receipt thereof, the Purchase Contract Agent shall promptly: (i) cancel the related Stock Purchase Units; (ii) transfer the Notes, as the case may be, to the Holder; and (iii) authenticate, execute on behalf of such Holder and deliver a Treasury Stock Purchase Units Certificate executed by the Company in accordance with Section 3.03 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Stock Purchase Units. Holders who elect to separate the Notes, as the case may be, from the related Purchase Contracts and to substitute Treasury Securities for such Notes, as the case may be, shall be responsible for any fees or expenses payable to the Collateral Agent for its services as Collateral Agent in respect of the substitution, and the Company shall not be responsible for any such fees or expenses. Holders may make Collateral Substitutions only in integral multiples of 40 Stock Purchase Units. If a Tax Event Redemption has occurred, Holders may no longer convert their Stock Purchase Units into Treasury Stock Purchase Units. In the event a Holder making a Collateral Substitution pursuant to this Section 3.13 fails to effect a book-entry transfer of the Stock Purchase Units or fails to deliver Stock Purchase Units Certificates to the Purchase Contract Agent after depositing Treasury Securities with the Collateral Agent, any distributions on the Notes constituting a part of such Stock Purchase Units, as the case may be, shall be held in the name of the Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until such Stock Purchase Units are so transferred or the Stock Purchase Units Certificate is so delivered, as the case may be, or, such Holder provides evidence satisfactory to the Company and the Purchase Contract Agent that such Stock Purchase Units Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Purchase Contract Agent and the Company. 26 Except as described in this Section 3.13 or in connection with a Cash Settlement, for so long as the Purchase Contract underlying a Stock Purchase Unit remains in effect, such Stock Purchase Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder in respect of the Notes, as the case may be, and the Purchase Contract comprising such Stock Purchase Unit may be acquired, and may be transferred and exchanged, only as a Stock Purchase Unit. Section 3.14. Reestablishment of Stock Purchase Units. Subject to the conditions set forth in this Agreement, a Holder of Treasury Stock Purchase Units may reestablish Stock Purchase Units at any time (i) prior to or on the seventh Business Day immediately preceding the Purchase Contract Settlement Date, by: (1) depositing with the Securities Intermediary Notes, as the case may be, having an aggregate principal amount equal to the aggregate principal amount at maturity of the Treasury Securities comprising part of the Treasury Stock Purchase Units; and (2) transferring the related Treasury Stock Purchase Units to the Purchase Contract Agent accompanied by a notice to the Purchase Contract Agent, substantially in the form of Exhibit C hereto, (i) stating that the Holder has transferred the relevant amount of Notes, as the case may be, to the Securities Intermediary and (ii) requesting that the Purchase Contract Agent instruct the Collateral Agent to release the Treasury Securities underlying such Treasury Stock Purchase Units, whereupon the Purchase Contract Agent shall promptly provide an instruction to such effect to the Collateral Agent, substantially in the form of Exhibit C to the Pledge Agreement. Upon receipt of the Notes, as the case may be, 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 Treasury Securities having a corresponding aggregate principal amount at maturity from the Pledge, free and clear of the Company's security interest therein, and the transfer to the Purchase Contract Agent on behalf of the Holder. Upon receipt thereof, the Purchase Contract Agent shall promptly: (i) cancel the related Treasury Stock Purchase Units; (ii) transfer the Treasury Securities to the Holder; and (iii) authenticate, execute on behalf of such Holder and deliver a Stock Purchase Units Certificate executed by the Company in accordance with Section 3.03 evidencing the same number of Purchase Contracts as were evidenced by the cancelled Treasury Stock Purchase Units. 27 Holders who elect to reestablish Stock Purchase Units shall be responsible for any fees or expenses payable to the Collateral Agent for its services as Collateral Agent in respect of the reestablishment, and the Company shall not be responsible for any such fees or expenses. Holders of Treasury Stock Purchase Units may only reestablish Stock Purchase Units in integral multiples of 40 Treasury Stock Purchase Units. If a Tax Event Redemption has occurred, Holders may no longer convert their Treasury Stock Purchase Units into Stock Purchase Units. Except as provided in this Section 3.14 or in connection with a Cash Settlement, for so long as the Purchase Contract underlying a Treasury Stock Purchase Unit remains in effect, such Treasury Stock Purchase Unit shall not be separable into its constituent parts and the rights and obligations of the Holder of such Treasury Stock Purchase Unit in respect of the [1/40] of a Treasury Security and the Purchase Contract comprising such Treasury Stock Purchase Unit may be acquired, and may be transferred and exchanged, only as a Treasury Stock Purchase Unit. Section 3.15. Transfer of Collateral upon Occurrence of Termination Event. Upon the occurrence of a Termination Event and the transfer to the Purchase Contract Agent of the Notes, the appropriate Applicable Ownership Interest of the Treasury Portfolio or the Treasury Securities, as the case may be, underlying the Stock Purchase Units and the Treasury Stock Purchase Units, as the case may be, pursuant to the terms of the Pledge Agreement, the Purchase Contract Agent shall request transfer instructions with respect to such Notes, the appropriate Applicable Ownership Interest of the Treasury Portfolio 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 Stock Purchase Units or the Treasury Stock Purchase Units or delivery of a Stock Purchase Units Certificate or Treasury Stock Purchase Units Certificate to the Purchase Contract Agent with such transfer instructions, the Purchase Contract Agent shall transfer the Notes, the appropriate Applicable Ownership Interest of the Treasury Portfolio or Treasury Securities, as the case may be, underlying such Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, to such Holder by book-entry transfer, or other appropriate procedures, in accordance with such instructions. In the event a Holder of Stock Purchase Units or Treasury Stock Purchase Units fails to effect such transfer or delivery, the Notes, the appropriate Applicable Ownership Interest of the Treasury Portfolio or Treasury Securities, as the case may be, underlying such Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, and any distributions thereon, shall be held in the name of the Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until the earlier to occur of: (i) the transfer of such Stock Purchase Units or Treasury Stock Purchase Units or surrender of the Stock Purchase Units Certificate or Treasury Stock Purchase Units Certificate or receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such Stock Purchase Units Certificate or Treasury Stock Purchase Units Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Purchase Contract Agent and the Company; and 28 (ii) the expiration of the time period specified in the abandoned property laws of the relevant State. Section 3.16. No Consent to Assumption. Each Holder of a Security, by acceptance thereof, shall be deemed expressly to have withheld any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its trustee, receiver, liquidator or a person or entity performing similar functions in the event that the Company becomes the debtor under the Bankruptcy Code or subject to other similar state or Federal law providing for reorganization or liquidation. ARTICLE 4 The Notes and Applicable Ownership Interest of the Treasury Portfolio Section 4.01. Interest Payments; Rights to Interest Payments Preserved. Any distribution on any Note or on the appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case may be, which is paid on any Payment Date shall, subject to receipt thereof by the Purchase Contract Agent from the Collateral Agent as provided by the terms of the Pledge Agreement, be paid to the Person in whose name the Stock Purchase Units Certificate (or one or more Predecessor Stock Purchase Units Certificates) of which such Note or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case may be, is registered at the close of business on the Record Date for such Payment Date. Any such distribution shall be subject to deferral at the option of the Company in accordance with the Indenture and the Declaration. Each Stock Purchase Units Certificate evidencing Notes or the appropriate Applicable Ownership Interest of the Treasury Portfolio delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of any other Stock Purchase Units Certificate shall carry the right to distributions accrued and unpaid, and to accrue distributions interest, which were carried by the Notes or the appropriate Applicable Ownership Interest of the Treasury Portfolio underlying such other Stock Purchase Units Certificate. In the case of any Stock Purchase