SECTION 1.03. FORM OF DOCUMENTS DELIVERED TO PURCHASE CONTRACT AGENT. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

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 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 Units shall be proved by the Security Register. (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Unit shall bind every future Holder of the same Unit and the Holder of 14 every Certificate evidencing such Unit 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 Units entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Agreement to be given, made or taken by Holders of Units. If any record date is set pursuant to this paragraph, the Holders of the Outstanding Corporate Units and the Outstanding Treasury Units, as the case may be, on such record date, and no other Holders, shall be entitled to take the relevant action with respect to the Corporate Units or the Treasury Units, as the case may be, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken prior to or on the applicable Expiration Date by Holders of the requisite number of Outstanding Units on such record date. Nothing 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 of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite number of Outstanding Units on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Purchase Contract Agent in writing and to each Holder of Units in the manner set forth in Section 1.06. With respect to any record date set pursuant to this Section 1.04(e), the Company may designate any date as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Purchase Contract Agent in writing, and to each Holder of Units 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. SECTION 1.05. NOTICES. Any notice, consent, waiver, communication or Act of Holders 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: (a) the Purchase Contract Agent by any Holder or by the Company shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, to the 15 Agent at 25 Park Place, 24th Floor, Atlanta, Georgia 30303, Telecopy: (404) 588-7335, Attention: Corporate Trust Department, or at any other address previously furnished in writing by the Agent to the Holders and the Company; (b) the Company by the Purchase Contract Agent or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, to the Company at ONEOK, Inc., 100 West Fifth Street, Tulsa, Oklahoma 74103, Telecopy: (918) 588-7971, Attention: Chief Financial Officer, or at any other address previously furnished in writing to the Agent by the Company, with a copy to Gable & Gotwals, 1100 ONEOK Plaza, 100 West Fifth Street, Tulsa, Oklahoma 74103, Attention: John Barker; (c) the Collateral Agent by the Purchase Contract Agent, the Company or any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Collateral Agent at ________________________________________, Telecopy: ______________, Attention: _____________________, or at any other address previously furnished in writing by the Collateral Agent to the Agent, the Company and the Holders; or (d) the Indenture Trustee by the Company shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and personally delivered or mailed, first-class postage prepaid, addressed to the Indenture Trustee at SunTrust Bank, 25 Park Place, 24th Floor, Atlanta, Georgia 30303, Telecopy: (404) 588-7335, Attention: Corporate Trust Department, or at any other address previously furnished in writing by the Indenture Trustee to the Company.

NOTICE TO HOLDERS; WAIVER.

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 16 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.

In any case where any Payment Date shall not be a Business Day (notwithstanding any other provision of this Agreement or the Units), Contract Adjustment Payments or other distributions shall not be paid on such date, but Contract Adjustment 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. In any case where the Purchase Contract Settlement Date or any Early Settlement Date or Cash Merger Early Settlement Date shall not be a Business Day (notwithstanding any other provision of this Agreement or the Units), Purchase Contracts shall not be performed and Early Settlement and Cash Merger Early Settlement shall not be effected on such date, but Purchase Contracts shall be performed or Early Settlement or Cash Merger Early Settlement shall be effected, as applicable, 17 on the next succeeding Business Day with the same force and effect as if made on such Purchase Contract Settlement Date, Early Settlement Date or Cash Merger Early Settlement Date, as applicable.

Any such appointment shall not relieve the Company in any way from its obligations hereunder. SECTION 1.16. NO WAIVER. No failure on the part of the Company, the Purchase Contract Agent, the Collateral Agent, the Securities Intermediary or any of their respective agents to exercise, and no course of dealing with respect to, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Company, the Collateral Agent, the Securities Intermediary or any of their respective agents of any right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law. ARTICLE II CERTIFICATE FORMS SECTION 2.01. FORMS OF CERTIFICATES GENERALLY.

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 officer of the Purchase Contract Agent, as such Holder's attorney-in-fact. Such signature by an authorized officer of the Purchase Contract Agent shall be conclusive evidence that the Holder of such Certificate has entered into the Purchase Contracts evidenced by such Certificate.

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 3.04, 3.06 and 8.05 not involving any transfer.

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 23 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, without limitation, making Contract Adjustment Payments, if any, and receiving approvals, votes or consents hereunder) as the Holder of the Units and the sole holder of the Global Certificates and shall have no obligation to the Beneficial Owners; (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. The Depositary will make book entry transfers among Depositary Participants and receive and transmit payments of Contract Adjustment Payments to such Depositary Payments. Transfers of securities evidenced by Global Certificates shall be made through the facilities of the Depositary, and any cancellation of, or increase or decrease in the number of, such securities (including the creation of Treasury Units and the recreation of Corporate Units pursuant to Sections 3.13 and 3.14 respectively) shall be accomplished by making appropriate annotations on the Schedule of Increases and Decreases for such Global Certificate.

Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company's agent shall give such notices and communications to the Holders and, with respect to any Units 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 Units, the Company may, in its sole discretion, appoint a successor Depositary with respect to the Units.

