Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous.

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

(e) The Company may set any day 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 on or prior to the applicable Expiration Date by Holders of the requisite number of Outstanding Units on such record date. Nothing contained in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and be of no effect), and nothing contained in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite number of Outstanding Units on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Purchase Contract Agent in writing and to each Holder of Units in the manner set forth in Section 1.6.

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

Section 1.5 Notices.

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

Section 1.6 Notice to Holders; Waiver.

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

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

The Company and the Holders from time to time of the Units, acting through the Purchase Contract Agent as their attorney-in-fact, irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum.

In any case where any Purchase Contract Settlement Date shall not be a Business Day, notwithstanding any other provision of this Agreement, the Corporate Unit Certificates or the Treasury Unit Certificates, Purchase Contracts shall not be settled on such date, but the Purchase Contracts shall be settled on the immediately following Business Day with the same force and effect as if performed on the Purchase Contract Settlement Date.

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

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

Each Certificate shall be dated the date of its authentication.

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

Section 3.4 Temporary Certificates.

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

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

If temporary Certificates are issued, the Company will cause definitive Certificates to be prepared without unreasonable delay.

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

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

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

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

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

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

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

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

Such Global Certificate 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 3.9. The Purchase Contract Agent shall enter into an agreement with the Depositary if so requested by the Company. Unless and until definitive, fully registered Certificates have been issued to Beneficial Owners pursuant to Section 3.9:

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

Section 3.8 Appointment of Successor Depositary.

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

Section 3.9 Definitive Certificates.

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

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

Section 3.10 Mutilated, Destroyed, Lost and Stolen Certificates.

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

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

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

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

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

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

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

Section 3.11 Persons Deemed Owners.

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

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

Section 3.12 Cancellation.

The Company may at any time deliver to the Purchase Contract Agent for cancellation any Certificates previously authenticated, executed and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the Purchase Contract Agent. No Certificates shall be authenticated, executed on behalf of the Holder and delivered in lieu of or in exchange for any Certificates cancelled as provided in this Section, except as expressly permitted by this Agreement. All cancelled Certificates held by the Purchase Contract Agent shall be disposed of by the Purchase Contract Agent in accordance with its customary procedures.

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

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

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

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

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

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

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

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

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

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

(i) cancel the related Corporate Units;

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

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

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

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

Section 3.14 Recreation of Corporate Units.

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

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

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

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

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

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

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

(i) cancel the related Treasury Units; and

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

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

Section 3.15 Transfer of Collateral upon Occurrence of Termination Event.

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

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

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

Section 3.16 No Consent to Assumption.

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

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

Upon the written request of the Holders of Corporate Units on such record date received by the Purchase Contract Agent at least six calendar days prior to such meeting or by the expiration date of any such solicitation, the Purchase Contract Agent shall endeavor insofar as practicable to vote or cause to be voted, in accordance with the instructions set forth in such requests, the maximum principal amount of Debt Securities as to which any particular voting instructions are received.

The Company covenants and agrees, and each Holder of a Certificate, by its acceptance thereof, likewise covenants and agrees, to be bound by the provisions of this paragraph.

Section 5.2 Purchase Contract Adjustment Payments.

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

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

Section 5.3 Payment of Purchase Price; Remarketing.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Section 5.4 Issuance of Shares of Common Stock.

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

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

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

Section 5.5 Adjustment of Settlement Rate and Early Settlement Rate.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

In the event of:

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

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

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

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

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

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

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

Section 5.6 Notice of Adjustments and Certain Other Events.

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

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

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

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

Section 5.7 Termination Event; Notice.

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

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

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.

(c) On the Merger Early Settlement Date, the Company shall cause to be delivered (i) the net cash, securities and other property to be received by such exercising Holder, equal to the Settlement Rate as adjusted pursuant to Section 5.5, in respect of the number of Purchase Contracts for which such Merger Early Settlement right was exercised pursuant to the applicable instructions contained in Section 5.4(b), (ii) the Company shall cause the number of shares of Common Stock issuable upon Merger Early Settlement, if any, of the related Purchase Contracts pursuant to Section 5.4, together with any payment in lieu of any fraction of a share, as provided in Section 5.12, to the Holder which has exercised its right to Cash Settlement, in accordance with Section 5.4 and (iii) the related Pledged Debt Securities, or if substituted therefore, the Pledged Treasury Portfolio Interest, in the case of Corporate Units, or Pledged 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.

Section 5.11 Optional Remarketing.

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.

The terms of this Corporate Unit Certificate include those stated herein and in the Purchase Contract Agreement. To the extent permitted by applicable law, in the event of an inconsistency between this Corporate Unit Certificate and the Purchase Contract Agreement, the terms of the Purchase Contract Agreement shall control. Capitalized terms used but not defined herein have the meanings ascribed thereto in the Purchase Contract Agreement.

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

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

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

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

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

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

A-5

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

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

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

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

A-6

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

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

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

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

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

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

A-7

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

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

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

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

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

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

6. Authorization of Purchase Contract Agent.

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

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

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

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

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

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

(FORM OF REVERSE OF TREASURY UNIT CERTIFICATE)

1. Purchase Contract Agreement; Purchase Contracts.

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

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

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

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

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

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

B-4

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

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

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

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

The Early Settlement Rate shall initially be equal to ___ shares of Common Stock per Purchase Contract and shall be adjusted in the same manner and at the same time as the Settlement Rate is adjusted as provided in the Purchase Contract Agreement.

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

No service charge shall be required for any such registration of transfer or exchange, but the Company and the Purchase Contract Agent may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. A Holder who elects to substitute Debt Securities for a Treasury Security, thereby creating Corporate Units, shall be responsible for any fees or expenses payable in connection therewith. Except as provided in the Purchase Contract Agreement, for so long as the

B-6

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

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

7. Amendment.

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