Units with respect to which Cash Settlement of the underlying Purchase Contract is properly effected pursuant to Section 5.02 hereof, or with respect to which Early Settlement of the underlying Purchase Contract is properly effected pursuant to Section 5.04 hereof, or with respect to which a Collateral Substitution is effected, 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 Notes or on the appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case may be, underlying such Stock Purchase Unit otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Cash Settlement or 29 Early Settlement or Collateral Substitution, and such distributions shall, subject to receipt thereof by the Purchase Contract Agent, be payable to the Person in whose name the Stock Purchase Units Certificate (or one or more Predecessor Stock Purchase Units Certificates) was registered at the close of business on the Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Stock Purchase Unit with respect to which Cash Settlement or Early Settlement of the underlying Purchase Contract is properly effected, or with respect to which a Collateral Substitution has been effected, distributions on the related Notes or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case may be, that would otherwise be payable after the Purchase Contract Settlement Date, 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 Stock Purchase Units; provided, however, that to the extent that such Holder continues to hold separated Notes that formerly comprised a part of such Holder's Stock Purchase Unit, such Holder shall be entitled to receive distributions on such separated Notes. Not later than 15 calendar days nor more than 30 calendar days prior to the Remarketing Date, the Company shall request the Depositary to notify the Beneficial Owners or Depositary Participants holding Securities of the procedures to be followed by Holders of Securities who intend to effect a Cash Settlement. Section 4.02. Notice and Voting. Under the terms of the Pledge Agreement, the Purchase Contract Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged Notes, 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 Notes are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of Notes, the Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage pre-paid, to the Holders of Stock Purchase Units a notice: (i) containing such information as is contained in the notice or solicitation; (ii) stating that each Holder on the record date set by the Purchase Contract Agent therefor (which, to the extent possible, shall be the same date as the record date for determining the holders of Notes, as the case may be, entitled to vote) shall be entitled to instruct the Purchase Contract Agent as to the exercise of the voting rights pertaining to such Notes underlying their Stock Purchase Units; and (iii) stating the manner in which such instructions may be given. Upon the written request of the Holders of Stock Purchase Units on such record date received by the Purchase Contract Agent at least six days prior to such meeting, the Purchase Contract Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum number of Notes, 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 Stock Purchase Unit, the Purchase Contract Agent shall abstain from voting the 30 Notes underlying such Stock Purchase Unit. The Company hereby agrees, if applicable, to solicit Holders of Stock Purchase Units to timely instruct the Purchase Contract Agent in order to enable the Purchase Contract Agent to vote such Notes. Section 4.03. Tax Event Redemption. (a) Upon the occurrence of a Tax Event Redemption prior to the Purchase Contract Settlement Date, an amount equal to the Redemption Amount, plus any accumulated and unpaid distributions or accrued and unpaid interest, as the case may be, payable on the Tax Event Redemption Date with respect to the principal amount of the Notes shall be deposited in the Collateral Account in exchange for the Pledged Notes. Thereafter, pursuant to the terms of the Pledge Agreement, the Collateral Agent shall cause the Securities Intermediary to apply an amount equal to the Redemption Amount of such funds to purchase on behalf of the Holders of Stock Purchase Units the Treasury Portfolio and promptly remit the remaining portion of such funds to the Purchase Contract Agent for payment to the Holders of such Stock Purchase Units. (b) The Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio will be substituted as Collateral for the Pledged Notes, as the case may be, and will be held by the Collateral Agent in accordance with the terms of the Pledge Agreement to secure the obligation of each Holder of Stock Purchase Unit to purchase the Common Stock of the Company under the Purchase Contract constituting a part of such Stock Purchase Unit. Following the occurrence of a Tax Event Redemption prior to the Purchase Contract Settlement Date, the Holders of Stock Purchase Units and the Collateral Agent shall have such security interest rights and obligations with respect to the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio as the Holders of Stock Purchase Units and the Collateral Agent had in respect of the Notes, as the case may be, subject to the Pledge thereof as provided in the Pledge Agreement, and any reference herein to the Notes shall be deemed to be reference to such Treasury Portfolio. The Company may cause to be made in any Stock Purchase Units Certificates thereafter to be issued such change in phraseology and form (but not in substance) as may be appropriate to reflect the substitution of the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio for Notes as Collateral. ARTICLE 5 The Purchase Contracts Section 5.01. Purchase of Shares of Common Stock. (a) Each Purchase Contract shall obligate the Holder of the related Security to purchase, and the Company to sell, on the Purchase Contract Settlement Date at a price equal to the Stated Amount (the "Purchase Price"), a number of shares of Common Stock (subject to Section 5.09) equal to the Settlement Rate unless an Early Settlement has occurred in accordance with Section 5.04 hereof or, prior to or on the Purchase Contract Settlement Date, there shall have occurred a 31 Termination Event with respect to the Security of which such Purchase Contract is a part. The "Settlement Rate" is equal to: (i) if the Applicable Market Value (as defined below) is greater than or equal to $______ (the "Threshold Appreciation Price"), ________ share of Common Stock per Purchase Contract; and (ii) if the Applicable Market Value is less than the Threshold Appreciation Price but greater than $_______ (the "Reference Price"), the number of shares of Common Stock per Purchase Contract having a value, based on the Applicable Market Value, equal to the Stated Amount; and (iii) if the Applicable Market Value is less than or equal to the Reference Price, _______ share of Common Stock per Purchase Contract, in each case subject to adjustment as provided in Section 5.04 (and in each case rounded upward or downward to the nearest 1/10,000th of a share). 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 the Purchase Contract Settlement Date. The "Closing Price" per share of Common Stock on any date of determination means: (i) the closing sale price as of the 4:15 p.m. 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; (ii) if the Common Stock is not listed for trading on the NYSE on any such date, the closing sale price per share as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is so listed; (iii) if the Common Stock is not so listed on a United States national or regional securities exchange, the closing sale price per share as reported by The Nasdaq National Market; (iv) if the Common Stock is not so reported, 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 such bid price is not available, the average of the mid-point of the last bid and ask prices of the Common Stock on such date from at least three nationally recognized independent investment banking firms retained for this purpose by the Company. 