If: (i) the Depositary notifies the Company that it is unwilling or unable to continue its services as securities depositary with respect to the Units and no successor Depositary has been appointed pursuant to Section 3.08 within 90 days after such notice; or 24 (ii) the Depositary ceases to be a "clearing agency" registered under Section 17A of the Exchange Act when the Depositary is required to be so registered to act as the Depositary and so notifies the Company, and no successor Depositary has been appointed pursuant to Section 3.08 within 90 days after such notice; or (iii) the Company determines in its discretion that the Global Certificates shall be exchangeable for definitive Certificates, then (x) definitive Certificates shall be prepared by the Company with respect to such Units and delivered to the Purchase Contract Agent and (y) upon surrender of the Global Certificates representing the Units by the Depositary, accompanied by registration instructions, the Company shall cause definitive Certificates to be delivered to Beneficial Owners in accordance with the instructions of the Depositary. The Company and the Purchase Contract Agent shall not be liable for any delay in delivery of such instructions and may conclusively rely on and shall be authorized and protected in relying on, such instructions. Each definitive Certificate so delivered shall evidence Units 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 at the cost of the Holder, evidencing the same number of Corporate Units or Treasury Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding. If there shall be delivered to the Company and the Purchase Contract Agent (i) evidence to their satisfaction of the destruction, loss or theft of any Certificate, and (ii) such security or indemnity as may be required by them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Purchase Contract Agent that such Certificate has been acquired by a bona fide purchaser, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Certificate, a new Certificate, evidencing the same number of Corporate Units or Treasury Units, as the case may be, and bearing a Certificate number not contemporaneously outstanding. Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to authenticate, execute on behalf of the Holder, and deliver to the Holder, a Certificate on or after the Business Day immediately preceding the earliest of any Early Settlement Date with respect to such lost or mutilated Certificate, any Cash Merger Early Settlement Date with respect to such lost or mutilated Certificate, the 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: 25 (i) if the Purchase Contract Settlement Date or Early Settlement Date or Cash Merger Early Settlement Date with respect to such lost, stolen, destroyed or mutilated Certificate has occurred, deliver the shares of Common Stock issuable in respect of the Purchase Contracts forming a part of the Units evidenced by such Certificate; or (ii) if a Cash Settlement with respect to such lost or mutilated Certificate or if a Termination Event shall have occurred prior to the Purchase Contract Settlement Date, transfer the Senior Notes, the Treasury Securities or the appropriate Applicable Ownership Interest (as specified in clause (i) of the definition of such term) in 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 V 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 fees and expenses (including, without limitation, the fees and expenses of the Purchase Contract Agent) connected therewith. Every new Certificate issued pursuant to this Section in lieu of any destroyed, lost or stolen Certificate shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Units evidenced thereby, whether or not the destroyed, lost or stolen Certificate (and the Units evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits and be subject to all the obligations of this Agreement equally and proportionately with any and all other Certificates delivered hereunder. The provisions of this Section are exclusive and shall preclude, to the extent lawful, all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Certificates. SECTION 3.11. PERSONS DEEMED OWNERS. Prior to due presentment of a Certificate for registration of transfer, the Company and the Purchase Contract Agent, and any agent of the Company or the Purchase Contract Agent, may treat the Person in whose name such Certificate is registered as the owner of the Units evidenced thereby for purposes of (subject to any applicable record date) any payment or distribution on the Senior Notes or on the Applicable Ownership Interests (as specified in clause (ii) of the definition of such term) in the Treasury Portfolio (if any), as applicable, payment of Contract Adjustment Payments and performance of the Purchase Contracts and for all other purposes whatsoever in connection with such Units, whether or not such payment, distribution, or performance shall be overdue and notwithstanding any notice to the contrary, and neither the Company nor the Purchase Contract Agent, nor any agent of the Company or the Purchase Contract Agent, shall be affected by notice to the contrary. Notwithstanding the foregoing, with respect to any Global Certificate, nothing contained herein shall prevent the Company, the Purchase Contract Agent or any agent of the Company or the Purchase Contract Agent, from giving effect to any written certification, proxy or other 26 authorization furnished by the Depositary (or its nominee), as a Holder, with respect to such Global Certificate, or impair, as between such Depositary and the related Beneficial Owner, the operation of customary practices governing the exercise of rights of the Depositary (or its nominee) as Holder of such Global Certificate. None of the Company, the Purchase Contract Agent or any agent of the Company or the Purchase Contract Agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Certificate or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. SECTION 3.12. CANCELLATION. All Certificates surrendered for delivery of shares of Common Stock on or after the Purchase Contract Settlement Date or upon the transfer of Senior Notes, or for delivery of the appropriate Applicable Ownership Interest in the Treasury Portfolio or Treasury Securities, as the case may be, after the occurrence of a Termination Event or pursuant to a Cash Settlement, an Early Settlement or a Cash Merger Early Settlement, or upon the registration of transfer or exchange of a Unit, or a Collateral Substitution or the recreation of Corporate Units shall, if surrendered to any Person other than the Purchase Contract Agent, be delivered to the Purchase Contract Agent along with appropriate written instructions regarding the cancellation thereof and, if not already cancelled, shall be promptly cancelled by it. The Company may at any time deliver to the 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 an 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 with appropriate written instructions regarding the cancellation thereof. SECTION 3.13. CREATION OF TREASURY UNITS BY SUBSTITUTION OF TREASURY SECURITIES. Unless the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, and subject to the conditions set forth in this Agreement, a Holder may, at any time from and after the date of this Agreement and prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, effect a Collateral Substitution and separate the Senior Notes from the related Purchase Contracts in respect of such Holder's Corporate Units by substituting for such Senior Notes, Treasury Securities in an aggregate principal amount at maturity equal to the aggregate principal amount of such Senior Notes; provided that Holders may make Collateral Substitutions only in integral multiples of __ Corporate Units. 27 To effect such substitution, the Holder must: (1) deposit with the Securities Intermediary Treasury Securities having an aggregate principal amount at maturity equal to the aggregate principal amount of the Senior Notes comprising part of such Corporate Units; and (2) transfer the related Corporate 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 deposited 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 Senior Notes underlying such Corporate Units, whereupon the Purchase Contract Agent shall promptly give such 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 Senior Notes from the Pledge, free and clear of the Company's security interest therein, and the transfer of such Senior Notes to the Purchase Contract Agent on behalf of the Holder. Upon receipt of such Senior Notes, the Purchase Contract Agent shall promptly: (ii) cancel the related Corporate Units; (iii) transfer the Senior Notes to the Holder (such Senior Notes shall be tradeable as a separate security, independent of the resulting Treasury Units); and (iv) authenticate, execute on behalf of such Holder and deliver Treasury Units in book-entry form or, if applicable, in the form of a Treasury 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 Corporate Units. Holders who elect to separate the Senior Notes from the related Purchase Contracts and to substitute Treasury Securities for such Senior Notes shall be responsible for any fees or expenses (including, without limitation, fees and expenses payable to the Collateral Agent for its services as Collateral Agent) in respect of the substitution, and neither the Company nor the Purchase Contract Agent shall be responsible for any such fees or expenses. If the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units and subject to the conditions set forth in this Agreement, a Holder may, at any time on or prior to the second Business Day immediately preceding the Purchase Contract Settlement Date, substitute Treasury Securities for the Applicable Ownership Interests in the Treasury Portfolio included in such Corporate Units, but only in integral multiples of ______ Corporate Units. In such an event, the Holder shall transfer Treasury Securities having an aggregate principal amount at maturity equal to the aggregate Stated Amount of the Purchase Contracts underlying such Corporate Units to the Collateral Agent, and the Purchase Contract Agent shall instruct the Collateral Agent to release the Pledge of and transfer to the Holder the appropriate Applicable Ownership Interests in the Treasury Portfolio in the manner set forth above. 28 In the event a Holder making a Collateral Substitution pursuant to this Section 3.13 fails to effect a book-entry transfer of the Corporate Units or fails to deliver Corporate Units Certificates to the Purchase Contract Agent after depositing Treasury Securities with the Securities Intermediary, any distributions on the Senior Notes or Applicable Ownership Interest in the Treasury Portfolio constituting a part of such Corporate Units shall be held in the name of the Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until such Corporate Units are so transferred or the Corporate 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 Corporate Units Certificate has been destroyed, lost or stolen, together with any indemnity that may be required by the Purchase Contract Agent and the Company. Except as described in Section 5.02 or in this Section 3.13 or in connection with a Cash Settlement, an Early Settlement, a Cash Merger Early Settlement or a Termination Event, for so long as the Purchase Contract underlying a Corporate Unit remains in effect, such Corporate Unit shall not be separable into its constituent parts, and the rights and obligations of the Holder in respect of the Senior Notes or Applicable Ownership Interests in the Treasury Portfolio, as the case may be, and the Purchase Contract comprising such Corporate Units may be acquired, and may be transferred and exchanged, only as a Corporate Unit. SECTION 3.14. RECREATION OF CORPORATE UNITS. Unless the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, and subject to the conditions set forth in this Agreement, a Holder of Treasury Units may recreate Corporate Units at any time on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date; provided that Holders of Treasury Units may only recreate Corporate Units in integral multiples of __ Treasury Units. To recreate Corporate Units, the Holder must: (1) transfer to the Securities Intermediary Senior Notes having an aggregate principal amount equal to the aggregate principal amount at stated maturity of the Treasury Securities comprising part of the Treasury Units; and (2) transfer the related Treasury 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 Senior Notes to the Securities Intermediary and (ii) requesting that the Purchase Contract Agent instruct the Collateral Agent to release the Treasury Securities underlying such Treasury 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 Senior Notes 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 thereof to the Purchase Contract Agent on 29 behalf of the Holder. Upon receipt of such Treasury Securities, the Purchase Contract Agent shall promptly: (ii) cancel the related Treasury Units; (iii) transfer the Treasury Securities to the Holder; and (iv) authenticate, execute on behalf of such Holder and deliver Corporate Units in book-entry form or, if applicable, in the form of a Corporate 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 Units. Holders who elect to recreate Corporate Units shall be responsible for any fees or expenses (including, without limitation, fees and expenses payable to the Collateral Agent for its services as Collateral Agent) in respect of the recreation, and neither the Company nor the Purchase Contract Agent shall be responsible for any such fees or expenses. If the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, a Holder of Treasury Units may at any time on or prior to the second Business Day immediately preceding the Purchase Contract Settlement Date substitute the Applicable Ownership Interests in the Treasury Portfolio in an amount such that the aggregate principal amount at maturity of the portion of such Applicable Ownership Interest specified in clause (i) of the definition of such term is equal to the aggregate Stated Amount of the Purchase Contract underlying such Treasury Units, for Treasury Securities, but only in multiples of ______ Treasury Units. In such an event, the Holder shall transfer the appropriate Applicable Ownership Interests in the Treasury Portfolio to the Collateral Agent, and the Purchase Contract Agent shall instruct the Collateral Agent to release the Pledge of and transfer to the Holder Treasury Securities in the manner set forth above. Except as provided in Section 5.02 or in this Section 3.14 or in connection with a Cash Settlement, an Early Settlement, a Cash Merger Early Settlement or a Termination Event, for so long as the Purchase Contract underlying a Treasury Unit remains in effect, such Treasury Unit shall not be separable into its constituent parts and the rights and obligations of the Holder of such Treasury Unit in respect of the __/____ of a Treasury Security and the Purchase Contract comprising such Treasury Unit may be acquired, and may be transferred and exchanged, only as a Treasury Unit. SECTION 3.15. TRANSFER OF COLLATERAL UPON OCCURRENCE OF TERMINATION EVENT. Upon the occurrence of a Termination Event and the transfer to the Purchase Contract Agent of the Senior Notes, the appropriate Applicable Ownership Interests in the Treasury Portfolio or the Treasury Securities, as the case may be, underlying the Corporate Units and the Treasury 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 Senior Notes, the appropriate Applicable Ownership Interests in 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. 30 Upon book-entry transfer of the Corporate Units or the Treasury Units or delivery of a Corporate Units Certificate or Treasury Units Certificate to the Purchase Contract Agent with such transfer instructions, the Purchase Contract Agent shall transfer the Senior Notes, the appropriate Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, underlying such Corporate Units or Treasury Units, as the case may be, to such Holder by book-entry transfer, or other appropriate procedures, in accordance with such instructions. In the event a Holder of Corporate Units or Treasury Units fails to effect such transfer or delivery, the Senior Notes, the appropriate Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, underlying such Corporate Units or Treasury 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 Corporate Units or Treasury Units or surrender of the Corporate Units Certificate or Treasury Units Certificate or the receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such Corporate Units Certificate or Treasury 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 (ii) the expiration of the time period specified in the abandoned property laws of the relevant State in which the Purchase Contract Agent holds such property. SECTION 3.16. NO CONSENT TO ASSUMPTION. Each Holder of a Unit, by acceptance thereof, shall be deemed expressly to have withheld any consent to the assumption under Section 365 of the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its trustee in bankruptcy, receiver, liquidator or a person or entity performing similar functions, its trustee in the event that the Company becomes a debtor under the Bankruptcy Code or subject to other similar state or federal law providing for reorganization or liquidation. ARTICLE IV THE SENIOR NOTES AND APPLICABLE OWNERSHIP INTERESTS IN THE TREASURY PORTFOLIO SECTION 4.01. INTEREST PAYMENTS; RIGHTS TO INTEREST PAYMENTS PRESERVED. Any payment of interest on any Senior Note or on the appropriate Applicable Ownership Interests (as specified in clause (ii) of the definition of such term) in 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 Corporate Units Certificate (or one or more Predecessor Corporate Units Certificates) of which such Senior Note or the appropriate 31 Applicable Ownership Interests in the Treasury Portfolio, as the case may be, forms a part is registered at the close of business on the Record Date for such Payment Date. Each Corporate Units Certificate evidencing Senior Notes or the appropriate Applicable Ownership Interests in the Treasury Portfolio delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of any other Corporate Units Certificate shall carry the right to accrued and unpaid interest or distributions, and to accrue future interest or distributions, which were carried by the Senior Notes or the appropriate Applicable Ownership Interests in the Treasury Portfolio underlying such other Corporate Units Certificate. In the case of any Corporate Unit with respect to which (A) Cash Settlement of the underlying Purchase Contract is properly effected pursuant to Section 5.02(b) or Section 5.02(e) hereof, (B) Early Settlement of the underlying Purchase Contract is properly effected pursuant to Section 5.07 hereof, (C) Cash Merger Early Settlement of the underlying Purchase Contract is properly effected pursuant to Section 5.04(b)(ii) hereof, (D) a Collateral Substitution is properly effected pursuant to Section 3.13, or (E) a Successful Initial Remarketing occurs with respect to the Senior Note that is part of such Corporate Unit, in each case on a date that is after any Record Date and on or prior to the next succeeding Payment Date, interest on the Senior Notes or distributions with respect to the appropriate Applicable Ownership Interests in the Treasury Portfolio, as the case may be, underlying such Corporate Unit otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Cash Settlement, Early Settlement, Cash Merger Early Settlement, Collateral Substitution or Initial Remarketing, and such payment or distributions shall, subject to receipt thereof by the Purchase Contract Agent, be payable to the Person in whose name the Corporate Units Certificate (or one or more Predecessor Corporate Units Certificates) was registered at the close of business on the Record Date. Except as otherwise expressly provided in the immediately preceding paragraph, in the case of any Corporate Units with respect to which Cash Settlement, Early Settlement or Cash Merger Early Settlement of the underlying Purchase Contract is properly effected, or with respect to which a Collateral Substitution has been effected, payment of interest on the related Senior Notes or distributions with respect to the appropriate Applicable Ownership Interests in the Treasury Portfolio, as the case may be, that would otherwise be payable or made after the Purchase Contract Settlement Date, Early Settlement Date, Cash Merger Early Settlement Date or the date of the Collateral Substitution, as the case may be, shall not be payable hereunder to the Holder of such Corporate Units; provided, however, that to the extent that such Holder continues to hold Separate Senior Notes or Applicable Ownership Interest in the Treasury Portfolio that formerly comprised a part of such Holder's Corporate Units, such Holder shall be entitled to receive the payment of interest on such Separate Senior Notes or distributions on the Applicable Ownership Interests in the Treasury Portfolio. SECTION 4.02. NOTICE AND VOTING. Under and subject to 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 Senior Notes, but only to the extent instructed in writing by the Holders as described below.