32 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 Stock Purchase Unit or a Treasury Stock Purchase Unit, by its acceptance thereof: (i) irrevocably authorizes the Purchase Contract Agent to enter into and perform the related Purchase Contract on its behalf as its attorney-in- fact (including the execution of Certificates on behalf of such Holder); (ii) agrees to be bound by the terms and provisions thereof; iii) covenants and agrees to perform its obligations under such Purchase Contract; (iv) consents to the provisions hereof; (v) irrevocably authorizes the Purchase Contract Agent to enter into and perform this Agreement and the Pledge Agreement on its behalf as its attorney-in-fact; and (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 Notes, the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio or the Treasury Securities pursuant to the Pledge Agreement, provided that upon a Termination Event, the rights of the Holder of such Security under the Purchase Contract may be enforced without regard to any other rights or obligations. Each Holder of a Stock Purchase Unit or a Treasury Stock Purchase Unit, by its acceptance thereof, further covenants and agrees, that to the extent and in the manner provided in Section 5.02 and the Pledge Agreement, but subject to the terms thereof, payments in respect of the Notes or the proceeds from the Treasury Securities or the Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio at maturity on the Purchase Contract Settlement Date, as the case may be, shall be paid by the Collateral Agent to the Company in satisfaction of such Holder's obligations under such Purchase Contract and such Holder shall acquire no right, title or interest in such payments. Upon registration of transfer of a Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee) by the terms of this Agreement, the Purchase Contracts underlying such Certificate, the Declaration and the Pledge Agreement and the transferor shall be released from the obligations under this Agreement, the Purchase Contracts underlying the Certificate so transferred and the Pledge Agreement. The Company 33 covenants and agrees, and each Holder of a Certificate, by its acceptance thereof, likewise covenants and agrees, to be bound by the provisions of this paragraph. Section 5.02. Payment of Purchase Price. (a) (i) Unless a Tax Event Redemption has occurred or a Holder of a Stock Purchase Unit effects an Early Settlement of the underlying Purchase Contract in the manner described in Section 5.04, each Holder who intends to pay in cash to satisfy such Holder's obligations under the Purchase Contract on the Purchase Contract Settlement Date shall notify the Purchase Contract Agent by use of a notice in substantially the form of Exhibit E hereto of his intention to pay in cash ("Cash Settlement") the Purchase Price for the shares of Common Stock to be purchased pursuant to the related Purchase Contract. Such notice shall be given prior to 5:00 p.m. (New York City time) on the seventh Business Day immediately preceding the Purchase Contract Settlement Date. Prior to 11:00 a.m. (New York City time) on the next succeeding Business Day, the Purchase Contract Agent shall notify the Collateral Agent and the Property Trustee or the Indenture Trustee, as the case may be, of the receipt of such notices from Holders intending to make a Cash Settlement. (ii) A Holder of a Stock Purchase Unit who has so notified the Purchase Contract Agent of his intention to effect a Cash Settlement in accordance with paragraph 5.02(a)(i) above shall pay the Purchase Price to the Securities Intermediary for deposit in the Collateral Account prior to 11:00 a.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, in lawful money of the United States by certified or cashiers' check or wire transfer, in each case in immediately available funds payable to or upon the order of the Securities Intermediary. Any cash received by the Collateral Agent shall be invested promptly by the Securities Intermediary in Permitted Investments and paid to the Company on the Purchase Contract Settlement Date in settlement of the Purchase Contracts in accordance with the terms of this Agreement and the Pledge Agreement. Any funds received by the Securities Intermediary in respect of the investment earnings from such Permitted Investments in excess of the Purchase Price for the shares of Common Stock to be purchased by such Holder shall be distributed to the Purchase Contract Agent when received for payment to the Holder. (iii) If a Holder of a Stock Purchase Unit fails to notify the Purchase Contract Agent of his intention to make a Cash Settlement in accordance with paragraph 5.02(a)(i) above, or does notify the Purchase Contract Agent as provided in paragraph 5.02(a)(i) above of his intention to pay the Purchase Price in cash, but fails to make such payment as required by paragraph 5.02(a)(ii) above, such Holder shall be deemed to have consented to the disposition of the Pledged Notes pursuant to the Remarketing as described in paragraph 5.02(b) below. (iv) Promptly after 11:00 a.m. (New York City time) on the fifth Business Day preceding the Purchase Contract Settlement Date, the Purchase Contract Agent, based on notices received by the Purchase Contract Agent pursuant to Section 5.02(a) hereof and notice from the Securities Intermediary regarding cash received 34 by it prior to such time, shall notify the Collateral Agent and the Property Trustee or the Indenture Trustee, as applicable of the aggregate number of Notes to be tendered for purchase in the Remarketing in a notice substantially in the form of Exhibit F hereto. (b) (i) In order to dispose of the Notes, Stock Purchase Units Holders who have not notified the Purchase Contract Agent of their intention to effect a Cash Settlement as provided in paragraph 5.02(a)(i) above, or who have so notified the Purchase Contract Agent but failed to make such payment as required by paragraph 5.02(a)(ii) above, the Company shall engage _____________________, as Remarketing Agent (the "Remarketing Agent"), pursuant to the Remarketing Agreement (and subject to removal as provided in the Remarketing Agreement) to sell such Notes. In order to facilitate the Remarketing, the Purchase Contract Agent, based on the notices specified in Section 5.02(a)(iv), shall notify the Remarketing Agent, promptly after 11:00 a.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, of the aggregate number of Notes that are part of Stock Purchase Units to be remarketed. Concurrently, the Collateral Agent, pursuant to the terms of the Pledge Agreement, shall cause such Notes to be presented to the Remarketing Agent for Remarketing. Upon receipt of such notice from the Purchase Contract Agent and such Notes, the Remarketing Agent shall, on the third Business Day immediately preceding the Purchase Contract Settlement Date, use reasonable efforts to remarket such Notes on such date at a price equal to [ ]% of the Stated Amount ($[ ]) per Note, as provided in the Remarketing Agreement. The proceeds from the Remarketing shall be invested by the Collateral Agent in Permitted Investments, in accordance with the Pledge Agreement, and then applied to satisfy in full such Stock Purchase Units Holders' obligations to pay the Purchase Price for the shares of Common Stock under the related Purchase Contracts on the Purchase Contract Settlement Date. In addition, [$ ] per Note of the proceeds shall automatically be remitted to the Remarketing Agent for services rendered in connection with the Remarketing (the "Remarketing Fee"). If, in spite of using its reasonable efforts, the Remarketing Agent cannot remarket the related Notes of such Holders of Stock Purchase Units at a price equal to [ ]% of the Stated Amount ($[ ]), then the Remarketing Agent shall increase the interest rate on the Notes so that the market value of such Notes will equal ($[ ]). If the Remarketing Agent determines that it will be able to remarket the related Notes of such Holders of Stock Purchase Units at a price in excess of [ ]% of the Stated Amount ($[ ]), then the Remarketing Agent shall decrease the interest rate on the Notes so that the market value of such Notes will be equal to [$ ]. If the Remarketing Agent cannot Remarket the Notes, as the case may be, after such increase or decrease, the Remarketing shall be deemed to have failed (a "Failed Remarketing"), an event of default shall be deemed to have occurred under this Agreement and the Pledge Agreement and in accordance with the terms of the Pledge Agreement, the Collateral Agent, for the benefit of the Company, shall exercise its rights as a secured party with respect to such Notes, including those actions specified in paragraph 5.02(c) below; provided, that if upon a Failed Remarketing the Collateral Agent exercises such rights for the benefit of the Company with respect to such Notes, any accrued and unpaid distributions on such Notes and any accrued and unpaid Purchase Contract Payments (including any deferred Purchase Contract Payments) shall become payable by 35 the Company to the Purchase Contract Agent for payment to the Beneficial Owner of the Stock Purchase Units to which such Notes relate. The Company shall cause a notice of such Failed Remarketing to be published on the second Business Day immediately preceding the Purchase Contract Settlement Date in a daily newspaper in the English language of general circulation in the City of New York, which is expected to be The Wall Street Journal, and on Bloomberg News. (c) With respect to any Notes which are subject to a Failed Remarketing, 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 paragraph 5.02(g) below, shall, in full satisfaction of the Holders' obligations under the Purchase Contracts among other things, (i) retain the Notes, (ii) sell the Notes in one or more public or private sales or (iii) take, or choose not to take, any other action with respect to the Notes, which in every case specified in (i), (ii) and (iii) shall constitute payment in full for the aggregate Purchase Price for the shares of Common Stock to be purchased under the Purchase Contracts. (d) Unless a Holder of a Treasury Stock Purchase Unit or Stock Purchase Unit (if a Tax Event Redemption has occurred) effects an Early Settlement of the underlying Purchase Contract through the early delivery of cash to the Purchase Contract Agent in the manner described in Section 5.04, each Holder of a Treasury Stock Purchase Unit or Stock Purchase Unit (if a Tax Event Redemption has occurred) who intends to pay in cash shall notify the Purchase Contract Agent by use of a notice in substantially the form of Exhibit E hereto of his intention to pay in cash the Purchase Price for the shares of Common Stock to be purchased pursuant to the related Purchase Contract. Such notice shall be given prior to 5:00 p.m. (New York City time) on the second Business Day immediately preceding the Purchase Contract Settlement Date. Prior to 11:00 a.m. (New York City time) on the next succeeding Business Day, the Purchase Contract Agent shall notify the Collateral Agent of the receipt of such notices from such Holders intending to make a Cash Settlement. Treasury Stock Purchase Unit holders may make Cash Settlements only in integral multiples of 40 Treasury Stock Purchase Units. (ii) A Holder of a Treasury Stock Purchase Unit or Stock Purchase Units (if a Tax Event Redemption has occurred) who has so notified the Purchase Contract Agent of his intention to make a Cash Settlement in accordance with paragraph 5.02(d)(i) above shall pay the Purchase Price to the Securities Intermediary for deposit in the Collateral Account prior to 11:00 a.m. (New York City time) on the Business Day immediately preceding the Purchase Contract Settlement Date, in lawful money of the United States by certified or cashiers' check or wire transfer, in each case in immediately available funds payable to or upon the order of the Securities Intermediary. Any cash received by the Collateral Agent shall be invested promptly by the Securities Intermediary in Permitted Investments and paid to the Company on the Purchase Contract Settlement Date in settlement of the Purchase Contract in accordance with the terms of this Agreement and the Pledge Agreement. Any funds received by the Securities Intermediary in respect of the investment earnings from the investment in such Permitted Investments in excess of the Purchase Price for the shares of Common Stock to be purchased by such Holder shall be 36 distributed to the Purchase Contract Agent when received for payment to the Holder. (iii) If a Holder of a Treasury Stock Purchase Unit or Holder of a Stock Purchase Unit (if a Tax Event Redemption has occurred) fails to notify the Purchase Contract Agent of his intention to make a Cash Settlement in accordance with paragraph 5.02(d)(i) above, or does notify the Purchase Contract Agent as provided in paragraph 5.02(d)(i) above of his intention to pay the Purchase Price in cash, but fails to make such payment as required by paragraph 5.02(d)(ii) above, then upon the maturity of the Pledged Treasury Securities or the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio held by the Securities Intermediary on the Business Day immediately preceding the Purchase Contract Settlement Date, the principal amount of the Treasury Securities or the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio received by the Securities Intermediary shall be invested promptly in Permitted Investments. On the Purchase Contract Settlement Date, an amount equal to the Purchase Price shall be remitted to the Company as payment thereof without receiving any instructions from the Holder. In the event the sum of the proceeds from the related Pledged Treasury Securities or the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio and the investment earnings earned from such investments is in excess of the aggregate Purchase Price of the Purchase Contracts being settled thereby, the Collateral Agent shall cause the Securities Intermediary to distribute such excess to the Purchase Contract Agent for the benefit of the Holder of the related Treasury Stock Purchase Unit or Stock Purchase Unit when received. (iv) A holder of a Note that is no longer part of a Stock Purchase Unit may elect to have such Note, as the case may be, remarketed. A holder making such an election must notify the Indenture Trustee prior to 11:00 a.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, of the aggregate number of Notes, as the case may be, that are not part of Stock Purchase Units to be remarketed. Any such notice will be irrevocable and may not be conditioned upon the level at which the Reset Rate is established in the Remarketing. Concurrently, the Property Trustee or the Indenture Trustee, as the case may be, shall cause such Notes, as the case may be, to be presented to the Remarketing Agent for Remarketing. (e) Any distribution to Holders of any payments described above shall be payable at the office of the Purchase Contract Agent in New York City maintained for that purpose or, at the option of the Holder, by check mailed to the address of the Person entitled thereto at such address as it appears on the Security Register. (f) Upon Cash Settlement of any Purchase Contract: 37 (i) the Collateral Agent will in accordance with the terms of the Pledge Agreement cause the Pledged Notes, the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio or the Pledged Treasury Securities, as the case may be, underlying the relevant Security to be released from the Pledge, free and clear of any security interest of the Company, and transferred to the Purchase Contract Agent for delivery to the Holder thereof or its designee as soon as practicable; and (ii) subject to the receipt thereof, the Purchase Contract Agent shall, by book-entry transfer or other appropriate procedures, in accordance with written instructions provided by the Holder thereof, transfer such Notes, or the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio or such Treasury Securities, as the case may be (or, if no such instructions are given to the Purchase Contract Agent by the Holder, the Purchase Contract Agent shall hold such Notes, or the appropriate Applicable Ownership Interest (as specified in clause (A) of the definition of such term) of the Treasury Portfolio or such Treasury Securities, as the case may be, and any interest payment thereon, in the name of the Purchase Contract Agent or its nominee in trust for the benefit of such Holder until the expiration of the time period specified in the abandoned property laws of the relevant state). (g) The obligations of the Holders to pay the Purchase Price are non-recourse obligations and, except to the extent satisfied by 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. (h) The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates thereof to the Holder of the related Security unless the Company shall have received payment in full for the aggregate Purchase Price for the Common Stock to be purchased thereunder in the manner herein set forth. Section 5.03. Issuance of Shares of Common Stock. Unless a Termination Event or an Early Settlement shall have occurred, subject to Section , on the Purchase Contract Settlement Date upon receipt of the aggregate Purchase Price payable on all Outstanding Securities, the Company shall issue and deposit with the Purchase Contract Agent, for the benefit of the Holders of the Outstanding Securities, one or more certificates representing newly issued shares of Common Stock registered in the name of the Purchase Contract Agent (or its nominee) as custodian for the Holders (such certificates for shares of Common Stock, together with any dividends or distributions for which a record date and payment date for such dividend or distribution has occurred after the Purchase Contract Settlement Date, being hereinafter referred to as the "Purchase Contract Settlement Fund") to which the Holders are entitled hereunder. 38 Subject to the foregoing, upon surrender of a Certificate to the Purchase Contract Agent on or after the Purchase Contract Settlement Date or 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 whole shares of Common Stock which such Holder is entitled to receive pursuant to the provisions of this Article Five (after taking into account all Securities then held by such Holder), together with cash in lieu of fractional shares as provided in Section and any dividends or distributions with respect to such shares constituting part of the 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 Purchase Contract Agent. If any shares of Common Stock issued in respect of a Purchase Contract are to be registered to a Person other than the Person in whose name the Certificate evidencing such Purchase Contract is registered, no such registration shall be made unless the Person requesting such registration has paid any transfer and other taxes required by reason of such registration in a name other than that of the registered Holder of the Certificate evidencing such Purchase Contract or has established to the satisfaction of the Company that such tax either has been paid or is not payable. Section 5.04. Adjustment of Settlement Rate. (a) Adjustments for Dividends, Distributions, Stock Splits, Etc. (1) In case the Company shall pay or make a dividend or other distribution on Common Stock in Common Stock, the Settlement Rate in effect at the opening of business on the day following the date fixed for the determination of shareholders entitled to receive such dividend or other distribution shall be increased by dividing such Settlement Rate by a fraction of which: (i) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination; and (ii) the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (1), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (2) In case the Company shall issue rights, warrants or options to all holders of its Common Stock (not being available on an equivalent basis to Holders of the Securities upon settlement of the Purchase Contracts underlying such Securities) entitling them, for a period expiring within 45 