Upon the written request of the Holders of Corporate 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 Senior 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 Corporate Unit, the Purchase Contract Agent shall abstain from voting the Senior Notes underlying such Corporate Unit. The Company hereby agrees, if applicable, to solicit Holders of Corporate Units to timely instruct the Purchase Contract Agent in order to enable the Purchase Contract Agent to vote such Senior Notes. The Holders of Corporate Units and Treasury Units shall have no voting or other rights in respect of Common Stock. SECTION 4.03. SPECIAL EVENT REDEMPTION. (a) If the Company elects to redeem the Senior Notes on any Payment Date following the occurrence of a Special Event as permitted by the Indenture, it shall notify the Collateral Agent in writing that a Special Event has occurred and that it intends to redeem the Senior Notes on the Special Event Redemption Date. On the Special Event Redemption Date, the Collateral Agent shall surrender the Pledged Senior Notes to the Indenture Trustee against delivery of an amount equal to the aggregate Redemption Price for such Pledged Senior Notes.

The Company may cause to be made in any Corporate 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 Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio for Senior Notes as Collateral. (c) The Holders of Separate Senior Notes shall directly receive the Redemption Price for the Separate Senior Notes. ARTICLE V THE PURCHASE CONTRACTS SECTION 5.01. PURCHASE OF SHARES OF COMMON STOCK.