days after the record date for the determination of shareholders entitled to 39 receive such rights, warrants or options, the Settlement Rate in effect at the opening of business on the day following the date fixed for such determination shall be increased by dividing such Settlement Rate by a fraction of which: (i) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such Current Market Price; and (ii) the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (2), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company 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. (3) In case outstanding shares of Common Stock shall be subdivided or split into a greater number of shares of Common Stock, the Settlement Rate in effect at the opening of business on the day following the day upon which such subdivision or split becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Settlement Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision, split or combination becomes effective. (4) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including securities, but excluding any rights, warrants or options referred to in paragraph (2) of this Section 5.04(a), any dividend or distribution paid exclusively in cash and any dividend or distribution referred to in paragraph (1) of this Section 5.04(a)), the Settlement Rate shall be adjusted so that the same shall equal the rate determined by dividing the Settlement Rate in effect immediately prior to the close of business on the date fixed for the determination of shareholders entitled to receive such distribution by a fraction of which: (i) the numerator shall be the Current Market Price per share of Common Stock on the date fixed for such determination less the then fair market value (as reasonably 40 determined by the Board of Directors, whose determination shall be conclusive and the basis for which shall be described in a Board Resolution) of the portion of the assets or evidences of indebtedness so distributed applicable to one share of Common Stock; and (ii) the denominator shall be such Current Market Price per share of Common Stock, such adjustment to become effective immediately prior to the opening of business on the day following the date fixed for the determination of shareholders entitled to receive such distribution. In any case in which this paragraph (4) is applicable, paragraph (2) of this Section 5.04(a) shall not be applicable. In the event that such dividend or distribution is not so paid or made, the Settlement Rate shall again be adjusted to be the Settlement Rate which would then be in effect if such dividend or distribution had not been declared. (5) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding: (i) any quarterly cash dividend on Common Stock to the extent that the aggregate cash dividend per share of Common Stock in any fiscal quarter does not exceed $____ per share (as adjusted from time to time to reflect the subdivisions or combinations of Common Stock, the "Dividend Threshold"), and (ii) any dividend or distribution in connection with the liquidation, dissolution or termination of the Company, whether voluntary or involuntary), then, in such case, the Settlement Rate shall be increased so that the same shall equal the rate determined by dividing the Settlement Rate in effect immediately prior to the close of business on such record date by a fraction of which: (i) the numerator shall be the Current Market Price of Common Stock on the record date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock; and (ii) the denominator shall be the Current Market Price of Common Stock, such increase to be effective immediately prior to the opening of business on the day following the record date; provided, however, that in the event the portion of cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price per share of Common Stock on the record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of a Security shall have the right to receive upon settlement of the Securities the amount of cash such Holder would have received had such Holder settled each Security on the record date. In the event that such dividend or distribution is not so paid or made, the Settlement Rate shall again be adjusted to be the Settlement Rate which would then be in effect if such dividend or distribution had not been declared. If any adjustment is required to be made as 41 set forth in this Section 5.04(a)(5) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the Dividend Threshold. If an adjustment is required to be made as set forth in this Section 5.04(a)(5) above as a result of a distribution that is not a quarterly dividend, such adjustment shall be based upon the full amount of the distribution. (6) In case a tender or exchange offer made by the Company or any subsidiary of the Company for all or any portion of Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to shareholders (based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of Purchased Shares as herein defined) of (I) an aggregate consideration having a fair market value (as reasonably determined by the Board of Directors, whose determination shall be conclusive and the basis for which shall be described in a Board Resolution) that combined together with the aggregate of the cash plus the fair market value (as reasonably determined by the Board of Directors, whose determination shall be conclusive and the basis for which shall be described in a Board Resolution), as of the expiration of such tender or exchange offer, of consideration payable in respect of any other tender or exchange offer, by the Company or any subsidiary of the Company for all or any portion of Common Stock expiring within the 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment pursuant to this paragraph (6) has been made, and (II) the aggregate amount of any distributions to all holders of Common Stock made exclusively in cash within the 12 months preceding the expiration of such tender or exchange offer and in respect of which no adjustment pursuant to paragraph (6) has been made, exceeds 15% of the product of the Current Market Price per share of Common Stock as of the last time (the "Expiration Time") tenders could have been made pursuant to such tender or exchange offer (as it may be amended) times the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the date of the Expiration Time, the Settlement Rate shall be adjusted so that the same shall equal the rate determined by dividing the Settlement Rate immediately prior to the close of business on the date of the Expiration Time by a fraction: (i) the numerator of which shall be equal to (A) the product of (I) the Current Market Price per share of Common Stock on the date of the Expiration Time and (II) the number of shares of Common Stock outstanding (including any tendered shares) on the Expiration Time less (B) the amount of cash plus the fair market value (determined as aforesaid) of the aggregate consideration payable to shareholders based on the transactions described in clauses (I) and (II) above (assuming in the case of clause (I) the acceptance, up to any maximum specified in the terms of the tender or exchange offer, of Purchased Shares); and (ii) the denominator of which shall be equal to the product of (A) the Current Market Price per share of Common Stock as of the Expiration Time and (B) the number of shares of Common Stock outstanding (including any tendered shares) as of the Expiration Time less the number of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred 42 to as the "Purchased Shares"). (7) 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: (i) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of shareholders entitled to receive such distribution" and the "date fixed for such determination" within the meaning of paragraph (4) of this Section); and (ii) a subdivision, split or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision or split becomes effective" or "the day upon which such combination becomes effective", as the case may be, and "the day upon which such subdivision, split or combination becomes effective" within the meaning of paragraph (3) of this Section). (8) The "Current Market Price" per share of Common Stock on any date of determination means the average of the daily Closing Prices for the five consecutive Trading Days selected by the Company commencing not more than 30 Trading Days before, and ending not later than the earlier of 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 on such exchange or in such market without the right to receive such issuance or distribution. (9) All adjustments to the 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 adjustment 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 adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment. If an adjustment is made to the Settlement Rate pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.04(a), an adjustment shall also be made to the Applicable Market Value solely to determine which of clauses (i), (ii) or (iii) of the definition of Settlement Rate in Section 5.01 will apply on the Purchase Contract Settlement Date. Such adjustment shall be made by multiplying the Applicable Market Value by a fraction of which the numerator shall be the Settlement Rate immediately after such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.04(a) and the denominator shall be the Settlement Rate immediately prior to such adjustment; provided, however, that if such adjustment to the Settlement Rate is required to be made pursuant to the occurrence of any of the events contemplated by paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.04(a) during the period taken into consideration for 43 determining the Applicable Market Value, appropriate and customary adjustments shall be made to the Settlement Rate. (10) The Company may, but shall not be required to, make such increases in the Settlement Rate, in addition to those required by this Section, as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes or for any other reason. (b) Adjustment for Consolidation, Merger or Other Reorganization Event. (1) In the event of: (i) any consolidation or merger of the Company with or into another Person (other than a merger or consolidation in which the Company is the continuing corporation and in which the shares of Common Stock outstanding immediately prior to the merger or consolidation are not exchanged for cash, securities or other property of the Company or another corporation); (ii) any sale, transfer, lease or conveyance to another Person of the property of the Company as an entirety or substantially as an entirety; (iii) any statutory share exchange of the Company with another Person (other than in connection with a merger or acquisition); or (iv) any liquidation, dissolution or termination of the Company other than as a result of or after the occurrence of a Termination Event, (any such event, a "Reorganization Event"), the Settlement Rate will be adjusted to provide that each Holder of Securities will receive on the Purchase Contract Settlement Date with respect to each Purchase Contract forming a part thereof, the kind and amount of securities, cash and other property receivable upon such Reorganization Event (without any interest thereon, and without any right to dividends or distribution thereon which have a record date that is prior to the Purchase Contract Settlement Date) by a Holder of the number of shares of Common Stock issuable on account of each Purchase Contract if the Purchase Contract Settlement Date had occurred immediately prior to such Reorganization Event, assuming such Holder of Common Stock is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a "Constituent Person"), or an Affiliate of a Constituent Person to the extent such Reorganization Event provides for different treatment of Common Stock held by Affiliates of the Company and non-affiliates and such Holder failed to exercise his rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such Reorganization Event (provided 44 that if the kind or amount of securities, cash and other property receivable upon such Reorganization Event is not the same for each share of Common Stock held immediately prior to such Reorganization Event by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("Non-electing Share"), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such Reorganization Event by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). In the event of such a Reorganization Event, the Person formed by such consolidation, merger or exchange or the Person which acquires the assets of the Company or, in the event of a liquidation, dissolution or termination of the Company, the Company or a liquidating trust created in connection therewith, shall execute and deliver to the Purchase Contract Agent an agreement supplemental hereto providing that each Holder of an Outstanding Security shall have the rights provided by this Section 5.04(b). Such supplemental agreement shall provide for adjustments which, for events subsequent to the effective date of such supplemental agreement, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section. The above provisions of this Section shall similarly apply to successive Reorganization Events. (2) In the event of a consolidation or merger of the Company with or into another Person, any merger of another Person into the Company (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) in which 30% or more of the total consideration paid to the Company's shareholders consists of cash or cash equivalents, then a Holder of a Security may settle his Purchase Contract for cash as described in Section 5.02(a)(i) or 5.02(d)(i) hereof, as applicable, during the one week period beginning on the twenty-third Trading Day following the closing date of such merger (the "Early Settlement Week"), at the applicable Settlement Rate. For the purposes of this Section, the twenty-third Trading Day after the closing of the merger or consolidation shall be deemed to be the Purchase Contract Settlement Date for the purpose of determining the Applicable Market Value and the deadline for submitting the notice to settle early and the related cash payment shall be 5:00 p.m. (New York City time) of the last Business Day of the Early Settlement Week. Notwithstanding the foregoing, no early settlement will be permitted under this Section 5.04(b)(2) unless, at the time such early settlement is effected, there is an effective Registration Statement with respect to the shares of Common Stock 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 either the Company or the Purchase Contract Agent) under the Securities Act. If such a Registration Statement is so required, the Company covenants and agrees to use its best efforts to (A) have in effect a Registration Statement covering the shares of Common Stock to be delivered in respect of the Purchase Contracts being settled and (B) provide a Prospectus in connection therewith, in each case in a form that the Purchase Contract Agent may use in connection with such early settlement. 45 (c) All calculations and determinations pursuant to this Section 5.04 shall be made by the Company or its agent and the Purchase Contract Agent shall have no responsibility with respect thereto. Section 5.05. Notice of Adjustments and Certain Other Events. (a) Whenever the Settlement Rate is adjusted as herein provided, the Company shall: (i) forthwith compute the adjusted Settlement Rate in accordance with Section 5.04 and prepare and transmit to the Purchase Contract Agent an Officers' Certificate setting forth the Settlement Rate, the method of calculation thereof in reasonable detail, and the facts requiring such adjustment and upon which such adjustment is based; and (ii) within 10 Business Days following the occurrence of an event that requires an adjustment to the Settlement Rate pursuant to Section 5.04 (or if the Company is not aware of such occurrence, as soon as practicable after becoming so aware), provide a written notice to the Holders of the Securities of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Settlement Rate was determined and setting forth the adjusted Settlement Rate. (b) The Purchase Contract Agent shall not at any time be under any duty or responsibility to any Holder of Securities to determine whether any facts exist which may require any adjustment of the Settlement Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. The Purchase Contract Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at the time be issued or delivered with respect to any Purchase Contract; and the Purchase Contract Agent makes no representation with respect thereto. The Purchase Contract Agent shall not be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock pursuant to a Purchase Contract or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Section 5.06. Termination Event; Notice. The Purchase Contracts and all obligations and rights of the Company and the Holders thereunder, including, without limitation, the rights of the Holders to receive and the obligation of the Company to pay any Purchase Contract Payments (including any deferred or accrued and unpaid Purchase 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 Purchase Contract Agent or the Company, if, prior to or on the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon and after the occurrence of a Termination Event, the Securities shall thereafter represent the right to receive the Notes, the Treasury Securities or the 46 appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case may be, forming part of such Securities, 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 Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register. Section 5.07. Intentionally Omitted. Section 5.08. Intentionally Omitted. Section 5.09. No Fractional Shares. No fractional shares or scrip representing fractional shares of Common Stock shall be issued or delivered upon settlement on the Purchase Contract Settlement Date or upon Early Settlement of any Purchase Contracts. If Certificates evidencing more than one Purchase Contract shall be surrendered for settlement at one time by the same Holder, the number of full shares of Common Stock which shall be delivered upon settlement shall be computed on the basis of the aggregate number of Purchase Contracts evidenced by the Certificates so surrendered. Instead of any fractional share of Common Stock which would otherwise be deliverable upon settlement of any Purchase Contracts on the Purchase Contract Settlement Date or upon Early Settlement, the Company, through the Purchase Contract Agent, shall make a cash payment in respect of such fractional interest in an amount equal to the value of such fractional shares times the Applicable Market Value. The Company shall provide