If the Remarketing Agent is able to remarket the Pledged Senior Notes and Separate Senior Notes at a price equal to or greater than ______% of the Treasury Portfolio Purchase Price plus the Separate Senior Notes Purchase Price (a "Successful Initial Remarketing"), the Collateral Agent shall, in accordance with the Pledge Agreement, cause the Securities Intermediary to transfer the Pledged Senior Notes upon confirmation of deposit by the Remarketing Agent of the proceeds of such Successful Remarketing in the Collateral Account, and the portion of the proceeds from such Successful Initial Remarketing equal to the Treasury Portfolio Purchase Price will be applied to purchase the Treasury Portfolio. The Remarketing Agent may deduct as a remarketing fee (the "Remarketing Fee") an amount equal to ___ basis points (____%) of the sum of the Treasury Portfolio Purchase Price plus the Separate Senior Notes Purchase Price. With respect to Pledged Senior Notes, any proceeds of the Initial Remarketing in excess of the sum of the Treasury Portfolio Purchase Price plus the Remarketing Fee with respect to such Pledged Senior Notes will be remitted to the Purchase Contract Agent for payment to the Holders of the related Corporate Units. The Treasury Portfolio will be substituted for the Pledged Senior Notes and the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio will be pledged to the Collateral Agent to secure the obligation of the Holders of Corporate Units to pay the Purchase Price for the Common Stock under the related Purchase Contracts on the Purchase Contract Settlement Date. With respect to Separate Senior Notes upon a Successful Initial Remarketing, any proceeds of the Initial Remarketing in excess of the Remarketing Fee attributable to the Separate Senior Notes will be remitted to the Custodial Agent for payment to the holders of Separate Senior Notes. None of the Company, the Purchase Contract Agent, or any Holders of Corporate Units or holders of Separate Senior Notes whose Senior Notes or Separate Senior Notes are so remarketed will otherwise be responsible for the payment of any Remarketing Fee in connection therewith. Following the occurrence of a Successful Initial Remarketing, the Holders of Corporate Units and the Collateral Agent shall have such security interests, rights and obligations with respect to the Applicable Ownership Interests (as specified in clause (i) of the definition of such 37 term) in the Treasury Portfolio as the Holder of Corporate Units and the Collateral Agent had in respect of the Senior Notes, subject to the Pledge thereof as provided in the Pledge Agreement, and any reference herein or in the Certificates to the Senior Notes shall be deemed to be a reference to such Applicable Ownership Interests in the Treasury Portfolio and any reference herein or in the Certificates to interest on the Senior Notes shall be deemed to be a reference to corresponding distributions on such Applicable Ownership Interests in the Treasury Portfolio. The Company may cause to be made in any Corporate 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 such Applicable Ownership Interests in the Treasury Portfolio for Senior Notes. If, in spite of using its reasonable efforts, the Remarketing Agent cannot remarket the Pledged Senior Notes and the Separate Senior Notes (if any) in the Initial Remarketing (other than to the Company) at a price not less than ______% of the sum of the Treasury Portfolio Purchase Price plus the Separate Senior Notes Purchase Price or a condition precedent set forth in the Remarketing Agreement is not fulfilled, the Initial Remarketing will be deemed to have failed (a "Failed Initial Remarketing"). Promptly following a Failed Initial Remarketing, the Remarketing Agent shall return the Pledged Senior Notes and the Separate Senior Notes (if any) subject to such Remarketing to the Collateral Agent or to the Custodial Agent, as the case may be. (ii) Prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the applicable Remarketing Date, but no earlier than the Payment Date immediately preceding such date, Holders of Separate Senior Notes may elect to have their Separate Senior Notes remarketed under the Remarketing Agreement by delivering their Separate Senior Notes, along with a notice of such election, substantially in the form of Exhibit F to the Pledge Agreement, to the Custodial Agent. After such time, such election shall become an irrevocable election to have such Separate Senior Notes remarketed in such Remarketing. The Custodial Agent shall hold Separate Senior Notes in an account separate from the Collateral Account in which the Pledged Senior Notes (as defined in the Pledge Agreement) shall be held. Holders of Separate Senior Notes electing to have their Separate Senior Notes remarketed will also have the right to withdraw that election by written notice to the Custodial Agent, substantially in the form of Exhibit G to the Pledge Agreement, on or prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the applicable Remarketing Date, upon which notice the Custodial Agent shall return such Separate Senior Notes to such Holder. Promptly after 11:00 a.m. on the Business Day immediately preceding the applicable Remarketing Date, the Custodial Agent shall notify the Remarketing Agent of the aggregate principal amount of the Separate Senior Notes to be remarketed and will deliver to the Remarketing Agent for Remarketing all such Separate Senior Notes delivered to the Custodial Agent pursuant to Section 4.07 of the Pledge Agreement and not validly withdrawn prior to such date. (iii) Not later than seven calendar days nor more than 15 calendar days prior to the applicable Remarketing Date, the Company shall request the Depositary or its nominee to notify the Beneficial Owners or Depositary Participants holding Units of the procedures to be followed in such Remarketing. 38 (iv) The Company agrees to use its best efforts to ensure that, if required by applicable law, a registration statement with regard to the full amount of the Senior Notes to be remarketed in the Initial Remarketing or the Final Remarketing, as the case may be, shall be effective with the Securities and Exchange Commission in a form that will enable the Remarketing Agent to rely on it in connection with such Remarketing. (v) The Company shall cause a notice of a Failed Remarketing to be published (with a copy of such notice to be provided to the Purchase Contract Agent) on the Business Day immediately following the applicable Remarketing 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. ----------------------- (b) (i) Unless a Special Event Redemption, an Early Settlement or a Cash Merger Early Settlement has occurred prior to the Final Remarketing Date, if no Successful Remarketing has occurred prior to the Final Remarketing Date, each Holder shall have the right to satisfy such Holder's obligations under the Purchase Contract on the Purchase Contract Settlement Date in cash by notifying the Purchase Contract Agent by use of a notice in substantially the form of Exhibit E hereto of its intention to pay in cash ("Cash Settlement") prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date. Promptly following 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, the Purchase Contract Agent shall notify the Collateral Agent and the Indenture Trustee of the receipt of such notices from Holders intending to make a Cash Settlement. (ii) A Holder of a Corporate Unit who has so notified the Purchase Contract Agent of its intention to effect a Cash Settlement shall pay the Purchase Price to the Collateral Agent for deposit in the Collateral Account prior to 5:00 p.m. (New York City time) on the fourth 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 pursuant to written instructions received from the Company 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 Corporate Unit does not notify the Purchase Contract Agent of its intention to make a Cash Settlement in accordance with Section 5.02(b)(ii) above, or does notify the Purchase Contract Agent in accordance with Section 5.02(b)(i) above but fails to make such payment as required by Section 5.02(b)(ii) above, such Holder shall be deemed to have consented to the disposition of the Pledged Senior Notes pursuant to the Final Remarketing as described in paragraph Section 5.02(c) below. 39 (iv) Promptly after 5:00 p.m. (New York City time) on the fourth Business Day preceding the Purchase Contract Settlement Date, the Collateral Agent, based on cash payments received by the Collateral Agent pursuant to Section 5.02(b)(ii) hereof, shall promptly notify the Purchase Contract Agent and the Indenture Trustee of the aggregate principal amount of Senior Notes to be tendered for purchase in the Remarketing in a notice pursuant to the terms of the Pledge Agreement. (c) (i) Unless a Special Event Redemption, an Early Settlement or a Cash Merger Early Settlement has occurred prior to the Final Remarketing Date, if a Failed Initial Remarketing has occurred, the Senior Notes of such Holders of Corporate Units who have not notified the Purchase Contract Agent of their intention to effect a Cash Settlement as provided in Section 5.02(b)(i) above, or who have so notified the Purchase Contract Agent in accordance with Section 5.02(b)(i) above but have failed to make such payment as required by Section 5.02(b)(ii) above, and the Separate Senior Notes of any holder who has elected for its Separate Senior Notes to be remarketed pursuant to Section 5.02(a)(ii) will be remarketed by the Remarketing Agent (the "Final Remarketing") on the third Business Day immediately preceding the Purchase Contract Settlement Date (the "Final Remarketing Date"). In order to facilitate the Final Remarketing, the Purchase Contract Agent, based on the notices specified in Section 5.02(b)(iv), and the Collateral Agent, based on the notices specified in Section 5.02(a)(ii), shall notify the Remarketing Agent, by 11:00 a.m. (New York City time) on the Business Day immediately preceding the Final Remarketing Date, of the aggregate principal amount of Pledged Senior Notes or aggregate principal amount of Separate Senior Notes that are to be remarketed pursuant to Section 5.02(a)(ii), as the case may be, to be remarketed. Concurrently, the Custodial Agent will present for remarketing the Separate Senior Notes to the Remarketing Agent. (ii) Upon receipt of such notice from the Purchase Contract Agent and the Collateral Agent and the Separate Senior Notes (if any) from the Custodial Agent, as set forth in clause (i) above, the Remarketing Agent shall, on the Final Remarketing Date, use its reasonable efforts to remarket (based on the Reset Rate) such Pledged Senior Notes and the Separate Senior Notes on such date at a price equal to approximately ______% of the aggregate principal amount of such Senior Notes and Separate Senior Notes being remarketed, as provided in the Remarketing Agreement. If the Remarketing Agent is able to remarket the Senior Notes and Separate Senior Notes at a price equal to or greater than _______% of the aggregate principal amount of the Senior Notes and Separate Senior Notes (if any) (a "Successful Final Remarketing"), the Collateral Agent shall, in accordance with the Pledge Agreement, cause the Securities Intermediary to transfer the Pledged Senior Notes upon confirmation of deposit by the Remarketing Agent of the proceeds of such Successful Remarketing in the Collateral Account. The Remarketing Agent may deduct as the remarketing fee (the "Final Remarketing Fee") an amount equal to ______ basis points (______%) of the aggregate principal amount of the remarketed Pledged Senior Notes and Separate Senior Notes (if any). The proceeds from the Remarketing remitted to the Collateral Agent shall be invested by the Collateral Agent in Permitted Investments, in accordance with the Pledge Agreement, and then applied to satisfy in full the obligations of such Holders of Corporate Units to pay the Purchase Price for the shares of Common Stock under the related Purchase Contracts on the Purchase Contract Settlement Date. Any proceeds in excess of those required to pay 40 the Purchase Price and the Final Remarketing Fee will be remitted to the Purchase Contract Agent for payment to the Holders of the related Corporate Units. With respect to Separate Senior Notes upon a Successful Final Remarketing any proceeds of the Final Remarketing in excess of the Final Remarketing Fee attributable to the Separate Senior Notes will be remitted to the Custodial Agent for payment to the holders of Separate Senior Notes. (iii) If, in spite of using its reasonable efforts, the Remarketing Agent cannot remarket the Pledged Senior Notes and Separate Senior Notes (if any) at a price not less than _____% of the aggregate principal amount of the Pledged Senior Notes and Separate Senior Notes to be remarketed in the Final Remarketing (other than to the Company) or a condition precedent set forth in the Remarketing Agreement is not fulfilled, the remarketing will be deemed to have failed (a "Failed Final Remarketing"). Following a Failed Final Remarketing, as of the Purchase Contract Settlement Date, each Holder of any Pledged Senior Notes that are subject to a Failed Final Remarketing, and any Senior Notes that are a component of a Corporate Unit with respect to which the Holder has notified the Purchase Contract Agent of his intent to effect Cash Settlement and failed to deliver the Purchase Price pursuant to Section 5.02(e)(ii) shall be deemed to have exercised such Holder's Put Right with respect to such Senior Notes and to have authorized the Collateral Agent to pay, in the manner provided for in the Pledge Agreement, the Purchase Price for the shares of Common Stock to be issued under the related Purchase Contract from a portion of the Proceeds of the Put Right in full satisfaction of such Holder's obligations under the related Purchase Contract; provided that if the Company shall fail to pay the Put Price when due, the Company shall be deemed to have netted such Holder's obligation to pay the Company the Purchase Price under the Purchase Contracts against the Company's obligation to pay the Put Price, in full satisfaction of such Holder's obligation under the Purchase Contracts. (d) (i) Unless a Holder of a Treasury Unit or a Corporate Unit (if the Treasury Portfolio has replaced the Senior Notes as a component of such Corporate Unit) 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 5.07 or a Cash Merger 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(b), each Holder of a Treasury Unit or a Corporate Unit who intends to effect Cash Settlement of the underlying Purchase Contract shall so notify the Purchase Contract Agent by use of a notice in substantially the form of Exhibit E hereto prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date. Promptly following 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, the Purchase Contract Agent shall notify the Collateral Agent of the receipt of such notices from such Holders intending to make a Cash Settlement. Holders of Treasury Units may make Cash Settlements only in integral multiples of ____ Corporate Units. (ii) A Holder of a Treasury Unit or a Corporate Unit (if the Treasury Portfolio has replaced the Senior Note as a component of such Corporate Unit) who has so notified the Purchase Contract Agent of its intention to make a Cash Settlement in accordance with Section 5.02(d)(i) above shall pay the Purchase Price to the Collateral Agent for 41 deposit in the Collateral Account prior to 5:00 p.m. (New York City time) on the fourth 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 so received shall be invested promptly by the Securities Intermediary in Permitted Investments pursuant to written instructions received from the Company 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 Collateral Agent 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 distributed to the Purchase Contract Agent when received for payment to the Holder. (iii) If a Holder of a Treasury Unit or Corporate Unit (if the Treasury Portfolio has replaced the Senior Note as a component of such Corporate Unit) fails to notify the Purchase Contract Agent of its intention to make a Cash Settlement in accordance with Section 5.02(d)(i), or does notify the Purchase Contract Agent as provided in Section 5.02(d)(i) of its intention to pay the Purchase Price in cash, but fails to make such payment as required by Section 5.02(d)(ii), then upon the maturity of the Pledged Treasury Securities or the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio held by the Securities Intermediary on or prior to the Business Day immediately preceding the Purchase Contract Settlement Date, the principal amount of the Treasury Securities or the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio received by the Collateral Agent 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 of such Holder's obligation to pay such Purchase Price under the related Purchase Contracts without receiving any instructions from the Holder. In the event the sum of the Proceeds from the related Pledged Treasury Securities or appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio and the Proceeds from such Permitted Investments is in excess of the aggregate Purchase Price, 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 Units or Corporate Units when received. (e) (i) Each Holder of a Corporate Unit who intends to effect a Cash Settlement of the underlying Purchase Contract following a Failed Final Remarketing shall so notify the Purchase Contract Agent by use of a notice in substantially the form of Exhibit E hereto prior to 5:00 p.m. (New York City time) on the second Business Day immediately preceding the Purchase Contract Settlement Date. Promptly following 5:00 p.m. (New York City time) on the second Business Day immediately preceding the Purchase Contract Settlement Date, the Purchase Contract Agent shall notify the Collateral Agent and the Indenture Trustee of the receipt of such notices from Holders intending to make a Cash Settlement. (ii) A Holder of a Corporate Unit who has so notified the Purchase Contract Agent of its intention to effect a Cash Settlement shall pay the Purchase Price to the 42 Collateral Agent for deposit in the Collateral Account prior to 5:00 p.