the Purchase Contract Agent from time to time with sufficient funds to permit the Purchase Contract Agent to make all cash payments required by this Section 5.09 in a timely manner. Section 5.10. Charges and Taxes. The Company will pay all stock transfer and similar taxes attributable to the initial issuance and delivery of the shares of Common Stock pursuant to the Purchase Contracts; provided, however, 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 Security 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 Securities evidenced thereby, other than in the name of the Purchase Contract Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Certificates unless 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. Section 5.11. Purchase Contract Payments. (a) Subject to Section 5.12, the Company shall pay, on each Payment Date, the 47 Purchase Contract Payments payable in respect of each Purchase Contract to the Person in whose name a Certificate is registered at the close of business on the Record Date next preceding such Payment Date. The Purchase Contract Payments will be payable at the office of the Purchase Contract Agent in New York City maintained for that purpose or, at the option of the Holder, by check mailed to the address of the Person entitled thereto at such Person's address as it appears on the Security Register. If any date on which Purchase Contract Payments are to be made is not a Business Day, then payment of the Purchase 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 any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment will be made on the immediately preceding Business Day. Purchase Contract Payments payable for any period will be computed (i) for any full quarterly period on the basis of a 360-day year of twelve 30-day months and (ii) for any period shorter than a full quarterly period, on the basis of a 30-day month and, for periods of less than a month, on the basis of the actual number of days elapsed per 30-day month. (b) Upon the occurrence of a Termination Event, the Company's obligation to pay future Purchase Contract Payments (including any accrued or deferred Purchase 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 reestablishment of Stock Purchase Units) any other Certificate shall carry the right to accrued or deferred and unpaid Purchase Contract Payments and the right to accrue Purchase Contract Payments, which rights were carried by the Purchase Contracts underlying such other Certificates. (d) Subject to Section 5.04, in the case of any Security with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date that is after any Record Date and prior to or on the next succeeding Payment Date, Purchase Contract Payments otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Early Settlement, and such Purchase Contract Payments shall be paid to the Person in whose name the Certificate evidencing such Security is registered at the close of business on such Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date, Purchase Contract Payments that would otherwise be payable after the Early Settlement Date with respect to such Purchase Contract shall not be payable. Section 5.12. Deferral of Purchase Contract Payments. (a) The Company has the right to defer payment of all or part of the Purchase Contract Payments in respect of each Purchase Contract until no later than the Purchase Contract Settlement Date, but only if the Company shall give the Holders and the Purchase Contract Agent written notice of its election to defer such 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 48 Company is required to give notice of the Record Date or Payment Date with respect to payment of such Purchase Contract Payments to the NYSE or other applicable self-regulatory organization or to Holders of the Securities, but in any event not less than one Business Day prior to such Record Date. If the Company so elects to defer Purchase Contract Payments, the Company shall pay additional Purchase Contract Payments on such deferred installments of Purchase Contract Payments at a rate equal to ___% per annum, compounding quarterly, until such deferred installments are paid in full. Deferred Purchase Contract Payments shall be due on the Payment Date except to the extent that payment is deferred pursuant to this Section. Except as otherwise provided in Section 5.11(d), in the case of any Security with respect to which Early Settlement of the underlying Purchase Contract is effected on an Early Settlement Date, the Holder will have no right to receive any accrued or deferred Purchase Contract Payments. (b) In the event the Company elects to defer the payment of Purchase Contract Payments on the Purchase Contracts until the Purchase Contract Settlement Date, each Holder will receive on the Purchase Contract Settlement Date the aggregate amount of accrued and unpaid Purchase Contract Payments. The Company shall pay such amounts on the Purchase Contract Settlement Date in the manner described in Section 5.02(e). (c) In the event the Company exercises its option to defer the payment of Purchase Contract Payments, then, until all deferred Purchase Contract Payments have been paid, the Company shall not, and shall not permit any of its subsidiaries to (a) make any payment of principal, interest or premium, if any, on or repay, repurchase or redeem any debt securities that rank junior to the Notes in the right of payment issued by the Company or any subsidiary of the Company, or (b) make any guarantee payments with respect to any guarantee by the Company of any securities of any of its subsidiaries if such guarantee ranks junior to the Notes in the right of payment, (c) declare or pay any dividends or distributions on any of the Company's capital stock or (d) redeem, purchase, acquire or make a liquidation payment with respect to, any of the Company's capital stock. Notwithstanding the foregoing, the Company may (1) purchase or acquire its capital stock in connection with the satisfaction by it of its obligations under any employee benefit plans or pursuant to any contract or security outstanding on the first day of any such event requiring it to purchase its capital stock; (2) reclassify its capital stock or exchange or convert one class or series of its capital stock for another class or series of its capital stock; (3) purchase fractional interests in shares of its capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; (4) declare dividends or distributions in its capital stock; and (5) redeem or repurchase any rights pursuant to a rights agreement. ARTICLE 6 Remedies Section 6.01. Unconditional Right of Holders to Receive Purchase Contract Payments and to Purchase Shares of Common Stock. Each Holder of a Security shall have the right, which is absolute and unconditional, (i) subject to the right of the Company to defer such payments in accordance with Section 5.12, to 49 receive each Purchase Contract Payment with respect to the Purchase Contract comprising part of such Security on the respective Payment Date for such Security and (ii) to purchase shares of Common Stock pursuant to such Purchase Contract and, in each such case, to institute suit for the enforcement of any such right to receive Purchase Contract Payments and the right to purchase shares of Common Stock, and such rights shall not be impaired without the consent of such Holder. Section 6.02. Restoration of Rights and Remedies. 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. Section 6.03. Rights and Remedies Cumulative. 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. Section 6.04. Delay or Omission Not Waiver. No delay or omission of any Holder to exercise any right 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 or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by such Holders. Section 6.05. Undertaking for Costs. All parties to this Agreement agree, and each Holder of a Security, by its acceptance of such Security 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 Purchase Contract Agent for any action taken, suffered or omitted by it as 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 Purchase Contract Agent, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% of the Outstanding Securities, or to any suit instituted 50 by any Holder for the enforcement of interest on any Notes or Purchase Contract Payments on or after the respective Payment Date therefor in respect of any Security held by such Holder, or for enforcement of the right to purchase shares of Common Stock under the Purchase Contracts constituting part of any Security held by such Holder. Section 6.06. Waiver of Stay or Extension Laws. 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 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. ARTICLE 7 The Purchase Contract Agent Section 7.01. Certain Duties and Responsibilities. (a) The Purchase Contract Agent: (1) undertakes to perform, with respect to the Securities, such duties and only such duties as are specifically set forth in this Agreement and the Pledge Agreement, and no implied covenants or obligations shall be read into this Agreement or the Pledge Agreement against the Purchase Contract Agent; and (2) in the absence of bad faith or gross negligence on its part, may, with respect to the Securities, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Purchase Contract Agent and conforming to the requirements of this Agreement or the Pledge 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 Purchase Contract Agent, the 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 or the Pledge 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 or the Pledge Agreement shall be construed to relieve the 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: 51 (1) this SubSection shall not be construed to limit the effect of Subsection (a) of this Section; (2) the Purchase Contract Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Purchase Contract Agent was negligent in ascertaining the pertinent facts; (3) no provision of this Agreement or the Pledge Agreement shall require the 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 indemnity satisfactory to the Purchase Contract Agent is not provided to it; and (4) the Purchase Contract Agent shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities. (c) Whether or not therein expressly so provided, every provision of this Agreement and the Pledge Agreement relating to the conduct or affecting the liability of or affording protection to the Purchase Contract Agent shall be subject to the provisions of this Section. (d) The Purchase Contract Agent is authorized to execute and deliver the Pledge Agreement in its capacity as Purchase Contract Agent. Section 7.02. Notice of Default.