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 so received 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 Corporate Unit does not notify the Purchase Contract Agent of its intention to make a Cash Settlement in accordance with Section 5.02(e)(i) above, or does notify the Purchase Contract Agent in accordance with Section 5.02(e)(i) above but fails to make such payment as required by Section 5.02(e)(ii) above, such Holder shall be deemed to have automatically exercised such Holder's Put Right following a Failed Final Remarketing as described in paragraph Section 5.02(c)(iii) above. (f) Promptly after 5:00 p.m. (New York City time) on the fourth Business Day preceding the Purchase Contract Settlement Date, the Collateral Agent, based on cash payments received by the Collateral Agent pursuant to Section 5.02(b)(ii) hereof, shall promptly notify the Purchase Contract Agent and the Indenture Trustee of the aggregate principal amount of Senior Notes to be tendered for purchase in the Remarketing in a notice pursuant to the terms of the Pledge Agreement. (g) Promptly after 5:00 p.m. (New York city time) on the Business Day preceding the Purchase Contract Settlement Date, the Collateral Agent, based on cash payment received by the Collateral Agent pursuant to Section 5.02(e)(ii) hereof, shall promptly notify the Purchase Contract Agent and the Indenture Trustee of the aggregate principal amount of Senior Notes pursuant to which a Put Right has been automatically exercised pursuant to Section 5.02(c)(iii) hereof. (h) 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. (i) Upon Cash Settlement of any Purchase Contract: (i) the Collateral Agent will in accordance with the terms of the Pledge Agreement cause the Pledged Senior Notes, the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio or the Pledged Treasury Securities, as the case may be, underlying the relevant Units to be released from the Pledge, free and clear of any security interest of the 43 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 Senior Notes, or the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in 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 Senior Notes, or the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in 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 where such property is held). (j) The obligations of the Holders to pay the Purchase Price are non-recourse obligations and, except to the extent satisfied by Early Settlement, Cash Merger Early Settlement or Cash Settlement, are payable solely out of the proceeds of any Collateral pledged to secure the obligations of the Holders, and in no event will Holders be liable for any deficiency between the proceeds of the disposition of Collateral and the Purchase Price. (k) 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 Units unless the Company shall have received payment 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, an Early Settlement or a Cash Merger Early Settlement shall have occurred, subject to Section 5.04(b), on the Purchase Contract Settlement Date upon receipt of payment in full of the aggregate Purchase Price payable on all Outstanding Units, the Company shall issue and deposit with the Purchase Contract Agent, for the benefit of the Holders of the Outstanding Units, 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. Subject to the foregoing, upon surrender of a Certificate to the Purchase Contract Agent on or after the Purchase Contract Settlement Date, Early Settlement Date or Cash Merger Early Settlement Date, as the case may be, together with settlement instructions thereon duly completed and executed, the Holder of such Certificate shall be entitled to receive forthwith in exchange therefor a certificate representing that number of newly issued whole shares of Common Stock which such Holder is entitled to receive pursuant to the provisions of this Article V (after taking into account all Units then held by such Holder), together with cash in lieu of 44 fractional shares as provided in Section 5.09 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 (but excluding any Depositary or nominee thereof), no such registration shall be made unless the Person requesting such registration has paid any transfer and other taxes required by reason of such registration in a name other than that of the registered Holder of the Certificate evidencing such 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. (i) 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 close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by dividing such Settlement Rate by a fraction of which: (A) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination; and (B) the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective immediately at the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (i), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company agrees that it shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (ii) In case the Company shall issue rights, options or warrants, other than pursuant to any dividend reinvestment plans or share purchase plans, to all holders of its Common Stock (that are not available on an equivalent basis to Holders of the Units upon settlement of the Purchase Contracts underlying such Units) entitling such holders of the Common Stock, for a period expiring within 45 days after the record date for the determination of stockholders entitled to receive such rights, options or warrants, to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price per share of the Common Stock on the date of announcement of such issuance, the Settlement Rate in effect at the close of business on the date of such 45 announcement shall be increased by dividing such Settlement Rate by a fraction of which: (A) the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date of such announcement plus the number of shares of Common Stock 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 (B) the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date of such announcement plus the number of shares of Common Stock so offered for subscription or purchase, such increase to become effective immediately after the opening of business on the Business Day following the date of such announcement. The Company agrees that it shall notify the Purchase Contract Agent if any issuance of such rights, warrants or options is cancelled or not completed following the announcement thereof and the Settlement Rate shall thereupon be readjusted to the Settlement Rate in effect immediately prior to the date of such announcement. For the purposes of this paragraph (ii), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of shares of Common Stock. The Company agrees that it shall not issue any such rights, warrants or options in respect of shares of Common Stock held in the treasury of the Company. (iii) In case outstanding shares of Common Stock shall be subdivided or split into a greater number of shares of Common Stock, the Settlement Rate in effect at the close of business on the day preceding the day upon which such subdivision or split becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Settlement Rate in effect at the close of business on the day preceding the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately at the opening of business on the day following the day upon which such subdivision, split or combination becomes effective. (iv) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including shares of capital stock, securities, cash and property but excluding any rights, warrants or options referred to in paragraph (ii) of this Section 5.04(a), any dividend or distribution paid exclusively in cash and any dividend or distribution referred to in paragraph (i) of this Section 5.04(a)), the Settlement Rate in effect at the close of business on the date fixed for the determination of stockholders entitled to receive such distribution shall be adjusted by dividing such rate by a fraction of which: (A) the numerator shall be the Current Market Price per share of Common Stock on the date fixed for such determination less the then fair market 46 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) of the portion of the assets or evidences of indebtedness so distributed applicable to one share of Common Stock; and (B) the denominator shall be such Current Market Price per share of Common Stock, such adjustment to become effective at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such distribution. In any case in which this paragraph (iv) is applicable, paragraph (ii) of this Section 5.04(a) shall not be applicable. In the event that such dividend or distribution is not so paid or made, 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. (v) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any cash that is distributed in a Reorganization Event to which Section 5.04(b) applies, as part of a distribution referred to in paragraph (iv) of this Section 5.04(a) or as a regular quarterly cash distribution) in an aggregate amount that, combined together with (I) the aggregate amount of any other distributions (other than regular quarterly cash distributions) to all holders of its Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution (the "Trailing 12 Month Period") and in respect of which no adjustment pursuant to this paragraph (v) or paragraph (vi) of this Section has been made and (II) the aggregate amount of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) of consideration (other than consideration payable in respect of any odd-lot tender offer) payable in respect of any tender or exchange offer by the Company or any of its subsidiaries and calculated as of the expiration of such tender or exchange offer for all or any portion of the Common Stock concluded within the Trailing 12 Month Period and in respect of which no adjustment pursuant to this paragraph (v) or paragraph (vi) of this Section has been made, exceeds ___% of the product of the Current Market Price per share of the Common Stock on the date for the determination of holders of shares of Common Stock entitled to receive such distribution multiplied by the number of shares of Common Stock outstanding on such date, then, in such case, the Settlement Rate in effect at the close of business on such record date shall be adjusted by dividing such rate by a fraction of which: (A) the numerator shall be the Current Market Price of Common Stock on such record date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock; and (B) the denominator shall be the Current Market Price of Common Stock, such increase to be effective at 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 47 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 Unit shall have the right to receive upon settlement of the Units the amount of cash such Holder would have received had such Holder settled each Unit 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. (vi) If the Company or any subsidiary of the Company shall make a tender or exchange offer (other than any odd-lot tender offer) for all or any portion of the Common Stock and upon expiration of such tender or exchange offer (as amended upon the expiration thereof) the Company or its subsidiary shall be required to pay to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of Purchased Shares (as herein defined) any consideration, then if the sum of (I) the fair market value of the aggregate consideration to be paid in such tender offer or exchange offer (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) plus (II) 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 (other than consideration payable in respect of any odd-lot tender 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 (vi) has been made, plus (III) the aggregate amount of any distributions (other than regular quarterly cash 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 (v) has been made, exceeds ___% 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, the Settlement Rate in effect at the close of business on the day of the Expiration Time shall be adjusted by dividing by a fraction: (A) 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 date of the Expiration Time less (B) the amount of cash plus the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the transactions described in clauses (I), (II) and (III) 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 48 (B) 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 to as the "Purchased Shares"), such adjustment to become effective at the opening of business on the date following the date of the Expiration Time. (vii) The reclassification of Common Stock into securities including securities other than Common Stock (other than any reclassification upon a Reorganization Event to which Section 5.04(b) applies) shall be deemed to involve: (A) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of stockholders entitled to receive such distribution" and the "date fixed for such determination" within the meaning of paragraph (iv) of this Section); and (B) a subdivision, split or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision or split becomes effective" or "the day upon which such combination becomes effective", as the case may be, and "the day upon which such subdivision, split or combination becomes effective" within the meaning of paragraph (iii) of this Section). (viii) The "Current Market Price" per share of Common Stock on any date of determination means the average of the daily Closing Prices for the five consecutive Trading Days selected by the Company commencing not more than thirty (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 regular way on such exchange or in such market without the right to receive such issuance or distribution. (ix) All adjustments to the Settlement Rate shall be calculated to the nearest __/______ of a share of Common Stock (or if there is not a nearest __/______ of a share, to the next lower __/______ 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. 49 (x) 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 the Board of Directors considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes or for any other reason. (xi) The Company has entered into an Amended and Restated Rights Agreement, dated as of February 5, 2003 (the "Rights Agreement"), with UMB Bank, N.A., as rights agent (the "Rights Agent") pursuant to which share purchase rights (the "Rights") have been, and may in the future be, issued in respect of shares of Common Stock. Each share of Common Stock issued upon settlement of any Purchase Contract pursuant to this Article V shall be entitled to receive the appropriate number of Rights, if any, and the certificates representing the Common Stock issued upon such settlement shall bear such legends, if any, in each case as provided by and subject to the terms of the Rights Agreement as in effect at the time of such settlement. If after the date of this Agreement the Rights separate from the Common Stock in accordance with the provisions of the Rights Agreement so that a Holder would not be entitled to receive any Rights in respect of the Common Stock issuable upon settlement of such Purchase Contract, the Settlement Rate will be adjusted as provided in this Section 5.04 on the separation date, subject to readjustment in the event of the expiration, termination or redemption of the Rights. In lieu of any such adjustment, the Company may amend the Rights Agreement to provide that upon settlement Holders will receive, in addition to the Common Stock issuable upon such settlement, the Rights that would have attached to such shares of Common Stock if the Rights had not become separated from the Common Stock pursuant to the provisions of the Rights Agreement. If the Company hereafter adopts any stockholder rights plan similar to the Rights Agreement, a Holder shall be entitled to receive upon settlement of its Purchase Contracts in addition to the shares of Common Stock issuable upon settlement the related rights for the Common Stock whether or not the rights under the future stockholder rights plan have separated from the Common Stock at the time of settlement but otherwise subject to the generally applicable terms of such plan and no additional adjustment to the Settlement Rate shall be made for the future stockholder rights plan under this Section 5.04. (b) Adjustment for Consolidation, Merger or Other Reorganization Event. (i) In the event of: (A) any consolidation or merger of the Company with or into another Person (other than a merger or consolidation in which the Company is the continuing corporation and in which the shares of Common Stock outstanding immediately prior to the merger or consolidation are not exchanged for cash, securities or other property of the Company or another corporation); (B) any sale, transfer, lease or conveyance to another Person of the property of the Company as an entirety or substantially as an entirety; 50 (C) any statutory share exchange of the Company with another Person (other than in connection with a merger or acquisition); or (D) any liquidation, dissolution or termination of the Company other than as a result of or after the occurrence of a Termination Event (any event described in clauses (A), (B), (C) and (D), a "Reorganization Event"), the Settlement Rate will be adjusted to provide that each Holder of Units will receive on the Purchase Contract Settlement Date with respect to each Purchase Contract forming a part thereof, the kind and amount of securities, cash and other property receivable upon such Reorganization Event (without any interest thereon, and without any right to dividends or distribution thereon which have a record date that is prior to the Purchase Contract Settlement Date) by a Holder of the number of shares of Common Stock issuable on account of each Purchase Contract if the Purchase Contract Settlement Date had occurred immediately prior to such Reorganization Event, assuming such Holder of Common Stock is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be (any such Person, a "Constituent Person"), or an Affiliate of a Constituent Person to the extent such Reorganization Event provides for different treatment of Common Stock held by Affiliates of the Company and non-affiliates and such Holder failed to exercise its rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such Reorganization Event (provided that if the kind or amount of securities, cash and other property receivable upon such Reorganization Event is not the same for each share of Common Stock held immediately prior to such Reorganization Event by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this Section 5.04(b)(i) the kind and amount of securities, cash and other property receivable upon such Reorganization Event by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). 