A Holder of Treasury Stock Purchase Unit who does not effect, prior to or on 11:00 a.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, an effective Cash Settlement, or who does not effect on or prior to 5:00 p.m. (New York City time) on the seventh Business Day prior to the Purchase Contract Settlement Date an effective Early Settlement, shall pay the Purchase Price for the shares of Common Stock to be issued under the related 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 Purchase Contract or deliver any certificates therefor to the Holder unless it shall have B-6 received payment of the aggregate purchase price for the shares of Common Stock to be purchased thereunder in the manner herein set forth. Each Purchase Contract evidenced hereby and all obligations and rights of the Company and the Holder thereunder shall terminate if a Termination Event shall occur. Upon the occurrence of a Termination Event, the Company shall give written notice to the Purchase Contract Agent and to 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) forming a part of each Treasury Stock Purchase Unit. A Treasury Stock Purchase Unit shall thereafter represent the right to receive the interest in the Treasury Security forming a part of such Treasury Stock Purchase Unit, in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. The Treasury Stock Purchase Units Certificates are issuable only in registered form and only in denominations of a single Treasury Stock Purchase and any integral multiple thereof. The transfer of any Treasury Stock Purchase Certificate will be registered and Treasury Stock Purchase Certificates may be exchanged as provided in the Purchase Contract Agreement. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents permitted by the Purchase Contract Agreement. No service charge shall be required for any such registration of transfer or exchange, but the Company and the Purchase Contract Agent may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. A Holder who elects to substitute Notes, for Treasury Securities, thereby recreating Stock Purchase Units, shall be responsible for any fees or expenses associated therewith. Except as provided in the Purchase Contract Agreement, for so long as the Purchase Contract underlying a Treasury Stock Purchase Unit remains in effect, such Treasury Stock Purchase Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Treasury Stock Purchase Unit in respect of the Treasury Security and the Purchase Contract constituting such Treasury Stock Purchase Unit may be transferred and exchanged only as a Treasury Stock Purchase Unit. A Holder of Treasury Stock Purchase Units may recreate Stock Purchase Units by delivering to the Securities Intermediary Notes with an aggregate principal amount, equal to the aggregate principal amount at maturity of the Pledged Treasury Securities in exchange for the release of such Pledged Treasury Securities in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after such substitution, the Holder's Security shall be referred to as a "STOCK PURCHASE UNIT". Any such creation of Stock Purchase Units may be effected only in multiples of [40] Treasury Stock Purchase Units for [40] Stock Purchase Units. A Holder of Stock Purchase Units may recreate Treasury Stock Purchase Units by delivering to the Securities Intermediary Treasury Securities in an aggregate principal amount equal to the aggregate principal amount at maturity of the Pledged Notes, as the case may be, in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Any such recreation of Treasury Stock Purchase Units may be effected only in multiples of [40] Stock Purchase Units for [40] Treasury Stock Purchase Units. B-7 If a Tax Event Redemption has occurred, a Treasury Stock Purchase Unit Holder may not recreate Stock Purchase Units, and a Stock Purchase Unit Holder may not create a Treasury Stock Purchase Unit. The Company shall pay, on each Payment Date, the Purchase Contract Payments payable in respect of each Purchase Contract to the Person in whose name the Treasury Stock Purchase Units Certificate evidencing such Purchase Contract is registered at the close of business on the Record Date for such Payment Date. Purchase Contract Payments will be payable at the office of the Purchase Contract Agent in New York City or, at the option of the Holder, by check mailed to the address of the Person entitled thereto at such address as it appears on the Security Register. The Company has the right to defer payment of all or part of the Purchase Contract Payments in respect of each Purchase Contract until no later than the Purchase Contract Settlement Date. If the Company so elects to defer Purchase Contract Payments, the Company shall pay additional Purchase Contract Payments on such deferred installments of Purchase Contract Payments at a rate equal to ___% per annum, compounding quarterly, until such deferred installments are paid. In the event that the Company elects to defer the payment of Purchase Contract Payments on the Purchase Contracts until the Purchase Contract Settlement Date), each Holder will receive on the Purchase Contract Settlement Date the aggregate amount of accrued and unpaid Purchase Contract Payments. The Purchase Contracts and all obligations and rights of the Company and the Holders thereunder, including, without limitation, the rights of the Holders to receive and the obligation of the Company to pay any Purchase Contract Payments, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Purchase Contract Agent or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no event later than two Business Days thereafter give written notice to the Purchase Contract Agent, the Collateral Agent and the Holders, at their addresses as they appear in the Security Register. Upon and after the occurrence of a Termination Event, the Collateral Agent shall release the Treasury Securities from the Pledge in accordance with the provisions of the Pledge Agreement. A Treasury Stock Purchase Unit shall thereafter represent the right to receive the interest in the Treasury Security forming a part of such Treasury Stock Purchase Unit, in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Upon registration of transfer of this Treasury Stock Purchase Certificate, the transferee shall be bound (without the necessity of any other action on the part of such transferee, except as may be required by the Purchase Contract Agent pursuant to the Purchase Contract Agreement), under the terms of the Purchase Contract Agreement and the Purchase Contracts evidenced hereby and the transferor shall be released from the obligations under the Purchase Contracts evidenced by this Treasury Stock Purchase Units 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. B-8 The Holder of this Treasury Stock Purchase Units Certificate, by its acceptance hereof, authorizes the Purchase Contract Agent to enter into and perform the related Purchase Contracts forming part of the Treasury Stock Purchase Units evidenced hereby on its behalf as its attorney-in-fact, expressly withholds any consent to the assumption (i.e., affirmance) of the Purchase Contracts by the Company or its trustee in the event that the Company becomes the subject of a case under the Bankruptcy Code, agrees to be bound by the terms and provisions thereof, covenants and agrees to perform its obligations under such Purchase Contracts, consents to the provisions of the Purchase Contract Agreement, authorizes the Purchase Contract Agent to enter into and perform the Purchase Contract Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and consents to the Pledge of the Treasury Securities underlying this Treasury Stock Purchase Units Certificate pursuant to the Pledge Agreement.

Subject to certain exceptions, the provisions of the Purchase Contract Agreement may be amended with the consent of the Holders of a majority of the Purchase Contracts. The Purchase Contracts shall for all purposes be governed by, and construed in accordance with, the laws of the State of New York, without regard to conflicts of laws principles thereof.