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 Unit shall have the rights provided by this Section 5.04(b)(i). Such supplemental agreement shall provide for adjustments which, for events subsequent to the effective date of such supplemental agreement, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5.04. The above provisions of this Section 5.04 shall similarly apply to successive Reorganization Events. (ii) In the event of a consolidation or merger of the Company with or into another Person, or 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 each case in which __% or more of the total consideration paid to the Company's stockholders consists of cash or cash equivalents (a 51 "Cash Merger"), then a Holder of a Unit may settle ("Cash Merger Early Settlement") its Purchase Contract, upon the conditions set forth below, at the Settlement Rate in effect immediately prior to the closing of the Cash Merger; provided that (A) the Cash Merger Early Settlement Date (as defined below) is no later than the fifth Business Day immediately preceding the Purchase Contract Settlement Date and (B) no Cash Merger Early Settlement will be permitted pursuant to this Section 5.04(b)(ii) unless, at the time such Cash Merger Early Settlement is effected, there is an effective Registration Statement with respect to any securities to be issued and delivered in connection with such Cash Merger Early Settlement, if such a Registration Statement is required (in the view of counsel, which need not be in the form of a written opinion, for the Company) under the Securities Act. If such a Registration Statement is so required, the Company covenants and agrees to use commercially reasonable efforts to (x) have in effect a Registration Statement covering any securities to be delivered in respect of the Purchase Contracts being settled and (y) provide a Prospectus in connection therewith, in each case in a form that may be used in connection with such Cash Merger Early Settlement. Within five Business Days of the completion of a Cash Merger, the Company shall provide written notice to Holders of Units of such completion of a Cash Merger, which shall specify the deadline for submitting the notice to settle early in cash pursuant to this Section 5.04(b)(ii), the date on which such Cash Merger Early Settlement shall occur (which date shall be 10 days after the date of such written notice by the Company, but which shall in no event be later than the fifth Business Day immediately preceding the Purchase Contract Settlement Date) (the "Cash Merger Early Settlement Date"), the applicable Settlement Rate and the amount (per share of Common Stock) of cash, securities and other consideration receivable by the Holder upon settlement. In addition, if a Holder effects a Cash Merger Early Settlement of some or all of its Purchase Contracts, such Holder shall be entitled to receive, on the Cash Merger Early Settlement Date, the aggregate amount of any accrued and unpaid Contract Adjustment Payments since the immediately preceding Payment Date with respect to such Purchase Contracts. The Company shall pay such amount as a credit against the amount otherwise payable by the Holders to effect such Cash Merger Early Settlement. Corporate Units Holders and Treasury Units Holders may only effect Cash Merger Early Settlement pursuant to this Section 5.04(b)(ii) in integral multiples of __ Corporate Units or Treasury Units, as the case may be. If the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, Corporate Units Holders may only effect Cash Merger Early Settlement pursuant to this Section 5.04(b)(ii) in multiples of ______ Corporate Units. Other than the provisions relating to timing of notice and settlement, which shall be as set forth above, the provisions of Section 5.01(a) shall apply with respect to a Cash Merger Early Settlement pursuant to this Section 5.04(b)(ii). In order to exercise the right to effect Cash Merger Early Settlement with respect to any Purchase Contracts, the Holder of the Certificate evidencing Units shall deliver, no later than 5:00 p.m. (New York City time) on the third Business Day immediately preceding the Cash Merger Early Settlement Date, such Certificate to the Purchase Contract Agent at the Corporate Trust Office duly endorsed for transfer to the Company 52 or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds) in an amount equal to the product of (A) the Stated Amount times (B) the number of Purchase Contracts with respect to which the Holder has elected to effect Cash Merger Early Settlement. If a Holder properly effects an effective Cash Merger Early Settlement in accordance with the provisions of this Section 5.04(b)(ii), the Company will deliver (or will cause the Collateral Agent to deliver) to the Holder on the Cash Merger Early Settlement Date: (A) the kind and amount of securities, cash and other property receivable upon such Cash Merger by a Holder of the number of shares of Common Stock issuable on account of each Purchase Contract if the Purchase Contract Settlement Date had occurred immediately prior to such Cash Merger (based on the Settlement Rate in effect at such time), assuming such Holder of Common Stock is not a Constituent Person or an Affiliate of a Constituent Person to the extent such Cash Merger provides for different treatment of Common Stock held by Affiliates of the Company and non-affiliates and such Holder failed to exercise its rights of election, if any, as to the kind or amount of securities, cash and other property receivable upon such Cash Merger (provided that if the kind or amount of securities, cash and other property receivable upon such Cash Merger is not the same for each non-electing share, then for the purpose of this Section 5.04(b)(ii), the kind and amount of securities, cash and other property receivable upon such Cash Merger by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). For the avoidance of doubt, for the purposes of determining the Adjusted Applicable Market Value (in connection with determining the appropriate Settlement Rate to be applied in the foregoing sentence), the date of the closing of the Cash Merger shall be deemed to be the Purchase Contract Settlement Date; (B) the Senior Notes, the Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, related to the Purchase Contracts with respect to which the Holder is effecting a Cash Merger Early Settlement; and (C) if so required under the Securities Act, a Prospectus as contemplated by this Section 5.04(b)(ii). (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. (d) The Corporate Units or the Treasury Units of the Holders who do not elect Cash Merger Early Settlement in accordance with the foregoing will continue to remain outstanding and be subject to settlement on the Purchase Contract Settlement Date in accordance with the terms hereof. 53 SECTION 5.05. NOTICE OF ADJUSTMENTS AND CERTAIN OTHER EVENTS. (a) Whenever the Settlement Rate is adjusted as herein provided, the Company shall 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): (i) 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) provide a written notice to the Holders of the Units of the occurrence of such event and a statement in reasonable detail setting forth the method by which the adjustment to the Settlement Rate 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 Units 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 be fully authorized and protected in relying on any Officers' Certificate delivered pursuant to Section 5.05(a)(i) and any adjustment contained therein and the Purchase Contract Agent shall not be deemed to have knowledge of any adjustment unless and until it has received such certificate. 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 Contract Adjustment Payments (including any accrued and unpaid Contract Adjustment 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, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon and after the occurrence of a Termination Event, the Units shall thereafter represent the right to receive the Senior Notes, the Treasury Securities or the appropriate Applicable Ownership Interests in the Treasury Portfolio, as the case may be, forming part of such Units, in 54 accordance with the provisions of Section 4.04 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. EARLY SETTLEMENT. (a) Subject to and upon compliance with the provisions of this Section 5.07, at the option of the Holder thereof, Purchase Contracts underlying Units may be settled early ("Early Settlement") at any time prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date; provided that no Early Settlement will be permitted pursuant to this Section 5.07 unless, at the time such Early Settlement is effected, there is an effective Registration Statement with respect to any securities to be issued and delivered in connection with such Early Settlement, if such a Registration Statement is required (in the view of counsel, which need not be in the form of a written opinion, for the Company) under the Securities Act. If such a Registration Statement is so required, the Company covenants and agrees to use commercially reasonable efforts to (i) have in effect a Registration Statement covering any securities to be delivered in respect of the Purchase Contracts being settled and (ii) provide a Prospectus in connection therewith, in each case in a form that may be used in connection with such Early Settlement. (b) In order to exercise the right to effect Early Settlement with respect to any Purchase Contracts, the Holder of the Certificate evidencing Units shall deliver, at any time prior to 5:00 a.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, such Certificate to the Purchase Contract Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed and accompanied by payment (payable to the Company in immediately available funds) in an amount (the "Early Settlement Amount") equal to the sum of: (i) the product of (A) the Stated Amount times (B) the number of Purchase Contracts with respect to which the Holder has elected to effect Early Settlement, plus (ii) if such delivery is made with respect to any Purchase Contracts during the period from the close of business on any Record Date next preceding any Payment Date to the opening of business on such Payment Date, an amount equal to the Contract Adjustment Payments payable on such Payment Date with respect to such Purchase Contracts. Except as provided in the immediately preceding sentence, no payment shall be made upon Early Settlement of any Purchase Contract on account of any Contract Adjustment Payments accrued on such Purchase Contract or on account of any dividends on the Common Stock issued upon such Early Settlement. If the foregoing requirements are first satisfied with respect to Purchase Contracts underlying any Units at or prior to 5:00 p.m. (New York City time) on a Business Day, such day shall be the "Early Settlement Date" with respect to such Units and if such requirements are first satisfied after 5:00 p.m. (New York City time) on a Business Day 55 or on a day that is not a Business Day, the "Early Settlement Date" with respect to such Units shall be the next succeeding Business Day. Upon the receipt of such Certificate and Early Settlement Amount from the Holder, the Purchase Contract Agent shall pay to the Company such Early Settlement Amount, the receipt of which payment the Company shall confirm in writing. The Purchase Contract Agent shall then, in accordance with Section 4.06 of the Pledge Agreement, notify the Collateral Agent that (A) such Holder has elected to effect an Early Settlement, which notice shall set forth the number of such Purchase Contracts as to which such Holder has elected to effect Early Settlement, (B) the Purchase Contract Agent has received from such Holder, and paid to the Company as confirmed in writing by the Company, the related Early Settlement Amount and (C) all conditions to such Early Settlement have been satisfied. Holders of Treasury Units may only effect Early Settlement pursuant to this Section 5.07 in integral multiples of __ Treasury Units. If the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, Corporate Units Holders may only effect Early Settlement pursuant to this Section 5.07 in integral multiples of ______ Corporate Units. Upon Early Settlement of the Purchase Contracts, the rights of the Holders to receive and the obligation of the Company to pay any Contract Adjustment Payments (including any accrued and unpaid Contract Adjustment Payments) with respect to such Purchase Contracts shall immediately and automatically terminate. (c) Upon Early Settlement of Purchase Contracts by a Holder of the related Units, the Company shall issue, and the Holder shall be entitled to receive, ______ shares of Common Stock on account of each Purchase Contract as to which Early Settlement is effected (the "Early Settlement Rate"). The Early Settlement Rate shall be adjusted in the same manner and at the same time as the Settlement Rate is adjusted pursuant to Section 5.04. (d) No later than the third Business Day after the applicable Early Settlement Date, the Company shall cause: (i) the shares of Common Stock issuable upon Early Settlement of Purchase Contracts to be issued and delivered, together with payment in lieu of any fraction of a share, as provided in Section 5.09; and (ii) the related Senior Notes or the Applicable Ownership Interests in the Treasury Portfolio, as applicable, in the case of Corporate Units, or the related Treasury Securities, in the case of Treasury Units, to be released from the Pledge by the Collateral Agent and transferred, in each case, to the Purchase Contract Agent for delivery to the Holder thereof or its designee. (e) Upon Early Settlement of any Purchase Contracts, and subject to receipt of shares of Common Stock from the Company and the Senior Notes, the Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, from the Securities Intermediary, as applicable, the Purchase Contract Agent shall, in accordance with the instructions provided by the Holder thereof on the applicable form of Election to Settle Early on the reverse of the Certificate evidencing the related Units: 56 (i) transfer to the Holder the Senior Notes, the Applicable Ownership Interests in the Treasury Portfolio or Treasury Securities, as the case may be, forming a part of such Units, (ii) deliver to the Holder a certificate or certificates for the full number of shares of Common Stock issuable upon such Early Settlement, together with payment in lieu of any fraction of a share, as provided in Section 5.09, and (iii) if so required under the Securities Act, deliver a Prospectus for the shares of Common Stock issuable upon such Early Settlement as contemplated by Section 5.07(a). (f) In the event that Early Settlement is effected with respect to Purchase Contracts underlying less than all the Units evidenced by a Certificate, upon such Early Settlement the Company shall execute and the Purchase Contract Agent shall execute on behalf of the Holder, authenticate and deliver to the Holder thereof, at the expense of the Company, a Certificate evidencing the Units as to which Early Settlement was not effected. (g) A Holder of a Unit who effects Early Settlement may elect to have the Senior Notes no longer a part of a Corporate Unit remarketed in accordance with the provisions of Section 5.02. 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 or Cash Merger Early Settlement of any Purchase Contracts. If Certificates evidencing more than one Purchase Contract shall be surrendered for settlement at one time by the same Holder, the number of full shares of Common Stock which shall be delivered upon settlement shall be computed on the basis of the aggregate number of Purchase Contracts evidenced by the Certificates so surrendered. Instead of any fractional share of Common Stock which would otherwise be deliverable upon settlement of any Purchase Contracts on the Purchase Contract Settlement Date, or upon Early Settlement or Cash Merger Early Settlement, the Company, through the Purchase Contract Agent, shall make a cash payment in respect of such fractional interest in an amount equal to the percentage of such fractional share times the Applicable Market Value calculated as if the date of such settlement were the Purchase Contract Settlement Date. 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 Unit 57 or any issuance of a share of Common Stock in a name other than that of the registered Holder of a Certificate surrendered in respect of the Units evidenced thereby, other than in the name of the Purchase Contract Agent, as custodian for such Holder, and the Company shall not be required to issue or deliver such share certificates or Certificates unless 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. CONTRACT ADJUSTMENT PAYMENTS. (a) Subject to Section 5.11(d), the Company shall pay, on each Payment Date, the Contract Adjustment 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 relating to such Payment Date. The Contract Adjustment Payments will be payable at the office of the Purchase Contract Agent in the Borough of Manhattan, New York City maintained for that purpose. If the book-entry system for the Units has been terminated, the Contract Adjustment Payments will be payable, at the option of the Company, by check mailed to the address of the Person entitled thereto at such Person's address as it appears on the Security Register, or by wire transfer to the account designated by such Person by a prior written notice to the Purchase Contract Agent. If any date on which Contract Adjustment Payments are to be made is not a Business Day, then payment of the Contract Adjustment 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); provided that if such Business Day is in the next succeeding calendar year, then payment of the Contract Adjustment Payments will be made on the Business Day immediately preceding such Business Day. Contract Adjustment Payments payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. The Contract Adjustment Payments will accrue from ____________, ____. (b) Upon the occurrence of a Termination Event, the Company's obligation to pay future Contract Adjustment Payments (including any accrued Contract Adjustment Payments) shall cease. (c) Each Certificate delivered under this Agreement upon registration of transfer of or in exchange for or in lieu of (including as a result of a Collateral Substitution or the recreation of Corporate Units) any other Certificate shall carry the right to accrued and unpaid Contract Adjustment Payments, which right was carried by the Purchase Contracts underlying such other Certificates. (d) In the case of any Unit with respect to which Early Settlement or Cash Merger Early Settlement of the underlying Purchase Contract is effected on a date that is after any Record Date and prior to or on the next succeeding Payment Date, Contract Adjustment Payments otherwise payable on such Payment Date shall be payable on such Payment Date notwithstanding such Early Settlement or Cash Merger Early Settlement, and such Contract Adjustment Payments shall be paid to the Person in whose name the Certificate evidencing such Unit is registered at the close of business on such Record Date.

(o) The Company shall give prompt written notice to the Purchase Contract Agent of any fact known to the Company that would prohibit the making of any payment of moneys to or by the Purchase Contract Agent in respect of the Units pursuant to the provisions of this Section. Notwithstanding the provisions of Section 5.11(e) through (q) or any other provisions of this Agreement, the Purchase Contract Agent shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of moneys to or by the Purchase Contract Agent, or the taking of any other action by the Purchase Contract Agent, unless and until the Purchase Contract Agent shall have received written notice thereof mailed or delivered to the Purchase Contract Agent at its Corporate Trust Office from the Company, any Holder, or the holder or representative of any Senior Indebtedness; provided that if at least two Business Days prior to the date upon which by the terms hereof any such moneys may become payable for any purpose, the Purchase Contract Agent shall not have received with respect to such moneys the notice provided for in this Section, then, anything herein contained to the contrary notwithstanding, the Purchase Contract Agent shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary that may be received by it within two Business Days prior to or on or after such date. (p) The Purchase Contract Agent in its individual capacity shall be entitled to all the rights set forth in this Section with respect to any Senior Indebtedness at the time held by it, to the same extent as any other holder of Senior Indebtedness and nothing in this Agreement shall deprive the Purchase Contract Agent of any of its rights as such holder. (q) No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Agreement, regardless of any knowledge thereof which any such holder may have or be otherwise charged with. 62 (r) Nothing in this Section 5.11 shall apply to claims of, or payments to, the Purchase Contract Agent under or pursuant to Section 7.07.

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. 63 SECTION 6.04. DELAY OR OMISSION NOT WAIVER. No delay or omission of any Holder to exercise any right upon a default or remedy upon a default shall impair any such right or remedy or constitute a waiver of any such right.

In the event of the Company's failure to pay the Put Price when due, the Company shall be deemed to have netted such Holder's obligation to pay the Company the Purchase Price under the Purchase Contracts against the Company's obligation to pay the Put Price, in full satisfaction of such Holder's obligation under the Purchase Contracts. The Company shall not be obligated to issue any shares of Common Stock in respect of a Purchase Contract or deliver any certificates therefor to the Holder unless it shall have received payment of the aggregate Purchase Price for the shares of Common Stock to be purchased thereunder in the manner set forth in the Purchase Contract Agreement. 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 Senior Notes or the appropriate Applicable Ownership Interests (as specified in clause A-8 (i) of the definition of such term) in the Treasury Portfolio forming a part of each Corporate Unit from the Pledge. A Corporate Unit shall thereafter represent the right to receive the Senior Note or the appropriate Applicable Ownership Interests in the Treasury Portfolio forming a part of such Corporate Units in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. Under the terms of the Pledge Agreement and the Purchase Contract Agreement, the Purchase Contract Agent will be entitled to exercise the voting and any other consensual rights pertaining to the Pledged Senior Notes, but only to the extent instructed in writing by the Holders. Upon receipt of notice of any meeting at which holders of Senior Notes are entitled to vote or upon any solicitation of consents, waivers or proxies of holders of Senior Notes, the Purchase Contract Agent shall, as soon as practicable thereafter, mail, first class, postage pre-paid, to the Corporate Units Holders a notice: (1) containing such information as is contained in the notice or solicitation; (2) stating that each Corporate Units 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 Senior Notes entitled to vote) shall be entitled to instruct the Purchase Contract Agent as to the exercise of the voting rights pertaining to the Senior Notes constituting a part of such Holder's Corporate Units; and (3) stating the manner in which such instructions may be given. Upon the written request of the Corporate Units Holders 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 aggregate principal amount of Senior Notes, as to which any particular voting instructions are received. In the absence of specific instructions from the Holder of a Corporate Unit, the Purchase Contract Agent shall abstain from voting the Senior Note evidenced by such Corporate Unit. The Company hereby agrees, if applicable, to solicit Holders of Corporate Units to timely instruct the Purchase Contract Agent in order to enable the Purchase Contract Agent to vote the Senior Notes. The Holders of Corporate Units shall have no voting or other rights in respect of Common Stock. Upon the occurrence of a Special Event Redemption, the Collateral Agent shall surrender the Pledged Senior Notes against delivery of an amount equal to the aggregate Redemption Price of the Pledged Senior Notes and shall deposit the funds in the Collateral Account in exchange for the Pledged Senior 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 aggregate Redemption Amount of such funds to purchase on behalf of the Holders of Corporate Units the Treasury Portfolio and promptly (a) transfer the Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio to the Collateral Account to secure the obligations of each Holder of Corporate Units to purchase shares of Common Stock under the Purchase Contracts constituting a part of such Corporate Units, (b) transfer the Applicable Ownership Interests (as specified in clause (ii) of the definition of such term) in the Treasury Portfolio to the Purchase Contract Agent for the benefit of the Holders of A-9 such Corporate Units and (c) remit the remaining portion of such funds to the Purchase Contract Agent for payment to the Holders of such Corporate Units. Upon the occurrence of a Successful Remarketing of Senior Notes prior to the Final Remarketing Date, pursuant to the terms of the Remarketing Agreement, the Remarketing Agent will apply an amount equal to the Treasury Portfolio Purchase Price to purchase on behalf of the Holders of Corporate Units, the Treasury Portfolio, and, after deducting the Remarketing Fee to the extent permitted under the terms of the Remarketing Agreement, promptly remit the remaining portion of such proceeds of such Successful Remarketing to the Purchase Contract Agent for payment to the Holders of such Corporate Units. Following the occurrence of (i) a Special Event Redemption prior to the Purchase Contract Settlement Date, or (ii) a Successful Remarketing of the Senior Notes prior to the Final Remarketing Date, the Holders of Corporate Units and the Collateral Agent shall have such security interest rights and obligations with respect to the Applicable Ownership Interests in the Treasury Portfolio as the Holder of Corporate Units and the Collateral Agent had in respect of the Senior Notes, as the case may be, subject to the Pledge of the Applicable Ownership Interest (as specified in clause (i) of the definition of such term) as provided in the Pledge Agreement and any reference herein to the Senior Notes shall be deemed to be a reference to such Treasury Portfolio. The Corporate Units Certificates are issuable only in registered form and only in denominations of a single Corporate Unit and any integral multiple thereof. The transfer of any Corporate Units Certificate will be registered and Corporate Units 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 a Treasury Security for a Senior Note, thereby creating Treasury Units, shall be responsible for any fees or expenses payable in connection therewith. Except as provided in the Purchase Contract Agreement, for so long as the Purchase Contract underlying a Corporate Units remains in effect, such Corporate Units shall not be separable into its constituent parts, and the rights and obligations of the Holder of such Corporate Units in respect of the Senior Notes and Purchase Contract constituting such Corporate Units may be transferred and exchanged only as a Corporate Unit. Unless the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, and subject to the conditions set forth in the Purchase Contract Agreement, the Holder of Corporate Units may substitute, at any time prior to 5:00 p.m. (New York City time) on the fifth Business Day immediately preceding the Purchase Contract Settlement Date, for the Pledged Senior Notes securing such Holder's obligations under the related Purchase Contracts, Treasury Securities in an aggregate principal amount at maturity equal to the aggregate principal amount of the Pledged Senior Notes in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. From and after such Collateral Substitution, each Unit for which such Pledged Treasury Securities secures the Holder's obligation under the Purchase Contract shall be referred to as a "Treasury Unit". A Holder may make such Collateral Substitution only in integral multiples of ____ Corporate Units for ____ Treasury Units. A-10 If the Treasury Portfolio has replaced the Senior Notes as a component of the Corporate Units, a Holder may, at any time on or prior to the second Business Day immediately preceding the Purchase Contract Settlement Date, substitute Treasury Securities for the Applicable Ownership Interests in the Treasury Portfolio, but only in integral multiples of ______ Corporate Units. In such an event, the Holder shall transfer Treasury Securities to the Collateral Agent, and the Purchase Contract Agent shall instruct the Collateral Agent to release the Pledge of and transfer to the Holder the appropriate Applicable Ownership Interests in the Treasury Portfolio.

Contract Adjustment Payments will be payable at the office of the Company in New York City or the Corporate Trust Office of the Purchase Contract Agent.

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 Contract Adjustment Payments, shall immediately and automatically terminate, without the necessity of any notice or action by any Holder, the Purchase Contract Agent or the Company, if, on or prior to the Purchase Contract Settlement Date, a Termination Event shall have occurred. Upon the occurrence of a Termination Event, the Company shall promptly but in no event later than two Business Days thereafter give written notice to the Purchase Contract Agent, the Collateral Agent and the Holder, 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 Senior Notes or the appropriate Applicable Ownership Interests (as specified in clause (i) of the definition of such term) in the Treasury Portfolio, as the case may be, from the Pledge in accordance with the provisions of the Pledge Agreement.

A Treasury Unit shall thereafter represent the right to receive the Proceeds of the Treasury Security forming a part of such Treasury Unit, in accordance with the terms of the Purchase Contract Agreement and the Pledge Agreement. The Treasury Units Certificates are issuable only in registered form and only in denominations of a single Treasury Unit and any integral multiple thereof. The transfer of any Treasury Units Certificate will be registered and Treasury Units 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.
